[0027] As Figure 1 shown, the utility model provides a trademark paper stack suction device. The trademark paper stack suction device includes mounting plate 2, controller, suction mechanism and folding plate 1, wherein one part suction disc body 3 of suction mechanism is spacedly distributed on the bottom surface of mounting plate 2, and the other part suction disc body 3 of suction mechanism is spacedly distributed on the bottom surface of folding plate 1. Folding plate 1 can rotate and position between unfolded position and folded position relative to mounting plate 2, when folding plate 1 is located in folded position, folding plate 1 is located above mounting plate 2, when folding plate 1 is located in unfolded position, the bottom surface of folding plate 1 keeps in the same plane with the bottom surface of mounting plate 2 to form first suction area at the bottom surface of mounting plate 2 and second suction area extending from the bottom surface of folding plate 1 to the bottom surface of mounting plate 2, and the boundary of second suction area and first suction area is located below mounting plate 2. Controller is signal connected with suction mechanism to be able to control the operation of suction disc body 3.

[0028] Specifically, when the packaging speed of the packaging machine is not high, the folding plate 1 is in the folded position, and only the suction disc body 3 on the mounting plate 2 is used to suck the trademark paper stack. When the packaging speed of the packaging machine is increased, the folding plate 1 is rotated relative to the mounting plate 2 until the bottom surface of the folding plate 1 is coplanar with the bottom surface of the mounting plate 2, and the folding plate 1 enters and is fixed in the unfolded position. At this time, the suction disc bodies 3 on the mounting plate 2 and the folding plate 1 can be used to suck the trademark paper stack. And the bottom surface of the mounting plate 2 and the bottom surface of the folding plate 1 form a first suction area and a second suction area. The suction disc in the first suction area can suck the first trademark paper stack, and the suction disc in the second suction area can suck the second trademark paper stack. Part of the second trademark paper stack is located at the bottom surface of the folding plate 1, and the other part of the second trademark paper stack is located at the bottom surface of the mounting plate 2. The mounting plate 2 can bear part of the weight of the second trademark paper stack. In summary, when the folding plate 1 is in the folded position, the suction disc on the mounting plate 2 can only suck one trademark paper stack. When the folding plate 1 is in the unfolded position, the folding plate 1 and the mounting plate 2 can simultaneously suck two trademark paper stacks, thereby increasing the supply amount of the trademark paper stack. Therefore, the trademark paper stack suction device of the utility model can simultaneously suck two trademark paper stacks for supply in the case that the processing speed of the packaging machine is improved, thereby preventing the case that the packaging machine is forced to pause due to insufficient trademark paper supply, and avoiding limiting the improvement of the packaging efficiency of the trademark paper packaging production line.

[0029] It should be noted that the suction disc body 3 of the second suction area includes all the suction disc bodies 3 of the folding plate and part of the suction disc bodies 3 of the mounting plate 2.

[0030] In addition, the utility model can add the rotatable and positionable folding plate 1 to the original trademark paper stack suction device (on the side of the original mounting plate 2) on the basis of retaining the original trademark paper stack suction device, so that the suction amount can be improved at a lower cost.

[0031] In some embodiments of the utility model, the number of folding plates 1 is two, and the two folding plates 1 are respectively arranged on the two sides of the length direction of the mounting plate 2.

[0032] Specifically, when the two folding plates 1 are in the unfolded position, the trademark paper stack suction device can simultaneously suck three trademark paper stacks to cope with the further improvement of the packaging efficiency of the packaging machine. At this time, the bottom surfaces of the mounting plate 2 and the folding plate 1 form a first suction area and two second suction areas. The two second suction areas are respectively located on the two sides of the first suction area, and the boundaries of the two second suction areas and the first suction area are both below the mounting plate 2. The three areas each form a complete trademark paper stack suction position, and the three trademark paper stack suction positions can simultaneously suck three trademark paper stacks.

[0033] In some embodiments of the utility model, when the folding plate 1 is in the folded position, the bottom surface of the folding plate 1 is perpendicular to the bottom surface of the mounting plate 2.

[0034] Specifically, when the single adsorption capacity does not need to be increased by the folding plate 1, the folding plate 1 is located in the folded position, at this time, the folding plate 1 is located above the mounting plate 2 and the bottom surface thereof is perpendicular to the bottom surface of the mounting plate 2, so as to avoid the folding plate 1 from hindering the adsorption work of the suction cup body 3 on the mounting plate 2 when the trademark paper stack is adsorbed.

[0035] In some embodiments of the utility model, the trademark paper stack suction device further comprises a rotating driver, a rotating rod 4 and two limiting blocks 41, the two ends of the rotating rod 4 are respectively erected on the top surface of the mounting plate 2 through the two limiting blocks 41, the rotating rod 4 is fixedly connected with the folding plate 1, the rotating driver can drive the rotating rod 4 to rotate circumferentially relative to the limiting block 41; in the case that the rotating driver stops driving, the rotating rod 4 can be positioned and locked by the positioning mechanism 5.

[0036] Specifically, the folding plate 1 is connected to the top surface of the mounting plate 2 through the rotating rod 4, when the rotating driver drives the rotating rod 4 to rotate, the folding plate 1 fixedly connected with the rotating rod 4 will rotate together, when the folding plate 1 enters the unfolded position or the folded position, the rotating driver stops driving, and the positioning mechanism 5 positions and locks the rotating rod 4 to fix the position of the folding plate 1.

[0037] In some embodiments, the rotating rod 4 can be directly connected with the rotating motor with positioning function, so as to realize the rotation and positioning of the rotating rod 4.

[0038] In some embodiments of the utility model, the middle part of the rotating rod 4 is sleeved with a first bevel gear 42, and the two first bevel gears 42 face each other in the length direction of the mounting plate 2; a top surface of the mounting plate 2 is erected with two transmission rods 43 corresponding to the two first bevel gears 42 one by one, and the two transmission rods 43 are collinear, a first end of the transmission rod 43 is engaged with the corresponding first bevel gear 42 through a second bevel gear 44; a driving rod 45 perpendicular to the transmission rod 43 is arranged between the second ends of the two transmission rods 43, the two ends of the driving rod 45 are rotatably connected to the top surface of the mounting plate 2 through the limiting block 41, a transmission motor 47 is arranged on the mounting plate 2, the transmission motor 47 is connected with one end of the driving rod 45, and the second bevel gears 44 of the second ends of the two transmission rods 43 are engaged with the driving bevel gear 46 in the middle part of the driving rod 45.

[0039] Specifically, the driving motor drives the driving rod 45 connected therewith to rotate, so that the two transmission rods 43 connected with the driving rod 45 rotate, thereby driving the rotating rod 4 sleeved with the first bevel gear 42 to rotate, and further driving the folding plate 1 to rotate. The driving motor can make the driving rod 45 rotate forward or reverse, so that the folding plate 1 can be switched between the unfolded position and the folded position.

[0040] As Figure 3As shown, in some embodiments of this utility model, positioning mechanisms 5 are provided at both ends of the rotating rod 4. The positioning mechanism 5 includes a telescopic block 51 and a fixing ring 52 installed on the top surface of the mounting plate 2. The fixing ring 52 is arranged around the limiting section of the rotating rod 4, and the inner wall of the fixing ring 52 is provided with a plurality of spaced blocking teeth 53. The telescopic block 51 is arranged on the limiting section of the rotating rod 4. The telescopic block 51 is connected to the transmission rod 43 by a spring. The spring can cause the telescopic block 51 to be biased toward the space between the blocking teeth 53, so that the telescopic block 51 can be inserted into the space between the blocking teeth 53. The telescopic block 51 can be inserted between any two blocking teeth 53 based on the elastic force of the spring to lock the rotating rod 4. Based on the driving force of the transmission motor 47, the rotating rod 4 can overcome the resistance between the blocking teeth 53 and the telescopic block 51 and rotate.

[0041] Specifically, when the rotating rod 4 rotates, the telescopic block 51 contacts and compresses the blocking tooth 53. The spring is compressed by the blocking tooth 53, causing the telescopic block 51 to contract in the opposite direction, allowing the telescopic block to pass over the blocking tooth 53. During rotation, the telescopic block 51 contracts once each time it contacts a blocking tooth 53, allowing it to rotate together with the rotating rod 4 within the fixed ring 52. When the folding plate 1 enters the unfolded or folded position, the drive motor stops, causing the rotating rod 4 to stop rotating. The telescopic block 51 is no longer compressed by the blocking tooth 53, allowing the spring to return to its natural state. The telescopic block 51 then inserts into the space between the blocking teeth 53, thus achieving the positioning of the folding plate 1.

[0042] It should be noted that the folding plate 1, after being positioned, needs to work together with the mounting plate 2 to achieve its adsorption of the trademark paper stack.

[0043] In some embodiments of this utility model, the suction mechanism includes a suction pump. The suction pump is connected to the suction cup body 3 on the mounting plate 2 through a first pipe. The suction pump is connected to the suction cup body 3 on the folding plate 1 through a second pipe. The controller can control the connection or closure of the first pipe and the second pipe through the solenoid valves set on the first pipe and the second pipe, respectively. The controller is signal-connected to the suction pump to control the operation of the suction pump.

[0044] Specifically, through the above settings, the controller can achieve independent control of all suction cup bodies 3.
