[0015] Roller follower: also known as roller bearing follower, it is a high-performance shaft bearing with needle rollers inside, which are called needle rollers; the needle rollers play a role in improving the rotational capacity and can withstand high-speed rotation.

[0016] Servo motor: refers to the motor that controls the operation of mechanical components in a servo system. It is a type of auxiliary motor with indirect speed change.

[0017] Please see Figures 1 to 8 According to an embodiment of the present invention, a positioning and shelling device 4 for processing plant fruits is installed above a positioning and conveying device 300 to complete the shelling of the products to be processed that have moved to its processing station.

[0018] Please see Figures 9 to 13 The positioning and conveying device 300 is used to move the products to be processed sequentially to the processing stations of the ring-shaped fixed-size cutting device 3 and the positioning and shelling device 4, and to convey the shelled products out.

[0019] The positioning transmission device 300 includes a transmission bracket 43, a base mounting plate 34, a servo motor 36, and a friction support bar 38.

[0020] The bottom of the transmission bracket 43 is provided with feet 29 for adjusting the levelness; the base mounting plate 34 is provided at the top of the transmission bracket 43; one end of the base mounting plate 34 is provided with a driven wheel support frame 30, and the other end is provided with a drive wheel support frame 35 and a receiving plate 37. A driven sprocket 32 ​​is provided on the driven wheel support frame 30 through a bearing seat assembly 31, and a drive sprocket 45 is provided on the drive wheel support frame 35 through a bearing seat assembly. A servo motor 36 is provided on the outside of the drive wheel support frame 35, and the output end of the servo motor 35 is connected to the rotation shaft of the drive sprocket 45. A chain 44 is provided between the driven sprocket 32 ​​and the drive sprocket 45.

[0021] Friction support bar 38 is set below chain 44 by several support bars 39 and several support columns 40. Friction support bar 38 is used to support chain and prevent chain sagging, and at the same time can reduce the tension force of chain tensioning device; tension block 41 is provided on base mounting plate 34; dust collection cover 42 is provided on the outside of chain 44; multiple positioning fixtures 33 are arranged side by side on chain 44.

[0022] When the positioning and transmission device 300 is working, the servo motor 35 drives the drive sprocket 45 to rotate, which in turn drives the chain 44 to move, thereby driving multiple positioning fixtures 33 on the chain 44 to move forward sequentially through the cutting processing station 3 and the shelling processing station 4.

[0023] Please see again Figure 10 , Figure 11 and Figure 12 Each positioning fixture 33 includes a positioning support frame 48, a driving synchronous pulley 46, a driven synchronous pulley 61, and a synchronous toothed belt 53. The positioning support frame 48 is longitudinally mounted on the chain 44; the driving synchronous pulley 46 is mounted at the rear end of the positioning support frame 48 via a driving pulley mounting bracket 47, and the driven synchronous pulley 61 is mounted at the front end of the positioning support frame 48 via a tensioning bracket 60; a linear slide rail 55 is longitudinally mounted on the positioning support frame 48, and two support plates 51 are mounted one in front of the other on the linear slide rail 55; two stop posts 56 are mounted one in front of the other on the positioning support frame 48, and the two support plates 51 are located between the two stop posts 56; each support plate 51... Each pulley has an auxiliary synchronous pulley 57 connected by a hinge pin 59, a buckle, and an oil-free bushing. The synchronous toothed belt 53 is tensioned between the driving synchronous pulley 46 and the driven synchronous pulley 61, and the inner side of the synchronous toothed belt 53 is connected to the auxiliary synchronous pulley 57. A belt support 52 is installed on the outer side of the connection between the synchronous toothed belt 53 and the auxiliary synchronous pulley 57. The belt support 52 allows the belt teeth of the synchronous toothed belt 53 to better engage with the synchronous pulley during operation, thereby better driving the auxiliary synchronous pulley 57 to rotate.

[0024] Each auxiliary synchronous pulley 57 has a rubber support ring 58 bonded to its top for supporting the product. When the auxiliary synchronous pulley 57 rotates, the product placed on the rubber support ring 58 can rotate. Each support plate 51 is provided with a roller follower 54, and the roller follower 54 is located outside the synchronous toothed belt 53. The roller followers 54 on the two support plates 51 are respectively located on the left and right sides of the positioning support frame 48. Each support plate 51 is equipped with a spring tensioning mechanism, which is used to pull the two support plates 51 to both sides. Each spring tensioning mechanism includes two spring tensioning frames 49 and a tensioning spring 50. The two spring tensioning frames 49 are respectively set on the support plate 51 and the positioning support frame 48, and the two ends of the tensioning spring 50 are respectively connected to the two spring tensioning frames 49.

[0025] Please see again Figure 13Multiple positioning fixtures 33 are arranged side-by-side on the chain 44. Roller followers 54 on the two support plates 51 of each positioning fixture 33 are positioned on the left and right sides of the positioning support frame 48. The roller followers 54 of adjacent positioning fixtures 33 are arranged one after the other. When a guide block 75 passes between two roller followers 54, it increases the distance between the two support plates 51, thereby adjusting the distance between the rubber support rings 58 at the top of the two auxiliary synchronous pulleys 57. After the guide block 75 passes through, the distance between the two support plates 51 is restored under the action of the spring tensioning mechanism, thus restoring the distance between the rubber support rings 58 at the top of the auxiliary synchronous pulleys 57. This allows for the adjustment of the front-to-back distance between products within the two rubber support rings 58.

[0026] When in use, the positioning and conveying device 300 transports the products to be processed into the rubber support rings 58 on the positioning fixtures 33 of the positioning and conveying device 300. Each positioning fixture 33 has two products on it. The positioning fixtures 33 can rotate the products placed on the rubber support rings 58. As the chain 44 moves, the rotation position and left and right distance of the products can be adjusted. As the chain 44 moves, the products on each positioning fixture 33 are first cut by the ring-shaped fixed-size cutting device 3, and then deshelled by the positioning and deshelling device 4. After deshelling, the products move with the chain 44 to the receiving plate 37, and slide down the receiving plate 37 for subsequent sorting and packaging processes.

A deshelling arc-shaped guide rail is provided between the deshelling drive sprocket 127 and the deshelling driven sprocket 128. The deshelling arc-shaped guide rail is used to guide the pressing fixture to make a circular motion.

[0029] Each shell removal fixture 131 includes a shell removal mounting bracket 139, a shell removal mounting bracket 137, and two shell removal mechanisms. The shell removal mounting bracket 137 is fixed to the shell removal chain 126 by screws, and the shell removal mounting bracket 139 is positioned above the shell removal mounting bracket 137 via a support column 138. The two shell removal mechanisms are arranged one in front of the other. Each shell removal mechanism includes a guide mounting column 149 and two clamping blocks 143, which are symmetrically arranged on the shell removal mounting bracket 137. A clamping block spring tensioning mechanism one 140 and a clamping block spring tensioning mechanism two 147 are respectively provided on the outer sides of the two clamping blocks 143. The clamping block spring tensioning mechanism one 140 and the clamping block spring tensioning mechanism two 147 are used to adjust the distance between the two clamping blocks 143. Each clamping block 143 is equipped with a shell-removing clamp 141 via a hinge pin 148, and a roller follower 142 is provided at the outer end of each shell-removing clamp 141. A guide mounting post 149 is located between two clamping blocks 143, and the bottom end of the guide mounting post 149 passes through the shell-removing mounting bracket 139 and the shell-removing mounting bracket 137 in sequence. A follower mounting bracket 136 is provided at the bottom end of the guide mounting post 149, and roller followers 135 are respectively provided at the front and rear ends of the follower mounting bracket 136.

[0030] Please see again Figure 7 and Figure 8The shell-removing arc-shaped guide rail includes four arc-shaped guide brackets 84 arranged sequentially from front to back. Each arc-shaped guide bracket 84 includes two arc-shaped guide blocks 108 and 109 arranged in a mirror symmetrical manner and a horizontal connecting strip 107 for connecting the two arc-shaped guide blocks. The first two arc-shaped guide brackets 84 form one guide rail, and the last two arc-shaped guide brackets 84 form another guide rail. The roller followers 135 at the bottom of the two guide mounting columns 149 of each shell-removing fixture make circular movements along the two guide rails in a one-to-one correspondence.

[0031] Please see again Figure 6 Four clamping guide blocks 150 are arranged sequentially from front to back on the lower part of the middle of the shelling support plate 121. When each shelling fixture 131 moves to the clamping guide block 150 with the shelling fixture transmission mechanism, the roller follower 142 at the outer end of the shelling clamp 141 of the four clamping blocks 143 passes through the four clamping guide blocks 150 one by one. Under the guidance of the corresponding clamping guide block 150, each roller follower 142 drives the corresponding shelling clamp 141 to move and clamp the fruit shell. After each roller follower 142 passes through the corresponding clamping guide block 150, the roller follower 142 drives the shelling clamp 141 to return to its original position and remove the fruit shell.

[0032] The positioning shelling device 4 for processing plant fruits of the present invention is used to complete the shelling and kernel extraction process of nuts. After the product on the positioning fixture 33 is cut in a ring shape, it is driven by the chain 44 to the shelling area of ​​the positioning shelling device 4.
