Description

Technical Field

[0001] This utility model relates to the field of sawdust collection technology, and in particular to a cold sawdust collection device. Background Technology

[0002] A saw is a commonly used piece of equipment in metal cutting, cutting metal materials through a high-speed rotating saw blade. During the cutting process, a large amount of sawdust is generated. If this sawdust is not collected in time, it will fly everywhere, polluting the working environment and potentially threatening the safety of operators. Existing methods for collecting cold sawdust mostly involve manual sweeping or simple baffles, which are inefficient and ineffective. Furthermore, the sawdust has a high temperature, which can affect surrounding equipment such as cold saws and sawing rollers. The flying sawdust can easily damage equipment, and the scattered sawdust is difficult to collect, causing significant environmental impact. Therefore, we propose a cold sawdust collection device to solve these problems. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned problems in the prior art and provide a cold saw chip collection device to improve the efficiency and effectiveness of chip collection, improve the working environment, reduce safety hazards, and prevent flying chips from damaging the equipment.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cold saw chip collection device, including a base, a gantry frame fixedly connected to the top of the base, a hydraulic cylinder fixedly connected to the top of the gantry frame, a cover fixedly connected to the output shaft of the hydraulic cylinder, a telescopic sealing mechanism provided on the cover, two pressing and fixing mechanisms provided on the inner wall of the top of the cover, two support plates fixedly connected to the inner wall of the top of the cover, a rotary motor fixedly connected to one side of the left support plate, a saw blade fixedly connected to the output shaft of the rotary motor, a chip collection mechanism provided between the cover and the base, and a controller fixedly connected to one side of the gantry frame.

[0005] A further feature of this invention is that the telescopic sealing mechanism includes a frame-shaped groove formed at the bottom of the cover, a plurality of springs are fixedly connected to the top inner wall of the frame-shaped groove, the bottom ends of the plurality of springs are fixedly connected to the same lifting frame, a stop frame is fixedly connected to the bottom of the lifting frame, and an abutment frame is fixedly connected to the bottom of the stop frame. The lifting frame and the stop frame are both slidably fitted inside the frame-shaped groove, and a rubber pad is fixedly connected to the bottom of the abutment frame.

[0006] By adopting the above technical solution, as the saw blade continues to move downwards and cut, the baffle moves upwards and compresses the spring. Under the action of the rubber pad, the abutment frame, the baffle frame, and the cover, the cutting area of ​​the saw blade can be sealed, preventing sawdust from splashing and injuring workers and equipment. At the same time, the sawdust generated during cutting is intercepted in the space between the rubber pad, the abutment frame, the baffle frame, and the cover, which facilitates the centralized collection and processing of sawdust. As the saw blade continues to move downwards, it can cut the workpiece through the rotating saw blade.

[0007] A further feature of this invention is that the extrusion fixing mechanism includes two cylinders fixedly connected to the inner wall of the top of the cover. A second spring is fixedly connected to the inner wall of the top of the cylinder. A sliding plate is fixedly connected to the bottom of the second spring. A connecting rod is fixedly connected to the bottom of the sliding plate. A pressure plate for fixing the workpiece to be cut is fixedly connected to the bottom of the connecting rod. The two sliding plates are respectively slidably sleeved in the corresponding cylinders.

[0008] By adopting the above technical solution, since there is a certain distance between the rubber pad and the pressure plate and the saw blade, before cutting the workpiece, the downward movement of the cover will cause the pressure plate to first abut against the top of the workpiece. As it continues to move downward, the second spring is squeezed. Under the rebound force of the second spring, the workpiece can be pressed down and fixed. This distance can be the maximum distance of the compression of the second spring, which can stably press down and fix the workpiece. As it continues to move downward, the rubber pad abuts against the top of the base.

[0009] A further feature of this invention is that the sawdust collection mechanism includes multiple discharge holes opened on the top of the base and a vacuum pump fixedly connected to one side of the base. One end of the vacuum pump's suction end is fixedly connected to a filter head. A collection box is slidably fitted inside the base. A flexible tube is fixedly connected to the top of the vacuum pump. An annular tube is fixedly connected to the bottom of the flexible tube. Multiple air blowing pipes are fixedly connected to the bottom of the annular tube. Air blowing nozzles are fixedly connected to the bottom of the air blowing pipes. A door is rotatably connected to the front side of the base.

[0010] By adopting the above technical solution, the vacuum pump is started at the same time as cutting. The vacuum pump can extract the air in the base to form a negative pressure. Under the negative pressure, the sawdust in the cover and the baffle frame can be sucked into the base from the feeding hole. After being filtered and intercepted by the filter head, the sawdust is filtered and intercepted into the collection box for collection and treatment. The filtered air is drawn into the hose and the ring pipe, and finally blown out from multiple air blowing pipes and air blowing nozzles. Under the blowing, the sawdust on the pressure plate and the surface of the workpiece can be blown outward to the base between the workpiece and the abutment frame, which is conducive to the comprehensive absorption and collection of sawdust in the baffle frame.

[0011] A further feature of this invention is that one end of the filter head is fixedly connected to an internally threaded tube, and the internally threaded tube is threadedly sleeved on the outside of the vacuum pump's suction end.

[0012] By adopting the above technical solution, it is easy to disassemble and assemble the filter head, and convenient to clean and replace it regularly, thus ensuring the effect of extracting sawdust.

[0013] A further feature of this invention is that four guide rods are slidably connected to the top of the gantry frame, and all four guide rods are fixedly connected to the top of the cover.

[0014] By adopting the above technical solution, the cover can be guided, making its lifting and lowering more stable.

[0015] The beneficial effects of this utility model are:

[0016] Because the rubber pad and the pressure plate are at a certain distance from the saw blade, before cutting the workpiece, the downward movement of the cover will cause the pressure plate to first abut against the top of the workpiece. As it continues to move downward, the second spring is squeezed. Under the rebound force of the second spring, the workpiece can be pressed down and fixed. This distance can be the maximum distance of the compression of the second spring, which can stably press down and fix the workpiece. As it continues to move downward, the rubber pad abuts against the top of the base.

[0017] As the saw blade continues to move downwards for cutting, the baffle moves upwards to compress the spring. Under the action of the rubber pad, the abutment frame, the baffle frame, and the cover, the cutting area of ​​the saw blade can be sealed, preventing sawdust from splashing and injuring workers and equipment. At the same time, the sawdust generated during cutting is intercepted in the space between the rubber pad, the abutment frame, the baffle frame, and the cover, which facilitates the centralized collection and processing of sawdust. As the saw blade continues to move downwards, it can cut the workpiece through the rotating saw blade.

[0018] 3. While cutting, the vacuum pump is activated, which extracts air from the base to create a negative pressure. Under this negative pressure, sawdust from the cover and the baffle frame is drawn into the base through the feeding hole. After being filtered and intercepted by the filter head, the sawdust is collected in the collection box. The filtered air is drawn into the hose and the annular pipe, and finally blown out from multiple air blowing pipes and nozzles. Under the blowing, sawdust on the pressure plate and the surface of the workpiece is blown outward to the base between the workpiece and the abutment frame, thus facilitating the comprehensive absorption and collection of sawdust in the baffle frame.

[0026] See Figure 1 — Figure 4 This utility model provides a cold saw sawdust collection device, including a base 1, a gantry frame 2 fixedly connected to the top of the base 1, a hydraulic cylinder 3 fixedly connected to the top of the gantry frame 2, a cover 5 fixedly connected to the output shaft of the hydraulic cylinder 3, a telescopic sealing mechanism 6 provided on the cover 5, two pressing and fixing mechanisms 8 provided on the inner wall of the top of the cover 5, two support plates 10 fixedly connected to the inner wall of the top of the cover 5, a rotary motor 12 fixedly connected to one side of the left support plate 10, a saw blade 11 fixedly connected to the output shaft of the rotary motor 12, a sawdust collection mechanism 7 provided between the cover 5 and the base 1, and a controller 9 fixedly connected to one side of the gantry frame 2.

[0027] Specifically, the telescopic sealing mechanism 6 includes a frame-shaped groove 64 opened at the bottom of the cover 5. Several springs 65 are fixedly connected to the top inner wall of the frame-shaped groove 64. The bottom ends of the multiple springs 65 are fixedly connected to the same lifting frame 66. The bottom of the lifting frame 66 is fixedly connected to a baffle frame 61. The bottom of the baffle frame 61 is fixedly connected to an abutment frame 62.

[0028] Specifically, both the lifting frame 66 and the stop frame 61 are slidably fitted into the frame groove 64.

[0029] Specifically, a rubber pad 63 is fixedly connected to the bottom of the abutment frame 62.

[0030] Specifically, the extrusion fixing mechanism 8 includes two cylinders 81 fixedly connected to the inner wall of the top of the cover 5. A second spring 82 is fixedly connected to the inner wall of the top of the cylinder 81. A slide plate 83 is fixedly connected to the bottom of the second spring 82. A connecting rod 84 is fixedly connected to the bottom of the slide plate 83. A pressure plate 85 for fixing the workpiece to be cut is fixedly connected to the bottom of the connecting rod 84.

[0031] Specifically, the two sliding discs 83 are respectively slidably fitted inside the corresponding cylinders 81.

[0032] Specifically, the sawdust collection mechanism 7 includes multiple discharge holes 74 opened on the top of the base 1 and a vacuum pump 71 fixedly connected to one side of the base 1. One end of the vacuum pump 71 is fixedly connected to a filter head 76. A collection box 75 is slidably sleeved inside the base 1. A hose 72 is fixedly connected to the top of the vacuum pump 71. An annular tube 78 is fixedly connected to the bottom of the hose 72. Multiple air blowing pipes 79 are fixedly connected to the bottom of the annular tube 78. Air blowing nozzles are fixedly connected to the bottom of the air blowing pipes 79.

[0033] Specifically, a door 73 is rotatably connected to the front side of the base 1.

[0034] Specifically, one end of the filter head 76 is fixedly connected to an internally threaded tube 77, which is threaded onto the outside of the vacuum pump 71's suction end.

[0035] Specifically, the top of the gantry 2 is slidably connected with four guide rods 4, and all four guide rods 4 are fixedly connected to the top of the cover 5.

[0036] In this invention, the workpiece to be cut is placed on top of the base 1 and within the area between the feed hole 74 and the cover 5. The controller 9 controls the hydraulic cylinder 3, the rotary motor 12, and the vacuum pump 71. The hydraulic cylinder 3 moves the cover 5 downwards, and the rotary motor 12 rotates the saw blade 11. Because the rubber pad 63 and the pressure plate 85 are spaced a certain distance from the saw blade 11, before cutting the workpiece, the downward movement of the cover 5 causes the pressure plate 85 to first contact the top of the workpiece. As it continues to move downwards, the spring 82 is compressed. Under the rebound force of the spring 82, the workpiece is pressed down and fixed. This distance... The maximum spacing of the spring 82 can be used to press down and fix the workpiece. As it continues to move downward, the rubber pad 63 abuts against the top of the base 1. As it continues to move downward and cut, the baffle 61 moves upward and presses against the spring 65. Then, under the action of the rubber pad 63, the abutment frame 62, the baffle 61 and the cover 5, the cutting area of ​​the saw blade 11 can be sealed to prevent sawdust from splashing and injuring workers and equipment. At the same time, the sawdust formed by cutting is intercepted in the space between the rubber pad 63, the abutment frame 62, the baffle 61 and the cover 5, which is conducive to the centralized collection and treatment of sawdust. As it continues to move downward, the workpiece can be cut by the rotating saw blade.

[0037] While cutting, the vacuum pump 71 is started. The vacuum pump 71 can extract the air in the base 1 to form a negative pressure. Under the negative pressure, the sawdust in the cover 5 and the baffle 61 can be sucked into the base 1 through the feeding hole 74. After being filtered and intercepted by the filter head 76, the sawdust is filtered and intercepted into the collection box 75 for collection and processing. The filtered air is drawn into the hose 72 and the annular tube 78, and finally blown out from multiple air blowing pipes 79 and air blowing nozzles. Under the blowing, the sawdust on the pressure plate 85 and the surface of the workpiece can be blown outward to the base 1 between the workpiece and the abutment frame 62, which is conducive to the comprehensive absorption and collection of sawdust in the baffle 61.
