Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, specifically to a manufacturing equipment for rubber processing. Background Technology

[0002] Further crushing of rubber raw material particles is a key pretreatment step in rubber processing. It aims to reduce particle size and improve material uniformity to meet the fineness requirements of different processes. Preheating rubber particles can improve the crushing effect.

[0003] A search revealed that patent application number 202421009988.3 discloses a rubber crushing device for rubber processing, relating to the field of rubber processing technology. The device includes a crushing chamber and a preheating feeding pipe. An installation plate is fixedly mounted on the top of the crushing chamber, and the preheating feeding pipe is fixedly mounted on the top of the installation plate. A heating plate is fixedly mounted on one side of the inner wall of the preheating feeding pipe, and a retention control component is installed inside the other side of the preheating feeding pipe. The crushing chamber contains a crushing structure, and a discharge port is opened at the bottom of the crushing chamber. The retention control component includes a first hydraulic cylinder, a first control plate, a second hydraulic cylinder, and a second control plate. Both the first and second hydraulic cylinders are fixedly mounted on one side of the preheating feeding pipe.

[0004] Although the rubber crushing device for rubber processing can increase the residence time of rubber material in the preheating feeding tube through the retention control component, and can heat the preheating feeding tube in conjunction with the heating plate, thus ensuring a good preheating effect on the rubber material and thus a good crushing effect, the heating plate of the rubber crushing device for rubber processing is located on one side of the preheating feeding tube. The rubber particles themselves have poor fluidity and high bulk density, which can easily lead to local blockage or uneven flow rate in the feeding tube. This can easily cause some particles to carbonize and stick together due to excessive heating, while other particles cannot reach the ideal softening state due to insufficient temperature, ultimately seriously affecting the efficiency and quality of subsequent crushing processes.

[0005] Therefore, we propose a manufacturing equipment for rubber processing. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a manufacturing equipment for rubber processing, which solves the problem that in existing devices, the heating plate is located on one side of the preheating feeding pipe, resulting in poor flowability of rubber raw material particles inside the preheating feeding pipe, which easily leads to uneven heating and makes it difficult to ensure the crushing effect of rubber raw material particles.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a manufacturing equipment for rubber processing, including a crushing box, wherein a crushing structure is provided inside the crushing box, and an installation plate is fixedly installed on the top surface of the crushing box;

[0008] The crushing structure has been described in detail in the referenced document and is existing technology, so it will not be repeated here.

[0009] A connecting pipe is fixedly installed in the middle of the top surface of the mounting plate, and a preheating feeding assembly is provided above the connecting pipe;

[0010] The preheating and feeding assembly includes a feeding box, a preheating pipe, and a flow pipe. The preheating pipe is fixedly installed in the middle of the top surface of the connecting pipe. Flow pipes are provided on both the left and right sides of the preheating pipe. A feeding hopper is fixedly installed at the bottom end of the flow pipe. The bottom end of the feeding hopper is arc-shaped and fixedly installed on the side wall at the bottom end of the preheating pipe. The top ends of the preheating pipe and the flow pipe are fixedly installed on the bottom surface of the feeding box. An electric heating tube and a spiral blade are provided inside the preheating pipe.

[0011] Preferably, a horizontal plate is fixedly installed in the middle of the top surface of the feeding box, and a motor is fixedly installed in the middle of the top surface of the horizontal plate. The output end of the motor is fixedly connected to a shaft through the top surface of the horizontal plate. The motor is supported by the horizontal plate, and the motor can drive the shaft to rotate.

[0012] Preferably, the bottom end of the shaft extends into the interior of the preheating tube and is flush with the bottom surface of the preheating tube. The spiral blade is fixedly mounted on the outer surface of the bottom end of the shaft. When the shaft rotates, it can drive the spiral blade to rotate together, thereby conveying the rubber granule raw material inside the preheating tube into the feeding box.

[0013] Preferably, the inner wall of the preheating tube is provided with mounting grooves arranged in a ring array, and the electric heating tube is arranged in a one-to-one correspondence with the mounting groove and fixedly fitted inside the mounting groove, wherein the rubber particle raw material inside the preheating tube is heat pretreated by the electric heating tube.

[0014] Preferably, a clamp valve is installed on the connecting pipe. The clamp valve is a valve that opens and closes by clamping or releasing the medium in the pipe with two separable valve bodies. The clamp valve can control whether the rubber granule raw material can be discharged into the crushing box through the connecting pipe.

[0015] This utility model provides a manufacturing equipment for rubber processing. It has the following beneficial effects:

[0016] This rubber processing equipment allows rubber raw material particles added to the feeding hopper to enter the flow pipe and preheating pipe. The particles inside the preheating pipe are preheated by an electric heating element. A motor drives the spiral blades to rotate, conveying the rubber raw material particles from the preheating pipe into the feeding hopper. Subsequently, the rubber raw material particles from the flow pipe enter the preheating pipe through the feed hopper. This circulation of the rubber raw material particles within the preheating pipe, flow pipe, and feed hopper increases their flowability and ensures uniform heating, thereby improving subsequent pulverization. This solves the problem in existing devices where the heating plate is located on one side of the preheating feeding pipe, resulting in poor flowability of the rubber raw material particles, uneven heating, and difficulty in ensuring pulverization.

[0023] Example 1:

[0027] The preheating feeding assembly 5 includes a feeding box 51, a preheating pipe 52, and a flow pipe 53. The preheating pipe 52 is fixedly installed in the middle of the top surface of the connecting pipe 3. Flow pipes 53 are provided on both the left and right sides of the preheating pipe 52. A feeding hopper 54 is fixedly installed at the bottom end of the flow pipe 53. The bottom end of the feeding hopper 54 is arc-shaped and fixedly installed on the side wall at the bottom end of the preheating pipe 52. The top ends of the preheating pipe 52 and the flow pipe 53 are fixedly installed on the bottom surface of the feeding box 51. An electric heating pipe 56 and a spiral blade 510 are provided inside the preheating pipe 52.

[0028] The rubber raw material particles added inside the feeding box 51 will enter the flow pipe 53 and the preheating pipe 52. The particles inside the preheating pipe 52 are preheated by the electric heating pipe 56. The spiral blade 510 driven by the motor 58 can be rotated to transport the rubber raw material particles inside the preheating pipe 52 into the feeding box 51. Then, the rubber raw material particles inside the flow pipe 53 will enter the preheating pipe 52 through the feed hopper 54. This allows the rubber raw material particles to circulate in the preheating pipe 52, the flow pipe 53 and the feed hopper 54, which helps to increase the fluidity of the rubber raw material particles and achieve the purpose of uniform heating of the rubber raw material particles, thereby improving the subsequent crushing effect.

[0029] Furthermore, a horizontal plate 57 is fixedly installed in the middle of the top surface of the feeding box 51, and a motor 58 is fixedly installed in the middle of the top surface of the horizontal plate 57. The output end of the motor 58 passes through the top surface of the horizontal plate 57 and is fixedly connected to a shaft 59.

[0030] The motor 58 is supported by the horizontal plate 57, and the motor 58 can drive the shaft 59 to rotate.

[0031] Furthermore, the bottom end of the shaft 59 extends into the interior of the preheating tube 52 and is flush with the bottom surface of the preheating tube 52, and the spiral blade 510 is fixedly fitted onto the outer surface of the bottom end of the shaft 59.

[0032] When the shaft 59 rotates, it can drive the spiral blade 510 to rotate together, thereby conveying the rubber granule raw material inside the preheating pipe 52 into the feeding box 51.

[0033] Furthermore, the inner wall of the preheating tube 52 is provided with mounting grooves 55 arranged in a ring array, and the electric heating tube 56 is provided in a one-to-one correspondence with the mounting grooves 55 and is fixedly fitted inside the mounting grooves 55.

[0034] Among them, the rubber granule raw material inside the preheating tube 52 is heat-pretreated by the electric heating tube 56.

[0035] Furthermore, a clamp valve 4 is installed on the connecting pipe 3;

[0036] Among them, the clamp valve is a valve that opens and closes by clamping or releasing the medium in the pipeline with two separable valve bodies. The clamp valve 4 can control whether the rubber granule raw material can be discharged into the crushing box 1 through the connecting pipe 3.

[0037] The working principle and usage process of this utility model: When using this rubber processing manufacturing equipment, rubber granules are added to the inside of the feeding box 51. The rubber granules then enter the inside of the flow pipe 53 and the preheating pipe 52. Then, the electric heating tube 56 is energized to preheat the rubber granules inside the preheating pipe 52. During this process, the motor 58 is started to drive the shaft 59 and the spiral blade 510 to rotate. Through the rotation of the spiral blade 510, the rubber granules inside the preheating pipe 52 can be conveyed to the feeding box 51. Then, the rubber granules inside the flow pipe 53 will enter the inside of the preheating pipe 52 through the feeding hopper 54. This allows the rubber granules to circulate in the preheating pipe 52, the flow pipe 53, and the feeding hopper 54, so that the rubber granules are heated evenly. After preheating, the clamp valve 4 is opened, and then the rubber granules enter the inside of the connecting pipe 3 through the preheating pipe 52. Finally, they enter the inside of the crushing box 1 and are crushed by the crushing structure inside the crushing box 1 before being discharged.
