[0015] From the above description of the present application, compared with the prior art, the present application has the following beneficial effects:
[0016] The technical scheme one provides a splicing jig for film materials, which comprises a body, a fixing member and a limiting assembly, a head of a new film material and a tail of an old film material are placed on the body in the same direction, then the fixing member is turned to cover the body and press against the film materials placed on the body, and the head edge of the new film material and the tail edge of the old film material are exposed to the cutting flange of the body at the same time, then a cutter is used to cut the two film materials along the cutting flange at the same time to form a consistent splicing edge, then an adhesive tape is pasted on one side of one of the film materials, and the adhesive tape is folded to paste the adhesive tape on the other side of the other film material, then the fixing member is opened, and the two film materials connected together can be taken out; in the process, the limiting assembly plays a role of limiting one side of the film material in the width direction, after the two film materials are placed on the body in layers, the first side in the width direction of the film material abuts against the body, at this time, the position of the bolt in the limiting assembly can be adjusted along the first sliding groove and the second sliding groove, so that the bolt abuts against the second side in the width direction of the film material, thereby the film material is positioned in the width direction to avoid position deviation of the film material in the cutting process; through the position-adjustable limiting assembly, the splicing jig can be adapted to film materials of different width sizes, the new and old film materials are conveniently spliced, and gaps are not prone to existing at the splicing position.
[0017] In the technical scheme two, the limiting assembly comprises a sliding block, the sliding block comprises a sliding part and a lapping part, the sliding block is located in the second sliding groove and is in sliding fit with the second sliding groove, and the limiting assembly can be prevented from shaking due to the size mismatch with the second sliding groove and the first sliding groove; the lapping part is lapped on the fixing member, so that the sliding block and the fixing member form limiting in the upward and downward directions to prevent the sliding block from falling off; meanwhile, the nut of the bolt is lapped on the lapping part of the sliding block, and the bolt also forms limiting in the upward and downward directions with the fixing member to prevent the bolt from falling off.
[0018] In the technical scheme three, a bearing surface is arranged on the body, and a pressing surface is arranged on the fixing member, the two surfaces cooperate with each other, the film material can be positioned on the jig through the opening and covering actions of the fixing member; wherein a limiting part is protruded on the bearing surface at a position close to the first axis, the limiting part can cooperate with the limiting assembly to limit the film material in the front and back directions, that is, in the width direction of the film material; the limiting part can form a gap with a certain size between the pressing surface and the bearing surface after the fixing member is covered on the body, so as to prevent the film material from being damaged due to shearing when the fixing member is covered on the body.
[0019] In the technical scheme four, the limiting surface of the limiting part faces the front end of the bearing surface, so that one side edge of the film material in the width direction can abut against the limiting part.
[0020] In the fifth aspect, the lower end surface of the sliding part of the sliding block is inclined, and the rear edge of the lower end surface is higher than the bearing surface when the fixing member is covered on the body. In this way, when the limiting assembly positions the side edge of the film material in the width direction by moving its position, the side edge of the film material is positioned on the lower end surface of the sliding part instead of the rear surface of the sliding part. The lower end surface of the sliding part exerts force on the edge of the film material in the up-down direction and the front-rear direction, so that the film material is more evenly stressed when it is positioned on the sliding block. This can avoid the film material from being folded or the edge from being warped when it is positioned on the limiting assembly, and reduce damage to the film material.
[0021] In the sixth aspect, the nut can be rotated by the shape characteristics of the long side and the short side. When the fixing member is covered on the body and needs to be fixed, the long side abuts against the body to fix the fixing member and the body as a whole. When the fixing member needs to be opened, the short side allows the nut to pass through the first sliding groove and the second sliding groove. In this way, the nut does not need to be removed from the bolt, and the limiting assembly can move with the fixing member, so that the operation of the jig is more convenient.
[0022] In the seventh aspect, two first installation grooves are arranged on the body, and a first foam strip is arranged in the first installation groove. The first foam strip improves the friction between the bearing surface and the film material, so that the film material is not displaced when it is cut, and the splicing edges are not uneven.
[0023] In the eighth aspect, two second installation grooves are arranged on the fixing member, and a second foam strip is arranged in the second installation groove. The second foam strip cooperates with the first foam strip to improve the friction on the film material when the fixing member is covered on the body, so that the film material is not displaced when it is cut, and the splicing edges are not uneven.
[0024] In the ninth aspect, a buckling member is fixed to the front end of the fixing member. The front end of the fixing member is buckled to the body through the buckling member to achieve preliminary positioning. Then, the position of the limiting assembly is adjusted, and the fixing member and the body are locked as a whole through the bolt and the nut of the limiting assembly.
[0025] In the tenth aspect, a hinge is arranged at the rear end of the body and the fixing member. The hinge connects the body and the fixing member to rotate around the first axis. BRIEF DESCRIPTION OF DRAWINGS

[0042] Referring to Figure 1 The splicing jig includes a body 10, a fixing member 20, a limiting assembly 30 and a hinge 40. As shown in the coordinate Figure 1 The front-rear direction, left-right direction and up-down direction referred to in the specification and claims are indicated. It should be noted that since the fixing member 20 can rotate relative to the body 10 to open and close, the description of the up-down direction of the fixing member 20 is based on the fixing member 20 in the closed state.
[0043] The splicing jig, the body 10 extends along the front and back directions and is suitable for placing the film material, and is provided with a first sliding groove 11 and a cutting flange 12; the first sliding groove 11 extends along the front and back directions and penetrates the body 10 along the up and down directions; the cutting flange 12 extends along the front and back directions and is located on one side of the body 10 along the left and right directions, so that the cutter cuts the film material along the extension direction of the cutting flange 12; the fixing part 20 extends along the front and back directions and is rotatably connected to the body 10 around the first axis, and is suitable for covering the body 10 to press against the film material placed on the body 10, or opening from the body 10 to be out of contact with the film material placed on the body 10; the fixing part 20 is provided with a second sliding groove 21 corresponding to the first sliding groove 11, the second sliding groove 21 extends along the front and back directions and penetrates the fixing part 20 along the up and down directions; the limiting assembly 30 includes a bolt 31 and a nut 32, the bolt 31 penetrates the first sliding groove 11 and the second sliding groove 21 to slide along the front and back directions, and is suitable for screwing with the nut 32 to be fixed to the body 10 and the fixing part 20; the body 10 and the fixing part 20 are rotatably connected through the hinge 40 located at the rear ends of the two.
[0044] Wherein, the upward side surface of the body 10 forms a bearing surface 13, the bearing surface 13 is used for placing the film material; the downward side surface of the fixing part 20 forms a pressing surface 22, the pressing surface 22 is used for pressing the film material placed on the bearing surface 13; the bearing surface 13 is protruded to form a limiting part 14 at the position close to the first axis, the limiting part 14 is suitable for cooperating with the limiting assembly 30 to position the film material in the front and back directions. The limiting part 14 is provided with a limiting surface 141 extending along the left and right directions towards the front end of the bearing surface 13.
[0045] And, the body 10 is recessed to form a first mounting groove 15 on the left and right sides of the first sliding groove 11 by the bearing surface 13, both the first mounting grooves 15 extend along the first direction, and are mounted with a first foam strip, the upper side surface of the first foam strip is flush with the bearing surface 13. The fixing part 20 is recessed to form a second mounting groove 23 on the left and right sides of the second sliding groove 21 by the pressing surface 22, both the second mounting grooves 23 extend along the first direction, and are mounted with a second foam strip, the lower side surface of the second foam strip is flush with the pressing surface 22.
[0046] In addition, the front end of the fixing part 20 is provided with a buckling part 24, the buckling part 24 is used for locking and connecting with the front end of the body 10 when the fixing part 20 covers the body 10.
[0047] Specifically, referring to Figure 1 In this embodiment, the body 10 is a long strip plate-like member, and the length direction thereof is also the extension direction thereof, which isFigure 1 The upper side surface of the body 10 forms a bearing surface 13 for placing the film material, and a first sliding groove 11 is provided at the middle position of the left-right direction of the body 10 and extends in the front-rear direction. The first sliding groove 11 penetrates the upper side surface and the lower side surface of the body 10 in the up-down direction, and the two ends in the front-rear direction are close to the two ends of the body 10 in the front-rear direction. Two first mounting grooves 15 are respectively provided on the left and right sides of the first sliding groove 11, which also extend in the front-rear direction. The first mounting grooves 15 are open at the front-rear ends and can be used to mount a first foam strip with a size matching that of the first mounting grooves 15. The thickness of the first foam strip matches the depth of the groove, so that the upper side surface of the first foam strip can be flush with the bearing surface 13 of the body 10 to increase the friction on the surface of the film material and prevent the film material from being displaced during cutting.
[0048] A cutting flange 12 is provided on the left edge of the body 10. The cutting flange 12 can be considered as a protrusion formed outward from the left edge of the body 10 and extends in the front-rear direction. The cutting flange 12 forms a stepped structure with the bearing surface 13 of the body 10. After the film material is placed on the jig, the film material can be cut by a cutter closely attached to the cutting edge to limit the cutting direction of the cutter and prevent the splicing edge of the film material from being uneven.
[0049] Referring to Figure 1 and Figure 4 A limiting portion 14 protruding from the bearing surface 13 is provided at the rear end of the body 10. The front side surface of the limiting portion 14 forms a limiting surface 141. After the film material is placed on the bearing surface 13 of the body 10, the film material can be pushed backward to abut against the limiting surface 141 of the limiting portion 14. The bearing surface 13 and the pressing surface 22 of the fixing member 20 are matched with each other. The film material can be positioned on the jig through the opening and closing actions of the fixing member 20. The limiting portion 14 is protruding at the position close to the first axis of the bearing surface 13. The limiting portion 14 can be matched with the limiting assembly 30 in the front-rear direction, that is, the width direction of the film material, to limit the film material. The limiting portion 14 can form a gap with a certain size between the pressing surface 22 and the bearing surface 13 after the fixing member 20 is closed to the body 10, so as to avoid damage to the film material due to shearing when the fixing member 20 is closed to the body 10. The limiting surface 141 of the limiting portion 14 faces the front end of the bearing surface 13, which is convenient for the side edge in the width direction of the film material to abut against the limiting portion 14.
[0050] Referring to Figure 1In this embodiment, the fixing member 20 is a long strip-shaped component with approximately the same shape and size as the body 10, and its length direction is also its extension direction. Figure 1 The front-back direction is shown. The lower surface of the fastener 20 forms a pressing surface 22 for engaging with the body 10 to press against the film material. Simultaneously, at the midpoint of the fastener 20 in the left-right direction, a second groove 21 extends in the front-back direction. The second groove 21 penetrates both the upper and lower surfaces of the fastener 20 in the vertical direction, with its two ends in the front-back direction close to the two ends of the fastener 20 in the front-back direction. Furthermore, the length, position, and width of the second groove 21 are consistent with or correspond to the first groove 11 on the body 10. Two second mounting grooves 23 are provided on the left and right sides of the second groove 21, respectively. These two second mounting grooves 23 also extend in the front-back direction. The second mounting grooves 23 are recessed grooves with open front and rear ends. The second foam strip that matches the size of the second mounting groove 23 can be installed into the second mounting groove 23. The thickness of the second foam strip matches the depth of the recess, so that the upper surface of the second foam strip can be flush with the pressing surface 22 of the fixing member 20 to increase the friction on the surface of the film material. At the same time, through cooperation with the first foam strip on the body 10, the friction on the film material is increased when the fixing member 20 covers the body 10, so as to avoid the film material from shifting under force during cutting and causing uneven splicing edges.
[0051] A hinge 40 is provided at the rear end of the body 10 and the fixing member 20. The two movable leaves of the hinge 40 are respectively connected to the body 10 and the fixing member 20. The pivot of the hinge 40 forms the rotation axis of the body 10 and the fixing member 20. This rotation axis is the first axis of rotation of the fixing member 20 around the body 10. Through the hinge 40, the fixing member 20 can rotate and open relative to the body 10. When a film material is placed on the bearing surface 13 of the body 10, the fixing member 20 can be rotated to cover the body 10. At this time, the bearing surface 13 and the pressing surface 22 cooperate to apply force to the film material, so that the film material can be relatively positioned between the body 10 and the fixing member 20.
[0052] Furthermore, a fastening structure is provided at the front end of the main body 10 and the fixing member 20. The fastening structure includes the fastening member 24 installed at the front end of the fixing member 20 as described above. The fastening member 24 is rotatably installed at the front end of the fixing member 20. In addition, it also includes a fastening protrusion 16 provided at the front end of the main body 10. The fastening member 24 is provided with a fastening hole 25 that matches the position and size of the fastening protrusion 16. After the fixing member 20 is covered to the main body 10, the fastening member 24 can be flipped onto the fastening protrusion 16 and the fastening protrusion 16 can be inserted into the fastening hole 25, so that the fixing member 20 is locked onto the main body 10.
[0053] Reference Figure 1The limiting assembly 30 further comprises a sliding block 33. The sliding block 33 comprises a sliding portion 34 and an overlapping portion 35. The sliding portion 34 is located in the second sliding groove 21 and is adapted to slide along the extending direction of the second sliding groove 21. The overlapping portion 35 overlaps the fixing member 20 in the up-down direction. The bolt 31 penetrates the sliding block 33, and the nut of the bolt 31 overlaps the overlapping portion 35 of the sliding block 33. The lower end surface 36 of the sliding portion 34 of the sliding block 33 is inclined from top to bottom and from back to front. When the fixing member 20 covers the body 10, the rear edge of the lower end surface 36 is higher than the bearing surface 13. The limiting portion 14 is located at the rear end of the bearing surface 13.
[0054] The shape of the nut 32 in the projection plane perpendicular to the rotation axis of the nut 32 has a long side and a short side. The size of the long side is greater than the groove width of the first sliding groove 11, and the size of the short side is less than the groove width of the first sliding groove 11. When the nut 32 is rotated to the corresponding position, the nut 32 is locked with the body 10 or passes through the first sliding groove 11 when the fixing member 20 is opened from the body 10.
[0055] Specifically, referring to Figure 1 In the embodiment, the limiting assembly 30 comprises a bolt 31, a nut 32 and a sliding block 33. The bolt 31 is provided with a threaded shank and a nut. The threaded shank can be threadedly connected with the nut 32. The sliding block 33 is sleeved on the threaded shank of the bolt 31 and is clamped with the nut of the bolt 31 through the overlapping portion 35 on the sliding block 33. The sliding block 33 comprises a sliding portion 34 and an overlapping portion 35. The sliding portion 34 is located below the overlapping portion 35 and is integrally formed with the overlapping portion 35 to form the sliding block 33. The size of the sliding portion 34 in the left-right direction is adapted to the width of the second sliding groove 21. The size of the overlapping portion 35 in the left-right direction is greater than the width of the second sliding groove 21. Therefore, the overlapping portion 35 can overlap the upper side surface of the fixing member, and the sliding portion 34 can extend into the second sliding groove 21, so that the sliding block 33 can slide along the extending direction of the second sliding groove 21. Since the nut 32 is threadedly connected with the bolt 31, the sliding block 33 is actually limited by the nut 32 and the nut of the bolt 31. The sliding block 33 will not fall off from the second sliding groove 21.
[0056] Moreover, the lower end surface 36 of the sliding portion 34 is inclined from back to front from top to bottom, and the rear edge of the lower end surface 36 is higher than the bearing surface 13 when the fixing member 20 is covered to the body 10. In this way, when the limiting assembly 30 positions the side edge of the film material in the width direction by moving its own position, the side edge of the film material is positioned against the lower end surface 36 of the sliding portion 34 instead of the rear surface of the sliding portion 34. The lower end surface 36 of the sliding portion 34 exerts force on the edge of the film material in the up-down direction and the front-rear direction, so that the force on the film material is more uniform when the film material is positioned against the sliding block 33. This can avoid the film material from being folded or the edge of the film material from being warped when the film material is positioned against the limiting assembly 30, and reduce damage to the film material.
[0057] The nut 32 is roughly rectangular in shape, that is, the nut 32 has opposite long sides and short sides. The long sides are larger than the slot width of the first sliding slot 11, and the short sides are smaller than the slot width of the first sliding slot 11. By rotating the nut 32, the nut 32 can be switched between a position intersecting the first sliding slot 11 and a position capable of being accommodated by the first sliding slot 11. When the fixing member 20 is covered to the body 10 and needs to be fixed, the long sides abut against the body 10 to fix the fixing member 20 and the body 10 as a whole. When the fixing member 20 needs to be opened, the short sides enable the nut 32 to pass through the first sliding slot 11 and the second sliding slot 21. In this way, the nut 32 does not need to be detached from the bolt 31, and the limiting assembly 30 can move with the fixing member 20, so that the operation of the jig is more convenient.
[0058] Referring to Figure 2 and Figure 3In use of the splicing jig, the head of the new film material and the tail of the old film material can be placed on the body 10 in the same direction, then the fixing member 20 is turned to cover the body 10 and press against the stacked film materials, and the head edge of the new film material and the tail edge of the old film material are exposed to the cutting flange 12 of the body 10 at the same time, then the cutter is used to cut the two film materials along the cutting flange 12 at the same time to form a consistent splicing edge, then the adhesive tape is pasted on one side of one of the film materials, and the adhesive tape is folded to paste the adhesive tape on the other side of the other film material, then the fixing member 20 is opened, and the two film materials connected together can be taken out; in the process, the limiting assembly 30 plays a role of limiting one side of the film material in the width direction, and after the two film materials are placed on the body 10, the first side in the width direction will abut against the body 10, at this time, the position of the bolt 31 in the limiting assembly 30 can be adjusted along the first sliding groove 11 and the second sliding groove 21, so that the bolt 31 abuts against the second side in the width direction of the film material, thereby positioning the film material in the width direction to avoid position deviation of the film material in the cutting process; through the position-adjustable limiting assembly 30, the splicing jig can adapt to film materials of different width sizes, facilitate splicing of the new and old film materials, and gaps are not easy to exist at the splicing position.
