Description

Technical Field

[0001] The utility model relates to the field of foam cutting equipment, in particular to a waste collection mechanism of foam cutting equipment. Background Art

[0002] After processing, plastic foam boards are typically cut into smaller pieces for easier use. Large cutting lines are used for horizontal, vertical, and vertical cutting, each of which produces two thin layers of waste. Furthermore, the plastic foam boards to be cut are relatively large, typically 6 meters long, 1 meter high, and 1.2 meters wide, so the cutting lines are also long, sometimes tens of meters long.

[0003] The large amount of waste generated by existing cutting is characterized by large area, light weight and long distance. The foam particles on the edge of the waste are very easy to fall off and fly, making collection very difficult. The existing foam cutting equipment lacks a waste collection structure. If the waste is not crushed immediately, it will occupy a large amount of storage space and the transportation cost will be high.

[0004] Therefore, in view of the fact that the above-mentioned existing foam cutting equipment lacks a waste recycling structure and is inconvenient in use, a waste collection mechanism of the foam cutting equipment can be designed to solve the above-mentioned problem. Utility Model Content

[0007] The preferred method is to use a two-stage crushing mechanism with multiple blades, a dual-shaft front end, and a single-shaft rear end to ensure both the maximum crushing volume and the degree of crushing. The blades are four-edged. Due to the large number of blades, to prevent excessive torque from simultaneous cutting, all moving blades are evenly distributed radially along the main shaft, using the blades as the reference. This ensures a uniform load distribution along the main shaft, avoids instantaneous excessive loads that could damage the mechanism, and increases its service life. A suction device is also connected to the rear end of the crusher to recycle and package the crushed foam.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting up two crushing operations, a multi-blade structure, a dual-shaft front end, and a single-shaft rear end structure, the amount and degree of crushing can be ensured. The blades adopt a four-edge structure. Due to the large number of blades, in order to prevent the instantaneous torque from being too large when multiple blades are cutting at the same time, all the moving blades are evenly distributed in the radial direction of the main shaft with the blade as the reference, to ensure that the load is evenly distributed in the radial direction of the main shaft, to avoid the instantaneous excessive load and damage to the mechanism, and to increase the service life of the mechanism. At the same time, a suction device is connected to the rear end of the crusher to recycle and package the crushed foam. The waste generated by cutting can be collected and crushed on the line at one time and then recycled and stored, which greatly reduces the storage space and reduces the transportation cost. At the same time, it also avoids the problem of foam particles flying due to secondary recycling. It overcomes the lack of a waste recovery structure in existing foam cutting equipment. The large amount of waste generated during cutting has the characteristics of large area, light weight, and long distance. The foam particles on the edge of the waste are very easy to fall off and fly, making collection very difficult. If the waste is not crushed immediately, it will occupy a large amount of storage space and the transportation cost is also high.

[0016] 2. By setting up two crushing operations and adopting a multi-blade structure, a double-shaft front end, and a single-shaft rear end structure, the amount and degree of crushing are ensured. At the same time, the blade adopts a four-edge structure. Due to the large number of blades, in order to prevent the instantaneous torque from being too large when multiple blades are cutting at the same time, all the moving blades are evenly distributed in the radial direction of the main shaft based on the blades, ensuring that the load is evenly distributed in the radial direction of the main shaft, avoiding the situation where the instantaneous load is too large and the mechanism is damaged, thereby increasing the service life of the mechanism. At the same time, the rear end of the crusher is connected to a suction device to recycle and package the crushed foam. The crusher is installed under the line together with the conveyor belt to complete the collection, crushing, and recycling of waste materials. The waste generated by cutting can be collected and crushed on the line at one time and then recycled and stored, which greatly reduces the storage space and reduces the transportation cost. At the same time, it also avoids the problem of foam particles flying due to secondary recycling, completing the waste disposal of the foam cutting equipment; BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-Figure 3The utility model provides an embodiment of a waste collection mechanism for a foam cutting device, comprising a movable blade 1, a main shaft 2, a powder upper shaft 3, a powder lower shaft 4, a powder front fixed blade 5, a powder rear fixed blade 6, two powder main shafts 7, two powder fixed blades 8, an air suction device 9, a crusher 10, and a conveyor belt 11. The movable blade 1 is configured as an annular blade; the movable blade 1 is provided with the main shaft 2; multiple movable blades 1 are provided on the main shaft 2; the movable blades 1 and the main shaft 2 are provided as a group, and two groups are provided in total; a powder front fixed blade 5 is provided at the lower end of the movable blade 1; a powder rear fixed blade 6 is provided at the rear end of the powder front fixed blade 5; a powder upper shaft 3 is provided on the main shaft 2; a powder lower shaft 4 is provided at the lower end of the powder upper shaft 3; the powder upper shaft 3 and the powder lower shaft 4 are provided in parallel in the vertical direction; and the powder upper shaft 3 and the powder lower shaft 4 have the same structure. A second powder spindle 7 is mounted on one side of the first powder upper shaft 3. Two powder fixed blades 8 are mounted on the second powder spindle 7. These two spindles 7 and two powder fixed blades 8 share the same structure as the movable blade 1 and spindle 2, and are located on one side of the movable blade 1 and spindle 2. The two spindles 7 and two powder fixed blades 8 are arranged as a single set, while the movable blade 1 and spindle 2 are arranged as two sets. An air suction device 9 is mounted on one side of the second powder spindle 7. A crusher 10 is mounted on the outside of the spindle 2. A conveyor belt 11 is mounted on one side of the crusher 10. The conveyor belt 11 is in the shape of a long rectangle. The crusher 10, along with the waste conveyor belt 11, is mounted below the line. The crusher 10 performs two crushing operations and utilizes a multi-blade structure, with two shafts at the front and a single shaft at the rear. The blades are four-edged. The blades of all movable blades 1 are evenly distributed radially along the spindle 2, based on the blade edge. The crushing is done twice, with a multi-blade structure, a dual-shaft front end, and a single-shaft rear end to ensure the amount and degree of crushing. The blades are of a four-edged structure. Due to the large number of blades, in order to prevent the instantaneous torque from being too large when multiple blades are cutting simultaneously, all the moving blades 1 are evenly distributed radially along the main shaft 2, with the blades as the reference. This ensures that the load is evenly distributed radially along the main shaft 2, avoids excessive instantaneous loads that damage the mechanism, and increases the service life of the mechanism. At the same time, the rear end of the crusher 10 is connected to a suction device 9 to recycle and package the crushed foam. The crusher 10 is installed below the line together with the conveyor belt 11 to complete the collection, crushing, and recycling of waste materials.

[0023] During operation, in view of the large quantity and size of the foam waste boards, a two-step crushing, multi-blade structure, a double-shaft front end, and a single-shaft rear end structure are adopted to ensure the crushing amount and degree. The blade adopts a four-edge structure. Due to the large number of blades, in order to prevent the instantaneous torque from being too large when multiple blades are cutting simultaneously, all the moving blades 1 are evenly distributed radially along the main shaft 2 based on the blades to ensure that the load is evenly distributed radially along the main shaft 2, avoiding the situation where the instantaneous load is too large and damages the mechanism, thereby increasing the service life of the mechanism. At the same time, the rear end of the crusher 10 is connected to the suction device 9 to recycle and package the crushed foam. The crusher 10 is installed under the line together with the conveyor belt 11 to complete the collection, crushing, and recycling of the waste materials, thus completing all the work.

[0024] Through the above steps, a double crushing process, a multi-blade structure, a dual-shaft front end, and a single-shaft rear end are implemented to ensure both the amount and degree of crushing. The blades utilize a four-edged structure. Due to the large number of blades, to prevent excessive torque from simultaneous cutting, all blades of the movable cutter 1 are evenly distributed radially along the main shaft 2, with the blades serving as the reference. This ensures a uniform load distribution along the main shaft 2, preventing damage from excessive transient loads and increasing the service life of the mechanism. Furthermore, a suction device 9 is connected to the rear end of the crusher 10 to recycle and package the crushed foam. Cutting waste can be collected and crushed immediately on the line before being recycled and stored, significantly reducing storage space and transport costs. This also avoids the problem of foam particles flying due to secondary recycling. This overcomes the drawbacks of existing foam cutting equipment, which lacks a waste recovery mechanism. The large amount of waste generated during cutting is large, lightweight, and requires long distances to be collected. Furthermore, foam particles at the edges of the waste easily fall off and fly, making collection difficult. Furthermore, if the waste is not immediately crushed, it takes up significant storage space and incurs high transport costs. This approach effectively completes waste disposal for foam cutting equipment.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
