[0008] The present invention is further configured as follows: the buffer assembly includes two through slots, the two through slots are respectively opened on the opposite side of the shell and the fixed plate, and the two ends of the two active rotating shafts are respectively passed through the interior of the two through slots, and the shell is symmetrically provided with two slide rails on the side close to the roller, and one end of the two driven rotating shafts is respectively inserted into the interior of the two slide rails.

[0009] The present invention is further configured as follows: two springs are symmetrically fixedly connected to the inner side wall of the through slot corresponding to the shell, and baffles are connected to the opposite sides of the two springs, and the two baffles are respectively fitted with the two active rotating shafts in the corresponding through slot.

[0015] (2) By setting up an angle adjustment component, when the two active shafts slide inside the through groove, the corresponding driven shaft will slide in the corresponding slide rail, causing the overall angle of the roller to change, thereby changing the contact surface between the roller and the material, which not only alleviates the problem of entanglement between the material and the roller, but also changes the traction force of the device on the material, thereby improving the functionality of the device;

[0016] (3) If the material is offset or folded during transportation, the magnetic slider on one chuck gradually moves toward the axis center, and the magnetic slider on the other chuck gradually moves away from the axis center, thereby switching the driven chuck. This method can cause the two chucks and the corresponding rollers to rotate in opposite directions while the motor does not stop, so that the material can be transported from bottom to top, and the offset and folded position of the material can be refluxed and transported, thereby solving the problem of material offset and folding.

[0031] Example

[0032] See also Figure 1-10 , the present invention provides the following technical solutions:

[0033] A device for automatically adjusting the traction force of a flat knitting machine roller in sections includes a traction assembly 1. Two guide assemblies 3 are installed on the top of the traction assembly 1. A drive assembly 2 is installed on one side of the traction assembly 1. A chuck adjustment assembly 4 is installed inside the drive assembly 2. A buffer assembly 5 is installed at the end of the traction assembly 1 close to the drive assembly 2. An angle adjustment assembly 7 is installed inside the buffer assembly 5. The angle adjustment assembly 7 is in contact with the traction assembly 1. The drive assembly 2 is used to drive the chuck adjustment assembly 4 and the traction assembly 1 to rotate, so that the traction assembly 1 pulls and conveys the material. When passing through the traction assembly 1, the material is first guided by the guide assembly 3 so that the material can be kept within the length range of the traction assembly 1. The chuck adjustment assembly 4 is used to adjust the rotation speed of the traction assembly 1, thereby quickly adjusting the traction force. The angle adjustment assembly 7 is used to adjust the spacing of the conveyed materials in the middle of the traction assembly 1, so that the traction assembly 1 can convey materials of different thicknesses.

[0034] The traction assembly 1 includes a shell 11 and a fixed plate 13. Two connecting frames 16 are provided between the shell 11 and the fixed plate 13. The top ends of the two connecting frames 16 are rotatably connected to the driven shaft 15. The bottom ends of the two connecting frames 16 are rotatably connected to the driving shaft 14. One end of the driving shaft 14 and the driven shaft 15 extends to the interior of the shell 11. The other ends of the driving shaft 14 and the driven shaft 15 pass through one side of the fixed plate 13. A driving shaft 14 and a driven shaft 15 are a group. The outer wall of this group of driving shafts 14 and driven shafts 15 is provided with a roller 12. The connecting frame 16 It is used to support the driving rotating shaft 14 and the driven rotating shaft 15, so that there is a gap between the driving rotating shaft 14 and the driven rotating shaft 15. The driving rotating shaft 14 and the driven rotating shaft 15 cooperate to expand the roller 12 and drive the roller 12 to transmit. The two rollers 12 cooperate to convey the material. When conveying, the material first passes through the two driven rotating shafts 15 and then passes through the two driving rotating shafts 14. The diameter of the driven rotating shaft 15 is smaller than the diameter of the driving rotating shaft 14, so that the expanded roller 12 is triangular when viewed from the side, which increases the contact area with the material while ensuring the material transportation, and avoids the material from being offset.

[0035] The driving assembly 2 includes a motor 22, which is sleeved on the outer wall of the shell 11. A cover plate 21 is installed on the side of the motor 22 away from the shell 11. The output end of the cover plate 21 extends to the interior of the shell 11 and is connected to a driving wheel 23. The driving wheel 23 is connected to the chuck adjustment assembly 4. The motor 22 is installed on one side of the cover plate 21, and the driving wheel 23 is enclosed in the shell 11 through the cover plate 21, so that the driving wheel 23 is not affected by the external environment when working. The motor 22 is used to drive the driving wheel 23 to rotate, and the driving wheel 23 provides power for the operation of the chuck adjustment assembly 4.

[0036] The chuck adjustment assembly 4 is divided into two groups. The two groups of chuck adjustment assemblies 4 correspond to the two active rotating shafts 14. The two groups of chuck adjustment assemblies 4 include chucks 41. The chucks 41 are sleeved and installed on the outer side walls of the corresponding active rotating shafts 14. The outer side walls of the two chucks 41 are evenly connected with gear teeth 42. The two gear teeth 42 mesh with each other. The chucks 41 are evenly provided with slide grooves 44 on the side away from the housing 11. The inside of the slide grooves 44 is slidably connected with a magnetic slider 43. The magnetic slider 43 on one side of the chuck 41 is a group. The outer side wall of the active wheel 23 is sleeved with two transmission belts 45. The two transmission belts 45 are respectively sleeved on the outer sides of the two groups of magnetic sliders 43. The active wheel 23 is used to drive the two transmission belts 45 for transmission, and the two transmission belts 45 are respectively sleeved on the outside of the two groups of magnetic sliders 43, so that the two transmission belts 45 respectively drive the corresponding magnetic sliders 43, the chucks 41 and the active rotating shaft 14 to rotate, so that the active rotating shaft 14 can drive the roller 12 to transmit and provide power for material transportation;

[0037] The two sets of magnetic sliders 43 work alternately. That is, when the magnetic slider 43 on one chuck 41 supports the corresponding transmission belt 45, this set of magnetic sliders 43 can drive the corresponding chuck 41 and the driving shaft 14 to rotate. As this set of magnetic sliders 43 continues to move away from the axis of the chuck 41, the corresponding transmission belt 45 is continuously stretched.

[0038] Since the diameter of the driving wheel 23 is fixed, when the diameter of the contact position between the magnetic slider 43 and the transmission belt 45 is smaller than the diameter of the driving wheel 23, the corresponding rotation speed of the chuck 41 is faster;

[0039] When the diameter of the contact position between the magnetic slider 43 and the transmission belt 45 is equal to the diameter of the driving wheel 23, the rotation speed of the corresponding chuck 41 is consistent with the rotation speed of the driving wheel 23;

[0040] When the diameter of the contact position between the magnetic slider 43 and the transmission belt 45 is larger than the diameter of the driving wheel 23 , the rotation speed of the corresponding chuck 41 is lower than the rotation speed of the driving wheel 23 ;

[0041] This method can perform multi-stage and multi-state control;

[0042] At this time, the magnetic slider 43 on the other chuck 41 is located close to the axis of the chuck 41, resulting in a gap between the other transmission belt 45 and the magnetic slider 43 outside the other chuck 41. This transmission belt 45 cannot provide a rotational force to the corresponding chuck 41. The chuck 41 with a rotational force meshes with the other chuck 41 through the gear teeth 42, allowing the two chucks 41 to rotate towards each other.

[0043] Conversely, when the magnetic slider 43 on one chuck 41 is displaced, the magnetic slider 43 on the other chuck 41 is displaced synchronously;

[0044] That is, when the magnetic slider 43 on one chuck 41 gradually moves toward the axis center, the magnetic slider 43 on the other chuck 41 gradually moves to a position away from the axis center, thereby switching the driven chuck 41 .

[0045] The buffer assembly 5 includes two through slots 51, and the two through slots 51 are respectively opened on the side opposite to the housing 11 and the fixed plate 13, and the two ends of the two active rotating shafts 14 are respectively arranged inside the two through slots 51. Two slide rails 54 are symmetrically opened on the side of the housing 11 close to the roller 12, and one end of the two driven rotating shafts 15 is respectively inserted into the inside of the two slide rails 54. Two springs 52 are symmetrically fixedly connected to the inner side walls of the through slots 51 corresponding to the housing 11. A baffle 53 is connected to the opposite side of the two springs 52. The two baffles 53 are respectively fitted with the two active rotating shafts 14 in the corresponding through slots 51;

[0046] The angle adjustment assembly 7 includes a bidirectional cylinder 71, which is respectively installed in the through slot 51 opened on one side of the housing 11. The bidirectional cylinder 71 is located between the two active shafts 14. The two piston rods of the bidirectional cylinder 71 are connected to a push plate 72, and one side of the push plate 72 is in contact with the outer wall of the corresponding active shaft 14.

[0047] Ball bearings are installed at the joints between the baffle 53 and the push plate 72 and the active shaft 14 to reduce the friction between the baffle 53 and the push plate 72 and the active shaft 14, that is, when the active shaft 14 rotates on the inner walls of the baffle 53 and the push plate 72, it is not affected by the friction.

[0048] The bidirectional cylinder 71 is used to push the two push plates 72 to slide inside the corresponding through slots 51. When the two push plates 72 move away from each other, the corresponding two driving shafts 14 will slide inside the through slots 51 and move away from each other. When moving away from each other, the driving shafts 14 press the corresponding baffles 53 and springs 52, causing the springs 52 to be compressed.

[0049] On the contrary, when the two push plates 72 approach each other, the corresponding two driving shafts 14 will approach each other, and the elastic force of the spring 52 pushes the baffle 53 to slide toward the position of the driving shaft 14, causing the driving shaft 14 to slide toward the position of the push plates 72, thereby maintaining the push plates 72 in contact with the corresponding driving shafts 14.

[0050] When the position of the driving shaft 14 changes, the corresponding driven shaft 15 will also be displaced;

[0051] That is, when the two active rotating shafts 14 slide away from each other inside the through slot 51, the corresponding driven rotating shaft 15 will slide in the corresponding slide rail 54 toward the through slot 51. Conversely, when the two active rotating shafts 14 slide toward each other inside the through slot 51, the corresponding driven rotating shaft 15 will slide in the corresponding slide rail 54 toward the direction away from the through slot 51, causing the overall angle of the roller 12 to change, thereby adjusting the contact surface between the roller 12 and the material to avoid entanglement of the material and the roller 12.

[0052] The two guide assemblies 3 each include a support frame 31, which are respectively mounted on the top of the shell 11 and the fixed plate 13. An adjusting rod 32 is provided on one side of the support frame 31, and the end of the adjusting rod 32 close to the roller 12 is connected to a Y-shaped frame 33. The Y-shaped frame 33 is located above the gap between the two rollers 12, so that the material first passes through the two Y-shaped frames 33 before being conveyed, and then enters the gap between the two rollers 12 for conveying. The adjusting rod 32 slides inside the support frame 31, thereby adjusting the position of the Y-shaped frame 33 to extend above the roller 12, so that the Y-shaped frame 33 can adjust the width of the guide according to the width of the material.

[0053] Two infrared sensors 6 are symmetrically mounted on one side of the housing 11 near the roller 12. The two infrared sensors 6 are located on either side of the corresponding support frame 31, and the infrared sensors 6 are located on the top inclined surface of the roller 12. The infrared sensors 6 are used to monitor the surface of the roller 12. When the material is entangled with the roller 12, the infrared sensors 6 detect a change in the thickness of the surface of the roller 12. At this time, the angle of the roller 12 is adjusted through the angle adjustment component 7 and an alarm is issued.

[0054] Specifically, the staff passes the material through the Y-shaped frame 33 and between the two rollers 12 in sequence, and pushes the adjustment rod 32 to slide inside the support frame 31, thereby adjusting the position of the Y-shaped frame 33 extending above the rollers 12, so that the Y-shaped frame 33 can adjust the guide width according to the width of the material;

[0055] The device is connected to an external control system, which controls the automatic operation of the device. The control system controls the motor 22 to start, and the motor 22 drives the driving wheel 23 to rotate. The driving wheel 23 drives two transmission belts 45 for transmission, and the two transmission belts 45 are respectively sleeved on the outside of the two sets of magnetic sliders 43, so that the two transmission belts 45 respectively drive the corresponding magnetic sliders 43, the chuck 41 and the driving shaft 14 to rotate, so that the driving shaft 14 can drive the rollers 12 to transmit and provide power for material transportation. The two rollers 12 cooperate with the opposite transmission to transport the material. When transporting, the material first passes through the two driven shafts 15 and then passes through the two driving shafts 14. The diameter of the driven shaft 15 is smaller than the diameter of the driving shaft 14, so that the stretched rollers 12 are viewed from the side as a triangle, which increases the contact surface with the material while ensuring material transportation and avoids the deviation of the material.

[0056] The infrared sensor 6 is used to monitor the surface of the roller 12. When the material is entangled with the roller 12, the infrared sensor 6 detects that the thickness of the surface of the roller 12 changes. At this time, the infrared sensor 6 transmits a signal to the control system to give an alarm.

[0057] At this time, the control system controls the two-way cylinder 71 to start, and the two-way cylinder 71 pushes the two push plates 72 to slide inside the corresponding through slots 51. When the two push plates 72 move away from each other, the corresponding two driving shafts 14 will slide inside the through slots 51 and move away from each other. When the driving shafts 14 move away from each other, they squeeze the corresponding baffles 53 and springs 52, causing the springs 52 to be compressed. When the position of the driving shaft 14 changes, the corresponding driven shaft 15 will also move.

[0058] That is, when the two driving shafts 14 slide away from each other inside the through slot 51, the corresponding driven shafts 15 will slide in the corresponding slide rails 54 toward the through slot 51, causing the overall angle of the roller 12 to change, thereby reducing the contact area between the roller 12 and the material, preventing the material from being entangled with the roller 12, and reducing the traction force of the device;

[0059] At the same time, the control system controls the magnetic slider 43 on one chuck 41 to continuously move away from the axial position of the chuck 41, and the corresponding transmission belt 45 is continuously stretched. When the diameter of the contact position between the magnetic slider 43 and the transmission belt 45 is larger than the diameter of the driving wheel 23, the rotation speed of the corresponding chuck 41 is lower than the rotation speed of the driving wheel 23. At this time, the rotation speed of this chuck 41 and the corresponding driving shaft 14 slows down. Since the two chucks 41 are engaged with each other through the gear teeth 42, the speed of the two chucks 41 rotating in opposite directions can be reduced, thereby reducing the transmission speed of the roller 12, thereby optimizing the effect of reducing the traction force of the device.

[0060] At this time, the magnetic slider 43 on the other chuck 41 is located close to the axis of the chuck 41, resulting in a gap between the other transmission belt 45 and the magnetic slider 43 outside the other chuck 41. This transmission belt 45 cannot provide rotational force to the corresponding chuck 41.

[0061] On the contrary, when the traction force needs to be increased, the control system controls the piston rod of the two-way cylinder 71 to contract, causing the two push plates 72 to approach each other, and the corresponding two active shafts 14 to approach each other. The elastic force of the spring 52 pushes the baffle 53 to slide toward the position of the active shaft 14, causing the active shaft 14 to slide toward the position of the push plate 72, thereby maintaining the push plate 72 and the corresponding active shaft 14 in a state of contact. The two active shafts 14 slide inside the through slot 51 and approach each other, and the corresponding driven shaft 15 will slide in the corresponding slide rail 54 in the direction away from the through slot 51, causing the overall angle of the roller 12 to change, thereby increasing the contact area between the roller 12 and the material, and increasing the traction force of the device on the material;

[0062] At the same time, the control system controls a magnetic slider 43 on a chuck 41 to gradually move toward the axis position. When the diameter of the contact position between the magnetic slider 43 and the transmission belt 45 is smaller than the diameter of the driving wheel 23, the corresponding rotation speed of the chuck 41 is faster, while increasing the contact surface of the roller 12 with the material, it can optimize and improve the traction force of the device on the material.

[0063] In this process, there is no need to set multiple gears of inconsistent sizes, and the traction force of the device can be adjusted without manually switching between multiple gears.

[0064] If the material is offset or folded during transportation, the magnetic slider 43 on one chuck 41 gradually moves toward the axis center position, and the magnetic slider 43 on the other chuck 41 gradually moves to a position away from the axis center, thereby switching the driven chuck 41. This method can cause the two chucks 41 and the corresponding rollers 12 to rotate in opposite directions while the motor 22 continues to rotate, so that the material can be transported from bottom to top, and the offset and folded positions of the material can be refluxed and transported, thereby solving the problem of material offset and folding.
