In the related art, when the line number pipe is cut by a cutter of the line number printer, the line number pipe is prone to displacement relative to the cutter, which causes the length of the cut line number pipe to be inconsistent, thereby affecting the cutting effect of the line number pipe.

[0075] The line number printer, also known as a line number printer, can print characters on a line number tube such as a sleeve, a heat shrink tube, etc., and is used for wiring identification of electrical control, power distribution and the like.
[0076] After the character printing is completed, the line number tube needs to be cut. In the related art, when the line number tube is cut by the cutter of the line number printer, the line number tube is prone to displacement relative to the cutter, resulting in inconsistent length of the line number tube after cutting, and affecting the cutting effect of the line number tube.
[0077] To solve the above technical problems, the application provides a pipe cutting device and a line number printer.
[0078] Please refer to Figure 1 The application provides a line number printer 1, which comprises a pipe cutting device 10. The pipe cutting device 10 is used to cut the line number pipe 2 according to a preset length after the line number printer 1 completes character printing on the line number pipe 2, so as to obtain a line number pipe 2 with a required length.
[0079] As shown in the figure, Figure 2 The pipe cutting device 10 can comprise a cutter 100 and an elastic positioning member 200. The cutter 100 has a blade 110. The cutter 100 can move along a first direction X. The elastic positioning member 200 can move along the first direction X. Along the first direction X, the elastic positioning member 200 partially protrudes from the blade 110, and is used to fix the line number pipe 2 before the blade 110 contacts the line number pipe 2.
[0080] The cutter 100 is a cutting tool. The blade 110 of the cutter 100 is usually thin and sharp. The cutter 100 can have a blade shape. The cutter 100 can be made of various materials, such as stainless steel, carbon steel, ceramic, etc. The blade 110 of the cutter 100 can have a straight line shape or an arc shape, etc.
[0081] The elastic positioning member 200 is used to fix the line number pipe 2. The elastic positioning member 200 has a certain elasticity. When the elastic positioning member 200 presses against the line number pipe 2, the elastic positioning member 200 will be deformed and apply a force to the line number pipe 2. When the elastic positioning member 200 is separated from the line number pipe 2, the elastic positioning member 200 can return to the original shape. The elastic positioning member 200 can be a torsion spring, a spring sheet, etc. When the elastic positioning member 200 is a torsion spring, the torsion arm of the torsion spring can press against the line number pipe 2 and apply a force to the line number pipe 2, so as to fix the line number pipe 2.
[0082] The cutter 100 and the elastic positioning member 200 can move along the first direction X towards the line number pipe 2 under the action of an external force. Along the first direction X, the elastic positioning member 200 at least partially protrudes from the blade 110, or in other words, along the moving direction of the cutter 100, the elastic positioning member 200 can be partially or entirely located in front of the blade 110. Since the elastic positioning member 200 is partially or entirely located in front of the blade 110, the elastic positioning member 200 can fix the line number pipe 2 in advance before the blade 110 contacts the line number pipe 2, i.e., before the line number pipe 2 is cut, so as to avoid the line number pipe 2 moving relative to the blade 110 when the line number pipe 2 is cut, and the phenomenon that the lengths of the cut line number pipes 2 are inconsistent.
[0083] The scheme provided in the application can realize that the cutting tool 100 and the elastic positioning piece 200 can move along the first direction X when the marking number pipe 2 is cut, and since the elastic positioning piece 200 partially extends from the blade 110 of the cutting tool 100, the elastic positioning piece 200 can first press against the marking number pipe 2 to fix the marking number pipe 2 before the blade of the cutting tool cuts the marking number pipe 2, and then the blade 110 of the cutting tool contacts and cuts the marking number pipe 2. The application can fix the marking number pipe 2 in advance through the elastic positioning piece 200, so that the marking number pipe 2 can be prevented from being displaced relative to the blade 110 of the cutting tool 100 when the marking number pipe 2 is cut, the length of the marking number pipe 2 cut is ensured to be consistent, and the cutting effect of the marking number pipe 2 is effectively improved. It can be seen that the application can solve the problem that the length of the marking number pipe 2 cut is inconsistent.
[0084] Referring to Figure 2 and Figure 3 In some embodiments, the blade 110 extends along a second direction Y; the second direction Y intersects the first direction X; the elastic positioning piece 200 includes a pressing section 210, the pressing section 210 partially extends from the blade 110 and extends along the second direction Y, and the distance d1 between the pressing section 210 and the blade 110 along the first direction X is greater than or equal to 3 mm and less than or equal to 8 mm.
[0085] In order to realize overall cutting of the marking number pipe 2 and make the cutting surface of the marking number pipe 2 in an expected neat and smooth state, the blade 110 of the cutting tool 100 can extend in a straight line as a whole, for example, can extend along the second direction Y as shown in Figure 2 The angle between the second direction Y and the first direction X can be an acute angle, an obtuse angle or a right angle.
[0086] The pressing section 210 of the elastic positioning piece 200 partially extends from the blade 110, so that the marking number pipe 2 can be fixed in advance before the blade 110 contacts the marking number pipe 2. The pressing section 210 extends along the second direction Y, so that the marking number pipe 2 can be overall pressed and fixed. Referring to Figure 3 The distance d1 between the pressing section 210 and the blade 110 along the first direction X is greater than or equal to 3 mm and less than or equal to 8 mm, for example, can be 3 mm, 3.2 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, etc. In this way, the blade 110 can cut the marking number pipe 2 in time after the marking number pipe 2 is fixed by the pressing section 210. If the distance between the pressing section 210 and the blade 110 along the first direction X is less than 3 mm, the blade 110 may cut the marking number pipe 2 before the marking number pipe 2 is completely fixed by the pressing section 210, which affects the cutting effect. If the distance between the pressing section 210 and the blade 110 along the first direction X is greater than 8 mm, the cutting interval time is large, which reduces the working efficiency of the marking number printer 1.
[0087] Please continue to see Figure 3 In some embodiments, the length d2 of the compression section 210 along the second direction Y is greater than or equal to 10 mm and less than or equal to 20 mm, for example, 10 mm, 11 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, etc. In this way, the compression section 210 can achieve good pressing and fixing effects on the cable tube 2. It should be noted that if the length of the compression section 210 along the second direction Y is less than 10 mm, the compression section 210 cannot achieve complete pressing on most specifications of the cable tube 2, and the pressing effect is poor. If the length of the compression section 210 along the second direction Y is greater than 20 mm, when the cable tube 2 is pressed, the contact point between the cable tube 2 and the compression section 210 is not in the middle of the compression section 210, which is easy to cause the compression section 210 to tilt, affecting the pressing and fixing effects on the cable tube 2.
[0088] See Figure 1 , Figures 5 to 7 In some embodiments, the cutter 100 and the elastic positioning member 200 have a wire passing channel 400 extending along the thickness direction of the cutter 100 on one side along the first direction X; the compression section 210 has a compression position and an initial position; when in the compression position, the compression section 210 is located within the wire passing channel 400; when in the initial position, the compression section 210 is located outside the wire passing channel 400.
[0089] It can be understood that the wire passing channel 400 allows the path of the cable tube 2 to pass through, and the cable tube 2 is located within the wire passing channel 400 and can move along the extension direction of the wire passing channel 400. When the cable number printer 1 prints characters on the cable tube 2, the cable tube 2 can move freely in the wire passing channel 400, at this time, the cutting device 10 does not cut the cable tube 2, and the compression section 210 is in the initial position, and the compression section 210 in this position is located outside the wire passing channel 400, avoiding blocking the free movement of the cable tube 2 and affecting the printing of characters on the cable tube 2. When the character printing is completed, the cable tube 2 needs to be cut. At this time, the cutter 100 and the elastic positioning member 200 move along the first direction X towards the cable tube 2, and the compression section 210 moves to the compression position, and the compression section 210 in this position is located within the wire passing channel 400, which can press and fix the cable tube 2, thereby achieving good cutting effect.
[0090] From the above, it can be seen that the cutter 100 and the elastic positioning member 200 can be a split structure or a whole structure. The cutter 100 and the elastic positioning member 200 in the split structure are two separate structural members, and the cutter 100 and the elastic positioning member 200 in the whole structure are connected as one whole structural member.
[0091] For the cutter 100 and the elastic positioning member 200 as a whole, in some embodiments, referring to Figures 5 to 8 , the elastic positioning member 200 can further include a connecting segment 220, one end of the connecting segment 220 being connected with one end of the pressing segment 210; the cutting device 10 can further include a base 300, the base 300 including a base body 310, the base body 310 being connected with the cutter 100 and the other end of the connecting segment 220; the connecting segment 220 extending towards the base 300; the base 300 being movable along the first direction X. In other words, the cutter 100 and the elastic positioning member 200 can be connected as a whole through the base body 310 of the base 300, specifically, the cutter 100 can be fixed on the base body 310 through clamping, screwing, bonding or the like, and the pressing segment 210 of the cutter 100 can be connected with the base body 310 through the connecting segment 220. The cutter 100 and the elastic positioning member 200 as a whole have a more compact structure, which is convenient for control and use. When cutting the wire number pipe 2, only an external force needs to be applied to the base 300, so that the base 300 drives the cutter 100 and the elastic positioning member 200 to move along the first direction X together.
[0092] In some embodiments, referring to Figure 7 , Figures 9 to 11 , the wire routing channel 400 can include a first segment 410 and a second segment 420, the first segment 410 and the second segment 420 being located upstream and downstream of the cutter 100 and the elastic positioning member 200 respectively; the elastic positioning member 200 can further include a cantilever segment 230, the cantilever segment 230 extending towards the base 300; one end of the cantilever segment 230 being connected with the other end of the pressing segment 210, the cantilever segment 230 being lower than the bottom wall 411 of the first segment 410.
[0093] Wherein, the wire number pipe 2 moves from the upstream of the cutter 100 and the elastic positioning member 200 to the downstream of the cutter 100 and the elastic positioning member 200. It can be understood that the connecting segment 220 and the cantilever segment 230 are respectively located at two ends of the pressing segment 210, which can make the pressing segment 210 extend along the second direction Y. Since the wire number pipe 2 located in the middle of the first segment 410 and the second segment 420 is in a suspended state, the wire number pipe 2 will vertically droop under the action of gravity, and the cantilever segment 230 extends towards the base 300 and is overall inclined, in order to avoid that the bottom of the wire number pipe 2 is incompletely pressed by the inclined cantilever segment 230, affecting the fixing effect of the wire number pipe 2, the cantilever segment 230 is set to be lower than the bottom wall 411 of the first segment 410, that is, lower than the bottom wall 411 of the upstream wire routing channel 400, in this way, the pressing segment 210 can completely press the wire number pipe 2, and a better pressing effect can be obtained.
[0094] Referring to Figures 5 to 8In some embodiments, the base body 310 has a gap (not shown in the figure) and is provided with a limiting portion 311; the cantilever segment 230 is arranged in the gap; the other end of the cantilever segment 230 extends out of the gap and the end of the other end of the cantilever segment 230 is provided with a bent portion 231; when the pressing segment 210 is in the initial position, the bent portion 231 abuts against the limiting portion 311 to prevent the cantilever segment 230 from being pulled out of the gap.
[0095] It should be noted that the base body 310 can have various structural forms. In one implementation manner, as shown in Figure 1 the base body 310 can be a spliced part connected by clamping of a base plate 312 and a cover plate 313. In this structural form, the gap on the base body 310 is a gap between the base plate 312 and the cover plate 313. One of the base plate 312 and the cover plate 313 can be provided with the limiting portion 311, which can be an outward protruding structure as shown in Figure 1 or an inward recessed structure. In another implementation manner, the base body 310 can be a block-shaped part, for example, a regular cuboid block or an irregular polygonal block. In this structural form, the gap on the base body 310 can be a through hole, and the limiting portion 311 can be an outward protruding structure or an inward recessed structure near the through hole of the base body 310. It should be noted that the designer can flexibly set the size of the gap or the through hole according to actual needs, and the embodiments of the present application do not make specific limitations in this regard.
[0096] In order to prevent the cantilever segment 230 arranged in the gap from being pulled out of the gap, the embodiments of the present application further provide the bent portion 231 at the end of the cantilever segment 230 extending out of the gap. When the pressing segment 210 is in the initial position, the bent portion 231 can abut against the limiting portion 311 to block the cantilever segment 230 from being pulled out of the gap. The bending direction of the bent portion 231 intersects with the extension direction of the cantilever segment 230, and the bending direction of the bent portion 231 can be flexibly selected on the premise of playing a blocking role, and the embodiments of the present application do not make specific limitations in this regard.
[0097] Referring to Figure 4In some embodiments, along the thickness direction Z of the cutter piece 100, the distance d3 between the elastic positioning piece 200 and the blade 110 is greater than 0 mm and less than or equal to 4 mm. For example, it can be 0.5 mm, 1 mm, 1.4 mm, 1.6 mm, 2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.2 mm, 3.5 mm, 4 mm, etc. In this way, when the line number tube 2 is cut, the part of the line number tube 2 that is close to the blade 110 can be reliably fixed by the elastic positioning piece 200, so that a better cutting effect can be obtained. It should be noted that if the distance between the two is 0 mm, that is, the elastic positioning piece 200 is not misaligned with the cutter piece 100, then when the line number tube 2 is cut, the elastic positioning piece 200 and the cutter piece 100 will interfere, affecting the cutting effect of the line number tube 2. If the distance between the two is greater than 4 mm, since the elastic positioning piece 200 only fixes the part of the line number tube 2 that is pressed, the part of the line number tube 2 that is actually cut and is far from the pressing part of the elastic positioning piece 200 will still move. In this case, the cutter piece 100 is still prone to cutter displacement during cutting, affecting the cutting effect of the line number tube 2.
[0098] Referring to Figure 5 In some embodiments, the base 300 can further include a cover 320 connected with the base body 310, and the cover 320 covers the top of the cutter piece 100. It can be understood that the cover 320 located at the top of the cutter piece 100 can shield the blade 110 of the cutter piece 100, so as to isolate the human body (such as fingers) from the blade 110 when the user uses or maintains the line number printer 1, preventing the human body (such as fingers) from being accidentally touched by the blade 110 and being cut. The cover 320 and the base body 310 can be a split structure, and the cover 320 can be connected with the base body 310 by clamping, screwing, bonding, etc. In addition, the cover 320 and the base body 310 can also be an integrated structure, and the two can be processed by injection molding, additive manufacturing, etc.
[0099] Referring to Figure 6 and Figure 7 In some embodiments, the cover 320 includes a body part 321 and an extension part 322. The body part 321 is connected with the base body 310; the extension part 322 is connected with the body part 321, and the extension part 322 extends along the first direction X, and along the first direction X, the distance d4 between the end of the extension part 322 and the blade 110 is greater than or equal to 5 mm and less than or equal to 15 mm, for example, it can be 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc.
[0100] In consideration of the fact that the user may approach the blade 110 from the side of the cutter 100 when using or maintaining the thread printing machine 1, the body part 321 of the cover 320 is further provided with an extension part 322 extending in the first direction X. When a human body approaches the blade 110 from the side of the cutter 100, the extension part 322 can block the human body, and better prevent the human body from being cut. In order to effectively block the human body, the distance between the end of the extension part 322 and the blade 110 should not be too small. If the distance is less than 5 mm, even if the extension part 322 blocks the human body, the human body will still be cut due to the inertia caused by touching the blade 110. In addition, considering the space limitation, material cost and the like of the thread printing machine 1, the length of the extension part 322 should not be too long, and the distance between the end of the extension part 322 and the blade 110 should be less than or equal to 15 mm.
[0101] Referring to Figure 8 In some embodiments, the size d5 of the cover 320 along the thickness direction Z of the cutter 100 is greater than or equal to 2 mm and less than or equal to 15 mm, for example, 2 mm, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc.
[0102] In consideration of the fact that the user may approach the blade 110 from the front and back of the cutter 100 when using or maintaining the thread printing machine 1, the thickness of the cover 320 should not be too small. In this way, when a human body approaches the blade 110 from the front and back of the cutter 100, the cover 320 can block the human body, and better prevent the human body from being cut. In addition, considering the space limitation, material cost and the like of the thread printing machine 1, the width of the cover 320 should not be too wide, and the size of the cover 320 along the thickness direction Z of the cutter 100 should be less than or equal to 15 mm.
[0103] Referring to Figure 1 and Figure 9 In some embodiments, the pipe cutting device 10 can further include an anvil 500 and a driving member (not shown in the figure). The anvil 500 has a switchable full cutting surface and a half cutting surface (not shown in the figure); the anvil 500 is arranged on one side of the cutter 100 and the elastic positioning member 200; the orthographic projection of the cutter 100 and the elastic positioning member 200 on the anvil 500 is located on the full cutting surface or the half cutting surface; and the driving member is used to drive the cutter 100 and the elastic positioning member 200 to move relative to the anvil 500.
[0104] In the full cutting surface of the anvil 500 is a flat surface, and the normal projection of the cutter 100 and the elastic positioning member 200 on the anvil 500 is located on the full cutting surface, so that the cutting of the line number pipe 2 can be completely cut, and the line number pipe 2 is completely cut off, that is, the line number pipe 2 is completely separated. The half cutting surface of the anvil 500 is only partially flat, so that when the normal projection of the cutter 100 and the elastic positioning member 200 on the anvil 500 is located on the full cutting surface, the cutting of the line number pipe 2 can only be partially cut, and the line number pipe 2 is not completely cut off.
[0105] When the cutter 100 and the elastic positioning member 200 are in a split structure, the number of driving members can be two, and the two driving members can drive the cutter 100 and the elastic positioning member 200 to move relative to the anvil 500 along the first direction X respectively. When the cutter 100 and the elastic positioning member 200 are in a whole structure, the number of driving members is only one, and one driving member can simultaneously drive the cutter 100 and the elastic positioning member 200 to move relative to the anvil 500 along the first direction X.
[0106] The normal projection of the cutter 100 and the elastic positioning member 200 on the anvil 500 in the embodiments of the present application is located on the full cutting surface or the half cutting surface, so that when the anvil 500 is switched between the full cutting surface and the half cutting surface by rotating or the like, the cutter 100 and the elastic positioning member 200 can be located on the full cutting surface or the half cutting surface at the same time, avoiding that one of the cutter 100 and the elastic positioning member 200 is located on the full cutting surface and the other is located on the half cutting surface, which causes the line number pipe 2 to be cut obliquely, so that a better cutting effect can be obtained.
