[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The utility model is further described below in conjunction with specific embodiments.

[0036] Example 1

[0037] like Figure 1 and Figure 2As shown, a new type of central bin cotton mixing machine for needle punched nonwoven fabric production in this embodiment includes a frame 1, and the top plate of the frame 1 is provided with a top plate 16, and an air fiber separator is installed on the top plate 16. The outlet of the air fiber separator is connected to the inside of the frame 1, which plays a role in removing impurities from the fibers, and can filter the air, short fibers and impurities in the fibers to improve the cleanliness of the fibers. As a further improvement of this embodiment, the air fiber separator in this embodiment includes an air fiber separator I8 and an air fiber separator II9 arranged on the top plate 16 of the frame 1. By setting multiple air fiber separators, the filtering efficiency of the fibers can be improved.

[0038] The frame 1 is provided with a conveying flat curtain inside to convey the fibers. Figure 1 As shown, the conveying flat curtain of the utility model comprises a first conveying flat curtain 2 and a second conveying flat curtain 3 arranged parallel to each other. Figure 3 As shown, the first conveying flat curtain 2 is driven and connected to the first flat curtain transmission 17, and the second conveying flat curtain 3 is driven and connected to the second flat curtain transmission 18; the first flat curtain transmission 17 and the second flat curtain transmission 18 are both connected to the electrical control system of the center bin cotton mixer. Through the above settings, the orderly conveying of cotton fibers can be automatically controlled.

[0039] The frame 1 is also provided with an inclined corner nail curtain 4, the cotton inlet of the corner nail curtain 4 corresponds to the cotton outlet of the conveying flat curtain, and a circular arc leak bottom 12 is provided between the cotton outlet of the conveying flat curtain and the cotton inlet of the corner nail curtain 4. When in use, the circular arc leak bottom 12 is a "dead corner" for cleaning the equipment, which is difficult to clean. At the same time, the corner nail curtain 4 is used to transport the fibers to the cotton balancing roller 5 and the cotton stripping roller 6 provided above the frame 1, and process them in turn, and finally discharge the cotton from the cotton outlet 7 provided directly below the cotton stripping roller 6. At the same time, the cotton stripping roller 6 is prone to fiber residue during long-term use, and the position of the cotton stripping roller 6 is also a "dead corner" for cleaning, which is also difficult to clean.

[0040] like Figure 2 As shown, in order to solve the cleaning problem, the central bin cotton mixer of the utility model firstly has an observation window II 11 on the side wall of the frame 1 and located at the cotton stripping roller 6, and secondly, a through hole is provided on the side wall of the frame 1 at the position of the arc leakage bottom 12 set below the corner nail curtain 4, and a baffle 13 is rotatably installed on the outer side of the through hole, and the through hole is convenient for cleaning the residual fibers at the arc leakage bottom 12. Through the above structural improvements, when the color or variety of fibers is changed in the central bin cotton mixer, it is convenient to clean the residual fibers on the surface of the cotton stripping roller 6 and the arc leakage bottom 12 of the corner nail curtain 4, which significantly reduces the labor intensity and cleaning efficiency of the operators.

[0041] Specifically, the baffle 13 is fixedly mounted on the side wall of the frame 1 by rotating bolts. The baffle 13 can be rotated relative to the fixing bolts of the arc drain bottom 12. When the baffle 13 is turned away, the arc drain bottom 12 can be completely exposed. At the same time, in the design, the area of ​​the baffle 13 in this embodiment should be slightly larger than the area of ​​the through hole. Figure 4 As shown, when cleaning is not required, the baffle 13 can completely cover the through hole without affecting the operation of the device. Figure 5 As shown, when it is necessary to clean the residual fibers inside the circular arc leak bottom 12, it is only necessary to rotate the baffle plate 13 to expose the through hole and the circular arc leak bottom, and the operator can use the tool to clean the residual fibers inside the circular arc leak bottom 12, saving the operator's labor time and increasing the output of nonwoven fabrics. After cleaning, the baffle plate 13 is turned back to close the through hole.

[0042] In addition, the cotton evenly distributing roller 5 and the cotton stripping roller 6 are respectively arranged on both sides of the output port of the corner nail curtain 4, and the cotton outlet 7 is arranged below the cotton stripping roller 6; the cotton evenly distributing roller 5 is drivingly connected to the cotton evenly distributing roller transmission 20, the cotton stripping roller 6 is drivingly connected to the cotton stripping roller transmission 21, and the corner nail curtain 4 is drivingly connected to the corner nail curtain transmission 19. The cotton evenly distributing roller transmission 20, the cotton stripping roller transmission 21 and the corner nail curtain transmission 19 are all connected to the electrical control system of the middle bin cotton mixing machine, so as to realize the automatic control and operation of the equipment.

[0043] In addition, it should be noted that in order to achieve safe operation and cleaning and maintenance of the equipment, Figure 5 and Figure 7 As shown, a sensor 24 is installed at the movable door 22 of the frame 1, and the sensor 24 is connected to the electrical control system of the center bin cotton mixer. When the movable door 22 is in the open state, the electrical control system controls the center bin cotton mixer to be in the shutdown state.

[0044] Specifically, Figure 3 and Figure 6-7 As shown, in this embodiment, the movable door 22 can be flipped and installed on the frame 1, and the two ends of the movable door 22 are locked with the frame 1 through the door lock 23. A sensor 24 is arranged above the movable door 22. The sensor 24 is used to detect the opening state of the movable door 22. When the operator opens the door lock 23 and the movable door 22 to enter the middle warehouse cotton mixer to clean the residual fiber, the sensor 24 detects that the movable door 22 is opened and transmits the signal to the electrical control system. Other operators are unable to operate the middle warehouse cotton mixer, which increases the safety of the operators and avoids personal safety accidents. When the movable door 22 is closed, that is, the sensor 24 detects that the movable door has been opened and closed, the operation of the middle warehouse cotton mixer can be operated normally.

[0045] The central bin cotton mixing machine of the utility model can reduce the labor intensity of operators, improve the working efficiency and output of non-woven machinery, increase the safety of operators, and improve economic benefits.

[0046] Example 2

[0047] The present embodiment is a new type of central bin mixing machine for needle punched nonwoven fabric production, and its main structure is basically the same as that of the embodiment 1, and the difference between the embodiment 1 and the embodiment 1 is as follows: Figure 1-3 It is shown that on the vertical side walls of the frame 1, and at the middle of the corner nail curtain 4, dust removal fans 14 are respectively provided on the side walls of the frame 1 on both sides. The dust removal fans 14 are connected to the electrical control system of the middle bin cotton mixer. The control system can control the operation of the dust removal fans 14. By setting the dust removal fans on the sides of the corner nail curtain 4, the air inside the corner nail curtain 4 is in a positive pressure state, which prevents fibers from entering the corner nail curtain 4. The entry of fiber impurities can be reduced from the source, thereby ensuring the cleanliness of the product to a certain extent, improving the product quality of non-woven fabrics, and also reducing the labor intensity of equipment cleaning.

[0048] In addition, if Figure 2 As shown, in order to facilitate the inspection and maintenance of the middle-bin cotton mixer of this embodiment, a ladder 15 is also provided on the vertical side wall of the frame 1, and the ladder 15 extends from the bottom of the frame 1 to the top plate 16 of the frame 1, which is convenient for equipment maintenance. Figure 1 and Figure 6 As shown, the side walls of the frame 1 at the position of the conveying flat curtain are provided with an observation window Ⅰ10, which is convenient for observing production and cleaning. Specifically, in this embodiment, two observation windows Ⅰ10 are provided, one of which corresponds to the first conveying flat curtain 2, and the other corresponds to the second conveying flat curtain 3. The length of the first conveying flat curtain 2 is greater than that of the second conveying flat curtain 3, and the second conveying flat curtain 3 is arranged close to the angle nail curtain 4 arranged obliquely. By setting the positions of the two observation windows Ⅰ10, it is also convenient to observe the internal situation of the entire middle warehouse cotton mixer equipment. When it is observed that the interior needs to be cleaned, an operator can be dispatched to clean it.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
