[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-5 Existing particleboard raw material screening and testing machines require regular maintenance and are inconvenient to disassemble. To solve this technical problem, this embodiment discloses the following technical content.

[0027] The top cover 2 is fixedly connected to the upper surface of the outer shell 1 by bolts, and the feed port 3 is opened in the middle of the right end of the top cover 2. The front and rear sides of the top of the inner shell 1 are provided with first storage grooves 4, and the first crushing roller 503 and the second crushing roller 505 are slidably connected in the first storage grooves 4.

[0028] Plates are fixedly connected to the top left and right sides of the outer shell 1 and the bottom left and right sides of the top cover 2. The front and rear ends of the plates on the left and right sides of the outer shell 1 and the top cover 2 are connected by stabilizing bolts. A groove is opened at the outer end of the upper surface of the outer shell 1. An annular protrusion is fixedly connected to the outer end of the lower surface of the top cover 2. The annular protrusion at the outer end of the lower surface of the top cover 2 engages with the groove opened on the upper surface of the outer shell 1. The top cover 2 and the feed inlet 3 can be removed from the outer shell 1 by removing the stabilizing bolts that fix the top cover 2. Since the first crushing roller 503 and the second crushing roller 505 in the crushing device 5 are slidably connected in the first placement groove 4, and the motor 501 is fixed to the rear side of the outer shell 1 by bolts, the first crushing roller 503 and the second crushing roller 505 can be pulled upward away from the outer shell 1 after removing the motor 501. After disassembling the screening and testing device according to the above steps, the screening and testing device can be maintained. After maintenance, the components are installed back onto the outer shell 1 in sequence. The above are the disassembly and assembly steps of the screening and testing device.

[0029] Example 2: Existing raw material screening and testing machines for particleboard production suffer from material accumulation during screening, which affects screening efficiency and makes it difficult to prevent clogging. Therefore, this example addresses this issue through the following technical solution: Figure 4 As shown;

[0030] A crushing device 5 is installed on the upper right side of the interior of the outer casing 1. The crushing device 5 is composed of a motor 501, a connecting block 502, a first crushing roller 503, a square groove 504, and a second crushing roller 505. The motor 501 is fixedly connected to the top right side of the rear side of the outer casing 1 by bolts, and the output shaft of the motor 501 is fixedly connected to the connecting block 502. The front side of the motor 501 is connected to the first crushing roller 503. The rear shaft of the first crushing roller 503 has a square groove 504. The connecting block 502 is engaged with the square groove 504. The left side of the first crushing roller 503 is engaged with the second crushing roller 505. The lower middle and lower sides of the interior of the outer casing 1 are fixedly connected to the left and right sides. The middle of the shelf 6 has a through hole 7. The upper end of the shelf 6 is equipped with a first screen plate 8, and the lower end of the shelf 6 is equipped with a second screen plate 16.

[0031] Particleboard raw materials vary in size and shape, requiring screening to separate materials of different sizes based on their dimensions and shape. First, the particleboard raw materials are fed into the screening and testing machine through inlet 3. They are then crushed by crushing device 5. During crushing, motor 501 is started, and its output shaft drives the first crushing roller 503 to rotate. The first crushing roller 503, in turn, drives the second crushing roller 505, which rotates inwards. The particleboard raw materials fall from inlet 3 between the first and second crushing rollers 503 and 505, and after being crushed, fall downwards onto the upper surface of the first screen plate 8. Because the first screen plate 8 is inclined with its left side lower than its right side... The crushing device 5 is located above the right end of the first screen plate 8. The crushed particleboard material rolls from the right end to the left end of the first screen plate 8. During the rolling process, qualified material will be screened by the first screen plate 8 and fall into the second screen plate 16 below. Unqualified particleboard material will be left on the upper left end of the first screen plate 8. The second screen plate 16 is inclined with the left side higher than the right side. Like the first screen plate 8, the particleboard material will roll from the left end to the right end of the second screen plate 16. During the rolling process, it will be screened a second time through the second screen plate 16. Qualified particleboard material will be discharged from the bottom discharge port 17, and unqualified material will remain on the second screen plate 16. Since the inner bottom surface of the outer shell 1 has a structure that converges towards the middle, the bottom discharge port 17 can prevent particleboard material from accumulating on the inner bottom end of the outer shell 1 when unloading.

[0032] Example 3: Existing raw material screening and testing machines for particleboard production leave some material residue inside the machine after screening, making unloading inconvenient. Therefore, this example addresses this issue through the following technical solution: Figures 1-6 As shown;

[0033] The inner right middle and left bottom of the outer casing 1 are both fixedly connected to the first automatic telescopic rod 9, and the output end of the first automatic telescopic rod 9 is fixedly connected to the top plate 10. The top plate 10 is slidably connected in the through hole 7. The left middle and right bottom of the outer casing 1 are both provided with side discharge ports 11, and the side discharge ports 11 are respectively opened at the upper left end of the first screen plate 8 and the upper right end of the second screen plate 16. The left middle and right bottom of the outer casing 1 are both fixedly connected to the guide plate 12, and the left middle and right bottom of the outer casing 1 are both provided with the second storage groove 13. The lower inner end of the second storage groove 13 is fixedly connected to the second automatic telescopic rod 14, and the output end of the second automatic telescopic rod 14 is fixedly connected to the side plate 15. The bottom middle of the outer casing 1 is provided with the bottom discharge port 17.

[0034] After the particleboard raw materials are screened, some particleboard raw materials will remain on the first screen plate 8 and the second screen plate 16. At this time, the above-mentioned particleboard raw materials need to be unloaded. The receiving equipment is placed at the bottom of the side discharge port 11 on the left and right sides of the outer casing 1. First, the second automatic telescopic rod 14 is activated. The output end of the second automatic telescopic rod 14 moves downward with the side plate 15, exposing the side discharge port 11. At this time, particleboard raw materials will be discharged from the side discharge port 11. Then, the first automatic telescopic rod 9 is activated. The output ends of the two sets of first automatic telescopic rods 9, along with the top plate 10, impact the right end of the first screen plate 8 and the left end of the second screen plate 16 respectively. When the top plate 10 impacts the first screen plate 8 and the second screen plate 16, the left end of the first screen plate 8 and the right end of the second screen plate 16 will fold over to assist in unloading and prevent particleboard raw materials from remaining on the first screen plate 8 and the second screen plate 16. After unloading is completed, the side plate 15 is closed, and the particleboard raw materials can continue to be tested.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
