Description

Technical Field

[0001] This utility model relates to the field of cutting machinery, specifically a disc cutting machine. Background Technology

[0002] Existing disc cutting machines generally use a disc-shaped cutter head structure, with cutting blades mounted on one side of the cutter head. The cutting blades are driven by the rotation of the cutter head to cut the material.

[0003] However, in practical applications, the circular cutter disc does not achieve ideal cutting results when cutting small logs, bark, and branches with a diameter of about 3 cm. The cut materials are irregular in shape and have a low yield, resulting in poor material utilization and low economic benefits. On the other hand, the feed inlet of existing disc cutters is usually long and rectangular. When conveying or feeding small logs, the logs are prone to swaying in the feed channel, which further aggravates the instability of cutting quality and poor yield. Utility Model Content

[0004] The purpose of this utility model is to provide a disc cutting machine with high cutting efficiency, good cutting quality and wide applicability.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A disc cutting machine, comprising:

[0007] The machine housing has a feed inlet on its front side, and bearing seats are installed on both the front and rear side walls of the machine housing.

[0008] The rotating shaft is fixedly installed between two bearing seats;

[0009] The main drive mechanism is used to drive the rotating shaft to rotate;

[0010] The cutter head is located inside the machine housing and is fixedly sleeved on the rotating shaft;

[0011] A transmission mechanism is located on the front side of the machine casing, and the discharge end of the transmission mechanism is correspondingly located at the inlet.

[0012] The cutter head is frustum-shaped, and several cutting blades are installed on the outer periphery of the cutter head. The cutting blades are arranged circumferentially and are fitted with the feed inlet with clearance. The cutter head is also provided with several receiving ports, which are arranged one by one on the side of the cutting blades. The material cut by the cutting blades falls into the machine housing through the receiving ports.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. Through the frustum-shaped design of the cutter head and the cooperation between the cutter head and several cutting blades, the cutting efficiency of the cutter head is higher and the application range is wider, which significantly improves the cutting quality and sheet yield of materials, resulting in good economic benefits.

[0015] 2. By designing the cross-section of the feed inlet as a square, the material is more stable during the feeding process, and it is less likely to wobble or get stuck, thus achieving the effect of stable feeding and improving the uniformity of the finished product.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0025] like Figure 1-2The diagram shown is a schematic representation of Embodiment 1 of a disc cutting machine provided by this utility model:

[0026] A disc cutting machine, comprising:

[0027] The machine housing 1 has a feed inlet on its front side, and bearing seats 2 are installed on both the front and rear side walls of the machine housing 1.

[0028] The rotating shaft 3 is fixedly installed between the two bearing seats 2;

[0029] The main drive mechanism is used to drive the rotating shaft 3 to rotate;

[0030] The cutter head 5 is located inside the housing 1 and is fixedly sleeved on the rotating shaft 3;

[0031] The transmission mechanism 6 is located on the front side of the housing 1, and the discharge end of the transmission mechanism 6 is correspondingly located at the inlet.

[0032] The cutter head 5 is frustum-shaped, and a number of cutting blades 7 are installed on the outer periphery of the cutter head 5. The cutting blades 7 are arranged circumferentially and are fitted with the feed inlet with clearance. The cutter head 5 is also provided with a number of receiving ports, which are arranged one by one on the side of the cutting blades 7. The material cut by the cutting blades 7 falls into the machine housing 1 through the receiving ports.

[0033] The cross-section of the feed inlet is square.

[0034] It should be noted that the feed inlet of existing disc cutters is usually a long rectangle. When conveying or feeding small logs, the logs are prone to swaying in the feed channel. In this embodiment 1, the cross section of the feed inlet is square, which can effectively prevent logs or other materials from swaying.

[0035] The main drive mechanism includes a frame 8 and a main motor 9; the frame 8 is arranged side by side with the housing 1, the main motor 9 is mounted on the frame 8, and a motor pulley 10 is fixedly sleeved on the output end of the main motor 9. The rear end of the rotating shaft 3 extends out of the housing 1 and is sleeved with a main pulley 11. The main pulley 11 and the motor pulley 10 are connected by belt drive.

[0036] The transmission mechanism 6 includes a mounting frame 61 and a reduction motor 62. The two ends of the mounting frame 61 are respectively rotatably connected to a first pulley 63 and a second pulley 64. The first pulley 63 and the second pulley 64 are connected by a transmission track 65. A drive wheel is sleeved on the output shaft of the reduction motor 62. The drive wheel is connected to the first pulley 63 or the second pulley 64 by a belt.

[0037] Example 2:

[0038] like Figure 3-4The diagram shown is a schematic diagram of Embodiment 2 of the present invention. Embodiment 2 is largely the same as Embodiment 1, except that the transmission mechanism 6 of Embodiment 2 further includes a pressure conveying component 66 to improve transmission efficiency and cutting quality.

[0039] The pressing assembly 66 includes a pressing table 660 and a cover 661 disposed above the pressing table 660; the pressing table 660 is disposed between the mounting frame 61 and the housing 1, and a plurality of first toothed rollers 666 are rotatably connected to the top of the pressing table 660, and the plurality of first toothed rollers 666 are arranged horizontally in sequence.

[0040] The bottom front end of the cover 661 is hinged to the top front end of the pressure conveyor 660. The front side of the cover 661 has a feed inlet 664 corresponding to the conveyor belt 65, and the rear side has a discharge outlet 665 corresponding to the feed inlet. The inner wall of the cover 661 is rotatably connected to a number of second toothed rollers 668, which are arranged downwards from front to back.

[0041] Specifically, the bottom front end of the cover 661 is hinged to the top front end of the pressure table 660 via a hinge shaft 670;

[0042] Furthermore, the pressing assembly 66 also includes a movable frame 671, which is located above the feed inlet 664 and the rear end of the movable frame 671 is hinged to the cover 661; a feed pre-compression roller 667 is rotatably connected to the inner side of the movable frame 671, and a transmission motor 662 for driving the feed pre-compression roller 667 to rotate is installed on the top of the movable frame 671.

[0043] Specifically, the rear end of the movable frame 671 is hinged to the cover 661 via a swing arm 663;

[0044] Furthermore, a limiting pressure roller 669 is provided above the discharge port 665, and the limiting pressure roller 669 is rotatably connected to the inner wall of the machine cover 661.

[0045] The working principle of the pressure feeding component 66 in this embodiment 2 is roughly as follows:

[0046] The material first passes through the feeding pre-compression roller 667. The feeding pre-compression roller 667 is driven by force to lift the movable frame 671 along its hinge (i.e., the swing arm 663). Then, the feeding pre-compression roller 667 is driven to rotate by the transmission motor 662, and the material is moved backward.

[0047] When the material passes the rear end of the second toothed roller 668 and the first toothed roller 666, the second toothed roller 668 is driven by force to lift the cover 661 upward along its hinge axis 670; the movable frame 671 and the cover 661 are hinged together, and when the cover 661 is lifted, it will not affect the position of the movable frame 671, so that each second toothed roller 668 and each first toothed roller 666 can fit with the material and be subjected to balanced force.

[0048] Example 3:

[0049] like Figure 5-7 As shown, this is a schematic diagram of Embodiment 3 of the present invention. Based on Embodiment 1 or Embodiment 2, Embodiment 3 further includes a crushing component 12, which can perform secondary crushing on the material cut by the cutter head.

[0050] The crushing assembly 12 includes several connecting frames 121, several crushing hammers 122, and two locking bolts 123;

[0051] Several connecting frames 121 are fixedly sleeved on the rotating shaft 3 and arranged at intervals on the rear side of the cutter head 5. Each connecting frame 121 has through holes at both ends. Two locking bolts 123 pass through the through holes on the corresponding sides of each connecting frame 121 and lock them in place. Several breaking hammers 122 are fixedly sleeved on the rod of the locking bolts 123 and arranged at intervals on both sides.

[0052] The breaker hammer 122 has a plurality of adjustment holes 1221 that cooperate with the rod portion of the locking bolt 123, and the adjustment holes 1221 are spaced apart along the length of the breaker hammer 122.

[0053] Furthermore, a material inlet is provided at the bottom of the housing 1 corresponding to the position of the crushing component 12.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
