Description

Technical Field

[0001] This utility model relates to the field of color sorting equipment, and in particular to a material guide plate structure for a color sorting machine. Background Technology

[0002] The material inside the color sorter needs to be fed evenly and at a constant speed into the testing mechanism to ensure that the material meets the working conditions of the testing mechanism and does not cause material accumulation that affects the testing structure.

[0003] Most existing conveying methods use inclined pipes to move materials by their own weight. However, this method of movement is relatively uncontrollable, and different materials move in different ways. Some materials may accumulate on one side during the rolling process, resulting in uneven distribution of materials and affecting subsequent processing. Utility Model Content

[0004] The purpose of this invention is to provide a material guide plate structure for a color sorter, which solves the problem of uncontrollable material movement during the process, resulting in uneven material distribution and directly affecting subsequent processing.

[0005] To solve the problems of the prior art, the technical solution of this utility model is as follows: A material guide plate structure for a color sorter includes a pipeline for guiding materials. A base plate is horizontally placed inside the pipeline. Two fixed rollers are symmetrically rotated at the top of the base plate, and two movable rollers are symmetrically arranged at the bottom of the base plate. The portion of the fixed rollers extending to the outside of the pipeline is connected to a motor via a transmission belt. A first spring rod is arranged between the movable rollers and the base plate, and the first spring rod applies a downward elastic force to the movable rollers. A push plate is arranged between the base plate and the fixed rollers. A second spring rod is arranged between the push plate and the base plate, and the second spring rod applies an upward pushing force to the push plate. A belt is sleeved on the outside of the movable rollers, fixed rollers, and push plate, and a deformable material passage gap is left between the belt and the bottom of the pipeline.

[0006] Furthermore, the spacing between the two fixed rollers and the two movable rollers is adapted to the width of the substrate to ensure that the belt between the fixed rollers and the movable rollers has sufficient length to ensure the restriction and guidance of the material.

[0007] Furthermore, two support rollers are horizontally placed inside the pipeline. The two support rollers are respectively set on the left and right sides of the substrate and are flush with the substrate. The belt wraps around the support rollers to form an inclined slope on the left and right sides of the substrate, which guides the material and makes it easier for the material to enter the gap between the pipeline and the belt.

[0008] Furthermore, the thrust of the first spring rod is greater than that of the second spring rod, ensuring that the second spring rod will not pull the belt, causing the movable roller to retract.

[0009] Furthermore, the bottom surface inside the pipeline is provided with guide patterns along the material conduction direction to guide the direction of the material, restrict the movement path of the material, and prevent the material from deviating during movement.

[0010] Furthermore, the push plate is an upwardly convex arc-shaped plate structure, and the convex part of the push plate is higher than the fixed rollers on both sides, so that the push plate can effectively push the belt upward and ensure that the belt is always subjected to thrust.

[0011] Furthermore, each of the two fixed rollers is equipped with a pulley at its end. The motor is synchronously connected to the pulleys of the two fixed rollers via a transmission belt, so that the motor can drive the two fixed rollers to rotate simultaneously, thereby smoothly driving the belt to move.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting textures on the inside of the pipeline, the movement path of the material is basically restricted by the textures. At the same time, a fixed roller drives the belt to rotate along the movement direction of the material on the side close to the textures. The belt drives the material to move along the textures. At this time, the bottom of the material is restricted by the textures and the top is restricted by the belt, so there will be no change in position.

[0014] 2. When excessive material enters between the textured part and the belt, it will push the belt upward. When the bottom of the belt is pushed upward, the top of the belt is pulled downward. The pull pushes the push plate to squeeze the second spring rod and deforms it, allowing the belt to deform and avoiding excessive compression and damage to the material. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1-3As shown, a material guide plate structure for a color sorter includes a pipe 1 for guiding materials. The bottom surface of the pipe 1 is provided with guide patterns along the material conduction direction to guide the direction of the materials, restrict the movement path of the materials, and prevent the materials from deviating during movement.

[0021] Inside the pipeline 1, a base plate 2 is placed horizontally. Two fixed rollers 3 are symmetrically rotated on the top of the base plate 2, and two movable rollers 4 are symmetrically arranged on the bottom of the base plate 2. The distance between the two fixed rollers 3 and the two movable rollers 4 is adapted to the width of the base plate 2 to ensure that the belt 8 between the fixed rollers 3 and the movable rollers 4 has sufficient length to ensure the restriction and guidance of materials. The part of the fixed rollers 3 extending to the outside of the pipeline 1 is connected to a motor 10 via a transmission belt. A first spring rod 5 is arranged between the movable rollers 4 and the base plate 2. The first spring rod 5 applies a downward elastic force to the movable rollers 4. A push plate 6 is arranged between the base plate 2 and the fixed rollers 3. The push plate 6 is an upwardly raised arc-shaped plate structure, and the raised part of the push plate 6 is higher than the fixed rollers 3 on both sides, so that the push plate 6 can effectively push the belt 8 upward to ensure that the belt 8 is always subjected to pushing force. A second spring rod 7 is arranged between the push plate 6 and the base plate 2. The second spring rod 7 applies an upward pushing force to the push plate 6.

[0022] A belt 8 is fitted around the movable roller 4, the fixed roller 3, and the push plate 6. A deformable material passage gap is left between the belt 8 and the bottom of the pipe 1. Two support rollers 9 are horizontally placed inside the pipe 1. The two support rollers 9 are respectively set on the left and right sides of the base plate 2 and are flush with the base plate 2. The belt 8 wraps around the support rollers 9 to form an inclined slope on the left and right sides of the base plate 2 to guide the material and make it easier for the material to enter the gap between the pipe 1 and the belt 8. The thrust of the first spring rod 5 is greater than that of the second spring rod 7, ensuring that the second spring rod 7 will not pull the belt 8 and cause the movable roller 4 to retract. The ends of the two fixed rollers 3 are provided with pulleys. The motor 10 is synchronously connected to the pulleys of the two fixed rollers 3 through a transmission belt, so that the motor 10 can drive the two fixed rollers 3 to rotate at the same time, thereby smoothly driving the belt 8 to move.

[0023] Working principle description: First, when in use, the material enters the pipe 1, and at the same time, the motor 10 drives the fixed roller 3 to rotate. When the fixed roller 3 rotates, it drives the belt 8 to move. At the same time, the belt 8 drives the movable roller 4 to rotate. At this time, the belt 8 circulates along the movable roller 4, the support roller 9 and the fixed roller 3. During the movement, the material moves in the pipe 1. If there is too much material in the pipe 1 or a different material is changed, the material squeezes the belt 8 and pushes it upward between the belt 8 and the pipe 1. When the belt 8 is pushed, it drives the movable roller 4 to move upward, ensuring that the material passage gap between the belt 8 and the pipe 1 meets the material movement requirements. At this time, the limiting force of the belt 8 on the push plate 6 is reduced, and the second spring rod 7 extends to push the push plate 6 to move upward and keep it in contact with the belt 8, ensuring that the belt 8 maintains a certain tension.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
