DETAILED DESCRIPTION

[0020] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0021] like Figure 1-2 As shown, a new type of double-sided adjustable metering coating equipment includes a base 1, which is a frame structure. A metering coating component is fixedly arranged on the top of the base 1, and a lifting mechanism 2 is arranged based on the base 1. The liquid tank 3 is located in the lifting mechanism 2, that is, the liquid tank 3 is driven by the lifting mechanism 2 to reciprocate along the height direction of the base 1.

[0022] The lifting mechanism 2 is described in detail below. A through hole adapted to the vertical rod of the base 1 is opened at the edge of the liquid tank 3, so that the liquid tank 3 can reciprocate along the radial direction of the vertical rod, and then the liquid tank 3 is lifted and lowered by a screw rod or a cylinder at the edge of the liquid tank 3, thereby completing the reciprocating motion of the liquid tank 3 along the height direction of the base 1.

[0023] like Figure 3 As shown, the metering coating assembly is described in detail below. The metering coating assembly includes a frame 4 fixedly arranged on the top of the base 1, a first metering roller 5, a second metering roller 6 and a supporting idler roller 7 are rotatably fixed in the frame 4, a scraper 11 assembly is fixedly arranged close to the first metering roller 5 and the second metering roller 6, and the first metering roller 5 and the second metering roller 6 are driven by a transmission mechanism, which is arranged on the outer side of the frame 4.

[0024] A moving assembly is arranged on the frame 4, and the moving assembly includes slide grooves correspondingly opened on both sides of the frame 4 and a movable plate 8 that can reciprocate along the slide groove direction. The two ends of the first metering roller 5 are respectively movably fixed on the movable plate 8, and the first metering roller 5 and the movable plate 8 can be fixed by bearings. Cylinders are also arranged on the two side surfaces of the frame 4, and the telescopic rods of the cylinders face the direction in which the first metering roller 5 is away from the second metering roller 6, and the ends of the telescopic rods are fixed on the movable plate 8. Because the two ends of the first metering roller 5 are respectively fixed on the movable plates 8 on both sides of the frame 4, and the telescopic rods of the cylinders are fixed to the movable plates 8, when the cylinders move, the movable plates 8 can be pushed out, and the telescopic rods of the two cylinders face the direction in which the first metering roller 5 is away from the second metering roller 6, then when the telescopic rods of the cylinders are extended, the first metering roller 5 gradually moves away from the second metering roller 6.

[0025] The transmission mechanism is described in detail below. The transmission mechanism includes a second transmission mechanism for driving the second metering roller 6 and a first transmission mechanism for driving the first transmission roller.

[0026] Based on the above content, it can be known that the second metering roller 6 is set at a fixed position on the frame 4, and the second metering roller 6 does not have the property of changing its position on the frame 4, so the second transmission mechanism is first described in terms of structure. The second transmission mechanism includes a second motor 17, the second motor 17 is connected to a second reducer 18, a second driving wheel is coaxially fixed on the second reducer 18, a second synchronous pulley 19 is coaxially fixed on the second metering roller 6 facing one end of the second transmission mechanism, and the second driving wheel and the synchronous pulley are linked by a synchronous belt 20. When the motor is working, after the second reducer 18 completes the change of direction, the second driving wheel cooperates with the synchronous belt 20, and the synchronous belt 20 drives the second synchronous pulley 19, thereby driving the second metering roller 6 to complete the rotation.

[0027] The first transmission mechanism includes a first motor 13, the first motor 13 is connected to a first reducer 14, a first driving wheel is coaxially fixed on the first reducer 14, a first synchronous pulley 15 is fixed to the end of the first metering roller 5 facing the first transmission mechanism, the first driving wheel and the first synchronous pulley 15 are linked by a synchronous belt 20, the driving mode of the first motor 13 for the first metering roller 5 is the same as the driving mode of the second transmission device for the second metering roller 6, and the utility model will not be repeated here.

[0028] The difference between the first transmission mechanism and the second transmission mechanism is that the first metering roller 5 driven by the first transmission mechanism is arranged on the aforementioned moving component, and its position is not arranged on a fixed position of the frame 4 like the second metering roller 6, so it is necessary to consider the driving method when it is displaced. Therefore, in the utility model, a tensioning structure is added on the basis of the aforementioned first transmission mechanism. The tensioning structure is arranged close to the first transmission mechanism, including a tensioning wheel and a tensioning cylinder 16 arranged between the tensioning wheel and the first reducer 14. A roller is movably fixed at the end of the telescopic rod of the tensioning cylinder 16. The first driving wheel, the first synchronous pulley 15 and the tensioning wheel are linked with the synchronous belt 20. However, due to the horizontal movable characteristic of the first metering roller 5, the tensioning condition of the synchronous belt 20 is adjusted by the tensioning cylinder 16. The roller at the end of the telescopic rod of the aforementioned cylinder is against the synchronous belt 20. Through the control of the cylinder, the thrust added by the roller to the synchronous belt 20 can be controlled, and the existence of the roller does not affect the movement of the synchronous belt 20. In this way, the synchronous belt 20 can adapt to multiple positions of the first metering roller 5, thereby ensuring the driving of the first metering roller 5 by the first transmission mechanism.

[0029] The scraper 11 assembly is described below. The number of scraper 11 assemblies is the same as the number of metering rollers. The scraper 11 assembly is fixedly arranged under the first metering roller 5 and the second metering roller 6, and includes a cylinder and a scraper 11. The telescopic rod of the cylinder is vertically arranged in the frame 4 facing the first metering roller 5 or the second metering roller 6. The scraper 11 is fixedly arranged at an angle at the end of the telescopic rod. The end of the scraper 11 is close to the surface of the first metering roller 5 or the second metering roller 6. A baffle plate 12 is fixedly arranged close to the contact end of the scraper 11 and the metering roller. The baffle plate 12 is arranged obliquely downward. Pressure is applied to the scraper 11 by the cylinder so that the scraper 11 is pressed against the roller surface. A baffle plate 12 is arranged, and the scraped liquid can return to the immersion tank through the baffle plate 12.

[0030] A track is fixedly arranged at the top of the base 1 along its length direction, and a plurality of wheels are arranged at the bottom of the frame 4, and the plurality of wheels match the track. That is, the wheels arranged at the bottom of the frame 4 can move along the length direction of the track on the top of the base 1 to adjust the position of the frame 4 on the upper surface of the base 1. It is worth noting that a clutch 10 is used to connect the first metering roller 5 and the first transmission device and the second metering roller 6 and the second transmission device, that is, when the frame 4 is away from the transmission mechanism, the clutch 10 is separated, and the first metering roller 5 and the second metering roller 6 can be cleaned and replaced. After completion, the frame 4 is brought close to the transmission mechanism again, and the clutch 10 is engaged, and the double-sided coating process can be carried out again.

[0031] Based on the fact that a dipping idler roller 9 is fixedly arranged at the bottom of the frame 4, and the distance from the dipping idler roller 9 to the top of the frame 4 is smaller than the maximum depth of the liquid tank 3, when the liquid tank 3 rises to the corresponding position under the action of the lifting mechanism 2, the dipping idler roller 9 can be located in the liquid tank 3 and will not touch the edge of the liquid tank 3. When the material film passes through the dipping idler roller 9, it will not touch the edge of the liquid tank 3, thereby avoiding damage to the material film.

[0032] A moving wheel is fixedly provided at the bottom of the frame 4, and the moving wheel matches the track located on the ground. The setting of this part is the same as the track and roller set on the base 1 mentioned above, and the utility model will not be repeated here. By cooperating with the track and the moving wheel, the entire double-sided adjustable metering coating equipment can be transferred.

[0033] During specific use, the material film enters along the supporting idle roller 7 in a clockwise direction, passes through the material liquid tank 3 in a counterclockwise direction through the self-impregnated idle roller 9, and completes the double-sided coating after the first metering roller 5 and the second metering roller 6 realize online control of the double-sided coating thickness, and then enters a flotation oven for drying.

[0034] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
