[0002] In existing technologies, plastic container surface printing machines often use manual box collection at the box collection station. Manual operation cannot achieve continuous production, especially when processing large batches of products, where the efficiency problem becomes more obvious. In addition, manual box collection is slow and cannot keep up with the production speed of the printing machine, which can easily lead to the accumulation of printed containers inside the machine and cause downtime. Furthermore, manual box collection requires a large amount of manpower, increasing the company's operating costs. Utility Model Content

[0038] refer to Figures 1 to 7 , Figure 1 This is a general perspective view of the flipping and collecting mechanism 1 of a printing machine for the surface of a square box 2 plastic container provided in an embodiment of the present invention; Figure 2 This diagram shows a partial structural schematic of the flipping and collecting mechanism 1 of a printing machine for the surface of a square box 2 plastic container provided in an embodiment of the present invention; Figure 3 This invention provides a perspective view of the feeding platform 10 in the flipping and collecting mechanism 1 of a plastic container surface printing machine for square boxes 2, according to an embodiment of the present invention. Figure 4 This illustration shows a partial structural diagram of the feeding platform 10 in the flipping and collecting mechanism 1 of a square box 2 plastic container surface printing machine provided in an embodiment of the present invention.

[0039] Figure 5 This invention provides a perspective view of the receiving platform 15 in the flipping and receiving mechanism 1 of a square box 2 plastic container surface printing machine according to an embodiment of the present invention. Figure 6 A perspective view of the flipping platform 17 in the flipping and collecting mechanism 1 of a square box 2 plastic container surface printing machine provided in an embodiment of the present invention is shown; Figure 7 This illustration shows a partial structural diagram of the moving feeding device 16 in the flipping and collecting mechanism 1 of a square box 2 plastic container surface printing machine provided in an embodiment of the present invention.

[0040] like Figures 1 to 7As shown, a flipping and collecting mechanism 1 of a printing machine for the surface of a square box 2 plastic container includes a feeding platform 10 and a collecting platform 15, wherein:

[0041] The feeding platform 10 and the receiving platform 15 are along the first direction ( Figure 2 The feeding platform 10 is spaced apart in the middle X direction. It includes a feeding bin 100 and a discharging mechanism 11. The feeding bin 100 is arranged along the second direction (as shown in the X direction). Figure 2 Extending in the Z direction, the top is provided with a feeding end 101 for stacking and storing multiple square boxes 2 along the second direction. The discharging mechanism 11 is located at the bottom of the feeding bin 100 and is used to push the square boxes 2 to be transferred at the bottom of the feeding bin 100 towards the receiving platform 15 along the first direction.

[0042] The receiving platform 15 includes a mobile feeding device 16, a tilting platform 17, and a receiving bin 18. The mobile feeding device 16 and the receiving bin 18 are aligned along a third direction. Figure 2 (As shown in the Y direction) are arranged sequentially. The tilting platform 17 is located on top of the mobile feeding device 16 and is used to switch between the receiving position and the feeding position via the mobile feeding device 16. The receiving position includes the tilting platform 17 moving to the end of the mobile feeding device 16 facing the feeding platform 10 in the first direction. The feeding position includes the tilting platform 17 moving to a position corresponding to the receiving bin 18 in the third direction.

[0043] The flipping platform 17 includes a loading flap 170 and a drive device 173. When the flipping platform 17 is in the receiving position, the drive device 173 drives the loading flap 170 to flip, so that the bottom of the loading flap 170 corresponds to the discharge mechanism 11 along a first direction, for receiving the box 2 to be transferred. When the flipping platform 17 is not in the receiving position, the drive device 173 drives the loading flap 170 to flip by a set angle along the first direction away from the receiving platform 15. The first direction, the second direction, and the third direction are perpendicular to each other.

[0044] This application provides a flipping and collecting mechanism 1 for a plastic container surface printing machine (square box 2). The feeding hopper 100 stacks and stores multiple square boxes 2 along a second direction, fully utilizing vertical space and increasing storage capacity. The discharging mechanism 11, located at the bottom of the feeding hopper 100, can push the square boxes 2 to be transferred along a first direction, ensuring stable discharge of the square boxes 2. The flipping platform 17 not only flips the square boxes 2 but also switches between a receiving position and a feeding position via a moving feeding device 16. When the flipping platform 17 is in the receiving position, the drive device 173 drives the loading flap 170 to flip, so that the bottom of the loading flap 170 corresponds to the discharging mechanism 11 along the first direction, accurately receiving the square boxes 2 to be transferred, and then transferring them to the feeding position for unloading. The entire flipping and collecting process is automated, requiring no manual intervention from feeding, flipping to collecting, which not only improves production efficiency but also reduces errors that may be caused by manual operation.

[0045] In some embodiments, reference Figures 1 to 7 The moving feeding device 16 moves along the fourth direction ( Figure 2 The fourth direction (as shown in the E direction) is inclined, with the fourth direction inclined at a 45° angle to both the first and second directions, and perpendicular to the third direction. The moving feeding device 16 includes a drive cylinder 160, multiple guide rods 161, a moving block 162, a protective housing 163, and a support base 164. The moving block 162 and each guide rod 161 extend along the fourth direction. The multiple guide rods 161 are spaced apart along the third and second directions. The moving block 162 is slidably connected to the guide rods 161. The drive cylinder 160 is located at one end of the multiple guide rods 161 in the first direction near the discharge mechanism 11 and is drively connected to the moving block 162, used to drive the moving block 162 to move relative to the discharge mechanism 11 along the fourth direction. The protective housing 163 covers the drive cylinder 160, and the support base 164 extends along the second direction and is spaced apart along the first direction at the bottom of the protective housing 163.

[0046] For example, the guide rod 161 extends along the fourth direction, and the moving block 162 is slidably connected to the guide rod 161. This structure can ensure the high precision and stability of the moving block 162 during movement, and can effectively reduce friction and improve the smoothness of the movement of the material-carrying flap 170.

[0047] In some embodiments, reference Figures 1 to 7The loading tipper 170 includes a first side plate 171 and a second side plate 172. The driving device 173 includes a connecting rod 174, a connecting shaft 175, a hydraulic telescopic rod 176, and an adapter 177. The first side plate 171 extends along a first direction, and the second side plate 172 extends along a second direction. The bottom of the second side plate 172 is connected to the end of the first side plate 171 away from the feeding platform 10 along the first direction. A fixing block 179 is provided on the side of the second side plate 172 away from the feeding platform 10 along the first direction. The fixing blocks 179 are located near the bottom of the second side plate 172 and are spaced apart along a third direction. The connecting shaft 175 extends along a third direction, and both ends are connected to the fixing blocks 179.

[0048] Connecting rods 174 are arranged parallel above the drive cylinder 160 and spaced apart along a third direction. One end of the connecting rod 174 along the first direction is connected to the moving block 162, and the other end is rotatably connected to the connecting shaft 175. An adapter 177 is sleeved on the connecting shaft 175 and positioned between the two connecting rods 174. The adapter 177 has an extension 178 on the side away from the second side plate 172 along the second direction. One end of a hydraulic telescopic rod 176 is connected to the moving block 162, and the other end is rotatably connected to the extension 178. The extension 176 expands, causing the extension 178 to move, thereby driving the connecting shaft 175 to rotate relative to the connecting rods 174, causing the second side plate 172 to rotate parallel to the guide rod 161.

[0049] For example, the first side plate 171 and the second side plate 172 are connected at right angles, allowing the material-carrying tilting plate 170 to better adapt to movement requirements in different directions, while providing a more stable load-bearing capacity. The hydraulic telescopic rod 176 is used to drive the tilting plate 170 to flip. It achieves telescopic movement through hydraulic principles, providing a large driving force while ensuring smooth movement without transmission backlash. Furthermore, the hydraulic telescopic rod 176 can also achieve a self-locking function, ensuring the stability of the tilting plate in a specific position. Further, the top of the protective housing 163 has clearance areas 167 at both ends along a third direction, corresponding to the fixing block 179, for allowing the material-carrying tilting plate 170 to move along a fourth direction. The drive cylinder 160 has a bottom baffle 168 on the side facing the discharge mechanism 11 along a first direction. The bottom baffle 168 extends along a second direction and is used to abut and limit the tilting plate 170 when it rotates to the receiving position corresponding to the discharge mechanism 11.

[0050] In some embodiments, reference Figures 1 to 7The mobile feeding device 16 also includes a pushing device 19. A receiving bin 18 extends along a fourth direction and is located near the end of the protective housing 163 away from the feeding platform 10 along a first direction. The receiving bin 18 is connected to the protective housing 163 on one side along a third direction, and baffles 180 are provided on the other side and on one side along the fourth direction. A support base 164 is provided at the bottom of the receiving bin 18. The pushing device 19 is located on the side of the protective housing 163 opposite to the receiving bin 18 along a third direction, and includes a pushing cylinder 190 and a pushing block 191. The pushing cylinder 190 extends along a third direction, with its drive end facing the receiving bin 18. The pushing block 191 extends along a fourth direction and is connected to the drive end of the pushing cylinder 190, used by the pushing cylinder 190 to drive the pushing block 191 to push the transfer box 2 located in the loading flap 170 into the receiving bin 18.

[0051] For example, the receiving bin 18 extends along the fourth direction and is located near the end of the protective housing 163, making the overall structure of the device more compact and reducing the floor space. Baffles 180 are provided on both sides and one side along the fourth direction of the receiving bin 18, and a support base 164 is provided at the bottom. The baffles 180 effectively prevent materials from falling during conveying, while the support base 164 improves the stability of the receiving bin 18. Furthermore, driven by the pushing cylinder 190, the pushing block 191 can automatically complete the pushing action, pushing the square box 2 from the loading flap 170 into the receiving bin 18, reducing manual intervention and improving production efficiency.

[0052] In some embodiments, reference Figures 1 to 7 The feeding platform 10 also includes a left fixed plate 107, a right fixed plate 108, and a lifting assembly 12. The left fixed plate 107 and the right fixed plate 108 are arranged parallel to each other along a second direction, and an installation section 109 is symmetrically arranged inside them along a third direction. The feeding bin 100 is located between the left fixed plate 107 and the right fixed plate 108. The lifting assembly 12 is respectively located on opposite sides of the left fixed plate 107 and the right fixed plate 108 along a third direction, and includes a drive motor 120, a linkage rod 121, a first synchronous pulley mechanism 122, and a second synchronous pulley mechanism 123. The linkage rod 121 extends along a first direction and is located above the installation section 109. The drive motor 120 is located near the bottom of the installation section 109 and is arranged corresponding to the linkage rod 121 along the second direction. The first synchronous pulley mechanism 122 and the second synchronous pulley mechanism 123 are arranged sequentially along the first direction, and both ends along the second direction are respectively connected to the output shaft of the drive motor 120 and the linkage rod 121.

[0053] For example, through the cooperation of the drive motor 120 and the synchronous pulley mechanism, the feeding platform 10 can achieve automated lifting, reducing manual operation, improving work efficiency, and also reducing the risk caused by human error. The first synchronous pulley mechanism 122 and the second synchronous pulley mechanism 123 are arranged sequentially along the first direction to ensure the stability of the lifting process, effectively reducing swaying during lifting and improving equipment safety. Furthermore, the bottom of the feeding platform 10 is also provided with a base 169 for supporting the left fixed plate 107, the right fixed plate 108, the drive motor 120, and the moving feeding device 16.

[0054] In some embodiments, reference Figures 1 to 7 The feeding platform 10 also includes a fork transfer assembly 14, which is respectively disposed on opposite sides of the left fixed plate 107 and the right fixed plate 108 along a third direction. The fork transfer assembly 14 includes an upper fork 140, a lower fork 141, and a linear guide rail 142. The linear guide rail 142 extends along a second direction and is respectively disposed on both sides of the installation interval 109 along a first direction. The upper fork 140 and the lower fork 141 are spaced apart along the second direction. The upper fork 140 includes an upper bearing block 143, both ends of which are slidably connected to the linear guide rail 142 on one side along the third direction, and the other side passes through the installation interval 109 and is connected to the first synchronous pulley mechanism 122. The lower fork 141 includes a lower bearing block 144, both ends of which are slidably connected to the linear guide rail 142 on one side along the third direction, and the other side passes through the installation interval 109 and is connected to the second synchronous pulley mechanism 123.

[0055] For example, there is a pair of upper and lower forks 141 on the left and right sides. The upper fork 140 moves synchronously through the first synchronous pulley mechanism 122, and the lower fork 141 moves synchronously through the second synchronous pulley mechanism 123. The lower fork 141 is used to transfer the stacked boxes 2 to the transition platform 110. The main function of the upper fork 140 combination is to assist in collecting the continuous boxes 2 above during the downward feeding process of the lower fork 141, and then hand them over to the lower fork 141 to achieve continuous cyclic box collection.

[0056] In some embodiments, reference Figures 1 to 7 Both the loading fork 140 and the unloading fork 141 include a telescopic assembly 145. The telescopic assembly 145 includes a telescopic cylinder 146, a connecting plate 147, and fork plates 148. The telescopic cylinder 146 is respectively located at the top of the upper support block 143 and the bottom of the lower support block 144. The telescopic drive end of the telescopic cylinder 146 is positioned facing the feed hopper 100 along the second direction and can telescopically move along the second direction. The connecting plate 147 is connected to the telescopic drive end on one side along the second direction, and the fork plates 148 are spaced apart on the other side along the first direction. The fork plates 148 extend along the third direction and are inclined upwards at their bottom along the second direction.

[0057] For example, the telescopic assembly 145 uses a telescopic cylinder 146 as a power source, enabling precise telescopic movement along the second direction. This ensures that the fork plate 148 can accurately reach the designated position, thereby improving the accuracy of feeding, automating the telescopic action, reducing manual operation, and improving work efficiency. The bottom of the fork plate 148 is inclined upwards along the second direction. This inclined design can better adapt to the shape of the material, prevent the material from slipping during handling, and improve the stability of handling.

[0058] In some embodiments, reference Figures 1 to 7 The discharge mechanism 11 includes a transition platform 110, a linear motor 111, and a pusher block 112. The transition platform 110 extends along a first direction and is located at the bottom of the feeding hopper 100, used to support the box 2 to be transferred. An installation channel 113 extending along the first direction is provided at the center of the transition platform 110, and the linear motor 111 extends along the first direction and is located within the installation channel 113. The bottom of the pusher block 112 is correspondingly positioned along a third direction to the transition platform 110 and is connected to the mover of the linear motor 111, used to drive the pusher block 112 via the linear motor 111 to push the box 2 to be transferred along the first direction into the loading flap 170.

[0059] For example, the linear motor 111 directly drives the pusher block 112, reducing the number of transmission components and lowering the complexity and failure rate of the equipment. In addition, the linear motor 111 can provide greater thrust, enabling higher speeds and accelerations, ensuring the stability of the pusher block 112 when pushing a large number of stacked cubes 2.

[0060] In some embodiments, reference Figures 1 to 7 The feeding bin 100 includes a fixed plate 102, a left baffle 103, a right baffle 104, a front baffle 105, and a rear baffle 106. The fixed plate 102 is respectively disposed on both sides of the feeding bin 100 along a first direction, and its two ends along a third direction are respectively connected to the left fixed plate 107 and the right fixed plate 108. The left baffle 103 and the right baffle 104 both extend along a second direction. The left baffle 103 and the left fixed plate 107 are spaced apart along a third direction, and the right baffle 104 and the right fixed plate 108 are spaced apart along a third direction, and each has a moving range corresponding to the fork transfer assembly 14. The two ends of the left baffle 103 and the right baffle 104 along the first direction are connected to the fixed plate 102. The front baffle 105 and the rear baffle 106 are spaced apart along the first direction and connected to the fixed plate 102 along opposite sides of the first direction. The tops of the front baffle 105 and the rear baffle 106 are both bent toward opposite sides along the first direction to form the feed end 101.

[0061] For example, the front baffle 105 and the rear baffle 106 are spaced apart along the first direction, and their tops are bent towards opposite sides along the first direction to form the feed end 101. This design can better guide materials into the feed hopper 100, reduce material accumulation at the feed inlet, and improve feeding efficiency. The design of the feed hopper 100 can adapt to materials of different sizes by adjusting the spacing between multiple baffles, and has good versatility. The two ends of the square box 2 are supported by two feeding forks 140 or two discharging forks 141 corresponding to the third direction. The fork plate 148 in the telescopic assembly 145 enters the feed hopper 100 through the moving section and abuts against the edge of the square box 2 to support the entire square box 2. When the fork plate 148 exits from the feed hopper 100, the multiple square boxes 2 supported above fall freely, changing from being supported by the feeding fork 140 to being supported by the discharging fork 141, or changing from being supported by the discharging fork 141 to being supported by the transition platform 110.

[0062] Furthermore, counting sensors 114 are provided on the top of the front baffle 105 and the rear baffle 106, as well as on the top of the transition platform 110, for counting and controlling the number of collected square boxes 2.

[0063] In some embodiments, reference Figures 1 to 7 The feeding platform 10 also includes a brush acceleration mechanism 115 and an air blowing pipe 119. The brush acceleration mechanism 115 is located above the feeding end 101 and includes a connecting housing 116, a brush synchronous pulley mechanism 117, and a drive motor 118. The brush synchronous pulley mechanism 117 extends along a first direction, and the drive motor 118 is located on one side of the brush synchronous pulley mechanism 117 along a third direction, used to drive the brush synchronous pulley mechanism 117 to quickly move the square box 2 to the feeding end 101 of the feeding bin 100 by rubbing the surface of the square box 2. The connecting housing 116 covers the brush synchronous pulley mechanism 117 and the drive motor 118 and is connected to the left fixed plate 107. The air blowing pipe 119 is located on top of the connecting housing 116 and above the feeding end 101. The air blowing direction of the air blowing pipe 119 is towards the inside of the feeding bin 100, used to assist in accelerating the falling of the square box 2 to achieve rapid stacking and fitting.

[0064] For example, the brush acceleration mechanism 115 can adapt to square boxes 2 of different sizes, drive the brush to rotate and rub against the surface of the square box 2, so that the square box 2 is quickly transmitted to the feeding end 101 of the feeding bin 100, and cooperate with the air blowing pipe 119 to achieve a dual acceleration function, which significantly improves the feeding speed and stacking efficiency of the square box 2, thereby improving the production efficiency of the entire feeding platform 10.

[0065] In some embodiments, reference Figures 1 to 7The mobile feeding device 16 also includes a surrounding plate 165 and a connecting member 166. The surrounding plate 165 extends along the fourth direction and is located above the pushing device 19. It is respectively disposed on both sides of the protective housing 163 along the third direction at positions not corresponding to the receiving bin 18, and is used to cooperate in blocking when the loading flap 170 moves. The connecting member 166 is disposed on the side of the surrounding plate 165 away from the protective housing 163 along the third direction, and is spaced apart along the fourth direction. Its two ends are respectively connected to the side walls of the surrounding plate 165 and the protective housing 163.

[0066] For example, by setting up a partition 165 to shield the material-carrying flap 170, any material falling during movement is prevented, ensuring the stability of the box 2 during transportation. The connector 166 is connected at both ends to the side walls of the partition 165 and the protective shell 163, respectively, to prevent the partition 165 from shifting or deforming during use.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
