Description

Technical Field

[0001] This utility model relates to the technical field of silk combing and cutting hemp machines, and in particular to a feeding mechanism for a silk combing and cutting hemp machine. Background Technology

[0002] In the field of ramie carding technology, efficient and precise processing is crucial for improving the quality of ramie fibers. Ramie silk carding aims to process degummed and bleached ramie into softer and finer fibers through specific techniques. In this process, the feeding stage of the carding and cutting machine plays a key role.

[0003] Currently, traditional feeding methods rely heavily on manual operation. Workers need to manually spread the refined hemp at the feed inlet of the hemp cutter to ensure uniform thickness for subsequent cutting and combing. However, this manual feeding mode has many drawbacks: on the one hand, manual spreading is labor-intensive, and prolonged operation can easily lead to worker fatigue, affecting the stability and consistency of the feeding; on the other hand, the feed inlet of the hemp cutter is mostly an open structure, with workers directly contacting moving parts during the feeding process, posing a significant safety hazard; simultaneously, traditional feeding mechanisms lack effective pre-treatment, and the refined hemp often suffers from problems such as stacking, wrinkling, and fiber clumping before entering the hemp cutter, resulting in inconsistent quality of the cut hemp segments and severely impacting the combing efficiency of the subsequent circular combing machine. In addition, existing equipment has poor adaptability to refined hemp of different thicknesses, making it difficult to flexibly adjust feeding parameters according to raw material characteristics, limiting the equipment's versatility and processing range. These problems not only reduce overall production efficiency but also increase production costs and safety risks. Therefore, we propose a silk-type combing and cutting hemp feeding mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding mechanism for a silk-type combing and cutting hemp machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding mechanism for a silk-type combing and cutting hemp includes a cutting machine body. A feeding platform for carrying the refined hemp to be processed is provided on one side of the cutting machine body. A pressure roller assembly for pre-pressing and flattening the refined hemp to avoid stacking and wrinkling is provided on one side of the top of the feeding platform. A combing assembly for combing and dispersing the refined hemp to ensure uniform feeding is provided on the top of the feeding platform and on the other side of the pressure roller assembly.

[0007] As a preferred embodiment of this utility model, the hemp cutting machine body has a feed inlet on one side for pre-treated dried hemp to enter, and a discharge outlet on the other side for the finished hemp segments to be output.

[0008] As a preferred embodiment of this utility model, the pressure roller assembly includes a first mounting cavity opened on one side of the top of the hemp cutting machine body, a first rotating shaft is provided in the first mounting cavity, a first roller is sleeved on the first rotating shaft, and a first drive motor is provided on the other side of the back of the feeding platform, with its output end being connected to the first rotating shaft for transmission.

[0009] As a preferred embodiment of this utility model, a support frame is provided on the top of the feeding platform and on the front and back of the first mounting cavity, and an mounting frame is provided inside the support frame and above the first mounting cavity. A second roller is rotatably connected inside the mounting frame.

[0010] As a preferred embodiment of this utility model, the top of the support frame is provided with a hydraulic cylinder, the output end of which is fixedly connected to the mounting frame. The top of the support frame is slidably connected to both the front and back sides, and one bottom end of the auxiliary guide rod is fixedly connected to the mounting frame.

[0011] As a preferred embodiment of the present invention, the combing assembly includes a second mounting cavity opened at the top of the feeding platform, a plurality of second rotating shafts are provided in the second mounting cavity, a third roller is sleeved on each of the plurality of second rotating shafts, and a plurality of combing rake teeth are arranged around the outer surface of the plurality of third rollers.

[0012] As a preferred embodiment of this utility model, one end of the back of a plurality of second rotating shafts extends out to the back of a feeding platform and is connected to a rotating disk. The plurality of rotating disks are connected by belts. The back of the feeding platform is provided with a housing, and the back of the housing is provided with a second drive motor, the output end of which is connected to one of the rotating disks.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the design of the feeding platform provides a stable foundation for the bearing and conveying of refined hemp, avoiding the feeding chaos caused by unstable placement during manual feeding. At the same time, the combined use of the feeding platform with the pressure roller assembly and the carding assembly realizes a continuous process from bearing to pre-treatment of refined hemp, reducing manual intervention and lowering the labor intensity of workers.

[0015] Through the design of the first roller, second roller, and first drive motor in the pressure roller assembly, the first drive motor provides power to the first roller, enabling it to actively convey refined hemp, replacing manual pushing and improving the automation level of feeding; with the cooperation of hydraulic cylinder and auxiliary guide rod, the distance between the second roller and the first roller can be flexibly adjusted to adapt to the processing needs of refined hemp of different thicknesses, enhancing the versatility and flexibility of the equipment, while ensuring the consistency of pre-pressing and flattening effect.

[0016] Through the design of the third roller, combing rake teeth, and second drive motor in the combing assembly, the second drive motor drives multiple third rollers to rotate synchronously. The combing rake teeth thoroughly comb and break up the refined hemp, effectively removing fiber clumps and making the fiber distribution more uniform, providing high-quality raw materials for subsequent hemp cutting processing. With the cooperation of the rotating disc and belt, multiple third rollers operate synchronously, ensuring the uniformity of the combing action and avoiding differences in combing effect caused by different rotation speeds of each roller, further improving combing efficiency.

[0017] With the coordinated action of the feeding platform, pressure roller assembly, and carding assembly, the stability and efficiency of the entire feeding process are greatly improved, providing a reliable feeding guarantee for the entire silk combing and cutting process and improving the quality of the final product.

[0027] Example

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: a feeding mechanism for a silk-type combing and cutting hemp, including a cutting machine body 1, a feeding platform 2 for carrying the fine hemp to be processed is provided on one side of the cutting machine body 1, a pressure roller assembly 3 for pre-pressing and flattening the fine hemp to avoid stacking and wrinkling is provided on one side of the top of the feeding platform 2, and a combing assembly 4 for combing and dispersing the fine hemp to ensure uniform feeding is provided on the top of the feeding platform 2 and on the other side of the pressure roller assembly 3.

[0029] Through the coordinated operation of the feeding platform 2, the pressure roller assembly 3, and the combing assembly 4, a continuous process from bearing to pre-treatment and then to conveying of the refined hemp is realized. The pre-pressing and flattening function of the pressure roller assembly 3 avoids the refined hemp from being affected by stacked wrinkles, thus ensuring the quality of subsequent processing. The combing and dispersing function of the combing assembly 4 ensures the uniform feeding of the hemp cutting machine body 1. The three components together improve the stability and efficiency of the entire feeding process, reduce manual intervention, and lower labor intensity.

[0030] The main body 1 of the hemp cutting machine is provided with a feed inlet 101 on one side for pre-treated dried hemp to enter, and a discharge outlet 102 on the other side for the hemp segments to be cut out.

[0031] The pressure roller assembly 3 includes a first mounting cavity 301 located on one side of the top of the hemp cutting machine body 1. A first rotating shaft 302 is provided inside the first mounting cavity 301, and a first roller 303 is sleeved on the first rotating shaft 302. A first drive motor 304 is provided on the other side of the back of the feeding platform 2, and its output end is connected to the first rotating shaft 302. The first mounting cavity 301 provides a stable mounting space for the first rotating shaft 302 and the first roller 303, ensuring their structural stability during operation. The first drive motor 304 provides power for the rotation of the first roller 303 through the transmission connection with the first rotating shaft 302, enabling the first roller 303 to actively convey refined hemp, replacing manual pushing and improving the automation level of feeding. The rotational conveying function of the first roller 303 ensures that the refined hemp can smoothly enter the subsequent processing stage at a certain speed, enhancing the controllability of the feeding process.

[0032] A support frame 305 is provided on the top of the feeding platform 2 and on the front and back of the first mounting cavity 301. A mounting frame 306 is provided inside the support frame 305 and above the first mounting cavity 301. A second roller 307 is rotatably connected inside the mounting frame 306. The support frame 305 provides reliable support for the mounting frame 306 and the second roller 307, ensuring the structural stability of the second roller 307 when working with the first roller 303. The mounting frame 306 enables the flexible installation of the second roller 307, allowing it to form a clamping structure with the first roller 303. The cooperation between the second roller 307 and the first roller 303, through their relative rotation, achieves the clamping and conveying of the refined hemp, further enhancing the stability of the conveying, preventing the refined hemp from slipping or deviating during the conveying process, and ensuring the consistency of pre-compression flatness and conveying effect.

[0033] A hydraulic cylinder 308 is provided on the top of the support frame 305, and its output end is fixedly connected to the mounting frame 306. An auxiliary guide rod 3061 is slidably connected to the top of the support frame 305 near both the front and back sides. One end of the auxiliary guide rod 3061 is fixedly connected to the mounting frame 306. The hydraulic cylinder 308 can drive the mounting frame 306 to move up and down, thereby adjusting the distance between the second roller 307 and the first roller 303. This function enables the pressure roller assembly 3 to adapt to the processing requirements of fine hemp of different thicknesses, improving the versatility and flexibility of the equipment. The auxiliary guide rod 3061 plays a guiding and auxiliary support role during the movement of the mounting frame 306, enhancing the stability of the mounting frame 306 during movement, avoiding tilting or swaying of the mounting frame 306 during up and down movement, ensuring the accuracy of the distance adjustment between the second roller 307 and the first roller 303, thereby ensuring the pre-pressing and flattening effect of fine hemp of different thicknesses.

[0034] The carding assembly 4 includes a second mounting cavity 401 located at the top of the feeding platform 2. Multiple second rotating shafts 402 are housed within the second mounting cavity 401, and each of the second rotating shafts 402 is fitted with a third roller 403. Multiple sets of carding rakes 404 are arranged around the outer surface of the multiple third rollers 403. The second mounting cavity 401 provides installation space for components such as the second rotating shafts 402 and the third rollers 403, ensuring the overall structural stability of the carding assembly 4. During rotation, the carding rakes 404 on the multiple third rollers 403 can thoroughly card and break up the refined hemp, effectively removing clumps and making the hemp fibers more evenly distributed. The multiple sets of carding rakes 404 enhance the carding effect, ensuring good uniformity of the carded refined hemp when it enters the hemp cutting machine body 1, providing high-quality raw materials for subsequent cutting and improving the cutting quality of the hemp segments.

[0035] Multiple second rotating shafts 402 extend from one end of their back to the back of the feeding platform 2, which is connected to a rotating disk 4021. The multiple rotating disks 4021 are connected by belts. The back of the feeding platform 2 is provided with a housing 405, and the back of the housing 405 is provided with a second drive motor 4051. Its output end is connected to one of the rotating disks 4021. The cooperation between the rotating disk 4021 and the belt enables the synchronous rotation of multiple second rotating shafts 402, ensuring that multiple third rollers 403 can work together. This makes the combing action of the combing rake 404 on the refined hemp more uniform and consistent, avoiding the difference in combing effect caused by the different rotation speeds of each roller. The second drive motor 4051 provides power for the operation of the entire combing assembly 4. The synchronously rotating third rollers 403 and combing rake 404 further improve the combing efficiency, ensuring that the refined hemp can be combed and dispersed quickly and effectively.

[0036] The working process of this utility model is as follows: When using the feeding mechanism of a silk-type combing and cutting hemp machine, the operator places the dried hemp to be processed on the feeding platform 2. The feeding platform 2 serves as a supporting foundation, providing a stable placement space for the dried hemp and ensuring that the dried hemp can enter the subsequent processing stage in an orderly manner. The dried hemp on the feeding platform 2 is first conveyed to the pressure roller assembly 3. The first drive motor 304 is started and drives the first roller 303 to rotate through the transmission connection with the first rotating shaft 302. At the same time, the hydraulic cylinder 308 drives the mounting frame 306 to move up and down according to the thickness of the dried hemp, adjusting the distance between the second roller 307 and the first roller 303. The auxiliary guide rod 3061 ensures the stability of the mounting frame 306 during its movement. Subsequently, the second roller 307 rotates relative to the first roller 303 under the drive of the dried hemp.

[0037] The relative rotation of the first roller 303 and the second roller 307 enables the clamping and conveying of the refined hemp. During the conveying process, the refined hemp is pre-pressed and flattened to avoid the refined hemp from being affected by stacking wrinkles and affecting the quality of subsequent processing. The adjustable spacing allows the component to adapt to refined hemp of different thicknesses, enhancing the versatility of the equipment, while stable conveying ensures that the refined hemp can move forward smoothly at a certain speed.

[0038] The fine hemp, pre-pressed and flattened by the pressure roller assembly 3, is conveyed to the carding assembly 4. After the second drive motor 4051 starts, its output end drives the rotating disk 4021 connected to it to rotate. Since the multiple rotating disks 4021 are connected by belts, all rotating disks 4021 rotate synchronously, thereby driving multiple second rotating shafts 402 and the third roller 403 sleeved on them to rotate together. The multiple sets of carding rake teeth 404 on the outer surface of the third roller 403 rotate with the roller.

[0039] The rotating combing rake teeth 404 thoroughly comb and disperse the pre-compressed ramie, effectively removing any lumps that may exist in the ramie and making the fibers that may have gathered or tangled disperse evenly. This lays a good foundation for subsequent processing in the ramie cutting machine body 1, ensuring that the ramie entering the next stage has a uniform texture.

[0040] After being processed by the combing component 4, the refined hemp enters the hemp cutting machine through the feed inlet 101 on one side of the hemp cutting machine body 1 under the action of conveying. The cut hemp segments are then output through the discharge outlet 102 on the other side.

[0041] Through the above process, the feeding platform 2, the pressure roller assembly 3, the combing assembly 4, and the feed inlet 101 and discharge outlet 102 of the hemp cutting machine body 1 cooperate with each other to realize the continuous operation of the refined hemp from bearing, pre-compression, combing to conveying to the hemp cutting machine. This greatly improves the stability and efficiency of the feeding process, reduces manual intervention, lowers labor intensity, and provides a reliable feeding guarantee for the entire silk combing and cutting process.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
