[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Such as Figures 1-6As shown, the utility model discloses a core of a tape sealing machine, which includes a left core side plate 1, a right core side plate 2, a tape pressing wheel mechanism 3, a tape fixing mechanism 4 and a tape cutting mechanism 5 located on the core side plates. The left core side plate 1 and the right core side plate 2 are respectively located on the left and right sides of the tape pressing wheel mechanism 3, the tape fixing mechanism 4 and the tape cutting mechanism 5. Usually in the physical object, there is a conveyor belt arranged on the right side of the left core side plate 1 and the left side of the right core side plate 2. The belt is driven by a motor to realize the stable and continuous movement of the box placed on the conveyor belt from front to back (this is the prior art and not shown in the figure and will not be specifically described. For details, reference can be made to Chinese Patent No. CN201920808812.7, an automatic tape sealing machine). It also includes a brush 6 and a rear mounting seat 61 fixedly installed at the bottom of the brush 6 by welding or other means. The tape pressing wheel structure includes a front movable frame 31 and a front tape pressing wheel 311 fixedly installed on the front movable frame 31 by bolts or other means, a rear movable frame 32 and a rear tape pressing wheel 321 and a connecting rod 33 fixedly installed on the rear movable frame 32 by bolts or other means. The front movable frame 31 is rotatably installed on the front side of the connecting rod 33, and the rear movable frame 32 is rotatably installed on the rear side of the connecting rod 33. The tape cutting mechanism 5 is located between the front movable frame 31 and the rear movable frame 32. The brush 6 is located on the rear side of the rear movable frame 32. The left and right sides of the rear mounting seat 61 are detachably connected to the left core side plate 1 and the right core side plate 2 by bolts or other means. The tape cutting mechanism 5 is movably installed between the left core side plate 1 and the right core side plate 2. After the tape is placed on the tape fixing mechanism 4, one end of the tape is located between the left core side plate 1 and the right core side plate 2. The box to be sealed is placed on the conveyor belt through the conveyor belt and moves from front to back. During its movement, the rear end face of the box can push the front tape pressing wheel 311 downward, driving the front movable frame 31 to rotate downward. Also, because both the front movable frame 31 and the rear movable frame 32 are rotatably installed on the connecting rod 33, at this time, as the front movable frame 31 rotates downward, the left side of the connecting rod 33 moves forward and upward. At this time, the box moving backward can push the tape cutting mechanism 5 downward. At the same time, as the left movable frame moves downward, the rear side of the connecting rod 33 will move downward, driving the rear movable frame 32 and the rear tape pressing wheel 321 to rotate downward to facilitate the box to move backward. And during the backward movement of the box, the tape can stick to the bottom of the box and be pulled out continuously as the box moves backward, sticking to the bottom of the box continuously to realize the sealing operation of the bottom of the box. When the bottom of the box is separated from the tape cutting mechanism 5, the tape cutting structure resets to cut the tape on the box. And because the bottom of the box passes over the brush 6 during the movement of the box from front to back, the brush 6 can wipe the tape attached to the bottom of the box, so that the tape can be stably attached to the box.

[0031] Among them, it also includes a left bolt 7 and a right bolt 8. The left bolt 7 is inserted through the left movement mechanism side plate 1 and is in threaded cooperation with the left side of the rear mounting seat 61. The right bolt 8 is inserted through the right movement mechanism side plate 2 and is in threaded cooperation with the right side of the rear mounting seat 61. Since the left side of the rear mounting seat 61 at the bottom of the brush 6 is connected to the left movement mechanism side plate 1 through the left bolt 7, and the right side of the rear mounting seat 61 is connected to the right movement mechanism side plate 2 through the right bolt 8, the rear mounting seat 61 can be stably located between the left movement mechanism side plate 1 and the right movement mechanism side plate 2 in the use state. During the process of the box moving from front to back and its bottom contacting the brush 6, the brush 6 can be stably located between the left movement mechanism side plate 1 and the right movement mechanism side plate 2, and then can stably wipe the tape and the box located at the bottom of the box, so that the tape can fully fit with the bottom of the box and be stably located at the bottom of the tape. When it is necessary to clean the brush 6, by removing the left bolt 7 and the right bolt 8 respectively, the rear mounting seat 61 can be taken out from between the left movement mechanism side plate 1 and the right movement mechanism side plate 2 to realize the maintenance of the brush 6.

[0032] Among them, the tape cutting mechanism 5 includes a blade 51, a connecting seat 52 and a tension spring 53. A fixing plate 511 is fixedly installed on the front side of the blade 51. The rear side of the connecting seat 52 is detachably connected to the fixing plate 511 by bolts, buckles and other means. The front side of the connecting seat 52 is rotatably installed on the left movement mechanism side plate 1. The front side of the tension spring 53 is sleeved on the connecting seat 52, and the rear side of the tension spring 53 is sleeved on the left movement mechanism side plate 1. A contact part 521 is arranged on the rear side of the connecting seat 52, and the height of the contact part 521 is higher than that of the blade 51. Due to the existence of the contact part 521 on the connecting seat 52, when the box moves from front to back and presses down the front tape pressing wheel 311 and the front movable frame 31, it will push the contact part 521, so that the rear side of the connecting seat 52 rotates downward. Also, because the rear side of the connecting seat 52 is connected to the fixing plate 511, the fixing plate 511 is located in front of the blade 51 and is fixed to the blade 51. Therefore, as the connecting seat 52 rotates downward, it can drive the fixing plate 511 and the blade 51 to move downward, so that the box moves smoothly backward and does not contact the blade 51. When the end of the box leaves the contact part 521 of the connecting seat 52, at this time, under the action of the elastic force of the tension spring 53, the connecting seat 52 will reset and rotate upward, thereby driving the fixing plate 511 and the blade 51 to rotate upward. At this time, the upward blade 51 will contact the tape at the end of the box to complete the cutting action of the tape.

[0033] In addition, the tape cutting mechanism 5 further includes a flip cover 54 and a torsion spring 55 located at the rear side of the blade 51. The flip cover 54 is provided with a protective plate 541 protruding upward. The protective plate 541 is located above the blade 51. The protective plate 541 is provided with a pushing portion 5411 protruding upward. The height of the pushing portion 5411 is higher than that of the contact portion 521. A fixing seat 5111 is integrally formed at the bottom of the fixing plate 511. A fitting post 542 is provided at the bottom of the flip cover 54. The torsion spring 55 is sleeved on the circumference of the fitting post 542 and one end thereof is fixed to the fixing plate 511 and the other end is fixed to the flip cover 54. 1. Since the flip cover 54 is located at the rear side of the blade 51 and the protective plate 541 of the flip cover 54 is located above the blade 51, the operator will not directly contact the blade 51 without external force, thus improving the safety of the device. 2. Since the height of the pushing portion 5411 is higher than that of the contact portion 521, when the box passes through the tape cutting mechanism 5 from front to back, in addition to applying a downward pressure to the contact portion 521 to drive the connecting seat 52, the fixing plate 511 and the blade 51 to rotate downward, the rear side of the box that continues to move backward will abut against the pushing portion 5411 of the flip cover 54. And because the torsion spring 55 is sleeved on the fitting post 542 at the bottom of the flip cover 54, and one end of the torsion spring 55 is connected to the fixing plate 511 and the other end is connected to the flip cover 54, when the box moves backward and pushes the pushing portion 5411 of the flip cover 54, the flip cover 54 will rotate backward. When the box drives the flip cover 54 to rotate backward, the blade 51 loses the shielding of the flip cover 54, and when the connecting seat 52 is reset under the elastic force of the tension spring 53, it drives the blade 51 to move upward to cut the tape at the end of the box. When the box completely leaves the tape cutting mechanism 5, at this time, the torsion spring 55 loses the external force and drives the flip cover 54 to reset to shield the blade 51, so that the blade 51 will not be contacted without external force.

[0034] It further includes a plurality of connecting bolts (not shown in the figure). The fixing plate 511 is arranged in an L shape and is fixedly connected to the connecting seat 52 on the right side. Each connecting bolt is inserted into the left side of the fixing plate 511 and is in threaded cooperation with the left movement mechanism side plate 1. Since each connecting bolt is inserted into the left side of the fixing plate 511 and is in threaded cooperation with the left movement mechanism side plate 1, if the blade 51 becomes dull or is attached with impurities and needs to be cleaned during long-term use, at this time, the fixing plate 511 and the connecting seat 52 can be separated by removing each connecting bolt, and then the fixing plate 511 and the blade 51 can be removed to replace or clean the blade 51.

[0035] Among them, it further includes a front mounting seat 9, and the front mounting seat 9 is located on the left side of the front movable frame 31. Since the front mounting seat 9 is located on the left side of the front movable frame 31, and during the process of the box moving from front to back, the box will push the front tape pressing wheel 311 downward, thereby driving the front movable frame 31 to rotate downward and to the right. The existence of the front mounting seat 9 can prevent the front movable frame 31 from rotating forward, that is, counterclockwise, during accidental touch and movement of the movement, thereby limiting the rotation trajectory of the front tape pressing wheel 311. Similarly, due to the existence of the rear mounting seat 61, the rear movable frame 32 can rotate counterclockwise and cannot rotate clockwise, thereby realizing the limitation of the rotation trajectories of the rear movable frame 32 and the rear tape pressing wheel 321.

[0036] Among them, the tape fixing mechanism 4 includes a support rod 41. The support rod 41 is fixedly connected to the right movement side plate 2 by means of bolts or the like. The bottom of the support rod 41 is fixedly installed with a tape fixing frame 42 by means of bolts or the like. A tape guiding frame 43 is arranged above the tape fixing frame 42 on the right movement side plate 2. The tape is sleeved on the tape fixing frame 42, and the head passes around the front side of the tape guiding frame 43 and then moves towards the cutter, and the adhesive surface of the tape faces upward. Thus, during the process of the box moving from front to back, the head of the tape can adhere to the rearmost side of the bottom of the box, and then, with the movement of the box, the complete pasting of the bottom of the box is realized. The tape guiding frame 43 can play a role in guiding and limiting the placement path of the tape on the movement.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
