[0002] The carton sealing machine is mainly suitable for sealing and packaging cartons. It uses sealing tape to seal the cartons. The upper and lower sides can be sealed at the same time. The rotating folding and shaking cover mechanism is a rocker mechanism driven by a cylinder in the carton sealing machine to achieve the action of folding the carton and then shaking the cover.

[0003] When closing cartons, the rotary folding and swinging cover mechanism of traditional carton sealing machines mostly uses a guide pressure plate and a cylinder to drive the pressure plate to move downward to drive the two carton covers perpendicular to the moving direction to fold and close. However, the cylinder has poor continuity when driving the pressure plate downward, and a positioned guide pressure plate is required to fold one side of the cover first, resulting in a more complicated swinging cover structure and poor continuity during operation. Summary of the invention

[0007] Furthermore, a fixing screw is slidably sleeved inside the adjusting connecting plate, and the rear end of the fixing screw is fixed to the front side wall of the supporting plate. A fixing clamp is threadedly sleeved on the fixing screw on the front side of the adjusting connecting plate, which is used to cooperate with the fixing screw to clamp and fix the adjusting connecting plate.

[0008] Furthermore, the two guide connecting plates are arranged to slide in close contact with each other, and adjustment grooves are provided inside the upper and lower ends of the guide connecting plate at one end, and two fixing screws are slidably inserted inside the adjusting grooves, and the inner ends of the two fixing screws are fixed on the inner wall of the guide connecting plate, and one end of the two fixing screws extending to the outside of the guide connecting plate is threadedly sleeved with two fixing clamps.

[0010] Furthermore, the limiting sleeve block is configured as a rectangular sleeve frame that cooperates with the limiting slide plate, the height of the limiting slide plate is greater than the height of the supporting plate, and the fixing screw rod is configured as a horizontally placed "T" shape.

[0011] Furthermore, the two connecting rods are both configured to be "L"-shaped, the diameter and thickness of the box-pressing roller are both greater than the thickness of the connecting rod, and the second fixing screw rod is configured to be a horizontal "T"-shaped.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, by means of continuous reciprocating movement, when sealing the carton, the carton cover is pressed down and folded by the box pressing rollers on both sides, and the sealing and folding are completed quickly. At the same time, during operation, the impact force during pressing is reduced, and the smoothness during operation is ensured, which solves the problems of the existing carton sealing machine's rotary folding cover mechanism with complicated structure, poor operation smoothness and excessive impact force, and greatly improves the practicality of the rotary folding cover mechanism.

[0021] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments.

The output end of the motor 2 rotates through the support plate 1 and is fixed to the side of the support plate 3. An adjusting connecting plate 4 is slidably connected to the support plate 3, and a driving push rod 7 is fixed to the end of the adjusting connecting plate 4 away from the support plate 3. Two relatively placed and adjustable guide connecting plates 8 are provided on the side of the adjusting connecting plate 4 away from the support plate 3. The front side of the driving push rod 7 is slidably inserted in the guide connecting plate 8, and a fixed guide connecting plate 8 is fixed to the side of the guide connecting plate 8 away from the support plate 3. Plate 9, and a limiting slide plate 10 is fixed on the top of the fixed plate 9, the limiting sleeve 11 is set as a rectangular sleeve frame matched with the limiting slide plate 10, the height of the limiting slide plate 10 is greater than the height of the supporting plate 3, and a limiting sleeve 11 is slidably sleeved on the limiting slide plate 10, and a fixing rod 12 is fixed to the rear side of the limiting sleeve 11, and the other end of the fixing rod 12 is fixed to the front side wall of the supporting plate 1, the bottom ends of the two guide connecting plates 8 are fixed with connecting rods 16, and the bottom ends of the connecting rods 16 are fixed with press box rollers 17, and the two connecting rods 16 are set to "L" shape, and the diameter and thickness of the press box rollers 17 are greater than the thickness of the connecting rods 16.

[0023] Specifically, when it is necessary to seal and fold the carton covers, when the carton moves to the point where the two covers are located between the two box-pressing rollers 17, the motor 2 runs, driving the support plate 3 to rotate. When the support plate 3 rotates, the adjusting connecting plate 4 is driven to rotate accordingly. The rotation of the adjusting connecting plate 4 drives the driving push rod 7 to make a circular motion. When the driving push rod 7 moves downward in the circular motion, it can push the guide connecting plate 8 to move downward. At the same time, it drives the limiting slide plate 10 to slide inside the limiting sleeve block 11. When the guide connecting plate 8 moves downward, the box-pressing roller 17 is driven downward through the connecting rod 16, so that the carton covers on both sides can be pressed and folded at the same time to achieve sealing of the box covers. When the driving push rod 7 moves upward, it can drive the box-pressing roller 17 to move upward, and the carton continues to move for packaging.

[0024] As an optimization solution, Figure 3 and Figure 4 As shown, a fixing screw 5 is slidably sleeved inside the adjusting connecting plate 4, and the fixing screw 5 is set to be a horizontally placed "T" shape, and the rear end of the fixing screw 5 is fixed to the front side wall of the supporting plate 3, and a fixing clamp 6 is threadedly sleeved on the fixing screw 5 on the front side of the adjusting connecting plate 4, which is used to cooperate with the fixing screw 5 to clamp and fix the adjusting connecting plate 4, and the two guide connecting plates 8 are relatively slidingly fitted. An adjusting groove 13 is opened inside the upper and lower ends of the guide connecting plate 8 at one end, and a fixing screw 2 14 is slidably inserted inside the adjusting groove 13, and the fixing screw 2 14 is set to be a horizontal "T" shape, and the inner ends of the two fixing screws 2 14 are fixed on the inner wall of the guide connecting plate 8, and the ends of the two fixing screws 2 14 extending to the outside of the guide connecting plate 8 are threadedly sleeved with a fixing clamp 2 15, and the opposite surfaces of the two guide connecting plates 8 are set to cooperate with each other in an "L" shape, and the width of each fixing clamp 2 15 is greater than the width of the adjusting groove 13.

[0025] Specifically, when it is necessary to adjust the distance between the two box-pressing rollers 17 according to the length of the carton, the fixed clamping blocks 15 at the upper and lower ends are turned to release the clamping of the guide connecting plate 8 by the fixed clamping blocks 15, and the guide connecting plate 8 can be pulled to adjust the distance between the two guide connecting plates 8. After the adjustment is completed, the fixed clamping blocks 15 are tightened to fix the two guide connecting plates 8 again. When it is necessary to adjust the downward distance of the box-pressing roller 17 according to the height of the carton, the fixed clamping blocks 6 are turned to release the clamping of the adjusting connecting plate 4 by the fixed clamping blocks 6, and the adjusting connecting plate 4 can be pulled to adjust the distance between the driving push rod 7 and the center of the support plate 3. After the adjustment is completed, the fixed clamping blocks 6 are turned to clamp the adjusting connecting plate 4 again.
