Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically to a cotton combing device. Background Technology

[0002] In cotton processing, the carding device is a key piece of equipment determining the quality and efficiency of cotton fiber carding. Existing carding devices mostly employ a single cylinder and single carding cover structure, meaning one cylinder is equipped with one carding cover, which operates cyclically, carding through contact between the carding cloth and the cylinder surface. However, this traditional structure results in low utilization of the carding area. Only one side of the carding cover contacts the cylinder surface for carding, while the other side remains idle on the return trip. This means that with the same equipment resources, the actual area used for carding is less than half of the total effective area of ​​the chain plate, failing to fully realize the equipment's capacity potential. In large-scale cotton processing scenarios, this leads to an invisible waste of resources.

[0003] Therefore, how to provide a new cotton combing device that can achieve efficient utilization of the upper and lower layers of the combing cover is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0014] Preferably, it also includes a slider, and an elongated hole is provided on the side wall of the frame along the height direction of the frame. There are two sliders and two elongated holes, which are respectively arranged to correspond to the first driven wheel and the second driven wheel. The slider and the elongated hole are slidably connected along the height direction of the frame, and the first driven wheel and the second driven wheel are rotatably connected to their corresponding sliders.

[0015] Preferably, the combing and impurity removal chain plate includes multiple support strips and a timing belt for connecting the multiple support strips. The support strips are fixedly connected to the outer surface of the closed kinematic chain structure of the combing and impurity removal chain plate with needle cloth. The two ends of the support strips are rotatably connected to the side wall of the timing belt and abut against the guide surface.

[0016] Preferably, the combing and impurity removal chain plate also includes rollers, which are rotatably connected to both ends of the support strip along the length of the support strip, and the wheel surface of the roller contacts and abuts the guide surface.

[0017] Preferably, two rollers are arranged at each end of the support strip along its length and are symmetrically arranged at the center of the support strip's width.

[0047] More specifically, there are four sets of mounting plates 55 and adjusting nuts 56, which are arranged corresponding to the four elongated holes 11.

[0048] In this embodiment, the combing and impurity removal chain plate 4 includes multiple support plates 41 and a timing belt 42 for connecting the multiple support plates 41. The support plates 41 are fixedly connected to the outer surface of the closed motion chain structure of the combing and impurity removal chain plate 4 with needle cloth. The two ends of the support plates 41 are rotatably connected to the side wall of the timing belt 42 and abut against the guide surface.

[0049] In other specific embodiments, the combing and impurity removal chain plate 4 further includes rollers 43, which are rotatably connected to both ends of the support strip plate 41 along the length direction of the support strip plate 41, and the wheel surface of the rollers 43 contacts and abuts against the guide surface. Therefore, the design of the rollers 43 can effectively reduce the coefficient of friction between the combing and impurity removal chain plate 4 and the guide surface, reduce the frictional resistance of the chain plate 4 during movement, and reduce energy consumption.

[0050] Specifically, rotating columns 46 are fixedly connected to both ends of the support strip 41 along its length direction, and rotating holes 421 corresponding to the rotating columns 46 are opened on the side wall of the synchronous belt 42.

[0052] In some specific embodiments, two rollers 43 are respectively arranged at both ends of the support strip 41 along its length direction and are arranged symmetrically at the center of the width direction of the support strip 41.

[0053] In one embodiment, a reinforcing strip 44 is further included, which is fastened to another surface of the support strip 41 to which the needle cloth is fixed. Thus, the stiffness of the support strip 41 structure is enhanced by the reinforcing strip 44.

[0054] Specifically, the reinforcing strip 44 is made of aluminum profile and is used to increase the strength of the support strip 41 in the thickness direction.

[0055] In one embodiment, toothed blocks 45 are fastened to the plate surface of the support plate 41, which is fixedly connected to the reinforcing strip 44, near both ends. The first drive wheel 511, the first driven wheel 512, the second drive wheel 521, and the second driven wheel 522 all have toothed grooves that mesh with the toothed blocks 45. This meshing connection between the toothed blocks 45 and the sprockets ensures the transmission accuracy and stability between the combing and impurity removal chain plate 4 and the sprocket assembly 5, preventing slippage or tooth skipping during chain plate 4 movement, and improving the movement accuracy and synchronization of the chain plate 4. This meshing transmission structure can also transmit a large torque, ensuring reliable operation of the chain plate 4 under high-speed, heavy-load conditions, and meeting the power transmission requirements of the cotton combing device in actual production.

[0056] Specifically, the guide plate assembly also includes a front guide plate 33 and a rear guide plate 34. Both the front guide plate 33 and the rear guide plate 34 are fixedly connected to the inner wall of the frame 1. The front guide plate 33 is located between the first drive wheel 511 and the second driven wheel 522 and supports and guides the position of the support strip 41 located between the two. The rear guide plate 34 is located between the first driven wheel 512 and the second drive wheel 521 and supports and guides the position of the support strip 41 located between the two.

[0058] Specifically, it also includes a chain plate cleaning assembly, which includes a stripping roller 71, a high-speed crushing roller 72, and a dust collection channel 73. During the movement of the combing and impurity removal chain plate 4, it grabs the short fibers and impurities of the cotton layer on the surface of the cylinder 2. After grabbing, it continues to move. When passing through the chain plate cleaning assembly, the stripping roller 71 peels off the short fibers and impurities grabbed on the combing and impurity removal chain plate 4, and then the high-speed crushing roller 72 breaks them up before they are discharged through the dust collection channel 73.

[0059] Specifically, the structure of the chain plate cleaning assembly, its cooperation with the cylinder 2, and the cooperation between the components are existing technologies and will not be elaborated here.

[0060] More specifically, there are two chain plate cleaning components, which are arranged corresponding to the front guide plate 33 and the rear guide plate 34 respectively.

[0061] More specifically, the front guide plate 33 and the rear guide plate 34 can provide stable support for the support bar 41 during the chain cleaning process.

[0062] The specific principle and usage method of the cotton combing device provided in this embodiment are as follows:

[0063] Cooperative carding with dual cylinders and a carding and impurity removal chain plate: This device uses a combination of two cylinders 2 (upper and lower) and a carding and impurity removal chain plate 4. The two cylinders 2 are spaced apart along the height of the frame 1 and are rotatably connected to the frame 1. The carding and impurity removal chain plate 4 is located between the two cylinders 2 and is a closed kinematic chain structure. The outer chain plate layer of the carding and impurity removal chain plate 4 is fixedly connected to the carding cloth, and the two side edges of the upper and lower layers abut against the guide surfaces of the upper guide plate 31 and the lower guide plate 32, respectively. When the carding and impurity removal chain plate 4 moves, its carding cloth contacts the surface of the cylinders 2, simultaneously carding and removing impurities from the cotton layers covered by the two cylinders 2. This design breaks through the limitations of the traditional single cylinder and single carding cover structure, enabling the carding and impurity removal chain plate 4 to simultaneously card and remove impurities from both cylinders 2, greatly improving the utilization rate of the carding and impurity removal chain plate 4, multiplying the carding area, effectively improving carding quality and production efficiency, reducing equipment resource waste, and is especially suitable for large-scale cotton processing scenarios, with significant economic benefits.
