Description

Technical Field

[0001] This utility model relates to the field of paper bag production equipment, and in particular to a conveying mechanism for a handle patch of a tote bag. Background Technology

[0002] In traditional paper bag conveying mechanisms, the width of the pallet for handle-type paper bags is fixed, making it unsuitable for paper bag handles of different sizes. This causes the bag straps of wide-handled paper bags to sag, affecting conveying stability. Furthermore, the fixed position of the existing conveyor chain means the thrust point cannot be adjusted according to the paper bag size, causing the pusher force to deviate from the bag's center. The fixed pallet only accommodates a single-size handle-type paper bag, resulting in poor production flexibility. A skewed handle leads to an unstable bag center of gravity, causing the paper bags to tilt or pile up, leading to deviation or jamming. Therefore, the following technical problems need to be solved: 1. Fixed pallet width causing bag strap sag: Paper bags with different handle widths require different support areas; 2. Inappropriate thrust point: When the chain's left and right positions are fixed, it must match the force requirements of different bag sizes; 3. Insufficient conveying stability: Sagging bag straps and deviated thrust cause paper bags to easily tilt or jam during conveying. Summary of the Invention

[0003] This utility model addresses the shortcomings of existing technologies by providing a conveying mechanism for the handle patch of a tote bag.

[0004] To solve the above-mentioned technical problems, this utility model achieves its solution through the following technical solution:

[0005] A conveying mechanism for a handle patch of a tote bag includes a frame, on which a handle support plate, a conveyor chain, and a flap are disposed in the middle. The handle support plate extends longitudinally; conveyor chains are arranged on both sides of the handle support plate, conveying the handle patch longitudinally. Push blocks for pushing the handle patch are spaced apart on the conveyor chains; the flap is disposed on one or both sides of the handle support plate in the left-right direction, and the flap is located inside the conveyor chain. The flap can be raised, lowered, or swung. The flap has a first upward state and a second downward state. In the first state, the upper surface of the flap is on the same plane as the handle support plate. In the second state, the flap is lower than the handle support plate, and the flap moves inward or flips to avoid the conveyor chain. The pallet supports the paper bag handle, and the pusher on the conveyor chain propels the paper bag forward. This structure realizes the basic conveying function of the paper bag and ensures the continuity of the paper bag in the conveying process. The flip plate can selectively rise or fall according to the different sizes of handle patches, ensuring that the bag rope will not hang below the handle pallet, regardless of whether the handle patch is small or large, so as not to affect the subsequent conveying of the handle patch, thereby improving the yield.

[0006] Preferably, the flap and the handle tray are connected by hinges, and the flap can be locked in the first state. The flaps set on one or both sides of the tray are connected by hinges, which can be adjusted according to the width of the handle of paper bags of different sizes, expand the tray area, prevent the bag rope from sagging on the left and right sides, and improve the stability and reliability of the conveying.

[0007] Preferably, the device also includes a patch tray, which is located on the left and right sides of the handle tray and has a support surface that is flush with the upper surface of the handle tray.

[0008] Preferably, the patch tray is connected to a lateral adjustment power source.

[0009] Preferably, the conveyor chain is mounted on the conveyor sprocket, which is connected to a lateral adjustment power source. The conveyor chain is positioned on both sides of the frame, allowing for adjustment of its position according to the bag size. This results in a more rational application of the pusher force to the bag, further ensuring the stability of the conveying process, and is particularly suitable for conveying paper bags of different sizes.

[0010] Preferably, the lateral adjustment power source includes an adjusting nut connected to the conveyor sprocket and a rotating screw that is threaded into the adjusting nut.

[0011] Preferably, a handle attaching device is also included, the conveying direction of which is perpendicular to the conveying direction of the handle attaching device's conveying mechanism. This vertical arrangement saves machine space.

[0012] Preferably, the patch plate on the side away from the handle device is equipped with a vertical baffle.

[0013] Preferably, the conveying mechanism for the handle patch has one or more horizontal or inclined handle trays.

[0014] This utility model, by adopting the above technical solution, has significant technical effects:

[0015] By using two different states of the flip plate, the problems of bag rope sagging and thrust offset of handle patches of different specifications are solved, thereby improving conveying efficiency;

[0016] Modular adjustment adapts to different paper bag specifications, and the lateral adjustment mechanism enables the chain / pallet spacing to quickly adapt to different patch sizes, reducing equipment modification costs. Attached Figure Description

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] A conveying mechanism for a tote bag handle patch, such as Figure 3-4 As shown, the system includes a frame 1, on which a handle support plate 2 for supporting the handle, a conveyor chain 3, and a flap 4 are arranged in the middle. The handle support plate 2 extends longitudinally; the conveyor chains 3 are arranged on both sides of the handle support plate 2, and the conveyor chains 3 convey the handle patch along the longitudinal direction. Push blocks 31 for pushing the handle patch are arranged at intervals on the conveyor chains 3; the flap 4 is arranged on one or both sides of the handle support plate 2 in the left and right direction. The flap 4 is located inside the conveyor chain 3. The flap 4 can be raised, lowered, or swung. The flap 4 has a first state of rising and a second state of falling. In the first state, the upper surface of the flap 4 is on the same plane as the handle support plate 2. In the second state, the flap 4 is lower than the handle support plate 2 and the flap 4 avoids the conveyor chain 3 by flipping or moving inward.

[0025] In one way, the flap 4 is positioned to allow for the handrail support 2 to move. The flap 4 is movably connected to the handrail support 2 via a hinge 41, and the flap 4 can be locked in its first state. Locking ensures stable support after the flap is unfolded, preventing swaying during transport. In another way, the flap 4 can move horizontally and vertically. When the handrail support 2 is not required to move, the flap moves vertically downwards and then horizontally inwards to reach below the handrail support 2, thus allowing for the transport of the handrail patch.

[0026] It also includes a patch plate 5, which is located on the left and right sides of the handle plate 2. The patch plate 5 has a support surface that is flush with the upper surface of the handle plate 2.

[0027] The patch tray 5 is connected to a lateral adjustment power source 33. A conveyor chain 3 is mounted on a conveyor sprocket 32, which is also connected to the lateral adjustment power source 33. The patch tray 5 and the conveyor chain 3 can have independent lateral adjustment power sources 33, or they can share a common lateral adjustment power source 33. As one possible structure for the lateral adjustment power source 33, it includes an adjusting nut 331 connected to the conveyor sprocket 32, and a rotating screw 332 threadedly engaged with the adjusting nut 331. A motor or other alternative drive device drives the rotating screw 332 to rotate, causing the adjusting nut 331 to move laterally in a predetermined manner, thus achieving the adjustment purpose.

[0028] like Figure 1-2 As shown, it also includes a handle attaching device 6, the conveying direction of which is perpendicular to the conveying direction of the handle attaching device conveying mechanism.

[0029] A vertical baffle 51 is provided on the side of the patch holder 5 away from the handle device 6. The vertical baffle 51 can block the handle patch after it enters the handle patch conveying mechanism laterally, thus limiting its lateral movement.

[0030] The conveying mechanism for the hand-held patch has one or more horizontal or inclined hand-held trays 2.

[0031] In practical applications, the first step is to determine whether the flap 4 needs to be unfolded based on the width of the handle of the paper bag to be conveyed. If so, the flap 4 rises to the first state, coplanar with the handle support plate 2; if not, the flap 4 falls to the second state, moving inward to avoid the conveyed handle patch, and the conveyor chain 3 is then conveyed.

[0032] If the paper bag handle is wide, unfold one or both sides of the handle support plate 2. As one implementation, the flap 4 is connected by a hinge, so that the flap 4 and the handle support plate 2 form a larger support area, and the paper bag handle is placed on the handle support plate and the unfolded flap 4 to prevent the bag strap from sagging.

[0033] Then, when changing the patch specifications according to the size of the paper bag, the spacing of the patch tray 5 and the position of the chain 3 are adjusted synchronously by rotating the lead screw 332. By adjusting the position of the conveyor chain 3 on both sides of the frame 1, the push blocks 31 spaced apart on the conveyor chain 3 can act on the bag body at appropriate positions, pushing the paper bag forward. When conveying paper bags of different specifications, the above adjustment process is repeated to achieve stable conveying.

[0034] In this way, the paper bag conveying mechanism of this utility model can adapt to paper bags of different specifications, ensuring the stability and efficiency of the conveying process.

[0035] In the description of this utility model, it should be understood that the terms "center," "length," "width," "thickness," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.
