Description

Technical Field

[0001] This utility model relates to the field of pelletizer technology, specifically to a pelletizer scraper frame structure. Background Technology

[0002] A pelletizer is a mechanical device that cuts waste plastics, sponges, and other materials into pellets or blocks, and is widely used in the field of plastic recycling. The pelletizer is equipped with a scraper holder, which is a component used to compress and scrape off the material.

[0003] In existing pelletizer scraper holders, the spline rollers continuously rotate to convey material, resulting in significant swaying or vibration. In some scenarios, this can cause material to fail to be accurately delivered to the roller blades, leading to poor long-term stability. Furthermore, existing scraper holders lack a structure to limit material movement, causing material to tilt upwards during conveyance. The scraper body cannot contact the tilted portion, resulting in incomplete cutting and reduced cutting efficiency. To address this, the inventors designed a pressing scraper holder structure for pelletizers, which presses the scraper holder firmly during operation, ensuring it does not vibrate or sway excessively. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure scraper holder structure for a pelletizer. This structure is simple and rationally designed. Two ejector pins are connected to two supports respectively, pressing the supports together to ensure the spline roller remains stable during operation. This allows the material to be conveyed to the scraper body in a stable state, avoiding vibration or large-scale shaking during operation. This ensures the material is accurately delivered to the scraper body, enabling the scraper body to quickly cut the material. It also guarantees long-term stability and prevents the material from excessively tilting upwards during conveying, thus preventing situations where the material cannot be cut due to excessive tilting. This ensures cutting efficiency and solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scraper frame structure for a pelletizer, comprising a scraper frame and a scraper frame assembly disposed on one side of the scraper frame, a roller blade assembly disposed between the scraper frame and the scraper frame assembly, the scraper frame comprising a base and two supports fixed to the upper surface of the base, the two supports being arranged in parallel and symmetrically on the base, the scraper frame assembly comprising a back plate and a hydraulic rod disposed at the end of the back plate away from the base, with both ends of the hydraulic rod connected to... The lugs are connected to the back plate and the upper support platform respectively through the two lugs. The upper support platform and the back plate are connected by two flip hinges. The upper support platform is equipped with a ejector pin and a cylinder located on one side of the ejector pin. The ejector pin passes through the upper support platform from top to bottom and extends to the bottom of the upper support platform. The ejector pin is located above the bracket and contacts the upper end face of the bracket to press the bracket. The cylinder is fixed to the upper end face of the upper support platform, and the output end of the cylinder is connected to a material limiting rod. The material limiting rod is located above the roller cutter assembly.

[0006] Preferably, bearings are installed at the ends of the two supports that are far apart from each other, and a spline roller is installed between the two bearings. The spline roller is located at the end of the hobbing assembly that is far away from the back plate; the spline roller can rotate with the two bearings.

[0007] Preferably, there are two ejector pins and two cylinders, with the two ejector pins located at the ends of the two cylinders that are far apart from each other.

[0008] Preferably, the pressure scraper holder assembly also includes a baffle plate fixed to the lower end face of the upper support platform. The baffle plate is vertically arranged and located between the ejector pin and the material limiting rod. The baffle plate plays a primary limiting role for the material, and the two material limiting rods play a secondary limiting role for the material, thereby preventing the material from excessively tilting up and causing incomplete cutting.

[0009] Preferably, the roller assembly includes a rotating shaft and a scraper body mounted on the rotating shaft. Both the rotating shaft and the scraper body are horizontally arranged, and the rotating shaft is mounted on a back plate to keep the structure of the rotating shaft stable and to support the rotation of the scraper body.

[0010] Preferably, a gap is provided between the base and the back plate, and the hobbing assembly is disposed within the gap.

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

[0012] 1. This utility model provides a scraper holder structure for a pelletizer. The scraper holder structure includes a scraper holder and a scraper holder assembly disposed on one side of the scraper holder. A roller cutter assembly is disposed between the scraper holder and the scraper holder assembly. The overall structure is simple and reasonably designed. The scraper holder assembly includes a back plate and a hydraulic rod disposed at the end of the back plate away from the base. Both ends of the hydraulic rod are connected to ear plates, and the hydraulic rod is connected to the back plate and the upper support platform respectively through the two ear plates. The upper support platform is connected to the back plate through two flip hinges. A ejector pin and a cylinder located on one side of the ejector pin are disposed on the upper support platform. The ejector pin penetrates from top to bottom. The upper support platform extends to its lower part, and the ejector pins are positioned above the bracket and contact the upper end face of the bracket to press the bracket. The hydraulic rod rotates, causing the upper support platform and two ejector pins to rotate to the designated position, so that the two ejector pins contact and connect with the two brackets respectively, pressing the brackets to ensure that the spline roller remains stable during operation. This allows the material to be conveyed to the scraper body in a stable state, avoiding vibration or large shaking during operation. It ensures that the material is accurately conveyed to the scraper body, allowing the scraper body to quickly cut the material and ensuring long-term stability, making it suitable for widespread use.

[0013] 2. This utility model has two cylinders, and the output ends of both cylinders are connected to material limiting rods. The material limiting rods are located above the scraper body. The scraper frame assembly also includes a baffle plate fixed to the lower end face of the upper support platform. The baffle plate is vertically arranged and located between the ejector pin and the material limiting rods. The baffle plate plays a primary limiting role for the material. The operation of the two cylinders can drive the material limiting rods to move to a specified height, so that the two material limiting rods play a secondary limiting role for the material. This prevents the material from excessively tilting upwards during the conveying process, which could lead to incomplete cutting. It ensures cutting efficiency and practicality by preventing the material from becoming uncut due to excessive tilting. Attached Figure Description

[0021] Please see Figure 1The present invention provides an embodiment of a pelletizer's pressure scraper frame structure, which includes a scraper frame 1 and a pressure scraper frame assembly 2 disposed on one side of the scraper frame 1, with a roller blade assembly 3 disposed between the scraper frame 1 and the pressure scraper frame assembly 2.

[0022] Please see Figure 2 The scraper holder 1 includes a base 11 and two supports 12 fixed to the upper surface of the base 11. The two supports 12 are arranged in parallel and symmetrically on the base 11. The scraper holder assembly 2 includes a back plate 21 and a hydraulic rod 22 located at the end of the back plate 21 away from the base 11. Both ends of the hydraulic rod 22 are connected to ear plates 23, and the hydraulic rod 22 is connected to the back plate 21 and the upper support platform 24 respectively through the two ear plates 23. The upper support platform 24 is connected to the back plate 21 through two hinges 25. The upper support platform 24 is provided with ejector pins 26 and cylinders 27 located on one side of the ejector pins 26. There are two ejector pins 26 and two cylinders 27. The two ejector pins 26 are located at the ends of the two cylinders 27 that are far apart from each other. The two ejector pins 26 penetrate the upper support platform 24 from top to bottom and extend to the bottom of the upper support platform 24. The needles 26 are respectively positioned above the two supports 12 and are in contact with the upper surfaces of the two supports 12 to press the two supports 12 together. The two cylinders 27 are fixed to the upper surface of the upper support platform 24, and the output ends of the two cylinders 27 are connected to material limiting rods 28. The two material limiting rods 28 are positioned above the roller cutter assembly 3. In addition, the pressure scraper frame assembly 2 also includes a baffle plate 29 fixed to the lower surface of the upper support platform 24. The baffle plate 29 is vertically positioned and located between the ejector needles 26 and the material limiting rods 28. The baffle plate 29 plays a primary limiting role for the material. The operation of the two cylinders 27 can drive the two material limiting rods 28 to move to a specified height. The two material limiting rods 28 play a secondary limiting role for the material, thereby preventing the material from excessively tilting up and causing incomplete cutting.

[0023] Please see Figure 3 Bearings 13 are installed at the ends of the two supports 12 that are far apart from each other. A spline roller 14 is installed between the two bearings 13. The spline roller 14 is located at the end of the roller assembly 3 that is far away from the back plate 21. The spline roller 14 can rotate with the two bearings 13. The roller assembly 3 includes a rotating shaft 31 and a scraper body 32 mounted on the rotating shaft 31. Both the rotating shaft 31 and the scraper body 32 are horizontally arranged. The rotating shaft 31 is mounted on the back plate 21, which makes the structure of the rotating shaft 31 stable and can support the rotation of the scraper body 32. The rotating shaft 31 and the scraper body 32 need an external device to drive their rotation. This device is existing technology and will not be described in detail here. A gap is provided between the base 11 and the back plate 21, and the roller assembly 3 is located in the gap.

[0024] Working principle: Please refer to the following again. Figures 1 to 3 In the operation of this utility model, when the hydraulic rod 22 drives the upper support platform 24 to rotate to a certain angle along the hinge 25, the two ejector pins 26 respectively contact and connect with the upper end faces of the two brackets 12, ensuring that the spline roller 14 remains stable during operation, allowing the material to be conveyed to the scraper body 32 in a stable state. This prevents the gap between the scraper body 32 and the spline roller 14 from being too large, causing the material strip to get caught between the scraper body 32 and the spline roller 14 and resulting in jamming. The ejector pins 26 can be adjusted up and down according to the wear condition of the spline roller 14, ensuring that the spline roller 14 frame will not rise and affect stability, avoiding vibration or large-scale shaking during operation, allowing the material to be accurately conveyed to the scraper body 32, enabling the scraper body 32 to quickly cut the material, and ensuring long-term stability.
