Description

Technical Field

[0001] The invention relates to the technical field of open mixing mills, in particular to an open mixing mill which is convenient for mixing materials. Background Art

[0002] The open mill is the abbreviation of open plastic refining machine. In plastic product factories, people are also used to calling it a two-roller mill. This is because the main working parts of the open mill are composed of two hollow rollers or drilled rollers that rotate inward in different directions. The roller on the side close to the operator is called the front roller. The front roller can be moved horizontally back and forth by manual or electric action to adjust the distance between the two rollers to meet the operating requirements; the rear roller is fixed and cannot be moved back and forth. The two rollers are generally the same size, but rotate relative to each other at different speeds. The speed difference between the two rollers produces a strong shearing effect on the material. The rubber material is drawn into the gap between the two rollers as the rollers rotate, and is subjected to strong shearing to achieve the purpose of plastication or mixing.

[0003] During the operation of the mixing mill, some materials (especially highly viscous materials such as rubber and plastic) will adhere to the surface of the roller, resulting in incomplete mixing of the materials. The traditional cleaning method is usually cumbersome and requires manual cleaning of the roller, which reduces work efficiency and safety. Therefore, an open mixing mill that is convenient for mixing is proposed. Summary of the invention

[0004] The present invention aims to solve the technical problem of how to scrape off the material adhering to the roller surface in time through a scraping device during the operation of the mixing mill to prevent affecting the material mixing effect and improve the working efficiency of the mixing mill, and provide a mixing mill that is convenient for mixing.

When the material is crushed by the roller, debris may splash outward, and the fallen scraper and mounting block can also prevent the debris from splashing outward.

[0058] 2. The present invention provides structures such as threaded rods, sliders, screening frames, racks, and the first gear. The materials are screened through the screen in the screening frame before being discharged, which can prevent larger materials from falling between the rollers and affecting the refining work, so that the materials are discharged evenly. In addition, the screen can also shake during the horizontal movement of the material discharge, which speeds up the efficiency of material discharge and prevents the screen from being blocked by the material.

[0059] 3. The present invention is provided with a blower, an air jet pipe, a switch, an L-shaped rod and other structures. When the scraper has not fallen, the L-shaped rod presses the switch and the blower does not work. After the scraper falls, the L-shaped rod is away from the switch and the blower works, which can blow hot air toward the piled materials to prevent the materials from cooling down and affecting the material mixing efficiency.

[0109] When the accumulated material needs to be heated, the second wedge block 20 drives the L-shaped rod 23 to move downward, the L-shaped rod 23 is away from the switch 22, the switch 22 is not pressed, the hair dryer 25 works, and the hair dryer 25 blows the external hot air to the jet pipe 24 through the connecting pipe 26, and then sprays the multiple nozzles 27 at the bottom of the jet pipe 24 to the material accumulated and folded on the surface of the refining roller 3, so as to prevent the material accumulated and folded on the surface of the refining roller 3 from cooling down.

[0110] When the first wedge block 19 moves away from the second wedge block 20, the spring 16 contracts and resets, driving the mounting block 17 to move upward, and the mounting block 17 drives the L-shaped rod 23 to move upward, driving the scraper 18 to move upward, and then the accumulated and folded materials rotate with the refining roller 3 and enter between the two refining rollers 3 for repeated calendering, thereby improving the material mixing effect.

[0111] The connecting pipe 26 is made of a hose.

[0112] The portion where the connecting pipe 26 communicates with the air injection pipe 24 is prevented from being damaged due to movement.

[0113] It includes a plurality of nozzles 27, which are evenly arranged at the lower part of the air injection pipe 24, the upper ends of the plurality of nozzles 27 are connected to the air injection pipe 24, and the lower ends are connected to the outside.

[0114] The hot air can be evenly sprayed toward the stacked and folded materials through the plurality of nozzles 27 .

[0115] Working principle: When using this equipment, the staff controls the heaters of the two refining rollers 3 through the controller 28 to heat the surface of the refining rollers 3, and then heats the material after it falls on the surface of the refining rollers 3, accelerates the softening of the material, improves the material mixing efficiency, and starts the motors of the two refining rollers 3. The two refining rollers 3 rotate in opposite directions, and then the staff pours the material into the screening frame 10. Then the staff starts the second forward and reverse motor 12 and the first forward and reverse motor 5 through the controller 28. The second forward and reverse motor 12 works, and the rotating shaft of the second forward and reverse motor 12 drives the first gear 14 to reciprocate, and the first gear 14 drives the rack 13 to swing in a direction parallel to the axis of the first forward and reverse motor 5, and the rack 13 drives the screening frame 10 to swing along the slide bar 9, and the screening frame 10 drives the screen 11 to swing, so that the material on the screen 11 falls evenly between the two refining rollers 3, and it can also prevent the screen 11 from being blocked.

[0116] The first forward and reverse motor 5 works, and the first forward and reverse motor 5 drives the threaded rod 6 to rotate forward. The rotation of the threaded rod 6 drives the slider 7 to move right. The slider 7 drives the first wedge block 19 to move right, drives the installation frame 8 to move right, the installation frame 8 drives the slide bar 9 to move right, and the slide bar 9 drives the screening frame 10 to move right, so that the material can be evenly distributed between the two refining rollers 3.

[0117] When the slider 7 drives the first wedge block 19 to move right, the first wedge block 19 intermittently drives the second wedge block 20 to descend, and the second wedge block 20 drives the L-shaped rod 23 to descend, driving the mounting block 17 to descend, and the mounting block 17 stretches the spring 16 to drive the scraper 18 to descend, and the scraper 18 descends to the surface of the refining roller 3. The refining roller 3 is in a rotating state, and the time for the scraper 18 to descend to the surface of the refining roller 3 is less than the time for the refining roller 3 to rotate one circle, and then the scraper 18 scrapes off the material adhering to the surface of the refining roller 3 to prevent it from affecting the mixing effect of the material, and the scraper 18 will also prevent the material from rotating with the refining roller 3, so that the material can be temporarily piled up and folded together, and the fallen scraper 18 and the mounting block 17 can also prevent the debris from splashing outward.

[0118] When the second wedge block 20 drives the L-shaped rod 23 to move downward, the L-shaped rod 23 is away from the switch 22, the switch 22 is not pressed, and the hair dryer 25 works. The hair dryer 25 blows the external hot air to the air injection pipe 24 through the connecting pipe 26, and then sprays the materials accumulated and folded on the surface of the open refining roller 3 from the multiple nozzles 27 at the bottom of the air injection pipe 24 to prevent the materials accumulated and folded on the surface of the open refining roller 3 from cooling down.

[0119] When the first wedge block 19 moves away from the second wedge block 20, the spring 16 contracts and resets, driving the mounting block 17 to move upward, and the mounting block 17 drives the L-shaped rod 23 to move upward, driving the scraper 18 to move upward, and then the accumulated and folded materials rotate with the refining roller 3 and enter between the two refining rollers 3 for repeated calendering, thereby improving the material mixing effect.

[0120] When the mounting block 17 drives the L-shaped rod 23 to move upward to the push switch 22, the hair dryer 25 stops working.

[0121] When the rotating shaft of the first forward and reverse motor 5 drives the threaded rod 6 to rotate in the opposite direction, the threaded rod 6 rotates in the opposite direction and drives the slider 7 to move left, the slider 7 drives the first wedge block 19 to move left, drives the mounting frame 8 to move left, the mounting frame 8 drives the slide bar 9 to move left, the slide bar 9 drives the screening frame 10 to move left, so that the material falls evenly between the two refining rollers 3, and the subsequent working process is the same as described above.

[0122] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
