Description

Technical Field

[0001] The invention relates to the technical field of food packaging, and in particular to edible oil filling equipment. Background Art

[0002] Filling equipment is used to fill edible oil into different containers (such as bottles, barrels, cans, etc.), and plays a vital role in the production and packaging of edible oil. Existing edible oil filling equipment can be divided into in-line filling machines and disc filling machines according to the different settings of the filling valves. Among them, the disc filling machine is suitable for filling scenarios with high requirements for filling accuracy and a variety of material types; the in-line filling machine is suitable for large-scale, high-efficiency filling scenarios, and can meet the needs of rapid filling of large amounts of materials.

[0003] For an in-line filling machine, the number of its filling valves is usually between 2 and 10, and the multiple filling valves are arranged linearly, so that multiple containers can be filled simultaneously through a single filling action, thereby greatly improving the filling efficiency of the equipment. However, for a filling machine with this structure, since multiple filling valves are usually fixedly connected to the machine body, and the spacing between multiple filling valves is usually fixed, most of them are only suitable for batch filling of containers of a certain specification. This results in poor adaptability of the equipment when facing containers of different specifications and different filling requirements. For example, when it is necessary to fill a small container, since the spacing between multiple filling valve brackets cannot be adjusted according to the size, specification and shape of the container, problems such as uneven filling, inaccurate docking between the filling valve and the container, or splashing of materials during the filling process may occur.

[0004] This shows that the prior art needs to be further improved and enhanced. Summary of the invention

[0005] In view of the above problems, an embodiment of the present invention provides an edible oil filling device to solve the problem that the existing filling device cannot flexibly adjust the distance between multiple filling valves.

[0011] In some embodiments, the outer wall periphery of the valve body is further provided with an external thread, and any filling valve further comprises: The upper locking member located above the adjusting plate is provided with a first internal thread; The lower locking piece located below the adjusting plate is provided with a second internal thread; The first internal thread and the second internal thread are matched with the external thread respectively, so that the upper locking member and the lower locking member clamp and fix the filling valve to the adjustment plate.

[0012] In some embodiments, the guide member is a guide screw, and a crank is provided at the top of the guide screw, and the filling bracket further includes: The columns fixed to the workbench are located on both sides of the guide screw; A fixing plate for fixing the push piece, with both ends connected to the columns respectively, and a guide nut adapted to the guide screw being arranged in the middle; Driven by the crank handle, the guide nut rotates along with the rotation of the guide screw, so that the fixing plate can move up and down along the extension direction of the guide screw.

[0013] In some embodiments, a connection hole is opened at the edge of the lifting plate, and a strip hole corresponding to the connection hole is opened at the edge of the adjustment plate; The filling bracket also includes a fastener, which can pass through the connecting hole and the strip hole to achieve a detachable connection between the lifting plate and the adjusting plate.

DETAILED DESCRIPTION

[0020] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0021] Reference Figure 1-Figure 6As shown, an embodiment of the present invention provides an edible oil filling device, comprising a body 100, a storage device 200, a filling device 300 and a feeding device 400. The body 100 has a workbench 110 and a working chamber 120 located below the workbench 110; the storage device 200 is located above the workbench 110, the filling device 300 has a filling bracket 310 and a plurality of filling valves 320 arranged on the filling bracket 310, and the feeding device 400 is respectively connected to the storage device 200 and the plurality of filling valves 320.

[0022] Specifically, the filling support 310 includes a guide member 311, a lifting plate 312, a push member 313 and an adjustment plate 314. The guide member 311 is vertically arranged on the surface of the workbench 110, the lifting plate 312 cooperates with the guide member 311, and the push member 313 is located below the lifting plate 312 and contacts the bottom of the lifting plate 312, so that the lifting plate 312 can move up and down along the extension direction of the guide member 311; the adjustment plate 314 is connected to the lifting plate 312, and is spaced apart with a plurality of adjustment slots 3141 respectively adapted to the plurality of filling valves 320, and the plurality of adjustment slots 3141 are arranged in a fan shape, so that the horizontal spacing between the plurality of filling valves 320 can be adjusted as they move in the plurality of adjustment slots 3141.

[0023] It should be noted that, in the present application, the up and down movement of the lifting plate 312 is achieved by the cooperation between the guide member 311 and the lifting plate 312, and in order to improve the smoothness and stability of the movement of the lifting plate 312, the inner diameter of the through hole opened on the lifting plate 312 can be larger than the outer diameter of the guide member 311, so that the cooperation between the two is a clearance cooperation; the pushing member 313 is a structure for driving the movement of the lifting plate 312, which can be a pushing oil cylinder, a pushing air cylinder, etc.; in addition, the connection method between the adjusting plate 314 and the lifting plate 312 can be a fixed connection (such as welding, one-piece molding connection, etc.), or a detachable connection (such as threaded connection, clamping, plug-in, etc.). In the present application, there is no limitation on the cooperation method between the guide member 311 and the lifting plate 312, the specific type of the pushing member 313, the connection method between the adjusting plate 314 and the lifting plate 312, etc.

[0024] It should also be noted that the filling valves 320 in the present application can be configured as 2 to 12, or more, so that the filling device 300 can meet the filling needs in different scenarios; accordingly, the number of the regulating grooves 3141 corresponds to the number of the filling valves 320, and the present application does not limit the specific configuration number of the filling valves 320 and the regulating grooves 3141. Preferably, the spacing between the multiple regulating grooves 3141 is the same, so as to ensure that the multiple filling valves 320 have the same spacing. In addition, the regulating groove 3141 can be a strip groove, or an arc groove, etc., and the present application does not limit the specific structure of the regulating groove 3141.

[0025] In addition, in order to further improve the moving accuracy of the filling valve 320 compared with the adjusting groove 3141, the edge of the adjusting groove 3141 may be provided with scale lines; or, a plurality of depressions (not shown in the figure) may be provided on the inner side wall of the adjusting groove 3141, so that the adjusting groove 3141 forms a plurality of concave positions for limiting the relative position of the filling valve 320. For example, when the user uniformly adjusts the plurality of filling valves 320 to the first concave position of the adjusting groove 3141, the spacings between the plurality of filling valves 320 are all the first spacings; when the user uniformly adjusts the plurality of filling valves 320 to the second concave position of the adjusting groove 3141, the spacings between the plurality of filling valves 320 are all the second spacings, the values ​​of the plurality of first spacings are the same, and the values ​​of the plurality of second spacings are also the same, so that the equal spacing adjustment of the filling valves 320 can be achieved.

[0026] In addition, some filling valves 320 in the prior art are directly fixed on the filling equipment. During the filling process, the filling valve 320 usually extends into the interior of the container. As the filling process proceeds, the material in the container continues to increase. On the one hand, the material will directly contact the filling valve 320, so that when the filling valve 320 is removed from the container, the material attached to the surface of the filling valve 320 is likely to drip to the outside of the container, which not only causes waste of material, but also is not conducive to keeping the equipment clean; on the other hand, when high-speed flowing material enters the container through the filling valve 320, the interaction between the high-speed material and the static material in the container, as well as between the air and the static material, may cause bubbles, foam, etc. to appear in the container. In order to avoid the above situation, preferably, a liquid level detection component can be provided on the filling valve 320, and the filling equipment can also include a control device (not marked in the figure) electrically connected to the liquid level detection component, and the control device is also electrically connected to the pushing member 313; in response to the liquid level signal detected by the liquid level detection component, the control device can control the movement of the pushing member 313 so that the lifting plate 312, the adjusting plate 314 and the filling valve 320 can rise with the increase of the liquid level in the container, thereby avoiding the filling valve 320 from contacting the material in the container as much as possible.

[0027] The edible oil filling equipment provided by the present invention, firstly, through the cooperation between the multiple adjustment slots 3141 arranged in a fan shape opened on the adjustment plate 314 and the multiple filling valves 320, the horizontal spacing between the multiple filling valves 320 can be adjusted by moving in the multiple adjustment slots 3141, so that the filling device 300 can adapt to the filling requirements of containers of different specifications, thereby ensuring the accuracy and uniformity of the filling and improving the versatility of the equipment. Compared with the structure of the filling valve 320 with a fixed spacing in the prior art, the difficulty of adjusting the filling device 300 is greatly simplified, the downtime maintenance time of the equipment is reduced, and it is conducive to improving the filling efficiency of the equipment. Secondly, the guide member 311 is vertically arranged on the surface of the workbench 110, providing precise guidance for the lifting plate 312 to ensure the stability of its up and down movement. The lifting plate 312 cooperates with the guide member 311 and is pushed by the pushing member 313 to achieve precise adjustment of the height of the adjustment plate 314 and the filling valve 320, which not only further expands the application scope of the filling device 300, but also enables the filling valve 320 to gradually rise as the filling process proceeds, thereby greatly reducing the possibility of material in the container splashing to the outside, and effectively avoiding the situation where material drips from the surface of the filling valve 320 and the appearance of foam in the container.

[0028] In some embodiments, continue to refer to Figure 6 As shown, the adjustment plate 314 is further provided with a guide groove 3142 parallel to its length direction, and the guide groove 3142 is connected with the plurality of adjustment grooves 3141, so that when the plurality of filling valves 320 move in the guide groove 3142, the horizontal spacing between the plurality of filling valves 320 can be adjusted at unequal intervals. The guide groove 3142 can be a strip groove or an arc groove, etc.

[0029] In certain specific filling scenarios, such as when eight containers of different specifications arranged in parallel need to be filled at one time, since containers of different specifications usually have different sizes, this requires that the multiple filling valves 320 have different spacings, so that the device can fill different containers more accurately. At this time, by opening a guide groove 3142 on the adjustment plate 314, the multiple filling valves 320 can be moved into the guide groove 3142, and the relative positions of the multiple filling valves 320 in the guide groove 3142 can be flexibly adjusted, so that the multiple filling valves 320 correspond to multiple containers of different specifications. Preferably, the edge of the guide groove 3142 can be provided with scale lines to further improve the accuracy of the unequal spacing adjustment of the multiple filling valves 320.

[0030] In some embodiments, the angles between the guide slot 3142 and the plurality of adjustment slots 3141 decrease sequentially from the two ends of the adjustment plate 314 to the center of the adjustment plate 314 .

[0031] This arrangement can more finely control the moving track of the filling valve 320 on the adjustment plate 314, making the adjustment of the horizontal spacing between the filling valves 320 more accurate. When facing containers with complex shapes and large variations in the spacing between the bottle mouths, the position of the filling valve 320 can be better adjusted according to the characteristics of the container, ensuring that each container can be accurately filled, thereby improving the filling accuracy and efficiency of the equipment.

[0032] It is understandable that the multiple angles between the guide groove 3142 and the multiple adjustment grooves 3141 can also be increased successively from the two ends of the adjustment plate 314 to the center of the adjustment plate 314. This arrangement is similar to the above-mentioned arrangement in which the multiple angles are decreased successively, and both can achieve accurate adjustment of the spacing between the multiple filling valves 320.

[0033] In some embodiments, reference Figure 7 and Figure 8 As shown, any filling valve 320 includes a valve body 321, a valve nozzle 322, a valve core 323 and an annular air bag 324. The valve body 321 has a cavity, a receiving groove 3211 is provided on the periphery of the outer wall of the valve body 321, and a plurality of air inlet holes 3212 connected to the cavity are provided in the receiving groove 3211; the valve nozzle 322 is connected to the bottom of the valve body 321, the valve core 323 is provided in the valve body 321, and the top end of the valve core 323 is connected to the feeding device 400, and the bottom end passes through the cavity and is located inside the valve nozzle 322; the annular air bag 324 is provided in the receiving groove 3211 and is connected to the air inlet holes 3212.

[0034] It should be noted that the cavity in the valve body 321 is connected to the air inlet hole 3212, and can form a gas channel for supplying gas to the annular airbag 324. In order to ensure the sealing performance of the gas channel, an annular partition (not shown in the figure) for isolating the valve core 323 and the inner wall of the cavity can be provided inside the valve body 321. In addition, in order to ensure the uniformity of the air intake process of the annular airbag 324, the multiple air inlet holes 3212 provided in the accommodating groove 3211 are evenly arranged along the circumference of the valve body 321.

[0035] In this arrangement, the sealing and separation of the container opening can be achieved by controlling the inflation and deflation of the annular airbag 324. During filling, the annular airbag 324 is inflated and expanded to fit tightly against the container opening, which can not only prevent the leakage of edible oil and improve the sealing and accuracy of filling, but also play a certain degree of limiting and fixing effect on the container during the filling process, which is conducive to improving the stability of the filling process; after the filling is completed, the annular airbag 324 is deflated and contracted, which facilitates the separation of the filling valve 320 from the container and improves the working efficiency of the equipment.

[0036] Further, refer to Figure 3As shown, the filling equipment also includes an air supply device 500, which has an air pump 510 arranged on the workbench 110 and an air guide branch 520 located above the air pump 510, one end (air inlet end) of the air guide branch 520 is connected to the exhaust port (not shown in the figure) of the air pump 510, and the other end (air outlet end) is connected to the cavity; wherein, driven by the air pump 510, air can flow between the air guide branch 520, the valve body 321 and the annular air bag 324, so that the annular air bag 324 has an expanded state for sealing the container opening and a contracted state separated from the container opening. Moreover, when there are multiple filling valves 320, there are also multiple air outlet ends of the air guide branch 520.

[0037] The air supply device 500 provides a stable air source for the annular airbag 324, further ensuring that the annular airbag 324 can effectively seal the container opening. Whether for high-speed filling or edible oil products with high sealing requirements, the sealing of the container can be guaranteed during the filling process, reducing the leakage of edible oil, and improving product quality and equipment reliability.

[0038] In some embodiments, continue to refer to Figure 7 and Figure 8 As shown, the outer wall periphery of the valve body 321 is also provided with an external thread (not shown in the figure), and any filling valve 320 also includes an upper locking member 325 and a lower locking member 326. Among them, the upper locking member 325 is located above the adjustment plate 314, and the upper locking member 325 is provided with a first internal thread (not shown in the figure); the lower locking member 326 is located below the adjustment plate 314, and is provided with a second internal thread (not shown in the figure); the first internal thread and the second internal thread are respectively matched with the external thread, so that the upper locking member 325 and the lower locking member 326 clamp and fix the filling valve 320 to the adjustment plate 314. Optionally, the upper locking member 325 and the lower locking member 326 can both be locking nuts.

[0039] This arrangement, on the one hand, has a simple and firm structure, so that the installation of the filling valve 320 on the adjustment plate 314 is more stable and not prone to loosening or displacement during the operation of the equipment. Even when the equipment is running for a long time or is subjected to a certain vibration, the position accuracy of the filling valve 320 can be guaranteed, thereby ensuring the accuracy of filling. On the other hand, this structure also allows users to adjust the position of the filling valve 320 more conveniently and quickly, thereby improving the filling efficiency.

[0040] In some embodiments, continue to refer to Figure 4 and Figure 5As shown, the guide member 311 is a guide screw, and a crank 315 is provided at the top of the guide screw. The filling bracket 310 also includes a column 316 and a fixed plate 317. The column 316 is fixed to the workbench 110, and the columns 316 are respectively located on both sides of the guide screw and connected to the lifting plate 312; the fixed plate 317 is used to fix the push member 313, and its two ends are respectively connected to the column 316, and a guide nut (not marked in the figure) adapted to the guide screw is provided in the middle. Specifically, under the drive of the crank 315, the guide nut rotates with the rotation of the guide screw, so that the fixed plate 317 can move up and down along the extension direction of the guide screw.

[0041] The setting of the column 316 can guide the lifting plate 312 to a certain extent during the up and down movement of the lifting plate 312, thereby improving the stability and accuracy of the movement of the lifting plate 312. In addition, the setting of the fixed plate 317 and the crank 315 allows the user to adjust the push member 313 by operating the crank 315, and then adjust the height of the lifting plate 312 and the filling valve 320, so that when filling containers at different heights or adjusting the height of the filling valve 320 according to different filling requirements, the filling process can be accurately controlled, and the adaptability of the equipment and the accuracy of filling can be improved.

[0042] In some embodiments, reference Figure 5 , Figure 6 and Fig. 9 As shown, a connection hole 3121 is provided at the edge of the lifting plate 312, and a strip hole 3143 corresponding to the connection hole 3121 is provided at the edge of the adjusting plate 314; the filling bracket 310 further includes a fastener 318, which can pass through the connection hole 3121 and the strip hole 3143 to achieve a detachable connection between the lifting plate 312 and the adjusting plate 314. The fastener 318 can be a bolt, a screw, a stud, etc.

[0043] This detachable connection method facilitates the assembly, debugging and maintenance of the equipment. For example, when the filling valve 320 needs to be overhauled on a large scale or the adjusting plate 314 needs to be replaced, or when the position of the filling valve 320 needs to be adjusted in a direction perpendicular to the extension direction of the guide screw, the connection between the lifting plate 312 and the adjusting plate 314 can be quickly disassembled, thereby improving the maintenance efficiency of the equipment, reducing the downtime of the equipment, and reducing maintenance costs.

[0044] In some embodiments, reference Fig.10 and Fig.11As shown, the feeding device 400 includes a metering cylinder 410 , a piston 420 , a piston rod 430 , a mounting plate 440 , a moving plate 450 , a driving member 460 , a guide screw 470 and a guide nut 480 . Among them, the metering cylinder 410 is arranged on the workbench 110, the piston 420 is located in the metering cylinder 410, and the top end of the piston rod 430 is connected to the piston 420; the mounting plate 440 is arranged in the working chamber 120, the movable plate 450 is located above the mounting plate 440, and the movable plate 450 is connected to the bottom end of the piston rod 430; the driving member 460 is arranged on the mounting plate 440, and a driving wheel 461 is arranged at its end; the guide screw 470 is located between the workbench 110 and the mounting plate 440, and can pass through the movable plate 450, and a driven wheel 471 matched with the driving wheel 461 is arranged at its end; the guide nut 480 is spirally matched with the guide screw 470, and the guide nut 480 is connected to the movable plate 450.

[0045] Under the drive of the driving member 460, the driven wheel 471 rotates with the rotation of the driving wheel 461, so that the guide nut 480 can move up and down along its extension direction under the rotation of the guide screw 470, and then the piston rod 430 drives the piston 420 during the movement of the moving plate 450. Preferably, the driving member 460 can be a driving motor, a driving motor, etc. In addition, the driving wheel 461 and the driven wheel 471 can be matched in a tooth-tooth manner, a belt-pulley manner, or a sprocket-chain manner. The present application does not limit the specific matching manner of the driving wheel 461 and the driven wheel 471.

[0046] The feeding device 400 provided in the present application improves the accuracy of the metering process by setting up a piston-type metering structure. First, due to the good sealing between the piston 420 and the metering cylinder 410, the leakage of materials can be effectively reduced; second, the piston-type metering structure has an adjustable function, which can flexibly adjust the metering range and accuracy according to actual needs, thereby facilitating the improvement of the qualified rate of a single filling; finally, the piston-type metering structure has good stability and reliability, and can ensure that the feeding device 400 maintains a good working state during a long period of work, reducing the metering error caused by equipment failure.

[0047] It should be noted that, since the filling valve 320 in the present application is configured as multiple, in order to ensure that each filling valve 320 has good filling accuracy, the number of metering cylinders 410 can also be multiple, and the multiple metering cylinders 410 correspond to the multiple filling valves 320 one by one. In addition, in order to achieve synchronous feeding of each filling valve 320, the present application also sets structures such as the mounting plate 440, the moving plate 450, the driving member 460, the guide screw 470 and the guide nut 480, so that the multiple piston rods 430 connected to the multiple pistons 420 can be raised and lowered synchronously, thereby achieving synchronous driving of the multiple pistons 420.

[0048] For ease of understanding, the working process of the feeding device 400 will be briefly described below: During feeding, the material in the storage device 200 enters the metering cylinder 410, and the driving member 460 starts to work and drives the driving wheel 461 on its driving shaft to rotate; at the same time, the driven wheel 471 can rotate synchronously under the drive of the driving wheel 461, and realize the driving of the guide screw 470; with the rotation of the guide screw 470, the guide nut 480 can move up and down along the extension direction of the guide screw 470, that is, the lifting movement of the movable plate 450 is realized; at this time, the piston rod 430 arranged on the movable plate 450 can also move with the movement of the movable plate 450, and finally realizes the driving of the piston 420.

[0049] Further, continue to refer to Fig.10 As shown, the feeding device 400 may further include a guide column 490 connected to the fixed plate 317 and the movable plate 450, and there are multiple guide columns 490, and the multiple guide columns 490 are respectively arranged around the movable plate 450. The arrangement of multiple guide columns 490 is conducive to improving the stability of the piston rod 430 during the movement process.

[0050] In some embodiments, reference Fig.12 and Fig.13 As shown, the filling equipment also includes a conveying device 600, and the conveying device 600 includes a conveyor belt 610 and a bottle blocking assembly 620, the conveyor belt 610 is fixed to the surface of the workbench 110, the bottle blocking assembly 620 is located above the conveyor belt 610, and has an intercepting plate 621 arranged perpendicular to the conveying direction and a bottle blocking plate 622 arranged parallel to the conveying direction, and the intercepting plate 621 and the bottle blocking plate 622 can enclose a filling area corresponding to the positions of multiple filling valves 320.

[0051] This structure can effectively transport the containers to the filling position in an orderly manner and accurately position the containers so that the containers are accurately docked with the filling valve 320. In the continuous filling process, it can ensure that each container can accurately enter the filling area to be filled, thereby improving the filling efficiency and reducing the filling error caused by inaccurate container positioning.

[0052] Further, refer to Fig.13 As shown, the bottle blocking assembly 620 may also include a fixed frame 623 disposed on the conveyor belt 610 and a push-pull member 624 disposed on the fixed frame 623. The interception plate 621 is connected to the push-pull member 624 and can move along the conveying direction perpendicular to the conveyor belt 610 under the push and pull of the push-pull member 624, so as to intercept the container. In addition, along the conveying direction of the conveyor belt 610, the fixed frame 623 is also provided with a slide groove, and the push-pull member 624 has a slider matched with the slide groove. When the slider slides in the slide groove, the relative position of the push-pull member 624 and the interception plate 621 can be adjusted. In addition, the bottle blocking plate 622 is disposed above the fixed frame 623 to guide the container entering the filling area, and the two ends of the bottle blocking plate 622 have arc-shaped guide parts to further improve the guiding effect on the container.
