Accordingly, each roll of material 11 corresponds to a seed coating area, i.e. to the previous perforating wheel 43, rolling suction assembly. In order to facilitate fixing, the material belt shaft 71 is further provided with a plurality of locking blocks 8, the locking blocks 8 are clamped on two sides of each material belt 11, so that the position of the material belt 11 is kept fixed, the locking blocks 8 are in threaded connection with locking bolts, and the locking bolts penetrate through the locking blocks 8 and are movably abutted against the outer wall of the material belt shaft 71.

Meanwhile, the glue dispensing mechanism 6 comprises a glue hopper 61 and a plurality of glue dispensing heads 62 communicated with the glue hopper 61, one of the guide auxiliary shafts 73 guides the tape 11 to be under the glue dispensing heads 62, the glue dispensing heads 62 perform intermittent glue dispensing corresponding to two sides of the edge of the tape 11, the speed of the glue dispensing heads 62 of the embodiment is adjusted by a switch valve, the glue dispensing speed is adjustable, the glue dispensing heads 62 are kept vertical generally, and the glue is ensured to stably drop on the tape 11. And then the material belt 11 with the glue is pressed and bonded with the bottom layer film material 10 with the seeds under the film pressing shaft 72, and the film covering is completed.

The specific implementation and manufacturing process is as follows:

firstly, the wound bottom layer film material 10 is fixed on the feeding shaft 2 in a rotating way, and the bottom layer film material 10 is pulled out and spread on a conveying plane for continuous uniform-speed conveying. The bottom layer film material 10 firstly enters the prepressing mechanism 9, and the bottom layer film material 10 passes through the space between the first pressing shaft 91 and the second pressing shaft 92 and is flattened in advance under the action of the first pressing shaft 91 and the second pressing shaft 92, so that the bottom layer film material 10 can move forward more stably and tidily without fluctuation.

Then, the flattened bottom layer film 10 enters the punching mechanism 4, the bottom layer film 10 passes through between the first rotating shaft 41 and the second rotating shaft 42, namely continuously rolls through between the punching wheel 43 and the matching wheel 44, and the punching wheel 43 and the matching wheel 44 are matched with the convex pricks and the grooves to punch holes, so that the bottom layer film 10 forms a plurality of punched seed film coating areas.

The bottom layer film material 10 after the punching enters the adsorption mechanism 5, and each rolling adsorption component corresponds to each punched seed film coating area. The roller 52 for adsorbing and seeding uses the adsorption port 54 of the rotating part 56 to adsorb the seeds on the seed tray 53 on the circumferential outer wall of the roller 52, when the adsorption port 54 rotates to the position of the seed tray 53, the seeds are adsorbed immediately, the amount of the adsorbed seeds is usually not more than three, when the adsorption port 54 with the seeds rotates to the bottommost part, the adsorption port 54 is loosened, the seeds are put on the bottom layer film material 10, and the operation is repeated, so that the seeds are placed on the perforated seed film covering area on the bottom layer film material 10 in a limited distance and limited quantity.

Then, the reels on the reel shaft 71 pass around the guiding auxiliary shafts 73 and are pressed by the pressing film shaft 72 against the conveying plane of the conveyor 1, each reel 11 being individually associated with a film covering area on which a seed is placed. One of the guiding auxiliary shafts 73 guides the tape 11 to a position right below the dispensing head 62, the dispensing head 62 intermittently dispenses the adhesive corresponding to two sides of the edge of the tape 11, each tape 11 is provided with two dispensing openings, and the dispensing openings dispense the adhesive on two edges of the tape 11.

And then the dispensing tape 11 covers the tape adhesive side of the tape on the film laminating area with the seeds on the bottom layer film material 10, and simultaneously the tape 11 and the bottom layer film material 10 are pressed and bonded through the film pressing shaft 72 to complete the film laminating of the seeds.

Finally, the film materials after film covering are separated from the conveying plane and then are uniformly rolled on the material rolling shaft 3, the whole manufacturing process in one period is completed, automatic continuous production can be realized, and synchronous production and rolling can be realized.
