By setting a folding component, the device can automatically fold the carton, solving the problem that existing devices require manual folding of the top cover of the carton before sealing, and the production efficiency of the device is reduced because the speed at which workers fold the carton cannot be kept consistent.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a folding device for a carton sealing machine, comprising a base with support legs fixedly connected to the four corners of the base bottom. Fixed columns are fixedly connected to the front and back of the base. A folding assembly is disposed above the base. The folding assembly includes a second motor, the bottom of which is fixedly connected to the top of the fixed columns. A threaded rod is fixedly connected to the bottom output end of the second motor. The outer surface of the threaded rod is rotatably connected to the inner wall of the fixed columns. A movable rod is threadedly connected to the outer surface of the threaded rod. By setting the folding assembly, manual folding is no longer required when sealing cartons, reducing the workload of workers and improving the sealing efficiency of the device.

[0007] Furthermore, a moving plate is fixedly connected to the end of the moving rod away from the threaded rod, and a pressure rod is fixedly connected to the bottom of the moving plate. There are two pressure rods, and a pressure plate is fixedly connected to the bottom of the two pressure rods. By setting the pressure rods, the top cover of the carton can be pressed flat, which facilitates the sealing of the carton by the device.

[0008] Furthermore, four cylinders are fixedly connected to the bottom of the movable plate. A support plate is fixedly connected to the bottom of the four cylinders, and an electric push rod is fixedly connected to the top of the support plate. A telescopic rod is fixedly connected to the front output end of the electric push rod. By setting the support plate, the electric push rod can operate more smoothly.

[0009] Furthermore, a second fixing block is rotatably connected to the front of the telescopic rod, a second pressure rod is fixedly connected to the front of the second fixing block, a second rotating shaft is fixedly connected to the back of the second pressure rod, a first fixing block is rotatably connected to the outer surface of the second rotating shaft, and the back of the first fixing block is fixedly connected to the front of the moving plate. By setting the second pressure rod, the device can automatically fold the top cover of the carton, thus improving the working efficiency of the device.

[0010] Furthermore, a conveying assembly is provided above the base. The conveying assembly includes a motor. The bottom of the motor is fixedly connected to the top of the base, and a rotating shaft is fixedly connected to the top output end of the motor.

The inner walls of the two outer boxes are rotatably connected to the rotating shaft. A conveyor belt is sleeved on the outer surface of the two rotating shafts. By setting the conveyor belt, the carton can move automatically for folding and sealing, which improves the working efficiency of the device.

[0013] This utility model has the following beneficial effects:

[0014] This utility model, through the setting of a folding cover assembly, specifically involves turning on four motors to drive threaded rods to rotate on the inner wall of a fixed column, allowing a moving plate to move downwards. Activating an electric push rod causes a pressure rod to rotate on the outer surface of a rotating shaft, enabling the pressure bar to close the paper covers on both sides of the carton. As the moving plate moves downwards, the pressure plate flattens the paper covers, allowing the device to seal the carton. This eliminates the need for manual folding during carton sealing, reducing worker workload and improving the sealing efficiency of the device.

[0015] This utility model features a conveyor assembly. Specifically, two motors drive a rotating shaft to rotate, which in turn drives the shaft to rotate on the inner wall of the outer box via a belt. This allows the conveyor belt to rotate, placing the carton to be sealed on top of the rotating rod. The rotation of the conveyor belt causes the carton to move to the right on top of the rotating rod, enabling the carton to move automatically for folding and sealing. This eliminates the need for manual operation and reduces the workload of workers.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figure 1-5As shown, this utility model is a folding device for a carton sealing machine, including a base 1. Support legs 2 are fixedly connected to the four corners of the bottom of the base 1. Fixed posts 3 are fixedly connected to the front and back of the base 1. A folding assembly 22 is arranged above the base 1. The folding assembly 22 includes a motor 221. The bottom of the motor 221 is fixedly connected to the top of the fixed posts 3. A threaded rod 222 is fixedly connected to the bottom output end of the motor 221. The outer surface of the threaded rod 222 is rotatably connected to the inner wall of the fixed post 3. A moving rod 223 is threadedly connected to the outer surface of the threaded rod 222. By setting the folding assembly 22, manual folding is no longer required when sealing the carton, reducing the workload of workers and improving the sealing efficiency of the device. Specifically, by setting the folding assembly 22, the four corners of the carton are opened... Motor 221 drives threaded rod 222 to rotate on the inner wall of fixed column 3, allowing moving plate 224 to move downward. Electric push rod 233 activates pressure rod 231 to rotate on the outer surface of rotating shaft 230, causing pressure bar 235 to close the paper covers on both sides of the carton. As moving plate 224 moves downward, pressure plate 226 flattens the paper covers, allowing the device to seal the carton without manual folding, reducing worker workload and improving sealing efficiency. Moving plate 224 is fixedly connected to the end of moving rod 223 away from threaded rod 222. Pressure rod 225 (two in total) is fixedly connected to the bottom of moving plate 224, and pressure plate 226 is fixedly connected to the bottom of the two pressure rods 225. By setting up pressure rod 225, the top cover of the carton can be flattened, facilitating the sealing of the carton by the device. Four cylinders 227 are fixedly connected to the bottom of the moving plate 224. Support plates 228 are fixedly connected to the bottom of the four cylinders 227. Electric push rods 233 are fixedly connected to the top of the support plates 228. Telescopic rods 234 are fixedly connected to the front output end of the electric push rods 233. The support plates 228 allow the electric push rods 233 to operate more smoothly. A fixed block 232 is rotatably connected to the front of the telescopic rod 234. Pressure rod 231 is fixedly connected to the front of the fixed block 232. A rotating shaft 230 is fixedly connected to the back of the pressure rod 231. Fixed block 229 is rotatably connected to the outer surface of the rotating shaft 230. The back of panel 29 is fixedly connected to the front of the moving plate 224. By setting up pressure bar 231, the device can automatically fold the top cover of the carton, improving the device's working efficiency. A conveying assembly 11 is set above the base 1. The conveying assembly 11 includes a motor 111, the bottom of which is fixedly connected to the top of the base 1. A rotating shaft 112 is fixedly connected to the top output end of the motor 111. By setting up the conveying assembly 11, the carton can automatically move to fold and seal, eliminating the need for manual operation and reducing the workload of workers. Specifically, by setting up the conveying assembly 11, two motors 111 are turned on to drive the rotating shaft 112 to rotate. The belt 114 then drives the rotating shaft 117 to rotate on the inner wall of the outer carton 116, causing the conveyor belt 118 to rotate.The cartons to be sealed are placed on top of the rotating rod 4. The rotation of the conveyor belt 118 causes the cartons to move to the right on top of the rotating rod 4, allowing for automatic folding and sealing without manual operation, thus reducing worker workload. A pulley 113 is fixedly connected to the top of the rotating shaft 112, and a belt 114 is fitted onto the outer surface of the pulley 113. By using the belt 114, pulleys 113 and 115 can rotate simultaneously, reducing the energy consumption of the device. A second belt pulley 115 is located on the right side of belt pulley 113. The outer surface of belt pulley 115 is fitted onto the inner surface of belt 114. A rotating shaft 117 is fixedly connected to the bottom of belt pulley 115. Two outer boxes 116 are fixedly connected to the top of base 1. The inner walls of the two outer boxes 116 are rotatably connected to the rotating shaft 117. A conveyor belt 118 is fitted onto the outer surface of the two rotating shafts 117. By setting the conveyor belt 118, the cartons can move automatically for folding and sealing, improving the working efficiency of the device.

[0027] A specific application of this embodiment is as follows: First, turn on two motors 111 to drive the rotating shaft 112 to rotate. Simultaneously, the rotating shaft 112 will drive the belt pulley 113 to rotate. Belt pulley 113, through belt 114, will cause belt pulley 115 to rotate. The rotation of belt pulley 115 will drive the rotating shaft 117 to rotate on the inner wall of the outer box 116, causing the conveyor belt 118 to rotate. Place the carton to be sealed on the top of the rotating rod 4. The rotation of the conveyor belt 118 will allow the carton to move to the right from the top of the rotating rod 4. Then, turn on four motors 221 to drive the threaded rod. 222 rotates on the inner wall of the fixed column 3. While the threaded rod 222 rotates, it drives the moving rod 223 to move up and down, causing the moving plate 224 to move downward. The electric push rod 233 is activated to drive the telescopic rod 234 to retract, causing the pressure rod 231 to rotate on the outer surface of the rotating shaft 230. This allows the pressure strip 235 to close the paper covers on both sides of the carton. When the moving plate 224 moves downward, the pressure plate 226 can flatten the paper covers, enabling the device to seal the carton. This eliminates the need for manual folding when sealing the carton, reducing the workload of workers and improving the efficiency of the sealing process.
