[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 A carton sealing device for a carton packaging machine includes a transmission table 1, with columns 2 fixedly mounted on both sides of the transmission table 1. A sliding groove 3 is formed on the facing surfaces of the two columns 2. A mounting plate 4 is slidably mounted vertically above the transmission table 1, with both sides of the mounting plate 4 extending into the sliding groove 3. A drive assembly 5 for driving the mounting plate 4 to move vertically is located within the sliding groove 3. An adhesive tape assembly 6 is fixedly mounted on one side of the mounting plate 4, and an auxiliary folding assembly is located on the other side. The drive assembly 5 is existing technology and can use an electric actuator, which is quite common and will not be described in detail.

[0023] The auxiliary folding assembly includes a pressure plate 7 fixedly installed in the middle of the side of the mounting plate 4 facing away from the tape assembly 6. Auxiliary rods 8 are symmetrically arranged on both sides of the pressure plate 7. A slide rail 9 is fixedly installed on the top surface of the mounting plate 4. An L-shaped baffle 10 is slidably arranged on the slide rail 9, and the baffle 10 extends to the side facing away from the tape assembly 6.

[0024] This carton packaging machine uses a carton sealing device. During operation, the operator places the carton on the transmission table 1. The carton first encounters the baffle 10 on the transmission table 1. At this point, the folded cardboard on one side of the upper part of the carton is folded down by the force of the baffle 10, and the folded cardboard on the other side of the upper part of the carton is folded down by the operator. The carton continues to move on the transmission table 1, and the folded cardboard on both sides of the upper part of the carton is folded down by the force of the auxiliary rod 8, at which point all the folded cardboard on the upper part of the carton is folded. The carton continues to move until it reaches below the tape assembly 6, where the tape assembly seals its edges.

[0025] Reference Figure 4 Because the baffle 10 is relatively long, a reinforcing rib 11 is provided in the middle of the baffle 10 to improve the strength of the baffle 10 and enhance the stability of the device.

[0026] Because the folded board on the side of the carton away from the tape assembly 6 may rebound slightly after being manually released, it may cause it to be squeezed or even flipped over by the baffle 10. To solve the above problem, a triangular auxiliary block 12 is fixedly connected to the end of the baffle 10 away from the tape assembly 6. The auxiliary block 12 limits the slight rebound of the folded cardboard and presses it back to the correct position, thereby improving the practicality of the device.

[0027] Reference Figure 1-3 The transmission table 1 has mounting bases 13 fixedly connected to both sides of the pressure plate 7. The auxiliary rod 8 is rotatably mounted at the bottom of the mounting base 13, and the top of the auxiliary rod 8 is higher than the bottom surface of the mounting base 13. Since the force on the auxiliary rod 8 from the carton is relatively small in actual use, the auxiliary rod 8 can be rotatably mounted at the bottom of the mounting base 13. Under normal working conditions, the auxiliary rod 8 is approximately fixed at the bottom of the mounting base 13 through friction. When adjustment is needed, it can be rotated directly to overcome friction.

[0028] The bottom surface of the pressure plate 7 is inclined, and the inclined bottom end of the pressure plate 7 is flush with the bottom surface of the mounting plate 4. The mounting plate 4 is thus held in place by the pressure plate 7. Its principle is the same as that of the auxiliary block 12.

[0029] Multiple rotating rollers 14 are rotatably mounted on the transmission table 1. Clamping assemblies are symmetrically slidably mounted on both sides of the top surface of the transmission table 1. The bottom end of the clamping assembly extends from the gap between adjacent rotating rollers 14 to the bottom of the transmission table 1, and the synchronous reverse movement of the two clamping assemblies is achieved by a driving method such as a pneumatic guide rail.

[0030] The clamping assembly includes a mounting box 15 that is slidably disposed above the transmission table 1. Both mounting boxes 15 have a transmission belt assembly 16 on their opposing sides for driving the carton to move. The carton is driven to move by the mounting box 15 in conjunction with the transmission belt assembly 16. Compared with the solution of driving the carton to move directly by rotating the roller 14, the stability is better.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
