Description

Technical Field

[0001] The utility model relates to the technical field of roller detection of a flip mold-pulling machine, in particular to a roller detection device for a flip mold-pulling machine. Background Art

[0002] The flip mold-stripping machine is one of the key equipment used in the resin sand molding process. Its function is to separate the mold from the sand mold. The success or failure of this process directly affects the quality of the molding sand.

[0003] In the existing flip mold-lifting machine, for example, a flip mold-lifting machine disclosed in the utility model patent with application number 201621009941.2, the utility model enters the inside of the flip mold-fitting machine through the mold box through the conveying roller, and then the lifting device is started, and the lifting device drives the conveying roller and the mold box on the conveying roller to rise, wherein the template clamping device clamps the template, and then the flip device flips the O-shaped frame. When the mold box is at the bottom again, the template is separated from the mold box, and the conveying roller is started to transport the mold box forward out of the O-shaped frame, and then the flip device is started again and the O-shaped frame is flipped. At this time, the template is at the bottom, and the conveyor belt transports the template out. The flip mold-fitting machine of this embodiment has a compact structure, and the entire operation process is stable, which avoids the occurrence of production safety accidents.

[0004] However, in the process of detecting the roller table of the flipping and stripping machine, the prior art does not accurately detect the outer edge of the sand box. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a roller detection device for a flip mold machine, which is provided with a roller detection device so that the entire upper surface of the sand box is detected. Even if the sand box has a horizontal inclination during the rising process, it will not affect the detection, and the detection is more accurate.

[0006] The utility model discloses a roller detection device for a flip mold-pulling machine, comprising a head driving device; further comprising a tail roller, two sets of tensioning wheels, a roller detection device, a transmission belt, multiple sets of supporting rollers and a sand box, wherein the tail roller is mounted on the head driving device, the two sets of tensioning wheels are mounted on the head driving device, the roller detection device is mounted on the head driving device, the multiple sets of supporting rollers are mounted on the lower end of the head driving device, the transmission belt is covered and mounted on the head driving device, the tail roller, the two sets of tensioning wheels and the multiple sets of supporting rollers, and the sand box is arranged on the lower side of the head driving device; when the sand box contacts the roller detection device during the rising process, the induction roller is higher than the transmission belt by a distance H=10 mm, and when the sand box continues to rise and is in the same plane with the transmission belt, detection is performed through the roller detection device, and if the support roller is damaged due to excessive weight of the medium during the process of conveying the medium, the transmission belt will collapse and the roller detection device will transmit a signal to the PLC, and the equipment will stop running.

[0007] Preferably, the head driving device is the driving body; the device is powered by the head driving device.

[0008] Preferably, the tail roller is mounted on the head driving device; the tail roller moves in coordination with the head driving device.

[0009] Preferably, two sets of tension wheels are installed on the head driving device; the transmission belt is tensioned by the tension wheels.

[0010] Preferably, the roller detection device includes a sensing roller, two groups of lower brackets, two groups of upper brackets, two groups of springs, two groups of sensing rods and two groups of sensing switches. The two groups of lower brackets are rotatably installed at both ends of the sensing roller, and each group of lower brackets is equipped with a group of upper brackets through a group of springs. The two groups of upper brackets are connected to the head driving device, and each group of lower brackets is equipped with a group of sensing rods. The two groups of sensing switches are installed on the head driving device, and each group of sensing switches is in contact with a group of sensing rods. When the sand box contacts the roller detection device during the rising process, the sensing roller is higher than the conveyor belt by a distance H=10 mm. When the sand box continues to rise and is in the same plane with the conveyor belt, the spring is compressed, and the sensing rod is also raised, and the sensing switch contacts the sensing rod. If the support roller is damaged due to excessive weight of the medium during the conveying process, the conveyor belt will collapse and press the sensing roller. After the springs on the lower brackets at both ends of the sensing roller are compressed to a certain amount, the sensing rods at both ends will rise with the sensing roller. When the sensing switch senses the rising sensing rod, it transmits a signal to the PLC and the equipment stops running.

[0011] Preferably, the conveyor belt is mounted on the head driving device, the tail drum, two sets of tensioning wheels and multiple sets of supporting rollers, and is in contact with the sand box through the conveyor belt.

[0012] Preferably, the support rollers are installed on the head driving device; the conveyor belt is supported by multiple groups of support rollers to make the conveyor belt smoother.

[0013] Preferably, the sand box is arranged at the lower side of the head driving device; the sand box is the material to be detected.

[0014] Compared with the prior art, the utility model has the following beneficial effects: when the sand box contacts the roller detection device during the rising process, the induction roller is higher than the conveyor belt by a distance H=10 mm. When the sand box continues to rise and is in the same plane with the conveyor belt, the roller detection device is used for detection. If the support roller is damaged due to excessive weight of the medium during the conveying process, the conveyor belt will collapse and the roller detection device will transmit a signal to the PLC, and the equipment will stop running.
