Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a plastic particle uniform plasticizing extrusion device. Background Technology

[0002] In the plastics processing industry, the uniform plasticization and extrusion of plastic particles is a key factor in determining the quality and performance of plastic products. If the plastic particles are not uniformly plasticized during the extrusion process, it will lead to problems such as surface defects and internal structural defects in plastic products, which will seriously affect the performance of the products and production efficiency. The prerequisite for achieving uniform plasticization and extrusion is to ensure that the plastic particles can enter the extruder stably and uniformly.

[0003] Existing plastic particle extrusion equipment has many problems in the feeding process. Plastic particles are prone to clumping in the barrel, which leads to poor feeding or even blockage. This can cause unstable feeding speed, resulting in sometimes too many and sometimes too few plastic particles entering the extruder. This unstable feeding will cause uneven filling of plastic particles in the extruder, making it impossible to achieve uniform plasticizing and extrusion. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a plastic particle uniform plasticizing extrusion device, which can solve the problem that plastic particles are prone to agglomeration in the barrel, resulting in poor material feeding or even blockage, and thus the feeding speed is prone to be unstable. This causes the amount of plastic particles entering the extruder to be sometimes too much and sometimes too little. This unstable feeding will cause the problem of uneven filling of plastic particles in the extruder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic particle uniform plasticizing extrusion device, comprising a base, a plastic extruder body fixedly installed at the top of the base, a feeding cylinder fixedly installed at the top of the plastic extruder body, a support plate fixedly connected to the top of the feeding cylinder, a second motor fixedly installed at the top of the support plate, the output end of the second motor rotating through the lower part of the support plate and fixedly connected to a rotating column, an installation groove opened at the bottom of the rotating column, a feeding port opened at the bottom of the feeding cylinder, a feeding valve plate rotatably installed inside the feeding port, an anti-blocking feeding component provided above the feeding valve plate, the anti-blocking feeding component including a cross stirring rod, an installation block fixedly connected to the top of the cross stirring rod, and the outer surface of the installation block slidingly connected to the inner wall of the installation groove.

[0006] Preferably, a scraper is fixedly connected to one side of the cross-shaped stirring rod, and the scraper slides in contact with the inner wall of the feeding cylinder.

[0007] Preferably, a threaded groove is provided on one side of the rotating column, and a fixing bolt is threadedly connected inside the threaded groove.

[0008] Preferably, a fixing groove is provided on one side of the mounting block, and the interior of the fixing groove is slidably adapted to one end of the fixing bolt.

[0009] Preferably, four stirring rods are fixedly connected to the outer surface of the rotating column, and all four stirring rods are located above the cross stirring rod.

[0010] Preferably, a first motor is fixedly connected to one side of the feeding cylinder, and the output end of the first motor rotates through the inside of the feeding port and is fixedly connected to one side of the feeding valve plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This plastic particle uniform plasticizing extrusion equipment uses a cross-shaped stirring bar to further stir and disperse the plastic particles that are about to fall into the feed port, thereby ensuring the flowability of the plastic particles. This prevents the plastic particles from easily clogging when passing through the feed port, thus stabilizing the feeding speed of the plastic particles and making the filling amount of plastic particles in the extruder uniform. This allows the extrusion equipment to plasticize and extrude evenly, further improving the practicality of the extrusion equipment. Attached Figure Description

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a plastic particle uniform plasticizing extrusion device, including a base 1, a plastic extruder body 2 fixedly installed at the top of the base 1, a feeding cylinder 3 fixedly installed at the top of the plastic extruder body 2, a support plate 5 fixedly connected to the top of the feeding cylinder 3, a second motor 6 fixedly installed at the top of the support plate 5, the output end of the second motor 6 rotatably passes through the bottom of the support plate 5 and is fixedly connected to a rotating column 7, an installation groove 16 is opened at the bottom of the rotating column 7, a feeding port 17 is opened at the bottom of the feeding cylinder 3, a feeding valve plate 11 is rotatably installed inside the feeding port 17, an anti-blocking feeding component is provided above the feeding valve plate 11, the anti-blocking feeding component includes a cross stirring rod 9, an installation block 14 is fixedly connected to the top of the cross stirring rod 9, and the outer surface of the installation block 14 is slidably connected to the inner wall of the installation groove 16.

[0025] Furthermore, a scraper 10 is fixedly connected to one side of the cross-shaped stirring rod 9, and the scraper 10 slides in contact with the inner wall of the feeding cylinder 3.

[0026] Furthermore, a threaded groove 12 is provided on one side of the rotating column 7, and a fixing bolt 13 is connected to the internal thread of the threaded groove 12.

[0027] Furthermore, a fixing groove 15 is provided on one side of the mounting block 14, and the interior of the fixing groove 15 is slidably adapted to one end of the fixing bolt 13.

[0028] Furthermore, four stirring rods 8 are fixedly connected to the outer surface of the rotating column 7, and all four stirring rods 8 are located above the cross stirring rod 9.

[0029] Furthermore, a first motor 4 is fixedly connected to one side of the feeding cylinder 3. The output end of the first motor 4 rotates through the inside of the feeding port 17 and is fixedly connected to one side of the feeding valve plate 11.

[0030] Furthermore, firstly, plastic particles are placed into the feeding cylinder 3, and the first motor 4 is started. The output end of the first motor 4 drives the feeding valve plate 11 to rotate, opening the feeding port 17, and the plastic particles begin to fall. At this time, the second motor 6 is started, and the output end of the second motor 6 drives the rotating column 7 to rotate. The four stirring rods 8 fixedly connected to the outer surface of the rotating column 7 rotate accordingly, performing preliminary stirring on the plastic particles in the upper part of the feeding cylinder 3, so that the plastic particles are initially dispersed before entering the lower area, avoiding clumping.

[0031] Furthermore, as the rotating column 7 rotates, the cross-shaped stirring rod 9 at its bottom rotates synchronously. Then, the cross-shaped stirring rod 9 further stirs and disperses the plastic particles that are about to fall into the feed port 17, thereby ensuring the flowability of the plastic particles. This prevents the plastic particles from easily getting blocked when passing through the feed port 17, thus stabilizing the feeding speed of the plastic particles and making the filling amount of plastic particles in the extruder uniform. This allows the extrusion equipment to plasticize and extrude uniformly, further improving the practicality of the extrusion equipment.

[0032] Furthermore, the scraper 10, which is fixedly connected to one side of the cross-shaped stirring rod 9, slides in contact with the inner wall of the feeding cylinder 3. During the stirring process, the scraper 10 can promptly clean the plastic particles attached to the inner wall of the feeding cylinder 3, preventing the plastic particles from accumulating and clumping, which would affect the smoothness and uniformity of the feeding, thereby ensuring the continuity and stability of the feeding.

[0033] Furthermore, when it is necessary to disassemble, maintain or replace the cross-shaped stirring rod 9, the fixing bolt 13 is turned so that it is unscrewed from the threaded groove 12 on one side of the rotating column 7 and disengaged from the fixing groove 15 on the side of the mounting block 14. At this time, the mounting block 14 can be removed from the mounting groove 16, so as to conveniently and quickly disassemble the cross-shaped stirring rod 9.

[0034] Furthermore, the plastic particles are uniformly and smoothly fed into the plastic extruder body 2 through the feed port 17. Inside the plastic extruder body 2, the plastic particles are fully plasticized and uniformly mixed by the action of heating, pressure generated by screw rotation, and shearing force. Finally, they are continuously passed through the die in a flowing state to form the required shape and be extruded.

[0035] Structural Description:

[0036] Base 1: Used to support the entire device, providing a stable foundation and ensuring smooth operation.

[0037] Plastic extruder body 2: This is the core component for plasticizing and extruding plastic particles. Through heating, pressure and shearing force generated by screw rotation, etc., the plastic particles are fully plasticized and uniformly mixed, and finally continuously flow through the die in a flowing state to form the required shape and be extruded.

[0038] Feeding cylinder 3: Used to store plastic particles and allow them to enter the plastic extruder body smoothly. Its internal space is used to accommodate plastic particles and provide a channel for feeding plastic particles.

[0039] First motor 4: The output end is connected to the feeding valve plate. By driving the feeding valve plate to rotate, it controls the opening and closing of the feeding port, thereby controlling the falling of plastic particles and realizing the adjustment of the feeding speed.

[0040] Support plate 5: Installed above the body of the plastic extruder, it is used to fix the second motor, provide installation support for the second motor, and ensure the stability of the second motor during operation.

[0041] The second motor 6 drives the rotating column to rotate, causing the stirring rod on the rotating column to stir the plastic particles in the feeding cylinder, thereby achieving the initial dispersion and stirring of the plastic particles.

[0042] Rotating column 7: By rotating, it drives the stirring rod and cross stirring rod to stir the plastic particles at different positions in the feeding cylinder, ensuring the uniformity of the plastic particles.

[0043] Stirring rod 8: Fixed on the outer surface of the rotating column, it rotates together with the rotating column to initially stir the plastic particles in the upper part of the feeding cylinder, so that the plastic particles are initially dispersed before entering the lower area to avoid clumping.

[0044] Cross-shaped stirring rod 9: Installed at the bottom of the rotating column, it further stirs and disperses the plastic particles that are about to fall into the feed port, ensuring the flowability of the plastic particles and preventing them from easily clogging when passing through the feed port.

[0045] Scraper 10: Fixed on one side of the cross-shaped stirring rod, it slides in contact with the inner wall of the feeding cylinder. During the stirring process, it cleans up the plastic particles attached to the inner wall of the feeding cylinder in a timely manner, preventing the plastic particles from accumulating and clumping, which would affect the smoothness and uniformity of feeding, and ensuring the continuity and stability of feeding.

[0046] Feed valve plate 11: Installed inside the feed port, it is driven by the first motor to control the opening and closing of the feed port, thereby controlling the falling of plastic particles.

[0047] Threaded groove 12: It is opened on one side of the rotating column and is used to cooperate with the fixing bolt to fix the mounting block and the cross stirring rod, so as to facilitate the disassembly and installation of the cross stirring rod.

[0049] Mounting block 14: Fixed to the top of the cross-shaped stirring rod, its outer surface is slidably connected to the inner wall of the mounting groove at the bottom of the rotating column, used to mount the cross-shaped stirring rod on the rotating column.

[0050] Fixed groove 15: It is opened on one side of the mounting block and slides to fit one end of the fixing bolt, and is used to fix the cross stirring rod with the fixing bolt.

[0051] Mounting slot 16: Located at the bottom of the rotating column, it is used to mount the mounting block so that the cross-shaped stirring rod can be connected to the rotating column and rotate together with the rotating column.

[0052] Feed port 17: Located at the bottom of the feed cylinder, it is the channel through which plastic particles enter the plastic extruder body. The plastic particles enter the plastic extruder body through the feed port for plasticizing and extrusion.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
