Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0035] Reference Figure 1 - Figure 3This utility model provides an embodiment of an automatic collection and treatment device for volatile waste gas from printing, comprising a body 1. The body 1 is the core space for waste gas collection, filtration, and treatment, providing an installation carrier for replacement components 2, sealing components 3, and locking components 4, while simultaneously enabling orderly flow of waste gas within the body and preventing premature leakage. A base plate 8 is fixedly connected to the lower surface of the body 1, providing stable support for the body 1, ensuring the overall balance of the device, and serving as an installation platform for the high-pressure pump 217. Replacement components 2 are provided on the inner wall of the body 1, enabling safe replacement of the filter box 5. Sealing components 3 are provided on the upper surface of the body 1, preventing waste gas leakage. Two sets of locking components 4 are provided on the inner wall of the body 1; one set is used to lock or unlock the baffle 22, and the other set is used to lock or unlock... The filter box 5 is locked. The replacement component 2 includes a partition plate 21, which is used to limit the sliding trajectory of the baffle 22. The partition plate 21 is fixedly connected to the inner wall of the body 1. The baffle 22 is slidably connected to the inner wall of the partition plate 21. The baffle 22 is used to cooperate with the partition plate 21 to block the exhaust gas from rising. The left and right sides of the inner wall of the body 1 are slidably connected to the first sliding block 24. The first sliding block 24 is a transmission component between the baffle 22 and the pressure block 212. It is used to link and start the high-pressure pump 217 to reduce manual operation. The left and right ends of the first sliding block 24 are fixedly connected to the first limiting block 25. The first limiting block 25 is used to limit the sliding range of the first sliding block 24 and prevent the first sliding block 24 from falling off the inner wall of the body 1. The first limiting block 25 is elastically connected to the inner wall of the body 1 through the first spring 26. The first spring 26 is used to provide elastic reset capability.

[0036] Reference Figure 1 - Figure 3An exhaust pipe 27 is fixedly connected through the inner wall of the machine body 1. The exhaust pipe 27 is the channel for the high-pressure pump 217 to extract exhaust gas from the inside of the machine body 1. A limit groove 211 is provided at the front end of the first sliding block 24. The limit groove 211 is used to drive the pressure block 212 to move downward through the baffle 22. The pressure block 212 is fixedly connected to the end of the first sliding block 24 near the center of the rear end of the machine body 1. The pressure block 212 is used to convert the linear motion of the first sliding block 24 into the movement of the rack 213. A rack 213 is provided at the left end of the pressure block 212. The rack 213 is used to move the pressure block... The linear movement of rack 212 is converted into the rotational motion of the first gear 215, realizing the power transmission of the mechanical transmission. A first limiting rod 214 is provided on the inner wall of the machine body 1, and the first gear 215 is rotatably connected to the outer wall of the first limiting rod 214. The first gear 215 is used to realize the power transmission between rack 213 and the second gear 216, converting the linear motion of rack 213 into the rotational motion of the second gear 216, thereby driving the rotary knob 219 to rotate and triggering the high-pressure pump 217 to start. The high-pressure pump 217 is installed on the upper surface of the base plate 8. 217 is used to extract untreated exhaust gas from the machine body 1 through the extraction pipe 27 after startup, and then send the exhaust gas back to the filter area of ​​the machine body 1 through the outlet pipe 220, so that a negative pressure or exhaust gas residue is formed in the machine body 1, avoiding exhaust gas leakage when replacing the filter box 5. The upper surface of the high-pressure pump 217 is equipped with a control system 218. When the rotary knob 219 is driven to rotate by the second gear 216, the control system 218 receives mechanical signals and converts them into electrical signals to control the high-pressure pump 217 to start or stop. At the same time, the rotary knob 219 can be manually adjusted. The high-pressure pump 217 can be manually controlled. The inner wall of the control system 218 is rotatably connected to a rotary knob 219. The rotary knob 219 is used to drive the high-pressure pump 217 to rotate through the second gear 216, triggering the automatic start of the high-pressure pump 217. The front end of the rotary knob 219 is provided with the second gear 216, which is used to transmit the rotational motion of the first gear 215 to the rotary knob 219. The right end of the high-pressure pump 217 is fixedly connected to the exhaust pipe 220, which is used to send the exhaust gas drawn by the high-pressure pump 217 back into the machine body 1.

[0037] Reference Figure 4 - Figure 6The baffle 22 has a handle groove 23 at its front end, which is used to facilitate the operator to remove or push the baffle 22 forward. The inner wall of the partition plate 21 has multiple sets of first vent holes 28, which cooperate with second vent holes 29 to block the ventilation channel or ensure smooth entry of exhaust gas into the filtration area. The inner wall of the baffle 22 also has multiple sets of second vent holes 29, which cooperate with the first vent holes 28. To block the ventilation channel or ensure smooth entry of exhaust gas into the filtration area, a baffle 22 is inserted into the inner wall of the limiting groove 211. A first gear 215 meshes with a rack 213, and a second gear 216 meshes with the first gear 215. The lower end of the suction pipe 27 is fixedly connected to the upper surface of the high-pressure pump 217. The other end of the exhaust pipe 220 passes through and is fixedly connected to the inner wall of the body 1. A pressure block 212 is slidably connected to the inner wall of the body 1. The sealing assembly 3 includes an exhaust port 31, which is the outlet for filtered clean gas. The exhaust port 31 is fixedly connected to the upper surface of the body 1. A second limiting rod 32 is slidably connected to the inner wall of the exhaust port 31. The second limiting rod 32 provides a lifting guide for the exhaust cover 36, limiting the direction of movement of the exhaust cover 36. The second limiting rod 32 is elastically connected to the inner wall of the exhaust port 31 via a second spring 33, which provides elastic reset capability. The upper surface of the second limiting rod 32 is fixed... An exhaust cover 36 is connected to the machine body 1. The exhaust cover 36 is used to move down and close the exhaust port 31 under negative pressure to prevent untreated waste gas from leaking from the exhaust port 31. A fixing block 34 is fixedly connected to the lower end of the exhaust cover 36. The fixing block 34 is used to transfer the negative pressure suction force received by the conical block 35 to the exhaust cover 36, causing the exhaust cover 36 to move down and close the exhaust port 31. A conical block 35 is fixedly connected to the lower surface of the fixing block 34. The conical block 35 is used to increase the negative pressure area.

[0038] Reference Figure 7 - Figure 8The locking assembly 4 includes a second sliding block 42, which is used to lock the baffle 22 and prevent it from moving accidentally. The second sliding block 42 is slidably connected to the inner wall of the body 1. An operating block 41 is fixedly connected to the front end of the second sliding block 42. The operating block 41 is used to lock or unlock the baffle 22. Another set is used to lock or unlock the filter box 5. Second limiting blocks 44 are fixedly connected to both the left and right ends of the second sliding block 42. The second limiting blocks 44 are used to limit the sliding range of the second sliding block 42. The second limiting blocks 44 are elastically connected to the inner wall of the body 1 through a third spring 43, which provides elastic reset capability. A support block 11 is provided on the inner wall of the body 1. The support block 11 is used to provide a sliding support track for the filter box 5. A filter box 5 is slidably connected to the upper surface of block 11. The filter box 5 is used to install or replace internal filter items. A filter plate 6 is inserted into the inner wall of the filter box 5. The filter plate 6 is used to fix the filter items to the inner wall of the filter box 5. A handle 7 is provided at the front end of the filter box 5. The handle 7 is used to facilitate the operator to pull out the filter box 5 and replace it. A support leg 10 is fixedly connected to the lower surface of the base plate 8. The support leg 10 is used to prevent the base plate 8 from directly contacting the ground and to prevent ground moisture and debris from corroding the base plate 8 and internal components. An air inlet 9 is provided through the lower surface of the base plate 8. The air inlet 9 is used to allow exhaust gas to enter the interior of the machine body 1. The air inlet 9 is provided through the inner wall of the machine body 1. The rear end of the baffle 22 is set with an inclined structure. The inner wall of the limiting groove 211 is set with an inclined structure.

[0039] Working principle: When the filter material in the filter box 5 becomes saturated and needs to be replaced, the operator pulls the operating block 41 of the locking assembly 4 outward, causing the second sliding block 42 to move against the elastic force of the third spring 43, releasing the lock on the baffle 22. Subsequently, the baffle 22 is pushed forward through the handle groove 23 at the front end of the baffle 22. The baffle 22 continues to move forward until the first vent 28 and the second vent 29 are completely misaligned, and the partition plate 21 forms a closed barrier. Since the rear end of the baffle 22 is inclined and the inner wall of the limiting groove 211 at the front end of the first sliding block 24 is inclined, the first sliding block 24 can be pushed along the machine. When the inner wall of body 1 slides downward, the first sliding block 24 moves downward, and the first limiting blocks 25 at its left and right ends compress the first spring 26, which at the same time drives the fixedly connected pressure block 212 to slide downward synchronously. The rack 213 at the left end of the pressure block 212 moves with the pressure block 212 and meshes with the first gear 215 on the first limiting rod 214 on the inner wall of body 1. The first gear 215 then meshes with the second gear 216 at the front end of the rotary knob 219, driving the rotary knob 219 to rotate. The control system 218 receives the mechanical rotation signal of the rotary knob 219, converts it into an electrical signal, and triggers the high-pressure pump 217 installed on the base plate 8 to start.

[0040] After the high-pressure pump 217 is started, the exhaust pipe 27, which is fixed through the inner wall of the machine body 1, extracts the residual untreated exhaust gas inside the machine body 1. The extracted exhaust gas is sent back to the filter area of ​​the machine body 1 through the exhaust pipe 220 at the right end of the high-pressure pump 217. This can create a temporary negative pressure environment inside the machine body 1. The conical block 35 drives the exhaust cover 36 to move down against the elastic force of the second spring 33 through the fixed block 34 until the exhaust cover 36 completely covers the exhaust port 31, sealing the discharge channel and preventing untreated exhaust gas from leaking from the exhaust port 31. This also blocks the airflow exchange between the filter area and the air intake area, further preventing the spread of exhaust gas. The operator releases the locking component 4 from the filter box 5 and pulls it out along the support block 11 through the handle 7 at the front end of the filter box 5.

[0041] After replacing the internal filter material and filter plate 6, push the filter box 5 back to its original position. The second sliding block 42 of the locking assembly 4 automatically resets under the elastic force of the third spring 43, relocking the filter box 5. Then, pull the baffle 22 in the opposite direction. The first sliding block 24 moves upward under the elastic reset force of the first spring 26, driving the rack 213 and gear set to reverse transmission. Rotate the knob 219 to reset. The control system 218 controls the high-pressure pump 217 to stop working. The negative pressure inside the machine body 1 disappears. The vent cover 36 moves upward under the action of the second spring 33 to open the vent 31. The baffle 22 resets to the state of aligning the vent holes. The locking assembly 4 relocks the baffle 22, and the device returns to normal exhaust gas treatment mode.
