DETAILED DESCRIPTION
[0026] The utility model is further described below in conjunction with the accompanying drawings.
[0027] like Figure 1-6 As shown, an automatic folding mechanism for a corrugated box comprises a main body 1, wherein folding devices 11 are symmetrically installed in the main body 1, wherein a feeding component 12 is provided between the folding devices 11, wherein a pressing component 13 is provided on the top of the feeding component 12, wherein a feeding mechanism 2 is provided at one end of the main body 1, wherein a bracket 3 and a silo 4 are provided in the feeding mechanism 2, wherein a square frame 31 is provided in the bracket 3, wherein a supporting frame 32 is provided in the middle of the square frame 31, wherein a slot 33 is provided on the supporting frame 32, wherein a connecting seat 34 is provided on one side of the bracket 3, wherein a handle 35 is provided at one end of the bracket 3, wherein a bottom plate 41 is provided in the silo 4, wherein side plates 42 are provided on both sides of the bottom plate 41, and wherein a slide rail is provided on the outer wall of the bottom plate 41 43, there are limit blocks 44 at both ends of the slide rail 43, the interior of the square frame 31 and the support frame 32 is set to be hollow, a sliding block 5 is installed at the slot 33, connecting rods 51 are installed on both sides of the sliding block 5, a rotating frame 6 is installed on the top of the connecting rod 51, an opening 61 is provided at one end of the rotating frame 6, a slider 62 is provided on the outer wall of the rotating frame 6, a square hole 7 is opened on the outer wall of one side of the bottom plate 41, a groove 71 is opened on one side of the square hole 7, a square rod 72 is installed inside the square hole 7, a fixing plate 73 is installed on the outer wall of the square rod 72, a sliding rod 8 is installed at one end of the handle 35, an angle gear 81 is installed in the middle of the sliding rod 8, and a screw rod 82 is installed on the right side of the sliding rod 8.
[0028] In the present invention, the pressing component 13 is responsible for pressing the cardboard onto the feeding component 12, and then the feeding component 12 transfers the raw material to the paper folding device 11. The paper folding device 11 processes the cardboard into a paper box. After the device folds the corrugated cardboard into a paper box, the paper box is now located at the edge of the device discharge port. When the next corrugated cardboard is folded into a paper box, the previous product will be pushed out. If the paper box falls directly on the ground, the paper box may be deformed and scattered.
[0029] Combination Figure 1 , Figure 2 , Figure 3 As shown, the bracket 3 is fixedly mounted on the main body 1, and the hollow parts of the square frame 31 and the support frame 32 are connected to each other. The bottom plate 41 is provided with a connecting seat 34 on the outer wall of the side facing the square frame 31, and the bottom plate 41 and the square frame 31 are rotatably connected by a pin passing through the connecting seat 34.
[0030] Furthermore, only one side of the square frame 31 where the handle 35 is installed is hollow, and the hollow part and the support frame 32 are interconnected. The bottom plate 41 and the square frame 31 are installed by aligning the connecting seat 34, and then the pin is used for rotation connection. Figure 1 The middle material bin 4 can be turned over.
[0031] Combination Figure 1 , Figure 2 , Figure 3 As shown, the slide rail 43 and the stop block 44 are located in the middle of the bottom plate 41, and there is a gap between the slide rail 43 and the stop block 44. The slide block 5 is rotatably connected to the connecting rod 51, and the top of the connecting rod 51 is rotatably connected to the rotating frame 6. A pin is installed on the inner wall of the opening 61, and the rotating frame 6 is rotatably connected to the support frame 32 through the pin. A connecting seat 34 is installed on the top of the rotating frame 6, and the connecting seat 34 is rotatably connected to the slider 62, and the slider 62 is slidably connected to the slide rail 43.
[0032] Furthermore, there is a gap between the slide rail 43 and the limit block 44. The gap here is very small to prevent the slider 62 from falling off the slide rail 43. At the same time, the slider 62 is rotatably installed on the rotating frame 6 through the connecting seat 34, so that the slider 62 can move smoothly along the slide rail 43 when the rotating frame 6 rotates.
[0033] It can be seen from the figure that the sliding block 5 is located inside the support frame 32, and it moves along the screw rod 82. The maximum movement or the flipping angle of the silo 4 depends on the length of the slot 33. Because the connection point between the sliding block 5 and the connecting rod 51 is located at the slot 33, the sliding block 5 is provided with a thread that meshes with the screw rod 82 at the point where the screw rod 82 passes through.
[0034] Combination Figure 2 , Figure 3 , Figure 4 As shown, the square hole 7 is connected to the groove 71, the square rod 72 is slidably connected to the square hole 7, and one end of the square rod 72 is connected to the side plate 42. The length of the fixing plate 73 is greater than the groove 71, and the square rod 72 and the fixing plate 73 are provided with threaded holes, in which bolts are installed.
[0035] Furthermore, one end of the square rod 72 is connected to the side plate 42. When the width of the silo 4 needs to be changed, the side plate 42 is pulled out to both sides along the square hole 7 through the square rod 72. After being pulled to a suitable position, the bolts at the fixing plate 73 are screwed, and the fixing plate 73 is squeezed toward the groove 71 through the bolts to play a fixing role.
[0036] Combination Figure 2 , Figure 4 As shown, an angle gear 81 is installed at one end of the screw rod 82, the slide rod 8 is rotatably installed in the square frame 31, and the screw rod 82 is rotatably installed in the support frame 32. The screw rod 82 passes through the sliding block 5, and the slide rod 8 and the angle gear 81 on the screw rod 82 are meshed.
[0037] Furthermore, by turning the handle 35 to drive the slide bar 8 to rotate, the slide bar 8 and the angle gear 81 on the screw rod 82 engage with each other, and then the screw rod 82 rotates accordingly, allowing the sliding block 5 to move along the screw rod 82 .
[0038] The working principle of the utility model is:
[0039] The slide bar 8 is driven to rotate by turning the handle 35. At this time, the slide bar 8 and the angle gear 81 on the screw rod 82 are meshed with each other, so that the screw rod 82 rotates with the slide bar 8, and the sliding block 5 is sleeved on the screw rod 82. At the same time, the sliding block 5 is provided with a thread meshing with the screw rod 82 at the place where the screw rod 82 passes through.
[0040] When the screw rod 82 rotates, the sliding block 5 will move along it. The sliding block 5 is installed inside the support frame 32, and the sliding block 5 will not rotate with the screw rod 82.
[0041] The sliding block 5 moves along the screw rod 82, so the connecting rod 51 supports the rotating frame 6 upward, so that the rotating frame 6 rotates counterclockwise on the support frame 32 based on the pin at the end. The slider 62 is rotatably installed on the top of the rotating frame 6. The slider 62 is slidably installed in the slide rail 43, and the silo 4 will rotate on the square frame 31 with the movement of the rotating frame 6. Figure 1 In the process, the silo 4 will be propped up to form a slope, which can buffer the paper box and can be retracted to reduce the occupied space when not needed.
[0042] When the size of the processed paper box becomes larger, the width of the silo 4 needs to be changed. At this time, first loosen the bolts on the fixed plate 73, pull the side plate 42 to both sides along the square hole 7 through the square rod 72, and the fixed plate 73 moves outside the groove 71 with the square rod 72. When the spacing between the side plates 42 on both sides meets the requirement for the paper box to slide down.
[0043] The bolts at the fixing plate 73 are tightened, and the fixing plate 73 is pressed tightly against the outer wall of the groove 71, so that the side plates 42 on both sides are fixed there.
[0044] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.
