Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of cloth roll packaging, and in particular, to a textile cloth roll packaging device. Background Art

[0002] In the textile industry, rolls of fabric (such as cotton, linen, and chemical fiber) are typically packaged using heat shrink film. The core process includes wrapping the roll with film, sealing and shearing the ends, and heat shrinking and shaping. The end-sealing and shearing process is crucial for packaging quality. Excess film must be cut off at both ends of the roll and heat-sealed to prevent cracking during the subsequent heat shrink process.

[0003] After wrapping the film, existing equipment typically uses clamps or rollers to flatten the film scraps at both ends of the roll (e.g., squeezing them toward the center of the end face). Heat-sealing knives are then used to perform long-distance flat heat sealing and cutting. However, despite the scraps being gathered before heat sealing, the shrinking film is essentially folded and stacked. The heat sealing process only achieves linear fusion of the film, resulting in a limited effective sealing interface that cannot withstand the stress generated by the circumferential contraction of the film during heat shrinkage. In practice, these flat heat seals are prone to cracking, delamination, or a weak seal, causing the film to break at both ends of the roll during the heat shrinking phase, compromising the sealing and reliability of the package.

[0004] With the increasing demand for packaging appearance and protective properties for high-end textile fabrics (such as silk and medical fabrics), and the widespread use of diverse film materials such as PE, POF, and biodegradable films, the shortcomings of existing flat heat-sealing processes have become increasingly apparent. The existing end-face plastic sealing and shearing process, due to limitations in waste edge treatment, suffers from core issues such as poor fusion and stress concentration. Technological breakthroughs are urgently needed through structural innovation and process optimization to meet higher packaging standards. Summary of the Invention

[0005] In order to overcome the above-mentioned defects, an embodiment of the present invention provides a textile cloth roll packaging device, which solves the technical problem that the textile cloth roll packaging device in the prior art only folds, heat seals and cuts the waste edges of the film at both ends of the cloth roll after completing the film coating, resulting in limited end face sealing interface and concentrated shrinkage stress, and then the two ends of the film are prone to cracking during the heat shrinkage stage of the cloth roll.

[0006] According to one aspect, at least one embodiment of the present invention provides a textile cloth roll packaging device, comprising a workbench and a wrapping device and an end-sealing device disposed on the workbench, wherein the end-sealing device is used to wrap a film onto a cloth roll; the end-sealing device is provided with two film waste edges, each of which is used to heat-seal the waste edges of the film at both ends of the cloth roll; the end-sealing device comprises:

[0007] A sliding bin is slidably arranged on the workbench and can be moved closer to or further away from the end of the cloth roll. The sliding bin has an air exhaust port connected to the air exhaust device, and the air exhaust port is used to absorb the film waste edge on the end surface of the cloth roll;

[0008] A clamping mechanism, the clamping mechanism being rotatably disposed in the sliding chamber and being used for clamping the film scrap and driving the film scrap to rotate, so as to twist the film scrap into a spiral multi-layer structure;

[0009] The heat sealing and cutting mechanism is arranged in the sliding chamber and is located on the side of the clamping mechanism close to the cloth roll. The heat sealing and cutting mechanism is used to heat seal and cut the twisted waste edge of the film.

[0010] For example, in a textile fabric roll packaging device provided by at least one embodiment of the present invention, the clamping mechanism includes:

[0011] a base plate, the base plate being rotatably connected to the inner wall of the sliding chamber, the base plate being provided with a first air outlet communicating with the air outlet, and the base plate being provided with a first sliding groove extending in a radial direction;

[0012] A closing splint, wherein the number of the closing splints is several, the closing splints are slidably connected to the side of the base plate, one side wall of the closing splint has a first protrusion for slidingly engaging with the first slide groove, the other side wall has a second protrusion, and the closing splint has a closing angle arranged near the axis side of the base plate;

[0013] The cam is adapted to move the locking cam over the locking cam, and the locking cam is adapted to move the locking cam over the locking cam, so that the locking cam can move relative to the first locking cam and the locking cam can move relative to the first locking cam.

[0014] For example, in a textile cloth roll packaging device provided by at least one embodiment of the present invention, the closed corner has a sharp protrusion for contacting the waste edge of the film, and the sharp protrusions of several closed corners are used to pierce the waste edge of the film to limit the relative position of the closed corner and the waste edge of the film.

[0015] For example, in a textile fabric roll packaging device provided by at least one embodiment of the present invention, the clamping mechanism further includes:

[0016] a telescopic member, one end of which is hingedly provided on the base plate and the other end of which is hingedly provided on the rotating plate, and the telescopic member is used to drive the rotating plate to rotate relative to the base plate;

[0017] A rotation driving member is provided on the sliding chamber, and an output end of the rotation driving member is engaged with an outer peripheral edge of the substrate to drive the substrate to rotate in the sliding chamber.

[0018] For example, in a textile cloth roll packaging device provided by at least one embodiment of the present invention, the sealing device also includes two gathering plates, both of which are located at one end of the sliding bin close to the cloth roll and are respectively located on the upper and lower sides of the cloth roll. The gathering plates can slide toward each other to preliminarily gather the waste edges of the film entering the exhaust port.

[0019] For example, in a textile cloth roll packaging device provided by at least one embodiment of the present invention, the two gathering plates are staggered along the axis of the cloth roll, and the adjacent sides of the two gathering plates have clamping grooves for abutting against the waste edges of the film.

[0020] For example, in a textile fabric roll packaging device provided by at least one embodiment of the present invention, the heat sealing and cutting mechanism includes:

[0021] Sliding racks, wherein there are two sliding racks, and the two sliding racks are vertically slidably arranged in the sliding bin and located on both sides of the air exhaust port;

[0022] There are two mounting plates, and the two mounting plates are respectively slidably arranged on the two sliding frames, and the two mounting plates can slide toward each other;

[0023] There are two heating plates, each of which is slidably connected to adjacent sides of the two mounting plates. The heating plate has a heating surface on the side facing the air outlet, and the heating surface is used to heat-melt the waste edge of the film;

[0024] There are two cutting knives, and the two cutting knives are respectively arranged on the two mounting plates. The cutting edges of the two cutting knives are both facing the axial side of the exhaust port, and are used to cut the waste edges of the film; after the two mounting plates slide close together, the heating surface contacts the twisted waste edges of the film before the cutting edges of the cutting knives.

[0025] For example, in a textile cloth roll packaging device provided by at least one embodiment of the present invention, the heating plate has a guide column on the side away from the heating surface, the guide column passes through and is slidably connected to the mounting plate, and a first elastic member is sleeved on the guide column, and the two ends of the first elastic member act on the mounting plate and the heating plate respectively, and are used to elastically push the heating plate so that the heating plate slides away from the mounting plate.

[0026] For example, in a textile cloth roll packaging device provided by at least one embodiment of the present invention, the guide column is provided with a plurality of radially through and axially spaced limiting holes, and a threaded limiting rod is provided in the limiting hole on the side of the mounting plate away from the heating plate, and the limiting rod is used to limit the sliding range of the guide column on the mounting plate.

[0027] For example, in a textile fabric roll packaging device provided by at least one embodiment of the present invention, adjacent sides of the two heating plates are slidably connected to detachable members that can move toward each other, and a second elastic member is provided between the detachable members and the heating plates, and the second elastic member is used to elastically pull the detachable members to move the detachable members away from the heating plates;

[0028] When the two mounting plates are close to each other, the two separation members can contact the waste edge of the film before the heating plate; when the two mounting plates are moved away from each other, the two separation members can finally separate from the waste edge of the film, so that the waste edge of the film after heat melting is separated from the heating plate;

[0029] The separation member divides the heating surface into a first hot-melt section and a second hot-melt section, the first hot-melt section is close to the cloth roll, the second hot-melt section is close to the air outlet, and the width of the first hot-melt section along the cloth roll axis is smaller than the width of the second hot-melt section along the cloth roll axis;

[0030] After the separation member and the heating plate are in contact with the waste edge of the film, the first hot melt section is used to melt the waste edge of the film to form a safety melting section, and the second hot melt section is used to melt the waste edge of the film to form a sealing melting section.

[0031] The beneficial effects of the embodiments of the present invention are:

[0032] In the present invention, the sliding bin of the sealing device can be close to or away from the end of the cloth roll, and the waste edge of the film can be adsorbed through the exhaust port. Compared with the existing equipment that only gathers the waste edge of the film through the clamp or pressure roller plane, it can not only initially gather the waste edge of the film, but also make the film more flatly fixed on the cloth roll, providing a good foundation for subsequent processing. The clamping mechanism twists the waste edge of the film into a spiral multi-layer structure, which changes the state of folding and stacking of the waste edge of the film in the existing technology and significantly increases the contact area between the films. When the heat sealing and cutting mechanism is working, the heating surface contacts the waste edge of the film before the cutting blade, ensuring that the heat sealing process is carried out before cutting. The spiral multi-layer structure can achieve fusion of multiple layers of film during heat sealing, effectively increasing the sealing interface, and dispersing the stress generated by the circumferential contraction of the film during heat shrinkage, avoiding the problems of cracks, delamination or false sealing at the seal due to the limited sealing interface and stress concentration of the existing flat heat sealing, greatly improving the sealing and reliability of the cloth roll packaging, and meeting the higher requirements of high-end textile fabrics for packaging.

Therefore, it should not be understood as a limitation on the present invention.

[0051] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0052] like Figures 1 to 5 FIG. 1 shows a textile fabric roll packaging device according to an embodiment of the present invention. The device comprises a workbench 4, on which are mounted a wrapping device 2 and two end-sealing devices 6, one for each end of a fabric roll 1. The wrapping device 2 is used to wrap a film around the fabric roll 1. After wrapping, the end-sealing devices 6 heat-seal the waste film edges at both ends of the fabric roll 1.

[0053] The end-sealing device 6 consists of a sliding chamber 7, a clamping mechanism 8, and a heat-sealing and cutting mechanism 9. The sliding chamber 7 is slidably connected to the workbench 4 via guide rails, allowing it to be moved closer to or further away from the end of the fabric roll 1 along its axis. An exhaust passage is provided within the sliding chamber 7, with an exhaust port 71 located near the end of the fabric roll 1. This exhaust port 71 is connected to the exhaust device via a pipe. When the exhaust device is in operation, the exhaust port 71 generates an adsorption force, drawing the film waste edge from the end of the fabric roll 1 toward the exhaust port 71, thereby ensuring that the waste edge of the film is evenly attached to the fabric roll 1.

[0054] The clamping mechanism 8 is rotatably mounted in the sliding chamber 7. During clamping, the clamping mechanism 8 is actuated by mechanical transmission or other driving means to clamp the film scrap edge and drive the clamped film scrap edge to rotate, thereby twisting the film scrap edge into a spiral multi-layer structure.

[0055] Heat-sealing and cutting mechanism 9 is disposed within sliding chamber 7 and located on the side of clamping mechanism 8 closest to fabric roll 1. Heat-sealing and cutting mechanism 9 utilizes a mechanical transmission structure. After the film scrap edge is twisted, two mounting plates 92 slide toward each other, allowing heating surface 931 to first contact the twisted film scrap edge, heat-sealing the scrap edge. Subsequently, the cutting edge of cutting blade 94 contacts the film scrap edge, shearing off the excess film scrap edge, thus completing the heat-sealing and cutting process of the film scrap edge at the end of fabric roll 1.

[0056] The sliding chamber 7 of the sealing device 6 can be moved closer to or further away from the end of the cloth roll 1, and the film waste edges are sucked in through the exhaust port 71. Compared with existing equipment that only gathers the film waste edges through a clamp or pressure roller plane, this device can not only initially gather the film waste edges, but also fix the film more evenly on the cloth roll 1, providing a good foundation for subsequent processing. The clamping mechanism 8 twists the film waste edges into a spiral multi-layer structure, changing the state of folded and stacked film waste edges in the existing technology and significantly increasing the contact area between the films. When the heat sealing and cutting mechanism 9 is in operation, the heating surface 931 contacts the film waste edges before the cutting blade 94, ensuring that the heat sealing process is carried out before cutting. The spiral multi-layer structure can achieve fusion of multiple layers of film during heat sealing, effectively increasing the sealing interface and dissipating the stress generated by the circumferential contraction of the film during heat shrinkage. This avoids the problems of cracks, delamination, or false seals at the seal caused by the limited sealing interface and stress concentration of existing flat heat seals. This greatly improves the sealing and reliability of the cloth roll 1 packaging, meeting the higher packaging requirements of high-end textile fabrics.

[0057] like Figures 6 to 11As shown, the clamping mechanism 8 includes a base plate 81, a closing clamp plate 82, a rotating plate 83, a telescopic member 84, and a rotating driving member 85. The base plate 81 is rotatably connected to the inner wall of the sliding chamber 7 via a bearing. A first air outlet 811 communicating with the air exhaust port 71 is provided through the middle portion thereof. A plurality of first sliding grooves 812 are radially provided on its side surface. The number of closing clamp plates 82 corresponds to the number of first sliding grooves 812. The first protrusions 823 on the side wall are inserted into the first sliding grooves 812 for sliding. A second protrusion 824 is provided on the other side wall. A closing angle 825 is formed at one end of the closing clamp plate 82 near the axis of the base plate 81. A spike protrusion 826 is provided on the edge of the closing angle 825. The spike protrusion 826 is prismatic, with the tip facing the axis of the base plate 81 and capable of piercing the surface layer of the waste edge of the film to form a limiting anchor point. The rotating plate 83 is slidably connected to the outside of the closed clamping plate 82 through a guide structure and can rotate relative to the base plate 81. A second air outlet 831 connected to the first air outlet 811 is provided in the middle, and a second slide groove 832 uniformly distributed circumferentially is provided on the surface. The extension direction of the second slide groove 832 forms an angle with the radial direction of the rotating plate 83. One end of the telescopic member 84 is hinged to the base plate 81 and the other end is hinged to the rotating plate 83. The rotating plate 83 is driven to rotate around the center of the base plate 81 through the telescopic action, so that the inner wall of the second slide groove 832 pushes the second protrusion 824 of the closed clamping plate 82, driving the closed clamping plate 82 to slide along the first slide groove 812 and swing around the first protrusion 823. The closing angle 825 is retracted toward the axis side of the rotating plate 83 to clamp the waste edge of the film; the rotating driving member 85 is arranged on the sliding bin 7, and its output end is engaged with the gear ring on the outer peripheral edge of the base plate 81. The base plate 81 is driven to rotate in the sliding bin 7 through gear transmission, thereby driving the clamped waste edge of the film to make a circular motion, twisting the waste edge of the film into a spiral multi-layer structure.

[0058] The base plate 81 and the rotating plate 83 utilize a groove-protrusion coupling structure to convert the circumferential rotation of the rotating plate 83 into a radial retraction motion of the closing clamp 82. This, combined with the precise control of the rotation angle of the rotating plate 83 by the telescopic member 84, enables adaptive adjustment of the clamping force for film scraps of varying thicknesses, ensuring synchronous and uniform clamping of multiple closing clamps 82, and preventing the film scraps from slipping or tearing during the twisting process. The spiked protrusions 826 on the edge of the closing angle 825 physically pierce and limit the film, effectively resolving the problem of slippage when clamping smooth film materials such as PE and POF. This allows the film scraps to maintain a stable positioning during the clamping process, providing a reliable clamping foundation for spiral twisting. The gear transmission structure of the rotating drive member 85 provides stable torque output, ensuring that the base plate 81 rotates at a constant speed, causing the film scraps to twist to form a regular spiral angle, ensuring that the film scraps are uniformly stacked in multiple layers before heat sealing. In addition, when the closing angles 825 are driven by the rotating plate 83 to approach each other, the closing action of the closing angles 825 simultaneously reduces the ventilation area of the exhaust port 71, and preliminarily reduces the air volume between the waste edge of the film and the end face of the cloth roll 1 through mechanical compression. Combined with the negative pressure adsorption of the exhaust device, the residual air between the film and the cloth roll 1 can be quickly and thoroughly discharged, avoiding local bulging or uneven shrinkage caused by residual air during the heat shrinkage process, and providing a flat and tight covering foundation for subsequent heat shrinkage shaping.

[0059] like Figures 2 to 5 As shown, the sliding chamber 7 of the end-sealing device 6 is provided with two gathering plates 10 near one end of the cloth roll 1. The two gathering plates 10 are located on the upper and lower sides of the cloth roll 1 and are connected to the sliding chamber 7 via telescopic cylinders or linear guides. They are staggered along the axis of the cloth roll 1. The end of the upper gathering plate 10 near the cloth roll 1 is offset inward from the sliding chamber 7 relative to the corresponding end of the lower gathering plate 10, forming a staggered three-dimensional gathering structure. V-shaped clamping grooves 1001 are provided on the adjacent sides of the two gathering plates 10. The inner walls of the clamping grooves 1001 are provided with anti-slip patterns or raised structures for contact with the edges of the waste film. A guide slope is also provided on the inner side of the gathering plates 10, which is inclined toward the exhaust port 71. When the sliding bin 7 approaches the end of the cloth roll 1 along the axis of the cloth roll 1 (the sliding bin 7 moves and the exhaust device is continuously turned on), the driving device (such as a cylinder or a screw assembly) drives the two gathering plates 10 to slide toward each other along the linear guide rail. The guiding inclined surface first contacts the waste edge of the film that expands outward from the end face of the cloth roll 1, and squeezes the waste edge toward the center of the air exhaust port 71 through the thrust of the inclined surface. At the same time, the anti-slip structure of the clamping groove 1001 fits tightly with the edge of the waste edge. Through the dual effects of mechanical clamping and inclined surface guidance, the waste edge of the film is initially shaped into a regular shape with the edge converging toward the center, which is convenient for subsequent adsorption by the air exhaust port 71 and processing by the clamping mechanism 8.

[0060] The staggered arrangement of gathering plates 10 overcomes the limitations of traditional planar extrusion. Through a combination of axial dislocation and radial extrusion, three-dimensional gathering of film scraps is achieved. While radially gathering the scraps toward the center of the fabric roll 1, a gradient contraction is formed along the axial direction. The gathering action of the gathering plates 10 determines the length of the film scraps to be twisted, preventing the entire film wrapped around the fabric roll 1 from rotating as the clamping device 8 rotates. The anti-slip structure on the inner wall of the clamping groove 1001 enhances the positioning stability of the film scraps during the gathering process, preventing scrap shifting or sliding due to insufficient friction, ensuring that the scraps form a predetermined regular shape and providing ideal initial conditions for subsequent spiral twisting by the clamping mechanism 8. The synergistic effect of mechanical gathering and vacuum adsorption significantly reduces the adsorption area required for the exhaust port 71, reducing the load on the exhaust device. This is particularly suitable for situations where the scraps are fluffy or irregular after film wrapping, significantly improving the efficiency and accuracy of scrap pretreatment. This structural design optimizes the overall process continuity of the end-sealing device 6, so that the film scrap edge has a stable geometric shape before entering the clamping and twisting process, reducing subsequent sealing defects caused by irregular scrap edge shape from the source.

[0061] like Figures 2 to 5 As shown, the heat-sealing and cutting mechanism 9 comprises two symmetrically arranged sliding frames 91, a mounting plate 92, a heating plate 93, and a cutting blade 94. The sliding frames 91 slide vertically within the sliding chamber 7 and are located on both sides of the air outlet 71. The mounting plate 92 is connected to the sliding frames 91 via transverse slide rails and can slide radially toward or away from the cloth roll 1. The heating plate 93 is slidably connected to the inner side of the mounting plate 92 via a guide post 932. The guide post 932 passes through the mounting plate 92 and is fitted with a first elastic member 95. The ends of the first elastic member 95 act on the mounting plate 92 and the heating plate 93, respectively, to elastically push the heating plate 93 toward the air outlet 71. The guide post 932 is provided with a plurality of radially extending and axially spaced limiting holes 9321, forming multiple gears for controlling the heating time of the heating plate 93. A limiting rod 933 is threadedly connected to the limiting hole 9321 on the side of the mounting plate 92 away from the heating plate 93 to limit the sliding range of the guide post 932. The side of the heating plate 93 facing the air outlet 71 is a heating surface 931. A detachment member 96 is slidably connected to the adjacent side. A second elastic member 97 is disposed between the detachment member 96 and the heating plate 93, elastically pulling the detachment member 96 away from the heating plate 93. The detachment member 96 divides the heating surface 931 into a first hot melt section 9311 near the fabric roll 1 and a second hot melt section 9312 near the air outlet 71. The first hot melt section 9311, extending along the axis of the fabric roll 1, is narrower than the second hot melt section 9312. The cutting blade 94 is fixed to the mounting plate 92, with its cutting edge facing the axis of the air outlet 71 and maintaining a predetermined distance from the heating surface 931.

[0062] When the mounting plates 92 are driven to slide toward each other, the release member 96 contacts the film scrap before the heating plates 93, pre-positioning the twisted film scrap. As the mounting plates 92 continue to slide, the second elastic member 97 is stretched, allowing the two heating plates 93 to continue to move closer together, and the first hot melt section 9311 and second hot melt section 9312 of the heating surface 931 contact the film scrap. When the heating plates 93 reach the travel limit of the limit rod 933, the cutting edge of the cutting blade 94 contacts the scrap and completes the severing. When the mounting plates 92 slide away from each other, the first elastic member 95 releases its elastic potential energy, allowing the heating plates 93 to return to their original position. The release member 96, pulled by the second elastic member 97, maintains contact with the hot melt scrap until it finally separates, preventing the heating plates 93 from adhering to the film.

[0063] The elastic linkage between the heating plate 93 and the release member 96 prevents adhesion between the hot-melt film and the heated surface 931 by enabling the release member 96 to first contact and then separate, ensuring a smooth, tear-free edge after cutting. The limit rod 933 precisely controls the maximum travel of the heating plate 93, preventing the film from melting due to prolonged heat-seal time. The multi-position limit hole 9321 allows for rapid adjustment of heat-sealing pressure, adapting to different film materials and enhancing the versatility of the device.

[0064] The dual heat-melting sections defined by the release element 96 form a gradient sealing structure. The narrow first heat-melting section 9311 acts as a safety melt section, preferentially undergoing controlled collapse when thermal contraction stress is overloaded, providing a pre-set path for stress release. The wide second heat-melting section 9312 acts as a sealing melt section, maintaining the core sealing interface with a larger fusion area. This layered failure mechanism allows for localized deformation while ensuring overall sealing. The heating plate 93 contacts the waste edge before the cutting blade 94, ensuring a continuous "melting first, then cutting" process. This avoids the burrs and incomplete seals that occur in traditional processes when the film is cut before it is fully melted.

[0065] The above structure effectively solves the core problems of insufficient sealing interface, stress concentration and adhesion and tearing in the existing heat sealing and cutting mechanism 9 through the coordinated design of mechanical limitation, elastic compensation and gradient fusion. It is particularly suitable for diversified materials such as PE, POF and degradable films, and improves the yield of the heat shrinkage process and the packaging protection performance.

[0066] The complete workflow is as follows: the wrapping device 2 wraps the film material around the outer surface of the cloth roll 1 to form a complete cylindrical wrapping structure. The film that extends beyond the end surface at both ends of the cloth roll 1 forms waste edges to be processed. At this time, there may be air gaps between the film and the cloth roll 1 that need to be eliminated later.

[0067] The sliding bin 7 is located near the end of the cloth roll 1 along the axis of the cloth roll 1, and the exhaust port 71 is connected to the exhaust device to generate negative pressure adsorption force. Two gathering plates 10 are arranged staggered along the axis at one end of the sliding bin 7 near the cloth roll 1. Under the action of the drive device, they slide toward each other along the linear guide rail. When the sliding bin 7 slides, the exhaust device continuously extracts air. The continuous suction can help to gather the waste edge of the film. The clamping groove 1001 on the inner side of the gathering plate 10 contacts the waste edge of the film that expands outward from the end face of the cloth roll 1. The clamping groove 1001 squeezes the waste edge toward the center of the exhaust port 71 to complete the initial radial gathering, so that the edge of the waste edge naturally converges toward the center of the exhaust port 71 into a regular shape.

[0068] The pre-gathered film waste edges are sucked and adhered to the air outlet 71. The telescopic member 84 drives the rotating plate 83 to rotate around the center of the base plate 81. The second slide groove 832 of the rotating plate 83 pushes the second protrusion 824 of the closing clamping plate 82, causing the closing clamping plate 82 to slide and swing along the first slide groove 812 of the base plate 81. During the swinging process, the ventilation area of the air outlet is gradually reduced, thereby being able to more quickly and thoroughly extract the excess gas in the film.

[0069] The closed angle 825 with the spiked protrusion 826 is retracted toward the axis side, piercing the surface of the waste edge of the film to form a limit anchor point to evenly clamp the waste edge, and then the rotating driving member 85 drives the base plate 81 to rotate through the gear transmission, so that the waste edge of the film between the gathering plate 10 and the clamping mechanism 8 moves in a circular motion with the base plate 81 and is twisted into a spiral multi-layer structure. Through uniform circumferential force, the waste edge is transformed from a flat folding to a three-dimensional spiral stacking to increase the contact area between the film layers.

[0070] The two mounting plates 92 of the heat-sealing and cutting mechanism 9 slide toward each other on the sliding frame 91, executing a "heat-seal first, cut later" sequence. The release member 96 contacts the spiral waste edge before the heating plate 93. As the mounting plate 92 continues to slide, the heating plate 93 approaches, and the first and second heat-melting sections 9311, 9312 of the heating surface 931 contact the film waste edge. When the heating plate 93 reaches the travel limit of the limit rod 933, the cutting edge of the cutting blade 94 contacts the melted waste edge, completing the severance before the heat-sealed layer cools, naturally sealing the edge due to the heat-melting action. As the mounting plate 92 slides in reverse, the release member 96, pulled by the second elastic member 97, finally separates from the waste edge, preventing the heating plate 93 from adhering to the film and ensuring a smooth, tear-free edge after severing. After the waste edge processing is completed at both ends, the sliding chamber 7 returns to its initial position, and the equipment enters the packaging process for the next fabric roll 1.

[0071] Through multi-mechanism collaboration and process sequence design, efficient processing and reliable sealing of film scrap edges are achieved: as the sliding chamber 7 slides, the exhaust device continuously extracts air, and in conjunction with the gathering plate 10, radially compresses and axially positions the scrap edges through the clamping groove 1001, arranging the irregular scrap edges into a regular shape with convergent edges, providing a stable foundation for subsequent clamping and twisting. The clamping mechanism 8 transforms the scrap edges from a flat fold into a spiral multi-layer stack by swinging and closing the clamping plate 82 and rotating the base plate 81. In the process of reducing the diameter of the exhaust port 71, residual air between the film and the cloth roll 1 is expelled, increasing the contact area between the scrap edge layers, changing the simple stacking state of the film in the existing technology, and forming a three-dimensional fusion interface during heat sealing to disperse the circumferential stress of thermal shrinkage.

[0072] The heat sealing and cutting mechanism 9 adopts the timing control of "the separation part 96 contacts first - the heating plate 93 melts in layers - the cutting knife 94 cuts off later". The width difference between the first hot melt section 9311 and the second hot melt section 9312 is designed to form a stress release gradient. When the thermal shrinkage stress is overloaded, the first hot melt section 9311 will preferentially undergo controllable cracking, providing a preset stress release path to avoid the stress from being transferred to the second hot melt section 9312, thereby ensuring the stability of the core sealing interface.

[0073] The heating plate 93 achieves adaptive contact pressure and precise stroke control through guide posts 932, a first elastic member 95, a second elastic member 97, and a limit rod 933. Heat sealing parameters can be adjusted by changing the position of the limit rod 933 according to the characteristics of different film materials, solving problems such as melt-through and false seals caused by material differences. Symmetrical end-sealing devices 6 at both ends of the fabric roll 1 execute each process simultaneously. Through the symmetry of the mechanical structure and synchronous control of the drive system, they ensure consistent scrap edge processing force, torsion angle, and heat sealing temperature at both ends, avoiding packaging leakage caused by unilateral sealing failure. This is suitable for high-end fabrics with stringent packaging requirements. Through mechanical structure innovation and process optimization, the overall process improves packaging sealing and reliability, enhances the equipment's adaptability to diverse film materials, eliminates cracking at both ends of the film during the heat shrink phase, and provides an efficient and stable packaging solution.
