Description

Extruder lifting device, equipment and system

[0001] This patent application claims priority to the following Chinese patent application:

[0002] Submission Date: August 2, 2024; Application Number: 2024110612737; Invention Title: Extruder Lifting Device, Equipment and System;

[0003] The full text of the above application is incorporated herein by reference. Technical Field

[0004] This invention relates to the field of logistics and transportation, and in particular to a pusher lifting device, equipment and system. Background Technology

[0005] For the storage, transportation, filling, and discharge of viscous liquids, there are many liquid storage and transportation devices on the market. Among them, the mainstream storage and transportation devices are: medium bulk containers (IBCs) used in combination with liners.

[0006] An IBC (Internal Blouse) typically includes four side panels, a top cover, and a base; the liner typically includes a filling port, a discharge port, and the liner body. The IBC has a discharge port at the bottom, which is connected and fixed to the liner discharge port. Discharge begins by opening the liner discharge port valve. However, in discharging viscous liquids, the liquid discharge is slow and inefficient; after discharge, a large amount of liquid remains in the liner bag, resulting in wasted costs. Existing extruders include a pair of extruders and a drive unit. The pair of extruders are configured to operably clamp the object between them, and while the pair of extruders moves relative to the object, they apply a pushing force to the object. The drive unit is associated with the pair of extruders and can drive at least one of the extruders relative to the other, achieving efficient discharge of viscous liquid from the liner. However, when used with an IBC and liner, the extruder needs to be installed on top of both the IBC and liner. Due to weight and other limitations, manual handling increases labor intensity and affects work efficiency. Summary of the Invention

[0076] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0077] The first embodiment of the present invention relates to a pusher lifting device 100. As shown in Figures 1, 2, and 3, the pusher lifting system 400 includes: a container 410, an inner liner bag 420, a pusher lifting device 100, and a pusher 310. The pusher lifting device 100 is used to lift the pusher 310. The inner liner bag 420 is placed in the container 410. The top of the inner liner bag 420 has a filling port 421, and the bottom of the inner liner bag 420 has a discharge port 423. The pusher 310 has a pair of hinged clamping arms 311 and a power member 312. Each clamping arm 311 has a roller 3111 driven to rotate by the power member 312, and an outer cover 3112 for mounting the roller 3111. The pair of rollers 3111 cooperate to clamp the inner liner bag 420 and can apply a pushing force to the inner liner bag 420 by reversing their relative positions.

[0078] As shown in Figures 4 and 5, the extruder lifting device 100 includes: a base 1, a support frame 2, a transmission assembly 3, a reel assembly 4, and a drive component 5. The support frame 2 is mounted on the base 1, and the transmission assembly 3 is mounted on the support frame 2. The reel assembly 4 includes: a take-up shaft 41 connected to the transmission assembly 3, and a lifting component 42 wound around the take-up shaft 41. The drive component 5 is used to drive the transmission assembly 3 to drive the take-up shaft 41 to wind up or unwind the lifting component 42. The lifting component 42 consists of a pull rope 421 and a hook 422 located at the bottom of the stretching mechanism. The hook 422 hooks onto the extruder 310, the take-up shaft 41 winds up the pull rope 421, and the lifting component 42 raises the extruder 310, allowing the extruder 310 to be raised to the opening of the container 410, so that the extruder 310 can clamp the inner liner bag 420. In one embodiment, the lifting component 42 may not include a hook and can be directly attached to the extruder 310. The support frame 2 extends to support the container 410. The drive component 5 drives the transmission assembly 3. The transmission assembly 3 causes the take-up shaft 41 to wind up the lifting component 42. The lifting component 42 lifts the extruder 310. The take-up shaft 41 releases the lifting component 42, and the lifting component 42 lowers the extruder 310. This eliminates the need for manual lifting of the extruder, making it easier to install the extruder, improving work efficiency, and also meeting the requirements of some environments where the extruder is too heavy to be installed manually.

[0079] The extruder lifting device 100 has an unlocked state (as shown in Figure 9) and a self-locking state (as shown in Figure 8). When the extruder lifting device 100 is in the unlocked state, the lifting member 42 can be released from the winding shaft 41 under the action of external force; when the extruder lifting device 100 is in the self-locking state, the drive member 5 drives the transmission assembly 3 to make the winding shaft 41 wind up the lifting member 42. That is to say, in the unlocked state, the extruder 310 is only subjected to gravity in the vertical direction and can fall freely. The drive member 5 is not related to the extruder 310, and the operation of the drive member 5 will not have any effect on the extruder 310. When the extruder 310 extrudes the inner liner bag 420, the liquid level in the inner liner bag 420 gradually decreases with the extrusion process. The extruder 310 itself has its own weight and is always located on the inner liner bag 420. The extruded liquid also decreases with the liquid level. Understandably, in some embodiments, the pusher 310 can also be driven to descend by a driver. However, during the descent of the pusher 310 by the driving member 5 inside the pusher 310 pushing the inner liner bag 420, the descent speed of the pusher 310 must match the descent speed of the liquid level, that is, match the speed at which the pusher 310 pushes the liquid inside the inner liner bag 420. In the self-locking state, the driving member 5 is associated with the pusher 310, and the drive transmission assembly 3 lifts or lowers the pusher 310 to prevent the pusher 310 from suddenly falling.

[0080] Further, as shown in Figures 1 and 3, the reel assembly 4 has a pair, and the lifting members 42 of the pair of reel assemblies 4 are respectively used to connect the two ends of the extruder 310 extending along the length direction. This makes the lifting of the extruder 310 more balanced. In some embodiments, the extruder 310 may be connected to one or more lifting members 42.

[0081] Further, as shown in Figure 5, the transmission assembly 3 includes: a transmission shaft 31 connected to the take-up shaft 41, a transmission chain 32 connected to the transmission shaft 31, and a clutch 33 connected to the transmission chain 32. The drive member 5 is used to drive the clutch 33. When the clutch 33 rotates, it drives the transmission chain 32. When the transmission chain 32 is in motion, it drives the transmission shaft 31. When the transmission shaft 31 rotates, it drives the take-up shaft 41 to rotate. As shown in Figure 8, the clutch 33 is rotatably connected to the support frame 2. When the clutch 33 rotates to the first position around its connection with the support frame 2, the extruder lifting device 100 is in a self-locking state, and the clutch 33 is engaged with the drive member 5. As shown in Figure 9, when the clutch 33 rotates to the second position around its connection with the support frame 2, the extruder lifting device 100 is in an unlocked state, and the clutch 33 is separated from the drive member 5. The extruder lifting device 100 also includes: an indexing pin 6 connected to the clutch 33. The indexing pin 6 is detachably connected to the support frame 2 and is used to position the clutch 33 in the first or second position.

[0082] Specifically, as shown in Figures 5, 6, and 7, the clutch 33 has a main body 331, a clutch gear 332, a bearing 333, a main shaft 334, and a sprocket 335. The main shaft 334 connects the bearing 333, the clutch gear 332, and the sprocket to the main body 331. The rotating shaft 30 and the indexing pin 6 connect the main body 331 to the support frame 2. When the indexing pin 6 is removed, the main body 331 can rotate around the rotating shaft to a first position or a second position. The drive member 5 has a drive gear 50. When the clutch 33 is in the first position, the clutch 33 is close to the drive member 5, and the clutch gear 332 meshes with the drive gear 50. The drive member 5 can drive the clutch 33, which drives the transmission chain 32 to drive the winding shaft 41 to rotate and the winding lifting member 42 to rotate. Remove the indexing pin 6 and rotate the clutch 33 around its connection with the support frame 2 by A° to the second position. Then connect the clutch 33 to the support frame 2 using the indexing pin 6. At this time, the clutch 33 is in the second position. The clutch 33 and the drive member 5 are far away from the clutch gear 332 and the drive gear 50. The drive member 5 cannot drive the clutch 33, so it cannot make the winding shaft 41 wind up or release the lifting member 42. In other words, at this time, the rise and fall of the extruder 310 is unrelated to the drive member 5.

[0083] In other embodiments, as shown in Figures 12 and 13, the extruder lifting device 500 may also lack a clutch 33. The drive component 5 includes a handwheel 51 and a reducer 52. The transmission chain 32 is connected to the reducer 52. The handwheel 51 drives the reducer, which in turn drives the transmission chain 32, causing the transmission chain 32 to drive the transmission shaft 31, thus rotating the take-up shaft 41. In this embodiment, before the extruder 310 is started, as shown in Figure 12, the lifting component 42 is separated from the extruder 310. At this time, the drive component 5 is not associated with the extruder 310, meaning the extruder lifting device 100 is in the unlocked state. The extruder 310 automatically sinks as the liquid in the inner liner bag 420 is discharged. During this process, the filling port fixing component 422 can be connected to the through port, and the tensioning component 8 can be connected to the horizontal extension 21. As the extruder 310 descends with the inner liner bag 420, the tensioning component 8 provides a corresponding pulling force to the inner liner bag 420. After discharge, as shown in Figure 13, the lifting member 42 is connected to the extruder 310. At this time, the driving member 5 is associated with the extruder 310, meaning the extruder lifting device 500 is in a self-locking state, and the lifting member 42 can lift the extruder 310. Therefore, in this embodiment, the unlocked state of the extruder lifting device 500 is when the lifting member 42 is separated from the extruder 310, and the self-locking state is when the lifting member 42 is connected to the extruder 310. In other words, by manually installing the lifting member 42 to connect to the extruder 310, both the unlocked and self-locking states are achieved.

[0084] In another embodiment, as shown in Figures 14, 15, 16, and 17, the extruder lifting device 600 does not have a clutch 33. The winding shaft 41 is driven by a hand-cranked sprocket and a ratchet 72, allowing the extruder lifting device 600 to have both an unlocked and a self-locking state. Specifically, in this embodiment, as shown in Figures 14 and 17, the driving component 5 includes a handwheel 51. One end of the transmission chain 32 is connected to the support frame 2 via a main shaft 34 and a bearing 35. The other end of the transmission chain 32 is connected to the drive shaft via a second sprocket 37. The handwheel 51 drives the main shaft 34, causing the first sprocket 36 to drive the transmission chain 32. The transmission chain 32 drives the second sprocket 37 to drive the drive shaft 31, causing the winding shaft 41 to rotate, allowing the winding shaft 41 to wind up the lifting component 42. As shown in Figures 15 and 16, the extruder lifting device 600 includes: a gear 72 fixed to the drive shaft 31 and a ratchet 72 hinged to the support frame 2. The ratchet 72 is used to rotate to engage with or disengage from the gear 71. When the ratchet 72 engages with the gear 71, the extruder lifting device 600 is in a self-locking state; when the ratchet 72 disengages from the gear 71, the extruder lifting device 600 is in an unlocked state. In use, to achieve the unlocked state, the ratchet 72 is manually moved to disengage from the gear 71; to achieve the unlocked state, the ratchet 72 is manually moved to engage with the gear 71.

[0085] Further, as shown in Figure 10, the support frame 2 includes: a horizontal extension 21 and a longitudinal extension 22 connected to the horizontal extension 21, the longitudinal extension 22 being connected to the base 1.

[0086] Additionally, as shown in Figures 5 and 10, the drive shaft 31 extends horizontally on the horizontal extension 21, and the clutch 33 is movably connected to the longitudinal extension 22. As shown in Figures 5 and 6, the longitudinal extension 22 has multiple positioning holes 220. At least one of the positioning holes 220 is used to separate the clutch 33 connected to the indexing pin 6 from the drive member 5 when the indexing pin 6 is inserted. At least one of the positioning holes 220 is used to engage the clutch 33 connected to the indexing pin 6 with the drive member 5 when the indexing pin 6 is inserted. Two horizontally spaced positioning holes 220 can be provided as shown in the figure.

[0087] Further, as shown in Figures 4 and 10, the horizontal extension 21 is spaced apart from the base 1 to form a placement area 13, and the longitudinal extension 22 is rotatably connected to the base 1. In use, as shown in Figure 10, the longitudinal extension 22 can be selected first, and the horizontal extension 21 can be positioned above the container 410. The lifting member 42 descends and connects to the extruder 310. After the extruder 310 is raised, the longitudinal extension 22 is rotated as shown in Figure 4, so that the horizontal extension 21, along with the extruder 310, is positioned above the container 410. At this time, the horizontal extension 21 is spaced apart from the base 1 to form the placement area 13. This facilitates the installation of the extruder 310 by the extruder lifting device 100 without interference from the container 410. As shown in Figure 11, the longitudinal extension 22 is connected to the base 1 via a rotating connector 9. The rotating connector 9 is connected from the top by at least a rotating shaft 91, a bearing 92, a shaft fixing member 93, and a shaft base 94. The rotating shaft 91 is rotatably connected to the shaft fixing member 93 via the bearing 92, thereby realizing the rotatable connection between the longitudinal extension 22 and the base 1. The shaft fixing member 93 is connected to the longitudinal extension 22 via a nut 95.

[0088] Further, as shown in Figures 4 and 10, the base 1 includes: a pair of relatively spaced-apart base rods 11, a connecting rod 12 connecting the pair of base rods 11, and a support frame 2 rotatably connected to the connecting rod 12. A container 410 for holding the inner liner bag 420 is located between the pair of base rods 11, and a pusher 310 is used to clamp and push the inner liner bag 420.
