Description

Technical Field

[0001] This invention belongs to the field of cigarette processing technology, and specifically relates to a water-tip paper glue device with an adjustable glue outlet. Background Technology

[0002] The tipping paper glue applicator is a key piece of equipment in cigarette rolling and splicing units, used to apply glue during the splicing process between the filter tip and the tipping paper. The uniformity of glue application and the precise control of glue dispensing directly affect the splicing quality of cigarettes and the product qualification rate.

[0003] Our team's earlier patent applications, CN117016858A and CN120360304A, provide a highly efficient solution for adhesive coating processes through an innovative "integrated adhesive return-cleaning" technology system. The core of this device lies in its closed-loop fluid control system, which integrates the traditionally dispersed adhesive return, cleaning, and coating functions into a single unit through integrated design. This technology primarily relies on the socketed structure between the adhesive holder and the fixed distribution disc. The fixed distribution disc contains a dense network of axial pipes, forming multi-stage fluid distribution channels. During coating operations, the adhesive is output through the axial pipes of the distribution disc. In non-operational phases, the system recovers excess adhesive through negative pressure backflow, while simultaneously using a cleaning medium to circulate and flush within the same pipes, significantly reducing the risk of adhesive curing and clogging.

[0004] However, with the increasing demands for product quality and consumption in cigarette manufacturing, the aforementioned technical solution, while feasible, has certain limitations. The glue output of this solution is controlled by a fixed distribution disc pipeline, which is a macro-fluid control method. The width of the glue outlet is fixed, making online continuous adjustment impossible and lacking the ability to control the glue output with higher precision. When it is necessary to adjust the glue output to adapt to different specifications of tipping paper or different production speeds, it is necessary to stop the machine to replace parts or adjust the entire distribution system, affecting production efficiency.

[0005] Furthermore, traditional rubber roller coating technology uses a fixed groove depth for the control roller, which means the glue output cannot be adjusted in real time during operation. The fixed groove depth also results in an unchangeable glue layer thickness, making it difficult to meet the production needs of products with different specifications. Moreover, cleaning requires disassembling the rubber roller, making maintenance inconvenient.

[0006] Therefore, there is an urgent need to design a cork glue device that can continuously adjust the glue output online, has high control precision, and is easy to clean and maintain. Summary of the Invention

[0007] The present invention aims to provide a cork glue device with an adjustable glue outlet, which solves the problems of low glue dispensing accuracy, fixed glue outlet width that cannot be continuously adjusted online, and inconvenient cleaning and maintenance of existing cork glue devices.

[0008] To achieve the above objectives, this invention provides a glue applicator for cork paper with an adjustable glue outlet, comprising a glue inlet unit, a glue roller that can be angled and deflected by a driver-1, and a cleaning water tank disposed below the glue roller. A glue outlet unit is disposed on the inner circumference of the glue roller, comprising a fixed block and a movable adjusting block. The gap between the adjusting block and the fixed block forms the glue outlet, the width H of which is adjustable. A driver is provided for adjusting the gap width H between the fixed block and the adjusting block. The glue roller has a first position and a second position: in the first position, the glue outlet faces downwards and engages with the cork paper for glue application; in the second position, the glue outlet enters the cleaning water tank for cleaning. This embodiment, through online continuous adjustment of the glue outlet width, ensures the accuracy of matching and tracking between the output glue layer thickness and the cork paper speed, reduces the impact of fluctuations in the glue layer thickness on the cork paper on product quality, and improves equipment efficiency and product quality stability.

[0009] Furthermore, the glue roller is equipped with electrical contacts, which are connected to an external control signal via a fixedly mounted electrical slider. When the glue roller is in the first position, the electrical slider and the electrical contacts are in contact, making the gap width H adjustable, thus adjusting the glue outlet width H. When the glue roller deflects to the second position, the electrical slider and the electrical contacts are disconnected, de-energizing the driver and making the gap width H non-adjustable.

[0010] Furthermore, the electrical contacts are located on the outer circumferential surface of the rubber roller. When the rubber roller deflects to the first position, the electrical slider abuts against the electrical contacts radially.

[0011] Furthermore, electrical contacts are located on the end face of the rubber roller. When the rubber roller deflects to the first position, the electrical slider abuts against the electrical contacts axially.

[0012] Furthermore, the width H of the dispensing nozzle is 0.01mm to 1.5mm.

[0013] Furthermore, the driver includes driver 2 and transmission assembly, with driver 2 driving the adjustment block to move through transmission assembly.

[0014] Furthermore, the transmission assembly includes a lead screw, which engages with a screw hole on the adjusting block to convert rotary motion into linear motion.

[0015] Furthermore, one end of the adjusting block deflects around the pivot point to change the gap width H between it and the fixed block.

[0016] Furthermore, the transmission assembly includes a connecting rod, which drives the adjusting block to rotate and deflect.

[0017] Furthermore, the transmission assembly includes a worm gear and a sliding groove, which drives the adjusting block to move or change angle along the sliding groove.

[0018] Furthermore, it also includes driver-1, which drives the rubber roller to deflect between the first position and the second position. Driver-1 and driver-2 are stepper motors or servo motors.

[0019] Technical effects: The glue outlet width is continuously adjustable online with high control precision. This invention uses the gap between the fixed block and the adjusting block to form an adjustable glue outlet. The gap width H (0.01mm to 1.5mm) is precisely controlled by the driver, achieving sub-millimeter-level precise control of the glue dispensing volume. This overcomes the shortcomings of existing technologies where fixed pipes or grooves cannot be adjusted online.

[0020] It features dual-mode switching for both gluing and cleaning, with a high degree of functional integration. The glue roller switches between a first position (glueing mode) and a second position (cleaning mode) by tilting its angle. When the glue roller tilts to the second position, the glue outlet automatically enters the cleaning water tank for cleaning without disassembling the equipment. Furthermore, the electrical contacts automatically disconnect as the glue roller tilts, ensuring the drive is powered off safely during cleaning.

[0021] Electrical control enables automated adjustment. Through the contact between the electrical slider and electrical contacts, an external control signal can be connected to the driver when the glue roller is in the first position, realizing remote automated adjustment and control of the glue outlet width.

[0022] Multiple transmission methods are available to suit different needs. The transmission components can adopt various methods such as screw drive, connecting rod drive, or worm gear drive, which can be flexibly selected according to different models of coiling units and space layouts, making it widely applicable.

[0029] like Figures 1a to 1e As shown, this embodiment provides a cork paper glue applicator with an adjustable glue outlet. The applicator includes a glue inlet unit, a glue roller that can be angled and deflected by a driver-1, and a cleaning water tank located below the glue roller. A glue outlet unit is fixedly installed on the inner circumference of the glue roller. The glue outlet unit is connected to the glue inlet unit through a glue channel inside the glue roller, and outputs glue to coat the surface of the cork paper during operation.

[0030] The glue dispensing unit includes a fixed block, an adjusting block, a driver 2, and a transmission assembly. The fixed block is fixedly mounted on the inner circumference of the glue roller via a fixing screw hole. The gap between the adjusting block and the fixed block along the axis of the glue roller forms the glue dispensing port, the width of which is H, ranging from 0.01 mm to 1.5 mm. The driver 2 is controlled by an external control signal and drives the adjusting block to move via the transmission assembly, thereby adjusting the gap width H between the fixed block and the adjusting block.

[0031] Electrical contacts are provided on the outer circumference of the rubber roller, which are connected to an external control signal via a fixed electrical slider. When the rubber roller deflects to the first position (e.g., Figure 1b When (as shown), the electric slider makes contact with the electrical contact and conducts electricity. External control signals are connected through the electric slider and electrical contact, thereby controlling the driver 2 and adjusting the glue outlet width H. The glue outlet of the glue dispensing unit faces downwards to cooperate with the cork paper for glue application. When the glue roller deflects to the second position (as shown), Figure 1c When the electrical slider disconnects from the electrical contact (as shown), the glue outlet of the glue dispensing unit enters the cleaning water tank for cleaning, and the driver 2 is de-energized.

[0032] Driver 1 is used to drive the rubber roller to deflect between a first position and a second position. Driver 1 and driver 2 are stepper motors or servo motors. Driver 2 is located on one side of the fixed block and is connected to the adjusting block via a transmission assembly. Figure 2a , Figure 2b As shown, in this embodiment, the driver 2 operates in a rotary motion mode, and the transmission component uses a lead screw drive. The driver 2 drives the lead screw to rotate, and the lead screw engages with a fixed screw hole on the adjusting block, converting the rotary motion into linear movement of the adjusting block. Figure 2c , Figure 2d As shown, the transmission assembly also includes a rotating fulcrum, and one end of the adjusting block deflects around the rotating fulcrum to change the gap width H between the adjusting block and the fixed block. Example

[0033] This embodiment is basically the same in structure as Embodiment 1, except that the electrical contacts are located on the end face of the rubber roller, such as... Figure 1d , Figure 1eAs shown. When the rubber roller deflects to the first position, the electric slider abuts against the electric contact in the axial direction to achieve conduction; when the rubber roller deflects to the second position, the electric slider separates from the electric contact in the axial direction. Example

[0034] This embodiment is basically the same in structure as Embodiment 1, the difference being: Figure 2e As shown, the driver 2 operates in a linear motion mode, and the transmission component includes a connecting rod. The driver 2 drives the connecting rod to move, and the connecting rod causes the adjusting block to rotate and deflect, thereby changing the width H of the dispensing nozzle. Example

[0035] This embodiment is basically the same in structure as Embodiment 1, the difference being: Figure 2f As shown, the driver 2 operates in a rotary motion mode, and the transmission components include a worm gear and a sliding groove. The worm gear converts the rotary motion into linear motion, driving the adjusting block to move along the sliding groove or change its angle, thereby changing the width H of the dispensing nozzle. Example

[0036] This embodiment has a structure that is basically the same as that of embodiment 1, except that the driver 2 is located on the side of the rubber roller, rather than on the side of the fixing block.
