Description

Technical Field

[0002] Floor covering linoleum is a manufacturing process that mainly includes steps such as ingredient mixing, internal mixing, calendering, cutting, molding, and hydraulic pressing. Among these steps, calendering is a crucial one, the main purpose of which is to mix the ingredients evenly and adjust parameters such as the hardness and viscosity of the raw material to prepare it for subsequent calendering and cutting steps.

[0003] Existing open mills for flooring require manual operation for both feeding and unloading, increasing labor costs, increasing workload, and reducing product efficiency. A patent with publication number CN108858866A discloses an automatic material turning and conveying production line for flooring open mills and its production process, including an open mill unit, a turning conveyor belt, a feeding conveyor belt, and a drive device. The open mill unit consists of three open mills arranged consecutively. Each open mill has a turning conveyor belt at its discharge end and a feeding conveyor belt at the feed end of the next open mill.

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1 - Figure 9 As shown, a material turning and conveying device for the open mixing production of flooring includes a base 1. Mounting plates 3 are symmetrically arranged on the left and right sides of the upper surface of the base 1, and four sets of mounting plates 3 are vertically arrayed. Base 2 is located at the lower end of the upper three sets of mounting plates 3. A lower through groove is opened inside the left side of each of the three base 2 sets. Open mixing mill drive devices 4 are located at the right end of the upper surface of the three base 2 sets and the base 1. Open mixing rollers 1 and 2 are connected to the left side of each of the four sets of open mixing mill drive devices 4, so that the device has a total of four rubber mixing mills arranged from top to bottom. By stacking the four rubber mixing mills, no additional conveying device is needed, reducing the loading and unloading costs. The space occupied by the set is as follows: the bottom of the open mill is equipped with a conveying device, which can transport the rubber sheet after mixing to the next step. The circumferential surfaces of the left and right ends of the open mill roller 5 are equipped with rotating gears 13. The rotating gears 13 are connected to the turning traction roller 7 through the driven gear 12. The left and right ends of the turning traction roller 7 are respectively equipped with counterweight bearing seats 10 and climbing gears 11 from the outside to the inside. The counterweight bearing seats 10 and climbing gears 11 are movably installed inside the mounting plate 3. The end of the open mill roller 6 is connected to the guide roller 8 through the synchronous belt mechanism 32. The left and right ends of the guide roller 8 are rotatably installed inside the mounting plate 3.

[0037] It should be noted that when the material turning traction roller 7 is located at Figure 4 When the material is in the middle position, the distance between the material turning traction roller 7 and the open milling roller 5 is slightly smaller than the thickness of the rubber compound produced by open milling. This allows the material turning traction roller 7 to cooperate with the open milling roller 5 to clamp the rubber compound when it moves planetarily on the surface of the open milling roller 5. This enables the material turning traction roller 7 to smoothly pull the rubber compound above the open milling roller 5, so that the rubber compound covers the circumferential surface of the open milling roller 5. This allows the rubber compound to be automatically mixed on the roller without the need for manual support for feeding, saving the labor intensity of workers in rubber mixing and improving the efficiency of rubber mixing.

[0038] The surface of the mounting plate 3 is provided with an arc-shaped rising groove 301 and an arc-shaped falling groove 303. The upper ends of the arc-shaped rising groove 301 and the arc-shaped falling groove 303 are connected by a vertical connecting groove 302, so that when the material turning traction roller 7 is located inside the upper end of the arc-shaped rising groove 301, it can move into the upper end of the arc-shaped falling groove 303 through the vertical connecting groove 302. The lower ends of the arc-shaped rising groove 301 and the arc-shaped falling groove 303 are connected by an arc-shaped connecting groove 304, so that when the material turning traction roller 7 is located inside the lower end of the arc-shaped falling groove 303, it can move to the lower end of the arc-shaped rising groove 301 through the arc-shaped connecting groove 304. The end of the material turning traction roller 7, the counterweight bearing seat 10, and the climbing gear 11 are all movably installed inside the lower end of the arc-shaped rising groove 301. The interior of the arc-shaped rising groove 301 is provided with an arc-shaped toothed plate 306, and the teeth of the arc-shaped toothed plate 306 match the teeth of the climbing gear 11. Through the meshing of the climbing gear 11 and the arc-shaped toothed plate 306, the turning traction roller 7 can generate traction force and then perform planetary motion on the surface of the open mill roller 5. The interior of the arc-shaped connecting groove 304 is provided with an arc-shaped push plate 14, and the upper surface of the arc-shaped push plate 14 abuts against the counterweight bearing seat 10. The setting of the counterweight bearing seat 10 provides weight to the turning traction roller 7, so that when the turning traction roller 7 is located inside the arc-shaped falling groove 303, because the turning traction roller 7 is no longer subject to the limiting effect, the gravity of the turning traction roller 7 is released, allowing the turning traction roller 7 to move downward inside the arc-shaped falling groove 303.

[0039] It should be noted that when the rubber compound needs to be pulled, the turning traction roller 7 is pushed into the lower end of the arc-shaped rising groove 301 through the arc-shaped connecting groove 304. When the turning traction roller 7 is located inside the lower end of the arc-shaped rising groove 301, the rotating gear 13 rotates, which drives the driven gear 12 and the turning traction roller 7 to rotate, causing the climbing gear 11 on the turning traction roller 7 to move inside the arc-shaped rising groove 301. This causes the turning traction roller 7 to rotate planetarily around the open milling roller 5, so that the rubber compound between the turning traction roller 7 and the open milling roller 5 can be wrapped around the circumferential surface of the open milling roller 5. Then, when the turning traction roller 7 moves to the upper end of the arc-shaped rising groove 301... During the initial rotation, the rubber compound wrapped around the first milling roller 5 will first rotate for a while, so that the rubber compound between the first milling roller 5 and the second milling roller 6 will be connected together. Then, the turning traction roller 7 will move through the vertical connecting groove 302 to the upper end of the arc-shaped drop groove 303. Then, under the gravity of the counterweight bearing seat 10, it will move downward inside the arc-shaped drop groove 303, so that the turning traction roller 7 falls into the lower end of the arc-shaped drop groove 303. When the turning traction roller 7 is located inside the lower end of the arc-shaped drop groove 303, it cooperates with the guide roller 8 to vertically convey the cut rubber compound downward, so that the rubber compound falls into the open mill below for multiple turning operations.

[0040] An annular moving plate 15 is provided on the side of the arc-shaped push plate 14 away from the turning traction roller 7. The annular moving plate 15 is connected to the rotating shaft 17 through the limiting connecting plate 16. A motor 18 is provided on the outer wall of the mounting plate 3. The power output end of the motor 18 is connected to the rotating shaft 17 through a coupling. A receiving groove 305 is provided inside the mounting plate 3. The receiving groove 305 is connected to the arc-shaped rising groove 301 and the arc-shaped falling groove 303. The arc-shaped push plate 14 matches the receiving groove 305, so that the arc-shaped push plate 14 can be moved into the receiving groove 305 as a whole. An electric cylinder 21 is provided on the upper surface of the outer side of the mounting plate 3. A lifting plate 22 is provided at the upper end of the electric cylinder 21. A wedge-shaped lifting push block 2 is provided on the inner side of the lifting plate 22. 3. The wedge-shaped lifting push block 23 is set at the bottom of the vertical connecting groove 302. The upper end of the vertical connecting groove 302 is provided with a wedge-shaped protrusion 31. With the cooperation of the wedge-shaped lifting push block 23 and the wedge-shaped protrusion 31, after the wedge-shaped lifting push block 23 pushes the turning traction roller 7 to the upper end of the arc-shaped falling groove 303, the turning traction roller 7 has a large tilt angle, so that the turning traction roller 7 can fall more smoothly from the inside of the arc-shaped falling groove 303 by weight. The side wall of the lifting plate 22 is provided with a vertical rod 24. The lower end of the vertical rod 24 is provided with an inverted U-shaped connecting plate 25. The inner sides of the front and rear ends of the inverted U-shaped connecting plate 25 are provided with arc-shaped protrusions 26. The protruding end of the arc-shaped protrusion 26 abuts against the outer surface of the limiting connecting plate 16.

[0041] It should be noted that when the arc-shaped push plate 14 is located inside the arc-shaped drop trough 303, and the counterweight bearing seat 10 at the end of the turning traction roller 7 is located to the left of the arc-shaped push plate 14, the rotation of the arc-shaped push plate 14 can move the turning traction roller 7 through the arc-shaped connecting groove 304 into the lower end of the arc-shaped rising trough 301. Then, before the turning traction roller 7 moves into the lower right side of the arc-shaped rising trough 301, the arc-shaped push plate 14 cannot be reset, because at this time the upper end of the arc-shaped push plate 14 is used as the inner bottom of the lower end of the arc-shaped rising trough 301. The sealed splicing allows the counterweight bearing seat 10 to move smoothly from the lower end of the arc-shaped rising groove 301 to the upper end of the arc-shaped rising groove 301. When the turning traction roller 7 performs planetary motion on the open mill roller 5, the motor 18 drives the rotating shaft 17 to rotate, so that the rotating shaft 17 drives the arc-shaped push plate 14 to rotate through the limiting connecting plate 16 and the annular moving plate 15, so that the arc-shaped push plate 14 moves to be flush with the receiving groove 305. Then, the electric cylinder 21 drives the lifting plate 22, the wedge-shaped lifting push block 23 and the vertical rod 2 4. Moving upwards, the wedge-shaped lifting pusher 23 pushes the material-turning traction roller 7 upwards to the upper end of the arc-shaped drop trough 303. The vertical rod 24 drives the inverted U-shaped connecting plate 25 and the arc-shaped protrusion 26 upwards to above the limiting connecting plate 16, so that the elastic force of the elastic telescopic rod 20 is released, pushing the arc-shaped pusher plate 14 into the receiving groove 305. This ensures that when the material-turning traction roller 7 falls from the upper end of the arc-shaped drop trough 303 to the lower end of the arc-shaped drop trough 303 by gravity, the arc-shaped pusher plate 14 will not obstruct the material-turning traction. After the material turning traction roller 7 moves to the left side of the arc-shaped push plate 14 due to inertia, the electric cylinder 21 works again, driving the arc-shaped protrusion 26 to move downward, pushing the arc-shaped push plate 14 out of the receiving groove 305 and into the lower end of the arc-shaped falling groove 303, so that when the material turning traction roller 7 falls back, it will only land on the left end of the arc-shaped push plate 14. At this time, the material turning traction roller 7 and the guide roller 8 cooperate to form a vertically downward guiding space, so that the material after rubber mixing is moved downward through the material turning traction roller 7 and the guide roller 8.

[0042] Preferably, the rotating shaft 17 is rotatably mounted on the mounting plate 3. The surface of the rotating shaft 17 is provided with a groove 33. The limiting connecting plate 16 is slidably mounted inside the rotating shaft 17 via a slider 34. An elastic telescopic rod 20 is movably mounted inside the mounting plate 3. An annular abutment plate 19 is provided at the outer end of the elastic telescopic rod 20. The outer side of the annular abutment plate 19 abuts against the inner side of the limiting connecting plate 16. The groove 33 and the slider 34 are provided so that the limiting connecting plate 16 can move horizontally on the rotating shaft 17 without affecting the rotation of the rotating shaft 17, thereby driving the limiting connecting plate 16 to rotate.

[0043] A scraping mechanism 9 is provided on the rear side of the open mill roller 5. The scraping mechanism 9 includes an electric cylinder 901, which is mounted on the upper surface of the mounting plate 3. A movable connecting plate 902 is provided at the rear end of the electric cylinder 901. A scraper 903 is provided on the front of the lower end of the movable connecting plate 902, and the scraper 903 is located directly behind the middle of the open mill roller 5. After the open mill has been mixing rubber for a certain period of time, the electric cylinder 901 is activated, which drives the scraper 903 to move horizontally forward through the movable connecting plate 902. This causes the tip of the scraper 903 to move to the middle of the rear end of the open mill roller 5, which can cut the rubber material wrapped around the circumference of the open mill roller 5. At the same time, as the open mill roller 5 continues to rotate, the rubber material adhering to the surface of the open mill roller 5 can be removed. When the scraper 903 scrapes the rubber material, the turning traction roller 7 is located inside the lower end of the arc-shaped drop trough 303. The turning traction roller 7 and the guide roller 8 form a guiding space. The cut rubber material will fall between the turning traction roller 7 and the guide roller 8. The guide roller 8 rotates inward under the action of the synchronous belt mechanism 32, which drives the rubber material to move vertically downward. At the same time, it drives the turning traction roller 7 to rotate inward, so that a section of the rubber material initially produced by the scraper 903 will fall on the upper surface and rear side of the turning traction roller 7. Under the rotation traction of the turning traction roller 7, it will be pulled to the middle of the turning traction roller 7 and the guide roller 8, so that the rubber material can smoothly fall through the lower through groove opened inside the base 2 into the two open mixing rollers below for the next step of rubber mixing.

[0044] Preferably, the upper end of the mounting plate 3 is provided with a movable groove 29 and a side passage groove 30, and the movable groove 29 is connected to the side passage groove 30. The movable groove 29 is also connected to the vertical connecting groove 302. The upper surface of the lifting plate 22 is provided with a baffle 27 and a sealing plate 28. The baffle 27 matches the movable groove 29 and is located directly below the movable groove 29, so that when the baffle 27 moves vertically, it can move into the interior of the movable groove 29 without affecting the vertical movement of the baffle 27. The baffle 27 can abut and limit the end of the turning traction roller 7, preventing the turning traction roller 7 from shifting horizontally and affecting the use effect of the turning traction roller 7. The sealing plate 28 abuts against the outer wall of the mounting plate 3, and the upper end of the sealing plate 28 is located above the side passage groove 30, further limiting the lifting plate 22 and improving the vertical movement effect of the lifting plate 22. The lifting plate 22 is located inside the side passage groove 30, providing space for the vertical movement of the lifting plate 22.

[0045] When the present invention is in use, before rubber mixing, the turning traction roller 7 is located inside the lower end of the arc-shaped drop trough 303, and at this time the pushing end of the arc-shaped push plate 14 abuts against the counterweight bearing seat 10 at the end of the turning traction roller 7. Then, the rubber material to be processed is transported to the uppermost open mill roller 5 and open mill roller 6 through the conveying device. The open mill drive equipment 4 drives the open mill roller 5 and open mill roller 6 to rotate to carry out rubber mixing.

[0046] After the rubber compound is extruded downwards a short distance, the motor 18 starts, driving the limiting connecting plate 16, the annular moving plate 15, and the arc-shaped push plate 14 to rotate via the rotating shaft 17. This causes the arc-shaped push plate 14 to push the turning traction roller 7 upwards, moving it through the arc-shaped connecting groove 304 into the lower end of the arc-shaped rising groove 301. At this time, the driven gear 12 at the end of the turning traction roller 7 meshes with the rotating gear 13 at the end of the open mill roller 5. As the rotating gear 13 rotates, it drives the turning traction roller 7 to rotate via the driven gear 12. The rubber compound falling on the surface of the turning traction roller 7 is squeezed onto the turning traction roller during the rotation. Between the 7 and the open milling roller 5, the material turning traction roller 7 rotates simultaneously. The climbing gear 11 at its end meshes with the arc-shaped toothed plate 306 inside the arc-shaped rising groove 301 to generate a climbing force, so that the material turning traction roller 7 can make planetary motion with the open milling roller 5 as the target. During the movement of the material turning traction roller 7, it will pull the rubber material to wrap around the surface of the open milling roller 5. After the material turning traction roller 7 moves to the upper end of the arc-shaped rising groove 301, the wedge-shaped lifting push block 23 temporarily does not push the material turning traction roller 7 upward, so that the material turning traction roller 7 continues to pull the rubber material. After the rubber material comes into contact with the initial material, the traction work is completed.

[0047] As the material-turning traction roller 7 moves upward, the motor 18 starts, driving the arc-shaped push plate 14 back to its initial position. Then, the electric cylinder 21 starts, driving the lifting plate 22, the wedge-shaped lifting push block 23, and the vertical rod 24 to move upward. The wedge-shaped lifting push block 23 pushes the material-turning traction roller 7 upward to the upper end of the arc-shaped drop trough 303. The vertical rod 24 drives the inverted U-shaped connecting plate 25 and the arc-shaped protrusion 26 to move upward above the limiting connecting plate 16, causing the elastic force of the elastic telescopic rod 20 to be released, pushing the arc-shaped push plate 14 into the receiving groove 305, so that the material-turning traction roller 7 can move from the arc-shaped drop trough 305. When the upper end of 03 falls into the lower end of the arc-shaped drop trough 303 by gravity, the arc-shaped push plate 14 will not block the turning traction roller 7. After the turning traction roller 7 moves to the left side of the arc-shaped push plate 14 due to inertia, the electric cylinder 21 works again, driving the arc-shaped protrusion 26 to move downward, pushing the arc-shaped push plate 14 out of the receiving groove 305 and into the lower end of the arc-shaped drop trough 303, so that when the turning traction roller 7 falls back, it will only land on the left end of the arc-shaped push plate 14. At this time, the turning traction roller 7 and the guide roller 8 cooperate to form a vertically downward guide space, waiting to convey the rubber material after preliminary mixing downward.

[0048] After the set mixing time is reached, start the electric cylinder 901. The moving connecting plate 902 drives the scraper 903 to move horizontally forward, so that the tip of the scraper 903 moves to the middle of the rear end of the open mixing roller 5, cutting off the rubber material wrapped around the circumference of the open mixing roller 5. The rubber material falls between the guide roller 8 and the turning traction roller 7. At this time, the open mixing roller continues to rotate, and the synchronous belt mechanism 32 drives the guide roller 8 to rotate. The guide roller 8 moves the rubber material vertically downward to the space between the open mixing roller 5 and the open mixing roller 6 below. Repeat the above steps three times, and perform four mixing operations on the rubber material.
