  【Background technique】

Disposable PVC gloves are an emerging industry, originated in the United States, gradually developed in Japan, and then entered Taiwan, China. With the increase of manufacturing costs in Taiwan, its production has gradually shifted to the mainland of China and has developed rapidly. At present, mainland China has become the world The PVC glove production base in China is the world's most important supplier of PVC gloves.

 The instability of the industry’s initial production technology, the non-standardization of process equipment, and the absence of relevant universities and scientific research institutions engaged in specialized technical research hindered the technical exchanges in the industry. Many factors on the one hand limit the improvement of industry technology, on the other hand. In this way, the industry technology still has a large room for improvement. With the continuous improvement of my country's machining accuracy and the maturity of industrial control technology, it provides a huge opportunity for the improvement of the technical level of the industry.

At present, the PVC glove production lines built in China are single-line, that is, each production line can only hang A/B hand molds, and the production efficiency is low. At the same time, the production process of PVC gloves belongs to the dipping process. Most of the energy consumption is concentrated in the oven part. The energy consumption is relatively large, mainly including heat loss from the heat conduction oil pipeline, heat loss from the oven, heat loss from chains, hand molds, and hand mold base High temperature flue gas exhaust heat loss, etc.

[Content of the invention]


 In order to overcome the shortcomings in the above technology, the purpose of the present invention is to provide a two-hand mold PVC glove production device, which can achieve the effect of reducing energy consumption while increasing the output of gloves.

 The technical solution adopted by the present invention to solve its technical problems is: a two-hand mold PVC glove production device, including a hand mold track line and a glove production line, the hand mold track line is located above the glove production line, and the hand mold track line is the two hand mold track line , Consists of two-hand mold main track and two-hand mold auxiliary track. The two-hand mold main track is an open "U"-shaped track, the two-hand mold auxiliary track is a single-sided double-layer track, and the glove production line has a "I"-shaped closed loop structure. Including the pre-release device, line 1 demolding device, line 2 demolding device, line 1 counting machine, line 2 counting machine, mold cleaning device, PVC trough, which are sequentially installed from the lower left corner of the "I" shape. PVC recovery tank, PVC drip section, PVC main oven, smoke collection section, PU feed tank, PU drip recovery tank, PU oven, line 2 crimping machine, line 2 trimming machine, line 1 crimping machine , Line 1 sizing machine, the smoke collecting section is connected with the PVC main oven and PU oven respectively, and the production line counterweight system is set between the smoke collecting section and the PU hopper.

 The two-hand mold track line changes the original one-hand mold production line to the two-hand mold production line. The single side of the production line is changed from one hand mold to two hand molds, which is divided into line 1 and line 2, and the corresponding glove production line Two hand molds are installed on the top of the equipment required to produce gloves. The glove "work" closed-loop production line is equipped with six runners, and the main track of the two-hand mold is set to the corresponding open "U"-shaped track to ensure that the production line is organized In the case of the same vehicle speed, the output can be doubled and the heat loss of part of the production line can be reduced.

 Compared with the prior art, the present invention has the following beneficial effects:

The invention provides a two-hand mold PVC glove production device, which changes the original one-hand mold track line to the two-hand mold track line, and part of the material of the hand mold seat is changed to a lighter and less rigid aluminum material, which reduces the number of hands. The accidental loss caused by the mold base to the production line; there is a cooling water washing tank between the smoke collecting section and the PU material trough to reduce the temperature of the hand mold to the appropriate temperature for dipping the material, avoiding the excessive temperature difference between the hand mold and the PU material due to drying The resulting performance is affected, and a small amount of active ions gathered on the surface of the PVC are cleaned, which is beneficial to the attachment of the PVC to the main track in the PVC main oven to have a lead screw, which can make the main track in the plasticization section of the glove. The wavy shape ensures the three-point thickness of the glove; the upper and lower parts of the PVC main oven are each laid with a layer of heat-conducting oil fin tubes. In addition to keeping the overall temperature in the PVC main oven balanced and stable, it can also be directly connected to the heat-conducting oil fin tubes. Radiant heat to improve the effect of plasticization; the glove production line turning wheel is equipped with a single-sided double-layer guard ring, which can reduce the force at the turning wheel of the glove production line and the collision between the hand molds; the turning wheel of the production line and the hand mold The special structure design of the seat handle ensures that when a certain single line is crimped and trimmed, the other single side can pass through from above. Compared with the traditional single-handed PVC production line, the invention not only improves the production efficiency of PVC gloves, but also effectively reduces the energy consumption value in the production process of PVC gloves.
