[0002] A paper reel is a device component used to collect and reel paper. It is widely used in the papermaking, printing, packaging and other industries. Its main function is to reel up the paper on the production line in an orderly manner for subsequent storage, transportation and further processing. For example, in a paper mill, after the paper is produced from the paper machine, it is rolled into a large paper roll by a paper reel, which can efficiently handle a large amount of paper.
[0003] Conventional tensioning barrels often use fluid tensioning. The advantage of fluid tensioning is that it is also very efficient, but the cost is high and it is prone to leakage, causing pollution to the workplace. Therefore, it is necessary to develop a new tensioning system that can maintain the original tensioning efficiency and avoid the defects of existing fluid tensioning. Summary of the invention

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. Using the principle that spheres automatically fill the space, the solid particle tensioning mechanism is an application based on the sphere filling theory. It aims to achieve effective tensioning of solid particles through the close arrangement of spheres to achieve the maximum space filling efficiency.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] Embodiment 1
[0024] As shown in the figure, a solid small particle medium tensioning and collecting cylinder described in the present invention includes a tensioning cylinder 1, a pressure-bearing panel 2, a telescopic tensioning slider 3, a reset spring 21, a blind screw 22, solid particles 4, a tensioning handle 5, a locking nut 51, a driving shaft 6 and an end cover 7. The tensioning cylinder 1 is a circular tubular structure, and the end cover 7 and the driving shaft 6 are respectively arranged at both ends of the tensioning cylinder 1. The tensioning cylinder 1 is provided with a plurality of yielding slots adapted to the telescopic tensioning slider on its body. The pressure-bearing panel 2 is multiple and corresponds to the yielding slots one by one. The pressure-bearing panel 2 is evenly arranged inside the tensioning cylinder 1 through the reset spring 21 and the blind screw 22, and each pressure-bearing panel is provided with a telescopic tensioning slider 3. The telescopic tensioning slider 3 is placed The tensioning handle 5 is placed in the corresponding position of the yielding slot, and a tensioning rod 52 is provided on the side of the tensioning tube. The tensioning rod 52 is a threaded rod, and the locking nut 51 is threadedly connected to the tensioning rod 52. A threaded hole is provided in the middle of the end cover 7, and the tensioning rod 52 is installed on the tensioning tube 1 through the threaded hole. The solid particles are filled in the tensioning tube. When the locking nut on the tensioning handle is loosened and the tensioning handle is screwed in, the solid small particle medium in the tensioning tube will be squeezed. As the tensioning rod is screwed in, the solid small particle medium is not compressed or the compressible space is extremely small. At this time, the small ball close to the pressure panel has a cumulative pressure greater than the existing pressure on the telescopic tensioning slider, and the telescopic tensioning slider extends outward to achieve the tensioning effect. On the contrary, when the locking nut on the tensioning handle is loosened and the tensioning handle is screwed out, the small solid particle medium in the tensioning cylinder will be subjected to gradually reduced extrusion pressure. As the tensioning rod is screwed out, the small ball close to the pressure panel has a cumulative pressure less than the existing pressure on the telescopic tensioning slider, and the telescopic tensioning slider cup is gradually compressed. At the same time, when the external pressure is insufficient and the telescopic tensioning slider cannot effectively recover, the designed reset spring will further contract the telescopic tensioning slider to fully reset it.
[0025] Furthermore, the driving shaft is fixed on the tensioning cylinder through a connecting plate and a fastening screw.
[0026] Furthermore, the pressure-bearing panel 2 is an arc-shaped plate, and the telescopic tensioning slider is fixed by fastening screws.
[0027] Furthermore, the telescopic tensioning slider 3 is also provided with a plurality of guide bosses 31 for guiding, and the yielding slot is provided with guide grooves corresponding to the guide bosses.
[0028] Furthermore, when the return spring is not acted upon by other external forces, the outer surface of the tensioning cylinder outside the telescopic tensioning slider is flush with or extended.
[0029] Embodiment 2
[0030] Furthermore, the tension rod 52 is also provided with an extension section 53 , which is a conical structure, and the conical structure is inserted into the solid particles.
[0031] In summary, the solid small particle medium tensioning and collecting cylinder described in the present invention utilizes the principle of spheres automatically filling the space to make a solid particle tensioning mechanism. This is an application based on the sphere filling theory, and is intended to achieve effective tensioning of solid particles through the close arrangement of spheres. The application of this principle involves the space filling problem in physics, that is, how to fill a three-dimensional space with a minimum number of spheres to achieve maximum space utilization. Through this principle, an efficient solid particle tensioning mechanism can be designed for various application scenarios that require close stacking and fixing of particles. When the locking nut on the tensioning handle is loosened and the tensioning handle is screwed in, the solid small particle medium in the tensioning cylinder will be squeezed. As the tensioning rod is screwed in, the solid small particle medium is not compressed or the compressible space is extremely small. At this time, the small ball close to the pressure panel has a cumulative pressure greater than the existing pressure on the telescopic tensioning slider, and the telescopic tensioning slider extends outward to achieve a tensioning effect. On the contrary, when the locking nut on the tensioning handle is loosened and the tensioning handle is screwed out, the small solid particle medium in the tensioning cylinder will be subjected to gradually reduced extrusion pressure. As the tensioning rod is screwed out, the small ball close to the pressure panel has a cumulative pressure less than the existing pressure on the telescopic tensioning slider, and the telescopic tensioning slider cup is gradually compressed. At the same time, when the external pressure is insufficient and the telescopic tensioning slider cannot effectively recover, the designed reset spring will further contract the telescopic tensioning slider to fully reset it.
