Description

Technical Field

[0001] This invention relates to the technical field of packaging machinery, and in particular to a solid plasticizer filling machine. Background Technology

[0002] In the plastics industry, plasticizers are an indispensable additive. They can increase the flexibility and processability of plastic materials and are widely used in the manufacturing process of plastic products such as PVC (polyvinyl chloride). Plasticizers come in both liquid and solid forms. Solid plasticizers are more popular in certain specific applications because they are easy to store, transport, and do not easily volatilize during use.

[0003] After processing, plasticizer granules need to be packaged for convenient transportation and storage. The common packaging method is to use a filling machine to feed the plasticizer granules into the packaging can for storage. The feed pipe on the filling machine is inserted downward into the packaging can on the conveyor belt, and the plasticizer granules fall into the packaging can through the feed pipe. However, this packaging method cannot accurately control the packaging amount of plasticizer granules, so it cannot achieve quantitative packaging of plasticizers. At the same time, the material filling speed is slow and the packaging time is relatively long. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a solid plasticizer filling machine, the specific technical solution of which is as follows:

[0005] A solid plasticizer filling machine includes a vertical cylinder, a cap, a feed pipe, a top plate, and a bottom plate. The vertical cylinder is vertical, and the cap is installed at the bottom of the vertical cylinder. The cap is used to seal the top of the packaging can during filling. The feed pipe is connected to the vertical cylinder and is used to feed plasticizer granules into the vertical cylinder. The top plate and the bottom plate are distributed vertically and are both located inside the vertical cylinder. The space between the top plate and the bottom plate is used to quantitatively measure the plasticizer granules. A column is vertically arranged on the bottom plate, and the top of the column passes through the top plate and is slidably connected to it.

[0006] Furthermore, the chassis is tilted, and the top plate and the column rotate along the axis of the vertical cylinder.

[0007] Furthermore, a baffle is provided on the top of the top plate. When the top plate moves downward inside the vertical cylinder, the baffle blocks the output end of the feed pipe.

[0008] Furthermore, the chassis is provided with two levers, which are coplanar with the column, and the planes on which the two levers are located are perpendicular to the plane of the chassis. The top of the lever passes through the top plate and slides into the baffle.

[0009] Furthermore, a support rolls on the outer wall of the vertical cylinder, and the top of the column slides through the support. Two limiting discs are provided on the column, both of which are located above the vertical cylinder and on the upper and lower sides of the support, respectively. One limiting disc is connected to the support by a first spring.

[0010] Furthermore, a support ring is provided on the inner wall of the baffle, the baffle rotates on the support ring, and two vertical plates and a first threaded rod are provided on the support ring. The two vertical plates are distributed on the front and rear sides of the column, the first threaded rod is located between the two vertical plates, and the first threaded rod rotates on the support ring. A transmission wheel is provided on the first threaded rod, and the transmission wheel is connected to the inner wall of the baffle. A threaded sleeve is screwed onto the first threaded rod, and the position of the threaded sleeve is fixed.

[0011] Furthermore, two sliders are disposed opposite each other on the outer wall of the vertical cylinder;

[0012] It also includes a top plate, on which two side plates are provided. The two side plates are respectively connected to two sliders. The vertical cylinder slides vertically on the sliders. A connecting plate is fixed at the top of each vertical plate. The two connecting plates slide on the two side plates respectively. A second threaded rod is screwed through the connecting plate. The second threaded rod is rotatably installed on the top plate. The connecting plate and the vertical cylinder are connected by a second spring.

[0013] The top plate has a rolling conveyor pipe, the bottom of which slides into the feed pipe, and the threaded sleeve is fixed to the top plate.

[0014] Furthermore, a motor is provided on the top plate, and a worm is provided at the output end of the motor. Two worm wheels mesh on the worm, and the two worm wheels are respectively connected to two second threaded rods for transmission.

[0015] The advantages of this invention are:

[0016] The fixed volume space between the top and bottom plates ensures consistent filling volume for each batch of plasticizer granules, improving packaging accuracy and reducing resource waste and post-processing complexity caused by uneven packaging. The top plate's downward movement and material compression method quickly squeezes the measured amount of plasticizer granules into the packaging can, significantly shortening the filling time and improving overall production line efficiency. The capping seals the top of the packaging can during filling, effectively preventing plasticizer granules from scattering during high-speed filling and reducing dust pollution in the production environment. The bottom plate not only participates in the metering process but also diffuses the material as it enters the packaging can, ensuring even distribution of plasticizer granules and preventing can opening blockage due to material accumulation. In summary, this innovative plasticizer granule packaging and filling machine not only solves many drawbacks of traditional filling methods, such as inaccurate packaging volume, slow filling speed, material accumulation, and environmental pollution, but also greatly improves production efficiency and working environment safety through its high precision, high efficiency, and high degree of automation.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0028] like Figures 1 to 6 As shown, a solid plasticizer filling machine of the present invention includes a vertical cylinder 1, a cap 2, a feed pipe 3, a top plate 4, and a bottom plate 5. The vertical cylinder 1 is vertical, the cap 2 is installed at the bottom of the vertical cylinder 1, and the cap 2 is used to seal the top of the packaging can during filling. The feed pipe 3 is connected to the vertical cylinder 1 and is used to feed plasticizer granules into the vertical cylinder 1. The top plate 4 and the bottom plate 5 are distributed vertically and are both located inside the vertical cylinder 1. The space between the top plate 4 and the bottom plate 5 is used for metering the plasticizer granules. A column 6 is vertically arranged on the bottom plate 5, and the top of the column 6 passes through the top plate 4 and is slidably connected to it.

[0029] In detail, the vertical cylinder 1 is vertical, and the pressure cap 2 is installed at the bottom of the vertical cylinder 1. The opening at the bottom of the vertical cylinder 1 is used to discharge plasticizer particles into the packaging can during filling. The pressure cap 2 is used to seal the top of the packaging can, thereby preventing the plasticizer particles from flying around due to airflow during filling. The feed pipe 3 is fixed to the outer wall of the vertical cylinder 1 and is interconnected with the vertical cylinder 1. The top plate 4 and the bottom plate 5 are both vertically slidably installed inside the vertical cylinder 1. The column 6 is used to connect and support the top plate 4 and the bottom plate 5. When filling is required, the packaging can is conveyed to the area below the pressure cap 2 by an external conveyor belt, pushing the vertical cylinder 1 downward. The pressure cap 2 seals the top opening of the packaging can, and the bottom opening of the vertical cylinder 1 is inserted into the upper part of the packaging can. The plasticizer particles are introduced into the top of the vertical cylinder 1 through the feed pipe 3. Between the top plate 4 and the bottom plate 5, since the size of the space between the top plate 4 and the bottom plate 5 remains constant, the amount of plasticizer granules stored in this space is a predetermined value. Thus, the material is quantitatively processed through the top plate 4 and the bottom plate 5. When the plasticizer granules fill the space between the top plate 4 and the bottom plate 5, the top plate 4 moves down and pushes the bottom plate 5 down synchronously with the help of the filled plasticizer granules, thereby conveying the quantitative material downward. When the bottom plate 5 moves out of the vertical cylinder 1 and is located inside the packaging can, the plasticizer granules between the top plate 4 and the bottom plate 5 fall into the packaging can, thereby realizing the filling operation. Because the top plate 4 squeezes the quantitative material, it causes the top plate 4 to quickly squeeze the material out of the vertical cylinder 1, realizing a rapid filling operation mode. Due to the sealing effect of the cap 2, the rapidly moving material will not fly out of the packaging can.

[0030] It should be noted that since the material is scattered into the packaging can through the base 5, the base 5 can spread the material to the sides of the packaging can, so that the material is evenly scattered and the material is prevented from accumulating at the mouth of the packaging can and blocking the mouth.

[0031] The fixed volume space between the top plate 4 and the bottom plate 5 ensures consistent filling volume for each batch, improving packaging accuracy and reducing resource waste and post-processing complexity caused by uneven packaging. The top plate 4 moves downwards and squeezes the material, quickly injecting a fixed amount of plasticizer granules into the packaging can, significantly shortening the filling time and improving overall production line efficiency. The cap 2 seals the top of the packaging can during filling, effectively preventing plasticizer granules from scattering during high-speed filling and reducing dust pollution in the production environment. The bottom plate 5 not only participates in the quantitative process but also diffuses the material as it enters the packaging can, ensuring even distribution of plasticizer granules and preventing can opening blockage caused by material accumulation. In summary, this innovative plasticizer granule packaging and filling machine not only solves many drawbacks of traditional filling methods, such as inaccurate packaging volume, slow filling speed, material accumulation, and environmental pollution, but also greatly improves production efficiency and working environment safety through its high precision, high efficiency, and high degree of automation.

[0032] Furthermore, the chassis 5 is tilted, and the top plate 4 and the column 6 rotate along the axis of the vertical cylinder 1.

[0033] In detail, due to the tilt of the chassis 5, when the chassis 5 is moved into the packaging can, the top plate 4 squeezes the material and guides it into the packaging can along the inclined surface of the chassis 5. At this time, the chassis 5 performs directional conveying of the material. Since the top plate 4 and the column 6 rotate, the chassis 5 can rotate synchronously. At this time, the chassis 5 can perform rotating and dispersing treatment of the material into the packaging can, so that the material is quickly and evenly dispersed into the packaging can. Furthermore, due to the tilt of the chassis 5, no material will remain on the chassis 5, thereby improving the quantitative filling accuracy.

[0034] Furthermore, a baffle 7 is provided on the top of the top plate 4. When the top plate 4 moves downward inside the vertical cylinder 1, the baffle 7 blocks the output end of the feed pipe 3.

[0035] In detail, by setting the baffle 7, when the top plate 4 squeezes a certain amount of material downward into the packaging can, the baffle 7 blocks the output end of the feed pipe 3, thereby preventing the material from flowing to the top plate 4 through the feed pipe 3.

[0036] Furthermore, the chassis 5 is provided with two lever plates 8, the two lever plates 8 and the column 6 are coplanar, and the plane of the two lever plates 8 is perpendicular to the plane of the chassis 5. The top of the lever plate 8 passes through the top plate 4 and slides into the baffle 7.

[0037] In detail, by setting the lever plate 8, the column 6 and the base plate 5 can be driven to rotate synchronously when the top plate 4 rotates, so that there is no need to set rotation power for both the top plate 4 and the base plate 5. Since the planes where the two lever plates 8 are located are perpendicular to the plane where the base plate 5 is located, the material on the base plate 5 can be smoothly discharged through the inclined surface of the base plate 5, and the lever plate 8 will not obstruct the material.

[0038] When the feed pipe 3 introduces the material between the top plate 4 and the bottom plate 5, the top plate 4 can be rotated. At this time, the two baffles 8 rotate, thereby using the two baffles 8 to evenly fill the space between the top plate 4 and the bottom plate 5 with the material, thus improving the quantitative accuracy of the material.

[0039] Furthermore, a support 9 rolls on the outer wall of the vertical cylinder 1, and the top of the column 6 slides through the support 9. Two limiting discs 10 are provided on the column 6. Both limiting discs 10 are located above the vertical cylinder 1, and the two limiting discs 10 are located on the upper and lower sides of the support 9, respectively. One limiting disc 10 is connected to the support 9 by a first spring 11.

[0040] In detail, the first spring 11 provides an upward elastic thrust to the column 6 through its upper limit plate 10, and the limit plate 10 is rotatably connected to the column 6. When the top plate 4 squeezes the material and moves downward, the bottom plate 5 and the column 6 move downward synchronously. At this time, the column 6 slides on the support 9, and the first spring 11 undergoes elastic deformation. When the bottom plate 5 moves out to below the vertical cylinder 1, the material is discharged. At this time, due to the elastic action of the first spring 11, the bottom plate 5 is kept in the position near the mouth of the packaging can, thereby preventing the bottom plate 5 from falling naturally and causing the material to bury the bottom plate 5.

[0041] After the material is discharged, the top plate 4 contacts the bottom plate 5. At this time, the top plate 4 moves upward in the opposite direction. Due to the action of the first spring 11, the bottom plate 5 moves upward synchronously. When the bottom plate 5 enters the lower side of the vertical cylinder 1, the limiting plate 10 located below the support 9 contacts the support 9. At this time, the bottom plate 5 and the column 6 no longer move, thus positioning the bottom plate 5. The top plate 4 can continue to move.

[0042] In actual use, since the movement range of the chassis 5 is limited by the limiting plate 10, the material quantity can be adjusted simply by adjusting the position of the top plate 4 inside the vertical cylinder 1.

[0043] Furthermore, a support ring 12 is provided on the inner wall of the baffle 7, and the baffle 7 rotates on the support ring 12. Two vertical plates 13 and a first threaded rod 14 are provided on the support ring 12. The two vertical plates 13 are distributed on the front and rear sides of the column 6. The first threaded rod 14 is located between the two vertical plates 13 and rotates on the support ring 12. A transmission wheel 15 is provided on the first threaded rod 14, and the transmission wheel 15 is connected to the inner wall of the baffle 7. A threaded sleeve 16 is screwed onto the first threaded rod 14, and the position of the threaded sleeve 16 is fixed.

[0044] In detail, since the position of the threaded sleeve 16 is fixed, when the first threaded rod 14 moves up and down, the first threaded rod 14 will rotate on the threaded sleeve 16. During the filling operation, it pushes the two vertical plates 13 to move down. The two vertical plates 13 push the baffle 7 to move down through the support ring 12. The baffle 7 drives the top plate 4 to move down. At this time, the support ring 12 will drive the first threaded rod 14 to move down and down on the threaded sleeve 16. The first threaded rod 14 rotates synchronously. The first threaded rod 14 drives the baffle 7 to rotate through the transmission wheel 15, thereby causing the top plate 4 and the baffle 7 to rotate while moving down.

[0045] The above-mentioned structure can realize the vertical movement and rotation of the top plate 4 and the baffle 7 by the single movement of the vertical plate 13, and it can drive the chassis 5 to move and rotate within a specified range, thereby realizing multiple motion operations by switching from a single motion mode, without the need to set up a separate power source, control structure and other complex structures for each motion. Its operation is simple and its functionality is strong.

[0046] Furthermore, two sliders 19 are arranged opposite each other on the outer wall of the vertical cylinder 1;

[0047] It also includes a top plate 17, on which two side plates 18 are provided. The two side plates 18 are respectively connected to two sliders 19. The vertical cylinder 1 slides vertically on the sliders 19. Each of the vertical plates 13 has a connecting plate 20 fixed at the top. The two connecting plates 20 slide on the two side plates 18 respectively. A second threaded rod 21 is screwed through the connecting plate 20. The second threaded rod 21 is rotatably installed on the top plate 17. The connecting plate 20 and the vertical cylinder 1 are connected by a second spring 22.

[0048] The top plate 17 has a conveying pipe 23 that rolls on it. The bottom of the conveying pipe 23 slides into the feed pipe 3, and the threaded sleeve 16 is fixed on the top plate 17.

[0049] In detail, the second spring 22 provides elastic tension to the vertical cylinder 1. When filling is required, the second threaded rod 21 is rotated, and the second threaded rod 21 pushes the connecting plate 20 to move down. The connecting plate 20 drives the vertical cylinder 1 to move down synchronously through the second spring 22. The vertical cylinder 1 slides on the slider 19. When the cap 2 contacts the packaging can, the cap 2 and the vertical cylinder 1 stop moving. At this time, the connecting plate 20 continues to move down and pushes the vertical plate 13 to move down relative to the vertical cylinder 1, thereby providing power supply to both the vertical cylinder 1 and the vertical plate 13.

[0050] When the feed pipe 3 moves, it slides relative to the conveying pipe 23, and the feed pipe 3 and the conveying pipe 23 remain in communication.

[0051] Furthermore, a motor 24 is provided on the top plate 17, and a worm gear 25 is provided at the output end of the motor 24. Two worm wheels 26 are meshed on the worm gear 25, and the two worm wheels 26 are respectively connected to two second threaded rods 21 for transmission.

[0052] In detail, the motor 24 can power the two second threaded rods 21 via the worm 25 and two worm gears 26.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
