Description

[0002] In the garment manufacturing industry, during the processing of garment pieces, the pieces are often stacked up with dozens or even hundreds of pieces of cloth and cut into specific shapes on a large cutting table. In actual production, in order to avoid the influence of color difference of the original cloth, each piece needs to be numbered in the stacking order to facilitate the identification of the cloth in the subsequent sewing section.

[0003] At present, the folding of cut pieces is mostly completed by a combination of a flipping mechanism and an electrostatic adsorption device. It is impossible to remove impurities such as dust and cloth remaining on the surface of the cut pieces, which is prone to undesirable phenomena such as incomplete printed labels. In addition, when electrostatic adsorption is used for folding, it is easy to be affected by static electricity and fiber fibers between the cut pieces, resulting in wrinkles on the cut pieces that have not yet completed the printed labels, seriously affecting the flatness of the cut pieces to be processed. Therefore, at this stage, the market is in urgent need of a folding mechanism for a cut piece numbering machine with a smoothing and wrinkle-proof function to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that at present, the folding work of the cutting pieces is mostly completed by combining a turning mechanism and an electrostatic adsorption device, which cannot remove impurities such as dust, cloth, etc. remaining on the surface of the cutting pieces, and is prone to undesirable phenomena such as incomplete printed numbers. In addition, when electrostatic adsorption is used for folding, it is easy to be affected by static electricity and fiber threads between the cutting pieces, resulting in wrinkles on the cutting pieces that have not completed the printed numbers, seriously affecting the flatness of the cutting pieces to be processed.

[0026] 1. In the present invention, the designed thorny roller shaft, air pump, elastic connecting pipe, flow distribution tube, flow equalization mechanism, third bearing, second motor, hydraulic cylinder, connecting sleeve, threaded rod and locking nut cooperate with each other, so that the cloth after the label printing can be automatically folded and rolled up. During the rolling process, the folding area per unit time is small, and the impact on the cloth without the label printing is low. In the rolling process, the air flow can also be used to smooth the cloth without the label printing, and the cloth fragments remaining on the surface of the cloth can be removed, thereby ensuring the quality and completion of the label printing mechanism after the label printing is completed, and facilitating operation and debugging, thereby reducing the use cost and maintenance cost of the equipment.

[0027] 2. In the present invention, through the mutual cooperation of the barbed roller shaft, the first side plate seat, the hydraulic cylinder, the second motor, the first bearing, and the first bearings, the second motor is selected as a brake motor. Operating the second switch causes the second motor to run. During operation, the second motor can directly apply torque to the barbed roller shaft. The barbed roller shaft rotates within the first bearing through the first rotating shaft, causing the inclination angle of the originally bottom row of barbs to be a (-90° < a < -150°). Then, operate the second switch again to stop the second motor. Next, operate the third switch to make the hydraulic cylinder retract, thereby driving the barbed roller shaft downward and slowly piercing the barbs on the barbed roller shaft into the fabric. The piercing depth of the barbs is proportional to the thickness of the fabric. Finally, operate the second switch again to make the second motor run, and the fabric after printing the number can be wound onto the barbed roller shaft. During the winding process, it is also necessary to operate the third switch to make the hydraulic cylinder extend. The unprocessed fabric to be printed with numbers is only affected by other small forces such as the pulling force of the fiber filaments between it and the fabric after printing the number and the electrostatic adsorption force. Through the mutual cooperation of the designed lock nut, threaded rod, rocker, connecting sleeve, shunt cylinder, flow equalizing mechanism, third bearing, elastic connecting pipe, and air pump, first adjust the inclination angle of the flow equalizing mechanism according to the fabric model. Loosen the lock nut first, and then drive the shunt cylinder to rotate within the third bearing by twisting the threaded rod, so that the orientation of the flow equalizing mechanism can be adjusted. After completing the positioning of the flow equalizing mechanism, twist the fastening bolt again to complete the positioning of the orientation of the flow equalizing mechanism. During the process of the barbed roller shaft winding the fabric after printing the number, operate the fourth switch to make the air pump run. During operation, the air pump can introduce the air flow into the shunt cylinder through the connecting pipe, and finally evenly spray the air flow on the surface of the fabric after printing the number through the flow equalizing mechanism. Since the fabric has a certain air permeability, the air flow acting on the unprinted fabric will be more uniform by using the fabric after printing the number. At the same time, the flow rate of the air flow can also be weakened to avoid the influence of excessive air flow rate on the flatness of the unprinted fabric.

[0028] 3. In the present invention, through the designed sliding seat, sliding groove, threaded cylinder, threaded column, first rotating shaft, first motor, and second bearing, operate the first switch to make the first motor run. During operation, the first motor can directly apply torque to the threaded column, causing the threaded column to rotate within the threaded cylinder, enabling the barbed roller shaft to move at a certain uniform speed during the process of winding the fabric after printing the number.

[0037] 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 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 creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-6, the present invention provides a technical solution: a folding mechanism for a piece numbering machine with a function of smoothing and anti-wrinkling, including a frame 1. The number of frames 1 is two, and the same transmission mechanism 2 is arranged between the two frames 1. A sliding groove 3 is opened at the top of the frame 1. A sliding seat 4 is slidably connected in the sliding groove 3. A hydraulic cylinder installation groove 11 is opened at the top of the sliding seat 4. A hydraulic cylinder 12 is arranged in the hydraulic cylinder installation groove 11. The top end of the hydraulic cylinder 12 is fixedly connected to a first side plate seat 13. And the same barbed roller shaft 14 is arranged between the two first side plate seats 13. Through the mutual cooperation among the designed barbed roller shaft 14, the first side plate seat 13, the hydraulic cylinder 12, the second motor 17, the first bearing 8 and the first bearing 8, the second motor 17 is a brake motor. Operating the second switch 32 makes the second motor 17 run. During the operation of the second motor 17, the torque can be directly applied to the barbed roller shaft 14. The barbed roller shaft 14 rotates in the first bearing 8 through the first rotating shaft 7, so that the inclination angle of the row of barbs originally at the bottom is a (-90° < a < -150°). Then, operate the second switch 32 again to stop the second motor 17. Then, operate the third switch 33 to make the hydraulic cylinder 12 retract. Thus, the barbed roller shaft 14 can be driven to move downward, and the barbs on the barbed roller shaft 14 are slowly inserted into the fabric. And the insertion depth of the barbs is proportional to the thickness of the fabric. Finally, operate the second switch 32 again to make the second motor 17 run, and the fabric after printing the number can be wound on the barbed roller shaft 14. And during the winding process, it is also necessary to operate the third switch 33 to make the hydraulic cylinder 12 extend. The unprocessed fabric to be printed is only affected by other small forces such as the pulling force of the fiber filaments between the fabric after printing the label and the electrostatic adsorption force. One side of the first side plate seat 13 is fixedly connected to one side of the support seat 19 close to it through a bridge-shaped frame 18. The top of the support seat 19 is fixedly connected to the bottom of the body of the air pump 20 through a shock absorber seat. The output port of the air pump 20 is connected to the top of the flow dividing cylinder 22 through an elastic connecting pipe 21. And the elastic connecting pipe 21 is clamped on the surface of the support seat 19. The surface of the flow dividing cylinder 22 is embedded with a flow equalizing mechanism 23.

[0039] Specifically, as Figure 1 shown, a threaded cylinder 5 is clamped on the side of the sliding seat 4. A threaded column 6 is threadedly connected in the threaded cylinder 5. The end of the threaded column 6 is fixedly connected to a first rotating shaft 7. The surface of the first rotating shaft 7 is sleeved with a first bearing 8. The first bearing 8 is clamped at the end face inside the sliding groove 3. And the end of one of the first rotating shafts 7 is fixedly connected to the end of the output shaft of the first motor 9.

[0040] Specifically, as Figure 1 shown, a groove 10 is opened at the end of the barbed roller shaft 14. A second motor 17 is detachably installed in the groove 10. The end of the output shaft of the second motor 17 is fixedly connected to one side of one of the first side plate seats 13 close to it.

[0041] Specifically, Figure 1 As shown, the end of the thorn-in roller shaft 14 is embedded and fixedly connected with a second rotating shaft 15 , and a second bearing 16 is sleeved on the surface of the second rotating shaft 15 , and the second bearing 16 is clamped on the end surface of another first side plate seat 13 .

[0042] Specifically, Figure 1 As shown, the bottom of the support seat 19 is fixedly connected to two second side plate seats 25, and the diverter tube 22 is located between the two second side plate seats 25. The surface of the diverter tube 22 is sleeved with a third bearing 24, and the third bearing 24 is clamped on a surface close to one of the second side plate seats 25.

[0043] Specifically, Figure 5 As shown, the end of the shunt cylinder 22 away from the third bearing 24 is fixedly connected to a threaded rod 27, the surface of the threaded rod 27 is sleeved with a connecting sleeve 26, and the connecting sleeve 26 is clamped on the side close to the other second side plate seat 25, the surface of the threaded rod 27 is threadedly connected with a locking nut 28, and the surface of the locking nut 28 is fixedly connected with a rocker 29. Through the designed locking nut 28, threaded rod 27, rocker 29, connecting sleeve 26, shunt cylinder 22, flow equalizing mechanism 23, third bearing 24, elastic connecting tube 21 and air pump 20, the inclination angle of the flow equalizing mechanism 23 is first adjusted according to the model of the fabric, the locking nut 28 is first loosened, and then the shunt cylinder 22 is driven to rotate in the third bearing 24 by twisting the threaded rod 27. In this way, the direction of the flow equalizing mechanism 23 can be adjusted. After the positioning work of the flow equalizing mechanism 23 is completed, the fastening bolts are twisted again to complete the positioning work of the direction of the flow equalizing mechanism 23. During the process of the thorny roller shaft 14 winding up the cloth after printing the label, the fourth switch 34 is operated to run the air pump 20. During the operation of the air pump 20, the air flow can be introduced into the diversion cylinder 22 through the connecting pipe, and finally the air flow is evenly sprayed on the surface of the cloth with the printed label through the flow equalizing mechanism 23. Since the cloth has a certain air permeability, the cloth with the printed label can make the air flow acting on the cloth with the unfinished printed label more uniform. At the same time, the flow rate of the air flow can also be weakened to avoid the excessive air flow rate affecting the flatness of the cloth with the unfinished printed label.

[0044] Specifically, Figure 1As shown, the cross-sectional shapes of the sliding seat 4 and the sliding groove 3 when viewed from the side are both rectangular structures, and the inner diameter of the sliding groove 3 is matched with the outer diameter of the sliding seat 4. Through the designed sliding seat 4, sliding groove 3, threaded barrel 5, threaded column 6, first rotating shaft 7, first motor 9 and second bearing 16, the first switch 31 is operated to operate the first motor 9. During operation, the first motor 9 can directly apply torque to the threaded column 6, so that the threaded column 6 rotates in the threaded barrel 5, so that the barbed roller shaft 14 can move at a certain uniform speed during the process of winding up the printed numbered cloth.

[0045] Specifically, Figure 1 As shown, the thorny roller shaft 14 is composed of a roller shaft and thorns, and the size of the thorns is 0.5 mm, and the thorns are regular linear structures.

[0046] Specifically, Figure 1 As shown, the input end of the first motor 9 is electrically connected to the output end of the first switch 31 through a wire, the input end of the second motor 17 is electrically connected to the output end of the second switch 32 through a wire, the input end of the hydraulic cylinder 12 is electrically connected to the output end of the third switch 33 through a wire, and the input end of the air pump 20 is electrically connected to the output end of the fourth switch 34 through a wire.

[0047] Specifically, Figure 1 As shown, the input ends of the first switch 31, the second switch 32, the third switch 33 and the fourth switch 34 are electrically connected to the output end of the power supply 30 through wires, and the first switch 31, the second switch 32, the third switch 33, the fourth switch 34 and the power supply 30 are all arranged on the surface of the frame 1.

[0048] Working principle: When in use, the second motor 17 is selected as a brake motor. Operate the second switch 32 to make the second motor 17 run. During operation, the second motor 17 can directly apply torque to the barbed roller shaft 14. The barbed roller shaft 14 rotates in the first bearing 8 through the first rotating shaft 7, causing the inclination angle of the row of barbs originally at the bottom to be a (-90° < a < -150°). Then, operate the second switch 32 again to stop the second motor 17. Next, operate the third switch 33 to make the hydraulic cylinder 12 retract, thereby driving the barbed roller shaft 14 downward and slowly inserting the barbs on the barbed roller shaft 14 into the fabric. The penetration depth of the barbs is proportional to the thickness of the fabric. Finally, operate the second switch 32 again to make the second motor 17 run, and the fabric after printing the number can be wound on the barbed roller shaft 14. During the winding process, it is also necessary to operate the third switch 33 to make the hydraulic cylinder 12 extend. The unprocessed fabric to be printed is only affected by other small forces such as the pulling force of the fiber filaments between the fabric after printing the number and the electrostatic adsorption force. First, adjust the inclination angle of the flow equalizing mechanism 23 according to the type of the fabric. Loosen the locking nut 28 first, and then drive the flow dividing cylinder 22 to rotate in the third bearing 24 by turning the threaded rod 27, so that the orientation of the flow equalizing mechanism 23 can be adjusted. After completing the positioning of the flow equalizing mechanism 23, turn the fastening bolt again to complete the positioning of the orientation of the flow equalizing mechanism 23. During the process of the barbed roller shaft 14 winding the fabric after printing the number, operate the fourth switch 34 to make the air pump 20 run. During operation, the air pump 20 can introduce air flow into the flow dividing cylinder 22 through the connecting pipe, and finally evenly spray the air flow on the surface of the fabric after printing the number through the flow equalizing mechanism 23. Since the fabric has a certain air permeability, the air flow acting on the unprinted fabric will be more uniform by using the fabric after printing the number. At the same time, the flow rate of the air flow can also be weakened to avoid the influence of too large air flow rate on the flatness of the unprinted fabric. During operation, the first motor 9 can directly apply torque to the threaded column 6, causing the threaded column 6 to rotate in the threaded barrel 5, so that the barbed roller shaft 14 can move at a certain uniform speed during the process of winding the fabric after printing the number.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
