Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production machinery and equipment, mainly aims at the problem of cigarette machine coil paper supply, and specifically relates to a cigarette machine coil paper stabilization device and method. Background Art

[0002] In the cigarette production process, high-speed cigarette making machines such as ZJ116 are usually equipped with paper coil supply equipment. After the paper coil is supplied by the supply equipment, the double-width paper coil is cut on the cigarette making machine, so the accuracy of the paper coil position must be guaranteed. Since the cigarette making machine is fast and the paper coil is easy to break, the stability of the paper coil operation is the basis for the normal operation of the equipment. Since there is a long distance between the cigarette making machine and the paper coil supply equipment, the paper coil will vibrate and have position deviation during transportation. At the same time, affected by the aging of the paper coil supply equipment and the manufacturing accuracy of the paper coil, the end face of the paper coil will jump greatly during rotation, causing the paper coil to move back and forth horizontally during transportation, resulting in paper coil position deviation, uneven paper cutting, and even frequent paper breaks, seriously affecting the operation efficiency of the equipment.

The adjusting screw 34 passes through the threaded hole provided in the middle of the adjuster 33 and the through hole of the fixing plate 31, and the axial movement of the adjusting screw 34 is limited on the fixing plate 31 by the second retaining ring 37.

[0016] The second aspect of the present invention provides a method for stabilizing paper coils for a cigarette making machine, using the device for stabilizing paper coils for a cigarette making machine described in the first aspect of the present invention, comprising: the swing mechanism 1 is fixed at the end of the paper coil feeding device 52 to correct the lateral movement of the paper coil 51; the paper pressing mechanism 2 is arranged at the end of the paper coil conveying channel 4 to prevent the paper coil 51 from shaking and to perform preliminary correction on the position of the paper coil 51; the position adjustment mechanism 3 is provided with a spring to eliminate the screw pair movement during the adjustment process, and the locking screw locks the adjustment screw to prevent position adjustment errors caused by equipment vibration during operation; the swing mechanism 1, the paper pressing mechanism 2, and the position adjustment mechanism 3 jointly ensure the stability and position accuracy of the paper coil during the supply process, and can greatly reduce the problems of paper breakage, uneven paper cutting, and other faults.

[0017] Specifically, the working principle of the cigarette paper stabilizing device and the cigarette paper stabilizing method of the present invention are as follows: a guide bar 12 is fixed on both sides of the rocking plate 11, and the three form a paper winding channel. The waist hole provided on the guide bar 12 can adjust the width of the channel, wherein the cross section of the guide bar 12 is "L" shaped, and the guide bar 12 and the rocking plate 11 form a guide groove, which can effectively limit the paper edges of the two sides of the paper winding 51 in the guide groove. One end of the rocking plate 11 rotates on the bearing coaxially 15, and the "C"-shaped structure limit plate 16 limits the rotation of the rocking plate 11, so that the rocking plate 11 can continue to swing freely only within a certain range. The paper winding 51 runs from the far end of the rocking plate 11 to the center of the swing circle. If the paper winding 51 moves horizontally on the paper winding supply device, the paper winding 51 will drive the rocking plate 11 to swing. Since the arc length of the swing along the movement direction of the paper winding 51 gradually shortens, until the swing of the paper winding 51 at the center of the rocking plate 11 is close to zero, the correction of the horizontal movement of the paper winding is finally achieved.

[0018] The arc plate 21 appropriately presses the paper roll 51 into an arc shape, which can prevent the paper roll 51 from shaking during high-speed movement and enhance the stability of the paper roll 51. The stoppers 22 at both ends of the arc plate 21 slightly contact the two sides of the paper roll 51 to perform preliminary correction on the position of the paper roll 51. The screw rod 24 can rotate in the sleeve 25. The first clamping rings 28 at both ends of the sleeve 25 limit the axial movement of the screw rod 24. When the screw rod 24 is rotated, the screw rod 24 cannot move axially, and the adjusting rod 23 threadedly matched with the screw rod 24 will move axially. The screw 24 is rotated to adjust the lateral position of the arc plate 21, thereby adjusting the position of the paper coil 51; one end of the cylindrical pin 27 is fixed to the bracket 26, and the other end is placed in the opening groove of the adjusting rod 23, thereby preventing the adjusting rod 23 from rotating with the screw 24; one end of the bracket 26 is fixed to the frame of the cigarette making machine 53 by a screw, and the screw is loosened, and the bracket 26 can be rotated along the screw to change the distance between the paper pressing mechanism 2 and the paper coil 51, thereby adjusting the degree of action of the paper pressing mechanism 2 on the paper coil 51.

[0019] The paper roll 51 is placed in the guide groove 331 of the adjuster 33. The adjuster 33 is provided with two countersunk holes. Two round rods 32 are placed in the countersunk holes of the adjuster 33 to form a floating connection, so that the adjuster 33 can slide on the round rods 32. The second clamping ring 37 limits the axial movement of the adjusting screw 34 on the fixed plate 31. Since the adjusting screw 34 and the adjuster 33 form a spiral pair, the position of the adjuster 33 can be adjusted by rotating the adjusting screw 34, and then the position of the paper roll 51 can be adjusted to achieve the slitting width of the paper roll 51 by the downstream mechanism. The spring 35 is installed on the adjusting screw 34, and its two ends are respectively fitted with the fixed plate 31 and the adjuster 33. The elastic force of the spring 35 can make the adjuster 33 always under force, prevent the movement caused by the gap of the spiral pair, and enhance the accuracy of the adjuster 33; after the position is adjusted, the adjusting screw 34 is locked by applying radial force to the adjusting screw 34 through the locking screw 36 to prevent the vibration during the operation of the equipment from causing the adjusting screw 34 to rotate, resulting in the deviation of the position of the paper roll 51.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention discloses a paper coil stabilizing device for a cigarette making machine. The lateral movement of the paper coil is corrected by a swing mechanism. The paper pressing mechanism prevents the paper coil from shaking. At the same time, the position of the paper coil is preliminarily corrected. The position adjustment mechanism can enhance the accuracy and stability of the paper coil position adjustment. The device can ensure the stability and position accuracy of the paper coil during the supply process, greatly reduce the problems of paper breakage, uneven paper cutting and other faults, and improve the efficiency and reliability of the operation of the cigarette making machine equipment.

[0043] Specifically, the working principle of the cigarette paper stabilizing device and the cigarette paper stabilizing method of the present embodiment are as follows: a guide bar 12 is fixed on each side of the rocking plate 11, and the three form a paper coiling channel. The waist hole provided on the guide bar 12 can adjust the width of the channel, wherein the cross section of the guide bar 12 is "L" shaped, and the guide bar 12 and the rocking plate 11 form a guide groove, which can effectively limit the paper edges of the paper coil 51 on both sides in the guide groove. One end of the rocking plate 11 rotates on the bearing coaxially 15, and the "C"-shaped structure limit plate 16 limits the rotation of the rocking plate 11, so that the rocking plate 11 can continue to swing freely only within a certain range. The paper coil 51 runs from the far end of the rocking plate 11 to the center of the swing circle. If the paper coil 51 moves horizontally on the paper coil feeding device, the paper coil 51 will drive the rocking plate 11 to swing. Since the arc length of the swing along the movement direction of the paper coil 51 gradually shortens, until the swing of the paper coil 51 at the center of the rocking plate 11 is close to zero, the correction of the horizontal movement of the paper coil is finally achieved.

[0044] The arc plate 21 appropriately presses the paper roll 51 into an arc shape, which can prevent the paper roll 51 from shaking during high-speed movement and enhance the stability of the paper roll 51. The stoppers 22 at both ends of the arc plate 21 slightly contact the two sides of the paper roll 51 to perform preliminary correction on the position of the paper roll 51. The screw rod 24 can rotate in the sleeve 25. The first clamping rings 28 at both ends of the sleeve 25 limit the axial movement of the screw rod 24. When the screw rod 24 is rotated, the screw rod 24 cannot move axially, and the adjusting rod 23 threadedly matched with the screw rod 24 will move axially. The screw 24 is rotated to adjust the lateral position of the arc plate 21, thereby adjusting the position of the paper coil 51; one end of the cylindrical pin 27 is fixed to the bracket 26, and the other end is placed in the opening groove of the adjusting rod 23, thereby preventing the adjusting rod 23 from rotating with the screw 24; one end of the bracket 26 is fixed to the frame of the cigarette making machine 53 by a screw, and the screw is loosened, and the bracket 26 can be rotated along the screw to change the distance between the paper pressing mechanism 2 and the paper coil 51, thereby adjusting the degree of action of the paper pressing mechanism 2 on the paper coil 51.

[0045] The paper roll 51 is placed in the guide groove 331 of the adjuster 33. The adjuster 33 is provided with two countersunk holes. Two round rods 32 are placed in the countersunk holes of the adjuster 33 to form a floating connection, so that the adjuster 33 can slide on the round rods 32.
