The top of the frame is provided with a feeding roller, on which the composite adhesive film body is wound. A third motor is fixed to the bottom of one side of the frame, and the output end of the third motor is connected to a threaded screw. This utility model, by installing a conveyor belt, fixed seats, a rotating rod, a second motor, a movable sleeve, a support body, and a substrate, allows the substrate to be transported between two supports. The second motor drives the rotating rod to rotate, and the rotating rod has two opposing threaded surfaces. The movable sleeve has threaded holes inside that match the threaded surfaces, facilitating the movement of the supports closer together or apart, and limiting and fixing substrates of different specifications.

[0004] The inventors discovered in their daily work that when using an adhesive film pasting device to paste adhesive film onto material boards, operators need to manually feed the material boards into the device one by one and ensure that the material boards are centered on the adhesive film pasting device. Because this operation process is very cumbersome and relies heavily on manual operation, it leads to low work efficiency.

[0005] Therefore, it is necessary to provide a new type of EVA film pasting device with automatic feeding capability to solve the above-mentioned technical problems. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figure 1 This utility model provides an automatic feeding EVA film pasting device, comprising: a film pasting device 1, a plurality of material plates 6 on the upper surface of the film pasting device 1, a pasting device body 7 mounted on the upper surface of the film pasting device 1, a film body 5 inside the pasting device body 7, a control device 2 mounted on one side of the film pasting device 1, a feeding structure 3 on the upper surface of the film pasting device 1, and a protective structure 4 on the upper surface of the control device 2.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The feeding structure 3 includes a fixed cylinder 301, which is fixedly connected to the adhesive film pasting device 1. The inner wall of the fixed cylinder 301 has a positioning groove 305, two limiting grooves 307, and a connecting groove 306. The positioning groove 305 and the connecting groove 306 are interconnected. A push block 304 is slidably connected to the inner wall of the fixed cylinder 301. A positioning plate 302 is fixedly connected to the side of the fixed cylinder 301 near the push block 304. A cylinder 303 is fixedly connected to the lower surface of the positioning plate 302. The output end of the cylinder 303 is fixedly connected to the push block 304. The fixed cylinder 301 is further... A fixing block 312 is fixedly connected to one side of the positioning plate 302. A lead screw 316 is rotatably connected to the inner wall of the fixing block 312. A rotating ring 314 is fixedly connected to the upper end of the lead screw 316. A moving block 309 is slidably connected to the inner wall of the limiting groove 307. A connecting block 310 is fixedly connected to the side of the moving block 309 away from the fixing cylinder 301. An adjusting plate 311 is fixedly connected to the side of the two connecting blocks 310 that are close to each other. A positioning block 313 is fixedly connected to the side of the adjusting plate 311 away from the fixing cylinder 301. The positioning block 313 is threadedly connected to the lead screw 316. When personnel need to attach the adhesive film body 5 to the material plate 6, they can first slide multiple material plates 6 into the inner wall of the positioning groove 305, and then activate the cylinder 303 to make the push block 304 drive the material plate 6 into the interior of the adhesive device body 7 for attachment. After the push block 304 resets, the material plate 6 will adhere to the adhesive film attachment device 1 due to gravity. Then, the personnel can restart the cylinder 303 to attach the adhesive film to the material plate 6 again. This allows personnel to quickly attach adhesive film to multiple material plates 6, improving work efficiency. The inner wall of the limiting groove 307 is fixedly connected to the limiting rod 308, and the limiting rod 308 is slidably connected to the moving block 309. The limiting rod 308 can limit the movement block 309, preventing it from shifting during sliding on the inner wall of the limiting groove 307. The inner wall of the rotating ring 314 has several anti-slip grooves 315 evenly distributed on its arc surface. These grooves increase friction between the user's hand and the rotating ring 314, preventing slippage during rotation. The inner wall of the fixed cylinder 301 has several graduated grooves 317 evenly distributed on its surface. These grooves allow users to quickly see the distance the adjusting plate 311 has moved, improving ease of operation. The push block 304 is made of stainless steel with a rectangular cross-section. The stainless steel provides high strength and good wear resistance, preventing deformation during short-term use.

[0033] In the embodiments of this utility model, please refer to Figure 4The protective structure 4 includes an iron plate 41 and two mounting blocks 42. The iron plate 41 is fixedly connected to the control device 2, and the two mounting blocks 42 are fixedly connected to the iron plate 41. A fixing rod 43 is fixedly connected to the side of each mounting block 42 closest to each other. A rotating block 44 is rotatably connected to the end of each fixing rod 43 closest to each other. A protective plate 45 is fixedly connected to the side of each rotating block 44 away from the control device 2. A magnetic plate 46 is fixedly connected to the inner wall of the protective plate 45. This design allows personnel to rotate the protective plate 45 after operating the control device 2, causing the magnetic plate 46 to attract the iron plate 41, thus preventing accidental contact with the control device 2 during operation and improving the safety of the adhesive film pasting device 1. A handle 47, shaped like a "U," is fixedly connected to the side of the protective plate 45 away from the magnetic plate 46. The handle 47 facilitates rotation of the protective plate 45, improving operational convenience.

[0034] The working principle of the automatically feeding EVA film pasting device provided by this utility model is as follows: When a person needs to paste the film body 5 onto the material plate 6, the person first passes one end of the film body 5 through the inside of the pasting device body 7. Then, the person activates the rollers and heating device inside the pasting device body 7. Finally, the person places the material plate 6 inside the pasting device body 7 and uses the rotating rollers and heating device to paste the film body 5 onto the material plate 6. When a person needs to feed the material plate 6 into the inside of the pasting device body 7 for pasting, the person can first slide several material plates 6 into the inner wall of the positioning groove 305. Then, the operator rotates the rotating ring 314. The anti-slip groove 315 on the arc surface of the rotating ring 314 increases the friction between the operator's hand and the rotating ring 314, preventing slippage during rotation. The rotating ring 314 then drives the lead screw 316 to rotate, which in turn moves the positioning block 313 upward. The positioning block 313 moves the adjusting plate 311 upward, which in turn moves the two connecting blocks 310 upward. The connecting blocks 310 then move the moving block 309 upward. The moving block 309 rests on the arc surface of the limiting rod 308. The sliding mechanism involves a limiting rod 308 that limits the movement of the moving block 309, preventing misalignment during sliding within the limiting groove 307 until the distance between the adjusting plate 311 and the adhesive film pasting device 1 equals the thickness of the material plate 6. A graduated groove 317 inside the fixed cylinder 301 allows personnel to quickly and easily observe the distance the adjusting plate 311 has moved, improving operational convenience. Then, by activating the cylinder 303, the output of the cylinder 303 drives the push block 304 towards the adhesive film pasting device body 7. The push block 304 then... The material plate 6 abuts against each other and then moves towards the adhesive film bonding device body 7 until the material plate 6 enters the interior of the adhesive film bonding device body 7. When the output end of the cylinder 303 drives the push block 304 to reset, the bottom material plate 6 will adhere to the adhesive film bonding device 1 due to its own weight. At this time, the personnel can push the material plate 6 into the interior of the adhesive film bonding device body 7 again by repeatedly starting the cylinder 303. The push block 304 is a stainless steel block. The stainless steel block has high strength and good wear resistance, which can prevent the push block 304 from deforming during short-term use.

[0035] In addition, when personnel need to protect the control device 2, they can first use the handle 47 to rotate the protective plate 45. The handle 47 makes it easy for personnel to rotate the protective plate 45, which can improve the ease of operation. Then the protective plate 45 drives the magnetic plate 46 and the two rotating blocks 44 to rotate towards the iron plate 41 until the magnetic plate 46 and the iron plate 41 are attracted to each other.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
