Description

Technical Field

[0001] This utility model relates to the field of long glass fiber pelletizing technology, specifically a long pelletizing machine with adjustable processing length. Background Technology

[0002] A long-particle pelletizer is a type of pelletizer that is mainly used to process various plastic raw materials or other pelletizable materials into long granules, including the pelletizing of long glass fibers.

[0003] For example, patent CN222538066U discloses a pelletizer for long glass fiber production, including a pelletizing unit. A first motor drives a pulley to rotate, which in turn drives a cutting tool to cut the long glass fiber into pellets. The pelletized glass fiber falls into a screening box, where a coarse-perforated screen intercepts large particles, while a fine-perforated screen intercepts small particles. Fine impurities pass through the fine-perforated screen and fall to the bottom of the screening box for collection. During screening, a double-headed cylinder drives the coarse and fine-perforated screens to move up and down. This can accelerate screening efficiency, thereby enabling the screening and classification of long glass fiber particles. The output shaft of the second motor drives the screw to rotate, causing the screw to move the push plate to one side. The push plate then pushes the screened particles, facilitating the discharge of the screened particles. In the above case, when cutting long glass fibers, only the first motor drives the cutter to rotate and cut. However, when processing long glass fibers, it is usually necessary to cut them into different lengths or sizes. The above case can only cut long glass fibers of a fixed size, making it difficult to adjust the cutting length or size according to different production needs, thus lacking flexibility.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing long-particle pelletizer with adjustable processing length. Utility Model Content

[0005] The purpose of this utility model is to provide a long glass fiber pelletizer with adjustable processing length, in order to solve the problem mentioned in the background art that when cutting long glass fibers, the first motor drives the cutter to rotate and cut, but when processing long glass fibers, it is usually necessary to cut the long glass fibers into different lengths or sizes. However, the above-mentioned cases can only cut long glass fibers of fixed size, and it is difficult to adjust the pellet length or size according to different production needs, thus lacking flexibility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a long-particle pelletizer with adjustable processing length, comprising a machine body, an adjustment box installed on one side of the machine body, a drive motor installed on one side of the adjustment box, and a feeding port opened on one side of the machine body; a transmission shaft is installed at the output end of the drive motor, a first gear is installed on the outer wall of the transmission shaft, a roller cutter is installed inside the machine body via a rotating column, a conveying roller is installed on the outer wall of the transmission shaft, and a pressure roller is fixedly connected inside the machine body; an adjustment mechanism for adjusting the pellet length is provided inside the adjustment box.

[0007] Furthermore, the adjusting mechanism includes a threaded rod, the outer wall of which is threadedly connected to the adjusting box. One end of the threaded rod is rotatably connected to a quadrangular prism, and the end of the quadrangular prism is slidably connected to the interior of a rotating column inside the hobbing cutter. The outer wall of the quadrangular prism is fixedly connected to a second gear and a second gear, both of which mesh with the first gear.

[0008] Furthermore, the machine body is equipped with a screening mechanism for multi-stage screening of materials. The screening mechanism includes a first screening plate and a second screening plate. Both the first screening plate and the second screening plate are movably connected to the inside of the machine body. Springs are installed around the bottom of the first screening plate and the second screening plate, and a fixing plate is installed at the bottom of the springs.

[0009] Furthermore, a first connecting rod is rotatably connected to one end of the fixed plate below the first screening plate. One end of the first connecting rod is rotatably connected to the inside of the machine body. Second connecting rods are rotatably connected to both sides of one end of the first screening plate. A rotating shaft is rotatably connected inside the machine body. An eccentric wheel is installed at one end of the rotating shaft near the first connecting rod. One end of the second connecting rod is rotatably connected to the eccentric column of the eccentric wheel.

[0010] Furthermore, a cam is installed on the outer wall of the rotating shaft, one end of which movably abuts against the bottom of the first screening plate and the top of the second screening plate. One end of the rotating shaft and the transmission shaft are both fixedly connected to a synchronous pulley, and a synchronous belt is provided between the two synchronous pulleys.

[0011] Furthermore, a fan is installed inside the machine body, and the suction end of the fan is connected to a suction pipe. A suction port is installed at the end of the suction pipe and is located above the side of the first screening plate and the second screening plate. A pull-out drawer is provided at the bottom of the machine body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This adjustable-length long-particle pelletizer uses a drive motor to rotate a transmission shaft. The first gear on the transmission shaft meshes with the second and third gears, which have different tooth pitches and numbers, thereby driving the roller cutter to rotate. By switching between different gear meshing, the rotation speed of the roller cutter can be changed, thus achieving flexible adjustment of the pellet length. When the roller cutter rotates faster, the cut particles are shorter, and when the rotation speed is slower, the cut particles are longer. It can be precisely adjusted according to actual production needs, improving the applicability of the equipment.

[0014] Furthermore, when the drive shaft rotates, it drives the rotating shaft to rotate through the synchronous pulley and synchronous belt. The eccentric wheel and cam on the rotating shaft rotate. The eccentric wheel causes the first screening plate to swing, and the cam causes the first screening plate and the second screening plate to vibrate up and down. The cut particles fall onto the screening plate, and the vibration screens particles of different sizes. Small particles fall into the pull-out drawer, and particles of different sizes are discharged from the machine body, achieving efficient and precise screening.

[0015] Furthermore, after the raw materials are cut, the blower is turned on to suck away the dust above and to the sides of the first and second screening plates through the suction pipe and suction port. This design effectively maintains a clean working environment, reduces the impact of dust on the health of operators, and prevents dust from damaging the equipment, thus extending its service life.

[0024] 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.

[0025] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The present invention provides the following technical solution: a long-particle pelletizer with adjustable processing length, comprising a machine body 1, an adjustment box 2 installed on one side of the machine body 1, a drive motor 3 installed on one side of the adjustment box 2, and a feeding port 4 opened on one side of the machine body 1; a transmission shaft 8 is installed at the output end of the drive motor 3, a first gear 9 is installed on the outer wall of the transmission shaft 8, a roller cutter 23 is installed inside the machine body 1 via a rotating column, a conveying roller 10 is installed on the outer wall of the transmission shaft 8, and a pressure roller 14 is fixedly connected inside the machine body 1; an adjustment mechanism for adjusting the pellet length is provided inside the adjustment box 2; the adjustment mechanism includes a threaded rod 13, the outer wall of the threaded rod 13 is threadedly connected to the adjustment box 2, one end of the threaded rod 13 is rotatably connected to a quadrangular prism 26, the end of the quadrangular prism 26 is slidably connected to the interior of the rotating column inside the roller cutter 23, and a second gear 11 and a third gear 12 are fixedly connected to the outer wall of the quadrangular prism 26 respectively, both the second gear 11 and the third gear 12 meshing with the first gear 9;

[0026] During use, the material enters from the feed port 4 on one side of the machine body 1, such as... Figure 1 and Figure 2 As shown, the drive motor 3 is then started, and its output shaft 8 rotates, as shown. Figure 3 and Figure 4 As shown, the conveying roller 10 on the outer wall of the drive shaft 8 conveys the material between the roller cutter 23 and the pressure roller 14, thereby facilitating the roller cutter 23 to granulate the material. Figure 4 and Figure 5 As shown, the drive motor 3 drives the transmission shaft 8 to rotate, and the first gear 9 on the outer wall of the transmission shaft 8 rotates accordingly, as... Figure 5 As shown, since the first gear 9 meshes with the second gear 11 and the third gear 12, which are fixedly connected to the outer wall of the threaded rod 13 inside the adjusting box 2, and the end of the threaded rod 13 is slidably connected to the inside of the rotating column inside the hobbing cutter 23, and the outer wall of the threaded rod 13 is threadedly connected to the adjusting box 2, the rotation of the first gear 9 will drive the second gear 11 or the third gear 12 to mesh, causing the first gear 9 to drive the second gear 11 or the third gear 12 to rotate, thereby driving the quadrangular prism 26 to rotate. Figure 6 As shown, the quadrangular prism 26 is slidably connected to the rotating column inside the hobbing cutter 23. Therefore, when the quadrangular prism 26 rotates, it will drive the hobbing cutter 23 to rotate synchronously. By setting the second gear 11 and the third gear 12 to different tooth pitches and numbers of teeth, the rotation speed of the hobbing cutter 23 can be changed by switching the second gear 11 or the third gear 12 to mesh with the first gear 9. When the rotation speed of the hobbing cutter 23 is different, the length of the cut particles will be different when the material is conveyed by the conveying roller 10 to the space between the hobbing cutter 23 and the pressure roller 14 for pelletizing. When the rotation speed of the hobbing cutter 23 is faster, the number of cuts in the same time is increased, and the length of the cut material particles is shorter. When the rotation speed of the hobbing cutter 23 is slower, the length of the cut material particles is longer. The length of the cut particles can be flexibly adjusted according to the actual production needs.

[0027] Example 2: Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 Based on Embodiment 1, a screening mechanism is also disclosed, the specific structure of which is as follows:

[0028] The screening mechanism includes a first screening plate 6 and a second screening plate 7, both of which are movably connected to the inside of the machine body 1. Springs 17 are installed around the bottom of the first screening plate 6 and the second screening plate 7, and a fixing plate 16 is installed at the bottom of the springs 17. A first connecting rod 21 is rotatably connected to one end of the fixing plate 16 below the first screening plate 6. One end of the first connecting rod 21 is rotatably connected to the inside of the machine body 1. Second connecting rods 22 are rotatably connected to both sides of one end of the first screening plate 6. A rotating shaft 18 is rotatably connected inside the machine body 1, and an eccentric wheel 2 is installed at the end of the rotating shaft 18 near the first connecting rod 21. 0. One end of the second connecting rod 22 is rotatably connected to the eccentric column of the eccentric wheel 20; a cam 19 is installed on the outer wall of the rotating shaft 18, and one end of the cam 19 movably abuts against the bottom of the first screening plate 6 and the top of the second screening plate 7. One end of the rotating shaft 18 and the transmission shaft 8 are both fixedly connected to a synchronous wheel 15, and a synchronous belt is provided between the two synchronous wheels 15; a fan 24 is installed inside the machine body 1, and the suction end of the fan 24 is connected to a suction pipe 25. A suction port is installed at the end of the suction pipe 25, and the suction port is located above the side of the first screening plate 6 and the second screening plate 7. A pull-out drawer 5 is provided at the bottom of the machine body 1.

[0029] When the drive shaft 8 rotates, the synchronous pulley 15 fixedly connected to one end of it drives the synchronous pulley 15 at one end of the rotating shaft 18 to rotate via the synchronous belt, thereby causing the rotating shaft 18 to rotate. Figure 2 and Figure 3 As shown, since an eccentric wheel 20 is installed at one end of the rotating shaft 18 near the first connecting rod 21, when the rotating shaft 18 rotates, the rotating shaft 18 will drive the eccentric wheel 20 to rotate synchronously. The eccentric column of the eccentric wheel 20 drives the second connecting rod 22, which is rotatably connected to it, to move. The movement of the second connecting rod 22 causes one end of the first screening plate 6 to swing. When the first screening plate 6 swings, it will drive the first connecting rod 21 to rotate synchronously on the machine body 1. Figure 4 and Figure 6 As shown, since a cam 19 is mounted on the outer wall of the rotating shaft 18, when the rotating shaft 18 rotates under the drive of the transmission shaft 8, the cam 19 will rotate with the rotating shaft 18, as shown. Figure 4 and Figure 6 As shown, since one end of the cam 19 moves to abut against the bottom of the first screening plate 6 and the top of the second screening plate 7, the rotation of the cam 19 causes the first screening plate 6 and the second screening plate 7 to vibrate up and down. Subsequently, the cut particles fall onto the first screening plate 6 and the second screening plate 7, as... Figure 4 and Figure 6As shown, the vibration of the first screening plate 6 and the second screening plate 7 screens particles of different sizes. Smaller particles fall into the drawer 5 at the bottom of the machine body 1 through the screening plate, while particles of different sizes are discharged from the machine body 1 through the screening plate. After the raw material is cut, the fan 24 installed inside the machine body 1 is started, and the dust above the sides of the first screening plate 6 and the second screening plate 7 is sucked away through the suction pipe 25 and the suction port to keep the working environment clean.
