Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic particle processing, especially to a material droop alarm device. BACKGROUND

[0002] In the process of recycling plastic particles, the crushed plastic particles need to be sent into a screw extruder through a screw extruder. In the extruder, the plastic particles are first heated by a heating device, causing the plastic to gradually melt. At the same time, the rotation of the screw stirs, mixes, and extrudes the plastic, making it reach a uniform plasticizing state.

[0003] The plasticized plastic is pushed by the screw and extruded through a die head with a specific shape. The shape of the die head determines the shape of the extruded plastic, for example, if round plastic particles are to be produced, the die head is designed as a round hole. The extruded plastic strip is regular in shape and has a certain continuity. Then the plastic strip is cooled and shaped by a circulating water pool.

[0004] In general, the plastic strip after heating and extrusion will fall into the water pool for cooling, but in the process of processing, some plastic strips may fall downward to form a drooping shape and fall onto the ground between the screw extruder and the water pool. If there is no pre-reporting and pre-warning of the drooping plastic strip, the resource will be wasted after the screw extruder works for a period of time. UTILITY MODEL CONTENT

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model.

[0020] Please refer to Figures 1-3 The utility model provides a kind of material drooping alarm device technical scheme: a kind of material drooping alarm device, including spiral extruder body 1 and circulating cooling water pool 2, the circulating cooling water pool 2 is located in the side of spiral extruder body 1 and there is a certain interval between circulating cooling water pool 2 and spiral extruder body 1, it is equipped with porous extrusion orifice head 11 on the spiral extruder body 1, it is equipped with drooping alarm mechanism 3 on the circulating cooling water pool 2, the drooping alarm mechanism 3 is located in the feed end downside of circulating cooling water pool 2 and is located in the position below porous extrusion orifice head 11.

[0021] In the process of use, when plastic strip is extruded into circulating cooling water pool 2, drooping alarm mechanism 3 will not issue alarm to show that spiral extruder body 1 is in normal condition when extruding several plastic strips outward;

[0022] When the position of plastic strip is not transported into circulating cooling water pool 2 but plastic strip is drooping downward to drooping alarm mechanism 3, drooping alarm mechanism 3 will issue prompt and alarm, prompting staff to have abnormal condition, and staff handles drooping plastic strip.

[0023] The utility model can realize the alarm to drooping plastic strip, and product quality can be guaranteed: drooping plastic strip can appear folding, distortion and other problems in extrusion process, to make product to produce defect.Timely alarm can make operator take measures quickly, avoid the generation of these defects, improve the quality and good product rate of product;

[0024] Improve production efficiency: if plastic strip droops seriously and is not discovered in time, it can lead to extruder blockage or plastic strip fracture, so that production is forced to interrupt.Drooping alarm mechanism 3 can issue alarm in the early stage of problem, so that operator has enough time to handle, avoids production interruption, reduces time waste and production loss caused by shutdown, thereby maintaining the continuity of production, and improving overall production efficiency;

[0025] Protect equipment safety: serious plastic strip droop can make plastic strip rub or collide with the parts of extruder, to cause damage to equipment.For example, plastic strip can be scraped to head, die orifice and other parts, to lead to the wear or damage of these parts.Drooping alarm mechanism 3 can find plastic strip droop problem in time, avoid this situation, prolong the service life of equipment;

[0026] And reduce production costs: plastic strip sagging problem if not timely solved, may cause plastic strip can not be used normally, resulting in waste of raw materials. Through the timely warning of the sagging alarm mechanism 3, the operator can quickly adjust the production process, reduce the waste caused by the sagging of the plastic strip, reduce the consumption of raw materials, thereby reducing the production cost.

[0027] In this embodiment, referring to Figure 2 The rotating shaft 32 is located at the rear end of the blanking plate 33. After the end of the blanking plate 33 falls downward, the two reset torsional springs 34 are reset, so that the blanking plate 33 rotates back to the horizontal state from the inclined state.

[0028] In this embodiment, referring to Figure 3 The sagging alarm mechanism 3 includes a mounting bracket 31, a rotating shaft 32 and a blanking plate 33. The mounting bracket 31 is vertically arranged on the circulating cooling water tank 2. The two ends of the rotating shaft 32 are connected to the mounting bracket 31. The rotating shaft 32 is rotatably connected to the mounting bracket 31. The blanking plate 33 is horizontally arranged on the rotating shaft 32. The two ends of the rotating shaft 32 are respectively provided with reset torsional springs 34. The two ends of the reset torsional springs 34 are respectively connected to the rotating shaft 32 and the mounting bracket 31.

[0029] When the position of the blanking plate 33 is in the horizontal state, it means that the blanking plate 33 is in the initial state. When the sagging plastic strip falls into the blanking plate 33, the blanking plate 33 rotates on the mounting bracket 31 through the rotating shaft 32 due to the action of gravity, so that the blanking plate 33 is in the state of tilting to one end. After the plastic strip is cleaned by the worker, the two reset torsional springs 34 work to make the blanking plate 33 in the inclined state rotate to the horizontal state, so as to receive the sagging plastic strip and alarm next time.

[0030] In this embodiment, referring to Figure 2 The rear side of the blanking plate 33 is provided with a position sensor 4. The mounting bracket 31 is provided with an electrically connected alarm 5 above the position sensor 4. The model of the position sensor 4 is Positek P101.

[0031] When the plastic strip on the blanking plate 33 tilts downward, the position sensor 4 on the other end of the blanking plate 33 moves upward. When the position of the position sensor 4 rotates upward to the position of the alarm 5, the position sensor 4 will transmit the position signal to the alarm 5, and the alarm 5 will alarm and remind the worker. Then the worker will take out the sagging plastic strip from the blanking plate 33.
