Description

Technical Field

[0001] This utility model relates to a waste discharge machine, and more particularly to a pneumatic waste discharge machine. Background Technology

[0002] Ordinary waste removal machines use punches to remove the pre-cut graphic blocks from the pearl cotton sheet.

[0003] However, the above-mentioned waste removal machine (application number: 202220680582.2, utility model name: conveyor belt type CNC waste removal machine) uses a punch frame to drive the punch rod down, which punches the graphic block corresponding to the punch rod out of the pearl cotton board, thereby realizing the separation of the graphic block from the pearl cotton board material.

[0004] The aforementioned waste removal machine has a complex structure, requiring the installation of numerous punches on the punching frame. Furthermore, once the pearl cotton sheet with different shaped graphic blocks is replaced, the position and number of punches need to be readjusted, which is not only time-consuming but also labor-intensive for operators and results in low production efficiency. Therefore, the applicant has designed a pneumatic waste removal machine to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a wind pressure waste discharge machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A pneumatic waste discharge machine is characterized by comprising a frame, a material platform mounted on the frame, a blower, and an air knife connected to the blower. The material platform is provided with a waste discharge hole, and the plate material on the material platform can be blown into the waste discharge hole by the air knife.

[0008] The frame is equipped with a lifting frame that can be raised and lowered, and the air knife is mounted on the lifting frame. The lifting frame is adjusted in height by a lifting adjustment mechanism.

[0009] It also includes a roller drive mechanism, an upper drive roller and a lower drive roller. The upper drive roller is mounted on a lifting frame, the lower drive roller is mounted on a material platform, and the roller drive mechanism is mounted on a frame. The roller drive mechanism can simultaneously drive the upper drive roller and the lower drive roller to rotate, thereby moving the sheet material located between the upper drive roller and the lower drive roller.

[0010] It also includes an upper pressure roller and a lower pressure roller. The upper pressure roller is mounted on the lifting frame, and the lower pressure roller is mounted on the material platform. The upper and lower pressure rollers can press the corresponding surfaces of the material plate to prevent the material plate from bending and deforming.

[0011] It also includes a pressure roller position adjustment mechanism, which includes a connecting plate, an upper elongated hole on the lifting frame, a rack on the material platform, and a lower elongated hole. The lower pressure roller has a gear at its end that meshes with the rack and a handwheel at its end. The connecting plate has a lifting elongated hole. The end of the upper pressure roller is located in the upper elongated hole and the lifting elongated hole. The end of the lower pressure roller is located in the lower elongated hole and is fixed to the connecting plate. The connecting plate can be locked by locking screws engaging with corresponding locking holes on the material platform.

[0012] The lifting and adjusting mechanism includes an adjusting screw, an adjusting nut, and a lifting shaft fixed to the frame, all arranged opposite to each other. The lifting frame has a sliding hole that mates with the lifting shaft. The adjusting screw is rotatably connected to the frame, and the adjusting nut is fixed to the lifting frame and threadedly connected to the adjusting screw. Each adjusting screw has an adjusting sprocket, and the adjusting sprockets are connected to each other by an adjusting chain. The frame has a positioning seat, which has a locking screw hole and a locking screw that mates with the locking screw hole. The end of the locking screw has a locking block that can contact the adjusting screw.

[0013] The roller drive mechanism includes a roller drive motor mounted on the frame, a sprocket one mounted on the roller drive motor, a sprocket two mounted on the lower drive roller, and a transmission chain one mounted on the sprocket one and the sprocket two. An adaptive chain drive structure is provided between the upper drive roller and the lower drive roller.

[0014] The adaptive chain drive structure includes an elastic tensioning mechanism, a second drive chain, a third sprocket mounted on the lower drive roller, a fourth and a fifth sprocket mounted on the upper drive roller, and a sixth sprocket mounted on the lifting frame. The lower drive roller is mounted on the frame and rotates via a roller drive mechanism. The second drive chain is mounted on the third, fourth, fifth, and sixth sprockets. The fifth sprocket is mounted on the frame via the elastic tensioning mechanism, and the elastic tensioning mechanism can apply an elastic force to tension the second drive chain. The lower drive roller drives the upper drive roller to rotate via the second drive chain.

[0015] The elastic tensioning mechanism includes an adaptive spring, a self-adjusting frame, and a fixed base fixed to the frame. The sprocket five is disposed on the self-adjusting frame, and the adaptive spring is disposed between the self-adjusting frame and the fixed base and can apply an elastic force to the self-adjusting frame, thereby tensioning the transmission chain two through the sprocket five.

[0016] A conveyor platform is located below the waste discharge hole.

[0017] The beneficial effects of this invention are as follows: This invention uses a high-speed airflow from an air knife to blow the cut graphic blocks from the sheet metal into the waste discharge hole, thereby achieving separation of the graphic blocks from the sheet metal. The above structure eliminates the need for punches and punch rods, resulting in a simple structure. Furthermore, when replacing the pearl cotton sheet metal with other shaped graphic blocks, there is no need to readjust the position and number of punch rods, thus saving significant production time, improving production efficiency, and reducing the labor intensity of the operators.

[0032] 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.

[0033] Reference Figure 1 , Figure 2This utility model discloses a pneumatic waste removal machine, including a frame 1, a material platform 2 mounted on the frame 1, a blower 3, and an air knife 4 connected to the blower 3. The material platform 2 is provided with a waste removal hole 5, and the sheet material on the material platform 2 can be blown into the waste removal hole 5 by the air knife 4. In the above structure, the air knife 4 is preferably located directly above the waste removal hole 5. The sheet material can be manually conveyed onto the material platform 2. When the sheet material passes through the waste removal hole 5, the graphic block has no support underneath and will fall off the sheet material under the impact of the high-speed airflow blown out by the air knife 4 and fall into the waste removal hole 5 for collection. Of course, the waste removal hole 5 is a rectangular hole, the length of which corresponds to the width of the sheet material, and the width of the waste removal hole 5 is greater than the size of the graphic block. The air knife 4 of this application has a conventional structural design, with a rectangular air cavity on top, and an air nozzle connected to the air cavity. The air nozzle has a trapezoidal structure that is wider at the top and narrower at the bottom, thereby achieving the function of pressurizing the air. An air outlet is provided on the narrowest side for air discharge.

[0034] Below the waste discharge hole 5 is a conveyor platform 6, which transports the graphic blocks to the collection point for collection. To prevent the graphic blocks from deviating, a funnel 7 is provided between the waste discharge hole 5 and the conveyor platform 6. The funnel 7 has a mesh wall, so the graphic blocks can fall onto the conveyor platform 6 through the funnel 7. The conveyor platform 6 uses belt conveying, which is existing technology, so the specific structure is not described in detail.

[0035] like Figure 3 and 4 As shown, the frame 1 is equipped with a lifting frame 8 that can be raised and lowered. The air knife 4 is mounted on the lifting frame 8. The lifting frame 8 is adjusted in height by a lifting adjustment mechanism. Because the thickness of the plates is different, the height of the air knife 4 needs to be adjusted according to the thickness of the plates. The specific structure of the lifting adjustment mechanism is as follows:

[0036] The lifting and adjusting mechanism includes an adjusting screw 9, an adjusting nut 10, and a lifting shaft 11 fixed to the frame 1, all arranged opposite to each other. The lifting frame 8 has a sliding hole that mates with the lifting shaft 11. The adjusting screw 9 is rotatably connected to the frame 1. Specifically, the non-threaded section of the adjusting screw 9 rotates with the frame 1 via a bearing, so the adjusting screw 9 will not move along the axis. The adjusting nut 10 is fixed to the lifting frame 8 and threadedly connected to the adjusting screw 9. Each adjusting screw 9 is equipped with an adjusting sprocket 12, and the adjusting sprockets 12 are connected by an adjusting chain 13. With the above structure, rotating any one adjusting screw 9 will cause both adjusting screws 9 to rotate simultaneously, which will drive the adjusting nut 10 to lift and lower, thereby realizing the lifting and lowering of the lifting frame 8 and the air knife 4. The adjusting screw 9 is selected with a thread that has a self-locking function, so it will not easily rotate automatically. Of course, the adjusting screw 9 is equipped with a handwheel for easy operation.

[0037] like Figure 7As shown, in order to further lock the position of the adjusting screw 9, the frame 1 is provided with a positioning seat 14. The positioning seat 14 is provided with a locking screw hole 15 and a locking screw 16 that cooperates with the locking screw hole 15. The end of the locking screw 16 is provided with a locking block 166 that can contact the adjusting screw 9. The locking block 166 is made of plastic to prevent damage to the adjusting screw. The adjusting screw 9 is locked by the locking screw 16, thereby achieving accurate maintenance of the height position of the lifting frame 8.

[0038] As shown in the figure, it also includes a roller drive mechanism, an upper drive roller 17 and a lower drive roller 18. The upper drive roller 17 is mounted on the lifting frame 8 via bearings, and the lower drive roller 18 is mounted on the material platform 2 via bearings. The roller drive mechanism is mounted on the frame 1, and the roller drive mechanism can simultaneously drive the upper drive roller 17 and the lower drive roller 18 to rotate, thereby moving the sheet material located between the upper drive roller 17 and the lower drive roller 18. With the above structure, after manual loading, the sheet material can be clamped by the upper drive roller 17 and the lower drive roller 18 and driven forward, thereby realizing the continuous passage of the sheet material through the air knife 4.

[0039] Specifically, it also includes an upper pressure roller 19 and a lower pressure roller 20. The upper pressure roller 19 is set on the lifting frame 8, and the lower pressure roller 20 is set on the material platform 2. The upper pressure roller 19 and the lower pressure roller 20 can press the corresponding surface of the material plate to prevent the material plate from bending and deforming. The upper pressure roller 19 is parallel to the upper drive roller 17 and has the same height. The lower pressure roller 20 is parallel to the lower drive roller 18 and has the same height. Of course, in order to better prevent the board from warping, an auxiliary pressure roller 21 is also provided. The upper pressure roller 19 and the auxiliary pressure roller 21 are arranged opposite each other on both sides of the upper drive roller 17.

[0040] It also includes a pressure roller position adjustment mechanism, which includes a connecting plate 22, an upper elongated hole 23 disposed on the lifting frame 8, a rack 24 disposed on the material platform 2, and a lower elongated hole 25. The lower pressure roller 20 has a gear 26 meshing with the rack 24 at its end and a handwheel at its end. The connecting plate 22 has a lifting elongated hole 27. The end of the upper pressure roller 19 is located in the upper elongated hole 23 and the lifting elongated hole 27, and the end of the lower pressure roller 20 is located in the lower elongated hole 25 and fixed to the connecting plate 22. The operator rotates the lower pressure roller 20 by the handwheel, and the lower pressure roller 20 moves along the lower elongated hole 25 through the gear 26. 5. When the lower pressure roller 20 moves, it drives the upper pressure roller 19 to move along the upper elongated hole 23 through the connecting plate 22, thereby realizing the synchronous adjustment of the positions of the upper pressure roller 19 and the lower pressure roller 20, and realizing the position adjustment between the upper pressure roller 19 and the upper drive roller 17, and between the lower pressure roller 20 and the lower drive roller 18. The connecting plate 22 can be locked by the locking screw cooperating with the corresponding locking hole 45 on the material platform 2. The connecting plate 22 has a locking elongated hole 46, and the material platform 2 has several locking holes 45. The locking screw can lock the connecting plate by cooperating with the locking elongated hole 46 and the corresponding locking hole 45.

[0041] When the lifting frame 8 is raised or lowered, the upper pressure roller 19 can move through the lifting elongated hole 27 to have lifting space. The upper pressure roller 19 and the lower pressure roller 20 of this application both include a pressure roller shaft and an outer roller. The outer roller is connected to the pressure roller shaft through a bearing. Therefore, the ends of the upper pressure roller 19 and the lower pressure roller 20 are both the ends of the pressure roller shaft. In this way, the pressure roller shaft does not rotate, but the outer roller rotates, which facilitates position adjustment.

[0042] The roller drive mechanism includes a roller drive motor 28 mounted on the frame 1, a sprocket 29 mounted on the roller drive motor 28, a sprocket 30 mounted on the lower drive roller 18, and a transmission chain 31 mounted on the sprocket 29 and the sprocket 30. An adaptive chain transmission structure is provided between the upper drive roller 17 and the lower drive roller 18. In the above, the roller drive motor 28 is an ordinary motor, and the sprocket 29 and the sprocket 30 are also conventional transmission components, so their specific structures are not described in detail. The upper drive roller 17 is driven to rotate by the roller drive motor 28, and the lower drive roller 18 drives the upper drive roller 17 to rotate through the adaptive chain transmission structure. Because the upper drive roller 17 of this application needs to rise and fall with the lifting frame 8, the adaptive chain transmission structure can also ensure that the upper drive roller 17 rotates.

[0043] The adaptive chain drive structure includes an elastic tensioning mechanism, a second transmission chain 32, a third sprocket 33 mounted on the lower drive roller 18, a fourth sprocket 34 and a fifth sprocket 35 mounted on the upper drive roller 17, and a sixth sprocket 36 mounted on the lifting frame 8. The lower drive roller 18 is mounted on the frame 1 and rotates via a roller drive mechanism. The second transmission chain 32 is mounted on the third sprocket 33, the fourth sprocket 34, the fifth sprocket 35, and the sixth sprocket 36. The fifth sprocket 35 is mounted on the frame 1 via the elastic tensioning mechanism and can be elastically tensioned. The tensioning mechanism applies an elastic force to tension the transmission chain 32. The lower drive roller 18 drives the upper drive roller 17 to rotate through the transmission chain 32. In the above structure, sprockets 35 and 36 are tensioning wheels that are not connected to the drive roller. Sprocket 35, in conjunction with the elastic tensioning mechanism, maintains the tension on the transmission chain 32, thereby ensuring that the transmission chain 32, sprockets 33 and 34 cooperate well. This ensures that the transmission chain 32 remains tensioned after the upper drive roller 17 is raised or lowered, thus ensuring that the upper drive roller 17 has power to drive it after both raising and lowering.

[0044] Specifically, sprockets 5 and 6 are positioned relative to and below sprocket 33, thereby forming a V-shape with the transmission chain 2 32. This arrangement allows sprockets 5 and 6 to apply tension to the transmission chain 2 32 symmetrically. Furthermore, when the upper drive roller 17 descends, sprocket 6 also descends, while sprocket 5 moves under the tension of the elastic tensioning mechanism, thus preventing the transmission chain 2 32 from becoming slack.

[0045] like Figure 5 and 6 As shown, the elastic tensioning mechanism includes an adaptive spring 37, a self-adjusting frame 38, and a fixed base 39 fixed to the frame 1. The sprocket 35 is disposed on the self-adjusting frame 38. The adaptive spring 37 is disposed between the self-adjusting frame 38 and the fixed base 39 and can apply an elastic force to the self-adjusting frame 38, thereby tensioning the transmission chain 32 through the sprocket 35. The above structure pushes the self-adjusting frame 38 through the elastic force of the adaptive spring 37, thereby driving the sprocket 35 to tension the transmission chain 32.

[0046] Specifically, the fixed base 39 is provided with a mounting groove 40, and the self-adjusting frame 38 includes a base plate 41 and side plates 42 disposed opposite to the base plate 41. The base plate 41 is located below the fixed base 39 and the side plates 42 are located on both sides of the fixed base 39. The groove wall of the mounting groove 40 is provided with a clearance elongated hole 43. The sprocket 35 is disposed on the side plate 42 via a bearing and a rotating shaft 44, and the rotating shaft 44 passes through the clearance elongated hole 43. The adaptive spring 37 is disposed between the base plate 41 and the fixed base 39. With the above structure, one end of the adaptive spring 37 abuts against the bottom surface of the fixed base 39, and the other end of the adaptive spring 37 abuts against the base plate 41, thereby causing the sprocket 35 to tension the transmission chain 32 by pulling the rotating shaft 44 through the self-adjusting frame 38.

[0047] As shown in the figure, the end of the rotating shaft 44 is provided with a limiting surface, which can abut against the wall of the avoidance elongated hole 43 to restrict the rotation of the rotating shaft 44.

[0048] The above provides a detailed description of a pneumatic waste discharge machine provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. 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 ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
