[0025] The present utility model will be further described below with reference to the embodiments shown in the drawings.

[0026] As Figures 1-4 shown, it is the structural schematic diagram of the automatic protective film pasting structure of the present utility model, which is used to paste a protective film on the surface of a product, improving the pasting efficiency and accuracy while saving labor costs. This structure includes a bottom plate 1, a clamping assembly and a pressing assembly.

[0027] The bottom plate 1 is fixed on the packaging machine table by means of screw fastening. The clamping assembly is fixed on the top of the bottom plate 1 and is used to clamp the product to be film-sealed and drive the product to rotate. The pressing assembly is erected above the clamping assembly. During the film-sealing process, the pressing assembly descends and abuts against the surface of the protective film to ensure that the protective film perfectly adheres to the surface of the product, improving the film-sealing effect.

[0028] The clamping assembly includes a first vertical plate 2, a driving motor 3, a main rotating head 4, a first abutting plate 5, a first inserting block 6, a connecting plate 7, a photoelectric sensor 8, an induction piece 9, a limiting groove 10, an adjusting plate 11, a second vertical plate 12, a carrier plate 13, an adjusting groove 14, a fixing hole 15, a slider 16, a slide rail 17, a sliding plate 18, a fixing plate 19, a pushing cylinder 20, a sleeve rod 21, a secondary rotating head 22, a second abutting plate 23 and a second inserting block 24. The first vertical plate 2 is vertically fixed on the top of the bottom plate 1. The housing of the driving motor 3 is fixed on the first vertical plate 2. The driving shaft of the driving motor 3 penetrates through the first vertical plate 2 and is connected to the main rotating head 4, and the main rotating head 4 is driven to rotate by the driving motor 3.

[0029] The connecting plate 7 is fixed on one side of the first vertical plate 2. The photoelectric sensor 8 is fixed on the side of the connecting plate 7 close to the main rotating head 4. The induction piece 9 is fixed on the outer wall of the main rotating head 4 and cooperates with the photoelectric sensor 8. When the driving motor 3 drives the main rotating head 4 to rotate, the induction piece 9 will be driven to rotate synchronously. Through the cooperation with the photoelectric sensor 8, it is ensured that the main rotating head 4 rotates one circle (i.e., 360°) each time, improving the precision of film sealing and avoiding excessive fitting of the protective film on the product surface, resulting in waste of the protective film.

[0030] The limiting groove 10 is opened on the top of the bottom plate 1 and is arranged opposite to the first vertical plate 2. The adjusting plate 11 is arranged in the limiting groove 10. The width of the adjusting plate 11 is equal to the width of the limiting groove 10, and the length of the adjusting plate 11 is less than the length of the limiting groove 10, ensuring that the adjusting plate 11 has space to move in the limiting groove 10, so as to meet the clamping of products with different length dimensions.

[0031] Since the width of the adjusting plate 11 is equal to the width of the limiting groove 10, when the adjusting plate 11 is adjusted, the limiting groove 10 will play a role in limiting the adjusting plate 11, thereby ensuring that the adjusting plate 11 does not shift during movement, ensuring that the secondary rotating head 22 and the main rotating head 4 are still in a coaxial state, and avoiding twisting the product during the process of clamping and rotating the product.

[0032] The adjusting groove 14 is opened at the bottom of the limiting groove 10 and penetrates through the bottom plate 1. The adjusting groove 14 is in the shape of a rounded rectangle. The fixing hole 15 penetrates through the adjusting plate 11 and cooperates with the adjusting groove 14. After the adjusting plate 11 is moved to an appropriate position, a fastening bolt is passed through the fixing hole 15 and the adjusting groove 14, and a nut is supplemented on the other side to complete the fixing of the adjusting plate 11.

[0033] The second vertical plate 12 is vertically fixed on the top of the adjusting plate 11. The carrier plate 13 is fixed on the top of the second vertical plate 12. The slider 16 is fixed on the top of the carrier plate 13. The slide rail 17 is slidably connected to the slider 16. The sliding plate 18 is fixed on the top of the slide rail 17. When the sliding plate 18 moves, it will drive the slide rail 17 to move synchronously along the slider 16. Under the cooperation of the slide rail 17 and the slider 16, the stability of the sliding process of the sliding plate 18 is improved.

[0034] The fixed plate 19 is fixed on the top of the carrier plate 13. The cylinder block of the pushing cylinder 20 is fixed on the fixed plate 19. The piston rod of the pushing cylinder 20 passes through the fixed plate 19 and is connected to the sliding plate 18, and the sliding plate 18 is driven to move by the pushing cylinder 20. The sleeve rod 21 is fixed on the side of the sliding plate 18 away from the fixed plate 19. The secondary rotating head 22 is sleeved on the sleeve rod 21 through a bearing, ensuring that the secondary rotating head 22 can rotate relative to the sleeve rod 21.

[0035] The first abutting plate 5 is fixed inside the main rotating head 4, and the second abutting plate 23 is fixed inside the secondary rotating head 22. The first inserting block 6 is fixed inside the first abutting plate 5, and the cross-sectional area of the first inserting block 6 is smaller than that of the first abutting plate 5; the second inserting block 24 is fixed inside the second abutting plate 23, and the cross-sectional area of the second inserting block 24 is smaller than that of the second abutting plate 23.

[0036] The shapes of the first inserting block 6 and the second inserting block 24 are not fixed and can be appropriately adjusted according to the shapes of the sockets on both sides of the product. The first abutting plate 5 and the second abutting plate 23 are used to abut against both sides of the product.

[0037] During actual film sealing, first, the position of the adjusting plate 11 is appropriately adjusted according to the length of the product. Then, one side of the product is inserted into the first inserting block 6. The pushing cylinder 20 pushes the sliding plate 18 to move toward the side close to the product until the second inserting block 24 is inserted into the other side of the product, thus completing the clamping work of the product. When the driving motor 3 drives the main rotating head 4 to rotate, the product and the secondary rotating head 22 are driven to rotate synchronously. With the cooperation of the upper pressing assembly, the film sealing of the product surface is completed.

[0038] The pressing assembly is erected above the clamping assembly. During the film sealing process, the pressing assembly descends and abuts against the surface of the protective film, ensuring that the protective film perfectly adheres to the surface of the product and improving the film sealing effect. The pressing assembly includes a support frame 25, a downward pressing cylinder 26, a pressing table 27, a first guide sleeve 28, a first guide post 29, a first anti-disengagement plate 30, a second guide sleeve 31, a second guide post 32, a second anti-disengagement plate 33, a spring 34, a pressing plate 35, a pressing rod 36, and a pressing cylinder 37. The support frame 25 is fixed on the top of the bottom plate 1. The cylinder block of the downward pressing cylinder 26 is fixed on the support frame 25. The guide rod of the downward pressing cylinder 26 passes through the support frame 25 and is connected to the pressing table 27, and the pressing table 27 is driven to descend by the downward pressing cylinder 26 to approach the product to be film-sealed.

[0039] The first guide sleeve 28 is embedded in the support frame 25. The first guide post 29 passes through the first guide sleeve 28, and the first guide post 29 is fixed to the top of the pressing table 27. When the downward pressing air cylinder 26 drives the pressing table 27 to descend, it will drive the first guide post 29 to descend synchronously along the first guide sleeve 28. By providing the mutually cooperating first guide post 29 and first guide sleeve 28, it plays a guiding role in the descent of the pressing table 27, improves the accuracy of the descending position of the pressing table 27, and avoids the deviation of the pressing table 27 during descent.

[0040] The first anti - detachment plate 30 is fixed to the top of the first guide post 29, and the diameter of the first anti - detachment plate 30 is larger than that of the first guide post 29. By providing the first anti - detachment plate 30, it avoids the first guide post 29 slipping out of the first guide sleeve 28 during descent.

[0041] The second guide sleeve 31 is embedded in the pressing table 27. The second guide post 32 passes through the second guide sleeve 31, and a pressing plate 35 is fixed to the bottom of the second guide post 32. The second anti - detachment plate 33 is fixed to the top of the second guide post 32 and the diameter of the second anti - detachment plate 33 is larger than that of the second guide post 32. By providing the second anti - detachment plate 33, it avoids the second guide post 32 slipping out of the second guide sleeve 31.

[0042] The spring 34 is sleeved on the second guide post 32, and the spring 34 abuts between the pressing table 27 and the pressing plate 35. By providing the spring 34, it ensures that the pressing plate 35 is in a floating state. The pressing rod 36 is fixed between the pressing plates 35, and the pressing cylinder 37 is sleeved on the pressing rod 36 through a bearing, so the pressing cylinder 37 can rotate freely relative to the pressing rod 36.

[0043] The material of the pressing cylinder 37 is rubber, which avoids damaging the product and leaving indentations on the surface of the protective film when extruding the protective film.

[0044] By providing the spring 34, it ensures that the pressing cylinder 37 is in an elastic state. The pressing cylinder 37 abuts against the protective film, which can tightly attach the protective film to the outer surface of the product, improve the effect after film sealing, and avoid situations such as wrinkles or bubbles; at the same time, it is suitable for more types of products, such as rectangular products, cylindrical products, and elliptical products can all complete film sealing.

[0045] The film sealing process of the automatic protective film pasting structure of the present utility model is as follows:

[0046] First, adjust the position of the adjusting plate 11 appropriately according to the length of the product, then insert one side of the product into the first insert block 6, and the pushing air cylinder 20 pushes the push plate to move towards the side close to the product until the second insert block 24 is inserted into the other side of the product, thus completing the clamping work of the product;

[0047] The pressing cylinder 26 drives the pressing table 27 to descend until the pressing cylinder 37 abuts against the protective film on the surface of the product (a protective film unwinding roller is arranged on the other side of this structure, and a protective film roll is sleeved on the unwinding roller. During the rotation of the main rotating head 4, the protective film is drawn). When the driving motor 3 drives the main rotating head 4 to rotate, the product and the auxiliary rotating head 22 are driven to rotate synchronously. Under the elastic pressing action of the pressing cylinder 37, the protective film is pressed on the surface of the product, and finally the protective film can be cut off by the operator or by laser.

[0048] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention.
