Description

Technical Field

[0001] The utility model relates to the technical field of umbrella processing, in particular to a waste collection device for wooden middle sticks of umbrellas. Background Art

[0002] A waste collection device is a device that can centrally collect waste materials such as scraps or debris generated during the processing and production process. The scraps or debris are introduced into the collection device for storage through a collection pipe connected to the processing device. Some collection devices are also equipped with a crushing component that can crush the collected scraps and debris into waste particles of uniform size, making subsequent processing and recycling more convenient.

[0003] During the processing of the wooden center rod of an umbrella, wood scraps and sawdust will be produced. In order not to affect the environment and facilitate cleaning, a waste collection device will be used to collect the wood waste generated by the processing and break it into particles of uniform size. The collected waste can be compacted to produce synthetic wood boards, etc., which effectively reduces the difficulty of waste collection and makes cleaning after processing more convenient. At the same time, it can better recycle waste and reduce the processing and production costs of wooden center rods in disguise.

[0004] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing waste recovery device recycles the wood chips generated by the processing of the middle rod, it draws them into the waste recovery device through a high-negative pressure fan, and separates the wood chips from the airflow through a built-in filter plate. However, after using it for a period of time, it is necessary to stop the machine to empty the wood chips accumulated on the filter plate, otherwise it is easy to cause the filter plate to be blocked and the negative pressure is insufficient to fully draw in the wood chips, which not only affects the waste collection efficiency, but also increases the workload of the operator, making it more cumbersome to use.

[0022] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0023] See also Figure 1-4As shown, the technical solution adopted in this specific embodiment is: a device for collecting waste wood sticks of umbrellas, comprising a collecting main body 1 and a suction pipe 2 arranged on one side of the collecting main body 1 and connected to the collecting main body 1, the collecting main body 1 comprises an isolation outer wall 11 and an air flow channel 12 penetrating the side wall of the isolation outer wall 11 and connected to the suction pipe 2, the isolation outer wall 11 is also provided with a plurality of negative pressure fans 13 with one end penetrating the air flow channel 12 and extending into the air flow channel 12, two of which are provided in this embodiment, the inner wall of the air flow channel 12 is provided with a filter plate structure 14, the filter plate structure 14 comprises a fixed block 21 fixed to the inner wall of the air flow channel 12 and an inverted V-shaped filter plate 25 arranged on the inner side of the fixed block 21, the wood chips are separated when passing through the filter plate 25, attached to the filter plate 25, and the wood chips are caused to flow along the inverted V-shaped filter plate 2 by air pressure. 5 gradually moves downward, so that the surface of the filter plate 25 will not be completely clogged by the wood chips. When in use, the suction pipe 2 is placed on the processing table of the wooden umbrella middle rod processing equipment, and the distance between the end of the suction pipe 2 and the processing table is minimized, and the negative pressure fan 13 is started at the same time, so that the negative pressure fan 13 draws in the airflow to generate negative pressure, and then the wood chips are drawn into the airflow channel 12 through the suction pipe 2, and as the airflow continues to move, the wood chips are separated when passing through the filter plate 25 and attached to the filter plate 25, and the continuously flowing gas will generate downward pressure along the surface of the filter plate 25, and then the wood chips attached to the convex part of the filter plate 25 are pushed downward, thereby keeping the convex part of the filter plate 25 unobstructed, ensuring the negative pressure strength, and thus avoiding the negative pressure from affecting the wood chip waste collection efficiency. At the same time, there is no need to frequently disassemble and clean, and it is relatively simple and convenient to use;

[0024] The filter plate structure 14 also includes a supporting filter plate 24 disposed between the filter plate 25 and the fixing block 21, which is beneficial for ensuring the filtering effect while allowing the pushed-down wood chips to fall on the supporting filter plate 24 for collection;

[0025] The top surface of the supporting filter plate 24 is provided with an arc-shaped groove, which is beneficial to increase the amount of waste collected;

[0026] A guide block 15 is provided at the bottom of the airflow channel 12 away from the exhaust end, which is helpful to guide the gas so that it can be better discharged from the airflow channel 12;

[0027] The other side of the collecting host 1 is also provided with an exhaust pipe 3 which is connected to the air flow channel 12, which is conducive to the air flow being discharged from the collecting host 1;

[0028] The collecting host 1 is also provided with an inspection door 4, which is conducive to making it more convenient to disassemble and assemble the filter plate 25;

[0029] The inner wall of the fixing block 21 is provided with a sliding groove 22, and the end of the supporting filter plate 24 is slidably connected with the inner wall of the sliding groove 22. A return spring 23 is provided between the bottom of the inner wall of the sliding groove 22 and the bottom surface of the end of the supporting filter plate 24. When the airflow blows on the supporting filter plate 24, the supporting filter plate 24 is pressed down and the return spring 23 is squeezed to generate elastic force. When the airflow pressure decreases, the supporting filter plate 24 and the filter plate 25 are pushed up by the elastic force of the return spring 23, thereby causing the filter plate 25 to swing up and down, thereby better loosening the attached wood chips and making them slide down in accordance with the air pressure.

[0030] The bottom surface of the filter plate 25 is also provided with a swing hammer 26, and the swing hammer 26 includes a wind receiving handle 33 with one end movably engaged with the bottom surface of the filter plate 25 and a reset spring piece 32 arranged between the bottom surface of the wind receiving handle 33 and the bottom surface of the filter plate 25. The other end of the wind receiving handle 33 is provided with a hollow impact ball 34, and the inner wall of the hollow impact ball 34 is provided with a plurality of freely rolling balls 35. In this embodiment, when the airflow flows downward, downward wind pressure is generated to cause the wind receiving handle 33 to twist downward and squeeze the reset spring piece 32, and when the air pressure is reduced or disappears, the wind receiving handle 33 is pushed back by the reset spring piece 32, thereby causing the wind receiving handle 33 to reverse and collide with the impact ball 34, and at the same time, the rolling ball 35 rolls and hits the inner wall of the impact ball 34 to cause shaking, thereby loosening the wood chips attached to the filter plate 25 and making it easier to fall off;

[0031] The top surface of the wind receiving handle 33 is provided with a plurality of fin-shaped wind blades. In the present embodiment, three fin-shaped wind blades are provided, which are beneficial to enhancing the separation downward force, making the wind receiving handle 33 twist at a larger angle and the anti-hammer impact force stronger.

[0032] Working principle of the utility model: when the utility model is used, the suction pipe 2 is placed on the processing table of the wooden umbrella middle rod processing equipment, and the distance between the end of the suction pipe 2 and the processing table is minimized, and the negative pressure fan 13 is started at the same time, so that the negative pressure fan 13 draws in the airflow to generate negative pressure, and then the wood chips are drawn into the airflow channel 12 through the suction pipe 2, and as the airflow continues to move, the wood chips are separated when passing through the filter plate 25 and attached to the filter plate 25, and the continuously flowing gas will generate downward pressure along the surface of the filter plate 25, and then the wood chips attached to the raised part of the filter plate 25 are pushed downward, thereby keeping the convex part of the filter plate 25 unobstructed, ensuring the negative pressure strength, and avoiding the influence of insufficient negative pressure on the wood chip waste collection efficiency, and at the same time, there is no need for frequent disassembly and cleaning, and it is relatively simple and convenient to use.
