Description

Technical Field

[0001] This utility model belongs to the field of granulation equipment technology, and more specifically, it relates to a granulator for thermoplastic dynamic vulcanized elastomers. Background Technology

[0002] Thermoplastic dynamic vulcanized elastomers, as composite materials in which the rubber phase is dispersed in a thermoplastic resin matrix after dynamic vulcanization, combine the elastic recovery of rubber with the thermal processability of plastics. They are widely used in automotive seals, electronic device protective sleeves, pipe fittings and other fields. Granulation is the core post-processing step in the production of vulcanized elastomers. The uniformity of particle size, surface smoothness and purity of the particles directly determine the molding quality of subsequent injection molding, extrusion and other processing.

[0003] Current vulcanized elastomer granulators still have the following shortcomings:

[0004] The molten material of vulcanized elastomer is highly viscous. During underwater pelletizing, the molten material tends to adhere to the blade surface and gradually accumulate, resulting in a decrease in the blade edge fit. If not cleaned in time, it will cause uneven cutting of the material strip, producing phenomena such as tailing pellets and burr pellets. Current equipment lacks a continuous automatic cleaning structure for the blades, requiring additional screening and rework processes, which reduces production efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a granulator for thermoplastic dynamic vulcanized elastomers, which solves the problem mentioned in the background art that during underwater pelletizing, molten material easily adheres to the blade surface and gradually accumulates. Current equipment lacks a continuous automatic cleaning structure for the blades, requiring additional screening and rework processes, thus reducing production efficiency.

[0006] The purpose and effect of this utility model of a granulator for thermoplastic dynamic vulcanized elastomer are achieved by the following specific technical means:

[0007] A granulator for thermoplastic dynamic vulcanized elastomers includes: a base; the base adopts a rectangular plate structure; a water tank with a rectangular groove structure is fixedly provided on the front side of the base, and the inner wall of the water tank has four sets of through circular groove structures in a rectangular array; a mounting plate with a U-shaped plate structure is fixedly provided inside the water tank, and a through circular groove structure is provided on one side of the mounting plate; a mold cavity is fixedly provided in the circular groove of the mounting plate; a set of cylindrical connecting rods is fixedly provided on both sides of the top of the mounting plate, and springs are sleeved on the outer sides of both ends of the connecting rods; a set of rectangular block cleaning blocks is slidably provided on both sides between the two sets of connecting rods, and the bottom of the cleaning blocks has an inclined structure.

[0008] Furthermore, a rectangular groove structure of a feeding trough is fixedly provided on the top rear side of the base; a set of stirring rollers is rotatably arranged on both sides inside the feeding trough, and a spiral structure is provided on the outer side of the stirring rollers; a set of first motors is fixedly arranged on both sides of the top of the feeding trough, and the first motors are drivenly connected to the stirring rollers; a cylindrical structure of a conveying trough is fixedly provided on the top rear side of the base, and a rectangular through-slot structure is opened on the top of the conveying trough, and the rectangular through-slot on the top of the conveying trough is connected to the feeding trough; a conveying roller is rotatably arranged inside the conveying trough; a second motor is fixedly arranged on one side of the top of the base, and the second motor is drivenly connected to the conveying roller.

[0009] Furthermore, a blade is rotatably mounted inside the water tank, and the surface of the blade is in contact with the front surface of the mold cavity; a third motor is fixedly mounted inside the water tank, and the third motor is connected to the blade for transmission.

[0010] Furthermore, a set of cylinders is fixedly installed on both sides of the interior of the water tank; a bottom groove with a rectangular groove structure is fixedly installed on the front bottom of the water tank.

[0011] Furthermore, a set of cylindrical sliding rods are slidably installed in the circular through grooves around the inner wall of the water tank, and the sliding rods are connected to the cylinder for transmission; the bottom of the four sets of sliding rods is fixedly connected to a rectangular groove structure collection tank, and the outer wall of the collection tank is in contact with the inner wall of the bottom tank, and a filter hole structure is opened on the outer side of the collection tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] During the rotation of the blade, the cleaning block can be pushed open. Under the action of the spring force, the inner wall of the cleaning block is always in close contact with the blade surface, scraping off the molten material that is stuck together in real time. This avoids the accumulation of material on the blade edge, which affects the cutting accuracy. The surface smoothness of the particles is greatly improved, and the phenomena such as product adhesion and burrs are reduced, which greatly improves product quality and production efficiency.

[0014] This invention uses a cylinder to drive a slide rod to raise and lower the collection tank. The cut particles fall directly into the collection tank that is submerged in water. After collection, the cylinder drives the collection tank to rise above the water surface. The filter structure enables rapid dehydration. The close fit design between the collection tank and the bottom tank prevents particles from scattering. The lifting process is precisely controlled by the cylinder, making it easy to operate and highly efficient in collecting particles. The efficiency of collecting a single batch is greatly improved, while reducing the intensity of manual labor. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides a granulator for thermoplastic dynamic vulcanized elastomers, comprising: a base 1; the base 1 adopts a rectangular plate structure; a rectangular groove structure water tank 107 is fixedly provided on the front side of the base 1, and the inner wall of the water tank 107 has four sets of through circular slot structures in a rectangular array for installing slide rods 113; a U-shaped plate structure mounting plate 108 is fixedly provided inside the water tank 107, and a through circular slot structure is provided on one side of the mounting plate 108; a mold cavity 109 is fixedly provided in the circular slot of the mounting plate 108; and a set of cylinders are fixedly provided on both sides of the top of the mounting plate 108. The connecting rod 115 has a rectangular structure, and springs are sleeved on the outer sides of both ends of the connecting rod 115. A set of rectangular cleaning blocks 116 are slidably arranged on both sides between the two sets of connecting rods 115. The middle of the two sets of cleaning blocks 116 corresponds to the position of the blade 110, and the bottom of the cleaning blocks 116 has a beveled structure. During the rotation of the blade 110, it can rotate between the two sets of cleaning blocks 116, thereby cleaning the surface of the blade 110 through the two sets of cleaning blocks 116, avoiding the phenomenon of adhesion on the surface of the blade 110, which helps to maintain the cutting efficiency and quality of the blade 110.

[0025] The base 1 has a rectangular groove structure for feeding trough 101 fixedly installed on the top rear side; a set of stirring rollers 102 are rotatably installed on both sides inside the feeding trough 101, and a spiral structure is provided on the outer side of the stirring rollers 102; a set of first motors 103 are fixedly installed on both sides of the top of the feeding trough 101, and the first motors 103 are connected to the stirring rollers 102 in a driving connection; a cylindrical conveying trough 104 is fixedly installed on the top rear side of the base 1, and a rectangular through-slot structure is opened on the top of the conveying trough 104, which is connected to the feeding trough 101; a conveying roller 105 is rotatably installed inside the conveying trough 104, which can realize the quantitative conveying of materials; a second motor 106 is fixedly installed on one side of the top of the base 1, and the second motor 106 is connected to the conveying roller 105 in a driving connection.

[0026] The water tank 107 has a rotating blade 110 inside, and the surface of the blade 110 is in contact with the front surface of the mold cavity 109; a third motor 117 is fixedly installed inside the water tank 107, and the third motor 117 is connected to the blade 110 for transmission.

[0027] The specific usage and function of this embodiment are as follows:

[0028] Open the inlet and outlet valves of the water tank 107 in sequence to maintain the cooling water circulation and ensure that the water temperature is stable within the preset range. Start the first motor 103. After the stirring roller 102 rotates normally, slowly pour the raw material into the feeding trough 101. After the raw material is crushed and dispersed by the two sets of stirring rollers 102, it enters the conveying trough 104 through the discharge port below. Start the second motor 106, and the conveying roller 105 starts to rotate, pushing the raw material quantitatively to the die cavity 109 for extrusion. After the molten material discharged from the extruder forms a continuous strip through the discharge hole of the die cavity 109, start the third motor 117, and the blade 110 starts to rotate and cut the pellets. At this time, it is necessary to closely observe the pellets. Regarding particle shape, if the particle length is uneven, the speed of the third motor 117 can be finely adjusted. During the rotation of the blade 110, after cutting the particles, when the blade 110 rotates to contact the cleaning block 116, the blade 110 can push the two sets of cleaning blocks 116 to both sides along the connecting rod 115. At the same time, under the action of the springs on both sides of the connecting rod 115, the inner walls of the two sets of cleaning blocks 116 can remain in close contact with the surface of the blade 110, thereby effectively cleaning the material that may be stuck to the surface of the blade 110, avoiding the material sticking to the surface of the blade 110 from affecting the cutting effect and maintaining the cutting quality.

[0029] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown:

[0030] A set of cylinders 111 are fixedly installed on both sides of the interior of the water tank 107; a bottom groove 112 with a rectangular groove structure is fixedly installed on the front bottom of the water tank 107.

[0031] In this system, a set of cylindrical sliding rods 113 are slidably installed in the circular through grooves around the inner wall of the water tank 107, and the sliding rods 113 are connected to the cylinder 111 for transmission. The bottom of the four sets of sliding rods 113 is fixedly connected to a rectangular groove structure collection tank 114, and the outer wall of the collection tank 114 is in contact with the inner wall of the bottom tank 112. The outer side of the collection tank 114 is provided with a filter hole structure. The collection tank 114 can move up and down under the drive of the cylinder 111. When it descends, it sinks into the water to collect particles, and when it rises, it rises above the water surface to dehydrate.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In this invention, the cut particles fall into the collection trough 114 below. After cutting is completed, two sets of cylinders 111 can be activated to drive the slide rod 113 and the collection trough 114 to slide upward along the circular through groove on the inner wall of the water tank 107, so that the collection trough 114 is separated from the inside of the bottom tank 112 and raised, thereby lifting the material in the collection trough 114 together and dehydrating it, completing the rapid collection process, which is convenient for the collection and processing of the finished product.
