Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a food processing piston filling machine with adjustable volume. Background Art

[0002] Food processing refers to the grain milling, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, as well as the processing of vegetables, fruits and nuts, as well as potatoes, dehydrated vegetables, and canned vegetables, which are directly carried out using agricultural, forestry, animal husbandry and fishery products as raw materials. It is a type of agricultural product processing industry in a broad sense. Food processing requires the use of piston filling machines;

[0003] When the current piston filling machine is in use, the liquid food is added to the interior of the storage tank. After the solenoid valve at the bottom of the storage tank is opened, the liquid food is added to the interior of the material cylinder through the discharge pipe. The solenoid valve is closed to prevent the liquid food from returning to the interior of the storage tank. When the piston filling device is working, it pushes the liquid food outward from the bottom discharge port and squeezes the liquid food into the interior of the packaging can, which can achieve quantitative filling of the liquid food.

[0004] During use, traditional piston filling machines use a piston filling device to push the flowing food outward, and the flowing food is added into the packaging can in a quantitative manner. Since the piston filling device cannot adjust the movement distance of the piston, it cannot control the amount of flowing food added and cannot package the flowing food into packaging cans of different specifications, thereby reducing the applicability of the piston filling machine.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0023] During use, the traditional piston filling machine uses a piston filling device to push the flowing food outward, and the flowing food is added into the packaging can in a quantitative manner. Since the piston filling device cannot adjust the moving distance of the piston, the amount of flowing food added cannot be controlled, and the flowing food cannot be packaged into packaging cans of different specifications, thereby reducing the application range of the piston filling machine;

[0024] In view of this, the utility model provides a food processing piston filling machine with adjustable volume, which has the first beneficial effect.

[0025] Example 1: By Figure 1 、 2 , 3, 4 and 6 show that a food processing piston filling machine with adjustable volume comprises a material cylinder 1, the inner wall of the material cylinder 1 is provided with a piston filling device 2, the piston filling device 2 comprises: a first servo motor 21, detachably connected to the outer wall of the material cylinder 1; two bent rods 22 are provided, both of which are rotatably connected to the inner wall of the material cylinder 1 through bearings, and the bent rod 22 on the side close to the first servo motor 21 is detachably connected to the output end of the first servo motor 21; a cylinder 23, movably connected to the outer walls of the two bent rods 22; a bidirectional screw rod 24, rotatably connected to the inner wall of the cylinder 23 through bearings; Two clamping blocks 25 are provided, both of which are threadedly connected to the outer wall of the bidirectional screw 24 and are movably connected to the outer wall of the cylinder 23. The outer walls of the two clamping blocks 25 are tightly abutted against the outer walls of the two curved rods 22; the connecting rod 26 is rotatably connected to the outer wall of the cylinder 23 through a bearing; the piston 27 is rotatably connected to the outer wall of the connecting rod 26 through a bearing and is movably connected to the inner wall of the cylinder 1; wherein, when the bidirectional screw 24 rotates, the clamping blocks 25 are driven to move inward to fix the cylinder 23 to the outer wall of the curved rod 22, and the first servo motor 21 drives the piston 27 at one end of the connecting rod 26 to move through the curved rod 22;

[0026] In the specific implementation process, it is worth noting that the model of the first servo motor 21 is ECM A-E11320RS. When the bidirectional screw 24 rotates, it drives the clamping block 25 to move inward. The clamping block 25 moves inward to fix the cylinder 23 on the outer wall of the curved rod 22. When the first servo motor 21 is working, it drives the piston 27 at one end of the connecting rod 26 to move through the curved rod 22. The piston 27 pushes the flowing food inside the cylinder 1 outward.

[0027] Furthermore, the inner wall of the material cylinder 1 is connected to a discharge pipe 3, one end of the discharge pipe 3 is connected to a storage tank 4, and the top of the storage tank 4 is connected to a feed port 5;

[0028] In the specific implementation process, it is worth noting that the flowing food inside the storage tank 4 enters the material cylinder 1 from the discharge pipe 3, and the feed port 5 facilitates the flowing food to enter the storage tank 4.

[0031] Specifically, when using the food processing piston filling machine with adjustable volume, the position of the cylinder 23 is adjusted, thereby adjusting the moving range of the piston 27 at one end of the connecting rod 26. The staff twists the bidirectional screw 24 to drive the clamping block 25 to move inward, and the clamping block 25 fixes the cylinder 23 on the outer wall of the bent rod 22. When the first servo motor 21 is working, it drives the connecting rod 26 on the outer wall of the cylinder 23 to move through the bent rod 22. The connecting rod 26 drives the piston 27 to move downward to squeeze the flowing food inside the material cylinder 1 to flow out. The flowing food enters the storage tank 4 from the feed port 5, and the storage tank 4 sends the flowing food into the material cylinder 1 through the discharge pipe 3.

[0033] In the specific implementation process, it is worth noting that the transmission mechanism 92 is composed of two grooved wheels and a belt. The model of the second servo motor 93 is SM80-D601930. When the second servo motor 93 is in operation, it drives the turntable 91 to rotate through the transmission mechanism 92, thereby adjusting the position of the packaging can above the turntable 91.

[0034] Specifically, based on the above-mentioned embodiment 1, when the second servo motor 93 is in operation, it drives the turntable 91 to rotate through the transmission mechanism 92, and the position of the packaging can is adjusted after the turntable 91 rotates.

[0035] Example 3: By Figure 1 、 2 As shown in Figure 5, the tensioning portion 95 includes: a threaded rod 951, which is threadedly connected to the inner wall of the support frame 94 and is rotatably connected to the inner wall of the bottom shell 8 through a bearing; a handwheel 952, which is mounted on one end of the threaded rod 951; wherein, when the handwheel 952 rotates, the support frame 94 is driven to move through the threaded rod 951;

[0036] In the specific implementation process, it is worth noting that when the hand wheel 952 rotates, the support frame 94 is driven to move through the threaded rod 951;

[0037] Specifically, based on the above-mentioned embodiment 1, the staff drives the handwheel 952 to rotate, and the handwheel 952 drives the support frame 94 to move through the threaded rod 951.
