Detailed Implementation

[0032] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0033] like Figures 1-11 The high-speed time-controlled scattering mechanism shown has an overall frame including a front frame 4, side plates 5, top plate 6, bottom plate 7, sealing plate 8, and cover plate 9, which are connected by screws. The geared motor 3 is fixed on the motor mounting bracket 18 and is fixed to the bottom plate 7 by screws, pins, and the base plate 7. The main gear set 10 is fixed on the output shaft of the geared motor 3, and the main gear sets mesh with each other. The guide rails 16 are fixed to the inside of the front frame 4 by screws and are symmetrically distributed.

[0034] The synchronous belt drive mechanism 12 consists of a large synchronous pulley 22, a small synchronous pulley 23, a tensioning pulley 24, a T-shaped plate 25, a pressure plate 26, a connecting shaft 27, a first rotating shaft 28, and a synchronous belt 29. The large synchronous pulley 22, the small synchronous pulley 23, and the tensioning pulley 24 are fixed on the first rotating shaft 28. One end of the synchronous belt 29 is pressed by the T-shaped plate 25 and the pressure plate 26, and is installed on the groove of the rear plate 31 of the pre-tensioning mechanism 13 through the connecting shaft 27. The other end is fixed on the protrusion of the pre-tensioning mechanism 13.

[0035] The pre-tightening mechanism 13 consists of a front plate 30, a rear plate 31, a spring 32, a screw 33, and a guide rod 34. The screw 33 passes through the positioning hole of the rear plate 31 and is connected to the threaded hole of the front plate 30. The guide rod 34 is installed in the inner ring of the spring 32.

[0036] The dispensing mechanism 14 consists of a pinion 35, a gear shaft 36, a dispensing shaft 37, and a second rotating shaft 38. The gear shaft 36 is connected and fixed to the dispensing shaft 37.

[0037] The locking mechanism 15 consists of a third rotating shaft 39 and a locking pin 40, etc. The third rotating shaft 39 is installed on the side of the front frame 4, and the locking pin 40 rotates around the shaft to limit the axial displacement of the gear shaft 36.

[0038] Specifically, the geared motor 3 executes corresponding actions according to the instructions issued by the host computer, adjusts the output speed, and throws out the items in the loading plate 17 according to the set grouping, quantity and speed, and controls the mechanism to return to its original position, so as to reload the loading plate 17.

[0039] Specifically, the overall frame serves as the installation base for the mechanism and is made of aluminum alloy. While ensuring strength, the weight of the mechanism is minimized. Multiple cover plates 9 are installed on the frame to facilitate disassembly and maintenance.

[0040] Specifically, the main gear set 10 is responsible for transmitting torque and simultaneously driving the delivery mechanism 14 to move synchronously, so that the items can be smoothly separated and thrown out.

[0041] Specifically, the synchronous belt drive mechanism 12 drives the dispensing mechanism 14 through the coaxial pinion 35 on the one hand, and pulls the pre-tightening mechanism 13 through the T-shaped plate 25 fixed on the rear plate 31 on the other hand, so as to push the filling plate 17 outward to ensure the continuity of scattering.

[0042] Specifically, the pre-tightening mechanism 13 acts as a buffer device. During operation, the spring 32 is always in a compressed state and moves outward as a whole by the traction of the synchronous belt 29. The introduction of the spring 32 avoids the force acting directly on the filling plate 17 and prevents the filling plate 17 from getting stuck due to excessive pressure between it and the delivery shaft 37.

[0043] Specifically, the delivery mechanism 14 is an end effector. The delivery mechanism 14 is symmetrically distributed vertically. The gear shaft 36 and the delivery shaft 37 are connected and reliably fixed by means of center positioning, steps and other structural forms.

[0044] Furthermore, the delivery shaft 37 has three fan-shaped teeth evenly distributed on it, which cooperate with the inclined blocks on the loading plate 17.

[0045] Furthermore, there is a step at the end of the gear shaft 36 for locking the locking pin 40 in the locking mechanism 15.

[0046] Specifically, the locking mechanism 15 mainly restricts the axial displacement of the gear shaft 36. When the filling plate 17 is filling with items, the gear shaft 36 needs to be moved a certain distance towards the locking mechanism 15 so that the sector teeth of the dispensing shaft 37 do not interfere with the inclined block of the filling plate 17, while keeping the gear meshing and preventing disengagement. After filling is completed, the gear shaft 36 needs to be reset. At this time, the locking mechanism 15 is needed to limit it to prevent it from moving left and right.

[0047] Specifically, the structure of the filling plate 17 is adapted to the delivery shaft 37 and the guide rail 16 to ensure continuous stability during the scattering process.

[0048] Preferably, each shaft in the mechanism is equipped with a self-lubricating bearing at both ends to reduce friction during rotation.

[0049] The specific usage process of this invention is as follows:

[0050] 1. Unscrew the screws of the locking mechanism, turn the locking pin, and unlock the gear shaft;

[0051] 2. Move the gear axial locking mechanism to avoid interference between the inclined block of the filling plate and the sector teeth of the delivery shaft;

[0052] 3. Insert the loading plate into the mechanism along the guide rail, paying attention to the placement direction of the inclined blocks of the loading plate;

[0053] 4. Reset the gear shaft;

[0054] 5. Rotate the locking pin and tighten the screw to restrict the lateral displacement of the gear shaft;

[0055] 6. The host computer issues a scattering command, and the motor operates according to the set scattering speed and time;

[0056] 7. The pre-tightening mechanism moves outward under the action of the synchronous belt, so that the filling plate is close to the delivery shaft;

[0057] 8. The dispensing shaft rotates, and the sector teeth drive the loading plate to throw out the items.

[0058] In summary, the present invention has a compact structure, operates stably and reliably, and can achieve precise and rapid spreading.
