Description

Technical Field

[0001] This application relates to the technical field of container liquid bags, and particularly relates to a container liquid bag. Background Art

[0002] A container liquid bag is a packaging for containing liquids that is usually installed inside a container.

[0003] Existing container liquid bags generally have connecting parts such as hooks provided at the top of the bag body, and a material passing port for inlet and outlet of materials is opened at one end of the bag body. Users can first connect the top of the container liquid bag to the inner wall of the container through these connecting parts, then load the liquid to be transported into the container liquid bag from the material passing port, and then close the material passing port and the container. After the container is transported to the unloading location, the user needs to first open the side door of the container near the material passing port, and then connect a pipeline to the material passing port so that the liquid in the container liquid bag naturally flows out along the pipeline.

[0004] However, since components such as valves and protective covers need to be provided on the material passing port, the bottom end of the material passing port needs to be more than ten centimeters higher than the inner bottom wall of the container. Consequently, when the container is placed flat, the liquid in the container liquid bag cannot all flow out naturally from the material passing port. Workers need to use a forklift or a crane to lift the end of the container far from the material passing port upward in order to make as much liquid in the container liquid bag flow out from the material passing port as possible, which makes the unloading process of the container liquid bag time-consuming and laborious.

[0005] In view of this, there is a need to provide a container liquid bag. Summary of the Invention

[0006] In order to solve the problem that the unloading process of the existing container liquid bag is time-consuming and laborious, this application provides a container liquid bag.

[0007] A container liquid bag provided by this application adopts the following technical solution: It includes a bag body, a fixing member, a winding member, and a driving component. A material passing port is opened on one side of the bag body. The fixing member is provided at the top of the bag body and can be connected to the inner top wall of the container. One end of the winding member is connected to the end of the bag body far from the material passing port, and the other end of the winding member extends under the outer bottom wall of the bag body after bypassing the junction of the end of the bag body far from the material passing port and the bottom of the bag body. The driving component is in transmission connection with the winding member, and the driving component can drive the bottom end of the winding member away from the material passing port, or close to the material passing port and drive the junction of the end of the bag body far from the material passing port and the bottom of the bag body to approach the material passing port.

[0008] By adopting the above technical solution, before loading the liquid to be transported into the container flexible tank, the user can control the driving assembly to drive the bottom end of the winding member away from the material passing port, so that the winding member will not interfere with the loading of the liquid to be transported into the container flexible tank; then after transporting the container flexible tank and the outer container to the unloading location, the user can first open the side door of the container near the material passing port, and then connect the pipeline to the material passing port, so that the liquid in the container flexible tank naturally flows out of the bag along the pipeline; when the liquid level in the container flexible tank reaches the bottom end of the material passing port, the user can control the driving assembly to drive the bottom end of the winding member close to the material passing port. At this time, because the top of the bag body is fixed on the inner bottom wall of the container, the junction of the end of the bag body far from the material passing port and the top of the bag body cannot move towards the direction close to the material passing port. Therefore, both ends of the winding member will be straightened and drive the junction of the end of the bag body far from the material passing port and the bottom of the bag body towards the direction close to the material passing port, thereby reducing the inner bottom wall area of the container flexible tank and raising the liquid level, and the remaining liquid in the container flexible tank can automatically flow out from the material passing port, so that workers do not need to use a forklift or a crane to cooperate with the unloading process of the container flexible tank, thus making the unloading process of the container flexible tank time-saving and labor-saving.

[0009] Specifically, the winding member is a wide belt, and the top end of the wide belt is connected to the junction of the end of the bag body far from the material passing port and the top of the bag body.

[0010] By adopting the above technical solution, the setting of the wide belt can reduce the pressure between the winding member and the bag body, so that the bag body is not easily cut or torn due to excessive pressure between the winding member and the bag body.

[0011] Further, the driving assembly includes a telescopic cylinder and a connecting plate. The cylinder body of the telescopic cylinder is arranged on the outer bottom wall of the bag body, and the piston rod of the telescopic cylinder is connected to the connecting plate and drives the connecting plate to approach or move away from the material passing port; The connecting plate is connected to the bottom end of the winding member.

[0012] By adopting the above technical solution, the user can drive the connecting plate to approach or move away from the material passing port by driving the piston rod of the telescopic rod to extend and retract.

[0013] Further, one side edge of the connecting plate is connected to the piston rod of the telescopic cylinder, the other side edge of the connecting plate is connected to the bottom end of the winding member, balls for abutting against the bag body are arranged on the top surface of the connecting plate, and balls for abutting against the inner wall of the container are arranged on the bottom surface of the connecting plate.

[0014] By adopting the above technical solution, the setting of the ball bearings can reduce the frictional force between the connecting plate and the bag body and between the connecting plate and the inner wall of the container. This not only prevents the connecting plate from easily damaging the bag body due to excessive frictional force with the bag body during movement, but also facilitates the movement of the connecting plate under the heavy pressure of the liquid in the containerized liquid bag.

[0015] Furthermore, the drive assembly further includes a control pipe. The bag body is provided with a fixing strap. Both ends of the fixing strap are connected to the outer bottom wall of the bag body. A fixing channel is formed between the body of the fixing strap and the outer bottom wall of the bag body. The inside of the telescopic cylinder is divided into a rod chamber and a rodless chamber by its own piston rod. A control hole leading to the outside is opened on the inner wall of the rodless chamber. One end of the control pipe is connected to the control hole, and the other end of the control pipe passes through the fixing channel and extends to the side door of the container near the material inlet.

[0016] By adopting the above technical solution, during loading or unloading, the user can drive the piston rod in the telescopic cylinder by connecting the suction device to the control pipe; before transporting the containerized liquid bag, the user can first remove the control pipe from the suction device and then set the control pipe through the fixing channel, so as to be able to limit the position of the control pipe through the fixing strap, which is convenient for the user to directly pick up the control pipe from the side door of the container near the unloading port during unloading.

[0017] Specifically, the fixing member is a hook.

[0018] By adopting the above technical solution, the hook can fix the containerized liquid bag on the inner top wall of the container by connecting with the hanging holes or rings provided on the inner wall of the container.

[0019] Specifically, a material passing valve is provided at the material inlet. The material passing valve includes a valve body, a valve core and a wrench. A material passing channel is formed in the valve body. One end of the material passing channel is connected to the material inlet. The valve core is arranged in the material passing channel. One end of the wrench is provided with a rotating shaft, and this rotating shaft is in transmission connection with the valve core and can drive the valve core to rotate to change the on-off of the material flow in the material passing channel.

[0020] By adopting the above technical solution, the user can change the on-off of the material flow in the material passing channel by rotating the wrench.

[0021] Specifically, a ventilation port is opened at the top of the bag body. A one-way valve is provided at the ventilation port, and the one-way valve can prevent external gas from passing through the ventilation port and entering the interior of the bag body.

[0022] By adopting the above technical solution, the one-way valve can prevent external gas from passing through the vent and entering the interior of the bag, so that when the container liquid bag is loaded, the air inside the bag can pass through the vent and leave the interior of the bag; while during the transportation of the container liquid bag, external gas cannot pass through the vent and enter the interior of the bag, thereby protecting the liquid inside the bag.

[0023] Specifically, it further includes a connecting member. A quick feeding port leading to the interior of the bag is provided on one side of the bag body close to the material feeding port. A stitching part is provided on one side edge of the quick feeding port, and the remaining side edges of the quick feeding port can be connected to the stitching part via the connecting member to block the quick feeding port.

[0024] By adopting the above technical solution, when loading viscous liquid into the container liquid bag, the user can quickly load the material by opening the quick feeding port.

[0025] Furthermore, the connecting member is a zipper.

[0026] By adopting the above technical solution, the user can quickly open or close the quick feeding port by pulling the zipper.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. It includes a bag body, a fixing member, a winding member and a driving assembly. A material passing opening is provided on one side of the bag body. The fixing member is arranged at the top of the bag body and can be connected to the inner top wall of the container. One end of the winding member is connected to the end of the bag body far from the material passing opening, and the other end of the winding member bypasses the junction of the end of the bag body far from the material passing opening and the bottom of the bag body and extends below the outer bottom wall of the bag body. The driving assembly is in transmission connection with the winding member, and the driving assembly can drive the bottom end of the winding member away from the material passing opening, or close to the material passing opening and drive the junction of the end of the bag body far from the material passing opening and the bottom of the bag body close to the material passing opening. Before loading the liquid to be transported into the container liquid bag, the user can control the driving assembly to drive the bottom end of the winding member away from the material passing opening so that the winding member will not interfere with the loading of the liquid to be transported into the container liquid bag. Then, after transporting the container liquid bag and the outer container to the unloading location, the user can first open the side door of the container near the material passing opening, and then connect the pipeline to the material passing opening so that the liquid in the container liquid bag naturally flows out of the bag along the pipeline. When the liquid level in the container liquid bag reaches the bottom end of the material passing opening, the user can control the driving assembly to drive the bottom end of the winding member close to the material passing opening. At this time, because the top of the bag body is fixed on the inner bottom wall of the container and the junction of the end of the bag body far from the material passing opening and the top of the bag body cannot move towards the direction close to the material passing opening, the two ends of the winding member will be straightened and drive the junction of the end of the bag body far from the material passing opening and the bottom of the bag body towards the direction close to the material passing opening, thereby reducing the area of the inner bottom wall of the container liquid bag and raising the liquid level, and the remaining liquid in the container liquid bag can automatically flow out from the material passing opening, so that workers do not need to use a forklift or a crane to cooperate with the unloading process of the container liquid bag, thus making the unloading process of the container liquid bag time-saving and labor-saving. 2. It further includes a connecting member. A quick feeding opening leading to the inside of the bag is provided on the side of the bag body near the material passing opening. A sewing part is provided on one side edge of the quick feeding opening, and the remaining side edges of the quick feeding opening can be connected to the sewing part via the connecting member to block the quick feeding opening, so that when loading viscous liquid into the container liquid bag, the user can quickly load the material by opening the quick feeding opening.

Detailed implementation manners

[0031] The following is further described in conjunction with the attached Figures 1-5 drawings: Referring to Figure 1 , Figure 2 and Figure 4 , a container liquid bag is installed inside the container 6. The container liquid bag specifically includes a bag body 1, a fixing member 2, a winding member 3, a driving assembly 4 and a connecting member 5. A material passing port is formed on one side of the bag body 1, and a material passing valve 13 is provided at the material passing port. The material passing valve 13 includes a valve body 131, a valve core and a wrench 132. A material passing channel is formed inside the valve body 131. One end of the material passing channel is connected to the material passing port. The valve core is arranged inside the material passing channel. One end of the wrench 132 is provided with a rotating shaft, and the rotating shaft is in transmission connection with the valve core and can drive the valve core to rotate so as to change the on-off of the material flow in the material passing channel, so that the user can change the on-off of the material flow in the material passing channel by rotating the wrench 132; an air vent is formed at the top of the bag body 1, and a check valve 15 is provided at the air vent. The check valve 15 can prevent external gas from passing through the air vent and entering the inside of the bag body 1, so that when the container liquid bag is loaded, the air inside the bag body 1 can pass through the air vent and leave the inside of the bag body 1; when the container liquid bag is transported, external gas cannot pass through the air vent and enter the inside of the bag body 1, thereby protecting the liquid inside the bag body 1.

[0032] Referring to Figure 1 , Figure 2 and Figure 4, nine fixing members 2 are arranged in a 3x3 array at the top of the bag body 1. The fixing member 2 can be a hook, so that the container liquid bag can be fixed on the inner top wall of the container 6 by connecting the hook with the hanging hole or hanging ring arranged on the inner wall of the container 6; a quick feeding port leading to the inside of the bag is opened on one side of the bag body 1 close to the material feeding port. A sewing part 14 is arranged on one side edge of the quick feeding port. The other side edges of the quick feeding port can be connected to the sewing part 14 via a connecting member 5 to block the quick feeding port. The connecting member 5 can be a zipper, so that when loading viscous and non-leakable liquids such as asphalt, the user can quickly open or close the quick feeding port by pulling the zipper; when loading viscous and leakable liquids such as mud, the connecting member 5 can also be a sewing thread, so that the liquid is not easy to leak from the joint of the sewing part 14 and the connecting member 5.

[0033] See Figure 3 and Figure 4 , three winding members 3 are arranged on the bag body 1. The winding member 3 can be a wide-edge belt, so as to be able to reduce the pressure between the winding member 3 and the bag body 1, so that the bag body 1 is not easy to be cut or torn due to excessive pressure between the winding member 3 and the bag body 1; the top ends of each wide-edge belt are connected to the junction of the end of the bag body 1 far from the material feeding port and the top of the bag body 1; three rows of limiting belts 11 are arranged at the end of the bag body 1 far from the material feeding port. Each row of limiting belts 11 corresponds to one winding member 3. Each row of limiting belts 11 includes three limiting belts 11. Both ends of each limiting belt 11 are connected to the bag body 1. A limiting channel is formed between the belt body of each limiting belt 11 and the bag body 1. The bottom end of each winding member 3 first passes through all the limiting channels on each row of limiting belts 11, and then bypasses the junction of the end of the bag body 1 far from the material feeding port and the bottom of the bag body 1 and extends to the lower part of the outer bottom wall of the bag body 1.

[0034] See Figure 2 , Figure 3 and Figure 5 , the driving assembly 4 includes a telescopic cylinder 41, a connecting plate 42 and a control pipe 43. The cylinder body of the telescopic cylinder 41 is arranged on the outer bottom wall of the bag body 1. The piston rod of the telescopic cylinder 41 is connected to the connecting plate 42 and drives the connecting plate 42 to approach or move away from the material feeding port. The bottom ends of each winding member 3 are all connected to the connecting plate 42; ball bearings 421 for abutting against the bag body 1 are arranged on the top surface of the connecting plate 42, and ball bearings 421 for abutting against the inner wall of the container 6 are arranged on the bottom surface of the connecting plate 42, so as to be able to reduce the friction between the connecting plate 42 and the bag body 1 and between the connecting plate 42 and the inner wall of the container 6 through the arrangement of the ball bearings 421. It not only makes the connecting plate 42 not easy to wear the bag body 1 due to excessive friction with the bag body 1 during movement, but also facilitates the movement of the connecting plate 42 under the heavy pressure of the liquid in the container liquid bag.

[0035] See Figure 2 andFigure 3 On the bag body 1, there is a fixing belt 12. Both ends of the fixing belt 12 are connected to the outer bottom wall of the bag body 1. A fixing channel is formed between the belt body of the fixing belt 12 and the outer bottom wall of the bag body 1. The inside of the telescopic cylinder 41 is divided into a rod chamber and a rodless chamber by its own piston rod. A control hole leading to the outside is opened on the inner wall of the rodless chamber. One end of the control pipe 43 is connected to the control hole, and the other end of the control pipe 43 passes through the fixing channel and extends to the side door of the container 6 near the material feeding port, so that when loading or unloading materials, the user can drive the piston rod in the telescopic cylinder 41 to move by connecting the suction device to the control pipe 43; before transporting the container liquid bag, the user can first remove the control pipe 43 from the suction device, and then set the control pipe 43 through the fixing channel, so as to be able to limit the position of the control pipe 43 through the fixing belt 12, which is convenient for the user to directly pick up the control pipe 43 from the side door of the container 6 near the unloading port when unloading materials.

[0036] The using process of the container liquid bag described in this application is as follows: Before loading the liquid to be transported into the container liquid bag, the user can first fix the top of the container liquid bag on the inner top wall of the container 6 through a hook, and then connect the suction device to the control pipe 43 to drive the piston rod in the telescopic cylinder 41 to extend out of the cylinder body, so as to be able to drive the bottom end of the winding member 3 away from the material feeding port, so that the winding member 3 will not interfere with the loading of the liquid to be transported in the container liquid bag; Then, after transporting the container liquid bag and the container 6 with the outer cover to the unloading location together, the user can first open the side door of the container 6 near the material feeding port, and then connect the pipeline to the material feeding port, so that the liquid in the container liquid bag naturally flows out of the bag along the pipeline; When the liquid level in the container liquid bag reaches the bottom end of the material feeding port, the user can first connect the suction device to the control pipe 43 to drive the piston rod in the telescopic cylinder 41 to retract into the cylinder body, so as to be able to drive the bottom end of the winding member 3 close to the material feeding port. At this time, because the top of the bag body 1 is fixed on the inner bottom wall of the container 6, the junction of the end of the bag body 1 far from the material feeding port and the top of the bag body 1 cannot move towards the direction close to the material feeding port, so both ends of the winding member 3 will be straightened and drive the junction of the end of the bag body 1 far from the material feeding port and the bottom of the bag body 1 towards the direction close to the material feeding port, thereby reducing the area of the inner bottom wall of the container liquid bag and raising the liquid level, and the remaining liquid in the container liquid bag can automatically flow out from the material feeding port; after there is no liquid in the material feeding port, then enter the container 6 to remove, fold and recycle the container liquid bag.

[0037] The implementation principle of the container liquid bag described in this application is as follows: Before loading the liquid to be transported into the container flexible tank, the user can first fix the top of the container flexible tank on the inner top wall of the container 6 through a lifting hook, and then connect the suction device to the control pipe 43 to drive the piston rod in the telescopic cylinder 41 to extend out of the cylinder body, so as to be able to drive the bottom end of the winding member 3 away from the material passing port, so that the winding member 3 will not interfere with the loading of the liquid to be transported in the container flexible tank; Then, after transporting the container flexible tank and the outer container 6 to the unloading location together, the user can first open the side door of the container 6 close to the material passing port, and then connect the pipeline to the material passing port, so that the liquid in the container flexible tank naturally flows out of the bag along the pipeline; When the liquid level in the container flexible tank reaches the bottom end of the material passing port, the user can first connect the suction device to the control pipe 43 to drive the piston rod in the telescopic cylinder 41 to retract into the cylinder body, so as to be able to drive the bottom end of the winding member 3 close to the material passing port. At this time, because the top of the bag body 1 is fixed on the inner bottom wall of the container 6, the junction of the end of the bag body 1 far from the material passing port and the top of the bag body 1 cannot move towards the direction close to the material passing port. Therefore, both ends of the winding member 3 will be straightened and drive the junction of the end of the bag body 1 far from the material passing port and the bottom of the bag body 1 towards the direction close to the material passing port, thereby reducing the area of the inner bottom wall of the container flexible tank and raising the liquid level. The remaining liquid in the container flexible tank 6 of the container can automatically flow out from the material passing port; after there is no liquid in the material passing port, enter the interior of the container 6 to remove, fold and recycle the container flexible tank, so that workers do not need to use a forklift or a crane to cooperate with the unloading process of the container flexible tank, thus making the unloading process of the container flexible tank time-saving and labor-saving.
