Description

Technical Field

[0001] The utility model relates to the technical field of storage cabinets, in particular to a small-sized flammable and explosive bottle return storage cabinet. Background Art

[0002] Self-spraying pressure-bottled rust removers, rust-removing lubricants, cleaning agents, screw looseners, and self-spraying paints are widely used in various industries, including construction sites, mechanical processing, equipment maintenance, and automobile manufacturing, because they can be sprayed without the use of additional power such as air compressors. They are also small in size, easy to use, and require no other equipment. However, they are flammable and explosive, and pose certain risks when exposed to high temperature and high pressure conditions such as sparks and hot workpieces. Furthermore, due to their small size, frequent use, and ease of use, they are easily overlooked, hidden, and difficult to manage. If a fire or explosion occurs, not only will it cause economic losses and casualties, but it will also be difficult to identify the responsible parties, making it difficult to handle the situation, leading to the frequent occurrence of such accidents.

The returned spray paint will automatically enter the collection bin for the next person to collect.

[0026] When in use, the utility model is a small flammable and explosive bottle return and storage cabinet. When returning a spray paint bottle, if there is no paint in the bottle, it will be placed in the empty bottle recovery bin. The integrity and serial number of the bottle nozzle and other parts will be identified by a CCD camera and a barcode scanner. If the nozzle and other parts are intact, it will automatically detect whether there is any residue. If it is used up, the return will be displayed as a success after the returner performs facial recognition, and the bottle will be automatically collected. If it is not used up, the return will be displayed as a failure after the returner performs facial recognition, and the returner will be reminded to place it in the return bin. Only when the returner places the spray paint bottle in the return bin will a closed loop be formed. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Working principle:

[0050] Initial placement: After operating through the industrial control all-in-one machine 9, the bottom of the bottle is coded by the inkjet printer 13 (the code is unique for each bottle, making it a traceable code for closed-loop management of collection, return, and empty bottle recycling), and then placed in the first storage port 7 of the collection bin 12. Then, after confirmation by the industrial control all-in-one machine 9, the pneumatic XYZ moving platform in the collection bin 12 is operated, and the lifting rodless slider 26 controls the movable plate 32 to rise. The movable plate 32 drives the clamping assembly to rise through the longitudinal rodless slider 31 and the transverse rodless slider 25 until it reaches the setting. Then the transverse rodless slider 25 drives the clamping assembly to move transversely until it reaches the setting. Then the longitudinal rodless slider 31 moves the clamping assembly to the first storage port 7. The clamping cylinder 29 drives the two clamping rods 30 to approach each other to clamp the bottle. Then the pneumatic XYZ moving platform operates and cooperates with the clamping assembly to place the bottle on the corresponding placement rack 24.

[0051] During the initial collection: after confirmation by the industrial control all-in-one computer 9, it is recognized by the face recognition device 10, and then the pneumatic XYZ mobile platform operates in conjunction with the clamping component to place the corresponding bottle in the receiving port 8 of the receiving bin 12, and then the receiving person picks it up;

[0052] After receiving: After the set time of receiving, the voice alarm 6 will sound an alarm to remind the recipient to return it; if it is not returned after multiple reminders, the corresponding APP can be set to notify the administrator and the recipient, and the recipient will be given corresponding penalties according to the set rules, and urged to complete the cancellation of the number after the self-spray paint is returned;

[0053] When returning: If the bottle is not completely used, the code on the bottle is identified by the barcode scanner 38 on the return bin 14, and the bottle is then placed on the positioning slot 20 in the first storage port 7 of the return bin 14. After confirmation by the industrial control all-in-one computer 9 and the face recognition device 10, the pneumatic XYZ moving platform operates in conjunction with the clamping assembly to place the bottle on the corresponding placement rack 34;

[0054] To claim again: proceed as above;

[0055] When returning: if the bottle is used up, the code is identified by the barcode scanner 38 on the empty bottle recovery bin 15, and then the bottle is placed in the positioning slot 20 in the second storage port 4, and then the appearance is visually inspected by the CCD camera 17. If it is incomplete, the voice alarm 6 is used to prompt the person who receives it to take it out; if it is complete, the cylinder 16 is pressed to push the pressing block 18 down, and the pressing end of the bottle is pressed. The CCD camera 17 is used to visually identify whether spray is generated. If spray is generated, the voice alarm 6 is used to prompt the person who receives it to take it out. When fog is generated, the pneumatic XYZ moving platform operates in conjunction with the clamping assembly to place the corresponding bottle between the corresponding set of limit rods 27, and then adjust the position of the telescopic cylinder 28. After completion, the telescopic cylinder 28 pushes the rotating cylinder 36, the mounting block 35 and the hard sharp object 27 to descend, breaking the bottle. Then the telescopic cylinder 28 drives the rotating cylinder 36 and the mounting block 35 to rise. After reaching the set height, the rotating cylinder 36 drives the mounting block 35 to rotate, allowing the extrusion block 34 to face downward. The telescopic cylinder 28 drives the extrusion block 34 to descend through various components until the bottle is flattened.
