[0029] Please refer to Figures 1 to 5 The utility model proposes a pushing mechanism for a stacking automatic feeder for tubular packaged materials. The stacking automatic feeder for tubular packaged materials comprises a frame 1 and a silo 2 arranged on the frame 1. The silo 2 is used for stacking material tubes, in which materials are packaged.

[0030] The preferred embodiment of the push mechanism of the utility model for the stacking automatic feeder of tubular packaging materials includes a strip push rod 3, a rubber-coated wheel 4, a rubber-coated bearing assembly, a drive motor (not shown in the figure) and a reduction gear pair. The output shaft of the drive motor is connected to the rubber-coated wheel 4 through the reduction gear pair. The push rod 3 is wound around the rubber-coated wheel 4, and one end extends into the material tube. The rubber-coated bearing assembly presses the push rod 3 onto the rubber-coated wheel 4.

[0031] In this embodiment, the rubber-coated bearing assembly includes at least one rubber-coated bearing 5. The rubber-coated bearing 5 and the rubber-coated wheel 4 rub against each other to rotate the push rod 3, generating a relative thrust during the rotation process.

[0032] In this embodiment, the push rod 3 extends into the material pipe. When the driving motor drives the rubber-coated wheel 4 to rotate through the reduction gear pair, the push rod 3 moves forward under the friction between the rubber-coated wheel 4 and the rubber-coated bearing assembly, pushing the material in the material pipe to move forward.

[0033] The driving motor can be a stepper motor, which drives the rubber bearing assembly to rotate through the reduction gear pair transmission structure, driving the push rod 3 to enter the material tube to push the material, and can achieve stable feeding according to the preset speed, length, etc. The push rod 3 can be mechanically adjusted forward and backward according to the actual length of the material tube.

[0034] Compared with the prior art that adopts the air-blowing feeding solution, this embodiment adopts the push rod 3 to push the material in the material tube to move forward. The force and stroke can be controlled by parameter setting. The material movement is stable and reliable, which can effectively avoid problems such as material jamming and flipping, thereby improving production efficiency.

[0035] In this embodiment, rubber-coated wheel baffles 6 are provided on both sides of the rubber-coated wheel 4 to escort the push rod 3. In this embodiment, the rubber-coated wheel baffles 6 can limit and correct the push rod 3, thereby preventing the push rod 3 from deviating, thereby further improving the stability and reliability of material movement.

[0036] In this embodiment, a material push in place sensor 7 is provided on the frame 1 at the front end of the material pipe, and the material push in place sensor 7 is connected to the control signal of the drive motor, and the material push in place sensor 7 cooperates with the drive motor to control the movement of the push rod 3. For example, when the material push in place sensor 7 senses that there is no material at the front end of the material pipe, the drive motor is controlled to work, and the material is pushed forward through the push rod 3. When the material push in place sensor 7 senses that there is material at the front end of the material pipe, the drive motor is controlled to stop working, and the push rod 3 temporarily pushes the material forward.

[0037] Furthermore, in this embodiment, a push rod sensor 8 is provided on the frame 1 near the rubber-coated wheel 4, and the push rod sensor 8 serves as the relative position origin of the driving motor.

[0038] In this embodiment, a clearance hole 9 is provided at one end of the push rod 3 , and the clearance hole 9 serves as a sensing part of the push rod sensor 8 .

[0039] In this embodiment, the push rod 3 is made of a highly elastic metal material.

[0040] In specific implementation, the push rod 3 can be designed to be thickened to ensure that the material in the material tube is pushed and to prevent deformation of the push rod 3 during pushing. In addition, the thickened design can be applied to the thinnest tube-filled material and relatively large-sized materials.

[0041] Furthermore, in this embodiment, the material pushing mechanism also includes an automatic material pipe replacement mechanism arranged at the material bin 2.

[0042] Specifically, the automatic material tube replacement mechanism includes two groups of tube changing units 10 arranged on the frame 1 along the front-to-back direction, and the tube changing unit 10 includes a slide rail, a slider 11, a tube pushing part 12 and a cylinder 13. The slide rail is transversely arranged on the frame 1, and the slider 11 is slidably arranged on the slide rail. The tube pushing part 12 is connected to the slider 11, and the cylinder 13 is connected to the tube pushing part 12. The cylinder 13 is used to drive the tube pushing part 12 to move transversely.

[0043] The frame 1 is also provided with a material pipe sensor 14 and a controller connected to the material pipe sensor 14 . The material pipe sensor 14 is used to sense the material pipe in the silo 2 .

[0044] During operation, the two groups of the tube changing units 10 move synchronously to ensure that the empty tubes are pushed smoothly without being stuck. When the tube sensor 14 senses that there is no material in the tube, the drive motor is controlled to retract the push rod 3, and then the cylinder 13 is controlled to push the tube pusher part 12 outward to push the empty tube out. In this embodiment, when the tube sensor 14 senses that there are less than two tubes in the silo 2, the controller prompts the user to add a tube.

[0045] It is worth mentioning that in this embodiment, a plurality of material pipes can be stacked in the silo 2. When the lower material pipe is pushed out, the upper material pipe falls to the bottom of the silo 2 under the action of gravity, and then the driving motor controls the movement of the push rod 3 to extend the push rod 3 into the material pipe.

[0046] As an implementation scheme, in this embodiment, a forward material pipe pushing cylinder 15 is provided at the rear end of the silo 2 below the frame 1, and a forward material pipe pushing in-place sensor 16 is provided at the front end of the silo 2 below the frame 1. The forward material pipe pushing cylinder 15 is used to push the material pipe that has fallen to the bottom of the silo 2 forward to the transfer mechanism when automatically changing the material pipe, and the forward material pipe pushing in-place sensor 16 is used to detect the material pipe pushed by the forward material pipe pushing cylinder 15.

[0047] In this embodiment, the material tube sensor 14 cooperates with the automatic material tube replacement mechanism to automatically discharge the empty tube after the material in the tube is delivered, and then automatically replace the new tube and fix it in place.

[0048] Furthermore, in the present embodiment, the silo 2 comprises a material pipe slot vertically arranged on the frame 1 along the front-to-back direction, and a bevel is arranged at the bottom of the material pipe slot.

[0049] In this embodiment, an oblique angle is provided at the bottom of the material tube slot, so as to guide the material tube and facilitate the discharge of the material tube.

[0051] The utility model adopts the above technical scheme, includes a strip push rod, a rubber-coated wheel, a rubber-coated bearing assembly and a driving motor, the output shaft of the driving motor is connected to the rubber-coated wheel, the push rod is wound around the rubber-coated wheel, and one end extends into the material pipe, the rubber-coated bearing assembly presses the push rod onto the rubber-coated wheel, and the push rod is used to push the material in the material pipe to move forward, the force and stroke can be controlled by parameter setting, the material movement is stable and reliable, and the problems of material jamming and flipping can be effectively avoided, thereby improving the production efficiency.
