Description

Technical Field

[0001] The invention relates to the technical field of carton production positioning, and in particular to a non-stop shaping structure of a carton nailing machine. Background Art

[0002] The carton stitching machine is an automated device used in carton production. Its main function is to stitch folded carton blanks (unassembled cartons, such as Fig.10 The carton stapler is widely used in the packaging industry, especially in large-scale carton production. It is usually composed of the following main parts: Carton blank feeding system: the carton blank is fed into the working area by a conveyor belt; Carton positioning system: the carton is accurately positioned to ensure its correct angle and position during the stapling process; Stapling system: the folded part of the carton is fixed by a nail pin or a nail gun to ensure the stability of the carton; Discharging system: the carton is sent out after stapling; The correct positioning of the carton before it is fed into the stapling system is one of the key steps, because the carton blank will be offset during the transportation process. In order to ensure the accuracy of stapling, the angle and position of the carton must be adjusted.

[0003] However, the existing correction process usually requires the carton to stop during correction, which means that during the process of adjusting the carton, the conveyor belt will stop and the carton will be adjusted in a static state, which restricts the continuity of the nailing process. Since each carton needs to stop during correction, the entire production process becomes less smooth and inconvenient for continuous molding production of carton blanks. Summary of the invention

[0004] The present invention provides a non-stop shaping structure for a carton nailing machine, which solves the technical problem that the correction process of the existing carton nailing machine requires the carton to pause during adjustment, causing the conveyor belt to stop running and the carton to be in a static state.

The lower end surfaces of the two cross beams 414 are fixedly connected to the guide rails 415, and the lower parts of the two guide rails 415 are slidably connected to the sliding plate 411. The left bearing plate 413 and the right bearing plate 412 are rotatably connected together. The upper end surface of the slide plate is fixedly connected to the nut seat 417 threadedly connected to the screw 416, and the left bearing plate 413 is provided with a driving component 418 drivingly connected to the screw 416.

[0037] Before stapling the carton blank, place the external conveying device at the position between the lower L-shaped material guide plate 32 and the centering mechanism 5, and then control the distance adjustment component 41 to operate and adjust the distance between the laterally corresponding L-shaped plates 425 in the two push and push units 42 according to the specific length of the carton blank: control the driving member 418 to operate and drive the thread to rotate, the screw rod 416 then drives the nut seat 417 to move, the nut seat 417 then drives the sliding plate 411 to move, and the sliding plate 411 then drives the push and push unit 42 located on the left to move, so that the distance between the two push and push units 42 can be adjusted; then control the external conveying device to operate and drive the carton blank to move to the left, so that the carton blank enters between the four L-shaped material guide plates 32 distributed in a matrix shape, and at this time the strip pressure plate 33 contacts the upper surface of the carton blank to prevent the un-stitched carton board on the upper part of the carton blank from tilting upward.

[0038] When the carton blank moves to the left to the position directly below the two push and push units 42, the driving member 426 in the right push and push unit 42 is first controlled to operate, and the driving member 426 then drives the rotating shaft 422 to rotate, and the rotating shaft 422 then drives the sprocket 423 to rotate, and the sprocket 423 then drives the L-shaped plate 425 to rotate through the chain 424, and the L-shaped plate 425 rotates and abuts against the right side of the carton blank, and the L-shaped plate 425 pushes the carton blank further to the left, and the carton blank that has been pushed to the left abuts against the L-shaped plate 425 located in the left push and push unit 42, which is now at the bottom, and the movement speed of the chain 424 on the left is slightly lower than that of the chain 424 on the right, and the two L-shaped plates 425 in the horizontal direction jointly push from the left and right sides of the carton blank, so that the carton blank can be aligned and corrected.

[0039] The corrected carton blank is then driven by the conveying device to move to the left and completely removed from under the push and push units 42. When the next carton blank moves to the position under the two push and push units 42, the front L-shaped plate 425 located at the upper part is driven by the chain 424 to move to the lower position, and then the above-mentioned steps of the L-shaped plate 425 in the right push and push unit 42 abutting against the right part of the carton blank and subsequent steps are repeated, so that the carton blank moved to under the two push and push units 42 can be positioned and corrected, and the carton blank can be continuously positioned and corrected by the corresponding L-shaped plates 425 in the two push and push units 42 cooperating with each other.

[0040] After the conveying device drives the adjusted carton blank to move to the left for a distance, the carton blank will touch the arc-shaped plate segment of the folding limit plate 9, and then the arc surface of the arc-shaped plate segment of the folding limit plate 9 slightly squeezes the carton blank toward the middle and moves it, and then the carton blank moves to the straight section position in the folding limit plate 9, thereby limiting the adjusted carton blank to prevent it from shifting.

[0041] See also Figure 2 , Figure 4 and Figure 5In this embodiment, the centering mechanism 5 includes a sliding table 51, a slide groove 52, a mounting strip 53, a push-pushing assembly 54, a rotating shaft 55, a waist-shaped disk 56, a pull rod 57 and a linkage unit 58.

[0045] The operation of the push-pushing unit 42 will not only adjust and correct the carton blank to the left and right, but also drive the centering mechanism 5 to operate: when the L-shaped push plate 425 at the front side of the push-pushing unit 42 located on the right moves to the upper part along with the chain 424, it will touch the receiving post 5810 and push the receiving post 5810 to move right synchronously, and the receiving post 5810 will then drive the slider 589 to move right, and the slider 589 will then drive the wedge block 5811 to move right, and during the rightward movement of the wedge block 5811, its inclined surface will squeeze the top post 5812 to move forward, and the top post 5812 will then drive the strip push plate 588 to move forward outside the guide post 586, and the strip push plate 588 will then push the strip slide 587 forward The strip slide 587 then drives the rack 584 forward through the slide bar 582, and the rack 584 then drives the gear ring 583 to rotate, and the gear ring 583 then drives the waist-shaped plate 56 to rotate through the rotating shaft 55, and the waist-shaped plate 56 then pulls the front and rear mounting strips 53 to move closer to each other through the pull rod 57, and the mounting strips 53 then drive the T-shaped plate to move closer to the middle, and the two T-shaped plates 541 then drive the front and rear relative elastic rollers 543 to move closer to each other through the spring telescopic column and the C-shaped frame 542, and the elastic rollers 543 move after moving. After the elastic rollers 543 are moved, they come into contact with the front and rear sides of the carton blank that has been adjusted and corrected left and right, and then the carton blank can be adjusted and corrected from the front and rear directions.

[0046] When the elastic roller 543 has finished adjusting the carton blank forward and backward, the chain 424 drives the L-shaped plate 425 to start moving from the upper part to the lower part, and the L-shaped plate 425 moves to separate from the receiving column 5810, and the return spring pushes the slider 589 to move to the left and reset, and the slider 589 then drives the wedge block 5811 left and right, and the inclined surface of the wedge block 5811 gradually moves away from the top column 5812, and stops pressing the top column 5812, and then the top spring pushes the strip push plate 588 to move backward and reset, and the strip push plate 588 then drives the rack 584 forward through the strip slide 587 and the slide rod 582, and the rack 584 then drives the gear ring 583 to reverse , the gear ring 583 then drives the waist-shaped plate 56 to reverse through the rotating shaft 55, and the waist-shaped plate 56 then pushes the mounting strip 53 to move through the pull rod 57, and the two mounting strips 53 are moved away from each other under the reset push of the reset spring, and the mounting strip 53 then drives the T-shaped plate 541, the C-shaped frame 542 and the elastic roller 543 to move synchronously until they move to the initial position; when the next carton blank moves to the position directly below the two push units 42, the push units 42 start to run again to adjust and correct the carton blank left and right, which will trigger the centering mechanism 5 to run, and the centering mechanism 5 will adjust the carton blank in the center from the front and back directions.

[0047] See also Figure 6 In this embodiment, the self-centering mechanism 6 includes a transverse frame 61 fixedly connected to the rear end surface of the support plate 421, a connecting rod 62 hinged to the rear end surface of the transverse frame 61, a sliding rod 63 fixedly connected to the rear part of the upper end surface of the sliding platform 51, and a sliding sleeve 64 slidably connected to the outside of the sliding rod 63, and the lower ends of the two connecting rods 62 are hinged to the outside of the sliding sleeve 64.

[0048] When the distance adjustment component 41 drives the left support plate 421 to adjust its position, the left support plate 421 will drive the horizontal frame 61 on the left to move, and the horizontal frame 61 on the left will then drive the connecting rod 62 to move. The left connecting rod 62 will then drive the sliding sleeve 64 to move up and left at the same time. The sliding sleeve 64 then drives the right connecting rod 62 and the left connecting rod 62 to move in a mirrored manner. The sliding sleeve 64 moves left and drives the sliding table 51 to move synchronously. The sliding table 51 moves left and also indirectly drives the strip slide 587 to move left. The two connecting rods 62 move in a mirrored manner, so that the sliding sleeve 64 moves left as the left support plate 421 moves left, thereby ensuring that the sliding table 51 is always located between the two support plates 421, thereby ensuring that the centering mechanism 5 can always be located in the middle of the carton blank when correcting the top contact of the carton blank.

[0049] During operation, the external conveying device is first moved between the material guiding part 3 and the centering mechanism 5, and then the distance between the two pushing and pushing units 42 is adjusted through the distance adjusting component 41 in the alignment mechanism 4 according to the length of the carton blank. When the distance between the pushing and pushing units 42 is adjusted, the self-centering mechanism 6 will be triggered to run, and the self-centering mechanism 6 will then drive the centering mechanism 5 to move, so that the centering mechanism 5 is located between the two pushing and pushing units 42. Then the external conveying device is controlled to run to drive the carton blank to move through the material guiding part 3. When the carton blank is driven to move to the position directly below the pushing and pushing units 42 in the alignment mechanism 4, the alignment mechanism 4 will run to adjust and correct the carton blank from the left and right directions.
