Description

Technical Field

[0001] The present application relates to the field of automatic feeders, and in particular to a feeding device for a preforming machine. Background Art

[0002] Preforming is to place a mixture of PTFE and lubricating oil in a tubular device and pre-press it into a cylindrical blank under a certain pressure. This is to remove the air between the resin particles after adding the lubricating oil, so that the resin particles are tightly combined, and finally obtain a mechanically acceptable preformed product for paste extrusion. In the preforming process of the product, a preforming machine is required. By adding materials to the preforming machine, a cavity is set in the preforming machine, and the materials are preformed in the cavity by pressurizing the materials. The processed product is then taken out of the preforming machine and subjected to subsequent paste extrusion.

[0003] When the preformer is working, the raw materials are in a loose state. When the raw materials are small, they can be directly fed into the cavity. When the raw materials are large, the cavity space of the preformer is insufficient. At this time, it is necessary to add a feeding cylinder above the cavity entrance, and then feed the materials into the cavity through the feeding cylinder. Therefore, for different amounts of materials, there will be two feeding heights, namely the height of the cavity itself and the height after adding the feeding cylinder.

[0004] In order to reduce the labor intensity of the feeding process and reduce the contamination of material contact with hands, automatic feeders are generally used. However, the common automatic feeders can only adapt to one feeding height, so there is still the problem of difficulty in feeding that needs to be solved. Utility Model Content

[0039] This embodiment discloses a preformer feeding device, referring to Figure 1 and Figure 2 The preforming machine feeding device includes a first support frame 1, a second support frame 2, a lifting mechanism 4 and a conveying mechanism 3. The second support frame 2 is located at the end of the first support frame 1 and is rotatably connected to the first support frame 1, so that the second support frame 2 can rotate relative to the first support frame 1, thereby changing its angle and position relative to the first support frame 1. The lifting mechanism 4 is arranged on the first support frame 1, and its output end is connected to the second support frame 2, which is used to drive the second support frame 2 to rotate, thereby adjusting the height of the second support frame 2. The conveying mechanism 3 includes a first segment arranged on the first support frame 1 and a second segment arranged on the second support frame 2, and a loading frame 36 for carrying materials, and the automatic loading of materials is realized through the conveying mechanism 3.

[0040] Reference Figure 3 and Figure 4 According to the actual feeding height requirement, the angle and position of the second support frame 2 are adjusted by the lifting mechanism 4, thereby changing the height of the second segment of the conveying mechanism 3. An angle sensor is provided between the first support frame 1 and the second support frame 2 to detect the rotation angle of the second support frame 2. The material is placed on the loading frame 36, and as the conveying mechanism 3 operates, the material is automatically transported to the feeding port of the preforming machine, realizing automatic feeding. Through this structure, the feeding device of the present application can flexibly adapt to different feeding heights, thereby improving versatility and ease of use.

[0041] Reference Figure 1 and Figure 2Specifically, in the embodiment of the present application, the first section includes a first guide wheel 31 and a second guide wheel 32, which are respectively arranged at the two ends of the first support frame 1, and are used to support and guide the conveying member 35. The second section includes a third guide wheel 33 and is arranged at an end of the second support frame 2 away from the first support frame 1, and is also used to support and guide the conveying member 35. The conveying member 35 is wound around the first guide wheel 31, the second guide wheel 32 and the third guide wheel 33 to form a continuous conveying path. In order to ensure the stability of the conveying member 35 during the rotation process, a fourth guide wheel 34 is further arranged below the rotation connection between the first support frame 1 and the second support frame 2, which contacts the bottom side of the conveying member 35 to support the conveying member 35.

[0042] The conveyor 35 forms a stable conveying path under the support and guidance of the first guide wheel 31, the second guide wheel 32, the third guide wheel 33 and the fourth guide wheel 34. The material is placed on the loading rack 36 and is stably transported to the feeding port of the preforming machine as the conveyor 35 operates.

In order to further optimize the structure, the piston rod of the hydraulic cylinder 41 is arranged to face upward, so that the piston rod is only subjected to the downward pressure, making the lifting process more stable and reliable.

[0047] According to the actual feeding height requirement, the extension amount of the hydraulic cylinder 41 is controlled to adjust the rotation angle of the connecting rod 42, thereby controlling the height of the second support frame 2.
