[0002] Jacquard machine is a kind of textile equipment that forms different patterns by controlling the rise and fall of warp threads. It usually consists of a pattern book, a jacquard device and a loom body. The pattern information is recorded on the pattern book. The jacquard device controls the rise and fall of the warp threads according to the information in the pattern book, and interweaves them with the weft threads to form various patterns. The threads are then cut by a heated cutter to complete the weaving process of the fabric. The heated cutter heats the cutting tool to a high temperature through an electric heating element to achieve cleaner and more precise cutting.
[0003] When the cutter is used for too long and becomes worn and aged, or is used improperly or is subjected to an accidental collision, it may break. In some existing technologies, the operator may not be able to discover the breakage of the cutter in time and fail to replace the cutter in time, so that the textile can no longer be cut. However, the textile is always transported on the textile equipment, which will affect the normal working process and even affect the subsequent work process. Therefore, in order to solve the above problems, a heating cutter breakage detection device for a jacquard machine is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figures 1 to 4 As shown, the utility model provides a heating cutter fracture detection device for a jacquard machine, which is arranged on the equipment body 1 of the jacquard machine. The outer wall of the equipment body 1 is fixedly connected to a bracket 10, and the outer wall of the top of the bracket 10 is provided with a detection mechanism 2; the detection mechanism 2 includes a fixed plate 201, the inner wall of the fixed plate 201 is provided with a groove 207, the outer wall of the top of the bracket 10 is fixedly connected to a slide rail 204, the outer wall of the slide rail 204 is slidably connected to a moving block 205, and the inner wall of the fixed plate 201 is elastically connected to the outer wall of the fixed plate 201 through a return spring 202. The first heating module 3, the outer wall of the first heating module 3 is fixedly connected with a rubber pad 203, the top inner wall of the bracket 10 is fixedly connected with a gravity sensor 206, the top outer wall of the fixed plate 201 is fixedly connected with the second heating module 4, the outer walls of the first heating module 3 and the second heating module 4 are fixedly connected with a fixed block 6, the inner wall of the fixed block 6 is slidably connected with two groups of wedge blocks 7, the two groups of wedge blocks 7 are elastically connected by a connecting spring 8, the outer wall of the fixed block 6 is clamped with a cutter body 5, and the outer wall of the cutter body 5 is provided with a through groove 9.
[0023] The above solution is adopted: the device body 1 is the jacquard machine shell, which is the existing technology. The bracket 10 can be fixed to the device body 1 by the existing technology such as bolts. The first heating module 3 and the second heating module 4 on the bracket 10 can heat the cutter body 5, so that the heated cutter body 5 can cut the textile material; when the operator uses the cutter body 5 improperly, when the cutter body 5 is accidentally hit, or when the cutter body 5 is excessively worn, it may cause the cutter body 5 to break. When it breaks, the detection mechanism 2 can sound an alarm, prompting manual replacement of the cutter body 5; the first heating module 3 and the second heating module 4 ... Module 4 is a prior art, and a heating wire is provided inside it. Through its contact with the outer wall of the cutter body 5, heat can be transferred to the cutter body 5 to heat it; the top surface of the gravity sensor 206 in the detection mechanism 2 is flush with the top outer wall surface of the bracket 10. When the first heating module 3 and the moving block 205 move to the top of the gravity sensor 206, the gravity sensor 206 senses its gravity and transmits the signal to the alarm, which can emit a sound to alarm. The alarm is electrically connected to the gravity sensor 206 and can be installed under the bracket 10. It is a prior art, so it is not shown in the figure.
[0024] When the cutter body 5 is mounted on the outer wall of the first heating module 3 and the second heating module 4, the first heating module 3 is not in contact with the gravity sensor 206. Figure 2 As shown, at this time, the return spring 202 is in a stretched state. In this state, when the cutter body 5 breaks, the return spring 202 can move the first heating module 3 to the left due to its own elastic force, and the moving block 205 moves to the left synchronously on the slide rail 204; in the process of the first heating module 3 moving, the rubber pad 203 constantly contacts the inner walls of the multiple groups of grooves 207, resulting in a certain deformation and increasing the friction, thereby slowing down the amplitude of the movement of the first heating module 3 driven by the elastic force of the return spring 202, avoiding the problem that the elastic force is too large and the first heating module 3 moves too fast, colliding with the fixed plate 201 and being damaged; when the moving block 205 moves to the gravity sensor 206, an alarm can be issued, promptly reminding the operator that the cutter body 5 is broken and needs to be replaced, thereby avoiding the problem that the operator cannot understand the situation in time after the cutter body 5 breaks, delaying the time of replacing the cutter body 5, and thus affecting the overall progress of the textile work.
[0025] like Figures 1 to 4As shown, the fixed plate 201 is fixedly connected to the top outer wall of the bracket 10, and the first heating module 3 is fixedly connected to the top outer wall of the moving block 205; one end of the return spring 202 is fixedly connected to the outer wall of the first heating module 3, and the other end of the return spring 202 is fixedly connected to the outer wall of the fixed plate 201; the outer wall of the rubber pad 203 contacts the inner wall of the groove 207, and the fixed block 6 contacts the inner wall of the through groove 9; the two ends of the connecting spring 8 are respectively fixedly connected to the outer walls of the two groups of wedge blocks 7, and the wedge blocks 7 contact the outer wall of the cutter body 5; the outer walls of the first heating module 3 and the second heating module 4 are both in contact with the outer wall of the cutter body 5, and the fixed block 6 is cylindrical; the outer wall of the slide rail 204 is fixedly connected to the outer wall of the fixed plate 201, and two groups of wedge blocks 7 are provided.
[0026] The above scheme is adopted: when the cutter body 5 is not installed, the return spring 202 moves the first heating module 3 and the moving block 205 to the far left due to its own elastic force, and corresponds to the position of the gravity sensor 206. At this time, the gravity sensor 206 is in the closed state and no alarm is issued; when installing the cutter body 5, the right side slot 9 of the cutter body 5 can be first aligned with the position of the fixed block 6 on the second heating module 4, and the cutter body 5 is moved toward the second heating module 4. The fixed block 6 is inserted into the slot 9, and the arc surface of the two groups of wedge blocks 7 is squeezed by the inner wall of the slot 9 and moved to the inner wall of the fixed block 6. The connecting spring 8 is forced to shrink. When the cutter body 5 moves to the point where its outer wall is in contact with the outer wall of the second heating module 4, the inner wall of the slot 9 is out of contact with the outer wall of the wedge block 7, and pops out to both sides under the elastic force of the connecting spring 8. The straight surface of the wedge block 7 contacts the outer wall of the cutter body 5 to limit it, so that the right side of the cutter body 5 can be fixed.
[0027] Then the first heating module 3 can be pulled to the right, the return spring 202 is stretched, and the moving block 205 moves above the slide rail 204. When the first heating module 3 moves to the position of the fixed block 6 corresponding to the through slot 9 on the left side of the cutter body 5, the above steps can be repeated to connect the through slot 9 with the fixed block 6, and the left side of the cutter body 5 is fixed by the wedge block 7. The cutter body 5 is made of an alloy composite material and has a certain softness and flexibility. It can be bent to a certain extent without breaking during the installation process; when the two groups of through slots 9 of the cutter body 5 are connected with the fixed block 6, the installation of the cutter body 5 is completed, so that the cutter body 5 does not need to be fixed by multiple thick rotating bolts, which is more convenient and quick; after the installation of the cutter body 5 is completed, the gravity sensor 206 can be started to issue an alarm in time when the cutter body 5 breaks.
[0028] The working principle and use process of this utility model:
[0029] When the cutter body 5 is not installed, the return spring 202 moves the first heating module 3 and the moving block 205 to the far left due to its own elastic force, and corresponds to the position of the gravity sensor 206. At this time, the gravity sensor 206 is in the off state and no alarm is issued; when installing the cutter body 5, the right side through slot 9 of the cutter body 5 is first aligned with the position of the fixed block 6 on the second heating module 4, and the fixed block 6 is plugged into the through slot 9. The arc surfaces of the two groups of wedge blocks 7 are squeezed by the inner wall of the through slot 9 and move into the inner wall of the fixed block 6, and the connecting spring 8 is forced to shrink; when the cutter body 5 moves to the point where its outer wall fits the outer wall of the second heating module 4, the wedge blocks 7 pop out to both sides under the elastic force of the connecting spring 8, and the straight surface of the wedge blocks 7 contacts the outer wall of the cutter body 5 to limit it, thereby fixing the right side of the cutter body 5.
[0030] Then pull the first heating module 3 to the right, the return spring 202 is stretched, and the moving block 205 moves above the slide rail 204. When the first heating module 3 moves to the position of the fixed block 6 corresponding to the through slot 9 on the left side of the cutter body 5, repeat the above steps to connect the through slot 9 with the fixed block 6, and fix the left side of the cutter body 5 through the wedge block 7, so that the installation of the cutter body 5 can be completed quickly and easily without the need to rotate the bolts multiple times for installation operations, which is more convenient. After the installation is completed, the gravity sensor 206 can be turned on to issue an alarm when the cutter body 5 breaks.
[0031] The first heating module 3 and the second heating module 4 are provided with heating wires, which contact the outer wall of the cutter body 5 to transfer heat to the cutter body 5 and heat it. The heated cutter body 5 can cut the material. At this time, the first heating module 3 is not in contact with the gravity sensor 206, and the return spring 202 is in a stretched state. If the cutter body 5 is accidentally hit or the cutter body 5 is excessively worn due to improper use by the operator, the cutter body 5 will break. When it breaks, the return spring 202 can move the first heating module 3 to the left due to its own elastic force, and the moving block 205 moves to the left synchronously on the slide rail 204. When the moving block 205 moves to the gravity sensor 206, the gravity sensor 206 senses its gravity and transmits a signal to the alarm. The alarm sounds, which can promptly remind the operator that the cutter body 5 needs to be replaced. This avoids the problem that the operator cannot understand the situation in time after the cutter body 5 breaks, delays the replacement of the cutter body 5, and thus affects the overall progress of the textile work.
[0032] The operator can then turn off the gravity sensor 206 to disable the audible alarm, press the two sets of wedges 7, remove the broken cutter body 5 from the first heating module 3 and the second heating module 4, and install a new cutter body 5. The textile cutting operation can then be continued. The efficiency of textile cutting will not be affected due to failure to discover the problem in time, and the installation and removal of the cutter body 5 is also relatively convenient, thereby improving work efficiency.
