Description

Technical Field

[0001] The utility model relates to the technical field of rubber production, in particular to a feeding device for a rubber extruder. Background Art

[0002] Rubber extruder is a basic equipment in the rubber industry and one of the key equipment that affects product quality. It plays a very important role in the production process of tires and rubber products. The development of foreign rubber extruders has gone through the stages of plunger extruder, screw-type hot feed extruder, ordinary cold feed extruder, main and secondary thread cold feed extruder, cold feed exhaust extruder, pin cold feed extruder, and composite extruder.

[0003] In the current existing technology, the work of the rubber extruder is completed by manually putting the rubber raw materials into the feed port of the rubber extruder. This not only has low work efficiency, but also cannot ensure the uniformity of feeding, and is prone to material breakage or blockage. It is also easy to cause accidents such as the operator's limbs being involved in the feed port, posing a huge safety hazard.

[0004] After searching the existing Chinese patents: a feeding device for a rubber extruder (Announcement No.: CN214521815U), including: a supporting device, a driving device and a first driving roller; the supporting device includes a supporting plate and a side plate fixedly connected to the supporting plate, and the two ends of the supporting plate are respectively a feeding end for allowing the rubber raw material to enter the supporting plate and a discharging end that can correspond to the feeding port; the first driving roller is located above the supporting plate and the axis is parallel to the supporting plate, the first driving roller can be rotatably connected to the side plate, and pressed against the rubber raw material located on the supporting plate, and the driving device is connected to the first driving roller in a transmission manner; the driving device can drive the first driving roller to rotate, so that the first driving roller drives the rubber raw material located on the supporting plate to move toward the discharging end. It is not only highly safe, but also feeds evenly, can avoid the phenomenon of material breaking or blocking, and can also improve production efficiency.

[0005] Although the above patent uses a driving device to drive the first driving roller to rotate, so that the first driving roller drives the rubber raw material on the supporting plate to move toward the discharge end, the technical solution is not only highly safe, but also uniform in feeding, and can avoid the occurrence of material breakage or blockage, and can also improve production efficiency. However, the device has the disadvantage that the feeding device is installed at a high position. When the internal components of the feeding device are damaged or need to be repaired, it is necessary to climb onto the frame or use a ladder to repair it, which makes the operation very inconvenient and increases the safety risks of the maintenance personnel.

[0006] Therefore, it is necessary to invent a feeding device for rubber extruder to solve the above problems. Utility Model Content
