Description

Technical Field

[0001] The present application relates to the technical field of negative pressure dust collection tooling, and specifically discloses a negative pressure dust collection tooling. Background Art

[0002] The negative pressure vacuum system uses the negative pressure generated by the negative pressure fan to draw dust-laden air into the equipment. The air is then filtered through the filter, the dust is separated and collected, and the purified air is discharged. This working principle enables the negative pressure vacuum system to effectively remove particles, dust and pollutants in the air;

[0003] Most of our products are products with skeleton frames;

[0004] After the product with skeleton frame strips is finely cut, there is a lot of dust on the end, which needs to be blown away with an air compressed air gun, causing dust pollution in the workplace.

[0005] Therefore, in order to reduce dust pollution on the work site, our company has designed a negative pressure dust collection tool in the precision cutting process. Summary of the invention

[0006] The purpose of the invention is to solve the problem that dust in the traditional fine cutting process is difficult to handle.

[0007] In order to achieve the above object, the present invention provides the following basic scheme:

[0008] A negative pressure dust collection tool, comprising a negative pressure box, a control box arranged on the negative pressure box for controlling the negative pressure box, a collection box arranged on one side of the negative pressure box, a negative pressure pipe connected to the collection box, and a negative pressure dust collection assembly arranged on the collection box and connected to the collection box, wherein the negative pressure pipe is connected to an air extractor;

[0009] The negative pressure dust suction component comprises a flared pipe, a heating pipe connected to the flared pipe, and a workpiece induction component arranged on the heating pipe.

[0010] The principles and effects of this basic solution are:

[0011] 1. Compared with the existing technology, this device has a simple structure and ingenious design. Since the end of the frame strip product needs to be blown away with an air gun after fine cutting, which causes dust pollution in the workplace, negative pressure adsorption tooling and induction elements are added to the industrial vacuum cleaner to automatically detect the product to start vacuuming and delay the stop of vacuuming after the product is separated. This saves energy and improves the workplace environment.

[0012] 2. Compared with the prior art, the present device makes improvements on industrial vacuum cleaners, improves the negative pressure effect, rationally utilizes the sensing element to automatically detect the time when the product starts vacuuming, designs a heating tube, and utilizes the heating tube to realize pipe heating. By heating the gas, the thermal motion of the gas molecules can be increased, and its kinetic energy can be increased, thereby increasing the flow rate. The faster the flow rate, the smaller the pressure, and the more obvious the negative pressure effect is, thereby improving the negative pressure effect.

[0013] 3. Compared with the prior art, the present device makes improvements on the industrial vacuum cleaner, improves the negative pressure effect, and sets a third tube body. The third tube body is used to narrow the flow channel, which can accelerate the gas when passing through. The faster the flow rate, the lower the pressure, and the more obvious the negative pressure effect is, thereby improving the negative pressure effect.

[0014] 4. Compared with the prior art, since the third tube body can accelerate the gas when passing through, the outlet position is further improved at this time, and a flaring group is set. The flaring group is a purely mechanical mechanism. By controlling whether the flaring group is open, when the flaring group is not open, the outlet diameter is small, the internal air pressure will become larger and larger, and the greater the resistance encountered when the gas passes through, when it increases to a limited value, the flaring group opens, the outlet diameter becomes larger instantly, and after the gas pressure is increased, the air pressure begins to drop instantly, and the flow rate begins to increase rapidly. The faster the flow rate, the smaller the pressure, and the more obvious the negative pressure effect is, thereby improving the negative pressure effect.

[0033] The handle 3 is used to move the entire device, making it easier to move the entire device.

[0034] A slot is provided at the connection between the collecting box 6 and the negative pressure pipe 5, in which a filter plate 4 is detachably connected, a handle 3 is provided on the top of the filter plate 4, a sealant is provided at the connection between the filter plate 4 and the slot, and a filter screen is installed on the filter plate 4.

[0035] A filter is provided to filter large impurities to prevent them from entering the vacuum pump.

[0036] About the vacuum extractor: The vacuum extractor is started by the control box 1 to realize the vacuum operation, and the pressure is reduced by changing the flow rate inside the negative pressure suction component, thereby forming a pressure difference between the inside and the outside, thereby forming a negative pressure environment;

[0037] The negative pressure dust suction component includes a flared tube 7 , a heating tube 8 connected to the flared tube 7 , and a workpiece sensing component arranged on the heating tube 8 .

[0038] About Workpiece Sensing Components:

[0039] The workpiece sensing assembly includes a connecting hole opened at one end of the heating tube 8, a ring 9 sleeved on one end of the heating tube 8, a mounting frame 12 and an infrared sensor 10 arranged in the ring 9, the infrared sensor 10 includes an infrared sensor receiver and an infrared sensor transmitter, the infrared sensor receiver and the infrared sensor transmitter are respectively installed at the connecting hole position, the workpiece and the mounting frame 12 are detachably connected, the workpiece can block the connection between the infrared sensor receiver and the infrared sensor transmitter, and a mounting block 11 is provided at the bottom of the ring 9, the mounting block 11 has a mounting groove, the mounting groove and the connecting hole form a matching position, and the matching position is used for the installation of the external sensor receiver and the infrared sensor transmitter.

[0040] The infrared sensor receiver and the infrared sensor transmitter need to be provided with a time control sensor. Since the workpiece and the mounting frame 12 are placed manually, time reaction is required, and the subsequent negative pressure dust collection component also needs time reaction. Therefore, a time control sensor is provided to adapt the negative pressure dust collection component.

[0041] like Figure 3 and Figure 4 As shown:

[0042] The heating tube 8 comprises a first tube body and a resistance wire heating layer 13 fixedly connected to the inner wall of the first tube body. The resistance wire heating layer 13 is provided with a control unit which is electrically connected to the control box 1. The inner diameter of the first tube body is the same at all places.

[0043] The expanded tube 7 includes a second tube body 15 and a third tube body 17 fixedly connected to the second tube body 15. The free end of the third tube body 17 is provided with a connecting ring 18, and the connecting ring 18 is installed on the inner wall of the first tube body. The inner diameter of the third tube body 17 gradually decreases along the direction of the second tube body 15, and the smallest inner diameter of the third tube body 17 is equal to the inner diameter of the second tube body 15.

[0044] Specifically: the inner wall of the second tube body 15 is provided with a plurality of roller 14 grooves, in which a plurality of rollers 14 are rotatably connected, and the rollers 14 are in the same direction as the axis of the second tube body, and an end of the second tube body 15 away from the third tube body 17 is provided with a flaring group 19 for pressure relief;

[0045] About flaring group 19:

[0046] The expansion group 19 includes a connecting ring 1901 arranged at the end of the second tube body 15, a plurality of notch plates 1902 rotatably connected to the connecting ring 1901, and an elastic shrinkage rope 1903 arranged between adjacent notch plates 1902. When the notch plates 1902 are not unfolded, the notch plates 1902 are combined to form a first notch 1904. When the notch plates 1902 are unfolded, the notch plates 1902 are combined to form a second notch.

[0047] First, the heating tube 8 is used to heat the gas 16. The heating tube 8 is used to heat the pipeline. By heating the gas 16, the thermal motion of the gas 16 molecules can be increased, the kinetic energy thereof can be increased, and the flow rate can be increased. The faster the flow rate, the smaller the pressure, and the more obvious the negative pressure effect is, thereby improving the negative pressure effect.

[0048] Then the gas 16 enters the third tube body 17. Since the inner diameter of the third tube body 17 gradually decreases along the direction of the second tube body 15, the flow channel becomes narrower, which can accelerate the gas 16 when passing through. The faster the flow rate, the lower the pressure, and the more obvious the negative pressure effect is, thereby improving the negative pressure effect.

[0049] Then it reaches the second tube body 15 from the third tube body 17. Since the notch plate 1902 is not unfolded when just entering, the size of the first notch 1904 is small, and the gas 16 flows slowly. The air pressure inside the second tube body 15 begins to gradually increase. The greater the resistance encountered by the gas 16 when passing through, when it increases to a limited value, the expansion group 19 opens, the outlet diameter becomes larger instantly, and after the pressure of the gas 16 is increased, the air pressure begins to drop instantly, and the flow rate begins to increase rapidly. The faster the flow rate, the smaller the pressure, and the more obvious the negative pressure effect is, thereby improving the negative pressure effect.

[0050] Through the improvement of the above structure, the negative pressure effect of the device is comprehensively improved, thereby improving the dust collection effect, and thus the device solves the problem of difficult dust handling in the traditional fine cutting process.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
