Description

Technical Field

[0001] This invention relates to the field of infrared positioning device technology, and in particular to an infrared positioning device for fabric cutting. Background Technology

[0002] The kosher is a hat worn by Jews every day. However, in the process of making a kosher, the fabric needs to be cut. The common cutting method is to use a guide rail to drive an infrared positioner to the corresponding position, and then project an infrared line onto the worktable through the infrared positioner. Then, the fabric is unfolded to the position of the infrared line, and the cutter on the worktable can cut the fabric at the position of the infrared line to obtain the corresponding length of fabric, so that the fabric can be used for subsequent processing.

[0003] In existing fabric cutting technology, infrared positioners on electric guide rails are typically powered by power cords. The connection method mainly involves connecting the cable plug on the infrared positioner to the female connector on the power cord. To meet the functional requirements of the electric guide rail driving the infrared positioner to move laterally at different positions on the worktable and emit infrared rays, the power cord is often quite long. However, although existing hangers are equipped with hooks for hanging the power cord, during the fabric cutting process, the electric guide rail frequently drives the infrared positioner to move. This causes the cable plug on the infrared positioner and the female connector on the power cord to be subjected to continuous swinging forces. Over time, this swinging will cause the plug and connector to loosen, thus preventing the infrared positioner from working properly and requiring maintenance, thereby affecting the production schedule. Furthermore, when the power cord swings back and forth, it will rub against the hooks. Long-term friction can cause the power cord to break, resulting in leakage, or even causing the infrared positioner to burn out.

[0004] To address the aforementioned issues, this application proposes an infrared positioning device for fabric cutting. Summary of the Invention

[0005] This invention proposes an infrared positioning device for fabric cutting, which solves the problem in related technologies where the plug and connector of the infrared positioner become loose, thus preventing the infrared positioner from working properly.

[0006] The present invention provides an infrared positioning device for fabric cutting, comprising an infrared positioner, an electric guide rail, a hanging rod, and an eccentric assembly;

[0007] The electric guide rail is installed at the bottom of the boom, the infrared positioner is mounted on the drive end of the electric guide rail, the eccentric component is installed on the boom and its vertical position is adjustable; a loading cylinder is installed on the eccentric component, and a spiral female end piece is provided inside the loading cylinder; a plug is connected to the infrared positioner via a cable, and the plug is used to plug into and cooperate with the spiral female end piece.

[0008] As the electric guide rail drives the infrared positioner to move laterally to its edge, the cable pulls the spiral female end piece to extend out of the loading cylinder and drives the eccentric component to deflect to adapt to the position of the infrared positioner.

[0009] As a further optimization of the present invention, the eccentric assembly includes a sleeve block, a first eccentric disk, and a second eccentric disk. The sleeve block is sleeved on the lifting rod, and a bolt for fixing its position is threaded onto the sleeve block. The edge of the first eccentric disk is rotatably connected relative to the sleeve block. A first sliding groove is formed on the first eccentric disk, and a first elastic element is installed in the first sliding groove. The edge of the second eccentric disk is rotatably connected relative to the first elastic element. A second sliding groove is formed on the second eccentric disk, and a second elastic element is installed in the second sliding groove. The loading cylinder is detachably installed on the second elastic element.

[0010] As a further optimization of the present invention, the first elastic element includes a first spring and a first slider. The first slider is installed in the first groove through the first spring and slides in a sliding fit with it. The edge of the second eccentric disk is rotatably connected to the first slider.

[0011] As a further optimization of the present invention, the second elastic element includes a second spring and a second slider. The second slider is installed in the second groove through the second spring and slides in a sliding fit with it. The second slider has a threaded channel, and one end of the loading cylinder is threadedly connected to the threaded channel.

[0012] As a further optimization of the present invention, the spiral female end component includes a spiral body, a female end, a main power line and a sealing head. The sealing head is inserted into the end of the loading cylinder, the main power line is connected to the outside of the sealing head, the spiral body is connected to the main power line and disposed inside the loading cylinder, the female end is connected to the end of the spiral body, a sliding member is installed on the second slider, the female end is mounted on the sliding member, and the plug is inserted into the female end.

[0013] As a further optimization of the present invention, the sliding component includes a loading disk and a limiting guide rod. The second slider has two insertion channels, and the limiting guide rod is slidably inserted into each of the two insertion channels. The loading disk is installed at one end of the two limiting guide rods. A sliding opening is provided in the insertion channel. The other end of the limiting guide rod is fixed with a protrusion that slides with the sliding opening. The loading disk has an insertion port, and the female end is inserted into the insertion port. The loading disk is provided with a locking component for locking the female end.

[0014] As a further optimization of the present invention, the locking element is a bolt head, and the loading disc is threaded with a bolt head that fixes the female end.

[0015] As a further optimization of the present invention, the number of the lifting rods is several, arranged at intervals along the electric guide rail, and the sleeve block is located on the middle lifting rod.

[0016] The above-described technical solution of the present invention has the following beneficial technical effects:

[0017] 1. The infrared positioner on the electric guide rail of this invention is normally located in the middle position. When in use, the plug at the end of its cable is inserted into the spiral female end piece. When cutting the fabric, the electric guide rail drives the infrared positioner to move slightly laterally. The cable drives the spiral female end piece to extend slightly, the sliding part moves outward, and the eccentric component deflects slightly. After the infrared positioner is in place, it projects infrared light for cutting reference. After cutting, the infrared positioner resets, the spiral female end piece retracts into the loading cylinder by elasticity, and the sliding part resets. This design, through the cooperation of the eccentric component, the loading cylinder and the spiral female end piece, ensures that the cable plug and the spiral female end piece are stably connected when the infrared positioner moves slightly, avoiding loosening due to swinging and cable damage.

[0018] 2. When cutting non-standard fabrics, the infrared positioner needs to be moved to its edge area by an electric guide rail. During this process, the cable on the infrared positioner pulls the spiral female end piece inside the loading cylinder. The spiral female end piece extends outward significantly, and the sliding part connected to it moves outward. Under the action of the sliding part, the eccentric component is driven to deflect significantly. The above design allows the infrared positioner to move smoothly to the edge area of ​​the electric guide rail when cutting non-standard fabrics, thereby expanding the applicability of the cutting equipment, meeting the cutting needs of fabrics of different sizes, improving the flexibility of the equipment, and enhancing its adaptability in actual production.

[0019] 3. To better adapt to the distance the infrared positioner moves to the edge of the electric guide rail, when the infrared positioner moves to the edge of the electric guide rail, the cable pulls the spiral female end piece and drives the sliding part to move outward. At this time, the second elastic element on the second eccentric disk can move downward elastically, and the second eccentric disk can deflect on the first elastic element of the first eccentric disk. The first elastic element can also move downward elastically, and the first eccentric disk can deflect on the sleeve block. The above design forms a multi-stage elastic deflection action, which can better adapt to the distance the infrared positioner moves to the edge of the electric guide rail, thereby adaptively adjusting the extension length and force state of the spiral female end piece, and avoiding excessive stretching or bending of the cable.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0029] like Figures 1-7 As shown, the present invention proposes an infrared positioning device for fabric cutting, comprising an infrared positioner 1, an electric guide rail 2, a hanging rod 3, and an eccentric component 4.

[0030] The electric guide rail 2 is installed at the bottom of the boom 3, the infrared positioner 1 is mounted on the drive end of the electric guide rail 2, the eccentric component 4 is installed on the boom 3 and its vertical position is adjustable; a loading cylinder 5 is installed on the eccentric component 4, and a spiral female end piece 6 is provided inside the loading cylinder 5; a plug 102 is connected to the infrared positioner 1 through a cable 101, and the plug 102 is used to plug into and cooperate with the spiral female end piece 6.

[0031] As the electric guide rail 2 drives the infrared positioner 1 to move laterally to its edge, the cable 101 pulls the spiral female end piece 6 to extend out of the loading cylinder 5 and drives the eccentric assembly 4 to deflect to adapt to the position of the infrared positioner 1.

[0032] When in use, connect the plug 102 of the cable 101 on the infrared positioner 1 to the spiral female terminal 6 to establish a power supply path.

[0033] When the electric guide rail 2 drives the infrared positioner 1 to move laterally to the edge, the cable 101 will generate a lateral tension, pulling the spiral female end piece 6 to extend out of the loading cylinder 5, and at the same time causing the eccentric component 4 to deflect. The key to this design is that the elastic extension and contraction characteristics of the spiral female end piece 6 absorb the movement allowance of the cable 101, and then the deflection of the eccentric component 4 adaptively adjusts the force direction of the cable 101, avoiding excessive pulling or bending of the cable 101, ensuring that the connection between the plug 102 and the spiral female end piece 6 remains stable throughout the entire stroke of the infrared positioner 1, and will not become loose due to frequent movement. At the same time, it avoids damage caused by friction between the cable 101 and other components, reduces the risk of leakage, equipment burnout, etc., and ensures that the infrared positioner 1 can stably project infrared rays. Then the infrared positioner 1 projects infrared rays to the worktable position at its bottom, and then the fabric is unfolded, and the fabric at the infrared position can be cut.

[0034] In this embodiment, the eccentric assembly 4 includes a sleeve block 41, a first eccentric disk 42, and a second eccentric disk 43. The sleeve block 41 is sleeved on the lifting rod 3, and a bolt for fixing its position is threaded onto the sleeve block 41. The edge of the first eccentric disk 42 is rotatably connected relative to the sleeve block 41. A first sliding groove is provided on the first eccentric disk 42, and a first elastic element 44 is installed in the first sliding groove. The edge of the second eccentric disk 43 is rotatably connected relative to the first elastic element 44. A second sliding groove is provided on the second eccentric disk 43, and a second elastic element 45 is installed in the second sliding groove. The loading cylinder 5 is detachably installed on the second elastic element 45.

[0035] The structure of the eccentric component 4 mainly realizes multi-level elastic deflection, achieving flexible adaptation to the movement of cable 101, as detailed below:

[0036] When the infrared locator 1 moves the traction cable 101, the force is transmitted to the loading cylinder 5 through the spiral female end piece 6. The loading cylinder 5 drives the second elastic element 45 to move downward, and the second eccentric disk 43 deflects relative to the first elastic element 44. At the same time, the first elastic element 44 is subjected to force and moves downward, and drives the first eccentric disk 42 to deflect relative to the sleeve block 41, forming a multi-level deflection and elastic buffer linkage, thereby converting the rigid tension of the cable 101 into flexible deflection and elastic deformation, avoiding excessive local force that could cause the plug 102 to loosen or the cable 101 to break. At the same time, it makes the movement of the infrared locator 1 smoother and adaptable to different distance movement requirements.

[0037] The specific requirements for adapting to different distance travel are as follows:

[0038] When cutting conventional fabrics, the electric guide rail 2 drives the infrared positioner 1 to move slightly in the middle. The distance that the second elastic element 45 and the first elastic element 44 move downward elastically is small. The deflection amplitude of the second eccentric disk 43 relative to the first elastic element 44 and the deflection amplitude of the first eccentric disk 42 relative to the sleeve block 41 are both small. When cutting non-conventional fabrics, the distance that the second elastic element 45 and the first elastic element 44 move downward elastically is larger. The deflection amplitude of the second eccentric disk 43 relative to the first elastic element 44 and the deflection amplitude of the first eccentric disk 42 relative to the sleeve block 41 are both larger.

[0039] When the height of the eccentric component 4 on the rod 3 needs to be adjusted, simply loosen the bolts on the sleeve block 41 to allow the sleeve block 41 to slide on the rod 3. After the sleeve block 41 moves to the corresponding position, its position can be locked by the bolts to fix the eccentric component 4 as a whole, thereby adapting to different installation and working requirements.

[0040] In this embodiment, the first elastic element 44 includes a first spring 441 and a first slider 442. The first slider 442, which is slidably engaged with the first spring 441, is installed in the first groove. The edge of the second eccentric disk 43 is rotatably connected to the first slider 442. The second elastic element 45 includes a second spring 451 and a second slider 452. The second slider 452, which is slidably engaged with the second spring 451, is installed in the second groove. A threaded channel is provided in the second slider 452. One end of the loading cylinder 5 is threadedly connected to the threaded channel.

[0041] When the loading cylinder 5 is pulled by the cable 101, it will drive the second slider 452 to move down in the second groove, stretching the second spring 451. The elastic force of the second spring 451 forms a buffer. At the same time, the second eccentric disk 43 rotates eccentrically relative to the first slider 442 and drives the first slider 442 to move down. The second spring 451 connected to it is stretched, forming a buffer effect. Under the force, the first eccentric disk 42 deflects relative to the sleeve block 41, forming a multi-level deflection and elastic buffer linkage, so that the rigid tension of the cable 101 is transformed into flexible deflection and elastic deformation, avoiding excessive local force that could cause the plug 102 to loosen or the cable 101 to break.

[0042] It should be noted that the threaded channel inside the second slider 452 is connected to the threaded connection at one end of the loading cylinder 5, which allows the loading cylinder 5 to be installed and disassembled by rotation, and at the same time facilitates the subsequent inspection and replacement of the spiral female end piece 6 inside the loading cylinder 5.

[0043] In this embodiment, the spiral female end piece 6 includes a spiral body 61, a female end 62, a main power line 63, and a sealing head 64. The sealing head 64 is inserted into the end of the loading cylinder 5, and the main power line 63 is connected to the outside of the sealing head 64. The spiral body 61 is connected to the main power line 63 and is disposed inside the loading cylinder 5. The female end 62 is connected to the end of the spiral body 61. A sliding member 7 is installed on the second slider 452, and the female end 62 is mounted on the sliding member 7. The plug 102 is inserted into and engaged with the female end 62.

[0044] The sealing head 64 is inserted into the end of the loading cylinder 5, which serves to seal and protect the spiral body 61 inside the loading cylinder 5, preventing dust and debris from entering and affecting its expansion or conductivity. The main power line 63 provides power input to the entire device.

[0045] In use, plug 102 on cable 101 is connected to female end 62. When infrared positioner 1 moves to pull cable 101, plug 102 drives female end 62 to move. Sliding part 7 slides synchronously with female end 62. The extension and retraction characteristics of spiral body 61 can adapt to the moving distance of infrared positioner 1, avoiding excessive pulling of cable 101.

[0046] It should be noted that the present invention improves the traditional long power cord that hangs on the hook into a spiral female end piece 6 loaded into the loading cylinder 5. Through its elastic extension and contraction, the problem of wear caused by swinging on the hook is solved.

[0047] In this embodiment, the sliding member 7 includes a loading disk 71 and a limiting guide rod 73. The second slider 452 has two insertion channels, and the limiting guide rod 73 is slidably inserted into each of the two insertion channels. The loading disk 71 is installed at one end of the two limiting guide rods 73. A sliding opening is provided in the insertion channel. The other end of the limiting guide rod 73 is fixed with a protrusion that slides with the sliding opening. The loading disk 71 has an insertion port, and the female end 62 is inserted into the insertion port. The loading disk 71 is provided with a locking member for locking the female end 62. The locking member is a bolt head 72. The loading disk 71 is threaded with a bolt head 72 for fixing the female end 62.

[0048] During installation, the female end 62 is inserted into the socket in the loading tray 71, and then it can be tightened by the bolt head 72 on the loading tray 71. When the female end 62 is pulled, it will drive the loading tray 71 to move. The limit guide rod 73 slides along the insertion channel, and the protrusion slides synchronously along the sliding mouth to guide the movement of the female end 62, preventing the female end 62 from shaking or deviating during the movement, ensuring that the plug 102 and the female end 62 always remain in a docked state, preventing poor contact from causing unstable power supply to the infrared positioner 1, and further adapting to the movement requirements of the infrared positioner 1.

[0049] It should be noted that when disassembling the female end piece 6 of the spiral wire, simply loosen the bolt head 72 on the loading plate 71, push the female end piece 62 out of the slot opened in the loading plate 71, and then remove the sealing head 64 from the end of the loading cylinder 5. This will allow the spiral wire body 61 and the female end piece 62 to be taken out of the loading cylinder 5, thus completing the overall disassembly of the female end piece 6 of the spiral wire, which is convenient for subsequent replacement and maintenance.

[0050] In this embodiment, there are several lifting rods 3, which are arranged at intervals along the electric guide rail 2, and the sleeve block 41 is located on the middle lifting rod 3;

[0051] The sleeve 41 is located on the middle hanger 3, so that the installation position of the eccentric component 4 is in the middle area of ​​the electric guide rail 2. In this way, the infrared positioner 1 is normally in the middle of the electric guide rail 2. The eccentric component 4 in the middle position can make the initial distance between the spiral female end piece 6 and the infrared positioner 1 the shortest, so that the cable 101 is not excessively stretched in the initial state. At the same time, when the infrared positioner 1 moves to the two sides, the eccentric component 4 in the middle position can provide a more uniform deflection angle and extension allowance, avoiding uneven force on the cable 101 when moving on one side, optimizing the force state of the eccentric component 4, making the cooperation between the cable 101 and the spiral female end piece 6 more reasonable, and further ensuring the connection stability of the infrared positioner 1 during movement.

[0052] The specific working principle of this invention is as follows:

[0053] Connect the plug 102 at the end of the cable 101 on the infrared positioner 1 to the female end 62 to complete the power supply connection of the entire device. At this time, the infrared positioner 1 is normally located in the middle of the electric guide rail 2, and the spiral body 61 is retracted into the loading cylinder 5.

[0054] During the cutting of conventional fabric, the infrared positioner 1 is driven by the electric guide rail 2 to move slightly laterally in the central area. During this process, the cable 101 of the infrared positioner 1 drives the female end 62 to move outward. The female end 62 drives the two limiting guide rods 73 to slide outward along the insertion channel of the second slider 452 through the loading plate 71. At the same time, the female end 62 pulls the spiral body 61 to extend slightly outward from inside the loading cylinder 5. The spiral structure of the spiral body 61 provides elastic support to prevent the cable 101 from being pulled excessively. As the sliding member 7 moves, the force is transmitted to the second slider 452, causing the second spring 451 to undergo slight elastic deformation in the second groove. The second eccentric plate 43 deflects slightly relative to the first slider 442, and the first slider 442 deflects slightly in the first groove. Sliding, the first spring 441 undergoes a slight elastic deformation, and the first eccentric disk 42 deflects slightly relative to the sleeve block 41, forming a multi-level flexible buffer deflection structure. When the infrared positioner 1 moves to the preset cutting position, the electric guide rail 2 stops running. The infrared positioner 1 projects infrared rays onto the workbench below. The worker unfolds the fabric to the infrared position and cuts the infrared irradiated area using a cutter. After cutting, the electric guide rail 2 drives the infrared positioner 1 back to the middle position. The spiral body 61 retracts into the loading cylinder 5 under its own elastic action. The first spring 441 and the second spring 451 respectively push the first slider 442 and the second slider 452 to reset. The deflection angle of the first eccentric disk 42 and the second eccentric disk 43 is restored, and the sliding part 7 returns to the initial position.

[0055] When cutting non-standard fabrics, the infrared positioner 1 needs to move to the edge area of ​​the electric guide rail 2. The electric guide rail 2 drives the infrared positioner 1 to move significantly towards the edge, and the cable 101 is subjected to a large traction force, causing the female end 62 and the sliding part 7 to move significantly outward. The spiral body 61 extends significantly from inside the loading cylinder 5, and its spiral structure is fully stretched to adapt to the moving distance. At this time, the second slider 452 slides significantly in the second slide groove, the second spring 451 is stretched significantly, the second eccentric disk 43 deflects significantly relative to the first slider 442, the first slider 442 slides significantly in the first slide groove, the first spring 441 is fully elastically deformed, and the first eccentric disk 42 deflects significantly relative to the sleeve block 41. The infrared positioner 1 deflects significantly, forming a multi-stage elastic deflection action that adaptively absorbs the traction force of the cable 101, preventing the cable 101 from being overstretched or bent. When the infrared positioner 1 reaches the preset position at the edge of the electric guide rail 2, it stops moving and projects infrared rays. The operator cuts the fabric according to the infrared positioning. Similarly, after the cutting is completed, the electric guide rail 2 drives the infrared positioner 1 to reset, the spiral body 61 elastically retracts, and each component resets in sequence, restoring the device to its initial state. In this stage, through multi-stage elastic deflection and the significant extension and retraction of the spiral body 61, the infrared positioner 1 is adapted to move throughout its entire stroke, expanding the applicability of the device and meeting the cutting and positioning needs of fabrics of different sizes.

[0056] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
