[0042] Reference below Figure 1 and Figure 2 The laminating mechanism according to the embodiment of the present invention is described, which is used to laminarize the base tape 110 and the covering film 120 , the base tape 110 and the covering film 120 are pasted together, and the product 130 is wrapped between the base tape 110 and the covering film 120 .

[0043] The pressing mechanism according to the embodiment of the present invention comprises a frame 200, a first pressing part 230, and a second pressing part 240. The first pressing part 230 and the second pressing part 240 are arranged side by side on the frame 200, and a gap is formed between the first pressing part 230 and the second pressing part 240, and the base tape 110 and the coating 120 slide in the gap between the first pressing part 230 and the second pressing part 240; at the same time, a receiving cavity 250 communicating with the gap is formed between the first pressing part 230 and the second pressing part 240, and the receiving cavity 250 allows the product between the base tape 110 and the coating 120 to slide through.

[0044] Specifically, when the base tape 110 and the coating 120 slide through the gap, due to the narrow size of the gap, the base tape 110 and the coating 120 are squeezed together by the first pressing part 230 and the second pressing part 240, and the product 130 is wrapped between the base tape 110 and the coating 120. Furthermore, through the design of the accommodating cavity 250, when the base tape 110 and the coating 120 are squeezed, the product 130 squeezes the base tape 110 and the coating 120 to cause a certain deformation, and the product 130 is embedded in the accommodating cavity 250 and slides through the accommodating cavity 250. In this way, the first pressing part 230 and the second pressing part 240 are prevented from crushing the product, and the coating efficiency of the product 130 is high.

[0045] In some specific embodiments of the present invention, the accommodating cavity 250 is only provided on the first pressing part 230, and the width of the accommodating cavity 250 is adapted to the width of the product 130. When the base tape 110 and the covering film 120 pass through the gap, the product 130 slides through the accommodating cavity 250 on the first pressing part 230. Similarly, the accommodating cavity 250 is only provided on the second pressing part 240. When the base tape 110 and the covering film 120 pass through the gap, the product 130 slides through the accommodating cavity 250 on the second pressing part 240 (not shown in the figure). Through the above two methods, the base tape 110 or the covering film 120 is squeezed by the product 130 to form an adapted placement cavity, so that the product is stably covered.

[0046] It is also explained that the accommodating cavity 250 is simultaneously provided on the first pressing part 230 and the second pressing part 240. When the base band 110 and the coating pass through the gap, the base band 110 and the coating 120 are deformed while the product 130 is pressed. When the base band 110 and the coating 120 slide through the gap, the product 130 slides through the accommodating cavity 250 of the first pressing part 230 and the accommodating cavity 250 on the second pressing part 240 at the same time. Through this arrangement, the deformation of the base band 110 caused by excessive pressing of the product 130 is avoided, thereby causing the base band 110 to be damaged, thereby affecting the packaging of the product 130. Moreover, through this method, when the base band 110 and the coating 120 are torn apart, it is convenient to take out the product 130.

[0047] According to the pressing mechanism of the embodiment of the present invention, the first pressing part 230 and the second pressing part 240 are provided, and the first pressing part 230 and the second pressing part 240 cooperate to press the base tape 110 and the coating film 120, and the two sides of the base tape 110 in the width direction are attached to the two sides of the coating film 120 in the width direction, and the product 130 is wrapped between the base tape 110 and the coating film 120. In addition, through the provision of the accommodating cavity 250, the product 130 is pressed against the base tape 110 to deform and is embedded in the accommodating cavity 250, so that the product 130 is prevented from being crushed, and the coating efficiency of the product 130 is high.

[0048] In some specific embodiments of the present invention, the first pressing portion 230 and the second pressing portion 240 are both cylindrical, the central axes of the first pressing portion 230 and the second pressing portion 240 are arranged in parallel, the base band 110 is attached to the lower side of the circumference of the first pressing portion 230, and the coating 120 is attached to the upper side of the circumference of the second pressing portion 240. When the base band 110 and the coating 120 slide between the first pressing part 230 and the second pressing part 240, the first pressing part 230 and the second pressing part 240 rotate, thereby reducing the friction between the base band 110 and the first pressing part 230 and the friction between the second pressing part 240 and the coating 120, thereby reducing damage to the base band 110 and the coating 120, and the base band 110 and the coating 120 are more installed to cover the product 130; and, through this arrangement, the sliding of the base band 110 and the coating 120 is smoother, thereby making the base band 110 and the coating 120 cover the product 130 more smoothly, thereby improving the efficiency of covering the product 130.

[0049] It is further explained that the first pressing part 230 and the second pressing part 240 can be plate-like bodies horizontally fixed on the frame 200, the base band 110 and the coating 120 slide between the upper side of the first pressing part 230 and the lower side of the second pressing part 240, and the accommodating cavity 250 is a U-shaped through groove horizontally opened on the upper side of the first pressing part 230; or, one of the first pressing part 230 and the second pressing part 240 is a columnar body rotatably connected to the frame 200, and the corresponding second pressing part 240 or the first pressing part 230 is a plate-like body fixed on the frame 200 (not shown in the figure).

[0050] In a further embodiment of the present invention, the first pressing part 230 includes a driving rod 233, a first side wheel 231, and a second side wheel 232. The driving rod 233 is rotatably connected to the frame 200 through a ball bearing. The first side wheel 231 and the second side wheel 232 are sleeved and fixed on the driving rod 233. Therefore, the first pressing part 230 and the second pressing part 240 are rotatably connected to the frame 200 through the driving rod 233. There is a certain distance between the first side wheel 231 and the second side wheel 232. The accommodating cavity 250 is formed between the first side wheel 231 and the second side wheel 232, and the product 130 slides through; at the same time, the second pressing part 240 is a columnar body, and the side wall of one end of the second pressing part 240 is located on the upper side of the first side wheel 231, thereby pressing downward one side of the width direction of the coating 120, and the side wall of the other end of the second pressing part 240 is located on the upper side of the second side wheel 232, thereby pressing downward the other side of the width direction of the coating 120.

[0051] In addition, the first pressing part 230 is a columnar body, the base belt 110 abuts against the side wall of the first pressing part 230, and the accommodating cavity 250 is an annular groove opened on the circumference of the first pressing part 230, so as to allow the product 130 to slide through.

[0052] For further settings, refer to Figure 2 and Figure 3 , a plurality of positioning protrusions 2311 are uniformly protruded outward on the circumference of the first pressing part 230, and the plurality of positioning protrusions 2311 are columnar bodies. A circular positioning hole 111 is opened on the base band 110 along its length direction, and the positioning hole 111 is embedded and matched with the positioning protrusion 2311. Further, in order for the positioning protrusion 2311 to be able to slide in or out of the positioning hole 111 well, the edge of the positioning protrusion 2311 away from the end of the first pressing part 230 is chamfered, and the chamfer is a chamfered right angle and a rounded angle, so that the positioning protrusion 2311 is better embedded in the positioning hole 111. Specifically, when the base band 110 is sliding, the first pressing part 230 rotates, and the positioning protrusions 2311 on the circumference of the first pressing part 230 are sequentially embedded in the positioning holes 111, and the positioning protrusion 2311 positions the base band 110 in the width direction, so that the base band 110 covers the product 130 more accurately.

[0053] In a further embodiment of the present invention, referring to Figure 2 and Figure 4 A mounting seat 241 is vertically fixed on the frame 200, and the mounting seat 241 is vertically arranged with the second pressing part 240. A sliding support 242 is vertically slidably connected to the mounting seat 241, and one end of the second pressing part 240 is vertically rotatably connected to the sliding support 242 through a rotating shaft; at the same time, an adjusting member 243 for driving the sliding support 242 to slide up and down is provided on the mounting seat 241, and the adjusting member 243 is a vertically arranged adjusting screw 2431, which is threadedly connected to the mounting seat 241, and the lower end of the adjusting screw 2431 is threadedly connected to the sliding support 242.

[0054] Specifically, the staff moves the sliding support 242 up and down, and the second pressing part 240 moves synchronously with the sliding support 242, thereby adjusting the size of the gap between the second pressing part 240 and the first pressing part 230, so as to adapt to different thicknesses of the base tape 110 and the coating 120. After the sliding support 242 is adjusted, the staff fixes the sliding support 242 to a certain position by adjusting the threaded connection between the screw rod 2431 and the sliding support 242.

[0055] In a further embodiment of the present invention, the frame 200 is composed of a frame body 210 and a flat panel 220. The frame body 210 is fixedly installed on the ground, and the flat panel 220 is horizontally installed on the top of the frame body 210. A U-shaped guide groove 221 is horizontally opened on the flat panel 220. The width of the guide groove 221 matches the width of the base belt 110 and the coating 120. Therefore, the base belt 110 and the coating 120 slide along the direction of the guide groove 221, so that the base belt 110 and the coating 120 are aligned on both sides of the width direction during the sliding process, so as to accurately cover the product 130. At the same time, an installation cavity 222 communicating with the guide groove 221 is opened on the flat panel 220. The first side wheel 510 and the second side wheel 520 are located in the installation cavity 222 just below the base belt 110, and the second pressing part 240 is located on the upper side of the guide groove 221.

[0056] According to the packaging machine of the second aspect of the present invention, Figure 2 and Figure 5 The packaging machine includes the pressing mechanism, the material receiving rack 500, and the driving member 600 of the first aspect embodiment of the present invention.

[0057] The driving member 600 is horizontally fixed on the frame 210, and the driving member 600 is a motor. The driving shaft of the driving member 600 is arranged in a pair with the driving rod 233. The end of the driving rod 233 is fixedly connected to the end of the driving shaft of the driving member 600 through a coupling. Therefore, the driving member 600 can drive the driving rod 233 to rotate through the coupling. In addition, it is explained that the driving shaft of the driving member 600 can also be connected through a gear assembly; at the same time, the material collecting rack 500 is vertically arranged, and the material collecting rack 500 is vertically rotatably connected to the frame 210 through a rotating shaft, and a second pulley 520 is fixed on the rotating shaft, and a first pulley 510 is arranged on the driving rod 233, and a driving belt 530 is wound around the outer sides of the first pulley 510 and the second pulley 520.

[0058] Specifically, when the driving member 600 drives the driving rod 233 to rotate, the driving member 600 drives the first pulley 510 to rotate through the driving rod 233, the first pulley 510 drives the second pulley 520 to rotate, and the second pulley 520 drives the material receiving rack 500 to rotate through the rotating shaft. Since the base tape 110 and the coating 120 are attached together and wound on the material receiving rack 500, during the rotation of the material receiving rack 500, the material receiving rack 500 quickly collects the base tape 110 and the coating 120, and then quickly collects the product 130. At the same time, the material receiving rack 500 provides a sufficiently large power to make the base tape 110 and the coating 120 continue to slide between the first pressing part 230 and the second pressing part 240, so as to quickly cover the product 130.

[0059] In some embodiments of the present invention, reference Figure 6 and Figure 7 The packaging machine further includes a base tape rack 300. The base tape rack 300 is vertically arranged and vertically rotatedly connected to the frame body 210 via a rotating shaft. The height of the base tape rack 300 is higher than the height of the plane plate 220. The base tape 110 is wound around the outside of the base tape rack 300, and the free end of the base tape 110 slides horizontally into the guide groove 221 through one end of the guide groove 221. Based on the need to make the base tape 110 slide horizontally into the guide groove 221, a first guide assembly 310 is fixed to the plane plate 220, and the first guide assembly 310 is located just above one end of the guide groove 221. The first guide assembly 310 is composed of two integrally arranged guide plates, namely a first guide plate 311 and a second guide plate 312. The first guide plate 311 is horizontally fixed on the plane plate 220 just above the guide groove 221, and the second guide plate 312 is smoothly connected to the side of the first guide plate 311 away from the second pressing portion 240. The side of the second guide plate 312 facing the guide groove 221 is a convex arc surface. The base belt 110 gradually slides to the lower side of the first guide plate 311 along the arc surface on the lower side of the second guide plate 312, so that the base belt 110 gradually slides horizontally into the guide groove 221 from the inclined state.

[0060] In a specific embodiment of the present invention, referring to Figure 6 and Figure 8 The packaging machine further comprises a film laminating frame 400, which is vertically arranged on the frame 210, and the film laminating frame 400 is vertically rotatably connected to the frame 210 at the upper side of the guide groove 221, and the film 120 is wound around the outer side of the film laminating frame 400, and the free end of the base band 110 slides horizontally into the guide groove 221. Based on the need to make the film 120 slide horizontally into the guide groove 221, a second guide assembly 410 is fixed on the plane plate 220, and the second guide assembly 410 is located between the second pressing part 240 and the first guide assembly 310. The second guide assembly 410 comprises a guide column 411 horizontally arranged on the upper side of the guide groove 221, and the axial direction of the guide column 411 is arranged perpendicular to the length direction of the guide groove 221, and the free end of the film 120 bypasses the side wall of the guide column 411 and slides horizontally into the guide groove 221, and is located at the upper side of the base band 110. In addition, the guide pillars 411 are respectively sleeved with fixed limiting rings 412 near their ends, and the two limiting rings 412 respectively limit the two sides of the coating 120 in the width direction.

[0061] In a further embodiment of the present invention, referring to Figure 6 and Figure 7, a conveying mechanism 800 is provided on the frame 210, and the conveying mechanism 800 is located between the first guide assembly 310 and the second guide assembly 410, and is used to convey the product 130 to the base belt 110. The conveying mechanism 800 includes a manipulator 810, a rotary cylinder 820, a rotary conveying part 830, and a vacuum suction nozzle 840. The manipulator 810 slides horizontally on the frame 210, and the manipulator 810 sucks the product 130 through its suction nozzle, and a driving component is provided on the frame 210, and the driving component drives the manipulator 810 to slide to the upper side of the base belt 110 (because the driving component and the manipulator 810 are conventional technical means known in the art, such as the driving component is a rodless cylinder, which will not be described in detail). The rotating cylinder 820 is horizontally arranged on the frame 210, and the rotating axis of the rotating cylinder 820 is located between the manipulator 810 and the base belt 110. The rotating axis of the rotating cylinder 820 is arranged perpendicular to the length direction of the guide groove 221, and the rotating conveying part 830 is sleeved and fixed on the rotating axis of the rotating cylinder 820. Two vacuum suction nozzles 840 are fixedly connected to the two ends of the rotating conveying part 830. Under the action of the vacuum source, the vacuum suction nozzles 840 can suck the product 130 on the manipulator 810. The rotating cylinder 820 drives the rotating conveying part 830 to rotate vertically, and the end of the rotating conveying part 830 rotates to the upper side of the base belt 110, so that the product 130 is placed on the base belt 110. Therefore, the rotating conveying part 830 reduces the conveying stroke of the manipulator 810, thereby allowing the product 130 to be quickly conveyed to the base belt 110.

[0062] In some embodiments of the present invention, the placement of the product 130 is further detected. A detector 900 is provided on the frame 210 just above the base belt 110. The detector 900 is used to detect the placement of the product 130. If the product 130 is placed facing upward, the product 130 is conveyed normally. If the product 130 is placed facing downward, the product 130 stops conveying.

[0063] In some embodiments of the present invention, reference Figure 6 and Figure 8, further, the coating 120 and the base tape 110 are smoothly conveyed to between the first pressing part 230 and the second pressing part 240, and a flattening mechanism 700 is arranged on the plane plate 220 between the second pressing part 240 and the second guide assembly 410. The flattening mechanism 700 includes a rotating seat 710, an elastic member 730, and a flattening wheel 720. The rotating seat 710 is vertically rotatably connected to the plane plate 220 through a rotating shaft, and the flattening wheel 720 is horizontally arranged on the rotating seat 710 and rotatably connected to the rotating seat 710. The axial direction of the flattening wheel 720 is perpendicular to the length direction of the guide groove 221, and the circumferential surface of the flattening wheel 720 abuts against the upper side of the coating 120, thereby flattening the coating 120 downward; at the same time, an elastic member 730 is connected between the rotating seat 710 and the plane plate 220, and the elastic member 730 has a downward elastic force on the rotating seat 710, so that the flattening wheel 720 is stably pressed on the upper side of the coating 120.
