Abstract
Description
Technical Field
[0001] This utility model belongs to the field of roller technology, and in particular relates to an adjustable angle roller. Background Technology
[0002] A roller is a mechanical component with a rotating function, widely used in various mechanical equipment, especially for transmission, support, and processing. It is typically made of steel or other robust metal materials, possessing high strength and durability. Rollers are generally used to support rollers, and their rotation enables functions such as material transfer, heating, cooling, compression, and separation.
[0003] According to the public announcement (Announcement No.: CN211684041U), an adjustable roller printing machine includes a printing machine body, a take-up structure, an upper roll plate, a lower roll plate, a rotating rod, a nut, a motor, a support base, a fixing sleeve, a limiting block, a gear, saw teeth, a limiting rod, and a drying structure. The beneficial effects of this utility model are: a rotating rod is rotatably connected inside the lower roll plate, a gear is fixedly connected to the outside of the rotating rod, a limiting rod is slidably connected inside the lower roll plate, one end of the limiting rod is fixedly connected to the upper roll plate, and multiple saw teeth are fixedly connected to one side of the limiting rod. These saw teeth mesh with the gear, which facilitates the rotation of the rotating rod, causing the gear to rotate and mesh with the saw teeth, thereby adjusting the distance between the upper and lower roll plates. This prevents the fabric rolled up on the surfaces of the upper and lower roll plates from contacting the roll plates, making it easier to remove the rolled-up fabric. The combined use of the drying structure and the take-up structure facilitates the drying of the printed fabric, preventing damage to the fabric due to undried ink during take-up.
[0004] The aforementioned patent achieves the effect of adjusting the upper and lower winding plates to facilitate the removal of the rolled-up fabric by cooperating with components such as the upper winding plate, lower winding plate, and rotating rod. However, it cannot achieve a better effect of adjusting the roller shaft angle. Therefore, we propose an adjustable roller shaft. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable angle roller, thereby solving the existing problems.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is an adjustable angle roller, including a support leg, a fixing frame is provided on the side of the support leg, the roller is rotatably connected to the inner side of the fixing frame, and an angle adjustment device is provided on the side of the support leg.
[0008] The angle adjustment device includes a groove formed on the side of the support leg. A rack is slidably connected to the inner side of the groove. A rotating shaft is connected through the side of the support leg. A gear is fixedly connected to the circumferential surface of the rotating shaft. A connecting rod is fixedly connected to the side of the rack, and a connecting column is fixedly connected to one end of the connecting rod. This device, through the linkage of the gear and rack, can precisely adjust the angle of the roller, thereby enabling the adjustable roller to adjust its angle according to different working requirements, adapting to different processing, conveying, and winding needs.
[0009] Furthermore, four support legs are provided, and sliding grooves are formed on the sides of two of the support legs. The function of the sliding grooves is to provide a precise and stable guiding and adjustment channel, ensuring that the roller can move smoothly during angle adjustment, thereby improving the performance and durability of the device.
[0010] Furthermore, four connecting columns are provided. Two of the connecting columns have one end slidably connected to the sliding groove, and the other four connecting columns have one end fixedly connected to the side of the fixing frame. The function of the connecting columns is to connect and support multiple key components, facilitate angle adjustment, and ensure the stability, balance, and accuracy of the system.
[0011] Furthermore, the gear meshes with the rack, and a handle is fixedly connected to one end of the rotating shaft. The meshing of the gear and rack, along with the manual control achieved through the rotating shaft and handle, provides an intuitive and precise adjustment method. This design not only enhances the ease of operation but also improves the accuracy and efficiency of adjustment, making the entire system more stable and reliable.
[0012] Furthermore, two of the aforementioned grooves, racks, shafts, connecting rods, gears, and handles are provided. These two grooves, racks, shafts, connecting rods, gears, and handles are symmetrical about the longitudinal axis of the fixing frame and are respectively positioned on the support legs without sliding grooves. This design, through the symmetrical arrangement of all adjusting elements, effectively improves the accuracy and reliability of adjustment, enhances the stability and balance of the overall structure, and simplifies the operation process, allowing users to adjust conveniently and efficiently.
[0013] Furthermore, a locking device is provided on the side of the support leg. The locking device includes a sliding shell, one end of which is fixedly connected to the side of the support leg. A sliding rod is slidably connected to the inner side of the sliding shell, and a retaining sleeve is fixedly connected to one end of the sliding rod. An arc-shaped groove is formed on the side of the retaining sleeve. This locking device allows the angle or height of the roller to be finely adjusted according to actual usage requirements, and it can be locked in the desired position after adjustment, increasing the flexibility and adaptability of the equipment.
[0014] Furthermore, a return spring is fixedly connected to the side of the support leg, with one end of the return spring fixedly connected to the side of the sleeve. The side of the handle is located on the displacement trajectory of the sleeve. The core function of this design is to enhance the locking effect and ease of operation of the sleeve, allowing the handle to lock quickly and stably after adjustment, thereby improving the overall user experience and safety of the system.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model achieves vertical movement through the interplay of components such as gears, racks, and shafts. When the operator turns the handle, the handle drives the shaft to rotate, which in turn drives the gears. The gears, in turn, drive the meshing rack to move vertically. This vertical movement of the rack drives the connecting rod to move vertically, which in turn drives the connecting column to move vertically. This vertical movement of the connecting column then drives one end of the fixed frame to move vertically, which in turn drives the roller to move vertically. This allows for precise adjustment of the roller's angle, enabling an adjustable roller to adapt to different processing, conveying, and winding requirements.
[0017] 2. This utility model utilizes a telescopic rod, a retaining sleeve, and other components that work together to achieve the following: When the roller angle needs adjustment, the operator rotates the handle. This rotation, through the arc-shaped groove, pushes the retaining sleeve horizontally. The horizontal movement of the retaining sleeve then pushes the sliding rod in a horizontal retraction motion within the sliding housing. Upon completion of the adjustment, the return spring, through its own elasticity, pushes the retaining sleeve to its horizontal reset position. This reset motion of the retaining sleeve, in turn, causes the sliding rod to return to its original position. Thus, this locking device allows for fine-tuning of the roller angle or height according to actual usage requirements, and after adjustment, it can be locked in the desired position, increasing the flexibility and adaptability of the equipment.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
