A resin product sticker device

Abstract

This invention discloses a resin product labeling device, relating to the field of product labeling technology. It includes two symmetrically arranged support frames, with a push plate fixedly installed on the upper surface of each support frame. A connecting plate is fixedly installed on the top of the push plate, and an external frame is installed between the connecting plates on both sides. This invention utilizes a clever combination of a cleaning mechanism and a labeling mechanism, allowing the labeling mechanism to clean the resin board before labeling, effectively preventing dust and impurities adhering to the resin board from affecting the labeling effect. When the liquid reservoir is compressed by the piston rod, dust on the resin board surface can be adsorbed through the air pipe and air cylinder, achieving a secondary cleaning effect. When the piston rod moves down to its reset position, it generates a suction force on the hydraulic oil in the cavity, and the air cylinder can blow the label onto the resin surface, accelerating the bonding speed between the hot melt adhesive surface of the label and the resin board.

Description

Technical Field

[0001] This invention relates to the field of product sticker technology, and more specifically to a resin product sticker application device. Background Technology

[0002] New ecological resin board, also known as light-transmitting resin board, is made of an amorphous copolymer through a high-temperature lamination process. It has excellent light transmission, flame retardant properties, sound insulation, impact resistance, anti-yellowing, anti-deformation, anti-chemical corrosion, and is lightweight. It also has UV function, high surface hardness, and can be shaped into any shape.

[0003] Resin boards (such as acrylic, PVC, etc.) are prone to scratches. Stickers can protect them and extend their service life. Resin boards may develop scratches and bubbles during processing or use. Stickers can repair the appearance at low cost.

[0004] In the existing technology, when applying stickers to resin boards, both sides of the resin board usually need to be stickered. At the same time, in order to ensure the adhesion of the sticker, the surface of the resin board is cleaned before the sticker is applied. The sticker application and cleaning cannot be carried out in conjunction, which greatly reduces the sticker application efficiency of resin boards. Summary of the Invention

[0005] The purpose of this invention is to provide a resin product sticker application device to solve the following technical problems:

[0006] Existing sticker-applying equipment struggles to efficiently apply stickers to both sides of resin boards.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A resin product labeling device includes two symmetrically arranged support frames. A push plate is fixedly installed on the upper surface of the support frame, and a connecting plate is fixedly installed on the top of the push plate. An outer frame is installed between the connecting plates on both sides. A liquid storage cylinder one and a liquid storage cylinder two are respectively installed on both sides of the outer frame. A piston rod is slidably installed in the middle of the liquid storage cylinder one, and a contact frame is fixedly installed at one end of the piston rod. The piston rod and the inner cavity of the liquid storage cylinder one form a cavity for storing hydraulic oil. A labeling mechanism is detachably installed in the middle of the outer frame. Cleaning mechanisms are provided on both sides of the outer frame. Multiple equally spaced conveyor frames are rotatably installed on the inner side of the support frames on both sides through a conveying mechanism. A flipping frame is provided in the middle of the conveyor frame. The flipping frame is connected to the conveyor frame through a flipping component. An opening and closing component is also provided on the flipping frame.

[0009] The cleaning mechanism includes a vertical slot on the external frame, a lifting component that is slidably installed in the vertical slot, a spring that is installed between the upper end face of the lifting component and the vertical slot, a shaft that is rotatably installed on the lifting component, a gear located in the middle of the lifting component that is fixedly installed in the middle of the shaft, and a toothed plate that is fixed to the piston rod on the side of the gear away from the external frame.

[0010] Both ends of the shaft are fixedly mounted with rotating frames, and a cleaning roller for cleaning the resin board before applying the sticker is installed between the rotating frames on both sides.

[0011] Preferably, the upper side of the liquid storage cylinder one is provided with an inlet pipe that communicates with the inner cavity of the liquid storage cylinder two, and the side of the liquid storage cylinder one away from the inlet pipe is also provided with an outlet pipe that communicates with the liquid storage cylinder two. One-way valves are provided in the outlet pipe and the inlet pipe.

[0012] Preferably, air cylinders are fixedly installed at the four corners of the lower end face of the external frame, and air outlets are provided in the middle of the lower end face of the air cylinders. Multiple air cylinders are interconnected, and an air transmission pipe is installed between two air cylinders on one side. The end of the air transmission pipe away from the two air cylinders is connected to the lower part of the liquid storage cylinder.

[0013] Preferably, Y-shaped plates are slidably installed at the four corners of the flip frame, and through slots are provided above the Y-shaped plates on the flip frame. Vertical rods fixedly connected to the Y-shaped plates are slidably installed in the through slots. Cylinders are fixedly installed on both sides of the flip frame, and movable frames are fixedly installed at the telescopic ends of the cylinders. The vertical rods on both sides of the movable frames are respectively fitted onto the vertical rods on both sides.

[0014] Preferably, the flipping assembly includes inner side plates installed on both sides of the inner cavity of the conveyor frame. A placement component fixedly connected to the flipping frame is placed on the inner side plate. A guide plate is rotatably installed between the placement component and the inner side plate. A pressure plate is rotatably installed on the placement component. A vertical plate fixed to the conveyor frame is rotatably installed in the middle of the pressure plate. A connecting shaft is installed between the two pressure plates. A kit is sleeved on the outside of the connecting shaft. A telescopic rod fixedly connected to the conveyor frame is fixedly installed at the lower part of the kit.

[0015] Preferably, the opening and closing assembly includes two sets of opening and closing plates that are rotatably arranged on the left and right sides of the flip frame. The two opening and closing plates in each set are always arranged at right angles. The front and rear of the opening and closing plates are provided with side grooves, and the side grooves are slidably installed with moving blocks. The flip frame is equipped with center wheels that are rotatably installed on both sides by a motor.

[0016] Preferably, the center wheel has racks that slide with the flipping frame on its upper and lower sides, and the upper and lower racks are respectively engaged with side wheels that rotate with the flipping frame. A flipping plate is coaxially mounted on the front side of the side wheel, and the flipping plates on both sides are symmetrically arranged. The flipping plates are respectively connected to the upper and lower moving blocks.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention utilizes the ingenious cooperation between the cleaning mechanism and the sticker mechanism, so that the sticker mechanism cleans the resin board before applying the sticker, thereby effectively avoiding the situation where dust and impurities adhering to the outside of the resin board affect the sticker application effect.

[0019] 2. In this invention, after the resin board is coated on one side, the conveying mechanism drives the conveying frame to continue moving. Since the conveying frame is set up in an open manner, and after the conveying mechanism rotates one revolution, the flipping frame is once again below the coating mechanism. At this time, the flipping component opens and drives the flipping frame to flip inside the conveying frame. The opening and closing component works in conjunction with the flipping component. At this time, the side of the resin board that has been coated faces the ground. The opening and closing component supports the side of the resin board that has been coated, and the side of the resin board that has not been coated faces the coating mechanism. Repeating the downward movement of the coating mechanism as described above can complete the coating of both sides of the resin board.

[0020] 3. When the liquid storage cylinder of the present invention is compressed by the external force of the piston rod, the dust on the surface of the resin board can be adsorbed through the air transmission pipe and the air cylinder, achieving the effect of secondary cleaning. When the sticker mechanism moves up and the piston rod moves down to reset, it generates a suction force on the hydraulic oil in the cavity. The air cylinder can blow the sticker on the resin surface, which on the one hand accelerates the bonding speed between the hot melt adhesive surface of the sticker and the resin board, and on the other hand promotes the adhesion between the sticker and the resin board.

[0021] 4. In this invention, when the piston rod drives the contact frame to move upward, the gear is driven to rotate through the toothed plate, which in turn drives the cleaning roller to roll and stick to the surface of the resin board and then open it, thereby giving space for the sticker mechanism to apply the sticker. This effectively rolls and sticks to the surface of the resin board to ensure the removal of dust and impurities from its surface. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 and Figure 8 As shown, the present invention is a resin product labeling device, including two symmetrically arranged support frames 1. A push plate 10 is fixedly installed on the upper surface of the support frame 1, and a connecting plate 11 is fixedly installed on the top of the push plate 10. An outer frame 12 is installed between the connecting plates 11 on both sides. A liquid storage cylinder 14 and a liquid storage cylinder 15 are respectively installed on both sides of the outer frame 12. A piston rod 141 is slidably installed in the middle of the liquid storage cylinder 14. A contact frame 142 is fixedly installed at one end of the piston rod 141. The piston rod 141 and the inner cavity of the liquid storage cylinder 14 enclose a cavity for storing hydraulic oil. A labeling mechanism 13 is detachably installed in the middle of the outer frame 12. Cleaning mechanisms are provided on both sides of the outer frame 12. Multiple equally spaced conveyor frames 2 are rotatably installed on the inner side of the support frame 1 on both sides through a conveying mechanism. A flip frame 23 is provided in the middle of the conveyor frame 2. The flip frame 23 is connected to the conveyor frame 2 through a flipping component. An opening and closing component is also provided on the flip frame 23.

[0033] The cleaning mechanism includes a vertical slot on the outer frame 12, a lifting component 16 is slidably installed in the vertical slot, a spring is installed between the upper end face of the lifting component 16 and the vertical slot, a shaft 161 is rotatably installed on the lifting component 16, a gear 162 located in the middle of the shaft 161 is fixedly installed in the middle of the lifting component 16, and a toothed plate 143 fixed to the piston rod 141 is meshed on the side of the gear 162 away from the outer frame 12.

[0034] Both ends of the shaft 161 are fixedly mounted with rotating frames 163, and a cleaning roller 164 for cleaning the resin board before applying the sticker is installed between the rotating frames 163 on both sides.

[0035] Multiple conveyor frames 2 are sequentially conveyed to the area below the sticker application mechanism 13 by the opening of the conveying mechanism. At the same time, the push plate 10 opens and retracts, driving the outer frame 12 to descend via the connecting plate 11. Finally, the sticker application mechanism 13 applies stickers to one side of the resin board on the conveyor frame 2. When the outer frame 12 is descending, the piston rod 141 first contacts the opening and closing component that holds the resin board. At this time, the piston rod 141 moves upward in the first liquid storage tank 14 after receiving a reaction force. When the piston rod 141 moves upward, it compresses the hydraulic oil in the chamber. After being compressed, the hydraulic oil is transferred to the second liquid storage tank 15 for temporary storage. When the piston rod 141 moves upward, it simultaneously drives the cleaning mechanism to clean the surface of the resin board that is about to be stickered by rolling and sticking dust. Compared with the existing sticker application equipment, this invention utilizes the clever cooperation between the cleaning mechanism and the sticker application mechanism 13 to clean the resin board before applying the sticker, thereby effectively avoiding the situation where dust and impurities adhering to the outside of the resin board affect the sticker application effect.

[0036] After the resin board is coated on one side, the conveying mechanism drives the conveying frame 2 to continue moving. Since the conveying frame 2 is open at the top and bottom, and after the conveying mechanism rotates one revolution, the flipping frame 23 is once again below the coating mechanism 13. At this time, the flipping component opens and drives the flipping frame 23 to flip inside the conveying frame 2. The opening and closing component works in conjunction with the flipping component. At this time, the side of the resin board that has been coated faces the ground. The opening and closing component supports the side of the resin board that has been coated, and the side of the resin board that has not been coated faces the coating mechanism 13. Repeating the downward movement of the coating mechanism 13 can complete the coating of both sides of the resin board. Compared with the existing coating device, the present invention can coat both sides of the resin board, and there is no need to repeatedly flip and fix the resin board during the coating process.

[0037] It should be noted that the conveying mechanism is a pulley belt, and the sticker application process of the sticker application mechanism 13 is existing technology to complete common sticker application operations, so the sticker application process will not be described in detail.

[0038] In this embodiment, an inlet pipe 17 communicating with the inner cavity of a second liquid storage cylinder 15 is provided on one side of the upper part of the first liquid storage cylinder 14. An outlet pipe 18 communicating with the second liquid storage cylinder 15 is also provided on the side of the first liquid storage cylinder 14 away from the inlet pipe 17. One-way valves are provided in the outlet pipe 18 and the inlet pipe 17. When the first liquid storage cylinder 14 is compressed by the external force of the piston rod 141, the hydraulic oil in the inner cavity of the first liquid storage cylinder 14 is discharged to the second liquid storage cylinder 15 through the outlet pipe 18. The space in the inner cavity of the first liquid storage cylinder 14 on the side of the piston rod 141 away from the hydraulic oil generates a suction force. At this time, the dust on the surface of the resin board can also be adsorbed through the air transmission pipe 191 and the air cylinder 19, realizing the effect of secondary cleaning. When the sticker mechanism 13 finishes cleaning the resin board, the sticker is applied. Then, the push plate 10 opens and pushes upward to move the sticker mechanism 13 away from the resin board surface. At this time, the piston rod 141 loses pressure. Since the piston rod 141 is equipped with a spring, the piston rod 141 quickly resets. When the piston rod 141 moves down to reset, it generates a suction force on the hydraulic oil in the cavity. At this time, the inlet pipe 17 transfers the hydraulic oil in the reservoir 15 back to the reservoir 14. At the same time, the space in the reservoir 14 away from the hydraulic oil decreases as the piston rod 141 moves down. At this time, the gas inside can also blow the sticker on the resin surface through the air transmission pipe 191 and the air cylinder 19. On the one hand, it accelerates the bonding speed between the hot melt adhesive surface of the sticker and the resin board, and on the other hand, it promotes the adhesion between the sticker and the resin board.

[0039] In this embodiment, when the piston rod 141 drives the contact frame 142 to move upward, it also drives the toothed plate 143 to move upward simultaneously. When the toothed plate 143 moves upward, it drives the gear 162 to rotate. When the gear 162 rotates, it drives the rotating frame 163 to rotate simultaneously through the shaft 161. When the rotating frame 163 rotates, it drives the cleaning roller 164 to rotate, thereby opening after rolling and sticking to the surface of the resin board, thus making room for the sticker application mechanism 13 to apply the sticker. Furthermore, the lifting member 16 moves within the vertical groove, which can effectively prevent the resin board from restricting the cleaning roller 164 when the rotating frame 163 drives the cleaning roller 164 to rotate. This ensures that when the cleaning roller 164 rotates with the rotating frame 163, it effectively rolls and sticks to the surface of the resin board to ensure the removal of dust and impurities from its surface.

[0040] Air cylinders 19 are fixedly installed at the four corners of the lower end face of the external frame 12. Air cylinders 19 have air outlets in the middle of the lower end face. Multiple air cylinders 19 are interconnected. A transmission pipe 191 is installed between two air cylinders 19 on one side. The end of the transmission pipe 191 away from the two air cylinders 19 is connected to the lower part of the liquid storage tank 14.

[0041] Example 2: Based on Example 1, please refer to... Figure 4 , Figure 5 as well as Figure 6Y-shaped plates 24 are slidably installed at the four corners of the flip frame 23. A through groove is provided on the top of the Y-shaped plate 24 in the flip frame 23, and a vertical rod 243 fixedly connected to the Y-shaped plate 24 is slidably installed in the through groove. Cylinders 241 are fixedly installed on both sides of the flip frame 23. A movable frame 242 is fixedly installed at the telescopic end of the cylinder 241. The vertical rods 243 are respectively sleeved on both sides of the movable frame 242. When the cylinders 241 are opened and retracted, the movable frames 242 on both sides move closer to each other. When the two movable frames 242 move closer to each other, the Y-shaped plate 24 moves through the vertical rod 243 until it clamps and restricts the side of the resin board at the opposite corner. By restricting and fixing the four corners of the resin board, it can prevent the resin board from sliding when applying the sticker, and it can also prevent the resin board from falling when the flip mechanism is opened and the flip frame 23 is flipped.

[0042] In this embodiment, please refer to Figures 4-5 The flipping assembly includes inner side plates 21 installed on both sides of the inner cavity of the conveyor frame 2. A placement piece 22 fixedly connected to the flipping frame 23 is placed on the inner side plates 21. A guide plate 220 is rotatably installed between the placement piece 22 and the inner side plates 21. A pressure plate 27 is rotatably installed on the placement piece 22. A vertical plate 271 fixed to the conveyor frame 2 is rotatably installed in the middle of the pressure plate 27. A connecting shaft 272 is installed between the two pressure plates 27. A kit 273 is sleeved on the outside of the connecting shaft 272. A telescopic rod 274 fixedly connected to the conveyor frame 2 is fixedly installed at the lower part of the kit 273. When the telescopic rod 274 opens and retracts, it causes the pressure plate 27 to press down and flip on the vertical plate 271. When the pressure plate 27 lifts the placement piece 22, it disengages from the inner side plates 21. Then the guide plate 220 swings, causing the flipping frame 23 to flip. Then the telescopic rod 274 opens and pushes up to reset. At this time, the placement piece 22 is placed back on the inner side plates 21.

[0043] The opening and closing assembly includes two sets of opening and closing plates 25 that are rotatably arranged on the left and right sides of the flip frame 23. The two opening and closing plates 25 in each set are always arranged at right angles. The front and rear of the opening and closing plates 25 are provided with side grooves 251, and the side grooves 251 are slidably installed with moving blocks 252. The flip frame 23 has central wheels 26 installed on both sides by a motor.

[0044] The center wheel 26 has racks 261 that slide with the flip frame 23 on its upper and lower sides. The upper and lower racks 261 are respectively engaged with side wheels 262 that rotate with the flip frame 23. A flip plate 263 is coaxially mounted on the front side of the side wheel 262. The flip plates 263 on both sides are symmetrically arranged. The flip plates 263 are respectively connected to the upper and lower moving blocks 252.

[0045] It can be explained that when the motor is turned on, it drives the central wheel 26 to rotate. At this time, the rack 261 drives the side wheels 262 on both sides to rotate. When the side wheels 262 rotate, they simultaneously drive the flipping plate 263 to rotate. When the flipping plate 263 rotates, it drives the state of the upper and lower opening and closing plates 25 to change alternately. This adapts to the flipping frame 23 after it is flipped. By changing the state of the upper and lower opening and closing plates 25, the resin board is always supported on one side. Compared with the existing sticker device, this invention can use the alternation of the state of the two opening and closing plates 25 to deal with the support of the resin board after it is flipped, avoiding the situation where the resin board is only clamped on the outside when applying stickers, which may cause the resin board to fall off.
