Description

Technical Field

[0001] The invention relates to the technical field of film label production, in particular to a processing technology and production equipment for a washable film pressure-sensitive adhesive label. Background Art

[0002] Pressure-sensitive labels, also known as self-adhesive labels or self-adhesive labels, are plastic or paper labels with adhesive pre-coated on the back, which can be firmly attached to the surface of the package. Its "pressure-sensitive" property means that the label will adhere to the surface of the object when pressure is applied. Pressure-sensitive labels are widely used for labeling a variety of rigid plastic, glass and cardboard round containers and a variety of flexible packaging bags. Pressure-sensitive labels come in a variety of forms to suit different application needs. For example, there are single-sheet labels suitable for manual application, and roll labels suitable for mechanical application on high-speed production lines. In order to ensure that the adhesive is activated at the right time, a protective plastic-coated release paper is usually used to cover the adhesive surface area. The raw materials of pressure-sensitive labels mainly include face material, glue and backing paper. The face material is the outside of the label and can be made of various types of paper or plastic film to allow for the printing of graphics and text. Glue is responsible for the adhesion between the label and the object, and the common type of glue is acrylic series glue. The backing paper plays a supporting role in the label production process to ensure the integrity of the label during processing and storage. The processing of pressure-sensitive labels includes coating, drying and slitting. The coating process evenly coats the glue on the surface material, and the drying process allows the glue to fully shrink to increase the adhesion with the base paper. Finally, the slitting process cuts the label paper into the required size and shape.

[0003] The Chinese patent document with patent number CN202222826003.3 discloses a pressure-sensitive label substrate gluing device, which relates to the technical field of pressure-sensitive label production, and in particular to a pressure-sensitive label substrate gluing device, comprising a feed pipe and a conveyor belt, the lower end face of the feed pipe is fixedly connected to a material storage box, the middle upper end face of the material storage box is fixedly connected to a first motor, the lower end face of the first motor is fixedly connected to a motor shaft, the lower end face of the motor shaft is fixedly connected to a stirring blade, and an electric heating copper tube is arranged on the outside of the material storage box; in the present invention, by providing the first motor, the motor shaft, the stirring blade and the electric heating copper tube, the device can heat and fully stir the glue in the material storage box, prevent the glue in the material storage box from being stationary for a long time and the temperature outside the material storage box is too low, causing the glue to solidify, so as to solve the problem that the glue is prone to solidification when it is left stationary in the material storage box.

[0004] In the above patent document, in the process of making pressure-sensitive labels, the glue is applied by extracting the glue through an extraction pump and injecting it into the surface of a brush. After the glue is applied to the label board by a brush, it is air-dried by an air-drying component. This makes it possible for the glue on the brush to solidify automatically during the application process, and after the glue is applied, it needs to be dried through a longer drying production line. At the same time, the amount of glue used is large, and it is difficult for the glue to maintain stable fluidity during the application process. This makes it easy for the glue to dry out or over-apply when applying and drying the glue. Summary of the invention

[0017] 2. The washable film pressure-sensitive adhesive label production equipment, through the setting of the angle adjustment component, enables the adhesive roller to independently adjust the height between the adhesive roller and the upper bottom plate, and cooperates with the lifting component to adjust the height of the support roller, so that the device can quickly adjust the tension of the label paper during the adhesive application process. If the lateral distance and vertical distance between the adhesive roller and the support roller are different, the tightness of the label paper mounted on the adhesive roller and the support roller will also be different, so that the device can be suitable for the use of label paper of different materials.

[0018] 3. The washable thin film pressure-sensitive adhesive label production equipment, through the setting of the air-drying component, enables the device to quickly air-dry the label paper after being glued, and uses the air-drying plate to perform hot air air-drying on the label paper laid on the expansion rod, so that the device can continuously air-dry the label paper. When the wind in the air-drying plate blows toward the label paper, the expansion rod guides the label paper into a triangular shape convex toward the air-drying plate, so that the hot air in the air-drying plate is divided into two groups, upper and lower, which are blown toward the surface of the label paper entering the air-drying component and flowing out of the air-drying component respectively, and the hot air can better contact with the glue attached to the surface of the label paper, thereby improving the air-drying efficiency of the label paper.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A lower bottom plate 7 is provided at the lower end of the upper bottom plate 1. A support member is provided between the lower bottom plate 7 and the upper bottom plate 1. A film-applying component 8 is provided on the lower bottom plate 7. After being air-dried, the label paper 9 enters the film-applying component 8 to be laminated with the label film, and is rolled and unloaded after film-applying.

[0023] The upper bottom plate 1 is the main supporting part of the equipment, and its right side is connected to the air-drying component 2. The air-drying component 2 includes an expansion rod 201, a fixing part 202 and an air-drying plate 203. The expansion rod 201 can adjust the angle of the air-drying plate 203 to meet different air-drying requirements. The adhesive roller 3 is installed on the upper bottom plate 1 and is fixed and angle-adjusted by an angle adjustment component 4 (such as a swing arm 401 and a rotating shaft 402). The outer wall of the adhesive roller 3 is provided with a glue discharge hole, and the inner cavity is a glue storage cavity 301. The wall surface of the glue storage cavity 301 is provided with a glue outlet notch 302 opposite to the direction of the adhesive roller 3, which is used to evenly apply glue. The lower bottom plate 7 is located below the upper bottom plate 1, and the two are connected by a support to ensure the stability of the equipment. It is located on the right side of the adhesive roller 3 and is used to support and guide the movement of the label paper 9. The film sticking component 8 is arranged on the lower bottom plate 7, including a support plate 801, an interlayer roller 802 and a placement roller 803. After the label paper 9 is air-dried, it is bonded to the label film in the film bonding assembly 8 .

[0024] After the unprocessed label paper 9 passes through the adhesive roller 3, it bypasses the support roller 5 and enters the air-drying component 2. After passing through the air-drying component 2, it is bonded to the label film set on the placement roller 803, and finally passes through the interlayer roller 802 and is wound on the winding device. Start the equipment, drive the winding device to operate, and drive the label paper 9 and the label film to move synchronously. Glue is supplied to the inner cavity of the adhesive roller 3, and the adhesive roller 3 rotates under the drag of the label paper 9. The glue is evenly coated on the label paper 9 through the glue outlet slot 302 and the glue discharge hole. The glue-coated label paper 9 enters the air-drying component 2 for air drying. The air-dried label paper 9 is bonded to the label film in the film-applying component 8, and finally rolled up by the winding device to complete the production of the pressure-sensitive adhesive label.

[0025] The equipment has a high degree of automation and can achieve continuous and efficient label production. The glue roller 3 and the angle adjustment component 4 are used in conjunction to ensure that the glue is evenly coated on the label paper 9. The air drying component 2 can quickly and effectively remove excess glue on the label paper 9 to improve product quality. The film laminating component 8 can ensure the precise lamination of the label paper 9 and the label film to reduce the scrap rate. All parts of the equipment can be flexibly adjusted to adapt to the production of labels with different specifications and requirements.

[0026] See also Figure 3-Figure 4The film laminating assembly 8 includes a support plate 801 , two sandwich rollers 802 are arranged between the support plates 801 , a placement roller 803 is arranged at the bottom of the support plate 801 , a label film is arranged on the placement roller 803 , and the label paper 9 and the label film are laminated through the sandwich roller 802 .

[0027] Through the setting of two interlayer rollers 802, the label paper 9 and the label film can be subjected to uniform and stable pressure when passing through the interlayer roller 802, ensuring that the two can be accurately attached, reducing quality problems such as bubbles and misalignment, and improving the overall quality of the label. The design of the interlayer roller 802 makes the label paper 9 and the label film attaching process smoother, improving production efficiency. At the same time, the rotation of the interlayer roller 802 helps the label paper 9 and the label film to be better aligned during the attaching process, further ensuring production efficiency. The setting of the placement roller 803 makes the replacement of the label film simple and quick, without the need for complex operations or adjustments, reducing the difficulty of operation and improving the ease of use of the equipment. By adjusting the distance and angle between the interlayer rollers 802, the film assembly 8 can adapt to label papers 9 and label films of different thicknesses and sizes, enhancing the adaptability and flexibility of the equipment. Since accurate attachment can be achieved, the generation of waste products caused by poor attachment is reduced, and the production cost is reduced. The interlayer roller 802 and the placement roller 803 are both detachable parts, which are convenient for cleaning, maintenance and replacement, and extend the service life of the equipment.

[0028] The sandwich roller 802 is slidably connected to the support plate 801. The gap between the two sandwich rollers 802 can be adjusted to achieve different degrees of adhesion of the label film.

[0029] See also Figure 5-Figure 6 The angle adjustment component 4 includes two swing arms 401 arranged front and rear on the upper base plate 1, the two swing arms 401 are connected by a rotating shaft 402, the rotating shaft 402 is connected to a driving motor 403, the glue roller 3 is installed between the two swing arms 401, and a glue inlet hole is provided on the swing arm 401 to communicate with the inner cavity of the glue roller 3, and the glue inlet hole is connected to the glue supply device through a glue inlet pipe.

[0030] Since the glue inlet hole provided on the swing arm 401 is connected to the inner cavity of the glue roller 3, the glue can be directly delivered to the inside of the glue roller 3 through the glue inlet pipe. This design ensures that the glue can be evenly distributed on the surface of the glue roller 3, thereby achieving a stable glue attachment effect. The automated control of the angle adjustment component 4 reduces the need for manual intervention, reduces the difficulty of operation, and improves production efficiency. At the same time, the precise angle adjustment and stable glue attachment effect also reduce the scrap rate in the production process, further improving production efficiency. Since the angle adjustment component 4 adopts a mechanized and automated design, the failure rate and wear degree of the equipment are reduced. In addition, the durability of key components such as the swing arm 401 and the glue roller 3 is also enhanced, thereby reducing the maintenance cost of the equipment. The angle adjustment component 4 and its related configurations can be widely used in various fields requiring angle adjustment and glue attachment processing, such as printing, coating, laminating and other industries. Its flexibility and stability enable these devices to adapt to different production processes and product requirements.

[0031] The support roller 5 is fixedly installed by the lifting assembly 6. Through the setting of the angle adjustment assembly 4, the adhesive roller 3 can autonomously adjust the height between the upper bottom plate 1, and the lifting assembly 6 adjusts the height of the support roller 5, so that the device can quickly adjust the tension of the label paper 9 during the adhesive process. If the horizontal distance and vertical distance between the adhesive roller 3 and the support roller 5 are different, the tension of the label paper 9 mounted on the adhesive roller 3 and the support roller 5 is also different, so that the device can be suitable for the use of label paper 9 of different materials.

[0032] See also Figure 7-Figure 9 The outer wall of the adhesive roller 3 is provided with adhesive discharge holes, the inner cavity of the adhesive roller 3 is provided with an adhesive storage cavity 301, the wall surface of the adhesive storage cavity 301 is provided with an adhesive outlet slot 302 in the opposite direction of the adhesive roller 3, and a adhesive outlet gap is left between the adhesive storage cavity 301 and the wall surface of the adhesive roller 3; The glue discharge holes arranged on the outer wall of the adhesive roller 3 ensure that the glue can be evenly distributed on the roller surface. The layout and quantity of these holes can be adjusted according to actual needs to achieve a finer glue distribution. The position and size of the glue discharge holes are precisely designed to play a diversion role when there is too much glue, prevent glue accumulation and overflow, and ensure the stability and consistency of the coating process. The glue storage cavity 301 is used to store glue to ensure the continuity and stability of the glue supply during the coating process. The design of the cavity can optimize the storage and flow properties of the glue and reduce the generation of bubbles and impurities. The glue outlet notch 302 arranged on the wall of the glue storage cavity 301 is opposite to the direction of the adhesive roller 3. This design can ensure that the glue is effectively squeezed and pushed out during the rotation of the roller, thereby improving the utilization rate of the glue and the coating effect. The glue outlet gap left between the glue storage cavity 301 and the wall of the adhesive roller 3 is a channel for the glue to flow from the cavity to the roller surface. The size and shape of this gap are precisely calculated and designed to ensure that the glue can flow out evenly and be distributed on the roller surface.

[0033] See also Figure 10-11 The air-drying component 2 includes an expansion rod 201, which is clamped in the oblique slide groove on the fixing member 202. The fixing member 202 is connected to the upper base plate 1. An air-drying plate 203 is arranged between the fixing members 202, and the air-drying plate 203 is connected to the fixing member 202 through a rotating bearing.

[0034] The expansion rod 201 is clamped in the oblique slide groove on the fixing member 202. This design allows the air-drying component 2 to be adjusted within a certain range in the vertical direction. The oblique slide groove can ensure that the expansion rod 201 remains stable when moving, and the height and angle of the air-drying plate 203 can be adjusted as needed. The design of the expansion rod 201 may also allow the air-drying component 2 to be fine-tuned in the horizontal direction to adapt to workpieces of different sizes or shapes and ensure a more uniform air-drying effect. The fixing member 202 is connected to the upper base plate 1 to provide a stable support structure for the air-drying component 2. This connection method can ensure the stability of the air-drying component 2 during the air-drying process and prevent displacement caused by vibration or external factors. At the same time, the connection between the fixing member 202 and the upper base plate 1 can also be easily disassembled and installed, which is convenient for maintenance and replacement of the equipment. The air-drying plate 203 is connected to the fixing member 202 through a rotating bearing. This design allows the air-drying plate 203 to be rotated and adjusted within a certain range. The rotating bearing ensures the stability and smoothness of the air-drying plate 203 during the rotation process, while reducing friction and wear. By adjusting the rotation angle of the air-drying plate 203, the air-drying effect on different surfaces of the workpiece can be achieved, thereby improving the uniformity and efficiency of air-drying.

[0035] The air-drying plate 203 is provided with air-drying holes arranged at equal intervals, and the air-drying plate 203 is connected to an air blowing device.

[0036] Since the air-drying holes are arranged equidistantly on the air-drying plate 203, the airflow generated by the air-blowing device can pass through these holes evenly and thus be evenly distributed on the surface of the workpiece to be air-dried. This ensures that every part of the workpiece surface can be fully dried, avoiding quality problems caused by insufficient or excessive local air-drying. The evenly distributed airflow can accelerate the evaporation rate of the water on the surface of the workpiece, thereby significantly shortening the air-drying time. This is of great significance for improving production efficiency and reducing energy consumption, especially in mass production or continuous production lines. Since the air-drying holes are arranged equidistantly, the air-drying plate 203 can adapt to workpieces of different sizes and shapes. By simply adjusting the distance and angle between the air-drying plate and the workpiece, it can be ensured that the airflow can fully cover the entire workpiece surface and achieve comprehensive air-drying. This design enhances the versatility and flexibility of the equipment. The design of the air-drying holes makes the air-drying plate 203 easy to clean and maintain. When cleaning is required, the accumulated dust and impurities can be removed by reverse blowing or disassembling the air-drying plate to keep the equipment in good operating condition. In addition, regular cleaning can also prevent impurities from blocking the air-drying holes and affecting the air-drying effect. By optimizing the layout of the air-drying holes and coordinating with the air-blowing device, energy can be used more efficiently and unnecessary energy consumption can be reduced. At the same time, the uniform air-drying effect also reduces the exhaust gas and wastewater emissions caused by excessive air-drying, which helps to reduce environmental pollution and achieve sustainable development.

[0037] See also Fig.12 After the label paper 9 is glued, it enters the air-drying component 2 for air-drying. The heat flow in the air-drying plate 203 blows toward the label paper 9, and the heat flow is divided into two streams to air-dry the label paper 9. The air-dried label paper 9 is attached to the label film through the film-attaching component 8 to complete the preparation of the entire label paper 9.

[0038] The washable film pressure-sensitive adhesive label processing process includes the following steps: Step 1: After the unprocessed label paper 9 passes through the adhesive roller 3, it bypasses the support roller 5 and enters the air-drying component 2. After passing through the air-drying component 2, it is bonded to the label film set on the placement roller 803, passes through the interlayer roller 802, and finally winds on the winding device to complete the fixed overlap of the label paper 9; through the precisely controlled steps of adhesive, air drying, bonding, etc., it is ensured that the adhesion between the label paper and the label film is firm, without bubbles or gaps, and the product quality is improved. Reduce production costs: The automated production process reduces manpower input and error rate, while optimizing material use and energy consumption, which helps to reduce production costs.

[0039] Step 2: driving the winding device to move the label paper 9 and the label film; Step 3: Adjust the angle of the swing arm 401 and the support height of the support roller 5 to ensure that the label paper 9 is at a reasonable tension. The angle of the swing arm 401 and the height of the support roller 5 jointly determine the tension of the label paper during the transmission process. Appropriate tension helps to keep the label paper flat and stable and avoid quality problems during the processing. By adjusting these two parameters, the tension can be accurately controlled to meet different production needs.

[0040] Step 4: Glue is supplied to the inner cavity of the glue-attaching roller 3. The glue-attaching roller 3 rotates under the drag of the label paper 9. The glue supplied into the glue-attaching roller 3 is discharged through the glue outlet notch 302 to attach glue to the label paper 9. Step 5: The label paper 9 with glue attached enters the air-drying component 2, and the glue on the label paper 9 is air-dried by adjusting the angle of the air-drying plate 203; Step six, the air-dried label paper 9 is attached to the label film through the film sticking assembly 8, and finally rolled up by the rolling device to complete the production of the pressure-sensitive adhesive label.

[0041] The air-drying holes arranged equidistantly on the air-drying plate 203 can ensure that the airflow is evenly distributed on the surface of the workpiece, thereby achieving a more uniform air-drying effect. This design avoids the situation of local over-drying or insufficient air-drying, and improves product quality and consistency. The reasonable layout of the air-drying holes and the cooperation of the air-blowing device can accelerate the evaporation rate of the water on the surface of the workpiece and shorten the air-drying time. This is of great significance for improving production efficiency and reducing energy consumption. Since the air-drying holes are arranged equidistantly, the air-drying plate 203 can adapt to workpieces of different sizes and shapes. By adjusting the distance and angle between the air-drying plate 203 and the workpiece, it can be ensured that the airflow can fully cover the entire workpiece surface and achieve comprehensive air-drying.

[0042] Working principle: During the operation of the device, glue is supplied to the inner cavity of the glue roller 3, and the forward and reverse rotation of the glue roller 3 is controlled to achieve the purpose of glue discharge or non-discharge. When glue is required, the glue roller 3 is driven to rotate, and the rotation direction of the glue roller 3 is opposite to the glue discharge slot 302 in the inner cavity of the glue roller 3. Figure 7 , the glue is discharged, and the angle adjustment component 4 can reasonably adjust the relative position between the glue roller 3 and the support roller 5 to ensure that the tension of the label paper 9 during the gluing process can be maintained within a certain range. When the label paper 9 is glued, it enters the air drying component 2 for air drying, and the heat flow in the air drying plate 203 blows toward the label paper 9, such as Fig.10 As shown, the heat flow is divided into two streams to air-dry the label paper 9 , and the air-dried label paper 9 is attached to the label film through the film sticking assembly 8 , thereby completing the preparation of the entire label paper 9 .
