[0035] The present invention will be further described below with reference to the drawings.

[0036] Please refer to Figures 1 - 12 , an embodiment provided by the present invention: a circulating guiding type conveying device for food detection, including a conveying device 3 for supporting and conveying. Symmetrically fixed on the upper end face of the conveying device 3 are detection devices 1, and the two groups of detection devices 1 are fixedly connected by a transmission guide shaft 2. A driven pulley 10 is fixedly installed near the end of the upper end face of the conveying device 3. On the inner end face of the detection device 1 on one side, toothed pulleys 4 are symmetrically rotatably clamped, and the two groups of toothed pulleys 4 are meshed and connected by a toothed belt 8. A servo motor 7 is fixedly installed on the inner end face of the detection device 1 directly opposite to the toothed pulley 4 at the bottom, and a half gear 6 is fixedly installed at the center of the front end face of the servo motor 7. A driving pulley 5 is rotatably clamped near the middle of the front end face of the detection device 1, and the driving pulley 5 and the driven pulley 10 are meshed and connected by a connecting belt 9.

[0037] As Figure 6 , the detection device 1 includes a guiding device 11, a supporting device 12, a limiting chute 13, a supporting guide rail 14 and a limiting device 15. A guiding device 11 is rotatably clamped at the center of the inner end face of the supporting guide rail 14, and a limiting chute 13 is opened through the inner end face of the supporting guide rail 14 to the outside. A supporting device 12 is slidably clamped on the front end face of the supporting guide rail 14 through the guiding device 11, and a limiting device 15 is elastically slidably clamped on the inner end face of the supporting device 12.

[0038] As Figure 7 and Figure 8 , the guiding device 11 includes a connecting slide plate 111, an installation seat 112, a positioning rotating groove 113, a transmission turntable 114 and a connecting cam 115. Two groups of positioning rotating grooves 113 are opened on the inner end face of the installation seat 112, and a transmission turntable 114 is rotatably clamped near the end of the upper end face of the installation seat 112. A connecting cam 115 is fixedly installed at the center of the rear end face of the transmission turntable 114, and a connecting slide plate 111 is fixedly installed on the front end face of the transmission turntable 114.

[0039] As Figure 9 , the support device 12 includes a support bracket 121, a fixed slide plate 122, a limit block 123, and a fixed housing 124. A fixed slide plate 122 is fixedly installed at the center of the front end face of the support bracket 121, and a fixed housing 124 is fixedly provided at the top of the side end face of the support bracket 121. A limit block 123 is fixedly installed at the center of the inner end face of the fixed housing 124.

[0040] As Figure 10 , the limiting device 15 includes a limiting shaft 151, a support guide shaft 152, a spring guide ring 153, a limiting slide plate 154, and a mounting seat 155. A mounting seat 155 is fixedly installed at the bottom of the front end face of the limiting slide plate 154, and support guide shafts 152 are symmetrically and fixedly installed at the inner end face of the limiting slide plate 154. A spring guide ring 153 is fixedly installed at the position of the inner end face of the limiting slide plate 154 corresponding to the support guide shafts 152, and a limiting shaft 151 is fixedly installed near the rear of the side end face of the limiting slide plate 154.

[0041] As Figure 11 and Figure 12 , the conveying device 3 includes a protective baffle 31, a support frame 32, a limiting rotating shaft 33, a driving guide roller 34, a conveyor belt 35, a limiting groove 36, and a mounting groove 37. Protective baffles 31 for limiting are symmetrically and fixedly installed on the upper end face of the support frame 32, and mounting grooves 37 are symmetrically formed in the middle of the side end face of the support frame 32. Limiting rotating shafts 33 are symmetrically and rotatably clamped on the outer end face of the support frame 32, and driving guide rollers 34 are symmetrically and fixedly installed on the outer end face of the limiting rotating shafts 33. The two opposite driving guide rollers 34 are meshed and connected by a conveyor belt 35, and limiting grooves 36 for positioning are evenly and equidistantly formed on the outer end face of the conveyor belt 35.

[0042] As Figure 3 , the driving pulley 5 includes a limiting pulley for support and a support gear fixedly connected to the rear of the limiting pulley. The limiting pulley is meshed and connected with the driven pulley 10 through a connecting belt 9. The driving pulley 5 is meshed and connected with the half gear 6 through the support gear. The half gear 6 is an incomplete gear. The user can freely adjust the number of teeth of the half gear 6 according to the distance between the two limiting grooves 36, which is convenient for the subsequent half gear 6 to synchronously provide intermittent power for the conveying device 3 for conveying, and can also provide power for the detection device 1 to cooperate with the conveying of the conveying device 3 to quickly detect food.

[0043] As Figure 9 and Figure 10, the support guide shaft 152 is slidably clamped to the inner end face of the fixed sleeve 124 through the limit clamping block 123. One end of the spring guide ring 153 is fixedly connected to the inner wall of the limit sliding plate 154, and the other end of the spring guide ring 153 is fixedly connected to the limit clamping block 123. When the spring guide ring 153 is in contact with the transmission turntable 114, it is in a compressed state. The spring guide ring 153 can always provide elastic force for the limit sliding plate 154, so that the limit clamping shaft 151 can always be in contact with the outside of the transmission turntable 114 and the connecting sliding plate 111 to improve the stability of guiding.

[0044] Such as Figure 7 and Figure 11 , the height of the connecting sliding plate 111 relative to the transmission turntable 114 is equal to the width of the conveyor belt 35, and the mounting support 155 is directly opposite to the conveyor belt 35. Guide fillets are provided on the sides of the connecting sliding plate 111. When detecting food, the displacement length of the mounting support 155 backward is the length of the connecting sliding plate 111. The height of the connecting sliding plate 111 relative to the transmission turntable 114 is equal to the width of the conveyor belt 35, which can prevent subsequent detection limitations and affect the stability of detection.

[0045] Such as Figure 8 and Figure 9 , the thickness of the connecting cam 115 is equal to the thickness of the support bracket 121, and the bottommost part of the connecting cam 115 is tangent to the bottom end face of the support bracket 121. The support device 12 is slidably clamped inside the support guide rail 14 through the fixed sliding plate 122 adapted to the limit sliding groove 13. During transmission, the connecting cam 115 can drive the support bracket 121 to perform cyclic up and down displacements, and at the same time, cooperate with the front and rear limits of the connecting sliding plate 111 and the limit clamping shaft 151, so that the detection device can automatically perform up and down displacements, thereby completing the rapid detection of food.

[0046] Working principle: Before use, the user can install the adapted detection device at the lower part of the mounting support 155, and then position the external food feeding device in front of the conveying device 3, which is convenient for quickly and stably supplying food to the inside of the limit card slot 36 subsequently, so as to improve the detection efficiency. When detecting food, such as Figure 3, the user can start the servo motor 7 through an external control device. At this time, the servo motor 7 can drive the front half gear 6 to rotate. When the half gear 6 rotates, the half gear 6 can synchronously drive the upper driving pulley 5 and the toothed pulley 4 located outside the half gear 6 to rotate synchronously. When the half gear 6 drives the support gear inside the driving pulley 5 to rotate intermittently, at this time, the support gear can drive the front limit pulley to rotate intermittently. At the same time, the limit pulley can drive the driven pulley 10 to rotate intermittently through the connecting belt 9, so that the driven pulley 10 can drive the limit rotating shaft 33 and the transmission roller 34 to rotate intermittently. And when the limit rotating shaft 33 and the transmission roller 34 rotate intermittently, they can drive the conveyor belt 35 to rotate, so that the conveyor belt 35 can drive the food on the upper part of the limit card slot 36 to be intermittently moved forward for conveying, as Figure 3 , when the half gear 6 rotates, it can also synchronously drive the toothed pulley 4 to rotate, as Figure 1 , the toothed pulley 4 can drive the upper toothed pulley 4 to rotate synchronously through the toothed belt 8, so that the toothed pulley 4 located in the upper part can drive the transmission turntable 114 to rotate. When the transmission turntable 114 rotates, as Figure 8 , the transmission turntable 114 can drive the support device 12 to perform cyclic up and down displacement through the front connecting cam 115. At the same time, when the transmission turntable 114 can also drive the limit clamping shaft 151 to displace backward through the rotating connecting slide plate 111. In the initial state, the mounting seat 155 is located at a high position. At this time, the side with the larger radius of the connecting cam 115 is in contact with the top of the support bracket 121. At this time, the limit card slot 36 is just located directly below the mounting seat 155, as Figure 3 At this time, the meshing between the half gear 6 and the support gear is released. Therefore, in the case where the meshing between the half gear 6 and the support gear is released, first, the connecting cam 115 drives the support device 12 to move downward, so that the mounting seat 155 can fit on the upper part of the food to complete the detection operation. At the same time, when the connecting slide plate 111 rotates subsequently, it can drive the mounting seat 155 to contract backward, so that the detection device is separated from the food until the mounting seat 155 is reset. At the same time, the undetected food can be driven by the next meshing between the half gear 6 and the support gear to drive the limit card slot 36 and the food to move forward. Repeating this process effectively improves the efficiency of detecting food.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
