Description

Technical Field

[0001] The present application relates to the field of belt skirt processing, and in particular to a high-frequency welding die for automatically bypassing the belt skirt processing. Background Art

[0002] Adding skirts on both sides of the conveyor belt can prevent the product from scattering when climbing a slope, effectively solving the trouble caused by site restrictions or the need to lift materials at a large angle.

[0003] When welding the skirts on both sides of the belt (conveyor belt), the skirts are usually crimped into the mold manually, and then the mold containing the skirts is placed on the belt, and the specific position between the mold and the belt is manually corrected. The skirts in the mold are hot-melt welded to the placed belt through a heating device, and then the mold is manually demolded after welding. The operation is cumbersome and reduces production efficiency.

[0004] In the prior art, there is a belt skirt processing device disclosed in publication number CN117103712B, which includes a workbench fixed to the ground and a high-frequency plastic welding machine fixed to the workbench. The workbench is also movably connected with a clamp for clamping the skirt, and the clamp is located above the position for placing the belt. The clamp consists of a front mold and a rear mold. The workbench is provided with a driving member for driving the front mold and the rear mold to move in a direction close to each other. After the front mold and the rear mold are spliced, a wavy gap is formed and the front mold and the rear mold clamp the skirt. The bottom of the front mold and the rear mold are not conductive. The workbench is also provided with a fixing member for clamping the belt.

[0005] Although the scheme utilizes the front mold, the rear mold, the driving part and the fixing part, so that the work of placing the skirt on the clamp is completed mechanically, the manual work of first inserting the skirt into the clamp and then flipping the clamp onto the belt is reduced, thereby improving the efficiency of welding the skirt to the belt and reducing manpower consumption; at the same time, the driving part drives the front mold and the rear mold to approach the top of the belt, thereby reducing the movement of the belt due to the dragging of the bottom of the front mold and the rear mold, thereby reducing the need to readjust the belt position due to belt sliding, and at the same time, the driving part is used to drive the front mold and the rear mold to move, thereby further reducing manpower consumption and further improving the efficiency of welding the skirt to the belt.

[0006] However, once the wave crest width of the required welding skirt (i.e., the maximum width between the two arcs in the S-shaped skirt) changes, it cannot be applied and the corresponding mold must be replaced to complete the welding of different types of skirts, which increases the cost of the equipment.

DETAILED DESCRIPTION

[0062] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] like Figure 1-Figure 14As shown, the high-frequency welding mold for automatically bypassing the belt skirt according to the embodiment of the present application is connected to an external high-frequency belt welding machine, and the high-frequency welding mold for automatically bypassing the belt skirt is placed on the high-frequency belt welding machine, and is used to position the belt and the skirt, and the skirt is welded to the belt through the high-frequency belt welding machine. Specifically, when practical, the high-frequency welding mold for automatically bypassing the belt skirt is crimped onto the belt, and the skirt to be welded passes through the high-frequency welding mold for automatically bypassing the belt skirt and is fixed on the belt, and then is crimped onto the high-frequency welding mold for automatically bypassing the belt skirt through the high-frequency belt welding machine to weld the skirt to the belt.

[0064] Among them, the high-frequency belt welding machine is an existing technology, and its working principle is not described in detail here.

[0065] Specifically, the belt processing skirt automatic bypass high frequency welding mold of the embodiment of the present application includes a mold shell 1, such as Figure 1-Figure 5 As shown, the two mold shells 1 are symmetrically arranged on the left and right, and the distance between them is adjustable.

[0066] Among them, the mold shell 1 includes an upper mold shell 11 and a side mold shell 12, the side mold shell 12 is fixed to one side of the upper mold shell 11; at least two first slide grooves 111 are symmetrically arranged on the inner bottom of the upper mold shell 11; the side mold shell 12 is evenly arranged with multiple first limit grooves 121 along the length direction.

[0067] A connecting cylinder 13 is arranged between the two symmetrically arranged mold shells 1, one end of the connecting cylinder 13 is fixedly connected to one of the upper mold shells 11, and the other end of the connecting cylinder 13 is fixedly connected to the other upper mold shell 11. The side mold shells 12 on the two symmetrically arranged mold shells 1 are far away from each other.

[0068] It should be noted that the bottom end of one of the side mold shells 12 is rotatably connected to a passive roller 122. It can be understood that when the distance between the two mold shells 1 needs to be changed, the mold shell 1 connected to the telescopic end of the connecting cylinder 13 can be driven to move closer or farther away from the other mold shell 1, and because the bottom end of one of the side mold shells 12 is rotatably connected to a passive roller 122, it is easier to facilitate the displacement change of the mold shell 1.

[0069] Furthermore, a passive mechanism 2 is provided on the side where the two mold shells 1 are close to each other, and an active mechanism 3 is provided on the side where the two mold shells 1 are away from each other. The passive mechanism 2 and the active mechanism 3 cooperate with each other.

[0070] Specifically, Figure 4 , Figure 6-Figure 9As shown, the passive mechanism 2 includes a passive mold body 21, a height limiting component 22 and a depth adjusting member 23. A plurality of passive mold bodies 21 are arranged in a row, and a passive rotating shaft for limiting the shape of the skirt is provided on the passive mold body 21; the height limiting component 22 is slidably connected to the passive mold body 21 and slidably sleeved on the passive rotating shaft; one end of the depth adjusting member 23 is fixed to the mold shell 1, and the other end is slidably connected to the height limiting component 22, and is used to drive the height limiting component 22 to undergo lateral displacement.

[0071] The active mechanism 3 includes a plurality of mutually corresponding positioning plates 31, a positioning cylinder 32, a crimping cylinder 33 and an active mold body 34. The plurality of positioning plates 31 are slidably connected to the mold shell 1. The positioning cylinders 32 and the positioning plates 31 correspond one to one and are fixedly connected. The crimping cylinders 33 and the positioning plates 31 correspond one to one and are fixedly connected. The positioning cylinders 32 and the crimping cylinders 33 are arranged in the same direction, and the telescopic ends of the two are connected to the corresponding active mold body 34. The active mold body 34 is provided with an active rotating shaft that limits the shape of the skirt.

[0072] A plurality of active modules 34 and a plurality of passive modules 21 are arranged alternately, and the spacing between the active modules 34 and the passive modules 21 is adjustable; the spacing between the active rotating shaft and the passive rotating shaft is adjustable, and the two have the same size.

[0073] It is understandable that by changing the spacing between the active shaft and the passive shaft, the active mode body 34 and the passive mode body 21 after the spacing is also changed can be adapted to change and fix the S-shaped wave top width of the skirt.

[0074] In addition, the belt processing skirt automatic bypass high-frequency welding mold according to the embodiment of the present application also has the following additional technical features:

[0075] Further, such as Figure 7 and Fig. 9 As shown, the passive mold body 21 includes a plurality of passive fixed mold shells 211 arranged in a row on the bottom side of the upper mold shell 11, and the space between two adjacent passive fixed mold shells 211 is in a concave arc shape to facilitate shaping of the skirt.

[0076] Specifically, the bottom of the side wall of the passive fixed mold shell 211 arranged in a row is slidably connected with a pressure strip 212. It should be noted that the pressure strip 212 is pressed on the belt to fix the belt on the high-frequency belt welding machine, so the pressure strip 212 is immovable in actual operation.

[0077] Among them, a passive sliding frame 213 is slidably embedded in the passive fixed mold shell 211, and a passive rotating shaft is fixedly connected to the passive sliding frame 213. The passive rotating shaft is a passive pressure roller 214. It can be understood that the passive sliding frame 213 sliding in the passive fixed mold shell 211 can change the position of the passive pressure roller 214.

[0078] Furthermore, a vertical slide groove 215 is vertically arranged on the passive fixed mold shell 211 ; a vertical limit groove 216 is vertically arranged on the passive sliding frame 213 .

[0079] like Figure 6-Figure 9 As shown, the height limiting component 22 includes a height limiting strip 221 adapted to multiple passive mold bodies 21, and second limiting grooves 222 are evenly arranged on the height limiting strip 221. A connecting rod 223 is slidably connected in the second limiting groove 222 along its own length direction. The connecting rod 223 successively penetrates the passive fixed mold shell 211 and the passive sliding frame 213 and is fixedly connected to a limited height ring 224. The height limiting ring 224 is slidably sleeved on the passive pressure roller 214.

[0080] It should be noted that the connecting rod 223 is coupled to the vertical slide groove 215 , that is, the connecting rod 223 can be vertically displaced in the vertical slide groove 215 , and can also be displaced along the length direction of the connecting rod 223 .

[0081] Among them, a limiting protrusion 225 is symmetrically fixed on the side wall of the connecting rod 223, and the limiting protrusion 225 is connected to the limiting sliding rod of the vertical limiting groove 216. It can be understood that the setting of the limiting protrusion 225 enables the connecting rod 223 to be displaced in the vertical limiting groove 216 and only along the length (height) direction of the vertical limiting groove 216.

[0082] It can be understood that, through the setting of the vertical limit groove 216 and the limit protrusion 225, the connecting rod 223 and the passive sliding frame 213 can be displaced along the length direction of the vertical limit groove 216, that is, the connecting rod 223 can drive the height limiting ring 224 on the passive pressure roller 214 to change in height; through the setting of the vertical limit groove 216 and the limit protrusion 225 as well as the connecting rod 223 and the vertical slide groove 215, the connecting rod 223 and the passive sliding frame 213 can be displaced along the length direction of the connecting rod 223 on the passive fixed mold shell 211.

[0083] It should be noted that the limiting slots 226 are symmetrically arranged at both ends of the height limiting strip 221 .

[0084] Furthermore, the depth adjustment member 23 includes a first depth adjustment cylinder 231 fixedly connected to the mold shell 1, the telescopic end of the first depth adjustment cylinder 231 is fixedly connected to a transmission plate 232, the transmission plate 232 is slidably inserted in the limiting slot 226, and the top of the transmission plate 232 is fixedly connected to a first slide bar 233, and the first slide bar 233 and the first slide slot 111 are limited and slidably matched.

[0085] It can be understood that the transmission plate 232 is slidably inserted into the limit card slot 226, so that the height limit bar 221 can drive the connecting rod 223 and the height limit ring 224 to change in the height direction. The telescopic change of the telescopic end of the first depth adjustment cylinder 231 can drive the height limit bar 221 through the transmission plate 232, and then drive the connecting rod 223 and the passive sliding frame 213 to displace along the length direction of the connecting rod 223 on the passive fixed mold shell 211, that is, the passive pressure roller 214 extends or retracts from the passive fixed mold shell 211.

[0086] Furthermore, as Figure 6 、 Figure 7 、 Figure 10-12 shown, multiple positioning plates 31 are arranged in a row. One end of the positioning plate 31 is fixedly connected with a limit pillar 311. The limit pillar 311 corresponds to and is slidably connected with the first limit slot 121 one by one. It should be noted that the limit pillar 311 and the first limit slot 121 can displace only along the length direction of the first limit slot 121.

[0087] Among them, the telescopic end of the positioning cylinder 32 is fixedly connected with a positioning baffle 321; the telescopic end of the pressing cylinder 33 is fixedly connected with a pressing frame 331, and the pressing frame 331 is arranged in a U shape.

[0088] Furthermore, as Figure 7 、 Fig.10 and Fig.11 shown, the active mold body 34 includes an active fixed mold shell 341 fixedly connected to the positioning baffle 321. An active sliding frame 342 is slidably connected to the active fixed mold shell 341. An active rotating shaft is fixedly embedded in the active sliding frame 342, and the active rotating shaft is an active pressure roller 343. One side of the active sliding frame 342 is fixedly connected with a sliding frame 344, and the sliding frame 344 is slidably inserted into the active fixed mold shell 341.

[0089] It should be noted that the adjacent two active fixed mold shells 341 are arranged in an inward concave arc shape. It can be understood that the active fixed mold shell 341 and the passive fixed mold shell 211 are arranged alternately. Through the arc-shaped settings of their respective adjacencies, the shape of the skirt is limited.

[0090] Furthermore, the pressing frame 331 is fixedly connected to the side of the active fixed mold shell 341 away from the active sliding frame 342. A second depth adjustment cylinder 345 is fixedly connected inside the pressing frame 331, and the telescopic end of the second depth adjustment cylinder 345 is fixedly connected to one end of the sliding frame 344 away from the active sliding frame 342.

[0091] It can be understood that the telescopic change of the telescopic end of the second depth adjustment cylinder 345 can drive the sliding frame 344 and the active sliding frame 342 fixed to the sliding frame 344 to undergo displacement changes, that is, the active sliding frame 342 and the active pressure roller 343 therein are displaced on the active fixed mold shell 341 along the length direction of the sliding frame 344, and the telescopic change of the telescopic end of the crimping cylinder 33 can drive the entire active fixed mold shell 341 and its upper parts to undergo overall displacement, that is, to move closer to or away from the passive fixed mold shell 211.

[0092] The following describes the use process of the belt processing skirt automatic bypass high frequency welding mold according to the embodiment of the present application with reference to the accompanying drawings:

[0093] When in use, according to the actual width of the belt, the distance between the two mold shells 1 is adjusted by the telescopic change of the telescopic end of the connecting cylinder 13, and then the two mold shells 1 connected as one are crimped onto the belt. It should be noted that at this time, the first depth adjustment cylinder 231, the positioning cylinder 32, the crimping cylinder 33 and the second depth adjustment cylinder 345 are all in a contracted state, that is, the passive pressure roller 214 and the active pressure roller 343 are in a distanced state, and the passive fixed mold shell 211 and the active fixed mold shell 341 are also in a distanced state, and the skirt is removed from the mold shell 1 through the feeding structure (conveying skirt) on the high-frequency belt welding machine. The feeding end of the mold shell 1 is inserted, and after passing through the rows of passive pressure rollers 214 and active pressure rollers 343, it is pulled out from the discharge end of the mold shell 1, and then the positioning cylinder 32 and the crimping cylinder 33 are started to push the active fixed mold shell 341 toward the passive fixed mold shell 211. The specific spacing between the two is determined according to the actual wave crest width of the processed skirt, and the elongation of the telescopic end of the first depth adjustment cylinder 231 drives the height limit strip 221 to move, and the passive pressure roller 214 is extended on the passive fixed mold shell 211 through the connecting rod 223 and the passive sliding frame 213, and the skirt is pushed to abut against the arc between the corresponding two active fixed mold shells 341. Similarly , start the second depth adjustment cylinder 345, and through the elongation change of its telescopic end, the sliding frame 344 drives the active sliding frame 342 and the active pressing roller 343 thereon to extend out from the active fixed mold shell 341, and pushes the skirt to abut against the arc between the two corresponding passive fixed mold shells 211. It should be noted that when the skirt is pushed to the arc between the two corresponding active fixed mold shells 341, the height change of the height limiting strip 221 can drive the connecting rod 223 and the height limiting ring 224 to change in height synchronously, and the height limiting ring 224 is used to press the top of the skirt to avoid local height change of the skirt during the pushing process. Changes, and avoid the occurrence of skirt welding errors caused by local bulging of the belt in the mold. Specifically, because the passive pressure roller 214 and the active pressure roller 343 are arranged in a row, the starting sequence is arranged from the discharge end side to the feeding end side, so that the passive pressure roller 214 and the active pressure roller 343 located at the discharge end and the two corresponding active fixed mold shells 341 and the two passive fixed mold shells 211 can position the skirt, preventing the first depth adjustment cylinder 231 and the second depth adjustment cylinder 345 that are started in sequence later from pulling the skirt from the discharge end to the inside of the mold shell 1, that is, this starting sequence can position the skirt on the belt;After the skirt in the mold shell 1 is crimped, the high-frequency belt welding machine is started to weld the positioned skirt to the belt. After welding, the positioning cylinder 32 is controlled to be retracted. In this process, multiple positioning cylinders 32 can be retracted at the same time, and then the crimping cylinder 33 is retracted from the feeding end to the discharging end in sequence, that is, the active fixed mold shell 341 is moved away from the passive fixed mold shell 211 in sequence, and then the originally fixed skirt is released at this time, and the welded skirt and belt are pulled out to the discharging end, and the above operation is continued, and the subsequent belts are continued to be welded. It should be noted that the design of the present application can make the high-frequency welding mold for the automatic detour of the belt processing skirt suitable for the welding of belts with different wave top widths, and the skirts can be welded on both sides of the belt at the same time, which improves the welding efficiency and the practicality of the high-frequency welding mold, and reduces the production cost of the enterprise. ;

[0094] In the related art, the belt-processed skirt automatically bypasses the high-frequency welding mold. When in actual use, not only will the width of the skirt wave top change, but the wave pitch of the skirt will also vary due to different specifications. If the wave pitch changes, the above-mentioned belt-processed skirt automatically bypasses the high-frequency welding mold and cannot be applied. If the mold is replaced, the production cost of the enterprise will still increase.

[0095] According to some embodiments of the present application, Figure 1-Figure 4 ,as well as Figure 6 and Fig.12 As shown, the bottom side of the mold shell 1 is connected to a lifting mechanism 4, which includes a lifting component 41 arranged on the bottom side of the mold shell 1, and the lifting end of the lifting component 41 is slidably embedded in the mold shell 1, and the lifting end of the lifting component 41 covers the passive mold body 21 and the positioning plate 31.

[0096] Among them, two groups of expansion components 42 are set at the lifting end of the lifting component 41, and the two groups of expansion components 42 are respectively connected to the passive mold body 21 and the positioning plate 31. The expansion components 42 respectively cause the passive mold body 21 and the positioning plate 31 to undergo the same displacement changes under the displacement action of the lifting end of the lifting component 41.

[0097] Specifically, the lifting assembly 41 includes a bracket 411 fixedly connected to the mold shell 1 , a lifting cylinder 412 is fixedly connected to the bracket 411 , and a lifting plate 413 is fixedly connected to the telescopic end of the lifting cylinder 412 .

[0098] It can be understood that the telescopic change of the telescopic end of the lifting cylinder 412 will drive the lifting plate 413 to change in height on the mold shell 1 (upper mold shell 11).

[0099] Furthermore, two second sliding grooves 414 are symmetrically arranged on the bottom side of the lifting plate 413 .

[0100] Furthermore, Figure 6 As shown, each group of expansion components 42 is composed of multiple individual expansion components 42 in a row, and a single expansion component 42 includes a first expansion bar 421, a second expansion bar 422, a top hinge seat 423 and a bottom hinge seat 424. The first expansion bar 421 and the second expansion bar 422 are hinged to the top hinge seat 423, and the top hinge seat 423 is connected to the lifting plate 413.

[0101] The second expansion bar 422 in the first separate expansion component 42 and the first expansion bar 421 in another adjacent separate expansion component 42 are hinged to the bottom hinge seat 424 .

[0102] One group of bottom hinged seats 424 are respectively fixed to the plurality of passive mold bodies 21 , and the other group of bottom hinged seats 424 are respectively fixed to the plurality of active mold bodies 34 .

[0103] Furthermore, the first top hinged seat 423 located at the same end of the two sets of expansion components 42 is respectively fixed to the mold shell 1. Preferably, in the specific embodiment of the present application, the first separate expansion component 42 is located on the feeding end side, and the last separate expansion component 42 is located on the discharge end side.

[0104] The top ends of the other top hinged seats 423 are respectively fixed with second slide bars 425 , and the plurality of second slide bars 425 are respectively connected to the corresponding second slide grooves 414 in a limited sliding manner.

[0105] It can be understood that when the lifting plate 413 descends, the angle between the first expansion bar 421 and the second expansion bar 422 on all expansion components 42 will become larger, that is, the top hinge seat 423 will move closer to the bottom hinge seat 424, while the lengths of the first expansion bar 421 and the second expansion bar 422 remain unchanged. It can be understood that from the first passive fixed mold shell 211 and the first positioning plate 31, the multiple passive fixed mold shells 211 and the multiple positioning plates 31 arranged behind will be displaced at the same distance. In the specific displacement process, the limiting pillar 311 is displaced in the first limiting groove 121, and the connecting rod 223 is displaced in the second limiting groove 222.

[0106] Therefore, during specific use, during the actual operation, when the wave pitch of the skirt changes, according to the specific size of the wave pitch, the lifting cylinder 412 is started, and the telescopic change of its telescopic end is used to drive the lifting plate 413 to change in height on the upper mold shell 11, and then further change the angle between the first expansion bar 421 and the second expansion bar 422 on all the expansion components 42 below the lifting plate 413. It should be noted that when the angle becomes larger, except for the first passive fixed mold shell 211 and the first positioning plate 31, the positions of the multiple passive fixed mold shells 211 and the multiple positioning plates 31 arranged behind will move away from each other by the same distance, that is, at this time, the distance between the two adjacent passive fixed mold shells 211 and the two adjacent active fixed mold shells 341 becomes larger, and similarly, the two adjacent passive pressure rollers 214 and the two adjacent active pressure rollers 343 The spacing between them also becomes larger. It should be noted that the size of the above spacing changes in the same way; on the contrary, when the angle becomes smaller, it can be understood that the spacing between the two adjacent passive fixed mold shells 211, the two adjacent active fixed mold shells 341, the two adjacent passive pressure rollers 214 and the two adjacent active pressure rollers 343 also becomes smaller. In this way, the high-frequency welding mold for automatic bypassing of the belt processing skirt in the embodiment of the present application can be applied to the changes in the wave pitch of different skirts during actual use, and can be applied to the changes in different wave top widths of the skirt according to the above description. In this way, the actual applicability of the high-frequency welding mold for automatic bypassing of the belt processing skirt in the embodiment of the present application is greatly improved, the production cost of the enterprise is reduced, and there is no need to frequently remove or put the high-frequency welding mold on the high-frequency belt welding machine, thereby avoiding damage caused by falling or bumping during transportation.

[0107] In the related art, the belt processing skirt automatically bypasses the high-frequency welding mold. After the skirt is welded, when welding the skirt of the following belt, it is necessary to manually pull out the welded belt and the skirt thereon, and then reuse the belt processing skirt automatically bypass the high-frequency welding mold to position and crimp the following belt. In this process, errors in the belt pulling length are prone to occur, and positioning errors are prone to occur when the belt is repositioned. Once the above errors occur, the skirt welding on the entire belt will be uneven or uneven, and frequent corrections will greatly reduce the welding efficiency of the skirt.

[0108] According to some embodiments of the present application, Figure 1-Figure 3 and 13 and Fig.14 As shown, two traction mechanisms 5 are symmetrically arranged at the discharge ends of the two mold shells 1 , and the two traction mechanisms 5 have the same structure and size.

[0109] Specifically, the traction mechanism 5 includes a supporting assembly 51 fixed to the side of the mold shell 1 , a pressing assembly 52 fixed to the discharge end of the mold shell 1 , and a traction assembly 53 fixed to the movable end of the pressing assembly 52 .

[0110] It should be noted that the two pressing components 52 are respectively located at one side of the discharge ends of the two mold shells 1 and close to each other.

[0111] The supporting assembly 51 includes a supporting cylinder 511 fixedly connected to the side wall of the mold shell 1 , and a supporting plate 512 is fixedly connected to the telescopic end of the supporting cylinder 511 .

[0112] It can be understood that when the belt needs to be moved, the telescopic end of the support cylinder 511 is changed and the support plate 512 is used to abut against the high-frequency belt welding machine, so that the entire mold shell 1, namely the passive mechanism 2, active mechanism 3 and lifting mechanism 4 thereon, is lifted, that is, the belt is no longer fixed by the pressure strip 212.

[0113] Furthermore, the pressing assembly 52 includes a fixing seat 521 fixedly connected to one side of the discharge end of the mold shell 1 , and a pressing cylinder 522 is fixedly connected to the fixing seat 521 .

[0114] Furthermore, the traction assembly 53 includes a lower pressure plate 531 fixedly connected to the telescopic end of the lower pressure cylinder 522, and a bottom plate 532 is slidably inserted on the lower pressure plate 531. It can be understood that the telescopic change of the telescopic end of the lower pressure cylinder 522 can drive the lower pressure plate 531 to change in height relative to the bottom plate 532.

[0115] Among them, a traction motor 533 and an active roller 534 are arranged on the lower pressure plate 531, and the traction motor 533 and the active roller 534 are connected by a transmission belt 535. It can be understood that the rotation of the output end of the traction motor 533 will drive the active roller 534 to follow the rotation.

[0116] Furthermore, a driven roller 536 is provided on the bottom plate 532, and the driven roller 536 is adapted to the active roller 534. It should be noted that, Figure 1-Figure 3 as well as Fig.13 As shown, the driven roller 536 is located directly below the active roller 534 .

[0117] Furthermore, the two lower pressure plates 531 symmetrically arranged at one end of the two mold shells 1 have their ends away from each other higher than their ends close to each other. It should be noted that the frame formed between the lower pressure plate 531 and the bottom plate 532 must be able to allow the belt with a skirt welded therein to pass through. In this way, the height of the frame close to the positioning plate 31 is greater than the height of the frame away from the positioning plate 31, so that the belt with a skirt welded therein can pass smoothly.

[0118] The two symmetrical active rollers 534 are respectively located at the ends of the two lower pressing plates 531 that are close to each other.

[0119] Therefore, when it is used, the belt coming out from the discharge end and the skirt welded thereon pass through the frame formed between the lower pressure plate 531 and the bottom plate 532 and between the corresponding driven roller 536 and the active roller 534 (it should be noted that only the belt passes between the driven roller 536 and the active roller 534, and the skirt is located on the outside of the two rollers), and then the distance between the driven roller 536 and the active roller 534 is corrected by the telescopic change of the telescopic end of the lower pressure cylinder 522, so that the driven roller 536 and the active roller 534 are aligned. The active roller 534 clamps the belt. After the skirt in the high-frequency welding mold is welded, the active fixed mold shell 341 is first moved away from the passive fixed mold shell 211, that is, the skirt is no longer clamped and positioned, and then the top support cylinder 511 is started to make the support plate 512 abut against the high-frequency belt welding machine, and the entire mold shell 1, that is, the passive mechanism 2, the active mechanism 3 and the lifting mechanism 4 thereon are raised, so that the belt in the mold is no longer pressed and fixed by the pressure strip 212, and then the downward pressure cylinder 522 is started. The driven roller 536 and the active roller 534 clamp the belt, and then the traction motor 533 is started. The active roller 534 rotates and cooperates with the driven roller 536 to transport the belt outward, that is, the belt with the welded skirt and the skirt are transported out from the mold range. Specifically, the rotation time and speed of the traction motor 533 can be determined according to the required length of the conveying belt. The detailed parameters and setting rules are already very mature in the prior art and are not described here. After the welded belt and skirt are transported out, the operation is reversed to re-press the pressure strip 212 on the belt to be welded, and the above welding action is continued. The design of the present application, through the symmetrical conveyance of the belt by two sets of driven rollers 536 and active rollers 534, can maintain the stability of the belt during the conveying process and avoid the belt from being skewed. At the same time, it avoids the phenomenon that the subsequent belt to be welded needs to be repositioned due to manual pulling of the welded belt, thereby improving the continuous welding capacity of the belt skirt and further improving the welding efficiency of the skirt.

[0120] It should be noted that the specific models and specifications of the connecting cylinder 13, the first depth adjustment cylinder 231, the positioning cylinder 32, the crimping cylinder 33, the second depth adjustment cylinder 345, the lifting cylinder 412, the downward pressure cylinder 522 and the traction motor 533 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0121] The above are only preferred implementations of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
