Technical Field
[0001] This utility model relates to the technical field of mixing devices, and in particular to a mixing device for processing plastic rice. Background Technology
[0002] Plastic rice is a common name for plastic raw materials. Most plastic raw materials are made into granules, and their color is natural and transparent without the addition of dyes, just like rice. Therefore, they are called plastic rice, and are also known as plastic granules.
[0003] In existing technologies, the production process of plastic rice requires mixing multiple raw materials. For example, a plastic rice mixing device (publication number CN214819939U) includes a mounting plate. A first mixing box is fixedly installed at the center of the top of the mounting plate. A second mixing box is connected to the center of the top of the first mixing box. A mounting frame is fixedly installed at the center of the top of the second mixing box. Second motors are fixedly installed on the top of both sides of the mounting frame. Receiving boxes are provided on both sides of the center of the mounting frame, and a third motor is fixedly installed inside the receiving boxes. This invention solves the problem that most existing plastic rice mixing devices suffer from uneven mixing, resulting in poor mixing quality, numerous defective products, and a serious impact on product quality.
[0004] Existing mixing devices have some problems when mixing plastic pellet raw materials. Because there are many types of raw materials for plastic pellets, multiple raw materials are prone to clumping at the feed inlet of the mixing device when they are added, causing the feed inlet to become blocked. Furthermore, the premature clumping of multiple raw materials will affect the subsequent mixing effect and ultimately affect the quality of the plastic pellets.
[0005] Therefore, it is necessary to invent a mixing device for processing plastic rice to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a mixing device for processing plastic rice, so as to solve the problems mentioned in the background art.
[0007] To achieve the above object, the present utility model provides the following technical solutions: A mixing device for plastic rice processing, including a mixing cylinder, a conical part is fixedly installed at the bottom end of the mixing cylinder, a feed pipe is fixedly installed at the bottom end of the conical part, a feed hopper is fixedly installed at the outer bottom end of the feed pipe, a feed groove is provided through the outer wall bottom end of the feed pipe, and the feed groove is located inside the feed hopper. A screen is fixedly installed at the notch of the feed groove. A movable plate is installed on the side of the feed hopper away from the feed groove. The movable plate is arranged in an inclined structure, and a spring is installed between the movable plate and the inner wall of the feed hopper. A plurality of crushing blocks are fixedly installed on the side of the movable plate close to the feed groove. A rotating shaft is rotatably installed inside the mixing cylinder through a bearing. A spiral guide plate is fixedly installed at the outer bottom end of the rotating shaft, and the spiral guide plate is located inside the feed pipe. A return pipe is fixedly provided at the outer wall bottom end of the conical part. The bottom end of the return pipe is fixedly installed with a connecting pipe, and the connecting pipe is fixedly installed at the top end of the feed hopper.
[0008] Preferably, a flap is rotatably installed at the inner top end of the feed hopper through a pin shaft, and the flap is located below the connecting pipe.
[0009] Preferably, a fixed frame is fixedly installed at the inner top end of the feed hopper, and the movable plate is located below the fixed frame.
[0010] Preferably, a plurality of stirring rods are installed around the outer wall top end of the rotating shaft, and a scraping plate is fixedly installed at one end of each of the plurality of stirring rods.
[0011] Preferably, the scraping plate is arranged in a "丿" shape structure. The top end of the outer wall of the scraping plate is fitted with the inner wall of the mixing cylinder, and the bottom end of the outer wall of the scraping plate is fitted with the inner wall of the conical part.
[0012] Preferably, a motor is fixedly installed at the outer wall top end of the mixing cylinder, and a transmission belt is installed between the output shaft of the motor and the top end of the rotating shaft.
[0013] Preferably, a discharge port is provided through the outer wall bottom end of the feed pipe.
[0014] The technical effects and advantages of the present utility model:
[0015] 1. This utility model features a conical section and a feed pipe at the bottom of the mixing cylinder, with a feed hopper at the bottom outer side of the feed pipe. Plastic pellets enter the mixing cylinder through the feed hopper and feed pipe. During this process, the screen inside the feed hopper can screen out clumps of raw materials to prevent them from directly entering the mixing cylinder and affecting the mixing effect. By setting a return pipe between the conical section and the feed hopper, the raw materials in the conical section can enter the feed hopper through the return pipe. When the raw materials pass through the return pipe, they are accelerated by gravity and then impact the clumps of raw materials in the feed hopper and the movable plate. The movable plate vibrates when impacted, and at this time, the movable plate crushes the clumps of raw materials through the surface crushing blocks, thereby achieving the crushing treatment of the clumps and preventing the raw materials from clumping prematurely and affecting the mixing effect.
[0016] 2. This utility model features a flap at the top of the inside of the feeding hopper. In the initial feeding stage, the flap can be flipped to the bottom of the return pipe to limit the backflow of materials and ensure feeding efficiency. In the final feeding stage and during the mixing process, the flap can be flipped to the inlet of the feeding hopper, opening the return pipe while sealing the inlet of the feeding hopper. At this time, the backflowing raw material can be used to crush the agglomerated raw material. Furthermore, when the raw material passes through the return pipe, it can achieve mixing of raw materials at different locations, thereby further improving the mixing effect of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides, for example Figure 1-4 The mixing device for processing plastic rice shown includes a mixing cylinder 1, a conical part 2 fixedly installed at the bottom end of the mixing cylinder 1, a feed pipe 3 fixedly installed at the bottom end of the conical part 2, a feed hopper 4 fixedly installed at the bottom outer side of the feed pipe 3, a feed groove 5 penetrating through the bottom end of the outer side wall of the feed pipe 3, and the feed groove 5 is located inside the feed hopper 4. A screen 6 is fixedly installed at the opening of the feed groove 5, and the screen 6 is used to screen out the agglomerated raw materials.
[0024] A movable plate 7 is installed on the side of the feed hopper 4 away from the feed trough 5. The movable plate 7 is inclined, and a spring 8 is installed between the movable plate 7 and the inner wall of the feed hopper 4. Multiple crushing blocks 9 are fixedly installed on the side of the movable plate 7 near the feed trough 5. When the crushing blocks 9 follow the vibration of the movable plate 7, they can squeeze the agglomerated raw material to break it. The power source for the vibration of the movable plate 7 is the impact kinetic energy of the backflowing raw material. Since the movable plate 7 is inclined, when the raw material falls down and impacts the movable plate 7, the movable plate 7 moves away from the feed trough 5 and compresses the spring 8. When the movable plate 7 moves to a certain extent, the movable plate 7 is misaligned with the falling raw material. At this time, the movable plate 7 loses its power source. At this time, the spring 8 releases kinetic energy to drive the movable plate 7 to reset. After resetting, the movable plate 7 is impacted by the raw material again. In the above process, the movable plate 7 achieves reciprocating motion to achieve the vibration effect.
[0025] Inside the mixing cylinder 1, a rotating shaft 10 is rotatably mounted via bearings. A spiral guide plate 11 is fixedly mounted on the bottom outer side of the rotating shaft 10, and the spiral guide plate 11 is located inside the feed pipe 3. A return pipe 12 is fixedly provided on the bottom outer wall of the conical part 2. A connecting pipe 13 is fixedly mounted on the bottom end of the return pipe 12, and the connecting pipe 13 is fixedly mounted on the top of the feed hopper 4. The return pipe 12 and the connecting pipe 13 form a return channel for raw materials, so that the raw materials in the conical part 2 can return to the feed hopper 4.
[0026] At the inner top of the feed hopper 4, a flap 14 is rotatably installed through a pin shaft. The flap 14 is located below the connecting pipe 13. The flap 14 can be flipped between below the connecting pipe 13 and the inlet of the feed hopper 4. Moreover, the flap 14 is equipped with a handle and a fixing pin. The fixing pin can be matched with two pin holes on the outer side of the feed hopper 4 to limit and lock the handle at two positions, so as to lock the position of the flap 14. The method of locking the position of the flap 14 by the handle and the pin is a conventional means in the art and will not be elaborated here;
[0027] At the inner top of the feed hopper 4, a fixed frame 15 is fixedly installed. The movable plate 7 is located below the fixed frame 15. The fixed frame 15 is used to prevent raw materials from entering between the movable plate 7 and the feed hopper 4 and causing the movable plate 7 to jam;
[0028] At the top of the outer wall of the rotating shaft 10, a plurality of stirring rods 16 are installed around. At one end of each of the plurality of stirring rods 16, a scraper 17 is fixedly installed. The scraper 17 is set in a "丿" shape structure. The top of the outer wall of the scraper 17 is fitted with the inner wall of the mixing cylinder 1, and the bottom of the outer wall of the scraper 17 is fitted with the inner wall of the conical part 2. The scraper 17 can scrape up the materials adhering to the inside of the mixing cylinder 1 and the conical part 2 to ensure the mixing effect. At the top of the outer wall of the mixing cylinder 1, a motor 18 is fixedly installed. A transmission belt is installed between the output shaft of the motor 18 and the top of the rotating shaft 10. The transmission belt includes a pulley and a belt, which can achieve the power transmission between the motor 18 and the rotating shaft 10;
[0029] At the bottom of the outer wall of the feed pipe 3, a discharge port 19 is penetrated. An activity door is arranged in the discharge port 19 to control the discharge of materials.
[0030] The working principle of the present utility model:
[0031] When the device is in use, first flip the flap 14 to below the return pipe 12. At this time, the inlet of the feed hopper 4 is opened. At this time, the plastic rice raw materials can be put into the inside of the feed hopper 4. The unclumped raw materials enter the feed trough 5 after passing through the screen 6, and then enter the feed pipe 3. At this time, start the motor 18. The motor 18 drives the rotating shaft 10 to rotate through the transmission belt. The rotating shaft 1带动螺旋导板11转动,螺旋导板11将进料管3内部底端的物料向上输送,此时塑料米原料被输送至锥形部2以及混料筒1内,此过程中,结团的原料被筛网6分隔至进料斗4内;
[0032] It should be noted that there is an unclear part in the original text of item where "转轴1带动螺旋导板11转动" seems to be an incorrect expression. It should probably be "转轴10带动螺旋导板11转动". The above translation is based on the corrected understanding.After all the plastic pellets are fed into the feed hopper 4, the flap 14 is flipped so that it rotates to the entrance of the feed hopper 4. At this time, the flap 14 can block the feed hopper 4, and it no longer blocks the channel formed by the return pipe 12 and the connecting pipe 13. At this time, the raw material in the conical part 2 passes through the return pipe 12 and the connecting pipe 13 under the action of gravity and enters the feed hopper 4. The raw material is accelerated by gravity during the process of passing through the return pipe 12 and the connecting pipe 13. When the accelerated raw material falls into the feed hopper 4... The agglomerated raw material and the movable plate 7 are impacted, and some of the agglomerated raw material is broken by the impact. At the same time, the movable plate 7 moves away from the feed trough 5 when it is impacted and compresses the spring 8. Then the spring 8 releases kinetic energy to drive the movable plate 7 to reset, so as to realize the vibration of the movable plate 7. The vibrating movable plate 7 squeezes the agglomerated raw material through the crushing blocks 9 on its surface, so as to break the agglomerated raw material. The crushed raw material passes through the screen 6 and enters the feed pipe 3, and then enters the conical part 2 to complete the mixing with the mixing cylinder 1.
[0033] After the mixing is completed, the control motor 18 rotates in reverse and opens the discharge port. At this time, the spiral guide plate 11 rotates in reverse to convey the raw materials in the mixing cylinder 1 and the conical part 2 downward. The raw materials are discharged through the feed pipe 3 and the discharge port 19.
[0034] It should be noted that the motor 18 in this embodiment is a three-phase motor that can rotate in both directions and is equipped with a controller, which can rotate in both directions according to the user's operation.
[0035] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
