Description

Technical Field

[0001] The present application relates to the technical field of lint cleaning machines, and specifically discloses a lint feeding device of a lint cleaning machine. Background Art

[0002] Why is it necessary to clean lint? In the process of cotton processing, there will always be some defects such as broken seeds, cotton knots and ropes (cotton gin). To solve the above problems, it is not enough to reduce the output. How to improve the quality of lint without affecting the output of lint, lint cleaning is necessary. On the one hand, by removing most of the large particles of impurities in the lint (such as infertile seeds, broken seed shells, etc.) and loosening most of the live ropes in the lint, the appearance of the lint is greatly improved, and the ginning quality of the lint is improved; on the other hand, because the adhesion between impurities and lint is relatively small before compression into packages, cleaning them can obtain a higher cleaning efficiency. Moreover, lint cleaning can give full play to the processing potential of the sawtooth cotton gin;

[0003] The output of sawtooth cotton gin is often restricted by the properties of seed cotton and the quality of lint cotton ginning. Seed cotton drying and lint cotton cleaning are the key to solving the contradiction between ginning output and quality.

[0004] The current mainstream in the market: airflow lint cleaner, air pressure lint cleaner and sawtooth lint cleaner;

[0005] About the airflow lint cleaning machine: The core is that the impurities are heavy and have greater inertia. Because it is difficult to change the original direction of movement, they continue to move forward, are thrown out from the adjustable gap, and are output to the outside of the machine by the impurity removal spiral;

[0006] About the sawtooth lint cleaning machine: the cotton layer is combed by the sawtooth hooks on the cotton feeding roller and the cotton feeding plate. The hooked fibers rotate at high speed with the licker-in roller. Because the large impurities such as sterile seeds are heavy, they move to the surface of the licker-in roller under the action of inertial centrifugal force, and are suspended in the outer layer of the licker-in roller airflow circle. They are impacted and cut by the impurity removal knife, discharged along the surface of the knife, and fall into the impurity removal box. The fibers pulled by the licker-in roller hook are brushed into the lint channel by the brush and sent to the total cotton dust cage;

[0007] Regarding the above two types, their cotton feeding devices both use airflow blowing, and the function of the cotton feeding device is simply to transport lint, and the subsequent lint cleaning is completed by a lint cleaning machine, which puts a lot of pressure on the lint cleaning machine. For example, stubborn clumps of cotton will affect the effect of the subsequent lint cleaning machine. For this reason, the inventor proposes a cotton feeding device for a lint cleaning machine. Utility Model Content

[0008] The utility model aims to solve the problem that the cotton feeding device of the traditional lint cleaning machine does not have the function of initially loosening the lint, and then all the pressure of lint cleaning is given to the lint cleaning machine, which leads to poor cleaning effect of the lint cleaning machine.

[0009] In order to achieve the above object, the utility model provides the following basic solutions:

[0010] A cotton feeding device for a lint cleaning machine comprises an input pipe, a cotton feeding pipe connected to the input pipe, a blower detachably connected to the input pipe, a spreading pipe assembly connected to the input pipe, and an output pipe connected to the spreading pipe assembly and used for connecting to the lint cleaning machine;

[0011] The pull-out pipe assembly includes a plurality of reducers, a plurality of pipe corner joints connecting the reducers and a plurality of stabilizing pipes. The inner diameter of the reducers gradually decreases along the direction of the input pipe. A plurality of retaining rods are arranged in the pipe corner joints and a plurality of cutting plates are arranged in the stabilizing pipe.

[0012] The principles and effects of this basic solution are:

[0013] 1. Compared with the prior art, the present device has a simple structure and an ingenious design. The present cotton feeding device not only has the conveying function of the traditional cotton feeding device, but also has the function of initially pulling and loosening the lint, sharing the pressure of lint cleaning, which is beneficial to the subsequent cleaning effect of the lint cleaning. Furthermore, the present device solves the problem that the cotton feeding device of the traditional lint cleaning machine does not have the function of initially pulling and loosening the lint, and thus all the pressure of lint cleaning is given to the lint cleaning machine, which will cause the cleaning effect of the lint cleaning machine to deteriorate.

[0014] 2. Compared with the prior art, the device is provided with a dispersion pipe assembly and adopts a reducer. The inner diameter of the reducer gradually decreases along the direction of the input pipe. If the air volume remains unchanged, the pipe diameter becomes smaller and the wind speed becomes larger. The increase in wind speed is used to enhance the dispersion of the lint. After being squeezed, it enters the corner joint of the pipe, where the wind speed is the highest. The lint is initially dispersed by utilizing the characteristic of the highest wind speed, and then enters the stabilizing pipe. A number of cutting plates are provided in the stabilizing pipe, and the lint is cut by the cutting plates to achieve dispersion of the lint. This solves the problem that the cotton feeding device of the traditional lint cleaning machine does not have the function of initially dispersing the lint, and then all the pressure of lint cleaning is given to the lint cleaning machine, which leads to a poor cleaning effect of the lint cleaning machine.

[0015] Furthermore, the input pipe is vertically connected to the cotton feeding pipe and the cotton feeding pipe is arranged on a side close to the air blower.

[0016] Furthermore, there are at least four reducers and pipeline corner joints, two of which are vertically arranged and connected through a corner joint, and a stabilizing pipe is arranged between the remaining reducers, and both ends of the stabilizing pipe are respectively connected to the respective reducers.

[0017] Furthermore, the stabilizing tube includes a first tube and a second tube, the first tube and the second tube are welded, the height of the partition located in the first tube decreases from left to right, and the height of the partition located in the second tube increases from left to right.

[0018] Furthermore, the pipe corner joint is threadedly connected to the reducer, and the retaining rods in the pipe corner joint are sequentially arranged along the arc direction of the pipe corner joint and the distances to the arc positions of the pipe corner joint are sequentially increased.

[0019] Furthermore, the pipe corner joint is wrapped with sound-proof cotton, which is mineral wool.

[0020] Furthermore, it also includes a support frame, which is used to stabilize the input pipe, the cotton feeding pipe, the spreading pipe assembly and the output pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] The reference numerals in the drawings of the specification include: input pipe 1, cotton feeding pipe 2, reducer 3, pipe corner joint 4, output pipe 5, inner diameter 6, stopper rod 7, stabilizing pipe 8, cutting plate 9.

[0028] Implementation example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown:

[0029] A cotton feeding device for a lint cleaning machine, comprising an input pipe 1, a cotton feeding pipe 2 connected to the input pipe 1, a blower detachably connected to the input pipe 1, a spreading pipe assembly connected to the input pipe 1, and an output pipe 5 connected to the spreading pipe assembly and used for connecting to the lint cleaning machine;

[0030] like Figure 1 As shown, the input pipe 1 is vertically connected with the cotton feeding pipe 2 and the cotton feeding pipe 2 is arranged on the side close to the blower. The reason why the input pipe 1 and the cotton feeding pipe 2 need to be vertically connected is that when the lint enters, in order to ensure that the lint falls in order, the vertical connection is least hindered. The cotton feeding pipe 2 is arranged on the side close to the blower so that when the lint enters the input pipe 1, it can be affected by the blower at the first time, and the air volume of the blower is used to transport the lint.

[0031] The pull-out tube assembly includes a plurality of reducers 3, a plurality of pipe corner joints 4 connected to the reducers 3, and a plurality of stabilizing tubes 8. The inner diameter 6 of the reducer 3 gradually decreases along the direction of the input tube 1. A plurality of retaining rods 7 are arranged in the pipe corner joints 4, and a plurality of cutting plates 9 are arranged in the stabilizing tube 8.

[0032] like Figure 1 As shown: there are at least four reducers 3 and the pipeline corner joints 4, two of which are vertically arranged and connected through the pipeline corner joints 4, and a stabilizing tube 8 is arranged between the remaining reducers 3, and both ends of the stabilizing tube 8 are respectively connected to the respective reducers 3.

[0033] like Figure 4 As shown, the stabilizing tube 8 includes a first tube and a second tube, the first tube and the second tube are welded, the height of the partition located in the first tube decreases from left to right, and the height of the partition located in the second tube increases from left to right.

[0034] The pipe corner joint 4 is threadedly connected to the reducer 3, and the blocking rods 7 located in the pipe corner joint 4 are sequentially arranged along the arc direction of the pipe corner joint 4 and the distances to the arc positions of the pipe corner joint 4 are sequentially increased.

[0035] Regarding the blocking rod 7: Since the pipe corner joint 4 is where the air volume is the largest, the noise here is also the largest. The pipe corner joint 4 is wrapped with silent cotton, which is mineral wool, to reduce noise. Because the air volume is the largest here, the lint can be blown away. The purpose of setting the blocking rod 7 is to allow the lint to be impacted, so that the lint can be more dispersed under the impact;

[0036] After being further dispersed, the lint enters the reducer pipe 3 again, and the air volume gradually increases, and the lint is dispersed again.

[0037] Regarding the cutting board 9: the dispersed lint enters the stabilizing tube 8. Since the inner diameter 6 of the stabilizing tube 8 is the same, the wind speed is stable, and the lint in the stabilizing tube 8 is stably transported, which will be blocked by the cutting board 9. After being blocked by the cutting board 9, there will be a speed difference for the lint, because the speed of the lint part blocked by the cutting board 9 is lower. The lint is dispersed through this speed difference, and finally, Figure 1 The lint removal pipe assembly is provided, and is output from the output pipe 5, and finally enters the lint cleaning machine.

[0038] The device also includes a support frame, which is used to stabilize the input tube 1, the cotton feeding tube 2, the pulling tube assembly and the output tube 5. Since the wind speed increases, there is a certain shaking of each component. Therefore, the device is provided with a support frame to improve the stability of the device.

[0039] Specific implementation process:

[0040] Lint is put into cotton feeding tube 2, and the blower is started. Under the action of the blower, the lint begins to be transported. Under the action of the scattering tube assembly, the lint begins to disperse and is finally transported out from output tube 5. Since output tube 5 is connected to the input of a lint cleaning machine, the dispersed lint enters the lint cleaning machine, and the lint cleaning machine can clean the lint.

[0041] The device solves the problem that the cotton feeding device of the traditional lint cleaning machine does not have the function of initially loosening the lint, and then all the pressure of lint cleaning is given to the lint cleaning machine, which will lead to poor cleaning effect of the lint cleaning machine.

[0042] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
