[0022] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" or "communicated with" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "upper", "lower", "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only and do not represent the only embodiment.

[0024] The following will mainly describe the folding device in further detail with reference to the drawings and specific embodiments.

[0025] For a folding device in an embodiment, please refer to Figures 1-3 , the folding device includes: a bracket assembly 01, a carrier 02, a flow guide member 03, and a folding assembly 04.

[0026] The bracket assembly 01 is used to fix the carrier 02, the flow guide 03 and the folding assembly 04.

[0027] In this embodiment, the bracket assembly 01 includes a first bracket 011, a second bracket 012, a third bracket 013 and a fourth bracket 014.

[0028] The carrier 02 is used to carry the panel assembly including the panel to be folded and is fixedly connected to the bracket assembly 01. When the folding device is set on the carton gluing machine, during operation, the panel assembly can move forward on the carrier 02 along with the transmission mechanism of the carton gluing machine.

[0029] The flow guide 03 is arranged above the carrier 02 and is fixedly connected to the bracket assembly 01. A gap is provided between the flow guide 03 and the carrier 02, so that during the operation of the folding device, the panel assembly can move within the gap between the carrier 02 and the flow guide 03.

[0030] In this embodiment, the flow guide 03 is fixedly connected to both the first bracket 011 and the second bracket 012 at the same time.

[0031] The folding assembly 04 is fixedly connected to the bracket assembly 01. The folding assembly 04 is used to fold the panel to be folded forward and then backward.

[0032] In this embodiment, the folding assembly 04 includes a first folding part 041, a deflection belt 042 and a second folding part 042.

[0033] For the first folding part 041, please refer to Figure 2 , the first folding part 041 is fixedly connected to the first bracket 011 and the second bracket 012. The first folding part 041 is arranged on the side of the carrier 02, and its front end gradually transitions from a planar shape to a ">" shape at the rear end. When the panel to be folded moves within the first folding part 041, under the guiding action of the first folding part 041, the panel to be folded will be folded forward from the unfolded state.

[0034] In another embodiment, a first through hole 0411 and a second through hole 0412 are provided at the rear end of the first folding part 041. When the folding device is applied to the carton gluing machine, the first through hole 0411 can be used to set a signal detection device, and the second through hole 0412 is used to set a glue spraying system. When the panel to be folded moves to the first through hole 0411, the signal detection device obtains the detection signal that the panel to be folded reaches the predetermined position and transmits the detection signal to the glue spraying system. When the panel to be folded moves to the second through hole 0412, the nozzle arranged above the second through hole 0412 can spray glue onto the panel from top to bottom.

[0035] Optionally, the signal detection device is a photoelectric sensor. When the photoelectric sensor detects that the light signal is blocked by the panel to be folded, an electrical signal indicating that the panel assembly has reached the predetermined position is sent to the gluing system.

[0036] The deflection belt 042 is fixedly connected to the diversion member 03 at both ends simultaneously, and at least a part of the deflection belt 042 is disposed between the first folding portion 041 and the second folding portion 042. When the panel to be folded comes out of the first folding portion 041, under the guiding action of the deflection belt 042, the panel to be folded will recover from the forward folding to the unfolded state.

[0037] In this embodiment, the deflection belt 042 is a circular metal piece arranged in a curve, and the metal has a smooth surface.

[0038] For the second folding portion 042, please refer to Figure 3 , the second folding portion 042 is fixedly connected to the third bracket 013 and the fourth bracket 014. The second folding portion 042 is disposed on the side of the carrier 02. The second folding portion 042 is obtained by twisting a planar material by a predetermined angle. In this embodiment, the twisting angle is 180 degrees, so that the lower surface of the front end of the second folding portion 042 becomes the upper surface after twisting at the rear end. When the panel to be folded enters the second folding portion 042 through the deflection belt 042, under the guiding action of the second folding portion 042, it changes from the unfolded state to the reverse folding state.

[0039] In another embodiment, the folding device is applied to a box gluing machine, and the reverse side of the panel to be folded

[0040] Under the action of glue, the panel to be folded is fixedly connected to the packaging box body.

[0041] The above folding device can achieve the following beneficial effects by folding the packaging box panel forward and then backward: (1) After the packaging box panel is folded forward, by changing the direction of the panel, the glue spraying from bottom to top is changed to spraying from top to bottom, thus avoiding quality accidents caused by glue dropping onto non-glue-spraying parts and work-related injuries caused by glue spraying into the operator's eyes. (2) By folding the packaging box panel forward and then backward, the paper stress can be greatly reduced, so that the formed packaging box can be easily opened from a planar shape to a three-dimensional shape, thereby improving the machine-packing efficiency.

[0042] A box gluing machine in one embodiment includes any one of the above folding devices.

[0046] In this embodiment, the first folding part 041 is arranged on the side of the stage 02, and its front end gradually transitions from a wide planar shape to a narrow ">" shape at the rear end. The deflection belt 042 is a circular metal arranged in a curve, and at least part of the deflection belt 042 is arranged between the first folding part 041 and the second folding part 042, and the metal has a smooth surface.
