Description

Technical Field

[0001] The utility model relates to the field of packaging industry, in particular to a trimming device for a full-automatic die-cutting machine. Background Art

[0002] A rotary die-cutter is a cutting machine. Since the roller of a rotary die-cutter rotates continuously when it is working, its production efficiency is the highest among all types of die-cutting machines and it is often used for mass production. The working parts of both the platen and the pressing mechanism of the rotary die-cutter are cylindrical. When working, the paper feed roller sends the cardboard between the die-pressing roller and the pressure roller, which clamps it and performs die-cutting on the roller. One rotation of the die-cutting roller is a working cycle. The die-cutting plate used in the existing rotary die-cutting machine is an arc plate fixed on the die-cutting roller, and the die-cutting knife on the die-cutting plate is usually a closed ring with a specific shape, and a groove is formed on the inner side of the die-cutting knife. Therefore, the waste after die-cutting is easily stuck in the groove, resulting in the waste not being able to fall automatically, affecting the subsequent die-cutting processing of the cardboard.

[0003] At present, a Chinese patent with authorization announcement number CN210389497U discloses a waste cleaning module of a rotary die-cutting machine, including a base, a waste box and a workbench, a pressure roller and a die-cutting roller are arranged on the workbench, and the pressure roller and the die-cutting roller are connected with a driving assembly, a dust collecting box and a brush roller are arranged on one side of the pressure roller, a die-cutting plate and are arranged on the die-cutting roller, and an ejection assembly is arranged in the inner cavity. The utility model drives the pressure roller and the die-cutting roller to rotate synchronously and in the opposite direction through the driving assembly, and the die-cutting knife on the die-cutting plate is used to die-cut the cardboard, and the ejection assembly moves with the die-cutting roller, and the roller drives the moving rod and the ejector rod to move outward through the action of the cam, so that the ejector rod extends from the ejection hole, and the waste is ejected from the die-cutting plate, so that the waste falls into the waste box, and the waste is prevented from being stuck in the groove formed by the die-cutting knife; the side wall of the pressure roller is cleaned by the bristles on the brush roller to improve the cleaning effect.

[0004] The above-mentioned existing technical solutions have the following defects: the pressure roller and the die-cutting roller need to be modified, or new pressure rollers and die-cutting rollers need to be customized, and they cannot adapt to the various types of rotary die-cutting machines currently on the market, and waste cleaning during the die-cutting process can easily cause waste to be mixed into the material. Utility Model Content

[0005] The purpose of the utility model is to provide a trimming device for a fully automatic die-cutting machine to solve the problems existing in the above-mentioned prior art.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A trimming device for a fully automatic die-cutting machine comprises a die-cutting machine body, a paper splicer and a waste discharge module, a conveyor belt is arranged on the top of the die-cutting machine body, the conveyor belt is used to transport materials from right to left to the waste discharge module, a paper splicer is fixedly installed on the top of the die-cutting machine body, and the waste discharge module is arranged on the left side of the paper splicer;

[0008] The waste discharge module comprises a shell and a limiting device, a front linear guide and a rear linear guide are arranged at intervals on the inner top of the shell, a first pneumatic telescopic rod is fixedly installed on the sliders of the front linear guide and the rear linear guide, a waste removal module is detachably installed on the bottom of the first pneumatic telescopic rod, and the limiting device is arranged between the front linear guide and the rear linear guide;

[0009] The limiting device includes a second pneumatic telescopic rod and a limiting plate. The top of the second pneumatic telescopic rod is fixedly installed on the inner top of the shell. The bottom of the second pneumatic telescopic rod is provided with a limiting plate, and the limiting plate is used to fix the die-cut material.

[0010] By adopting the above technical solution, the paper splicer is arranged after the waste cleaning module, so that the paper splicer can first stack the die-cut cardboard materials, and the number of cardboard materials can also be recorded during the stacking process. When a certain number of cardboard materials are accumulated, the cardboard materials are transported from the paper splicer to the waste discharge module through the conveyor belt. After being transported to the bottom of the limit device, the second telescopic rod will drop, and the limit plate will be used to support the pile of cardboard materials to fix them. At this time, the sliders on the front linear guide and the rear linear guide have slid to the specified position. During the telescopic movement of the first pneumatic telescopic rod at the bottom of the slider, the waste cleaning module is driven to clean the paper plate materials. The whole process does not need to be replaced or modified. The pressure roller and the die-cutting roller only need to replace the position of the paper splicer and add a waste discharge module. The waste discharge module is far away from the plate table and the pressure cutting mechanism of the die-cutting machine, so that the waste is not easy to be accidentally rolled into the cylinder or material during the waste cleaning process. The waste cleaning efficiency is much higher than that of manual hammering.

[0011] In a further embodiment, the waste stripping module is composed of a bracket and an air compressor;

[0012] The air compressor is arranged on one side of the workbench, one end of the bracket is fixedly connected to the air motor, the other end of the bracket is rotatably mounted with a secondary sprocket, a main sprocket is sleeved on the rotating shaft of the air motor, the main sprocket and the secondary sprocket are connected through a sprocket gear transmission, and the air inlet of the air motor is connected to the air outlet of the air compressor through an air pipe.

[0013] By adopting the above technical solution, the waste cleaning module is driven by a pneumatic motor, and the pneumatic motor is driven by an air compressor. The pneumatic motor is small in size, has a large output torque, can achieve instant forward and reverse rotation, has a long service life, and is very suitable for workplaces with high frequency of use. When started, the main sprocket mounted on the rotating shaft of the pneumatic motor will drive the sprocket and the secondary sprocket to rotate. During the rotation of the sprocket, it is released from the waste cleaning module of the cardboard material to complete the waste cleaning.

[0014] In a further embodiment, the sprocket includes a sprocket body and a chain, a plurality of grooves are evenly spaced on the surface of the chain, a sprocket body is embedded in each of the grooves, and the sprocket body is used to hook and pull waste materials connected to the material.

[0015] By adopting the above technical solution, the sprocket body will rotate with the rotation of the chain. When the teeth touch the waste connected to the material, it will be taken out of the material body and thrown to one side by the force of the chain rotation. Compared with manual waste removal with a hammer, the waste removal module can greatly improve work efficiency, shorten the waste removal cycle, and improve the yield rate.

[0016] In a further embodiment, a first receiving groove is provided on the front side of the inner top of the workbench, and a second receiving groove is provided on the rear side of the inner top of the workbench. The first receiving groove is used to accommodate waste cleaned by the waste cleaning module on the front linear guide rail, and the second receiving groove is used to accommodate waste cleaned by the waste cleaning module on the rear linear guide rail.

[0017] By adopting the above technical solution, since the width of the workbench at the waste discharge module is limited, when the material is fixed on the workbench by the limiting device, the waste cleaning areas on the front and rear sides of the material are suspended, and when the chain tooth body contacts the material, the waste thrown from the material will immediately fall into the first receiving groove and the second receiving groove.

[0018] In a further embodiment, the left ends of the first accommodating groove and the second accommodating groove are provided with openings, and the openings of the first accommodating groove and the second accommodating groove are both provided with collecting devices, and the collecting devices are used to recover the removed waste.

[0019] By adopting the above technical solution, the collecting device can extract the waste into the recycling system through the principle of vacuum adsorption. Whenever the waste cleaning module starts working, the collecting device also starts working to ensure that the waste inside the first storage tank and the second storage tank will not accumulate too much and affect the next waste cleaning.

[0020] In a further embodiment, a shock-absorbing cushion layer is provided on the top left side of the workbench.

[0021] By adopting the above technical solution, in order to reduce the impact of vibration on the workbench and the conveyor belt, a shock-absorbing pad is provided on the top of the workbench of the waste discharge module to reduce the vibration generated when the waste cleaning module contacts the material, and the first telescopic rod and the slider are also provided with a shock-absorbing pad to reduce the impact of vibration on the linear guide rail.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. Through the setting of the paper splicer and the waste stripping module, the position of the paper splicer can be changed so that the die-cutter can perform waste stripping operations at a position away from the pressure roller and the die-cutting roller. There is no need to modify or replace the pressure roller and the die-cutting roller. Just by changing the position of the paper splicer, the effect of reducing the impact of waste in the waste stripping process on the subsequent die-cutting accuracy can be achieved;

[0024] 2. Through the setting of the pneumatic motor and the sprocket, the pneumatic motor can be used to drive the main sprocket set on the bracket, thereby driving the sprocket and the auxiliary sprocket to rotate together. The chain is made of high-strength alloy steel, with strong wear resistance, long service life, and easy replacement. It can be repaired in time when a fault occurs. The sprocket body embedded in the chain will hook out and remove the waste paper edges in the process of contacting with the material, thereby achieving the effect of waste removal;

[0025] 3. Through the arrangement of the first receiving tank, the second receiving tank and the collecting device, the waste generated during the operation of the waste cleaning module can fall into the receiving tank, and then the collecting device arranged at the opening at the left end of the receiving tank is used for vacuum suction to continuously extract the waste from the receiving tank, thereby ensuring that the waste will not affect the next waste cleaning. At the same time, the waste is transported to the recycling device, thereby achieving the environmental protection effect of saving materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example:

[0034] like Figure 1-3As shown, a trimming device for a fully automatic die-cutting machine includes a die-cutting machine body 1, a workbench 9 and a waste discharge module 3. A conveyor belt is arranged on the top of the workbench 9, and the conveyor belt is used to transport materials to the waste discharge module 3 from right to left. A paper splicer 2 is fixedly installed on the top of the workbench 9, and the waste discharge module 3 is arranged on the left side of the paper splicer 2. A shock-absorbing cushion layer is arranged on the top of the left side of the workbench 9. The waste discharge module 3 includes a shell 31 and a limiting device 32. A front linear guide 4 and a rear linear guide 5 are arranged at intervals on the inner top of the shell 31. The sliders of the front linear guide 4 and the rear linear guide 5 are fixedly installed with a first pneumatic telescopic rod 6. The bottom of the first pneumatic telescopic rod 6 is detachably installed with a waste removal module 7. The limiting device 32 is arranged between the front linear guide 4 and the rear linear guide 5. 32 includes a second pneumatic telescopic rod 321 and a limiting plate 322. The top of the second pneumatic telescopic rod 321 is fixedly installed on the inner top of the shell 31, and the bottom of the second pneumatic telescopic rod 321 is provided with a limiting plate 322. The limiting plate 322 is used to fix the die-cut materials. After the die-cutting, the cardboard materials are first collected by the paper splicer 2. After the collection is completed, they are transported to the waste discharge module 3 by the conveyor belt. The limiting device 32 will fix the stacked cardboard materials, and then the waste cleaning devices at the bottom of the first pneumatic telescopic rod 6 on the front and rear sides will contact the materials and remove the waste. By setting the paper splicer 2 before the waste discharge module 3, the waste during waste cleaning can be kept away from the pressure roller and the die-cutting roller, thereby preventing the waste from affecting the accuracy of die-cutting and subsequent die-cutting.

[0035] like Figure 1-4As shown, the waste cleaning module 7 includes a bracket 71 and an air compressor 10. The air compressor 10 is arranged on one side of the workbench 9. One end of the bracket 71 is fixedly connected to an air motor 72. The other end of the bracket 71 is rotatably installed with a secondary sprocket 74. A main sprocket 73 is sleeved on the rotating shaft of the air motor 72. The main sprocket 73 and the secondary sprocket 74 are transmission-connected by a sprocket 75. The air inlet of the air motor 72 is connected to the air outlet of the air compressor 10 through an air pipe. The sprocket 75 includes a sprocket body 751 and a chain 752. A plurality of grooves are evenly spaced on the surface of the chain 752. A sprocket body 751 is embedded in each groove. The sprocket body 751 is used to hook and pull the waste connected to the material. A first accommodating groove is provided on the front side of the inner top of the workbench 9, and a second accommodating groove is provided on the rear side of the inner top of the workbench 9. The first accommodating groove is used to accommodate the waste cleaning module 7 on the front linear guide rail 4. The second receiving groove is used to receive the waste cleaned by the waste cleaning module 7 on the rear linear guide rail 5. The left ends of the first receiving groove and the second receiving groove are provided with openings. The openings of the first receiving groove and the second receiving groove are provided with collecting devices 8. The collecting device 8 is used to recycle the removed waste. The pneumatic motor 72 of the waste cleaning module 7 is driven by the air compressor 10. The pneumatic motor 72 is small in size and has a large output torque. It can realize instant forward and reverse rotation and is suitable for workplaces with high frequency of use. The chain 752 is made of high-strength alloy steel with strong wear resistance and is easy to replace. It can be repaired in time when a fault occurs, so that the overall service life of the waste cleaning device is very long. The efficiency of waste cleaning by mechanical devices is much higher than that of manual waste cleaning, and the probability of generating waste is lower. The waste in the waste cleaning process will fall into the receiving grooves on the front and rear sides, and be extracted from the receiving grooves by the collecting device 8 for more environmentally friendly recycling.

[0036] Specific implementation process: after the die-cutting is completed, the material will be transported to the paper splicer 2 through the conveyor belt. The paper splicer 2 stacks the die-cut materials and transports them to the waste discharge module 3 after accumulating a certain amount. The stacked materials are fixed at the specified position by the limit device 32. During the descent of the first telescopic rod, the waste removal module 7 is started. When the waste removal module 7 contacts the material, the pneumatic motor 72 driven by the air compressor 10 drives the sprocket 75 to rotate, so that the sprocket body 751 contacts the waste material and removes the waste material from the material. The removed material moves along the direction of rotation of the sprocket 75. The waste material flies to the side and falls into the receiving groove, and is extracted from the receiving groove by the collecting device 8 through vacuum suction, ensuring that the first receiving groove and the second receiving groove are kept clean. In order to avoid the influence of vibration on the die-cutting machine body 1, a shock-absorbing cushion layer is also provided on the top of the left side of the workbench 9 to reduce the vibration generated when the waste cleaning module 7 contacts with the material. After the waste cleaning is completed, the second pneumatic telescopic rod 321 drives the limit plate 322 to rise again, releasing the fixation of the stacked material. At this time, the material is already a finished product and can be transported to the next process by manual or machine.
