The components of tea include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages made from tea are one of the three major beverages in the world. During the production and processing of tea, in order to facilitate the transportation and storage of tea, tea often needs to be packaged and processed, so a packaging machine is required to automatically package and process tea.

[0003] When the related packaging machine is in use, usually the tea packaging boxes used for packaging tea are automatically transported to the lower part of the material box filled with tea through a conveyor belt, and then the filling mechanism in the material box is started to fill the tea into the lower packaging boxes, so as to achieve the effect of automatic filling and packaging of tea.

[0004] However, when using the above method, since the tea packaging boxes are prone to shift and tilt during the movement when being transported by the conveyor belt, it is difficult for the tea packaging boxes to accurately move to the lower part of the material box for filling and packaging. Usually, limiting baffles are installed on both sides of the conveyor belt to limit the movement of the packaging boxes. Affected by factors such as the need for fixed installation of the baffles, only tea packaging boxes of a fixed size can be limited in movement.

Detailed Description of the Embodiment

[0023] The following will Figures 1-4 further describe the present application in detail.

[0024] An embodiment of the present application discloses an automatic tea packaging machine. Referring to Figure 2 Figure 3 , an automatic tea packaging machine includes a workbench 1 and a tea packaging box 2, wherein the tea packaging box 2 is located on the top of the workbench 1. A filling mechanism 3 for automatic filling is arranged on the top of the workbench 1. A feeding mechanism 4 for transporting the tea packaging box 2 is also arranged on the top of the workbench 1, and further includes

[0025] a positioning fixture 5, which is located on the top of the workbench 1 for limiting and positioning tea packaging boxes 2 of different sizes;

[0026] The limiting mechanism 7 is located at one end of the positioning fixture 5 for limiting and guiding the tea packaging box 2;

[0027] The positioning fixture 5 includes two positioning clamping plates 501 and an adjustment assembly 6. One end of the two positioning clamping plates 501 is installed on the top of the workbench 1 through the adjustment assembly 6;

[0028] The adjustment assembly 6 includes two fixed blocks 601, two telescopic cylinders 602, two electric push rods 603 and two telescopic rods 604. The bottoms of the two fixed blocks 601 are symmetrically fixedly connected to the top of the workbench 1. The side walls of the two telescopic cylinders 602 are respectively fixedly connected to the centers of the tops of the two fixed blocks 601. The two electric push rods 603 are respectively fixedly connected to one end of the two telescopic cylinders 602. The two telescopic rods 604 are respectively slidably connected to the inner sides of the other ends of the two telescopic cylinders 602. The output ends of the two electric push rods 603 are fixedly connected to one end of the two telescopic rods 604 through sliding through one end of the two telescopic cylinders 602. One end of the two positioning clamping plates 501 is respectively fixedly connected to the other ends of the two telescopic rods 604;

[0029] The filling mechanism 3 includes a support frame 301 and a filling tank 302. The bottom of the support frame 301 is fixedly connected to the top of the workbench 1. The side wall of the filling tank 302 is fixedly connected to the top of the support frame 301;

[0030] The feeding mechanism 4 includes two belt pulleys 401, a motor 402 and a conveyor belt 403. The two belt pulleys 401 are symmetrically rotatably connected to the inner side of the top of the workbench 1. The motor 402 is fixedly connected to the inner wall of the workbench 1. The output end of the motor 402 is fixedly connected to one end of one of the belt pulleys 401. The conveyor belt 403 is installed between the two belt pulleys 401;

[0031] In this embodiment, first, according to the size of the tea packaging box 2, two electric push rods 603 controlled by the same control system are set to start telescoping, thereby driving the two telescopic rods 604 connected thereto to be stressed and telescopically slide inside one end of the two telescopic cylinders 602 supported and fixed by the two fixed blocks 601. By the telescopic sliding movement of the telescopic rods 604, the two positioning clamping plates 501 connected thereto are driven to be stressed and move, open or close on the top of the set conveyor belt 403. By the movement, opening or closing of the two positioning clamping plates 501, the size of the clamped and positioned object is adjusted and changed, so as to facilitate adjusting and changing the size of the clamped and positioned object according to the use requirements, thereby facilitating clamping and limiting the positioning of tea packaging boxes 2 of different sizes, without replacing different devices for limiting and positioning, effectively improving the convenience of use. At this time, the tea packaging box 2 is placed on the set conveyor belt 403, and then the motor 402 is started to provide a force to drive one of the belt pulleys 401 connected thereto to rotate under stress. By the rotation of one of the belt pulleys 401 and the cooperative rotation of the other belt pulley 401, the set conveyor belt 403 is driven to rotate and move. By the rotation and movement of the conveyor belt 403, the tea packaging box 2 placed thereon is driven to move and be conveyed. At this time, by the tea packaging box 2 moving along with the conveyor belt 403 and being clamped and limited by the positioning clamping plates 501, it can be accurately moved to the bottom of the set filling box 302. By starting the filling box 302 supported and fixed by the support frame 301 and equipped with an automatic discharging system, the tea contained therein can be discharged automatically and filled into the tea packaging box 2 below, achieving the effect of automatic filling and packaging of tea;

[0032] It should be noted that the automatic discharging system installed in the filling box 302 set in this application adopts the prior art, and specifically, reference can be made to existing filling equipment.

[0033] Furthermore, the limiting mechanism 7 includes two limiting baffles 701 and a sliding assistance component 8. One ends of the two limiting baffles 701 are respectively fixedly connected to one ends of the two positioning clamping plates 501 at an inclined angle of 45 degrees, and the sliding assistance component 8 is installed on the side walls of the two limiting baffles 701;

[0034] The sliding assistance component 8 includes a plurality of mounting grooves 801 and a plurality of sliding assistance rollers 802. The plurality of mounting grooves 801 are symmetrically opened on the side walls of the two limiting baffles 701 respectively, and both ends of the plurality of sliding assistance rollers 802 are respectively rotatably connected to both ends of the plurality of mounting grooves 801;

[0035] On the basis of the above embodiments, while the tea packaging box 2 is moved and conveyed by the conveyor belt 403, when the conveying distance is long or the placement position is improper and the tea packaging box 2 is offset, at this time, after the tea packaging box 2 moves and contacts the limit baffle 701 installed at an inclined angle of 45 degrees, the tea packaging box 2 can be forced to move closer to the middle of the two positioning clamping plates 501 along the inclined angle of the limit baffle 701. At the same time, by moving along the limit baffle 701, the tea packaging box 2 can contact the arranged auxiliary sliding roller 802, so that the arranged auxiliary sliding roller 802 is forced to rotate in the opened installation groove 801. By the rotation of the auxiliary sliding roller 802, the frictional force received by the tea packaging box 2 is changed from sliding friction to rolling friction, thereby reducing the frictional force. In this way, it is convenient to limit and assist the sliding movement guidance of the tea packaging box 2, so that the offset tea packaging box 2 can move back normally, thus facilitating the normal filling and packaging effect.

[0036] The implementation principle of an automatic tea packaging machine according to an embodiment of the present application is as follows: When in use, first, according to the size of the tea packaging box 2, two electric push rods 603 controlled by the same control system are activated to extend and retract, thereby driving the two telescopic rods 604 connected thereto to be stressed and slide telescopically inside one end of the two telescopic cylinders 602 supported and fixed by the two fixed blocks 601. By the telescopic sliding movement of the telescopic rods 604, the two positioning clamping plates 501 connected thereto are stressed to move, open or close on the top of the conveyor belt 403. By the movement, opening or closing of the two positioning clamping plates 501, the size of the clamped and positioned object is adjusted and changed, thereby effectively facilitating the adjustment and change of the size of the clamped and positioned object according to the usage requirements, so as to facilitate the clamping, limiting and positioning of tea packaging boxes 2 of different sizes, without the need to replace different devices for limiting and positioning, effectively improving the usage convenience. At this time, the tea packaging box 2 is placed on the conveyor belt 403, and then the motor 402 is activated to provide a driving force to drive one of the pulleys 401 connected thereto to rotate under stress. By the rotation of one of the pulleys 401 and the cooperative rotation of the other pulley 401, the conveyor belt 403 is driven to rotate and move. By the rotation and movement of the conveyor belt 403, the tea packaging box 2 placed thereon is driven to move and convey. At this time, after the tea packaging box 2 moves along with the conveyor belt 403 and is clamped and limited by the positioning clamping plates 501, it can be accurately moved to the bottom of the filling hopper 302. By starting the filling hopper 302 supported and fixed by the support frame 301 and equipped with an automatic discharging system, the tea contained therein can be discharged and automatically filled into the tea packaging box 2 below, achieving the effect of automatic filling and packaging of tea. Secondly, while the conveyor belt 403 conveys the tea packaging box 2, when the conveying distance is long or the placement position is improper and the tea packaging box 2 is offset, at this time, after the tea packaging box 2 moves and contacts the limiting baffle 701 installed at an angle of 45 degrees, the tea packaging box 2 can be stressed to move towards the middle of the two positioning clamping plates 501 along the inclination angle of the limiting baffle 701. At the same time, by the movement of the tea packaging box 2 along the limiting baffle 701, it can contact the auxiliary sliding roller 802, causing the auxiliary sliding roller 802 to rotate under stress in the installed groove 801 opened. By the rotation of the auxiliary sliding roller 802, the friction force received by the tea packaging box 2 is changed from sliding friction to rolling friction, thereby reducing the friction force. In this way, it can effectively facilitate the limiting, auxiliary sliding and movement guidance of the tea packaging box 2, enabling the offset tea packaging box 2 to move back normally, so as to facilitate the normal filling and packaging.

[0037] The above are all the preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore: All equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
