Description

Technical Field

[0001] This utility model belongs to the technical field of wine box packaging lid card transfer equipment, and relates to the feeding end pressing mechanism for a wine box packaging lid card feeding device. Background Technology

[0002] In the process of preparing the box lid cardboard for wine packaging, the box lid cardboard needs to be coated with glue and bonded to the cardboard shell to form the box lid. In the process, multiple sheets of packaging paper need to be bonded together to form the packaging box. Before coating the box lid cardboard with glue, it needs to be fed. An adsorption structure is used for adsorption and feeding. Before adsorption, in order to ensure adsorption stability, the stacked box lid cards need to be pressed tightly. If a direct drive mechanism is used for pressing, a separate power source is required, which is costly. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a feeding end clamping mechanism for a paper feeding device for wine box packaging lids, which does not require a power source, clamps under spring force, and automatically opens mechanically when needed, thereby reducing costs.

[0004] The technical solution adopted by this utility model is as follows: a pressing mechanism for the feeding end of a paper feeding device for wine box packaging lids includes a vertical cantilever rod set on the feeding side of the bottom of the pressing plate, a roller rotatably connected to the end of the vertical cantilever rod, the roller being able to touch a horizontal cantilever rod, the horizontal cantilever rod being connected to the horizontal arm of a V-shaped bending swing arm, the corner of the bending swing arm being rotatably connected to a mounting plate set at the bottom of the cylinder seat frame via a horizontal rotating shaft, the inclined arm of the bending swing arm being hinged to a pulling arm, the end of the pulling arm near the discharge side being hinged to the upper corner of a triangular pressing head, the lower corner of the pressing head being hinged to a horizontal hinged seat plate, the horizontal hinged seat plate being horizontally fixedly connected to the bottom of the mounting plate, the third triangle of the pressing head being provided with a pressing platform, the pressing platform being able to press on the top of the stacked paper feeding side of the packaging lids, the inclined arm end of the bending swing arm being connected to the horizontal hinged seat plate near the lower corner of the pressing head via a return spring, and an avoidance notch being provided on the suction cup plate facing the roller.

[0005] Furthermore, air jets are provided on both sides of the aforementioned pressing head. The air jets are connected to the air jet valve through a universal joint pipe. The air jet valve is installed on the cantilever beam and is connected to a pressurized air source.

[0006] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model drives the pressing plate to descend. When the roller contacts the cantilever rod, it presses it down, causing the bending swing arm to swing. Then, the bending swing arm pulls the pulling arm to move. After the pulling arm moves to the left, it pulls the pressing head to release the pressed box cover card. Under the adsorption of the adsorption mechanism, the box cover card is adsorbed, which can realize the automatic opening of the box cover card feeding end. After the upper box cover card is adsorbed and sent out, the lower card is pressed by the pressing head under the action of the pull rope spring. No additional power source is required, which greatly reduces the cost. Attached Figure Description

[0008] Figure 2 This is a schematic diagram of the guide plate installation structure. Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0010] Example 1: Refer to Figure 1-2 As shown, the feeding end pressing mechanism for the cardboard feeding device for wine box packaging lids includes a vertical cantilever 109 located on the feeding side of the bottom of the pressing plate 105. A roller 110 is rotatably connected to the end of the vertical cantilever 109. A horizontal cantilever 111 has a downwardly curved end to facilitate contact between the roller and the cantilever 110. The roller 110 can touch the horizontal cantilever 111. The horizontal cantilever 111 is connected to the horizontal arm of a V-shaped bending swing arm 112. The corner of the bending swing arm 112 is rotatably connected to a mounting plate 19 located at the bottom of the cylinder base 9 via a horizontal pivot. The inclined arm of the bending swing arm 112 is hinged to a pulling arm 113. The end of the pulling arm 113 near the discharge side is hinged to one upper corner of a triangular pressing head 114, and the lower corner of the pressing head 114 is hinged to... On the horizontal hinged base plate 115, which is horizontally fixed to the bottom of the mounting plate 19, the pressing head 114 has a pressing platform 116 set in the triangular part. The pressing platform can press on the top of the feeding side of the stacked packaging box cover card 6. The inclined arm end of the bending swing arm 112 is also connected to the horizontal hinged base plate 115 near the lower corner of the pressing head 114 through the return spring 117. The suction cup plate 102 has an avoidance notch 118 facing the roller 110. By driving the pressing plate to descend, when the roller contacts the cantilever rod and presses it down, it drives the bending swing arm 112 to swing. Then the bending swing arm 112 pulls the pulling arm to move. After the pulling arm moves to the left, it pulls the pressing head 114 to release the pressed box cover card and adsorbs the box cover card under the adsorption action of the adsorption mechanism.

[0011] To improve the adsorption and separation effect and prevent adjacent box cover cards from sticking together, air jets 11 are provided on both sides of the pressing head 114. The air jets 11 are connected to the air jet valve 13 through the universal joint tube 12. The air jet valve 13 is installed on the cantilever beam 4 and is connected to a pressurized air source. After releasing the pressing head, the air jets blow air to separate the adjacent box cover cards, avoiding the adsorption of multiple cards due to adhesion. The universal joint tube can quickly achieve the orientation and positioning of the air jets, find the optimal air jet position adjustment, and adapt to the rapid conversion and adjustment of box cover cards of different sizes.

[0012] Example 2: Refer to Figure 1-2 As shown, the feeding device for box lid cardboard of wine box packaging includes a suction cup mechanism 1, a double-rod lifting cylinder 2, and a pushing cylinder 3. The suction cup mechanism 1 is installed at the output end of the double-rod lifting cylinder 2. The cylinder seat of the double-rod lifting cylinder 2 is fixedly connected to the T-shaped sliding plate 7. The T-shaped sliding plate 7 is connected to the cantilever beam 4 through the slider guide pair 4. The cantilever beam 4 is fixedly connected to the storage rack 5 through the portal frame 20. The suction cup mechanism 1 can extend to the box lid cardboard 6 on the storage rack 5 to adsorb and transport it to the conveyor belt 8. The cylinder seat of the pushing cylinder 3 is installed on the cylinder seat frame 9 set at the bottom of the cantilever beam 4 on the feeding side. The cylinder rod of the pushing cylinder 3 is connected to the T-shaped sliding plate 7. After the box lid cardboard is adsorbed by the suction cup, one end of the box lid is sent into the conveyor belt by the moving mechanism formed by the lifting cylinder and the pushing cylinder. Under the transport of the conveyor belt, the suction cup is released, realizing the feeding of box lids one by one, avoiding the transport of multiple sheets during the adsorption process, and facilitating single sheet transport control.

[0013] To protect the suction cups and prevent damage to the packaging box lid card, the suction cup mechanism 1 includes multiple vacuum suction cups 101 and a suction cup plate 102. The multiple vacuum suction cups 101 are mounted on the suction cup plate 102. The suction cup plate 102 is connected to four guide sleeves 104 via four guide rods 103. The four guide sleeves 104 are arranged on a pressing plate 105. Compression springs 106 are sleeved on the four guide rods 103. The two ends of the compression springs 106 abut against the suction cup plate 102 and the pressing plate 105, respectively. The pressing plate 105 is fixedly connected to a connecting plate 107 at the output end of the double-rod lifting cylinder 2. After the four guide rods 103 extend out of the pressing plate 105, a limiting ring platform 108 is provided. By setting the compression springs, a buffering protection effect can be provided during the downward pressing process, avoiding damage to the vacuum suction cups and the box lid card caused by excessively fast downward impact. Moreover, the elastic buffer can more stably achieve vacuum adsorption onto the box lid card, facilitating stable adsorption and conveying onto the conveyor belt.

[0014] To automatically open the mechanism for pressing and stacking the box lid cardboard, a vertical cantilever 109 is provided on the bottom feeding side of the pressing plate 105. A roller 110 is rotatably connected to the end of the vertical cantilever 109. A downwardly curved part is provided at the end of the horizontal cantilever 111 to facilitate contact between the roller and the roller 110. The roller 110 can touch the horizontal cantilever 111. The horizontal cantilever 111 is connected to the horizontal arm of the V-shaped bending swing arm 112. The corner of the bending swing arm 112 is rotatably connected to the mounting plate 19 at the bottom of the cylinder seat 9 via a horizontal pivot. The inclined arm of the bending swing arm 112 is hinged to the pulling arm 113. The end of the pulling arm 113 near the discharge side is hinged to the upper corner of the triangular pressing head 114. The lower corner of the pressing head 114 is hinged to the horizontal hinged base plate. On 115, the horizontal hinged base plate 115 is horizontally fixedly connected to the bottom of the mounting plate 19. The pressing head 114 is provided with a pressing platform 116 in the third triangle. The pressing platform can press on the top of the stacked packaging box cover card 6 on the feeding side. The inclined arm end of the bending swing arm 112 is also connected to the horizontal hinged base plate 115 near the lower corner of the pressing head 114 through a return spring 117. The suction cup plate 102 is provided with an avoidance notch 118 facing the roller 110. The pressing plate is driven to descend by the double-rod lifting cylinder. When the roller contacts the cantilever rod and presses it down, it drives the bending swing arm 112 to swing. Then the bending swing arm 112 pulls the pulling arm to move. After the pulling arm moves to the left, it pulls the pressing head 114 to release the pressed box cover card and adsorbs the box cover card under the adsorption action of the adsorption mechanism.

[0015] To achieve single-layer lifting control, the storage rack 5 is equipped with an electrically lifting storage rack 10. The storage rack 10 includes a lifting plate 1001. The two sides of the lifting plate 1001 are connected to the two side walls of the portal frame 20 through two pairs of lifting slider guide rails 1002. The portal frame 20 is fixedly connected to the bottom of the storage rack 5. Two chain drive mechanisms 1003 are installed on the two side walls. The chain on one side of each chain drive mechanism 1003 is fixedly connected to the side of the storage rack 10 through a snap-fit ​​component. The chains on both sides rotate synchronously. The lifting plate can be raised and lowered by rotating the sliding guide rail. It can utilize a single motor with dual-shaft output to drive the drive sprockets of two chain transmission mechanisms, thus reducing the number of motors required, resulting in a more compact structure and easier control. The lifting plate 1001 is equipped with a strip-shaped hole 1004 and includes multiple symmetrically arranged left-right and discharge-end limit rods 1005. The lower end of the limit rod 1005 is fixedly connected to the base plate of the storage rack 5, and the upper end moves through the strip-shaped hole 1004 to form a lid-like storage area with the lifting plate 1001. The frame structure can store two symmetrically placed, integrated box lid cards (the two cards are not cut). This storage rack allows for quick storage of the box lid cards. The box lid cards have notches on the left and right sides, which engage with limiting clips to lift the box lid cards. The cards need to be lifted a certain distance above the upper end of the limiting rods to avoid damaging them. Both the left and right limiting rods 1005 are fixedly connected to an auxiliary support plate 1006. The auxiliary support plate 1006 has limiting grooves. 1005 is inserted into the limiting groove. The auxiliary support plate 1006 is cantilevered to the belt frame of the conveyor belt 8 through the L-shaped cantilever seat 1007. The short end of the cantilever seat 1007 is vertically fixed to the end of the auxiliary support plate 1006, and the long end is horizontally fixed to the belt frame of the conveyor belt 8. The auxiliary support plate 1006 can provide auxiliary limiting support for the upper end of the vertically connected limiting rod, and avoid the inaccurate positioning caused by the top of the paper being stacked too high due to shaking, which would affect the accurate position of the paper being conveyed to the conveyor belt.

[0016] To improve the adsorption and separation effect and prevent adjacent box cover cards from sticking together, air jets 11 are provided on both sides of the pressing head 114. The air jets 11 are connected to the air jet valve 13 through the universal joint tube 12. The air jet valve 13 is installed on the cantilever beam 4 and is connected to a pressurized air source. After releasing the pressing head, the air jets blow air to separate the adjacent box cover cards, avoiding the adsorption of multiple cards due to adhesion. The universal joint tube can quickly achieve the orientation and positioning of the air jets, find the optimal air jet position adjustment, and adapt to the rapid conversion and adjustment of box cover cards of different sizes.

[0017] When paper jams occur during conveyor belt transport, the paper jams in the box lids are suspended by an adsorption mechanism before being conveyed to the conveyor belt. However, the end of the paper jam, suspended near the conveyor belt, cannot quickly adhere to the conveyor belt for transport, thus affecting the stability of the conveyor belt. To address this, guide pressing rollers 14 are suspended on the discharge side of the cantilever beam 4. The four corners of the top plate of the guide pressing roller 14's wheel frame are connected to the cantilever beam 4 via four suspension ropes 15. The guide pressing roller 14 is located above the feed end of the conveyor belt 8, and the lowest point of the guide pressing roller 14's wheel surface is 1-1.5mm from the top surface of the conveyor belt 8. By setting up guide pressing rollers with a guiding function, the conveyor belt can be properly conveyed. The box cover card, suspended at one end, is quickly guided into the limiting slot on the conveyor belt, and the rollers press it firmly against the conveyor belt for transport. This facilitates smooth transport after the suction cup is released and improves the stability of the box cover card as it enters the conveyor belt, preventing damage caused by the end of the box cover card hitting the limiting structure on the conveyor belt. Flexible paper sheets are also provided on both sides of the entry end of the limiting slot to prevent wear during the lowering of the front end of the card. The guide pressing rollers connected by flexible ropes can play a buffering role, preventing excessive force on the box cover card due to rigid connection and damage. Under the gravity of the guide pressing rollers, the box cover card is kept pressed firmly against the conveyor belt.

[0018] To safely deliver the packaging box lid card and prevent it from rubbing against the limit bar, a flexible paper baffle 16 that bends towards the conveyor belt is installed on the storage rack 10 below the guide pressing roller 14. The flexible paper baffle can provide auxiliary support and transition when the end of the box lid card (the end before entering and the end after the suction cup puts down the card) is suspended and bent downwards, preventing the decorative glossy surface of the box lid card from rubbing against the top of the limit bar and causing damage or scratches, thus improving the safety of conveying. In addition, it can play a better role in directional movement in conjunction with the guide pressing roller. A bent flexible guide card 17 is attached to the output side of the guide pressing roller 14. The flexible guide card 17 is connected to the pressing block 18 set on the conveyor belt 8. The pressing block 18 is fixedly connected to the belt frame of the conveyor belt 8 through the frame and maintains a gap with the belt. This structure can play a guiding role, guiding the upwardly bent card under the pressing block 18, preventing the card from bending and hitting the pressing block when passing through the guide pressing roller 14.

[0019] Operating principle: When in use, the stacked box cover cards are placed in the storage frame structure. The lifting cylinder and the pushing cylinder control the adsorption mechanism to be biased towards the feeding side to adsorb the box cover cards. After adsorption, the lifting height is higher than the limit bar, and the pushing mechanism is controlled to move the adsorbed and lifted box cover cards forward, embedding the head end of the box cover cards into the gap between the guide pressing roller and the conveyor belt.
