Technical Field

[0001] This utility model belongs to the field of tobacco production and conveying technology, and specifically relates to an adjustable height support roller. Background Technology

[0002] The support roller shaft in a tobacco company workshop is the internal hub of the support roller, playing a vital role in transmitting bearing loads and enabling the roller body to rotate and move. As an important component in a tobacco company workshop, the performance and quality of the support roller shaft directly affect the stability and reliability of the entire production line. In existing use, the support roller shaft is generally directly fixed inside the frame. When it is necessary to adjust the height of the support roller shaft according to the specifications of the materials and the work requirements, this connection method of the support roller shaft cannot be conveniently adjusted, which leads to limitations in its use. Therefore, we propose a support roller shaft with adjustable height. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3This utility model provides a technical solution: an adjustable height support roller, including a frame 1, a roller 2 arranged inside the frame 1, roller shafts 3 fixedly connected to both sides of the roller 2, a height adjustment mechanism connected to the roller shafts 3 arranged inside the frame 1, and a wear-resistant protective mechanism sleeved on the surface of the roller 2. The height adjustment mechanism includes a connecting guide component and an adjustment component.

[0020] In this embodiment, preferably, the connecting guide assembly includes connecting blocks 100 symmetrically fixed on both sides of the roller shaft 3 and connecting grooves 101 extending through both ends of the connecting blocks 100. Connecting rods 102 are symmetrically fixed on both sides of the interior of the frame 1. The connecting rods 102 are slidably connected to the connecting grooves 101, and play a directional guiding role when the roller shaft 3 rises and falls.

[0021] In this embodiment, preferably, a guide groove 200 extending vertically is formed through the surface of the connecting rod 102. A guide block 201 is disposed inside the connecting groove 102. The guide block 201 engages with the guide groove 200 to restrict the connecting block 100 from moving vertically along the guide groove 200. The guide block 201 can be integrally formed with the connecting block 100.

[0022] In this embodiment, preferably, the adjustment component includes: a push plate 300 horizontally disposed at the bottom end of the roller 2, and push blocks 301 symmetrically fixed at both ends of the push plate 300 and fixedly connected to the bottom end of the roller 3, which enables the adjustment component to be connected to the roller 3.

[0023] In this embodiment, preferably, a screw hole 400 is provided through the bottom end of the frame 1, and an adjusting threaded rod 401 is provided at the bottom end of the frame 1 to be screwed into the screw hole 400. A bearing 402 is connected between the top end of the adjusting threaded rod 401 and the push plate 300 to facilitate raising or lowering the roller 2 and the roller shaft 3.

[0024] In this embodiment, preferably, the bottom end of the frame 1 is provided with an operating wheel 500 that is fixed to the bottom end of the adjusting threaded rod 401. The bottom end of the operating wheel 500 is fixed with a crank handle, which can easily rotate the adjusting threaded rod 401.

[0025] In this embodiment, preferably, the wear-resistant protection mechanism includes a wear-resistant protective layer 600 sleeved on the surface of the roller 2, which can enhance the wear resistance of the roller 2 surface.

[0026] The working principle and usage of this utility model are as follows: When the height of roller 2 and roller shaft 3 needs to be adjusted upwards, the operating wheel 500 is manually rotated, causing the adjusting threaded rod 401 to rotate upwards inside the threaded hole 400. Simultaneously, the bearing 402 pushes the push plate 300 upwards inside the frame 1, and the push block 301 pushes the roller shaft 3 upwards to adjust the height. While the roller shaft 3 moves, the connecting blocks 100 on both sides of the roller shaft 3 slide on the surface of the connecting rod 102 through the connecting groove 101, and drive the guide block 201 to move inside the guide groove 200, providing a guiding function. Once the roller shaft 3 and roller 2 are adjusted to a suitable height inside the frame 1, the operating wheel 500 is stopped, thus positioning the height of roller 2 and roller shaft 3 and completing the adjustment. Furthermore, the wear-resistant protective layer 600 provides wear resistance and protection during the rotation of roller 2.

[0027] When it is necessary to adjust the height of roller 2 and roller shaft 3 downwards, simply rotate the operating wheel 500 in the opposite direction.

[0028] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
