[0036] Refer to Figures 3 to 6 , the material dispensing device according to the first aspect of the embodiment of the present invention is described below.

[0037] like Figures 3 to 6 As shown, a material dividing device includes a material transport line 100, a material dividing platform 200 and a material shifting assembly 300. The material transport line 100 transports the completed injection molded products in a single row. The material dividing platform 200 includes a first material table 210 and a second material table 220 which are oppositely arranged on both sides of the end of the material transport line 100. The table tops of the first material table 210 and the second material table 220 are connected to the assembly line, that is, the injection molded products can be pushed from the material transport line 100 to the first material table 210 or the second material table 220. The material shifting assembly 300 is arranged between the first material table 210 and the second material table 220, that is, it is located at the end of the material transport assembly line 100. The material shifting assembly 300 includes a transverse moving table 310, a material shifting piece 320, a first material blocking mechanism 330 and a second material blocking mechanism 340. The transverse moving table 310 can move between the first material table 210 and the second material table 220. The material shifting piece 320 is arranged at the bottom of the transverse moving table 310 and moves between the first material table 210 and the second material table 220 under the action of the transverse moving table 310 to push the material onto the first material table 210 or the second material table 220. The first material blocking mechanism 330 and the second material blocking mechanism 340 are arranged oppositely on both sides of the horizontal moving platform 310. The first material blocking mechanism 330 includes a first lifting driving member 331 and a first lifting baffle 332 connected to the first lifting driving member 331. The first lifting baffle 332 can perform lifting movement under the action of the first lifting driving member 331. The second material blocking mechanism 340 includes a second lifting driving member 341 and a second lifting baffle 342 connected to the second lifting driving member 341. The second lifting baffle 342 can perform lifting movement under the action of the second lifting driving member 341. The first lifting baffle 332 and the second lifting baffle 342 are respectively located on both sides of the material picking member 320. When the lifting baffle 332 is lowered to a table close to the material conveying line 100 or the first material table 210, the material tapping piece 320 and the first lifting baffle 332 form a first single-row channel. The material tapping piece 320 is in the shape of a long strip and is fixedly connected to the transverse moving table 310. When the first lifting baffle 332 and the first single-row channel formed by the material tapping piece 320 are aligned with the conveying direction of the material conveying line 100, the products fall into the single-row channel, and the material tapping piece 320 pushes the single-row products onto the first material table 210. The first lifting baffle 332 limits the single arrangement of the materials in the first single-row channel. Similarly, the second lifting baffle 342 and the material tapping piece 320 form a second single-row channel.

[0038] During specific implementation, the first lifting baffle 332 is in a lowered state, the first single-row channel is aligned with the material conveying line 100, and the products enter the first single-row channel from the material conveying line 100. After the products are filled, the lateral moving table 310 moves laterally toward the first material table 210, and the material shifting member 320 pushes the single-row products onto the first material table 210, forming a single row of products on the first material table 210 that is close to the material conveying line 100; the first lifting driving member 331 raises the first lifting baffle 332 to no longer restrain the products, and at the same time the second lifting driving member 341 lowers the second lifting baffle 342 to form a second single row channel with the material shifting member 320. The second single-row channel is now aligned with the material transport line 100. After the products are refilled, the material transfer piece 320 pushes the single-row products to the second material table 220, forming a single row of products on the second material table 220 that are close to the material transport line 100. This process repeats itself, and the single-row products pushed back will push the single-row products in the front row to move on the first material table 210 or the second material table 220, and finally the first material table 210 and the second material table 220 are stacked and filled. The left and right movement of the material transfer piece 320 and the lifting and lowering process of the first lifting baffle 332 and the second lifting baffle 342 are utilized to realize automatic material distribution of the products on the two platforms.

[0039] In some embodiments of the present invention, a material blocking baffle 110 is provided at the end of the material transport line 100. The material blocking baffle 110 is located at the end of the first single-row channel and the second single-row channel, and can be fixedly connected to the material transport line 100 by screw connection. After the products on the material transport line 100 enter the first single-row channel or the second single-row channel, they are blocked by the material blocking baffle and stacked individually to form a single-row product. The material blocking baffle 110 is arranged horizontally and close to or parallel to the end edges of the first material platform 210 and the second material platform 220, so that the material shifting member 320 can directly shift the single-row product to the first material platform 210 and the second material platform 220, which is beneficial to the product stacking process.

[0040] In some embodiments of the present invention, a plurality of transverse dividing strips 230 are provided on the first material platform 210 and the second material platform 220, and the setting direction of the transverse dividing strips 230 is perpendicular to the material conveying direction of the material conveying assembly line 100, and a single-row material collecting channel 240 is formed between adjacent transverse dividing strips 230. The number of single-row material collecting channels 240 provided on the first material platform 210 and the second material platform 220 is equivalent to the number of products contained in the first single-row channel or the second single-row channel. When the materials are transferred, the products enter the single-row material collecting channels 240 one by one, forming a single row and finally being neatly stacked on the first material platform 210 and the second material platform 220. In this embodiment, the single-row material collecting channels 240 of the first material platform 210 and the second material platform 220 are provided with four channels, and the stacked products are finally arranged in a 4*4 rectangular arrangement on the first material platform 210 and the second material platform 220, and the corresponding outer edges of the first material platform 210 and the second material platform 220 are provided with blocking edges to prevent the materials from continuing to move outward.

[0041] Specifically, a guide tip 231 is provided at one end of the transverse dividing strip 230 close to the material transport line 100, and the guide tips 231 of two adjacent transverse dividing strips 230 form a guide opening of a single-row material collecting channel 240. Individual products on a single row of products are guided from the guide opening into the single-row material collecting channel 240, thereby ensuring neat arrangement on the first material table 210 and the second material table 220.

[0042] More specifically, the material transfer member 320 moves laterally on both sides of the material transport line 100, and a temporary storage interval 250 is formed between all the horizontal dividing bars 230 of the first material table 210 or the second material table 220 and the material transport line 100. The temporary storage interval 250 can accommodate a single column of materials. When the single-row products in the first single-row channel or the second single-row channel are pushed onto the first material table 210 or the second material table 220, they are temporarily stored in the temporary storage interval 250 and push the front products into the single-row material collection channel 240.

[0043] In some embodiments of the present invention, the material shifting assembly 300 further includes a gantry 350, which is straddled on the material transporting assembly line 100, and a transverse driving member is provided on the gantry 350, and the transverse moving platform 310 is slidably connected to the gantry 350, and a transverse slide rail matched with the transverse moving platform 310 is provided on the gantry 350, and the transverse driving member is connected to the transverse moving platform 310 and drives the transverse moving platform 310 to move transversely. The first lifting driving member 331, the second lifting driving member 341 and the transverse driving member can be cylinders, and the transverse driving member can also be a motor and a ball screw structure.

[0044] In some embodiments of the present invention, a material stop mechanism 400 is provided on the material transport line 100. The material stop mechanism 400 prevents the materials on the first material table 210 and the second material table 220 from entering the material transfer assembly 300 when the materials are full. The first material table 210 and the second material table 220 are provided with corresponding full-load photoelectric sensors. The material stop mechanism 400 includes a material stop cylinder 410 and a material stop member 420 arranged on the material stop cylinder 410. The material stop cylinder 410 can push the material stop member 420 to cut off the materials on the material transport line 100 so that the products no longer enter the material transfer assembly 300. It can be triggered by the full-load photoelectric sensor, and the full-load photoelectric sensor is electrically connected to the material stop cylinder 410.
