Description

Technical Field

[0001] This utility model relates to the field of shredding devices, and in particular to a shredding device for paper product production. Background Technology

[0002] This invention relates to a paper product shredding device, primarily addressing existing cutting technologies and equipment used in paper product processing. With the widespread application of paper products in daily life and industrial production, higher demands are placed on the processing precision, efficiency, and quality of paper products. Traditional paper product cutting relies heavily on mechanical blades or simple physical cutting methods, which are often ill-suited to the diverse and high-precision cutting needs of modern paper products. For example, traditional cutting technologies struggle to meet the production requirements of certain complex-shaped paper products or those requiring fine processing. In the paper product manufacturing process, cutting precision directly impacts product quality and subsequent processes. However, due to technological limitations, traditional cutting devices often fail to achieve high-precision cutting, resulting in low product qualification rates. Simultaneously, low cutting efficiency also restricts the production speed of paper products and hinders the improvement of enterprise capacity. This paper product shredding device addresses the shortcomings of existing paper product cutting technologies and equipment by introducing new technologies, processes, and materials to develop a high-precision, high-efficiency, easy-to-operate, and environmentally friendly paper product shredding device to meet the needs of modern paper product production.

[0003] Crushing is an important process in paper product manufacturing, used to break down waste paper products or paper scraps for recycling. Traditional paper product crushing equipment often suffers from inconvenient maintenance. Once the equipment malfunctions, it requires complex disassembly for repair, which seriously affects the stability of the equipment. Therefore, we propose a paper product crushing device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a shredding device for paper product manufacturing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A paper product shredding device includes: a housing, a hopper fixedly installed at the top of the housing, a fixed shell slidably installed inside the housing, a plurality of rotating rods rotatably installed inside the fixed shell, a plurality of cutting blades fixedly installed on the rotating rods, a gear fixedly installed on one side of the rotating rod, two adjacent gears meshing with each other, a motor fixedly installed on one side of the fixed shell, the output end of the motor fixedly connected to one of the rotating rods, a rotating block rotatably installed on one side of the fixed shell, two connecting rods rotatably installed on one side of the rotating block, a connecting rod rotatably installed on one side of the two connecting rods, a limiting groove matching the connecting rod 2 being provided on the housing, a sliding plate fixedly installed on one side of the connecting rod 2, a spring fixedly installed on one side of the sliding plate, and the spring fixedly installed inside the fixed shell.

[0007] Preferably, two drive wheels are rotatably installed inside the fixed shell, and the two drive wheels are connected to the same drive belt on their outer sides. A crushing blade is fixedly installed at the top of each of the two drive wheels. A second motor is fixedly installed inside the fixed shell, and the output end of the second motor is fixedly connected to one of the drive wheels. T-shaped sliders are fixedly installed on both sides of the fixed shell, and the T-shaped sliders are slidably installed inside the shell.

[0008] Preferably, two water spray pipes are fixedly installed inside the outer shell, and water storage tanks are fixedly installed on both sides of the outer shell. A water pump is fixedly installed on one side of the water storage tank, and a connecting pipe is fixedly installed at the output end of the water pump. The connecting pipe is fixedly connected to the water spray pipes.

[0009] Preferably, a support block is fixedly installed at the bottom of the outer shell, a collection box is slidably installed inside the support block, a filter screen is fixedly installed inside the collection box, a handle and a drain pump are fixedly installed on one side of the collection box, and a connection groove matching the drain pump is provided on the collection box.

[0010] Preferably, the fixed housing has a movable groove that matches the two connecting rods, the fixed housing has a sliding groove that matches the two connecting rods, the fixed housing has a square sliding groove that matches the sliding plate, and the spring is fixedly installed in the square sliding groove.

[0011] Preferably, the fixed housing has an installation groove that matches the second motor, a rotation groove that matches the two transmission wheels, and a transmission groove that matches the transmission belt.

[0012] In this utility model, a paper product shredding device is described. The paper product to be shredded is fed into a hopper and enters the device. A first motor is started, driving a rotating rod and cutting blades to rotate. The rotating rod rotates within a fixed housing and has multiple cutting blades fixed on it for shredding the paper product. A gear is fixedly installed on one side of the rotating rod. Adjacent rotating rods mesh with each other through the gears to achieve synchronous reverse rotation. The first motor provides power to one of the rotating rods, which in turn drives the other rotating rods and cutting blades to rotate. Simultaneously, a second motor drives a transmission wheel to rotate, which in turn drives a transmission belt. The transmission belt drives two transmission wheels and the shredding blades to rotate, further shredding the paper product. Water mist is sprayed from a water spray pipe to reduce heat and dust generated during the shredding process and to prevent static electricity.

[0013] In this utility model, a paper product shredding device is provided with water and power to the spray pipe through a water storage tank and a water pump. The shredded paper falls into the collection box, collecting the shredded paper products and water. At the same time, a filter screen is fixedly installed in the collection box to filter out the water, retaining only the paper product fragments. Excess water is discharged through a drain pump, so that the paper products can enter the next process. When the device needs to be maintained, the rotating block is rotated, which moves the first connecting rod and allows the second connecting rod to slide inside the fixed shell. These components form a linkage mechanism to adjust the position of the fixed shell inside the outer shell, making it easy to pull out the entire device for maintenance of the internal structure. The sliding plate and spring provide the restoring force of the linkage mechanism to ensure that the fixed shell can slide stably inside the outer shell.

[0014] This utility model has a reasonable structural design. Through the cooperation of multiple structures, it can meet the shredding needs in the paper product production process. The quick disassembly and assembly structure greatly simplifies the maintenance process and improves the maintainability and production efficiency of the equipment. Attached Figure Description
