The chute has a slope, and the blueberries can roll down through the chute, thus avoiding direct dropping and damage. However, the rolling of the blueberries will cause the loss of the fruit powder on the surface of the blueberries, thereby affecting the quality of the blueberries. Summary of the Utility Model

Detailed Embodiments

[0030] Next, the present utility model will be described in detail with reference to the accompanying drawings. What is described herein is only the preferred embodiment of the present utility model, and those skilled in the art can think of other ways to implement the present utility model based on the preferred embodiment, and such other ways also fall within the scope of the present utility model.

[0031] Embodiment

[0032] Please refer to Figures 2 - 7, this embodiment provides a blueberry conveying mechanism, including a frame 100 and a conveying body 200, which is connected to the frame 100. The frame 100 is located below the conveying body 200 and serves to support the conveying body 200. The conveying body 200 includes a conveyor belt 220 and a number of driven rollers 230, which are arranged relatively far apart. Generally, there are two driven rollers 230, which are respectively arranged at the front and rear ends in the conveying direction of the conveying body 200. The conveyor belt 220 is wound around the two driven rollers 230 at the front and rear to form a conveying platform. The output end 210 of the conveying body 200 extends to the outside of the end of the frame 100, so that the conveying body 200 and the frame 100 are arranged in a gradient structure, and there is a gradient space 300 between the output end 210 and the end of the frame 100. The gradient space 300 is used to connect the conveying platform of the next section of the conveying mechanism, and the conveying platform of the next section of the conveying mechanism is close to the bottom of the output end 210. When the distance between the conveying plane of the upper section of the conveying body 200 and the conveying plane of the next section of the conveying mechanism remains unchanged, reducing the diameter of the driven roller 230 can reduce the distance from the conveying plane of the conveying body 200 to the conveying plane of the next section of the conveying mechanism, thereby reducing the drop of blueberries from the upper section of the conveying mechanism to the next section of the conveying mechanism and reducing the risk of blueberries being bruised. Moreover, it replaces the slide plate structure in the prior art, reduces unnecessary rolling of blueberries, keeps the fruit powder on the surface of blueberries, and maintains the quality of blueberries.

[0033] It should be noted that the driven rollers 230 used in the blueberry conveying mechanisms on the market at present are all conventional rollers. As Figure 8 shown, the diameter is relatively large, generally 65 mm. The driven roller 230 in this embodiment is a roller with a thinner diameter, and the diameter is 28 mm - 38 mm, and the optimal choice is 33 mm. Of course, within this range, 28 mm, 30 mm, 32 mm, 33 mm, 34 mm or 35 mm can be selected according to the actual situation. Using the driven roller 230 with a diameter of 33 mm in this embodiment can greatly reduce the drop of blueberries when transitioning from different sections of the conveying body 200, reduce the risk of bruising, achieve smooth material during the entire conveying process, and prevent fruit damage during the segmented transition. Moreover, it greatly reduces the production cost, improves the production efficiency, and enhances the competitiveness of the packaging machine.

[0034] Specifically, as Figure 4 , Figure 5 and Figure 6As shown, the conveyor 200 further includes a conveyor frame 240, and two driven rollers 230 are respectively installed on the input side and the output side of the conveyor frame 240. The output side refers to the side close to the output end 210 of the conveyor 200, and the input side is the side opposite to the output side. The driven roller 230 includes a shaft core 231 and a drum 232. The shaft core 231 is installed on the conveyor frame 240, and the drum 232 is rotatably connected to the shaft core 231 and can rotate around the axial direction of the shaft core 231. The conveyor belt 220 is arranged around the drum 232, and the rotation of the drum 232 drives the conveyor belt 220 to move to complete the conveying of blueberries. It should be noted that the diameter of the drum 232 is 33 mm.

[0035] Furthermore, as Figure 6 and Figure 7 shown, the drum 232 is divided into several segments, and there is a gap between adjacent drums 232, and the shaft core 231 is exposed at the gap. The drum 232 has a relatively small diameter and relatively weak strength. By dividing the drum 232 into several segments, stress concentration can be reduced, its anti-deformation ability can be increased, and thus the structural strength can be improved. The conveyor frame 240 includes a support beam 241, and the support beam 241 is arranged perpendicular to the conveying direction of the conveyor 200. The support beam 241 is connected to the shaft core 231 at the gap through a support plate 242. The position of the support beam 241 close to the output end 210 provides support for the end of the conveyor frame 240, and the support plate 242 provides support for the shaft core 231, which can increase the overall structural strength of the conveyor 200.

[0036] The drum 232 needs to be rotated around the shaft core 231 through a driving mechanism. There are various driving methods to realize the rotation of the drum 232. In an embodiment of the present application, as Figure 3 and Figure 4 shown, grooves 233 are provided at both ends of the drum 232 close to the two ends, and the frame 100 is equipped with a driving mechanism, and the driving mechanism is in transmission cooperation with the grooves 233 through a transmission belt 250. The grooves 233 at both ends of the drum 232 close to the two ends are all in cooperation with the transmission belt 250, which increases the smoothness of the movement of the driven roller 230 and is beneficial to maintaining the conveying quality of blueberries.

[0037] Correspondingly, as Figure 4 shown, there are two groups of transmission belts 250, and the two groups of transmission belts 250 are arranged on both sides of the conveyor belt 220, and the transmission belts 250 are arranged higher than the plane of the conveyor belt 220. The two groups of transmission belts 250 are exactly located at the edge positions on both sides of the conveyor belt 220, and the transmission belts 250 are higher than the plane of the conveyor belt 220, which can block blueberries and prevent blueberries from falling from both sides of the conveyor belt 220 during the conveying process, avoiding losses.

[0038] The driving mechanism is a relatively mature technology, and there are many choices on the market. In an embodiment of the present application, as Figure 3As shown, the driving mechanism includes a motor 400, a coupling, and a transmission shaft. The motor 400 drives the transmission shaft to rotate through the coupling, and the transmission belt 250 is connected to the transmission shaft. The transmission shaft transmits power to the transmission belt 250, and the transmission belt 250 drives the driven roller 230 to rotate, thereby moving the conveyor belt 220. The frame 100 is provided with a housing 110, and the housing 110 covers the driving mechanism. The housing 110 prevents blueberries or sundries from falling into the driving mechanism and avoids failures of the driving mechanism. The housing 110 is provided with a through slot 111 through which the transmission belt 250 passes.
