Technical Field

[0001] The utility model relates to the technical field of transmission belt production equipment, and more specifically to a transmission belt raw material sheeting and regularizing device. Background Art

[0002] In the prior art, during production, a transmission belt is made of layers of composite raw material sheets through a vulcanization process. The raw material sheets are formed by extruding the prepared rubber raw materials through multiple heated rollers. There is a height difference between the two rollers for preliminary sheeting. The raw material falls from above the two rollers and falls between the two rollers. The raw material is extruded by heating and rotating the two rollers. However, during production, the raw material on the rollers will be squeezed toward the two ends of the rollers as the rollers rotate, resulting in a lack of raw material in the middle of the roller. The general solution is to manually use tools to shovel the raw material that runs to the two ends of the roller back to the middle of the roller. However, manual shoveling will pose a safety hazard, and improper use of tools will scratch the surface of the roller. Therefore, a technical solution is needed to solve the above problem.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1 As shown, this embodiment discloses a transmission belt raw material sheeting regularization device, which is used for regularizing the raw material 8 being squeezed between the first pressing roller 4 and the second pressing roller 5, the raw material 8 falls downward from the discharge port 6 between the first pressing roller 4 and the second pressing roller 5, the position of the second pressing roller 5 is higher than the first pressing roller 4, and the raw material sheet 81 is squeezed and sent out with the rotation of the first pressing roller 4 and the second pressing roller 5. This embodiment includes a push plate 1, a drive box 2, and a connecting rod 3. The drive box 2 is fixedly mounted on a bracket 7 located on one side of the first pressing roller 4, and the upper end surface of the bracket 7 is flush with the uppermost end of the first pressing roller 4. There are two push plates 1, and the push plates 1 are perpendicular to the central axis of the first pressing roller 4. The front end of the push plate 1 is close to the second pressing roller 5, and the lower end of the push plate 1 is close to the first pressing roller 4. There is no contact between the push plate 1 and the first pressing roller 4 and the second pressing roller 5, and there is a gap between the push plate 1 and the first pressing roller 4 and the second pressing roller 5 for the raw material 8 to squeeze through.

[0022] like Figure 1 , Figure 2As shown, the push plate 1 is fixedly installed on the connecting rod 3, and the driving box 2 includes two screw rods 22, two motors 21, a guide rod 23, and a box body 24. The two motors 21 drive the two screw rods 22 to rotate, and the two push plates 1 can approach or move away from each other. The motor 21 is driven by a belt and a pulley. The ends of the two screw rods 22 that are close to each other are inclined toward the direction away from the push plate 1. A part of the connecting rod 3 extends into the driving box 2, and the guide rod 23 is arranged parallel to the screw rod 22. The connecting rod 3 includes a connecting sleeve 35. The screw rod 22 penetrates the connecting sleeve 35 and is threadedly connected to the connecting sleeve 35. The guide rod 23 penetrates the connecting sleeve 35. The motor 21 drives the screw rod 22 to rotate so that the connecting rod 3 can move along the screw rod 22. The guide rod 23 plays a role of guiding and limiting rotation. When the two push plates 1 approach each other, the raw materials 8 accumulated at both ends of the first pressing roller 4 can be pushed to the center position of the first pressing roller 4 to prevent the raw materials 8 from accumulating at both ends of the first pressing roller 4.

[0023] like Figure 2 , Figure 3 As shown, the side wall of the box body 24 facing the push plate 1 has the same inclination angle as the screw rod 22. A guide channel 241 is provided on the end face of the box body 24 facing the push plate 1. The guide channel 241 is arranged parallel to the screw rod 22. The connecting rod 3 passes through the guide channel 241. The connecting rod 3 is provided with a sliding sleeve 32. The outer wall of the sliding sleeve 32 is provided with two parallel ring plates 321. An annular groove 322 is formed between the two ring plates 321. The edge of the guide channel 241 is inserted into the annular groove 322. The sliding sleeve 32 can clamp the upper and lower edges of the guide channel 241, which plays a role in stabilizing and guiding the connection between the connecting rod 3 and the guide channel 241. The connecting rod 3 can move along the guide channel 241. The side wall of the box body 24 facing the push plate 1 has the same inclination angle as the screw rod 22, which ensures that the position of the sliding sleeve 32 on the connecting rod 3 does not change. When the connecting rod 3 moves, the sliding sleeve 32 can move along the guide channel 241.

[0024] More preferably, an outer wall of the sliding sleeve 32 is provided with an extension plate 323, and the extension plate 323 extends in a direction away from the push plate 1, and the extension plate 323 is in contact with the outer surface of the box body 24. The connecting rod 3 includes a main rod 31 and a support rod 33. The main rod 31, the support rod 33, and the extension plate 323 form a triangular support. Since the push plates 1 will be subjected to the force of squeezing the raw materials 8 toward the two ends of the first pressing roller 4 when approaching each other, in order to ensure the stability of the support of the connecting rod 3, the support rod 33 is installed at the opposite position of the connecting rod 3 where the push plate 1 is installed. The support rod 33 is installed obliquely, and the other end of the support rod 33 is fixed on the extension plate 323. The support rod 33 supports the part of the connecting rod 3 where the push plate 1 is installed, so that the push plate 1 is more stable.

[0025] like Figure 1As shown, more preferably, the connecting rod 3 is installed with a reinforcing rod 34, the reinforcing rod 34 is fixedly connected to the side wall of the push plate 1, the reinforcing rod 34 is vertically arranged to the connecting rod 3, the reinforcing rod 34 is arranged along the length direction of the connecting rod 3, and the reinforcing rod 34 extends along the height direction of the push plate 1. The reinforcing rod 34 supports the outer side surface of the push plate 1 to prevent the push plate 1 from deforming when pushing the raw material 8.

[0026] like Figure 2 , Figure 4 As shown, when the two push plates 1 approach each other, the push plates 1 gradually approach the driving box 2, and when the two push plates are farthest apart, the distance between the push plates 1 and the second pressing roller 5 is L1, and when the distance between the two push plates 1 is closest, the distance between the push plates 1 and the second pressing roller 5 is L2, and L2 is greater than L1. When the two push plates 1 approach each other, L1 gradually increases to L2, and the gap between the push plates 1 and the second pressing roller 5 will gradually increase, so that after the raw material 8 is pushed, a part of it can be pressed to the two ends of the first pressing roller 4 as the first pressing roller 4 and the second pressing roller 5 roll, thereby ensuring that the raw material 8 is evenly distributed on the first pressing roller 4.

[0027] like Figure 1 As shown, more preferably, the push plate 1 is installed with a material baffle plate 11, and the material baffle plate 11 is located on the side of the lower end of the push plate 1 close to the drive box 2. When the two push plates 1 are close to each other, the raw material 8 coming out of the discharge port 6 will fall between the two push plates 1 to prevent the raw material 8 from accumulating too much and falling from between the first pressing roller 4 and the bracket 7. The material baffle plate 11 that can receive the raw material 8 is provided to prevent the raw material 8 from falling off the first pressing roller 4.

[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
