Description

Technical Field

[0001] This application relates to the field of goods transportation, and particularly to an inner lining bag for container powder. Background Art

[0002] An inner lining bag for a container is used in a container to load fluid bulk granular and powdery products. The inner lining bag for a container uses food-grade materials to keep the goods dry and hygienic during transportation.

[0003] When in use, a plurality of hanging ropes are usually installed on the side wall of the inner lining bag, and the hanging ropes are fixed in the container by tying, so as to realize the installation of the inner lining bag in the container. And before each loading and transportation, it is necessary to check the entire inner lining bag to prevent rupture, that is, it is necessary to remove the inner lining bag installed in the container again. In this process, it is necessary to remove a plurality of hanging ropes in turn. After the inspection, it is also necessary to tie the plurality of hanging ropes in the container again. The whole process is complicated to operate, so it needs to be improved. Summary of the Invention

[0004] In order to improve the problem that the disassembly and assembly of a plurality of hanging ropes are required for inspecting the inner lining bag and the operation is complicated, this application provides an inner lining bag for container powder.

[0005] An inner lining bag for container powder provided by this application adopts the following technical solutions: An inner lining bag for container powder includes a bag body and a support frame arranged in a box body. The support frame includes a connecting rod and a plurality of ring tubes. The ring tubes are coaxially sleeved on the bag body. The plurality of ring tubes are arranged at intervals along the length direction of the bag body. The connecting rod is arranged along the length direction of the bag body. The connecting rod is fixed on the outer side walls of the plurality of ring tubes. A slideway is fixed on the inner wall of the box body. The slideway is arranged along the length direction of the bag body. The connecting rod is inserted into the slideway and can move in the slideway.

[0006] By adopting the above technical solutions, when in use, first pull the support frame out of the box body so that the bag body is exposed outside the box body, which is convenient for inspecting and repairing the bag body. Then, after filling the bag body with granular or powdery goods, push the entire support frame into the box body. During this process, the connecting rod moves in the slideway, and the slideway plays a role in restricting and guiding the connecting rod, so that the support frame can insert the bag body into the box body smoothly. Moreover, the cooperation between the connecting rod and the slideway can restrict the support frame from driving the bag body to shake in the box body, improving the stability of the bag body installed in the box body. When the box body is transported to the designated position and unloaded, pull the support frame out of the box body again. It is convenient for unloading and can inspect the bag body at the same time, and timely repair the damaged parts during transportation. Compared with the prior art of removing the whole bag body from the box body and then tying it in turn after the inspection, it is more convenient.

[0007] Optionally, suction cups are provided on the inner side wall of the annular pipe. The suction cups are communicated with the annular pipe. The suction cups can abut against the bag body. An air suction assembly is provided on the annular pipe. The air suction assembly moves to adsorb the suction cups on the bag body.

[0008] By adopting the above technical solution, after the support frame drives the bag body to be inserted into the box body for storage, the air suction assembly is moved so that the suction cups are adsorbed on the outer side wall of the bag body, realizing the positioning of the bag body on the support frame and preventing the bag body from moving randomly in the support frame. During transportation, the slideway and the connecting rod cooperate to limit the shaking of the entire support frame, and the support frame is connected to the bag body through the suction cups, thereby restricting the movement of the bag body in the box body, reducing the probability of damage to the bag body during transportation, and prolonging the service life of the bag body. Optionally, the air suction assembly includes an air suction pipe and an air suction rod. The air suction pipe is provided on the annular pipe. The air suction rod is inserted into the air suction pipe. A piston is provided in the air suction pipe. The circumferential side wall of the piston fits with the inner wall of the air suction pipe. The piston is fixed to one end of the air suction rod. A pushing spring is sleeved on the air suction rod. The pushing spring is located in the air suction pipe and on the side of the piston away from the bag body. The pushing spring is used to move the piston towards the direction close to the bag body.

[0009] By adopting the above technical solution, in the initial state, under the action of the pushing spring, the air suction rod drives the piston to move towards the direction close to the bag body, so that the bag body closely adheres to the suction cup, sealing the opening of the suction cup. Then, after the support frame is inserted into the box body, the air suction rod is moved away from the bag body, squeezing the pushing spring, so that the piston moves away from the suction cup, thereby extracting the gas in the suction cup, generating suction in the suction cup, and then adsorbing the bag body on the suction cup, that is, the bag body is fixedly connected to the suction cup, realizing the fixed-point fixation of the bag body and preventing the bag body from moving integrally in the support frame.

[0010] Optionally, a chute is formed in the inner wall of the box body along the length direction of the bag body. The air suction rod can be inserted into the chute and move in the chute. The chute penetrates the opening of the box body. A guiding surface is provided on the inner wall of the chute. The guiding surface is located at the end of the box body, and the end of the guiding surface close to the end of the box body is inclined towards the direction close to the center of the box body. The air suction rod can slide on the guiding surface to drive the piston to move away from the bag body.

[0011] By adopting the above technical solution, when the support frame gradually inserts the bag body into the box body, the suction rod is aligned with the corresponding chute and inserted. At the opening of the chute, the suction rod abuts against the guiding surface and moves along the guiding surface, so that the suction rod gradually moves from the end point of the guiding surface into the chute. The guiding surface is inclined, which plays a guiding role in the movement of the suction rod and facilitates the insertion of the suction rod into the chute. At the same time, under the action of the guiding surface, the position of the suction rod also gradually moves away from the bag body, thereby extracting the gas in the suction cup, causing the suction cup to generate negative pressure, and realizing the adsorption of the bag body at the moment when the suction cup enters the box body, so that the bag body is positioned on the support frame after being inserted into the box body, that is, the installation and positioning of the bag body are carried out synchronously, and the operation is convenient.

[0012] Optionally, an exhaust port is communicated with the bag body, the exhaust port is communicated with an exhaust pipe, the exhaust pipe is fixed on the outer side wall of the bag body, a baffle is arranged in the exhaust pipe, and the circumferential side wall of the baffle fits with the inner wall of the exhaust pipe.

[0013] By adopting the above technical solution, during transportation, due to temperature changes, the air pressure in the bag body will change, that is, the gas in the bag body continuously enters and exits the exhaust pipe through the exhaust port, causing the baffle to move along the length direction of the exhaust pipe in the exhaust pipe, thereby realizing the entry and exit of the gas in the bag body when the pressure changes, and further balancing the pressure inside and outside the bag body, preventing the bag body from expanding or contracting due to the pressure difference, and protecting the safety of the goods. The setting of the baffle not only does not affect the flow of gas, but also can prevent the goods in the bag body from leaking out of the bag body, improving the sealing performance of the bag body for storing goods.

[0014] Optionally, one end of the bag body in the length direction is provided with a material port, the annular pipe near the material port is fixed to the bag body, the other end of the bag body is connected with a cylinder, the cylinder is arranged on the box body, the output end of the cylinder is fixed to the bag body, and the cylinder is used to drive one end of the bag body away from the material port to move towards or away from the material port. A contraction assembly for closing the material port is arranged on the annular pipe at the material port.

[0015] By adopting the above technical solution, the loading and unloading of the goods in the bag body are both realized through the feeding and discharging ports. After the goods are loaded into the bag body, the contraction assembly is started to contract the end of the bag body, so that the material port is in a closed state, which is convenient for the transportation of the goods.

[0016] When the goods arrive at the designated point and need to be unloaded, the cylinder is started to drive one end of the bag to move toward the material port. During this process, the bag bends. When the cylinder drives one end of the bag to pass through the material port, it continues to move until the inner wall of the entire bag is completely turned outward, that is, the inside of the bag is completely exposed, so that the goods in the bag can be fully displayed, especially for powdery goods, it is convenient to completely unload the goods in the bag, which not only improves the completeness of unloading, but also improves the cleanliness of the bag, so that different goods can be loaded next time.

[0017] Optionally, the shrinkage component includes two movable plates and two semi-circular discs, the two movable plates are arranged opposite to each other, the movable plates are slidably connected to the ring tube, the two semi-circular discs correspond to the movable plates one by one, the semi-circular discs are arranged on the corresponding movable plates, the two semi-circular discs can be spliced ​​into a disc, the middle part of the disc is provided with a shrinkage opening, and the end of the bag body with a material opening can be penetrated with the shrinkage opening.

[0018] By adopting the above technical solution, in the initial state, the two movable plates are far away from each other, so that when the goods are loaded into the bag body, the two movable plates are driven close to each other, so that the inner wall of the shrinkage opening squeezes the bag body, and the ends of the bag body are gradually gathered until the two semi-circular disks abut against each other. At this time, the ends of the bag body are gathered in the shrinkage opening, that is, the material opening and the bag body are separated by the disc, and the bag body is in a closed state at the position of the disc, so that the goods can be stored in the bag body and are not easy to leak out through the material opening, thereby facilitating the transportation of the goods.

[0019] Optionally, the semi-disc is slidably connected to the movable plate, and the semi-disc can move on the movable plate with the center of the semi-disc as the axis, wherein a motor is provided on one of the movable plates, a rotating gear is coaxially fixed to the motor, a transmission gear is fixed on the outer wall of the semi-disc, and the rotating gear is meshed with the transmission gear.

[0020] By adopting the above technical solution, when the two semi-discs abut against each other to form a disc to tighten the material mouth of the bag body, the motor is started to drive the rotating gear to rotate, which drives the transmission gear to rotate, so that the entire disc rotates to twist the tightened bag body, so that the tightened part of the bag body is screwed together, thereby improving the tightness of the tightened part of the bag body and further improving the sealing of the bag body.

[0021] Optionally, a guide block is provided on the movable plate, a guide groove is provided on the side wall of the semi-circular disk, the guide groove is arranged along the circumference direction of the semi-circular disk, the guide block is embedded in the guide groove and can move in the guide groove.

[0022] By adopting the above technical solution, when the rotating gear drives the transmission gear to drive the disc to rotate, the guide block moves relative to the guide groove, improving the stability of the connection between the semi-disc and the moving plate. The inner wall of the guide groove abuts against the side wall of the guide block, playing a role in restricting and guiding, enabling the disc to rotate on its own and not easily deflect, ensuring that the disc twists the bag body at a fixed point and improving the stability of the disc in tightening the bag body.

[0023] Optionally, a plurality of rollers are rotatably connected to the connecting rod, and the plurality of rollers are arranged at intervals along the length direction of the connecting rod.

[0024] By adopting the above technical solution, when the support frame moves, that is, when the connecting rod moves in the slideway, the rollers move in the slideway, causing the rollers to rotate on their own, thereby changing the sliding friction between the connecting rod and the slideway into the rolling friction between the rollers and the slideway, reducing the frictional force and facilitating the movement of the support frame with the bag body.

[0025] In summary, the present application includes at least one of the following beneficial effects: 1. When the support frame gradually inserts the bag body into the box body, the suction rod is inserted into the corresponding chute. At the opening of the chute, the suction rod abuts against the guiding surface and moves along the guiding surface, so that the suction rod gradually moves from the end point of the guiding surface into the chute. The guiding surface is inclined, playing a guiding role in the movement of the suction rod, facilitating the insertion of the suction rod into the chute. At the same time, the position of the suction rod also gradually moves away from the bag body under the action of the guiding surface, thereby extracting the gas in the suction cup, causing the suction cup to generate negative pressure, and realizing the adsorption of the bag body at the moment when the suction cup enters the box body, so that the bag body is positioned on the support frame after being inserted into the box body, that is, the installation and positioning of the bag body are carried out synchronously; 2. When the goods reach the designated point and need to be unloaded, the air cylinder is started to drive one end of the bag body to move towards the material port. During this process, the bag body is bent. When the air cylinder drives one end of the bag body to pass through the material port and continues to move until the entire inner wall of the bag body is completely turned outwards, that is, the inside of the bag body is completely exposed, so that the goods in the bag body can be fully displayed. Especially for powdery goods, it is convenient to completely unload the goods in the bag body, not only improving the integrity of unloading, but also improving the cleanliness of the bag body for the next loading of different goods.

Specific embodiments

[0028] The following will further elaborate on this application in conjunction with the attached Figure 1-8 drawings.

[0029] The embodiment of this application discloses an inner lining bag for container powder. Referring to Figure 1 and Figure 2 , the inner lining bag for container powder includes a bag body 30 and a support frame 20 arranged in the box body 10. One end of the box body 10 in the length direction is open, and the bag body 30 can be completely inserted into the box body 10 along the length direction of the box body 10. One end of the bag body 30 in the length direction is provided with a material port. After the bag body 30 is inserted into the box body 10, the material port is communicated with the opening of the box body 10, and the loading and unloading of the goods in the bag body 30 are both realized through the inlet - outlet port. The support frame 20 is sleeved on the bag body 30. To facilitate the transportation of the goods in the bag body 30 and realize the closing of the material port, a contraction assembly 80 for closing the material port is provided on the support frame 20.

[0030] Referring to Figure 2 and Figure 3 , the support frame 20 includes a connecting rod 21 and a plurality of ring pipes 22. The ring pipes 22 are coaxially sleeved on the bag body 30, and the plurality of ring pipes 22 are arranged at intervals along the length direction of the bag body 30. One of the ring pipes 22 located at the material port is adhesively fixed to the bag body 30. The connecting rod 21 is arranged along the length direction of the bag body 30, and the connecting rod 21 is fixed on the outer side walls of the plurality of ring pipes 22. A slide way 11 is fixed on the inner wall of the box body 10, and the slide way 11 is arranged along the length direction of the bag body 30. The connecting rod 21 is inserted into the slide way 11 and can move in the slide way 11.

[0031] Reference Figure 2 and Figure 3 Figure 3 [Reference Figure 2 and

[0031] , a plurality of rollers 211 are rotatably connected to the connecting rod 21. The plurality of rollers 211 are arranged at intervals along the length direction of the connecting rod 21, and the rollers 211 are abutted against the inner wall of the slideway 11. When in use, the support frame 20 is first pulled out of the box body 10, that is, the connecting rod 21 slides in the slideway 11. At this time, the rollers 211 roll and slide in the slideway 11, facilitating the movement of the support frame 20 in the box body 10. When the support frame 20 is moved out of the box body 10, the bag body 30 is exposed outside the box body 10, facilitating the inspection and repair of the bag body 30. Then, the shrinkage assembly 80 is opened, and granular or powdery goods are poured into the bag body 30 through the material port. After that, the entire support frame 20 is pushed into the box body 10. During this process, the connecting rod 21 moves in the slideway 11, and the slideway 11 plays a role of restricting and guiding the connecting rod 21, enabling the support frame 20 to insert the bag body 30 flatly into the box body 10. Moreover, the cooperation between the connecting rod 21 and the slideway 11 can restrict the support frame 20 from driving the bag body 30 to shake in the box body 10, improving the stability of the bag body 30 installed in the box body 10. When the box body 10 is transported to the designated position and unloaded, the support frame 20 is pulled out of the box body 10 again. While facilitating unloading, the bag body 30 can be inspected, and the damaged parts during transportation can be repaired in time. Compared with the prior art of disassembling the whole bag body 30 from the box body 10 and then performing the operation of tying it up in sequence after inspection, it is more convenient.]]

[0032] Reference Figure 3 and Figure 4 Figure 4 [Reference Figure 3 and

[0032] , in order to increase the stability of the installation of the bag body 30 on the support frame 20, an air suction assembly 40 is provided on the annular pipe 22. The air suction assembly 40 is connected to the suction cup 50. The opening of the suction cup 50 faces the bag body 30 and is attached to the outer side wall of the bag body 30. Specifically, the air suction assembly 40 includes an air suction pipe 41 and an air suction rod 42. The air suction pipe 41 is fixed on the annular pipe 22. The air suction pipe 41 is arranged along the radial direction of the annular pipe 22. The annular pipe 22 is internally provided with a cavity. The air suction pipe 41 and the suction cup 50 are both communicated with the cavity.]]

[0033] Reference Figure 4 Figure 4 [Reference

[0033] , the air suction rod 42 is inserted into the air suction pipe 41. A piston 43 is arranged in the air suction pipe 41. The circumferential side wall of the piston 43 is attached to the inner wall of the air suction pipe 41. The piston 43 is fixed to one end of the air suction rod 42. A pushing spring 44 is sleeved on the air suction rod 42. The pushing spring 44 is located in the air suction pipe 41 and on the side of the piston 43 away from the bag body 30. The pushing spring 44 is used to move the piston 43 towards the direction close to the bag body 30.]]

[0034] In the initial state, under the action of the pushing spring 44, the suction rod 42 drives the piston 43 to move towards the direction close to the bag body 30, so that the bag body 30 is only attached to the suction cup 50, sealing the opening of the suction cup 50. Then, after inserting the support frame 20 into the box body 10, the suction rod 42 is moved away from the bag body 30, squeezing the pushing spring 44, so that the piston 43 moves away from the suction cup 50, thereby extracting the gas in the suction cup 50, generating suction force in the suction cup 50, and then adsorbing the bag body 30 on the suction cup 50, that is, the bag body 30 is fixedly connected to the suction cup 50, realizing the fixed-point fixation of the bag body 30, so that the bag body 30 cannot move integrally in the support frame 20.

[0035] Referring to Figure 4 and Figure 5 , in order to facilitate driving the movement of the suction rod 42, a chute 12 is provided on the inner wall of the box body 10 along the length direction of the bag body 30. The suction rod 42 can be inserted into the chute 12 and move in the chute 12. The chute 12 penetrates the opening of the box body 10. A guiding surface 13 is cut on the inner wall of the chute 12. The guiding surface 13 is located at the opening of the box body 10, and one end of the guiding surface 13 close to the opening of the box body 10 is inclined towards the direction close to the center of the box body 10. The suction rod 42 can slide on the guiding surface 13 to drive the piston 43 to move away from the bag body 30.

[0036] When the support frame 20 gradually inserts the bag body 30 into the box body 10, the suction rod 42 is inserted into the corresponding chute 12. At the opening of the chute 12, the suction rod 42 abuts against the guiding surface 13 and moves along the guiding surface 13, so that the suction rod 42 gradually moves from the end point of the guiding surface 13 into the chute 12. The guiding surface 13 is inclined, which plays a guiding role in the movement of the suction rod 42, facilitating the insertion of the suction rod 42 into the chute 12. At the same time, the position of the suction rod 42 also gradually moves away from the bag body 30 under the action of the guiding surface 13, thereby extracting the gas in the suction cup 50, generating negative pressure in the suction cup 50, and realizing the adsorption of the bag body 30 at the moment when the suction cup 50 enters the box body 10, so that the bag body 30 is positioned on the support frame 20 after being inserted into the box body 10, that is, the installation and positioning of the bag body 30 are carried out synchronously, and the operation is convenient.

[0037] Referring to Figure 3 and Figure 6 , during transportation, due to temperature changes, the air pressure in the bag body 30 will change. To prevent the bag body 30 from expanding or contracting due to the pressure difference, an exhaust port 31 is penetrated and opened on the top wall of the bag body 30. The exhaust port 31 is communicated with an exhaust pipe 60. The exhaust pipe 60 is fixed on the outer side wall of the bag body 30. A baffle 61 is provided in the exhaust pipe 60. The circumferential side wall of the baffle 61 fits with the inner wall of the exhaust pipe 60.

[0038] When the air pressure inside the bag body 30 changes, the gas in the bag body 30 continuously enters and exits the exhaust pipe 60 through the exhaust port 31, causing the baffle 61 to move along the length direction of the exhaust pipe 60 in the exhaust pipe 60. Thus, the gas inside the bag body 30 can enter and exit when the pressure changes, further balancing the pressure inside and outside the bag body 30, preventing the bag body 30 from expanding or contracting due to the pressure difference, and protecting the safety of the goods. The setting of the baffle 61 neither affects the flow of the gas nor prevents the goods in the bag body 30 from leaking out of the bag body 30, improving the sealing performance of the bag body 30 for storing goods.

[0039] Referring to Figure 3 and Figure 7 , in order to improve the integrity of unloading, a cylinder 70 is connected to the end of the bag body 30 far from the material inlet. The cylinder 70 is installed on the box body 10 by bolts. The output end of the cylinder 70 is fixed to the bag body 30. The cylinder 70 is used to drive the end of the bag body 30 far from the material inlet to move towards or away from the material inlet.

[0040] When the goods reach the designated point and need to be unloaded, the cylinder 70 is started to drive one end of the bag body 30 towards the material inlet. During this process, the bag body 30 is bent. When the cylinder 70 drives one end of the bag body 30 to pass through the material inlet and continues to move until the inner wall of the entire bag body 30 is completely turned outwards, that is, the inside of the bag body 30 is completely exposed, so that the goods inside the bag body 30 can be fully displayed. Especially for powdery goods, it is convenient to completely unload the goods in the bag body 30, not only improving the integrity of unloading but also improving the cleanliness of the bag body 30 for the next loading of different goods.

[0041] Referring to Figure 3 and Figure 8 , the contraction assembly 80 includes two moving plates 81 and two semi - discs 82. The two moving plates 81 are arranged oppositely. The moving plates 81 are slidably connected to the annular pipe 22. Specifically, the moving plates 81 can move along the radial direction of the annular pipe 22 on the annular pipe 22. The two semi - discs 82 correspond to the moving plates 81 one by one. The semi - discs 82 are arranged on the corresponding moving plates 81. Specifically, the moving plates 81 are provided with guide blocks 811, and the side walls of the semi - discs 82 are provided with guide grooves 822. The guide grooves 822 are arranged along the circumferential direction of the semi - discs 82. The guide blocks 811 are embedded in the guide grooves 822 and can move in the guide grooves 822. The two semi - discs 82 can be spliced into a disc. A contraction opening 821 is opened in the middle of the disc. The inner wall of the contraction opening 821 is serrated. The end of the bag body 30 provided with the material inlet can pass through the contraction opening 821.

[0042] In the initial state, the two moving plates 81 are away from each other. After the goods are loaded into the bag body 30, the two moving plates 81 are driven to approach each other, so that the inner walls of the contraction openings 821 squeeze the bag body 30, causing the ends of the bag body 30 to gradually close up until the two semi - discs 82 abut against each other. At this time, the ends of the bag body 30 are constricted in the contraction openings 821, that is, the material inlet is separated from the bag body 30 by the disc, and the position of the bag body 30 at the disc is in a closed state, enabling the goods to be stored in the bag body 30 and not easily leaking out through the material inlet, thus facilitating the transportation of the goods.

[0043] When the two semi - discs 82 abut against each other to form a disc to constrict the material inlet of the bag body 30, the disc is rotated, causing the guide blocks 811 to move relative to the guide grooves 822, so that the entire disc rotates self - rotatably to twist the constricted bag body 30, making the constricted part of the bag body 30 twist together, improving the tightness of the constricted part of the bag body 30, and further enhancing the sealing performance of the bag body 30.

[0044] When the two semi - discs 82 are spliced together, the two moving plates 81 are in a state of approaching each other. When the support frame 20 inserts the bag body 30 into the box body 10, the ends of the moving plates 81 just abut against the inner side wall of the box body 10, thereby restricting the two moving plates 81 from moving away from each other, that is, maintaining the state where the two semi - discs 82 abut against each other, ensuring the tightening effect of the contraction openings 821 on the bag body 30 and preventing the opening of the material inlet.

[0045] Refer to Figure 8 , in which, in order to facilitate driving the disc to rotate, a motor 90 is provided on one of the moving plates 81. The motor 90 is coaxially fixed with a rotating gear 91, and a transmission gear 823 is fixed on the outer side wall of the semi - disc 82. The rotating gear 91 meshes with the transmission gear 823. Starting the motor 90 to drive the rotating gear 91 to rotate and drive the transmission gear 823 to rotate can drive the disc to rotate self - rotatably, and the operation is convenient.

[0046] The implementation principle of an inner lining bag for container powder in an embodiment of the present application is as follows: During use, first pull out the support frame 20 from the box body 10, so that the bag body 30 is exposed outside the box body 10, facilitating inspection and repair of the bag body 30. Then, after filling the bag body 30 with granular or powdered goods, push the entire support frame 20 into the box body 10. During this process, the connecting rod 21 moves in the slideway 11, and the slideway 11 plays a role in restricting and guiding the connecting rod 21, enabling the support frame 20 to insert the bag body 30 flatly into the box body 10. Moreover, the cooperation between the connecting rod 21 and the slideway 11 can restrict the support frame 20 from driving the bag body 30 to shake in the box body 10, improving the stability of the bag body 30 installed in the box body 10. When the box body 10 is transported to the designated location and unloaded, pull out the support frame 20 from the box body 10 again. This not only facilitates unloading but also enables inspection of the bag body 30, and timely repair of the damaged parts during transportation.
