Description

Technical Field

[0001] This utility model belongs to the field of adhesive mixing technology, specifically an adhesive mixing device. Background Technology

[0002] In brake pad production, the adhesive coating process is an essential step. The adhesive, acting as a binder, needs to be thoroughly prepared, stirred, and transported before bonding to the product. The uniformity of the adhesive mixing directly affects the coating quality and the bonding strength between the brake pad and the substrate, thus impacting the brake pad's performance and safety. Incomplete mixing can lead to weak localized bonding or adhesive buildup, affecting the overall performance of the brake pad and production efficiency. Therefore, higher requirements are placed on the structural design of the adhesive mixing device.

[0003] Chinese utility model patent CN210252131U discloses a mortar mixing device, including a mixing tank, a microwave generator, a filter tank, a sealing cover, and a drive motor. A support frame is welded to the bottom of the mixing tank. Four microwave generators are installed on the inner wall of the middle of the mixing tank, with an angle of 90° between adjacent microwave generators. A filter tank is located at the center of the mixing tank, and a sealing cover is installed at the top of the mixing tank. A screw is hinged to the center of the sealing cover via a bearing. Stirring paddles are evenly spaced on the outer wall of the screw, and each stirring paddle has an evenly spaced overflow hole. A drive motor is fixed at the center of the top of the sealing cover, and a microcontroller is fixed to the left side of the top of the sealing cover. This mortar mixing device not only improves the mixing efficiency and quality of the adhesive, but also enhances the practicality of the mixing device. However, the patent uses a traditional screw and single stirring paddle method, which is prone to bottom sedimentation during mixing, affecting the uniformity of the adhesive mixing and hindering the production of brake pads.

The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-3 As shown in the embodiment of this utility model, a rubber mixing device includes a base 1, a pneumatic lifting component 2 is provided on the top of the base 1, the pneumatic lifting component 2 allows the mixing component 4 to be raised and lowered at any time, which is convenient for inserting or removing the mixing rod into the rubber bucket, and also facilitates cleaning and maintenance. A connecting seat 3 is provided on the pneumatic lifting component 2, and the mixing component 4 is provided below the connecting seat 3. The multi-tube structure of the mixing component 4 can generate circumferential turbulence and bottom overturning during the mixing process, effectively reducing sedimentation. A detection component 5 is provided on the mixing component 4, which is used to detect the height of the rubber liquid in the rubber bucket 6. The rubber bucket 6 is provided on the base 1. The pneumatic lifting component 2 drives the stirring component 4 to descend, and the stirring rod component 43 is inserted into the glue tank 6. The stirring component 4 and the stirring rod component 43 rotate, driving the main stirring tube 432 to stir at high speed in the glue tank 6. The glue is fully turned over. The detection component 5 monitors the glue level in the glue tank 6 in real time. When the glue level is lower than the set value, the control system drives the conveying pipe 411 to add new glue. After the stirring is completed, the pneumatic lifting component 2 rises, and the stirring rod component 43 is removed from the glue tank 6, making it easy to remove the glue or clean it. The stirring rod component 43 is formed by a composite stirring structure consisting of the main stirring rod 431, several main stirring tubes 432 and auxiliary stirring tubes 433. Compared with the traditional screw and single stirring paddle method, the stirring path is more complex, which can effectively reduce the bottom sedimentation phenomenon and improve the stirring uniformity of the glue, which is beneficial to the glue coating production of brake pads. By setting up the pneumatic lifting component 2, it is not only convenient to lift, maintain and clean the mixing component 4, but also the mixing component 4 can be quickly lifted and detached from the glue tank 6 when mixing is not required, so as to achieve effective separation of the mixing component and the glue. This design avoids the problem of the mixing component being soaked in the glue for a long time, causing solidification and adhesion. It also facilitates the replacement and cleaning of the glue tank 6, and improves the operational flexibility and maintenance convenience of the equipment.

[0027] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the pneumatic lifting assembly 2 includes a lifting cylinder 21. The telescopic end of the lifting cylinder 21 is fixedly connected to a mounting plate 22, and a connecting seat 3 is fixedly connected to the mounting plate 22. In practical applications, the lifting cylinder 21 is fixedly installed on the base, with its telescopic end facing downwards and screwed to the mounting plate 22. The connecting seat 3 is a reinforced steel structure. When compressed air is introduced into the lifting cylinder 21, the piston rod extends, driving the mounting plate 22 and the connecting seat 3 to move downwards, thereby pushing the stirring assembly 4 to descend and insert into the glue bucket 6. When the lifting cylinder 21 exhausts air in the reverse direction, the piston rod retracts, driving the stirring assembly 4 to rise and disengage from the glue bucket 6. In this way, the stirring assembly 4 can automatically rise and fall at different operating stages, which is convenient for both stirring and cleaning and replacing the glue bucket 6.

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the mounting plate 22 is detachably connected to the connector 3, which facilitates the removal of the connector 3.

[0029] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, the mixing assembly 4 includes a mounting plate 41, which is mounted on a connecting seat 3. A drive motor 42 is mounted on the mounting plate 41, and a stirring rod assembly 43 is fixedly connected to the output end of the drive motor 42. A detection assembly 5 is located on one side of the upper part of the mounting plate 41. In practical applications, the mounting plate 41 is fixed to the connecting seat 3 with bolts to ensure reliable connection with the pneumatic lifting assembly 2. The drive motor 42 is installed at the center of the mounting plate 41 with its output end facing downwards and is fixedly connected to the stirring rod assembly 43 via a coupling. The stirring rod assembly 43 is inserted into the glue tank 6 and can form a mixing effect of up-and-down tumbling and circumferential turbulence when rotating, avoiding local deposition of the glue. A detection assembly 5 is located on one side of the mounting plate 41, which is relatively close to the mixing area so that the immersion liquid level detector 52 can detect the liquid level in the glue tank 6 in real time. When the liquid level is lower than the preset value, the detection assembly 5 will feed the signal back to the control system. The control system can drive the conveying pipe 411 to stop drawing the mixed glue from the glue tank 6 and remind the staff to add more material.

[0030] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the stirring rod assembly 43 includes a stirring main rod 431, which is located at the output end of the drive motor 42. Several main stirring tubes 432 are arranged circumferentially below the stirring main rod 431. The stirring main rod 431 is a cylindrical metal rod, and its top is fixedly connected to the output end of the drive motor 42 through a coupling or flange to ensure concentric rotation. Several main stirring tubes 432 are evenly welded or screwed to the lower end of the stirring main rod 431. The main stirring tubes 432 are radially distributed relative to the main rod, and the number can be set to 3 to 6 according to the diameter of the glue tank 6 and the stirring intensity requirements. The length of the main stirring tubes 432 is designed to be 1 / 2 to 2 / 3 of the radius of the tank, so that it covers most of the area of ​​the glue tank 6 when rotating, ensuring sufficient stirring range. During operation, the drive motor 42 drives the stirring main rod 431 to rotate at high speed, and the main stirring tubes 432 rotate at the same time. The glue material in the glue tank 6 generates a composite flow in the radial, circumferential and axial directions, and the glue material is fully mixed.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 3As shown, several main stirring tubes 432 are provided between the main stirring rod 431 and the auxiliary stirring tubes 433. In practical applications, several main stirring tubes 432 are provided at the lower end of the main stirring rod 431 along the circumferential direction. The auxiliary stirring tubes 433 are fixedly installed at intervals between the main stirring tubes 432 and the main stirring rod 431. The auxiliary stirring tubes 433 can adopt a short rod structure, with a length less than half that of the main stirring tubes 432, and are used to stir the rubber material in the middle area. During the stirring process, the main stirring tubes 432 drive the material near the wall of the rubber bucket 6 to rotate, and the auxiliary stirring tubes 433 stir the material in the middle layer. The two cooperate with each other to cause the rubber material in the rubber bucket 6 to generate compound disturbance and tumbling within different radius ranges.

[0032] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the detection component 5 includes an installation pipe 51, which is mounted on the mounting plate 41 and positioned between the main stirring tube 432 and the main stirring rod 431. A submersible level detector 52 is installed at the bottom of the installation pipe 51. In practice, the installation pipe 51 is vertically mounted on the mounting plate 41, with the submersible level detector 52 fixed at its bottom. The installation pipe 51 is positioned in the area between the main stirring rod 431 and the main stirring tube 432. Precise arrangement ensures the detector probe avoids the rotation trajectory of the agitator. The submersible level detector 52 directly contacts the surface of the adhesive material inside the glue tank 6. The detection signal is transmitted to the control system via a wire inside the installation pipe 51. During the mixing process, the submersible level detector 52 monitors the adhesive material level in real time. When the level is lower than a preset value, the system automatically issues a material shortage signal, controlling the material conveying pipe 411 to stop supplying material and reminding the operator to add material to the glue tank 6.

[0033] In one specific embodiment, please refer to Figure 1 , Figure 2 and Figure 3As shown, a material conveying pipe 411 is provided below the mounting plate 41. The material conveying pipe 411 is located between the main stirring tube 432 and the main stirring rod 431. A telescopic hose 412 is connected to the upper part of the material conveying pipe 411. In specific applications, the material conveying pipe 411 is fixedly installed below the mounting plate 41, with its lower outlet facing the gap area between the main stirring rod 431 and the main stirring tube 432. The upper end of the material conveying pipe 411 is fixedly connected to the telescopic hose 412, and the other end of the telescopic hose 412 is connected to the outside. At the feed pump inlet, during the mixing process, when the detection component 5 detects that the liquid level is too low, the control system drives the feed pump to start. After the adhesive in the glue tank 6 is mixed, the adhesive enters the telescopic hose 412 through the conveying pipe 411 and finally enters the external glue coating equipment. The outlet of the conveying pipe 411 is close to the rotation area of ​​the main stirring tube 432. The newly entered adhesive is quickly dispersed under the turbulence of the stirring rod 431 and the main stirring tube 432, forming a uniform mixture with the material in the glue tank 6.

[0034] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, an alarm 7 is also installed on one side of the upper part of the mounting plate 41. In specific implementation, the alarm 7 is connected to components such as the liquid level detector and the stirring control module through electrical connection. Once the liquid level is detected to be too high or too low or the stirring is abnormal, the alarm 7 will be activated immediately and emit an audible and visual alarm signal. Since the alarm 7 is located on the upper side of the mounting plate 41, its signal can be easily detected by the operator, thereby achieving a long-distance visual and audible reminder effect, ensuring good safety protection during equipment operation, and can monitor the rubber liquid level in real time and issue audible and visual warnings when abnormal, avoiding abnormal mixing caused by insufficient or excessive material, and reminding the staff to add material.

[0035] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, several rubber positioning blocks 11 are also provided above the base 1. These rubber positioning blocks 11 are located on the outside of the glue bucket 6. In practice, the rubber positioning blocks 11 are evenly distributed around the upper surface of the base 1, allowing the glue bucket 6 to be circumferentially limited by multiple positioning points. When the glue bucket 6 is placed on the base 1, the rubber positioning blocks 11 will be in close contact with the outer wall of the glue bucket 6, thereby flexibly clamping and limiting its fixation. Due to the good elasticity of the rubber positioning blocks 11, they can undergo a certain deformation when the glue bucket 6 is put in or taken out, which not only ensures the convenience of installation and disassembly but also maintains the stable placement of the glue bucket 6, preventing shaking and tilting during stirring or conveying, and improving the reliability and service life of the equipment.

[0036] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
