Description

Technical Field

[0001] This invention relates to a foam board production equipment, and more particularly to a fully automated punching and forming intelligent production line for foam boards. Background Technology

[0002] EVA material (also known as foam) is a commonly used material, and processed products are widely used in various fields such as daily life and production. For example, it can be used as shockproof and cushioning outer packaging for fragile canned agricultural products (such as honey, canned fruit, etc.), protective packaging for electronic products (such as mobile phones, tablets, etc.), and sporting goods (protective gear, yoga mats, etc.).

[0003] Generally, EVA material is made into raw materials for sheets and supplied to downstream processing plants, which then process the sheets into finished products. The processing involves manually transporting stacked sheets one by one to a punching machine. After punching, the sheets are automatically conveyed to a waste removal machine, which ejects the punched modules from the sheets to form finished products, separating the finished products from the waste. The collected products are then transported to the packaging area for packaging. This process is not highly automated, requiring manual transport of the sheets to the punching machine, which is both labor-intensive and inefficient. Therefore, this application modifies the existing elevator and combines it with the existing conveyor platform, punching machine, and waste removal machine to form an intelligent automated production line, thereby solving the above problems and improving production efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a fully automated die-cutting intelligent production line for foamed boards.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A fully automated intelligent production line for foamed board punching and forming includes a hoist, a transfer platform, a punching machine, and a waste removal machine. The hoist includes a lifting frame, a lifting seat mounted on the hoist, and a lifting drive mechanism that drives the lifting seat to rise and fall. A stack of boards is piled on the lifting seat. The hoist features a flexible suction cup conveying mechanism, which includes a suction cup frame and a suction cup moving mechanism that moves the suction cup frame. The suction cup frame has an adaptive suction cup component, an adaptive connecting plate, and an elastic support structure that supports the adaptive connecting plate. The adaptive connecting plate is rotatably connected to the suction cup frame. The adaptive suction cup component is mounted on the adaptive connecting plate. The suction cup moving mechanism can move the suction cup frame above the board stack and, through the adaptive suction cup component, adsorb the boards and convey them to the transfer platform. The transfer platform then conveys the boards to the punching machine and the waste removal machine.

[0007] The suction cup holder includes a frame rod, and a plurality of support plates are provided on one side of the frame rod. The support plates are provided with fixed suction cup components, and the adaptive connecting plate is rotatably connected to the support plates.

[0008] The elastic support structure includes a spring, one end of which abuts against the suction cup holder and the other end of which abuts against the adaptive connecting plate.

[0009] The elastic support structure also includes a sliding hole on the suction cup holder and a guide shaft that mates with the sliding hole. The guide shaft is fixed to the adaptive connecting plate, and the spring is disposed on the guide shaft.

[0010] The adaptive connecting plate is provided with a connecting hole, and the guide shaft is provided with a first limiting piece and a second limiting piece. The guide shaft passes through the connecting hole and clamps the adaptive connecting plate through the first limiting piece and the second limiting piece. The other end of the spring abuts against the first limiting piece.

[0011] The waste removal machine includes a stamping table and a die or punch rod disposed below the stamping table, as well as a waste removal frame and a conveyor table. The waste removal frame is provided with a plate lifting mechanism for lifting the plate from the conveyor table. The stamping table can drive the die or punch rod to stamp the lifted plate, thereby punching out the module embedded in the plate onto the conveyor table.

[0012] The plate lifting mechanism includes a needle, a needle driving mechanism that drives the needle to insert into or pull out of the plate, and a needle lifting mechanism that drives the needle to rise and fall.

[0013] The needle lifting mechanism includes a needle lifting drive unit mounted on a waste removal frame, a needle chain transmission mechanism connected to the needle lifting drive unit, a needle screw assembly connected to the needle chain transmission mechanism, and a needle lifting frame connected to and driven by the needle screw assembly to lift and lower. The needle drive mechanism and a needle are mounted on the needle lifting frame.

[0014] The needle lifting frame is provided with a needle mounting plate. The needle driving mechanism includes a needle cylinder one fixed on the needle mounting plate, and a needle one connected to the needle cylinder one. The needle driving mechanism also includes a needle cylinder two fixed on the needle mounting plate, and a needle cylinder two connected to the needle two.

[0015] The needle-punching lifting frame is equipped with a spacing adjustment plate, which is equipped with a spacing adjustment motor, an adjustment chain transmission mechanism connected to the spacing adjustment motor, and an adjustment screw assembly. The needle-punching mounting plate is connected to and moves with the adjustment screw assembly. The spacing adjustment plate is equipped with a guide linear bearing and a guide rod that cooperates with the guide linear shaft. The guide rod is connected to the needle-punching mounting plate.

[0016] The beneficial effects of this invention are: by adding a flexible suction cup conveying mechanism to the lifting frame, the invention connects the lifting machine, the transfer table, the punching machine and the waste discharge machine into an automated production line, which greatly reduces the participation of manual labor, is more efficient, and also greatly reduces the labor intensity of workers.

The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0036] Reference Figure 1 , Figure 2This invention discloses a fully automated intelligent production line for punching and forming foamed boards, including a hoist 100, a transfer table 200, a punching machine 300, and a waste discharge machine 400. The hoist 100 includes a lifting frame 101, a lifting seat mounted on the lifting frame 101, and a lifting drive mechanism for raising and lowering the lifting seat. A stack of boards is piled on the lifting seat, and the board stack is transported to the lifting seat by a forklift. The lifting frame 101 is equipped with a flexible suction cup conveying mechanism 500, which includes a suction cup frame 1 and a mechanism for moving the suction cup frame 1. The suction cup moving mechanism includes an adaptive suction cup component 2, an adaptive connecting plate 3, and an elastic support structure supporting the adaptive connecting plate 3 on the suction cup frame 1. The adaptive connecting plate 3 is rotatably connected to the suction cup frame 1. The adaptive suction cup component 2 is disposed on the adaptive connecting plate 3. The suction cup moving mechanism can drive the suction cup frame 1 to move above the stack of boards and adsorb the boards through the adaptive suction cup component 2, and transport the boards 6 to the transfer table 200. The transfer table 200 transports the boards to the punching machine 300 for punching, and after punching, the boards are sent to the waste discharge machine 400.

[0037] The suction cup holder 1 of this application is equipped with an adaptive suction cup component 2 and a fixed suction cup component 5. The adaptive suction cup component 2 and the fixed suction cup component 5 have the same structure and are existing technologies, so the specific structure will not be described in detail. The adaptive suction cup component 2 and the fixed suction cup component 5 are arranged in two rows and are parallel. When adsorbing the board 6, which is mainly EVA board, the fixed suction cup component 5 is closer to the edge of the board 6, while the adaptive suction cup component 2 is farther from the edge of the board 6. In this way, the rest of the board 6 is suspended. The gravity generated by the rest of the board 6 will cause the board 6 to start to bend and deform at the adsorption point of the adaptive suction cup component 2. The bending and deformation will cause the surface of the board 6 to be uneven with the suction cup of the adaptive suction cup component 2, which will easily cause it to detach from the suction cup. Therefore, through the adjustment of the adaptive connecting plate 3, the suction cup can be tilted with the bending and deformation of the board 6, so as to ensure that the suction cup in the adaptive suction cup component 2 is parallel to the board 6 as much as possible, thereby greatly reducing the risk of the board 6 detaching from the suction cup. This equipment is used to produce outer packaging for agricultural products. It is not only simple in structure and low in cost, but also automated in production, which greatly improves the intelligence level of packaging product manufacturing.

[0038] The addition of a flexible suction cup conveying mechanism 500 to the elevator 100 makes it particularly suitable for conveying EVA sheets. This allows it to work in conjunction with the transfer table 200 to achieve the initial conveying of EVA sheets and enable automatic feeding of the punching machine 300 without the need for manual handling.

[0039] The principle of the above mechanism is as follows: Sheets 6 are stacked on the elevator 100 to form a sheet pile. The suction cup moving mechanism moves the suction cup frame above the sheet pile. Then, the suction cup moving mechanism lowers the suction cup frame so that the adaptive suction cup 2 and the fixed suction cup 5 adhere to the top sheet 6 of the sheet pile. The suction cup moving mechanism then raises the suction cup frame and moves in the opposite direction. After the top sheet 6 is grasped, the elevator 100 raises the lifting seat via the lifting drive mechanism, raising the sheet pile by the thickness of one sheet 6, thus facilitating accurate grasping next time. The mechanism moves the sheet material 6 to the top of the transfer platform 200. Then, the suction cup moving mechanism drives the suction cup frame to descend, causing the adaptive suction cup component 2 and the fixed suction cup component 5 to release the sheet material 6, so that the sheet material 6 falls onto the transfer platform 200. The transfer platform 200 then conveys the sheet material to the punching machine 300. The inlet and outlet of the punching machine 300 are equipped with several powered conveying rollers. Therefore, the sheet material 6 fed into the punching machine 300 can be conveyed to the punching position by the conveying rollers. After punching, the sheet material 6 is conveyed to the waste discharge machine 400 by the corresponding conveying rollers to discharge waste, and finally the product is formed.

[0040] like Figures 3 to 5 As shown, the suction cup holder 1 includes a frame rod 7, with several support plates 8 on one side of the frame rod 7. The fixed suction cup component 5 is disposed on the support plate 8, and the adaptive connecting plate 3 is rotatably connected to the support plate 8. In this way, the adaptive suction cup component 2 and the fixed suction cup are arranged parallel to the frame rod 7, forming a matrix-like multi-point adsorption, thereby making the adsorption force more uniform. Preferably, it also includes a hinge 9, and the adaptive connecting plate 3 is rotatably connected to the support plate 8 through the hinge 9. The hinge 9 is not only a mature hardware component, but also easy to purchase and low in cost.

[0041] like Figure 5 As shown, the elastic support structure 4 includes a spring 10. One end of the spring 10 abuts against the suction cup frame 1 and the other end abuts against the adaptive connecting plate 3. In this way, when the adaptive connecting plate 3 is not adsorbing the plate 6, the adaptive connecting plate 3 can rotate upward to reset, thereby avoiding interference between the adaptive connecting plate 3 and the plate 6 when adsorbing the plate 6.

[0042] Specifically, the elastic support structure 4 also includes a sliding hole on the suction cup holder 1 and a guide shaft 11 that mates with the sliding hole. The guide shaft 11 is fixed to the adaptive connecting plate 3. The spring 10 is disposed on the guide shaft 11. The guide shaft 11 ensures that the spring 10 does not deviate when it contracts or extends. Specifically, the adaptive connecting plate 3 is provided with a connecting hole. A first limiting piece 12 and a second limiting piece 13 are fixed on the guide shaft 11. The guide shaft 11 passes through the connecting hole and clamps the adaptive connecting plate 3 through the first limiting piece 12 and the second limiting piece 13. The other end of the spring 10 abuts against the first limiting piece 12. The above structure is simple. The second limiting piece 13 is fixed to the guide shaft 11 by screws.

[0043] like Figure 3 As shown, the suction cup holder 1 of this application needs to be raised and lowered. Therefore, the suction cup moving mechanism includes a sliding plate 14 and a lead screw assembly 15 and a lifting drive motor 16 disposed on the sliding plate 14. The lifting drive motor 16 is connected to the lead screw assembly 15 through a belt transmission mechanism. The suction cup holder 1 is connected to the lead screw assembly 15 and is raised and lowered. It also includes a sliding shaft 17. One end of the sliding shaft 17 is fixed to the suction cup holder 1. The sliding plate 14 is provided with a shaft hole that mates with the sliding shaft 17. Therefore, the lifting drive motor 16 drives the suction cup holder 1 to rise and fall along the axial direction of the sliding shaft 17 through the belt transmission mechanism 18 and the lead screw assembly 15. The belt transmission mechanism 18 and the lead screw assembly 15 are conventional transmission designs, so their specific structures are not described in detail.

[0044] like Figure 3 As shown, the suction cup moving mechanism also includes a linear guide rail assembly 19, a belt drive mechanism 20 disposed opposite to it, a translation drive motor 21, and a translation transmission shaft 22 connected to the translation drive motor 21. The linear guide rail assembly 19 and the translation drive motor 21 are both disposed on the lifting frame 101 of the lifting machine 100. The belt drive mechanism 20 is connected to the translation transmission shaft 22 and disposed on the lifting frame 101. The slide plate 14 is connected to the belt drive mechanism 20 and thus moves. The slide plate 14 is connected to the linear guide rail assembly 19.

[0045] As a further preferred structure, in order to further improve the efficiency of the entire production line, the applicant has also made improvements to the waste discharge machine 400.

[0046] A typical waste removal machine (model 400) generally consists of two parts: an upper stamping table with dies or punches, and a lower template. The cut sheet metal is conveyed to the lower template. The positions of the dies or punches and the specifications of the lower template are determined according to the shape of the product and its position on the sheet metal. When the stamping table drives the dies or punches to impact the module, the module is punched out from the corresponding holes in the sheet metal and the lower template. The remaining waste material is supported by the lower template and left on it for manual collection.

[0047] After changing products, the above-mentioned waste discharge machine 400 not only needs to readjust the position of the punch rod, but also needs to replace the punch die with one that corresponds to the new product. Furthermore, the bottom template below needs to be redesigned and replaced according to the shape of the product and its position on the sheet metal. This results in a variety of bottom template specifications and a long time to replace the bottom template, thereby reducing production efficiency. After the product is produced, the bottom template can only be destroyed, resulting in waste. Therefore, this application has made improvements to the waste discharge machine 400.

[0048] Reference Figures 6 to 11The waste removal machine 400 includes a waste removal frame 23 and a conveyor table 24. The conveyor table 24 is disposed on the waste removal frame 23. The waste removal frame 23 is provided with a plate lifting mechanism for lifting the plate from the conveyor table 24. The waste removal frame 23 also includes a stamping table 25 and a stamping table lifting drive mechanism 26 for driving the stamping table 25 to rise and fall. A stamping die 27 is fixed below the stamping table 25. The stamping die 27 is generally made of wood, making it easy to manufacture and low in cost. The stamping die 27 is matched according to the shape and position of the product. All of the above are the same as existing technologies and previous structures, and therefore will not be described in detail in this application.

[0049] After the punched sheet 6 is conveyed onto the conveyor table 24, the sheet lifting mechanism lifts the sheet 6, creating space between the sheet 6 and the conveyor table 24 for the module to fall. Therefore, when the stamping table 25, carrying the die 27, punches down, it can punch the module onto the conveyor table 24. After the module is conveyed, the sheet lifting mechanism can release the remaining waste material, allowing it to fall onto the conveyor table 24. Thus, the conveyor table 24 can simultaneously convey the fallen module and the remaining waste material to the collection point. Compared to the previous waste discharge machine 400, this application uses a sheet 6 lifting method, thus eliminating the need for a bottom template. The lower conveyor table 24 can directly convey both the module and the remaining waste material, thereby improving production efficiency, reducing waste, and making production more environmentally friendly.

[0050] The plate lifting mechanism includes a needle 28, a needle driving mechanism that drives the needle 28 to insert into or pull out the plate 6, and a needle lifting mechanism that drives the needle 28 to rise and fall. Because the plate 6 of this application is a porous material with a certain degree of softness and has various thicknesses and widths, if a clamping method is used, the plate 6 is easy to be twisted and deformed, and the clamping structure is complicated.

[0051] The needle lifting mechanism includes a needle lifting drive unit mounted on the waste removal frame 23, a needle chain drive mechanism 29 connected to the needle lifting drive unit, a needle screw assembly 30 connected to the needle chain drive mechanism 29, and a needle lifting frame 31 connected to and driven by the needle screw assembly 30. The needle drive mechanism and the needle 28 are mounted on the needle lifting frame 31. The needle lifting drive unit uses a common motor, and the needle chain drive mechanism 29 and the needle screw assembly 30 are also conventional chain drive structures, so details are not provided. Through the above structure... When the needle 28 pierces into both sides of the plate 6, the needle lifting drive unit works, driving the needle screw assembly 30 through the needle chain transmission mechanism 29, and driving the needle lifting frame 31 to rise and fall through the needle screw assembly 30, thereby realizing the lifting and falling of the needle 28 and the plate 6. The above structure does not need to consider the thickness of the plate 6, and the edge of the plate 6 will not be deformed after the needle 28 pierces in. Of course, the relative arrangement of the needle 28 in this application, as well as the needle lifting drive unit, the needle chain transmission mechanism 29, the needle screw assembly 30, and the needle lifting frame 31, are all correspondingly and relatively arranged.

[0052] As a specific structure, for ease of installation, a needle mounting plate 32 is fixed on the needle lifting frame 31. The needle driving mechanism includes a needle cylinder 33 fixed on the needle mounting plate 32. The needle 28 is connected to the needle cylinder 33. Therefore, the needle cylinder 33 can directly push the needle 28 to move horizontally and pierce the side of the plate 6. Of course, the needle 28 is fixed on the connecting plate, and the connecting plate is fixed to the piston rod of the needle cylinder 33.

[0053] As a preferred structure, the needle-punching driving mechanism further includes a needle-punching cylinder 34 fixed on the needle-punching mounting plate 32. The needle-punching cylinder 34 is connected to a needle 35. The connection between the needle 35 and the needle-punching cylinder 34 is similar to the connection between the needle 28 and the needle-punching cylinder 33. The needle 35 is set vertically relative to the needle 28. Therefore, the needle 35 descends vertically and pierces the edge of the upper surface of the plate 6. Because the plate 6 has a certain degree of flexibility and a certain width, when the needle 28 lifts the plate 6, the plate 6 will bend significantly. Moreover, the downward punching force of the die 27 is also considerable. This can easily cause the plate 6 to detach from the needle 28. Therefore, by restricting the vertical insertion of the needle 35, the needle 35 and the needle 28 intersect to form a three-dimensional fixing structure, thereby effectively preventing the plate 6 from easily falling off when the die 27 punches downward.

[0054] As a preferred structure, the needle mounting plate 32 is provided with an extension plate 36 and a pressure plate 37 fixed to the extension plate 36. Both the extension plate 36 and the pressure plate 37 are provided with needle guide holes. The first needle 28 and the second needle 35 can pass through the corresponding needle guide holes 38. After the plate 6 is located on the conveying table 24, the needle lifting drive unit will drive the needle lifting frame 31 and the needle mounting plate 32 to descend through the needle chain transmission mechanism 29, so that the pressure plate 37 can press down on the edge of the plate 6, which facilitates the subsequent insertion of the needles. The first needle 28 and the second needle 35 can play a supporting role through the corresponding needle guide holes 38.

[0055] like Figure 8 As shown, the needle-punching lifting frame 31 is equipped with a spacing adjustment plate 39. The spacing adjustment plate 39 is equipped with a spacing adjustment motor 40, an adjustment chain transmission mechanism 41 connected to the spacing adjustment motor 40, and an adjustment screw assembly 42. The needle-punching mounting plate 32 is connected to the adjustment screw assembly 42 and moves accordingly. The spacing adjustment plate 39 is equipped with a guide linear bearing and a guide rod 43 that cooperates with the guide linear shaft. The guide rod 43 is connected to the needle-punching mounting plate 32. The spacing adjustment motor 40 is a common motor. The adjustment chain transmission mechanism 41 and the adjustment screw assembly 42 are also conventional belt drive structures, so they will not be described in detail.

[0056] Therefore, through the above structure, we can adjust the distance between the needle mounting plate 32 and the edge of the plate 6, so as to adapt to plates 6 of different widths. Moreover, the needle mounting plate 32 is equipped with a baffle cylinder 44 and a baffle plate 45 connected to the baffle cylinder 44. Through the combination of the baffle cylinder 44 and the baffle plate 45, we can also achieve the purpose of positioning and correcting the plate 6. When the plate 6 is on the conveyor table 24, the baffle plate 45 is pushed out by the baffle cylinder 44. Then, the spacing adjustment motor 40 drives the needle mounting plate 32 to move closer to the edge of the plate 6 through the adjustment chain transmission mechanism 41 until the baffle plate 45 abuts against the two sides of the plate 6, thereby achieving the positioning and correction of the plate 6. After positioning, the baffle plate 45 is pulled back by the baffle cylinder 44. Then, the needle lifting drive unit will drive the needle lifting frame 31 and the needle mounting plate 32 to descend through the needle chain transmission mechanism 29, so that the pressure plate 37 can press the edge of the plate 6, which is convenient for the subsequent insertion of the needle.

[0057] like Figure 6As shown, the conveying platform 24 includes a direct conveying platform 46 and a sorting platform 47. The sorting platform 47 is arranged perpendicularly to the direct conveying platform 46, and the material conveyed by the direct conveying platform 46 can fall onto the sorting platform 47. Both ends of the sorting platform 47 are material outlets. The direct conveying platform 46 is located below the stamping platform 25, while the sorting platform 47 is located to the side of the stamping platform 25. In this way, the punched-out modules and the remaining waste can fall onto the direct conveying platform 46 and then be conveyed to the sorting platform 47. If it is a module, the sorting platform 47 will convey it to one side for collection, and if it is waste, the sorting platform 47 will convey it to the other side for collection, which facilitates the classification and collection of materials.

[0058] Specifically, both the direct conveyor 46 and the sorting station 47 include a conveyor motor 48, two parallel conveyor rollers, a conveyor chain drive mechanism 49 connected to the conveyor motor 48, and a conveyor belt 50 mounted on the conveyor rollers. The conveyor chain drive mechanism 49 is connected to the corresponding conveyor rollers. Therefore, through the combined action of the conveyor motor 48, the conveyor chain drive mechanism 49, and the two conveyor rollers, the conveyor belt 50 is rotated, thereby realizing the conveying of modules and remaining waste materials. The conveyor motor 48 is a common motor, and the conveyor chain drive mechanism 49 and the conveyor rollers are conventional transmission structure combinations, so they will not be described in detail. The structure and principle of the transfer station 200 are the same as those of the direct conveyor 46 and the sorting station 47, so the structure of the transfer station 200 is not described in detail.

[0059] The working process of this application is briefly described as follows: When the sheet metal 6 is delivered from the punching machine 300 to the conveyor table 24, the baffle plate 45 is extended by the baffle cylinder 44. Then, the spacing adjustment motor 40 drives the needle-punching mounting plate 32 to move closer to the edge of the sheet metal 6 through the adjusting chain transmission mechanism 41, until the baffle plate 45 abuts against the two sides of the sheet metal 6, thereby achieving the positioning and correction of the sheet metal 6. After positioning, the baffle plate 45 is pulled back by the baffle cylinder 44. Then, the needle-punching lifting drive unit drives the needle-punching lifting frame 31 and the needle-punching mounting plate 32 to descend through the needle-punching chain transmission mechanism 29, so that the pressure plate 37 can press the edge of the sheet metal 6. Then, the needle-punching cylinder 1 33 and the needle-punching cylinder 2 34 start working, respectively driving the needle 1 28 and the needle 2 35 to pierce the sheet metal 6, thereby fixing the sheet metal 6. Then, the needle-punching lifting drive unit drives the needle-punching lifting frame 31 and the needle-punching mounting plate 32 through the needle-punching chain transmission mechanism 29. Plate 32 rises and resets, creating a gap between plate 6 and conveyor table 24. Then, the punching platform lifting drive mechanism 26 drives the punching platform 25 and punching die 27 to punch downwards, causing the module to fall onto the direct delivery platform 46. The punching platform 25 and punching die 27 reset, and the module is then conveyed to the sorting platform 47 via the direct delivery platform 46. The sorting platform 47 will then transport it to one side for collection. Then, the second needle cylinder 34 starts to move, causing the second needle 35 to retract and be pulled out of plate 6. Then, the first needle cylinder 33 starts to move, causing the first needle 28 to retract and be pulled out of plate 6. Plate 6 will then fall onto the direct delivery platform 46 and be conveyed to the sorting platform 47 via the direct delivery platform 46. The sorting platform 47 will then transport it to the other side for collection, thus completing the entire process. The second plate 6 is then conveyed to the conveyor table 24. Of course, the waste rack 23 also has a front positioning cylinder 51 and a front positioning plate 52, which can block the front end of plate 6 and position plate 6.

[0060] With the above structure, there is no need to replace the bottom template after changing products, which not only improves production efficiency but also reduces waste and makes production more environmentally friendly.

[0061] The above provides a detailed description of an automated die-cutting intelligent production line for foamed boards provided by embodiments of the present invention.
