Description

Technical Field

[0001] This utility model relates to the technical field of roller ginning machines, specifically a double roller ginning device for textiles. Background Technology

[0002] A cotton gin is a type of cotton processing machinery that separates lint from raw cotton. It requires that the quality of the cotton fibers and the cotton seeds not be damaged during the ginning process. Common types include saw gins and roller gins. Roller gins utilize the surface of rollers with a high coefficient of friction to adhere to and move cotton fibers, thereby achieving separation from the cotton seeds. They have a simple structure, low manufacturing cost, are easy to operate and maintain, and are less likely to break cotton fibers. They are suitable for processing fine cotton, long-staple cotton, and seed cotton with poor maturity.

[0003] The existing roller ginning equipment lacks a sealing device during the ginning process, causing the cotton lint produced during ginning to fly everywhere, polluting the working environment. At the same time, operators are prone to inhaling the flying cotton lint into their nasal cavity, causing health harm. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example

[0029] Please see Figures 1 to 6The present invention provides a technical solution including a housing 1, a seed-removing assembly 2, and a pressure roller assembly 3. The seed-removing assembly 2 and the pressure roller assembly 3 are both disposed inside the housing 1. A feed inlet 101 is provided on the side wall of the housing 1. A cover 102 is rotatably installed on the inner side of the feed inlet 101. Connecting posts are provided on both sides of the top of the cover 102 and inserted into the inner walls of the feed inlet 101 on both sides. A guide plate is provided at the bottom of the feed inlet 101 on the inner side of the housing 1, extending to the right side of the first roller 202. A seed outlet 103 is provided on the lower side of the feed inlet 101 on the side wall of the housing 1. A movable plate 104 is slidably installed on the outer side of the seed outlet 103 on the side wall of the housing 1. A discharge outlet 105 is provided on the opposite side wall of the feed inlet 101 of the housing 1.

[0030] The deseeding assembly 2 also includes a fixed blade 201, a first roller 202, and a second roller 203. Two connecting screws 204 are rotatably mounted on the top of the fixed blade 201. Connecting shafts 205 are fixedly mounted on the inner sides of both the first roller 202 and the second roller 203. A drive motor 206 is fixedly connected to one end of the connecting shaft 205 on the first roller 202. Drive gears 207 are fixedly mounted on the outer sides of both connecting shafts 205. A connecting gear 208 meshes between the two drive gears 207.

[0031] The pressure roller assembly 3 includes a cotton removal knife 301, two rotating motors 302 and two pressing rollers 303. The cotton removal knife 301 and the pressing rollers 303 are rotatably mounted inside the machine housing 1. The two rotating motors 302 are fixedly mounted on the outside of the machine housing 1, and the output end of the rotating motor 302 is fixedly connected to one end of the pressing roller 303.

[0032] Specifically, by setting up a baffle 102, a movable plate 104, and a sealing block 107 to block the feed inlet 101, the seed outlet 103, and the air inlet 106, the amount of cotton lint that blows out of the feed inlet during cotton tying is reduced. During discharge, the cotton lint is compacted by the pressure roller assembly 3, so that the cotton lint is compact and well-shaped when it is discharged from the outlet, thereby reducing the amount of cotton lint that blows everywhere. At the same time, the compacted cotton lint is easy to collect quickly. Through the cooperation of the fixed blade 201 and the first roller 202, the cotton lint and cotton seeds are initially separated by the device. Then, the first roller 202 and the second roller 203 are driven to rotate by two drive gears 207 with different numbers of teeth, so that the two rollers rotate at different speeds, which enhances the pulling force on the fibers and performs secondary separation of the remaining cotton seeds to ensure that the cotton seeds are completely removed.

[0033] Please refer to Figure 1 to Figure 2 The top of the housing 1 has two threaded through holes. The inner surface of the threaded through holes is adapted to the outer threaded surface of the connecting screw 204, and the width of the fixed blade 201 is adapted to the inner width of the housing 1. The fixed blade 201 is slidably installed inside the housing 1 through the connecting screw 204.

[0034] Specifically, by rotating the connecting screw 204, the distance between the fixed blade 201 and the first roller 202 can be changed, thereby dynamically adjusting the position of the fixed blade 201 according to the size of the cotton seeds, balancing the separation efficiency and fiber integrity.

[0035] Please refer to Figure 3 to Figure 4 The two drive gears 207 have different numbers of teeth. The number of teeth of the drive gear 207 fixed on the connecting shaft 205 connected to the first roller 202 is less than the number of teeth of the drive gear 207 fixed on the connecting shaft 205 connected to the second roller 203.

[0036] A connecting through hole is provided on the side wall of the housing 1. A through connecting hole is provided at the center of the side end of the first roller 202 and the second roller 203. The inner diameter of the connecting through hole and the through connecting hole is adapted to the outer diameter of the connecting shaft 205. The drive gear 207 on the outside of the housing 1 is fixedly connected to the first roller 202 and the second roller 203 inside the housing 1 through the connecting shaft 205. The back side of the connecting gear 208 is provided with a positioning post connected to the side wall of the housing 1 to realize the positioning of the connecting gear 208.

[0037] Specifically, by using two drive gears 207 with different numbers of teeth and connecting shaft 205 to connect with two rollers, the two rollers rotate at different speeds, which enhances the pulling force on the cotton fibers and ensures that the cotton seeds are completely peeled off.

[0038] Please see Figure 5 The width of the cotton removal knife 301 is equal to the inner width of the machine housing 1. The cotton removal knife 301 is fixedly installed on the lower left side of the second rubber roller 203 inside the machine housing 1, and the two pressing rollers 303 are rotatably installed on the upper left side of the cotton removal knife 301 inside the machine housing 1.

[0039] Specifically, the cotton fibers adhering to the second roller 203 are separated by the action of the cotton removal knife 301, thereby compacting the cotton fibers by the pressure roller assembly 3.

[0040] Please refer to Figure 5 to Figure 6 The inner bottom surface of the housing 1 is an inclined surface. The height of the inner bottom surface of the housing 1 near the discharge port 105 is higher than the height of the end near the feed port 101. The bottom height of the cotton removal knife 301 is higher than the height of the inner bottom surface of the housing 1 at the same position on its longitudinal plane.

[0041] Specifically, by utilizing the inclined bottom surface, the cotton seeds falling on the inner bottom surface of the casing 1 will roll towards the seed outlet 103.

[0042] Please refer to Figure 5 to Figure 6A sliding groove is provided on the side wall of the housing 1. The width of the sliding groove is equal to the width of the movable plate 104, and the height of the sliding groove is greater than the height of the movable plate 104. The movable plate 104 is slidably installed in the sliding groove on the side wall of the housing 1. A positioning pin is inserted into the top of the movable plate 104. A positioning hole is provided on the top inner side of the sliding groove. The movable plate 104 can be fixed after being raised by the cooperation of the positioning pin and the positioning hole.

[0043] Specifically, by pulling the movable plate 104, the seed outlet 103 is opened, making it easier to discharge the cotton seeds inside the machine casing 1.

[0044] Please refer to Figure 4 to Figure 6 Multiple air inlets 106 are provided on the lower side of the discharge port 105 on the side wall of the housing 1. Each air inlet 106 has a sealing block 107 threadedly installed on its inner side. The bottom height of the air inlet 106 is equal to the top height of the bottom surface of the inner side of the housing 1 near the discharge port 105.

[0045] Specifically, the air inlet blows air into the inside of the casing 1, thereby blowing some residual cotton seeds and cotton lint toward the seed outlet 103 for discharge.

[0046] In use, cotton is fed into the machine housing 1 through the feed inlet 101. When feeding stops, the cover 102 falls down due to its own weight, blocking the feed inlet 101. The cotton inside the machine housing 1 comes into contact with the first roller 202 through the guide plate. When the roller rotates at high speed, its surface friction grabs the cotton fibers and drags the mixture of cotton fibers and cotton seeds toward the fixed knife 201. Through the cooperation of the fixed knife 201 and the first roller 202, the cotton fibers are continuously pulled through the gap by the roller, while the cotton seeds are intercepted and fall off by the fixed knife, achieving physical separation. Initial separation is achieved using the fixed knife 201 and the first roller 202. Then, because the number of teeth of the drive gear 207 connected to the connecting shaft 205 of the first roller 202 is less than the number of teeth of the drive gear 207 connected to the connecting shaft 205 of the second roller 203, the two rollers... Different rotation speeds enhance the pulling force on the fibers, ensuring complete removal of cotton seeds. The cotton removal knife 301 removes the cotton lint adhering to the second roller 203. The cotton lint then adheres to the pressing roller 303 of the pressure roller assembly 3. The motor 302 drives the pressing roller 303 to rotate, and the pressure roller assembly 3 compacts the cotton lint. The cotton lint is then discharged from the discharge port 18 on the inner left side of the machine housing 1. After the work is completed, the movable plate 104 is pulled up in the groove on the side wall of the machine housing 1. The movable plate 104 is fixed by the positioning pin and the positioning hole on the side wall, exposing the seed outlet 103 on the side wall of the machine housing 1, and discharging the cotton seeds inside the machine housing 1. For the cotton seeds and lint remaining on the bottom inner side of the machine housing 1, the air inlet 106 is opened to blow air into the machine housing 1, thereby discharging the remaining cotton lint and cotton seeds inside the machine housing 1.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
