Description

Technical Field

[0001] This utility model relates to the field of antibacterial and antifungal masterbatch screening mechanism. Background Technology

[0002] Thermoplastic polyurethane (TPU) resin is a type of elastomeric polymer material containing a large number of urethane groups in its molecular chain. It combines the processing performance of plastics with the physical and mechanical properties of rubber. It can be processed using extrusion, injection molding, calendering, spinning, blown film, and other techniques, and its products have a wide range of applications. However, because thermoplastic polyurethane itself does not possess antibacterial and antifungal properties, TPU products are highly susceptible to the growth and reproduction of harmful microorganisms under suitable temperature and humidity conditions. Most antibacterial and antifungal functional rubber and plastic materials are produced by directly adding antibacterial and antifungal agents or antibacterial and antifungal masterbatches. The antibacterial and antifungal masterbatch method has advantages over the direct addition method in terms of dispersion effect, antibacterial effect, and process optimization. Antibacterial and antifungal masterbatch is a concentrate in which antibacterial and antifungal additives are uniformly dispersed in a carrier resin. It has advantages such as flexible application, easy storage, and the ability to promote more uniform dispersion of antibacterial and antifungal additives in the plastic substrate.

[0003] However, different particle sizes of masterbatch are used in different scenarios during screening. Traditional screening methods are inconvenient for classifying masterbatch of different particle sizes, and usually require multiple sievings using different filters. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an antibacterial and antifungal masterbatch screening mechanism, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an antibacterial and antifungal masterbatch screening mechanism, including a screening chamber, a sieve plate slot is provided on the inner side wall of the screening chamber, a filter screen plate slot is arrayed above the sieve plate slot on the inner side wall of the screening chamber, a filter screen plate is installed inside the filter screen plate slot, an inclined sieve plate is provided inside the sieve plate slot, a discharge trough is arrayed on the upper surface of the inclined sieve plate between two adjacent filter screen plates, a baffle is provided inside the discharge trough, and an elastic rotating shaft is installed between the baffle and the inclined sieve plate.

[0006] As a further embodiment of this utility model: one end of the sieve plate slot is provided with a pull-out notch on the side surface of the screening chamber, and a material leakage inclined plate is installed below the inclined sieve plate inside the screening chamber.

[0007] As a further embodiment of this utility model: the end of the material discharge plate near the pull-out notch is provided with a material discharge notch inside the screening chamber, and a sampling cabinet plate is provided inside the material discharge notch. A movable shaft is installed between the sampling cabinet plate and the screening chamber.

[0008] As a further embodiment of this utility model: the filter plate is engaged with the filter plate slot, and the inclined sieve plate is engaged with the sieve plate slot.

[0009] As a further improvement of this utility model, the baffle is movably connected to the inclined sieve plate via the elastic rotating shaft.

[0010] As a further improvement of this utility model, the material leakage inclined plate is fixedly connected to the screening chamber.

[0011] As a further improvement of this utility model, the aperture of the holes in the arrayed filter plates is arranged in decreasing order.

[0012] As a further improvement of this utility model: the sampling cabinet plate is movably connected to the screening chamber via the movable shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When a downward force is applied to the baffle at the corresponding position of the cavity, the baffle will rotate using the elastic rotating shaft and the inclined screening plate. The masterbatch will fall into the position above the leakage inclined plate. Then, by rotating the sampling cabinet plate with the movable shaft and the screening chamber, the masterbatch above will roll down from the end of the leakage inclined plate for easy collection.

[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 Figure 1-4 As shown, this embodiment provides an antibacterial and antifungal masterbatch screening mechanism, including a screening chamber 1. The screening chamber 1 has a sieve plate slot 102 on its inner wall. Above the sieve plate slot 102, a filter screen plate slot 101 is arrayed on the inner wall of the screening chamber 1. A filter screen plate 3 is installed inside the filter screen plate slot 101. The aperture of the holes in the arrayed filter screen plates 3 decreases progressively. The filter screen plates 3 are engaged with the filter screen plate slot 101. An inclined sieve plate 2 is engaged with the sieve plate slot 102. An inclined sieve plate 2 is arranged inside the sieve plate slot 102. A discharge trough 201 is arrayed on the upper surface of the inclined sieve plate 2 between two adjacent filter screen plates 3. A baffle 202 is arranged inside the discharge trough 201. An elastic rotating shaft 203 is installed between the baffle 202 and the inclined sieve plate 2. The baffle 202 is movably connected to the inclined sieve plate 2 via the elastic rotating shaft 203.

[0022] like Figure 2-3 As shown, in this embodiment, one end of the sieve plate slot 102 is provided with a pull-out notch 103 on the side surface of the screening chamber 1. Below the inclined sieve plate 2, a material leakage inclined plate 104 is installed inside the screening chamber 1. The material leakage inclined plate 104 is fixedly connected to the screening chamber 1. One end of the material leakage inclined plate 104 near the pull-out notch 103 is provided with a material discharge notch inside the screening chamber 1. A sampling cabinet plate 4 is provided inside the material discharge notch. A movable shaft 401 is installed between the sampling cabinet plate 4 and the screening chamber 1. The sampling cabinet plate 4 is movably connected to the screening chamber 1 through the movable shaft 401.

[0023] The working principle of this utility model is as follows: During use, the inclined sieve plate 2 is inserted into the sieve plate slot 102 from the pull-out notch 103. Then, multiple filter plates 3 are inserted into the filter plate slots 101 on the inner wall of the screening chamber 1. The insertion method involves decreasing apertures from one end of the pull-out notch 103 to the other. After the screened masterbatch is poured from the rightmost position onto the inclined sieve plate 2, the masterbatch inside is turned over by control, causing it to fall into the cavity formed between the two filter plates 3 and the inclined sieve plate 2. In the process, the masterbatch inside is turned over and operated in sequence. After the masterbatch of various particle sizes is air-screened into different cavities, when different masterbatches need to be collected, a downward force is applied to the baffle 202 at the corresponding position of the corresponding cavity. The baffle 202 will rotate using the elastic rotating shaft 203 and the inclined screening plate 2. The masterbatch will fall into the position above the leakage inclined plate 104. Then, by rotating the sampling cabinet plate 4 with the screening chamber 1 using the movable shaft 401, the masterbatch above will roll down from the end of the leakage inclined plate 104 for easy collection.
