Description

Technical Field

[0001] This invention relates to the field of industrial waste treatment technology, and in particular to a high-efficiency and environmentally friendly packing machine. Background Technology

[0002] With the continuous development of industrialization, a large amount of industrial waste such as waste paper, waste metal and waste plastic has been generated. As for waste paper, it can be recycled and reused. Currently, after recycling, waste paper needs to be compressed and packaged for easy transportation.

[0003] For example, the invention patent with authorization announcement number CN114506115B discloses an integrated recycling system for waste paper baling and recycling. The buffer box is opened and closed by the opening and closing mechanism, and the compression baling device is started to squeeze and compress the waste paper. Meanwhile, the conveyor belt continues to transport the waste paper into the buffer box. Therefore, when the compression baling device squeezes and compresses the waste paper, the conveyor belt does not need to stop running, saving the conveying time spent on adding waste paper into the machine, thus improving the baling efficiency of waste paper.

[0004] However, when the aforementioned equipment and similar existing equipment bundle waste paper after it has been compressed into blocks, they mostly use wire or strapping to bind and bundle the waste paper. Since the contact area between the wire and strapping and the waste paper blocks is limited, the areas on the surface of the waste paper blocks that are not in contact with the wire or strapping are very prone to peeling off as the transportation process continues to bump. This not only affects the overall quality of the waste paper blocks, but also increases the difficulty of unloading after transportation, thereby increasing unnecessary labor costs.

[0005] Therefore, it is necessary to invent a high-efficiency and environmentally friendly packing machine to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a high-efficiency and environmentally friendly paper baling machine. During the paper baling process, hot melt adhesive is used to wrap and bale the paper, resulting in a larger contact area. This avoids localized peeling of the paper surface, ensuring the overall quality of the paper while minimizing unloading difficulties. The adhesive layer also improves the waterproof performance of the paper, reducing the difficulty of waterproofing during transportation. This addresses the problem mentioned in the background art where, after the paper is compressed into blocks, it is often bundled with wire or strapping. Because the contact area between the wire and strapping and the paper is limited, areas on the paper surface not in contact with the wire or strapping are prone to peeling during transport due to constant jolting. This not only affects the overall quality of the paper but also increases the difficulty of unloading after transportation, leading to unnecessary labor costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency and environmentally friendly paper compression machine, comprising a shell assembly, wherein a forming mechanism for accommodating waste paper to be compressed is provided at the bottom of the inner cavity of the shell assembly, and a hot melt adhesive packaging mechanism for forming a solidified hot melt adhesive layer on the surface of the waste paper block is provided at the top of the inner cavity of the shell assembly, wherein a pressing mechanism for compressing waste paper into waste paper blocks is connected to the bottom of the hot melt adhesive packaging mechanism, and an ejection mechanism for ejecting the compressed waste paper blocks is provided at the rear of the shell assembly.

[0008] Preferably, the housing assembly includes a base, a housing is fixedly mounted on the top of the base, clearance channels are provided on both sides of the top of the housing, and an inclined feeding rack is fixedly nested on the left side of the housing.

[0009] Preferably, the molding mechanism includes a molding outer frame fixedly disposed on the top of the base, a pressure equalization hole is provided at the bottom of the back of the molding outer frame, a lifting plate is slidably attached to the inner side of the molding outer frame in the vertical direction, and a sealing element is provided between the outer wall of the lifting plate and the inner wall of the molding outer frame.

[0010] Preferably, a guide groove is provided on the rear side inside the molded outer frame, and an L-shaped lifting plate is slidably arranged on the inner side of the guide groove along the vertical direction. The L-shaped lifting plate is fixedly connected to the rear end of the lifting plate.

[0011] Preferably, the hot melt adhesive packaging mechanism includes a piston cylinder fixedly disposed through the top of the housing, a limiting post fixedly disposed through the top of the inner cavity of the piston cylinder, a piston plate that slides vertically against the bottom end of the limiting post and is attached to the inside of the piston cylinder, a piston rod fixedly disposed at the bottom of the piston plate, an end plate fixedly disposed at the bottom end of the piston rod, and a magnet A fixedly connected to the end plate and sleeved on the outside of the piston rod.

[0012] Preferably, the hot melt adhesive packaging mechanism further includes a glue supply pipe fixedly disposed through the top of the back of the piston cylinder and two glue outlet pipes fixedly disposed through the top of both sides of the piston cylinder. Each glue supply pipe and the two glue outlet pipes are equipped with a one-way valve. The bottom ends of the two glue outlet pipes are connected to a diversion pipe. The four output ends of the diversion pipe are fixedly disposed through the bottom of the four sides of the molding outer frame.

[0013] Preferably, the pressing mechanism includes a fixed plate fixedly disposed inside the housing, a main hydraulic cylinder fixedly disposed on the top of the fixed plate, a forming pressing plate fixedly disposed at the bottom end of the output shaft of the main hydraulic cylinder, an L-shaped lifting plate attached to the back of the forming pressing plate, and the horizontal part of the L-shaped lifting plate attached to the top of the forming pressing plate.

[0014] Preferably, the top center of the forming plate is fixedly provided with an inverted U-shaped frame that is slidably sleeved on the outside of the piston rod in the vertical direction, and the top of the inner side of the inverted U-shaped frame is fixedly provided with a magnet B that is attracted to the magnet A directly above it.

[0015] Preferably, the ejection mechanism includes a secondary hydraulic cylinder fixedly disposed on the rear side of the housing, the output shaft of the secondary hydraulic cylinder slidingly passing through the outer wall of the housing and extending into the interior of the housing, a push plate being attached to the rear top of the forming frame, and the back of the push plate being fixedly connected to the output shaft of the secondary hydraulic cylinder.

[0016] Preferably, it also includes a method for using a high-efficiency and environmentally friendly packing machine, specifically including the following steps:

[0017] S1. Waste paper slides down the inner wall of the inclined feeding rack into the forming frame under the action of gravity to achieve feeding. After feeding is completed, the main hydraulic cylinder drives the forming plate to move down continuously, thereby moving the forming plate into the forming frame. During this process, the inverted U-shaped frame drives the piston rod to move down through the end plate. When the piston rod moves down, it drives the piston plate to move down continuously inside the piston cylinder, thereby allowing hot melt adhesive to be continuously input into the piston cylinder through the glue supply pipe.

[0018] S2. As the forming plate moves down, it enters the outer frame and continuously compresses the waste paper inside until it is compressed into a block. During this process, the air in the waste paper is discharged through the gap between the outer frame and the forming plate, and the hot melt adhesive is quantitatively sucked up.

[0019] S3. The main hydraulic cylinder drives the forming plate to move up and reset. During this process, the forming plate gradually separates from the top of the waste paper block. At the same time, magnet B drives the end plate to move up synchronously through magnet A. When the end plate moves up, it drives the piston plate to move up inside the piston cylinder through the piston rod. This allows the hot melt adhesive inside the piston cylinder to enter the distribution pipe through the glue outlet pipe. Then, it is output from the distribution pipe to the four sides of the waste paper block and the inner wall of the forming outer frame and diffuses. Finally, a coating adhesive layer is formed on the four sides of the waste paper block.

[0020] S4. After the forming plate is reset, the piston plate simultaneously abuts against the bottom of the limit post. At this time, the piston plate, piston rod and end plate cannot continue to move upward. The main hydraulic cylinder continues to drive the forming plate to rise. At this time, magnet B is separated from the top of magnet A. At the same time, the forming plate drives the lifting plate to move upward through the L-shaped lifting plate. When the lifting plate moves upward, it drives the waste paper block after being packaged on its top to move upward synchronously until the top of the lifting plate is flush with the top opening of the forming outer frame.

[0021] S5. The auxiliary hydraulic cylinder drives the push plate forward, which pushes the packaged waste paper blocks and outputs them. Then the main hydraulic cylinder drives the forming plate to move down and reset, and the auxiliary hydraulic cylinder drives the push plate to move back and reset. After the forming plate is reset, magnet B is attracted to the top of magnet A again.

[0022] The technical effects and advantages of this invention are as follows:

[0023] This invention incorporates a forming mechanism and a hot melt adhesive packaging mechanism. During the compression process, as the briquetting mechanism moves downwards to compress waste paper into blocks, the hot melt adhesive packaging mechanism actively draws in the hot melt adhesive. When the briquetting mechanism subsequently moves upwards to reset, it removes the top obstruction of the waste paper blocks and simultaneously introduces the hot melt adhesive from the packaging mechanism into the forming mechanism, forming a coating layer on the outside of the waste paper blocks. Finally, the briquetting mechanism drives the forming mechanism to output the packaged waste paper blocks. Compared to existing technologies that use wire or strapping for binding and packaging, this invention utilizes hot melt adhesive for coating and packaging during the waste paper compression process. This results in a larger contact area, preventing localized peeling of the waste paper blocks and ensuring overall quality while avoiding increased unloading difficulty. The coating layer also improves the waterproof performance of the waste paper blocks, reducing the difficulty of waterproofing during transportation. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] This invention provides, for example Figure 1-6 The high-efficiency and environmentally friendly paper compression machine shown includes a shell assembly 1. The bottom of the inner cavity of the shell assembly 1 is provided with a forming mechanism 2 for accommodating waste paper to be compressed, and the top of the inner cavity of the shell assembly 1 is provided with a hot melt adhesive packaging mechanism 3 for forming a solidified hot melt adhesive layer on the surface of the waste paper block. The bottom of the hot melt adhesive packaging mechanism 3 is connected to a pressing mechanism 4 for compressing the waste paper into waste paper blocks. The rear side of the shell assembly 1 is provided with an ejection mechanism 5 for ejecting the compressed waste paper blocks.

[0034] like Figure 2 As shown, the outer casing assembly 1 includes a base 11, a housing 12 is fixedly mounted on the top of the base 11, and clearance channels 13 are provided on both sides of the top of the housing 12. An inclined feeding rack 14 is fixedly nested on the left side of the housing 12.

[0035] like Figure 3 As shown, the molding mechanism 2 includes a molding outer frame 21 fixedly installed on the top of the base 11. A pressure equalization hole is provided at the bottom of the back of the molding outer frame 21. A lifting plate 22 is slidably attached to the inner side of the molding outer frame 21 in the vertical direction. A sealing element is provided between the outer wall of the lifting plate 22 and the inner wall of the molding outer frame 21. A guide groove 23 is provided on the rear side of the inner side of the molding outer frame 21. An L-shaped lifting plate 24 is slidably installed on the inner side of the guide groove 23 in the vertical direction. The L-shaped lifting plate 24 is fixedly connected to the rear end of the lifting plate 22.

[0036] By setting up the outer shell assembly 1 and the forming mechanism 2, the waste paper can slide down the inner wall of the inclined feeding rack 14 under gravity and be fed into the forming outer frame 21. When the forming pressure plate 43 moves the lifting plate 22 upward through the L-shaped lifting plate 24, the lifting plate 22 moves the waste paper block packed on top of it upward synchronously until the top of the lifting plate 22 is flush with the top opening of the forming outer frame 21, so as to facilitate the subsequent ejection of the waste paper block.

[0037] like Figure 4As shown, the hot melt adhesive packaging mechanism 3 includes a piston cylinder 31 fixedly disposed through the top of the housing 12. A limiting post 32 is fixedly disposed through the top of the inner cavity of the piston cylinder 31. A piston plate 33, which slides vertically and is attached to the bottom of the limiting post 32, is attached to the inside of the piston cylinder 31. A piston rod 34 is fixedly disposed at the bottom of the piston plate 33. An end plate 35 is fixedly disposed at the bottom of the piston rod 34. A magnet A36, which is fixedly connected to the end plate 35, is sleeved on the outside of the piston rod 34. The hot melt adhesive packaging mechanism 3 also includes a glue supply pipe 37 fixedly disposed through the top of the back of the piston cylinder 31 and two glue outlet pipes 38 fixedly disposed through the top of both sides of the piston cylinder 31. A one-way valve is provided on the glue supply pipe 37 and the two glue outlet pipes 38. The bottom of the two glue outlet pipes 38 are connected to a diversion pipe 39. The four output ends of the diversion pipe 39 are fixedly disposed through the bottom of the four sides of the molding frame 21.

[0038] By setting up the above structure, when the inverted U-shaped frame 44 moves downward, the piston rod 34 is driven downward by the end plate 35. When the piston rod 34 moves downward, it drives the piston plate 33 to move continuously downward inside the piston cylinder 31, so that the hot melt adhesive is continuously input into the piston cylinder 31 through the glue supply pipe 37. Subsequently, when the hot melt adhesive is quantitatively drawn up and the magnet B45 moves upward synchronously by the magnet A36, the end plate 35 drives the piston plate 33 to move upward inside the piston cylinder 31 through the piston rod 34, so that the hot melt adhesive inside the piston cylinder 31 enters the distribution box through the glue outlet pipe 38. The waste paper is fed into the flow tube 39 and then distributed through the branch tube 39 to the area between the four sides of the waste paper block and the inner wall of the forming frame 21, where it diffuses and forms a coating adhesive layer on the four sides of the waste paper block. Compared with the existing technology that uses wire or strapping for binding and packaging, the hot melt adhesive is used to wrap and package the waste paper during the compression process. This results in a larger contact area, which can prevent local peeling of the waste paper block surface, ensuring the overall quality of the waste paper block while avoiding increasing the difficulty of unloading. The coating adhesive layer can also improve the waterproof performance of the waste paper block around its perimeter, thereby reducing the difficulty of waterproofing it during transportation.

[0039] like Figure 5 As shown, the pressing mechanism 4 includes a fixed plate 41 fixedly installed inside the housing 12. A main hydraulic cylinder 42 is fixedly installed on the top of the fixed plate 41. A forming plate 43 is fixedly installed at the bottom end of the output shaft of the main hydraulic cylinder 42. An L-shaped lifting plate 24 is attached to the back of the forming plate 43. The horizontal part of the L-shaped lifting plate 24 is attached to the top of the forming plate 43. An inverted U-shaped frame 44 is fixedly installed at the top center of the forming plate 43 and is slidably sleeved on the outside of the piston rod 34 in the vertical direction. A magnet B45 is fixedly installed on the top of the inner side of the inverted U-shaped frame 44 and is attracted to the magnet A36 directly above it.

[0040] By setting the above structure, the main hydraulic cylinder 42 can drive the forming plate 43 to move continuously downward, thereby moving the forming plate 43 into the forming outer frame 21. As the forming plate 43 moves downward, it enters the forming outer frame 21 and continuously compresses the waste paper inside the forming outer frame 21 until the waste paper inside the forming outer frame 21 is compressed into a waste paper block. During this process, the air in the waste paper is discharged through the gap between the forming outer frame 21 and the forming plate 43, thereby preventing the waste paper block from becoming loose due to excessive air inside. Then, the main hydraulic cylinder 42 drives the forming plate 43 to move upward and reset. During this process, the forming plate 43 gradually detaches from the top of the waste paper block.

[0041] like Figure 6 As shown, the ejection mechanism 5 includes a secondary hydraulic cylinder 51 fixedly disposed on the rear side of the housing 12. The output shaft of the secondary hydraulic cylinder 51 slides through the outer wall of the housing 12 and extends into the interior of the housing 12. A push plate 52 is attached to the rear side of the top of the forming frame 21. The back of the push plate 52 is fixedly connected to the output shaft of the secondary hydraulic cylinder 51.

[0042] By setting up the above structure, after the top of the lifting plate 22 is flush with the top opening of the forming outer frame 21, the auxiliary hydraulic cylinder 51 drives the push plate 52 to move forward, thereby pushing the packaged waste paper block out. Then, the auxiliary hydraulic cylinder 51 drives the push plate 52 to move backward and reset, waiting for the next push-out operation.

[0043] This invention also includes a method for using a high-efficiency and environmentally friendly packing machine, specifically comprising the following steps:

[0044] S1. Waste paper slides down the inner wall of the inclined feeding rack 14 under gravity and into the forming outer frame 21 to achieve feeding. After feeding is completed, the main hydraulic cylinder 42 drives the forming plate 43 to move down continuously, thereby moving the forming plate 43 into the forming outer frame 21. During this process, the inverted U-shaped frame 44 drives the piston rod 34 to move down through the end plate 35. When the piston rod 34 moves down, it drives the piston plate 33 to move down continuously inside the piston cylinder 31, thereby allowing hot melt adhesive to be continuously input into the piston cylinder 31 through the glue supply pipe 37.

[0045] S2. As the forming plate 43 moves down, it enters the forming frame 21 and continuously compresses the waste paper inside the forming frame 21 until the waste paper inside the forming frame 21 is compressed into a waste paper block. During this process, the air in the waste paper is discharged through the gap between the forming frame 21 and the forming plate 43, and the hot melt adhesive completes quantitative suction.

[0046] S3. The main hydraulic cylinder 42 drives the forming plate 43 to move upward and reset. During this process, the forming plate 43 gradually detaches from the top of the waste paper block. At the same time, the magnet B45 drives the end plate 35 to move upward synchronously through the magnet A36. When the end plate 35 moves upward, the piston rod 34 drives the piston plate 33 to move upward inside the piston cylinder 31. This allows the hot melt adhesive inside the piston cylinder 31 to enter the distribution pipe 39 through the glue outlet pipe 38. Then, it is output from the distribution pipe 39 to the space between the four sides of the waste paper block and the inner wall of the forming outer frame 21 and diffuses, eventually forming a coating adhesive layer on the four sides of the waste paper block.

[0047] S4. After the forming plate 43 is reset, the piston plate 33 simultaneously abuts against the bottom of the limiting post 32. At this time, the piston plate 33, piston rod 34 and end plate 35 cannot continue to move upward. The main hydraulic cylinder 42 continues to drive the forming plate 43 to rise. At this time, the magnet B45 is disengaged from the top of the magnet A36. At the same time, the forming plate 43 drives the lifting plate 22 to move upward through the L-shaped lifting plate 24. When the lifting plate 22 moves upward, it drives the waste paper block after being packaged on its top to move upward synchronously until the top of the lifting plate 22 is flush with the top opening of the forming outer frame 21.

[0048] S5, the auxiliary hydraulic cylinder 51 drives the push plate 52 to move forward. When the push plate 52 moves forward, it pushes the packaged waste paper blocks and outputs them. Then the main hydraulic cylinder 42 drives the forming plate 43 to move down and reset. The auxiliary hydraulic cylinder 51 drives the push plate 52 to move backward and reset. After the forming plate 43 is reset, the magnet B45 is attracted to the top of the magnet A36 again.

[0049] Example 2

[0050] Unlike the above embodiments, the front of the housing 12 has a waste paper block output port in the middle, and a waste paper block conveyor belt that cooperates with the waste paper block output port is fixedly installed at the bottom of the front of the housing 12.

[0051] By setting up the above structure, the packaged waste paper blocks can pass through the waste paper block output port when being output, and then fall onto the waste paper block conveyor belt for output, thereby reducing the difficulty of waste paper block output.

[0052] Example 3

[0053] Unlike the above embodiments, the molded outer frame 21 is provided with a cooling device for cooling the hot melt adhesive.

[0054] By setting up the above structure, the refrigeration equipment can be activated after the hot melt adhesive is coated on the outside of the waste paper block. The refrigeration equipment cools down the hot melt adhesive layer, thereby increasing the solidification speed of the hot melt adhesive.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

At this time, the piston plate (33), piston rod (34) and end plate (35) cannot continue to move upward. The main hydraulic cylinder (42) continues to drive the forming plate (43) to rise. At this time, magnet B (45) is separated from the top of magnet A (36). At the same time, the forming plate (43) drives the lifting plate (22) to move upward through the L-shaped lifting plate (24). When the lifting plate (22) moves upward, it drives the waste paper block after packaging on its top to move upward synchronously until the top of the lifting plate (22) is flush with the top opening of the forming outer frame (21). S5. The auxiliary hydraulic cylinder (51) drives the push plate (52) to move forward. When the push plate (52) moves forward, it pushes the packaged waste paper blocks and outputs the packaged waste paper blocks. Then the main hydraulic cylinder (42) drives the forming plate (43) to move down and reset. The auxiliary hydraulic cylinder (51) drives the push plate (52) to move backward and reset. After the forming plate (43) is reset, the magnet B (45) is attracted to the top of the magnet A (36) again.
