DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figures 1-12 An embodiment of the present invention provides a non-woven fabric coating machine, comprising a dipping tank 10 for storing a coating and a coating roller 13 rotatably connected thereto. The base fabric is conveyed by a conveying mechanism of the coating machine. The coating is stored in the dipping tank 10. A portion of the coating roller 13 is immersed in the dipping tank 10, and another portion of the coating roller 13 is in contact with the base fabric. The coating is transferred to the fabric surface by the coating roller 13. A drive motor is provided outside the dipping tank 10, and the coating roller 13 is connected to the coating roller 13 via the output shaft of the drive motor to drive the coating roller 13. The machine further comprises:

[0037] The material balancing mechanism 12 installed in the dipping tank 10 includes a track rod 121 and a swinging member, and the swinging member is slidably arranged on the track rod 121; the swinging member is displaced along the track rod 121, and when the swinging member moves, the paint in the dipping tank 10 can be driven to move, so that the paint in the dipping tank 10 moves fully, ensuring the consistency of the paint temperature at various locations in the dipping tank 10, so that the temperature sensor is more accurate when detecting the paint temperature in the dipping tank 10; in an embodiment of the present invention, the swinging member includes a central shaft 122, an arc piece 123, a telescopic piece 124, a moving rod 125, a top block 126, an elastic member 127 and a cam 128, the central shaft 122 is slidably connected to the track rod 121, the arc piece 123 is rotatably connected to the central shaft 122, the cam 128 is fixedly installed on the central shaft 122, the moving rod 125 is slidably inserted into the arc piece 123, the telescopic piece 12 4 is fixedly mounted on one end of the moving rod 125, the other end of the arc-shaped piece 123 abuts against the cam 128, the top block 126 is mounted on the moving rod 125, and one end of the elastic member 127 abuts against the lower surface of the top block 126; the central shaft 122 is sleeved on the track rod 121, and when the central shaft 122 is subjected to a force along the length direction of the track rod 121, the central shaft 122 will be displaced along the length direction of the track rod 121, and the driving part 14 drives the arc-shaped piece 123 to continuously move back and forth along the length direction of the track rod 121, so that the arc-shaped piece 123 repeatedly approaches the coating roller 13 and then moves away from the coating roller 13. In this way, during this reciprocating motion, the arc-shaped piece 123 drives the paint inside the dipping tank 10 to move, so that the paint in different areas of the dipping tank 10 is fully mixed, ensuring that the temperature sensor detects the paint in the dipping tank 10 more accurately;

[0038] The driving part 14 is used for driving the swing piece to reciprocate along the track rod 121, the swing piece has a first stroke and a second stroke, and the swing piece is switched between the first stroke and the second stroke in the driving process of the driving part 14; through the driving of the driving part 14, the swing piece reciprocates ceaselessly, in the first stroke, the driving part 14 drives the swing piece to be close to the position where the coating roller 13 is located, the output end of the driving part 14 extrudes the arc-shaped sheet 123, when the arc-shaped sheet 123 is extruded, the arc-shaped sheet 123 is turned around the center shaft 122 as the center, the arc-shaped sheet 123 rotates counterclockwise, the lowest point of the arc-shaped sheet 123 is close to the inner wall of the immersion tank 10, and because of the rotation of the arc-shaped sheet 123, the moving rod 125 also rotates, and one end of the moving rod 125 abuts against the cam 128; in the rotating process of the moving rod 125, the position of the end of the moving rod 125 on the cam 128 changes, and the contact position gradually moves to the lowest point of the cam 128; in the moving process, compared with the arc-shaped sheet 123, the moving rod 125 moves downward, so that the telescopic sheet 124 moves downward synchronously, the telescopic sheet 124 extends out of the arc-shaped sheet 123, and in the continuous swinging of the arc-shaped sheet 123, the telescopic sheet 124 continuously extends out, and in the final position, the telescopic sheet 124 is attached to the bottom of the inner wall of the immersion tank 10; at this time, the driving part 14 continuously applies a pushing force to the arc-shaped sheet 123, and the angle of the arc-shaped sheet 123 moves to a position where the arc-shaped sheet 123 cannot continue to rotate, so that the driving part 14 drives the center shaft 122 to displace along the track rod 121, so that the arc-shaped sheet 123 and the telescopic sheet 124 displace towards the coating roller 13; in another embodiment, the arc-shaped sheet 123 is provided with a circulating port 129, and as the arc-shaped sheet 123 and the telescopic sheet 124 displace towards the coating roller 13, the coating in the immersion tank 10 is driven towards the coating roller 13, so that the arc-shaped sheet 123 is a separation, in the first stroke, the coating is driven to one side of the immersion tank 10 close to the coating roller 13, at this time, the coating in the immersion tank 10 is unbalanced, and the coating on the side close to the coating roller 13 is returned to the area where the coating in the immersion tank 10 is less through the circulating port 129; in the second stroke, the output end of the driving part 14 is retracted, at this time, the driving part 14 pulls the arc-shaped sheet 123 to rotate back, in the rotating-back process of the arc-shaped sheet 123, the end of the moving rod 125 gradually separates from the lowest point of the cam 128, in the separating process, the elastic piece 127 is subjected to the action of the elastic force of itself, applies a pushing force to the top block 126, and drives the moving rod 125 to move upwards, so that in the rotating-back process of the arc-shaped sheet 123, the telescopic sheet 124 is passively retracted into the arc-shaped sheet 123 synchronously, after the arc-shaped sheet 123 rotates back, under the continuous pulling of the driving part 14, when the pulling force on the center shaft 122 is greater than the frictional force between the center shaft 122 and the track rod 121, the center shaft 122 is reset along the track rod 121, in the resetting process, the bottom of the arc-shaped sheet 123 does not separate from the coating in the immersion tank 10,When retracting, since the arc-shaped piece 123 is in the upper layer of the paint, the arc-shaped piece 123 drives the upper layer of the paint to move away from the coating roller 13 to the direction of the dipping tank 10, and flows into the area, the paint increases, in order to ensure the liquid level balance, the lower layer of the paint in the area flows to the direction close to the coating roller 13, so that through the movement of the first stroke and the second stroke, the paint in different areas can be fully mixed, and the detection temperature of the temperature sensor when detecting the paint in the dipping tank 10 is more accurate.

[0039] The linkage mechanism 15 is drivingly connected between the driving part 14 and the coating roller 13, when the coating roller 13 rotates, the material uniformizing mechanism 12 receives the driving of the driving part 14 to drive the paint in the dipping tank 10 to move. Under the linkage of the linkage mechanism 15, the power when the coating roller 13 rotates can be converted into the power source of the driving part 14, and the material uniformizing mechanism 12 is driven to move through the driving part 14, so as to drive the paint in the dipping tank 10 to move, so that the paint in different areas of the dipping tank 10 is mixed correspondingly, so that the temperature of the paint in the dipping tank 10 is uniform, which improves the accuracy of the temperature sensor when detecting the temperature of the paint in the dipping tank 10. By using the linkage mechanism 15 and the driving part 14, the material uniformizing mechanism 12 can be driven to move without using electromechanical equipment, which reduces the use of electromechanical equipment, saves cost and has high stability.

In an embodiment, in use, a part of the coating can be attached to the paddle 167, the paddle 167 is driven to rotate by the roller 166, the paddle 167 is hinged on the roller 166, when the paddle 167 rotates to the position of the pressure strip 168, the pressure strip 168 hinders the rotation of the paddle 167, and the paddle 167 rotates at an angle, when rotating, the paddle 167 extrudes the V-shaped piece 169, the V-shaped piece 169 deforms, and an opposite force is applied to the paddle 167, and in the continuous process, the paddle 167 is separated from the pressure strip 168, the paddle 167 is reset under the action of the resilience of the V-shaped piece 169, and at this time, the roller 166 drives the paddle 167 to move to the position of the next pressure strip 168, so that the paddle 167 collides with the next pressure strip 168 in the resetting process, and a certain vibration is generated, so that the residual coating is separated from the paddle 167. It should be noted that, in order to avoid the influence of vibration on the coating roller 13, the scraping blade 163 is made of nylon or silica gel, the scraping blade 163 is in sliding fit, and the contact is a linear joint, so as to maximize the influence of vibration on the coating roller 13.

[0046] The pressure strip 168 is in the circumferential movement path of the paddle 167, and a liquid leakage groove 1681 is formed in the pressure strip 168. Since the paddle 167 is in a state of movement, the coating on the pressure strip 168 is continuously scraped upward by the paddle 167 when falling downward, and therefore, in order to ensure that the coating on the pressure strip 168 falls smoothly, the liquid leakage groove 1681 lower than the pressure strip 168 is formed, so as to ensure that the coating falls into the material box 165 smoothly.

[0047] One side of the V-shaped piece 169 is provided with a contact surface 1692 abutting against the outside of the paddle 167, and a collapse opening 1691 is formed in the bending part of the V-shaped piece 169. The contact surface 1692 is arranged to ensure that the V-shaped piece 169 and the paddle 167 have sufficient contact surface, so that the abutment of the V-shaped piece 169 and the paddle 167 is more stable, and when the V-shaped piece 169 deforms, the collapse opening 1691 collapses to ensure the smooth deformation of the V-shaped piece 169, avoid excessive resilience, the more the number and the larger the size of the collapse opening 1691, the smaller the force required for the deformation of the V-shaped piece 169, and the smaller the resilience, and the corresponding collapse opening 1691 is formed according to the actual material.

[0048] The linkage mechanism 15 comprises pulleys 151 and belts 152, the pulleys 151 are installed on the roller 166, the coating roller 13 and the transmission shaft 141, the pulleys 151 are connected by the belts 152, and the linkage between the roller 166 and the coating roller 13 and the linkage between the coating roller 13 and the transmission shaft 141 can be realized by the linkage mechanism 15. In this way, the coating roller 13 is used as a power source, and the use of electromechanical equipment is reduced.

[0049] The above merely describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
