Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically a safety protection device for a cutting machine. Background Technology

[0002] Cutting machines are indispensable equipment in some light industries. Traditionally, cutting machines are machines that use the force of mechanical movement to press against a die to punch and shape non-metallic materials. Modern cutting machines have undergone some changes, incorporating advanced technologies such as high-pressure water jets and ultrasonic waves into leather cutting technology, but these devices are still generally categorized as cutting machines.

[0003] Currently, materials are mostly moved manually when cutting materials with a cutting machine. However, if the cutting machine is accidentally triggered or malfunctions during manual movement, it can easily lead to injury. Furthermore, if the cutting machine applies excessive pressure when pressing down on the material or if there is a malfunction, the cutting blade may fall off and fly out, which can easily injure the operator. Therefore, this application proposes a safety protection device for cutting machines to protect the workers. Utility Model Content

[0004] The purpose of this invention is to provide a safety protection device for a cutting machine to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for a cutting machine, comprising a base 1 at the bottom, a column 3 in the middle, and an upper support 5 at the top, with a hydraulic cylinder 6 located on the top of the upper support 5 and its output end connected to a cutting blade 4. The upper support 5 is characterized by having symmetrically arranged linear rails 7 on one side, which are connected to a protective door 8. A protective device assembly 11 and a start handle 13 are located on the base 1 on the same side. The protective device assembly 11 contains a linkage switch mechanism, ensuring that the start handle 13 is fully closed before the hydraulic cylinder 6 can be energized.

[0006] Furthermore, the linkage switch mechanism includes a first contact switch 2, a second contact switch 17, and an insulating plate 15. The first contact switch 2 is fixed inside the upper part of the base 1. The insulating plate 15 is supported inside the base 1 by a rotating shaft 12. The second contact switch 17 is located at the front end of the insulating plate 15 and below the first contact switch 2. The second contact switch 17 is provided with a wire 16 connected to the start handle 13.

[0007] Furthermore, the protective device assembly 11 is provided with a fixing groove 10 of the same size as the protective door 8, and the tail end of the insulating plate 15 is located below the fixing groove 10.

[0008] Furthermore, the second contact switch 17 is a cylinder, and the first contact switch 2 is provided with a contact groove 9 that mates with the second contact switch 17.

[0009] Furthermore, the protective device assembly 11 is provided with a wire hole 14 through which the wire 16 passes.

[0010] This utility model has the following beneficial effects: Through a contact switch mechanism, it prevents the cutter holder from shifting downwards and causing injury to people when the cutting machine malfunctions due to misoperation or mechanical failure. Simultaneously, during machine operation, an electric push rod can move the baffle downwards to the front of the cutting platform, blocking the cutting mechanism and platform. This prevents the cutter from falling off and injuring people in case of excessive pressure or mechanical failure, thus providing excellent protection for operators and preventing injury during operation. The observation window allows operators to clearly see the material cutting process. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1 This utility model provides a technical solution: a safety protection device for a cutting machine, including a base 1 at the bottom, a column 3 in the middle and an upper support 5 at the top, a hydraulic cylinder 6 at the top of the upper support 5, and a cutting blade 4 connected to the output end.

[0015] The upper support base 5 has symmetrically arranged linear rails 7 on one side, which are connected to the protective door 8. Meanwhile, the base 1 has electric push rods on both sides to drive the protective door 8 to move up and down. The protective door 8 has an observation window made of transparent material.

[0016] On the same side as the protective door 8, the base 1 is equipped with a protective device assembly 11 and a start handle 13. The protective device assembly 11 contains a linkage switch mechanism, which allows the start handle 13 to be energized to control the operation of the hydraulic cylinder 6 only when the protective door 8 is fully lowered. The linkage switch mechanism includes a first contact switch 2, a second contact switch 17, and an insulating plate 15. The first contact switch 2 is fixed to the upper part of the base 1. The insulating plate 15 is supported in the base 1 by a rotating shaft 12. The second contact switch 17 is located at the front end of the insulating plate 15 and below the first contact switch 2. The second contact switch 17 is cylindrical. The first contact switch 2 has a contact groove 9 that mates with the second contact switch 17. The second contact switch 17 has a wire 16 that connects to the start handle 13. The protective device assembly 11 has a wire hole 14 through which the wire 16 passes.

[0017] Meanwhile, the protective device assembly 11 has a fixing groove 10 of the same size as the protective door 8, and the tail end of the insulating plate 15 is located below the fixing groove 10. When the electric push rod drives the protective door 8 to fall completely, the insulating plate 15 is pressed to rotate around the pivot 12, so that the second contact switch 17 contacts the first contact switch 2, energizing the start handle 13, so that the worker can control the start handle 13 to start the hydraulic cylinder 6 of the cutting machine.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
