Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging box production technology, specifically relating to a glue spraying machine for paper packaging box production. Background Technology
[0002] A glue spraying machine for paper packaging box production is an automated glue application device used to precisely spray adhesive during the paper box forming process, achieving efficient bonding and sealing. Its core function is to replace traditional manual or roller-based glue application, improving the efficiency, quality, and cost-effectiveness of packaging production through intelligent control of glue quantity, position, and speed.
[0003] Chinese patent document CN222844905U discloses a glue spraying machine for processing paper boxes. The machine uses a pusher plate that moves with the conveyor belt to move the paper packaging box, which is centered by the positioning frame and other components, to the bottom of the processing frame. Then, the pumped adhesive is sprayed onto all corners of the paper packaging box by the nozzle with variable horizontal position and height, thus completing all-round glue spraying.
[0004] However, in the existing technology, when paper packaging boxes are simply centered and transported to the glue spraying station, they are prone to positioning deviations that prevent them from stopping accurately, which in turn causes the adhesive to be unable to be sprayed accurately onto the target area. Therefore, a glue spraying machine for paper packaging box production is proposed. Utility Model Content

[0006] The technical solution adopted in this utility model is as follows:

A glue spraying component is provided above the feeding component that can spray adhesive onto the paper packaging boxes. Positioning components are provided in front of and behind the feeding component that can stop the transported paper packaging boxes and make them accurately stop at the glue spraying station.
[0008] The feeding assembly includes a worktable;
[0009] The positioning components include clamps that can make multi-point contact with the paper packaging box conveyed to the glue spraying station to fully limit its positioning;
[0010] The clamping component includes two longitudinally identical blocking blocks set on the workbench surface. A support rod is fixedly connected above the blocking blocks. A bending block is set on one side of the blocking blocks. A multi-stage telescopic rod is fixedly connected to one side of the bending block. A longitudinal moving block is fixedly connected between the two multi-stage telescopic rods.
[0011] The positioning assembly also includes a control component that can switch the horizontal position of the blocking block according to the specifications of the paper packaging box and the needs of conveying and spraying glue, and an adjustment component that can adjust the clamping force of the longitudinal block on the paper packaging box.
[0012] Preferably, the control component includes a limiting sub-frame fixedly installed on the workbench surface, a limiting main frame fixedly connected to the side of the limiting sub-frame near the longitudinal moving block, a sliding rod movably connected to the blocking block is provided between the limiting sub-frame and the limiting main frame, a positioning cylinder is provided on one side of the sliding rod between the blocking block and the limiting main frame, and a connecting handle is provided on the other side of the sliding rod between the blocking block and the limiting main frame.
[0013] Preferably, the adjusting component includes two limiting rods fixedly connected to the side of the longitudinal moving block near the limiting sub-frame, a thrust bracket movably connected between the two limiting rods, a screw rod movably connected in front of the thrust bracket, and a spring movably connected to the limiting rods between the longitudinal moving block and the thrust bracket.
[0014] Preferably, both the blocking block and the support rod are slidably connected to the bending block.
[0015] Preferably, the blocking block, the limiting subframe, and the limiting main frame are all slidably connected to the sliding rod, and the positioning cylinder and the connecting handle are rotatably connected to the blocking block and the limiting main frame.

[0017] The beneficial effects of this utility model are as follows: by setting two sets of positioning components at the glue spraying station of this glue spraying machine, the blocking block whose horizontal and vertical positions can be changed by the control components during movement, and the longitudinal moving block whose vertical position can be changed by the adjustment components and the blocking block, can work together to intercept and accurately position the paper packaging box being transported at the glue spraying station, thereby ensuring that the glue spraying components accurately spray glue to the target area.

[0027] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0028] like Figures 1-4 As shown, a glue spraying machine for paper packaging box production includes a feeding component 1 that can transport paper packaging boxes to be glued to the glue spraying station. A glue spraying component 2 is provided above the feeding component 1 that can spray adhesive onto the paper packaging boxes. Positioning components 3 are provided in front of and behind the feeding component 1 to stop the transported paper packaging boxes and make them accurately stop at the glue spraying station.
[0029] In this embodiment: the feeding assembly 1 includes a workbench 101, and roller seats 102 are fixedly installed on both the front and rear sides of the workbench 101. A rotating roller 103 is movably connected between two roller seats 102 with the same lateral position. A conveyor belt 104 is arranged between the two rotating rollers 103. A motor 105 is fixedly connected to the rear end of one of the rotating rollers 103. Inspection plates 106 are fixedly connected to both sides of the workbench 101.
[0030] Roller seat 102 is rotatably connected to roller 103;
[0031] The workbench 101 provides installation positions for components such as roller seat 102, motor 105, horizontal linear guide rail 201, and limit sub-frame 306. The conveyor belt 104 is installed by the rotating rollers 103 mounted on both sides of the workbench 101 by the roller seat 102. The rotating rollers 103 connected to the motor 105 drive the conveyor belt 104 and another rotating roller 103 to rotate after the motor 105 is running. The inspection plate 106 makes it easy for workers to maintain the conveyor belt 104, whose upper side is flush with the table surface of the workbench 101.
[0032] In this embodiment: the glue spraying assembly 2 includes a horizontal linear guide rail 201 fixedly installed at the front and rear of the workbench 101, a horizontal sliding table 202 movably installed on the horizontal linear guide rail 201, a vertical linear guide rail 203 fixedly installed between the two horizontal sliding tables 202, a vertical sliding table 204 movably installed on the vertical linear guide rail 203, a carrier 205 fixedly installed on the vertical sliding table 204, a glue storage tank 206 fixedly installed inside the carrier 205, a pump 207 fixedly installed on one side of the carrier 205 with its feed end fixedly connected to the discharge end of the glue storage tank 206, a glue spraying cylinder 208 fixedly installed on the other side of the carrier 205, a glue spraying head 209 fixedly connected to the telescopic end of the glue spraying cylinder 208, and a connecting pipe 210 fixedly connected between the discharge end of the pump 207 and the feed end of the glue spraying head 209;
[0033] The longitudinal linear guide 203 is installed via a transverse slide 202 that can be precisely moved along the length of the transverse linear guide 201. The carrier 205 is installed via a longitudinal slide 204 that can be precisely moved along the length of the longitudinal linear guide 203. The cooperation and usage of the linear guide and slide are known prior art to those skilled in the art, and will not be described in detail here. The carrier 205 provides installation positions for the glue storage tank 206, the pump 207, and the glue spraying cylinder 208, so that the glue spraying head 209, whose height can be adjusted by the glue spraying cylinder 208, can move horizontally with the carrier 205 due to the position changes of the transverse slide 202 and the longitudinal slide 204. The glue spraying head 209 sprays outward the adhesive injected into the connecting pipe 210, which is pumped out quantitatively from the glue storage tank 206 by the pump 207.
[0034] In this embodiment: the positioning component 3 includes a clamping component that can make multi-point contact with the paper packaging box conveyed to the glue spraying station to fully limit its position, a control component that can switch the horizontal position of the blocking block 301 according to the specifications of the paper packaging box and the needs of conveying and glue spraying, and an adjusting component that can adjust the clamping force of the longitudinal moving block 305 on the paper packaging box.
[0035] The clamping components include two longitudinally aligned blocking blocks 301 positioned on the workbench 101. A support rod 302 is fixedly connected above each blocking block 301. A bending block 303 is located on one side of each blocking block 301. A multi-stage telescopic rod 304 is fixedly connected to one side of the bending block 303. A longitudinal movement block 305 is fixedly connected between the two multi-stage telescopic rods 304. The control components include a limiting sub-frame 306 fixedly mounted on the workbench 101. A limiting main frame 307 is fixedly connected to the side of the limiting sub-frame 306 closest to the longitudinal movement block 305. A space is provided between the limiting sub-frame 306 and the limiting main frame 307, corresponding to the position of the blocking block 301. 01. A sliding rod 308 is movably connected. A positioning cylinder 309 is provided on one side of the sliding rod 308 between the blocking block 301 and the limiting main frame 307. A connecting handle 310 is provided on the other side of the sliding rod 308 between the blocking block 301 and the limiting main frame 307. The adjusting component includes two limiting rods 311 fixedly connected to the side of the longitudinal moving block 305 near the limiting sub-frame 306. A thrust bracket 312 is movably connected between the two limiting rods 311. A screw 313 is movably connected to the front of the thrust bracket 312. A spring 314 is provided between the longitudinal moving block 305 and the thrust bracket 312 and is movably connected to the limiting rod 311.
[0036] The blocking block 301 and the support rod 302 are slidably connected to the bending block 303. The blocking block 301, the limiting sub-frame 306, and the limiting main frame 307 are slidably connected to the sliding rod 308. The positioning cylinder 309 and the connecting handle 310 are rotatably connected to the blocking block 301 and the limiting main frame 307. The limiting sub-frame 306, the limiting main frame 307, the thrust frame 312, and the spring 314 are slidably connected to the limiting rod 311. The limiting sub-frame 306 and the limiting main frame 307 are threadedly connected to the screw 313. The thrust frame 312 is rotatably connected to the screw 313.
[0037] The movable range is limited by the limiting subframe 306 and the limiting mainframe 307, both of which are connected to the blocking blocks 301. The blocking blocks 301, which are in contact with both sides of the paper packaging box, can move horizontally on the workbench 101 due to the operation of the positioning cylinder 309. Simultaneously, the length direction of the moving blocking blocks 301 is always perpendicular to the length direction of the conveyor belt 104. The movable range is further limited by the limiting rod 311 via the support rod 302, bending block 303, and multi-stage telescopic rod 304. The longitudinal moving block 305, which is limited by the spring 314 and used to contact the front or rear side of the paper packaging box, can move longitudinally with the horizontal movement of the blocking block 301, and can also move longitudinally relative to the blocking block 301 under the action of external force. By rotating the screw 313 relative to the limiting sub-frame 306 and the limiting main frame 307, the longitudinal position of the thrust bracket 312 on the limiting rod 311 is adjusted, that is, the distance between the longitudinal moving block 305 and the thrust bracket 312 is changed. By the longitudinal movement of the thrust bracket 312, which is in contact with the spring 314 on one side, the elastic force applied by the spring 314 to the longitudinal moving block 305 is adjusted.
[0038] Working principle: When this glue spraying machine is installed for the production of paper packaging boxes, it can continuously spray glue onto the paper packaging boxes according to the position of the glue spraying area of the paper packaging box at the glue spraying station. After presetting the operation mode of the transverse slide 202, longitudinal slide 204, pump 207, glue spraying cylinder 208, positioning cylinder 309, and the position of the thrust bracket 312, the machine can continuously spray glue onto the paper packaging boxes.
[0039] Specifically, after the above settings are completed, when the paper packaging box to be sprayed with glue is placed on one side of the workbench 101 in a preset manner on the conveyor belt 104 that rotates due to the operation of the motor 105, the conveyor belt 104 will drive the paper packaging box to move laterally towards the two sets of positioning components 3. When the paper packaging box moves laterally and passes the blocking block 301 closest to its placement position, each positioning cylinder 309 can work synchronously to push the connected blocking block 301 to move horizontally. Since the blocking block 301 is limited by the sliding rod 308, the positioning cylinder 309, and the connecting handle 310, it will move longitudinally towards the blocking block 301 in the other positioning component 3 at the same lateral position during the process of moving laterally towards the longitudinal block 305. After each blocking block 301 has moved horizontally, the paper packaging box can be stopped and clamped. On both sides, two longitudinal blocks 305, which move in opposite directions due to springs 314, will stop moving when they come into contact with the front and rear sides of the paper packaging box as they move longitudinally with the blocking block 301. When the positioning cylinders 309 operate synchronously and the spring force applied by each spring 314 to the corresponding longitudinal block 305 is the same, the blocking blocks 301 and longitudinal blocks 305 after contacting the paper packaging box will accurately position the paper packaging box at the glue spraying station below the glue spraying head 209. After the paper packaging box is in place, the transverse slide 202 and the longitudinal slide 204 can move the glue spraying head 209 to the target area in a preset manner. During this period, the pump 207 and the glue spraying cylinder 208 can work together to make the glue spraying head 209 spray the adhesive evenly onto the target area of the paper packaging box.
[0040] After the glue spraying is completed, the positioning cylinder 309 is reset synchronously when the glue spraying head 209 is reset, so that the paper packaging box no longer contacts the blocking block 301 and the longitudinal moving block 305, and is conveyed out of the glue spraying machine by the conveyor belt 104 for subsequent processing.
[0041] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
