Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and more specifically, to a motor support platform for a granulator and a granulator. Background Technology

[0002] A granulator is a molding machine that can produce materials into granules of a specific shape. In existing technology, granulation and cutting machines generally use a motor for rotary cutting, with a rotating cutter head mounted at the end of the motor, and blades evenly distributed circumferentially. The motor is typically fixed to an external metal bracket, the height of which is designed based on the height of the extruder and the size of the cutting motor. Because the existing bracket supporting the cutting motor is an external device, during granulation and cutting, the motor's unstable installation causes vibration during cutting, and the inability to synchronize the motor and extruder results in uneven particle size. This uneven particle size leads to unstable performance of plastic products. Smaller particles can improve the strength and hardness of plastic products, but are prone to deformation and cracking; larger particles can make products softer and more ductile, but also reduce their strength and hardness. Secondly, uneven particle size increases difficulties in the production process. If the particle size is inconsistent, under the same pressure and temperature, different sized particles will have different flowability in the molten state, leading to uneven filling and affecting product quality. Simultaneously, the instability of the cutting machine also causes damage to the cutting blades, requiring frequent disassembly and replacement of the motor and blades, wasting manpower and resulting in low production efficiency. Utility Model Content

[0003] To address the technical problems in existing technologies where motor vibration easily leads to uneven particle size and blade damage, this utility model provides a motor support platform for a granulator and a granulator in general. This allows the motor and extruder to be connected as a whole through the motor support platform, reducing motor vibration, resulting in uniform particle size and improving product quality.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a motor support platform for a granulator, including a support plate, a support shaft and a support platform. The upper part of the support plate is fixedly installed at the discharge port of the extruder. One end of the support shaft is fixedly installed at the lower part of the support plate. The support platform is installed on the support shaft. The upper surface of the support platform is provided with an installation structure for installing the motor.

[0005] In this technical solution, the granulator motor support platform is used to install and support the motor and directly connect the motor to the extruder's outlet. During the granulation process, raw materials are typically extruded from the extruder, and then the motor drives the cutting tools to cut the extruded material, thus achieving the granulation function. The support plate is installed at the extruder's outlet, and the motor is mounted on the support platform. The support platform and support plate are connected by a support shaft. The support shaft separates the support platform from the support plate, providing sufficient space between them for installing the cutting tools on the motor and for cutting the extruded material. During the granulation process, even if the motor vibrates, the support plate, through the support shaft and support platform, supports the motor, limiting its vibration and reducing it. This keeps the motor and the extruder's outlet relatively stable, ensuring that motor vibration does not cause the cutting tools to vibrate as well, thus affecting the cutting at the extruder's outlet and guaranteeing stable cutting results. On the other hand, the integrated design of the support plate, support shaft, and support platform allows the motor to be directly connected to the extruder's outlet through the integrated structure. Even if the motor vibrates and the vibration cannot be completely eliminated, the uneliminated vibration can still be transmitted to the extruder's outlet through the integrated structure, causing the extruder's outlet to vibrate along with the motor. This keeps the motor and the extruder's outlet relatively stationary, thus avoiding the situation where relative vibration between the motor and the extruder causes the position of the motor-driven cutter cutting the extruded raw material to change, ultimately resulting in uneven particle size.

[0006] Preferably, the support shaft is slidably connected to the support platform, and the support platform is connected to an adjustment device that limits its position on the support shaft.

[0007] Preferably, at least two support shafts are provided, the two support shafts are parallel to each other and located on the same horizontal plane, and a baffle is fixedly installed on the end of the two support shafts away from the support plate, and the adjustment device is installed on the baffle.

[0008] Preferably, the adjusting device includes an adjusting shaft and an adjusting turntable. The baffle is provided with a mounting hole. The adjusting shaft is inserted into the mounting hole and rotatably connected to the mounting hole. The adjusting shaft is parallel to the support shaft. The adjusting shaft is a threaded rod. The support platform is provided with a threaded hole. The threaded hole is threadedly connected to one end of the adjusting shaft. The adjusting turntable is installed at the other end of the adjusting shaft.

[0009] Preferably, the support platform includes a top plate, a first side plate, and a second side plate. The first side plate is disposed on the bottom surface of the top plate away from the support plate, and the second side plate is disposed on the bottom surface of the top plate opposite to the first side plate. The motor is mounted on the top plate. Both the first side plate and the second side plate are provided with sliding holes, which are slidably connected to the support shaft. The threaded hole is disposed on the first side plate.

[0010] Preferably, the top plate is provided with mounting holes, the mounting structure is the mounting holes, and the mounting holes are fastened to the motor by fastening bolts.

[0011] Preferably, the support plate is a triangular plate structure, with a through hole at the top corner for material to pass through, the top corner of the support plate being fixedly connected to the extruder, and the two bottom corners of the support plate being fixedly connected to the two support shafts respectively.

[0012] This utility model also provides a granulator, including the above-mentioned granulator motor support platform, extruder, motor and cutting box. The granulator motor support platform is installed at the discharge end of the extruder, the motor is installed on the granulator motor support platform, the cutting box is installed between the motor and the extruder, the cutting box is provided with a cutting blade, and the output shaft of the motor is inserted into the cutting box and connected to the cutting blade.

[0013] In this technical solution, the extruder is used to extrude raw materials into the cutting box, where cutting blades are installed to cut the raw materials and achieve granulation. The output shaft of the motor extends into the cutting box and connects to the cutting blades, driving the cutting blades to rotate and thus cut and granulate the raw materials entering the cutting box. The motor is connected to the discharge port of the extruder via a motor support platform of the granulator, ensuring stability between the motor and the discharge port of the extruder and preventing inconsistent sizes of the cut raw materials due to motor vibration.

[0014] Preferably, the cutting box includes a box body with a cutting cavity inside. A feed hole is provided on the side of the box body near the extruder, and the feed hole communicates with the cutting cavity. The feed hole is aligned with the discharge port of the extruder. A shaft hole is provided at the end of the box body near the motor, through which the output shaft of the motor extends into the cutting cavity. The cutting blade is mounted on the end of the motor's output shaft that extends into the cutting cavity. The shaft hole is at the same height as the feed hole. A discharge hole is provided at the bottom of the box body, and the discharge hole communicates with the cutting cavity.

[0015] Preferably, the cutting cavity includes an upper cutting space and a lower discharge space. The feed hole and the rotating shaft hole are both connected to the cutting space. The cutting space is connected to the discharge space. The discharge space has a narrowing structure that is wider at the top and narrower at the bottom. The bottom of the discharge space is connected to the discharge hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the support plate, support shaft, and support platform are integrated, allowing the motor and the extruder's discharge port to be directly connected through an integrated structure. On the one hand, this reduces motor vibration and ensures stable cutting results. On the other hand, any remaining motor vibration can be transmitted to the extruder's discharge port through the integrated structure, causing the extruder's discharge port to vibrate along with the motor. This keeps the motor and the extruder's discharge port relatively stationary, ensuring uniform particle size in the cut. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0024] Example 1

[0025] like Figure 1 , 3As shown, a motor support platform for a granulator includes a support plate 1, a support shaft 2, and a support platform 3. The upper part of the support plate 1 is fixedly installed at the discharge port of the extruder 4. One end of the support shaft 2 is fixedly installed at the lower part of the support plate 1. The support platform 3 is installed on the support shaft 2, and the upper surface of the support platform 3 is provided with an installation structure for mounting a motor 5. The motor support platform for the granulator is used to install and support the motor 5 and directly connect the motor 5 to the discharge port of the extruder 4. In the granulation process, the raw material is generally extruded from the extruder 4, and then the motor 5 drives the cutter to cut the extruded raw material to achieve the granulation function. The support plate 1 is installed at the discharge port of the extruder 4, and the motor 5 is installed on the support platform 3. The support platform 3 and the support plate 1 are connected by the support shaft 2. The support shaft 2 separates the support platform 3 from the support plate 1, so that there is sufficient space between the support platform 3 and the support plate 1 for mounting the cutter on the motor 5 and cutting the raw material extruded by the extruder 4. During the granulation process, even if the motor 5 vibrates, the support plate 1, through the support shaft 2 and the support platform 3, supports the motor 5, limiting its vibration and reducing it. This ensures that the motor 5 and the extruder 4's outlet remain relatively stable, preventing the motor 5's vibration from causing the cutting blade to vibrate and affecting the cutting of the extruder 4's outlet, thus guaranteeing stable cutting results. Furthermore, the integrated design of the support plate 1, support shaft 2, and support platform 3 allows the motor 5 to be directly connected to the extruder 4's outlet via this integrated structure. Even if the motor 5's vibration cannot be completely eliminated, the remaining vibration can be transmitted to the extruder 4's outlet through the integrated structure, causing the extruder 4's outlet to vibrate along with the motor 5. This keeps the motor 5 and the extruder 4's outlet relatively stationary, preventing the relative vibration between the motor 5 and the extruder 4 from altering the position of the cutting blade and ultimately resulting in uneven particle size.

[0026] like Figure 1 As shown, the support shaft 2 is slidably connected to the support platform 3, and the support platform 3 is connected to an adjusting device 6 that adjusts and restricts its position on the support shaft 2. The support platform 3 can slide on the support shaft 2 to adjust the distance between the support platform 3 and the support plate 1, ultimately adjusting the distance between the motor 5 and the discharge port of the extruder 4 located on the support platform 3, to meet the needs of installation, disassembly, and adjustment between the motor 5 and the extruder 4. The support platform 3 is connected to the adjusting device 6, which is used to adjust and restrict the position of the support platform 3 on the support shaft 2. Operators can drive the support platform 3 to move on the support shaft 2 by operating the adjusting device 6. When the position of the support platform 3 does not need to be adjusted, the adjusting device 6 provides support for the position of the support platform 3, restricting its sliding on the support shaft 2.

[0027] like Figure 1 As shown, at least two support shafts 2 are provided. The two support shafts 2 are parallel to each other and located on the same horizontal plane. A baffle 7 is fixedly installed on the end of each support shaft 2 away from the support plate 1, and the adjusting device 6 is installed on the baffle 7. A single support shaft 2 cannot securely install the support platform 3, and the support platform 3 may rotate around a single support shaft 2. Therefore, at least two support shafts 2 are provided, and the support platform 3 is slidably connected to both support shafts 2. This prevents the support platform 3 from rotating around a single support shaft 2 and enhances the support effect on the support platform 3, making the support platform 3 more stable when installed on the support shafts 2. One end of each support shaft 2 is fixedly connected to the support plate 1, and the other end of each support shaft 2 is connected to the baffle 7. On the one hand, the baffle 7 prevents the support platform 3 from moving and sliding off the end of the support shaft 2. On the other hand, the baffle 7 can fix the relative position of the ends of the two support shafts 2 away from the support plate 1, ensuring the overall structural stability of the two support shafts 2.

[0028] like Figure 1 As shown, the support plate 1 is a triangular plate-like structure. A through hole 11 for material to pass through is provided at the apex of the support plate 1. The apex of the support plate 1 is used for fixed connection with the extruder 4, and the two base corners of the support plate 1 are respectively fixedly connected to two support shafts 2. The support plate 1 is used to connect the two support shafts 2 and is fixedly connected to the extruder 4. The through hole 11 on the support plate 1 provides a channel for the raw material extruded by the extruder 4 to pass through. The triangular plate-like structure of the support plate 1 has good stability. The through hole 11 and the two support shafts 2 are respectively located at the three vertices of the triangular structure, evenly distributing the load that the support plate 1 needs to bear.

[0029] Example 2

[0030] This embodiment is similar to Embodiment 1 above, except that, as Figure 1 , 3 As shown, Figure 1As shown, the adjusting device 6 includes an adjusting shaft 61 and an adjusting turntable 62. A mounting hole is provided on the baffle 7. The adjusting shaft 61 is inserted into and rotatably connected to the mounting hole. The adjusting shaft 61 is parallel to the support shaft 2. The adjusting shaft 61 is a threaded rod. A threaded hole is provided on the support platform 3, and the threaded hole is threadedly connected to one end of the adjusting shaft 61. The adjusting turntable 62 is installed on the other end of the adjusting shaft 61. The adjusting shaft 61 is rotatably connected to the mounting hole. The adjusting shaft 61 rotates within the mounting hole but cannot move relative to it, thus fixing its position. The adjusting shaft 61 is threadedly connected to the threaded hole on the support platform 3. Operators can drive the support platform 3 to move by rotating the adjusting shaft 61. When the support platform 3 moves to a preset position, the adjusting shaft 61 abuts against the thread in the threaded hole, thus supporting the position of the support platform 3 and restricting further movement. The adjusting turntable 62 is installed at the end of the adjusting shaft 61 away from the supporting platform 3, making it easy for workers to grasp and rotate the adjusting shaft 61.

[0031] like Figure 3 As shown, the support platform 3 includes a top plate 31, a first side plate 32, and a second side plate 33. The first side plate 32 is located on the bottom surface of the top plate 31 away from the support plate 1, and the second side plate 33 is located on the bottom surface of the top plate 31 opposite to the first side plate 32. The motor 5 is mounted on the top plate 31. Both the first side plate 32 and the second side plate 33 are provided with sliding holes, which are slidably connected to the support shaft 2. A threaded hole is provided on the first side plate 32. The first side plate 32 and the second side plate 33 are connected through the top plate 31. The space between the first side plate 32 and the second side plate 33 is a space for the adjustment shaft 61 to extend into. The threaded hole is provided on the first side plate 32, while the second side plate 33 does not have a structure for the adjustment shaft 61 to pass through. This restricts the movement of the end of the adjustment shaft 61 to only between the first side plate 32 and the second side plate 33, thereby limiting the movement range of the support platform 3.

[0032] like Figure 1 , 3 As shown, the top plate 31 is provided with mounting holes 34. The mounting structure consists of mounting holes 34, which are fastened to the motor 5 by fastening bolts. The motor 5 is fixedly mounted on the top plate 31 by fastening bolts, which facilitates quick installation and removal of the motor 5 by the operators.

[0033] Example 3

[0034] like Figure 2As shown, a granulator includes a granulator motor support platform 9, an extruder 4, a motor 5, and a cutting box 8 as described in the above embodiment. The granulator motor support platform 9 is installed at the discharge end of the extruder 4. The motor 5 is installed on the granulator motor support platform 9. The cutting box 8 is installed between the motor 5 and the extruder 4. A cutting blade is provided inside the cutting box 8. The output shaft of the motor 5 is inserted into the cutting box 8 and connected to the cutting blade. The extruder 4 is used to extrude raw materials into the cutting box 8. The cutting blade inside the cutting box 8 is used to cut the raw materials to achieve the granulation function. The output shaft of the motor 5 extends into the cutting box 8 and is connected to the cutting blade, driving the cutting blade to rotate and thus cutting and granulating the raw materials entering the cutting box 8. The motor 5 is connected to the discharge port of the extruder 4 through the granulator motor support platform 9, ensuring that the distance between the motor 5 and the discharge port of the extruder 4 remains stable and that the cut raw materials are not uneven in size due to vibration of the motor 5.

[0035] like Figure 3 As shown, the cutting box 8 includes a box body with a cutting cavity inside. A feed hole is located on the side of the box body near the extruder 4, communicating with the cutting cavity and aligned with the discharge port of the extruder 4. A shaft hole is located at the end of the box body near the motor 5, through which the output shaft of the motor 5 extends into the cutting cavity. The cutting blade is mounted on the end of the motor 5's output shaft that extends into the cutting cavity. The shaft hole is at the same height as the feed hole. A discharge hole is located at the bottom of the box body, communicating with the cutting cavity. The cutting cavity inside the cutting box 8 is a semi-enclosed space, separating the process of cutting the raw material extruded by the extruder 4 from the outside environment. This prevents raw material from splashing into the external space during cutting and also prevents external structures from accidentally extending near the cutting blade and causing damage. The raw material extruded by the extruder 4 passes through the feed hole and enters the cutting cavity through the box body. The output shaft of the motor 5 can extend into the cutting cavity through the shaft hole to drive the cutting blade to rotate and cut the raw material.

[0036] like Figure 3 As shown, the cutting chamber includes an upper cutting space and a lower discharge space. The feed hole and shaft hole are both connected to the cutting space, which in turn is connected to the discharge space. The discharge space has a tapered structure, wider at the top and narrower at the bottom, and its bottom is connected to the discharge hole. The cutting space is used to accommodate the rotating cutting blade, the cutting action, and the raw material extruded from the extruder 4. The cut raw material falls into the discharge space, which has a tapered structure, wider at the top and narrower at the bottom, facilitating the collection of the cut material.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
