Description

Technical Field

[0001] This utility model relates to the field of open mill technology, specifically an environmentally friendly open mill for rubber production and processing. Background Technology

[0002] Rubber is a highly elastic polymer material, mainly derived from natural sources or manufactured through chemical synthesis. Rubber is divided into two types: natural rubber and synthetic rubber. Both natural and synthetic rubber have the characteristic of being able to undergo large deformations when subjected to force and quickly return to their original shape after the external force is removed. Rubber is widely used in tires, seals, conveyor belts, hoses, wire and cable sheaths, and other fields. Due to its excellent mechanical properties, chemical corrosion resistance, and aging resistance, it has become one of the indispensable basic materials of modern industry.

[0003] Existing rubber production and processing requires the use of open mills. Open mills can improve the efficiency of rubber material mixing, plasticizing, and molding, while also reducing environmental impact. Open mill equipment typically incorporates design concepts such as energy saving, emission reduction, and noise reduction. During the operation of an open mill, rubber raw materials are added between two rollers inside the mill. The two rollers rotate in opposite directions to compress the rubber raw materials, plasticizing and mixing them. However, the rubber raw materials tend to accumulate between the two rollers and are difficult to squeeze into the gap between the rollers, causing feeding difficulties in the open mill and affecting the efficiency of rubber production and processing. Manual tools are needed to squeeze the rubber raw materials into the gap between the two rollers, which poses certain safety hazards. Utility Model Content

[0031] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] Example

[0033] like Figures 1-5 As shown, an environmentally friendly rubber production and processing open mill includes: an open mill body 1, rollers 101, an operating platform 102, an extrusion assembly, and a positioning assembly. The open mill body 1 has two rollers 101 inside, and an operating platform 102 is installed on one side of the outer end of the open mill body 1. The top of the open mill body 1 is provided with an extrusion assembly, which includes: a fixed frame 2, a lifting electric cylinder 201, a telescopic rod 202, an extrusion block 203, an installation block 204, and a through hole 205. The top of the open mill body 1 is provided with a positioning assembly, which includes: a positioning rod 3, a fixed block 301, and a sliding sleeve 302.

[0034] The two rollers 101 are each equipped with heating tubes that are wired to the operating platform 102. One end of each roller 101 is rotatably connected to one side of the inner wall of the open mill body 1 via bearings, and the other end is installed and connected to the output shaft of the rotary motor inside the open mill body 1.

[0035] When using the open mill body 1, first plug the power cord plug on the back of the open mill body 1 into the external socket to connect the power supply, so that the open mill body 1 can be powered on. Then, start the heating tubes inside the two rollers 101 through the operating table 102, and set the heating temperature on the operating table 102. The operating table 102 is equipped with an electronic screen for displaying the temperature value, which is convenient for the operator to operate and view. After the two rollers 101 are preheated, rubber raw material granules are put between the two rollers 101, and the two rotary motors are started through the operating table 102. One rotary motor rotates forward and the other rotates in reverse, which drives the two rollers 101 to rotate in opposite directions, extruding and heating the rubber raw material granules at the same time, so that the rubber raw material granules are plasticized and mixed together after being heated, thus completing the rubber production process.

[0036] The main body 1 of the open mill, the roller 101, the operating platform 102 and the rotary motor are all conventional designs existing in this field. Their working principles and structural designs are common knowledge to those skilled in the art and belong to existing technology. Therefore, they will not be described in detail.

[0037] The two rollers 101 are equipped with a tray 4 at the bottom, and a handle 401 is installed on the outer end of the tray 4. The two sides of the inside of the open mill body 1 are respectively equipped with support blocks 402, which are tightly attached to the two ends of the tray 4. During the use of the open mill body 1, the tray 4 is placed at the bottom of the two rollers 101, and the two ends of the tray 4 are supported by the support blocks 402. That is, the tray 4 is stably placed at the bottom of the two rollers 101. The rubber raw material falling between the two rollers 101 can be collected by the tray 4 to avoid soiling the rubber raw material.

[0038] When using the rubber raw material collected in tray 4, grasp the handle 401 and pull tray 4 outward to easily remove the rubber raw material in tray 4 and put it back between the two rollers 101 for continued extrusion and processing by the two rollers 101.

[0039] The main body 1 of the open mill is equipped with a support plate 5. The support plate 5 fits tightly with the bottom of the pallet 4. During the use of the pallet 4, the bottom of the pallet 4 can be supported by the support plate 5 on the basis of the support blocks 402 supporting the two ends of the pallet 4, which increases the stability of the pallet 4.

[0040] The main body 1 of the open mill is equipped with a fixed frame 2 on top, a lifting electric cylinder 201 is installed on top of the fixed frame 2, a telescopic rod 202 is installed at the bottom of the lifting electric cylinder 201, an extrusion block 203 is provided inside the fixed frame 2, and an installation block 204 is fixed between the extrusion block 203 and the telescopic rod 202 by bolts. A through hole 205 is opened on the top of the fixed frame 2, and the telescopic rod 202 is located inside the through hole 205.

[0041] When the rubber raw material is extruded and processed by two rollers 101, and the rubber raw material is difficult to feed due to accumulation between the two rollers 101, the top of the two rollers 101 is equipped with an extrusion block 203, and the extrusion block 203 is directly opposite the roller gap between the two rollers 101. At this time, the lifting electric cylinder 201 is started by operating the machine platform 102. The lifting electric cylinder 201 drives the telescopic rod 202 to move downward, so that the telescopic rod 202 pushes the extrusion block 203 downward to the two rollers 101, extruding the rubber raw material accumulated between the two rollers 101. This facilitates smooth feeding during the rotation of the two rollers 101, improves the work efficiency of rubber production and processing, solves the safety hazards of manual operation with tools, avoids waste of rubber raw materials, and achieves the purpose of economical and environmentally friendly production.

[0042] When the heating tube, rotary motor and lifting electric cylinder 201 are in use, the operating platform 102 is electrically connected to the heating tube, rotary motor and lifting electric cylinder 201 respectively, and the operating platform 102 is provided with start and stop buttons for controlling the heating tube, rotary motor and lifting electric cylinder 201 respectively. The control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art. This part is not the innovation of this utility model.

[0043] The extrusion block 203 is arranged in a trapezoidal structure and is made of stainless steel. When the extrusion block 203 is in use, it is arranged in a trapezoidal structure. During the process of extruding the rubber raw material between the two rollers 101, the bottom end of the extrusion block 203 fits into the two rollers 101 to prevent the rubber raw material from falling out from the sides of the two rollers 101.

[0044] The extrusion block 203 has positioning rods 3 on both sides of its top. The positioning rods 3 are fixed to the extrusion block 203 by bolts, and the fixing blocks 301 are fixed to the positioning blocks 203. The fixing frame 2 has sliding sleeves 302 on both sides of its top that are slidably connected to the positioning rods 3. When the telescopic rod 202 drives the extrusion block 203 to move up and down to squeeze the rubber material into the roller gap between the two rollers 101, the positioning rods 3 on both sides of the top of the extrusion block 203 and the sliding sleeves 302 on both sides of the top of the fixing frame 2 slide together to ensure that the extrusion block 203 has good stability during the up and down movement. It also makes the extrusion block 203 and the roller gap between the two rollers 101 on the same vertical line, which helps the rubber material to be squeezed into the roller gap between the two rollers 101.

[0045] Among them, limit blocks 303 are installed at the top of both positioning rods 3. The length and width of the limit blocks 303 are larger than the length and width of the sliding sleeve 302. During the up and down sliding of the positioning rods 3 at the sliding sleeve 302, the setting of the limit blocks 303 can prevent the positioning rods 3 from moving out of the sliding sleeve 302, ensuring that the positioning rods 3 can slide up and down normally.

[0046] Working principle:

[0047] When using the open mill body 1, first plug the power cord plug on the back of the open mill body 1 into the external socket to connect the power supply, so that the open mill body 1 can be powered on. Then, start the heating tubes inside the two rollers 101 through the operating table 102, and set the heating temperature on the operating table 102. The operating table 102 is equipped with an electronic screen for displaying the temperature value, which is convenient for the operator to operate and view. After the two rollers 101 are preheated, rubber raw material granules are put between the two rollers 101, and the two rotary motors are started through the operating table 102. One rotary motor rotates forward and the other rotates in reverse, which drives the two rollers 101 to rotate in opposite directions, extruding and heating the rubber raw material granules at the same time, so that the rubber raw material granules are plasticized and mixed together after being heated, thus completing the rubber production process.

[0048] When the rubber raw material is extruded and processed by two rollers 101, and the rubber raw material is difficult to feed due to accumulation between the two rollers 101, the top of the two rollers 101 is equipped with an extrusion block 203, and the extrusion block 203 is directly opposite the roller gap between the two rollers 101. At this time, the lifting electric cylinder 201 is started by operating the machine platform 102. The lifting electric cylinder 201 drives the telescopic rod 202 to move downward, so that the telescopic rod 202 pushes the extrusion block 203 downward to the two rollers 101, extruding the rubber raw material accumulated between the two rollers 101. This facilitates smooth feeding during the rotation of the two rollers 101, improves the work efficiency of rubber production and processing, solves the safety hazards of manual operation with tools, avoids waste of rubber raw materials, and achieves the purpose of economical and environmentally friendly production.

[0049] When the telescopic rod 202 drives the extrusion block 203 to move up and down to squeeze the rubber material into the gap between the two rollers 101, the positioning rods 3 on both sides of the top of the extrusion block 203 and the sliding sleeves 302 on both sides of the top of the fixing frame 2 slide together to ensure that the extrusion block 203 has good stability during the up and down movement. It also makes the extrusion block 203 and the gap between the two rollers 101 on the same vertical line, which helps the rubber material to be squeezed into the gap between the two rollers 101.
