Description

Technical Field

[0001] This utility model relates to the field of cotton ginning machine technology, specifically a small-sized crankshaftless roller cotton ginning machine. Background Technology

[0002] A cotton gin is a type of cotton processing machinery. It separates the lint from the seed cotton. Traditional cotton gins typically use a crankshaft-connecting rod mechanism to drive the pressure rollers. However, this crankshaft-connecting rod mechanism results in a larger gin size, making it inconvenient for small workshops, family farms, or experimental research.

[0003] Currently, existing small-scale crankshaftless roller ginning machines typically use a motor or transmission structure to drive the rollers to separate cotton. During use, the rollers need to be disassembled for maintenance or to change to different patterns. However, the rollers are located inside the ginning machine, making disassembly inconvenient. Furthermore, the rollers are plated or inlaid with alloys, which wear down over time, requiring replacement and wasting resources. Additionally, multiple rollers with different patterns are needed, which are heavy and difficult to store and transport, further contributing to resource waste. Utility Model Content

[0032] Please refer to Figure 2. Figure 4 The transmission gear set 8 consists of two gears. One side of one gear of the transmission gear set 8 is fixedly connected to the pulley of the transmission structure 6. The transmission structure 6 is connected to the outer shell 1 and consists of two pulleys, a transmission belt, and a servo motor.

[0033] Specifically, the pulley of the transmission structure 6 is connected to the connecting shaft 9. The servo motor of the transmission structure 6 has a groove for heat dissipation and connecting wires at the rear. The servo motor is fixed to the outside of the housing 1, and its output shaft is coaxially connected to one of the pulleys.

[0034] Please refer to Figure 1. Figure 2 , Figure 4 The fixing plate 3 and the baffle 7 are located on the two sides of the outer shell 1, and one side of the fixing plate 3 is rotatably connected to the connecting shaft 9.

[0035] Specifically, the fixing plate 3 and the baffle 7 cooperate with each other to support the support frame 14.

[0036] Please see Figure 3 A storage box 16 is provided at the lower part of the outer shell 1, and the storage box 16 is located at the lower part of the embossed sleeve 12.

[0037] Specifically, the upper part of the storage box 16 is equipped with a mesh plate to block cotton fibers.

[0038] Please refer to Figure 6. A limiting rod 18 is fixedly connected to one side of the connecting ring 20. One end of the limiting rod 18 is inserted into the interior of the connecting roller 13. The limiting rods 18 are distributed in a ring array.

[0041] Specifically, the upper and lower parts of the support block 15 are respectively provided with arc grooves, the lower part of the fixing block 4 is provided with an arc groove, the arc grooves of the support block 15 and the fixing block 4 are matched with the connecting shaft 9, the upper part of the fixing block 4 is fixedly connected to the support frame 14 by bolts, the upper part of the support frame 14 is provided with a sliding groove, and the support block (15) and the fixing block (4) are slidably connected to the sliding groove by a slider.

[0042] In use, cotton is added through the feed hopper 2 and gradually moved to the middle of the rollers. The rollers rotate, ginning the cotton and extruding the cotton seeds, which fall into the storage box 16 for storage. A baffle plate is installed at the top of the storage box 16 to effectively prevent the cotton from falling. The ginned cotton is discharged through the discharge port 5. When replacing the rollers, the fixing plate 3 is removed, and the support frame 14 is pulled out by removing the fixing plate 3 from one side. The connecting shaft 9 of the rollers is then separated from the transmission gear set 8. The support frame 14, connecting shaft 9, and transmission gear set 8 are connected... The device allows for the separate installation of the embossing structure. After replacing the rolls, the support frame 14 is pushed into the outer casing 1, where the support frame 14 is restricted by the interior of the casing 1. The baffle 7 blocks one side of the support frame 14, and the fixing plate 3 is fixed with bolts, blocking the other side of the support frame 14. Through the coordinated arrangement of the baffle 7, the outer casing 1, and the fixing plate 3, the support frame 14 can be fixed during use, thus facilitating the removal of the embossing structure for convenient replacement of the rolls and achieving the purpose of convenient roll disassembly.

[0043] After prolonged use, the embossed sleeve 12 needs to be replaced with a different pattern or replaced due to wear. Pull the insert rod 19 to both sides to separate the end of the insert rod 19 from the connecting shaft 9, thereby pulling the connecting ring 20 outwards and separating it from the connecting shaft 9. This allows the embossed sleeve 12 to be replaced. After replacement, the connecting ring 20 is returned to its original position. The connecting ring 20 blocks the embossed sleeve 12, and the limiting block 17 outside the connecting ring 20 connects with the limiting groove 10 of the embossed sleeve 12, thus limiting the embossed sleeve 12. This is achieved through the limiting rod 18, the limiting groove 10, and... The setting of the limiting block 17, connecting ring 20, and insert rod 19 has the effect of restricting the calendering sleeve 12. After pulling out the support frame 14, the bolts on the upper part of the support frame 14 are removed, and the support frame 14 is taken out, so that the upper connecting shaft 9 can be taken out. Then the support block 15 is taken out, and then the lower connecting shaft 9 is taken out, thereby separating the roll from the support frame 14. Through the cooperation of the support block 15 and the fixing block 4, the roll can be easily replaced during use, thus facilitating the replacement of the calendering sleeve 12 and achieving the purpose of using the roll for a longer period of time.
