DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] In recent years, as an important wood processing equipment, the circular sawing machine is widely used in the construction, furniture and woodworking industry. However, the existing circular sawing machine has some safety hazards in the use process, and in the process of cutting metal pipes, sparks or debris can be scattered in all directions along with the rotation of the saw blade, which can easily burn the skin of the user or injure the eyes of the user, so it is necessary to set a protective cover around the cutting knife.

[0024] However, the protective cover can only block part of the sparks and debris, and if the cutting depth is large and the cutting knife rotates at high speed, part of the sparks and debris can still splash along the edge of the protective cover to the place close to the human body, which brings safety hazards to the operator.

[0025] Please refer to Figure 1 and Figure 2 , in order to solve the above technical problems. The embodiment provides a circular sawing machine, which comprises a cutting table 3, a support 4 rotatably arranged on the cutting table 3, a cutting knife 6 and a driving member 5 for driving the cutting knife 6 to rotate, which are rotatably installed on the support 4, and a protective cover 1 arranged on the support 4 and located outside the cutting knife 6.

[0026] The support 4 is rotatable relative to the cutting table 3, so as to adjust the cutting depth of the cutting knife 6. In order to protect the safety of the operator, the protective cover 1 is arranged outside the support 4, which can effectively block the risk brought by the rotation of the cutting knife 6, reduce the influence of noise and flying debris on the surrounding environment, and ensure the safety and comfort of the operation process. The working principle of the circular sawing machine is that the material is placed on the cutting table 3, and then the driving device is started to drive the cutting knife 6 to rotate at high speed. The rotation of the cutting knife 6 shears the material to achieve the cutting purpose.

[0027] Please refer to Figure 1 and Figure 2 , the protective cover 1 is arc-shaped, and the protective cover 1 is provided with a storage member 2 on the side surface; the storage member 2 comprises a storage block 21 fixedly installed on the protective cover 1, a cavity 22 is formed in the storage block 21, a through hole 23 is formed in the protective cover 1 and communicates with the cavity 22, the length direction of the cavity 22 is the same as the tangential direction of the virtual circle formed by the protective cover 1, a plurality of baffles 24 for placing the rebounding debris are fixedly installed on the inner wall of the protective cover 1, and the included angle between the baffle 24 and the inner wall of the cavity 22 is an acute angle.

[0028] The protective cover 1 realizes the functions of protection and storage by ingenious design. The arc-shaped shell not only protects the surrounding environment, but also has storage blocks 21 arranged on the side surface for intercepting and storing debris and sundries. The storage blocks 21 are provided with cavities 22 connected with through holes 23 formed on the protective cover 1. The length direction of the cavities 22 is consistent with the tangent direction of the arc-shaped protective cover 1. When the spark debris moves in a centrifugal manner in the protective cover 1 due to the rotation of the cutting knife 6, the convenience of dropping the debris into the cavities 22 is ensured. Meanwhile, a plurality of baffles 24 are fixedly installed on the inner wall of the protective cover 1. The baffles 24 form acute angles with the inner wall of the cavities 22, effectively guide the rebound of the debris, and prevent the debris from splashing to the external environment, so as to achieve the purpose of effectively collecting the debris and avoiding external pollution.

[0029] Please refer to Figure 1 and Figure 2 The baffles 24 are distributed on the opposite two inner walls of the cavities 22, so as to intercept the spark debris from multiple directions.

[0030] The storage blocks 21 are provided with first and second inclined surfaces 25 and 26 for changing the rebound direction of the debris away from the protective cover 1. After the spark debris enters the cavities 22, the speed is large, so as to move to the deep part of the cavities 22. When the first and second inclined surfaces 25 and 26 are touched, the splash angle of the activated debris is changed, so that more spark debris is intercepted by the cavities 22 after colliding with the inner wall of the cavities 22, thereby reducing the potential energy.

[0031] Please refer to Figure 2 and Figure 3 The storage blocks 21 include first and second cover blocks 211 and 212, which are fixedly installed on the protective cover 1 by screws.

[0032] By fixing the first and second cover blocks 211 and 212 on the protective cover 1 by screws, not only the first and second cover blocks 211 and 212 can be combined to form a whole, but also the storage blocks 21 can be installed on the protective cover 1. Meanwhile, the two cover blocks can be separated, so that the storage blocks 21 are more flexible and convenient to disassemble and clean. When needed, the two cover blocks are combined together and fixed on the protective cover 1 by screws to complete the installation of the storage blocks 21. When not needed, the two cover blocks can be separated to facilitate cleaning or replacement.

[0033] Please refer to Figure 4 and Figure 5 One of the opposite surfaces of the first and second cover blocks 211 and 212 is provided with a plug hole 213, and the other surface is fixedly installed with a plug rod 214.

[0034] The quick combination function is realized by opening the insertion hole 213 on one side of the first and second cover blocks 212, and fixing the insertion rod 214 on the other side. When the insertion rod 214 is inserted into the insertion hole 213, the first cover block 211 and the second cover block 212 are combined tightly to form an integral whole. The working principle is that the insertion rod 214 and the insertion hole 213 are connected, and two independent parts are quickly connected by simple insertion action, so that convenient assembly and disassembly are realized.

[0035] Please refer to Figure 1 and Figure 2 The protective cover 1 is provided with a cover 27 on the shaft side, the cover 27 rotates around the shaft of the protective cover 1, and the rocker 28 is fixedly installed on the cover 27.

[0036] The cover 27 is designed on the shaft side of the protective cover 1 and can rotate around the shaft, so that the spark debris in the cutting process is intercepted and the heat dissipation function of the protective cover 1 is realized. In the initial state, the cover 27 overlaps the protective cover 1 to form an intact protective barrier, effectively preventing the spark debris from splashing. When the cutting knife 6 is not working, the cover 27 rotates relative to the protective cover 1 to expose the internal space of the protective cover 1, so that the internal heat dissipation can be effectively accelerated to prevent overheating, and the rocker 28 facilitates the rotation of the cover 27.

[0037] The friction block is arranged between the cover 27 and the protective cover 1. In order to prevent the cover 27 and the protective cover 1 from rotating easily, the friction block is arranged between the cover 27 and the protective cover 1, the material of the friction block has a certain friction coefficient with the contact surface, when the cover 27 or the protective cover 1 tries to rotate, the friction block will generate resistance, so that the rotation action becomes difficult, thereby effectively preventing unnecessary rotation. When the user uses the product, even if the cover 27 or the protective cover 1 is accidentally touched, they will not easily rotate, avoiding the security risks caused by accidental opening.

[0038] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
