Description

Technical Field

[0001] This utility model relates to the technical field of rubber material conveying equipment, and in particular to a heated pressure plate. Background Technology

[0002] Currently, the automotive industry commonly uses adhesive application processes in assembly, welding, and painting. During adhesive application, the cylinder of the adhesive pump drives the pressure plate downwards, forcing the adhesive from the glue tank towards the dispensing port. The adhesive is then discharged from the dispensing port and conveyed to the glue gun, which sprays the adhesive onto the workpiece. Because some adhesives have high viscosity and cannot be piped at room temperature and pressure, they require heating before delivery. Therefore, the pressure plate of the adhesive pump typically has a heating function to soften the adhesive in the upper layer of the glue tank and improve its flowability.

[0003] The pressure plate of existing glue pumps is generally a cast metal part with a built-in heating element during casting. The heating element is used to heat the pressure plate and then heat the glue. When the heating element fails during the operation of the glue pump, it cannot be removed because it is located inside the pressure plate. As a result, the pressure plate is scrapped due to insufficient heating power, and the entire pressure plate needs to be replaced, which leads to high maintenance costs for the glue pump.

[0004] Therefore, there is an urgent need for a heated pressing plate to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heating pressure plate that facilitates the replacement of the heating element.

[0006] To achieve this objective, the present invention adopts the following technical solution: A heating plate includes a plate body, a heating element, and an insulating plate.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0023] like Figures 1-4As shown, this embodiment provides a heating pressure plate, including a plate body 11, heating elements 12, and an insulating pressure plate 13. A fluid delivery channel 111 is provided inside the plate body 11, extending from the bottom to the top of the plate body 11. Multiple receiving slots 112 are provided on the top of the plate body 11. The heating elements 12 are correspondingly arranged in the receiving slots 112 and are inserted into the corresponding receiving slots 112. The insulating pressure plate 13 is detachably connected to the plate body 11, and the tops of the heating elements 12 abut against the insulating pressure plate 13.

[0024] The heating plate provided in this embodiment has a heating tube 12 for heating the adhesive material inserted into a receiving groove 112 at the top of the plate body 11. An insulating plate 13 presses against the top of the heating tube 12 to fix the heating tube 12 in the receiving groove 112. The insulating plate 13 is detachably connected to the plate body 11, so that when the heating tube 12 fails, the insulating plate 13 can be removed to remove and replace the faulty heating tube 12 without replacing the entire plate body 11, thus reducing the maintenance cost when the heating tube 12 fails.

[0025] Furthermore, such as Figures 2-4 As shown, a terminal 121 is provided at the top of the heating element 12, and a clearance hole 131 is provided on the insulating pressure plate 13, through which the terminal 121 passes. The heating element 12 is an electric heating element, and it needs to be energized when heating the adhesive. By providing a clearance hole 131 on the insulating pressure plate 13, the presence of the insulating pressure plate 13 is prevented from obstructing the connection between the power supply cable and the terminal 121 of the heating element 12. Electric heating elements (also called electric heating tubes) are existing products in this field, and their structure and principle will not be described in detail here.

[0026] Furthermore, such as Figure 2 As shown, multiple receiving slots 112 are spaced apart around the axis of the plate body 11 to improve the uniformity of heating of the plate body 11 by the heating tube 12.

[0027] Furthermore, such as Figure 2 and Figure 3 As shown, multiple insulating pressure plates 13 are provided, and the multiple insulating pressure plates 13 are spaced apart around the axis of the disk body 11. In this embodiment, the insulating pressure plates 13 are connected to the disk body 11 by screws. Compared with providing a single insulating pressure plate 13 to press against all heating tubes 12, providing multiple insulating pressure plates 13 facilitates the disassembly of the insulating pressure plates 13.

[0028] Furthermore, such as Figure 3 As shown, each insulating pressure plate 13 abuts against multiple heating tubes 12 to reduce the number of insulating pressure plates 13. In this embodiment, four insulating pressure plates 13 are provided.

[0029] Optionally, such as Figures 2-4As shown, a mounting groove 113 is provided on the top of the disc body 11, and the heating element 12 and the insulating pressure plate 13 are both located in the lower part of the mounting groove 113. By providing a mounting groove 113 on the top of the disc body 11, the overall height of the disc body 11 can be reduced.

[0030] Optionally, such as Figure 2 and Figure 2 As shown, the heating plate provided in this embodiment also includes heat insulation cotton 14 and a dust cover 15. The dust cover 15 is placed on top of the mounting groove 113 and is detachably connected to the plate body 11. The heat insulation cotton 14 is disposed inside the mounting groove 113 and is located between the insulating plate 13 and the dust cover 15. The heat insulation cotton 14 serves to insulate heat, and the dust cover 15 covers the mounting groove 113 to prevent dust and debris from entering the mounting groove 113. In this embodiment, the dust cover 15 is connected to the plate body 11 by screws. In this embodiment, multiple heat insulation cotton 14 and multiple dust covers 15 are provided, with multiple heat insulation cotton 14 arranged around the axis of the plate body 11, and multiple dust covers 15 also arranged around the axis of the plate body 11.

[0031] Optionally, such as Figure 1 As shown, this embodiment also includes a connector 16, which is connected to the dust cover 15, and all heating elements 12 are electrically connected to the connector 16. Specifically, the connector 16 and the heating elements 12 are connected by cables. When the heating plate is in use, an external power source can supply power to each heating element 12 through the connector 16.

[0032] Furthermore, the dust cover 15 is provided with a wire hole located below the connector 16. One end of the cable is connected to the connector 16, and the other end passes through the wire hole into the mounting groove 113, and extends through the gap between two adjacent heat insulation cotton 14 to the space between the heat insulation cotton 14 and the insulating pressure plate 13, and then passes through the clearance hole 131 on the insulating pressure plate 13 to connect with each heating tube 12.

[0033] Optionally, such as Figure 1 and Figure 2 As shown, this embodiment also includes a plurality of sealing rings 17 spaced apart along the height direction of the disc body 11. The sealing rings 17 are all sleeved on the outer periphery of the disc body 11 and are used to seal the gap between the disc body 11 and the inner wall of the adhesive storage container.

[0034] Furthermore, such as Figure 2 As shown, the outer periphery of the disc body 11 is provided with grooves corresponding to the sealing rings 17. The sealing rings 17 are fitted into the corresponding grooves, and part of them are exposed outside the corresponding grooves.

[0035] Optionally, such as Figure 1 , Figure 3 and Figure 4As shown, the top of the disc body 11 is provided with an exhaust pipe 18 and an air inlet pipe 19. The exhaust pipe 18 and the air inlet pipe 19 are respectively connected to the fluid delivery channel 111. A sealing rod 20 is inserted into the top of the exhaust pipe 18, and a switch valve 21 is provided on the air inlet pipe 19.

[0036] Furthermore, such as Figure 2 As shown, an air intake connector 22 is provided at the top of the air intake pipe 19 to facilitate connection between the air intake pipe 19 and an external air source.

[0037] The working process of this utility model is as follows: the sealing rod 20 is unscrewed from the exhaust pipe 18, so that the fluid delivery channel 111 is connected to the outside through the exhaust pipe 18. Power is supplied to each heating tube 12 through the connector 16, so that the heating tube 12 heats the plate body 11 and presses the heating plate into the storage container for storing the rubber. Since the exhaust pipe 18 is connected to the outside, the residual air between the heating plate and the storage container can be discharged to the outside. After the bottom surface of the heating plate is in contact with the surface of the fluid in the storage container and the residual air has been discharged, the sealing rod 20 is screwed back into the exhaust pipe 18 to seal the exhaust pipe 18 and prevent the outside air from entering. When changing the storage container, since there is a vacuum between the heating plate and the storage container, it is difficult to lift the heating plate directly. The air inlet pipe 19 is opened through the switch valve 21 to vent air between the heating plate and the storage container to balance the internal and external pressure, so that the heating plate can be lifted out of the storage container.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
