[0013] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0014] Embodiment 1:
[0015] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model discloses a dust suction device for a circular knitting machine, comprising an annular body 1, the interior of the annular body 1 is a hollow structure, a dust suction port 4 is arranged on the inner wall of the annular body 1, the dust suction port 4 is connected with the hollow structure, a dust suction pipe 5 is arranged on the annular body 1, the dust suction pipe 5 is connected with a negative pressure device, at least three support bodies are arranged at the lower end of the annular body 1, the support bodies are evenly spaced and connected to the lower end of the annular body 1, the support bodies are electric push rods 3, and all the electric push rods 3 move synchronously.
[0016] An annular body 1 is arranged on the periphery above the knitting needles of the circular knitting machine. The annular body 1 can be arranged by an electric push rod 3. Of course, the electric push rod 3 can be fixed to the ground directly or fixed to the ground through a frame according to actual needs. The electric push rod 3 can be raised and lowered to realize the lifting and lowering movement of the entire annular body 1 to meet different dust collection requirements. All electric push rods 3 move synchronously, so the annular body 1 is lifted and lowered as a whole, and there is no interference between the electric push rods 3, which has high stability. The hollow structure inside the annular body 1 is connected to the negative pressure device through the dust suction pipe 5, and the negative pressure device is similar to a vacuum cleaner, which can generate negative pressure in the hollow structure and collect the sucked short fibers and the like.
[0017] Through the continuous vacuuming of the vacuum port 4 on the annular body 1, lint, short fibers, etc. will not accumulate, so only a relatively small negative pressure is required, which will not cause fluctuations in the delivery of the yarn, thereby improving the stability of the yarn entering the circular knitting machine.
[0018] The annular body 1 is formed by splicing eight arc-shaped bodies 2, wherein each arc-shaped body 2 is a one-eighth arc-shaped structure, each arc-shaped body 2 is a hollow structure, each arc-shaped body 2 is provided with a dust suction pipe 5, and the dust suction pipe 5 is connected to the hollow structure, and a connecting hole is provided at one end of each arc-shaped body 2, and the support body is four, and two arc-shaped bodies 2 are sleeved on each support body to form a quarter arc-shaped structure, and the arc-shaped bodies 2 on the four support bodies form a circular structure. The annular body 1 is formed by splicing eight arc-shaped bodies 2, and the arc-shaped bodies 2 are respectively arranged on the support body, that is, on the electric push rod 3, and the arc-shaped body 2 and the support body can rotate relative to each other. Therefore, when the worker operates the circular machine, the arc-shaped body 2 of the corresponding part can be rotated to the outside to expose the circular machine of the part to the outside, and the operation of the circular machine is also more convenient. The annular body 1 will take up space, which improves the convenience of operation. After the operation is completed, the arc-shaped body 2 is reset to make it close to the circular machine, thereby improving the dust collection effect.
[0019] The ends of two adjacent arc-shaped bodies 2 on two adjacent supporting bodies are respectively provided with a concave structure 6 and a convex structure 7, which are all distributed in the radial direction of the arc-shaped body 2, and the convex structure 7 on the arc-shaped body 2 is engaged with the concave structure 6 on another adjacent arc-shaped body 2. In order to prevent the arc-shaped body 2 from moving during normal vacuuming, the concave structure 6 and the convex structure 7 are arranged between the arc-shaped bodies 2. When the eight arc-shaped bodies 2 cooperate to form the annular body 1, the concave structure 6 of the arc-shaped body 2 cooperates with the convex structure 7 to connect, so that the two will not move at will and always maintain an annular shape, so as to improve the vacuuming effect and vacuuming stability.
[0020] A through hole 8 is arranged inside the protruding structure 7, two steel balls 10 are arranged in the through hole 8, a compression spring 9 is arranged in the through hole 8 between the steel balls 10, the diameters of the two ends of the through hole 8 gradually decrease, and the steel balls 10 are partially exposed to the outside of the through hole 8, and recessed holes 11 are arranged on the inner walls on both sides of the recessed structure 6 corresponding to the through hole 8. In a natural state, the steel balls 10 exposed to the outside of the through hole 8 are located in the recessed holes 11.
[0021] The steel ball 10 is placed at both ends of the through hole 8 by using a compression spring 9, and the steel ball 10 is partially exposed to the outside of the through hole 8, so that when the two arc-shaped bodies 2 are matched, the inner concave structure 6 of the arc-shaped body 2 is clamped on the outside of the convex structure 7, and during the matching process, the steel ball 10 is compressed into the through hole 8 until the through hole 8 corresponds to the concave hole 11, and the steel ball 10 is squeezed by the compression spring 9 and partially enters the through hole 8, thereby realizing the matching connection between the two arc-shaped bodies 2. During normal operation, even if the circular knitting machine has a certain vibration, the arc-shaped bodies 2 can be stably connected. When it is necessary to remove the arc-shaped body 2, the operator can apply external force to rotate the arc-shaped body 2, and the steel ball 10 will be pressed into the through hole 8 to achieve the separation between the arc-shaped bodies 2.
[0022] The above structure can make the connection between the arc-shaped bodies 2 more stable and the operation is simple and convenient.
