Description

Technical Field

[0001] This utility model relates to the technical field of cotton processing equipment, and in particular to a pre-cleaning device for impurities in cotton purchasing. Background Technology

[0002] In the initial stages of cotton purchasing and processing, raw cotton typically contains various impurities such as cotton leaves, cotton seeds, and sand. These impurities not only affect the quality grade and price of the cotton but also damage subsequent textile processes. Therefore, specialized cleaning equipment is usually required to pre-clean the cotton before large-scale processing.

[0003] Currently, most cotton pre-cleaning devices on the market use the principle of mechanical drum separation. These devices are usually equipped with a rotating drum with filter holes and spikes. When cotton containing impurities enters the equipment, the rotating drum can break up the cotton clumps. By utilizing the difference in density and size between cotton fibers and impurities, smaller and heavier impurities are separated out through the filter holes on the drum surface, thereby achieving the purpose of preliminary cleaning.

[0004] However, because cotton is a highly fibrous material, cotton fibers easily become entangled or adhere to the surface of the drum during its high-speed rotation and tumbling. Simultaneously, impurities containing moisture also stick to it. Over time, these deposits gradually clog the filter pores on the drum surface, blocking the impurity separation channels.

[0005] Once the filter pores become heavily clogged, the separation efficiency of the device drops sharply, and a large amount of impurities cannot be effectively removed, remaining in the cotton and significantly reducing the pre-cleaning effect. To restore equipment performance, operators have to frequently stop the machine to manually clean the roller surface, which not only interrupts production continuity and reduces overall work efficiency, but also significantly increases the cost and labor intensity of manual maintenance. Therefore, this utility model proposes an impurity pre-cleaning device for cotton purchasing to address the shortcomings of the existing technology. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a cotton purchasing impurity pre-cleaning device, which aims to improve the problem that some existing cotton purchasing impurity pre-cleaning devices have low cleaning efficiency because the filter holes on the surface of the cleaning roller are easily blocked by cotton fibers and impurities during operation.

[0007] This utility model provides a pre-cleaning device for cotton purchasing, comprising a body, a shell, a first motor, a rotating rod, a connecting rod, and a roller; the device also includes an anti-clogging mechanism. The anti-clogging mechanism includes a mounting plate, a second motor, a threaded rod, and a brush plate. The mounting plate is fixedly connected to the inner wall of the shell, the second motor is fixedly connected to the mounting plate, and the threaded rod is fixedly connected to the drive end of the second motor, with the axis of the threaded rod parallel to the axis of the roller; the brush plate is slidably connected to the outside of the threaded rod, and the brush plate abuts against the outer surface of the roller, enabling the brush plate to reciprocate along the roller axis under the drive of the threaded rod while the roller rotates, continuously cleaning the roller surface.

[0008] Preferably, the roller has a cylindrical structure, filter holes are provided on the cylinder wall, and spikes are fixed in an array on its outer surface. The structure can effectively break up cotton clumps through the spikes and separate impurities from cotton through the filter holes.

[0009] Preferably, the device further includes a disassembly mechanism and auxiliary components. The disassembly mechanism includes a waste bin, which is movably connected inside the machine body and located below the roller, for receiving and collecting impurities separated by the roller.

[0010] Preferably, as a means of implementing the disassembly mechanism, the auxiliary components include a guide rail and a slider. The guide rail is fixedly connected to the inner bottom wall of the machine body, and the slider is fixedly connected to the bottom of the waste bin. The slider and the guide rail are slidably engaged, thereby allowing the waste bin to be conveniently slid into or out of the machine body in a drawer-like manner.

[0011] Preferably, to achieve locking of the waste bin, the disassembly mechanism further includes a chassis, a cylinder, and an upper locking pin. The chassis is fixedly connected to the back of the waste bin, the cylinder is fixedly connected to the top of the chassis, and the upper locking pin is fixedly connected to the top of the cylinder, forming a locking structure that is linked to the waste bin.

[0012] Preferably, in conjunction with the aforementioned locking structure, the disassembly mechanism further includes a round rod, a locking block, and a spring. The round rod is fixedly connected to a groove inside the machine body, the locking block is fixedly connected to the top of the round rod for locking the upper locking pin, and the spring is sleeved on the outside of the round rod to provide elastic potential energy for the locking block to automatically reset, ensuring the reliability of the locking.

[0013] Preferably, to unlock the waste bin, the disassembly mechanism further includes a movable column. The movable column is slidably connected to the cylinder and is linked to the waste bin. When the waste bin is pulled, the movable column acts on the locking block, causing it to overcome the spring force and release the upper locking column, thus achieving rapid unlocking.

[0014] Preferably, the auxiliary component further includes a feed plate. The feed plate is fixedly connected to the upper part of the machine body and is inclined. The inclined design utilizes gravity to guide the cotton to automatically slide into the cleaning area where the roller is located, simplifying the feeding operation.

[0015] Preferably, the auxiliary component further includes a door. The door is rotatably connected to the machine body via a hinge, and its function is to close the opening where the waste bin slides in or out, ensuring that the device forms a sealed space during operation to prevent dust and impurities from spilling out.

[0016] Preferably, the auxiliary component further includes a discharge port. The discharge port is located on the machine body and on the side of the roller away from the feed plate, facilitating the smooth discharge of clean cotton after cleaning under the conveying action of the roller.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem in the prior art where the filter holes on the surface of the roller are easily blocked by cotton fibers when the roller separates cotton impurities by setting an anti-clogging mechanism driven by a motor to drive the threaded rod and drive the brush plate to reciprocate along the roller axis. This results in low cleaning efficiency and inability to operate continuously. The invention achieves the technical effect of efficient and continuous automated cleaning by setting an anti-clogging mechanism driven by a motor to drive the threaded rod and drive the brush plate to reciprocate along the roller axis.

[0019] 2. This utility model solves the problem of cumbersome, time-consuming and labor-intensive disassembly and cleaning of the impurity collection box in the prior art by setting up a pull-out structure consisting of a waste bin, guide rail and slider, and a quick-release locking mechanism consisting of a chassis, cylinder, upper locking post, locking block, spring and moving post. It achieves the technical effect that the operator only needs to pull the waste bin to unlock and slide it out, and push it back after cleaning to automatically reset and lock it, which greatly improves the convenience of maintenance and work efficiency.

[0020] 3. This utility model solves the problem of dust and impurities easily scattering and polluting the working environment during cotton cleaning by setting an openable door on the machine body to close the disassembly and assembly opening of the waste bin, and sealing the working parts such as the roller with the outer shell. It achieves the technical effect of making the entire pre-cleaning process in a closed space, effectively preventing the leakage of pollutants, and ensuring the cleanliness of the operating environment and the health of personnel.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Reference Figures 1 to 4 This utility model provides a cotton purchasing impurity pre-cleaning device, which aims to solve the problem in the prior art that the surface of the cotton cleaning roller is easily blocked by cotton lint and impurities, resulting in reduced cleaning efficiency and inability to operate continuously.

[0033] like Figure 1As shown, the device includes a body 1, which serves as the mounting base and main support structure for the entire device. The device also includes a housing 41, which is fixedly connected to the top of the body 1 to protect the internal working parts. A motor 42 is fixedly connected to one side of the housing 41, and a rotating rod 43 is fixedly connected to the drive end of the motor 42. A roller 45 is located inside the housing 41 and is connected to the rotating rod 43 via a connecting rod 44. The connecting rod 44 is fixedly connected to the outside of the rotating rod 43. After the motor 42 starts, it drives the roller 45 to rotate through the rotating rod 43 and the connecting rod 44. The roller 45 is used to break up cotton and separate impurities. The roller 45 has a cylindrical structure, filter holes are provided on the cylinder wall of the roller 45, and spikes are fixed in an array on the outer surface of the roller 45.

[0034] The anti-clogging mechanism 4 includes a mounting plate 46, which is fixedly connected to the inner wall of the housing 41. A second motor 47 is fixedly connected to one side of the mounting plate 46. A threaded rod 48 is fixedly connected to the drive end of the second motor 47, and the axis of the threaded rod 48 is parallel to the axis of the roller 45. A brush plate 49 is slidably connected to the outside of the threaded rod 48 and abuts against the outer surface of the roller 45. When the second motor 47 drives the threaded rod 48 to rotate, it drives the brush plate 49 to reciprocate along the axial direction of the threaded rod 48, thereby brushing away impurities from the surface of the roller 45.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The disassembly mechanism 3 includes a waste bin 31, which is movably connected inside the machine body 1 and located below the drum 45. The waste bin 31 is used to collect impurities separated from the drum 45.

[0036] Reference Figure 1 and Figure 2 To enable quick assembly and disassembly of the waste bin 31, the auxiliary component 2 includes a guide rail 24 and a slider 25. The guide rail 24 is fixedly connected to the inner bottom wall of the machine body 1. The slider 25 is fixedly connected to the bottom of the waste bin 31 and slides in cooperation with the guide rail 24. This structure allows the waste bin 31 to slide into or out of the machine body 1 by pulling.

[0037] Reference Figure 2The disassembly mechanism 3 also includes a structure for automatically locking and manually releasing the waste bin 31, which is described in detail below: the chassis 32 is fixedly connected to the back of the waste bin 31; the cylinder 33 is fixedly connected to the top of the chassis 32; the upper locking post 34 is fixedly connected to the top of the cylinder 33, and the upper locking post 34 serves as the locking part of the locking structure. In conjunction with the above structure, a round rod 36 is fixedly connected to a groove inside the machine body 1; a locking block 37 is fixedly connected to the top of the round rod 36. When the waste bin 31 is pushed into place, the locking block 37 is used to lock the upper locking post 34, thereby locking the waste bin 31; a spring 38 is sleeved on the outside of the round rod 36, and the spring 38 provides a restoring force to the locking block 37, keeping it in the locked position. The disassembly mechanism 3 also includes a movable column 35, which is slidably connected to the cylinder 33 and is linked with the waste bin 31. When the waste bin 31 needs to be pulled out, the operator pulls the waste bin 31 to drive the movable column 35. The movable column 35 acts on the locking block 37 and compresses the spring 38, causing the locking block 37 to disengage from the locking column 34, thereby releasing the waste bin 31 and achieving quick disassembly.

[0038] Auxiliary component 2 also includes a feed plate 22;

[0039] Reference Figure 1 The feed plate 22 is fixedly connected to the upper part of the machine body 1 and is inclined. Its function is to guide the cotton to be cleaned to slide smoothly into the cleaning area where the roller 45 is located. The discharge port 23 is opened on the machine body 1 and is located on the other side of the roller 45 away from the feed plate 22. The clean cotton after being cleaned by the roller 45 is transported to the discharge port 23 and discharged under the action of the rotation of the roller 45 and the airflow. The door 21 is connected to the machine body 1 by a hinge. The door 21 is used to close the opening where the waste bin 31 slides in or out, thereby ensuring the cleanliness and environmental protection of the entire working process.

[0040] The implementation principle of this application embodiment is as follows: The cotton to be cleaned slides into the outer shell 41 fixed on the top of the machine body 1 through the inclined feed plate 22 and falls into the area of ​​the roller 45; at this time, the motor 42 starts, and the drive end of the motor 42 drives the rotating rod 43 to rotate. The rotating rod 43 drives the roller 45 to rotate through the connecting rod 44 which is fixedly connected in a distributed manner; the array of fixed spikes on the outer surface of the roller 45 breaks up the cotton clumps, and the impurities in the cotton pass through the filter holes on the roller 45 under the action of gravity to achieve preliminary separation; while the roller 45 is rotating, the anti-blocking mechanism 4 is activated, and the motor 47 fixed on the mounting plate 46 drives the threaded rod 48 to rotate. Since the brush plate 49 is slidably connected to the outside of the threaded rod 48 and abuts against the outer surface of the roller 45, the rotation of the threaded rod 48 drives the brush plate 49 to reciprocate in a direction parallel to the axis of the roller 45. This reciprocating motion continuously brushes away the cotton lint and impurities attached to the surface of the roller 45 and the filter holes, ensuring that the roller 45 is always unobstructed and realizing continuous operation.

[0041] During the aforementioned separation and unclogging process, all impurities falling from the filter holes and brushed off by the brush plate 49 are collected in the waste bin 31, which is movably connected inside the machine body 1 and located below the roller 45. When the waste bin 31 is full and needs cleaning, the operator first opens the door 21, which is connected by a hinge, and then pulls the waste bin 31 outward. The waste bin 31 slides outward along the guide rail 24, which is fixed to the bottom wall of the machine body 1, via a slider 25 fixed to its bottom. When pulled, the chassis 32, which is fixed to the back of the waste bin 31, moves the cylinder 33 along with it. The movable column 35, which is slidably connected to the cylinder 33, acts in conjunction with and on the locking block 37, forcing the locking block 37 to compress the spring 38 sleeved on the outside of the cylindrical rod 36. This causes the locking block 37, which is fixed to the top of the cylindrical rod 36, to disengage from the locking state of the upper locking column 34. The upper locking column 34 is then fixed to the top of the cylinder 33. At this point, the lock is released, and the waste bin 31 is pulled out smoothly. After cleaning, the waste bin 31 is pushed back along the guide rail 24. The spring 38 automatically resets and pushes the locking block 37 to re-lock the upper locking column 34, achieving automatic locking. Finally, the door 21 is closed, restoring the device to a sealed state.

[0042] The cotton that has been broken up and cleaned is conveyed to the discharge port 23, which is located on the machine body 1 on the other side of the roller 45 away from the feed plate 22, under the continuous rotation of the roller 45 and the action of the internal airflow, and discharged from the machine body 1, thus completing the entire cotton impurity pre-cleaning process.
