Description

Technical Field

[0001] This utility model relates to the field of hollow roller production technology, specifically a hollow roller production device. Background Technology

[0002] Hollow rollers are common industrial components widely used in various mechanical equipment, such as printing presses, papermaking machines, and textile machinery. They are typically used for material transfer, tension regulation, or as support structures. The production equipment for hollow rollers is crucial to ensuring their quality and performance.

[0003] Traditional plate roll cores are solid, meaning they are made of solid materials and have no hollow sections. The disadvantages of this design are its greater weight, which can increase transportation costs and make it more difficult to use. Furthermore, solid rolls may limit performance in certain applications, such as those requiring lightweight construction or specific strength ratios.

[0004] To address the aforementioned issues, a hollow roller production device is proposed, which can produce rollers with a hollow center, thereby reducing weight and lowering costs. Utility Model Content

[0005] The purpose of this invention is to provide a hollow roller production device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hollow roller production apparatus, comprising:

[0008] The bottom box has a base fixedly installed at its bottom and a support plate fixedly installed at its top. A guide groove is provided on the support plate. A threaded rod is rotatably installed inside the guide groove. A movable block is sleeved on the outer wall of the threaded rod and is slidably installed in the guide groove.

[0009] A motor is fixedly installed inside the base box, and the drive end of the motor passes through the base box and the support plate in sequence and extends into the guide groove to be fixedly connected to the bottom end of the threaded rod. Fixing frames are fixedly installed on both sides of the movable block, and a lower mold is provided on the fixing frame. A mold core is provided inside the lower mold.

[0010] A fixing plate is fixedly installed on the upper part of both sides of the support plate, and a symmetrically distributed connecting rod is fixedly installed on the bottom of the fixing plate. An upper mold is provided at the bottom end of the connecting rod, and the upper mold is located directly above the lower mold.

[0011] Preferably, a mounting plate is fixedly installed on the top of the support plate, and fans are fixedly installed on both sides of the bottom of the mounting plate.

[0012] Preferably, the lower mold has an annular top plate inside, and the outer wall of the annular top plate is slidably connected to the inner wall of the lower mold. The inner diameter of the annular top plate is adapted to the outer diameter of the mold core, and the annular top plate is slidably sleeved on the outer wall of the mold core. The bottom of the lower mold has symmetrically distributed guide holes. The bottom of the annular top plate is fixedly installed with guide rods corresponding to the position and number of guide holes, and the guide rods are slidably inserted into the guide holes at the corresponding positions.

[0013] Preferably, reinforcing blocks are fixedly installed on both sides inside the base box, and a removable cover plate is provided on the front of the base box.

[0014] Preferably, the upper mold is fixedly installed to the bottom end of the connecting rod by bolts, and the lower mold is fixedly connected to the fixing frame by bolts.

[0015] Preferably, the lower mold and the mold core are integrally formed, the upper mold is in the shape of an annular plate, the outer diameter of the upper mold is adapted to the inner diameter of the lower mold, and the inner diameter of the upper mold is adapted to the outer diameter of the mold core.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model utilizes a combination of a base box, base, support plate, threaded rod, guide groove, movable block, lower mold, upper mold, fixed frame, mold core, fixed plate, and connecting rod. During operation, the ingenious cooperation between the mold core and the lower mold creates an annular space of a specific depth within the lower mold. This allows the injected raw material to be precisely molded into a hollow roller. This not only effectively solves the problems of heavy weight and high cost associated with traditional solid roller cores but also significantly improves roller performance and production flexibility. The entire process is compact and efficient, ensuring product quality while optimizing production efficiency and costs.

[0018] 2. This invention utilizes a mounting plate and a fan in conjunction. During the cooling and forming process of the hollow roller inside the lower mold, the fan is activated, generating a high-speed airflow that directly blows onto the area of ​​the lower mold, accelerating the airflow around it. This air-cooling method rapidly dissipates heat from the raw material, significantly increasing the forming speed of the hollow roller. It not only optimizes cooling efficiency but also ensures that the hollow roller quickly reaches the required hardness and strength during the forming process, thereby improving overall production efficiency and product quality.

[0019] 3. By using the guide rod, the annular top plate and the guide hole in combination, the annular top plate can directly eject the hollow roller formed inside the lower mold, which greatly improves the demolding speed of the device, effectively avoids the tedious process of manual demolding in the later stage, further improves the production efficiency of the device, and enhances its practicality and automation.

[0031] A hollow roller production apparatus, comprising:

[0032] The bottom box 1 has a base 2 fixedly installed at its bottom and a support plate 3 fixedly installed at its top. A guide groove 5 is provided on the support plate 3. A threaded rod 4 is rotatably installed inside the guide groove 5. A movable block 6 is sleeved on the outer wall of the threaded rod 4 and is slidably installed in the guide groove 5.

[0033] A motor 17 is fixedly installed inside the base box 1, and the drive end of the motor 17 passes through the base box 1 and the support plate 3 in sequence and extends into the guide groove 5 and is fixedly connected to the bottom end of the threaded rod 4. Fixing frames 9 are fixedly installed on both sides of the movable block 6. A lower mold 7 is provided on the fixing frame 9, and a mold core 10 is provided inside the lower mold 7.

[0034] A fixing plate 11 is fixedly installed on the upper part of both sides of the support plate 3. A symmetrically distributed connecting rod 12 is fixedly installed on the bottom of the fixing plate 11. An upper mold 8 is provided at the bottom end of the connecting rod 12, and the upper mold 8 is located directly above the lower mold 7.

[0035] A mounting plate 13 is fixedly installed on the top of the support plate 3, and fans 14 are fixedly installed on both sides of the bottom of the mounting plate 13, which speeds up the forming speed of the hollow roller.

[0036] In one embodiment, the lower mold 7 is provided with an annular top plate 18, and the outer wall of the annular top plate 18 is slidably connected to the inner wall of the lower mold 7. The inner diameter of the annular top plate 18 is adapted to the outer diameter of the mold core 10, and the annular top plate 18 is slidably sleeved on the outer wall of the mold core 10. The bottom of the lower mold 7 is provided with symmetrically distributed guide holes 19. The bottom of the annular top plate 18 is fixedly installed with guide rods 15 corresponding to the position and number of guide holes 19, and the guide rods 15 are slidably inserted into the guide holes 19 at the corresponding positions, thereby realizing rapid demolding.

[0037] In one preferred embodiment, reinforcing blocks 16 are fixedly installed on both sides inside the base box 1, which improves the structural strength of the base box 1. A removable cover plate is provided on the front of the base box 1 to facilitate the inspection and maintenance of its internal mechanical components.

[0038] In one embodiment, the upper mold 8 is fixedly installed to the bottom end of the connecting rod 12 by bolts, and the lower mold 7 is fixedly connected to the fixing frame 9 by bolts, which facilitates the disassembly of the upper mold 8 and the lower mold 7 and supports the rapid replacement of molds of different specifications, thereby improving production flexibility and adaptability.

[0039] In one preferred embodiment, the lower mold 7 and the mold core 10 are integrally formed, and the upper mold 8 is in the shape of an annular plate. The outer diameter of the upper mold 8 is adapted to the inner diameter of the lower mold 7, and the inner diameter of the upper mold 8 is adapted to the outer diameter of the mold core 10. This ensures precise matching between the upper mold 8 and the lower mold 7, as well as between the mold core 10 and the upper mold 8, making the forming of the hollow roller more accurate, while improving the stability and production efficiency of the device.

[0040] The working principle of this utility model is as follows: The entire device is controlled by a main control button. Since the device matched with the control button is a common device and belongs to existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here. The parts of this device not mentioned are the same as existing technology or can be implemented using existing technology. In use, the raw material is heated into a liquid state and then poured into the annular space inside the lower mold 7. At the same time, the motor 17 can be controlled to start working. The drive end of the motor 17 drives the threaded rod 4 to rotate. Through the threaded transmission between the threaded rod 4 and the movable block 6, and the sliding relationship between the movable block 6 and the guide groove 5, the movable block 6 moves vertically stably. The movement of the movable block 6 drives the lower mold 7 to move through the fixed frame 9. At this time, the lower mold 7 is controlled to move upward, so that the upper mold 8 enters the interior of the lower mold 7 through the top opening of the lower mold 7, extruding and cooling the raw material inside the lower mold 7 to form it. During use, through the clever cooperation between the mold core 10 and the lower mold 7, an annular space with a specific depth is created inside the lower mold 7. This allows the injected raw material to be accurately molded into a hollow roller. This not only effectively solves the problems of heavy weight and high cost of traditional solid roller cores, but also significantly improves roller performance and production flexibility. The entire process is compact and efficient, ensuring product quality while optimizing production efficiency and costs.

[0041] During operation, as the hollow roller cools and forms inside the lower die 7, the control fan 14 starts working. The activation of the fan 14 generates a high-speed airflow that blows directly onto the area where the lower die 7 is located, accelerating the airflow around the lower die 7. Through this air-cooling method, the heat on the raw material can be quickly dissipated, significantly improving the forming speed of the hollow roller. This not only optimizes cooling efficiency but also ensures that the hollow roller can quickly reach the required hardness and strength during the forming process, thereby improving overall production efficiency and product quality.

[0042] In use, after the hollow roller cools and forms, the lower mold 7 is moved downward by the drive of the motor 17. The upper mold 8 will disengage from the top opening of the lower mold 7. As the lower mold 7 continues to move downward, the guide rod 15 at the bottom of the lower mold 7 will abut against the top of the bottom box 1. Due to the obstruction of the bottom box 1, the guide rod 15 will drive the annular top plate 18 to move upward relative to the lower mold 7 inside it. The annular top plate 18 can directly push out the hollow roller formed inside the lower mold 7, which greatly improves the demolding speed of the device, effectively avoids the tedious process of manual demolding in the later stage, further improves the production efficiency of the device, and enhances its practicality and automation.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
