Description

Technical Field

[0001] This utility model relates to the field of glass fiber mat production equipment, and in particular to a glass fiber mat recycling and crushing device. Background Technology

[0002] Fiberglass mat is a high-performance inorganic non-metallic material widely used in construction, electrical insulation, and other fields. In actual production and operation, recycling and reusing fiberglass mat can reduce environmental pollution and resource waste. However, the recycling process first requires crushing the fiberglass mat. During this crushing process, improper operation by workers can result in their clothing or even their arms being caught in the crushing equipment, causing a safety accident. Summary of the Invention

[0003] The purpose of this invention is to provide a glass fiber mat recycling and crushing device that can reduce the risk of safety accidents.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] A glass fiber mat recycling and crushing device includes a housing with a feed inlet at the top. Two connecting seats are fixed to the inner walls on both sides of the housing, and a rotating shaft is fixed to each connecting seat. A swing arm rotatably connected to the rotating shaft is fitted onto the rotating shaft. A guide plate is fixed to the upper surface of the swing arm. An elastic support assembly is provided below the swing arm. The elastic support assembly includes a guide shaft fixed to a guide sleeve and a guide shaft disposed inside the guide sleeve. One end of the guide shaft extends out of the guide sleeve and is rotatably connected to a connecting rod. The connecting rod abuts against the swing arm. A spring is fitted onto the guide sleeve. A first limiting block is fixed to the outer surface of the guide sleeve. A second limiting block is provided on the guide shaft. One end of the spring abuts against the first limiting block and the other end abuts against the second limiting block. A contact switch is provided inside the guide sleeve.

[0006] The lower end of the swing arm is provided with a mounting plate, and a feeding roller is provided between two mounting plates on the same side. Roller shafts are provided at both ends of the feeding rollers. The roller shafts are rotatably connected to the mounting plates. A transmission gear is provided on the roller shafts. A motor is fixed in the housing. The motor has a drive shaft. The end of the drive shaft extends into the housing. A drive gear that meshes with the transmission gear is fixed on the drive shaft.

[0007] A pair of crushing rollers are arranged below the feeding roller. A crushing roller motor that drives the crushing rollers to rotate is fixed on the housing. An inclined discharge plate is arranged below the crushing rollers. The housing is provided with a discharge port that connects with the discharge plate.

[0008] With the above structure, the recycled fiberglass mat is fed from the inlet onto the guide plate, and then conveyed to the space between the crushing rollers by the rotating feed rollers. The crushing rollers crush the fiberglass mat, which then falls onto the outlet plate and is collected and stored from the outlet. If, due to an accident, a worker's arm or other hard object is pulled into the gap between the two guide plates, the hard object pushes the guide plate and the feed roller toward the guide sleeve. The transmission gear of the feed roller disengages from the drive gear, and the feed roller stops rotating and conveying the fiberglass mat. At the same time, one end of the guide shaft extending into the guide sleeve contacts the contact switch, thereby shutting down the entire device. This invention can stop the conveying of materials and stop the machine in time when an accident occurs, reducing the risk of workers being injured by the crushing device and reducing the probability of safety accidents. It is highly safe.

[0009] Preferably, in order to ensure the stability of the connection between the connecting rod and the swing arm, the end of the connecting rod is fixed with a frustum-shaped abutment, which abuts against the swing arm.

[0010] Preferably, in order to facilitate the collection of materials after the glass fiber mat is crushed, a trumpet-shaped collecting pipe is provided between the crushing roller and the discharge plate, and the diameter of the upper end of the collecting pipe is larger than the diameter of the lower end. Attached Figure Description

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 This is a schematic diagram of the assembly of the swing arm and the feed roller of this utility model. Detailed Implementation

[0014] like Figure 1 and Figure 2As shown, the glass fiber mat recycling and crushing device of this utility model includes a box body 1, with a feed inlet 2 at the upper end of the box body. Two connecting seats 3 are fixed to the inner walls on both sides of the box body, and a rotating shaft 4 is fixed on the connecting seats. A swing arm 5, rotatably connected to the rotating shaft, is fitted on the rotating shaft. A guide plate 6 is fixed on the upper surface of the swing arm. An elastic support assembly is provided below the swing arm. The elastic support assembly includes a guide sleeve 7 fixed to it and a guide shaft 8 disposed inside the guide sleeve. One end of the guide shaft extends out of the guide sleeve and is rotatably connected to a connecting rod 9. A frustum-shaped abutment part 91 is fixed to the end of the connecting rod, and the abutment part abuts against the swing arm. A spring 10 is fitted on the guide sleeve. A first limiting block 11 is fixed to the outer surface of the guide sleeve. A second limiting block 12 is provided on the guide shaft. One end of the spring is connected to the guide shaft 91. The first limiting block abuts against the second limiting block at the other end. A contact switch 13 is installed inside the guide sleeve. A mounting plate 14 is installed at the lower end of the swing arm. A feeding roller 15 is installed between the two mounting plates on the same side. Roller shafts 16 are installed at both ends of the feeding roller. The roller shafts are rotatably connected to the mounting plates. A transmission gear 17 is installed on the roller shaft. A motor 18 is fixed in the housing. The motor has a drive shaft 19. The end of the drive shaft extends into the housing. A drive gear 20 that meshes with the transmission gear is fixed on the drive shaft. A pair of crushing rollers 21 are installed below the feeding roller. A crushing roller motor 22 that drives the crushing rollers to rotate is fixed in the housing. An inclined discharge plate 23 is installed below the crushing roller. A trumpet-shaped collecting pipe 24 is installed between the crushing roller and the discharge plate. The diameter of the upper end of the collecting pipe is larger than the diameter of the lower end. The housing is provided with a discharge port 25 that connects with the discharge plate.

[0015] With the above structure, the recycled fiberglass mat is fed from the inlet onto the guide plate, and then conveyed to the space between the crushing rollers by the rotating feed rollers. The crushing rollers crush the fiberglass mat, which then falls onto the outlet plate and is collected and stored from the outlet. If, due to an accident, a worker's arm or other hard object is pulled into the gap between the two guide plates, the hard object pushes the guide plate and the feed roller toward the guide sleeve. The transmission gear of the feed roller disengages from the drive gear, and the feed roller stops rotating and conveying the fiberglass mat. At the same time, one end of the guide shaft extending into the guide sleeve contacts the contact switch, thereby shutting down the entire device. This invention can stop the conveying of materials and stop the machine in time when an accident occurs, reducing the risk of workers being injured by the crushing device and reducing the probability of safety accidents. It is highly safe.
