However, when conveying cotton on an unwinding and cleaning carding machine, the cotton may pile up too high, which may cause the cotton to fall off the conveying device during the conveying process, affecting the conveying efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an energy-saving unwinding and impurity-removing carding machine, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving unwinding and impurity-removing carding machine, comprising: a support frame, on which the unwinding and carding machine body is fixedly mounted; a motor is fixedly mounted on the outer wall of the support frame; and a conveying device disposed on the inner wall of the support frame. The conveying device includes a turntable, a connecting rod, a sliding rod, a push plate, a baffle, a fixed frame, a sliding frame, a rotating plate, and a pressure plate. The rotation of the motor drives the turntable to rotate, which in turn drives the connecting rod to rotate, which in turn drives the sliding rod to rotate. The sliding rod reciprocates within a groove, and the sliding of the sliding rod drives the push plate to reciprocate. The reciprocating motion of the push plate flattens the excessively piled cotton. The turntable is fixedly mounted at the motor output end, and the connecting rod is rotatably mounted on the surface of the turntable. The sliding rod is fixedly mounted on the outer wall of the support frame. A sliding rod is fixedly installed on the side of the connecting rod near the support frame. A groove is formed on the surface of the support frame, and the sliding rod is slidably installed on the inner wall of the groove. A push plate is rotatably installed on the side of the sliding rod away from the connecting rod. A baffle is fixedly installed on the surface of the push plate and slidably installed on the inner wall of the support frame. A fixed frame is fixedly installed at the bottom of the baffle, and the sliding frame is slidably installed on the inner wall of the support frame. One end of a rotating plate is rotatably installed on the inner wall of the fixed frame, and the other end of the rotating plate is rotatably installed on the inner wall of the sliding frame. A pressure plate is fixedly installed on the surface of the sliding frame and slidably installed on the inner wall of the support frame. The reciprocating motion of the push plate causes the baffle to reciprocate, which in turn causes the fixed frame to reciprocate. The reciprocating motion of the fixed frame pulls the rotating plate to rotate, which in turn pulls the sliding frame downwards, and the downward movement of the sliding frame causes the pressure plate to move downwards.

[0007] According to the above technical solution, a first spring is provided between the baffle and the support frame, which drives the baffle to reset. A first torsion spring is provided between the rotating plate and the fixed frame, which drives the rotating plate to reset. A second torsion spring is provided between the rotating plate and the fixed frame, which drives the rotating plate to reset. A second spring is provided between the pressure plate and the inner wall of the support frame, which drives the pressure plate to reset.

[0008] According to the above technical solution, the support frame is equipped with a soil removal device, and a collection device is provided below the soil removal device. The soil removal device includes a connecting frame, a rotating shaft, a sieve plate, a fixed seat, and a rotating plate. The connecting frame moves downward by the downward movement of the pressure plate, which in turn moves the rotating plate downward. The downward movement of the rotating plate pushes the fixed seat downward, and the downward movement of the fixed seat causes the sieve plate to rotate downward. The connecting frame is fixedly installed on the surface of the pressure plate, the rotating shaft is rotatably installed on the inner wall of the support frame, the sieve plate is fixedly installed on the circumferential surface of the rotating shaft, the fixed seat is slidably installed on the top of the sieve plate, one end of the rotating plate is fixedly installed on the inner wall of the connecting frame, and the other end of the rotating plate is rotatably installed on the inner wall of the fixed seat.

[0009] According to the above technical solution, a fixing plate is fixedly installed on the top of the screen plate, a baffle plate is rotatably installed on the inner wall of the fixing plate, and a short plate is fixedly installed on the inner wall of the support frame. When the baffle plate rotates upward, it will contact the short plate, and the baffle plate will rotate downward under the obstruction of the short plate.

[0010] According to the above technical solution, a No. 3 torsion spring is provided between the rotating shaft and the support frame, and the rotating shaft is reset by the No. 3 torsion spring. A No. 3 spring is provided between the fixed seat and the sieve plate, and the fixed seat is reset by the No. 3 spring.

[0011] According to the above technical solution, a No. 4 torsion spring is provided between the fixed plate and the baffle plate. The No. 4 torsion spring drives the baffle plate to reset, and the short plate contacts the surface of the baffle plate.

[0012] According to the above technical solution, the collection device includes a push rod, a pulley, a sliding frame, a filter screen, and a collection box. The push rod rotates downward by rotating the sieve plate, which in turn rotates the pulley downward. The pulley then pushes the sliding frame downward, which in turn moves the filter screen downward. The push rod is fixedly installed at the bottom of the sieve plate, the pulley is rotatably installed on the inner wall of the push rod, the sliding frame is slidably installed on the inner wall of the support frame, the filter screen is disposed on the inner wall of the sliding frame, and the collection box is fixedly installed on the inner wall of the support frame.

[0013] According to the above technical solution, a square rod is fixedly installed at the bottom of the sliding frame, a sliding plate is slidably installed at the bottom of the inner wall of the collection box, a short rod is fixedly installed between the sliding plates, and a pushing block is fixedly installed at the top of the sliding plate. When the sliding frame moves downward, it drives the square rod to move downward. When the square rod moves downward, it pushes the pushing block to move away from the square rod. When the pushing block moves away from the square rod, it drives the sliding plate to move away from the square rod.

[0014] According to the above technical solution, the pulley is set above the sliding frame, and the sliding frame is pushed downward by the pulley. A No. 4 spring is set between the sliding frame and the support frame, and the sliding frame is reset by the No. 4 spring.

[0015] According to the above technical solution, the square rod is set above the push block, and a No. 5 spring is set between the collection box and the sliding plate, which drives the sliding plate to reset.

[0016] This invention provides an energy-saving unwinding and impurity-removing carding machine. It has the following beneficial effects: (1) In this invention, the sliding rod rotates and reciprocates in the chute. The sliding rod slides and drives the push plate to reciprocate. The reciprocating motion of the push plate flattens the cotton that is piled up too high, preventing the cotton from falling off the conveying device during the conveying process and affecting the conveying efficiency. At the same time, the pressure plate moves downward to press the cotton. The pressed cotton is more stable during the conveying process and is not easily affected by the external environment, ensuring the integrity of the raw materials in the transportation or transmission system and reducing losses. During the process of passing through the cotton, the rotating shaft and the screen plate can separate the impurities on the cotton, thereby achieving the effect of removing impurities from the cotton.

[0017] (2) In this invention, the downward movement of the connecting frame will drive the rotating plate to move downward, the downward movement of the rotating plate will push the fixed seat to move downward, and the downward movement of the fixed seat will drive the screen plate to rotate downward. The upward and downward rotation of the screen plate will shake off the soil or particles adhering to the cotton, preventing impurities from adhering to the inside of the cotton and affecting the impurity removal effect of the cotton, thus further improving the impurity removal effect of the cotton. At the same time, the upward rotation of the baffle plate will contact the short plate, and the baffle plate will rotate downward under the obstruction of the short plate. The intermittent opening of the baffle plate will allow the cotton to enter the unwinding carding machine body, so that the cotton stays on the screen plate for a longer time, thereby improving the impurity removal effect.

[0018] (3) In this invention, the pulley rotates downward to push the sliding frame to move downward, and the sliding frame moves downward to drive the filter screen to move downward. By moving the filter screen up and down, the impurities and cotton on the filter screen can be effectively separated, improving the impurity removal effect. At the same time, the cotton on the filter screen can be recycled to improve the conveying efficiency. Meanwhile, the sliding plate moves away from the square rod to push the impurities that fall into the collection box to flatten them, preventing the impurities from accumulating too high on one side of the collection box and affecting the collection effect of the collection box.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 One embodiment of the present invention is: an energy-saving unwinding and impurity-removing carding machine, comprising: a support frame 1, an unwinding and carding machine body 2 fixedly mounted on the surface of the support frame 1, a motor 3 fixedly mounted on the outer wall of the support frame 1, and a conveyor belt 4 drivenly mounted on the surface of the motor 3; a conveying device, disposed on the inner wall of the support frame 1, the conveying device including a turntable 5, a connecting rod 6, a sliding rod 7, a push plate 8, a baffle 9, a fixed frame 10, a sliding frame 11, a rotating plate 12, and a pressure plate 13, to prevent cotton from accumulating too high, causing cotton to fall off the conveying device during the conveying process, affecting the conveying efficiency; the turntable 5 is fixedly mounted on the output end of the motor 3; the connecting rod 6 is rotatably mounted on the surface of the turntable 5; the sliding rod 7 is fixedly mounted on the side of the connecting rod 6 near the support frame 1; and the surface of the support frame 1 is open. A chute is provided, with a slide rod 7 slidably installed on the inner wall of the chute, a push plate 8 rotatably installed on the side of the slide rod 7 away from the connecting rod 6, a baffle 9 fixedly installed on the surface of the push plate 8 and slidably installed on the inner wall of the support frame 1, a fixed frame 10 fixedly installed on the bottom of the baffle 9, a sliding frame 11 slidably installed on the inner wall of the support frame 1, one end of a rotating plate 12 rotatably installed on the inner wall of the fixed frame 10, and the other end of the rotating plate 12 rotatably installed on the inner wall of the sliding frame 11, and a pressure plate 13 fixedly installed on the surface of the sliding frame 11 and slidably installed on the inner wall of the support frame 1. The cotton is pressed by the downward movement of the pressure plate 13. The pressed cotton is more stable during the conveying process and is less affected by the external environment, ensuring the integrity of the raw materials in the transportation or transmission system and reducing losses.

[0023] A first spring is installed between the baffle 9 and the support frame 1, which drives the baffle 9 to reset. A first torsion spring is installed between the rotating plate 12 and the fixed frame 10, which drives the rotating plate 12 to reset. A second torsion spring is installed between the rotating plate 12 and the fixed frame 10, which drives the rotating plate 12 to reset. A second spring is installed between the pressure plate 13 and the inner wall of the support frame 1, which drives the pressure plate 13 to reset.

[0024] In this embodiment, during operation: the motor 3 drives the conveyor belt 4 to transport the cotton, causing the cotton to be unwound and combed within the cotton carding machine body 2. Simultaneously, the motor 3 drives the turntable 5 to rotate, which in turn drives the connecting rod 6 to rotate. The connecting rod 6 then drives the sliding rod 7 to rotate, reciprocating within the chute. This movement of the sliding rod 7 drives the pusher plate 8 to reciprocate, leveling any excessively piled cotton and preventing it from falling off the conveyor during transport. To improve conveying efficiency, the reciprocating motion of the push plate 8 drives the reciprocating motion of the baffle 9, which in turn drives the reciprocating motion of the fixed frame 10. The reciprocating motion of the fixed frame 10 pulls the rotating plate 12 to rotate, which in turn pulls the sliding frame 11 to move downward. The downward movement of the sliding frame 11 drives the pressure plate 13 to move downward. The downward movement of the pressure plate 13 presses the cotton, making the cotton more stable during the conveying process and less susceptible to external environmental influences. This ensures the integrity of the raw materials in the transportation or transmission system and reduces losses.

[0025] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, a soil removal device for treating soil is provided on the support frame 1, and a collection device is provided below the soil removal device. The soil removal device includes a connecting frame 141, a rotating shaft 142, a sieve plate 143, a fixed seat 144, and a rotating plate 145. The connecting frame 141 is fixedly installed on the surface of the pressure plate 13, the rotating shaft 142 is rotatably installed on the inner wall of the support frame 1, the sieve plate 143 is fixedly installed on the circumferential surface of the rotating shaft 142, the fixed seat 144 is slidably installed on the top of the sieve plate 143, one end of the rotating plate 145 is fixedly installed on the inner wall of the connecting frame 141, and the other end of the rotating plate 145 is rotatably installed on the inner wall of the fixed seat 144. By rotating the sieve plate 143 up and down, the soil or particles adhering to the cotton are shaken off, preventing impurities from adhering to the inside of the cotton and affecting the soil removal effect of the cotton.

[0026] A fixed plate 146 is fixedly installed on the top of the screen plate 143. A baffle plate 147 is rotatably installed on the inner wall of the fixed plate 146. A short plate 148 is fixedly installed on the inner wall of the support frame 1. The cotton enters the unwinding carding machine body 2 by intermittently opening the baffle plate 147, so that the cotton stays on the screen plate 143 for a longer time and improves the impurity removal effect.

[0027] A No. 3 torsion spring is provided between the rotating shaft 142 and the support frame 1. The No. 3 torsion spring drives the rotating shaft 142 to reset. A No. 3 spring is provided between the fixed seat 144 and the sieve plate 143. The No. 3 spring drives the fixed seat 144 to reset.

[0028] A No. 4 torsion spring is provided between the fixed plate 146 and the baffle plate 147. The baffle plate 147 is reset by the No. 4 torsion spring, and the short plate 148 contacts the surface of the baffle plate 147.

[0029] The collection device includes a push rod 151, a pulley 152, a sliding frame 153, a filter screen 154, and a collection box 155. The push rod 151 is fixedly installed at the bottom of the sieve plate 143, the pulley 152 is rotatably installed on the inner wall of the push rod 151, the sliding frame 153 is slidably installed on the inner wall of the support frame 1, the filter screen 154 is set on the inner wall of the sliding frame 153, and the collection box 155 is fixedly installed on the inner wall of the support frame 1. By moving the filter screen 154 up and down, impurities and cotton on the filter screen 154 can be effectively separated, improving the impurity removal effect. At the same time, the cotton on the filter screen 154 can be recycled, improving the conveying efficiency.

[0030] A square rod 156 is fixedly installed at the bottom of the sliding frame 153. A sliding plate 157 is slidably installed at the bottom of the inner wall of the collection box 155. A short rod 158 is fixedly installed between the sliding plates 157. A push block 159 is fixedly installed at the top of the sliding plate 157. When the sliding plate 157 moves away from the square rod 156, it will push the impurities that fall into the collection box 155 flat, preventing the impurities from accumulating too high on one side of the collection box 155 and affecting the collection effect of the collection box 155.

[0031] The pulley 152 is located above the sliding frame 153. The sliding frame 153 is pushed downward by the pulley 152. A No. 4 spring is provided between the sliding frame 153 and the support frame 1. The No. 4 spring drives the sliding frame 153 to reset.

[0032] A square rod 156 is positioned above the push block 159. A No. 5 spring is installed between the collection box 155 and the sliding plate 157, which drives the sliding plate 157 to reset.

[0033] In this embodiment, during operation: the downward movement of the pressure plate 13 causes the connecting frame 141 to move downwards. The downward movement of the connecting frame 141 causes the rotating plate 145 to move downwards. The downward movement of the rotating plate 145 pushes the fixed seat 144 downwards. The downward movement of the fixed seat 144 causes the screen plate 143 to rotate downwards. The up-and-down rotation of the screen plate 143 shakes off soil or particles adhering to the cotton, preventing impurities from adhering to the inside of the cotton and affecting the impurity removal effect. Simultaneously, the downward rotation of the screen plate 143 causes the fixed plate 146 to rotate downwards. The downward rotation of the fixed plate 146 causes the baffle plate 147 to rotate downwards, blocking... When the material plate 147 loses the obstruction of the short plate 148, it will reset under the action of the fourth torsion spring. The fourth torsion spring will cause the baffle plate 147 to rotate upward. The upward rotation of the baffle plate 147 will allow some cotton to enter the unwinding carding machine body 2 for processing. At the same time, the reset of the screen plate 143 will drive the fixed plate 146 and the baffle plate 147 to reset. The upward rotation of the baffle plate 147 will contact the short plate 148. Under the obstruction of the short plate 148, the baffle plate 147 will rotate downward. By intermittently opening the baffle plate 147, cotton can enter the unwinding carding machine body 2, so that the cotton stays on the screen plate 143 for a longer time, improving the impurity removal effect.

[0034] The downward rotation of the sieve plate 143 drives the push rod 151 to rotate downwards. This downward rotation of the push rod 151 causes the pulley 152 to rotate downwards, which in turn pushes the sliding frame 153 downwards. The downward movement of the sliding frame 153 then moves the filter screen 154 downwards. This up-and-down movement of the filter screen 154 effectively separates impurities and cotton fibers, improving the impurity removal effect. Simultaneously, the cotton fibers on the filter screen 154 can be recovered, improving conveying efficiency. Meanwhile, impurities fall into the collection box 155. The downward movement of the sliding frame 153 causes the square rod 156 to move downward. The downward movement of the square rod 156 pushes the push block 159 to move away from the square rod 156. The movement of the push block 159 away from the square rod 156 causes the sliding plate 157 to move away from the square rod 156. The movement of the sliding plate 157 away from the square rod 156 will flatten the impurities that have fallen into the collection box 155, preventing the impurities from accumulating too high on one side of the collection box 155 and affecting the collection effect of the collection box 155.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
