Description

Technical Field

[0001] This application belongs to the field of cigarette production technology, specifically relating to a glue applicator for bonding filter tip forming paper. Background Technology

[0002] Filter tip forming paper bonding is a key step in cigarette production. It is mainly used to wrap filter material (such as cellulose acetate or paper filter material) in forming paper and to ensure its sealing and structural stability through bonding. This includes bonding forming paper into forming paper and bonding forming paper to filter element.

[0003] The existing glue application device has one hot-apply glue nozzle (top), two middle-line glue nozzles, and one cold-apply glue nozzle at the bottom. The bottom three nozzles are controlled by telescopic valve needles, which requires significant maintenance. Failure to maintain them promptly may result in nozzles failing to extend properly or extending incompletely. The nozzle diameter is small, making them prone to wear. Failure to adjust worn nozzles promptly can cause changes in the forming paper. Currently, a non-contact spiral glue spraying system is used, but this system is expensive, has viscosity requirements (high-viscosity glues cannot be used), and is difficult to clean after shutdown. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a glue application device for bonding filter tip forming paper, which makes the filter tip less prone to wear, reduces maintenance workload, and ensures normal glue application operation.

[0005] This application provides a glue applicator for bonding filter tip forming paper, comprising:

[0006] A mounting bracket mechanism is used to fix the glue applicator;

[0007] A hot melt glue gun, located at the top of the mounting bracket mechanism, is used to apply hot melt glue for bonding the molded paper.

[0008] The forming paper gluing mechanism includes a base at the bottom of the gluing device, two solenoid valves arranged side by side on the base, two conduits connected to the outlets of the two solenoid valves respectively, and a glue nozzle at one end of the base. The two conduits are connected to both sides of the glue nozzle. One end of the glue nozzle has two sets of glue outlet holes, which are used to dispense glue lines for bonding the overlapping parts of the forming paper and glue lines for bonding the forming paper to the filter element, respectively. The inlet of the solenoid valve is connected to an external glue supply system.

[0009] Optionally, the mounting bracket mechanism includes a first X-axis adjustment component for synchronously adjusting the positions of the hot melt glue gun and the forming paper glue applicator. The first X-axis adjustment component includes a first mounting base for fixing the glue applicator, a first lead screw rotatably mounted on the first mounting base, a first slider screwed to the first lead screw, a first support member rotatably connected to the end of the first lead screw away from the first mounting base, and a first guide rod whose two ends are respectively connected to the first mounting base and the first support member and slidably cooperate with the first slider. The first lead screw is rotated by external force.

[0010] Optionally, the first X-axis adjustment assembly further includes a first knob disposed at the end of the first lead screw and rotatably connected to the first support member.

[0011] Optionally, the mounting bracket mechanism further includes a first Y-axis adjustment component for adjusting the hot melt glue gun in the direction perpendicular to the X-axis, so as to adjust the extension amount of the hot melt glue gun. The first Y-axis adjustment component includes a second lead screw, a second slider screwed to the second lead screw, two second support members rotatably connected to both ends of the second lead screw, a second guide rod connected to both ends of the two second support members, and a second mounting seat for mounting the hot melt glue gun. The second lead screw is rotated by external force.

[0012] Optionally, the first Y-axis adjustment assembly further includes a second knob connected to one end of the second lead screw.

[0013] Optionally, the mounting bracket mechanism further includes a second Y-axis adjustment component for adjusting the forming paper gluing mechanism in the direction perpendicular to the X-axis, and a second X-axis adjustment component for adjusting the forming paper gluing mechanism in the direction parallel to the X-axis. The second Y-axis adjustment component is used to adjust the extension amount of the forming paper gluing mechanism, and the second X-axis adjustment component is used to adjust the lateral position of the forming paper gluing mechanism relative to the forming paper. The second Y-axis adjustment component includes a third lead screw, a third slider screwed to the third lead screw, two third support members rotatably connected to both ends of the third lead screw, a third guide rod connected to both ends of the two third support members, and a third mounting base fixedly connected to the first slider. The third lead screw is rotated by external force.

[0014] Optionally, a third knob is provided at one end of the third lead screw.

[0015] Optionally, the second X-axis adjustment assembly includes a fourth lead screw, a fourth slider screwed to the fourth lead screw, two fourth support members rotatably connected to both ends of the fourth lead screw, a fourth guide rod connected to both ends of the two fourth support members, and a fourth mounting base fixedly connected to the third slider. The fourth lead screw is rotated by external force.

[0016] Optionally, a fourth knob is provided at one end of the fourth lead screw.

[0017] Optionally, the nozzle has a symmetrical hollow structure, and the contour area of ​​one end near the base is larger than the contour area of ​​the other end, with the two conduits symmetrically connected to both sides of the nozzle.

[0018] The beneficial effects of this application are that it achieves the application of two sets of adhesive lines (for bonding the overlap of the forming paper and for bonding the forming paper to the filter element) through a single nozzle. The hot melt glue gun is mounted on the top of the mounting bracket and is used to apply hot melt glue lines to the bonding areas of the forming paper. This adhesive line is controlled by an independent hot melt glue gun, directly completing the bonding of the forming paper overlap. Two parallel solenoid valves receive glue liquid through an external glue supply system and control the flow of glue liquid. The glue liquid enters from both sides of the nozzle through two conduits, ensuring uniform glue distribution. The nozzle position is fixed, eliminating the need for frequent adjustments, reducing wear and the risk of paper edge movement. The fixed nozzle and precisely designed glue outlet further reduce paper edge movement, improving glue application consistency and bonding quality. Controlled by the solenoid valve, the adhesive is extruded from the dispensing holes on both sides of the nozzle, resulting in two sets of adhesive lines. At the same time, the hot melt glue gun independently applies a third set of adhesive lines, achieving triple bonding. The structure is simplified, the cost is reduced, and it is suitable for large-scale industrial applications. It supports hot melt adhesives of various viscosities, is flexible in operation, does not require frequent shutdowns for cleaning, and has greater adaptability. The solenoid valve is a standard part with a long service life, and the fixed nozzle design reduces wear. The equipment operates stably and requires virtually no maintenance.

Detailed Implementation

[0027] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0028] like Figure 1-7 As shown, this application provides a glue applicator for bonding filter tip forming paper, comprising: a mounting bracket mechanism 100, a hot melt glue gun 200, and a forming paper glue applicator 300; wherein, the mounting bracket mechanism 100 is used to fix the glue applicator; the hot melt glue gun 200 is disposed at the top of the mounting bracket mechanism 100 and is used to apply hot melt glue for bonding the forming paper; the forming paper glue applicator 300 includes a base 310 disposed at the bottom end of the glue applicator, two solenoid valves 320 disposed side by side on the base 310, two conduits 330 respectively connected to the outlets of the two solenoid valves 320, and a glue nozzle 340 disposed at one end of the base 310, the two conduits 330 being respectively connected to both sides of the glue nozzle 340, one end of the glue nozzle 340 having two sets of glue outlet holes 345, the two sets of glue outlet holes 345 being used to apply glue lines for bonding the overlapping joints of the forming paper and for bonding the forming paper to the filter element, respectively, and the inlet of the solenoid valve 320 being connected to an external glue supply system.

[0029] Compared with the prior art, the glue applicator for bonding filter tip forming paper provided in this application applies two sets of glue lines (for bonding the overlapping parts of the forming paper and for bonding the forming paper to the filter element) through a single glue nozzle 340. A hot melt glue gun 200 is mounted on the top of the mounting bracket and is used to apply hot melt glue lines to the bonding parts of the forming paper. This glue line is controlled by an independent hot melt glue gun 200 to directly complete the bonding of the forming paper overlapping parts. Two parallel solenoid valves 320 receive glue liquid through an external glue supply system and control the flow of glue liquid. The glue liquid enters from both sides of the glue nozzle 340 through two conduits 330 to ensure uniform glue distribution. The glue nozzle 340 is fixed in position, eliminating the need for frequent adjustments and reducing the risk of wear and paper edge movement. The fixed glue nozzle 340 and the precisely designed glue outlet 345 reduce paper edge movement and improve glue application consistency and bonding quality. Controlled by the solenoid valve 320, two sets of adhesive streams are extruded from the dispensing holes 345 on both sides of the nozzle 340. At the same time, the hot melt glue gun 200 independently applies a third set of adhesive streams, achieving triple bonding function. The structure is simplified, the cost is reduced, and it is suitable for large-scale industrial applications. It supports hot melt glues of various viscosities, is flexible in operation, does not require frequent shutdowns for cleaning, and has greater adaptability. The solenoid valve 320 is a standard part with a long service life, and the fixed design of the nozzle 340 reduces wear. The equipment operates stably and requires virtually no maintenance.

[0030] It should be noted that in the two sets of glue outlet holes 345 at one end of the glue nozzle 340, each set of glue outlet holes 345 has at least one. Preferably, the number of glue outlet holes 345 used for bonding the overlapping joint of the forming paper is one, and the number of glue outlet holes 345 used for bonding the forming paper and the filter element is two.

[0031] In one possible implementation, such as Figure 2 and Figure 3The mounting bracket mechanism 100 includes a first X-axis adjustment component 110 for synchronously adjusting the positions of the hot melt glue gun 200 and the forming paper glue applicator 300. The first X-axis adjustment component 110 includes a first mounting base 111 for fixing the glue applicator, a first lead screw 112 rotatably mounted on the first mounting base 111, a first slider 113 screwed to the first lead screw 112, a first support member 114 rotatably connected to the end of the first lead screw 112 away from the first mounting base 111, and a first guide rod 115 whose two ends are respectively connected to the first mounting base 111 and the first support member 114 and slidably cooperate with the first slider 113. The first lead screw 112 is rotated by external force. Specifically, the first lead screw 112 is driven by external force (such as a motor or manual rotation), and its rotation causes the first slider 113, which is screwed to it, to move linearly along the X-axis. The first guide rod 115 passes through the slider and is fixedly connected to the mounting base and support, ensuring that the slider slides only along the X-axis when it moves, avoiding deviation or shaking. The first support 114 serves as a support structure at the end of the lead screw, and together with the mounting base and guide rod, it forms a stable mechanical frame, maintaining structural stability during the adjustment process. The movement of the slider directly drives the hot melt glue gun 200 and the forming paper glue applicator 300 to adjust their positions synchronously along the X-axis. By adjusting the rotation angle or stroke of the lead screw, the displacement of the glue applicator in the X-axis direction can be precisely controlled, thereby adapting to different production needs (such as adjusting the glue line position, matching the forming paper size, etc.).

[0032] In one possible implementation, the first X-axis adjustment assembly 110 further includes a first knob 116 disposed at the end of the first lead screw 112 and rotatably connected to the first support member 114. Specifically, the first knob 116 is mechanically fixedly connected to the end of the first lead screw 112. When the user manually rotates the first knob 116, the rotational motion of the knob is directly converted into the rotational motion of the lead screw. Since the lead screw and the slider are connected by a threaded transmission, the rotation of the lead screw will drive the slider to move linearly along the X-axis. This design is simple to operate, improves adjustment efficiency, requires no additional power source (such as a motor), and allows the user to complete the adjustment simply by manually rotating the knob. The operation is intuitive and requires no complex training.

[0033] In one possible implementation, such as Figure 4As shown, the mounting bracket mechanism 100 also includes a first Y-axis adjustment assembly 120 for adjusting the extension of the hot melt glue gun 200 in the direction perpendicular to the X-axis. The first Y-axis adjustment assembly 120 includes a second lead screw 121, a second slider 122 screwed to the second lead screw 121, two second support members 123 rotatably connected to both ends of the second lead screw 121, a second guide rod 124 connected to both ends of the two second support members 123, and a second mounting seat 125 for mounting the hot melt glue gun 200. The second lead screw 121 is rotated by an external force. Specifically, the second lead screw 121 is rotated by an external force (e.g., manual rotation or motor drive). Since the second slider 122 is screwed to the second lead screw 121, when the second lead screw 121 rotates, it drives the second slider 122 to move along the direction of the lead screw (i.e., the Y-axis direction). To ensure that the second slider 122 moves only along the Y-axis direction without deviation, the two second support members 123 and the second guide rod 124 work together. The second guide rod 124 passes through the second slider 122 and is fixed at both ends to the two second support members 123 respectively, so that the second slider 122 can slide smoothly along the guide rod. The hot melt glue gun 200 is installed in the second mounting seat 125 on the second slider 122. Therefore, as the second slider 122 moves along the Y-axis direction, the hot melt glue gun 200 also moves accordingly, thereby achieving precise adjustment of its extension amount. The Y-axis adjustment component allows users to flexibly adjust the position of the hot melt glue gun 200 according to different production needs, adapting to the bonding operations of filter tip forming paper of different specifications.

[0034] It should be noted that the second slider 122 is fixedly connected to the second mounting base 125, the second slider 122 is clearance-fitted with the first slider 113, and the two second support members 123 are fixedly connected to the first slider 113.

[0035] In one possible implementation, the first Y-axis adjustment assembly 120 further includes a second knob 126 connected to one end of the second lead screw 121. Specifically, the second knob 126 is fixedly connected to one end of the second lead screw 121 via a mechanical structure (such as a keyway, thread, or coupling). When the user manually rotates the second knob 126, the knob transmits rotational motion to the second lead screw 121, causing the lead screw to rotate synchronously. The user only needs to rotate the knob to complete the fine adjustment of the position of the hot melt glue gun 200, without the need for additional tools or complex control systems, making the operation intuitive and simple.

[0036] In one possible implementation, such as Figure 5As shown, the mounting bracket mechanism 100 also includes a second Y-axis adjustment component 130 for adjusting the forming paper gluing mechanism 300 in the direction perpendicular to the X-axis, and a second X-axis adjustment component 140 for adjusting the forming paper gluing mechanism 300 in the direction parallel to the X-axis. The second Y-axis adjustment component 130 is used to adjust the extension amount of the forming paper gluing mechanism 300, and the second X-axis adjustment component 140 is used to adjust the lateral position of the forming paper gluing mechanism 300 relative to the forming paper. The second Y-axis adjustment component 130 includes a third lead screw 131, a third slider 132 screwed to the third lead screw 131, two third support members 133 rotatably connected to both ends of the third lead screw 131, a third guide rod 134 connected to both ends of the two third support members 133, and a third mounting base 135 fixedly connected to the first slider 113. The third lead screw 131 is rotated by external force. Specifically, the third lead screw 131 is rotated by external force (such as manual or motor drive). Since the third slider 132 is screwed to the third lead screw 131, when the third lead screw 131 rotates, it will drive the third slider 132 to move along the Y-axis. The third guide rod 134 passes through the third slider 132 and is fixed at both ends to the two third support members 133 respectively, ensuring that the third slider 132 moves only along the Y-axis and avoiding any lateral deviation or swaying. The forming paper gluing mechanism 300 is installed in the third mounting seat 135 on the third slider 132. Therefore, as the third slider 132 moves along the Y-axis, the forming paper gluing mechanism 300 also moves, realizing precise adjustment of the extension amount of the forming paper gluing mechanism 300. Through the design of the lead screw and slider, fine position adjustment can be achieved, which is crucial to ensuring the quality of filter tip forming paper bonding. The second Y-axis and second X-axis adjustment components 140 allow users to independently adjust the position of the forming paper gluing mechanism 300 to adapt to different production needs.

[0037] In one possible implementation, a third knob 136 is provided at one end of the third lead screw 131. Specifically, the third knob 136 provides users with an intuitive and direct way of operation. The vertical (Y-axis) position of the forming paper gluing mechanism 300 can be adjusted simply by rotating it manually. Compared with electric or complex mechanical transmission methods, knob operation does not require power supply, control system or professional tools, and is suitable for various production environments. It is especially suitable for quick fine-tuning on site. Moreover, the manual knob drive method eliminates electrical components such as motors and encoders, reduces system complexity and potential failure points, and has a simple and reliable structure, thus reducing the failure rate.

[0038] In one possible implementation, such as Figure 6As shown, the second X-axis adjustment assembly 140 includes a fourth lead screw 141, a fourth slider 142 screwed to the fourth lead screw 141, two fourth support members 143 rotatably connected to both ends of the fourth lead screw 141, a fourth guide rod 144 connected to both ends of the two fourth support members 143, and a fourth mounting base 145 fixedly connected to the third slider 132. The fourth lead screw 141 is rotated by external force. Specifically, the fourth lead screw 141 rotates by external force (e.g., manual or motor-driven). Since the fourth slider 142 is screwed to the fourth lead screw 141, when the fourth lead screw 141 rotates, it drives the fourth slider 142 to move along the X-axis. The fourth guide rod 144 passes through the fourth slider 142 and is fixed at both ends to the two fourth support members 143, ensuring that the fourth slider 142 moves only along the X-axis, avoiding any vertical offset or wobbling. The forming paper gluing mechanism 300 is installed in the fourth mounting seat 145 on the fourth slider 142. Therefore, as the fourth slider 142 moves along the X-axis, the forming paper gluing mechanism 300 also moves, achieving precise adjustment of its lateral position relative to the forming paper. It is worth noting that the fourth mounting seat 145 is fixedly connected to the third slider 132, meaning that the Y-axis and X-axis adjustments can work independently or collaboratively to adapt to more complex production needs. The design of the lead screw and slider enables fine position adjustments, which is crucial for ensuring the quality of the filter tip forming paper bonding. The fourth guide rod 144 ensures the straightness of the fourth slider 142 during movement, reducing mechanical wear and improving the service life of the equipment.

[0039] In one possible implementation, a fourth knob 146 is provided at one end of the fourth lead screw 141. Specifically, the fourth knob 146 provides users with an intuitive and direct operating method; the lateral position adjustment of the forming paper gluing mechanism 300 can be completed simply by manually rotating it. Compared to electric or complex control systems, knob operation requires no power supply or programming control, making it suitable for various production environments, especially for rapid on-site fine-tuning. The manual knob drive eliminates electrical components such as motors and encoders, reducing system complexity and potential failure points, resulting in a simple and reliable structure and a lower failure rate.

[0040] In one embodiment, the first Y-axis adjustment component 120, the second Y-axis adjustment component 130, and the second X-axis adjustment component 140 may have the same structure, which improves the versatility of components and reduces manufacturing and maintenance costs.

[0041] In one possible implementation, the nozzle 340 has a symmetrical hollow structure, with the contour area of ​​the end near the base 310 being larger than that of the other end. Two guide tubes 330 are symmetrically connected to both sides of the nozzle 340. Specifically, the nozzle 340 has a symmetrical hollow structure, with the contour area of ​​the end near the base 310 being larger than that of the other end (i.e., the glue dispensing end). This design constitutes a tapered flow channel structure. The two guide tubes 330 are symmetrically connected to both sides of the nozzle 340 to deliver hot melt adhesive into the nozzle 340. The tapered structure from the large end to the small end can effectively accelerate the flow rate of the hot melt adhesive, while increasing the pressure concentration during extrusion. This is beneficial for forming a continuous and fine adhesive line, improving the uniformity, stability, and controllability of the adhesive dispensing, and also enhancing the anti-clogging ability and maintenance convenience of the nozzle 340. It is especially suitable for cigarette forming paper bonding processes with strict requirements for adhesive line quality.
