Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] like Figure 1As shown, this utility model discloses a material collection mechanism for injection molding, including: a vibration component 1 and a conveying component 2. The vibration component 1 and the conveying component 2 are connected by a hinge chain 3. Since the vibration direction of the vibration component 1 and the conveying component 2 is different, a hinge chain 3 that can generate multiple degrees of freedom needs to be set. In this embodiment, the hinge chain 3 is formed by hinged two flat plates 31. In other embodiments, the hinge chain 3 can be formed by hinged more flat plates 31.

[0035] Combination Figure 2 As shown, the vibration assembly 1 includes: a material collection plate 11, a crank transmission mechanism and a first servo mechanism 17. One end of the material collection plate 11 is hinged to the hinge chain 3, and the bottom of the other end is equipped with the crank transmission mechanism, which is connected to the first servo mechanism 17. Under the control of the first servo mechanism 17 and the crank transmission mechanism, the material collection plate 11 vibrates up and down along the hinge end of the material collection plate 11 and the hinge chain 3 to disperse the material.

[0036] Combination Figure 10 As shown, the conveying assembly 2 includes: a conveying plate 21, a second base, a transmission rod 24, and a second servo mechanism 26. One end of the conveying plate 21 is hinged to the hinge chain 3, and a mounting seat 212 is provided at the bottom of the conveying plate 21. The mounting seat 212 is located in the middle of the conveying plate 21 and is installed in the second base.

[0037] A transmission groove 213 is provided in the middle of the mounting base 212. The transmission rod 24 abuts against the inner wall of the transmission groove 213 and is connected to the second servo mechanism 26. Under the control of the second servo mechanism 26, the transmission rod 24 rotates along the inner wall of the transmission groove 213, thereby driving the conveying plate 21 to vibrate on the second base for material conveying. In this embodiment, the transmission rod 24 and the second servo mechanism 26 are connected by a synchronous pulley 25.

[0038] In this embodiment, the collecting plate 11 is provided with a first baffle 111 in the circumferential direction, and the side of the collecting plate 11 that is hinged to the hinge chain 3 is hollowed out to prevent the material from falling during vibration. The two sides of the conveying plate 21 and the two sides of the flat plate 31 in the hinge chain 3 are respectively provided with a second baffle 211 and a third baffle 32 to prevent the material from falling during vibration conveying.

[0039] Combination Figure 3 , Figure 4 and Figure 12 As shown, the collecting plate 11 is provided with a first inclined surface 112 to allow the material to move toward the conveying assembly 2. The hinge joint between the third baffle 32 and the first baffle 111 in the hinge chain 3 is provided with an inclined surface 321 that slopes from both sides toward the middle. When the material size is small and the quantity is large, the material is guided from both sides toward the middle to prevent the material from getting stuck at the hinge joint between the third baffle 32 and the first baffle 111.

[0040] like Figures 5 to 7 As shown, in this embodiment, the crank transmission mechanism includes: a crank connector 12, a crank 13, a wheel 14, and a shaft 15. A crank connector mounting base 113 is provided at the bottom of the collecting plate 11. One end of the crank connector 12 is fitted into the crank connector mounting base 113, and the other end is hinged to the crank 13. A first mounting hole 141 is provided at the center of the wheel 14, and a second mounting hole 142 is provided on one side of the first mounting hole 141. The first mounting hole 141 is connected to one end of the shaft 15, and the second mounting hole 142 is hinged to the other end of the crank 13.

[0041] To balance the forces on the crank drive mechanism, two sets of rollers 14 and shafts 15 are provided, respectively hinged to the left and right sides of the crank 13. A first servo mechanism 17 is provided and connected to one of the shafts 15 via a coupling 16. In some other embodiments, two first servo mechanisms 17 can be provided to simultaneously control the rotation of the shafts 15 on both sides. However, the parameters of the two first servo mechanisms 17 need to be adjusted to avoid the crank 13 jamming due to parameter discrepancies.

[0042] Combination Figure 8 and Figure 9 As shown, in this embodiment, the vibration assembly 1 further includes: a first base 18, on which the crank transmission mechanism is mounted. The first base 18 has a hollow portion 181 in the middle to place the rotating wheel 14 and ensure the rotation stroke of the crank 13, and the hollow portion 181 has shaft grooves 183 on both sides to allow the shaft 15 to extend out. The ends of the shaft grooves 183 are also equipped with bearings 184 to reduce the resistance to the rotation of the shaft 15.

[0043] Meanwhile, a first spring mounting seat 114 is provided at the bottom of the collecting plate 11. The first spring mounting seat 114 is located on both sides of the crank connector mounting seat 113, and a corresponding second spring mounting seat 182 is provided on the first base 18. A first spring 19 is installed between the first spring mounting seat 114 and the second spring mounting seat 182 so that the collecting plate 11 can be reset in time during vibration and the vibration amplitude of the collecting plate 11 can be limited, thus protecting the device.

[0044] Secondly, such as Figure 11 As shown, the second base includes a movable base 22 and a fixed base 23. A conveyor plate 21 is mounted on the movable base 22, and at least one guide rod 221 is provided on each side of the movable base 22. The fixed base 23 is provided with an upright plate 231 corresponding to the guide rod 221. The guide rod 221 extends from the upright plate 231, allowing the movable base 22 to be mounted on the fixed base 23, and the movable base 22 to reciprocate along the direction of the guide rod 221. A third spring 28 is fitted between the guide rod 221 and the fixed base 23 to ensure that the movable base 22 returns to its original position in a timely manner.

[0045] The movable seat 22 has a hollow cube shape in the middle. The mounting base 212 of the conveyor plate 21 is located inside the movable seat 22, and the top of the middle part of the movable seat 22 is hollowed out so that the connection between the conveyor plate 21 and the mounting base 212 can extend out. The hollow interior and the hollow top ensure that the conveyor plate 21 has sufficient space to vibrate.

[0046] A third spring mounting seat 214 is provided on the mounting base 212, and a corresponding fourth spring mounting seat 222 is provided at the top of the interior of the movable seat 22. A second spring 27 is installed between the third spring mounting seat 214 and the fourth spring mounting seat 222 so that the mounting seat 214 is suspended inside the movable seat 22. When the conveyor plate 21 moves under the control of the transmission rod 24 and the second servo mechanism 26, since the conveyor plate 21 and the movable seat 22 are connected by the second spring 27, the movable seat 22 moves under the drive of the conveyor plate 21. However, the movable seat 22 is connected to the fixed seat 23 by the guide rod 221. Therefore, the movable seat 22 can only move along the direction of the guide rod 221, which restricts the conveyor plate 21 to reciprocate along the direction of the guide rod 221, causing vibration.

[0047] In addition, in this embodiment, the conveying plate 21 is also provided with wavy protrusions 215 to redisperse and separate the materials during the vibration conveying process.

[0048] The principle of this utility model is as follows: after the injection-molded material falls onto the collecting plate, the material is initially dispersed by the vibration of the collecting plate and transported by the conveying component. After the conveying plate of the conveying component receives the material transported from the collecting plate, it continues to transport it by vibration. The material is further dispersed under the vibration of the conveying component, which makes it easier for the operator to collect and sort the injection-molded products.

[0049] The above description is only a preferred embodiment of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
