[0001] This utility model relates to the field of fabric roll plastic sealing packaging technology, and in particular to a tightening and clamping device for fabric roll plastic sealing packaging. Background Technology

[0002] In the textile industry, after the fabric rolls are produced, they usually need to be sealed in plastic to prevent dust, moisture, and pollution, and to ensure the storage quality of the fabric rolls. During the sealing process, the fabric rolls need to be stably clamped, and a tightening operation is used to ensure that the fabric rolls are tight, so as to prevent the fabric rolls from becoming loose or shifting after sealing, which would affect the packaging effect.

[0003] The clamping devices used in existing fabric roll shrink packaging are mostly plate structures. They clamp and fix the two ends of the fabric roll, but lack an effective clamping and tightening structure in the middle area. As a result, during the shrink packaging process, the middle of the fabric roll is not subjected to clamping force and is prone to loosening and bulging. This leads to poor adhesion between the shrink film and the fabric roll, thus affecting the neatness of the packaging appearance.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A tightening and clamping device for plastic sealing packaging of fabric rolls includes two frames 1, with multiple electric conveyor belts 2 arranged between the two frames 1, and clamping components 3 and lifting components 4 used in conjunction with clamping components 3 arranged at the bottom of the multiple electric conveyor belts 2. Limiting components 5 are arranged on opposite sides of the two frames 1.

[0029] The clamping assembly 3 includes a fixed shell 31. A bidirectional screw 32 is rotatably connected to the inner wall of the fixed shell 31 via a bearing. A forward and reverse motor 33 is fixedly connected to the front side of the fixed shell 31. The output shaft of the forward and reverse motor 33 is fixedly connected to one end of the bidirectional screw 32. Moving blocks 34 are sleeved on the front and rear sides of the surface of the bidirectional screw 32. The two moving blocks 34 are slidably connected to the inner wall of the fixed shell 31 on one side of each moving block 34. Fixing strips 35 are fixedly connected to the top of each moving block 34. Vertical plates 36 are fixedly connected to both sides of the top of each fixing strip 35. An arc-shaped clamping plate 37 is fixedly connected to the top of the vertical plate 36.

[0030] In this embodiment: by setting up a frame 1, an electric conveyor belt 2, a clamping assembly 3, a lifting assembly 4, and a limiting assembly 5, during use, the frame 1 provides a supporting foundation for the electric conveyor belt 2, clamping assembly 3, lifting assembly 4, and limiting assembly 5. The electric conveyor belt 2 can transport the fabric roll that needs to be plastic-sealed. The clamping assembly 3 can apply a uniform clamping force to the middle of the fabric roll, preventing the middle from bulging or loosening during plastic sealing, and ensuring that the plastic film adheres tightly to the fabric roll. It can effectively improve the neatness of the packaging appearance. The lifting component 4 can drive the clamping component 3 to rise and fall, so that the clamping component 3 will not obstruct the fabric roll conveying. When the fabric roll is conveyed, the lifting component 4 can drive the clamping component 3 to move down. When the fabric roll reaches the sealing clamping area, it can drive the clamping component 3 to rise to a suitable height to clamp and tighten the fabric roll, thereby ensuring the continuity of the fabric roll sealing packaging work. The limiting component 5 can block and limit the fabric roll when it reaches the sealing packaging area to avoid excessive fabric roll conveying.

[0031] Specifically, such as Figure 2 , Figure 4As shown, the lifting assembly 4 includes a fixed plate 41. A first lifting cylinder 42 is fixedly connected to the bottom of the fixed plate 41. The output rod of the first lifting cylinder 42 passes through the fixed plate 41 and is fixedly connected to the bottom of the fixed shell 31. Limiting guide rods 43 are provided on the front and rear sides of the first lifting cylinder 42. The bottoms of the two limiting guide rods 43 are fixedly connected to the front and rear sides of the bottom of the fixed shell 31, respectively. The bottoms of the two limiting guide rods 43 both pass through to the bottom of the fixed plate 41.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, support frames 44 are fixedly connected to the front and rear sides of both sides of the fixed plate 41, and the side of the support frame 44 closest to the frame 1 is fixedly connected to the frame 1.

[0033] Specifically, such as Figure 4 As shown, the bottom of the fixing plate 41 is provided with a first through hole 6 that is used in conjunction with the first lifting cylinder 42. The surface of the output rod of the first lifting cylinder 42 is slidably connected to the inner wall of the first through hole 6. The front and rear sides of the top of the fixing plate 41 are provided with sliding holes 7 that are used in conjunction with the limiting guide rod 43. The surface of the limiting guide rod 43 is slidably connected to the inner wall of the sliding hole 7.

[0034] In this embodiment: by setting a fixed plate 41, a first lifting cylinder 42, a limiting guide rod 43, a support frame 44, a first through hole 6, and a sliding hole 7, in use, by activating the first lifting cylinder 42 at the bottom of the fixed plate 41, the output rod of the first lifting cylinder 42 drives the fixed shell 31 to move upward. At the same time, the limiting guide rods 43 on both sides of the bottom of the fixed shell 31 slide synchronously along the sliding hole 7 on the fixed plate 41, ensuring that the fixed shell 31 rises smoothly until the arc-shaped clamping plate 37 in the clamping assembly 3 moves to a height that matches the middle of the fabric roll. The first lifting cylinder... After cylinder 42 stops working, the fabric roll needs to be conveyed to the next process after the sealing is completed. This can be achieved by starting the first lifting cylinder 42 to drive the fixed shell 31 and the entire clamping assembly 3 to move down and reset, so that the clamping assembly 3 will not obstruct the fabric roll conveying. The support frame 44 can support and fix the fixed plate 41. The first through hole 6 allows the output rod of the first lifting cylinder 42 to pass through the fixed plate 41 for lifting and output. The sliding hole 7 allows the limit guide rod 43 to slide up and down through the fixed plate 41.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the limiting component 5 includes a fixing block 51. The side of the fixing block 51 closest to the frame 1 is fixedly connected to the frame 1. The bottom side of the fixing block 51 away from the frame 1 is fixedly connected to a second lifting cylinder 52. The output rod of the second lifting cylinder 52 passes through the fixing block 51 and is fixedly connected to a limiting stop bar 53.

[0036] Specifically, such as Figure 5 As shown, a second through hole 8 is provided on the side of the bottom of the fixing block 51 away from the frame 1, which is used in conjunction with the second lifting cylinder 52. The output rod surface of the second lifting cylinder 52 is slidably connected to the inner wall of the second through hole 8.

[0037] In this embodiment: by setting a fixed block 51, a second lifting cylinder 52, a limiting stop bar 53, and a second through hole 8, in use, by activating the second lifting cylinder 52 at the bottom of the fixed block 51, the output rod of the second lifting cylinder 52 drives the limiting stop bar 53 to move upward to a suitable height, which can block and limit the fabric roll, preventing the fabric roll from being over-fed. After the fabric roll has completed the sealing work, by activating the second lifting cylinder 52, the limiting stop bar 53 is driven downward to reset, preparing for the next limiting work.

[0038] Specifically, such as Figure 3 As shown, both movable blocks 34 have threaded holes 9 inside that cooperate with the bidirectional screw 32. The two movable blocks 34 are respectively threaded to the front and rear sides of the surface of the bidirectional screw 32 through the threaded holes 9.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, an arc-shaped rubber pad 10 is fixedly connected to the inner side of the arc-shaped clamp 37, and the inner side of the arc-shaped rubber pad 10 is provided with anti-slip texture.

[0040] In this embodiment: by setting threaded holes 9, so that the two moving blocks 34 can move closer or further apart synchronously under the action of the threads when the bidirectional screw 32 rotates, and by setting arc-shaped rubber pads 10, the fabric roll can be prevented from being pinched and the clamping friction can be increased.

[0041] Specifically, such as Figure 1 , Figure 2 As shown, a PLC controller 11 is provided on the front right side of one of the two frames 1, which works in conjunction with the electric conveyor belt 2, the clamping assembly 3, the lifting assembly 4 and the limiting assembly 5. The PLC controller 11 is electrically connected to the electric conveyor belt 2, the clamping assembly 3, the lifting assembly 4 and the limiting assembly 5.

[0042] Specifically, such as Figure 1 , Figure 2 As shown, a fixed bracket 12 is fixedly connected to the bottom of the PLC controller 11, and the fixed bracket 12 is fixedly connected to the frame 1 on the side near the frame 1.

[0043] In this embodiment: by setting up a PLC controller 11, the electric conveyor belt 2, clamping assembly 3, lifting assembly 4 and limiting assembly 5 can be controlled to achieve coordinated operation. By setting up a fixed bracket 12, the PLC controller 11 can be supported and fixed.

[0044] Working Principle: In operation, the working parameters of each component are first set via the PLC controller 11. When the fabric roll is being shrink-wrapped, the controller starts the electric conveyor belt 2, which moves the fabric roll towards the shrink-wrapping clamping area. When the fabric roll is about to reach the designated area, the PLC controller 11 activates the second lifting cylinders 52 in the two limit components 5. This causes the output rods of the two second lifting cylinders 52 to move the limit bars 53 upwards to a suitable height, thus blocking and limiting the fabric roll to prevent over-feeding. At this point, the PLC controller 11 stops the electric conveyor belt 2. Then, the PLC controller... 11. The first lifting cylinder 42 in the bottom lifting assembly 4 of the electric conveyor belt 2 is activated, causing the output rod of the first lifting cylinder 42 to drive the fixed shell 31 to move upward. At the same time, the limit guide rods 43 on both sides of the bottom of the fixed shell 31 slide synchronously along the sliding holes 7 on the fixed plate 41 to ensure that the fixed shell 31 rises smoothly until the arc-shaped clamping plate 37 in the clamping assembly 3 moves to a height that matches the middle of the fabric roll. The first lifting cylinder 42 stops working. Then, the PLC controller 11 starts the forward and reverse motor 33 in the clamping assembly 3, causing the output shaft of the forward and reverse motor 33 to drive the bidirectional screw 32, which is rotatably connected to the inner wall of the fixed shell 31 through the bearing, to rotate. Due to the bidirectional screw... The threads on the front and rear sides of the rod 32 are in opposite directions, and the two moving blocks 34 are respectively connected to the front and rear threads of the bidirectional screw 32 through the internal threaded holes 9. At the same time, the side of the moving block 34 closest to the inner wall of the fixed shell 31 is slidably connected to the inner wall of the fixed shell 31. Thus, the rotation of the bidirectional screw 32 can drive the two moving blocks 34 to move synchronously relative to each other along the inner wall of the fixed shell 31. The two moving blocks 34 will drive the two fixing bars 35 to move synchronously relative to each other. The two fixing bars 35 will drive the two sets of arc-shaped clamping plates 37 to move relative to each other through the upright plates 36 on both sides of the top, until the arc-shaped rubber pads 10 on the inner side of the two sets of arc-shaped clamping plates 37 are in close contact with the middle of the fabric roll. The anti-slip texture on the inner side of the arc-shaped rubber pad 10 enhances the friction with the fabric roll, achieving stable clamping of the middle of the fabric roll and preventing bulging and loosening of the middle during sealing. This allows the sealing film to adhere tightly to the fabric roll. After the fabric roll is sealed, the PLC controller 11 controls the forward and reverse motor 33 to reverse, driving the bidirectional screw 32 to reverse, causing the two moving blocks 34 to move in opposite directions, so that the two sets of arc-shaped clamps 37 are detached from the fabric roll. Then, the first lifting cylinder 42 drives the fixed shell 31 and the clamping assembly 3 to move down and reset, and the second lifting cylinder 52 drives the limit stop 53 to move down and reset. Finally, the electric conveyor belt 2 starts to transport the sealed fabric roll to the next process.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
