Description

Technical Field

[0001] This invention belongs to the field of adhesive supply technology, and specifically relates to a novel adhesive supply system. Background Technology

[0002] In cigarette rolling production lines, the glue supply system is the core equipment that ensures a stable and precise supply of adhesive for the cigarette rolling process, such as the closure glue and the tip glue. It directly affects the quality of cigarette bonding, production efficiency, and material loss. The core of the system lies in the four major objectives of "quantitative, stable, clean, and intelligent".

[0003] The existing glue supply system has the following problems: 1. During equipment maintenance, the glue tanks for joint glue and splice glue need to be cleaned and maintained frequently. At this time, the unused glue in the original glue tank needs to be poured out and the glue tank needs to be cleaned, which increases the consumption of raw materials and increases the production cost.

[0004] 2. When the equipment needs to be shut down for more than 2 days due to maintenance or completion of production plans, the unused glue inside the equipment needs to be poured out and cleaned to ensure the normal operation of the equipment afterwards, which also increases the production and manufacturing costs.

[0005] 3. During the cigarette production process, the adhesive surfaces of the sealing glue and tip glue are in contact with air for a long time. As a result, a thick layer of adhesive condenses on the adhesive surface and on the inner wall of the cigarette box, which reduces the quality of the adhesive coating during rolling and splicing, and affects the production quality of the product.

[0006] 4. During the production process, operations such as adding adhesive, maintaining equipment during production, and maintaining equipment after production may result in the adhesive storage tank not being completely sealed to isolate it from the atmosphere. This can lead to the mixing of airborne smoke, adhesive residue particles (clumps), dust, etc., with the adhesive, causing a decrease in adhesive quality and increasing quality defects.

[0007] Therefore, it is necessary to design a new type of glue supply system to overcome the above-mentioned defects. Summary of the Invention

[0008] To address the aforementioned problems in existing technologies, this solution provides a novel adhesive supply system.

[0009] The technical solution adopted in this invention is as follows: A novel adhesive supply system includes: glue supply cylinder; A soft bag for storing glue is placed inside the glue supply cylinder. The outlet of the soft bag extends from the bottom of the glue supply cylinder and is connected to a check valve. The base is detachably located below the glue supply cylinder. The base is provided with a glue filling port, a glue supply port, and a connecting seat. The connecting seat is connected to and communicates with the glue filling port and the glue supply port, and can be connected to a check valve.

[0010] Optional: It also includes a glue filling assembly, an air valve, and a stop mechanism; the glue filling assembly is connected to the glue filling port via a hose, and its glue supply pump is a pneumatic pump, with the air valve installed at the air supply end of the glue supply pump; the stop mechanism is located on the glue supply cylinder, and the glue storage bag controls the opening and closing of the air valve through the stop mechanism to stop the glue supply pump.

[0011] Optionally: The glue supply assembly includes a trolley and at least one glue storage tank mounted on the trolley, with each glue storage tank corresponding to a glue supply pump.

[0012] Optionally: The stopping mechanism includes a linkage rod, a linkage push handle, and a linkage seat; the linkage seat is fixed on the outer wall of the glue supply cylinder and rotatably connected to the linkage rod; one end of the linkage rod extends into the glue supply cylinder and is connected to the linkage push handle, and the other end is connected to the valve stem of the air valve; a limit pin is threaded onto the linkage seat, and the limit pin is used to limit the extreme rotation position of the linkage rod.

[0013] Optionally: The check valve includes a first sealing seat, a valve core, and a second sealing seat; the upper end of the first sealing seat is sealed to the outlet of the rubber storage bag, and the valve core is vertically and vertically disposed within the first sealing seat and sealed to the lower outlet of the first sealing seat; the second sealing seat is disposed below the first sealing seat and connected to the valve core; after the second sealing seat is sealed to the connecting seat, the second sealing seat is sealed to the first sealing seat, and at the same time, the first sealing seat can move downward to open its lower outlet, thereby connecting the check valve to the connecting seat.

[0014] Optionally: the second sealing seat is annular, and the bottom of the second sealing seat is provided with an adhesive outlet hole; the lower end of the central column of the valve core extends out of the first sealing seat and is fixedly connected to the second sealing seat.

[0015] Optionally: The upper end of the first sealing seat is connected to an end cap, and an adhesive inlet hole is provided on the end cap. A compression spring is provided between the end cap and the valve core.

[0016] Optionally: The first sealing seat is provided with an annular sleeve, and a V-shaped groove is provided on the outer peripheral wall of the annular sleeve. The base is provided with a locking device, and the locking tongue of the locking device is provided with an inclined surface. When the locking tongue moves horizontally, it can extend into the V-shaped groove and drive the annular sleeve and the first sealing seat to move downward.

[0017] Optional: The unlocking device includes a fixed base, a groove rail, and an operating handle; the fixed base is fixedly connected to the machine base, the groove rail is fixed on the fixed base, the lock tongue is U-shaped, the open end of the lock tongue is inserted into the V-shaped groove, and the handle end is connected to the operating handle.

[0018] The beneficial effects of this invention are as follows: 1. The glue supply system in this solution puts the glue into a soft bag. When replenishing or using glue, the glue is stored in the soft bag. Therefore, when production stops or the production line is maintained, only the soft bag needs to be removed, which not only saves time and effort, but also effectively reduces costs. 2. At the same time, the use of soft bags for storing glue can not only isolate air and dust, but also effectively coordinate the problem of excessive volume change caused by rapid addition of glue and slow use of glue. 3. The design of the stop mechanism linked with the glue supply pump effectively avoids the glue bag bursting due to human error during glue filling, thus improving safety. 4. The check valve effectively solves the sealing problem when the glue supply cylinder is removed from the machine base, effectively preventing glue waste and deterioration; at the same time, the locking device facilitates quick and easy loading and unloading of the glue supply cylinder.

Detailed Implementation

[0022] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0023] Example like Figures 1 to 5 As shown in the figure, this embodiment designs a novel glue supply system, including a glue supply component and a glue replenishment component.

[0024] The glue supply assembly includes components such as a locking device 4, a base 5, a glue supply cylinder 6, an air valve 7, a stop mechanism 8, a glue storage bag 9, and a leak valve 10.

[0025] The glue supply cylinder 6 can be a horizontally oriented prismatic barrel structure. An observation port 61 can be provided on the side wall of the glue supply cylinder 6 to facilitate observation of the amount of glue in the glue supply cylinder 6.

[0026] The base 5 is detachably located below the glue supply cylinder 6. The base 5 is provided with a glue filling port 51, a glue supply port 52 and a connecting seat 53. The connecting seat 53 is connected to and communicates with the glue filling port 51 and the glue supply port 52, and can be connected to the check valve 10.

[0027] The soft bag 9 for storing glue is placed inside the glue supply cylinder 6, and the outlet of the soft bag 9 extends from the bottom of the glue supply cylinder 6 and is connected to the check valve 10.

[0028] The stopping mechanism 8 includes a linkage rod 82, a linkage push handle 81, and a linkage seat; the linkage seat is fixed on the outer wall of the glue supply cylinder 6 and is rotatably connected to the linkage rod 82; one end of the linkage rod 82 extends into the glue supply cylinder 6 and is connected to the linkage push handle 81, and the other end is connected to the valve stem of the air valve 7; a limit pin 83 is threaded onto the linkage seat, and the limit pin 83 is used to limit the extreme rotation position of the linkage rod 82.

[0029] The check valve 10 includes a first sealing seat 101, a valve core 102, and a second sealing seat 104. The upper end of the first sealing seat 101 is sealed to the outlet of the adhesive storage bag 9. The valve core 102 is vertically and vertically disposed within the first sealing seat 101 and sealed to the lower outlet of the first sealing seat 101. The second sealing seat 104 is disposed below the first sealing seat 101 and connected to the valve core 102. After the second sealing seat 104 is sealed to the connecting seat 53, the second sealing seat 104 is sealed to the first sealing seat 101. At the same time, the first sealing seat 101 can move downward to open its lower outlet, thereby connecting the check valve 10 to the connecting seat 53. The second sealing seat 104 is annular, and an adhesive outlet hole is provided at the bottom of the second sealing seat 104. The lower end of the central column of the valve core 102 extends out of the first sealing seat 101 and is fixedly connected to the second sealing seat 104. The upper end of the first sealing seat 101 is connected to an end cap 106, and an adhesive inlet hole is provided on the end cap 106. A compression spring 105 is provided between the end cap 106 and the valve core 102.

[0030] The first sealing seat 101 is fitted with an annular sleeve 103. A V-shaped groove is provided on the outer peripheral wall of the annular sleeve 103. The base 5 is provided with a locking device 4. The locking tongue 44 of the locking device 4 is provided with an inclined surface. When the locking tongue 44 moves horizontally, it can extend into the V-shaped groove and drive the annular sleeve 103 and the first sealing seat 101 to move downward.

[0031] The unlocking device 4 includes a fixed base 42, a groove rail 43, and an operating handle 41; the fixed base 42 is fixedly connected to the base 5, the groove rail 43 is fixed on the fixed base 42, the locking tongue 44 is U-shaped, the open end of the locking tongue 44 is inserted into the V-shaped groove, and the handle end is connected to the operating handle 41.

[0032] The glue filling assembly includes components such as a trolley 1, a glue storage tank 2, and a glue supply pump 3.

[0033] The glue replenishment assembly includes a trolley 1 and at least one glue storage tank 2 mounted on the trolley 1, with each glue storage tank 2 corresponding to a glue supply pump 3. When using the glue replenishment assembly to replenish glue to the glue supply cylinder 6, the glue replenishment assembly is connected to the glue replenishment port 51 via a flexible hose.

[0034] The glue supply pump 3 is a pneumatic pump, and the air valve 7 is installed at the air supply end of the glue supply pump 3; the stop mechanism 8 is set on the glue supply cylinder 6, and the glue storage soft bag 9 controls the opening and closing of the air valve 7 through the stop mechanism 8 to stop the glue supply pump 3.

[0035] When using the novel adhesive supply system in this embodiment: When glue supply cylinder 6 is low on glue: A person manually pulls the trolley 1 to the glue supply cylinder 6, and connects the glue supply pump 3 to the glue replenishment port 51 via a hose, ensuring that the glue supply port 52 is closed. At this point, after the glue supply pump 3 starts, the glue in the glue storage tank 2 passes through the glue supply pump 3, the glue replenishment port 51, and the check valve 10, and is then fed into the glue storage bag 9. Once the glue storage bag 9 has been replenished, the glue replenishment port 51 is closed, and the hose is removed.

[0036] The working process of the stopping mechanism 8 is as follows: During the aforementioned glue replenishment process, as the amount of glue in the glue storage bag 9 increases, the bag continuously expands. When the height of the bag reaches the stop mechanism 8, the linkage push handle 81 pushes the linkage rod 82 upward, causing the other end of the linkage rod 82 to descend and control the operating end of the air valve 7, thereby closing the air valve 7. Once the air valve 7 is closed, air will no longer be supplied to the glue supply pump 3 (pneumatic pump), causing the glue supply pump 3 to stop working.

[0037] During the operation of the check valve 10: When the glue storage tank 2 needs to be removed from the base 5, pull the operating handle 41 outward. At this time, the locking tongue 44 moves horizontally outward, so that the inclined surface on the locking tongue 44 no longer provides downward pushing force to the annular sleeve 103. At this time, under the elastic force of the compression spring 105, the first sealing seat 101, the annular sleeve 103, the end cap 106 and other components move upward relative to the valve core 102, so that the valve core 102 seals at the lower end outlet of the first sealing seat 101, thereby preventing residual glue in the glue storage bag 9 from flowing downward. After that, the glue storage tank 2 can be moved to a designated location for cleaning.

[0038] When the glue storage tank 2 needs to be installed on the disassembly base 5, it must be confirmed in advance that the glue storage bag 9 is filled inside the glue storage tank 2, and that the outlet of the glue storage bag 9 extends out of the glue storage tank 2 and is connected to the check valve 10. When the glue storage tank 2 is placed on the base 5, the second sealing seat 104 of the check valve 10 is inserted into the connecting seat 53 and sealed to it. At this time, the first sealing seat 101 and the valve core 102 are still in a mutually sealed state. Pushing the operating handle 41 inward will push the locking tongue 44 inward. The inclined surface on the locking tongue 44 is inserted into the V-shaped groove of the annular sleeve 103 and cooperates with the inclined surface of the annular sleeve 103, thereby driving the first sealing seat 101, the annular sleeve 103, the end cap 106 and other components to move downward relative to the valve core 102, thereby opening the lower outlet of the first sealing seat 101, so that the glue can enter and exit the glue storage bag 9 through the check valve 10.

[0039] The above embodiments are merely illustrative examples and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
