[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] The following is combined Figures 1-5 This invention describes a tooling for changing the tipping paper cutter.

[0037] like Figure 1 and Figure 2 As shown, this utility model provides a tooling for changing the blade of a tipping paper cutter, including: a tooling body 1, with a limiting groove 11 and an abutment part 12 on one side of the tooling body 1. The abutment part 12 is used to abut against the blade holder of the tipping paper cutter (not shown in the figure); the opposite side walls of the limiting groove 11 are respectively used to abut against the two sides of the blade 2 of the tipping paper cutter, and the bottom of the limiting groove 11 is used to abut against the cutting edge of the blade 2.

[0038] In this embodiment, it is understood that the tooling body 1 is used to limit the position of the blade 2 to be installed on the knife holder. Specifically, by providing an abutment part 12 and a limiting groove 11 on one side of the tooling body 1, when installing the blade 2, the abutment part 12 can be abutted against the corresponding position of the knife holder to position the tooling body 1, thereby positioning the limiting groove 11. The limiting groove 11 is used to set the blade 2. The groove walls on opposite sides of the limiting groove 11 abut against the sides of the blade 2 to limit the position of the blade 2 along the width direction of the limiting groove 11. The bottom of the limiting groove 11 abuts against the cutting edge of the blade 2 to position the cutting edge of the blade 2, thereby limiting the length of the blade 2 extending out of the knife holder, so that the extension of the blade 2 can meet the cutting requirements of the cork paper cutter, and can maintain the position of the blade 2 on the knife holder during installation, making it less likely for the blade 2 to shift.

[0039] This utility model of a tipping paper cutter changing fixture features an abutment part 12 on the fixture body 1, which abuts against the blade holder for positioning the fixture body 1 on the blade holder. Simultaneously, a limiting groove 11 is provided on the fixture body 1 to limit the position of the blade 2 during installation. The two sides of the limiting groove 11 abut against the two sides of the blade 2, preventing displacement of the blade 2 along the width direction of the limiting groove 11. The bottom of the limiting groove 11 abuts against the blade edge, restricting the blade edge position and ensuring that the extension of the blade 2 meets the cutting requirements of the tipping paper cutter. This utility model of a tipping paper cutter changing fixture can maintain the extension of the blade 2 within a set range during installation and maintain the position of the blade 2 until installation is complete, resulting in higher installation efficiency and less risk of displacement.

[0040] It is understandable that the tooling body 1 can be a one-piece molded part or a combined mechanism formed by assembling multiple parts.

[0041] Specifically, in some embodiments, such as Figure 1 As shown, the tooling body 1 includes a base 13, a pressing member 14, and a limiting component 15. Both the pressing member 14 and the limiting component 15 are mounted on the base 13, which is positioned opposite to the pressing member 14. At least a portion of the limiting component 15 is located between the base 13 and the pressing member 14. The base 13 has an abutment portion 12. Opposite sides of the base 13 and the pressing member 14 respectively form opposite side walls of a limiting groove 11. The end face of the portion of the limiting component 15 located between the base 13 and the pressing member 14 forms the bottom of the limiting groove 11.

[0042] In this embodiment, the base 13 is provided with an abutment portion 12. When installing the blade 2, the base 13 abuts against the blade holder through the abutment portion 12 to position the entire tooling body 1. The pressing member 14 is arranged opposite to the base 13 to form opposite side walls of the limiting groove 11. The pressing member 14 can press the blade 2 to be installed onto the base 13. At the same time, a part of the limiting component 15 is located between the base 13 and the pressing member 14. The end face of this part of the limiting component 15 can form the bottom of the limiting groove 11 to abut against the blade edge of the blade 2, thereby positioning the blade edge of the blade 2 so that the elongation of the blade 2 meets the cutting requirements of the cork paper cutter. The structure is simple, convenient and practical.

[0043] In some embodiments, such as Figure 1 As shown, the limiting component 15 includes a limiting member 151, a portion of which is located between the base 13 and the pressure member 14. The limiting member 151 can slide along the depth direction of the limiting groove 11 to adjust the depth of the limiting groove 11.

[0044] In this embodiment, a portion of the limiting member 151 is disposed between the base 13 and the pressing member 14. The end face of this portion of the limiting member 151 can form the bottom of the limiting groove 11 to abut against the cutting edge of the blade 2. Simultaneously, the limiting member 151 can slide along the depth direction of the limiting groove 11 to adjust the position of the bottom of the limiting groove 11, thereby adjusting the depth of the limiting groove 11. By adjusting the depth of the limiting groove 11, before installing the blade 2, the limiting member 151 can be slid away from the groove opening to allow the blade 2 to be inserted into the limiting groove 11, and then slid closer to the groove opening to push the blade 2 to a designated position, ensuring that the elongation of the blade 2 meets the cutting requirements. Furthermore, when the required elongation of the blade 2 changes, the position of the limiting member 151 can be adjusted to meet the positioning requirements of different blade elongation amounts.

[0045] In some embodiments, such as Figure 1 and Figure 3 As shown, the limiting member 151 includes a first part 1511 and a second part 1512 connected together. The first part 1511 is disposed between the base 13 and the pressure member 14. The second part 1512 protrudes from the first part 1511 toward one side of the base 13. The second part 1512 is used to abut against the side of the base 13 away from the groove opening of the limiting groove 11.

[0046] In this embodiment, the first portion 1511 of the limiting member 151 is located between the base 13 and the pressing member 14. The end of the first portion 1511 is used to form the bottom of the limiting groove 11 so as to abut against the cutting edge of the blade 2, thereby positioning the cutting edge of the blade 2. At the same time, it can be understood that a part of the structure of the first portion 1511 extends to the edge or outer side of the base 13 away from the opening of the limiting groove 11. This part of the structure is provided with a second portion 1512, which protrudes towards the base 13 so that when the first portion 1511 slides towards the opening of the limiting groove 11, the second portion 1512 can abut against the side of the base 13 away from the opening of the limiting groove 11, so as to limit the first portion 1511. The structure is simple and the effect is good.

[0047] Specifically, in some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the tipping paper cutter changing fixture also includes a first fastener (not shown in the figure). The base 13 has a first fixing hole 131. The limiting member 151 has a first oblong hole 1513 extending along the depth direction of the limiting groove 11, corresponding to the position of the first fixing hole 131. The pressing member 14 has a second fixing hole 141 corresponding to the position of the first fixing hole 131. The first fastener is used to sequentially pass through the second fixing hole 141, the first oblong hole 1513, and the first fixing hole 131 to fix the base 13, the pressing member 14, and the limiting member 151.

[0048] In this embodiment, by providing a first fixing hole 131, a first waist-shaped hole 1513, and a second fixing hole 141 with corresponding positions on the base 13, the limiting member 151, and the pressing member 14 respectively, after the blade 2 is positioned, the first fastener can be passed through the second fixing hole 141, the first waist-shaped hole 1513, and the first fixing hole 131 in sequence to lock and fix the base 13, the pressing member 14, and the limiting member 151, thereby preventing the base 13, the pressing member 14, and the limiting member 151 from sliding relative to each other after the blade 2 is positioned, thus preventing the blade 2 from shifting. Meanwhile, the first waist-shaped hole 1513 extends along the depth direction of the limiting groove 11 so that the positioning position of the blade can be adjusted according to the elongation requirement. When the position of the first waist-shaped hole 1513 relative to the first fixing hole 131 and the second fixing hole 141 changes, the first fastener can still pass through the first fixing hole 131, the first waist-shaped hole 1513 and the second fixing hole 141 to lock and fix the base 13, the pressure member 14 and the limiting member 151.

[0049] Understandably, before positioning the blade 2, the first fastener can be passed through the second fixing hole 141 and the first waist-shaped hole 1513. In this state, the limiting member 151 can move relative to the pressing member 14 and the base 13 to adjust the positioning position of the blade. After positioning the blade 2, the first fastener can be passed through the first fixing hole 131 to press the pressing member 14 against the limiting member 151, thereby locking and fixing the base 13, the pressing member 14, and the limiting member 151.

[0050] It is understood that there can be multiple first fixing holes 131, and multiple first fixing holes 131 are spaced apart along the length direction of the limiting groove 11 on the base 13. Correspondingly, there are also multiple first fasteners, first waist-shaped holes 1513 and second fixing holes 141, and they are arranged one-to-one with the first fixing holes 131.

[0051] In some embodiments, such as Figure 1 and Figure 5As shown, the limiting component 15 also includes a pressing member 152, which is slidably disposed on the base 13. The pressing member 152 abuts against the side of the limiting member 151 opposite to the limiting groove 11. The pressing member 152 is used to drive the limiting member 151 to slide towards the opening of the limiting groove 11.

[0052] In this embodiment, a sliding pressing member 152 is provided on the base 13. The pressing member 152 abuts against the limiting member 151. The maintenance personnel can press the pressing member 152 to make the pressing member 152 slide on the base 13 to push the limiting member 151 to slide in the direction of the groove, so that the limiting member 151 can abut against the cutting edge of the blade 2, so as to push the blade 2 to the designated position and make the elongation of the blade 2 meet the cutting requirements.

[0053] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the tipping paper cutter changing fixture also includes a second fastener (not shown in the figure). A third fixing hole 132 is provided on the base 13. A second oblong hole 1521 extending along the depth direction of the limiting groove 11 is provided on the pressing member 152 at the position corresponding to the third fixing hole 132. The second fastener is used to pass through the second oblong hole 1521 and the third fixing hole 132 to fix the pressing member 152 to the base 13.

[0054] In this embodiment, by providing corresponding third fixing holes 132 and second oblong holes 1521 on the base 13 and pressing member 152 respectively, after the blade 2 is positioned, the second fastener can be passed through the second oblong hole 1521 and the third fixing hole 132 in sequence to press and fix the pressing member 152, preventing relative sliding between the base 13 and the pressing member 152 after the blade 2 is positioned. At the same time, the pressing member 152 abuts against the limiting member 151, which can limit the limiting member 151. The second oblong hole 1521 extends along the depth direction of the limiting groove 11 so that the positioning position of the blade can be adjusted according to the elongation requirement. When the relative position of the second oblong hole 1521 relative to the third fixing hole 132 changes, the second fastener can still pass through the second oblong hole 1521 and the third fixing hole 132 to lock and fix the base 13 and the pressing member 152.

[0055] Understandably, before positioning the blade 2, the second fastener can be passed through the third fixing hole 132 and the second oblong hole 1521 and left unlocked. In this state, the pressing member 152 can move relative to the base 13 to push the limiting member 151 to adjust the positioning position of the blade. After positioning the blade 2, the second fastener can be adjusted to the locked state, pressing the pressing member 152 against the base 13, locking and fixing the base 13 and the pressing member 14. At the same time, the pressing member 14 can also abut against and limit the limiting member 151.

[0056] It is understandable that there can be multiple third fixing holes 132, and multiple third fixing holes 132 are spaced apart along the length direction of the limiting groove 11 on the base 13. Correspondingly, there are also multiple second fasteners and second waist-shaped holes 1521, which are set one-to-one with the third fixing holes 132.

[0057] In some embodiments, such as Figure 1 and Figure 5 As shown, the pressing member 152 includes a third part 1522 and a fourth part 1523 connected together. The third part 1522 is slidably disposed on the base 13. The fourth part 1523 protrudes from the third part 1522 toward the limiting member 151 and is used to abut against the side of the limiting member 151 away from the limiting groove 11.

[0058] In this embodiment, the third part 1522 of the pressing member 152 is slidably connected to the base 13 so that the pressing member 152 can slide along the base 13 to drive the limiting member 151 to slide. The third part 1522 is provided with a fourth part 1523, which protrudes towards the limiting member 151 so that when the third part 1522 slides towards the opening of the limiting groove 11, the fourth part 1523 can abut against the side of the limiting member 151 away from the limiting groove 11, so as to push the limiting member 151 to move towards the opening of the limiting groove 11 and abut against the cutting edge of the blade 2, so as to position the cutting edge of the blade 2 and make the elongation of the blade 2 meet the cutting requirements.

[0059] In some embodiments, such as Figure 1 and Figure 2 As shown, the base 13 has a stepped surface 133 on the side opposite to the limiting member 151. The stepped surface 133 includes a first plane and a second plane that are offset from each other, as well as a transition surface connecting the first plane and the second plane. The height of the first plane is higher than the height of the second plane. The third part 1522 is disposed on the second plane, and the side of the third part 1522 opposite to the second plane is flush with the first plane.

[0060] In this embodiment, a stepped surface 133 is provided on one side of the base 13. The stepped surface 133 has a first plane with a higher height and a second plane with a lower height, as well as a transition surface between the two. The second plane and the transition surface form a groove-shaped structure relative to the first plane. The third part 1522 of the pressing member 152 is disposed in the groove-shaped structure. The thickness of the third part 1522 is the same as the height difference between the first plane and the second plane, so that the side of the third part 1522 facing away from the second plane can be flush with the first plane, making the whole structure more compact.

[0061] In some embodiments, when the abutting part 12 abuts against the tool holder, one side of the groove wall of the limiting groove 11 is flush with the plane of the tool holder used to install the blade 2.

[0062] In this embodiment, by reasonably setting the relative positions of the limiting groove 11 and the abutment part 12, when the abutment part 12 abuts against the tool holder and the tool body 1 is positioned on the tool holder, one side of the groove wall of the limiting groove 11 is flush with the plane on the tool holder for mounting the blade 2. This allows the blade 2 to be tightly attached to the plane on the tool holder for mounting the blade 2 after it is inserted into the limiting groove 11, so that maintenance personnel can press and fix the blade 2 on the tool holder through the corresponding pressing structure.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
