Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, and in particular to a high-strength, high-modulus polyethylene gel spinning device. Background Technology

[0002] Gel spinning equipment typically uses water or other cooling media to cool and solidify the filaments extruded from the spinneret, causing the polymer molecular chains in the spinning solution to form gel-like filaments at low temperatures, completing the transformation from liquid to solid state, and thus forming high-strength, high-modulus polyethylene fibers.

[0003] For example, Chinese Patent CN214458487U discloses a spinning machine for producing high-strength, high-modulus polyethylene fibers. When the spinning machine needs to be moved, the electric cylinder is first controlled by an external controller to push the positioning frame downward. At this time, the positioning frame will push the auxiliary support leg downward through the push rod. Then, the positioning frame continues to move downward, so that its end contacts one side of the auxiliary support leg, thereby rotating the auxiliary support leg to a vertical position. This can push the spinning machine to move its position. Moreover, at this time, the weight of the spinning machine will directly act on the auxiliary support leg. Only a small part of the lateral thrust generated by the auxiliary support leg will act on the positioning frame. The positioning frame will not convert these lateral thrusts into vertical forces. Therefore, the electric cylinder will not bear the weight of the spinning machine during the pushing process, effectively reducing the damage rate of the drive structure. After moving to the appropriate position, the electric cylinder is controlled to retract, driving the positioning frame upward. Then, the four auxiliary support legs are rotated inward and attracted to the strong magnet at the bottom of the positioning frame by the iron ball at one end of the push rod.

[0004] Regarding the aforementioned technologies, since the spinning equipment stores a large amount of liquid, resulting in its considerable weight, if all four auxiliary support legs are simultaneously rotated inwards to retract, it would be equivalent to the spinning equipment falling directly to the ground, causing a collision that would inevitably result in severe damage to the spinning equipment and spillage of the liquid. On the other hand, if the four auxiliary support legs are rotated inwards individually, it would easily cause the entire spinning equipment to tilt and eventually fall over, causing irreversible damage to the equipment and potentially leading to personnel safety accidents.

[0005] Therefore, a high-strength, high-modulus polyethylene gel spinning device is needed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a high-strength, high-modulus polyethylene gel spinning device to solve the problem that the stability of the moving structure of the spinning equipment cannot be guaranteed during the storage process, which may lead to safety accidents.

[0007] To solve the above technical problems, the technical solution adopted by this utility model is: a high-strength and high-modulus polyethylene gel spinning device, including a worktable, and a spinning device for processing high-strength and high-modulus polyethylene fibers by gel spinning is installed on the upper end of the worktable by bolts. The spinning device is existing technology and will not be described in detail here. A moving component for moving the spinning device is provided on the inner side of the worktable.

[0008] A trapezoidal plate is installed under the workbench, which provides good support during the operation of the spinning equipment.

[0009] The moving assembly includes a cavity plate bolted to the upper end of a trapezoidal plate. An air pump is bolted to one end of the cavity plate, and multiple displacement mechanisms are provided on both sides of the cavity plate. When the spinning equipment needs to be moved, the air pump continuously injects gas into the cavity plate. When the cavity plate is filled with gas, it forces the stroke of the multiple displacement mechanisms to lengthen, thus lowering their horizontal position below the trapezoidal plate and lifting the entire assembly. After the movement is completed, the air pump gradually discharges the gas from the cavity plate, which is equivalent to a vacuum operation. This allows the stroke of the multiple displacement mechanisms to return to their initial state simultaneously and slowly, thus preventing the stability of the spinning equipment from being compromised during the storage of the moving assembly.

[0010] Preferably, the displacement mechanism includes a cavity rod fixedly connected to the cavity plate. The cavity rod is connected to the cavity plate, and a support rod is slidably installed on the inner side of the cavity rod. A housing is fixedly installed at one end of the support rod, and a roller is rotatably installed on the inner side of the housing. As the air pump continuously inputs gas into the cavity plate, the gas inside the cavity plate gradually enters the cavity rod after it is filled with gas, thereby pushing the support rod to extend. Since the displacement mechanism is in an inclined state, the horizontal height of the roller will be lower than the horizontal position of the lower end face of the trapezoidal plate, thus making contact with the ground and lifting the entire worktable, which facilitates the subsequent position adjustment of the spinning equipment by the personnel.

[0011] Preferably, the trapezoidal plate has a groove on its surface, a support plate is fixedly installed on the surface of the groove, and a connecting ear is fixedly installed on the outer wall of the cavity rod. The connecting ear is connected to the support plate by bolts. By bolting the connecting ear to the support plate, it is convenient for operators to quickly install the moving component, and it can effectively distribute the pressure at the connection between the cavity rod and the cavity plate, thereby extending the service life.

[0012] Preferably, multiple sets of grooves are symmetrically formed, and multiple sets of displacement mechanisms are arranged in a one-to-one correspondence with multiple sets of grooves. The multiple sets of displacement mechanisms have the same structure. By arranging multiple sets of displacement mechanisms, on the one hand, the supporting pressure of a single set of displacement mechanisms can be effectively reduced, thereby reducing the frequency of damage. On the other hand, the overall stability of the device during movement can be effectively improved, avoiding the occurrence of safety accidents.

[0013] Preferably, multiple support legs are symmetrically installed on the surface of the trapezoidal plate. The upper end of the support legs is fixedly connected to the worktable. The weight of the spinning equipment is supported by multiple support legs to avoid damage to the cavity plate caused by excessive pressure, thereby affecting its sealing performance.

[0014] Preferably, the lower end face of the trapezoidal plate has multiple sets of anti-slip grooves, which can effectively increase the coefficient of friction with the ground and improve the stability of the spinning equipment during use.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention proposes a high-strength, high-modulus polyethylene gel spinning device. An air pump continuously injects gas into a cavity plate. Once the cavity plate is filled with gas, it forces multiple displacement mechanisms to extend their strokes, causing their horizontal position to drop below the trapezoidal plate, thus lifting the entire device. After the movement is complete, the air pump gradually expels the gas from the cavity plate, effectively creating a vacuum. This allows the strokes of the multiple displacement mechanisms to simultaneously and slowly return to their initial state, ensuring the stability of the spinning equipment during the retraction of the moving components.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] According to one embodiment of the present invention, in conjunction with Figure 1-4 The diagram shows a high-strength, high-modulus polyethylene gel spinning apparatus, including a worktable 1. A spinning device 2 for processing high-strength, high-modulus polyethylene fibers using the gel spinning method is bolted to the upper end of the worktable 1. The spinning device 2 is prior art and will not be described in detail here. A moving component 3 for moving the spinning device 2 is provided on the inner side of the worktable 1.

[0026] A trapezoidal plate 11 is provided below the workbench 1, which can provide good support during the operation of the spinning equipment 2;

[0027] The moving assembly 3 includes a cavity plate 31 bolted to the upper end face of the trapezoidal plate 11. An air pump 32 is bolted to one end of the cavity plate 31. Multiple displacement mechanisms 33 are provided on both sides of the cavity plate 31. When the spinning equipment 2 needs to be moved, the air pump 32 continuously inputs gas into the cavity plate 31. When the cavity plate 31 is filled with gas, it will force the stroke of the multiple displacement mechanisms 33 to become longer, thereby making its horizontal position lower than the trapezoidal plate 11, thus lifting the whole assembly. After the movement is completed, the air pump 32 gradually discharges the gas from the cavity plate 31. This is equivalent to a vacuum operation, which makes the stroke of the multiple displacement mechanisms 33 return to the initial state simultaneously and slowly, thereby preventing the stability of the spinning equipment 2 from being compromised during the storage process of the moving assembly 3.

[0028] Combination Figure 4As shown, the displacement mechanism 33 includes a cavity rod 331 fixedly connected to the cavity plate 31. The cavity rod 331 is connected to the cavity plate 31. A support rod 332 is slidably installed on the inner side of the cavity rod 331. A housing 333 is fixedly installed at one end of the support rod 332. A roller 334 is rotatably installed on the inner side of the housing 333. As the air pump 32 continuously inputs gas into the cavity plate 31, the gas inside the cavity plate 31 will gradually enter the cavity rod 331 after it is filled with gas, thereby pushing the support rod 332 to extend. Since the displacement mechanism 33 is in an inclined state, the horizontal height of the roller 334 will be lower than the horizontal position of the lower end face of the trapezoidal plate 11, thereby making contact with the ground and lifting the worktable 1 as a whole, which facilitates the subsequent adjustment of the position of the spinning equipment 2 by the personnel.

[0029] Combination Figure 3-4 As shown, a groove 14 is provided on the surface of the trapezoidal plate 11, and a support plate 15 is fixedly installed on the surface of the groove 14. A connecting ear 335 is fixedly installed on the outer wall of the cavity rod 331. The connecting ear 335 is connected to the support plate 15 by bolts. By bolting the connecting ear 335 to the support plate 15, it is convenient for operators to quickly install the moving component 3. On the other hand, it can effectively share the pressure at the connection between the cavity rod 331 and the cavity plate 31, thereby extending the service life.

[0030] Combination Figure 3 As shown, multiple sets of grooves 14 are symmetrically provided, and multiple sets of displacement mechanisms 33 are arranged in a one-to-one correspondence with multiple sets of grooves 14. The multiple sets of displacement mechanisms 33 have the same structure. By arranging multiple sets of displacement mechanisms 33, on the one hand, the supporting pressure of a single set of displacement mechanisms 33 can be effectively reduced, thereby reducing the frequency of damage. On the other hand, the overall stability of the device during movement can be effectively improved, avoiding the occurrence of safety accidents.

[0031] Combination Figure 3 As shown, multiple support legs 12 are symmetrically installed on the surface of the trapezoidal plate 11. The upper end face of the support legs 12 is fixedly connected to the worktable 1. The weight of the spinning equipment 2 is supported by the multiple support legs 12 to avoid damage to the cavity plate 31 caused by excessive pressure, thereby affecting its sealing performance.

[0032] Combination Figure 3 As shown, the lower end face of the trapezoidal plate 11 has multiple sets of anti-slip grooves 13, which can effectively enhance the coefficient of friction with the ground and improve the stability of the spinning equipment 2 during use.

[0033] In this embodiment, a spinning device 2 for processing high-strength and high-modulus polyethylene fibers using the gelation method is bolted to the upper end of the workbench 1. The spinning device 2 is existing technology and will not be described in detail here. A moving component 3 for moving the spinning device 2 is provided on the inner side of the workbench 1.

[0034] A trapezoidal plate 11 is provided below the workbench 1, which can provide good support during the operation of the spinning equipment 2;

[0035] The moving assembly 3 includes a cavity plate 31 bolted to the upper end face of the trapezoidal plate 11. An air pump 32 is bolted to one end of the cavity plate 31. Multiple displacement mechanisms 33 are provided on both sides of the cavity plate 31. When the spinning equipment 2 needs to be moved, the air pump 32 continuously inputs gas into the cavity plate 31. When the cavity plate 31 is filled with gas, it will force the stroke of the multiple displacement mechanisms 33 to become longer, thereby making its horizontal position lower than the trapezoidal plate 11, thus lifting the whole assembly. After the movement is completed, the air pump 32 gradually discharges the gas from the cavity plate 31. This is equivalent to a vacuum operation, which makes the stroke of the multiple displacement mechanisms 33 return to the initial state simultaneously and slowly, thereby preventing the stability of the spinning equipment 2 from being compromised during the storage process of the moving assembly 3.
