Technical Field

[0001] The utility model relates to the technical field of Maschinenbauer sliding table saws, in particular to a dust suction device for Maschinenbauer sliding table saws. Background Art

[0002] The Marsh sliding table saw, also known as the Marsh sawing machine, is a mechanical cutting device that is widely used in the fields of industry and woodworking. The working principle of the device is to achieve cutting through the linear reciprocating motion of the saw blade on the surface of the workpiece. The sliding table saw is generally used for precise cutting of plates, wood, metal, etc.

[0003] During the processing of the Marsh sliding table saw, especially when processing wood, wood chips are easily splashed, causing harm to the workers and polluting the working environment. After the processing is completed, the workers need to clean up, increasing the workload. Therefore, the Marsh sliding table saw needs to be equipped with a dust suction device during operation to reduce the labor intensity of the workers.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original Ma sliding table saw. Utility Model Content

[0005] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution of a dust suction device for a Ma sliding table saw which is significantly different from the existing technology, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust suction device for a Marsh sliding table saw, comprising a saw table, a support frame connected to the frame of the saw table, and a collection cover for protection connected to the support frame, an air supply pipe connected to the collection cover, an end of the air supply pipe connected to one side of the top of a box body, and a saw blade overheating protection structure is connected to the upper side of the outer wall of the box body close to the saw table, a fan is installed on the other side of the outer wall of the box body, a filtering structure is arranged in the box body, the overheating protection structure comprises a cover body, a connecting pipe, a box body, a memory alloy spring, a trigger block, and a trigger switch, a cover body is connected to the bottom of the saw table, a connecting pipe is connected to the cover body, and the connecting pipe is connected to a box body installed at the bottom of the saw table, and the inner wall of the box body is A memory alloy spring is connected to the box body, and a trigger block is connected to the lower end of the memory alloy spring. A trigger switch is installed at the bottom of the inner wall of the box body, and the trigger switch is electrically connected to the motor on the saw table for driving the saw blade to rotate. Another connecting pipe is connected to the other side of the outer wall of the box body, and the other connecting pipe is connected to the box body. The filtering structure includes an open partition, a mounting shaft, a cleaning disk, a filter screen plate, and a baffle. An open partition is horizontally connected to the top of the box body, and the opening of the open partition is rotatably connected to the mounting shaft in the middle opening. A cleaning disk is installed on the mounting shaft, and the end of the brush on the cleaning disk is fitted with the filter screen plate. The filter screen plate is obliquely installed between the top of the open partition and the box body, and a baffle is installed in the box body below the open partition.

[0007] Preferably, the collecting cover is configured as an arc-shaped structure, and the collecting cover is sleeved above the blade of the saw table.

[0008] Preferably, the cover body is configured as a semi-arc structure, and the cover body is sleeved under the saw blade.

[0009] Preferably, the blades on the cleaning disk are arranged in a rectangular shape to increase the contact surface with the air, and the ends of the blades on the cleaning disk are connected with brushes, and at least two baffles are arranged, and the baffles are zigzag distributed in the box.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the dust suction device for the Marsh sliding table saw, through the arrangement of the collecting hood, the air pipe, the box, the fan and the filtering structure, enables the device to shield the flying chips generated when the saw table is working through the collecting hood, and at the same time, the flying chips can be collected into the box under the action of the fan, and the air and wood chips can be filtered and separated through the filtering structure, which is convenient for subsequent processing and collection.

[0011] When the heat accumulated during the continuous operation of the saw blade is too high, the high temperature will accelerate the wear of the tool, reduce the sharpness, and shorten the service life of the tool. Inappropriate temperature will cause oxidation damage to the edge of the blade and may even cause the blade to break. In addition, an overheated saw blade may cause workpiece quality problems such as burning, deformation, and discoloration of the cutting surface, especially for some materials that are highly sensitive to temperature. In addition, an overheated tool may reduce the safety of the operator because high temperature can cause the center of the tool to soften or even break the cutting edge. Therefore, the device is provided with a box body, an overheat protection structure and a fan. On the one hand, the suction force generated by the fan acts on the saw blade through the connecting pipe and the cover body, accelerating the air flow around the saw blade, thereby having a certain air cooling effect on the saw blade. On the other hand, since the air absorbs the heat from the saw blade and enters the connecting pipe, the box body and the box body, when the saw blade is constantly working and the heat accumulates to an excessive level, the temperature of the air entering the connecting pipe and the box body will also be higher. The excessively high temperature is transmitted to the memory alloy spring in the box body, causing it to deform due to heat, pushing the trigger block close to the trigger switch, thereby causing the motor on the saw table that drives the saw blade to rotate to be powered off and stop working, thereby achieving an overheat protection effect.

A trigger switch 606 is installed at the lower part of the inner wall of the box body 603, and the trigger switch 606 is electrically connected to the motor on the saw table 1 for driving the saw blade to rotate. Another connecting pipe 602 is connected to the other side of the outer wall of the box body 603, and the other connecting pipe 602 is connected to the box body 5. The filtering structure 8 includes an opening partition plate 801, an installation shaft 802, a cleaning disc 803, and a filter. Filter plate 804, baffle 805, an open partition 801 is horizontally connected to the top of the box body 5, and the central opening of the open partition 801 is rotatably connected to the installation shaft 802, a cleaning disk 803 is installed on the installation shaft 802, and the end of the brush on the cleaning disk 803 is attached to the filter plate 804, the filter plate 804 is obliquely installed between the top of the open partition 801 and the box body 5, and a baffle 805 is installed below the open partition 801 in the box body 5.

[0018] The collecting cover 3 is configured as an arc-shaped structure, and the collecting cover 3 is sleeved above the blade of the saw table 1 .

[0019] The cover body 601 is configured as a semi-arc structure, and the cover body 601 is sleeved under the saw blade.

[0020] The blades on the cleaning disk 803 are arranged in a rectangular shape to increase the contact surface with the air, and the ends of the blades on the cleaning disk 803 are connected with brushes.

[0021] Working principle: According to Figure 1As shown, the wood to be processed is processed through the saw table 1, and a certain shielding is performed by setting the collecting cover 3 to prevent wood chips from splashing and causing injuries to the staff. The fan 7 is started to generate suction force, which is transmitted to the collecting cover 3 through the air supply pipe 4, and the wood chips are sucked into the box body 5 and filtered through the filter screen 804. At the same time, the air flow entering the box body 5 acts on the cleaning disk 803, driving the cleaning disk 803 and the mounting shaft 802 to rotate, and the cleaning disk 803 cleans the filter screen 804 to prevent blockage, and the cleaned wood chips fall into the box body 5 for collection, which is convenient for subsequent processing;

[0022] At the same time, the suction force acts on the saw blade through the connecting tube 602, the box body 603 and the cover body 601, driving the air flow around the saw blade to move into the connecting tube 602. When the heat on the saw blade is too high, the heat absorbed by the air during flow increases. After entering the box body 603 through the connecting tube 602, the air is transferred to the memory alloy spring 604, causing it to deform after reaching a specified temperature, pushing the trigger block 605 to approach the trigger switch 606, thereby triggering the trigger switch 606 to transmit a signal to the drive motor of the saw blade on the saw table 1, causing it to stop working. This is the working principle of the dust suction device for the Ma sliding table saw.
