Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples.

In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0026] In some embodiments of the present application, a face paper conveying device is provided for use in a facing process in corrugated cardboard processing. Figure 1 This is a structural diagram of a facial tissue conveying device. Figure 2 This is a structural diagram of the tissue paper conveying device after omitting the first conveying belt 210. Figure 5 This is a structural diagram of the facial paper conveying device viewed from the bottom side.

[0027] The tissue paper conveying device includes a frame 100. The frame 100 is fixed on the ground and serves as a mounting carrier for other components. The frame 100 extends in a long strip shape.

[0028] The tissue paper conveying device further includes a first conveying belt 210. The first conveying belt 210 is arranged on the frame 100. The first conveying belt 210 moves under the action of the driving mechanism.

[0029] The tissue paper conveying device further includes a second conveyor belt 220. The second conveyor belt 220 is arranged on the frame 100. The second conveyor belt 220 moves under the action of the driving mechanism.

[0030] The first conveyor belt 210 and the second conveyor belt 220 move independently of each other and are driven by independent drive mechanisms. A tensioning pulley assembly is provided on the frame 100 for tensioning the first conveyor belt 210 and the second conveyor belt 220. The tensioning pulley assembly can be described in detail in the prior art and will not be further described in this embodiment.

[0031] The first conveyor belt 210 and the second conveyor belt 220 are arranged in sequence along the extension direction of the frame 100. The first conveyor belt 210 and the second conveyor belt 220 have the same movement direction. The facial paper is conveyed along the first conveyor belt 210 and the second conveyor belt 220 in sequence.

[0032] The paper conveying device further includes a front gauge assembly 710, a side gauge assembly 720 and a swinging paper guide roller assembly 740. The front gauge assembly 710, the side gauge assembly 720 and the swinging paper guide roller assembly 740 are all arranged on the frame 100 and located between the first conveyor belt 210 and the second conveyor belt 220.

[0033] The facial papers are conveyed in a staggered state on the first conveyor belt 210. That is, the facial papers on the first conveyor belt 210 overlap with each other, and there is an overlapping distance between two adjacent facial papers.

[0034] The facial tissue paper is transported in a single sheet on the second conveyor belt 220. In other words, the facial tissue paper on the second conveyor belt 220 is transported in a single sheet so as to be adhered to the corrugated paper downstream.

[0035] When the facial paper moves from the first conveyor belt 210 to the second conveyor belt 220, when the first piece of facial paper reaches the front rule assembly 710, it is blocked by the front rule assembly 710 and pauses for a moment, and then the side pull rule assembly 720 pulls the facial paper to the position of the side pull rule, and then the swing paper guide wheel assembly 740 falls, quickly starting the facial paper and conveying it to the second conveyor belt 220.

[0036] The second conveyor belt 220 has a higher speed than the first conveyor belt 210 . Due to the speed difference between the two conveyor belts, the stacked tissues on the first conveyor belt 210 can be transported individually on the second conveyor belt 220 .

[0037] The facial tissue conveyor also includes a deflection correction assembly 730, which is located at the end of the second conveyor belt 220. The facial tissue delivered from the second conveyor belt 220 is first adjusted by the deflection correction assembly 730 before being bonded to the corrugated paper, improving the bonding accuracy between the facial tissue and corrugated paper.

[0038] The front gauge assembly 710, the side pull gauge assembly 720, the swinging paper guide wheel assembly 740 and the correction assembly 730 are not improvements of the present application, and they all belong to conventional technical means in this field, so the specific structures of these three components are not described in detail in this embodiment.

[0039] In the related art paper conveying device, referring to Figure 8 Above the conveyor belt 10, there are a pressure roller 20 and at least two sets of movable pressure rollers 30. The pressure rollers 20 and the movable pressure rollers 30 apply pressure to the tissue paper on the conveyor belt 10, so that the tissue paper is conveyed forward along the conveyor belt 10. However, this system has the following disadvantages: a complex structure; the position of the movable pressure rollers 30 must be adjusted to accommodate the length of the cardboard each time a sheet is changed, which is cumbersome and reduces production efficiency; and the pressure rollers wear out after long-term use and need to be replaced, which is costly.

[0040] In order to solve this technical problem, the facial paper conveying device of the present application eliminates the pressure wheel 20 and the movable pressure wheel group 30, and adopts a suction method to adsorb the facial paper on the conveyor belt, thereby realizing negative pressure conveying of facial paper. It has a simple structure and low cost, and there is no need to adjust the pressure wheel position when changing orders, thereby improving production efficiency.

[0041] Specifically, refer to Figure 1The first conveyor belt 210 is provided with a plurality of first vent holes 211 , and the second conveyor belt 220 is provided with a plurality of second vent holes 221 .

[0042] The tissue paper conveying device also includes a suction assembly. A first suction hole is provided on the side of the suction assembly facing the first conveyor belt 210, and the first suction hole is connected to the first ventilation hole 211. A second suction hole is provided on the side of the suction assembly facing the second conveyor belt 220, and the second suction hole is connected to the second ventilation hole 221.

[0043] The suction assembly is configured to form a first negative pressure lower than the ambient pressure at the first ventilation hole through the air suction device, so that the facial paper is adsorbed on the first conveyor belt 210.

[0044] The suction assembly is further configured to form a second negative pressure lower than the ambient pressure at the second ventilation hole through the air suction device, so that the facial paper is adsorbed on the second conveyor belt 220.

[0045] The facial tissue conveyor uses ventilation holes in the conveyor belt. The suction assembly works in conjunction with the holes to create a negative pressure below ambient pressure at the holes, which in turn draws the tissue paper onto the conveyor belt. This eliminates the need for multiple rows of pressure rollers and a movable pressure roller assembly required in existing technologies, achieving negative pressure conveyance of tissue paper. This eliminates the need to adjust the pressure roller position each time a sheet is changed, improving production efficiency.

[0046] In some embodiments of the present application, the first negative pressure is greater than the second negative pressure. This is because the facial paper is conveyed in a staggered state on the first conveyor belt 210 and conveyed in a single sheet on the second conveyor belt 220, and the facial paper needs to be adjusted in position by the deflection correction assembly 730 as it passes through the second conveyor belt 220. Therefore, the magnitude of the second negative pressure should be consistent to ensure that the facial paper is attracted to the second conveyor belt 220 and that the position of the facial paper can be adjusted as it passes through the deflection correction assembly 730, thereby preventing the deflection correction assembly 730 from being unable to adjust the position of the facial paper due to excessive negative pressure.

[0047] In some embodiments of the present application, openings are provided on the frame 100 , and the first conveyor belt 210 and the second conveyor belt 220 correspond to the corresponding openings.

[0048] Reference Figure 5 The air suction component includes an air suction box 310. Figure 6 FIG. 3 is a structural diagram of the air suction box 310. The air suction box 310 is arranged on the frame 100, and the air suction box 310 is exposed from the opening. Figure 2 The suction box 310 is provided with suction holes 314. The suction hole on the suction box 310 facing the first conveyor belt 210 is the first suction hole, and the suction hole on the suction box 310 facing the second conveyor belt 220 is the second suction hole. The conveyor belts are attached to the suction box 310.

[0049] The air suction assembly further includes an air suction pipeline 320 , which is disposed on the frame 100 , and connects the air suction box 310 to the exhaust device.

[0050] Specifically, the suction box 310, suction duct 320, and exhaust device comprise the suction assembly, with the exhaust device providing the suction power. The suction box 310 is fixed to the frame 100, and the suction box 310 and suction duct 320 function as a ventilation channel. The suction box 310 is positioned at an opening in the frame 100, allowing the suction holes 314 on the suction box 310 to communicate with the corresponding vent holes on the conveyor belt. The suction box 310 also supports the conveyor belt, resulting in a compact structure.

[0051] In some embodiments of the present application, the frame 100 is provided with a first opening, and the first conveyor belt 210 corresponds to the first opening. The frame 100 is provided with a second opening, and the second conveyor belt 220 corresponds to the second opening.

[0052] The suction assembly includes a first suction assembly 410, which includes a plurality of first suction boxes 411. The plurality of first suction boxes 411 are disposed on the frame 100. The plurality of first suction boxes 411 are sequentially arranged along the conveying direction of the first conveyor belt 210. The first suction boxes 411 are exposed from a first opening. The first suction boxes 411 are provided with first suction holes on the side facing the first conveyor belt 210.

[0053] The first adsorption assembly further includes a first suction duct 412, which is disposed on the frame 100. The first suction duct 412 connects the first suction box 411 to the first exhaust device.

[0054] The suction assembly includes a second suction assembly 420, which includes a plurality of second suction boxes 421. The second suction boxes 421 are disposed on the frame 100. The plurality of second suction boxes 421 are arranged sequentially along the conveying direction of the second conveyor belt 220, and the second suction boxes 421 are exposed from the second opening. The second suction boxes 421 are provided with second suction holes on the side facing the second conveyor belt 220.

[0055] The second adsorption assembly further includes a second air suction duct 422 , which is disposed on the rack 100 . The second air suction duct 422 connects the second air suction box 421 with the second air exhaust device.

[0056] In other words, the suction assembly is divided into two parts: a first suction assembly 410 and a second suction assembly 420. The first suction assembly 410 is used to absorb facial tissue onto the first conveyor belt 210, while the second suction assembly 420 is used to absorb facial tissue onto the second conveyor belt 220. The first suction assembly 410 and the second suction assembly 420 are independent of each other, so that the suction pressure on different conveyor belts can be adjusted to meet different facial tissue conveying requirements.

[0057] The first suction assembly 410 and the second suction assembly 420 have the same structural principles and both include a suction box 310, a suction pipeline 320 and an exhaust device.

[0058] In some embodiments of the present application, ventilation holes are respectively provided on two opposite sides of the first conveyor belt 210 and two opposite sides of the second conveyor belt 220. That is, first ventilation holes 211 are provided on two opposite sides of the first conveyor belt 210, and second ventilation holes 221 are provided on two opposite sides of the second conveyor belt 220.

[0059] Reference Figure 6 and Figure 7 The suction box 310 is provided with ventilation openings 313 on two opposite sides of the side facing the conveyor belt. The suction box 310 is provided with a first support plate 311 and a second support plate 312 on the side facing the conveyor belt. The first support plate 311 is located between the ventilation openings 313 on both sides, and the second support plate 312 covers the ventilation openings 313. The second support plate 312 is provided with suction holes 314, which are connected to the ventilation openings 313. The conveyor belt is in contact with the first support plate 311 and the second support plate 312.

[0060] A first support plate 311 and a second support plate 312 are provided on the surface of the suction box 310, and a slightly concave structure is formed between the first support plate 311 and the second support plate 312. In this way, when the conveyor belt is pressed against the surface of the suction box 310 under the action of negative pressure, the conveyor belt is pressed against the first support plate 311 and the second support plate 312. The first support plate 311 and the second support plate 312 support the conveyor belt. At the same time, the gap between the first support plate 311 and the second support plate 312 can also prevent the conveyor belt from pressing against the entire surface of the suction box 310 and increasing friction.

[0061] Multiple vents 313 are provided, arranged in sequence along the length of the suction box 310, and are located on opposite sides of the suction box 310. Providing ventilation holes on opposite sides of the conveyor belt helps improve the reliability and smoothness of the tissue paper's adhesion to the conveyor belt.

[0062] In some embodiments of the present application, connecting ports 315 are respectively provided on the opposite side walls of the suction box 310, and the connecting ports 315 are connected to the suction pipeline 320 through a connecting pipe to achieve air conduction between the suction box 310 and the suction pipeline 320. Figure 3 The connecting pipe is omitted.

[0063] The connecting pipe is a hose. When the tissue paper conveying device is assembled, the suction box 310 and the suction pipe 320 are first fixed to the frame 100, and then the suction box 310 and the suction pipe 320 are connected through the hose.

[0064] In some embodiments of this application, refer to Figure 1 The frame 100 includes a horizontal frame section 110 and an inclined frame section 120. The inclined frame section 120 extends obliquely downward from the horizontal frame section 110. The second conveyor belt 220 is provided on the inclined frame section 120.

[0065] The first conveyor belt 210 includes a first horizontal conveying section 212 and a first inclined conveying section 213 . The first horizontal conveying section 212 is disposed on the horizontal frame section 110 , and the first inclined conveying section 213 is disposed on the inclined frame section 120 .

[0066] The swinging paper guide roller assembly 740 is disposed between the first inclined conveying section 213 and the second conveyor belt 220 . The swinging paper guide roller assembly 740 is configured to convey the surface paper on the first inclined conveying section 213 to the second conveyor belt 220 .

[0067] In some embodiments of this application, refer to Figure 1 The facial paper conveying device further includes a pressing wheel 500, which acts on the facial paper between the first horizontal conveying section 212 and the first inclined conveying section 213. The pressing wheel 500 bends the facial paper at an angle, so that the facial paper is conveyed from horizontal to obliquely downward.

[0068] Reference Figure 3 The frame 100 is provided with two first wide-band wheels 130, one of which is located at the end of the horizontal frame section 110, and the other is located at the starting end of the inclined frame section 120. The pressure roller 500 is located between the two first wide-band wheels 130. The two first wide-band wheels 130 support the bending position of the first conveyor belt 210.

[0069] In some embodiments of this application, refer to Figure 2 and Figure 4 The facial paper conveying device also includes a universal wheel 600, which acts on the facial paper located at the end of the first inclined conveying section 213.

[0070] One of the functions of the universal wheel 600 is to provide power to the facial paper, because the facial paper is conveyed in an overlapping manner on the first conveyor belt 210, and the overlap between two adjacent facial papers has a first distance, and there is a second distance between the end of the first conveyor belt 210 and the front rule assembly 710. The second distance is greater than the first distance. Therefore, the suction assembly does not provide power before a part of the facial paper reaches the front rule assembly 710. At this time, the universal wheel 600 is used to press the end of the conveyor belt to provide power.

[0071] The second function of the universal wheel 600 is that when the facial paper reaches the front gauge assembly 710, the side pull gauge assembly 720 is needed to pull the facial paper to the position of the side pull gauge assembly 720. The universal wheel 600 is used to press the facial paper to ensure its stability.

[0072] The third function of the universal wheel 600 is that the facial paper needs to move forward and sideways, so the pressing wheel 500 here is required to have the function of rotating forward and backward and left and right, so the pressing wheel 500 used is the universal wheel 600.

[0073] Reference Figure 4 A second wide-band wheel 140 is provided on the frame 100, and the universal wheel 600 acts on the second wide-band wheel 140. When the facial paper is under pressure, both sides of the facial paper are subjected to rolling force to avoid tearing the facial paper.

[0074] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0075] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
