Abstract
Description
Technical Field
[0001] This invention relates to the field of plastic molding technology, and more particularly to a glove servo embossing machine. Background Technology
[0002] Plastic gloves generally refer to hand protection products made of plastic materials such as polyethylene, polyvinyl chloride, or latex. With increasing environmental awareness, the industry is placing greater emphasis on the recycling and reuse of plastic waste, striving to reduce carbon emissions and resource waste in the production process. They are widely used in various situations to protect hands from contamination, injury, or irritation.
[0003] During the production of plastic gloves, patterns are typically embossed on them to improve their recognizability. However, existing embossing equipment suffers from drawbacks. Because the handpiece used to fit the gloves at the workstation is made of a single piece and cannot be adjusted, when embossing gloves of different sizes, the thermoforming area of the glove cannot be fully expanded after being placed on the handpiece. This results in wrinkles in the embossed thermoforming area, hindering subsequent thermoforming operations and failing to meet requirements. Furthermore, substandard embossing leads to a large number of unusable defective products, increasing the pressure and cost of subsequent plastic waste recycling and hindering the achievement of green and efficient production goals. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a glove servo embossing machine.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a glove servo embossing machine, comprising a stepped base and a lifting pressure base installed at the front end of the stepped base, a thermoforming component installed at the middle of the front end of the lifting pressure base, a servo rotating component installed at the upper front end of the stepped base, a plurality of glove supports arranged in a circular array on the outer side of the servo rotating component, tensioning frames slidably arranged on both sides of the glove supports, a threaded column rotatably installed at the end of the glove supports, a threaded sleeve screwed onto the outer surface of the threaded column, an adjusting frame connected between the two sides of the threaded sleeve and the two tensioning frames, the adjusting frame being inclined, the two adjusting frames being symmetrically arranged, and a top component installed on the glove supports.
[0006] Preferably, two guide rods are symmetrically slidably installed at the rear end of the lifting pressure seat. The two ends of the guide rods are fixed to the front end of the step seat. A threaded rod is provided between the two guide rods. The lifting pressure seat is screwed to the outer surface of the threaded rod. A first servo motor is installed at the upper end of the threaded rod. The first servo motor is fixed on the step seat.
[0007] Preferably, one end of the adjusting frame is rotatably mounted with an extension ear, the end of which is fixed to the threaded sleeve; the other end of the adjusting frame is rotatably mounted with a connecting ear, the end of which is fixed to the tensioning frame; a rotating ring is coaxially embedded on the outer surface of the threaded column, the rotating ring being located behind the threaded sleeve; square guide blocks extend from both sides of the glove holder near the edge, and the tensioning frame is slidably mounted on the surface of the square guide blocks.
[0008] Preferably, the servo rotating component includes a motor frame fixedly installed at the upper front of the stepped seat, a connecting shaft rotatably mounted through the upper end of the motor frame, a station turntable coaxially fixedly mounted at the upper end of the connecting shaft, a second servo motor fixedly mounted inside the motor frame, the output end of the second servo motor being fixed to the lower end of the connecting shaft, a fixing frame fixedly mounted at the lower edge of the glove support, one end of the fixing frame being fixed to the station turntable, and the end of the threaded column being rotatably connected to the station turntable.
[0009] Preferably, the top member includes a through cavity extending through the upper end of the glove holder, a top impression seat is fitted inside the through cavity, a support frame is elastically mounted at the other end of the fixing frame, the top impression seat is embedded in one end of the support frame, an extension frame extends from the side of the fixing frame, a gear is rotatably mounted at the end of the extension frame, a first toothed plate is embedded at the other end of the support frame, the first toothed plate meshes with the front part of the gear, a second toothed plate meshes with the rear part of the gear, the second toothed plate is elastically connected to the extension frame, and a corner bracket is fixedly mounted near the edge of the front end of the lifting pressure seat.
[0010] Preferably, the support frame has a cavity through the middle, and the other end of the fixed frame extends into a protruding seat. The protruding seat is slidably installed inside the cavity, and guide rails extend from both sides of the cavity, with the guide rails slidably passing through both sides of the protruding seat.
[0011] Preferably, a first reset spring is fixedly installed on the inner bottom surface of the receiving cavity. The end of the first reset spring is fixed to the lower end of the extension seat. An L-shaped frame extends from the rear end of the extension frame near the edge. The extension frame and the L-shaped frame are integrally formed. Two guide posts are symmetrically fixedly installed on the upper end of the L-shaped frame. Push blocks are slidably installed on the outer surface of the two guide posts. The end of the push block is fixed to the second toothed plate.
[0012] Preferably, a second return spring is wound around the outside of the guide post, the lower end of the second return spring is fixed to the L-shaped frame, the upper end of the second return spring is fixed to the lower end of the push block, and a positioning cap is coaxially embedded at the end of the guide post, the positioning cap being attached to the upper end of the push block.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By rotating the threaded column, the threaded sleeve can be moved, which in turn drives the two adjusting frames to move, thereby simultaneously pushing the two tensioning frames. This allows the two tensioning frames to slide on the square guide block and move outward synchronously, thus adjusting the distance between the two tensioning frames. This ensures that when plastic gloves of different sizes are placed on the glove holder and tensioning frames, the thermoforming area of the plastic gloves can be fully expanded, ensuring that subsequent embossing operations can proceed normally and meet the embossing requirements.
[0014] 2. When the lifting pressure seat moves the thermoforming component downwards for imprinting, the corner frame moves downwards synchronously with the lifting pressure seat to push the second toothed plate, allowing the second toothed plate to slide down on the guide post. This drives the gear to rotate, which in turn drives the first toothed plate meshing with the gear to move upwards, thereby moving the imprinting seat on the support frame upwards. At this time, the extension seat slides in the receiving cavity to guide the upward-moving imprinting seat. The upward-moving imprinting seat supports the thermoforming area of the plastic glove from below, thereby increasing the imprinting force between the thermoforming area of the plastic glove and the thermoforming component, allowing the surface shape to be clearly formed on the plastic glove, thus ensuring product quality.

[0018] like Figures 1-6 The glove servo embossing machine shown includes a stepped base 1 and a lifting pressure base 35 installed at the front end of the stepped base 1. A thermoforming component 5 is installed at the middle of the front end of the lifting pressure base 35. The lifting pressure base 35 moves down, causing the thermoforming component 5 to move down and contact the plastic glove, so that the pattern is embossed on the plastic glove through the thermoforming component 5. The lower end of the thermoforming component 5 is a molding die, which is equipped with a heating tube and a thermocouple (temperature sensor). The plastic part in contact with the molding die is melted by heating. Since the above thermoforming operation is existing technology and has been widely used, it is not described in detail here. A servo rotating component is installed at the front of the upper end of the stepped seat 1. Multiple glove supports 17 are arranged in a ring array on the outer side of the servo rotating component. Tensioning frames 19 are slidably arranged on both sides of the glove support 17. A threaded column 24 is rotatably installed at the end of the glove support 17. The tensioning frame 19 plays the role of fully unfolding the plastic glove. A threaded sleeve 23 is screwed onto the outer surface of the threaded column 24. The threaded column 24 and the threaded sleeve 23 play the role of driving the adjustment frame 22 to move. The two sides of the threaded sleeve 23 are connected to the two tensioning frames 19. The adjustment frame 22 is inclined and the two adjustment frames 22 are symmetrically arranged. The adjustment frame 22 can drive the two tensioning frames 19 to move synchronously for adjustment to accommodate plastic gloves of different sizes. A top component is installed on the glove support 17.
[0019] Two guide rods 36 are symmetrically slidably installed at the rear end of the lifting pressure seat 35. The two ends of the guide rods 36 are fixed to the front end of the step seat 1. The guide rods 36 guide the lifting pressure seat 35. A threaded rod 37 is provided between the two guide rods 36.

A servo motor 6 is installed at the upper end of the threaded rod 37. The servo motor 6 is fixed on the step seat 1. The servo motor 6 drives the threaded rod 37 to rotate.
[0020] An extension lug 26 is rotatably mounted on one end of the adjusting frame 22. The end of the extension lug 26 is fixed to the threaded sleeve 23. The extension lug 26 facilitates connection with the adjusting frame 22. A connecting lug 21 is rotatably mounted on the other end of the adjusting frame 22. The end of the connecting lug 21 is fixed to the tensioning frame 19. The connecting lug 21 facilitates connection with the adjusting frame 22. A rotating ring 25 is coaxially embedded on the outer surface of the threaded post 24. The rotating ring 25 is located behind the threaded sleeve 23. The rotating ring 25 facilitates rotation of the threaded post 24. Square guide blocks 20 extend from both sides of the glove support 17 near the edge. The tensioning frame 19 is slidably mounted on the surface of the square guide blocks 20. The square guide blocks 20 guide the tensioning frame 19.
[0021] The servo rotating component includes a motor frame 2 fixedly installed at the upper front of the stepped seat 1. A connecting shaft 16 is rotatably mounted through the upper end of the motor frame 2. The motor frame 2 serves to support the connecting shaft 16 and the second servo motor 15. A station turntable 3 is coaxially fixedly installed at the upper end of the connecting shaft 16. The second servo motor 15 is fixedly installed inside the motor frame 2. The output end of the second servo motor 15 is fixed to the lower end of the connecting shaft 16. A fixing frame 13 is fixedly installed at the lower edge of the glove support 17. When the second servo motor 15 works, it drives the station turntable 3 on the connecting shaft 16 to rotate, so as to rotate the station with the plastic glove to the bottom of the thermoforming component 5. One end of the fixing frame 13 is fixed to the station turntable 3. The fixing frame 13 serves to fix the glove support 17 and the station turntable 3 together. The end of the threaded column 24 is rotatably connected to the station turntable 3, which can strengthen the connection of the threaded column 24.
[0022] The top component includes a through cavity 18 extending through the upper end of the glove holder 17. A top impression seat 7 is fitted inside the through cavity 18, which serves to accommodate the top impression seat 7. A support frame 8 is elastically mounted at the other end of the fixed frame 13. The top impression seat 7 is embedded in one end of the support frame 8. An extension frame 14 extends from the side of the fixed frame 13. A gear 33 is rotatably mounted at the end of the extension frame 14, which serves to support the gear 33. A first toothed plate 27 is embedded at the other end of the support frame 8. The first toothed plate 27 meshes with the front part of the gear 33. A second toothed plate 28 meshes with the rear part of the gear 33. The gear 33 serves to make the first toothed plate 27 and the second toothed plate 28 move in opposite directions. The second toothed plate 28 is elastically connected to the extension frame 14. An angle bracket 4 is fixedly mounted near the edge of the front end of the lifting pressure seat 35, which serves to push the second toothed plate 28.
[0023] The support frame 8 has a cavity 9 through the middle, and the other end of the fixed frame 13 extends to the extension seat 12. The cavity 9 and the extension seat 12 serve to guide the support frame 8. The extension seat 12 is slidably installed inside the cavity 9. Guide slides 10 extend from both sides of the cavity 9. The guide slides 10 slide through both sides of the extension seat 12 and serve to prevent the support frame 8 from separating from the extension seat 12.
[0024] A first return spring 11 is fixedly installed on the bottom surface of the inner cavity 9. The end of the first return spring 11 is fixed to the lower end of the extension seat 12. The first return spring 11 can push the support frame 8 to reset the moved support frame 8. An L-shaped frame 29 extends from the rear end of the extension frame 14 near the edge. The extension frame 14 and the L-shaped frame 29 are integrally formed. Two guide posts 31 are symmetrically fixed on the upper end of the L-shaped frame 29. The L-shaped frame 29 serves to support the guide posts 31. Push blocks 34 are slidably installed on the outer surface of the two guide posts 31. The end of the push block 34 is fixed to the second toothed plate 28. The guide posts 31 and push blocks 34 serve to guide the second toothed plate 28.
[0025] A second return spring 30 is wound around the outside of the guide post 31. The lower end of the second return spring 30 is fixed to the L-shaped frame 29. The second return spring 30 serves to reset the second toothed plate 28 after it has been moved. The upper end of the second return spring 30 is fixed to the lower end of the push block 34. A positioning cap 32 is coaxially embedded at the end of the guide post 31. The positioning cap 32 serves to limit the reset position of the second toothed plate 28. The positioning cap 32 is attached to the upper end of the push block 34.
[0026] In use, first rotate the threaded post 24 according to the size of the plastic glove, causing the threaded sleeve 23 to move, which in turn drives the two adjusting brackets 22 to move, simultaneously pushing the two tensioning brackets 19 so that they can slide on the square guide block 20 and move outward synchronously. This adjusts the distance between the two tensioning brackets 19 to fit the size of the plastic glove. Then, put the plastic glove on the tensioning bracket 19 and glove support 17, allowing the thermoforming area of the plastic glove to be fully expanded. Then, the second servo motor 15 drives the station turntable 3 on the connecting shaft 16 to rotate, moving the station with the plastic glove under it to below the thermoforming component 5. Then, the first servo motor 6 drives the threaded rod 37 to rotate, causing the lifting pressure seat 35 screwed on the threaded rod 37 to move. The device can move downwards, thereby causing the thermoforming component 5 to move downwards and contact the plastic glove, so as to imprint the pattern onto the plastic glove. During this process, the corner frame 4 will move downwards synchronously with the lifting pressure seat 35 to push the second toothed plate 28, so that the second toothed plate 28 can slide on the guide post 31 and move downwards, thereby driving the gear 33 to rotate, thereby driving the first toothed plate 27 meshing on the gear 33 to move upwards, thereby driving the imprint seat 7 on the support frame 8 to move upwards. At this time, the extension seat 12 slides in the receiving cavity 9 to guide the upward imprint seat 7, so that the upward imprint seat 7 supports the thermoforming area of the plastic glove from below, thereby increasing the imprinting force between the thermoforming area of the plastic glove and the thermoforming component 5, so that the surface shape can be clearly formed on the plastic glove, thereby ensuring product quality.
