The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0042] like Figure 1-Figure 13 As shown, a tube cutting device according to an embodiment of the utility model comprises: a cutting knife mechanism 10 and a tube clamping mechanism. The cutting knife mechanism 10 comprises a cutting knife 112. The tube clamping mechanism clamps the tube material to be cut and makes the tube material rotate, and the cutting knife 112 cuts the tube material to form a bead tube.

[0043] It should be noted that in actual application, bead tube embroidery refers to an embroidery technique in which connected beads are fixed on the fabric with an embroidery machine. The connected beads can be divided into bead tubes or beads.

[0044] In the related art, a tube cutting device cuts the elongated tube material to obtain the desired target bead tube. However, the tube cutting device has various problems: 1) it cannot fully automatically cut the bead tube; 2) the lengths of the bead tubes are uneven, which affects the embroidery effect.

[0045] Based on this, in the embodiments of the present application, Figure 4-10As shown, the cutting mechanism 10 includes a cutting knife 112. The pipe clamping mechanism is used to clamp the pipe material to be cut. The pipe clamping mechanism moves relative to the cutting knife 112. The pipe clamping mechanism clamps the pipe material to be cut and causes the pipe material to rotate. The pipe material contacts the cutting knife 112, and then the cutting knife 112 continuously cuts the circumferential contour of the pipe material to form a beaded pipe. The rotating pipe material is cut by the cutting knife 112 to realize automatic cutting of the beaded pipe. At the same time, the rotating pipe material can reduce the size of the entire pipe cutting device, which is conducive to the miniaturization design of the pipe cutting device.

[0046] According to some embodiments of the utility model, the tube clamping mechanism includes a tube clamping seat assembly 20 and a tube rolling assembly 30. The tube clamping seat assembly 20 includes a tube clamping seat body 21, and the tube rolling assembly 30 includes a tube rolling member 31. The tube material is arranged between the tube clamping seat body 21 and the tube rolling member 31, and the tube clamping seat body 21 and the tube rolling member 31 clamp the tube material, and the tube rolling member 31 moves in a direction perpendicular to the axial direction of the tube material to make the tube material rotate.

[0047] In detail, Figure 3 , Figure 5 and Figure 7 As shown, the pipe cutting device includes a support frame 90 and a support frame assembly 50, and the support frame assembly 50 is connected to the support frame 90. The support frame assembly 50 includes a support frame 51, a guide column 52 and a first telescopic mechanism 53 in the Z direction, and the first telescopic mechanism 53 in the Z direction is connected to the support frame 51, and the guide column 52 is connected to the support frame 51, so that the guide column 52 is arranged along the Z direction.

[0048] like Figure 5 and Figure 7 As shown, the cutter mechanism 10 includes a cutter support plate 12, a plurality of cutter assemblies 11 and a guide sleeve 13. The length direction of the cutter support plate 12 is arranged along the X direction, and the plurality of cutter assemblies 11 are arranged along the length direction of the cutter support plate 12. Fig.10 As shown, each cutter assembly 11 includes a cutter connecting member 111 and a cutter 112, and the cutter 112 is disc-shaped. The cutter 112 is rotatably connected to the cutter connecting member 111 so that the cutter 112 can rotate. The movable end of the first telescopic mechanism 53 in the Z direction is connected to the cutter support plate 12 so that the cutter support plate 12 can reciprocate along the Z direction. Among them, the first telescopic mechanism 53 in the Z direction can be a hydraulic mechanism, an electric push rod, a pneumatic push rod, etc., and this embodiment does not limit this. The guide sleeve 13 is connected to the cutter support plate 12, and the guide sleeve 13 cooperates with the guide column 52 to limit the degree of freedom of the cutter support plate 12, that is, the cutter support plate 12 can only move along the Z direction.

[0049] like Figure 7 As shown, the cutter mechanism 10 and the pipe clamping seat assembly 20 are sequentially arranged along the positive direction of the Y direction. Fig.13As shown, the clamp seat assembly 20 includes a clamp seat body 21, and the clamp seat body 21 is provided with a plurality of tube material chambers 211 along the X direction, and a tube material is placed in each tube material chamber 211, and each tube material extends along the Y direction. The tube material chambers 211 correspond to the cutter assembly 11 one by one, that is, each tube material is cut by a cutter 112. The tube material chambers 211 can be roughly in the form of grooves. Fig.13 As shown, the cross section of the groove is semicircular. The cross section of the groove can also be other shapes, which is not limited in this embodiment.

[0050] like Figure 4-Figure 7 As shown, the tube rolling assembly 30 can be located above the tube clamping seat assembly 20, and the tube rolling assembly 30 includes a tube rolling member 31 and an X-direction telescopic mechanism 33, and the movable end of the X-direction telescopic mechanism 33 is connected to the tube rolling member 31 so that the tube rolling member 31 can reciprocate along the X-direction. The X-direction telescopic mechanism 33 can be a hydraulic mechanism, an electric push rod, a pneumatic push rod, etc., which is not limited in this embodiment.

[0051] The tube material is arranged between the tube clamping seat 21 and the tube rolling member 31. The tube material is clamped by the tube clamping seat 21 and the tube rolling member 31. The movable end of the X-direction telescopic mechanism 33 makes the tube rolling member 31 move in a direction (X direction) perpendicular to the axial direction (Y direction) of the tube material, so that the tube material rotates. That is, each tube material can rotate clockwise, and each tube material can also rotate counterclockwise. The rotating tube material is cut with the stationary cutter 112 to realize automatic cutting of the bead tube.

[0052] Optionally, the pipe clamp body 21 is in rolling contact with the pipe material.

[0053] In a specific embodiment, Figure 9-13 As shown, the pipe clamp seat assembly 20 also includes a plurality of rollers 22. A roller mounting groove 212 is also provided on the pipe clamp seat body 21. The roller mounting groove 212 extends along the X direction and is connected to each pipe material chamber 211. The width of the roller mounting groove 212 can be substantially equal to the length of the roller 22. The plurality of rollers 22 are arranged in the roller mounting groove 212 at equal intervals along the X direction so that the rollers 22 are in circumferential contact with the pipe material. For example, Fig.13 As shown, two rollers 22 are arranged corresponding to one pipe material, and the two rollers 22 are in circumferential contact with the pipe material, and the rollers 22 are in rolling contact with the pipe material, thereby achieving rolling contact between the pipe clamping seat 21 and the pipe material. This can greatly reduce the friction resistance between the pipe material and the pipe clamping seat 21, and help the pipe material to rotate freely.

[0054] Optionally, a damping material piece 34 is provided on the tube rolling piece 31, and the damping material piece 34 is in contact with the tube material.

[0055] In a specific embodiment, Fig.10As shown, a damping material piece 34 is provided on the tube-rubbing member 31. A damping material layer is provided on the surface of the tube-rubbing member 31 in contact with the tube material, and the damping material layer can be a rubber layer, a plastic layer, etc. The area of ​​the surface of the tube-rubbing member 31 in contact with the tube material and the damping material layer can be roughly equal, of course, they can also be unequal, as long as the damping material layer can be in contact with each tube material. Through the contact between the damping material layer and the tube material, the friction force of the tube-rubbing member 31 on the tube material can be increased, wherein the friction force drives the tube material to rotate clockwise or counterclockwise. Increasing the friction force helps to drive the tube material to rotate freely clockwise or counterclockwise.

[0056] Optionally, the pipe cutting device further comprises a first auxiliary pipe pressing member 40. The first auxiliary pipe pressing member 40 reciprocates in the vertical direction, and the first auxiliary pipe pressing member 40 is close to the end of the pipe material to be cut.

[0057] In a specific embodiment, Figure 4-Figure 7 As shown, the cutter mechanism 10, the clamp seat assembly 20, and the first auxiliary pipe pressing member 40 are sequentially arranged along the positive direction of the Y direction. The support frame assembly 50 also includes a second telescopic mechanism 54 in the Z direction, and the second telescopic mechanism 54 in the Z direction is connected to the support frame 51. The movable end of the second telescopic mechanism 54 in the Z direction is connected to the first auxiliary pipe pressing member 40, so that the first auxiliary pipe pressing member 40 can reciprocate along the Z direction. The second telescopic mechanism 54 in the Z direction can be a hydraulic mechanism, an electric push rod, a pneumatic push rod, etc., which is not limited in this embodiment.

[0058] Before the tube rolling member 31 drives the tube to rotate clockwise or counterclockwise or starts to rotate, the second telescopic mechanism 54 in the Z direction enables the first auxiliary tube pressing member 40 to firmly press the tube so that the tube can be stably set in the tube chamber 211 of the tube clamping seat body 21, which helps the cutter 112 to cut the tube.

[0059] Furthermore, the tube rolling assembly 30 also includes a guide assembly 32. The guide assembly 32 includes a guide rail 321 and a slider 322 that are slidably matched, one of which is connected to the first auxiliary tube pressing member 40, and the other is connected to the tube rolling member 31. In this way, the first auxiliary tube pressing member 40 and the tube rolling member 31 can reciprocate in the Z direction at the same time. When the first auxiliary tube pressing member 40 presses the tube material, the tube rolling member 31 can reciprocate in the X direction through the guide assembly 32.

[0060] Of course, it is understandable that the tube rolling assembly 30 can be other structures besides the above structure, for example, the tube rolling assembly 30 includes a worm wheel and a plurality of worms, the length of the worm wheel is set along the X direction, the plurality of worms are arranged at equal intervals along the X direction, and each worm is meshed with the worm wheel. The rotation of the worm wheel drives each worm to rotate, and a tube material can be sleeved on each worm, thereby realizing that the tube material can rotate.

[0061] According to some embodiments of the present invention, the pipe cutting device further includes a feeding mechanism 60, and the feeding mechanism 60 transports the pipe material to a preset position.

[0062] In a specific embodiment, Figure 1 and Figure 2 As shown, a bearing plate 80 is further disposed on the support frame 90 , and a plurality of pipe material channels may be disposed on the bearing plate 80 , each of which is communicated with a pipe material chamber 211 of the pipe clamp seat body 21 .

[0063] The pipe cutting device includes a feeding mechanism 60, which feeds the pipe material to a preset position. Figure 2 and Figure 7 As shown, the cutter mechanism 10, the tube clamp seat assembly 20, the first auxiliary tube pressing member 40, and the feeding mechanism 60 are sequentially arranged along the positive direction of the Y direction. The feeding mechanism 60 includes a gear 62, a rack 63, and a push plate 61, and the rack 63 is arranged along the Y direction. The gear 62 is meshed with the rack 63, and the gear 62 is connected to the push plate 61. Through the positive rotation of the gear 62, the push plate 61 is driven to push the uncut end of the tube material, and then the other end of the tube material is cut by the cutter 112, thereby forming a bead tube. Among them, the movement distance of the push plate 61 can control the length of the bead tube, so that the length of the bead tube can be configured according to demand. Through the reverse rotation of the gear 62, the push plate 61 is driven to return to the initial position.

[0064] In practical applications, taking into account the poor straightness of the pipe, it is ensured that the cut end of the pipe can be stably set in the pipe chamber 211 of the pipe clamp seat body 21. When the pipe rotates, there is a risk that the middle part or the other end of the pipe jumps out of the pipe channel, resulting in the cut end of the pipe cannot be cut by the cutter 112.

[0065] Based on this, the pipe cutting device further includes a second auxiliary pipe pressing member 70. Figure 2 and Figure 7 As shown, the cutter mechanism 10, the pipe clamp seat assembly 20, the first auxiliary pipe pressing member 40, the second auxiliary pipe pressing member 70, and the feeding mechanism 60 are sequentially arranged along the positive direction of the Y direction, and the second auxiliary pipe pressing member 70 reciprocates along the vertical direction (Z direction), and the second auxiliary pipe pressing member 70 is away from the cut end of the pipe material. The second auxiliary pipe pressing member 70 can press the middle part of the pipe material. When the second auxiliary pipe pressing member 70 presses the pipe material, the second auxiliary pipe pressing member 70 exerts a moderate force on the pipe material. For example, the second auxiliary pipe pressing member 70 can elastically press the pipe material. In this way, the second auxiliary pipe pressing member 70 can avoid damaging the pipe material, and the second auxiliary pipe pressing member 70 allows the pipe material to be stably arranged in the pipe material channel.

[0066] According to some embodiments of the present invention, the cutter mechanism 10 further includes a first elastic member, which is connected to the cutter 112 so that the cutter 112 can reciprocate in the extension and contraction direction of the first elastic member.

[0067] In a specific embodiment, Fig.11 As shown, the cutter assembly 11 includes a cutter connecting member 111, a cutter 112, a spring 113 and a cutter support seat 114. Among them, the spring 113 is a first elastic member. A spring installation cavity is provided on the cutter support seat 114, and the spring 113 is arranged in the spring installation cavity. One end of the spring 113 is connected to the bottom of the spring installation cavity, and the other end is connected to the cutter connecting member 111. The cutter 112 is rotatably connected to the cutter connecting member 111.

[0068] When the cutter assembly 11 moves downward, approaches and contacts the pipe material, the pipe material is stationary because it is set on the pipe clamping seat assembly 20. The cutter 112 is under the action of the spring 113, as shown in FIG. Fig.11 As shown, it can move up and down. In this way, the cutter 112 and the tube material can be cut flexibly, the cutting impact force of the cutter 112 on the tube material is suppressed, and accidental damage to the tube beads is avoided.

[0069] Similarly, it can be understood that the pipe clamping mechanism includes a pipe clamping seat assembly 20, on which the pipe material is placed, and the pipe clamping seat assembly 20 includes a second elastic member, the telescopic end of the second elastic member abuts against the pipe material, so that when the cutter 112 cuts the pipe material, the pipe material can move away from or close to the cutter 112. The second elastic member can be the same as the first elastic member. The second elastic member allows the pipe material to move downward, and when the cutter 112 cuts the pipe material, the pipe material and the cutter 112 are flexibly cut, and the pipe material can move downward and then move upward, thereby suppressing the cutting impact force of the cutter 112 on the pipe material and avoiding accidental damage to the pipe beads.
