Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rubber and plastics, and in particular relates to an anti-blocking extrusion tablet press. Background Art
[0002] Rubber and plastic is a general term for the rubber and plastic industries. They are both by-products of petroleum and have the same source. The rubber twin-screw extruder is a commonly used equipment for rubber product companies. The rubber compound refined by the internal mixer is discharged from the discharge port, passes through the material trough of the extruder, and falls between the two screws of the twin-screw extruder due to gravity. The two screws mesh and rotate with each other to extrude the rubber compound to the roller of the sheeting device, and then the two rollers roll against each other to press out a continuous film of a certain thickness.
[0003] At present, when an extrusion tablet press is used, a whole lump of material is usually directly placed into the extrusion tablet press. When a whole lump of material enters the screw hopper, the material is too large to dissipate heat quickly, causing the material to react prematurely. Utility Model Content
[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an anti-blocking extrusion tablet press, which can first cut the whole lump of material into pieces before entering the screw hopper to prevent the material from reacting prematurely because the material is too large and cannot dissipate heat quickly.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an anti-blocking extrusion tablet press, including a cutting chamber and two shredding rollers, the cutting chamber is installed at the input of the extrusion tablet press, and the output port of the cutting chamber is docked with the input of the extrusion tablet press, the two shredding rollers are installed side by side in the cutting chamber, and the cutting chamber is equipped with a driving machine for driving the two shredding rollers to rotate.
[0006] The shredding roller is spirally provided with a first spiral cutter and a second spiral cutter, and the first spiral cutter and the second spiral cutter are arranged in a mirror-symmetrical manner with respect to the center point of the shredding roller.
[0007] The two spiral cutting knives are arranged in a staggered manner.
[0008] The input port of the cutting bin is equipped with a material guide guard plate.
[0009] A material guide bin is installed at the interface between the cutting bin and the extrusion tablet press.
[0010] Two side-by-side chopping rotating columns are vertically and rotatably installed in the material guide bin, and the spiral knives of the two chopping rotating columns are staggered.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model discloses an anti-blocking extrusion tablet press. When in use, a whole lump of material is firstly put into a cutting bin, and two cutting rollers are driven to rotate by a driving machine, so that the whole lump of material is cut into pieces by the two cutting rollers and then enters a screw hopper, so as to prevent the material from reacting prematurely because the material is too large and cannot be quickly cooled.

[0017] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.
[0018] like Figures 1-3 As shown, this embodiment provides an anti-blocking extrusion tablet press, including a cutting chamber 1 and two shredding rollers 2. The cutting chamber 1 is installed at the input of the extrusion tablet press, and the output port of the cutting chamber 1 is docked with the input of the extrusion tablet press. The two shredding rollers 2 are installed side by side in the cutting chamber 1, and the cutting chamber 1 is equipped with a driving machine that drives the two shredding rollers 2 to rotate. Specifically, the two shredding spiral knives are staggered. When in use, first put the whole lump of material into the cutting chamber 1, and drive the two shredding rollers 2 to rotate through the driving machine, so that the whole lump of material is cut into pieces by the two shredding rollers 2, and then enters the screw hopper to prevent the material from reacting prematurely because the material is too large and cannot dissipate heat quickly.
[0019] Furthermore, a first spiral cutter 3 and a second spiral cutter 4 are spirally provided on the shredding roller 2, and the first spiral cutter 3 and the second spiral cutter 4 are arranged in a mirror-symmetrical manner with respect to the center point of the shredding roller 2. When slitting the material, since the first spiral cutter 3 and the second spiral cutter 4 are arranged in a mirror-symmetrical manner with respect to the center point of the shredding roller 2, the material will move toward the two ends of the shredding roller 2 to be cut, so that the material can be cut better.
[0020] Furthermore, a material guide guard plate 5 is installed at the input port of the cutting chamber 1. The material is guided by the material guide guard plate 5 so that the material is stably placed in the cutting chamber 1 for cutting.
[0021] Furthermore, a material guide bin 6 is installed at the interface between the cutting bin 1 and the extrusion tablet press. Specifically, two side-by-side shredding rotating columns 7 are vertically rotatably installed in the material guide bin 6, and the spiral blades of the two shredding rotating columns 7 are staggered. The cut materials enter the material guide bin 6, and the cut materials may also stick to each other during the rolling process, so they continue to be further cut by the two shredding rotating columns 7 to prevent the materials from sticking together during the rolling process.
[0022] The above shows and describes the basic principles and main features of the invention and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the invention, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be defined by the attached claims and their equivalents.
