Description

Technical Field

[0001] This utility model relates to the field of bag making technology, and in particular to a handle fixing device for a tote bag. Background Technology

[0002] A tote bag is a common type of bag. When in use, a tote bag is usually opened into a cubic shape and has a handle at the opening. They are usually made of various materials, such as cloth, leather, plastic, and paper. The installation of the handles on a tote bag is crucial.

[0003] There are two common methods for installing handles in existing technologies: manual installation and machine installation. Manual installation involves manually installing the handle, while machine installation requires clamping the handle and placing it on the corresponding part of the bag material to complete the installation, such as ironing and gluing. However, existing handle installation equipment can only fix one side of the bag material at a time, and can only install one handle at a time. Since a bag usually has two handles, the handles can only be installed one by one during the installation process. This results in low handle installation efficiency, which in turn leads to low bag production efficiency.

[0004] Therefore, existing handle installation equipment suffers from low handle installation efficiency. Utility Model Content

[0005] The purpose of this application is to solve the problem of low handle installation efficiency in existing handle installation equipment.

[0006] To solve the above-mentioned technical problems, the embodiments of this application disclose a handle fixing device for a tote bag, the handle fixing device including a device bracket and at least one pair of handle fixing mechanisms.

[0007] The device support has a sheet material conveying channel extending horizontally in the middle of its height direction. At least one pair of handle fixing mechanisms are arranged sequentially on both sides of the sheet material conveying channel in the height direction. Each pair of handle fixing mechanisms is aligned with each other in the height direction, and each handle fixing mechanism fixes the handle to the sheet material of the bag passing through it.

[0008] In the conveying direction of the sheet material conveying channel, a separation mechanism is also provided upstream of the uppermost handle fixing mechanism. The separation mechanism separates the multi-layered tote bag sheets that are stacked into the sheet material conveying channel, so that each layer of tote bag sheets enters the corresponding handle fixing mechanism in each pair of handle fixing mechanisms.

[0009] By adopting the above technical solution, this application sets up a pair of handle fixing mechanisms arranged on both sides of the sheet material conveying channel in the height direction. When installing and fixing the handles, the handles on both sides of the sheet material can be installed simultaneously. Both handles can be fixed in a single operation, and the sheet material of the bag can be conveyed in a streamlined manner in the sheet material conveying channel, thus achieving higher installation efficiency and higher space utilization of the device support. Because each pair of handle fixing mechanisms is aligned with each other in the height direction, the precision and accuracy of fixing the handles are also higher.

[0010] Further, a separation mechanism can be set up to separate the multi-layer tote bag sheets entering the sheet conveying channel, so that each layer of tote bag sheets enters the corresponding handle fixing mechanism in each pair of handle fixing mechanisms. With this structure, precise layered conveying can be achieved, avoiding incorrect or offset handle installation, and making the matching degree between the tote bag sheets and the handle fixing mechanism higher. It has significant advantages of precise layering, independent conveying and efficient fixing.

[0011] More preferably, in the handle fixing device of the tote bag disclosed in this application, the separation mechanism includes a separation member disposed on the device support, wherein, in the conveying direction of the sheet material conveying channel, the height of the separation end of the separation member located in the sheet material conveying channel changes in the height direction at a predetermined period, so that the multi-layer tote bag sheets that are stacked into the sheet material conveying channel are separated in the height direction and enter a corresponding handle fixing mechanism respectively.

[0012] By employing the above technical solution, the separating component can separate multiple layers of sheet material, avoiding the problem of two layers of sheet material sticking together when fixing handles to multiple layers of tote bag sheet material simultaneously. Furthermore, the separating component separates the multiple layers of tote bag sheet material stacked into the sheet material conveying channel, making it easier to insert the end of the handle into one side of the tote bag sheet material for fixing. Moreover, the separating component changes at a predetermined cycle, allowing the multiple layers of tote bag sheet material conveyed in the sheet material conveying channel to switch between an open state and a reset state, improving the success rate of fixing the handle to one side of the tote bag sheet material, and also increasing the installation accuracy of the two handles on the tote bag sheet material.

[0013] More preferably, the separation mechanism includes a mounting frame, a drive assembly, and a separation assembly. The mounting frame is fixed to the device support in a horizontal direction and is located in the middle of the sheet material conveying channel in the height direction. The separation assembly is rotatably mounted on the mounting frame, with one end of the separation assembly extending into the sheet material conveying channel and having a separation member as a separation end. The drive assembly is drively connected to the other end of the separation assembly away from the sheet material conveying channel.

[0014] The width of the separating component is equal to the distance between each pair of handle fixing mechanisms in the height direction. The drive component drives the separating component to rotate, and the linkage separating component rotates in the sheet material conveying channel, so that the multi-layer tote bag sheets that are stacked into the sheet material conveying channel are separated in the height direction and enter the corresponding handle fixing mechanism respectively.

[0015] More preferably, the multi-layer tote bag sheet conveyed in the sheet conveying channel is formed by folding a single sheet into a double layer. The handle fixing mechanism includes two handle fixing assemblies disposed on both sides of the sheet conveying channel in the height direction. Each handle fixing assembly includes two handle fixing parts spaced apart, and the two handle fixing parts on each side are used to fix the two ends of the handle to one side of the double-layer tote bag sheet.

[0016] Using the above technical solution, the multi-layer tote bag sheet conveyed in the sheet conveying channel is folded from a single sheet into a double layer, and a set of handle fixing components (a total of four fixing components) is set on each side of the sheet conveying channel, which can simultaneously fix the handles on the left and right sides of the double-layer sheet. Therefore, the layout is more compact and the handle installation efficiency is higher.

[0017] More preferably, it also includes a handle clamping mechanism, which is located on one side of the handle fixing mechanism and clamps and conveys the handle to be fixed. Each handle clamping mechanism includes a movable clamping component and a rotating component. There are two movable clamping components, which are symmetrically arranged on both sides of the rotating component along the height direction. Each side of the rotating component facing the movable clamping component is provided with a rotatable clamping part, and each movable clamping component is provided with a handle clamping part on the side facing the rotatable clamping part.

[0018] Using the above technical solution, the handle clamping mechanism is used to clamp the handle and move the handle to the position where the handle fixing component is located.

[0019] More preferably, the handle fixing mechanism includes a heat-sealing head and a heat-sealing head seat, the heat-sealing head seat being mounted on the device support and located within the sheet material conveying channel. Furthermore, when viewed from one side of the device support towards the handle fixing mechanism, each heat-sealing head seat has two heat-sealing heads at both ends, and the two heat-sealing heads at both ends of each heat-sealing head seat are aligned with the heat-sealing head seat in the height direction.

[0020] Using the above technical solution, the heat sealing head and heat sealing head seat can quickly heat seal and fix the handle to one side of the bag sheet material. Attached Figure Description

[0036] A. Height direction; B. Conveying direction of the sheet material conveying channel. Detailed Implementation

[0037] As mentioned in the background section, there are two methods for installing handles on shopping bags in the prior art: manual installation and machine installation. When installing handles by machine, existing machines can only install one handle at a time, but finished shopping bags are generally equipped with two handles. Therefore, when installing handles, a shopping bag needs to go through two handle installation steps, resulting in low handle installation efficiency during the production of shopping bags.

[0038] To address the aforementioned technical problems, this application provides a handle fixing device for tote bags, comprising at least one pair of handle fixing mechanisms positioned vertically on both sides of a sheet material conveying channel. The sheet material conveying channel conveys multiple layers of tote bag sheet material (e.g., two layers) at a time. With this structure, in a single handle installation step, the handle fixing mechanisms located on both sides of the sheet material conveying channel can simultaneously install handles on multiple layers of tote bag sheet material. For example, when there are two layers of tote bag sheet material and two handle fixing mechanisms, two handles can be installed at once, resulting in higher handle installation efficiency and higher tote bag production efficiency. Furthermore, the more handle fixing mechanisms provided, the more handles can be installed at once.

[0039] It should be noted that the tote bag disclosed in this application can be a common paper bag, non-woven bag, plastic bag, etc. For example, when the tote bag is a non-woven bag, the handle fixing mechanism can be a common heat sealing mechanism, etc. When the tote bag is a paper bag or a plastic bag, the handle fixing mechanism can be a common adhesive mechanism, etc. This embodiment does not make specific limitations in this regard.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0041] Please see Figure 1 One preferred embodiment of this invention discloses a handle fixing device for a tote bag. The handle fixing device includes a device bracket 100 and at least one pair of handle fixing mechanisms 200. A sheet material conveying channel 110 extending horizontally is provided at the center of the device bracket 100 in the height direction, wherein the height direction is as follows... Figure 1 As shown in direction A. The sheet material conveying channel 110 is used to convey multi-layer tote bag sheets, such as conveying two-layer tote bag sheets, conveying single-sheet tote bag sheets folded into two layers, or conveying three-layer tote bag sheets, etc. When conveying tote bag sheets, a conveyor belt mechanism can be used, or a movable clamp can be used, or a conveyor belt mechanism can be used. This embodiment does not specifically limit the conveying method.

[0042] Please see Figure 1 as well asFigure 2 In this embodiment, at least one pair of handle fixing mechanisms 200 are arranged sequentially along the horizontal direction on both sides of the sheet material conveying channel 110 in the height direction. Each pair of handle fixing mechanisms 200 is aligned with each other in the height direction, and each handle fixing mechanism 200 fixes the handle to the sheet material of the bag passing through it. That is, the handle fixing mechanisms 200 are arranged in pairs on both sides of the sheet material conveying channel 110. For example, when one pair of handle fixing mechanisms 200 is provided, one handle fixing mechanism 200 is provided on each side of the sheet material conveying channel 110 in the height direction. This structure can fix two handles at a time. When two pairs of handle fixing mechanisms 200 are provided, two handle fixing mechanisms 200 are provided on each side of the sheet material conveying channel 110 in the height direction. This structure can fix four handles at a time.

[0043] It should be noted that, please refer to Figure 2 Each handle fixing mechanism 200 needs to fix both ends of a handle to the bag material. Therefore, each handle fixing mechanism 200 includes two handle fixing parts 210. The two handle fixing parts 210 are spaced apart and correspondingly fix both ends of each handle. Figure 1 This structure can secure two handles at once.

[0044] This application, by setting at least one pair of handle fixing mechanisms 200 and arranging them on both sides of the sheet material conveying channel 110 in the height direction, allows for the simultaneous installation of handles on both sides of the sheet material during handle installation. Both handles can be fixed in a single operation, and the sheet material conveying in the sheet material conveying channel 110 can achieve streamlined operation, thus increasing installation efficiency and space utilization of the device support 100. Since each pair of handle fixing mechanisms 200 is aligned with each other in the height direction, the precision and accuracy of handle fixing are also higher.

[0045] Please see Figure 1 and Figure 2 In the conveying direction of the sheet material conveying channel 110, the conveying direction of the sheet material conveying channel 110 is as follows: Figure 1 As shown in direction B, a separation mechanism 300 is also provided on the upstream side of the uppermost handle fixing mechanism 200. The separation mechanism 300 separates the multi-layer bag sheets that are stacked into the sheet material conveying channel 110, so that each layer of bag sheets enters the corresponding handle fixing mechanism 200 in each pair of handle fixing mechanisms 200.

[0046] In the handle fixing device for tote bags disclosed in this application, at least one pair of handle fixing mechanisms 200 are respectively arranged on both sides of the sheet material conveying channel 110, and each handle fixing mechanism 200 fixes the handle to the tote bag sheet material passing through it. The multi-layer tote bag sheets conveyed by the sheet material conveying channel 110 are generally bonded together. When fixing the handle, the handle to be fixed needs to be clamped and moved to the corresponding position of the tote bag sheet material and then fixed by the handle fixing mechanism 200. Therefore, when fixing the handle, it is necessary to separate and spread the multi-layer tote bag sheet material. Taking two layers of tote bag sheet material as an example, the two layers of tote bag sheet material need to be spread apart before fixing the handle, so as to ensure accurate installation of the handle and prevent the two layers of tote bag sheet material from sticking together.

[0047] Therefore, the handle fixing device for the tote bag disclosed in this application, by setting a separation mechanism 300, can separate the multi-layer tote bag sheets entering the sheet material conveying channel 110, so that each layer of tote bag sheets enters a corresponding handle fixing mechanism 200 in each pair of handle fixing mechanisms 200, thereby achieving precise layered conveying, avoiding incorrect or offset handle installation, that is, separating the multi-layer tote bag sheets, which can make the matching degree between the tote bag sheets and the corresponding handle fixing mechanism 200 higher, and has significant advantages of precise layering, independent conveying and efficient fixing.

[0048] Furthermore, in some different implementations, those skilled in the art can set the separation mechanism 300 to different mechanisms. For example, the separation mechanism 300 can be set to a separation strut, a separation wedge block, a cam, etc. This embodiment does not limit it to a single one.

[0049] Preferably, in the handle fixing device for the tote bag disclosed in this application, the separating mechanism 300 includes a separating member disposed on the device support 100. In the conveying direction of the sheet material conveying channel 110, the height of the separating end of the separating member within the sheet material conveying channel 110 changes periodically in the height direction, so that the multi-layer tote bag sheets stacked into the sheet material conveying channel 110 are separated in the height direction and each enters a corresponding handle fixing mechanism 200.

[0050] It should be noted that in this embodiment, the height of the separating end of the separating member located in the sheet material conveying channel 110 changes in the height direction at a predetermined period. This means that the separating end of the separating member can change periodically. For example, the interval size of the separating end of the separating member can change periodically. In an optimal implementation, the time when the separating end of the separating member can change periodically is matched with the time when the handle fixing mechanism 200 fixes the handle. For example, before fixing the handle, the interval size of the separating end of the separating member increases, so that the handle clamping mechanism 400 clamps the handle and conveys it to one side of the handle fixing mechanism 200. When it is necessary to fix the handle, the separating end of the separating member is reset to facilitate the handle fixing mechanism 200 to fix the handle.

[0051] Furthermore, in this embodiment, the tote bag sheet is reset after being separated in the height direction, which can reduce the offset error of the sheet and reduce the offset of the tote bag sheet during transportation during the separation process, thus ensuring the fixing accuracy of the handle.

[0052] For example, the separating end of the separating component can change periodically every second, every 0.5 seconds, or other time intervals. After the size of the separating end of the separating component increases, the handle clamping mechanism 400 can quickly clamp and transport the handle to be fixed into place, and then the handle fixing mechanism 200 fixes the two ends of the handle. It should be noted that the separating end of the separating component can be a cam, a support rod, an electromagnetic spring, etc., and this embodiment does not specifically limit it.

[0053] Taking the separation component as a cam and a separation end as an example, the cam and the separation end are connected by a drive. During the rotation of the cam, it will drive the separation rod to rotate. Within one rotation cycle, the separation end will change from increasing to decreasing in interval size, and it will also change periodically when the cam continues to rotate.

[0054] Taking the separation component as an example, the two electromagnetic springs are set between the two layers of bag material. Two electromagnetic coils are set on both sides of the two electromagnetic springs. The electromagnetic coils are energized once every 1 second or 0.5 seconds. After being energized, the electromagnetic springs move closer to the electromagnetic coils, thereby causing the two layers of bag material to separate.

[0055] This structural design avoids the problem of bonding two layers of material together when fixing handles to multiple layers of tote bag sheet material simultaneously. The separating component separates the multiple layers of tote bag sheet material stacked into the sheet material conveying channel 110, facilitating the insertion and fixing of the handle end to one side of the tote bag sheet material, specifically the inner side. Furthermore, the separating component changes at a predetermined cycle, allowing the multiple layers of tote bag sheet material conveyed in the sheet material conveying channel 110 to switch between an open and a reset state, improving the success rate of fixing the handle to one side of the tote bag sheet material and increasing the installation accuracy of the two handles on the tote bag sheet material.

[0056] In this embodiment, please refer to the following: Figure 3 and Figure 4 The separation mechanism 300 includes a mounting frame 310, a drive assembly 320, and a separation assembly 330. The mounting frame 310 is fixed to the device bracket 100 in a horizontal direction and is located in the middle of the sheet material conveying channel 110 in the height direction. The separation assembly 330 is rotatably mounted on the mounting frame 310. One end of the separation assembly 330 extends into the sheet material conveying channel 110 and has a separation member as a separation end. The drive assembly 320 is connected to the other end of the separation assembly 330 away from the sheet material conveying channel 110.

[0057] It should be noted that, in a preferred embodiment of this invention, two separation mechanisms 300 are provided, and they are disposed on both sides of the handle fixing mechanism 200.

[0058] The width of the separating component is equal to the distance between each pair of handle fixing mechanisms 200 in the height direction. The drive component 320 drives the separating component 330 to rotate, and the separating component rotates in the sheet material conveying channel 110, so that the multi-layer tote bag sheets that are stacked into the sheet material conveying channel 110 are separated in the height direction and enter the corresponding handle fixing mechanism 200 respectively.

[0059] Specifically, in this embodiment, the driving component 320 can be driven by a motor, which drives the separating component to rotate, thereby achieving periodic size changes. It can also be a motor and conveyor belt mechanism or a motor and gear mechanism. In another implementation, a cylinder can drive the rotating swing arm 322 to rotate, and then drive the separating component, which is the separating end, to rotate.

[0060] In this embodiment, the width of the separating component is precisely matched with the spacing of each pair of handle fixing mechanisms 200. The periodic rotation of the separating component 330 is controlled by the drive component 320, which can simultaneously separate multiple layers of sheet material and guide them to the corresponding fixing mechanism. This process requires no additional positioning or waiting time, significantly accelerating the production pace. Furthermore, the strict correspondence between the width of the separating component and the spacing of the handle fixing mechanism 200 ensures that the separated sheet material directly enters the designated position, avoiding handle fixing failure due to positional misalignment.

[0061] See further Figure 3 and Figure 4The mounting bracket 310 is provided with a guide groove 311 extending horizontally. The separation component 330 includes a separation shaft 331, one end of which extends into the guide groove 311 and is located in the sheet material conveying channel 110. The other end of the separation shaft 331 is rotatably connected to the drive component 320. The separation component includes two separation support rods 332 disposed at one end of the separation shaft 331. The two separation support rods 332 are spaced apart and extend parallel to the separation shaft 331. The distance between the two separation support rods 332 is greater than the shaft diameter of the separation shaft 331. For example, the distance between the two separation support rods 332 can be 5cm, 6cm, 8cm, etc. This embodiment does not specifically limit this.

[0062] The drive assembly 320 includes a drive cylinder 321 and a rotating swing arm 322. The drive cylinder 321 is fixedly mounted on the device bracket 100. The power output end of the drive cylinder 321 is rotatably connected to one end of the rotating swing arm 322, and the other end of the rotating swing arm 322 is connected to the other end of the separation shaft 331.

[0063] With this structure, the drive cylinder 321 drives the rotating swing arm 322 to rotate once, and the rotating swing arm 322 drives the separation shaft 331 to rotate once. In the initial state, the two separation struts 332 of the separation component are as follows: Figure 3 and Figure 4 As shown, the two separating support rods 332 are in a horizontal state at this time. When the rotating arm 322 drives the separating shaft 331 to rotate, the separating shaft 331 drives the two separating support rods 332 to rotate. During the rotation, when the two separating support rods 332 are in a vertical state, the two layers of bag sheet material are separated. Continuing to rotate the two separating support rods 332 returns them to a horizontal state. This achieves a predetermined periodic change in the height of the separating end of the separating component within the sheet material conveying channel 110 in the height direction.

[0064] In another embodiment disclosed in this application, the separation mechanism 300 includes a separation member disposed on the device support 100. Specifically, in the conveying direction of the sheet material conveying channel 110, the separation end of the separation member located within the sheet material conveying channel 110 gradually increases in height, so that the multi-layered tote bag sheets stacked into the sheet material conveying channel 110 are separated in the height direction and respectively enter a corresponding handle fixing mechanism 200.

[0065] The design of this structure in this embodiment involves a gradual increase in the height of the separating block along the sheet conveying direction. This causes the stacked sheets to naturally separate due to the height difference at their bottom contact surfaces as they pass through. Specifically, the multi-layered tote bag sheets are gradually lifted on the separating component as the height increases, forming a stepped separation that prevents them from sticking together. No additional drive or complex machinery is required; the structure alone is sufficient for precise separation of multi-layered sheets. The separating component can be a common wedge-shaped block, triangular separating block, trapezoidal separating block, etc., and this embodiment does not specifically limit its application to this type.

[0066] Furthermore, the separating block is directly embedded in the middle of the sheet material conveying channel 110, eliminating the need for additional transmission components or complex installation structures, thus saving equipment space and making it particularly suitable for compact production lines.

[0067] More preferably, the separating component includes a separating block disposed on the device support 100 and located in the middle of the sheet conveying channel 110 in the height direction, the cross section of the separating block being an isosceles triangle symmetrical with respect to the horizontal direction.

[0068] With this structural design, the beveled edge of the separator provides a smooth support surface for the sheet material, avoiding scratches from right-angled edges or sharp structures. Furthermore, when the sheet material passes through the separator, the stress is evenly distributed along the beveled edge, preventing excessive local pressure that could lead to deformation.

[0069] In one embodiment disclosed in this application, the multi-layer tote bag sheet conveyed within the sheet conveying channel 110 is folded from a single sheet into two layers. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 The handle fixing mechanism 200 includes two handle fixing components arranged on both sides of the sheet material conveying channel 110 in the height direction. Each handle fixing component includes two handle fixing parts 210 arranged at intervals. The two handle fixing parts 210 on each side are used to fix the two ends of the handle to one side of the double-layer bag sheet material.

[0070] In the scheme disclosed in this embodiment, the two handle fixing components are located on the upper and lower sides of the sheet material conveying channel 110, respectively, corresponding to the two-layer structure of the double-layer sheet material, for example... Figure 1 Each of the two handle fixing components on each side includes two handle fixing parts 210. The two handle fixing parts 210 can fix the two ends of a handle at the same time. The simultaneous operation on both sides shortens the processing time and improves the efficiency of fixing the handle.

[0071] In another preferred embodiment disclosed in this application, the sheet material conveying in the sheet material conveying channel 110 includes two sheets of material stacked on top of each other. The handle fixing mechanism 200 includes two handle fixing assemblies disposed on both sides of the sheet material conveying channel 110 in the height direction. Each handle fixing assembly includes four handle fixing parts 210 spaced apart, and the four handle fixing parts 210 on each side are used to fix two handles on one side of each sheet of sheet material.

[0072] This design incorporates four spaced-apart handle fixing components 210 in each handle fixing assembly. These four components can be flexibly adjusted according to the handle's specifications and shape, ensuring that handles of different sizes can be secured. It can fix four handles at once, resulting in higher efficiency.

[0073] For more details, please see Figure 5 The handle fixing device for a tote bag disclosed in this application further includes a handle clamping mechanism 400. The handle clamping mechanism 400 is located on one side of the handle fixing mechanism 200 and clamps and conveys the handle to be fixed. Each handle clamping mechanism 400 includes a movable clamping component 410 and a rotating component 420. Two movable clamping components 410 are provided and symmetrically arranged on both sides of the rotating component 420 along the height direction. Each side of the rotating component 420 facing the movable clamping component 410 is provided with a rotatable clamping part 421, and each movable clamping component 410 is provided with a handle clamping part 411 on the side facing the rotatable clamping part 421.

[0074] With this design, two movable clamping components 410 are symmetrically arranged on both sides of the rotating component 420 along the height direction, forming a layout for top-bottom clamping or simultaneous clamping on both sides. The two movable clamping components 410 on both sides of the rotating component 420 can clamp the two ends of the two handles. Through the double-sided clamping and angular rotation, dual control of the handle's spatial posture and positional accuracy is achieved. During the clamping process, the movable clamping components 410 approach the rotatable clamping part 421 of the rotating component 420 and then fix the handle. The two rotatable clamping parts 421 on both sides of the rotating component 420 clamp the two handles with the two handle clamping parts 411 respectively. Then, the rotating component 420 rotates and drives the handle to rotate to the position corresponding to the handle fixing mechanism 200. Then, the handle fixing mechanism 200 fixes the handle end to one side of the bag material.

[0075] More preferably, each handle clamping mechanism 400 includes a movable mounting base 430, and a rotating component 420 is rotatably mounted on the movable mounting base 430. Two support arms 431 extend from the movable mounting base 430, and two movable clamping components 410 are respectively mounted on the two support arms 431.

[0076] The device support 100 is provided with a movable guide rail (not shown in the figure), which extends in the same direction as the sheet material conveying channel 110. The movable mounting base 430 is movably mounted on the movable guide rail on the side away from the rotating component 420, and the two movable mounting bases 430 can reciprocate in opposite or opposite directions.

[0077] Specifically, in this embodiment, the movable mounting base 430 can be controlled and moved along the movable guide rail by means of a worm gear mechanism, a gear and rack mechanism, a timing belt mechanism, etc.

[0078] With this structural design, the movable mounting base 430 integrates the rotating component 420 and the support arm 431 to realize the overall movement and rotation function of the clamping mechanism. The two movable mounting bases 430 move closer or further away synchronously along the guide rail, which is suitable for batch clamping with a single-side handle.

[0079] In a preferred embodiment disclosed in this embodiment, the movable mounting base 430 is controlled by a movable drive motor (not shown in the figure) and a movable timing belt (not shown in the figure). The movable timing belt is connected to the power output end of the movable drive motor. The two movable mounting bases 430 are respectively fixedly connected to the two side strips of the movable timing belt. The movable drive motor drives the movable timing belt to rotate and drives the two movable mounting bases 430 to reciprocate in the same or opposite directions.

[0080] Further preferred, please refer to Figure 5 The rotating component 420 includes a rotating drive assembly and a rotating shaft 422. Rotatable clamping portions 421 are respectively provided on both end faces of the rotating shaft 422, and meshing teeth (not shown in the figure) are provided on the radial outer periphery of the rotating shaft 422. The rotating drive assembly includes a drive motor 423 and a synchronous belt 424. The output end of the drive motor 423 engages with the synchronous belt 424, which surrounds the radial outer periphery of the rotating shaft 422 and engages with the meshing teeth.

[0081] Each movable clamping component 410 includes a vertical drive component 412 and a handle clamping part 411. The handle clamping part 411 is disposed at the power output end of the vertical drive component 412, and the vertical drive component 412 can drive the handle clamping part 411 to reciprocate toward the rotatable clamping part 421. Furthermore, when viewed from the side of the device bracket 100 toward the handle clamping mechanism 400, the rotating shaft 422 and the two movable clamping components 410 are aligned in the height direction.

[0082] With this design, the drive motor 423 is driven by the radially meshing gears of the rotating shaft 422 via the synchronous belt 424, forming a high-efficiency, low-noise rotary drive system. Clamping parts are provided at both ends of the rotating shaft 422, allowing for simultaneous or independent clamping of the handle. This adapts to the synchronous processing requirements of handles on both sides. When clamping the handle synchronously, both ends of the rotating shaft 422 clamp the handle; when clamping the handle independently, only one end of the rotating shaft 422 can clamp the handle. Through the synchronous belt 424 drive and the dual-side clamping design, high-precision adjustment of the handle angle and coordinated clamping on both sides are achieved.

[0083] The vertical drive component 412 employs a linear module or cylinder to drive the handle gripping part 411 to reciprocate vertically, forming a dynamic gripping pair with the rotatable gripping part 421 of the rotating component 420. The rotating shaft 422 is aligned with the two moving gripping components 410 in the height direction, ensuring precise vertical alignment of the gripping parts and reducing gripping deviation. This results in more stable gripping and higher gripping efficiency.

[0084] In the handle fixing device of the tote bag disclosed in this application, please refer to Figure 6 The handle fixing mechanism 200 includes a heat-sealing head 211 and a heat-sealing head seat 212. The heat-sealing head seat 212 is mounted on the device support 100 and located within the sheet material conveying channel 110. When viewed from one side of the device support 100 toward the handle fixing mechanism 200, each heat-sealing head seat 212 has two heat-sealing heads 211 at both ends, and the two heat-sealing heads 211 at both ends of each heat-sealing head seat 212 are aligned with the heat-sealing head seat 212 in the height direction.

[0085] This design features an ironing head holder 212 fixed to the device bracket 100 and directly embedded within the sheet material conveying channel 110, ensuring seamless integration of the ironing action and the conveying process, reducing intermediate steps. Each ironing head holder 212 has two symmetrically arranged ironing pressure heads 211 at both ends, allowing simultaneous ironing and fixing of both sides of the handle, improving operational efficiency. The ironing pressure heads 211 are strictly aligned with the ironing head holder 212 in the height direction, ensuring uniform ironing pressure distribution and preventing handle deformation due to uneven force. This alignment design ensures the pressure heads act perpendicularly on the handle, improving ironing quality and reducing the risk of incomplete soldering or burn-through. Through height alignment, high precision and consistency in handle ironing are achieved. This results in higher space utilization, ironing efficiency, and higher ironing quality.

[0086] More specifically, see reference. Figure 2In this embodiment, each handle fixing assembly includes two handle fixing parts 210 spaced apart. The two handle fixing parts 210 are mounted on a synchronization plate 214 and controlled by a heat-sealing cylinder 213. Each handle fixing part 210 also has an adjustment mechanism 215 on one side. The heat-sealing cylinder 213 drives the synchronization plate 214 to move downward in the height direction, and then drives the two handle fixing parts 210 to move synchronously to achieve synchronous heat sealing.

[0087] Finally, see Figure 1 and Figure 2 Taking the multi-layer tote bag sheet conveyed in the sheet conveying channel 110 as an example, where a single sheet of sheet material is folded into two layers, and the handle fixing mechanism 200 includes two handle fixing components arranged on both sides of the sheet material conveying channel 110 in the height direction, each handle fixing component including two handle fixing parts 210 arranged at intervals:

[0088] The sheet material, folded from a single sheet into a double layer, is conveyed within the sheet material conveying channel 110. Figure 1 The sheet material is conveyed from left to right along the conveying direction B of the sheet material conveying channel 110, with the opening side of the double-layered tote bag sheet material close to the handle fixing component 210. During the conveying process, the double-layered tote bag sheet material passes through the separation mechanism 300. The driving cylinder 321 drives the rotating swing arm 322 to rotate, which in turn drives the separation shaft 331 and the two separation support rods 332 to rotate, causing the double-layered tote bag sheet material to separate and the spacing between them to increase. At this time, the moving clamping component 410 and the rotating component 420 of the handle clamping mechanism 400 clamp the handle, and then the rotating component 420 rotates so that the end of the handle extends into the inside of the tote bag sheet material, and aligns the end of the handle, the tote bag sheet material, the heat sealing head 211, and the heat sealing head seat 212 in the height direction. The heat-sealing cylinder 213 drives the synchronization plate 214 to move downward along the height direction, and then drives the two handle fixing components 210 to move synchronously to achieve synchronous heat sealing. The two handle fixing components on both sides of the sheet material conveying channel 110 move synchronously and heat seal one handle on each of the double-layer bag sheet materials, which greatly improves the heat sealing efficiency of the handles.
