Description

Technical Field

[0001] This utility model relates to the field of diatomaceous earth waste recycling technology, specifically a diatomaceous earth carpet waste recycling device. Background Technology

[0002] With the rapid development of environmentally friendly building materials, diatomaceous earth carpets have been widely used in the field of architectural decoration due to their natural environmental protection, moisture regulation, and odor removal properties. However, during the production of diatomaceous earth carpets, the cutting process generates a large amount of irregularly shaped and significantly different-sized tail materials and scraps. Traditional processing methods mainly rely on manual collection, sorting, and transportation, which has the following prominent problems: First, manual recycling is inefficient and labor-intensive. Furthermore, the dusty working environment threatens the respiratory health of workers. Second, due to the diverse forms of the scraps (such as strips, blocks, and fragments), conventional mechanical recycling equipment is difficult to adapt to materials of different sizes and structural strengths, easily leading to equipment overload and shutdown problems.

[0003] In existing technologies, some automated recycling equipment uses crushing rollers and other structures to pulverize materials before recycling. While this can replace some manual operations, it still has significant drawbacks: Firstly, the fixed gap between the crushing rollers cannot adapt to the compaction requirements of materials of varying thicknesses, leading to loose recycled materials or excessive compression that damages the equipment. Secondly, the lack of overload protection mechanisms means that when the instantaneous accumulation of materials is too large, it can easily cause motor stalling, wear and even breakage of transmission components, increasing maintenance costs. Furthermore, while complex grading structures can improve recycling efficiency, they result in bulky equipment, high energy consumption, and difficulty in efficient integration with diatomaceous earth carpet production lines.

A rotary crushing device is housed within the housing. The rotary crushing device includes a drive shaft and a driven shaft rotatably mounted within the housing. A drive crushing wheel, capable of sliding along the drive shaft's axis, is mounted on the drive shaft. The mating section between the drive shaft and the drive crushing wheel is a non-rotating surface. The drive crushing wheel has a conical structure, and its surface is provided with a cutting tool for cutting away excess material. A driven crushing wheel, capable of sliding along the driven shaft's axis, is mounted on the driven shaft. The driven shaft and the driven crushing wheel have a non-rotating cross-section at their mating part. The driven crushing wheel has a conical structure. The small-diameter ends of the driven crushing wheel and the driving crushing wheel are arranged opposite each other. The surface of the driven crushing wheel is provided with a cutting tool for cutting off excess material. A power input part is installed on the driving shaft, and a driving gear is installed on the driving shaft. A driven gear for meshing with the driving gear to transmit torque is installed on the driven shaft. An axial adjustment device is installed on both the driving shaft and the driven shaft. The axial adjustment device adjusts the gap between the driving crushing wheel and the driven crushing wheel in case of overload.

[0005] The axial adjustment device includes a spring seat and a compression spring. The drive shaft is equipped with a spring seat, and a compression spring with its two ends abutting against the spring seat and the drive crushing wheel is provided between the spring seat and the drive crushing wheel. The driven shaft is equipped with a spring seat, and a compression spring with its two ends abutting against the spring seat and the driven crushing wheel is provided between the spring seat and the driven crushing wheel.

Combined with the overload slippage characteristics of the belt drive system, a double overload protection system is formed to effectively avoid the risk of equipment jamming or motor burnout.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] The following is combined with Figures 1 to 3This application introduces a diatomaceous earth carpet waste recycling device, comprising a housing 1, a rotary crushing device inside the housing 1, an inlet 2 at the top of the housing 1, and an outlet 3 at the bottom of the housing 1. The rotary crushing device includes a drive shaft 4 rotatably installed inside the housing 1, with both ends of the drive shaft 4 extending out of the housing 1. One end is equipped with a power input unit for inputting power, and the other end is equipped with a drive gear 10. A drive crushing wheel 5 that can slide along the axis of the drive shaft 4 is installed on the drive shaft 4. The cross-section of the mating part between the drive shaft 4 and the drive crushing wheel 5 is a non-rotating surface. It is worth noting that the non-rotating surface can be an eccentric shaft, an elliptical shaft, or a spline structure with clearance fit. The main purpose is to enable the drive crushing wheel 5 to rotate with the drive shaft 4 and also slide along the axis of the drive shaft 4. The drive shaft 4 is equipped with a spring seat 7. A compression spring 8 is provided between the spring seat 7 and the drive crushing wheel 5, with its two ends respectively abutting against the spring seat 7 and the drive crushing wheel 5. The drive crushing wheel 5 has a conical structure, and a cutting tool 9 for cutting off the waste material is provided on the surface of the drive crushing wheel 5.

[0021] A driven shaft 11 is rotatably mounted inside the housing 1. One end of the driven shaft 11 extends out of the housing 1 and is fitted with a driven gear 12 for meshing with the driving gear 10 to transmit torque. A driven crushing wheel 13, which can slide along the axis of the driven shaft 11, is mounted on the driven shaft 11. The cross-section of the mating part between the driven shaft 11 and the driven crushing wheel 13 is a non-rotating surface. It is worth noting that the non-rotating surface can be an eccentric shaft, an elliptical shaft, or a spline structure with clearance fit. The main purpose is to enable the driven crushing wheel 13 to rotate with the driven shaft 11 and also slide along the axis of the driven shaft 11. The axial adjustment device includes a driven shaft 11 with a spring seat 7 mounted on it. A compression spring 8 is provided between the spring seat 7 and the driven crushing wheel 13, with its two ends respectively abutting against the spring seat 7 and the driven crushing wheel 13. The driven crushing wheel 13 has a conical structure, and the small-diameter ends of the driven crushing wheel 13 and the driving crushing wheel 5 are arranged opposite each other. A cutting tool 9 for cutting off excess material is provided on the surface of the driven crushing wheel 13. (Refer to...) Figure 3 When material enters between the driven crushing wheel 13 and the driving crushing wheel 5, the driven crushing wheel 13 and the driving crushing wheel 5 rotate towards each other under the cooperation of the driving gear 10 and the driven gear 12, thereby crushing the material under the interaction of the cutting tool 9. When there is too much material or the strength is too great between the driven crushing wheel 13 and the driving crushing wheel 5, causing an overload at the input end, the driven crushing wheel 13 and the driving crushing wheel 5 push their respective abutting springs 8 to retract, thereby increasing the gap between the driven crushing wheel 13 and the driving crushing wheel 5, allowing materials that are too large or too strong to fall downwards. This avoids continuous overload, thus forming an overload protection mechanism.

[0022] Specifically, the purpose of the axial adjustment device is to cause the conical surfaces of the driven crushing wheel 13 and the driving crushing wheel 5 to move axially away from each other. The ultimate effect is to achieve overload protection without changing the wheelbase between the driven crushing wheel 13 and the driving crushing wheel 5. Alternatively, a spring seat 7 and a compression spring 8 can be provided on only one of the driven crushing wheel 13 or the driving crushing wheel 5.

[0023] The spring seat 7 is threadedly connected to the drive shaft 4 or the driven shaft 11. The spring seat 7 can rotate threadedly along the axis of the drive shaft 4 or the axis of the driven shaft 11. Adjusting the position of the spring seat 7 on the drive shaft 4 or the driven shaft 11 can adjust the retraction sensitivity under overload. The clearance between the driven crushing wheel 13 and the drive crushing wheel 5 in the initial stage can also be adjusted.

[0024] The feed inlet 2 is a trapezoidal groove structure with a smaller top and a larger bottom, which facilitates the entry of materials into the outer shell 1.

[0025] The opening of the discharge port 3 is located on the side of the outer shell 1. The bottom surface of the outer shell 1 is provided with a guide slope. The bottom of the guide slope is flush with the opening of the discharge port 3 to realize automatic material discharge. In particular, the entire outer shell 1 will vibrate during operation. The vibration and the guide slope work together to discharge the material falling at the bottom of the outer shell 1 out of the discharge port 3.

[0026] A guide baffle 15 is provided below the feed inlet 2. The guide baffle 15 extends obliquely from the inner wall of the outer shell 1 towards the large-diameter end of the active crushing wheel 5 or the driven crushing wheel 13. Without the guide baffle 15, the material entering the feed inlet 2 will spontaneously move towards the small-diameter end of the active crushing wheel 5 or the driven crushing wheel 13 due to gravity on the horizontal plane. This will reduce the crushing efficiency in the middle of the active crushing wheel 5 and the driven crushing wheel 13, and the ends of the active crushing wheel 5 and the driven crushing wheel 13 are prone to overload. The guide baffle 15 can significantly improve the crushing efficiency in the middle of the active crushing wheel 5 and the driven crushing wheel 13.

[0027] The power input unit is pulley 6. The belt drive has the mechanical property of automatically slipping after overload. Compared with chain drive and gear drive, it can automatically form overload protection when overload occurs.

[0028] An arc-shaped transition 14 is provided between the upper part of the guide slope and the inner wall of the outer shell 1, which can reduce the amount of material accumulating inside the outer shell 1 and improve the material flow rate.

[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
