Description

Technical Field

[0001] This utility model belongs to the field of rubber sealing component manufacturing technology, specifically relating to a rubber rod limiting device. Background Technology

[0002] In the field of rubber seal manufacturing, rubber rods are the core raw material for preparing various seals such as O-rings, sealing rings, and gaskets. The processing precision of rubber rods directly determines the performance and quality of the final sealing products. Rubber rods are usually made from rubber raw materials through extrusion molding. The initial form is a continuous long strip, which needs to be processed into short semi-finished products of a predetermined length through a cutting process before it can enter the subsequent hot pressing molding process.

[0003] Existing cutting devices lack a stable limiting and constraint structure for the tail of the rubber rod. During cutting, the worker holds one end of the rubber rod and pushes the other end towards the feed port of the cutting device. When the part of the rubber rod to be cut enters the cutting area and the blade contacts the rubber rod to cut, the part of the rubber rod that has not entered the tail of the cutting device (i.e., the part near the worker's hand) is in an unconstrained state. Because the rubber rod itself has a certain degree of flexibility, and the cutting blade generates radial impact force when it contacts the rubber rod at high speed, this impact force is transmitted to the tail of the rubber rod, causing irregular vibration at the tail. This tail vibration directly causes the part of the rubber rod to be cut to deviate from the preset cutting trajectory, resulting in a tilted cutting surface and excessive error in the length of the short rod, which seriously affects the processing quality of subsequent processes. Therefore, a rubber rod limiting device is proposed to assist in the cutting of the rubber rod. Utility Model Content

[0004] The purpose of this invention is to provide a rubber rod limiting device to solve the problem of irregular vibration occurring when the cutting device cuts the tail of the rubber rod.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber rod limiting device, comprising a platform, the top of which is provided with two parallel fixed ring discs, and multiple slots No. 1 are provided on the opposite side of the two fixed ring discs. An "L"-shaped movable rod is movably disposed inside each of the multiple slots No. 1. Multiple limiting plates are provided on both fixed ring discs, and the two ends of each limiting plate are respectively connected to the inner ends of the corresponding movable rods on the two fixed ring discs. A movable ring disc is rotatably disposed on the opposite side of the two fixed ring discs, and multiple arc-shaped grooves are provided on the movable ring discs. The ends of the multiple movable rods away from the limiting plates pass through the multiple arc-shaped grooves. The rotation of the movable ring discs, through the cooperation of the arc-shaped grooves and the movable rods, drives the movable rods to move radially along the slots No. 1, thereby causing the limiting plates to move closer to or away from the center position.

[0006] Furthermore, the three No. 1 slots are arranged symmetrically around the center of the fixed ring disk.

[0007] Furthermore, there are three limiting plates, and the included angle between any two limiting plates is set at 60 degrees.

[0008] Furthermore, the top of the platform is connected to two separate and parallel connecting blocks, the top of which is connected to the bottom of the fixed ring disk.

[0009] Furthermore, a vertical plate is connected to the top of the platform, and a fixing bolt is threaded onto the vertical plate. One end of the fixing bolt can tightly abut against the movable ring disc.

[0010] Furthermore, the fixing bolt is in the shape of an "I".

[0011] Furthermore, an anti-slip pad is provided at the end of the fixing bolt near the movable ring disc.

[0012] Furthermore, the sides of the plurality of limiting plates that are close to each other are arranged in an arc shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This rubber rod limiting device forms a double-support limiting area through two fixed ring discs at the top of the platform, and three limiting plates form a central limiting space. The tail of the rubber rod can be completely placed into the area formed by the three limiting plates. The inner wall of the limiting plate is evenly attached to the outer wall of the rubber rod, replacing the traditional unrestrained state and directly forming radial constraint on the tail, avoiding the problems of tail swing or axis torsion.

[0015] This rubber rod limiting device uses a linkage structure consisting of a fixed ring plate, a first groove, a movable ring plate, an arc groove, and a moving rod. Pulling or pushing a single limiting plate can cause the three limiting plates to move closer or further away simultaneously, thereby adjusting the size of the limiting space and adapting to rubber rods of different sizes.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-4 This utility model provides a rubber rod limiting device, including a platform 10. The top of the platform 10 is connected to two separate and parallel connecting blocks 110. Each of the two connecting blocks 110 is connected to a fixed ring disc 20. Three slots 201 are provided on the side of the two fixed ring discs 20 that are far apart from each other. The three slots 201 are symmetrically arranged around the center of the fixed ring discs 20. An "L"-shaped moving rod 210 is movably arranged inside the three slots 201. Three limiting plates 220 are provided in the inner ring of the two fixed ring discs 20. Both sides of the limiting plates 220 are connected to the moving rods 210. The included angle between every two limiting plates 220 is 60 degrees.

[0024] By controlling the three moving rods 210 to move closer or further apart from each other, the three moving rods 210 push or pull the three limiting plates 220 to move closer or further apart from each other, thereby adjusting the distance between the three limiting plates 220, and thus limiting the rubber rods of different thicknesses.

[0025] Two fixed ring discs 20 are each rotatably mounted on a movable ring disc 30 on one side away from each other. The movable ring disc 30 has three arc-shaped grooves 301. The ends of three moving rods 210 away from the limiting plate 220 pass through the three arc-shaped grooves 301 respectively. A vertical plate 120 is connected to the top of the platform 10. A fixing bolt 310 is threaded onto the vertical plate 120. The fixing bolt 310 is in the shape of an "I". One end of the fixing bolt 310 can tightly abut against the movable ring disc 30. The movable ring disc 30 is fixed by the fixing bolt 310, so that the movable ring disc 30 cannot rotate. Since the three moving rods 210 are limited by the three arc-shaped grooves 301, the limiting plate 220 cannot move under gravity, thereby maintaining the distance between the three limiting plates 220.

[0026] The side of the limiting plates 220 that are close to each other is set as an arc surface.

[0027] The fixed bolt 310 is provided with an anti-slip pad at one end near the movable ring 30. The anti-slip pad is made of nitrile rubber.

[0028] The working principle and usage process of this utility model are as follows: If the rubber rod to be limited is relatively thick, pull a single limiting plate 220 directly. The limiting plate 220 drives the "L"-shaped moving rods 210 connected on both sides. Since all three moving rods 210 pass through the arc groove 301 of the movable ring 30, the movement of a single moving rod 210 will cause the other two moving rods 210 to move synchronously, eventually causing the three limiting plates 220 to move away from each other until the distance can accommodate the rubber rod. If the rubber rod to be limited is relatively thin, push the three limiting plates 220 closer together. The limiting plates 220 drive the moving rods 210 to move along the first groove 201 towards the center of the fixed ring 20 until the distance between the three limiting plates 220 matches the thickness of the rubber rod.

[0029] After the spacing adjustment is completed, rotate the "I"-shaped fixing bolt 310 on the vertical plate 120 so that one end of the fixing bolt 310 is tightly against the movable ring plate 30, restricting the rotation of the movable ring plate 30. At this time, the moving rod 210 is limited by the arc groove 301, and the limiting plate 220 cannot move under the action of gravity or external force, thus maintaining the current spacing stability.

[0030] When using the rubber cutting rod, place the first rubber rod into the central area formed by the three limiting plates 220, ensuring that the outer wall of the rubber rod is evenly attached to the three limiting plates 220 for stable positioning. Then, place the second rubber rod to be cut into the limiting area, with one end of it attached to the other end of the first rubber rod. Push the second rubber rod, causing it to slowly move the first rubber rod forward along the limiting direction until the part of the first rubber rod to be cut is pushed into the cutting device. During this process, due to the limiting effect of the limiting plates 220, neither rubber rod will experience radial displacement, ensuring the accurate cutting position of the first rubber rod. Repeat the operation, with the rear rod pushing the front rod to cut.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
