[0029] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0030] A raw material conveying device for packaging bag production, as Figures 1-7 shown, includes a chassis 1, an arc-shaped protective cover 2, a guide pipe 3, a feeding mechanism, a discharging mechanism and a feeding mechanism. The arc-shaped protective cover 2 is connected to the chassis 1, the guide pipe 3 is connected to the middle of the chassis 1, the left end of the guide pipe 3 passes through the left side of the chassis 1, the left discharging port 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 chassis 1, a discharging mechanism is provided on the arc-shaped protective cover 2, and a feeding mechanism is provided on the guide pipe 3.

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

[0032] As Figure 3 and Figure 4 shown, the discharging mechanism includes a discharging bucket 51, a cross partition board 52, a baffle plate 56 and a stirring assembly. The discharging bucket 51 is connected to the top right side of the arc-shaped protective cover 2. A cross partition board 52 is arranged inside the discharging bucket 51. The cross partition board 52 divides the inside of the discharging bucket 51 into four partitions. The bottom of the discharging bucket 51 is communicated with the right side of the guide pipe 3. A baffle plate 56 is slidably connected to the bottom of the discharging bucket 51. The baffle plate 56 can block the connection between the discharging bucket 51 and the guide pipe 3. A stirring assembly is provided on the cross partition board 52, and the stirring assembly is used for stirring the raw materials.

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

[0034] As Figures 5-7 shown, the feeding mechanism includes a blanking frame 61, a connecting frame 62, a pushing frame 63, a pushing block 64, a material control plate 65, and a blocking block 66. The blanking frame 61 is connected to the top of the guiding pipe 3. The blanking frame 61 passes through the arc-shaped protective cover 2. A material control plate 65 is slidably connected to the lower part of the blanking frame 61. A plurality of discharge holes are evenly spaced on the material control plate 65. A connecting frame 62 is connected to the left side of the material control plate 65. A pushing frame 63 is connected to the rear side of the upper part of the connecting frame 62. A pushing block 64 is connected to the output shaft of the driving motor 53. The pushing block 64 is located in the pushing frame 63, so that when the pushing block 64 rotates, it can contact and squeeze the pushing frame 63 to move. A plurality of groups of blocking blocks 66 are evenly spaced and connected in the blanking frame 61. When the material control plate 65 moves, the discharge holes can be aligned with the blocking blocks 66, so that the blocking blocks 66 block the discharge holes.

[0035] When it is necessary to convey raw materials, this conveying device can be used. During use, the raw materials can be first added into the feeding hopper 51, and different raw materials can be separated by the cross partition plate 52. Then, the plasticizing agent is added into the feeding frame 61. The raw materials will fall to the lower part of the feeding hopper 51. Subsequently, the driving motor 53 can be controlled to operate to drive the rotating shaft 54 to rotate. When the rotating shaft 54 rotates, it will drive the stirring frame 55 to rotate. When the stirring frame 55 rotates, it can stir the raw materials so that the raw materials are mixed together. After mixing, the blocking plate 56 can be pulled forward to connect the feeding hopper 51 and the guiding pipeline 3. The mixed materials will then enter the guiding pipeline 3. At this time, the feeding motor 42 can be controlled to operate to drive the spiral feeding shaft 41 to rotate to convey the materials. When the driving motor 53 operates, it can also drive the pushing block 64 to rotate. When the pushing block 64 rotates, it can repeatedly contact the pushing frame 63, thereby squeezing the pushing frame 63 to move back and forth. When the pushing frame 63 moves back and forth, it can drive the material control plate 65 to move back and forth. When the material control plate 65 moves, it can make the blocking block 66 repeatedly block the discharge hole. When the blocking block 66 does not block the discharge hole, the plasticizing agent can be discharged through the feeding frame 61 and then added into the guiding pipeline 3 to realize the intermittent addition of the plasticizing agent. After the addition is completed, the spiral feeding shaft 41 continues to rotate to discharge the mixed raw materials from the front side of the guiding pipeline 3, thus realizing the effect of conveying the raw materials for producing packaging bags. And during the conveying process, the raw materials can be mixed without the need for an additional mixing process, making the operation more convenient.

[0036] As Figure 8 and Figure 9 shown, it further includes a replenishing mechanism. The replenishing mechanism 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 both connected with an annular guide rail 71. The annular guide rail 71 is rotatably connected with a rotating ring 72. The rotating ring 72 above is connected with a mounting frame 73. Electric push rods 74 are installed on both the left and right sides of the mounting frame 73. Connecting rods 76 are connected to the telescopic rods of the two electric push rods 74. An installation sleeve 781 is slidably connected to the connecting rod 76. A weighing component is provided on the rotating ring 72.

[0037] As Figure 8 and Figure 9 shown, the weighing component includes a placing tray 75, an electronic scale 79, a feeding bucket 77 and a reduction motor 78. The rotating ring 72 below is connected with a placing tray 75. An electronic scale 79 is installed on the top of the placing tray 75. Installation sleeves 781 are slidably connected to both connecting rods 76. A reduction motor 78 is installed on the installation sleeve 781. A feeding bucket 77 is connected between the output shafts of the two reduction motors 78. The feeding bucket 77 is placed on the electronic scale 79.

[0038] When adding raw materials, the raw materials can be poured into the feeding bucket 77. Observe how much raw materials are added according to the change of the data on the electronic scale 79. After adding the appropriate amount of raw materials, control the telescopic rod of the electric push rod 74 to extend and drive the placing plate 75 to move upward. The upward movement of the placing plate 75 can lift the feeding bucket 77. After being lifted, control the operation of the reduction motor 78 to drive the feeding bucket 77 to rotate, so as to pour the raw materials in the feeding bucket 77 into the discharging bucket 51, so as to realize the addition of raw materials, and the added quantity can be weighed during the addition. During the actual operation process, different raw materials need to be added to different partitions in the discharging bucket 51. At this time, rotate the rotating ring 72 to drive the feeding bucket 77 to rotate, and adjust the feeding bucket 77 to align with the position of the partition on the discharging bucket 51.

[0039] As Figure 10 shown, it also includes a measuring mechanism. The measuring mechanism includes a scale plate 81, a sliding rod 82 and a detection plate 83. The scale plate 81 is arranged on the right side of the discharging frame 61. The sliding rod 82 is slidably connected to the right side of the discharging frame 61. The left side of the sliding rod 82 is connected with the detection plate 83. The detection plate 83 is located in the discharging frame 61.

[0040] When adding plasticizer to the discharging frame 61, the sliding rod 82 and the detection plate 83 can be pulled upward first, and then the plasticizer addition work can be carried out. After the addition is completed, release the sliding rod 82 and the detection plate 83. Under the action of gravity, the detection plate 83 moves downward and lands on the surface of the plasticizer. As the plasticizer in the discharging frame 61 decreases, the detection plate 83 and the sliding rod 82 gradually move downward, and the staff can observe the position where the sliding rod 82 aligns with the scale plate 81 to observe the quantity of the plasticizer in the discharging frame 61.

[0041] As Figure 11 shown, it also includes a discharging frame 91 and a sieve mesh 92. The discharging frame 91 is connected to the front side of the guiding pipeline 3. The sieve mesh 92 is arranged at the bottom of the discharging frame 91, which is used for screening the raw materials after production. The qualified raw materials will pass through the sieve mesh 92, while the unqualified raw materials will remain in the discharging frame 91, so as to screen the qualified and unqualified raw materials after production.

[0042] When the raw materials are conveyed out, the conveyed raw materials will enter the discharging frame 91. At this time, the raw materials with qualified size will pass through the sieve mesh 92 and fall, while the unqualified raw materials will remain in the discharging frame 91 and will be finally pushed out of the discharging frame 91, so as to realize the effect of screening the conveyed raw materials.

[0043] As Figure 1As shown, it further includes a telescopic flexible frame 10. The telescopic flexible frame 10 is connected to the front side of the discharge frame 91. If the front side of the discharge frame 91 is not aligned with the feeding end of the subsequent processing equipment, the telescopic flexible frame 10 can be stretched to align with the feeding end of the subsequent processing equipment, so that the unqualified materials can be guided and conveyed through the telescopic flexible frame 10 into the subsequent processing equipment.
