[0021] Embodiment 1

[0022] See also Figure 1 to Figure 2 , which is a schematic diagram of a positioning and cleaning mechanism for a shaping machine needle plate 33 and a shaping machine provided by the utility model. The positioning and cleaning mechanism for the shaping machine needle plate 33 includes a frame 10; a conveyor chain 20, a positioning mechanism 30, a cleaning wheel 40 and other structures arranged on the frame 10. It can be imagined that the positioning and cleaning mechanism for the shaping machine needle plate 33 also includes other functional components and specific structures, such as electrical connection components, mounting structures, etc., which are all well-known technologies to those skilled in the art, so they will not be described in detail one by one here.

[0023] The rack 10 is set on the ground or on an equipment platform, and the machine installation position has a height difference from the ground.

[0024] The conveyor chain 20 is arranged in a circular direction on one side of the frame 10. In this embodiment, the main body of the conveyor chain 20 includes two parallel horizontal chains, and the two ends of the two horizontal chains are respectively connected by arc chains to form a circular conveying structure, and the upper end of the conveyor chain 20 is circularly conveyed along the horizontal direction of the frame 10. The conveyor chain 20 is meshed through a gear shaft, and the gear shaft is connected to a driving motor to complete power transmission.

[0025] The positioning mechanism 30 includes a conveying block 31 which is connected to the conveying chain 20 at intervals and protrudes from one side of the frame 10 at one end. The conveying block 31 moves synchronously with the conveying chain 20, and there is a gap between the conveying blocks 31 to increase the size of the gap for the dust to fall. The end of the conveying block 31 away from the frame 10 is provided with a mounting portion 32 extending toward the inner side of the conveying chain 20, and a needle plate 33 is provided on the mounting portion 32, which is vertically facing outward along the conveying chain 20; when the needle plate 33 pierces the edge of the cloth, the edge of the cloth is laid flat on the needle plate 33. There is a height difference between the mounting portion 32 and the conveying block 31 to prevent the cloth from being rolled into the conveying chain 20, while reducing the amount of dust falling on the surface of the conveying block 31 or even in the conveying chain 20.

[0026] Both ends of the needle plates 33 protrude in the width direction of the mounting portion 32 , thereby reducing the spacing between the needle plates 33 and increasing the fabric laying effect between the suspended needle plates 33 .

[0027] The cleaning wheel 40 is rotatably arranged on the frame 10 and is located above the needle plate 33. The circumferential outer wall of the cleaning wheel 40 is provided with bristles 41 which are arranged circumferentially and can be connected with the needle plate 33. The cleaning wheel 40 is connected to a rotary motor drive, and the cleaning wheel 40 drives the bristles 41 to contact the needle plate 33 and the edge of the cloth to remove the dust on the cloth and the upper end of the needle plate 33. It is conceivable that an unpowered cleaning wheel 40 can also be used, and the bristles 41 are connected to the needle plate 33 to achieve the purpose of driving the cleaning wheel 40 to rotate and complete the cleaning of the bristles 41. The height of the needle plate 33 is lower than the height of the conveying block 31, that is, the contact point between the bristles 41 and the needle plate 33 is lower than the conveying block 31, ensuring that the cleaned dust is not easy to rise to the surface of the conveying block 31.

[0028] An inclined section 34 is provided between the mounting portion 32 and the conveying block 31 . The inclined section 34 increases the horizontal extension distance of the mounting portion 32 , blocks the dust from floating in the horizontal direction and facilitates the dust from sliding down into the dust trough 35 .

[0029] A concave dust groove 35 is provided between the inclined section 34 and the needle plate 33. The dust groove 35 is conducive to collecting the dust that does not fall from the gap, so as to facilitate subsequent dust suction and cleaning.

[0030] The widths of the conveying block 31, the inclined section 34 and the mounting portion 32 are successively increased in a step-like manner toward the outside, thereby increasing the size of the gap through which the feeding dust falls and reducing interference between the components.

[0031] A dust suction pipe 50 is provided on the frame 10 and at the rear end of the cleaning wheel 40. The dust suction pipe 50 is connected to an air pump to realize the function of suction or blowing of the dust suction pipe 50. When the dust suction pipe 50 is used for suction, there is a negative pressure in the dust suction pipe 50. Generally, the dust suction port 51 of the dust suction pipe 50 is set above the needle plate 33. When the needle plate 33 passes, it is convenient to suck up the dust on the edge of the cloth and in the dust groove 35, and collect it into the dust tank through the dust suction pipe 50.

[0032] The frame 10 is provided with elastic clips 52 which are arranged at intervals and for the dust suction tube 50 to be clamped. The dust suction tube 50 is a hose structure. The elastic clips 52 are used to fix the position of the dust suction tube 50 and the dust suction port 51. In the shutdown state, the dust suction tube 50 under the elastic clips 52 can be taken out, and the mobility of the dust suction tube 50 can be used to complete the overall dust suction or blowing maintenance.

[0034] The utility model also provides a shaping machine, which has the shaping machine needle plate 33 positioning and cleaning mechanism as described above. Except for the shaping machine needle plate 33 positioning and cleaning mechanism, other components are all existing technologies or commercially available parts.

[0035] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
