Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and more specifically to a laser printing equipment with a smoke emission device. Background Technology

[0002] Laser marking machines use laser beams to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, thus creating exquisite patterns, trademarks, and text. Existing garment processing also uses laser marking machines to print on clothing.

[0003] Existing laser marking machines generate a large amount of smoke when the laser comes into contact with clothing and evaporates the surface material. This smoke contains small solid particles of the surface material. If the smoke is not treated, it will leave a lingering odor on the clothing. Furthermore, when the smoke is extracted and discharged, the solid particles are released into the atmosphere, causing air pollution. For example, Chinese patent (authorization announcement number CN217942209U) discloses laser printing equipment for garment processing; please refer to the specification attached to that patent. Figure 2 and 4 A connecting pipe 6 is installed on the straight section 301. The connecting pipe 6 is used to connect the parallel straight sections 301. By connecting the parallel straight sections 301 through the connecting pipe 6, the water in the upper straight section 301 can be guided downward through the connecting pipe 6 to continue to contact the solid particles in the gas, thereby increasing the utilization rate of the water flow.

[0004] In the aforementioned patent, dirt will remain on the inner wall of the connecting pipe 6 over time and will be difficult to clean, causing blockage. Therefore, it is necessary to improve the structure. Utility Model Content

[0005] The purpose of this utility model is to provide a laser printing equipment with a smoke emission device in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A laser printing device with a smoke emission device includes a laser marking machine, which includes a conveyor belt for moving garments, and also includes an air inlet pipe, an air outlet pipe and a filter box connected in sequence.

[0008] The bottom of the air inlet duct is equipped with several air inlets facing the conveyor belt;

[0009] An exhaust fan is installed on the air supply duct. The exhaust fan is used to direct the air in the air inlet duct to the air supply duct.

[0010] The filter box includes a box body and a top cover on the box body. Side plates are provided on both sides of the top cover, and a partition is provided in the middle of the top cover. Several baffles are provided on both the side plates and the partition, and the baffles are arranged at intervals from top to bottom to form an S-shaped curved space.

[0011] The left side panel of the top cover is connected to the air supply pipe, and the air outlet is located on the side of the box away from the air supply pipe. The right side panel of the top cover is connected to the air outlet.

[0012] The top of the enclosure is equipped with a sealing ring. The sealing ring increases the airtightness between the enclosure and the top cover.

[0013] The top cover is connected to the housing at its four corners via sealing screws. These screws facilitate the disassembly and separation of the top cover from the housing while ensuring a tight seal during connection to prevent gas leakage.

[0014] The laser marking machine also includes a water spraying component, which consists of a vertical pipe and a horizontal pipe. The vertical pipe is fixedly inserted into the top cover, and the horizontal pipe is fixedly connected to the inner wall of the top cover. The upper end of the vertical pipe is connected to a water source, and the lower end of the vertical pipe is connected to the horizontal pipe. Two atomizing nozzles are provided at the bottom of the horizontal pipe. The atomizing nozzles spray the water in the horizontal pipe in a mist form. The atomizing nozzles are purchased from the market. By setting up the water spraying component, solid particles in the gas are settled, reducing the content of solid particles in the exhaust gas flow and reducing air pollution.

[0015] The baffle is inclined downwards, and its surface has a groove. A row of fine grooves is located on the lower side of the baffle, with one end of each groove connected to the outside and the other end connected to the groove. This row of fine grooves creates a water curtain as water falls along the baffle, improving the atomization effect of the solid particles.

[0016] The bottom of the box is equipped with a drain outlet.

[0017] Working principle: When the exhaust fan is working, it draws smoke into the air inlet pipe through the air inlet, and then sends it into the chamber through the air outlet pipe. The partition divides the chamber into two spaces with the bottom connected, making the chamber a U-shaped space. The gas enters the chamber and first flows downward, and then flows upward through the bottom bend. By setting baffles, S-shaped curved spaces are formed on both sides of the chamber, which increases the residence time of the gas and improves the settling effect of solid particles.

[0018] By setting up water spray components to settle solid particles in the gas, water flows into the baffle under the action of gravity, and by setting up fine channels, the water flow forms a water curtain, which causes the solid particles to settle again, increasing the settling effect. The water containing solid particles is stored at the bottom of the tank under the action of gravity, and the water in the tank is discharged through the drain outlet.

[0019] In this invention, the top cover can be removed from the box body to clean the inside of the box and the baffles. Disassembly is convenient, cleaning efficiency is high, and the service life of the equipment is extended.

[0020] In this invention, the partition is a certain distance from the bottom of the box so that the two sides of the partition are connected.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention replaces the connecting pipe in the prior art by setting baffles to form an S-shaped curved space, which has a better solid particle settling effect. In addition, the top cover and the box can be quickly disassembled and separated, which facilitates the cleaning of dirt in the later stage, avoids blockage, and extends the service life of the equipment.

It also includes an air inlet pipe 2, an air outlet pipe 3, and a filter box 4 connected in sequence.

[0032] The bottom of the air inlet pipe 2 is provided with several air inlets 5 facing the conveyor belt 1;

[0033] An exhaust fan 6 is installed on the air supply duct 3. The exhaust fan 6 is used to direct the air in the air inlet duct 2 into the air supply duct 3.

[0034] The filter box 4 includes a box body 7 and a top cover 8 on the box body 7. Side plates 9 are provided on both sides of the top cover 8, and a partition 10 is provided in the middle of the top cover 8. Several baffles 11 are provided on both the side plates 9 and the partition 10. The baffles 11 are arranged at intervals from top to bottom to form an S-shaped curved space 12.

[0035] The side panel 9 on the left side of the top cover 8 is connected to the air supply pipe 3. An air outlet 13 is provided on the side of the box body 7 away from the air supply pipe 3. The side panel 9 on the right side of the top cover 8 is connected to the air outlet 13.

[0036] The top of the housing 7 is provided with a sealing ring 14. The sealing ring 14 is used to increase the airtightness between the housing 7 and the top cover 8.

[0037] The top cover 8 is connected to the housing 7 at its four corners via sealing screws. The sealing screws facilitate the disassembly and separation of the top cover 8 from the housing 7 while ensuring a tight seal during connection to prevent gas leakage.

[0038] The laser marking machine also includes a water spraying component, which comprises a vertical pipe 15 and a horizontal pipe 16. The vertical pipe 15 is fixedly inserted into the top cover 8, and the horizontal pipe 16 is fixedly connected to the inner wall of the top cover 8. The upper end of the vertical pipe 15 is connected to a water source, and the lower end of the vertical pipe 15 is connected to the horizontal pipe 16. Two atomizing nozzles 17 are provided at the bottom of the horizontal pipe 16. The atomizing nozzles 17 spray the water in the horizontal pipe 16 into a mist. The atomizing nozzles 17 are purchased from the market. By setting up the water spraying component, solid particles in the gas are settled, reducing the content of solid particles in the exhaust gas flow and reducing air pollution.

[0039] The baffle 11 is inclined downwards, and its surface has a groove 18. A row of fine grooves 19 is provided on the lower side of the baffle 11. One end of the fine grooves 19 is connected to the outside, and the other end is connected to the groove 18.

[0040] The bottom of the box 7 is provided with a drain outlet 20.

[0041] Working principle: When the exhaust fan 6 is working, it draws the smoke into the air inlet pipe 2 through the air inlet 5, and then sends it into the casing 7 through the air supply pipe 3. The partition 10 divides the casing 7 into two spaces with the bottom connected, making the casing 7 a U-shaped space. The gas enters the casing 7 and first flows downward, and then flows upward through the bottom bend. By setting the baffle 11, S-shaped curved spaces 12 are formed on both sides of the casing 7, which increases the residence time of the gas and improves the settling effect of solid particles.

[0042] By setting up water spray components to settle solid particles in the gas, water flows into the baffle 11 under the action of gravity. By setting up the fine groove 19, the water flow forms a water curtain, which causes the solid particles to settle a second time, increasing the settling effect. The water containing solid particles is stored at the bottom of the box 7 under the action of gravity, and the water in the box 7 is discharged through the drain outlet 20.

[0043] In this invention, the top cover 8 can be removed from the housing 7 to clean the inside of the housing 7 and the baffle 11. This makes disassembly convenient, cleaning efficient, and extends the service life of the equipment.

[0044] In this utility model, the partition 10 is a certain distance from the bottom of the box 7 so that the two sides of the partition 10 are connected.
