[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] It should be noted that, in this embodiment, for the convenience of describing the specific solution, Figure 1 The directions shown in the figure are defined as horizontal, longitudinal and vertical respectively. Such definitions are only for the convenience of explaining the specific scheme and do not constitute any substantial limitation.

[0022] Reference below Figure 1-Figure 8 The present invention describes a conveying mechanism for packaged items and a packaging device, as well as a working method thereof, according to an embodiment of the present application.

[0023] Reference Figure 1-8The packaging device described in the embodiment of the present application includes a conveying mechanism 100 and a pressing mechanism 200; the conveying mechanism 100 for the items to be packaged includes a first support frame 110, a second support frame 120, a transmission member 130 and a bearing member 140; wherein the first support frame 110 is used to receive the items to be packaged for front and rear conveyance; the second support frame 120 is laterally arranged on one side of the first support frame 110; the transmission member 130 is arranged at the first support frame 110, and the transmission member 130 can convey the items to be packaged at the top of the first support frame 110 to the second support frame 120; the bearing member 140 is arranged at the top of the second support frame 120.

[0024] In the above technical solution, the supporting member 140 includes a first supporting plate 141 and a second supporting plate 142; the first supporting plate 141 is longitudinally slidably arranged at the top end of the second supporting frame 120; the second supporting plate 142 is arranged at the bottom end of the first supporting plate 141, and the second supporting plate 142 is vertically slidably arranged at one side of the second supporting frame 120.

[0025] By setting up the above technical scheme, the plastic packaging bag to be pressed is placed on the top of the first support frame 110, and then pressed by the pressing mechanism 200; the pressed pieces to be packaged are moved from the top of the first support frame 110 to the first supporting plate 141 at the top of the second support frame 120 via the transmission of the conveyor 130, and then released from the first supporting plate 141 to the top of the second supporting plate 142; with the transmission of the conveyor 130, multiple pieces to be packaged are successively moved to the first supporting plate 141 and released to the top of the second supporting plate 142, and the second supporting plate 142 moves vertically along the second support frame 120, so as to realize the multi-layer stacking and conveying of the pieces to be packaged at the top of the second supporting plate 142.

[0026] In a specific technical solution, the top of the first support frame 110 has a support surface, which is used to support the plastic packaging bag for pressing the plastic packaging bag, and a transmission channel 111 is opened on the support surface; the transmission member includes a transmission belt 131 arranged at the bottom end of the first support frame 110 and a transmission rod 132 arranged on the outside of the transmission belt 131; the transmission rod 132 used to transmit the packaged items can be arranged through the transmission channel 111.

[0027] That is, in this technical solution, after the plastic packaging bag is pressed, the transmission rod 132 passing through the transmission channel 111 can drive the movement of the pressing part under the transmission of the transmission belt 131, so as to achieve the effect of moving the packaged item from the top of the first support frame 110 to the top of the second support frame 120.

[0028] It is understandable that a plurality of transmission rods 132 may be disposed on the outer side of the same transmission belt 131 , and the transmission belt 131 may be driven by a stepping motor or a conventional driving motor.

[0029] In a preferred embodiment described in the present application, an avoidance channel is provided through the second supporting plate 142, and the supporting member 140 further includes a supporting block 143 and a supporting roller 144, wherein the supporting block 143 is embedded in the avoidance channel on both sides of the second supporting plate 142; the supporting roller 144 is embedded in the second supporting plate 142, and both ends of the supporting roller 144 are restricted by the corresponding supporting block 143; and the bottom end portion of the supporting roller 144 extends out of the avoidance channel of the second supporting plate 142.

[0030] In this technical solution, the carrying roller 144 can rotate relative to the second carrying plate 142, so that when a certain number of items to be packaged are stacked on the second carrying plate 142 and need to be manually transferred, the items to be packaged that are stacked in multiple layers can be conveniently transferred; At the same time, both ends of the supporting roller 144 are provided with limiting grooves 1441 / limiting blocks; the top of the supporting block 143 is provided with a limiting block 1431 / limiting groove corresponding to the limiting groove 1441 / limiting block; the limiting block 1431 can be clamped in the corresponding limiting groove 1441; that is, under normal working conditions, the supporting block 143 can limit the rotation of the supporting roller 144, so that the second supporting plate 142 can conveniently carry the package to be transferred; when the package to be transferred needs to be transferred, it is only necessary to release the restriction of the supporting block 143 on the supporting roller 144.

[0031] Based on the above description, in order to facilitate the removal of the restriction of the supporting block 143 on the supporting roller 144, in a specific embodiment of the present application, the supporting member 140 also includes a supporting plate 145 arranged at the bottom end of the second support frame 120; wherein, the second supporting plate 142 can slide along the second support frame 120 to the supporting plate 145 so that the supporting roller 144 extending out of the second supporting plate 142 is in contact with the supporting plate 145.

[0032] During operation, as the number of items to be packaged on the second carrier plate 142 gradually increases, the second carrier plate 142 gradually moves downward until the carrier roller 144 extending out of the second carrier plate 142 partially abuts against the supporting plate 145, and the supporting plate 145 is supported on the carrier roller 144. At this time, under the dead weight of the second carrier plate 142 and the carrier block 143, the carrier block 143 is separated from the corresponding carrier roller 144, so that the limiting groove 1441 releases the restriction on the limiting block 1431, and the carrier roller 144 can rotate relative to the second carrier plate 142, thereby facilitating the transfer of items to be packaged on the second carrier plate 142.

[0033] In another technical solution, a roller 1451 is further provided on the supporting plate 145 to further reduce the friction between the supporting plate 145 and the carrying roller 144 .

[0034] In a specific technical solution of the present application, a receiving surface 1411 is provided on one side of the first supporting plate 141 , and the receiving surface 1411 is provided at a preset angle to the bottom surface of the first supporting plate 141 ; a first elastic member 1412 is provided on one side of the first supporting plate 141 .

[0035] In this technical solution, the first supporting plate 141 can receive the items to be packaged that are conveyed from the first supporting frame 110. The gravity of the items to be packaged acts on the receiving surface 1411, allowing the first receiving surface 1411 to move longitudinally along the first supporting frame 110. The moving first supporting plate 141 compresses the first elastic member 1412 until the items to be packaged are released above the second supporting plate 142. Subsequently, under the action of the first elastic member 1412, the first supporting plate 141 returns to a receiving state, thereby facilitating the reception of the next item to be packaged.

[0036] In a better technical solution, two first supporting plates 141 are provided, and the two first supporting plates 141 are arranged opposite to each other. In this case, the receiving surface 1411 is arranged on the side where the two first supporting plates 141 are close to each other, and the first elastic member 1412 is arranged on the side where the two first supporting plates 141 are away from each other.

[0037] In another embodiment, a roller 1414 is rotatably provided at the top end of the first carrying plate 141 . The provision of the roller 1414 facilitates the conveying member 130 to push the packaged items to the top end of the first carrying plate 141 .

[0038] From the above explanation, it can be known that in the technical scheme of the present application, as the number of items to be packaged carried on the top of the second supporting plate 142 increases, the second supporting plate 142 is gradually moved downward. Therefore, in a specific technical scheme of the present application, the aforementioned conveying mechanism 100 for items to be packaged also includes a moving member 150 for driving the second supporting plate 142 to move vertically along the second support frame 120; wherein the moving member 150 includes a first driving rod 151 and a sliding sleeve 152: wherein the first driving rod 151 is configured on one side of the second support frame 120; the sliding sleeve 152 is arranged on the outer side corresponding to the first driving rod 151, and the sliding sleeve 152 is connected to one side of the second supporting plate 142.

[0039] In this solution, the sliding sleeve 152 can drive the second carrying plate 142 to move along the outer side of the first driving rod 151, so that the second carrying plate 142 gradually moves downward as the number of items to be packaged at the top of the second carrying plate 142 increases.

[0040] In the above scheme, the movement of the sleeve 152 can use an external linear mechanism, such as a linear guide, a pneumatic rod, a hydraulic rod, etc.; in another technical scheme, the first driving rod 151 is rotatably configured on one side of the second support frame 120, and when the first driving rod 151 rotates in the working state, it can drive the sleeve 152 to move; the moving part 150 also includes a synchronous belt 153 arranged on one side of the second support frame 120, and the synchronous belt 153 is sleeved on one end of the first driving rod 151 on the corresponding side, and a synchronous block 1531 is connected to the outer side of the synchronous belt 153; the synchronous block 1531 is driven by a second driving rod 156 so that the synchronous belt 153 drives the corresponding moving part 150 to rotate.

[0041] In this solution, the movement of the sliding sleeve 152 and the second carrying plate 142 along the second support frame 120 is achieved by the rotation of the first driving rod 151, and the rotation of the first driving rod 151 is based on the transmission of the synchronous belt 153, and the synchronous belt 153 is driven by a second driving rod 156. Therefore, in order to enable the second carrying plate 142 to move a predetermined distance after carrying a package on its top, it is necessary to ensure the synchronization of the rotation of the first driving rod 151 and the transmission of the conveyor.

[0042] Based on the above description, the transmission power of the conveying member comes from a conveying motor 133. In a specific scheme of the present application, the conveying motor 133 synchronously drives a reciprocating rod 154, and the reciprocating rod 154 is rotatably arranged on one side of the second support frame 120; specifically, the reciprocating rod 154 can be driven by a worm gear assembly arranged on one side of the transmission belt 131, so that the reciprocating rod 154 is synchronized with the transmission belt 131; a moving block 155 is arranged on the outer side of the reciprocating rod 154, and the moving block 155 is arranged on one side of the second support frame 120 along a transverse sliding direction, and the second driving rod 156 is connected to one side of the moving block 155 through a second elastic member 1561.

[0043] That is, in the above technical solution, the conveying motor 133, on the one hand, drives the transmission belt 131 to convey the items to be packaged, and on the other hand, can drive the moving block 155 to move back and forth laterally along the second support frame 120 through the reciprocating rod 154, so as to realize intermittent shifting of the synchronous belt 153, so that when one of the items to be packaged moves to the top of the second supporting plate 142, the second supporting plate 142 can move downward a predetermined distance driven by the first driving rod 151 and the sliding sleeve 152.

[0044] It is understandable that some plastic packaging bags are relatively light in weight. After the pressed plastic packaging bags are transferred from the conveyor 130 to the second support frame 120, it is difficult to move the first supporting plate 141 along the longitudinal direction of the second support frame 120 relying on the weight of the packaging bags themselves. Therefore, in a specific scheme of the present application, a connecting plate 1413 is provided on the side of the first supporting plate 141 away from the receiving surface 1411, and the moving member 150 also includes a driving block 157, which is connected to one side of the connecting plate 1413.

[0045] Based on the above explanation, while the transmission belt 131 transmits the items to be packaged, the reciprocating rod 154 can drive the moving block 155 and the second driving rod 156 arranged at the top of the moving block 155 to move, so that the second driving rod 156 drives the synchronization block 1531 to move; through the setting of the driving block 157, the second driving rod 156 can also push the driving block 157 and then drive the first supporting plate 141 to move through the connecting plate 1413, so that the items to be packaged carried on the top of the first supporting plate 141 are released at the top of the second supporting plate 142.

[0046] In another technical solution, a fixed block is connected to the top of the moving block 155, and the second driving rod 156 is connected to one side of the fixed block through the second elastic member 1561, so that when the moving block 155 slides toward the side away from the first support frame 110, the second driving rod 156 abuts against the fixed block, so that the second driving rod 156 can abut against the driving block 157 and the synchronous block 1531; when the moving block 155 moves toward the side close to the first support frame 110, the second driving rod 156 automatically rotates to make way due to the resistance of the synchronous block 1531 and the driving block 157, thereby avoiding the reverse rotation of the synchronous belt 153 during reverse movement and avoiding motion interference with the driving block 157.

[0047] In the above scheme, the first driving rod 151 is a threaded rod, and the corresponding sliding sleeve 152 is threadedly arranged on the outer side of the first driving rod 151. When the first driving rod 151 rotates, it can drive the sliding sleeve 152 and the second supporting plate 142 to move vertically along the second support frame 120.

[0048] Among them, the first driving rod 151 can be two groups arranged at the four corners of the second support frame 120, and the outer side of each group of first driving rods 151 is sleeved with the same synchronous belt 153; the two synchronous belts 153 are driven by the same transmission motor 133, ensuring that the second supporting plate 142 can move stably along the second support frame 120 during operation.

[0049] In a more preferred solution, the sliding sleeve 152 includes a fixed sleeve 1521, a pushing hole 15211 larger than the outer diameter of the first driving rod 151 is formed on the fixed sleeve 1521, a limiting plate 1522 is slidably connected inside the fixed sleeve 1521, one side of the limiting plate 1522 is elastically connected to the fixed sleeve 1521 through a third elastic member 1523, and the other side of the limiting plate 1522 is provided with a threaded groove 15221 adapted to the first driving rod 151.

[0050] In the above technical solution, the third elastic member 1523 drives the limiting plate 1522 to abut against the first driving rod 151. When the first driving rod 151 rotates, it cooperates with the limiting plate 1522 and the fixing sleeve 1521 to drive the second supporting plate 142 to descend. When the limiting plate 1522 is not abutted against the first driving rod 151, the second supporting plate 142 can be separated from the restriction of the first driving rod 151 to quickly adjust the height.

[0051] The two adjacent limiting plates 1522 are connected and fixed by a flexible connecting strip 158, and a push rod 159 is rotatably connected to one side of the second bearing plate 142. One end of the push rod 159 can slide in contact with the flexible connecting strip 158. When the push rod 159 rotates downward to drive the flexible connecting strip 158 to deform, the flexible connecting strip 158 drives the limiting plate 1522 to compress the third elastic member 1523 to move, so that the limiting plate 1522 is no longer in contact with the first driving rod 151. At this time, the second bearing plate 142 can be quickly driven to slide up and down to adjust its height position. Although the preferred embodiments of the present application have been described, once the technical personnel in this field know the basic creative concept, they can make additional changes and modifications to these embodiments. Therefore, the attached claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0052] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
