Description

Technical Field

[0001] This utility model relates to the field of tobacco equipment technology, and in particular to a device for pre-coating adhesive for cigarette box creases. Background Technology

[0002] Currently, the application of adhesive to cigarette boxes is generally done semi-automatically. The cigarette boxes are placed manually in their designated positions and their positions are manually adjusted to ensure accurate entry into the adhesive application equipment. However, manual operation often requires adjusting only a few boxes simultaneously and pressing them down; otherwise, uneven pressure can cause the boxes to shift position upon entering the equipment, leading to adhesive failure.

[0003] In practical use, it was found that the existing cigarette box gluing device applies glue to the two sides that need to be folded and fixed after the cigarette box has been folded and cut. However, because the cigarette box surface has some paper scraps and other impurities after folding and cutting, these impurities are carried into the glue container when applying glue to the two sides. This results in impure glue inside the container. Furthermore, when paper scraps and other impurities adhere to the gluing wheel, they come into contact with the glue in the container again, resulting in less glue adhering to the areas where the impurities are stuck. This leads to uneven glue application at these impurity areas, affecting the subsequent secure bonding of the two sides of the cigarette box. Consequently, the cigarette box becomes substandard, requiring re-gluing or even scrapping, increasing production costs and reducing production efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a pre-coating device for cigarette box creases, so as to solve the technical problem mentioned in the background art that when applying glue to cigarette boxes, impurities on the cigarette box are easily adhered to the glue roller, resulting in uneven glue application.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-coating device for cigarette box creases, comprising a control body, a transmission mechanism on the control body, the transmission mechanism including a drive shaft and a driven shaft rotatably mounted on the control body, two sets of cleaning mechanisms on the control body, the cleaning mechanism including a glue bucket and a glue wheel, a rotatable transmission shaft on the control body, a brush on the transmission shaft, and the transmission shaft connected to the driven shaft via a transmission belt.

[0006] Preferably, the transmission mechanism includes a fixed plate, on which a plurality of pulleys are rotatably mounted, and the pulleys are connected to the drive shaft via the friction belt.

[0007] Preferably, the control body is provided with two rotatable lead screws, each of the glue barrels is provided with a connector, the connector is threadedly connected to the corresponding lead screw, and a guide post is fixedly provided on the control body, the connector is slidably connected to the guide post.

[0008] Preferably, each of the connecting parts is rotatably provided with a pressure roller, and the outside of the rubber roller is provided with an elastic element of flexible anti-corrosion material. The height of the brush is higher than the height of the elastic element, and the rubber roller is rotatably connected to the rubber bucket.

[0009] Preferably, the feeding end of the control body is provided with a placement mechanism, which includes a fixed frame fixed on both sides of the control body, a support plate fixed on the fixed frame, and a tray fixedly connected to the support plate via a connecting column.

[0010] Preferably, the control body is provided with a straightening mechanism located at the feed end. The straightening mechanism includes multiple fixed rods fixed to the control body. Two pneumatic components are slidably connected to the fixed rods. An extrusion plate is fixedly provided at the telescopic end of the pneumatic component. The control body is provided with a reciprocating screw located between the two fixed rods. The helical directions on both sides of the reciprocating screw are opposite. Both sides of the reciprocating screw are threadedly connected to the pneumatic components.

[0011] The beneficial effects of this utility model are:

[0012] 1. By driving the brush to rotate through the driven shaft, and positioning the brush before the cigarette box passes the rubber roller, with the width of the brush greater than the width of the rubber roller and the elastic element, and the centers of both on the same horizontal line, the brush can accurately clean the areas of the cigarette box that need to be coated with glue. This prevents paper scraps and other impurities on the cigarette box from adhering to the rubber roller, which would cause uneven glue application to the cigarette box at the impurity-adhesive areas on the subsequent rubber roller. This ensures uniform glue application and reliable fixation of the cigarette box's fixed edges. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Currently, the application of adhesive to cigarette boxes is generally done semi-automatically. The cigarette boxes are placed manually in their designated positions and their positions are manually adjusted to ensure accurate entry into the adhesive coating equipment. However, manual operation often only allows for simultaneous adjustment of a few boxes. When there are many boxes, it becomes difficult to adjust their positions, and the boxes need to be pressed down to prevent uneven pressure. This can cause the boxes to shift during entry into the coating equipment, leading to coating failure.

[0024] To resolve the above technical issues, please refer to Figures 1 to 7As shown, an embodiment of the present invention provides a pre-coating device for cigarette box creases, comprising a control body 1, a transmission mechanism 2 on the control body 1, a drive shaft 201 and a driven shaft 202 rotatably mounted on the control body 1, two cleaning mechanisms 3 on the control body 1, each cleaning mechanism 3 including a glue tank 301 and a glue wheel 302, the transmission mechanism 2 including a fixed plate 203, on which a plurality of pulleys 204 are rotatably mounted, the pulleys 204 being connected to the drive shaft 201 via friction belts 205, two rotatable lead screws 308 on the control body 1, each glue tank 301 having a connector 305 threadedly connected to the corresponding lead screw 308, a guide post fixedly mounted on the control body 1, the connector 305 being slidably connected to the guide post, and a pressure roller 306 rotatably mounted on each connector 305, the glue wheel 302 being... The control body 1 is equipped with a flexible, corrosion-resistant elastic element 307. The rubber wheel 302 is rotatably connected to the rubber bucket 301. The feeding end of the control body 1 is equipped with a placement mechanism 4. The placement mechanism 4 includes a fixed frame 401 fixed on both sides of the control body 1. A support plate 402 is fixed on the fixed frame 401. A support plate 403 is fixedly connected to the support plate 402 via a connecting column. The control body 1 is equipped with a straightening mechanism 5 located at the feeding end and above the placement mechanism 4 and the transmission mechanism 2. The straightening mechanism 5 includes multiple fixed rods 501 fixed on the control body 1. Two pneumatic components 502 are slidably connected to the fixed rods 501. A pressing plate 503 is fixedly provided at the telescopic end of the pneumatic component 502. The control body 1 is equipped with a reciprocating screw 504 located between the two fixed rods 501. The spiral directions on both sides of the reciprocating screw 504 are opposite. Both sides of the reciprocating screw 504 are threadedly connected to the pneumatic component 502.

[0025] In use, the cigarette box is first placed on the tray 403 of the placement mechanism 4. Then, the control body 1 controls the extension and retraction of the pneumatic component 502 of the alignment mechanism 5, so that the extrusion plate 503 extrudes the edge of the cigarette box, thereby aligning the cigarette box as a whole. When the cigarette box enters, it only needs to pass through the upper part of the cigarette box to achieve the extrusion effect, so that the position of the cigarette box when it enters the transmission mechanism 2 is more accurate and the force is more uniform, reducing the error and uneven force during manual adjustment. The reciprocating screw 504 is used to adjust the position of the pneumatic component 502 and the distance between the two pneumatic components 502 to suit cigarette boxes of different widths.

[0026] Furthermore, the side of the pallet 403 closest to the transmission mechanism 2 is a downward inclined surface. The control body 1 is provided with a vertical plate 505 to support the downward inclined tobacco box. The bottom of the vertical plate 505 is slightly greater than the thickness of the tobacco box than the distance between the bottom of the transmission mechanism 2 and the tobacco box, so that only one tobacco box can be carried away by the friction belt 205 at the same time. The power source of the straightening mechanism 5 and the transmission mechanism 2, as well as the control body 1 and its connection method, all adopt existing technologies and will not be described in detail here. Any method in the existing technology can be used to implement them.

[0027] Furthermore, the cigarette box is positioned to contact the friction belt 205, causing the friction belt 205 to move the cigarette box closer to the rubber wheel 302. After the cigarette box moves a certain distance towards the rubber drum 301, the bottom of the cigarette box is inserted between the pressure roller 306 and the rubber wheel 302. The rotation of the rubber wheel 302 and the pressure roller 306 can drive the movement of the cigarette box, or a motor or other drive mechanism can be added. The drive shaft 201 of the transmission mechanism 2 is driven by a motor, which is electrically connected to the control body 1. The driven shaft 202 can be connected to the drive shaft 201 via a connecting belt. None of the above technologies are shown in the figure; any method that can achieve this action can be used.

[0028] The control body 1 is equipped with multiple support plates corresponding to the friction belt 205, so that the bottom of the smoke box is supported when the smoke box passes through. The positions of the adhesive on both sides of the smoke box can accurately enter between the pressure roller 306 and the rubber roller 302. It is not shown in the figure, and this technology is existing technology and will not be described in detail here. If it is necessary to link with other equipment, a corresponding matching mechanism can also be used here, which will not be described in detail here. The specific situation depends on the actual use.

[0029] The roller 302 rotates and continuously drives the glue in the glue tank 301 to adhere to the elastic element 307 of the roller 302. A liquid level sensor is installed inside the glue tank 301 and is electrically connected to the control body 1. An external liquid supply device is installed to supply glue to the glue tank 301. This liquid supply device is electrically connected to the control body 1. When the glue in the glue tank 301 decreases to a certain level, the liquid level sensor sends a signal to the control body 1. The control body 1 controls the liquid supply device to add glue to the glue tank 301. (Not shown in the figure) This technology uses existing technology and will not be described in detail here. This allows the glue to be applied to the two sides of the cigarette box that need to be bonded and fixed. At the same time, the pressure roller 306 can provide a certain amount of pressure so that the glue can be applied to the sides of the cigarette box relatively evenly, thereby completing the glue application operation of the cigarette box.

[0030] With the configured rubber roller 302, elastic element 307, and pressure roller 306, the glue application process for the tobacco box is automatically completed as it passes through. The continuous rotation of the rubber roller 302 and the adhesion of glue to the elastic element 307 to the sides of the tobacco box ensure that the glue is applied evenly. The pressure roller 306 provides a certain squeezing and pushing effect, making the glue application more uniform. The extrusion plate 503 squeezes the edge posts of the tobacco box, aligning the entire tobacco box. As a result, when the tobacco box enters, it only needs to pass through the upper part of the tobacco box to achieve the squeezing effect, making the tobacco box enter the position more accurately and the force more even, reducing the error and uneven force during manual adjustment.

[0031] Example 2

[0032] In practical use, it was found that the existing cigarette box gluing device applies glue to the two sides that need to be folded and fixed after the cigarette box has been folded and cut. However, due to the presence of paper scraps and other impurities on the surface of the cigarette box after folding and cutting, the glue roller 302 picks up these impurities when applying glue to the two sides. This impurities are then carried into the glue container 301, resulting in impure glue. Furthermore, when paper scraps and other impurities adhere to the glue roller 302, they come into contact with the glue in the container again, resulting in less glue adhering to the areas where impurities are present. This leads to uneven glue application at these impurity sites, affecting the subsequent secure bonding of the two sides of the cigarette box. Consequently, the cigarette box may fail to meet quality standards, requiring re-gluing or even scrapping, increasing production costs and reducing production efficiency.

[0033] To solve the above technical problems, based on the above embodiments, please refer to... Figures 1 to 7 As shown, the control body 1 includes a rotatable transmission shaft 309. A brush 303 is mounted on the transmission shaft 309. The center of the brush 303 is aligned with the center of the corresponding elastic element 307. The width of the brush 303 is greater than the width of the elastic element 307. The transmission shaft 309 is connected to the driven shaft 202 via a transmission belt 304. The height of the top of the brush 303 is higher than the height of the top of the elastic element 307.

[0034] Based on the above embodiments, during use, when the cigarette box passes between the drive shaft 201 and the driven shaft 202, the driven shaft 202 can be connected to the drive shaft 201 via a connecting belt, while the drive shaft 201 is driven by a motor (not shown in the figure). The friction belt 205 drives the cigarette box to move continuously toward the glue bucket 301. The position of the glue bucket 301 can be adjusted by the lead screw 308, thereby adjusting the position of the glue wheel 302 according to different glue application positions of the cigarette box, thus adapting to various different glue application positions. The drive of the lead screw 308 can be implemented in any way of the prior art, which will not be described in detail here. At this time, the driven shaft 202 drives the corresponding drive shaft 309 to rotate through two transmission belts 304, and the drive shaft 309 drives the brush 303 to rotate.

[0035] The top height of the brush 303 is slightly higher than the top height of the rubber wheel 302. This allows the brush 303 to clean the area on the bottom of the cigarette box that needs to be coated with adhesive when the cigarette box passes over it. This prevents the rubber wheel 302 from accumulating too many impurities when applying adhesive to the bottom of the cigarette box, which would result in impure adhesive. It also prevents uneven adhesive application when applying adhesive to areas with impurities on the rubber wheel 302, which could lead to the cigarette box not being securely fixed. The brush 303 is made of a flexible material and will not scratch the cigarette box. The axis of the brush 303 is horizontal and at the same height as the axis of the rubber wheel 302, and the width of the brush 303 is greater than the width of the rubber wheel 302, thus ensuring the accuracy of the cleaning position.

[0036] While the rubber wheel 302 rotates, a protective net 310 is provided at the connection between the rubber wheel 302 and the glue bucket 301. The height of the protective net 310 is lower than the height of the top of the rubber wheel 302. This is to prevent the smoke box from rubbing against the surrounding parts. If fine debris is generated, it will fall into the glue bucket 301 through the protrusion of the rubber wheel 302, causing impurities in the glue in the glue bucket 301.

[0037] The driven shaft 202 drives the brush 303 to rotate, and the position of the brush 303 is set before the cigarette box passes the rubber wheel 302. The width of the brush 303 is greater than the width of the rubber wheel 302 and the elastic element 307, and the centers of the two are on the same horizontal line and the middle axis is on the same plane. This allows the brush 303 to accurately clean the area of ​​the cigarette box that needs to be coated with glue, avoiding paper scraps and other impurities on the cigarette box from sticking to the rubber wheel 302. This would prevent uneven glue application to the cigarette box at the impurity-adhesive areas of the rubber wheel 302, thus ensuring uniform glue application and reliable fixation of the cigarette box.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
