Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment safety protection devices, in particular to a safety protection device for an automatic forming machine. Background Art

[0002] With the rapid development of industrial automation, automatic forming machines have been widely used in the manufacturing industry, such as tire manufacturing, injection molding, packaging material production and other fields. The high efficiency and precision of this type of equipment have greatly improved production efficiency and product quality. However, during the operation of automatic forming machines, due to their complex mechanical structure and high-speed moving parts, there are many safety hazards. In particular, if personnel enter the operating danger zone of the equipment, once a danger occurs, it will pose a serious threat to the personal safety of the operator.

[0003] Although some of the automatic forming machines on the market are equipped with certain safety protection measures, such as mechanical fences and safety doors, these mechanical fences and safety doors have problems such as poor adaptability and slow response speed, and cannot play the role of prompts and warnings. In order to achieve better safety protection effects, infrared safety gratings are usually used for protection operations. These infrared safety gratings transmit and receive signals. When a human body or object enters the area, it blocks the infrared beam and triggers an emergency stop signal to achieve a safety protection effect.

[0004] However, since infrared safety gratings work by transmitting signals through a transmitter and receiving signals through a receiver, most infrared safety gratings have transmitters and receivers fixed on corresponding frames. This results in the height of the transmitter or receiver being unable to be adjusted. When the frame is directly fixed on the corresponding ground, if the ground is uneven, direct installation will cause the height of the transmitter and receiver to be misaligned, further resulting in the inability to receive signals between the transmitter and receiver, affecting the normal use of the infrared safety grating and causing inconvenience to the user. In view of this, we propose a safety protection device for an automatic forming machine. Utility Model Content

[0028] Specifically, a fixed base 39 is fixedly mounted on the bottom ends of the first vertical frame 30 and the second vertical frame 33 . The fixed base 39 is fixedly mounted on an external concrete base by a plurality of fastening bolts to achieve a fixed support effect.

[0029] In this embodiment, an elastic washer 37 is sleeved on the stud 351 , and the nut 38 is pressed against the elastic washer 37 . The elastic washer 37 can prevent the nut 38 from loosening.

[0030] Specifically, material holes 10 are provided on both end plates of the main body 1 of the automatic forming machine. The material holes 10 are connected to the outside world. The two material holes 10 are used for feeding and discharging raw materials respectively.

[0031] Furthermore, protection components 2 are provided on both the left and right sides of the automatic forming machine body 1. The protection component 2 includes two left and right guide rails 20 that are symmetrical to each other and fixedly installed on the side of the automatic forming machine body 1. The material hole 10 is located between the two guide rails 20. A bottom plate 21 is fixedly installed at the bottom of the two guide rails 20. The protection component 2 also includes a cylinder 22 fixedly installed on the side of the automatic forming machine body 1. A sealing plate 23 is provided on the telescopic axis of the cylinder 22. The sealing plate 23 is located between the two guide rails 20. Guide plates 24 are fixedly installed on both the left and right sides of the sealing plate 23. The guide plates 24 are located in the guide rails 20 and are slidably connected to the guide rails 20. When the sealing plate 23 slides downward to the bottom surface against the bottom plate 21, the sealing plate 23 blocks the front side of the material hole 10 for sealing operation, thereby achieving a protective effect.

[0032] In addition, a rectangular plate 221 is fixedly mounted on the end of the telescopic shaft of the cylinder 22, and the blocking plate 23 is fixedly mounted on the bottom surface of the rectangular plate 221 by a plurality of fastening bolts, so as to facilitate the fixing, installation and disassembly operations.

[0034] It is worth noting that during specific operations, when an object blocks the signal between the infrared transmitter 36 and the infrared receiver 31 on the front side, the control host 32 controls the alarm module 34 to perform a voice prompt operation, prompting the personnel to step back. When the personnel continues to move forward and blocks the signal between the infrared transmitter 36 and the infrared receiver 31 on the rear side, the control host 32 controls the automatic forming machine body 1 to disconnect the power supply and stop working.

[0035] Finally, it should be noted that the infrared transmitter 36, infrared receiver 31, control host 32 and alarm module 34 involved in the present invention are all universal standard parts or parts known to those skilled in the art.

The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the art.

[0036] When the safety protection device of the automatic forming machine of the present invention is in use, the first vertical frame 30 and the second vertical frame 33 are fixedly installed around the processing dangerous area of the automatic forming machine body 1, and the sliding sleeve 35 is slid up and down to adjust the height of the infrared emitter 36 according to the height of the infrared receiver 31, so that the position of the infrared emitter 36 corresponds to the position of the infrared receiver 31. After adjustment, the nut 38 is tightened to complete the fixation, and then the infrared grating 3 is connected to the external power supply to make the whole machine work. In addition, as the material is processed in the automatic forming machine body 1, at this time, the cylinder 22 is started and made to work. When the cylinder 22 works, the telescopic shaft on it extends and drives the blocking plate 23 to move downward. At this time, the blocking plate 23 blocks the front side of the material hole 10 for blocking operation. When material feeding and discharging is required, the cylinder 22 is started and made to work. When the cylinder 22 works, the telescopic shaft on it shortens and drives the blocking plate 23 to move upward. At this time, the material hole 10 is exposed to the outside, and the material feeding and discharging operations can be carried out normally.

[0037] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
