[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described below.

[0037] Please refer to this carefully. Figure 1-4 and Figure 7 The present invention discloses a stacking box tightening device, including a top box mechanism 90 and a box feeding mechanism 110, a limiting member 60, and a tightening mechanism 70 arranged sequentially from bottom to top. The tightening mechanism 70 includes a first pushing belt 1 and a second pushing belt 2 arranged opposite to each other. The ends of the first pushing belt 1 and the second pushing belt 2 along the conveying direction are provided with a fixed box stop member 80.

[0038] In this embodiment, product 100 is a box-shaped material. The box-feeding mechanism 110 is used to transport the box-shaped material. The fixed box stop 80 is used to hold the box-shaped material in place and fix its position, ensuring that the box-shaped material cannot move further when it is above the top box mechanism 90. When the box-shaped material is transported to the top of the top box mechanism 90, the top box mechanism 90 pushes the box-shaped material upward, causing the box-shaped material to press upward against the limiting member 60. The limiting member 60 contracts, and the box-shaped material moves upward and between the first push belt 1 and the second push belt 2. The first push belt 1 and the second push belt 2 together tighten the box-shaped material, while the limiting member 60 recovers, and the box-shaped material is supported on the limiting member 60. When the box-feeding mechanism 110 transports the second box-shaped material, the above actions are repeated, and the later box-shaped material is stacked under the previous box-shaped material, realizing the stacking of the box-shaped materials.

[0039] According to a specific embodiment of the present invention, the box feeding mechanism 110 includes a lower first conveyor belt 3 and a lower second conveyor belt 4 arranged side by side for jointly clamping the product 100 and realizing the transfer of the product 100.

[0040] Please refer to this carefully. Figure 5-6According to a specific embodiment of the present invention, the limiting member 60 includes a first flippable wedge block unit 8 and a second flippable wedge block unit 5 arranged side by side and spaced apart. The first flippable wedge block unit 8 includes: a first rotating seat 81, a first wedge strip 82 rotatably connected to the first rotating seat 81, and a first return spring 83 connected to the first wedge strip 82. The second flippable wedge block unit 5 includes: a second rotating seat 51, a second wedge strip 52 rotatably connected to the second rotating seat 51, and a second return spring 53 connected to the second wedge strip 52.

[0041] In this embodiment, when the product 100 moves upward under the force of the top box mechanism 90, the upper ends of the product 100 press against the wedge surfaces of the first wedge strip 82 and the second wedge strip 52, causing the first wedge strip 82 and the second wedge strip 52 to rotate and open under force, and respectively compress the first return spring 83 and the second return spring 53. The product 100 passes through the channel between the first wedge strip 82 and the second wedge strip 52 and continues upward. When the product 100 has completely passed through, the first wedge strip 82 and the second wedge strip 52 lose the pressing force of the product 100. Under the reset action of the first return spring 83 and the second return spring 53, the first wedge strip 82 and the second wedge strip 52 rotate in the opposite direction and return to the original position. When it is necessary to continue stacking products 100, the next product 100 is moved upward by the force of the top box mechanism 90, and the above action is repeated. The difference is that since there is already a product 100 on the upper part of the first wedge strip 82 and the second wedge strip 52, when the next product 100 moves on the first wedge strip 82 and the second wedge strip 52, the previous product 100 is naturally stacked on the next product 100, completing the stacking of two products 100, and then entering the next process, the stacked products 100 are treated as a whole, and a layer of plastic film is wrapped around the outside of the whole to form a sealed protection to meet production requirements.

[0042] According to a specific embodiment of the present invention, the first reversible wedge block unit 8 and the second reversible wedge block unit 5 are symmetrical to each other.

[0043] In this embodiment, two sets of symmetrical units are used for support, which improves the stability of the product 100 support. Furthermore, the symmetrical structure facilitates parts standardization and reduces the manufacturing cost of the device.

[0044] According to a specific embodiment of the present invention, the limiting member 60 includes a supporting state. When the limiting member 60 is in the supporting state, the side of the first wedge 82 near the second wedge 52 is a first inclined surface 821, and the upper surface of the first wedge 82 is a first plane 822; the side of the second wedge 52 near the first wedge 82 is a second inclined surface 521, and the upper surface of the second wedge 52 is a second plane 522.

[0045] In this embodiment, the limiting member 60 is in a supported state by the first return spring 83 and the second return spring 53. The limiting member 60 also includes a flipped state, which is achieved by pressing the first inclined surface 821 and the second inclined surface 521 upward from both ends of the upper part of the product 100.

[0046] According to a specific embodiment of the present invention, when the limiting member 60 is in a supporting state, the included angle between the first inclined surface 821 and the second inclined surface 521 is A, where A = 60° to 80°.

[0047] According to a specific embodiment of the present invention, both the first push belt 1 and the lower first conveyor belt 3 are driven by the first belt transmission power, wherein: the first belt transmission power includes: a first motor 6, a first driving wheel connected to the first motor 6, and a first driven wheel spaced apart from the first driving wheel, and the first push belt 1 and the lower first conveyor belt 3 are respectively arranged around the first driving wheel and the first driven wheel.

[0048] According to a specific embodiment of the present invention, both the second push belt 2 and the lower second conveyor belt 4 are driven by the second belt transmission power, wherein: the second belt transmission power includes: a second motor 7, a second driving wheel connected to the second motor 7, and a second driven wheel spaced apart from the second driving wheel, and the second push belt 2 and the lower second conveyor belt 4 are respectively arranged around the second driving wheel and the second driven wheel.

[0049] According to a specific embodiment of the present invention, the first push belt 1, the lower first conveyor belt 3 and the first belt transmission power drive together constitute the first conveyor assembly 20, and the second push belt 2, the lower second conveyor belt 4 and the second belt transmission power drive together constitute the second conveyor assembly 30. The stacking box tightening device also includes a bottom support component 40 for supporting the first conveyor assembly 20 and the second conveyor assembly 30.

[0050] The present invention also discloses a wrapping machine, including the stacking and tightening device as described above, an adsorption film feeding mechanism 50 above the tightening mechanism 70, and a box feeding and wrapping mechanism 10 above the adsorption film feeding mechanism 50.

[0051] In this embodiment, the film is delivered to the laminating station by the adsorption film feeding mechanism 50 and placed on the stacked boxed materials. The box-wrapping mechanism 10 is used to transport the boxed materials to the laminating station and wrap them. Both the adsorption film feeding mechanism 50 and the box-wrapping mechanism 10 are existing technologies in wrapping machines, and their specific structures will not be described further.
