Description

Technical Field

[0001] This utility model relates to the field of pelletizer technology, specifically to a front door feeding port structure for a pelletizer. Background Technology

[0002] A pelletizer is a device used to cut plastic materials into small pellets, primarily used in the plastics processing industry. The front feed port is one of the most important structures on a pelletizer. Located at the front of the pelletizer, it is the material inlet that is easily monitored and intervened by the operator. Its core function is to stably supply the raw materials to be processed into the extrusion system (such as the screw and barrel). These raw materials include plastic pellets, pigments, resins, or fillers.

[0003] The existing pellet mill's front feed inlet has a complex and poorly designed structure. Currently, it only guides the feed strips during transport using guide rollers. However, the feed strips may tilt upwards during transport, and the front feed inlet cannot effectively limit their movement, resulting in poor stability during transport. Furthermore, the existing front feed inlet lacks a limiting mechanism at the feed strip output position, allowing the feed strips to potentially veer outwards, bending towards both ends of the feed inlet and eventually detaching from the conveyor track. Therefore, the inventor has improved the structure of the pellet mill's front feed inlet. Utility Model Content

[0004] The purpose of this utility model is to provide a front feeding port structure for a pelletizer. This front feeding port structure has a simple structure and reasonable design. The upper pressure roller can limit the top of the pellet, preventing the pellet from tilting upwards during the conveying process. It limits the range of movement of the pellet during the conveying process, preventing the pellet from tilting upwards, so that the pellet can be output in an orderly manner, ensuring the stability of the conveying process. It can also prevent the pellet from slipping outwards and from deviating from the conveying track. This solves the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a front door feeding port structure for a pelletizer, comprising a conveying mechanism, a guiding mechanism and a wire guide mechanism located on one side of the guiding mechanism, and a limiting mechanism above the wire guide mechanism. The conveying mechanism includes a front door with a feeding port installed on it. The guiding mechanism includes a guide roller with multiple equally spaced guide grooves. The wire guide mechanism includes a support platform and a wire guide wheel mounted on the support platform. A fixing hole is formed on the support platform, penetrating both ends, and the wire guide wheel is fixed in the fixing hole. The limiting mechanism includes an upper pressure roller with support arms fixed at both ends. Rotating bolts are provided on both support arms, and the two support arms are connected to the front door via the rotating bolts, allowing the support arms to rotate along the rotating bolts. Limiting posts are provided at the ends of the two support arms away from the upper pressure roller, and rotating grooves are formed on the two limiting posts. The ends of the two support arms away from the upper pressure roller are slidably disposed within the rotating grooves.

[0006] Preferably, the guide roller is horizontally positioned inside the front door, and both ends of the guide roller are rotatably connected to the front door. The guide roller is driven by external equipment to allow it to rotate.

[0007] Preferably, the guide wheel and the fixing holes are provided in two sets, with the two sets of fixing holes symmetrical to both ends of the support platform, and each set of fixing holes is provided with multiple holes and distributed at equal intervals on the support platform.

[0008] Preferably, the guide wheel includes a positioning post, an inner support body, and a top cover arranged sequentially from bottom to top, with the positioning post passing through the fixing hole from top to bottom and inserted into the fixing hole.

[0009] Preferably, the inner support is fixed between the positioning column and the top cover, and the outer side of the inner support is equipped with freely rotating wheels.

[0010] Preferably, multiple equally spaced fitting grooves are formed on the upper pressure roller, and the upper pressure roller is positioned above the guide roller. The upper pressure roller and the guide roller cooperate to limit the movement range of the material strip during the conveying process, prevent the material strip from warping, and allow the material strip to be output in an orderly manner.

[0011] Preferably, the two limit posts are fixed at both ends of the front door, and both limit posts are set in an arc shape.

[0012] Preferably, positioning bolts are provided on both limit posts, and the two support arms are fixed to the front door by the positioning bolts on them. The two support arms can be flipped on the two rotating bolts respectively, and the two support arms slide in the two rotating grooves. When they slide to the designated position, the two positioning bolts limit the ends of the two support arms, thereby causing the upper pressure roller to flip to the designated height. Thus, the height of the upper pressure roller can be adjusted according to actual needs, thereby adapting to material strips of different heights and increasing the applicability of the front door feeding port structure of the pelletizer.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a front feeding port structure for a pelletizer. The front feeding port structure includes a conveying mechanism, a guiding mechanism, and a wire guide mechanism located on one side of the guiding mechanism. A limiting mechanism is provided above the wire guide mechanism. The overall structure is simple and rationally designed. The guiding mechanism includes a guide roller with multiple equally spaced guide grooves. The limiting mechanism includes an upper pressure roller with multiple equally spaced fitting grooves. The upper pressure roller is positioned above the guide roller and can limit the top of the pellet, preventing it from tilting upwards during conveying. The height of the upper pressure roller is adjustable to accommodate pellets of different heights. The upper pressure roller, in conjunction with the guide roller, limits the movement range of the pellet during conveying, preventing tilting and ensuring orderly output of the pellets. This provides stability during the conveying process and enhances practicality.

[0015] 2. The guide wire mechanism in this utility model includes a support platform and guide wire wheels set on the support platform. Fixed holes are formed on the support platform through both ends. The guide wire wheels are fixed in the fixed holes. During use, the distance between the two guide wire wheels can be adjusted according to the number of material strips, that is, the width of the material strip output position can be adjusted to prevent the material strips from going out and to avoid the material strips from leaving the conveying track. This makes the front door feeding port structure of the pelletizer more applicable and suitable for widespread use. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0025] Please see Figure 1 The present invention provides an embodiment of a front door feeding port structure for a pelletizer. The front door feeding port structure of the pelletizer includes a conveying mechanism 1, a guiding mechanism 2 and a wire guide mechanism 3 located on one side of the guiding mechanism 2, and a limiting mechanism 4 above the wire guide mechanism 3.

[0026] Please see Figure 2 The conveying mechanism 1 includes a front door 11 with a feeding port 12 installed on it. The guiding mechanism 2 includes a guide roller 21 with multiple equally spaced guide grooves 22 formed on it. The guide roller 21 is horizontally positioned inside the front door 11, and both ends of the guide roller 21 are rotatably connected to the front door 11. The guide roller 21 is driven by an external device to rotate. In this embodiment, the device is a motor, which drives the guide roller 21 to rotate, thereby causing multiple strips of material to pass through the feeding port 12 and then through the multiple guide grooves 22 for conveying. The guide roller mechanism 3 includes a support platform 31 and a guide roller 32 set on the support platform 31. The limiting mechanism 4 includes an upper pressure roller 41, which is set above the guide roller 21. The upper pressure roller 41 cooperates with the guide roller 21 to limit the movement range of the material strip during the material strip conveying process, so as to prevent the material strip from tilting and to allow the material strip to be output in an orderly manner. Multiple equally spaced fitting grooves 42 are formed on the upper pressure roller 41. Support arms 43 are fixed at both ends of the upper pressure roller 41.

[0027] Please see Figure 3 A fixing hole 33 is formed on the support platform 31, extending through both ends. The guide wheel 32 is fixed in the fixing hole 33. Both the guide wheel 32 and the fixing hole 33 are provided in two sets. The two sets of fixing holes 33 are symmetrical to both ends of the support platform 31. Each set of fixing holes 33 is provided with multiple holes and is distributed at equal intervals on the support platform 31.

[0028] Please see Figure 4Each of the two support arms 43 is equipped with a rotating bolt 44, and the two support arms 43 are respectively connected to the front door 11 through the rotating bolt 44, so that the support arms 43 can rotate along the rotating bolt 44. A limit post 45 is provided at the end of each support arm 43 away from the upper pressure roller 41. The two limit posts 45 are respectively fixed to both ends of the front door 11, and both limit posts 45 are arc-shaped. A rotating groove 46 is formed on each limit post 45. The end of each support arm 43 away from the upper pressure roller 41 is slidably disposed in the rotating groove 46. The device is equipped with positioning bolts 47, and two support arms 43 are fixed to the front door 11 by the positioning bolts 47. The two support arms 43 can be flipped on the two rotating bolts 44, and the two support arms 43 slide in the two rotating slide grooves 46. When they slide to the designated position, the two positioning bolts 47 limit the ends of the two support arms 43, thereby causing the upper pressure roller 41 to flip to the designated height. Thus, the height of the upper pressure roller 41 can be adjusted according to actual needs, thereby adapting to material strips of different heights and increasing the applicability of the front door feeding port structure of the pelletizer.

[0029] Please see Figure 5 The guide wheel 32 includes a positioning post 321, an inner support body 322, and a top cover 324 arranged sequentially from bottom to top. The positioning post 321 passes through the fixing hole 33 from top to bottom and is inserted into the fixing hole 33. The inner support body 322 is fixed between the positioning post 321 and the top cover 324, and a freely rotatable wheel 323 is installed on the outside of the inner support body 322. The wheel 323 is used to limit the conveying range of the material strip at the edge position.

[0030] Working principle: Please refer to the following again. Figures 1 to 5In the operation of this invention, multiple strips are input from the end of the feed port 12 away from the upper pressure roller 41. After passing through the feed port 12, the multiple strips enter multiple guide grooves 22 respectively. The multiple guide grooves 22 isolate the multiple strips and output them separately. The height of the upper pressure roller 41 is adjusted according to the height of the strips. During the adjustment process, the two support arms 43 rotate on the two rotating bolts 44, driving the upper pressure roller 41 to rotate to the specified height. During this process, the ends of the two support arms 43 slide in the two rotating slide grooves 46 respectively. When the upper pressure roller 41 rotates to the appropriate height... Subsequently, two positioning bolts 47 are respectively installed at the ends of the two support arms 43 to limit the upper pressure roller 41 and the two support arms 43. The material strip at the edge of the position will contact the two wheels 323, generate friction, and drive the wheels 323 to rotate. This ensures that during the conveying process, the bottom of the material strip is limited by the guide roller 21 and the top is limited by the upper pressure roller 41. Together with the guide rollers 32 at both ends of the front door 11, the output range of the material strip can be limited, so that the material strip cannot be tilted up or output in a bent state towards both ends of the front door 11, thus ensuring the stability of the material strip during the conveying process.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
