Description

Technical Field

[0001] This utility model relates to the technical field of raw material mixing equipment, specifically a raw material mixing equipment for the production of wear-resistant and shock-absorbing pads. Background Technology

[0002] Wear-resistant shock-absorbing pads mainly serve to reduce vibration. The raw materials for wear-resistant shock-absorbing pads are usually granular. Before producing wear-resistant shock-absorbing pads, the raw materials need to be mixed, which requires the use of raw material mixing equipment.

[0003] A search revealed a patent, CN215654745U, which discloses a raw material mixing device for the production of wear-resistant and shock-absorbing pads. This device solves the problem of uneven mixing in traditional raw material mixing equipment for wear-resistant and shock-absorbing pads. The device includes a mixing tank with a feed inlet connected to the left side of the top of the tank. A cylinder is fixed to the top of the tank's inner cavity. This invention utilizes an adjustment mechanism to easily adjust the angle of the second movable plate. When the second movable plate and the first movable plate are at the same horizontal angle, the first and second movable plates, driven by a first motor, press the raw material downwards, causing it to rise through the gap between the mixing tank and the cylinder, and then be poured into the cylinder through a through-hole. This process stirs the raw material, ensuring uniform mixing. When the second movable plate tilts, the raw material at the top of the first and second movable plates falls, achieving repeated stirring and improving the uniformity of the mixture.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a method for mixing the raw materials of wear-resistant and shock-absorbing pads by moving the first and second movable plates up and down. However, in reality, some raw materials for wear-resistant and shock-absorbing pads are granular, such as rubber granules. When mixing granular wear-resistant and shock-absorbing pads, the mixing efficiency using the first and second movable plates in the aforementioned comparative document is slow, and the granular material at the bottom is difficult to mix. The overall mixing effect needs to be improved. Therefore, there is an urgent need in the art to improve the raw material mixing equipment for the production of wear-resistant and shock-absorbing pads, thereby overcoming the shortcomings of the prior art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a raw material mixing device for the production of wear-resistant and shock-absorbing pads, thereby improving the efficiency of raw material mixing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a raw material mixing device for the production of wear-resistant and shock-absorbing pads, comprising a support frame, a sealing groove in the upper part of the support frame, a conical mixing cylinder for mixing inside the sealing groove, the cavity inside the conical mixing cylinder being conical in shape with a wider upper part and a narrower lower part, a feeding port and a first drive motor in the upper part of the conical mixing cylinder, a rotating shaft extending into the conical mixing cylinder being fixedly installed at the output end of the first drive motor, a mixing frame adapted to the cavity inside the conical mixing cylinder being fixedly installed on the side of the rotating shaft, a main controller being provided on the side of the support frame, a discharge port communicating with the conical mixing cylinder being provided at the lower part of the support frame, and vibration units for vibrating the inside of the conical mixing cylinder being provided on opposite side walls inside the sealing groove.

[0008] Preferably, the vibration unit includes a second drive motor fixedly installed on the inner wall of the sealing groove, two symmetrical connecting plates on the side of the conical mixing cylinder, an eccentric cam fixedly installed at the output end of the second drive motor, an abutment plate adapted to the cam fixedly installed on one side of the connecting plate, a limit moving block fixedly installed at the end of the connecting plate away from the conical mixing cylinder, a limit sliding groove adapted to the limit moving block is opened on the opposite side wall of the sealing groove, and a shock absorber and a shock absorber spring located in the limit sliding groove are provided on the opposite side of the limit moving block.

[0009] Preferably, the lower side of the conical mixing cylinder is provided with an electromagnetic valve for opening and closing, and a flexible connecting pipe with elasticity is fixedly installed between the lower part of the conical mixing cylinder and the discharge port.

[0010] Preferably, the support frame is provided with an inlet pipe and an outlet pipe on its side, which are used to transport coolant.

[0011] Preferably, an installation ring is fixedly installed between the two connecting plates, and the installation ring is used to install the conical mixing cylinder.

[0012] Preferably, a connecting rod is fixedly installed between the mixing frame and the side of the rotating shaft.

[0013] Preferably, the number of mixing racks is two, and they are symmetrically fixedly installed on the side of the rotating shaft.

[0014] To address the shortcomings of existing technologies, this utility model provides a raw material mixing device for the production of wear-resistant and shock-absorbing pads, overcoming the deficiencies of existing technologies. The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting the inner cavity to be inverted cone shape, the first drive motor drives the mixing frame to rotate. Due to the centrifugal force, the raw material moves outward. The diameter of the cone mixing cylinder decreases from top to bottom, forming a gradient constraint space. The raw material located at the bottom of the cone mixing cylinder is pushed upward. Under the cone geometric constraint, the circumferential flow driven by centrifugal force is coupled with the wall reaction force to form a spiral upward flow state, which accelerates the mixing efficiency of the raw material. Moreover, no unmixed raw material remains at the bottom of the cone mixing cylinder, thus improving the mixing efficiency of the raw material.

[0016] 2. In this utility model, by setting a vibration unit to vibrate the conical mixing cylinder, the raw materials are prevented from sticking to the side of the conical mixing cylinder. In addition, the vibration can improve the mixing efficiency of the raw materials and can quickly output the mixed raw materials, preventing blockage during the output of the raw materials.

[0017] 3. In this utility model, an external pump body is used in conjunction with an inlet pipe to deliver coolant into the sealed groove. The coolant cools the raw materials during the mixing process, preventing spontaneous combustion of the wear-resistant and shock-absorbing pad raw materials during mixing and improving the safety of raw material mixing.

The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

[0026] 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.

[0027] Example 1

[0028] Please see Figures 1-5 A raw material mixing device for producing wear-resistant and shock-absorbing pads includes a support frame 1. The upper part of the support frame 1 is provided with a sealed groove 2. A conical mixing cylinder 3 for mixing is provided inside the sealed groove 2. The cavity inside the conical mixing cylinder 3 is conical in shape, wider at the top and narrower at the bottom. The upper part of the conical mixing cylinder 3 is provided with a feeding port 4 and a first drive motor 5. The output end of the first drive motor 5 is fixedly installed with a rotating shaft 6 extending into the conical mixing cylinder 3. A mixing frame 7 adapted to the cavity inside the conical mixing cylinder 3 is fixedly installed on the side of the rotating shaft 6. A main controller 8 is provided on the side of the support frame 1. The lower part of the support frame 1 is provided with a discharge port 9 communicating with the conical mixing cylinder 3. Vibration units 10 for vibrating the conical mixing cylinder 3 are provided on opposite side walls inside the sealed groove 2. An electromagnetic valve 20 for opening and closing is provided on the lower side of the conical mixing cylinder 3.

[0029] In this embodiment, the specific implementation method is as follows: When it is necessary to mix the granular raw materials of the wear-resistant and shock-absorbing pad, the feeding port 4 is opened to introduce the raw materials to be mixed into the conical mixing cylinder 3. The first drive motor 5 is turned on, and the output end of the first drive motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the mixing frame 7 to rotate. Due to the centrifugal force, the raw materials move outward. The diameter of the conical mixing cylinder 3 decreases from top to bottom, forming a gradient constraint space. The raw materials located at the bottom of the conical mixing cylinder 3 are pushed upward. Under the conical geometric constraint, the circumferential flow driven by centrifugal force is coupled with the wall reaction force, inducing the axial component of the Taylor-Couette flow, forming a spiral upward flow state, which accelerates the mixing efficiency of the raw materials. Moreover, no unmixed raw materials remain at the bottom of the conical mixing cylinder 3. After mixing, the solenoid valve 20 is opened to output the raw materials through the discharge port 9. Since the cavity inside the conical mixing cylinder 3 is inverted cone shape, it is convenient for the output of the raw materials.

[0030] Example 2

[0031] Please see Figure 2 and Figure 5 This embodiment includes the above embodiment, and further includes: the vibration unit 10 includes a second drive motor 12 fixedly installed on the inner side wall of the sealing groove 2, two symmetrical connecting plates 11 are provided on the side of the conical mixing cylinder 3, an eccentric cam 13 is fixedly installed on the output end of the second drive motor 12, an abutment plate 14 adapted to the cam 13 is fixedly installed on one side of the connecting plate 11, a limiting moving block 15 is fixedly installed on the end of the connecting plate 11 away from the conical mixing cylinder 3, a limiting sliding groove 16 adapted to the limiting moving block 15 is opened on the opposite side wall of the sealing groove 2, a shock absorber 17 and a shock absorber spring 18 located in the limiting sliding groove 16 are provided on the opposite side of the limiting moving block 15, and an elastic flexible connecting pipe 19 is fixedly installed between the lower part of the conical mixing cylinder 3 and the discharge port 9.

[0032] In this embodiment, the specific implementation method is as follows: When mixing raw materials, two vibration units 10 are turned on simultaneously. The second drive motor 12 starts and its output end drives the cam 13 to rotate. When the cam 13 rotates, its protrusion pushes the connecting plate 11 to move. The connecting plate 11 drives the limiting moving block 15 to slide in the limiting sliding groove 16. With the help of the shock absorber 17 and the shock absorber spring 18, the effect of vibration on the conical mixing cylinder 3 is achieved, which prevents the raw materials from sticking to the side of the conical mixing cylinder 3. In addition, the vibration can improve the efficiency of raw material mixing and can quickly output the mixed raw materials, preventing blockage during raw material output.

[0033] Example 3

[0034] Please see Figures 1-5This embodiment includes all the above embodiments, and further includes: the side of the support frame 1 is provided with an inlet pipe 21 and an outlet pipe 22, the inlet pipe 21 and the outlet pipe 22 are used to transport coolant, an installation ring 23 is fixedly installed between the two connecting plates 11, the installation ring 23 is used to install the conical mixing cylinder 3, a connecting rod 24 is fixedly installed between the side of the mixing frame 7 and the rotating shaft 6, and there are two mixing frames 7 which are symmetrically fixedly installed on the side of the rotating shaft 6.

[0035] In this embodiment, the following is a specific implementation method: When mixing the raw materials of the wear-resistant and shock-absorbing pads, coolant is supplied to the sealed groove 2 through an external pump body and an inlet pipe 21. Since many raw materials of the wear-resistant and shock-absorbing pads are flammable, they are prone to frictional high temperatures during high-speed mixing. Coolant is used to cool the raw materials during the mixing process to prevent spontaneous combustion of the raw materials during mixing, thereby improving the safety of the raw material mixing. It is worth noting that the sealed groove 2 is in a sealed state, the second drive motor 12 is a waterproof motor, and the coolant can be discharged through the outlet pipe 22. The mounting ring 23 is used to install the conical mixing cylinder 3, and the connecting rod 24 improves the connection strength of the mixing frame 7. Two mixing frames 7 are the best choice, as they can achieve the mixing effect without obstructing the upward movement of the raw materials below due to centrifugal force.

They are mature technologies and have been fully disclosed, so they will not be repeated in the instruction manual. All of the electrical products mentioned above are equipped with power cords, and they are electrically connected to the external main controller 8 and 220V phase voltage (or 380V line voltage) through the power cords.
