Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a rolling household waste bag breaking device. Background Technology

[0002] With increasing environmental awareness, waste sorting and disposal efforts are being strengthened. After sorting, some waste can be reused, turning waste into treasure. Currently, most residents in China use plastic bags to pack their waste. To achieve further automated waste sorting and improve waste disposal efficiency, it is necessary to break open the plastic bags to disperse the waste inside for further sorting.

[0003] Existing technologies mainly rely on manual separation of plastic bags. However, this method suffers from poor working conditions, low efficiency, and cannot meet the requirements for automatic bag breaking. Existing garbage bag breaking devices have fixed blades inside the drum. During the bag breaking process, the fixed blades are rotated only by the rotation of the drum. Garbage inside the drum is prone to sticking and getting stuck on the blades, resulting in low bag breaking efficiency and affecting the bag breaking effect. Therefore, we propose a rolling household waste bag breaking device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rolling household waste bag breaking device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rolling household waste bag-breaking device, comprising a base plate, with multiple support seats fixedly connected to both sides of the top of the base plate, and I-beam support wheels rotatably mounted on the top of each support seat. Two I-beam support wheels on the same side are fixedly sleeved on both sides of a rotating shaft. The rotating shaft is rotatably connected to the support seats, and one rotating shaft is driven by a reduction motor. The reduction motor is fixedly connected to the top of the base plate. The multiple I-beam support wheels abut against two support rings, and the two support rings are fixedly sleeved on both sides of a roller. Multiple bag-breaking nails are fixedly connected to the inner wall of the roller. Support frames are fixedly connected to the inner walls of the openings at both ends of the roller. A drive shaft is slidably engaged within the support frame. Multiple cutting blades are fixedly connected to the outer wall of the drive shaft. Both ends of the drive shaft abut against end face cams. The opposite ends of the end face cams are fixedly connected to both ends of an upper bracket. The upper bracket is fixedly mounted on the top of the roller, and one end of a support plate is fixedly connected to both sides of the middle of the upper bracket. The other end of the support plate is fixedly connected to both sides of the top of the base plate.

[0006] Preferably, the support plate has an L-shaped structure.

[0007] Preferably, the upper support has a U-shaped structure.

[0008] Preferably, the cutting blade and the bag-breaking nail are evenly distributed around the circumference, and the cutting blade and the bag-breaking nail are staggered.

[0009] Preferably, the drive shaft has recessed grooves on both sides, and sliders are slidably engaged on both sides of the grooves, with the sliders being fixedly connected to the support frame.

[0010] Preferably, bearing seats are fixedly connected to both ends of the transmission shaft, and rollers are rotatably connected to each bearing seat, with the rollers abutting against the end face cams.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The bagged garbage inside the drum is broken by a rotating drum and a bag-breaking nail fixed to the inner wall of the drum.

[0013] 2. When the drum rotates circumferentially, it works with the fixed support frame to drive the locked drive shaft to rotate synchronously. The drive shaft slides against the end face cam, and in turn, the fixed end face cam makes the drive shaft rotate circumferentially while simultaneously moving in a reciprocating linear motion. The drive shaft then drives the fixed cutting blade to move laterally in an alternating manner while following the rotation of the drum, thereby cutting and breaking the bagged waste and improving the bag-breaking effect.

[0014] 3. The reciprocating linear moving cutting blades cut and pull the bagged garbage inside the drum, preventing the garbage from sticking to or getting stuck on the bag-breaking nails. Attached Figure Description

The device is characterized in that: multiple support seats 3 are fixedly connected to both sides of the top of the base plate 1; I-beam support wheels 4 are rotatably mounted on the top of each support seat 3; two I-beam support wheels 4 on the same side are fixedly sleeved on both sides of a rotating shaft 5; the rotating shaft 5 is rotatably connected to the support seats 3, and one rotating shaft 5 is drively connected to a reduction motor 2; the reduction motor 2 is fixedly connected to the top of the base plate 1; the multiple I-beam support wheels 4 abut against two support rings 7; and the two support rings 7 are fixedly sleeved on rollers 6. On both sides, multiple bag-breaking nails 11 are fixedly connected to the inner wall of the roller 6. Support frames 8 are fixedly connected to the inner wall of the openings at both ends of the roller 6. Drive shafts 9 are slidably engaged inside the support frames 8. Multiple cutting blades 10 are fixedly connected to the outer wall of the drive shafts 9. The two ends of the drive shafts 9 abut against the end face cams 13. The opposite ends of the end face cams 13 are fixedly connected to the two ends of the upper bracket 12. The upper bracket 12 is fixedly installed on the top of the roller 6, and one end of the support plate 14 is fixedly connected to both sides of the middle part of the upper bracket 12. The other end of the support plate 14 is fixedly connected to the top two sides of the bottom plate 1. Example

[0024] Reference Figure 1-6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the support plate 14 has an L-shaped structure, and the support plate 14 supports and fixes the upper bracket 12.

[0025] Specifically, the upper bracket 12 has a U-shaped structure, and the upper bracket 12 supports and fixes the two end face cams 13.

[0026] Specifically, the cutting blades 10 and the bag-breaking nails 11 are evenly distributed around the circumference, and the cutting blades 10 and the bag-breaking nails 11 are staggered. The cutting blades 10 and the bag-breaking nails 11 work together to realize the bag-breaking operation of bagged garbage inside the drum 6.

[0027] Specifically, the drive shaft 9 has recessed grooves 91 on both sides, and sliders are slidably engaged on both sides of the grooves 91. The sliders are fixedly connected to the support frame 8. The sliding engagement of the grooves 91 and the sliders enables the drive shaft 9 to rotate in a circular motion while reciprocating in a linear motion.

[0028] Specifically, bearing seats 92 are fixedly connected to both ends of the transmission shaft 9, and rollers 93 are rotatably connected to the bearing seats 92. The rollers 93 abut against the end face cam 13, and the rollers 93 are in rolling connection with the end face cam 13.

[0029] The working principle and process are as follows: The roller 6 is tilted to facilitate the discharge of bagged waste. Waste requiring bag breaking is placed into the roller 6. The reduction motor 2 is energized and operates. The output shaft of the reduction motor 2 is fixedly connected to a pulley, and the rotating shaft 5 is also fixedly connected to a pulley. The reduction motor 2 and the rotating shaft 5 are connected by a transmission belt through the fixed pulleys. When the reduction motor 2 is energized, it drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the fixed I-beam support wheel 4 to rotate. The I-beam support wheel 4 is fixedly fitted with a rubber ring, which abuts against the support ring 7. The outer wall of the support ring 7 has anti-slip textures to increase friction at the contact point. The support ring 7 rotates under the drive of the I-beam support wheel 4, which in turn drives the fixed roller 6 to rotate circumferentially. The roller 6 then rotates... The bag-breaking nails 11 fixed to the inner wall rotate circumferentially, breaking the bags of the input waste. Simultaneously, the roller 6 drives the fixed Y-shaped support frame 8 to rotate circumferentially. The support frame 8 drives the snap-fit ​​transmission shaft 9 to rotate, which in turn drives the fixed-mount cutting blade 10 to rotate circumferentially. Simultaneously, the transmission shaft 9 drives the roller 93 to rotate circumferentially. The roller 93 abuts against the end face cam 13. The two end face cams 13 are positioned opposite each other, with their protruding ends staggered. That is, when the protruding end of one end face cam 13 drives the rotating transmission shaft 9 to move to the left, the other end face cam 13 is in a recessed position. After one end face cam 13 moves to the recessed position, the rotating transmission shaft 9 moves to the right. Thus, the rotation of the transmission shaft 9 simultaneously achieves… Figure 6 As shown, the left and right linear movement, the drive shaft 9, and the cutting blade 10 follow the circumference of the drum 6 to achieve reciprocating linear movement. The cutting blade 10 cuts and pulls the bagged garbage inside the drum 6, improving the bag breaking effect and preventing garbage from sticking to or remaining on the bag breaking nails.
