Description

Technical Field

[0001] This utility model relates to the field of cutting equipment, specifically a disc cutting machine with toothed chain feeding. Background Technology

[0002] A disc cutter is a device used for crushing, cutting, or pre-treating raw materials. It is widely used in wood processing, paper processing, and solid waste resource utilization.

[0003] Traditional disc cutter feed conveyor mechanisms use rubber belts as conveyor belts. During use, rubber belts are easily torn and worn by materials, belt replacement costs are high, and each belt replacement requires machine downtime, resulting in significant economic losses. Furthermore, the belt is prone to slippage when the tension is insufficient, leading to poor transport efficiency.

[0004] Traditional disc cutting machines typically have a long rectangular feed inlet at the bottom of the feed tube. This type of feed inlet is difficult to effectively limit the material during actual cutting, causing the material to wobble when entering the cutting area, which affects the stability of the cutting process and the quality of the final product.

[0005] Furthermore, traditional disc cutters typically install liners on the inner wall of the feed tube to prevent wear. However, because the bottom of the liner is close to the feed inlet, this part frequently collides with the incoming material, making it prone to wear. Once this part is severely worn, the entire liner often needs to be replaced, resulting in high maintenance costs. Additionally, since this part is located deep within the feed tube, operators must reach inside the tube to remove or install it, which is not only inconvenient but also poses certain safety risks. Utility Model Content

[0006] The purpose of this utility model is to provide a disc cutting machine with toothed chain feeding, which has good conveying effect, convenient maintenance, and good economic benefits.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A disc cutting machine with toothed chain feeding, comprising:

[0009] The housing has bearing seats installed on both the front and rear side walls;

[0010] The rotating shaft is fixedly installed between two bearing seats;

[0011] Drive mechanism, used to drive the rotating shaft to rotate;

[0012] The material discharge end of the conveying mechanism is correspondingly located at the top opening of the square tube;

[0013] The cutter head is located inside the machine housing and is fixedly sleeved on the rotating shaft;

[0014] A square tube is horizontally arranged on the front side of the machine housing, and the bottom feed port of the square tube is connected to the cutting edge of the cutter head;

[0015] The cutter head is equipped with several cutting blades, and the cutting blades are in clearance fit with the feed inlet; the cutter head is also provided with several receiving ports, which are arranged one by one on the side of the cutting blades, and the material cut by the cutting blades falls into the machine housing through the receiving ports.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] 1. By cooperating with the toothed conveyor chain and the V-shaped feed chute, the material can effectively contact the toothed conveyor chain, achieving stable material conveying and avoiding the problems of easy wear and slippage of traditional rubber conveyor belts. Furthermore, the horizontally arranged square tubes further guide the material to cut in an orderly manner, achieving continuous and efficient feeding.

[0018] 2. The diamond-shaped design of the feed inlet ensures that the material is positioned between the first and second wear walls when it comes into contact with the cutter head, reducing the swaying during cutting and improving cutting stability and quality.

[0019] 3. By setting a first liner and a second liner, and cooperating with the first and second sockets, the first liner and the second liner can be quickly replaced, avoiding the need for manual disassembly by reaching into the pipe body, improving replacement efficiency and operational safety. At the same time, only the worn liner parts are replaced, without replacing the entire liner plate, which significantly reduces maintenance costs. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0028] like Figure 1-6 The diagram shown is a schematic representation of an embodiment of a disc cutting machine with toothed chain feeding according to this utility model:

[0029] A disc cutting machine with toothed chain feeding, comprising:

[0030] The housing 3 has bearing seats 4 installed on both the front and rear side walls;

[0031] The rotating shaft 5 is fixedly installed between two bearing seats 4;

[0032] Drive mechanism, used to drive the rotating shaft 5 to rotate;

[0033] The material discharge end of the conveying mechanism is correspondingly located at the top opening of the square tube 1;

[0034] The cutter head 7 is located inside the housing 3 and is fixedly sleeved on the rotating shaft 5;

[0035] Square tube 1 is horizontally arranged on the front side of the machine housing 3, and the bottom feed port 100 of square tube 1 is connected to the cutting port of the cutter head 7.

[0036] The cutter head 7 is equipped with several cutting blades 8, and the cutting blades 8 are in clearance fit with the feed inlet 100; the cutter head 7 is also provided with several material receiving ports, which are arranged one by one on the side of the cutting blades 8, and the material cut by the cutting blades 8 falls into the machine housing 3 through the material receiving ports.

[0037] The drive mechanism includes a main motor 61 and a motor pulley 62. The main motor 61 is arranged side by side with the housing 3, and the motor pulley 62 is fixedly sleeved on the output end of the main motor 61. The rear end of the rotating shaft 5 extends out of the housing 3 and is sleeved with a main pulley 63. The main pulley 63 and the motor pulley 62 are connected by belt drive.

[0038] Furthermore, a material inlet is provided at the bottom of the housing 3.

[0039] The transmission mechanism includes a machine base 141, a feeding trough 142 and a reduction motor 143. The feeding trough 142 is located on the top of the machine base 141. A first sprocket 144 and a second sprocket 145 are respectively provided at both ends of the bottom of the feeding trough 142. The first sprocket 144 and the second sprocket 145 are rotatably connected to the machine base 141.

[0040] A transmission chain 146 is connected between the first sprocket 144 and the second sprocket 145. The reduction motor 143 is fixedly mounted on the machine base 141 and is used to drive the first sprocket 144 to rotate.

[0041] Specifically, the cross-section of the feed trough 142 is V-shaped.

[0042] The square tube 1 has a first wear wall 101, a second wear wall 102 and two connecting walls 103. The first wear wall 101 and the second wear wall 102 are arranged adjacent to each other, and the inner sides of the first wear wall 101 and the second wear wall 102 are opposite to the cutting edge.

[0043] The first wear wall 101 and the second wear wall 102 are respectively provided with a first wear-resistant liner 104 and a second wear-resistant liner 105.

[0044] The feed inlet 100 at the bottom of the square tube 1 is diamond-shaped.

[0045] Specifically, the feed inlet 100 is formed by obliquely cutting the bottom of the square tube 1 from bottom to top.

[0046] The first wear-resistant liner 104 includes a first base liner 1042, and a first insertion port 1011 is provided on the second wear wall 102. The first base liner 1042 is inserted into the square tube 1 through the first insertion port 1011 and fits against the lower inner side of the first wear wall 101.

[0047] The second wear-resistant liner 105 includes a second base liner 1052. A second insertion port 1021 is provided on the connecting wall 103 adjacent to the second wear wall 102. The second base liner 1052 is inserted into the square tube 1 through the second insertion port 1021 and is attached to the lower inner side of the second wear wall 102.

[0048] Furthermore, such as Figure 5As shown, the first wear-resistant liner 104 also includes a first top liner 1041, which is detachably connected to the upper inner side of the first wear wall 101 and is in contact with the inner side of the first wear wall 101.

[0049] The second wear-resistant liner 105 also includes a second top liner 1051, which is detachably connected to the upper inner side of the second wear wall 102 and is in contact with the inner side of the second wear wall 102.

[0050] Furthermore, such as Figure 6 As shown, the first base 1042 is provided with a first hand-held portion 200 extending out of a first socket 1011, and the second base 1052 is provided with a second hand-held portion 201 extending out of a second socket 1021.

[0051] The first wear wall 101 is provided with a plurality of first through grooves 1012, and the first top liner 1041 and the first bottom liner 1042 are provided with a plurality of first threaded holes 1043, and each first threaded hole 1043 is screwed into a first threaded locking member through the first through groove 1012.

[0052] The second wear wall 102 is provided with a plurality of second through grooves 1022, and the second top liner 1051 and the second bottom liner 1052 are provided with a plurality of second threaded holes 1053, and a second threaded locking member is screwed into each second threaded hole 1053 through the second through groove 1022.

[0053] It should be specifically noted that during the material feeding and cutting process, the material collides with the first wear-resistant liner 104 and the second wear-resistant liner 105 under the reaction force generated by the cutting of the cutter head 7. Since the first liner 1042 and the second liner 1052 are located closer to the feed inlet 100 and this area is directly opposite the cutting direction of the cutter head 7, the first liner 1042 and the second liner 1052 are more prone to wear.

[0054] When the first liner 1042 is worn to the point of needing replacement, it is only necessary to remove the first threaded locking member that is screwed into the first threaded hole 1043, and pull the first liner 1042 out of the first insertion port 1011 through the first hand-held part 200 that extends out of the first insertion port 1011. Then, replace the first liner 1042 with a new one, and re-tighten the first threaded locking member to complete the replacement operation. This replacement method does not require manual hand insertion into the pipe body for disassembly and assembly, which is convenient and improves replacement efficiency and operational safety. At the same time, only the worn liner part is replaced, without replacing the entire liner plate, which significantly reduces maintenance costs.

[0055] Similarly, the replacement method of the second liner 1052 is the same as that of the first liner 1042, so it will not be described again here.

[0056] The working principle of this utility model is roughly as follows:

[0057] First, the material is placed in the feed trough 142. Since the feed trough 142 is V-shaped, the material comes into contact with the transmission tooth chain 146 at the bottom of the feed trough 142 under the action of gravity and guidance. Then, the reduction motor 143 starts, drives the first sprocket 144 to rotate, and then drives the transmission tooth chain 146 to transport the material towards the square tube 1.

[0058] When the material is conveyed to the feed inlet 100 at the bottom of the square tube 1, since the feed inlet 100 is diamond-shaped, when the material comes into contact with the cutter head 7, the material is between the first wear wall 101 and the second wear wall 102, which reduces the swaying during cutting and improves cutting stability and cutting quality. Subsequently, the cut material falls into the machine housing 3 through the receiving port on the cutter head 7 and is taken out through the picking port.

[0059] 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.
