Technical Field
[0001] This utility model relates to the field of coating machines, and in particular to a coating machine with tension adjustment function. Background Technology
[0002] The working principle of a coating machine is mainly to evenly apply adhesives, coatings, or inks onto a substrate through a coating head, and then cure the coating through a drying device. Coating machines are commonly used in the surface coating process of materials such as films and paper. Their basic structure includes a coating head, a winding and unwinding mechanism, and a tension control system.
[0003] After the substrate is coated, the finished substrate needs to be wound up for storage to facilitate subsequent transportation. However, because the substrate is long, dust and impurities in the air can easily adhere to the substrate during winding, causing pollution.
[0004] Therefore, it is necessary to propose a new coating machine with tension adjustment function to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a coating machine with tension adjustment function to solve the problem that after the substrate is coated, it is necessary to wind the finished substrate for storage to facilitate subsequent transportation. However, because the substrate is long, dust and impurities in the air can easily adhere to the substrate during winding, causing pollution.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a coating machine with tension adjustment function, comprising a support frame, wherein shaft retainers are fixed on both sides inside the support frame, a winding roller is rotatably connected between the two shaft retainers, two bases are provided on one side of the support frame, the two bases are distributed parallel to each other along the length of the support frame, and a cylinder is fixed at the top of the two bases, a connecting seat is provided at the top of the two cylinders, and a support roller is rotatably connected between the two connecting seats;
[0007] The support roller has multiple protruding ends fixed around its outer side, which are distributed along the length of the support roller. The support roller has a cavity inside, and a first suction pump is fixed to one end of the support roller. The first suction pump is connected to the cavity. Each of the multiple protruding ends has an adsorption port on the side away from the support roller, and the adsorption ports are connected to the cavity.
[0008] Preferably, a connecting frame is fixed between the top ends of the two shaft retainers, a spring telescopic rod is fixed inside the top end of the connecting frame, a pressure block is fixed at the bottom end of the spring telescopic rod, and a substrate is transferred between the support roller and the winding roller.
[0009] Preferably, the lower pressure block and the winding roller have the same length, and their positions correspond.
[0010] Preferably, a second suction pump is fixedly connected to the top of the connecting frame, an air chamber is opened inside the lower pressure block, an adsorption groove is opened at the bottom of the lower pressure block along the length direction, the adsorption groove and the air chamber are connected in communication, and an air pipe is connected to the bottom of the second suction pump, the bottom of the air pipe and the air chamber are connected in communication.
[0011] Preferably, a drive motor is fixed on one side of the support frame, and the drive shaft of the drive motor is connected to the end of the winding roller.
[0012] Preferably, the lower half of the pressing block is configured as an arc surface.
[0013] Preferably, the winding roller and the support roller have the same length.
[0014] The technical advantages of this utility model are as follows:
[0015] When the substrate moves, its lower surface comes into contact with the suction port on the support roller. After the first suction pump starts, it can adsorb dust and impurities on the lower surface of the substrate through the suction port to complete the cleaning task. At the same time, as the substrate moves, its lower surface rubs against multiple protruding ends, causing the support roller to rotate. This allows different suction ports to come into contact with the lower surface of the substrate, preventing one of the suction ports from becoming blocked and unable to continue the cleaning task. In addition, multiple protruding ends increase the contact area with the substrate, increase friction, and increase the contact time between the substrate and the suction port.
[0016] After the winding roller winds the substrate, the spring telescopic rod will drive the lower pressure block to press against the outer surface of the wound substrate in real time, so as to avoid sweeping of the wound substrate on the winding roller. As the thickness of the wound substrate increases, it can automatically adapt. After the lower pressure block presses against the outer surface of the substrate, the second suction pump can be started so that the adsorption tank can absorb the dust and impurities on the outer surface of the substrate. Together with the support roller, the dust removal work of the entire upper and lower surfaces of the substrate is completed. Attached Figure Description

[0021] like Figure 1 - Figure 3 The present invention provides a coating machine with adjustable tension, including a support frame 1. Shaft retainers 3 are fixed on both sides inside the support frame 1. A winding roller 2 is rotatably connected between the two shaft retainers 3. A drive motor 4 is fixed on one side of the support frame 1. The drive shaft of the drive motor 4 is connected to the end of the winding roller 2. The support frame 1 can support the drive motor 4 and the winding roller 2. When the drive motor 4 is started, it can drive the winding roller 2 to rotate, thereby realizing the winding operation.
[0022] Two bases 6 are provided on one side of the support frame 1. The two bases 6 are distributed parallel to each other along the length of the support frame 1, and cylinders 7 are fixed at the top of the two bases 6. Connecting seats are provided at the top of the two cylinders 7. Support rollers 8 are rotatably connected between the two connecting seats. Substrate 10 is transferred between support rollers 8 and winding rollers 2.
[0023] One end of the substrate 10 is connected to the winding roller 2. The winding roller 2 rotates to drive the substrate 10 to wind. When the substrate 10 moves, the support roller 8 can support the substrate 10 during winding. When the cylinder 7 extends upward, it will drive the corresponding connecting seat to rise, that is, the support roller 8 will rise. Since the support roller 8 is supported on the lower surface of the substrate 10, when the support roller 8 is raised, it will press against the substrate 10 to complete the tension, so as to prevent the substrate 10 from loosening or sinking during winding.
[0024] A connecting frame 13 is fixed between the top ends of the two shaft retainers 3. A spring telescopic rod 14 is fixed at the top end inside the connecting frame 13. A lower pressure block 15 is fixed at the bottom end of the spring telescopic rod 14. Multiple protruding ends 11 are fixed around the outside of the support roller 8. The multiple protruding ends 11 are distributed along the length direction of the support roller 8. A cavity is opened inside the support roller 8. A first suction pump 9 is fixed at one end of the support roller 8. The first suction pump 9 is connected to the cavity. An adsorption port 12 is opened on the side of the multiple protruding ends 11 away from the support roller 8. The multiple adsorption ports 12 are connected to the cavity.
[0025] In the actual operation of this utility model, when the substrate 10 is moving, the lower surface of the substrate 10 will contact the adsorption port 12 on the support roller 8. After the first suction pump 9 is started, it can adsorb the dust and impurities on the lower surface of the substrate 10 through the adsorption port 12 to complete the cleaning task. At the same time, when the substrate 10 moves, the lower surface of the substrate 10 will rub against multiple protruding ends 11, causing the support roller 8 to rotate, so that different adsorption ports 12 contact the lower surface of the substrate 10, avoiding one adsorption port 12 from becoming blocked and unable to continue to complete the cleaning task. At the same time, multiple protruding ends 11 increase the contact area with the substrate 10, increase the friction, and increase the contact time between the substrate 10 and the adsorption port 12.
[0026] The lower pressure block 15 and the winding roller 2 have the same length, and their positions correspond.
[0027] The top of the connecting frame 13 is fixedly connected to the second suction pump 17. The lower pressure block 15 has an air chamber inside. The bottom of the lower pressure block 15 has an adsorption groove 16 along the length direction. The adsorption groove 16 is connected to the air chamber. The bottom of the second suction pump 17 is connected to the air pipe 5. The bottom of the air pipe 5 is connected to the air chamber.
[0028] In the actual operation of this utility model, after the winding roller 2 winds the substrate 10, the spring telescopic rod 14 will drive the lower pressure block 15 to press against the outer surface of the wound substrate 10 in real time, so as to avoid sweeping of the wound substrate 10 on the winding roller 2. As the thickness of the wound substrate 10 increases, it can automatically adapt. After the lower pressure block 15 presses against the outer surface of the substrate 10, the second suction pump 17 can be started so that the adsorption tank 16 can absorb the dust and impurities on the outer surface of the substrate 10. Together with the support roller 8, the dust removal work of the entire upper and lower surfaces of the substrate 10 is completed.
[0029] The lower half of the pressure block 15 is set as an arc surface, and the winding roller 2 and the support roller 8 have the same length.
