Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, specifically to a fully automatic re-film packaging machine. Background Technology

[0002] Heavy film packaging machines are commonly used automated equipment for filling and packaging plastic granules such as PE and PP. Existing heavy film packaging machines can generally achieve automatic weighing, automatic filling and automatic sealing functions, making them a fully automatic packaging machine.

[0003] However, in the automatic filling module of the heavy film packaging machine, for granular materials, the material enters the filling port through the feeding hopper, and the material is accompanied by a lot of dust. The material will be directly filled into the packaging belt through the filling port, which affects the quality of the finished product and results in poor finished product quality after the packaging is opened.

[0004] To address the aforementioned problems, the inventors proposed a fully automatic re-film packaging machine. Summary of the Invention

[0005] In order to solve the problem that dust and impurities during material filling affect the quality of finished products, the purpose of this invention is to provide a fully automatic re-film packaging machine.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a fully automatic heavy film packaging machine, including a frame, a conveying platform at the bottom of the frame, a filling pipe at the center of the upper surface of the frame, a rectangular dust collection box installed on the upper surface of the frame at the top of the filling pipe, a dust collection component at the bottom of the dust collection box, a dispersing component at the top of the dust collection box, a feeding hopper at the top of the dust collection box, a dispersing component at the bottom of the feeding hopper, and a timed feeding component at the bottom of the feeding hopper.

[0007] After being fed, the raw material enters the dust collector through the bottom of the feeding hopper and falls onto the horizontal plate. The rotation of the second rotating shaft drives the swing arm to rotate. One end of the swing arm is pre-selected to abut against one side of the inner wall of the rectangular groove, moving the moving plate away from the dust collector. Then, the end adjacent to the previous swing arm contacts the other side of the rectangular groove, pushing the moving plate closer to the dust collector. Through this operation, the second rotating shaft drives the swing arm, causing the moving plate to move back and forth repeatedly. This, in turn, pushes the horizontal plate back and forth repeatedly via the push block, causing the material falling onto the horizontal plate to fall through different second discharge holes. After passing through the horizontal plate, the particles are dispersed. At this time, the air blown by the fan blows out the impurities and dust far away, separating the two. Through the above steps, all particles are separated, increasing the gap between the material and the dust, so that the fan can better separate the dust from the material. The dust is blown by the fan onto the electrostatic adsorption membrane installed on the fixed frame for adsorption, ultimately achieving the purpose of separating dust from particles and completing the dust removal effect. Subsequently, the material is poured into the packaging bag through the filling pipe. Through the above operations, the purpose of particle dust removal is achieved during the material feeding process, improving the quality of raw materials leaving the factory and improving the finished product effect.

[0008] Preferably, the dispersing component includes a dispersing block, which is a cone-shaped block that is narrower at the top and wider at the bottom. A discharge port is formed between the bottom of the dispersing block and the inner wall of the feeding hopper. A drive shaft is fixedly installed at the center of the cone-shaped block. When the drive shaft rotates, the dispersing block fixedly installed on the drive shaft will rotate. When agglomerated particles enter the feeding hopper, particles of the appropriate size fall down because a discharge port is formed between the dispersing block and the inner wall of the feeding hopper. The agglomerated raw material particles will be abutted between the dispersing block and the inner wall of the feeding hopper, and the round protrusions will help to disperse the agglomerated particles, preventing the particles from accumulating together and causing dust to not be separated in time. The top of the drive shaft penetrates through the feeding hopper, and the inner wall of the feeding hopper is fixedly provided with round protrusions distributed in a ring around the dispersing block.

[0009] Preferably, the timed feeding assembly includes a fixed plate, which is fixedly disposed in the feeding hopper below the disintegrating block. A turntable is provided on the upper surface of the fixed plate. The sidewalls of the fixed plate and the turntable are fully attached to the sidewall of the feeding hopper. The sidewall of the turntable is slidably disposed on the sidewall of the feeding hopper. Four annularly distributed feeding holes are opened on the upper surface of the turntable. Two symmetrically distributed first discharge holes are opened on the turntable. The two first discharge holes always penetrate and correspond to two of the feeding holes simultaneously. The drive shaft is fixedly disposed at the center of the turntable. A grooved wheel is fixedly disposed at one end of the drive shaft located on the outer wall of the feeding hopper. Four movable grooves are opened on the grooved wheel that are opposite to the feeding holes. A first rotating shaft is fixedly disposed on the upper surface of the feeding hopper near the drive shaft. A swing plate is provided on the first rotating shaft below the turntable. A push block is fixedly disposed at the end of the swing plate away from the first rotating shaft. The push block can be movably inserted into the four annularly distributed movable grooves.

[0010] Preferably, the dispersing component includes a horizontal plate with a second discharge hole arranged in a rectangular pattern. Both ends of the horizontal plate movably penetrate the dust collector. A first support plate is fixedly and horizontally positioned below the horizontal plate on one side of the outer wall of the dust collector. A second rotating shaft is rotatably mounted on the first support plate. A swing rod, Y-shaped, is fixedly mounted on the upper end of the second rotating shaft near the horizontal plate. Vertical blocks are fixedly mounted on the upper surface of the first support plate at both ends of the second rotating shaft. Top rods are movably inserted into two of the vertical blocks. A movable plate is fixedly mounted between the two top rods, and a rectangular groove is formed at the center of the movable plate. The rectangular groove has a fan-shaped groove at its diagonal. One end of the swing rod abuts against one part of the rectangular groove. The top rod end near the dust collector is fixedly mounted on the horizontal plate. A connecting assembly is provided between the first rotating shaft and the second rotating shaft. The connecting assembly includes a connecting shaft, which is vertically arranged. The bottom of the connecting shaft is fixedly mounted on the top of the second rotating shaft. The top of the connecting shaft is fixedly connected to the second rotating shaft via a belt drive. A second support plate is fixedly mounted on the lower surface of the first support plate. A motor is mounted on the second support plate, and the output end of the motor is fixedly connected to the second rotating shaft.

[0011] Preferably, a feeding frame is fixedly provided on the inner wall of the dust collection box below the horizontal plate, and the four sides of the inner wall of the feeding frame are wedge-shaped.

[0012] Preferably, a fan is installed on the side of the dust collection box located below the feeding frame and close to the first support plate. A groove is opened on the inner wall of the dust collection box on the side opposite to the fan. A fixing frame is installed in the groove. An electrostatic adsorption membrane is installed in the fixing frame. A fixing block is installed on the side wall of the fixing frame. A fixing bolt is threaded into the fixing block. The fixing block is installed on the side wall of the dust collection box through the fixing block and the fixing bolt.

[0013] Preferably, a feed pipe is installed on the top side wall of the feed hopper.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In this invention, the use of dispersing blocks and round protrusions disperses agglomerated raw materials, preventing granular materials from accumulating and hindering timely dust separation. A timed feeding component allows for intermittent feeding, avoiding large-scale feeding that could lead to dense particle packing and affect subsequent dust removal. A second rotating shaft and swing rod drive the moving plate and horizontal plate to move repeatedly, causing the material to fall dispersedly through different second discharge holes. Through these steps, all granular materials are separated, increasing the gap between material and dust. This allows the fan to better separate dust from the material. The fan blows the dust onto an electrostatic adsorption membrane mounted on a fixed frame for adsorption, ultimately achieving the separation of dust and particles and completing the dust removal effect. Subsequently, the material is filled into packaging bags through a filling pipe. Through these operations, the dust removal process is completed during material feeding, improving the quality of raw materials and the finished product. Attached Figure Description

[0026] 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.

[0027] Example: Figure 1-8 As shown, the present invention provides a fully automatic heavy film packaging machine, including a frame 1, a conveying platform 101 at the bottom of the frame 1, a filling pipe 11 at the center of the upper surface of the frame 1, a rectangular dust collection box 3 installed on the upper surface of the frame 1 at the top of the filling pipe 11, a dust collection component at the bottom of the dust collection box 3, a dispersing component at the top of the dust collection box 3, a feeding hopper 12 at the top of the dust collection box 3, the bottom of the feeding hopper 12 being connected to the dust collection box 3, a dispersing component at the upper end of the inner wall of the feeding hopper 12, and a timed feeding component at the bottom of the feeding hopper 12.

[0028] The dispersing component includes a dispersing block 14, which is a cone-shaped block that is narrower at the top and wider at the bottom. A discharge port 141 is formed between the bottom of the dispersing block 14 and the inner wall of the feed hopper 12. A drive shaft 13 is fixedly installed at the center of the cone-shaped block. The top of the drive shaft 13 passes through the feed hopper 12. Circular protrusions 15 are fixedly arranged in a ring around the dispersing block 14 on the inner wall of the feed hopper 12.

[0029] By adopting the above technical solution, when the drive shaft 13 rotates, the dispersing block 14 fixedly installed on the drive shaft 13 will rotate. When the agglomerated particles enter the feed hopper 12, since the dispersing block 14 and the inner wall of the feed hopper 12 form a discharge port 141, particles of the appropriate size fall down. The agglomerated raw material particles will pass through the dispersing block 14 and the inner wall of the feed hopper 12, and the round protrusion 15 will break up the agglomerated raw material particles, so as to avoid the raw material particles from accumulating together and causing the dust to not be separated in time.

[0030] The timed feeding assembly includes a fixed plate 16, which is fixedly installed in the feeding hopper 12 below the disintegrating block 14. A turntable 17 is provided on the upper surface of the fixed plate 16. The sidewalls of both the fixed plate 16 and the turntable 17 are fully attached to the sidewall of the feeding hopper 12. The sidewall of the turntable 17 is slidably mounted on the sidewall of the feeding hopper 12. Four annularly distributed feeding holes 18 are provided on the upper surface of the turntable 17. Two symmetrically distributed first discharge holes 19 are also provided on the turntable 17. The two first discharge holes 19 are always aligned with two of the feeding holes 18. Correspondingly, the drive shaft 13 is fixedly set at the center of the turntable 17. The top of the drive shaft 13 is fixedly provided with a grooved wheel 2 at one end of the outer wall of the feed bin 12. The grooved wheel 2 has four movable grooves 21 that are opposite to the discharge hole 18. The upper surface of the feed bin 12 is fixedly provided with a first rotating shaft 22 near the drive shaft 13. The first rotating shaft 22 is provided with a swing plate 23 below the rotating plate. The end of the swing plate 23 away from the first rotating shaft 22 is fixedly provided with a push block 24. The push block 24 can be movably inserted into the four annularly distributed movable grooves 21 respectively.

[0031] By adopting the above technical solution, the first rotating shaft 22 drives the swing plate 23 and the push block 24 to rotate, so that the push block 24 pushes the grooved wheel 2 to rotate intermittently and continuously, so that the grooved wheel 2 drives the drive shaft 13 to rotate intermittently. The discharge hole 18 on the turntable 17 will intermittently correspond to the first discharge hole 19 on the fixed plate 16, so that the material entering the feed bin 12 is discharged intermittently through the discharge hole 18 and the first discharge hole 19, avoiding the dense particle density caused by a large amount of material being discharged at once, which would affect the subsequent dust removal.

[0032] The dispersing component includes a horizontal plate 31 with a second discharge hole 32 arranged in a rectangle on the horizontal plate 31. Both ends of the horizontal plate 31 movably pass through the dust collector 3. A first support plate 33 is fixedly and horizontally arranged below the horizontal plate 31 on one side of the outer wall of the dust collector 3. A second rotating shaft 39 is rotatably arranged on the first support plate 33. A swing rod 4 is fixedly arranged near the horizontal plate 31 at the upper end of the second rotating shaft 39. The swing rod 4 is Y-shaped. Upright blocks 34 are fixedly arranged at both ends of the second rotating shaft 39 on the upper surface of the first support plate 33. Top rods 35 are movably inserted on the two upright blocks 34. A moving plate 36 is fixedly arranged between the two top rods 35. A rectangular groove 37 is opened at the center of the moving plate 36. A fan-shaped groove 38 is opened at the diagonal of the rectangular groove 37. One end of the swing rod 4 abuts against one part of the rectangular groove 37. The end of the top rod 35 near the dust collector 3 is fixedly arranged on the horizontal plate 31. A connecting component is provided between the first rotating shaft 22 and the second rotating shaft 39.

[0033] By adopting the above technical solution, the second rotating shaft 39, in conjunction with the swing rod 4, drives the swing rod 4 to drive the moving plate 36 to move back and forth repeatedly. The push block 24 pushes the horizontal plate 31 to move back and forth repeatedly, so that the horizontal plate 31 moves continuously, thereby causing the material falling onto the horizontal plate 31 to fall through different second discharge holes 32, so that the material is dispersed after passing through the horizontal plate 31.

[0034] The connecting assembly includes a connecting shaft 5, which is vertically arranged. The bottom of the connecting shaft 5 is fixedly disposed on the top of the second rotating shaft 39, and the top of the connecting shaft 5 is fixedly connected to the second rotating shaft 39 via a belt 51.

[0035] By adopting the above technical solution and setting up connecting components, the first rotating shaft 22 and the second rotating shaft 39 are driven to rotate synchronously, which increases the overall linkage of the device, while reducing the installation of electrical equipment and lowering costs.

[0036] A second support plate 42 is fixedly provided on the lower surface of the first support plate 33. A motor 41 is installed on the second support plate 42, and the output end of the motor 41 is fixedly connected to the second rotating shaft 39.

[0037] By adopting the above technical solution, the motor 41 can provide sufficient power to drive the first rotating shaft 22 and the second rotating shaft 39 to rotate, which is convenient for the staff to use. The second support plate 42 is fixedly set in a U-shape on the lower surface of the first support plate 33 to support the motor 41 and enable it to work stably.

[0038] A feeding frame 311 is fixedly installed on the inner wall of the dust collection box 3 below the horizontal plate 31. The four sides of the inner wall of the feeding frame 311 are wedge-shaped.

[0039] By adopting the above technical solution and setting up the feeding frame 311, the material can be concentrated and fall down, and then blown by the fan 43.

[0040] A fan 43 is installed on the side of the dust collection box 3 located below the feeding frame 311 and close to the first support plate 33. A groove 44 is opened on the inner wall of the dust collection box 3 on the side opposite to the fan 43. A fixing frame 45 is installed in the groove 44, and an electrostatic adsorption film 46 is installed in the fixing frame 45.

[0041] By adopting the above technical solution, the wind force blown out by the fan 43 blows out the impurities or dust far away, so that the two are separated. The dust is blown by the fan 43 onto the fixed frame 45 and the electrostatic adsorption film 46 is installed for adsorption, and finally the purpose of separating dust and particles is achieved.

[0042] A fixing block 47 is installed on the side wall of the fixing frame 45, and a fixing bolt 48 is threaded into the fixing block 47. The fixing block 47 is installed on the side wall of the dust collector 3 through the fixing block 47 and the fixing bolt 48.

[0043] By adopting the above technical solution, the fixing bolts 48 and fixing blocks 47 can easily install the fixing frame 45 on the dust collection box 3, and at the same time facilitate subsequent disassembly.

[0044] A feed pipe 25 is installed on the top side wall of the feed hopper 12.

[0045] By adopting the above technical solution, the feed pipe 25 can be connected to an external conveying device to transport materials into the feed hopper 12.

[0046] Working principle: During use, the material enters the feeding hopper 12 through the feed pipe 25. The motor 41 drives the first rotating shaft 22 and the second rotating shaft 39 to rotate simultaneously through the connecting shaft 5 and the belt 51. When the first rotating shaft 22 rotates, it rotates the swing plate 23 and the push block 24, so that the push block 24 can be movably inserted into one of the movable slots 21. At this time, as the push block 24 rotates, it will push the groove wheel 2 to rotate. As the push block 24 rotates with the swing plate 23, it will be continuously inserted into the next movable slot 21, intermittently and continuously pushing the groove wheel 2 to rotate, so that the groove wheel 2 drives the drive shaft 13 to rotate intermittently. The turntable 17 fixed at the bottom of the drive shaft 13 is subjected to intermittent rotation. The discharge hole 18 on the turntable 17 will intermittently correspond to the first discharge hole 19 on the fixed plate 16, so that the material entering the feeding hopper 12 is intermittently discharged through the discharge hole 18 and the first discharge hole 19, avoiding the dense particle density caused by a large amount of material being discharged at once, which would affect the subsequent dust removal.

[0047] When the drive shaft 13 rotates, the dispersing block 14 fixed on the drive shaft 13 will rotate. When the agglomerated particles enter the feed hopper 12, since the dispersing block 14 and the inner wall of the feed hopper 12 form a discharge port 141, particles of the appropriate size fall down. The agglomerated raw material particles will pass between the dispersing block 14 and the inner wall of the feed hopper 12, and the round protrusion 15 will break up the agglomerated raw material particles, so as to avoid the raw material particles from accumulating together and causing the dust to not be separated in time.

[0048] After being fed, the raw material enters the dust collector 3 through the bottom of the feeding hopper 12 and falls onto the horizontal plate 31. The rotation of the second rotating shaft 39 drives the swing rod 4 to rotate. One end of the swing rod 4 is pre-selected to abut against one side of the inner wall of the rectangular groove 37, driving the moving plate 36 away from the dust collector 3. Then, the end adjacent to the previous swing rod 4 will contact the other side of the rectangular groove 37, thus pushing the moving plate 36 closer to the dust collector 3. Through the above operations, the second rotating shaft 39 drives the swing rod 4 to drive the moving plate 36 to move back and forth repeatedly. Through the push block 24, the horizontal plate 31 is pushed to move back and forth repeatedly, so that the horizontal plate 31 moves continuously, allowing the material falling onto the horizontal plate 31 to pass through different second rows. As the material falls through the feed hole 32, it disperses through the horizontal plate 31. At this time, the air blown by the fan 43 blows away impurities or dust, separating them. Through the above steps, all the granular materials are separated, increasing the gap between the material and the dust. This allows the fan 43 to better separate the dust from the material. The dust is blown by the fan 43 onto the electrostatic adsorption membrane 46 installed on the fixed frame 45 for adsorption, ultimately achieving the purpose of separating dust from granules and completing the dust removal effect. Subsequently, the material is poured into the packaging belt through the filling pipe 11. Through the above operations, the purpose of dust removal of granules is achieved during the material feeding process, improving the quality of raw materials leaving the factory and improving the finished product effect.

[0049] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
