Description

Technical Field

[0001] This utility model relates to the technical field of cigarette packaging equipment, and in particular to an adhesive coating device. Background Technology

[0002] The gluing device of the YB65A hard-pack cigarette packaging machine, such as Figure 1 As shown, the device mainly includes a glue roller, a glue storage box, and a scraper. The glue storage box has an internal cavity to hold the glue; there is a certain gap between the scraper and the circumferential surface of the glue roller. During glue application, the glue roller, partially immersed in the glue storage box, rotates within the glue storage box containing the glue. The glue adheres to the circumferential surface of the glue roller. Through the rotation of the glue roller, the glue is carried out of the glue storage box and then coated onto the packaging paper. The thickness of the glue layer on the surface of the glue roller is closely related to the size of the gap between the circumferential surface of the glue roller and the scraper. To ensure that the glue layer on the surface of the glue roller is thin and uniform, excess glue on the glue roller needs to be scraped off with the scraper before coating. Therefore, during the production process, it is necessary to pay close attention to the size of the gap between the scraper and the circumferential surface of the glue roller.

[0003] However, after prolonged use, the scraping edge of the scraper will wear down, and the gap between the scraper and the circumferential surface of the glue roller will increase, resulting in poor scraping effect and unstable glue application, thus affecting product quality. Current solutions to this problem mainly involve manually adjusting the scraper position based on experience. However, the scraper is directly fixed to the glue storage box with a nut, forcing the operator to repeatedly adjust and observe to determine if the glue layer thickness on the glue roller surface meets production requirements. Furthermore, the stability of a scraper fixed only by a nut during adjustment is poor. Therefore, this method of adjustment is not only complex and tedious but also time-consuming, significantly reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the gap between the circumferential surface of the scraper and the glue roller can only be adjusted manually based on experience through repeated adjustments and observations, resulting in poor stability, long time consumption, and low production efficiency. This invention provides a glue application device that can improve the stability of the adjustment process, thereby simplifying the gap adjustment process and improving production efficiency.

[0005] To solve the above-mentioned technical problems, an embodiment of this utility model discloses an adhesive application device, comprising:

[0006] The adhesive storage box has an internal cavity for holding the adhesive liquid.

[0012] A locking component, located on the base, is used to lock the moving block to restrict its movement relative to the base.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0038] In existing technologies, a scraper is commonly used to scrape the adhesive onto the rubber roller to adjust the thickness of the adhesive layer on the roller surface. For example... Figure 1 and Figure 2 As shown, a traditional glue coating device mainly includes a glue storage box 1, a roller 2, a glue roller 3, a glue storage box base 411, a scraper 5, locking screws 8, and a roller support 10. The glue storage box 1 contains glue liquid. The glue storage box base 411 and the roller support 10 are mounted on the glue storage box 1. The roller 2 is rotatably mounted on the roller support 10. The glue roller 3, sleeved on the roller 2, carries the glue liquid out of the glue storage box 1 and coats it onto the packaging paper during rotation. The scraper 5 has two oblong holes 9 (see reference). Figure 6 The locking screw 8 passes through the oblong hole 9 of the scraper 5 and is threaded into the glue storage box base 411. The scraper 5 has a scraping edge for scraping off excess glue from the surface of the glue roller 3. After a period of use, the edge of the scraper 5 that contacts the glue will wear, causing changes in the gap between the scraper 5 and the circumferential surface of the glue roller 3, resulting in changes in the glue layer thickness and unstable glue content on the surface of the glue roller 3.

[0039] The existing solution involves manually adjusting the position of the scraper blade 5 based on experience. During adjustment, the locking screw 8 is first loosened, and then the operator estimates the scraper blade 5 should be aligned along the first direction (e.g., based on the adhesive layer thickness). Figure 2 The distance the scraper blade 5 is advanced towards the rubber roller 3 in the x direction shown in the figure, and then the scraper blade 5 is moved to adjust the gap between the circumferential surface of the rubber roller 3 and the scraper blade 5. However, in this process, since the scraper blade 5 is only fixed to the top of the rubber storage box base 411 by the locking screw 8, the stability of the scraper blade 5 is poor during the gap adjustment process. Therefore, the operator can only make repeated adjustments based on experience, which greatly reduces the production efficiency.

[0040] To solve the above-mentioned technical problems, this utility model discloses an adhesive application device, such as... Figure 3 and Figure 4 As shown, it includes:

[0041] The adhesive storage box 1 has an internal cavity for holding the adhesive liquid;

[0042] Roller 2 is rotatably mounted on glue storage box 1;

[0043] A rubber roller 3 is sleeved on a roller shaft 2, and part of the circumferential surface of the rubber roller 3 extends into the cavity;

[0044] The base 4 is mounted on the glue storage box 1;

[0045] The scraper 5 is located above the base 4. The scraper 5 is detachably connected to the base 4. The scraper 5 has a scraping edge that extends along the axial direction of the roller shaft 2 and has a gap with the circumferential surface of the rubber roller 3.

[0046] The movable block 6 abuts against the side wall of the scraper 5. The movable block 6 is slidably disposed on the base 4 to push the scraper 5 to move relative to the glue roller 3 in a first direction, which is perpendicular to the axis of the roller shaft 2.

[0047] The locking component 7 is provided on the base 4. The locking component 7 is used to lock the moving block 6 to restrict the moving block 6 from moving relative to the base 4.

[0048] When adjustment is required, first loosen the locking assembly 7 to release its lock on the moving block 6. Then adjust the positions of the moving block 6 and the scraper 5 according to the gap size. When the gap is too large, push the moving block 6 and the scraper 5 towards the base 4, and then tighten the locking assembly 7. When the gap is too small, first slide the moving block 6 away from the base 4, then move the scraper 5 until its side wall abuts against the moving block 6, and then tighten the locking assembly 7.

[0049] Using the above technical solution, a slidable movable block 6 is provided on the base 4. By adjusting the position of the movable block 6 and making the scraper plate abut against the movable block, the size of the gap between the glue roller 3 and the scraper plate 5 can be indirectly adjusted, thereby controlling the glue layer thickness. In this application, since the movable block 6 and the base 4 have a slidable connection structure, the stability of the position adjustment of the movable block 6 can be improved, thereby avoiding repeated adjustments by the operator, simplifying the adjustment process, and improving adjustment efficiency.

[0050] Furthermore, the base 4 includes a base 41 and a fixing rod 42. The fixing rod 42 extends along a first direction, and one end of the fixing rod 42 is connected to the base 41. The movable block 6 has a through hole, which is fitted onto the fixing rod 42. A boss 61 is also provided on the side wall of the movable block 6 facing the base 4. The bottom surface of the boss 61 contacts the upper surface of the base 41 to restrict the movable block 6 from rotating around the axis of the fixing rod 42. Specifically, a groove is provided on the side wall of the boss 61, and one side of the scraper 5 is engaged in the groove.

[0051] By adopting the above technical solution, a fixed rod 42 extending in the first direction and a movable block 6 sleeved on the base 41 are provided, and the bottom surface of the boss 61 is always in contact with the upper surface of the base 41 during the adjustment process, so as to prevent the movable block 6 from rotating around the fixed rod 42 during the adjustment process. This allows the movable block 6 to slide stably on the fixed rod 42, thereby improving the stability of the device during the adjustment process.

[0052] Furthermore, the fixing rod 42 has an external thread on its circumferential surface. The locking assembly 7 includes a first nut 71 and a second nut 72 located on both sides of the through hole along the first direction. The fixing rod 42 passes through the first nut 71 and the second nut 72, and both the first nut 71 and the second nut 72 are threadedly connected to the fixing rod 42. Specifically, the external thread is a fine-pitch thread.

[0053] Furthermore, the first nut 71 is located on the side of the movable block 6 near the base 41, and the second nut 72 is located on the side of the movable block 6 away from the base 41.

[0054] By adopting the above technical solution, such as Figure 4 As shown, by setting a first nut 71 and a second nut 72 on both sides of the movable block 6, the position of the movable block 6 on the fixed rod 42 can be adjusted by rotating the first nut 71 and the second nut 72. When the gap between the scraper 5 and the circumferential surface of the rubber roller 3 is too large, firstly rotate the first nut 71 near the base 41 to make the first nut 71 move slightly toward the base 41, and then slide the movable block 6 toward the direction of the base 41 so that the movable block 6 abuts against the first nut 71. If the gap between the scraper 5 and the circumferential surface of the rubber roller 3 is still too large, repeat the above steps to continue adjusting the position of the first nut 71 and the movable block 6 until the gap between the scraper 5 and the circumferential surface of the rubber roller 3 is appropriate, then lock the second nut 72 so that the first nut 71 and the second nut 72 clamp and fix the movable block 6. When the gap is too small, first rotate the second nut 72 away from the base 41, causing a slight movement of the second nut 72 away from the base 41. Then slide the moving block 6 away from the base 41 until the moving block 6 abuts against the second nut 72. If the gap is still too small, repeat the above steps to continue adjusting the position of the second nut 72 and the moving block 5 until the gap is appropriate, then tighten the first nut 71. This application, by setting the external thread of the fixing rod 42 to a fine thread, allows for minute position adjustments by rotating the first nut 71 and the second nut 72, thereby improving the gap adjustment accuracy between the scraper plate 5 and the circumferential surface of the rubber roller 3 and reducing the difficulty of adjustment.

[0055] Furthermore, the second nut 72 is equipped with a butterfly knob, which facilitates operation and adjustment by the operator.

[0056] Furthermore, the adhesive application device also includes a locking screw 8, and the adhesive scraper 5 is provided with an oblong hole 9 extending in the first direction (see reference). Figure 6 The base 41 has a first threaded hole extending vertically at its top. The locking screw 8 passes through the waist-shaped hole 9 and is threaded into the first threaded hole. The locking screw 8 is used to fix the scraper 5 to the base 41.

[0057] Before adjusting the gap size, the locking screw 8 needs to be loosened to release its fixation on the position of the scraper 5. Then, the position of the moving block 6 is adjusted by rotating the first nut 71 and the second nut 72. The scraper 5 is then placed against the moving block 6, and the locking screw 8 is tightened to fix the position of the scraper 5.

[0058] For example, in one embodiment of this utility model, such as Figure 4 As shown, the base 41 includes a glue storage box base 411 and an adjustment mechanism base 412. The bottom of the glue storage box base 411 is fixedly connected to the glue storage box 1. A first threaded hole is opened on the glue storage box base 411. The adjustment mechanism base 412 is sleeved on the outside of the glue storage box base 411. A threaded hole is provided on the side wall of the adjustment mechanism base 412. The fixing screw 11 is threadedly connected to the threaded hole of the adjustment mechanism base 412. When the fixing screw 11 is tightened, it can press the glue storage box base 411 to prevent the adjustment mechanism base 412 from moving relative to the glue storage box base 411.

[0059] like Figure 1 As shown, existing glue-applying devices all include a glue storage box base 411 fixed inside the glue storage box 1. By adopting the above technical solution, and setting the base 41 as both the glue storage box base 411 and the adjustment mechanism base 412, it is easy to directly improve upon existing devices and simplify the device's processing flow.

[0060] Further reference Figure 5 There are two seats 4, two moving blocks 6, two locking components 7 and two locking screws 8. The two seats 4 are spaced apart along the axial direction of the roller shaft 2. Each moving block 6, locking component 7 and locking screw 8 corresponds to the two seats 4 respectively. Both moving blocks 6 abut against the scraper 5.

[0061] Furthermore, the glue application device also includes: two roller support seats 10 arranged axially along the roller shaft 2, the roller support seats 10 being disposed on the bottom surface of the internal cavity of the glue storage box 1, the two ends of the roller shaft 2 being rotatably disposed on the roller support seats 10 respectively, and the glue roller 3 being fixedly connected to the roller shaft 2.

[0062] Further reference Figure 6 The bottom surface of the scraper 5 near the scraping edge has an inclined surface, and the distance between the inclined surface and the upper surface of the scraper 5 gradually increases from the side near the scraping edge to the side away from the scraping edge. Specifically, the included angle between the inclined surface and the upper surface of the scraper 5 (e.g., ...) Figure 7 The α angle shown is 30°.

[0063] During operation, the roller 2 set on the glue storage box 1 rotates to drive the glue roller 3 to rotate. As the glue roller 3 rotates, the circumferential surface of the glue roller 3 is covered with glue. When the glue layer on the surface of the glue roller 3 is too thick, it is necessary to scrape the glue with the scraper 5 to remove the excess glue from the surface of the glue roller 3. At this time, the position of the scraper 5 needs to be adjusted.

[0064] If it is necessary to adjust the gap between the circumferential surface of the rubber roller 3 and the scraper 5, first loosen the two locking screws 8 on the scraper 5, and then adjust the position of the moving block 6 and the scraper 5 by rotating the first nut 71 and the second nut 72. After the position of the moving block 6 and the scraper 5 is adjusted, tighten the locking screws 8 to complete the adjustment.

[0065] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
