Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to an impurity conveying device. Background Technology

[0002] The cotton opening and carding combined system is a joint production system that directly connects the cotton opening and carding processes in traditional textile technology through cotton conveying pipelines and electromechanical control systems. Its core function is to shorten the process flow, save labor costs, and realize continuous and automated processing of raw cotton from opening to carding.

[0003] In combing and cleaning equipment, the impurity conveying device is used to transport the dust and impurities separated from the opened fibers to the dust filtration system. In existing technology, the impurity conveying device typically consists of a collection pipe and a conveying pipe, relying on the negative pressure of the dust filtration system to adsorb the dust and impurities. However, this structure has the following problems:

[0004] Dust and debris accumulation: Dust and debris easily accumulate at the connection between the collection pipe and the delivery pipe, requiring increased air volume and air pressure for cleaning, resulting in a significant increase in energy consumption;

[0005] Fiber waste: High negative pressure can easily cause dust and impurities to mix into the fibers and be sucked away (i.e., the "whitening" phenomenon), resulting in waste of raw materials.

[0006] Therefore, there are still shortcomings and deficiencies in the existing technology. How to provide an impurity conveying device that can reduce dust and impurity accumulation and avoid waste of raw materials is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide an impurity conveying device that solves the technical problem that existing impurity conveying devices, which are usually composed of a collection pipe and a conveying pipe, suffer from dust and impurity accumulation and fiber waste during use.

[0008] To achieve the above objectives, this utility model provides an impurity conveying device, comprising:

[0017] The driven roller is fixed at both ends to the two mounting plates respectively.

[0018] Preferably, the support has two limiting guide grooves along the horizontal direction, and the upper and lower sides of the mounting plate are respectively accommodated in the two limiting guide grooves.

Detailed Implementation

[0032] 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.

[0033] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] This utility model provides an impurity conveying device, in which impurities fall onto the conveyor belt 22 by their own weight and are conveyed and discharged by the conveyor belt 22, which can effectively reduce dust accumulation inside the equipment and ensure a clean workshop environment.

[0035] Please refer to this as well. Figures 1 to 4 The impurity conveying device provided by this utility model includes:

[0036] Two supports 10 are used to fix the two side wall panels inside the combing and cleaning equipment;

[0037] The driving roller 20 and the driven roller 21 are rotatably disposed between two supports 10, and a conveyor belt 22 is provided between the driving roller 20 and the driven roller 21 for transmission; wherein, the conveyor belt 22 is an annular conveyor belt 22, which is horizontally tensioned between the driving roller 20 and the driven roller 21, and the conveyor belt 22 is moved by the rotation of the driving roller 20 and the driven roller 21.

[0038] The support plate 30 is located in the annular space formed by the conveyor belt 22. The top of the support plate 30 is close to the bottom of the conveyor belt 22, and the two sides of the support plate 30 are fixedly connected to two supports 10 respectively.

[0039] Two seals 40 are located on both sides of the conveyor belt 22. The seals 40 have an L-shaped structure. One side of the seal 40 is fixed to the support 10, and the other side is in close contact with the top surface of the conveyor belt 22.

[0040] In use, the impurity conveying device is fixedly installed on the side wall panels inside the cleaning and combing equipment via two supports 10. Impurities fall onto the conveyor belt 22 by their own weight. By setting up support plates 30, the conveyor belt 22 is prevented from sinking due to its own weight when impurities fall onto it. As the drive roller 20 and driven roller 21 rotate, the impurities falling on the conveyor belt 22 are conveyed forward. During the forward conveying of impurities, the gap between the conveyor belt 22 and the supports 10 is sealed by the seals 40 set on both sides of the conveyor belt 22, preventing impurities from falling into the gap between the conveyor belt 22 and the supports 10.

[0041] With this setup, dust and debris are transported by their own weight and the conveyor belt 22, effectively reducing dust accumulation inside the equipment, ensuring a clean workshop environment, reducing reliance on the negative pressure of the dust filtration system, reducing the phenomenon of fibers being accidentally sucked in, avoiding fiber waste, and significantly reducing energy consumption.

[0042] Optionally, the seal 40 has a flexible scraper on the side that is in close contact with the top surface of the conveyor belt 22. The flexible scraper is made of wear-resistant rubber. With this setting, the flexible scraper can adapt to the slight deviation or vibration of the conveyor belt 22, further preventing small impurities from seeping into the gap and improving the reliability of the seal.

[0043] Please refer to this as well. Figures 1 to 4 The impurity conveying device provided by this utility model also includes a tension adjusting device 50, which includes:

[0044] Two mounting plates 51 are movably mounted on two supports 10, respectively;

[0045] The bracket 52 is fixedly mounted on the support 10 and is located near the driven roller 21.

[0046] The screw 53 is set in a horizontal direction. One end is fixedly connected to two mounting plates 51, and the other end passes through the bracket 52 and is locked and fixed by the locking member 54.

[0047] The driven roller 21 is fixed at both ends to two mounting plates 51.

[0048] The bracket 52 is roughly U-shaped, and its upper and lower sides are fixedly connected to two supports 10 respectively. It should be understood that the bracket 52 has through holes at the upper and lower parts of the side where the screw 53 is located, for the conveyor belt 22 to pass through. This ensures that when the driving roller 20 and the driven roller 21 work to drive the conveyor belt 22, the bracket 52 will not interfere with or affect the movement of the conveyor belt 22.

[0049] By unlocking the locking element 54, the screw 53 can slide horizontally along the bracket 52, thereby driving the mounting plate 51 to move horizontally, changing the position of the driven roller 21, and thus changing the distance between the driving roller 20 and the driven roller 21, adjusting the tension of the conveyor belt 22. After adjustment, the locking element 54 can be used to re-lock and fix the belt.

[0050] With this setup, the tension of the conveyor belt 22 is not only adjustable, but also easy to operate, saving operation time and improving work efficiency.

[0051] In some embodiments, the support 10 is provided with two limiting guide grooves in the horizontal direction, and the upper and lower sides of the mounting plate 51 are respectively accommodated in the two limiting guide grooves.

[0052] By setting a limit guide groove, the tension of the conveyor belt 22 can be adjusted to guide the movement of the mounting plate 51, ensuring that the screw 53 drives the mounting plate 51 to move in the horizontal direction, thus improving the stability of movement.

[0053] Optionally, both ends of the limiting guide groove are provided with blocks. By setting the blocks, the blocking effect can be achieved to prevent the mounting plate 51 from sliding out from both ends of the limiting guide groove during the movement of the mounting plate 51 along the limiting guide groove.

[0054] In some of these embodiments, please refer to the following: Figures 1 to 2 The locking element 54 includes two nuts that are threaded to the screw 53, and the two nuts are located on both sides of the bracket 52.

[0055] In use, the two nuts are respectively pressed against both sides of the bracket 52 to lock and fix the screw 53. When adjusting the tension of the conveyor belt 22, the screw 53 can be moved horizontally by loosening the nuts, so as to drive the mounting plate 51 to move horizontally and change the distance between the driving roller 20 and the driven roller 21.

[0056] In some embodiments, a washer is provided between the nut and the bracket 52, and the washer is sleeved on the screw 53.

[0057] Since the nut applies concentrated pressure to the surface of bracket 52 when it is tightened, the use of shims can prevent local deformation or scratches on bracket 52, reduce wear, and extend service life.

[0058] In some of these embodiments, please refer to the following: Figures 1 to 2 A horizontally arranged connecting rod 511 is fixed between the two mounting plates 51. The connecting rod 511 is perpendicular to the screw 53, and the screw 53 is fixedly connected to the connecting rod 511.

[0059] The screw 53 is fixedly connected to the two mounting plates 51 via the connecting rod 511, so that when the screw 53 moves, it can drive the two mounting plates 51 to move synchronously through the connecting rod 511, avoiding excessive displacement of the driven roller 21 and ensuring normal use.

[0060] In some embodiments, the connection between the screw 53 and the connecting rod 511 is located in the middle of the connecting rod 511.

[0061] When the screw 53 drives the connecting rod 511, the central connection point ensures a symmetrical distribution of the driving force on both mounting plates 51, preventing stress concentration or deformation on one side due to offset. This arrangement eliminates the rotational torque caused by asymmetrical connection, maintaining the linear movement trajectory of the driven roller 21. Furthermore, the central connection point ensures synchronous driving force transmission from the screw 53 to the two mounting plates 51, preventing speed differences between the two mounting plates 51 due to connection position misalignment, further ensuring synchronicity.

[0062] In some of these embodiments, please refer to the following: Figures 1 to 2 A support roller 60 is provided below the conveyor belt 22.

[0063] By setting the support roller 60, the conveyor belt 22 can be supported, ensuring that the conveyor belt 22 maintains a stable shape and avoiding excessive sagging or deformation due to gravity.

[0064] Optionally, the support roller 60 is coated with an anti-stick coating and equipped with a rotating brush. The rotating brush rotates with the support roller 60 to continuously clean the dust adhering to the surface of the conveyor belt 22, preventing impurities from sticking back and ensuring the cleanliness and stability of the conveyor belt 22 during long-term operation.

[0065] In some of these embodiments, please refer to the following: Figures 1 to 4 The impurity conveying device provided by this utility model also includes a drive device for driving the active roller 20 to rotate. The drive device includes a reducer 70, and the output shaft of the reducer 70 is connected to the active roller 20 through a belt drive mechanism or a chain drive mechanism.

[0066] The input shaft of the reducer 70 is connected to a power source such as a motor, and the output shaft of the reducer 70 is connected to the drive roller 20 through a transmission mechanism. When working, the drive roller 20 is driven to rotate, which drives the conveyor belt 22 to move and transport the impurities that fall on the conveyor belt 22 forward.

[0067] The specific working process of the impurity conveying device provided by this utility model is as follows: First, the impurity conveying device is fixedly installed on the two side wall panels inside the cleaning and combing equipment. Impurities fall onto the conveyor belt 22 by their own weight. As the driving roller 20 and the driven roller 21 rotate, the conveyor belt 22 moves and conveys the impurities falling on the conveyor belt 22 forward. During the forward conveying process, the sealing elements 40 provided on both sides of the conveyor belt 22 seal the gap between the conveyor belt 22 and the support 10, preventing impurities from falling into the gap between the conveyor belt 22 and the support 10. Finally, the impurities enter the dust filtration system from the front end of the conveyor belt 22 in the conveying direction for subsequent processing.

[0068] Using the aforementioned impurity conveying device, dust and impurities are transported mechanically by their own weight and the conveyor belt 22, effectively reducing dust accumulation inside the equipment, ensuring a clean workshop environment, reducing reliance on the negative pressure of the dust filtration system, reducing the phenomenon of fiber being accidentally sucked in, avoiding fiber waste, and significantly reducing energy consumption. The impurity conveying device features a modular design, facilitating disassembly and assembly and adapting to different models.

[0069] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0070] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
