Description

Technical Field

[0001] The utility model relates to the technical field of paper bag manufacturing, in particular to a paper humidifying device for a paper bag machine. Background Art

[0002] In the paper bag manufacturing industry, the humidity control of paper plays a crucial role in the quality and production efficiency of paper bags. If the humidity control of paper is ignored, it will cause problems such as cracking and embrittlement of the paper during the processing, affecting the strength and durability of the paper bags. In some small paper bag production workshops, due to the lack of effective humidifying equipment, the produced paper bags are prone to breakage at the folding and binding positions. For example, the Chinese patent document with the publication number CN218203612U discloses a paper humidifying device, which includes a base, a fixed frame fixedly connected to the top of the base, a feeding roller and a winding roller rotatably connected to the outside of the fixed frame respectively, a motor fixedly connected to one side of the fixed frame, the output end of the motor is fixedly connected to one end of the winding roller, a rotating roller is arranged on the top of the base, and a humidifying component is arranged on the top of the base.

For example, it may be a fixed connection, a detachable connection, or an integral one; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0037] As Figures 1 to 4 shown, in one embodiment, a paper humidifying device 1 of a paper bag machine includes a box body 10 and a spray assembly 20. The spray assembly 20 includes a spray pipe 21, an air joint 22, a water joint 23, a driving member 24 and an atomizing nozzle 25. The spray pipe 21 rotates inside the box body 10. An air chamber 211 and a water chamber 212 are formed inside the spray pipe 21. The air joint 22 and the water joint 23 are respectively rotatably arranged at both ends of the spray pipe 21, and the air joint 22 is communicated with the air chamber 211, and the water joint 23 is communicated with the water chamber 212. The atomizing nozzle 25 is arranged on the spray pipe 21, and the atomizing nozzle 25 is communicated with both the air chamber 211 and the water chamber 212, so that the gas in the air chamber 211 and the water in the water chamber 212 can be sprayed out from the atomizing nozzle 25 at the same time. The driving member 24 is arranged on the box body 10, and the driving member 24 is connected with the spray pipe 21. The driving member 24 is used to drive the spray pipe 21 to rotate.

[0038] It should be noted that side plates are provided on both sides of the box body 10 to make the box body 10 a hollow structure. The spray pipe 21 passes through the two side plates of the box body 10 so that the spray pipe 21 penetrates through the inside of the box body 10, and both ends of the spray pipe 21 extend out of the side plates on both sides of the box body 10. An air chamber 211 and a water chamber 212 are formed in the spray pipe 21, and a partition structure is provided between the air chamber 211 and the water chamber 212 to prevent the air chamber 211 and the water chamber 212 from communicating with each other. Further, an air joint 22 and a water joint 23 are respectively rotatably provided at both ends of the spray pipe 21, and the air joint 22 communicates with the air chamber 211, and the water joint 23 communicates with the water chamber 212. It should be noted that both the air joint 22 and the water joint 23 are rotary joints. In this way, when the air joint 22 is connected to an external air pipe, the air chamber 211 can be filled with gas, and when the water joint 23 is connected to an external water pipe, the water chamber 212 can be filled with water. Further, an atomizing nozzle 25 is provided on the spray pipe 21 so that the gas in the air chamber 211 is ejected from the nozzle 252 of the atomizing nozzle 25, and the side of the atomizing nozzle 25 communicates with the water chamber 212 so that the water in the water chamber 212 is ejected from the nozzle 252 of the atomizing nozzle 25. In this way, the gas in the air chamber 211 and the water in the water chamber 212 can be ejected from the nozzle 252 of the atomizing nozzle 25 at the same time. Further, a driving member 24 is provided on the outer wall of one side plate of the box body 10, and the output end of the driving member 24 is connected to one end of the spray pipe 21 extending out of the side plate of the box body 10. In this way, the driving member 24 can drive the spray pipe 21 to rotate.

[0039] As Figures 6 to 9 shown, in one embodiment, the air chamber 211 is provided with a first inlet end 2111 and a first outlet end 2112. The first inlet end 2111 communicates with the air joint 22, and the first outlet end 2112 communicates with the atomizing nozzle 25. The water chamber 212 is provided with a second inlet end 2121 and a second outlet end 2122. The second inlet end 2121 communicates with the water joint 23, and the second outlet end 2122 communicates with the atomizing nozzle 25.

[0040] It should be noted that the air chamber 211 is opened from one end of the nozzle 21 towards the middle direction of the nozzle 21, and the first inlet end 2111 is located at the end of the nozzle 21 and communicates with the air joint 22, while the first outlet end 2112 is located in the middle of the nozzle 21 and communicates with one end of the atomizing nozzle 25. The water chamber 212 is opened from the other end of the nozzle 21 towards the middle direction of the nozzle 21, and the second inlet end 2121 is located at the other end of the nozzle 21 and communicates with the water joint 23, while the second outlet end 2122 is located in the middle of the nozzle 21 and communicates with the atomizing nozzle 25. Further, since both the first outlet end 2112 and the second outlet end 2122 are located in the middle of the nozzle 21, the first outlet end 2112 and the second outlet end 2122 can extend out from the middle of the nozzle 21 closely to each other, so that the first outlet end 2112 and the second outlet end 2122 can jointly communicate with the atomizing nozzle 25. In this way, the gas in the air chamber 211 and the water in the water chamber 212 can be ejected from the nozzle 252 of the atomizing nozzle 25 simultaneously.

[0041] As Figure 10 shown, in one embodiment, the atomizing nozzle 25 includes a nozzle body 251 and a nozzle 252. The nozzle body 251 communicates with both the first outlet end 2112 and the second outlet end 2122. The nozzle 252 is disposed on the nozzle body 251 and communicates with the nozzle body 251. The nozzle body 251 is provided with an air inlet 2511 and an air inlet 2512. The first outlet end 2112 communicates with the air inlet 2511, and the second outlet end 2122 communicates with the air inlet 2512.

[0042] It should be noted that an air inlet 2511 is provided at one end of the spray body 251 away from the nozzle 252, and an air inlet 2512 is provided on the side surface of the spray body 251. Further, the first outlet end 2112 of the air chamber 211 is communicated with the air inlet 2511 of the spray body 251, so that the gas in the air chamber 211 can be ejected from the nozzle 252 of the atomizing nozzle 25 through the air inlet 2511, and the second outlet end 2122 of the water chamber 212 is communicated with the air inlet 2512 of the spray body 251, so that the water in the water chamber 212 can be ejected from the nozzle 252 of the atomizing nozzle 25 through the air inlet 2512. Since both the air inlet 2511 and the air inlet 2512 are communicated with the nozzle 252, thus, the gas in the air chamber 211 and the water in the water chamber 212 can be ejected from the nozzle 252 of the atomizing nozzle 25 simultaneously. Further, spray holes are provided on the nozzle 252, and the spray holes are communicated with the air inlet 2511 and the air inlet 2512. Since the spray holes are set to have a smaller aperture, when the gas is ejected, the air flow velocity near the spray holes is relatively large, and thus a low-pressure area is formed in the area near the spray holes. The air pressure in this low-pressure area is less than the air pressure in the spray body 251. And since the spray holes are also communicated with the air inlet 2512, when the gas is ejected from the nozzle 252, it will drive the water in the spray body 251 into the low-pressure area, and then the water is quickly extruded out of the nozzle 252 by the gas. When the water is quickly ejected from the smaller spray holes, the water will be subjected to strong pressure and friction when being ejected, so that the water flow is broken into fine mist-like water droplets. In this way, the nozzle 252 can uniformly humidify the paper.

[0043] As Figures 6 to 9 shown, in an embodiment, the angle between the spray body 251 and the spray pipe 21 is less than 90 degrees.

[0044] It should be noted that the spray pipe 21 is arranged parallel to the paper surface, and the atomizing nozzle 25 is arranged on the spray pipe 21, and the angle between the atomizing nozzle 25 and the spray pipe 21 is less than 90 degrees, so that the atomizing nozzle 25 sprays the paper surface at an oblique angle, so that the spraying area of the atomizing nozzle 25 is larger than the area sprayed in the vertical direction, and thus the spraying area of the atomizing nozzle 25 can more evenly cover the paper surface.

[0045] As Figure 2 、 Figure 6As shown, in one embodiment, there are two atomizing nozzles 25. For the convenience of description, the two atomizing nozzles 25 are respectively defined as the first atomizing nozzle 25 and the second atomizing nozzle 25. The first atomizing nozzle 25 and the second atomizing nozzle 25 are arranged on both sides of the spray pipe 21 and are close to the inner side walls of the two side plates inside the box body 10. The angle between the first atomizing nozzle 25 and the spray pipe 21 is less than 90 degrees, and the first atomizing nozzle 25 faces the second atomizing nozzle 25. The angle between the second atomizing nozzle 25 and the pipe is less than 90 degrees, and the second atomizing nozzle 25 faces the first atomizing nozzle 25. In this way, oblique-angle spraying and humidifying can be carried out on both sides of the spray pipe 21. Further, the air chamber 211 is further provided with a third outlet end 2113, and the water chamber 212 is further provided with a fourth outlet end 2123, so that the first outlet end 2112 and the second outlet end 2122 are jointly communicated with the first atomizing nozzle 25, and the third outlet end 2113 and the fourth outlet end 2123 are jointly communicated with the second atomizing nozzle 25. When the driving member 24 drives the spray pipe 21 to rotate, the spray pipe 21 drives the two opposite atomizing nozzles 25 to rotate, and the two opposite atomizing nozzles 25 rotate and spray obliquely. In this way, the humidifying effect on the paper is more uniform.

[0046] As Figures 1 to 2 shown, in one embodiment, a plurality of sealing grooves 231 are formed on the water joint 23, and sealing rings are sleeved in the respective sealing grooves 231.

[0047] It should be noted that the respective sealing grooves 231 are formed at one end of the water joint 23 away from the spray pipe 21 to seal the gap after the water joint 23 is clamped with the washing machine water inlet joint 23 and prevent water from leaking out of the interface.

[0048] As Figure 1 shown, in one embodiment, the driving member 24 includes a driving motor 241, a belt 242, a main pulley and a driven pulley 245. The driving motor 241 is arranged on the box body 10, the main pulley is arranged on the output end of the driving motor 241, the driven pulley 245 is arranged on the spray pipe 21, and the belt 242 is sleeved on the main pulley and the driven pulley 245.

[0049] It should be noted that the driving motor 241 is arranged on the outer side wall of one side plate of the box body 10, the main pulley is arranged on the output end of the driving motor 241, the driven pulley 245 is arranged on the spray pipe 21, and the belt 242 is sleeved on the main pulley and the driven pulley 245, so that the driving motor 241 drives the spray pipe 21 to rotate.

[0050] As Figure 1 、 Figures 3 to 4As shown, in one embodiment, there are two nozzle pipes 21 and two follower pulleys 245. For ease of description, the two follower pulleys 245 are respectively defined as the first follower pulley 245 and the second follower pulley 245. The first follower pulley 245 and the second follower pulley 245 are respectively arranged at one end of the two nozzle pipes 21. The belt 242 is sleeved on the main pulley, the first follower pulley 245 and the second follower pulley 245, so that the driving motor 241 drives the two nozzle pipes 21 to rotate. Further, the driving member 24 further includes a limiting wheel. The limiting wheel is arranged on the outer side wall of a side plate of the box body 10, and the limiting wheel is tangent to the first follower pulley 245. When the belt 242 is sleeved on the first follower pulley 245, the limiting wheel pushes one side of the belt 242 to fit with the first follower pulley 245, so as to enable the belt 242 to better drive the first follower pulley 245 and the second follower pulley 245 to rotate.

[0051] As Figure 1 、 Figures 4 to 5 shown, in one embodiment, the paper humidifying device 1 of the paper bag machine further includes a rotating motor 30, a main shaft rod 40, a main gear 50 and a follower gear 60. The rotating motor 30 is arranged on the box body 10. The main shaft rod 40 is rotatably arranged in the box body 10. The main gear 50 is sleeved on the output end of the rotating motor 30. The follower gear 60 is sleeved on the main shaft rod 40, and the main gear 50 meshes with the follower gear 60. The main shaft rod 40 is used to drive the paper to rotate.

[0052] It should be noted that the rotating motor 30 is arranged on the outer side wall of a side plate of the box body 10. The main shaft rod 40 passes through the side plates on both sides of the box body 10, so that the main shaft rod 40 can rotate in the box body 10. When a whole roll of paper is mounted on the main shaft rod 40, the rotating motor 30 drives the paper to rotate through the main shaft rod 40.

[0053] As Figure 4 shown, in one embodiment, the paper humidifying device 1 of the paper bag machine further includes a plurality of guide rods 70. Each guide rod 70 is rotatably arranged in the box body 10, and each guide rod 70 is used to guide the paper to turn towards a "V" shape.

[0054] It should be noted that each guide rod 70 passes through the side plates on both sides of the box body 10, so that each guide rod 70 can rotate within the box body 10, and each guide rod 70 is arranged parallel to the main spindle rod 40. When a whole roll of paper is placed on the main spindle rod 40, the rotating motor 30 will drive the whole roll of paper to rotate, so that the paper is unrolled from the main spindle rod 40, and each guide rod 70 guides the unrolled paper to turn within the box body 10, so that the unrolled paper is flatter. Further, each guide rod 70 guides the paper to turn in a "V" shape. Since there are two spray pipes 21, and the spray pipes 21 are both located at the middle position within the "V" shape, the paper tends to wrap the spray pipes 21, so that the contact area between the mist ejected from the spray pipes 21 and the paper is larger, and thus the humidifying effect is more uniform. And the other spray pipe 21 is located at the middle position outside the "V" shape, so that the other spray pipe 21 can spray and humidify the other side of the paper. In this way, the humidifying effect of the paper is more uniform.

[0055] As Figure 3 shown, in one embodiment, the box body 10 is provided with enclosing plates around it, so as to form a relatively airtight space within the box body 10. When the spray pipe 21 humidifies within the box body 10, the mist can be kept in the airtight space for a long time, so as to avoid the loss of mist resulting in insufficient mist, thus requiring more gas and water resources. In this way, the resource costs of gas and water can be effectively reduced.

[0056] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
