Description

Technical Field

[0001] This utility model relates to the field of height adjustment equipment technology, specifically to a device for adjusting the height of the granulation forming roller in a calcium-zinc stabilizer granulator. Background Technology

[0002] A granulator is a molding device that can shape materials into specific shapes. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, rubber, and plastics industries. Granulators are also frequently used in the production and processing of PVC product raw materials, such as PVC resin and calcium-zinc stabilizers, which require granulation for shaping.

[0003] The granulation forming roller is a key component in a granulator used for material shaping, such as... Figure 1 The granulation forming roller shown is used in a calcium-zinc stabilizer granulator and includes a roller body A and a central shaft B. The central shaft B is located on the axial center line of the roller body A. At one end of the central shaft B extending outside one end face of the roller body A, there are sequentially arranged an annular section B-1, a smooth section B-2, and a screw section B-3. The outer diameter of the annular section B-1 is greater than the outer diameter of the central shaft B, which is greater than the outer diameter of the smooth section B-2, which is greater than the outer diameter of the screw section B-3. At the other end of the central shaft B extending outside the other end face of the roller body A, there is a screw section B-4. Figure 2 As shown, when the granulating forming roller of this structure is installed inside the machine compartment C of the calcium-zinc stabilizer granulator, the screw section B-3, smooth section B-2, and ring section B-1 located at one end of the central shaft B are sequentially inserted into the three-stage stepped mounting holes on the vertical bottom surface of the machine compartment C. The end of the central shaft B with screw section B-4 faces the outer port of the machine compartment C. Currently, when this granulating forming roller is installed inside the machine compartment C of the calcium-zinc stabilizer granulator, because the outer diameters of the screw section B-3, smooth section B-2, and ring section B-1 increase sequentially, it is necessary to manually and continuously adjust the position and height of the roller body A to ensure the concentricity of the screw section B-3, smooth section B-2, and ring section B-1 with the three-stage stepped mounting holes, thereby ensuring that the three sections are properly inserted into the three-stage stepped mounting holes. The problems with this installation method are: (1) The internal space of the granulator chamber is relatively small, making it inconvenient to adjust the position and height of roller A using existing lifting devices. Due to the large weight of roller A, there is a safety hazard of slippage and injury to the operator's feet when manually holding roller A to adjust its position and height; (2) When manually adjusting the position and height of roller A, the height adjustment distance is difficult to control, requiring constant attempts to center it, which is difficult to operate, inefficient, and seriously restricts the assembly efficiency of the granulator. Therefore, this utility model proposes a device for adjusting the height of the granulating forming roller in a calcium-zinc stabilizer granulator in order to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a device for adjusting the height of the granulating forming roller in a calcium-zinc stabilizer granulator. In use, the device is placed in the center of the bottom of the granulator's chamber. Then, the granulating forming roller is placed inside the storage cavity, with its outer peripheral side abutting against two opposing inclined surfaces on two support beams. The spacing between the two support beams, i.e., the lateral width of the storage cavity, is flexibly adjusted via a spacing adjustment mechanism. This allows for flexible adjustment of the roller's height, ensuring the alignment of the roller's internal central axis with the three-section stepped mounting holes on the vertical bottom surface of the chamber, thus guaranteeing the proper functioning of the roller's internal central axis. One end of the roller, consisting of a screw section, a smooth section, and a ring platform section, can be quickly and smoothly inserted into the three-stage stepped mounting holes on the vertical bottom surface of the machine compartment. Compared to manually holding and adjusting the roller height, this significantly reduces the burden of manual operation, eliminates the risk of the roller slipping and injuring the operator, and ensures good safety during operation. The height of the roller can be adjusted gradually, making it easier to quickly find the alignment between the roller's internal central axis and the three-stage stepped mounting holes on the vertical bottom surface of the machine compartment, thus improving the installation efficiency of the granulation forming roller. The compact and reasonable structural design and small overall size allow it to be placed and used in confined spaces such as the bottom of the granulator compartment, making it highly feasible and practical.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a device for adjusting the height of the granulation forming roller in a calcium-zinc stabilizer granulator, including a base plate and two support beams. One support beam is laid on the left side of the upper surface of the base plate along the longitudinal direction, and the other support beam is laid on the right side of the upper surface of the base plate along the longitudinal direction. The opposing sides of the two support beams are both set as inclined surfaces that gradually extend from top to bottom. The gap between the inclined surfaces on the two support beams forms a storage cavity for accommodating the roller body on the granulation forming roller. A spacing adjustment mechanism for adjusting the lateral width of the storage cavity is provided between the base plate and the two support beams.

[0006] This invention relates to a device for adjusting the height of the granulating forming roller in a calcium-zinc stabilizer granulator. In use, the device is placed at the center of the bottom of the granulator's chamber. The granulating forming roller is then placed inside the storage cavity, with its outer peripheral side abutting against two opposing inclined surfaces on two support beams. A spacing adjustment mechanism allows for flexible adjustment of the spacing between the two support beams, i.e., the lateral width of the storage cavity. This enables flexible adjustment of the roller's height, ensuring alignment between the roller's internal central axis and the three-section stepped mounting holes on the vertical bottom surface of the chamber. This ensures the roller's internal central axis has a screw section, a smooth section, and... One end of the ring section can be quickly and easily inserted into the three-stage stepped mounting holes on the vertical bottom surface of the machine compartment. Compared with the method of manually holding and adjusting the height of the roller, this greatly reduces the burden of manual operation, eliminates the risk of the roller slipping and injuring the operator, and ensures good safety during operation. The height of the roller can be adjusted gradually, which makes it easier to quickly find the alignment position between the central axis inside the roller and the three-stage stepped mounting holes on the vertical bottom surface of the machine compartment, thus improving the installation efficiency of the granulation forming roller. The structure is compact and reasonable, and the overall size is small, so it can be placed and used in narrow spaces such as the bottom of the granulator compartment. It is highly feasible to implement and has strong practicality.

[0007] A preferred technical solution is that the upper surface of the base plate is provided with a sliding groove along the left-right transverse direction. Two sliders are slidably installed inside the sliding groove. Internally threaded sleeves are fixedly mounted on the lower ends of the two support beams respectively. The lower end of the internally threaded sleeve on the left support beam is fixedly connected to the upper end of the slider on the left side of the sliding groove, and the lower end of the internally threaded sleeve on the right support beam is fixedly connected to the upper end of the slider on the right side of the sliding groove. The system also includes an adjusting screw with positive and negative threads at both ends. The internally threaded sleeve on the lower end of the left support beam is screwed onto the left end of the adjusting screw, and the internally threaded sleeve on the lower end of the right support beam is screwed onto the right end of the adjusting screw. The sliding groove, the two sliders, the internally threaded sleeves on the lower ends of the two support beams, and the adjusting screw constitute a set of the spacing adjustment mechanism. The spacing adjustment mechanism has a clever and reasonable structural design. The spacing between the two support beams can be adjusted by rotating the adjusting screw. It is simple to operate, requires low operator skill, and is highly practical.

[0008] A further preferred technical solution is that the spacing adjustment mechanism comprises two sets: one set located at the rear end of the base plate and the two support beams, and the other set located at the front end of the base plate and the two support beams. Having two sets of spacing adjustment mechanisms located on the front and rear sides of the base plate helps ensure the stability of the two support beams when they support the granulation forming roller and move relative to each other.

[0009] A further preferred technical solution is that both ends of the adjusting screw are equipped with handwheels. The handwheels improve the ease of operation when adjusting the distance between the two support beams by rotating the adjusting screw.

[0010] A further preferred technical solution is that the cross-section of the chute is an inverted T-shaped groove structure, and the cross-section of the slider is a rectangular structure adapted to the horizontal groove at the bottom of the inverted T-shaped structure. The lower end of the internal threaded sleeve moves through the vertical groove of the inverted T-shaped structure and is fixedly connected to the top of the slider. The fit and stability between the slider and the chute are good, further ensuring the smoothness and safety of the relative movement of the two support beams bearing the granulation forming rollers.

[0011] A further preferred technical solution is that the supporting beam is a channel steel structure with its opening facing downwards, and the lower edges of the arm plates on both sides of the supporting beam are overlapped and welded to the top of the internal threaded sleeve. The use of channel steel for the supporting beam allows the opposing sides of the two supporting beams to naturally form inclined surfaces, ensuring the ease of preparation and implementation of the device for adjusting the height of the granulation forming roller in the calcium-zinc stabilizer granulator of this invention.

[0012] A further preferred technical solution is that the outer surface of the support beam is provided with an anti-corrosion and wear-resistant coating. This coating helps improve the wear and corrosion resistance of the inclined surface of the support beam, extending its service life.

[0013] A further preferred technical solution is that a handle is provided at the outer periphery of the upper surface of the base plate. The handle improves the ease of handling and carrying of the device for adjusting the height of the granulation roller in the calcium-zinc stabilizer granulator.

[0014] The advantages and beneficial effects of this utility model are as follows:

[0015] 1. This utility model discloses a device for adjusting the height of the granulating forming roller in a calcium-zinc stabilizer granulator. In use, the device is placed at the center of the bottom of the granulator's chamber. The roller body of the granulating forming roller is then placed inside the storage cavity. The outer peripheral side of the roller body abuts against two opposing inclined surfaces on two support beams. The spacing between the two support beams, i.e., the lateral width of the storage cavity, is flexibly adjusted via a spacing adjustment mechanism. This allows for flexible adjustment of the roller body's height, ensuring alignment between the roller's internal central axis and the three-section stepped mounting holes on the vertical bottom surface of the chamber. This ensures the roller's internal central axis has a screw section and a smooth section. One end of the roller can be quickly and easily inserted into the three-stage stepped mounting holes on the vertical bottom surface of the machine compartment. Compared with the method of manually holding and adjusting the height of the roller, this greatly reduces the burden of manual operation, eliminates the risk of the roller slipping and injuring the operator, and ensures good safety during operation. The height of the roller can be adjusted gradually, which makes it easier to quickly find the alignment position between the central axis inside the roller and the three-stage stepped mounting holes on the vertical bottom surface of the machine compartment, thus improving the installation efficiency of the granulation forming roller. The structure is compact and reasonable, and the overall size is small, so it can be placed and used in narrow spaces such as the bottom of the granulator compartment. It has high feasibility and strong practicality.

[0016] 2. The spacing adjustment mechanism has a clever and reasonable structural design. The spacing between the two support beams can be adjusted by rotating the adjusting screw. It is simple to operate, requires low technical skills from the operator, and is highly practical. The spacing adjustment mechanism is set up in two sets on the front and rear sides of the base plate, which helps to ensure the stability of the two support beams when they support the granulation forming roller and move relative to each other. The handwheel improves the convenience of operation when adjusting the spacing between the two support beams by rotating the adjusting screw.

[0017] 3. The chute has an inverted T-shaped cross-section, and the slider has a rectangular cross-section that matches the horizontal groove at the bottom of the inverted T-shaped structure. The lower end of the internal threaded sleeve moves through the vertical groove of the inverted T-shaped structure and is fixedly connected to the top of the slider. The slider and chute have good compatibility and stability, further ensuring the smoothness and safety of the relative movement of the two support beams supporting the granulation forming rollers.

[0018] 4. The supporting beam is a channel steel structure with its opening facing downwards. The lower edges of the arm plates on both sides of the supporting beam overlap and are welded and fixed to the top of the internal threaded sleeve. The use of channel steel structure for the supporting beam allows the two opposing sides of the two supporting beams to naturally form inclined surfaces, ensuring the ease of preparation and implementation of the device for adjusting the height of the granulation forming roller in the calcium-zinc stabilizer granulator.

[0037] The working principle of the device for adjusting the height of the granulation roller in a calcium-zinc stabilizer granulator according to this utility model is as follows:

[0038] Step 1: When using, place the device for adjusting the height of the granulation forming roller in the calcium-zinc stabilizer granulator at the center of the bottom of the machine compartment C of the calcium-zinc stabilizer granulator, and position the handwheel 7 at the left and right ends of the machine compartment C. Rotate the handwheel 7 to adjust the lateral width of the storage cavity 6 between the two support beams 2 to the maximum limit position.

[0039] Step 2: Hoist the granulation forming roller into the machine compartment C, and place roller A inside the storage cavity 6 of the device for adjusting the height of the granulation forming roller in the calcium-zinc stabilizer granulator of this invention, with the end of the central shaft B having the screw section B-4 facing forward (see appendix). Figure 7 );

[0040] Step 3: Rotate the handwheel 7 located on the rear side to move the rear ends of the two support beams 2 inward and bring them closer together by a certain distance. Similarly, rotate the handwheel 7 located on the front side to move the front ends of the two support beams 2 inward and bring them closer together by a certain distance, thereby raising the roller A by a certain distance.

[0041] Step 4: Push roller A from front to back. If the rear end of the central shaft B cannot be smoothly inserted into the three-stage stepped mounting hole on the vertical bottom surface of the machine compartment C due to insufficient upward adjustment, continue to refer to Step 3 to raise the roller body a certain distance again, and then push roller A from front to back until the rear end of the central shaft B can be smoothly inserted into the three-stage stepped mounting hole on the vertical bottom surface of the machine compartment C. Take out the device for adjusting the height of the granulating forming roller in the calcium-zinc stabilizer granulator of this utility model and carry out the subsequent installation operation.

[0042] Push roller A from front to back. If the rear end of the central shaft B cannot be smoothly inserted into the three-stage stepped mounting hole on the vertical bottom surface of the machine compartment C due to excessive upward adjustment, rotate the handwheel 7 on the rear side in the opposite direction to move the rear ends of the two support beams 2 slightly away from each other. Similarly, rotate the handwheel 7 on the front side in the opposite direction to move the front ends of the two support beams 2 slightly away from each other. After lowering roller A by a certain distance, try pushing roller A from front to back until the rear end of the central shaft B is smoothly inserted into the three-stage stepped mounting hole on the vertical bottom surface of the machine compartment C. Remove the device for adjusting the height of the granulating roller in the calcium-zinc stabilizer granulator of this utility model and proceed with the subsequent installation operations.

[0043] This invention relates to a device for adjusting the height of the granulating forming roller in a calcium-zinc stabilizer granulator. In use, the device is placed at the center of the bottom of the granulator's chamber. The granulating forming roller is then placed inside the storage cavity, with its outer peripheral side abutting against two opposing inclined surfaces on two support beams. A spacing adjustment mechanism allows for flexible adjustment of the spacing between the two support beams, i.e., the lateral width of the storage cavity. This enables flexible adjustment of the roller's height, ensuring alignment between the roller's internal central axis and the three-section stepped mounting holes on the vertical bottom surface of the chamber. This ensures the roller's internal central axis has a screw section, a smooth section, and... One end of the ring section can be quickly and easily inserted into the three-stage stepped mounting holes on the vertical bottom surface of the machine compartment. Compared with the method of manually holding and adjusting the height of the roller, this greatly reduces the burden of manual operation, eliminates the risk of the roller slipping and injuring the operator, and ensures good safety during operation. The height of the roller can be adjusted gradually, which makes it easier to quickly find the alignment position between the central axis inside the roller and the three-stage stepped mounting holes on the vertical bottom surface of the machine compartment, thus improving the installation efficiency of the granulation forming roller. The structure is compact and reasonable, and the overall size is small, so it can be placed and used in narrow spaces such as the bottom of the granulator compartment. It is highly feasible to implement and has strong practicality.
