Description

Technical Field

[0001] The invention relates to the technical field of printing, and in particular to a continuous and precise positioning printing mechanism for cigarette labels. Background Art

[0002] Cigarette labels are the trademarks of cigarette products and are also important carriers of brand image. Cigarette label printing organizations accurately present the logo, pattern, text and other information of tobacco brands on cigarette labels through exquisite design and high-quality printing, thereby displaying the brand image and enhancing brand awareness and reputation. This is of great significance to the marketing promotion and consumer recognition of tobacco brands.

[0003] During the printing process, cigarette labels are often printed in batches in strips due to the characteristics of the printing press and efficiency considerations. This strip-shaped printing can maximize the use of the printing press's layout and improve printing efficiency. After printing, the cigarette labels also need to go through a cutting process to cut them into the size and shape that meet the product requirements.

[0004] There will be some scraps of cigarette labels in the future, which can still be used, but the shape of the scraps is limited. They need to be cut into the shape of cigarette labels before printing to improve material utilization and reduce production costs. However, when printing, the cigarette labels need to be stacked and transferred and printed continuously to avoid changes in the printing position and ensure that the cigarette labels do not stick to each other or misalign, so as to ensure accuracy and stability during printing. However, when transferring and printing cigarette labels continuously, the required structure is complex, and when the cigarette labels are stuck or discontinuous, it will cause printing errors. Based on this, improvements are proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a cigarette label continuous and precise positioning printing mechanism to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a continuous and precise positioning printing mechanism for cigarette labels, comprising a base and a printing device mounted on the base, both sides of the base are fixed with limited sheet metal, and the limited sheet metal is used to clamp the printing device;

[0007] The base is also provided with an external connection part, which includes a metal frame, a clamping plate and a positioning plate. The metal frame is installed between the limit sheet metals on both sides. The positioning plate is provided with two pieces for clamping the cigarette label in the metal frame. The clamping plate is installed in the metal frame and can be adjusted up and down. A blocking frame is installed at the lower end of the clamping plate, and the blocking frame is used to adjust the cigarette label to achieve continuous outward movement.

[0008] Two transmission sheet metal layers are also installed at the lower end of the metal frame, and transmission belts that can transmit power are installed on the two transmission sheet metal layers. The transmission belts are fitted to the cigarette label at the lower end and are used to drive the cigarette label to move.

[0009] Furthermore, a discharge port is provided on one side of the metal frame for transmitting the cigarette labels outward.

[0010] Furthermore, inner supporting sheet metals are fixed to the four corners of the metal frame, wherein a clamping layer is fixed to the symmetrical sides of two inner supporting sheet metals, and the clamping layer is used to clamp the card board so that the card board can be adjusted up and down.

[0011] Furthermore, the two positioning plates are fixed in the metal frame, and positioning strips are fixed on the inner side of the two positioning plates. The upper end surface of the positioning strips is an inclined surface, and the spacing between the positioning strips on both sides is the width of the cigarette label.

[0012] Furthermore, the blocking frame includes an inclined plate and a plurality of blocking shafts, the inclined plate is fixed at the lower end of the card plate, and the plurality of blocking shafts are rotatably installed in the card plate, the blocking shafts are used to abut against the cigarette labels, and the inclined plate also abuts against the overlapping cigarette labels.

[0013] Furthermore, the transmission sheet metal layers on both sides are clamped at the lower end of the metal frame, and the transmission sheet metal layers on both sides are flush with the edges of both ends of the metal frame respectively, an inner opening is opened on the transmission sheet metal layer, a rotating shaft is rotatably installed in the inner opening, the transmission belt is installed on the two rotating shafts, and the transmission belt is in contact with the inner wall of the metal frame;

[0014] A belt is driven between the rotating shaft on one side and the outermost blocking shaft, and belts are also driven between a plurality of the blocking shafts;

[0015] The gap between the transmission belt and the inclined plate is the gap through which the cigarette labels pass.

[0016] Furthermore, the diameter of the blocking shaft is the same as the thickness of the cigarette label.

[0017] Furthermore, a gear 1 is fixed to the end of the rotating shaft on one side, a strip-shaped mating opening is opened on the outer side of the metal frame, an output shaft is inserted into the mating opening, and a gear 2 is fixed to the end of the output shaft. The output shaft is U-shaped, and its two ends are extended laterally. The width of the mating opening is the same as the diameter of the output shaft, and the U-shaped part of the output shaft is located in the mating opening. The output shaft rotates to realize the up and down vibration of the external connection part, and the gear 1 realizes the up and down vibration, and it meshes with the gear 2 when it moves upward.

[0018] Furthermore, the outer side of the limiting sheet metal has a slide groove, the inner wall of the slide groove is provided with a slide opening arranged along the slide groove, the transmission sheet metal layer is embedded in the slide groove and its outer end extends into the slide opening;

[0019] The outer end of the output shaft extends out from the sliding opening, a servo motor is fixed to the outer end of the limiting sheet metal, and the output end of the servo motor is connected to the output shaft.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] 1. The bottommost cigarette label stacked in the metal frame is driven by the transmission belt to move. After the bottommost cigarette label passes through, the upper one continues to pass. The printing equipment can achieve precise positioning to avoid the cigarette label transmission interval being too long or unstable, resulting in inaccurate printing by the printing equipment. When the printing equipment is printing uninterruptedly, the cigarette labels are also continuously transmitted. The speeds of the two are kept consistent. By setting the parameters well, the printing position can be accurate.

[0022] 2. Except for the lowest cigarette label that can pass through the inclined plate, the upper cigarette label is clamped by the blocking shaft. The blocking shaft can rotate in the opposite direction of the movement of the cigarette label, pushing the cigarette label inward to prevent the stacked cigarette labels from being squeezed to the inside of the inclined plate as they move. This setting makes the movement of the cigarette labels smoother, maintains relatively continuous transmission, and realizes continuous printing.

[0023] 3. When the output shaft rotates, the metal frame can generate vibrations. The vibrations can help break the adhesion between the cigarette labels and prevent the cigarette labels from piling up due to excessive cohesion during the transmission process. It helps to keep the paper loose, thereby improving the stability and efficiency of the transmission. Secondly, the vibrations can reduce the misalignment and paper jams of the cigarette labels during the transmission process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 12 The present invention provides a technical solution: a cigarette label continuous accurate positioning printing mechanism, such as Figure 1 As shown, it includes a base 1 and a printing device 3 installed on the base 1, and both sides of the base 1 are fixed with limited sheet metal 2, and the limited sheet metal 2 is used to clamp the printing device 3;

[0040] like Figure 2 and Figure 3As shown, an external connection part 4 is also installed on the base 1, and the external connection part 4 is used to transfer the stacked cigarette labels, and the transfer is continuous, so that the printing device 3 can print continuously, and the error generated is small. The external connection part 4 includes a metal frame 41, a card plate 43 and a positioning plate 44. The metal frame 41 is installed between the limiting sheet metals 2 on both sides. The positioning plate 44 has two pieces, which are used to limit and clamp the cigarette label in the metal frame 41. The card plate 43 is installed in the metal frame 41 and can be adjusted up and down. The lower end of the card plate 43 is installed with a blocking frame 45, and the blocking frame 45 is used to adjust the cigarette label to achieve continuous outward movement;

[0041] Two transmission sheet metal layers 46 are also installed at the lower end of the metal frame 41, and transmission belts 463 that can transmit power are installed on the two transmission sheet metal layers 46. The transmission belts 463 are in contact with the cigarette label at the lower end and are used to drive the cigarette label to move.

[0042] like Figure 8 As shown, the stacked cigarette labels are transmitted one by one, and a discharge port 411 is opened on one side of the metal frame 41 for transmitting the cigarette labels outward. The discharge port 411 is used to transmit the cigarette labels, and at the same time, the transmitted cigarette labels directly enter the printing device 3 to avoid the transmitted cigarette labels being affected by the outside world.

[0043] like Figure 7 As shown, the four corners of the metal frame 41 are fixed with internal supporting sheet metals 42, wherein the two internal supporting sheet metals 42 are symmetrically fixed with clamping layers 421 on one side, and the clamping layers 421 are used to clamp the card board 43 so that the card board 43 can be adjusted up and down. The card board 43 is a baffle for the movement direction of the cigarette labels, and the stacked cigarette labels, that is, the cardboard, can be pulled by the transmission belt 463 at the lower end, so that the lowest cigarette label moves with the movement, and the other cigarette labels are blocked by the card board 43.

[0044] like Figure 3 and Fig.12 As shown, the stacked cigarette labels need to be stacked neatly, and the stacked cigarette labels will not be offset or tilted when subjected to external forces. Two positioning plates 44 are fixed in the metal frame 41, and positioning strips 441 are fixed on the inner side of the two positioning plates 44. The upper end surface of the positioning strip 441 is an inclined surface, and the spacing between the positioning strips 441 on both sides is the width of the cigarette label. The function of the positioning strip 441 is to move the inserted cigarette label along the inclined surface of the positioning strip 441, so that the cigarette labels located between the positioning strips 441 on both sides are stacked neatly, and the cigarette labels are automatically aligned under the action of vibration.

[0045] like Figure 5 and Figure 6 As shown, the blocking frame 45 includes an inclined plate 451 and a plurality of blocking shafts 452. The inclined plate 451 is fixed to the lower end of the card plate 43. The plurality of blocking shafts 452 are arranged and rotatably mounted in the card plate 43. The blocking shafts 452 are used to abut against the cigarette labels, and the inclined plate 451 also abuts against the stacked cigarette labels.

[0046] The stacked cigarette labels driven by the transmission belt 463 will be blocked by the card plate 43, but due to the limited thickness of the cigarette label paper, it is easy to cause multiple sheets to move out together or cause a jam. Therefore, an inclined plate 451 is provided to make the edges of multiple cigarette labels in motion in a stepped shape to reduce the possibility of multiple sheets moving together or causing a jam. In addition, a plurality of blocking shafts 452 are provided, which can move in the same direction as the rotation direction of the rotating shaft 462, such as Figure 8 As shown, the ends of the lowest few cigarette labels are against a plurality of blocking shafts 452, which rotate opposite to the direction of movement of the cigarette labels and also have the effect of lifting the cigarette labels upward, thereby blocking the multiple cigarette labels and preventing them from moving outward.

[0047] like Figure 4 and Fig. 9 As shown, the transmission sheet metal layers 46 on both sides are clamped at the lower end of the metal frame 41, and the transmission sheet metal layers 46 on both sides are flush with the edges of the two ends of the metal frame 41, and an inner opening 461 is opened on the transmission sheet metal layer 46, and a rotating shaft 462 is rotatably installed in the inner opening 461. The transmission belt 463 is transmission-installed on the two rotating shafts 462, and the transmission belt 463 is in contact with the inner wall of the metal frame 41, so that the transmission belt 463 drives the cigarette label at the bottom to move;

[0048] A belt is driven between the rotating shaft 462 on one side and the outermost blocking shaft 452, and a belt is also driven between the plurality of blocking shafts 452 to drive the plurality of blocking shafts 452 to rotate;

[0049] The gap between the transmission belt 463 and the inclined plate 451 is the gap for the cigarette labels to pass through, and only a single cigarette label can pass through.

[0050] like Figure 8 As shown, the diameter of the blocking shaft 452 is the same as the thickness of the cigarette labels. Except for the cigarette labels on the bottom layer, several cigarette labels near the lower end are in contact with their own blocking shafts 452 to achieve a blocking effect.

[0051] like Figure 6 and Fig.10As shown, a gear 1 464 is also fixed to the end of the rotating shaft 462 on one side, and a strip-shaped mating opening 467 is opened on the outer side of the metal frame 41, and an output shaft 466 is inserted in the mating opening 467, and a gear 2 465 is fixed to the end of the output shaft 466. The output shaft 466 is U-shaped, and its two ends are extended laterally. The width of the mating opening 467 is the same as the diameter of the output shaft 466, and the U-shaped part of the output shaft 466 is located in the mating opening 467. The output shaft 466 rotates to realize the vibration of the external connection part 4 in the up and down directions, and the gear 1 464 realizes the up and down vibration, and it meshes with the gear 2 465 when it moves upward. The output shaft 466 rotates to drive the external connection part 4 to vibrate in the up and down directions, and the gear 1 464 meshes with the gear 2 465 when it moves upward, realizing intermittent driving movement of the transmission belt 463. The stacked cigarette labels keep the paper in a loose state during the vibration, which makes it easier to realize continuous transmission and make the transmission stable.

[0052] like Figure 2 and Fig.10 As shown, the outer side of the limiting sheet metal 2 has a slide groove 21, the inner wall of the slide groove 21 is provided with a slide opening 22 arranged along the slide groove 21, and the transmission sheet metal layer 46 is embedded in the slide groove 21 and its outer end extends into the slide opening 22;

[0053] The outer end of the output shaft 466 extends from the sliding opening 22, and a servo motor 5 is fixed to the outer end of the limiting sheet metal 2. The output end of the servo motor 5 is connected to the output shaft 466, so that the external connection part 4 is driven to vibrate during the operation of the servo motor 5.

[0054] The working principle of the present invention is as follows: the cigarette labels are stacked in the metal frame 41, and the output shaft 466 is rotated under the action of the servo motor 5. Since the output shaft 466 is U-shaped, the metal frame 41 will be driven to vibrate in the up and down directions during the rotation. When the U-shaped part moves to the upper and lower sides, the metal frame 41 moves in the up and down directions. When the U-shaped part moves to the left and right sides, the length of the matching opening 467 can prevent the metal frame 41 from moving left and right. In addition, the rotation of the output shaft 466 also drives the gear 2 465 to rotate, and intermittently cooperates with the gear 1 464 to realize the intermittent movement of the transmission belt 463.

[0055] Based on the above description, the lowest cigarette label stacked in the metal frame 41 is driven by the transmission belt 463 to move, and has a driving effect on the stacked cigarette labels, so that part of the cigarette labels at the lower end fit with the blocking frame 45, and the lowest cigarette label can pass through the gap between the inclined plate 451 and the transmission belt 463. After the lowest cigarette label passes through, the upper label continues to pass through to achieve the connecting movement, and the printing device 3 can achieve precise positioning to avoid the cigarette label transmission interval being too long or unstable, resulting in inaccurate printing by the printing device 3.

[0056] Secondly, Figure 8As shown, the dotted lines represent stacked cigarette labels. Except for the bottom cigarette label that can pass through the inclined plate 451, the upper cigarette label is clamped by the blocking shaft 452. The blocking shaft 452 is connected to the edge of the cigarette label, and the blocking shaft 452 can rotate in the opposite direction of the movement of the cigarette label to push the cigarette label inward to prevent the stacked cigarette labels from being squeezed to the inside of the inclined plate 451 as they move. The more they are squeezed, the tighter they are. This setting makes the movement of the cigarette labels smoother, relatively maintains continuous transmission, and realizes continuous printing.

[0057] Secondly, when the output shaft 466 rotates, the metal frame 41 can vibrate, which can help break the adhesion between the cigarette labels, prevent the cigarette labels from piling up due to excessive agglomeration during the transmission process, and help keep the paper in a loose state, thereby improving the stability and efficiency of transmission. Secondly, the vibration can reduce the misalignment and paper jam of the cigarette labels during the transmission process;

[0058] In addition, the stacked cigarette labels are clamped by two positioning plates 44, and as the cigarette labels move downward, they are limited by the positioning strips 441 on both sides, further keeping the cigarette labels neat during the stacking process.
