Description

Technical Field

[0001] This utility model relates to the technical field of cotton mixing boxes, and in particular to the technical field of density control devices for the final cotton mixing box. Background Technology

[0002] The main function of the blending box is to mix and homogenize fibers, and to minimize fiber damage, thereby ensuring the stability of the subsequent production line and product quality.

[0003] Traditional cotton blending boxes primarily rely on fiber characteristics and blending requirements, considering factors such as the number of blending passes and adjustment parameters of working elements (e.g., element spacing and relative speed) to ensure uniform fiber mixing. However, this often fails to meet the requirements for uniform fiber distribution in high-quality products. As shown in patent document CN104372456A, existing pneumatic cotton boxes cannot control fiber density. Therefore, it is necessary to develop a cotton box density control device with controllable fiber density and more uniform pneumatic cotton box pressure, which can provide a stable fiber supply for the next process, making production more stable. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a final cotton box density control device that can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes a final cotton box density control device, comprising a cotton box, wherein the cotton box is provided with a cotton inlet, a vibrating plate, a roller, a beater and a cotton outlet in sequence from top to bottom. The vibrating plate is located on both sides of the cotton box, and a mounting frame is provided on the inner wall of the cotton box. The top of the vibrating plate rotates on the mounting frame, and the bottom of the vibrating plate is inclined downward toward the roller. The vibrating plate and the cotton box are connected by a spring, and a vibrator is installed on the vibrating plate.

[0006] Preferably, a dust removal section is provided between the cotton inlet and the vibrating plate.

[0007] Preferably, the vibrator is mounted on the back of the vibrating plate.

[0008] Preferably, the two vibrating plates are symmetrically arranged on both sides of the cotton box.

[0009] Preferably, the bottom of the two vibrating plates is provided with an opening, and the roller is located below the opening.

[0010] Preferably, the vibrator is an eccentric vibration motor.

[0011] The beneficial effects of this utility model are as follows: By setting up a vibrating plate, the vibrator on the vibrating plate can work as a regular cotton box when it is not activated; when the vibrator is activated, the vibrating plate will generate vibration at a corresponding frequency. The higher the vibration frequency, the more fibers fall on the roller below, and the greater the fiber density. By controlling the vibration frequency of the vibrator, the density of the final cotton box can be controlled, ensuring the uniformity of fiber distribution and improving product quality.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0016] See Figure 1 , Figure 2 A final cotton box density control device includes a cotton box 1. The cotton box 1 is provided with a cotton inlet 2, a vibrating plate 4, a roller 5, a beater 6 and a cotton outlet 7 from top to bottom. The vibrating plate 4 is located on both sides of the cotton box 1. The inner wall of the cotton box 1 is provided with a mounting frame. The top of the vibrating plate 4 rotates on the mounting frame. The bottom of the vibrating plate 4 is inclined downward towards the roller 5. The vibrating plate 4 is connected to the cotton box 1 by a spring 8. A vibrator 9 is installed on the vibrating plate 4.

[0017] A dust removal section 3 is provided between the cotton inlet 2 and the vibrating plate 4.

[0018] The vibrator 9 is mounted on the back of the vibrating plate 4.

[0019] Two vibrating plates 4 are symmetrically arranged on both sides of the cotton box 1.

[0020] The vibrator 9 is an eccentric vibration motor.

[0021] The fibers enter the final cotton box through the cotton inlet via a fan, and the air is discharged from the dust removal section. The fibers are stored in the cotton box. When the eccentric vibration motor is not started, the cotton box is a conventional cotton box, and the fiber density cannot be controlled.

[0022] When the eccentric vibration motor starts, the vibrating plate vibrates at a corresponding frequency; by adjusting the speed of the eccentric vibration motor, the vibrating plate will vibrate at different frequencies.

[0023] The higher the vibration frequency of the vibrating plate, the more fibers fall onto the roller, and the higher the fiber density; the lower the vibration frequency of the vibrating plate, the fewer fibers fall onto the roller, and the lower the fiber density. This achieves the goal of controllable density in the final cotton box. The fibers fall evenly onto the roller and are eventually held by the roller. After being loosened by the beater, they are sucked away by the fan at the cotton outlet to enter the next process.

[0024] This final cotton box density control device has a simple structure and is easy to install. It makes the pressure of the air pressure cotton box more uniform, achieves effective control of fiber density, provides a stable fiber supply for the next process, makes production more stable, and produces more uniform CD-MD products.

[0025] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
