Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a coating machine detection device. Background Art

[0002] In the production process of release paper, a coating machine is needed to coat the paper. Existing coating machines need to detect the paper before processing to avoid wrinkles or spots on the paper surface that affect the coating process. Existing coating machines use manual observation, which has a slow detection speed and a high error rate due to manual fatigue during long-term observation.

[0003] The Chinese patent with patent publication number CN209821065U discloses a detection device, which pre-cleans the material with two rollers, and then sets a lighting lamp and a photosensitive component to cooperate. When there is dust, wrinkles, or spots, the transmittance will be changed to make the alarm sound, thereby playing a detection role. However, the above design still has the following problems: if the material is only cleaned by the rollers, if the cleaning is not in place, the number of alarms will be large, and it is necessary to stop the machine after multiple alarms to clean the material, which affects the production efficiency. Therefore, the cleaning effect of only cleaning by the rollers needs to be improved. Therefore, a coating machine detection device is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a coating machine detection device, which has the advantage of not easily giving repeated alarms due to poor cleaning effects.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coating machine detection device, comprising two traction rollers and a detection device, wherein the detection device is placed between the two traction rollers, and a material is transmission-connected between the traction rollers, and the material passes through the detection device, and also comprises a cleaning mechanism, wherein the cleaning mechanism comprises a fan-shaped gear rotatably arranged on a mounting frame, and a horizontally extending mounting frame is fixed on the detection device, a cleaning assembly is slidably connected to the lower end of the mounting frame, and a through hole is provided on the mounting frame, and a tooth structure is provided at the upper end of the cleaning assembly, and the tooth structure is meshed with the fan-shaped gear through the through hole, so that the cleaning assembly is intermittently driven to slide when the fan-shaped gear rotates, and a spring is connected to either side of the sliding direction of the cleaning assembly.

[0006] Furthermore, it also includes an alarm component, which is electrically connected to the detection device and the traction roller respectively.

[0007] Furthermore, it also includes a tensioning roller, which is lifted and lowered at both ends of the material and respectively abuts against the upper and lower end surfaces of the material.

[0008] Furthermore, the cleaning assembly includes a connecting rod, and a cleaning piece is arranged on the connecting rod.

[0009] Furthermore, the cleaning member is a brush, and the brush is detachably connected to the connecting rod.

[0010] Furthermore, it also includes an adjustment mechanism, which includes a second motor, and the output shaft of the second motor is coaxially connected to a screw with positive and negative threads. The detection device is adapted to be threadedly connected to the screw with positive and negative threads, so that when the screw rotates, the two detection parts of the detection device are driven to move closer and farther.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The coating machine detection device, by setting the cooperation of the tooth structure of the sector gear and the cleaning component, makes it possible for the cleaning component to be moved by the sector gear and, under the action of the spring, the cleaning element to reciprocate rapidly and at high frequency, which is more effective than the roller cleaning effect, reduces the alarm and the shutdown for cleaning due to inadequate cleaning, and improves production efficiency. When there is dust or spots on the surface of the material, the two traction rollers can be reversed to allow the material passing through the detection area to be reset between the upper and lower cleaning elements and cleaned again. The above design does not require shutdown, which further increases production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 1-5A coating machine detection device in the present application includes two traction rollers 1 and a detection device 4, the detection device 4 is placed between the two traction rollers 1, and a material 2 is transmission-connected between the traction rollers 1, and the material 2 passes through the detection device 4, and also includes a cleaning mechanism, the cleaning mechanism includes a fan gear 51 rotatably arranged on a mounting frame 44, a horizontally extending mounting frame 44 is fixed on the detection device 4, a cleaning component is slidably connected to the lower end of the mounting frame 44, and a through hole 442 is opened on the mounting frame 44, a tooth structure is provided at the upper end of the cleaning component, and the tooth structure is meshed with the fan gear 51 through the through hole 442, so that the fan gear 51 intermittently drives the cleaning component to slide when it rotates, and a spring 53 is connected to either side of the sliding direction of the cleaning component.

[0021] The device is provided with a toothed structure above the cleaning component, and a through hole 442 is opened on the mounting frame 44, so that the fan gear 51 located above the mounting frame 44 can pass through the through hole 442 and cooperate with the toothed structure for transmission. Therefore, when the motor 5 drives the fan gear 51 to rotate, the fan gear 51 can intermittently mesh with the toothed structure below the mounting frame 44, and cooperate with the reset effect of the spring 53 to realize the reciprocating oscillation of the cleaning component. Compared with the roller cleaning the material 2 under the friction between the roller and the material 2, this design has a better cleaning effect, avoids the situation of alarm and shutdown for cleaning due to inadequate cleaning, and increases production efficiency.

[0022] Furthermore, an alarm component is included, and the alarm component is electrically connected to the detection device 4 and the traction roller 1 respectively.

[0023] The alarm component usually includes a PLC controller and a buzzer or a warning light and other components for warning. The detection device 4 can adopt the technical solution disclosed in the Chinese patent with publication number CN209821065U. Through the cooperation of the photosensitive original and the lighting lamp 41, when the lighting lamp 41 irradiates the material 2, if there is dust or spots on the material 2, the light transmittance can be changed, so that it can be detected by the photosensitive element 42. The above two mechanisms are both existing technologies and will not be repeated here.

[0024] The device can electrically connect the alarm component with the detection device 4, so that when the detection device 4 detects that there is a problem with the material 2, it can promptly remind the user. At the same time, the detection device 4 is electrically connected to the PLC controller and the traction roller 1, so that when it is detected that the material 2 has spots or dust, the detection device 4 can send an electrical signal to the PLC controller, and the PLC controller controls the traction roller 1 to reverse, so that the cleaned material 2 is reset between the cleaning components to achieve the effect of re-cleaning. This design can automatically clean the material 2 without stopping when the material 2 is not cleaned, thereby increasing production efficiency, and the duration of repeated cleaning can be pre-set by the PLC controller.

[0025] Furthermore, it also includes a tensioning roller 3, which is lifted and lowered at both ends of the material 2 and abuts against the upper and lower end surfaces of the material 2 respectively.

[0026] Since the traction roller 1 reverses to change the winding direction, it is not easy to keep the material 2 flat compared to unidirectional winding, and it is easy to cause wrinkles in the material 2. Therefore, by setting the tensioning roller 3, the tightening degree of the material 2 is adjusted to reduce the possibility of wrinkles in the material 2 when the winding roller rotates forward and reversely.

[0027] Furthermore, the cleaning assembly includes a connecting rod 52 , on which a cleaning member 54 is disposed.

[0028] The device is provided with a horizontally extending mounting frame 44 beside the detection device 4, a slide groove 441 is opened below the mounting frame 44, and a connecting rod 52 is slidably set in the slide groove 441, a tooth structure is provided above the connecting rod 52, and a plurality of springs 53 are connected between the side of the connecting rod 52 and the side wall of the slide groove 441, so that when the components are matched, the cleaning part 54 oscillates back and forth.

[0029] Furthermore, the cleaning member 54 is a brush, and the brush is detachably connected to the connecting rod 52 .

[0030] The cleaning member 54 of the device is configured as a brush, which has a more stable cleaning effect on the material 2 during vibration compared to a rotatable drum, and adopts a detachable connection to facilitate the replacement of the cleaning member 54 at a later time.

[0031] Furthermore, it also includes an adjustment mechanism 43, which includes a second motor, and the output shaft of the second motor is coaxially connected to a screw with positive and negative threads. The detection device 4 is adapted to be threadedly connected to the screw with positive and negative threads, so that when the screw rotates, the two detection parts of the detection device 4 are driven to move closer and farther.

[0032] In order to control the distance between the lighting lamp 41 and the photosensitive component 42 according to usage requirements, the distance between the two is adjusted by the adjustment mechanism 43. The adjustment mechanism 43 can adopt multiple embodiments. The present application provides a preferred embodiment, in which the positive and negative screws are driven to rotate by motor 2, so that the slide seat connected to the two detection components moves close to and away from each other, so that one driving source can drive the position of the two detection components to change at the same time, which is suitable for usage requirements.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
