Description

Technical Field

[0001] The present application relates to the field of rapid printing technology, and in particular to an automatic rapid printing device and method for cigarette box packaging paper. Background Art

[0002] Cigarette box wrapping paper is a paper box used to package cigarettes. It has various styles. Before the paper box is processed, cigarette logos and tobacco components need to be printed on the cigarette box wrapping paper. Cigarette boxes are generally produced in large quantities, so fast printing equipment is needed.

[0003] In the related technology, a Chinese invention application with publication number CN115649907A discloses an automatic rapid printing device for cigarette box packaging paper and a method thereof, including a stratification mechanism, a blocking mechanism, a knocking mechanism, a flattening mechanism and a straightening mechanism, wherein the stratification mechanism, the blocking mechanism and the knocking mechanism ensure that the number of packaging papers entering the flattening mechanism at a single time is a single sheet, the flattening mechanism flattens the cigarette box packaging paper that may be bent, and then the straightening mechanism adjusts the position, and finally enters the printing place for printing.

[0004] For the above-mentioned related technologies, when placing the cigarette box wrapping paper, it is necessary to adjust the stratification mechanism and the blocking mechanism first, and the cigarette box wrapping paper can enter the flattening mechanism only after the knocking mechanism knocks and vibrates the stratification mechanism. After the flattening is completed, the cigarette box wrapping paper enters the straightening mechanism. From the initial placement of the cigarette box wrapping paper to the final straightening, the time required is relatively long, so improvements are made to this. Summary of the invention

[0005] In order to improve the printing efficiency of cigarette box packaging paper, the present application provides an automatic and fast printing device for cigarette box packaging paper.

[0006] The present application provides an automatic rapid printing device for cigarette box packaging paper, which adopts the following technical solution:

[0007] An automatic rapid printing device for cigarette box packaging paper comprises a mounting frame, a rotating rod is rotatably arranged on the mounting frame along the width direction of the mounting frame, a first swing rod, a second swing rod, a third swing rod and a sleeve are arranged on the rotating rod, the sleeve is fixedly sleeved on the rotating rod, the sleeve and the first swing rod are arranged at intervals, the second swing rod and the third swing rod are symmetrical with the inner symmetry center of the sleeve and are vertically arranged on the outer peripheral wall of the sleeve, and a driving component for driving the first swing rod to swing back and forth in an arc with the rotating rod as the center is arranged on the mounting frame;

[0008] A first movable rod is rotatably provided at one end of the second swing rod away from the sleeve, the angle between the second swing rod and the first movable rod opens downward, a first horizontal rod is rotatably provided at one end of the first movable rod away from the second swing rod, a first limit block for enabling the first horizontal rod to move only horizontally is provided on the mounting frame, and an adsorption mechanism for adsorbing a single piece of packaging paper and adjusting its position to transport it to a printing place is provided at one end of the first horizontal rod away from the first movable rod;

[0009] A second movable rod is rotatably provided at one end of the third swing rod away from the sleeve, the angle between the third swing rod and the second movable rod is open upward, a second horizontal rod is rotatably provided at one end of the second movable rod away from the third swing rod, a second limit block for allowing the second horizontal rod to move only horizontally is provided on the mounting frame, and a paper supply assembly for providing packaging paper to the adsorption mechanism is provided at one end of the second horizontal rod away from the second movable rod.

[0010] By adopting the above technical scheme, the adsorption mechanism in the present application can adsorb a single piece of packaging paper. Compared with taking out a single piece of packaging paper from the top or bottom of the packaging paper pile, the disturbance to the packaging paper pile is reduced, which can effectively reduce printing errors caused by driving other packaging papers when taking paper; the adsorption mechanism can also adjust the position of the packaging paper when the adsorption mechanism transports the single piece of packaging paper to the printing place, thereby improving the quality of printing on the packaging paper, and the paper supply assembly can continuously provide packaging paper to the adsorption mechanism; the driving assembly in the present application can drive the first swing rod to swing in an arc with the rotating rod as the center, thereby driving the second swing rod and the third swing rod on the first swing rod to swing in an arc in the opposite direction synchronously, under the action of the first movable rod, the first horizontal rod and the first limit block, the adsorption mechanism performs horizontal movement, and under the action of the second movable rod, the second horizontal rod and the second limit block, the paper supply assembly performs horizontal movement opposite to the adsorption mechanism, thereby realizing the relative movement between the paper supply assembly and the adsorption mechanism. The relative movement between the paper supply assembly and the adsorption mechanism can generate slight friction between the adsorbed single piece of packaging paper and the lower layer of packaging paper when the adsorption mechanism adsorbs a single piece of packaging paper, thereby avoiding possible adhesion between the packaging papers and further ensuring that the adsorption mechanism adsorbs a single piece of packaging paper at a time; compared with the comparative document, the adsorption mechanism in the present application can realize that there is no need to make excessive adjustments to the packaging paper pile when placing the packaging paper, and the knocking assembly, flattening mechanism and straightening mechanism in the prior art are on the same straight line, which prolongs the path and time required to transport the packaging paper to the printing place. Since the paper is relatively soft, if the prior art speeds up the operation speed of the equipment, the flattening mechanism and the straightening mechanism are likely to damage the paper. The present application uses adsorption to transport the packaging paper, which reduces the loss of paper while increasing the operating speed of the driving assembly and the adsorption mechanism according to actual needs to further improve the efficiency of printing the packaging paper.

[0011] Optionally, the driving assembly includes a first cam, a connecting rod and a first driving motor, the first driving motor is fixedly disposed on the mounting frame, the connecting rod is rotatably disposed on the mounting frame, and one end of the connecting rod is coaxially connected to the output of the first driving motor, the first cam is fixedly connected to an end of the connecting rod away from the first driving motor, the side wall of the first cam along the thickness direction is slidingly connected to the first rocker arm, and when the first cam rotates, it can drive the first rocker arm to swing back and forth in an arc with the rotating rod as the center.

[0012] By adopting the above technical solution, the first drive motor is started, and the first drive motor drives the first cam on the connecting rod to rotate. When the first cam rotates, it can drive the first swing rod to swing in an arc with the rotating rod as the center. When the first swing rod swings, it can drive the second swing rod and the third swing rod to swing in an arc in opposite directions synchronously, thereby realizing the horizontal opposite movement of the adsorption mechanism and the paper supply assembly through the first horizontal rod and the second horizontal rod.

[0013] Optionally, the adsorption mechanism includes a moving box, an air pump, an air suction pipe, a negative pressure head, a moving component and an adjustment component. The moving box is slidably set on the mounting frame, and the moving box is connected to the first horizontal rod. The air suction pump, the air suction pipe and the negative pressure head are all arranged in the moving box. The moving box and the mounting frame are provided with adsorption ports for the negative pressure head to extend out. One end of the air suction pipe is connected to the air pump, and the other end is connected to the negative pressure head. The moving component can make the negative pressure head extend from the adsorption port, and the adjustment component can adjust the position of a single piece of packaging paper while transporting the single piece of packaging paper.

[0014] By adopting the above technical solution, the vacuum pump is started, and the vacuum pump generates negative pressure on the surface where the negative pressure head contacts the packaging paper through the vacuum pipe, thereby adsorbing the packaging paper, and the moving component can move the negative pressure head up and down, so that when the adsorption mechanism and the paper supply component perform opposite movements, the moving component can transfer the packaging paper from the paper supply component to the printing position, and the adjustment component can adjust the position of the packaging paper during the transfer of the packaging paper, thereby facilitating the printing of the packaging paper, and because the adsorption mechanism and the paper supply component perform opposite movements, when the negative pressure head adsorbs the packaging paper, the adsorbed packaging paper will generate slight friction with the lower packaging paper, thereby avoiding possible adhesion between the packaging papers, and further ensuring that the adsorption mechanism adsorbs a single piece of packaging paper at a time.

[0015] Optionally, the moving assembly includes a second cam, a pushing rod and a limiting rod, a fixed bin and a moving bin are provided in the moving box, the vacuum pump is provided in the fixed bin, the negative pressure head is lifted and arranged in the moving bin, the fixed bin is provided above the moving bin, the second cam is provided on the rotating rod, the pushing rod is horizontally movable on the mounting frame, one end of the pushing rod away from the rotating rod passes through the side wall of the moving box and is connected to the side wall of the moving bin, and the limiting rod is provided with two groups, and the two groups of limiting rods are respectively perpendicular to the negative pressure The moving direction of the head is set on the side wall of the negative pressure head, and a vertical groove for the movement of the limit rod is opened on the side wall of the mobile bin. An arc groove begins to be provided on the side wall of the mobile box, and the end of the limit rod away from the negative pressure head is set in the vertical groove and the arc groove, and the arc opening of the arc groove faces downward. When the limit rod is located at one end of the arc groove close to the push rod, the negative pressure head absorbs the packaging paper in the paper supply assembly, and when the limit rod is located at one end of the arc groove away from the push rod, the negative pressure head places the absorbed packaging paper at the printing position.

[0016] By adopting the above technical solution, when the rotating rod rotates, it drives the second protrusion to rotate, thereby driving the mobile bin at the end of the push rod to move. When the mobile bin moves, since the end of the limit rod away from the negative pressure head is arranged in the vertical groove and the arc groove, the limit rod will move along the shape of the arc groove, thereby realizing the same moving trajectory of the negative pressure head, thereby realizing the negative pressure head is lifted and lowered in the mobile bin, and while the negative pressure head moves in the mobile bin, the mobile box is also moving in the same direction. When the mobile box moves to above the printing place, the mobile bin just moves to above the position where the packaging paper is placed at the printing place. The synchronous movement of the mobile box and the mobile bin can further reduce the time required to transfer the packaging paper from the paper supply assembly to the printing place, thereby further improving the printing efficiency of the packaging paper.

[0020] By adopting the above technical solution, when the mobile bin drives the mobile block to move, since the first threaded rod is rotatably installed on both sides of the mobile bin, and the first threaded rod and the mobile block are threadedly connected, when the mobile block moves, the first threaded rod rotates around itself as the axis, and since the first clamping block is threadedly connected between the first threaded rod, and the first clamping block is slidably installed on the first limit strip on the inner wall of the mobile box through the first limit groove, when the first threaded rod rotates, it can drive the first clamping plate on the first clamping block to move, thereby realizing the adjustment of the lateral position of the packaging paper.

[0021] Optionally, the longitudinal adjustment assembly includes a second clamping block, a second threaded rod, a second clamping plate, a driving bevel gear and a driven bevel gear.

The second clamping block is slidably arranged on the second limiting strip through the second limiting groove, and the second clamping plate is arranged perpendicular to the second clamping plate on the side of the second clamping block away from the vacuum pump.

[0022] By adopting the above technical solution, when the first threaded rod rotates, the active bevel gear and the driven bevel gear are meshed with each other, so the first threaded rod can drive the second threaded rod to rotate, and since the second clamping block and the second threaded rod are threadedly connected, the second clamping block is slidably set on the second limit strip through the second limit groove, so the second clamping plate on the second clamping block can be driven to move, thereby adjusting the longitudinal position of the packaging paper.

Under the support of the elastic member, the upper surface height of the topmost layer of wrapping paper will be slightly higher than the upper surface of the paper storage box. The support column can provide stability for the elastic member and reduce the deformation of the elastic member.

[0025] Optionally, a printing assembly is also provided on the mounting frame, and the printing assembly includes a conveyor belt, a leveling roller, a printing roller and a second driving motor.

Since the driving gear of the printing roller and the driven gear on the flattening roller are meshed with each other, the flattening roller can be driven to rotate synchronously in the opposite direction, thereby realizing the printing of the packaging paper.

The relative movement between the paper supply assembly and the adsorption mechanism can generate slight friction between the adsorbed single wrapping paper and the lower wrapping paper when the adsorption mechanism adsorbs a single wrapping paper, thereby avoiding possible adhesion between the wrapping papers, and further ensuring that the adsorption mechanism adsorbs a single wrapping paper at a time;

[0035] 2. The adsorption mechanism can realize that when placing the packaging paper, there is no need to make excessive adjustments to the packaging paper pile, and the knocking assembly, flattening mechanism and straightening mechanism in the prior art are in the same straight line, which prolongs the path and time required for transporting the packaging paper to the printing place.

The present application adopts an adsorption method to transport the packaging paper, which reduces the loss of the paper and can increase the operating speed of the driving assembly and the adsorption mechanism according to actual needs, so as to further improve the efficiency of printing the packaging paper;

[0036] 3. The transverse adjustment component and the longitudinal adjustment component can adjust the longitudinal and transverse positions of the packaging paper when the negative pressure head transfers the packaging paper, thereby facilitating the printing of the packaging paper and improving the printing quality of the packaging paper.

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-7 This application is described in further detail.

[0047] The present application embodiment discloses an automatic rapid printing device for cigarette box packaging paper. Figure 1 , Figure 2 and Figure 3 The automatic rapid printing equipment for cigarette box packaging paper includes a mounting frame 1, on which a rotating rod 11 is rotatably mounted along the width direction of the mounting frame 1, on which a first swing rod 111, a second swing rod 112, a third swing rod 113 and a sleeve 114 are mounted, the sleeve 114 is fixedly sleeved and welded on the rotating rod 11, the sleeve 114 and the first swing rod 111 are installed at intervals, the second swing rod 112 and the third swing rod 113 are symmetrically mounted with the inner symmetry center of the sleeve 114 and vertically welded on the outer peripheral wall of the sleeve 114, and a driving assembly 2 is arranged on the mounting frame 1.

[0048] The first movable rod 1121 is rotatably mounted on one end of the second swing rod 112 away from the sleeve 114, the angle between the second swing rod 112 and the first movable rod 1121 opens downward, the first horizontal rod 1122 is rotatably mounted on one end of the first movable rod 1121 away from the second swing rod 112, a first limit block 1123 is welded and mounted on the mounting frame 1, and an adsorption mechanism 3 is provided on one end of the first horizontal rod 1122 away from the first movable rod 1121.

[0049] The second movable rod 1131 is rotatably mounted on one end of the third swing rod 113 away from the sleeve 114, the angle between the third swing rod 113 and the second movable rod 1131 is opened upward, the second horizontal rod 1132 is rotatably mounted on one end of the second movable rod 1131 away from the third swing rod 113, a second limit block 1133 is welded and mounted on the mounting frame 1, and a paper supply assembly 4 is provided on one end of the second horizontal rod 1132 away from the second movable rod 1131.

[0050] The driving assembly 2 in the present application can drive the first swing arm 111 to swing in an arc shape with the rotating rod 11 as the center, thereby driving the second swing arm 112 and the third swing arm 113 on the first swing arm 111 to swing in an arc shape in opposite directions synchronously. Under the action of the first movable rod 1121, the first horizontal rod 1122 and the first limit block 1123, the adsorption mechanism 3 performs horizontal movement. Under the action of the second movable rod 1131, the second horizontal rod 1132 and the second limit block 1133, the paper supply assembly 4 performs horizontal movement opposite to the adsorption mechanism 3, thereby realizing the relative movement between the paper supply assembly 4 and the adsorption mechanism 3. The relative movement between the paper supply assembly 4 and the adsorption mechanism 3 can cause slight friction between the adsorbed single packaging paper and the lower packaging paper when the adsorption mechanism 3 adsorbs a single packaging paper, thereby avoiding possible adhesion between the packaging papers, and further ensuring that the adsorption mechanism 3 adsorbs a single packaging paper at a time.

[0051] Compared with the comparative documents, the adsorption mechanism 3 in the present application can realize that the packaging paper pile does not need to be adjusted too finely when placing the packaging paper, and the knocking component, flattening mechanism and straightening mechanism in the prior art are in the same straight line, which prolongs the path and time required to transport the packaging paper to the printing place. Since the paper is relatively soft, if the prior art speeds up the operation speed of the equipment, the flattening mechanism and the straightening mechanism are likely to cause damage to the paper.

[0052] The present application adopts an adsorption method to transfer the packaging paper, which reduces the loss of paper and can increase the operating speed of the driving component 2 and the adsorption mechanism 3 according to actual needs to further improve the efficiency of printing the packaging paper.

[0053] The adsorption mechanism 3 in the present application can also adsorb a single piece of packaging paper. Compared with taking out a single piece of packaging paper from the top or bottom of the packaging paper pile, the disturbance to the packaging paper pile is reduced, and printing errors caused by other packaging papers being pulled when taking out paper can be effectively reduced; the adsorption mechanism 3 can also adjust the position of the packaging paper when the adsorption mechanism 3 transports the single piece of packaging paper to the printing place, thereby improving the quality of printing on the packaging paper, and the paper supply component 4 can continuously provide packaging paper to the adsorption mechanism 3.

[0054] In order to realize the first swing rod 111 to swing back and forth in an arc shape with the rotating rod 11 as the center, refer to Figure 2 and Figure 3 The driving assembly 2 in this embodiment includes a first cam 21, a connecting rod 22 and a first driving motor 23. The first driving motor 23 is mounted on the mounting frame 1, and the connecting rod 22 is rotatably mounted on the mounting frame 1, and one end of the connecting rod 22 is coaxially connected to the output of the first driving motor 23. The first cam 21 is fixedly connected to one end of the connecting rod 22 away from the first driving motor 23. A "T"-shaped annular groove 211 is provided on the side wall of the first cam 21 along the thickness direction, and a cylindrical block 212 is installed in the "T"-shaped annular groove 211, and the cylindrical block 212 is rotatably mounted on one end of the first swing rod 111 close to the first cam 21. When the first cam 21 rotates, it can drive the first swing rod 111 to swing back and forth in an arc with the rotating rod 11 as the center.

[0055] Start the first drive motor 23, and the first drive motor 23 drives the first cam 21 on the connecting rod 22 to rotate. When the first cam 21 rotates, it can drive the cylindrical block 212 at the end of the first swing arm 111 to move in the "T"-shaped ring groove 211, so that the first swing arm 111 can swing in an arc with the rotating rod 11 as the center. When the first swing arm 111 swings, it can drive the second swing arm 112 and the third swing arm 113 to swing in an arc in the opposite direction synchronously, so as to realize the horizontal opposite movement of the adsorption mechanism 3 and the paper supply assembly 4 through the first horizontal rod 1122 and the second horizontal rod 1132.

[0056] When the top or bottom wrapping paper is extracted from the wrapping paper pile, it may cause a large disturbance to the wrapping paper pile, thus affecting the printing of subsequent wrapping papers. Figure 3 and Figure 5 Therefore, the adsorption mechanism 3 in this embodiment includes an air pumping moving box 31, an air pump 32, an air pumping pipe, a negative pressure head 33, a moving component 34 and an adjusting component 35.

[0057] The moving box 31 is slidably installed on the mounting frame 1, and the moving box 31 is welded to the first horizontal rod 1122. The vacuum pump 32, the vacuum pipe and the negative pressure head 33 are all installed in the moving box 31. The moving box 31 and the mounting frame 1 are provided with suction ports for the negative pressure head 33 to extend out. One end of the vacuum pipe is connected to the vacuum pump 32, and the other end is connected to the negative pressure head 33. The moving component 34 can make the negative pressure head 33 extend from the suction port, and the adjustment component 35 can adjust the position of a single piece of packaging paper while transporting it.

[0058] Start the vacuum pump 32, and the vacuum pump 32 generates negative pressure on the surface where the negative pressure head 33 contacts the packaging paper through the vacuum pipe, thereby adsorbing the packaging paper. The negative pressure head 33 in this embodiment is close to the size of the packaging paper, and a plurality of negative pressure ports are provided on the negative pressure head 33 to adsorb and flatten the paper. The moving component 34 can move the negative pressure head 33 up and down, so that when the adsorption mechanism 3 and the paper supply component 4 perform opposite movements, the moving component 34 can transfer the packaging paper from the paper supply component 4 to the printing place.

[0059] The adjustment component 35 can adjust the position of the wrapping paper during the transfer process, so as to facilitate printing on the wrapping paper. Since the adsorption mechanism 3 and the paper supply component 4 move in opposite directions, when the negative pressure head 33 adsorbs the wrapping paper, the adsorbed wrapping paper will generate slight friction with the lower layer of wrapping paper, thereby avoiding possible adhesion between the wrapping papers, and further ensuring that the adsorption mechanism 3 adsorbs a single piece of wrapping paper at a time.

[0060] When the negative pressure head 33 absorbs the packaging paper at the paper supply assembly 4, it needs to abut against the top layer of packaging paper, so it is necessary to slightly press down the packaging paper pile, and rise after absorbing a single piece of packaging paper. When placing the packaging paper at the printing position, it needs to be lowered again. Figure 2 , Figure 4 and Figure 5 Therefore, the moving assembly 34 in this embodiment includes a second cam 341 , a pushing rod 342 and a limiting rod 343 .

[0061] The fixed bin 311 is welded and installed in the mobile box 31, and the mobile bin 312 is slidably installed, the vacuum pump 32 is fixedly installed in the fixed bin 311, the negative pressure head 33 is lifted and installed in the mobile bin 312, the fixed bin 311 is welded and installed above the mobile bin 312, the second cam 341 is welded and installed on the rotating rod 11, the push rod 342 is horizontally movably installed on the mounting frame 1, the end of the push rod 342 away from the rotating rod 11 passes through the side wall of the mobile box 31 and is welded to the side wall of the mobile bin 312, and two groups of limit rods 343 are installed.

[0062] Two groups of limiting rods 343 are welded and installed on the side walls of the negative pressure head 33 perpendicular to the moving direction of the negative pressure head 33. A vertical groove 3121 for the limiting rod 343 to move is opened on the side wall of the mobile bin 312. An arc groove 313 begins to be provided on the side wall of the mobile box 31. The end of the limiting rod 343 away from the negative pressure head 33 is installed in the vertical groove 3121 and the arc groove 313. The arc opening of the arc groove 313 faces downward. When the limiting rod 343 is located at one end of the arc groove 313 close to the push rod 342, the negative pressure head 33 absorbs the packaging paper in the paper supply assembly 4. When the limiting rod 343 is located at one end of the arc groove 313 away from the push rod 342, the negative pressure head 33 places the absorbed packaging paper at the printing position.

[0063] When the rotating rod 11 rotates, it drives the second protrusion to rotate, thereby driving the mobile bin 312 at the end of the push rod 342 to move. When the mobile bin 312 moves, since the end of the limiting rod 343 away from the negative pressure head 33 is arranged in the vertical groove 3121 and the arc groove 313, the limiting rod 343 will move along the shape of the arc groove 313, thereby realizing the same moving trajectory of the negative pressure head 33, thereby realizing the lifting and lowering of the negative pressure head 33 in the mobile bin 312, and while the negative pressure head 33 moves in the mobile bin 312, the mobile box 31 is also moving in the same direction.

[0064] When the mobile box 31 moves to above the printing place, the mobile bin 312 just moves to above the position where the packaging paper is placed at the printing place. The synchronous movement of the mobile box 31 and the mobile bin 312 can further reduce the time required to transfer the packaging paper from the paper supply assembly 4 to the printing place, and further improve the printing efficiency of the packaging paper.

[0065] When the negative pressure head 33 places the packaging paper at the printing position with a large deviation, the printing quality of the packaging paper will be reduced. Figure 5 Therefore, the adjustment component 35 in this embodiment includes a transverse adjustment component 351 and a longitudinal adjustment component 352. The transverse adjustment component 351 in this embodiment aligns the packaging paper perpendicular to the movement direction. The transverse adjustment component 351 includes a moving block 3511, a first clamping block 3512, a first threaded rod 3513 and a first clamping plate 3514.

[0066] Two groups of first threaded rods 3513 are installed, and the two groups of first threaded rods 3513 are respectively rotated and installed in the mobile box 31 along the movement direction of the mobile warehouse 312 and are installed on both sides of the mobile warehouse 312. Two groups of moving blocks 3511 are installed, and the two groups of moving blocks 3511 are welded and installed on the side walls of the mobile warehouse 312, and are respectively threadedly connected with the two groups of first threaded rods 3513. The first clamping block 3512 is threadedly installed on the first threaded rod 3513 and is installed at intervals from the moving block 3511. A first limiting groove 3515 is opened on the first clamping block 3512, and a first limiting strip 3516 is welded and installed on the inner wall of the mobile box 31. The first clamping block 3512 is slidably installed on the first limiting strip 3516 through the first limiting groove 3515, and the first clamping plate 3514 is welded and installed on the side of the first clamping block 3512 away from the vacuum pump 32.

[0067] When the mobile bin 312 drives the mobile block 3511 to move, since the first threaded rod 3513 is rotatably installed on both sides of the mobile bin 312, and the first threaded rod 3513 and the mobile block 3511 are threadedly connected, when the mobile block 3511 moves, the first threaded rod 3513 rotates around itself as the axis, and since the first clamping block 3512 is threadedly connected between the first threaded rod 3513, and the first clamping block 3512 is slidably installed on the first limiting strip 3516 on the inner wall of the mobile box 31 through the first limiting groove 3515, when the first threaded rod 3513 rotates, it can drive the first clamping plate 3514 on the first clamping block 3512 to move, thereby realizing the adjustment of the lateral position of the packaging paper.

[0068] Reference Figure 5 The longitudinal adjustment component 352 in this embodiment is used to align the packaging paper along the direction of movement. The longitudinal adjustment component 352 includes a second clamping block 3521, a second threaded rod 3522, a second clamping plate 3523, an active bevel gear 3524 and a driven bevel gear 3525 wheel. The second threaded rod 3522 is installed in two groups. The two groups of second threaded rods 3522 are respectively installed on both sides of the mobile bin 312 perpendicular to the first threaded rod 3513. The active bevel gear 3524 is welded and installed at the end of the first threaded rod 3513, and the driven bevel gear 3525 wheel is welded and installed at the end of the second threaded rod 3522, and the active bevel gear 3524 and the driven bevel gear 3525 wheel are meshed with each other.

[0069] The second clamping block 3521 is threadedly connected and installed on the second threaded rod 3522. A second limiting groove 3526 is opened on the second clamping block 3521. A second limiting strip 3527 is welded and installed on the inner wall of the movable box 31. The second clamping block 3521 is slidably installed on the second limiting strip 3527 through the second limiting groove 3526. The second clamping plate 3523 is welded and installed perpendicular to the second clamping plate 3523 on the side of the second clamping block 3521 away from the vacuum pump 32.

[0070] When the first threaded rod 3513 rotates, since the active bevel gear 3524 and the driven bevel gear 3525 are meshed with each other, the first threaded rod 3513 can drive the second threaded rod 3522 to rotate, and since the second clamping block 3521 is threadedly connected to the second threaded rod 3522, the second clamping block 3521 is slidably set on the second limiting strip 3527 through the second limiting groove 3526, so it can drive the second clamping plate 3523 on the second clamping block 3521 to move, thereby adjusting the longitudinal position of the packaging paper.

[0071] Reference Figure 6 The paper supply assembly 4 includes a paper storage box 41, a paper placing paper board 42, a support column 43 and an elastic member 44. The paper storage box 41 is slidably mounted on the mounting frame 1, and a paper placing slot 45 is provided on the paper storage box 41. The paper placing paper board 42 is movably installed in the paper placing slot 45 up and down. The support column 43 and the elastic member 44 are both installed in the paper storage box 41. The support column 43 is installed between the inner bottom wall of the paper storage box 41 and the paper placing paper board 42. The elastic member 44 is sleeved on the support column 43. A paper outlet 46 is provided above the paper storage box 41.

[0072] Place the wrapping paper on the paper placing paper board 42 in the paper storage box 41. With the support of the elastic member 44, the upper surface height of the uppermost layer of wrapping paper will be slightly higher than the upper surface of the paper storage box 41. The support column 43 can provide stability for the elastic member 44 and reduce the deformation of the elastic member 44. In the present embodiment, the elastic member 44 is a spring, which is a preferred embodiment of the present embodiment. In other embodiments, the elastic member 44 can be a soft rubber sleeve, etc., and in the present embodiment, in order to facilitate adding wrapping paper to the paper storage box 41, a paper loading hole 12 is opened on the mounting frame 1 in the present embodiment, and a paper loading port 47 is opened on the side wall of the paper storage box 41. After opening the paper loading hole 12 and the paper loading port 47, the paper placing paper board 42 is pressed down and the wrapping paper can be added.

[0073] Reference Figure 7In this embodiment, a printing assembly 5 is also installed on the mounting frame 1. The printing assembly 5 includes a conveyor belt 51, a leveling roller 52, a printing roller 53 and a second driving motor 54. A placement groove is opened on the conveyor belt 51, and the packaging paper is moved into the placement groove through the negative pressure head 33. The printing roller 53 and the second driving motor 54 are both installed on the mounting frame 1, and one end of the printing roller 53 is connected to the output shaft of the second driving motor 54. The leveling roller 52 is installed below the printing roller 53. A driving gear 55 is welded on the printing roller 53, and a driven gear 56 is welded on the leveling roller 52. The driving gear 55 and the driven gear 56 are meshed with each other.

[0074] The conveyor belt 51 moves the packaging paper to between the printing roller 53 and the smoothing roller 52, and starts the second drive motor 54. The second drive motor 54 rotates the printing roller 53. Since the driving gear 55 of the printing roller 53 and the driven gear 56 on the smoothing roller 52 are engaged with each other, the smoothing roller 52 can be driven to rotate synchronously in the opposite direction, thereby realizing the printing of the packaging paper. In this embodiment, the placement groove has a depth equal to the thickness of the packaging paper. The placement groove can improve the stability of the packaging paper on the conveyor belt 51 and reduce the influence of air flow on the position of the packaging paper, thereby further improving the printing quality of the packaging paper.

[0075] The implementation principle of the automatic rapid printing device for cigarette box packaging paper in the embodiment of the present application is as follows:

[0076] The wrapping paper is placed on the paper board 42 of the paper storage box 41. Under the action of the elastic member 44, the uppermost wrapping paper is pushed to the top of the paper placement slot 45. The first driving motor 23 is started. The first driving motor 23 drives the first cam 21 to rotate through the connecting rod 22. The first cam 21 rotates the rotating rod 11. The rotating rod 11 rotates and drives the first swing rod 111 to swing. The first swing rod 111 drives the second swing rod 112 and the third swing rod 113 to swing in opposite directions. The second swing rod 112 drives the adsorption mechanism 3 to move through the first movable rod 1121 and the first horizontal rod 1122. The third swing rod 113 drives the paper supply assembly 4 to move in the opposite direction of the adsorption mechanism 3 through the second movable rod 1131 and the second horizontal rod 1132.

[0077] When the negative pressure head 33 moves to one end of the arc groove 313 close to the second cam 341, the vacuum pump 32 in the adsorption mechanism 3 generates negative pressure on the contact surface between the negative pressure head 33 and the uppermost packaging paper in the paper supply assembly 4 through the vacuum pipe, thereby adsorbing a single packaging sheet; in the process of the negative pressure head 33 moving to the end of the arc groove 313 away from the second cam 341, the moving block 3511 at the bottom of the moving bin 312 drives the first threaded rod 3513 to rotate, and at the same time, under the action of the first limiting groove 3515 and the first limiting strip 3516, the first clamping block 3512 drives the second threaded rod 3513 to rotate. A clamping plate 3514 moves synchronously. When the first threaded rod 3513 rotates, under the action of the active bevel gear 3524 and the driven bevel gear 3525, the first threaded rod 3513 drives the second threaded rod 3522 to rotate, thereby driving the second clamping plate 3523 on the second clamping block 3521 to move synchronously; when the negative pressure head 33 moves to the end of the arc groove 313 away from the second cam 341, the first clamping plate 3514 and the second clamping plate 3523 complete the alignment adjustment of the packaging paper, and the negative pressure head 33 places the adsorbed single packaging paper on the printing component 5.

The second swing rod 112 drives the adsorption mechanism 3 to move through the first movable rod 1121 and the first horizontal rod 1122. The third swing rod 113 drives the paper feeding assembly 4 to move in the opposite direction of the adsorption mechanism 3 through the second movable rod 1131 and the second horizontal rod 1132.

[0081] S3: When the negative pressure head 33 moves to one end of the arc groove 313 close to the second cam 341, the vacuum pump 32 in the adsorption mechanism 3 generates negative pressure on the contact surface between the negative pressure head 33 and the uppermost wrapping paper in the paper supply assembly 4 through the vacuum pipe, thereby adsorbing a single wrapping paper;

[0082] S4: When the negative pressure head 33 moves to the end of the arc groove 313 away from the second cam 341, the moving block 3511 at the bottom of the moving bin 312 drives the first threaded rod 3513 to rotate. At the same time, under the action of the first limiting groove 3515 and the first limiting strip 3516, the first clamping block 3512 drives the first clamping plate 3514 to move synchronously. When the first threaded rod 3513 rotates, under the action of the active bevel gear 3524 and the driven bevel gear 3525, the first threaded rod 3513 drives the second threaded rod 3522 to rotate, thereby driving the second clamping plate 3523 on the second clamping block 3521 to move synchronously.

When the first threaded rod (3513) rotates, under the action of the active bevel gear (3524) and the driven bevel gear (3525), the first threaded rod (3513) drives the second threaded rod (3522) to rotate, thereby driving the second clamping plate (3523) on the second clamping block (3521) to move synchronously. S5: When the negative pressure head (33) moves to the end of the arc-shaped groove (313) away from the second cam (341), the first clamping plate (3514) and the second clamping plate (3523) complete the alignment adjustment of the packaging paper, and the negative pressure head (33) places the absorbed single piece of packaging paper on the printing component (5); S6: The conveyor belt (51) and the second drive motor (54) are started. The conveyor belt (51) moves the positioned packaging paper to the printing roller (53) and the flattening roller (52). The second drive motor (54) drives the printing roller (53) and the flattening roller (52) to rotate synchronously via the driving gear (55) and the driven gear (56), thereby completing the printing work on the packaging paper.
