Description

Technical Field

[0001] This utility model relates to the field of partial functional structure of cigarette packaging machines, specifically an anti-tumble device for the transverse conveyor belt of the inner frame paper in a cigarette packaging machine. Background Technology

[0002] In one process section of the cigarette packaging machine, after the inner frame paper cutter cuts the inner frame paper strip into individual inner frame papers, the inner frame paper acceleration roller and the upper and lower conveyor belts work together to separate them by a certain distance. After passing through the inner frame paper rejection roller, the inner frame paper is transported to the inner frame paper guide rail (8) by the inner frame paper transverse output device using the conveyor belt (2), and then pushed towards the folding table by two stops on each of the reciprocating mold box. Two types of push rakes of different thicknesses are evenly distributed on the inner frame paper transverse conveyor belt, corresponding to the inner frame paper of the two push guide rails respectively. The inner frame paper transverse conveyor belt, such as Figure 1 As shown, several sensors (4, 6, 10) monitor the inner frame paper as it is fed through the inner liner guide rail (8) to the folding table. Sensors (4, 6) monitor whether the inner frame paper has entered flush with the folding table. If any of the sensors (4, 6, 10) detects that the inner frame paper is not in the correct position or that there is a missing inner frame paper, the machine's electrical control system receives a signal and the machine stops. The operator then uses the handle (5) to flip the unit (7) upwards and checks for any blockage of inner frame paper material. All inner frame paper is then removed from the inner frame paper guide rail (8), and the unit (7) is placed back down. After the machine restarts, cigarette packs without inner frame paper will be discarded.

[0003] Due to quality issues with the inner frame paper itself or equipment malfunctions, clogging of the inner frame paper frequently occurs during operation. When the inner frame paper becomes blocked at the transverse conveyor belt, it subjects the belt to lateral force, causing it to overturn. Furthermore, the distance between the transverse conveyor belt and the stops on the reciprocating die box is small. When the conveyor belt overturns, the stops, which move forward with the reciprocating die box, interfere with the conveyor belt, leading to damage or breakage of the transverse conveyor belt. This increases unplanned downtime and severely restricts the improvement of equipment operating efficiency.

[0004] Existing technology has significant gaps in the guiding and positioning sections on both sides of the inner frame paper transverse conveyor belt. There are no side guides from the edge of the guide rail at the front of the conveyor belt to the inner frame paper brake. This gap corresponds to the position where the reciprocating die box stops at the guide rail push the inner frame paper. This causes the inner frame paper transverse conveyor belt to frequently overturn due to blockage by the inner frame paper at the guide rail, resulting in damage or even breakage from the stops on the forward-moving reciprocating die box. This leads to a much shorter-than-expected service life for the inner frame paper transverse conveyor belt, more frequent unplanned downtime for conveyor belt replacement, and significantly restricts equipment operating efficiency. Summary of the Invention

[0005] To address the problems and shortcomings of the existing technology, the inventors have modified the machine to provide a device that extends the service life of the inner frame paper transverse conveyor belt and reduces unexpected downtime caused by sudden malfunctions. This device is simple in structure, low in cost, and easy to use. Installation only requires drilling and tapping holes in the bracket and securing it with two fixing bolts; minimal maintenance is required during daily use. Position adjustment is simple and convenient; once adjusted, no repeated adjustments are needed even if the conveyor belt or auxiliary materials are replaced. This effectively extends the service life of the inner frame paper transverse conveyor belt, providing strong support for the stable operation of the equipment.

[0006] Specifically, this utility model is implemented as follows: an anti-tipping device for the transverse conveyor belt of the inner frame paper in a cigarette packaging machine, installed on the bracket of the inner frame paper conveying mechanism, includes: mounting screw holes provided on the bracket of the inner frame paper conveying mechanism for installing fixing bolts; fixing bolts are used to pass through the anti-tipping component and screw into the mounting screw holes for fixing and positioning the anti-tipping component; the anti-tipping component has an H-shaped longitudinal section, including a hanging plate part and a limiting guide part, the hanging plate part is used to pass through the mounting screw holes through the fixing bolts, and the limiting guide part is parallel to the conveying direction of the transverse conveyor belt of the inner frame paper and has two baffles, so that the transverse conveyor belt of the inner frame paper passes between the two baffles, for limiting the tilting and tipping of the transverse conveyor belt of the inner frame paper.

[0007] Furthermore, the fixing bolts are located between the edge of the guide rail at the front end of the conveyor belt and the inner frame paper brake, and there are two of them, which are set parallel to the transverse conveyor belt direction of the inner frame paper.

[0008] Furthermore, the limiting guide portion includes a top surface and two side guards, forming a guide groove structure. The spacing between the side guards is wider than the width of the inner frame paper transverse conveyor belt, and a gap of 2-4 mm is maintained between them and the inner frame paper transverse conveyor belt. The distance between the inner frame paper transverse conveyor belt and the top surface is maintained between 4-7 mm.

[0009] Furthermore, the mounting plate has a horizontal mounting groove for the fixing bolts to pass through; one end of the mounting groove is open.

[0010] Furthermore, it also includes adjusting shims, of which there are several, which can be passed through the bracket surface of the inner frame paper conveying mechanism and the anti-overturning component by fixing bolts, and are used to adjust the centering of the anti-overturning component relative to the inner frame paper conveying belt.

[0011] Furthermore, the adjusting shim can be annular or have a shape consistent with the longitudinal cross-sectional shape of the anti-rollover component.

[0012] Furthermore, the inner edges of the two ends of the limiting guide portion are chamfered.

[0013] Furthermore, the mounting screw holes are vertically arranged oblong holes.

[0014] The working principle of this utility model is as follows: This utility model is installed on the bracket of the inner frame paper conveying mechanism. Two fixing bolts pass through the anti-overturning component (whose longitudinal cross-section is H-shaped, including a hanging plate and a limiting guide portion) and are then screwed into the mounting bolt holes, thereby fixing and positioning the anti-overturning component. The fixing bolts are positioned between the edge of the guide rail at the front end of the conveyor belt and the inner frame paper brake, and are parallel to the transverse conveyor belt direction of the inner frame paper, ensuring that the anti-overturning component can accurately act on the conveyor belt area prone to problems. The limiting guide portion of the anti-overturning component is parallel to the conveying direction of the transverse conveyor belt of the inner frame paper, and has two guard edges, forming an overall guide groove structure. This allows the transverse conveyor belt of the inner frame paper to pass smoothly within it, while also providing a blocking and limiting force from the side. When the conveyor belt experiences abnormal overturning due to blockage or other reasons, the space for its edge to turn upwards is simultaneously restricted and constrained by the guard edges and the top surface, preventing it from overturning smoothly. Therefore, the distance between the top surface and the conveyor belt is particularly important; the height cannot be too high. The guide groove structure prevents the conveyor belt from overturning, thus protecting it from damage by the reciprocating mold box blocks. Equipped with adjusting shims, several shims can be installed between the bracket surface and the anti-tipping component using fixing bolts. These shims can be circular or have the same longitudinal cross-sectional shape as the anti-tipping component. They are used to adjust the centering of the anti-tipping component relative to the inner frame paper conveyor belt, ensuring that the inner frame paper conveyor belt is centered within the anti-tipping component, with its edges not contacting the side guards, and is in the optimal limiting and guiding position. When it is necessary to adjust the height gap between the top surface and the inner frame paper conveyor belt, the mounting screw holes can be set to vertical oblong holes, allowing for vertical adjustment of the relative height of the anti-tipping component.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] (1) Extended service life of the conveyor belt: The limiting and guiding part of the anti-overturning component limits the transverse conveyor belt of the inner frame paper. The two side guards, top surface and reasonable spacing between the anti-overturning component and the conveyor belt effectively limit the tilting and overturning of the conveyor belt caused by the blockage of the inner frame paper, and prevent it from being scratched or even broken by the blocks on the forward-moving reciprocating mold box. This effectively extends the service life of the transverse conveyor belt of the inner frame paper and reduces the number of times the conveyor belt needs to be replaced due to unplanned sudden shutdown. The equipment can maintain a more stable and continuous operating state. Correspondingly, the overall operating efficiency of the equipment is greatly improved, avoiding production interruptions caused by conveyor belt failure and ensuring the smoothness of the cigarette packaging machine production process.

[0017] (2) Flexible operation: The equipped adjustment shims can be installed between the bracket surface and the anti-overturning component by fixing bolts. Their various shapes (circular or consistent with the longitudinal section shape of the anti-overturning component) can meet different adjustment needs, making it convenient to adjust the centering of the anti-overturning component relative to the inner frame paper conveyor belt, and ensuring that the conveyor belt is in the optimal limit guide position. On the other hand, the mounting screw holes are set as vertically arranged waist-shaped holes, which allows the relative height of the anti-overturning component to be adjusted vertically. It is convenient to adjust the height distance between the anti-overturning component and the inner frame paper conveyor belt according to the actual situation, further enhancing the applicability and flexibility of the device.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Example 1: The usage process of an anti-tumble device for the transverse conveyor belt of the inner frame paper in a cigarette packaging machine:

[0028] Before installation, confirm the structure of the bracket 20 of the inner frame paper conveying mechanism and the space position between the edge of the front guide rail of the conveyor belt and the inner frame paper brake. Prepare the corresponding installation tools, such as drilling equipment, taps, etc., as well as the required fixing bolts 22, adjusting shims 27 and other parts.

[0029] Based on the dimensions and installation requirements of the mounting plate portion 24 of the anti-rollover component 23, determine the position of the mounting screw holes 21 on the bracket 20, drill the holes using drilling equipment, and then tap them to ensure that the mounting screw holes 21 meet the requirements. If the mounting screw holes 21 are designed as vertically arranged oblong holes, ensure their dimensional accuracy and vertical direction accuracy. When drilling, in the vertical position, try to install the device as close to the top as possible to maximize its limiting and guiding function, and also facilitate subsequent position adjustments so that it is positioned as close as possible to the reciprocating mold box stop. In the horizontal position, ensure that the right edge of the guide groove is flush with the edge of the lower guide plate.

[0030] Align the horizontal mounting groove 26 of the hanging plate portion 24 of the anti-rollover component 23 with the bracket 20, where one end of the mounting groove 26 is open to facilitate horizontal adjustment of the relative position; align it with the pre-machined mounting screw holes 21 on the bracket 20.

[0031] During installation, check if the transverse conveyor belt of the inner frame paper is centered in the guide groove of the device. If it is not centered, the transverse position of the guide groove can be adjusted by adding adjusting shims 27 or by filing. After slightly loosening the two fixing screws of the device, lower the conveyor belt bracket 20 and adjust the position of the anti-overturning device in the transverse position so that it is as close as possible to the right side of the reciprocating mold box stop.

[0032] After the initial installation is completed, check the positional relationship between the anti-overturning component 23 and the inner frame paper conveyor belt 2. If it is necessary to adjust the centering of the anti-overturning component 23, select an appropriate shape, such as a circular ring or an adjusting shim 27 that matches the longitudinal cross-sectional shape of the anti-overturning component 23. Insert the adjusting shim 27 through the fixing bolt 22 and place it between the bracket 20 and the anti-overturning component 23. Increase or decrease the number of adjusting shims 27 according to the actual situation so that the inner frame paper conveyor belt 2 is centered within the limiting guide portion 25 of the anti-overturning component 23, that is, the two edges of the conveyor belt will not contact the side guard.

[0033] If it is necessary to adjust the height distance between the top surface and the inner frame paper conveyor belt 2, take advantage of the vertically arranged waist-shaped hole design of the mounting screw hole 21. Loosen the fixing bolt 22, move the anti-overturning component 23 vertically along the waist-shaped hole to the appropriate height position, and then tighten the fixing bolt 22 again to ensure that the distance between the top surface and the conveyor belt is maintained between 4-7mm, and a gap of 2-4mm is maintained between the side guard and the conveyor belt. The guide groove formed by the two sides and the bottom plate restricts the position of the inner frame paper transverse conveyor belt to prevent it from overturning due to blockage by the inner frame paper. The width of the guide groove is slightly larger than the width of the transverse conveyor belt, which can provide a good limiting and guiding effect on its operation without affecting the operation of the conveyor belt. The depth of the guide groove is determined by measuring the actual position of the transverse conveyor belt during operation. The purpose is to ensure that there is a certain gap between the running conveyor belt and the bottom of the guide groove, and a certain gap between the guide groove and the bottom plate to ensure that they do not interfere with each other. The two sides of the guide groove have a large chamfer design at the part where the conveyor belt enters, forming a trumpet shape. This is to prevent the conveyor belt from interfering with it due to jumping when entering the guide groove.

[0034] During the normal operation of the cigarette packaging machine, regularly check whether the anti-tilting component 23 is loose and whether the fixing bolts 22 show any signs of loosening. If they are loose, tighten them in time.

[0035] Observe the operation of the transverse conveyor belt of the inner frame paper within the limiting guide part 25 of the anti-overturning component 23, and check for any abnormal jamming or friction. If any problems are found, stop the machine in time to troubleshoot and ensure that the device is always in good working condition, continuously play its role in limiting the tilting and overturning of the conveyor belt, and ensure the stable operation of the equipment.

[0036] After the inner frame paper anti-tilting device is installed, its actual effect is tested by simulating inner frame paper blockage. When the inner frame paper is conveyed to the transverse conveyor belt by rotating the machine, the conveyor belt support 20 is lifted upwards, the inner frame paper is placed at an angle, and then the conveyor belt support 20 is lowered. The machine is then rotated again to block the inner frame paper at the transverse conveyor belt. It is observed that when the inner frame paper on the transverse conveyor belt overturns, the limiting effect of the guide plates on both sides of the device stops the two sides of the conveyor belt, greatly reducing the overturning amplitude. The distance between the inner frame paper and the stop block on the reciprocating mold box is always kept within a safe and non-interfering range, effectively protecting the transverse conveyor belt.

[0037] The anti-overturning device for the inner frame paper transverse conveyor belt was installed and put into use in the FOCKE.FX unit in October 2024. Currently, four out of six units are in use. A survey and statistical analysis of the performance of these four units after installation revealed the following: Unit #1 experienced frequent blockages of the inner frame paper during startup and shutdown due to quality issues with the inner frame paper auxiliary material and problems with the inner frame paper removal elbow blowing procedure. This resulted in severe damage to the inner frame paper transverse conveyor belt, requiring replacement on average every two days before the device was installed. After three months of operation following the installation of the anti-overturning device, no damage has been found to the transverse conveyor belt. Other units have also not experienced any further transverse conveyor belt damage or breakage since its implementation. This device effectively improves the service life of the inner frame paper transverse conveyor belt, significantly reducing the frequency of unplanned sudden shutdowns and conveyor belt replacements, thus ensuring equipment operational stability.

[0038] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
