[0034] When the sheet material in the first material placing plate 17 in work area is being extracted by the paper folding mechanism connected with rack 1, the part of whole conveying device 2 in material storage area can place the second material placing plate 24, which can be placed with standby sheet material under the assistance of preloading positioning mechanism 3;When the sheet material in the first material placing plate 17 in work area is extracted, the lifting platform 16 drops the first material placing plate 17 to the bottom of work area, at this time, the first material placing plate 17 can be taken out in time by artificial or robot, and the second material placing plate 24 is pushed into work area on whole conveying device 2, the lifting platform 16 lifts the second material placing plate 24, and the replenishment of sheet material is quickly completed.

[0035] Rack 1 includes two vertical side walls 11 arranged in parallel left and right, and a plurality of cross beams 12 arranged in parallel between the two side walls 11, so that the rack 1 forms a frame shape, and a driving motor 13 is arranged at the top of the frame, which drives the lifting platform 16 in the work area to lift or drop through a chain wheel 14 and a chain 15, and the lifting platform 16 is used for placing the material placing plate (17,24), and the sheet material can be placed on the material placing plate (17,24).

Figure 3 As shown in the figure, the lifting platform 16 is in the shape of a mountain-shaped frame, with a concave avoidance structure 161 arranged in the middle, for avoiding the whole conveying device 2 when dropping.

[0037] Figure 1 And Figure 2 As shown in the figure, the whole conveying device 2 includes a long strip-shaped base 21 and a roller assembly 22 arranged above the base 21, and the roller assembly 22 includes a pair of parallel arranged roller groups, each roller group is composed of a plurality of parallel arranged rollers, for rolling support of the material placing plate (17,24) loaded with sheet material stack.

[0039] It should be noted that the first discharge plate 17 and the second discharge plate 24 have the same structure, and they are used alternately when the sheet material conveying device is working. When the sheet material on the first discharge plate 17 is used up, the lifting platform 16 in the rack 1 lowers the first discharge plate 17 to the bottom, is separated from the lifting platform 16, is slid out of the overall conveying device 2 by manual or robot, is taken out at the gap in the middle of the rack 1, and then the second discharge plate 24 loaded with the sheet material stack is pushed to the working position of the original first discharge plate 17.

[0040] The overall conveying device 2 further comprises two pre-loading plate positioners 23 symmetrically arranged at the two ends of the bottom beam 12 of the rack 1 to position the discharge plate (17, 24) left and right on the overall conveying device 2, so that it is kept at a certain distance from the pre-loading positioning mechanism 3, thereby positioning the sheet material placed on the discharge plate (17, 24) left and right.

[0041] The overall conveying device 2 connects the working area and the storage area, overcomes the defect that the sheet material transmission between the working area and the storage area in the prior art adopts split conveying, and can greatly improve the conveying accuracy.

[0042] As shown in Figure 1 , Figure 2 and Figure 4 , the pre-loading positioning mechanism 3 comprises a pair of pre-loading positioning components which are the same in structure and shape. Each pre-loading positioning component comprises a pre-loading positioning plate 31, a driving rod 32, an auxiliary rod 33 and a connecting rod 34. The pre-loading positioning plate 31 is connected in parallel with the connecting rod 34 at the two ends of the driving rod 32 and the auxiliary rod 33, so that the pre-loading positioning plate 31, the driving rod 32, the auxiliary rod 33 and the connecting rod 34 form a frame shape. The two auxiliary rods 33 are parallel to the driving rod 32 and are located on the upper and lower sides of the driving rod 32. The two auxiliary rods 33 are slidably arranged on the front side of the column 18 of the rack 1 through a guide sliding device 331, and the driving rod 32 passes through a waist-shaped hole formed in the column 18. The driving rod 32 is driven by an adjusting mechanism 35 to drive the whole pre-loading positioning component to move left and right on the column 18.

[0043] The pre-loading positioning mechanism 3 is used to position the sheet material on the second discharge plate 24 in the storage area, so that all the sheet material can be placed in the correct position, and the sheet material on the second discharge plate 24 can immediately continue the original feeding process after being pushed into the working area.

[0044] The pre-positioning mechanism 3 is arranged on the upright 18 of the front side of the frame 1. In operation, the first feeding plate 17 inside the frame 1 is responsible for feeding the folding mechanism, and the second feeding plate 24 outside the frame 1 is placed on the roller assembly 22 at the end of the integral conveying device 2 of the storage area, and the sheet material of the storage area is stacked on the second feeding plate 24 after being positioned by the pre-positioning mechanism 3. When the sheet material on the first feeding plate 17 is used up, the second feeding plate 24 is pushed into the working area to replace the position of the first feeding plate 17.

[0045] As shown in Figure 5 The adjustment mechanism 35 is fixed on the upright 18, which includes a positioning large-range adjusting block 351, a pre-positioning fine-tuning block 352, and a pre-positioning avoidance power 353. One end of the positioning large-range adjusting block 351 is detachably fixed on the driving rod 32, and the other end is connected with a push-pull rod 3531 arranged on the pre-positioning fine-tuning block 352, wherein the push-pull rod 3531 is the actuating rod of the avoidance power 353, and the avoidance power 353 is arranged on the pre-positioning fine-tuning block 352. The main body 3521 of the pre-positioning fine-tuning block 352 is arranged on the upright 18 through a sliding rod 3522 and a fine-tuning screw rod 3523. By adjusting the fine-tuning screw rod 3523, the main body 3521 of the pre-positioning fine-tuning block 352 and the avoidance power 353 can slide left and right on the upright 18 along the sliding rod 3522, so as to realize the fine-tuning of the positions of the main body 3521 of the pre-positioning fine-tuning block 352 and the avoidance power 353.

[0046] Optionally, the pre-positioning avoidance power 353 is a pneumatic cylinder or a hydraulic cylinder, and can also be other forms of power. The pre-positioning avoidance power 353 can make the push-pull rod 3531 on it greatly extend and retract, drive the positioning large-range adjusting block 351 to move left and right, and then drive the driving rod 32 and the pre-positioning plate 31 to move left and right. When the pre-positioning components on the two uprights 18 move relatively close to each other, the sheet material between them can be positioned at a predetermined position, so as to realize the positioning of the pre-positioned sheet material.

[0047] In the utility model, the positioning large-range adjusting block 351 has large adjustment distance, fast speed, but low precision, and can be used for the preliminary adjustment of the positions of the pre-positioning components; the pre-positioning fine-tuning block 352 has small adjustment distance, slow speed, but high precision, and can be used for the accurate adjustment of the positions of the pre-positioning components.

[0048] When the size of the sheet material in production changes, for example, the size of the sheet material changes from 500mm to 1000mm, it is necessary to expand the distance between the two oppositely arranged pre-positioning plates 31, at which time it is necessary to adjust the large-range adjusting block 351 and the pre-positioning fine-tuning block 352.

[0049] In the adjustment, the displacement adjustment amount of the pre-installed positioning plate 31 on the left and right sides is generally the same, the connection between the large-scale adjustment block 351 on the left and right sides and the driving rod 32 is first loosened, the pre-installed positioning plate 31 on the left and right sides is manually pushed to a position about 250 mm close to the stand column 18, and then the two large-scale adjustment blocks 351 are locked on the corresponding driving rods 32; then the distance between the pre-installed positioning plates 31 on the left and right sides is adjusted to exactly 1000 mm through the fine adjustment screw rod 3523 on the left and right sides.

[0050] The above has described the various embodiments of the utility model, the above description is exemplary, is not exhaustive, and also is not limited to the disclosed various embodiments. Many modifications and changes are obvious to those skilled in the art without deviating from the scope and spirit of the described various embodiments. Therefore, the protection scope of the utility model should be the protection scope of claims.
