Description

Technical Field

[0001] The invention relates to the technical field of circular knife moulds, in particular to a circular knife mould capable of preventing a knife edge from being glued. Background Art

[0002] A circular knife mold is a mold used for cutting, usually consisting of a circular knife cutting edge and a mold base. The circular knife cutting edge is a key component for cutting workpieces. It is made of high-speed steel or carbide and has a sharp edge. Its angle determines the cutting quality and processing efficiency. The mold base is responsible for fixing the circular knife and is usually made of high-strength alloy material to ensure stability and durability. The working principle of the circular knife mold is to rely on the rotation and cutting force of the blade to cut the material. The rotation speed and cutting depth of the blade can be controlled by adjusting the knife seat and the knife holder, while the shape and size of the cut material depends on the shape and size of the blade. Circular knife molds are widely used in printing, packaging, shoemaking, leather processing, electronic products and other industries. They have the characteristics of fast cutting speed, high precision and easy operation, and can significantly improve production efficiency.

[0003] The existing circular knife mold has significant deficiencies in preventing the blade from sticking to the material. In order to prevent the blade from sticking to the material during the cutting process, it is traditionally treated by manually applying the release agent. However, this method not only has certain safety hazards, because the operator needs to be in close contact with the sharp blade, which may cause accidental injuries if not careful. At the same time, manual application also greatly increases the labor burden of the personnel. It is not only inefficient, but also unevenly applied, making it difficult to ensure that each blade part can be fully covered with the release agent. In addition, this method is not convenient for automated production, which limits the improvement of production efficiency and cannot meet the requirements of modern industry for high precision, high efficiency and high safety. Therefore, we propose a circular knife mold that prevents the blade from sticking to the material. Summary of the invention

[0011] Preferably, the lower ends of the two inserting strips respectively penetrate into the interior of the two slots and contact the inner walls of the slots, and handles are fixedly mounted on both sides of the front surface of the receiving tray.

[0012] A circular knife mold operation method for preventing knife edge from sticking glue comprises the following steps:

[0013] Step one, first, pour the release agent into the storage barrel through the liquid inlet pipe, then turn on the stirring motor to drive the rotating rod to drive the stirring blade to stir the release agent in the storage barrel to keep its performance stable so that it can play a normal release effect in subsequent use, then start the liquid pump, extract the release agent through the liquid extraction pipe and send it into the liquid inlet plate through the liquid outlet pipe. At this time, the release agent flows through the nozzles at the bottom of the liquid inlet plate to the foam cotton sleeve on the surface of the roller. After the foam cotton sleeve contacts the release agent, it absorbs and stores it. In the process of spraying the release agent, the release agent that is not sprayed on the foam cotton sleeve will fall into the receiving tray to avoid waste of resources.

[0014] Step 2. Then, control the operation of the adjustment motor, and the adjustment motor drives the stud to rotate. Since the stud is threadedly connected to the nut plate, the nut plate will drive the first bracket to move to the left through the connecting plate along the rotation direction of the stud. The connecting plate moves on the guide column to ensure the stability of its movement until the foam sleeve on the first bracket contacts the surface of the circular knife mold body.

[0015] Step three, then, the circular knife mold body is driven to rotate through the driving mechanism. During the rotation process, the circular knife mold body contacts with the foam sleeve and squeezes it to a certain extent. Due to the elastic effect of the spring, the first bracket on one side of the movable plate and the foam sleeve on the roller are always in contact with the surface of the circular knife mold body. No matter how the surface shape of the circular knife mold body changes when it rotates, the foam sleeve can maintain a good contact state. In the process of the circular knife mold body rotating and cutting the material, the roller is driven to rotate by friction. At this time, the foam sleeve The release agent will gradually transfer to the circular knife mold body to form a thin release film, which effectively prevents adhesion between the blade and the material, thereby ensuring the smooth progress of the cutting process and the cutting quality. After the die-cutting is completed, the motor is controlled to reverse again to move the foam sleeve to the right until the hollow plate is limited by the limit block and the motor is stopped. At this time, the foam sleeve is located at the bottom of the nozzle to facilitate subsequent spraying. Finally, the operator can use the handle to pull the receiving tray and the insert strip at the bottom out of the slot to deal with the release agent collected on the receiving tray.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The circular knife mold for preventing the blade from sticking to glue is designed with a storage barrel, a rotating rod, a stirring blade, a stirring motor, a liquid pump, a liquid extraction pipe, a liquid outlet pipe, a liquid inlet plate, a nozzle, a rotating roller and a foaming cotton sleeve. The stirring motor drives the rotating rod to drive the stirring blade to continuously stir the release agent in the storage barrel, which helps to ensure that the release agent maintains its performance and stability during storage, which not only significantly improves the production efficiency, but also starts the liquid pump to extract the release agent and spray it on the foaming cotton sleeve through the nozzle. The foaming cotton sleeve can absorb the release agent and can apply the release agent to the circular knife mold when it contacts the circular knife mold body. The blade of the main body effectively prevents the problem of glue on the blade during the cutting process, realizes the automated and continuous release agent spraying and coating process, and reduces the safety hazards and labor burden caused by manual brushing. The design of the stud, adjustment motor, nut plate, connecting plate, hollow plate, spring and movable plate further enhances the flexibility and adaptability of the present invention. By controlling the forward and reverse rotation of the adjustment motor, the contact distance between the foaming cotton sleeve and the circular knife mold body can be accurately adjusted. This function is crucial for cutting materials of different thicknesses and different materials and circular knife mold bodies in different working states. It ensures that the foaming cotton sleeve can always fit tightly and appropriately on the blade, and will not increase the cutting resistance due to being too tight, nor will it affect the release effect due to being too loose. At the same time, the elastic effect of the spring plays a key role in this design. It gives the movable plate and the first bracket and the roller thereon a certain floating ability, so that the foaming cotton sleeve can be adaptively adjusted according to the slight vibration or shape change of the circular knife mold body during the cutting process. This dynamic fitting feature not only ensures that the release agent can be continuously and evenly coated on the blade, but also effectively extends the release effect. The service life of the foam sleeve is prolonged, and the cost and maintenance burden caused by frequent replacement are reduced. The design of the slot, insert and receiving tray fully takes resource conservation and environmental protection into consideration. During the spraying process of the release agent, the release agent that is not absorbed by the foam sleeve will drip onto the receiving tray, avoiding the waste of release agent and ground pollution. The operator can regularly pull the receiving tray out of the slot, recycle and reuse the release agent therein, or properly dispose of it in accordance with relevant regulations, thereby achieving maximum resource utilization and environmentally friendly protection.

[0033] A circular knife mold operation method for preventing knife edge from sticking glue comprises the following steps:

[0034] Step one, first, pour the release agent into the storage barrel 3 through the liquid inlet pipe 7, then turn on the stirring motor 6 to drive the rotating rod 4 to drive the stirring blade 5 to stir the release agent in the storage barrel 3 to keep its performance stable so that it can play a normal release effect in subsequent use, then start the liquid pump 8, extract the release agent through the liquid extraction pipe 9 and send it into the liquid inlet plate 12 through the liquid outlet pipe 10. At this time, the release agent flows to the foam sleeve 30 on the surface of the roller 29 through the nozzles 13 at the bottom of the liquid inlet plate 12. After the foam sleeve 30 contacts the release agent, it absorbs and stores it. In the process of spraying the release agent, the release agent that is not sprayed on the foam sleeve 30 will fall into the receiving tray 34 to avoid waste of resources.

[0035] Step 2, then, control the adjustment motor 16 to run, and the adjustment motor 16 drives the stud 15 to rotate. Since the stud 15 is threadedly connected to the nut plate 17, the nut plate 17 will drive the first bracket 28 to move to the left through the connecting plate 18 along the rotation direction of the stud 15.

Due to the elastic effect of the spring 24, the first bracket 28 on one side of the movable plate 25 and the foam sleeve 30 on the roller 29 are always in contact with the surface of the circular knife mold body 35. No matter how the surface shape of the circular knife mold body 35 changes when it rotates, the foam sleeve 30 can maintain a good contact state. In the process of the circular knife mold body 35 rotating and cutting the material, the roller 29 is driven to rotate by friction. At this time, the foam sleeve 30 The release agent on the circular knife mold body 35 will gradually transfer to the circular knife mold body 35 to form a thin release film, which effectively prevents the adhesion between the blade and the material, thereby ensuring the smooth progress of the cutting process and the cutting quality. After the die-cutting is completed, the adjustment motor 16 is controlled to reverse again to move the foam sleeve 30 to the right until the hollow plate 23 is limited by the limit block 22 and the adjustment motor 16 stops operating.

[0037] In summary: the circular knife mold for preventing blade from sticking glue, through the design of storage barrel 3, rotating rod 4, stirring blade 5, stirring motor 6, liquid pump 8, liquid extraction pipe 9, liquid outlet pipe 10, liquid inlet plate 12, nozzle 13, rotating roller 29 and foaming cotton sleeve 30, the stirring motor 6 drives the rotating rod 4 to drive the stirring blade 5 to continuously stir the release agent inside the storage barrel 3, which helps to ensure that the release agent maintains its performance and stability during storage, which not only significantly improves the production efficiency, but also starts the liquid pump 8 to extract the release agent and spray it on the foaming cotton sleeve 30 through the nozzle 13. The foaming cotton sleeve 30 can absorb the release agent and when it comes into contact with the circular knife mold body 35, it can The release agent can be applied to the blade of the circular knife mold body 35, which effectively prevents the problem of glue on the blade during the cutting process, realizes the automated and continuous release agent spraying and coating process, and reduces the safety hazards and labor burden caused by manual brushing. The design of the stud 15, the adjustment motor 16, the nut plate 17, the connecting plate 18, the hollow plate 23, the spring 24 and the movable plate 25 further enhances the flexibility and adaptability of the present invention. By controlling the forward and reverse rotation of the adjustment motor 16, the contact distance between the foaming cotton sleeve 30 and the circular knife mold body 35 can be accurately adjusted.

It ensures that the foam sleeve 30 can always fit tightly and appropriately on the blade, and will not increase the cutting resistance due to being too tight, nor will it affect the release effect due to being too loose. At the same time, the elastic effect of the spring 24 plays a key role in this design. It gives the movable plate 25 and the first bracket 28 and the roller 29 thereon a certain floating ability, so that the foam sleeve 30 can be adaptively adjusted according to the slight vibration or shape change of the circular knife mold body 35 during the cutting process.

Handles (37) are fixedly mounted on both sides of the front surface of the receiving tray (34).

8. A method for operating a circular knife mold for preventing glue from sticking to the blade according to any one of claims 1 to 7, characterized in that: The steps include: Step 1, first, pour the release agent into the storage barrel (3) through the liquid inlet pipe (7), then turn on the stirring motor (6) to drive the rotating rod (4) to drive the stirring blade (5) to stir the release agent in the storage barrel (3) to keep its performance stable so that it can play a normal release effect in subsequent use, then start the liquid pump (8), extract the release agent through the liquid extraction pipe (9) and send it into the liquid inlet plate (12) through the liquid outlet pipe (10). At this time, the release agent flows through the nozzles (13) at the bottom of the liquid inlet plate (12) to the foaming cotton sleeve (30) on the surface of the roller (29). After the foaming cotton sleeve (30) contacts the release agent, it absorbs and stores it. In the process of spraying the release agent, the release agent that is not sprayed on the foaming cotton sleeve (30) will fall into the receiving tray (34) to avoid waste of resources; Step 2, then, control the regulating motor (16) to run, the regulating motor (16) drives the stud (15) to rotate, because the stud (15) is threadedly connected to the nut plate (17), therefore, the nut plate (17) will drive the first bracket (28) to move to the left side through the connecting plate (18) along the rotation direction of the stud (15), and the connecting plate (18) moves on the guide column (20) to ensure the stability of its movement until the foaming cotton sleeve (30) on the first bracket (28) contacts the surface of the circular knife mold body (35); Step three, then, the circular knife mold body (35) is driven to rotate by the driving mechanism. During the rotation process, the circular knife mold body (35) contacts with the foam sleeve (30) and squeezes it to a certain extent. Due to the elastic effect of the spring (24), the first bracket (28) on one side of the movable plate (25) and the foam sleeve (30) on the roller (29) are always in contact with the surface of the circular knife mold body (35). No matter how the surface shape of the circular knife mold body (35) changes when it rotates, the foam sleeve (30) can maintain a good contact state. During the process of the circular knife mold body (35) rotating and cutting the material, the roller (29) is driven to rotate by friction. At this time, the foam sleeve (30) ) will gradually transfer to the circular knife mold body (35) to form a thin release film, which effectively prevents adhesion between the blade and the material, thereby ensuring the smooth progress of the cutting process and the cutting quality. After the die-cutting is completed, the regulating motor (16) is controlled to reverse again to move the foam sleeve (30) to the right until the hollow plate (23) is limited by the limit block (22) and the regulating motor (16) stops operating. At this time, the foam sleeve (30) is located at the bottom of the nozzle (13) to facilitate subsequent spraying. Finally, the operator can use the handle (37) to pull the receiving tray (34) and the insert (33) at the bottom out of the slot (32), thereby processing the release agent collected on the receiving tray (34).
