Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of die cutting machine, more particularly to a glue anvil roller locking brake device. BACKGROUND

[0002] In the existing printing machinery field, the die cutting machine is one of the key equipment, which is used for accurate cutting and punching of paper and other materials. During the die cutting process, accurate control of die cutting pressure is crucial to ensure die cutting quality.

[0003] In the traditional die cutting process, the cutting of paper or other materials will produce instantaneous high impact force. If these impact forces are not effectively controlled, they will be transmitted to the die cutting pressure regulating motor, causing motor damage or reducing its service life. When the printing machine is die cutting, a large reaction force will be generated instantaneously, which will seriously damage the die cutting pressure regulating motor, causing the die cutting pressure regulating motor to be damaged.

[0004] In the existing technology, the glue anvil roller usually does not have an effective locking mechanism, and the glue anvil roller may vibrate and displace due to the reaction force, which not only affects the die cutting quality, but also may cause damage to the die cutting pressure regulating motor. In order to overcome these defects, a glue anvil roller locking brake device is proposed, which controls the lifting and falling of the rack through the cylinder to realize the locking of the gear, thereby effectively controlling the impact and vibration in the die cutting process, protecting the die cutting pressure regulating motor from damage, and improving the stability and efficiency of the die cutting process. SUMMARY

[0005] The present application aims to solve the technical problem that the glue anvil roller of the die cutting machine in the existing technology does not have an effective locking mechanism, and the glue anvil roller may vibrate and displace due to the reaction force, causing damage to the die cutting pressure regulating motor.

[0006] To achieve the above purpose, the utility model provides the following technical scheme:

[0007] A glue anvil roller locking brake device, comprising a gear, a rack and a cylinder, the gear is installed on the glue anvil roller; the rack is located on the outside of the gear, one end of the rack is rotatably connected to the end of the piston rod of the cylinder, and the other end is rotatably connected to the locking plate pin;

[0008] The rack is lifted by the cylinder to lock the locking plate pin, when the rack is lifted, it does not contact the gear, and the gear rotates freely, when the rack falls, it locks the gear so that the gear cannot rotate, thereby preventing the gear from rotating due to the reaction force during the die cutting process and stabilizing the entire glue anvil roller system.

[0009] The locking gear can make the pressure in the whole die cutting process more evenly distributed on the rubber anvil roller, instead of concentrated in a small part, so as to reduce the damage caused by pressure concentration. By locking the gear, the impact and vibration in the die cutting process can be effectively controlled, and the die cutting pressure regulating motor is protected from damage.

[0010] As preferred, the fixed end of the air cylinder is fixedly installed on the air cylinder tail pin, and the movable end is rotatably connected to one end of the rack.

[0011] As preferred, an arc-shaped groove coaxial with the gear is formed on the rack, and the gear teeth on the gear are distributed in the arc-shaped groove. The arc-shaped groove and the gear are matched in shape, which can ensure the accurate alignment of the gear when it is locked, and improve the meshing accuracy of the whole system.

[0012] As preferred, the gear is keyed connected with the rubber anvil roller. The key connection provides a firm connection between the gear and the rubber anvil roller, ensuring that the gear does not rotate relative to the rubber anvil roller during die cutting.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are that: the rubber anvil roller locking brake device, the air cylinder drives the rack to lift and fall with the locking plate pin as the center under the support of the air cylinder tail pin, the gear can rotate when the rack is lifted, and the gear cannot rotate when the rack falls, the rubber anvil roller is locked after the pressure is adjusted, so as to reduce the reaction force generated during die cutting and protect the die cutting pressure regulating motor.

[0014] The locking gear can effectively absorb and disperse the impact force generated during die cutting, reduce the direct impact on the die cutting pressure regulating motor, and thus protect the motor from damage. The locking gear makes the whole rubber anvil roller system more stable, avoids displacement or vibration caused by impact force, and improves the die cutting precision and the accuracy of repeated positioning. By locking the gear, the pressure can be more evenly distributed on the rubber anvil roller, reducing local damage or deformation caused by pressure concentration. After the gear is locked, the vibration of the rubber anvil roller system can be reduced, the stability of the die cutting process is improved, and the service life of the equipment is prolonged.

[0017] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made, belong to the scope of protection of the present application.

[0018] The accompanying drawings are referred to in the description of the embodiments of the present application. Figure 1 The present application is further described in detail,

[0019] The embodiment of the present application discloses a rubber roller locking brake device, which comprises a gear 3, a rack 2 and a cylinder 1, the gear 3 is installed on the rubber roller; the gear 3 is connected with the rubber roller by a key, the key connection provides a firm connection between the gear 3 and the rubber roller, ensuring that the gear 3 does not rotate relative to the rubber roller during the die cutting process. The key connection can effectively transmit high torque, which is very important for the possible instantaneous high load in the die cutting process. The key connection reduces the micro-motion between the gear 3 and the rubber roller, improves the stability and precision of the die cutting process. The key connection is a common connection method, easy to manufacture and install, and easy to check and replace during maintenance.

[0020] The rack 2 is located on the outside of the gear 3, one end of the rack 2 is rotatably connected to the piston rod end of the cylinder 1, and the other end is rotatably connected to the locking plate pin 5; the fixed end of the cylinder 1 is fixedly installed on the cylinder tail pin 4, and the movable end is rotatably connected to one end of the rack 2. The fixed end installed on the cylinder tail pin 4 can provide stable support for the cylinder 1, ensuring that the cylinder 1 does not move during operation, increasing the reliability of the entire system. The movable end is rotatably connected to one end of the rack 2, so that the linear motion of the cylinder 1 can be effectively converted into the rotary motion of the rack 2, thereby realizing the locking or release of the gear 3. An arc-shaped groove 6 coaxial with the gear 3 is formed on the rack 2, and the teeth on the gear 3 are distributed in the arc-shaped groove 6. The arc-shaped groove 6 and the gear 3 are matched in shape, which can ensure the accurate alignment of the gear 3 when locked, and improve the meshing accuracy of the entire system. The arc-shaped groove 6 reduces the gap between the rack 2 and the gear 3, thereby reducing the motion error and impact caused by the gap. The design of the arc-shaped groove 6 increases the contact area of the rack 2 and the gear 3, and improves the contact strength and stability.

[0021] The cylinder 1 drives the rack 2 to lift and drop the locking plate pin 5, the rack 2 is not in contact with the gear 3 when it is lifted, and the gear 3 rotates freely, the rack 2 is locked when it is lowered, so that the gear 3 cannot rotate, thereby preventing the gear 3 from rotating due to the reaction force during the die cutting process and stabilizing the entire rubber roller system.

[0022] During the die cutting process, an impact force is generated when the paper or other material is cut. If the gear 3 is free to rotate, this impact force is transmitted to the entire transmission system, including the die cutting pressure regulating motor. After the gear 3 is locked, this impact force is absorbed and dispersed, reducing the reaction force transmitted to the die cutting pressure regulating motor. After the gear 3 is locked, the stability of the anvil roller system is increased, and displacement or vibration does not occur due to the impact during the die cutting process, which can reduce damage to the die cutting pressure regulating motor. Locking the gear 3 can make the pressure during the entire die cutting process more evenly distributed on the anvil roller, rather than concentrated in a small part, which can reduce damage caused by pressure concentration. During the die cutting process, the anvil roller can vibrate due to the reaction force if the gear 3 is not locked. Locking the gear 3 can reduce this vibration, thereby reducing damage to the die cutting pressure regulating motor. In summary, by locking the gear 3, the impact and vibration during the die cutting process can be effectively controlled, and the die cutting pressure regulating motor can be protected from damage.

[0023] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still be modified to the technical solutions recorded in the foregoing embodiments, or to some of the technical features of the equivalent replacement, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included within the scope of the present application.
