Description

Technical Field

[0001] The utility model relates to the field of logistics transportation, and particularly relates to a fluid discharge system and a pusher thereof. Background Art

[0002] For the storage, transportation, filling and discharging of viscous liquids, there are many liquid storage and transportation devices on the market at present. These liquids are stored in sealed bags. After the discharge is completed, a large amount of liquid remains in the inner lining bag, resulting in cost waste. In order to reduce costs and waste of resources, a pusher is generally used during discharge to extrude the liquid in the liquid bag.

[0003] A relatively mature pusher on the market at present consists of a pusher member, a gearbox and a locking structure. The pusher member consists of two parts. The two pusher members are fixed on the gearbox and the rear base respectively, forming a pusher on each of the left and right sides. The left and right pushers are locked by a locking wrench. By rotating the locking wrench, the locking screw nut of the pusher member A is threadedly connected and tightened. At this time, the pusher can be powered on to cooperate with the liquid discharge. However, during the locking process of the locking screw and the nut, the axes are not on the same axis, the rotation of the locking wrench is not smooth, and the locking screw and the nut generate powder due to friction, affecting the service life of the pusher, increasing the cost and causing waste of resources.

[0058] Embodiments of the present utility model are described below with reference to the accompanying drawings.

[0059] An embodiment of the present utility model relates to a pusher 100. As Figure 1 , Figure 2 , Figure 3 shown, the pusher 100 includes: a first pusher member 1, a second pusher member 2, a first base 3, a second base 4, and a driving device 5. The first pusher member 1 includes: a first mounting frame 11, and a first roller 12 rotatably connected to the first mounting frame 11. One end of the second pusher member 2 is hinged to one end of the first pusher member 1; the second pusher member 2 includes: a second mounting frame 21, and a second roller 22 rotatably connected to the second mounting frame 21. The first base 3 is connected to the other end of the first pusher member 1, and the first base 3 includes: a first base body 31, an elastic body 32 disposed within the first base body 31, and a docking member 33. The first roller 12 is rotatably connected to the first base body 31, and the elastic body 32 abuts against one side of the docking member 33 facing the hinged connection end of the first pusher member 1 and the second pusher member 2, and applies a thrust to the docking member 33 in a direction away from the hinged connection end of the first pusher member 1 and the second pusher member 2. The second base 4 is connected to the other end of the second pusher member 2, and the second base 4 includes: a second base body 41, and a locking structure connected to the second base body 41. As Figure 4 , Figure 5 , Figure 6 , Figure 7 shown, the second roller 22 is rotatably connected to the second base body 41. The locking structure is detachably connected to the docking member 33, and the locking structure is used to insert into the docking member 33 to adjust the angle between the first pusher member 1 and the second pusher member 2, and when the locking structure is inserted into the docking member 33 to the locking position and locked with the docking member 33, the first roller 12 and the second roller 22 are clamped. The driving device 5 is used to drive the first roller 12 and the first roller 12 to rotate relative to each other.

[0060] As Figure 4 , Figure 5 , Figure 6 , Figure 7 shown, during the process of locking the locking structure with the docking member 33, the first pusher member 1 and the second pusher member 2 approach each other, the angle therebetween decreases, the axis of the docking member 33 follows the offset of the locking structure, the docking member 33 presses the elastic member 64, realizing the floating locking of the first base 3 and the second base 4, preventing powder from being generated due to friction between the docking member 33 and the locking structure, thereby facilitating the locking between the first base 3 and the second base 4, and prolonging the service life, reducing costs, and saving resources.

[0061] Specifically, the driving device 5 includes a motor, which can be located above, below or on the side of the first roller 12 and the second roller 22. The motor shaft is fixed through the mounting hole of the first gear and the first gear. During operation, the first gear drives the second gear to rotate. The second gear drives the first worm to rotate. The first worm drives the first worm gear to rotate. The first worm gear drives the second worm to rotate. The second worm drives the second worm gear to rotate. The second worm gear is connected to the axis of the first roller 12 and drives the first roller 12 to rotate accordingly. At the same time, the third gear connected to the first roller 12 also rotates and drives the fourth gear connected to the other second roller 22 to rotate. Thus, through the cooperation of the third gear and the fourth gear, the first roller 12 and the second roller 22 perform relative reverse movements. The first base 3 and the second base 4 are locked and close together, and the first roller 12 and the second roller 22 also come close together. The first roller 12 and the second roller 22 perform relative reverse movements. The inner lining bag has a specific discharge port, and the bag body of the inner lining bag is clamped between the first roller 12 and the second roller 22, so as to squeeze the liquid in the inner lining bag and make the liquid discharge from the discharge port.

[0062] Further, as Figure 3 and Figure 8 shown, the first base body 31 includes: a seat body portion 311 and a first cover plate 312. The seat body portion 311 is provided with a first card slot 313 for the elastomer 32 to be embedded, and a groove 314 for the docking member 33 to be embedded. The side of the seat body portion 311 facing the second base 4 is also provided with an insertion port communicating with the groove 314. The locking structure is used to insert the docking member 33 through the insertion port.

[0063] As Figure 3 、 Figure 5 shown, the first cover plate 312 has a support portion 310 inserted into the seat body portion 311. One end of the docking member 33 facing away from the second base 4 abuts against the support portion 310. The side of the docking member 33 facing the second base 4 and the side facing away from the elastomer 32 both abut against the wall surface of the groove 314. The docking member 33 is clamped by the cooperation of the support portion 310 and the wall surface of the groove 314, preventing the docking member 33 from being pushed away from the locking structure when being locked by the locking structure, that is, both ends of the docking member 33 in its extending direction are positioned. In addition, the side of the docking member 33 facing away from the elastomer 32 abuts against the wall surface of the groove 314, so that the docking member 33 is closely attached to the inside of the first base body 31 in the natural state. The docking member 33 maintains this state. When the locking structure contacts the docking member 33, the axes can be on the same axis or close to coaxial.

[0064] Further, as Figure 5 、 Figure 7As shown, the docking member 33 is a nut, and the locking structure includes: a screw 421 passing through the second base body 41. The screw 421 is rotatably connected to the second base body 41 and is used to insert into the docking member 33 and lock with the docking member 33 when inserted to the locking position.

[0065] In addition, as Figure 3 , Figure 5 , Figure 8 shown, the docking member 33 is a polygonal nut, and the groove 314 is a polygonal groove 314 matching the outer shape of the docking member 33; the first card slot 313 is a semi-circular card slot. The position of the docking member 33 in the first base body 31 is defined by the shapes of the card slot and the groove 314. Preferably, the docking member 33 can be a hexagonal copper nut, and the groove 314 is a regular hexagon.

[0066] In addition, as Figure 3 shown, there are multiple screws 421, docking members 33, and elastic bodies 32, and the numbers are the same and are arranged in one-to-one correspondence. The locking structure further includes: a driving member, which drives each screw 421 to insert into the corresponding docking member 33 and lock with the docking member 33. The driving member also drives each screw 421 to disengage from the corresponding docking member 33.

[0067] Specifically, as Figure 3 , Figure 11 shown, the driving member includes: a driving wrench 6 and a transmission assembly 7. The transmission assembly 7 includes: a driving shaft 71, a driving wheel 72 connected to the driving shaft 71, a first driven wheel 73 meshing with the driving wheel 72, and multiple second driven wheels 74 meshing with the first driven wheel 73. The screw 421 is connected to the second driven wheel 74. The number of the second driven wheels 74 is the same as the number of the screws 421 and is arranged in one-to-one correspondence. The driving wrench 6 drives the driving shaft 71 to rotate. The rotation of the driving shaft 71 drives the driving wheel 72 to rotate. The rotation of the driving wheel 72 drives the first driven wheel 73 to rotate. The rotation of the first driven wheel 73 drives multiple second driven wheels 74 to rotate. The rotation of the second driven wheels 74 drives the corresponding screws 421 to rotate, so that each screw 421 is threadedly locked with the corresponding docking member 33. In this embodiment, there are two screws 421, docking members 33, and elastic bodies 32, and there are also two second driven wheels 74. One screw 421 is connected to one second driven wheel 74. Thus, through the arrangement of multiple screws 421, the connection between the first base 3 and the second base 4 is made closer, preventing a gap between the first base 3 and the second base 4 from clamping the inner lining bag.

[0068] Furthermore, at least two of the multiple screws 421 are longitudinally arranged, and at least two of the multiple second driven wheels are longitudinally arranged.

[0069] In addition, as Figure 3 , Figure 11As shown, the driving wrench 6 includes: a wrench base 61, a handle 62, a connecting member 63, and an elastic member 64. The handle 62 is connected to the wrench base 61. The connecting member 63 connects the wrench base 61 and the transmission assembly 7, and the wrench base 61 is connected to the connecting member 63 and moves relative to the second base 4 along the extension direction of the connecting member 63. When the handle 62 rotates, it drives the wrench base 61 to rotate, and the rotation of the wrench base 61 drives the transmission assembly 7. As Figure 10 , Figure 12 shown, when the handle 62 and the wrench base 61 rotate together to a certain position (such as upward), the handle 62 and the wrench base 61 will interfere with the inner lining bag and easily wear the inner lining bag. The wrench base 61 and the handle 62 can be pulled up in a direction away from the second base body 41, so that the wrench base 61 is disengaged from the transmission assembly 7, and then the wrench base 61 is rotated. The wrench base 61 drives the handle to rotate to other directions, but when the wrench base 61 rotates, it will not drive the transmission assembly 7. After the wrench base 61 drives the handle to rotate to the in-place position, release it as Figure 9 , Figure 11 shown, the elastic member 64 will push the wrench base 61 to reset and connect with the transmission assembly 7.

[0070] Furthermore, as Figure 11 , Figure 12 shown, the transmission assembly 7 includes: a drive shaft 71 and a gear set connected to the drive shaft 71. The gear set is connected to the screw 421. The wrench base 61 is slidably connected to the drive shaft 71 along the axis direction of the drive shaft 71 and drives the drive shaft 71 to rotate around its axis. The wrench base 61 can be operably moved along the axis direction of the drive shaft 71 to disengage from the drive shaft 71. The connecting member 63 is an internal hexagonal bolt, and the elastic member 64 is a tower spring. The elastic member 64 is sleeved on the connecting member 63. The wrench base 61 initially has a mounting groove. The bolt column of the connecting member 63 passes through the bottom of the mounting groove and is connected to the drive shaft 71. The elastic member 64 is located in the mounting groove and abuts against the bottom of the mounting groove. When it is necessary to adjust the direction of the wrench base 61 but not drive the screw 421 to rotate, the wrench base 61 is pulled along the axis direction of the drive shaft 71, so that the wrench base 61 is away from the second base body 41 and disengaged from the drive shaft 71. Then, the wrench base 61 is rotated around the connecting member 63 to a suitable position, and the wrench base 61 is released. The elastic member 64 pushes the wrench base 61 to the original position, that is, the position where the wrench base 61 is sleeved on the drive shaft 71. Specifically, in this embodiment, the gear set includes: a driving wheel 72 connected to the drive shaft 71, a first driven wheel 73 meshing with the driving wheel 72, and a plurality of second driven wheels 74 meshing with the first driven wheel 73. In other embodiments, the gear set can be of other structures, or when there is only one screw 421, there can be only one second driven wheel 74.

[0071] As Figure 1 , Figure 13 shown, Figure 13Arrow C in the figure indicates the direction in which the operating handle 62 is tilted and retracted into the wrench base 61. The handle 62 is hinged to the wrench base 61 and can be operably rotated around its hinge with the wrench base 61 to tilt into the wrench base 61 or be pulled out. Specifically, the handle 62 and the wrench base 61 are connected by a bolt 8, so that the handle 62 can be opened or retracted around the bolt 8 connection hole of the wrench base 61 (as Figure 1 shown in). As Figure 13 shown in the open state of the handle 62, when the handle 62 is opened, the handle 62 can be retracted and shaken to drive the drive shaft 71 to rotate by the wrench base 61. The axis of the bolt 8 is perpendicular to the axis of the drive shaft 71.

[0072] Further, as Figure 3 shown, the transmission assembly 7 includes: a drive shaft 71, a driving wheel 72 connected to the drive shaft 71, a first driven wheel 73 meshing with the driving wheel 72, and a plurality of second driven wheels 74 meshing with the first driven wheel 73; the screw 421 is connected to the second driven wheel 74, the number of the second driven wheels 74 is the same as the number of the screws 421, and they are arranged in one-to-one correspondence; the driving wrench 6 drives the drive shaft 71 to rotate, the rotation of the drive shaft 71 drives the driving wheel 72 to rotate, the rotation of the driving wheel 72 drives the first driven wheel 73 to rotate, the rotation of the first driven wheel 73 drives the plurality of second driven wheels 74 to rotate, and the rotation of the second driven wheels 74 drives the corresponding screws 421 to rotate. The transmission assembly 7 further includes a fixed shaft 75, the fixed shaft 75 is connected to the first driven wheel 73 and the second cover plate 411, the transmission assembly 7 is installed on the second base body 41, the second cover plate 411 covers the transmission assembly 7, and the driving wrench 6 is arranged on the side of the second cover plate 411 away from the first base 3.

[0073] In this embodiment, there are multiple screws 421 and docking members 33. In other embodiments, there may be 1 screw 421. At this time, the transmission assembly 7 can be changed accordingly, and only one screw 421 needs to be driven to rotate.

[0074] Another embodiment of the present utility model relates to a fluid discharge system. The fluid discharge system may include a container, a liner bag, and a pusher as involved in the above embodiments. The container is generally an intermediate bulk container. The liner bag is provided with a discharge port and is installed inside the container. Describe the discharge process of the fluid discharge system. First, the liner bag is clamped between a first roller and a second roller. Specifically, first, the locking structure is operated to separate from the docking member, that is, the first roller and the second roller are loosened. Then, the upper part of the liner bag is clamped on the pusher of the container, and then the locking structure is operated to lock and fix with the docking member, and the first roller and the second roller are locked. Next, the driving device is started. Driven by the driving device, the first roller and the second roller of the pusher rotate downward in opposite directions and squeeze the bag body of the liner bag, thereby squeezing the liquid inside the liner bag and causing the liquid to discharge from the discharge port. During the liquid discharge process, as the liquid inside the liner bag decreases, the first roller and the second roller automatically descend with the liquid level under the drive of the driving device and squeeze the liquid.

[0075] The preferred embodiments of the present utility model have been described in detail above. However, it should be understood that if necessary, aspects of the embodiments can be modified to adopt aspects, features, and concepts of various patents, applications, and publications to provide additional embodiments.
