[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figure 1 and Figure 2 As shown in the figure, a feeding mechanism for an intelligent gift bag threading machine according to an embodiment of the present invention includes a frame 1, an adsorption device 2, a positioning plate 6, and a glue applicator 4. The positioning plate 6, the adsorption device 2, and the glue applicator 4 are all connected to the frame 1. The adsorption device 2 and the glue applicator 4 are located on the front and rear sides of the positioning plate 6, respectively. Paper is stacked on the positioning plate 6.

[0025] Specifically, such as Figure 1 As shown, rubber-bottomed metal feet 11 and universal casters 12 are installed at the four corners of the lower end of the frame 1.

[0026] In this embodiment, paper is stacked using a positioning plate 6, and the adsorption device 2 lifts each stacked piece of paper and transfers it to the glue applicator 4, where the glue applicator 4 applies glue to the paper. Thus, by setting up the positioning plate 6, paper can be stored; the adsorption device 2 automatically transfers each piece of paper to the glue applicator 4; and the glue applicator 4 applies glue to the paper, reducing manual intervention in the gift bag loading process, thereby saving manpower and increasing work efficiency. Furthermore, by setting up the frame 1, it is convenient to install the positioning plate 6, the adsorption device 2, and the glue applicator 4.

[0027] Optionally, such as Figure 3 As shown, the glue applicator 4 includes a glue applicator bracket 41, a drive motor 42, a synchronous pulley 43, a synchronous belt 44, a drive roller 45, a glue applicator cylinder 46, and a glue applicator 47. The glue applicator bracket 41 is connected to the upper end of the frame 1. The output shaft of the drive motor 42 is drivenly connected to one of the synchronous pulleys 43, and the other synchronous pulley 43 is rotatably connected to the glue applicator bracket 41. The two synchronous belts 44 are drivenly connected through the synchronous belts 44. The drive roller 45 is axially oriented in the left-right direction. One end of the drive roller 45 is connected to the other synchronous pulley 43, and the other end of the drive roller 45 is rotatably connected to the lower end of the glue applicator bracket 41. The glue applicator cylinder 46 is connected to the upper end of the glue applicator bracket 41, and the output end of the glue applicator cylinder 46 is connected to the glue applicator 47. The glue applicator 47 is located above the drive roller 45.

[0028] In this embodiment, when the paper is passed between the glue applicator 47 and the drive roller 45, the glue applicator 47 is driven downward by the glue applicator cylinder 46, and the glue applicator 47 applies glue to the paper. Next, the drive motor 42 drives a synchronous pulley 43 to rotate, and the transmission relationship between the two synchronous pulleys 43 and the synchronous belt 44 drives another synchronous pulley 43 to rotate; the other synchronous pulley 43 is connected to the drive roller 45, driving the drive roller 45 to rotate, and the paper moves to the drive roller 45, and the rotation of the drive roller 45 drives the paper to move to a workstation.

[0029] Optionally, such as Figures 2 to 4As shown, the feeding mechanism of the intelligent gift bag threading machine also includes a lifting device 3. The lifting device 3 includes a lifting motor 31, a first transmission sprocket 321, a first transmission belt 322, a second transmission sprocket 323, a second transmission belt 324, and a transmission shaft 325. The lifting motor 31 is connected to the frame 1. The transmission shaft 325 is located inside the upper part of the frame 1. The output shaft of the lifting motor 31 is connected to the transmission shaft 325. The first transmission sprocket 321 is provided at both ends of the transmission shaft 325. The two second transmission sprockets 323 are rotatably connected to the left and right sides of the lower end of the frame 1, respectively. The left first transmission sprocket 321 and the left second transmission sprocket 323 are connected by the first transmission belt 322, and the right first transmission sprocket 321 and the right second transmission sprocket 323 are connected by the second transmission belt 324. The left and right sides of the positioning plate 6 are connected to the first transmission belt 322 and the second transmission belt 324, respectively. The paper is stacked on the positioning plate 6.

[0030] In this embodiment, the lifting motor 31 drives the transmission shaft 325 to rotate, thereby driving the first transmission sprockets 321 at both ends of the transmission shaft 325 to rotate. The transmission relationship between the left first transmission sprocket 321, the left second transmission sprocket 323, and the first transmission belt 322, and the connection between the first transmission belt 322 and the left side of the positioning plate 6, drives the left side of the positioning plate 6 to move vertically. Similarly, the transmission relationship between the right first transmission sprocket 321, the right second transmission sprocket 323, and the second transmission belt 324, and the connection between the second transmission belt 324 and the right side of the positioning plate 6, drives the right side of the positioning plate 6 to move vertically. This allows the height of the positioning plate 6 to be adjusted. When the paper stack is high, the positioning plate 6 can be lowered so that the adsorption device 2 is above the paper; when the paper stack is low, the positioning plate 6 can be raised so that the paper is close to the adsorption device 2. This allows the adsorption device 2 to easily adsorb the paper, facilitating paper feeding.

[0031] Optionally, such as Figures 2 to 4 As shown, the lifting device 3 further includes a first slide rail 331, a first slider 332, a second slide rail 333, a second slider 334, and a photoelectric sensor 34. The first slide rail 331 and the second slide rail 333 are respectively arranged on the left and right sides of the frame 1. The first slide rail 331 and the second slide rail 333 both extend in the vertical direction. The first slider 332 and the second slider 334 are respectively connected to the left and right sides of the positioning plate 6. The first slider 332 is slidably connected to the first slide rail 331, and the second slider 334 is slidably connected to the second slide rail 333. The photoelectric sensor 34 is arranged at both the upper and lower ends of the second slide rail 333.

[0032] In this embodiment, by providing a first slide rail 331 and a second slide rail 333 on the left and right sides of the frame 1 respectively, and by using a first slider 332 to slide on the first slide rail 331 and a second slider 334 to slide on the second slide rail 333, the positioning plate 6 can be stably raised and lowered. Furthermore, by providing photoelectric sensors 34 at the upper and lower ends of the second slide rail 333, the height of the positioning plate 6 can be limited, preventing the positioning plate 6 from rising too high or falling too low.

[0033] Optionally, such as Figure 1 and Figure 2 As shown, the feeding mechanism of the intelligent gift bag threading machine also includes a front limiting component 51 and a rear limiting component 52. The front limiting component 51 and the rear limiting component 52 are respectively connected to the front and rear ends of the frame 1. The front limiting component 51 and the rear limiting component 52 are used to limit the width of the paper.

[0034] In this embodiment, by setting a front limiting component 51 and a rear limiting component 52 on the front and rear sides of the frame 1, the front limiting component 51 can be used to limit the width of the front side of the paper, and the rear limiting component 52 can be used to limit the width of the rear side of the paper. This is beneficial for setting different sizes of paper on the positioning plate 6 according to different sizes of gift bags.

[0035] Optionally, such as Figures 2 to 4 As shown, the front limiting assembly 51 includes a front bracket 511, a front slide rail 512, a front slider 513, and a front limiting rod 514. The front bracket 511 is connected to the lower end of the frame 1, the front slide rail 512 is connected to the upper end of the front bracket 511 and extends in the left and right direction, the front sliders 513 are slidably connected to both sides of the front slide rail 512, and the two front sliders 513 are each connected to the vertically arranged front limiting rod 514. The front limiting hole 61 is opened at the front end of the positioning plate 6, and the upper ends of the two front limiting rods 514 pass through the front limiting hole 61. The front limiting hole 61 is elongated and extends in the left and right direction.

[0036] In this embodiment, two front sliders 513 move on the front slide rail 512, causing two front limiting rods 514 to move left and right within the front limiting hole 61. This allows adjustment of the distance between the upper ends of the two front limiting rods 514, positioning the front end of the paper between the upper ends of the two front limiting rods 514, thus limiting the width of the paper's front end. Furthermore, the front bracket 511 facilitates the installation of the front slide rail 512.

[0037] Optionally, such as Figures 2 to 4As shown, the front limiting assembly 51 also includes a trapezoidal lead screw 515, nuts 516 and a handwheel 517. The trapezoidal lead screw 515 is axially oriented to the left and right and its two ends pass through the left and right ends of the front bracket 511 respectively and are connected to the handwheel 517. Two nuts 516 are threaded on the trapezoidal lead screw 515, and the two front sliders 513 are connected to the two nuts 516 in a one-to-one correspondence.

[0038] Specifically, such as Figures 2 to 4 As shown, adjustable L-shaped handles 518 are provided on both the left and right ends of the front bracket 511.

[0039] In this embodiment, the handwheel 517 is rotated to drive the trapezoidal screw 515 to rotate relative to the front bracket 511, which in turn drives the two nuts 516 to move in the left and right directions on the trapezoidal screw 515. The two nuts 516 are respectively connected to the two front sliders 513 one by one, which drives the two front sliders 513 to move in the left and right directions, thereby driving the two front limit rods 514 to move in the left and right directions within the front limit hole 61.

[0040] Optionally, such as Figure 4 As shown, the rear limiting assembly 52 includes a rear support 521, a sliding rod 522, a rear slider 523, and a rear limiting rod 524. The rear support 521 is connected to the upper end of the frame 1. The sliding rod 522 is connected to the lower end of the rear support 521 and extends in the left-right direction. Two rear sliders 523 are slidably connected to the sliding rod 522. Each of the two rear sliders 523 is connected to a vertically arranged rear limiting rod 524. The rear end of the positioning plate 6 has a rear limiting hole 62. The lower ends of the two rear limiting rods 524 pass through the rear limiting hole 62. The rear limiting hole 62 is elongated and extends in the left-right direction.

[0041] In this embodiment, two rear sliders 523 move on the lower sliding rod 522, causing two rear limiting rods 524 to move left and right within the rear limiting hole 62. This allows adjustment of the distance between the lower ends of the two rear limiting rods 524, positioning the rear end of the paper between the upper ends of the two front limiting rods 514, thus limiting the width of the rear end of the paper. Furthermore, the rear bracket 521 facilitates the installation of the lower sliding rod 522.

[0042] Optionally, such as Figure 4 As shown, the rear limiting assembly 52 also includes an upper sliding rod 525, a connecting rod 526, and an upper sliding block 527. The upper sliding rod 525 is connected to the upper end of the rear bracket 521 and extends in the left and right direction. The upper sliding block 527 is slidably connected to the upper sliding rod 525. The front end of the connecting rod 526 is connected to the adsorption device 2, and the rear end of the connecting rod 526 is connected to the upper sliding block 527.

[0043] In this embodiment, by setting an upper sliding rod 525, the upper slider 527 is slidably connected to the upper sliding rod 525, which can drive the connecting rod 526 and the adsorption device 2 to move synchronously in the left and right direction, making it easier to align the adsorption device 2 with the paper, and facilitating the adsorption of the paper by the adsorption device 2.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
