[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Example 1, by Figure 1 and Figure 2 The present invention provides a dust collection device for cutting a spiral press rod, comprising a dust collection mechanism 1 connected to one end of a sealed cutting box 2. The sealed cutting box 2 contains a press rod cutting assembly 3, and a sliding door 4 is provided on the front of the sealed cutting box 2. The dust collection mechanism 1 consists of a dust collection hood 5, a dust collection fan 6, a flow guide 7, a dust removal assembly 8, and an exhaust pipe 9. The dust collection hood 5 is fixedly connected to the top of the sealed cutting box 2. The dust collection fan 6 is located at one end of the sealed cutting box 2 and connected to the dust collection hood 5. The flow guide 7 is fixedly connected between the dust collection fan 6 and the dust removal assembly 8. The exhaust pipe 9 is fixedly connected to the top of the dust removal assembly 8.

[0034] In use, the dust hood 5 is connected to the sealed cutting box 2, and the dust is vacuumed by the dust fan 6 and the dust hood 5. The dust is discharged into the dust removal component 8, and the dust is filtered and removed by the dust removal component 8.

[0035] Example 2, based on Example 1, is... Figure 2 and Figure 3 The dust removal assembly 8 is composed of a dust collection box 10, an electrostatic dust removal unit 11, a pulse blower 12, several bag filters 13, several dust collection units 14, and several sealing and guiding integrated components 15. Several support legs 16 are fixedly installed on the side of the bottom end of the dust collection box 10, and a support plate 17 is fixedly installed on the top of one side of the dust collection box 10. The pulse blower 12 is fixedly connected to the top of the support plate 17. The electrostatic dust removal unit 11 is connected to the top of one end of the dust collection box 10 and passes through the dust collection box 10. The bag filters 13 are fixedly connected to the top of the other end of the dust collection box 10 and are connected in cooperation with the pulse blower 12. The dust collection units 14 are fixedly connected to the bottom end of the dust collection box 10, and the sealing and guiding integrated components 15 are connected to the bottom end of the dust collection box 10 and pass through the dust collection units 14.

[0036] When the dust removal component 8 is working, it first removes dust through the electrostatic dust removal unit 11, and then through the bag filter 13, which effectively improves the dust removal efficiency. The pulse fan 12 can supply air to the bag filter 13 and the sealing and guiding integrated component 15. The dust is cleaned by back-blowing the bag filter 13 with gas. The dust is collected by the dust collection unit 14 and discharged by the sealing and guiding integrated component 15. At the same time, the dust discharge port can be sealed to prevent gas leakage.

[0037] Example 3, based on Example 1, is... Figures 2 to 5 As shown, the electrostatic dust removal unit 11 consists of an electrostatic dust collection plate 18 and an electromagnetic vibration structure 19. The electromagnetic vibration structure 19 is fixedly connected to one end of the top of the dust collection box 10 and slides through the dust collection box 10. The electrostatic dust collection plate 18 is located inside the dust collection box 10 and is fixedly connected to the bottom end of the electromagnetic vibration structure 19. The electromagnetic vibration structure 19 consists of a mounting sleeve 20, a limiting rod 21, a limiting sliding sleeve 22, a spring 23, an electromagnet 24, and a permanent magnet 25. The mounting sleeve 20 is fixedly connected to the top of the dust collection box 10, and the limiting sliding sleeve 22 is fixedly connected to the mounting sleeve 25. Inside the bottom of the mounting sleeve 20, the limiting rod 21 slides through the limiting sleeve 22, the spring 23 is sleeved on the limiting rod 21, the electromagnet 24 is fixedly connected to the top of the limiting rod 21, the permanent magnet 25 is movably connected to the top of the mounting sleeve 20, the top of the electromagnet 24 is fixedly provided with an anti-collision rubber pad 26, the top of the side inside the mounting sleeve 20 is provided with several vertical limiting grooves 27, the top of the permanent magnet 25 is fixedly provided with a counterweight 28, and the side of the counterweight 28 is fixedly provided with a vertical limiting slider 29 that slides through the vertical limiting groove 27;

[0038] When the electrostatic dust removal unit 11 is working, it absorbs dust through the electrostatic dust collection plate 18. When there is a lot of dust on the surface of the electrostatic dust collection plate 18, the electrostatic dust collection plate 18 is de-energized. At this time, the electromagnetic vibration structure 19 is activated, which drives the electrostatic dust collection plate 18 to vibrate up and down, thereby quickly shaking off the dust on the surface of the electrostatic dust collection plate 18 and preventing the dust collection effect of the electrostatic dust collection plate 18 from being affected by too much dust. When the electromagnetic vibration structure 19 is working, the electromagnet 24 is energized. The electromagnet 24 and the permanent magnet 25 have the same magnetic poles, so they can pass through... The electromagnet 24 pushes the permanent magnet 25 upward. When the permanent magnet 25 reaches the top, the electromagnet 24 is de-energized, and the permanent magnet 25 falls due to gravity, thereby driving the limiting rod 21 to fall. The spring 23 can buffer the permanent magnet 25, thus forming multiple oscillations. Continuous multiple oscillations can quickly shake off the dust on the surface of the electrostatic dust collection plate 18. The counterweight 28 can increase the potential energy of the permanent magnet 25 when it falls. The vertical limiting groove 27 and the vertical limiting slider 29 can limit the permanent magnet 25 and improve stability.

[0039] Example 4, based on Example 1, is... Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a pulse exhaust pipe 30 is fixedly installed at the outlet of the pulse blower 12. Several pulse exhaust branch pipes 31, which pass through the dust collector 10 and connect to the bag filter 13, are fixedly installed at the bottom end of the pulse exhaust pipe 30. A solenoid valve 32 is installed on each pulse exhaust branch pipe 31. The bag filter 13 consists of a metal mesh frame 33 and filter bags 34. The filter bags 34 are fitted onto the arc-shaped outer surface of the metal mesh frame 33. The top and bottom ends of the metal mesh frame 33 are sealed. An exhaust port 35 is opened at the bottom end of the metal mesh frame 33. The top end of the bag filter 13 is connected to the exhaust pipe... 9. A dustproof housing 36 is fixedly installed at the bottom of the dust collector 10. The integrated sealing and guiding component 15 is connected to the bottom of the dustproof housing 36 and passes through the dustproof housing 36 and the dust collection unit 14. A pulse exhaust pipe 37 is fixedly installed at one end of the bottom of the pulse exhaust pipe 30, passing through the dustproof housing 36 and connected to the integrated sealing and guiding component 15. The dustproof housing 36 and the metal mesh frame 33 are connected by an air supply pipe 38. The top end of the air supply pipe 38 is fixedly connected to the exhaust port 35. The integrated sealing and guiding component 15 consists of an airtight sleeve 39, a motor sleeve 40, and a servo motor 4. 1. The device comprises a rotating shaft 42, a sealing head 43, a spiral feed rod 44, a counterweight ball 45, an anti-collision pad 46, a pulse exhaust branch pipe 47, and a solenoid valve 48. An airtight sleeve 39 is fixedly connected to the inside of the dustproof housing 36. A motor sleeve 40 is slidably connected to the inside of the airtight sleeve 39. A servo motor 41 is fixedly connected to the inside of the motor sleeve 40. The rotating shaft 42 is fixedly connected to the output shaft of the servo motor 41 and slidably inserted into the airtight sleeve 39. The sealing head 43 is sleeved on the rotating shaft 42. The spiral feed rod 44 is fixedly connected to the bottom end of the rotating shaft 42. The counterweight ball 45 is fixedly connected to the spiral feed rod. At the bottom end of rod 44, anti-collision pad 46 is fixedly connected to the top end inside airtight sleeve 39. Pulse exhaust branch pipe 2 47 is fixedly connected between airtight sleeve 39 and pulse exhaust pipe 2 37. Solenoid valve 2 48 is connected to pulse exhaust branch pipe 2 47. Dust collection unit 14 consists of first dust collection box 49, narrow-mouth guide sleeve 50 and second dust collection box 51. First dust collection box 49 is fixedly connected to the bottom end of dust collection box 10. Second dust collection box 51 is fixedly connected to the bottom end of first dust collection box 49 through narrow-mouth guide sleeve 50. Narrow-mouth guide sleeve 50 is matched with sealing head 43 and spiral feed rod 44.

[0040] When the bag filter 13 is working, dust remains on the outer surface of the filter bag 34. Gas penetrates the filter bag 34 and is then discharged through the filter bag 34 into the interior of the exhaust pipe 9. Clean gas is discharged through the exhaust pipe 9. When there is a lot of dust on the surface of the filter bag 34, the pulse blower 12 is started and the corresponding solenoid valve 32 is opened. Pulse gas enters the interior of the bag filter 13 through the pulse exhaust branch pipe 31. The pulse airflow back-blown the filter bag 34, causing the filter bag 34 to bulge from top to bottom and blow off the dust, preventing the dust from becoming too concentrated. Excessive dust accumulation can negatively impact dust removal efficiency. During normal dust removal operation, the dust collection unit 14 is sealed using the integrated sealing and guiding component 15 to prevent gas leakage. When a large amount of dust is collected inside the dust collection unit 14, the integrated sealing and guiding component 15 is used to open the dust collection unit 14 and assist in dust removal. When the integrated sealing and guiding component 15 is working, the corresponding solenoid valve 48 is opened, and air is supplied to the inside of the airtight sleeve 39 through the pulse exhaust branch pipe 47. The motor sleeve 40 rises under the thrust of the gas, thereby driving the servo motor. 41. The rotating shaft 42, sealing head 43, spiral feeder 44, and counterweight ball 45 rise synchronously. At this time, the sealing head 43 separates from the narrow-mouth guide sleeve 50, and the spiral feeder 44 is located in the middle position of the narrow-mouth guide sleeve 50. The servo motor 41 is started, which drives the rotating shaft 42 to rotate, thereby driving the spiral feeder 44 to rotate, facilitating the entry of dust into the interior of the second dust collection box 51. After the dust discharge is completed, the second solenoid valve 48 closes, and the motor sleeve 40, servo motor 41, rotating shaft 42, sealing head 43, spiral feeder 44, and counterweight ball 45 rise synchronously. The ball 45 moves downwards due to its own weight. At this time, the sealing head 43 seals the narrow-mouth guide sleeve 50 to prevent gas leakage. Meanwhile, the dustproof housing 36 and the metal mesh frame 33 are connected by the air supply pipe 38. Therefore, part of the clean gas filtered by the dust bag 34 will enter the interior of the dustproof housing 36, making the interior of the dustproof housing 36 positive pressure. This prevents dust from entering the interior of the dustproof housing 36 through gaps and avoids dust affecting the normal operation of the airtight sleeve 39, motor sleeve 40, servo motor 41 and rotating shaft 42.

[0041] During operation, a dust collection mechanism consisting of a dust hood, dust fan, air guide, dust removal components, and exhaust pipe is used to absorb dust inside the sealed cutting box. This prevents dust from affecting the normal operation of the press rod cutting components and also protects the health of the workers. A dust removal component consisting of a dust collection box, electrostatic precipitator, pulse fan, several bag filters, several dust collection units, and several integrated sealing and air guiding components enables dust removal. An electrostatic dust collection plate utilizes the principle of electrostatic dust collection for dust removal. An electromagnetic vibration structure consisting of a mounting sleeve, limit rod, limit sliding sleeve, spring, electromagnet, and permanent magnet drives the electrostatic dust collection plate to vibrate, thereby removing dust adsorbed on its surface and preventing excessive dust from affecting the dust removal effect. By setting up a bag filter consisting of a metal mesh frame and filter bags, dust removal operations can be further improved. Equipped with a pulse blower, a pulse exhaust pipe, a pulse exhaust branch pipe, and a solenoid valve, the pulse airflow can be used to back-blow and clean the dust adhering to the surface of the filter bags, preventing excessive dust accumulation that could affect dust removal operations. This eliminates the need for manual dust cleaning, improving dust removal efficiency. Furthermore, by setting up an integrated sealing and guiding assembly consisting of an airtight sleeve, a motor sleeve, a servo motor, a rotating shaft, a sealing head, a spiral feed rod, a counterweight ball, anti-collision pads, a second pulse exhaust branch pipe, and a second solenoid valve, along with a dust collection unit consisting of a first dust collection box, a narrow-mouth guide sleeve, and a second dust collection box, dust discharge and collection operations can be achieved, effectively improving the smoothness of dust discharge. Simultaneously, during normal dust removal, the dust collection unit can be sealed to prevent gas leakage.
