Abstract
Description
Technical Field
[0001] This utility model relates to the field of sofa processing technology, and in particular to a device for processing residual waste materials from wooden sofas. Background Technology
[0002] A sofa is a multi-seat chair with cushions. It has a backrest made of springs or thick foam and armrests on both sides; it is a type of upholstered furniture.
[0003] After being crushed, waste materials produce compressible scraps. However, these scraps may contain incompletely crushed material. Directly discharging and compressing this scrap could damage the machine and affect the recycling rate. Therefore, there is an urgent need to design and manufacture a device for processing residual waste materials from wooden sofas to meet practical needs. Utility Model Content
[0004] The purpose of this invention is to address existing problems by providing a device for processing residual waste materials from wooden sofas.
[0005] This utility model is achieved through the following technical solution: a device for processing residual waste materials from wooden sofas, including a frame, a housing inside the frame, a roller rotating inside the housing, a plurality of chipping blades evenly distributed on the outer curved surface of the roller, a driven wheel connected to one end of the roller, the driven wheel connected to a driving wheel via a belt, the driving wheel being sleeved on the output shaft of a motor, the motor being installed inside the frame, a screen being provided at the bottom of the housing, an outer shell being connected to the screen at intervals, and a material pipe passing through the bottom of the outer shell.
[0006] As a further improvement to the above solution, several tube seats are evenly distributed on the roller body, and the chip cutter is connected to the internal thread of the tube seat.
[0007] This facilitates the disassembly and assembly of the chipper blades and the adjustment of the number of chipper blades used.
[0008] As a further improvement to the above solution, the chipper includes a stud, which is sleeved in the tube seat. The upper end of the stud is integrally connected to the chip holder, and the chip holder is provided with a chip groove. The chip blade is connected to the chip groove by bolts.
[0009] During the process of crushing waste materials, the chipper blade will experience wear on the blade holder, or even bend or break, as well as wear on the blade itself. The design adopts a disassembly and assembly structure to facilitate the disassembly and replacement of the chipper blade.
[0010] As a further improvement to the above solution, a hopper is connected through the top of the casing, through which materials are fed into the casing.
[0011] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The roller rotates under the drive of the motor, and the roller and the chipper rotate together to crush the wood chips in the shell into wood powder and wood chips. The wood powder and wood chips are filtered through the screen and discharged from the material pipe. Attached Figure Description

[0015] Figure 4 This is a schematic diagram of the chipper blade. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figure 1-4 As shown, a device for processing residual waste materials from wooden sofas includes a frame 1, a housing 2 inside the frame 1, a roller 5 rotatably mounted inside the housing 2, a plurality of chipping blades 7 evenly distributed on the outer curved surface of the roller 5, a driven wheel 8 connected to one end of the roller 5, the driven wheel 8 connected to a driving wheel 9 via a belt, the driving wheel 9 being sleeved on the output shaft of a motor 10, the motor 10 being mounted inside the frame 1, a screen 4 being provided at the lower part of the housing 2, an outer casing 3 being connected to the screen 4 at intervals, and a material pipe 11 being connected through the lower part of the outer casing 3.
[0018] As a further improvement to the above solution, several tube seats 6 are evenly distributed on the roller body 5, and the tube seats 6 are internally threaded to the chip cutter 7.
[0019] This facilitates the disassembly and assembly of the chipper 7 and the adjustment of the number of chipper 7 used.
[0020] As a further improvement to the above solution, the chipper 7 includes a stud 71, which is sleeved in the tube seat 6. The upper end of the stud 71 is integrally connected to the blade holder 72. The blade holder 72 is provided with a blade groove 73, and the blade 74 is connected to the blade groove 73 by bolts.
[0021] During the process of crushing waste materials, the chipper 7 may experience wear on the chipper holder 72, or even bend or break, as well as wear on the blade 74. The chipper 7 is designed with a disassembly structure to facilitate disassembly and replacement.
[0022] As a further improvement to the above solution, the top of the housing 2 is connected to the hopper 12, and materials are fed into the housing 2 through the hopper 12.
[0023] The working principle of a waste processing device for wood sofas: The roller 5 rotates under the drive of the motor 10. The roller 5 and the chipper 7 rotate together to crush the wood chips in the shell into wood powder and wood chips. The wood powder and wood chips are filtered through the screen 4 and discharged from the material pipe 11.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
