Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and more specifically relates to an automatic feeding device for a quenching furnace. Background Technology

[0002] Quenching is an important part of continuous production lines. In order to ensure the production rhythm of the entire production line and guarantee the yield rate, it is crucial that the parts are fed into the quenching furnace at a certain speed and evenly. That is, the feeding mechanism needs to feed at a uniform speed. The traditional feeding method relies on manual pouring of parts from the bucket into the hopper. The hopper uses a vibration mechanism to make the parts fall more evenly onto the conveyor belt, and then the conveyor belt lifts the parts and sends them into the furnace. The hopper is also equipped with a weight sensor to monitor the weight of the remaining parts in the hopper in real time.

[0003] However, due to the fact that the parts in the hopper will move left and right, collide with each other, roll or jump during the vibration and falling process, the actual number of parts that fall on the conveyor belt conveying area (formed by two adjacent baffles on the upper and lower sides of the conveyor belt) is not the same each time. That is, the number of parts falling into the quenching furnace each time varies. In other words, the current feeding mechanism is not precise enough, which affects subsequent production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic feeding device for quenching furnaces, ensuring that each conveying zone has the same number of parts, thus avoiding disruption to subsequent production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for a quenching furnace, the automatic feeding device being located at the lower end of a conveyor belt, the automatic feeding device including multiple feeding supports, feeding hoppers being provided on the feeding supports, a vibrator being provided at the bottom of the feeding hoppers, a receiving hopper being provided below the discharge ports of the multiple feeding hoppers, the discharge port of the receiving hopper being located above the conveyor belt, a counting camera being provided above the discharge port of the receiving hopper, the receiving hopper being supported by a receiving support, the receiving hopper being hinged to the receiving support, and a driving mechanism being provided between the receiving hopper and the receiving support, driving the receiving hopper to tilt its discharge port downward toward the conveyor belt or tilt upward.

[0006] Furthermore, the drive mechanism includes a cylinder, the cylinder body of which is hinged to the receiving bracket, the piston rod of which is hinged to the bottom of the receiving hopper, and a rotating shaft is provided at the bottom of the receiving hopper, the rotating shaft being rotatably connected to the receiving bracket.

[0007] Furthermore, a counting sensor is provided at the bottom of the discharge port of the upper hopper, and the counting sensor is connected to the feeding bracket via a connecting rod.

[0008] Furthermore, the discharge port of the feeding hopper is tilted downwards toward the receiving hopper.

[0009] Furthermore, the interior of the feeding hopper is conical, with the smallest possible discharge port.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: First, parts are poured into multiple feeding hoppers. When the feeding hoppers vibrate, the parts fall onto the receiving hopper. The receiving hopper tilts downward. When the parts in the receiving hopper pass under the counting camera, the counting camera counts them. Then, they fall onto the conveyor belt. When the count reaches the amount of one conveying cycle, the receiving hopper tilts slightly upward to prevent subsequent parts from falling. At the same time, the vibrator stops vibrating, and the parts on the feeding hopper stop falling into the receiving hopper until the next conveying zone of the conveyor belt moves to below the discharge port of the receiving hopper. Then, the receiving hopper tilts downward again and continues to feed, so that each conveying zone has the same number of parts, avoiding affecting the subsequent production rhythm.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0015] Reference Figure 1 The present invention will be further described below.

[0016] An automatic feeding device for a quenching furnace is located at the lower end of a conveyor belt 1. The automatic feeding device includes multiple feeding supports (not shown in the attached drawings), each feeding support is equipped with a feeding hopper 2, and a vibrator 3 is installed at the bottom of the feeding hopper 2. A receiving hopper 4 is installed below the discharge port of the multiple feeding hoppers 2. The discharge port of the receiving hopper 4 is located above the conveyor belt 1, and a counting camera 5 is installed above the discharge port of the receiving hopper 4. The receiving hopper 4 is supported by a receiving support 6, and the receiving hopper 4 is hinged to the receiving support 6. A driving mechanism 7 is provided between the receiving hopper 4 and the receiving support 6 to drive the receiving hopper 4 so that its discharge port tilts downward toward the conveyor belt 1 or tilts upward.

[0017] like Figure 1 As shown, during feeding, parts are first poured into multiple feeding hoppers 2. The parts are vibrated by the vibrator 3 of the feeding hopper 2 and fall from its outlet onto the receiving hopper 4. At this time, the receiving hopper 4 tilts downwards via the drive mechanism 7. When the parts on the receiving hopper 4 pass under the counting camera 5, the counting camera 5 counts, and then the parts fall from the outlet onto the conveyor belt 1. When the count of the counting camera 5 reaches the amount for one conveying cycle, the drive mechanism 7 drives the receiving hopper 4 to rotate, tilting it slightly upwards to prevent further parts from falling. Simultaneously, the vibrator 3 stops vibrating, and the parts on the feeding hopper 2 stop falling into the receiving hopper 4. When the next conveying zone of the conveyor belt 1 moves to below the outlet of the receiving hopper 4, the receiving hopper 4 tilts downwards again, ensuring that each conveying zone has the same number of parts, avoiding disruption to subsequent production.

[0018] Specifically, the number of parts in each conveying zone can fluctuate within a certain range. If the part is large, it can be plus or minus one from the standard quantity; if the part is small, it can be plus or minus two.

[0019] In this preferred embodiment, the driving mechanism 7 includes a cylinder, the cylinder body of which is hinged to the receiving bracket 6, the piston rod of which is hinged to the bottom of the receiving hopper 4, and a rotating shaft is provided at the bottom of the receiving hopper 4, the rotating shaft being rotatably connected to the receiving bracket 6.

[0020] like Figure 1 As shown in this example, preferably, a counting sensor 8 is provided at the bottom of the discharge port of the feeding hopper 2. The counting sensor 8 is connected to the feeding bracket through a connecting rod, and the number of items falling is detected by the counting sensor 8.

[0021] like Figure 1 As shown in this example, preferably, the discharge port of the feeding hopper 2 is slightly tilted downward toward the receiving hopper 4 to improve the efficiency of parts falling during vibration, and at the same time, it can be stopped by friction when the vibration stops.

[0022] like Figure 1As shown in this example, preferably, the interior of the feeding hopper 2 is conical, with the smallest discharge port, so that a maximum of two parts can fall from the discharge port at the same time, avoiding excessive storage in the receiving hopper 4 due to too many parts falling at once.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
