[0003] For example, Chinese patent CN212357478U discloses a protective device for a carding machine for producing medical absorbent cotton balls, which includes a base plate and a protective mechanism. A carding machine body is installed in the middle of the top surface of the base plate, a first lifting mechanism is installed horizontally symmetrically with respect to the carding machine body on the left side of the top surface of the base plate, two groups of first lifting mechanisms are installed with a first truss on one side of the top, and one side of the bottom of the first truss is fixedly connected to the left side of the top of the protective mechanism, a second lifting mechanism is installed horizontally symmetrically with respect to the carding machine body on the right side of the top surface of the base plate, two groups of second lifting mechanisms are installed with a second truss on one side of the top, and one side of the bottom of the second truss is fixedly connected to the right side of the top of the protective mechanism.

[0004] However, in the prior art, the working principle of the cotton carding machine is to open, comb and remove impurities from the cotton rolls, fiber rolls or oil cotton layers sent from the previous process, so that all the curled cotton loops become basically straight single fibers, and in this process, the broken seeds, impurities and short fibers left over from the cotton cleaning process are removed, and then cotton strips of a certain specification are integrated and stored in cotton drums. During the rotation and winding of the cotton drum, if the single-fiber integrated cotton strips are collided by external forces, the cotton strips will become fluffy and rough, and in severe cases, the cotton strips will break, affecting the quality of the cotton strips and resulting in poor quality of the produced medical absorbent cotton balls. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that during the rotation and winding process of the cotton drum, if the cotton strips integrated with single fibers are collided by external forces, the cotton strips will become fuzzy and rough, and in severe cases, the cotton strips will be broken, thereby affecting the quality of the cotton strips and resulting in poor quality of the produced medical cotton balls. A protective device for a cotton carding machine for the production of medical cotton balls is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a protective device for a carding machine for producing medical absorbent cotton balls, comprising a mounting arm, one end of the mounting arm is fixedly connected to a protective mechanism, the protective mechanism comprises a fixed protective assembly and a movable protective assembly, the movable protective assembly is located on the outside of the fixed protective assembly, the fixed protective assembly comprises a fixed frame, both ends of the fixed frame are fixedly connected to a fan-shaped plate, the upper side of the fan-shaped plate is fixedly connected to an arc plate, the upper side of the arc plate is fixedly connected to a fan ring, the movable protective assembly comprises a movable frame, both ends of the movable frame are fixedly connected to a side plate, the other side of the side plate is fixedly connected to a mounting plate, and the other side of the mounting plate is rotatably connected to multiple groups of first roller groups and multiple groups of second roller groups.

[0007] Preferably, multiple groups of the first roller groups are respectively located on the inner and outer sides of the arc plate, and multiple groups of the second roller groups are respectively located on both sides of the fan-shaped plate.

[0008] Preferably, a connecting radian plate is fixedly connected to the outer side of the side plate, and reinforcement members are provided on the outer side of the connecting radian plate and the outer side of the side plate.

[0009] Preferably, built-in blocks are welded on both sides of the sector plate, and the built-in blocks are located on the inner side of the arc plate.

[0010] Preferably, one side of the built-in block is fixedly connected to an outer column shell, and the inner wall of the outer column shell is fixedly connected to a spring.

[0011] Preferably, the inner side of the outer column shell is slidably connected to the inner column shell, and the top of the inner cavity of the inner column shell is fixedly connected to the other end of the spring.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, multiple groups of first roller groups roll on the inner side of the arc plate and multiple groups of second roller groups roll on both sides of the fan ring, so that the movable frame extends from the fixed protection component along the arc trajectory of the arc plate, and the fixed frame and the movable frame cover the outer side of the cotton cylinder to protect the rotating cotton cylinder, avoid the external environment from directly contacting the single fiber integrated cotton strips, protect the cotton strips from external influences, and thus ensure the production quality of medical absorbent cotton balls.

[0014] 2. In the utility model, when the movable protective assembly rotates to the end of the arc plate along the arc trajectory, the first roller group directly hits the inner column shell, so that the inner column shell is forced to slide and shrink in the inner wall of the outer column shell, thereby compressing the spring to deform it and generate elastic force. The elastic force causes the inner column shell to push the first roller group back, so that the movable protective assembly is stuck on the fixed protective assembly and fully unfolded, while reducing the impact force and vibration of the movable protective assembly when unfolding along the arc, ensuring the stable unfolding of the movable protective assembly.

[0024] The following is a detailed description of the specific settings and functions of this embodiment: an arc shell is formed by two groups of side panels 422, a group of connecting arc plates 423 and a plurality of reinforcement members 424, which are distributed at both ends of the movable frame 421. In the initial state, the movable protection component 42 covers the outer side of the fixed protection component 41. After the cotton combing machine body 1 is powered on, the operator pulls the movable frame 421, thereby pulling the side panels 422, the connecting arc plates 423 and the mounting plate 425 to make an arc motion, thereby driving multiple groups of first roller groups 426 to roll on the inner side of the arc plate 412 and driving multiple groups of second roller groups 427 to roll on both sides of the fan ring 413. As a result, the movable frame 421 extends from the fixed protection component 41 along the arc trajectory of the arc plate 412, and the fixed frame 414 and the movable frame 421 cover the outer side of the cotton tube 2 to protect the rotating cotton tube 2, prevent the external environment from directly touching the single-fiber integrated cotton strips, protect the cotton strips from external influences, and thus ensure the production quality of medical absorbent cotton balls.
