Description

Technical Field

[0001] This utility model relates to the field of protein powder processing technology, specifically to a can sealing machine for protein powder cans. Background Technology

[0002] Protein powder can sealing machines are automated equipment specifically designed for the sealing process of protein powder canned products. They are mainly used to seal the can containing protein powder with the can lid, ensuring the product's airtightness, safety, and shelf life during storage, transportation, and sales. Their core function is to apply specific pressure to the can opening and can lid through a mechanical structure to make them fit tightly together. They can also be used in conjunction with other auxiliary functions to improve packaging quality.

[0003] During protein powder canning, due to the characteristics of protein powder particles and the canning method, the protein powder inside the can is often not packed tightly and has many gaps. After the capping operation, the bumps and vibrations during transportation can easily cause the protein powder inside the can to settle and shift. Changes in the external air pressure and the pressure difference between the inside and outside of the can gradually increase. When the protein powder can is opened, the high-pressure air inside the can is quickly released outward, carrying the loose protein powder particles with it and spraying out, thus forming a powder spraying phenomenon. Therefore, we propose a can sealing machine for protein powder cans. Utility Model Content

[0004] This utility model provides the following technical solution: a sealing machine for protein powder cans, including a conveyor, an mounting plate one fixedly installed at the upper end of the conveyor, two support frames fixedly installed at the side end of the mounting plate one, a connecting rod slidably connected to the upper end of each of the two support frames, the two connecting rods penetrating the side wall of the support frame, the two connecting rods being connected by a linkage structure, an mounting plate two fixedly connected to the bottom end of one of the connecting rods, a compaction plate provided at the bottom end of the other connecting rod, a plurality of through-holes opened at the upper end of the compaction plate, a filter screen fixedly installed on the inner wall of the air outlets, a capping structure fixedly installed at the bottom end of the mounting plate two, and a powder can clamping structure provided at the upper end of the conveyor.

[0005] Preferably, the linkage structure includes a linkage motor, which is fixedly installed on the side of the mounting plate one. A linkage rod one is fixedly installed at the output end of the linkage motor. Both ends of the linkage rod one are rotatably connected to linkage rod two, and one end of each of the two linkage rod two is rotatably connected to the upper end of the two connecting rods respectively.

[0006] Preferably, the capping structure includes a capping motor, which is fixedly connected to the upper end of the mounting plate two. The output end of the capping motor extends to the bottom end of the mounting plate two and is fixedly installed with an inverted U-shaped plate. Cylinder two is fixedly installed on both sides of the inside of the inverted U-shaped plate, and can lid clamping plates are fixedly installed on the opposite ends of the two cylinder two.

[0007] Preferably, the powder tank clamping structure includes a mounting plate three, which is fixedly installed on the upper end of the conveyor. A cylinder one is fixedly installed on the side end of the mounting plate three and the side end of the mounting plate one. A connecting plate is fixedly installed on the opposite side end of the two cylinders one, and two tank clamping plates are fixedly installed on the opposite side end of the two connecting plates.

[0008] Preferably, the cross-section of the can lid clamp and the cross-section of the can clamp are both arc-shaped, and rubber pads are fixedly installed on the side ends of the can lid clamp and the can clamp.

[0009] Preferably, a connecting pipe is fixedly installed on the upper end of the compaction plate, and multiple fixing bolts are provided on the side end of the connecting pipe. Multiple threaded grooves that are compatible with the fixing bolts are opened on the outer surface of one of the connecting rods.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention pre-compacts the protein powder inside the can, reducing voids and residual air, resulting in a tighter fit between the can lid and the can body. This effectively reduces the problem of incomplete sealing caused by residual air, preventing external moisture, oxygen, and impurities from entering the can. The downward pressing structure reduces the settling space of the protein powder inside the can due to transportation vibrations, lowering the risk of powder spraying caused by air pressure changes when opening the can. The uniformly compacted protein powder provides stable support for the can lid, making the sealing machine more evenly stressed during the sealing process and reducing problems such as uneven sealing force and positional deviation caused by loose materials inside the can.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a sealing machine for protein powder cans, including a conveyor 1, an mounting plate 2 fixedly installed at the upper end of the conveyor 1, two support frames 3 fixedly installed at the side end of the mounting plate 2, a connecting rod 4 slidably connected to the upper end of each of the two support frames 3, the two connecting rods 4 penetrating the side wall of the support frame 3, the two connecting rods 4 being connected by a linkage structure 9, an mounting plate 6 fixedly connected to the bottom end of one of the connecting rods 4, a compaction plate 5 provided at the bottom end of the other connecting rod 4, a plurality of through-holes 10 opened at the upper end of the compaction plate 5, a filter screen 11 fixedly installed on the inner wall of the air outlets 10, a capping structure 7 fixedly installed at the bottom end of the mounting plate 6, and a powder can clamping structure 8 provided at the upper end of the conveyor 1.

[0020] In an optional embodiment: the linkage structure 9 includes a linkage motor 91, which is fixedly installed on the side of the mounting plate 2. A linkage rod 92 is fixedly installed at the output end of the linkage motor 91. Both ends of the linkage rod 92 are rotatably connected to linkage rods 93. One end of each linkage rod 93 is rotatably connected to the upper end of the two connecting rods 4.

[0021] It should be noted that the output end of the linkage motor 91 can rotate in both directions. When the positions of the two ends of the linkage rod 92 become higher or lower, under the traction of the linkage rod 93, the two connecting rods 4 move up and down reciprocally, which can compact one protein powder and seal the other protein powder container at the same time.

[0022] In an optional embodiment: the capping structure 7 includes a capping motor 71, which is fixedly connected to the upper end of the mounting plate 6. The output end of the capping motor 71 extends to the bottom end of the mounting plate 6 and is fixedly mounted with an inverted U-shaped plate 72. Cylinders 73 are fixedly mounted on both sides of the inside of the inverted U-shaped plate 72, and can lid clamps 74 are fixedly mounted on the opposite ends of the two cylinders 73.

[0023] It should be noted that the two lid clamps 74, under the action of cylinder 73, can hold the lid in place, and then rotate through the output end of the capping motor 71, causing the lid to rotate and be fastened to the upper end of the protein powder can.

[0024] In an optional embodiment: the powder tank clamping structure 8 includes a mounting plate 3 82, which is fixedly installed on the upper end of the conveyor 1. A cylinder 81 is fixedly installed on the side end of the mounting plate 3 82 and the side end of the mounting plate 2. A connecting plate 83 is fixedly installed on the opposite side end of the two cylinders 81. Two tank clamping plates 84 are fixedly installed on the opposite side end of the two connecting plates 83.

[0025] It should be noted that when both cylinders 81 are started at the same time, the extension or retraction of the extension end of cylinder 81 can move the two connecting plates 83 forward or backward, thereby increasing or decreasing the distance between the two can clamping plates 84, thus clamping the two protein powder cans at the same time.

[0026] In an optional embodiment: the cross-section of the can lid clamp 74 and the cross-section of the can clamp 84 are both arc-shaped, and rubber pads are fixedly installed on the side ends of the can lid clamp 74 and the can clamp 84.

[0027] It should be noted that the shape of the container or lid should be matched to improve the clamping effect. The rubber pad reduces the impact of rigid clamping on the container and lid, and plays a role in cushioning and anti-slip.

[0028] In an optional embodiment: a connecting pipe 12 is fixedly installed on the upper end of the compaction plate 5, and a plurality of fixing bolts 13 are provided on the side end of the connecting pipe 12, and a plurality of threaded grooves adapted to the fixing bolts 13 are opened on the outer surface of one of the connecting rods 4.

[0029] It should be noted that when the compaction plate 5 is damaged or a different compaction plate 5 is replaced, the compaction plate 5 can be separated from the connecting rod 4 or the compaction plate 5 can be fastened to the bottom of the connecting rod 4 by rotating the fixing bolt 13 in both directions, thus improving the overall practicality.

[0030] In practical use, the working principle of this utility model is as follows:

[0031] In use, conveyor 1 can transport protein powder cans in an orderly manner to the position of powder can clamping structure 8. Powder can clamping structure 8 can simultaneously clamp and fix two cans that need to be capped and compacted. Through pneumatic linkage motor 91, the output end of linkage motor 91 can rotate in both directions. When the positions of the two ends of linkage rod 1 92 are raised or lowered, under the traction of linkage rod 2 93, the two connecting rods 4 move one upward and the other downward, thus causing the compaction plate 5 or the capping structure 7 to move one upward and the other downward. At this time, the milk powder in the protein powder can at the bottom can be compacted. The gas in the can can pass through the vent 10, and each vent 10 is equipped with a filter screen 11. The filter screen 11 can block the milk powder and prevent it from being squeezed out. The compacted milk powder comes to the bottom of the capping structure 7. The two cap clamps 74 can hold the cap in place under the action of cylinder 2 73. Then, the output end of the capping motor 71 rotates, which makes the cap rotate and fix it to the top of the protein powder can. The rotation pattern of the capping motor 71 is forward and reverse to avoid the circuit wires of cylinder 2 73 getting tangled.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
