DETAILED DESCRIPTION

[0042] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] Example 1:

[0044] See also Figure 1-6 .

[0045] The cover feeding mechanism of the inner box machine includes:

[0046] The silo 1 is used to store stacked canopies 103 and has a discharge port 11 at the bottom;

[0047] The material stealing mechanism 2 is provided below the silo 1 and is used to take out the bottommost sky cover 103 from the bottom of the discharge port 11 and flip the sky cover 103 over and then add it to the ground cover 101 and the combination 102 of the inner mold and the surrounding strips;

[0048] The turning mechanism 3 is used to drive the material stealing mechanism 2 to turn over.

[0049] The stacked sky covers 103 are placed in the hopper 1, and the bottom sky cover 103 is taken out from the bottom of the discharge port 11 through the stealing mechanism 2. At this time, the ink side of the sky cover 103 faces upward and the non-ink side faces downward. In order to facilitate the use of the sky cover 103, the posture of the sky cover 103 needs to be changed. The stealing mechanism 2 is driven to flip through the flipping mechanism 3, so that the ink side of the sky cover 103 faces downward. Then the sky cover 103 is added to the ground cover 101 and the combination 102 of the inner mold and the surrounding strip for assembly. During the transfer process, the ink surface of the sky cover 103 does not rub against the adjacent upper material or between the mechanisms, and the ink is not contaminated.

[0050] like Figure 1-2 and Figure 6 As shown, in one embodiment, the material stealing mechanism 2 includes a suction cup 21 for adsorbing the lowermost canopy 103, a connecting shaft 22 provided on the suction cup 21, and a first power member for driving the connecting shaft 22 to move up and down.

[0051] With this design, by setting up the suction cup 21, the canopy 103 can be adsorbed, and by setting up the first power member, the suction cup 21 can be driven to move vertically. Under the action of the connecting shaft 22, the suction cup 21 can be rotated. Only one set of the stealing mechanism 2 is required to realize the transfer between the upper and lower positions, and the posture changes, and the cost of implementation is low.

[0052] like Figure 1-2 and Figure 6 As shown, as a preferred embodiment of the flipping mechanism 3, the flipping mechanism 3 includes a mounting plate 31 provided below the silo 1 and provided with a track groove 32, and a follower wheel 33 slidably provided in the track groove 32 and connected to the connecting shaft 22, and the mounting plate 31 is connected to the connecting shaft 22 via a guide rail pair 23. In this design, by providing the track groove 32 on the mounting plate 31 and providing the follower wheel 33 connected to the connecting shaft 22 in the track groove 32, the connecting shaft 22 and the suction cup 21 can be moved along the path of the track groove 32, and by providing the guide rail pair 23 and connecting the connecting shaft 22, the connecting shaft 22 is rotatably connected to the slider in the guide rail pair 23, thereby ensuring the vertical movement of the connecting shaft 22; the mechanical structure cost of the driving method of this flipping mechanism 3 is low and can convert linear motion into curved motion, the mechanical action is smoother and more efficient.

[0053] As a preferred embodiment, Figure 2 As shown, the track groove 32 includes upper and lower linear grooves 321 and a semicircular groove 322 connecting the two linear grooves 321. This design facilitates the vertical movement of the suction cup 21 to remove the canopy 103 from the hopper 1 and facilitates the vertical movement of the suction cup 21 to absorb the canopy 103 and place it into the third station 64. The provision of the semicircular groove 322 allows the connecting shaft 22 to rotate along with the follower wheel 33, thereby flipping the suction cup 21 so that the canopy 103 faces the ink side downward when placed in the third station 64.

[0054] like Figure 5 As shown, the present invention further includes a storage mechanism 4 provided on one side of the silo 1 for storing multiple stacks of canopies 103, a pushing mechanism 5 for pushing the canopies 103 in the storage mechanism 4 to the transfer mechanism 7, and a material shifting assembly 8 for shifting the canopies stored in the transfer mechanism 7 into the silo 1. With this design, by providing the transfer mechanism 7, it is possible to temporarily store the entire stack of canopies 103 pushed out of the storage mechanism 4, and by providing the material shifting assembly 8, it is possible to shift the entire stack of canopies 103 temporarily stored in the transfer mechanism 7 into the silo 1, thereby achieving automatic and continuous replenishment of the entire stack.

[0055] like Figure 5 As shown, preferably, a groove 83 is provided on the bottom plate of the transfer bin 71 below the canopy 103, and the toggle plate 81 is inserted into the groove 83. The size of the groove 83 is smaller than the canopy 103. In this design, by providing the groove 83 and inserting the toggle plate 81 into the groove 83, it is easy to toggle the canopy 103 as a whole by the toggle plate 81, thereby avoiding leakage of the bottom layer.

[0056] like Figure 5 As shown, preferably, the transfer mechanism 7 includes a transfer bin 71, a drawer plate 72 provided at the bottom of the transfer bin 71 for receiving the canopy 103, and a third power member 73 for driving the drawer plate 72 to move. With this design, the canopy 103 pushed out by the storage mechanism 4 is received by the drawer plate 72, and then the drawer plate 72 is driven to move under the action of the third power member 73. During the process of the drawer plate 72 being pulled out, the stacked canopies 103 are blocked by the transfer bin 71 and fall into the transfer bin 71, effectively preventing the subsequent canopy stacks from not being properly advanced into the transfer bin 71 and the bottom canopy 103 from being stuck in the transfer bin 71. When the drawer plate 72 is withdrawn, the entire stack of materials will be roughly sorted by the limit of the transfer bin 71.

[0057] like Figure 5As shown, preferably, the material shifting assembly 8 includes a shifting plate 81 disposed in the transfer bin 71 for shifting the canopy 103 into the silo 1 and a fourth power member 82 for driving the shifting plate 81 to move. With this design, by providing the shifting plate 81 and the fourth power member 82, after the canopy 103 in the silo 1 is completely taken out, the canopy 103 in the transfer bin 71 can be shifted into the silo 1, thereby ensuring continuous access to the canopy 103.

[0058] like Figure 3-4 As shown, in one embodiment, the pushing mechanism 5 includes:

[0059] The upper shifting assembly 51 is used to shift the upper portion of the entire stack of canopies 103 in the height direction, and includes a plurality of spaced upper shifting plates 511 for inserting between two adjacent stacks of canopies 103 and a first connecting plate 512 for mounting the upper shifting plates 511;

[0060] The lower shifting assembly 52 is used to shift the lower portion of the entire stack of canopies 103 in the height direction, and includes a plurality of spaced lower shifting plates 521 for inserting from the bottom between two adjacent stacks of canopies 103 and adapted to the upper shifting plate 511, and a second connecting plate 522 for mounting the lower shifting plates 521;

[0061] The power assembly 54 is used to drive the first connecting plate 512 and the second connecting plate 522 to move in the front-back direction simultaneously, so as to transport the entire stack of canopies 103 .

[0062] With this design, the upper shift plate 511 and the lower shift plate 521 are adapted to cover the height direction of the entire stack of canopies 103, so that when the power component 54 drives the first connecting plate 512 and the second connecting plate 522 to move in the front and rear directions, the upper shift plate 511 and the lower shift plate 521 can cooperate to drive the entire stack of canopies 103 to move, thereby pushing the canopy 103.

[0063] like Figure 3-4 As shown, in one embodiment, the device further includes an adjustment assembly 53 for simultaneously adjusting the positions of the first connecting plate 512 and the second connecting plate 522, and a second power member 534 for driving one of the first connecting plate 512 or the second connecting plate 522. In this design, by providing the adjustment assembly 53, the positions of the first connecting plate 512 and the second connecting plate 522 can be adjusted simultaneously, and by providing the second power member 534, one of the first connecting plate 512 or the second connecting plate 522 can be driven, thereby facilitating the simultaneous adjustment of the positions of the first connecting plate 512 and the second connecting plate 522.

[0064] like Figure 3-4As shown, in one embodiment, a column 513 is provided at the bottom of the first connecting plate 512, a linear bearing 523 is provided at the bottom of the second connecting plate 522, and the adjustment component 53 includes:

[0065] The base 531 is connected to the power assembly 54 and is used to install the linear bearing 523 and the second power member 534;

[0066] An adjustment plate 532 , used for mounting the column 513 and slidably disposed on the base 531 ;

[0067] a connecting member, comprising an inclined portion 533 provided on one of the adjusting plate 532 or the second connecting plate 522 and a roller 524 provided on the other of the adjusting plate 532 or the second connecting plate 522 , wherein the roller 524 is adapted to the inclined portion 533 ;

[0068] The reset member 536 is arranged perpendicular to the movement direction of the second power member 534 and is used to reset one of the first connecting plate 512 or the second connecting plate 522 that is not driven by the second power member 534. The reset member 536 is a spring.

[0069] With this design, by setting a base 531 connected to the power assembly 54, after the positions of the upper and lower plates 511 and 521 are adjusted, the power assembly 54 can be used to drive the entire stack of canopies 103 to move; by setting the adjustment plate 532 and the base 531, it is convenient to install the column 513 and the linear bearing 523; the second power member 534 drives the adjustment plate 532 (that is, drives the first connecting plate 512) or drives the second connecting plate 522. By setting the connecting member, it is convenient for the adjustment plate 532 and the second connecting plate 522 to move simultaneously. When the adjustment plate 532 moves, it drives the first connecting plate 512 to move, so that it is convenient for the second power member 534 to drive the first and second connecting plates 512 and 522 to move simultaneously, and by setting the reset member 536, during the reset process, the second power member 534 can drive one of the first and second connecting plates 512 and 522 to reset, and the other can be reset under the action of the reset member 536, which is convenient for the next transportation of the canopy 103.

[0070] like Figure 3-4 As shown, preferably, the base 531 is provided with a second guide rail 535 for sliding the adjustment plate 532. This design facilitates the sliding of the adjustment plate 532.

[0071] like Figure 3-4As shown, preferably, the power assembly 54 includes a support 541 arranged below the base 531 , and the support 541 is provided with a third guide rail 542 for the base 531 to move forward and backward and a fifth power member 543 for driving the base 531 .

[0072] With this design, by providing the fifth power member 543, it is possible to facilitate the movement of the base 531 in the front-rear direction, so that when the upper and lower plates 511 and 521 are inserted between two adjacent stacks of canopies 103, the entire stack of canopies 103 is driven forward by the fifth power member 543; and, after the entire stack of canopies 103 is moved, when the upper and lower plates 511 and 521 are retracted, the upper and lower plates 511 and 521 can be driven to reset by the fifth power member 543, thereby facilitating the pushing of subsequent canopies 103; by providing the support 541 and providing the third guide rail 542 on the support 541, the movement of the base 531 is facilitated.

[0073] The working principle of this embodiment is as follows: in the initial state, the upper dial plate 511 and the lower dial plate 521 are respectively located outside the canopy 103. When multiple canopies 103 are placed in the storage mechanism 4, the second power member 534 is opened, driving the adjustment plate 532 or the second connecting plate 522 to move. Under the cooperation of the inclined plate and the roller 524, the upper dial plate 511 and the lower dial plate 521 are respectively placed between the two canopies 103. The fifth power member 543 is opened, driving the upper dial plate 511 and the lower dial plate 521 to move. The shifting plate 521 pushes the canopy 103 forward a predetermined distance. At this time, the canopy 103 located in the front of the conveying direction moves onto the drawer plate 72. The second power member 534 is opened, driving the adjustment plate 532 or the second connecting plate 522 to move. With the cooperation of the inclined plate and the roller 524, the upper shifting plate 511 and the lower shifting plate 521 are respectively moved away from between the two stacks of canopies 103. The fifth power member 543 is opened, driving the upper shifting plate 511 and the lower shifting plate 521 to return to their starting state.

[0074] The third power member 73 drives the drawer plate 72 to move outward. Under the blocking effect of the transfer bin 71, the drawer plate 72 is pulled out, and the entire stack of canopies 103 falls into the transfer bin 71. Then, the fourth power member 82 drives the shifting plate 81 to move, shifting the canopies 103 into the interior of the silo 1.

[0075] The suction cup 21 takes out the lowest sky cover 103 from the discharge port 11 set at the bottom of the silo 1. At this time, the opening of the sky cover 103 faces upward, and the first power part is driven to open. The suction cup 21 follows the rotating shaft and the follower wheel 33 to move along the track groove 32. Under the action of the semicircular groove 322, the suction cup 21 rotates 180 degrees. At this time, the opening of the sky cover 103 faces downward, and then the sky cover 103 is added to the ground cover 101 and the combination 102 of the inner mold and the surrounding strip.

[0076] Combine Figure 1 and Figure 6 The utility model also provides an inner box machine forming mechanism, including:

[0077] The rotating table 6 includes a first station 62, a second station 63, a third station 64 and a fourth station 65 arranged in sequence along the rotating direction of the rotating table 6;

[0078] The first station 62 is used to add a ground cover 101 in the placement table 61;

[0079] The second workstation 63 is used to add the inner mold and the surrounding strip assembly 102 in the placement table 61 after the floor cover 101 is added;

[0080] The third station 64 is used to add the top cover 103 after adding the combination 102 of the inner mold and the surrounding strip. The third station 64 uses the top cover feeding mechanism of the inner box machine mentioned above for loading.

[0081] The fourth workstation 65 is used to output the box blank 104 after the top cover 103, the combination 102 of the inner mold and the surrounding strip, and the bottom cover 101 are assembled.

[0082] This design can facilitate the rapid assembly of the cover 101, the inner mold and the surrounding strip assembly 102, and the top cover 103 into the box blank 104. The assembly efficiency is improved by providing the rotating table 6 and multiple workstations.

[0083] It should be noted that the first power member, the second power member 534 , the third power member 73 , the fourth power member 82 , and the fifth power member 543 include but are not limited to cylinders, hydraulic cylinders, or electric push rods.

[0084] Example 2:

[0085] See also Figure 7 The difference between this embodiment and embodiment 1 is that the flipping mechanism 3 includes a rotary driver for driving the two stealing mechanisms 2 to rotate, and the stealing mechanism 2 includes a cylinder for driving the suction cup 21 to move in the vertical direction.

[0086] Such design, by setting up a rotary drive, can facilitate driving the stealing mechanism 2 to rotate, realize the change of the posture of the sky cover 103. When in use, the cylinder in the upper stealing mechanism 2 drives the suction cup 21 to move upward, and the suction cup 21 adsorbs the sky cover 103 at the bottom of the silo 1, and then the cylinder drives the suction cup 21 to move downward, and the rotary drive drives the stealing mechanism 2 to rotate, and the upper and lower stealing mechanisms 2 interchange positions. The upper stealing mechanism 2 repeats the above operation to take the sky cover 103 from the silo 1, and the cylinder of the lower stealing mechanism 2 drives the suction cup 21 to move downward until the adsorbed sky cover 103 falls on the ground cover 101 and the combination 102 of the inner mold and the surrounding strips, and then the cylinder drives the suction cup 21 to move upward, and the rotary drive rotates to continue to interchange the upper and lower stealing mechanisms 2.

[0087] This embodiment can still achieve the purpose of the utility model, and its development cost is relatively low.

[0088] Example 3:

[0089] The difference between this embodiment and embodiment 1 is that the adjustment component 53 is not provided, and the upper shifting component 51 has a telescopic movable stroke in the left and right directions. Figure 4 The content can be understood that the lower shifting assembly 52 has a telescopic movable stroke in the vertical direction, and is provided with a cylinder for driving the second connecting plate 522 to move in the vertical direction and a cylinder for driving the first connecting plate 512 to move in the left and right directions.

[0090] With this design, the second connecting plate 522 is driven by the cylinder to move in the vertical direction, thereby facilitating the lower shifting plate 521 to be inserted or retracted between two adjacent stacks of canopies 103; the first connecting plate 512 is driven by the cylinder to move in the left and right directions, thereby facilitating the upper shifting plate 511 to be inserted or retracted between two adjacent stacks of canopies 103.

[0091] Preferably, the air cylinder in the above content can be equivalently replaced by a hydraulic cylinder or an electric push rod.

[0092] This embodiment can still achieve the purpose of the utility model. The upper shifting assembly 51 and the lower shifting assembly 52 are driven independently to achieve cutting in the height direction of the material stack, and the development cost is low.

[0093] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0094] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0095] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
