Description

Technical Field

[0001] The present invention relates to a gluing system, specifically an improved strip box trademark paper gluing system for a YB65 packaging machine, belonging to the technical field of cigarette manufacturing. Background Art

[0002] The YB65 packaging machine includes a cigarette pack supply system, a strip box trademark paper supply system, a strip box trademark paper wrapping and forming system, and a drying and output system. The gluing work process is completed during the supply process of the strip box trademark paper. Before the transformation, the working principle of the gluing system was as follows: when the liquid level detector detected that the liquid level of the glue in the glue cylinder was low, the liquid level detector sent an electrical signal, the electromagnetic directional valve changed its direction, compressed air was introduced into the rodless cavity of the injection valve, the valve core of the injection valve moved downward to open, and the glue would be injected into the glue cylinder body. When the liquid level detector detected that the liquid level height reached the required height after injecting a certain amount of glue, it sent an electrical signal again, the electromagnetic directional valve changed its direction, the compressed air was closed, and the valve core of the injection valve reset under the action of the compression spring to close the injection. When the injection valve malfunctioned and did not reset and close under the action of the compression spring, the glue would keep being injected into the glue cylinder body. When the operator did not detect such a malfunction, the glue would continue to be injected into the glue cylinder body until the glue in the glue cylinder body overflowed, flowed into the equipment, and caused blockages in other places. After the blockage in other places was detected and the fault alarm stopped the machine, the operator would come to handle the shutdown fault. Only then would it be found that the glue in the glue cylinder body had overflowed. Then, the glue cylinder assembly would be disassembled, the excess glue would be poured out, the glue that overflowed into the equipment would be wiped, and it would be checked whether there was glue in the produced strip cigarettes and so on.

[0003] During the operation of the existing equipment, the following several malfunctions may occur in the gluing system:

[0004] 1. Glue injection failure in the glue cylinder. This situation is caused by blockage at the right angle of the glue tank for discharging glue. The liquid level detection works normally, the glue valve is normal, but the glue cannot come down continuously. The dry rubber in the glue tank blocks at the right angle bend, and it needs to be manually opened and processed in the glue tank area. Moreover, because it is a right-angle elbow, it is not easy to clean.

[0005] 2. Overflow of the glue in the glue cylinder. This situation generally occurs due to a malfunction of the glue valve for discharging glue. When the liquid level detector in the glue cylinder detects that the liquid level of the glue in the glue cylinder is low, it will send a signal, the solenoid valve is energized to work, compressed air is introduced into the glue valve, the glue valve opens and starts to inject glue. When it is detected that the liquid level rises to the set position, the solenoid valve is de-energized, the compressed air is cut off, and the glue valve resets and closes by the compression spring. When the glue valve malfunctions and cannot reset and close on time, the glue is continuously injected, and finally the glue overflows.

[0006] 3. There is too much dry rubber in the glue cylinder. When the equipment is running, it is easy to get stuck between the glue wheel and the glue scraping plate, resulting in no glue on the glue wheel, and thus no glue on the strip box label paper, ultimately causing product quality defects such as no glue points or poor adhesion on the strip box label paper.

[0007] 4. The glue outlet of the glue valve is prone to accumulating glue and forming crusts. During the glue injection process, the glue valve sprays the glue liquid into areas outside the glue cylinder, causing glue leakage. If it leaks into the equipment, it will also cause product quality defects such as cigarette packs sticking together, and flowing to the moving parts of the equipment will cause mechanical failures of the equipment.

[0008] 5. The glue scraping plate of the glue wheel is an integral long strip-shaped copper scraping plate. As long as it is adjusted, the glue amount of all glue wheels will change. When we want to adjust the glue amount of each glue wheel, we cannot obtain the desired glue amount for each glue wheel separately.

[0009] 6. The current glue cylinder is too large. Every time during weekly and monthly maintenance, all the glue in the glue cylinder needs to be poured out, resulting in a large amount of waste of the glue liquid. If the glue cylinder is not cleaned thoroughly, the glue is prone to forming crusts, leading to product quality accidents.

[0010] 7. The structural design of the glue wheel on the glue cylinder is unreasonable, making it quite difficult for the operator to clean during the cleaning process, and it cannot be cleaned thoroughly.

[0011] After retrieval, currently, the Chinese invention patent with the publication number CN220258519U discloses a strip box glue cylinder, including a rotating shaft, a glue roller, a first support member, a scraping member, a liquid level detection member, a power member, a glue cylinder body, and a glue cylinder cover. This invention does not add a flow detector between the glue storage tank and the glue valve, nor does it add a device for automatically opening and closing the glue valve. In this way, when the injection glue valve fails, there is no detection device to detect the failure of the glue valve and no warning device, and there is no device that can automatically close the injection glue pipeline when the glue valve fails to prevent the glue liquid from overflowing from the glue box; there is no overflow area set. When the injection glue valve fails, the glue liquid will overflow into the equipment, causing unnecessary downtime and the risk of product quality defects; the injection glue valve is still outside the glue box. When there is rubber glue scale on the glue head of the injection glue valve, the spraying direction of the injection glue valve is uncertain, and it is still possible to spray to parts outside the glue box, causing unnecessary downtime and the risk of product quality defects; the coating glue roller is not designed as a cylindrical integral type, but still the original concave type. It is not easy for the operator to clean the glue scale in the concave part when cleaning the coating glue wheel; it is not easy for the operator to observe the size of the glue amount on the glue wheel. In short, it is often very inconvenient.

[0012] Therefore, the key to solving the above technical problems is to develop an improved strip box label paper gluing system for the YB65 packaging machine that is stable, reliable, and highly practical. Summary of the Invention

[0052] As a further improvement of the above of the present invention, the glue cylinder compartment (21) is integrally in a cuboid structure with an open top and a hollow interior, and a push - pull handle (24) is connected to one outer wall of the glue cylinder compartment (21);

[0053] The glue cylinder cover (22) is provided with several openings that are penetrated and adapted to the glue - applying wheel (33) and the scraping film (43). At one end of the glue cylinder cover (22), there is also a glue cylinder cover hole that is penetrated and adapted to the liquid - level detector installation hole and the conveying pipe connection hole.

[0054] As a further improvement of the above - mentioned invention, a baffle (25) is further provided between the two glue cylinder cover holes inside the glue cylinder cover (22). The baffle (25) is used to prevent the glue from spraying onto the liquid - level detector (54).

[0055] At the glue cylinder cover hole on the inner side of the upper surface of the glue cylinder cover (22), a limiting support plate (26) is also provided. The limiting support plate (26) is used to limit the downward pressing position of the connecting plate (52).

[0056] Connecting columns (27) are detachably installed at the four corners of the top of the glue - applying working area of the glue cylinder chamber (21).

[0057] Among them, the width of the glue cylinder cover (22) is the same as the width of the glue - applying working area of the glue cylinder chamber (21). Connection ports adapted to the connecting columns (27) are provided at the four corners of the glue cylinder cover (22).

[0058] The working principle is as follows: During operation, when all equipment is running normally, when the liquid - level detector (54) detects that the liquid level of the glue in the glue - applying working area of the glue cylinder body (2) is low, the liquid - level detector (54) emits an electrical signal, the electromagnetic reversing valve changes its direction, and compressed air is introduced into the rodless cavity of the injection valve (15). The valve core of the injection valve (15) moves downward to open, and the glue will be injected into the glue cylinder body (2). When the liquid - level detector (54) detects that the liquid level height reaches the required height after injecting a certain amount of glue, the liquid - level detector (54) emits an electrical signal again, the electromagnetic reversing valve changes its direction, the compressed air is closed, and the valve core of the injection valve (15) resets under the action of the compression spring to close the injection. At this time, the flow - rate detection control valve (14) is in normal operation, without alarming and without automatically closing the flow - rate detection control valve (14).

[0059] When the glue injection valve (15) fails and the valve core of the glue injection valve (15) does not reset and close under the action of the compression spring, but the liquid level detector (54) has given a closing signal, the control device (PLC) on the packaging machine equipment (6) thinks that the glue injection valve (15) has been closed. At this time, the glue in the conveying pipe (11) is still flowing continuously. Then the flow detection control valve (14) will detect that there is still glue flowing in the conveying pipe (11). At this time, the flow detection control valve (14) will send out an alarm signal. If the operator discovers it in time, they will close the control valve (13) in time and then notify the maintenance personnel to repair the glue injection valve (15). When the flow detection control valve (14) sends a signal to the control device (PLC) for alarm for more than 30 seconds and the operator still does not find the alarm fault, then the control device (PLC) will send a signal in the program to close the self-switch controlled by the flow detection control valve (14), so that the glue will not continue to be injected into the glue cylinder body (2). When the alarm signal continues to alarm for 30 seconds and the operator still does not find the alarm fault, the control device (PLC) will send a shutdown signal in the program and send the signal to the screen of the external device to display "Glue injection valve (15) fault shutdown". Then the operator will deal with these faults in time to avoid the glue overflowing from the glue cylinder body (2). Among them, an overflow port is provided at the end of the newly designed partition plate (23) in the glue cylinder body (2). Its function is that when the glue injection valve (15) and the flow detection control valve (14) simultaneously have unexpected faults and cannot work properly, when too much glue is injected, it will flow out from the overflow port to the empty box part of the glue overflow buffer area; it will not flow to the working parts in the equipment either, because the edge of the fully enclosed glue cylinder cover (22) just aligns with the upper edge of the partition plate (23), so that the empty box part of the glue overflow buffer area is exposed outside, and when the operator conducts a patrol inspection, they can discover it in time and deal with it in time.

[0060] The beneficial effects of the present invention compared with the prior art are as follows:

[0061] 1. The material conveying mechanism designed by the present invention can reduce the workload of the operator in dredging the conveying pipe;

[0062] 2. Under the cooperative work of the liquid level detector, the control valve and the flow detection control valve of the present invention connected to the control device, it can effectively prevent the glue from overflowing from the glue cylinder;

[0063] 3. The glue coating assembly designed by the present invention can eliminate product quality defects such as no glue points and poor adhesion of the strip box trademark paper;

[0064] 4. The partition plate designed by the present invention is provided with an overflow port, which can make the glue flow out from the overflow port to the empty box part of the glue overflow buffer area when too much glue is injected in case of equipment failure, facilitating the operator to discover and deal with it in time during the patrol inspection, and can buffer for a period of time to avoid the glue flowing to other positions of the equipment;

[0065] 5. By adding a partition plate in the glue cylinder of the present invention, the glue application working area is reduced, and the amount of waste glue can be significantly reduced during each weekly and monthly maintenance, saving a large amount of glue.

[0066] 6. Due to the ingenious design of the present invention, most of the glue flows along with the rotation of the glue application wheel in the glue cylinder. With the stirring function of the glue application wheel itself, the amount of glue caking in the glue cylinder is effectively reduced, reducing the waste of glue.

[0067] 7. The glue application component designed by the present invention enables the operator to clean the glue application wheel more time - saving and labor - saving, and can also be cleaned thoroughly without dead corners.

[0068] 8. The scraping film designed by the present invention can be adjusted back and forth on the scraping plate, and the scraping work of the corresponding glue application wheel can be conveniently realized by adjusting the corresponding scraping film.

[0069] 9. The glue cylinder cover designed by the present invention adopts a fully enclosed design, which can better protect the glue from contacting the outside world, reduce the evaporation of the water content in the glue, and avoid the generation of rubber sheets.

[0088] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the technical solutions of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and embodiments.

[0089] As shown in the attached drawings of the specification Figure 1 to the attached drawings of the specification Figure 11 An improved strip box trademark paper gluing system for the YB65 packaging machine as shown, includes control equipment, and further includes: a material conveying mechanism 1, and a conveying pipe 11 is connected to the material conveying mechanism 1;

[0090] A glue cylinder body 2, the glue cylinder body 2 includes a glue cylinder chamber 21 and a glue cylinder cover 22 adapted to be installed with the glue cylinder chamber 21;

[0091] A glue coating assembly 3, the glue coating assembly 3 is arranged on one side inside the glue cylinder chamber 21;

[0092] The glue scraping assembly 4 is arranged inside the glue cylinder chamber 21 and is arranged close to the glue coating assembly 3;

[0093] The connecting mechanism 5, one end of the connecting mechanism 5 is connected to the packaging machine device 6, and the other end of the connecting mechanism 5 is movably connected above the glue cylinder cover 22;

[0094] Wherein, the output end of the conveying pipe 11 is detachably connected to the connecting mechanism 5, and both the material conveying mechanism 1 and the connecting mechanism 5 are connected to the control device.

[0095] Such as Figure 7 and Figure 10 As shown, the material conveying mechanism 1 includes:

[0096] The glue storage tank 12;

[0097] The control valve 13, the control valve 13 is connected below the glue storage tank 12;

[0098] The flow detection control valve 14, the upper end of the flow detection control valve 14 is connected to the control valve 13 through a straight joint, and the lower end of the flow detection control valve 14 is connected to the conveying pipe 11;

[0099] Wherein, the output end of the conveying pipe 11 is connected with an injection valve 15, and both the control valve 13 and the flow detection control valve 14 are connected to the control device.

[0100] In the present invention, the flow detection control valve 14 itself has a switching function and can also complete the switching function according to the signal prompt after receiving the signal. It includes two parts: a flow detector and an electric switching valve controlled by a flow monitor;

[0101] In the present invention, the control valve 13 is a manual ball valve; now the original right-angle joint of the equipment is changed to a straight joint, making it easier for the operator to dredge this part; the control valve 13 is installed below the glue storage tank 12, the upper end of the control valve 13 is connected to the glue storage tank 12, a right-angle joint is installed at the lower end of the control valve 13, and the other end of the right-angle joint is connected to the flow detection control valve 14;

[0102] The purpose of adding the flow detection control valve 14 between the delivery pipe 11 and the control valve 13 is as follows: when the liquid level detector 54 detects a low liquid level, the solenoid valve operates to open the compressed air, the glue injection valve 15 injects glue, the flow detection control valve 14 also operates normally when it detects flow. When the glue injection is detected by the liquid level detector 54 and the liquid level reaches the required level, the solenoid valve is powered off, the compressed air is cut off, and the glue injection valve 15 closes. At this time, the flow detection control valve 14 detects that the glue in the delivery pipe 11 is not flowing; when the glue injection valve 15 fails to return to the closed position, the glue keeps flowing, but the liquid level detector 54 has detected that the glue has reached the required level and sends a closing signal, yet the glue injection valve 15 is still injecting glue. At this time, the flow detection control valve 14 detects that the glue in the delivery pipe 11 is still flowing. At this time, the flow detection control valve 14 sends a signal, closes itself and shuts down the equipment, and sends the equipment fault information to the screen of the external device to display abnormal glue injection. The operator can then promptly discover the alarm and handle it to prevent the glue from overflowing the glue cylinder; after dealing with the blockage fault of the glue injection valve 15, reset the machine, the flow detection control valve 14 reopens, and the equipment operates normally.

[0103] Further, as Figure 2 shown Figure 6 in the figure, a partition plate 23 is also connected inside the glue cylinder chamber 21. The partition plate 23 divides the glue cylinder chamber 21 into a glue coating working area and an overflow buffer area. Among them, at least one overflow port is opened at the upper end of the partition plate 23.

[0104] In the present invention, the original glue cylinder body is too large. When the glue in the glue coating working area is less during the normal operation of the equipment, new glue will be added. In this way, the dry rubber skin will be washed to the front part of the glue coating wheel 33. When the glue coating wheel 33 rotates, the glue will be brought into the gap between the scraping film 43 and the glue coating wheel 33. Slightly, all the glue on the glue coating wheel 33 will be scraped off. In this way, when the coating film passes through the glue coating wheel 33, it will not be able to carry the glue, resulting in no glue on the glue coating part of the strip box trademark paper and producing defective products. Then, when the scab is severe and the rubber skin becomes drier and harder, it will jam the glue coating wheel 33, and the transmission gear 34 of the glue coating assembly 3 will be damaged. In addition, when the glue wheel rotates, the glue in the distance will not flow with the rotation of the glue wheel, so it is easy to produce dry glue scabs.

[0105] By adding the partition plate 23, the width of the existing glue cylinder body's glue coating working area is reduced by 9 cm in the width direction. In this way, the overall size of the glue cylinder body's glue coating working area becomes much smaller relatively, which can save a large amount of glue. Each time during weekly and monthly maintenance, the amount of glue to be discarded will be significantly reduced; at the same time, after the size is reduced, most of the glue is surrounded by the glue coating wheel 33. When the glue coating wheel 33 rotates, the glue also flows along with it, making the glue coating wheel 33 itself have a stirring effect, so it is not easy to produce glue scabs.

[0106] Further, as Figure 3 shown, the glue - applying assembly 3 includes:

[0107] The glue - applying wheel shaft coupling support base 31 is respectively arranged at the inner bottom on one side of the glue cylinder cabin 21;

[0108] The glue - applying wheel connecting shaft 32 is rotatably connected to the glue - applying wheel shaft coupling support base 31, and one end of the glue - applying wheel connecting shaft 32 extends outside the glue cylinder cabin 21;

[0109] The glue - applying wheels 33 are respectively connected to the glue - applying wheel connecting shaft 32;

[0110] The transmission gear 34 is connected to the end of the glue - applying wheel connecting shaft 32 above the outside of the glue cylinder cabin 21;

[0111] Among them, the glue - applying wheel 33 is integrally in a cylindrical structure.

[0112] In the present invention, the transmission gear 34 is connected to the transmission mechanism on the packaging machine equipment 6 for working;

[0113] The original material of the glue - applying wheel 33 was pure copper, and there was a concave structure on the side, so the overall glue - applying wheel device was relatively heavy, and it was laborious for the operator to carry and clean it; now the previous glue - applying wheel 33 is designed as a cylindrical structure with a flat side surface, and the pure copper material is re - selected to be made of aluminum alloy material, which is both light and wear - resistant. The glue - applying wheels 33 are sequentially installed on the glue - applying wheel connecting shaft 32. The specific axial position should be installed with reference to the axial position of the glue - applying sheet. After installation, it can be locked with fastening screws. It is more time - saving and labor - saving for the operator to clean, and it can also be cleaned thoroughly without dead corners.

[0114] The original glue - applying wheel connecting shaft is re - reformed. The original glue - applying wheel shaft coupling support base 31 is changed between the two left - hand glue - applying wheels 33. At the same time, the shaft at the left end of the glue - applying wheel 33 is removed to facilitate the installation of the connecting mechanism 5; the glue - applying wheel connecting shaft 32 at the non - transmission - gear 34 end is sleeved inside the glue - applying wheel 33 at this end, so that the glue - applying wheel connecting shaft 32 does not interfere with the liquid - level detector 54 and the injection valve 15.

[0115] Further, as Figure 5 shown, the glue - scraping assembly 4 includes:

[0116] The glue - scraping plate connecting seat 41 is symmetrically connected to the upper surface of the inner bottom plate of the glue cylinder cabin 21;

[0117] The glue - scraping plate 42 is connected above the two glue - scraping plate connecting seats 41;

[0118] The squeegee blade 43 is detachably mounted on the squeegee plate 42 respectively.

[0119] In the present utility model, the squeegee blade 43 is integrally in a "concave" shape structure.

[0120] Specifically, as Figure 5 shown, locking threaded locking hole groups corresponding to the respective coating wheels 33 are provided on the squeegee plate 42;

[0121] Squeegee blade connection through holes adapted to the locking threaded locking hole groups are provided on the squeegee blade 43;

[0122] Among them, the number of squeegee blades 43 corresponds to that of the coating wheels 33, and the squeegee blade connection through holes are oblong holes opened along the width direction of the squeegee blade 43.

[0123] In the present invention, the original squeegee plate 42 was fixed on the squeegee plate connection base 41. Now, a separate squeegee blade 43 is designed at the position of each coating wheel 33 corresponding on the squeegee plate 42. The squeegee blade 43 is fixed on the squeegee plate 42 by fastening screws. The mounting holes of the squeegee blade 43 are designed as oblong holes, which is beneficial to the front - rear adjustment of the squeegee blade 43. By adjusting the corresponding squeegee blade 43, the squeegee work for the corresponding coating wheel 33 can be conveniently realized.

[0124] Furthermore, as Figure 9 shown, the connecting mechanism 5 includes:

[0125] A connection base 51;

[0126] A connection plate 52, one end of the connection plate 52 is hingedly connected to the connection base 51, and a liquid level detector mounting hole and a delivery pipe connection hole are provided on the connection plate 52;

[0127] A handle 53, the handle 53 is connected to the other end of the connection plate 52 and is located outside the delivery pipe connection hole;

[0128] A liquid level detector 54, the liquid level detector 54 is mounted on the liquid level detector mounting hole of the connection plate 52;

[0129] Among them, the injection valve 15 of the delivery pipe 11 is detachably mounted on the delivery pipe connection hole of the connection plate 52, and the liquid level detector 54 is connected to the control device.

[0130] In the present invention, the handle 53 is integrally in an "L" - shaped structure. The opening after the connection of the handle 53 and the connection plate 52 faces outward, and one end rod of the handle 53 is located above the connection plate 52.

[0131] Specifically, as Figure 9 shown, an electrical detection switch 55 is further included, and the electrical detection switch 55 is arranged on the connection base 51;

[0132] The connecting seat 51 includes:

[0133] A fixing plate, which is connected to the packaging machine equipment 6;

[0134] A hinge seat, the bottom end of the hinge seat is connected to the upper surface of the fixing plate, and the upper part of the hinge seat is hingedly connected to the connecting plate 52;

[0135] Among them, the electrical detection switch 55 is arranged on the upper surface of the fixing plate near the end of the glue cylinder body 2, and the electrical detection switch 55 is connected to the control device.

[0136] In the present invention, the liquid level detector 54 and the glue injection valve 15 are respectively installed on the corresponding liquid level detector installation holes and the conveying pipe connection holes of the connecting plate 52. The fixing plate is installed on the machine base of the packaging machine equipment 6. An electrical detection switch 55 is also installed on one side of the fixing plate. When the connecting plate 52 swings downward in place, the electrical detection switch 55 is triggered, the liquid level detector 54 starts to work, and the glue injection valve 15 also starts to work. When the operator lifts the connecting plate 52 upward through the handle 53 and leaves the electrical detection switch 55, both the liquid level detector 54 and the glue injection valve 15 do not work. The design of the connecting mechanism 5 is to avoid interference with the liquid level detector 54 and the glue injection valve 15 when disassembling the glue cylinder assembly.

[0137] Further, the glue cylinder chamber 21 is integrally in a cuboid structure with an open top and a hollow interior. A push-pull handle 24 is connected to the outer wall on one side of the glue cylinder chamber 21;

[0138] A plurality of openings adapted to the glue application wheel 33 and the scraping film 43 are penetratedly opened on the glue cylinder cover 22. A glue cylinder cover hole adapted to the liquid level detector installation hole and the conveying pipe connection hole is also penetratedly opened at one end of the glue cylinder cover 22.

[0139] In the present invention, the glue cylinder cover 22 adopts a fully enclosed design. An opening position is left at the tangent position of the scraping film 43 and the glue application wheel 33 on the glue cylinder cover 22, so that the scraping film 43 can contact the glue application wheel 33, which can better protect the glue from contacting the outside world, reduce the evaporation of the moisture in the glue, and avoid the generation of rubber sheets; during installation, the lower edge on one side of the glue cylinder cover 22 is aligned with the upper edge of the partition plate 23, and the other three sides are aligned and installed with the other three sides of the glue application working area of the glue cylinder body.

[0140] Two glue cylinder cover holes corresponding to the liquid level detector installation hole and the conveying pipe connection hole of the connecting plate 52 are opened on the glue cylinder cover 22, which can enable the liquid level detector 54 and the glue injection valve 15 to enter the inside of the glue cylinder cover 22, and prevent the glue injection valve 15 from spraying the glue to parts outside the glue cylinder body 2 when spraying glue.

[0141] Specifically, a baffle 25 is also provided between two glue cylinder cover holes inside the glue cylinder cover 22, and the baffle 25 is used to prevent the glue from spraying onto the liquid level detector 54;

[0142] At the glue cylinder cover holes on the inner side of the upper surface of the glue cylinder cover 22, a limiting support plate 26 is also provided, and the limiting support plate 26 is used to limit the downward pressing position of the connecting plate 52;

[0143] At the four corners of the top of the glue application working area of the glue cylinder compartment 21, connecting columns 27 are detachably installed;

[0144] Among them, the width of the glue cylinder cover 22 is the same as the width of the glue application working area of the glue cylinder compartment 21, and connection ports adapted to the connecting columns 27 are provided at the four corners of the glue cylinder cover 22.

[0145] In the present invention, the width distance of the glue cylinder cover 22 is the distance from the non-push-pull handle 24 side of the glue cylinder compartment 21 to the partition plate 23.

[0146] In summary, a more specific embodiment of the present invention is as follows:

[0147] Before the improved strip box trademark paper gluing system for the YB65 packaging machine with the above design structure is used, it needs to be manufactured and installed for standby.

[0148] The specific usage steps are as follows: When in use, start the YB65 packaging machine to work. In the normal working state, the operator presses the handle 53. The electrical detection switch 55 detects the connecting plate 52, indicating that the connecting plate 52 is installed in place. At this time, the liquid level detector 54 works normally, the injection valve 15 works normally, and the flow rate detection control valve 14 also works normally; when the liquid level detector 54 detects that the liquid level of the glue in the glue application working area of the glue cylinder body 2 is low, the liquid level detector 54 emits an electrical signal, and the solenoid valve of the injection valve 15 works to change the direction. Positive pressure air enters the injection valve 15, pushes the valve core downward, and opens the injection port to start injecting glue. When a certain amount of glue is injected, when the liquid level detector 54 detects that the liquid level height reaches the set liquid level, the liquid level detector 54 emits an electrical signal again, the electromagnetic reversing valve of the injection valve 15 changes the direction, closes the compressed air, and the valve core of the injection valve 15 resets under the action of the compression spring to close the injection port. At this time, the flow rate detection control valve 14 is working normally, does not alarm, and does not automatically close the flow rate detection control valve 14;

[0149] When the glue injection valve 15 fails, such as a broken spring, insufficient elasticity, or excessive friction due to rust on the valve core, and the valve core of the glue injection valve 15 does not reset and close under the action of the compression spring, the glue injection port cannot be closed. Then the glue keeps injecting, and the situation of glue overflowing from the glue cylinder will occur. At this time, the liquid level detector 54 has given a closing signal, and the control device PLC on the packaging machine equipment 6 believes that the glue injection valve 15 has been closed. However, at this time, the glue in the conveying pipe 11 is still flowing continuously. Then the flow detection control valve 14 will detect that there is still glue flowing in the conveying pipe 11. At this time, the flow detection control valve 14 will send out an alarm signal, and a yellow warning message "Glue injector failure" will be displayed on the external device display screen. If the operator discovers it in time, they will close the control valve 13 in time and then notify the maintenance personnel to repair the glue injection valve 15. When the flow detection control valve 14 sends a signal to the control device PLC for alarm for more than 30 seconds and the operator still does not discover the alarm fault, then the control device PLC will send a signal in the program to close the self-switch controlled by the flow detection control valve 14, so that the glue will not continue to be injected into the glue cylinder body 2. When the alarm signal continues to alarm for 30 seconds and the operator still does not discover the alarm fault, the control device PLC will send a shutdown signal in the program and send the signal to the external device screen to display "Glue injection valve 15 failure shutdown". Then the operator will deal with these faults in time to avoid glue overflowing from the glue cylinder body 2.

[0150] Among them, an overflow port is provided at the end of the newly designed partition plate 23 in the glue cylinder body 2. Its function is that when the glue injection valve 15 and the flow detection control valve 14 both have unexpected failures and cannot work properly, when too much glue is injected, it will flow out from the overflow port to the empty box part of the glue overflow buffer area; it will not flow to the working parts in the equipment because the edge of the fully enclosed glue cylinder cover 22 just aligns with the upper edge of the partition plate 23, so that the empty box part of the glue overflow buffer area is exposed outside, and the operator can discover and deal with it in time during the inspection.

[0151] When it is necessary to pull out the glue cylinder assembly parts for cleaning or adjustment, lift the handle 53, and then the connecting plate 52 will also be lifted accordingly. The electrical detection switch 55 cannot detect the connecting plate 52. At this time, a warning slogan "Glue injection device opened" will be displayed on the external device screen. When the electrical detection switch 55 cannot detect the connecting plate 52, it will send a signal to the liquid level detector 54. At this time, the liquid level detector 54 will not work, and the glue injection valve 15 will not work either. However, at the same time, the flow detector 14 is working normally, and it can still detect that the glue in the pipe should not flow.

[0152] Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and is not a limitation on the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
