Description

Technical Field

[0001] This application relates to the field of tissue paper production and processing technology, and in particular to a cream coating machine. Background Technology

[0002] A coating machine is a device specifically designed to uniformly coat a layer of liquid or semi-solid substance onto the surface of paper or other substrates. In the prior art, the feeding roller of the coating mechanism inside the coating machine is located above the hopper, which contains coating agent. The feeding roller surface contacts the cream, driving the cream to coat the surface of the paper product. However, as the amount of cream decreases, the contact area between the feeding roller and the cream decreases, which in turn affects the coating effect of the paper.

[0003] In related technologies, to ensure a good contact area between the feeding roller and the cream, elastic units are added to both sides of the hopper, and the weight of the hopper is reduced by reducing the weight of the cream. In this way, the hopper can be lifted under the elastic action of the spring, thereby ensuring that the cream always keeps in contact with the feeding roller.

[0004] However, due to the large amount of cream used, not only do staff need to regularly observe the amount of cream in the hopper, but the springs are also prone to fatigue, which leads to changes in the microstructure, affecting the springs' recovery ability and thus affecting the contact area between the cream and the feeding roller.

[0005] Therefore, those skilled in the art have provided a cream coating machine to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a cream coating machine.

[0007] The cream coating machine provided in this application adopts the following technical solution:

[0008] A cream coating machine, comprising:

[0009] A frame is fitted with a feeding roller for coating, one end of which is fitted with a motor for rotating it, and a pressure roller is elastically mounted inside the frame and on top of the feeding roller.

[0010] A feeding mechanism, installed on one side of the top of the frame, includes a hopper fitted around the bottom of the feeding roller and a storage tank on one side of the hopper. One side of the storage tank is connected to an external cream conveying pipe. A peristaltic pump is installed on the top of the frame. The inlet end of the peristaltic pump is connected to the storage tank, and the outlet end of the peristaltic pump is connected to a connecting pipe. The peristaltic pump and the connecting pipe are connected to each other to draw cream from the storage tank and add it to the inside of the hopper.

[0011] An automatic feeding assembly, installed inside the hopper, is used to automatically turn the peristaltic pump on or off.

[0012] By adopting the above technical solution, the cream in the storage tank can be drawn into the hopper, so that it can be added in time when the cream in the hopper decreases.

[0013] Preferably, the automatic feeding assembly includes four fixed plates fixedly installed on the inner wall of the hopper, a float plate slidably installed inside the hopper, vertical rods fixedly installed around the top of the float plate, the top of the vertical rods penetrating the fixed plates and extending to the top of the fixed plates, a pressure plate fixedly installed at the top of the vertical rods, a protective shell penetrating one side of the surface of the fixed plate, a pressure head penetrating the top of the protective shell, and a touch switch installed at the bottom of the inner cavity of the protective shell;

[0014] By adopting the above technical solution, the peristaltic pump can be automatically driven to work when the amount of cream in the hopper decreases, so as to facilitate the automatic addition of cream.

[0015] Preferably, a return spring is fixedly installed at one end of the protective shell inside the pressure head, and the bottom end of the return spring is fixedly connected to the bottom of the inner cavity of the protective shell for resetting the pressure head;

[0016] By adopting the above technical solution, the pressure head can be driven to rise in time when the pressure plate rises, avoiding prolonged contact between the pressure head and the touch switch, which would affect the sensitivity of the touch switch.

[0017] Preferably, a mounting base is installed through the other side of the surface of the fixing plate, and ball bearings are installed around the inner wall of the mounting base. Sliding grooves are formed around the outer wall of the vertical rod, and the ball bearings are slidably connected to the sliding grooves.

[0018] By adopting the above technical solution, the sliding effect between the mounting base and the vertical rod can be increased, so that the pressure plate can be driven to descend in time when the cream descends.

[0019] Preferably, a filter plate is fixedly installed inside the float plate to filter impurities in the cream;

[0020] Preferably, a time relay is installed on one side of the top of the frame, the electrical output terminal of the touch switch is connected to the electrical input terminal of the time relay, and the electrical output terminal of the time relay is connected to the electrical input terminal of the peristaltic pump for driving the peristaltic pump.

[0021] By adopting the above technical solution, the peristaltic pump can be turned on automatically, making it convenient to add cream in a timely manner.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. In this cream coating machine, when the cream in the hopper decreases, the float plate can drive the vertical rod to descend and use the pressure plate to press the pressure head, thereby pressing the touch switch to open the peristaltic pump, so as to draw the cream in the storage box into the hopper. This realizes the automatic addition of cream in the hopper, and the contact area between the feeding roller and the cream can be ensured without the need for the use of the elastic unit.

[0024] 2. This cream coating machine utilizes the sliding connection between the ball bearings and the chute to increase the sliding effect between the vertical rod and the mounting base when the cream is added or removed in the hopper. This allows the float to move promptly when the cream is reduced, avoiding frictional resistance between the vertical rod and the mounting base, which would affect the lifting and lowering of the vertical rod and prevent the cream from being added in a timely manner.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a cream coating machine. (Refer to...) Figure 1-4 A cream coating machine, comprising:

[0032] A frame 1 is equipped with a feeding roller 2 for coating. A motor for rotating the feeding roller 2 is installed at one end. A pressure roller 3 is elastically installed inside the frame 1 and on top of the feeding roller 2.

[0033] A feeding mechanism 4 is installed on one side of the top of the frame 1 and includes a hopper 41 fitted onto the bottom of the feeding roller 2, and a storage tank 42 on one side of the hopper 41. One side of the storage tank 42 is connected to an external cream conveying pipe. A peristaltic pump 43 is installed on the top of the frame 1. The inlet end of the peristaltic pump 43 is connected to the storage tank 42, and the outlet end of the peristaltic pump 43 is connected to a connecting pipe 44. The peristaltic pump 43 and the connecting pipe 44 are connected to each other to draw cream from the storage tank 42 and add it to the inside of the hopper 41.

[0034] Reference Figure 3 as well as Figure 4 An automatic feeding assembly 45 is installed inside the hopper 41 to automatically turn the peristaltic pump 43 on or off. The automatic feeding assembly 45 includes four fixed plates 451 fixedly installed on the inner wall of the hopper 41. A float plate 452 is slidably installed inside the hopper 41. Vertical rods 453 are fixedly installed around the top of the float plate 452. The top of the vertical rods 453 passes through the fixed plates 451 and extends to the top of the fixed plates 451. A pressure plate 454 is fixedly installed at the top of the vertical rods 453. A protective shell 455 is installed through one side of the surface of the fixed plate 451. A pressure head 456 is provided through the top of the protective shell 455. A touch switch 457 is installed at the bottom of the inner cavity of the protective shell 455.

[0035] In this embodiment, when the cream decreases in the hopper 41, the float 452 moves the vertical rod 453 down with the cream, thereby pressing the pressure head 456 and the touch switch 457 with the pressure plate 454, and simultaneously turning on the peristaltic pump 43 to work, drawing out the cream from the storage box 42 and adding it to the inside of the hopper 41.

[0036] A time relay 49 is installed on one side of the top of the frame 1. The electrical output terminal of the touch switch 457 is connected to the electrical input terminal of the time relay 49. The electrical output terminal of the time relay 49 is connected to the electrical input terminal of the peristaltic pump 43 to drive the peristaltic pump 43.

[0037] By utilizing the cooperation between the peristaltic pump 43 and the time relay 49, the working time of the peristaltic pump 43 can be set. Utilizing the energizing delay characteristic of the time relay 49, the time relay 49 immediately begins to delay after receiving the input signal. Only after the delay is completed will its execution part output a signal to manipulate the control circuit. When the input signal disappears, the relay immediately returns to its state before the operation.

[0038] Please continue to refer to Figure 4A return spring 458 is fixedly installed at one end of the protective shell 455 inside the pressure head 456. The bottom end of the return spring 458 is fixedly connected to the bottom of the inner cavity of the protective shell 455 to reset the pressure head 456.

[0039] In this embodiment, when the pressure plate 454 rises with the vertical rod 453, the pressure head 456 will automatically rise with the elasticity of the reset spring 458 and separate from the touch switch 457.

[0040] Please continue to refer to Figure 4 A mounting base 46 is installed through the other side of the surface of the fixing plate 451. Ball bearings 47 are installed around the inner wall of the mounting base 46. Slide grooves 48 are opened around the outer wall of the vertical rod 453. The ball bearings 47 and the slide grooves 48 are slidably connected.

[0041] In this embodiment, the sliding effect between the mounting base 46 and the vertical rod 453 can be increased so that the pressure plate 454 can be driven down in time when the cream is lowered.

[0042] Reference Figure 2 as well as Figure 3 A filter plate 459 is fixedly installed inside the float plate 452 for filtering impurities in the cream.

[0043] In this embodiment, since the cream is injected from bottom to top, the float plate 452 can filter the impurities inside the cream when the feeding roller 2 comes into contact with it, thus preventing impurities from adhering to the paper and affecting product quality.

[0044] The implementation principle of a cream coating machine according to an embodiment of this application is as follows: As the coating machine continues to work, the amount of cream inside the hopper 41 continues to decrease. When the cream decreases in the hopper 41, the float plate 452 drives the vertical rod 453 to descend along with the cream. The pressure plate 454 presses the pressure head 456 and the touch switch 457, and the peristaltic pump 43 is turned on at the same time to draw out the cream inside the storage box 42 and add it to the inside of the hopper 41.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
