Description

Technical Field

[0001] This utility model relates to the field of preforming machine technology, specifically a precision preforming machine with a residual adhesive recycling structure. Background Technology

[0002] Preforming machines are one of the equipment used in rubber processing. They enable rubber materials to be pre-formed, facilitating subsequent precision processing, improving work efficiency, reducing processing pressure, and protecting equipment. They are widely used in the rubber processing field, and there are various types of precision preforming machines on the market.

[0003] For example, the utility model with authorization announcement number CN220198515U belongs to the field of preforming technology, specifically a precision preforming machine, including a base. Two sets of support plates are symmetrically welded to the side wall of the extrusion box. A conveyor belt is rotatably installed between the two sets of support plates via a rotating drum. A first air guide plate and a second air guide plate are welded to the fixed plate. Ventilation holes are provided on the side wall of the first air guide plate and the bottom wall of the second air guide plate. The ventilation holes are arranged in an array structure. A first air guide pipe is connected to the side wall of the first air guide plate, and a second air guide pipe is connected to the second air guide plate. Cold air is blown out from the ventilation holes on the first and second air guide plates. As the rubber block falls onto the conveyor belt, it is cooled by the cold air blown out by the first air guide plate. After falling onto the conveyor belt, it is cooled by the cold air blown out by the second air guide plate. This achieves efficient cooling of the rubber block, avoids residual temperature on the rubber block from affecting the next processing step of the rubber block, and is beneficial to improving the cooling efficiency of the rubber block.

[0004] However, based on existing solutions and actual usage, the current precision preforming machine templates are cumbersome to disassemble and assemble, and tend to have residual adhesive inside. Mixing residual adhesive with other processed adhesives will reduce the yield rate, and the cutting force is not uniform enough, resulting in poor flatness of the cut surface. Therefore, we propose a precision preforming machine with a residual adhesive recycling structure to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a precision preforming machine with a residual adhesive recycling structure, so as to solve the problems mentioned in the background art, such as the cumbersome and inconvenient disassembly and assembly of the template of the current precision preforming machine, the easy retention of adhesive inside, the reduction of the yield rate when the residual adhesive is mixed with the processed adhesive, and the uneven cutting force and poor flatness of the cut surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision preforming machine with a residual adhesive recycling structure, comprising:

[0007] A molding box, with a base installed at its bottom;

[0008] Also includes:

[0014] Preferably, the cutting mechanism includes a drive motor, a connecting rod, and a cutting blade. The drive motor is mounted on the top of the base, and the output end of the drive motor is mounted on the connecting rod. The cutting blade is rotatably connected to the left side of the connecting rod.

[0015] Preferably, a first fixing block is integrally provided on the right side of the cutting blade, and a first connecting block is connected to the outer side of the first fixing block via a slot, and the first fixing block is rotatably connected within the first connecting block.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7 This utility model provides a technical solution: a precision preforming machine with a residual adhesive recycling structure, including a molding box 1, a molding template 2, a mounting block 3, a support spring 4, a mounting rod 5, a mounting cap 6, a base 7, a drive motor 8, a connecting rod 9, a cutting blade 10, a first fixing block 11, a first connecting block 12, a fixing frame 13, a second fixing block 14, a second connecting block 15, and a limiting plate 16;

[0032] First, as attached Figure 1 As shown, the rubber material is put into the molding box 1, the molding template 2 is tightly attached to the right side of the molding box 1, the rubber material is extruded from the molding template 2 to form, and a cutting mechanism is provided on the upper right side of the base 7 to prevent uneven cut surfaces and cut the formed rubber.

[0033] As attached Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, the molding template 2 is installed on the molding box 1 through a connecting mechanism that facilitates the recycling of residual adhesive. When it is necessary to clean the residual adhesive in the molding box 1, the molding template 2 is removed from the molding box 1 through the connecting mechanism, and then the molding operation is carried out. The extrusion rod will push the residual adhesive out to avoid the residual adhesive affecting the next operation. The connecting mechanism includes a mounting block 3, a support spring 4, a mounting rod 5, and a mounting cap 6. The outer end of the mounting rod 5 is threaded with the mounting cap 6. Rotating the mounting cap 6 on the mounting rod 5 will disengage the mounting cap 6 from the threaded connection with the mounting rod 5. Then, the mounting rod 5 is pulled out to disengage the mounting rod 5 from the slot connection between the molding template 2 and the mounting block 3. The outer end of the molding template 2 is tightly fitted with the mounting block 3. The support spring 4 is installed on the left side of the mounting block 3. Pushing the mounting block 3 to the left will compress the support spring 4, causing the mounting block 3 to retract into the molding box 1, and the molding template 2 can then be taken out upwards.

[0034] When it is necessary to install the molding template 2, push the mounting block 3 to retract it into the molding box 1. Then, the molding template 2 is tightly fitted with the molding box 1. The elastic action of the support spring 4 pushes the mounting block 3 to reset, so that the mounting block 3 and the molding template 2 are tightly fitted. The cross-section of the mounting block 3 has a "T" shaped structure, which has high stability. The outer end of the molding template 2 has a concave-convex structure. Multiple sets of mounting blocks 3 are distributed at equal angles on the outer side of the molding template 2. Each set of mounting blocks 3 is symmetrically arranged to effectively limit the molding template 2.

[0035] As attached Figure 1 Appendix Figure 2 Appendix Figure 5 and attached Figure 6 As shown, the cutting mechanism includes a drive motor 8, a connecting rod 9, and a cutting blade 10. The drive motor 8, mounted on the upper right side of the base 7, is connected to the output end of the drive motor 8, which in turn drives the connecting rod 9 to rotate at a constant speed. The left side of the connecting rod 9 is rotatably connected to the cutting blade 10, causing the connecting rod 9 to pull the cutting blade 10 to swing. A first fixing block 11 is integrally formed on the right side of the cutting blade 10. When the cutting blade 10 moves, the first fixing block 11 rotates within the first connecting block 12, causing the first connecting block 12 to slide within a fixing frame 13 connected to it in a slot. The fixing frame 13 is fixed to the base. On seat 7, the first connecting block 12 and the cutting blade 10 are limited. A second fixing block 14 is integrally set on the left rear side of the cutting blade 10. The second fixing block 14 is connected to the second connecting block 15 through an external slot. The second fixing block 14 rotates within the second connecting block 15 and drives the second connecting block 15 to move, so that the second connecting block 15 slides within the limiting plate 16 connected to it through the slot. The limiting plate 16 rotates on the molding box 1 to ensure the stability of the cutting blade 10, so that the cutting blade 10 cuts at a uniform speed and applies force evenly to prevent uneven force application from causing uneven cut surfaces of the rubber.
