Description

Technical Field

[0001] This invention relates to the field of adhesive application technology for coating machines, and more specifically to an improved device for applying adhesive to the base film of a coating machine. Background Technology

[0002] A coating machine is a device that uses the rotation of a gluing roller to apply adhesive to fabric. The layered fabric is moved and transported under the rotation of various rollers. The lower part of the gluing roller is immersed in the adhesive tank to adhere to the adhesive. During the rotation process, the adhesive is evenly applied to the fabric. However, the coating machine under the existing technology still has the following shortcomings when applying adhesive.

[0003] Firstly, in existing coating machines, as the coating process progresses, the adhesive in the adhesive tank is gradually consumed, and the adhesive level gradually decreases. When the adhesive roller can no longer contact the adhesive, the operator needs to add adhesive to restore the adhesive level in the tank to the appropriate height. However, the adhesive tank has sufficient depth, and even when the adhesive level drops and cannot contact the adhesive roller, there is still enough adhesive in the tank. Traditional coating machines cannot make this bottom layer of adhesive contact the adhesive roller, thus reducing the utilization efficiency of the adhesive.

[0004] Secondly, in the existing coating machine technology, the adhesive surface of the layered fabric needs to be cleaned before applying the adhesive. If the adhesive surface of the layered fabric is contaminated with some impurities, the adhesive surface will be uneven during the application of adhesive, thus affecting the adhesive effect. In addition, the adhesive machine needs to dry the adhesive on the layered fabric after applying adhesive, but the drying effect of the existing coating machine technology is not ideal.

[0005] Therefore, there is a need to provide an improved device for applying adhesive to the base film of a coating machine to solve the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an improved device for applying adhesive to the base film of a coating machine to solve the problems existing in the background art.

A lower bearing is fixedly mounted on the side plate, and an upper bearing is fixedly mounted on the top of the side plate, directly above the lower bearing. A gluing roller is movably sleeved between the lower bearings, and a limit roller is movably sleeved between the upper bearings. A mounting plate is fixedly mounted on the outer side of the side plate, and a gluing motor is fixedly mounted on the mounting plate. The drive shaft of the gluing motor is fixedly connected to the shaft of the gluing roller. Movable grooves are formed at both the front and rear ends of the inner side of the side plate, and a metal base plate is movably mounted on the movable groove. A compression spring is fixedly connected between the metal base plate and the bottom end of the movable groove.

[0009] Furthermore, a floating groove is formed on the inner wall of the movable groove, and a float plate is movably installed on the floating groove. Electrical contact blocks are fixedly installed on both the upper and lower surfaces of the float plate. A fixing plate is fixedly installed on the top of the movable groove, and a buffer spring is fixedly connected to the bottom of the fixing plate. A contact plate is fixedly installed at the bottom of the buffer spring, and a metal connecting rod is fixedly connected between the contact plates. An air pump is fixedly installed on the front side of the adhesive box, and an air blower is fixedly connected to the output end of the air pump. A one-way valve is fixedly installed on the body of the air blower, and a connecting pipe is fixedly connected to the end of the air blower. Diverter pipes are fixedly connected to both ends of the connecting pipe, and the output ends of the diverter pipes are fixedly connected to the four corners of the bottom of the adhesive box.

[0010] Furthermore, a solenoid valve is fixedly connected to the bottom of the adhesive box, an exhaust pipe is fixedly connected to the bottom of the solenoid valve, and evenly distributed exhaust nozzles are fixedly connected to the bottom of the exhaust pipe. A fabric workpiece is provided between the glue roller and the limiting roller. The control circuit of the air pump is electrically connected to two electrical contact blocks on the upper surface of the front floating plate, and the solenoid valve is electrically connected to two electrical contact blocks on the bottom surface of the front floating plate.

[0011] Furthermore, the drive assembly includes two upright plates located on opposite sides. Each upright plate has two connecting bearings fixedly mounted on it. Each connecting bearing is movably sleeved with a drive cylinder, and each drive cylinder is connected to the fabric workpiece for transmission.

[0012] Furthermore, side plates are fixedly installed on the outer sides of the upright plates, and drive motors are fixedly installed on the side plates. The drive motors are respectively fixedly connected to the shafts of the drive cylinders. A connecting plate is fixedly connected to the front side of each upright plate, and the connecting plate is fixedly connected to the side plate. The cleaning assembly includes a base plate, and each base plate has a mounting groove. Drive rollers are movably sleeved at both ends of the mounting groove. A cleaning motor is fixedly connected to the front shaft of each drive roller. The cleaning motor is fixedly installed on the outer side of the base plate. A cleaning belt is driven between the drive rollers. Evenly distributed cotton brushes are fixedly installed on the outer side of the cleaning belt. The front end of the fabric workpiece is located at the bottom of the cleaning belt, and the cotton brushes at the bottom of the cleaning belt are in contact with the fabric workpiece.

[0013] Furthermore, the drying assembly includes a drying shelf, with uniformly distributed electric heating tubes fixedly installed at the bottom of the drying shelf, a partition fixedly installed on the inner wall of the drying shelf, and uniformly distributed drying fans fixedly installed on the partition. A support is provided at the bottom end of the drying shelf, and the rear transport part of the fabric workpiece is located between the electric heating tubes and the partition. The control circuit of the electric heating tubes is electrically connected to two electric contact blocks on the upper surface of the rear floating plate.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention includes an adhesive application assembly. Adhesive can be injected into the space above the adhesive box and the side plate. After the adhesive is injected, the metal base plate moves down and the float plate floats up. An air pump blows air into the bottom space of the metal base plate through an air blowing pipe and a diversion pipe, thereby supporting the height of the metal base plate. When the liquid level of the adhesive reaches a suitable height, the electrical contact block on the upper surface of the float plate contacts the contact plate. Under the connection of the metal connecting rod, the control circuit of the air pump is short-circuited, thereby turning off the air pump and stopping the blowing. When the liquid level drops after the adhesive is consumed during use, the electrical contact block on the upper surface of the float plate separates from the contact plate, causing the air pump to restart and start blowing air again, thereby ensuring that the liquid level of the adhesive above the metal base plate is always maintained at a suitable height.

[0016] 2. This invention includes a driving component, a cleaning component, and a drying component. When the adhesive above the metal base plate is used up, the floating plate cannot float, causing its bottom electrical contact block to contact the metal base plate. The metal base plate is a conductor, which opens the solenoid valve, allowing air at the bottom of the metal base plate to be sprayed downwards through the exhaust pipe and exhaust nozzle. The adhesive motor drives the adhesive roller to rotate. After the bottom of the adhesive roller is coated with adhesive, the rotation coats the fabric workpiece. During the conveying process, the front end of the fabric workpiece is located at the bottom of the cleaning belt. Driven by the cleaning motor, the cleaning belt drives the cotton brush. The process involves moving the brush to pre-clean the surface of the fabric workpiece, removing impurities and particles that adhere to it. When air from the bottom of the metal base plate is expelled downwards through the exhaust pipe and nozzle, it effectively blows away the impurities. When the adhesive level reaches a suitable height, the electrical contact blocks on the upper surface of the floating plate contact the contact plate, activating the control circuit of the heating element and causing it to heat up, thus drying the adhesive coating on the fabric workpiece. The blowing effect of the drying fan further accelerates airflow in the drying area, resulting in a better drying effect. Attached Figure Description

Lower bearings 103 are fixedly mounted on the side plates 102, and upper bearings 104 are fixedly mounted on the upper side plates 102, directly above the lower bearings 103. A gluing roller 105 is movably sleeved between the lower bearings 103, and a limiting roller 106 is movably sleeved between the upper bearings 104. A mounting plate 107 is fixedly mounted on the outer side of the side plates 102, and a gluing motor 108 is fixedly mounted on the mounting plate 107. The drive shaft of 8 is fixedly connected to the shaft of the gluing roller 105. Movable grooves 109 are provided at both the front and rear ends of the inner side of the side plate 102. A metal base plate 110 is movably mounted on the movable groove 109. A compression spring 111 is fixedly connected between the metal base plate 110 and the bottom end of the movable groove 109. A floating groove 112 is provided on the inner wall of the movable groove 109. A float plate 113 is movably mounted on the floating groove 112. Electrical contact blocks 114 are fixedly mounted on both the upper and lower surfaces of the float plate 113. A fixing plate 115 is fixedly mounted on the top of the movable groove 109. A buffer spring 116 is fixedly connected to the bottom of each of the components 5. A contact plate 117 is fixedly installed at the bottom of the buffer spring 116. A metal connecting rod 118 is fixedly connected between the contact plates 117. An air pump 119 is fixedly installed on the front side of the glue container 101. An air blower 120 is fixedly connected to the output end of the air pump 119. A one-way valve 121 is fixedly installed on the body of the air blower 120. A connecting pipe 122 is fixedly connected to the end of the air blower 120. A diverter pipe 123 is fixedly connected to both ends of the connecting pipe 122. The output end of the diverter pipe 123... The glue roller 105 is fixedly connected to the four corners of the bottom of the glue box 101. The bottom end of the glue box 101 is fixedly connected to a solenoid valve 124. The bottom end of the solenoid valve 124 is fixedly connected to an exhaust pipe 125. The bottom end of the exhaust pipe 125 is fixedly connected to evenly distributed exhaust nozzles 126. A fabric workpiece 127 is provided between the glue roller 105 and the limiting roller 106. The control circuit of the air pump 119 is electrically connected to two electrical contact blocks 114 on the upper surface of the front float plate 113. The solenoid valve 124 is electrically connected to two electrical contact blocks 114 on the bottom surface of the front float plate 113.

[0028] In this embodiment, adhesive can be filled into the space above the adhesive box 101 and the side plate 102. After the adhesive is injected, the metal base plate 110 moves down and the float plate 113 floats up. The air pump 119 blows air into the bottom space of the metal base plate 110 through the air pipe 120 and the diversion pipe 123, thereby supporting the height of the metal base plate 110. When the liquid level of the adhesive reaches a suitable height, the electrical contact block 114 on the upper surface of the float plate 113 contacts the contact plate 117. Under the connecting action of the metal connecting rod 118, the control circuit of the air pump 119 is short-circuited, thereby turning off the air pump 119 and stopping the blowing. When the liquid level drops after the adhesive is consumed during use, the electrical contact block 114 on the upper surface of the float plate 113... Contact block 114 separates from contact plate 117, causing air pump 119 to restart and begin blowing air, thus keeping the adhesive level above metal base plate 110 at a suitable height. When the adhesive above metal base plate 110 is used up, float plate 113 cannot float, causing electrical contact block 114 at its bottom to contact metal base plate 110. Since metal base plate 110 is a conductor, solenoid valve 124 opens, allowing air at the bottom of metal base plate 110 to be sprayed downwards through exhaust pipe 125 and exhaust nozzle 126. Glue application motor 108 drives glue application roller 105 to rotate. After the glue is applied to the bottom of glue application roller 105, it coats the fabric workpiece 127 through rotation.

[0029] Reference Figure 5 The driving assembly 2 includes two upright plates 201, located on opposite sides. Two connecting bearings 202 are fixedly mounted on each upright plate 201, and each connecting bearing 202 is movably sleeved with a driving cylinder 203. The driving cylinders 203 are connected to the fabric workpiece 127. Side plates 204 are fixedly mounted on the outer surfaces of each upright plate 201, and driving motors 205 are fixedly mounted on the side plates 204. The driving motors 205 are fixedly connected to the shafts of the driving cylinders 203. A connecting plate 206 is fixedly connected to the front side of each upright plate 201, and the connecting plate 206 is fixedly connected to the side plate 102. The cleaning component 3 includes a base plate 301, on which mounting grooves 302 are provided. Drive rollers 303 are movably sleeved at both ends of the mounting grooves 302. A cleaning motor 304 is fixedly connected to the front shaft of the drive rollers 303. The cleaning motor 304 is fixedly installed on the outer side of the base plate 301. A cleaning belt 305 is driven and sleeved between the drive rollers 303. Cotton brushes 306 are evenly distributed and fixedly installed on the outer side of the cleaning belt 305. The front end of the fabric workpiece 127 is located at the bottom of the cleaning belt 305. The cotton brushes 306 at the bottom of the cleaning belt 305 are in contact with the fabric workpiece 127.

[0030] In this embodiment, during the conveying process, the front end of the fabric workpiece 127 is located at the bottom of the cleaning belt 305. Under the driving action of the cleaning motor 304, the cleaning belt 305 drives the cotton brush 306 to move, thereby pre-brushing and cleaning the surface of the fabric workpiece 127. After the impurity particles are brushed off by the cotton brush 306 and adhere to the cotton brush 306, when the air at the bottom of the metal base plate 110 is sprayed downward through the exhaust pipe 125 and from the exhaust nozzle 126, a certain blowing and cleaning effect can be achieved on the cotton brush 306.

[0031] Reference Figure 6 The drying assembly 4 includes a drying shelf 401, with uniformly distributed electric heating tubes 402 fixedly installed at the bottom of the drying shelf 401. A partition 403 is fixedly installed on the inner wall of the drying shelf 401, and uniformly distributed drying fans 404 are fixedly installed on the partition 403. A support 405 is provided at the bottom end of the drying shelf 401. The rear transport part of the fabric workpiece 127 is located between the electric heating tubes 402 and the partition 403. The control circuit of the electric heating tubes 402 is electrically connected to two electric contact blocks 114 on the upper surface of the rear floating plate 113.

[0032] In this embodiment, when the liquid level of the adhesive reaches a suitable height, the electrical contact block 114 on the upper surface of the float 113 comes into contact with the contact plate 117, which activates the control circuit of the heating element 402 and causes the heating element 402 to heat up, thereby drying the adhesive layer of the fabric workpiece 127. The blowing effect of the drying fan 404 can accelerate the air circulation in the drying area, thereby improving the drying effect.

[0033] The working principle of this invention: Adhesive can be injected into the space above the adhesive box 101 and the side plate 102. After the adhesive is injected, the metal base plate 110 moves downward and the float plate 113 floats. The air pump 119 blows air into the bottom space of the metal base plate 110 through the air pipe 120 and the diversion pipe 123, thereby supporting the height of the metal base plate 110. When the liquid level of the adhesive reaches a suitable height, the electrical contact block 114 on the upper surface of the float plate 113 contacts the contact plate 117. Under the connecting action of the metal connecting rod 118, the control circuit of the air pump 119 is short-circuited, thereby... The air pump 119 is turned off and stops blowing air. When the adhesive is consumed during use and the liquid level drops, the electrical contact block 114 on the upper surface of the float 113 separates from the contact plate 117, causing the air pump 119 to restart and begin blowing air. This ensures that the adhesive level above the metal base plate 110 is always maintained at a suitable height. When the adhesive above the metal base plate 110 is depleted, the float 113 cannot float, causing the electrical contact block 114 at its bottom to contact the metal base plate 110. Since the metal base plate 110 is a conductor, this causes the solenoid valve 124 to open, thereby allowing the metal base plate to... Air at the bottom of plate 110 is ejected downwards through exhaust pipe 125 and exhaust nozzle 126. Glue-applying motor 108 drives glue-applying roller 105 to rotate. After the bottom of glue-applying roller 105 is coated with adhesive, it coats the fabric workpiece 127 through rotation. During transport, the front end of fabric workpiece 127 is located at the bottom of cleaning belt 305. Driven by cleaning motor 304, cleaning belt 305 drives cotton brush 306 to move, thus pre-cleaning the surface of fabric workpiece 127. Impurities are removed by cotton brush 306 and adhere to it. After 06, when the air at the bottom of the metal base plate 110 is sprayed downward through the exhaust pipe 125 and from the exhaust nozzle 126, it can achieve a certain blowing and cleaning effect on the cotton brush 306. When the liquid level of the adhesive reaches a suitable height, the electric contact block 114 on the upper surface of the float plate 113 comes into contact with the contact plate 117, which activates the control circuit of the heating tube 402 and turns on the heating tube 402 to heat up, thereby drying the adhesive layer of the fabric workpiece 127. The blowing effect of the drying fan 404 can accelerate the air circulation in the drying part, thereby making the drying effect better.
