A double-sided adhesive applicator for paper boxes

Abstract

This application relates to the field of paper box processing technology, and in particular to a paper box double-sided adhesive applicator. To solve the problems of difficulty in positioning the double-sided adhesive using only a pressure roller, and difficulty in quickly cutting the double-sided adhesive after the paper box is pasted, the device includes a worktable with a conveying mechanism inside. This application utilizes a servo motor, a threaded rod, and a perforated slider to adjust the position of the adjustment mechanism. A double-sided adhesive storage tray stores the double-sided adhesive. A spring and a U-shaped plate work together to push the U-shaped plate upwards, causing the U-shaped plate to drive a rotating roller upwards. The rotating roller, in conjunction with a curved plate, clamps the double-sided adhesive, preventing it from swinging. A first connecting seat, a second connecting seat, and an arc-shaped plate work together to allow the spring to move upwards, which in turn applies a downward pulling force to the sliding rod. This causes the L-shaped plate and pressure roller to move downwards when separated from the paper box, driving a cutting blade to cut the double-sided adhesive, facilitating subsequent double-sided adhesive application and reducing adhesive waste.

Description

Technical Field

[0001] This application relates to the field of paper box processing technology, and in particular to a paper box double-sided adhesive applicator. Background Technology

[0002] Paper box processing refers to the process of making various types of paper box packaging products by processing cardboard or paper through a series of processes. Paper box processing involves not only the selection and cutting of materials, but also forming, printing, gluing and other links. It is widely used in commodity packaging, transportation, display and other fields. In the process of processing paper boxes, double-sided tape is required to stick the paper boxes together.

[0003] The existing double-sided adhesive applicator for cardboard boxes includes a frame and a belt conveyor mounted on the frame. Two sets of fixed seats are fixedly connected to both sides of the frame. Adjustable seats are rotatably mounted on the inner side of each of the two sets of fixed seats. An adjusting rod passes through the adjusting seats on the two sets of fixed seats, and moves within the arc-shaped groove for adjustment. The angle is locked by a locking nut, allowing for rotatable adjustment of the adhesive application angle between the applicator and the cardboard box conveyed on the belt conveyor. Rotating the adjusting screw by adjusting the handwheel moves the sliding seat and mounting bracket, allowing for free adjustment of the position of the applicator itself and the adhesive application position on the cardboard box. The double-sided adhesive tape is then applied to the surface of the cardboard box by the applicator rollers and pressure rollers.

[0004] However, in actual use, when the cardboard box is not conveyed to the bottom of the double-sided tape, it is difficult to position the double-sided tape using only the clamping rollers, and it is also difficult to quickly cut the double-sided tape after the cardboard box is pasted. Therefore, this needs to be improved. Utility Model Content

[0005] To achieve the desired positioning and rapid cutting of double-sided tape, this application provides a double-sided tape applicator for paper boxes.

[0006] The paper box double-sided adhesive applicator provided in this application adopts the following technical solution:

[0007] A double-sided adhesive applicator for paper boxes includes a workbench with a conveying mechanism inside. An adjustment mechanism is fixedly installed on the upper surface of the workbench. An adhesive applicator is located above the workbench and is mounted on the adjustment mechanism. The adhesive applicator is driven by the adjustment mechanism. A cutting mechanism for cutting double-sided adhesive is located above the adhesive applicator. The control structure of the cutting mechanism is hinged to the adhesive applicator.

[0008] By adopting the above technical solution, the conveying mechanism conveys the cardboard box, moves the cardboard box to below the adhesive applicator, and uses the adjusting mechanism to drive the adhesive applicator to move, so that the adhesive applicator is adjusted according to the position of the cardboard box. After the adhesive applicator completes the adhesive application, the cutting mechanism cuts the double-sided tape.

[0009] Optionally, the adhesive applicator includes a double-sided adhesive storage tray. A connecting plate is fixedly installed on the right side of the double-sided adhesive storage tray. A curved plate is fixedly installed on the bottom surface of the connecting plate. A spring is fixedly installed on the upper surface of the curved plate. A U-shaped plate is fixedly installed on the top of the spring. A rotating wheel is rotatably installed on the inner wall of the U-shaped plate through two bearings. The outer surface of the rotating wheel contacts the inclined surface of the curved plate. The inner wall of the U-shaped plate is slidably connected to the outer surface of the curved plate.

[0010] By adopting the above technical solution, the double-sided tape storage tray stores the double-sided tape, and by using the cooperation of spring and U-shaped plate, the U-shaped plate can apply tension to the rotating wheel, so that the rotating wheel can contact the curved plate and clamp and position the double-sided tape.

[0011] Optionally, the cutting mechanism includes a square tube mounted on the upper surface of the curved plate. A sliding rod is slidably connected to the inner wall of the square tube. A first connecting seat is rotatably mounted at the bottom end of the sliding rod. An arc-shaped plate is rotatably mounted on the inner wall of the square tube. The right end of the arc-shaped plate is rotatably mounted to the bottom end of the first connecting seat via a pin. A second connecting seat is hinged to the left end of the arc-shaped plate via a pin. The top end of the second connecting seat is hinged to the inner top wall of the U-shaped plate. An L-shaped plate is fixedly mounted on the upper surface of the sliding rod. An installation groove is formed on the bottom surface of the L-shaped plate. A pressure roller is rotatably mounted on the inner wall of the installation groove via two bearings. A cutting blade is fixedly mounted on the right side of the L-shaped plate via bolts. The cutting blade is located above the pressure roller.

[0012] By adopting the above technical solution, through the cooperation of the first connecting seat, the second connecting seat and the arc plate, when the spring pushes the U-shaped plate to move upward, the slide rod can control the L-shaped plate to move downward, so that the mounting groove and the pressure roller apply pressure to the double-sided adhesive, sticking the double-sided adhesive to the cardboard box. When the pressure roller separates from the cardboard box, the pressure roller moves downward, so that the cutting blade cuts the double-sided adhesive during the downward movement.

[0013] Optionally, the adjustment mechanism includes a bracket mounted on the upper surface of the workbench. A servo motor is fixedly mounted on the front of the bracket. A groove is provided on the left side of the bracket. A perforated slider is slidably connected to the inner wall of the groove. A threaded rod is rotatably mounted on the inner wall of the groove through two bearings. The front end of the threaded rod is fixedly mounted to the output end of the servo motor. The left side of the perforated slider is fixedly mounted to the right side of the connecting plate.

[0014] By adopting the above technical solution, the servo motor can control the rotation of the threaded rod, which in turn drives the perforated slider to move. The perforated slider then moves the adhesive applicator back and forth, adjusting the position of the adhesive applicator.

[0015] Optionally, the conveying mechanism includes a drive motor mounted on the front of the workbench, and two rotating rollers are rotatably mounted on the inner wall of the workbench via two sets of bearings. The two rotating rollers are connected by a conveyor belt, and the output end of the drive motor is fixedly mounted to the front end of one of the rotating rollers.

[0016] Optionally, the threaded rod is located inside the perforated slider, and the threaded rod is threadedly connected to the inner wall of the perforated slider. A control panel is provided above the worktable, and the control panel is installed on the front of the adjustment mechanism.

[0017] Optionally, two limiting blocks are fixedly installed on both the front and back sides of the bent plate, and the sides of the two sets of limiting blocks that are close to each other are in contact with the left and right sides of the U-shaped plate.

[0018] By adopting the above technical solution, the limiting block limits the U-shaped plate, so that the U-shaped plate can only move up and down, effectively preventing the U-shaped plate from swinging.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The position of the adjustment mechanism can be adjusted by a servo motor, threaded rod, and perforated slider. The double-sided adhesive can be stored in the double-sided adhesive storage tray. The cooperation of spring and U-shaped plate can make the spring push the U-shaped plate to move upward, so that the U-shaped plate drives the rotating roller to move upward. The rotating roller, together with the curved plate, clamps the double-sided adhesive to prevent it from swinging. The cooperation of the first connecting seat, the second connecting seat, and the arc plate can make the spring move upward, so that the sliding rod can apply a downward pulling force, thereby making the L-shaped plate and the pressure roller move downward when separating from the cardboard box, which in turn drives the cutting blade to cut the double-sided adhesive, so as to facilitate the subsequent application of double-sided adhesive to the cardboard box and reduce the waste of double-sided adhesive.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a double-sided adhesive applicator for paper boxes. (Refer to...) Figure 1 A double-sided adhesive applicator for cardboard boxes includes a workbench 1, a conveying mechanism 2 inside the workbench 1, an adjusting mechanism 3 fixedly mounted on the upper surface of the workbench 1, and a control panel 6 mounted on the front of the adjusting mechanism 3. An adhesive applicator 4 is mounted on the adjusting mechanism 3 and driven by the adjusting mechanism 3. A cutting mechanism 5 for cutting the double-sided adhesive is located above the adhesive applicator 4, and the control structure of the cutting mechanism 5 is hinged to the adhesive applicator 4.

[0028] The conveying mechanism 2 can convey the cardboard box to the position below the adhesive applicator 4. The adjusting mechanism 3 can drive the adhesive applicator 4 to move so that it can be adjusted according to the position of the cardboard box. After the adhesive applicator 4 completes the application, the cutting mechanism 5 can cut the double-sided tape.

[0029] Reference Figure 1 and Figure 2 The conveying mechanism 2 includes a drive motor 201 installed on the front of the workbench 1. Two rotating rollers 203 are rotatably installed on the inner wall of the workbench 1 through two sets of bearings. The two rotating rollers 203 are connected by a conveyor belt 202. The output end of the drive motor 201 is fixedly installed to the front end of one of the rotating rollers 203.

[0030] By starting the drive motor 201, the rotating roller 203 can be driven to rotate. The two rotating rollers 203 can rotate synchronously through the conveyor belt 202, so that the conveyor belt 202 can transport the paper box raw materials.

[0031] Reference Figure 1 and Figure 2The adjustment mechanism 3 includes a bracket 301 mounted on the upper surface of the workbench 1. A servo motor 302 is fixedly mounted on the front of the bracket 301. A groove 303 is provided on the left side of the bracket 301. A perforated slider 305 is slidably connected to the inner wall of the groove 303. A threaded rod 304 is rotatably mounted on the inner wall of the groove 303 through two bearings. The front end of the threaded rod 304 is fixedly mounted to the output end of the servo motor 302. The left side of the perforated slider 305 is fixedly mounted to the right side of the connecting plate 402.

[0032] The servo motor 302 can control the rotation of the threaded rod 304, which in turn drives the perforated slider 305 to move. The perforated slider 305 then moves the adhesive applicator 4 back and forth, adjusting the position of the adhesive applicator 4.

[0033] Reference Figure 1 and Figure 2 The threaded rod 304 is located inside the perforated slider 305, and is threadedly connected to the inner wall of the perforated slider 305. The adhesive applicator 4 is mounted on the perforated slider 305.

[0034] The threaded rod 304 can drive the perforated slider 305 to move, so that the perforated slider 305 can move back and forth along the groove 303, thereby driving the adhesive applicator 4 to move.

[0035] Reference Figure 2 and Figure 3 The adhesive applicator 4 includes a double-sided adhesive storage tray 401. A connecting plate 402 is fixedly installed on the right side of the double-sided adhesive storage tray 401. A curved plate 403 is fixedly installed on the bottom surface of the connecting plate 402. A spring 404 is fixedly installed on the upper surface of the curved plate 403. A U-shaped plate 405 is fixedly installed on the top of the spring 404.

[0036] Reference Figure 3 and Figure 4 The inner wall of the U-shaped plate 405 is rotatably mounted with a rotating wheel 406 via two bearings. The outer surface of the rotating wheel 406 is in contact with the inclined surface of the bent plate 403, and the inner wall of the U-shaped plate 405 is slidably connected to the outer surface of the bent plate 403.

[0037] The double-sided tape can be stored in the double-sided tape storage tray 401, and the U-shaped plate 405 can be used to apply a pulling force to the rotating wheel 406 by the cooperation of the spring 404 and the U-shaped plate 405, so that the rotating wheel 406 can contact the curved plate 403 to clamp and position the double-sided tape.

[0038] Reference Figure 3Two limiting blocks 7 are fixedly installed on both the front and back of the curved plate 403. The sides of the two sets of limiting blocks 7 that are close to each other are in contact with the left and right sides of the U-shaped plate 405. The limiting blocks 7 can limit the U-shaped plate 405, so that the U-shaped plate 405 can only move up and down, effectively preventing the U-shaped plate 405 from swinging.

[0039] Reference Figure 3 and Figure 4 The cutting mechanism 5 includes a square tube 501 mounted on the upper surface of the curved plate 403. A slide rod 502 is slidably connected to the inner wall of the square tube 501. A first connecting seat 505 is rotatably mounted at the bottom end of the slide rod 502. An arc plate 509 is rotatably mounted on the inner wall of the square tube 501. The right end of the arc plate 509 is rotatably mounted to the bottom end of the first connecting seat 505 via a pin. A second connecting seat 508 is hinged to the left end of the arc plate 509 via a pin. The top end of the second connecting seat 508 is hinged to the inner top wall of the U-shaped plate 405. An L-shaped plate 503 is fixedly mounted on the upper surface of the slide rod 502. An installation groove 506 is opened on the bottom surface of the L-shaped plate 503. A pressure roller 507 is rotatably mounted on the inner wall of the installation groove 506 via two bearings. A cutting blade 504 is fixedly mounted on the right side of the L-shaped plate 503 via bolts. The cutting blade 504 is located above the pressure roller 507.

[0040] With the cooperation of the first connecting seat 505, the second connecting seat 508 and the arc plate 509, when the spring 404 pushes the U-shaped plate 405 to move upward, the slide rod 502 can control the L-shaped plate 503 to move downward, so that the mounting groove 506 and the pressure roller 507 can apply pressure to the double-sided adhesive, sticking the double-sided adhesive to the cardboard box. When the pressure roller 507 separates from the cardboard box, the pressure roller 507 moves downward, so that the cutting blade 504 cuts the double-sided adhesive during the downward movement.

[0041] The implementation principle of the double-sided adhesive applicator for paper boxes according to this application embodiment is as follows: During use, double-sided adhesive is placed inside the double-sided adhesive storage tray 401 and pulled so that it passes between the rotating wheel 406 and the bending plate 403, and wraps around to the bottom of the pressure roller 507. With the start of the drive motor 201, the drive motor 201 drives the rotating roller 203 to rotate, which in turn drives the conveyor belt 202 to rotate, thereby conveying the paper box material. Then, the servo motor 302 is started, causing the threaded rod 304 to rotate, which in turn controls the sliding of the perforated slider 305, adjusting the position of the applicator mechanism 4. As the paper box moves to the bottom of the bending plate 403, the pressure roller 507 moves to the top of the paper box and applies the double-sided adhesive. During the upward movement of the U-shaped plate 405 pushed by the spring 404, the first connecting seat 505 and the second connecting seat 507 can... The seat 508 and the arc-shaped plate 509 apply a pulling force to the slide rod 502, causing the slide rod 502 to drive the L-shaped plate 503 downward, so that the pressure roller 507 can apply pressure to the double-sided tape, firmly sticking the double-sided tape to the cardboard box. As the cardboard box moves, the cardboard box can pull the double-sided tape, causing the double-sided tape inside the double-sided tape storage tray 401 to rotate, pulling out the double-sided tape. At the same time, the double-sided tape drives the rotating wheel 406 to rotate, and the rotating wheel 406 can cooperate with the curved plate 403 to press the double-sided tape. The clamping mechanism prevents the double-sided adhesive from swinging. As the cardboard box moves to the right side of the pressure roller 507, when the pressure roller 507 separates from the cardboard box, the spring 404 pushes the U-shaped plate 405 upward. During this process, the first connecting seat 505, the second connecting seat 508, and the arc plate 509 apply tension to the slide rod 502, allowing the pressure roller 507 to fall quickly. This, in turn, drives the cutting blade 504 to cut the double-sided adhesive on the cardboard box, facilitating the subsequent application of adhesive to the cardboard box.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
