AI Technical Summary
In the existing carton side flap sealing machine, the sealing plate is prone to flipping outward due to gravity during the sealing process, which makes it impossible for the sealing pressure plate to be fully pushed back, resulting in sealing failure.
The carton is fixed in position by a limiting mechanism, and the sealing edge plate is tilted down to form a 40° angle with the side of the carton. The first driving mechanism drives the sealing edge plate to tilt down and press the flip-top so that its lower edge fits the board to be sealed, thus avoiding crushing of the sealing edge.
This effectively prevents the edge sealing plate from crushing the top cover and the plate to be sealed, ensuring the smooth completion of the edge sealing process.

Description
TECHNICAL FIELD
[0001] The utility model relates to carton packaging field especially carton side automatic edge sealing machine of upper cover. BACKGROUND
[0002] Full-automatic carton sealing machine seals the side box mouth of carton, and the limiting mechanism fixes the position of carton, and the edge sealing pressing plate vertically presses the upper cover of the side box mouth, and the upper cover is lowered to the sealing plate that is attached to the side box mouth of carton, and the side box mouth is sealed. The sealing plate is generally opened outward at a certain angle under the action of gravity, and the upper cover is lowered to cause the upper cover and the sealing plate to be crushed, and the crushing refers to the situation that the sealing plate is not pushed back inward by the edge sealing pressing plate, and the sealing plate is not sealed as a whole or partially. SUMMARY
[0003] The utility model provides a kind of carton side upper cover automatic edge sealing machine, which can improve the situation that the sealing plate hinders the edge sealing pressing plate to press the upper cover and causes the sealing plate and the upper cover to be crushed when sealing the side of carton.
[0004] To solve the above technical problems, the utility model provides a kind of carton side upper cover automatic edge sealing machine, which includes a limiting mechanism that fixes the position of the carton to be sealed, an edge sealing pressing plate and a first driving mechanism. The edge sealing pressing plate is driven by the first driving mechanism to press the upper cover of the side box mouth of the carton to be sealed. The edge sealing pressing plate faces the side of the carton and is inclined to press the upper cover of the side of the carton, so that the upper cover is lowered to the sealing plate that is attached to the side box mouth of the carton.
[0005] Further, the angle α between the direction of the edge sealing pressing plate and the side of the carton to be sealed is 40°.
[0006] Further, the first driving mechanism is a pneumatic cylinder.
[0007] Further, the limiting mechanism is connected to a second driving mechanism, and the driving mechanism drives the limiting mechanism to be attached to the surface of the carton other than the side to be sealed.
[0008] Further, the second driving mechanism is a pneumatic cylinder.
[0009] The carton side upper cover automatic edge sealing machine provided by the utility model has the following advantages: before sealing the side of the carton, glue is applied to the sealing plate of the carton, and then the limiting mechanism fixes the position of the carton. The edge sealing pressing plate is inclined to press the upper cover of the carton, so that the upper cover is lowered to the sealing plate of the carton to seal the sealing plate. Because the edge sealing pressing plate is inclined, the sealing plate that is turned outward at a certain angle can be pushed back inward when the edge sealing pressing plate is inclined to press the upper cover, so that the upper cover and the sealing plate are not crushed.

DETAILED DESCRIPTION
[0016] The present invention will be further described in detail below in combination with the specific embodiments.
[0017] The carton side flap automatic edge sealing machine is shown in Figure 1 , the front part of the machine frame (not shown in the figure) is provided with a limiting mechanism 3, and the rear part is provided with an edge sealing mechanism 2. The carton 1 is fed from the front of the edge sealing machine, the side to be sealed of the carton 1 is vertical, the limiting mechanism 3 fixes the position of the carton 1, and then the edge sealing mechanism 2 seals the side to be sealed, the process is described in detail below.
[0018] The rear part of the machine frame is inclined forward and downward and extends side by side with three first driving mechanisms 42, the first driving mechanisms 42 used in this specific embodiment are all air cylinders, and each of the three first driving mechanisms 42 drives a first telescopic rod 23 to extend and retract, thereby driving the connection of the edge sealing pressing plate 21, and the first telescopic rod 23 is specifically connected to the fixed part 22 on the back of the edge sealing pressing plate 21. As shown in Figure 5 , the included angle between the first telescopic rod 23 and the front surface of the edge sealing pressing plate 21 is 40°, the edge sealing pressing plate 21 faces the side to be sealed of the carton 1, and the front surface of the edge sealing pressing plate 21 is parallel to the side to be sealed of the carton 1, so the included angle between the direction of the first telescopic rod 23 driving the edge sealing pressing plate 21 to tilt and press downward and the side to be sealed of the carton 1 is 40°. As shown in Figure 1As shown, three second drive mechanisms 43 extend downward from the front of the frame to connect to the limiting mechanism 3. In this specific embodiment, the second drive mechanisms 43 are all cylinders. Each of the three second drive mechanisms 43 drives a second telescopic rod 32 to extend and retract, thereby driving the connection to the lower pressure plate 31, specifically connected to the upper surface of the lower pressure plate 31.
[0019] When the cardboard box 1 reaches the expected position, the three second drive mechanisms 43 simultaneously drive their respective second telescopic rods 32 to extend, causing the lower pressure plate 31 to descend and press against the upper surface of the cardboard box 1. Figure 2 As shown, fix the position of carton 1. Then, as... Figure 3 As shown, the three first drive mechanisms 42 simultaneously drive their respective first telescopic rods 23 to extend. The extension of the first telescopic rods 23 causes the sealing plate 21 to tilt and descend, approaching the upper flap 11 of the side opening of the carton 1 to be sealed. There is a sealing plate 12 on the side opening of the carton 1 to be sealed, which will open outward at a certain angle under the action of gravity. Figure 4 As shown, the first drive mechanism 42 continues to drive the first telescopic rod 23 to extend, and the sealing pressure plate 21 tilts down from the upper part of the side of the carton 1 to be sealed, pressing down on the upper flap 11 of the carton opening. The upper flap 11 lowers and pushes the plate 12 to be sealed, which has an outward turning angle within a certain range, back inward to complete the sealing, avoiding the sealing pressure plate 21 from pressing down vertically and crushing the upper flap 11 and the plate 12 to be sealed. After the side of the carton 1 is sealed, the three first drive mechanisms 42 simultaneously drive each of the first retraction rods 23 to retract, causing the sealing mechanism 2 to tilt upward and reset along its original downward path. Then, the three second drive mechanisms 43 simultaneously drive each of the second retraction rods 32 to retract, causing the limiting mechanism 3 to rise and reset along its original downward path. Subsequently, the carton 1 with the side sealed leaves the sealing machine, a new carton is fed, and the sealing machine repeats the above operation.
[0020] like Figure 5 As shown, the angle α between the first telescopic rod 23 and the side of the carton 1 to be sealed is 40°, that is, the angle at which the sealing plate 21 tilts down is 40°. When the outward folding angle of the board to be sealed 12 does not exceed 31°, the sealing plate 21 tilts down at an angle of 40° to avoid crushing the board to be sealed 12 and the upper flip cover 11.
[0021] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
