The moving member 3 can move towards or away from the fixing member 4 along the linear guide rail 2, so as to quickly and stably align and bond the end faces of the edges of the webs.

[0055] In one embodiment, a guide rail fixing plate is arranged on the base 1, as shown in Figure 4 The plane of the guide rail fixing plate is perpendicular to the plane of the base 1, and the linear guide rail 2 is fixedly arranged on the guide rail fixing plate.

[0057] In an improved embodiment, the number of the linear guide rails 2 is multiple, including but not limited to Figure 4 As shown in the case of two linear guide rails 2, the multiple linear guide rails 2 are parallel and spaced apart. The moving member 3 is connected with the multiple linear guide rails 2 to form multiple-point support, so that the moving process of the moving member 3 towards the fixing member 4 is more stable, and the first web clamping structure 5 on the moving member 3 and the second web clamping structure 6 on the fixing member 4 can be aligned, thereby avoiding affecting the bonding effect. Specifically, the linear guide rail 2 is provided with a sliding connecting piece that can slide along the linear guide rail 2, and the moving member 3 is fixedly connected with the sliding connecting piece.

[0058] In one embodiment, as shown in Figure 3 The linear guide rail 2 is arranged between the fixing member 4 and the guide rail fixing plate, the fixing member 4 is fixedly connected with the linear guide rail 2, and the distance between the fixing member 4 and the guide rail fixing plate is the same as the distance between the moving member 3 and the guide rail fixing plate.

[0059] In one embodiment, as shown in Figure 4As shown, a position adjusting member for adjusting the distance between the fixing member 4 and the guide rail fixing plate is arranged between the fixing member 4 and the guide rail fixing plate, and one end of the linear guide rail 2 can extend into the position adjusting member, so that when the moving member 3 approaches the fixing member 4 along the linear guide rail 2, the first web clamping structure 5 on the moving member 3 can be aligned and attached with the second web clamping structure 6 on the fixing member 4 in the thickness direction of the fixing member 4. The position adjusting member, the fixing member 4 and the guide rail fixing plate are fixedly connected, for example, the fixing member 4 and the position adjusting member are fixedly connected, and the position adjusting member and the guide rail fixing plate are fixedly connected.

[0060] In one embodiment, the linear guide rail 2 can extend into the guide rail limiting structure formed by the position adjusting member and the guide rail fixing plate. In an alternative embodiment, one end of the linear guide rail 2 can extend into the position adjusting member.

[0061] Figure 5 is a perspective view of the first web clamping device provided by the embodiment of the present application, Figure 6 is Figure 5 is a left view of Figure 5 and Figure 6 As shown, the first web clamping structure 5 includes a first clamping member 51, a second clamping member 52 and a baffle 53, the first clamping member 51 and the second clamping member 52 are detachably connected, a clamping gap for accommodating the web 7 is formed between the first clamping member 51 and the second clamping member 52, the first clamping member 51 is connected with the baffle 53, and the baffle 53 is located at the side edge of the first clamping member 51.

[0062] Figures 7-8 is a schematic diagram of the principle of fixing the edge of the web using the first web clamping device provided by the embodiment of the present application, wherein Figure 7 is a perspective view, when fixing the edge of the web using the first web clamping device, the position of the baffle 53 and the first clamping member 51 can be determined first as shown in Figure 7 , then the first clamping member 51 and the second clamping member 52 are connected as shown in Figure 8 , so as to fix the edge of the web in the clamping gap between the first clamping member 51 and the second clamping member 52. The baffle 53 is used to support the end surface of the web edge, one side surface of the web 7 is attached with the first clamping part 511, and the other side surface of the web 7 is attached with the second clamping part 521 (not shown), and the one side surface of the web 7 is arranged opposite to the other side surface of the web 7.

[0063] Figure 9 is a schematic diagram of the position relationship between the first clamping member and the baffle provided by the embodiment of the present application, as shown in Figure 9 The first clamping member 51 includes a first clamping part 511 and two first connecting members 512, the two first connecting members 512 are respectively located at both ends of the first clamping part 511, and the two first connecting members 512 are arranged opposite to each other.

[0064] Figure 10 is a perspective view of a second clamping piece provided by an embodiment of the present application, as Figure 10 shown, the second clamping piece 52 comprises a second clamping portion 521 and two second connecting pieces 522, and the two second connecting pieces 522 are respectively located at two ends of the second clamping portion 521. The first clamping portion 511 is arranged opposite to the second clamping portion 521.

[0065] The first clamping piece 51 and the second clamping piece 52 can be detachably connected through the first connecting piece 512 and the second connecting piece 522.

[0066] In an embodiment, as Figure 9 shown, the two first connecting pieces 512 on the first clamping piece 51 are of the same structure, as Figure 10 shown, the two second connecting pieces 522 on the second clamping piece 52 are of the same structure, and the same structure is conducive to reducing design and production costs.

[0067] In the present embodiment, the web 7 is clamped between the first clamping piece 51 and the second clamping piece 52, and the support and positioning of the web 7 can be achieved in the width direction of the baffle 53. The contact surface of the first clamping piece 51, the second clamping piece 52 and the web 7 is a polished smooth plane structure, which will not cause damage to the web 7 due to clamping.

[0068] In the present embodiment, the baffle 53 is inserted into the web 7 gap close to the end face of the web 7, and the support and positioning of the web 7 can be achieved in the thickness direction of the baffle 53. The contact surface of the first clamping piece 51, the second clamping piece 52 and the baffle 53 and the web 7 is a polished smooth plane structure, which will not cause damage to the web 7 due to clamping.

[0069] When the operator takes and places the web clamping structure, the hands only contact the side of the first clamping portion 511 away from the web 7 and the side of the second clamping portion 521 away from the web 7, without touching the web 7, reducing damage to the product, and avoiding burns on the hands.

[0070] As Figure 9 shown, the side edge of the baffle 53 away from the first clamping portion 511 is provided with a plurality of openings, the positions of the openings are configured to correspond to the glue applying area between the adjacent internal pasting surfaces of the web 7 (the glue applying area other than the end face of the web 7), the length direction of the end face to be pasted of the web 7 is consistent with the length direction of the baffle 53, and the plurality of openings are distributed in the length direction of the baffle 53. A baffle is formed between adjacent openings, and the openings and the baffles are alternately arranged so that the side edge of the baffle 53 away from the first clamping portion 511 is zigzag-shaped, and preferably, the shape of the opening is rectangular, and the shape of the baffle is rectangular.

[0071] In some embodiments, the baffle 53 and the first clamping member 51 are in an integrated structure. The integrated structure is usually obtained by milling the baffle 53 from the same thickness as the first clamping member 51 to the required thickness of the baffle 53. The integrated structure has good stability, but has high processing cost, high processing difficulty, and low production efficiency.

[0072] In some embodiments, as shown in Figure 9 , the baffle 53 and the first clamping member 51 are separately arranged, and the baffle 53 and the first clamping member 51 are detachably connected. Compared with the integrated structure, the separate arrangement scheme can reduce the processing cost and the processing difficulty.

[0073] The baffle 53 and the first clamping member 51 are connected by screws. It should be noted that the above screw connection is only one specific example of the detachable connection mode, and other detachable connection modes can also be applied herein.

[0074] Specifically, as shown in Figure 5 and Figure 6 , the width of the baffle 53 is less than the width of the clamping gap. The width of the baffle 53 refers to the maximum distance from one side edge of the baffle 53 to the other side edge of the baffle 53. The one side edge of the baffle 53 is the above-mentioned side edge of the baffle 53 away from the first clamping portion 511, and the other side edge of the baffle 53 is arranged opposite to the one side edge of the baffle 53 and connected with the first clamping portion 511. The width of the clamping gap is the distance between the first clamping portion 511 and the second clamping portion 521.

[0075] In the present embodiment, the width of the baffle 53 can be set to 0.5-1 times the width of the clamping gap, so as to provide sufficient support for the end face of the web edge.

[0076] In the present embodiment, as shown in Figure 6 and Figure 9 , the first clamping portion 511 can be a plate-shaped structure, and the thickness of the baffle 53 is less than the thickness of the first clamping portion 511. As shown in Figure 6 and Figure 10 , the second clamping portion 521 is a plate-shaped structure, and the thickness of the baffle 53 is less than the thickness of the second clamping portion 521. It should be noted that the first clamping portion 511 and the second clamping portion 521 can also be other shapes, and the present embodiment is not limited thereto.

[0077] It should be noted that the first clamping portion 511 and the second clamping portion 521 are provided with a larger thickness value in order to ensure the strength of the web clamping structure, so as to provide effective and stable support for the clamped web 7, and avoid the deformation of the web 7 under the action of its own gravity or external force in the case of lacking support, thereby affecting the lamination.

[0078] It should be noted that setting a smaller thickness for the baffle 53 is to control the gap between adjacent bonding surfaces within the web 7 within an effective bonding distance. This ensures that the structure of the web 7 itself is not damaged during the bonding process of the two end faces of the web 7, allowing the adhesive areas between adjacent bonding surfaces within the web 7 to bond effectively. The effective bonding distance refers to the maximum distance at which two bonding surfaces can be bonded together with adhesive. When the gap between two bonding surfaces exceeds the effective bonding distance, the two bonding surfaces cannot be bonded together with adhesive. The effective bonding distance is related to the physicochemical properties of the adhesive and can be determined according to actual conditions; this embodiment is not limited to this.

[0079] Specifically, the thickness of the baffle 53 is less than 2mm, the thickness of the first clamping member 51 is 6-15mm, and the thickness of the second clamping member 52 is 6-15mm. For example, the thicknesses of the baffle 53, the first clamping member 51, and the second clamping member 52 are 2mm, 15mm, and 15mm, respectively; as another example, the thicknesses of the baffle 53, the first clamping member 51, and the second clamping member 52 are 0.2mm, 6mm, and 6mm, respectively; as yet another example, the thicknesses of the baffle 53, the first clamping member 51, and the second clamping member 52 are 1mm, 10.5mm, and 11mm, respectively. The thicknesses of the first clamping member 51 and the second clamping member 52 can be the same or different.

[0080] In this embodiment, the thickness range of the baffle 53, the first clamping part 511 and the second clamping part 521 is determined for the case where the web 7 is an automotive air conditioning filter. When the use, material and shape of the web 7 change, the thickness range of the baffle 53 can be re-determined according to actual needs.

[0081] Specifically, the surface of the baffle 53 is a smooth surface, which can prevent burrs, sharp corners and other damage to the web 7.

[0082] like Figure 5 As shown, the first clamping member 51 and the second clamping member 52 are engaged and connected by the first connecting member 512 and the second connecting member 522.

[0083] In one embodiment, such as Figure 9 As shown, the first connector 512 is provided with a locking and positioning part, such as... Figure 10 As shown, the second connector 522 includes a retractable engaging assembly that can be connected to the engaging positioning part. In use, the retractable engaging assembly is engaged with its corresponding engaging positioning part, and the engagement sequence of the two sets of engaging structures is not important.

[0084] Specifically, such as Figure 9As shown, the first connecting piece 512 comprises an end plate connected with the first clamping part 511, and the end plate is provided with a clamping positioning part. The positions of the end plate and the first clamping part 511 can be perpendicular to each other or parallel to each other (for example, both in the same plane).

[0085] In an alternative embodiment, the second connecting piece 522 comprises a clamping positioning part, and the first connecting piece 512 comprises a telescopic clamping assembly connectable with the clamping positioning part.

[0086] In an embodiment, the first clamping piece 51 is provided with a clamping positioning part at each end, and the two clamping positioning parts and the second clamping part 521 are located on the same side of the first clamping part 511. The second clamping piece 52 is provided with a telescopic clamping assembly at each end, and the two telescopic clamping assemblies are arranged on the same side of the second clamping part 521.

[0087] In another embodiment, in order to reduce the cost, the first clamping piece 51 is provided with a clamping positioning part at each end, the second clamping piece 52 is provided with a non-telescopic clamping structure (for example, a buckle 91) at one end, and the other end of the second clamping piece 52 is provided with a telescopic clamping assembly. In use, the non-telescopic clamping structure is first clamped and connected with the corresponding clamping positioning part, and then the telescopic clamping assembly is clamped and connected with the corresponding clamping positioning part.

[0088] The clamping positioning part can be an opening matched with the telescopic clamping assembly. Alternatively, the clamping positioning part can also be a groove or other structure matched with the telescopic clamping assembly.

[0089] Figure 11 is a structural schematic view of the telescopic clamping assembly provided by the embodiment of the present application, as Figure 11 As shown, the telescopic clamping assembly comprises a buckle 91, a seat body 92, a retracting operating piece 93, a return spring 94 and a locking operating piece 95.

[0090] The buckle 91 is slidingly arranged in the seat body 92, and the buckle 91 can extend or retract in the seat body 92 in a first direction. The return spring 94 is connected between the buckle 91 and the seat body 92. The first direction is the telescopic direction of the buckle 91 relative to the seat body 92.

[0091] The buckle 91 is provided with the retracting operating piece 93, which can drive the buckle 91 to move in the first direction to retract the buckle 91 into the seat body 92, and at the same time compress the return spring 94. The retracting operating piece 93 includes but is not limited to a lever. The return spring 94 is used to drive the buckle 91 to extend out of the seat body 92 in the first direction.

[0092] The locking operating member 95 is arranged on the seat body 92 and can move in a second direction to lock or unlock the buckle 91, and the second direction is perpendicular to the first direction.

[0093] In one embodiment, Figures 12-14 is a schematic view of the position relationship between the buckle and the locking operating member provided by the embodiment of the present application, as Figures 12-14 shown, the buckle 91 is provided with a first stop piece 911 and a second stop piece 912, which are arranged in sequence in the direction in which the buckle 91 is retracted into the seat body 92, and a gap for accommodating the locking operating member 95 is formed between the first stop piece 911 and the second stop piece 912, the bottom surface of the first stop piece 911 is the limiting surface thereof, and the bottom surface of the second stop piece 912 is the limiting surface thereof.

[0094] The locking operating member 95 is provided with a locking limiting piece 951 for limiting cooperation with the first stop piece 911 and the second stop piece 912, and the top surface of the locking limiting piece 951 is the limiting surface thereof, as Figure 12 shown, in the locked state, the limiting surface of the locking limiting piece 951 is higher than the limiting surface of the second stop piece 912, and the limiting surface of the locking limiting piece 951 is higher than the limiting surface of the first stop piece 911.

[0095] The locking operating member 95 (for example, a button) can move in the second direction under the action of an external force (for example, pressing) to change the position of the locking limiting piece 951 arranged thereon, thereby changing the height of the limiting surface of the locking limiting piece 951, so as to switch the buckle 91 between the locked state and the unlocked state.

[0096] As Figure 13 shown, when the limiting surface of the locking limiting piece 951 drops to a position lower than the limiting surface of the second stop piece, the buckle 91 enters the unlocked state. As Figure 14 shown, in the unlocked state, the limiting surface of the locking limiting piece 951 is lower than the limiting surface of the second stop piece 912. When the limiting surface of the locking limiting piece 951 is lower than the limiting surface of the second stop piece, the locking limiting piece 951 no longer blocks the movement of the buckle 91 in the direction of extending into the seat body 92, and the buckle 91 moves in the direction of extending into the seat body 92 under the pushing of the return spring 94.

[0097] The buckle 91 moves in the direction of extending into the seat body 92 under the pushing of the return spring 94 and covers the limiting surface of the locking limiting piece below the limiting surface of the second stop piece, so that the buckle 91 remains unchanged in the ejected state.

[0098] The telescopic clamping assembly utilizes the height difference between the limiting surface of the locking limiting piece 951 and the surface of the buckle 91, and the buckle 91 is quickly extended or retracted by the return spring 94 and the retracting operating member 93, so that the tooling fixture is installed and disassembled faster.

[0099] Figure 15 is a bottom view of the telescopic clamping assembly provided by an embodiment of the present application, as shown in one embodiment, the seat body 92 is provided with a third limiting structure 921, and the buckle 91 is provided with a fourth limiting structure 913. The third limiting structure 921 and the fourth limiting structure 913 are arranged in correspondence in the telescopic direction of the buckle 91, and can cooperate with each other to limit the maximum extension position of the buckle 91. The third limiting structure 921 includes a protrusion, and the fourth limiting structure 913 includes an opening or a groove, the protruding direction of the protrusion is adapted to the recessed direction of the opening or the groove. Figure 15

[0100] In one embodiment, the buckle 91 is provided with a stepped structure, as shown in any one of Figures 11-14 , the stepped structure includes a first step and a second step, the first step can extend into the opening of the clamping positioning part, and the second step can cooperate with the clamping positioning part to limit the maximum extension position of the buckle 91.

[0101] In one embodiment, as shown in any one of Figures 11-14 , the proximal end of the buckle 91 is provided with an opening for accommodating the reset spring 94, and the length direction of the opening is arranged along the telescopic direction of the buckle 91 (the telescopic direction of the reset spring 94).

[0102] In one embodiment, as shown in any one of Figure 7 , Figure 9 and Figure 16 , the first clamping part 51 is further provided with a foolproof structure, as shown in Figure 10 , the second clamping part 52 is provided with a foolproof structure. The foolproof structure includes any one or a combination of a plurality of protruding structures, recessed structures and planar structures, and can be a directional identification structure, the shape of which includes but is not limited to an arrow, and can also be other graphics or characters.

[0103] In one embodiment, the telescopic clamping assembly further includes a shell, one side of the shell towards the end of the second clamping part 52 can be used as the above-mentioned limiting part. The pressed end of the pressing part extends out of the shell, and the actuating end of the actuating part extends out of the shell, and the pressing part and the actuating part are arranged on the same side of the shell. The shell can play a role in positioning the buckle, the retracting operating part and the locking operating part, and can also shield the internal structure of the telescopic clamping assembly, play a role in dust prevention and aesthetics, and also avoid scratching other objects by the components of the telescopic assembly, including but not limited to the to-be-clamped part, such as the web 7.

[0104] The setting position of the foolproof structure includes but is not limited to the side of the first clamping part 511 close to the web 7 (as shown in Figure 9 , the side of the first clamping part 511 away from the web 7 (as shown in Figure 1 ​As shown, the location of the anti-foolproof structure includes, but is not limited to, the side of the second clamping part 521 that is in contact with the web 7 (not shown) and the side of the second clamping part 521 that is away from the web 7. In this way, the correct placement direction of the web clamping structure can be easily distinguished from either side, and it will not be upside down, thus avoiding the incorrect placement direction of the web clamping structure.

[0105] In some embodiments, such as Figure 1 As shown, each of the first clamping parts 511 is provided with at least one foolproof structure, such as Figure 10 As shown, the second clamping part 521 is provided with at least one foolproof structure. The at least one foolproof structure is provided on the side of the first clamping part 511 away from the web 7, or the at least one foolproof structure is provided on the side of the second clamping part 521 away from the web 7. In this way, when the web 7 is clamped in the clamping gap, even if the web 7 is in close contact with the first clamping part 511 and the second clamping part 521 and blocks the foolproof structure provided on the inside, the operator can still distinguish the correct placement direction of the web clamping structure by the foolproof structure provided on the outside of the web clamping structure.

[0106] In one embodiment, the end of the first web clamping structure 5 is provided with a first limiting structure, and the base 1 is provided with a second limiting structure 11. Figure 16 This is a schematic diagram of the web edge bonding device under dispensing conditions provided in an embodiment of the present invention. Figure 17 This is a top view showing the positional relationship between the web edge bonding device and the web under the dispensing state provided in the embodiment of the present invention, as shown below. Figure 16 and Figure 17 As shown, the first limiting structure and the second limiting structure 11 cooperate to limit the first web clamping structure 5 to be positioned at a predetermined glue dispensing position on the base 1.

[0107] In one embodiment, one end of the first web clamping structure 5 is provided with a first limiting structure, while the other end is not provided with a first limiting structure. This is beneficial for distinguishing the correct placement direction of the web clamping structure and avoiding incorrect placement of the web clamping structure.

[0108] In one embodiment, such as Figure 9 As shown, the first limiting structure includes several positioning grooves, and the second limiting structure 11 includes several positioning protrusions. The several positioning grooves match the several positioning protrusions, thereby quickly adjusting the relative position of the web clamping structure and the second limiting structure 11 to ensure that the web clamping structure can be quickly and accurately installed into or removed from the predetermined dispensing position on the base 1.

[0109] Specifically, several positioning grooves are provided along at least one edge of the end of the web clamping structure. Figure 18 This is a schematic diagram of a second limiting structure 11 provided in an embodiment of the present invention, as shown below. Figure 18As shown, the positioning grooves are arranged along two opposite edges of the second limiting structure 11, and it is also possible that the positioning grooves are arranged along two adjacent edges of the second limiting structure 11.

[0110] In one embodiment, one end of the first web clamping structure 5 is provided with a first limiting structure and a magnetic suction member, as shown in the accompanying drawings. Figure 18 As shown, the base 1 is provided with a second limiting structure 11 and a magnetic member, which are matched with each other to limit the first limiting structure. The magnetic member is arranged within the range defined by the second limiting structure 11. The mutual attraction between the magnetic suction member and the magnetic member can avoid the web clamping structure from being tilted under the action of external force during the dispensing process. The magnetic member includes but is not limited to a magnet, and the magnetic suction member includes but is not limited to an iron block. The magnetic member can adopt an integrated structure or a split structure. In the scheme of adopting the integrated structure, a whole magnet is arranged at the first predetermined position, which is simple in structure and easy to install. In the scheme of adopting the split structure, a plurality of small magnetic members are arranged at the first predetermined position, which are arranged in an array. The advantage is that the attraction force can be adjusted by adjusting the number and distribution position of the small magnetic members, and under the premise of ensuring the stability of the connection between the web clamping structure and the base 1, the force required by the operator to plug in or pull out the web clamping structure is minimized. The disadvantage is that the structure is complex and the cost is slightly high.

[0111] Specifically, when other structures are also arranged at the preset dispensing position, the shape of the second limiting structure 11 can be adapted to the other structures on the base 1, and the embodiments of the present application are not limited thereto.

[0112] In some embodiments, the moving member 3 is provided with a first positioning member 31 for limiting / positioning the first web clamping structure 5, and the fixing member 4 is provided with a second positioning member 41 for limiting / positioning the second web clamping structure 6. Optionally, the positions of the first positioning member 31 on the moving member 3 and the second positioning member 41 on the fixing member 4 are symmetrical to each other.

[0113] The first web clamping structure 5 includes a third positioning member 523 arranged on the side of the second clamping part 521 of the first web clamping structure 5 away from the first clamping part 51. The second web clamping structure 6 includes a fourth positioning member, and the positions of the fourth positioning member on the second web clamping structure 6 and the third positioning member 523 on the first web clamping structure 5 are symmetrical to each other.

[0114] Preferably, the first positioning member 31 is positioned at the same position on the moving member 3 as the second positioning member 41 on the fixing member 4, and the fourth positioning member on the second web clamping structure 6 is positioned at the same position as the third positioning member 523 on the first web clamping structure 5, so that the first web clamping structure 5 positioned by the first positioning member 31 is also aligned with the second web clamping structure 6 positioned by the second positioning member 41, and after alignment, the moving member 3 can be moved along the linear guide rail to approach the fixing member and adhere to the two to-be-positioned members fixed thereon.

[0115] The first positioning member 31 is magnetically attached to the third positioning member 523, and the second positioning member 41 is magnetically attached to the fourth positioning member, so as to realize quick assembly and disassembly.

[0116] In some cases, the web 7 needs to be carried and moved during dispensing and adhering, and the magnetic member provided on the web clamping structure may be attracted by iron filings during carrying and moving, thereby causing the installation position of the web clamping structure to deviate, affecting alignment and / or connection stability, and affecting the adhering effect. Therefore, preferably, the third positioning member 523 and the fourth positioning member are provided with magnetic attraction members, which can avoid the attraction of iron filings during the stacking and carrying of the web clamping structure, thereby affecting the alignment. The first positioning member 31 and the second positioning member 41 are provided with matching magnetic members, which can adopt an integrated structure or a split structure. The specific implementation mode and advantages and disadvantages of the integrated structure or the split structure are described in the foregoing embodiments, which will not be described here.

[0117] Preferably, the first clamping member 51, the second clamping member 52, and the baffle 53 are made of one or more of aluminum, iron, and copper. The above materials are easy to process and low in cost, and the web clamping structure processed therefrom meets the requirements of high temperature resistance, light weight, easy plugging and unplugging, sufficient rigidity to support the web 7, etc.

[0118] The second web clamping structure 6 is provided at a predetermined dispensing position on the base 1, and the dispensing surface of the web edge faces the side of the base 1 provided with a long strip-shaped opening. It should be noted that the dispensing surface can also face other directions that are convenient for dispensing, which is not limited in the present embodiment.

[0119] After dispensing is completed, the second web clamping structure 6 is installed on the fixing member 4 to complete the alignment and adhesion of the end surface of one web edge with the end surface of the other web edge. The dispensing surface of the to-be-positioned member faces the to-be-positioned member on the moving member 3, and moving the moving member 3 along the linear guide rail 2 towards the fixing member 4 can quickly and stably align and adhere the end surface of one web edge with the end surface of the other web edge.

[0120] In one embodiment, the base 1 is provided with a web unwinding auxiliary structure, which is arranged on the other side of the linear guide rail 2 opposite to the one side of the linear guide rail 2, thereby providing convenience for the operator to unwind the web 7.

[0121] In order to avoid damaging the web 7, the web unwinding auxiliary structure should be polished smooth without sharp corners and burrs, and preferably, the outer contour of the web unwinding auxiliary structure can be an arc surface, and can also be other curved surfaces with smooth cross-sectional contours such as clover-shaped, shell-shaped and the like.

[0122] In one embodiment, the web unwinding auxiliary structure comprises a first support plate 81, a second support plate 82 and at least one third connecting piece 83, one end of the at least one third connecting piece 83 is fixedly connected with the first support plate 81, the other end of the at least one third connecting piece 83 is fixedly connected with the second support plate 82, and the first support plate 81 is arranged on the side of the second support plate 82 away from the base 1.
