[0049] With the development of processing manufacturing industry and automation assembly line operation, automation equipment has become an indispensable part in production. Laser marking cutting is also a commonly used processing equipment in society, and the traditional equipment is usually used for mold stamping processing on fruit and vegetable box. However, the traditional stamping processing will have the problem of frequent replacement of mold, and the laser hole cutting mode can well solve the above problems. The laser hole cutting equipment will produce smoke and production waste in the process of punching, the traditional waste collecting device has poor collecting capacity, and there is waste falling out and it is difficult to effectively collect smoke and waste at the same time, the present application provides a kind of flexible exhaust structure for solving the above problems.

[0050] The present application provides an adsorption exhaust structure and a carton punching equipment to solve the above problems.

[0051] Please refer to Figures 1 to 3In an embodiment of the utility model, propose a kind of adsorption waste discharge structure 100, the adsorption waste discharge structure 100 is mainly used in waste treatment in laser drilling operation.Different from conventional waste collection cleaning structure, the related structure in the embodiment of the utility model, waste collection requirement in laser drilling structure can be well adapted.Laser is easily produced smoke particle when processing some paper or plastic product.The produced smoke particle is not only pungent and offensive, simultaneously, there is certain harm to human body, the related structure in the embodiment of the utility model can be classified and handled to waste gas and waste material generated in the process of laser processing in the process of use, to effectively improve the collection effect of waste generated in the process of laser drilling production.Specifically, the adsorption waste discharge structure 100 includes chassis 1, hopper structure 2 and waste discharge device, the hopper structure 2 is installed on the chassis 1, the hopper structure 2 includes shell 211 and inner material guiding portion 212, the upper end of the shell 211 is equipped with feeding portion, the inner material guiding portion 212 is arranged in the shell 211 corresponding to the feeding portion, to form double-layer waste discharge structure, and the smoke inlet channel 2121 is formed between the shell 211 and the inner material guiding portion 212, the waste discharge device is installed on the hopper structure 2, for collecting waste gas and promoting waste material from the inner material guiding portion 212.

[0052] In the above embodiment, the hopper portion 21 is provided as a double-layer structure, which includes a shell 211 and an inner material guiding portion 212, and the inner material guiding portion 212 is arranged inside the shell 211. The inner material guiding portion 212 includes two ports arranged in the up-down direction, wherein the upper port is an inlet port, and the lower port is a discharge port. The upper port is larger than the lower port, which facilitates the collection and centralized discharge of waste materials. The feeding portion is arranged on the upper end surface of the shell 211, and the opening size of the feeding portion is smaller than that of the upper port of the inner material guiding portion 212. Therefore, to a certain extent, the waste materials can be collected, and under the action of the waste discharge device, the waste materials discharged into the inner material guiding portion 212 can be effectively discharged from the end portion thereof. For the smoke generated during production, the waste discharge device is connected to the smoke inlet channel 2121 during actual processing and production, and negative pressure is generated in the smoke inlet channel 2121, so that the generated smoke can enter the smoke inlet channel 2121 and be effectively collected and treated under the action of the waste discharge device.

[0053] Traditional waste discharge structure mostly has only solid waste collection function. In actual production process, workers wear masks to carry out production operation. This operation method cannot effectively ensure the cleanliness of the production environment and has certain safety hazards. Some waste collection devices set the solid waste collection structure and the flue gas waste collection structure as relatively independent treatment equipment. This way, the investment cost is large and it is difficult to integrate. In actual use, the occupied space is large, which is not conducive to improve the convenience of production, and the collection effect of waste gas is also very small.

[0054] When collecting and processing smoke, in order to avoid the waste generated by processing entering the smoke inlet channel 2121 along with the airflow, thereby affecting the actual collection effect of the smoke. In actual setting, a covering structure is arranged on the inside of the shell 211 and corresponds to the upper position of the smoke inlet channel 2121. In an embodiment of the present application, a perforated plate 2122 is arranged on the inside of the shell 211, and the perforated plate 2122 is at least partially arranged above the smoke inlet channel 2121 to define a smoke inlet area above the smoke inlet channel 2121. In the production process, the waste discharge device generates negative pressure in the smoke inlet channel 2121, and the solid waste generated in the cutting process is likely to fall into the smoke inlet channel 2121. The arrangement of the perforated plate 2122 can partially cover the upper part of the smoke inlet channel 2121, thereby preventing the solid waste from entering the smoke inlet channel 2121 as much as possible. And the arrangement of the perforated plate 2122 can define a certain smoke inlet area at the opening position of the smoke inlet channel 2121, which can cooperate with the waste discharge device to achieve efficient waste discharge effect.

[0055] It is conceived that the smoke inlet area is related to the size of the smoke outlet 2111a, if the smoke inlet area is too large and the smoke outlet 2111a is too small, the smoke cannot be effectively adsorbed and collected; if the smoke inlet area is too small and the smoke outlet 2111a is too large, the power of the waste discharge device may be excessive during operation, which is not conducive to the saving of production materials. Therefore, in an embodiment of the present application, the shell 211 is provided with two smoke outlets 2111a corresponding to the position of the smoke inlet passage 2121, and the ratio of the area of a single smoke outlet 2111a to the smoke inlet area is 1:3; the waste discharge device comprises a negative pressure device, one end of the negative pressure device is connected to the two smoke outlets 2111a. During actual operation, the negative pressure device provides negative pressure at the smoke outlet 2111a, so that the smoke is sucked into the smoke inlet passage 2121 through the through hole structure on the porous plate 2122. And in this embodiment, the ratio of the area of a single smoke outlet 2111a to the smoke inlet area is 1:3, and during actual smoke discharge, the two negative pressure devices work simultaneously to achieve better suction effect of the smoke.

[0056] In addition, it should be noted that the ratio of the area of a single smoke outlet 2111a to the smoke inlet area in the above embodiment is 1:3, which is a more preferred embodiment selected after continuous debugging of the present application. In actual production process, if high-power negative pressure equipment is used, better adsorption and collection effect can also be achieved when the smoke inlet area is large. Therefore, the actual ratio size may need to be determined in combination with the production parameters of the actual negative pressure equipment.

[0057] In an embodiment of the present application, a waste discharge pipe 22 is further arranged below the funnel structure 2. Specifically, the adsorption waste discharge structure 100 further comprises a waste discharge pipe 22, the waste discharge pipe 22 is arranged in the horizontal direction, and a connecting port 221 is arranged on the peripheral wall of the waste discharge pipe 22, and the lower end of the inner material guiding part 212 is connected with the connecting port 221. The waste discharge pipe 22 is arranged in the horizontal direction, which can minimize the overall height of the entire structure, and make the structure of the entire adsorption waste discharge structure 100 more compact. The connecting port 221 is arranged on the peripheral wall of the waste discharge pipe 22, and the connecting port 221 and the lower end of the inner material guiding part 212 are connected through a material guiding cylinder 3. The upper end opening of the material guiding cylinder 3 is larger than the lower end opening, which is convenient for collecting waste. The two end portions of the material guiding cylinder 3 are detachably installed by bolts, which can be timely treated when blockage occurs.

[0058] The blowing device (not shown in the figure) in the waste discharge device is connected to one end of the waste discharge pipe 22, and can increase the pressure in the waste discharge pipe 22 when working, thereby facilitating the discharge of the material inside the waste discharge pipe 22 from the other end of the waste discharge pipe 22. In this process, since the opening at the lower end of the guide cylinder 3 is relatively small, it basically does not affect the discharge of the waste, or it is feasible to stop the discharge of the waste.

[0059] In addition, in order to increase the efficiency of the discharge of the waste, the inner guide part 212 is adaptively provided with two or more, and the corresponding connecting structure is also provided with a corresponding number, and then the size of the opening part 212a is expanded, thereby effectively increasing the receiving area of the waste and accelerating the discharge of the waste. The specific number of the inner guide part 212 can be set according to the actual production needs.

[0060] In order to improve the collection effect of the waste and avoid the discharge of the waste to the external production environment, in one embodiment of the present application, one end of the adsorption waste discharge structure 100 is arranged as close to the discharging area as possible. Specifically, the adsorption waste discharge structure 100 further comprises an adjusting structure 4, the adjusting structure 4 comprises a height adjusting structure 41 and an upper surrounding plate structure 42, a discharging channel 5 is formed in the inner side of the upper surrounding plate structure 42, the cross-sectional area of the discharging channel 5 is adjustable, the feeding part is connected to one end of the discharging channel 5 downward, the height adjusting structure 41 is arranged on the bottom frame 1, and the output end of the height adjusting structure 41 is connected to one end of the upper surrounding plate structure 42, so as to adjust the vertical height of the upper surrounding plate structure 42.

[0061] In the above embodiment, the relevant structure has the characteristics of flexible adjustment, which can be adjusted to the position close to the processed product as much as possible according to the actual specifications and specific positions of the processed product, so as to further improve the collection and discharge effect of the waste, and because of the flexibility of the adjustment, the limitation of the waste discharge position of the processing equipment is smaller, which is more conducive to the installation of the processing equipment. Specifically, the upper surrounding plate structure 42 in the adjusting structure 4 is a four-sided surrounding structure, and the inner side of the surrounding plate structure is formed with a discharging channel 5. The lower end of the discharging channel 5 corresponds to the feeding part, and the cross-sectional area of the discharging channel 5 formed in the inner side of the surrounding plate structure is adjustable. Such arrangement can allow the upper surrounding plate structure 42 to be sleeved on the lower end of the processed material, and at this time, if the bottom of the material is punched, the cut waste can directly fall into the hopper structure 2 through the discharging channel 5, and the waste will not fly out from the end of the processed material, which is more conducive to the collection of waste. Especially when cutting and punching the paper box structure or the plastic box structure, the above structure can achieve good waste collection effect. And in the actual adjustment process, the output end of the height adjusting structure 41 is connected to one end of the upper surrounding plate structure 42, which can drive the upper surrounding plate structure 42 to be sleeved on the outer periphery of the lower end of the processed material, so as to realize automatic adjustment, and the production efficiency can be further improved.

[0062] Among them, the feeding part is connected to the lower end of the discharging channel 5. It is conceivable that the height of the lower end of the discharging channel 5 should be adjusted according to the actual situation of the processed material, so a length-variable connecting structure should be provided between the two, such as a corrugated pipe or a cloth dust cover, which can be selected and used according to the actual production material.

[0063] The upper surrounding plate structure 42 comprises a lower bottom plate 421, and a discharging hole is arranged at the middle position of the lower bottom plate 421, and the cross-sectional area of the discharging hole is greater than the maximum cross-sectional area of the discharging channel 5. Two enclosing parts 422 are arranged on the upper end surface of the bottom plate 421, and the horizontal ends of the two enclosing parts 422 are provided with openings, and the two opening ends are slidably connected in the horizontal first direction, so as to form the discharging channel 5 between the two enclosing parts 422, and the cross section of the discharging channel 5 in the first direction is adjustable. In order to enable the side walls of the upper surrounding plate structure 42 to better adhere to the outer wall of the discharging end of the processed material, in the embodiment, the opening of the enclosing part 422 is also arranged to be adjustable in size. Specifically, the enclosing part 422 comprises a first surrounding plate 4221 arranged in the second direction, and the first surrounding plate 4221 is slidably installed on the bottom plate 421 in the first direction, wherein the second direction is perpendicular to the first direction in the horizontal plane. Two second surrounding plates 4222 are arranged on the first surrounding plate 4221 in the second direction, and the end portions of the two second surrounding plates 4222 are slidably installed on the first surrounding plate 4221 in the second direction. The end portions of the two second surrounding plates 4222 corresponding to the two first surrounding plates 4221 are slidably connected. After the above structure is installed, the upper surrounding plate structure 42 shown in the figure is formed. In the specific adjustment process, the two second surrounding plates 4222 in the two enclosing parts 422 slide relative to each other to realize the cross-sectional adjustment of the discharging channel 5 in the first direction, and the two second surrounding plates 4222 connected to each other move towards each other between the two first surrounding plates 4221, so as to realize the cross-sectional adjustment of the discharging channel 5 in the second direction. Therefore, according to the actual size of the discharging end of the processed material, the entire upper surrounding plate structure 42 can be sleeved on the outer side of the discharging end of the processed material through the above adjustment mode. It is conceivable that the above disclosed sliding installation connection mode can be provided as a convex ridge and a sliding groove cooperation or a long groove and a bolt cooperation structure, and the corresponding sliding installation structure can be selected according to the actual situation. The above sliding installation structures are common sliding cooperation structures and are easy to realize, and will not be described here.

[0064] In actual processing, first, the material is placed in the processing position, the actual size of the discharging channel 5 can be coarsely adjusted according to the actual size of the discharging end of the processed material, then the upper surrounding plate structure 42 is raised by the height adjustment structure 41 to surround the outer side of the end portion of the processed material, and then the first surrounding plate 4221 and the second surrounding plate 4222 are attached to the outer side of the end portion of the processed material through the above adjustment mode.

[0065] The height adjusting structure 41 specifically comprises a driving guide 412. The guide 412 adopts a shaft cylinder guiding mode. Specifically, a support plate portion is arranged below the bottom plate 421, a plurality of vertical cylinder portions 4121 are arranged on the bottom frame 1, a guide rod portion 4122 is matched and arranged in the inner hole of each cylinder portion 4121, and the upper end of the guide rod portion 4122 is connected with the support plate portion on the lower end surface of the bottom plate 421. The driving member 411 is arranged on the bottom frame 1, and one end of the driving member 411 is connected with the support plate portion on the lower end surface of the bottom plate 421. When the driving member 411 works, the upper surrounding plate structure 42 can move in the vertical direction, so that the upper surrounding plate is adjusted to a suitable vertical height. In this process, the plurality of guide rod portions 4122 slide in the plurality of cylinder portions 4121, so as to guide the movement and further improve the stability of the lifting process of the whole upper surrounding plate structure 42.

[0066] It is conceived that the driving member 411 is a linear driving structure. There are many choices of the linear driving structure, and a single linear driving structure such as a cylinder or a push rod can be selected as the driving member 411 according to the actual situation. Alternatively, a motor member is adopted as the driving member 411, and the upper surrounding plate structure 42 is driven to move in the vertical direction through a transmission structure. For example, a screw rod and a motor are connected, the bottom plate 421 is matched with the screw rod, and the screw rod is driven to rotate by the motor member, so that the bottom plate 421 moves in the vertical direction. Alternatively, a motor is matched with a gear and a rack structure as a driving combination. In the actual installation process, one end of the rack is arranged on the lower end surface of the bottom plate 421, and the gear is arranged on the output shaft of the motor and is engaged with the rack. At this time, when the motor works, the bottom plate 421 can be driven to move in the vertical direction through the cooperation of the gear and the rack, so as to adjust the vertical height of the upper surrounding plate structure 42. The structures of the driving member 411 disclosed above are only part of the linear driving structures, and can be selected and arranged according to the actual situation of the production materials.

[0067] In addition, the shell 211 comprises a side wall portion 2111 and a cover plate portion 2112, and the inner material guiding portion 212 is arranged on the inner side of the side wall portion 2111. The cover plate portion 2112 is arranged above the side wall portion 2111, the cover plate portion 2112 is provided with an opening portion 2112a, the opening portion 2112a comprises the above-mentioned feeding portion, and the opening portion 2112a is mainly arranged corresponding to the upper end of the inner material guiding portion 212. The opening portion 2112a is arranged above the multi-hole plate 2122 and has a certain gap distance therebetween, which can prevent waste materials from entering the smoke inlet channel 2121 without affecting the collection of smoke.
