Description

Technical Field

[0001] This utility model relates to the field of tobacco equipment, specifically to an auxiliary manual capping machine. Background Technology

[0002] In existing carton packaging production lines, top sealing of filled cartons (hereinafter referred to as "cartons") is a crucial process. Currently, automating this process still faces numerous challenges. Traditional sealing equipment is mostly large, fixed structures. These machines are bulky and heavy, requiring significant fixed space and are difficult to move after installation. They cannot flexibly adapt to changes in production workshop layout or be used between different work areas, resulting in a severe lack of flexibility. More importantly, such equipment is typically designed for cartons of specific sizes, with fixed parameters such as conveyor width and adhesive application mechanism stroke. When handling cartons of different lengths, widths, or heights, cumbersome mechanical adjustments or even parts replacements are often required. This not only leads to increased downtime and reduced production efficiency but also makes it difficult for the equipment to meet the flexible packaging requirements of modern logistics with its diverse, small-batch orders. Furthermore, the existing equipment has limited automation. For the sorting and flattening of the top flaps (including side and rear flaps) of cigarette cartons, manual intervention is sometimes still required to ensure the tape is applied smoothly and firmly. This not only increases labor costs but also affects the consistency of sealing quality and operational efficiency. Therefore, there is an urgent need in this field for a more compact, mobile device that can quickly adapt to cigarette cartons of different specifications and achieve efficient, high-quality automated sealing operations to overcome the aforementioned shortcomings of the existing technology.

Detailed Implementation

[0060] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0061] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention.

[0062] As attached Figures 1-10 As shown, this utility model provides an auxiliary manual sealing machine, which is a highly integrated and automated sealing system mainly used for automatically sealing the top of cigarette cartons. The entire device uses a main frame 700 as its core support structure. This main frame 700 is assembled from industrial aluminum profiles using standard corner brackets and special connectors to form a robust rectangular frame. This aluminum profile frame structure ensures sufficient rigidity and stability of the entire device, while achieving lightweight design and facilitating overall movement and positioning. On the main frame 700, four functional modules are systematically integrated according to the logical sequence of cigarette carton processing: conveying, centering and positioning, lid sorting, and adhesive sealing. The modules are coordinated and controlled by an electronic control system based on a programmable logic controller. This electronic control system receives signals from various detection sensors and drives various servo motors, electric push rods and other actuators to act according to a preset program, thereby realizing the fully automated operation from automatic input of cigarette boxes, precise positioning, automatic flattening of the lid to automatic application of adhesive on the top. The equipment is compatible with a power supply of 220V, 10A, with a rated power of ≤2200W. It supports mobile operation and can flexibly adapt to more production application scenarios.

[0063] The conveying system forms the channel for the inflow, operation, and outflow of cigarette boxes, consisting of three functionally distinct roller conveyors: a front conveyor roller 100, an intermediate roller 200, and a rear conveyor roller 800. The front conveyor roller 100 and the rear conveyor roller 800 are mechanically and electrically identical. As movable extension units, they are detachably rigidly connected to the inlet and outlet ends of the intermediate roller 200 via a highly efficient quick-connect locking device. The core operating component of this quick-connect locking device is the roller tensioning handle 103 installed at the end of the first aluminum profile frame 102. When connection is required, the operator accurately inserts the positioning pin at the end of the front conveyor roller 100 or the rear conveyor roller 800 into the corresponding positioning hole at the end of the intermediate roller 200, and then pulls the roller tensioning handle 103 forward. Through the internal linkage mechanism or cam mechanism, the locking pin extends and inserts into the locking hole, thus securely locking the two roller sections together. To achieve rapid electrical connection, male or female connectors for roller conveyor aviation plugs 104 are installed on the side of the first aluminum profile frame 102 near the end, and corresponding female or male connectors are installed on the middle roller conveyor 200. When mechanical docking is completed, the aviation plugs are also inserted, completing the connection of electrical circuits such as motor power and sensor signals. This modular quick-connect design is key to the excellent site adaptability of this equipment. When the production line layout is adjusted or space needs to be saved, the front and rear conveyor roller conveyors 800 can be quickly disassembled. Each section of conveyor roller conveyor is built on an independent first aluminum profile frame 102. Each of the four corners of the bottom of the first aluminum profile frame 102 is equipped with casters 101 with brakes. The rollers are made of wear-resistant materials such as polyurethane and are equipped with foot brakes, allowing each roller conveyor to be easily moved to the required position and reliably fixed. On the first aluminum profile frame 102, a conveyor roller assembly 106 consisting of multiple rollers arranged in parallel is installed through precisely positioned bearing seats. The rollers are typically made of metal tubing coated with rubber or polyurethane to increase friction with the bottom of the cigarette box. The drive system can be either an electric roller design (with the drive motor built into the roller) or an external motor that drives a group of rollers to rotate synchronously via a chain or timing belt. A first positioning detection photoelectric sensor 105 is installed on the side crossbeam of the first aluminum profile frame 102. This photoelectric sensor is preferably a through-beam type, with its transmitter and receiver located on opposite sides of the conveyor roller group 106. The light beam passes through the gap between the rollers; when the cigarette box passes by, it blocks the light beam, generating a positioning signal. The entire side of the first aluminum profile frame 102 is completely covered by a metal roller guard plate 108, which is fixed with screws to effectively prevent personnel from touching the internal moving parts, providing safety protection and dust prevention.In addition, a threaded adjusting bolt 107 is provided at the lower part of the support leg of the first aluminum profile frame 102. The height of this section of the roller line can be finely adjusted by turning the adjusting bolt 107 to ensure a smooth transition with the intermediate roller line 200 and other adjacent equipment.

[0064] The intermediate roller conveyor 200 is a fixed station for performing the core sealing process, requiring higher structural rigidity and stability. It includes a fixed base 201 welded from thick steel plates, which is mounted on the ground via casters with brakes. During operation, the operator depresses the caster brakes to secure the equipment. A second aluminum profile frame 202, serving as the load-bearing structure, is bolted to the top of the fixed base 201. An intermediate roller assembly 203 is precisely mounted on the second aluminum profile frame 202 via bearing seats. At least two adjacent rollers in this intermediate roller assembly 203 are differential-speed electric rollers. These two differential-speed electric rollers are independently controlled by an electronic control system, generating a preset, minute linear speed difference. When the cigarette cartons enter the intermediate roller conveyor 200, this speed difference allows for fine-tuning of the cartons' direction of travel, effectively correcting any deviations during transport and ensuring precise stopping at the adhesive application station set by the blocking component 307. This is crucial for ensuring the accuracy of subsequent adhesive application. A third positioning detection photoelectric sensor 205 is also installed on the intermediate roller conveyor 200 to detect the specific position of the cigarette box within the workstation. A metal intermediate line guard plate 204 is also installed on the side of the second aluminum profile frame 202 to ensure safety.

[0065] The clamping guide device 300 is the core of the entire equipment for centering and positioning, spanning and fixedly installed above the intermediate roller line 200. This device itself also has a frame structure made of aluminum profiles. Two high-precision guide shaft linear bearing assemblies 304 are fixedly installed in parallel on this frame. A pair of clamping guide plates 301, made of wear-resistant engineering plastic or metal plates, are sleeved on the guide shaft linear bearing assemblies 304 via linear bearings, allowing for low-friction, high-precision sliding along the guide shafts. The power source driving the pair of clamping guide plates 301 to move in opposite directions is a clamping servo drive motor 302. The clamping servo drive motor 302 transmits power to the clamping guide plates 301 through a synchronous belt drive mechanism 306. The synchronous belt drive mechanism 306 specifically includes a driving synchronous pulley mounted on the output shaft of the clamping servo drive motor 302, a driven synchronous pulley mounted on the end of one of the guide shafts, and a synchronous belt tensioned between the two pulleys. The synchronous belt is fixedly connected to the clamping guide plates 301 via a connecting block. The control system precisely controls the rotation angle and direction of the clamping servo drive motor 302, thereby driving the two clamping guide plates 301 to move synchronously closer or further apart, thus steplessly adjusting the guide distance between them. This design allows the device to flexibly adapt to various widths of cigarette boxes and forces the cigarette box to always travel along the centerline of the adhesive application mechanism. At the entrance end of the clamping guide device 300, a second positioning detection photoelectric sensor 303 is installed to detect whether the cigarette box has entered its centering area and trigger the distance adjustment program. In addition, the device also integrates a precision blocking assembly 307 to precisely block the cigarette box at a predetermined position before adhesive application. The blocking assembly 307 includes a vertically moving blocking plate 307-1 and a blocking electric push rod 307-2 as a power source. The cylinder of the blocking electric push rod 307-2 is fixed to the frame of the clamping guide device 300 by a bracket, and the end of its piston rod is connected to the blocking plate 307-1 through a connector. The baffle plate 307-1 is mounted on the vertically installed baffle guide shaft 307-4 via a linear bearing, ensuring smooth lifting and lowering. When the cigarette box needs to be blocked, the control system commands the baffle electric push rod 307-2 to extend, pushing the baffle plate 307-1 upward so that its top is above the top surface of the intermediate roller assembly 203, thus blocking the cigarette box. When the adhesive application is complete and release is required, the baffle electric push rod 307-2 retracts, causing the baffle plate 307-1 to descend below the roller surface. To precisely control this process, a proximity switch sensor 307-3 is installed to detect whether the cigarette box has accurately contacted the baffle plate 307-1, and a blocking position detection photoelectric sensor 307-5 is also installed to detect whether the baffle plate 307-1 has risen or fallen to the correct position.

[0066] The adhesive application translation mechanism 400 is a key component for performing the final sealing action. It is mounted on the top crossbeam of the main frame 700 via a robust steel mounting bracket 401 and suspended directly above the intermediate roller conveyor 200. This mechanism requires precise movement in two degrees of freedom: vertical lifting and horizontal translation. The lifting function is achieved by a lifting drive module 402, which is powered by an adhesive application head lifting servo motor 404. The adhesive application head lifting servo motor 404 drives a vertically mounted ball screw to rotate via a coupling. The ball screw nut is fixed to a mounting plate connected to the slider of the lifting linear guide 403. The guide rail portion of the lifting linear guide 403 is vertically fixed to the mounting bracket 401. When the adhesive application head lifting servo motor 404 rotates, the rotational motion is converted into linear motion through the ball screw nut pair, driving the entire upper module to smoothly rise and fall along the lifting linear guide 403, thereby adjusting the height of the adhesive application head to match the cigarette boxes of different heights. The horizontal translation function is achieved by the translation drive module 407, which is mounted on the slider of the lifting drive module 402 via a connecting plate and moves together with the lifting module. The translation drive module 407 is driven by the tape applicator translation servo motor, also employing a ball screw mechanism or synchronous belt drive mechanism, and moves along the horizontally mounted translation linear guide 408. The tape applicator body 409 is finally mounted on the output end of the translation drive module 407 via a bracket. The tape applicator body 409 is a multi-functional device, internally containing a spool for mounting the tape roll, a series of guide rollers for guiding the tape path, and a pressing wheel or scraper that ultimately presses the tape onto the housing. A crucial component is the guide pressing conveyor assembly 410, which is mounted on the front of the tape applicator body 409 via a fixed mounting plate 410-5. This assembly includes a pressing drive motor 410-1, which is preferably a brushless DC motor with a built-in reducer. The output shaft of the pressure drive motor 410-1 is connected to a drive shaft 410-3 via a flexible coupling. Drive pulleys are mounted at both ends of the drive shaft 410-3, and two annular sponge pressure belts 410-2 are respectively fitted onto the drive and driven pulleys at both ends. The sponge pressure belts 410-2 are made of foam material with elastic surface and a high coefficient of friction. When the adhesive application begins, the pressure drive motor 410-1 starts, driving the sponge pressure belts 410-2 to rotate, and its linear speed is strictly synchronized with the conveying speed of the lower intermediate roller 200. In this way, the sponge pressure belts 410-2, while elastically pressing the top of the cigarette box, also provide auxiliary forward conveying force, working together with the bottom roller to clamp the cigarette box for smooth movement, which is crucial for ensuring the flatness of the tape during dynamic application. To ensure the effectiveness of the belt drive, a belt tension adjustment mechanism is provided, which includes a tension arm that can rotate around a pin, with the driven pulley mounted on the tension arm.A belt tension adjustment screw 410-4 is screwed onto a tensioning arm, the end of which rests against a fixed fulcrum on the adhesive applicator body 409. By screwing in or out the adjustment screw 410-4, the angle of the tensioning arm can be changed, thereby adjusting the position of the driven pulley and regulating the belt tension. The adhesive applicator body 409 is also equipped with a tape remaining detection photoelectric sensor 406. This sensor points towards the tape roll; when the tape is almost used up, the sensor detects a signal change and triggers an alarm through the control system to prompt the tape roll to be replaced.

[0067] Side flap clamping devices 500 are symmetrically installed in pairs on the left and right columns of the main frame 700, located above the middle roller line 200 on both sides. Their function is to flatten the side flaps that stand upright on both sides of the top of the cigarette box. The overall lifting of this device is accomplished by the rocker arm lifting module 502. The rocker arm lifting module 502 is driven by the rocker arm lifting servo motor 501, which typically adopts a ball screw structure, and its housing is fixedly installed on the column of the main frame 700. A rocker arm clamping cylinder 506 is connected to the slider of the rocker arm lifting module 502 through a rigid mounting plate. The rocker arm clamping cylinder 506 itself can move along a pair of horizontally installed rocker arm guide rails 507. The guide rails of the rocker arm guide rails 507 are fixed to the mounting plate of the lifting module, and the slider is connected to the cylinder body of the rocker arm clamping cylinder 506. The piston rod of the rocker arm clamping cylinder 506 is connected to the left and right rocker arms 508 at both ends through ball joint hinges. To ensure complete synchronization of the movements of the left and right rocker arms 508, a rigid synchronizing rod is typically used to hinge the connection points of the two rocker arms together. When pressing the cover, the rocker arm lifting module 502 first drives the entire clamping device to descend to a preset height, aligning the left and right rocker arms 508 with the side covers of the cigarette box. Then, the rocker arm clamping cylinder 506 actuates, its piston rod extends, pushing the left and right rocker arms 508 inward around their root hinge points, thereby pressing the side covers flat onto the top of the box. To suppress the inertial vibration of the rocker arms during start-up and stop due to their long cantilever, a shock-absorbing cam follower 504 is provided at the root of the rocker arm. This follower moves within a groove of a fixed rocker arm guide plate 503 with a specific curved profile, converting the linear motion of the cylinder into a smoother rocker arm swing and absorbing impact energy.

[0068] The rear flap bending device 600 is mounted on the main frame 700, located at the rear end of the intermediate roller conveyor 200 along the conveying direction. It is responsible for bending and flattening the rear flaps of the cigarette box. The lifting motion of this device is executed by a swing arm lifting module 602, which is driven by a swing arm lifting servo motor 601 and also uses a ball screw mechanism for precise vertical positioning. A swing arm rotation servo motor 603 is fixedly mounted on the lifting slider of the swing arm lifting module 602 via a motor mounting plate. The output shaft of the swing arm rotation servo motor 603 is connected to a horizontally placed swing arm bending shaft 604 via a high-rigidity diaphragm coupling. The swing arm bending shaft 604 is supported by two deep groove ball bearings mounted on support seats to ensure smooth rotation. Both ends of the swing arm bending shaft 604 are fixedly mounted with bending actuation swing arms 606 via key connections or flanges. These swing arms are typically designed in an L-shape to provide a suitable flap bending lever arm. During operation, the swing arm lifting module 602 first drives the entire device to descend to a suitable height. Then, the swing arm rotation servo motor 603 receives a command and rotates by a preset angle (usually around 90 degrees), driving the swing arm 606 to swing downwards from its waiting position via the swing arm spinning shaft 604, using its end to flatten the rear flap onto the top of the carton. To reduce wear on the carton surface, a freely rotating plastic or rubber pressure roller can be mounted on the end of the spinning arm 606 via a bearing. To ensure the accuracy of the swing arm rotation angle and prevent overtravel damage, a swing arm rotation limit photoelectric sensor 605 is provided. This sensor detects the position of a stop plate installed on the swing arm or shaft, thereby limiting the swing arm's rotation range.

[0069] The automated workflow of this device is as follows:

[0070] All mechanisms are reset to the standby position. The front conveyor roller 100, the middle conveyor roller 200, and the rear conveyor roller 800 are in standby mode.

[0071] The cigarette box is placed on the front conveyor roller line 100, and the conveyor roller assembly 106 rotates to feed it into the equipment. When the cigarette box passes the first positioning photoelectric sensor 105, a signal confirms that it has entered the equipment.

[0072] The cigarette box enters the intermediate roller conveyor 200 and touches the second positioning detection photoelectric sensor 303 at the entrance of the clamping guide device 300. Upon signal triggering, the clamping servo drive motor 302, based on preset or measured box width data, drives a pair of clamping guide plates 301 to move to a suitable distance via the synchronous belt drive mechanism 306, centering the cigarette box in the width direction. Simultaneously, the blocking electric push rod 307-2 of the blocking assembly 307 actuates, pushing the blocking plate 307-1 upward along the blocking guide shaft 307-4, precisely blocking the cigarette box at the adhesive application station. Once the proximity switch sensor 307-3 detects that the cigarette box has reached its position, the intermediate roller conveyor 200 stops operating.

[0073] The swing arm lifting module 602 of the rear cover spinning device 600 descends to the program-set height. Then, the swing arm rotation servo motor 603 starts, driving the spinning execution swing arm 606 to swing downward, flattening the rear cover of the cigarette box.

[0074] The rocker arm lifting module 502 of the side cover clamping device 500 descends to the set height. Then, the rocker arm clamping electric cylinder 506 actuates, moving along the rocker arm guide rail 507, driving the left and right rocker arms 508 to synchronously close inward via a synchronous connecting rod, flattening the two side covers of the cigarette box. Afterward, the swing arm rotation servo motor 603 of the rear cover spinning device 600 reverses, causing the spinning execution swing arm 606 to lift and reset, followed by the rocker arm lifting module 602 rising and resetting.

[0075] The lifting drive module 402 of the adhesive application translation mechanism 400 descends under the drive of the adhesive application head lifting servo motor 404, causing the sponge pressing belt 410-2 of the guide pressing conveyor assembly 410 to contact the top of the cigarette box with a certain pressure. Subsequently, the left and right rocker arms 508 of the side cover clamping device 500 open and return to their original positions. Next, the differential speed electric roller of the intermediate roller line 200 restarts, and at the same time, the pressing drive motor 410-1 of the guide pressing conveyor assembly 410 starts, with both moving at synchronized speeds, jointly driving the cigarette box forward. Simultaneously, the translation drive module 407 of the adhesive application translation mechanism 400, driven by the servo motor, drives the adhesive application head body 409 to move at a uniform speed along the width direction of the cigarette box, pulling out the adhesive tape and smoothly pasting it onto the seam at the top of the box. Throughout the adhesive application process, the adhesive tape balance detection photoelectric sensor 406 continuously monitors the adhesive tape status.

[0076] After the adhesive application is completed, the translation drive module 407 and the lifting drive module 402 of the adhesive application translation mechanism 400 sequentially reset and rise. The blocking electric push rod 307-2 of the blocking component 307 retracts, and the blocking plate 307-1 descends to release the cigarette box. The cigarette box is conveyed to the rear conveyor roller line 800, and is finally removed manually or by subsequent automated equipment, completing one work cycle.

[0077] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
