Technical Field

[0001] The utility model relates to the technical field of tea filter paper manufacturing, in particular to a sealing device for tea filter paper manufacturing which is easy to operate. Background Art

[0002] Tea filter paper is a kind of paper made of cellulose with good softness, strength and permeability. It is usually used to filter tea residues to make the tea soup clearer.

[0003] The existing tea filter paper sealing device is prone to incomplete fitting of the filter papers when sealing the filter papers filled with tea leaves, resulting in gaps in the seal and leakage of tea leaves. Secondly, most tea filter paper sealing devices use hot pressing to seal the filter papers. When the staff fits the filter paper and places it at the seal, it is easy to touch the heating plate, which may cause skin burns to the staff. Moreover, before placing the filter paper at the seal, a staff member is required to keep the filter paper filled with tea leaves in a well-fitted state, which is not only time-consuming and labor-intensive, but also affects the sealing efficiency of the tea filter paper.

[0004] Therefore, in order to solve the above problems, a sealing device for manufacturing tea filter paper which is easy to operate is proposed. Utility Model Content

[0013] Furthermore, the heat sealing assembly includes a reciprocating motor mounted on the lower surface of the top plate of the carrier frame, and the output end of the reciprocating motor is vertically arranged downward and connected to a worm.

[0014] Furthermore, both sides of the worm along the direction of the two side plates of the support frame are meshedly connected with worm wheels, and a limit rod is installed through the centers of the two worm wheels.

[0025] See also Figure 1-3In this embodiment, a convenient sealing device for manufacturing tea filter paper includes a frame 1, a clamping assembly 2 and a heat sealing assembly 3, and is characterized in that: a driving wheel 12 and a driven wheel 13 are rotatably connected between the two side plates of the frame 1; bearings are filled and assembled on the inner walls of the two side plates of the frame 1, and the driving wheel 12 and the driven wheel 13 are rotatably connected to the two side plates of the frame 1 through the bearings;

[0026] A stepper motor 11 is installed on the outer wall of a side plate of one side of the frame 1, and the output end of the stepper motor 11 passes through the side plate of one side of the frame 1 and is connected to a driving wheel 12; a track 14 is rotatably connected between the driving wheel 12 and the driven wheel 13; four groups of clamping components 2 are installed at intervals on the outer wall of the track 14; a bearing frame 15 is installed on the upper surface of the two side plates of the frame 1, and a heat sealing component 3 is installed on the lower surface of the top plate of the bearing frame 15.

[0027] In this embodiment, through the cooperation between the stepper motor 11, the driving wheel 12 and the driven wheel 13, the track 14 can drive the tea filter paper clamped and bonded by the clamping component 2 to pass through the heat sealing component 3 for sealing, thereby avoiding the need for staff to manually keep the tea filter paper in a well-bonded state, and avoiding the need for staff to be burned when placing the well-bonded tea filter paper at the sealing point.

[0028] The clamping assembly 2 in this embodiment includes two mounting seats 21 installed horizontally on the outer wall of the track 14, and connecting columns 22 are connected between the two side plates of the two mounting seats 21. The two mounting seats 21 are respectively rotatably connected with clamping plates 23. The two clamping plates 23 are arranged in opposite directions and have positioning holes 24 running through the bottom. The clamping plates 23 are sleeved on the outer wall of the connecting columns 22 through the positioning holes 24 and are rotatably connected to the mounting seats 21. The lower ends of the opposite sides of the two clamping plates 23 are equipped with springs 25, and the other ends of the two springs 25 are installed on the outer wall of the track 14.

[0029] In this embodiment, when the staff uses the device, they first pull the two clamps 23 away from each other. At this time, the spring 25 is stretched, and then the filter paper containing tea leaves is placed between the two clamps 23. The clamps 23 are loosened, and the spring 25 retracts to drive the two clamps 23 to come close to each other, so that the middle and upper ends of the filter paper can be fitted under the support of the clamps 23, and the clamped filter paper moves toward the direction of the heat sealing component 3 under the movement of the crawler 14.

[0030] The heat sealing assembly 3 in this embodiment includes a reciprocating motor 31 installed on the lower surface of the top plate of the carrier frame 15, and the output end of the reciprocating motor 31 is vertically arranged downward and connected to a worm 32; the worm 32 is meshed and connected to worm wheels 33 on both sides along the two side plates of the carrier frame 15, and a limit rod 34 is installed through the center of the two worm wheels 33.

[0031] Support seats 36 are installed on the inner walls of the two side plates of the carrier frame 15. Grooves are opened on the inner walls of the two side plates of the support seats 36 near the end of the worm 32. Both ends of the limiting rod 34 are sleeved in the grooves, and the worm wheel 33 is rotatably connected to the support seat 36 through the limiting rod 34.

[0032] The two worm gears 33 are respectively meshed with oppositely arranged oblique racks 35 along the outer wall of the side adjacent to the side plate of the carrier 15, and a limit block 37 is installed between the two side plates of the support seat 36. The side of the limit block 37 away from the side plate of the carrier 15 is arranged with an inclined surface in a downward sliding direction and is connected to the other side of the oblique rack 35; the lower ends of the two oblique racks 35 are connected to heating plates 38, and the two heating plates 38 are arranged in opposite directions.

[0033] In this embodiment, when the clamped filter paper moves under the heat sealing assembly 3, the reciprocating motor 31 drives the worm 32 to rotate, thereby causing the worm wheel 33 to rotate, and further driving the bevel rack 35 meshing with the worm wheel 33 to slide downward, so that the heating plates 38 respectively connected to the lower ends of the two bevel racks 35 fit together, thereby performing heat pressure sealing on the upper end of the fitted filter paper. Similarly, when the sealing is completed, the reciprocating motor 31 drives the worm 32 to rotate in the opposite direction, thereby causing the two heating plates 38 to move away from each other. At this time, under the control of the stepper motor 11, the track 14 continues to move forward with the clamped and sealed filter paper, and the staff removes the sealed filter paper, thereby forming a set of assembly line-type process for sealing the filter paper.

[0034] The working principle of the above embodiment is:

[0035] In the first step, when the staff uses the device, they first pull the two clamps 23 away from each other. At this time, the spring 25 is stretched, and then the filter paper containing tea leaves is placed between the two clamps 23. The clamps 23 are loosened, and the spring 25 retracts to drive the two clamps 23 to come close to each other, so that the middle and upper ends of the filter paper can be fitted under the support of the clamps 23, and the clamped filter paper moves toward the direction of the heat sealing component 3 under the movement of the crawler 14.

[0036] In the second step, when the clamped filter paper moves under the heat sealing assembly 3, the reciprocating motor 31 drives the worm 32 to rotate, thereby causing the worm wheel 33 to rotate, and further driving the bevel rack 35 meshing with the worm wheel 33 to slide downward, thereby causing the heating plates 38 respectively connected to the lower ends of the two bevel racks 35 to fit together, thereby performing heat pressure sealing on the upper end of the fitted filter paper.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
