The chains 2 comprise inner links and outer links which are alternately hingedly connected in sequence, wherein the two ends of the outer links are rotatably connected to the adjacent inner links through pins, thereby realizing the serial connection of the chains 2. The pin shaft is arranged vertically to the machine plate 1 so that the top surface of the outer chain link is located on the upper plane.

[0027] A support beam is fixed in the middle of the machine plate 1, and the support beam is an alloy part. A table is fixed on the top surface of the support beam. The size of the table is adapted to the inner space of the circular chain 2. The table is used to shield the components below (such as the sprocket 3, etc.) and provide a plane inside the chain 2 to facilitate signal recognition.

[0028] Some of the outer links are provided with connecting pins 4 extending vertically upwards. There are two connecting pins 4 on one outer link and the two connecting pins 4 are respectively coaxially arranged with the pin shaft on the outer link. A plurality of material receiving mechanisms are arranged above the chain 2. The material receiving mechanisms include a material receiving barrel 5 and a bracket 7. The material receiving barrel 5 and the bracket 7 are detachably connected to the top of the chain 2 and realize the function of synchronous movement with the chain 2. The bottom of the material receiving barrel 5 is provided with two sockets 6 that are gap-matched with the connecting pins 4. The bracket 7 includes a horizontally extending strip plate. The inner side of the strip plate close to the table is provided with a long strip feedback plate 8. The feedback plate 8 extends horizontally and is perpendicular to the line connecting the centers of the two sockets 6, so that it can be perpendicular to the center of the outer link it matches, and corresponds to the diameter of the upper material receiving barrel 5, so as to accurately locate the position of the material receiving barrel 5 of the material receiving mechanism.

[0029] A wheel plate 9 fixedly connected to the strip plate is provided on the outer side of the strip plate away from the table plate. The top side of the wheel plate 9 is integrally formed with one end of the strip plate and is processed by bending a metal sheet. A mounting groove 10 extending vertically upward is provided in the center of the bottom side of the wheel plate 9. A mounting bolt 13 penetrates through the mounting groove 10.

[0030] The middle part of the strip plate is provided with two through holes 12 that are movably plugged with the pin holes, so that the connecting pin 4 passes through the insertion hole 6 (on the bracket 7) and the through hole 12 (at the bottom of the receiving barrel 5) from bottom to top, thereby connecting and driving the butt-jointed barrel 5 and the bracket 7. The installation method of this structure is very simple, and the bracket 7 is directly passed through the connecting pin 4, and then the receiving barrel 5 is placed on the bracket 7 and the insertion hole 6 passes through the connecting pin 4.

[0031] If it is necessary to achieve installation fixation, a threaded hole can be further provided in the center of the upper circular end face of the connecting pin 4, and a screw can be connected to the thread in the threaded hole. The screw head of the screw is larger than the diameter of the shaft pin and also larger than the inner diameter of the socket 6. After the socket 6 at the bottom of the material receiving barrel 5 passes through the connecting pin 4, the screw is tightened to the top of the connecting pin 4 inside the material receiving barrel 5, so that the bottom of the material receiving barrel 5 and the bracket 7 are both limitedly installed on the connecting pin 4 to achieve fixation.

[0032] As described above, the connecting pin 4 is used to achieve the installation and matching with the material receiving mechanism. Figure 1 As shown, two connecting pins 4 can be arranged in each group with one outer link interval, that is, a receiving barrel 5 can be installed secretly with one outer link interval.

[0033] A silo is provided on one side of the rotary conveying mechanism, and a discharge port is provided on the side of the silo close to the chain 2. A material discharge chute 14 is connected and fixed to the edge of the discharge port. The material discharge chute 14 is an inclined chute and has baffles 15 on both sides, which can guide small parts to slide along the material discharge chute 14. A material discharge barrel 16 connected to the lower end of the material discharge chute 14 is provided. The lower receiving barrel 5 extends vertically, and the diameter of the material discharge barrel 16 is smaller than that of the receiving barrel 5. The position of the material discharge barrel 16 corresponds to the position of the chain 2 up and down, and the small parts can be introduced into the receiving barrel 5 after flushing the lower material barrel.

[0034] A mounting plate 17 vertically arranged therewith is fixedly installed in the middle of the material discharge chute 14, and a through hole 18 is provided on the bottom side of the mounting plate 17, through which small parts are discharged, and a cylinder body 19 is fixed on the upper part of the mounting plate 17, wherein the cylinder body 19 adopts an air cylinder, and a cylinder rod telescopically matched therewith is provided at the bottom end of the cylinder body 19, and the cylinder rod is perpendicular to the bottom of the material discharge chute 14, and a hard plate 20 fixedly connected therewith is provided at the bottom end of the cylinder rod, and the hard plate 20 can adopt a metal bending plate, and a sealing block 21 is fixed below the hard plate 20, and the width of the sealing block 21 covers the width of the through hole 18 and is adapted to the slot width of the material discharge chute 14, and the sealing block 21 The height of is higher than the through opening 18. When the cylinder rod is extended, the sealing block 21 covers and blocks one side of the through opening 18 to achieve the closure of the through opening 18. The sealing block 21 is made of sponge, which has good flexibility and elasticity. It is not only low in cost, but also particularly suitable for stopping and unloading small parts. Based on the extremely small size of small parts, when the counting is completed and the through opening 18 is closed, there will still be many small parts passing under the sealing block 21. If a rigid gate or opening and closing component is used, it is easy to damage the small parts or jam the gate structure. The use of sponge can directly press down the small parts that pass through. Through the soft characteristics of the sponge, it is ensured that the small parts will not fall again and the small parts are protected.

[0035] The table is fixed with an identification mechanism, which includes: a vertical rod 22, a horizontal rod 23, a connecting block 24, and a sensor 32;

[0036] The bottom end of the vertical rod 22 is provided with a base fixedly connected thereto, and the base is used to support the vertical rod 22 and can be fixed to the table plate by bolts. The connecting block 24 includes a first slit 25 and a second slit 28 located at both ends. The first slit 25 and the second slit 28 are arranged perpendicular to each other. The inner end of the first slit 25 is provided with a first mounting hole 26 connected thereto. One end of the connecting block 24 is provided with a first fastening bolt 27 penetrating the first slit 25, and the inner end of the second slit 28 is provided with a second mounting hole 29 connected thereto. The end of the connecting block 24 away from the first slit 25 is provided with a second fastening bolt 30 penetrating the second slit 28. The vertical rod 22 penetrates the vertically extending first mounting hole 26 and is locked and fixed by the first fastening bolt 27. The flat rod 23 penetrates the horizontally extending second mounting hole 29 and is locked and fixed by the second fastening bolt 30. Therefore, through the connecting block 24, both the installation height and the swing angle of the flat rod 23 can be adjusted. A mounting seat 31 is provided at one end of the horizontal rod 23 away from the vertical rod 22. The sensor 32 is fixed on the mounting seat 31, and the sensor 32 has a sensing signal emitted downward. The sensor 32 is used in conjunction with the feedback plate 8. When the feedback plate 8 passes under the sensor 32, the sensor 32 captures the position information of the feedback plate 8 and starts unloading.

[0037] Adjust the flat rod 23 so that the sensor 32 at its outer end is located at a position corresponding to the material discharge trough 14. When the material receiving mechanism passes this position, the signal of the sensor 32 is sent to the feedback plate 8. At this time, the material receiving barrel 5 corresponds to the material discharge barrel 16 up and down, the chain 2 stops rotating and starts the material discharge to raise the sealing block 21. After the material discharge is completed, the sealing block 21 falls down to stop the material discharge, and the chain 2 is started to rotate again, completing a set of material discharge. Each material receiving barrel 5 passes through the sensor 32 in turn and is identified, completing a set of material discharge actions.

[0038] The packaging bag is manually placed into the receiving barrel 5. After the material is unloaded, the packaging bag is directly lifted up to obtain a packaged product filled with small parts. It is very convenient and efficient.
