Description

Technical Field

[0001] This utility model relates to the field of nonwoven bag production technology, and in particular to an automatic waste removal device for nonwoven bags. Background Technology

[0002] Non-woven bags are an eco-friendly product, known for their durability, attractive design, good breathability, reusability, washability, ability to be screen-printed with advertisements and labels, and long service life. However, during the production process, damage to non-woven bags is inevitable due to mechanical failures or human error. Damaged bags are unusable and need to be recycled for remanufacturing. Therefore, damaged and discarded non-woven bags must be removed during production.

[0003] Currently, waste removal in nonwoven fabric production still relies on manual labor or inefficient mechanical devices, which cannot quickly detect and remove damaged nonwoven fabric. There is a lack of a standardized solution specifically designed for the characteristics of nonwoven bag production lines that can efficiently and accurately remove waste online. Therefore, there is an urgent need to design a device that can automatically remove waste during the nonwoven bag production process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic waste removal device for non-woven bags.

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

[0006] An automatic waste removal device for non-woven bags includes a base, an outer shell fixedly installed on the upper end of the base, a controller fixedly installed on the outside of the outer shell, an adsorption mechanism provided on the upper end of the outer shell, a discharge trough and a detection trough opened at both ends of the outer shell, a connecting plate fixedly installed at the end of the outer shell with the detection trough, and a waste removal mechanism provided on the connecting plate.

[0007] Preferably, the adsorption mechanism includes a hydraulic cylinder and a first air pump fixedly mounted on the upper end of the outer shell. The output end of the hydraulic cylinder is fixedly connected to a movable plate. An air chamber is opened inside the movable plate. The air chamber is provided with a plurality of evenly distributed air holes. The output end of the first air pump is fixedly connected to the air chamber through a first corrugated pipe.

[0008] Preferably, a plurality of hollow suction cups are fixedly provided at the lower end of the movable plate, and the upper opening of the suction cups corresponds to the opening of the air chamber.

[0009] Preferably, the waste-kicking mechanism includes an electric push rod, a second air pump, and a third air pump, with a detection block fixedly connected to the output end of the electric push rod.

[0010] Preferably, an airbag is fixedly provided on the outer wall of the detection block, and the airbag is fixedly connected to the output end of the second air pump through a second corrugated pipe.

[0011] Preferably, the detection block has an air groove inside, the air groove is fixedly connected to the output end of the third air pump through a third corrugated pipe, and a pressure sensor is fixedly installed inside the air groove.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. In this device, the adsorption mechanism and the waste removal mechanism work together to lift the non-woven bags on the conveyor belt for inspection. The opening of the non-woven bag is sealed by an airbag, and then air is introduced into the sealed non-woven bag by a third air pump to detect whether there is any damage inside the non-woven bag. This realizes the simultaneous detection of damage on each side of the non-woven bag, and improves the accuracy of non-woven bag waste identification.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 An automatic waste removal device for non-woven bags includes a base 1, a housing 2 fixedly installed on the upper end of the base 1, a controller 19 fixedly installed on the outside of the housing 2, an adsorption mechanism provided on the upper end of the housing 2, a discharge trough and a detection trough opened at both ends of the housing 2, a connecting plate 9 fixedly installed on the end of the housing 2 with the detection trough, and a waste removal mechanism provided on the connecting plate 9.

[0026] The adsorption mechanism includes a hydraulic cylinder 3 and a first air pump 5 fixedly mounted on the upper end of the outer shell 2. The output end of the hydraulic cylinder 3 is fixedly connected to a movable plate 4. An air chamber 8 is opened inside the movable plate 4. The air chamber 8 is provided with a number of evenly distributed air holes. The output end of the first air pump 5 is fixedly connected to the air chamber 8 through a first corrugated pipe 6.

[0027] Several hollow suction cups 7 are fixedly installed at the lower end of the movable plate 4, and the upper opening of the suction cups 7 corresponds to the opening of the air chamber 8.

[0028] The waste removal mechanism includes an electric push rod 10, a second air pump 12, and a third air pump 15. A detection block 11 is fixedly connected to the output end of the electric push rod 10. Through the cooperation of the adsorption mechanism and the waste removal mechanism, the non-woven bags on the conveyor belt can be lifted for inspection. An airbag 14 seals the opening of the non-woven bag, and then the third air pump 15 introduces air into the sealed non-woven bag to detect any damage inside. This allows for simultaneous detection of damage on all surfaces of the non-woven bag, improving the accuracy of non-woven bag waste identification.

[0029] An airbag 14 is fixedly installed on the outer wall of the detection block 11, and the airbag 14 is fixedly connected to the output end of the second air pump 12 through the second corrugated pipe 13.

[0030] The detection block 11 has an internal air groove 17, which is fixedly connected to the output end of the third air pump 15 via a third corrugated pipe 16. A pressure sensor 18 is fixedly installed inside the air groove 17. The controller 19 identifies the current damage status of the nonwoven bag based on the pressure applied to the pressure sensor 18 and performs corresponding operations accordingly. This enables automated rejection of damaged nonwoven bags, improving the efficiency of automatic waste removal.

[0031] In this invention, during the production of nonwoven bags, the produced nonwoven bags are conveyed to the waste removal device via a conveyor belt. When the nonwoven bag reaches directly below the movable plate 4, the controller 19 activates the hydraulic cylinder 3. The activation of the hydraulic cylinder 3 causes the movable plate 4 to move downward, causing the movable plate 4 to drive several suction cups 7 to move synchronously until the lower end of the suction cups 7 is in contact with the surface of the nonwoven bag. At this time, the controller 19 activates the first air pump 5, which extracts the air from the air chamber 8 opened in the movable plate 4 through the first corrugated pipe 6. At this time, the air chamber 8 is in a negative pressure state. Since the several openings in the air chamber 8 correspond to several suction cups 7 at the lower end of the movable plate 4, the bottom of the suction cup 7 is in contact with the surface of the nonwoven bag, which in turn causes the inside of the suction cup 7 to be in a negative pressure state, thereby causing the nonwoven bag to be adsorbed at the lower end of the suction cup 7. At this time, the controller 19 drives the hydraulic cylinder 3 to reset, thereby causing the non-woven bag to be lifted by the suction cup 7. After the hydraulic cylinder 3 drives the suction cup 7 to reset, the controller 19 will start the electric push rod 10. The start of the electric push rod 10 will push the detection block 11 to move towards the opening of the non-woven bag until the airbag 14 on the detection block 11 is completely inside the non-woven bag. At this time, the controller 19 will start the second air pump 12. The second air pump 12 will deliver air to the airbag 14 through the second corrugated pipe 13. The airbag 14 will expand under the action of air. During this process, the second air pump 12 will continuously pump air into the airbag 14 until the outer wall of the airbag 14 expands to contact the inner wall of the non-woven bag, so that the airbag 14 seals the opening of the non-woven bag. At this time, the controller 19 will start the third air pump 15. The third air pump 15 will pump gas at a fixed pressure into the air groove 17 inside the detection block 11 through the third bellows 16. Since the air bag 14 seals the opening of the non-woven bag, the inside of the air groove 17 and the inside of the non-woven bag form a sealed space. When the third air pump 15 pumps air into the air groove 17, there will be a certain pressure in the space between the air groove 17 and the inside of the non-woven bag. At this time, the pressure sensor 18 installed inside the air groove 17 will detect the pressure. When the pressure reaches the preset value, it proves that the non-woven bag has not been damaged. If there is a gap in the non-woven bag, the air in the air groove 17 and the inside of the non-woven bag will flow out through the gap. At this time, the pressure detected by the pressure sensor 18 will not reach the preset value.

[0032] When the pressure detected by the pressure sensor 18 does not reach the preset value, the controller 19 will activate the first air pump 5, which will pump air into the suction cup 7 and the air chamber 8, causing the suction cup 7 to release its adhesion to the surface of the non-woven bag. At the same time, the controller 19 will activate the electric push rod 10, which will continue to push the detection block 11 until the detection block 11 pushes the non-woven bag to the outside of the discharge slot on the outer shell 2. At this point, the worker can remove the damaged non-woven bag.

[0033] When the air pressure inside the air tank 17 and the nonwoven bag reaches a preset value, it indicates that the nonwoven bag is intact. At this time, the controller 19 will start the second air pump 12, which will extract the air from the air bag 14. The air bag 14 will then return to its original size and cease its sealing effect on the opening of the nonwoven bag. Then, the controller 19 will start the electric push rod 10 to reset, causing the electric push rod 10 to move the detection block 11 to the outside of the nonwoven bag. At this time, the controller 19 will start the first air pump 5, which will pump air into the suction cup 7 and the air chamber 8, causing the suction cup 7 to release its adhesion to the surface of the nonwoven bag. The nonwoven bag will then fall onto the conveyor belt and be transported to the next production step.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
