Description

Technical Field

[0001] This utility model relates to the field of special glove processing technology, specifically a multi-layer pressing device for special gloves. Background Technology

[0002] Specialty gloves are gloves specifically designed for particular working environments and tasks, providing specialized protection. They are typically used in high-risk or extreme environments to protect hands from physical, chemical, or biological hazards; these include electrical insulating gloves, chemical-resistant gloves, welding gloves, and cut-resistant gloves. Due to their multi-layered nature, specialty gloves require hot-pressing during manufacturing. This involves bonding multiple layers of materials under high temperature and pressure, fusing them together. Some gloves may require cold pressing after hot pressing to release stress and ensure a smooth finish.

[0003] Currently, existing glove hot pressing generally uses a hot press / heat sealing machine, but there are still some shortcomings in actual use, as follows:

[0004] 1. Because the temperature of the hot press is relatively high during the pressing process, if the pressing force is too large or the time is too long, some materials are prone to being damaged or excessively deformed, which is not conducive to the quality assurance of the product.

[0005] 2. During the hot pressing process, some materials may produce smoke or odors due to the increase in temperature. These fumes are usually pungent and may even contain toxic substances. Long-term exposure to these fumes can affect the physical and mental health of workers. Utility Model Content

[0010] The bottom of the positioning plate is also provided with a hot press plate located above the heating mold.

[0011] As a preferred embodiment of the multi-layer pressing device for special gloves described in this utility model, the top of the air collecting plate is also connected to at least one connecting air nozzle, and one side of the mounting plate has a clearance hole corresponding to the connecting air nozzle.

[0013] As a preferred embodiment of the multi-layer pressing device for special gloves described in this utility model, the elastic connecting rod includes a guide rod that is vertically fixed to the four corners of the top of the positioning plate and slidably passed through the upper end of the top plate, a limiting block fixed to the top of the guide rod, and a spring sleeved on the upper end of the guide rod.

[0014] The upper end of the spring abuts against the limiting block and the lower end abuts against the top of the top plate.

[0015] As a preferred embodiment of the multi-layer pressing device for special gloves described in this utility model, the pressure sensing component includes a plurality of first electric push rods vertically arranged on the periphery of the top plate, and a pressure sensor arranged at the bottom output shaft end of the first electric push rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (i) This special glove multi-layer pressing device, when hot pressing the glove, the hydraulic cylinder will drive the mounting plate and the air collection plate to descend synchronously, so that the air collection plate, with the cooperation of the mounting plate, forms a closed cover on the work tank area, so that the smoke and odor generated during the hot pressing process are restricted to the area.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Figures 1-3 The diagram shown is a complete structural schematic of a multi-layer pressing device for special gloves according to this utility model. Please refer to [link / reference]. Figures 1-3 This embodiment of a special glove multi-layer pressing device includes a hot press body 100. The upper part of the processing table of the hot press body 100 has a groove 110 and a heating mold 200 disposed at the bottom inner side of the groove 110. A hydraulic cylinder 300 is disposed on the upper part of the frame of the hot press body 100, and a mounting plate 400 is installed at the bottom output end of the hydraulic cylinder 300. Hollow air-collecting plates 500 are vertically mounted around the bottom of the mounting plate 400, and the four air-collecting plates 500 are adjacent and interconnected. Several air-suction holes 5001 communicating with the inner cavity of the air-collecting plates 500 are opened on the inner side of the mounting plate 400. A second electric actuator 700 is positioned at the center of the 0; a hot press auxiliary seat 600 is located directly below the mounting plate 400 and inside the gas collection enclosure 500. The hot press auxiliary seat 600 includes a top plate 610 fixedly connected to the bottom output shaft end of the second electric actuator 700, a positioning plate 620 located directly below the top plate 610, elastic connecting rods 630 connecting the four corners of the positioning plate 620 and the top plate 610, a vibrator 640 set on the positioning plate 620, and multiple pressure sensing components 650 set on the top plate 610; wherein, a hot press plate 210 located above the heating mold 200 is also provided at the bottom of the positioning plate 620.

[0028] The top of the gas collection enclosure 500 is also connected to at least one connecting nozzle 510, and one side of the mounting plate 400 has a clearance hole corresponding to the connecting nozzle 510. It is understood that the connecting nozzle 510 is connected to the air pump via an external pipeline. It should be noted that a waste gas purification device, such as a UV photo-oxidation purifier or activated carbon filter box, should be installed at the gas collection end; specific measures will depend on the actual situation. The length and width dimensions of the gas collection enclosure 500 match the length and width dimensions of the trough 110 and are vertically aligned. A sealing ring 800 is also provided around the bottom of the gas collection enclosure 500. The sealing ring 800 effectively reduces the edge contact gap of the gas collection enclosure 500 after it is pressed against the trough 110. It should be noted that the gas collection enclosure 500 is not easily completely sealed after being closed with the trough 110 lid; otherwise, regional negative pressure will form during the suction process. Therefore, the main purpose of the sealing ring 800 is to cover some large gaps to prevent smoke from spreading and overflowing. Specifically, in this embodiment, during the hot pressing of the gloves, the hydraulic cylinder 300 drives the mounting plate 400 and the air collection plate 500 to descend synchronously. With the cooperation of the mounting plate 400, the air collection plate 500 forms a enclosure around the work tank 110 area, preventing the smoke and odor generated during the hot pressing process from accumulating in that area. Subsequently, the air collection plate 500 is sucked up through the air pump pipeline, and the smoke drifting inside is quickly removed through the air intake 5001. After the hot pressing is completed, the plate rises and detaches, without delaying the normal handling of workpieces and ensuring the physical and mental health of the workers.

[0029] The elastic connecting rod 630 includes guide rods 631 vertically fixed to the four corners of the top of the positioning plate 620 and slidably passing through the upper end of the top plate 610, limiting blocks 630 fixed to the top of the guide rods 631, and springs 633 sleeved on the upper end of the guide rods 631; wherein, the upper end of the spring 633 abuts against the limiting block 630 and the lower end abuts against the top of the top plate 610. The pressure sensing assembly 650 includes a plurality of first electric push rods 651 vertically arranged around the periphery of the top plate 610, and a pressure sensor 652 arranged at the bottom output shaft end of the first electric push rods 651. A positioning frame 410 is also fixed to the top of the top plate 610, and the bottom output shaft end of the hydraulic cylinder 300 is fixedly connected to the top of the positioning frame 410. This prevents the output shaft of the hydraulic cylinder 300 from interfering with the second electric push rod 700. Specifically, in this embodiment, during operation, the hydraulic cylinder 300 drives the mounting plate 400 and the hot press auxiliary seat 600 to descend synchronously. After the air collecting plate 500 and the work trough 110 are closed and connected, the second electric push rod 700 will drive the top plate 610 to descend. When the positioning plate 620 and the bottom hot press plate 210 contact the material and form a reverse thrust, the pressure gauge 652 will detect the pressure value in time. When the sum of the pressure values ​​of multiple pressure gauges 652 reaches a certain value, the pressure will be measured. After the set average value is reached, the first electric actuator 651 will immediately retract the pressure sensor 652 and simultaneously stop the second electric actuator 700. At this time, with the cooperation of the vibrator 640 and the elastic connecting rod 630, a high-frequency micro-vibration will be formed between the hot press plate 210 and the material, so that the material layers form a high-frequency full hot press contact and release cycle in a short time. On the one hand, it can prevent the material from being damaged or deformed due to excessive pressing force and time, and on the other hand, it can avoid the pressing effect from being reduced due to insufficient pressure, so that the product quality can be effectively guaranteed.
