Description

Technical Field

[0001] This utility model belongs to the field of support device technology, specifically relating to a roll support device for producing carbon fiber prepreg. Background Technology

[0002] In the continuous production of carbon fiber composite products, carbon fiber prepreg, as an intermediate product, is typically transferred between processes in roll form. After the prepreg roll is wound up, it usually needs to be transferred from the initial station to different downstream processing equipment, such as slitting machines, automatic feeders, or automatic tape layers, for subsequent unwinding. Therefore, specialized support devices are required to support both ends of the roll mandrel, serving as temporary supports and moving tools.

[0003] Currently, when transferring such rolls within a workshop, wheeled support frames are commonly used to support both ends of the mandrel for movement. However, in actual operation, different processing equipment requires different installation heights for the rolls, necessitating adjustments to the roll height to suit various needs. Existing support devices are not convenient for adjusting the roll height; therefore, a roll support device for producing carbon fiber prepreg is urgently needed.

[0004] A patent with publication number CN215467157U discloses a support structure for the head of an automatic uncoiler drum. This structure includes a support plate, a motor, a rotating shaft, sliding blocks, a mating rod, a first bevel gear, a second bevel gear, and a movable rod. When the height of the support plate needs adjustment, the motor is started, and the output shaft drives the rotating shaft to rotate. Two threads on the rotating shaft then move two sliding blocks, which in turn raise or lower the support plate via the mating rod. Simultaneously, the rotation of the rotating shaft also drives a fixed rod to rotate through the meshing of the first and second bevel gears, which in turn raises or lowers the support plate via the movable rod, thus improving support stability.

[0005] While the aforementioned solution provides the support structure with ease of movement by incorporating wheels, its stability suffers from serious deficiencies. Once in place, the entire support foundation relies entirely on the wheel system, resulting in significantly insufficient anti-slip and anti-sway capabilities. During hoisting or relocation operations, even the slightest displacement can trigger support instability. This instability can easily cause the drum shaft to slip off the support point, posing a direct threat to the personal safety of operators and creating a serious safety hazard. This severely limits the practical application value of this device in industrial production environments requiring high stability. Utility Model Content

[0012] Furthermore, the transmission component includes a connecting rod, one end of which is hinged to the support base, and the other end of which is hinged to the slider.

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a roll support device for producing carbon fiber prepreg includes a base 1, a fixing plate 6 is fixedly installed on the top of the base 1, and a first vertical cylinder 8 is fixedly installed on the top of the fixing plate 6; a first piston assembly 16 is slidably sealed inside the first vertical cylinder 8, and a support seat 9 is slidably limited and installed above the first vertical cylinder 8 in the vertical direction, and the first piston assembly 16 is fixedly connected to the support seat 9.

[0028] Specifically, such as Figure 2 As shown, the first piston assembly 16 includes a first piston and a first piston rod. The first piston is sealed and slidably disposed inside the first vertical cylinder 8 along the vertical direction. The first piston rod is fixedly disposed on the top of the first piston. The top of the first piston rod slides through the first vertical cylinder 8 and is fixedly connected to the support seat 9.

[0029] In addition, the top of the support base 9 is provided with a placement component. Two sets of placement components are symmetrically arranged. The two sets of placement components are used to support and limit the two ends of the drum spindle.

[0030] Specifically, such as Figures 1-2As shown, the placement assembly includes a placement plate 31. The top of the support base 9 is both fixedly mounted on the placement plate 31 and slidably mounted on a limiting plate 18. The limiting plate 18 abuts against the placement plate 31 via an elastic element. A clamping block 15 is slidably mounted vertically on the side of the limiting plate 18 facing the placement plate 31. A first spring 19 is provided between the clamping block 15 and the limiting plate 18.

[0031] More specifically, the elastic element includes a fourth spring 29. A connecting plate is integrally fixedly installed on the top of the support base 9. A sliding rod 32 is slidably installed through the upper limit of the connecting plate. One end of the sliding rod 32 is fixedly connected to the limiting plate 18. The fourth spring 29 is sleeved on the outer surface of the sliding rod 32. One end of the fourth spring 29 is fixedly connected to the limiting plate 18, and the other end is fixedly connected to the connecting plate.

[0032] The limiting plate 18, in conjunction with the fourth spring 29, is used to limit the drum laterally, and the clamping block 15, the first spring 19, and the placement plate 31 are used to limit the drum longitudinally.

[0033] In addition, a number of sliders 13 are provided in the base 1 for limiting sliding. Each slider 13 is provided with a transmission component between it and the support base 9. The sliders 13 correspond to each other in pairs, and the two corresponding sliders 13 slide towards each other or away from each other. The base 1 is provided with a driving mechanism that acts on the sliders 13.

[0034] Specifically, the transmission component includes a connecting rod 10, one end of which is hinged to the support base 9, and the other end of which is hinged to the slider 13.

[0035] Specifically, the drive mechanism includes a motor 28, which is fixedly embedded in the base 1. The output shaft of the motor 28 is fixedly fitted with a first pulley 12. A bidirectional threaded rod 5 is rotatably mounted horizontally inside the base 1. A second pulley 11 is fixedly mounted at one end of the bidirectional threaded rod 5. A belt is fitted between the first pulley 12 and the second pulley 11 for transmission. Two corresponding sliders 13 correspond one-to-one with two threaded sections of the bidirectional threaded rod 5, and each slider 13 is threaded onto the corresponding threaded section.

[0036] Start the motor 28, which drives the two corresponding sliders 13 to slide towards or away from each other, thereby adjusting the height of the support base 9 and the drum.

[0037] In addition, such as Figure 2 As shown, a horizontal cylinder 3, an oil tank 4, and a second vertical cylinder 26 are fixedly installed inside the base 1. The oil tank 4 and the horizontal cylinder 3 are connected by an oil pump 7. The horizontal cylinder 3 is connected to the first vertical cylinder 8 and the second vertical cylinder 26 through a first connecting pipe 17. An obstruction component acting on the first connecting pipe 17 is provided inside the horizontal cylinder 3.

[0038] Furthermore, a support block 14 for supporting the horizontal cylinder 3 is fixedly installed inside the base 1.

[0039] Furthermore, such as Figure 2 As shown, the obstruction component is installed inside the horizontal cylinder 3. The left chamber of the horizontal cylinder 3 is connected to the lower chamber of the first vertical cylinder 8 through the first connecting pipe 17. The upper chamber of the first vertical cylinder 8 is connected to the external environment through the air hole. The lower chamber of the first vertical cylinder 8 is connected to the right chamber of the horizontal cylinder 3 through the second connecting pipe 30. The second connecting pipe 30 has a built-in control valve.

[0040] Specifically, such as Figure 3 As shown, the obstruction assembly includes a baffle 23, which is fixedly installed inside the cross cylinder 3. The baffle 23 has an opening in the middle, and a movable block 21 is slidably sealed at the opening. A guide rod 20 is fixedly installed inside the cross cylinder 3, and the movable block 21 is slidably sleeved on the outer surface of the guide rod 20. A second spring 22 is sleeved on the outer surface of the guide rod 20, with one end of the second spring 22 fixedly connected to the guide rod 20 and the other end fixedly connected to the movable block 21.

[0041] In addition, a second piston assembly 25 is slidably sealed inside the second vertical cylinder 26, and a support plate 24 is slidably limited below the base 1. The second piston assembly 25 is fixedly connected to the support plate 24.

[0042] Specifically, such as Figure 4 As shown, the second piston assembly 25 includes a second piston and a second piston rod. The second piston is slidably and sealed within the second vertical cylinder 26 in the vertical direction. The second piston rod is fixedly mounted on the bottom of the second piston, and the bottom of the second piston rod slides through the second vertical cylinder 26 and is fixedly connected to the support plate 24. A third spring 27 is provided between the second piston and the second vertical cylinder 26. One end of the third spring 27 is fixedly connected to the second vertical cylinder 26, and the other end is fixedly connected to the second piston.

[0043] Furthermore, the bottom of the support plate 24 is provided with a rubber layer, the bottom of the second piston is provided with a pressure sensor, the base 1 is provided with a PLC control system, and the oil pump 7, motor 28 and pressure sensor are all electrically connected to the control system.

[0044] It should be noted that the elastic coefficient of the second spring 22 is greater than that of the third spring 27. The motor 28, oil pump 7, pressure sensor and PLC control system are all conventional existing technologies, and will not be described in detail in this application.

[0045] In addition, several casters 2 are rotatably mounted on the bottom of the base 1.

[0046] Working principle: When the drum needs to be placed, first push the two limiting plates 18 so that they slide back and forth and compress the fourth spring 29. Then, place both ends of the drum spindle on the two placement plates 31, push the abutment block 15 upward and compress the first spring 19. Immediately afterwards, release the two limiting plates 18 so that they move closer to each other to limit the drum laterally, while the abutment block 15 slides downward to limit the drum longitudinally.

[0047] When the height of the reel needs to be adjusted according to different equipment.

[0048] Start the oil pump 7 to pump the hydraulic oil in the oil tank 4 into the horizontal cylinder 3. Since the elastic coefficient of the second spring 22 is greater than that of the third spring 27, and in the initial state, the movable block 21 blocks the opening of the baffle 23, the hydraulic oil pumped into the horizontal cylinder 3 will first enter the second vertical cylinder 26, thereby pushing the second piston and the second piston rod in the second vertical cylinder 26 to descend and stretch the third spring 27, so that the support plate 24 descends synchronously.

[0049] When the pressure sensor at the bottom of the second piston contacts the inner wall of the bottom of the second vertical cylinder 26, the support plate 24 is in contact with the ground, thereby improving the stability of the support. At this time, the pressure sensor transmits a signal to the PLC control system, which controls the motor 28 to start. The output shaft of the second motor 28 drives the bidirectional threaded rod 5 to rotate through the transmission of the first pulley 12, the second pulley 11, and the belt, so that the corresponding two sliders 13 move closer to each other, thereby adjusting the height of the support base 9 through the connecting rod 10.

[0050] During the above process, the support seat 9 pulls the first piston and the second piston rod to slide upwards and discharge the air in the upper chamber of the first vertical cylinder 8 through the air hole, thereby raising the height of the drum. At the same time, the oil pump 7 continuously pumps hydraulic oil into the horizontal cylinder 3. As the oil pressure in the horizontal cylinder 3 increases, the movable block 21 slides to release the blockage of the baffle 23 and compresses the second spring 22, allowing the hydraulic oil in the horizontal cylinder 3 to enter the lower chamber of the first vertical cylinder 8 through the first connecting pipe 17 to fill the lower chamber of the second vertical cylinder 26, further improving the support stability.

[0051] When the height of the drum is lowered, the control valve in the second connecting pipe 30 can be opened, so that the hydraulic oil in the lower chamber of the first vertical drum 8 flows back to the horizontal drum 3 through the second connecting pipe 30, thereby achieving the height adjustment of the drum.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
