Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a dust sticking mechanism that can be quickly switched for use. Background Art

[0002] In the field of optical protective films, there are various types of films. During processing, high requirements are placed on surface cleanliness and flawlessness. Manufacturers will use a dust sticking mechanism to perform dust sticking treatment on the surface. Generally, the dust sticking mechanism uses a rubber roller and a paper tube in combination. The impurities on the film surface are transferred to the paper tube by the rubber roller. However, the adhesiveness on the paper tube is limited. Therefore, the dust sticking paper on its surface needs to be torn off every once in a while to ensure the dust sticking effect. This makes it necessary to stop using the dust sticking mechanism every once in a while, replace the paper tube, and then start using it again.

[0003] When the traditional dust sticking mechanism switches between the used state and the unused state, it will cause changes in the material tension due to changes in the film running length inside the dust sticking mechanism, thereby causing oscillations in the motors before and after the traction film, affecting the film feeding and winding effects, and ultimately affecting the production efficiency and product qualification rate of the enterprise.

The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0040] As Figure 4 and Figure 5 shown, it is a schematic diagram of a dust sticking mechanism commonly used in the prior art to simultaneously remove dust and impurities on both sides of the thin film 700. Among them, Figure 4 is the diagram of the unused state of this mechanism, Figure 5 is the diagram of the state of this mechanism during use. When the upper dust sticking roller assembly A and the lower dust sticking roller assembly A switch between the unused state and the used state, the length of the thin film 700 between the upper dust sticking roller assembly A and the lower dust sticking roller assembly A will change. That is, during the used state, the film running length of the thin film 700 between the upper dust sticking roller assembly A and the lower dust sticking roller assembly A will become longer. Therefore, the tension of this section of the thin film 700 will suddenly increase, thus affecting the oscillation of the traction motor on the upper transition roller A 803 and the lower transition roller A 804, and ultimately affecting the feeding process and winding process of the thin film 700.

[0041] For this reason, as Figures 1 to 3 shown, the present utility model provides a dust sticking mechanism for quick switching use to solve the above problems. It includes two oppositely arranged mounting vertical plates 100 for connecting each component. Between the two mounting vertical plates 100, three support rods 101 are further connected in the horizontal direction.

The two are used in cooperation to simultaneously remove micro dust, fluff and small impurities on both sides of the film 700. When in use, the film 700 is fed from the upper dust sticking device and discharged from the lower dust sticking device. It is defined that the feeding direction of the film 700 is to the left and its discharging direction is to the right.

[0044] Both ends of the upper transition roller 201 are respectively connected to one end of a rotating connecting piece 402, and the other ends of the two rotating connecting pieces 402 are fixedly connected to the upper position of the central axis of the corresponding side of the mounting vertical plate 100, so that the upper transition roller 201 is rotatably connected to the mounting vertical plate 100.

[0050] When the driving ends of the two first driving devices 500 are simultaneously extended, the upper dust sticking rubber roller 203 and the upper dust sticking paper cylinder 202 are driven to move away from the upper transition roller 201 at the same time. When the driving ends of the two first driving devices 500 are simultaneously retracted, the upper dust sticking rubber roller 203 and the upper dust sticking paper cylinder 202 are driven to move closer to the upper transition roller 201 at the same time.

[0051] When the driving end of the second driving device 501 extends, the upper dust sticking paper cylinder 202 moves away from the surface of the upper dust sticking rubber roller 203. When the driving end of the second driving device 501 retracts, the upper dust sticking paper cylinder 202 moves closer to the surface of the upper dust sticking rubber roller 203 and can even come into contact with the surface of the upper dust sticking rubber roller 203.

[0052] The first driving device 500 and the second driving device 501 are both driving cylinders.

[0053] The lower dust sticking device is arranged at a lower position between the two installation vertical plates 100. The lower dust sticking device includes a lower transition roller 301, a lower dust sticking roller assembly and two first driving devices 500.

[0054] Similar to the upper transition roller 201, the lower transition roller 301 is rotatably connected to the two installation vertical plates through a rotating connection member 402 and is vertically arranged below the upper transition roller 201. On the side of the lower transition roller 301 away from the upper dust sticking assembly, that is, on the left side of the lower transition roller 301, a lower dust sticking device is arranged in parallel, and the two are in the same plane.

[0055] The lower dust sticking roller assembly includes a lower dust sticking paper cylinder 302, a lower dust sticking rubber roller 303, two lower bearing plates 401, two second driving devices 501 and two adapter seats 403. Among them, each lower bearing plate 401 has the same structure as the above-mentioned upper bearing plate 400.

[0056] As described above, the two ends of the lower dust sticking rubber roller 303 are respectively rotatably connected to the rotating through holes of the two lower bearing plates 401. The pushing parts of the two lower bearing plates 401 are respectively connected to the driving ends of a first driving device 500, and the fixed ends of the first driving device 500 are respectively connected to the corresponding installation vertical plates 100.

[0057] The two ends of the lower dust sticking paper cylinder 302 are respectively rotatably connected to the rotation grooves 4033 of the two adapter seats 403. The adapter vertical plates 4032 of each adapter seat 403 are respectively connected to the driving ends of a second driving device 501. The fixed ends of each second driving device 501 are connected to the panel parts on each lower bearing plate 400, and the lower dust sticking paper cylinder 302 is located on the side of the upper dust sticking rubber roller 303 away from the lower transition roller 301, that is, on the left side of the lower dust sticking rubber roller 303, and the lower dust sticking paper cylinder 302 and the lower dust sticking rubber roller 303 are parallel to each other in the same plane.

[0058] The functions of the first driving device 500 and the second driving device 501 here are the same as those in the upper dust sticking roller assembly, and will not be elaborated here.

[0059] In addition, in order to eliminate the static electricity on both sides of the film 700, an electrostatic elimination assembly is provided on the side of the upper transition roller 201 away from the upper dust sticking roller assembly, and an electrostatic elimination assembly is provided on the side of the lower transition roller 301 away from the lower dust sticking roller assembly. The electrostatic elimination assembly includes two electrostatic elimination rods 601.

[0060] The two electrostatic elimination rods 601 on one side of the upper transition roller 201 are arranged in a vertically staggered manner. One electrostatic elimination rod 601 close to the upper transition roller 201 is arranged at a lower position, and a gap for the film 700 to be dusted to pass through is left between the two; the two electrostatic elimination rods 601 on one side of the lower transition roller 301 are arranged in a vertically staggered manner. One electrostatic elimination rod 601 close to the lower transition roller 301 is arranged at a lower position, and a gap for the film 700 to be dusted to pass through is left between the two.

[0061] In actual use, the upper transition roller 201 and the lower transition roller 301 are respectively connected with traction power, which is used to drive the feeding, discharging and winding of the film 700 and the rotation of the upper dust sticking roller assembly and the lower dust sticking roller assembly. The film 700 passes through the gap between the two electrostatic elimination rods 601 at the upper end, enters between the upper transition roller 201 and the upper dust sticking rubber roller 203, passes between the lower transition roller 301 and the lower dust sticking rubber roller 303, and exits through the gap between the two electrostatic elimination rods 601 at the lower end.

[0062] The operation process of the present utility model is as follows:

[0063] S1. Start the traction mechanism. The film 700 is placed on the surfaces of the upper transition roller 201 and the lower transition roller 301, and is fed by the rotation of the upper transition roller 201 and discharged by the rotation of the lower transition roller 301.

[0064] S2. By respectively adjusting the second driving device 501 in the upper dust sticking device and the lower dust sticking device, the surface of the upper dust sticking paper cylinder 202 is abutted against the surface of the upper dust sticking rubber roller 203, and the surface of the lower dust sticking paper cylinder 302 is abutted against the surface of the lower dust sticking rubber roller 303.

[0065] S3. Meanwhile, start the first driving device 500 in both the upper dust sticking device and the lower dust sticking device, so that the upper dust sticking rubber roller 203 moves closer to the upper transition roller 201 until the upper dust sticking rubber roller 203 abuts against the surface of the film 700; make the lower dust sticking rubber roller 303 move closer to the lower transition roller 301 until the lower dust sticking rubber roller abuts against the surface of the film 700. Thus, as the film 700 is transported, after the upper dust sticking rubber roller 203 adsorbs the dust impurities on the front side of the film 700, it is immediately transferred to the surface of the upper dust sticking paper tube 202, and after the lower dust sticking rubber roller 303 adsorbs the dust impurities on the back side of the film 700, it is immediately transferred to the surface of the lower dust sticking paper tube 302.

[0066] S4. When it is necessary to replace the upper dust sticking paper tube 202 and the lower dust sticking paper tube 302, start their corresponding second driving devices, so that the upper dust sticking paper tube 202 can quickly move away from the upper dust sticking rubber roller 203, and the lower dust sticking paper tube 302 can quickly move away from the surface of the lower dust sticking rubber roller 303, thereby realizing the quick switching of the upper dust sticking paper tube 202 and the lower dust sticking paper tube 302.

[0067] As Figure 6 shown, it is a schematic diagram of the unused state of the present utility model. As Figure 7 shown, it is a schematic diagram of the use state of the present utility model. It can be seen from the figure that when the present utility model is switched between the unused state and the use state, the length of the film 700 located between the upper dust sticking roller assembly and the lower dust sticking roller assembly will not change at all, thus well solving the problems occurring in the above-mentioned prior art.

[0068] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
