Description

Technical Field

[0001] This utility model relates to the field of carding and textile technology, and in particular to a mechanism for adjusting the thickness of the cotton layer in the cotton box of a carding machine. Background Technology

[0002] Adjusting the thickness of the cotton layer in the carding machine's cotton box is a crucial process for improving fiber combing quality and stabilizing production. If the cotton layer is too thin, it can easily cause fiber slippage, leading to over-combing and an increase in short fiber content. If the cotton layer is too thick, it can result in incomplete combing by the licker-in roller, leaving cotton bundles and increasing cotton knots.

[0003] Adjusting the thickness of the cotton layer in the cotton box is generally done by adjusting the cotton box pressure (K1 value) and optimizing the cotton feeding and delivery speed. The K1 value determines the standard pressure of the cotton box. Increasing K1 can improve the density of the cotton layer and reduce the cotton layer arching caused by the looseness of the fibers.

[0004] Adjusting the pressure of the cotton box is usually done by changing the air intake and exhaust flow rates. However, this method takes a while to complete the adjustment. Moreover, if a large adjustment is required, the air intake and exhaust flow rates will change abruptly, which may cause strong airflow disturbances and make it impossible for the cotton fibers inside to remain stable.

[0005] In addition, since the cotton feeding and delivery openings of the cotton box are usually in a normally open state, external air can easily enter the cotton box through the cotton feeding and delivery openings, affecting the cotton box pressure and making it difficult to adjust the cotton box pressure (K1 value). Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a cotton layer thickness adjustment mechanism for a carding machine, so as to solve the technical problems in the prior art that large-scale pressure adjustment can easily cause airflow disturbance and that the opening of the cotton box can hinder the pressure adjustment of the cotton box.

[0007] To achieve the above objectives, this utility model provides a cotton layer thickness adjustment mechanism for a carding machine, comprising a cotton box and a feeding channel installed on the cotton box, the adjustment mechanism further comprising:

[0008] An air supply pipe and an air extraction pipe are connected to the inner cavity of the cotton box, and both the air supply pipe and the air extraction pipe are equipped with flow control valves;

A piston plate is slidably connected inside the pressure regulating cylinder. A front electromagnet and a rear electromagnet are respectively provided on the front and rear sides of the piston plate.

[0010] Furthermore, the air supply pipe and the air extraction pipe are fixedly connected to the outer wall of the cotton box, and a filter screen is provided at the connection between the air supply pipe and the air extraction pipe and the inner cavity of the cotton box. A filter screen is also provided at the connection between the connecting empty box and the inner cavity of the cotton box.

[0011] Furthermore, the outer end of the air pressure regulating cylinder is fixedly connected to the fixed base plate, the fixed base plate is fixedly connected to the outer wall of the cotton box, the rear electromagnet is fixedly connected to the fixed base plate, and the front electromagnet is fixedly connected to the inner wall of the air pressure regulating cylinder through a fixing rod.

[0012] Furthermore, the lower opening of the feeding channel is located at the top of the cotton box, the top of the feeding channel is connected to the feeding pipe, and several sets of feeding rollers are arranged in parallel inside the feeding channel. The feeding rollers are rotatably connected inside the feeding channel and are used to feed raw cotton into the cotton box.

[0013] Furthermore, a feeding motor is mounted on the outside of the cotton box via a motor frame, and the feeding rollers are connected to the output shaft of the motor frame via a transmission component, with all groups of feeding rollers rotating synchronously.

[0014] Furthermore, a vibration motor is provided on the outer wall of the cotton box, and a vibration rod is provided inside the cotton box. The vibration rod is located below the upper opening of the cotton box and is connected to the vibration motor.

[0015] Furthermore, the cotton box is equipped with a feeding funnel with an inverted triangular cross-section, which divides the inner cavity of the cotton box into upper and lower layers. The cotton layer is located in the upper layer, and the connection ports of the air supply pipe and the air extraction pipe to the cotton box are also located in the upper layer.

[0016] Furthermore, a pair of feeding rollers are provided at the bottom of the feeding funnel for feeding raw cotton into the lower layer of the cotton box. Feeding motors are also provided on both sides of the feeding funnel, and the feeding rollers are connected to the output shaft of the feeding motors via belts.

[0017] Furthermore, the lower layer of the cotton box is provided with an inclined baffle and a triangular plate, and a conveyor belt is provided below the inclined baffle and the triangular plate. One end of the conveyor belt is located inside the cotton box, and the other end is located on the side of the carding machine. The lower end of the inclined baffle is slidably connected to the upper surface of the conveyor belt.

[0018] Furthermore, a pressure roller is provided above the conveyor belt. The pressure roller is movably connected to the lower end of the triangular plate through a pressure roller bracket.

The pressure regulating component includes a sliding piston plate. The movement of the piston plate changes the size of the space connecting the pressure regulating cylinder and the inner cavity of the cotton box, thus affecting the pressure of the cotton box. The sliding of the regulating piston plate is driven by two electromagnets, allowing for rapid response. Furthermore, the movement of the piston plate can be precisely controlled by changing the size of the electromagnets, making cotton box pressure regulation more convenient.

[0020] 2. A feeding channel is installed at the inlet of the cotton box. The feeding channel is designed as a long strip, and multiple sets of feeding rollers are installed within it to feed the raw cotton into the cotton box. This allows the raw cotton to fill the feeding channel, thereby maintaining a high degree of sealing at the inlet of the cotton box.

[0021] 3. One end of the conveyor belt is positioned inside the cotton box, and the outlet of the cotton box is relatively narrow. By installing a pressure roller at the outlet of the cotton box, the raw cotton is pressed against the conveyor belt, allowing it to pass smoothly through the outlet. While ensuring smooth feeding, the outlet of the cotton box is kept highly sealed, which in turn ensures a high degree of sealing within the cotton box cavity, making pressure adjustment of the cotton box more convenient and accurate.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0035] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0036] The first aspect of this utility model is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, adjusting the pressure of the cotton box is generally done by changing the air inlet and outlet flow rates. However, this method takes a considerable amount of time to complete the adjustment, and large-scale pressure adjustments can cause abrupt changes in the air inlet and outlet flow rates, potentially resulting in strong airflow disturbances that prevent the internal cotton fibers from remaining stable. Therefore, this solution, in addition to changing the air inlet and outlet flow rates of the air supply pipe 109 and the air extraction pipe 110, also includes a pressure regulating component on the cotton box 106.

[0037] Specifically, an air supply pipe 109 and an air extraction pipe 110 are fixedly connected to the outer wall of the cotton box 106. The air supply pipe 109 and the air extraction pipe 110 are connected to the inner cavity of the cotton box 106, and both the air supply pipe 109 and the air extraction pipe 110 are equipped with flow control valves.

[0038] The pressure regulating assembly includes a connecting empty box 122 and a pressure regulating cylinder 123. The connecting empty box 122 is fixedly connected to the outer wall of the cotton box 106 and communicates with the inner cavity of the cotton box 106. The pressure regulating cylinder 123 is fixedly connected to the side wall of the connecting empty box 122 and communicates with it. A piston plate 127 is slidably connected inside the pressure regulating cylinder 123. A front electromagnet 125 and a rear electromagnet 126 are respectively provided on the front and rear sides of the piston plate 127.

[0039] In addition, the outer end of the air pressure regulating cylinder 123 is fixedly connected to the fixed base plate 124, the fixed base plate 124 is fixedly connected to the outer wall of the cotton box 106, the rear electromagnet 126 is fixedly connected to the fixed base plate 124, and the front electromagnet 125 is fixedly connected to the inner wall of the air pressure regulating cylinder 123 through the fixing rod 128.

[0040] Preferably, the air supply pipe 109 and the air extraction pipe 110 are fixedly connected to the outer wall of the cotton box 106, and a filter screen 121 is provided at the connection between the air supply pipe 109 and the air extraction pipe 110 and the inner cavity of the cotton box 106. A filter screen 121 is also provided at the connection between the connecting empty box 122 and the inner cavity of the cotton box 106.

[0041] Flow control valves are installed on the gas supply pipe 109 and the gas extraction pipe 110 for main regulation, and an additional pressure regulating component is installed on the cotton box 106 for auxiliary regulation and to improve the regulation speed. The pressure regulating component includes a sliding piston plate 127. The movement of the piston plate 127 changes the size of the space connecting the air pressure regulating cylinder 123 and the inner cavity of the cotton box 106, thereby affecting the pressure of the cotton box 106. The sliding of the piston plate 127 is driven by two electromagnets, allowing for rapid response. Furthermore, the movement of the piston plate 127 can be precisely controlled by changing the size of the electromagnets, making pressure regulation of the cotton box 106 more convenient.

[0042] The second aspect of this utility model is as follows: Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, since the cotton feeding and conveying openings of the cotton box are generally in a normally open state, external air can easily enter the cotton box through these openings, affecting the cotton box pressure and making it difficult to adjust the cotton box pressure (K1 value). Therefore, in this embodiment, a feeding channel 101 is provided at the upper end of the cotton box 106. The lower opening of the feeding channel 101 is located at the top of the cotton box 106. The top of the feeding channel 101 is connected to the feeding pipe 102, and several sets of feeding rollers 105 are arranged in parallel inside the feeding channel 101. The feeding rollers 105 are rotatably connected inside the feeding channel 101 for feeding raw cotton into the cotton box 106.

[0043] A feeding motor 104 is mounted on the outside of the cotton box 106 via a motor frame 129. The feeding rollers 105 are connected to the output shaft of the motor frame 129 via a transmission component 103, and all sets of feeding rollers 105 rotate synchronously.

[0044] Preferably, a vibration motor 107 is provided on the outer wall of the cotton box 106, and a vibrating rod 108 is provided inside the cotton box 106. The vibrating rod 108 is located below the upper opening of the cotton box 106 and is connected to the vibration motor 107.

[0045] The feed channel 101 is designed as a long strip, and multiple sets of feed rollers 105 are installed within it to feed raw cotton into the cotton box 106. This allows the raw cotton to fill the feed channel 101, thereby ensuring that the inlet of the cotton box 106 remains highly sealed.

[0046] In addition, a feeding funnel 111 is provided inside the cotton box 106. The cross-section of the feeding funnel 111 is an inverted triangle, dividing the inner cavity of the cotton box 106 into upper and lower layers. The cotton layer is located in the upper layer, and the connection ports of the air conveying pipe 109 and the air extraction pipe 110 to the cotton box 106 are also located in the upper layer. A pair of feeding rollers 112 are provided at the bottom of the feeding funnel 111 for feeding raw cotton into the lower layer of the cotton box 106. Feeding motors 113 are also provided on both sides of the feeding funnel 111, and the feeding rollers 112 are connected to the output shaft of the feeding motors 113 via belts.

[0047] The lower layer of the cotton box 106 is provided with an inclined baffle 114 and a triangular plate 118. Below the inclined baffle 114 and the triangular plate 118, there is a conveyor belt 115. One end of the conveyor belt 115 is located inside the cotton box 106, and the other end is located on the side of the carding machine. The lower end of the inclined baffle 114 is slidably connected to the upper surface of the conveyor belt 115.

[0048] Above the conveyor belt 115 is a pressure roller 116, which is movably connected to the lower end of the triangular plate 118 via a pressure roller bracket 117. A spring 119 is also provided between the pressure roller bracket 117 and the triangular plate 118. Inside the conveyor belt 115 below the pressure roller 116 is a pad 120, which is fixedly connected to the inner wall of the cotton box 106 and slidably connected to the inner surface of the conveyor belt 115.

[0049] One end of the conveyor belt 115 is positioned inside the cotton box 106, and the outlet of the cotton box 106 is relatively narrow. A pressure roller 116 is installed at the outlet of the cotton box 106, pressing the raw cotton against the conveyor belt 115 to allow it to pass smoothly through the outlet of the cotton box 106. This ensures smooth feeding while maintaining a high degree of sealing at the outlet of the cotton box 106, thereby maintaining a high degree of sealing within the inner cavity of the cotton box 106, making pressure adjustment in the cotton box more convenient and accurate. Furthermore, a vibrating rod 108 and a discharge funnel 111 are installed inside the cotton box 106. The vibrating rod 108 loosens the falling raw cotton, while the discharge funnel 111 divides the inner cavity of the cotton box 106 into upper and lower layers, further ensuring the sealing of the upper layer of the cotton box 106, making pressure adjustment in the cotton box more convenient and accurate.

[0050] In summary, this invention provides flow control valves on the air supply pipe 109 and air extraction pipe 110 of the cotton box 106 for primary regulation, and additionally provides a pressure regulating component on the cotton box 106 for auxiliary regulation, thereby improving the regulation speed. The pressure regulating component includes a sliding piston plate 127. The movement of the piston plate 127 changes the size of the space connecting the air pressure regulating cylinder 123 and the inner cavity of the cotton box 106, thus affecting the pressure of the cotton box 106. The sliding of the piston plate 127 is driven by two electromagnets, allowing for rapid response. Furthermore, the movement of the piston plate 127 can be precisely controlled by changing the size of the electromagnets, making pressure regulation of the cotton box 106 more convenient.

[0051] A feeding channel 101 is provided at the inlet of the cotton box 106. The feeding channel 101 is elongated and multiple sets of feeding rollers 105 are installed within it to feed raw cotton into the cotton box 106. This allows the raw cotton to fill the feeding channel 101, thus maintaining a high degree of sealing at the inlet of the cotton box 106. One end of the feeding conveyor belt 115 is located inside the cotton box 106, and the outlet of the cotton box 106 is relatively narrow. A pressure roller 116 is installed at the outlet of the cotton box 106. The pressure roller 116 presses the raw cotton against the conveyor belt 115, allowing it to pass smoothly through the outlet of the cotton box 106. While ensuring smooth feeding, the outlet of the cotton box 106 is kept highly sealed, thereby maintaining a high degree of sealing within the inner cavity of the cotton box 106, making pressure adjustment of the cotton box more convenient and accurate. In addition, a vibrating rod 108 and a feeding funnel 111 are installed inside the cotton box 106. The vibrating rod 108 loosens the falling raw cotton, while the feeding funnel 111 divides the inner cavity of the cotton box 106 into upper and lower layers, further ensuring the sealing of the upper layer of the cotton box 106 where the cotton layer is located.
