Description

Technical Field

[0001] This invention relates to the field of cotton stacking technology, and more specifically, to a cotton loose-fleck conveying stacker. Background Technology

[0002] Loose cotton is a loose fibrous material that has not been ginned and is characterized by high bulkiness, low density, easy fiber entanglement, poor flowability, easy dispersion, and easy moisture absorption. Existing loose cotton conveying and stacking equipment has many shortcomings in practical applications, which restricts the efficiency and stacking quality.

[0003] First, when loose cotton is conveyed to the hopper, the fibers easily become entangled, forming bridging blockages and causing interruptions in the feeding process. This requires frequent manual intervention to break the bridging, which is not only labor-intensive but also results in poor conveying continuity and low efficiency. Second, loose cotton is fluffy and easily disperses, and cotton fibers can easily escape from equipment gaps during conveying, leading to significant material loss, severe dust pollution in the workshop, and a harsh working environment. Third, existing equipment has poor feeding stability, with inconsistent cotton feed amounts. After stacking, the cotton stacks are loose, scattered, uneven in density, and inconsistent in height, making subsequent compaction difficult and ineffective, affecting the neatness of the cotton stacks. In addition, traditional equipment is mostly single-station stacking, and stacking, compaction, and unloading cannot be carried out simultaneously, resulting in poor process coordination, low automation, low overall operating efficiency, and high labor costs. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cotton loosening conveyor and stacker, which aims to solve the problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a cotton loosening conveyor and stacker, including a base, on which a conveying and stacking assembly is provided; The conveying and stacking assembly includes a conveying frame mounted on a base. A conveyor belt is installed inside the conveying frame. Several guide arc plates for gathering and pushing loose cotton are fixedly connected at equal intervals on the outer surface of the conveyor belt. A hopper is fixedly connected to one end of the conveying frame. The hopper has a feed hole that communicates with the inside of the conveying frame on the side facing the conveying frame. The multiple guide arc plates are rotated and circulated, pushing the cotton into the hopper. At the same time, the cotton is pressed and shaped by the inclined surface of the guide arc plates. A turntable is provided on one side of the top of the base. Several rubber columns are fixedly connected at equal intervals along the circumference on the upper surface of the turntable. A stacking positioning cylinder for cotton stacking is fixedly connected to the top of each rubber column. The rotation of the turntable drives each rubber column and stacking positioning cylinder to move sequentially, so as to transfer each stacking positioning cylinder to the bottom of the hopper for cotton stacking operation.

[0006] Furthermore, the conveying and stacking assembly also includes an electric slide rail fixedly installed on one side of the top of the base. A hydraulic rod is fixedly connected to the slider of the electric slide rail, and a stacking and gathering cylinder is fixedly connected to the piston rod end of the hydraulic rod. The horizontal position of the hydraulic rod and the stacking and gathering cylinder is adjusted by the electric slide rail, and then the stacking and gathering cylinder is driven to move downward by the hydraulic rod, so that the stacking and gathering cylinder covers the outside of the corresponding rubber column, which is used to radially gather the falling cotton and accurately stack it on the stacking positioning cylinder.

[0007] Furthermore, the stacking and gathering cylinder has a feed inlet on the side facing the conveying frame. When the stacking and gathering cylinder moves downward until its bottom end presses against the bottom of the rubber column, the feed inlet is connected to the discharge outlet of the hopper, so that the cotton is conveyed through the feed inlet into the interior of the stacking and gathering cylinder and gathered on the stacking positioning cylinder for stacking.

[0008] Furthermore, an electric push rod is fixedly connected to the top of the stacking and gathering cylinder, and a pressure ring is fixedly connected to the piston rod end of the electric push rod. The pressure ring is coaxially arranged with the stacking positioning cylinder and is used to drive the pressure ring to move downward to axially compact the cotton stacked on the stacking positioning cylinder.

[0009] Furthermore, the turntable has several L-shaped ventilation holes evenly spaced along the circumference inside. The vertical cross-section of each L-shaped ventilation hole is L-shaped, and the upper opening of each L-shaped ventilation hole extends to the bottom center of the corresponding rubber column.

[0010] Furthermore, a filter plate is embedded at the top center of each rubber column. The filter plate covers the upper opening of the corresponding L-shaped vent hole, so that airflow is discharged through the filter plate and the L-shaped vent hole, so that when the stacking and gathering cylinder is covered on the rubber column, a negative pressure state is formed inside the stacking and gathering cylinder.

[0011] Furthermore, an air extraction arc hood is slidably connected to the outer side of the turntable, and an air pump is fixedly connected to one side of the air extraction arc hood. The air extraction arc hood is located directly below the hopper. When each L-shaped vent hole on the turntable rotates to the bottom of the hopper in sequence, the L-shaped vent hole at the bottom of the hopper is connected to the inner cavity of the air extraction arc hood, which is used to extract air and form negative pressure during stacking operations.

[0012] Furthermore, a support bracket is rotatably connected to the bottom of the turntable, and a first servo motor is fixedly installed at the bottom of the support bracket. The output shaft of the first servo motor is fixedly connected to the central shaft of the turntable and is used to drive the turntable to rotate intermittently.

[0013] Furthermore, a second servo motor is fixedly installed at one end of the base, and a feeding hopper is fixedly installed at the top of the housing of the second servo motor. The inner cavity of the feeding hopper is configured as a frustum-shaped guide cavity that is wider at the top and narrower at the bottom.

[0014] Furthermore, a rotating blade is provided in the guide cavity of the feeding hopper, and the output axis of the second servo motor extends upward into the guide cavity and is fixedly connected to the central axis of the rotating blade for driving the rotating blade to rotate. A guide port is provided on one side of the inner wall of the feeding hopper, and the guide port is connected to the feed end of the conveying frame for the rotating blade to rotate and evenly transport the cotton in the feeding hopper to the conveying frame for conveying by the conveyor belt.

[0015] The technical effects and advantages of this invention are as follows: 1. This invention utilizes a conveyor belt to drive a guide arc plate in a cyclical displacement, gradually pushing and pressing the cotton in the hopper, continuously cutting and breaking down the cotton fiber arches, achieving automatic arch breaking without manual intervention. This avoids interruptions in material feeding, significantly improving conveying continuity. Furthermore, the guide arc plate pushes and gathers the cotton, combined with negative pressure adsorption, ensuring the cotton tightly adheres to the feeding channel, preventing fibers from escaping through gaps. This not only greatly reduces loose cotton loss and improves material utilization, but also reduces workshop dust, improving the working environment, while further ensuring the stability of the conveying process and avoiding feeding fluctuations caused by scattering. 2. The present invention uses a guide arc plate with equal spacing to push and press the cotton into the stacking area at a uniform speed and in a quantitative manner, avoiding inconsistent feeding. The negative pressure adsorption quickly gathers the cotton, and the stacking positioning cylinder precisely limits its movement. The synergistic effect of stable feeding and precise gathering makes the cotton stack neat, dense, uniform in density, and consistent in height, solving the problem of scattered stacking and reducing the workload of subsequent compaction processes. 3. The pre-pressing of the guide arc plate in this invention initially compacts the cotton, achieving standard density without excessive compaction upon entering the stacking area. The electric push rod, in conjunction with the pressure ring, precisely compacts axially, saving labor and increasing efficiency. Compaction energy consumption is significantly reduced, compaction efficiency is improved, and the cotton stack compaction is uniform and stable, avoiding over- or under-compaction issues and further optimizing stacking quality. Combined with the rotary table rotation driving the intermittent displacement of multiple stacking positioning cylinders, the stacking, compaction, and unloading processes are synchronously connected, with each station operating independently. With the automatic feeding, conveying, and compaction processes linked together, the degree of automation is greatly improved, manual intervention is reduced, overall operating efficiency is significantly increased, and labor costs are reduced.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Example 1 This invention discloses a cotton fluff conveying and stacking machine, such as... Figure 1-2 As shown, the entire system includes a base 1, which is made of rectangular steel plate. Adjustable anchor bolts are installed at the four corners of the bottom to adjust the level of the equipment. A conveying and stacking assembly is installed on the base 1 to complete the automatic conveying, gathering, stacking, and compaction of cotton bolls.

[0027] like Figure 3As shown, the conveying and stacking assembly includes a conveying frame 2 fixedly mounted on a base 1. The conveying frame 2 is a long, narrow trough structure with an annular conveyor belt 3 inside. Several guide arc plates 4 are fixedly connected at equal intervals to the outer surface of the conveyor belt 3. The guide arc plates 4 are made of rubber, have an arc-shaped cross-section, and have an inclined surface on the side facing the conveying direction. A discharge hopper 5 is fixedly connected to one end of the conveying frame 2. The discharge hopper 5 has a funnel-shaped structure that is wider at the top and narrower at the bottom. A feed hole connected to the interior of the conveying frame 2 is opened on the side facing the conveying frame 2. The arc of the feed hole matches the movement trajectory of the guide arc plates 4, so that the conveyor belt 3 drives the guide arc plates 4 through the arc-shaped notch into the discharge hopper 5, circulating in and out of the discharge hopper with the annular conveyor belt, thus gradually pressing the cotton inside the hopper.

[0028] A second servo motor 20 is fixedly mounted on one end of the base 1, and a feeding hopper 21 is fixedly mounted on the top of the housing of the second servo motor 20. The inner cavity of the feeding hopper 21 is configured as a frustum-shaped flow guide cavity that is wider at the top and narrower at the bottom, and a rotating blade 22 is arranged inside the flow guide cavity. The output axis of the second servo motor 20 extends upward into the flow guide cavity and is fixedly connected to the central axis of the rotating blade 22. A guide port 23 is opened on one side of the inner wall of the feeding hopper 21, and the guide port 23 is connected to the feed end of the conveying frame 2.

[0029] like Figure 4-5 As shown, a turntable 6 is rotatably connected to one side of the top of the base 1 via a bearing. The turntable 6 is a circular steel plate structure. A support bracket is rotatably connected to the bottom of the turntable 6, and a first servo motor 19 is fixedly installed at the bottom of the support bracket. The output shaft of the first servo motor 19 is fixedly connected to the central axis of the turntable 6, and is used to drive the turntable 6 to rotate intermittently. Several rubber pillars 7 are fixedly connected at equal intervals along the circumferential direction on the upper surface of the turntable 6. A stacking positioning cylinder 8 is fixedly connected to the top of each rubber pillar 7. The stacking positioning cylinder 8 is a cylindrical structure used for center positioning of the cotton stack.

[0030] An electric slide rail 9 is fixedly installed on one side of the top of the base 1. A hydraulic rod 10 is fixedly connected to the slider of the electric slide rail 9, and a stacking and gathering cylinder 11 is fixedly connected to the piston rod end of the hydraulic rod 10. The stacking and gathering cylinder 11 is a cylindrical structure with an open bottom, and its inner diameter is slightly larger than the outer diameter of the rubber column 7. A feed inlet 14 is opened on the side of the stacking and gathering cylinder 11 facing the conveying frame 2, and the size of the feed inlet 14 matches the size of the discharge outlet of the hopper 5.

[0031] like Figure 6 As shown, an electric push rod 12 is fixedly connected to the top of the stacking and gathering cylinder 11. The piston rod of the electric push rod 12 extends downward into the interior of the stacking and gathering cylinder 11, and a pressure ring 13 is fixedly connected to its end. The pressure ring 13 is a circular ring structure, and its inner diameter is slightly larger than the outer diameter of the stacking positioning cylinder 8. The pressure ring 13 is coaxially arranged with the stacking positioning cylinder 8.

[0032] like Figure 7 As shown, the interior of the turntable 6 has several L-shaped ventilation holes 15 evenly spaced along the circumference. Each L-shaped ventilation hole 15 has an L-shaped vertical cross-section, with one end opening onto the upper surface of the turntable 6 and extending to the bottom center of the corresponding rubber column 7, and the other end opening onto the side surface of the turntable 6. A filter plate 18 is embedded at the bottom center of each rubber column 7 to prevent cotton fibers from entering the L-shaped ventilation holes 15 and causing blockage.

[0033] An air extraction arc shroud 17 is slidably connected to the outer side of the turntable 6. The air extraction arc shroud 17 has an arc-shaped groove structure, and its opening fits tightly against the outer surface of the turntable 6. An air pump 16 is fixedly connected to one side of the air extraction arc shroud 17, and the air inlet of the air pump 16 is connected to the inner cavity of the air extraction arc shroud 17. The air extraction arc shroud 17 is located directly below the hopper 5, and its arc length is slightly greater than the arc length between two adjacent L-shaped vent holes 15, ensuring that during the intermittent rotation of the turntable 6, there is always one L-shaped vent hole 15 connected to the air extraction arc shroud 17.

[0034] The specific working principle is as follows: First, the loose cotton fibers after ginning are poured into the feed hopper 21. Then, the second servo motor 20 is started, which drives the rotating blades 22 to rotate. During the rotation, the rotating blades 22 push the loose cotton fibers in the feed hopper 21 to the guide port 23, and then into the conveyor frame 2 through the guide port 23.

[0035] The loose cotton fibers entering the conveyor frame 2 fall onto the conveyor belt 3. Driven by a motor, the conveyor belt 3 circulates, causing the guide arc plates 4 on it to move synchronously. During its movement, the guide arc plates 4 gather and push the loose cotton fibers, while simultaneously using their inclined surfaces to initially press and organize them, preventing them from scattering during transport. When the loose cotton fibers are conveyed to the end of the conveyor frame 2, they enter the feed hopper 5 through the feed hole.

[0036] Because the fibers of loose cotton are intertwined, they tend to pile up during the feeding process, easily forming an "arch bridge" structure at the closing point, leading to feeding interruption. This is the most common fault in all loose cotton conveying equipment. However, the conveyor belt 3 drives the guide arc plate 4 to circulate and gradually push the cotton in the feeding hopper 5. Its arc-shaped leading edge continuously cuts and breaks down the cotton fiber arch bridges that have formed or are forming, ensuring continuous feeding without manual intervention.

[0037] When the cotton has high moisture content and the fibers are severely adhered, the inclined surface of the guide arc plate 4 will apply a downward component force to the cotton, forcibly pushing the cotton to the discharge port of the feed hopper 5, avoiding the phenomenon of "only storing material but not discharging it". The gradual pushing and pressing gradually increases the density and weight of the cotton in the feed hopper 5, so that the cotton pushed by the guide arc plate 4 has a certain degree of compactness. After entering the stacking and gathering cylinder 11, it will not immediately become loose and scattered, so that the negative pressure air extraction system can more efficiently adsorb the cotton around the stacking positioning cylinder 8. Furthermore, the guide arc plate 4 also acts as a "movable baffle" during the pushing process, sealing the gap between the hopper 5 and the conveying frame 2, preventing cotton fibers from drifting out of the gap, which reduces material waste and improves the working environment.

[0038] Simultaneously, the first servo motor 19 drives the turntable 6 to rotate intermittently, causing an empty stacking positioning cylinder 8 to rotate directly below the unloading hopper 5. Then, the electric slide rail 9 drives the hydraulic rod 10 and the stacking gathering cylinder 11 to move downwards, so that the stacking gathering cylinder 11 covers the outside of the corresponding rubber column 7 until the bottom end of the stacking gathering cylinder 11 presses against the root of the rubber column 7. At this time, the inlet 14 on the stacking gathering cylinder 11 is exactly aligned with and connected to the outlet of the unloading hopper 5.

[0039] The air pump 16 is started, and the air pump 16 draws air through the L-shaped vent 15 connected to the air extraction arc shroud 17. The airflow is drawn out through the filter plate 18, the L-shaped vent 15, and the air extraction arc shroud 17, creating a negative pressure state inside the stacking and gathering cylinder 11. Under the action of negative pressure, the loose cotton in the feed hopper 5 is quickly sucked into the stacking and gathering cylinder 11, and under the positioning action of the stacking positioning cylinder 8, it is evenly stacked around the stacking positioning cylinder 8.

[0040] Once the stack reaches a certain height, the electric push rod 12 drives the pressure ring 13 to move downwards, axially compacting the cotton stacked on the stacking positioning cylinder 8. After compaction, the electric push rod 12 drives the pressure ring 13 to reset, and then the hydraulic rod 10 drives the stacking gathering cylinder 11 to reset upwards. The first servo motor 19 then drives the turntable 6 to rotate one position, causing the next empty stacking positioning cylinder 8 to rotate directly below the unloading hopper 5, repeating the stacking and compaction process.

[0041] Once all the stacking positioning cylinders 8 on turntable 6 have completed the cotton stacking, the operator can remove the stacked cotton from the stacking positioning cylinders 8 for subsequent packaging operations.

[0042] 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.
