Description
Technical Field
[0001] The utility model relates to the technical field of carbonless copy paper processing, in particular to a coating machine for carbonless copy paper processing. Background Technique
[0002] Carbonless copy paper is a type of invisible copy paper with the functions of direct copying and direct color development. Its color development mainly occurs as follows: under the action of external force, the force-sensitive pigment and oil solution in the microcapsules overflow and react with the developer after contacting it, thereby playing a role in copying. During the processing of carbonless copy paper, a coating machine is required to perform a coating operation on its surface. Some coating machines include a coating box. Both side walls of the coating box near the top are provided with a cloth inlet hole and a cloth outlet hole. A cloth body passes through the inside of the cloth inlet hole and the cloth outlet hole. Inside the coating box and above and below the cloth body, there are also rotating rods. Both ends of the rotating rod penetrate the coating box and are rotatably connected to it through bearings. The surfaces of the rotating rods are sleeved and fixedly connected with coating rollers. A filter screen is fixed inside the coating box. In the utility model, the coating liquid in the coating box is pumped out by a liquid pump and transported to the liquid infusion plate through a T-shaped pipe and a liquid inlet pipe, and at the same time, the coating liquid is transported to the coating roller, which can achieve the effect of not worrying about the reduction of the coating liquid resulting in the inability of the coating roller surface to adhere to the coating liquid. However, during the coating process of the carbonless copy paper by the device, the spatial position of the coating roller is fixed, and the surface of the carbonless copy paper is coated by rotating the coating roller. When a certain position on the surface of the coating roller does not adhere to the coating liquid, with the single rotation of the coating roller, it is easy to cause uneven coating on the surface of the carbonless copy paper, which needs to be improved. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a coating machine for carbonless copy paper processing. During the coating process of the carbonless copy paper by this device, through the transmission element, the coating roller can rotate and move longitudinally back and forth along the surface of the carbonless copy paper, so that the coating contact surface between the coating roller and the carbonless copy paper is always in a relatively changing state, thereby improving the coating uniformity of the device for the carbonless copy paper, and effectively solving the problems in the background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A coating machine for carbonless copy paper processing, including a coating shell and a uniform coating mechanism;
[0005] Coating shell: Its rear wall is provided with vertically symmetrically distributed rectangular liquid outlet seats through fixed rods, and permeable cotton is provided at the liquid outlet of each rectangular liquid outlet seat;
[0006] Uniform coating mechanism: It includes a reciprocating lead screw and a coating roller. The reciprocating lead screws are symmetrically arranged on the front wall of the coating shell. Coating rollers are threadedly connected to the outer sides of the reciprocating lead screws. The coating rollers are respectively installed in cooperation with the adjacent rectangular liquid outlet seats. During the coating process of carbonless copy paper, through the transmission element, while the coating rollers rotate, they can move longitudinally back and forth along the surface of the carbonless copy paper, so that the coating contact surface between the coating rollers and the carbonless copy paper is always in a relatively changing state, thereby improving the coating uniformity of the device for carbonless copy paper.
[0007] Furthermore, a control switch is provided on the front side of the coating shell. The input end of the control switch is electrically connected to an external power supply, which is convenient for controlling electrical components.
[0008] Furthermore, the uniform coating mechanism further includes a rotating shaft, a rotating seat and a telescopic rod. The rotating shafts are respectively rotatably connected to the rear wall of the coating shell through bearings. Rotating seats are provided at the front ends of the rotating shafts. Uniformly distributed telescopic rods are provided on the front sides of the rotating seats. The telescopic ends of the telescopic rods are fixedly connected to the adjacent coating rollers, so that the coating part of the carbonless copy paper can rotate through the rotating shaft.
[0009] Furthermore, the uniform coating mechanism further includes a fixed seat, a driving motor and a gear. The fixed seat is arranged at the rear side of the coating shell. A driving motor is provided at the rear side of the fixed seat. The input end of the driving motor is electrically connected to the output end of the control switch. The output shaft of the driving motor is fixedly connected to the upper rotating shaft. Gears are provided at the rear ends of the rotating shafts, and the gears are meshed with each other to provide power for the device to uniformly coat the carbonless copy paper.
[0010] Furthermore, a liquid storage tank is provided on the upper side of the coating shell. A liquid infusion pipe penetrates through the lower end of the front wall of the liquid storage tank. The lower end of the liquid infusion pipe passes through the top wall of the coating shell and is connected to the rectangular liquid outlet seat through a bifurcated pipe to supply coating liquid during the coating process of the carbonless copy paper.
[0011] Furthermore, material openings are formed on both the left and right walls of the coating shell. Uniformly distributed auxiliary material rollers are rotatably connected between the front and rear walls of the coating shell through bearings to provide auxiliary support during the coating process of the carbonless copy paper.
[0012] Furthermore, symmetrically distributed observation windows are installed on the front side of the coating shell, which is convenient for observing the coating situation of the carbonless copy paper inside the carbonless copy paper processing coater.
[0013] Compared with the prior art, the beneficial effects of the present utility model are: This carbonless copy paper processing coater has the following advantages:
[0014] When performing a coating operation on carbonless copy paper, the control switch starts the drive motor. Through the meshing between gears and the threaded connection between the reciprocating lead screw and the coating roller, the coating roller can rotate and longitudinally reciprocate back and forth along the surface of the carbonless copy paper. This makes the coating contact surface between the coating roller and the carbonless copy paper always in a relatively changing state, increasing the longitudinal coating contact range between the coating roller and the surface of the carbonless copy paper, and thus improving the coating uniformity of the device for carbonless copy paper.

[0021] Please refer to Figures 1-4 , this embodiment provides a technical solution: A carbonless copy paper processing coater, including a coating shell 1 and a uniform coating mechanism 3;
[0022] Coating shell 1: Its rear wall is provided with vertically symmetrically distributed rectangular liquid outlet seats 6 through fixing rods. Permeable cotton is provided at the liquid outlet of each rectangular liquid outlet seat 6. A liquid storage tank 4 is provided on the upper side of the coating shell 1. The lower end of the front wall of the liquid storage tank 4 is provided with a liquid delivery pipe 5 penetrating through it. The lower end of the liquid delivery pipe 5 passes through the top wall of the coating shell 1 and is connected to the rectangular liquid outlet seat 6 through a bifurcated pipe. Feeding ports 8 are provided on both the left and right walls of the coating shell 1. Uniformly distributed auxiliary feeding rollers 7 are rotatably connected between the front and rear walls of the coating shell 1 through bearings. Symmetrically distributed observation windows 9 are installed on the front side of the coating shell 1. When using the device to perform coating operations on carbonless copy paper, the carbonless copy paper is driven by an external traction device to pass through the coating shell 1 from right to left. The carbonless copy paper passes through the feeding port 8, the vertical gap formed by two vertically adjacent auxiliary feeding rollers 7, and the coating gap formed by two coating rollers 32. The coating liquid in the liquid storage tank 4 enters the corresponding rectangular liquid outlet seat 6 respectively through the liquid delivery pipe 5 and the bifurcated pipe under the action of its own gravity. The coating liquid oozes out through the permeable cotton at the feeding port of the rectangular liquid outlet seat 6 through capillary action and covers the corresponding coating roller 32. The auxiliary feeding rollers 7 assist in supporting the carbonless copy paper during the coating process. The observation window 9 facilitates observing the coating situation of the carbonless copy paper inside the device;
[0023] Uniform coating mechanism 3: It includes a reciprocating lead screw 31 and a coating roller 32. The reciprocating lead screws 31 are symmetrically arranged on the front wall of the coating housing 1. Coating rollers 32 are threadedly connected to the outside of the reciprocating lead screws 31. The coating rollers 32 are respectively installed in cooperation with the adjacent rectangular liquid outlet seats 6. A control switch 2 is provided on the front side of the coating housing 1. The input end of the control switch 2 is electrically connected to an external power supply. The uniform coating mechanism 3 further includes a rotating shaft 33, a rotating seat 34, and a telescopic rod 35. The rotating shafts 33 are rotatably connected to the rear wall of the coating housing 1 through bearings. Rotating seats 34 are provided at the front ends of the rotating shafts 33. Uniformly distributed telescopic rods 35 are provided on the front sides of the rotating seats 34. The telescopic ends of the telescopic rods 35 are fixedly connected to the adjacent coating rollers 32. The uniform coating mechanism 3 further includes a fixed seat 36, a driving motor 37, and a gear 38. The fixed seat 36 is arranged at the rear side of the coating housing 1. A driving motor 37 is provided at the rear side of the fixed seat 36. The input end of the driving motor 37 is electrically connected to the output end of the control switch 2. The output shaft of the driving motor 37 is fixedly connected to the upper rotating shaft 33. Gears 38 are provided at the rear ends of the rotating shafts 33. The gears 38 are meshed with each other. During the coating process of carbonless copy paper, the control switch 2 starts the driving motor 37 so that its output shaft drives the upper rotating shaft 33 to rotate. The upper rotating shaft 33 drives the lower rotating shaft 33 to rotate synchronously in reverse through the meshing connection between the gears 38. The upper rotating shaft 33 drives the rotating seat 34 to rotate forward. The rotating seat 34 drives the upper coating roller 32 to rotate forward through the telescopic end of the telescopic rod 35, thereby coating the upper surface of the carbonless copy paper. The lower coating roller 32 rotates in reverse by the same principle to coat the lower surface of the carbonless copy paper. During the rotation of the coating roller 32, it moves longitudinally back and forth along the reciprocating lead screw 31 through threaded connection, so that during the flipping coating operation of the coating roller 32 on the surface of the carbonless copy paper, the two coating rollers 32 can move longitudinally back and forth along the surface of the carbonless copy paper, making the coating contact surface between the coating roller 32 and the carbonless copy paper always change longitudinally, increasing the longitudinal coating contact range between the coating roller 32 and the surface of the carbonless copy paper, and further improving the coating uniformity of the device for carbonless copy paper. During the coating process of the device for carbonless copy paper, through the transmission element, the coating roller 32 can rotate and move longitudinally back and forth along the surface of the carbonless copy paper at the same time, making the coating contact surface between the coating roller 32 and the carbonless copy paper always in a relatively changing state, and further improving the coating uniformity of the device for carbonless copy paper.
[0024] The working principle of a carbonless copy paper processing coater provided by the present utility model is as follows: When using the device to coat the carbonless copy paper, the carbonless copy paper is driven by an external traction device to pass through the coating shell 1 from right to left. The carbonless copy paper passes through the vertical gap formed by the material port 8 and two vertically adjacent auxiliary material rollers 7, and the coating gap formed by two coating rollers 32. The coating liquid in the liquid storage tank 4 enters the corresponding rectangular liquid outlet seat 6 through the liquid delivery pipe 5 and the bifurcated pipe under the action of its own gravity. The coating liquid oozes out through the permeable cotton at the material port of the rectangular liquid outlet seat 6 through capillary action and covers the corresponding coating roller 32. During the coating process of the carbonless copy paper, the control switch 2 starts the drive motor 37 so that its output shaft drives the upper rotating shaft 33 to rotate. The upper rotating shaft 33 is connected by meshing between the gears 38 so that the lower rotating shaft 33 rotates synchronously in reverse. The upper rotating shaft 33 drives the rotating seat 34 to rotate forward. The rotating seat 34 drives the upper coating roller 32 to rotate forward through the telescopic end of the telescopic rod 35, so as to coat the upper surface of the carbonless copy paper. The lower coating roller 32 rotates in reverse by the same principle to coat the lower surface of the carbonless copy paper. During the rotation of the coating roller 32, it moves longitudinally back and forth along the reciprocating lead screw 31 through a threaded connection, so that during the process of the coating roller 32 flipping and coating the surface of the carbonless copy paper, the two coating rollers 32 can move longitudinally back and forth along the surface of the carbonless copy paper, so that the coating contact surface between the coating roller 32 and the carbonless copy paper is always longitudinally changed, increasing the longitudinal coating contact range between the coating roller 32 and the surface of the carbonless copy paper, thereby improving the coating uniformity of the device on the carbonless copy paper. The auxiliary material roller 7 is used to assist in supporting the carbonless copy paper during the coating process, and the observation window 9 is convenient for observing the coating situation of the carbonless copy paper inside the device.
