Description

A precision feeding device for a multi-compartment cotton blending machine Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a precision feeding device for a multi-compartment cotton blending machine. Background Technology

[0002] A cotton blending machine is primarily used for opening and mixing cotton, facilitating the loosening and blending of raw materials and enabling subsequent production processes. This benefits cotton processing and production. In the textile industry, multi-compartment cotton blending machines are crucial for achieving uniform cotton mixing. The accuracy of the feed is paramount to the quality of the blend, directly impacting the quality of subsequent textile products.

[0003] Traditional multi-compartment cotton blending machine feeding devices have shortcomings in terms of feeding accuracy control, making it difficult to meet the increasingly demanding requirements of textile processes. For example, overfeeding or underfeeding may occur, leading to inaccurate blending ratios and affecting the quality stability of the final product. Therefore, we propose a precision feeding device for multi-compartment cotton blending machines to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a precision feeding device for a multi-compartment cotton blending machine. It can accurately control the feeding weight through the cooperation of a weighing device and a stepper motor, and automatically open the feeding hole through a linkage structure such as a push rod motor. The sealing design prevents cotton leakage, thereby achieving precise feeding, improving the degree of automation, and ensuring the normal operation of the device and the cleanliness of the environment.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a precision feeding device for a multi-compartment cotton blending machine, comprising a cotton storage box, two weighing devices fixedly installed at the bottom of the cotton storage box, a common weighing plate installed on the top of the two weighing devices, a frame plate fixedly installed on the top of the weighing plate, a discharge hole opened at the bottom of the weighing plate, a feeding pipe fixedly installed at the bottom of the weighing plate, the feeding pipe penetrating the cotton storage box, a receiving groove opened on both sides of the inner wall of the discharge hole, a baffle slidably installed in the receiving groove, and the baffle is adapted to the discharge hole, a partition is installed on the inner wall of the receiving groove, and multiple return springs are fixedly installed on one side of the partition, and one end of the return spring is fixedly installed on the corresponding baffle.

[0006] By adopting the above technical solution, the feeding weight can be precisely controlled by the combination of a weighing device and a stepper motor. The feeding hole can be automatically opened by the linkage structure such as the push rod motor. The sealing design prevents cotton leakage, thereby achieving precise feeding, improving the degree of automation, and ensuring the normal operation of the device and the cleanliness of the environment.

[0007] A further feature of this invention is that: both sides of the inner wall of the cotton storage box are provided with connecting holes, and the frame plate is provided with a pushing mechanism for pushing cotton. The pushing mechanism includes a push rod motor and a push plate. Both sides of the frame plate are fixedly installed with push rod motors, which pass through the corresponding connecting holes. The output shaft of the push rod motor extends into the frame plate and is fixedly installed with a push plate.

[0008] By adopting the above technical solution, the push rod motors and push plates symmetrically arranged on both sides can efficiently push the weighed cotton in the frame plate to the feeding hole from different directions, which greatly improves the efficiency and uniformity of feeding.

[0009] A further feature of this invention is that: grooves are provided on both inner walls of the frame plate; a guide rod is fixedly installed on the front and rear inner walls of the grooves; a pulling mechanism is provided between the push plate and the corresponding baffle; the pulling mechanism includes a guide rod and a connecting rope; the guide rod is fixedly installed on the front and rear inner walls of the storage groove; a connecting rope is fixedly installed on one side of the baffle; one end of the connecting rope passes around the guide rod and the guide rod and is fixedly installed on the push plate.

[0010] By adopting the above technical solution, the linear motion of the pusher plate is cleverly transformed into the sliding motion of the baffle by using the connecting rope of guide rod one and guide rod two. This makes the pushing and opening of the feeding hole synchronized, avoids human operation errors, and improves the accuracy of feeding control.

[0011] A further feature of this invention is that: a guide hopper is installed inside the cotton storage box, and a cotton conveying assembly is provided inside the guide hopper; a rotating shaft is rotatably installed on the front and rear inner walls of the guide hopper; a conveying roller is fixedly installed on the rotating shaft; multiple baffles are installed at equal intervals on the outer side of the conveying pipe; and a stepper motor is fixedly installed on the rear side of the cotton storage box, with the output shaft of the stepper motor extending into the guide hopper and fixedly connected to the rotating shaft.

[0012] By adopting the above technical solution, the stepper motor drives the rotating shaft to rotate the conveying roller and the deflector plate, which can stably and continuously convey the cotton at the top of the cotton storage box to the weighing plate in a quantitative manner, ensuring the continuity and stability of the feeding process.

[0013] A further feature of this invention is that a controller is fixedly installed on the front side of the cotton storage box, and the weighing device, push rod motor and stepper motor are all electrically connected to the controller.

[0014] By adopting the above technical solution, the controller coordinates the operation of each component and precisely controls the stepper motor feeding and push rod motor pushing based on the feedback from the weighing device, thereby achieving automated and intelligent precise feeding control.

[0015] A further feature of this invention is that a sealing groove is provided on the inner wall of the storage slot, a sealing strip is installed in the sealing groove, and the baffle and the sealing strip are slidably and sealingly connected.

[0016] By adopting the above technical solution, the sealing strip and the sealing groove fit tightly together, effectively preventing cotton from leaking from the gaps around the feed hole during storage and feeding, maintaining the cleanliness of the equipment interior, and ensuring the long-term stable operation of the feeding device.

[0017] The beneficial effects of this utility model are:

[0018] (1) The controller can drive the stepper motor, which can drive the rotating shaft to rotate. The rotating shaft can drive the conveying roller and the deflector to rotate. The rotation of the deflector can convey the cotton above the guide hopper to the weighing plate. The weigher can weigh the cotton on the weighing plate 103. When the specified weight is reached, the controller can turn off the stepper motor to stop feeding, thus facilitating the accurate feeding of cotton.

[0019] (2) The push rod motor can be started by the controller. The push rod motor can move the push plate towards the downward material hole. The push plate can push the cotton towards the downward material hole. The movement of the push plate can pull the baffle to move through the connecting rope. The baffle can compress the reset spring and be stored in the storage groove, thereby opening the feeding hole so that the cotton on the weighing plate can enter the feeding pipe through the feeding hole and achieve the purpose of accurate feeding.
