Description

Technical Field

[0001] The utility model relates to the technical field of PVC glove production equipment, in particular to a PVC glove demoulding equipment. Background Art

[0002] Polyvinyl chloride (PVC) gloves are a kind of protective equipment widely used in medical, food processing, cleaning services and chemical industries. This type of gloves has good chemical resistance, puncture resistance and high cost-effectiveness, making it the first choice for many application scenarios. The production process of PVC gloves mainly includes: mixing formula preparation, hand mold cleaning and pretreatment, impregnation, curing and drying, and finally demoulding and packaging. In the production process, the quality and design of the hand mold directly affect the quality and production efficiency of the final product.

[0003] Deficiencies of existing technology:

[0004] Traditional demoulding is usually divided into two stages: semi-demolding and full demoulding. In the semi-demolding stage, the goal is to slightly separate the curled edge of the PVC glove from the hand mold and hang it on the mold. The success of this step is crucial because it directly affects the smooth progress of full demoulding. However, due to the viscosity of the glove material and the space limitation inside the mold, it is often difficult for the demoulding equipment to smoothly enter the inside of the glove for operation. In addition, the gloves are susceptible to physical damage during the semi-demolding process, such as excessive stretching or tearing. These problems are often caused by improper contact between the equipment and the gloves. These challenges not only reduce production efficiency, but also increase the scrap rate, which has a negative impact on production costs and product quality. To address these problems, it is necessary to develop new demoulding technologies and equipment to improve the success rate of semi-demolding and overall production efficiency. Utility Model Content

[0035] Please refer to Figure 1-7 As shown, a technical solution of a PVC glove demolding device provided by the present utility model: a PVC glove demolding device includes a conveyor line 1, a glove mold 2 is arranged on the conveyor line 1, an expanding mechanism 3 for facilitating demolding is arranged inside the glove mold 2, and a demolding mechanism 4 is arranged on the side of the conveyor line 1;

[0036] The expanding mechanism 3 includes a number of movable openings 301, a supporting part 302, and a support plate 306. The movable openings 301 are formed on the side wall of the glove mold 2, the supporting part 302 is arranged inside the glove mold 2, a rocker 303 is rotatably connected to the inside of the supporting part 302, pressing parts 304 and expanding parts 305 are respectively arranged at both ends of the rocker 303, the pressing parts 304 and the expanding parts 305 are respectively arranged in different movable openings 301, the support plate 306 is arranged inside the glove mold 2, and a spring 307 is arranged between the support plate 306 and the pressing part 304. When the PVC glove is conveyed to the demolding mechanism 4, the demolding mechanism 4 will press the pressing parts 304 located on both sides of the glove mold 2. At this time, the expanding parts 305 will expand the curled part of the PVC glove. Then, the demolding mechanism 4 extends into the gap between the glove mold 2 and the PVC glove, and semi-demolding operation can be carried out to improve the demolding efficiency. When the demolding mechanism 4 releases the pressing on the pressing parts 304, it will reset under the action of the spring 307 for the next use.

[0037] The demolding mechanism 4 includes a frame 401, a cylinder 404, and a second slide bar 405. The frame 401 is arranged on the side of the conveyor line 1. Inside the frame 401, several groups of first slide bars 402 are arranged. A carrier frame 403 is slidably arranged on the first slide bars 402. The cylinder 404 is arranged on the side wall of the frame 401, and the output end of the cylinder 404 is connected to the carrier frame 403. The second slide bar 405 is arranged inside the carrier frame 403. A group of sliders 406 are arranged on the second slide bar 405. An electromagnet 407 is arranged inside the sliders 406. Clamping rods 408 are arranged on the upper end surfaces of the sliders 406. Insertion plates 409 are arranged on the clamping surfaces of the clamping rods 408. During the demolding process, the entire demolding mechanism 4 will be pre - established on both sides of the pressing part 304. By controlling the electromagnet 407 to generate different magnetic poles, the pressing part 304 is pressed. Then, by the retraction of the cylinder 404, the insertion plates 409 enter the inside of the PVC glove. As the cylinder 404 continues to move, the curled part of the PVC glove will be turned over and pulled outwards to complete the semi - demolding process. After the semi - demolding is completed, the electromagnet 407 is controlled to generate the same magnetic poles. At this time, the two insertion plates 409 are separated. Finally, under the action of the cylinder 404, the carrier frame 403 is pushed back to the initial position to await the next operation.

[0038] The end of the insertion plate 409 is arc - shaped. In this design, the design of the arc - shaped end helps to reduce the wear of the insertion plate 409 on the glove mold 2, extend the service life of the glove mold 2, and at the same time, it can also reduce the damage of the PVC glove during the production process and improve the demolding efficiency of the PVC glove.

[0039] An air guiding mechanism 5 is also arranged inside the carrier frame 403. The air guiding mechanism 5 includes an air blowing port 501 and a corrugated pipe 502. The air blowing port 501 is opened on the lower end surface of the carrier frame 403, and the corrugated pipe 502 is sleeved on the air blowing port 501. In the specific implementation process, the end of the corrugated pipe 502 is connected to an external blower. When the curled part of the PVC glove is pulled to the air blowing port 501, the blower sweeps it, so that the curled part is separated from the insertion plate 409, so as to be conveyed by the conveyor line 1 to the next production line for full demolding operation.

[0040] Rubber buffer parts 6 are arranged on the inner side of the carrier frame 403 and the sides of the sliders 406. This design can ensure the stability and safety of the device under high - frequency operation conditions, protect the sliders 406 and the carrier frame 403 from damage, and at the same time, reduce the noise caused by impact and improve the operation environment quality of the equipment.

[0041] The working principle of the present utility model is as follows:

[0042] When the PVC glove demoulding device of the present embodiment is in use, the conveyor line 1 will convey the glove mold 2 with the PVC glove. When it reaches the predetermined position, the opened clamping rod 408 will be pushed to the two sides of the pressing part 304 of the glove mold 2 by the cylinder 404. During the semi-demolding, the electromagnet 407 generates suction and presses the pressing part 304, and the curling part of the PVC glove is stretched open. With the advancement of the cylinder 404, the insert plate 409 will extend into the inside of the PVC glove and perform the semi-demolding operation. When the curling part of the PVC glove is pulled to the blowing port 501, the fan sweeps it so that the curling part is separated from the insert plate 409. At this time, the semi-demolding work of the entire PVC glove is completed.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
