Description

Technical Field

[0001] The invention relates to the technical field of diaphragm production equipment, and in particular to a diaphragm spraying production line. Background Art

[0002] The spraying process is widely used in the coating of flexible diaphragms. The design of existing diaphragm spraying production lines is as follows: Figure 1 As shown, the diaphragm passes through one side of the output end of the spraying device from bottom to top, so that the mist slurry adheres to the surface of the diaphragm. This belt-feeding method will cause the mist slurry to be driven upward by the movement of the diaphragm. If a material receiving device is installed above the sprayer, the mist slurry will condense on the surface of the material receiving device and drip onto the surface of the diaphragm, causing water droplet-shaped defects on the diaphragm, affecting the quality rate of the diaphragm spraying product; at the same time, the mist slurry will freely disperse after going up, causing workshop environmental pollution, health threats to personnel and waste of slurry; in addition, in order to achieve coating on the same side of the diaphragm, it is necessary to add a flip rack to flip the diaphragm, but the use of a flip rack will affect the flatness of the diaphragm, and then affect the uniformity of the diaphragm. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a diaphragm spraying production line, which can prevent the mist slurry from condensing and dripping onto the diaphragm surface, thereby avoiding the appearance of water droplet-shaped defects on the diaphragm, and can recycle the mist slurry to prevent it from being freely dispersed, and can achieve coating on the same side of the diaphragm without the need for an additional turning frame.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A diaphragm spraying production line comprises an unwinding mechanism, a coating mechanism, an oven and a winding mechanism, wherein the coating mechanism comprises a roller coating mechanism and a spraying mechanism for coating slurry on the same side of the diaphragm, the unwinding mechanism and the winding mechanism are arranged on the same side of the oven, the roller coating mechanism and the spraying mechanism are respectively arranged on both sides of the oven, the roller coating mechanism is arranged between the unwinding mechanism and the oven, the spraying mechanism comprises a spraying device and a spraying guide roller for unfolding the diaphragm, the spraying guide roller comprises an upper guide roller and a lower guide roller arranged up and down, a receiving trough for recovering mist slurry is arranged below the spraying device, when working, the diaphragm is unwound from the unwinding mechanism and passes through the roller coating mechanism, the oven, the side of the upper guide roller facing the spraying device, the side of the lower guide roller facing the spraying device and the oven in sequence to reach the winding mechanism.

[0006] As a preferred solution, the diaphragm between the roller and the lower guide roller is inclined from top to bottom away from the spraying device.

[0007] As a preferred solution, a traction mechanism is provided between the unwinding mechanism and the roller coating mechanism.

[0008] As a preferred solution, a winding guide roller group for guiding the diaphragm is provided between the winding mechanism and the oven.

[0009] As a preferred solution, an inner guide roller for unfolding the membrane after roller coating is provided in the oven, and outer guide rollers for unfolding the membrane after spray coating are provided on both sides of the oven.

[0010] As a preferred embodiment, a roller coating baking channel and a spray coating baking channel are provided in the oven, the roller coating baking channel is located above the spray coating baking channel, the inner guide roller is arranged in the roller coating baking channel, and the outer guide roller is arranged on both sides of the spray coating baking channel.

[0011] As a preferred solution, the material receiving trough has an upward opening, and the lower guide roller is located above the opening of the material receiving trough.

[0012] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically,

[0013] 1. By setting an unwinding mechanism, a coating mechanism, an oven and a winding mechanism, the coating mechanism includes a roller coating mechanism and a spraying mechanism for coating the slurry on the same side of the diaphragm, the unwinding mechanism and the winding mechanism are arranged on the same side of the oven, the roller coating mechanism and the spraying mechanism are respectively arranged on both sides of the oven, the roller coating mechanism is arranged between the unwinding mechanism and the oven, the spraying mechanism includes a spraying device and a spraying guide roller for unfolding the diaphragm, the spraying guide roller includes an upper guide roller and a lower guide roller arranged up and down, and a receiving trough for recovering the mist slurry is arranged below the spraying device. When working, the diaphragm is released from the unwinding mechanism and passes through the roller coating mechanism, the oven, the side of the upper guide roller facing the spraying device, the side of the lower guide roller facing the spraying device and the oven to reach the winding mechanism, so that the mist slurry is driven downward by the movement of the diaphragm to avoid the mist slurry condensing and dripping onto the surface of the diaphragm, thereby avoiding the appearance of water drop-shaped defects on the diaphragm. The receiving trough can recover the mist slurry to avoid the free dissipation of the mist slurry.

[0014] 2. The diaphragm between the upper guide roller and the lower guide roller is tilted from top to bottom away from the spraying device, so that the mist slurry is sprayed onto the diaphragm surface at an inclined angle. The mist slurry not attached to the diaphragm is subjected to the downward reaction force of the diaphragm, so that the mist slurry has a tendency to move downward.

[0015] 3. The same side of the diaphragm can be coated without setting up an additional flip frame, avoiding the influence of the flip frame on the flatness of the diaphragm and improving the uniformity of the diaphragm coating.
