Description

Technical Field

[0001] This utility model belongs to the technical field of luggage and bag load-bearing plate manufacturing, specifically relating to a luggage and bag honeycomb cardboard reinforcing rib installation device. Background Technology

[0002] Bags and luggage, as indispensable items in modern life, are widely used for travel, daily commutes, and various other occasions. With the improvement of people's living standards and the increase in travel frequency, the demand for bags and luggage continues to grow. Bags and luggage not only need to have basic storage functions, but also need to be lightweight, durable, aesthetically pleasing, and safe. Especially during travel, the load-bearing capacity and internal structure design of bags and luggage become particularly important.

[0003] In the design and manufacturing of luggage, the load-bearing plate is a crucial component. It affects the overall stability and durability of the luggage. Load-bearing plates are typically located at the bottom and sides of the luggage to support the weight of the contents and maintain the luggage's shape. The material and structure of the load-bearing plate directly affect the strength and weight of the luggage; therefore, using high-performance materials and a rational structural design are essential.

[0004] In luggage, the load-bearing panels are typically designed with a multi-layered structure, with honeycomb paperboard as the core material. Due to its lightweight and high strength, honeycomb paperboard is an ideal choice for load-bearing panels. The hexagonal honeycomb structure provides excellent strength with minimal weight, ensuring stability under heavy loads. Furthermore, the production process of honeycomb paperboard is relatively environmentally friendly, making the luggage more aligned with sustainable development requirements to some extent.

[0005] However, larger bags and luggage require higher strength for the load-bearing boards, which existing honeycomb cardboard cannot meet. Replacing the core material of the load-bearing board would not only require more expensive materials but also necessitate setting up a new production line, resulting in high costs. Therefore, adding reinforcing ribs to the honeycomb cardboard is an effective way to significantly improve the strength of the load-bearing board without major modifications to the existing production line.

[0006] However, there is currently no equipment for placing reinforcing ribs into the honeycomb cells of bag honeycomb cardboard in an orderly and rapid manner, and research and development is urgently needed. Utility Model Content

[0007] Based on the technical problems mentioned in the background art, this utility model proposes a device for installing reinforcing ribs on honeycomb cardboard for bags.

[0008] The present invention adopts the following technical solution:

[0009] A device for installing reinforcing ribs on honeycomb paperboard for bags includes a conveyor table and a reinforcing rib installation structure. The conveyor table holds the honeycomb paperboard and can move it in one direction. The honeycomb paperboard has honeycomb holes. The reinforcing rib installation structure includes a hopper unit, a discharge roller unit, a conveying channel unit, and an intermittent guide roller unit. Strip-shaped reinforcing ribs can be stacked in the hopper unit. The discharge roller unit is located at the outlet of the hopper unit. The conveying channel unit has a conveying pipe adapted to the shape of the honeycomb holes on the honeycomb paperboard. The tube has an opening at the bottom, which is located above the conveyor table. The honeycomb paperboard for bags can pass through the opening at the bottom of the conveyor tube. The diameter of the reinforcing rib is smaller than the diameter of the conveyor tube. The intermittent guiding roller unit includes an intermittent guiding roller. The roller body of the intermittent guiding roller can intermittently penetrate into the conveyor tube, so that the inner diameter of the conveyor tube is reduced to a size smaller than the diameter of the reinforcing rib. The diameter of the conveyor tube is smaller than the inner diameter of the honeycomb hole. The feeding roller unit can rotate to roll the reinforcing rib from the hopper unit to the top of the conveyor tube. After passing through the conveyor tube, the reinforcing rib falls from the bottom of the conveyor tube into the honeycomb hole of the honeycomb paperboard for bags.

[0010] To optimize the technical solution, the following further measures will be taken:

[0011] The aforementioned transmission platform includes a support frame, on which a conveyor roller and a conveyor motor are mounted. The conveyor motor is fixedly installed on the support frame, and the conveyor roller is located on the upper surface of the support frame. The conveyor motor is connected to the conveyor roller for transmission. The conveyor roller clamps the honeycomb cardboard of the bag and can drive the honeycomb cardboard of the bag to move in one direction.

[0012] The aforementioned hopper unit includes a hopper with an upper feeding opening at the top and a lower feeding opening at the bottom. The upper feeding opening has a large opening, while the lower feeding opening has a small opening. The width of the lower feeding opening is the same as the width of the honeycomb cardboard for the luggage.

[0013] The aforementioned feeding roller unit includes a feeding roller and a feeding roller drive motor. The feeding roller is horizontally positioned at the hopper opening, with its axial direction aligned with the width of the hopper opening. The feeding roller drive motor is fixedly mounted on the side of the hopper and is connected to the feeding roller in a transmission manner. The surface of the feeding roller is covered with felt. The feeding roller partially penetrates into the hopper opening, so that when the reinforcing ribs flow out of the hopper opening, they are blocked by the felt. When the feeding roller rotates, the felt can roll up the reinforcing ribs through friction and flow out of the hopper opening.

[0014] The aforementioned conveying channel unit includes a left side plate, a right side plate, and channel ribs. The left and right side plates are arranged in parallel, with the front ends of the left and right side plates closed and connected, and the rear ends of the left and right side plates also closed, forming a vertically continuous conveying space between the left and right side plates. The upper end of the conveying space connects to the hopper opening. The reinforcing ribs flowing from the hopper opening fall into the conveying space. The gap between the left and right side plates is greater than the diameter of one reinforcing rib but less than the diameter of two reinforcing ribs. There are several channel ribs, evenly spaced along the width of the conveying channel unit. The channel ribs are fixedly located in the lower half of the conveying space, and a conveying pipe is formed between adjacent channel ribs. The diameter of the conveying pipe is greater than the diameter of one reinforcing rib but less than the diameter of two reinforcing ribs. Two rows of shaping blocks are arranged within the conveying space, evenly spaced along the width direction. Adjacent shaping blocks in the width direction are located in different rows, and the distance between adjacent shaping blocks in the width direction is half the length of the reinforcing rib.

[0015] The upper end of the aforementioned channel rib gradually converges to form a sharp tip, thereby causing the upper end of the delivery pipe to flare outwards.

[0016] The lower side of the left or right side plate is provided with an intrusion opening extending in the width direction. The intrusion opening is connected to the conveying pipe. The roller body of the intermittent guide roller intermittently enters the conveying pipe through the intrusion opening, thereby intermittently blocking the reinforcing rib from passing through the conveying pipe.

[0017] The aforementioned intermittent conducting roller unit also includes an intermittent conducting roller drive motor, which is fixedly installed on the outer side of the left or right side plate and is connected to the intermittent conducting roller drive motor.

[0018] The intermittent guide rollers described above are arranged laterally, with the axial direction being the width direction of the conveying channel unit. The intermittent guide rollers are provided with spaced long ends and short ends. When the intermittent guide rollers rotate, the long ends and short ends pass through the intrusion openings in sequence. When the long end passes through the intrusion opening, the long end enters the conveying pipe. When the short end passes through the intrusion opening, the short end cannot enter the conveying pipe due to insufficient length.

[0019] The length of the aforementioned reinforcing rib is greater than half the thickness of the honeycomb cardboard for bags and less than the thickness of the honeycomb cardboard for bags, and the two ends of the reinforcing rib are sharp.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention relates to a device for installing reinforcing ribs in honeycomb paperboard for bags. Through a hopper unit, a feeding roller unit, a conveying channel unit, and an intermittent guiding roller unit arranged in sequence, strip-shaped reinforcing ribs are implanted into the honeycomb holes of the honeycomb paperboard for bags, thereby significantly increasing the load-bearing capacity of the honeycomb paperboard in the thickness direction.

[0022] The feeding roller unit of this invention can control the number of reinforcing ribs entering the conveying channel unit by adjusting the rotation speed. The conveying channel unit can adjust the orientation of the reinforcing ribs and arrange them into a shape corresponding to the honeycomb holes. The intermittent guiding roller unit can control the time and frequency at which the arranged reinforcing ribs fall from the lower end of the conveying pipe by adjusting the rotation speed, so that the timing of the reinforcing ribs falling is matched with the speed of the honeycomb cardboard moving on the conveyor table, ensuring that the reinforcing ribs fall neatly and uniformly into the honeycomb holes. This invention has a high degree of automation and high efficiency in installing reinforcing ribs. Attached Figure Description

[0036] like Figure 1-7 As shown, the main structure of the honeycomb cardboard reinforcing rib installation device of this utility model includes a conveyor table 1, a hopper unit 3, a feeding roller unit 4, a conveying channel unit 5, an intermittent guiding roller unit 6, and reinforcing ribs 7.

[0037] The transfer table 1 includes a support frame 11, transfer rollers 12, and a transfer motor 13. The support frame 11 is a stainless steel bracket. There are two transfer rollers 12 at the front and two at the back. The two front transfer rollers 12 clamp the honeycomb cardboard 2 of the bag, and the two rear transfer rollers 12 clamp the honeycomb cardboard 2 of the bag. The transfer motor 13 drives the transfer rollers 12 to rotate, and the transfer rollers 12 move the honeycomb cardboard 2 of the bag. Figure 1 In this process, the honeycomb cardboard 2 for bags moves from right to left. The upper and lower conveyor rollers 12 are connected by a figure-eight belt, so they can rotate in opposite directions, thereby driving the honeycomb cardboard 2 for bags to move.

[0038] Hopper unit 3 includes hopper 31, which has openings at both the top and bottom ends, from which... Figure 1 It can be seen that the opening of the feeding hopper 32 is large, while the opening of the discharging hopper 33 is small. The width of the discharging hopper 33 is the same as the width of the honeycomb cardboard 2.

[0039] The feeding roller unit 4 includes a feeding roller 41 and a feeding roller drive motor 42, such as Figure 2 and 6As shown, the feeding roller 41 is laterally positioned at the hopper opening 33, and the axial direction of the feeding roller 41 is along the width direction of the hopper opening 33. In this embodiment, the width direction is... Figure 6 The left and right directions in the middle, and also Figure 8 The feed roller drive motor 42 is fixedly installed on the side of the hopper 31. The feed roller drive motor 42 is connected to the feed roller 41 for transmission. The surface of the feed roller 41 is covered with felt, and the lower half of the feed roller 41 is located in the feed hopper opening 33. From Figure 2 It can be seen that the discharge roller 41 obstructs the natural flow of the reinforcing rib 7 from the discharge hopper opening 33. Figure 6 It can be seen that after the feeding roller 41 rotates, it can roll out the reinforcing rib 7.

[0040] The conveying channel unit 5 is a rectangular hollow plate with openings at the top and bottom. Therefore, its outer shell consists of a left side plate 52, a right side plate 53, and front and rear sealing plates (not shown in the figure). The space inside the rectangular hollow plate is the conveying space, such as... Figure 5 As shown, the thickness of the conveying space is greater than the diameter of one reinforcing rib 7 but less than the diameter of two reinforcing ribs 7. The conveying space is nearly vertical. Two rows of shaping blocks 57 are arranged in the conveying space. These two rows of shaping blocks 57 are equally spaced along the width direction, and adjacent shaping blocks 57 are located in different rows in the width direction. The distance between adjacent shaping blocks 57 in the width direction is half the length of the reinforcing rib 7. The presence of the shaping blocks 57 will cause the reinforcing ribs 7 that fall laterally to fall onto the shaping blocks 57 and then be forced to become vertical or inclined, and continue to fall from the gap between the shaping blocks 57. This makes the reinforcing ribs 7 in the conveying space vertical or nearly vertical. The channel ribs 54 are equally spaced along the width direction of the conveying channel unit 5. The channel ribs 54 are fixedly set in the lower half of the conveying space. A conveying pipe 51 is formed between adjacent channel ribs 54. The diameter of the conveying pipe 51 is greater than the diameter of one reinforcing rib 7 but less than the diameter of two reinforcing ribs 7. An outwardly flared opening 55 is formed at the upper end of the conveying pipe 51. With this setup, the reinforcing ribs 7 entering the conveying space will fall smoothly into the conveying pipe 51. The reinforcing ribs 7 in a conveying pipe 51 can only be arranged end to end. If a conveying pipe 51 is overflowing, the reinforcing ribs 7 will not be able to fall into that conveying pipe 51 and will naturally fall into the adjacent conveying pipe 51.

[0041] like Figure 3As shown, an intrusion opening 56 extending along the width direction is provided on the lower part of the side of the left side plate 52 or the right side plate 53. This intrusion opening 56 connects to the conveying pipe 51, and the roller body of the intermittent guiding roller 61 intermittently enters the conveying pipe 51 through the intrusion opening 56. The intermittent guiding roller drive motor 62 is fixedly installed on the outer side of the left side plate 52 or the right side plate 53, and the intermittent guiding roller drive motor 62 is connected to the intermittent guiding roller 61 for transmission. The cross-sectional shape of the intermittent guiding roller 61 is similar to that of a circular running track, with a long end and a short end. When the intermittent guiding roller 61 rotates, the long end and the short end pass through the intrusion opening 56 in sequence. When the long end passes through the intrusion opening 56, the long end enters the conveying pipe 51. When the short end passes through the intrusion opening 56, the short end cannot enter the conveying pipe 51 due to insufficient length.

[0042] The length of the reinforcing rib 7 is greater than half the thickness of the honeycomb cardboard 2 and less than the thickness of the honeycomb cardboard 2. The reinforcing rib 7 has sharp ends.

[0043] from Figure 8 It can be seen that the honeycomb holes 21 on the honeycomb cardboard 2 of the bag are arranged periodically in the length direction, with two adjacent rows of honeycomb holes 21 forming one cycle. Therefore, the arrangement of the conveying pipe 51 of this utility model is adapted to the honeycomb holes 21 in one cycle. The lower end face of the conveying pipe 51 is as follows: Figure 7 As shown, each column of conveying pipes 51 corresponds to one hopper unit 3, one discharge roller unit 4, one conveying channel unit 5, and one intermittent guiding roller unit 6. Therefore, this utility model has two hopper units 3, two discharge roller units 4, two conveying channel units 5, and two intermittent guiding roller units 6, and their positions are as follows. Figure 1 As shown.

[0044] The working principle of this utility model is as follows:

[0045] Turn on the conveyor motor 13, causing the conveyor roller 12 to move the honeycomb cardboard 2 on the conveyor table 1. The user puts reinforcing ribs 7 into the hopper 31. The arrangement of the reinforcing ribs 7 is not required, but a certain number of reinforcing ribs 7 must be maintained in the hopper 31. The discharge roller drive motor 42 drives the discharge roller 41 to rotate at a predetermined speed, so that the reinforcing ribs 7 fall into the conveying channel unit 5 in a predetermined quantity and in an orderly manner, ensuring that the conveying channel unit 5 is not congested and that there are no missing reinforcing ribs 7. After entering the conveying space, the reinforcing ribs 7 will fall a certain distance and then contact the shaping block 57, vertically... Straight reinforcing ribs 7 pass directly through the gaps in the shaping blocks 57, while horizontal reinforcing ribs 7 are blocked by the shaping blocks 57 and turned into a vertical or inclined state before entering a certain conveying pipe 51. The conveying pipe 51 can accommodate multiple reinforcing ribs 7, but the reinforcing ribs 7 inside the conveying pipe 51 are in a state of end to end. The intermittent guide roller drive motor 62 drives the intermittent guide roller 61 to rotate. When the long end of the intermittent guide roller 61 enters the conveying pipe 51, it will press down on the reinforcing rib 7, preventing it from falling. When the short end of the intermittent guide roller 61 enters the conveying pipe 51, the reinforcing rib 7 can fall smoothly. The time it takes for the long and short ends of the intermittent guide roller 61 to switch once is just enough for one reinforcing rib 7 to pass through. Therefore, by setting the rotation speed of the intermittent guide roller drive motor 62, it is possible to control the delivery pipe 51 to drop one reinforcing rib 7 each time. The timing of the reinforcing rib 7 falling is exactly when the honeycomb holes 21 of the bag honeycomb paperboard 2 move directly below the delivery pipe 51. At this time, the reinforcing rib 7 falls smoothly into the honeycomb holes 21 of the bag honeycomb paperboard 2. Each time it falls, the reinforcing rib 7 fills two rows of honeycomb holes 21. And the time interval between two falls is exactly the length of two rows of honeycomb holes that the bag honeycomb paperboard 2 can move forward.

[0046] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
