Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a square paper conveying system containing a pusher device. Background Technology

[0002] Square packs of toilet paper are a classic daily necessity. During processing, the rewound large roll of paper is embossed and then rewound onto a wire mesh cage. After a certain number of turns (depending on the number of sheets), it automatically stops. It is then cut by a band saw and laid flat on a large board, where it is further slit into long strips. These strips are then cut into squares by a large back-cutting machine. The squares are then conveyed by a conveyor belt to an automatic packaging machine, where they are packaged into small packets.

[0003] Currently, when the cut square paper is conveyed to the connection point with the packaging machine's feed conveyor belt, misalignment and jamming frequently occur if the connection is not smooth, leading to reduced conveying efficiency. Frequent occurrences of these faults during production can cause the entire conveying system to malfunction, affecting subsequent packaging efficiency and wasting raw paper.

[0004] Therefore, in response to the aforementioned technical problems in the papermaking process, a new type of square paper conveying system still needs to be developed to achieve efficient conveying of square paper to the feeding conveyor belt of the packaging machine. Utility Model Content

[0005] The purpose of this invention is to provide a paper conveying system containing a pushing device to achieve efficient conveying of paper blocks from the conveyor belt to the feeding conveyor belt of the packaging machine.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A square paper conveying system with a pushing device includes a square paper conveyor belt, a packaging machine feed conveyor belt arranged perpendicular to the conveying direction of the square paper conveyor belt, and a pushing device for pushing square paper on the square paper conveyor belt onto the packaging machine feed conveyor belt; a limiting device for limiting the square paper entering the packaging machine feed conveyor belt is also provided on one side of the packaging machine feed conveyor belt.

[0008] The pushing device includes a pushing support frame located on the side of the square paper conveyor belt, a pushing cylinder located on the pushing support frame, a pushing plate located at the end of the piston rod of the pushing cylinder, and an air blowing assembly located on the pushing support frame for blowing air onto the square paper.

[0009] Furthermore, the pusher support frame is provided with a horizontal tray, which is located at the transition position between the square paper conveyor belt and the packaging machine feed conveyor belt.

[0010] Furthermore, the pallet is equipped with a photoelectric sensor capable of detecting the position of the paper squares. Both the photoelectric sensor and the pusher cylinder are connected to an industrial PLC control system. The photoelectric sensor transmits the sensing information of the paper squares before they reach the pusher plate to the control system, which then controls the pusher cylinder to push them.

[0011] Furthermore, the cylinder body of the pusher cylinder is mounted on the pusher support frame.

[0012] Furthermore, the piston rod end of the pusher cylinder is provided with a fixing block, and the pusher plate is mounted on the fixing block.

[0013] Furthermore, the push plate is provided with multiple push plate grooves to reduce friction and electrostatic adsorption between the square paper and the push plate during the pushing process.

[0014] Furthermore, the air blowing assembly includes an air tube frame and an air blowing tube inserted into it, the air blowing tube being connected to an air supply device. The air supply device is connected to an industrial PLC control system, which can blow air simultaneously with the push plate.

[0015] Furthermore, the air tube is mounted on the pusher support frame, and the air tube frame has an air tube insertion hole. The blowing tube is inserted into the air tube insertion hole and the blowing port is directly opposite the pusher plate.

[0016] Furthermore, the air tube frame has multiple air tube insertion holes from top to bottom, which can be used to adjust the blowing height of the air tube.

[0017] Furthermore, the limiting device includes a limiting support frame and a limiting baffle disposed on the limiting support frame.

[0018] Furthermore, the limiting support frame is provided with a baffle adjustment slide rail, and the limiting baffle is connected to a sliding frame that can be slidably disposed on the baffle adjustment slide rail, so as to facilitate horizontal adjustment of the position of the limiting baffle.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The conveying system of this utility model can accurately push the square paper on the square paper conveyor belt onto the packaging machine feed conveyor belt without deviation through the reasonable layout of the square paper conveyor belt, the packaging machine feed conveyor belt and the pusher device. It can also effectively prevent the paper on the top of the square paper from folding to one side of the pusher plate during the rapid push process, so as to achieve efficient conveying of the square paper on the conveyor belt to the packaging machine feed conveyor belt.

[0021] (2) This utility model sets two traditional conveyor belts in a staggered and vertical arrangement, installs a pusher at the junction, and with the assistance of the limiting device, pushes the square paper onto the feeding conveyor belt of the packaging machine without deviation, reducing the occurrence of square paper deviation and jamming on the conveyor belt.

[0022] (3) The present invention can effectively prevent the square paper from folding during the pushing process through the ingenious design of the air blowing component, which can reduce the scrap of the original paper and improve the efficiency and quality of packaging.

[0023] (4) The conveying system of this utility model senses the position of the square paper through photoelectric sensor and realizes the automated pushing process with the assistance of cylinder, which further improves the efficient conveying of the square paper to the feeding conveyor belt of the packaging machine.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] Example 1:

[0035] A square paper conveying system containing a pusher device, such as Figure 1 As shown, the system includes a paper block conveyor belt 1, a packaging machine feed conveyor belt 2, and a packing device 3. The packaging machine feed conveyor belt 2 is arranged perpendicular to the conveying direction of the paper block conveyor belt 1. The packing device 3 is used to push the paper blocks on the paper block conveyor belt 1 onto the packaging machine feed conveyor belt 2. A limiting device 4 is also provided on one side of the packaging machine feed conveyor belt 2 to limit the paper blocks entering the packaging machine feed conveyor belt 2.

[0036] The pushing device 3 specifically includes a pushing support frame 31 located on the side of the square paper conveyor belt 1, a pushing cylinder 32 located on the pushing support frame 31, a pushing plate 33 located at the end of the piston rod of the pushing cylinder 32, and an air blowing assembly 34 located on the pushing support frame 31 for blowing air onto the square paper.

[0037] Before the square paper on the square paper conveyor belt 1 reaches the baffle 33 of the pushing device 3, the pushing cylinder 32 is activated. The baffle 33 is pushed out by the piston rod of the pushing cylinder 32, which can accurately push the square paper onto the feeding conveyor belt 2 of the packaging machine and limit it by the limiting device 4. In addition, since the rapid pushing process may cause the top of the square paper to fold towards the pushing plate 33, the blowing assembly 34 can blow air onto the square paper to blow the folded upper paper back to its original position, and then push it onto the feeding conveyor belt 2 of the packaging machine by the pushing plate 33.

[0038] Example 2:

[0039] A square paper conveying system with a pushing device includes a square paper conveyor belt 1, a packaging machine feed conveyor belt 2, a pushing device 3, and a limiting device 4. Specifically, the pushing device 3 includes a pushing support frame 31 located on the side of the square paper conveyor belt 1, a pushing cylinder 32 located on the pushing support frame 31, a push plate 33 located at the end of the piston rod of the pushing cylinder 32, and an air blowing assembly 34 located on the pushing support frame 31 for blowing air onto the square paper.

[0040] The difference from Embodiment 1 is that, in this embodiment, the push-pack support frame 31 is provided with a horizontal tray 311. The tray 311 is mounted on a tray fixing plate 312 fixedly mounted on the push-pack support frame 31, and the tray 311 is located at the transition position between the square paper conveyor belt 1 and the packaging machine feed conveyor belt 2. The tray 311 is also provided with a photoelectric sensor 35 capable of sensing square paper. The cylinder body of the push-pack cylinder 32 is mounted on the push-pack support frame 31, and the piston rod end of the push-pack cylinder 32 is provided with a fixing block 36. The push plate 33 is mounted on the fixing block 36. Figure 2 As shown, the pusher plate 33 of this embodiment has multiple pusher grooves 331 to reduce friction and electrostatic adsorption between the paper block and the pusher plate 33 during the pushing process, thereby further improving the conveying efficiency.

[0041] In this embodiment, both the photoelectric sensor 35 and the pusher cylinder 32 are connected to the industrial PLC control system. The photoelectric sensor 35 can transmit the sensing information of the square paper before it reaches the pusher plate 33 to the control system, thereby controlling the pusher cylinder 32 to start pushing. After the long strip of paper is cut into square paper by the large back-cutting machine, it is transported to the tray 311 of the pusher device 3 via the square paper conveyor belt 1. When the photoelectric sensor 35 on the side senses the presence of a product, the pusher cylinder 32 pushes the pusher plate 33, so that the square paper can be pushed onto the feeding conveyor belt 2 of the packaging machine without deviation.

[0042] Example 3:

[0043] A square paper conveying system with a pushing device includes a square paper conveyor belt 1, a packaging machine feed conveyor belt 2, a pushing device 3, and a limiting device 4. Specifically, the pushing device 3 includes a pushing support frame 31 located on the side of the square paper conveyor belt 1, a pushing cylinder 32 located on the pushing support frame 31, a push plate 33 located at the end of the piston rod of the pushing cylinder 32, and an air blowing assembly 34 located on the pushing support frame 31 for blowing air onto the square paper.

[0044] The difference from Embodiment 2 is that the air blowing assembly 34 in this embodiment includes an air tube frame 341 and an air blowing pipe 342. The air blowing pipe 342 is connected to an air pump, which is also connected to a PLC control system, allowing air blowing to be performed while pushing the square paper. The air tube frame 341 is mounted on the pusher support frame 31, and the air tube frame 341 has an air tube insertion hole 3411. The air blowing pipe 342 is inserted into the air tube insertion hole 3411, with the air blowing port of the air blowing pipe 342 facing the pusher plate 33, so as to blow air onto the square paper in front of the pusher plate 33 and prevent the square paper from folding to one side of the pusher plate 33 during the rapid pusher process. In addition, as Figure 2 As shown, the trachea frame 341 of this embodiment has multiple trachea insertion holes 3411 from top to bottom, which can be used by the blowing tube 342 to select a suitable height for the trachea insertion hole 3411.

[0045] Example 4:

[0046] A square paper conveying system with a pushing device includes a square paper conveyor belt 1, a packaging machine feed conveyor belt 2, a pushing device 3, and a limiting device 4. Specifically, the pushing device 3 includes a pushing support frame 31 located on the side of the square paper conveyor belt 1, a pushing cylinder 32 located on the pushing support frame 31, a push plate 33 located at the end of the piston rod of the pushing cylinder 32, and an air blowing assembly 34 located on the pushing support frame 31 for blowing air onto the square paper.

[0047] The difference from Embodiment 1 is that the side of the packaging machine feed conveyor belt 2 in this embodiment is provided with a limiting device 4, which is used to limit the square paper entering the packaging machine feed conveyor belt 2 to ensure that the square paper is pushed onto the packaging machine feed conveyor belt 2 without deviation. The limiting device 4 includes a limiting support frame 41 and a limiting baffle 42 provided on the limiting support frame 41. The limiting baffle 42 is vertically arranged along the conveying direction of the packaging machine feed conveyor belt 2. In order to flexibly adjust the position of the limiting baffle 42 according to actual production needs, the limiting support frame 41 is also provided with a baffle adjusting slide rail 43. The limiting baffle 42 is connected to a sliding frame 44 that can slide on the baffle adjusting slide rail 43. The bottom of the sliding frame 44 is correspondingly provided with a slider that can slide on the baffle adjusting slide rail 43.

It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort.
