Abstract
Description
Technical Field
[0001] This utility model relates to the field of pelletizing device technology, specifically to a blade adjustment structure for a masterbatch processing pelletizing device. Background Technology
[0002] Masterbatch is a widely used raw material in plastic processing. The full name of masterbatch is plastic masterbatch. It is a plastic colorant or additive concentrate made by dispersing a high proportion of pigments or additives with thermoplastic resin. Masterbatch processing and pelletizing is an important step in the production process. According to the pelletizing process, there are hot-cut pellets and cold-cut pellets. Cold-cut pellets are made by first cooling and solidifying the extruded strip material through air cooling or water cooling, and then cutting it into pellets with a cutter.
[0003] CN210173964U discloses an adjusting device for a masterbatch pelletizer, including a support plate. The four bottom corners of the support plate are supported by support legs. Support columns are vertically connected to both sides of the top of the support plate. A top plate is horizontally connected to the top of the two support columns, and sliding sleeves are slidably fitted onto both support columns. A blade is horizontally connected between the two sliding sleeves, and a driving mechanism is provided at the top of the blade. This invention, by setting a driving mechanism, can drive the blade to move up and down, causing the blade to pelletize the masterbatch material. A limiting mechanism can limit the size of the masterbatch material to be cut, ensuring that the cut masterbatch pellets are of uniform size. A positioning mechanism can adjust the limiting mechanism, thereby facilitating the blade to cut the masterbatch material into masterbatch pellets of different sizes, effectively improving the applicability of this device.
[0004] While existing technology CN210173964U offers many advantages during use, it still suffers from the following problems: its protection of the cutter is not adequate. During the hot melt extrusion process, uneven cooling can cause bumps or pits to appear on the surface of the material column. As a result, when the blade cuts multiple material columns as a whole, uneven local stress can occur, leading to more severe local wear of the blade and affecting its service life. Utility Model Content
[0005] To address the problems in the prior art, this utility model provides a blade adjustment structure for a masterbatch processing pelletizing device.
[0006] The technical solution adopted by this utility model to solve its technical problem is a blade adjustment structure for a masterbatch processing pelletizing device, including a processing table, a baffle plate, and a frame. A material support plate is screwed to the upper outer wall of the processing table. A discharge port is opened on the outer wall of the processing table away from the material support plate. A baffle plate is screwed to the upper outer wall of the material support plate. A frame is screwed to the upper outer wall of the processing table. A support plate is set inside the frame. A sliding groove is equally spaced and parallel on the outer wall of the support plate. A slider is slidably installed inside the sliding groove. A cutter is installed on the lower outer wall of the slider. Fixing blocks are installed on both sides of the upper outer wall of the baffle plate. A movable rod is movably installed inside the fixing block. A connecting plate is screwed to the outer wall of one end of the movable rod. A grinding block is installed on the outer wall of the connecting plate.
[0007] By adopting the above technical solution, the support plate can support the material column to be cut, and the cut masterbatch can be discharged centrally through the discharge port, which facilitates the subsequent collection of masterbatch by the staff through the collection box and discharge port. The cutter can move vertically with the support plate, and the slider and slide can provide a buffer distance for the cutter. The first spring can buffer and automatically adjust the cutter, avoiding excessive wear of the blade due to uneven local force, improving the stress condition of the blade, and extending its service life. During the vertical movement of the cutter, the cutter surface contacts the outer wall of the grinding block, which can grind the outer wall of the cutter during the cutting process, ensuring the sharpness of the cutter, extending the service life of the cutter, and ensuring the quality of the cut particles.
[0008] Specifically, a baffle is screwed to one side of the outer wall of the upper end of the processing table. The inner wall size of the baffle is larger than the size of the unloading port, and the baffle is located on the outer side of the upper end of the unloading port.
[0009] By adopting the above technical solution, the baffle can effectively prevent the cut masterbatch from scattering in all directions during the unloading process, ensure that the masterbatch is collected smoothly at the unloading port, keep the working environment clean, and reduce material waste.
[0010] Specifically, the lower outer wall of the baffle plate and the upper outer wall of the support plate are provided with equally spaced parallel material feeding holes, which are designed in an arc shape.
[0011] By adopting the above technical solution, the supporting pusher device can push and move the material column inside the feed hole, driving the masterbatch to move towards the cutter position on the support plate. The baffle plate, together with the support plate, can limit the material column, preventing it from tilting up during the cutting process, ensuring the cutting quality of the material column. The arc shape facilitates material movement, ensuring the continuity and efficiency of the pelletizing process.
[0012] Specifically, the frame is located outside the baffle plate, and hydraulic cylinders are screwed to the outer walls on both sides of the frame. The lower outer wall of the hydraulic cylinder is connected to the upper outer wall of the support plate.
[0013] By adopting the above technical solution, the hydraulic cylinder is controlled by the matching hydraulic control device, thereby driving the support plate to move vertically. The working height of the support plate and the cutter can be adjusted to ensure the pelletizing requirements of the masterbatch.
[0014] Specifically, a first spring is provided inside the slide groove, and the slider is elastically connected to the upper end of the inner wall of the slide groove through a second spring.
[0015] By adopting the above technical solution, the spring can act as a buffer when the cutter is working, reducing the impact force on the cutter and avoiding damage to the cutter due to excessive instantaneous impact force, thus extending the service life of the cutter.
[0016] Specifically, the size of the cutter is larger than the size of the feed hole, and the position of the cutter corresponds to the position of the feed hole, and the grinding block is in contact with the outer wall of the cutter.
[0017] By adopting the above technical solution, the cutter size is larger than the feed hole and the position is corresponding, which can ensure that the masterbatch is completely cut when passing through the feed hole, ensuring the quality of the pellets and the regularity of the pellets. In addition, when the cutter moves, the grinding block continuously contacts the outer wall of the cutter, continuously grinding to maintain the sharpness of the cutter, thus ensuring a good pelleting effect.
[0018] Specifically, a second spring is provided on one side of the outer wall of the movable rod, and the movable rod is elastically connected to the fixed block through the second spring.
[0019] By adopting the above technical solution, the second spring supports the movable rod, ensuring that the grinding block always remains in contact with the outer wall of the cutter, thus ensuring the grinding stability and grinding effect on the cutter.
[0020] The beneficial effects of this utility model are:
[0021] (1) The blade adjustment structure of the masterbatch processing pelletizing device described in this utility model has a slider and a groove that can provide a buffer distance for the cutter, while the first spring can buffer and automatically adjust the cutter, avoid the blade from wearing out too quickly due to uneven local force, improve the force condition of the blade, and extend its service life.
[0022] (2) The blade adjustment structure of the masterbatch processing pelletizing device of the present invention allows the blade surface to contact the outer wall of the grinding block during vertical movement, thereby grinding the outer wall of the blade during the working process, ensuring the sharpness of the blade, extending the service life of the blade, and ensuring the pelletizing quality.

Detailed Implementation
[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the blade adjustment structure for a masterbatch processing pelletizing device of this utility model includes a processing table 1, a baffle plate 2, and a frame 3. A material support plate 11 is screwed to the upper outer wall of the processing table 1. A discharge port 14 is opened on the outer wall of the processing table 1 away from the material support plate 11. A baffle plate 2 is screwed to the upper outer wall of the material support plate 11. A frame 3 is screwed to the upper outer wall of the processing table 1. A support plate 32 is provided inside the frame 3. A sliding groove 33 is provided on the outer wall of the support plate 32. A slider 34 is slidably installed inside the sliding groove 33. A cutter 36 is installed on the lower outer wall of the slider 34. Fixing blocks 21 are installed on both sides of the upper outer wall of the baffle plate 2. A movable rod 22 is movably installed inside the fixing block 21. A connecting plate 24 is screwed to the outer wall of one end of the movable rod 22. A grinding block 25 is installed on the outer wall of the connecting plate 24.
[0032] During use, the support plate 11 can support the material column to be cut, and the cut masterbatch can be discharged through the discharge port 14, which facilitates the subsequent collection of masterbatch by the staff through the collection box and discharge port 14. The cutter 36 can move vertically with the support plate 32, and the slider 34 and the groove 33 can provide a buffer distance for the cutter 36. The first spring 23 can buffer and automatically adjust the cutter 36, avoid the blade from wearing too fast due to uneven local force, improve the force condition of the blade, and extend its service life. During the vertical movement, the surface of the cutter 36 contacts the outer wall of the grinding block 25, which can grind the outer wall of the cutter 36 during the operation of the cutter 36, ensure the sharpness of the cutter 36, extend the service life of the cutter 36, and ensure the quality of the cut particles.
[0033] For unloading, for example, such as Figure 2 As shown, a baffle 13 is screwed to one side of the upper outer wall of the processing table 1. The inner wall size of the baffle 13 is larger than the size of the unloading port 14, and the baffle 13 is located on the outer side of the upper end of the unloading port 14.
[0034] When in use, the baffle 13 can effectively prevent the cut masterbatch from scattering in all directions during the unloading process, ensuring that the masterbatch is smoothly collected to the unloading port 14, keeping the working environment clean and reducing material waste.
[0035] For smooth movement of the material column, for example, such as Figure 2 As shown, the lower outer wall of the baffle plate 2 and the upper outer wall of the support plate 11 are provided with equidistant parallel material feeding holes 12, which are designed in an arc shape.
[0036] During use, the accompanying pusher device can push the material column inside the feed hole 12 to move, driving the masterbatch to move on the support plate 11 towards the cutter 36. The baffle plate 2, together with the support plate 11, can limit the material column, preventing it from tilting up during the cutting process and ensuring the cutting quality of the material column. The arc shape facilitates material movement and ensures the continuity and efficiency of the pelletizing process.
[0037] To drive movement, for example, such as Figure 3 As shown, the frame 3 is located outside the baffle plate 2. Both sides of the outer wall of the frame 3 are screwed with hydraulic cylinders 31. The lower outer wall of the hydraulic cylinder 31 is connected to the upper outer wall of the support plate 32.
[0038] During use, the hydraulic cylinder 31 is controlled by the matching hydraulic control device, thereby driving the support plate 32 to move vertically. The working height of the support plate 32 and the cutter 36 can be adjusted to ensure the pelletizing requirements of the masterbatch.
[0039] To cushion the impact, for example, such as Figure 4As shown, a first spring 23 is provided inside the slide groove 33, and the slider 34 is elastically connected to the upper end of the inner wall of the slide groove 33 through a second spring 35.
[0040] When in use, the spring acts as a buffer to reduce the impact force on the cutter 36 during operation, preventing damage to the cutter 36 due to excessive instantaneous impact force and extending the service life of the cutter 36.
[0041] For polishing, for example, such as Figure 5 As shown, the size of the cutter 36 is larger than the size of the feed hole 12, and the position of the cutter 36 corresponds to the position of the feed hole 12. The grinding block 25 is in contact with the outer wall of the cutter 36.
[0042] When in use, the cutter 36 is larger than the feed hole 12 and is positioned accordingly, which ensures that the masterbatch is completely cut when passing through the feed hole 12, ensuring the quality and regularity of the pellets. When the cutter 36 moves, the grinding block 25 continuously contacts the outer wall of the cutter 36, continuously grinding to keep the cutter 36 sharp, thus ensuring a good pelleting effect.
[0043] To maintain the usage location, for example, such as Figure 5 As shown, a second spring 35 is provided on one side of the outer wall of the movable rod 22, and the movable rod 22 is elastically connected to the fixed block 21 through the second spring 35.
[0044] During use, the second spring 35 supports the movable rod 22, ensuring that the grinding block 25 remains in contact with the outer wall of the cutter 36, thus ensuring the grinding stability and grinding effect of the cutter 36.
[0045] When using this utility model, the operator places the material column to be cut on the support plate 11 and inside the material feeding hole 12. The baffle plate 2 limits the material column to prevent it from tilting up during the cutting process. The matching pushing device starts to work, pushing the material column inside the material feeding hole 12 to move on the support plate 11 towards the cutter 36.
[0046] The operator operates the matching hydraulic control device to control the hydraulic cylinder 31 to work. The hydraulic cylinder 31 drives the support plate 32 to move vertically. The cutter 36 follows the support plate 32 to move vertically. When it moves downward to contact and cut the material column, the first spring 23 in the slide groove 33 can play a buffering role to reduce the impact force on the cutter 36.
[0047] Meanwhile, during the vertical movement of the cutter 36, the second spring 35 supports the movable rod 22, ensuring that the grinding block 25 remains in contact with the outer wall of the cutter 36. Thus, the grinding block 25 grinds the outer wall of the cutter 36 while it is working, ensuring the sharpness of the cutter 36.
[0048] The cut masterbatch is blocked by the baffle 13 and discharged through the discharge port 14.
