Description

Technical Field

[0001] This utility model relates to the field of plastic pelletizer technology, specifically a multi-stage plastic pelletizer. Background Technology

[0002] Plastic pellets are a widely used raw material. There are many types and methods of plastic pellet production and processing. One method is to first process plastic strips and then cut the plastic strips into pellets using a plastic pelletizer.

[0003] However, existing multi-stage plastic pelletizers have the following drawbacks during use: Since multi-stage pelletizers can pelletize multiple plastic strips simultaneously, multiple plastic strips need to be fed into the pelletizer at the same time. However, when feeding multiple plastic strips, existing multi-stage pelletizers are prone to slippage of the feeding rollers, resulting in asynchronous feeding of multiple plastic strips and easy misalignment of multiple plastic strips during feeding. This requires manual adjustment, which is troublesome, time-consuming, and labor-intensive. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is: a multi-stage plastic pelletizing machine, comprising: a main body and a feeding mechanism. The main body includes a machine body, a guide seat fixed to the top of the machine body by threads, a fixed blade fixed to one side of the machine body, a cutting component installed on the machine body, an inclined plate fixed to the inner wall of the machine body, and a cover plate hinged to the machine body.

[0006] The feeding mechanism includes a frame fixed on the inner side of the cover plate, a plurality of transmission wheels arranged in an array and rotatably mounted on both sides of the frame, a rubber belt sleeved on the outer side of the relative transmission belt, a clamping member mounted on the bottom end of the frame and close to the inner side of the transmission belt, and a second motor fixed on the outer side of the cover plate.

[0007] The frame includes a central frame fixed to the inner wall of the cover plate, a plurality of ear plates fixed in an array on both sides of the central frame, and a rotating shaft that rotates through the plurality of ear plates. The transmission wheel is fixedly sleeved on the rotating shaft, and the shaft of the second motor is fixedly connected to one end of the rotating shaft.

[0008] In a preferred embodiment, the present invention can be further configured such that the top of the guide seat has grooves arranged in an array, and the positions of the grooves correspond to the positions of the rubber belt.

[0009] In a preferred embodiment, the present invention can be further configured such that the cutting component includes a hob rotatably mounted on the machine body and a first motor fixed to one side of the machine body with its shaft fixedly connected to the end of the hob.

[0010] In a preferred embodiment, the present invention can be further configured such that the clamping member includes two circular rods that move through the central frame, a U-shaped frame fixed to the bottom of the circular rods, a spring sleeved on the outside of the circular rods, and a plurality of rubber rollers rotatably mounted on the inside of the U-shaped frame.

[0011] In a preferred embodiment, the present invention can be further configured such that one end of the spring is fixed to the top of the U-shaped frame, and the other end is fixed to the bottom of the central frame.

[0012] In a preferred embodiment, the present invention can be further configured such that the surface of the rubber strip is provided with anti-slip texture.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, a machine body is provided, and a guide seat is fixed to the machine body by bolts. The top of the guide seat has multiple grooves arranged in an array, each groove is used to guide a single plastic strip, thereby effectively avoiding the situation where multiple plastic strips intersect. At the same time, a cover plate is hinged to the machine body, and a frame is fixed on the inner wall of the cover plate. Multiple transmission wheels are arranged in an array on both sides of the frame, and rubber belts are sleeved on the opposite transmission wheels. A second motor is fixed on the outer side of the cover plate and connected to one side of the transmission wheel. With the above configuration, when multiple plastic strips are fed through the grooves, the second motor starts and drives the transmission wheels to rotate. The rotation of the transmission wheels drives the rubber belt to rotate. Since the rubber belt is close to the plastic strip, it can increase the contact area with the plastic strip. Therefore, the rotation of the rubber belt stably drives the plastic strip forward, which is a stable feeding process and avoids the plastic strip slipping during feeding, thus increasing the practical performance.

[0014] 2. In this utility model, a clamping component is installed at the bottom of the frame. By setting the clamping component, the rubber strip can be pressed tightly onto the surface of the plastic strip, ensuring the contact area between the rubber strip and the surface of the plastic strip. It can also be applied to plastic strips of different sizes, further increasing its practicality. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1: Combination Figure 1-6 As shown, this embodiment provides a multi-stage plastic pelletizer, including: a main body 100 and a feeding mechanism 200.

[0019] The main body 100 includes a body 110, a guide seat 120 fixed to the top of the body 110 by threads, a fixed blade 130 fixed to one side of the body 110, a cutting component 140 installed on the body 110, an inclined plate 150 fixed to the inner wall of the body 110, and a cover plate 160 hinged to the body 110.

[0020] The body 110 is used to install other components and ensure the stability of each component. The guide seat 120 is fixed to the body 110 by threads, which facilitates installation and disassembly. Multiple grooves 121 are arranged in an array on the top of the guide seat 120. The inner bottom wall of the groove 121 is set in a semi-circular arc surface for inserting a single plastic strip. Through this setting, each groove 121 is used to guide a single plastic strip, thereby effectively avoiding the situation where multiple plastic strips intersect.

[0021] The cutting component 140 is used to cut plastic strips, including a roller cutter 141 rotatably mounted on the machine body 110 and a first motor 142 fixed on one side of the machine body 110 with its shaft fixedly connected to the end of the roller cutter 141. When the first motor 142 is started, it drives the roller cutter 141 to rotate. The roller cutter 141 rotates and cooperates with the fixed blade 130 to perform pelletizing operation on the plastic strips.

[0022] A discharge hole is provided on one side of the machine body 110. An inclined plate 150 is fixed on the inner wall of the machine body 110 to discharge the cut plastic granules. A cover plate 160 is used to close the roller cutter 141 to prevent the roller cutter 141 from being exposed and causing injury to workers. A lifting ring is fixed at the top of the cover plate 160 to facilitate lifting the cover plate 160 and increase the ease of use.

[0023] The feeding mechanism 200 is used to stably feed the plastic strip into the contact part between the roller cutter 141 and the fixed cutter 130. It includes a frame 210 fixed on the inner side of the cover plate 160, a plurality of drive wheels 220 rotatably mounted in an array on both sides of the frame 210, a rubber belt 230 sleeved on the outer side of the opposite drive belt, a clamping member 240 mounted on the bottom end of the frame 210 and close to the inner side of the drive belt, and a second motor 250 fixed on the outer side of the cover plate 160.

[0024] The frame 210 includes a central frame 211 fixed to the inner wall of the cover plate 160, a plurality of ear plates 212 fixed in an array on both sides of the central frame 211, and a rotating shaft 213 that rotates through the plurality of ear plates 212. The central frame 211 is used to fix the ear plates 212, and the ear plates 212 are used to install the rotating shaft 213 to ensure the stability of the rotating shaft 213. At the same time, the transmission wheel 220 is fixedly sleeved on the rotating shaft 213 so that the rotating shaft 213 can synchronously drive the transmission wheel 220 to rotate. In addition, the shaft of the second motor 250 is fixedly connected to the end of one side of the rotating shaft 213. The second motor 250 drives the one side of the transmission wheel 220 to rotate, thereby driving the rubber belt 230 to rotate.

[0025] Each groove 121 corresponds to a rubber belt 230. When the cover plate 160 is closed, the drive wheel 220 and the rubber belt 230 extend into the groove 121 and press the plastic strip in the groove 121 tightly, which can effectively increase the contact area with the plastic strip. Therefore, when the rubber belt 230 rotates, it can stably drive the plastic strip forward. Anti-slip texture is provided on the surface of the rubber belt 230 to play an anti-slip role.

[0026] The clamping component 240 is used to ensure that the rubber band 230 can be stably pressed against the surface of the plastic strip. The clamping component 240 includes two round rods 241 that move through the central frame 211, a U-shaped frame 242 fixed to the bottom end of the round rods 241, a spring 243 sleeved on the outside of the round rods 241, and a plurality of rubber rollers 244 rotatably mounted on the inside of the U-shaped frame 242. The round rods 241 are used to fix the U-shaped frame 242 and limit the movement of the U-shaped frame 242. The U-shaped frame 242 is used to install the rubber rollers 244. One end of the spring 243 is fixed to the top end of the U-shaped frame 242, and the other end is fixed to the bottom end of the central frame 211. Under the action of the spring 243, a downward force is applied to the U-shaped frame 242 and the rubber rollers 244, thereby enabling the rubber rollers 244 to drive the rubber band 230 to press against the surface of the plastic strip, ensuring the contact area between the rubber band 230 and the surface of the plastic strip, and is applicable to plastic strips of different sizes.

[0027] The working principle and usage process of this utility model are as follows: In use, multiple plastic strips are placed into the corresponding grooves 121 in sequence, so that each groove 121 contains a single plastic strip. The cover plate 160 is closed, so that the rubber belt 230 is pressed tightly against the surface of the plastic strip and the plastic strip is pressed into the inner cavity of the groove 121. The second motor 250 is started, which drives the rotating shaft 213 on one side to rotate. The rotating shaft 213 drives the transmission wheel 220 on one side to rotate. The rotation of the transmission wheel 220 drives the rubber belt 230 to rotate. The rotation of the rubber belt 230 drives the plastic strip forward. At the same time as the plastic strip is being conveyed forward, the first motor 142 is started, which drives the roller cutter 141 to rotate. The roller cutter 141 cooperates with the fixed cutter 130 to perform pelletizing operation on the plastic strip.

[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
