Description

Technical Field

[0001] This utility model relates to the field of chemical fiber equipment technology, specifically a limiting device for a drawing machine. Background Technology

[0002] Drawing machines are widely used in the fiber production industry, playing a role in stretching fibers during the fiber production process. A search revealed a limiting device for a drawing machine in Chinese Patent No. CN215440779U, which includes two limiting rods spaced apart on the drawing machine body, each rod perpendicular to a roller on the machine body. This application, by using two limiting rods, allows the fiber bundle to pass through the gap between the two rods during fiber stretching. This allows the two rods to limit the fibers on both sides of the fiber bundle, causing them to converge towards the center. This increases the thickness on both sides of the fiber bundle, maintaining a thickness as consistent as possible with the center, thus ensuring that the stretching force on the fibers in the bundle is as uniform as possible, ultimately increasing the quality stability of the fibers produced by the drawing machine.

[0003] However, in actual use, this solution can only limit the fibers in the current area because the limiting structure formed by the limiting rod and the support rod is fixed in a designated position. Once the fibers leave the area, they may shift again, which is not conducive to the normal use of the drawing machine. Utility Model Content

[0004] To address the problem that existing limiting devices cannot fully restrict the range of fiber movement, this invention provides a limiting device for a drawing machine.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A limiting device for a drawing machine includes a drawing machine body, a base plate mounted on the bottom end of the drawing machine body, a groove formed on the top surface of the base plate, a lead screw rotatably connected inside the groove, a sliding plate on the top surface of the base plate, the bottom end of the sliding plate extending into the groove and threadedly connected to one end of the lead screw, a servo motor mounted on one side of the outer wall of the base plate, the output end of the servo motor extending into the groove and drivingly connected to one end of the lead screw, and a plurality of through holes formed on the outer wall of the sliding plate, with limiting cylinders disposed inside the plurality of through holes.

[0007] Furthermore, the limiting cylinder includes a cylinder body, the cylinder body is rotatably connected inside the through hole, and a first side ring and a second side ring are respectively connected to both ends of the cylinder body, the first side ring and the second side ring being located inside the through hole.

[0008] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the first side ring and the second side ring, the cylinder can be confined inside the through hole.

[0009] Furthermore, the outer walls of the first and second side rings are flush with the sides of the slide plate, respectively.

[0010] The beneficial effect of adopting the above-mentioned further solution is that by utilizing the positional relationship between the first side ring, the second side ring and the skateboard, the flatness of both sides of the skateboard can be maintained, thereby reducing wear on the fibers.

[0011] Furthermore, a drive roller is provided on one side of the drawing machine body. The drive roller includes a roller body, one end of which is connected to a shaft. One end of the shaft is rotatably connected to the outer wall of the drawing machine body. The advantage of adopting the above-mentioned further solution is that the connection of the shaft facilitates the rotation of the roller body on one side of the drawing machine body.

[0012] Furthermore, the outer wall of the roller body fits into the inner wall of the cylinder body.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, through the dimensional relationship between the roller and the cylinder, it is convenient for the roller to extend into the interior of the cylinder, which is beneficial for adjusting the winding size of the roller.

[0014] Furthermore, the outer wall of the roller is provided with scale lines.

[0015] The advantage of adopting the above-mentioned further solution is that the setting of scale lines makes it easier to observe the required limit size value in real time.

[0016] Furthermore, retainers are provided on both sides of the skateboard. Each retainer includes a frame, and a bolt is inserted and connected to one side of the frame. The frame is connected to the outer wall of the skateboard by the bolt.

[0017] The advantage of adopting the above-mentioned further solution is that the use of bolts allows for a detachable connection between the frame and the slide plate.

[0018] Furthermore, a protrusion is provided on one side of the frame, and side grooves that engage with the protrusion are respectively provided on both sides of the outer wall of the base plate.

[0019] The advantage of adopting the above-mentioned further solution is that, by sliding the protrusion inside the side groove, the two sets of retainers can maintain the smoothness of the slide plate movement.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This type of drawing machine uses a limiting device that, through the cooperation of a base plate, a slide groove, a lead screw, a slide plate, a servo motor, and a limiting cylinder, can achieve multi-directional limiting of the fiber, effectively preventing the fiber from shifting in the drawing machine. Specifically, the lead screw is driven to rotate by the output end of the servo motor, and in conjunction with the threaded connection between the lead screw and the slide plate, the slide plate can drive the limiting cylinder to slide back and forth on the top surface of the base plate until the limiting cylinder approaches one side of the drawing machine body and interlocks with the drive roller, thereby limiting the fiber conveyed on the drive roller.

[0031] 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.

[0032] Example 2

[0033] Please see Figures 1-5 As an embodiment of this utility model, the limiting cylinder 400 further includes a cylinder body 4001, which is rotatably connected to the inside of the through hole. A first side ring 4002 and a second side ring 4003 are respectively connected to both ends of the cylinder body 4001. The first side ring 4002 and the second side ring 4003 are located inside the through hole. Through the cooperation of the first side ring 4002 and the second side ring 4003, the cylinder body 4001 can be limited inside the through hole. The outer walls of the first side ring 4002 and the second side ring 4003 are respectively connected to the two sides of the sliding plate 300. By utilizing the positional relationship between the first side ring 4002, the second side ring 4003 and the slide plate 300, the flatness of both sides of the slide plate 300 can be maintained, thereby reducing wear on the fibers. A drive roller 700 is provided on one side of the drawing machine body 100. The drive roller 700 includes a roller body 7001. One end of the roller body 7001 is connected to a shaft 7002.

Through the connection of the shaft 7002, it is convenient for the roller body 7001 to rotate on one side of the drawing machine body 100.

[0034] Example 3

[0035] Please see Figures 1-5 As an embodiment of this utility model, the outer wall of the roller 7001 matches the inner wall of the cylinder 4001. The dimensional relationship between the roller 7001 and the cylinder 4001 facilitates the extension of the roller 7001 into the interior of the cylinder 4001, which is beneficial for adjusting the winding size of the roller 7001. The outer wall of the roller 7001 is provided with scale lines 7003, which facilitates real-time observation of the required limit dimensions. Holders 600 are respectively provided on both sides of the slide plate 300. Each holder 600 includes a frame body 600. 1. A bolt 6003 is inserted and connected to one side of the frame 6001. The frame 6001 is connected to the outer wall of the slide plate 300 through the bolt 6003. The use of the bolt 6003 allows the frame 6001 and the slide plate 300 to be detachably connected. A protrusion 6002 is provided on one side of the frame 6001. Side grooves 800 that engage with the protrusion 6002 are respectively opened on both sides of the outer wall of the base plate 200. By sliding the protrusion 6002 inside the side groove 800, the two sets of retainers 600 can maintain the stability of the slide plate 300.

[0036] Specifically, the working principle of this type of limiting device for a drawing machine is as follows: First, the device is moved to the designated working area and started for operational testing. After ensuring normal operation, it is then put into use. Specifically, by starting the servo motor 500, its output drives the lead screw 1000 to rotate. Combined with the threaded connection between the lead screw 1000 and the slide plate 300, the slide plate 300 can drive the limiting cylinder 400 to slide back and forth on the top surface of the base plate 200. Simultaneously, the scale line 7003 on the outer wall of the roller body 7001 is observed. The required limiting dimensions are recorded in real time until the limiting cylinder 400 approaches one side of the drawing machine body 100 and interlocks with the drive roller 700, thereby limiting the fiber conveyed on the drive roller 700. Secondly, through the cooperation of the first side ring 4002 and the second side ring 4003, the cylinder 4001 can be restricted inside the through hole. Furthermore, by utilizing the positional relationship between the first side ring 4002, the second side ring 4003 and the slide plate 300, the flatness of both sides of the slide plate 300 can be maintained, thereby reducing wear on the fiber.
