DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] like Figure 1 As shown, Figure 1 Shown is an overall schematic diagram of a heat sealing device in an embodiment.

[0024] The device comprises a bracket 11, the bracket 11 comprises a horizontally arranged horizontal plate 12, a movable plate 13 is arranged at the bottom of the horizontal plate 12, a lifting assembly is arranged at the top of the movable plate 13, and a heat sealing assembly is arranged at the bottom of the movable plate 13;

[0025] The heat-sealing assembly heat-seals the tea packaging bag, and the lifting assembly drives the movable plate 13 and the heat-sealing assembly to move up and down to adjust the height, which is suitable for tea packaging bags of different heights.

[0026] A guide rod 2 14 penetrating the movable plate 13 is also vertically symmetrically arranged between the horizontal plate 12 and the bottom plate of the bracket 11. The guide rod 2 14 plays a guiding role in adjusting the height of the movable plate 13, so that the movable plate 13 can be stably lifted and lowered.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, Figure 1 Shown is an overall schematic diagram of the heat sealing device in the embodiment, Figure 2 It shows Figure 1 A schematic diagram of the structure enlargement in the middle; Figure 3 Shown is a schematic diagram of an active block in an embodiment; Figure 4 Shown is a schematic diagram of the cam installation in the embodiment.

[0028] The heat sealing assembly includes a guide rod 21, a fixed block 22 and a movable block 23, wherein the guide rod 21 is fixedly arranged on the movable plate 13 and sequentially passes through the fixed block 22 and the movable block 23, wherein the fixed block 22 is fixedly connected to the guide rod 21, and the movable block 23 is slidably connected to the guide rod 21;

[0029] The fixed block 22 and the movable block 23 are both provided with mounting grooves at their ends close to each other, a melting plate 24 is fixedly installed in the mounting groove of the fixed block 22, and a melting plate 25 is fixedly installed in the mounting groove of the movable block 23, wherein the melting plate 1 24 is recessed into the mounting groove of the fixed block 22, and the melting plate 25 protrudes from the mounting groove of the movable block 23, and the protruding height of the melting plate 25 matches the recessed height of the melting plate 1 24.

[0030] The tea packaging bag is sealed by bringing the movable block 23 close to the fixed block 22 and fitting the melting plate 1 24 with the melting plate 2 25. The concave melting plate 1 24 and the convex melting plate 2 25 are arranged to squeeze each other, so that the sealing can be tighter.

[0031] A spring 26 is sleeved on the outer circumference of the guide rod 21 located between the fixed block 22 and the movable block 23, and two ends of the spring 26 are fixedly connected to the fixed block 22 and the movable block 23 respectively.

[0032] The movable plate 13 further includes a driving member, which is arranged on a side of the movable block 23 away from the fixed block 22. The driving member includes a mounting plate 27 symmetrically arranged at the bottom end of the movable plate 13. A connecting rod 28 is rotatably arranged between the mounting plates 27. A cam 29 is fixedly sleeved on the connecting rod 28. A turntable 30 is rotatably arranged on one end of one of the mounting plates 27 away from the cam 29. The end of the turntable 30 close to the connecting rod 28 is connected to the connecting rod 28. A handle 31 is arranged on the other end of the turntable 30.

[0033] By manually rotating the handle 31, the rotating disk 30, the connecting rod 28 and the cam 29 are driven to rotate, so as to intermittently push the movable block 23, so that the movable block 23 is close to the fixed block 22 and heat-seals the tea packaging bag therebetween. While the movable block 23 and the fixed block 22 heat-seal the tea packaging bag, the spring 26 is squeezed and then quickly recovers, so as to avoid the contact time of the melting plate 1 24 and the melting plate 2 25 being too long, resulting in overheating.

[0034] like Figure 1 As shown, Figure 1 Shown is an overall schematic diagram of a heat sealing device in an embodiment.

[0035] The lifting assembly includes a driving gear 41 arranged at the top of the horizontal plate 12, and driven gears 42 are meshed on both sides of the driving gear 41. The driven gear 42 is fixedly connected with a threaded sleeve 43 along the vertical direction, and the internal thread of the threaded sleeve 43 is connected with a threaded rod 44; the bottom end of the threaded rod 44 is fixedly connected to the movable plate 13.

[0036] A motor is also provided at the bottom end of the horizontal plate 12 corresponding to the position of the driving gear 41 , and the output shaft of the motor is connected to the driving gear 41 to drive the driving gear 41 to rotate.

[0037] The motor is turned on to drive the driving gear 41 to rotate, and the driving gear 41 drives the driven gear 42 to rotate, thereby driving the threaded sleeve 43 connected to the driven gear 42 to rotate, so that the threaded rod 44 moves up and down inside the threaded sleeve 43, and finally the height of the movable plate 13 is adjusted.

[0038] A limiting member is provided at the inner bottom end of the threaded sleeve 43 to prevent the threaded rod 44 from being separated from the threaded sleeve 43 .

[0039] Working principle: When heat-sealing tea packaging bags through this device, first adjust the height of the movable plate 13 according to the height of the packaging bag to be sealed, then place the tea packaging bag on the bottom plate of the bracket 11, and the open end of the packaging bag is located between the fixed block 22 and the movable block 23. By manually turning the handle 31, the turntable 30, the connecting rod 28, and the cam 29 are driven to rotate until the long axis end of the cam 29 pushes the movable block 23, so that the movable block 23 is close to the fixed block 22, and the melting plate 1 24 and the melting plate 2 25 are in contact to achieve sealing. When the melting plate 1 24 and the melting plate 2 25 are in contact, the spring 26 is squeezed and then quickly restored to avoid the melting plate 1 24 and the melting plate 2 25 from contacting for too long and causing overheating.

[0040] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
