[0021] As a further configuration of the above scheme, the first actuating cylinder 41 and the second actuating cylinder 42 are fixed on the slider 29, and the slider 29 is also provided with a plurality of material columns 27 for constituting the shell bin 21 and limiting the material in the shell bin 21, and the bottom of the material column 27 is provided with an opening, and the opening prevents the material column 27 from limiting the falling of the material.

[0022] As a further arrangement of the above scheme, the push plate 23 is fixedly connected to the push plate frame 231, the first actuating cylinder 41 and the second actuating cylinder 42 are respectively provided with a unloading piston rod 40 and a connecting arm 49 fixed to the unloading piston rod 40, the push plate frame 231 is fixedly connected to the connecting arm 49, and the push plate 23 is driven to move by the first actuating cylinder 41 and the second actuating cylinder 42. Combined with the accompanying drawings, the first actuating cylinder 41 and the second actuating cylinder 42 can push the material from the bracket 22 to the conveyor belt 3 through the action of the push plate 23.

[0023] As a further arrangement of the above scheme, a limiting member 51 is further arranged on the slider 29 on one side of the second actuating cylinder 42.

[0025] As a further configuration of the above scheme, an air suction structure 31 is provided on the conveyor belt 3 , and a plurality of air holes are provided on the belt surface of the conveyor belt 3 for the air suction structure 31 to absorb and transport the materials on the conveyor belt 3 .

[0026] The utility model discloses an automatic shell unloading device for a book-type box assembly machine, which comprises a material unloading portion 2 arranged on a conveyor belt 3. The material unloading portion 2 can, through the mutual cooperation between a plurality of cylinders, place the materials stacked in layers in a shell bin 21 onto the conveyor belt 3 one by one, and ensure cooperation with the processing assembly behind the frame 1. For each action of the material, only one portion is placed for subsequent processing by the processing assembly, and the position of the material falling on the conveyor belt 3 is adjusted to make it consistent. Compared with the prior art, the shell unloading device of this embodiment can ensure that only one portion is placed each time, and there will be no problem of material jamming, and it can ensure that the position of the material placed each time is exactly the same, thereby ensuring smooth processing.

[0027] As mentioned above, the material discharge portion 2 of this embodiment includes a shell bin 21 for containing materials, and the shell bin 21 includes Figure 1-3 As shown, it is composed of four material columns 27 with angles at the four corners of the shell bin 21. It is worth noting that the material columns 27 are preferably set with four for the square structure material used in this embodiment. Further, the material column 27 of this embodiment is set on the slider 29, and as shown in the figure, two longitudinal tracks 11 and two transverse tracks 12 are set on the frame 1, and four sliders 29 are set on the bracket 22. Every two sliders 29 are grouped and respectively set in the slide groove 26 of a longitudinal track 11. Four sliders 29 are set on the two longitudinal tracks 11, and each slider 29 is integrated with a cylinder structure for horizontally pushing the material.

[0028] As mentioned above, the slider 29 on the longitudinal track 11 is relatively close to or away from the longitudinal track 11 to adjust the length of the material, and the two brackets 22 on each transverse track 12 are relatively close to or away from the longitudinal track 11 to control the width of the material.

[0029] The above-mentioned structure for positioning and fixing after adjustment adopts common bolts in the prior art, and its movement and fixation are controlled by loosening and tightening the bolts.

[0030] It is worth noting that in the solution adopted in this embodiment, a total of seven cylinders are set, including two first action cylinders 41, two second action cylinders 42, one positioning cylinder 43, and two positioning cylinders 44. Figure 1-3The first actuating cylinder 41 shown is arranged on a slider 29 on one of the longitudinal rails 11, while the second actuating cylinder 42 is arranged on the other side, and the side where the second actuating cylinder 42 is arranged is the side with a limit member 51, and the side where the first actuating cylinder 41 is arranged does not have a limit member 51. At the same time, two positioning cylinders 44 are also arranged in the space between the conveyor belt 3 and the lower part of the longitudinal rail 11 on the side with the limit member 51, and the positioning cylinder 43 is arranged next to the longitudinal rail 11 on the side away from the positioning cylinder 44, and the telescopic direction of its unloading piston rod 40 is the transmission direction of the conveyor belt 3.

[0031] It should be noted that the device of this embodiment can be adaptively adjusted according to different material sizes. When adjusting, it is only necessary to place the material in the shell bin 21, and then, by loosening the bolts, the longitudinal track 11 and the transverse track 12 can be adjusted one by one to the middle of the material. Figure 4 The width of the material shown should be smaller than the distance between the brackets 22 on both sides, and the bracket 22 is extended near the middle part to set a material table for receiving the material. The distance between the two material tables is larger than the width of the material, and the limiter 51 is adjusted up and down based on the waist-shaped hole 52 by loosening the screw 53, and then the screw 53 is fixed, so that the distance between the limiter 51 and the upper surface of the longitudinal track 11 is larger than the thickness of a single material and smaller than the thickness of two materials.

[0032] When the device of this embodiment is in use, the material is first placed in the shell bin 21 as described above, and then the device is started. First, based on the external air supply control, the unloading piston rods 40 of the first actuating cylinder 41 and the second actuating cylinder 42 are both extended outward by half of the telescopic stroke. After the device is officially operated and starts unloading, the first actuating cylinder 41 will be started at the same time as the second actuating cylinder 42, and the unloading piston rods 40 of both will move toward one side of the second actuating cylinder 42. At this time, the push plates 23 connected to the unloading piston rods 40 of the first actuating cylinder 41 and the second actuating cylinder 42 are linked based on the push plate frame 231, and then move to abut against one side of the material and push it away from the bracket 22 on the side of the first actuating cylinder 41. The material will As there is no bracket 22 at the bottom to support the material and let it fall obliquely onto the conveyor belt 3, the conveyor belt 3 is in a stopped state at this time. Subsequently, the first actuating cylinder 41 and the second actuating cylinder 42 act in opposite directions to push the bracket 22 on the other side of the material so that the material falls completely onto the conveyor belt 3. Subsequently, the two positioning cylinders 44 are started to push the fallen material toward the bracket 22 on the other side. The positioning cylinder 43 is started synchronously after the positioning cylinder 44 acts to push the material forward to move its position to the target point. Subsequently, the air suction structure 31 is started to adsorb the material from below to keep it in place. At this time, the conveyor belt 3 can start to transport the material forward, and in this process, the air suction structure 31 maintains the adsorption force to prevent the material from moving.

[0033] The above-mentioned structural setting is achieved through pre-adjustment. Each time the lower shell device performs a complete set of actions, only one portion of material is unloaded, and there will be no problem of double loading or failure to unload material. Therefore, problems such as material jamming in the transmission mechanism can be avoided. In addition, through the positioning and alignment settings, the air suction structure is started after the material is lowered to the conveyor belt to adjust the position of the material and maintain the adjusted position, so that the material can be adjusted in position before entering the processing station, which is convenient for rapid and automated processing.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
