Description
Technical Field
[0001] The utility model relates to the technical field of flexible material manufacturing, and particularly relates to a planar tension partition traction machine. Background Art
[0002] At present, there are mainly two conventional tension partition methods on the market. The first is to realize tension partition by pressing a rubber roller against a traction roller, but this method is easy to damage the surface of the material. The second is to process the traction roller into a honeycomb shape and realize tension partition by evacuating the inside of the traction roller and adsorbing the material with a large wrap angle. However, for occasions where the wrap angle is relatively small, the adsorption effect of this method is poor and seriously affects the tension barrier effect. Therefore, there is an urgent need to propose a tension barrier mechanism that does not damage the surface of the material and is suitable for small wrap angle occasions. Content of the Utility Model

[0023] In order to better understand the technical means of the present utility model and be able to implement it according to the content of the specification, the following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.
[0024] See Figures 1-3 , this specific embodiment discloses a planar tension partition traction machine, including: a support frame 1, a power assembly 2 is fixedly connected to the support frame 1, the power assembly 2 is power-connected to a traction main roller 3, a traction idler roller 4 is arranged on one side of the traction main roller 3, a common transition roller 5 is arranged below the traction main roller 3 and the traction idler roller 4, a perforated belt 6 is sleeved on the traction main roller 3, the traction idler roller 4 and the common transition roller 5, a flat negative pressure chamber 7 is arranged below the perforated belt 6, and the flat negative pressure chamber 7 includes a silica gel skin 71, a perforated tray 72, and a perforated backing plate 73 which are arranged in sequence from bottom to top.
[0025] More specifically, honeycomb-shaped small holes are formed on the perforated belt 6, the perforated tray 72, and the perforated backing plate 73.
[0026] More specifically, see Figure 3 , the traction main roller 3, the traction idler roller 4, and the common transition roller 5 are arranged in a triangular shape.
[0027] In this specific embodiment, the ends of the traction main roller 3, the traction idler roller 4, and the common transition roller 5 are fixed to the support frame 1 by bearings to achieve smooth rotation of the traction main roller 3, the traction idler roller 4, and the common transition roller 5.
[0028] More specifically, the shape of the silica gel skin 71 is an annular rectangle, the shape of the perforated tray 72 is a first rectangle, the shape of the perforated backing plate 73 is a second rectangle, the length of the first rectangle is greater than the outer length of the annular rectangle, and the length of the first rectangle is greater than the length of the second rectangle. The widths of the first rectangle, the second rectangle, and the outer width of the annular rectangle are the same.
[0029] More specifically, the side part of the support frame 1 is two vertically arranged vertical plates 11 facing each other. Two horizontal support plates 12 are fixedly arranged at the tops of the two vertical plates 11. A support seat 13 is horizontally spanned at the end of each of the two horizontal support plates 12. The silica gel skin 71 is placed on the surfaces of the two horizontal support plates 12. The perforated tray 72 is placed on the surfaces of the silica gel skin 71 and the support seat 13, and the two end parts of the perforated tray 72 are fixedly arranged on the support seat 13.
[0030] In this specific embodiment, the support seat 13 horizontally spanned at the end of the two horizontal support plates 12, on the one hand, since the annular silica gel skin 71 has a certain thickness and the length of the perforated tray 72 is greater than the outer length of the annular silica gel skin 71, after the perforated tray 72 is placed on the surface of the annular silica gel skin 71, it prevents the end part from being suspended and causing gas leakage; on the other hand, the two end parts of the perforated tray 72 are fixedly arranged on the support seat 13, and the perforated tray 72 is fixed to avoid the movement of the perforated tray 72, thereby ensuring the stability of the vacuum adsorption effect.
[0031] In addition, the length of the first rectangle is greater than the outer length of the annular rectangle, and the length of the first rectangle is greater than the length of the second rectangle. Considering the structural stability of the flat negative pressure chamber, the perforated support plate 72 is extended, and the extended end portion is fixed on the support seat 13. This setting method actually increases the adsorption area, and can make the vacuum adsorption areas of the annular silicone skin 71, the perforated support plate 72, and the perforated pad 73 consistent, and are not affected by the fixed part of the end of the perforated support plate 72, and the vacuum adsorption effect is good.
[0032] More specifically, the flat negative pressure chamber 7 is connected to the blower 8 through a pipeline, and a pressure gauge seat 9 is provided on the support frame 1, and a pressure gauge (not shown in the figure) is provided on the pressure gauge seat. The pressure gauge can intuitively reflect the size of the vacuum adsorption pressure, thereby improving the human-computer interaction performance.
[0033] More specifically, the perforated belt 6 is a closed triangular belt with a width of more than 1700 mm. The blower 8 is used to evacuate the vacuum chamber so that the honeycomb holes on the belt absorb the material. The area of the absorbed material is larger, and the tension isolation effect is better. It is particularly suitable for occasions where the material wrap angle is relatively small.
[0034] More specifically, the power assembly 2 includes a driving motor 21 and a speed reducer 22 connected to the driving motor.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
