Description

Technical Field

[0001] This utility model belongs to the field of safety cover technology, specifically relating to a safety cover for a combing machine. Background Technology

[0002] The main function of a carding machine is to loosen messy fibers into relatively straight single fibers, remove impurities, and mix fibers of different colors or qualities. In roving, carding machines are usually composed of two- or three-roller carding machines to produce roving for spinning machines. In combed wool, carding machines are generally composed of two roller carding machines connected directly without passing through a bridge machine. The output wool web is collected into wool slivers for subsequent manufacturing of combed wool slivers.

[0003] The working principle of a carding machine is mainly to separate impurities and short fibers from the raw material through a series of rotation and combing actions, ultimately obtaining pure and uniform fibers.

[0004] However, in the current use of carding machines, some high-speed rotating parts are exposed without the necessary protective covers, which can easily cause danger during production. In addition, the lack of protection makes the parts susceptible to damage from the external environment, affecting the service life of the carding machine. Therefore, a safety cover for carding machines is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a safety cover for a combing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety cover for a combing machine, which is applied to a combing machine. Two sliding rods are fixedly installed on the combing machine, and a sliding block is slidably provided on the outside of the two sliding rods. A safety cover is rotatably connected to the sliding block. A permanent magnet is fixedly installed on the combing machine, and the metal surface at the bottom of the safety cover is magnetically attracted to the permanent magnet.

[0007] The safety cover can be rotated to cover and protect the combing machine or opened, and can also be easily disassembled and installed from an oblique top by sliding on the sliding rod.

[0008] In a preferred embodiment, the sliding block is rotatably connected to two rotating slip rings, and the sliding block is slidably connected to two sliding rods through the two rotating slip rings.

[0009] In a preferred embodiment, each of the sliding rods is provided with friction patterns on one side thereof, and the friction patterns are arranged at an angle;

[0010] By setting the friction grooves at an angle, the sliding of the rotating slip ring on the sliding rod is restricted in one direction.

[0011] In a preferred embodiment, each of the rotating slip rings is fixedly connected with an arc-shaped friction block;

[0012] The friction block can increase the contact friction with the friction pattern when the rotating slip ring slides, thereby positioning the sliding block at a certain position on the sliding rod.

[0013] In a preferred embodiment, a connecting block is fixedly installed on one side of each of the rotating slip rings, and a synchronizing rod for synchronous operation is rotatably connected to both connecting blocks.

[0014] In a preferred embodiment, the synchronizing rod is provided with a space frame to accommodate its synchronized operation.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model's safety cover can rotate to cover the combing machine, enclosing the previously exposed high-speed rotating parts and preventing accidental contact by operators, thus reducing danger. At the same time, it provides protection for the parts, reduces the impact of the external environment, and extends the service life of the combing machine. Moreover, the safety cover can slide on a sliding rod, making it easy to disassemble and install from an oblique top. During equipment operation, cleaning, and maintenance, there is no need for cumbersome disassembly of fixed parts, improving operational convenience and maintenance efficiency.

[0017] This utility model features an obliquely arranged friction pattern that cooperates with the arc-shaped friction block inside the rotating slip ring. Combined with the magnetic attraction of the permanent magnet block to the obliquely upward metal surface of the safety cover, the safety cover on the sliding block can be positioned at a certain location on the sliding rod without hindering further upward sliding adjustment. This allows the safety cover to provide varying degrees of coverage for the combing machine according to actual needs. For example, it can completely cover the machine during normal operation to protect high-speed rotating components; or it can be opened appropriately during simple inspections to facilitate observation of the machine's operation.

[0018] When operating the synchronizing rod, the connecting block can drive the rotating slip ring to rotate, causing the friction block to rotate to the friction-free side of the sliding rod, thereby releasing the unidirectional sliding restriction of the sliding block on the sliding rod, facilitating flexible and stable adjustment and operation of the safety cover.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0029] Please see Figure 1-7 This utility model provides a safety cover for a combing machine, which is applied to a combing machine 1. Two sliding rods 2 are fixedly installed on the combing machine 1. A sliding block 3 is slidably arranged on the outside of the two sliding rods 2. A safety cover 4 is rotatably connected to the sliding block 3. A permanent magnet block 5 is fixedly installed on the combing machine 1. The metal surface 6 at the bottom of the safety cover 4 is magnetically attracted to the permanent magnet block 5. The safety cover 4 can cover and protect the combing machine 1 or open it by rotating. It can also be easily disassembled and installed from an oblique top by sliding on the sliding rods 2.

[0030] The sliding block 3 is rotatably connected to two rotating slip rings 7, and the sliding block 3 is slidably connected to the two sliding rods 2 through the two rotating slip rings 7.

[0031] Each sliding rod 2 has a friction pattern 8 on one side. The friction pattern 8 is set at an angle, which restricts the unidirectional sliding of the rotating slip ring 7 on the sliding rod 2.

[0032] Each rotating slip ring 7 has an arc-shaped friction block 9 fixedly connected inside. When the rotating slip ring 7 slides, the friction block 9 can increase the contact friction with the friction pattern 8, so as to realize the positioning of the sliding block 3 at a certain position on the sliding rod 2.

[0033] Each rotating slip ring 7 has a connecting block 10 fixedly installed on one side, and a synchronizing rod 11 for synchronous operation is rotatably connected to both connecting blocks 10.

[0034] The synchronizing rod 11 is provided with a space frame 12 to accommodate its synchronous operation.

[0035] The working principle and usage process of this utility model are as follows: First, the safety cover 4 can slide above the combing machine 1 through the cooperation of the rotating slip ring 7 and the sliding rod 2. When it is necessary to cover and protect the combing machine 1, the safety cover 4 is slid to a suitable position. At this time, the metal surface 6 at the bottom of the safety cover 4 is fixed under the magnetic attraction of the permanent magnet block 5. At the same time, the friction block 9 in the rotating slip ring 7 interacts with the oblique friction texture 8 on the sliding rod 2 to further realize the positioning of the sliding block 3, prevent the safety cover 4 from sliding at will, and ensure effective protection of high-speed rotating parts. When performing inspection or maintenance operations, the synchronous rod 11 can be operated. At this time, the space frame 12 can cover the sliding rod 2 on one side when rotating synchronously, so as to prevent the sliding rod 2 from obstructing the rotation of the rotating slip ring 7 on one side. The rotating slip ring 7 is driven to rotate through the connecting block 10, so that the friction block 9 leaves the side where the friction texture 8 is located, and the sliding restriction is released. The safety cover 4 can be opened by sliding obliquely upwards, which can be opened by rotation, so that the operator can easily observe the operation of the equipment or perform cleaning and maintenance.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
