Description

Technical Field

[0001] The invention relates to the technical field of glue painting equipment, and in particular to a glue painting device for packaging gift boxes which can be evenly applied. Background Art

[0002] In the manufacture of the packaging gift box, a sponge pad, an internal flexible cushion layer and other structures are also provided on the inner side of the packaging gift box. The inner side of the packaging gift box is first coated with glue by a glue painting device, and then fixed by glue and a sponge pad.

[0003] After the gluing head of the gluing device finishes gluing one packaging box, it continues to move a certain distance to glue the next packaging box. After moving a long distance, water droplets of glue will accumulate at the lower end of the gluing head of the gluing device, resulting in more glue when the gluing head starts to glue than in the subsequent movement. After the gluing head stops after gluing, the glue at the tail end of the gluing head will release more glue. There is still a lot of room for improvement in the uniformity of gluing. Summary of the invention

[0004] The disclosed embodiment relates to a glue painting device for packaging gift boxes that can be evenly applied. When the packaging box is switched to perform a long-distance overhead movement without glue discharge, the upper piston block moves upward to inhale, and the airflow simultaneously drives the inner sealing piston to move along the upper connecting groove. The inner sealing piston fits the inner wall of the upper connecting groove and moves upward to generate a certain suction force, which can suck up the glue of the mixing cone tube and the glue painting head, and prevent the glue of the glue painting head from overflowing downward, resulting in a large amount of glue flowing out of the glue painting head when it is used after a long-distance movement, and water droplets of glue accumulate at the lower end of the glue painting head, resulting in more glue at the beginning of glue coating, thereby enhancing the uniformity of glue discharge from the glue painting head. When the glue painting head stops moving at the end of glue discharge, the upper piston block moves upward to inhale, reducing the amount of glue discharged by the glue painting head at the end of glue discharge, and avoiding the situation that the amount of glue discharged after the glue painting head stops moving is concentrated into a large point than during the movement, and the tail end of the glue discharge after stopping will discharge more glue than the middle moving part, resulting in uneven glue discharge.

[0005] According to a first aspect of the present disclosure, there is provided a glue device for packaging gift boxes that can be evenly applied, specifically comprising: a glue head frame, an upper lifting and moving frame, a lateral moving frame, a longitudinal moving frame, a piston tube and a mixing conical tube, wherein an upper lifting and moving frame is arranged above the glue head frame, the upper lifting and moving frame and the lateral moving frame are slidably connected in a vertical direction, the lateral moving frame and the longitudinal moving frame are slidably connected in a horizontal direction, a piston tube and a mixing conical tube are arranged below the upper lifting and moving frame, a glue head is fixedly arranged at the bottom of the glue head frame, a limiting slot is arranged in an annular array at the upper part of the glue head frame, and the limiting slot and the lower end of the limiting pin are slidably connected.

[0011] In at least some embodiments, the upper air outlet pipe of the upper connecting groove is connected and fixed, and the top end of the second connecting tension spring is fixedly connected to the air outlet pipe. The second connecting tension spring pulls the inner sealing piston upward, and the top surface of the inner sealing piston and the upper connecting groove are sealed.

During cleaning, it can also reduce the residual cleaning fluid inside the mixing cone tube, reducing the maintenance burden of personnel.

[0015] When the packaging box is switched to move over a long distance without discharging glue, the upper piston block moves upward to inhale air, and the airflow will drive the inner sealing piston to move along the upper connecting groove at the same time. The inner sealing piston fits against the inner wall of the upper connecting groove and moves upward to generate a certain suction force, which can suck up the glue of the mixing cone tube and the glue painting head to prevent the glue from overflowing downward, resulting in a large amount of glue flowing out of the glue painting head when it is used after moving over a long distance, and water droplets of glue will accumulate at the lower end of the glue painting head, resulting in more glue at the beginning of gluing, thereby enhancing the uniformity of glue dispensing from the glue painting head.

[0016] When the glue dispensing head stops moving at the end of glue dispensing, the upper piston block moves upward to inhale, reducing the amount of glue dispensing by the glue dispensing head at the end of glue dispensing, avoiding the situation where the amount of glue dispensing after the glue dispensing head stops moving at the end of glue dispensing is concentrated into a large point than during the movement, and the tail end of the glue dispensing head after stopping will dispense more glue than the moving part in the middle, resulting in uneven glue dispensing, more uniform glue coating lines, and less excess glue.

[0017] The booster air pump pressurizes the glue box to export the glue. Compared with screw pumps, it eliminates the direct contact between the pump and the glue, reducing the burden of glue cleaning in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS

The lower fixed platform 402 drives the longitudinal moving frame 4 to move longitudinally through the displacement chain 401, and the longitudinal moving frame 4 drives the transverse moving frame 3 to move transversely through the displacement chain 401, so as to realize the transverse and longitudinal displacement of the gluing position of the packaging box. The piston tube 5 and the mixing cone tube 6 are arranged below the upper lifting moving frame 2, and the upper piston block 501 is slidingly arranged inside the piston tube 5, and the outer side of the piston tube 5 is fixedly provided with an outer telescopic cylinder 502, and the lower two parts of the piston tube 5 The lower air inlet pipe 503 and the air outlet pipe 506 are respectively connected to the sides, an inner one-way sealing block 504 is axially slidably arranged on the inner side of the lower air inlet pipe 503, a first connecting tension spring 505 is fixedly arranged between the inner one-way sealing block 504 and the lower air inlet pipe 503, an inner spiral strip 601 is fixedly arranged inside the mixing conical tube 6, a lower connecting frame 602 is fixedly arranged on the outer side of the mixing conical tube 6, glue inlet pipes 603 are arranged on both sides of the top of the mixing conical tube 6, an upper connecting groove 604 is arranged on the inner top of the mixing conical tube 6, an inner sealing piston 605 is slidingly arranged on the inner side, and a second connecting tension spring 606 is fixedly arranged on the top of the inner sealing piston 605.

[0023] In the disclosed embodiment, the upper piston block 501 is fixedly connected to the telescopic rod of the outer telescopic cylinder 502, the first connecting tension spring 505 pulls the inner one-way sealing block 504 downward to fit with the lower air inlet pipe 503 to maintain a seal, the piston tube 5 and the lower part of the rotating connecting frame 203 are fixedly connected, the upper piston block 501 pushes the gas inside the piston tube 5 into the mixing conical tube 6, and the gas pushes out the residual glue in the mixing conical tube 6. The repeated movement and exhaust of the upper piston block 501 pushes the residual glue inside the mixing conical tube 6 to flow downward, thereby reducing the residual glue inside the mixing conical tube 6.

[0024] In the disclosed embodiment, the upper end of the lower connecting frame 602 is fixedly connected to the piston tube 5, the lower part of the lower connecting frame 602 is rotatably connected with the upper rotating shaft of the glue head frame 1, the middle part of the limit pin 103 and the lower part of the lower connecting frame 602 are penetrated and slidably connected, the lower end of the mixing conical tube 6 is connected to the glue head 101 through a hose, the glue head frame 1 rotates to one side along the connecting shaft between the glue head frame 1 and the lower connecting frame 602, the limit pin 103 and the limit slot 102 on the outside of the glue head frame 1 are slidably inserted to complete the angle limiting operation, the glue head frame 1 and the glue head 101 are tilted forty-five degrees to facilitate the gluing process on the vertical surface of the packaging box.

[0025] In the embodiment of the present disclosure, the upper air outlet pipe 506 of the upper connecting groove 604 is connected and fixed, and the top end of the second connecting tension spring 606 is fixedly connected to the air outlet pipe 506. The second connecting tension spring 606 pulls the inner sealing piston 605 upward, and the top surface of the inner sealing piston 605 is sealed with the upper connecting groove 604. The inner sealing piston 605 moves along the upper connecting groove 604, and the inner sealing piston 605 moves upward against the inner wall of the upper connecting groove 604 to produce a piston effect. The upper connecting groove 604 generates an upward suction force to suck up the glue of the mixing conical tube 6 and the glue head 101, so as to avoid the glue of the glue head 101 from overflowing downward during the movement, and the glue beads are generated at the lower end of the glue head 101, which causes more than the normal amount of glue to flow out when the glue head 101 starts to be used for glue coating.

[0026] In the disclosed embodiment, an electric lifting screw 301 is rotatably provided in the middle of the transverse moving frame 3, and the electric lifting screw 301 is driven to rotate by a motor. A glue box 302 is fixedly provided on the upper part of the transverse moving frame 3, and the bottom of the glue box 302 is connected to the glue inlet pipe 603 and a solenoid valve is provided. A booster air pump 303 is fixedly provided on the upper part of the transverse moving frame 3, and the upper part of the glue box 302 is connected to the air outlet of the booster air pump 303. The booster air pump 303 pressurizes the air injected into the glue box 302 to realize the glue export work. Compared with the screw pump and other methods, the booster air pump 303 does not contact the glue vertically, thereby eliminating the maintenance and cleaning burden after direct contact with the glue.

[0027] Embodiment 2, based on embodiment 1, the booster air pump 303 is also not set, the glue tank 302 is connected to the glue inlet pipe 603 through the screw extruder, and the setting of the solenoid valve is eliminated, thereby achieving compatibility with the existing screw extruder glue conveying equipment, and facilitating the transformation and upgrading of the existing equipment.

[0028] The working principle of this embodiment is as follows: glue is stored inside the glue box 302, and two independent spaces are arranged inside the glue box 302 for independent storage of ab glue. The booster air pump 303 inflates and pressurizes the glue box 302. The glue inside the glue box 302 enters the glue inlet pipe 603 and the mixing cone tube 6 along the hose and the solenoid valve under pressure. The inner spiral strip 601 in the mixing cone tube 6 promotes the mixing of ab glue. The glue inside the mixing cone tube 6 flows downward to the painting glue head 101, and the painting glue head 101 flows to the packaging box below. The booster air pump 303 fills the glue box 302 with air to pressurize it. For the work of exporting water, compared with the screw pump and other methods, the booster air pump 303 does not contact the glue vertically, eliminating the direct contact between the pump and the glue, reducing the glue cleaning burden of the pump in the later stage, and reducing the maintenance burden. The glue drawing head 101 is in a vertical state to draw glue on the bottom plane of the packaging box. However, when it is necessary to apply glue to the inner side of the packaging box, the glue head frame 1 rotates to one side along the connecting axis between the glue head frame 1 and the lower connecting frame 602, and the limit pin 103 and the limit slot 102 on the outer side of the glue head frame 1 are slid and inserted, and the glue head frame 1 and the glue drawing head 101 are adjusted to be tilted forty-five degrees, and the visual module 201 performs visual monitoring of the moving path; The lower fixed stand 402 drives the longitudinal moving stand 4 to move longitudinally through the displacement chain 401, and the longitudinal moving stand 4 drives the transverse moving stand 3 to move transversely through the displacement chain 401. The transverse moving stand 3 drives the upper lifting and moving stand 2 to move in the vertical direction through the electric lifting screw 301, so as to realize the displacement operation along the position where the packaging box needs to be glued; a plurality of packaging boxes are placed on the workbench in the middle of the lower fixed stand 402 for glue application operation one by one. When it is necessary to move the packaging box overhead for a long distance without glue discharge, the solenoid valve connected to the glue tank 302 is closed, and the outer telescopic cylinder 502 drives the upper piston block 501 to move upward. When the upper piston block 501 moves upward, the piston tube 5 is inhaled, and the airflow of the upper piston block 501 will drive the inner sealing piston 605 to move along the upper connecting groove 604 at the same time. The inner sealing piston 605 moves upward against the inner wall of the upper connecting groove 604 to produce a piston effect, and the upper connecting groove 604 generates an upward suction force. The upper connecting groove 604 sucks up the glue of the mixing cone tube 6 and the glue head 101 to prevent the glue of the glue head 101 from overflowing downward during the movement. There is a glue bead at the lower end of the glue head 101. After a long distance of movement, a large amount of glue will flow out to the packaging box when the glue head 101 starts to be used for glue application, resulting in more glue at the beginning of glue application, thereby enhancing the uniformity of glue application of the glue head 101; When the equipment needs to be shut down, the lower air inlet pipe 503, the inner one-way sealing block 504 and the first connecting tension spring 505 form a one-way structure, and air can only be taken in from the lower air inlet pipe 503 to the piston tube 5 from the outside. The upper piston block 501 moves downward, and external air enters from the lower air inlet pipe 503. The upper connecting groove 604, the inner sealing piston 605 and the second connecting tension spring 606 also form a one-way structure. The upper connecting groove 604 is connected to the piston tube 5 for one-way air discharge. The upper piston block 501 pushes the gas inside the piston tube 5 into the mixing cone tube 6, and the gas pushes out the residual glue in the mixing cone tube 6. The repeated movement of the upper piston block 501 to discharge air further reduces the residual glue in the mixing cone tube 6. During cleaning, the piston tube 5 discharges air toward the mixing cone tube 6, which can also reduce the residual cleaning liquid inside the mixing cone tube 6 and reduce the maintenance burden of personnel. When the glue painting head 101 stops moving at the end of glue dispensing, the upper piston block 501 moves upward to inhale, thereby reducing the amount of glue dispensing by the glue painting head 101 at the end of glue dispensing, and avoiding the situation where the glue dispensing amount after the glue painting head 101 stops moving at the end of glue dispensing is greater than that during movement, resulting in the glue dispensing of the glue painting head 101 being concentrated into a large point after the glue painting head 101 stops moving, and the tail end of the glue dispensing after stopping will dispense more glue than the moving middle part, resulting in uneven glue dispensing, thereby improving the uniformity of the glue coating line and reducing unnecessary waste of glue.
