Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] When changing the metering cylinder of an existing quantitative filling machine, the operator needs to stop the machine first, then replace it, and then restart the machine. This process takes a long time and results in a long downtime, which reduces the working efficiency of the quantitative filling machine.

[0024] In view of this, the present invention provides a transmission structure for a quantitative filling machine for food processing. Through the cooperation of a first housing, a first motor, a lead screw, a lead screw nut, a horizontal plate, a concave plate, a through hole, and a lifting part, the quantitative cylinder can be quickly replaced, reducing downtime. This solves the problem that existing quantitative filling machines require operators to stop the machine before replacing the quantitative cylinder, and then restart the machine after replacement, which results in a long replacement time and downtime, thus reducing the working efficiency of the quantitative filling machine.

[0025] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0026] Example 1: By Figure 1-6It is known that the transmission structure of a quantitative filling machine for food processing includes a curved plate 1, a support plate 2 fixedly connected to the upper front of the curved plate 1, a storage tank 3 fixedly connected to the inner wall of the support plate 2, a connecting pipe 4 connected to the bottom of the storage tank 3, and a quantitative cylinder 5 arranged below the connecting pipe 4. The transmission structure of the quantitative filling machine for food processing also includes a moving device 6, a disassembly and assembly device 7, and a stirring device 8. The moving device 6 is located on the front of the curved plate 1; the disassembly and assembly device 7 is located outside the quantitative cylinder 5; and the stirring device 8 is located inside the storage tank 3. The moving device 6 allows for the exchange of two quantitative cylinders 5 of different specifications, the disassembly and assembly device 7 allows for the quick disassembly and assembly of the quantitative cylinder 5, and the stirring device 8 stirs the shrimp paste inside the storage tank 3.

[0027] In the specific implementation process, it is worth noting that the curved plate 1 supports the entire filling machine, the support plate 2 supports the storage tank 3, and the top of the storage tank 3 has a feed inlet. During filling, the worker first pours the shrimp paste into the storage tank 3 through the feed inlet. Then, the worker stirs the shrimp paste inside the storage tank 3 using the stirring device 8. The worker then opens the valve on the outer wall of the connecting pipe 4, and the shrimp paste inside the storage tank 3 enters the metering cylinder 5 through the connecting pipe 4. After completion, the worker closes the valve on the connecting pipe 4 and opens the valve on the discharge pipe at the bottom of the metering cylinder 5. The shrimp paste inside the metering cylinder 5 enters the packaging bottle through the feed pipe, thus performing metered filling of the shrimp paste. The metering cylinder 5 can be quickly disassembled and installed using the disassembly and assembly device 7, and two metering cylinders 5 of different specifications can be exchanged using the moving device 6.

[0028] Specifically, during the filling process, firstly, the staff pours shrimp paste into the storage tank 3 through the inlet. Then, the shrimp paste inside the storage tank 3 is stirred by the stirring device 8. The staff opens the valve on the outer wall of the connecting pipe 4, and the shrimp paste inside the storage tank 3 enters the metering cylinder 5 through the connecting pipe 4. After completion, the staff closes the valve on the connecting pipe 4 and opens the valve on the discharge pipe at the bottom of the metering cylinder 5. The shrimp paste inside the metering cylinder 5 enters the packaging bottle through the inlet pipe, thus performing metered filling of the shrimp paste. The metering cylinder 5 can be quickly disassembled and installed using the disassembly and assembly device 7, and two metering cylinders 5 of different specifications can be exchanged using the moving device 6.

[0029] Example 2: From Figure 1-6It is understood that the moving device 6 includes a first housing 61, a first motor 62, a lead screw 63, a lead screw nut 64, a horizontal plate 65, a concave plate 66, a through hole 67, and a lifting part 68. The first housing 61 is fixed to the front of the curved plate 1 and located below the support plate 2; the first motor 62 is fixed to the side wall of the first housing 61 by bolts; the lead screw 63 is fixed to the output shaft of the first motor 62, and both ends are rotatably connected to the inner wall of the first housing 61 through bearings; the lead screw nut 64 is threaded to the lead screw 63. The outer wall; the horizontal plate 65 is fixed to the front of the lead screw nut 64 and extends to the outside of the first housing 61 through the opening, and is movably connected to the first housing 61; the concave plate 66 is fixed to the front of the horizontal plate 65 and is internally attached to the lower part of the connecting pipe 4; the through hole 67 is provided on the inner wall of the concave plate 66; the lifting part 68 is provided on the surface of the curved plate 1; wherein, under the drive of the first motor 62, the lead screw 63 causes the lead screw nut 64 to drive the horizontal plate 65 to move, thereby causing the concave plate 66 to drive the metering cylinder 5 to move;

[0030] In the specific implementation process, it is worth noting that when replacing the metering cylinder 5, the staff connects the first motor 62 to an external power supply. The model of the first motor 62 is MSMF042L1U2M. The first motor 62 drives the lead screw 63 to rotate, the lead screw 63 drives the lead screw nut 64 to move, the lead screw nut 64 drives the horizontal plate 65 to move, the horizontal plate 65 drives the concave plate 66 to move, the concave plate 66 moves along the connecting pipe 4, and the concave plate 66 drives the two metering cylinders 5 to move the metering cylinder 5 to be used below the connecting pipe 4. After completion, the staff stops the first motor 62, and the shrimp paste inside the connecting pipe 4 enters the interior of the metering cylinder 5 through the through hole 67, realizing the rapid replacement of the metering cylinder 5 and reducing downtime.

[0031] Furthermore, the lifting unit 68 includes a second housing 681, a hydraulic cylinder 682, a crank column 683, and a placement plate 684. The second housing 681 is fixed to the inner wall of the crank plate 1. The hydraulic cylinder 682 is fixed to the top of the inner wall of the second housing 681 by bolts. The crank column 683 is fixed to the output end of the bottom of the hydraulic cylinder 682 by bolts, and its end penetrates through the second housing 681 and is movably connected to the second housing 681. The placement plate 684 is fixed to the end of the crank column 683. The crank column 683 moves the placement plate 684 under the drive of the hydraulic cylinder 682.

[0032] In the specific implementation process, it is worth noting that the staff adjusts the height of the placement plate 684 according to the size of the metering cylinder 5. The staff starts the hydraulic cylinder 682, which is model HSG-80 / 50-200. The hydraulic cylinder 682 drives the crank column 683 to move. The crank column 683 moves in the second box 681 and is limited. The crank column 683 drives the placement plate 684 to move. After the movement is completed, the staff stops the hydraulic cylinder 682 and places the packaging bottle on the placement plate 684, so as to realize the adjustment of the height of the placement plate 684 according to the size of the metering cylinder 5.

[0033] Furthermore, the disassembly and assembly device 7 includes a first clamp 71, a second clamp 72, an insert block 73, an annular sleeve 74, and a sealing ring 75. The annular sleeve 74 is fixed to the bottom of the concave plate 66, and its inner wall is inserted into the upper part of the metering cylinder 5. The first clamp 71 is fitted to the outer wall of the annular sleeve 74. The second clamp 72 is rotatably connected to the outer wall of the first clamp 71 via a pin, and its inner wall is fitted to the outer wall of the annular sleeve 74. The insert block 73 is fixed to the inner walls of the first clamp 71 and the second clamp 72, and its outer wall is inserted into the inside of the annular sleeve 74 and the inner wall of the metering cylinder 5, respectively. The sealing ring 75 is fixed to the inner wall of the annular sleeve 74, and its inner wall is fitted to the upper part of the outer wall of the metering cylinder 5. The first clamp 71 and the second clamp 72 cooperate to release the metering cylinder 5 from its fixation, thereby allowing for disassembly and assembly. The sealing ring 75 improves the sealing between the annular sleeve 74 and the metering cylinder 5.

[0034] In the specific implementation process, it is worth noting that when filling the shrimp paste, the worker moves the metering cylinder 5 and inserts it into the annular sleeve 74. At this time, the sealing ring 75 fits against the outer wall of the metering cylinder 5, improving the sealing between the annular sleeve 74 and the metering cylinder 5. After completion, the worker moves the first clamp 71 and the second clamp 72 and fits them against the outer wall of the annular sleeve 74. At this time, the first clamp 71 and the second clamp 72 drive the insertion block 73 to move, inserting the insertion block 73 into the annular sleeve 74 and the metering cylinder 5 in sequence. Finally, the bolt is turned to fix the first clamp 71 and the second clamp 72 to install the metering cylinder 5. When the worker turns the bolt in the opposite direction to release the fixation between the first clamp 71 and the second clamp 72, the metering cylinder 5 can be disassembled, further improving the effect of replacing the metering cylinder 5.

[0035] Furthermore, the stirring device 8 includes a stirring rod 81, a stirring blade 82, a horizontal column 83, a scraper 84, and a transmission part 85. The stirring rod 81 is rotatably connected to the inner wall of the storage tank 3 via a bearing; the stirring blade 82 is fixed to the outer wall of the stirring rod 81; the horizontal column 83 is fixed to the outer wall of the stirring rod 81; the scraper 84 is fixed to the end of the horizontal column 83, and its outer wall is attached to the inner wall of the storage tank 3; the transmission part 85 is located outside the storage tank 3; wherein, the shrimp paste is stirred by the stirring rod 81 and the stirring blade 82, and the inner wall of the storage tank 3 is cleaned by the horizontal column 83 and the scraper 84.

[0036] In the specific implementation process, it is worth noting that when stirring the shrimp paste inside the storage tank 3, the stirring rod 81 is rotated, which drives the stirring blade 82 to rotate. The stirring blade 82 stirs the shrimp paste inside the storage tank 3. At the same time, the stirring rod 81 drives the horizontal column 83 to rotate, which drives the scraper 84 to rotate. The scraper 84 rotates along the inner wall of the storage tank 3 to scrape off the shrimp paste adhering to the tank wall, ensuring that the inner wall of the storage tank 3 is clean and avoiding material waste.

[0037] Furthermore, the transmission unit 85 includes a housing 851, a second motor 852, pulleys 853, and a belt 854. The housing 851 is fixed to the outer wall of the storage tank 3. The second motor 852 is fixed to the side wall of the storage tank 3 through a motor sleeve. There are two pulleys 853, which are respectively fixed to the output shaft of the second motor 852 and the upper part of the outer wall of the stirring rod 81. The belt 854 is attached to the outer wall of both pulleys 853. Under the drive of the second motor 852, the pulleys 853 cause the belt 854 to rotate, which in turn causes the stirring rod 81 to rotate.

[0038] In the specific implementation process, it is worth noting that the model of the second motor 852 is 1FL6034-1AC61-2AA1. When the staff connects the second motor 852 to an external power supply, the second motor 852 drives the left pulley 853 to rotate, the left pulley 853 drives the belt 854 to rotate, the belt 854 drives the right pulley 853 to rotate, and the right pulley 853 drives the stirring rod 81 to rotate, thereby driving the stirring rod 81 to rotate.

[0039] Specifically, when stirring the shrimp paste inside storage tank 3, firstly, the operator connects the second motor 852 to an external power source. The second motor 852 drives the left pulley 853 to rotate, which in turn drives the belt 854 to rotate. The belt 854 then drives the right pulley 853 to rotate, which in turn drives the stirring rod 81 to rotate. The stirring rod 81 then drives the stirring blade 82 to rotate, which in turn stirs the shrimp paste inside storage tank 3. Next, the stirring rod 81 drives the horizontal column 83 to rotate, which in turn drives... The scraper 84 rotates along the inner wall of the storage tank 3, scraping off the shrimp paste adhering to the tank wall to ensure the inner wall of the storage tank 3 is clean and to avoid material waste. When replacing the metering cylinder 5, firstly, when filling the shrimp paste, the worker moves the metering cylinder 5 and inserts it into the annular sleeve 74. At this time, the sealing ring 75 is in contact with the outer wall of the metering cylinder 5. After that, the worker moves the first clamp 71 and the second clamp 72 to fit the first clamp 71 and the second clamp 72 against the outer wall of the annular sleeve 74. At this point, the first clamp 71 and the second clamp 72 move the insert block 73, inserting it into the annular sleeve 74 and the metering cylinder 5 in sequence. Finally, the bolts are rotated to fix the first clamp 71 and the second clamp 72, thus installing the metering cylinder 5. Then, the first motor 62 drives the lead screw 63 to rotate, which in turn drives the lead screw nut 64 to move. The lead screw nut 64 then drives the horizontal plate 65 to move, which in turn drives the concave plate 66 to move. The concave plate 66 moves along the connecting pipe 4, thus moving the two metering cylinders 5. Move the metering cylinder 5 to the bottom of the connecting tube 4. After that, the staff stops the first motor 62 and quickly replaces the metering cylinder 5. After the replacement is completed, the staff starts the hydraulic cylinder 682. The hydraulic cylinder 682 drives the crank column 683 to move. The crank column 683 moves in the second box 681 and is limited. The crank column 683 drives the placement plate 684 to move. After the movement is completed, the staff stops the hydraulic cylinder 682, places the packaging bottle on the placement plate 684, and performs metered filling of shrimp paste.
