Description

Technical Field

[0001] This utility model belongs to the field of sheet production technology, and more specifically, relates to a storage device and a sheet production line for sheet production. Background Technology

[0002] Existing polymer sheet production lines experience intermittent pauses and restarts during winding, causing inconsistent tension on the sheets, which is detrimental to the production of flexible sheets. Specifically, during sheet production, the packaging and cutting of the winding machine causes sudden stops and starts in the material movement at the front end. Multiple moving guide rollers within the storage rack are driven by constant torque motors to adjust the distance between the moving and fixed guide rollers. If the set torque of the constant torque motor is too high, the storage rack cannot react promptly, affecting sheet quality. If the set torque is too low, the moving guide rollers within the storage rack will move frequently, causing vibration and potentially damaging the equipment. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a storage device and sheet production line for sheet production, thereby solving the problem that existing storage racks cannot effectively cope with unstable sheet tension caused by sudden start and stop of sheet winding.

[0004] To achieve the above objectives, this utility model provides a material storage device for sheet production, comprising:

[0005] A storage rack, the storage rack comprising multiple fixed guide rollers and multiple movable guide rollers;

[0006] A buffer structure is provided on the discharge side of the storage rack. The buffer structure includes a cylinder, the telescopic end of which is connected to a buffer roller, and the air inlet end of which is connected to an air source that can provide a constant air pressure.

[0007] Optionally, the storage rack further includes:

[0008] The first support has multiple fixed guide rollers arranged on both sides of its lower part. Each side of the first support has a pair of guide rails. A movable plate is slidably arranged between each pair of guide rails. Multiple movable guide rollers are spaced apart between two movable plates.

[0009] A lifting mechanism is connected to the movable plate and is used to drive the movable plate to lift.

[0010] Optionally, the lifting mechanism includes:

[0011] A constant torque motor is provided, which is located at the lower part of the first bracket, and a first sprocket is provided on each side of the constant torque motor;

[0012] The second sprocket is located on the upper part of the first bracket and corresponds vertically to the first sprocket. The corresponding first sprocket and the second sprocket are connected by a first chain, and the first chain is connected to the moving plate by a first chain buckle.

[0013] Optionally, the storage rack further includes a baffle, which is connected to the first support and disposed below the movable plate, and the baffle is used to limit the movement of the movable plate.

[0014] Optionally, a chain guide component is connected to the baffle, which can provide guidance for the first chain.

[0015] Optionally, at least one first transition roller is provided at the feed inlet position at the lower part of the first bracket, and at least one second transition roller is provided at the discharge outlet position at the lower part of the first bracket.

[0016] Optionally, the buffer structure further includes:

[0017] The second bracket has a cylinder on each of its two sides;

[0018] Two third sprockets are rotatably connected to the telescopic end of the cylinder;

[0019] The second chain has one end connected to the second bracket, and the other end of the second chain passes around the third sprocket and is connected to a slider. The two ends of the buffer roller are rotatably connected to the slider.

[0020] Two slide rails are vertically arranged on both sides of the second bracket, and the slider slides in cooperation with the slide rails.

[0024] This utility model provides a storage device and a sheet production line for sheet production lines. Its advantages are as follows: the storage device for sheet production lines has a buffer structure on the discharge side of the storage rack. The buffer structure has an air source connected to provide it with constant air pressure. The sheet material output from the discharge port of the storage rack passes over the buffer roller on the telescopic end of the cylinder. Thus, when the force exerted by the sheet material on the telescopic end of the cylinder is greater than the constant air pressure, the telescopic end of the cylinder retracts; when the force exerted by the sheet material on the telescopic end of the cylinder is not greater than the constant air pressure, the cylinder... The telescopic end will extend, and with the setting of cylinder and buffer roller, a buffer is performed on the outside of the material outlet of the storage rack. The movement of the buffer roller can buffer the start and stop of the sheet movement during the sheet production process. At the same time, the movement of multiple moving guide rollers in the storage rack is used to store and release materials, just like the storage rack in the existing technology. The buffer structure and the storage rack work together to better adapt to the sudden start and stop of the sheet material movement, and ensure that the tension of the sheet is not too large, and also ensure the smooth operation of the entire storage device.

[0030] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0031] like Figure 1 As shown, this utility model provides a storage device for sheet material production, comprising:

[0032] Storage rack 1, which includes multiple fixed guide rollers 2 and multiple movable guide rollers 3;

[0033] The buffer structure 4 is set on the discharge side of the storage rack 1. The buffer structure 4 includes a cylinder 5. The telescopic end of the cylinder 5 is connected to a buffer roller 6. The air inlet end of the cylinder 5 is connected to an air source that can provide constant air pressure.

[0034] Specifically, to address the problem in existing technologies where the storage rack 1 struggles to effectively handle unstable sheet tension caused by sudden starts and stops during sheet winding, this invention provides a storage device for sheet production lines. This device includes a buffer structure 4 on the discharge side of the storage rack 1. The buffer structure 4 has an air source connected to provide it with constant air pressure. The sheet material output from the discharge port of the storage rack 1 passes over the buffer roller 6 on the telescopic end of the cylinder 5. Thus, when the force exerted by the sheet material on the telescopic end of the cylinder 5 exceeds the constant air pressure, the telescopic end of the cylinder 5 retracts; when the force exerted by the sheet material on the telescopic end of the cylinder 5 is less than the constant air pressure, the retraction of the cylinder 5 is reversed. When the air pressure is constant, the telescopic end of the cylinder 5 will extend. With the cylinder 5 and the buffer roller 6, a buffer is performed on the outside of the discharge port of the storage rack 1. The movement of the buffer roller 6 can buffer the start and stop of the sheet movement during the sheet production process. At the same time, the movement of multiple moving guide rollers 3 in the storage rack 1 is used to store and release materials as in the existing storage rack 1. The buffer structure 4 and the storage rack 1 work together to better adapt to the sudden start and stop of the sheet material movement, and ensure that the tension of the sheet is not too high, and also ensure that the entire storage device operates smoothly.

[0035] Optionally, the storage rack 1 also includes:

[0036] The first support 7 has multiple fixed guide rollers 2 arranged on both sides of the lower part of the first support 7. A pair of guide rails 8 are arranged on each side of the first support 7. A movable plate 9 is slidably arranged between each pair of guide rails 8. Multiple movable guide rollers 3 are spaced between the two movable plates 9.

[0037] The lifting mechanism is connected to the movable plate 9 and is used to drive the movable plate 9 to lift.

[0038] Specifically, the first support 7 is the frame of the storage rack 1. Two movable plates 9 are respectively set at the two ends of the first support 7 and are respectively located between a pair of guide rails 8. Under the drive of the lifting mechanism, the movable plates 9 can be lifted and lowered to adjust the distance between the movable guide roller 3 and the fixed guide roller 2, so as to play the role of receiving and releasing the sheet material.

[0039] In this embodiment, guide wheels 10 are provided at both ends of the movable plate 9. The guide wheels 10 roll in cooperation with the guide rail 8 to guide the lifting and lowering of the movable plate 9.

[0040] Optionally, the lifting mechanism includes:

[0041] A constant torque motor 11 is located at the lower part of the first bracket 7, and a first sprocket 12 is provided on each side of the constant torque motor 11.

[0042] The second sprocket 13 is located on the upper part of the first bracket 7 and corresponds vertically to the first sprocket 12. The corresponding first sprocket 12 and second sprocket 13 are connected by the first chain 14, and the first chain 14 is connected to the moving plate 9 by the first chain buckle 15.

[0043] Specifically, the constant torque motor 11 enables the lifting mechanism to automatically adjust the height of the moving plate 9 according to the tension of the sheet. When the tension of the sheet is too high, the constant torque motor 11 drives the second sprocket 13 to rotate in order to maintain its constant torque, causing the first chain buckle 15 and the moving plate 9 to descend, thereby reducing the tension of the sheet by releasing the material in the storage rack 1. Conversely, the constant torque motor 11 rotates in the opposite direction.

[0044] Furthermore, the tension of the sheet is affected by the sheet winding operation. Due to the setting of the buffer structure 4, when the tension of the sheet suddenly increases significantly, the retraction end of the cylinder 5 of the buffer structure 4 is first used for buffering, and then the constant torque motor 11 is used for adjustment. Therefore, the set torque of the constant torque motor 11 in the storage device can have a large set threshold range.

[0045] Optionally, the storage rack 1 further includes a baffle 16, which is connected to the first support 7 and disposed below the movable plate 9. The baffle 16 is used to limit the movement of the movable plate 9.

[0046] Specifically, the baffle 16 is used to limit the movement of the moving plate 9 to prevent it from descending excessively.

[0047] Optionally, a chain guide component 17 is connected to the baffle 16, which can provide guidance for the first chain 14.

[0048] Specifically, the chain guide component 17 is used to limit the left and right swaying of the first chain 14 during operation, guide the first chain 14, and improve the stability of the lifting mechanism during operation.

[0049] In this embodiment, the chain guide component 17 may adopt a second chain 22 buckle. The second chain 22 buckle does not fasten the first chain 14, but only limits the first chain 14, restricting its left and right swaying and playing a guiding role.

[0050] Optionally, at least one first transition roller 18 is provided at the feed inlet position at the lower part of the first support 7, and at least one second transition roller 19 is provided at the discharge outlet position at the lower part of the first support 7.

[0051] Specifically, the inlet and outlet of the storage rack 1 are both located at the lower part of the first support 7. The inlet and outlet are respectively equipped with a first transition roller 18 and a second transition roller 19, which provide transition and guidance for the sheet material to enter and exit the storage rack 1, and ensure that the direction of feeding and discharging is convenient for the operation of the storage rack 1 and the buffer structure 4.

[0052] In this embodiment, there are two first transition rollers 18. The sheet material first passes over the upper side of the first first transition roller 18, then passes over the lower side of the second first transition roller 18, then passes upward through a moving guide roller 3, then passes downward through a fixed guide roller 2, and then passes over each moving guide roller 3 and fixed guide roller 2 one by one, until it passes over the lower side of a second transition roller 19 and is output from the outlet.

[0053] Optionally, buffer structure 4 also includes:

[0054] The second bracket 20 has a cylinder 5 on each of its two sides;

[0055] Two third sprockets 21 are rotatably connected to the telescopic end of cylinder 5;

[0056] The second chain 22 has one end connected to the second bracket 20 and the other end of the second chain 22 passes around the third sprocket 21 and is connected to the slider 23. The two ends of the buffer roller 6 are rotatably connected to the slider 23.

[0057] Two slide rails 24 are vertically arranged on both sides of the second bracket 20, and the slider 23 slides in cooperation with the slide rails 24.

[0058] Specifically, the second support 20 is the frame of the buffer structure 4. Two cylinders 5 are respectively set at the two transverse ends of the second support 20. A slide rail 24 is also set at each of the two transverse ends of the second support 20. The slide rail 24 is slidably connected to the slider 23 to guide the slider 23. The lifting and lowering of the slider 23 is driven by the second chain 22. The second chain 22 passes around the third sprocket 21. The third sprocket 21 is driven by the extension end of the cylinder 5.

[0059] Optionally, the telescopic end of the cylinder 5 is positioned upwards, and a steering roller 25 is provided on the lower side of the end of the second bracket 20 away from the storage rack 1.

[0060] Specifically, when the telescopic end of cylinder 5 retracts, the third sprocket 21 descends, causing the end of the second chain 22 that bypasses the third sprocket 21 and connects to the slider 23 to move, thereby causing the buffer roller 6 connected between the two sliders 23 to move, thus achieving buffering of the tension of the sheet material. The steering roller 25 changes the transmission direction of the sheet material on the discharge side of the buffer structure 4, which facilitates the subsequent processes.

[0061] In this embodiment, the sheet material that passes under the second transition roller 19 passes over the upper side of the buffer roller 6, then passes under the lower side of the steering roller 25, and then is output backward.

[0062] This utility model also provides a sheet production line, including the above-mentioned storage device for the sheet production line.

[0063] Optionally, the sheet production line also includes an extruder and a winding machine, with a storage device for the sheet production line located between the extruder and the winding machine.

[0064] Specifically, the sheet material output from the extruder has relatively stable tension. The sheet material passes through the storage rack 1 and the buffer structure 4 in sequence, and then enters the winding machine for winding. During the winding process, the sheet material may suddenly start or stop, causing a sudden change in the tension of the sheet material. Under the action of the buffer structure 4, the tension change of the sheet material can be buffered first. Then, the lifting mechanism driven by the constant torque motor 11 in the storage rack 1 drives the moving guide roller 3 to rise and fall, thereby achieving a further effect of stabilizing the tension.

[0065] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
