[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] like Figure 1-4 As shown, a cross-over water cutting knife comprises a main square tube 1 and a cross-over trolley 2. A horizontal track hole is opened on the side of the main square tube 1. The cross-over trolley 2 is provided with an upper roller 3 and a lower roller 4. The upper roller 3 and the lower roller 4 are respectively adapted to roll with the upper groove wall and the lower groove wall of the horizontal track hole; a driving sprocket 5 and a driven sprocket 6 are respectively rotatably provided at both ends of the main square tube 1. The driving sprocket 5 is connected to a driving motor 7 in transmission connection. The left end of the cross-over trolley 2 is connected to one end of a chain 24, and the right end of the cross-over trolley 2 is connected to the other end of the chain 24. The chain 24 is sleeved on the driving sprocket 5 and the driven sprocket 6; a vertical hard tube 8 is provided on the outer side of the cross-over trolley 2 away from the main square tube 1, and a high-pressure water needle 9 is connected to the lower end of the vertical hard tube 8. The upper end of the vertical hard pipe 8 is connected to one end of a water hose 10, and the water hose 10 enters the main square tube 1 from the cross-cart 2. After a section of the water hose 10 is reserved in the main square tube 1, the other end is connected to a water source connecting pipe 11. The water source connecting pipe 11 passes through the lower end surface of the main square tube 1, and the inner end of the water source connecting pipe 11 is connected to the water hose 10, and the outer end of the water source connecting pipe 11 is connected to a water source; a drag chain 12 is arranged in the main square tube 1, one end of the drag chain 12 is fixed to the inner bottom of the main square tube 1, and the other end of the drag chain 12 is fixed to the cross-cart 2, and the extension direction of the non-turning part of the drag chain 12 is consistent with the length direction of the main square tube 1, and the part of the water hose 10 reserved in the main square tube 1 is inserted in the drag chain 12.

[0022] Three position detectors 13 are arranged on the outside of the main square tube 1 above the moving path across the trolley 2. The three position detectors 13 are respectively set at the parking maintenance position, the operation start position and the operation end position on the moving path through position detector guide rails (the position detectors can slide and lock on the position detector guide rails to facilitate fine-tuning of the actual setting position).

[0023] Working principle:

[0024] Before the equipment is operated, the straddle trolley 2 is located in the parking maintenance position, and the corresponding position detector 13 is used to confirm whether the straddle trolley 2 is currently parked in this position. After confirmation, the equipment starts to run, and the driving motor 7 controls the active sprocket 5 to rotate, and the chain 24 pulls the straddle trolley 2 from right to left. When the straddle trolley 2 moves to the starting position of the operation, the corresponding position detector 13 detects the straddle trolley 2, and the water source supplies water to the water source connecting pipe 11. The water reaches the high-pressure water needle 9 through the water supply hose 10 and the vertical hard pipe 8. The cutting operation is completed with the continuous movement of the straddle trolley 2. When the straddle trolley 2 reaches the end position of the operation, the corresponding position detector 13 detects the straddle trolley 2, the water supply stops, and the driving motor 7 reverses to reset the straddle trolley 2.

[0025] During operation, the water delivery hose 10 moves back and forth with the drag chain 12, and no external structure needs to be added for retraction and extension, thus saving space occupied by the equipment.

[0026] Reinforcement ribs 14 are provided at the inner upper end and the lower end of the main body square tube 1 away from the horizontal track hole, thereby enhancing the overall strength of the main body square tube 1 .

[0027] The non-turning part of the drag chain 12 includes an upper drag chain and a lower drag chain; a plurality of drag chain brackets 15 are arranged at intervals on the side wall of the main square tube 1 away from the horizontal track hole. The plurality of drag chain brackets 15 are horizontally collinear and the connecting line is located below the upper drag chain. The drag chain brackets 15 are intended to prevent the upper drag chain from falling off and ensure the normal operation of the equipment. In addition, the drag chain brackets 15 are arranged inside the main square tube 1 close to the power side to ensure that the cross-car 2 can smoothly reach the end of the power side.

[0028] An L-shaped baffle 16 is provided at the bottom of the inner side of the main square tube 1 below the lower drag chain and on one side thereof facing the horizontal track hole to prevent the drag chain 12 from detaching from the main square tube 1 during the operation of the equipment, thereby ensuring the normal operation of the equipment.

[0029] A shield 17 is provided on the outside of the main square tube 1 on one side of the horizontal track hole. The shield 17 completely covers the moving space across the trolley 2 and has a horizontal slot for the vertical hard tube 8 to pass freely on the lower end surface, which plays a protective role without affecting the operation of the equipment and also makes the equipment look more beautiful. A shield is also provided on the outside of the drive motor.

[0030] The right end of the cross-carriage 2 is connected to the chain 24 through a chain tension adjustment mechanism; the chain tension adjustment mechanism includes a middle brace 18, which is provided with an internal thread, and the two ends of the middle brace 18 are respectively screwed with adjustment screws 19, one of which is connected to the cross-carriage 2, and the other is connected to the chain 24; each adjustment screw 19 is provided with an adjustment nut 20 on the outer side of the middle brace 18, and the adjustment nut 20 is tightened on the end of the middle brace 18. After the equipment has been used for a period of time, the chain 24 will become loose. At this time, it is only necessary to loosen the adjustment nut 20, rotate the middle brace 18 to re-tighten the chain 24, and reset the adjustment nut 20 after tightening to ensure that the adjustment screw 19 is tightened.

[0031] The portion of the water hose 10 located at the cross-cart 2 is installed on the cross-cart 2 through a fixed pipe clamp 21, which enhances the stability of the connection between the water hose 10 and the vertical hard pipe 8 and ensures effective water supply during the operation.

[0032] The first three chain links at the end where the drag chain 12 is connected to the cross trolley 2 are installed in reverse order to eliminate the disturbance of the drag chain 12 and prevent the drag chain 12 from swinging down.

[0033] A detection gear 22 is provided at the end of the axle of the driving sprocket 5, and a counting detector 23 is provided below the detection gear 22. The detection gear 22 rotates synchronously with the driving sprocket 5, and the counting detector 23 records the rotation of the detection gear 22, thereby calculating the moving distance across the trolley 2, thereby determining the width of the paper web and ensuring the accuracy of the operation.

[0034] The present invention provides a cross-cutting water knife, which adopts a motor as a new power source and controls a chain to drive a cross-cart and a high-pressure water needle fixed on the cross-cart to move. A water supply hose for supplying water to the high-pressure water needle is inserted into the drag chain to fix the movement trajectory and is coiled in the main square tube of the equipment, thereby saving the overall space occupied by the equipment and reducing the production cost.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
