Description

Technical Field

[0001] This utility model relates to the technical field of labeling machine equipment, and more specifically, to a water immersion tank structure. Background Technology

[0002] In the label peeling process, although existing technologies reduce the label breakage rate through pre-wetting treatments such as wiping or soaking, they cannot fundamentally solve the tearing problem, resulting in a low yield rate for a long time. This makes it difficult to meet the high-quality production needs of high-value, high-precision label products. This defect directly limits the application of the labeling process in the high-end manufacturing field and has become a key bottleneck restricting the improvement of production quality.

[0003] The existing label peeling and pre-wetting processes have significant efficiency shortcomings. Traditional manual or simple mechanical label peeling is slow and difficult to keep up with the pace of automated production lines. The water soaking and pre-wetting process takes a long time due to the soaking and waiting method, which leads to a significant decrease in the overall production efficiency of the labeling machine. This inefficiency not only slows down the overall progress of the packaging process, but also further exacerbates the problem of low yield rate, which seriously affects economic benefits.

[0004] In addition, existing label immersion tanks have multiple technical defects: the temperature control system is rudimentary, resulting in large water temperature fluctuations and excessively large local temperature differences, leading to unstable label adhesive performance; the tank structure is poorly designed, with insufficient water circulation and large local temperature differences, affecting the uniform immersion of labels; after long-term operation, ink and fiber shedding causes the water to become turbid, significantly reducing transparency, interfering with visual inspection and causing label stains; at the same time, the water circulation and filtration system is imperfect, failing to remove impurities in a timely manner, further deteriorating the label immersion effect and labeling quality. Utility Model Content

[0005] The present invention aims to provide a water immersion tank structure to solve the problems of low yield, complex process, time and labor consumption, low production efficiency and complex production process in the label water immersion process of the prior art.

[0006] The embodiments of this utility model are implemented as follows:

[0007] This utility model embodiment provides a water immersion tank structure, which includes an immersion pool;

[0008] The aforementioned soaking pool has an annular bottom, with an annular cam vertically welded to the inner ring of the annular bottom and an outer pool wall vertically welded to the outer ring of the annular bottom.

[0009] The aforementioned annular cam has a rotating seat inside, and a servo motor is connected to the center of the bottom of the rotating seat;

[0010] The outer wall of the aforementioned rotating seat is evenly hinged with a plurality of swing arm assemblies for accommodating labels, and the plurality of the aforementioned swing arm assemblies correspond to the aforementioned annular pool bottom.

[0011] One of the aforementioned annular cams has a cam low point, and a label pressing assembly is provided on the upper part of the aforementioned annular pool bottom corresponding to the aforementioned cam low point. A swing arm lifting assembly is provided in the gap between the aforementioned rotating seat and the aforementioned cam low point of the aforementioned annular cam.

[0012] In use, the servo motor drives the rotating seat to rotate counterclockwise. The rotating seat, along with the rocker arm assembly, rotates around the center of the soaking tank along the annular cam. When the rocker arm assembly rotates with the annular cam to the high position of the annular cam, it floats on the water surface at the bottom of the annular tank. When the rocker arm assembly rotates with the annular cam to the low position of the cam, the label pressing assembly accurately presses down on the rocker arm assembly, allowing it to be fully immersed in the water and the label to be fully submerged. In case of a sudden shutdown, the rocker arm lifting assembly can support the rocker arm assembly to prevent the label from being damaged by prolonged pressure.

[0013] The immersion tank structure disclosed in this embodiment, by incorporating the aforementioned immersion pool, swing arm assembly, label pressing assembly, and swing arm lifting assembly, achieves efficient and automatic label immersion, effectively solving the problems of low yield and long time consumption in traditional label immersion processes. Consequently, this immersion tank structure offers the beneficial effects of high yield in the label immersion process, simple procedures, short time consumption, improved production efficiency, and optimized production flow.

[0014] Optionally: A plurality of hinge seats are evenly installed on the outer wall of the aforementioned rotating seat, and a plurality of the aforementioned rocker arm assemblies each have a rocker arm, the end of the rocker arm near the aforementioned rotating seat being hinged to the aforementioned hinge seat.

[0015] This configuration allows the swing arm assembly to hinge and swing on the rotating seat via the hinge seat. When the swing arm assembly rotates along the annular cam from the higher position to the lower position, the arrangement of several hinge seats causes the swing arm assembly to convert the rotational motion into an up-and-down reciprocating motion, thereby gradually immersing the swing arm assembly in water until it is completely submerged, thus achieving full immersion of the label.

[0016] Optionally, a label connecting rod is detachably connected to the end of the swing arm away from the rotating seat, and a label base plate is welded to the end of the label connecting rod away from the swing arm, and several through holes are provided on the label base plate.

[0017] With this configuration, the label connecting rod and the swing rod are interconnected, which facilitates the installation or replacement of the label base plate. It also allows for the installation of different models of label base plates on the swing rod. Several through holes are provided on the label base plate to optimize the water flow path, enhance the uniformity of water immersion, and ensure that the label is fully immersed and drained. When the swing rod assembly moves from the lower part of the cam to the higher part of the annular cam, excess water after label immersion will flow away through the through holes, ensuring that the label humidity is appropriate. This facilitates the separation of the label from the backing paper, preventing the backing paper from sticking to the label due to excessive moisture content, thereby improving the label dryness and labeling effect.

[0018] Optionally, the top surface of the label base plate is provided with a first label fixing block, a second label fixing block, a third label fixing block and a fourth label fixing block at four positions. The first label fixing block, the second label fixing block, the third label fixing block and the fourth label fixing block surround each other to form a receiving groove, and the label is located in the receiving groove.

[0019] With this configuration, the receiving groove formed by the first label fixing block, the second label fixing block, the third label fixing block, and the fourth label fixing block can accommodate the label to be immersed in water. Furthermore, the side of the first label fixing block, the second label fixing block, the third label fixing block, and the fourth label fixing block closest to the receiving groove can initially clamp the label to be immersed in water, thereby fixing the label during the initial immersion stage before it comes into contact with the label pressing assembly, effectively preventing the label from floating on the water surface.

[0020] Optionally, the first label fixing block, the second label fixing block, the third label fixing block, and the fourth label fixing block are slidably connected to the label base plate;

[0021] The first label fixing block, the second label fixing block, the third label fixing block, and the fourth label fixing block are all provided with a plurality of oblong holes. The first label fixing block, the second label fixing block, the third label fixing block, and the fourth label fixing block are all connected to the label base plate by screws passing through the oblong holes.

[0022] This configuration, by adjusting the positions of the first, second, third, and fourth label fixing blocks on the label base plate and fixing them with screws, not only ensures the stability of the label immersion process but also facilitates the efficient removal of the labels later. Furthermore, the engagement of the screws with the oblong holes allows the first, second, third, and fourth label fixing blocks to adjust their displacement and lock, facilitating changes in the size of the receiving groove. This allows the receiving groove to adapt to various label types, meeting labeling requirements.

[0023] Optionally: The label pressing assembly has a horizontal support, with a first column and a second column vertically connected to the bottom surfaces of both ends of the horizontal support, and an arc-shaped pressing plate connected to the end of the first column and the second column away from the horizontal support, the arc-shaped pressing plate being submerged below the liquid level of the soaking tank.

[0024] In this configuration, to prevent the labels from floating during immersion, the label pressing component is positioned on one side of the lower part of the annular cam. When the rocker arm assembly rotates to the lower part of the cam, the arc-shaped pressing plate on the label pressing component accurately presses down on the receiving groove, which is then fully immersed in water. This effectively prevents the labels from floating, allowing for rapid, uniform, and stable automatic immersion of the labels. This significantly improves the yield rate of the label immersion process, while also significantly shortening the process time and increasing overall production efficiency.

[0025] Optionally, the label pressing assembly also has a motor for driving the first column and the second column to rise and fall, and a C-shaped frame is connected to the outer side of the horizontal support. The end of the C-shaped frame away from the horizontal support is connected to the bottom of the soaking tank.

[0026] With this configuration, the motor can drive the first column and the second column to rise, which makes it easier for the swing arm lifting assembly to push the swing arm assembly, which is submerged in water, out of the water surface. The C-shaped frame can effectively suspend the horizontal support above the annular pool bottom corresponding to the lower part of the cam.

[0027] Optionally: the above-mentioned rocker arm lifting assembly has a drive cylinder, a crescent-shaped top plate is provided in the gap between the rotary seat and the lower part of the annular cam, the output shaft of the drive cylinder is connected to a push plate, and a first top column and a second top column that are parallel to each other and spaced apart are vertically connected to the side of the push plate away from the drive cylinder, and the ends of the first top column and the second top column away from the push plate are welded to the bottom surface of the crescent-shaped top plate.

[0028] With this configuration, the aforementioned drive cylinder drives the aforementioned crescent-shaped top plate to rise and fall, thereby driving the aforementioned swing arm assembly to rise and fall as a whole. Under special working conditions, such as when the equipment suddenly stops, the motor drives the aforementioned arc-shaped pressure plates at the bottom of the aforementioned first column and the aforementioned second column away from the water surface. The aforementioned swing arm lifting assembly can quickly move to lift the aforementioned swing arm assembly above the water surface, preventing the label from being damaged or scrapped due to prolonged immersion, effectively ensuring the integrity and usability of the label.

[0029] Optionally, a number of support columns are installed on the bottom surface of the aforementioned annular pool bottom, one end of the aforementioned support columns is bolted to the bottom surface of the aforementioned annular pool bottom, and the other end of the aforementioned support columns is bolted to a support platform.

[0030] With this configuration, the aforementioned support columns effectively raise the soaking tank, thereby facilitating the installation of the servo motor at the bottom of the soaking tank.

[0031] Optionally: The soaking tank is equipped with a water circulation temperature control system. The water circulation temperature control system has an outlet and an inlet. The outlet and the inlet are respectively fixed on the bottom of the annular tank and connected to the soaking tank. The outlet is connected to an outlet pipe, and the inlet is connected to an inlet pipe. A water pump and a heater are connected between the outlet and the inlet pipe. A filter is installed on the inlet pipe. Several temperature sensors are installed on the bottom of the soaking tank. The several temperature sensors are electrically connected to the water pump through a control board.

[0032] With this setup, several temperature sensors detect a drop in water temperature in the soaking tank and transmit signals to the control board. The control board then activates the water pump, which draws water from the outlet. The water flows through the outlet pipe to the heater, which heats the water according to the temperature required by the label. The heated water then flows through the inlet pipe and filter into the soaking tank, thus circulating the water. The heater can be pre-set to provide the water temperature according to the labeling process requirements and is precisely adjusted to ensure that the output water temperature is kept constant within ±1℃. This improves the stability of the label adhesive and the adhesion of the label. The filter promptly removes impurities from the water in the soaking tank, maintaining the cleanliness and transparency of the water, preventing labels from becoming stained, further improving labeling quality, and ensuring stable operation of the equipment in complex industrial environments.

[0033] Optionally: The bottom of the rotary seat is provided with a motor frame, the motor frame is fixed on the support platform, the body of the servo motor is bolted to the bottom surface of the motor frame, the output shaft of the servo motor passes through the motor frame and is driven to the bottom axis of the rotary seat, and the drive cylinder is bolted to the outer side wall of the motor frame.

[0034] With this configuration, the aforementioned motor frame provides a platform for the installation of the aforementioned servo motor and drive cylinder.

[0035] In summary, the water immersion tank structure disclosed in this utility model has the beneficial effects of high yield rate in the label water immersion process, simple process, short time consumption, improved production efficiency and optimized production process.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0045] Example

[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment proposes an immersion tank structure, including an immersion pool 1;

[0047] The soaking pool 1 has an annular pool bottom 2, an annular cam 3 is vertically welded to the inner ring of the annular pool bottom 2, and an outer pool wall 4 is vertically welded to the outer ring of the annular pool bottom 2.

[0048] The annular cam 3 has a rotating seat 5 inside, and a servo motor 6 is connected to the center of the bottom of the rotating seat 5;

[0049] Several swing arm assemblies 7 for accommodating labels are evenly hinged to the outer wall of the rotating seat 5, and the swing arm assemblies 7 correspond to the annular pool bottom 2.

[0050] The annular cam 3 has a cam low point 8, and a label pressing assembly 9 is provided on the upper part of the annular pool bottom 2 corresponding to the cam low point 8. A swing arm lifting assembly 10 is provided in the gap between the rotating seat 5 and the cam low point 8 of the annular cam 3.

[0051] In use, the servo motor 6 drives the rotating seat 5 to rotate counterclockwise. The rotating seat 5 carries the swing arm assembly 7 to rotate around the center of the soaking tank 1 along the annular cam 3. When the swing arm assembly 7 rotates with the annular cam 3 to the high position of the annular cam 3, the swing arm assembly 7 floats on the water surface in the bottom of the annular tank 2. When the swing arm assembly 7 rotates with the annular cam 3 to the low position 8 of the cam, the label pressing assembly 9 can accurately press the swing arm assembly 7, so that the swing arm assembly 7 can be fully immersed in the water and the label can be fully soaked. In case of sudden shutdown, the swing arm lifting assembly 10 can support the swing arm assembly 7 to prevent the label from being damaged due to prolonged pressure.

[0052] The immersion tank structure disclosed in this embodiment, by setting up an immersion tank 1, a swing rod assembly 7, a label pressing assembly 9, and a swing rod lifting assembly 10, realizes efficient and automatic label immersion, effectively solving the problems of low yield and long time consumption in the traditional label immersion process. Thus, the immersion tank structure has the beneficial effects of high yield in the label immersion process, simple process, short time consumption, improved production efficiency, and optimized production process.

[0053] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Several hinge seats 11 are evenly installed on the outer wall of the rotating seat 5. Several rocker arm assemblies 7 each have a rocker arm 12. The end of the rocker arm 12 near the rotating seat 5 is hinged to the hinge seat 11. This allows the rocker arm assembly 7 to swing hingedly on the rotating seat 5 through the hinge seat 11. When the rocker arm assembly 7 rotates along the annular cam 3 from the higher position of the cam to the lower position of the cam 8, the setting of several hinge seats 11 causes the rocker arm assembly 7 to convert the rotational action into an up-and-down reciprocating action, thereby gradually immersing the rocker arm assembly 7 into water until it is completely submerged, thus achieving full immersion of the label.

[0054] The end of the swing arm 12 away from the rotating seat 5 is detachably connected to a label connecting rod 13. The end of the label connecting rod 13 away from the swing arm 12 is welded to a label base plate 14. The label base plate 14 has several through holes (not shown in the figure). The label connecting rod 13 and the swing arm 12 are connected to each other, which is conducive to the installation or replacement of the label base plate 14. It is convenient to install different models of label base plates 14 on the swing arm 12. The several through holes on the label base plate 14 are conducive to optimizing the water flow path, enhancing the uniformity of water immersion, and ensuring that the label is fully immersed and drained. When the swing arm assembly 7 moves from the lower cam 8 of the annular cam 3 to the higher cam, the excess water after the label is soaked will flow away through the through holes, ensuring that the label humidity is appropriate, so as to facilitate the separation of the label from the backing paper, and avoid the backing paper from sticking to the label due to excessive moisture content, thereby improving the label dryness and labeling effect.

[0055] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The top surface of the label base plate 14 is provided with a first label fixing block 15, a second label fixing block 16, a third label fixing block 17, and a fourth label fixing block 18 at four positions. The first label fixing block 15, the second label fixing block 16, the third label fixing block 17, and the fourth label fixing block 18 surround each other to form a receiving groove 19. The label is located in the receiving groove 19. The receiving groove 19 formed by the first label fixing block 15, the second label fixing block 16, the third label fixing block 17, and the fourth label fixing block 18 can accommodate the label to be immersed in water. Furthermore, the side of the first label fixing block 15, the second label fixing block 16, the third label fixing block 17, and the fourth label fixing block 18 closest to the receiving groove 19 can initially clamp the label to be immersed in water, thereby fixing the label in the initial immersion stage before it comes into contact with the label pressing assembly 9, effectively preventing the label from floating on the water surface.

[0056] The first label fixing block 15, the second label fixing block 16, the third label fixing block 17, and the fourth label fixing block 18 are slidably connected to the label base plate 14. Each of the first label fixing block 15, the second label fixing block 16, the third label fixing block 17, and the fourth label fixing block 18 has several oblong holes 20. Each of these blocks is connected to the label base plate 14 by screws passing through the oblong holes 20 and threaded onto the label base plate 14. The first label fixing block 15, the second label fixing block 16, the third label fixing block 17, and the fourth label fixing block 18 are slidably connected to the label base plate 14. After the first label fixing block 15, the second label fixing block 16, the third label fixing block 17, and the fourth label fixing block 18 are positioned on the label base plate 14 and fixed with screws, not only is the stability of the label during the water immersion process ensured, but the subsequent efficient removal of the label is also facilitated. At the same time, the cooperation between the screws and the oblong hole 20 allows the first label fixing block 15, the second label fixing block 16, the third label fixing block 17, and the fourth label fixing block 18 to adjust their displacement and lock, which facilitates changing the size of the receiving groove 19, thereby making the receiving groove 19 adaptable to various types of labels and meeting labeling requirements.

[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The label pressing assembly 9 has a horizontal support 21. The bottom surfaces of the two ends of the horizontal support 21 are vertically connected to a first column 22 and a second column 23. The ends of the first column 22 and the second column 23 away from the horizontal support 21 are connected to an arc-shaped pressing plate 24. The arc-shaped pressing plate 24 is submerged below the liquid level of the soaking tank 1. To prevent the labels from floating during the soaking process, the label pressing assembly 9 is set on one side of the cam low point 8 of the annular cam 3. When the swing arm assembly 7 rotates to the cam low point 8, the arc-shaped pressing plate 24 on the label pressing assembly 9 can accurately press the receiving tank 19. The receiving tank 19 is completely submerged in water, and the labels in it are also completely submerged in water, which can effectively prevent the labels from floating. This allows the labels to be soaked quickly, evenly and stably, which greatly improves the yield of the label soaking process, while significantly shortening the process time and improving the overall production efficiency.

[0058] The label pressing assembly 9 also has a motor (not shown in the figure) for driving the first column 22 and the second column 23 to rise and fall. A C-shaped frame 25 is connected to the outer side of the horizontal support 21. The end of the C-shaped frame 25 away from the horizontal support 21 is connected to the bottom of the soaking pool 1. The motor can drive the first column 22 and the second column 23 to rise, so that the swing arm lifting assembly 10 can push the swing arm assembly 7 immersed in the water out of the water surface. The C-shaped frame 25 can effectively suspend the horizontal support 21 above the annular pool bottom 2 corresponding to the low point 8 of the cam.

[0059] The swing arm lifting assembly 10 has a drive cylinder 26. A crescent-shaped top plate 27 is provided in the gap between the rotating seat 5 and the cam low 8 of the annular cam 3. The output shaft of the drive cylinder 26 is connected to a push plate 28. The side of the push plate 28 away from the drive cylinder 26 is vertically connected to a first top column 29 and a second top column 30 that are parallel to each other and spaced apart. The ends of the first top column 29 and the second top column 30 away from the push plate 28 are welded to the bottom surface of the crescent-shaped top plate 27. The drive cylinder 26 drives the crescent-shaped top plate 27 to lift and lower, thereby driving the swing arm assembly 7 to lift and lower as a whole. Under special working conditions, such as when the equipment suddenly stops, the motor drives the arc-shaped pressure plate 24 at the bottom of the first column 22 and the second column 23 away from the water surface. The swing arm lifting assembly 10 can act quickly to lift the swing arm assembly 7 above the water surface, preventing the label from being damaged or scrapped due to prolonged immersion, and effectively ensuring the integrity and usability of the label.

[0060] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Several support columns 31 are installed on the bottom surface of the annular pool bottom 2. One end of the support columns 31 is bolted to the bottom surface of the annular pool bottom 2, and the other end of the support columns 31 is bolted to the support platform (not shown in the figure). The support columns 31 effectively raise the soaking pool 1, which makes it easier to install the servo motor 6 at the bottom of the soaking pool 1.

[0061] The soaking tank 1 is equipped with an external water circulation temperature control system (not shown in the figure). This system has an outlet 32 ​​and an inlet 33, which are fixed to the annular bottom 2 and connected to the soaking tank 1. The outlet 32 ​​is connected to an outlet pipe (not shown in the figure), and the inlet pipe is connected to an inlet pipe (not shown in the figure). A water pump (not shown in the figure) and a heater (not shown in the figure) are connected between the outlet and inlet pipes. A filter (not shown in the figure) is installed on the inlet pipe. Several temperature sensors (not shown in the figure) are installed at the bottom of the soaking tank 1. These sensors are electrically connected to the water pump via a control board (not shown in the figure). When the temperature sensors detect a decrease in the water temperature in the soaking tank 1, the temperature sensors... The sensor transmits a signal to the control board, which then starts the water pump. The pump draws water from the outlet 32, and the water flows through the outlet pipe to the heater. The heater heats the water according to the temperature required by the label. The heated water then flows through the inlet pipe and filter into the soaking tank 1 from the inlet 33, thus circulating the water in the soaking tank 1. The heater can be preset with a water supply temperature according to the labeling process requirements, and can be precisely adjusted based on this setting to ensure that the output water temperature is kept constant within ±1℃. This improves the stability of the label adhesive and the firmness of the label. The filter can promptly remove impurities from the water in the soaking tank 1, maintaining the cleanliness and transparency of the water, preventing the label from getting stained, further improving the labeling quality, and ensuring the stable operation of the equipment in complex industrial environments.

[0062] The bottom of the rotating base 5 is provided with a motor frame 34, which is fixed on the support platform (not shown in the figure). The body of the servo motor 6 is bolted to the bottom surface of the motor frame 34. The output shaft of the servo motor 6 passes through the motor frame 34 and is connected to the axis of the bottom surface of the rotating base 5. The drive cylinder 26 is bolted to the outer side wall of the motor frame 34. The motor frame 34 provides an installation platform for the servo motor 6 and the drive cylinder 26.

[0063] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, a coaxial groove 35 is provided between the first label fixing block 15 and the third label fixing block 17. The arc-shaped pressure plate 24 adopts an arc-shaped design to ensure that when the rocker arm assembly 7 moves to the low cam 8 of the annular cam 3, the arc-shaped pressure plate 24 can smoothly slide through the groove 35 of the first label fixing block 15 and the third label fixing block 17. With the rounded curvature and precise size matching of the arc-shaped pressure plate 24, the arc-shaped pressure plate 24 can press the label just right during the sliding process. This stable pressing method effectively prevents the label from floating on the water surface due to buoyancy in the initial stage of immersion.

[0064] See Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 5 In this embodiment, a servo motor 6 drives the rotating seat 5. Each swing arm assembly 7 on the outer wall of the rotating seat 5 is configured to rotate around the central axis of the soaking tank 1 along the structure of the annular cam 3. Each swing arm assembly 7 includes a swing arm 12, a label connecting rod 13, and a label base plate 14 connected to one end of the label connecting rod 13. The receiving groove 19 of the label base plate 14 is used to place the label to be soaked. When the swing arm assembly 7 rotates along the annular cam 3 from the higher position of the cam to the lower position 8 of the cam, the receiving groove 19 is gradually immersed in the water until it is completely submerged, so as to achieve full soaking of the label. The rotation action is cleverly converted into an up-and-down reciprocating action. The rotation speed can be adjusted to control the soaking time of the label. In this technical solution, the label pressing assembly 9 is set in the water tank and located in the lower position 8 area of ​​the annular cam 3. When the swing arm assembly 7 rotates to this area, the label pressing assembly 9 is pressed on the receiving groove 19 to prevent the label from falling out of the receiving groove 19 due to buoyancy during the soaking process, thus ensuring the stability and consistency of the soaking effect. In addition, the immersion tank structure is also equipped with a swing arm lifting assembly 10. The drive cylinder 26 in the swing arm lifting assembly 10 drives the crescent-shaped top plate 27 to rise and fall, thereby driving the swing arm assembly 7 to rise and fall as a whole. Under special working conditions, such as when the equipment suddenly stops, the swing arm lifting assembly 10 can quickly lift the swing arm assembly 7 above the water surface to prevent the labels from being damaged or scrapped due to prolonged immersion, effectively ensuring the integrity and usability of the labels.

[0065] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the bottom inner sides of the first label fixing block 15, the second label fixing block 16, the third label fixing block 17 and the fourth label fixing block 18 can be attached to the label edge to fix the label in the initial immersion stage and before it comes into contact with the label pressing component 9, effectively preventing the label from floating on the water surface.

[0066] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The specific working principle of a water immersion tank structure in this embodiment is as follows:

[0067] First, in the soaking tank 1, several swing rod assemblies 7 rotate around the center of the soaking tank 1 along the annular cam 3. Each swing rod assembly 7 has a receiving groove 19, and the label is placed in the receiving groove 19. When the swing rod assembly 7 rotates with the annular cam 3 to the high position of the cam, the swing rod assembly 7 floats on the water surface. When the swing rod assembly 7 rotates with the annular cam 3 to the low position 8 of the cam, the receiving groove 19 is completely immersed in the water, so that the label is fully soaked in water.

[0068] Then, to prevent the labels from floating during immersion, the label pressing component 9 is positioned on one side of the cam low 8 of the annular cam 3. When the swing arm component 7 rotates to this position, the label pressing component 9 can accurately press down the receiving groove 19. In addition, in special circumstances, such as sudden machine stop, the swing arm lifting component 10 lifts the crescent-shaped top plate 27 through the drive cylinder 26, thereby lifting the swing arm component 7 and supporting the receiving groove 19, preventing the labels from being damaged due to prolonged pressure. Through this series of ingenious and coordinated mechanical components, this immersion tank structure achieves rapid, uniform and stable automatic immersion of labels, greatly improving the yield of the label immersion process, while significantly shortening the process time, providing solid technical support for improving overall production efficiency.

[0069] Finally, an innovative water circulation temperature control system is integrated into the water supply system of soaking tank 1. Users can preset the water supply temperature on the heater according to the labeling process requirements. The water supply system will adjust precisely according to the set value to ensure a constant output water temperature. Several high-precision temperature sensors are cleverly configured at the bottom of soaking tank 1 to monitor the water temperature in real time. Once the water temperature is detected to be lower than the preset temperature difference range, the system will automatically start the water circulation mode, and the heater will quickly raise the water temperature back to the set range. During the water circulation process, the filter works simultaneously to efficiently filter impurities in soaking tank 1, effectively preventing impurities from causing secondary contamination to the labels during circulation, ensuring the cleanliness of the labels and the labeling quality. This dynamic temperature control and circulation mechanism can not only significantly improve the label adhesion performance, but also minimize the potential impact of external environmental temperature fluctuations on the labeling quality, thereby ensuring the stability and high quality of the entire labeling process.

[0070] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In this embodiment, 1. the immersion tank structure has the significant advantage of efficiently loading and unloading labels while the equipment is running continuously, breaking through the bottleneck of frequent machine stops due to label loading and unloading in the traditional labeling process. It realizes full automation of the label from loading to immersion, significantly improving labeling efficiency, reducing manual intervention, and improving production continuity; 2. the swing arm assembly 7 and the annular cam 3 work together to realize automatic immersion of labels for different durations, flexibly meeting diverse process requirements and realizing the control of label immersion time. This effectively breaks through the constraints of traditional technology and significantly improves the flexibility and adaptability of the label immersion process; 3. precise temperature control and stability, through the independently controlled immersion structure and water circulation temperature control system, strictly control water temperature fluctuations. Within ±1℃, the stability of label adhesive is significantly improved, enhancing label adhesion. The optimized water tank design, combined with efficient water circulation, ensures uniform water distribution, controlling temperature unevenness within ±2℃, guaranteeing uniform label soaking and improving labeling quality. 4. The label base plate 14 can be replaced according to the process requirements of different label materials (flexible setting of draining time), effectively improving label dryness and labeling effect. 5. The swing arm assembly 7 is set separately, without affecting other label receiving tanks 19 and the operation of the whole machine, effectively ensuring production efficiency and equipment operation stability. 6. The filter can promptly remove impurities in the soaking tank 1, maintaining water cleanliness and transparency, preventing labels from being stained, further improving labeling quality, and ensuring stable operation of the equipment in complex industrial environments.
