[0001] The utility model relates to the technical field of natural fiber composite materials, in particular to a gradient beater mechanism for combing bamboo fibers. Background Art

[0002] In the preparation process of bamboo fiber felt / board, bamboo fibers must be mixed, unpacked and loosened before the first combing into a web; combing is a pre-treatment procedure, which mainly uses a combing machine to remove impurities and solve the problems of uneven length and easy entanglement of bamboo fibers. With the high-yield development of composite material technology and equipment and the application of bamboo fibers, the matching combing machines also need to have higher technical standards. Designing a combing machine suitable for the production and processing of the entire bamboo fiber felt / board to meet the requirements of subsequent process settings has become a new development direction for the industry.

[0003] Usually, the technical defects of the carding machine are: the single drum knife gear of the carding machine has poor carding uniformity, bamboo fibers are easy to knot, have different lengths, and are unevenly dispersed, which affects the subsequent process treatment effect and production efficiency. Therefore, it is urgent to improve the related structure of the drum knife gear of the carding machine. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and provide a gradient beater mechanism for combing bamboo fibers. The gradient beater mechanism is applied to a carding machine to comb bamboo fibers and cut overlong bamboo fibers into predetermined lengths, thereby solving the technical problems that the existing carding machine drum knife gear combs bamboo fibers with poor uniformity, bamboo fibers are easy to knot, have different lengths, and are unevenly dispersed.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0006] A gradient beater mechanism for combing bamboo fibers comprises a conveyor belt, wherein the conveyor belt is provided with a plurality of bamboo fiber processing sections arranged in a gradient from front to back, the bamboo fibers are placed on the conveyor belt and can move from front to back along with the conveyor belt, each bamboo fiber processing section is provided with at least one beater unit, the beater unit comprises a cylinder, a combing needle and a cutter, the cylinder is located above the conveyor belt, the axis of the cylinder is parallel to the surface of the conveyor belt and the axis of the cylinder is perpendicular to the moving direction of the conveyor belt, a plurality of combing needles are distributed on the surface of the cylinder, the cylinder can rotate under the drive of an external driver, when the combing needles rotate with the cylinder body to the combing needle heads facing downward, the combing needle heads are close to the surface of the conveyor belt and can hook up the bamboo fibers on the surface of the conveyor belt, the cutter is located above the cylinder body, the cutter can move downward periodically, the lower end of the cutter cuts into the gap between two adjacent combing needles, and the bamboo fibers between the two adjacent combing needles are cut off.

[0007] To optimize the technical solution, further improvements were made including:

[0008] The combing needles are distributed on the cylinder at equal intervals along the axial direction of the cylinder or the combing needles are distributed on the cylinder at equal arc lengths along the circumference of the cylinder.

[0009] The root of the combing needle is fixed on the cylinder body, and the head of the combing needle is provided with a hook for hooking the bamboo fiber.

[0010] The combing needle spacing or the combing needle interval arc length of the beater unit in the latter bamboo fiber processing section is smaller than the combing needle spacing or the combing needle interval arc length of the beater unit in the former bamboo fiber processing section.

[0011] An electric gear shifter is installed on the cross beam of the carding machine. The electric gear shifter is connected to the cutter and controls the cutter to move downward periodically.

[0012] The height of the first bamboo fiber processing section is higher than the height of the second bamboo fiber processing section.

[0013] When the combing needle head is close to the surface of the conveyor belt, part of the bamboo fibers are hooked up by the combing needle head, and part of the bamboo fibers are blocked by the combing needle head and rotated, and are combed into a forward and backward direction.

[0015] The rotation speed of the cylinder is 800-1000r / min.

[0016] The electric gear shifter controls the up and down movement of the cutter at a time interval of 1-2 seconds per cutter.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. The beater mechanism of the utility model has a beater unit, each of which is provided with a combing needle capable of grabbing bamboo fibers and a cutter for cutting bamboo fibers. The bamboo fibers must be rolled to the upper part of the drum before they can be cut by the cutter. At the same time, two combing needles simultaneously hook one bamboo fiber to smoothly roll the bamboo fiber to the upper part of the drum. Because when only one combing needle hooks the bamboo fiber, the bamboo fiber will slip from the curved hook gap of the needle head when the combing needle rotates upward halfway, which means that the bamboo fibers grabbed to the upper part of the drum are all longer than the combing needle spacing or the combing needle spacing arc length. The cutting of this part of the bamboo fibers can effectively reduce the excessively long bamboo fibers and alleviate the problem of uneven length of the bamboo fibers.

[0019] 2. The utility model is provided with a plurality of gradients, each of which has a beater unit. The bamboo fibers are processed multiple times by the beater units so that the bamboo fibers have a uniform length and are evenly dispersed to reach a standard length.

[0020] 3. When the combing needle head of the utility model is close to the surface of the conveyor belt, the bamboo fibers that are not hooked up will be blocked by the combing needle head and rotated, combed into a front-to-back direction, so that the bamboo fibers are in the same direction, without lateral winding and knotting, and the production efficiency is high.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0030] The contents disclosed in the prior art documents cited in the specification of the present utility model are all incorporated into the present utility model by reference in their entirety, and are therefore part of the disclosure of the present utility model.

[0031] according to Figure 1 and Figure 2 The utility model provides a gradient beater mechanism for combing bamboo fiber, comprising a conveyor belt 1, wherein the conveyor belt 1 is provided with three gradient bamboo fiber processing sections from front to back, and the bamboo fiber is placed on the conveyor belt 1 and can move from front to back along with the conveyor belt 1, and each bamboo fiber processing section is provided with at least one beater unit, and the beater unit comprises a cylinder 2, a combing needle 3 and a cutter 4,

[0032] The cylinder 2 is cylindrical and is driven to rotate by an external driver. The root of the combing needle 3 is fixed on the cylinder 2. The head of the combing needle 3 is provided with a hook for hooking the bamboo fiber. The cutter 4 is located on the carding machine beam 6 above the cylinder 2. The carding machine beam 6 is equipped with an electric gear shifter, which is connected to the cutter 4. The electric gear shifter controls the cutter 4 to move downward periodically.

[0033] The gradient beater mechanism includes two working principles, one is the axial spacing size gradient beater, and the other is the circumferential spacing size gradient beater. The combing needles 3 of the axial spacing size gradient beater are evenly spaced on the cylinder 2 along the axial direction of the cylinder 2, such as Figure 1 As shown, the combing needles 3 of the circumferential spacing size gradient beater are distributed on the cylinder 2 along the circumference of the cylinder 2 with equal arc lengths, as shown in FIG. Figure 2 shown.

[0034] The axially distributed combing needles 3 are spaced at a length of d. The length of the passing fiber is controlled by changing the size of d. Fibers with a length greater than d will be hooked by two adjacent combing needles 3 and then rolled onto the cylinder 2. Even if fibers with a length less than d are hooked by one combing needle 3, they will slip out of the hook gap when the combing needle 3 rotates upward because of the large gap between the hooks of the combing needles 3, and cannot be rolled onto the cylinder 2. The cylinder 2 rotates at a speed of 960r / min, and the cutter 4 cuts the bamboo fiber from the middle. The remaining fibers are transported to the next axial spacing size gradient beater of different lengths through the conveyor belt 1 for re-cutting and combing.

[0035] The circumferentially distributed combing needles 3 are distributed at intervals of arc length s, and the length of the fibers passing through is controlled by changing the size of s. The circumferentially distributed combing needles 3 process the fibers in a manner similar to that of the axially distributed combing needles 3 .

[0036] The specific operation steps of the utility model are as follows: control the rotating motor through the controller, further control the rotation speed of the cylinder 2, control the rising or falling frequency of the cutter 4 through the controller, and cooperate with the electric gear to control the rotation speed of the axial spacing size gradient beater and the circumferential spacing size gradient beater assembly; load the bamboo fiber into the carding machine and turn on the gradient beater system. The combing needles 3 of the axial spacing size gradient beater distributed along the axial direction of the cylinder 2 grab the bamboo fiber with a length exceeding d, or the combing needles 3 of the circumferential spacing size gradient beater distributed along the circumference of the cylinder 2 grab the bamboo fiber with a length exceeding s, and rotate with the cylinder 2 to the cutter 4. The rotation speed of the cylinder 2 is 960r / min, and the bamboo fiber is cut from the middle, and the remaining fibers are transported to the next axial spacing size gradient beater of different lengths through the conveyor belt 1 for re-cutting and combing. The remaining fibers are transported to the next axial spacing size gradient beater of different lengths through the conveyor belt 1 for re-cutting and combing.

[0037] During the grabbing process, the axial spacing size gradient beater will inevitably collide with the transverse bamboo fibers whose length is less than d. Due to the action of the tangential force of the beater, the original transverse direction of the bamboo fibers becomes the same as the transmission direction, reducing the transverse entanglement phenomenon.

[0038] The beneficial effects of the utility model are as follows: an axial spacing size gradient beater and a circumferential spacing size gradient beater are adopted, a rotating device is arranged in the cylinder 2, and a lifting device is arranged on the cutter 4; the structure is simple, the use is convenient, the combing effect is good, the length of the bamboo fibers is consistent, the standard length is achieved, the direction is consistent, there is no lateral entanglement phenomenon, and the production efficiency is high.

[0039] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should be regarded as the protection scope of the utility model.
