Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and in particular to an end face sealing device and method. Background Art

[0002] In the existing roll packaging process, there are several methods for wrapping the end faces of the roll: 1. Using a fixed-size paper cover or foam cover as the end cover of the roll packaging, the end cover is fixed to the end face of the roll with a packaging film to complete the packaging; 2. Leaving an appropriate amount of packaging film at both ends of the roll, using a plastic cover of the same size as the roll axis to press the excess packaging film to the axis and fix it, thereby completing the packaging of the roll end face; 3. Manually using tape to seal the excess packaging film at both ends of the roll.

[0003] The first two methods of end-face packaging are suitable for packaging processes where coil sizes are relatively close and fixed. Compared to manual methods, they are less adaptable to flexible production. Furthermore, the first two methods require the preparation of end cap materials in advance, which are relatively expensive consumables.

[0004] Since coils are usually long and heavy, manual labor is very labor-intensive. The end-face packaging process requires the cooperation of more than two people.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0053] like Figure 1 As shown, an embodiment of the present application provides an end-face sealing device, which includes a traction and slitting device 600 and a packaging and applicator 100. The traction and slitting device 600 is used to transport the tape to a predetermined position and cut it, while the packaging and applicator 100 is used to, on the one hand, absorb the tape and transport the cut tape to the end of the roll. On the other hand, the packaging and applicator 100 is used to seal the end of the roll in a manner that simulates manual tape sealing. The end-face sealing device of the present application does not require additional consumables such as end caps during the sealing process and has a high degree of automation.

[0054] In some examples, the traction and slitting device 600 includes a roller assembly 601, a traction assembly 602, and a cutting assembly 603. The roller assembly 601 is used to store the tape and guide the end of the tape to the traction assembly 602. The traction assembly 602 pulls the end of the tape, causing it to extend out of the roller assembly 601. After the packaging and applicator 100 absorbs the tape, the cutting assembly 603 cuts the tape, allowing the packaging and applicator 100 to remove the tape from the traction and slitting device 600 and deliver it to the end of the roll.

[0055] Furthermore, the traction and slitting device 600 further includes a support plate 604 , which has a flat surface, and the roller assembly 601 , the traction assembly 602 and the cutting assembly 603 are all arranged on the surface of the support plate 604 .

[0056] like Figure 2 As shown, in some examples, the roller assembly 601 includes a winding roller 701, a supporting roller 702 and a guide roller 703, and the winding roller 701, the supporting roller 702 and the guide roller 703 can all be freely rotatably installed on the support plate 604, and the winding roller 701, the supporting roller 702 and the guide roller 703 all protrude from the plate surface of the support plate 604.

[0057] The winding roller 701 is used to store the rolled tape. When the winding roller 701 rotates in the forward direction, the tape is gradually unwound. Similarly, when the winding roller 701 rotates in the reverse direction, the tape is gradually reeled in.

[0058] Furthermore, the end of the tape is arranged on a guide roller 703, which is located at the connection position between the roller assembly 601 and the traction assembly 602. The guide roller 703 can guide the end of the tape to the traction assembly 602, so that the traction assembly 602 can drive the end of the tape to extend out of the roller assembly 601.

[0059] Specifically, guide rollers 703 include several rollers arranged in pairs, each of which is able to rotate freely. The paired rollers are arranged side by side, with a small spacing between them, facilitating the passage of the tape through the space between them. Consequently, the paired rollers clamp the tape. When the tape is wound and unwound, the tape moves between the rollers. Because the tape is in close contact with the rollers, the moving tape drives the rollers to rotate, creating a low-friction rolling contact between the two rollers, ensuring smooth winding and unwinding of the tape.

[0060] In addition, the support roller 702 is used to support the tape between the winding roller 701 and the guide roller 703. It is understood that the tape is a flexible component. When the tape passes around the support roller 702, the support roller 702 can limit the extension path of the tape, so that the extension path of the tape avoids other components on the support plate 604, ensuring smooth tape winding and unwinding.

[0061] Specifically, the number and arrangement positions of the support rollers 702 can be set according to actual needs. In some embodiments of the present application, two support rollers 702 are provided.

[0062] like Figure 4 As shown, in some examples, the tape needs to be kept taut at all times to ensure that it extends along a predetermined path. To maintain constant tape tension, the winding roller 701 is provided with a first elastic member 704. One end of the first elastic member 704 is fixed to the support plate 604, and the other end of the first elastic member 704 is fixed to the winding roller 701.

[0063] When the adhesive tape has a tendency to loosen, the first elastic component 704 applies elastic force to the winding roller 701, so that the adhesive tape is always in a tensioned state.

[0064] like Figure 3 As shown, the winding roller 701 is provided with a synchronous detection assembly 705, which is used to detect the rotational stroke of the winding roller 701. It is understood that the rotational stroke of the winding roller 701 is positively correlated with the length of the tape extended. The synchronous detection assembly 705 obtains the length of the tape extended by detecting the rotational stroke of the winding roller 701, and uses this to calculate the remaining amount of tape and determine whether the tape has fallen off during the pulling process.

[0065] Specifically, the synchronous detection assembly 705 is disposed on the rotating shaft 401 of the winding roller 701, and the rotating shaft 401 of the winding roller 701 passes through the support plate 604, so that the winding roller 701 and the synchronous detection assembly 705 are respectively located on opposite sides of the support plate 604. It is understood that the winding roller 701, the support roller 702, and the guide roller 703 are located on the same side of the support plate 604.

[0066] In some examples, the traction assembly 602 includes an anti-backward clamping mechanism and a traction clamping mechanism. The anti-backward clamping mechanism is disposed adjacent to the guide roller 703 , and the end of the tape is clamped by the anti-backward clamping mechanism after extending out of the guide roller 703 .

[0067] Furthermore, the traction clamping mechanism is capable of moving, reaching the position of the anti-retraction clamping mechanism, thereby clamping the end of the tape. At this point, the anti-retraction clamping mechanism releases the tape, allowing the traction clamping mechanism to pull the tape. When the traction clamping mechanism moves to its limit position away from the anti-retraction clamping mechanism, the end of the tape reaches a predetermined position, facilitating the tape absorption by the packaging and applying device 100.

[0068] In some examples, the anti-retraction clamping mechanism includes a second clamping component 803 , the overall position of the second clamping component 803 is fixed, and the position of the second clamping component 803 is close to the position of the guide roller 703 , so that the guide roller 703 can guide the end of the tape to the second clamping component 803 .

[0069] Specifically, the second clamping component 803 may adopt a structure capable of opening and closing, and the second clamping component 803 clamps or releases the tape during the opening and closing movement.

[0070] The second clamping component 803 is provided with a second clamping driving component. The second clamping driving component may be a cylinder, and the cylinder is used to drive the second clamping component 803 to perform opening and closing movements.

[0071] In some examples, the traction clamping mechanism includes a first clamping component 801 and a guide drive component 802. The first clamping component 801 is arranged on the guide drive component 802. The guide drive component 802 is used to drive the first clamping component 801 to move, so that the first clamping component 801 is close to the second clamping component 803, or away from the second clamping component 803.

[0072] It can be understood that the first clamping member 801 is used to clamp the end of the tape. After the first clamping member 801 clamps the end of the tape, the movement of the first clamping member 801 can drive the tape to extend.

[0073] Specifically, the first clamping component 801 may also adopt a structure capable of opening and closing, and during the opening and closing movement, the first clamping component 801 can clamp the end of the tape.

[0074] The first clamping component 801 is provided with a first clamping driving component. The first clamping driving component may be a cylinder, and the cylinder is used to drive the first clamping component 801 to perform opening and closing movements.

[0075] In addition, the guide driving component 802 can be a linear cylinder, which can not only drive the first clamping component 801 to move but also limit the moving path of the first clamping component 801 to ensure that the tape extends along a preset direction.

[0076] In some examples, the cutting assembly 603 includes a cutting knife and a cutting drive component disposed on the cutting knife. The cutting drive component can drive the cutting knife to move, thereby realizing the cutting process of the tape.

[0077] Specifically, the cutting drive component can adopt a cylinder.

[0078] The packaging and pasting device 100 of the present application can imitate manual operation processes and adapt to the diameter of the roll material to seal the end face of the roll material, thereby reducing the cost of consumables while improving packaging efficiency, achieving cost reduction and efficiency improvement, and improving the production efficiency of the enterprise.

[0079] like Figure 5 and Figure 6 As shown, an embodiment of the present application provides a packaging applying device 100, which includes a support body 101, a main applying mechanism and a side applying mechanism.

[0080] The support body 101 is a plate-like structure used to house the main and side applicators. The center of the tape is placed in the main applicator. Due to the tape's length, when the center of the tape is placed in the main applicator, the ends of the tape extend beyond the main applicator and lie outside of it. Therefore, the side applicators are located outside the main applicator and serve to house the ends of the tape.

[0081] Furthermore, the main application mechanism is axially movable on the support body 101. Figure 5 The Y-axis direction in the figure is the axial direction of the device, and the side application mechanism is radially movable on the support body 101. Figure 5 The X-axis and Z-axis directions in the figure are both radial directions of the device. During the sealing process of the roll material, the support body 101 gradually moves closer to the roll material until the main applying mechanism contacts the end surface of the roll material, so that the middle of the tape is attached to the end surface of the roll material.

[0082] At the same time, since the position of the roll is constant, as the support body 101 continues to move closer to the roll, the roll pushes the main applicator mechanism to move axially relative to the support body 101, thereby reducing the distance between the main applicator mechanism and the support body 101. During this process, the side applicator mechanism gradually reaches the side of the roll, and the side applicator presses the end of the tape to the side of the roll through radial movement, thus completing the roll sealing process.

[0083] When the packaging and applying device 100 of the present application seals the roll material, it can simulate the manual gluing packaging method without the need for additional components such as end caps, saving consumables and avoiding preparation processes such as end cap size selection, thereby improving the sealing efficiency of the roll material.

[0084] In some examples, the primary application mechanism includes a primary application component 201 having a flat end surface. The middle portion of the tape is located at the end surface of the primary application component 201. As the support 101 gradually approaches the web, the end surface of the primary application component 201 gradually approaches and contacts the end surface of the web. When the end surface of the primary application component 201 contacts the end surface of the web, the sealing process for the middle portion of the tape is complete.

[0085] It is understandable that the adhesive tape contacts the end face of the main application component 201 through the non-adhesive face, while the adhesive face of the adhesive tape faces the end face of the roll, ensuring that the adhesive tape can be sealed to the roll.

[0086] Furthermore, before the tape reaches the end of the roll, the middle of the tape needs to adhere to the end of the main applicator 201 to prevent it from falling. Therefore, the end of the main applicator 201 is provided with a plurality of first suction holes 202. External equipment can draw air between the main applicator 201 and the tape through each of these first suction holes 202, thereby firmly adhering the middle of the tape to the end of the main applicator 201.

[0087] Specifically, the tape is smaller than the end surface of the main application component 201. Therefore, the end surface of the main application component 201 includes an area for tape absorption and an area not requiring tape absorption. It will be understood that the area for tape absorption is determined based on the specific shape of the tape. First suction holes 202 can be evenly distributed throughout the area for tape absorption; areas not requiring tape absorption may be omitted.

[0088] like Figure 7 and Figure 8 As shown, in some examples, the main applying mechanism further includes a first guiding structure, and the first guiding structure is used to limit the moving direction of the main applying component 201, thereby guiding the main applying component 201 to move axially.

[0089] At the same time, the first guide structure also has the function of supporting the main application component 201. The main application component 201 is arranged on the support body 101 through the first guide structure.

[0090] In some examples, the first guide structure includes a first guide shaft 203 and a first guide hole. The first guide shaft 203 is formed into a rod-shaped structure, fixedly connected to the main application component 201, and extends axially along the device. Furthermore, the first guide hole is provided in the support body 101, and the first guide shaft 203 is inserted into the first guide hole, so that the first guide shaft 203 and the support body 101 form a sliding connection. It will be understood that when the main application component 201 moves axially relative to the support body 101, the first guide shaft 203 slides within the first guide hole.

[0091] The first end of the first guide shaft 203 is fixedly connected to the main application component 201, and the second end of the first guide shaft 203 is connected to a limit frame 204. The limit frame 204 is used to limit the maximum axial movement of the main application component 201. When the main application component 201 moves to the limit position in a direction away from the support body 101, the limit frame 204 can contact the support body 101 or other components on the support body 101, thereby preventing the first guide shaft 203 from disengaging from the first guide hole.

[0092] Furthermore, in order to ensure that the first guide shaft 203 slides smoothly in the first guide hole, the support body 101 is provided with a linear bearing at the position of the first guide hole, and the linear bearing protrudes from the plate surface of the support body 101.

[0093] In some examples, a second elastic component is provided between the main application component 201 and the support body 101, and the second elastic component is capable of applying an elastic force to the main application component 201. Specifically, the second elastic component is a spring. When the main application component 201 has not yet contacted the end face of the coil, the second elastic component has a relatively large length. After the main application component 201 contacts the end face of the coil, as the support body 101 moves further, the main application component 201 gradually approaches the support body 101, thereby reducing the length of the spring and putting the spring into a compressed state. When the tape is sealed, the main application component 201 gradually separates from the coil. At this time, the spring applies an elastic force to the main application component 201, driving the main application component 201 away from the support body 101 again, thereby achieving the reset of the main application component 201.

[0094] like Figure 7 and Figure 8 As shown, in some examples, the end of the roll needs to be sealed with multiple strips of tape, and the tapes need to be laid out at a certain angle to ensure the sealing effect. Therefore, the side application mechanism includes multiple side application components, and the side application components correspond to the tapes one by one.

[0095] Each side applicator assembly includes at least two side applicators 301. Since the side applicator mechanism is used to seal the ends of the adhesive tape, and the ends of the adhesive tape are located outside the main applicator assembly 201, the side applicators 301 in each set of side applicator assemblies are located on opposite sides of the main applicator assembly 201 to correspond to the two ends of the adhesive tape.

[0096] In some examples, two mutually perpendicular tapes need to be provided on the end surface of the roll material, so the side applying mechanism includes two side applying components, namely a first side applying component and a second side applying component, and the first side applying component and the second side applying component each include two side applying parts 301.

[0097] Furthermore, in order to adapt to the positional relationship of the two tapes, the arrangement direction of the two side application components 301 in the first side application component and the arrangement direction of the two side application components 301 in the second side application component correspond to Figure 5 When the middle portions of the two adhesive tapes are attached to the main application component 201 and the ends of the two adhesive tapes are attached to the first side application component and the second side application component, the two adhesive tapes are arranged in a cross shape.

[0098] like Figure 6 As shown, in some examples, the side applicator 301 includes a suction surface 302 for adsorbing the tape. When the end surface of the main applicator 201 does not yet contact the end surface of the web, the middle of the tape is adsorbed to the end surface of the main applicator 201, and the end of the tape is adsorbed to the suction surface 302. To ensure that the tape is smoothly adsorbed to the device, the end surface of the main applicator 201 and the suction surface 302 remain coplanar.

[0099] It is understandable that after the end surface of the main applicator 201 contacts the end surface of the coil, as the main applicator 201 moves axially relative to the support body 101 , the main applicator 201 and the adsorption surface 302 are not aligned.

[0100] Furthermore, the adsorption surface 302 is provided with a plurality of second suction holes 303 , and an external device can absorb the gas between the adsorption surface 302 and the tape through each second suction hole 303 , thereby firmly adsorbing the end of the tape to the adsorption surface 302 .

[0101] In some examples, the end surface of the main applicator 201 and the plane where the suction surface 302 lies are both radial planes, while the side applicator 301 further includes a pressing surface 304, and the plane where the pressing surface 304 lies is an axial plane. It is understood that the orientation of the suction surface 302 is different from the orientation of the pressing surface 304.

[0102] Specifically, when the main applying component 201 has not yet contacted the end face of the roll material, the pressing surface 304 faces the main applying component 201; when the main applying component 201 moves axially relative to the support body 101, since the end face of the main applying component 201 and the adsorption surface 302 are not on the same plane, the pressing surface 304 is no longer facing the main applying component 201, and the pressing surface 304 at this time gradually faces the side of the roll material.

[0103] Furthermore, because the middle portion of the tape is attached to the main applicator 201 and the end portion of the tape is attached to the suction surface 302, the tape remains flat when the end portion of the main applicator 201 and the suction surface 302 are coplanar. However, when the end portion of the main applicator 201 and the suction surface 302 are not coplanar, the tape bends, meaning that the end portion of the tape and the middle portion of the tape are no longer in the same plane. It is understood that the length of the tape remains constant. As the main applicator 201 moves axially relative to the support 101, the end portion of the main applicator 201 and the suction surface 302 become not coplanar, and the length of the tape end attached to the suction surface 302 gradually decreases until the end portion of the tape completely overlaps the pressing surface 304. At this point, the pressing surface 304 is already facing the side of the web. In this situation, as the pressing surface 304 gradually contacts the side of the web through radial movement, it seals the end portion of the tape to the side of the web.

[0104] In some examples, the laminating surface 304 is provided with an air hole 305 capable of blowing out air. When the end of the tape overlaps the laminating surface 304, the air blown out of the air hole 305 can drive the end of the tape away from the laminating surface 304, thereby facilitating the end of the tape to be sealed to the side of the roll.

[0105] like Figure 7 and Figure 8 As shown, in some examples, the side applying mechanism further includes a second guiding structure, which is used to limit the moving direction of the side applying component 301, thereby guiding the side applying component 301 to move radially.

[0106] It is understandable that each side applying component 301 is equipped with a second guide structure to facilitate limiting the moving direction of each side applying component 301.

[0107] At the same time, the second guide structure also has the function of supporting the side applying component 301 , and the side applying component 301 is arranged on the supporting body 101 through the second guide structure.

[0108] In some examples, the second guide structure includes a second guide shaft 306 and a second guide hole. The second guide shaft 306 is formed into a rod-shaped structure, fixedly connected to the support body 101, and extends radially along the device. Furthermore, the second guide hole is provided in the side application component 301, and the second guide shaft 306 is inserted into the second guide hole, thereby forming a sliding connection between the second guide shaft 306 and the side application component 301. It will be understood that when the side application component 301 moves radially relative to the support body 101, the second guide shaft 306 slides within the second guide hole.

[0109] The first end of the second guide shaft 306 is fixedly connected to the support body 101, and the second end of the second guide shaft 306 is connected to a limiting component. Specifically, the limiting component is generally formed into a plate-shaped structure. The limiting component is used to limit the radial travel limit of the side application component 301. When the side application component 301 moves away from the support body 101 to the limit position, the limiting component can contact the side application component 301, thereby preventing the second guide shaft 306 from disengaging from the second guide hole.

[0110] Furthermore, to ensure that the second guide shaft 306 slides smoothly in the second guide hole, the side applying component 301 is provided with a linear bearing at the position of the second guide hole, and the linear bearing protrudes from the plate surface of the side applying component 301.

[0111] like Figure 7 and Figure 8 As shown, in some examples, the support body 101 is provided with a driving component 102 , the driving component 102 is formed into a circular ring structure, and the driving component 102 is rotatably connected to the support body 101 .

[0112] Specifically, a circular through-hole is provided in the middle of the support body 101, which penetrates the support body 101 and is used to mount the driving component 102. A rotary bearing is provided between the inner edge of the through-hole and the outer edge of the support body 101 to ensure smooth rotation of the driving component 102.

[0113] Furthermore, a transmission component 103 is provided between the driving component 102 and the side applying component 301, and the transmission component 103 is roughly formed into a rod-shaped structure. The first end of the transmission component 103 is hinged to the edge of the driving component 102, and the second end of the transmission component 103 is hinged to the side applying component 301. During the rotation process, the driving component 102 can drive the first end of the transmission component 103 to change its position along the circumferential direction, so that the transmission component 103 applies a pulling force or a pushing force to the side applying component 301. Specifically, each side applying component 301 is equipped with a transmission component 103. Since each transmission component 103 is installed in the same manner, as the driving component 102 rotates, each transmission component 103 moves with the same amplitude, thereby applying the same pulling force or pushing force to each side applying component 301, ensuring that each side applying component 301 moves radially synchronously.

[0114] It is understood that the side applicator 301 can gradually approach the axis position of the device under the action of tension, and can gradually move away from the axis position of the device under the action of thrust. When the pressing surface 304 of the side applicator 301 is toward the side of the coil, the side applicator 301 gradually contacts the side of the coil under the action of tension, thereby achieving the sealing process of the tape end. After the side applicator 301 completes the sealing process of the tape end, the side applicator 301 gradually moves away from the side of the coil under the action of thrust, thereby achieving the resetting of the side applicator 301.

[0115] In addition, the side application mechanism is further provided with a power component 104. Specifically, the power component 104 can be a cylinder. The fixed end of the cylinder is fixedly mounted on the support body 101, and the output end of the cylinder is connected to the side application component 301. The cylinder drives the side application component 301 to move radially through telescopic motion.

[0116] It is worth noting that only one power component 104 can be provided. Since each transmission component 103 limits each side application component 301 to move with the same amplitude, the power component 104 only acts on a single side application component 301 to achieve synchronous radial movement of all side application components 301.

[0117] like Figure 9 As shown, in some examples, when the device is provided with four side application components 301, the device can seal two tapes to the end surfaces of the roll. The two tapes are at an angle, and to ensure that the ends of the two tapes accurately correspond to the preset side application components 301, the packaging application device 100 also includes an angle adjustment mechanism.

[0118] The angle adjustment mechanism can adjust the angle of the support body 101 so that the preset side application component 301 corresponds to the end of the tape, ensuring that the tape and the side application component 301 match.

[0119] like Figure 5 As shown, in some examples, the angle adjustment mechanism includes a rotating shaft 401, and the support body 101 is fixedly connected to a rotating bracket 402. At the same time, the rotating shaft 401 is fixedly connected to the rotating bracket 402, and the rotating shaft 401 can drive the rotating bracket 402 to rotate, thereby driving the support body 101 to rotate.

[0120] Among them, the rotating bracket 402 includes two detachably connected parts, one part of the rotating bracket 402 is fixedly connected to the support body 101, and the other part of the rotating bracket 402 is fixedly connected to the rotating shaft 401, which facilitates the disassembly of the angle adjustment mechanism and other parts of the device, thereby improving the flexibility of the device.

[0121] Furthermore, the angle adjustment mechanism includes a frame 404, and a clamping block 403 is fixedly mounted on the outer side of the rotating shaft 401. The frame 404 includes a component for outputting linear motion, which is connected to the frame 404 and hinged to the clamping block 403. Specifically, the component for outputting linear motion can be a cylinder, which, through its telescopic motion, drives the clamping block 403 to rotate, thereby driving the rotating shaft 401 to rotate.

[0122] In some examples, the rotating shaft 401 is formed as a hollow cylindrical structure, and the hollow portion of the rotating shaft 401 is used to conduct gas, and the gas in the rotating shaft 401 is used to realize the adsorption process of the main applying component 201 and the side applying component 301 on the tape.

[0123] The rotating bracket 402 has a cavity inside, and the hollow portion of the rotating shaft 401 is connected to the cavity of the rotating bracket 402. The rotating bracket 402 also has a port for conducting gas, which is connected to the side applicator 301 via a corresponding conduit. Therefore, the gas between the side applicator 301 and the end of the tape can be discharged through the hollow portion of the rotating shaft 401, facilitating the side applicator 301's adsorption of the end of the tape.

[0124] like Figure 10 As shown, in some examples, the main applicator 201 is provided with a gas channel, and the gas channel is connected to the rotating bracket 402. Therefore, the gas between the main applicator 201 and the middle portion of the adhesive tape can be conducted along the gas channel to the hollow portion of the rotating shaft 401, facilitating the main applicator 201 to be adsorbed on the middle portion of the adhesive tape.

[0125] Specifically, the main application component 201 is provided with a negative pressure air duct 501, and the hollow portion inside the negative pressure air duct 501 defines a gas channel.

[0126] In some examples, the packaging applicator 100 further includes a vacuum detection sensor 502. The vacuum detection sensor 502 is used to detect the negative pressure between the main applicator 201 and the middle of the tape, ensuring that the main applicator 201 firmly adheres to the middle of the tape. Similarly, the vacuum detection sensor 502 is also used to detect the negative pressure between the side applicators 301 and the ends of the tape, ensuring that the side applicators 301 firmly adhere to the ends of the tape.

[0127] In some examples, the end face sealing equipment also includes a movable module, and the packaging applicator 100 is installed on the movable module. The movable module can drive the packaging applicator 100 to move in multiple axes, so that the position of the packaging applicator 100 corresponds to the end position of the roll material, which facilitates the packaging applicator 100 to achieve sealing of the end face of the roll material.

[0128] Furthermore, the movable module can realize three-axis movement of the packaging and applying device 100, and the movable module includes a first movable module 901, a second movable module 902, and a third movable module 903. The first movable module 901, the second movable module 902, and the third movable module 903 correspond to the three moving axes of the packaging and applying device 100, thereby realizing three-axis movement of the packaging and applying device 100.

[0129] Based on the above-mentioned end face sealing equipment, various embodiments of the end face sealing method of the present application are proposed below.

[0130] The end face sealing method can be applied to the above-mentioned end face sealing device, and the end face sealing method includes but is not limited to the following steps:

[0131] The traction mechanism clamps and pulls the end of the tape to drive the tape to extend;

[0132] The packaging applicator 100 moves to a position corresponding to the extension of the adhesive tape;

[0133] The main applying mechanism and the side applying mechanism absorb the tape by suction, and the cutting assembly 603 cuts the tape;

[0134] The packaging and applying device 100 moves so that the main applying mechanism contacts the end face of the roll material, completing the sealing of the middle part of the tape;

[0135] The packaging applicator 100 moves the main applicator mechanism axially to drive the side applicator mechanism toward the side of the web;

[0136] The side applicator moves radially to complete the sealing of the tape end.

[0137] In some examples, after the tape is loaded, the end of the tape is fixed to the anti-retraction clamping mechanism. The pulling clamping mechanism is reset by movement, and the first clamping member 801 clamps the end of the tape. The second clamping member 803 of the anti-retraction clamping mechanism releases the end of the tape. The first clamping member 801 drives the end of the tape away from the second clamping member 803 until the end of the tape reaches a predetermined position.

[0138] It is understood that once the first clamping member 801 is in place, the second clamping member 803 re-clamps the tape to prevent it from moving backward. Simultaneously, the first elastic member 704 acts on the winding roller 701, causing it to automatically adjust its position around its axis according to the tightness of the tape, thereby continuously tensioning the tape.

[0139] Furthermore, the synchronous detection component 705 counts the number of pulses of the sensor during the detection process, thereby calculating the remaining amount of the tape and determining whether the tape falls off during the pulling process.

[0140] Once the tape is ready for traction, the mobile module automatically adjusts the position of the packaging applicator 100, ensuring that the suction holes of the main applicator 201 and side applicator 301 face the tape, ensuring effective vacuum suction. The mobile module brings the packaging applicator 100 close to the non-adhesive surface of the tape and begins suction. When the vacuum sensor reaches the required vacuum level, the cutting assembly 603 cuts the tape end.

[0141] Furthermore, the packaging and applying device 100 slowly approaches the end face of the coil by moving. When the main applying component 201 of the adhesive tape contacts the end face of the coil, the entire packaging and applying device 100 will continue to move a certain distance, driving the main applying component 201 to move axially relative to the support body 101. Under the action of pressure, the middle part of the adhesive tape is pressed against the packaging film on the end face of the coil. When the packaging and applying device 100 runs to the extreme position, the vacuum suction of the packaging and applying device 100 stops, and at this time, the pressing surface 304 of the side applying component 301 faces the side of the coil. As the side applying components 301 move radially synchronously, the pressing surface 304 gradually contacts the side of the coil, so that the end of the adhesive tape is sealed to the side of the coil.

[0142] After the tape sealing is completed, each side applicator 301 is synchronously moved radially away from the side of the roll material, thereby completing the reset of the side applicator 301.

[0143] In addition, the main applying mechanism and the side applying mechanism absorb the tape by suction, and the cutting component 603 cuts the tape, including but not limited to the following steps:

[0144] The packaging and applying device 100 absorbs a plurality of adhesive tapes, and the packaging and applying device 100 rotates to arrange the adhesive tapes in a crosswise manner.

[0145] In some examples, after the first tape is cut, the packaging and applying device 100 moves away from the pulling and slitting device 600, and the packaging and applying device 100 rotates under the action of the angle adjustment mechanism, so that the packaging and applying device 100 can absorb the second tape in the same manner. It is understood that when the first tape and the second tape are both absorbed by the packaging and applying device 100, the first tape and the second tape are arranged in a cross-shaped manner.

[0146] Furthermore, after the packaging and applying device 100 absorbs the two cross-arranged tapes, the moving module adjusts the position of the packaging and applying device 100 according to the specific shape of the roll material, so that the center of the packaging and applying device 100 is aligned with the center of the roll material, making it easier to seal the tape to the end face of the roll material in the subsequent process.

[0147] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
