In actual production, the transparent paper packaging machine undertakes the rewinding work of transparent paper of different sizes. For transparent paper of different sizes, its axial size needs to be frequently moved according to the size of the cigarette rods so that the transparent paper and the cigarette rods can be aligned. In the prior art, the axial position of the transparent paper is usually adjusted manually, and each adjustment depends entirely on the feel and experience of the operator, resulting in the need for repeated adjustments each time the size of the transparent paper is changed. Not only is the accuracy of the transparent paper size difficult to guarantee, but the adjustment efficiency is also low, wasting a lot of work time. Summary of the invention

[0009] The positioning device for the transparent paper roll mounts the transparent paper roll on the mounting shaft. The current position of the transparent paper roll is read by the pointer assembly abutting against the end face of the transparent paper roll. The driving mechanism can drive the mounting shaft to move along its axial direction according to the current position of the transparent paper roll and the preset target position, so as to drive the transparent paper roll to move to the preset target position, thereby realizing the positioning of the transparent paper roll. The positioning device for the transparent paper roll can achieve rapid position adjustment for transparent paper rolls of different sizes, avoid repeatedly adjusting the axial position of the transparent paper roll by hand feeling, reduce the installation and debugging time of the transparent paper roll, ensure the adjustment accuracy, and improve the operation efficiency.

[0066] During the production process, cigarette products such as cigarette rods need to be wrapped with a layer of transparent paper on the outside to play a role in sealing and moisture-proofing. In actual production, the transparent paper packaging machine undertakes the rewinding work of transparent paper of different sizes. For transparent paper of different sizes, its axial size needs to be frequently moved according to the size of the cigarette rods so that the transparent paper and the cigarette rods can be aligned. In the prior art, the axial position of the transparent paper is usually adjusted manually, and each adjustment depends entirely on the feel and experience of the operator, resulting in the need for repeated adjustments each time the size of the transparent paper is changed. Not only is the accuracy of the transparent paper size difficult to guarantee, but the adjustment efficiency is also low, wasting a lot of work time.

[0067] In order to solve the above problems, Figure 1 As shown, this embodiment provides a transparent paper roll positioning device, including a frame 1, a pointer assembly 3 and a driving mechanism 4. The frame 1 is provided with a scale 2, the scale 2 is arranged in a horizontal plane, and the scale 2 is arranged along a first direction ( Figure 1 The pointer assembly 3 is movably arranged on the frame 1 along the first direction, and the pointer assembly 3 can be locked with the frame 1, and the position of the pointer assembly 3 can be read through the scale 2; the driving mechanism 4 is installed on the frame 1, and the output end of the driving mechanism 4 is transmission-connected with the mounting shaft 5, the mounting shaft 5 extends in parallel with the first direction, and the transparent paper roll 100 is installed on the mounting shaft 5. The driving mechanism 4 can drive the mounting shaft 5 to move along its axial direction to drive the transparent paper roll 100 to move, and the pointer assembly 3 can abut against the end face of the transparent paper roll 100 to read the position of the transparent paper roll 100.

[0068] The transparent paper roll positioning device installs the transparent paper roll 100 on the mounting shaft 5, and the pointer assembly 3 abuts against the end surface of the transparent paper roll 100 to read the current position of the transparent paper roll 100. The driving mechanism 4 can drive the mounting shaft 5 to move along its axial direction according to the current position of the transparent paper roll 100 and the preset target position, so as to drive the transparent paper roll 100 to move to the preset target position, thereby realizing the positioning of the transparent paper roll 100. The transparent paper roll positioning device can realize rapid position adjustment for transparent paper rolls 100 of different sizes, avoid repeatedly adjusting the axial position of the transparent paper roll 100 by hand, reduce the installation and debugging time of the transparent paper roll 100, ensure the adjustment accuracy, and improve the working efficiency.

[0069] It should be noted that the preset target position of the transparent paper roll 100 is determined according to the position of the cigarette rod. When the transparent paper roll 100 reaches the preset target position, the center line of the transparent paper roll 100 and the center line of the cigarette rod are in a straight line.

[0070] In this embodiment, the middle position of the scale 2 is a zero scale line, one side of the zero scale line is a positive value, and the other side is a negative value. The scale 2 is used to facilitate reading the position of the transparent paper roll 100.

[0071] As Figure 1 and Figure 2 shown, a guide rail 11 is provided on the frame 1 along a first direction. The pointer assembly 3 is slidably arranged on the guide rail 11 and can be locked on the guide rail 11 after the pointer assembly 3 is adjusted in place. The arrangement of the guide rail 11 can play a guiding role in the movement of the pointer assembly 3, enabling the pointer assembly 3 to move along the first direction and preventing the movement of the pointer assembly 3 from being skewed.

[0072] As Figure 2 and Figure 3 shown, the pointer assembly 3 includes a slide base 31, a measuring pointer 32, and a locking assembly 33. The slide base 31 is slidably arranged on the guide rail 11 along the first direction; the measuring pointer 32 is installed on the slide base 31, and the measuring pointer 32 can be folded and unfolded. When the measuring pointer 32 is unfolded, it can abut against the end face of the transparent paper roll 100. When the measuring pointer 32 is folded, it is located below the transparent paper roll 100; the locking assembly 33 is arranged on the slide base 31 and is used to lock or unlock the slide base 31 with the frame 1. The slide base 31 facilitates the installation of the measuring pointer 32 and the locking assembly 33. By moving the slide base 31 along the first direction, the measuring pointer 32 and the locking assembly 33 are driven to move; the measuring pointer 32 can abut against the end face of the transparent paper roll 100 through unfolding, facilitating reading; through folding, the measuring pointer 32 can be located below the transparent paper roll 100 to avoid interfering with the movement of the transparent paper roll 100; the locking assembly 33 can lock or unlock the slide base 31 with the frame 1, facilitating accurate reading during locking and adjusting the position of the pointer assembly 3 during sliding.

[0073] In this embodiment, as Figure 3 shown, the locking assembly 33 includes a locking knob. A first threaded hole 311 is provided on the slide base 31. The locking knob is threadedly connected in the first threaded hole 311 and can abut against the frame 1 or disengage from the frame 1 to lock the slide base 31 with the frame 1; or unlock the slide base 31 from the frame 1. When the locking knob abuts against the frame 1, the slide base 31 is locked with the frame 1; when the locking knob disengages from the frame 1, the slide base 31 is unlocked from the frame 1. The structure of this locking assembly 33 is simple, facilitating the switching between locking and unlocking, and the operation is relatively convenient.

[0074] Continue to refer to Figure 3, the measuring pointer 32 includes a mounting base 321. The mounting base 321 includes a fixing part 3211 and a rotating part 3212. The fixing part 3211 is mounted on the sliding base 31. One end of the rotating part 3212 is hinged to the fixing part 3211, and the other end of the rotating part 3212 is mounted with an indicating needle 322. In this embodiment, one end of the rotating part 3212 is hinged to the fixing part 3211 through a pin shaft 3213. By rotating the rotating part 3212 relative to the fixing part 3211, the unfolding and folding of the indicating needle 322 are realized. The structure of the measuring pointer 32 is relatively simple, which is convenient for realizing the state switching of the indicating needle 322.

[0075] Preferably, the indicating needle 322 is detachably connected to the rotating part 3212, which is convenient for the disassembly and replacement of the indicating needle 322. In this embodiment, a first fixing hole is provided on the rotating part 3212, and a second fixing hole is provided on the indicating needle 322. The rotating part 3212 and the indicating needle 322 are connected by a fixing member passing through the first fixing hole and the second fixing hole. In other embodiments, the detachable connection between the indicating needle 322 and the rotating part 3212 is not limited to the above method, and can also be plugging, clamping, etc.

[0076] Optionally, the positioning device of the transparent paper roll further includes a stop and locking assembly 6. Two sets of stop and locking assemblies 6 are detachably mounted on the mounting shaft 5 and are located at both ends of the transparent paper roll 100 to clamp the transparent paper roll 100. The setting of the stop and locking assembly 6 can clamp the transparent paper roll 100, perform axial locking and positioning on the transparent paper roll 100, and prevent the transparent paper roll 100 from shifting during operation. It should be noted that the stop and locking assembly 6 only limits the axial position of the transparent paper roll 100, and the transparent paper roll 100 can release the transparent paper under the action of tension to package the cigarette rod.

[0077] As Figure 1 shown, the stop and locking assembly 6 includes a mounting retaining ring 61 and a locking member 62. The mounting retaining ring 61 is sleeved on the mounting shaft 5 and can abut against the end face of the transparent paper roll 100. A second threaded hole (not shown in the figure) is provided on the mounting retaining ring 61; the locking member 62 is threadedly connected to the second threaded hole, and the locking member 62 can abut against the circumferential surface of the mounting shaft 5 or disengage from the end face of the mounting shaft 5. The stop and locking assembly 6 stops the transparent paper roll 100 through the mounting retaining ring 61. The locking member 62 is threadedly connected to the second threaded hole of the mounting retaining ring 61. The locking member 62 abuts against or separates from the circumferential surface of the mounting shaft 5 to lock or unlock the mounting retaining ring 61. The stop and locking assembly 6 not only has a simple structure, but also is convenient for the state switching between locking and unlocking, and is relatively convenient to use. In this embodiment, the locking member 62 is an internal hexagonal screw, and the internal hexagonal screw can be tightened and loosened by a tool.

[0078] Preferably, the circumferential direction of the mounting retaining ring 61 is locked by a plurality of locking members 62, so that the circumferential force on the mounting retaining ring 61 is relatively uniform. In this embodiment, three second threaded holes are provided in the circumferential direction of the mounting retaining ring 61, and the three second threaded holes are equidistantly arranged along the circumferential direction of the mounting retaining ring 61. A locking member 62 is threadedly connected to each second threaded hole. In other embodiments, two, four, five or more second threaded holes may be provided in the circumferential direction of the mounting retaining ring 61, and the second threaded holes are equidistantly arranged along the circumferential direction of the mounting retaining ring 61. A locking member 62 is threadedly connected to each second threaded hole.

[0079] In this embodiment, as Figure 1 shown, the positioning device for the transparent paper roll further includes a guide sleeve 7. The guide sleeve 7 is supported on the machine frame 1 (not shown in the figure). The mounting shaft 5 is sleeved in the guide sleeve 7 and can move axially along the guide sleeve 7. The guide sleeve 7 is provided with a guide hole 71 in its axial direction; the driving mechanism 4 includes a motor. In this embodiment, the motor is a servo motor with high adjustment accuracy. A lead screw (not shown in the figure) is provided at the output end of the motor. The lead screw can extend into the guide sleeve 7 from any end of the guide sleeve 7. A slider (not shown in the figure) threadedly connected to the lead screw is sleeved on the lead screw. The slider passes through the guide hole 71 and is connected to the mounting shaft 5. The lead screw is connected to the mounting shaft 5 through the slider sleeved on it. When the driving mechanism 4 drives the lead screw to rotate, the slider moves linearly under the guiding action of the guide hole 71 to drive the mounting shaft 5 to move axially along the guide sleeve 7, preventing the mounting shaft 5 from rotating, thereby realizing the adjustment of the axial position of the transparent paper roll 100. The above connection and transmission mode between the driving mechanism 4 and the mounting shaft 5 has a simple structure and is easy to implement. In other embodiments, the adjustment of the axial position of the mounting shaft 5 is not limited to the above method, and the driving mechanism 4 can also drive the mounting shaft 5 to perform linear operation, as long as the adjustment of the axial position of the mounting shaft 5 can be realized.

[0080] Optionally, the driving mechanism 4 is electrically connected to the control device. The control device is connected to a screen, and input options are provided on the screen. The operator inputs the moving distance of the transparent paper roll 100 to drive the driving mechanism 4 to drive the transparent paper roll 100 to move a corresponding distance, so that the transparent paper roll 100 moves to a preset target position, avoiding manual adjustment and having a higher adjustment accuracy.

[0081] The positioning device for the transparent paper roll can quickly adjust to the required position for transparent paper rolls of different sizes, avoiding repeatedly adjusting the axial position of the transparent paper roll 100 by hand feeling, reducing the installation and debugging time of the transparent paper, and improving the operation efficiency; driven by the servo motor of the driving mechanism 4, the adjustment accuracy is high, and the operator only needs to input parameters, avoiding manual adjustment.

[0082] This embodiment also provides a method for using a positioning device for a transparent paper roll, which is applied to the above-mentioned positioning device for a transparent paper roll. The control method of the positioning device for a transparent paper roll includes the following steps:

[0083] Install the transparent paper roll 100 on the mounting shaft 5;

[0084] Make the pointer assembly 3 abut against the end face of the transparent paper roll 100 to read the current position of the transparent paper roll 100;

[0085] The driving mechanism 4 drives the mounting shaft 5 to move according to the current position of the transparent paper roll 100 and the preset target position, so as to drive the transparent paper roll 100 to move to the preset target position.

[0086] During use, install the transparent paper roll 100 on the mounting shaft 5, make the pointer assembly 3 abut against the end face of the transparent paper roll 100 to read the current position of the transparent paper roll 100, and the driving mechanism 4 drives the mounting shaft 5 to move according to the current position of the transparent paper roll 100 and the preset target position, so as to drive the transparent paper roll 100 to move to the preset target position, completing the positioning of the transparent paper roll 100. The above-mentioned use method can achieve rapid position adjustment for transparent paper rolls 100 of different sizes, reduce the installation and debugging time, improve the operation efficiency, and ensure the adjustment accuracy.

[0087] Optionally, after installing the transparent paper roll 100 on the mounting shaft 5 and before reading the current position of the transparent paper roll 100 through the pointer assembly 3, the following steps are further included:

[0088] Move the pointer assembly 3 to the zero scale line of the scale 2;

[0089] Move the transparent paper roll 100 so that the end face of the transparent paper roll 100 abuts against the pointer assembly 3;

[0090] Zero the driving mechanism 4.

[0091] The above steps achieve the zeroing operation of the pointer assembly 3 and the driving mechanism 4, facilitating the subsequent adjustment of the moving positions of the pointer assembly 3 and the driving mechanism 4.

[0092] Specifically, there are two cases when using:

[0093] Case 1:

[0094] First, as Figure 1 shown, loosen the locking member 62 on the mounting retaining ring 61 on the left side of the transparent paper roll 100, remove the mounting retaining ring 61 to the left, remove the old transparent paper roll 100, and install a new transparent paper roll 100;

[0095] Then, move the position of the transparent paper roll 100. Depending on the situation, loosen the locking member 62 on the mounting retaining ring 61 on the right side of the transparent paper roll 100 (if the right mounting retaining ring 61 affects the position adjustment of the transparent paper roll 100, loosen the right locking member 62), lock the locking members 62 on both the left and right sides of the transparent paper roll 100, and axially fix the transparent paper roll 100 on the mounting shaft 5;

[0096] After that, move the pointer assembly 3 so that the indicating needle 322 abuts against the end face of the transparent paper roll 100. At this time, tighten the locking knob to fix the position of the indicating needle 322, and read the current position of the pointer assembly 3, which is the current position of the transparent paper roll 100;

[0097] After that, loosen the locking knob, move the pointer assembly 3 to the end of the guide rail 11, and fold down the measuring pointer 32 to avoid interference between the indicating needle 322 and the transparent paper roll 100;

[0098] After that, the driving mechanism 4 is started. The driving mechanism 4 drives the mounting shaft 5 to move, and drives the transparent paper roll 100 to move left and right. When it moves to the preset target position, stop, and then the machine can be started for production.

[0099] Case 2:
