Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, and in particular to a hot-iron handle device for packaging bags. Background Technology

[0002] During the production of packaging bags, it is often necessary to weld the two ends of the handle to the bag body at the opening using ultrasonic welding equipment so that users can carry and use it.

[0003] In existing technology, packaging bag processing equipment typically includes a winding roller for winding the substrate, a forming device for initially shaping the bag, and a cutting device. During packaging bag production, this equipment uses two heat-sealing devices sequentially installed beside the transport bag carrying the substrate. The sides of the substrate are welded to the handle material via an ultrasonic welding mechanism within the heat-sealing device. As the substrate continues to move forward, the next handle is welded. Alternatively, a pair of heat-sealing devices are installed beside the transport bag carrying the substrate to fix the handle to the substrate. In other words, the handle of the packaging bag requires at least two processes, and even more processes for special packaging bags (with three or more handles), significantly impacting production efficiency. Furthermore, multiple separately installed heat-sealing devices increase the space occupied by the packaging bag processing equipment, making its layout inconvenient. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems in the prior art where packaging bag processing equipment requires two or more processes to process the handles of packaging bags, which greatly affects the production efficiency of packaging bags; and where multiple separately set ironing handle devices increase the space occupied by the packaging bag processing equipment and are inconvenient for the layout of the packaging bag processing equipment.

[0005] To solve the above-mentioned technical problems, the present invention discloses a hot-pressing device for packaging bags. The hot-pressing device includes a frame, a material storage component for storing handle material disposed on the frame, and at least two hot-pressing components spaced apart along the width direction of the frame.

[0006] Each heat-sealing component includes a pair of heat-sealing heads arranged along the width direction. The frame is also provided with at least two pairs of welding heads located below the heat-sealing components in the height direction of the frame, corresponding to each heat-sealing component. Each heat-sealing component can move along the height direction toward the corresponding pair of welding heads.

[0007] Furthermore, a component spacing adjustment component is provided between any two adjacent heat-sealing components, which can adjust the spacing between the two adjacent heat-sealing components in the width direction; and an end spacing adjustment component is provided between a pair of heat-sealing heads of each heat-sealing component, which can adjust the spacing between the pair of heat-sealing heads in the width direction.

[0008] The component spacing adjustment component adjusts the spacing between two adjacent heat-sealing components to a first predetermined width between two handles, and the end spacing adjustment component adjusts the spacing between a pair of heat-sealing heads to a second predetermined width between the two ends of a corresponding handle. Handle material from the storage component is conveyed to a predetermined position on a substrate conveyed along the length of the frame. A pair of heat-sealing heads of each heat-sealing component moves toward the welding head to fix the end of the handle material to the predetermined position on the substrate.

[0009] Using the above technical solution, this hot-pressing device includes at least two hot-pressing components, which can simultaneously fix at least two handles on the substrate, greatly improving the production efficiency of packaging bags. Furthermore, since this hot-pressing device integrates at least two hot-pressing components together, it can fix multiple handles at the same time, eliminating the need to set up multiple hot-pressing devices in the packaging bag processing equipment. This makes the structure of the packaging bag processing equipment more compact, reduces the space occupied by the packaging bag processing equipment, and is suitable for the layout of small and medium-sized production workshops.

[0010] Furthermore, this ironing device features a component spacing adjustment assembly between any two adjacent ironing components, and an end spacing adjustment assembly between a pair of ironing heads in each ironing component. This ironing device achieves two-stage adjustment through these component and end spacing adjustment assemblies. Specifically, the component spacing adjustment assembly accommodates the different bag body requirements for handle installation positions. For example, when the base material of the bag body is wide, the distance between two adjacent handles on the base material is larger. Further, the end spacing adjustment assembly accommodates the installation requirements of handles of different sizes. For example, when the handle is long, the distance between the two ends of the handle is larger when fixed to the base material. Therefore, this ironing device can adapt to various bag specifications and handle sizes. Moreover, adjusting two adjacent pairs of ironing heads does not affect the distance between each pair of ironing heads; similarly, adjusting one pair of ironing heads does not affect the distance between two adjacent pairs of ironing heads, ensuring accurate adjustment of the position of each ironing head.

[0011] Furthermore, an embodiment of this utility model also discloses an ironing device for packaging bags, wherein the component spacing adjustment component between two adjacent ironing components includes a first spacing adjustment drive component.

[0012] Each heat-sealing assembly also includes a mounting plate, a pair of heat-sealing heads are movably mounted on one side of the mounting plate, and the mounting plate is movably mounted on the first guide member of the frame.

[0013] Furthermore, the mounting plate of at least one of the two adjacent hot-pressing components is connected to the first adjustment drive component, which drives the mounting plate to move along the first guide member.

[0014] Using the above technical solution, the first guide component set on the frame can guide the adjustment of the heat-sealing component, preventing the heat-sealing component from shifting in other directions during the adjustment process, while the first adjustment drive component can drive the mounting plate to move.

[0015] Regarding the method by which the first adjustment drive component drives the adjustment of the distance between two adjacent heat-sealing components, one heat-sealing component can be driven by the first adjustment drive component to move towards or away from the other heat-sealing component along the first guide, while the other heat-sealing component remains stationary.

[0016] Specifically, the first pitch-adjusting drive component includes a first drive motor and a first transmission component connecting the first drive motor and a corresponding mounting plate.

[0017] In one embodiment, the output end of the first drive motor is connected to the first transmission member, the first transmission member has a transmission part, and one transmission part of the first transmission member is connected to the mounting plate of one of the hot-pressing components. The first drive motor drives the first transmission member and moves one of the hot-pressing components toward or away from the other hot-pressing component.

[0018] Using the above technical solution, the mounting plate of the heat-sealing component driven by the first drive motor moves along the first guide member, thereby adjusting the distance between two adjacent heat-sealing components, while the other fixed heat-sealing component plays a positioning role.

[0019] Of course, in another alternative implementation, the two heat-sealing components can be driven to move toward or away from each other along the first guide by the first adjusting component.

[0020] Specifically, in one embodiment, the first adjustment drive component can be configured as a first drive motor, the first transmission component has two transmission parts, the mounting plates of two adjacent hot-pressing components are respectively connected to the first transmission component through the two transmission parts, and a first drive motor drives the first transmission component and links the two hot-pressing components to move towards or away from each other.

[0021] Using the above technical solution, both heat-sealing components are driven by the first motor and move towards or away from each other along the first guide. Therefore, this component spacing adjustment component is more compact in structure while ensuring that the two heat-sealing components can be driven to move simultaneously. Furthermore, since the mounting plates of the two heat-sealing components are respectively connected to the two transmission parts on the first transmission member, the movement between the mounting plates of the two heat-sealing components is related to each other and has synchronicity.

[0022] In another embodiment, the first adjustment drive component is configured as two first drive motors, which correspond to two adjacent hot stamping components. A first transmission member is provided between the output end of each first drive motor and the mounting plate of the corresponding hot stamping component. The first transmission member has a transmission part, and one transmission part of the first transmission member is connected to the mounting plate of the corresponding hot stamping component. The first drive motor drives the first transmission member and moves the corresponding hot stamping component along the first guide member.

[0023] With the above technical solution, the two heat-sealing components move independently along the first guide. Even if one of the first drive motors or the mounting plate of the heat-sealing component fails with the first guide, the mounting plate of the other heat-sealing component can be driven to move along the first guide by the other first motor, thereby ensuring the adjustment of the spacing between the two adjacent heat-sealing components.

[0024] In summary, in this embodiment, the specific structure of the component adjustment component is not uniquely limited by this utility model.

[0025] Furthermore, an embodiment of this utility model also discloses a hot ironing device for packaging bags, wherein the end adjustment component includes a second guide member disposed on a mounting plate and a second adjustment drive member between a pair of hot ironing heads.

[0026] The second guide extends along the width direction and is fixedly disposed on the side surface of the mounting plate near the pair of hot stamping heads. The ends of the pair of hot stamping heads are respectively disposed on the second guide, and at least one of the pair of hot stamping heads is connected to the second adjustment drive component to drive the corresponding hot stamping head to move along the second guide.

[0027] It should be noted that the structure of the end spacing adjustment component for adjusting the distance between a pair of heat-sealing heads is similar to the structure of the component spacing adjustment component for adjusting the distance between two adjacent heat-sealing components.

[0028] Furthermore, this ironing device also includes a third guide member extending along the width direction on the frame, and at least two third adjustment drive components. The base of each pair of welding heads is movably mounted on the third guide member and is connected to the corresponding third adjustment drive component. The third adjustment drive component drives the base to move along the third guide member so that the base corresponds to the mounting plate on which the corresponding pair of ironing heads are mounted in the height direction.

[0029] A welding head adjustment assembly is provided between a pair of welding heads. The welding head adjustment assembly includes a fourth guide member disposed on the base and a fourth adjustment drive member between the pair of welding heads. The fourth guide member extends along the width direction and is fixedly connected to one side surface of the base. The ends of the pair of welding heads are respectively movably disposed on the fourth guide member, and at least one of the pair of welding heads is drivenly connected to the fourth adjustment drive member. The fourth adjustment drive member drives at least one welding head to move along the fourth guide member so that the pair of welding heads corresponds to the corresponding pair of hot stamping heads in the height direction.

[0030] Using the above technical solution, the base is driven to move along the third guide by the third adjustment drive component, so that the base corresponds to the mounting plate with a pair of corresponding hot-pressing heads in the height direction. The fourth adjustment drive component drives at least one of the pair of welding heads, so that the pair of welding heads corresponds to the pair of corresponding hot-pressing heads in the height direction, thereby precisely controlling the position of each welding head, so that the hot-pressing heads and the corresponding welding heads can be precisely pressed together, realizing the connection between the handle end and the substrate.

[0053] As noted in the background section, in the prior art, packaging bag processing equipment requires two or more processes to process the handles of packaging bags, which greatly affects the production efficiency of packaging bags; in addition, multiple separately set ironing handle devices increase the space occupied by the packaging bag processing equipment and are inconvenient for the layout of the packaging bag processing equipment.

[0054] Therefore, this utility model provides a hot-pressing device for packaging bags. This hot-pressing device includes a frame, a material storage component for storing handle material disposed on the frame, and at least two hot-pressing components spaced apart along the width direction of the frame. Each hot-pressing component includes a pair of hot-pressing heads. The frame is also provided with at least two pairs of welding heads located below the hot-pressing components. Each hot-pressing component can move along the height direction toward the corresponding pair of welding heads. This hot-pressing device integrates at least two hot-pressing components together, which can fix multiple handles at the same time. It eliminates the need to set multiple hot-pressing devices in the packaging bag processing equipment, making the structure of the packaging bag processing equipment more compact.

[0055] Furthermore, in order to adapt to various bag sizes and handle sizes, a component spacing adjustment component is provided between any two adjacent heat-sealing components. The component spacing adjustment component can adjust the distance between two adjacent heat-sealing components. An end spacing adjustment component is provided between a pair of heat-sealing heads of each heat-sealing component. The end spacing adjustment component can adjust the distance between a pair of heat-sealing heads.

[0056] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0057] like Figure 1 As shown, an embodiment of this utility model discloses a hot-pressing device 10 for packaging bags. This hot-pressing device 10 includes a frame 100 and a storage assembly 101 for storing handle material disposed on the frame 100 (see [link]). Figure 8 ), along the width direction of frame 100 ( Figure 1 At least two heat-sealing components 200 are spaced apart in the horizontal direction. Each heat-sealing component 200 includes a pair of heat-sealing heads 210 arranged in the width direction. The frame 100 is also provided with at least two pairs of welding heads 220 located below the heat-sealing components 200 in the height direction of the frame 100 and corresponding to each heat-sealing component 200. Each heat-sealing component 200 can be arranged in the height direction ( Figure 1 The vertical direction of the welding head 220 moves towards the corresponding pair of welding heads 220.

[0058] Furthermore, a component spacing adjustment component 300 is provided between any two adjacent heat-sealing components 200, which can adjust the spacing between the two adjacent heat-sealing components 200 in the width direction; and an end spacing adjustment component 400 is provided between a pair of heat-sealing heads 210 of each heat-sealing component 200, which can adjust the spacing between the pair of heat-sealing heads 210 in the width direction.

[0059] It should be noted that the component spacing adjustment component 300 is an independent component used to adjust the spacing between two adjacent (hot stamping) components 300.

[0060] like Figure 1 and Figure 2 As shown, the component spacing component 300 adjusts the spacing between two adjacent heat-sealing components 200 to a first predetermined width X1 between two adjacent handles, and the end spacing component 400 adjusts the spacing between a pair of heat-sealing heads 210 to a second predetermined width X2 between the two ends of a corresponding handle. The handle material from the material storage component 101 is conveyed to a predetermined position on the substrate 20 conveyed along the length direction of the frame 100. The pair of heat-sealing heads 210 of each heat-sealing component 200 moves toward the welding head 220 to fix the end of the handle material to the predetermined position of the substrate 20.

[0061] This hot-pressing device 10 includes at least two hot-pressing components 200, which can simultaneously fix at least two handles on the substrate, greatly improving the production efficiency of packaging bags. Furthermore, since this hot-pressing device 10 integrates at least two hot-pressing components 200 together, it can fix multiple handles at the same time, eliminating the need to set up multiple hot-pressing devices 10 in the packaging bag processing equipment. This makes the structure of the packaging bag processing equipment more compact, reduces the space occupied by the packaging bag processing equipment, and is suitable for the layout of small and medium-sized production workshops.

[0062] Furthermore, a component spacing adjustment component 300 is provided between any two adjacent ironing components 200 of this ironing device 10, and an end spacing adjustment component 400 is provided between a pair of ironing heads 210 of each ironing component 200. This ironing device 10 achieves two-stage adjustment through the component spacing adjustment component 300 and the end spacing adjustment component 400. Specifically, by setting the component spacing adjustment component 300, the requirements of different bag bodies for the installation position of the handles are met. For example, when the base material of the bag body is wider, the distance between two adjacent handles on the base material is larger. Furthermore, by setting the end spacing adjustment component 400, the installation requirements of handles of different sizes are met. For example, when the handle is longer, the distance between the two ends of the handle is larger when it is fixed to the base material. Therefore, this ironing device 10 can be adapted to various sizes of bag bodies and handles of different sizes. Furthermore, adjusting two adjacent pairs of ironing heads 210 will not affect the spacing between each pair of ironing heads 210. Similarly, adjusting one pair of ironing heads 210 will not affect the spacing between two adjacent pairs of ironing heads 210, ensuring that the position of each ironing head 210 can be accurately adjusted.

[0063] Regarding the base material and handle material of the hot-pressing device 10, i.e. the material of the packaging bag, it can be non-woven fabric, plastic or other materials that can be connected by high-temperature hot pressing. This embodiment does not make specific limitations on this.

[0064] Among them, such as Figure 2 As shown, the first predetermined width X1 between two adjacent handles 30 can be 25 cm, 30 cm or 40 cm, depending on the bag body; while the second predetermined width X2 between the two ends of the handle 30 can be 8 cm, 10 cm or 15 cm, depending on the size of the handle.

[0065] It should be noted that two, three, or four heat-sealing components 200 may be spaced apart along the width of the frame 100, depending on the actual situation, i.e., the number of handles to be fixed on the substrate. This embodiment does not impose a specific limitation on this. For ease of explanation, two heat-sealing components 200 will be used as an example below.

[0066] Furthermore, embodiments of this utility model also disclose an ironing device 10 for packaging bags, such as... Figure 1 and Figure 3 As shown, the component spacing adjustment component 300 between two adjacent hot stamping components 200 includes a first spacing adjustment drive component 310.

[0067] Each heat-sealing assembly 200 also includes a mounting plate 230, and a pair of heat-sealing heads 210 are movably disposed on one side of the mounting plate 230. The mounting plate 230 is movably disposed on the first guide member 110 of the frame 100. It should be noted that each heat-sealing head 210 includes a pressure-driving motor and a pressure end disposed vertically at the lower end of the pressure-driving motor. The pressure-driving motor can drive the pressure end to move vertically, and the upper end of the pressure-driving motor is connected to the mounting plate 230. Of course, this embodiment does not specifically limit the specific structure of the heat-sealing head 210.

[0068] Furthermore, the mounting plate 230 of at least one of the two adjacent hot-pressing components 200 is connected to the first adjustment drive component 310, and the first adjustment drive component 310 drives the mounting plate 230 to move along the first guide member 110.

[0069] Specifically, the first guide member 110 is a first guide rail 111 extending along the width direction on the frame 100, and the mounting plate 230 of the heat-sealing assembly 200 is slidably connected to the first guide rail 111 via a first slider 231 disposed on the mounting plate 230. Of course, the first guide member 110 can be a guide groove or guide rod or other structures that can play a guiding role, and this embodiment does not specifically limit it.

[0070] In this embodiment, the first guide member 110 disposed on the frame 100 can guide the adjustment of the heat-pressing assembly 200, preventing the heat-pressing assembly 200 from shifting in other directions during the adjustment process, while the first adjustment driving component 310 can drive the mounting plate 230 to move.

[0071] More specifically, in this embodiment, the first guide member 110 includes two first guide rails 111 spaced apart along the length of the frame 100. The two first guide rails 111 not only guide the mounting plate 230, but also support the mounting plate 230.

[0072] Regarding the method by which the first distance adjustment drive component 310 drives the distance adjustment between two adjacent heat-sealing components 200, one heat-sealing component 200 can be driven to move along the first guide 110 toward or away from the other heat-sealing component 200, while the other heat-sealing component 200 remains stationary.

[0073] Specifically, such as Figure 3 As shown, the first pitch-adjusting drive component 310 includes a first drive motor 311 and a first transmission component 312 connecting the first drive motor 311 and the corresponding mounting plate 230.

[0074] In one embodiment, the output end of the first drive motor 311 is connected to the first transmission member 312. The first transmission member 312 has a transmission part 313. One transmission part 313 is connected to the mounting plate 230 of one of the hot-pressing components 200. The first drive motor 311 drives the first transmission member 312 and moves one of the hot-pressing components 200 toward or away from the other hot-pressing component 200.

[0075] In this embodiment, the mounting plate 230 of the heat-sealing component 200, which is driven to move by the first drive motor 311, moves along the first guide member 110, thereby adjusting the distance between two adjacent heat-sealing components 200, while the other heat-sealing component 200, which is fixed, plays a positioning role.

[0076] Of course, in another alternative embodiment, the two heat-sealing components 200 may be moved toward or away from each other along the first guide 110 by the first adjusting component.

[0077] Specifically, in one embodiment, the first adjustment drive component 310 can be configured as a first drive motor 311, and the first transmission component 312 has two transmission parts 313. The mounting plates 230 of two adjacent hot-pressing components 200 are respectively connected to the first transmission component 312 through the two transmission parts 313. The first drive motor 311 drives the first transmission component 312 and links the two hot-pressing components 200 to move towards or away from each other.

[0078] In this embodiment, both heat-sealing components 200 are driven by the first motor and move towards or away from each other along the first guide member 110. Therefore, this component spacing adjustment component 300 has a more compact structure while ensuring that the two heat-sealing components 200 are driven to move simultaneously. Furthermore, since the mounting plates 230 of the two heat-sealing components 200 are respectively connected to the two transmission parts 313 on the first transmission member 312, the movement between the mounting plates 230 of the two heat-sealing components 200 is related to each other and has synchronicity.

[0079] In another embodiment, the first adjustment drive component 310 is configured as two first drive motors 311, which correspond to two adjacent hot stamping components 200. The output end of each first drive motor 311 is provided with a first transmission member 312 between it and the mounting plate 230 of the corresponding hot stamping component 200. The first transmission member 312 has a transmission part 313, and one transmission part 313 of the first transmission member 312 is connected to the mounting plate 230 of the corresponding hot stamping component 200. The first drive motor 311 drives the first transmission member 312 and moves the corresponding hot stamping component 200 along the first guide member 110.

[0080] In this embodiment, the mounting plates 230 of the two heat-sealing components 200 are driven by corresponding first motors and move along the first guide 110, thereby realizing the adjustment of the spacing between the two adjacent heat-sealing components 200. That is, the two heat-sealing components 200 move independently along the first guide 110. Even if one of the first drive motors 311 or the mounting plate 230 of the heat-sealing component 200 fails with the first guide 110, the mounting plate 230 of the other heat-sealing component 200 can be driven by the other first motor to move along the first guide 110, thereby ensuring the adjustment of the spacing between the two adjacent heat-sealing components 200.

[0081] In summary, in this embodiment, the specific structure of the component adjustment component 300 is not limited to a single one.

[0082] The first transmission component 312 between the first drive motor 311 and the mounting plate 230 will be described in detail below.

[0083] In one embodiment, the first transmission member 312 is configured as a first lead screw 314, and the output end of the first drive motor 311 can drive the first lead screw 314 to rotate in a transmission connection with the first lead screw 314.

[0084] Specifically, such as Figure 3 As shown, the output end of the first drive motor 311 extends along the width direction. In order to drive the rotation along the first lead screw 314, the output end of the first drive motor 311 is connected to the first lead screw 314 via a belt. Of course, the output end of the first drive motor 311 can also be directly connected to the first lead screw 314.

[0085] Specifically, such as Figure 3 As shown, when the first lead screw 314 has a transmission part 313 and the transmission part 313 is a hinge part 315 provided at the end of the first lead screw 314, the first drive motor 311 is fixed on the frame 100, the first lead screw 314 is movably connected to the drive motor in the width direction, and the end of the mounting plate 230 is hinged to the end of the first lead screw 314 in a way that allows rotation about the height direction.

[0086] In another embodiment, when the first lead screw 314 has a transmission part 313 and the transmission part 313 is an external thread provided on the outer periphery of the first lead screw 314, the first drive motor 311 and the first lead screw 314 are fixedly mounted on the frame 100, and the end of the mounting plate 230 is connected to the first lead screw 314 through an internal thread adapted to the transmission part 313.

[0087] When the first lead screw 314 is provided with two transmission parts 313, and the transmission parts 313 are external threads provided on the outer periphery of the first lead screw 314, the first drive motor 311 and the first lead screw 314 are fixedly mounted on the frame 100. The two transmission parts 313 are two sets of external threads that are spaced apart along the length direction of the first lead screw 314 and have opposite directions of rotation. The ends of the mounting plates 230 of the two adjacent hot-pressing components 200 are respectively connected to the first lead screw 314 through internal threads that are adapted to the corresponding transmission parts 313.

[0088] It should be noted that the first transmission component 312 between the first drive motor 311 and the mounting plate 230 is not limited to a lead screw structure, but can also be a transmission belt. The transmission belt extends along the width direction of the frame 100, that is, parallel to the extension direction of the first guide rail 111. The output end of the first drive motor 311 extends along the length direction of the frame 100. The first drive motor 311 can move along the width direction of the frame in conjunction with the transmission belt. The transmission part 313 on the transmission belt is set as a connecting plate fixedly connected to the mounting plate 230. When the transmission belt moves, the mounting plate 230 is moved through the connecting plate.

[0089] Furthermore, embodiments of this utility model also disclose an ironing device 10 for packaging bags, such as... Figure 3 As shown, the end spacing adjustment assembly 400 includes a second guide 232 disposed on the mounting plate 230 and a second spacing adjustment drive component 410 between a pair of heat pressing heads 210.

[0090] The second guide member 232 extends along the width direction and is fixedly disposed on the side surface of the mounting plate 230 near the pair of hot stamping heads 210. The ends of the pair of hot stamping heads 210 are respectively disposed on the second guide member 232, and at least one of the pair of hot stamping heads 210 is connected to the second adjustment drive component 410 to drive the corresponding hot stamping head 210 to move along the second guide member 232.

[0091] In one embodiment, the second guide member 232 is a second guide rail 233, and the end of each heat pressing head 210 is slidably connected to the second guide rail 233 via a second slider 211; the second adjustment drive component 410 is configured as a second drive motor 411, and a second lead screw 412 extending in the width direction is disposed between the second drive motor 411 and one of the pair of heat pressing heads 210, the output end of the second drive motor 411 is connected to the second lead screw 412 for transmission, and one end of the second lead screw 412 is connected to the corresponding heat pressing head 210.

[0092] It should be noted that the structure of the end-split adjustment assembly 400 for adjusting the distance between a pair of pressing heads 210 is similar to the structure of the component-split adjustment assembly 300 for adjusting the distance between two adjacent pressing components 200. That is, the second lead screw 412, which is located between the second drive motor 411 and one of the pressing heads 210, can also have a hinge at its end, allowing the pressing head 210 to be rotatably hinged to it about its height; alternatively, the second lead screw 412 can have an external thread on its outer circumference, and the pressing head 210 can be connected to the first lead screw 314 via an internal thread adapted to the transmission part; when the second lead screw 412 is connected to both pressing heads 210, the second lead screw 412 has two sets of external threads spaced apart along its length and rotating in opposite directions, and the pressing heads 210 are respectively connected to the first lead screw 314 via internal threads adapted to their respective transmission parts. Of course, the second drive motor 411 and the pressing head 210 can also be connected via a drive belt.

[0093] Furthermore, such as Figure 4 As shown, this ironing device 10 also includes a third guide 120 extending in the width direction on the frame 100, and at least two third adjustment drive components 130. The base 240 of each pair of welding heads 220 is movably disposed on the third guide 120 and is connected to the corresponding third adjustment drive component 130. The third adjustment drive component 130 drives the base 240 to move along the third guide 120, so that the base 240 corresponds to the mounting plate 230 on which the corresponding pair of ironing heads 210 are disposed in the height direction.

[0094] like Figure 4 As shown, a welding head spacing adjustment assembly 500 is provided between a pair of welding heads 220. The welding head spacing adjustment assembly 500 includes a fourth guide member 241 disposed on a base 240 and a fourth spacing adjustment drive member 510 between the pair of welding heads 220. The fourth guide member 241 extends along the width direction and is fixedly connected to one side surface of the base 240. The ends of the pair of welding heads 220 are respectively movably disposed on the fourth guide member 241, and at least one of the pair of welding heads 220 is drivenly connected to the fourth spacing adjustment drive member 510. The fourth spacing adjustment drive member 510 drives at least one welding head 220 to move along the fourth guide member 241, so that the pair of welding heads 220 correspond to the corresponding pair of hot stamping heads 210 in the height direction.

[0095] In this embodiment, the third adjustment drive component 130 drives the base 240 to move along the third guide 120 so that the base 240 corresponds to the mounting plate 230 with a corresponding pair of hot stamping heads 210 in the height direction. The fourth adjustment drive component 510 drives at least one of the pair of welding heads 220 so that the pair of welding heads 220 corresponds to the corresponding pair of hot stamping heads 210 in the height direction, thereby precisely controlling the position of each welding head 220 so that the hot stamping heads 210 and the corresponding welding heads 220 can be precisely pressed together to achieve the connection between the handle end and the substrate.

[0096] Specifically, in one embodiment, the third guide member 120 is a third guide rail 121 that is disposed on the frame 100 and extends in the width direction, and each third pitch adjustment drive component 130 includes a third drive motor 131 and a third transmission component 132 disposed between the third drive motor 131 and the corresponding base 240.

[0097] The fourth guide member 241 is a fourth guide rail 242 that is disposed on the base 240 and extends in the width direction. Furthermore, each fourth pitch adjustment drive component 510 includes a fourth drive motor 511 and a fourth transmission member 512 disposed between the fourth drive motor 511 and the corresponding welding head 220.

[0098] In one embodiment, such as Figure 4 As shown, the third transmission component 132 is a third lead screw 133 extending along the width direction, and the fourth transmission component 512 is a fourth lead screw 513 extending along the width direction.

[0099] It should be noted that the third distance adjustment drive component 130, which adjusts the distance between the bases 240 of two adjacent heat-sealing components 200, has a similar structure to the first distance adjustment drive component 310, which adjusts the distance between the mounting plates 230 of two adjacent heat-sealing components 200; the welding head distance adjustment component 500, which adjusts the distance between a pair of welding heads 220, has a similar structure to the end adjustment tool component, which adjusts the distance between a pair of heat-sealing pressure heads 210, and will not be described in detail here.

[0100] Of course, in another alternative embodiment, each welding head 220 is longer than the corresponding hot stamping head 210 in the width direction. In this case, there is no need to adjust the position of the welding head 220 in the width direction. Even if the position of the hot stamping head 210 in the width direction is changed, it can still be pressed on the upper surface of the welding head 220 when the hot stamping head 210 moves toward the welding head 220 in the height direction.

[0101] It should be noted that, in order to facilitate the supply of handle material, in one embodiment, such as Figure 1 and Figure 5This hot ironing device 10 also includes a feeding assembly 600 and a cutting assembly 700 disposed on the frame 100 and located between the material storage assembly 101 and the hot ironing assembly 200.

[0102] like Figure 5 and Figure 6 As shown, the feeding assembly 600 has a feeding channel for conveying handle material, a feeding guide rail (not shown) extending along the width direction of the frame 100, and a pressure plate 610 movably disposed on the feeding guide rail, and the feeding channel passes through the cutter assembly 700.

[0103] The pressure plate 610 is located above the feeding channel and can move along the height direction. The handle material in the storage component 101 enters the feeding channel. The pressure plate 610 moves towards the handle material along the height direction until the handle material is clamped. The pressure plate 610 moves along the feeding guide and moves the handle material along the feeding channel in conjunction with it. The cutter component 700 cuts the handle material in the feeding channel into a handle of a predetermined length.

[0104] Of course, in addition to the above-mentioned method of feeding the handle material by means of the pressure plate 610, the handle material can also be moved along the width direction of the frame 100 by means of clamping the clamp plate. This embodiment does not limit this to the only method.

[0105] like Figure 7 As shown, the cutting assembly 700 may include a blade holder 710, a blade 720 disposed on the blade holder 710, and a blade driving component 730 for driving the blade 720 to cut. The blade driving component 730 may be a drive cylinder or motor commonly used in the art, and this embodiment does not specifically limit it.

[0106] It should be noted that, since the lifting handle is fixed to the substrate, it needs to be bent into a "U" shape for easy gripping (see...). Figure 2 Therefore, such as Figure 5 As shown, the heat-sealing assembly 200 also includes a handle component 250, which is movably mounted on the frame 100. The handle material in the storage assembly 101 is conveyed to a predetermined position on the substrate by the feeding assembly 600. The cutting assembly 700 cuts the handle material to a predetermined length, and the handle component 250 compresses the cut handle into a predetermined length, causing the handle to bend into a "U" shape.

[0107] Specifically, in one embodiment, the handle component 250 includes a handle guide rail 140 disposed on the frame 100 and extending in the width direction, and a pair of handle members 251 movably disposed on the handle guide rail 140.

[0108] Each handle 251 includes a clamping part 252 that can move in the height direction, and a rotating part 253 located below the clamping part 252 and rotatable about the height direction.

[0109] The cutting blade assembly 700 cuts to a predetermined length to form a lifting handle. A pair of rotating handle members 251 are located on both sides of the lifting handle in the width direction, and the lifting handle is located between the clamping part 252 and the rotating part 253. The clamping part 252 moves toward the rotating part 253 to clamp the lifting handle. The pair of rotating handle members 251 move toward each other along the rotating handle guide 140, and the rotating parts 253 of the pair of rotating handle members 251 rotate toward each other until the distance between the pair of rotating handle members 251 in the width direction is equal to the distance between the pair of pressing heads 210, and the two ends of the lifting handle are respectively located below the pair of pressing heads 210. The length of the lifting handle can be 15 cm, 20 cm, 27 cm or other lengths, depending on the length of the handle design. This embodiment does not specifically limit this.

[0110] Furthermore, it should be noted that the blade holder 710 of the cutter assembly 700 is slidably mounted on the handle guide rail 140. Those skilled in the art can adjust the position of the cutter assembly 700 on the handle guide rail 140 according to actual conditions and specific needs. This embodiment does not impose any specific limitations on this.

[0111] Of course, this embodiment does not limit the specific structure of the handle component 250.

[0112] Furthermore, the material storage component 101 can be a take-up roller for storing handle material. In one embodiment, each heat-sealing component 200 corresponds to one material storage component 101, such as... Figure 7 As shown, the frame 100 of this hot-pressing device 10 has a material storage component 101 on each side of the width direction, which supplies handle material to the two hot-pressing components 200 respectively. Of course, in another alternative embodiment, the hot-pressing device 10 includes a material storage component 101, which supplies handle material to at least two hot-pressing components 200. A cutting component 700 is provided on both sides of the width direction of each hot-pressing component 200 to cut the handle material into handles of a predetermined length. This embodiment is not limited to this.
