Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and in particular to a color masterbatch granulator with anti-clogging function. Background Technology

[0002] Color masterbatch is a plastic colorant made by dispersing a high proportion of pigments or additives with thermoplastic resin. The selected resin has good wetting and dispersing effects on the colorant and good compatibility with the material being colored. Color masterbatch granulators are used in the manufacturing of color masterbatch.

[0003] A search revealed, for example, a utility model with publication number CN213166292U, which discloses a color masterbatch granulator with heat recovery function. The granulator body includes a granulator main body, a feeding hopper, an extruder main unit, a heat recovery device ring-mounted on the extruder main unit, an exhaust pipe, and an extrusion die. The feeding hopper is located at one end of the extruder main unit. During the process of adding raw materials into the granulator, since the raw materials are directly added into the granulator through the feeding port, if too much material is added at once, it will cause blockage inside the feeding port, which will affect the working efficiency. Therefore, in order to solve the above defects, the inventors propose a color masterbatch granulator with anti-blocking function. Utility Model Content

[0004] The main purpose of this utility model is to provide a color masterbatch granulator with anti-clogging function, which can effectively solve the problem of excessive material feeding at one time in the existing granulator causing blockage of raw materials inside the feed inlet.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A color masterbatch granulator with anti-clogging function includes a base and a granulator body disposed on the top surface of the base. A bracket is fixedly installed on one side of the top surface of the base, and a feeding cylinder is fixedly installed on the top surface of the bracket. A feeding port is opened on one side of the outer bottom surface of the feeding cylinder, and the feeding port is located above the feeding port of the granulator body.

[0007] The feed cylinder is slidably connected to a movable rod. A push block is fixedly installed at one end of the movable rod inside the feed cylinder, and a spring is fixedly installed on one side of the push block. The movable rod passes through the inside of the spring, and the spring is fixedly connected to one side of the inner wall of the feed cylinder. A rack is fixedly installed at one end of the movable rod outside the feed cylinder. A sector gear is rotatably connected to one side of the outer surface of the bracket, and the sector gear meshes with the rack.

[0008] Preferably, a processing hopper is fixedly installed on the outer top surface of the feeding cylinder.

One end of each of the two rotating shafts extends to the outside of the processing hopper, and a drive gear is fixedly installed at the end of each rotating shaft extending to the outside of the processing hopper. The two drive gears mesh with each other. A second motor is fixedly installed on the outer surface of the processing hopper on one side of the drive gears, and the output shaft of the second motor is fixedly connected to one of the drive gears.

[0009] Preferably, a first motor is fixedly installed on one side of the sector gear in the bracket, and the output shaft of the first motor is fixedly connected to the sector gear. A slide rod is fixedly installed on one side of the rack on the outer surface of the feed cylinder, and the rack and the slide rod are slidably connected.

[0010] Preferably, a connecting block is fixedly installed on one side of the outer surface of the granulator body's cylinder, and two guide rods are fixedly installed on one side of the connecting block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model discloses a color masterbatch granulator with anti-clogging function. By setting a feeding cylinder, in actual operation, the first motor drives the sector gear to rotate. When the toothed side of the sector gear rotates to mesh with the rack, it will drive the rack to move away from the feeding cylinder, thereby driving the movable rod and push block to move. The push block squeezes the spring, and the raw material in the processing hopper will fall into the feeding cylinder. As the sector gear continues to rotate, the squeezed spring will push the push block to reset. Then the push block can push the raw material entering the feeding cylinder to move through the feeding port into the feed inlet of the granulator body, thus discharging in batches, thereby effectively avoiding the blockage of the feed inlet caused by discharging too much material at once.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This utility model discloses a color masterbatch granulator with anti-clogging function, such as Figure 1-7 As shown, the granulator includes a base 1 and a granulator body 2 located on the top surface of the base 1. The granulator body 2 is powered by an external power source. When powered on, the color masterbatch raw material is fed into the feed cylinder through the feed port of the granulator. The screw rotates and pushes the material forward. The feed cylinder is heated to melt the color masterbatch raw material. The screw thread design cuts and mixes the color masterbatch raw material to ensure uniform composition. The molten color masterbatch raw material is extruded through multiple outlets to form continuous strip-shaped material. The extruded material is then cut into granules.

[0025] A bracket 3 is fixedly installed on one side of the top surface of the base 1, and a feeding cylinder 4 is fixedly installed on the top surface of the bracket 3. A feeding port 404 is opened on one side of the outer bottom surface of the feeding cylinder 4, and the feeding port 404 is located above the feeding port of the granulator body 2.

[0026] A movable rod 401 is slidably connected inside the feeding cylinder 4, with one part of the movable rod 401 located inside the feeding cylinder 4 and the other part located outside the feeding cylinder 4. A push block 403 is fixedly installed at one end of the movable rod 401 inside the feeding cylinder 4, and a spring 402 is fixedly installed on one side of the push block 403. The movable rod 401 passes through the inside of the spring 402, and the spring 402 is fixedly connected to one side of the inner wall of the feeding cylinder 4. When the movable rod 401 moves, it will drive the push block 403 to move. When the movable rod 401 drives the push block 403 to move towards the side of the spring 402, the push block 403 will squeeze the spring 402.

[0027] A rack 405 is fixedly installed at one end of the movable rod 401 outside the feed cylinder 4. A sector gear 407 is rotatably connected to one side of the outer surface of the bracket 3, and the sector gear 407 meshes with the rack 405. A first motor 408 is fixedly installed on one side of the sector gear 407 on the bracket 3, and the output shaft of the first motor 408 is fixedly connected to the sector gear 407. The first motor 408 is powered by an external power source. When the first motor 408 is powered on, it will drive the sector gear 407 to rotate.

[0028] When the sector gear 407 rotates, its teeth mesh with the rack 405, thus pushing the rack 405 to move. The rack 405 then drives the movable rod 401 and the push block 403 to move towards the side of the spring 402, causing the push block 403 to squeeze the spring 402. The spring 402 is compressed and stores energy. However, since the sector gear 407 only has teeth on part of its circumference, when the sector gear 407 rotates beyond a certain angle, its teeth no longer mesh with the rack 405. At this time, the spring 402 releases energy, driving the rack 405 back to its original position, forming a reciprocating motion. When the rack 405 reciprocates, it drives the movable rod 401 and the push block 403 to reciprocate, thus feeding the color masterbatch raw material in batches, avoiding excessive feeding at one time and causing blockage of the feed inlet of the granulator body 2.

[0029] A slide rod 406 is fixedly installed on one side of the rack 405 on the outer surface of the feed cylinder 4, and the rack 405 is slidably connected to the slide rod 406, so that the rack 405 can move along the slide rod 406.

[0030] A processing hopper 5 is fixedly installed on the outer top surface of the feeding cylinder 4. Two rotating shafts 5021 are rotatably connected inside the processing hopper 5, and crushing rollers 5022 are fixedly installed on the outer surface of the two rotating shafts 5021. When the two rotating shafts 5021 rotate, they will drive the two crushing rollers 5022 to rotate, which can crush large-sized color masterbatch raw materials to reduce the size of the color masterbatch raw materials and avoid blockage caused by the excessive size of the color masterbatch raw materials.

[0031] When the masterbatch material comes into contact with the two rotating crushing rollers 5022, the friction between the masterbatch material and the crushing rollers 5022 will hinder the free fall of the masterbatch material, causing the speed of the masterbatch material to decrease. This avoids excessive accumulation of the masterbatch material at the connection between the feed cylinder 4 and the processing hopper 5 due to the excessive speed of the masterbatch material falling.

[0032] One end of each of the two rotating shafts 5021 extends to the outside of the processing bucket 5. A drive gear 501 is fixedly installed on the end of each of the two rotating shafts 5021 extending to the outside of the processing bucket 5. The two drive gears 501 mesh with each other. When one drive gear 501 rotates, it will drive the other drive gear 501 to rotate in the opposite direction.

[0033] A second motor 502 is fixedly installed on the outer surface of the processing bucket 5 on one side of the drive gear 501, and the output shaft of the second motor 502 is fixedly connected to one of the drive gears 501. The second motor 502 is powered by an external power source. When the second motor 502 is powered on, it will drive one of the drive gears 501 to rotate, so that the two drive gears 501 can drive the two rotating shafts 5021 and the two crushing rollers 5022 to rotate slowly to crush the color masterbatch raw material.

[0034] When the pusher block 403 is in the initial state, it will block the connection between the processing hopper 5 and the feeding cylinder 4. Then, with the reciprocating motion of the pusher block 403, the color masterbatch raw material in the processing hopper 5 will enter the feeding cylinder 4 in batches.

[0035] A connecting block 201 is fixedly installed on one side of the outer surface of the granulator body 2. Two guide rods 202 are fixedly installed on one side of the connecting block 201, and a moving plate 204 is slidably connected to the outer surface of the two guide rods 202. The moving plate 204 can move along the two guide rods 202.

[0036] The connecting block 201 is fixedly installed with an electric push rod 203 on one side of the guide rod 202, and the output shaft of the electric push rod 203 is fixedly connected to the moving plate 204. The electric push rod 203 is powered by an external power source. When the electric push rod 203 is powered on, it can push the moving plate 204 to move.

[0037] A rotating rod 205 is rotatably connected to the center of the bottom surface of the movable plate 204, and the top surface of the rotating rod 205 extends to the top surface of the movable plate 204. A switching plate 209 is fixedly installed at the bottom end of the movable plate 204, and a limiting plate 207 is fixedly installed at the top end of the movable plate 204. A fixing hole 208 is provided on one side of the top surface of the limiting plate 207, and a plurality of positioning holes 206 arranged in a ring are provided on the top surface of the movable plate 204. When the user rotates the limiting plate 207, the rotating rod 205 and the switching plate 209 will rotate. When the limiting plate 207 is rotated, the fixing hole 208 will coincide with the plurality of positioning holes 206 in sequence. The limiting plate 207 can be fixed by inserting bolts into the overlapping positioning holes 206 and limiting holes.

[0038] Multiple unblocking rods 2091 are fixedly installed on one side of the switching plate 209. The multiple unblocking rods 2091 correspond one-to-one with the multiple outlets of the granulator body 2. By inserting the unblocking rods 2091 into the outlets of the granulator body 2, the outlets of the granulator body 2 can be unblocked, so as to avoid affecting the output of the granulator body 2 due to the blockage of the outlets of the granulator body 2.

[0039] Furthermore, a third motor 2093 is fixedly installed on the other side of the switching plate 209. A protective cover 2092 is fixedly installed on the side of the switching plate 209 and the third motor 2093 is located inside the protective cover 2092. A blade 2094 is fixedly installed on the output shaft of the third motor 2093. The third motor 2093 is powered by an external power source. After the third motor 2093 is powered on, it will drive the blade 2094 to rotate, which can cut the masterbatch raw material extruded through multiple outlets into granules.

[0040] The working principle of this utility model is as follows: After the second motor 502 is powered on, it will drive one of the drive gears 501 to rotate, so that the two drive gears 501 can drive the two rotating shafts 5021 and the two crushing rollers 5022 to rotate slowly. Then, the user pours the color masterbatch raw material into the processing hopper 5. The two slowly rotating crushing rollers 5022 crush the color masterbatch raw material. Then, the first motor 408 is powered on, driving the sector gear 407 to rotate. The rotating sector gear 407, in conjunction with the spring 402, can cause the rack 405, the movable rod 401 and the push block 403 to reciprocate. This allows the color masterbatch raw material in the processing hopper 5 to enter the feeding cylinder 4 in batches. Through the continuous reciprocating motion of the push block 403, the color masterbatch raw material entering the feeding cylinder 4 will be pushed out through the feeding port 404 and fall into the feeding port of the granulator body 2, thus performing batch feeding.

[0041] The color masterbatch raw material enters the barrel through the feed port of the granulator. The screw rotates and pushes the material forward. The barrel is heated to melt the color masterbatch raw material. The screw thread design cuts and mixes the color masterbatch raw material to ensure uniform composition. The molten color masterbatch raw material is extruded through multiple outlets to form continuous strip material. After that, when the third motor 2093 is powered on, it will drive the blade 2094 to rotate and cut the extruded material into granules.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
