Description

Technical Field

[0001] The invention relates to the technical field of foam packaging shell production, in particular to automatic production equipment for fragile packaging shells. Background Art

[0002] Fragile packaging is a container specifically designed to protect fragile items from damage during transport and storage. These packaging typically incorporates cushioning properties, such as foam, to absorb and disperse impact. Foam packaging is a commonly used packaging material primarily used to protect fragile, valuable, or shock-resistant items from damage during transport and storage.

[0003] Currently, the production of foam packaging shells requires cutting. However, due to the light weight of foam, the foam board is unstable and easily broken during the cutting process, resulting in foam debris, which affects the production efficiency of the foam packaging shell. At the same time, the cut foam part is easily stuck inside the annular blade, making it inconvenient to remove it, affecting subsequent operations and reducing production efficiency. Summary of the Invention

[0004] Based on the above-mentioned existing technical problems, the present invention proposes an automatic production device for fragile product packaging shells.

[0005] The present invention proposes an automatic production equipment for fragile packaging shells, including a foam board, a foam bottom plate, a foam hole digger, and a support plate and a proximity switch arranged on the foam hole digger.

[0006] Wherein, the transport mechanism includes a first screw, and the foam board is transported to the upper surface of the third bracket through the rotation of the first screw.

[0007] Wherein, the digging mechanism includes a push rod, and the foam in the holes of the foam board is pushed out by the push rod.

[0008] Wherein, the gluing mechanism bonds the foam board and the foam bottom board together.

The movement of the moving block drives the pushing plate to move through the connecting plate, so that the movement of the pushing plate pushes the foam board to the third bracket.

[0013] Preferably, the digging mechanism also includes pushing cylinders distributed in a rectangular array on the inner surface of the third bracket, and another proximity switch is embedded in the upper surface of the third bracket. One end of the piston rod of the four pushing cylinders is fixedly sleeved with a support plate, and the lower surface of the support plate is provided with springs distributed in a rectangular array. The free end of the spring is fixedly connected to the push rod, and the lower surface of the support plate is installed with metal sleeves distributed in a rectangular array. The spring and the push rod are both located inside the metal sleeve.

[0014] Through the above technical solution, the extension and retraction of the four push cylinder piston rods drive the support plates connected to them to move up and down. The shape of the metal sleeve is consistent with the shape of the holes on the foam board, which makes it convenient for the metal sleeve and the push rod on the support plate to push the foam in the holes of the foam board out. When the support plate is separated from the foam board, the spring provides a restoring force to pop out the foam in the holes of the foam board. At the same time, the use of the spring can ensure the stability and reliability of the push rod during the digging process, and the proximity switch controls the extension and retraction stroke of the push cylinder piston rod.

[0018] Through the above technical solution, the extension and retraction of the telescopic cylinder piston rod drives the frame plate connected to it to move up and down until the frame plate contacts the foam plate, so that the ejector pin is inserted into the foam plate, thereby facilitating the transportation of the foam plate under the movement of the slider on the second self-driven slide rail.

[0019] Preferably, one end of the piston rod of the telescopic cylinder extends into the frame plate and is fixedly sleeved with a receiving plate, and the upper ends of the plurality of ejectors are fixedly connected to the lower surface of the receiving plate.

[0021] Preferably, a glue rack is provided on one side surface of the loading conveyor belt, a roller is installed on the inner wall of the glue rack through a bearing, the surface of the roller contacts the glue in the glue rack, and the surface of the roller extends out of the glue rack.

[0022] Through the above technical solution, the movement of the slider on the second self-driven slide rail drives the bottom of the foam board to contact the surface of the roller, and as the foam board moves, the roller rotates, so that the bottom of the foam board is covered with glue, and then drives the foam board covered with glue to contact the foam bottom plate.

[0023] Preferably, a workbench is provided on one side surface of the glue rack, a pushing rack is provided on one side surface of the workbench, and a material unloading conveyor belt is provided on one side surface of the workbench away from the pushing rack.

[0026] Through the above technical solution, the foam base plate is placed between the two limit plates, and the rotation of the stepper motor output shaft drives the second screw connected to it to rotate. The rotation of the second screw drives the T-shaped block connected to it to move along the groove and the inner wall of the limit plate. The movement of the T-shaped block drives the third multi-stage telescopic rod to move, thereby driving the concave pushing plate to move, and then the foam base plate is pushed to the workbench through the concave pushing plate. After the foam plate and the foam base plate are bonded, the third multi-stage telescopic rod is extended through the concave pushing plate to push the material to the unloading conveyor belt.

The bottom of the foam board is in contact with the roller on the glue rack and is stained with glue. The contact between the frame plate and the foam board prevents the ejector pin from warping when inserted into the foam board. At the same time, the movement of the receiving plate within the frame makes it easy to separate the ejector pin from the foam board, thereby achieving the effect of gluing and transportation and improving production efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] Reference Figures 1-11 , an automatic production equipment for fragile packaging shells, including a foam board 1, a foam bottom plate 2, a foam hole digger 3, and a support plate 4 and a proximity switch 16 arranged on the foam hole digger 3, a first bracket 5 is provided on one side surface of the foam hole digger 3, a second bracket 6 is provided on the side surface of the foam hole digger 3 away from the first bracket 5, a transportation mechanism is provided on the surface of the second bracket 6, a third bracket 8 is provided on one side surface of the second bracket 6, a hole digging mechanism is provided on the surface of the third bracket 8, a feeding conveyor belt 10 is provided on one side surface of the third bracket 8, and a gluing mechanism is provided on the outer surface of the feeding conveyor belt 10.

[0044] The first multi-stage telescopic rod 14 is symmetrically installed on the upper surface of the first bracket 5, and one end of the first multi-stage telescopic rod 12 is fixedly connected to the L-shaped plate 13. The surface of the L-shaped plate 13 is fixedly connected to the surface of the support plate 4. The second multi-stage telescopic rod 14 is symmetrically installed on the upper surface of the first bracket 5. The second multi-stage telescopic rod 14 is fixedly connected to the push plate 15 at one end. The extension of the first multi-stage telescopic rod 12 drives the L-shaped plate 13 connected to it to move, and the movement of the L-shaped plate 13 drives the support plate 4 connected to it to move in the foam excavator 3, so that the foam board 1 is driven into the foam excavator 3 by the support plate 4, and is moved out of the foam excavator 3 after the holes in the foam board 1 are dug. Then, the extension of one end of the second multi-stage telescopic rod 14 drives the push plate 15 to move, so that the push plate 15 transports the foam board 1 after the holes are dug to the second bracket 6.

[0045] In order to transport the foam board 1 after the holes are opened to the third bracket 8, the provided transport mechanism includes a first screw 7, and the rotation of the first screw 7 drives the foam board 1 to be transported to the upper surface of the third bracket 8.

[0046] In order to drive the first screw 7 to rotate, the transportation mechanism also includes a driving motor 71 fixedly mounted on one side surface of the second bracket 6, one end of the output shaft of the driving motor 71 is fixedly sleeved with one end of the first screw 7, and the two ends of the first screw 7 are mounted on the inner surface of the second bracket 6 through bearings. The surface of the first screw 7 is threadedly sleeved with a moving block 72, and the upper surface of the moving block 72 is symmetrically installed with connecting plates 73. The end of the connecting plate 73 away from the moving block 72 is fixedly connected to a pushing plate 74, and the rotation of the output shaft of the driving motor 71 drives the first screw 7 connected thereto to rotate. The rotation of the first screw 7 drives the moving block 72 connected thereto to move along the inner surface of the second bracket 6, and the movement of the moving block 72 drives the pushing plate 74 to move through the connecting plate 73, so that the movement of the pushing plate 74 pushes the foam board 1 to the third bracket 8.

[0047] In order to push out the foam in the hole of the foam board 1 so that the hole on the foam board 1 passes through the foam board 1, the provided hole-digging mechanism includes a push rod 9, which pushes out the foam in the hole of the foam board 1.

[0048] In order to facilitate the insertion of the push rod 9 into the hole on the foam board 1, the digging mechanism also includes a push cylinder 91 distributed in a rectangular array on the inner surface of the third bracket 8, and another proximity switch 16 is embedded in the upper surface of the third bracket 8. One end of the piston rod of the four push cylinders 91 is fixedly sleeved with a support plate 92. The lower surface of the support plate 92 is provided with a spring 93 distributed in a rectangular array. The free end of the spring 93 is fixedly connected to the push rod 9. The lower surface of the support plate 92 is provided with a metal sleeve 94 distributed in a rectangular array. The spring 93 and the push rod 9 are both located inside the metal sleeve 94. The support plate 92 connected to it is driven up and down by the extension and retraction of the piston rods of the four push cylinders 91. The shape of the metal sleeve 94 is consistent with the shape of the hole on the foam board 1, which makes it convenient for the metal sleeve 94 and the push rod 9 on the support plate 92 to push the foam in the hole of the foam board 1 out, and when the support plate 92 is separated from the foam board 1, the spring 93 provides a restoring force to eject the foam in the hole of the foam board 1. At the same time, the use of the spring 93 can ensure the stability and reliability of the push rod 9 during the digging process, and the proximity switch 16 controls the extension and retraction stroke of the piston rod of the push cylinder 91.

[0049] In order to clamp and position the foam board 1 and transport the foam board 1 with holes to the loading conveyor 10, a first self-driving slide rail 95 is symmetrically distributed on the upper surface of the third bracket 8, and a flexible clamp 96 is fixedly installed on the slider surface of the first self-driving slide rail 95. The flexible clamp 96 is used to limit and clamp the foam board 1 transported to the third bracket 8 through the second bracket 6, and the flexible clamp 96 drives the foam board 1 to move during the movement of the slider on the first self-driving slide rail 95, which can ensure that the foam board 1 is in the correct position and prevent it from shifting during the digging process.

[0050] By setting up a hole-digging mechanism, the metal sleeve 94 is used to facilitate cutting of the foam in the holes of the foam board 1, and the elastic force of the spring 93 is used to enable the push rod 9 to push the foam stuck in the metal sleeve 94 out of the metal sleeve 94, thereby achieving a better hole-digging effect and improving production efficiency.

[0051] Among them, in order to bond the foam board 1 and the foam bottom plate 2 together, the gluing mechanism provided includes a support frame 11 fixedly installed on the outer surface of the feeding conveyor belt 10, and the upper surface of the support frame 11 is symmetrically installed with a second self-driving slide rail 111, and the slider surfaces of the two second self-driving slide rails 111 are fixedly connected with a connecting block 112, and the lower surfaces of the two connecting blocks 112 are fixedly connected with a mounting plate 113, and the lower surface of the mounting plate 113 is fixedly installed with a telescopic cylinder 114, and the piston rod surface of the telescopic cylinder 114 is slidably clamped with a frame plate 115, and the lower surface of the frame plate 115 is distributed in a rectangular array and is penetrated by a ejector pin 116. The frame plate 115 connected thereto is driven up and down by the telescopic movement of the piston rod of the telescopic cylinder 114 until the frame plate 115 contacts the foam board 1, so that the ejector pin 116 is inserted into the foam board 1, thereby facilitating the transportation of the foam board 1 under the movement of the slider on the second self-driving slide rail 111.

[0052] In order to separate the ejector pin 116 from the foam board 1, one end of the piston rod of the telescopic cylinder 114 extends into the frame plate 115 and is fixedly sleeved with a receiving plate 117. The upper ends of multiple ejector pins 116 are fixedly connected to the lower surface of the receiving plate 117. When the frame plate 115 contacts the foam board 1, the extension of the piston rod of the telescopic cylinder 114 drives the receiving plate 117 to move downward in the frame plate 115. The downward movement of the receiving plate 117 drives the ejector pin 116 to insert into the foam board 1. At the same time, when the piston rod of the telescopic cylinder 114 contracts, the ejector pin 116 is separated from the foam board 1.

[0053] In order to facilitate the application of glue on the bottom of the foam board 1, a glue rack 118 is provided on one side surface of the loading conveyor belt 10. A roller 119 is installed on the inner wall of the glue rack 118 through a bearing. The surface of the roller 119 contacts the glue in the glue rack 118, and the surface of the roller 119 extends out of the glue rack 118. The movement of the slider on the second self-driven slide rail 111 drives the bottom of the foam board 1 to contact the surface of the roller 119, and the roller 119 rotates as the foam board 1 moves, so that the bottom of the foam board 1 is covered with glue, and then the foam board 1 covered with glue is driven to contact the foam bottom plate 2.

[0054] In order to facilitate the bonding of the foam board 1 and the foam base plate 2 and to transport the finished materials, a workbench 120 is provided on one side surface of the glue rack 118, a pushing rack 121 is provided on one side surface of the workbench 120, a material unloading conveyor belt 122 is provided on the side surface of the workbench 120 away from the pushing rack 121, a stepping motor 123 is fixedly installed on one side surface of the pushing rack 121, a groove 124 is provided on the upper surface of the pushing rack 121, and the inner wall of the groove 124 is passed through the groove 124. A second screw 125 is installed through a bearing, one end of the output shaft of the stepping motor 123 is fixedly sleeved with one end of the second screw 125, a T-shaped block 126 is threadedly sleeved on the surface of the second screw 125, the surface of the T-shaped block 126 is slidably engaged with the inner wall of the groove 124, and the upper surface of the T-shaped block 126 is symmetrically installed with a third multi-stage telescopic rod 127, one end of each of the two third multi-stage telescopic rods 127 is fixedly connected with a concave pushing plate 128, and the upper surface of the pushing frame 121 is symmetrical. The limiting plates 129 are distributedly installed, and the two side surfaces of the T-shaped block 126 and the concave pushing plate 128 are respectively slidably connected to the inner walls of the two limiting plates 129. The foam base plate 2 is placed between the two limiting plates 129. The rotation of the output shaft of the stepping motor 123 drives the second screw 125 connected thereto to rotate. The rotation of the second screw 125 drives the T-shaped block 126 connected thereto to move along the groove 124 and the inner wall of the limiting plate 129. The movement of the T-shaped block 126 drives the third multi- The multi-stage telescopic rod 127 moves, thereby driving the concave pushing plate 128 to move, and then the concave pushing plate 128 drives the foam base plate 2 to be pushed onto the workbench 120. After the foam board 1 is glued, it is transported to the workbench 120 under the action of the second self-driving slide rail 111 and bonded to the foam base plate 2 on the workbench 120. After the foam board 1 is bonded to the foam base plate 2, the third multi-stage telescopic rod 127 extends through the concave pushing plate 128 to drive the material to be pushed onto the unloading conveyor belt 122.

[0055] By setting up a gluing mechanism, the extension and contraction of the piston rod of the push cylinder 91 is used to drive the ejector pin 116 to be inserted into the foam board 1, thereby facilitating the transportation of the foam board 1, so that the bottom of the foam board 1 contacts the roller 119 on the glue rack 118 and is stained with glue, and the contact between the frame plate 115 and the foam board 1 is used to prevent the ejector pin 116 from warping when inserted into the foam board 1. At the same time, the movement of the receiving plate 117 within the frame makes it easy to separate the ejector pin 116 from the foam board 1, thereby achieving the effect of gluing and transportation and improving production efficiency.

[0056] Working principle: When in use, the extension of the first multi-stage telescopic rod 12 drives the support plate 4 to move outward through the L-shaped plate 13, and the foam board 1 is placed on the designated position of the support plate 4. Then, the contraction of the first multi-stage telescopic rod 12 drives the support plate 4 to enter the foam digger 3 through the L-shaped plate 13, so that the foam board 1 is located at the designated position in the foam digger 3. The foam digger 3 performs hot-melt punching on the surface of the foam board 1. Then, the continued contraction of the first multi-stage telescopic rod 12 drives the support plate 4 to move out of the foam digger 3 from the other side through the L-shaped plate 13, and the second multi-stage telescopic rod 14 on the first bracket 5 is activated through the proximity switch 16. The extension of the second multi-stage telescopic rod 14 drives the foam board 1 on the support plate 4 to be pushed onto the second bracket 6 through the push plate 15;

[0057] Then the driving motor 71 and the four pushing cylinders 91 are started, and the rotation of the output shaft of the driving motor 71 drives the first screw 7 connected thereto to rotate, and the rotation of the first screw 7 drives the moving block 72 connected thereto to move along the inner surface of the second bracket 6, and the movement of the moving block 72 drives the pushing plate 74 to move through the connecting plate 73, and then another proximity switch 16 is used to make the pushing plate 74 move to push the foam board 1 to the third bracket 8, and at the same time, the extension of the piston rods of the four pushing cylinders 91 drives the supporting plate 92 connected thereto to move upward, and The flexible clamp 96 on the slider of the first self-driving slide 95 positions and clamps the transported foam board 1, and under the action of the first self-driving slide 95, the foam board 1 is positioned at the specified position of the third bracket 8, and then the piston rods of the four pushing cylinders 91 move downward to drive the support plate 92 close to the foam board 1, so that the metal sleeve 94 and the push rod 9 on the support plate 92 enter the hole of the foam board 1, and when the pushing cylinder 91 drives the support plate 92 to move upward, the spring 93 on the push rod 9 provides a restoring elastic force to eject the foam in the hole of the foam board 1;

[0058] Then, the first self-driven slide rail 95 drives the foam board 1 close to the loading conveyor belt 10. As the loading conveyor belt 10 rotates, the foam board 1 is driven to the specified position, and at the same time, the foam base plate 2 is placed between the two limit plates 129 on the pushing frame 121. The stepper motor 123 on the pushing frame 121 is started, and the rotation of the output shaft of the stepper motor 123 drives the second screw 125 connected thereto to rotate. The rotation of the second screw 125 drives the T-shaped block 126 connected thereto to move along the groove 124 and the inner wall of the limit plate 129. The movement of the T-shaped block 126 drives the third multi-stage telescopic rod 127 to move, thereby driving the concave pushing plate 128 to move, and then driving the foam base plate 2 to be pushed onto the workbench 120 through the concave pushing plate 128.

[0059] The second self-driving slide 111 is started again. Under the action of the second self-driving slide 111, the frame plate 115 is driven to be above the foam board 1, and when the piston rod of the telescopic cylinder 114 is extended, the frame plate 115 connected thereto is driven to move downward until the frame plate 115 contacts the foam board 1. As the piston rod of the telescopic cylinder 114 is extended, the receiving plate 117 is driven to move downward in the frame plate 115. The downward movement of the receiving plate 117 drives the ejector pin 116 to insert into the foam board 1. At the same time, the bottom of the foam board 1 is driven to contact the surface of the roller 119 through the movement of the slider on the second self-driving slide 111. As the foam board 1 moves, the roller 119 rotates, so that the bottom of the foam board 1 is stained with glue, and the foam board 1 stained with glue is driven to contact and bond with the foam bottom plate 2.
