Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a protective film winding machine. Background Art

[0002] Protective film wrapping machine, also known as wrapping packaging machine or stretch film machine, is a mechanical device used to protect the packaging of items. It wraps the items by rotating and stretching the film to achieve the effect of protection and fixation. Usually, the protective film wrapping machine only wraps the cylindrical part when wrapping part of the film roll material.

[0003] According to the Chinese patent announcement number CN210617288U, "A semi-automatic wrapping machine for pipe protective film", it mainly describes the process of wrapping the pipe protective film by moving linearly along the first pipe support and the second pipe support, and the protective film rotates around the winding mechanism support along with the winding mechanism, and the two are combined to complete the pipe protective film wrapping work. Since the first pipe support and the second pipe support are open structures, the length of the pipe is not affected. After the winding work is completed, the pipe runs directly out of the device from the end of the second pipe support, and the next pipe to be wrapped is directly fed in without stopping the machine. This device is very easy to operate automatically throughout the entire process. Compared with manual winding, the protective film is evenly arranged and the work efficiency is significantly improved. In this process, when wrapping the film roll, only the cylindrical part of the film roll material is wrapped, and the protection effect on both sides of the film roll is reduced, which is easy to be damaged in the subsequent process.

[0004] Therefore, a protective film wrapping machine is proposed to solve the problem that in this process, only the cylindrical part of the film roll material is wrapped when wrapping the film roll, the protection effect on both sides of the film roll is reduced, and it is easy to be damaged in the subsequent process.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1-3 The protective film wrapping machine shown in the figure includes a fixed frame 1 and a conveying device 2. The conveying device 2 is driven by a driving motor to drive the conveyor belt to rotate. A support plate 3 is fixedly connected between the two fixed frames 1. The two sides of the upper end of the support plate 3 that are away from each other are fixedly connected with a first push rod 4. The first push rod 4, the second push rod 13 and the third push rod 20 are all electric push rods. A connecting block 5 is sleeved on the first push rod 4. The opposite side of the two connecting blocks 5 is fixedly connected with a fixing ring 6. A protrusion is fixedly connected to the fixing ring 6 and one side of the protrusion is fixedly connected to the driving motor. The output end of the driving motor is fixedly connected to a driving gear 7. An auxiliary gear 8 is engaged with one side of the driving gear 7. The auxiliary gear 8 is rotatably connected to the fixing ring 6. The driving gear The wheel 7 drives the auxiliary gear 8 to rotate, and causes the card strip 9 and the protective film roller 23 to rotate. The card strip 9 is fixedly connected to one side of the auxiliary gear 8, and the second push rod 13 is fixedly connected to the two sides away from each other on the fixed frame 1. The output end of the second push rod 13 is fixedly connected to the movable plate 14, and the bottom end of the movable plate 14 is evenly fixedly connected to two opposite fixed plates 15. The second push rod 13 drives the movable plate 14 to move up and down, and a screw 16 is rotatably connected between the two adjacent fixed plates 15. A moving bar 17 is threadedly connected to the screw 16, and a fixed disk 18 is fixedly connected to the bottom side of the moving bar 17. The fixed disk 18 is fixedly connected to a support rod 19 on the side away from the moving bar 17, and an extrusion disk 21 is sleeved on the support rod 19.

[0018] Among them, the pressure plate 21 is fixedly connected to the output end of the third push rod 20, and the third push rod 20 is fixedly connected to one side of the movable bar 17. By setting the third push rod 20 to drive the pressure plate 21 to extend, the protective film attached to the support rod 19 can be pushed to be closed on both sides of the film roll material.

[0019] Among them, a protective film roller 23 is sleeved on the card strip 9, and the protective film roller 23 contacts the end of the spring ejector 12. The spring ejector 12 is inserted into the two ends of the card block 11, and the card block 11 is sleeved with the limit rod 10. The limit rod 10 is fixedly connected to the auxiliary gear 8, and the limit rod 10 is located between the two card strips 9. By setting the limit rod 10 and the spring ejector 12, the protective film roll 23 can be limited.

[0020] Among them, the limiting block is fixedly connected to one side of the limiting rod 10, and the spring is sleeved on the limiting rod 10. By arranging the limiting block and the spring, the adaptability of the limiting protective film roll can be increased.

[0021] Among them, the first push rod 4 is inserted into the end of the connecting rod 22, and the connecting rod 22 is threadedly connected to the connecting block 5. By setting the connecting rod 22, the protective film roll material of appropriate diameter can be replaced.

[0022] Working principle: The film roll material is placed on the conveying device 2 on the fixed frame 1, and the conveying device 2 drives the film roll material to move. At this time, the rotation of the screw 16 and the contraction of the second push rod 13 are used to make the support rod 19 contact both sides of the film roll material, and then the driving motors on the two fixed plates 15 are controlled and cooperated with the conveying device 2 to move the film roll material. At this time, the driving motor on the protrusion drives the driving gear 7 and the auxiliary gear 8 to rotate, and makes the card strip 9 and the protective film roll 23 rotate. At this time, the film on the protective film roll 23 is attached to the film roll material, and part of the film will be wound around the support rod 19. After the film roll material is completely attached, start the third push rod 20 and make the pressure plate 21 move on the support rod 19, and push the film attached to the support rod 19 gradually close to the two sides of the film roll material, thereby closing the two ends of the protective film and improving the protection of the film roll material.
