Description

Technical Field

[0001] This application relates to the technical field of raw material processing, and particularly relates to a mixer for rubber product production raw materials and a usage method thereof. Background Art

[0002] Rubber products refer to various rubber products produced from natural and synthetic rubbers. In the production process of rubber products, in order to improve some properties of rubber products, one or more auxiliary materials need to be added to rubber raw materials. Therefore, a mixer for rubber product processing and production is required. Common mixers usually consist directly of a mixing cylinder and a stirring rod mechanism. The stirring rod of the stirring mechanism extends into the mixing cylinder to stir the raw materials.

[0003] Common rubber product processing requires the addition of vulcanizing agent materials. Since the vulcanizing agent materials are in a solid state, they must be fully stirred and mixed evenly with the rubber raw materials. Moreover, the rubber raw materials themselves have a certain viscous property, which is usually between solid and liquid states, so they are not completely fluid. Therefore, it is very difficult to stir them all as a whole by conventional stirring methods. It takes a lot of time to stir them evenly. Through the mixing means of stirring, the raw materials cannot be fully rolled and "molded", so that some corresponding auxiliary raw materials added are difficult to be fully dispersed and made even, resulting in poor mixing effect between the raw materials and some corresponding auxiliary materials. Summary of the Invention

[0004] The purpose of this application is to provide a mixer for rubber product production raw materials and a usage method thereof to solve the problems in the above background art.

[0005] Specifically, this application adopts the following technical solutions to achieve the above purpose:

[0006] A mixer for rubber product production raw materials, comprising:

[0007] A machine body and a cover plate. The machine body has a placement groove for accommodating raw materials, and the cover plate is used to cover the placement groove;

[0008] An extrusion plate slidably arranged in the placement groove and through holes opened on the extrusion plate. The extrusion plate divides the placement groove into two rolling areas, and the two rolling areas are connected through the through holes. The number of the through holes is at least two and is symmetrically distributed on two side edges of the extrusion plate;

[0009] A blocking assembly arranged at the extrusion plate. The raw materials flow unidirectionally through the through holes under the action of the blocking assembly, and the acting directions of the two blocking assemblies are opposite;

[0010] A driving assembly arranged on the machine body. The extrusion plate slides under the action of the driving assembly.

[0011] Further, at least two guide rollers are constructed in the placement groove, and the two guide rollers are arranged in parallel. Two sleeves are constructed through the pressing plate, and the two sleeves are respectively sleeved on the two guide rollers in a sliding manner.

[0012] Further, a plurality of reinforcing plates are constructed on both side surfaces of the pressing plate. The plurality of reinforcing plates are uniformly distributed on the periphery of the sleeve, are connected to the sleeve, and extend along the direction away from the sleeve to the edge of the pressing plate. At least one of the reinforcing plates is connected between the two sleeves.

[0013] Further, the guide roller has a hollow structure to form a hollow cavity extending along its own length direction. The driving assembly includes an iron core column fixedly arranged in the hollow cavity and coaxial with it, and a winding arranged on the iron core column and extending along its length direction. It further includes a magnet fixedly arranged on the sleeve, and the magnetic pole direction thereof is parallel to the length direction of the iron core column.

[0014] Further, the magnet is arranged in a ring shape and is embedded in the wall of the sleeve and is coaxial with the sleeve to form a ring sleeve around the iron core column.

[0015] Further, a rotating rod is rotatably arranged on the machine body. A spiral groove is constructed on the rotating rod and is distributed along the length direction of the rotating rod. A sliding block is slidably arranged on the machine body, and its sliding direction is consistent with the length direction of the rotating rod and forms a sleeve around it and meshes with the spiral groove. The sliding block and the pressing plate are magnetically attracted and matched. An air guide pipe is fixedly arranged on the machine body, and one end of it is communicated with the hollow cavity. A spiral blade is fixedly arranged on the rotating rod and is located inside the port of the air guide pipe.

[0016] Further, the air guide pipe at least includes a first section, a second section and a third section along its own length direction. The first section is communicated with the hollow cavity. The diameter of the third section is at least twice that of the first section. The second section communicates the first section and the third section, and its diameter gradually decreases from the end close to the third section to the end close to the first section. The spiral blade is located at the third section and its circumferential diameter is larger than the diameter of the first section.

[0017] Further, the blocking assembly includes a plurality of parallel connecting columns constructed at the edge of one side of the through hole, and a circular plate for covering the through hole. The plurality of connecting columns slidably penetrate through the circular plate, and a limiting end is constructed at the free end of the connecting column.

[0018] Further, a plurality of partition plates are constructed inside the through hole, and cutting edges acting on the raw materials are constructed thereon and face the side where the raw materials enter the through hole.

[0019] Regarding a mixer for rubber product production raw materials described above, its usage method includes the following steps:

[0020] S1. Put the rubber raw materials and auxiliary materials to be mixed into the placement groove, and cover the placement groove with a cover plate;

[0021] S2. Start the drive assembly to make the extrusion plate slide reciprocally in the placement groove, so that the space in the two rolling areas changes cyclically, thereby cyclically rolling the raw materials. Through the blocking assembly, the raw materials flow cyclically in the two rolling areas to mix the raw materials and auxiliary materials;

[0022] S3. When the mixing is completed, remove the cover of the cover plate and take out the raw materials.

[0023] The beneficial effects of this application are as follows:

[0024] Through the setting of the drive assembly in this application, the extrusion plate is continuously reciprocally slid inside the placement groove, so that the raw materials are continuously squeezed back and forth in the two rolling areas. With the cooperation of the blocking assembly, the raw materials flow directionally through the through holes, so that the raw materials continuously flow in the same posture, so that the auxiliary raw materials are fully mixed under the rolling action. Compared with the existing stirring type mixing, this equipment can continuously roll and "torture" the whole raw materials during work, and there is a great improvement in the final mixing uniformity.

[0025] Through the setting of the guide roller and the sleeve in this application, the extrusion plate can maintain a good stability relying on the cooperation between the two during sliding, thereby reducing the movement resistance and better squeezing the rubber raw materials fully.

[0026] Through the structure of the reinforcing plate in this application, the firmness of the connection between the extrusion plate and the sleeve can be increased, thereby increasing the strength of the whole extrusion plate and at the same time better increasing the stability of the extrusion plate during sliding.

[0027] Through the iron core column and the winding wound around it in this application, when the winding is energized, the iron core column will generate magnetism. The north-south direction of the magnetism is consistent with the length direction of the iron core column and cooperates with the magnet on the sleeve, so that a driving force consistent with the length direction of the iron core column can be generated on the magnet to drive the extrusion plate to slide. By changing the current direction of the winding, the extrusion plate can be controlled to slide back and forth in two directions. Compared with the conventional method, this driving method can realize an air-gap type induction drive, so that the direct participation of mechanical structures is not required, the movement resistance can be effectively reduced, and the driving efficiency is relatively high. In addition, since there is no direct mechanical movement generated, the noise of the whole equipment during work is also relatively small. Description of the Drawings

Embodiment

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0036] As Figures 1-6 shown, a rubber product production raw material mixer proposed in an embodiment of the present application at least includes:

[0037] A body 1 and a cover plate 2, the body 1 has a placement groove 3 for accommodating raw materials, the cover plate 2 is used to cover the placement groove 3, the placement groove 3 is square, and the cover plate 2 can be specifically hinged at the edge of the placement groove 3 and is configured with a buckle lock;

[0038] An extrusion plate 4 slidably arranged in the placement groove 3 and a through hole 5 opened on the extrusion plate 4, the extrusion plate 4 divides the placement groove 3 into two rolling areas 6, the two rolling areas 6 are communicated through the through hole 5, the number of the through holes 5 is at least two and is symmetrically distributed at two side edges of the extrusion plate 4;

[0039] The blocking component 7 is arranged at the extrusion plate 4. Under the action of the blocking component 7, the raw material flows unidirectionally through the through hole 5, that is, under the action of the blocking component 7, the raw material can only flow from one side of the through hole 5 to the other side, and vice versa, similar to the principle of a one-way valve. Moreover, the acting directions of the two blocking components 7 here are opposite, so the flowing directions of the raw material through the two through holes 5 are opposite;

[0040] The driving component 8 is arranged on the machine body 1. The extrusion plate 4 slides under the action of the driving component 8;

[0041] Based on the above features, during use, the raw material and the auxiliary materials to be mixed are put into the placement groove 3 together. Hereinafter, the raw material and the auxiliary materials are collectively referred to as the mixed material. The driving component 8 is used to make the extrusion plate 4 slide extremely reciprocally, so that the mixed material is continuously extruded, and thus continuously flows in the two rolling areas 6. Through the action of the through hole 5 and the blocking component 7, when the mixed material is rolled from one rolling area 6 to the other rolling area 6, the raw material can only flow through one of the designated through holes 5. When it is rolled back from the other rolling area 6, it can only flow through the other observation hole. Thus, it is equivalent to that when the mixed material is being rolled, it continuously flows in a loop, so as to continuously break up the substances in the mixed material. Compared with the existing mixing method of stirring, when this machine is working, the whole raw material is constantly being "roughed up", while the traditional stirring can only agitate part of the raw material, and due to its viscous nature, the raw material is not easily dispersed, while the overall rolling is not likely to have this situation, and the mixing effect is better.

[0042] Such as Figure 3 and Figure 4 As shown in the figure, in some embodiments, the sliding mode of the extrusion plate 4 is as follows. At least two guide rollers 9 are constructed in the placement groove 3. The two guide rollers 9 are arranged in parallel. Two sleeves 10 are penetrated and constructed on the extrusion plate 4. The two sleeves 10 are respectively slidably sleeved on the two guide rollers 9, so as to realize the linear movement mode of the extrusion plate 4. The cooperation between the sleeve 10 and the guide roller 9 makes the extrusion plate 4 have a better stable effect when sliding.

[0043] Such as Figure 6 As shown in the figure, in some embodiments, a plurality of reinforcing plates 11 are constructed on both sides of the extrusion plate 4. The plurality of reinforcing plates 11 are evenly distributed on the periphery of the sleeve 10 and are connected to the sleeve 10, and extend along the direction away from the sleeve 10 to the edge of the extrusion plate 4, so that you can better maintain the connection strength between the sleeve 10 and the plate body of the extrusion plate 4. And at least one of the reinforcing plates 11 is connected between the two sleeves 10, so that the two sleeves 10 also have good integrity, thereby increasing the stable effect.

[0044] Such asFigure 4 As shown, in some embodiments, the guide roller 9 is hollow to form a hollow tube cavity 12 extending along its length direction, and the driving assembly 8 includes an iron core column 13 fixedly arranged in the hollow tube cavity 12 and coaxial therewith, and a winding 14 arranged on the iron core column 13 and extending along its length direction, and also includes a magnet 15 fixedly arranged on the sleeve 10, and the direction of its magnetic pole is parallel to the length direction of the iron core column 13;

[0045] Based on the above characteristics, when the winding 14 is energized, the entire core column 13 generates a magnetic force whose direction is consistent with its own length direction, so that the magnet 15 will generate a magnetic thrust when subjected to the magnetic force, thereby moving the sleeve 10 and thus moving the extrusion plate 4. This driving method achieves an effect of transmission through air, making the process simple and smooth, thereby reducing the mechanical resistance encountered during movement and making the extrusion plate 4 move more smoothly.

[0046] like Figure 5 As shown, Figure 5 1 is a schematic diagram showing that a portion of the sleeve 10 and the extrusion plate 4 are cut out as a whole. In some embodiments, the magnet 15 is arranged in an annular shape and is buried in the wall of the sleeve 10. Figure 5 As shown, the magnet 15 is coaxial with the sleeve 10 to form a ring sleeve for the core column 13. This method can protect the magnet 15 and at the same time, the ring sleeve can better contact the magnetic force of the core column 13.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, a rotating rod 16 is rotatably provided on the machine body 1, and a spiral groove 17 is constructed on the rotating rod 16 and distributed along the length direction of the rotating rod 16. A sliding block 18 is slidably provided on the machine body 1, and the sliding mode of the sliding block 18 is specifically realized by constructing a guide rail on the machine body 1, and its sliding direction is consistent with the length direction of the rotating rod 16, and it is sleeved and meshed with the spiral groove 17. The sliding block 18 and the extrusion plate 4 are magnetically matched, and an air duct 19 is fixedly provided on the machine body 1, and one end of the air duct 19 is connected to the hollow tube cavity 12, and a spiral leaf 20 located in the port of the air duct 19 is fixedly provided on the rotating rod 16, and the magnetic attraction between the sliding block 18 and the extrusion plate 4 can be achieved by burying permanent magnets in the materials of both.

[0048] Based on the above characteristics, when the extrusion plate 4 moves, the slider 18 is synchronously moved by the magnet 15, so that the rotating rod 16 rotates under the action of the spiral groove 17 and drives the spiral blade 20 to rotate, thereby generating an air current in the air duct 19 to blow towards the inside of the hollow cavity 12, so as to dissipate heat from the iron core column 13 and the winding 14.

[0049] As Figure 1 shown, in some embodiments, the air duct 19 includes at least a first section 21, a second section 22, and a third section 23 along its length. The first section 21 communicates with the hollow cavity 12. The diameter of the third section 23 is at least twice that of the first section 21. The second section 22 communicates with the first section 21 and the third section 23, and its diameter gradually decreases from the end close to the third section 23 to the end close to the first section 21. The spiral blade 20 is located at the third section 23 and has a circumferential diameter larger than the diameter of the first section 21. When the spiral blade 20 rotates, the generated air current will enter the second section 22. Due to the structure of its diameter, the air current will be squeezed, so that the pressure will increase after entering the first section 21, thereby increasing the speed. Therefore, this design makes the air current enter the hollow cavity 12 from one side of the air duct 19, which will increase the wind speed and thus enhance the heat dissipation effect.

[0050] As Figure 6 shown, in some embodiments, the blocking assembly 7 includes a plurality of parallel connecting columns 24 constructed at the edge of one side of the through hole 5, and a circular plate 25 for covering the through hole 5. The plurality of connecting columns 24 slidably penetrate through the circular plate 25, and a limiting end is constructed at the free end of the connecting column 24. Therefore, when the raw material enters the through hole 5 from one side of the connecting column 24, it will squeeze the circular plate 25, so that the circular plate 25 covers the through hole 5. When moving in the other direction, the situation where the circular plate 25 covers the through hole 5 will not occur, thus achieving the effect of one-way blocking.

[0051] As Figure 6 shown, in some embodiments, a plurality of partition plates 26 are constructed inside the through hole 5, and cutting edges 27 acting on the raw material are constructed thereon and face the side where the raw material enters the through hole 5. This design enables the raw material to be cut open by the cutting edges 27 when passing through the through hole 5, thereby promoting the dispersion of the raw material.

[0052] Regarding the rubber product production raw material mixer provided in the above embodiments, the present embodiment also provides its usage method, which at least includes the following steps:

[0053] S1. Put the rubber raw material and the auxiliary materials to be mixed into the placement groove 3 and cover the placement groove 3 with the cover plate 2;

[0054] S2. Start the driving component 8 to make the extrusion plate 4 slide reciprocally in the placement groove 3, so that the space in the two rolling areas 6 changes cyclically, thereby rolling the raw materials cyclically.

[0055] S3. When the mixing is completed, remove the cover of the cover plate 2 and take out the raw materials.

[0056] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
