Description

Technical Field

[0001] The present invention relates to the technical field of inkjet positioning machines, in particular to a double-head lock-edge inkjet positioning machine. Background Art

[0002] An inkjet marking machine is a device that uses inkjet technology to mark points on the surface of an object. It sprays ink in the form of tiny droplets onto the surface of the object to form the required point marks. This allows for rapid and continuous marking, improving production efficiency and reducing production costs. It is suitable for marking the surfaces of objects made of various materials and is widely used in the electronics, automotive, machinery, medical, packaging and other industries. Based on different materials and marking requirements, the appropriate ink and nozzle can be selected to ensure the quality and effect of the marking. Furthermore, by controlling the inkjet speed and pressure, the uniformity and stability of the ink jet can be ensured to avoid problems such as blurring or deformation.

[0003] In the actual use of the inkjet marking machine, due to the inconsistent surface roughness of different batches of fabrics and the different friction between them and the conveyor belt, the fabric with a smoother surface may slip on the conveyor belt, so that its actual conveying speed is different from the established speed. When the inkjet machine marks the fabric at the established speed, there may be an error between the actual mark position and the established mark position, resulting in deviations in subsequent cutting and other processes. The size of the produced product may not meet the standard. For this reason, we propose a double-head lock-edge inkjet marking machine. Summary of the Invention

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0035] See also Figure 1-13The present invention provides a technical solution: a double-head lock-edge inkjet point-positioning machine, comprising an operating table 1, an automatic feeding device 2 and a self-joining head device 3 fixedly mounted on the operating table 1 (the automatic feeding device 2 and the self-joining head device 3 are both existing known structures, so the present invention will not be described in detail), a first slide rail 4 and a second slide rail 6 are fixedly mounted on the operating table 1, a first joining manipulator 5 is slidably mounted on the first slide rail 4, a second joining manipulator 7 is slidably mounted on the second slide rail 6, a cutting device 8 for cutting cloth is fixedly mounted on the operating table 1, and a lifting rod 9 is slidably mounted on the cutting device 8. When the cloth is removed from the operating table 1 When conveyed out, the first material receiving robot 5 clamps one end of the cloth and moves along the first slide rail 4 to unfold the cloth to prevent the cloth from piling up on the operating table 1. When the cloth is conveyed to a certain length, the first material receiving robot 5 retracts and folds the cloth in half, and then the lifting rod 9 lifts the cloth to facilitate the second material receiving robot 7 to clamp the cloth, and then the cutting device 8 cuts it again along the cloth fracture so that the fractures at both ends of the cut cloth overlap. The second material receiving robot 7 clamps the cut cloth and moves along the second slide rail 6 to the self-feeding machine head device 3. The self-feeding machine head device 3 sews the two ends of the cut cloth so that the cut cloth is sewn into a circle as a whole.

[0036] A conveyor frame 10 is fixedly installed on the operating table 1, and a double-head overlocking machine 11 for locking the edge of the cloth is fixedly installed on the conveyor frame 10. Two transmission shafts 12 are rotatably installed on the conveyor frame 10, and a conveyor belt 13 is connected between the two transmission shafts 12. A conveyor roller 14 is provided above each transmission shaft 12, and a plurality of first elastic members 19 are rotatably installed on each conveyor roller 14. The elastic force of the first elastic member 19 always pushes the conveyor roller 14 toward the conveyor belt 13, increasing the friction between the conveyor roller 14 and the cloth, so that the conveyor roller 14 and the conveyor belt 13 clamp the cloth, reducing the slippage of the cloth during the conveying process, and one end of each first elastic member 19 is fixedly connected to the conveyor frame 10. Several elastic blocks 17 are fixedly installed, and several elastic grooves 18 that match the elastic blocks 17 are provided on the surface of the conveyor belt 13. The elastic blocks 17 on each conveyor roller 14 are arranged in multiple rows and crosses, and the elastic grooves 18 on the conveyor belt 13 are also arranged in multiple rows and crosses that match them. A first gear 15 is fixedly installed at both ends of each transmission shaft 12, and a second gear 16 that meshes with the first gear 15 is fixedly installed at both ends of each conveyor roller 14. The length of the protruding teeth of the first gear 15 and the length of the protruding teeth of the second gear 16 are both greater than the thickness of the cloth. The first gear 15 and the second gear 16 are always in a meshing state, and the movement speed of the conveyor roller 14 is consistent with the movement speed of the conveyor belt 13. When the cloth passes through the automatic conveyor When the material device 2 is transported to the conveyor belt 13, the two conveyor rollers 14 are pushed toward the conveyor belt 13 by the elastic force of the first elastic member 19, so that the cloth is clamped by the conveyor rollers 14 and the conveyor belt 13, and then the transmission shaft 12 is started to drive the conveyor belt 13 to move. The transmission shaft 12 drives the first gears 15 at both ends to rotate synchronously. Through the engagement of the first gear 15 and the second gear 16, the transmission shaft 12 will drive the conveyor rollers 14 to rotate in the opposite direction, so that the cloth between the conveyor rollers 14 and the conveyor belt 13 is transported forward, and the elastic block 17 on the conveyor roller 14 cooperates with the elastic groove 18 on the conveyor belt 13 to increase the friction between the cloth and the conveyor belt 13 and the conveyor rollers 14, thereby reducing the slippage of the cloth. When the cloth batch is changed and the thickness changes, , the height of the conveyor roller 14 will change, and the elastic force of the first elastic member 19 will push the conveyor roller 14 toward the conveyor belt 13, so that the cloth is always clamped by the conveyor roller 14 and the conveyor belt 13, and because the length of the protruding teeth of the first gear 15 and the length of the protruding teeth of the second gear 16 are both greater than the thickness of the cloth, when the conveyor roller 14 drives the second gear 16 to move up and down, the first gear 15 and the second gear 16 are always in a meshing state, and through the speed change of the first gear 15 and the second gear 16, the movement speed of the conveyor roller 14 is always consistent with the movement speed of the conveyor belt 13, so that the conveyor roller 14 and the conveyor belt 13 always maintain stable transmission of the cloth. During the conveying process of the cloth, the double-head overlocking machine 11 continues to overlock both sides of the cloth at the same time.

[0037] An inkjet machine 20 is fixedly mounted on the conveyor frame 10 (the inkjet machine 20 is a known structure, so the present invention will not be described in detail). Several inkjet heads 38 for marking the cloth are slidably mounted on the inkjet machine 20. A device plate 39 is fixedly mounted on each inkjet head 38. A connecting member 40 is rotatably mounted on each device plate 39. A roller 41 is rotatably mounted on the lower end of each connecting member 40, and a third spring 42 is fixedly connected between each adjacent two connecting members 40. When the inkjet machine 20 is started, the inkjet head 38 will move downward and position and mark the cloth. During the descent of the inkjet head 38, it will drive the device plate 39 and the roller 41 on it. The connecting member 40 and the roller 41 descend synchronously, and the roller 41 will first contact the cloth. After the roller 41 contacts the cloth, it will drive the connecting member 40 to rotate with the rotating connection between the connecting member 40 and the device plate 39 as the center. When the connecting member 40 rotates, the third spring 42 thereon will provide resistance, so that the roller 41 is subjected to a downward force, so that when the roller 41 moves along the surface of the cloth, the surface of the cloth is flattened, making the surface of the cloth smoother, which is convenient for marking the pigment of the inkjet head 38 and reducing the marking error. When the inkjet head 38 is completed and recovered, the elastic force of the third spring 42 drives the connecting member 40 and the roller 41 to rotate in the opposite direction and reset.

[0038] The inkjet machine 20 is provided with a detection roller 21, and a plurality of second elastic members 22 are rotatably mounted on the detection roller 21. One end of each second elastic member 22 is fixedly connected to the inkjet machine 20. A plurality of elastic blocks 17 are also fixedly mounted on the detection roller 21. The elastic blocks 17 on the detection roller 21 are arranged in a multi-row cross-arrangement that matches the elastic grooves 18. The elastic force of the second elastic member 22 always pushes the detection roller 21 toward the conveyor belt 13, and the friction between the detection roller 21 and the cloth is increased through the cooperation between the elastic blocks 17 and the elastic grooves 18. The friction between the cloth and the detection roller 21 causes the detection roller 21 to rotate synchronously when the cloth moves, so that the detection roller 21 detects the actual movement speed of the cloth. A device slot 31 is provided in the inkjet machine 20, and the detection One end of the roller 21 is located in the device groove 31, and the third gear 23 is fixedly installed thereon. A fourth gear 24 is provided on the inner wall of the device groove 31, which is meshed with the third gear 23. The diameter of the fourth gear 24 is larger than that of the third gear 23. A limit rod 25 is slidably installed on the fourth gear 24. An adjustment groove 26 for limiting the limit rod 25 is provided on the fourth gear 24. The limit rod 25 is slidably installed in the adjustment groove 26 and needs to be adjusted by external force. A limit ring 27 is slidably installed on the limit rod 25, and a slide rod 28 is fixedly installed on the limit ring 27. A limit block 29 for limiting the slide rod 28 is fixedly installed on the inner wall of the device groove 31. When the detection roller 21 rotates, it will drive the third gear 23 to rotate synchronously. Through the third gear The meshing of 23 and the fourth gear 24 causes the fourth gear 24 to drive its upper limit rod 25 to rotate. Through the limiting of the limiting rod 25 by the limiting ring 27 and the limiting of the slide bar 28 by the limiting block 29, the limiting rod 25 will slide in the limiting ring 27 when performing a circular motion, and drive the limiting ring 27 and the slide bar 28 to reciprocate up and down. Moreover, since the diameter of the fourth gear 24 is greater than the diameter of the third gear 23, the third gear 23 must rotate multiple circles to drive the fourth gear 24 to rotate one circle, so that the slide bar 28 performs a reciprocating motion when the cloth is transmitted to a certain length. A device block 35 is provided above the slide bar 28, and a first spring 36 is fixedly installed on the upper end of the device block 35. A first induction ring 33 is fixedly installed on the upper end of the first spring 36. A sensing device 30 for controlling the inkjet head 38 is provided (the sensing device 30 is a known structure, so the present invention will not be described in detail). A second sensing ring 43 that cooperates with the first sensing ring 33 is fixedly installed at the lower end of the sensing device 30. An adjusting block 32 is fixedly installed on the sensing device 30. A sliding groove 44 for limiting the adjusting block 32 is provided on the inkjet machine 20. The adjusting block 32 is slidably installed in the sliding groove 44 and requires external force to adjust it. A pressure sensing component 34 is fixedly installed at the lower end of the sensing device 30. A second spring 37 is fixedly installed at the lower end of the pressure sensing component 34. The lower end of the second spring 37 is fixedly connected to the upper end of the device block 35. When the slide rod 28 moves upward, it contacts the device block 35 and pushes it upward.And drive the first spring 36 and the first induction ring 33 to move upward, and retract the second spring 37. When the slide bar 28 moves to the top of its motion trajectory, the first induction ring 33 will contact the second induction ring 43 on the induction device 30. At this time, the transmission shaft 12 will no longer move, the cloth will stop conveying, and the inkjet machine 20 will control the inkjet head 38 to descend to position and mark the cloth. According to the thickness of the cloth, the detection roller 21 will drive the third gear 23 and the fourth gear 24 to change their height and change the initial height of the slide bar 28. When the slide bar 28 moves to the highest point, the second spring 36 and the first induction ring 33 will contact the second induction ring 43 on the induction device 30. At this time, the transmission shaft 12 will no longer move, the cloth will stop conveying, and the inkjet machine 20 will control the inkjet head 38 to descend to position and mark the cloth. According to the thickness of the cloth, the detection roller 21 will drive the third gear 23 and the fourth gear 24 to change their height and change the initial height of the slide bar 28. When the slide bar 28 moves to the highest point, the second spring 37 will retract the second spring 36 and the first induction ring 33. The spring 37's retraction amplitude will also vary, and the pressure on the pressure-sensing element 34 will also vary. Based on the change in pressure on the pressure-sensing element 34, the inkjet head 38's descending amplitude is adjusted to match the inkjet head 38's descending height with the fabric thickness, improving the inkjet head 38's punctuation effect. When the inkjet interval distance needs to be changed, the position of the limit rod 25 within the adjustment slot 26 is manually changed, changing the radius of the limit rod 25's movement, causing the height of the slide bar 28's reciprocating motion to change. Simultaneously, the position of the adjustment block 32 within the sliding slot 44 is adjusted to drive the sensing device 30 to move to the appropriate height to match the slide bar 28's motion trajectory.

[0039] Working principle: When the cloth is transported to the conveyor belt 13 through the automatic feeding device 2, the two conveyor rollers 14 are pushed toward the conveyor belt 13 by the elastic force of the first elastic member 19, so that the cloth is clamped by the conveyor rollers 14 and the conveyor belt 13, and then the transmission shaft 12 is started to drive the conveyor belt 13 to move. The transmission shaft 12 drives the first gears 15 at both ends to rotate synchronously. Through the engagement of the first gear 15 and the second gear 16, the transmission shaft 12 will drive the conveyor rollers 14 to rotate in the opposite direction, so that the cloth between the conveyor rollers 14 and the conveyor belt 13 is transported forward, and through the cooperation of the elastic block 17 on the conveyor roller 14 and the elastic groove 18 on the conveyor belt 13, the friction between the cloth and the conveyor belt 13 and the conveyor rollers 14 is increased, thereby reducing the slippage of the cloth. When the cloth batches are changed and the thickness changes, the cloth is prevented from slipping. When the height of the conveyor roller 14 changes, the height of the conveyor roller 14 will change, and the elastic force of the first elastic member 19 will push the conveyor roller 14 toward the conveyor belt 13, so that the cloth is always clamped by the conveyor roller 14 and the conveyor belt 13, and because the length of the protruding teeth of the first gear 15 and the length of the protruding teeth of the second gear 16 are both greater than the thickness of the cloth, when the conveyor roller 14 drives the second gear 16 to move up and down, the first gear 15 and the second gear 16 are always in a meshing state, and through the speed change of the first gear 15 and the second gear 16, the movement speed of the conveyor roller 14 is always consistent with the movement speed of the conveyor belt 13, so that the conveyor roller 14 and the conveyor belt 13 always maintain stable transmission of the cloth. During the transmission of the cloth, the double-head overlocking machine 11 continues to overlock both sides of the cloth at the same time, and the second elastic member 19 is used to adjust the speed of the conveyor roller 14. The elastic force of 22 always pushes the detection roller 21 toward the conveyor belt 13, and the cooperation of the elastic block 17 and the elastic groove 18 increases the friction between the detection roller 21 and the cloth. Through the friction between the cloth and the detection roller 21, the cloth drives the detection roller 21 to rotate synchronously when it moves, so that the detection roller 21 detects the actual movement speed of the cloth. When the detection roller 21 rotates, it will drive the third gear 23 to rotate synchronously. Through the engagement of the third gear 23 and the fourth gear 24, the fourth gear 24 drives its upper limit rod 25 to rotate. Through the limitation of the limit rod 25 by the limit ring 27 and the limitation of the slide rod 28 by the limit block 29, the limit rod 25 will slide in the limit ring 27 when performing a circular motion, and drive the limit ring 27 and the slide rod 28. The rod 28 reciprocates up and down, and because the diameter of the fourth gear 24 is larger than that of the third gear 23, the third gear 23 rotates multiple times to drive the fourth gear 24 to rotate one circle, so that the slide bar 28 reciprocates once when the cloth is conveyed to a certain length. When the slide bar 28 moves upward, it contacts the device block 35, which pushes it upward and drives the first spring 36 and the first induction ring 33 to move upward, and retracts the second spring 37. When the slide bar 28 moves to the top of its motion trajectory, the first induction ring 33 contacts the second induction ring 43 on the induction device 30. At this time, the transmission shaft 12 will no longer move, the cloth will stop conveying, and the inkjet machine 20 will control the inkjet head 38 to move downward and position the cloth. During the descent of the inkjet head 38,The driving device plate 39 and the connecting member 40 thereon are synchronously lowered with the roller 41, and the roller 41 will first contact the cloth. After the roller 41 contacts the cloth, it will drive the connecting member 40 to rotate with the connecting member 40 and the device plate 39 as the center of the circle. When the connecting member 40 rotates, the third spring 42 thereon will provide resistance, so that the roller 41 is subjected to a downward force, so that when the roller 41 moves along the surface of the cloth, the surface of the cloth is flattened, making the surface of the cloth smoother, which is convenient for the marking of the inkjet head 38 pigment and reducing the marking error. When the inkjet head 38 is marked and recovered, the elastic force of the third spring 42 drives the connecting member 40 and the roller 41 to rotate in the opposite direction and reset. According to the thickness of the cloth, the detection roller 21 will drive the third gear 23 and the fourth gear 24 to change the height and change the initial height of the slide bar 28. When the slide bar 28 is moved to the highest point, the height of the slide bar 28 is affected by the thickness of the cloth, and the recovery amplitude of the second spring 37 will also be different. The pressure on the pressure sensing member 34 will also be different. According to the change in the pressure on the pressure sensing member 34, the inkjet head 38 is moved downward. The descending amplitude is adjusted to match the descending height of the inkjet head 38 with the thickness of the cloth, thereby improving the punctuation effect of the inkjet head 38. When the inkjet interval distance needs to be changed, the position of the limit rod 25 in the adjustment slot 26 is manually changed to change the radius of the movement of the limit rod 25, so that the height of the reciprocating motion of the slide bar 28 changes. At the same time, the position of the adjustment block 32 in the sliding slot 44 is adjusted to drive the sensing device 30 to move to a suitable height to match the motion trajectory of the slide bar 28. When the cloth is conveyed from the operating table 1, one end of the cloth is clamped by the first material receiving robot 5 and is moved along the second receiving robot 5. A slide 4 moves to unfold the fabric, preventing it from piling up on the operating table 1. When the fabric reaches a certain length, the first splicing robot 5 retracts and folds the fabric in half. A lifting rod 9 then lifts the fabric, allowing the second splicing robot 7 to grip it. A cutting device 8 then resects the fabric along its fractured edge, aligning the ends of the cut fabric. The second splicing robot 7 grips the cut fabric and moves along the second slide 6 to the self-splicing head device 3, which sews the ends of the cut fabric together, forming a circular shape.
