DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0033] Refer to the instruction manual Figure 1-6 As shown, a double-screw water mill includes a frame 1, a first abrasive tool assembly 2, a second abrasive tool assembly 3 and a pushing mechanism 4, the first abrasive tool assembly 1 is slidably connected to the frame 1, the first abrasive tool assembly 1 includes a first motor 21 and a first abrasive tool 22 connected to the first motor 21, the second abrasive tool assembly 3 is fixed to the frame 1, and the second abrasive tool assembly 3 includes a second motor 31 and a second abrasive tool 32 connected to the second motor 31, the pushing mechanism 4 includes a driving device 41 and a blanking plate 46 connected to the driving device 41 and a baffle plate 45, there is a height difference between the blanking plate 46 and the baffle plate 45, the first abrasive tool assembly 2 is connected to the driving device 41, and the driving device 41 is connected to the frame 1 When in use, the driving device 41 drives the first mold assembly 2 to move forward, and the baffle plate 45 on the first movable bracket 42 moves forward. At this time, the unloading plate 46 on the second movable bracket 493 is set with a second screw nut 49 with a thread direction opposite to the first screw nut 48 on the first movable bracket 42, causing the second movable bracket 493 to move backward. At this time, the unloading plate 46 moves backward, so that the unloading plate 46 and the baffle plate 45 on the water mill form a front and back movement. The wood falls downward under the influence of gravity, which greatly increases the amount of wood to be processed by the water mill while reducing the preparation time for wood processing, thereby improving work efficiency. In addition, due to the high precision of the screw rod control, the probability of defective products due to improper unloading position is reduced, and the jamming phenomenon caused by pushing the unloading material in the old existing water mill is reduced.

[0034] As a preferred implementation of this embodiment, the driving device 41 is connected to a first screw rod 48, and the first screw rod 48 is connected to a second screw rod 49 through a synchronous wheel. The first and second screw rods are respectively provided with a first screw rod nut 481 and a second screw rod nut 491, and the first and second screw rod nuts are respectively arranged on the first movable bracket 42 and the second movable bracket 493, and the baffle plate 45 and the blanking plate 46 are respectively arranged on the first movable bracket 42 and the second movable bracket 493, and the threads on the first screw rod nut 481 and the second screw rod nut 491 are arranged in opposite directions, and the driving device 41 drives the first screw rod nut 481 and the second screw rod nut 491 to rotate. While the screw 4 is rotating, the first screw 48 drives the second screw 49 to rotate through the synchronous wheel 492. The rotation of the first screw 48 causes the first screw nut 491 to move forward, thereby driving the first movable bracket 42 connected to the first screw nut 491 to move forward, and the first mold assembly 2 and the baffle plate 45 on the first movable bracket 42 move forward. The second screw nut 49 has a thread direction opposite to that of the first screw nut 481. At this time, the second screw nut 49 drives the second movable bracket 493 to move backward, driving the blanking plate 46 located on the second movable bracket 493 to move backward, thereby causing the wood between the baffle plate 45 and the blanking plate 46 to fall.

[0035] Specifically, a horizontally arranged connecting plate 451 and a vertically arranged adjusting plate 452 are provided between the baffle plate 45 and the first movable bracket 493. A height adjustment hole 453 is provided on the adjusting plate 452. The adjusting plate 452 is connected to the connecting plate 451 through the height adjustment hole 453 to enable height adjustment, so that the gap between the baffle plate 45 and the blanking plate 46 can match wood of different specifications.

[0036] In addition, the first mold assembly 2 is disposed on the first movable bracket 42 , and the frame 1 is fixedly connected to a limit baffle 11 , which is located on one side of the first mold 22 to prevent the first mold 22 from shifting excessively.

[0037] As another preferred implementation of this embodiment, the first movable bracket 42 is provided with several groups of first sliding rods 44 on both sides, and the first sliding blocks 43 that cooperate with the first sliding rods 44 are fixedly connected on both sides of the frame 1, and the first sliding rods 44 are located in the first sliding blocks 43 for sliding.

[0038] Specifically, the second movable bracket 493 is provided with a plurality of groups of second slide bars 471 on both sides, and the second slide blocks 47 cooperating with the second slide bars 471 are fixedly connected on both sides of the frame 1, and the second slide bars 471 slide in the second slide blocks 47.

[0039] As another preferred implementation manner of this embodiment, the water mill also includes a feeding mechanism 5, which includes a side baffle 52 and a baffle platform 53. The side baffle 52 and the baffle platform 5 form a cavity for accommodating materials. A feeding motor 51 is provided on the frame 1, and a baffle block 54 is provided on the output shaft of the feeding motor 51. The baffle block 54 is arranged at the bottom of the cavity, and the control of the material feeding speed by the baffle block 54 is achieved by controlling the rotation of the feeding motor 51.

[0040] Specifically, an annular water pipe 6 is provided at the upper end of the first mold assembly 2 and the second mold assembly 3. The water pipe 6 sprays water on the first mold assembly 2 and the second mold assembly 3 to cool the first mold 22 and the second mold 32 to prevent high temperature from affecting the service life of the equipment.

[0041] In addition, a water receiving trough 7 is provided at the lower end of the first mold assembly 2 and the second mold assembly 3. The water receiving trough 7 is arranged at an angle at the bottom of the frame 1. The water receiving trough 7 is used to collect water sprayed by the water pipe 6. In addition, the inclined design of the water receiving trough 7 can effectively drain water.

[0042] Working principle: This example is a forward and reverse twin-screw wood mill. The first screw 1 and the second screw 6 are adjusted to the position according to the size of the wood. Then, the two screws are connected by a synchronous wheel. Then, multiple woods are placed on the feeding mechanism 10. The feeding mechanism 10 restricts the multi-directional movement of the wood. The wood falls downward to the blanking plate under the influence of gravity. The driving device starts the first screw 1, which drives the first movable bracket 2 to move forward and backward in a straight line. At the same time, the second screw connected to the synchronous wheel also moves forward and backward in a straight line. The starting position is: the blanking plate 9 is in front, the wood is on the blanking plate 9, and the baffle plate 5 is at the back. The vertical spacing between the blanking plate 9 and the baffle plate 5 is determined by the diameter of a piece of wood. When moving forward, the first screw 1 drives the first movable bracket, the connecting piece 3, the adjustment plate 4, and the baffle plate 5 forward, and the second screw 6 drives the blanking plate 9 on the second movable bracket backward. At a certain position, the wood on the blanking plate 1 falls due to the influence of gravity, and the next piece of wood is blocked by the baffle plate 5. During retraction, the first lead screw 1 drives the first movable bracket, connector 3, adjustment plate 4, and material retaining plate 5 backward. The second lead screw 6 drives the blanking plate 9 on the second movable bracket forward. When the wood is caught by the material retaining plate 5 at a certain position, it falls onto the blanking plate 9. When the silo is full, the feed motor rotates, driving the material retaining block to hit the wood, preventing it from falling. This cyclical process utilizes the pitch of the lead screw thread to achieve the purpose of both locking and releasing.

[0043] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0044] 1. This patent greatly increases the amount of wood to be processed while reducing the preparation time for wood processing, thereby improving work efficiency;

[0045] 2. Reduce the probability of defective products due to improper material placement;

[0046] 3. Reduce the material jamming phenomenon that occurs when pushing and unloading materials on the old existing water mill.
