Description

Technical Field

[0001] This utility model relates to the field of hot press technology, and in particular, to an automatic multi-layer hot press with a braking system. Background Technology

[0002] Multi-layer hot presses are invaluable tools in the sheet metal processing industry, widely used in wood, plastic, and metal composite panels. They utilize the combination of high temperature and pressure to rapidly hot-press materials, significantly improving production efficiency. With their high efficiency, precision, and stable performance, multi-layer hot presses excel in large-scale production, meeting the processing needs of sheets of different materials and specifications, making them an indispensable piece of equipment in the sheet metal processing industry.

[0003] When the motor of a multi-layer hot press stops working, due to the inertia of motion, the motor's self-braking performance is often unable to support the braking of the motor spindle. This can easily cause abnormal alarms in the control electrical system and equipment shutdown, and may even lead to production accidents. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic multi-layer hot press with a braking system.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An automatic multi-layer hot press with a braking system includes a hot press body, a disc brake assembly on the body of the hot press body, the disc brake assembly being connected to the main shaft of the hot press body, a fluid source connected to the disc brake assembly, and an on / off valve in the flow path of the fluid source. The hot press body also has a sensor that can detect whether the actuator of the hot press body has been raised to the sensing position. The sensor, the on / off valve, and the main shaft motor of the hot press are electrically connected.

[0007] Preferably, the fluid source includes a gas storage tank and a gas pump connected to the gas storage tank.

[0008] Preferably, the on / off valve is a solenoid valve.

[0009] Preferably, the hot press body is provided with an airbag, the airbag is opposite to the actuating end of the hot press body, the airbag is connected to an air jet pipe, and the air jet pipe extends to be opposite to the braking component of the disc brake assembly.

[0010] Preferably, the jet pipe is equipped with a throttle valve.

[0011] Preferably, a cooling fan blade is rotatably mounted on the body of the hot press, located beside the disc brake assembly, and the cooling fan blade is opposite to the braking component of the disc brake assembly; a gear is mounted on the rotating shaft of the cooling fan blade, and a rack is mounted on the actuating end of the hot press body, the rack meshing with the gear.

[0012] Preferably, a torsion spring is also connected to the shaft of the cooling fan blades; during the lifting process of the actuating end of the hot press body, the teeth of the rack mesh with the gear; when the actuating end of the hot press body is in the sensing position, the teeth of the rack disengage from the gear.

[0013] Preferably, the teeth of the rack are spring-loaded, and the yield threshold of the spring is higher than the yield threshold of the torsion spring when it rotates in the forward direction.

[0014] The beneficial effects of this invention are as follows: By additionally installing a disc brake assembly on the main shaft of the hot press body, and using the upward lifting position of the actuator as the shutdown trigger for the main shaft motor, the opening and closing valve is simultaneously driven to open, allowing the disc brake assembly to brake the main shaft in a timely manner.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1 to 5 As shown, an automatic multi-layer hot press with a braking system includes a hot press body 1. For example, the hot press body 1 may include a machine body, on which a motor and an ejector end are provided. The ejector end is often plate-shaped and can be called an ejector plate 12. The motor is particularly preferably located at the top of the machine body, and a disc brake assembly 2 is preferably provided at the top of the machine body, and the disc brake assembly 2 is connected to the main shaft 11.

[0023] Specifically, the main shaft 11 is connected to the brake disc of the disc brake assembly 2. When the brake pads of the disc brake assembly 2 brake, the brake pads abut against the brake disc, thereby limiting the rotation of the main shaft 11 under the action of friction. Therefore, a fluid source 3 should also be connected to the disc brake assembly 2, and an on / off valve is provided in the flow path of the fluid source 3.

[0024] For the hot press body 1, a sensor (not shown) is also installed on its body. The sensor can monitor the ejection position of the ejector plate 12, especially whether the ejector plate 12 has been raised to the sensing position. When the sensor detects that the ejector plate 12 has been raised to the sensing position, the controller of the hot press body 1 can control the motor to stop. At this time, the opening and closing valve will also open simultaneously, and the fluid source 3 will pump high-pressure fluid into the disc brake assembly 2. The main shaft 11 will immediately lock and prevent slippage.

[0025] In a specific example, the fluid source 3 may include an air tank 4 and an air pump connected to the air tank 4, while the on / off valve may be a solenoid valve. Both the air pump and the solenoid valve have the advantages of fast response and high degree of automation, making the braking system of the hot press easier to control and more responsive.

[0026] Hot presses require heating and pressurization during operation and are typically equipped with heating elements and hydraulic systems. These elements generate a significant amount of heat during operation, leading to an increase in the ambient temperature near the hot press. Furthermore, the braking performance of the disc brake assembly 2 depends to some extent on the heat dissipation performance of the brake discs. Therefore, the heat dissipation requirements for the disc brake assembly 2 are further increased when operating in a hot press environment.

[0027] In some embodiments, an airbag 6 is provided on the body, and the airbag 6 is positioned opposite the ejector plate 12. Furthermore, an air jet pipe 7 is connected to the airbag 6, the end of which extends to face the braking components (e.g., brake disc and brake pads) of the disc brake assembly 2. After the hot press completes the hot pressing operation and controls the ejector plate 12 to rise, the inflated airbag 6 is compressed, and the gas inside the airbag 6 is then sprayed towards the braking components to assist in heat dissipation. In a preferred example, a throttle valve is also provided inside the air jet pipe 7, which allows the gas inside the airbag 6 to flow out slowly. Especially after the braking components have finished braking the spindle 11, the air jet pipe 7 can still spray gas to dissipate heat, resulting in better heat dissipation.

[0028] As an alternative, a cooling fan blade 8 is rotatably mounted on the side of the braking component on the fuselage, and a gear 9 is mounted on the shaft of the cooling fan blade 8, while a rack 10 is mounted on the ejector plate 12. During the lifting of the ejector plate 12, the rack 10 drives the gear 9 to rotate, allowing the cooling fan blade 8 to blow airflow to assist in cooling the braking component.

[0029] In a preferred example, a torsion spring (not shown) is also connected to the shaft of the cooling fan blade 8. At this time, the lifting process of the ejector plate 12 becomes the energy storage process of the torsion spring. When the lifting plate is raised to the sensing position, the tooth 13 on the rack 10 will disengage from the gear 9, thus releasing the torsion spring. At the same time, the braking component has braked the main shaft 11, thereby realizing the heat dissipation of the cooling fan blade 8 after the braking component has performed the braking action.

[0030] For example, the aforementioned tooth 13 is preferably adapted to spring, and the yield threshold of the spring is adapted to be higher than the yield threshold of the torsion spring when it rotates in the forward direction. That is, during the lifting of the ejector plate 12, the torsion spring is easily pushed by the rack 10 to rotate in the forward direction and enter the energy storage state, while the spring maintains the support state for the tooth 13, so that the meshing of the rack 10 and the gear 9 can proceed smoothly; when the ejector plate 12 is ejected again, the torsion spring has reset and driven the cooling fan blade 8 to complete the rotation. At this time, the rack 10 will be in the opposite direction to the driving direction of the torsion spring, that is, the torsion spring is not easy to twist, so the spring will enter the yield state, and the tooth 13 will spring, so that the rack 10 can pass smoothly through the gear 9 without easily getting stuck.

[0031] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
