Description

Technical Field

[0001] This utility model relates to the field of pressure-sensitive paper production technology, specifically a pressure-sensitive paper coating machine. Background Technology

[0002] Pressure-sensitive paper, also known as pressure measuring film, is a visual industrial material that detects pressure distribution through color changes. In the production process of pressure-sensitive paper, in order to enable the substrate to have pressure sensing function, a pressure-sensitive paper coating machine is needed to evenly coat the surface of the substrate with pressure-sensitive coating.

[0003] When using existing pressure-sensitive paper coating machines, the operator usually uses an external traction mechanism to guide the substrate around the guide roller and positioning roller, and then the coating roller dips into the coating tank and, in conjunction with the metering roller, transfers the coating evenly to the surface of the substrate.

[0004] Existing pressure-sensitive paper coating machines have the following problems: during long-term operation, the coating in the coating tank may solidify or become uneven in composition due to evaporation, which affects the coating roller's coating work, thereby affecting the coating effect and reducing the qualified rate of the finished product. To address this, we propose a pressure-sensitive paper coating machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a pressure-sensitive paper coating machine. During the coating process, the coating inside the coating tank is stirred by a stirring mechanism. Continuous stirring makes the composition of the coating more uniform and delays the solidification of the coating, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure-sensitive paper coating machine, including a machine housing, a coating tank on the left side of the upper surface of the machine housing, a coating roller rotatably connected inside the machine housing via a rotating shaft, and a stirring mechanism;

[0007] The stirring mechanism includes a reciprocating screw, a slider, a rotating cylinder, a rotating rod, stirring blade one, stirring blade two, a limiting component, and a guiding component. The reciprocating screw is rotatably connected to the left side of the upper surface of the housing.

The rotating cylinder is rotatably connected to the rotating hole on the left side of the upper surface of the slider via a limiting component. The rotating rod is slidably connected to the sliding hole inside the rotating cylinder via a guiding component. Stirring blade one is provided on both the left and right sides of the lower end of the outer surface of the rotating cylinder, and stirring blade two is provided on both the front and rear sides of the lower end of the outer surface of the rotating rod. During the coating process, the stirring mechanism stirs the coating inside the coating tank. Continuous stirring makes the composition of the coating more uniform and delays the solidification of the coating.

[0008] Furthermore, the limiting component includes a gear and a rack. The gear is fixedly sleeved on the outer surface of the rotating cylinder, and a support frame is provided on the upper surface of the housing. A rack is provided on the left wall of the support frame. The gear and the rack mesh with each other, which facilitates the rotating cylinder to rotate while moving.

[0009] Furthermore, the limiting component also includes rib grooves and ribs. Rib grooves are provided on both the left and right sides of the inner wall of the sliding hole of the rotating cylinder, and ribs are provided on both the left and right sides of the outer surface of the rotating rod. The ribs are slidably connected to the interior of the adjacent rib grooves to facilitate limiting the rotating rod.

[0010] Furthermore, the guide assembly includes a spherical protrusion, a corrugated plate, a limiting ring, and a spring. The upper end of the rotating rod is provided with a spherical protrusion, the top wall of the support frame is provided with a corrugated plate, the upper end of the outer surface of the rotating rod is fixedly fitted with a limiting ring, and the outer surface of the rotating rod is movably fitted with a spring. The springs are all located between the lower surface of the limiting ring and the upper surface of the rotating cylinder, which facilitates the up and down movement of the rotating rod while it is rotating.

[0011] Furthermore, it also includes a microcontroller, which is fixedly connected to the left side of the housing. The input terminal of the microcontroller is electrically connected to an external power supply to facilitate the normal operation of the equipment.

[0012] Furthermore, a positioning roller and a guide roller are rotatably connected inside the housing. The outer front end of the rotating shaft on the coating roller and the reciprocating screw are both fixedly fitted with synchronous pulleys. The two synchronous pulleys are connected by a synchronous belt drive, which facilitates driving the reciprocating screw and the rotating shaft to rotate.

[0013] Furthermore, a motor is installed inside the housing. The front end of the motor's output shaft is fixedly connected to the rear end of the rotating shaft on the coating roller. The input end of the motor is electrically connected to the output end of the microcontroller to provide driving force.

[0014] Furthermore, an electric push rod is provided in the mounting groove on the upper surface of the housing. A bracket is provided at the lower end of the telescopic shaft of the electric push rod. A metering roller is rotatably connected inside the bracket. The input end of the electric push rod is electrically connected to the output end of the microcontroller, which facilitates the control of the height of the metering roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This pressure-sensitive paper coating machine has the following advantages:

[0016] During the coating process, the reciprocating screw moves through the slider rotating cylinder. While moving, the rotating cylinder and rotating rod rotate through the meshing relationship of gears and racks, causing stirring blade one and stirring blade two to rotate and stir the coating. During the movement of the rotating rod, through the combined action of the spherical protrusion, the corrugated plate, the limiting ring and the spring, stirring blade two moves back and forth and rotates while also moving up and down, providing an up and down shearing force to the coating. Continuous stirring makes the composition of the coating more uniform and delays the solidification of the coating. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-6This embodiment provides a technical solution: a pressure-sensitive paper coating machine, including a housing 1, a coating tank 5 on the left side of the upper surface of the housing 1, a coating roller 12 rotatably connected inside the housing 1 via a rotating shaft (the contact portion between the coating tank 5 and the coating roller 12 has a discharge port), a stirring mechanism 3, and a microcontroller 2, which is fixedly connected to the left side of the housing 1. The input end of the microcontroller 2 is electrically connected to an external power source. A positioning roller 13 and a guide roller 14 are rotatably connected inside the housing 1. Synchronous pulleys 7 are fixedly fitted onto the front ends of the rotating shaft on the coating roller 12 and the reciprocating screw 31. The two synchronous pulleys 7 are connected by a synchronous belt 8. A motor 4 is installed inside the housing 1. The front end of the output shaft of the motor 4 is fixedly connected to the rear end of the rotating shaft on the coating roller 12. The input end of the motor 4 is electrically connected to the output end of the microcontroller 2. An electric push rod 9 is installed in the mounting groove on the upper surface of the housing 1. A bracket 10 is installed at the lower end of the telescopic shaft of the electric push rod 9. A metering roller 11 is rotatably connected inside the bracket 10. The input end of the push rod 9 is electrically connected to the output end of the microcontroller 2. The operator moves the substrate from the left side of the guide roller 14, around the right side of the guide roller 14, and then through the positioning roller 13 and the coating roller 12. Finally, under the support of the support roller inside the housing 1, it is connected to the external traction mechanism. Through the control of the microcontroller 2, the telescopic shaft of the electric push rod 9 drives the metering roller 11 to move up and down through the bracket 10. When the metering roller 11 moves to the appropriate position, the external traction mechanism pulls the substrate to move. At the same time, the motor 4 is operated by the control of the microcontroller 2. The output shaft of the motor 4 drives the coating roller 12 to rotate through the rotating shaft on the coating roller 12. The rotation of the coating roller 12 picks up the coating through the outlet on the coating tank 5. Then, under the pressure of the metering roller 11, the coating is evenly distributed. After that, through the contact between the coating roller 12 and the substrate, the coating is transferred to the surface of the substrate to complete the coating work. During the coating process, the rotating shaft on the coating roller 12 drives the reciprocating screw 31 to rotate through the synchronous pulley 7 and the synchronous belt 8.

[0026] The stirring mechanism 3 includes a reciprocating screw 31, a slider 32, a rotating cylinder 33, a rotating rod 34, stirring blade 1 35, stirring blade 2 36, a limiting component 37, and a guiding component 38. The reciprocating screw 31 is rotatably connected to the left side of the upper surface of the housing 1. The slider 32 is slidably connected to the outer surface of the reciprocating screw 31 via a crescent lock. The rotating cylinder 33 is rotatably connected to the rotating hole on the left side of the upper surface of the slider 32 via the limiting component 37. The rotating rod 34 is slidably connected to the sliding hole inside the rotating cylinder 33 via the guiding component 38. Stirring blade 1 35 is provided on both the left and right sides of the lower end of the outer surface of the rotating cylinder 33. Stirring blade 2 36 is provided on both the front and rear sides of the lower end of the outer surface of the rotating rod 34. The limiting component 37 includes a gear 371 and a rack 372. A gear 371 is fixedly fitted onto the outer surface of the rotating cylinder 33. A support frame 6 is provided on the upper surface of the housing 1. A rack 372 is provided on the left wall of the support frame 6. The gear 371 and the rack 372 are meshed and connected. (A bellows is provided between the inner wall of the support frame 6 and the side of the slider 32. The bellows wraps around and shields the reciprocating screw 31. During the movement of the slider 32, the bellows on both sides contract and extend respectively, so that the reciprocating screw 31 is not affected by dust during long-term operation.) The limiting component 37 also includes a rib groove 373 and a rib 374. Ribs 373 are provided on both the left and right sides of the inner wall of the sliding hole of the rotating cylinder 33. Ribs 374 are provided on both the left and right sides of the outer surface of the rotating rod 34. The ribs 374 are slidably connected to the inner walls of the adjacent rib grooves 373. The guide assembly 38 includes a spherical protrusion 381, a corrugated plate 382, ​​a limiting ring 383, and a spring 384. The upper end of the rotating rod 34 is provided with the spherical protrusion 381, and the top wall of the support frame 6 is provided with the corrugated plate 382. The upper end of the outer surface of the rotating rod 34 is fixedly fitted with the limiting ring 383, and the outer surface of the rotating rod 34 is movably fitted with the spring 384. The springs 384 are all located between the lower surface of the limiting ring 383 and the upper surface of the rotating cylinder 33. The rotation of the reciprocating screw 31 drives the slider 32 to slide back and forth, and the slider 32 drives the rotating cylinder 33 to move. The rack 372 is fixed and drives the moving rotating cylinder 33 to rotate through the meshing gear 371. Under the restriction of the rib groove 373 and the rib 374, the rotating rod 34 rotates accordingly, causing the stirring blades to move. The first stirring blade 35 and the second stirring blade 36 rotate to stir the coating. When the rotating rod 34 moves, the spring 384 pushes the rotating rod 36 upward through the limiting ring 383 under the action of the rebound force, so that the outer surface of the spherical protrusion 381 is always in contact with the lower surface of the corrugated plate 382. When the spherical protrusion 381 moves from the concave part of the corrugated plate 382 to the protruding part of the corrugated plate 382, ​​the second stirring blade 36 moves downward. When the spherical protrusion 381 moves from the protruding part of the corrugated plate 382 to the concave part of the corrugated plate 382, ​​the second stirring blade 36 moves upward. This causes the second stirring blade 36 to move back and forth and rotate while making up and down reciprocating motions, providing an up and down shearing force to the coating, making the composition of the coating more uniform and delaying the solidification of the coating.

[0027] The working principle of the pressure-sensitive paper coating machine provided by this utility model is as follows: The operator starts from the left side of the guide roller 14, passes around the right side of the guide roller 14, then passes between the positioning roller 13 and the coating roller 12, and finally connects to the external traction mechanism under the support of the support roller inside the machine housing 1. Through the control of the microcontroller 2, the telescopic shaft of the electric push rod 9 drives the metering roller 11 to move up and down through the bracket 10. When the metering roller 11 moves to the appropriate position, the external traction mechanism pulls the substrate to move. At the same time, the motor 4 is operated by the control of the microcontroller 2. The output shaft of the motor 4 drives the coating roller 12 to rotate through the rotating shaft on the coating roller 12. The rotation of the coating roller 12 picks up the coating through the outlet on the coating tank 5. Then, under the pressure of the metering roller 11, the coating is evenly distributed. Then, through the contact between the coating roller 12 and the substrate, the coating is transferred to the surface of the substrate to complete the coating work. During the coating process, the rotating shaft on the coating roller 12 drives the reciprocating screw 31 to rotate through the synchronous pulley 7 and the synchronous belt 8. The rotation of 31 causes the slider 32 to slide back and forth, and the slider 32 drives the rotating cylinder 33 to move. The rack 372 remains stationary and drives the moving rotating cylinder 33 to rotate through the meshing gear 371. Under the restriction of the rib groove 373 and the rib 374, the rotating rod 34 rotates accordingly, causing the stirring blades 35 and 36 to rotate and stir the coating. When the rotating rod 34 moves, the spring 384 pushes the rotating rod 36 upward through the limiting ring 383 under the action of the rebound force, so that the outer surface of the spherical protrusion 381 is always When the spherical protrusion 381 moves from the recess of the wave plate 382 to the protrusion of the wave plate 382, ​​the stirring blade 36 moves downward. When the spherical protrusion 381 moves from the protrusion of the wave plate 382 to the recess of the wave plate 382, ​​the stirring blade 36 moves upward. This causes the stirring blade 36 to move back and forth and rotate while simultaneously moving up and down, providing a shearing force to the coating, making the composition of the coating more uniform and delaying the solidification of the coating.

[0028] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM32F4 series, the motor 4 can be a Y26334 / RV040, and the microcontroller 2 controls the operation of the motor 4 and the electric push rod 9 using methods commonly used in the prior art.
