Description

Technical Field

[0001] This utility model belongs to the field of vulcanizing machine technology, and specifically relates to a multi-channel temperature control device for the central mechanism of a vulcanizing machine. Background Technology

[0002] Existing multi-channel temperature control devices in the central mechanism of vulcanizing machines typically employ a serpentine tube heating structure, designed to improve heating efficiency by increasing the heat conduction path. However, due to the inherent bending structure of the serpentine tube, uneven temperature distribution on the flat surface is easily caused in practical applications. This phenomenon mainly stems from the obstruction of heat transfer in the bending area, forming regions with high local thermal resistance, thus causing temperature gradient differences and even obvious temperature dead zones.

[0003] Conventional methods include optimizing the bending radius and layout of the serpentine tube, adding heat-conducting materials, or improving the fluid circulation method. However, these methods are often limited by equipment space and manufacturing costs. For example, excessively reducing the bending radius may lead to increased fluid resistance, affecting the flow of the heating medium; while adding heat-conducting materials can improve heat transfer, it may also reduce the response speed and increase energy consumption. Therefore, we hope to design a multi-channel temperature control device with a novel structure for the central mechanism of a vulcanizing machine to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-channel temperature control device for the central mechanism of a vulcanizing machine, so as to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a multi-channel temperature control device for the central mechanism of a vulcanizing machine, comprising: a heating plate, the heating plate being fixed on the upper side of a heating component and sealed thereto, and a heat insulation plate being fixed at the lower end of the heating component for intercepting and isolating the heat radiated by the heating component;

[0006] The heating assembly includes a base frame, a heat medium inlet pipe for the heat medium to enter is fixed on the front side of the base frame, and a heat medium outlet pipe for the heat medium to exit is installed at the bottom of the base frame.

[0007] In a preferred embodiment, the bottom front side of the heat insulation plate is recessed downward to form an embedding groove. The depth of the embedding groove is less than the thickness of the heat insulation plate, and the front end of the embedding groove extends forward through the front end of the heat insulation plate. The cross-sectional dimensions and structure of the embedding groove are matched with the cross-sectional dimensions and structure of the heat medium discharge pipe. The upper rear side of the heat medium discharge pipe is provided with a connection hole for communicating with the inside of the box. In actual use, the front end of the heat medium discharge pipe is connected to the heat medium supply equipment recovery end, which can realize resource recycling and reuse.

[0008] In a preferred embodiment, the bottom frame includes a box body, the sum of the length of the box body in the front-back direction and the length of the heat medium inlet pipe in the front-back direction is the same as the length of the heat insulation plate in the front-back direction, and the length of the heat insulation plate in the front-back direction is the same as the length of the heating plate in the front-back direction.

[0009] In a preferred embodiment, the width of the box body in the left-right direction is the same as the width of the heat medium inlet pipe, the heat insulation plate, and the heating plate in the left-right direction.

[0010] In a preferred embodiment, the box body has a hollow interior and is equipped with spiral partitions welded inside to divide the internal space.

[0011] In a preferred embodiment, the spiral partition is arranged in a U-shaped spiral structure to divide the internal space of the box into a conveying channel for transporting the heat medium. The conveying channel is in a U-shaped spiral structure. By using the spiral partition to divide the internal space of the box into a U-shaped spiral conveying channel, the heat medium can run in a U-shaped spiral structure inside the box. Its discharge end is in the middle of the box. This arrangement can avoid the problem of large temperature difference between the inlet and the connecting hole, so that the temperature on the heating plate is uniform.

[0012] In a preferred embodiment, the end of the conveying channel is located in the middle of the box body, and a through hole is formed in the middle of the bottom of the box body, which is connected to the end of the conveying channel. The beginning of the conveying channel is located on the right front side of the box body, and an inlet is formed in the right front side of the box body for the heat medium to enter the conveying channel. In actual use, a guide arc plate can be welded at the turning point of the conveying channel to reduce the possibility of the heat medium generating eddies and make its flow smoother. The size of the guide arc plate can be set according to the size of the turning point of the conveying channel.

[0013] In a preferred embodiment, an inlet hole is provided in the middle of the front side of the heat medium inlet pipe for the heat medium to enter the heat medium inlet pipe. The right side of the heat medium inlet pipe is hollow, and its right rear side is connected to the inside of the box through an inlet.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are: 1. By setting the heating component and the conveying channel having a spiral structure, the heat medium can run in the box according to the spiral structure, which replaces the solution of heating with a serpentine bend, and solves the problem that the excessive reduction of the bending radius of the bend in the existing improved solution may lead to increased fluid resistance and affect the flow of the heating medium.

[0015] 2. By setting up a heat medium discharge pipe and embedding it in the heat insulation plate, and placing the discharge end of the conveying channel in the middle of the box, heat can be evenly distributed inside the box. The narrow width of the spiral baffle does not affect the mutual radiation of temperature and can also support the heating plate. This arrangement can avoid the problem of large temperature difference between the inlet and the connecting hole, so that the temperature on the heating plate is in a uniform state. The heat medium discharge pipe installed on the heat insulation plate can prevent excessive temperature leakage and reduce heat recovery, which is conducive to heat recovery.

[0024] 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.

[0025] As the first embodiment of this utility model:

[0026] Please see Figures 1 to 4 A multi-channel temperature control device for the central mechanism of a vulcanizing machine includes: a heating plate 300, which is fixed on the upper side of a heating component 200 and sealed thereto, and a heat insulation plate 100 is fixed at the lower end of the heating component 200 to intercept and isolate the heat radiated by the heating component 200.

[0027] The heating assembly 200 includes a base frame 210, a heat medium inlet pipe 230 for heat medium entry is fixed on the front side of the base frame 210, and a heat medium outlet pipe 220 for heat medium exit is installed at the bottom of the base frame 210.

[0028] The bottom front side of the heat insulation plate 100 is recessed downward to form an embedding groove 110. The depth of the embedding groove 110 is less than the thickness of the heat insulation plate 100, and the front end of the embedding groove 110 extends forward through the front end of the heat insulation plate 100. The cross-sectional dimensions and structure of the embedding groove 110 are matched with the cross-sectional dimensions and structure of the heat medium discharge pipe 220. The upper rear side of the heat medium discharge pipe 220 is provided with a connection hole for communicating with the inside of the box 211. In actual use, the front end of the heat medium discharge pipe 220 is connected to the heat medium supply equipment recovery end, which can realize resource recycling and reuse.

[0029] The bottom frame 210 includes a box body 211. The sum of the length of the box body 211 in the front-back direction and the length of the heat medium inlet pipe 230 in the front-back direction is the same as the length of the heat insulation plate 100 in the front-back direction. The length of the heat insulation plate 100 in the front-back direction is the same as the length of the heating plate 300 in the front-back direction.

[0030] The width of the box 211 in the left-right direction is the same as the width of the heat medium inlet pipe 230, the heat insulation plate 100 and the heating plate 300 in the left-right direction.

[0031] Specifically, by setting up the heating component 200, in actual use, the heat medium enters the starting position of the conveying channel 213 through the heat medium inlet pipe 230 and the inlet 215 on the right front side of the box 211. Since the spiral baffle 212 is set in a U-shaped spiral structure and divides the internal space of the box 211 into a U-shaped spiral structure to form the conveying channel 213 for conveying the heat medium, the conveying channel 213 is in a U-shaped spiral structure, which enables the heat medium to run in the box 211 in a U-shaped spiral structure, replacing the solution of using a serpentine bend for heating. This solves the problem that the excessive reduction of the bending radius of the bend in the existing improved solution may lead to increased fluid resistance and affect the flow of the heating medium.

[0032] As a second embodiment of this utility model:

[0033] Please see Figures 1 to 4 The box 211 has a hollow interior and is welded with spiral partitions 212 to divide the interior space of the box 211.

[0034] The spiral baffle 212 is arranged in a U-shaped spiral structure to divide the internal space of the box 211 into a U-shaped spiral structure to form a conveying channel 213 for conveying the heat medium. The conveying channel 213 is in a U-shaped spiral structure. By using the spiral baffle 212 to divide the internal space of the box 211 into a U-shaped spiral conveying channel 213, the heat medium can run in the U-shaped spiral structure inside the box 211. Its discharge end is in the middle of the box 211. This arrangement can avoid the problem of large temperature difference between the inlet 215 and the connecting hole 214, so that the temperature on the heating plate 300 is in a uniform state.

[0035] The end of the conveying channel 213 is located in the middle of the box 211. A connecting hole 214 is formed by penetrating downward from the bottom center of the box 211. The connecting hole 214 is connected to the end of the conveying channel 213. The starting end of the conveying channel 213 is located on the right front side of the box 211. An inlet 215 is formed by penetrating backward from the right front side of the box 211 for the heat medium to enter the conveying channel 213. In actual use, a guide arc plate can be welded at the turning position of the conveying channel 213 to reduce the possibility of the heat medium generating eddies and make its flow smoother. The size of the guide arc plate can be set according to the size of the turning position of the conveying channel 213.

[0036] The front middle of the heat medium inlet pipe 230 is provided with an inlet through hole for the heat medium to enter the heat medium inlet pipe 230. The right side of the heat medium inlet pipe 230 is hollow, and its right rear side is connected to the inside of the box body 211 through the inlet 215.

[0037] Based on the first embodiment described above, further, by setting a heat medium discharge pipe 220 and embedding it in the heat insulation plate 100, and setting the discharge end of the conveying channel 213 in the middle of the box 211, heat can be evenly distributed inside the box 211. The spiral partition 212, with its narrow width, will not affect the mutual radiation of temperature and can also support the heating plate 300. This arrangement can avoid the problem of a large temperature difference between the inlet 215 and the connecting hole 214, so that the temperature on the heating plate 300 is in a uniform state. The heat medium discharge pipe 220 installed on the heat insulation plate 100 can prevent excessive temperature leakage and reduce heat recovery, which is conducive to heat recovery.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
