[0002] The coating machine is used to apply medicine to the material. Its structural reference application number is CN202120317381.1, and its name is a Chinese utility model patent for an upper wheel medicine coating machine suitable for an assembly line. The transfer mechanism is an important component of the coating machine. The existing transfer mechanism has the disadvantages of uneven coating and dripping of medicine during the transfer process, which is prone to uneven transfer, affecting product quality and production efficiency, and there is a waste of medicine. And because the transfer mechanism basically adopts a fixed structure, it is only suitable for the coating needs of a single specification of fabric. When the thickness of the fabric changes, the roller needs to be removed and the position spacing needs to be readjusted. Such operation is not only prone to uneven coating due to uneven materials, but also time-consuming and labor-intensive, affecting production efficiency, but also unable to fully guarantee the coating accuracy of the fabric.

[0013] Furthermore, the transmission assembly is a pulley transmission assembly.

[0014] The beneficial effects of the present invention are as follows: a coating machine, a medicine tank is used to store medicine, and a water-passing shaft is immersed in the water tank.

The thoroughness and efficiency of the device are improved. The rotating support roller is installed on the frame through a floating block. The floating block can be lifted and lowered by a damping rod. When the material passes through the rotating support roller, the rotating support roller will float up and down according to the different heights of the material surface, thereby ensuring the close contact between the rotating support roller and the material, avoiding the uneven coating caused by the uneven material. At the same time, since the surface of the rotating support roller has a wire groove structure, the friction between the rotating support roller and the material is increased, which effectively prevents the rotating support roller from slipping during the floating process, ensuring the accuracy and clarity of the transfer.

[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0017] Please refer to Figures 1 to 3 As shown, a coating machine of the present invention comprises a frame 1, on which a liquid medicine tank 2, a driving shaft 3, a water passing shaft 4, a transfer roller 5, a damping rod 7 and a floating block 71 are arranged; The driving shaft 3, the water-passing shaft 4 and the transfer roller 5 are all rotatably connected to the frame 1. The driving shaft 3 is respectively connected to the water-passing shaft 4 and the transfer roller 5 through a transmission assembly 6. The surface of the water-passing shaft 4 is respectively in contact with the surface of the driving shaft 3 and the surface of the transfer roller 5. The water-passing shaft 4 is in contact with the medicine in the medicine tank 2. The damping rod 7 is connected to a floating block 71, and a rotating support roller 73 is provided on the floating block 71; The surfaces of the driving shaft 3, the water-passing shaft 4 and the rotating support roller 73 are all provided with wire grooves 31; The transfer roller 5 has a water absorbing layer 51 on its surface.

[0018] From the above description, it can be seen that the beneficial effects of the present invention are: a coating machine, the medicine tank 2 is used to store medicine, and the water-passing shaft 4 is immersed in the water tank. Since its surface has a wire groove 31, the ability to carry medicine is improved, and the medicine at the bottom of the medicine tank 2 can be efficiently brought up and attached to the surface, which not only realizes the recycling of medicine, but also significantly improves efficiency. The active shaft 3 and the water-passing shaft 4 complement each other, and the wire groove 31 is also processed on their surface, which not only enhances the driving effect of the medicine, but also effectively recycles the excess medicine. The excess medicine can be guided and recycled in conjunction with the circulation system to avoid the waste of medicine. The surface of the transfer roller 5 is provided with a water-absorbing layer 51, which makes it have water-absorbing properties and a certain elasticity. Whether it is a flat material or a material with a complex contour, the transfer roller 5 can fit closely with it to achieve a processing effect without dead ends, greatly improving the processing efficiency. The thoroughness and efficiency of the invention is improved. The rotating support roller 73 is installed on the frame through the floating block 71. The floating block 71 can be lifted and lowered by the damping rod 7. When the material passes through the rotating support roller 73, the rotating support roller 73 will float up and down according to the different heights and layers of the material surface, thereby ensuring the close contact between the rotating support roller 73 and the material, avoiding the uneven coating phenomenon caused by the uneven material. At the same time, since the surface of the rotating support roller 73 has a wire groove 31 structure, the friction between the rotating support roller 73 and the material is increased, effectively preventing the rotating support roller 73 from slipping during the floating process, ensuring the accuracy and clarity of the transfer. The floating support device not only improves the coating effect, but also greatly enhances the flexibility and adaptability of the equipment, so that it can cope with a variety of different materials and coating requirements. The coating machine provided by the present invention not only solves the problem of uneven coating of the medicine, but also improves production efficiency while ensuring quality, and reduces the waste of medicine, which is energy-saving and environmentally friendly.

[0019] In an optional embodiment, the wire groove 31 on the surface of the driving shaft 3 is arranged in a spiral shape.

[0020] From the above description, it can be seen that the advantage of the spiral design of the wire groove 31 on the surface of the driving shaft 3 is that it can maximize the water carrying capacity and efficiently bring the medicine at the bottom of the medicine tank 2, which not only realizes the recycling of the medicine, but also significantly improves the efficiency.

[0021] In an optional embodiment, the wire grooves 31 on the surface of the water-passing shaft 4 are arranged in a mesh shape.

[0022] From the above description, it can be seen that the advantage of the mesh design of the lines on the surface of the water-passing shaft 4 is that it not only enhances the driving effect of the medicine, but also effectively recovers the excess medicine and guides it back to the circulation system, avoiding the waste of medicine.

[0023] In an optional embodiment, the wire grooves 31 on the surface of the rotating support roller 73 are arranged in a mesh shape.

[0024] From the above description, it can be seen that the surface of the rotating support roller 73 adopts a mesh processing method, which greatly increases the friction between the roller and the material, effectively prevents the material from slipping during the transfer process, and ensures the accuracy and clarity of the transfer.

[0025] In an optional embodiment, a guide rail 72 is provided on the frame, and the floating block 71 is slidably connected to the guide rail 72 .

[0026] From the above description, it can be seen that the floating block 71 is an important supporting structure of the rotating support roller 73. Its stability and precision are crucial to ensure the parallel operation of the roller. The floating block 71 is made of high-strength material to ensure the stability of the rotating support roller 73 during high-speed operation. Through precise manufacturing technology and strict testing procedures, the parallelism of the rotating support roller 73 after installation is ensured, thereby avoiding the deviation of the rotating support roller 73 during operation and ensuring the accuracy of the transfer and coating effects. The guide rail 72 is a linear slide rail, which is a key component in the equipment to achieve precise positioning and smooth sliding. Through the precise slide rail combination design, the stability and precision of the roller fixing seat during the sliding process are ensured. This high-precision slide rail not only has excellent wear resistance, but also can maintain smooth sliding during long-term operation, reducing wear and noise caused by friction, thereby extending the service life of the equipment.

[0027] In an optional embodiment, the surfaces of the driving shaft 3, the water passing shaft 4 and the rotating support roller 73 are all provided with a corrosion-resistant Teflon layer.

[0028] From the above description, it can be seen that the corrosion-resistant Teflon layer can not only effectively resist the erosion of various corrosive substances, but also has excellent wear resistance, ensuring the stability and durability of the roller in long-term operation.

[0029] In an optional embodiment, a hexagonal shaft 52 is provided at one end of the transfer roller 5 , and a quick-release knob 53 connected to the frame 1 is provided at the other end of the transfer roller 5 .

[0030] From the above description, it can be seen that the design of the hexagonal shaft 52 fully considers the convenience of equipment maintenance. The end of the transfer roller 5 is in a hexagonal form, which makes it easy to complete the installation or removal process, greatly shortening the maintenance time. When the lower roller needs to be repaired or replaced, the user only needs to simply rotate the knob to easily pull out the axis and complete the removal of the lower roller. The whole process does not require complicated tools, which greatly simplifies the operation process and improves work efficiency.

[0031] In an optional embodiment, the water-absorbing layer 51 is a PP water-absorbing sponge layer.

[0032] From the above description, it can be seen that the PP water-absorbing sponge layer not only ensures the roller's resistance to a variety of corrosive substances, but also gives it good elasticity and water absorption properties.

[0033] In an alternative embodiment, the damping rod 7 is a cylinder.

[0034] From the above description, it can be seen that the damping rod 7 adopts a cylinder as an adaptive adjustment component in the equipment. Its function is to pull the floating block 71 to achieve high adaptation between the roller and the material. When the material passes through the roller, the cylinder will float up and down according to the different high and low layers on the surface of the material, thereby ensuring the close contact between the rotating support roller 73 and the material, avoiding uneven coating caused by uneven materials. This design not only improves the coating effect, but also greatly enhances the flexibility and adaptability of the equipment, enabling it to cope with a variety of different materials and coating requirements.

[0035] In an optional embodiment, the transmission assembly 6 is a pulley transmission assembly 6 .

[0036] From the above description, it can be known that the driving wheel drives the water flow shaft 4 and the transfer roller 5 to rotate respectively through the cooperation of the belt and the three transmission wheels.
