Description

TECHNICAL FIELD

[0001] The utility model relates to chemical fertilizer production equipment technical field especially, relates to a chemical fertilizer packing production emptying device. BACKGROUND

[0002] In the production of compound fertilizer, the compound fertilizer particles need to be loaded into the packaging bag for sewing and sealing. Before sewing, the air in the top space of the packaging bag loaded with chemical fertilizer needs to be discharged, which has the following two effects: first, after discharging the air in the top of the packaging bag, it is convenient for the packaging bag to enter the sewing equipment for sewing; second, after discharging the air in the top of the packaging bag, the packaging bag is more fitted to the shape of the chemical fertilizer, which is convenient for carrying and neat stacking. At present, the emptying operation is carried out in the stopped state of the packaging bag loaded with chemical fertilizer. In order to improve the production efficiency, the existing equipment is improved.

The sealing device for chemical fertilizer production includes a support table and a support rod. The support rod is located above the support table. A fixed plate is provided above the support table. The front and rear ends of the fixed plate are fixedly sleeved on the outer surfaces of the two support rods. The left and right sides of the fixed plate are provided with horizontal plates. The mutually close sides of the two horizontal plates are fixedly sleeved with the left and right ends of the two support rods. The sealing device for chemical fertilizer production achieves the effect of pushing the air inside the packaging product out of the upper end during the upward movement of the extrusion wheel by setting the transmission plate, torsional spring, spring telescopic rod, clamping plate and extrusion wheel. The characteristics are that the current sealing device cannot extrude the air inside the packaging, and when there is too much air inside the packaging, the chemical fertilizer inside may deteriorate, thereby affecting the effect of the chemical fertilizer.

[0034] Example 1:

[0035] like Figures 1-3 As shown, a fertilizer packaging production venting device includes a fixed base 10. Two movable frames 30 are installed below the fixed base 10. The two movable frames 30 are connected by a drive mechanism 70 to drive the two movable frames 30 to run in opposite directions. A drive shaft 40 and a driven shaft 50 are rotatably installed at the left and right ends of the movable frames 30, respectively. A drive wheel 41 and a driven wheel 51 are installed at the lower ends of the drive shaft 40 and the driven shaft 50, respectively. A belt 60 is fitted on the drive wheel 41 and the driven wheel 51. The drive shaft 40 is driven by a motor 90 to rotate.

[0036] The fixed base 10 is used to fix and install itself above the production line 200 via a metal structure. The movable frames 30 can move towards or away from each other via the drive mechanism 70. When the movable frames 30 on both sides move away from each other, such as Figure 4 As shown, this facilitates the entry of the fertilizer package 100 into the venting device. Once the fertilizer package 100 enters between the movable frames 30 on both sides of the venting device, the drive mechanism 70 drives the movable frames 30 to move towards each other, causing the movable frames 30 to close together. Figure 5 As shown, the upper end of the fertilizer package 100 is squeezed, causing the internal air to be expelled. During the air expulsion process, the motor 90 drives the drive shaft 40 to rotate, which in turn drives the drive wheel 41 to rotate, which in turn drives the belt 60 to rotate. Thus, while the upper end of the fertilizer package 100 is held by the movable frames 30 on both sides, the fertilizer package 100 can also move downstream along the production line 200, thereby enabling the fertilizer package to be emptied while moving along the production line, thus improving production efficiency.

[0037] In the running time, the running direction of the two sides of the belt is opposite, but the adjacent side of the two sides of the belt 60 is moved from the upstream side of the production line to the downstream side, and the running speed of the belt 60 is consistent with the running speed of the production line.

[0038] It should be noted that the emptying mentioned in the text is not to completely exclude the internal air, but to squeeze out the air on one part of the upper end of the fertilizer package 100, so as to sew and seal the downstream process and carry and stack.

[0039] In this embodiment, the two movable frames 30 can clamp the fertilizer package 100 in a parallel moving manner. For example, the clamping structure of the centering mechanism in CN119429331A can be used.

[0058] When the fertilizer package 100 enters between the two movable frames 30 of the emptying device, the driving mechanism 70 drives the two movable frames 30 to close, as shown in Figure 5 , so as to extrude the upper end of the fertilizer package 100 and discharge the internal air.

[0059] In the above process, the motor 90 drives the driving shaft 40 to rotate, thereby driving the driving wheel 41 to rotate, thereby driving the belt 60 to rotate, so that when the two movable frames 30 clamp the upper end of the fertilizer package 100, the fertilizer package 100 can also move downstream along the production line 200, thereby enabling the fertilizer package to be emptied in the state of moving along the production line, so as to improve the production efficiency.
