[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Reference Figures 1-11 This embodiment is a single-sheet forming tube suction traction device, including a frame component 100, a transmission component 200, a suction component 300, an edge-rubbing component 400, and a traction component 500. The frame component 100 includes two mounting plates 101 connected by multiple square supports 102. The transmission component 200 includes a transmission assembly 201 disposed on one side of the mounting plates 101. Two second guide rollers 202 are rotatably disposed on one side of the two mounting plates 101. One end of each of the two second guide rollers 202 passes through the mounting plate 101 and is provided with a first traction gear 202a and a second traction gear 202b. A power assembly 203 for driving the transmission assembly 201, the first traction gear 202a, and the second traction gear 202b to rotate is disposed on one side of the mounting plate 101 located on the transmission assembly 201. Belt rollers 20 are rotatably disposed on the other side of the two mounting plates 101. 4 and the third guide roller 204a, the suction component 300 includes a suction box 301 placed at the top of the square support 102, the edge rubbing component 400 includes an edge rubbing adjustment wall plate 401 respectively disposed on the outer wall of the middle part of the two mounting plates 101, an edge rubbing assembly 402 is disposed on the edge adjustment wall plate 401, a support frame 403 is disposed above the suction box 301, a conveyor belt 209 is disposed between the suction box 301 and the support frame 403, a plurality of through holes 209a are evenly distributed on the surface of the conveyor belt 209, the conveyor belt 209 is wound between the two second guide rollers 202, the belt roller 204 and the third guide roller 204a, the traction component 500 includes a traction wheel shaft 501 rotatably disposed between the two mounting plates 101, one end of the traction wheel shaft 501 passes through the mounting plate 101 and is provided with a large traction gear 502 that meshes with the second traction gear 202b, and two traction wheels 503 are disposed at intervals on the outer wall of the traction wheel shaft 501.

[0029] A single sheet of paper is bent and pasted end to end around the support frame 403 to form a paper tube 1. The power component 203 is turned on, and the power component 203 drives the transmission component 201, the first traction gear 202a and the second traction gear 202b to rotate. Therefore, the two second guide rollers 202 also start to rotate, which in turn drives the conveyor belt 209 to rotate. The suction box 301 is connected to an external negative pressure device (existing equipment, such as an air pump), so that the suction box 301 generates suction on the conveyor belt 209, which causes the paper tube 1 to be attracted to the conveyor belt 209 and move with the conveyor belt 209. The paper tube 1 is folded into shape by the edge rubbing component 402.

[0030] In this embodiment, the mounting plate 101 includes an edge-rubbing wall plate 101a and a lower wall plate 101b arranged vertically. The two sides of the edge-rubbing wall plate 101a and the lower wall plate 101b are respectively connected to a traction wall plate 101c and a suction wall plate 101d. The two traction wall plates 101c and the two suction wall plates 101d are connected by multiple round supports 103. The two edge-rubbing wall plates 101a are connected by multiple square supports 102. Multiple first guide rollers 104 are rotatably arranged between the two lower wall plates 101b. The traction wheel shaft 501 is rotatably arranged between the two traction wall plates 101c.

[0031] In this embodiment, the transmission assembly 201 includes two rotating shafts disposed on the traction wall plate 101c. The ends of the two rotating shafts are respectively rotatably provided with a first transition gear 201a and a second transition gear 201b that mesh with each other. The first transition gear 201a meshes with the first traction gear 202a and the second traction gear 202b respectively. The power assembly 203 includes a motor base 203a disposed on the traction wall plate 101c. The motor base 203a is provided with a servo motor 203b and a reducer 203c that are connected to each other. The output shaft end of the reducer 203c is provided with a drive gear 203d that meshes with the first transition gear 201a.

[0032] When the servo motor 203b is turned on, the servo motor 203b is reduced in speed by the reducer 203c and drives the drive gear 203d to rotate. The drive gear 203d drives the first transition gear 201a to rotate. Since the first transition gear 201a meshes with the first traction gear 202a and the second traction gear 202b, the first traction gear 202a and the second traction gear 202b are also driven to rotate, which in turn drives the two second guide rollers 202 to rotate. The two second guide rollers 202 drive the conveyor belt 209 to rotate.

[0033] In this embodiment, an air intake assembly 302 is provided below the air intake box 301. The air intake box 301 is an open hollow structure. The interior of the air intake box 301 is divided into three chambers 301a along the length direction by two partition plates. The bottom walls of the middle chamber 301a are respectively provided with first connecting holes 301b, and the bottom walls of the other two chambers 301a are respectively provided with second connecting holes 301c. The air intake assembly 302 includes two air intake pipes 302a and a central air intake pipe located between the two air intake pipes 302a. The air tube 302b and the two air inhalation tubes 302a are connected at one end to the first connecting hole 301b. The two sides of the tube wall of the middle air inhalation tube 302b are connected to two branch tubes 302c. The branch tubes 302c are connected to the second connecting hole 301c through flexible tubes. An air inhalation plate 301d is provided at the opening of the air inhalation box 301. The air inhalation plate 301d has multiple air inhalation holes 301e evenly distributed. The multiple air inhalation holes 301e have the same arrangement as the multiple through holes 209a on the surface of the conveyor belt 209.

[0034] One end of each of the two suction pipes 302a and the middle suction pipe 302b is connected to an external negative pressure device (existing equipment, such as an air pump). The external negative pressure device draws air from the three chambers 301a inside the suction box 301 through the two suction pipes 302a and the middle suction pipe 302b to generate negative pressure. Since the suction plate 301d at the top of the suction box 301 has multiple suction holes 301e evenly distributed, the suction box 301 can adsorb the conveyor belt 209 at the top of the suction plate 301d. The surface of the conveyor belt 209 has multiple through holes 209a evenly distributed, so the conveyor belt 209 can also adsorb the paper tube 1, so that the paper tube 1 moves with the conveyor belt 209.

[0035] In this embodiment, each of the two traction wall plates 101c has a sliding groove 101e on one side. The transmission component 200 also includes a slider 205 that is slidably engaged in the two sliding grooves 101e. A rotating shaft 205a is rotatably arranged between the two sliders 205. A belt tension roller 205b is provided on the outer wall of the rotating shaft 205a. A tensioning block 205c is provided at the opening of the sliding groove 101e. A first screw 205d is rotatably arranged on the side wall of the slider 205. The first screw 205d is threadedly connected to the tensioning block 205c. A fourth guide roller 206, a fifth guide roller 206a, and a sixth guide roller 206b are rotatably arranged between 01c. The fourth guide roller 206 and the fifth guide roller 206a are located on one side of the belt tension roller 205b, and the sixth guide roller 206b is located on the other side of the belt tension roller 205b. The conveyor belt 209 is sequentially wound around the surfaces of two second guide rollers 202, the sixth guide roller 206b, the fourth guide roller 206, the belt tension roller 205b, the fifth guide roller 206a, multiple first guide rollers 104, the third guide roller 204a, and the belt roller 204.

[0036] The first screw 205d on the side wall of the two rotatable sliders 205 can adjust the position of the two sliders 205 in the slide groove 101e. As the position of the two sliders 205 changes, the belt tensioning roller 205b between the two sliders 205 can adjust the tension of the conveyor belt 209.

[0037] In this embodiment, one end of the rotating shaft 205a passes through the slider 205 and is provided with a driven sprocket 205e. The center of the second transition gear 201b is provided with a driving sprocket 201c via a rotating shaft. A chain is provided between the driving sprocket 201c and the driven sprocket 205e. The traction wall plate 101c is located above one side of the driven sprocket 205e and is provided with a rotating rod 207 and a top block 208. A swing arm 207a is rotatably provided on the outer wall of the rotating rod 207. A tensioning sprocket 207b is rotatably provided at the end of the swing arm 207a. A top rod 208a is threadedly connected to the end face of the top block 208.

[0038] When the first transition gear 201a rotates, it drives the second transition gear 201b to rotate, which in turn drives the drive sprocket 201c at the center of the second transition gear 201b to rotate. The drive sprocket 201c drives the driven sprocket 205e to rotate via a chain. The driven sprocket 205e can drive the rotation of the rotating shaft 205a and the belt tension roller 205b. Therefore, when the belt tension roller 205b rotates, it can also drive the transmission belt 209 to move. The chain between the drive sprocket 201c and the driven sprocket 205e can be adjusted in tension. When the chain is relatively loose, the push rod 208a is rotated, causing the push rod 208a to push against the swing arm 207a and rotate around the rotating rod 207. This causes the tension sprocket 207b at the end of the rotating rod 207 to mesh with the chain and abut against the chain, thus making the chain tense.

[0039] In this embodiment, the edge-rubbing adjustment wall panel 401 is disposed on the outer wall of the edge-rubbing wall panel 101a. The edge-rubbing assembly 402 includes guide rods 402a slidably inserted into both sides of the edge-rubbing adjustment wall panel 401. The ends of the two guide rods 402a are connected to the fixing block 402b. The bottom end of the fixing block 402b is fixed to the top of the adjustment plate 402c. Multiple support rods 402d are fixed at equal intervals on the side wall of the adjustment plate 402c. An adjustment rod 402e is movably connected to the outer wall of the support rod 402d through a clamping member 404. A first bearing 402f is fixed to the end of the adjustment rod 402e. A rotating column is disposed inside the first bearing 402f. The bottom of the rotating column... The edge-rubbing wheels 402g are connected to the end. The diameter of the multiple edge-rubbing wheels 402g decreases sequentially in the direction away from the traction wheel 503, and the thickness of the multiple edge-rubbing wheels 402g increases sequentially in the direction away from the traction wheel 503. An adjustment block 402h is provided at the middle of the top of the adjustment plate 402c. A second bearing 402i is provided at the top of the edge-rubbing adjustment wall plate 401 at a position corresponding to the adjustment block 402h. A threaded rod 402j is provided inside the second bearing 402i. One end of the threaded rod 402j extends toward the adjustment block 402h and is threadedly connected to the adjustment block 402h. A handwheel 402k is provided at the other end of the threaded rod 402j.

[0040] Turning the handwheel 402k clockwise or counterclockwise will cause the threaded rod 402j to rotate clockwise or counterclockwise. The rotation of the threaded rod 402j can cause the adjusting plate 402c to move away from or closer to the edge-rubbing adjusting wall plate 401, thereby adjusting the distance between the multiple edge-rubbing wheels 402g and the edge-rubbing adjusting wall plate 401. The adjusting rod 402e can be set at different positions on the outer wall of the support rod 402d through the clamping member 404, thereby adjusting the height of the multiple edge-rubbing wheels 402g at the end of the adjusting rod 402e.

[0041] In this embodiment, the clamping member 404 has a cuboid structure. The front and rear end faces and the upper and lower end faces of the clamping member 404 are respectively provided with clamping holes 404a for clamping the support rod 402d and the adjusting rod 402e. The inner diameter of the clamping hole 404a is equal to the outer diameter of the support rod 402d and the adjusting rod 402e. A slit 404b communicating with the outside of the clamping member 404 is provided on one side of the clamping hole 404a. Corresponding threaded holes and through holes are respectively provided on the two side walls of the slit 404b.

[0042] The support rod 402d and the adjusting rod 402e can pass through the clamping hole 404a. After the positions of the support rod 402d and the adjusting rod 402e are determined, an external screw is inserted into the through hole and screwed into the threaded hole. Under the action of the screw, the gap 404b becomes smaller, which in turn drives the inner diameter of the clamping hole 404a to become smaller, thereby clamping the support rod 402d or the adjusting rod 402e, so that the positional relationship between the support rod 402d or the adjusting rod 402e and the clamping member 404 is fixed.

[0043] In this embodiment, the support frame 403 includes two lower templates 403a located on both sides above the conveyor belt 209. Upper templates 403b are respectively provided above the two lower templates 403a. The two upper templates 403b and the two lower templates 403a are connected by multiple connecting plates 403d. The upper and lower connecting plates 403d are connected by connecting blocks 403c. The ends of the two upper templates 403b away from the traction wheel 503 are respectively connected to a straight first guide plate 403e and an arc-shaped second guide plate 403f. The ends of the two lower templates 403a away from the traction wheel 503 extend outward.

[0044] The ends of the two lower templates 403a away from the traction wheel 503 extend outward and are fixed by an external device (not shown in the attached diagram of the instruction manual). A single sheet of paper is bent around the two lower templates 403a and pasted end to end to form a paper tube 1. After the paper tube 1 passes through the straight first guide plate 403e and the arc-shaped second guide plate 403f at the ends of the two upper templates 403b, the paper tube 1 is placed between the two lower templates 403a and the two upper templates 403b, which slowly expands the inside of the paper tube 1.

[0045] In this embodiment, mounting blocks 504 are respectively provided on the side walls of the two traction wall plates 101c. A tensioning guide wheel shaft 504a is provided between the two mounting blocks 504. Mounting brackets 504b are respectively provided on the outer wall of the tensioning guide wheel shaft 504a at positions corresponding to the two traction wheels 503. Two tensioning guide wheels 504c are rotatably mounted on the two mounting brackets 504b. Two guide wheel shafts 505 are rotatably mounted between the two traction wall plates 101c. Guide wheels 505a are respectively provided on the outer wall of the guide wheel shaft 505 at positions corresponding to the two traction wheels 503. A base belt 506 is wound between the traction wheels 503, the guide wheels 505a, and the tensioning guide wheels 504c.

[0046] Since the large traction gear 502 at the end of the traction wheel shaft 501 meshes with the second traction gear 202b, the rotation of the second traction gear 202b can drive the large traction gear 502 to rotate. Therefore, the traction wheel shaft 501 and the two traction wheels 503 will also be driven to rotate. Since the base belt 506 is located between the traction wheel 503, the guide wheel 505a, and the tension guide wheel 504c, the two traction wheels 503 drive the rotation of the guide wheel 505a and the tension guide wheel 504c through the base belt 506. When the side of the paper tube 1 is squeezed and folded by the edge rubbing assembly 402 and begins to leave the support frame 403, one end of the paper tube 1 begins to contact the rotating base belt 506. Under the drive of the base belt 506, the paper tube 1 is squeezed between the conveyor belt 209 and the base belt 506, so that the side of the paper tube 1 is squeezed and folded and then squeezed and compressed.

[0047] Working principle: When the paper, with its ends pasted into paper tube 1, passes the support frame 403, the servo motor 203b is reduced in speed by the reducer 203c and drives the drive gear 203d to rotate. The drive gear 203d drives the first transition gear 201a to rotate. Since the first transition gear 201a meshes with the first traction gear 202a and the second traction gear 202b, the first traction gear 202a and the second traction gear 202b are also driven to rotate, thereby driving the two second guide rollers 202 to rotate. When the first transition gear 201a rotates, it drives the second transition gear 201b to rotate, thereby driving the drive sprocket 201c at the center of the second transition gear 201b to rotate. The drive sprocket 201c drives the driven sprocket 205e to rotate via a chain. The driven sprocket 205e drives the rotation of the rotating shaft 205a and the belt tensioning roller 205b. Therefore, when the belt tensioning roller 205b and the two second guide rollers 202 rotate, they drive the conveyor belt 209 to rotate around the two second guide rollers 202, the sixth guide roller 206b, the fourth guide roller 206, the belt tensioning roller 205b, the fifth guide roller 206a, multiple first guide rollers 104, the third guide roller 204a, and the belt roller 204. One end of the two suction pipes 302a and the middle suction pipe 302b is connected to an external negative pressure device (existing equipment, such as an air pump). The external negative pressure device evacuates air from the three chambers 301a inside the suction box 301 through the two suction pipes 302a and the middle suction pipe 302b, creating a negative pressure inside. Because the suction plate 301d at the top of the suction box 301 has multiple suction holes 301e evenly distributed, the suction box 301 can adsorb the conveyor belt 209 at the top of the suction plate 301d. The conveyor belt 209 has multiple through holes 209a evenly distributed on its surface, so it can also adsorb the paper tube 1. As the paper tube 1 moves with the conveyor belt 209, after passing the straight first guide plate 403e and the arc-shaped second guide plate 403f at the ends of the two upper templates 403b, the paper tube 1 is placed between the two lower templates 403a and the two upper templates 403b, slowly expanding the interior of the paper tube 1. As the paper tube 1 moves forward with the conveyor belt 209, both sides of the paper tube 1 begin to be squeezed and folded by the edge-rubbing rollers 402g. Due to the multiple edge-rubbing rollers 402g... The diameter of the paper tube 1 decreases sequentially away from the traction wheel 503, while the thickness increases sequentially. Therefore, as the paper tube 1 moves forward, it is compressed on both sides by the edge-rubbing wheels 402g, which have increasingly larger diameters and increasingly smaller thicknesses. This prevents the paper tube 1 from breaking during compression and folding. Since the large traction gear 502 at the end of the traction wheel shaft 501 meshes with the second traction gear 202b, the rotation of the second traction gear 202b drives the large traction gear 502 to rotate. Therefore, the traction wheel shaft 501 and the two traction wheels 503 are also driven to rotate. Because the base belt 506 is positioned between the traction wheel 503, the guide wheel 505a, and the tensioning guide wheel 504c, the two traction wheels 503 drive the guide wheel 505a through the base belt 506.With the rotation of the tension guide roller 504c, when the side of the paper tube 1 is squeezed and folded by the edge-rubbing assembly 402 and begins to leave the support frame 403, one end of the paper tube 1 begins to contact the rotating base belt 506. Driven by the base belt 506, the paper tube 1 is squeezed between the conveyor belt 209 and the base belt 506, facilitating the transport of the paper tube 1 to the next process.
