DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, an online material detection device comprises: two conveyor frames 1 and a conveyor belt 2, wherein the two conveyor frames 1 are installed on both sides of the conveyor belt 2; a detection mechanism 3, wherein the detection mechanism 3 is installed between the two conveyor frames 1, and the lower end of the detection mechanism 3 extends to the lower side of the conveyor belt 2; wherein the detection mechanism 3 comprises a pressing platform 31 fixedly connected to the side of the conveyor frame 1 close to the conveyor belt 2, wherein the inner wall of the pressing platform 31 is rotatably connected to a plurality of rollers 311, wherein the lower end of the roller 311 is provided with a pressing component 32, and one end of the pressing component 32 is provided with a detection component 33;

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the abutting assembly 32 includes a middle shaft 321 fixedly connected between the two conveying frames 1, the middle shaft 321 is located below the conveyor belt 2, the surface of the middle shaft 321 is rotatably connected to the bottom frame 322, the end of the bottom frame 322 is fixedly connected to a connecting plate 323, the upper end of the connecting plate 323 is fixedly connected to a guide rod 324, the abutting assembly 32 includes a cross baffle 325 fixedly connected between the two conveying frames 1, the upper end of the cross baffle 325 is provided with a slot, the upper end of the guide rod 324 passes through the slot, the surface of the guide rod 324 is sleeved with a bottom spring 326, the upper and lower ends of the bottom spring 326 are respectively fixedly connected to the lower end of the cross baffle 325 and the upper end of the connecting plate 323. The device can keep the connection plate 323 downward by the elastic potential energy of the bottom spring 326, and the guide rod 324 can guide the bottom spring 326, so that the connection plate 323 keeps the tendency to move downward under normal conditions, and then the bottom frame 322 is kept positioned on the middle axis 321, so that the end of the bottom frame 322 close to the detection component 33 is always in an upward movement state. When a formed tray moves to the top of the detection component 33 through the conveyor belt 2, the detection component 33 starts to move downward due to the tray, and starts to detect the tray.

[0026] like Figure 2 , Figure 4 and Figure 5 As shown, the detection assembly 33 includes a fixed ring 331 installed at one end of the bottom frame 322, the inner wall of the fixed ring 331 is rotatably connected to a guide tube 332, the inner wall of the guide tube 332 is slidably connected to a sliding tube 333, the inner wall of the sliding tube 333 is threadedly connected to a threaded rod 334, a middle rotating seat 337 is fixedly connected between the two threaded rods 334, a coil spring 335 is fixedly connected to the surface of the guide tube 332, the other end of the coil spring 335 is fixedly connected to one side of the fixed ring 331, an articulated frame 336 is installed between the fixed ring 331 and the middle rotating seat 337, and an elastic ring 338 is sleeved on the surface of the articulated frame 336;

[0027] At this time, the tray contacts the elastic collar 338 during the transportation process, and then the elastic collar 338 drives the articulated frame 336 to rotate accordingly. At the same time, when the tray contacts the elastic collar 338, the articulated frame 336 is driven to rotate accordingly. At this time, the articulated frame 336 drives the guide tube 332 to rotate on the inner wall of the fixed ring 331 through the sliding tube 333. When the rotation is completed, the guide tube 332 is reset under the action of the coil spring 335. At this time, the rotation angle of the articulated frame 336 can be collected by the sensor. When the cut trays have different lengths, the rotation angle of the articulated frame 336 deviates, which is collected by the sensor to achieve the effect of detecting the tray.

[0028] At the same time, when the elastic ring 338 needs to be adjusted, the limit of the middle swivel seat 337 is released and it is rotated, wherein the guide tube 332 can play an auxiliary positioning effect under the action of the coil spring 335. At this time, the rotation of the middle swivel seat 337 drives the threaded rods 334 on both sides to rotate synchronously. At this time, the threaded rod 334 is adjusted under the action of the sliding tube 333, and the sliding tube 333 is located on the inner side of the guide tube 332.

[0029] When the utility model is in use, the formed pallet is transported following the conveyor belt 2. During the transportation, the pallet contacts the elastic ring 338, and the elastic ring 338 drives the articulated frame 336 to rotate accordingly. When the pallet contacts the elastic ring 338, the articulated frame 336 is driven to rotate accordingly. The articulated frame 336 drives the guide tube 332 to rotate on the inner wall of the fixed ring 331 through the sliding tube 333. After the rotation is completed, the guide tube 332 is reset under the action of the winding spring 335. The sensor is used to collect whether there is any deviation in the rotation angle of the articulated frame 336, so as to achieve the effect of detecting the pallet.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
