Description

Technical Field

[0001] The utility model belongs to the technical field of foaming equipment, and in particular relates to a paper feeding mechanism for a push-in filling foaming machine. Background Art

[0002] During the implementation of the polyurethane pouring process, a filling foaming machine is used to transport the polyurethane mixture to a dedicated pouring gun nozzle for foaming. However, different methods are used for pouring objects of different shapes and structures, especially for the straight hole filling process. At present, there are two main straight hole filling technologies: direct pouring and push-in pouring. The push-in process involves bending the paper tape in advance, and then injecting the prepared polyurethane raw material onto the paper tape. The paper tape is used to guide and push the raw material into the straight hole to form polyurethane foam in the hole. This method not only ensures a high filling efficiency, but also produces high-quality foaming effects in the hole.

[0003] However, the existing push-in polyurethane filling and foaming equipment on the market has certain design flaws. When the equipment continuously fills straight holes at high speed, after completing the filling task of a hole and stopping feeding, the paper tape will often continue to be fed out due to the rotational inertia of the paper tape roll itself, causing the paper tape to accumulate and coil inside the equipment. When working again, the paper tape will get stuck in the equipment, affecting the subsequent smooth operation of the equipment. In addition, considering different application scenarios, the required paper tape widths vary. After replacing paper tapes of different widths, existing models may experience paper tape bending, offset and inaccurate positioning, which may cause equipment malfunction.

[0004] Therefore, it is necessary to study a paper feeding mechanism for a push-in filling foaming machine that can prevent the paper tape from getting stuck in the device and can be suitable for paper tapes of different sizes. Utility Model Content

[0036] The paper feed assembly 1 is fixedly mounted on the frame 7, and the paper roll is mounted on the paper feed assembly 1. Specifically, the paper feed assembly 1 comprises: a paper feed assembly bracket 11, a first paper roll clamping disc 12, a second paper roll clamping disc 13, and a fixing member 14.

It can be understood that the paper tape roll is mounted on the fixing shaft 111, and the second paper roll clamping disc 13 and the paper tape roll are fixed by the fixing member 14. Specifically, the paper feed assembly bracket 11 also includes a paper storage box 15, and the paper storage box 15 is fixedly mounted on the frame 7.

A rotating shaft 151 is arranged inside the paper storage box 15. It can be understood that after the paper tape is fed out from the paper tape roll, it bypasses the rotating shaft 151 and enters the positioning assembly 2. After completing the filling task of one hole and stopping the feeding, the paper tape continues to be fed out under the action of the rotational inertia of the paper tape roll itself. At this time, the fed paper tape will enter the paper storage box 15, and the paper tape in the paper storage box 15 cannot be stacked or coiled, which can effectively prevent the paper tape from getting stuck in the device when it is started again.

The upper folding roller 32 is rotatably mounted on the folding assembly bracket 31, and the lower folding roller 33 is rotatably mounted on the frame 7. The upper folding roller 32 cooperates with the lower folding roller 33 to press out an indentation on the paper tape. Specifically, the upper folding roller 32 is provided with an annular protrusion, and the lower folding roller 33 is provided with an annular groove that cooperates with the annular protrusion provided on the upper folding roller 32. It can be understood that the paper tape passes between the upper folding roller 32 and the lower folding roller 33, and the annular protrusion on the upper folding roller 32 cooperates with the annular groove on the lower folding roller 33 to press out a crease on the paper tape.

[0039] The bending assembly 4 is fixedly mounted on the frame 7, and the bending assembly 4 drives the paper tape to pass through the positioning assembly 2 and the folding assembly 3, and bends the paper tape after the folding assembly 3 presses out the folds and exits the paper slot.

The slider 41 is slidably mounted on the frame 7, one end of the screw rod 42 is fixedly connected to the hand wheel 43, and the other end passes through the frame 7 and is hinged to the slider 41. The screw rod 42 and the frame 7 are threadedly matched, the bending roller 44 is rotatably mounted on the slider 41, the traction wheel 45 is rotatably mounted on the frame 7, and the traction wheel 45 is connected to the driving assembly 5. Specifically, the bending roller 44 is provided with an annular protrusion, and the traction wheel 45 is provided with an annular groove that cooperates with the annular protrusion provided on the bending roller 44. It can be understood that the paper tape passes between the bending roller 44 and the traction wheel 45, and the driving component 5 drives the traction wheel 45 to rotate, thereby migrating the paper tape from the paper tape roll and passing through the positioning component 2, the folding component 3, and the bending component 4 to enter the paper output component 6. When the paper tape passes through the bending roller 44 and the traction wheel 45, the annular protrusion on the bending roller 44 cooperates with the annular groove on the traction wheel 45 to bend the paper tape along the indentation.

[0040] The driving assembly 5 is connected to the bending assembly 4 .

[0041] The paper discharging assembly 6 is fixedly mounted on the end surface of the bending assembly 4 away from the folding assembly 3 .
