[0011] The present application will be further described in detail below in combination with the accompanying drawings and related contents: Figures 1-3

[0012] ​​​The feeding mechanism of a tea leaf pressing forming machine comprises a rack 10, a horizontally arranged first conveying belt 20 arranged on the rack 10, a plurality of rolling units 30 arranged side by side above the first conveying belt 20 in the width direction of the belt, each rolling unit 30 comprising a roller frame 31 arranged above the first conveying belt 20, a rolling wheel 32 rotatably connected to the roller frame 31 by a bearing, the wheel shaft core direction of the rolling wheel 32 being in the horizontal direction perpendicular to the conveying direction of the first conveying belt 20, the peripheral surface of each rolling wheel 32 being arranged opposite to the belt surface of the first conveying belt 20 and a gap-shaped passage for tea leaves to pass through and be pressed flat being formed between the two, a slanted guide groove 40 with its notch arranged upward being connected to the inlet of the passage, the high-positioned feeding end of the slanted guide groove 40 extending obliquely upward toward the side where the upstream of the first conveying belt 20 is located, the feeding end of the slanted guide groove 40 being connected to a second conveying belt 50 and the belt surface of the second conveying belt 50 being arranged horizontally, the conveying direction of the second conveying belt 50 being consistent with the conveying direction of the first conveying belt 20, and the straightened tea leaves being conveyed from the second conveying belt 50 to the feeding end of the slanted guide groove 40.

[0013] In the above scheme, the second conveying belt 50 is arranged at the feeding end of the slanted guide groove 40 to receive the tea leaves discharged from the fixing and straightening device, the worker can separate and arrange the tea leaves stacked on the second conveying belt 50, and only needs to arrange the tea leaves in a moderate range, without strict limitation on the arrangement position of the tea leaves, so that the overall length direction of the tea leaves is consistent with the conveying direction of the second conveying belt 50, and the leaf tips point to the feeding end of the slanted guide groove 40, the inlet width of the feeding end of the slanted guide groove 40 is obviously larger than the radial dimension of the straightened tea leaves, the tea leaves are automatically conveyed from the second conveying belt 50 to the feeding end of the slanted guide groove 40, and are further guided by the slanted guide groove 40 to slide into the passage formed between the rolling wheel 32 and the first conveying belt 20 to be pressed flat and formed. In this process, the tea leaves do not need to be accurately guided and conveyed to the guide gap formed between the rolling wheel 32 and the first conveying belt 20 by manual operation, and only need to be simply separated and arranged on the second conveying belt 50, which improves the tea feeding efficiency and facilitates manual operation.

[0014] It should be noted that in the prior art, the fixing and straightening device of tea leaves usually comprises a plurality of parallel straightening grooves, the device is connected to the upstream end of the second conveying belt 50, the groove length direction of the straightening grooves is arranged to be consistent with the conveying direction of the second conveying belt 50, the tea leaves discharged from the straightening grooves form rows of tea leaf stacks arranged at intervals on the second conveying belt 50, and the length direction of the tea leaves is basically consistent with the conveying direction of the second conveying belt 50. The worker only needs to separate and simply arrange the tea leaves stacked in each row on the second conveying belt 50 to be spaced apart at the head and tail.

[0015] As a preferred solution, the upstream end of the second conveying belt 50 is provided with a support 51 horizontally arranged along the width direction of the belt, and a receiving trough 52 is arranged on the support 51 along the width direction of the second conveying belt 50 and corresponds to each inclined guide groove 40. The receiving trough 52 is arranged obliquely and located at a low-position discharge end connected to the upstream end of the second conveying belt 50. The receiving trough 52 is arranged with the opening upward. The conveying directions of the receiving trough 52 and the inclined guide groove 40 are consistent with the conveying direction of the second conveying belt 50.

[0016] The purpose of the receiving trough 52 is to better receive the tea discharged by the tea fixation and striping device and guide the tea onto the second conveying belt 50. The tea is guided and constrained by the receiving trough 52, which can effectively form a row of tea piles arranged at intervals on the second conveying belt 50, facilitating the separation and arrangement of the tea by workers.

[0017] Further, a guide plate 53 is arranged at the position of the upper end of the receiving trough 52 on both sides of the groove wall. The guide plate 53 extends upward from the groove cavity of the receiving trough 52 to the outside of the groove cavity, and the surface of the guide plate 53 is in close contact with the groove wall of the receiving trough 52. The upper edges of the adjacent guide plates 53 are connected to each other to form an inverted V-shaped plate structure 531. The V-shaped plate structure 531 covers the spacing area between the adjacent two receiving troughs 52.

[0018] The spacing area between the adjacent two receiving troughs 52 is shielded by the V-shaped plate structure 531, which ensures that the tea discharged by the tea fixation and striping device into the receiving trough 52 will not fall through the spacing area between the adjacent two receiving troughs 52. The tea directly discharged above the spacing area between the adjacent two receiving troughs 52 can be guided into the receiving troughs 52 on both sides, avoiding the tea from falling outside the device and causing waste or the need for emergency treatment.

[0019] As a preferred solution, the two guide plates 53 in the same receiving trough 52 are arranged in a clamping angle type with the upper end far and the lower end close, so that the relative interval span between the upper ends of the two guide plates 53 is larger, which can expand the effective receiving range of the receiving trough 52, and avoid the tea from falling to the outside of the trough from the side of the receiving trough 52.

[0020] As a preferred solution, the slot width of the high-positioned feeding end of the receiving slot 52 is greater than that of the low-positioned discharging end, and the tea leaves falling into the receiving slot 52 can be guided and discharged to the narrow discharging end of the receiving slot 52. When the second conveying belt 50 rotates, the tea leaves guided and fallen from the receiving slot 52 will form a relatively narrow tea leaf row on the second conveying belt 50. On the one hand, this facilitates the separation and arrangement of tea leaves in each tea leaf row, thereby significantly reducing the difficulty of tea leaf arrangement caused by excessively high accuracy requirements of the position of the worker, and on the other hand, this is also to avoid the width of the tea leaf row deviating excessively from the center position of the inclined guide slot 40 (even out of the slot range of the inclined guide slot 40) in the conveying direction of the second conveying belt 50, thereby avoiding the need for substantial adjustment when arranging the tea leaves.

[0021] In addition, in order to improve the smoothness of the falling material, the cross section of the slot cavity of the receiving slot 52 perpendicular to the slot length direction is in the shape of a circular arc, avoiding the existence of edges and corners at the joint position of the slot wall and the slot bottom to affect the falling material.
