Description

Technical Field

[0001] This utility model relates to the field of pelletizing equipment technology, and in particular to a pelletizing device that prevents sticking. Background Technology

[0002] In the production and processing of rubber and plastics, workers often need to change the proportion of ingredients according to processing requirements to make granular raw materials, and then use the granular raw materials for specific production and processing. The ingredients usually need to be heated and extruded into strips, cooled, and then cut into granules using pelletizing equipment.

[0003] When raw materials are cut into granules, some of the raw material particles will stick to the cutting tool. The raw material particles stuck to the cutting tool will interfere with subsequent work, which may result in the raw material particles being cut into different sizes and reducing the cutting accuracy. At this time, it is necessary to stop the machine to clean the sticky raw material particles. Therefore, there is a need for a pelletizing device that can avoid sticking to the cutting tool and avoid affecting the cutting accuracy. Utility Model Content

[0004] The purpose of this invention is to provide an anti-sticking pelletizing device, which aims to solve the problem that raw material particles sticking to the cutting tool affect the subsequent cutting accuracy.

[0005] To achieve the above objectives, this utility model provides an anti-sticking pelletizing device, including a base, a support plate on the base, and a cutting blade and a cleaning assembly mounted on the support plate. The cleaning assembly includes a reciprocating drive, a reciprocating frame, a brush table, a cleaning brush, a high-pressure drive, and a blower. The reciprocating drive and the reciprocating frame are both mounted on the support plate, and the reciprocating frame can slide on the support plate. The reciprocating drive is used to drive the reciprocating frame to reciprocate on the support plate in a direction parallel to the central axis of the cutting blade. The brush table is located at the bottom of the reciprocating frame and is used to mount the cleaning brush, which is used to clean the cutting blade. The high-pressure drive and the blower are both mounted on the support plate.

[0038] The present invention will be described in detail below with reference to specific embodiments.

[0039] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0040] like Figures 1 to 15As shown, this utility model provides an anti-sticking pelletizing device, including a base 1, a support plate 2 on the base 1, a cutting blade 3 and a cleaning assembly 4 mounted on the support plate 2, the cleaning assembly 4 including a reciprocating drive 40, a reciprocating frame 41, a brush table 42, a cleaning brush 43, a high-pressure drive 44 and a blower 45, the reciprocating drive 40 and the reciprocating frame 41 are both mounted on the support plate 2, the reciprocating frame 41 can slide on the support plate 2, the reciprocating drive 40 is used to drive the reciprocating frame 41 to reciprocate on the support plate 2 in a direction parallel to the central axis of the cutting blade 3; the brush table 42 is set at the bottom of the reciprocating frame 41, the brush table 42 is used to mount the cleaning brush 43, the cleaning brush 43 is used to clean the cutting blade 3; the high-pressure drive 44 and the blower 45 are both mounted on the support plate 2, the high-pressure drive 44 is used to provide high-pressure airflow to the blower 45, the nozzles on the blower 45 are directed towards the cutting blade 3.

[0041] In this embodiment, the cutting tool 3 is an alloy hobbing cutter.

[0042] Through the above design, the cutting blade 3 cuts the extruded and cooled strip material into granular material by rotating. The granular material adhering to the cutting blade 3 continues to rotate and reaches the cleaning area of ​​the cleaning assembly 4. The reciprocating drive 40 drives the reciprocating frame 41 to move the cleaning brush 43 in a direction parallel to the central axis of the cutting blade 3. The bristles on the reciprocating cleaning brush 43 can easily clean the granular material adhering to the cutting blade 3, detaching the granular material and preventing it from affecting the subsequent cutting accuracy. Due to the special shape of the cutting blade 3, part of... The granular material that is swept off may not fall off immediately and may remain in the gap between the blades of the cutting blade 3. It may continue to slightly stick to the gap between the blades of the cutting blade 3. As the cutting blade 3 continues to rotate, the granular material that is slightly sticky in the gap will return to the cutting area. In order to prevent this part of the granular material from interfering with the cutting accuracy of the subsequent granular material, the compressed air output by the high-pressure drive 44 is blown towards the cutting blade 3 under the guidance of the blower 45, blowing the granular material that is slightly sticky in the gap to both sides of the cutting blade 3, so that the remaining granular material is blown off from both sides of the cutting blade 3.

[0043] In addition to cleaning sticky granular materials, the cleaning brush 43 can also clean the dust and impurities that stick to the cutting tool 3 during the processing, keeping the surface of the cutting tool 3 clean and further ensuring cutting accuracy.

[0044] In this embodiment, a feeding assembly 5 is provided on the base 1. The feeding assembly 5 includes a feeding frame 50, a feeding roller 51, and an auxiliary roller 52. The feeding frame 50 is fixedly installed on the base 1 and has a roller groove 500. The feeding roller 51 and the auxiliary roller 52 are both installed on the support plate 2, and the feeding roller 51 is placed in the roller groove 500. A sliding groove 12 is provided on the support plate 2. Roller seats are rotatably connected to both ends of the auxiliary roller 52. The roller seats are installed in the sliding groove 12 and can slide up and down in the sliding groove 12. A limit rod 520 and a tensioning elastic member 521 are provided in the sliding groove 12. The limit rod 520 is installed in the sliding groove 12 and the roller seat can slide on the limit rod 520. The tensioning elastic member 521 is sleeved on the limit rod 520. One end of the tensioning elastic member 521 abuts against the sliding groove 12 and the other end abuts against the roller seat.

[0045] Through the above design scheme, the feed roller 51 can actively guide the strip-shaped raw material into the cutting range of the cutting tool 3. The auxiliary roller 52, located above the feed roller 51, can press the strip-shaped raw material onto the feed roller 51 under the action of gravity and the tensioning elastic element 521, ensuring that the strip-shaped raw material will not slip on the feed roller 51. The limiting rod 520 in the slide groove 12 can further improve the smoothness of the roller seat sliding, allowing it to slide freely in the slide groove 12.

[0046] In this embodiment, a feed bar 53 is provided on the base 1, and a feed roller 54 is installed on the feed bar 53; an inclined surface 501 is provided at the front end of the feed bar 53 near the cutting tool 3, and an anvil 502 is provided above the inclined surface 501.

[0047] Through the above design scheme, the feed bar 53 and the distribution roller 54 can guide multiple strip-shaped raw materials to enter the cutting range of the cutting blade 3 in a parallel manner. The inclined surface 501 can guide the cut granular raw materials to slide out of the pelletizing equipment. The anvil 502 on the inclined surface 501 can provide support for the strip-shaped raw materials to be cut, ensuring that the volume of the granular raw materials is close.

[0048] In this embodiment, two sets of gathering plates 55 are provided on the feed bar 53, and the gathering plates 55 can slide on the feed bar 53; a bidirectional lead screw 56 is also provided on the feed bar 53, and handles 57 are provided at both ends of the bidirectional lead screw 56. The bidirectional lead screw 56 is used to control the two sets of gathering plates 55 to move closer or further apart from each other.

[0049] Through the above design scheme, the gathering plate 55 on the feed bar 53 can guide multiple strip-shaped raw materials to move as close as possible to the middle area of ​​the cutting tool 3; the threads at both ends of the bidirectional lead screw 56 are turned in opposite directions, and the user can rotate the bidirectional lead screw 56 by turning the handle 57, thereby causing the gathering plates 55 to move closer or further apart.

[0050] In this embodiment, the feed rack 50 is provided with an air outlet 503, and multiple sets of fans 58 are installed at the bottom of the air outlet 503; both the feed rack 50 and the support plate 2 are provided with air inlets.

[0051] After being extruded, the strip-shaped raw material is at a high temperature and has a soft texture, so it needs to be cooled before it can be cut. There are usually two cooling methods for strip-shaped raw materials: water cooling and air cooling. Water cooling can shorten the cooling time and reduce the equipment footprint, but water will adhere to the surface of the strip-shaped raw material after water cooling. Therefore, a drying device to remove moisture is usually required after the water cooling equipment.

[0052] With the above design, the fan 58 at the bottom of the air outlet 503 can blow the outside airflow toward the strip-shaped raw material passing through the feed chute 53, further ensuring the dryness of the surface of the strip-shaped raw material. At the same time, the fan 58 can also dissipate heat from the strip-shaped raw material, thereby reducing the floor space occupied by the cooling and drying equipment in the whole granulation equipment.

[0053] In this embodiment, the cleaning brush 43 is provided with an installation groove 433, and the brush table 42 is provided with an installation slide rail 422 corresponding to the installation groove 433; the installation slide rail 422 is provided with a limiting protrusion 423, and the installation groove 433 is provided with a limiting groove 434 corresponding to the limiting protrusion 423.

[0054] In this embodiment, the mounting rail 422 is made of rigid plastic, which will deform slightly when subjected to force, ensuring that the protrusion can pass through the part without the limiting groove 434.

[0055] In this embodiment, the brush holder 42 is provided with a storage groove 420, and a locking tongue 421 is provided in the storage groove 420, which can slide in the storage groove 420; the brush is provided with a card slot 430, which is located directly below the storage groove 420, and a button 431 is provided in the card slot 430, which can slide in the card slot 430.

[0056] Through the above design scheme, the locking tongue 421 and the slot 430 can lock the cleaning brush 43, preventing the cleaning brush 43 from falling off when the movement is too large. After long-term processing, the cleaning brush 43 will inevitably curl, and the curled bristles will become entangled, affecting the cleaning of the cutting tool 3. The locking tongue 421 in the storage slot 420 slides down automatically under the action of gravity, causing part of the locking tongue 421 to protrude; when installing the cleaning brush 43, the installation slide rail 422 slides into the installation slot 433, and the installation slot 433 can push the locking tongue 421 into the storage slot 420. As the cleaning brush 43 continues to go deeper, the slot 430 will come to the bottom of the storage slot 420. After losing the restriction of the installation slot 433, the locking tongue 421 extends out and enters the slot 430. At this point, the slot 430 will be locked by the locking tongue 421, preventing the cleaning brush 43 from moving. When it is necessary to remove the cleaning brush 43, the operator can press the button 431. The button 431 rises and pushes the locking tongue 421 out of the slot 430 until the button 431 completely seals the slot 430. After being freed from the restriction of the locking tongue, the cleaning component 4 can slide freely again, making it convenient for the operator to directly remove the cleaning brush 43 from the brush table 42.

[0057] In this embodiment, a handle 432 is provided on the brush table 42, and an operation port 10 is provided on the support plate 2 at the corresponding handle 432. A door panel 11 is provided at the operation port 10, and the door panel 11 can slide in the operation port 10.

[0058] With the above design, the handle 432 on the brush table 42 can be easily held by the operator, the door panel 11 on the support plate 2 can be easily replaced with brushes, and the door panel 11 at the operating port 10 can block the operating port 10 to prevent granular raw materials from accidentally falling from the operating port 10 to the outside during the processing.

[0059] In this embodiment, a protective cover 6 is provided on the support plate 2, and a feeding port 13 is provided on the base 1, with the feeding port 13 located directly below the cutting tool 3.

[0060] In this embodiment, both the cutting tool 3 and the feeding roller 51 are equipped with electric rollers, the reciprocating drive 40 is preferably a reciprocating motor, and the high-pressure drive 44 is preferably an air pump.

[0061] The present invention provides an anti-sticking pelletizing device. Compared with the prior art, the reciprocating drive 40 drives the reciprocating frame 41 to drive the cleaning brush 43 to move back and forth. The reciprocating cleaning brush 43 can brush over the surface of the cutting blade 3. When the granular material stuck to the cutting blade 3 passes through the cleaning area, the cleaning brush 43 can easily clean off the stuck granular material. Some of the cleaned granular material will fall into the feed port 13 during the cleaning process. Some granular material may stick slightly to the cutting blade 3. The compressed gas blown out by the high-pressure drive 44 is blown towards the cutting blade 3 by the blowing column 45, blowing off the granular material that is slightly stuck to the cutting blade 3, ensuring that the granular material being cut will not interfere with the subsequent cutting work, thereby ensuring the production accuracy of continuously cut granular material.

[0062] Where there is no conflict, the above embodiments and features can be combined with each other.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
