[0035] like Figures 1 to 5 As shown, the present invention provides a shaping paper splicing glue cutting device, comprising a U-shaped splicing glue holder 100 , a U-shaped blade holder 200 and a cutting blade 300 .

[0036] Among them, a positioning hole 110 is formed on one side wall of the splicing glue bracket 100, and a positioning pin 120 is passed through the positioning hole 110. The length of the positioning pin 120 extending from the positioning hole 110 can be adjusted. An adjustment slot 130 is formed at the end of the splicing glue bracket 100. A limiting hole 210 is formed on one side wall of the blade bracket 200, and a limiting pin 220 is passed through the limiting hole 210. The length of the limiting pin 220 extending from the limiting hole 210 can be adjusted. A circular hole 230 is formed at the end of the blade bracket 200, and an adjustment pin 240 is passed through the circular hole 230. The position of the adjustment pin 240 is adjustable along the extension direction of the adjustment slot 130. The cutting blade 300 is arranged in the U-shaped opening of the blade bracket 200, and the limiting pin 220 clamps the cutting blade 300 with the other side wall of the blade bracket 200. For example, the positioning hole 110 and the limiting hole 210 can be threaded holes, and the positioning pin 120 and the limiting pin 220 can be bolts.

[0037] The shaping paper splicing glue cutting device provided by the present invention is provided with a U-shaped splicing glue holder 100, the splicing glue 10 to be cut is inserted into the U-shaped opening of the splicing glue holder 100, the positioning pin 120 is inserted into the inner circle of the splicing glue 10 to be cut, the operator operates the adjusting pin 240 to adjust the position of the sliding groove 130 to adjust the position of the blade holder 200 relative to the splicing glue holder 100, the blade holder 200 moves to the position of the pre-cutting width with the cutting blade 300, the operator continuously presses the blade holder 200 with the hand, and then squeezes and cuts the tape surface of the splicing glue 10 to be cut with the blade edge of the cutting blade 300, and then pulls the splicing glue holder 100, so that the splicing glue holder 100 rotates along the inner circle of the splicing glue 10 to be cut relative to the splicing glue 10 to be cut, and the blade edge of the cutting blade 300 cuts a cutting mark of the required width on the circumference of the tape surface of the splicing glue 10 to be cut. When in use, the tape that meets the width after cutting can be directly torn off, which can better cope with the different widths of splicing glue required by different forming paper widths, and can improve the splicing glue cutting efficiency and cutting effect.

[0038] In some embodiments, the splicing glue holder 100 includes an I-shaped support arm 140 and an L-shaped support arm 150. The positioning hole 110 is defined in the I-shaped support arm 140. A first wedge-shaped slider 141 is provided at one end of the I-shaped support arm 140. A first dovetail groove 151 is defined along the horizontal section of the L-shaped support arm 150 along its extension direction, which slidably engages with the first wedge-shaped slider 141. The position of the first wedge-shaped slider 141 within the first dovetail groove 151 is adjustable, and an adjustment groove 130 is defined in the horizontal section of the L-shaped support arm 150. With this structure, the first wedge-shaped slider 141 can adjust the distance between the vertical sections of the I-shaped support arm 140 and the L-shaped support arm 150 when sliding relative to the first dovetail groove 151, thereby accommodating splicing glue 10 to be cut within a certain width range.

[0039] Optionally, a first limiting bolt 152 is threadedly connected to the side of the horizontal section of the L-shaped support arm 150 facing away from the first dovetail groove 151. The first limiting bolt 152 can press against the first wedge-shaped slider 141. By providing the first limiting bolt 152, after the position of the I-shaped support arm 140 is adjusted, the first limiting bolt 152 is tightened, and the end of the first limiting bolt 152 presses against the first wedge-shaped slider 141, thereby increasing the friction between the first wedge-shaped slider 141 and the first dovetail groove 151, thereby achieving a certain fixing effect. Of course, in other embodiments, the U-shaped splicing adhesive bracket 100 can also be manufactured in one piece.

[0040] To facilitate the operator to control the position of the blade holder 200 relative to the splicing glue holder 100, a scale 160 is provided at the end of the splicing glue holder 100. The scale 160 is provided along the extension direction of the adjustment slot 130. For example, the scale 160 can be, but is not limited to, laser engraved on the end of the splicing glue holder 100.

[0041] In some embodiments, the blade holder 200 includes an I-shaped support member 250 and an L-shaped support member 260, one end of the I-shaped support member 250 is fixedly connected to the horizontal section of the L-shaped support member 260, the limiting hole 210 is opened on the I-shaped support member 250, the limiting pin 220 and the vertical section of the L-shaped support member 260 clamp the cutting blade 300, and the circular hole 230 is opened in the horizontal section of the L-shaped support member 260.

[0042] Optionally, a second wedge-shaped slider 251 is provided at one end of the I-shaped support member 250, and a second dovetail groove 261 is provided along the extension direction of the horizontal section of the L-shaped support member 260 for sliding cooperation with the second wedge-shaped slider 251. The position of the second wedge-shaped slider 251 in the second dovetail groove 261 is adjustable, and a second limiting bolt 262 is threadedly connected to the side of the horizontal section of the L-shaped support member 260 that is away from the second dovetail groove 261, and the second limiting bolt 262 can press against the second wedge slider 251. Through the above structure, the second wedge-shaped slider 251 can adjust the distance between the vertical sections of the I-shaped support member 250 and the L-shaped support member 260 when sliding relative to the second dovetail groove 261, thereby adapting to cutting blades 300 within a certain width range. By providing a second limiting bolt 262, after the position of the I-shaped support member 250 is adjusted, the second limiting bolt 262 is tightened, and the end of the second limiting bolt 262 presses against the second wedge-shaped slider 251, thereby increasing the friction between the second wedge-shaped slider 251 and the second dovetail groove 261, thereby achieving a certain fixing effect. Of course, in other embodiments, the U-shaped blade holder 200 can also be made of an integral mold.

[0043] In some embodiments, there are two circular holes 230, which are spaced apart at the ends of the blade holder 200. The above structure can prevent the blade holder 200 from swinging relative to the splicing glue holder 100 and affecting the cutting effect.

[0044] In some embodiments, the adjustment pin 240 includes a cylindrical section and an elliptical section 241 coaxially arranged in sequence. The cylindrical section is rotatably connected to the circular hole 230, and the elliptical section 241 is located in the adjustment slot 130. The major axis end of the elliptical section 241 has an interference fit with the adjustment slot 130, and the minor axis end of the elliptical section 241 has a clearance fit with the adjustment slot 130. With the above structure, when the position of the blade holder 200 relative to the splicing glue holder 100 needs to be adjusted, the operator rotates the adjustment pin 240 so that the minor axis end of the elliptical section 241 approaches the side wall of the adjustment slot 130. At this time, the elliptical section 241 has a clearance fit with the adjustment slot 130, allowing the adjustment pin 240 to slide relative to the adjustment slot 130. After the adjustment is completed, the operator rotates the adjustment pin 240 so that the major axis end of the elliptical section 241 presses against the side wall of the adjustment slot 130. At this time, the elliptical section 241 has an interference fit with the adjustment slot 130, and the elliptical section 241 is confined in the adjustment slot 130.

[0045] The working principle of the shaping paper splicing glue cutting device provided by the present invention is as follows:

[0046] The operator first places the cutting blade 300 in the U-shaped opening of the blade holder 200, adjusts the limit pin 220 so that the limit pin 220 and the vertical section of the L-shaped support 260 clamp the cutting blade 300, and then extends the splicing glue 10 to be cut into the U-shaped opening formed by the I-shaped support arm 140 and the L-shaped support arm 150, and the positioning pin 120 extends into the inner circle of the splicing glue 10 to be cut. The operator operates the adjusting pin 240 to adjust the position of the sliding groove 130 to adjust the position of the blade holder 200 relative to the splicing glue holder 100, and the blade holder 200 moves to the position of the pre-cutting width with the cutting blade 300. After the adjustment is completed, the operator rotates the adjusting pin 240 to make The long axis end of the elliptical segment 241 presses against the side wall of the adjusting slot 130. At this time, the elliptical segment 241 is interference fit with the adjusting slot 130, and the elliptical segment 241 is limited in the adjusting slot 130. The operator continues to press the blade holder 200 with his hand, and then uses the cutting blade 300 to squeeze and cut the tape surface of the splicing glue 10 to be cut. Then, the splicing glue holder 100 is turned, so that the splicing glue holder 100 rotates along the inner circle of the splicing glue 10 to be cut relative to the splicing glue 10 to be cut. The cutting blade 300 cuts a cutting mark of the required width on the circumference of the tape surface of the splicing glue 10 to be cut. When splicing the formed paper, the tape of the required width can be directly torn off after cutting.

[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
