Description

Technical Field

[0001] This utility model relates to the field of film tape processing technology, specifically a dust removal device for adhesion rollers in the pre-coating process of lens PET film tape. Background Technology

[0002] In the production of PET film tape for lenses, the coating process is one of the key steps. The quality of the coating directly affects the performance and lifespan of the tape. However, before coating, the tape surface often contains dust, impurities, and other contaminants. If these contaminants are not removed, they will cause defects during the coating process, leading to decreased tape adhesion, poor appearance quality, and even affecting its optical and electronic properties. Therefore, effective surface cleaning of the tape is an important prerequisite for ensuring coating quality.

[0003] While there are some automated cleaning devices on the market, most of them suffer from the following problems:

[0004] The inability to achieve continuous production means that many devices need to be frequently stopped for maintenance or replacement of cleaning parts during the cleaning process, resulting in low production efficiency and failing to meet the needs of continuous production.

[0005] In existing dust removal equipment, dust removal components (such as adhesion rollers) accumulate a lot of dust on their surface after a period of use. If they are not cleaned in time, it will affect their cleaning effect. However, most existing cleaning equipment lacks an effective automatic dust removal function and requires manual cleaning on a regular basis, which increases labor intensity and maintenance costs. Utility Model Content

[0006] The purpose of this invention is to provide a dust removal device for the adhesion roller in the pretreatment of lens PET film tape coating, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dust removal device for adhesion rollers in the pretreatment of PET film adhesive tape coating for lenses includes a machine base and a rotating shaft. The rotating shaft is horizontally rotatably mounted on the machine base, and multiple tension rollers are horizontally rotatably mounted on the machine base. The multiple tension rollers are evenly and symmetrically arranged on both sides of the rotating shaft.

[0009] The rotating shaft is equipped with four sets of elastic dust removal components, which are evenly distributed along the circumference. One end of the membrane tape passes through multiple tension rollers in sequence and is connected to the collection device. Three of the sets of elastic dust removal components are in close contact with the membrane tape for dust removal.

[0010] The machine is equipped with a cleaning component, which is attached to another set of elastic dust removal components and is used to remove dust adhering to the elastic dust removal components.

[0011] The machine is equipped with a drive assembly, which is connected to the rotating shaft and the cleaning assembly respectively. When the drive assembly is running, the cleaning assembly will work continuously. At the same time, the rotating shaft will drive the four sets of elastic dust removal assemblies to rotate intermittently by 90 degrees, so that each set of elastic dust removal assemblies can cooperate with the cleaning assembly at intervals to complete the ash removal process.

[0012] As a further embodiment of this utility model:

[0013] The elastic dust removal assembly includes a sleeve and a slide bar, wherein the sleeve is fixed to the circumferential surface of the rotating shaft;

[0014] The slide rod is slidably engaged with the sleeve, and a spring is provided inside the sleeve.

[0015] As a further improvement of this utility model:

[0016] The two ends of the spring abut against the inner walls of the slide rod and the sleeve, respectively, so as to drive the slide rod to always have an outward tendency;

[0017] The end of the slide bar is equipped with a dust-adhesive roller that rotates horizontally, and the dust-adhesive roller is in close contact with the film tape.

[0018] As a further improvement of this utility model:

[0019] The cleaning assembly includes two horizontally rotating rods mounted on the machine platform, and the two rotating rods are symmetrically arranged about the rotating axis.

[0020] Both rotating rods are coaxially equipped with roller brushes, and both roller brushes are in contact with the dust-adhesive roller. A collection box is provided on the machine base, and the collection box is located below the two roller brushes.

[0021] As a further improvement of this utility model:

[0022] The drive assembly includes a driving disk and a driven disk, which cooperate with each other;

[0023] When the driving disk rotates, the driven disk will rotate intermittently under the drive of the driving disk.

[0024] As a further improvement of this utility model:

[0025] The driven disk is coaxially mounted on the rotating shaft, and the driving disk is rotatably mounted on the machine base via a transmission shaft.

[0026] The machine base is equipped with a motor, and the output end of the motor is coaxially and fixedly connected to one end of the transmission shaft.

[0027] As a further improvement of this utility model:

[0028] A drive pulley is coaxially mounted on the drive shaft, and driven pulleys are coaxially mounted on both rotating rods. The drive pulley and the two driven pulleys are connected by a toothed belt.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] By setting multiple sets of flexible dust removal components to fit tightly with the membrane tape, dust and impurities on the surface of the membrane tape can be effectively removed, improving the cleanliness of the membrane tape, providing a high-quality surface for subsequent coating processes, reducing defects and flaws caused by dust during the coating process, and improving the quality of the final product.

[0031] The combined design of the sweeping component and the flexible dust removal component can promptly remove dust adhering to the flexible dust removal component, preventing dust from accumulating on the dust removal component, ensuring that the dust removal component always maintains a good cleaning effect, extending its service life, and further improving dust removal efficiency and quality.

[0032] The drive component configuration enables continuous operation of the sweeping component and intermittent rotation of the flexible dust removal component driven by the rotating shaft. This allows each set of flexible dust removal components to work evenly with the sweeping component to complete the dust removal process, avoiding damage caused by excessive use in certain areas, further balancing the service life of each component, and reducing the maintenance cost of the equipment.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0042] Please see Figures 1-6 In this embodiment of the present invention, a dust removal device for adhesion rollers in the pretreatment of PET film adhesive tape coating for lenses includes a machine base 1 and a rotating shaft 2. The rotating shaft 2 is horizontally rotatably mounted on the machine base 1, and a plurality of tension rollers 3 are horizontally rotatably mounted on the machine base 1. The plurality of tension rollers 3 are evenly and symmetrically arranged on both sides of the rotating shaft 2.

[0043] The rotating shaft 2 is equipped with four sets of elastic dust removal components. The four sets of elastic dust removal components are evenly distributed along the circumference. One end of the membrane tape passes through multiple tension rollers 3 in sequence and is connected to the collection device. Three of the sets of elastic dust removal components are in close contact with the membrane tape for dust removal.

[0044] The machine 1 is equipped with a cleaning component, which is attached to another set of elastic dust removal components and is used to remove dust adhering to the elastic dust removal components.

[0045] The machine 1 is equipped with a drive assembly, which is connected to the rotating shaft 2 and the cleaning assembly respectively. When the drive assembly is running, the cleaning assembly will work continuously. At the same time, the rotating shaft 2 will drive the four sets of elastic dust removal assemblies to rotate intermittently by 90 degrees, so that each set of elastic dust removal assemblies can cooperate with the cleaning assembly at intervals to complete the ash removal process.

[0046] In this scheme, before the equipment is started, one end of the membrane tape passes through multiple tension rollers 3 in sequence and is finally connected to the collection equipment. At this time, four sets of elastic dust removal components are evenly distributed on the rotating shaft 2. Three of them are in close contact with the membrane tape and are ready to perform dust removal operations; the other set is in contact with the cleaning component and is in a state of waiting to be cleaned. The drive component is in a standby state and is ready to drive the rotating shaft 2 and the cleaning component to run.

[0047] As the equipment starts, the membrane tape is smoothly transported along the set path under the guidance of the tension roller 3. The tension roller 3 is evenly and symmetrically arranged on both sides of the rotating shaft 2 to ensure that the membrane tape maintains stable tension during the transport process and avoids slack or wrinkles.

[0048] Three sets of elastic dust removal components, which are in close contact with the membrane tape, begin to remove dust from the surface of the membrane tape. The elastic dust removal components use their own adhesiveness or adsorption to adsorb and remove dust and impurities from the surface of the membrane tape, thereby achieving effective cleaning of the membrane tape. During this process, the elastic dust removal components maintain close contact with the membrane tape to ensure the dust removal effect.

[0049] At the same time, the drive component starts to run, the cleaning component starts and continues to work, and the cleaning component comes into contact with another set of flexible dust removal components to remove the dust adhering to the flexible dust removal components.

[0050] During the continuous operation of the cleaning component, the drive component simultaneously controls the rotating shaft 2 to rotate intermittently by 90 degrees. After each 90-degree rotation, a set of elastic dust removal components that were originally in close contact with the membrane tape will move to the position of the cleaning component, come into contact with the cleaning component, and begin the dust removal operation; while the elastic dust removal components that were originally in the dust removal state will move to the position in contact with the membrane tape and participate in the dust removal operation again. Through this intermittent rotation, the four sets of elastic dust removal components can take turns to perform dust removal and dust removal, ensuring that each set of components can complete the dust removal process within a certain time interval, and always maintain a good cleaning effect.

[0051] During operation, the membrane belt is continuously transported, and three sets of elastic dust removal components continuously remove dust from the membrane belt; at the same time, the cleaning component continuously cleans the other set of elastic dust removal components; the rotating shaft 2 continuously adjusts the position of each elastic dust removal component according to the set intermittent 90-degree rotation pattern, so that it cycles between dust removal and cleaning.

[0052] As a further embodiment of this utility model, the elastic dust removal assembly includes a sleeve 4 and a sliding rod 5, wherein the sleeve 4 is fixed to the circumferential surface of the rotating shaft 2;

[0053] The slide rod 5 is slidably engaged with the sleeve 4, and a spring 6 is provided inside the sleeve 4;

[0054] The two ends of the spring 6 abut against the inner walls of the slide rod 5 and the sleeve 4 respectively, so as to drive the slide rod 5 to always have an outward tendency;

[0055] The end of the slide bar 5 is horizontally rotatably equipped with a dust-adhesive roller 7, which is in close contact with the film tape.

[0056] In this embodiment, when the film tape is conveyed under the guidance of the tension roller 3, the dust-adhesive roller 7 adsorbs dust and impurities on the surface of the film tape through the adhesive material on its surface. Since the dust-adhesive roller 7 is closely attached to the film tape and can adapt to the slight changes on the surface of the film tape, it can efficiently remove dust from the surface of the film tape.

[0057] The function of spring 6 is to provide an outward elastic force. Since the two ends of spring 6 abut against the inner wall of slide rod 5 and sleeve 4 respectively, spring 6 always applies an outward pushing force to slide rod 5. This pushing force makes slide rod 5 maintain an outward tendency within sleeve 4, thereby enabling the adhesive roller 7 to adhere tightly to the surface of the film tape.

[0058] As a further embodiment of this utility model, the cleaning assembly includes two horizontally rotating rods 8 mounted on the machine base 1, and the two rotating rods 8 are symmetrically arranged about the rotating shaft 2 as the center.

[0059] Both rotating rods 8 are coaxially equipped with roller brushes 9, and both roller brushes 9 are in contact with the dust-adhesive roller 7. A collection box 10 is provided on the machine base 1, and the collection box 10 is located below the two roller brushes 9.

[0060] In this embodiment, when the elastic dust removal assembly rotates to the cleaning assembly position, the sticky roller 7 is in close contact with the two roller brushes 9. The roller brushes 9 contact the surface of the sticky roller 7 through their soft bristles, which can effectively remove the dust and impurities adhering to the surface of the sticky roller 7.

[0061] The rotating rod 8 rotates horizontally under the drive of the drive component, thereby driving the roller brush 9 to rotate; the rotation of the roller brush 9 causes the bristles to form rolling friction on the surface of the sticky roller 7, further enhancing the cleaning effect. This rolling friction can not only remove dust from the surface of the sticky roller 7, but also avoid damage to the surface of the sticky roller 7.

[0062] During the cleaning process, the dust removed by the roller brush 9 will fall due to gravity. Since the collection box 10 is located below the two roller brushes 9, the falling dust will fall directly into the collection box 10, thereby achieving effective collection and centralized treatment of dust.

[0063] When the rotating shaft 2 drives the elastic dust removal components to rotate intermittently by 90 degrees, each set of elastic dust removal components will cooperate with the cleaning components in turn. After each rotation, a set of sticky rollers 7 enters the cleaning position, sticks to the roller brush 9 and performs cleaning operations, while the other sets of sticky rollers 7 continue to perform dust removal operations.

[0064] As a further embodiment of this utility model, the drive assembly includes a driving disk 11 and a driven disk 12, the driving disk 11 and the driven disk 12 cooperating with each other;

[0065] When the driving disk 11 rotates, the driven disk 12 will rotate intermittently under the drive of the driving disk 11;

[0066] The driven disk 12 is coaxially mounted on the rotating shaft 2, and the driving disk 11 is rotatably mounted on the machine base 1 via the transmission shaft 13;

[0067] The machine base 1 is equipped with a motor 14, and the output end of the motor 14 is coaxially and fixedly connected to one end of the transmission shaft 13.

[0068] A drive pulley 15 is coaxially mounted on the drive shaft 13, and driven pulleys 16 are coaxially mounted on both rotating rods 8. The drive pulley 15 and the two driven pulleys 16 are connected by a toothed belt 17.

[0069] In this embodiment, when the device is started, the output end of the motor 14 begins to rotate, and the rotation of the motor 14 is transmitted to the drive disc 11 and the drive pulley 15 through the drive shaft 13;

[0070] Driven by the motor 14, the drive disc 11 begins to rotate; the drive disc 11 and the driven disc 12 together form a Maltese cross mechanism, which causes the driven disc 12 to rotate intermittently under the drive of the drive disc 11. The purpose of this intermittent rotation is to achieve 90-degree intermittent rotation of the elastic dust removal components on the rotating shaft 2, so that each set of elastic dust removal components can cooperate with the cleaning components in turn to perform dust removal operations.

[0071] The driven disk 12 is coaxially fixed on the rotating shaft 2. Therefore, the intermittent rotation of the driven disk 12 directly drives the rotating shaft 2 to rotate intermittently by 90 degrees. Each time the rotating shaft 2 rotates 90 degrees, one set of elastic dust removal components moves from the dust removal position to the cleaning position, and another set moves from the cleaning position to the dust removal position. This position adjustment ensures that each set of elastic dust removal components can complete the dust removal process within a certain time interval, maintaining a good cleaning effect.

[0072] The rotation of motor 14 not only drives the drive disc 11 to rotate, but also transmits power through the drive pulley 15 on the transmission shaft 13. The drive pulley 15 is connected to two driven pulleys 16 through toothed belt 17, thereby driving the two driven pulleys 16 to rotate.

[0073] The driven pulley 16 is coaxially fixed on the rotating rod 8. Therefore, the rotation of the driven pulley 16 drives the rotating rod 8 to rotate continuously. The rotation of the rotating rod 8 causes the roller brush 9 to rotate continuously, thereby realizing the continuous cleaning operation of the dust roller 7.

[0074] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0075] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
