Description

Technical Field

[0001] This utility model relates to the field of glass bottle labeling technology, specifically an adsorption structure that can be adjusted during the labeling process. Background Technology

[0002] Labeling, or labeling, involves affixing labels to the surface of containers. Currently, self-adhesive labels are commonly used. Compared to traditional labels, self-adhesive labels offer advantages such as eliminating the need for glue, paste, and water, resulting in no pollution and saving time. They are widely applicable and convenient. Self-adhesive labels are a composite material made of paper, film, or other special materials as the face stock, coated with adhesive on the back, and with a silicone-coated release liner. After printing, die-cutting, and other processing, they become finished labels. Various types of self-adhesive labels can be used on materials where ordinary paper labels cannot be applied. In a sense, self-adhesive labels are versatile. The printing of self-adhesive labels differs significantly from traditional printing. Self-adhesive labels are typically printed and processed on label printing machines, completing multiple processes in one go, such as graphic printing, die-cutting, waste removal, sheet cutting, and rewinding.

[0003] When applying labels after they are taken out, the glass bottle surface is not flat and has a curved shape. The adsorbed label cannot be completely attached to the bottle, resulting in wrinkles on the label. This affects the integrity and appearance of the label, increases the workload for subsequent labeling, and may even cause the label to break during labeling, resulting in a high scrap rate and increased production costs. Utility Model Content

[0004] The purpose of this invention is to overcome the problems mentioned in the background art and to provide an adjustable adsorption structure during the labeling process. This adsorption structure can adjust the angle so that the label unfolds and fits the bottle body as closely as possible. The label can be completely adhered to the bottle body in one go, thereby improving the yield of qualified products.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] The adjustable adsorption structure during the labeling process includes a mounting plate with a main power mechanism connected to an air nozzle mounting plate, capable of rotating the air nozzle mounting plate. A fixed base is located below the air nozzle mounting plate, connected to it. Several adsorption nozzles are mounted on the bottom of the air nozzle mounting plate, their bottoms passing through and below the fixed base. A spring support plate is mounted on the bottom of the fixed base, containing a rotating shaft that passes through the fixed base with both ends outside. A spring pressure plate is fitted onto the outer wall of the portion of the rotating shaft outside the fixed base, allowing it to rotate around the axis of the rotating shaft. A return spring is fitted onto the outer wall of the portion of the rotating shaft outside the fixed base, with both ends contacting the top surface of the spring support plate and the bottom surface of the spring pressure plate, respectively. A limit cylinder is mounted on the air nozzle mounting plate, passing through it. A limit post is mounted on the bottom of the limit cylinder, its bottom positioned above and in contact with the top of the spring pressure plate. Currently, when labeling glass bottles, the labels are very thin and are usually applied using negative pressure adsorption. However, because the surface of the glass bottle is not flat and is curved, the adsorbed label cannot completely adhere to the bottle, resulting in wrinkles. This affects the integrity and aesthetics of the label, increases the workload for subsequent label removal, and can even cause label damage during removal, leading to a high scrap rate and increased production costs. To solve these problems, this solution designs an adjustable adsorption structure during label picking, including a mounting plate for mounting the solution on other equipment. The mounting plate has a main power mechanism connected to an air nozzle mounting plate, which can drive the air nozzle mounting plate to rotate. The main power mechanism preferably uses a servo motor, which rotates the air nozzle mounting plate to achieve angle adjustment. Height adjustment is achieved through overall movement, which will not be described here. A mounting base is installed below the nozzle mounting plate, and the mounting base is connected to the nozzle mounting plate. Several suction nozzles are installed at the bottom of the nozzle mounting plate. The bottom of the suction nozzles passes through the mounting base and is located below the mounting base. The suction nozzles have an existing structure, and their tops are connected to pipes. The pipes pass through the nozzle mounting plate and are connected to the nozzle mounting plate. The label is adsorbed using the principle of negative pressure adsorption. The pipes of the suction nozzles are elastic and can bend appropriately when subjected to lateral force. By changing the distance between the suction nozzles, the label can be tightened or unfolded, so that the label can fit a larger area with the bottle body, reducing the amount of subsequent labeling work and improving the pass rate. A spring support plate is installed at the bottom of the fixed base. A rotating shaft is set in the fixed base. The rotating shaft passes through the fixed base and its two ends are located outside the fixed base. A spring pressure plate is fitted on the outer wall of the part of the rotating shaft outside the fixed base. The spring pressure plate can rotate around the axis of the rotating shaft. Both the spring support plate and the spring pressure plate protrude from the fixed base. A return spring is fitted on the outer wall of the part of the rotating shaft outside the fixed base. The return spring is horizontally set in the figure. Its two ends extend out and contact the top surface of the spring support plate and the bottom surface of the spring pressure plate, respectively.During application, the label is pressed onto the corresponding position on the bottle body using the suction nozzles. Due to the curved structure of the bottle, a limiting cylinder is installed on the nozzle mounting plate to maximize the label's coverage area or achieve a taut finish. The limiting cylinder passes through the nozzle mounting plate, and a limiting post is installed at the bottom of the limiting cylinder. The bottom of the limiting post is located above the spring pressure plate and contacts the top of the spring pressure plate. Under normal conditions, the limiting post presses against the spring pressure plate, which is in a horizontal position. This keeps the bottoms of the suction nozzles at the same level, making it easier to complete the suction by ensuring all suction nozzles contact the label. When it is necessary to unfold or tighten the label after suction, the limiting cylinder moves the limiting post upward, and the spring pressure plate rotates upward under the action of the return spring. This causes some suction nozzles to move outward, making the label taut or unfolded. This results in a larger area adhered to the glass bottle, reduces wrinkles, makes subsequent label removal smoother, minimizes damage to the label, and increases the pass rate.

[0007] Furthermore, to ensure the structural positions and installation heights meet requirements and that operation is more stable, a support plate is fitted onto the outer wall of the portion of the rotating shaft located outside the fixed base. This support plate can rotate around the axis of the rotating shaft, and a spring pressure plate is fixed to the support plate. The end face of the spring pressure plate near the fixed base is recessed to form a hollow mounting groove. Both ends of the support plate are larger than the mounting groove. The support plate connects to both the rotating shaft and the spring pressure plate, and covers the mounting groove area. The support plate and the rotating shaft are at the same height, and the top of the support plate and the bottom of the spring pressure plate are fixed. The support plate and the spring pressure plate move synchronously.

[0008] Furthermore, two rotating shafts are arranged in parallel, each with a support plate fitted on it. A spring pressure plate and a corresponding support plate are fixed together. With this structural arrangement, as each rotating shaft rotates, the spring pressure plate and support plate rotate accordingly. Correspondingly, each spring pressure plate is also equipped with a limiting cylinder and a limiting post to allow the corresponding suction nozzle to unfold.

[0009] Furthermore, the support plate is provided with a through groove through which the suction nozzle passes. The through groove facilitates the passage of the suction nozzle. Since the pipe connecting the suction nozzle has a certain degree of elasticity, when the support plate rotates, it can drive the corresponding suction nozzle to rotate, changing the distance between the suction nozzles, thereby tightening or unfolding the label.

[0010] Furthermore, a connecting column is provided between the nozzle mounting plate and the fixed base, and the connecting column is fixed to both the nozzle mounting plate and the fixed base. By fixing the nozzle mounting plate and the fixed base through the connecting column, when the motor rotates and drives the nozzle mounting plate to rotate, the fixed base will also rotate accordingly, realizing the synchronous rotation of the entire adsorption structure.

[0011] In summary, the present invention has the following advantages compared with the prior art:

[0012] (1) When the suction nozzle of this solution is subjected to lateral force, it can bend appropriately and change the distance between the suction nozzles, so that the label can be tightened or unfolded, thereby allowing the label to adhere to the bottle body over a larger area, reducing the workload of subsequent labeling and improving the pass rate.

[0013] (2) Under normal conditions, the limiting post presses against the spring pressure plate, which is in a horizontal state. This keeps the bottom of the suction nozzles at the same level, making it easier to contact all the suction nozzles and labels during suction. When the label needs to be unfolded or tightened after suction, the limiting cylinder moves the limiting post upward, and the spring pressure plate rotates upward under the action of the return spring. This causes some of the suction nozzles to move outward, making the label tighten or unfold. This results in a larger area attached to the glass bottle and reduces wrinkles. The subsequent labeling is smoother, reducing damage to the label and increasing the pass rate.

[0014] (3) In this scheme, the rotating shafts rotate independently, and the spring pressure plate and the support plate rotate accordingly. Accordingly, each spring pressure plate should also be equipped with a limit cylinder and a limit post so that the corresponding suction nozzle can be unfolded.

[0015] (4) This solution uses a through groove to facilitate the passage of the adsorption nozzle. Since the pipe connecting the adsorption nozzle has a certain elasticity, when the support plate rotates, it can drive the corresponding adsorption nozzle to rotate, change the distance between the adsorption nozzles, and thus tighten or unfold the label.

[0023] like Figure 1 As shown, this embodiment provides an adjustable adsorption structure during the label-taking process, including a mounting plate 10. The mounting plate 10 is used to install this solution on other equipment. The mounting plate 10 has an L-shaped structure. To increase stability and firmness, reinforcing ribs 11 are provided on the mounting plate 10. An active power mechanism 9 is provided on the mounting plate 10. The active power mechanism 9 is connected to an air nozzle mounting plate 6, and the active power mechanism 9 can drive the air nozzle mounting plate 6 to rotate. The active power mechanism 9 is preferably a servo motor. The servo motor is connected to the air nozzle mounting plate 6 through a coupling 8. The rotation of the motor drives the air nozzle mounting plate 6 to rotate, thereby achieving angle adjustment.

[0024] A fixing seat 12 is provided below the nozzle mounting plate 6, and a connecting post 5 is provided between the nozzle mounting plate 6 and the fixing seat 12. The connecting post 5 is fixed to both the nozzle mounting plate 6 and the fixing seat 12. The nozzle mounting plate 6 and the fixing seat 12 are fixed by the connecting post 5. In this way, when the nozzle mounting plate 6 is rotated by the motor, the fixing seat 12 will also rotate accordingly, realizing the synchronous rotation of the entire adsorption structure.

[0025] A spring support plate 2 is installed at the bottom of the fixed base 12. Two parallel rotating shafts 3 are set in the fixed base 12. The rotating shafts 3 pass through the fixed base 12 and their two ends are located outside the fixed base 12. The outer wall of the part of the rotating shaft 3 located outside the fixed base 12 is fitted with a support plate 14, and the support plate 14 can rotate around the axis of the rotating shaft 3. A spring pressure plate 4 is fixed to the top of the support plate 14. When the rotating shafts 3 rotate, the spring pressure plate 4 and the support plate 14 rotate accordingly. Correspondingly, each spring pressure plate 4 is also equipped with a limiting cylinder 7 and a limiting post 13 so that the corresponding suction nozzle 1 can be unfolded. The end face of the spring pressure plate 4 near the fixed base 12 is recessed to form a hollow mounting groove. The two ends of the support plate 14 are larger than the mounting groove. The support plate 14 is connected to both the rotating shaft 3 and the spring pressure plate 4 and covers the area of ​​the mounting groove. The support plate 14 and the rotating shaft 3 are at the same height. The top of the support plate 14 and the bottom of the spring pressure plate 4 are fixed. The support plate 14 and the spring pressure plate 4 move synchronously to prevent interference. The outer wall of the portion of the rotating shaft 3 located outside the fixed base 12 is fitted with a return spring. The two ends of the return spring contact the top surface of the spring support plate 2 and the bottom surface of the spring pressure plate 4, respectively. Both the spring support plate 2 and the spring pressure plate 4 protrude beyond the fixed base 12. The return spring, which is horizontally positioned, extends outwards and contacts the top surface of the spring support plate 2 and the bottom surface of the spring pressure plate 4, respectively. It exerts a force on both the spring support plate 2 and the spring pressure plate 4; however, the spring support plate 2 remains stationary, while the spring pressure plate 4 can rotate under the applied force.

[0026] A limiting cylinder 7 is installed on the nozzle mounting plate 6, passing through the nozzle mounting plate 6. A limiting post 13 is installed at the bottom of the limiting cylinder 7, with the bottom of the limiting post 13 located above the spring pressure plate 4 and in contact with the top of the spring pressure plate 4. Under normal conditions, the limiting post 13 presses against the spring pressure plate 4, keeping the spring pressure plate 4 in a horizontal state. When the limiting cylinder 7 moves the limiting post 13 upward, the spring pressure plate 4 can rotate upward under the action of the return spring.

[0027] This design preferably includes four suction nozzles 1 installed at the bottom of the nozzle mounting plate 6. Two of the suction nozzles 1 pass through the base 12 and are located directly below it. A through groove is provided on the support plate 14, and the other two suction nozzles 1 each pass through one of the through grooves. Under normal conditions, the limiting post 13 presses against the spring pressure plate 4, keeping the spring pressure plate 4 horizontal. This ensures that the bottoms of all suction nozzles 1 are on the same horizontal plane, facilitating suction by ensuring all nozzles contact the label. When the label needs to be unfolded or tightened after suction, the limiting cylinder 7 moves the limiting post 13 upwards. The spring pressure plate 4, now freed from pressure, rotates upwards under the action of the return spring, causing the suction nozzles in the through grooves to move outwards, thus tightening or unfolding the label. This results in a larger area adhered to the glass bottle, reduces wrinkles, and makes subsequent label removal smoother, minimizing damage to the label and increasing the pass rate.
