Description

Technical Field

[0001] The present invention relates to the technical field of cigarette label printing, and specifically to a device and method for removing residues in cigarette label printing. Background Art

[0002] A cigarette label is a label on which a special pattern is printed for display on a cigarette case. In the prior art, when printing cigarette labels, a screen printing machine is required for printing and processing. Subsequently, the printed cigarette label paper is placed in a die-cutting machine. Using a template engraved with a steel knife, a metal mold, a steel wire, or a steel plate, a certain pressure is applied through an impression plate to roll and cut the printed matter or cardboard into a certain shape, so as to cut the large-size cigarette label paper into the size of a finished cigarette case according to the set die-cutting size. During the process of cutting large-size cigarette label paper in the prior art, debris of a certain size will be generated. These debris need to be removed during the die-cutting process. However, during the die-cutting process of the cigarette label paper, the natural wear of the steel knife will occur to varying degrees due to long-term production, resulting in the product being barely broken rather than cut through by the blade edge. In this case, debris is easily generated. Moreover, in a dry environment, friction occurs between the cigarette label paper and the internal structure of the die-cutting machine, generating static electricity. The static electricity will adsorb dust and debris in the air onto the surface of the cigarette label paper, thus affecting the subsequent processing operations of the cigarette label paper. For this, we propose a device and method for removing residues in cigarette label printing to solve the above problems. Summary of the Invention

[0012] Preferably, a method for removing cigarette label printing residues includes the following steps: Step 1: After the staff checks and confirms that there are no foreign objects in the die-cutting machine body, conduct a thorough inspection and adjustment of the machine. Check whether the die-cutting is the same size as the box sample. According to the number of products, paper type, and carton structure, select the bottom template material, install the die-cutting plate, and lock the fixing screws to prevent the die-cutting plate from falling off. Make the bottom template, the thickness of the bottom template is the same as the thickness of the paper for die-cutting products, install the bottom template, clean the surface debris and lock it. According to the paper thickness, adjust the die-cutting pressure. When adjusting, the pressure should be gradually increased from light to heavy until 80% penetration.

Beneficial effects

[0013] Compared with the prior art, the present invention provides a device and method for removing cigarette label printing residues, having the following beneficial effects: Through reciprocating vibration, the paper can be made flatter, reducing deformation caused by stress generated during the die-cutting process. Vibration helps eliminate static electricity generated during the die-cutting process, preventing the cigarette label paper from sticking or adsorbing dust. At the same time, vibration can reduce the warping and deformation of the paper. In addition, in cooperation with the cigarette label paper in an inclined state, vibration can peel off impurities such as debris generated during the cutting process on the surface of the cigarette label paper, maintaining the cleanliness of the surface of the cigarette label paper and facilitating subsequent processing; Two sets of fitting components are respectively arranged to contact the upper surface and the lower surface of the cigarette label paper. Therefore, one set of V-shaped blocks will contact the back surface of the cigarette label paper, limiting the position of the cigarette label paper and generating friction when contacting the back surface of the cigarette label paper, further reducing the dust on the back surface of the cigarette label paper. The other set of V-shaped blocks will contact the surface of the cigarette label paper with a film attached, further smoothing the problems such as wrinkles on the surface of the film and the paper caused by the deformation of the cigarette label paper; By cooperating the V-shaped blocks with the lever in a moving state, the V-shaped blocks can always be in a state of fitting the surface of the cigarette label paper during the process of the lever slightly vibrating the cigarette label paper, effectively suppressing the warping and deformation of the cigarette label paper caused by vibration, and ensuring that the cigarette label paper remains flat; Through the settings of the first pressing rod, the second pressing rod, the rotating shaft and the two levers, the cigarette label paper is in a state of two sections of inclination at this position, thereby assisting the lever in vibrating the surface of the cigarette label paper, avoiding the deformation caused by a large sudden bending amplitude of the cigarette label paper, and reducing the influence of the deformation on the cigarette label paper itself, so as not to affect the subsequent folding operation of the cigarette label paper; Through the intermittent contact between the rubber sleeve and the cigarette label paper, the rubber sleeve is synchronously and periodically in a state of clamping and releasing the cigarette label paper during the movement of the cigarette label paper, assisting the movement of the cigarette label paper inside the device housing, avoiding the situation that after the surface of the cigarette label paper is laminated after preliminary die-cutting, the friction between it and other components is small, resulting in insufficient traction and slipping inside the device housing, and avoiding the situation that the cigarette label paper cannot be smoothly collected; Through the reciprocating movement of the rubber sleeve, the friction between the rubber sleeve and the cigarette label paper can straighten the cigarette label paper that has been bent and deformed in the previous stage, thereby further reducing the influence of the bending and deformation of the cigarette label paper on the subsequent operations.

[0028] Step 1: After the staff checks and confirms that there are no foreign objects in the die-cutting machine body 11, conduct a thorough inspection and adjustment of the machine. Check whether the die-cutting is the same size as the box sample. Select the bottom template material according to the product quantity, paper type, and carton structure. Install the die-cutting plate and lock the fastening screws to prevent the die-cutting plate from falling off. Make the bottom template with the bottom template thickness being the same as the paper thickness of the die-cut product. Install the bottom template, clean the surface debris and lock it. Adjust the die-cutting pressure according to the paper thickness. When adjusting, the pressure should be gradually increased from light to heavy to 80% penetration. Adjust the positions of the upper and lower ejector pins of the paper stripping component and lock them; Step 2: Subsequently, the die-cutting machine body 11 cuts the cigarette label paper. The staff needs to put the mold designed by the designer into the die-cutting machine body 11 and cut the cigarette label paper into the corresponding size according to the size of the designed mold. At the same time, conduct surface treatment on the cigarette label paper, such as coating glue, bronzing, etc. While cutting the cigarette label paper through the die-cutting machine body 11, cut the large-size cigarette label paper into strips; Step 3: Pass the cigarette label paper obtained in Step 1 through between the first pressing rod 52 and the second pressing rod 54 after being processed by the die-cutting machine body 11, bypass the surface of the lever 28, bypass the bottom surface of the rotating shaft 21, then wind out from the surface of another lever 28, and pass through between the round rods 64, and finally wind around the outer surface of the winding roller 13; Step 4: The winding roller 13 rotates driven by an external motor to wind the cigarette label paper around the winding roller 13. Subsequently, the rotation of the rotating shaft 21 drives the lever 28 to pat the surface of the cigarette label paper to remove debris; Step 5: Pass the cigarette label paper wound by the winding roller 13 into another die-cutting machine body 11 for the next-stage die-cutting treatment of the cigarette label paper.

[0029] The working process and principle of the overall content of the above embodiments are as follows: Preparation work: The staff sends the printed cigarette label paper into the die-cutting machine body 11. Through the action of pressure, the die-cutting knife and the indentation knife produce a physical effect on the printing substrate to form punching or indentation. After being cut by the die-cutting machine body 11, one end of the cigarette label paper cut into small sizes passes through between the first pressing rod 52 and the second pressing rod 54, and then the cigarette label paper bypasses the top of the lever 28 near the second pressing rod 54 and passes along the upper surface of the rotating shaft 21, and finally passes under the lever 28 located at the end far from the second pressing rod 54. The cigarette label paper after passing through the lever 28 will continue to pass through between the two symmetrically arranged round rods 64 up and down, and then wind around the winding roller 13; Subsequently, the staff manually rotates the threaded rod 55, causing the threaded rod 55 to rotate inside the rectangular clamping block 51. Moreover, the slider 53 rotatably connected to the bottom of the threaded rod 55 will slide vertically downward inside the rectangular clamping block 51, causing the second pressing rod 54 inside the slider 53 to move downward synchronously, shortening the distance between the first pressing rod 52 and the second pressing rod 54 in the vertical direction. Thus, the first pressing rod 52 and the second pressing rod 54 clamp the cigarette label paper disposed therebetween; Subsequently, the staff manually rotates the knob 56, causing the knob 56 to drive the rectangular clamping block 51 fixedly connected thereto to rotate about the connection point between it and the device housing 12 as a fulcrum, changing the originally vertical rectangular clamping block 51 to an inclined state. After stopping rotating the knob 56, the bottom end of the positioning rod 57 will be clamped in the groove formed on the surface of the knob 56 under the action of the return spring provided on its outer surface, fixing the position of the knob 56.

[0030] Treatment of the cigarette label paper after preliminary die-cutting: The cigarette label paper after preliminary treatment by the die-cutting machine body 11 changes from the original whole paper shell to a strip-shaped paper shell, and the surface of the cigarette label paper has been laminated during the die-cutting process; The winding roller 13 is fixedly connected to the output shaft of the external motor, and the winding roller 13 can be driven to rotate by the external motor. Therefore, the rotation of the winding roller 13 can cause friction with the cigarette label paper wound around its outer surface, causing the cigarette label paper to have a tendency to move, and then pulling the cigarette label paper to move; It should be noted that the contact surface between the winding roller 13 and the cigarette label paper is the back surface, that is, this surface does not need to be attached with a film, so that there is a large frictional force between the cigarette label paper and the winding roller 13, which can cause the cigarette label paper to move under the action of the winding roller 13; During the above process, since the cigarette label paper is initially set to be inserted between the two dial rods 28, the back surface (the side without the attached film) of the cigarette label paper is in a fitting state with the rotating shaft 21, and the outer surface of the rotating shaft 21 is provided with rough lines. In this state, there is a large frictional force between the cigarette label paper and the rotating shaft 21. At this time, when the cigarette label paper rotates under the action of the winding roller 13, it will generate friction with the rotating shaft 21, causing the rotating shaft 21 to rotate; It should be noted that since the cigarette label paper initially bypasses the top of the dial rod 28 near the second pressing rod 54, passes through the upper surface of the rotating shaft 21, and finally passes under the dial rod 28 at the end far from the second pressing rod 54, and both of the two dial rods 28 are provided with fitting components, and the V-shaped blocks 42 in the two groups of fitting components will respectively fit on the upper surface and the lower surface of the cigarette label paper, and the two groups of V-shaped blocks 42 cooperate to limit the position of the cigarette label paper; When the friction between the cigarette label paper and the rotating shaft 21 causes the rotating shaft 21 to rotate, since the two lever rods 28 in the initial state are inclined with respect to the vertical plane, the cigarette label paper restricted within the two lever rods 28 will be in an inclined state with respect to the horizontal plane. During the rotation of the rotating shaft 21, the driven rings 23 fixedly connected to both ends thereof will rotate synchronously inside the device housing 12; Since arc-shaped grooves 24 are equidistantly formed around the center of the driven ring 23 on the surface of the driven ring 23, and a positioning block 31 is sleeved on the surface of the rotating shaft 21, and the bottom end of the clamping rod 32 slidably connected inside the positioning block 31 contacts the groove wall of the arc-shaped groove 24, when the rotating shaft 21 drives the driven ring 23 to rotate, the arc-shaped grooves 24 formed on the driven ring 23 will also change accordingly, and the clamping rod 32 in contact with the groove wall of the arc-shaped groove 24 will receive a force exerted by the groove wall of the arc-shaped groove 24; In the above process, since the groove wall of the arc-shaped groove 24 is not in a horizontal state, the force exerted by the groove wall of the arc-shaped groove 24 on the clamping rod 32 is in an inclined direction. At this time, the force received by the clamping rod 32 can be decomposed into a force in the vertical direction and a force in the horizontal direction. When the clamping rod 32 receives a force in the horizontal direction, the clamping rod 32 will move in the direction close to the first pressing rod 52 under the action of the groove wall of the arc-shaped groove 24. At the same time, the force received by the clamping rod 32 in the vertical direction will cause the clamping rod 32 to move in the vertical direction, resulting in an upward movement in the vertical direction inside the positioning block 31 and compressing the limit spring 33 sleeved on the outer wall of the clamping rod 32; Since the positioning block 31 is rotatably connected to the surface of the rotating shaft 21, the clamping rod 32 will drive the positioning block 31 to deflect at a certain angle on the surface of the rotating shaft 21 with the connection point between the positioning block 31 and the rotating shaft 21 as the fulcrum under the action of the groove wall of the arc-shaped groove 24. And through the fixed connection between the positioning block 31 and the rotary ring 25, the rotary ring 25 will be driven to deflect synchronously on the surface of the rotating shaft 21. The deflection direction is towards the first pressing rod 52 with the rotating shaft 21 as the base point. The rotation of the rotary ring 25 will synchronously drive the lever rod 28 located on its surface to change its position; In addition, since the rotary ring 25 is fixedly connected to the device housing through a torsion spring 26, the rotation of the rotary ring 25 will cause the torsion spring 26 to generate a certain angle of torsion; When one of the arc-shaped grooves 24 rotates until the edge of its groove wall contacts the latch 32, as the driven ring 23 continues to rotate under the action of the rotating shaft 21, the bottom end of the latch 32 disengages from the groove wall of the arc-shaped groove 24. At this time, the convex arc-shaped surface of the driven ring 23 will contact the latch 32. In this state, compared with the groove wall of the arc-shaped groove 24, the horizontal force exerted on the latch 32 by the convex arc-shaped surface of the driven ring 23 is smaller. Therefore, the force indirectly acting on the torsion spring 26 through the latch 32 decreases, and the torsion spring 26 gradually returns to its initial state under the action of its own elastic rebound until it acts on the latch 32 through the rotary ring 25, positioning block 31, etc. in the reverse direction, causing the latch 32 to return to the vertical state again. Until with the rotation of the driven ring 23, the bottom end of the latch 32 contacts the next arc-shaped groove 24 again. When the next arc-shaped groove 24 rotates to the middle part and contacts the bottom end of the latch 32, the latch 32 returns to its initial position in both the vertical and horizontal directions, and cycles with the rotation of the rotating shaft 21 driving the driven ring 23; During the above process, with the reciprocating swing of the positioning block 31 driving the rotary ring 25, the two toggle levers 28 fixedly connected to the surface of the rotary ring 25 will also move accordingly and continuously contact the surface of the cigarette label paper, making the surface of the cigarette label paper present a state of small-amplitude vibration. Through the reciprocating vibration, the paper can be made flatter, reducing the deformation caused by the stress generated during the die-cutting process. The vibration helps to eliminate the static electricity generated during the die-cutting process, preventing the cigarette label paper from sticking or adsorbing dust. At the same time, the vibration can reduce the warping and deformation of the paper. In addition, in cooperation with the cigarette label paper in an inclined state, the vibration can peel off impurities such as debris generated during the cutting process on the surface of the cigarette label paper, maintaining the cleanliness of the surface of the cigarette label paper and facilitating subsequent processing; During the above process, the fitting assembly is arranged on the surface of the toggle lever 28. Therefore, the surface of the V-shaped block 42 in the fitting assembly will contact the cigarette label paper. As the position of the toggle lever 28 changes, the V-shaped block 42 arranged on the surface of the toggle lever 28 will simultaneously receive the synchronous force from the surface of the cigarette label paper and the toggle lever 28. This force will act on the return springs 43 arranged at both ends of the V-shaped block 42 through the V-shaped block 42, causing a certain degree of deformation of the return springs 43, so that the surface of the V-shaped block 42 always fits the surface of the cigarette label paper. And because the two fitting assemblies are respectively arranged in contact with the upper surface and the lower surface of the cigarette label paper, one of the V-shaped blocks 42 will contact the back surface of the cigarette label paper, limiting the position of the cigarette label paper and generating friction when contacting the back surface of the cigarette label paper, further reducing the presence of dust on the back surface of the cigarette label paper. The other V-shaped block 42 will contact the surface of the cigarette label paper with a film attached, further smoothing out problems such as wrinkles on the surface of the film and the paper caused by the deformation of the cigarette label paper; By cooperating the V-shaped block 42 with the lever 28 in the moving state, the V-shaped block 42 can always be in a state of fitting the surface of the label paper during the process of the lever 28 slightly vibrating the label paper, effectively suppressing the warping and deformation of the label paper caused by vibration, and ensuring that the label paper remains flat; At the same time, when the device is running, the rectangular block 51 is in an inclined state, and the vertical height of the first pressing rod 52 and the second pressing rod 54 is higher than the vertical height of the lever 28 and the rotating shaft 21. Therefore, the label paper passing through between the first pressing rod 52 and the second pressing rod 54 and the subsequent label paper bypassing the surfaces of the lever 28 and the rotating shaft 21 will also be in an inclined state. Furthermore, the label paper between the first pressing rod 52 and the lever 28 (this lever 28 is located on the side far from the second pressing rod 54) will be in a state of two sections of inclination, and the inclination amplitudes are different. Through the settings of the first pressing rod 52, the second pressing rod 54, the rotating shaft 21 and the two levers 28, the label paper is in a state of two sections of inclination at this position, thereby assisting the lever 28 in vibrating the surface of the label paper, avoiding the deformation caused by a large sudden bending amplitude of the label paper, and reducing the influence of this deformation on the label paper itself, so as to avoid affecting the subsequent folding operation of the label paper.

[0031] Further processing of the label paper: During the above process, with the rotation of the rotating shaft 21, the first connecting rod 61 fixedly connected to both ends of the rotating shaft 21 will move under the action of the rotating shaft 21. Since the connection point of the first connecting rod 61 and the rotating shaft 21 is located at a position deviating from the center of the rotating shaft 21, the first connecting rod 61 will rotate around the center of the rotating shaft 21 under the continuous rotation of the rotating shaft 21, and then drive the driven block 63 to make a reciprocating horizontal movement in the chute opened on the outer surface of the device housing 12 through the second connecting rod 62 rotatably connected to the first connecting rod 61; And during the reciprocating movement of the driven block 63, the two round rods 64 slidably connected inside the driven block 63 will follow to make a reciprocating horizontal movement. Since both ends of the round rod 64 are synchronously slidably connected in the inclined chute 66 penetratingly opened on the device housing 12, and the inclined chutes 66 are symmetrically opened on the surface of the device housing 12, the distance between the two inclined chutes 66 on the same side is getting larger and larger (the reference direction is from the rotating shaft 21 towards the driven block 63, specifically refer to Figure 5 ), so the round rod 64 will be restricted by the inclined chute 66 synchronously during the movement, and the distance between the two round rods 64 is getting larger and larger. The round rod 64 compresses the damping spring 65 arranged on its surface synchronously while moving. And when the second connecting rod 62 drives the driven block 63 to return to the initial position (that is, the end of the inclined chute 66 close to the rotating shaft 21), the round rod 64 will return to the initial state under the action of the elastic deformation force of the inclined chute 66 and the damping spring 65, and the distance between the two round rods 64 gradually becomes smaller. The above process continues with the rotation of the rotating shaft 21; Therefore, the rubber sleeve 67 disposed on the outer surface of the round rod 64 will move synchronously with the round rod 64. In the initial state, the rubber sleeve 67 is in a state of clamping the cigarette label paper located between the two round rods 64. And along with the movement of the round rod 64, the rubber sleeve 67 moves synchronously, and the distance between its surface and the surface of the cigarette label paper gradually increases. At this time, the surface of the rubber sleeve 67 is separated from the contact with the cigarette label paper. Subsequently, after the distance between the round rods 64 gradually returns to the initial state, the rubber sleeve 67 synchronously resumes the state of contacting the surface of the cigarette label paper; In the above process, through the intermittent contact between the rubber sleeve 67 and the cigarette label paper, the rubber sleeve 67 is synchronously and periodically in a state of clamping the cigarette label paper and releasing the cigarette label paper during the movement of the cigarette label paper, assisting the movement of the cigarette label paper inside the device housing 12, and avoiding the situation that after the surface of the cigarette label paper is laminated after preliminary die-cutting, the friction between it and other components is small, resulting in insufficient traction and slipping inside the device housing 12, and avoiding the situation that the cigarette label paper cannot be smoothly bundled; At the same time, through the reciprocating movement of the rubber sleeve 67, the friction between the rubber sleeve 67 and the cigarette label paper can straighten the cigarette label paper that has been bent and deformed in the previous stage, thereby further reducing the influence of the bending deformation of the cigarette label paper on the subsequent operations; As the device continues to operate, the cigarette label paper after the winding roller 13 will enter the next stage of the die-cutting machine body 11 for the next stage of processing operation.
