Description

Technical Field

[0001] This utility model belongs to the field of open mill accessories, specifically a heat insulation cover for open mill rollers made of plastic materials. Background Technology

[0002] An open mixing mill, also known as a rubber mixing mill, is an indispensable piece of equipment in rubber and plastics processing. Its main working components are two counter-rotating hollow rollers, one fixed and the other manually or electrically movable back and forth to adjust the roller gap and meet different operational needs. Raw rubber or rubber compounds are drawn into the gap between the two rollers under the rotation of the rollers and subjected to strong shearing action, thereby achieving the purpose of plasticizing or mixing.

[0003] Most plastic materials are granular after they are made into finished products. In order to meet the performance testing requirements of the materials, they are pressed into sheets to meet the requirements of the test methods. Since the plastic materials are granular, there is a possibility of air holes between the particles during the pressing process. In order to eliminate air holes and make the material properties more stable, the materials are first mixed in an open mill. To ensure the timeliness of the material test data, the rollers of the open mill are open and the temperature rises slowly, so it is usually in standby mode. This presents some problems.

[0004] On the one hand, the open mill emits heat when it is in the heat preservation state, which leads to frequent heating and slow overall temperature rise, affecting processing efficiency. On the other hand, the rollers are open, and there is a risk of burns when in standby mode.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a heat insulation cover for open mill rollers of plastic materials. Utility Model Content

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a heat insulation cover for the rollers of an open mill for plastic materials, including a base 1 and a heat insulation cover 5. The top of the base 1 is provided with an installation groove 17. The bottom of the installation groove 17 and both sides of the long side of the base 1 are provided with heat insulation plates 2. Both ends of the two side walls of the installation groove 17 are provided with connecting grooves 3. Each of the four sets of connecting grooves 3 is provided with an installation block 4. The heat insulation cover 5 is connected between the four sets of installation blocks 4. Both sides of the inner wall of the heat insulation cover 5 are provided with connecting parts for engaging and assembling with the installation blocks 4.

[0028] The rollers are covered by heat insulation covers 5 times, which keeps the rollers warm during the standby process, prevents the residual heat on the rollers from being lost quickly, and also plays a role in safety, saving electricity and improving efficiency, making it highly practical.

[0029] refer to Figure 2 A handle 6 is provided at the top of the base 1 above the insulation board 2, which is used to apply a moving force to the base 1.

[0030] refer to Figure 3 The base 1 has sliding rails 7 at both ends of the mounting groove 17 on the inner side. The top of each set of sliding rails 7 has a mounting groove 18. The two ends of the heat insulation cover 5 are corrugated telescopic structures, and the bottom of each end is connected to a slider 19 that slides through the mounting groove 18 and slides along the sliding rail 7.

[0031] In this design, by connecting the telescopic structures at both ends of the heat insulation cover 5 to the sliding rail 7 via the slider 19, the heat insulation cover 5 can be configured as a telescopic structure. During use, the two ends of the heat insulation cover 5 can be telescopically operated according to the operational needs of the staff.

[0032] refer to Figure 3 and Figure 4 The connecting components include a horizontal shaft 8, a T-shaped plate 9, a retaining spring 10, and a insert shaft 11. Both ends of the inner wall of the heat insulation cover 5 are provided with horizontal shafts 8. The end of the horizontal shaft 8 facing away from the heat insulation cover 5 is connected to an anti-detachment plate 12. A T-shaped plate 9 is slidably arranged between the two horizontal shafts 8 on the same side. Both ends of the horizontal section of the T-shaped plate 9 are connected to insert shafts 11. A retaining spring 10 sleeved on the outside of the horizontal shaft 8 is connected between the T-shaped plate 9 and the anti-detachment plate 12.

[0033] refer to Figure 3 The vertical section of the mounting block 4 has a slot 13 at its end, and the corresponding insertion shaft 11 is inserted into the slot 13.

[0034] The elastic force of the retaining spring 10 causes the T-shaped plate 9 to adhere tightly to the inner wall of the heat insulation cover 5, so that the T-shaped plate 9 drives the insertion shaft 11 to be inserted into the slot 13 opened on the mounting block 4, thereby positioning the heat insulation cover 5 between the four mounting blocks 4 through the insertion shaft 11.

[0035] refer to Figure 2 Both sides of the heat insulation cover 5 are provided with threaded sleeves 14, and the threaded sleeves 14 are internally threaded with push rods 15. One end of the push rod 15 passes through the heat insulation cover 5 and abuts against the vertical section of the T-shaped plate 9. The other end of the push rod 15 is connected to a knob 16.

[0036] By rotating the knob 16, the top rod 15 is rotated inward relative to the insulation cover 5. Then, the top rod 15 pushes the T-shaped plate 9, causing the T-shaped plate 9 to move on the two horizontal axes 8. During the movement, the insertion shaft 11 is disengaged from the mounting block 4, thereby terminating the connection between the insulation cover 5 and the mounting block 4.

[0037] Working principle: This utility model involves mounting the insulation cover 5 between four sliding tracks 7 via a slider 19. Before mounting, the knob 16 is rotated to rotate the top rod 15 inward relative to the insulation cover 5. The top rod 15 then pushes the T-shaped plate 9, causing it to move on the two horizontal axes 8 and press against the retaining spring 10. As the T-shaped plate 9 moves, it drives the insertion shaft 11 to move inward towards the insulation cover 5. The insulation cover 5 is then mounted between the four sliding tracks 7 via the slider 19, aligning the insertion shaft 11 with the slot 13 on the mounting block 4. The top rod 15 is then loosened, causing one end of the top rod 15 to move outward. During this movement, the T-shaped plate 9 loses its resistance and is pressed against the retaining spring 10. Under the action of elastic restoring force, it resets and moves. During the movement, it will drive the insertion shaft 11 to insert into the slot 13 into which the corresponding mounting block 4 is inserted, thus completing the assembly of the heat insulation cover 5. The heat insulation cover 5 is used to heat the roller. When the open mill is turned on for heating and in standby mode, the heat insulation cover 5 can reduce the heat loss of the roller, which is convenient for rapid heating during subsequent use and improves the overall efficiency. Moreover, the roller cover is set inside the heat insulation cover 5 to avoid it being exposed to the outside, reducing the risk of burns to the staff. When the heat insulation cover 5 needs to be replaced or maintained, the operation can be reversed. This makes it convenient to disassemble, clean or maintain and replace the heat insulation cover 5 during long-term use, improving the overall operability and maintainability.
