Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, and in particular to a rubber pretreatment mechanism. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can undergo large deformations under small external forces, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a very large molecular weight, often exceeding hundreds of thousands. The basic manufacturing process of rubber products includes: plasticizing / mixing – calendering, extrusion / extrusion – vulcanization.

[0003] Rubber compound is a sheet-like rubbery substance formed by mixing raw materials and then conveyed to the extruder through a feeding mechanism. However, existing rubber compounds are exposed to the outside environment for a long time during the extruder process, resulting in dust adhering to the rubber compound. During the extrusion operation, the dust mixes with the molten rubber compound, causing the extruded rubber compound to contain impurities and reduce its quality. Furthermore, the sheet-like rubber compound is sheared under the action of the screw inside the extruder, which puts a heavy workload on the screw and is not conducive to long-term production and processing. Therefore, a rubber compound pretreatment mechanism is needed to meet people's needs. Utility Model Content

[0011] Preferably, each of the slide grooves is provided with a guide rod, and the first slider and the second slider in the same slide groove are slidably connected to the outer wall of the guide rod.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, a drive motor causes the first crushing roller to rotate toward the second crushing roller, which in turn drives the drive gear to rotate. The drive gear meshes with the driven gear, causing the driven gear to rotate in the opposite direction to the drive gear. This causes the second crushing roller to rotate toward the first crushing roller, thereby crushing the sheet-like rubber material, reducing its volume, and decreasing the workload of the screw inside the extruder, which is beneficial for long-term production and processing.

[0014] In this invention, the side plate, the first dust-adhesive roller, and the second dust-adhesive roller are arranged so that when the rubber material passes between the first dust-adhesive roller and the second dust-adhesive roller, the first crushing roller and the second crushing roller simultaneously crush the rubber material and drive the rubber material to complete the conveying. The rubber material generates a frictional effect with the first dust-adhesive roller and the second dust-adhesive roller, thereby causing the first dust-adhesive roller and the second dust-adhesive roller to rotate, removing the dust attached to the rubber material and preventing it from entering the extruder, thus improving the extrusion quality.

[0020] 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.

[0021] Reference Figure 1-4 A pretreatment mechanism for adhesive materials includes a housing 1, with both the top and bottom of the housing 1 being open. A first crushing roller 2 and a second crushing roller 3 are rotatably connected inside the housing 1, and the first crushing roller 2 and the second crushing roller 3 are parallel to each other. A motor 4 is provided on one side of the housing 1, and the output end of the motor 4 is connected to one end of the first crushing roller 2. A drive gear 5 and a driven gear 6 are rotatably connected on the other side of the housing 1, and the drive gear 5 and the driven gear 6 mesh with each other. The drive gear 5 is connected to one end of the first crushing roller 2, and the driven gear 6 is connected to one end of the second crushing roller 3. Two side plates 7 are provided on the top of the housing 1, and a first dust-adhesive roller 8 and a second dust-adhesive roller 9 are movably connected between the two side plates 7. The first dust-adhesive roller 8 and the second dust-adhesive roller 9 are parallel to each other and parallel to the first crushing roller 2 and the second crushing roller 3.

[0022] The drive motor 4 causes the first crushing roller 2 to rotate towards the second crushing roller 3, simultaneously driving the drive gear 5 to rotate. The drive gear 5 meshes with the driven gear 6, causing the driven gear 6 to rotate in the opposite direction to the drive gear 5. This causes the second crushing roller 3 to rotate towards the first crushing roller 2, thereby crushing the sheet-like rubber material, reducing its volume, and decreasing the workload of the screw inside the extruder, which is beneficial for long-term production processing. Through the arrangement of the side plate 7, the first dust-adhesive roller 8, and the second dust-adhesive roller 9, when the rubber material passes between the first dust-adhesive roller 8 and the second dust-adhesive roller 9, the first crushing roller 2 and the second crushing roller 3 simultaneously crush the rubber material and drive it to complete the conveying process. The friction between the rubber material and the first dust-adhesive roller 8 and the second dust-adhesive roller 9 causes the first dust-adhesive roller 8 and the second dust-adhesive roller 9 to rotate, removing the dust attached to the rubber material and preventing it from entering the extruder, thereby improving the extrusion quality.

[0023] Specifically, in this embodiment, a collecting hopper 10 is provided at the bottom of the housing 1. The opening of the collecting hopper 10 gradually decreases from top to bottom. The collecting hopper 10 is aligned with the feed inlet of the extruder, which helps to concentrate the feeding of the crushed rubber material.

[0024] Specifically, in this embodiment, a plurality of support legs 11 are provided on the outer wall of the hopper 10, and mounting holes 12 are provided on the bottom end of the support legs 11 for installing and fixing the pretreatment mechanism at the feed inlet of the extruder.

[0025] Specifically, in this embodiment, several torsion spring hinges 13 are provided on the top of both sides of the box 1. The same sealing plate 14 is provided on several torsion spring hinges 13 on each side. The sealing plate 14 can prevent the adhesive from splashing during the crushing process. In addition, the rebound force of the torsion spring hinges 13 makes the two sealing plates 14 always in an upward rotation trend, which has a clamping effect on the adhesive and prevents the adhesive from breaking and moving out of the box 1 during the crushing process.

[0026] Specifically, in this embodiment, each of the two side plates 7 is provided with a sliding groove 15, and a first slider 16 and a second slider 17 are slidably connected in each sliding groove 15. The first dust-adhesive roller 8 is rotatably connected between the two first sliders 16, and the second dust-adhesive roller 9 is rotatably connected between the two second sliders 17, so that the distance between the first dust-adhesive roller 8 and the second dust-adhesive roller 9 is adjustable.

[0027] Specifically, in this embodiment, each slide 15 is provided with a spring 18 at both ends. The spring 18 is connected to the first slider 16 and the second slider 17 at the corresponding positions. The rebound force after the spring 18 is compressed increases the friction between the first sticky roller 8 and the second sticky roller 9 on the adhesive material, thereby improving the sticking effect.

[0028] Specifically, in this embodiment, each slide groove 15 is provided with a guide rod 19, and the first slider 16 and the second slider 17 in the same slide groove 15 are slidably connected to the outer wall of the guide rod 19 to prevent the first slider 16 and the second slider 17 from disengaging from the slide groove 15.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
