[0002] An open mixing mill is the abbreviation of an open rubber mixing mill. It is a rubber mixing machine with exposed rollers used to prepare plasticized rubber, mixed rubber, or for hot mixing and molding. Rubber tapping is required during the mixing process or at the end of the mixing process to facilitate rubber collection. When processing sealing strips, an open mixing mill is required for rubber mixing.

The rubber tapping device for the mixing mill is provided with a first driving mechanism and a cutting mechanism, so that the telescopic end of the telescopic rod is extended, thereby driving the sliding plate to move, so that the T-shaped block pushes the cross bar to move, thereby driving the first rotating plate and the second rotating plate to rotate, so as to realize the cutting of the rubber material, and avoid the problem of low manual cutting precision. By providing a second driving mechanism, the output shaft of the driving motor is rotated, the threaded rod is driven to rotate, and the movable plate threadedly connected thereto is moved, thereby driving the fixed tube to move, so that the blade can cut the rubber material on the rollers of different lengths, avoid the replacement of the cutter head, and improve the work efficiency. However, the rubber tapping device can only cut the rubber horizontally. When tapping the rubber, large pieces of rubber need to be separated vertically in order to collect the rubber. The rubber tapping device can only perform one-way single-time tapping, which is inconvenient during use.

[0004] To this end, we propose a rubber tapping device for a mixing mill that can perform multi-directional and multiple rubber tapping for processing sealing strips. Utility Model Content

DETAILED DESCRIPTION

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] Embodiment 1: A rubber tapping device for processing sealing strips, such as Figure 1-Figure 7As shown, it includes a mounting frame 1, a first motor 2, a first rotating rod 3, a rubber mixing roller 4, a gear 5, a conveying assembly, a hand wheel 9, a second rotating rod 10, a first blade 11, a first spring 12 and a second blade 13. The right part of the mounting frame 1 is fixedly connected to the first motor 2, and the left part of the mounting frame 1 is rotatably connected to the front and rear symmetrical first rotating rod 3, the front first rotating rod 3 is connected to the output shaft of the first motor 2, the first rotating rod 3 is fixedly connected to the rubber mixing roller 4, and the left parts of the front and rear rubber mixing rollers 4 are fixedly connected with mutually meshing gears 5. The mounting frame 1 is provided with a conveying assembly for conveying rubber blocks, the upper position of the front part of the mounting frame 1 is rotatably connected to the second rotating rod 10, the left part of the second rotating rod 10 is fixedly connected to the hand wheel 9, the second rotating rod 10 is slidably connected to the first blades 11 distributed equidistantly, there is friction between the first blade 11 and the second rotating rod 10, the left front part of the mounting frame 1 is slidably connected to the second blade 13, and the first spring 12 is connected between the second blade 13 and the mounting frame 1.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the conveying assembly includes a second motor 6, a conveying roller 7 and a conveyor belt 8. The second motor 6 is fixedly connected to the lower rear position of the left side of the mounting frame 1, and the lower left part of the mounting frame 1 is rotatably connected to the front and rear symmetrical conveying rollers 7. The rear conveying rollers 7 are connected to the output shaft of the second motor 6, and the conveyor belt 8 is sleeved between the front and rear conveying rollers 7.

[0026] like Figure 1 As shown, a guide plate 20 is also included, and the guide plate 20 is fixedly connected to the lower left portion of the front side of the mounting frame 1.

[0027] like Figure 1 As shown, a blocking plate 21 is also included, and the blocking plate 21 is fixedly connected to the upper rear portion of the mounting frame 1 .

[0028] When using the device, the staff starts the first motor 2, and the output shaft of the first motor 2 rotates to drive the first rotating rod 3 at the front to rotate. Under the action of the gear 5, the first rotating rod 3 at the rear rotates together, and the rotation of the first rotating rod 3 drives the rubber mixing roller 4 to rotate. The rubber mixing roller 4 can be rotated to mix rubber. When mixing rubber, the blocking plate 21 can block the rubber block to prevent the rubber block from falling backward. After the rubber block is mixed, the staff drives the second rotating rod 10 to rotate through the hand wheel 9, and the rotation of the second rotating rod 10 drives the first blade 11 to rotate downward and rest on the conveyor belt 8. When the mixed rubber block falls from the lower side of the rubber mixing roller 4 and moves onto the conveyor belt 8, the conveyor roller 7 is driven to rotate by the second motor 6, thereby controlling the rotation of the conveyor belt 8. The conveyor belt 8 The mixed rubber block is conveyed forward by rotation. When the rubber block moves forward, the first blade 11 cuts the rubber block vertically. At the same time, the staff can control the first blade 11 to slide on the second rotating rod 10 to adjust the distance, thereby adjusting the size of the divided rubber block. The divided rubber block continues to move forward with the conveyor belt 8. At this time, the staff can control the second blade 13 to slide downward to cut the rubber block horizontally. Under the action of the first spring 12, the second blade 13 will automatically reset upward after cutting, and the rubber block sent forward by the conveyor belt 8 will move to the guide plate 20 for guidance, so that the staff can collect the rubber. When the use of this device is completed, the staff turns off the first motor 2. In this way, multi-directional and multiple rubber tapping can be carried out to improve the efficiency of rubber tapping.

[0029] Embodiment 2: Based on embodiment 1, Figure 5 As shown, it also includes a fixing component for fixing the position of the first blade 11, the fixing component includes an insert rod 14, a mounting block 15 and a second spring 16, the mounting block 15 is fixedly connected to the upper side of the hand wheel 9, the insert rod 14 is slidably connected to the mounting block 15, the insert rod 14 is inserted into the mounting frame 1, and the second spring 16 is connected between the insert rod 14 and the mounting block 15.

[0030] By setting a fixing component, the position of the first blade 11 can be fixed. The specific operation is as follows: in the initial state, the insertion rod 14 is inserted into the mounting frame 1 to fix the hand wheel 9, so that the first blade 11 is kept in an upward state. When rubber tapping is required, the staff pulls the insertion rod 14 to slide to the left, and the second spring 16 is deformed. After the insertion rod 14 slides to the left, it no longer blocks the main mounting frame 1. At this time, the staff can control the hand wheel 9 to rotate, and then drive the first blade 11 to rotate downward through the second rotating rod 10. At the same time, the mounting block 15 will also drive the insertion rod 14 to rotate downward. When the first blade 11 is placed on the conveyor belt 8, the staff releases the insertion rod 14. Under the action of the resetting of the second spring 16, the insertion rod 14 slides to the right and is reinserted into the mounting frame 1, thereby fixing the position of the first blade 11 to avoid the first blade 11 rotating and lifting to affect the rubber tapping effect during rubber tapping.

[0031] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes an adjustment component for adjusting the mixing width of the rubber block, the adjustment component includes a third motor 17, a bidirectional screw 18 and a limit block 19, the third motor 17 is fixedly connected to the right rear side of the mounting frame 1, the bidirectional screw 18 is rotatably connected to the rear side of the mounting frame 1, the bidirectional screw 18 is connected to the output shaft of the third motor 17, the upper rear part of the mounting frame 1 is slidably connected to the left and right symmetrical limit blocks 19, and the rear part of the limit block 19 is connected to the bidirectional screw 18 by threads.

[0032] By setting an adjustment component, the width of the rubber block mixed in the rubber mixing roller 4 can be adjusted. The specific operation is as follows: when the rubber block is placed between the front and rear rubber mixing rollers 4 for mixing, the rubber block is located between the left and right limit blocks 19. The rubber block is limited by the limit blocks 19 to prevent the rubber block from being crushed and spreading outward. At the same time, the staff drives the bidirectional screw 18 to rotate through the third motor 17 to drive the limit blocks 19 to slide toward or away from each other, thereby adjusting the distance between the left and right limit blocks 19 to adjust the width of the rubber block mixed in the rubber mixing roller 4.
