Description

Technical Field

[0001] The utility model relates to the field of handbag processing, and particularly relates to a handle fixing device for a handbag. Background Art

[0002] A handbag, also known as a carrying bag or a tote bag, is a simple bag that usually has two handles for carrying by hand. According to different production materials, handbags can be divided into paper handbags, plastic handbags, fabric handbags (such as cotton cloth, nylon cloth), non-woven fabric handbags, kraft paper handbags, etc. In addition, from the perspective of functions and uses, handbags also include various types such as advertising handbags, gift handbags, decorative handbags, knowledge-based handbags, commemorative handbags, etc.

[0003] Taking the non-woven fabric handbag as an example, the production process of a non-woven fabric handbag usually includes steps such as sheet material cutting, handle fixing, and sheet material sewing; among them, there are various ways to fix the handle of the handbag. For example, the following 4 common fixing methods are included:

[0004] 1. Sewing fixation: The handle is sewn and fixed at a specific position on the non-woven fabric bag body by means of a sewing machine or manual sewing.

[0005] 2. Ultrasonic welding: Using the energy generated by ultrasonic vibration to make the non-woven fabric material generate high temperature and melt at the contact surface, so as to realize the fixed connection between the handle and the bag body.

[0006] 3. Adhesive fixation: Using a specific adhesive (such as hot melt adhesive, double-sided adhesive, etc.) to paste the handle at a designated position on the non-woven fabric bag body.

[0007] 4. Mechanical fixation: Connecting the handle and the non-woven fabric bag body through mechanical components such as metal fasteners and plastic fasteners.

[0008] In the above several handle fixing schemes, with the continuous progress of technology, various devices for handle fixing have been developed. Taking ultrasonic welding as an example, usually there are two hot pressing heads, which can move up and down. When the handle and the base material are conveyed between the two hot pressing heads, the two hot pressing heads move up and down or one of them moves to hot press the handle and the base material. However, when this handle fixing mechanism performs handle hot pressing, it can only perform handle hot pressing for a single model or a certain size range of handbags. For handbags with different models or large size differences, it is necessary to develop a new handle fixing machine for the handbag again, or it is necessary to make major improvements to the original machine to achieve it.

[0009] Therefore, the handle fixing device for the handbag in the prior art has the problem of low applicability. Summary of the Utility Model

[0010] The utility model aims to solve the problem of low applicability of the handle fixing device of the handbag in the prior art.

[0011] To achieve the above-mentioned purpose, the utility model provides a handle fixing device for a handbag, comprising a frame and a hot pressing mechanism arranged on the frame; wherein:

[0012] The ironing mechanism is arranged at the handle fixing station on the frame, and the ironing mechanism comprises a main ironing assembly and an auxiliary ironing assembly respectively located at two sides of the plane where the handle fixing station is located, and the main ironing assembly and the auxiliary ironing assembly are relatively movably arranged in the height direction of the frame, the inner ends of the main ironing assembly and the auxiliary ironing assembly are opposite to each other, and when the side edge of the base material of the handbag and the handle end are conveyed to the handle fixing station, the inner ends of the main ironing assembly and the auxiliary ironing assembly abut and jointly clamp the side edge of the base material of the handbag and the handle end and perform ironing and fixing; and

[0013] The ironing mechanism also includes a first movable assembly, a second movable assembly and a driving assembly which are arranged on the frame. The first movable assembly includes a first guide component connected to the frame and located on the side where the main ironing assembly is located. The second movable assembly includes a second guide component connected to the frame and located on the side where the auxiliary ironing assembly is located. The first guide component and the second guide component both extend along the conveying direction of the base material. The main ironing assembly is movably connected to the first guide component, and the auxiliary ironing assembly is movably connected to the second guide component. The driving assembly is respectively connected to the main ironing assembly and the auxiliary ironing assembly, and drives the main ironing assembly to move synchronously along the first guide component and the auxiliary ironing assembly to move synchronously along the second guide component.

[0014] By adopting the above technical solution, the handle fixing device provided by the utility model can realize the automatic ironing and fixing of the handle and the base material of the handbag through the ironing mechanism, which can greatly improve the production efficiency, and can significantly reduce manual operation and reduce labor intensity. The main ironing assembly and the auxiliary ironing assembly can move relatively in the height direction of the frame, and synchronous movement is achieved through the first moving assembly, the second moving assembly and the driving assembly, ensuring the accuracy of the ironing process.

[0015] Furthermore, the inner ends of the main ironing component and the auxiliary ironing component jointly clamp the side edges of the handbag base material and the ends of the handle during the ironing process, ensuring the accuracy and stability of the ironing position, avoiding problems such as position offset or loose fixation that may be caused by manual ironing, and achieving a firm connection between the handle and the handbag base material, thereby improving the overall quality and service life of the handbag.

[0016] Furthermore, the positions of the main ironing assembly and the auxiliary ironing assembly on the frame can be relatively moved. This design enables the device to be suitable for the production of handbags of different sizes and shapes, and has greater applicability.

[0017] Therefore, while improving production efficiency and reducing labor intensity, the handle fixing device provided by the present utility model can also be used to process bags of different specifications or different size ranges, thereby enhancing the applicability of the handle fixing device.

[0018] According to the handle fixing device of the shopping bag provided by the present utility model, the main heat-sealing assembly includes a first main heat-sealing member and a second main heat-sealing member that are arranged at a heat-sealing distance interval along the conveying direction of the base material, and the auxiliary heat-sealing assembly includes a first auxiliary heat-sealing member and a second auxiliary heat-sealing member that are arranged at a heat-sealing distance interval; wherein,

[0019] The first main heat-sealing member and the second main heat-sealing member are movably arranged relative to each other on the first guiding member, and the first auxiliary heat-sealing member and the second auxiliary heat-sealing member are movably arranged relative to each other on the second guiding member; and, in the conveying direction of the base material, the distance between the first main heat-sealing member and the second main heat-sealing member is always equal to the distance between the first auxiliary heat-sealing member and the second auxiliary heat-sealing member.

[0020] Adopting the above technical solution, in the conveying direction of the base material, the distance between the first main heat-sealing member and the second main heat-sealing member is always equal to the distance between the first auxiliary heat-sealing member and the second auxiliary heat-sealing member. This design ensures the synchronism and consistency of the heat-sealing members on both sides during the heat-sealing process, thereby avoiding the problem of poor heat-sealing caused by position deviation, improving the connection stability between the handle and the bag body, and further improving the overall quality of the product.

[0021] Furthermore, the first main heat-sealing member and the first auxiliary heat-sealing member, and the second main heat-sealing member and the second auxiliary heat-sealing member respectively form two pairs of heat-sealing mechanisms that work in parallel. This parallel structural design not only enables the heat-sealing mechanisms to perform corresponding actions independently, reducing the interference, but also can improve the heat-sealing efficiency and shorten the production cycle.

[0022] Furthermore, since each heat-sealing member is movably arranged relative to each other on the guiding member, it can be flexibly adjusted according to the base materials of shopping bags of different sizes and shapes. This design enhances the adaptability and flexibility of the device, enabling it to meet diverse production requirements. And by adjusting the distance and position between each heat-sealing member, the device can be compatible with the production of shopping bags of multiple specifications, reducing the production cost.

[0023] Even further, since the heat-sealing members act simultaneously on both sides and are relatively fixed in position, it can ensure that the handle receives uniform and stable forces during the heat-sealing process, helping to improve the connection strength between the handle and the shopping bag base material, thereby enhancing the overall stability of the product.

[0024] According to the handle fixing device of the handbag provided by the present utility model, the driving assembly includes: two first driving components respectively drivingly connected to the first main welding component and the second main welding component, and two second driving components respectively drivingly connected to the first auxiliary welding component and the second auxiliary welding component; wherein,

[0025] The two first driving components are respectively fixedly arranged on the frame and at both ends of the first guiding component; and the two first driving components respectively drive the first main welding component and the second main welding component to move along the first guiding component in opposite directions;

[0026] The two second driving components are respectively fixedly arranged on the frame and at both ends of the second guiding component; and the two second driving components respectively drive the first auxiliary welding component and the second auxiliary welding component to move along the second guiding component in opposite directions.

[0027] With the above technical solution, the two first driving components respectively drive the first main welding component and the second main welding component to move along the first guiding component in opposite directions. Similarly, the two second driving components also drive the first auxiliary welding component and the second auxiliary welding component to move in opposite directions. This two-way driving method ensures that the welding components can accurately move to the predetermined positions, thereby realizing the accurate docking of the handle and the handbag base material. And since the driving components are respectively located at both ends of the guiding component and the opposite or approaching movement of the welding components is realized through synchronous control, it can be ensured that during the welding process, the positions of the two side welding components always remain consistent, improving the synchronism and accuracy of welding.

[0028] During use, by adjusting the output power and driving speed of the driving components, the moving speed and position of the welding components can be flexibly adjusted to adapt to handbag base materials of different sizes and shapes.

[0029] Furthermore, since the welding components move in opposite directions simultaneously on both sides for welding, it can be ensured that the handle receives uniform and stable forces during the welding process, avoiding the problem of poor welding caused by uneven force and improving the product yield and consistency.

[0030] According to the handle fixing device of the handbag provided by the present utility model, the conveying direction of the base material is horizontal, and in the vertical direction, the main welding assembly is located above the auxiliary welding assembly, and the main welding assembly and the auxiliary welding assembly move relatively in the vertical direction; wherein,

[0031] The first guiding component is arranged on the frame near the top in the vertical direction, and the first guiding component includes a first sliding rail fixedly connected to the frame and extending along the conveying direction of the base material. The first driving component includes a first moving rod and a first driving motor; the first main stamping component and the second main stamping component are slidably connected to the first sliding rail. Two first driving motors are respectively arranged on two sides of the first main stamping component and the second main stamping component away from each other. One end of the first moving rod is drivingly connected to the first main stamping component or the second main stamping component, and the other end is drivingly connected to the driving shaft of the corresponding first driving motor;

[0032] The second guiding component is arranged on the frame near the bottom in the vertical direction, and the second guiding component includes a second sliding rail fixedly connected to the frame and extending along the conveying direction of the base material. The second driving component includes a second moving rod and a second driving motor; the first auxiliary stamping component and the second auxiliary stamping component are slidably connected to the second sliding rail. Two second driving motors are respectively arranged on two sides of the first auxiliary stamping component and the second auxiliary stamping component away from each other. One end of the second moving rod is drivingly connected to the first auxiliary stamping component or the second auxiliary stamping component, and the other end is drivingly connected to the driving shaft of the corresponding second driving motor.

[0033] With the above technical solution, the main stamping assembly is located above the auxiliary stamping assembly. This hierarchical design effectively utilizes the vertical space, making the floor area of the entire device in the horizontal direction smaller, which is beneficial to the space optimization of the production workshop. And due to the relative movement of the stamping assemblies in the vertical direction, the operator can more conveniently access and maintain the equipment, improving the convenience and safety of operation.

[0034] Furthermore, the first sliding rail and the second sliding rail respectively extend along the conveying direction of the base material, providing a stable moving track for the stamping components. Through the separate driving control of the first driving motor and the second driving motor, the stamping components can move along a predetermined trajectory, ensuring the accuracy and stability of the stamping position. And the two first driving motors and the two second driving motors are respectively located on two sides of the stamping components away from each other. Through the driving connection of the first moving rod and the second moving rod, the synchronous movement of the stamping components is realized. This design helps to reduce the position deviation caused by mechanical errors and improve the stamping accuracy.

[0035] Furthermore, due to the relative movement of the stamping components in the vertical direction, the influence of external forces is small, which can ensure that the handle receives uniform and stable forces during the stamping process, avoiding the problem of poor stamping caused by uneven force.

[0036] According to the handle fixing device of the handbag provided by the present invention, the first driving component further includes a first nut assembly, and the second driving component further includes a second nut assembly; wherein,

[0037] The first nut assembly is drivingly connected to the drive shaft of the first drive motor, and the second nut assembly is drivingly connected to the drive shaft of the second drive motor. Threads are formed at positions of the two first moving rods and the two second moving rods close to their other ends. The other end of the first moving rod is threadedly connected to the first nut assembly; the other end of the second moving rod is threadedly connected to the second nut assembly; and,

[0038] The threads on the two first moving rods are opposite, and the threads on the two second moving rods are opposite.

[0039] With the above technical solution, since the two first moving rods and the two second moving rods are respectively threadedly connected to the first nut assembly and the second nut assembly, and the thread directions are opposite, when the drive motor rotates, the two moving rods will move synchronously but in opposite directions. This design ensures that the main ironing member and the auxiliary ironing member can accurately and synchronously adjust their positions during the ironing process. The synchronous and reverse movement mode helps to reduce errors caused by mechanical vibration or imbalance, and can improve the stability of the ironing process.

[0040] Furthermore, the design of threaded connection and synchronous reverse movement can reduce the deviation of the ironing position caused by mechanical errors or improper manual operation, and improve the overall consistency and aesthetics of the product.

[0041] According to the handle fixing device of the handbag provided by the present utility model, both the first nut assembly and the second nut assembly include a nut sleeve and a belt member; wherein,

[0042] The nut sleeve is coaxially arranged with the first moving rod and / or the second moving rod, the power output end of the belt member is drivingly connected to the nut sleeve, and the power input end of the belt member is drivingly connected to the drive shaft of the first drive motor or the second drive motor.

[0043] With the above technical solution, as an intermediate component for power transmission, the belt member can stably transmit the power of the drive motor to the nut sleeve, thereby driving the movement of the moving rod. This design reduces the energy loss during the power transmission process, improves the efficiency of power transmission. The belt member has a certain elasticity and can absorb and relieve mechanical vibration to a certain extent, making the entire ironing process smoother and reducing errors and damages caused by vibration.

[0044] Furthermore, the nut sleeve is coaxially arranged with the first moving rod and / or the second moving rod, ensuring the linearity and accuracy of power transmission, and can reduce errors caused by offset or misalignment, improving the accuracy of the ironing position.

[0045] According to the handle fixing device of the handbag provided by the present utility model, a rotating connection member is provided at one end of the first moving rod and one end of the second moving rod; wherein,

[0046] One end of the first moving rod is rotatably connected to the upper end of the first main welding member or the upper end of the second main welding member through a rotating connection member;

[0047] One end of the second moving rod is rotatably connected to the upper end of the first auxiliary welding member or the upper end of the second auxiliary welding member through a rotating connection member.

[0048] With the above technical solution, the rotating connection member allows the welding member to make a certain angle adjustment while moving. By adjusting the angle of the welding member, the welding error caused by the irregular shape or dimensional deviation of the base material can be reduced, and the accuracy of the handle fixation can be improved. Moreover, the rotating connection member can provide a stable support point for the welding member, so that the welding member can maintain a stable posture during the welding process, reducing the position deviation caused by vibration or impact.

[0049] According to the handle fixing device of the handbag provided by the present utility model, both the first main welding member and the second main welding member are set as heat welding members, and both the first auxiliary welding member and the second auxiliary welding member are set as ultrasonic generating members.

[0050] With the above technical solution, the first main welding member and the second main welding member melt and bond the handle and the handbag base material together at high temperature by heat welding. Using heat welding technology can ensure full contact and melting of the bonding surface, thereby forming a firm bonding layer and improving the strength and durability of the handle fixation. Moreover, the first auxiliary welding member and the second auxiliary welding member utilize the energy generated by ultrasonic vibration to generate microscopic friction and heat at the contact surface between the handle and the handbag base material, and then achieve bonding. The ultrasonic bonding technology has the advantages of strong penetration, fast bonding speed, high bonding strength, etc., and can further enhance the firmness of the handle fixation.

[0051] Furthermore, since the heat welding member adopts the above structure, it is more conducive to controlling the temperature and heating duration, and can achieve uniform bonding between the handle and the handbag base material, avoiding poor bonding or local overheating, which helps to improve the welding quality and make the handle fixation more flat and beautiful. And the ultrasonic bonding technology does not require additional adhesives, so the appearance problems caused by adhesive residues can be avoided. At the same time, ultrasonic bonding can also reduce defects such as bubbles and cracks generated by heat welding, making the appearance of the handle fixation more perfect.

[0052] Furthermore, the use of the heat welding member and the ultrasonic generating member can also achieve rapid bonding of the handle, which helps to shorten the production cycle and improve production efficiency.

[0053] Furthermore, the ultrasonic bonding technology does not require additional heat sources and adhesives, thus saving energy and reducing pollution. Moreover, since less heat is generated during the bonding process, it also helps to lower the temperature and humidity in the workshop and improve the working environment.

[0054] According to the handle fixing device of the handbag provided by the present utility model, both the first main bonding member and the second main bonding member include a lifting cylinder and a bonding block provided at the lower end of the lifting cylinder;

[0055] Both the first auxiliary bonding member and the second auxiliary bonding member include an ultrasonic generator and a forming block provided at the top of the ultrasonic generator, and the bonding block is adapted to the forming block; wherein

[0056] The end of each forming block includes a first forming area and a second forming area arranged in sequence along the direction of base material conveyance. Among them, one of the first forming area and the second forming area is set as a planar structure, and the other is set as a concave-convex structure.

[0057] Adopting the above technical solution, the matching design of the bonding block and the forming block ensures the precise alignment of the handle and the handbag base material during the bonding process, can reduce the problem of poor bonding caused by position deviation, and improves the bonding accuracy.

[0058] Furthermore, the different structural designs (plane and concave-convex) of the first forming area and the second forming area can adapt to the handle requirements of different shapes and structures. Among them, the planar structure is suitable for the bonding of simple straight lines, while the concave-convex structure can better adapt to handles with special shapes or structures, such as handle designs with grooves or protrusions.

[0059] Furthermore, through the lifting cylinder, the bonding block can apply appropriate pressure to the contact surface between the handle and the handbag base material to ensure the tight bonding between the two, thereby improving the bonding strength.

[0060] Moreover, based on the above mechanism, the device can also be adjusted according to different handle shapes and sizes. By replacing the forming blocks of different shapes, it can adapt to the production requirements of various types of handbags, improving the flexibility of the equipment.

[0061] According to the handle fixing device of the handbag provided by the present utility model, the first main bonding member and the second main bonding member further include a mounting table, and the mounting table is provided with a first mounting position and a second mounting position arranged in sequence along the direction of base material conveyance, and the bonding block is selectively connected to the first mounting position or the second mounting position; wherein,

[0062] The installation table is provided with a pressing plate and a connecting side plate. The pressing plate is connected to the installation table along the length direction of the installation table, and the connecting side plate is connected to the installation table along the height direction of the installation table. The first installation position and the second installation position are located in the area formed by the connecting side plate and the pressing plate. Moreover, the hot melt block is detachably connected to the connecting side plate, and a pressing protrusion with a table-like structure is formed on the hot melting surface of the hot melt block.

[0063] With the above technical solution, the first installation position and the second installation position arranged along the base material conveying direction on the installation table allow the hot melt block to be selectively connected to different positions according to actual needs. This design increases the flexibility of the equipment, enabling the same set of equipment to adapt to the base materials of handbags with different sizes, shapes or hot melting positions.

[0064] Furthermore, the detachable connection design between the hot melt block and the connecting side plate makes the replacement and maintenance of the hot melt block simple and fast. And when it is necessary to replace the hot melt block with a different shape or size, only the connection of the current hot melt block needs to be released, and a new hot melt block can be installed without large-scale adjustment of the entire equipment. The pressing protrusion with a table-like structure formed on the hot melting surface of the hot melt block can generate greater pressure during the hot melting process, and can make the hot melting force be more evenly distributed on the contact surface between the handle and the handbag base material, avoiding the hot melting quality problems caused by excessive or too small local force, contributing to the tight bonding between the handle and the handbag base material. This design improves the strength and stability of the hot melting, and reduces the problem of the handle falling off due to insecure bonding.

[0065] Furthermore, the pressing plate is connected to the installation table along the length direction of the installation table, while the connecting side plate is connected to the installation table along the height direction of the installation table, and the two together form the working area of the hot melt block. This design ensures the stability and reliability of the hot melt block during the working process, avoiding the position deviation caused by vibration or impact.

[0066] According to the handle fixing device of the handbag provided by the present invention, it further includes a handle base material supply mechanism for conveying the handle base material to the handle fixing station, a cutting mechanism for cutting the handle base material into a handle with a preset length, and a handle bending mechanism for bending the handle conveyed to the handle fixing station at a preset angle. The handle base material supply mechanism, the cutting mechanism, and the handle bending mechanism are sequentially arranged on the frame in the conveying direction of the handle; wherein,

[0067] The handle base material supply mechanism includes a storage rack, a conveying assembly, and a hemming device; the storage rack is arranged on the frame and extends out of the frame towards one side of the frame, the hemming device is arranged on the frame below the handle fixing station for hemming the handle base material, and the conveying assembly includes a plurality of conveyor rollers arranged between the cutting mechanism and the hemming device, and the handle base material hemmed by the hemming device is conveyed to the cutting mechanism via the plurality of conveyor rollers;

[0068] The cutting mechanism includes a cutting knife frame arranged on the frame and a cutting knife movably arranged on the cutting knife frame, wherein the cutting blade of the cutting knife faces the conveying path of the handle substrate, and the handle substrate passing through the cutting knife is cut into handles of a preset length;

[0069] The handle bending mechanism includes a first clamping assembly and a second clamping assembly movably arranged along the base material conveying direction. The first clamping assembly clamps one end of the handle, and the second clamping assembly clamps the other end of the handle. The first clamping assembly and the second clamping assembly move toward each other to bend the handle at a preset angle.

[0070] By adopting the above technical solution, the entire process of supplying, cutting and bending the handle base material is automated, reducing manual operations and significantly improving production efficiency. In addition, the various mechanisms are arranged in sequence in the conveying direction of the handle, ensuring that the handle base material can be continuously processed into finished handles, thereby achieving efficient production.

[0089] The shopping bag includes a paper shopping bag, a plastic shopping bag, a fabric shopping bag (such as cotton cloth, nylon cloth), a non-woven fabric shopping bag, and a kraft paper shopping bag, etc. Among them, the non-woven fabric shopping bag belongs to an easily heat-sealable material. Therefore, it has gradually become the existing mainstream solution to fix the handle of the non-woven fabric shopping bag by means of heat sealing.

[0090] For the handle fixing devices in the prior art, many handle fixing devices only consider shopping bags of specific sizes or models during design. The distance between the heat-sealing heads and the moving range are fixed, and parameters such as the position, angle, and moving range of the heat-sealing heads are often non-adjustable or have a limited adjustment range, resulting in the device being unable to flexibly cope with shopping bags of different sizes and shapes.

[0091] Currently, for shopping bags, more and more users have the need for personalized customization. For enterprises that need to produce shopping bags of multiple models and sizes, if they need to re-develop or improve the handle fixing device every time they change the model, it will greatly increase the production cost and time cost. With the continuous development of the market and the diversification of consumer demands, the styles, sizes, and materials of shopping bags are also constantly changing, and the existing handle fixing devices are difficult to meet this diversified market demand.

[0092] Therefore, the handle fixing device of the shopping bag in the prior art of the present utility model has the problem of low applicability.

When in use, the main ironing assembly and the auxiliary ironing assembly can be adjusted in position in the base material conveying direction through the first moving assembly and the second moving assembly, so that the handle fixing device can be used to fix the handles of handbags of different specifications or different size ranges, thereby solving the above problem.

[0094] In order to more clearly introduce the handle fixing device of the handbag provided by the utility model, the following is further described in conjunction with the accompanying drawings:

[0095] The handle fixing device of this handbag, such as Figures 1-4 As shown, it includes a frame 10 and a hot pressing mechanism 100 arranged on the frame 10.

[0096] Specifically, the ironing mechanism 100 is arranged at the handle fixing station 101 on the frame 10, and the ironing mechanism 100 includes a main ironing component 110 and an auxiliary ironing component 120 respectively located on both sides of the plane where the handle fixing station 101 is located, and the main ironing component 110 and the auxiliary ironing component 120 are relatively movably arranged in the height direction of the frame 10, and the inner ends of the main ironing component 110 and the auxiliary ironing component 120 are opposite to each other, and when the side edge of the base material of the handbag and the handle end are conveyed to the handle fixing station 101, the inner ends of the main ironing component 110 and the auxiliary ironing component 120 abut and jointly clamp the side edge of the base material of the handbag and the handle end for ironing and fixing.

[0097] Furthermore, if Figure 4As shown, the ironing mechanism 100 also includes a first moving assembly 130, a second moving assembly 140 and a driving assembly arranged on the frame 10. The first moving assembly 130 includes a first guide component 131 connected to the frame 10 and located on the side where the main ironing assembly 110 is located. The second moving assembly 140 includes a second guide component 141 connected to the frame 10 and located on the side where the auxiliary ironing assembly 120 is located. The first guide component 131 and the second guide component 141 both extend along the conveying direction of the base material. The main ironing assembly 110 is movably connected to the first guide component 131, and the auxiliary ironing assembly 120 is movably connected to the second guide component 141. The driving assembly is respectively connected to the main ironing assembly 110 and the auxiliary ironing assembly 120, and drives the main ironing assembly 110 to move synchronously along the first guide component 131 and the auxiliary ironing assembly 120 to move synchronously along the second guide component 141.

[0098] It should be understood that the handle fixing station 101 may be a plane extending in the horizontal direction, and the main ironing assembly 110 and the auxiliary ironing assembly 120 may be movably arranged in the vertical direction. Figure 3 Left and right directions shown.

[0099] Furthermore, the ironing mechanism 100 may also include a moving table (not shown) for linking the main ironing component 110 and the auxiliary ironing component 120 to move in the width direction of the base material. The moving table may include two sets of slide rails, and the main ironing component 110 and the auxiliary ironing component 120 are respectively arranged on the slide rails on both sides. When dealing with base materials of different widths, the positions of the main ironing component 110 and the auxiliary ironing component 120 in the width direction of the base material can be adjusted by the moving table.

[0100] Specifically, one of the main ironing assembly 110 and the auxiliary ironing assembly 120 may be movable in the vertical direction, or both may be movable in the vertical direction. For example, the main ironing assembly 110 may be movable in the vertical direction, and the main ironing assembly 120 may not be movable:

[0101] A lifting cylinder 113 is provided on the top of the main ironing component 110, and the auxiliary ironing component 120 is relatively fixed in the vertical direction. In actual application of this structure, the cylinder body of the lifting cylinder 113 is movably connected to the first guide component 131, and the bottom of the auxiliary ironing component 120 is movably connected to the second guide component 141. When in use, when fixing the handles of handbags of different sizes, due to the different lengths of the handles, the fixed distances at both ends are different. The lifting cylinder 113 can be moved by the first guide component 131 to drive the main ironing component 110 to move and adjust its position, and the auxiliary ironing component 120 can be moved by the second guide component 141 to adjust its position, thereby adapting to handbags of different sizes.

[0102] This handle fixing device can achieve the automatic heat-sealing and fixing of the handle and the base material of the handbag through the heat-sealing mechanism 100, which can greatly improve the production efficiency, significantly reduce manual operations, and lower the labor intensity. Moreover, the main heat-sealing component 110 and the auxiliary heat-sealing component 120 can move relative to each other in the height direction of the frame 10, and achieve synchronous movement through the first moving component 130, the second moving component 140, and the driving component, ensuring the accuracy of the heat-sealing process.

[0103] Furthermore, the inner ends of the main heat-sealing component 110 and the auxiliary heat-sealing component 120 jointly clamp the side edge of the handbag base material and the end of the handle during the heat-sealing process, ensuring the accuracy and stability of the heat-sealing position, avoiding problems such as position deviation or insecure fixation that may occur during manual heat-sealing, and enabling a firm connection between the handle and the handbag base material, improving the overall quality and service life of the handbag.

[0104] Moreover, the positions of the main heat-sealing component 110 and the auxiliary heat-sealing component 120 on the frame 10 can move relative to each other. This design enables the device to be applicable to the production of handbags with different sizes and shapes, with stronger applicability.

[0105] Therefore, while improving the production efficiency and reducing the labor intensity, the handle fixing device provided by the present utility model can also be used to process bags with different specifications or different size ranges, thereby enhancing the applicability of the handle fixing device.

[0106] Please refer to Figure 4 and Figure 5 , and the structures of the main heat-sealing component 110, the auxiliary heat-sealing component 120, the first moving component 130, the second moving component 140, and the driving component will be further introduced in detail below:

[0107] There is no unique requirement for the structures of the main heat-sealing component 110 and the auxiliary heat-sealing component 120. For example, the main heat-sealing component 110 can be a hot iron head, and the auxiliary heat-sealing component 120 can be an ultrasonic generator.

[0108] The main heat-sealing component 110 and the auxiliary heat-sealing component 120 can be set as an integral structure or a split structure.

[0109] In an implementable embodiment, the main heat-sealing component 110 includes a first main heat-sealing member 111 and a second main heat-sealing member 112 arranged at intervals of a heat-sealing distance along the conveying direction of the base material, and the auxiliary heat-sealing component 120 includes a first auxiliary heat-sealing member 121 and a second auxiliary heat-sealing member 122 arranged at intervals of a heat-sealing distance.

[0110] Specifically, the first main welding component 111 and the second main welding component 112 are arranged on the first guiding component 131 in a relatively movable manner, and the first auxiliary welding component 121 and the second auxiliary welding component 122 are arranged on the second guiding component 141 in a relatively movable manner; moreover, in the conveying direction of the base material, the distance between the first main welding component 111 and the second main welding component 112 is always equal to the distance between the first auxiliary welding component 121 and the second auxiliary welding component 122.

[0111] Both the first main welding component 111 and the second main welding component 112 can be set as hot welding heads, for example, they can be hot welding heads with a block structure, and the first auxiliary welding component 121 and the second auxiliary welding component can be set as ultrasonic generators.

[0112] Based on the design of the above structure, in the conveying direction of the base material, the distance between the first main welding component 111 and the second main welding component 112 is always equal to the distance between the first auxiliary welding component 121 and the second auxiliary welding component 122. This design ensures the synchronization and consistency of the welding components on both sides during the welding process, thus avoiding the problem of poor welding caused by position deviation, improving the connection stability between the handle and the bag body, and further improving the overall quality of the product.

[0113] Furthermore, the first main welding component 111 and the first auxiliary welding component 121, and the second main welding component 112 and the second auxiliary welding component 122 respectively form two pairs of welding mechanisms 100 working in parallel. This parallel structure design not only enables the welding mechanism 100 to perform corresponding actions independently, reducing the interference, but also can improve the welding efficiency and shorten the production cycle.

[0114] Furthermore, since each welding component is arranged on the guiding component in a relatively movable manner, it can be flexibly adjusted according to the base materials of handbags with different sizes and shapes. This design enhances the adaptability and flexibility of the device, enabling it to meet diverse production requirements. And by adjusting the distance and position between each welding component, the device can be compatible with the production of handbags of various specifications, reducing the production cost.

[0115] Even further, since the welding components act simultaneously on both sides and the positions are relatively fixed, it can ensure that the handle receives uniform and stable forces during the welding process, which helps to improve the connection strength between the handle and the handbag base material, thereby enhancing the overall stability of the product.

[0116] The structure of the driving component is not limited. Each welding component can adopt a separate driving part, or two can share the same driving part, or four welding components can share a driving component.

[0117] Taking the example that each heat-sealing component can be provided with a separate driving part, the driving assembly includes: two first driving parts 151 respectively drivingly connected to the first main heat-sealing component 111 and the second main heat-sealing component 112, and two second driving parts 152 respectively drivingly connected to the first auxiliary heat-sealing component 121 and the second auxiliary heat-sealing component 122.

[0118] Specifically, the two first driving parts 151 are respectively fixedly arranged on the frame 10 at both ends of the first guiding part 131; and the two first driving parts 151 respectively drive the first main heat-sealing component 111 and the second main heat-sealing component 112 to move along the first guiding part 131 in opposite directions; the two second driving parts 152 are respectively fixedly arranged on the frame 10 at both ends of the second guiding part 141; and the two second driving parts 152 respectively drive the first auxiliary heat-sealing component 121 and the second auxiliary heat-sealing component 122 to move along the second guiding part 141 in opposite directions.

[0119] Based on the above structure, the two first driving parts 151 respectively drive the first main heat-sealing component 111 and the second main heat-sealing component 112 to move along the first guiding part 131 in opposite directions. Similarly, the two second driving parts 152 also drive the first auxiliary heat-sealing component 121 and the second auxiliary heat-sealing component 122 to move in opposite directions. This two-way driving method ensures that the heat-sealing components can accurately move to the predetermined positions, thereby realizing the accurate docking of the handle and the base material of the handbag. And since the driving parts are respectively located at both ends of the guiding part and the heat-sealing components move towards or away from each other through synchronous control, it can be ensured that during the heat-sealing process, the positions of the heat-sealing components on both sides always remain consistent, improving the synchronism and accuracy of heat-sealing.

[0120] During use, by adjusting the output power and driving speed of the driving parts, the moving speed and position of the heat-sealing components can be flexibly adjusted to adapt to the base materials of handbags with different sizes and shapes.

[0121] Furthermore, since the heat-sealing components move simultaneously and in opposite directions on both sides for heat-sealing, it can be ensured that the handle receives uniform and stable forces during the heat-sealing process, avoiding the problem of poor heat-sealing caused by uneven force and improving the yield and consistency of the product.

[0122] The structure of the driving part is not limited. For example, it can be various easily controllable drivers such as a stepper motor, a servo motor, etc.

[0123] Furthermore, please refer to Figure 4 and Figure 5, in the handle fixing device of the handbag provided by the present utility model, the conveying direction of the base material is horizontal. And, in the vertical direction, the main ironing assembly 110 is located above the auxiliary ironing assembly 120, and the main ironing assembly 110 and the auxiliary ironing assembly 120 move relative to each other in the vertical direction.

[0124] Specifically, the first guiding member 131 is disposed on the frame 10 near the top in the vertical direction, and the first guiding member 131 includes a first sliding rail 1311 fixedly connected to the frame 10 and extending along the conveying direction of the base material. The first driving member 151 includes a first moving rod 1512 and a first driving motor 1513; the first main ironing member 111 and the second main ironing member 112 are slidably connected to the first sliding rail 1311. The two first driving motors 1513 are respectively disposed on the two sides of the first main ironing member 111 and the second main ironing member 112 away from each other. One end of the first moving rod 1512 is drivingly connected to the first main ironing member 111 or the second main ironing member 112, and the other end is drivingly connected to the driving shaft of the corresponding first driving motor 1513.

[0125] The second guiding member 141 is disposed on the frame 10 near the bottom in the vertical direction, and the second guiding member 141 includes a second sliding rail 1411 fixedly connected to the frame 10 and extending along the conveying direction of the base material. The second driving member 152 includes a second moving rod 1522 and a second driving motor 1523; the first auxiliary ironing member 121 and the second auxiliary ironing member 122 are slidably connected to the second sliding rail 1411. The two second driving motors 1523 are respectively disposed on the two sides of the first auxiliary ironing member 121 and the second auxiliary ironing member 122 away from each other. One end of the second moving rod 1522 is drivingly connected to the first auxiliary ironing member 121 or the second auxiliary ironing member 122, and the other end is drivingly connected to the driving shaft of the corresponding second driving motor 1523.

[0126] Based on the above structure, the main ironing assembly 110 is located above the auxiliary ironing assembly 120. This hierarchical design effectively utilizes the vertical space, making the floor area of the entire device in the horizontal direction smaller, which is beneficial to the space optimization of the production workshop. And due to the relative movement of the ironing assemblies in the vertical direction, the operator can more conveniently access and maintain the equipment, improving the operation convenience and safety.

[0127] Further, the first slide rail 1311 and the second slide rail 1411 extend along the conveying direction of the base material respectively, providing a stable moving track for the welding component. Through the independent drive control of the first drive motor 1513 and the second drive motor 1523, the welding component can move along a predetermined track, ensuring the accuracy and stability of the welding position. Moreover, the two first drive motors 1513 and the two second drive motors 1523 are respectively located on the two sides of the welding component away from each other. Through the transmission connection of the first moving rod 1512 and the second moving rod 1522, the synchronous movement of the welding component is realized. This design helps to reduce the position deviation caused by mechanical errors and improve the welding precision.

[0128] Further, due to the relatively small influence of external forces on the relative movement of the welding component in the vertical direction, it can ensure that the handle receives uniform and stable forces during the welding process, avoiding the problem of poor welding caused by uneven stress.

[0129] Further, please refer to Figure 4 and Figure 5 , in the handle fixing device of the handbag provided by the present utility model, the first drive component 151 further includes a first nut assembly 1511, and the second drive component 152 further includes a second nut assembly 1521.

[0130] Specifically, the first nut assembly 1511 is in transmission connection with the drive shaft of the first drive motor 1513, and the second nut assembly 1521 is in transmission connection with the drive shaft of the second drive motor 1523. Threads are formed at positions near the other ends of the two first moving rods 1512 and the two second moving rods 1522. The other end of the first moving rod 1512 is in threaded connection with the first nut assembly 1511; the other end of the second moving rod 1522 is in threaded connection with the second nut assembly 1521; and the threads on the two first moving rods 1512 are opposite, and the threads on the two second moving rods 1522 are opposite.

[0131] Based on the above structure, since the two first moving rods 1512 and the two second moving rods 1522 are respectively in threaded connection with the first nut assembly 1511 and the second nut assembly 1521, and the thread directions are opposite, when the drive motor rotates, the two moving rods will move synchronously but in opposite directions. This design ensures that the main welding component and the auxiliary welding component can accurately and synchronously adjust their positions during the welding process. The synchronous and reverse moving mode helps to reduce the errors caused by mechanical vibration or imbalance and can improve the stability of the welding process.

[0132] Further, the design of using threaded connection and synchronous reverse movement can reduce the welding position deviation caused by mechanical errors or improper manual operation, and improve the overall consistency and aesthetics of the product.

[0133] Further, in the handle fixing device of the handbag provided by the present utility model, both the first nut assembly 1511 and the second nut assembly 1521 include a nut sleeve 1501 and a belt member 1502.

[0134] Specifically, the nut sleeve 1501 is coaxially arranged with the first moving rod 1512 and / or the second moving rod 1522, and the power output end of the belt member 1502 is drivingly connected to the nut sleeve 1501, and the power input end of the belt member 1502 is drivingly connected to the drive shaft of the first driving motor 1513 or the second driving motor 1523.

[0135] It should be understood that a belt member 1502 is provided at the drive shaft end of each driving component. The input wheel of the belt member 1502 is coaxially connected to the drive shaft of the driving component, and the output wheel of the belt member 1502 is integrally formed with the nut sleeve 1501, or the inner thread can be provided inside the output wheel of the belt member 1502 to serve as the nut sleeve 1501.

[0136] During implementation, the nut sleeve 1501 located at the first driving component 151 is coaxially arranged and threadedly connected to the first moving rod 1512, and the nut sleeve 1501 located at the second driving component 152 is coaxially arranged and threadedly connected to the second moving rod 1522.

[0137] Based on the above structure, the belt member 1502, as an intermediate component for power transmission, can stably transmit the power of the driving motor to the nut sleeve 1501, thereby driving the movement of the moving rod. This design reduces the energy loss during power transmission, improves the efficiency of power transmission. The belt member 1502 has a certain elasticity and can absorb and relieve mechanical vibration to a certain extent, making the entire heat-sealing process smoother and reducing errors and damages caused by vibration.

[0138] Further, the nut sleeve 1501 is coaxially arranged with the first moving rod 1512 and / or the second moving rod 1522, ensuring the linearity and accuracy of power transmission, helping to reduce errors caused by offset or misalignment, and improving the accuracy of the heat-sealing position.

[0139] Further, in the handle fixing device of the handbag provided by the present utility model, please refer to Figure 4 , a rotating connection member 160 is provided at one end of the first moving rod 1512 and one end of the second moving rod 1522.

[0140] One end of the first moving rod 1512 is rotatably connected to the upper end of the first main welding member 111 or the upper end of the second main welding member 112 through a rotating connection member 160; one end of the second moving rod 1522 is rotatably connected to the upper end of the first auxiliary welding member 121 or the upper end of the second auxiliary welding member 122 through a rotating connection member 160.

[0141] It should be understood that the first moving rod 1512 on one side of the first main welding member 111 and the first main welding member 111 are connected through the rotating connection member 160, the first moving rod 1512 on one side of the second main welding member 112 and the second main welding member 112 are connected through the rotating connection member 160, the second moving rod 1522 on one side of the first auxiliary welding member 121 and the first auxiliary welding member 121 are connected through the rotating connection member 160, and the second moving rod 1522 on one side of the second auxiliary welding member 122 and the second auxiliary welding member 122 are connected through the rotating connection member 160.

[0142] Please refer to Figure 4 , the structure of the rotating connection member 160 is not limited. For example, it can be a turntable, a hinge joint, etc.

[0143] Based on the above structure, the rotating connection member 160 allows the welding member to make a certain angle adjustment while moving. By adjusting the angle of the welding member, the welding error caused by the irregular shape or size deviation of the base material can be reduced, and the accuracy of the handle fixing can be improved. And the rotating connection member 160 can provide a stable support point for the welding member, so that the welding member can maintain a stable posture during the welding process, and reduce the position deviation caused by vibration or impact.

[0144] Furthermore, in the handle fixing device of the handbag provided by the present utility model, both the first main welding member 111 and the second main welding member 112 are set as heat welding members, and both the first auxiliary welding member 121 and the second auxiliary welding member 122 are set as ultrasonic generating members.

[0145] It should be understood that the structure of the heat welding member is not limited. For example, it can be an electric heater. The structure of the ultrasonic generating member is not limited. Specifically, a structure that converts industrial frequency alternating current into a high-frequency electrical oscillation signal (usually between 20 kHz and 100 kHz) is sufficient. The ultrasonic generator can internally include an oscillation circuit, a power amplification circuit, a matching circuit, etc. The present utility model does not introduce this in detail.

[0146] Based on the above structure, the first main heat-sealing member 111 and the second main heat-sealing member 112 melt and bond the handle and the handbag base material together at high temperature through heat-sealing. The use of heat-sealing technology can ensure sufficient contact and melting of the bonding surface, thereby forming a firm bonding layer and improving the strength and durability of the handle fixation. Moreover, the first auxiliary heat-sealing member 121 and the second auxiliary heat-sealing member 122 utilize the energy generated by ultrasonic vibration to generate microscopic friction and heat at the contact surface between the handle and the handbag base material, thereby achieving bonding. The ultrasonic bonding technology has the advantages of strong penetration, fast bonding speed, high bonding strength, etc., and can further enhance the firmness of the handle fixation.

[0147] Furthermore, since the heat-sealing member adopts the above structure, it is more conducive to controlling the temperature and time, and can achieve uniform bonding between the handle and the handbag base material, avoiding poor bonding or local overheating, which helps to improve the heat-sealing quality and make the handle fixation more flat and beautiful. And the ultrasonic bonding technology does not require additional adhesives, so it can avoid appearance problems caused by adhesive residues. At the same time, ultrasonic bonding can also reduce defects such as bubbles and cracks generated by heat-sealing, making the appearance of the handle fixation more perfect.

[0148] Furthermore, the use of the heat-sealing member and the ultrasonic generating member can also achieve rapid bonding of the handle, which helps to shorten the production cycle and improve production efficiency.

[0149] Even further, the ultrasonic bonding technology does not require additional heat sources and adhesives, so it can save energy and reduce pollution. And since less heat is generated during the bonding process, it also helps to reduce the temperature and humidity in the workshop and improve the working environment.

[0150] Furthermore, in the handle fixing device of the handbag provided by the present utility model, please refer to Figure 4 and Figure 5 , both the first main heat-sealing member 111 and the second main heat-sealing member 112 include a lifting cylinder 113 and a heat-sealing block 114 provided at the lower end of the lifting cylinder 113; both the first auxiliary heat-sealing member 121 and the second auxiliary heat-sealing member 122 include an ultrasonic generator and a forming block 123 provided at the top of the ultrasonic generator, and the heat-sealing block 114 is adapted to the forming block 123.

[0151] Specifically, the end of each forming block 123 includes a first forming area 1231 and a second forming area 1232 arranged in sequence along the direction of the base material conveyance. Among them, one of the first forming area 1231 and the second forming area 1232 is set as a planar structure, and the other is set as a concave-convex structure. Specifically, the first forming area 1231 can be set as a planar structure and the second forming area 1232 can be set as a concave-convex structure, or the first forming area 1231 can be set as a concave-convex structure and the second forming area 1232 can be set as a planar structure.

[0152] Based on the above structure, the matching design of the hot-melting block 114 and the forming block 123 ensures the precise alignment of the handle and the base material of the handbag during the hot-melting process, which can reduce the problem of poor hot-melting caused by position deviation and improve the accuracy of hot-melting.

[0153] Furthermore, the different structural designs (plane and concave-convex) of the first forming area 1231 and the second forming area 1232 can meet the requirements of handles with different shapes and structures. Among them, the plane structure is suitable for the hot-melting of simple straight lines, while the concave-convex structure can better adapt to handles with special shapes or structures, such as handles with grooves or protrusions.

[0154] Furthermore, through the lifting cylinder 113, the hot-melting block 114 can apply appropriate pressure to the contact surface between the handle and the base material of the handbag, ensuring the tight adhesion between the two, thereby improving the strength of hot-melting.

[0155] Moreover, based on the above structure, the device can also be adjusted according to different handle shapes and sizes. By replacing the forming block 123 with different shapes, it can meet the production requirements of various types of handbags and improve the flexibility of the equipment.

[0156] Furthermore, in the handle fixing device of the handbag provided by the present utility model, please refer to Figure 5 , the first main hot-melting member 111 and the second main hot-melting member 112 further include an installation table 115. The installation table is provided with a first installation position and a second installation position arranged in sequence along the conveying direction of the base material. The hot-melting block 114 is selectively connected to the first installation position or the second installation position.

[0157] Specifically, the installation table 115 is provided with a pressing plate 1151 and a connecting side plate 1152. The pressing plate 1151 is connected to the installation table 115 along the length direction of the installation table, and the connecting side plate 1152 is connected to the installation table 115 along the height direction of the installation table. The first installation position and the second installation position are located in the area formed by the connecting side plate 1152 and the pressing plate 1151, and the hot-melting block 114 is detachably connected to the connecting side plate. The hot-melting surface of the hot-melting block 114 is formed with an extrusion protrusion 1141 having a table-like structure.

[0158] Furthermore, a plurality of connecting holes are provided on both the pressing plate 1151 and the connecting side plate 1152. When the hot-melting block 114 needs to be connected to the first installation position, the hot-melting block 114 can be connected to the connecting holes in the first installation position by screws. Similarly, when the hot-melting block 114 needs to be connected to the second installation position, the hot-melting block 114 can be connected to the connecting holes in the second installation position by screws.

[0159] The number of connecting holes is not limited and can be set according to actual needs.

[0160] Based on the above structure, the first installation position and the second installation position arranged along the base material conveying direction on the installation table allow the heat-sealing block 114 to be selectively connected to different positions according to actual needs. This design increases the flexibility of the equipment, enabling the same set of equipment to adapt to handbag base materials of different sizes, shapes, or heat-sealing positions.

[0161] Furthermore, the detachable connection design between the heat-sealing block 114 and the connecting side plate makes the replacement and maintenance of the heat-sealing block 114 simple and fast. And when it is necessary to replace the heat-sealing block 114 of a different shape or size, it is only necessary to disconnect the current heat-sealing block 114 and install the new heat-sealing block 114, without the need for large-scale adjustment of the entire equipment. The table-like structure extrusion protrusion 1141 formed on the heat-sealing surface of the heat-sealing block 114 can generate greater pressure during the heat-sealing process, and can make the heat-sealing force more evenly distributed on the contact surface between the handle and the handbag base material, avoiding heat-sealing quality problems caused by excessive or too little local stress, and contributing to the tight bonding between the handle and the handbag base material. This design improves the strength and stability of heat-sealing and reduces the problem of handle detachment caused by insecure bonding.
