Description

Technical field

[0001] The utility model relates to the technical field of plate processing equipment, in particular to an improved plate waste crushing device. [Background Technology]

[0002] Boards are flat, rectangular building materials of standard sizes used in the construction industry, often as components for walls, ceilings, floors, and more. Boards can be categorized into two main types: solid wood and engineered wood. Because solid wood has no standardized specifications, engineered wood is the primary material used in the construction industry.

[0003] After the artificial boards are pressed and formed, they need to be cut in order to obtain boards of standard specifications. At the same time, in order to avoid waste, the cut leftovers will be further processed into strips of the required specifications. Finally, the remaining waste will be crushed and recycled to continue making boards.

[0004] On March 14, 2023, the applicant applied for a waste material crushing device for plate materials (application number CN202320480583.7), which includes a main body with a crushing chamber and a drive mechanism, and a crushing tool is provided in the crushing chamber; the crushing tool includes a first shaft, a second shaft, a first saw blade group and a second saw blade group, the first shaft and the second shaft being rotatably arranged in the crushing chamber, forming a plate passage between the first shaft and the second shaft, and the first shaft and the second shaft being connected to the drive mechanism; a first saw blade group and a second saw blade group are provided on both sides of the plate passage, the first saw blade group being mounted on the first shaft, and the second saw blade group being mounted on the second shaft. However, the waste material crushing device has the following defects in actual use: the plate materials are cut and crushed by using saw blade groups arranged in close proximity above and below.

They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. In addition, the terms "first," "second," and the like are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features defined as "first," "second," and the like may explicitly or implicitly include one or more of such features.

[0037] See also Figures 1 to 7As shown, the present invention is an improved plate waste pulverizing device 100, which includes a pulverizing main unit 1 having a pulverizing chamber 11, a pulverizing tool 2 disposed in the pulverizing chamber 11, a first drive assembly 3 connected to the pulverizing tool 2, and a fan pulverizing mechanism 4, wherein the pulverizing tool 2 is used to cut the side of the plate, the first drive assembly 3 is used to drive the pulverizing tool 2 to work, and the fan pulverizing mechanism 4 is used to further cut and pulverize the incompletely pulverized fine strips produced by the pulverizing tool 2.

[0038] The shredding tool 2 includes a first cutting blade assembly 21 and a first shaft 22. The first shaft 22 is horizontally and rotatably disposed within the shredding chamber 11. A plate conveying channel 5 is formed within the shredding chamber 11 above the first shaft 22. The plate conveying channel 5 is used to pass the plates to be processed, and the conveying direction of the plate conveying channel 5 is perpendicular to the first shaft 22. The first cutting blade assembly 21 is mounted at the end of the first shaft 22. When the plates to be processed are conveyed forward through the plate conveying channel 5, the first cutting blade assembly 21 can cut and crush the waste area of ​​the plates. The fan crushing mechanism 4 is disposed above the plate conveying channel 5, and the input end of the fan crushing mechanism 4 is connected to the shredding chamber 11, so that wood chips, small strips, etc. produced by the first cutting blade assembly 21 can enter the fan crushing mechanism 4. In the specific implementation of the present invention, it is necessary to connect the output port of the fan crushing mechanism 4 to a dust suction device (not shown) so that the dust suction device can promptly remove the cut and crushed waste.

[0039] Because the existing waste crushing device uses a saw blade group arranged closely above and below to cut and crush the plate, the debris can easily be squeezed and stuck on the chip discharge port of the saw blade in the saw blade group during the crushing process, thereby affecting the chip discharge effect and reducing the sharpness of the saw blade group. The first cutting blade group 21 is provided with a first shaft 22 at the end thereof, and a first cutting blade group 21 is provided at the end thereof. At the same time, a fan crushing mechanism 4 is provided above the plate conveying channel 5, so that during specific operation, the first shaft 22 can be used to drive the first cutting blade group 21 to cut and crush the side of the plate first, and then the fan crushing mechanism 4 is used to suck the wood chips, fine strips and the like produced by the cutting of the first cutting blade group 21 into the fan crushing mechanism 4 for secondary cutting and crushing. Because the fan crushing mechanism 4 and the first cutting blade group 21 are separately provided instead of being provided in close proximity to each other, it can not only effectively reduce the chips being squeezed and stuck on the chip discharge port of the cutting blade group during the crushing process, thereby ensuring the chip discharge effect and the sharpness of the cutting blade group, but also the first cutting blade group 21 cuts in a vertical direction, and the fan crushing mechanism 4 cuts in a horizontal direction.

Specifically, the lower end of the outer shell 41 can be connected to the crushing host 1, and the bottom of the outer shell 41 is connected to the crushing bin 11. The top of the outer shell 41 is open, so that under the suction of the dust suction device, wood chips, small strips, etc. in the crushing bin 11 can enter the outer shell 41 from the bottom of the outer shell 41; the second shaft 42 is arranged in the outer shell 41 to rotate along the vertical direction, and the second cutting knife group 43 is installed at the lower end of the second shaft 42. Because the second shaft 42 is arranged in the vertical direction and the first shaft 22 is arranged in the horizontal direction, the first shaft 22 can drive the first cutting knife group 21 to perform vertical rotation cutting, and the second shaft 42 can drive the second cutting knife group 43 to perform horizontal rotation cutting; the second driving assembly 44 is installed on the outer shell 41, and the second driving assembly 44 is connected to the second shaft 42, so that the second driving assembly 44 drives the second shaft 42 to rotate.

[0045] Furthermore, a threaded section 421 is formed at the lower end of the second shaft body 42, and the threaded section 421 is equipped with a locking nut 45; the threaded section 421 passes through the connecting seat 431, and the connecting seat 431 is locked to the second shaft body 42 by the locking nut 45. When the second cutting knife group 43 needs to be disassembled, replaced or maintained, the second cutting knife group 43 can be easily removed by simply unscrewing the locking nut 45, which is very convenient to operate.

[0046] In some embodiments of the present invention, in order to meet the support requirements for the second shaft body 42 , a shaft seat 46 is provided on the inner side wall of the outer shell 41 , and the second shaft body 42 is rotatably mounted on the shaft seat 46 .

The side wall of the outer shell 41 is formed with an escape opening 412 at the position corresponding to the first pulley 442 and the second pulley 443. The escape opening 412 is used to allow a second belt 444 to pass through. The second belt 444 passes through the escape opening 412 and is sleeved on the first pulley 442 and the second pulley 443, so that the second drive motor 441 can drive the second shaft 42 to rotate.
