AI Technical Summary
During the transportation of the spiral machine, ultra-high cargo is prone to falling off. The existing height-limited frame device will physically block the cargo, causing damage to the outer box. The device is far from the cargo port, which increases the walking distance and time-consuming of people.
A spiral machine transportation height limit frame device is designed, including a frame, assembly line to conveyor belt, conveyor belt movable seat, assembly line to injection mechanism, control cabinet and physical height limit rod. The device detects the height of the cargo through the assembly line emitting mechanism. Extra-high cargo will trigger the shutdown signal and alarm light to ensure that the cargo can pass within the appropriate height range.
It effectively limits the entry of ultra-high and ultra-wide cargo into the spiral machine, reduces the risk of cargo drop and damage, reduces the distance of people moving, improves transportation safety, and ensures the safety of operation through sound and light prompts and confirmation devices.

Between the conveyor belt pair 2 for the assembly line and the frame 1, there is a conveyor belt movable seat 3. The conveyor belt movable seat 3 is fixedly connected to the frame 1. The conveyor belt pair 2 for the assembly line is movably connected to the conveyor belt movable seat 3. Above the frame 1, there is a pair of shooting mechanisms 4 for the assembly line. The pair of shooting mechanisms 4 for the assembly line is fixedly connected to the frame 1. On one side of the frame 1, there is a control cabinet 5. The control cabinet 5 is fixedly connected to the frame 1. Both the pair of shooting mechanisms 4 for the assembly line and the conveyor belt pair 2 for the assembly line are electrically connected to the control cabinet 5. Above the frame 1, there is also a physical height-limiting rod 6. The physical height-limiting rod 6 is fixedly connected to the frame 1. At the upper end of the frame 1, there is an indicator light 8. The indicator light 8 is fixedly connected to the frame 1. The indicator light 8 is electrically connected to the control cabinet 5. On the frame 1, there is also an emergency stop and reset switch 7. The emergency stop and reset switch 7 is fixedly connected to the frame 1. The emergency stop and reset switch 7 is electrically connected to the control cabinet 5. The pair of shooting mechanisms 4 for the assembly line includes a transmitting end 41 and a receiving end 42. The transmitting end 41 and the receiving end 42 are respectively arranged on both sides of the frame 1.
[0024] The control circuit of the control cabinet includes a power switch FQ1, a transformer V1, push-button switches SB1 and SB2, relays KA1 and KA2, and an indicator light H1.
[0025] The power supply part is provided by a transformer (V1), which outputs alternating current. The power switch (FQ1) controls the on-off of the entire circuit. There are two push-button switches (SB1 and SB2), which are respectively used to control different relays. There are two relays (KA1 and KA2). Each relay has two normally open contacts and one normally closed contact. The coils of relays KA1 and KA2 are respectively controlled by push-buttons SB1 and SB2. There is an indicator light (H1), which is used to indicate the state of the circuit.

[0030] Working principle of the utility model: Goods are transported through the assembly line. If the passing goods exceed the specified height, when passing through the height limit frame, the assembly line's opposed light is blocked, and the device emits a stop signal, activates the emergency stop button through the contactor, and at the same time, the signal alarm lights of the height limit frame and the assembly line sound. After the warehouse personnel unload the over-height goods, then press the emergency stop reset button, and the height limit opposed device resumes the normal operation of the assembly line only when it detects that there is no goods blocking.
[0031] Restrict over-height and over-width goods from entering the screw conveyor, reduce the risk of goods falling, avoid damage caused by goods collision. The height and width limit of goods is detected at the loading entrance of the assembly line, reducing the walking distance of personnel. When over-height goods enter, the sound and light alarm goes off, reminding personnel in the first time. After the over-height and over-width goods are removed, the confirmation device needs to be pressed to resume the operation of the assembly line to ensure personnel safety.
[0032] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model.
