AI Technical Summary
Traditional paper folding devices for ceramic jar packaging machines are limited to folding corrugated paper in a single direction, failing to correctly wrap the edges of a brick stack in multiple directions, thus restricting their applicability to whole sheets of corrugated paper.
A paper folding device equipped with transverse and longitudinal folding mechanisms, along with a lifting device, enables multi-directional folding of corrugated paper edges around a brick stack, using cylinders and crank arms to manipulate the folding process.
Enables complete wrapping of the brick stack in all directions, transforming the packaging method from five-sided to two-sided four-corner wrapping, ensuring efficient and comprehensive paper coverage.

[0033] Preferably, the paper taking device includes a paper outlet; the paper outlet faces the packaging area, and a paper outlet channel is formed between the paper outlet and the packaging area; the paper outlet channel is located between the edge pressing device 10 and the conveying device 70.
[0034] Preferably, the conveying device 70 includes two racks 80; both racks 80 are provided with synchronous belts; and the packaging area is located between the two synchronous belts.
[0035] Preferably, the paper folding equipment further comprises a paper standing device 40 and a fourth cylinder 41; the paper standing device 40 is arranged inside the stand 80; and the fourth cylinder 41 drives the paper standing device 40 to move toward the packaging area.
[0036] Preferably, the paper folding device further comprises a motor 71; the motor 71 is arranged on the stand 80; the motor 71 drives the synchronous belt to work.
[0037] Preferably, the paper folding equipment further comprises a protection device 30; the protection device 30 is arranged on the stand 80, and the protection device 30 is located outside of both sides of the packaging area.
[0038] Specifically, the paper folding device in the background art is only applicable to the case where the carton is a whole sheet of corrugated paper 90, that is, the paper folding device can be arranged front and back in the direction of travel of the brick stack 100, and the corrugated paper 90 is folded into a carton. Figure 5 The figure shows a very narrow corrugated paper 90 skin distributed at the four corners of the brick stack 100, which only wraps the four corners and two sides of the brick stack 100. The paper folding device in the background art cannot fold the paper edge in the direction of travel of the brick stack 100, that is, it cannot fold all directions correctly. Using this corrugated paper 90, the brick stack 100 is changed from the traditional "altar-style" five-sided wrapping to two-side four-corner wrapping.
[0039] Specifically, the first cylinder 21 of this embodiment is an extension cylinder, the second cylinder 51 is a rotation cylinder, the third cylinder 1 is an extension cylinder, the fourth cylinder 41 is an extension cylinder, the lifting device 60 is provided with a lifting cylinder, and the protection device 30 is a box protection frame.
[0040] Specifically, two transverse paper folding devices 20 and longitudinal paper folding devices 50 are provided on the two synchronous belts of the present embodiment, for a total of four transverse paper folding devices 20 and longitudinal paper folding devices 50; the four longitudinal paper folding devices 50 are located at the four corners of the packaging area and surround the packaging area; two transverse paper folding devices 20 are arranged between the two longitudinal paper folding devices 50 of the same synchronous belt, and each transverse paper folding device 20 is close to a longitudinal paper folding device 50 one by one.
[0041] Specifically, a box guard is provided on each of the two synchronous belts of the present embodiment, and the box guard on the same synchronous belt is located between the two transverse paper folding devices 20 .
[0042] Specifically, a pressing device 10 is provided below each transverse paper folding device 20 and each box protection frame in this embodiment.
[0043] Specifically, the longitudinal paper folding device 50 of this embodiment includes a crank arm, and the second cylinder 51 is a rotary cylinder. When the second cylinder 51 drives the longitudinal paper folding device 50 to rotate, it drives the crank arm to move toward the end of the packaging area.
[0044] Specifically, the two synchronous belts of this embodiment and the various paper folding devices and box guards arranged thereon are symmetrically distributed, and a hollow area is formed between the two synchronous belts, such as Figure 4 The lifting device 60 is arranged at the bottom of the hollow area and is located in the packaging area, and two synchronous belts transport the brick stack 100 together.
[0045] Specifically, the paper picking device of this embodiment is located outside the conveying device (not shown in the figure). When the lifting cylinder drives the lifting device 60 to lift the brick stack 100 and make the brick stack 100 leave the synchronous belt, the paper picking device sucks the corrugated paper 90 through the paper outlet and places it between the brick stack 100 and the synchronous belt.
[0046] The working process of the origami device of this embodiment is as follows:
[0047] The conveying device 70 conveys the brick stack 100 through the synchronous belt. When the brick stack 100 enters the packaging area, the third cylinder 1 and the fourth cylinder 41 extend out to drive the paper erecting device 40 and the edge pressing device 10 to form a frame structure around the four corners of the brick stack 100. At the same time, the lifting cylinder drives the jacking device 60 to lift the brick stack 100 so that the brick stack 100 leaves the synchronous belt. Then the paper picking device puts the corrugated paper 90 between the brick stack 100 and the synchronous belt through the paper outlet. Then the lifting cylinder drives the jacking device 60 to fall, and the brick stack 100 falls with the jacking device 60 to press the corrugated paper 90 at the four corners.
[0048] Furthermore, when the brick stack 100 is pressing down the corrugated paper 90, the frame formed by the paper erecting device 40 and the edge pressing device 10 makes the four exposed sides and four ears of the corrugated paper 90 stand up, and the rotating cylinder drives the longitudinal paper folding device 50 to rotate and drive the crank arm to fold the corrugated paper 90 with the four front and rear corners and four ears standing up by another 90°, and then wrap the inner sides of the four corners of the brick stack 100, and then the first cylinder 21 extends out to drive the transverse paper folding device 20 to fold the corrugated paper 90 standing up on the left and right by another 90°, and wrap the outer sides of the four corners and both sides of the brick stack 100 to complete the packaging.
[0049] Furthermore, when the packed brick stack 100 is moved to the next station via the synchronous belt, each cylinder is retracted, and the conveying device 70 conveys the next brick stack 100 into the packaging area, and the folding process is repeated.
[0050] Specifically, the paper folding equipment of this embodiment has a compact structure and can complete paper folding in various directions, so that each corrugated paper 90 can eventually wrap the brick stack 100 .
[0051] This embodiment also provides a brick stack conveying system, including the paper folding device of this embodiment.
[0052] The above is a detailed description of the embodiments of a paper folding device and a brick stack conveying system provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
