Description

Technical Field

[0001] This utility model belongs to the technical field of packaging production line equipment, and specifically relates to a packaging box conveying device with a correction function. Background Technology

[0002] Modern packaging production lines commonly use conveyor belts as the material transport carrier to replace manual labor and achieve fast, accurate, and efficient material transfer. However, existing conveyor lines are generally simple rotating strip structures. During the transport process, materials are piled up haphazardly, disorderly, and inconsistently oriented on the conveyor belt, which seriously affects subsequent packaging processing, such as sealing or marking / coding of boxes. Furthermore, manual sorting and alignment are often required, reducing the efficiency of box transport and subsequent packaging. At the same time, existing conveyor belts usually do not have side barriers, which often leads to disordered arrangement of tall or narrow boxes, such as solid granule or powder boxes, and boxes tilting, falling, or even detaching during transport, severely impacting the efficiency of subsequent packaging processing. In addition, although some conveyor lines have barriers on both sides, the barriers on both sides of existing conveyor lines are generally fixed and cannot be adjusted according to needs (such as packaging boxes of different sizes). They can only prevent the conveyed materials from falling off, but cannot guarantee the neat arrangement of the packaging box materials. Furthermore, they cannot effectively prevent the tilting and tipping of some packaging boxes with larger dimensions during the conveying process.

[0003] Therefore, it is necessary to design a packaging box conveying device with a correction function that can at least solve some of the above problems and defects. Summary of the Invention

[0004] To solve the above technical problems, this utility model proposes a packaging box conveying device with a correction function. It can adjust and straighten the packaging box materials being transported, ensuring that the packaging boxes are arranged neatly and uniformly, avoiding the impact of scattered packaging boxes on subsequent packaging processing, and reducing the risk of packaging boxes tilting, falling, or even detaching during the conveying process. This improves the stability and reliability of the conveying process. In addition, it is applicable to packaging box materials of different specifications and sizes, and has strong practicality and wide applicability.

[0005] The technical solution of this utility model is:

[0006] This utility model proposes a packaging box conveying device with a correction function, including a support frame with a conveyor belt, two side baffles symmetrically mounted on the left and right sides above the support frame, and at least one set of height adjustment unit, width adjustment unit and correction unit symmetrically mounted on the left and right sides of the support frame.

[0007] The height adjustment unit is fixedly mounted on the side wall of the support frame. The width adjustment unit is connected to the height adjustment unit and is mounted above the height adjustment unit. The side baffle is connected to the width adjustment unit and is mounted inside the width adjustment unit, allowing it to move laterally left and right. The correction unit is fixedly mounted on the side wall of the support frame and is equipped with a rotatable swing wheel positioned between the side baffle and the conveyor belt. The rotation center axis of the swing wheel is perpendicular to the plane of the conveyor belt and is located outside the side baffle. The distance between the rotation center axis of the swing wheel and the inner side wall of the side baffle is less than the radius of the swing wheel.

[0008] Preferably, the correction unit includes a fixed seat fixedly disposed on the side wall of the support frame, at least one guide rod vertically fixedly disposed on the fixed seat, and a guide seat sleeved on the outer periphery of the guide rod that can move laterally left and right.

[0009] The swivel wheel is rotatably and vertically mounted on the guide seat.

[0010] Preferably, the correction unit further includes an adjusting screw that is rotatably and vertically disposed on the fixed base, and a limiting seat that is fixedly disposed at the end of the guide rod;

[0011] The guide rods are provided in two parallel configurations. The adjusting screw is parallel to the guide rods and located between the two guide rods. The adjusting screw movably passes through the limiting seat and has an adjusting knob at its end. The guide seat movably passes through the guide rods and the adjusting screw and is threadedly connected to the adjusting screw.

[0012] Preferably, the correction unit further includes a swivel motor fixedly mounted on the guide seat, and the swivel wheel is fixedly mounted at the end of the output shaft of the swivel motor.

[0013] Preferably, the height adjustment unit includes a mounting base fixedly disposed on the side wall of the support frame, a base fixedly disposed vertically on the mounting base, a longitudinal rod vertically and movably passing through the base, and a first locking knob movably disposed on the base.

[0014] The top end of the longitudinal rod is fixedly connected to the width adjustment unit, and the first locking knob extends into the base and abuts against the longitudinal rod perpendicularly.

[0015] Preferably, the width adjustment unit includes a positioning block fixedly disposed at the top end of the longitudinal rod, a transverse rod horizontally and movably passing through the positioning block, and a second locking knob movably disposed on the positioning block;

[0016] The inner end of the transverse rod is connected to the side baffle, and the second locking knob extends into the positioning block and abuts perpendicularly against the transverse rod.

[0017] Preferably, the side baffle includes an inner layer plate located on the inner side and a support plate fixedly embedded on the outer side of the inner layer plate. The inner layer plate is provided with a receiving groove arranged along its length direction, and the support plate is fixedly embedded in the receiving groove.

[0018] Preferably, the inner end of the transverse rod is provided with a slider that is fixedly connected thereto, and the outer wall of the support plate is provided with a transverse groove arranged along its length direction, and the slider is reciprocally disposed in the transverse groove.

[0019] Preferably, the support frame includes a main frame body with a conveyor belt and a base rod fixedly installed at the bottom of the main frame body. The base rods are arranged in a plurality of positions and are spaced apart along the length of the main frame body.

[0020] The base rod is an inverted "Y" shaped rod, and an adjustment seat with a threaded connection is provided at its bottom.

[0021] This utility model has the following advantages and effects compared with the prior art:

[0022] (1) A correction unit with a swing wheel is adopted. The swing wheel is set in the gap between the top of the conveyor belt and the bottom of the side baffle. The distance between the rotation center axis of the swing wheel and the inner side wall of the side baffle is smaller than the radius of the swing wheel, so that the outer edge of the swing wheel extends inward and contacts the packaging box material transported by the conveyor belt, thereby correcting the swing of the packaging box and improving the regularity and consistency of the packaging box conveying arrangement, which is convenient for subsequent packaging processing.

[0023] (2) A guide seat that can move horizontally left and right is adopted and the swing wheel is fixedly set on the guide seat. The position of the guide seat can be adjusted by moving horizontally left and right to change the distance between the outer edges of the swing wheels on the left and right sides, thereby adapting to packaging box materials of different specifications and sizes, improving practicality and expanding the scope of application.

[0024] (3) A toggle motor is fixedly mounted on the guide seat and the toggle wheel is fixedly mounted at the end of the output shaft of the toggle motor. The toggle motor drives the toggle wheel to rotate actively, so as to assist in pushing the packaging box material through the toggle wheel, avoid the packaging box from accumulating and blocking at the toggle wheel position, and improve the stability of the packaging box material when passing through the toggle wheel, and reduce the risk of tipping over.

[0025] (4) A height adjustment unit is fixedly installed on the side wall of the support frame to adjust the height of the side baffle, thereby adapting to packaging boxes of different height specifications. For example, for some packaging boxes with larger height, the height of the side baffle can be adjusted to be flush with the upper part of the middle of the packaging box, so as to play a stable limiting role for the packaging box material, thereby avoiding the phenomenon of tilting, falling or even detaching and falling.

Detailed Implementation

[0032] To enable those skilled in the art to better understand this utility model, it will now be further described in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this utility model.

[0033] Example:

[0034] like Figures 1-5As shown, this utility model provides a packaging box conveying device with a correction function, which includes a support frame 1 with a conveyor belt, two side baffles 2 symmetrically mounted on the left and right sides above the support frame 1, and at least one set of height adjustment unit 3, width adjustment unit 4, and correction unit 5 symmetrically mounted on the left and right sides of the support frame 1. The side baffles 2 are arranged along the length direction of the support frame 1 (i.e., the conveying direction of the packaging boxes on the conveyor belt) and are mounted directly above the conveyor belt to limit the packaging boxes transported by the conveyor belt and prevent them from being arranged in a disorderly manner, tilting, falling over, or even detaching and falling off.

[0035] Combination Figure 1 and Figure 2 As shown, at least one set of height adjustment unit 3, width adjustment unit 4, and correction unit 5 are provided on both the left and right sides of the support frame 1. Specifically, in this embodiment, two sets of width adjustment units 4 and height adjustment units 3 are provided on both the left and right sides of the support frame 1, and one set of correction unit 5 is provided on both the left and right sides of the support frame 1, with the correction unit 5 located between the two sets of height adjustment units 3. In actual product applications, the number and position of the height adjustment unit 3, width adjustment unit 4, and correction unit 5 can be set as needed according to the specifications and dimensions of the support frame 1 and the side baffle 2, which will not be elaborated further here. The height adjustment unit 3 is fixedly installed on the side wall of the support frame 1. The width adjustment unit 4 is connected to the height adjustment unit 3 and is installed above the height adjustment unit 3. The side baffle 2 is connected to the width adjustment unit 4 and is installed inside the width adjustment unit 4, which can move laterally left and right. The correction unit 5 is fixedly installed on the side wall of the support frame 1 and is equipped with a rotatable swing wheel 51 arranged between the side baffle 2 and the conveyor belt. The rotation center axis of the swing wheel 51 is perpendicular to the plane of the conveyor belt and is located outside the side baffle 2. The distance between the rotation center axis of the swing wheel 51 and the inner side wall of the side baffle 2 is less than the radius of the swing wheel 51, so that the rim of the swing wheel 51 extends inward a certain distance relative to the inner side wall of the side baffle 2. That is, the swing wheel 51 is rotatably installed in the gap between the side baffle 2 and the conveyor belt. It should be noted that in this embodiment, the height of the left and right side walls of the support frame 1 is not greater than the height of the upper surface of the conveyor belt. When the height of the left and right side walls of the support frame 1 is greater than the height of the upper surface of the conveyor belt, the lower end face of the swing wheel 51 needs to be set above the side walls of the support frame 1 to ensure the normal rotation of the swing wheel 51. In addition, the swing wheel 51 is preferably made of plastic or rubber material to avoid squeezing damage to the outer wall of the packaging box.

[0036] In actual use, the height adjustment unit 3 adjusts the height of the side baffle 2 (i.e., the height distance between the side baffle 2 and the conveyor belt), and the width adjustment unit 4 adjusts the width of the side baffle 2 (i.e., the width distance between the two side baffles 2). This adapts to packaging boxes of different sizes, preventing chaotic arrangement, shaking, tipping, or even falling off of the packaging boxes during transport due to their excessive height or narrowness. Simultaneously, the symmetrically arranged correction units 5 on both sides use their swivel wheels 51 to straighten the packaging boxes, ensuring a neat and consistent arrangement for subsequent processing such as sealing or marking / coding. It is understood that in actual use, the minimum distance between the symmetrically arranged swivel wheels 51 on both sides is adapted to the width of the packaging box. That is, when the packaging box passes the swivel wheels 51, at least one side of each box contacts the outer edge of the swivel wheel 51, and the corrective action of the swivel wheels 51 adjusts the corrected position, making the width direction of the packaging box perpendicular to its conveying direction. In addition, since the accuracy requirements for correction are not very high, the minimum distance between the left and right swing wheels 51 is often greater than the width of the packaging box, so as to ensure that correction and alignment are achieved while reducing the risk of squeezing damage to the packaging box.

[0037] refer to Figure 3As shown, the correction unit 5 includes a fixed base 52 fixedly mounted on the side wall of the support frame 1, at least one guide rod 53 vertically fixedly mounted on the fixed base 52, and a guide seat 54 sleeved around the guide rod 53, which can move laterally left and right. The guide seat 54 is specifically an inverted "L"-shaped seat. The sway wheel 51 is rotatably mounted vertically on the guide seat 54, so that the distance between the outer edge of the sway wheel 51 and the inner side wall of the side baffle 2 can be changed by adjusting the left and right lateral position of the guide seat 54, i.e., the distance the sway wheel 51 extends inward, thereby changing the distance between the sway wheels 51 on the left and right sides to accommodate packaging boxes of different sizes. Furthermore, the correction unit 5 also includes an adjusting screw 55 rotatably mounted vertically on the fixed base 52, and a limiting seat 56 fixedly mounted at the end of the guide rod 53. Two guide rods 53 are provided and arranged in parallel. The two ends of each guide rod 53 are fixedly connected to a fixed base 52 and a limiting base 56, respectively. An adjusting screw 55 is arranged parallel to the guide rods 53 and is located between the two guide rods 53. The adjusting screw 55 movably passes through the limiting base 56 and extends outward, with an adjusting knob 57 fixedly connected to its end. A guide seat 54 movably passes through the guide rods 53 and the adjusting screw 55 and is threadedly connected to the adjusting screw 55. Rotating the adjusting knob 57 drives the adjusting screw 55 to rotate, thereby causing the guide seat 54 and the sway wheel 51 to move laterally left and right. Furthermore, the correction unit 5 also includes a sway motor 58 fixedly mounted on the guide seat 54. The sway wheel 51 is fixedly mounted at the end of the output shaft of the sway motor 58, so that the sway motor 58 drives the sway wheel 51 to rotate actively. In actual use, when the sway wheel 51 relies solely on passive rotation to achieve the correction function, occasional blockages may occur, causing some packaging boxes to be unable to pass smoothly. Therefore, a sway motor 58 is configured to actively drive the sway wheel 51 to rotate. This ensures that when the sway wheel 51 contacts the packaging box, it generates a tangential force, guaranteeing the smooth passage of the packaging box and completing the correction. It should be noted that the left and right sway motors 58 rotate in opposite directions but at the same speed. Furthermore, the rotation speed of the sway motors 58 is matched to the speed of the conveyor belt, ensuring that the sway wheel 51 does not rotate too fast or too slow, thus avoiding significant forward pushing or backward dragging forces on the packaging box.

[0038] Combination Figure 2 and Figure 5As shown, the height adjustment unit 3 includes a mounting base 31 fixedly mounted on the side wall of the main frame 11 of the support frame 1, a base 32 vertically fixedly mounted on the mounting base 31, a longitudinal rod 33 vertically extending through the base 32, and a first locking knob 34 movably mounted on the base 32. The top end of the longitudinal rod 33 is fixedly connected to the width adjustment unit 4, so that the height position of the width adjustment unit 4 and the side baffle 2 can be adjusted by raising or lowering the longitudinal rod 33. The first locking knob 34 extends into the base 32 and its end abuts perpendicularly against the surface of the longitudinal rod 33, so that the longitudinal rod 33 can be locked or released by rotating the first locking knob 34. Specifically, the first locking knob 34 and the base 32 are connected by a threaded structure. It should be noted that the contact surface between the first locking knob 34 and the longitudinal rod 33 can be provided with a grooved structure or a raised structure to increase friction (not shown in the figure) to increase the clamping force when the first locking knob 34 and the longitudinal rod 33 are locked together, to prevent the longitudinal rod 33 from sliding and deviating, and to improve the stability and reliability of locking. Given that this is a mature existing technology in the field, its specific structure and principle will not be described in detail here.

[0039] Combination Figure 2 and Figure 4 As shown, the width adjustment unit 4 includes a positioning block 41 fixedly mounted at the top end of the longitudinal rod 33, a transverse rod 42 horizontally extending through the positioning block 41, and a second locking knob 43 movably mounted on the positioning block 41. The inner end of the transverse rod 42 is fixedly connected to the side baffle 2, so that the width position of the side baffle 2 can be adjusted by pushing the transverse rod 42 inward or pulling it outward, thereby changing the width spacing between the side baffles 2 arranged opposite to each other on the left and right sides, thus adapting to packaging boxes of different widths. The second locking knob 43 extends into the positioning block 41 and its end abuts perpendicularly to the surface of the transverse rod 42, so that the transverse rod 42 can be locked or released by rotating the second locking knob 43. Specifically, the second locking knob 43 and the positioning block 41 are movably connected by a threaded structure. In addition, the contact and pressing structure between the second locking knob 43 and the transverse rod 42 can be referred to the specific setting of the first locking knob 34 described above, which will not be elaborated further here.

[0040] refer to Figure 2As shown, the support frame 1 includes a main frame 11 with a conveyor belt and base rods 12 fixedly mounted at the bottom of the main frame 11. Several base rods 12 are arranged at intervals along the length of the main frame 11. Specifically, each base rod 12 is an inverted "Y"-shaped rod, and its bottom is provided with an adjusting seat 13 threadedly connected to it. This allows the overall height of the support frame 1 to be changed by adjusting the length of the adjusting seat 13 extending into the bottom of the base rod 12. Furthermore, the support frame 1 is equipped with a drive assembly (not shown in the figure) for driving the conveyor belt. Given that this is mature prior art in the field, its specific structure and principle will not be described here, and it should not be considered a factor affecting the normal implementation of this embodiment.

[0041] Furthermore, in combination Figure 2 and Figure 4 As shown, the side baffle 2 includes an inner layer plate 21 located on the inner side and a support plate 22 fixedly embedded on the outer side of the inner layer plate 21. Specifically, the outer side of the inner layer plate 21 is provided with a receiving groove arranged along its length, that is, the cross-section of the inner layer plate 21 is "U"-shaped. The support plate 22 is fixedly embedded in the receiving groove. The inner layer plate 21 is made of hard plastic or other rubber materials to avoid scratching, collision and wear on the packaging box, while the support plate 22 is made of a tough metal material or aluminum alloy to ensure the overall rigidity and stability of the side baffle 2. It should be noted that the inner surface of the inner layer plate 21 is preferably made of a material with low friction to avoid large friction when in contact with the outer surface of the packaging box, which could cause the packaging box to shift or even tip over.

[0042] Optionally, in some embodiments, a slider 421 is fixedly connected to the inner end of the transverse rod 42, and a transverse groove 221 is provided on the outer side of the support plate 22 of the side baffle 2 along its length direction. The slider 421 is horizontally reciprocating within the transverse groove 221 to facilitate adjustment of the installation position of the side baffle 2 (position along the length of the support frame 1). It should be noted that a certain sliding damping is provided between the slider 421 and the groove. Only when sufficient external force is applied will the slider 421 slide relative to the groove to avoid the side baffle 2 sliding off. The relative sliding here includes sliding along the length direction of the support frame 1 and sliding along the width direction of the support frame 1, that is, the movement of the slider 421 disengaging from the transverse groove 221, which can be understood as an approximate snap-fit ​​and disengagement movement of a buckle structure. In addition, the transverse groove 221 and the slider 421 can be configured as matching dovetail grooves or T-grooves, so that the slider 421 and the transverse groove 221 can only slide relative to each other along the length of the support frame 1.

[0043] In summary, the packaging box conveying device with correction function provided by this utility model can straighten the conveyed packaging box materials, ensuring that the packaging boxes are arranged neatly and uniformly, avoiding the impact of scattered packaging boxes on subsequent packaging processing, and reducing the risk of packaging boxes tilting, falling or even detaching during the conveying process, thus improving the stability and reliability of the conveying. In addition, it is applicable to packaging box materials of different specifications and sizes, and has strong practicality and wide applicability.

[0044] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
