In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

As shown in fig. 1-4, the utility model provides a material breaking alarm device of an extruder, which is a part of a feeding device, and comprises a bracket 2, a rubber guiding roller 3, a signal sending wheel 5, a proximity switch 7, an alarm and a controller, wherein the bracket 2 is arranged near a feeding hopper 1.

The rubber guide roller 3 is pivoted on the bracket 2, and the rubber guide roller 3 pulls the rubber strip to pass through; the transmitting wheel 5 is arranged on the rubber roller 3, the transmitting wheel 5 is circumferentially provided with a bulge 51 and a tooth groove 52 at intervals, and the bulge 51 and the groove 52 form a sawtooth-like structure.

The proximity switch is arranged on the adjacent side of the signal transmitting wheel 5, pulse signals are formed when the proximity switch senses the protrusion and the groove of the signal transmitting wheel 5, and the controller is in communication connection with the proximity switch and the alarm. The glue stock is put on the tray and is moved by the extruder from A to B, and when the glue stock moves forward, the glue stock is pressed on the glue guide roller 33 by self weight so as to drive the glue guide roller 3 to rotate. So, when the material is present, the rubber guiding roller 3 rotates, the signal transmitting block arranged on the rubber guiding roller rotates synchronously, the outer circle of the signal transmitting block is in a saw-tooth structure, when the rubber guiding roller 3 rotates, the signal transmitting block rotates synchronously, the saw-tooth protrusions and the proximity switch approach to have signals, when the groove and the proximity switch approach to have no signals, when the signal transmitting block rotates continuously, the proximity switch continuously transmits pulse signals, and under the condition, the material is considered to be present and the rubber guiding roller operates normally.

When the material is broken, the rubber guide roller 3 stops rotating, the signaling block also stops rotating, the working condition proximity switch does not form a pulse signal, the material is considered to be broken, the alarm at the feeding hopper 1 of the extruder can give an alarm to prompt an operator, and the material breaking alarm is synchronously displayed on the operation screen.

According to the embodiment, whether the rubber guide roller rotates or not is detected through the characteristic design of the signal transmission wheel, whether the rubber material is reversely pushed onto the rubber guide roller or not is detected, the structural design is simple, and whether the rubber material is broken or not can be timely fed back.

In some embodiments, the signaling wheel 5 is a gear; specifically, an inner hole is formed in the middle of the signaling wheel 5, the inner hole defines a key groove, and the signaling wheel 5 is fixed on the rubber guiding roller 3 through the key groove. Illustratively, the rubber guiding roller 3 is provided with a step matched with the key groove on the shaft, and a gland 6 is formed at the end.

In this embodiment, the bracket 2 includes a left mounting plate and a right mounting plate which are mounted relatively, the left and right sides of the rubber guiding roller 3 are mounted on the left mounting plate and the right mounting plate in a rotating manner through deep groove ball bearings 4, one end of the rubber guiding roller 3 is provided with a signaling wheel 5, and a proximity switch is mounted at the bottom of the signaling wheel 5.
