Description

Technical Field

[0001] The invention relates to the technical field of cigarette packaging, and in particular to a device for ironing transparent paper for cigarette strips. Background Art

[0002] In the current production process of cigarette packaging, when small cigarette packs and large cigarette strips are wrapped in heat-shrink film with transparent paper, the long ends are first folded and ironed, and then the two ends are folded and ironed. The ironing of the long sides relies on a connecting rod mechanism to perform the ironing action, causing the ironing iron to move in a circular trajectory to iron the cigarette pack. This is very easy to cause wrinkles on the long side buckles, causing the long sides to be ironed into a wavy state, affecting the appearance of the cigarette packs and cigarette strips. Even with the use of beautifiers and other methods after the packaging is formed, it is difficult to solve the wavy problem of the long side buckles by ironing again. Summary of the Invention

[0003] The purpose of the present invention is to provide a device for ironing transparent paper for cigarette packs in order to solve the problem that the transparent paper packaging of cigarette packs is easily wrinkled, causing the long edges to be ironed into a wavy state, which affects the appearance of the cigarette packs and cigarette rods.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A device for ironing transparent paper for cigarette packs, comprising:

[0006] Strip bag conveying bottom plate;

[0007] Two brackets are provided on both sides of the upper portion of the strip bag conveying bottom plate;

[0008] A strip pack pressing plate mechanism is movably mounted on the upper ends of the two brackets;

[0009] a soldering iron mechanism, movably mounted on the lower portion of the cigarette pack conveying bottom plate and located directly below the cigarette pack pressing plate mechanism, and forming an ironing station together with the cigarette pack pressing plate mechanism for ironing the transparent paper of the cigarette pack;

[0010] The power drive mechanism is transmission-connected to one end of the soldering iron mechanism and is used for driving the soldering iron mechanism to move up and down.

[0011] After the transparent paper packaging is folded, the cigarette carton is conveyed to the carton conveying bottom plate, and then transported to the ironing station through the package pushing movement. The power drive mechanism drives the soldering iron mechanism to move, and the soldering iron mechanism and the carton pressing plate mechanism form fixed upper and lower warehouses to iron the long side of the transparent paper of the passing cigarette carton.

[0012] Furthermore, the stick pack pressing plate mechanism includes a pressing plate and a stick pack pressing plate installed at the lower part of the pressing plate through a connecting piece, and the lower part of the stick pack pressing plate is in contact with the stick pack cigarettes.

[0013] Further, both the pressing plate and the strip pack pressing plate are long strip-shaped plates. One end of the pressing plate is hinged to the bracket, and the other end of the pressing plate can move upward relative to the bracket.

[0014] Further, a tension spring capable of pulling up the pressing plate is provided at one end of the pressing plate hinged to the bracket;

[0015] A handle unit is provided between the other end of the pressing plate and the bracket. The handle unit includes a mounting block, a handle, a fixed seat, an outer spring hook and an inner spring hook. The mounting block is mounted on the upper end of the pressing plate. The handle is fixedly connected to the mounting block. The outer spring hook is mounted in a groove of the mounting block, and the inner spring hook is mounted in a groove in the fixed seat.

[0016] When it is necessary to take the strip pack cigarette at the ironing position due to human reasons, manually pull the handle. The outer spring hook is disengaged from the inner spring hook, and the tension spring pulls up the pressing plate, thereby driving the strip pack pressing plate away from the upper end surface of the strip pack cigarette, and the strip pack cigarette can be taken out smoothly; when taking out the strip pack cigarette, manually pull down the handle, and after the inner spring hook retracts, it is reset by the spring and is mutually limited with the outer spring hook to fix the strip pack pressing plate.

[0017] Further, the soldering iron mechanism includes a soldering iron pressure rod and a soldering iron plate mounted on the upper part of the soldering iron pressure rod. The upper part of the soldering iron plate is in contact with the strip pack cigarette.

[0018] Further, the power driving mechanism includes a swing rod and a power shaft connected to the swing rod. One end of the soldering iron pressure rod is hinged to the swing rod through a connecting rod, and the other end of the soldering iron pressure rod is hinged to a push plate. The power driving mechanism swings to form a swing of the soldering iron pressure rod with the push plate as the center and moves around the rotation axis of the push plate.

[0019] Further, a cylinder is provided on the upper part of the push plate. The cylinder is mounted on the bracket. The cylinder acts to drive the push plate to move downward, so that the soldering iron pressure rod together with the soldering iron plate moves downward and separates from the strip pack cigarette.

[0020] When the equipment stops for too long, in order to prevent the soldering iron plate from moving to the ironing time period and the soldering iron plate cannot be cooled immediately, which is likely to cause damage to the strip pack cigarette. Therefore, after the equipment stops, a signal is given through the solenoid valve to push the push plate by the cylinder, so that the soldering iron pressure rod rotates around the rotation axis of the connecting rod, and the soldering iron plate is far away from the strip pack cigarette to protect the ironing quality of the strip pack cigarette.

[0021] Further, the strip pack pressing plate mechanism is perpendicular to the length direction of the strip pack conveying bottom plate, and the length direction of the strip pack pressing plate mechanism is parallel to the length direction of the strip pack cigarette.

[0022] The ironing device irons the transparent paper of the strip pack cigarette, and specifically includes the following steps:

[0023] (1) For cigarettes packed in a strip by transparent paper, first fold the two side faces at both ends of the strip-packed cigarettes. After folding and ironing at both ends, then perform pre-ironing and dot-ironing treatments at the long-side ironing position; the forms of pre-ironing and dot-ironing can ensure that the transparent paper does not come apart during the folding process at both ends.

[0024] (2) After the folding of the transparent paper packaging is completed, convey the strip-packed cigarettes to the strip-conveying bottom plate of the ironing device. The strip-packed cigarettes are conveyed to the ironing station through the pushing and packing movement mode, and the long side of the strip-packed cigarettes is ironed.

[0025] The moving direction of the strip-packed cigarettes described in step (2) is perpendicular to the position of the long-side buckle, which can effectively prevent the generation of wavy lines and improve the appearance quality of the cigarette packs and strip packs.

[0026] In the original mechanism, after folding the transparent paper, when its transmission mechanism irons the long side, since the soldering iron moves in a circular arc around a rotation center, that is, a rotational movement, but because the soldering iron is flat, when it contacts the strip pack, it first contacts in a line and finally contacts in a surface. Therefore, when the strip pack stops moving during rotation, the compression of the strip pack will change, and the force of the soldering iron on the folded edge of the strip pack will change. When the force changes, the soldering iron also has a certain temperature, and the transparent paper will be ironed at different positions according to the temperature and force, resulting in wrinkling phenomena; after the improvement of the present invention, the movement of the soldering iron is perpendicular to the strip pack, and the whole process is surface contact, so no wavy lines will be caused.

[0027] Compared with the prior art, in order to solve the problems that the transparent paper packaging of cigarette packs is prone to wrinkling and the long side is ironed into a wavy state, affecting the beauty of cigarette packs and cigarette strips, the present invention adopts the method of first folding and ironing the two side faces at both ends, and then performing long-side ironing. At the original ironing position, the long-side buckle ironing is changed to the form of pre-ironing and dot-ironing, which can ensure that the transparent paper does not come apart during the folding process at both ends. After folding and ironing at both ends, then perform long-side ironing; when ironing the long side, by changing the structure of the original ironing soldering iron that moves in a circular arc trajectory, the long-side soldering iron is made to move in a straight line after changing the mechanical structure, ensuring that the movement direction is perpendicular to the position of the long-side buckle, which can effectively prevent the generation of wavy lines and improve the appearance quality of cigarette packs and strip packs.

DETAILED DESCRIPTION

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 , 3 4. A device for ironing transparent paper for cigarette packs, comprising:

[0036] Strip bag conveying bottom plate 5;

[0037] Two brackets: inner bracket 2 and outer bracket 6, which are arranged on both sides of the upper part of the bag conveying bottom plate 5;

[0038] The strip packing pressing plate mechanism is movably mounted on the upper ends of the two brackets;

[0039] The iron mechanism is movably mounted on the lower portion of the strip pack conveying bottom plate 5 and is located directly below the strip pack pressing plate mechanism, forming an ironing station for ironing the transparent paper of the strip pack 13 together with the strip pack pressing plate mechanism;

[0040] The power driving mechanism is connected to one end of the soldering iron mechanism and is used to drive the soldering iron mechanism to move up and down.

[0041] The length direction of the cigarette pack pressing plate mechanism is perpendicular to the length direction of the cigarette pack conveying bottom plate 5 , and the length direction of the cigarette pack pressing plate mechanism is parallel to the length direction of the cigarette pack 13 .

[0042] Specifically, the pack pressing plate mechanism includes a pressing plate 3 and a pack pressing plate 4 mounted below the pressing plate 3 via a connector (e.g., a connecting screw). The lower portion of the pack pressing plate 4 is in contact with the pack 13. Both the pressing plate 3 and the pack pressing plate 4 are elongated plates. One end of the pressing plate 3 is hinged to the inner bracket 2, and the other end of the pressing plate 3 can move upward relative to the outer bracket 6, facilitating the use of the pack when it is necessary to hold the pack in the ironing position for human reasons.

[0043] like Figure 3 , a tension spring 15 is provided at one end of the pressing plate 3 hinged to the bracket to pull up the pressing plate 3. Figure 2, a handle unit is provided between the other end of the pressing plate 3 and the bracket. The handle unit includes a mounting block 18, a handle 9, a slider 19, an outer spring hook 7 and an inner spring hook 8. The mounting block 18 is mounted on the upper end of the pressing plate 3. The slider 19 is mounted in a groove in the mounting block 18. The handle 9 is fixedly connected to the slider 19. The outer spring hook 7 and the inner spring hook 8 are respectively mounted outside and inside the slider 19. When it is necessary to take out the strip-packaged cigarette 13 at the ironing position due to human reasons, the handle 9 is manually pulled. The outer spring hook 7 and the inner spring hook 8 are disengaged, and the tension spring 15 pulls up the pressing plate 3, thereby driving the strip-packaging pressing plate 4 away from the upper end surface of the strip-packaged cigarette 13, and the strip-packaged cigarette 13 can be taken out smoothly. When taking out the strip-packaged cigarette 13, the handle 9 is pulled down manually. After the inner spring hook 8 retracts, it is mutually limited with the outer spring hook 7 through spring reset, so that the strip-packaging pressing plate 4 is fixed.

[0044] As Figure 3 , 4 , the soldering iron mechanism includes a soldering iron pressure rod 12 and a soldering iron plate 17 mounted on the upper part of the soldering iron pressure rod 12. The upper part of the soldering iron plate 17 is in contact with the strip-packaged cigarette 13. The power driving mechanism includes a swing rod 1 and a power shaft 14 connected to the swing rod 1. One end of the soldering iron pressure rod 12 is hinged to the swing rod 1 through a connecting rod 16. The other end of the soldering iron pressure rod 12 is hinged to a push plate 11. The power driving mechanism swings to form a swing of the soldering iron pressure rod 12 with the push plate 11 as the center and rotates around the rotation axis of the push plate 11, so as to realize the soldering iron pressure rod 12 driving the soldering iron plate 17 to move up and down in a straight line, ensuring that the movement direction is perpendicular to the long side buckle position.

[0045] In addition, a cylinder 10 is provided on the upper part of the push plate 11. The cylinder 10 is mounted on the outer bracket 6. The cylinder 10 acts to drive the push plate 11 to move downward, so that the soldering iron pressure rod 12 together with the soldering iron plate 17 moves downward and separates from the strip-packaged cigarette 13. When the equipment stops for too long, in order to prevent the soldering iron plate 17 from moving to the ironing time period and the soldering iron plate 17 cannot be cooled immediately, which is likely to cause damage to the strip-packaged cigarette 13. Therefore, after the equipment stops, a signal is given through the solenoid valve to push the cylinder 10 to drive the push plate 11, so that the soldering iron pressure rod 12 rotates around the rotation axis of the connecting rod 16, and the soldering iron plate 17 is far away from the strip-packaged cigarette 13 to protect the ironing quality of the strip-packaged cigarette 13.

[0046] When using this device for ironing the transparent paper of strip-packaged cigarettes, the following steps are specifically included. Refer to Figure 5 :

[0047] (1) The strip-packaged cigarette is wrapped with transparent paper. First, the two side ends of the strip-packaged cigarette are folded. After the two ends are folded and ironed, pre-ironing and dot-ironing treatments are carried out on the long side ironing position. The forms of pre-ironing and dot-ironing can ensure that the transparent paper does not come apart during the folding process at both ends;

[0048] (2)After the transparent paper packaging is folded, the strip-packed cigarettes are conveyed to the strip-pack conveying bottom plate of the ironing device. The strip-packed cigarettes are conveyed to the ironing station through the method of pushing and packing. The moving direction of the strip-packed cigarettes is perpendicular to the position of the long-side buckle, which can effectively prevent the generation of wavy lines, improve the appearance quality of the cigarette packs and strip packs, and iron the long sides of the strip-packed cigarettes.

[0049] That is, after the original equipment completes the transparent paper packaging, due to pre-ironing and spot-ironing at the original long-side ironing position, after the transparent paper packaging is folded, the strip-packed cigarettes 13 are conveyed to the strip-pack conveying bottom plate 5, and the strip-packed cigarettes 13 are conveyed to the Nth cigarette station through the method of pushing and packing. The original equipment mechanism cam drives the power shaft 14 to move, the power shaft 14 drives the swing rod 1 to reciprocate, and through the swing, the soldering iron pressure rod 12 forms a swing with the hole on the push plate 11 as the center. The soldering iron pressure rod 12 rotates the soldering iron plate 17 around the rotation axis of the push plate 11 to form a fixed upper and lower bin with the strip-pack pressing plate 4, and iron the long sides of the transparent paper of the strip-packed cigarettes 13.

[0050] The present invention solves the problems that the transparent paper packaging of cigarette packs is prone to wrinkling and the long sides are ironed into a wavy state, which affects the beauty of cigarette packs and cigarette strips. By adopting the method of first folding and ironing the two end sides and then ironing the long sides, at the original ironing position, changing the ironing of the long-side buckle to the form of pre-ironing and spot-ironing can ensure that the transparent paper does not come loose during the folding of the two ends. After the two ends are folded and ironed, then the long sides are ironed. When ironing the long sides, by changing the structure of the original ironing soldering iron moving in an arc trajectory, the long-side soldering iron makes a linear motion after the mechanical structure is changed, ensuring that the moving direction is perpendicular to the position of the long-side buckle, effectively preventing the generation of wavy lines, and improving the appearance quality of cigarette packs and strip packs.

[0051] The above description of the embodiments is for the convenience of those of ordinary skill in the art to understand and use the invention. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative labor. Therefore, the present invention is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art without departing from the scope of the present invention according to the disclosure of the present invention should be within the protection scope of the present invention.
