Description

Technical Field

[0001] The utility model belongs to the technical field of tea processing, and particularly relates to a tea die closing and forming device. Background Art

[0002] As a traditional form of tea products, tea cakes occupy an important position in the tea market. However, in the traditional tea die closing and forming process, the problem of uneven tea distribution often occurs.

[0003] In order to solve this problem, a Chinese patent with the authorization announcement number CN219007140U discloses an extrusion device for tea processing. First, the tea is placed in the mold, then the mold is rotated, and at the same time, the tea in the mold is preliminarily extruded by a rough pressing mechanism to reduce the gap between the teas. At the same time, the tea during rotation is more evenly distributed, preparing for the forming extrusion. After the preliminary extrusion is completed, the rough pressing mechanism is rotated to the side away from the mold, and then the tea is processed by the extrusion mechanism. At this time, the finished product rate of the processed tea is higher;

[0004] However, due to the characteristics of the tea itself, some teas may be not easy to flow, resulting in the difficulty of achieving uniform distribution of the tea in the mold. This leads to the irregular shape of the tea cake easily caused by uneven tea distribution when the tea is die closed and extruded into a tea cake. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tea die closing and forming device, which can reduce the irregular shape of the tea cake caused by uneven tea distribution when the tea is extruded into a tea cake.

[0006] The technical solution adopted by the utility model is specifically as follows:

[0007] A tea die closing and forming device includes a bottom plate, and a lower die is assembled on the upper side of the bottom plate through a vibration mechanism;

[0008] An air cylinder located above the lower die is fixedly connected to the upper side of the bottom plate through an upper support, and an upper die located above the lower die is fixedly connected to the output end of the air cylinder.

[0009] Further, the vibration mechanism includes a vertical sliding type rotary drive group fixedly connected to the bottom plate and connected to the lower die. A plurality of upper convex parts arranged in an annular array are fixedly connected to the lower side of the lower die, and a plurality of lower convex parts arranged in an annular array are fixedly connected to the upper side of the bottom plate.

[0010] Further, the lower convex part is an inclined block fixedly connected to the upper side of the bottom plate. The vertical section of the inclined block is a right triangle, and one of the right sides of the right triangle is fixedly connected to the bottom plate;

[0011] The upper convex part is a moving wheel fixedly connected to the lower side of the lower die.

[0012] Further, the vertical sliding rotary drive group includes a servo motor fixedly connected to the lower side of the bottom plate. The output end of the servo motor is fixedly connected with a vertically arranged shaft rod. The shaft rod extends to the upper side of the bottom plate, and a shaft sleeve is vertically slidably connected to the outer side of the shaft rod. The upper end of the shaft sleeve is fixedly connected with the axis center of the lower end of the lower die.

[0013] Further, a return spring is assembled inside the shaft sleeve and between the lower die and the shaft rod.

[0014] Further, a reinforcement bracket is fixedly connected to the upper side of the bottom plate, and the lower die is rotatably connected inside the reinforcement bracket.

[0015] The technical effects achieved by the present utility model are as follows:

[0023] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0024] Such as Figures 1-4As shown in the figure, a tea mold closing and forming device includes a bottom plate 1. A lower mold 5 is assembled on the upper side of the bottom plate 1 through a vibration mechanism. After the tea is fed into the lower mold 5, by starting the vibration mechanism to drive the lower mold 5 to vibrate, the tea inside the lower mold 5 can be driven to move under the action of the vibration force, so that the tea that is not easy to flow can be evenly distributed inside the lower mold 5.

[0025] On the upper side of the bottom plate 1, a cylinder 3 located above the lower mold 5 is fixedly connected through an upper support 2. The output end of the cylinder 3 is fixedly connected with an upper mold 4 located above the lower mold 5. At this time, by starting the cylinder 3, the upper mold 4 can be driven to move vertically, so that the upper mold 4 moves into the lower mold 5 to press the tea inside the lower mold 5, complete the mold closing of the upper mold 4 and the lower mold 5, and extrude the tea inside the lower mold 5 into a tea cake.

[0026] As Figures 1-3 shown in the figure, the vibration mechanism includes a vertically sliding rotary drive group fixedly connected to the bottom plate 1 and connected to the lower mold 5. The vertically sliding rotary drive group can drive the lower mold 5 to rotate, and the lower mold 5 can move vertically. A plurality of upper convex parts arranged in an annular array are fixedly connected to the lower side of the lower mold 5, and a plurality of lower convex parts arranged in an annular array are fixedly connected to the upper side of the bottom plate 1. When the vertically sliding rotary drive group drives the lower mold 5 to rotate, when the upper convex part contacts the lower convex part, the lower mold 5 will move upward. When the upper convex part and the lower convex part are separated, the lower mold 5 will automatically fall under the action of gravity, so that the lower mold 5 can vibrate. And when a plurality of convex parts and the lower convex parts apply kinetic energy to the lower mold 5, the force inside the lower mold 5 is relatively uniform, so that the tea inside the lower mold 5 can be evenly distributed better.

[0027] As Figures 2-4 shown in the figure, the lower convex part is an inclined block 7 fixedly connected to the upper side of the bottom plate 1. The vertical section of the inclined block 7 is a right triangle, and one of the right sides of the right triangle is fixedly connected to the bottom plate 1. At this time, when the upper convex part moves on the inclined surface of the inclined block 7, it will drive the lower mold 5 to move upward. When the upper convex part is separated from the inclined block 7, due to the certain height difference between the upper convex part and the bottom plate 1, the vibration amplitude of the lower mold 5 will be increased.

[0028] As Figures 2-4 shown in the figure, the upper convex part is a moving wheel 8 fixedly connected to the lower side of the lower mold 5. At this time, through the rotation of the moving wheel 8, the wear of the upper convex part when being driven by the lower mold 5 to revolve can be reduced.

[0029] As Figures 2-4As shown in the figure, the vertical sliding rotary drive group includes a servo motor 9 fixedly connected to the lower side of the bottom plate 1. The output end of the servo motor 9 is fixedly connected with a vertically arranged shaft rod 10. The shaft rod 10 extends to the upper side of the bottom plate 1, and a shaft sleeve 11 is vertically slidably connected to the outer side of the shaft rod 10. The upper end of the shaft sleeve 11 is fixedly connected to the center of the lower die 5. At this time, by starting the servo motor 9, rotational kinetic energy can be input to the lower die 5, and through the sliding of the shaft rod 10 and the shaft sleeve 11, the up and down movement of the lower die 5 can be adapted.

[0030] In order to enhance the vibration effect, a return spring 12 is assembled inside the shaft sleeve 11 and between the lower die 5 and the shaft rod 10. When the moving wheel 8 falls from the inclined block 7, the downward movement of the lower die 5 will squeeze the return spring 12. When the return spring 12 is squeezed, it will deform and store energy, so that the reset performance of the return spring 12 drives the lower die 5 to move up and down multiple times again, enhancing the vibration effect of the lower die 5.

[0031] A reinforcement bracket 6 is fixedly connected to the upper side of the bottom plate 1. The lower die 5 is rotatably connected inside the reinforcement bracket 6. Through the reinforcement bracket 6, the stability of the lower die 5 can be greatly improved, and the torsion force on the shaft rod 10 and the shaft sleeve 11 can be reduced.

[0032] The working principle of the present utility model is as follows:

[0033] After feeding the tea leaves into the lower die 5, by starting the vibration mechanism to drive the lower die 5 to vibrate, the tea leaves inside the lower die 5 can be driven to move under the action of the vibration force, so that the tea leaves that are not easy to flow can be evenly distributed inside the lower die 5;

[0034] Starting the cylinder 3 can drive the upper die 4 to move vertically, making the upper die 4 move into the lower die 5 to press the tea leaves inside the lower die 5, thus completing the clamping of the upper die 4 and the lower die 5 and squeezing the tea leaves inside the lower die 5 into tea cakes.

[0035] In summary, through the kinetic energy of vibration applied to the lower die 5 in this technical solution, the tea leaves that are not easy to flow can be evenly distributed inside the lower die 5. When the upper die 4 and the lower die 5 squeeze the tea leaves into tea cakes, the phenomenon of irregular tea cake shapes caused by uneven distribution of tea leaves can be reduced.

[0036] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special description and limitation.
