Description

Technical Field

[0001] The utility model relates to the technical field of feeding cylinders, in particular to a feeding cylinder with a residual material detection function. Background Art

[0002] The feeding cylinder of an injection molding machine is used to temporarily store injection molding raw materials. To maintain the uniformity of the feeding of the injection molding machine, a certain amount of raw materials must always be kept in the feeding cylinder. Therefore, it is necessary to replenish the raw materials in the feeding cylinder in a timely manner.

[0003] Currently, the existing feeding cylinder lacks a residual material detection device. As a result, the replenishment operation of the feeding cylinder requires manual observation or the replenishment time is calculated by backtracking based on the processing amount of the injection molding machine. If there are changes in the processing parameters, it is often necessary to recalculate. Based on this, this solution provides a feeding cylinder with a residual material detection function. By adding a residual material detection mechanism to the feeding cylinder, the residual material amount in the feeding cylinder is detected, and the automatic replenishment is assisted by a suction machine. Summary of the Utility Model

[0004] The utility model aims to at least solve the problem of the lack of a residual material detection function in the prior art.

[0005] This solution provides a feeding cylinder with a residual material detection function, which is achieved by the following specific technical means: including a cylinder body, both opposite sides of the side wall of the cylinder body are fixed with mechanism seats, one of the two groups of mechanism seats is provided with a signal transmitter, and the other group is provided with a signal receiver; further including a self-inductive cleaning mechanism located inside the cylinder body and between the two groups of mechanism seats, and the self-inductive cleaning mechanism is used to clean the ends of the signal transmitter and the signal receiver.

[0006] Preferred Technical Solution 1: Surplus signal transmitters are respectively arranged at the upper and lower ends of one group of the mechanism seats, and surplus signal receivers are respectively arranged at the upper and lower ends of the other group of the mechanism seats, and the two groups of surplus signal transmitters and the two groups of surplus signal receivers correspond one by one.

[0007] Preferred Technical Solution 2: The self-inductive cleaning mechanism includes an induction plate and a cleaning frame. The induction plate is located directly below the top opening of the material barrel. At the same time, the convex rod fixed on the side of the induction plate is connected to the mechanism seat through an elastic member. The scraping plate fixed on the cleaning frame scrapes and cleans when vibrating against the ends of the signal transmitter and the signal receiver.

[0008] Preferred Technical Solution 3: Two scraping plates are arranged on the cleaning frame corresponding to the two groups of signal transmitters and signal receivers.

[0009] Preferred Technical Solution 4: The induction plate is located in the middle of the mechanism seat.

[0010] Preferred Technical Solution Five: The top surface of the induction plate is an upwardly convex arc structure, so that the raw materials falling onto the induction plate can slide down smoothly.

[0011] Adopting the above structure enables this solution to have the following beneficial effects:

[0012] 1. By setting a signal transmitter and a signal receiver on the barrel body, the remaining amount of raw materials in the barrel body can be automatically detected, and the replenishment of raw materials can be controlled in a timely manner;

[0013] 2. The setting of the self-inductive cleaning mechanism can clean the ends of the signal transmitter and the signal receiver, avoiding the influence of debris dropped by the injection molding raw materials adhering to the ends on the detection effect;

[0014] 3. Based on the self-service principle, the setting of the induction plate can collect the power of the falling injected raw materials to provide power for the cleaning action, and there is no need to set up an additional power source. Description of the Drawings

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0022] Please refer to Figure 1 - Figure 2, A feeding cylinder with a waste material detection function, including a cylinder body 1. On both opposite sides of the side wall of the cylinder body 1, mechanism seats 2 are fixedly installed. One of the two groups of mechanism seats 2 is provided with a signal transmitter 21 (using existing technology) that can emit infrared light signals, and the other group is provided with a signal receiver 22 (using existing technology) that is directly opposite and can receive infrared light signals. The signal receiver 22 receives the signal emitted by the signal transmitter 21 when there is no obstruction in the middle.

[0023] Signal transmitters 21 are respectively arranged at the upper and lower ends of one group of mechanism seats 2, and corresponding signal receivers 22 are respectively arranged at the upper and lower ends of the other group of mechanism seats 2. The two groups of signal transmitters 21 and the two groups of signal receivers 22 are in one-to-one correspondence. The group of signal transmitter 21 and signal receiver 22 located at the lower side cooperate to detect the lowest remaining amount in the cylinder body 1, and the group of signal transmitter 21 and signal receiver 22 located at the upper side cooperate to detect the highest remaining amount in the cylinder body 1.

[0024] Please refer to Figure 2 - Figure 4 , The feeding cylinder with a waste material detection function further includes a self-inductive cleaning mechanism 3 located inside the cylinder body 1 and arranged between the two groups of mechanism seats 2. The self-inductive cleaning mechanism 3 is used to clean the ends of the signal transmitter 21 and the signal receiver 22, maintain their working states, and prevent debris dropped from the injection molding raw materials from adhering to the ends and affecting the detection effect. The self-inductive cleaning mechanism 3 includes an induction plate 31. The induction plate 31 is located directly below the top opening of the cylinder body 1. At the same time, a convex rod 32 fixed to the side of the induction plate 31 is connected to the mechanism seat 2 through an elastic member 33. When injecting injection molding raw materials from the top opening of the cylinder body 1, the raw materials impact the induction plate 31, driving the induction plate 31 to vibrate up and down. The induction plate 31 is located in the middle of the mechanism seat 2, so that the induction plate 31 will not block the ends of the signal transmitter 21 and the signal receiver 22 when vibrating up and down. The elastic member 33 includes a vertical cylinder 331 fixed to the mechanism seat 2 and a sliding plate 332 sliding inside the vertical cylinder 331. A vertical rod 333 fixed to the sliding plate 332 slides out of the vertical cylinder 331 and is fixedly connected to the convex rod 32. A vibration spring 334 is connected between the sliding plate 332 and the end wall of the vertical cylinder 331. When injecting raw materials, the impact on the induction plate 31 drives the vibration spring 334 to undergo elastic deformation, thereby generating vibration and driving the cleaning frame 34 to vibrate up and down, achieving the technical effect of driving the scraper 35 to scrape and clean the ends.

[0025] It further includes a cleaning frame 34. The scraper 35 fixed to the cleaning frame 34 fits against the ends of the signal transmitter 21 and the signal receiver 22 and scrapes and cleans during vibration. Two groups of scrapers 4 are provided on the cleaning frame 34 corresponding to the two groups of signal transmitters 21 and signal receivers 22.

[0026] Please refer to Figure 2, a feeding cylinder with a waste material detection function. The top surface of the induction plate 31 is a convex arc structure, so that the raw materials falling on the induction plate 31 can slide smoothly.

[0027] Please refer to Figure 1 , a feeding cylinder with a waste material detection function. The feeding pipe provided at the top opening of the cylinder body is externally connected to a suction feeder. The suction feeder, the signal transmitter 21 and the signal receiver 22 are all connected to the controller provided on the mechanism base 2. After the controller receives the start signal and the transmitter 21 emits a signal, which is received by the signal receiver 22 and fed back to the controller, it is used to start and stop the suction feeder. When the depth of the raw materials in the barrel body 1 is lower than the lower signal transmitter 21 and signal receiver 22, the controller receives the signal and starts the suction feeder for filling. During the filling process, the raw materials impact the induction plate 31, causing the induction plate 31 to vibrate between the upper and lower groups of signal transmitters 21 and signal receivers 22, driving the scraper 34 to clean the ends of the signal transmitters 21 and signal receivers 22. When the raw materials reach the middle of the mechanism base 2 and are located below the upper signal transmitter 21 and signal receiver 22, the raw materials bury and press the induction plate 31, and no longer vibrate. After losing the impact force of the falling raw materials, the induction plate 31 no longer vibrates significantly. At this time, the scraper 35 is away from the signal transmitters 21 and signal receivers 22.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
