Description

Technical Field

[0001] This utility model relates to a packaging machine, specifically to a material handling machine for closing and sorting strip-shaped packaging bags. Background Technology

[0002] After production, strip-shaped packaging bags (such as small strip packages of snacks, tea, and medicine) typically require multiple processes including conveying, counting, and boxing. For example, utility model patent CN210503384U discloses a sorting machine for strip-shaped packaging bags. This sorting machine uses a lifting and conveying mechanism to send the packaging bags to a dropping mechanism, which then drops the bags onto a conveying mechanism. Finally, the conveying mechanism counts and sends a set number of packaging bags into packaging boxes, thus replacing manual labor and improving work efficiency. However, this sorting machine has a complex overall structure, especially the dropping mechanism, which is complex to control, prone to jamming, and suffers from significant instability and efficiency issues due to the dropping method. Summary of the Invention

[0003] In view of the problems existing in the prior art, this utility model innovatively provides a closing and sorting machine for strip packaging bags with higher conveying efficiency and more stable sorting.

[0004] This strip-shaped packaging bag closing and sorting machine includes a frame and a grid conveying mechanism. The grid conveying mechanism includes a grid conveyor belt and a power source for driving the grid conveyor belt to rotate. The machine is characterized by: a pushing mechanism on one side of the grid conveying mechanism, and a closing grid platform on the other side of the grid conveying mechanism opposite to the pushing mechanism; the pushing mechanism includes a pushing plate and a power source for driving the pushing plate to move back and forth; the grid grooves on the closing grid platform gradually converge from back to front, and a closing and pushing mechanism is provided above the closing grid platform to push the material forward.

[0005] The grid conveying mechanism is provided with a side-standing conveying mechanism on one side. The side-standing conveying mechanism includes a first belt mechanism and a second belt mechanism arranged side by side. The first belt mechanism includes a first belt, a first rear belt roller, and a first front belt roller. The first belt is wound around the first rear belt roller and the first front belt roller, and the first rear belt roller and the first front belt roller are both installed vertically. The second belt mechanism includes a second belt, a second rear belt roller, and a second front belt roller. The second belt is wound around the second rear belt roller and the second front belt roller. The second rear belt roller is installed horizontally, and the second front belt roller is installed vertically. The second front belt roller and the first front belt roller are close to each other on the left and right.

[0006] The second belt mechanism includes a second intermediate belt roller, which is located between the second rear belt roller and the second front belt roller, and is installed vertically.

[0007] The feeding mechanism includes a tracking moving seat and a tracking power source. The feeding plate and the feeding power source are both mounted on the tracking moving seat. The frame is equipped with a guide rail parallel to the conveying direction of the grid conveying mechanism. The tracking moving seat is slidably mounted on the guide rail. The tracking power source can drive the tracking moving seat to move.

[0008] The closing and pushing mechanism includes a pushing plate, a pushing seat, a pushing power source, and a opening power source. The pushing plate is movably mounted on the pushing seat. The opening power source is mounted on the pushing seat and can drive the pushing plate to move up and down. The pushing seat is slidably mounted on the mounting seat and can be driven to move by the pushing power source.

[0009] The movable seat is equipped with multiple push plates, which are arranged back and forth along the pushing direction. All push plates are connected to the connecting rod, and the opening power source is connected to the connecting rod transmission.

[0010] The push plate is hinged to the push seat, and all push plates are hinged to the connecting rod.

[0011] The opening power source is a cylinder, which is hinged to the push seat, and the piston rod of the cylinder is hinged to the connecting rod.

[0012] The grid channel of the closing grid platform has a buffer section and a closing section. The grid channels of the buffer section are parallel to each other, and the grid channels of the closing section gradually close together. The buffer section of the closing grid platform is close to the grid conveyor belt.

[0013] According to the present invention, a material closing and sorting machine for strip-shaped packaging bags can quickly close the counted materials through a grid conveying mechanism, a pushing mechanism, and a closing grid platform. This not only results in high conveying efficiency but also more stable material sorting. Attached Figure Description

Detailed Implementation

[0015] like Figure 1As shown, this strip-shaped packaging bag gathering and sorting machine includes a frame 1 and a grid conveyor mechanism 2. The grid conveyor mechanism 2 includes a grid conveyor belt 20 and a power source 21 that drives the grid conveyor belt 20 to rotate. As the power source 21 drives the grid conveyor belt 20 to move, at the feeding point, the packaged strip-shaped packaging bags are produced and then enter the grid positions of the grid conveyor belt 20 one by one via the conveyor belt or other means (one packaging bag is placed in each grid position). In order to gather multiple strip-shaped packaging bags on the grid conveyor belt 20 together, a pushing mechanism 4 is provided on one side of the grid conveyor mechanism 2, and a gathering grid platform 5 is provided on the other side of the grid conveyor mechanism 2 opposite to the pushing mechanism 4. Figure 3 As shown, the pushing mechanism 4 includes a pushing plate 40 and a pushing power source 41 that drives the pushing plate 40 to move back and forth; as Figure 4 As shown, the grid grooves 50 on the closing grid platform 5 gradually converge from back to front, and a closing and pushing mechanism 6 that can push materials forward is provided above the closing grid platform 5.

[0016] Its working principle is as follows: When strip-shaped packaging bags continuously enter the grid conveyor belt 20 (the number of packaging bags fed is controlled to achieve counting), and a set number of packaging bags are formed on the grid conveyor belt 20, the pushing power source 41 of the pushing mechanism 4 drives the pushing plate 40 to move forward, pushing this row of packaging bags on the grid conveyor belt 20 onto the closing grid platform 5. As the grid grooves 50 on the closing grid platform 5 gradually close from back to front, the strip-shaped packaging bags move forward under the push of the closing pushing mechanism 6 and continuously come together, finally coming out from the discharge port. In this way, multiple strip-shaped packaging bags can be closed and put into packaging bags or boxes. This method does not require a falling method, which not only improves the stability of the conveying but also makes the packaging efficiency higher.

[0017] After strip-shaped packaging bags are produced, they are usually laid flat. To allow them to stand upright and close properly for packaging, thus meeting packaging requirements, the following steps are taken: Figure 1 As shown, a side-standing conveying mechanism 3 is provided on one side of the grid conveying mechanism 2, such as... Figure 2As shown, the side-mounted conveyor mechanism 3 includes a first belt mechanism 30 and a second belt mechanism 31 arranged side by side. The first belt mechanism 30 includes a first belt 300, a first rear belt roller 301, and a first front belt roller 302. The first belt 300 is wound around the first rear belt roller 301 and the first front belt roller 302. The first rear belt roller 301 and the first front belt roller 302 are both installed vertically. The second belt mechanism 31 includes a second belt 310, a second rear belt roller 311, and a second front belt roller 312. The second belt 310 is wound around the second rear belt roller 311 and the second front belt roller 312. The second rear belt roller 311 is installed horizontally, and the second front belt roller 312 is installed vertically. The second front belt roller 312 and the first front belt roller 302 are close to each other from left to right, so that the second belt 310 gradually rises from back to front. During operation, the flat, strip-shaped packaging bag enters the second conveyor belt 310, where it is blocked by the first conveyor belt 300. As the strip-shaped packaging bag moves forward (e.g., ...), the packaging bag continues to move forward. Figure 2 (In the direction of the middle arrow), as the second belt 310 gradually rises from back to front, the strip-shaped packaging bag begins to stand upright under the action of the second belt 310 until it is sandwiched between the first belt 300 and the second belt 310. Finally, the strip-shaped packaging bag enters the grid conveyor belt 20 in an upright position. Of course, if the strip-shaped packaging bag is already upright after production, it can directly enter the grid conveyor belt 20 without the need for the side-standing conveyor mechanism 3.

[0018] To ensure the smooth entry of the side-standing strip-shaped packaging bags onto the grid conveyor belt 20, the second belt mechanism 31 includes a second intermediate belt roller 313. The second intermediate belt roller 313 is located between the second rear belt roller 311 and the second front belt roller 312, and is installed vertically. This means the belt section between the second intermediate belt roller 313 and the second front belt roller 312 is vertical. The advantage of this is that the strip-shaped packaging bags can maintain their side-standing posture for a longer period, thus allowing them to enter the grid conveyor belt 20 more stably.

[0019] To improve packaging efficiency, the grid conveyor belt 20 can adopt a continuous conveying mode (non-intermittent movement). In this case, the pushing mechanism 4 needs to be able to track and push the material, meaning that the pushing mechanism 4 must maintain the same moving speed and direction as the grid conveyor belt 20 during pushing. For example... Figure 3As shown, the pushing mechanism 4 includes a tracking moving seat 42 and a tracking power source 44. The pushing plate 40 and the pushing power source 41 are both mounted on the tracking moving seat 42. A guide rail 43 parallel to the conveying direction of the grid conveyor mechanism 2 is mounted on the frame 1. The tracking moving seat 42 slides on the guide rail 43, and the tracking power source 44 drives the tracking moving seat 42 to move. When the grid conveyor belt 20 uses continuous conveying, the tracking power source 44 drives the tracking moving seat 42 to move on the guide rail 43, ensuring that the moving speed and direction of the tracking moving seat 42 are the same as those of the grid conveyor belt 20 (the two are relatively stationary). In this way, the pushing power source 41 on the tracking moving seat 42 drives the pushing plate 40 to move, pushing out the packaging bags from the grid conveyor belt 20. After pushing out one row of packaging bags, the tracking power source 44 drives the tracking moving seat 42 to quickly reset, and simultaneously, the pushing power source 41 drives the pushing plate 40 to reset, preparing for the next row of packaging bags. This process repeats continuously, achieving uninterrupted pushing and improving packaging efficiency.

[0020] In order to gather the packaging bags on the closing grid platform 5, such as Figure 1 As shown, a closing and pushing mechanism 6 is provided above the closing grille platform 5, such as... Figure 5 As shown, the closing and pushing mechanism 6 includes a pushing plate 60, a pushing seat 61, a pushing power source 62, and an opening power source 63. The pushing plate 60 is movably mounted on the pushing seat 61, and the opening power source 63 is mounted on the pushing seat 61. The opening power source 63 can drive the pushing plate 60 to move up and down (including vertical swing, vertical linear movement, and diagonal linear movement). The pushing seat 61 is slidably mounted on the mounting seat 65 (the mounting seat 65 is mounted on the frame 1), and the pushing power source 62 can drive the pushing seat 61 to move. Before the packaging bag arrives at the closing grid platform 5, the opening power source 63 drives the pushing plate 60 to move upward, allowing the packaging bag to enter the closing grid platform 5. After the packaging bag enters the closing grid platform 5, the opening power source 63 drives the pushing plate 60 to move downward and to the rear of the packaging bag. Then, the pushing power source 62 drives the pushing seat 61 to move forward, so that the pushing plate 60 can push the packaging bag forward from the rear and gradually close it. Of course, the closing and pushing mechanism 6 can be a conveyor belt that forms the bottom of the closing grid platform 5. The grid groove 50 is located on the conveyor belt, and the material can be gathered by the conveyor belt.

[0021] In order to reduce the distance that the pusher plate 60 moves each time, such as Figure 5As shown, multiple push plates 60 are provided on the movable base 61. The push plates 60 are arranged back and forth along the pushing direction, and all push plates 60 are connected to the connecting rod 64. The opening power source 63 is connected to the connecting rod 64 for transmission. Driven by the opening power source 63, the connecting rod 64 can drive the multiple push plates 60 to move up and down together. Because multiple push plates 60 are provided, each time the material is pushed, only a small distance needs to be moved by the push plates 60 to achieve the pushing, ensuring stable closing and pushing.

[0022] The push plate 60 can be hinged to the movable seat 61. All the push plates 60 are hinged to the connecting rod 64. When the connecting rod 64 moves back and forth, it can drive all the push plates 60 to swing up and down.

[0023] like Figure 5 As shown, the power source 63 for opening the plates is a cylinder, which is hinged to the pusher seat 61, and the piston rod of the cylinder is hinged to the connecting rod 64. By pushing the cylinder, the connecting rod 64 can move, thereby driving all the pusher plates 60 to move.

[0024] In order to ensure that the packaging bags smoothly transition from the grid conveyor belt 20 to the closing grid platform 5, such as Figure 4 As shown, the grid groove 50 of the closing grid platform 5 has a buffer section 51 and a closing section 52. The grid grooves of the buffer section 51 are parallel to each other, while the grid grooves of the closing section 52 gradually close. The buffer section 51 of the closing grid platform 5 is close to the grid conveyor belt 20. The buffer section 51 of the closing grid platform 5 can make the packaging bag transition more smoothly from the grid conveyor belt 20 to the closing grid platform 5, preventing material blockage during the transition.
