Specific embodiments
[0022] The following further describes the utility model with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model and cannot be used to limit the protection scope of the utility model.
[0023] The utility model provides a slitting device for producing a protective film as Figures 1-5 shown, including a base 1. A support plate 5 for conveying the protective film body 3 is provided at the top of the base 1. A slitting groove 20 for slitting the protective film is opened at the top of the support plate 5. A first pressing plate 8 and a second pressing plate 17 for fixing the protective film body 3 are provided on both sides of the slitting groove 20. A cutting blade 6 that can reciprocally slide along the length direction of the slitting groove 20 is provided at the top of the slitting groove 20. Sliders 12 that can reciprocally slide along the length direction thereof are provided at both ends of the support plate 5. A vacuum chuck 16 for adsorbing the protective film body 3 and moving the protective film body 3 to a specified distance is provided on one side of the slider 12. The first pressing plate 8 and the second pressing plate 17 are respectively provided on both sides of the slitting groove 20 to fix the protective film body 3, prevent the protective film from shifting or sliding during slitting, thereby ensuring the accuracy and stability of slitting, reducing errors caused by material vibration during cutting, and further improving the cutting accuracy.
[0024] The base 1 is installed with a slitting bracket 2 located at the top of the slitting groove 20. Inside the slitting bracket 2, there is a screw rod 21 that can rotate actively. The top end of the cutting blade 6 is threadedly connected to the screw rod 21. The cutting blade 6 can be telescoped longitudinally. The cooperation between the two pressing plates and the cutting blade 6 can achieve continuous and stable cutting operations, improve production efficiency and output. By rotating the screw rod 21, the reciprocating sliding of the cutting blade 6 can be realized, meeting the slitting requirement of the protective film body 3.
[0025] Both ends of the slitting bracket 2 are provided with positioning brackets 7. The first pressing plate 8 is located at the bottom end of the positioning bracket 7. The positioning bracket 7 is installed with a telescopic component 9 for synchronously lifting the first pressing plate 8. The setting of the positioning bracket 7 can make the pressing range of the first pressing plate 8 be in the middle position of the protective film body 3, thus ensuring uniform pressing on the protective film body 3 and avoiding poor slitting effect caused by the high flexibility of the protective film body 3 during the slitting process.
[0026] A chute is opened along the length direction at the top end of the support plate 5. The slider 12 slides along the chute. Transverse racks 10 are arranged on both sides of the support plate 5. The slider 12 is located on one side of the top end of the support plate 5 facing the transverse racks 10 and is provided with an extension arm 19. At the bottom end of the extension arm 19, there is a first adjusting gear 11 that can rotate actively and meshes with the transverse rack 10. The combination of the slider 12 and the vacuum suction cups 16 can move the slit protective film body 3 to a specified distance, improving the slitting accuracy.
[0027] On the end face of the slider 12 facing the transverse rack 10, there is a longitudinal rack 13. On the outer side wall of the slider 12, there is an adsorption component connecting rod 14 that can slide longitudinally. One end of the adsorption component connecting rod 14 is installed with a second adjusting gear 18 that can rotate and meshes with the longitudinal rack 13. The bent design of the adsorption component connecting rod 14 can avoid interference between the adsorption component connecting block 15 and the second pressing plate 17 during the sliding process, ensuring the positioning effect of the second pressing plate 17 on the protective film body 3.
[0028] The bottom end of the adsorption component connecting rod 14 is provided with an adsorption component connecting block 15. A plurality of the vacuum suction cups 16 are all located at the bottom end of the adsorption component connecting block 15. The top end of the base 1 is detachably installed with an air extraction pump 4. The air extraction pump 4 is detachably connected to the vacuum suction cups 16 through an air suction pipeline. The setting of the vacuum suction cups 16 can move the protective film body 3 on one side of the slitting groove 20 to the other side of the slitting groove 20, avoiding the problems of high flexibility and low conveying accuracy of the protective film body 3.
[0029] The second pressing plate 17 is located at the top of the support plate 5. An expansion motor capable of pressing down or lifting synchronously with the first pressing plate 8 is provided at the top of the second pressing plate 17. A gap for the connecting rod 14 of the adsorption assembly to pass through is left between the first pressing plate 8 and the second pressing plate 17. The second pressing plate 17 is used to press both sides of the protective film body 3. By pressing the two side parts, during the slitting process, it can avoid the situation that the corners of the slit protective film curl or wrinkle, ensuring the slitting effect.
[0030] In the present utility model, during the slitting operation, multiple expansion motors and the expansion assembly 9 can perform synchronous pressing. The cutting blade 6 is driven to reciprocate by the threaded rod 21, and the cutting blade 6 presses down to cut the protective film body 3. After the slitting is completed, the adsorption assembly connecting block 15 is moved to the other side of the slitting groove 20 through the slide rail. The adsorption assembly connecting block 15 slides downwards, and the vacuum chuck 16 adsorbs the protective film body 3. While adsorbing, the first pressing plate 8 and the second pressing plate 17 are lifted, and the vacuum chuck 16 drives the protective film body 3 on one side of the slitting groove 20 to move to the designated slitting position, improving the slitting accuracy. At the same time, it avoids the problem that the relatively flexible protective film body 3 may naturally droop during the conveying process, resulting in difficulties in controlling the conveying direction and distance, improving the cutting precision, and ensuring the quality of the slit product.
[0031] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
