Description

Technical Field

[0001] This invention relates to the field of cotton seed delinting machine technology, specifically to an automatic adjustment mechanism for the working box of a delinting machine. Background Technology

[0002] After cleaning, the cotton seeds are transported by a winch or by pneumatic conveyor into the seed storage box at the top of the delinting machine. A pair of automatically speed-adjustable feeding rollers feed the cotton seeds from the storage box evenly and continuously. The seeds pass through a seed-discharging plate to absorb impurities (iron media) and enter the working box. In the working box, the cotton seeds are propelled by a high-speed rotating seed-distributing roller and hooked by a high-speed rotating saw blade cylinder, forming cotton seed rolls. Utilizing the appropriate density and pressure of the cotton seed rolls, and the difference in linear speed between the rolls and the saw blade cylinder, the saw blade can hook or scrape the short cotton fibers from the cotton seeds, allowing... When the cotton lint hooked or scraped off by the saw blade passes the working point of the ribs, it separates from the cotton seed roll and moves in a circular motion with the saw blade. When it passes the impurity removal area, the impurities are too large and detach from the saw blade. The cotton lint is brushed off or sucked down by airflow and enters the lint collector through the pipe. After being cleaned by the cleaning machine, it is packaged. The cotton seeds that have been staying in the working box for a relatively long time have their surface lint reduced after several scrapings, which reduces the adhesion between the cotton seeds. They will slide down the ribs between the saw blades and enter the next stripping or the next process. This is the cotton seed delinting process.

[0003] In this process, the design parameters of the working chamber play a decisive role in the yield and quality of cotton linters. See Figure 1 This includes: the upper crossbeam and density board (number 4); the binding plate assembly (number 5); the seed-discharging roller (number 6); the strip-laying assembly (number 7); and the delinting saw blade (number 8). From traditional delinting technology, it is known that, under a certain saw cylinder speed and unit output, controlling the quality of cotton lint, besides the saw blade, working box parameters, and whether the brush or airflow effectively removes lint from the saw teeth, mainly relies on controlling the density of the working box. Older models achieved this by controlling the pressure of the density board and manually adjusting the binding plate. With increased output, the movable density board can no longer function properly, so all currently in service models have changed to a fixed design for the density board and binding plate. Workers can only sacrifice output to some extent to meet quality and residual lint requirements, because under the current process structure, the seed feed rate can never be constant, always with slight fluctuations. However, once the working parameters of the delinting machine are set, the seed discharge rate is basically constant. When the amount of seeds fed exceeds the amount of seeds discharged, two problems arise: first, the amount of broken seeds increases, and the quality of short fibers decreases; second, the seed-discharging roller motor is overloaded or burns out. The purpose of this invention is to solve this problem.

[0004] Publication (Announcement) No.: CN1060825C, Publication (Announcement) Date: 2001-01-17 A method and system for automatically controlling cotton lap density is proposed, which involves fixing a horizontal ruler with a sliding weight to the pressure plate of a delinting machine's working box, installing an angle sensor on the frame to detect the pressure plate's swing angle, and controlling the density controller of the speed-regulating motor, speed controller, reducer, and other components through changes in the pressure plate angle. The system is simple to operate, reliable in operation, and provides significant control effects, making it applicable to various models of delinting machines.

[0005] Publication (Announcement) No.: CN113122932A, Publication (Announcement) Date: 2021-07-16 discloses a high-yield and energy-saving cotton stripping machine, including a machine body. A saw cylinder and a brush cylinder are rotatably connected within the machine body. A working box is disposed within the machine body. A seed-removing roller shaft is rotatably connected within the working box. A visible seed storage box is connected above the working box. A feeder is fixedly connected to the upper part of the visible seed storage box. The feeder includes an adjustable feeding roller rotatably connected to the side of the visible seed storage box and an adjustable movable plate installed in the visible seed storage box and opposite to the adjustable feeding roller. The bristles on the outer periphery of the brush cylinder are tangent to the outer periphery of the saw cylinder. A saw blade with a thickness of 1.2mm and an outer diameter of 460mm is used. The bottom-opening working box is twice the size, allowing for greater and denser cotton seed storage, ensuring higher output. The cotton seed processing is entirely enclosed, generating no dust, eliminating the need for a dust removal unit in the workshop, saving energy and reducing costs.

[0006] The technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of the present invention. For more technical features, technical problems to be solved, and beneficial effects of the present invention, the above-disclosed technical documents do not provide any technical inspiration. Summary of the Invention

[0007] In view of the above-mentioned defects in the existing technology, the purpose of the present invention is to provide an automatic adjustment mechanism for the working box of a delinting machine, which uses a spring structure to automatically adjust the gravity component of the clamping plate and the front pressure of the cotton seed roll in a timely manner; at the same time, the elasticity of the internal spring can be adjusted to adapt to various working conditions.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An automatic adjustment mechanism for the working box of a deflashing machine includes a retaining plate installed in the working box of the deflashing machine.

[0010] It also includes a spring seat mechanism, one end of which is connected and fixed to the working box wall panel of the stripping machine working box, and the other end of which is connected and fixed to the retaining plate on the working box of the stripping machine.

[0011] The spring seat mechanism includes a spring seat, a bent plate, a compression spring, and a spring seat base;

[0012] The upper end of the compression spring is connected to the spring seat, and the lower end of the compression spring is connected to the bottom part of the spring seat. The bottom part of the spring seat is connected to the clamping plate.

[0013] The upper end of the bending plate is connected to a spring seat, and the lower end of the bending plate is connected to the working box wall panel.

[0014] The spring seat has an upper half-cylinder for the upper end of the compression spring to extend into, and the bottom part of the spring seat has a lower half-cylinder for the lower end of the compression spring to extend into.

[0015] The outer diameter of the lower half-cylinder is smaller than the inner diameter of the upper half-cylinder, meaning the lower half-cylinder extends into the upper half-cylinder, and the two together form a guiding mechanism.

[0016] The spring seat also has bolt holes for installing spring pressure adjusting bolts, and the inner end of the spring pressure adjusting bolts presses against the upper end of the compression spring through a pressure cap.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] A spring mechanism is added to the working box of an existing delinting machine. When the density of cotton seed rolls in the working box increases, the frontal pressure on the inner arc surface of the binding plate increases. When this frontal pressure exceeds the component of the combined weight of the binding plate, the binding plate will rotate outward around its hanging axis. At this time, the volume of the working box increases, the gap between the cotton seed comb and the sliver increases, the amount of seeds discharged increases, and the density of cotton seed rolls in the working box decreases until the binding plate returns to its original position under the action of the component of gravity. Different production quality requirements require different working densities of cotton seed rolls. When the component of gravity of the binding plate is greater than the frontal pressure of the cotton seed roll, the spring's function is to reduce the weight component of the binding plate; conversely, the spring's function is to increase the weight component of the binding plate. This invention uses a spring structure to automatically adjust the component of gravity of the binding plate and the frontal pressure of the cotton seed roll in a timely manner; at the same time, the elasticity of the internal spring can be adjusted to adapt to various working conditions.

Detailed Implementation

[0024] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1:

[0026] like Figures 1 to 4 As shown, the present invention provides an automatic adjustment mechanism for the working box of a stripping machine, including a retaining plate 5 provided in the working box assembly 21 of the stripping machine;

[0027] It also includes a spring seat mechanism, one end of which is connected and fixed to the working box wall panel 23 of the working box of the stripping machine, and the other end of which is connected and fixed to the retaining plate on the working box of the stripping machine.

[0028] The spring seat mechanism includes a spring seat 24, a bent plate 25, a compression spring 26, and a spring seat base 27;

[0029] The upper end of the compression spring is connected to the spring seat, and the lower end of the compression spring is connected to the bottom part of the spring seat. The bottom part of the spring seat is connected to the clamping plate.

[0030] The upper end of the bending plate is connected to a spring seat, and the lower end of the bending plate is connected to the working box wall panel.

[0031] The spring seat has an upper half-cylinder for the upper end of the compression spring to extend into, and the bottom part of the spring seat has a lower half-cylinder for the lower end of the compression spring to extend into.

[0032] The outer diameter of the lower half-cylinder is smaller than the inner diameter of the upper half-cylinder, meaning the lower half-cylinder extends into the upper half-cylinder, and the two together form a guiding mechanism.

[0033] The spring seat also has bolt holes for installing the spring pressure adjusting bolt 211, and the inner end of the spring pressure adjusting bolt presses the upper end of the compression spring through the pressure cap.

[0034] As the density of cottonseed rolls in the working box increases, the frontal pressure on the inner arc surface of the binding plate increases. When this frontal pressure exceeds the component of the combined weight of the binding plate, the binding plate will rotate outward around its hanging axis. At this time, the volume of the working box increases, and the gap between the cottonseed comb and the sliver increases, resulting in an increase in the amount of cottonseed discharged. Meanwhile, the density of cottonseed rolls in the working box decreases until the binding plate returns to its original position under the influence of gravity. Different production quality requirements necessitate different working densities of cottonseed rolls. When the component of gravity on the binding plate exceeds the frontal pressure of the cottonseed roll, the spring's function is to reduce the weight component of the binding plate; conversely, the spring's function is to increase the weight component of the binding plate. This invention uses a spring structure to automatically adjust the component of gravity on the binding plate and the frontal pressure of the cottonseed roll in a timely manner. Furthermore, the internal spring's elasticity can be adjusted to adapt to various working conditions.

The bottom part of the spring seat is connected to the wall panel of the working box. The upper end of the bending plate is connected to the spring seat, and the lower end of the bending plate is connected to the clamping plate.
