Description

Technical Field

[0001] This utility model relates to the field of automatic tape-sealing machine technology, specifically to a heat-sealing device for an automatic tape-sealing machine with a biting mechanism. Background Technology

[0002] Currently, the stacking, packaging, and shipping of sheet materials requires the use of automatic strapping machines. These machines consist of a vertical frame through which the sheet materials pass, a plastic-coated steel strap inside the frame, and mechanisms for feeding, pulling, heat sealing, and cutting the strap. During strapping, the sheet materials are conveyed through the vertical frame by the conveyor belt, and then the plastic-coated steel strap of the frame straps the materials.

[0003] During the heat sealing process of the tape, because the tape is still under tension, excessive tension can cause it to be overstretched, reducing the bonding area, decreasing adhesion, or even preventing bonding altogether, thus increasing the risk of the tape breaking. Furthermore, excessive tension can also cause the tape to spring back during the cutting process after bonding. A strong springback could cause the tape to break into fragments and may also lead to deformation, wear, or breakage of critical mechanical components (such as guide wheels and cutters). Utility Model Content

Detailed Implementation

[0029] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0030] Reference Figure 1-6 The automatic tape-sealing machine heat-sealing device with a biting mechanism includes a main body 1, a heat-sealing platform 2 mounted on the main body 1, a movable heat-sealing mechanism 3 positioned in front of the heat-sealing platform 2, a tape feeding mechanism 4 positioned on both sides of the heat-sealing platform 2, and a tape biting mechanism 5. The tape biting mechanism 5 can tightly bite the tape during the tape bonding and cutting process, and then release it after the tape is cut.

[0031] Specifically, the top of the main body 1 of the movement is movably equipped with an upper plate tooth 6 that can approach or move away from the heat sealing table 2. When the upper plate tooth 6 approaches the heat sealing table 2, the end of the upper plate tooth 6 will be located above the heat sealing table 2. The tape biting mechanism 5 includes a lifting tape biting tooth 51 adapted to the upper plate tooth 6. The lifting tape biting tooth 51 is connected to a lifting drive source 52 that drives the lifting tape biting tooth 51 to mesh with the upper plate tooth 6. When the tape is unwound through the plastic steel tape loop and wraps around the inside of the vertical frame to reach the heat sealing table 2, the upper plate tooth 6 moves towards the heat sealing table 2, and the lifting drive source 52 drives the lifting tape biting tooth 51 to mesh with the upper plate tooth 6, tightly biting the tape.

[0032] To achieve the interlocking effect, the upper plate tooth 6 has a wavy upper tooth 61 protruding downward on one side of its bottom near the heat sealing platform 2, and the top of the lifting bite tooth 51 is provided with an "M"-shaped lower tooth 511 adapted to the wavy upper tooth 61. Figure 2 As shown, when the lifting and biting teeth 51 rise and engage with the upper plate teeth 6, the "M"-shaped lower teeth 511 engage with the wavy upper teeth 61. This design can tightly grip the belt and prevent the belt from being pulled off.

[0033] Reference Figure 3 To achieve the lifting and lowering of the lifting and biting toothed component 51, the lifting drive source 52 includes a mounting base 521 installed on the main body 1 of the movement, a lever 522 movably hinged to the mounting base 521, and a lifting cylinder 523 for driving the lifting and biting toothed component 51. One end of the lever 522 is connected to the lifting and biting toothed component 51, and the other end is hinged to the lifting cylinder 523. The lifting cylinder 523 is connected to one end of the lever 522 via a push rod. To install the lever 522, a lever connector 524 is provided on the top of the mounting base 521, and a lever shaft 525 is provided on the free end of the lever connector 524. The middle part of the lever 522 is movably hinged to the lever shaft 525. The design utilizes the lever principle. When the lifting cylinder 523 drives the push rod to rise, the lifting and biting toothed component 51 descends under the action of the lever 522; when the lifting cylinder 523 pulls the push rod to descend, the lifting and biting toothed component 51 rises under the action of the lever 522.

[0034] Furthermore, the feeding mechanism 4 includes an upper feeding plate 41 and a lower feeding plate 42 located below the upper feeding plate 41. A feeding groove for the tape to pass through is formed between the upper feeding plate 41 and the lower feeding plate 42, and the tape outlet of the feeding groove faces the heat sealing table 2. A cutter 44 for cutting the tape is provided at the tape outlet of the feeding groove. The feeding mechanism 4 also includes a tape feeding pressure roller assembly 43. A tape feeding telescopic groove 7 that can move relative to the upper plate teeth 6 is provided below the upper plate teeth 6. After the plastic steel tape ring is unwound, the tape passes through the tape pulling mechanism of the tape winding machine, the feeding groove of the feeding mechanism 4, the tape feeding telescopic groove 7, and the tape passing groove (not shown in the figure) in sequence before it can wrap around the inside of the vertical frame once.

[0035] Reference Figure 4 To enable the movement of the upper plate tooth 6 and the tape feeding telescopic groove 7, the upper plate tooth 6 and the tape feeding telescopic groove 7 are brought closer to or further away from the heat sealing table 2 via a cam swing arm mechanism 8. The cam swing arm mechanism 8 includes a telescopic groove swing arm 82 and an upper plate tooth swing arm 83 hinged to a swing rod shaft 81, and an upper plate tooth cam 85 sleeved on the tape cutting main shaft 84. The upper plate tooth cam 85 is movably connected to the upper plate tooth swing arm 83. The other end of the telescopic groove swing arm 82 is connected to the tape feeding telescopic groove 7, and the other end of the upper plate tooth swing arm 83 is connected to the upper plate tooth 6. The upper plate tooth 6 has stepped flanges 62 protruding outwards at both ends. The main body 1 of the movement is provided with an upper plate tooth groove 11 at the connection point with the upper plate tooth 6, which is slidably connected to the stepped flanges 62. When the upper plate tooth swing arm 83 swings, the upper plate tooth 6 can slide back and forth relative to the upper plate tooth groove 11. The bottom of the upper plate tooth 6 is provided with a telescopic groove mounting base 63 that engages with the tape feeding telescopic groove 7, and the tape feeding telescopic groove 7 is slidably connected to the telescopic groove mounting base 63. When the telescopic groove swing arm 82 swings, the tape feeding telescopic groove 7 can slide back and forth relative to the upper plate tooth 6.

[0036] To achieve heat sealing without affecting the tape threading, the movable heat sealing mechanism 3 includes a heating element 31, a heating element slide 32 located below the heating element 31, and a heating element swing arm 33 that drives the heating element slide 32 to move the heating element 31 closer to or away from the heat sealing table 2. The other end of the heating element swing arm 33 is rotatably connected to a heating element swing rod shaft 12 mounted on the main body 1 of the movement, and the heating element swing arm 33 is movably connected to a heating element cam 34 sleeved on the tape cutting main shaft 84. A heating element mounting seat 35 is provided on the main body 1 of the movement, and the heating element slide 32 is slidably connected to the heating element mounting seat 35. When the tape biting mechanism 5 bites the tape, the heating element swing arm 33 drives the heating element 31 to move towards the heat sealing table 2 to adhere the tape.

[0037] Working principle: Before the plastic steel tape ring is unwound, the telescopic groove arm 82 swings towards the heat sealing table 2, driving the tape feeding telescopic groove 7 to move towards the heat sealing table 2 until the groove opening of the tape feeding telescopic groove 7 aligns with the tape exit groove opening of the tape feeding mechanism 4. After the plastic steel tape ring is unwound, the tape passes through the tape pulling mechanism of the tape beater, the tape feeding groove of the tape feeding mechanism 4, the tape feeding telescopic groove 7, and the tape passing groove (not shown in the figure) in sequence, winding around once inside the vertical frame; when the free end of the tape reaches the position of the heat sealing table 2, the telescopic groove arm 82 resets, driving the tape feeding telescopic groove 7 to move away from the heat sealing table 2 and exit; at this time, the upper plate tooth arm 83 swings towards the heat sealing table 2, driving the upper plate tooth 6 to move towards the heat sealing table 2. At the same time, the lifting cylinder 523 pulls the push rod down, and the lifting biting tooth 51 rises under the action of the lever 522 and engages with the wave-shaped upper tooth 61 of the upper plate tooth 6 to bite the tape. Then, the heating element swing arm 33 drives the heating element 31 to move towards the heat sealing table 2 to adhere the tape. After the tape is heat-sealed and cut, the upper plate tooth swing arm 83 resets, driving the upper plate tooth 6 to move away from the heat sealing table 2 and exit; at the same time, the lifting cylinder 523 drives the push rod to rise, and the lifting biting tooth 51 descends and resets under the action of the lever 522.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
