Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production equipment, in particular to a needle punching machine. Background Art

[0002] The needle punching machine is a key equipment for producing needle punched non-woven fabrics. The patent with application number 201610780343.3 discloses a double-sided needle punching machine for non-woven fabrics, which includes a power unit, a conveying curtain, a needle punching unit and an output unit arranged in sequence according to the forward direction of the non-woven fabric; the needle punching unit includes a needle bed, a lower needle punch fixedly arranged on the lower end surface of the needle bed, a lower stripping screen fixedly arranged below the lower needle punching unit and a lower drag screen fixedly arranged below the lower stripping screen; the needle bed is fixedly connected to the power unit; the output unit includes an output roller driven by a motor, and the needle punching unit also includes a needle punch fixedly arranged on the upper end surface of the needle bed, an upper stripping screen fixedly arranged above the upper needle punching unit and an upper drag screen fixedly arranged above the upper stripping screen. It can needle punch the non-woven fabric twice as needed, with high efficiency and small footprint. However, it can only needle punch from one side of the non-woven fabric (front needle punching), but not from the other side (back needle punching). If the other side needs to be needle punched, the non-woven fabric needs to be turned over and the other side needs to be needle punched, which increases the process. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a needle loom for the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a needling machine, including a frame, on which two mesh plate groups arranged up and down are arranged, wherein an output roller group is arranged on one side of the lower mesh plate group, and a steering roller group is arranged on the side of the output roller group away from the mesh plate group, and two needling parts are also slidably connected to the frame, and the two needling parts are fixedly connected. The two needling parts are respectively located above the two mesh plate groups, and the needling parts include a needle bed and a plurality of non-woven needles arranged on the bottom surface of the needle bed. The upper part of the frame is also rotatably connected to a crankshaft driven by a power device, and the two ends of the connecting rod are respectively rotatably connected to the crankshaft and the needling part.

[0005] To further optimize the technical solution, a vertical guide bar is provided on the inner side of the frame, guide grooves are provided on both sides of the needle bed of the acupuncture part, and the guide bar is slidably connected to the guide groove.

[0006] To further optimize the technical solution, the two needling parts are connected together by connecting columns arranged at the four corners of the two parts.

[0007] Compared with the prior art, the utility model has the following advantages: two mesh plate groups are provided, and the non-woven fabric passes through one mesh plate group through a turning roller group and then out of the other mesh plate group, so that the two upward sides of the non-woven fabric in the two mesh plate groups are the front and back sides thereof, respectively, and the crankshaft drives the two needling parts to needle downward synchronously, so that needling can be performed from both the front and back sides of the non-woven fabric at the same time, saving the process. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 The present invention is a schematic diagram of the structure of a needling machine.

[0009] In the figure: 1, frame; 11, guide bar; 2, connecting rod; 3, crankshaft; 4, needling part; 5, steering roller group; 6, output roller group; 7, mesh plate group; 8, non-woven fabric; 9, connecting column. DETAILED DESCRIPTION

[0010] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0011] Specific implementation method: Combination Figure 1 As shown, a needle loom comprises a frame 1, on which two mesh plate groups 7 arranged in an upper and lower manner are arranged, the mesh plate group 7 comprises a mesh stripping plate and a mesh supporting plate, wherein an output roller group 6 is arranged on one side of the lower mesh plate group 7, and a steering roller group 5 is arranged on the side of the output roller group 6 away from the mesh plate group 7, and two needling parts 4 are also slidably connected to the frame 1, the needling part 4 comprises a needle bed, and a plurality of non-woven needles are arranged on the bottom surface of the needle bed, and the two needling parts 4 are fixedly connected, and the two needling parts 4 are respectively located above the two mesh plate groups 7, and the mesh stripping plate is located above the mesh supporting plate, and the upper part of the frame 1 is also rotatably connected to a crankshaft 3 driven by a power device, and the power device is a motor and a reducer, and the two ends of the connecting rod 2 are respectively rotatably connected to the crankshaft 3 and the needling part 4. The crankshaft 3 rotates, which can drive the two needling parts 4 to move up and down synchronously, and the two needling parts 4 can perform needling from the front and back sides of the non-woven fabric 8 respectively.
