Description

Technical Field

[0001] This application relates to the field of enclosure processing, and in particular to an automatic adhesive application enclosure sealing device. Background Technology

[0002] In the modern logistics and packaging industry, cardboard boxes are the mainstream packaging containers, and their packaging process directly affects the stability and safety of goods during transportation.

[0003] Automatic glue-applying box sealing device is a device that uses an automated system to apply glue and then press the box together to allow the glue to fully solidify and complete the assembly of the box. However, traditional sealing methods use rigid contact mechanisms such as pressure rollers and cylinder pressure plates to ensure that the sealing medium is fully adhered to the box. This rigid method can easily lead to uneven spreading of the sealing medium during the packaging process due to the inability to control the pressure, and can also easily cause damage to the packaging area. Utility Model Content

[0004] In order to improve the traditional sealing method, which uses rigid contact mechanisms such as pressure rollers and cylinder pressure plates to fully adhere the sealing medium to the box, this application provides an automatic glue-applying box sealing device. This is because such rigid methods are prone to causing uneven spreading of the sealing medium due to uncontrollable pressure during the packaging operation, and are also prone to damage to the packaging area.

[0005] The automatic glue-applying box sealing device provided in this application adopts the following technical solution: An automatic adhesive-applying box sealing device includes a sliding frame with two symmetrical sliding blocks slidably arranged inside. Connecting arms are symmetrically arranged at the bottom end of the sliding frame. The bottom ends of both sliding blocks are connected to the top ends of their respective connecting arms. A connecting frame is installed at the bottom end of each connecting arm, and a connecting plate is installed at the bottom end of the connecting frame. A water storage tank is installed through the top end of the connecting plate. A balloon block is located below the water storage tank, with the bottom end of the water storage tank contacting the top end of the balloon block. A rolling shaft is installed inside the balloon block, and the balloon block is wrapped around the outside of the rolling shaft. An mounting arm is located on one side of the rolling shaft, and one end of the rolling shaft is hinged to the side wall of the mounting arm. A transmission screw sleeve is installed through the interior of each sliding block. A bidirectional screw is rotatably connected inside the sliding frame, and transmission screw sleeves are symmetrically threaded onto the outer side wall of the bidirectional screw. A motor is installed on the side wall of the sliding frame, and the output end of the motor is connected to one end of the bidirectional screw.

[0006] By adopting the above technical solution, the sliding block moves relative to each other inside the sliding frame, and by changing the tilt angle of the two connecting arms, the connecting frame and other components move vertically downward. At the same time, the liquid inside the water tank is heated to a specified temperature, thereby transferring heat. During the rotation of the rolling shaft and the balloon block, the balloon block absorbs heat due to the contact between its top and bottom, giving it a certain amount of heat. When the balloon block is attached to the sealing area of ​​the automatically applied glue box, the glue can be spread more effectively. Through the output of the motor, the bidirectional lead screw rotates synchronously, and the bidirectional lead screw and the transmission lead screw sleeve form a lead screw transmission structure, driving the sliding block to move relative to each other inside the sliding frame, thereby causing the first mounting frame to move synchronously, thus changing the tilt angle of the connecting arm.

[0007] Preferably, a first mounting bracket is installed at the bottom end of each of the two sliding blocks, and a second mounting bracket is symmetrically installed at the top end of the connecting bracket. The top end of each connecting arm is hinged to the interior of the bottom end of the corresponding first mounting bracket, and the bottom end of each connecting arm is hinged to the interior of the top end of the corresponding second mounting bracket.

[0008] By adopting the above technical solution, and by changing the tilt angle of the two connecting arms, the connecting frame can move vertically downward, thereby adapting to the vertical height of the housing.

[0009] Preferably, sliding sleeves are installed on both sides of the connecting plate, and upright plates are symmetrically installed at the bottom of the sliding frame, with the sliding sleeves fitted onto the outer side wall of the upright plates.

[0010] By adopting the above technical solution, when the connecting frame and connecting plate are adapted to the vertical height of the box, the connecting plate, together with the sliding sleeves fixed on both sides, moves vertically on the outer side wall of the upright plate, making the connecting frame and connecting plate more stable when adapted to the vertical height of the box.

[0011] Preferably, electric heaters are symmetrically installed at the rear end of the water storage tank.

[0012] By adopting the above technical solution, the liquid inside the water storage tank is heated by an electric heater, thereby heating the liquid inside the water storage tank to a certain temperature.

[0013] Preferably, the front outer wall of the connecting plate is provided with a movable groove, and the movable groove is movably connected to the bottom of the movable block, which is provided with an mounting arm.

[0014] By adopting the above technical solution, the moving block moves inside the moving groove, thereby making the rolling shaft and the ball block correspond to the sealing area of ​​the box that is automatically coated with glue.

[0015] Preferably, the outer side wall of the movable block is symmetrically provided with grooves, and flexible sheets are installed inside each groove. First limiting protrusions are installed at equal intervals on the outer wall of one end of each flexible sheet.

[0016] By adopting the above technical solution and using the flexible sheet, when the first limiting protrusion is under pressure during use, the flexible sheet deforms, and after the second limiting protrusion and the first limiting protrusion are released from pressure, the flexible sheet deforms and drives the first limiting protrusion to reset.

[0017] Preferably, the inner walls of the front and rear ends of the movable groove are each provided with a second limiting protrusion at equal intervals, and the outer side wall of the second limiting protrusion abuts against the outer side wall of the first limiting protrusion.

[0018] By adopting the above technical solution, the outer wall of the second limiting protrusion abuts against the outer wall of the first limiting protrusion, thereby limiting the movable block to be self-positioned inside the movable groove.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This utility model uses a balloon block that wraps around a rolling shaft as a sealing execution component. The balloon block is filled with liquid, and when it comes into contact with the sealing area of ​​the box, it can adaptively adjust the pressure according to the surface shape of the box. This avoids the problems of insufficient pressure causing the adhesive to not spread evenly and not sticking tightly, while also preventing excessive pressure from causing deformation and damage to the box. It achieves flexible and effective pressure control. Furthermore, the liquid can be heated to a specified temperature according to the type of adhesive. The heat is transferred to the balloon block through a water tank, which enables the balloon block to assist the adhesive to spread quickly and promote solidification during rolling sealing, reducing the generation of air bubbles and gaps, and further improving the sealing performance. At the same time, it avoids the situation where the poor fluidity of the adhesive affects the sealing effect in low-temperature environments. 2. This utility model describes a device that uses a motor to drive a bidirectional lead screw to rotate. Utilizing the lead screw transmission structure of the bidirectional lead screw and the transmission lead screw sleeve, the sliding block slides relative to the sliding frame, thereby changing the tilt angle of the connecting arm and achieving vertical height adjustment between the connecting frame and the connecting plate. This allows for precise adaptation to the sealing requirements of boxes with different height specifications, ensuring that the rolling shaft and the ball block are always aligned with the box sealing area, laying the foundation for subsequent stable sealing operations. This improves the practicality and convenience of the device, and allows for rapid adjustment of the rolling shaft and ball block positions based on the automatically applied glue sealing area of ​​the box. This method effectively enhances the practicality of the device and avoids limitations in operation. Attached Figure Description

[0022] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0023] This application discloses an automatic glue-applying box sealing device.

[0024] Reference Figures 1-4 An automatic glue-applying box sealing device includes a sliding frame 1. A bidirectional lead screw 4 is rotatably connected between the inner sidewalls of the sliding frame 1. The teeth on the outer walls of the two ends of the bidirectional lead screw 4 are arranged with opposite structures. A motor 5 is fixedly connected to one outer wall of the sliding frame 1. The output end of the motor 5 passes through the side wall of the sliding frame 1 and is fixedly connected to one end of the bidirectional lead screw 4. A transmission lead screw sleeve 3 is symmetrically meshed with the outer wall of the bidirectional lead screw 4. A sliding block 2 is fixedly connected to the outside of the transmission lead screw sleeve 3. The two sliding blocks 2 are symmetrically slidably connected inside the sliding frame 1. A connecting frame 9 is provided below. The bottom end of the sliding block 2 is fixedly connected to the first mounting frame 6. The top end of the connecting frame 9 is symmetrically fixedly connected to the second mounting frame 8. A connecting arm 7 with an "eight" shaped structure is provided between the bottom of the sliding frame 1 and the top of the connecting frame 9. The top end of the connecting arm 7 is hinged to the bottom end of the corresponding first mounting frame 6, and the bottom end of the connecting arm 7 is hinged to the top end of the corresponding second mounting frame 8. The motor 5 is a worm gear reducer motor, and the specific model of the motor 5 is NFP-5840-31ZYS-S.

[0025] During the sealing operation of the automatically glued box, the adaptation operation is completed according to the vertical height of the box to be processed. Specifically, the motor 5 outputs the operation, causing the bidirectional lead screw 4 to rotate synchronously, so that the bidirectional lead screw 4 and the transmission lead screw sleeve 3 form a lead screw transmission structure, driving the sliding block 2 to move relative to each other inside the sliding frame 1, thereby causing the first mounting frame 6 to move synchronously. This changes the tilt angle of the connecting arm 7. By changing the tilt angle of the two connecting arms 7, the connecting frame 9 moves vertically downward, thereby completing the adaptation of the vertical height of the box.

[0026] Reference Figures 1-3 A connecting plate 10 is fixedly connected to the bottom of the connecting frame 9. Sliding sleeves 11 are symmetrically fixedly connected to the outer walls of both sides of the connecting plate 10. A vertical plate 12 is symmetrically fixedly connected to the bottom of the sliding frame 1. The sliding sleeves 11 are vertically slidably connected to the outer wall of the vertical plate 12. A water storage tank 13 is fixedly connected through the inside of the connecting plate 10. An electric heater 14 is symmetrically fixedly connected through the rear end of the water storage tank 13.

[0027] When the connecting frame 9 and connecting plate 10 are adapted to the vertical height of the box, the connecting plate 10, together with the sliding sleeves 11 fixed on both sides, moves vertically on the outer side wall of the upright plate 12, making the connecting frame 9 and connecting plate 10 more stable when adapted to the vertical height of the box. During the automatic glue application and box sealing operation, depending on the glue material applied by the automatic glue application, the liquid inside the water tank 13 can be selectively heated by the electric heater 14 to heat the liquid inside the water tank 13 to a specified temperature, thereby carrying out heat transfer and better performing the box sealing operation.

[0028] Reference Figure 1 , Figure 5 and Figure 6 The front end of the connecting plate 10 is fixedly connected to a movable groove 15. The movable groove 15 is movably connected to a movable block 16. The front and rear ends of the movable block 16 are provided with grooves. The interior of each groove is fixedly connected to a flexible sheet 17. The outer wall of one end of the flexible sheet 17 is fixedly connected to a first limiting protrusion 18 at equal intervals. The inner wall of the front end and the inner wall of the rear end of the movable groove 15 are fixedly connected to a second limiting protrusion 19 at equal intervals. The outer wall of the second limiting protrusion 19 abuts against the outer wall of the first limiting protrusion 18. The bottom end of the movable block 16 is fixedly connected to an "L"-shaped mounting arm 20. One end of the mounting arm 20 is hinged to a rolling shaft 21. The outer side of the rolling shaft 21 is wrapped with a balloon block 22. The interior of the balloon block 22 is filled with liquid. The balloon block 22 is made of soft silicone material.

[0029] According to the sealing area of ​​the automatically glued box, the movable block 16 moves inside the movable groove 15, thereby aligning the rolling shaft 21 and the ball-shaped block 22 with the sealing area of ​​the automatically glued box. After the movable block 16 moves inside the movable groove 15, it is connected to a flexible sheet. During use, when the second limiting protrusion presses against the first limiting protrusion, the flexible sheet deforms. After the second limiting protrusion releases from the first limiting protrusion, the flexible sheet deforms again, causing the first limiting protrusion to reset. This causes the outer wall of the second limiting protrusion 19 to abut against the outer wall of the first limiting protrusion 18, thus self-limiting the movable block 16 inside the movable groove 15. Simultaneously, the rotation of the rolling shaft 21 and the ball-shaped block 22 seals the automatically glued box. Because the ball-shaped block 22 presses against the sealing area of ​​the automatically glued box... This design provides adaptability during sealing operations, improving sealing effectiveness. The connecting arm 7 allows for vertical downward adjustment, ensuring the balloon block 22 contacts the sealing area. The contact force can be adjusted according to the box material, maintaining stable pressure and preventing box deformation. This ensures thorough adhesive adhesion, avoiding air bubbles or gaps that could allow gas or liquid to enter the box, damaging or contaminating stored items. Furthermore, as the rolling shaft 21 and balloon block 22 rotate, the top of the balloon block 22 contacts the bottom of the water tank 13, absorbing heat and allowing it to spread better when automatically applying adhesive to the sealing area, thus enhancing the sealing effect.

[0030] The implementation principle of the automatic glue-applying box sealing device in this application embodiment is as follows: First, the adaptation operation is completed according to the vertical height of the box to be processed. Specifically, the motor 5 outputs the operation, causing the bidirectional lead screw 4 to rotate synchronously, so that the bidirectional lead screw 4 and the transmission lead screw sleeve 3 form a lead screw transmission structure, driving the sliding block 2 to move relative to each other inside the sliding frame 1, thereby causing the first mounting frame 6 to move synchronously. This changes the tilt angle of the connecting arm 7. By changing the tilt angle of the two connecting arms 7, the connecting frame 9 moves vertically downward, and the rolling shaft 21 and the ball block 22 correspond to the automatic glue-applying box sealing area. Secondly, depending on the adhesive material applied automatically, the liquid inside the water tank 13 can be selectively heated by the electric heater 14 to a specified temperature. Subsequently, the movable block 16 moves inside the movable groove 15, thereby aligning the rolling shaft 21 and the ball block 22 with the automatically glued box sealing area. Finally, the automatic glue-applying box is sealed by the rotation of the rolling shaft 21 and the balloon block 22. Because the balloon block 22 squeezes the sealing area of ​​the automatic glue-applying box, it has a certain adaptability during the sealing operation. This can improve the sealing effect, ensure that the glue is fully adhered, and avoid the formation of air bubbles or gaps. This prevents gas or liquid from entering the box and causing damage or contamination to the stored items. During the rotation of the rolling shaft 21 and the balloon block 22, the top of the balloon block 22 abuts against the bottom of the water storage tank 13, allowing the balloon block 22 to absorb heat. This heat allows the balloon block 22 to better spread the glue when it adheres to the sealing area of ​​the automatic glue-applying box, improving the sealing effect. This completes the use of the automatic glue-applying box sealing device.
