Description

Technical Field

[0002] Quantitative bagging equipment is able to load materials into bags according to the weight set by the user and seal the edges. This type of equipment generally weighs the materials first, then places the bag on the discharge port, pours the set weight of material into the bag, and then seals the bag mouth.

[0003] However, in actual operation, the bag is generally opened manually, and then the bag is loaded to the discharge port and then clamped.

[0033] In this embodiment, the specific working principle is as follows: when the device is used, the bag is first placed between the clamping blocks 20, and then the second telescopic motor 16 drives the connecting rod 17 to rotate inward, so that the clamping block 20 clamps the bag surface, and then the bag surface is sucked by the suction nozzle 22, and then the second telescopic motor 16 contracts, driving the connecting rod 17 to rotate outward, at this time the bag is opened by suction, and then the first telescopic motor 9 contracts, thereby driving the first connecting plate 11 to move upward, thereby driving the clamping block 20 to move upward through the fixed plate 12, so that the bag mouth opened by the bag is sleeved on the outlet. The surface of the material funnel 6 is touched, and then the second telescopic click 16 is extended, thereby driving the clamping block 20 to move inward through the action of the connecting rod 17, so that the clamping belt 18 clamps the surface of the bag, so that in this way, there is no need to manually open the bag mouth and then clamp it, and the automatic operation of bag mouth opening and clamping can be realized. In this way, the overall efficiency of fertilizer bagging of the equipment can be improved. Before clamping the bag mouth, the fertilizer is poured into the feeding structure and then enters the quantitative weighing structure. When the weight reaches the predetermined value, the fertilizer is poured into the bag through the discharge funnel 6.

[0034] According to the above, how does the quantitative weighing structure achieve quantitative weighing? For details, please refer to Figure 3 and Figure 7It can be seen that the quantitative weighing structure includes a second box body 5 installed on the frame structure, and the inner surface of the second box body 5 is symmetrically provided with a third mounting block 57, a weighing sensor 56 is installed on the upper end of the third mounting block 57, and a fixing block 55 is installed on the upper end of the weighing sensor 56.

When the fertilizer enters the second discharge box 59, the weight of the fertilizer can be detected by the weighing of the weighing sensor 56, and then the discharge is carried out through the switch structure. When the set weight is not reached, the switch structure is in a closed state.

[0035] According to the above, when the weight reaches the set value, how to open the switch structure? For details, please refer to Figure 3 It can be seen that the switch structure includes a fourth telescopic motor 49 symmetrically installed on the surface of the second discharge box 59, and second connecting plates 52 are installed on the left and right sides of the second discharge box 59.

Connecting columns 53 are connected at both ends of the connecting block 51, and one end of the connecting column 53 is connected to the discharge door 54. When the weighing sensor 56 detects that the weight of the fertilizer reaches a set value, the fourth telescopic motor 49 drives the telescopic column 50 to move downward, and then the action of the connecting column 53 drives the discharge door 54 to expand outward, thereby completing the opening of the opening, otherwise it is closed.

The vibrator 44 has a first discharge box 45 connected to its upper end, and the second discharge plate 43 extends into the first discharge box 45 with an opening. When the weighing value gradually approaches the set value, the third telescopic motor 46 drives the second connecting shaft 48 to move in the counterclockwise direction through the extension of the telescopic end, so that the blocking plate 47 rotates counterclockwise to block the opening of the first discharge plate 42, and then the vibrator 44 starts to vibrate, so that the fertilizer extends through the second discharge plate 43 to the first discharge box 45 with an opening and falls a small amount.
