Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology and relates to a packaging machine's feeding mechanism for a tube to be packaged. Background Technology

[0002] A rubber tube is a container used to store adhesive, typically made of aluminum or plastic. When filling the tube, the sealed end faces downwards, and the open end faces upwards; the adhesive is poured in from the end. After the adhesive is filled, the end of the tube is folded multiple times to create a seal, or heat-sealed. For example, a glue filling machine disclosed in Chinese patent literature [publication number: CN207843487U] uses a push rod to eject the tube from bottom to top after the end is sealed. The tube is then placed into a packaging box.

[0003] Existing packaging machines, such as the highly integrated fully automatic packaging production equipment disclosed in Chinese patent literature [publication number: CN115959349A], include a frame and a feeding mechanism, a box feeding mechanism, a pushing mechanism, a box pressing mechanism, and a flap insertion mechanism mounted on the frame. The feeding mechanism is used to transport the items to be packaged from the loading port to the discharge port. The feeding mechanism includes a first conveyor belt and a second conveyor belt. The first conveyor belt is rotatably arranged from the loading port to the discharge port and has at least one first partition perpendicular to the belt conveying direction. The second conveyor belt is arranged parallel to the first conveyor belt and has at least one second partition, with each second partition spaced apart from the first partition. The items to be packaged are located between the first and second partitions, and the first and second conveyor belts move simultaneously to transport the items.

[0004] Before filling, the tubing is a cylindrical tube of uniform diameter with rounded ends. After filling, the end of the tubing is sealed. This results in the tubing head remaining round, while the tail is flattened by compression; the width of the tubing at the head is equal to its diameter, and the width at the tail is half the circumference of the head. The packaging box is a rectangular prism with a square cross-section. When inserting the tubing into the box, it needs to be rotated 45° to the side, meaning the width of the tubing tail lies along the diagonal of the square box. Therefore, when using the aforementioned packaging machine to package rubber tubes, according to trigonometric functions, the width between the first and second partitions is the width of the tube tail divided by 1.414, approximately 1.11 times the tube diameter. If the tube is rotated 45° to the side before being placed between the first and second partitions, the tube will maintain this position. If the tube is not rotated 45° before being placed between the first and second partitions, the tube head will be embedded between them, while the tube tail will be blocked by the upper surfaces of the first and second partitions, meaning the tube tail will be positioned upwards above them. Since the aforementioned packaging machine lacks a mechanism to rotate the tube, it must be manually rotated before being placed between the first and second partitions, resulting in a decrease in the machine's efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a feeding mechanism for the packaging tube of a packaging machine, which solves the technical problem of low working efficiency of the feeding mechanism for the packaging tube in existing packaging machines.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A packaging machine's tube feeding mechanism includes a horizontally arranged first conveyor belt. A plurality of partitions are fixed on the first conveyor belt, spaced apart along its length and perpendicular to it. The length of each partition is along the width of the first conveyor belt. The mechanism is characterized by a linear drive component and a fixed housing fixed directly above the feed end of the first conveyor belt, arranged along its length. The fixed housing is a vertically penetrating cuboid cylinder, its length along the width of the first conveyor belt. A drawer plate is horizontally inserted into the fixed housing to divide the internal channel. The linear drive component is connected to the drawer plate and can drive the drawer plate to move and open the internal channel of the fixed housing.

[0008] A downward-sloping U-shaped chute can be placed at the discharge position of the glue filling machine, with the lower end of the U-shaped chute positioned above the fixed housing. This allows the discharged glue tube to slide along the U-shaped chute into the fixed housing. During the packaging machine's operation, a pull plate blocks the channel within the fixed housing. The glue tube to be packaged enters the fixed housing and falls onto the pull plate, at which point the tail of the glue tube is horizontal. Then, the first conveyor belt moves, positioning the two partitions directly below the fixed housing. Subsequently, a linear drive drives the pull plate to move outward. During this outward movement, one side of the glue tube is initially suspended in the air. When the center of gravity of the glue tube is suspended, it rotates sideways and falls between the two partitions, where it is positioned and maintained at approximately a 45° side-rotation. Next, the linear drive drives the pull plate to reset, re-blocking the channel within the fixed housing. Then, the first conveyor belt transports the glue tube forward, positioning the other two adjacent partitions directly below the fixed housing. During the first conveyor belt transport, another hose to be packaged falls onto the drawer plate. After the other two partitions are directly below the fixed housing, the drawer plate moves outward again, and this cycle is repeated. The linear drive, fixed housing, and drawer plate configuration enable automatic lateral rotation of the hose, eliminating the need for manual rotation and thus improving the packaging machine's efficiency.

[0009] In the above-mentioned packaging machine's tube feeding mechanism, the tops of the two side walls along the length of the fixed shell each have an inclined wall that slopes outward from bottom to top, and the drawer plate is located below the inclined wall. The inclined wall widens the upper port of the fixed shell and serves as a guide, allowing the tube entering the fixed shell to smoothly fall onto the drawer plate, thereby achieving automatic side rotation of the tube and improving the working efficiency of the packaging machine.

[0010] In the above-mentioned packaging machine's tube feeding mechanism, there are several drawer plates arranged sequentially in the vertical direction, and several linear drive components are connected to each drawer plate.

[0011] During operation, the hose first falls onto the topmost drawer plate. Then, the first drawer plate moves outwards, and the hose falls onto the second drawer plate. Afterwards, the first drawer plate resets, the second drawer plate moves outwards, and the next hose falls onto the first drawer plate. The hose on the second drawer plate falls onto the third drawer plate. This sequential action of the linear drive mechanism causes the hose to descend layer by layer. Finally, the bottom drawer plate moves, causing the hose to rotate sideways and fall between the two partitions. This multi-layer drawer plate structure serves two purposes: it buffers the feed and shortens the distance between the partitions and the bottom drawer plate. This ensures the hose is inserted into the space between the partitions in a side-rotated position, preventing it from falling for too long after rotating and changing its posture. This ensures the packaging machine operates smoothly and efficiently.

[0012] In the above-mentioned packaging machine's tube feeding mechanism, a second conveyor belt is also provided on one side of the first conveyor belt's feed end. The discharge end of the second conveyor belt is located above the first conveyor belt's feed end and is correspondingly positioned to the upper end of the fixed shell.

[0013] The lower end of the U-shaped chute can be moved above the feed end of the second conveyor belt, allowing the hose to be transported to the upper end of the fixed housing via the second conveyor belt. When the pull plate is opened, the second conveyor belt can be slowed down to prevent the next hose from passing directly through the fixed housing. The second conveyor belt provides a buffer for the hose feed, ensuring orderly operation and high efficiency of the packaging machine.

[0014] In the above-mentioned packaging machine's tube feeding mechanism, two baffles are provided above the second conveyor belt along the length of the second conveyor belt. The two baffles are spaced apart and both baffles are perpendicular to the upper surface of the second conveyor belt. One end of the two baffles is located above the side wall of the fixed shell near the second conveyor belt.

[0015] Align the lower end of the U-shaped chute with the space between the two baffles, allowing the rubber hose to fall between them for conveying. The baffles act as retainers and guides, preventing the hose from slipping off the sides of the second conveyor belt and ensuring it smoothly enters the fixed housing. This allows the packaging machine to operate in an orderly manner and maintains its efficiency.

[0016] In the aforementioned packaging machine's tube feeding mechanism, the second conveyor belt includes a horizontally positioned horizontal section and an inclined section that slopes downwards relative to the horizontal section. The discharge end of the second conveyor belt is located on the horizontal section. The inclined section is designed to accommodate the height of the U-shaped chute, thereby better connecting the fixed shell and the U-shaped chute. The horizontal section adjusts the posture of the tube to be horizontal, facilitating the tube's smooth landing on the drawer plate and maintaining its horizontal position, preparing for subsequent lateral rotation. This achieves automatic lateral rotation of the tube, improving the packaging machine's working efficiency.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The automatic side rotation of the tube can be achieved by using a linear drive, a fixed housing, and a drawer plate, eliminating the need for manual rotation and thus improving the working efficiency of the packaging machine. Attached Figure Description

Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] Example 1

[0024] like Figure 1 As shown, a packaging machine's tube feeding mechanism includes a horizontally arranged first conveyor belt 1. Several partitions 2 are fixed on the first conveyor belt 1, spaced apart along its length and perpendicular to it. The length of each partition 2 is along the width of the first conveyor belt 1. Two adjacent partitions 2 form a group for positioning the tubes to be packaged, and the distance between two partitions 2 in a group is 1.11 times the tube diameter. A frame is fixed to the ground, and side frames are fixedly connected to the frame on both sides of the first conveyor belt 1. A mounting base 9, fixed to the side frames, is located directly above the feeding end of the first conveyor belt 1. The mounting base 9 has a through hole 9a. A linear drive 3 and a fixing shell 4, arranged along the length of the first conveyor belt 1, are fixed to the upper surface of the mounting base 9. The fixing shell 4 is a vertically penetrating rectangular tube, with its lower end opposite the through hole 9a. The length of the fixing shell 4 is along the width of the first conveyor belt 1. A drawer plate 5 is horizontally inserted into the fixed housing 4 to separate the internal channel of the fixed housing 4. A linear drive 3 is connected to the drawer plate 5 and can drive the drawer plate 5 to move and open the internal channel of the fixed housing 4. The linear drive 3 is a cylinder or a hydraulic cylinder.

[0025] like Figure 1 and Figure 2 As shown, there are three drawer plates 5 arranged sequentially in the vertical direction, and three linear drive components 3 connected to each drawer plate 5 in a corresponding manner. The three linear drive components 3 are stacked vertically and fixed on the mounting base 9. The top of the two side walls along the length of the fixed housing 4 has an inclined wall 4a that slopes outward from bottom to top, and the drawer plates 5 are located below the inclined wall 4a.

[0026] like Figure 1 and Figure 2As shown, a second conveyor belt 6 is also provided on one side of the feeding end of the first conveyor belt 1. The conveying direction of the second conveyor belt 6 is perpendicular to the conveying direction of the first conveyor belt 1. The discharge end of the second conveyor belt 6 is located above the feeding end of the first conveyor belt 1 and is correspondingly positioned to the upper end of the fixed housing 4. Two baffles 7 are provided above the second conveyor belt 6, arranged along the length of the second conveyor belt 6. The two baffles 7 are spaced apart and are perpendicular to the upper surface of the second conveyor belt 6. One end of the two baffles 7 is located above the side wall of the fixed housing 4 near the second conveyor belt 6 and is inserted between the two inclined walls 4a. The second conveyor belt 6 includes a horizontally arranged horizontal section 6a and an inclined section 6b that is inclined downward relative to the horizontal section 6a. The discharge end of the second conveyor belt 6 is located on the horizontal section 6a. Two baffles 7 are located above the horizontal section 6a. Two auxiliary plates 8 are also installed above the inclined section 6b, extending along its length. The two auxiliary plates 8 are spaced apart, and both baffles 7 are perpendicular to the upper surface of the inclined section 6b. Each auxiliary plate 8 corresponds to one baffle 7. Profile tubes are installed on both sides of the second conveyor belt 6, and these tubes are fixed to the frame. Connecting rods are fixed to the outer surfaces of both the baffles 7 and auxiliary plates 8. Support frames are fixed to the outer ends of the connecting rods and are fixed to the profile tubes. There is a gap between the lower surface of the baffle 7 and the upper surface of the horizontal section 6a of the second conveyor belt 6, and a gap also exists between the lower surface of the auxiliary plate 8 and the upper surface of the inclined section 6b of the second conveyor belt 6.

[0027] A downward-sloping U-shaped chute can be placed at the discharge position of the glue filling machine, with the lower end of the U-shaped chute positioned above the feed end of the second conveyor belt 6 and between the two auxiliary plates 8. The glue tube exiting the glue filling machine slides down the U-shaped chute and falls onto the second conveyor belt 6, with the length direction of the glue tube roughly the same as the length direction of the second conveyor belt 6. Then, the glue tube is conveyed to the upper end of the fixed shell 4 by the second conveyor belt 6. The glue tube first falls onto the topmost first-layer drawer plate 5, with the length direction of the glue tube roughly the same as the length direction of the fixed shell 4 and the tail of the glue tube being horizontal. Then, the first-layer drawer plate 5 moves outward, and the glue tube falls onto the second-layer drawer plate 5. After that, the first-layer drawer plate 5 resets, the second drawer plate 5 moves outward, and the next glue tube continues to fall onto the first-layer drawer plate 5. The glue tube on the second-layer drawer plate 5 falls onto the third-layer drawer plate 5. In this way, after the linear drive 3 moves sequentially, the glue tube descends layer by layer. During the operation of the drawer plate 5, the first conveyor belt 1 moves, positioning the two partitions 2 directly below the fixed housing 4. When the bottom drawer plate 5 moves, as it moves outward, one side of the tube is initially suspended in the air. Once the tube's center of gravity is suspended, it rotates sideways and falls between the two partitions 2, where it is positioned and maintained at approximately a 45° side-rotation. Then, the linear drive 3 drives the drawer plate 5 to reset, re-severing the channel within the fixed housing 4. The first conveyor belt 1 then transports the tube forward, positioning the other two adjacent partitions 2 directly below the fixed housing 4. This process is repeated sequentially. The linear drive 3, fixed housing 4, and drawer plate 5 enable automatic side-rotation of the tube, eliminating the need for manual rotation and thus improving the packaging machine's efficiency.

[0028] Example 2

[0029] Based on Embodiment 1, the structure is simplified by omitting the second conveyor belt 6 and only installing a drawer 5 and a linear drive 3 on the fixed housing 4. The lower end of the U-shaped chute is located above the fixed housing 4, so that the glue tube after dispensing from the glue filling machine can slide directly into the fixed housing 4 along the U-shaped chute. During the operation of the packaging machine, the drawer plate 5 blocks the channel inside the fixed shell 4. The tubing to be packaged enters the fixed shell 4 and falls onto the drawer plate 5, at which point the tail of the tubing is horizontal. Then, the first conveyor belt 1 moves, positioning the two partitions 2 directly below the fixed shell 4. Next, the linear drive 3 drives the drawer plate 5 outward. During this outward movement, one side of the tubing is initially suspended in the air. When the center of gravity of the tubing is suspended, it rotates sideways and falls between the two partitions 2, where it is positioned and maintained at approximately a 45° sideways angle. Then, the linear drive 3 drives the drawer plate 5 to reset, re-blocking the channel inside the fixed shell 4. The first conveyor belt 1 then transports the tubing forward, positioning the other two adjacent partitions 2 directly below the fixed shell 4. During the transport process by the first conveyor belt 1, another tubing to be packaged falls onto the drawer plate 5. After the other two partitions 2 are directly below the fixed shell 4, the drawer plate 5 moves outward again, and this cycle repeats.
