Description

Technical Field

[0001] This invention relates to the field of cutting machine technology, specifically to a synchronous belt fixed-length cutting machine that prevents deviation. Background Technology

[0002] Synchronous belts are flexible transmission components widely used in mechanical transmission. During production, they need to be cut to a set length. Currently, the fixed-length cutting of synchronous belts is mostly done manually or with semi-automatic equipment, which has the following drawbacks: 1. Existing cutting equipment lacks effective dust removal, leveling, and static electricity removal devices during synchronous belt conveying. Dust easily adheres to the surface of the synchronous belt, static electricity is generated, or wrinkles appear, causing the synchronous belt to deviate during conveying, affecting cutting accuracy, and even causing unqualified cutting lengths, resulting in material waste.

[0003] 2. The height of the guide rollers in the existing equipment is mostly fixed. When changing the belt feeding roller for continuous feeding, the synchronous belt discharge end needs to go up and down multiple times to pass through each set of guide rollers. This can easily cause the adsorption device to detach from the synchronous belt discharge end, which not only affects production efficiency but also requires manual re-threading, increasing labor intensity.

[0004] 3. Existing cutting equipment lacks an effective offset detection device before cutting, and cannot monitor the position of the timing belt in real time. When the timing belt deviates, it cannot be detected and corrected in time, resulting in the timing belt being skewed after cutting and a high scrap rate.

[0005] 4. Existing equipment typically uses independent drive sources to control each functional module (such as dust removal, detection, and blowing), which is complex in structure, high in cost, and lacks linkage and coordination between modules, resulting in a low degree of automation. It still requires manual operation and cannot meet the needs of efficient and automated production. Summary of the Invention

[0023] Example 2

[0024] Please refer to Figure 1 and Figure 5 As shown, the auxiliary mechanism 2 includes a first fixed frame 201 fixedly connected to the front side of the body 1. A first lead screw 202 is rotatably connected inside the first fixed frame 201. A movable plate 205 is threadedly connected to the outer wall of the first lead screw 202.

A second cylinder 208 is fixedly connected to the lifting plate 207. A vacuum suction plate 209 is fixedly installed on the output end of the second cylinder 208.

[0025] Those skilled in the art will understand that by controlling the output end of the first stepper motor 204 to drive the first lead screw 202 to rotate, the moving plate 205 moves horizontally back and forth along the outer wall of the first guide rod 203, thereby driving the vacuum suction plate 209 to move horizontally back and forth; and by controlling the output end of the first cylinder 206 to extend or retract, the lifting plate 207 moves upward or downward, thereby driving the vacuum suction plate 209 to move up and down; in addition, by controlling the output end of the second cylinder 208 to extend or retract, the vacuum suction plate 209 moves backward or forward.

[0026] Example 3

[0027] Please refer to Figure 1 , Figure 3 and Figure 4 As shown, the adjustment mechanism 3 includes a second fixed frame 301 fixedly connected to the rear side of the top of the machine body 1.

[0028] Those skilled in the art will understand that by driving the second lead screw 302 to rotate through the output end of the second stepper motor 304, the lifting block 305 moves up and down along the outer wall of the second guide rod 303. Therefore, by controlling the rotation of the output ends of the three sets of second stepper motors 304, the height of the three sets of second guide rollers 105 can be adjusted.

[0029] Example 4

[0030] Please refer to Figure 7 As shown, the moving mechanism 4 includes a third lead screw 402 and a third guide rod 403. A third fixed frame 401 is fixedly installed on the top rear side of the machine body 1. The third lead screw 402 is rotatably connected to the third fixed frame 401, and the third guide rod 403 is fixedly connected to the third fixed frame 401.

A third cylinder 406 is fixedly installed on the top of the moving block 405, and the lifting frame 106 is fixedly connected to the output end of the third cylinder 406.

[0031] Those skilled in the art will understand that by controlling the output end of the third stepper motor 404 to drive the third lead screw 402 to rotate, the moving block 405 moves back and forth along the outer wall of the third guide rod 403, thereby driving the lifting frame 106, the multi-functional mechanism 5, the drive mechanism 6 and the offset detection mechanism 7 to move back and forth as a whole; in addition, by controlling the output end of the third cylinder 406 to extend or retract, the lifting frame 106, the multi-functional mechanism 5, the drive mechanism 6 and the offset detection mechanism 7 are driven to move upward or downward as a whole, thus changing their overall height.

[0032] Example 5

[0033] Please refer to Figure 9 and Figure 12 As shown, the drive mechanism 6 includes a fourth fixed frame 601 and a movable part 605. The fourth fixed frame 601 is welded to the top of the lifting frame 106. A fourth lead screw 602 is rotatably connected inside the fourth fixed frame 601. The movable part 605 is threadedly connected to the fourth lead screw 602. A fourth guide rod 603 is also fixedly connected inside the fourth fixed frame 601. The movable part 605 is slidably connected to the fourth guide rod 603. A fourth stepper motor 604 for driving the fourth lead screw 602 to rotate is provided on the outer wall of the fourth fixed frame 601. An insertion hole 606 is provided on the outer wall of one end of the movable part 605. A pressing plate 607 is welded to the bottom of the other end of the movable part 605. A fourth cylinder 608 is installed on the top of the movable part 605. The output end of the fourth cylinder 608 is fixedly connected to the first rack 609.

[0034] Those skilled in the art will understand that by controlling the output end of the fourth stepper motor 604 to drive the fourth lead screw 602 to rotate, the movable part 605 moves horizontally back and forth along the outer wall of the fourth guide rod 603, thereby causing the pressing plate 607, the fourth cylinder 608 and the first rack 609 to move horizontally back and forth as a whole; in addition, by controlling the output end of the fourth cylinder 608 to extend or retract, the first rack 609 is pushed backward or moved forward.

[0035] Example 6

[0036] Please refer to Figure 6 , Figure 8 and Figure 11As shown, the multifunctional mechanism 5 includes a swing nozzle 501 and an ion wind snake air pump 504. The swing nozzle 501 is provided with two sets, both of which are rotatably mounted on the lifting frame 106. The top of each set of swing nozzles 501 is rotatably connected to a rotating arm 503. The other end of the rotating arm 503 is rotatably connected to a connecting block 502. The ion wind snake air pump 504 is located on the back of the machine body 1. The output end of the ion wind snake air pump 504 is connected to both sets of swing nozzles 501 through a connecting pipe 505. The top of the outer side of the connecting block 502 is provided with a plug 506 and an electromagnet 507. The lifting frame 106 is provided with a U-shaped part 107.

[0037] Those skilled in the art will understand that, in Embodiment 5, we described that the movable part 605 can move to the right, and the socket 606 on the movable part 605 also moves to the right, so that the plug 506 on the connecting block 502 is inserted into the socket 606, realizing an electrical connection. When the electromagnet 507 is energized, the movable part 605, being made of ferrous material, is attracted together by the electromagnet 507. Thus, the movable part 605 and the connecting block 502 are connected together and move to the right together, enabling the two sets of rotating arms 503 to rotate, driving the two... The set of oscillating nozzles 501 rotate in a direction away from each other. In addition, when the movable part 605 is driven to move to the left again, the connecting block 502 connected together also moves to the left. The two sets of oscillating nozzles 501 then move in a direction closer to each other. When the connecting block 502 moves to the left, it touches the U-shaped part 107 on the lifting frame 106. The U-shaped part 107 blocks the connecting block 502 from moving to the left, while the movable part 605 continues to move to the left, thus pulling the plug 506 and the socket 606 apart and cutting off the power. The electromagnet 507 then stops working. In summary, within the motion range where the electromagnet 507 is not energized, the two sets of oscillating nozzles 501 can continuously oscillate along the upper surface of the synchronous belt, removing dust from the upper surface of the synchronous belt and also smoothing the synchronous belt to prevent it from shifting due to wrinkles. In addition, in this oscillating state, when the ion wind snake air pump 504 is activated, the bottom of the oscillating nozzles 501 is evenly provided with air holes, and the compressed airflow blows ions onto the surface of the synchronous belt, which can effectively remove static electricity from the surface of the synchronous belt. The ion wind snake air pump 504 used in this embodiment is existing technology. The air pump only provides the air source, and the core is the ion generator. The ion generator produces a large number of positive and negative ions. The air pump compresses the airflow and blows the ions onto the surface of the workpiece with static electricity. Opposite charges neutralize each other, quickly eliminate static electricity, and at the same time blow away dust.

[0038] Example 7

[0039] Please refer to Figure 13As shown, the blower mechanism 8 includes a support plate 801 fixedly installed on the rear side of the top of the body 1. Two sets of telescopic rods 802 are fixedly connected to the left side of the support plate 801. The telescopic ends of the telescopic rods 802 are fixedly connected to the moving parts 803. A spring 804 is sleeved on the outside of the telescopic rods 802. A second rack 805 is fixedly connected to the bottom of the moving parts 803. A second rotating shaft 806 is rotatably connected to the top of the body 1. A second gear 807 and a third bevel gear 808 are fixedly connected to both ends of the second rotating shaft 806, respectively. The second gear 807 and the second rack 805 mesh.

[0040] Please refer to Figure 11 As shown, a blower 812 is installed on the top of the body 1. A sixth bevel gear 813 is fixedly installed at the bottom of the fan shaft of the blower 812. A third rotating shaft 809 is also rotatably connected to the top of the body 1. A fourth bevel gear 810 that meshes with the third bevel gear 808 is fixedly connected to one end of the third rotating shaft 809. A fifth bevel gear 811 that meshes with the sixth bevel gear 813 is fixedly installed at the other end of the third rotating shaft 809.

[0041] Those skilled in the art will understand that, similarly, as described in Embodiment 5, the movable part 605 can move to the right, and the pressing plate 607 connected to it also moves to the right. The pressing plate 607 presses the movable part 803 to the right, causing the second rack 805 to also move to the right. At this time, both the telescopic rod 802 and the spring 804 are in a contracted state. The rightward movement of the second rack 805 drives the second gear 807 meshing with it to rotate, causing the second rotating shaft 806 and the third bevel gear 808 to rotate, which in turn drives the third rotating shaft 809, the fifth bevel gear 811, and the fourth bevel gear 810 to rotate as a whole. The rotation of the fifth bevel gear 811 drives the sixth bevel gear 813 to rotate, thus driving the fan in the blower 812 to rotate and blow off the dust on the lower surface of the synchronous belt. Conversely, when the movable part 605 moves to the left, it no longer presses the movable part 803, and the spring 804 returns to its deformation, thus driving the movable part 803 to the reset state.

[0042] In other words, the movable part 605 reciprocates within the range between the chamfered part 107 and the right end of the fourth fixed frame 601, which can synchronously drive the multi-functional mechanism 5 and the blower mechanism 8 to work.

[0043] Example 8

[0044] Please refer to Figure 10As shown, the offset detection mechanism 7 includes a connecting frame 701, a display panel 705, and a movable block 707. The connecting frame 701 is welded to the left side of the lifting frame 106. Two sets of threaded rods 702 are rotatably connected inside the connecting frame 701. The threads at both ends of the threaded rods 702 have opposite directions of rotation. The display panel 705 is provided with two sets of threads respectively connected to the outer walls of the upper threaded rod 702. A camera 706 is provided at the bottom of the display panel 705, and the movable block 707 is also provided with two sets of threads respectively connected to the outer walls of the lower threaded rod 702. At both ends, a light source spotlight 708 is installed on the top of the movable block 707. A fixing rod 703 is also welded inside the connecting frame 701. The movable block 707 and the display panel 705 are slidably connected to the fixing rod 703. A first rotating shaft 709 is rotatably connected to the outer wall of the connecting frame 701. A first bevel gear 704 is fixedly installed on the outer ends of the two sets of threaded rods 702. A second bevel gear 710 that meshes with the first bevel gear 704 is fixedly connected to both ends of the first rotating shaft 709. A first gear 711 is fixedly installed on the outer wall of the first rotating shaft 709.

[0045] Those skilled in the art will understand that, in Embodiment 5, we described that the movable part 605 can move to the left. When the movable part 605 reciprocates within the range between the chamfered part 107 and the left end of the fourth fixed frame 601, it simultaneously drives the output end of the fourth cylinder 608 to retract, pushing the first rack 609 to the rear. The first rack 609 meshes with the first gear 711, driving the first gear 711 to reciprocate. Through the transmission of the first rotating shaft 709 and the two sets of second bevel gears 710, the two sets of threaded rods 702 are driven to rotate synchronously, adjusting the distance between the two sets of display panels 705, and also adjusting the overall distance between the two sets of movable blocks 707 and the light source spotlight 708. Based on the principles described above, the two sets of light source spotlights 708 are driven to correspond to the front and rear positions of the synchronous belt, respectively. The positions of the two sets of display panels 705 also correspond to the positions of the two sets of light source spotlights 708. The light source spotlights 708 emit point beams of light. At this time, the synchronous belt does not block the emitted laser. The camera 306 on the display panel 705 takes pictures and records the light spots mapped on the display panel 705. At this time, the light spots are the "deepest". If the light spots on the display panel 705 disappear during the synchronous belt's transport, it indicates that the synchronous belt has shifted position. For example, if the light spots disappear on the rear display panel 705, the synchronous belt has shifted to the rear, indicating that there is light blocking.

[0046] Example 9

[0047] Please refer to Figure 1As shown, the cutting assembly includes a cutting table 108 located on the right side of the machine body 1. A first hydraulic rod 109 is located on the rear side of the cutting table 108. A pressure roller 110 is located at the output end of the first hydraulic rod 109. Second hydraulic rods 111 are installed on both the front and rear sides of the cutting table 108. The output ends of the two sets of second hydraulic rods 111 are fixedly connected to the same set of mounting plates 112. A cutter is located at the bottom of the mounting plate 112.

[0048] Those skilled in the art will understand that by intermittently releasing synchronous belts of the same length onto the cutting table 108, and by driving the output ends of the two sets of second hydraulic rods 111 to retract, the cutter is driven to move downward, thus achieving fixed-length cutting of the synchronous belt.

[0049] The working principle of this device is as follows: S1. Initially, in order not to affect the subsequent winding of the synchronous belt, the moving mechanism 4 drives the lifting frame 106, the multi-functional mechanism 5, the driving mechanism 6 and the offset detection mechanism 7 to be located on the top rear side of the machine body 1. The two sets of first guide rollers 104 are at the same height and are located at height B1. The leftmost second guide roller 105 is located at height B2 under the action of the adjusting mechanism 3. The other two sets of second guide rollers 105 also move to height B1. S2. The robotic arm 101 is a multi-functional adsorption robotic arm. It adsorbs the external tape-feeding roller 103 to be cut and clamps it at the output end of the motor 102. Under the action of the auxiliary mechanism 2, the vacuum suction plate 209 is driven to be located at the discharge end of the tape-feeding roller 103. The robotic arm 101 releases the discharge end of the tape-feeding roller 103, and the discharge end of the tape-feeding roller 103 falls on the vacuum suction plate 209 for adsorption. Under the action of the output end of the first step motor 204, the vacuum suction plate 209 drives the adsorbed discharge end of the tape-feeding roller 103 to move to the right, and pulls the synchronous belt horizontally along the height position B1 and transfers it to the top of the cutting table 108. The output end of the first hydraulic rod 109 drives the pressure roller 110 to move downward to press the synchronous belt, and the vacuum suction plate 209 is reset. The output of motor 102 rotates to release a portion of the synchronous belt. Then, under the action of three sets of adjusting mechanisms 3, the three sets of second guide rollers 105 move to... Figure 3 At the height position shown, the synchronous belt passing above the two sets of second guide rollers 105 on the right side is in a horizontal state; The purpose of this is to allow for the rapid feeding and cutting of another set of feeding rollers 103 after all the synchronous belts on one set of feeding rollers 103 have been cut. In traditional technology, the heights of multiple sets of guide rollers are inconsistent. The suction device drives the disassembled synchronous belt discharge end to move up and down multiple times to pass through these guide rollers, which makes it extremely easy for the suction device to detach from the synchronous belt discharge end. This method avoids such a situation. S3. Under the action of the moving mechanism 4, the lifting frame 106, the multi-functional mechanism 5, the drive mechanism 6, and the offset detection mechanism 7 are moved together to the position shown in the figure. Figure 1 At the indicated position; according to the width of the synchronization belt, the two sets of light source spotlights 708 are driven to correspond to the front and rear positions of the synchronization belt respectively. The positions of the two sets of display panels 705 also correspond to the positions of the two sets of light source spotlights 708 respectively. The light source spotlights 708 emit point beams of light. At this time, the synchronization belt does not block the emitted laser. The camera 306 on the display panel 705 takes pictures and records the light spots mapped on the display panel 705. At this time, the light spots are the "deepest". S4. After that, the synchronous belt is conveyed. During the conveying process, the multi-functional drive mechanism 5 and the blower mechanism 8 work synchronously. The two sets of swing nozzles 501 can swing continuously back and forth along the upper surface of the synchronous belt to remove dust from the upper surface of the synchronous belt. They also play a role in smoothing the synchronous belt and preventing the synchronous belt from shifting due to wrinkles. In this swinging state, the ion wind snake air pump 504 is started. The bottom of the swing nozzle 501 is evenly provided with air holes. The compressed airflow blows ions onto the surface of the synchronous belt, which can effectively remove static electricity from the surface of the synchronous belt. At the same time, the fan in the blower 812 rotates to blow off the dust on the lower surface of the synchronous belt. S5. When the synchronous belt reaches the cutting position, if the light spot captured by the camera 306 is still the "deepest", the cutter can directly cut. If the light spot disappears on the display panel 705 and the camera 306 cannot capture the light spot, it means that the synchronous belt has shifted position. For example, if the light spot disappears on the rear display panel 705, the synchronous belt has shifted to the rear, which blocks the light. This means that the synchronous belt conveyed to the cutting table 108 has also shifted. Then, under the action of the auxiliary mechanism 2, the vacuum suction plate 209 is used to attract the synchronous belt and adjust its position. After correction, it can be cut. This invention features fully automated operation, requiring no assistance from staff, thus meeting the needs of workers and representing a substantial improvement. To a certain extent, it facilitates widespread adoption.
