[0023] Reference Figures 1 to 6An online can sealing module of the present invention comprises a can conveying mechanism 1 for feeding and discharging cans, a can pressing mechanism 2 arranged at the end of the can conveying mechanism 1 and used to fix the position of the can, and a gluing mechanism 3 arranged on either side of the can pressing mechanism 2; the can conveying mechanism 1 comprises a guide rail 14, a clamping mechanism slidably connected to the guide rail 14 and clamping the can from both sides of the can, the clamping mechanism is provided with a plurality of through holes 12 matching the shape of the can, the clamping mechanism is provided with a groove 13 for pushing out the can on the can pressing mechanism 2 on one side close to the can pressing mechanism 2, the clamping mechanism slides on the guide rail 14 and delivers the can into the can pressing mechanism 2.

[0024] During operation, after the biscuits are assembled in the can, they are transported from the assembly line to the can conveying mechanism 1, which is arranged on the assembly line. After the can is positioned by the through hole 12 in the clamping mechanism, it is sent to the can pressing mechanism 2 for pressing, and the can is sealed by the gluing mechanism 3. After the gluing is completed, refer to Figure 5 While the clamping mechanism is feeding the next group of cans, the can pressing mechanism 2 releases the cans, and the cans in the can pressing mechanism 2 are pushed out and recovered through the groove 13. The cans are positioned and transported in and out through the pipe mechanism, so that the can sealing process can be immediately followed by the canning process, thereby achieving the purpose of completing all processes on the same production line and greatly improving work efficiency.

[0025] In one embodiment, the clamping mechanism includes two clamping plates 11 respectively arranged on both sides of the can, and the clamping plates 11 are driven by a cylinder to move closer and clamp the can, and the can is accommodated in the through hole 12. The can conveying mechanism 1 also includes a pre-positioning mechanism arranged directly above the initial position of the clamping mechanism, and the pre-positioning mechanism includes a plurality of baffles 15 that can move up and down above the clamping mechanism, and the baffles 15 are arranged above the through hole 12.

[0026] When the can is input between the two clamps 11, the baffle 15 drops to prevent the can from moving forward. The clamps 11 clamp the can in the through hole 12 under the action of the cylinder, thereby performing the final positioning and then transporting it to the can pressing mechanism 2 for the next step.

[0027] Preferably, as a further improvement of the above embodiment, the can pressing mechanism 2 includes a plurality of turntables 21 for holding cans, and a pressing block 22 for pressing the cans from above, and the distance between the centers of two adjacent turntables 21 is equal to the distance between the centers of two adjacent through holes 12.

[0028] When the cans enter the can pressing mechanism 2 driven by the clamping mechanism, several cans can accurately enter the center position of the turntable 21 under the constraint of the through hole 12, effectively preventing the position of the cans entering the turntable 21 from being offset and causing the cans fixed after the pressing block 22 is pressed down to be eccentric.

[0029] Reference Figure 6 As an optimization and improvement of this embodiment, in order to avoid damage to the surface of the can due to excessive pressure during the downward pressing process, the pressing block 22 includes a rotating block 222 rotatably connected to the push rod of the cylinder, and an abutting block 221 abutting against the surface of the can, the abutting block 221 and the pressing block 222 are fixedly connected by screws, and a third buffer spring 223 is arranged between the abutting block 221 and the pressing block 222.

[0030] Preferably, in this embodiment, the glue sticking mechanism 3 includes a frame 31, a plurality of conveying wheels fixed on the frame 31 for winding the tape, a glue pressing mechanism rotatably connected to the frame 31 and pressing the tape, and a cutter 36 rotatably connected to the frame 31 and cutting the tape, the conveying wheel includes a fixed roller 32 for winding the tape, a first swing arm 38 rotatably connected to the frame 31, and a glue feeding wheel 33 installed at the end of the first swing arm 38 and used to stick the end of the tape to the edge of the can, the frame 31 is also rotatably connected to a baffle 34 for cooperating with the glue feeding wheel 33 to fix the end of the tape, and the end of the tape is fixed between the edges of the glue feeding wheel 33 and the baffle 34. The glue pressing mechanism includes a second swing arm 37 rotatably connected to the frame 31, and a pressing wheel 35 installed at one end of the second swing arm 37 close to the can.

[0031] After the can enters the turntable 21, the pressing block 22 presses down and compacts the can. Preferably, the pressing block 22 is pressed down to the surface of the can by the cylinder. The pressing block 22 is rotatably connected to the end of the ejection rod of the cylinder. Furthermore, the baffle 34 is away from the glue feeding wheel 33, and the glue feeding wheel 33 sticks the end of the tape to the surface of the can. Then, the turntable 21, driven by the motor, cooperates with the pressing block 22 to drive the can to rotate. The pressing block 22 rotates freely with the can, and the pressing wheel 35 presses against the edge of the can to make the tape fit better. Finally, the cutter 36 is used to cut the tape to complete the can sealing work.

[0032] Preferably, when the rubber feeding wheel 33 is pressed against the surface of the can, there is a possibility that the surface of the can will be damaged due to excessive pressure. In order to avoid damage, a second buffer spring 381 is provided between the first swing arm 38 and the frame 31.

[0033] During the continuous operation, when the can rotates driven by the turntable 21 and completes the sealing, the clamp 11 clamps the new can into the turntable 21. If the turntable 21 is still rotating, the can that has just entered the turntable 21 will rotate accordingly. However, at this time, the pressing block 22 does not press the can tightly, which may cause serious deviation of the can at best, or even cause the can to fly out of the turntable 21 at worst. Therefore, as a preferred embodiment, the lower part of the turntable 21 is provided with an electromagnetic brake 23 for stopping the rotation of the turntable 21. After the can completes the sealing process, the electromagnetic brake 23 is used to stop the rotation of the turntable 21. At this time, the can to be sealed is brought onto the turntable 21 through the clamp 11, and the sealed can is pushed out and recovered.

[0034] Reference Figure 1 and Figure 2 The glue sticking mechanism 3 also includes a storage roller 39 which is rotatably connected to the frame 31 and is used to prevent the tape from falling. The tape is placed in the storage roller 39 and winds around several fixed rollers 32 in turn, and finally reaches the glue feeding wheel 33, and the baffle 34 is rotated to make the end of the baffle close to the glue feeding wheel 33, thereby effectively preventing the tape from falling.

[0035] Preferably, in an improvement of the present embodiment, a buffer mechanism is provided between the second swing arm 37 and the frame 31 , and the buffer mechanism comprises a first buffer spring 371 with one end fixed to the frame 31 and the other end fixed to the second swing arm 37 .

[0036] During the can sealing process, the can is prone to slight deviation, and the slight deviation will cause the second swing arm 37 to move backward, and the distance between the edge of the can that deviates toward the center and the pressure wheel 35 is twice the amount of the second swing arm 37 moving backward, resulting in a failure to press tightly. The first buffer spring 371 is provided, and the second swing arm 37 can be kept in its original position under the action of the first buffer spring 371, which can reduce the deviation and utilize the elastic force of the first buffer spring 371 to restore the can to its original position, effectively ensuring that the pressure wheel 35 can make the tape fit perfectly on the sealing portion of the can. Because the first buffer spring 371 is provided, the quality of can sealing can be continuously guaranteed, providing quality assurance for online can sealing.

[0037] Preferably, the gluing mechanism 3 is also connected to a moving device for changing the position of the gluing mechanism 3 , and the moving device includes a first moving pair for controlling the lateral movement of the frame 31 , and a second moving pair for controlling the vertical movement of the frame 31 .

[0038] Preferably, the first kinematic pair and the second kinematic pair are both screw pairs, which can ensure the reliability of movement and ensure that the position remains unchanged after movement.

[0039] By changing the position of the gluing mechanism 3, the distance between the gluing mechanism 3 and the center of the turntable 21 is changed, so that different sizes of cans can be adapted, thereby improving the practicality of the entire can sealing module.

[0040] The above specific structures and dimensional data are specific descriptions of the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent deformations or substitutions without violating the spirit of the present invention. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
