Description

Technical Field

[0001] This utility model relates to the technical field of PC film production equipment, specifically to a PC film edge material crushing device. Background Technology

[0002] After the PC film is formed, the edge material on both sides needs to be cut off by a cutting mechanism. Currently, most of the edge material is wound up by a winding device and then crushed for reuse. This requires workers to remove the wound edge material regularly, replace the roll, and wind the edge material back onto the roll, increasing the workload and wasting manpower. The existing crusher crushes the PC material by rotating the crushing roller at high speed, but the particle size of the crushed material is inconsistent, which easily produces fine powder, affecting secondary mixing and reuse. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a PC film edge crushing device.

[0004] This utility model includes a crushing box, inside which a transverse extrusion feeding roller, a longitudinal extrusion feeding roller, and a crushing roller are arranged sequentially from top to bottom. The transverse extrusion feeding roller has a set of annular indentation blades on its roller surface, and the longitudinal extrusion feeding roller has a set of transverse indentation blades arranged in annular array on its roller surface. The crushing roller has multiple sets of crushing rods on its roller surface. The top of the crushing box has an openable cover with a feed guide groove on the cover. The bottom of the crushing box has a receiving chute. The crushing box is equipped with a crushing motor that drives the transverse extrusion feeding roller, the longitudinal extrusion feeding roller, and the crushing roller to rotate.

[0005] The transverse extrusion feed roller consists of a first fixed roller and a first movable roller, and the longitudinal extrusion feed roller consists of a second fixed roller and a second movable roller. A set of annular indentation blades is located on the first movable roller, and a set of transverse indentation blades is located on the second movable roller. The first fixed roller and the first movable roller, the second fixed roller and the second movable roller, and the first fixed roller and the second fixed roller are all connected by gear transmission. The second fixed roller and the crushing roller are connected by gearbox transmission.

[0006] The crushing box is provided with a first movable roller mounting groove and a second movable roller mounting groove, and a sliding block is provided in both the first movable roller mounting groove and the second movable roller mounting groove. The first movable roller and the second movable roller are respectively mounted on the corresponding sliding block, and a sliding block tensioning spring is provided in both the first movable roller mounting groove and the second movable roller mounting groove.

[0007] The first movable roller mounting groove and the second movable roller mounting groove are arranged in parallel and are both inclined.

[0008] The feed guide chute is an arc-shaped structure with its opening tilted to one side.

[0009] The advantages of this invention are: after the edge material enters the crushing box, it is first pressed by the transverse extrusion feeding roller to create multiple vertical indentations, and then it enters the longitudinal extrusion feeding roller to create multiple transverse indentations, forming crisscrossing indentations. When it passes through the crushing roller, the crushing rod can easily break up the edge material from each indentation, resulting in uniform particle size of the crushed material.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] As shown in the attached figure, the present invention includes a crushing box 40. Inside the crushing box 40, from top to bottom, there are a transverse extrusion feeding roller 41, a longitudinal extrusion feeding roller 42, and a crushing roller 43. The transverse extrusion feeding roller 41 has a set of annular indentation blades 45 on its roller surface. The longitudinal extrusion feeding roller 42 has a set of transverse indentation blades 46 arranged in annular array on its roller surface. The crushing roller 43 has multiple sets of crushing rods 47 on its roller surface. The top of the crushing box 40 is provided with an openable cover 48, and a feed guide groove 49 is provided on the cover 48. The bottom of the crushing box 40 is provided with a receiving chute 50. The crushing box 40 is provided with a crushing motor 51 that drives the transverse extrusion feeding roller 41, the longitudinal extrusion feeding roller 42, and the crushing roller 43 to rotate.

[0017] The cut edge material enters the crushing box 40 through the feed guide 49. First, it is squeezed by the transverse extrusion feed roller 41 to create multiple longitudinal indentations. Then, when it passes through the longitudinal extrusion feed roller 42, it is squeezed to create multiple transverse indentations. The crisscrossing indentations divide the edge material into multiple small squares. At the same time, the small squares are connected to each other without being cut off. When it passes through the crushing roller 43, the crushing rod 47 strikes it, causing the small squares to separate and form independent fragments. The edge material can greatly reduce the generation of powder during crushing, and the crushed particle size is uniform. After crushing, it is collected and discharged through the receiving chute 50.

[0018] In this case, both the annular indentation blade 45 and the transverse indentation blade 46 are blunt blades without sharpening. Furthermore, the indentation depth of the transverse extrusion feed roller 41 and the longitudinal extrusion feed roller 42 is the same. When the edge material passes through the annular indentation blade 45 and the transverse indentation blade 46, it is only indented, avoiding direct cutting of the edge material. Preferably, the transverse extrusion feed roller 41 is composed of a first fixed roller and a first movable roller, the longitudinal extrusion feed roller 42 is composed of a second fixed roller and a second movable roller, a set of annular indentation blades 45 is located on the first movable roller, a set of transverse indentation blades 46 is located on the second movable roller, the first fixed roller and the first movable roller, the second fixed roller and the second movable roller are all connected by gear transmission, and the second fixed roller and the crushing roller 43 are connected by gear transmission.

[0019] The first and second fixed rollers are fixed in place and rotate, while the first and second movable rollers can adjust their positions. The crushing motor 51 drives the second fixed roller through the transmission shaft. When the second fixed roller rotates, it simultaneously drives the first fixed roller and the crushing roller 43 to rotate. The gearbox is used to increase the speed of the crushing roller 43. The edge material with indentation is scattered and falls off by the crushing rod 47 on the crushing roller 43.

[0020] Furthermore, the crushing box 40 is provided with a first movable roller mounting groove and a second movable roller mounting groove, and a sliding block 53 is provided in both the first movable roller mounting groove and the second movable roller mounting groove. The first movable roller and the second movable roller are respectively mounted on the corresponding sliding block 53. A sliding block tensioning spring 54 is provided in both the first movable roller mounting groove and the second movable roller mounting groove.

[0021] The sliding block tensioning spring 54 is used to press the sliding block 53 towards the first fixed roller or the second fixed roller, so that the first movable roller and the second movable roller can fit tightly against the corresponding first fixed roller and the second fixed roller. At the same time, the first movable roller and the second movable roller have a certain clearance space to facilitate the passage of edge material. The sliding block tensioning spring 54 is an adjustable tensioning spring used to adjust the squeezing force between the movable roller and the fixed roller.

[0022] Furthermore, the first movable roller mounting groove and the second movable roller mounting groove are arranged in parallel and are both inclined.

[0023] The first movable roller mounting groove and the second movable roller mounting groove are inclined at a lower angle to the side closer to the fixed roller, and the first movable roller mounting groove and the second movable roller can adhere to the fixed roller by their own weight.

[0024] Furthermore, the feed guide 49 has an arc-shaped structure with its opening tilted to one side. This prevents foreign objects from falling into the crushing box 40 from the feed guide 49.
