Description

Technical Field

[0001] This invention relates to the field of profile processing equipment technology, specifically to an automatic amplitude-adjusting feeding and coating machine assembly. Background Technology

[0002] In the field of modern materials processing and decoration, coating machines are widely used to coat the surfaces of profiles, sheets, and other workpieces with film materials (such as PVC, decorative paper, etc.). The gluing and workpiece conveying systems are the core components that determine the coating quality and efficiency.

[0003] Traditional coating equipment typically suffers from two major drawbacks: First, on the workpiece processing side, the widths of the workpieces to be coated vary or have tolerances. Traditional equipment lacks effective online amplitude adjustment and centering mechanisms, which can cause workpieces to deviate or become inaccurately positioned when entering the coating area, directly affecting the uniformity of subsequent coating. Second, on the gluing mechanism side, the width of the glue outlet is usually fixed or requires manual mechanical adjustment. When the width of the membrane material changes, a fixed-width glue outlet can cause glue to be applied to areas outside the membrane material, resulting in glue waste and contamination of the equipment and working environment. More importantly, the membrane material itself may experience slight fluctuations during transport, which traditional mechanisms cannot respond to in real time. This can lead to uneven gluing at some membrane edges, resulting in poor coating, bubbling, and other quality problems, severely impacting the yield.

[0004] Therefore, there is an urgent need in this field for a comprehensive solution that can address both workpiece width adjustment and film coating issues, namely, an intelligent coating device that can automatically adapt to changes in workpiece width and simultaneously achieve precise matching between the adhesive width and the real-time width of the film, thereby enabling efficient, clean, and high-quality stable production.

The baking oven 300, the auxiliary liquid coating device 400, and the dust removal device 500 are arranged sequentially between the gluing mechanism 100 and the second workpiece amplitude adjustment assembly 600. The baking oven 300 is located close to the gluing mechanism 100. The gluing mechanism 100 includes a gluing base 110, a second support frame 140, and a third support frame 150. The second support frame 140 is slidably connected to the gluing base 110, and the third support frame 150 is fixedly connected to the gluing base 110. An adjusting rod group 153 is fixedly connected to the side of the third support frame 150 away from the second support frame 140. An amplitude adjustment transmission assembly is provided at the bottom of the assembly frame. The amplitude adjustment transmission assembly is used to synchronize the amplitude adjustment of the first workpiece amplitude adjustment assembly 200 and the second workpiece amplitude adjustment assembly 600.

[0034] The end of the adjusting rod assembly 153 away from the third support frame 150 is fixedly connected to the first support frame 120. The first support frame 120 is provided with a glue dispensing component and an adjusting component. The second support frame 140 is rotatably provided with a feeding component. The third support frame 150 is rotatably connected with a guiding component. The glue application base 110 is fixedly connected with a flattening roller 113. The glue application base 110 is rotatably connected with several feeding rollers 111. The glue application base 110 is fixedly connected with a covering platform 112 and a flattening roller 113.

[0035] The adhesive base 110 is equipped with a composite pressure roller at the coating platform 112. The composite pressure roller is existing technology.

[0036] The second support frame 140 is fixedly and slidably connected to the adjusting slide rail 148, which is fixedly connected to the adhesive base 110. The third support frame 150 is fixedly connected to the second infrared sensor 149, which is used to measure the shape and position of the film material on the first guide roller 147. Based on the measurement results, the adjusting slide rail 148 drives the film roll 142 to move, thereby ensuring the neatness of the film material roll.

[0037] The glue dispensing assembly includes a lower opening 126 and an upper opening 127 of the glue knife, which overlap each other. A flow-limiting sliding groove 128 is formed on the overlapping surface of the lower opening 126 and the upper opening 127. Several glue injection channels 129 are fixedly connected to the side of the upper opening 127 away from the flow-limiting sliding groove 128. A glue injection system is connected to the glue injection channels 129. A glue outlet is provided on the side of the lower opening 126 and the upper opening 127 near the third guide roller 152. The glue outlet is connected to the flow-limiting sliding groove 128.

[0038] The adjustment assembly includes a first sliding push rod 121 and a second sliding push rod 130. Both the first sliding push rod 121 and the second sliding push rod 130 are slidably connected to the first support frame 120. One end of the first sliding push rod 121 is fixedly connected to a first connecting rod 122, and the other end of the first sliding push rod 121 is fixedly connected to a flow limiting rod 125. One end of the second sliding push rod 130 is fixedly connected to an adjusting slider 124, and the other end of the second sliding push rod 130 is fixedly connected to a first infrared sensor 131. The adjusting slider 124 is detachably connected to an adjusting slide rod 123, and the adjusting slide rod 123 is fixedly connected to the first connecting rod 122. The flow limiting rod 125 is slidably connected to the flow limiting sliding groove 128.

[0039] It is worth noting that the first infrared sensor 131 is electrically connected to the first sliding push rod 121. The first sliding push rod 121 slides relative to the first support frame 120 according to the film width detected by the first infrared sensor 131, thereby driving the flow limiting rod 125 to slide relative to the flow limiting sliding groove 128. Thus, the effective glue dispensing width of the flow limiting sliding groove 128 is limited by the flow limiting rod 125. A tension sensor is also provided on the second guide roller 151. The tension sensor is used to measure the real-time tension of the film material. The first infrared sensor 131, the second infrared sensor 149 and the tension sensor are all electrically connected to the control chip.

[0040] The feeding assembly includes a drive shaft 141, an air expansion shaft 144, and a magnetic powder brake 146. A film roll 142 is wound around the outer surface of the drive shaft 141. The drive shaft 141 is rotatably connected to a second support frame 140. One end of the drive shaft 141 is mounted on the second support frame 140, and the other end of the drive shaft 141 is fixedly connected to a hexagonal shaft 143. The air expansion shaft 144 is fixedly connected to the side of the second support frame 140 near the hexagonal shaft 143. An active push rod 145 is rotatably connected to the outer surface of the air expansion shaft 144. The air expansion shaft 144 is fixed to the output shaft of the magnetic powder brake 146, and the base of the magnetic powder brake 146 is fixedly connected to the second support frame 140.

[0041] The guiding assembly includes a first guide roller 147, a second guide roller 151, and two third guide rollers 152. The first guide roller 147 is rotatably connected to the second support frame 140, and the second guide roller 151 and the third guide rollers 152 are both rotatably connected to the third support frame 150.

[0042] The first workpiece amplitude adjustment assembly 200 includes a fourth support frame 201 and a first workpiece amplitude adjustment plate 204. A guide roller group 202 is rotatably connected to the fourth support frame 201. A sliding limit rod 203 and an amplitude adjustment plate support frame 205 are fixedly connected to the fourth support frame 201. The first workpiece amplitude adjustment plate 204 is slidably connected to the sliding limit rod 203 and the amplitude adjustment plate support frame 205.

[0043] One end of the amplitude modulation transmission assembly is rotatably connected to the amplitude modulation plate support frame 205, and the other end of the amplitude modulation transmission assembly is rotatably connected to the second workpiece amplitude modulation assembly 600. It includes several transmission ends 701 and several transmission rods 702. The two ends of the transmission rods 702 are respectively fixedly connected to the transmission ends 701, and one of the transmission ends 701 is rotatably connected to the amplitude modulation plate support frame 205.

[0044] The second workpiece amplitude adjustment assembly 600 includes several feed conveyor rollers 601 and a second workpiece amplitude adjustment plate 602. The feed conveyor rollers 601 are rotatably connected to the main assembly frame. The second workpiece amplitude adjustment plate 602 is provided with several sliding limiting grooves 603, which are adapted to the second workpiece amplitude adjustment plate 602. The second workpiece amplitude adjustment plate 602 is slidably connected to the feed conveyor rollers 601.

[0045] When this solution is used for coating, firstly, the workpiece to be coated is placed on the feed conveyor roller 601 of the second workpiece amplitude adjustment component 600, the film roll 142 is installed on the drive shaft 141 and fixed, and the end of the film is passed through the first guide roller 147, the second guide roller 151, the third guide roller 152 and other guide components in sequence to form the correct conveying path.

[0046] Then, adhesive is injected into the adhesive storage tank 129 formed by the upper and lower adhesive cover plates. According to the preset width of the workpiece, the reference parameters of the membrane width sensor 131 are set by the control system. The first and second sliding push rods will move to their initial positions.

[0047] During the transfer process, the workpiece is initially guided and positioned by the second workpiece amplitude adjustment plate 602. Through the linkage of the transmission rod 702 and the transmission end 701, the first workpiece amplitude adjustment plate 204 of the first workpiece amplitude adjustment assembly 200 is adjusted synchronously to ensure that the workpiece has a consistent width and is centered before entering the covering area.

[0048] Next, the workpiece is pre-treated: the workpiece passes through the dust removal device 500 (for cleaning the workpiece), the auxiliary liquid coating device 400 (for coating the workpiece with auxiliary liquid or treatment agent), and the baking oven 300 (for drying and preheating the workpiece) for surface treatment, and then enters the gluing mechanism 100. The gluing mechanism 100 applies glue to the film material and laminates it onto the workpiece, and flattens the film material, removes air bubbles, and ensures that the coating is flat and firm.

[0049] Finally, after the coating is completed, the drive motor stops, all system components reset, and the operator can replace the film roll and clean and maintain the gluing mechanism, scraper, and other components to prepare for the next operation.

[0050] When this solution is used for automatic gluing of the coating machine, the equipment is first initialized and parameters are preset. The operator installs the film roll 142 onto the drive shaft 141 and fixes it to the air shaft 144 via the hexagonal shaft 143 to ensure stable rotation.

[0051] Subsequently, the membrane end is sequentially routed around the first guide roller 147, the second guide roller 151, and the two third guide rollers 152 to form the correct conveying path. In the glue dispensing assembly, sufficient glue is injected into the glue injection channel 129 formed by the overlapping of the lower opening 126 and the upper opening 127 of the glue knife, and the glue is then applied to the surface of the membrane.

[0052] Based on the basic width of the workpiece to be covered, the reference parameters of the first infrared sensor 131 are preset by the control chip. At this time, the adjustment component is in the initial standby state: the second sliding push rod 130 can drive the adjustment slider 124 and the first infrared sensor 131 to move to the approximate position according to the preset value. The first sliding push rod 121 then drives the first connecting rod 122 and the flow limiting rod 125 fixed thereon to maintain an initial alignment relationship with the flow limiting sliding groove 128, preparing for subsequent precise adjustment.

[0053] Then, the control chip drives the device to apply adhesive and make dynamic adjustments. The magnetic powder brake 146 is opened, and the drive shaft 141 drives the film roll 142 to rotate at a constant speed. The film is then pulled out and conveyed forward along the path laid by the guide assembly.

[0054] Meanwhile, the adhesive in the dispensing channel 129 flows into the flow-limiting sliding groove 128 under the action of gravity and pressure. The key to this stage lies in the closed-loop feedback regulation of the system: the first infrared sensor 131 monitors the actual width of the membrane material in real time and feeds the signal back to the control chip.

[0055] The first sliding push rod 121 drives the flow limiting rod 125 to slide precisely laterally within the flow limiting sliding groove 128 via the first connecting rod 122, thereby changing the effective glue outlet width of the flow limiting sliding groove 128 so that the glue outlet range always matches the real-time film width, effectively avoiding glue waste and pollution.

[0056] After precise adhesive control, the film material is conveyed to the coating platform 112, where the flattening roller 113 flattens the film material and, with the assistance of the feeding roller 111, it is tightly bonded to the surface of the workpiece by the composite pressure roller to eliminate air bubbles and complete high-quality coating.

[0057] Finally, when the coating operation is completed, the magnetic powder brake 146 is closed, the film material conveying stops, the glue dispensing system is closed, the glue injection channel 129 stops supplying glue, the first sliding push rod 121 and the second sliding push rod 130 are reset, the flow limiting rod 125 is removed from the working area, and the first infrared sensor 131 also returns to its initial position.

[0058] Operators can operate the active push rod 145 to release the lock between the air expansion shaft 144 and the hexagonal rotating shaft 143, and conveniently replace the depleted membrane roll 142. They can also clean and maintain the components that come into contact with the adhesive and membrane, such as the lower opening 126 of the glue knife, the upper opening 127 of the glue knife, the flow limiting sliding groove 128, and the flattening roller 113, to ensure that the mechanism can still maintain its best working condition when used next.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
