Technical Field

[0001] This utility model belongs to the technical field of wood cutting equipment, specifically relating to a lifting-type multi-blade saw for square timber. Background Technology

[0002] Currently, multi-blade saws for square timber are used to process square timber into pieces, cutting a whole strip of square timber into multiple planks of uniform size. Most existing multi-blade saws for square timber have the cutting machine positioned above the middle of a conveyor belt, with pressure rollers on both sides of the cutting machine. The square timber is transported to the bottom of the cutting machine for cutting with the cooperation of the pressure rollers and the conveyor belt. For this type of multi-blade saw for square timber, the cutting distance is usually adjusted manually. The usual method is to set multiple sets of bolt holes with vertical spacing on both sides of the frame on which the cutting machine is installed, and fix the cutting machine with bolts. When adjusting the distance, it is necessary to manually unscrew the bolts, then raise or lower the machine, and finally screw the bolts back on to fix the distance. In order to make the distance adjustment easier and faster, this solution was developed. Utility Model Content

Detailed Implementation

[0025] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0026] like Figures 1-6 As shown, this embodiment provides a lifting multi-blade saw for square timber, including two pressure rollers 1, a sawdust collection box 2, a conveying platform 3, a lifting assembly 4, and a cutting assembly 5.

[0027] The conveying platform 3 includes a first conveyor belt 31, a second conveyor belt 32 and a cutting plate 33. The first conveyor belt 31 and the second conveyor belt 32 are arranged at intervals. The cutting plate 33 is located between the first conveyor belt 31 and the second conveyor belt 32. Multiple cutting clearance holes are formed on the cutting plate 33. A wood chip collection box 2 is provided below the cutting plate 33. The location of the cutting plate 33 is the cutting area.

[0028] One pressure roller 1 is located above the first conveyor belt 31, and the other pressure roller 1 is located above the second conveyor belt 32. The entry and exit of square timber are achieved through the cooperation of the pressure roller 1, the first conveyor belt 31, and the second conveyor belt 32.

[0029] The cutting assembly 5 is located above the cutting area. Specifically, the cutting assembly 5 includes a cutting frame and a cutting blade. The cutting blade is installed inside the cutting frame. Two spaced-apart lifting platforms 51 are formed on both sides of the cutting frame. One surface of the two lifting platforms 51 on the same side has a through-hole threaded hole, and the other surface has a through-hole guide hole. A saw blade motor is installed on one side wall of the cutting frame, which directly drives the cutting blade to rotate. The cutting blade is a common wood cutting tool used in the market, consisting of a blade holder, a blade, and a blade mounting base, which will not be described in detail in this embodiment.

[0030] The lifting assembly 4 is used to drive the cutting assembly 5 to move up and down. Specifically, the lifting assembly 4 includes two screws 41, two guide rods 42, two drive motors, two fixed bases 43, a top plate 44, and two protective frames 45.

[0031] Two fixed bases 43 are located on both sides of the cutting area of ​​the conveying platform 3. One screw 41 and one guide rod 42 are installed on one fixed base 43. The top plate 44 spans the two fixed bases 43 and the conveying platform 3. The upper ends of the two screws 41 and the guide rod 42 are connected to the top plate 44. The screws 41 are adapted to the threaded holes, and the guide holes are adapted to the guide rods. The two screws 41 are set diagonally, and the two guide rods are set diagonally. The screw pitch of the screws 41 is between 0.5cm and 1cm. A limit component is also provided between the lifting platform 51 with the guide hole and the guide rod.

[0032] The limiting component includes a limiting post 46, and a guide rod is provided with multiple limiting holes 421 spaced vertically. The distance between the axes of adjacent limiting holes 421 is 5-10cm, depending on the specific situation. The lifting platform 51 has an adapter hole 511 on its outward-facing side. The limiting post 46 is adapted and limited by extending into the adapter hole 511 and one of the limiting holes 421. Preferably, there are multiple adapter holes 511, which are spaced vertically. Because the distance between the axes of adjacent limiting holes 421 is small, but setting only one limiting post 46 for load-bearing may cause the limiting post 46 to break, multiple posts are required. In a more preferred embodiment, the guide rod is a prism, and the guide hole is a prismatic hole. The prismatic shape of the guide rod makes it easier to open the limiting holes 421, and the strength of the entire guide rod is not affected when opening the limiting holes 421.

[0033] In a preferred embodiment of this invention, the diameter of the limiting post 46 is smaller than the diameter of the limiting hole 421, with a diameter difference of 0.5cm-1cm. When the screw 41 is raised to the appropriate position, the limiting post 46 is inserted into the corresponding adapter hole 511 and the limiting hole 421. Then, the screw 41 drives the cutting assembly 5 to move downward, ensuring that the cutting assembly 5 can be supported by the limiting post 46 and the guide rod.

[0034] The protective frame 45 is installed between the fixed base 43 and the protective frame 45. Specifically, the protective frame 45 installed on the side of the saw blade motor consists of two U-shaped strips. The U-shaped strips form a channel to avoid the saw blade motor. The two U-shaped strips are used to frame the guide rod and screw 41. The side of the U-shaped strips and the protective frame 45 facing outwards is a switch door. Opening the switch door allows for maintenance and operation of the guide rod and screw 41. The protective frame 45 and the U-shaped strips are used for dust prevention.

[0035] In this embodiment, the drive motor is located above the top plate 44, the upper end of the screw 41 passes through the upper surface of the top plate 44, and a transmission gear is formed at the upper end of the screw 41. The output end of the drive motor has a driving gear, and the driving gear and the driven gear mesh with each other. Specifically, a gearbox can be set between the driving gear and the driven gear to adjust the rotation ratio between the output end of the drive motor and the screw 41.

[0036] In another embodiment, a transmission gear is formed on the lower circumferential surface of the screw 41, and the drive motor is located on one side of the lower end of the screw 41. The output end of the drive motor has a driving gear, and the driving gear and the driven gear mesh with each other. Specifically, a gearbox can be set between the driving gear and the driven gear to adjust the rotation ratio between the output end of the drive motor and the screw 41.

[0037] In this solution, the cutting component 5 is moved up and down by the screw 41, which is more time-saving and labor-saving than the existing manual adjustment. In order to prevent the screw 41 from being unable to support the weight of the cutting component 5, a limit component is also set on the guide rod to bear the weight, ensuring the stability and smoothness of the cutting component 5 during the cutting process.

[0038] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
