Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper-plastic separation technology, specifically a vertical paper-plastic separator. Background Technology
[0002] A paper-plastic separator is a device used to separate the paper and film in coated paper. Common types include horizontal and vertical paper-plastic separators, with the vertical type typically being smaller and more convenient to use. Our company discovered during the process of using a vertical paper-plastic separator to separate the film and paper that the properties of the film and paper are different. After the slit coated paper is poured into the vertical paper-plastic separator, the separator achieves separation through friction between friction blades and a friction perforated plate.
[0003] However, it was found that the separation time was relatively long each time. This was partly because the slit coated paper inside the vertical paper-plastic separator was relatively loose and did not easily settle down and be rubbed; and partly because after a period of use, the small holes of the friction plate were easily blocked by the broken membrane and paper, which affected the friction effect and resulted in low overall separation efficiency. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a vertical paper-plastic separator to solve the problem of low paper-plastic separation efficiency in existing vertical paper-plastic separators.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A vertical paper-plastic separator includes a fixed base, on which a separator cylinder and a drive motor are fixedly mounted. A friction perforated plate is horizontally fixed near the bottom of the inner wall of the separator cylinder. A drive shaft is vertically mounted on the fixed base. The upper end of the drive shaft passes through the separator cylinder and the friction perforated plate and is connected to friction blades located on the upper surface of the friction perforated plate inside the separator cylinder. The drive shaft and the drive motor are connected via a transmission mechanism. The friction perforated plate isolates a cavity at the bottom of the separator cylinder's inner cavity. Multiple sets of blower pipes are equidistantly connected to the circumferential sidewalls of the separator cylinder corresponding to the cavity. A solenoid valve is installed near the outlet end of each blower pipe. The inlet end of each blower pipe is connected to a distribution box mounted on the fixed base. An industrial blower with its outlet end connected to the distribution box is also mounted on the fixed base.
[0007] Preferably, the transmission mechanism includes pulleys fixedly mounted on the drive shaft and the output shaft of the drive motor, and a transmission belt installed between the two sets of pulleys.
[0008] Preferably, the height of the cavity does not exceed 10 cm.
[0009] Preferably, the bottom of the inner wall of the separation cylinder is provided with a flow guiding ridge, which is arc-shaped and distributed in a ring array.
[0010] Preferably, the height of the guide ridge is at least half the height of the cavity.
[0011] Preferably, a discharge hopper is also provided on the side wall of the separation cylinder, and a cover plate is movably hinged to the discharge end of the discharge hopper.
[0012] Preferably, a connecting frame is fixedly connected to the cover plate, and an electric telescopic rod is installed between the connecting frame and the separation cylinder.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention elevates the friction perforated plate and friction blades in the separation cylinder. During the friction separation process of the rotating separation blades, an industrial blower intermittently blows air to different positions below the friction perforated plate while the solenoid valve is intermittently on and off. This not only prevents the friction perforated plate from being blocked, but also promotes the continuous change of position of the slit coated paper, thereby promoting friction separation, improving separation efficiency, and shortening separation time. This solves the problem of low paper-plastic separation efficiency in existing vertical paper-plastic separators. Attached Figure Description

[0020] 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.
[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a vertical paper-plastic separator, including a fixed base 1, a separator 2 and a drive motor 3 fixedly installed on the fixed base 1, a discharge hopper 15 is also provided on the side wall of the separator 2, a cover plate 16 is movably hinged to the discharge end of the discharge hopper 15, a connecting frame 17 is fixedly connected to the cover plate 16, and an electric telescopic rod 18 is installed between the connecting frame 17 and the separator 2;
[0022] A friction perforated plate 4 is horizontally fixed on the inner wall of the separator 2 near the bottom. A drive shaft 5 is vertically installed on the fixed base 1. The upper end of the drive shaft 5 passes through the separator 2 and the friction perforated plate 4 and is connected to the friction blade 6 located on the upper surface of the friction perforated plate 4 inside the separator 2.
[0023] The drive shaft 5 and the drive motor 3 are connected by a transmission mechanism 7. The transmission mechanism 7 includes pulleys 12 fixedly installed on the output shafts of the drive shaft 5 and the drive motor 3, and a transmission belt 13 installed between the two sets of pulleys 12.
[0024] The friction orifice plate 4 isolates a cavity 8 at the bottom of the inner cavity of the separation cylinder 2. The height of the cavity 8 does not exceed 10 cm. The bottom of the inner wall of the separation cylinder 2 is provided with a flow guiding ridge 14. The flow guiding ridge 14 is arc-shaped and distributed in a ring array. The height of the flow guiding ridge 14 is at least half the height of the cavity 8.
[0025] Multiple sets of blower pipes 19 are equidistantly connected on the circumferential side wall of the cavity 8 corresponding to the separator 2. A solenoid valve 9 is installed near the air outlet of the blower pipe 19. The air inlet of the blower pipe 19 is connected to the diversion box 10 installed on the fixed base 1. An industrial blower 11 with its air outlet connected to the diversion box 10 is also installed on the fixed base 1.
[0026] Working principle:
[0027] The slit or pre-crushed coated paper is poured into the separation cylinder 2. The drive motor 3 drives the friction blades 6 to rotate through the transmission mechanism 7 and the drive shaft 5. The rotating friction blades 6 rub against the coated paper with the fixed friction perforated plate 4, thereby promoting the separation of the film and paper. During the friction separation, several solenoid valves 9 can be set to be synchronously and intermittently turned on and off, or they can be set to be turned on and off alternately. This allows the blower and blower pipe 19 to intermittently blow air to different positions below the friction perforated plate 4, which not only blows the crushed paper and film in the cavity 8 upward into the separation cylinder 2, but also prevents the small holes of the friction perforated plate 4 from being blocked. It also promotes the continuous change of position of the coated paper, promotes friction separation, improves separation efficiency, and shortens separation time.
