Description

Technical Field

[0001] This utility model belongs to the technical field of bagging equipment, specifically relating to a plastic granule bagging equipment. Background Technology

[0002] The production of plastic products typically uses plastic granules as raw materials. These granules are melted by heating, poured into molds, and then cooled to solidify. Plastic granules not only allow for high-density storage but also facilitate transportation, significantly reducing warehousing and transportation costs. After production, the plastic granules need to be packaged. Currently, packaging plastic granules is generally done manually, requiring at least one operator to keep the bag open to ensure the granules flow accurately and smoothly into the packaging bag. During this process, the bag opening must be kept open for a certain period, increasing the operator's workload and exposing them to dust that can negatively impact their health. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a plastic granule bagging device to solve the technical problem of increased labor intensity caused by manually maintaining the bag opening in the open state in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A plastic granule bagging device includes a support frame with a bagging space formed within it. A bagging structure is located at the top of the bagging space. The bagging structure includes a mouth-supporting assembly and a clamping assembly that cooperates with the mouth-supporting assembly. The bagging structure also includes a dust-collecting assembly for dust removal. The mouth-supporting assembly includes a hollow support ring. An annular partition is provided between the inner and outer walls of the support ring, horizontally dividing the internal space of the support ring into an inner cavity and an outer cavity. Multiple limiting cylinders are connected to the outer surface of the support ring. The sliding seal connection includes a sliding column, a first spring between the sliding column and the partition plate, and a water inlet and outlet hole communicating with the outer cavity on the support ring. The water inlet hole is connected to a piston pump. The clamping assembly includes a connecting sleeve located above the limiting cylinder and extending in the same direction as the limiting cylinder. A connecting block is slidably connected inside the connecting sleeve. A second spring is provided between the connecting block and the bottom plate of the connecting sleeve. An "L"-shaped extension rod is rotatably connected to the side of the connecting block away from the second spring. A clamping block adapted to the contact block is provided on the free end of the vertical section of the extension rod.

[0006] Furthermore, a contact block is provided on the outer end face of the sliding column. The bottom surface of the contact block is circular, and the diameter of the bottom surface is consistent with the outer diameter of the limiting cylinder. The side surface of the contact block is arc-shaped.

[0007] Furthermore, the connecting sleeve is hollow inside, with an opening at one end opposite to the support ring;

[0008] Furthermore, a rotating groove is provided on the outer side of the connecting block away from the second spring, and a rotating protrusion adapted to the rotating groove is provided on the side of the extension rod facing the connecting block, with the rotating protrusion located inside the rotating groove.

[0009] Furthermore, the horizontal section of the extension rod and the connecting sleeve are in frictional contact;

[0010] Furthermore, the water inlet is located on the top surface of the support ring, and the water outlet is located on the bottom surface of the support ring;

[0011] Furthermore, the dust collection component includes a dust collection hole opened on the inner side of the support ring, which is connected to the inner cavity. An air extraction hole is also opened on the bottom surface of the support ring, and an exhaust fan is connected to the air extraction hole.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) Compared with the existing technology, the bag opening can be opened quickly by the opening support component, and the bag opening can be continuously supported to ensure that the bag opening is always in an open state during the filling process. This replaces manual operation, reduces labor intensity and improves production efficiency.

[0014] (2) By setting up a pressing component, the pressing block and the contact block are pressed tightly together and the opening of the packaging bag between them is pressed and fixed, thereby effectively preventing the packaging bag from separating from the contact block.

Detailed Implementation

[0022] Example 1, specifically as follows Figures 1-4 As shown.

[0023] A plastic pellet bagging device includes a support frame 1, a bagging space is formed inside the support frame 1, a bagging structure 3 is provided at the top of the bagging space, and support structures 7 are provided on both sides of the bagging space. The bagging structure 3 includes a mouth support assembly 4 and a pressing assembly 5 that cooperates with the mouth support assembly 4. The bagging structure 3 also includes a dust suction assembly 6 for dust removal.

[0024] like Figure 1 As shown, the support frame 1 has a rectangular parallelepiped structure, with a top plate 101 and a bottom plate 102 at its top and bottom, respectively, and side plates 103 on both sides along its length. The support frame 1 has a bagging space with openings on both sides.

[0025] A feed hopper 2 is connected to the center of the top plate 101. The feed hopper 2 includes a feed section above the top plate 101 and an extension section above the top plate 101. The support assembly 4 includes a support ring 401 located directly below the feed hopper 2. The support ring 401 is circular in shape, and its axis coincides with the axis of the extension section of the feed hopper 2. Multiple fixing rods 410 are welded between the top surface of the support ring 401 and the top plate 101 to fix the support ring 401. The support ring 401 is hollow inside. An annular partition 402, coaxial with the support ring 401, is provided between the inner and outer side walls. It is worth describing in detail that the distance between the partition 402 and the inner and outer side walls of the support ring 401 is equal. The annular partition 402 divides the internal space of the support ring 401 horizontally into an inner cavity 403 and an outer cavity 404.

[0026] Multiple horizontally oriented limiting cylinders 405 are connected along the circumferential direction on the outer surface of the support ring 401. The cylindrical limiting cylinders 405 are open at both ends and hollow inside. There is a gap between the inner end of the limiting cylinder 405 and the partition plate 402. A sliding column 406 is slidably and sealed inside the limiting cylinder 405. The sliding seal connection can use an O-ring, which is existing technology and will not be described in detail here. The length of the sliding column 406 is less than the length of the limiting cylinder 405. In the initial state, the outer end face of the sliding column 406 is flush with the outer end face of the limiting cylinder 405. A first spring 407 is provided between the sliding column 406 and the partition plate 402 to achieve an elastic connection between the two. Specifically, the first spring 407 is horizontal, and its inner and outer ends are welded and fixed to the partition plate 402 and the sliding column 406, respectively.

[0027] A contact block 408 is integrally formed on the outer end face of the sliding column 406. The bottom surface of the contact block 408 is circular, and its diameter is the same as the outer diameter of the limiting cylinder 405. The side surface of the contact block 408 is arc-shaped. By setting the contact block 408, on the one hand, the inward sliding of the sliding column 406 is limited; on the other hand, the arc-shaped side surface can not only increase the contact area but also reduce local stress peaks and prevent stress concentration.

[0028] The support ring 401 has a water inlet hole 409, which is connected to the outer cavity 404. In this embodiment, the water inlet hole 409 is located on the top surface of the support ring 401 and is connected to a piston pump (not shown in the figure). Water is injected into the outer cavity 404 through the piston pump. The support ring 401 has a water outlet hole (not shown in the figure) on the bottom surface, which is also connected to the outer cavity 404. A sealing plug (not shown in the figure) is provided on the water outlet hole, which is used to open and close the water outlet hole.

[0029] In use, firstly, the opening of the packaging bag is placed around the support ring 401. Then, the piston pump is turned on, and pressurized water enters the outer cavity 404 to form hydraulic pressure. Under the action of hydraulic pressure, the sliding column 406 slides outward. At this time, the first spring 407 is stretched, and the contact block 408 moves synchronously with the sliding column 406 and abuts against the inner side of the packaging bag opening. Under the combined action of multiple contact blocks 408 around the perimeter, the packaging bag opening is fully opened. After the packaging bag is filled, the piston pump is turned off and the water outlet is opened. The hydraulic pressure in the outer cavity 404 dissipates, the first spring 407 rebounds, and drives the sliding column 406 and contact block 408 to retract, completing a single opening process. The opening-opening assembly 4 can not only quickly open the bag opening, but also apply continuous action to the bag opening, ensuring that the bag opening remains open throughout the filling process. This replaces manual operation, reduces labor intensity, and improves production efficiency.

[0030] After the bag opening is opened by the mouth support assembly 4, it tensions the bag opening with a horizontal outward force, thereby preventing the bag opening from detaching from the mouth support assembly 4. However, in actual use, the combined effects of the impact force generated during the falling plastic granules, the deformation of the packaging bag itself, and the low friction between the packaging bag and the contact block 408 make it easy for the bag opening to detach from the mouth support assembly 4, resulting in leakage of plastic granules and interruption of the entire packaging process.

[0031] In this regard, the bagging structure 3 also includes a clamping assembly 5 used in conjunction with the spout assembly 4, such as... Figure 2 As shown, the clamping assembly 5 includes a connecting sleeve 502 positioned above and extending in the same direction as the limiting cylinder 405. The connecting sleeve 502 and the limiting cylinder 405 are connected by a fixing block 501. Specifically, the bottom surface of the fixing block 501 is welded to the top surface of the limiting cylinder 405, and the top surface of the fixing block 501 is welded to the bottom surface of the connecting sleeve 502. Notably, the connecting sleeve 502 is hollow inside, with an opening at one end opposite to the support ring 401. A cylindrical connecting block 503 is slidably connected inside the connecting sleeve 502, and a second spring 504 is provided between the connecting block 503 and the bottom plate of the connecting sleeve 502, thereby achieving an elastic connection between the two.

[0032] An extension rod 506 is rotatably connected to the side of the connecting block 503 facing away from the second spring 504. Specifically, a rotating groove 505 is formed on the outer surface of the connecting block 503 facing away from the second spring 504. A rotating protrusion 507 adapted to the rotating groove 505 is welded to the side of the extension rod 506 facing the connecting block 503. The rotating protrusion 507 is located within the rotating groove 505. The connecting block 503 and the extension rod 506 can move synchronously along the axial direction and can also rotate relative to each other around the axis.

[0033] It is worth explaining in detail that, in this embodiment, the extension rod 506 is L-shaped, with its horizontal section extending into the connecting sleeve 502 and rotatably connected to the connecting block 503. A clamping block 508, adapted to the contact block 408, is fixedly connected to the free end of its vertical section. The clamping block 508 faces the contact block 408 directly, and the side of the clamping block 508 facing the contact block 408 is curved. It is important to emphasize that, in this embodiment, the horizontal section of the extension rod 506 and the connecting sleeve 502 are in frictional contact, but relative movement and rotation are possible between them. That is, the extension rod 506 can rotate to any angle and remain suspended. Furthermore, in the initial state, the clamping block 508 is located inside the contact block 408.

[0034] In use, first, rotate the extension rod 506 so that the vertical section of the extension rod 506 is vertically upward to prevent it from affecting the opening of the bag. Then, adjust the opening support assembly 4 to open the bag opening. Finally, pull the pressing block 508 horizontally and rotate it until the pressing block 508 is directly opposite the contact block 408. During this process, the second spring 504 is stretched, releasing the pressing block 508. Under the rebound action of the second spring 504, the pressing block 508 and the contact block 408 are pressed tightly together, and the bag opening between them is pressed and fixed, thereby effectively preventing the bag from separating from the contact block 408.

[0035] During the filling process, dust from the plastic granules inevitably disperses. To address this, a dust-absorbing component 6 is installed on the support ring 401. Figure 2 As shown, the dust collection component 6 includes dust collection holes 601 formed on the inner side of the support ring 401. The dust collection holes 601 are evenly distributed along the circumference and communicate with the inner cavity 403. An exhaust hole 602 is also formed on the bottom surface of the support ring 401, and an exhaust fan is connected to the exhaust hole 602. In use, when the exhaust fan is turned on, dust that has drifted to the bag opening is drawn into the inner cavity 403 through the dust collection holes 601 by the exhaust fan, and then discharged through the exhaust hole 602 by the airflow. This achieves dust removal and collection, reduces dust dispersion, improves the cleanliness of the working environment, and protects the health of operators.

[0036] The support structure 7 includes a vertical support plate 701. The contact surface of the support plate 701 facing the packaging bag is an arc surface to increase the contact area with the packaging bag. Multiple support rods 702 are welded to the fixed surface of the support plate 701 facing away from the packaging bag. In this embodiment, there are 4 support rods 702 distributed at the top corner of the fixed surface. The support rods 702 penetrate the side plate 103 and are slidably connected to the side plate 103. The support plate 701 is supported by the support rods 702. A connecting ring is welded to the free end of the support rod 702. The support rods 702 form a whole through the connecting ring.

[0037] A horizontal adjusting rod 703 is threaded onto the side plate 103. The free end of the adjusting rod 703 is directly opposite the center of the fixed surface of the support plate 701, and the adjusting rod 703 abuts against the support plate 701. The depth of the support plate 701 can be adjusted by the adjusting rod 703 to accommodate different types of packaging bags. By setting up the support structure 7, the packaging bag can be effectively prevented from tipping over during the filling process, ensuring the smooth progress of the filling process.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
