Description

Technical Field

[0001] This invention belongs to the field of packaging bag manufacturing technology, and in particular relates to a handle strip feeding mechanism and a handle strip feeding method. Background Technology

[0002] A bag-making machine is a specialized piece of equipment used to produce packaging bags made of materials such as plastic, non-woven fabric, and paper. It is primarily used in the clothing, food, and gift industries to meet their packaging needs. For example, a bag-making machine can produce shopping bags, garment bags, food bags, and other similar products.

[0003] Generally, during the production of packaging bags by a bag-making machine, handles, or pulls, need to be set at the edge of the bag opening. When the bag-making machine processes the handles on the bag blank, it usually needs to gradually unfold the handle strip roll on the feeding rack and send it to the handle forming mechanism. Then, the handle forming mechanism cuts the entire handle strip into pieces and installs them on the bag body.

[0004] However, in the existing technology of the handle conveyor mechanism, when the handle strip roll is gradually unfolded and conveyed, after one handle strip roll is conveyed, the operator needs to assemble a new handle strip roll on the feeding rack and then move the front end of the new handle strip roll to the next process. Since the process of reinstalling a new handle strip roll on the feeding rack consumes a lot of time, it reduces the conveying efficiency of the handle strip and thus greatly reduces the production efficiency of packaging bags. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the existing technology of the handle conveying mechanism. When the handle strip is gradually unfolded and conveyed, after one handle strip is conveyed, the operator needs to assemble a new handle strip onto the feeding rack and then move the front end of the new handle strip to the next process. However, this process of installing a new handle strip onto the feeding rack consumes a lot of time, which reduces the conveying efficiency of the handle strip and thus greatly reduces the production efficiency of packaging bags.

[0006] To solve the above-mentioned technical problems, the present invention discloses a handle bar feeding mechanism, including a frame and a feeding assembly disposed on the frame. The feeding assembly includes a feeding chamber that can simultaneously accommodate multiple handle bar rolls. Multiple discharge ports are arranged side by side on one side of the feeding chamber. Multiple handle bar rolls are placed in the feeding chamber, and the front end of the handle bar on each handle bar roll is aligned with the corresponding discharge port.

[0007] Furthermore, the relative positions of the feeding chamber and the feed port of the next process in the arrangement direction of multiple discharge ports are adjustable, and any discharge port can be aligned with the feed port to input the front end of the handle bar on the corresponding handle bar roll into the feed port.

[0008] Using the above technical solution, this handle conveying mechanism places multiple handle rolls in the feeding bin during operation, aligning the front end of each handle roll with its corresponding outlet. Then, the position of the feeding bin is adjusted along the arrangement direction to align one outlet with the inlet, thus conveying the front end of one handle roll to the next process via both outlet and inlet. After one handle roll is conveyed, the position of the feeding bin is adjusted again along the arrangement direction to align another outlet with the inlet, and the front end of another handle roll is conveyed to the next process via another outlet and inlet. This process is repeated, changing the handle rolls as needed. During this process, it is unnecessary for staff to replenish the feeding bin with new handle rolls after each roll is conveyed, reducing the time spent replenishing handle rolls and thus improving the conveying efficiency of handles and the production efficiency of packaging bags.

[0009] In addition, when multiple hand-operated strip rolls are almost finished being conveyed, for example, when the last hand-operated strip roll is being conveyed through the corresponding discharge port, the operator can replenish the hand-operated strip rolls in the discharge chamber at the position corresponding to the other inlets. After the last hand-operated strip roll is conveyed, the position of the discharge chamber can be adjusted, and then other hand-operated strip rolls can be conveyed without affecting the conveying efficiency of the hand-operated strips.

[0010] Furthermore, embodiments of the present invention also disclose a hand-operated strip conveying mechanism, wherein the feeding assembly further includes a position adjustment component mounted on the frame, and the feeding chamber is movably disposed on the position adjustment component along the arrangement direction so that an outlet is aligned with an inlet.

[0011] Using the above technical solution, after a handle bar roll is completely conveyed, the feeding chamber moves along the arrangement direction on the position adjustment component, so that one discharge port is aligned with the feed port, thereby continuing to convey another handle bar; during this process, the feeding chamber is movably set on the position adjustment component, so as to facilitate the adjustment of the position of the feeding chamber.

[0012] Furthermore, embodiments of the present invention also disclose a hand-operated strip conveying mechanism, wherein the position adjustment component includes a guide portion and a drive component fixedly mounted on the frame, the guide portion extends along the arrangement direction, and the discharge chamber is movably disposed on the guide portion along the arrangement direction, the drive component is pultrusively connected to the discharge chamber and drives the discharge chamber to move relative to the guide portion; wherein the drive component drives the discharge chamber to move along the guide portion so that an outlet is aligned with an inlet.

[0013] Using the above technical solution, after a roll of handle bar material is conveyed, the drive unit drives the unloading chamber to move rapidly along the arrangement direction on the guide section, so that one discharge port is aligned with the inlet, thereby continuing to convey another handle bar. During this process, the drive unit drives the unloading chamber to move along the arrangement direction on the moving section, thereby changing the position of the unloading chamber, saving manpower and reducing the time spent changing the position of the unloading chamber, making this handle bar conveying mechanism more automated.

[0014] Furthermore, embodiments of the present invention also disclose a hand-operated strip conveying mechanism, wherein the feeding chamber includes a plurality of storage cavities arranged side by side along the arrangement direction, each storage cavity being used to store a hand-operated strip roll.

[0015] Each hand-operated strip roll is rotatably arranged in a corresponding storage cavity, with each roll shaft parallel to the arrangement direction; and a discharge roller assembly is also provided in each storage cavity near the discharge port, through which the front end of the hand-operated strip roll enters the discharge port.

[0016] By adopting the above technical solution, multiple storage cavities are set to separate multiple hand-operated strip rolls, reducing the risk of interference between multiple hand-operated strip rolls during the individual conveying process; each hand-operated strip roll can be rotatably set in a corresponding storage cavity around the roll shaft, so that each hand-operated strip roll gradually unfolds and is conveyed during the conveying process, with no interference between the front and rear ends.

[0017] In addition, since the front end of each handle bar enters the discharge port via the discharge roller assembly, it is supported when the handle bar enters the feed port, reducing the risk of the handle bar shifting position when it enters the feed port from the discharge port.

[0018] Furthermore, embodiments of the present invention also disclose a hand-held strip conveying mechanism, wherein the discharge roller group includes at least one support roller arranged sequentially along the conveying direction of the hand-held strip roll, and the support rollers are all rotatably connected to the inner wall of the storage cavity; and each storage cavity is also provided with at least one limiting member to restrict the axial movement of the corresponding hand-held strip roll in the storage cavity.

[0019] By adopting the above technical solution, and by setting the support rollers to be rotatably connected to the inner wall of the storage cavity, the friction between the handle bar and the support rollers is reduced when the handle bar is supported by the support rollers and is continuously conveyed, making the handle bar smoother when it is conveyed.

[0020] In addition, by providing at least one limiting member in each storage cavity, the axial movement of the corresponding handle strip roll in the storage cavity is restricted, so that the position of the handle strip roll will not shift during the gradual unfolding and conveying process.

[0021] Furthermore, embodiments of the present invention also disclose a handle conveying mechanism, wherein the position adjustment component further includes a plurality of detection units arranged at intervals on the guide portion in the arrangement direction; wherein the plurality of detection units correspond one-to-one with a plurality of storage cavities and detect the position of each storage cavity relative to the feed inlet.

[0022] By adopting the above technical solution, multiple detection units are spaced apart on the guide section, and each detection unit corresponds to a multiple storage cavity to detect the position of each storage cavity relative to the feed inlet. This ensures that after a hand-operated strip roll is completely conveyed, the position of the unloading chamber is changed by moving along the arrangement direction on the position adjustment component. The detection unit then detects the position of the corresponding storage cavity, thereby ensuring that the feed inlet and the discharge outlet can be accurately aligned. This ensures that the hand-operated strip roll can be reliably and gradually unfolded and conveyed when the feed inlet and the discharge outlet are aligned.

[0023] Furthermore, embodiments of the present invention also disclose a hand-operated strip conveying mechanism, wherein a connecting component is provided on the upstream side of the feed inlet in the conveying direction of the hand-operated strip roll.

[0024] In this process, the rear end of the handle strip of a handle strip roll corresponding to an outlet aligned with the inlet enters the joining assembly through the outlet. The discharge chamber moves along the arrangement direction to change its position, moving the other outlet to the front end of the handle strip of another handle strip roll aligned with the inlet and corresponding to the other outlet, which then enters the joining assembly. The joining assembly joins the rear end of the handle strip of one handle strip roll with the front end of the handle strip of another handle strip roll.

[0025] Using the above technical solution, after one roll of handle strip is conveyed, there is no need to manually pull the front end of another roll of handle strip into the feed inlet before conveying the other roll. Instead, the material discharge chamber is moved along the arrangement direction to change its position, so that the other discharge port is aligned with the feed inlet and the front end of the handle strip of the corresponding roll enters the joining assembly. The joining assembly then joins the rear end of the handle strip of one roll with the front end of the handle strip of another roll, thereby achieving continuous conveying of handle strips. This reduces labor costs and the time lost from manual material pulling, making the conveying mechanism more efficient when conveying handle strip rolls, thus improving the production efficiency of packaging bags.

[0026] Furthermore, embodiments of the present invention also disclose a handle conveying mechanism, wherein the joining assembly includes a support platform and a pressing component mounted on a frame.

[0027] The pressing component and the support platform are arranged opposite each other in the pressing direction. The rear end of the handle strip of one handle strip roll and the front end of the handle strip of another handle strip roll are stacked on the support platform. The pressing head of the pressing component moves along the pressing direction to press the rear end of one handle strip roll and the front end of another handle strip roll together.

[0028] By adopting the above technical solution, the rear end of one handle strip coil and the front end of another handle strip coil are stacked on the support platform, thereby increasing the contact area between the rear end of one handle strip coil and the front end of another handle strip coil. Then, the rear end of one handle strip coil and the front end of another handle strip coil are pressed together by a pressing component, thereby enabling the rear end of one handle strip coil and the front end of another handle strip coil to be more firmly connected together, improving the connection strength between the two and reducing the risk of breakage at the connection point during continuous handling strip feeding.

[0029] Furthermore, embodiments of the present invention also disclose a hand-operated bar conveying mechanism, wherein, in the conveying direction, a leveling assembly is installed on the discharge hopper, which is located downstream of multiple discharge ports in the conveying direction.

[0030] The leveling assembly includes multiple leveling components arranged side by side and corresponding to multiple discharge ports. When each handle bar roll is conveyed along the conveying direction, the corresponding leveling component is used to level the handle bar.

[0031] By adopting the above technical solution, when each handle strip roll is conveyed along the conveying direction, the corresponding flattening component is used to flatten the handle strip, so that the handle strip is wrinkle-free or folded when it enters the joining assembly. On the one hand, this avoids the risk that when the rear end of the handle strip of one handle strip roll is stacked on the support platform with the front end of the handle strip of another handle strip roll, the contact area between the two is small or misaligned due to wrinkles or folds, resulting in weak connection strength or failure to join. On the other hand, it avoids the risk that after the handle strip enters the feed port and is cut in the next process and installed on the bag body, the packaging bag will be unsightly due to wrinkles or folds in the handle strip.

[0032] Furthermore, embodiments of the present invention also disclose a handle bar conveying mechanism, wherein each flattening component includes at least one pair of pressure rollers arranged sequentially in the conveying direction, each pair of pressure rollers being arranged opposite to each other along the height direction of the frame and rotatably connected to the unloading chamber, and when each handle bar roll is conveyed along the conveying direction, the handle bar is respectively connected to the corresponding pressure rollers on both sides in the height direction of the frame.

[0033] By adopting the above technical solution, the handle strip is connected to the corresponding pressure rollers on both sides of the frame in the height direction. This ensures that the handle strip is flattened by each pair of pressure rollers during the conveying process, without wrinkles or folds. Furthermore, since each pair of pressure rollers is arranged opposite to each other along the height direction of the frame and rotatably connected to the feeding chamber, the friction between the handle strip and each pair of pressure rollers is reduced during the conveying process, allowing the handle strip to pass smoothly through each pair of pressure rollers.

[0034] Furthermore, embodiments of the present invention also disclose a handle conveying mechanism, wherein the joining assembly further includes a belt end detection member disposed on the upstream side of the pressing member in the conveying direction of the handle roll.

[0035] Among them, the end detection component is located on the same side as the pressing component in the pressing direction. When the end detection component detects that the rear end of the current handle strip roll has entered the support platform, the feeding chamber moves along the arrangement direction to change its position, and moves the corresponding discharge port of another handle strip roll to be aligned with the feeding port.

[0036] By adopting the above technical solution, by setting up an end detection component to detect the rear end of the current handle bar roll entering the support platform, the corresponding outlet of the other handle bar roll can be moved to align with the inlet. After the front end of the other handle bar roll enters the support platform, the rear end of one handle bar roll and the front end of the other handle bar roll can be accurately stacked on the support platform, thus ensuring that the rear end of one handle bar roll and the front end of the other handle bar roll are accurately fixed together. This avoids the risk of the rear end of the first handle bar roll drooping down after the rear end of the current handle bar roll has not yet entered the support platform, causing deviations in the subsequent handle bar conveying.

[0037] Furthermore, embodiments of the present invention also disclose a handle conveying mechanism, which further includes a conveying component located downstream of the joining component in the conveying direction; wherein, the handle of a handle roll corresponding to an outlet aligned with the inlet passes through the joining component and the conveying component in sequence before entering the inlet.

[0038] By adopting the above technical solution, since the conveying component is located downstream of the joining component in the conveying direction, when conveying the handle strip, the handle strip of one handle strip roll corresponding to one of the discharge ports aligned with the feed port passes through the joining component and the conveying component in sequence before entering the feed port. The conveying component can continuously convey the handle strip. When the rear end of one handle strip roll enters the support platform, the front end of another handle strip roll enters the support platform, and the two are pressed and fixed by the pressing component, the conveying component continues to convey another handle strip roll. This process is repeated, and the handle strip can be conveyed without interruption, improving the conveying efficiency of the handle strip and further improving the production efficiency of the packaging bag.

[0039] Furthermore, embodiments of the present invention also disclose a hand-held strip conveying mechanism, wherein the conveying assembly includes a feeding component and a storage component sequentially mounted on the frame along the conveying direction.

[0040] The handle bar is conveyed to the feed inlet after passing through the joining assembly, feeding component, and storage component in sequence along the conveying direction. The feeding component continuously conveys the handle bar along the conveying direction.

[0041] Using the above technical solution, when a handle strip roll is gradually unfolded and conveyed, the handle strip passes sequentially through the joining component, the feeding component, and the storage component along the conveying direction before being conveyed to the inlet. At this time, the feeding component continuously conveys the handle strip along the conveying direction. When the rear end of one handle strip roll enters the joining component and the front end of another handle strip roll enters the joining component, the joining component joins the rear end of one handle strip roll with the front end of another handle strip roll. At this time, the feeding component stops conveying the handle strip along the conveying direction, while the handle strip in the storage component is continued to be conveyed by the conveying device of the next process. During this process, the supply of handle strips is uninterrupted, thereby ensuring the bag making efficiency of the packaging bag.

[0042] Furthermore, embodiments of the present invention also disclose a hand-operated strip conveying mechanism, wherein the feeding component includes a feeding drive component, and feeding rollers and limiting rollers arranged side by side and rotatably mounted on the frame; the storage component includes a first storage roller group and a second storage roller group that are sequentially spaced along the height direction of the frame.

[0043] The first storage roller group includes a plurality of first storage rollers rotatably mounted on the frame and arranged side by side along the conveying direction; the second storage roller group includes a roller group mounting frame movable along the height direction of the frame, and a plurality of second storage rollers arranged side by side along the conveying direction and spaced apart from each other on the roller group mounting frame.

[0044] Furthermore, multiple first storage rollers correspond one-to-one with multiple second storage rollers. When the handle bar is conveyed along the conveying direction, the feeding roller and the limiting roller clamp the handle bar. The feeding drive component drives the feeding roller to rotate and continuously convey the handle bar. The handle bar passes through the storage roller pairs composed of the corresponding first storage rollers and second storage rollers in sequence and enters the feed port. Moreover, the position of the roller assembly mounting frame relative to the height direction of the machine frame is limited by its own weight and the tension of the handle bar.

[0045] Using the above technical solution, when the handle strip is continuously conveyed by the feeding component, the feeding roller and the limiting roller clamp the handle strip, and the feeding drive component drives the feeding roller to rotate and continuously convey the handle strip, so that the handle strip will not shift in position during the conveying process because it is clamped. When the rear end of one handle strip roll enters the joining component and the front end of another handle strip roll enters the joining component, the joining component joins the rear end of one handle strip roll with the front end of another handle strip roll, and the feeding drive component stops driving the feeding roller to rotate and convey the handle strip. At this time, the conveying device of the next process continues to convey the handle strip, thereby pulling the roller group mounting frame to move along the height direction toward the first storage roller group, so that the handle strip between the corresponding first storage roller and second storage roller pairs can be continuously conveyed, ensuring uninterrupted conveying of the handle strip, and there is no need to stop conveying the handle strip when changing the handle strip roll, which greatly improves the conveying efficiency of the handle strip.

[0046] In addition, when the height of the roller assembly mounting frame is too high, the feeding drive component drives the feeding roller to rotate rapidly to increase the conveying speed of the handle strip, so that the roller assembly mounting frame can move downward along the height direction under its own weight, thereby storing a certain length of handle strip.

[0047] Furthermore, embodiments of the present invention also disclose a handle conveying mechanism, wherein the conveying assembly further includes a first detection component and a second detection component spaced apart on the frame along the height direction of the frame.

[0048] In the height direction of the frame, the roller assembly mounting frame is located between the first detection component and the second detection component, and the first detection component and the second detection component are used to detect the position of the roller assembly mounting frame in the height direction of the frame.

[0049] Using the above technical solution, when the rear end of one hand-twisted strip roll enters the joining assembly and the front end of another hand-twisted strip roll enters the joining assembly, the joining assembly joins the rear end of one hand-twisted strip roll with the front end of the other hand-twisted strip roll. At this time, the feeding drive component stops driving the feeding roller to rotate and convey the hand-twisted strip. Meanwhile, the conveying device of the next process continues to convey the hand-twisted strip, thereby pulling the roller assembly frame to move along the height direction towards the first storage roller assembly, continuously conveying the hand-twisted strip between the corresponding storage roller pairs composed of the first and second storage rollers. After the rear end of one hand-twisted strip roll is joined with the front end of another hand-twisted strip roll... When the first detection component detects that the height of the roller assembly mounting frame is too high, the feeding drive component drives the feeding roller to rotate rapidly to increase the conveying speed of the handle strip, thereby causing the roller assembly mounting frame to move downward along the height direction under its own weight. After the second detection component detects the roller assembly mounting frame, it adjusts the rotation speed of the feeding roller driven by the feeding drive component to maintain the same speed as the conveying device in the next process, and the roller assembly mounting frame stops moving. This ensures that after the handle strip roll is replaced, the first and second storage roller sets can store a certain length of handle strip in real time, ensuring that the handle strip can be continuously conveyed during the process of changing the handle strip roll.

[0050] The present invention also discloses a method for feeding a handle strip, which utilizes the aforementioned handle strip feeding mechanism and includes the following steps:

[0051] Multiple hand-operated strip rolls are installed in the feeding chamber, with each hand-operated strip roll corresponding to one of the multiple discharge ports.

[0052] The front end of a handle strip roll corresponding to an outlet aligned with the feed port of the next process is conveyed to the next process after passing through the joining component and the conveying component in sequence along the conveying direction. The conveying component continuously conveys the handle strips until the rear end of the handle bag of a handle strip roll passes through the corresponding outlet and enters the joining component.

[0053] The rear end of the handle bag of a handle strip roll passes through a corresponding discharge port. The position adjustment component drives the feeding chamber to move along the arrangement direction to change its position, and moves the other discharge port to be aligned with the inlet port. The front end of the handle strip of another handle strip roll corresponding to the other discharge port enters the joining component.

[0054] By adopting the above technical solution, when the conveying component continuously conveys one corresponding handle roll as the multiple handle rolls are gradually unfolded, the rear end of the handle bag of one handle roll passes through the corresponding discharge port. The position adjustment component drives the feeding chamber to move along the arrangement direction to change its position, moving the other discharge port to be aligned with the inlet port. The front end of the handle of the other handle roll corresponding to the other discharge port enters the joining component, thereby joining the two together. There is no need for manual pulling of the front end of the other handle roll through the discharge port, joining component, and transmission component to the inlet of the next process. This further reduces the time lost by manual material pulling and lowers labor costs. This handle conveying mechanism has higher conveying efficiency when conveying handle rolls, thereby improving the production efficiency of packaging bags.

[0055] Furthermore, embodiments of the present invention also disclose a method for feeding handle strips, wherein during the joining process of the joining components, the conveying component continuously feeds the handle strips.

[0056] By adopting the above technical solution, since the conveying component continuously transports the handle strip during the joining process of the joining component, the transport of the handle strip is uninterrupted, which improves the transport efficiency of the handle strip and further improves the production efficiency of the packaging bag.

[0085] As described in the background section, in the existing technology, when the handle strip conveying mechanism gradually unfolds and conveys the handle strip rolls, after one handle strip roll is conveyed, the operator needs to reassemble a new handle strip roll onto the feeding rack and then move the front end of the new handle strip roll to the next process. However, since reassembling a new handle strip roll onto the feeding rack consumes a lot of time, it reduces the conveying efficiency of the handle strips, which in turn reduces the production efficiency of the packaging bags.

[0086] To solve the above problems, the present invention provides a handle bar feeding mechanism, including a frame and a feeding assembly disposed on the frame. The feeding assembly includes a feeding chamber that can simultaneously accommodate multiple handle bar rolls. Multiple discharge ports are arranged side by side on one side of the feeding chamber. Multiple handle bar rolls are placed in the feeding chamber, and the front end of the handle bar on each handle bar roll is aligned with the corresponding discharge port. This type of handle conveyor mechanism, during operation, transports the front end of a handle roll from the feeding bin to the next process via an outlet and an inlet. Once one handle roll is transported, the feeding bin is simply adjusted in the alignment direction to align another outlet with the inlet, and then the front end of another handle roll is transported to the next process via another outlet and inlet. This process is repeated, changing the handle rolls as needed. During this process, there is no need for workers to re-place and install handle rolls in the feeding bin after each transport, reducing time waste and thus improving the conveying efficiency of handles and the production efficiency of packaging bags.

[0087] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0088] like Figure 1 and Figure 2 As shown, this embodiment provides a handle bar feeding mechanism, including a frame 1 and a feeding assembly 2 disposed on the frame 1. The feeding assembly 2 includes a feeding chamber 20 capable of simultaneously accommodating multiple handle bar rolls 10. Multiple discharge ports 22 are arranged side-by-side on one side of the feeding chamber 20 (see [link to documentation]). Figure 3 Multiple handle strip rolls 10 are placed in the feeding chamber 20, with the front end of the handle strip on each handle strip roll 10 aligned with the corresponding discharge port 22. It should be understood that the feeding chamber 20 can hold 2, 4, or 5 handle strip rolls 10, and the number of discharge ports 22 can be set to 2, 4, or 5, etc., respectively. This embodiment does not impose a unique limitation.

[0089] Specifically, the relative positions of the discharge chamber 20 and the feed port of the next process in the arrangement direction L of the multiple discharge ports 22 are adjustable, and any discharge port 22 can be aligned with the feed port to input the front end of the handle strip on the corresponding handle strip roll 10 into the feed port.

[0090] More specifically, please refer to the following for the working operation of this hand-operated bar conveyor mechanism. Figure 2 Multiple handle strip rolls 10 are placed in the feeding chamber 20, and the front end of each handle strip roll 10 is aligned with the corresponding discharge port 22. Then, the position of the feeding chamber 20 is adjusted along the arrangement direction L to align one discharge port 22 with the inlet, so that the front end of one handle strip roll 10 in the feeding chamber 20 is conveyed to the next process through one discharge port 22 and the inlet. When one handle strip roll 10 is conveyed, the position of the feeding chamber 20 is adjusted along the arrangement direction L to align another discharge port 22 with the inlet, and then the front end of another handle strip roll 10 is conveyed to the next process through another discharge port 22 and the inlet. This process of changing handle strip rolls 10 is repeated. In this process, it is not necessary for the staff to put and install handle strip rolls 10 back into the feeding chamber 20 after each hand strip roll 10 is conveyed, which reduces time loss and improves the conveying efficiency of handle strips and the production efficiency of packaging bags.

[0091] Furthermore, when multiple hand-operated strip rolls 10 are almost finished being conveyed, for example, when the last hand-operated strip roll 10 is being conveyed through the corresponding discharge port 22, the operator can replenish the hand-operated strip roll 10 in the discharge chamber 20 at the position corresponding to the other inlets. Thus, after the last hand-operated strip roll 10 is conveyed, the position of the discharge chamber 20 can be adjusted, and other hand-operated strip rolls 10 can be conveyed without affecting the conveying efficiency of the hand-operated strips.

[0092] It should be further noted that in some embodiments, the arrangement direction L can be the width direction of the feeding chamber 20, or of course, the height direction, length direction, etc. When adjusting the position of the feed inlet, the feeding chamber 20 or the feed inlet of the next process can be shifted to align any one of the discharge ports 22 with the feed inlet. Of course, in another embodiment, multiple discharge ports 22 can also be arranged in a circular parallel arrangement on the feeding chamber 20. By rotating the feeding chamber 20, any one of the discharge ports 22 can be aligned with the feed inlet. In this case, the arrangement direction L is the rotation direction of the feeding chamber 20. This embodiment is not limited to a single one, and those skilled in the art can design according to their own needs.

[0093] In addition, the next step can be the handle installation mechanism. After the handle is transported to the handle installation mechanism, it is cut one by one and installed onto the bag body of the packaging bag.

[0094] The following explains how the discharge chamber 20 moves in the arrangement direction L.

[0095] In one implementation, such as Figure 1 and Figure 3 As shown, the feeding assembly 2 also includes a position adjustment component 21 mounted on the frame 1. The feeding chamber 20 is movably disposed on the position adjustment component 21 along the arrangement direction L so that a discharge port 22 is aligned with the feed port.

[0096] Specifically, after a handle bar roll 10 is completely conveyed, the feed chamber 20 moves along the arrangement direction L on the position adjustment component 21, so that one discharge port 22 is aligned with the feed port, thereby continuing to convey another handle bar; during this process, the feed chamber 20 is positioned on the position adjustment component 21 by moving along the arrangement direction L, thereby facilitating the adjustment of the position of the feed chamber 20.

[0097] More specifically, the structure and arrangement of the position adjustment component 21 are not limited, and the following is an example.

[0098] In one implementation, such as Figure 3 As shown, the position adjustment component 21 includes a guide portion 210 and a drive component 211 fixedly mounted on the frame 1. The guide portion 210 extends along the arrangement direction L, and the discharge chamber 20 is movably disposed on the guide portion 210 along the arrangement direction L. The drive component 211 is connected to the discharge chamber 20 and drives the discharge chamber 20 to move relative to the guide portion 210. The drive component 211 drives the discharge chamber 20 to move along the guide portion 210 so that one discharge port 22 is aligned with the inlet port.

[0099] Specifically, after a roll of handle bar 10 is conveyed, the drive unit 211 drives the unloading chamber 20 to move rapidly along the arrangement direction L on the guide part 210, so that one discharge port 22 is aligned with the inlet, thereby continuing to convey another handle bar; during this process, the drive unit 211 drives the unloading chamber 20 to move along the arrangement direction L on the moving part, thereby changing the position of the unloading chamber 20, saving manpower and reducing the time for changing the position of the unloading chamber 20, making this handle bar conveying mechanism more automated.

[0100] More specifically, the structure and configuration of the guide unit 210 are not limited, and the following is an example.

[0101] In one embodiment, the guide part 210 is configured as a base fixedly installed on the frame 1, and a pair of guide rails extending along the arrangement direction L are provided on the side of the base near the discharge chamber 20. The pair of guide rails are arranged side by side and spaced apart from each other. Guide grooves corresponding to and adapted to the pair of guide rails are provided on the discharge chamber 20, so that the discharge chamber 20 can be moved along the arrangement direction L and disposed on the guide part 210.

[0102] Of course, it should be understood that the guide 210 can also be configured as a connecting seat fixedly installed on the frame 1, and a pair of sliding grooves extending along the arrangement direction L are provided on the side of the connecting seat near the discharge chamber 20. The pair of sliding grooves are arranged side by side and spaced apart from each other. A slider 504 corresponding to and adapted to the pair of sliding grooves is provided on the discharge chamber 20, so that the discharge chamber 20 can be moved along the arrangement direction L and positioned on the guide 210.

[0103] More specifically, the structure and configuration of the driver 211 are not limited; the following is an example.

[0104] In one embodiment, the drive component 211 is configured as a linear motor fixedly mounted on the guide portion 210, and the drive end of the linear motor is connected to the feeding chamber 20 for transmission. The linear motor drives the feeding chamber 20 to move along the arrangement direction L on the guide portion 210. Of course, it should be understood that the drive component 211 can also be directly fixed to the frame 1 to drive the feeding chamber 20 to move.

[0105] In another embodiment, the drive member 211 is configured to include an electric telescopic push rod fixedly mounted on the guide portion 210, and the drive end of the electric telescopic push rod is connected to the discharge chamber 20 in a transmission manner, thereby driving the discharge chamber 20 to move along the arrangement direction L on the guide portion 210 by the electric telescopic push rod.

[0106] Furthermore, to ensure that each hand-operated strip roll 10 does not interfere with other adjacent hand-operated strip rolls 10 during the conveying process; in one embodiment, such as Figure 2 and Figure 3 As shown, the feeding chamber 20 includes multiple storage cavities 200 arranged side by side along the arrangement direction L. Each storage cavity 200 is used to store one hand-held strip roll 10. Thus, by setting multiple storage cavities 200, multiple hand-held strip rolls 10 are separated, avoiding the risk of interference between multiple hand-held strip rolls 10 during the process of conveying them one by one.

[0107] Specifically, each handle bar roll 10 is rotatably disposed in a corresponding storage cavity 200 around a roll shaft 201, and the roll shaft 201 of each handle bar roll 10 is parallel to the arrangement direction L; thus, each handle bar roll 10 is gradually unfolded and conveyed during the conveying process, with no interference between the front and rear ends.

[0108] More specifically, each storage chamber 200 is equipped with a discharge roller assembly near the discharge port 22. The front end of the handle bar roll 10 enters the discharge port 22 via the discharge roller assembly. This supports the handle bar when it enters the feed port, reducing the risk of the handle bar shifting position when it enters the feed port from the discharge port 22.

[0109] It should be noted that each handle strip roll 10 is rotatably disposed in a corresponding storage cavity 200 around the roll shaft 201, that is: the roll shaft 201 is fixedly installed in the storage cavity 200, and the handle strip roll 10 is sleeved on the roll shaft 201 and rotatably connected to the roll shaft 201.

[0110] More specifically, the structure and arrangement of the discharge roller assembly are not limited; examples are provided below.

[0111] In one implementation, such as Figure 2 As shown, the discharge roller assembly includes at least one support roller 202 arranged sequentially along the conveying direction of the handle strip roll 10, and all support rollers 202 are rotatably connected to the inner wall of the storage cavity 200. Since the support rollers 202 are rotatably connected to the inner wall of the storage cavity 200, the friction between the handle strip and the support rollers 202 is reduced when the handle strip is supported by the support rollers 202 and is continuously conveyed, making the conveying of the handle strip smoother. It should be understood that the number of support rollers 202 can be one, two, four, etc., and this embodiment does not impose a displacement limitation.

[0112] More specifically, each storage cavity 200 is also provided with at least one limiting member 203 to restrict the axial movement of the corresponding handle strip roll 10 within the storage cavity 200, so that the position of the handle strip roll 10 will not shift during the conveying process without gradually unfolding. It should be understood that each storage cavity 200 may be provided with one, two, or three limiting members 203, etc., and this embodiment does not make a unique limitation.

[0113] Furthermore, when the dimensions of the handle bar roll 10 change in its axial direction, the number of limiting members 203 can be increased or decreased to accommodate handle bar rolls 10 of different sizes, thus making this handle bar conveying mechanism more versatile.

[0114] More specifically, the structure and arrangement of the limiting component 203 are not limited, and the following is an example.

[0115] In one embodiment, the limiting member 203 includes a pair of limiting plates arranged opposite to each other in the arrangement direction L. In the height direction of the feeding chamber 20, one end of each limiting plate is fixedly installed on the top of the corresponding side of the corresponding storage cavity 200, and the other end extends away from the storage cavity 200 along the height direction of the feeding chamber 20, thereby limiting the hand-held strip material roll 10 in its axial direction after it is installed on the material roll shaft 201.

[0116] In another embodiment, the limiting member 203 includes a pair of limiting discs arranged opposite each other in the arrangement direction L. The pair of limiting discs correspond one-to-one with the two ends of the corresponding material roll 201 in the arrangement direction L. Each limiting disc is fixedly sleeved on one end of the corresponding material roll 201, thereby limiting the handle strip material roll 10 in its axial direction after it is installed on the material roll 201.

[0117] Furthermore, to ensure that each storage chamber 200 is accurately aligned with the feed inlet after position adjustment, in one embodiment, such as... Figure 3 As shown, the position adjustment component 21 also includes a plurality of detection units 212 spaced apart on the guide portion 210 along the arrangement direction L; wherein, the plurality of detection units 212 correspond one-to-one with the plurality of storage cavities 200 and detect the position of each storage cavity 200 relative to the feed inlet; thereby, when a handle strip roll 10 is completely conveyed, after the discharge chamber 20 moves along the arrangement direction L on the position adjustment component 21 to change its position, the detection units 212 detect the position of the corresponding storage cavity 200, thereby ensuring that the feed inlet and discharge outlet 22 can be accurately aligned, avoiding the problem that the handle strip roll 10 cannot be gradually unfolded and conveyed if the feed inlet and discharge outlet 22 are not aligned. It should be understood that the number of the plurality of detection units 212 is not limited, for example, it can be 2, 3, 5, etc., and this embodiment does not make a unique limitation.

[0118] Specifically, the structure and arrangement of the detection unit 212 are not limited. For example, it can be a photoelectric sensor, an ultrasonic sensor, etc. This embodiment does not limit it to a single type.

[0119] Furthermore, to further enhance the automation of this hand-operated bar conveying mechanism; in one embodiment, such as Figure 1 and Figure 4 As shown, in the conveying direction of the hand-held strip roll 10, a connecting component 3 is also provided on the upstream side of the feed inlet, and the connecting component 3 is installed on the frame 1.

[0120] Specifically, the rear end of the handle strip of a handle strip roll 10 corresponding to an outlet 22 aligned with the inlet enters the joining assembly 3 through the outlet 22. The discharge chamber 20 moves along the arrangement direction L to change its position, moving the other outlet 22 to be aligned with the inlet. The front end of the handle strip of another handle strip roll 10 corresponding to the other outlet 22 enters the joining assembly 3, and the joining assembly 3 joins the rear end of the handle strip of one handle strip roll 10 with the front end of the handle strip of another handle strip roll 10.

[0121] With the above structure, after one handle strip roll 10 is conveyed, there is no need to manually pull the front end of another handle strip roll 10 into the feed inlet before conveying the other handle strip roll 10. Instead, the material discharge chamber 20 is moved along the arrangement direction L to change its position, and the other discharge port 22 is moved to align with the feed inlet. The front end of the handle strip of the other handle strip roll 10 corresponding to the other discharge port 22 enters the joining component 3. The joining component 3 joins the rear end of the handle strip of one handle strip roll 10 with the front end of the handle strip of another handle strip roll 10, thereby achieving the purpose of continuous conveying of handle strips. This reduces labor costs and the time lost by manual material pulling, making the conveying efficiency of this handle strip conveying mechanism higher when conveying handle strip rolls 10, thus improving the production efficiency of packaging bags.

[0122] More specifically, the structure and configuration of the joining component 3 are not limited, and the following example is provided.

[0123] In one implementation, such as Figure 4 As shown, the joining assembly 3 includes a support platform 30 mounted on the frame 1 and a pressing component 31.

[0124] Specifically, the pressing component 31 and the support platform 30 are in the pressing direction H (see [link to pressing direction]). Figure 1 Arranged relatively on top, such as Figure 5 As shown, the rear end of the handle strip of one handle strip roll 10 and the front end of the handle strip of another handle strip roll 10 are stacked on the support platform 30. The pressing head 32 of the pressing component 31 moves along the pressing direction H to press the rear end of one handle strip roll 10 and the front end of another handle strip roll 10 together.

[0125] More specifically, by stacking the rear end of one handle bar roll 10 and the front end of another handle bar roll 10 on the support platform 30, the contact area between the rear end of one handle bar roll 10 and the front end of another handle bar roll 10 is increased. Then, the pressing component 31 presses the rear end of one handle bar roll 10 and the front end of another handle bar roll 10 together, thereby enabling the rear end of one handle bar roll 10 and the front end of another handle bar roll 10 to be more firmly connected together, improving the connection strength between the two and reducing the risk of breakage at the connection point when the handle bar is continuously conveyed.

[0126] It should be noted that the pressing direction H can be the height direction, length direction, etc. of the frame 1, and is specifically determined by the arrangement of the pressing component 31 and the support platform 30. This embodiment does not limit it to a single direction.

[0127] More specifically, the structure and arrangement of the pressing component 31 are not limited, and the following is an example.

[0128] In one implementation, such as Figure 6 As shown, the pressing component 31 includes a driving cylinder 33 fixedly mounted on the frame 1 and whose driving end can move along the pressing direction H, and a pressing head 32 fixedly mounted on the driving end of the driving cylinder 33. When the rear end of the handle strip of one handle strip roll 10 and the front end of the handle strip of another handle strip roll 10 are stacked on the support platform 30, the pressing head 32 is driven by the driving cylinder 33 to move along the pressing direction H, so that the rear end of the handle strip of one handle strip roll 10 and the front end of the handle strip of another handle strip roll 10 are fixedly bonded together.

[0129] It should be understood that the pressing head 32 can be configured as an ultrasonic hot sealing head, an electric heating heat sealing head, etc., and this embodiment does not limit it to a single type.

[0130] Furthermore, to ensure that the rear end of one conveying handle bar roll 10 and the front end of another handle bar roll 10 can be accurately stacked on the support platform 30, in one embodiment, such as... Figure 1 and Figure 7 As shown, the joining assembly 3 also includes a strip end detection member disposed on the upstream side of the pressing member 31 in the conveying direction of the hand-held strip roll 10.

[0131] Specifically, the end detection component is located on the same side as the pressing component 31 in the pressing direction H. When the end detection component detects that the rear end of the handle strip of the current handle strip roll 10 enters the support platform 30, the driving component 211 drives the feeding chamber 20 to move and change its position along the arrangement direction L, so as to move the corresponding discharge port 22 of the other handle strip roll 10 to be aligned with the feeding port.

[0132] More specifically, by setting up an end detection component to detect the rear end of the handle bar of the current handle bar roll 10 entering the support platform 30, the corresponding outlet 22 of the other handle bar roll 10 can be moved to align with the inlet. After the front end of the other handle bar roll 10 enters the support platform 30, the rear end of the handle bar of the current handle bar roll 10 and the front end of the handle bar of the other handle bar roll 10 can be accurately stacked on the support platform 30, thereby ensuring that the rear end of the handle bar of the current handle bar roll 10 and the front end of the handle bar of the other handle bar roll 10 can be accurately fixed together. This avoids the risk of the rear end of the handle bar of the current handle bar roll 10 drooping down after the front end of the other handle bar roll 10 enters the support platform 30 before the rear end of the current handle bar roll 10 enters the support platform 30, causing deviation in the subsequent handle bar conveying.

[0133] More specifically, the structure and arrangement of the end-detection component are not limited; for example, it can be a photoelectric sensor, an ultrasonic sensor, etc. This embodiment does not limit it to a single type.

[0134] Furthermore, in order to ensure that the handle bar is wrinkle-free or folded when it enters the joining assembly 3, in one embodiment, the discharge chamber 20 is also equipped with a flattening assembly 4 located downstream of a plurality of discharge ports 22 in the conveying direction.

[0135] Specifically, the leveling assembly 4 includes multiple leveling components 40 arranged side by side and corresponding one-to-one with multiple discharge ports 22. When each handle strip roll 10 is conveyed along the conveying direction, the corresponding leveling component 40 is used to level the handle strip. This ensures that the handle strip is wrinkle-free or without folds when it enters the joining assembly 3. On the one hand, this avoids the risk that when the rear end of the handle strip of one handle strip roll 10 and the front end of the handle strip of another handle strip roll 10 are stacked on the support platform 30, the contact area between them will be small or misaligned due to wrinkles or folds, resulting in weak connection strength or failure to join. On the other hand, it avoids the risk that the packaging bag will be unsightly due to wrinkles or folds in the handle strip after it enters the feed port, is cut in the next process, and is installed on the bag body.

[0136] It should be understood that the number of multiple track flat components 40 is not limited, for example, it can be 2, 3, 5, etc., and this embodiment does not make a unique limitation.

[0137] More specifically, the structure and arrangement of the track flat component 40 are not limited, and the following is an example.

[0138] In one implementation, such as Figure 7As shown, each leveling component 40 includes at least one pair of pressure rollers 400 arranged sequentially in the conveying direction. Each pair of pressure rollers 400 is arranged opposite to each other along the height direction of the frame 1 and rotatably connected to the unloading chamber 20. When each handle strip roll 10 is conveyed along the conveying direction, the handle strip is connected to the corresponding pressure rollers 400 on both sides in the height direction of the frame 1. It should be understood that the pressure rollers 400 can be provided in 1 pair, 2 pairs, 3 pairs, etc., and this embodiment does not limit this.

[0139] Specifically, by setting the handle strip to connect with the corresponding pressure rollers 400 on both sides of the frame 1 in the height direction, the handle strip is flattened by each pair of pressure rollers 400 during the conveying process, without wrinkles or folds. Furthermore, since each pair of pressure rollers 400 is arranged opposite to each other along the height direction of the frame 1 and rotatably connected to the feeding chamber 20, the friction between the handle strip and each pair of pressure rollers 400 is reduced during the conveying process, allowing the handle strip to pass smoothly through each pair of pressure rollers 400.

[0140] Furthermore, in order to ensure that the hand-operated strip roll 10 can be continuously and gradually unfolded and conveyed, in one embodiment, such as Figure 4 and Figure 6 As shown, this handle bar conveying mechanism also includes a conveying component 5 located downstream of the joining component 3 in the conveying direction; wherein, a handle bar of a handle bar roll 10 corresponding to a discharge port 22 aligned with the feed port passes through the joining component 3 and the conveying component 5 in sequence before entering the feed port, and the conveying component 5 continuously conveys the handle bar.

[0141] Specifically, since the conveying component 5 is located downstream of the joining component 3 in the conveying direction, when conveying the handle strip, the handle strip of one handle strip roll 10 corresponding to one of the discharge ports 22 aligned with the feed port passes through the joining component 3 and the conveying component 5 in sequence before entering the feed port. The conveying component 5 can continuously convey the handle strip. When the rear end of one handle strip roll 10 enters the support platform 30, the front end of another handle strip roll 10 enters the support platform 30, and the two are pressed and fixed by the pressing component 31, the conveying component 5 continues to convey another handle strip roll 10. This process is repeated, and the handle strip is conveyed without interruption, which improves the conveying efficiency of the handle strip and further improves the production efficiency of the packaging bag.

[0142] More specifically, the structure and configuration of the transmission component 5 are not limited, and the following is an example.

[0143] In one implementation, such as Figure 4 As shown, the conveying assembly 5 includes a feeding component 50 and a storage component 51 that are sequentially mounted on the frame 1 along the conveying direction.

[0144] Specifically, during the gradual unfolding and conveying process of the handle bar roll 10, the handle bar passes sequentially through the joining component 3, the feeding component 50, and the storage component 51 along the conveying direction before being conveyed to the feed port. The feeding component 50 continuously conveys the handle bar along the conveying direction.

[0145] More specifically, as a handle strip roll 10 is gradually unfolded and conveyed, the handle strip passes sequentially along the conveying direction through the joining assembly 3, the feeding component 50, and the storage component 51 before being conveyed to the inlet. At this time, the feeding component 50 continuously conveys the handle strip along the conveying direction. When the rear end of one handle strip roll 10 enters the joining assembly 3 and the front end of another handle strip roll 10 enters the joining assembly 3, the joining assembly 3 joins the rear end of one handle strip roll 10 with the front end of another handle strip roll 10. At this time, the feeding component 50 stops conveying the handle strip along the conveying direction, while the handle strip in the storage component 51 is continued to be conveyed by the conveying device of the next process. During this process, the supply of handle strips is uninterrupted, thereby ensuring the bag making efficiency of the packaging bag.

[0146] More specifically, the structure and arrangement of the feeding component 50 and the feeding drive component 502 are not limited, and will be explained below.

[0147] In one implementation, such as Figure 6 As shown, the feeding component 50 includes a feeding drive component 502, and feeding rollers 500 and limiting rollers 501 arranged side by side and rotatably mounted on the frame 1; the storage component 51 includes a first storage roller group 510 and a second storage roller group 511 that are sequentially spaced on the frame 1 along the height direction of the frame 1.

[0148] Specifically, the first storage roller group 510 includes a plurality of first storage rollers 512 rotatably mounted on the frame 1 and arranged side by side along the conveying direction; the second storage roller group 511 includes a roller group mounting frame 514 movable along the height direction of the frame 1, and a plurality of second storage rollers 513 arranged side by side along the conveying direction on the roller group mounting frame 514 and spaced apart from each other. It should be understood that the number of the plurality of first storage rollers 512 can be 2, 3, 4, etc., and this embodiment does not limit it to a single number.

[0149] More specifically, multiple first storage rollers 512 correspond one-to-one with multiple second storage rollers 513. When the handle bar is conveyed along the conveying direction, the feeding roller 500 and the limiting roller 501 clamp the handle bar. The feeding drive component 502 drives the feeding roller 500 to rotate and continuously convey the handle bar. The handle bar sequentially passes through the storage roller pairs composed of the corresponding first storage rollers 512 and second storage rollers 513 and enters the feed inlet. Furthermore, the position of the roller assembly mounting frame 514 relative to the height direction of the frame 1 is limited by its own weight and the tension of the handle bar. It should be understood that the number of the multiple second storage rollers 513 can be 2, 3, 4, etc., and this embodiment does not impose a unique limitation.

[0150] More specifically, when the handle bar is continuously conveyed by the feeding component 50, the feeding roller 500 and the limiting roller 501 clamp the handle bar, and the feeding drive component 502 drives the feeding roller 500 to rotate and continuously convey the handle bar, so that the handle bar will not shift in position during the conveying process because it is clamped and conveyed; when the rear end of one handle bar roll 10 enters the joining component 3, and the front end of another handle bar roll 10 enters the joining component 3, the joining component 3 connects the rear end of one handle bar roll 10 with the front end of the other handle bar roll 10. When the end is engaged, the feeding drive component 502 stops driving the feeding roller 500 to rotate and convey the handle strip. At this time, the conveying device of the next process continues to convey the handle strip, thereby pulling the roller group mounting frame 514 to move along the height direction toward the first storage roller group 510, so that the handle strip between the storage roller pairs composed of the corresponding first storage rollers 512 and second storage rollers 513 can be continuously conveyed, ensuring uninterrupted conveying of the handle strip. Moreover, when changing the handle strip roll 10, there is no need to stop conveying the handle strip, which greatly improves the conveying efficiency of the handle strip.

[0151] More specifically, when the height of the roller assembly mounting frame 514 is too high, the feeding drive component 502 drives the feeding roller 500 to rotate rapidly to increase the conveying speed of the handle strip, thereby causing the roller assembly mounting frame 514 to move downward along the height direction under its own weight, thereby storing a certain length of handle strip.

[0152] Furthermore, it should be noted that the process of the handle bar entering the feed inlet by passing through the corresponding storage roller pairs consisting of the first storage roller 512 and the second storage roller 513 in sequence is as follows: the handle bar passes through a storage roller pair consisting of a first storage roller 512 and a second storage roller 513 along the conveying direction, and then passes through another storage roller pair consisting of another first storage roller 512 and another second storage roller 513 in sequence. This process is repeated for multiple storage roller pairs, thereby achieving the storage of the handle bar.

[0153] More specifically, the structure and arrangement of the feeding drive component 502 are not limited, and the following is an example.

[0154] In one embodiment, the feeding drive component 502 is configured to include a drive motor, a transmission gear fixedly sleeved on the drive end of the drive motor, a rotating gear fixedly sleeved on one end of the feeding roller 500, and a transmission belt that is connected to the transmission gear and the rotating gear respectively. The drive motor drives the transmission gear to rotate, thereby causing the transmission belt to move and drive the rotating gear to rotate. The rotation of the rotating gear is linked to the rotation of the feeding roller 500.

[0155] In another embodiment, the output end of the drive motor is fitted with a first drive gear, and the feeding drive component 502 further includes a second drive gear fixedly fitted on one end of the feeding roller 500. The first drive gear and the second drive gear mesh with each other. The drive motor drives the first drive gear to rotate, thereby driving the second drive gear to rotate, and then the second drive gear drives the feeding roller 500 to rotate.

[0156] Furthermore, after the feed roller 500 and the limiting roller 501 clamp the handle strip, the handle strip will not slip relative to the feed roller 500 and the limiting roller 501 when it is being conveyed. In one embodiment, an anti-slip layer is also provided on the outer peripheral surface of the feed roller 500, thereby increasing the friction between the feed roller 500 and the handle strip and reducing the risk of the handle strip roll 10 shifting position during conveying. It should be understood that the anti-slip layer may be a pattern formed on the outer peripheral sidewall of the feed roller 500, or the outer peripheral sidewall of the feed roller 500 may be frosted. This embodiment does not limit this to a single type.

[0157] Furthermore, to facilitate the clamping of the handle strip by the feeding roller 500 and the limiting roller 501, in one embodiment, such as Figure 8 As shown, a pair of sliders 504 are also provided on the frame 1. Both sliders 504 are slidably connected to the frame 1 and correspond one-to-one with the two ends of the limiting roller 501. Both ends of the limiting roller 501 are rotatably connected to their respective sliders 504. The frame 1 is also provided with a spring 503 corresponding to each slider 504. One end of the spring 503 is fixedly installed on the frame 1, and the other end extends radially along the limiting roller 501 and is fixedly connected to the corresponding slider 504.

[0158] Specifically, when the feeding roller 500 and the limiting roller 501 are arranged side by side, each spring 503 is in a compressed state. When it is necessary to pass the handle bar between the feeding roller 500 and the limiting roller 501, the spring 503 is further compressed, so that the limiting roller 501 moves radially, thereby facilitating the passing of the handle bar between the feeding roller 500 and the limiting roller 501.

[0159] Furthermore, to ensure that the storage component 51 can store the handle strip after each replacement of the handle strip roll 10, in one embodiment, such as... Figure 4 As shown, the conveying assembly 5 also includes a first detection component (not shown in the figure) and a second detection component (not shown in the figure) that are spaced apart on the frame 1 along the height direction of the frame 1.

[0160] Specifically, in the height direction of the frame 1, the roller assembly mounting frame 514 is located between the first detection component and the second detection component, and the first detection component and the second detection component are used to detect the position of the roller assembly mounting frame 514 in the height direction of the frame 1.

[0161] More specifically, when the rear end of one hand-held strip roll 10 enters the joining assembly 3 and the front end of another hand-held strip roll 10 enters the joining assembly 3, the joining assembly 3 joins the rear end of one hand-held strip roll 10 with the front end of another hand-held strip roll 10, and the feeding drive component 502 stops driving the feeding roller 500 to rotate and convey the hand-held strip; at this time, the conveying device of the next process continues to convey the hand-held strip, thereby pulling the roller group mounting frame 514 to move along the height direction toward the first storage roller group 510, continuously conveying the hand-held strip between the storage roller pairs composed of the corresponding first storage rollers 512 and second storage rollers 513; after the rear end of one hand-held strip roll 10 is joined with the front end of another hand-held strip roll 10, the first inspection... When the measuring component detects that the height of the roller assembly mounting frame 514 is too high, the feeding drive component 502 drives the feeding roller 500 to rotate rapidly to increase the conveying speed of the handle strip, thereby causing the roller assembly mounting frame 514 to move downward along the height direction under its own weight. After the second measuring component detects the roller assembly mounting frame 514, it adjusts the rotation speed of the feeding roller 500 driven by the feeding drive component 502 to maintain the same speed as the conveying device in the next process. The roller assembly mounting frame 514 stops moving, so that after the handle strip roll 10 is replaced, the first storage roller assembly 510 and the second storage roller assembly 511 can store a certain length of handle strip in real time, ensuring that the handle strip can be continuously conveyed during the replacement of the handle strip roll 10.

[0162] More specifically, the structure and arrangement of the first and second detection components are not limited; for example, they can be photoelectric sensors, ultrasonic sensors, etc. This embodiment does not limit them to a single type.

[0163] This embodiment also discloses a method for feeding a handle strip, which utilizes the aforementioned handle strip feeding mechanism and includes the following steps:

[0164] S1: Install multiple hand-operated strip rolls 10 into the feeding chamber 20, with each hand-operated strip roll 10 corresponding to one of the multiple discharge ports 22.

[0165] S2: The front end of a handle strip roll 10 corresponding to an outlet 22 aligned with the feed port of the next process is conveyed to the next process after passing through the joining component 3 and the conveying component 5 in sequence along the conveying direction. The conveying component 5 continuously conveys the handle strips until the rear end of the handle bag of a handle strip roll 10 passes through the corresponding outlet 22 and enters the joining component 3.

[0166] S3: The rear end of the handle bag of a handle strip roll 10 passes through a corresponding discharge port 22. The position adjustment component drives the feeding chamber 20 to move along the arrangement direction L to change its position, and moves the other discharge port 22 to be aligned with the feed port. The front end of the handle strip of the other handle strip roll 10 corresponding to the other discharge port 22 enters the joining component 3.

[0167] Specifically, using this method, when gradually unfolding and conveying multiple handle strip rolls, the conveying component 5 continuously conveys one corresponding handle strip roll. After the rear end of the handle bag of one handle strip roll 10 passes through the corresponding discharge port 22, the position adjustment component drives the feeding chamber 20 to move along the arrangement direction L to change its position, moving the other discharge port 22 to be aligned with the feed port, and the front end of the handle strip of the other handle strip roll 10 corresponding to the other discharge port 22 enters the joining component 3, thereby joining the two through the joining component 3. There is no need to manually pull the front end of the other handle strip roll 10 again to pass through the discharge port 22, the joining component 3, and the transmission component to the feed port of the next process, further reducing the time lost by manual material pulling and reducing labor costs. This makes the handling strip conveying mechanism more efficient in conveying the handle strip roll 10, thereby improving the production efficiency of packaging bags.

[0168] Furthermore, in one embodiment, during step S3, while the joining component 3 is joining, the conveying component 5 continuously conveys the handle strip, thereby ensuring uninterrupted conveying of the handle strip, improving the conveying efficiency of the handle strip, and further improving the production efficiency of the packaging bag.
