Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery and equipment, in particular to a material pushing device suitable for a vacuum bagging machine. Background Art

[0002] Bagging machines are machines that use prefabricated packaging bags to package materials. They are completed by putting packaging bags on materials, or they are packaging machines that put materials into packaging bags. The operating principle of current bagging packaging machines is: the bag suction mechanism sucks the prefabricated bag out of the bag library, puts it on the bag support mechanism, and then the material is pushed into the packaging bag by the material pushing mechanism, flattens the bag mouth and vacuumizes it, and then continues to push it to the sealing mechanism for sealing. Some bagging machines are also equipped with a vacuum device to vacuum the packaged materials.

[0003] In the prior art, the pushing mechanism generally includes a pushing head and a pushing drive assembly that drives the pushing head to perform linear reciprocating motion. The vacuum device is generally provided separately, including a vacuum tube. When vacuuming, an additional mechanism is required to push the packaging bag into the working area of ​​the vacuum tube, or to move the vacuum tube into the packaging bag. In this process, the position of the vacuum tube and the packaging bag needs to be repositioned. Therefore, the vacuum bagging machine in the prior art has a complex structure and a poor positioning effect. Summary of the invention

[0004] In order to solve the above technical problems, the utility model proposes a material pushing device suitable for a vacuum bagging machine, which does not require an additional re-positioning mechanism during vacuuming, and can effectively solve the problems of complex structure and poor positioning effect of existing vacuum bagging machines.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] A material pushing device suitable for a vacuum bagging machine includes a material pushing head, a vacuum tube, a driving assembly, and a material pushing driving device for driving the material pushing head to and fro. The vacuum tube is connected to the driving assembly and, driven by the driving assembly, extends outward from the outer end surface of the material pushing head or retracts inward to the inner side of the outer end surface.

[0007] A first accommodating cavity is provided in the pushing head, and a through hole communicating with the first accommodating cavity is provided on the outer end surface of the pushing head. The driving component drives the vacuum tube to pass through the through hole and then extend out of the outer end surface of the pushing head or retract inward into the first accommodating cavity.

[0008] A limiting device for limiting the moving direction of the vacuum tube is also provided in the first accommodating chamber.

[0009] The driving assembly includes a mounting frame, a driving motor, a rack and a gear meshing with the rack; the driving motor is mounted on the mounting frame, the gear is mounted on the output shaft of the driving motor, and the rack is connected to the vacuum tube.

[0010] The pusher drive device comprises a pusher rod and a pusher drive assembly. The pusher rod is fixedly connected to the pusher head and the pusher drive assembly respectively. The pusher drive assembly drives the pusher rod to move back and forth. The drive assembly is arranged on the pusher rod.

[0011] The push drive device includes a push rod, a push slide, a slide rail and a push drive assembly. The push rod is fixedly connected to the push slide and the push head respectively. The push drive assembly drives the push slide to reciprocate along the slide rail. The drive assembly is arranged on the push slide.

[0012] The rack is slidably connected with the material pushing slide.

[0013] The push rod is slidably connected with the vacuum pumping tube.

[0014] A second accommodating cavity is provided in the push rod for accommodating a vacuum tube.

[0015] The surface of the push rod is also provided with a limiting groove communicated with the second accommodating chamber, the rack is connected to the vacuum tube via a limiting block, and the limiting block matches the limiting groove.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. In the utility model, after the pushing head pushes the material into the packaging bag, the pushing head withdraws from the packaging bag, and at the same time, the driving component drives the vacuum tube to extend outward from the outer end surface of the pushing head, so that the vacuum tube stays in the packaging bag. At this time, the packaging bag is formed by the other components of the vacuum bagging machine, such as the bag clamping device, to tighten the bag mouth to perform negative pressure vacuuming. After completing the action, the vacuum tube retracts to its original state position.

[0018] In this process, since the pushing head has completed the positioning work when pushing the material, the relative position relationship between the pushing head and the packaging bag has been determined. When the vacuum tube is working, it extends out of the outer end surface of the pushing head, so there is no need to position it again, which eliminates the transportation and repeated positioning mechanism during vacuuming, and the structure is simpler. Moreover, the overall working efficiency of the vacuum bagging machine is also improved.

[0019] 2. A through hole is set on the outer end surface to further limit and locate the position of the vacuum tube, thereby improving the position accuracy of the vacuum tube when it is working. When vacuuming is not needed, the vacuum tube will retract into the first accommodating cavity, which has a better dustproof effect, a shorter travel distance of the vacuum tube, and a more stable movement of the vacuum tube.

[0020] 3. A limiting device for limiting the moving direction of the vacuum tube is also provided in the first accommodating chamber, which can further limit the position of the vacuum tube and ensure the stability of the vacuum tube during reciprocating motion.

[0021] 4. The driving assembly is arranged on the push rod, so that the driving assembly and the vacuum tube can reciprocate together with the push rod, reducing the travel distance of the vacuum tube driven by the driving assembly to reciprocate, and the structure is more stable.

[0022] 5. The driving assembly is arranged on the push slide, so as to better arrange the positions of the driving assembly and the vacuum tube.

[0023] 6. The rack is slidably connected to the push slide, which is convenient for improving the stability of the reciprocating movement of the rack.

[0024] 7. The push rod is slidably connected to the vacuum tube, so as to further improve the stability of the reciprocating movement of the vacuum tube.

[0025] 8. A second accommodating chamber is provided inside the push rod for placing a vacuum tube, so as to better arrange the positions of various components.

[0026] 9. The cooperation between the limit groove and the limit block can better limit the maximum distance of the rack movement and play a good limiting role. BRIEF DESCRIPTION OF THE DRAWINGS
