Description

Technical Field

[0001] The utility model belongs to the technical field of rubber centering, in particular to a centering device for rubber production. Background Art

[0002] At present, during the production and transportation process, rubber blocks need to be transported by conveyors so as to enter the next process. For example, after the rubber blocks are produced, they need to be transported by conveyors to the next cutting process. During the transportation process, the two ends of the rubber blocks will be uneven, and the two ends of the rubber blocks will not be aligned with the conveying direction of the conveyor. As a result, when the rubber blocks are transported to the cutting process, the rubber blocks are not aligned with the cutting knife, resulting in uneven and inaccurate cutting of the rubber blocks by the cutting knife. Therefore, it is necessary to perform centering operation on the rubber blocks during transportation to ensure that the rubber blocks are in an orderly state during transportation. The existing centering device can only center one rubber block at a time, and the centering efficiency of the rubber blocks is low. Utility Model Content

[0009] Optionally, the area of ​​the two clamping blocks facing each other is larger than the area of ​​the two clamping blocks facing away from each other.

[0010] Through the above technical solution, the design of the areas on both sides of the clamping block makes the clamping block more stable when centering the rubber block, thereby improving the efficiency and quality of the centering.

[0011] Optionally, two bearing seats are mounted on the outer side of the transmission shaft, and the bottom of the bearing seats is fixedly connected to the top of the base plate.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The embodiments of the present application disclose a centering device for rubber production.

[0028] Example

[0029] according to Figures 1 to 5 As shown, a centering device for rubber production includes a base plate 1, pulleys 13 are respectively installed at the four corners of the base plate 1, the top of the base plate 1 is fixedly connected to two parallel and spaced guide rails 2, each guide rail 2 is slidably connected to two sliders 11, the top of each slider 11 is fixedly connected to a support 3, a positioning block 4 is installed between the two supports 3 arranged opposite to each other of the two guide rails 2, the bottom ends of the positioning block 4 are respectively detachably connected to the tops of the two supports 3 by screws, the two positioning blocks 4 are arranged in parallel and spaced, and the tops of the positioning blocks 4 are detachably connected to clamping blocks 5 by screws, and the area of ​​the two clamping blocks 5 facing each other is larger than the area of ​​the side opposite to each other.

[0030] The side of each support 3 is rotatably connected to a connecting rod 6. A dial 7 is rotatably connected between the two connecting rods 6 located on the same guide rail 2. The upper and lower ends of the dial 7 are rotatably connected to the ends of the two connecting rods 6 respectively. The two connecting rods 6 located on the same guide rail 2 are arranged in parallel and spaced apart. The connecting rods 6 are arranged at an angle. The centers of the two dials 7 are fixedly connected to a connecting shaft 8. The center of each dial 7 is fixedly connected to a guide sleeve 14. The two ends of the connecting shaft 8 are respectively inserted into the guide sleeves 14 of the two dials 7, and the ends of the connecting shaft 8 are fixedly connected to the guide sleeves 14. Two rectangular through holes are provided on the top of the base plate 1. The two rectangular through holes correspond one to one with the two dials 7. One end of the dial 7 is located in the rectangular through hole 16. The size of the rectangular through hole 16 does not affect the rotation of the dial 7. The rectangular through hole 16 provides space for the rotation of the dial 7 to prevent the base plate 1 from colliding with the dial 7 when the dial 7 rotates.

[0031] The center sleeve of the connecting shaft 8 is fixedly connected to a swing arm 9, and the lower end of the swing arm 9 is movably connected to a transmission shaft 10. Two bearing seats 12 are sleeved on the outer side of the transmission shaft 10. The bottom of the bearing seat 12 is fixedly connected to the top of the base plate 1. The end of the transmission shaft 10 is connected to the output shaft of the motor. The motor drives the transmission shaft 10 to rotate. The transmission shaft 10 drives the connecting shaft 8 to rotate through the swing arm 9. The connecting shaft 8 drives the two dials 7 to rotate synchronously. During the rotation process, the dial 7 drives the two supports 3 to move toward or away from each other through the two connecting rods 6, thereby realizing the two clamping blocks 5 moving toward each other to clamp the centering rubber block 15, or moving away from each other.

[0032] Working principle:

[0033] The centering device of the present invention is installed at the position where the conveyor needs to be centered, wherein the two clamping blocks 5 are located on both sides of the conveyor belt of the conveyor, and the bottom plate 1 is located below the conveyor. Because the conveyor conveying rubber blocks 15 belong to the existing technology, they are not described here.

[0034] Pulleys 13 are installed at the four corners of the base plate 1 to facilitate movement. Two parallel and spaced guide grooves can be installed under the conveyor, and the base plate 1 can be placed in it so that the pulleys 13 slide in conjunction with the guide grooves, so that the base plate 1 can be flexibly moved to the position where it needs to be centered according to the need for the conveyor to align its position.

[0035] In the initial state, the two clamping blocks 5 are in a state of being away from each other. When the rubber block 15 on the conveyor needs to be centered, the motor is started, and the motor drives the transmission shaft 10 to rotate. The transmission shaft 10 drives the connecting shaft 8 to rotate through the swing arm 9, and the connecting shaft 8 drives the two dials 7 to rotate synchronously. During the rotation process, the dials 7 drive the two supports 3 to move toward each other along the guide rail 2 through the two adjacent connecting rods 6. When the two supports 3 approach each other, they drive the two clamping blocks 5 to approach each other. During the process of approaching each other, the two clamping blocks 5 align the rubber block 15 so that the left and right ends of the rubber block 15 are parallel to the conveying direction of the conveyor. After the centering operation is completed, the motor is started in the reverse direction, and the motor rotates in the reverse direction, driving the transmission shaft 10 to rotate in the reverse direction. The transmission shaft 10 drives the connecting shaft 8 to rotate in the reverse direction through the swing arm 9. The connecting shaft 8 drives the two dials 7 to rotate in the reverse direction synchronously. During the rotation process, the dials 7 drive the two supports 3 to move away from each other along the guide rail 2 through the two adjacent connecting rods 6. When the two supports 3 move away from each other, they drive the two clamping blocks 5 to move away from each other, ready for the next centering operation.
