Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, and in particular to a paperboard edge-wrapping feeding mechanism. Background Technology

[0002] Paper boxes are a common packaging material for products and a widely used green packaging container. They are widely used not only for packaging pharmaceuticals, food, cigarettes, and handicrafts, but also for soft drinks, detergents, stationery, and small hardware products. They have advantages such as low processing costs and convenient storage and transportation.

[0003] When paper is formed, it usually needs to be edged. This is done by wrapping the edges of the cardboard with a piece of paper that is larger than the cardboard. Before wrapping, glue is applied to the bottom of the cardboard. Then the paper is glued to the cardboard. After the paper is glued, the excess part of the paper is bent inward to surround the edge of the cardboard, thus achieving edge wrapping.

[0004] Before edge binding, the cardboard with the paper pieces attached needs to be loaded onto the edge binding station. Most existing loading mechanisms directly transfer the cardboard to the edge binding station via the suction tray of the suction rack. This solution lacks positioning, which can easily cause the cardboard to mismatch with the station, resulting in collisions between the cardboard and the station and causing the cardboard to bend. Utility Model Content

[0005] The purpose of this utility model is to provide a cardboard edge-wrapping feeding mechanism to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A cardboard edge-sealing feeding mechanism includes a bottom conveyor for forward conveying cardboard with paper sheets attached, and a transfer mechanism for transferring the cardboard from the bottom conveyor to the next process. The bottom conveyor is provided with a correction and positioning mechanism for correcting the cardboard. The correction and positioning mechanism includes a pair of side positioning strips and a side positioning block disposed between the two side positioning strips. The two side positioning strips move in the width direction of the bottom conveyor to clamp and position the cardboard, and the side positioning block can move along the length direction of the bottom conveyor. There is a gap between the side positioning strips and the bottom conveyor, and the side positioning strips can abut against the side edge of the cardboard when they move.

[0008] Furthermore, the correction and positioning mechanism also includes a transverse side plate, which is provided with a first moving point and a second moving point. The first moving point and the second moving point are close to or far from each other, allowing the two side positioning bars to move simultaneously. The first moving point is connected to one of the side positioning bars, and the second moving point is connected to the other side positioning bar.

[0009] Furthermore: a belt conveyor is installed on the transverse side plate, the belt conveyor including a drive belt, the first moving point being located on one of the long sides of the drive belt, and the second moving point being located on the other long side of the drive belt.

[0010] Furthermore, the belt conveyor also includes synchronous pulleys installed at both ends of the transverse side plate, with the drive belt sleeved between the two synchronous pulleys.

[0011] Furthermore: a transverse guide rail is arranged along the length of the transverse side plate, and a pair of positioning strip sliding seats are slidably installed on the transverse guide rail, with the bottom of the positioning strip sliding seats connected to the side positioning strip.

[0012] Furthermore: transmission seats are installed on the two long sides of the transmission belt, and the transmission seats are connected to the corresponding positioning strip sliding seats.

[0013] Furthermore: there are two transverse side plates and two belt conveyors. A drive shaft is installed between the two transverse side plates. The drive shaft is installed between two coaxially aligned synchronous pulleys. One of the transverse side plates is equipped with a drive motor. The drive end of the drive motor is connected to the drive shaft.

[0014] Furthermore: one of the transverse side plates is provided with a stop moving mechanism that drives the side positioning stop to move. The stop moving mechanism includes a stop mounting base, and a stop linear guide rail is installed at the bottom of the stop mounting base. The side positioning stop can move along the length direction of the stop linear guide rail. The stop mounting base is provided with a telescopic drive member arranged along the length direction of the stop linear guide rail. The drive end of the telescopic drive member is connected to the side positioning stop.

[0015] Furthermore, the transfer mechanism includes an adsorption rack capable of vertical movement, which can move along the width of the bottom conveyor, and the adsorption rack is equipped with multiple adsorption trays that contact the cardboard.

[0016] Furthermore: a transfer guide rail is provided along the length of the transverse side plate, and a transfer drive plate is provided between the two transverse side plates. A transfer sliding seat that slides with the transfer guide rail is installed at both ends of the transfer drive plate; a lifting drive component is installed on the transfer drive plate, and the drive end of the lifting drive component is connected to the adsorption frame.

[0017] The beneficial effects of this invention are as follows: The cardboard with the paper sheet attached enters the correction and positioning mechanism via the bottom conveyor. Side positioning blocks hold the cardboard in place, preventing it from moving forward. Subsequently, a pair of side positioning strips move closer together, dynamically clamping the two edges of the cardboard. This simultaneous clamping on both sides eliminates lateral offset of the cardboard, ensuring the cardboard's centerline is aligned with the edge-sealing station. Because the paper sheet is adhesive, the gap between the side positioning strips and the bottom conveyor allows the strips to contact only the sides of the cardboard during movement, preventing the paper sheet from sticking to the strips and ensuring positioning stability. The transfer mechanism then picks up the positioned cardboard and transfers it to the next process, the edge-sealing station. Attached Figure Description

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] like Figure 1-3As shown, a cardboard edge-wrapping feeding mechanism includes a bottom conveyor 35 for forward conveying of cardboard with paper sheets attached, and a transfer mechanism 1 for transferring the cardboard from the bottom conveyor 35 to the next process. The bottom conveyor 35 is provided with a correction and positioning mechanism 2 for correcting the cardboard. The correction and positioning mechanism 2 includes a pair of side positioning strips 28 and a side positioning block 34 disposed between the two side positioning strips 28. The two side positioning strips 28 move in the width direction of the bottom conveyor 35 to clamp and position the cardboard. The side positioning block 34 can move along the length direction of the bottom conveyor 35. There is a gap between the side positioning strips 28 and the bottom conveyor 35. The side positioning strips 28 can abut against the side of the cardboard when moving.

[0033] The cardboard with the paper attached is conveyed into the alignment and positioning mechanism 2 by the bottom conveyor 35. The side positioning blocks 34 hold the cardboard in place, preventing it from moving further. Then, a pair of side positioning strips 28 move closer together, dynamically clamping the edges of the cardboard. This simultaneous clamping on both sides eliminates lateral offset of the cardboard, ensuring the cardboard's centerline is aligned with the edge-sealing station. Because the paper is adhesive, the gap between the side positioning strips 28 and the bottom conveyor 35 allows the side positioning strips 28 to only contact the sides of the cardboard during movement, preventing the paper from sticking to the side positioning strips 28 and ensuring positioning stability. Subsequently, the transfer mechanism 1 picks up the positioned cardboard and transfers it to the edge-sealing station in the next process.

[0034] Furthermore, the correction and positioning mechanism 2 also includes a transverse side plate 10, which is provided with a first moving point and a second moving point. The first moving point and the second moving point are close to or far from each other, allowing the two side positioning strips 28 to move simultaneously. The first moving point is connected to one of the side positioning strips 28, and the second moving point is connected to the other side positioning strip 28. The dual-point drive structure of the transverse side plate 10 ensures that the two side positioning strips 28 maintain strict displacement synchronization during movement; the dual-point drive distributes the driving force to the two moving points, reducing the torque concentration problem of single-point drive; the synchronous movement of the two side positioning strips 28 reduces the path of paper movement during positioning.

[0035] Preferably, the lead screw can be driven by a servo motor, and the first and second moving points can move towards or away from each other at the same speed, so that the error in the spacing of the positioning bars 28 on both sides is controlled within an effective range.

[0036] Preferably, the transverse side plate 10 is equipped with a belt conveyor, which includes a transmission belt 21. The first moving point is located on one of the long sides of the transmission belt 21, and the second moving point is located on the other long side of the transmission belt 21. When the transmission belt 21 moves, the two long sides move respectively, so that the first moving point and the second moving point move towards or away from each other at the same speed, achieving synchronous movement, which has the same technical effect as a servo motor driving a lead screw.

[0037] Furthermore, the belt conveyor also includes synchronous pulleys 22 installed at both ends of the transverse side plate 10, and the transmission belt 21 is sleeved between the two synchronous pulleys 22, so that the transmission belt 21 is arranged in a racetrack shape, and the two synchronous pulleys 22 drive the transmission belt 21 to move.

[0038] Preferably, there are two transverse side plates 10 and two belt conveyors. A drive shaft 23 is installed between the two transverse side plates 10. The drive shaft 23 is installed between two coaxially aligned synchronous pulleys 22. One of the transverse side plates 10 is equipped with a drive motor 24. The drive end of the drive motor 24 is connected to the drive shaft 23. The two transverse side plates 10 move synchronously through the drive shaft 23 and the synchronous pulleys 22. The synchronous movement of the belt conveyors of the two transverse side plates 10 can drive the two side positioning strips 28 to move closer or further away synchronously, thereby achieving the clamping and positioning of the cardboard.

[0039] Furthermore, the transverse side plate 10 is provided with transverse guide rails 25 along its length. A pair of positioning strip sliding seats 26 are slidably mounted on the transverse guide rails 25, and the bottom of the positioning strip sliding seats 26 is connected to the side positioning strips 28. Transmission seats 27 are respectively mounted on the two long sides of the transmission belt 21, and the transmission seats 27 are connected to the corresponding positioning strip sliding seats 26. The cooperation between the transverse guide rails 25 and the positioning strip sliding seats 26 forms a double-guide structure, which can effectively resist the lateral force generated by the positioning strips when clamping the cardboard.

[0040] Furthermore, the transverse guide rail 25 and the positioning strip sliding seat 26 are detachably connected, such as by bolts. When the sliding seat or rail needs to be replaced due to wear, it can be disassembled and installed within 15 minutes without disassembling the entire positioning mechanism 2.

[0041] One of the transverse side plates 10 is equipped with a stop-moving mechanism 3 that moves the side positioning stop 34. The stop-moving mechanism 3 includes a stop mounting base 31, with a stop linear guide rail 32 mounted on the bottom of the stop mounting base 31. The side positioning stop 34 can move along the length direction of the stop linear guide rail 32. The stop mounting base 31 is equipped with a telescopic drive member 33 arranged along the length direction of the stop linear guide rail 32, and the drive end of the telescopic drive member 33 is connected to the side positioning stop 34. The position of the side positioning stop 34 can be adjusted according to the size of the cardboard by moving the side positioning stop 34 along the length direction of the stop linear guide rail 32 via the telescopic drive member 33, thereby achieving position adjustment.

[0042] It should be noted that there is a gap between the side positioning block 34 and the bottom conveyor 35, which is the same principle as the side positioning strip 28. Since the paper is sticky, the gap between the side positioning block 34 and the bottom conveyor 35 allows the side positioning block 34 to only contact the side of the cardboard when moving, without contacting the paper, thus preventing the paper from sticking to the side positioning block 34 and ensuring the stability of the positioning.

[0043] Preferably, the telescopic drive component 33 is a telescopic cylinder, but it can also be an electric push rod.

[0044] The transfer mechanism 1 includes a lifting and lowering suction frame 14, which can move along the width direction of the bottom conveyor 35. The suction frame 14 is equipped with multiple suction trays 17 that contact the cardboard. Multiple transverse mounting strips 15 are installed at the bottom of the suction frame 14. The transverse mounting strips 15 are formed with adjusting grooves 16 along their length direction. The top of the suction trays 17 are slidably mounted on the adjusting grooves 16. The position of the suction trays 17 can be adjusted according to the size of the cardboard to match the cardboard, which is convenient for the suction and transfer of cardboard of different sizes.

[0045] Furthermore, the transverse side plates 10 are provided with transfer guide rails 11 along their length, and a transfer drive plate 12 is provided between the two transverse side plates 10. Transfer sliding seats 13, which slide and cooperate with the transfer guide rails 11, are respectively installed at both ends of the transfer drive plate 12. A transverse drive member 18 is arranged along the length of the transverse side plates 10, which can drive the transfer sliding seats 13 to move along the length of the transfer guide rails 11, thereby transferring the cardboard. A lifting drive member 19 is installed on the transfer drive plate 12, and the drive end of the lifting drive member 19 is connected to the suction frame 14. The lifting drive member 19 can drive the suction frame 14 to lift or lower the cardboard.

[0046] Preferably, the transverse drive member 18 is a belt conveyor arranged along the length of the transverse side plate 10. A drive seat is installed on one of the long sides of the belt conveyor. The drive seat is connected to the transfer sliding seat 13, thereby realizing the movement of the transfer drive plate 12 and driving the adsorption frame 14 to move between the edge-sealing station and the bottom conveyor 35.

[0047] Preferably, the transverse drive component 18 is a linear module arranged along the length of the transverse side plate 10. The drive end of the linear module is connected to the transfer sliding seat 13, thereby realizing the movement of the transfer drive plate 12 and driving the adsorption frame 14 to move between the edge-sealing station and the bottom conveyor 35.

[0048] Preferably, the lifting drive 19 can be a longitudinally arranged screw transmission mechanism to realize the lifting movement of the adsorption frame 14.

[0049] Preferably, the bottom conveyor 35 is a conveyor belt.

[0050] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
