[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention can discharge materials from the upper line of the control mechanism by controlling the control mechanism. Under the wind force of the hot air blower, all materials are blown up and move toward the collection bin. During the movement, materials with larger particle sizes fall first and slide along the bottom of the inner cavity of the storage bin. Materials with appropriate particle sizes are blown by the wind to the filter plate and are blocked, and fall into the collection bin under the action of gravity. Materials with larger particle sizes cooperate with the "surrounding wind" located there to move toward the direction of the rotating fan blades, thereby screening materials of different particle sizes.

[0023] 2. The present invention cooperates with the hot air blower, storage bin, material discharge baffle and other structures. When the material is wet, its weight is greater than when it is dry. The wet material can fall faster during the wind blowing process, that is, it falls on the bottom of the inner cavity of the storage bin, and then is blown up again after moving through the rotating fan blades. Moreover, when drying, the material itself is constantly moving, which can make the surface dry more evenly.

[0024] 3. The present invention discharges the larger particle size materials into the middle of the collecting component by rotating the fan blades, and is blown up by the wind force of the hot air blower, so that the larger particle size materials are crushed by the crushing blades. The collection component rotates in opposite directions to the crushing blades, the crushing interval is shorter, and the crushing effect is better.

[0025] 4. The present invention can drive the telescopic plate and the slide seat to move up and down by rotating the second threaded shaft. When the telescopic plate moves upward, the telescopic plate itself will also extend under the pull of the discharge baffle and the filter plate. At this time, due to the increase in the distance between the collecting bin and the telescopic plate, the wind force and speed passing through the area are reduced, and the flow rate is slowed down. At this time, the particle size of the material falling into the collecting bin becomes smaller. In this way, the effect of controlling the particle size of the collected material can be achieved.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 6 As shown, the present invention provides a raw material pretreatment device for plastic material production, comprising a hot air blower 1, and further comprising:

[0035] A crushing assembly 2, which is arranged on the top of the hot air blower 1. The crushing assembly 2 includes a limiting shell 201 and a sieve plate 202. The limiting shell 201 is installed at the air outlet of the hot air blower 1, and the sieve plate 202 is installed inside the limiting shell 201;

[0036] The material handling mechanism 3 is symmetrically arranged on both sides of the crushing assembly 2. The material handling mechanism 3 includes a storage bin 301 and a movable cover plate 302. The movable cover plate 302 is hinged to the top of the storage bin 301. The storage bin 301 is connected to the limiting housing 201.

[0037] The rotating fan blade 4 is rotatably connected to the inside of the storage bin 301, one end of the rotating fan blade 4 is located inside the hot air blower 1, and the hot air blown by the hot air blower 1 can drive the rotating fan blade 4 to rotate;

[0038] Control mechanism 5, which is disposed inside the storage bin 301 and is used to control the falling of materials above the storage bin 301;

[0039] The regulating mechanism 6 is arranged inside the storage bin 301, and is used to limit the control mechanism 5, and is also used to control the pressure of the hot air generated by the hot air blower 1 discharged outside the storage bin 301;

[0040] The filter plate 7 is located inside the storage bin 301 and is hinged to the storage bin 301 at one end and hinged to the adjustment mechanism 6 at the other end. The filter plate 7 is used to block the material blown by the hot air;

[0041] A sealing mechanism 8, wherein the sealing mechanism 8 is arranged on the adjusting mechanism 6;

[0042] The collecting bin 9 is movably installed on one side of the storage bin 301 and is used to collect materials of suitable sizes.

[0043] By controlling the control mechanism 5, the materials can be discharged from the upper line of the control mechanism 5. Under the wind force of the hot air blower 1, all the materials are blown up and move toward the collecting bin 9. During the movement, the materials with larger particle sizes fall first and slide along the bottom of the inner cavity of the storage bin 301. The materials with appropriate particle sizes are blown by the wind force to the filter plate 7 and are blocked, and fall into the collecting bin 9 under the action of gravity. At the same time, a collection bag for collecting materials with smaller particle sizes can be set on the outer side of the filter plate 7.

[0044] The rotating fan blades 4 are arranged to rotate under the blowing of wind. At the same time, since the rotating fan blades 4 are arranged on the air duct, the wind can be blocked, so that the area below the line from the top of the rotating fan blades 4 to the top of the collecting bin 9 will form an "encircling wind" with smaller wind force. Materials with larger particle sizes cooperate with the "encircling wind" to move toward the direction of the rotating fan blades 4, thereby screening materials of different particle sizes.

[0045] In the process of wind blowing on the material, the material can also be dried. When the material is wet, its weight is greater than when it is dry. The wet material can fall faster during the wind blowing process, that is, it falls on the bottom of the inner cavity of the storage bin 301, and then is blown up again after moving through the rotating fan blades 4. Moreover, when drying, the material itself is constantly moving, which can make the surface dry more evenly.

[0046] like Figure 4As shown, the crushing assembly 2 also includes a driving motor 203, a crushing blade 204 and a collecting assembly 205. The driving motor 203 is fixedly installed on the top of the limiting housing 201, and the crushing blade 204 is fixedly installed on the output shaft of the driving motor 203. The crushing blade 204 drives the collecting assembly 205 to rotate around the output shaft of the driving motor 203 through the planetary gear. The sun gear of the planetary gear is fixedly connected to the bottom of the crushing blade 204, and the planetary gear of the planetary gear is rotatably connected to the surface of the screen plate 202 with its axis, and the outer gear ring of the planetary gear is fixedly connected to the collecting assembly 205.

[0047] During the rotation process, the rotating fan blades 4 discharge the materials with larger particle sizes into the interval of the collecting component 205, and continue to be blown upward under the action of the wind force of the hot air blower 1, thereby crushing the materials with larger particle sizes. Through the design of the planetary gear, the collection component 205 and the crushing blade 204 rotate in opposite directions, the crushing interval is shorter, and the crushing effect is better. At the same time, the crushed materials can be blown into the collecting bin 9 by the wind due to their smaller particle size, and the materials that do not reach the size can repeatedly fall on the bottom of the inner cavity of the storage bin 301, and are crushed again under the drive of the rotating fan blades 4, forming a continuous crushing method.

[0048] like Figure 5 As shown, the control mechanism 5 includes a first threaded shaft 501, a connecting rod 502 and a discharge baffle 503. The first threaded shaft 501 is threadedly connected to the storage bin 301. Both ends of the connecting rod 502 are hinged with connecting blocks, one of which is rotatably connected to the first threaded shaft 501, and the other is fixedly connected to the discharge baffle 503. The width of the discharge baffle 503 is the same as the width of the inner cavity of the storage bin 301.

[0049] The material discharge baffle 503 can be driven to move by rotating the first threaded shaft 501, so that the material can be discharged smoothly. The material can be injected into the storage bin 301 by flipping the movable cover plate 302, which is convenient to use.

[0050] like Figure 5 As shown, the adjustment mechanism 6 includes a telescopic plate 601, a slide seat 602 and a second threaded shaft 603. The second threaded shaft 603 is threadedly connected to the storage bin 301. The slide seat 602 is fixedly connected to the telescopic plate 601. The slide seat 602 is slidably connected to the second threaded shaft 603. The two ends of the telescopic plate 601 are hinged to the discharge baffle 503 and the filter plate 7 respectively.

[0051] By rotating the second threaded shaft 603, the telescopic plate 601 and the slide seat 602 can be driven to move up and down. When the telescopic plate 601 moves upward, the telescopic plate 601 itself will also extend under the pull of the discharge baffle 503 and the filter plate 7. At this time, due to the increase in the distance between the collecting bin 9 and the telescopic plate 601, the wind force and speed passing through the area are reduced, and the flow rate is slowed down. At this time, the particle size of the material falling into the collecting bin 9 becomes smaller. In this way, the effect of controlling the particle size of the collected material can be achieved.

[0052] like Figure 5 , Figure 6 As shown, the sealing mechanism 8 includes a fixed base 801, a sliding plate 802, a spring 803 and a roller 804. The fixed base 801 is fixedly installed on the top of the sliding seat 602. The sliding plate 802 elastically slides inside the fixed base 801 through the spring 803. The roller 804 is arranged at both ends of the top of the sliding plate 802. The sliding plate 802 has the same length as the fixed base 801.

[0053] The spring 803 is set to ensure that the sliding plate 802 is always in contact with the top of the inner cavity of the storage bin 301. A sliding groove compatible with the roller 804 is set on the top of the storage bin 301. When the telescopic plate 601 moves, the pulling of the discharge baffle 503 and the filter plate 7 at both ends will also drive the sealing mechanism 8 to move as a whole. The set roller 804 can reduce the friction of movement.

[0054] like Figure 2 , Figure 5 , Figure 6 As shown, the telescopic plate 601, the sliding seat 602 and the discharge baffle 503 have the same width, and the inner cavity of the storage bin 301 is divided into two parts by the discharge baffle 503, the telescopic plate 601, the filter plate 7, the fixed base 801 and the sliding plate 802. The cavity formed by the storage bin 301, the discharge baffle 503, the fixed base 801 and the sliding plate 802 is used to hold materials, and the area below the discharge baffle 503, the telescopic plate 601 and the filter plate 7 is used to screen the materials.

[0055] Through the coordination of structures such as the storage bin 301, the discharge baffle 503, the telescopic plate 601, the filter plate 7, the fixed base 801 and the sliding plate 802, the inner cavity of the storage bin 301 is divided into several parts that can produce different effects, and the movement of the discharge baffle 503, the telescopic plate 601 and the filter plate 7 can also control the particle size value of the collected material.

[0056] The working principle and use process of the present invention:

[0057] When in use, first rotate the second threaded shaft 603 to control the telescopic plate 601 to be in a suitable position, that is, determine the appropriate material particle size value, then open the movable cover 302 to inject material into the storage bin 301, and close the movable cover 302 after injection. Then, start the hot air blower 1 and the drive motor 203, the drive motor 203 drives the crushing blade 204 to rotate, and the crushing blade 204 drives the collecting assembly 205 to rotate in the opposite direction through the planetary gear. At this time, the rotating fan blade 4 is also driven by the hot air generated by the hot air blower 1 to rotate, and then rotates The first threaded shaft 501 drives the connecting rod 502 to move downward, and at this time, a gap is formed between the end of the material discharge baffle 503 close to the connecting rod 502 and the storage bin 301, and the material falls down. The fallen material is blown by the hot air generated by the hot air blower 1 and moves along the air duct toward the collecting bin 9. The material with a larger particle size falls down first and slides along the bottom of the inner cavity of the storage bin 301. The material with a suitable particle size is blown by the wind to the filter plate 7 and is blocked, and falls into the collecting bin 9 under the action of gravity. In the process of the material being blown by the wind, the material itself is also dried;

[0058] The larger particle size materials sliding along the bottom of the inner cavity of the storage bin 301 cooperate with the "surrounding wind" located there to move toward the direction of the rotating fan blade 4, and are discharged into the spacing of the collection component 205 under the rotation of the rotating fan blade 4. At this time, the larger particle size materials are blown upward again by the hot air, and are broken by the crushing blade 204 during the blowing process. The materials broken into suitable particle sizes enter the collection bin 9 under the action of wind.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
