The pressing wheel rotates in the opposite direction to the conveyor belt, and correspondingly, the pressing wheel and the conveyor belt cooperate to squeeze the loose material packaging products.

[0005] A driving gear is arranged at the other end of the driving shaft, a driven gear meshing with it is arranged on the corresponding mounting plate, a driving sprocket coaxial with the driven gear is arranged on the driven gear, and a driven sprocket is arranged at one end of the rotating shaft of the pressing wheel. A chain is connected between the driven sprocket and the driving sprocket for transmission.

[0006] Both ends of the rotating shaft of the pressing wheel are rotatably arranged on sliding blocks respectively. The sliding blocks can move up and down between the vertical beams of the gantry. An adjusting screw is axially movably penetrated through the cross beam of the gantry. An adjusting handwheel is arranged at the upper end of the adjusting screw, and the lower end of the adjusting screw is threadedly connected to the sliding block. A spring is sleeved on the adjusting screw, and upper and lower spring seats are arranged at both ends of the spring respectively. The upper spring seat abuts against the lower end of the cross beam of the gantry, and the lower spring seat abuts against the upper end of the sliding block.

[0007] The beneficial effect of the utility model is that for the improved conveying and flattening device of the packaging machine, by arranging a pressing wheel above the conveyor belt, and the height of the pressing wheel is adjustable, and the pressing wheel has an elastic pressing force. By adjusting the pressing wheel, the loose material packaging products passing through can be made flat, which is convenient for boxing and improves aesthetics. Brief Description of the Drawings

[0012] The accompanying drawings show the structure of the utility model, and the following further describes its relevant details in conjunction with the accompanying drawings. Figures 1-3 The conveying and flattening device of the packaging machine includes a conveyor belt 1 and a driving shaft 2. The driving shaft 2 is rotatably arranged on mounting plates 3 on both sides. A rotating power source 4 is provided at one end of the driving shaft 2. The rotating power source 4 is preferably a motor. A support plate 5 is provided inside the conveyor belt 1. A height-adjustable pressing wheel 6 is provided above the conveyor belt 1. The pressing wheel 6 has an elastic pressing force. The pressing wheel 6 is preferably located above the end of the conveyor belt 1. The pressing wheel 6 rotates in the opposite direction to the conveyor belt 1. The corresponding pressing wheel 6 and the conveyor belt 1 cooperate with each other to squeeze the loose materials to package the product.

[0013] The working principle of the utility model is to pre-adjust the height of the pressing wheel 6, and then the loose material packaging product is conveyed to the bottom of the pressing wheel 6 via the conveyor belt 1. Under the action of the pressing wheel 6, the conveyor belt 1 and the support plate 5, the loose material packaging product is elastically squeezed to flatten the uneven shape.

[0014] As a specific implementation of further improvement, a driving gear 7 is provided at the other end of the driving shaft 2, and a driven gear 8 meshing therewith is provided on the corresponding mounting plate 3, and the driven gear 8 is provided with a driving sprocket 9 coaxially linked therewith, and a driven sprocket 10 is provided at one end of the rotating shaft of the pressure wheel 6, and a chain 11 is connected between the driven sprocket 10 and the driving sprocket 9 to realize the transmission of the pressure wheel 6, and the rotation direction is opposite to that of the conveyor belt 1.

[0015] As a specific implementation of a further improvement, both ends of the rotating shaft of the pressing wheel 6 are rotatably arranged on the sliding blocks 12 respectively. The sliding blocks 12 are arranged between the vertical beams of the gantry 13 in a vertically movable manner. An adjusting screw rod 14 is axially movably inserted through the cross beam of the gantry 13. An adjusting handwheel 15 is provided at the upper end of the adjusting screw rod 14. The lower end of the adjusting screw rod 14 is threadedly connected to the sliding block 12. A spring 16 is sleeved on the adjusting screw rod 14. Upper and lower spring seats 17 and 18 are respectively arranged at both ends of the spring 16. The upper spring seat 17 abuts against the lower end of the cross beam of the gantry 13, and the lower spring seat 18 abuts against the upper end of the sliding block 12. During operation, by rotating the adjusting handwheel 15, the adjusting screw rod 14 is driven to rotate. Correspondingly, the lower end of the adjusting screw rod 14 drives the sliding seat to lift through the thread. Correspondingly, the spring 16 contracts or elongates. When the pressing wheel 6 presses the material, the sliding block 12 and the adjusting screw rod 14 lift together, and are elastically pressed by the spring 16, so that it can be ensured that the seal of the material packaging bag is not damaged during the extrusion process, and the appearance is more flat.

[0016] In summary, the above are only the preferred embodiments of the present invention, and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
