Abstract
Description
Technical Field
[0001] The utility model relates to the field of tea processing machinery, in particular to a tea rolling machine. Background Art
[0002] After being picked, tea leaves need to go through multiple processing steps such as withering, killing green leaves, rolling and twisting before they can become tea. Rolling and twisting is a crucial step in the tea processing process. Among them, the rolling step makes the tea leaves into strips, and the twisting step breaks the tea leaves cells and squeezes out the tea juice. The tea juice adheres to the surface of the tea strips, increasing the viscosity and facilitating the formation of the tea leaves' appearance.
[0003] Nowadays, the processing of fresh tea is usually completed automatically by the production line. The tea that has been processed in the previous steps is transported to the rolling machine through a conveyor belt. After being rolled in the rolling machine, it is discharged from the rolling machine and enters the next processing step, finally becoming tea that can be sold.
[0004] A tea rolling machine with application number CN2022208673387 includes a rolling disk, and a plurality of spirally distributed rolling ribs are provided on the upper surface of the rolling disk. The rolling ribs improve the rolling efficiency of the tea leaves. However, after the tea leaves are rolled, when the tea leaves on the rolling disk are discharged from the rolling disk, the tea leaves tend to accumulate at the rolling ribs, making it easy for the tea leaves to be left behind when the tea leaves are unloaded. Utility Model Content
[0005] Based on the above description, the utility model provides a tea rolling machine to solve the problem that when tea is processed using a production line, the rolled tea leaves are easily accumulated at the rolling ribs, leaving a lot of tea leaves when unloading.

[0007] The present application provides a tea rolling machine, comprising a rolling disc, wherein a discharge hole is provided in the middle of the rolling disc, and a plurality of discharge channels are provided on the side wall of the discharge hole, and the discharge channels penetrate through the outer side wall of the rolling disc;
[0008] A lifting plate capable of blocking the discharge hole is arranged in the discharge hole, and the lifting plate can be moved to be coplanar with the twisting plate, or moved to a surface to be connected with the discharge channel.
[0009] On the basis of the above technical solution, the present invention can also be improved as follows.
[0010] Furthermore, the turntable surface is provided with a slope surface which gradually inclines from the edge of the turntable toward the discharge hole.
[0011] Furthermore, the thickness of the lifting plate gradually becomes thinner from the center to the edge, and the side walls of the lifting plate away from the kneading cylinder are in the same horizontal plane.
[0012] Furthermore, the bottom wall of the discharge channel is provided with a downward inclined slope in a direction away from the discharge hole.
[0013] Furthermore, a driving component is provided on the lifting plate for driving the lifting plate to move in the discharge hole, and the driving component drives the lifting plate to move until the edge of the lifting plate is coplanar with the bottom wall of the discharge channel, or drives the lifting plate to move until the edge of the lifting plate is coplanar with the peripheral side of the discharge hole.
[0014] Furthermore, a support portion is provided between two adjacent discharge channels, and the thickness of the support portion gradually increases in a direction away from the discharge hole.
[0015] Furthermore, a kneading cylinder is arranged above the twisting disk, and the kneading cylinder is used for kneading the tea leaves on the twisting disk, and a plurality of kneading ribs are arranged on the end surface of the kneading cylinder that contacts the tea leaves.
[0016] Furthermore, a feed port is provided on the side wall of the rolling cylinder, and a chute is fixed around the feed port, and the chute is used to receive the tea leaves transmitted to the rolling machine.
[0017] Furthermore, the side wall of the chute is arc-shaped, and the width of the chute gradually widens in the direction away from the feed port.
[0018] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0019] 1. The present application sets a discharge hole in the middle of the twisting disc and a discharge channel inside the twisting disc, and also sets a lifting disc that can be raised and lowered, so that after the tea rolling machine of the present application has finished rolling the tea leaves, the lifting disc can be driven to move to communicate with the discharge channel, thereby realizing automatic discharge;
[0020] 2. The present application arranges the kneading ribs on the bottom wall of the kneading cylinder to improve the kneading efficiency of the tea leaves. At the same time, the kneading ribs are not arranged on the twisting plate so that the tea leaves can be collected more smoothly into the discharge hole to complete the discharge;

[0030] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0032] A tea rolling machine disclosed in the embodiment of the present application, referring to Figure 1 A tea rolling machine includes a rolling disc 1 and a rolling cylinder 4, wherein the rolling cylinder 4 is arranged above the rolling disc 1, and the diameter of the rolling cylinder 4 is smaller than the diameter of the rolling disc 1. A power member 6 for driving the rolling cylinder 4 to rotate on the rolling disc 1 is fixed on the rolling cylinder 4, and the power member 6 is a prior art and will not be described in detail here.
[0033] When the tea leaves are rolled, the tea leaves are first placed into the rolling cylinder 4. There is a gap between the rolling cylinder 4 and the twisting disk 1. The distance between the twisting disk 1 and the rolling cylinder 4 can be adaptively adjusted according to the rolling requirements. The rolling of the tea leaves between the rolling cylinder 4 and the twisting disk 1 is achieved by rotating the rolling cylinder 4 around the twisting disk 1.
[0034] Reference Figure 2 and Figure 3 A discharge hole 11 is opened through the middle of the twist disc 1, and a plurality of discharge channels 12 are opened through the side wall of the discharge hole 11, wherein the discharge hole 11 is opened along the thickness direction of the twist disc 1, and the discharge channels 12 extend along the radius direction of the twist disc 1, and the discharge channels 12 are located inside the twist disc 1.
[0035] Reference Figure 3 A lifting plate 2 is provided in the discharge hole 11, and the diameter of the lifting plate 2 matches the diameter of the discharge hole 11, so that the discharge hole 11 is blocked by the lifting plate 2; a driving component 3 is provided on the side of the lifting plate 2 away from the kneading cylinder 4, and the driving component 3 can specifically be a hydraulic cylinder, which can drive the lifting plate 2 to move in the discharge hole 11.
[0036] Reference Figure 3 By moving the lifting plate 2 so that the lifting plate 2 is coplanar with the upper surface of the twisting plate 1, the tea leaves can be rolled on the twisting plate 1; when the tea leaves are rolled, refer to Figure 4 The lifting plate 2 can be lowered until the plate surface is coplanar with the bottom wall of the discharge channel 12, so that the rolled tea leaves can fall into the discharge hole 11 and be discharged from the twisting plate 1 along the discharge channel 12, thereby realizing automatic discharge of the tea leaves and improving the degree of automation of tea processing.
[0037] Further, see Figure 3 The surface of the twisting disc 1 is provided with a slope surface which gradually inclines from the edge of the twisting disc 1 to the discharge hole 11.
[0038] By arranging a sloped surface on the surface of the twisting disk 1, the tea leaves can be gathered into the discharge hole 11 along the sloped surface under the push of the kneading cylinder 4 during discharge, thereby reducing the situation where the tea leaves gather on the twisting disk 1 during discharge, and all the kneaded tea leaves can be pushed into the discharge hole 11 as much as possible.
[0039] Further, see Figure 3 The thickness of the lifting plate 2 gradually becomes thinner from the center to the edge, and the side walls of the lifting plate 2 away from the kneading cylinder 4 are in the same horizontal plane, so that the surface of the lifting plate 2 has a slope from the center toward the edge; at the same time, the bottom wall of the discharge channel 12 is provided with a downward slope in the direction away from the discharge hole 11.
[0040] When the tea leaves are discharged from the rolling machine, the lifting plate 2 moves to a position coplanar with the bottom wall of the discharge channel 12. At this time, the tea leaves that fall from the discharge hole 11 partially fall onto the lifting plate 2, and partially fall directly into the discharge channel 12. By setting a slope from the center to the edge on the surface of the lifting plate 2, the tea leaves that fall on the lifting plate 2 can be moved to the discharge channel 12 and discharged from the rolling machine along the discharge channel 12. An inclined slope is set on the bottom wall of the discharge channel 12 so that the tea leaves can slide out of the discharge channel 12 along the discharge channel 12, reducing the possibility of tea leaves accumulating in the discharge channel 12; in a more preferred embodiment, the inclined slope of the discharge channel 12 is greater than the inclined slope of the surface of the lifting plate 2.
[0041] Reference Figure 5 The structure between any two adjacent discharge channels 12 is a support portion 13, the thickness of the support portion 13 gradually becomes thicker in the direction away from the discharge hole 11, and the end surface of the support portion 13 close to the discharge hole 11 is polished so that the end surface is arc-shaped or conical, thereby guiding the tea leaves from the end surface of the support portion 13 into the discharge channel 12, reducing the possibility of tea leaves accumulating on the support portion 13.
[0042] Further, see Figure 6 In the present application, a plurality of kneading ribs 42 are arranged on the end face of the kneading cylinder 4 close to the twisting disk 1. The kneading of tea leaves is achieved by arranging the kneading ribs 42 on the end face of the kneading cylinder 4. The wall thickness of the kneading cylinder 4 is reasonably set, and then the length of the kneading ribs 42 is adjusted to meet the kneading requirements.
[0043] Compared with the traditional kneading machine which sets the kneading ribs 42 on the twisting disk 1, the kneading machine of the present application sets the kneading ribs 42 on the end face of the kneading cylinder 4. On the one hand, since the tea leaves are kneaded by the rotation of the kneading cylinder 4, setting the kneading ribs 42 on the kneading cylinder 4 can increase the contact time between the tea leaves and the kneading ribs 42, thereby improving the kneading efficiency; on the other hand, the kneading ribs 42 are not set on the twisting disk 1, so that the surface of the twisting disk 1 is smoother, so that the tea leaves can slide more easily into the discharge hole 11 and be discharged.
[0044] In addition, refer to Figure 1 and Figure 6 The power member 6 fixed to the kneading cylinder 4 needs to drive the kneading cylinder 4 to rotate. At the same time, according to the kneading requirements, the distance between the kneading cylinder 4 and the twisting disc 1 needs to be adjusted. Therefore, a feed port 41 is provided on the side wall of the kneading cylinder 4 of the present application, and a chute 5 is fixed around the feed port 41. Preferably, the side wall of the chute 5 is arc-shaped, and the width of the chute 5 gradually widens in the direction away from the feed port 41. When adding tea leaves into the kneading cylinder 4, it is only necessary to pour the tea leaves into the chute 5, and the tea leaves can be accurately introduced into the kneading cylinder 4 along the chute 5.
[0045] When the kneading cylinder 4 of the present application is placed in a production line for automatic tea processing, the volume of the chute 5 can be increased so that no matter where the kneading cylinder 4 moves to, the discharge port of the previous process is located above the chute 5, thereby discharging the tea leaves processed in the previous process into the kneading cylinder 4 to realize the kneading processing of the tea leaves.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
