Technical Field

[0001] This utility model relates to the field of thermal paper processing technology, and more specifically, to a thermal paper slitting mechanism. Background Technology

[0002] Thermal paper, also known as thermal fax paper, thermal recording paper, and thermal copy paper, is called thermal copy paper in Taiwan. It is a type of processed paper. Its manufacturing principle is to coat a layer of "thermal coating" onto high-quality base paper. During the processing of thermal paper, a slitting device is used to cut it into specific sizes for easy use later.

[0003] Patent application number 202320622662.7 discloses a thermal paper slitting device, including a machine body. A motor is installed on the bottom left side of the machine body, and the output end of the motor is connected to a drive wheel. A belt is driven to the outer surface of the drive wheel, and a driven wheel is driven to the other end of the belt. A conveying rod is provided on one side of the drive wheel, and a transmission rod is fixedly connected to the inner side of the driven wheel. A cutting device is provided on the outer surface of the transmission rod, and a placement rod is provided on the top of the transmission rod. A storage device is provided on the outer surface of the placement rod. A rotating block is provided at the end of the conveying rod away from the motor, and a fixing mechanism is provided between the rotating block and the machine body.

The conveying rod, clamping plate, rotating block, and limiting mechanism facilitate the positioning of the thermal paper on the conveying rod, ensuring that the thermal paper is fixed and does not deviate during cutting. The process is simple and easy to operate, making it convenient for operators.

[0004] Regarding the aforementioned technologies, the use of conveyor rods, clamps, rotating blocks, and limiting mechanisms facilitates the positioning of thermal paper on the conveyor rods, which helps maintain the stability of thermal paper slitting. However, the equipment lacks a tension adjustment structure, which may cause the thermal paper to loosen during conveying, potentially affecting the slitting quality of the thermal paper. Utility Model Content

[0005] To solve the above problems, this utility model provides a thermal paper slitting mechanism, which adopts the following technical solution:

[0006] A thermal paper slitting mechanism includes a base, a first mounting frame and a second mounting frame on the side wall of the base, support plates on both sides of the base, a first support rod rotatably mounted in the first mounting frame, a tension sensor in the first mounting frame, the tension sensor and the first support rod being staggered in the first mounting frame, a lifting cylinder fixedly mounted at the top of the first mounting frame, the piston shaft of the lifting cylinder slidingly passing through the first mounting frame, a tension adjusting component at the end of the piston shaft of the lifting cylinder, a mounting frame slidably mounted in the first mounting frame, a support roller rotatably mounted in the mounting frame, and a telescopic component at the bottom of the mounting frame.

[0007] Two symmetrically distributed second support rods are rotatably installed inside the second mounting frame. A cutting component is provided between the two second support rods. A limiting component is provided between the first mounting frame and the second mounting frame.

[0008] The base has a mounting slot at the top, which is located between two support plates. Waste collection components are provided on opposite sides of the two support plates.

[0009] By adopting the above technical solution, when the equipment is in use, the base is equipped with an unwinding structure and a rewinding structure, respectively, as in the prior art. The unwinding structure unwinds the paper, and the rewinding structure rewinds the slit paper. The rewinding structure also serves to pull the paper along. The equipment is equipped with a control structure, as in the prior art. The operator passes the paper through the equipment components in sequence, and the paper moves within the first mounting frame. The first mounting frame is equipped with a first support rod and a tension sensor. The tension sensor detects the tension of the paper during transport. Subsequently, the control structure drives the lifting cylinder to move the tension adjustment component, which in turn pushes the paper up and down. Through the cooperation of the first support rod and the tension sensor, the tension of the paper during transport can be controlled. The force helps maintain the tension of the paper during feeding, thus helping to maintain the quality of paper slitting. The paper slides on top of the support roller, and the bottom of the support roller is equipped with a telescopic component. The telescopic component pushes the support roller to rise and fall, and the support roller pushes the paper to rise and fall. This can help adjust the tension of the paper during feeding and also act as a buffer. When the paper is fed in the second mounting frame, it can be slit by the slitting component. Limiting components on both sides of the paper can correct the position of the paper during feeding, helping to prevent the paper from shifting during slitting and maintaining the quality of paper slitting. The equipment is also equipped with a waste collection component, which can reel in unqualified paper from both sides, helping to maintain the effectiveness of the equipment.

[0010] Furthermore, the tension adjustment assembly includes a lifting plate installed at the end of the piston shaft of the lifting cylinder. Two symmetrically distributed mounting blocks are provided below the lifting plate. An adjusting roller is rotatably installed between the two mounting blocks. Two symmetrically distributed connecting rods are fixedly installed at the top of the two mounting blocks and the bottom of the lifting plate. Slide grooves are provided on the inner walls of both sides of the first mounting frame. Sliding blocks are slidably installed in the two slide grooves. The bottom ends of the two sliding blocks are fixedly connected to the top of the mounting block on the same side.

[0011] By adopting the above technical solution, the lifting plate is driven to rise and fall by the lifting cylinder. The lifting plate, along with the connecting rod, the mounting block, and the adjusting roller, rises and falls synchronously. The adjusting roller pushes the paper, and the air channel at the interface adjusts the tension of the paper during feeding, which helps to maintain the stability of the paper during feeding. When the mounting block rises and falls, the mounting block slides in the same side groove along with the slider on the same side. The cooperation between the slider and the groove helps to maintain the stability of the adjusting roller's rise and fall.

[0012] Furthermore, the telescopic assembly includes two pillars fixedly installed on the top of the base. Each pillar has a movable groove at its top, and a support rod is slidably installed in each of the two movable grooves. A spring is fixedly connected between the bottom end of each support rod and the inner wall of the bottom end of the movable groove on the same side. Both support rods are fixedly connected to the bottom end of the mounting frame.

[0013] By adopting the above technical solution, when the paper slides above the support roller, the support roller, with the action of paper conveying, pushes the support rod to move into the movable groove on the same side. The support rod pushes the spring on the same side to contract, and the spring gives the support rod on the same side a rebound force, which plays a role in pushing the paper upward. This achieves the effect of assisting in adjusting the tension of the paper during conveying and can also play a buffering role, which is conducive to maintaining the stability of paper conveying.

[0014] Furthermore, each of the two support columns has two symmetrically distributed limiting grooves on its sidewalls, and limiting blocks are slidably installed in each limiting groove. The opposite side of the two limiting blocks on the same side is fixedly connected to the sidewall of the support column on the same side.

[0015] By adopting the above technical solution, when the support rod slides in the same side movable groove, the support rod slides in the same side limiting groove with the limiting block. The cooperation between the limiting block and the limiting groove helps to maintain the stability of the support rod's lifting and lowering, and helps to prevent the support rod from leaving the same side movable groove.

[0016] Furthermore, the slitting assembly includes a support column rotatably mounted in the second mounting frame. Multiple slitting blades arranged in a linear array are fixedly sleeved on the side wall of the support column. A mounting box is fixedly mounted on one side of the second mounting frame. A geared motor is fixedly mounted inside the mounting box. The end of the support column near the geared motor passes through the second mounting frame and extends into the mounting box. The end of the support column passing through the mounting box is fixedly connected to the end of the output shaft of the geared motor.

[0017] By adopting the above technical solution, when the paper slides on the support column, the side wall of the support column is equipped with a slitting blade. The support column and the slitting blade are driven to rotate by a geared motor, which can achieve the function of slitting the paper.

[0018] Furthermore, the limiting component includes a dual-axis cylinder fixedly installed on the top of the base. Movable plates are fixedly installed on the ends of the piston shafts of the dual-axis cylinder. Grooves are opened on the opposite side of the two movable plates. Multiple rollers arranged in a linear array are rotatably installed in the two grooves.

[0019] By adopting the above technical solution, two moving plates are driven to move synchronously by a dual-axis cylinder. The moving plates, along with the rollers, move synchronously toward the paper. By having the rollers contact the two sides of the paper, the position of the paper during feeding can be adjusted, which helps to avoid the phenomenon of paper deviation during feeding and helps to maintain the accuracy of paper cutting.

[0020] Furthermore, the waste collection assembly includes rotating rods rotatably mounted on opposite sides of two support plates. A first baffle is fixedly fitted onto the sidewalls of both rotating rods. Opposite ends of the two rotating rods penetrate the support plate on the same side. A second baffle is provided on the opposite side of each of the two rotating rods. A rubber column is fixedly installed on the opposite side of each of the two second baffles. A slot matching the rubber column is opened at the opposite end of each of the two rotating rods. A driven wheel is fixedly fitted onto the sidewall of the opposite end of each of the two rotating rods. A dual-axis motor is fixedly installed in the mounting slot. Assembling rods are fixedly installed at the ends of the two output shafts of the dual-axis motor. Opposite ends of the two assembling rods penetrate the support plate on the same side. A drive wheel is fixedly fitted onto the opposite end of each of the two assembling rods. A belt is provided between the drive wheel and the driven wheel on the same side.

[0021] By adopting the above technical solution, when the equipment cuts paper, waste material is generated on both sides of the paper. The operator wraps one end of the waste material around the side wall of the rotating rod, so that the waste material is located between the first and second baffles on the same side. Then, the two splicing rods are driven to rotate synchronously by a dual-axis motor. The splicing rods drive the drive wheel on the same side to rotate. The drive wheel drives the driven wheel on the same side to rotate via a belt. The driven wheel drives the rotating rod on the same side to rotate, which can play the role of winding up the waste material. This helps to prevent the waste material from affecting the subsequent paper conveying and makes it easier for the operator to clean up the waste material later. The second baffle and the rotating rod on the same side are fixed together by rubber pillars and slots. When it is necessary to remove the waste material roll, the operator pulls the second baffle, so that the rubber pillar installed on the side wall of the second baffle disengages from the slot on the same side, making it easy for the operator to remove the waste material roll.

[0022] In summary, this utility model has the following beneficial technical effects:

[0023] (1) In this utility model, the tension of the paper is detected by the tension sensor and the tension adjustment component is driven to rise and fall by the lifting cylinder, which can play the role of adjusting the tension of the paper during the conveying process, which is beneficial to maintaining the stability of the paper during the cutting process.

[0024] (2) In this utility model, the mounting frame, support roller and telescopic component work together to help adjust the tension of the paper during feeding, and the limiting component can correct the position of the paper during feeding, which helps to maintain the stability of the paper during feeding.

[0036] The following is in conjunction with the appendix Figures 1-6 The present invention will be described in further detail below.

[0037] Please see Figures 1-6 A thermal paper slitting mechanism includes a base 1, a first mounting frame 2 and a second mounting frame 3 on the side wall of the base 1, and support plates 5 on both sides of the base 1. A first support rod 10 is rotatably mounted in the first mounting frame 2. A tension sensor is provided in the first mounting frame 2. The tension sensor and the first support rod 10 are located in a staggered distribution within the first mounting frame 2. A lifting cylinder 6 is fixedly mounted at the top of the first mounting frame 2. The piston shaft of the lifting cylinder 6 slides through the first mounting frame 2. A tension adjusting assembly is provided at the end of the piston shaft of the lifting cylinder 6. The tension adjusting assembly includes a lifting plate 32 mounted at the end of the piston shaft of the lifting cylinder 6. Two symmetrically distributed mounting blocks 13 are provided below the lifting plate 32. An adjusting roller 11 is rotatably mounted between the two mounting blocks 13. Two symmetrically distributed connecting rods 14 are fixedly mounted at the top of the two mounting blocks 13 and the bottom of the lifting plate 32. Slide grooves 15 are provided on the inner walls of both sides of the first mounting frame 2. Sliding sliders 16 are slidably mounted in the two slide grooves 15. The bottom ends of the two sliders 16 are fixedly connected to the top ends of the mounting blocks 13 on the same side.

[0038] When the equipment is in use, the base 1 has an unwinding structure and a rewinding structure at both ends, which are based on existing technology. The unwinding structure unwinds the paper, and the rewinding structure rewinds the slit paper. The rewinding structure can also pull the paper to move. The equipment is also equipped with a control structure based on existing technology. The operator passes the paper through the equipment components in sequence. The paper moves within the first mounting frame 2. The first mounting frame 2 is equipped with a first support rod 10 and a tension sensor. The tension sensor can detect the tension of the paper during transport. Then, the lifting cylinder 6 drives the lifting plate 32 to rise and fall. The lifting plate 32, along with the connecting rod 14, the mounting block 13, and the adjusting roller 11, rises and falls synchronously. The adjusting roller 11 pushes the paper, and the air duct at the interface adjusts the tension of the paper during transport, which helps to maintain the stability of the paper during transport. When the mounting block 13 rises and falls, the mounting block 13 slides the slider 16 on the same side within the slide groove 15 on the same side. The cooperation of the slider 16 and the slide groove 15 helps to maintain the stability of the adjusting roller 11 during rise and fall.

[0039] An mounting frame 8 is slidably installed inside the first mounting frame 2. A support roller 7 is rotatably installed inside the mounting frame 8. A telescopic component is provided at the bottom of the mounting frame 8. The telescopic component includes two pillars 12 fixedly installed at the top of the base 1. Each of the two pillars 12 has a movable groove 33 at its top. A support rod 9 is slidably installed in each of the two movable grooves 33. A spring 34 is fixedly connected between the bottom end of each support rod 9 and the inner wall of the bottom end of the movable groove 33 on the same side. Both support rods 9 are fixedly connected to the bottom end of the mounting frame 8. When the paper slides above the support roller 7, the support roller 7, with the action of paper conveying, pushes the support rod 9 to move into the movable groove 33 on the same side. The support rod 9 pushes the spring 34 on the same side to contract. The spring 34 gives the support rod 9 on the same side a rebound force, which pushes the paper upward, achieving the effect of assisting in adjusting the tension of the paper during conveying and also playing a buffering role, which helps to maintain the stability of the paper during conveying.

[0040] Two symmetrically distributed limiting grooves 35 are provided on the side walls of the two support columns 12. Limiting blocks 36 are slidably installed in the limiting grooves 35. The opposite side of the two limiting blocks 36 on the same side is fixedly connected to the side wall of the support rod 9 on the same side. When the support rod 9 slides in the movable groove 33 on the same side, the support rod 9 slides in the limiting groove 35 on the same side with the limiting blocks 36. The cooperation between the limiting blocks 36 and the limiting grooves 35 helps to maintain the stability of the lifting and lowering of the support rod 9 and helps to prevent the support rod 9 from disengaging from the movable groove 33 on the same side.

[0041] Two symmetrically distributed second support rods 19 are rotatably mounted inside the second mounting frame 3. A slitting assembly is provided between the two second support rods 19. The slitting assembly includes a support column 17 rotatably mounted inside the second mounting frame 3. Multiple slitting blades 18 arranged in a linear array are fixedly sleeved on the side wall of the support column 17. A mounting box 4 is fixedly mounted on one side of the second mounting frame 3. A geared motor 29 is fixedly mounted inside the mounting box 4. The end of the support column 17 near the geared motor 29 passes through the second mounting frame 3 and extends into the mounting box 4. The end of the support column 17 passing through the mounting box 4 is fixedly connected to the end of the output shaft of the geared motor 29. When the paper slides on the support column 17, the slitting blades 18 on the side wall of the support column 17 drive the support column 17 and the slitting blades 18 to rotate, thereby slitting the paper.

[0042] A limiting component is provided between the first mounting frame 2 and the second mounting frame 3. The limiting component includes a dual-axis cylinder 30 fixedly mounted on the top of the base 1. Movable plates 31 are fixedly mounted on the ends of the piston shafts of the dual-axis cylinder 30. Grooves 38 are provided on opposite sides of the two movable plates 31. Multiple rollers 37 arranged in a linear array are rotatably mounted in the two grooves 38. The dual-axis cylinder 30 drives the two movable plates 31 to move synchronously. The movable plates 31 move synchronously towards the paper direction with the rollers 37. By having the rollers 37 contact the two sides of the paper, the position of the paper can be adjusted during the feeding process, which helps to avoid the phenomenon of paper deviation during feeding and helps to maintain the accuracy of paper cutting.

[0043] The base 1 has a mounting groove 20 at its top, located between two support plates 5. Each support plate 5 has a waste collection assembly on its opposite side. Each waste collection assembly includes a rotating rod 22 rotatably mounted on one of the opposite sides of the two support plates 5. A first baffle 23 is fixedly fitted onto the side wall of each of the two rotating rods 22. Opposite ends of the two rotating rods 22 pass through the support plate 5 on the same side. Each rotating rod 22 has a second baffle 24 on its opposite side, and rubber posts are fixedly mounted on opposite sides of each of the two second baffles 24. Two rotating rods 22 have slots at their opposite ends that match the rubber posts on the same side. Driven wheel discs 27 are fixedly fitted on the opposite sidewalls of the two rotating rods 22. A dual-axis motor 21 is fixedly installed in the mounting groove 20. Assembling rods 25 are fixedly installed at the ends of the two output shafts of the dual-axis motor 21. The opposite ends of the two assembly rods 25 pass through the support plate 5 on the same side. Drive wheel discs 26 are fixedly fitted on the opposite ends of the two assembly rods 25. A belt 28 is provided between the drive wheel disc 26 and the driven wheel disc 27 on the same side.

[0044] When the equipment cuts paper, waste material is generated on both sides of the paper. The operator wraps one end of the waste material around the side wall of the rotating rod 22, so that the waste material is located between the first baffle 23 and the second baffle 24 on the same side. Then, the two splicing rods 25 are driven to rotate synchronously by the dual-axis motor 21. The splicing rods 25 drive the drive wheel 26 on the same side to rotate. The drive wheel 26 drives the driven wheel 27 on the same side to rotate through the belt 28. The driven wheel 27 drives the rotating rod 22 on the same side to rotate, which can play the role of winding up the waste material. This helps to prevent the waste material from affecting the subsequent paper conveying and makes it easier for the operator to clean up the waste material later. The second baffle 24 and the rotating rod 22 on the same side are fixed together by rubber pillars and slots. When it is necessary to remove the waste material roll, the operator pulls the second baffle 24, so that the rubber pillar installed on the side wall of the second baffle 24 disengages from the slot on the same side, making it easier for the operator to remove the waste material roll.

[0045] The implementation principle of this utility model embodiment is as follows: When the equipment is in use, the base 1 has an unwinding structure and a winding structure respectively at both ends. The unwinding structure unwinds the paper, and the winding structure winds up the slit paper. The winding structure can also pull the paper to move. The equipment is equipped with a control structure of the prior art. The operator passes the paper through the equipment components in sequence. The paper moves within the first mounting frame 2. The first mounting frame 2 is equipped with a first support rod 10 and a tension sensor. The tension sensor can detect the tension of the paper during feeding. Then, the control structure drives the lifting cylinder 6 to move the tension adjustment component. The tension adjustment component pushes the paper up and down. Through the cooperation of the first support rod 10 and the tension sensor, the paper feeding can be achieved. The tension during feeding helps maintain the tightness of the paper during transport, thus helping to maintain the quality of paper slitting. The paper slides on top of the support roller 7, and the bottom of the support roller 7 is equipped with a telescopic component. The telescopic component pushes the support roller 7 up and down, and the support roller 7 pushes the paper up and down, which can help adjust the tension of the paper during transport and also act as a buffer. When the paper is transported in the second mounting frame 3, it can be slit by the slitting component. Limiting components on both sides of the paper can correct the position of the paper during transport, which helps to prevent the paper from shifting during slitting and helps to maintain the quality of paper slitting. The equipment is also equipped with a waste collection component, which can reel in unqualified paper from both sides, which helps to maintain the effectiveness of the equipment.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
