Among them, the other end of the belt drive shaft 5 is mounted on the second fixed plate 45, and the drive belt pulley 6, the driven belt pulley 7, the entrance belt supporting plate 8, the entrance conveying belt 9 and the blocking cylinder 10 are respectively mounted on the first moving plate 24 and the second moving plate 25. The entrance conveying assembly is responsible for the product input function in the device, and can be connected with the front end flow line to form an unmanned automation. When the sleeve sealing machine fails, the blocking cylinder 10 extends, and the blocking block 11 mounted on the head thereof blocks the product from continuing to flow into the device, preventing the product from piling up and causing greater failure and damaging the product.

[0053] In this embodiment, the entrance conveying assembly is mounted on the first moving plate 24 and the second moving plate 25, and for different width products entering the device, only the width adjusting hand wheel needs to be twisted to adjust the first moving plate 24 and the second moving plate 25, so as to adapt to different width products and realize rapid adjustment.

[0054] As shown in the figure, Figure 4 The secondary positioning and sorting conveyor assembly B is connected with the entrance conveying assembly, the arrangement motor 12 mounted on the arrangement motor plate 20 drives the arrangement drive shaft 15, the arrangement drive belt pulley 13 is mounted on the arrangement drive shaft 15, the arrangement drive belt pulley 13 drives the arrangement driven belt pulley 14 mounted on the arrangement driven shaft 16 through the arrangement belt 17, and the conveying structure is formed; the arrangement motor plate 20 is connected with the arrangement mounting plate 21 through the arrangement connecting plate 22, the arrangement belt supporting plate 23 is mounted on the arrangement connecting plate 22 and closely adheres to the arrangement belt 17 to prevent the belt from deviating and tightly adhering to the product; the arrangement tensioning wheel 18 is mounted on the arrangement tensioning shaft 19, and the arrangement tensioning shaft 19 is respectively mounted on the arrangement motor plate 20 and the arrangement mounting plate 21 to adjust the tension of the arrangement belt 17.

[0055] The secondary positioning and sorting conveyor assembly B has two, which are respectively mounted on the first moving plate 24 and the second moving plate 25, and for different width products entering the device, only the width adjusting hand wheel needs to be twisted to adjust the first moving plate 24 and the second moving plate 25, so as to adapt to different width products and realize rapid adjustment.

[0056] As shown in the figure, Figure 5As shown, the main structural component of the sleeve sealing device assembly C is: the sleeve sealing plate 43 is mounted on the first fixed plate 44 and the second fixed plate 45 respectively through the first middle plate support shaft 46 and the second middle plate support shaft 47 fixed thereon, forming support and fixation. See Figure 5 The final moving parts, the sleeve chain 31 and the circular belt 37, installed on the sleeve plate 43, work in conjunction with the sleeve drive motor 26 and the motor synchronous pulley 38 installed thereon to drive the "chain drive synchronous pulley 39 corresponding to the sleeve chain 31" and the "circular belt drive synchronous pulley 40 corresponding to the circular belt 37". This drives the corresponding sleeve drive shaft 27 and circular belt drive shaft 34, which in turn drive the sleeve drive sprocket 28 and circular belt drive wheel 33 installed thereon. The sleeve drive sprocket 28 drives the sleeve driven sprocket 29 through the sleeve chain 31 to form a running mechanism. The circular belt drive wheel 33 drives the first circular belt pulley 35 and the second circular belt pulley 36 through the circular belt 37 to form a running mechanism. The ultimate purpose of this component structure combination is to make the linear speed of the sleeve chain 31 and the circular belt 37 consistent, so that there will be no relative displacement when the product moves, and the product and the sleeve are in a set relative position and are transported together to the output conveyor assembly H. The second synchronous belt tensioner 42 is used to increase the wrap angle of the transmission synchronous belt with the motor synchronous pulley 38, while the first synchronous belt tensioner 41 is used to tension the transmission synchronous belt. The push plate 32 is mounted on the sleeve chain 31 and is used to push the product into the sleeve.

[0069] The working principle process and action steps of the equipment are as follows:

[0070] The sleeve machine is an automatic equipment for automatically sleeving the sleeve into the product. The operator pulls the sleeve pressing block 48G in the sleeve storage device assembly D, puts the pre-folded sleeve, and then drops the sleeve pressing block 48G, so that the lower end of the sleeve is tightly attached to the lower limiting front clamping block 48E, and the upper end is tightly attached to the upper limiting upper clamping block 49H. The equipment is started, the longitudinal module 53A in the upper suction sleeve assembly E moves to the suction plate assembly 57, tightly attaches to the lower limiting front clamping block 48E and the upper limiting upper clamping block 49H of the sleeve storage device assembly D, adsorbs the sleeve, reversely moves to separate the sleeve from the sleeve storage device assembly D, and continuously moves to the pre-set relative position above the sleeve device assembly C. The suction plate assembly 56 rotates to make the sleeve horizontal below and wait.

[0071] After the products flow into the equipment by the inlet conveying assembly combined with the blocking device A, the products enter the secondary positioning and aligning conveyor assembly B after avoiding the push plate 32 of the sleeve device assembly C moving in the middle of the secondary positioning and aligning conveyor assembly B at the corresponding time, the products are repositioned in the secondary positioning and aligning conveyor assembly B, and are stopped at the end of the conveying direction of the secondary positioning and aligning conveyor assembly B. It can be seen that the inlet conveying assembly combined with the blocking device A has the functions of receiving the products flowing into the equipment and timed feeding, preventing the push plate 32 from damaging the products and the equipment.

[0072] After the product reaches the end, the lower suction sleeve assembly F moves up until the suction disc group 62 is close to the lower end of the sleeve, then the suction disc group 62 moves down to adsorb the sleeve, the suction disc assembly 57 of the upper suction sleeve assembly E adsorbs the upper end of the sleeve until it is completely separated from the lower suction sleeve assembly F, then the suction disc assembly 57 is disconnected from the vacuum to release the upper end of the sleeve; the lower suction sleeve assembly F adsorbs the sleeve to the lower end of the sleeve and keeps adsorbing, the auxiliary forming part 67 helps the sleeve to form a shape suitable for the product, and the cylinder head opening part 66 of the opening cylinder 64 drives the product to flow into the sleeve edge of the sleeve; when the push plate 32 moves to contact the product, the secondary positioning and alignment conveyor assembly B is started again, and the product is moved in the outlet direction synchronously with the push plate 32, passes through the flow guide part 63A and the cylinder head opening part 66, and enters the sleeve; when the product enters the sleeve to the required packaging position (i.e. the sleeve is in the front, middle, end, etc. of the product), the suction disc group 62 of the lower suction sleeve assembly F is disconnected from the vacuum to release the adsorption of the sleeve, and is lowered again until the suction disc group is completely separated from the end of the sleeve, so that the movement of the sleeve does not rub the suction disc and stops waiting for the next product to flow into the secondary positioning and alignment conveyor assembly B in the end of the conveying direction, and then the action cycle is started again.

[0073] The push plate 32 of the sleeve sleeve device assembly C is synchronized with the circular belt 37 to convey the product to the output conveyor assembly H under the assistance of the auxiliary forming part 67; the output conveyor assembly H continues to convey the product out of the sleeve machine under the assistance of the auxiliary forming part 67.
