Description

Technical Field

[0001] This utility model belongs to the field of tobacco production line, especially the field of loading machine technology. Specifically, it relates to a scraping gap adjustment device for the scraping glue device of a loading machine. Background Technology

[0002] The glue supply device of the cigarette packing machine primarily functions to apply glue to the inner surface of the tipping paper. The glued tipping paper then wraps around the cigarette filter and part of the cigarette, forming the initial shape of the cigarette. The glue supply device includes components such as a glue cylinder, a glue supply roller, a glue scraper, and an applicator roller. The glue scraper and the glue supply roller work together to apply the glue from the glue cylinder to the surface of the glue supply roller. The glue supply roller then contacts the applicator roller, transferring the glue to its surface. The applicator roller then contacts the inner side of the tipping paper, completing the glue application. Controlling the gap between the glue supply roller and the glue scraper is crucial in this process.

[0003] If the gap is too large, the glue can easily pass through, resulting in excessive glue being applied to the surface of the glue supply roller. This creates a large glue pile at the joint between the glue application roller and the glue supply roller. Such a large glue pile will plasticize quickly upon contact with air, causing problems with the glue application and ultimately leading to quality issues such as cigarette leakage and cigarette tip detachment. It can also cause excessive glue to accumulate on subsequent components like the paper cutter and cigarette roller, affecting normal operation and posing significant risks to both the product and the equipment. Conversely, if the gap is too small, the glue pile will be too small, resulting in insufficient glue on the glue application roller or sudden glue interruption, leading to failed glue application on the tipping paper and making subsequent work impossible.

[0004] Regarding the amount of glue piled up, there are currently monitoring devices that collect images, identify them, and issue alarms to notify staff to make timely adjustments. The key to these adjustments lies in adjusting the gaps, and the gap adjustments also vary depending on the season.

[0005] However, conventional methods for adjusting the gap between the glue roller and the scraper require frequent disassembly and assembly of the glue roller. Furthermore, the internal space of the glue cylinder is limited, making it difficult to adjust quickly. Once adjusted, there is little incentive to adjust again. During the survey, the time for a single adjustment was 37 minutes. The adjustment also requires frequent rework and calibration, which significantly extends the time and reduces work efficiency.

[0006] In addition, the type of glue used varies with the season, and the glue supply roller will be replaced with a glue supply roller of the appropriate specification as needed, which makes it necessary to adjust the gap between the glue supply roller and the scraper. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a glue scraping gap adjustment device for a glue scraping machine that enables rapid gap adjustment and is easy to operate for calibration.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A glue scraping gap adjustment device for a glue scraping device of a receiving and loading machine includes a glue supply roller fixture and an adjustable glue scraper;

[0010] The glue supply roller fixture includes a shaft, bearings, a contour roller reference surface and a counterweight. The contour roller reference surface includes at least two local roller surfaces with different radii, which are spliced ​​together. The counterweight is located at the outer end of one of the local roller surfaces. A first step is provided at the adjacent ends of each local roller surface, and a second step is provided at the outer end of the local roller surface adjacent to the counterweight.

[0011] The adjustable scraper includes an L-shaped base and a support plate. The support plate is installed at the vertical structure of the L-shaped base with an adjustable vertical installation height. The top of the support plate cooperates with a first step or a second step, so that the support plate and each local roller surface form different adjustment references.

[0012] Furthermore, the shaft and bearing are both configured as standard-sized shafts and bearings that match the specifications of the glue supply device.

[0013] Furthermore, the reference surface of the contour roller is integrally formed with the shaft body.

[0014] Furthermore, along the axial direction, the central region of the reference surface of the contour roller is hollowed out, so that the reference surface of the contour roller forms two identical structures located at both ends of the shaft.

[0015] Furthermore, the counterweight is a plate-shaped or strip-shaped counterweight that spans and is fixed to one side of the reference surface of the contour roller.

[0016] Furthermore, the protrusion height of the first step and the second step is greater than the height of any local roller surface.

[0017] Furthermore, a gap adjustment mechanism and a locking mechanism are installed on the vertical structure and support plate of the L-shaped base. The gap adjustment mechanism includes an adjustment shaft with a nut structure, a locking bolt, and a through hole installed on the vertical structure of the L-shaped base. The support plate is provided with a square hole and a vertical hole. The nut structure of the adjustment shaft with a nut structure has a different radius on each side. The nut structure is located in the square hole and supports the inner wall of the top of the square hole to realize the adjustment of the height of the support plate.

[0018] The vertical hole and locking bolt are used to lock the support plate.

[0019] Furthermore, the gap adjustment mechanism and the locking mechanism are at least located at both ends of the adjustable scraper.

[0020] The beneficial effects of the utility model are:

[0021] 1. The designed fixture is fabricated as only a portion of the roller surface, with different radii, separated by a stepped structure, and stabilized by counterweights. The scraper is designed as an L-shaped base with a support plate, which can be flexibly adjusted vertically. This design allows for easy adjustment of the gap by simply adjusting the support height of the support plate. When changing the glue and supply roller due to seasonal changes, a suitable portion of the roller surface can be used with the support plate, demonstrating strong adaptability. After the fixture is adapted, the supply roller fixture can be removed and replaced with a solid supply roller.

[0022] 2. The shaft and bearing are designed to standard dimensions, consistent with the glue supply roller, and the shaft and the reference surface of the contour roller are designed as an integral structure, which can minimize the accumulation of assembly errors.

[0023] 3. To prevent the tooling from being too large or taking up too much space inside the glue cylinder, the middle area is hollowed out, leaving only the two ends. This makes operation and observation easier and reduces the structure and costs.

[0024] 4. The gap adjustment mechanism uses an adjustment shaft with a nut structure. The nut structure is designed with different radii on each side. Each time the angle is rotated, the height of the support plate will be finely adjusted, thus achieving gap adjustment. Attached Figure Description

Detailed Implementation

[0030] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.

[0031] like Figures 1 to 3 As shown, this application provides a glue scraping gap adjustment device for a glue scraping device of a receiving and loading machine, including a glue supply roller fixture and an adjustable glue scraper.

[0032] The glue supply roller fixture includes a shaft 1, a bearing 2, a contour roller reference surface 3, and a counterweight 4. The shaft 1 and bearing 2 are both set to standard sizes that match the specifications of the glue supply device. Their dimensions are the same as the shaft and bearing dimensions of the glue supply roller to avoid installation errors. The contour roller reference surface is an integrally formed structure with the shaft, which can also avoid the accumulation of errors caused by assembly.

[0033] The reference surface 3 of the contour roller includes three local roller surfaces with different radii: a first local roller surface 31, a second local roller surface 32, and a third local roller surface 33. The radii of the three roller surfaces increase sequentially. The three local roller surfaces are spliced ​​together. A counterweight 4 is set at the outer end of the third local roller surface 33. A first step 34 is set at the adjacent ends of the three local roller surfaces. A second step 35 is set at the outer end of the local roller surface adjacent to the counterweight. The protrusion height of the first step and the second step is greater than the height of any local roller surface.

[0034] The main function of the three local roller surfaces is to simulate the radius of different glue supply rollers that are replaced in different seasons. The function of each step is to constrain the position of the glue scraper so that it can only contact the current local roller surface, without the need for manual rotation and to maintain the state of the glue supply roller fixture.

[0035] Along the axial direction, the middle area of ​​the reference surface 3 of the contour roller is hollowed out, so that the reference surface of the contour roller forms two identical structures located at both ends of the shaft. The counterweight is a plate-shaped or strip-shaped counterweight that spans and is fixed on one side of the reference surface of the contour roller.

[0036] In this application, the adjustable scraper includes an L-shaped base 5 and a support plate 6. The support plate 6 is installed at the vertical structure 51 of the L-shaped base 5 with an adjustable vertical installation height. The top of the support plate 6 cooperates with the first step 34 or the second step 35, so that the support plate and each local roller surface form different adjustment references.

[0037] The gap adjustment mechanism and the locking mechanism are located at least at both ends of the adjustable scraper, and the gap at both ends is adjusted to avoid a height difference between the left and right ends.

[0038] A gap adjustment mechanism and a locking mechanism are installed on the vertical structure 51 of the L-shaped base 5 and the support plate 6. The gap adjustment mechanism includes an adjustment shaft 52 with a nut structure, a locking bolt 53, and a through hole installed on the vertical structure of the L-shaped base. The support plate 6 is provided with a square hole 61 and a vertical hole 62. The nut structure of the adjustment shaft 52 with the nut structure has a different radius on each side. The nut structure 54 is located in the square hole 61 and cooperates with the top inner wall of the square hole 61 to realize the adjustment of the height of the support plate 6. The vertical hole 62 and the locking bolt 53 are used to lock the support plate 6.

[0039] Working principle:

[0040] First, remove the glue supply roller and install the glue supply roller fixture in place. Pay attention to whether the bearings at both ends are installed correctly to avoid assembly errors.

[0041] Secondly, during the installation of the tooling, depending on the season, a local roller surface that is suitable for the current season is selected as a reference. For example, if the current season is suitable for the second local roller surface 32, the reference surface 3 of the contour roller is rotated by a certain angle so that the support plate 6 can cooperate with it, so that the support plate 6 and the corresponding first step are mutually constrained and limited within the adjustment range. Since the adjustment scale of the adjustment gap is small, it is essential to achieve the position matching of the second local roller surface 32 and the support plate 6 during the installation process.

[0042] Third, loosen the locking bolt 53 and tighten the adjusting shaft 52 with the nut structure to switch the nut structure 54 to different radius sizes. At the same time, use measuring tools such as a steel ruler to check the gap size. After reaching the appropriate size, lock the locking bolt 53.

[0043] In addition, if there are three local roller surfaces as in this embodiment, it means that the size of the glue supply roller varies greatly, and the size range that an adjustment shaft 52 with a nut structure can provide is limited. Designing this part as a replaceable part, for example, designing it as three sets of sizes, corresponding to the adjustment of the three local roller surfaces respectively, can increase the accuracy and flexibility of the gap adjustment.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
