Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machines, and more specifically, to a tire tread vulcanizing machine and a vulcanizing system. Background Technology

[0002] Currently, four-column vulcanizing machines are commonly used for producing rubber products. They are simple in structure, practical, low in cost, and easy and quick to operate. Existing four-column vulcanizing machines are often used to produce rubber products such as sealing rings and gaskets. Their structure is simple, typically consisting of a base, upper heating plate, lower heating plate, columns, platform, and crossbeams. However, when producing complex and precision-shaped rubber products, insufficient clamping force and temperature control issues often result in vulcanized products that are either under-vulcanized, over-vulcanized, or under-vulcanized. Utility Model Content

[0003] The main purpose of this invention is to provide a tread vulcanizing machine and vulcanizing system to solve the problem of poor vulcanization quality in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a tire tread vulcanizing machine is provided, comprising: a base, a vulcanizing device, a lifting platform, a heating device, and a force-applying device. The vulcanizing device is disposed on the base and has a vulcanizing chamber for vulcanizing the tire tread. The lifting platform is vertically movable relative to the base. The upper cover of the vulcanizing device is connected to the lifting platform and can be placed above the vulcanizing chamber under the action of the lifting platform. At least a portion of the heating device is located below the lifting platform and moves up and down synchronously with the lifting platform. When the upper cover closes the vulcanizing chamber, the heating device heats the tire tread inside the vulcanizing chamber. The force-applying device is disposed above the lifting platform and applies force to the vulcanizing device when the lifting platform closes the vulcanizing chamber, so that the vulcanizing device has a predetermined clamping force.

[0005] Furthermore, the force-applying device includes a force-applying column and a force-applying drive component. The lifting platform has a force-applying hole, and the force-applying column can extend into the force-applying hole and apply force to the vulcanizing device through the force-applying hole. The force-applying column is connected to the output end of the force-applying drive component, and the force-applying drive component applies force to the force-applying column and provides a clamping force to the vulcanizing device through the force-applying column.

[0006] Furthermore, the force-applying drive member is arranged to move laterally relative to the lifting platform, and has a force-applying position located directly above the force-applying column and a clearance position located directly above the lifting platform. The force-applying device also includes a force-applying lateral movement drive member, which is drivenly connected to the force-applying drive member and drives the force-applying drive member to move between the force-applying position and the clearance position.

[0007] Furthermore, when in the force-applying position, both the force-applying column and the force-applying drive are located on the longitudinal central axis of the vulcanizing device.

[0008] Furthermore, the vulcanizing device includes a vulcanizing chamber, an inner mold, and an outer mold. The vulcanizing chamber has a vulcanizing cavity, the inner mold is disposed within the vulcanizing chamber, and the outer mold is movable relative to the inner mold.

[0009] Furthermore, the tread vulcanizing machine also includes a lifting drive and a top seat. The lifting drive is connected to the lifting platform and drives the lifting platform to move up and down. The top seat is located above the lifting platform and is connected to the base through a column. The lifting platform passes through the column, and the lifting drive is located on the top seat.

[0010] Furthermore, the force-applying device is connected to the lifting platform drive and drives the lifting platform to move up and down, and applies force to the vulcanizing device through the lifting platform.

[0011] Furthermore, the heating device includes a heating section and an electric heating mechanism. The heating section is located on the lower surface of the lifting platform and moves up and down synchronously with the lifting platform. The electric heating mechanism is connected to the heating section and provides the heating medium to the heating section and controls the heating state of the heating section.

[0012] Furthermore, the tread vulcanizing machine also includes an electrical control device, which is electrically connected to the force application device and controls the operation of the force application device.

[0013] According to another aspect of the present invention, a vulcanization system is provided, including the above-described tread vulcanizing machine.

[0014] By applying the technical solution of this utility model, the clamping force of the vulcanizing device is increased by setting up a force application device, thereby improving the vulcanization quality of the tire tread. Specifically, the tread vulcanizing machine of this embodiment opens and closes the vulcanizing device by the up and down movement of the lifting platform. In order to improve the clamping force, a force application device is added to ensure the clamping force of the vulcanizing device and thus ensure the vulcanization quality of the tire tread. On the other hand, a heating device is set up to control the temperature during the vulcanization process, thereby accurately providing the heat required for vulcanization. In this way, the clamping force of the vulcanizing device and the temperature during the vulcanization process can be guaranteed by the force application device and the heating device, thereby reducing problems such as uneven vulcanization, under-vulcanization or over-vulcanization caused by improper temperature and pressure control, thereby improving the vulcanization quality of the tire tread and making the tire tread quality stable and reliable.

[0025] To address the problem of poor vulcanization quality in existing technologies, this invention provides a tread vulcanizing machine and a vulcanization system, wherein the vulcanization system includes the tread vulcanizing machine described below.

[0026] Example 1

[0027] like Figure 1 , Figure 2The illustrated tire tread vulcanizing machine includes: a base 10, a vulcanizing device 20, a lifting platform 30, a heating device 40, and a force-applying device 50. The vulcanizing device 20 is mounted on the base 10 and has a vulcanizing chamber for vulcanizing the tire tread. The lifting platform 30 is vertically movable relative to the base 10. The upper cover of the vulcanizing device 20 is connected to the lifting platform 30 and can be placed over the vulcanizing chamber under the action of the lifting platform 30. At least a portion of the heating device 40 is located below the lifting platform 30 and moves up and down synchronously with the lifting platform 30. When the upper cover closes the vulcanizing chamber, the heating device 40 heats the tire tread inside the vulcanizing chamber. The force-applying device 50 is mounted above the lifting platform 30 and applies force to the vulcanizing device 20 when the lifting platform 30 closes the vulcanizing chamber, so that the vulcanizing device 20 has a predetermined clamping force.

[0028] This embodiment improves the vulcanization quality of the tread by setting up a force application device 50 to increase the clamping force of the vulcanizing device 20. Specifically, the vulcanizing machine in this embodiment opens and closes the vulcanizing device 20 by moving the lifting platform 30 up and down. To increase the clamping force, a force application device 50 is added to ensure the clamping force of the vulcanizing device 20 and thus ensure the vulcanization quality of the tread. On the other hand, a heating device 40 is set up to control the temperature during the vulcanization process, thereby accurately providing the heat required for vulcanization. In this way, the force application device 50 and the heating device 40 can ensure the clamping force of the vulcanizing device 20 and the temperature during the vulcanization process, thereby reducing problems such as uneven vulcanization, under-vulcanization or over-vulcanization caused by improper temperature and pressure control, thereby improving the vulcanization quality of the tread and making the tread quality stable and reliable.

[0029] It should be noted that, as Figure 1 As shown, the tread vulcanizing machine in this embodiment is configured with a multi-column structure. As the supporting structure of the tread vulcanizing machine, it has multiple spaced columns 100, and a top seat 70 and a base 10 arranged vertically. The lifting platform 30, vulcanizing device 20, heating device 40, and force application device 50 are all located between the top seat 70 and the base 10. In a top-to-bottom direction, the top seat 70, force application device 50, lifting platform 30, vulcanizing device 20, and base 10 are arranged sequentially. The heating device 40 is located between the lifting platform 30 and the base 10, and can be positioned above or around the vulcanizing device 20 for convenient heating. Depending on the actual situation, the tread vulcanizing machine can be configured with a three-column structure, a four-column structure, a five-column structure, etc. Figure 1 The tread vulcanizing machine shown is a four-column structure. The vertical direction in this embodiment is... Figure 1 The up and down directions in the middle.

[0030] In this embodiment, the force-applying device 50 includes a force-applying column 51 and a force-applying drive member 52. The lifting platform 30 has a force-applying hole, and the force-applying column 51 can extend into the force-applying hole and apply force to the vulcanizing device 20 through the force-applying hole. The force-applying column 51 is connected to the output end of the force-applying drive member 52. The force-applying drive member 52 applies force to the force-applying column 51 and provides a clamping force to the vulcanizing device 20 through the force-applying column 51. In this way, the output force of the force-applying drive member 52 is transmitted to the vulcanizing device 20 through the force-applying column 51, thereby ensuring that the vulcanizing device 20 has a predetermined clamping force, thereby improving the vulcanization quality of the tire tread. Specifically, the force-applying column 51 in this embodiment is set as a cylinder. Of course, depending on the actual situation, it can also be set as a prism, which does not affect the transmission. The lifting platform 30 is set as a plate, which can be a circular plate or a rectangular plate. In this embodiment, the lifting platform 30 is set as a rectangular plate. The force-applying drive component 52 is positioned above the force-applying column 51, with their central axes aligned. The end of the force-applying column 51 furthest from the force-applying drive component 52 is connected to the lifting platform 30. The lifting platform 30 may have a force-applying hole, allowing the force-applying column 51 to directly act on the vulcanizing device 20. Thus, when the force-applying drive component 52 applies a downward force to the force-applying column 51, the force-applying column 51 applies a mold-closing force to the vulcanizing device 20, thereby improving the mold-closing effect and thus improving the vulcanization quality. Simultaneously, when the lifting platform 30 rises, it can also remove the force-applying column 51 and the force-applying drive component 52 from their positions directly above the lifting platform 30, facilitating the rise of the lifting platform 30. Alternatively, the lifting platform 30 may not have a force-applying hole, allowing the force-applying column 51 to act directly on the lifting platform 30, transmitting the force to the vulcanizing device 20 through the lifting platform 30. Optionally, the force-applying drive component 52 may be a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder.

[0031] In this embodiment, the force-applying drive member 52 is laterally movable relative to the lifting platform 30, and has a force-applying position directly above the force-applying column 51 and a avoidance position directly above the lifting platform 30. The force-applying device 50 also includes a force-applying lateral movement drive member 53, which is drivenly connected to the force-applying drive member 52 and drives the force-applying drive member 52 to move between the force-applying position and the avoidance position. This allows the force-applying drive member 52 to both move downwards with the lifting platform 30 to apply a mold-closing force to the vulcanizing device 20 and avoid the position above the force-applying column 51, enabling the lifting platform 30 to drive the force-applying column 51 upwards. Specifically, the force-applying lateral movement drive member 53 can optionally be a hydraulic cylinder, pneumatic cylinder, electric cylinder, etc. The force-applying lateral movement drive member 53 can be disposed around the force-applying drive member 52, applying a horizontal force to the force-applying drive member 52, thereby allowing the force-applying drive member 52 to move closer to or further away from the position directly above the lifting platform 30. Depending on actual needs, the force-applying lateral movement drive 53 can be configured as one or more. When one force-applying lateral movement drive 53 is configured, when the force-applying drive 52 moves from the force-applying position to the avoidance position, the force-applying lateral movement drive 53 applies a pushing force, moving the force-applying drive 52 away from directly above the lifting platform 30; when the force-applying drive 52 moves from the avoidance position to the force-applying position, the force-applying lateral movement drive 53 applies a pulling force, moving the force-applying drive 52 closer to directly above the lifting platform 30. For example... Figure 2 As shown, this embodiment has two force-applying lateral movement drive units 53, symmetrically arranged around the force-applying drive unit 52. When a force is applied to the force-applying drive unit 52 near the top of the lifting platform 30, one force-applying lateral movement drive unit 53 applies a pushing force, pushing the force-applying drive unit 52 closer to the top of the lifting platform 30, while the other force-applying lateral movement drive unit 53 applies a pulling force, pulling the force-applying drive unit 52 closer to the top of the lifting platform 30. The two force-applying lateral movement drive units 53 act simultaneously, moving in opposite directions to apply a greater translational force to the force-applying drive unit 52. In this way, by controlling the lateral movement of the force-applying drive unit 52 through the force-applying lateral movement drive unit 53, the force-applying column 51 can be switched between the force-applying position and the avoidance position. This ensures the accuracy of the force-applying position without affecting the normal opening and closing of the lifting platform 30, thereby improving the flexibility and adaptability of the tire vulcanizing machine, and at the same time avoiding interference with other components when the force-applying column 51 rises. The force-applying column 51 can be connected to the force-applying drive component 52 by means of hooking or other means, so that when the force-applying drive component 52 moves between the force-applying position and the avoidance position, it can drive the force-applying column 51 to move simultaneously.

[0032] In this embodiment, when in the force application position, both the force application column 51 and the force application drive component 52 are located on the longitudinal central axis of the vulcanizing device 20, thereby improving the uniformity and consistency of the vulcanization effect and ensuring the vulcanization effect of the tire tread. Specifically, in this embodiment, the lifting platform 30 and the base 10 are vertically aligned, the force application column 51 is located at the center of the lifting platform 30, and the force application drive component 52 is vertically aligned with the force application column 51 when in the force application position. This ensures that the force application column 51 can act perpendicularly on the vulcanizing device 20 when applying force, avoiding uneven pressure distribution caused by improper force application angle, thus ensuring the vulcanization effect. On the other hand, the force of the force application column 51 acts on the center of the vulcanizing device 20, and the force spreads evenly to the surrounding area through the center, ensuring that the applied force acts evenly on the vulcanizing device 20, thereby ensuring the uniform action of the mold closing force, thus ensuring the mold closing effect and improving the vulcanization quality.

[0033] In this embodiment, the vulcanizing device 20 includes a vulcanizing chamber, an inner mold, and an outer mold. The vulcanizing chamber has a vulcanizing cavity. The inner mold is disposed inside the vulcanizing chamber, and the outer mold is movable relative to the inner mold, thereby realizing the opening and closing of the outer mold relative to the inner mold, which facilitates the demolding of the tire tread and improves the convenience and safety of removing the tire tread.

[0034] In this embodiment, the tread vulcanizing machine also includes a lifting drive component 60 and a top seat 70. The lifting drive component 60 is driven to connect with the lifting platform 30 and drives the lifting platform 30 to move up and down. The top seat 70 is located above the lifting platform 30 and is connected to the base 10 via a column 100. The lifting platform 30 passes through the column 100, and the lifting drive component 60 is located on the top seat 70. Thus, by utilizing the output force of the lifting drive component 60 and the structure of the column 100 and the top seat 70, the lifting platform 30 can move up and down, providing the necessary opening and closing operation for the vulcanizing process. Specifically, the top seat 70 is a rectangular plate and is vertically aligned with the lifting platform 30. The top seat 70 has a through hole, and the lifting drive component 60 passes through the through hole. When the vulcanizing device 20 needs to open or close, the lifting drive component 60 drives the lifting device to move up and down. Optionally, the lifting drive component 60 can be configured as a hydraulic cylinder. When the cylinder rod extends, the lifting drive component 60 drives the lifting platform 30 to descend, bringing the upper cover closer to the vulcanizing cavity, thus completing the mold closing action. When the cylinder rod retracts, the lifting drive component 60 drives the lifting platform 30 to rise, thereby raising the upper cover away from the vulcanizing cavity, thus completing the mold opening action. In this embodiment, two lifting drive components 60 are provided and symmetrically arranged on both sides of the top seat 70 to ensure that the lifting process of the lifting platform 30 can be carried out smoothly, thereby improving the opening and closing accuracy and safety of the vulcanizing device 20. Of course, the lifting drive component 60 can also be configured as an electric cylinder, pneumatic cylinder, or other driving forms, as long as it can drive the lifting platform 30 to rise and fall smoothly.

[0035] In this embodiment, the heating device 40 includes a heating section 41 and an electric heating mechanism 42. The heating section 41 is located on the lower surface of the lifting platform 30 and moves up and down synchronously with the lifting platform 30. The electric heating mechanism 42 is connected to the heating section 41 and provides a heating medium to the heating section 41 and controls the heating state of the heating section 41, thereby ensuring that uniform and stable heat is provided to the tread in the vulcanizing chamber, thus ensuring the vulcanization effect. The heating section 41 can be configured as a heating plate structure, integrated on the upper cover of the vulcanizing device 20, so as to facilitate heating by the electric heating mechanism 42 and ensure that the vulcanizing chamber is heated uniformly. Of course, the heating section 41 can also be evenly arranged along the circumference of the vulcanizing device 20, thereby providing a uniform heating state to the vulcanizing chamber, thereby improving the vulcanization quality of the tread and avoiding uneven local vulcanization.

[0036] In this embodiment, the tread vulcanizing machine also includes an electrical control device 80, which is electrically connected to the force application device 50 and controls the action of the force application device 50, thereby improving the mold opening and closing accuracy of the vulcanizing device 20 and thus improving the vulcanization quality of the tread. In this embodiment, the electrical control device 80 is electrically connected to the force application drive component 52. Thus, during the vulcanization process, the electrical control device 80 can promptly control the action of the force application device 50, thereby achieving precise and rapid action of the force application device 50, while ensuring uniform pressure distribution within the vulcanization chamber during mold opening and closing, reducing human error, and thus guaranteeing the vulcanization effect. In this embodiment, the electrical control device 80 is also electrically connected to the lifting drive component 60 and the force application lateral movement drive component 53, thereby facilitating the lifting operation of the lifting platform 30 and the lateral movement of the force application drive component 52. Of course, depending on the actual situation, the electrical control device 80 can also be electrically connected to other components. For example, the electrical control device 80 can also be connected to the vulcanization lateral movement drive component to improve operational convenience, and can also be connected to the electric heating mechanism 42 to improve heating convenience.

[0037] It should be noted that the connection between the top seat 70 and the column 100 can be secured with lock nuts. A lock nut is installed at each of the four corners of the top seat 70 where it connects to the column 100, to improve the structural stability of the entire tread vulcanizing machine. The vulcanizing device 20 can use an extruder to inject rubber material into the vulcanizing chamber, thereby improving the vulcanization quality of the tread and reducing the generation of bubbles, burrs, etc. Multiple support legs can be installed at the bottom of the base 10 to improve the stability of the tread vulcanizing machine.

[0038] The working process of the tread vulcanizing machine in this embodiment is as follows: The electronic control device 80 sends a signal to the lifting drive component 60, the cylinder rod of the lifting drive component 60 extends, the lifting platform 30 receives a downward thrust, the lifting platform 30 pushes the upper cover and heating part 41 to be subjected to force, the upper cover and heating part 41 push the inner mold and outer mold to be subjected to force; the electronic control device 80 sends a signal to the force application lateral drive component 53, the force application lateral drive component 53 drives the force application drive component 52 to move directly above the force application column 51, and is in the vulcanization state. The electronic control device 80 sends a signal to the force application drive component 52, the force application drive component 52 is activated, and applies a downward thrust to the force application column 51. After a certain thrust is reached, that is, the mold closing force is in place, the mold is closed, the extruder squeezes rubber into the vulcanizing device 20. After the rubber is filled, after the rubber cools for a period of time, the extruder is disengaged from the tread vulcanizing machine, the electric heating mechanism 42 receives a working signal, and provides a suitable temperature to the heating part 41, thereby making the vulcanizing chamber reach a suitable temperature and starting the vulcanization of the tread. After vulcanization, the internal mechanism of the vulcanizing device 20 is activated, the top cover is released, and a signal is given to the force-applying lateral drive component 53. The force-applying lateral drive component 53 moves the force-applying drive component 52 away from the top of the force-applying column 51, thereby creating upward space above the force-applying column 51. The electronic control device 80 gives a signal to the lifting drive component 60, and the cylinder rod of the lifting drive component 60 retracts, causing the lifting platform 30 to receive an upward pulling force. The top cover and the heating part 41 are also subjected to an upward pulling force along with the lifting platform 30, pulling the lifting platform 30 upward to a certain position. At the same time, the top cover is disengaged from the other parts of the vulcanizing device 20, and the outer mold is moved upward. Then the tread can be removed. After the tread is removed, it can be reset. One action is completed, and the tread vulcanizing machine is ready for the next action.

[0039] Example 2

[0040] like Figure 3 , Figure 4 As shown, unlike Embodiment 1, the force application device 50 in this embodiment does not include the force application column 51, but is set as a force application driving component. The setting position of the electronic control device 80 is also different from that in Embodiment 1. The electronic control device 80 in this embodiment is fixed on the top seat 70, while the electronic control device 80 in Embodiment 1 is fixed on the base. However, the function of the electronic control device 80 is the same in Embodiment 1 and Embodiment 2.

[0041] In this embodiment, the force-applying device 50 is driven to the lifting platform 30, and drives the lifting platform 30 to move up and down, applying force to the vulcanizing device 20 through the lifting platform 30. Specifically, the force-applying device 50 in this embodiment includes a force-applying driving component, which is disposed above the lifting platform 30. The bottom of the lifting platform 30 is provided with an electric heating mechanism 42 and the upper cover of the vulcanizing device 20. The force-applying driving component can drive the lifting platform 30 to simultaneously raise and lower the electric heating mechanism 42 and the upper cover of the vulcanizing device 20. Depending on actual needs, multiple force-applying driving components can be provided to provide sufficient mold-closing force to the lifting platform. In this embodiment, four force-applying driving components are provided and disposed at the four corners of the rectangular lifting platform 30, thereby providing a uniform mold-closing force to the lifting platform 30 and improving the mold-closing accuracy of the vulcanizing device 20. Optionally, the force-applying driving component can be a hydraulic cylinder.

[0042] In this embodiment, the electronic control device 80 is electrically connected to the force application device 50 and controls the action of the force application device 50, thereby improving the opening and closing accuracy of the vulcanizing device 20 and thus improving the vulcanization quality of the tire tread.

[0043] In this embodiment, when the cylinder rod of the force-applying drive component extends, it pushes the lifting platform 30 to move the electric heating mechanism 42 and the upper cover of the vulcanizing device 20 downwards. After the upper cover of the vulcanizing device 20 matches the inner and outer molds of the vulcanizing device 20, it becomes a complete vulcanizing device 20, and the mold is closed. The electronic control device 80 sends a signal to the force-applying drive component to continue applying force, and the extruder extrudes the rubber material into the vulcanizing chamber. After the rubber material cools, the extruder disengages from the tread vulcanizing machine and sends a working signal to the heating device 40, causing the vulcanizing device 20 to heat up rapidly to the required temperature, and the tread vulcanization begins. After vulcanization, the electronic control device 80 sends a signal to the force-applying drive component, causing the cylinder rod to retract and move the lifting platform 30, the electric heating mechanism 42, and the upper cover of the vulcanizing device 20 along the line. The upper cover of the vulcanizing device 20 separates from the other parts of the vulcanizing device 20 (i.e., the inner mold and the outer mold). The outer mold and the inner mold move relative to each other, and through manual and mechanical actions, the tire tread is separated from the outer mold and removed. The entire vulcanization process is then complete.

[0044] It should be noted that "multiple" in the above embodiments refers to at least two.

[0047] 2. By setting up a force application device, the clamping force of the vulcanizing device is increased, thereby improving the vulcanization quality of the tire tread;

[0048] 3. On the one hand, the vulcanizing device is opened and closed by the up and down movement of the lifting platform. In order to improve the clamping force, a clamping device is added to ensure the clamping force of the vulcanizing device and thus ensure the vulcanization quality of the tire tread. On the other hand, a heating device is set to control the temperature during the vulcanization process, thereby accurately providing the heat required for vulcanization.
