 disposable medical latex glove production line


 【Background technique】

The hand mold holder is an important part in the production line of disposable gloves (latex gloves, nitrile gloves, PVC gloves, household gloves), used to install glove molds. The existing hand mold base includes a chuck, a support shaft and a wheel disc. One end of the support shaft is movably arranged in the chuck through a bearing. The chuck is provided with a pin shaft that matches the conveyor chain of the glove production line. The pin is fixed on the chuck, the other end of the support shaft is provided with a thread, the roulette is sleeved on the support shaft at the threaded end, the edge of the roulette is provided with rims along the axial direction of the roulette, and the middle of the support shaft is sleeved with an elastic piece, One end of the elastic piece abuts against the elastic piece sleeve also sleeved on the support shaft and located on one side of the chuck, and the other end abuts against the wheel disc. The glove mold is installed on the roulette on the hand mold base.

The manufacturing process of disposable gloves is as follows: first dipping, that is, the glove mold rolls in the size tank, the glove material in the size tank is wrapped around the glove mold, and then the glove mold is rolled into the oven to dry, and then go through curling, Pre-release, demoulding, the disposable glove is finished. During the dipping process, the wheel on the hand mold seat rolls along the same metal guide rail on the disposable glove production line, thereby driving the glove mold to roll in the slurry tank. The chuck, the rotating disk and the support shaft are formed by stamping and then welded together. The dimensional accuracy of the entire hand mold base is low, and the deformation is large. In particular, the verticality and concentricity between the roulette and the support shaft are difficult to guarantee. At the same time, the instability of the hand mold base during operation due to welding deformation increases the damage rate of the hand mold base and the breakage rate of the produced gloves. Affect the quality of products and the normal operation of equipment.

Utility model content

In view of the shortcomings of the prior art, the purpose of the present invention is to provide a hand mold seat for installing glove molds with high concentricity between the wheel and the support shaft and high operational stability. The low rate and the breakage rate of the produced gloves ensure the quality of the product and the normal operation of the equipment.

In order to achieve the above objective, the present invention provides the following technical solution: a hand mold base for mounting glove molds, including a mounting part, a support shaft and a wheel, the mounting part includes a bracket and a chuck that are integrally arranged, One end of the support shaft is movably arranged in the chuck, the roulette is sleeved on the other end of the support shaft opposite the chuck, and the support shaft is also sleeved with one end connected to the chuck and the other end connected to the roulette An elastic member, the support shaft is provided with a plurality of obliquely arranged barbs, the plurality of barbs form a fastening part, the barbs include a connecting end fixed on the support shaft and another opposite connecting end of the barbs A free end at one end, the free end is close to the elastic member, the roulette includes a housing, a ferrule arranged in the housing, and a collar sleeved on the ferrule, the ferrule is sleeved on the fastening part On the supporting shaft, the shape and size of the ferrule and the supporting shaft are matched, and the collar is provided with a fastener, and the collar is fixedly connected with the housing through the fastener.

By adopting the above technical solution, when assembling the hand mold holder, the end of the support shaft with the fastening part is plugged and connected in the ferrule of the roulette. The barb is in the shape of an obtuse triangle and the hypotenuse of the barb is attached to the inner wall of the ferrule. Close, one obtuse side of the barb, that is, the connecting end and the support shaft are integrated, and the other obtuse side of the barb has a gap between the support shaft and the support shaft when the support shaft is not inserted into the ferrule. When the support shaft and the ferrule are in a sliding fit , The other obtuse side of the barb opposite to the connecting end is attached to the support shaft, and the free end is located obliquely above the connecting end. The support shaft and the ferrule have a high degree of fit and high concentricity. When the support shaft is fully extended into the slot Then, the collar is sleeved on the ferrule, and fasteners such as bolts or screws or rivets are used to pass through the collar and the housing in turn. The fasteners are threadedly connected with the collar and the housing to make the collar and the card The sleeve, the support shaft and the shell are fixedly connected. The concentricity between the wheel and the support shaft is high and the operation stability is high. The damage rate of the hand mold base and the damage rate of the produced gloves are low, ensuring the quality of the product and the equipment. Normal operation.

The utility model has the following advantages: high concentricity between the wheel and the supporting shaft and high operational stability, the damage rate of the hand mold base and the damage rate of the produced gloves are low, and the quality of the product and the normal operation of the equipment are guaranteed .
