Description

Technical Field

[0001] This utility model belongs to the field of automatic protection technology for die-cutting machines, specifically relating to a linkage stop mechanism to prevent foreign objects from entering. Background Technology

[0002] To prevent foreign objects from falling onto the die-cutting machine and affecting its operation, baffles are usually installed on the frame of the die-cutting machine's processing section to form a processing chamber for protection. Glass is also installed on the baffles so that workers can observe the internal operating conditions. However, after the die-cutting machine is assembled, debugged, or maintained, if workers leave tools or parts inside the processing chamber, once the machine is started, the foreign objects are likely to collide with the high-speed rotating rollers, cutting blocks, and other components in the processing area, causing them to splatter and collide with the baffles. The lower end of the baffles is usually the most vulnerable section. The process of workers discovering the foreign objects and rushing to the switch to stop the machine takes a long time, and if the machine cannot be stopped in time, the foreign objects will bounce back to the processing area multiple times inside the processing chamber, causing serious damage to the equipment. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a linkage shutdown mechanism to prevent foreign objects from entering, which can stop the machine in time when a foreign object is left in the processing chamber and comes into contact with the moving parts, thereby reducing the degree of equipment damage and lowering maintenance costs.

[0004] The specific technical solution adopted in this utility model is as follows:

[0005] A linkage-based shutdown mechanism for preventing foreign object entry includes a baffle, and importantly, it also includes a signal triggering end located outside the processing chamber. The baffle is hinged to the machine frame, and the baffle contacts the signal triggering end via a linkage component to trigger a shutdown signal.

[0006] A return spring is also provided between the baffle and the frame.

[0007] The linkage component includes a rotating shaft and a swing arm. The baffle and the swing arm are respectively fixed at the inner and outer ends of the rotating shaft. The baffle is hinged to the frame via the rotating shaft. The cantilever end of the swing arm is used to contact the signal trigger end to trigger a stop signal.

[0008] The signal trigger terminals are respectively set on the swing path of the cantilever end and are arranged adjacent to the cantilever end.

[0009] One end of the reset spring is connected to the frame, and the other end is connected to the swing arm.

[0010] The frame is provided with a set of limiting rods, which are used to limit the initial position of the swing arm and the position of the trigger signal trigger end, respectively.

[0011] The section of the baffle that is most vulnerable to impact has an arc-shaped or zigzag-shaped structure.

[0012] The beneficial effects of this utility model are:

[0013] This utility model uses a baffle that is hinged to the frame. A linkage component is also connected to the baffle. When the machine is turned on, foreign objects splash and collide with the baffle, causing the baffle to swing relative to the frame. The baffle drives the linkage component to change its position. The linkage component contacts the signal trigger end to trigger a stop signal. This can quickly trigger a stop signal when foreign objects splash, avoiding multiple splashes of foreign objects from breaking the glass on the baffle or foreign objects from repeatedly contacting the moving parts, which would cause more equipment damage.

[0014] A return spring is installed between the baffle and the frame. After the baffle is hit by a foreign object, the return spring releases its elastic potential energy and drives the baffle to automatically return to its initial position to continue to provide protection, preventing foreign objects from flying out of the processing chamber. No manual reset is required, ensuring that the mechanism can be reused.

[0015] The baffle and the swing arm are fixed to both ends of the rotating shaft. The rotating shaft accurately transmits the movement of the baffle to the swing arm. The structure is simple and reliable, ensuring the stability and timeliness of the trigger stop signal and avoiding stop delay. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] Example 1, such as Figure 1As shown, this utility model relates to a linkage-based shutdown mechanism to prevent foreign object ingress, including a baffle 1 and a signal triggering end 2. The signal triggering end 2 is located outside the processing chamber, and the baffle 1 is hinged to the machine frame. The baffle 1 contacts the signal triggering end 2 via a linkage component to trigger a shutdown signal. By replacing the conventional baffle fixed to the machine frame with a baffle 1 hinged to the machine frame, when a foreign object splashes into the processing chamber and contacts the baffle 1, the baffle 1 actuates and transmits the signal to the signal triggering end via the linkage component, quickly triggering a shutdown signal and reducing equipment damage. The signal triggering end 2 is a mechanical switch, preferably a micro switch.

[0022] The micro switch is connected to the controller of the die-cutting machine. When the controller receives the electrical signal that the micro switch is closed due to the triggering of the linkage component, it cuts off the power supply to the die-cutting machine, thereby triggering the stop action.

[0023] Furthermore, a return spring 3 is also provided between the baffle 1 and the frame. After the baffle 1 is hit by a foreign object, the return spring 3 releases its elastic potential energy, driving the baffle 1 to automatically return to its initial position to continue to provide protection, preventing foreign objects from still flying out of the processing chamber. No manual reset is required, ensuring that the mechanism can be reused.

[0024] Furthermore, the linkage component includes a rotating shaft 4 and a swing arm 5. The baffle 1 and the swing arm 5 are respectively fixed to the inner and outer ends of the rotating shaft 4. The baffle 1 is hinged to the frame via the rotating shaft 4. The cantilever end 6 of the swing arm 5 is used to contact the signal trigger end 2 to trigger a stop signal. The baffle 1 and the swing arm 5 are fixed to both ends of the rotating shaft 4. The rotating shaft 4 accurately transmits the movement of the baffle 1 to the swing arm 5. The structure is simple and reliable, ensuring the stability and timeliness of triggering the stop signal and avoiding stop delays.

[0025] Furthermore, the signal triggering end 2 is respectively set on the swing path of the cantilever end 6 and is set adjacent to the cantilever end 6. The signal triggering end 2 is set close to the cantilever end 6. Once the baffle 1 drives the swing arm 5 to swing, the cantilever end 6 can quickly and timely contact the signal triggering end 2, ensuring that the stop signal is triggered in a timely and accurate manner.

[0026] One end of the return spring 3 is connected to the frame, and the other end is connected to the swing arm 5. Connecting the return spring 3 and the swing arm 5 outside the processing chamber reduces the space occupied inside the processing chamber and facilitates installation. Preferably, both ends of the baffle 1 are hinged to the frame via a pivot 4. A swing arm 5 is mounted on each pivot 4, and each swing arm 5 is connected to the return spring 3. The signal trigger end 2 only needs to be located on one side of the baffle 1.

[0027] Example 2, as Figure 2As shown, preferably, a set of limiting rods 7 are provided on the frame. The limiting rods 7 are respectively set on the upper and lower sides of the swing arm 5. When the baffle 1 is impacted, the lower end swings upward. The limiting rod 7 located on the lower side of the swing arm 5 is spaced apart from the swing arm 5. The limiting rod 7 limits the swing angle of the swing arm 5 to prevent the swing arm 5 from violently impacting the signal trigger terminal 2 when the baffle 1 is subjected to a large impact force, thus preventing damage to the signal trigger terminal 2. Subsequently, under the action of the baffle 1's own weight and the return spring 3, the baffle 1 drives the swing arm 5 to return to its original position. The limiting rod 7 located on the upper side of the swing arm 5 limits the initial position of the swing arm 5 to prevent the baffle 1 from swinging excessively.

[0028] The impact-prone section 8 of the baffle 1 has an arc-shaped, zigzag, or inclined structure. When the impact-prone section 8 is arc-shaped, it is preferably a concave arc. When the splashed item comes into contact with the concave arc, it easily moves along the curve of the concave surface. During this process, the splashed item loses its kinetic energy through multiple collisions and friction with the concave surface, eventually becoming trapped inside the concave surface or sliding down along the edge of the concave surface, making it difficult to bounce back to the processing area; Figure 2 As shown, when the baffle 1 has a zigzag structure, the splashed items collide with one side of the zigzag structure and reflect off the other side. The reflection direction changes, and the splashed items collide with the easily impacted section 8 multiple times, and the rebound kinetic energy is consumed, effectively preventing the splashed items from reflecting back to the processing area. In this embodiment, the easily impacted section 8 has a zigzag structure; as Figure 3 As shown, when the vulnerable section 8 of the baffle 1 is inclined, an acute angle is formed between the lower end of the vulnerable section 8 and the worktable. When the splashed items collide with the inclined surface of the vulnerable section 8, their reflection direction changes, thus deviating from the processing area, or even being clamped on the worktable by the vulnerable section 8 on the falling baffle 1, preventing the splashed items from bouncing back to the processing area.
