[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] A raw material conveying device for packaging bag production, such as Figures 1-7 As shown, it includes a base frame 1, an arc-shaped protective cover 2, a guide pipe 3, a feeding mechanism, a unloading mechanism, and a feeding mechanism. The arc-shaped protective cover 2 is connected to the base frame 1. The guide pipe 3 is connected to the middle of the base frame 1. The left end of the guide pipe 3 passes through the left side of the base frame 1. The left outlet of the guide pipe 3 bends downward. The right end of the guide pipe 3 bends upward and passes through the arc-shaped protective cover 2. A feeding mechanism for conveying materials is installed on the base frame 1. The unloading mechanism is provided on the arc-shaped protective cover 2. The feeding mechanism is provided on the guide pipe 3.

[0031] like Figure 2 As shown, the feeding mechanism includes a screw feeding shaft 41 and a feeding motor 42. The feeding motor 42 is installed on the left side of the guide pipe 3. The screw feeding shaft 41 is connected to the output shaft of the feeding motor 42. The screw feeding shaft 41 is located inside the guide pipe 3. The rotation of the screw feeding shaft 41 can transport the raw materials inside the guide pipe 3.

[0032] like Figure 3 and Figure 4 As shown, the feeding mechanism includes a feeding hopper 51, a cross-shaped partition plate 52, a baffle plate 56, and a stirring assembly. The feeding hopper 51 is connected to the top right side of the arc-shaped protective cover 2. The cross-shaped partition plate 52 is installed inside the feeding hopper 51, dividing the interior of the feeding hopper 51 into four sections. The bottom of the feeding hopper 51 is connected to the right side of the guide pipe 3. The baffle plate 56 is slidably connected to the bottom of the feeding hopper 51, which can block the connection between the feeding hopper 51 and the guide pipe 3. The stirring assembly is provided on the cross-shaped partition plate 52, which is used to stir the raw materials.

[0033] like Figure 4As shown, the stirring assembly includes a drive motor 53, a rotating shaft 54, and a stirring frame 55. The drive motor 53 is installed at the top center of the cross partition plate 52. The rotating shaft 54 ​​is rotatably connected to the output shaft of the drive motor 53. The rotating shaft 54 ​​passes through the middle of the cross partition plate 52 and is rotatably connected to the cross partition plate 52. The stirring frame 55 is connected to the bottom of the rotating shaft 54 ​​and is located below the cross partition plate 52.

[0034] like Figures 5-7 As shown, the feeding mechanism includes a feeding frame 61, a connecting frame 62, a pushing frame 63, a pushing block 64, a control plate 65, and a blocking block 66. The feeding frame 61 is connected to the top of the guide pipe 3. The feeding frame 61 extends through the arc-shaped protective cover 2. The control plate 65 is slidably connected to the lower part of the feeding frame 61. Multiple discharge holes are evenly spaced on the control plate 65. The connecting frame 62 is connected to the left side of the control plate 65. The pushing frame 63 is connected to the upper rear side of the connecting frame 62. The pushing block 64 is connected to the output shaft of the drive motor 53. The pushing block 64 is located inside the pushing frame 63 so that the rotation of the pushing block 64 can contact the pushing frame 63 and squeeze the pushing frame 63 to move. Multiple sets of blocking blocks 66 are evenly spaced inside the feeding frame 61. The movement of the control plate 65 can align the discharge holes with the blocking blocks 66, so that the blocking blocks 66 block the discharge holes.

[0035] This conveying device can be used when raw materials need to be transported. In use, the raw materials are first added to the feeding hopper 51, and different raw materials are separated by the cross-shaped separator 52. Then, the plasticizer is added to the feeding frame 61. The raw materials fall to the bottom of the feeding hopper 51. Subsequently, the drive motor 53 is controlled to rotate the rotating shaft 54. The rotating shaft 54 ​​rotates, causing the agitator 55 to rotate. The agitator 55 agitates the raw materials, mixing them together. After mixing, the baffle plate 56 can be pulled forward, connecting the feeding hopper 51 to the guide pipe 3. The mixed material then enters the guide pipe 3. At this point, the feeding motor 42 can be controlled to rotate the spiral feeding shaft 41 to transport the material. Meanwhile, the drive motor 53 is operating... It can also drive the push block 64 to rotate. When the push block 64 rotates, it can repeatedly contact the push frame 63, thereby squeezing the push frame 63 to move back and forth. When the push frame 63 moves back and forth, it can drive the control plate 65 to move back and forth. When the control plate 65 moves, it can cause the block block 66 to repeatedly block the discharge hole. When the block block 66 does not block the discharge hole, the plasticizer can be discharged through the feeding frame 61 and added into the guide pipe 3 to realize the intermittent addition of the plasticizer. After the addition is completed, the spiral feeding shaft 41 continues to rotate and can discharge the mixed raw materials through the front side of the guide pipe 3, thereby realizing the effect of conveying the raw materials for packaging bag production. During the conveying process, the raw materials can be mixed without the need for an additional mixing process, making the operation more convenient.

[0036] like Figure 8 and Figure 9 As shown, it also includes a supplementary mechanism, which includes an annular guide rail 71, a rotating ring 72, a mounting frame 73, an electric push rod 74, a connecting rod 76, and a weighing component. The upper and lower parts of the outer side of the feeding hopper 51 are connected to the annular guide rail 71. The rotating ring 72 is rotatably connected to the annular guide rail 71. The mounting frame 73 is connected to the upper rotating ring 72. Electric push rods 74 are installed on both the left and right sides of the mounting frame 73. The telescopic rods of the two electric push rods 74 are connected to the connecting rods 76. The mounting sleeve 781 is slidably connected to the connecting rod 76. The weighing component is provided on the rotating ring 72.

[0037] like Figure 8 and Figure 9 As shown, the weighing assembly includes a placement tray 75, an electronic scale 79, a feeding hopper 77, and a geared motor 78. The placement tray 75 is connected to the rotating ring 72 below. The electronic scale 79 is mounted on the top of the placement tray 75. Mounting sleeves 781 are slidably connected to both connecting rods 76. The geared motor 78 is mounted on the mounting sleeves 781. The feeding hopper 77 is connected between the output shafts of the two geared motors 78 and is placed on the electronic scale 79.

[0038] When adding raw materials, the raw materials can be poured into the feeding hopper 77. Observe the changes in the data on the electronic scale 79 to see how much raw material has been added. After adding the appropriate amount of raw material, control the extension rod of the electric push rod 74 to move the placement plate 75 upward. The upward movement of the placement plate 75 can lift the feeding hopper 77. After lifting, control the operation of the reduction motor 78 to drive the feeding hopper 77 to rotate, thereby pouring the raw materials in the feeding hopper 77 into the unloading hopper 51 to realize the addition of raw materials. The quantity added can be weighed during addition. In actual operation, different raw materials need to be added to different sections of the unloading hopper 51. At this time, rotate the rotating ring 72 to drive the feeding hopper 77 to rotate, and adjust the position of the feeding hopper 77 to align with the upper section of the unloading hopper 51.

[0039] like Figure 10 As shown, it also includes a measuring mechanism, which includes a scale plate 81, a sliding rod 82 and a probe plate 83. The scale plate 81 is provided on the right side of the feeding frame 61, the sliding rod 82 is slidably connected to the right side of the feeding frame 61, and the probe plate 83 is connected to the left side of the sliding rod 82. The probe plate 83 is located inside the feeding frame 61.

[0040] When adding plasticizer into the feeding frame 61, the sliding rod 82 and the probe plate 83 can be pulled upwards first, and then the plasticizer can be added. After the addition is completed, the sliding rod 82 and the probe plate 83 are released. Under the action of gravity, the probe plate 83 moves down and falls on the surface of the plasticizer. As the amount of plasticizer in the feeding frame 61 decreases, the probe plate 83 and the sliding rod 82 gradually move downwards. The operator can then observe the position of the sliding rod 82 aligned with the scale plate 81 to observe the amount of plasticizer in the feeding frame 61.

[0041] like Figure 11 As shown, it also includes a discharge frame 91 and a screen 92. The front side of the guide pipe 3 is connected to the discharge frame 91, and the bottom of the discharge frame 91 is provided with a screen 92 for screening the raw materials after production. Qualified raw materials will pass through the screen 92, while unqualified raw materials will remain in the discharge frame 91, thereby screening the qualified and unqualified raw materials after production.

[0042] When the raw materials are conveyed out, they will enter the discharge frame 91. At this time, the qualified raw materials will fall through the screen 92, while the unqualified raw materials will remain in the discharge frame 91 and eventually be pushed out of the discharge frame 91, thereby achieving the effect of screening the conveyed raw materials.

[0043] like Figure 1As shown, it also includes a telescopic soft frame 10. The front side of the discharge frame 91 is connected to the telescopic soft frame 10. If the front side of the discharge frame 91 is not aligned with the feed end of the subsequent processing equipment, the telescopic soft frame 10 can be stretched to align with the feed end of the subsequent processing equipment, so that the unqualified material can be conveyed to the subsequent processing equipment through the guide of the telescopic soft frame 10.

[0044] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the invention without departing from the principles and spirit of the invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for illustrative purposes only and is not intended to limit the invention; rather, the scope of protection is defined by the content of the claims.
