Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for vulcanizing machine processing, specifically a clamping mechanism for a vulcanizing machine. Background Technology

[0002] A vulcanizing machine is an industrial device used to vulcanize polymer materials such as rubber and plastics. By heating, pressurizing, and controlling the vulcanization time, it promotes the cross-linking of the material's molecular chains, thereby improving its strength, elasticity, wear resistance, and other properties. It is widely used in the production of tires, conveyor belts, seals, and other products. By using mechanical force to fix the mold or material, displacement or deformation caused by high temperature and high pressure during the vulcanization process can be prevented.

[0003] The existing technology has the following shortcomings: The existing technology, "A clamping mechanism for a vulcanizing machine" published with the publication number CN221937313U, "includes: a vulcanizing machine table, and a clamping limiting platform is installed above the vulcanizing machine table; it also includes: a movable adjustment port, which is disposed on the outer wall of the clamping limiting platform, and there are four of them. Slide rails are installed on both sides of the inner wall of the movable adjustment port. A driven slider is installed above the slide rails. A second electric cylinder is installed at the rear end of the driven slider. The second electric cylinder includes a second piston rod. A clamping limiting plate is installed at one end of the second piston rod, and the second electric cylinder is connected to the clamping limiting plate through the second piston rod."

[0004] The aforementioned device solves the problem of inconvenient manual adjustment by incorporating a slide rail, a second piston rod, and a clamping limit plate. However, this structure uses a traditional directional rigid clamping method to clamp the vulcanized material. The clamping mechanism cannot adapt to the vulcanized material and is prone to damaging the vulcanized material to be processed. Utility Model Content

[0010] As a preferred technical solution of this utility model, the main support also includes a sliding groove and side supports. The sliding groove is opened at the top of the main support, and two sets of side supports are provided and welded to the left and right sides of the main support.

[0011] As a preferred technical solution of this utility model, the lateral limiting frame further includes a limiting slider, an adaptive turntable, a connecting shaft, an extension bracket, and a guide wheel. The limiting slider is inserted into the bottom end of the lateral limiting frame, and the adaptive turntable is movably connected to the bottom of the lateral limiting frame through the connecting shaft.

[0015] Compared with the prior art, this utility model provides a clamping mechanism for a vulcanizing machine, which has the following features:

[0016] Beneficial effects:

[0017] A clamping mechanism for a vulcanizing machine comprises a central limiting frame, lateral limiting frames, an adaptive turntable, a connecting shaft, and guide wheels. In use, this structure is mounted on the upper part of the vulcanizing machine's heating plate. When the vulcanizing material is being vulcanized, it is inserted into the bottom side of the main support. Then, an electric cylinder is activated, pulling the lateral limiting frame via a piston push rod. The lateral limiting frame moves towards the center of the main support via a limiting slider connected to a sliding groove. During this process, the lateral limiting frame on that side presses against the adjusting rod on that side. After being pressed by the adjusting rod, the central limiting frame rotates under the support of the central shaft, simultaneously driving the adjusting rod on the other side, causing it to pull the lateral limiting frame synchronously towards the center of the main support. This continues until the guide wheels contact the outer side of the vulcanizing material, positioning it according to the corner positions of the rectangular material. After the guide wheels touch the vulcanizing material, the adaptive turntable rotates under the support of the connecting shaft until it clamps the four corners of the rectangular vulcanizing material.

[0018] Through the above settings and processes, the structure can adaptively position itself according to the corners of the rectangular vulcanized material during use. By cooperating with the guide wheel, connecting shaft and adaptive turntable, flexible positioning clamping is used instead of the commonly used directional clamping, reducing wear on the vulcanized material during clamping and thus improving processing quality.

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.

[0025] In this embodiment: a clamping mechanism for a vulcanizing machine includes a main support 1, an electric cylinder 2 and a piston rod 3. The electric cylinder 2 is disposed on the top of the main support 1, and the piston rod 3 is disposed on the side end of the electric cylinder 2.

[0026] A central limiting frame 4 is provided at the upper middle part of the main support 1, and a lateral limiting frame 5 is provided at the upper end of the main support 1.

[0027] The central limiting frame 4 also includes a central shaft 401 and an adjusting rod 402. The central shaft 401 passes through the middle of the central limiting frame 4 and is movably connected to the upper end of the main support 1. The two ends of the adjusting rod 402 are movably connected to the lateral limiting frame 5 and the central limiting frame 4, respectively.

[0028] In this embodiment, two sets of adjusting rod 402 and lateral limiting frame 5 are provided, and the two ends of adjusting rod 402 that are connected to lateral limiting frame 5 and central limiting frame 4 are provided with shaft structure passing through them and are movably connected to them; the main support 1 also includes slide groove 101 and side support 102. Slide groove 101 is opened at the top of the main support 1, and two sets of side support 102 are provided and welded to the left and right sides of the main support 1.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the adjusting linkage 402 is connected to the two lateral limiting frames 5 on both sides from the two ends of the central limiting frame 4, and the movement of one lateral limiting frame 5 drives the other lateral limiting frame 5, ensuring the continuity of their linkage.

[0030] In this embodiment, the lateral limiting frame 5 also includes a limiting slider 501, an adaptive turntable 502, a connecting shaft 503, an extension bracket 504, and a guide wheel 505. The limiting slider 501 is inserted into the bottom end of the lateral limiting frame 5, and the adaptive turntable 502 is movably connected to the bottom of the lateral limiting frame 5 through the connecting shaft 503. The connecting shaft 503 is movably connected to the bottom end of the lateral limiting frame 5 in a vertical posture. The extension bracket 504 is fixedly installed on the periphery of the adaptive turntable 502, and the guide wheel 505 is movably connected to the end of the extension bracket 504 through the central shaft.

[0031] Specifically, such as Figure 2 and Figure 3 As shown, when the guide wheel 505 contacts the corner of the rectangular vulcanized material, the two sets of extended brackets 504 with the included angle shape and the guide wheel 505 adjust the corner of the rectangular vulcanized material to a position of 45°.

[0032] In this embodiment, two sets of extension brackets 504 and guide wheels 505 are provided around each set of adaptive turntables 502, and there is a preset 90° included angle between them; two sets of limiting sliders 501 are provided at the bottom of each set of lateral limiting frames 5, and their positions are distributed corresponding to the slide grooves 101, and a sliding connection relationship is established with the slide grooves 101.

[0033] The working principle and usage process of this utility model are as follows: When using this structure, it is installed on the upper end of the heating plate of the vulcanizing machine. When the vulcanizing material is vulcanized, it is inserted into the bottom side of the main support 1. Then, the electric cylinder 2 is started, and the electric cylinder 2 pulls the lateral limiting frame 5 through the piston push rod 3. The lateral limiting frame 5 moves towards the middle of the main support 1 through the connection between the limiting slider 501 and the slide groove 101. During this process, the lateral limiting frame 5 on this side squeezes the adjusting connecting rod 402 on this side. After being squeezed by the adjusting connecting rod 402, the middle limiting frame 4 rotates through the support of the middle shaft 401, and at the same time drives the other side adjusting connecting rod 402, so that the other side adjusting connecting rod 402 pulls the lateral limiting frame 5 to move synchronously towards the middle of the main support 1. The guide wheel 505 is positioned according to the corner position of the rectangular material after it contacts the outer side of the vulcanized material. After the guide wheel 505 touches the vulcanized material, the adaptive turntable 502 rotates under the support of the connecting shaft 503 until it is clamped at the four corners of the rectangular vulcanized material.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
