TECHNICAL FIELD
[0001] The present application relates to the technical field of adhesive tape production, and in particular to a purification and dust removal device for adhesive tape production. BACKGROUND
[0002] In the production process of adhesive tape, the raw material film is prone to generate static electricity during high-speed coating, slitting and winding processes. This static electricity not only directly attracts dust, fibers and other small particles in the ambient air, resulting in impurities, black spots or white spots on the surface of the finished adhesive tape, which seriously affects the appearance purity, light transmittance and bonding performance of the adhesive tape. More seriously, in high-end application fields such as electronic adhesive tape or optical adhesive tape, any static electricity residue may cause inaccurate positioning, spark discharge risk and performance degradation during the later die-cutting, lamination and filling processes. Therefore, effectively removing static electricity and attached dust from the surface of the adhesive tape is a key link to ensure product quality.
[0003] The current industry generally uses dust removal solutions that have the following disadvantages: single ion air blower cannot evenly cover the static electricity removal effect and is difficult to adapt to the surface of the high-speed moving and fluctuating adhesive tape; pure negative pressure dust removal cannot completely remove the fine dust tightly attracted by static electricity, and may leave cleaning dead angles; and the fixed dust sticking roller can supplement the removal of some surface particles, but needs to be replaced frequently, affecting production efficiency, and itself may also become a source of pollution. In addition, the air inlet filter device introduced to protect the internal equipment from environmental dust is difficult to monitor the filter screen blockage in real time, and untimely maintenance may form secondary pollution hazards or increase wind resistance energy consumption; therefore, we propose a purification and dust removal device for adhesive tape production to solve this problem.

[0013] The present application has the following beneficial effects: 1. In this invention, a dust removal and purification device for tape production involves feeding the tape into the machine housing through one discharge port, passing it between the second, third, and fourth guide wheels, and then extending it out through the other discharge port. The tape is positioned such that the section between the second and third guide wheels is at the same angle as the corresponding square tube. The positive and negative terminals are then connected to the circuit. A positive voltage is applied to the positive plate and multiple discharge pins through the positive terminal block and multiple conductive posts, causing all discharge pins to receive a high voltage equal to the positive potential of the power supply. Because the radius of curvature at the tip of the discharge needle is extremely small, a significant electric field distortion effect is generated under high voltage, leading to a sharp increase in the electric field strength near the tip. When the voltage between the needle tip and the negative electrode exceeds the air breakdown threshold, the strong electric field accelerates free electrons in the air to collide with gas molecules, initiating collisional ionization. The electron avalanche multiplication forms the initial ionization channel, and the gas molecules are ionized into positive ions, electrons, and excited-state particles. This process releases photons that excite the neighboring gas to further ionize, instantly opening the ionization channel between the needle tip and the negative electrode, generating a visible electric arc plasma. During the duration of the arc... Positive ions migrate towards the negative electrode plate, while electrons and negative ions migrate towards the positive electrode tip, forming a bidirectional ion flow. Then, a drive motor is activated, rotating the first horizontal axis. This, in turn, drives the connecting column in a circular motion via a rotating arm. The connecting column, through another rotating arm, drives the second horizontal axis to rotate. The connecting column, in conjunction with the sliding plate and U-shaped plate, moves the crossbeam back and forth. The crossbeam, through multiple insulating plates, moves multiple discharge needles back and forth, thus generating electric arcs and ion flows at different locations. Simultaneously, the first and second horizontal axes drive the active bevel gear to rotate, and through its interaction with the corresponding… The meshing of the driven bevel gear drives the shaft and fan blades to rotate, thereby generating a downward ion wind that blows towards the tape. If the tape carries a positive static charge, the negative ions in the airflow actively adsorb onto it, neutralizing the positive charge. If the tape carries a negative static charge, the positive ions migrate to the surface to complete the neutralization. If the static polarity of the tape is unknown or floating, the positive and negative ions cover it simultaneously, achieving bidirectional charge balance and removing static electricity from the tape. After the surface charge of the tape returns to zero, it loses its Coulomb force adsorption capacity for charged and polarized dust particles in the air, preventing dust adhesion. At the same time, the wind blows the dust particles off the surface of the tape. 2. In this invention, a dust removal and purification device for tape production is described. By starting the air pump, the air in the dust collection frame is extracted, allowing the air in the two suction pipes to enter the dust collection frame through the bend pipe. This creates a negative pressure at the end of the square tube, achieving dust adsorption. The section of the tape between the second and third guide wheels has the same inclination angle as the corresponding square tube, facilitating the instantaneous entry of dust blown off the tape into the square tube. The dust then enters the dust collection frame through the suction pipe and the bend pipe, where it is filtered and collected by the dust filter screen, thus achieving dust removal from the tape surface. The speed of the drive motor and the voltage applied to the positive terminal can be adjusted according to the dust condition of the tape. Increasing the speed of the drive motor can simultaneously improve the uniformity of the generated wind force and electric arc distribution, thereby ensuring the dust removal effect under different conditions. 3. In this invention, the dust removal equipment for tape production further removes residual dust from the tape surface by using dust-adhesive rollers, and drives the rotating shaft and rotating frame to rotate by starting a rotating motor, which in turn drives multiple dust-adhesive rollers to perform circumferential motion, thereby achieving further dust removal and purification. 4. In this invention, a dust removal and purification device for tape production filters dust from the air entering the machine housing through a filter screen, thereby preventing dust from entering the machine housing and adhering to the tape surface. As dust accumulates on the filter screen, the downward thrust of the wind on the filter screen increases. When the thrust exceeds the weight of the counterweight plate, the filter screen pulls the counterweight plate upward through a flexible belt. When the counterweight plate presses the touch button, it controls the drive motor to stop rotating and then pushes the L-shaped plate backward, so that the L-shaped plate aligns with the notch, thereby releasing the fixation of the fixed plate. Then, the filter frame is moved upward to achieve disassembly and cleaning. 5. In this invention, the purification and dust removal equipment for tape production utilizes a bidirectional ion flow generated by plasma discharge to cover the tape surface, effectively neutralizing the static electricity carried by the tape and eliminating the adsorption of dust particles by static electricity. Simultaneously, the generated ion wind assists in blowing away dust particles that have already adhered or detached due to static electricity loss. Combined with a specially designed negative pressure suction structure and a suction port tilted to match the tape's movement path, it can efficiently capture and collect the blown-off dust. The equipment also features a dust-adhesive roller assembly to assist in removing residual dust, further improving cleanliness. Furthermore, its air intake filter mechanism has an intelligent blockage warning function, automatically stopping the machine when dust accumulation on the filter affects performance. It also features a simple locking mechanism for quick disassembly and cleaning, thus achieving efficient, dynamic, and low-maintenance static electricity elimination and deep dust removal in the tape production process.

[0025] In this embodiment, the tape is inserted into the housing 1 through one of the discharge ports, passes between the second guide wheel 10, the third guide wheel 11, and the fourth guide wheel 12, and then extends out from the other discharge port. The tape is positioned such that the section between the second guide wheel 10 and the third guide wheel 11 is at the same angle as the corresponding square tube 204. Then, the positive terminal 507 and the negative terminal 504 are connected to the circuit. The positive voltage is applied to the positive plate 508 and multiple discharge needles 509 through the positive terminal plate 506 and multiple conductive posts 505, causing all discharge needles 509 to receive a high voltage equal to the positive potential of the power supply. Due to the discharge needles... The tip of the 509 electrode has an extremely small radius of curvature, resulting in a significant electric field distortion effect under high voltage. This leads to a sharp increase in the electric field strength near the tip. When the voltage between the tip and the negative electrode 502 exceeds the air breakdown threshold, the strong electric field accelerates free electrons in the air, causing collisional ionization. The avalanche-like multiplication of electrons forms an initial ionization channel, ionizing gas molecules into positive ions, electrons, and excited-state particles. This process releases photons that excite neighboring gas for further ionization, instantly opening the ionization channel between the tip and the negative electrode 502, generating a visible electric arc plasma. During the arc's duration, positive ions migrate towards the negative electrode 502, while electrons and negative ions migrate towards the negative electrode 502. Ions migrate towards the positive electrode tip, forming a bidirectional ion flow. Then, the drive motor 411 is activated, rotating the first horizontal shaft 408. This, in turn, drives the connecting column 410 in a circular motion via the rotating arm 409. The connecting column 410, via another rotating arm 409, drives the second horizontal shaft 407 to rotate. The connecting column 410, in conjunction with the sliding plate 513 and the U-shaped plate 512, drives the crossbeam 511 to move back and forth. The crossbeam, through multiple insulating plates 510, drives multiple discharge needles 509 to move back and forth, thereby generating an electric arc and ion flow at different positions. Simultaneously, the first horizontal shaft 408 and the second horizontal shaft 407 drive the active bevel gear 4... 06 rotates and drives the rotating shaft 403 and fan blade 404 to rotate through meshing with the corresponding driven bevel gear 405, thereby generating a downward ion wind that blows towards the tape. If the tape is positively charged, the negative ions in the airflow actively adsorb onto it and neutralize the positive charge. If the tape is negatively charged, the positive ions migrate to the surface to complete the neutralization. If the static polarity of the tape is unknown or floating, the positive and negative ions cover it simultaneously to achieve bidirectional charge balance and remove static electricity from the tape. After the surface charge of the tape is reduced to zero, it loses its Coulomb force adsorption ability for charged and polarized dust particles in the air, thus preventing dust adhesion. At the same time, the wind blows the dust particles off the surface of the tape. By activating the air pump 207, air is extracted from the dust collection frame 201, allowing air from the two suction pipes 203 to enter the dust collection frame 201 through the bend 202. This creates negative pressure at the end of the square tube 204, achieving dust adsorption. The section of the tape between the second guide wheel 10 and the third guide wheel 11 is at the same angle as the corresponding square tube 204, facilitating the instantaneous entry of dust blown off the tape into the square tube 204. The dust then enters the dust collection frame 201 through the suction pipes 203 and the bend 202, where it is filtered and collected by the dust filter 208, thus achieving dust removal from the tape surface. The speed of the drive motor 411 and the voltage applied to the positive terminal 507 can be adjusted according to the dust condition of the tape. Increasing the speed of the drive motor 411 can simultaneously improve the uniformity of the generated wind force and electric arc distribution, thereby ensuring dust removal effectiveness under different conditions. The dust residue on the tape surface is further adhered and removed by the dust-adhesive roller 305. The rotating shaft 403 and the rotating frame 304 are rotated by starting the rotating motor 302, which in turn drives the multiple dust-adhesive rollers 305 to perform circumferential motion, thereby achieving further dust removal and purification. The filter screen 602 filters dust from the air entering the housing 1, preventing dust from adhering to the tape surface. As dust accumulates on the filter screen 602, the downward thrust of the wind on the filter screen 602 increases. When the thrust exceeds the weight of the counterweight plate 701, the filter screen 602 pulls the counterweight plate 701 upward via the flexible belt 705. When the counterweight plate 701 presses the touch button 708, it controls the drive motor 411 to stop rotating and then pushes the L-shaped plate 802 backward, aligning the L-shaped plate 802 with the notch 70201, thereby releasing the fixation of the fixing plate 702. Then, the filter frame 601 is moved upward to achieve disassembly and cleaning.
