Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a winding shaft structure of a slitting machine. Background Technique

[0002] In the packaging and printing industry, the final finished products often start from a roll of paper. When the roll paper is purchased by the manufacturer, it is usually a wide-width paper with a large length and width. Therefore, in actual production, printing enterprises often need to unwind, slit, and then wind the wide-width roll paper according to the specifications of the products to obtain a roll paper with a suitable width for subsequent production use.

[0003] When slitting narrow strips of thin film in the prior art, multiple narrow paper tubes are fixed by existing air-expanding slip shafts. Therefore, a winding shaft structure of a slitting machine is proposed here. Content of the Utility Model

[0004] Technical Problem to be Solved

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a winding shaft structure of a slitting machine.

[0006] Technical Solution

[0007] To achieve the above purpose, the utility model provides the following technical solution: A winding shaft structure of a slitting machine includes a winding shaft body, an airbag, a stainless steel sheet, a wool felt, a paper tube, and a mounting seat. A plurality of mounting grooves are opened inside the winding shaft body. The airbag is installed at the bottom of the mounting groove. A stainless steel sheet is arranged above the airbag. A wool felt is fixedly connected to the side of the stainless steel sheet away from the airbag. An air charging and discharging channel is arranged inside the winding shaft body, and the air charging and discharging channel is communicated with the airbag. In the application, when the airbag is inflated, it can push the stainless steel sheet. The wool felt is adhesively fixed on the stainless steel sheet and protrudes with the stainless steel sheet to tightly support the paper tube sleeved on the winding shaft body. When the airbag deflates, the stainless steel sheet retracts, and the wool felt retracts with the stainless steel sheet, so that the limit on the paper tube can be released. The difference between the utility model and the prior art is that the slip ring in the prior art is cancelled, and the paper tube is directly regarded as the slip ring, so that the paper tube directly rubs against the wool felt to generate tension, which is used to solve the clamping problem of the paper tube when slitting narrow strips. The design has a simple structure, good use effect, and strong practicability.

[0008] Preferably, a paper tube is sleeved outside the winding shaft body.

[0009] Preferably, a mounting seat is installed at one end of the winding shaft body. A bearing is installed inside the mounting seat. The winding shaft body is rotatably installed inside the mounting seat through the bearing.

[0010] Preferably, a driving gear is fixedly installed at one end of the rewinding shaft body.

[0011] Preferably, a sealed rotary air joint is connected to one end of the air charging and discharging channel.

[0012] Preferably, the number of the pairs of installation grooves is three, and the cross-sectional shape of the installation groove is "convex".

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 6 As shown, the present invention provides a technical solution: a rewinding shaft structure of a slitter, which includes a rewinding shaft body 1, an airbag 2, a stainless steel sheet 3, a wool felt 4, a paper tube 5 and a mounting seat 6. A plurality of mounting grooves 101 are opened inside the rewinding shaft body 1. The airbag 2 is installed at the bottom of the mounting groove 101. A stainless steel sheet 3 is arranged above the airbag 2. A wool felt 4 is fixedly connected to the side of the stainless steel sheet 3 away from the airbag 2. An inflation and deflation channel 102 is arranged inside the rewinding shaft body 1, and the inflation and deflation channel 102 is communicated with the airbag 2. When in use in this application, the airbag 2 is inflated to push the stainless steel sheet 3. The wool felt 4 is adhesively fixed on the stainless steel sheet and protrudes with the stainless steel sheet 3 to tightly support the paper tube 5 sleeved on the rewinding shaft body 1. When the airbag 2 deflates, the stainless steel sheet 3 retracts, and the wool felt 4 retracts with the stainless steel sheet 3, so that the limit on the paper tube 5 can be released. The difference between the present invention and the prior art is that the slip ring in the prior art is cancelled, and the paper tube is directly regarded as the slip ring, so that the paper tube directly rubs against the wool felt to generate tension, which is used to solve the clamping problem of the paper tube when slitting narrow strips. This design has a simple structure and good use effect, and has strong practicability.

[0027] Please refer specifically to Figure 1 、 Figure 2 and Figure 3 A paper tube 5 is sleeved outside the rewinding shaft body 1. One end of the rewinding shaft body 1 is provided with a mounting seat 6. A bearing 8 is installed inside the mounting seat 6. The rewinding shaft body 1 is rotatably installed inside the mounting seat 6 through the bearing 8, and a driving gear 9 is fixedly installed at one end of the rewinding shaft body 1.

[0028] Please refer specifically to Figure 2 and Figure 6, one end of the air charging and discharging channel 102 is connected with a sealed rotary joint 7, which is connected with an air pump and a pressure reducing valve. The air pump inflates the air charging and discharging channel 102 through the sealed rotary joint 7, so that the airbag 2 is filled with gas. The pressure reducing valve can discharge the high-pressure gas in the airbag 2 and the air charging and discharging channel 102 from the sealed rotary joint 7.

[0029] Please refer particularly to Figure 4 , the number of pairs of installation grooves 101 is three, and the cross-sectional shape of the installation groove 101 is "convex".

[0030] Working principle: When the airbag 2 is inflated, it pushes the stainless steel sheet 3. The wool felt 4 is adhesively fixed on the stainless steel sheet and protrudes with the stainless steel sheet 3, tightening the paper tube 5 sleeved on the winding shaft body 1. When the airbag 2 deflates, the stainless steel sheet 3 retracts, and the wool felt 4 retracts with the stainless steel sheet 3, thus releasing the limit on the paper tube 5.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
