A circular barrel body winding forming device

Abstract

This utility model relates to the field of paper tube processing technology and discloses a circular tube body winding and forming device, including a housing and a transmission base. A winding roller is rotatably connected to the top of the transmission base. A guide roller is rotatably connected to the top of the housing relative to the winding roller. A fixing plate is fixedly installed in the middle of the side of the housing opposite to the winding roller. A tensioning and anti-loosening component for clamping kraft paper for positioning is provided on the top of the fixing plate. A paper cutting component for cutting kraft paper is provided at the bottom of the fixing plate. By starting a servo motor to drive the rotating rod to rotate, the clamping roller will rotate relative to each other through the meshing gears on both sides, which will help pull the kraft paper downward. Moreover, after the kraft paper is cut, the ratchet's limiting action on the ratchet wheel can prevent the ratchet wheel from reversing, which in turn restricts the relative reversal of the clamping roller. Therefore, the kraft paper can always be kept taut, thereby preventing the kraft paper from being pulled back and loosening.

Description

Technical Field

[0001] This utility model relates to the field of paper tube processing technology, specifically a circular barrel body winding and forming device. Background Technology

[0002] Paper tubes are cylindrical structures made of paper and used as packaging containers. They are generally made of kraft paper, which enhances the structural strength of the paper tube. They can be processed into square or round paper tubes as needed. They are sturdy and waterproof, and are widely used in food, logistics, cultural products and other fields.

[0003] In the process of processing the cylindrical tube, kraft paper needs to be wound around the winding roller to form the shape. The existing winding forming device needs to cut the kraft paper after winding the cylindrical tube and then take out the wound tube. However, one end of the cut kraft paper is not restricted and will be pulled back, causing the kraft paper to be loose and not taut. This will affect the winding processing of the next tube. Therefore, further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a circular barrel winding forming device, comprising a housing and a transmission base. The housing contains a set of rotating rollers for tensioning kraft paper. A controller is mounted on the top of the transmission base. A winding roller is rotatably connected to the top of the transmission base, and an abutment roller for pressing against the kraft paper roll forming is also provided on the side of the winding roller. A guide roller is rotatably connected to the top of the housing relative to the winding roller. A fixing plate is fixedly installed in the middle of the side of the housing opposite the winding roller. A tensioning and anti-loosening component for clamping and positioning the kraft paper is provided on the top of the fixing plate. A paper cutting component for cutting the kraft paper is provided at the bottom of the fixing plate. The paper cutting component facilitates cutting the kraft paper, and the tensioning and anti-loosening component clamps and positions the kraft paper, preventing it from pulling back and loosening.

[0005] As an optimization, the tensioning and anti-loosening component includes a support fixedly installed on the top side of the fixed plate, a clamping roller is provided between the two supports, a rotating rod is fixedly installed in the center of the clamping roller, and the clamping roller is rotatably connected between the two supports through the rotating rod. A gear is fixedly installed on the outer side of one end of the rotating rod, and a servo motor for driving the rotating rod is fixedly installed on the outer side of the support. An anti-reverse component is provided inside the other support to limit the reverse rotation of the clamping roller. The anti-reverse component can prevent the clamping roller from reversing, thereby ensuring that the kraft paper is always tensioned.

[0006] As an optimization, the anti-reverse component includes a ratchet rotatably connected inside the support. Inside the support and on the side of the ratchet, there is a spring-loaded pawl. The pawl is engaged between adjacent teeth on the outside of the ratchet by the spring force. The pawl limits the ratchet by limiting the relative reversal of the clamping roller.

[0007] As an optimization, the pawl is hinged inside the support and has a spiral spring to provide elasticity.

[0008] As an optimization, the paper cutting assembly includes a rail seat fixedly installed on the bottom side of the fixed plate. A lead screw is rotatably connected inside the rail seat. A servo motor for driving the lead screw is fixedly installed at the end of the rail seat. A reciprocating slider is slidably connected inside the rail seat, and the lead screw is screwed into the reciprocating slider. A blade is detachably installed on one side of the front of the reciprocating slider. The blade can horizontally cut the kraft paper, thus cutting the kraft paper.

[0009] As an optimization, contact buttons are provided on both inner walls of the rail base, and the contact buttons are connected to the second servo motor. By pressing the contact buttons, the second servo motor can be stopped in time.

[0010] The beneficial effects of this utility model are: The circular barrel is equipped with a forming device. When the servo motor is started, it drives the rotating rod to rotate. This, in turn, causes the clamping rollers to rotate relative to each other through the meshing gears on both sides. This helps to pull the kraft paper downward. After the kraft paper is cut, the ratchet prevents the ratchet from reversing due to the limiting effect of the pawl. This, in turn, restricts the relative reversal of the clamping rollers, thus keeping the kraft paper taut and preventing it from being pulled back and loosening. Attached Figure Description

Detailed Implementation

[0013] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 A circular barrel winding forming device includes a housing 1 and a transmission base 2. The housing 1 contains a set of rotating rollers for tensioning kraft paper. A controller 3 is mounted on the top of the transmission base 2. A winding roller 4 is rotatably connected to the top of the transmission base 2, and abutment rollers for pressing against the kraft paper roll forming are also provided on the side of the winding roller 4. A guide roller 5 is rotatably connected to the top of the housing 1 on the side opposite to the winding roller 4. A fixing plate 6 is fixedly installed in the middle of the side of the housing 1 opposite to the winding roller 4. A tensioning device for clamping and positioning the kraft paper is provided on the top of the fixing plate 6. The bottom of the fixing plate 6 is equipped with a paper cutting component 8 for cutting kraft paper. By pulling the kraft paper vertically downward from the guide roller 5 through the tensioning and anti-loosening component 7 along the rotating roller group, the free end of the kraft paper is wrapped around the outside of the winding roller 4. It can be wound up and wound as the winding roller 4 rotates. After being wound into a cylindrical shape, the kraft paper can be cut by the paper cutting component 8. Since the tensioning and anti-loosening component 7 clamps and positions the kraft paper, it can prevent the kraft paper from being pulled back and loosened. Then the wound cylindrical body can be taken out. Please see Figure 2-3The tensioning and anti-loosening component 7 includes a support 9 fixedly installed on the top side of the fixed plate 6. A clamping roller 10 is provided between the two supports 9. A rotating rod 11 is fixedly installed in the center of the clamping roller 10. The clamping roller 10 is rotatably connected between the two supports 9 through the rotating rod 11. A gear 12 is fixedly installed on the outer side of one end of the rotating rod 11. A servo motor 13 for transmitting power to the rotating rod 11 is fixedly installed on the outer side of the support 9. An anti-reverse component for limiting the reverse rotation of the clamping roller 10 is provided inside the other support 9. By starting the servo motor 13, the rotating rod 11 will be driven to rotate. Therefore, the clamping roller 10 will be driven to rotate relative to each other through the gears 12 on both sides. This will help pull the kraft paper downward. At the same time, the anti-reverse component can prevent the clamping roller 10 from reversing, so that the kraft paper can always be tensioned. Please see Figure 2-3 The anti-reverse component includes a ratchet 14 rotatably connected inside the support 9. A spring-loaded pawl 15 is provided inside the support 9 and on the side of the ratchet 14. The pawl 15 is hinged inside the support 9 and has a spiral spring to provide elastic force. The pawl 15 is locked between adjacent teeth on the outside of the ratchet 14 by the elastic force. By limiting the ratchet 14 by the pawl 15, the ratchet 14 can be prevented from reversing, which in turn will limit the relative reversal of the clamping roller 10, so that the kraft paper can always be taut. Please see Figure 4 The paper cutting assembly 8 includes a rail seat 16 fixedly installed on the bottom side of the fixed plate 6. A lead screw 17 is rotatably connected inside the rail seat 16. A servo motor 2 18 for driving the lead screw 17 is fixedly installed at the end of the rail seat 16. A reciprocating slider 19 is slidably connected inside the rail seat 16, and the lead screw 17 is screwed into the reciprocating slider 19. A blade 20 is detachably installed on one side of the front of the reciprocating slider 19. By starting the servo motor 2 18, the lead screw 17 will rotate inside the reciprocating slider 19, which will then drive the reciprocating slider 19 to slide along the inner wall of the rail seat 16. Therefore, the blade 20 will horizontally cut the kraft paper, thereby achieving the function of cutting the kraft paper. Please see Figure 4 The inner walls on both sides of the rail base 16 are equipped with contact buttons, and the contact buttons are connected to the servo motor 18. By sliding the reciprocating slider 19 inside the rail base 16 to the end, the contact button can be pressed, which will turn off the servo motor 18. When the servo motor 18 is turned on again, it will drive the lead screw 17 to reverse, so that the blade 20 can cut the kraft paper back and forth.

[0016] In use, firstly, the kraft paper is pulled vertically downward from the guide roller 5 through the tensioning and anti-loosening component 7 along the rotating roller group. Then, the free end of the kraft paper is wrapped around the outside of the winding roller 4. As the winding roller 4 rotates, the kraft paper is wound up. After the kraft paper is wound into a cylindrical shape on the outside of the winding roller 4, the servo motor 18 is started to drive the lead screw 17 to rotate inside the reciprocating slider 19. This will drive the reciprocating slider 19 to slide along the inner wall of the rail seat 16, so that the blade 20 can horizontally cut the kraft paper for cutting. After that, the wound cylindrical body can be taken out. At the same time, by starting the servo motor 13 to drive the rotating rod 11 to rotate, the gears 12 on both sides will drive the clamping rollers 10 to rotate relative to each other, which will help pull the kraft paper downward. After the kraft paper is cut, the ratchet 14 is limited by the pawl 15 to prevent the ratchet 14 from reversing, which will limit the relative reversal of the clamping rollers 10. Therefore, the kraft paper can always be kept taut, and the kraft paper will not be pulled back loose.

[0017] In summary, the circular barrel body is wrapped with a forming device. By starting the servo motor 13, the rotating rod 11 is driven to rotate. This, in turn, drives the clamping rollers 10 to rotate relative to each other through the meshing gears 12 on both sides. This helps to pull the kraft paper downward. After the kraft paper is cut, the ratchet 14 is limited by the pawl 15, which prevents the ratchet 14 from reversing. This, in turn, restricts the relative reversal of the clamping rollers 10, thus keeping the kraft paper taut and preventing it from being pulled back and becoming loose.
