Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a crushing and granulating machine. Background Technology

[0002] In some plastic processing technologies, raw materials and auxiliary materials are heated and mixed, then fed into a filter extruder for processing. A granulator is then used to crush the filtered material into smaller particles for secondary processing. Existing granulators include a first crushing chamber. Plastic is poured into the first crushing chamber, where crushing rollers and crushing plates work together to tear and crush the plastic. Simultaneously, a first electric push rod pushes a pressure plate downwards, causing the pressure plate to compress the plastic's movement space, resulting in more frequent contact and crushing of the plastic with the crushing rollers. As the plastic gradually decreases in size during crushing, two second electric push rods push two crushing plates closer to the crushing rollers, reducing the distance between the two crushing plates and the crushing rollers. During crushing, plastic particles smaller than the filter plates can pass through the filter plates and openings into the outer cylinder. A motor drives the inner cylinder to rotate, causing the inner and outer cylinders to work together to crush the plastic again until it passes through the mesh and falls into the receiving box, thus achieving the desired plastic crushing process.

[0003] Existing granulators have the following problems: the size of the particles formed after crushing is inconsistent, making it difficult to control the particle size.

[0004] Based on the above situation, there is an urgent need for a crushing and granulation machine to solve the problem of difficulty in controlling particle size. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing granulators produce particles of varying sizes after crushing, making it difficult to control particle size.

[0006] The technical solution of this utility model is as follows:

[0007] A crushing and granulating machine, comprising:

[0008] A housing having a feed inlet formed thereon;

[0009] A crushing mechanism is installed inside the housing, and the crushing mechanism includes two crushing rollers;

[0010] A screen disc is detachably installed inside the housing, and the screen disc is located below the crushing mechanism;

[0011] A vibration mechanism is connected to and drives the screen disc to vibrate.

[0012] Existing granulators produce particles of varying sizes after crushing, making it difficult to control particle size. In this solution, the filtered material is fed into the inlet and falls naturally into the crushing mechanism under gravity. Two crushing rollers rotate to crush the material, and the resulting particles fall onto the screen. The vibration mechanism drives the screen to vibrate, screening out particles larger than a specified size. After removing the screen, the larger particles are poured back into the inlet for crushing, thus ensuring that the granulated particles are all smaller than the specified size, solving the problem of difficulty in controlling particle size.

[0013] Furthermore, this solution is not limited to the specific structure of the vibration mechanism. One feasible solution is that the vibration mechanism includes an intermediate rod connected to the screen plate, the intermediate rod is connected to a rotating rod, and the rotating rod is connected to a vibration motor. When this solution is adopted, the vibration motor drives the rotating rod, the intermediate rod, and the screen plate to move in sequence, which can convert the circular motion of the rotating rod into the linear reciprocating movement of the screen plate, thereby causing the screen plate to vibrate, which is more conducive to quickly screening out particles larger than the specified size.

[0014] Furthermore, to facilitate the installation and disassembly of the screen, one feasible solution is that a column is formed on the rotating rod and a mounting hole is formed on the screen to cooperate with the column. When this solution is adopted, the column is inserted into the mounting hole, or the screen is lifted to disengage the column from the mounting hole, which can facilitate the installation and disassembly of the screen.

[0015] Furthermore, in order to concentrate the particles formed after crushing onto the screen, one feasible solution is to provide a guide plate between the crushing mechanism and the screen. When this solution is adopted, the particles can be guided to the middle of the screen by the action of the guide plate.

[0016] Furthermore, in order to limit the position of the screen disc, one feasible solution is to install a guide rod inside the housing and mount the screen disc on the guide rod. When this solution is adopted, the screen disc can vibrate along the axial direction of the guide rod through the guiding action of the guide rod.

[0017] Furthermore, to facilitate the installation or removal of the screen, one feasible solution is to install a side door on the housing, with the position of the side door corresponding to the screen. When this solution is adopted, the screen can be installed or removed by lifting the side door.

[0018] Compared with existing technologies, the beneficial effects of this utility model are:

[0019] 1. The filtered material is placed into the feed inlet and falls naturally into the crushing mechanism under gravity. The two crushing rollers rotate to crush the material. The crushed particles fall onto the screen plate. The vibration mechanism drives the screen plate to vibrate to screen out particles larger than the specified size. After the screen plate is removed, the particles larger than the specified size are poured back into the feed inlet for crushing. This process ensures that the particle size formed by granulation is smaller than the specified size, thus solving the problem of difficulty in controlling particle size.

[0020] Second, since the vibration mechanism includes an intermediate rod connected to the sieve disc, the intermediate rod is connected to a rotating rod, and the rotating rod is connected to a vibration motor, the vibration motor sequentially drives the rotating rod, the intermediate rod, and the sieve disc to move, which can convert the circular motion of the rotating rod into the linear reciprocating motion of the sieve disc, thereby causing the sieve disc to vibrate, which is more conducive to quickly screening out particles larger than the specified size.

[0021] Third, since the rotating rod has a column and the screen plate has a mounting hole that mates with the column, the column can be inserted into the mounting hole, or the screen plate can be lifted to disengage the column from the mounting hole, making it convenient and quick to install or remove the screen plate.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0034] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0035] Example:

[0036] Please refer to Figure 1 and Figure 2 A crushing and granulating machine, comprising:

[0037] The housing 1 has a feed inlet 11 formed thereon;

[0038] The crushing mechanism 2 is installed inside the housing 1. The crushing mechanism 2 includes two crushing rollers 21 and a crushing motor for driving the crushing rollers 21.

[0039] Screen 3 is detachably installed inside housing 1 and is located below crushing mechanism 2;

[0040] Vibration mechanism 4 is connected to and drives the screen plate 3 to vibrate.

[0041] Existing granulators produce particles of varying sizes after crushing, making it difficult to control particle size. In this solution, the filtered material is fed into the feed inlet 11 and falls naturally into the crushing mechanism 2 under gravity. Two crushing rollers 21 rotate to crush the material, and the resulting particles fall onto the screen plate 3. The vibration mechanism 4 drives the screen plate 3 to vibrate, thus screening out particles larger than the specified size. After removing the screen plate 3, the particles larger than the specified size are poured back into the feed inlet 11 for crushing, thereby ensuring that the particle size formed by granulation is smaller than the specified size, solving the problem of difficulty in controlling particle size.

[0042] Preferably, in order to collect qualified particles screened by the sieve 3, in this embodiment, a receiving trough 6 is installed at the lower part of the shell 1 to collect qualified particles.

[0043] Reference Figure 2 and Figure 4 This solution does not limit the specific structure of the vibration mechanism 4. One feasible solution is that the vibration mechanism 4 includes an intermediate rod 41 connected to the screen plate 3, a rotating rod 42 connected to the intermediate rod 41, and a vibration motor 43 connected to the rotating rod 42. When this solution is adopted, the vibration motor 43 drives the rotating rod 42, the intermediate rod 41 and the screen plate 3 to move in sequence. This can convert the circular motion of the rotating rod 42 into the linear reciprocating motion of the screen plate 3, thereby causing the screen plate 3 to vibrate, which is more conducive to quickly screening out particles larger than the specified size.

[0044] Reference Figure 3 , Figure 4 and Figure 5 To facilitate the installation and disassembly of the screen plate 3, one feasible solution is to have a column 44 formed on the rotating rod 42 and an installation hole 31 that mates with the column 44 on the screen plate 3. When this solution is adopted, the column 44 is inserted into the installation hole 31, or the screen plate 3 is lifted so that the column 44 is disengaged from the installation hole 31, which allows for convenient and quick installation or disassembly of the screen plate 3.

[0045] Reference Figure 2 In order to concentrate the particles formed after crushing onto the screen plate 3, one feasible solution is to set a guide plate 5 between the crushing mechanism 2 and the screen plate 3. When this solution is adopted, the particles can be guided to the middle of the screen plate 3 by the action of the guide plate 5.

[0046] To limit the movement of the screen plate 3, one feasible solution is to install a guide rod 12 inside the housing 1 and mount the screen plate 3 on the guide rod 12. When this solution is adopted, the screen plate 3 can vibrate along the axial direction of the guide rod 12 through the guiding action of the guide rod 12.

[0047] Reference Figure 1 To facilitate the installation or removal of the screen plate 3, one feasible solution is to install a side door 13 on the housing 1 and the position of the side door 13 corresponds to the screen plate 3. When this solution is adopted, the side door 13 is lifted to facilitate the installation or removal of the screen plate 3.

[0048] To address the issue of difficulty in controlling particle size, this solution involves placing the filtered material into the feed inlet 11 and allowing it to fall naturally into the crushing mechanism 2 under gravity. Two crushing rollers 21 rotate to crush the material, and the resulting particles fall onto the screen plate 3. The vibration mechanism 4 drives the screen plate 3 to vibrate, thus screening out particles larger than the specified size. After removing the screen plate 3, the particles larger than the specified size are poured back into the feed inlet 11 for crushing, thereby ensuring that the particle size formed by granulation is smaller than the specified size, thus solving the problem of difficulty in controlling particle size.

[0049] To facilitate the rapid screening of particles larger than a specified size, in this solution, the vibration mechanism 4 includes an intermediate rod 41 connected to the screen plate 3, a rotating rod 42 connected to the intermediate rod 41, and a vibration motor 43 connected to the rotating rod 42. The vibration motor 43 sequentially drives the rotating rod 42, the intermediate rod 41, and the screen plate 3 to move, which can convert the circular motion of the rotating rod 42 into the linear reciprocating movement of the screen plate 3, thereby causing the screen plate 3 to vibrate, which is more conducive to the rapid screening of particles larger than a specified size.

[0050] To facilitate the installation or removal of the screen plate 3, in this design, since the rotating rod 42 has a column 44 and the screen plate 3 has a mounting hole 31 that mates with the column 44, the column 44 can be inserted into the mounting hole 31, or the screen plate 3 can be lifted to disengage the column 44 from the mounting hole 31, thus enabling the screen plate 3 to be installed or removed conveniently and quickly.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
