Description

Technical Field

[0001] This invention relates to a foamed board production equipment, and more particularly to a needle-punching lifting and waste removal device for a punching forming line. Background Technology

[0002] EVA material (also known as foam) is widely used in many fields such as daily life and production. Generally, EVA material is made into raw materials for sheets and supplied to downstream processing manufacturers. The downstream processing manufacturers then punch and shape the sheets. After punching and shaping, the punched modules need to be ejected from the sheets by a waste removal machine to form individual products.

[0003] A typical waste removal machine generally consists of two parts: an upper stamping table with a die or several punches, and a lower bottom platen and a conveyor below the bottom platen. The stamped sheet is conveyed to the bottom platen. The positions of the punches, as well as the specifications of the die and bottom platen, are set according to the shape of the product and its position on the sheet. When the stamping table drives the die or punches to impact the module, the module is punched out from the corresponding holes in the sheet and the bottom platen onto the conveyor. The remaining waste material on the sheet remains on the bottom platen through its support and is collected manually.

[0004] After the above-mentioned waste removal machine changes the product, if it is a punch rod, the position of the punch rod needs to be readjusted; if it is a die, the die needs to be replaced. Moreover, the bottom template below needs to be replaced according to the shape of the product and its position on the sheet metal, thus reducing production efficiency. After the product is produced, the die and bottom template can only be destroyed, resulting in waste.

[0005] Therefore, the applicant designed a needle-punching lifting and waste discharge device for a punching forming line to solve the problem. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a needle-punching type lifting and waste discharge device for punching forming lines.

[0007] The technical solution adopted by this invention to solve its technical problem is:

[0008] A needle-type lifting and waste removal device for a punching forming line includes a punching table and a die or punch rod disposed below the punching table. It includes a waste removal frame and a conveyor table. The waste removal frame is equipped with a plate lifting mechanism for lifting the plate from the conveyor table. The punching table can drive the die or punch rod to punch the lifted plate, thereby punching out modules embedded in the plate onto the conveyor table. The plate lifting mechanism includes a needle, a needle-driving mechanism for driving the needle to pierce or pull out the plate, and a needle-lifting mechanism for driving the needle to rise and fall. The needle-lifting mechanism includes a needle-lifting driving unit disposed on the waste removal frame, a needle-chain transmission mechanism connected to the needle-lifting driving 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 rise and fall. The needle-driving mechanism and the needle are disposed on the needle-lifting frame.

[0009] The needle lifting frame is provided with a needle mounting plate, and the needle driving mechanism includes a needle cylinder fixed on the needle mounting plate, and the needle is connected to the needle cylinder.

[0010] The needle driving mechanism also includes a needle cylinder two fixed to the needle mounting plate, and the needle cylinder two is connected to a needle two.

[0011] The needle-punching mounting plate is equipped with a material-blocking cylinder and a material-blocking plate connected to the material-blocking cylinder.

[0012] 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.

[0013] The needle mounting plate is provided with an extension plate and a pressure plate fixed to the extension plate. Both the extension plate and the pressure plate are provided with needle guide holes, and the first needle and the second needle can pass through the corresponding needle guide holes.

[0014] The conveyor platform includes a direct conveyor and a sorting platform. The sorting platform is arranged perpendicularly to the direct conveyor, and the material conveyed by the direct conveyor can fall onto the sorting platform. Both ends of the sorting platform are material outlets.

[0015] Both the direct conveying station and the sorting station include a conveyor motor, two parallel conveyor rollers, a conveyor chain drive mechanism connected to the conveyor motor, and a conveyor belt mounted on the conveyor rollers. The conveyor chain drive mechanism is connected to the corresponding conveyor roller.

[0016] The beneficial effects of the present invention are as follows: The waste rack of the present invention is provided with a plate lifting mechanism for lifting the plate from the conveyor table. Therefore, after the plate lifting mechanism lifts the plate, the punch or die can punch the module off the plate and onto the conveyor table without the need for a bottom template, and then the plate is transported to the collection point by the conveyor table.

[0017] 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. Attached Figure Description

[0031] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0032] Reference Figures 1 to 6 This invention discloses a needle-punching type lifting and waste removal device for a punching forming line, including a waste removal frame 1 and a conveyor table 2. The conveyor table 2 is disposed on the waste removal frame 1, and the waste removal frame 1 is provided with a plate lifting mechanism for lifting the plate from the conveyor table 2. The waste removal frame 1 also includes a punching table 3 and a punching table lifting drive mechanism 4 for driving the punching table 3 to rise and fall. A punching die 5 is fixed below the punching table 3. The punching die 5 is generally made of wood, making it easy to manufacture and low in cost. The punching die 5 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.

[0033] After the punched sheet 6 is conveyed onto the conveyor table 2, the sheet lifting mechanism lifts the sheet 6, creating space between the sheet 6 and the conveyor table 2 for the module to fall. Therefore, when the stamping table 3, carrying the die 5, punches down, it can punch the module onto the conveyor table 2. After the module is conveyed, the sheet lifting mechanism can release the remaining waste material, allowing it to fall onto the conveyor table 2. Thus, the conveyor table 2 can simultaneously convey the fallen module and the remaining waste material to the collection point. Compared to previous waste discharge machines, this application uses a sheet 6 lifting method, thus eliminating the need for a bottom template. The conveyor table 2 below can directly convey both the module and the remaining waste material, thereby improving production efficiency, reducing waste, and making production more environmentally friendly.

[0034] As shown in the figure, the plate lifting mechanism includes a needle 7, a needle driving mechanism that drives the needle 7 to insert into or pull out the plate 6, and a needle lifting mechanism that drives the needle 7 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 twist and deform, and the clamping structure is complicated.

[0035] The needle lifting mechanism includes a needle lifting drive unit mounted on the waste removal frame 1, a needle chain drive mechanism 9 connected to the needle lifting drive unit, a needle screw assembly 10 connected to the needle chain drive mechanism 9, and a needle lifting frame 11 connected to and driven by the needle screw assembly 10. The needle drive mechanism and the needle 7 are mounted on the needle lifting frame 11. The needle lifting drive unit uses a common motor, and the needle chain drive mechanism 9 and the needle screw assembly 10 are also conventional chain drive structures, so details are not provided. Through the above structure, When the needle 7 pierces into both sides of the plate 6, the needle lifting drive unit works, driving the needle screw assembly 10 through the needle chain transmission mechanism 9, and driving the needle lifting frame 11 to rise and fall through the needle screw assembly 10, thereby realizing the lifting and falling of the needle 7 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 7 pierces in. Of course, the relative arrangement of the needle 7 in this application, and the needle lifting drive unit, needle chain transmission mechanism 9, needle screw assembly 10, and needle lifting frame 11 are also correspondingly and relatively arranged.

[0036] As a specific structure, for ease of installation, a needle mounting plate 12 is fixed on the needle lifting frame 11. The needle driving mechanism includes a needle cylinder 13 fixed on the needle mounting plate 12. The needle 7 is connected to the needle cylinder 13. Therefore, the needle cylinder 13 can directly push the needle 7 to move horizontally and insert it into the side of the plate 6. Of course, the needle 7 is fixed on the connecting plate, and the connecting plate is then fixed to the piston rod of the needle cylinder 13.

[0037] As a preferred structure, the needle-punching driving mechanism further includes a needle-punching cylinder 14 fixed on the needle-punching mounting plate 12. The needle-punching cylinder 14 is connected to a needle 15. The connection between the needle 15 and the needle-punching cylinder 14 is similar to the connection between the needle 7 and the needle-punching cylinder 13. The needle 15 is set vertically relative to the needle 7. Therefore, the needle 15 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 7 lifts the plate 6, the plate 6 will bend significantly. Moreover, the downward punching force of the die 5 is also considerable. This can easily cause the plate 6 to detach from the needle 7. Therefore, by restricting the vertical insertion of the needle 15, the needle 15 and the needle 7 form a three-dimensional fixing structure, thereby effectively preventing the plate 6 from easily falling off when the die 5 punches downward.

[0038] As a preferred structure, the needle mounting plate 12 is provided with an extension plate 16 and a pressure plate 17 fixed to the extension plate 16. Both the extension plate 16 and the pressure plate 17 are provided with needle guide holes 18. The first needle 7 and the second needle 15 can pass through the corresponding needle guide holes 18. After the plate 6 is located on the conveying table 2, the needle lifting drive unit will drive the needle lifting frame 11 and the needle mounting plate 12 to descend through the needle chain transmission mechanism 9, so that the pressure plate 17 can press down on the edge of the plate 6, which facilitates the subsequent insertion of the needles. The first needle 7 and the second needle 15 can play a supporting role through the corresponding needle guide holes 18.

[0039] As shown in the figure, the needle-punching lifting frame 11 is equipped with a spacing adjustment plate 19. The spacing adjustment plate 19 is equipped with a spacing adjustment motor 20, an adjustment chain transmission mechanism 21 connected to the spacing adjustment motor 20, and an adjustment screw assembly 22. The needle-punching mounting plate 12 is connected to the adjustment screw assembly 22 and moves. The spacing adjustment plate 19 is equipped with a guide linear bearing and a guide rod 23 that cooperates with the guide linear shaft. The guide rod 23 is connected to the needle-punching mounting plate 12. The spacing adjustment motor 20 is a common motor. The adjustment chain transmission mechanism 21 and the adjustment screw assembly 22 are also conventional belt drive structures, so they will not be described in detail.

[0040] Therefore, through the above structure, we can adjust the distance between the needle mounting plate 12 and the edge of the plate 6, so as to adapt to plates 6 of different widths. Moreover, the needle mounting plate 12 is provided with a baffle cylinder 24 and a baffle plate 25 connected to the baffle cylinder 24. Through the combination of the baffle cylinder 24 and the baffle plate 25, we can also achieve the purpose of positioning and correcting the plate 6. When the plate 6 is on the conveyor table 2, the baffle plate 25 is pushed out by the baffle cylinder 24. Then, the spacing adjustment motor 20 drives the needle mounting plate 12 to move closer to the edge of the plate 6 through the adjustment chain transmission mechanism 21 until the baffle plate 25 abuts against the two sides of the plate 6, thereby achieving the positioning and correction of the plate 6. After positioning, the baffle plate 25 is pulled back by the baffle cylinder 24. Then, the needle lifting drive unit will drive the needle lifting frame 11 and the needle mounting plate 12 to descend through the needle chain transmission mechanism 9, so that the pressure plate 17 can press the edge of the plate 6, which is convenient for the subsequent insertion of the needle.

[0041] As shown in the figure, the conveying platform 2 includes a direct conveying platform 26 and a sorting platform 27. The sorting platform 27 is arranged perpendicularly to the direct conveying platform 26, and the material conveyed by the direct conveying platform 26 can fall onto the sorting platform 27. Both ends of the sorting platform 27 are material outlets. The direct conveying platform 26 is located below the stamping platform 3, while the sorting platform 27 is located to the side of the stamping platform 3. In this way, the punched-out modules and the remaining waste materials can fall onto the direct conveying platform 26 and then be conveyed to the sorting platform 27. If it is a module, the sorting platform 27 will convey it to one side for collection, and if it is waste material, the sorting platform 27 will convey it to the other side for collection, which facilitates the classification and collection of materials.

[0042] Specifically, both the direct conveyor 26 and the sorting station 27 include a conveyor motor 28, two parallel conveyor rollers, a conveyor chain drive mechanism 29 connected to the conveyor motor 28, and a conveyor belt 30 mounted on the conveyor rollers. The conveyor chain drive mechanism 29 is connected to the corresponding conveyor rollers. Therefore, through the combined action of the conveyor motor 28, the conveyor chain drive mechanism 29, and the two conveyor rollers, the conveyor belt 30 is rotated, thereby realizing the conveying of modules and remaining waste materials. The conveyor motor 28 is a common motor, and the conveyor chain drive mechanism 29 and the conveyor rollers are conventional transmission structure combinations, so they will not be described in detail.

[0043] The working process of this application is briefly described as follows: When the sheet material 6 is delivered to the conveyor table 2, the baffle plate 25 is extended by the baffle cylinder 24. Then, the spacing adjustment motor 20 drives the needle mounting plate 12 to move closer to the edge of the sheet material 6 through the adjustment chain transmission mechanism 21 until the baffle plate 25 abuts against the two sides of the sheet material 6, thereby achieving the positioning and correction of the sheet material 6. After positioning, the baffle plate 25 is pulled back by the baffle cylinder 24. Then, the needle lifting drive unit drives the needle lifting frame 11 and the needle mounting plate 12 to descend through the needle chain transmission mechanism 9, so that the pressure plate 17 can press the edge of the sheet material 6. Then, the needle cylinder 13 and the needle cylinder 24 start to work, respectively driving the needle 17 and the needle 25 to penetrate the sheet material 6 to fix the sheet material 6. Then, the needle lifting drive unit drives the needle lifting frame 11 and the needle mounting plate 12 through the needle chain transmission mechanism 9. 12. After the plate 6 is raised and reset, there is a gap between the plate 6 and the conveyor table 2. Then, the punching table lifting drive mechanism 4 drives the punching table 3 and the punching die 5 to punch down, so that the module falls onto the direct delivery table 26. The punching table 3 and the punching die 5 are reset. Then, the module is conveyed to the sorting table 27 through the direct delivery table 26. The sorting table 27 will convey it to one side for collection. Then, the second needle cylinder 14 starts to move, driving the second needle 15 to retract and be pulled out from the plate 6. Then, the first needle cylinder 13 starts to move, driving the first needle 7 to retract and be pulled out from the plate 6. The plate 6 will fall onto the direct delivery table 26 and then be conveyed to the sorting table 27 through the direct delivery table 26. The sorting table 27 will convey it to the other side for collection, thus completing the whole process. The second plate 6 is then conveyed to the conveyor table 2. Of course, there is also a front positioning cylinder 31 and a front positioning plate 32 on the waste rack 1, which can block the front end of the plate 6 and position the plate 6.

[0044] The above provides a detailed description of a punching forming line needle-type lifting and waste removal device provided by the embodiments of the present invention. Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
