The hinged door 110 slides back and forth between the two non-linear guide rails 120 in the left-right direction or the front-back direction to open or close the inlet and outlet.

[0060] A door switch unit 200, which includes a synchronous belt mechanism 210 that drives a hinge door 110 to slide along two non-linear guide rails 120, and a driving mechanism 220 that drives the synchronous belt mechanism 210 to rotate.

[0061] In the embodiment of the present application, the two non-linear guide rails 120 are arranged at an upper and lower interval, and the shapes of the two non-linear guide rails 120 can be specifically set according to the shape of the detection production equipment and the size of the feeding and discharging port. The shape of the non-linear guide rail 120 can be set as an "L" shape, a "匚" shape or a "C" shape. In the embodiment of the present application, the non-linear guide rail 120 with an "L" shape structure is taken as an example for illustration. Among them, the non-linear guide rail 120 located at the upper end of the hinge door 110 is the upper non-linear guide rail 121, and the non-linear guide rail 120 located at the lower end of the hinge door 110 is the lower non-linear guide rail 122.

[0062] The automatic door opening and closing structure of the present application is provided with two mutually parallel non-linear guide rails 120, and the linear shapes of the two non-linear guide rails 120 can be specifically set according to the shape of the detection production equipment and the size of the feeding and discharging port. A hinge door 110 is slidably connected between the two non-linear guide rails 120. The shape of the hinge door 110 can be adaptively adjusted according to the linear shape of the non-linear guide rail 120. The hinge door 110 slides along the non-linear guide rail 120 to open or close the feeding and discharging port of the detection production equipment. When the hinge door 110 opens the feeding and discharging port, the hinge door 110 is hidden inside the shell of the detection production equipment, does not occupy the external space of the detection production equipment, and reduces the volume and floor area of the detection production equipment.

[0063] The automatic door opening and closing structure of the present application is provided with a door switch unit 200, which includes a synchronous belt mechanism 210 that drives a hinge door 110 to slide along a non-linear guide rail 120, and a driving mechanism 220 that drives the synchronous belt mechanism 210. The first synchronous belt 213 of the synchronous belt mechanism 210 is soft in texture, and can not only drive the hinge door 110 to open or close the feeding and discharging port, but also adaptively adjust its own shape according to the linear shape of the non-linear guide rail 120 to prevent jamming between the hinge door 110 and the non-linear guide rail 120.

The synchronous belt connector 150 includes a mounting plate 151 connected to the hinged door 110, a pressing plate 152 for clamping the first synchronous belt 213 is connected to the mounting plate 151; a slider is connected to the mounting plate 151, and a mounting plate guide rail 123 slidably connected to the slider is fixed to the upper non-linear guide rail 121.

[0080] The length direction of the mounting plate guide rail 123 is parallel to the length direction of the first synchronous belt 213, so that the mounting plate 151 slides along the direction of the mounting plate guide rail 123 and keeps consistent with the length direction of the first synchronous belt 213. A proximity sensor 160 is also connected to the mounting plate 151, and the proximity sensor 160 is connected to the reduction motor 223. When the hinged door 110 slides to the set position, the proximity sensor 160 controls the reduction motor 223 to stop, so as to prevent the hinged door 110 from continuing to slide and causing safety hazards.

[0081] The stopper 215 and the elastic member 216 are used to limit the travel range of the synchronous belt connector 150. When the synchronous belt connector 150 abuts against the elastic member 216, the hinged door 110 is restricted from sliding further. The synchronous belt connector 150 is connected to the hinged door 110 by means of the mounting plate 151, and the first synchronous belt 213 is fixed to the mounting plate 151 by means of the pressing plate 152. The mounting plate 151 is also connected to a proximity sensor 160. When the proximity sensor 160 is triggered, the reduction motor 223 is controlled to stop, so that the hinged door 110 stops sliding.

[0082] A second aspect of the embodiment of the present application provides a production device, including:

[0083] A production equipment shell is provided with an inlet and outlet, and the production equipment shell is connected with an automatic opening and closing door structure described in any of the above embodiments for opening or closing the inlet and outlet.

[0084] The upper non-linear guide rail 121 and the lower non-linear guide rail 122 are both connected with a guide rail mounting plate 124, which respectively fixes the upper non-linear guide rail 121 and the lower non-linear guide rail 122 to the production equipment housing and is respectively located at the upper and lower ends of the inlet and outlet. The bearing seat 218, the driven wheel mounting seat 214 and the motor mounting seat 224 of the door switch unit 200 are all fixed to the production equipment housing by bolts.

[0085] How it works

[0086] An embodiment of the present application provides an automatic opening and closing door structure and a production device thereof. Since the automatic opening and closing door structure of the present application is provided with a hinge door unit 100, the hinge door unit 100 includes non-linear guide rails 120 that are parallel to each other and spaced apart, and a hinge door 110 that is slidably connected to the non-linear guide rails 120; a door switch unit 200, the door switch unit 200 includes a synchronous belt mechanism 210 that drives the hinge door 110 to slide along the non-linear guide rails 120, and a driving mechanism 220 that drives the synchronous belt mechanism 210.

[0087] Therefore, the automatic door opening and closing structure of the present application is provided with two non-linear guide rails 120 parallel to each other, and the linear shape of the two non-linear guide rails 120 can be specifically set according to the shape of the detection production equipment and the size of the inlet and outlet. A hinged door 110 is slidably connected between the two non-linear guide rails 120, and the shape of the hinged door 110 can be adaptively adjusted according to the linear shape of the non-linear guide rails 120. The hinged door 110 slides along the non-linear guide rails 120 to open or close the inlet and outlet of the detection production equipment. When the hinged door 110 opens the inlet and outlet, the hinged door 110 is hidden in the outer shell of the detection production equipment, does not occupy the external space of the detection production equipment, and reduces the volume and floor space of the detection production equipment.

[0088] The automatic door opening and closing structure of the present application is provided with a door opening and closing unit 200, which includes a synchronous belt mechanism 210 that drives the hinged door 110 to slide along the non-linear guide rail 120, and a driving mechanism 220 that drives the synchronous belt mechanism 210. The synchronous belt of the synchronous belt mechanism 210 is soft in texture, which can not only drive the hinged door 110 to open or close the inlet and outlet, but also can adaptively adjust its own shape according to the linear shape of the non-linear guide rail 120 to prevent the hinged door 110 from getting stuck with the non-linear guide rail 120. The driving mechanism 220 can drive the synchronous belt mechanism 210 to rotate according to the control signal, realize the automatic opening or closing of the hinged door 110, and improve the automation level and detection efficiency of the detection production equipment.
