[0031] As Figure 1 shown, an embodiment of the present utility model provides a cardboard folding device for gift box production, including a base 10, a pressing mechanism 20, an elastic pressing mechanism 30, and a locking mechanism 40; the base 10 is provided with a shaping frame 11 for limiting and folding the cardboard, the shaping frame 11 is of a hollow structure, and the cardboard is folded and shaped under the action of the shaping frame 11; the pressing mechanism 20 includes a mounting frame 21 arranged on the top of the base 10, a driving member 22 arranged on the top of the mounting frame 21, and a folding pressing frame 23, the driving member 22 is connected to the folding pressing frame 23 to drive the folding pressing frame 23 to move in the vertical direction; the elastic pressing mechanism 30 is arranged on the top of the base 10 and is located directly below the folding pressing frame 23, and its working end is located inside the shaping frame 11; the locking mechanism 40 is used to make the working end of the elastic pressing mechanism 30 located below the shaping frame 11; wherein, the pressing mechanism 20 presses the cardboard downward into the shaping frame 11, and cooperates with the elastic pressing mechanism 30 to drive the cardboard to stably descend and fold, and through the locking mechanism 40, the folded cardboard is separated from the inside of the shaping frame 11 so that the operator can take the folded cardboard.

[0032] Among them, the driving member 22 can be installed by using a cylinder, an oil cylinder or an electric cylinder purchased from the market and can be used accordingly.

[0033] In the embodiment of the present utility model, when in use, the cardboard is placed above the shaping frame 11, the driving member 22 is activated, driving the folding pressing frame 23 to move downward in the vertical direction. The folding pressing frame 23 presses the cardboard downward into the shaping frame 11, causing the cardboard to start folding under the action of the shaping frame 11. When the cardboard is pressed into the shaping frame 11 by the folding pressing frame 23, the working end of the elastic pressing mechanism 30 contacts the cardboard, and the cardboard is stably clamped between the folding pressing frame 23 and the working end of the elastic pressing mechanism 30 through the elastic force, so that the cardboard descends and folds stably, ensuring that the cardboard is deformed during the folding process until the elastic pressing mechanism 30 is locked by the locking mechanism 40. At this time, the cardboard is completely folded and shaped, and the cardboard that has been folded and shaped can be taken out to prepare for the next cycle.

[0034] Based on the above solution, as Figure 1 shown, in the embodiment of the present utility model, an anti-slip layer is provided on the outer side of the folding pressing frame 23 to improve the stability of pressing the paper downward.

[0035] Specifically, the bottom of the folding pressing frame 23 is in a long rectangular shape, an anti-slip layer is provided on the outer side of the long rectangular shape, and the corners of the long rectangular shape are 90-degree right angles and match the folding part of the cardboard, so that the anti-slip layer of the long rectangular shape stably contacts the cardboard, improving the stability during descent.

[0036] Specifically, as Figure 2 shown, in the embodiment of the present utility model, the elastic pressing mechanism 30 includes a guide post 31 provided on the top of the base 10, a moving plate 32 slidably arranged on the guide post 31, a guide sleeve 33 provided on the moving plate 32 and guidingly cooperating with the guide post 31, and a pressing frame 34. The pressing frame 34 is provided on the top of the moving plate 32, and a spring 35 is further provided between the base 10 and the guide sleeve 33. The spring 35 is sleeved on the outer surface of the guide post 31. The number of the guide posts 31 can be multiple. For example, in this embodiment, four are taken as an example, and the number and position of the guide sleeves 33 correspond to those of the guide posts 31 one by one, thereby improving the reliability of guiding. At the same time, the number of the springs 35 can also be multiple. For example, in this embodiment, four are taken as an example, and the four springs 35 are dispersedly arranged on the four guide posts 31, thereby improving the stability of the cardboard descending and folding.

[0037] During use, the driving member 22 is activated to drive the folding pressing frame 23 to move downward in the vertical direction. The folding pressing frame 23 presses the cardboard downward into the shaping frame 11, and the cardboard starts to fold. As the cardboard is pressed into the shaping frame 11, the pressing frame 34 gradually contacts and presses the cardboard. At the same time, the folding pressing frame 23 applies a downward pressure to the pressing frame 34 through the paper, causing the moving plate 32 to move downward along the guiding column 31. When the moving plate 32 moves downward, the spring 35 is compressed. Then, the elastic force of the spring 35 is transmitted to the pressing frame 34 through the moving plate 32, ensuring that the pressing frame 34 continuously applies pressure to the cardboard to keep the cardboard stable during the folding process.

[0038] Specifically, as Figure 3 shown, in the embodiment of the present utility model, the locking mechanism 40 includes a mounting block 41 provided at the bottom of the moving plate 32, a locking buckle 42 rotatably provided on the mounting block 41, a fixed block 43 provided on the base 10, a locking tongue 44 provided on the fixed block 43, and a tension spring 45. The two ends of the tension spring 45 are respectively connected to one side of the mounting block 41 and the locking buckle 42, so that the locking buckle 42 can be buckled on the locking tongue 44. When the locking buckle 42 is buckled with the locking tongue 44, the position of the elastic pressing mechanism 30 is locked, and at this time, it is convenient to take out the folded cardboard.

[0039] During use, as the moving plate 32 moves downward, the mounting block 41 also moves accordingly. At this time, the locking buckle 42 approaches the locking tongue 44 under the action of the tension spring 45 and finally buckles on the locking tongue 44. After the locking buckle 42 is buckled with the locking tongue 44, the position of the elastic pressing mechanism 30 is locked. At this time, the cardboard is also completely folded and shaped under the action of the shaping frame 11, and it can be conveniently taken out by personnel. When the folded cardboard is taken out, the locking buckle 42 is manually or through a mechanical device disengaged from the locking tongue 44. After the locking buckle 42 is disengaged from the locking tongue 44, it returns to the initial position under the action of the tension spring 45. The driving member 22 drives the folding pressing frame 23 to move upward in the vertical direction to the initial position. As the folding pressing frame 23 rises, the compressed state of the spring 35 is released, and the spring 35 returns to the natural state. The restoring force of the spring 35 causes the moving plate 32 to move upward along the guiding column 31 and return to the initial position. The pressing frame 34 rises accordingly and returns to the initial position above the shaping frame 11 to prepare for the next cycle.

[0040] Specifically, as Figure 3 shown, in the embodiment of the present utility model, the mounting block 41 is provided with a mounting groove 411, and the locking buckle 42 and the tension spring 45 are both arranged in the mounting groove 411, so that the locking mechanism 40 is more compact and reduces the occupied space.

[0041] Specifically, as Figure 3 shown, the mounting groove 411 extends from the bottom end of the mounting block 41 along the top direction.

[0042] Specifically, asFigure 3 As shown, in the embodiment of the present utility model, a rotating rod 46 is rotatably arranged in the mounting groove 411. A push plate 47 is arranged on the rotating rod 46 perpendicular to its axis direction. The push plate can abut against the side of the lock catch 42 away from the tension spring 45 to lock and unlock the locking mechanism 40.

[0043] During use, by rotating the rotating rod 46, the push plate 47 pushes the lock catch 42 to disengage it from the lock tongue 44, realizing manual or mechanical unlocking operation, which is convenient for taking out the folded cardboard.

[0044] Specifically, as Figure 2-3 shown, in the embodiment of the present utility model, one end of the rotating rod 46 is connected with a driving part 48. The driving part 48 is arranged on the side of the mounting block 41 away from the mounting groove 411 to achieve more convenient operation.

[0045] During use, the rotating rod 46 is driven to rotate by the driving part 22, and the push plate 47 can abut against the lock catch 42 to realize locking and unlocking operations.

[0046] Among them, the driving part 48 can be installed by using a motor purchased from the market for corresponding use.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered by the scope of the claims of the present utility model.
