[0003] The basic materials of lithium batteries include positive and negative electrode sheets. Before the winding process, the electrode sheets need to be die-cut to achieve the required width. This die-cutting process often generates waste, which is scattered on the workshop floor, affecting cleanliness and posing safety hazards, thus requiring cleanup. Current waste collection devices only collect the waste, leading to frequent handling of full waste bins by operators, thereby impacting production efficiency. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figure 1 As shown, a waste compressor includes a waste frame 1, a discharge bin 2, a waste compression mechanism 4, and a negative pressure dust collection mechanism 3. The discharge bin 2 and the negative pressure dust collection mechanism 3 are installed in the waste frame 1. The waste compression mechanism 4 is detachably mounted on the waste frame 1 to facilitate disassembly for maintenance and replacement. The negative pressure dust collection mechanism 3 is installed on one side of the discharge bin 2, and the waste compression mechanism 4 is installed at the lower end of the discharge bin 2. The discharge bin 2 includes a discharge chamber 23, a feeding structure 21, and a discharge port 22. The feeding structure 21 is installed in the discharge chamber 23. At the upper end, the discharge port 22 is located at the lower end of the discharge chamber 23. The waste compression structure 4 is connected to the lower end of the discharge chamber 23 through the discharge port 22. The negative pressure dust collection mechanism 3 is connected to the upper end of the discharge chamber 23. The negative pressure dust collection mechanism 3 generates negative pressure to adsorb dust and waste through the feeding structure 21 into the discharge chamber 23. The negative pressure dust collection mechanism 3 adsorbs and collects dust from the discharge chamber 23. The waste passes through the discharge chamber 23 and falls into the waste compression mechanism 4. The waste compression mechanism 4 compresses and collects the waste, thereby realizing automatic waste collection and preventing dust overflow.

[0024] Please continue to refer to this. Figure 1As shown, the feeding structure 21 includes a feed inlet 211, a filter screen 212, and a pulse blowing structure 213. The feed inlet 211 connects the discharge chamber 23 to the outside of the waste collection frame 1. The feed inlet 211 uses negative pressure to adsorb dust and waste into the discharge chamber 23. The filter screen 212 is installed at the upper end of the discharge chamber 23, and the feed inlet 211 passes through the filter screen 213 to separate dust and waste. The filter screen 212 will block the waste from moving upward, allowing the waste to pass through. The material enters the waste compression mechanism 4 through the discharge chamber 23. Dust passes through the filter screen 212 and is collected by the negative pressure dust collection mechanism 3. The pulse blowing structure 213 is installed on the top of the discharge chamber 23. The pulse inflation structure 213 blows air into the discharge chamber 23 periodically through the pulse valve to prevent the discharge chamber 23 from being blocked. The cross-section of the discharge chamber 23 has an alternating rectangular and trapezoidal structure, which is used to guide the waste into the waste compression mechanism 4 and to buffer the waste.

[0025] Please combine Figure 1-4 As shown, the negative pressure dust collection mechanism 3 includes a dust collection pipe 35, a dust collection box 31, a primary filter assembly 32, a secondary filter assembly 33, and a dust collection fan 34. The primary filter assembly 32 is installed on the upper end of the dust collection box 31, the secondary filter assembly 33 is installed on the upper end of the primary filter assembly 32, and the dust collection fan 34 is installed on the upper end of the secondary filter assembly 33. The primary filter assembly 32 is connected to the upper end of the discharge chamber 23 through the dust collection pipe 35. The dust collection box 31, the primary filter assembly 32, and the secondary filter assembly 33 are detachably mounted on the waste material frame 1 to facilitate replacement of the filter structure and cleaning of dust. The primary filter assembly 32 is used to filter large dust particles, causing them to fall into the dust collection box 31. The secondary filter assembly 33 is used to filter small dust particles. The dust collection fan 34 is used to generate negative pressure, and the filtered air is directly discharged outside the waste material frame 1. The dust collection box 31 is a pull-out type dust collection box to facilitate the collection and disposal of large dust particles.

[0026] The second filter assembly 33 includes a second filter chamber 331 and a secondary filter screen 332. The secondary filter screen 332 is installed at the upper end of the second filter chamber 331 and close to the dust collection fan 34. The secondary filter screen 332 is used to adsorb small particulate dust and prevent small particulate dust from being discharged to the outside by the dust collection fan 34.

[0027] The first filter assembly 32 includes a spiral pulse assembly 323, a first filter chamber 321, a filter cartridge 322, and a differential pressure alarm system (not shown in the figure). The first filter chamber 321 is connected to the dust collection box 31. The first filter chamber 321 is connected to the second filter chamber 331 through the filter cartridge 322. The spiral pulse assembly 323 is installed in the second filter chamber 331 and aligned with the filter cartridge 322. The filter cartridge 322 is used to filter large dust particles. The spiral pulse assembly 323 periodically blows positive pressure gas from the gas storage tank into the filter cartridge 322 to blow away the dust adhering to the filter cartridge 322, thereby achieving the effect of cleaning the filter cartridge 322. The differential pressure alarm system includes a first differential pressure sensor and a second differential pressure sensor. The first differential pressure sensor is installed in the first filter chamber 321, and the second differential pressure sensor is installed in the second filter chamber 331. The first differential pressure sensor detects the differential pressure P1 in the first filter chamber 321, and the second differential pressure sensor detects the differential pressure P2 in the second filter chamber 331. The system compares the set differential pressure value ΔP with the difference between the differential pressure P1 in the first filter chamber 321 and the differential pressure P2 in the second filter chamber 331. When ΔP ≥ |P1-P2|, the negative pressure dust collection mechanism 3 operates normally; when ΔP < |P1-P2|, it indicates that the filter cartridge 322 is blocked, the differential pressure alarm system alarms, and the filter cartridge 322 is checked and replaced to ensure that the negative pressure dust collection mechanism 3 can operate normally.

[0028] A backflow prevention structure 351 is provided on the dust collection pipe 35. The backflow prevention structure 351 is installed at the connection between the dust collection pipe 35 and the first filter chamber 321. When the spiral pulse assembly 323 cleans the filter cartridge 322, the first filter chamber 321 is under positive pressure. The backflow prevention structure 351 prevents dust from passing through the dust collection pipe 35 and entering the discharge hopper 23. The backflow prevention structure 351 includes a flow guide 3511, a spring hinge 3512, and a baffle 3513. The baffle 3513 is hinged to both ends of the flow guide 3511 via the spring hinge 3512. When the first filter chamber 321 is under negative pressure (e.g., when the pressure is negative), the backflow prevention structure prevents dust from entering the discharge hopper 23. Figure 4 As shown at point b), when the dust collection fan 34 starts, the baffle 3513 opens relative to the guide shroud 3511 under negative pressure, connecting the integrated pipe 35 to the first filter chamber 321. When the first filter chamber 321 is under positive pressure (as shown at point b), the baffle 3513 opens relative to the guide shroud 3511, connecting the integrated pipe 35 to the first filter chamber 321. Figure 4 As shown at point a), when the spiral pulse assembly 323 is activated, the baffle 3513 closes under the action of the spring hinge 3512, thus separating the integrated pipe 35 from the first filter chamber 321. This prevents the positive air pressure generated by the spiral pulse assembly 323 from passing through the integrated pipe 35, thereby preventing dust from entering the discharge hopper 23. Specifically, an anemometer (not shown in the figure) is also installed on the dust collection pipe 35. The anemometer is used to test the negative pressure wind speed in the dust collection pipe 35. By comparing the wind speed generated by the dust collection fan 34 with the negative pressure wind speed in the dust collection pipe 35, the degree of clogging of the primary filter assembly 32 can be monitored.

[0029] Please combine Figure 1 , Figure 2 and Figure 5 As shown, the waste compression mechanism 4 includes a compression base plate 41, a pushing assembly 44, a gate assembly 45, a compaction chamber 42, a connecting pipe 43, a waste trolley 46, and a safety light curtain 47. The compression base plate 41 is detachably installed on the waste machine frame 1. A connecting plate 412 and casters 411 are provided on the compression base plate 41. The casters 411 are installed at the lower end of the compression base plate 41 to drive the compression base plate 41 to move. The connecting plate 412 is installed on both sides of the compression base plate 41. Bolts pass through the connecting plate 412 and connect it to the waste machine frame 1, thereby installing the waste compression mechanism 4 on the waste machine frame 1 for easy assembly and disassembly of the waste compression mechanism 4. The compaction chamber 42 is fixed on the compression base plate 41. The connecting pipe 43 is installed at the upper end of the compaction chamber 42. 43 is connected to the discharge port 22. The gate assembly 45 is installed at one end of the compaction chamber 42, and the pusher assembly 44 is installed at the other end of the compaction chamber 42. The safety light curtain 47 is installed on one side of the gate assembly 45. The waste trolley 46 is aligned with the gate assembly 45. A through-beam sensor 431 is installed on the connecting pipe 43. When the through-beam sensor 431 senses that the material is full, the pusher assembly 44 drives the waste material in the compaction chamber 42 to move towards the gate assembly 45 to compact the waste material. After compaction is completed, the gate assembly 45 is driven to open, and the pusher assembly 44 pushes the waste material into the waste trolley 46 for storage. The safety light curtain 47 is used to detect whether there are obstacles at the gate assembly 45 to improve safety.

[0030] The gate assembly 45 includes a gate 451, a gate lifting cylinder 452, a gate brush 453, and a mechanical pin 454. The gate lifting cylinder 452 is mounted on the compression base plate 41 and drives the gate 451 to move longitudinally in the compaction chamber 42 to serve as a pressing base plate and to separate the waste cart 46 from the compaction chamber 42. The gate brush 453 is mounted on the upper end of the compaction chamber 42 and aligned with the gate 451 to clean the dust adhering to the gate 451. The mechanical pin 454 is mounted on the compression base plate 41 and aligned with the gate 451. After the gate 451 is lifted, the mechanical pin 454 abuts against the gate 451 to lock the gate 451 and prevent the gate 451 from falling during maintenance, thus avoiding safety hazards.

[0031] The feeding assembly 44 includes an electric cylinder 441, a feeding plate 442, a guide rod structure 443, a horizontal insertion plate structure 444, a guide wheel 445, a feeding brush 446, a brush connecting plate 448, and a lower dust collection box 447. The electric cylinder 441 is mounted on the side wall of the compaction chamber 42. The guide rod structure 443 passes through the side wall of the compaction chamber 42 and is connected to the feeding plate 442 to guide the movement of the feeding plate 442, so that the feeding plate 442 can... For stable directional movement, the electric cylinder 441 drives the pusher plate 442 to move towards the gate 451. The horizontal insert plate structure 444 is installed at the upper end of the pusher plate 442 to cut off and block the waste material from entering the compaction chamber 42 during compaction. The brush connecting plate 448 is installed at the lower end of the pusher plate 442, and the pusher brush 446 is installed at the end of the brush connecting plate 448. The lower dust collection box 447 is installed on the side wall of the compaction chamber 42. The guide wheel 445 is mounted on the brush connecting plate 448 to support the movement of the pusher plate 442. When four conditions are met—the gate 451 descends and closes, the through-beam sensor 431 senses that the compaction chamber 42 is full, the mechanical pin 454 is pulled out, and the safety light curtain 47 does not alarm—the electric cylinder 441 drives the pusher plate 442 to reciprocate toward the gate 451, so that the pusher plate 442 pushes the waste material to press against the gate 451. When the waste material is compressed to the set protection level, the gate lifting cylinder 452 drives the gate 451 to rise, and the pusher plate 442 pushes the compressed waste material onto the waste trolley 46 for the next compression. When the pusher plate 442 moves, it drives the pusher brush 446 to move, so as to sweep the dust accumulated at the bottom of the compaction chamber 42 into the lower dust collection box 447. The lower dust collection box 447 is a pull-out dust collection box for easy dumping of the collected dust.

[0032] The guide rod structure 443 includes a guide rod 4431 and a guide rod fixing plate 4432. The guide rod 4431 passes through the side wall of the compaction chamber 42, with one end fixed to the pusher plate 442 and the other end fixed to the guide rod fixing plate 4432 to ensure that the pusher plate 442 can move stably.

[0033] The horizontal insert plate structure 444 includes a horizontal insert plate 4441, a horizontal insert plate brush 4442, a fixed blade 4443, and a movable blade 4444. The horizontal insert plate 4441 and the movable blade 4444 are fixed to the upper end of the pusher plate 442, and the movable blade 4444 is fixed to the front end of the horizontal insert plate 441. The fixed blade 4443 is fixed to the compaction chamber 42 and close to the connecting pipe 43, aligned with the movable blade 4444. When the electric cylinder 441 drives the pusher plate 442 to move, the movable blade 4444 and the fixed blade 4443 interact to cut... Excess waste is blocked by the horizontal insert plate 4441, which prevents the waste located in the connecting pipe 43 from falling into the compaction chamber 42. The compaction chamber 42 is provided with a horizontal insert plate guide wheel 421, which is rotatably disposed in the compaction chamber 42 and abuts against the two end faces of the horizontal insert plate 4441 to guide and support the movement of the horizontal insert plate 4441. The horizontal insert plate brush 4442 is installed at the upper end of the compaction chamber 42 and aligned with the horizontal insert plate 4441 to clean the dust adhering to the horizontal insert plate 4441.
