[0021] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the present invention in combination with the accompanying drawings and the descriptions of the embodiments or the prior art. Obviously, the following descriptions of the structures of the accompanying drawings are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but do not constitute a limitation to the present invention.
[0022] First embodiment: As Figures 1-6 shown, the embodiment of the present invention provides a hotel self-service integrated machine based on big data information operation and maintenance, including a self-service machine body 1. A pick-up platform 4 is fixedly installed outside the self-service machine body 1. The pick-up platform 4 is located below the inner support housing 320, which is convenient for customers to pick up the packaged text. A printing device 2 is installed inside the self-service machine body 1, which is used to print invoices or other texts. Customers select printing items through the self-service machine body 1 and then print through the printing device 2. A packaging mechanism 3 is connected to the outside of the printing device 2, which is used to package the printed text for the convenience of customers to save. The packaging mechanism 3 includes a slide groove 322 for collecting the printed text. A triangular groove 37 is opened at the bottom of the slide groove 322. The bottom end of the document is inserted into the bottom of the triangular groove 37, so that the bending angle of the bottom of the document paper is limited and the bending angle is small, that is, the triangular groove 37 has a certain function of sorting the documents. A slide-mounted air chamber 38 for driving the printed text to move is installed inside the slide groove 322. A linear displacement mechanism is installed outside the air chamber 38 to push the text towards the packaging mechanism 3.
[0023] Specifically, an inner support housing 320 is installed at the bottom of the chute 322 in a communicating manner. A packaging bag 321 for packaging printed text is slidably sleeved outside the inner support housing 320. The packaging bag 321 can be an envelope. A piston plate 39 is slidably installed inside the air chamber 38. A plurality of nozzles 316 are installed at the bottom of the air chamber 38 in a communicating manner. When the piston plate 39 is extruded, the air inside the air chamber 38 is sprayed from the nozzles 316 towards the inner support housing 320, causing the packaging bag 321 to separate from the inner support housing 320. The frictional force between the packaging bag 321 and the inner support housing 320 is greater than the sum of the gravity of the packaging bag 321 and the printed text. Without external interference, the packaging bag 321 will not separate from the inner support housing 320, ensuring the installation stability of the packaging bag 321.
[0024] In this embodiment, the customer operates the self-service machine body 1 to select the item to be printed. The printing device 2 performs printing. The printed text slides towards the chute 322. The bottom end of the document is inserted into the bottom of the triangular groove 37, restricting the bending angle of the bottom of the document paper to be relatively small. That is, the triangular groove 37 has a certain function of sorting the documents. After all the documents are printed, the linear displacement mechanism drives the document paper to fall to the inner support housing 320. When the piston plate 39 continues to move and is blocked by an external force, the air inside the air chamber 38 is extruded and sprayed towards the inner support housing 320 through the nozzles 316, increasing the force on the packaging bag 321. The packaging bag 321 and the document fall together to the pick-up platform 4, and the customer can directly take away the packaging bag 321 containing the text, effectively preventing the document from being damaged during the customer's subsequent journey, and eliminating the need for staff assistance in packaging, reducing the service workload of the hotel and improving the customer service experience.
[0025] Specifically, a motor 317 is fixedly installed inside the self-service machine body 1. A collar 318 is fixedly installed at the output end of the motor 317. The motor 317 is used to drive the collar 318 to rotate. A plurality of through holes 319 are formed through the outer side of the collar 318. The inner support housing 320 is fixedly installed outside the collar 318, and the inner support housing 320 is in communication with the through holes 319.
[0026] Specifically, a collection column 31 is rotatably installed inside the collar 318. The air chamber 38 is formed inside the collection column 31. A document inlet 34 communicating with the top of the air chamber 38 is formed at the top of the collection column 31. A document outlet 35 communicating with the bottom of the air chamber 38 is formed at the bottom of the collection column 31. A collection pipe 32 communicating with the outlet of the printing device 2 is fixedly installed outside the collection column 31, and the collection pipe 32 is in communication with the document inlet 34.
[0027] In this embodiment, the printed text slides from the collection pipe 32 and the document inlet 34 towards the chute 322, and then under the push of the linear displacement mechanism, moves to the document outlet 35 and slides down to the inner support housing 320 under the action of gravity; The motor 317 rotates a certain angle so that the next set of inner support shells 320, the packaging bag 321 and the document outlet 35 are connected and cooperated.
[0028] Second Embodiment: As Figures 1-6 shown, an embodiment of the present invention provides a hotel self-service integrated machine for information operation and maintenance based on big data, including a self-service machine body 1. A pick-up platform 4 is fixedly installed outside the self-service machine body 1. The pick-up platform 4 is located below the inner support shell 320, which is convenient for customers to pick up the packaged text. A printing device 2 is installed inside the self-service machine body 1 for printing invoices or other texts. Customers select printing items through the self-service machine body 1 and then print through the printing device 2. A packaging mechanism 3 is connected to the outside of the printing device 2 for packaging the printed text to facilitate customer storage. The packaging mechanism 3 includes a chute 322 for collecting the printed text. A triangular groove 37 is opened at the bottom of the chute 322. The bottom end of the document is inserted into the bottom of the triangular groove 37, so that the bending angle of the bottom of the document paper is limited and the bending angle is small. That is, the triangular groove 37 has a certain function of sorting the documents. An air chamber 38 for driving the printed text to move is slidably installed inside the chute 322. A linear displacement mechanism is installed outside the air chamber 38 for pushing the text towards the packaging mechanism 3; The bottom of the chute 322 is connected and installed with an inner support shell 320. A packaging bag 321 for packaging the printed text is slidably sleeved outside the inner support shell 320. The packaging bag 321 can be an envelope; A piston plate 39 is slidably installed inside the air chamber 38. A plurality of nozzles 316 are connected and installed at the bottom of the air chamber 38. When the piston plate 39 is squeezed, the air inside the air chamber 38 is sprayed from the nozzles 316 towards the inner support shell 320, so that the packaging bag 321 is separated from the inner support shell 320. The friction force between the packaging bag 321 and the inner support shell 320 is greater than the sum of the gravity of the packaging bag 321 and the printed text. Without external interference, the packaging bag 321 will not be separated from the inner support shell 320, ensuring the installation stability of the packaging bag 321.
[0029] Specifically, the linear displacement mechanism includes an electric push rod 33. The electric push rod 33 is fixedly installed inside the self-service machine body 1. The telescopic end of the electric push rod 33 is fixedly connected to the air chamber 38. A return spring 311 is fixedly installed between the piston plate 39 and the inner side of the air chamber 38 for driving the piston plate 39 to reset. The piston plate 39 is used to change the air pressure inside the air chamber 38. A limiting column 310 is fixedly installed outside the piston plate 39 for limiting the displacement track of the piston plate 39. The limiting column 310 slidably penetrates the air chamber 38. A limiting plate 312 is fixedly installed at the end of the limiting column 310 exposed outside the air chamber 38 to prevent the piston plate 39 from detaching from the air chamber 38. The return spring 311 is movably sleeved outside the limiting column 310.
[0030] Specifically, a top column 36 is fixedly installed inside the collection column 31. The top column 36 cooperates with the piston plate 39. The top column 36 is used to block the movement of the piston plate 39, so that the air inside the air chamber 38 is squeezed out.
[0031] In this embodiment, when the telescopic end of the electric push rod 33 extends, it drives the air chamber 38 and the piston plate 39 to move towards the top column 36. The movement of the piston plate 39 is blocked by the top column 36, the air inside the air chamber 38 is squeezed, and the return spring 311 is compressed. The air inside the air chamber 38 is squeezed out. When the telescopic end of the electric push rod 33 shortens and resets, it drives the air chamber 38 and the piston plate 39 to reset. The piston plate 39 resets under the elastic force of the return spring 311, and the outside air enters the air chamber 38.
[0032] Specifically, one end of a connecting pipe 313 is fixedly installed and communicated with the outside of the air chamber 38. The other end of the connecting pipe 313 is fixedly installed and communicated with an air pipe 314. A plurality of fixing members 315 are fixedly installed on the outside of the air pipe 314. The fixing members 315 are fixedly installed at the bottom of the air chamber 38. A nozzle 316 is fixedly installed and communicated at the bottom of the air pipe 314. The nozzle 316 faces the inside of the inner support housing 320. The nozzle 316 is used to blow the packaging bag 321 away from the inner support housing 320.
[0033] In this embodiment, the air inside the air chamber 38 is squeezed, and the air inside the air chamber 38 is sprayed from the connecting pipe 313, the air pipe 314, and the nozzle 316 towards the inner support housing 320, so that the force received by the packaging bag 321 increases, and the packaging bag 321 and the documents fall onto the pick-up platform 4 together. When the telescopic end of the electric push rod 33 shortens and resets, it drives the air chamber 38 and the piston plate 39 to reset. The piston plate 39 resets under the elastic force of the return spring 311, and the outside air enters the air chamber 38 from the nozzle 316, the air pipe 314, and the connecting pipe 313.
[0034] Specifically, a disassembly plate 5 is fixedly installed on the outside of the self-service machine body 1 through bolts, which is convenient for the staff to disassemble, repair and maintain the inside of the self-service machine body 1, and is also convenient for replenishing the packaging bags 321.
[0035] In this embodiment, the staff disassemble the disassembly plate 5, then replenish the packaging bags 321, and then reset the disassembly plate 5.
[0036] Specific working mode: The customer manipulates the self-service machine body 1 to select the items to be printed. The printing device 2 performs printing. The printed text slides from the collection tube 32 and the document inlet 34 to the chute 322. The bottom end of the document is inserted into the bottom of the triangular groove 37, so that the bending angle of the bottom of the document paper is limited and the bending angle is small. That is, the triangular groove 37 has a certain function of sorting documents. After all the documents are printed, the telescopic end of the electric push rod 33 extends, driving the air chamber 38 and the piston plate 39 to move towards the top column 36. The air chamber 38 pushes the document paper towards the document outlet 35. The document paper falls from the document outlet 35 to the inner support shell 320. The piston plate 39 continues to move and is blocked by the top column 36. The air inside the air chamber 38 is squeezed, and the return spring 311 is compressed. The air inside the air chamber 38 is sprayed from the connecting pipe 313, the air pipe 314, and the nozzle 316 to the inner support shell 320, so that the force received by the packaging bag 321 increases. The packaging bag 321 and the document fall together to the pick-up platform 4. The customer can directly take away the packaging bag 321 containing the text, which can effectively prevent the document from being damaged during the customer's subsequent journey. Moreover, there is no need for staff assistance in packaging, reducing the service workload of the hotel and improving the customer service experience.
[0037] The telescopic end of the electric push rod 33 shortens and resets, driving the air chamber 38 and the piston plate 39 to reset. The piston plate 39 resets under the elastic force of the return spring 311. External air enters the air chamber 38 from the nozzle 316, the air pipe 314, and the connecting pipe 313. The motor 317 rotates a certain angle, so that the next group of inner support shells 320, packaging bags 321 and the document outlet 35 are connected and matched, and so on.
[0038] After the motor 317 rotates a set number of times, it indicates that the number of remaining packaging bags 321 is insufficient. By flashing the warning light or sending a message to the service desk, the staff is reminded to come and add packaging bags 321. The reminder means can be solved by existing technologies and will not be elaborated in this article. The staff removes the disassembly plate 5, then replenishes the packaging bags 321, and then resets the disassembly plate 5.
[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
