Description

Technical Field

[0001] The invention relates to a sweet potato vine quick bundling and packaging device. Background Art

[0002] The sweet potato vines are bundled after harvesting and dried naturally or artificially in the field. After drying, the bundled sweet potato vine rolls need to be packaged for easy storage to avoid dispersion.

[0003] The packaging equipment in the prior art adopts a turntable, on which the sweet potato vine rolls are placed. The rotation of the turntable drives the sweet potato vine rolls to rotate, and then the film is passively wound to complete the packaging work.

[0004] We found in actual operation that this operation mode has the following disadvantages:

[0005] First, the sweet potato rolls are placed only by gravity, so they can only be rotated at a low speed when packed. If the rotation speed is too fast, the sweet potato rolls will be thrown out.

[0006] Second, when the sweet potato vine rolls are being packaged, the initial contact force between the film and the sweet potato vine rolls is insufficient, which results in the film often being unable to be smoothly wrapped around the sweet potato vine rolls and requiring manual assistance.

[0007] Third, the film has a poor unfolding degree, which causes the film to be stretched thin during the winding process, resulting in a poor packaging effect.

[0008] Based on the above problems, we designed a sweet potato vine rapid bundling and packaging equipment with stable rotation, smooth film unfolding and higher packaging efficiency. Summary of the invention

[0037] See also Figure 1 The sweet potato vine quick bundling and packaging equipment shown in the figure includes a support body 1, a lower rotating device 2 installed through the support body 1, and an upper clamping device 3 installed through the support body 1 and cooperating with the lower rotating device 2. The packaged sweet potato vine roll is clamped between the lower rotating device 2 and the upper clamping device 3. A movable film releasing device 4 is also installed through the support body 1. The roll film used for packaging the sweet potato vines is unrolled through the movable film releasing device 4, and the movable film releasing device 4 is cooperated with a film pressing device 5.

[0038] In the above technical scheme, the sweet potato vine rolls bundled by the baling machine are placed on the top of the lower rotating device 2, and then the upper clamping device 3 is pressed down to press the sweet potato vine rolls, and then one end of the film is pressed on the sweet potato vine roll by the film pressing device 5, and then the sweet potato vine rolls are driven to rotate by starting the lower rotating device 2. The rotation of the sweet potato vine roll drives the film to be pulled out from the movable film releasing device 4, and the pulled out film is wrapped around the outside of the sweet potato vine roll.

[0039] During the unwinding process, the film is completely wound around the outside of the sweet potato vine roll by changing the height of the movable film unwinding device 4 .

[0040] After completing the film rolling work, cut off the film and remove the packaged sweet potato vine rolls.

[0041] See also Figure 2 , Figure 3 and Figure 4 As shown, the bracket body 1 includes a base plate 101, and a vertical bracket 102 fixed to the top of the base plate 101, a side bracket 103 and an auxiliary bracket 104 are welded through the vertical bracket 102, the upper clamping device 3 is installed through the side bracket 103, and is guided by the auxiliary bracket 104, the movable film placing device 4 is installed through the auxiliary bracket 104, a shaft sleeve 106 is arranged on the top of the base plate 101, and the lower rotating device 2 is rotatably installed through the shaft sleeve 106.

[0042] The above technical solution is mainly for completing the installation of various parts.

[0043] The bottom plate 101 and the vertical bracket 102 are fixed by welding.

[0044] See also Figure 1 and Figure 2 As shown, the lower rotating device 2 includes a turntable 201 and a driving motor 204. A rotating shaft 202 is provided at the bottom of the turntable 201. The lower end of the rotating shaft 202 is inserted into the sleeve 106. A bearing is matched between the rotating shaft 202 and the sleeve 106.

The vertical bracket 102 passes through the inner side of the transmission belt 206. The turntable 201 corresponds to the upper clamping device 3.

[0045] In the above technical solution, the transmission belt 206 is a synchronous toothed belt, and the corresponding driven pulley 203 and the driving pulley 205 are synchronous toothed pulleys.

[0046] The torque is outputted by the driving motor 204 and transmitted through the transmission belt 206 to drive the turntable 201 to rotate. The rotation of the turntable 201 drives the sweet potato vine rolls to rotate to complete the packaging work.

[0047] See also Figure 3 and Figure 5 As shown, the upper clamping device 3 includes an electric push rod 301, which is fixed by the side bracket 103. The end of the auxiliary bracket 104 is provided with a guide sleeve 144.

[0048] In the above technical solution, the extension of the electric push rod 301 causes the movable pressing plate 304 to press down on the upper part of the sweet potato vine circle. With the continuous downward pressure, the insertion rod 305 is inserted into the sweet potato vine roll to prevent the sweet potato vine roll from slipping and sliding out during packaging.

[0049] After packaging is completed, the electric push rod 301 retracts, and under the action of the spring 308, the movable pressing plate 304 moves downward, so that the insertion rod 305 is separated from the sweet potato vine roll, thereby preventing the sweet potato vine roll from being pulled up.

[0050] See also Figure 5 As shown, the lower end of the insertion rod 305 is a spike end 355 , and when the movable pressing plate 304 moves downward to the limit position, the spike end 355 is exposed to the outside of the movable pressing plate 304 .

[0051] The provision of the spike end 355 can provide a fixing effect when the movable pressing plate 304 just contacts the sweet potato vine roll.

[0052] See also Figure 1 and Figure 4 As shown, the movable film placing device 4 includes a first electric push rod 401 and a winding roller 402, and the winding roller 402 is rotatably installed on the movable end of the first electric push rod 401, and the first electric push rod 401 is located on the outside of the lower rotating device 2 and the upper clamping device 3, and the upper end of the first electric push rod 401 is fixedly connected to the auxiliary bracket 104, and the film pressing device 5 is fixed to the movable end of the first electric push rod 401.

[0053] In the above technical solution, the movement of the first electric push rod 401 drives the roller 402 to move up and down, thereby changing the height of the film roll, so that the film can completely wrap around the outside of the sweet potato vine roll.

A rotating shaft 508 is arranged on the bottom of the U-shaped plate 503, away from the sealing plate 504, and a bearing is cooperated between the rotating shaft 508 and the U-shaped plate 503. A film pressing roller 509 is fixedly connected to the lower end of the rotating shaft 508.

[0057] In the above technical solution, the U-shaped plate 503 is displaced along the frame plate 501, so that the film pressing roller 509 always fits the outer surface of the sweet potato vine roll, and the film is firmly pressed against the surface of the sweet potato vine roll, so that when the sweet potato vine roll rotates, there is enough friction to pull the film off the roller 402 to complete the winding of the film.

[0058] In the above technical solution, a plurality of transition rollers 512 are provided, and the film is passed around the outside of the transition rollers 512, so that the unwinding of the film is more orderly.
