Description

Technical Field

[0001] The utility model belongs to the technical field of saw blade equipment, in particular to a multi-blade saw machine for wood processing with adjustable saw blade spacing. Background Art

[0002] At present, the log multi-blade saw is considered to be the most advanced log board processing machinery in the world today. It has the advantages of fast and smooth feeding, high efficiency, low material consumption, safety and reliability, and low price. A multi-blade saw can produce 20-30 cubic meters of wood per day, which is 4-7 times the processing capacity of an ordinary band saw. At the same time, since the saw blades are hidden inside the casing, the safety is greatly improved. However, the saw blades between the existing log multi-blade saws are mostly fixed, and are fixedly connected to the rotating shaft through a mounting base. This requires that when the saw blades need to be adjusted, the saw blade casing needs to be disassembled and adjusted manually. This step is very cumbersome and inefficient. In view of this, the present solution was created. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a multi-blade saw machine for wood processing with adjustable saw blade spacing, which can adjust the distance between the saw blades.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a multi-blade saw machine for wood processing with adjustable saw blade spacing, comprising a cutting assembly and an adjustment assembly, wherein the cutting assembly comprises a rotating shaft, a plurality of left blade mounting seats, a plurality of right blade mounting seats, and a plurality of saw blades, wherein the saw blades are located between the left blade mounting seat and the right blade mounting seat, and the plurality of left blade mounting seats and the right blade mounting seat are spaced apart and sleeved on the rotating shaft;

[0005] The adjusting assembly includes a left-rotating sleeve, a right-rotating sleeve and a plurality of elastic deformation sleeves, wherein both ends of the rotating shaft have external threads, and the left-rotating sleeve and the right-rotating sleeve have internal threads, and the left-rotating sleeve and the right-rotating sleeve are respectively sleeved on both ends of the rotating shaft; the elastic deformation sleeve is arranged on the rotating shaft and is located between the adjacent left mounting seat of the sheet body and the right mounting seat of the sheet body, and the elastic deformation sleeve is located between the left-rotating sleeve and the left mounting seat of the sheet body and the right mounting seat of the sheet body, and the circumferential surface of the left mounting seat of the sheet body and the right mounting seat of the sheet body have a first through hole passing through the upper and lower surfaces, and the rotating shaft has a second through hole, and the left mounting seat of the sheet body and the right mounting seat of the sheet body are connected to the rotating shaft by bolts or pins passing through the first through hole and the second through hole.

[0006] Furthermore, the distance between adjacent first through holes is 1-3 times the distance between adjacent second through holes.

[0007] Furthermore, the left mounting seat of the sheet body and the right mounting seat of the sheet body have the same structure. The left mounting seat of the sheet body includes a mounting plate and a mounting convex ring. The middle part of the mounting plate has a mounting hole. The mounting convex ring is located on the surface of the mounting plate and its axis coincides with the axis of the mounting hole. A limiting ring groove is formed on the inward side of the end face of the mounting convex ring, and the elastic deformation sleeve is located in the limiting ring groove.

[0008] Furthermore, the second through hole is located on the mounting protruding ring, and the depth of the limiting ring groove is less than the minimum distance between the second through hole and the end surface of the mounting protruding ring.

[0009] Furthermore, the elastic deformation sleeve is a spring.

[0010] Furthermore, polygonal protrusions are formed on the outward surfaces of the left-handed sleeve and the right-handed sleeve.

[0011] Furthermore, the distance between adjacent second through holes is 4-6 cm.

[0012] Furthermore, the rotating shaft is a hollow rotating shaft.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model is used to adjust the distance between multiple saw blades by setting an adjustment component. This solution has multiple groups of left-hand mounting seats of the sheet body, right-hand mounting seats of the sheet body and saw blades installed therebetween. The left-hand mounting seat of the sheet body, the right-hand mounting seat of the sheet body and the saw blade sleeves are arranged on the rotating shaft. When the second through holes on the left-hand mounting seat of the sheet body and the right-hand mounting seat of the sheet body and the first through hole on the rotating shaft are not connected by bolts or pins, the multiple elastic deformation sleeves are compressed by rotating the left-hand sleeve and the right-hand sleeve inward, thereby realizing the distance adjustment between the multiple saw blades. After the adjustment is completed, the bolts or pins are inserted into the first through hole and the second through hole, so that the left-hand mounting seat of the sheet body and the right-hand mounting seat of the sheet body are fixed, and the adjustment is completed. Since the present solution adopts bolts or pins to be inserted into the first through hole and the second through hole to realize fixation, the distance between adjacent second through holes is the adjustable distance of the multiple saw blades, and the adjustable distance is in multiple relationship according to the distance between the second through holes.

[0021] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0022] like Figure 1-Figure 5 As shown, this embodiment provides a multi-blade saw machine for wood processing with adjustable saw blade spacing 14 , comprising a cutting assembly 1 , an adjusting assembly 2 , a mounting frame 3 and a rotating assembly.

[0023] The cutting assembly 1 includes a rotating shaft 11, a plurality of left blade mounting seats 12, a plurality of right blade mounting seats 13, and a plurality of saw blades 14. The saw blades 14 are located between the left blade mounting seat 12 and the right blade mounting seat 13. The plurality of left blade mounting seats 12 and right blade mounting seats 13 are spaced apart and sleeved on the rotating shaft 11. The rotating shaft 11 is a hollow rotating shaft 11 having a plurality of second through holes 111 spaced apart and extending through the rotating shaft 11. External threads are formed on both sides of the rotating shaft 11.

[0024] The adjustment assembly 2 includes a left-handed sleeve 21, a right-handed sleeve 22, and a plurality of elastically deformable sleeves 23. The left-handed sleeve 21 and the right-handed sleeve 22 have internal threads and are respectively mounted on both ends of the rotating shaft 11 and are rotatably connected. Specifically, the left-handed sleeve 21 and the right-handed sleeve 22 have polygonal protrusions formed on their outwardly facing surfaces, which are hexagonal protrusions in this embodiment, to facilitate rotation with a wrench. The elastically deformable sleeves 23 are mounted on the rotating shaft 11 and are located between the adjacent left and right mounting seats 12 and 13 of the sheet body. The elastically deformable sleeves 23 are located between the left-handed sleeve 21 and the left mounting seat 12 of the sheet body, and between the right-handed sleeve 22 and the right mounting seat 13 of the sheet body. Specifically, the elastically deformable sleeves 23 are springs. The left sheet body mounting seat 12 and the right sheet body mounting seat 13 have the same structure. The circumference of the left sheet body mounting seat 12 and the right sheet body mounting seat 13 has a first through hole 1221 that runs through the upper and lower surfaces. The left sheet body mounting seat 12 and the right sheet body mounting seat 13 are connected to the rotating shaft 11 by bolts or pins passing through the first through hole 1221 and the second through hole 111. Specifically, the distance between adjacent first through holes 1221 is 1-3 times the distance between adjacent second through holes 111. Preferably, the distance between adjacent second through holes 111 is 4-6 cm. When the distance between the second through holes 111 is 4 cm, by rotating the left-rotating sleeve 21 and the right-rotating sleeve 22, the distance between adjacent saw blades 14 can be adjusted to 2 cm, 4 cm and 6 cm, etc. Similarly, when the adjacent distance is 5 cm, the distance between adjacent saw blades 14 is 2.5 cm, 5 cm and 7.5 cm, etc., and when the adjacent distance is 6 cm, the distance between adjacent saw blades 14 is 3 cm, 6 cm and 9 cm, etc.

[0025] In a more preferred embodiment of the present embodiment, the left mounting seat 12 of the sheet body includes a mounting plate 121 and a mounting protruding ring 122. The mounting plate 121 has a mounting hole in the middle. The mounting protruding ring 122 is located on the surface of the mounting plate 121 and its axis coincides with the axis of the mounting hole. A limiting ring groove 1222 is formed on the inward side of the end face of the mounting protruding ring 122. The elastic deformation sleeve 23 is located in the limiting ring groove 1222. The second through hole 111 is located on the mounting protruding ring 122. The depth of the limiting ring groove 1222 is less than the minimum distance between the second through hole 111 and the end face of the mounting protruding ring 122. Through the above arrangement, the arrangement of the elastic deformation sleeve 23 can be guaranteed without affecting the installation and fixation of the bolts and pins, and the elastic deformation sleeve 23 can be limited to prevent the elastic deformation sleeve 23 from shaking.

[0026] The cutting assembly 1 and the adjusting assembly 2 are installed in the mounting frame 3. The two ends of the rotating shaft 11 in the cutting assembly 1 are rotatably connected to the two ends of the inner wall of the mounting frame 3. One end of the rotating shaft 11 extends out of the side wall of the mounting frame 3. The rotating assembly includes a rotating motor and a speed-changing gear set. The extended end of the rotating shaft 11 is driven to rotate by the cooperation of the rotating motor and the speed-changing gear set. The cooperation between the rotating assembly and the rotating shaft 11 is realized by a common and commonly used driving method in the prior art, which will not be elaborated here.

[0027] The present invention is used to adjust the distance between multiple saw blades 14 by setting an adjustment component 2. This solution has multiple groups of left sheet body mounting seats 12, right sheet body mounting seats 13 and saw blades 14 installed therebetween. The left sheet body mounting seats 12, the right sheet body mounting seats 13 and the saw blades 14 are sleeved on the rotating shaft 11. When the second through hole 111 on the left sheet body mounting seat 12 and the right sheet body mounting seat 13 and the first through hole 1221 on the rotating shaft 11 are not connected by bolts or pins, the left-rotating sleeve 21 and the right-rotating sleeve 22 are rotated inward to compress the multiple elastic deformation sleeves 23, thereby realizing the distance adjustment between the multiple saw blades 14. After the adjustment is completed, the bolts or pins are inserted into the first through hole 1221 and the second through hole 111, so that the left sheet body mounting seat 12 and the right sheet body mounting seat 13 are fixed, and the adjustment is completed.
