[0030] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0031] In this application, unless otherwise clearly defined or limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In this application, unless otherwise clearly defined or limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

[0033] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0034] In the traditional technology, during the production process of the cord, the cord needs to be cut by an angled cutting machine. During the use of the current equipment, due to the mutual extrusion and overlap between the cords stacked in the turnover box, there is a phenomenon of inconsistent tension during the pulling process. As a result, after the elastic cord passes through the cutter, the actual cut lengths are inconsistent. If multiple cords are cut simultaneously, the length differences of the cords will be more obvious.

[0035] Refer to Figure 1 , Figure 1The structural schematic diagram of the rope cutting device in one embodiment of the present application is shown. The rope cutting device provided in one embodiment of the present application is used to cut the rope 60. The rope cutting device includes a frame 10, a tensioning mechanism 20 and a cutting mechanism 30. The frame 10 plays a supporting and fixing role. The tensioning mechanism 20 and the cutting mechanism 30 are both arranged on the frame 10. The tensioning mechanism 20 is used to separate multiple ropes 60 to avoid winding between the ropes 60, and to pull the ropes 60 to the cutting mechanism 30. The cutting mechanism 30 is used to cut the ropes 60 to disconnect the ropes 60.

[0036] Combination Figure 2 As shown, Figure 2 The schematic diagram of the movement path of the rope 60 in one embodiment of the present application through the tensioning mechanism 20 and the cutting mechanism 30 is shown. The tensioning mechanism 20 is arranged on the frame 10, and the tensioning mechanism 20 includes a rotatable tensioning wheel 21, so that the rope 60 is pulled from the first side S1 of the tensioning wheel 21 to the second side S2 of the tensioning wheel 21. In the process of the tensioning wheel 21 pulling the rope 60 to move, the force on the rope 60 is relatively stable, and the uneven force caused by squeezing, knotting, etc. when the rope 60 is pulled up is solved.

[0037] Exemplarily, the elastic wheel 21 drives the rope 60 to move by rotating. When the rope 60 contacts the first side S1 of the elastic wheel 21, the elastic wheel 21 rotates under the action of friction, causing the rope 60 to rotate accordingly, and then moves to the second side S2 of the elastic wheel 21. Generally, after the rope 60 moves to the second side S2 of the elastic wheel 21, it will partially fall down under the action of gravity. The first side S1 and the second side S2 of the elastic wheel 21 are opposite sides.

[0038] The cutting mechanism 30 is also provided on the frame 10 and is arranged on the second side S2 of the elastic wheel 21. Thus, after the elastic wheel 21 pulls the rope 60 to the second side S2, it can be transferred to the cutting mechanism 30, and the cutting mechanism 30 cuts the rope 60. The cutting mechanism 30 includes a cutter 32 and a conveyor 31. The conveyor 31 is used to transfer the rope 60 to the cutter 32, and the cutter 32 is used to cut the rope 60.

[0039] In the above-mentioned rope cutting device, the tensioning mechanism 20 and the cutting mechanism 30 are both arranged on the frame 10. The tensioning mechanism 20 is used to pull the rope 60 to the cutting structure, and the cutting mechanism 30 cuts it. In addition, the tensioning mechanism 20 can adjust the tension of the rope 60 to make the tension of the rope 60 uniform, reduce the change of the tension of the rope 60 after entering the cutting mechanism 30, and thus ensure that the length of the rope 60 is consistent after being cut by the cutting mechanism 30.

[0040] Continue to see Figure 1, in some embodiments, the cord cutting device further includes at least one anti-twist member 22. The anti-twist members 22 are all arranged on the frame 10 and are configured below the tensioning mechanism 20. The anti-twist members 22 are provided with anti-twist holes for the cord 60 to pass through. The cord 60 in the placement turnover box is passed through the anti-twist holes. During the feeding process, it is ensured that one cord 60 passes through one anti-twist hole, avoiding the adjacent cords 60 from contacting, winding and twisting, which affects the product quality. In a feasible implementation, the number of anti-twist members 22 can be the same as the number of cords 60 to be separated, so that each cord can extend into one anti-twist member 22.

[0041] Exemplarily, the anti-twist member 22 can be an annular structure, thus having an annular hole. The cord 60 is drawn to the tensioning mechanism 20 after passing through the anti-twist hole of the anti-twist member 22 from the turnover box.

[0042] In some embodiments, the cord cutting device further includes a wire pressing roller group 40. The wire pressing roller group 40 is arranged on the frame 10 and is configured between the anti-twist member 22 and the tensioning mechanism 20. The wire pressing roller group 40 includes a first pressing roller 41 and a second pressing roller 42. There is a roller gap between the first pressing roller 41 and the second pressing roller 42. The roller gap is for the cord 60 to pass through. In this way, the cord 60 passes through the roller gap, and is squeezed by the first pressing roller 41 and the second pressing roller 42 to improve the straightness and reduce the probability of shaking, so that the cord 60 does not shake significantly left and right after moving to the tensioning wheel 21.

[0043] In some embodiments, the wire pressing roller group 40 includes a first pressing roller 41 and a second pressing roller 42. At least one of the first pressing roller 41 and the second pressing roller 42 is movable to adjust the width of the roller gap.

[0044] In a feasible implementation, the wire pressing roller group 40 is installed in the middle of the frame 10. The second pressing roller 42 can be used as a driving roller. The second pressing roller 42 is fixed on the frame 10 and can only rotate, while the first pressing roller 41 can move vertically up and down, which is convenient for the cord 60 to pass through and can prevent people from accidentally entering and causing safety accidents. In another feasible implementation, the first pressing roller 41 can be fixed as a driving roller, while the second pressing roller 42 moves up and down.

[0045] By moving the first pressing roller 41 or the second pressing roller 42, the distance between the first pressing roller 41 and the second pressing roller 42 can be adjusted, and then the size of the roller gap can be adjusted. On the one hand, it can adapt to cords 60 of various diameters, and on the other hand, the pressure on the cord 60 can be adjusted by adjusting the size of the roller gap.

[0046] In some embodiments, the cord cutting device further includes a detection switch 50. The detection switch 50 is disposed on the frame 10 and is used to detect the dropping distance of the cord 60 on the second side S2 of the tensioning pulley 21. After the cord 60 moves to the second side S2 of the tensioning pulley 21, it will partially drop under the action of gravity and then enter the cutting mechanism 30, and thus form a U shape in the middle part. The dropping distance of the cord 60 refers to the distance from the separation point of the cord 60 from the tensioning pulley 21 to the lowest point of the U shape.

[0047] Exemplarily, the detection switch 50 can be a photoelectric switch, an infrared sensor, etc. Generally, the position of the separation point of the cord 60 from the tensioning pulley 21 is fixed or fluctuates within a very small range. By detecting the position of the lowest point of the U shape by the detection switch 50, the dropping distance of the cord 60 can be determined. Exemplarily, a reflecting mirror 51 is further included. The reflecting mirror 51 is disposed on the frame 10 to facilitate observing the state of the cord 60 for adjustment.

[0048] Further, the roller motor 43 is connected to the driving roller. The driving roller can be rotated in a set direction by the roller motor 43. The detection switch 50 is connected to the roller motor 43, and the roller motor 43 can be controlled to stop by the detection switch 50. Optionally, the tensioning pulley 21 is driven by a tensioning pulley motor 214. In this way, when the detection switch 50 detects that the dropping distance of the cord 60 is abnormal, the roller motor 43 can be controlled to stop, which is convenient for maintenance and troubleshooting of abnormal faults.

[0049] In some embodiments, the cutting mechanism 30 further includes a limiting ring 33. The limiting ring 33 is disposed between the tensioning mechanism 20 and the conveying member 31 and is used for the cord 60 to pass through to limit the cord 60 and restrict the swaying of the cord 60. After the cord 60 passes through the limiting ring 33, its swaying is restricted by the limiting ring 33, thereby ensuring the stability of the cord 60 entering the cutter 32.

[0050] Further, the cutting mechanism 30 further includes at least one limiting component 34. The limiting component 34 is disposed between the limiting ring 33 and the conveying member 31 and is used to pass through the cord 60 and limit the cord 60 to restrict the lateral movement of the cord 60. The swaying of the cord 60 can be further restricted by the limiting component 34 to ensure its stability when entering the cutter 32, thereby improving the working efficiency and ensuring that the lengths of the cut cords 60 are consistent.

[0051] In a feasible implementation manner, the limiting component 34 includes a first limiting member and a second limiting member. A limiting interval for the cord 60 to pass through is formed between the first limiting member and the second limiting member. In this way, the first limiting member and the second limiting member respectively limit the displacement of the cord 60 in two lateral directions.

[0052] Further, in some embodiments, the position of the limiting interval corresponds to that of the limiting ring 33, so that the path of the cord 60 from the limiting ring 33 to the cutting knife 32 is a straight line. By corresponding the position of the limiting interval with that of the limiting ring 33, it is ensured that the cord 60 can enter the cutting knife 32 in a straight line when being sent thereto.

[0053] The corresponding position of the limiting interval and the limiting ring 33 means that the limiting interval is located on the central vertical line of the limiting ring 33. In this way, after passing through the limiting ring 33, the cord 60 extends into the limiting interval in a straight line exactly. In a feasible implementation manner, the cutting mechanism 30 includes a plurality of limiting intervals, and all the plurality of limiting intervals are located on the central vertical line of the limiting ring 33.

[0054] In some embodiments, the tensioning wheel 21 includes two relatively arranged clamping plates 211, a plurality of cross bars 212 arranged between the two clamping plates 211, and a rotating shaft 213 connecting the centers of the two clamping plates 211. The cross bars 212 are used to drive the cord 60 to move. The tensioning mechanism 20 further includes a tensioning wheel motor 214, and the tensioning wheel motor 214 is used to drive the rotating shaft 213 to rotate.

[0055] Exemplarily, the clamping plate 211 can be circular. The rotating shaft 213 is connected to the central positions of the two clamping plates 211. When the tensioning wheel motor 214 drives the rotation, the two clamping plates 211 rotate accordingly, thereby driving the cord 60 to move. Exemplarily, the cross bars 212 can be arranged around the rotating shaft 213 to contact the cord 60.

[0056] When using the above cord cutting device, first pass the cord 60 to be cut through the anti-twist member 22 to reduce the phenomenon of twisting. Control the first pressing roller 41 and the second pressing roller 42 to move relatively away from each other to increase the distance between the roller gaps. Place the cord 60 between the first pressing roller 41 and the second pressing roller 42, then pass the cord 60 around the tensioning wheel 21, and start the tensioning wheel motor 214 and the driving roller motor. Drive the driving roller and the tensioning wheel 21 to rotate by the motor, thereby pulling the cord 60 in the turnover box for feeding. At the same time, detect the dropping distance of the cord 60 through the detection switch 50. When the dropping distance is too large to trigger the condition, the roller motor 43 stops running. After adjustment and maintenance, start it again to ensure that the cord 60 is relatively stable in force. On the cutting mechanism 30, make the cord 60 pass through the limiting ring 33 and the limiting component 34 to ensure that the cord 60 will not shift left and right during the material transportation. Finally, the feeding member feeds the cord 60 into the cutting knife 32 to complete the cutting, that is, simultaneously cut a plurality of cords 60, and ensure that after the cords 60 are cut, their lengths can be made consistent in the non-loaded state.

[0057] The rope cutting device provided by the utility model drives a driving roller and a tensioning wheel 21 by a motor, thereby pulling the rope 60 in the turnover box for feeding. The rope 60 in the turnover box passes through an anti-twist ring to reduce the phenomenon of twisting. Through the driving of the pressing roller and the driving roller and the rolling treatment of the tensioning wheel 21, the phenomenon of uneven force caused by extrusion, knotting, etc. when the rope 60 is pulled up is solved, and the sag of the rope 60 is detected by a detection switch 50, so that the rope 60 after passing through the tensioning wheel 21 is more stable in force. After the rope 60 passes through the tensioning wheel 21, it enters the cutting knife 32 through the limit ring 33 and the limit component 34 on the device, that is, the simultaneous cutting of multiple ropes 60 is realized, and it is ensured that after the ropes 60 are cut, they can be of the same length in a non-loaded state. The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0058] The above-mentioned embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
