Description

Technical Field

[0001] This invention relates to the field of cardboard box production and processing technology, and in particular to a box edge binding device for cardboard box production. Background Technology

[0002] Cardboard box production is a complex process involving multiple technologies and techniques, primarily used to manufacture packaging materials for the protection and transport of various goods. The main raw materials for cardboard boxes are corrugated cardboard, kraft paper, and recycled paper. Corrugated cardboard consists of two layers of flat paper on the inside and outside, with a corrugated layer in the middle. This structure allows the cardboard box to be lightweight while maintaining good compression resistance and tear resistance. The binding process in cardboard box production is a crucial step in assembling the various cardboard components into the final product; binding equipment is typically used to assemble the cardboard boxes into a single unit.

[0003] Most existing carton binding devices are semi-automated. During the carton binding process, it is usually necessary to manually fold and align the two sides of the carton to be bound before the binding machine binds the carton. This can result in misalignment of the two sides of the carton, leading to poor carton binding quality. Summary of the Invention

[0004] To overcome the shortcomings of existing carton binding devices, such as misalignment of the two sides of the carton, which leads to poor carton binding quality, this invention provides a carton edge binding device for carton production. This device can correct and fix the position of the cardboard before binding, thereby improving the binding quality of the cardboard.

[0005] The technical solution of the present invention is: a carton edge binding device for carton production, comprising a bracket, a support plate on the bracket, four guide rods and an electric push rod on the bracket, a mounting frame on the telescopic rod of the electric push rod, a binding machine on the mounting frame, two pressure frames slidably connected on the mounting frame, and a return spring connecting the two pressure frames and the mounting frame.

[0006] In one embodiment, the support plate has rectangular perforations.

[0007] In one embodiment, a positioning mechanism is also included. The positioning mechanism includes a multi-stage sleeve hydraulic cylinder. The multi-stage sleeve hydraulic cylinder is installed inside the bracket. The first telescopic rod of the multi-stage sleeve hydraulic cylinder is provided with a guide frame. The guide frame and the bracket are slidably connected. Two sliding rods are slidably connected inside the bracket. Both sliding rods are engaged with the guide frame. Lifting rods are slidably connected to both sliding rods. Tension springs are connected between the two lifting rods and the two sliding rods. A push plate is slidably connected to the bracket. Several tension springs are connected between the push plate and the bracket. Two top blocks are provided on the sliding rods near the push plate. Two sets of guide plates are provided inside the bracket. The two lifting rods are engaged with the two sets of guide plates respectively.

[0008] In one embodiment, a flipping mechanism is also included. The flipping mechanism includes a rotating plate, and four rotating plates are rotatably connected to the bracket. Each rotating plate is connected to the bracket with a torsion spring. Two racks and one rack are slidably connected inside the bracket. The rack is connected to the second telescopic rod of the multi-stage sleeve hydraulic cylinder. Both racks are connected to the racks. One-way bearings are provided on two rotating plates on one side of the bracket, and drive gears are provided on the two one-way bearings. Spur gears are provided on two rotating plates on the other side of the bracket.

[0009] In one embodiment, a pressing mechanism is also included. The pressing mechanism includes a rotating shaft. Two rotating shafts are rotatably connected to the bracket. Each of the two rotating shafts is provided with two pressure rods and a rotating gear. Two rotating gears are slidably connected inside the bracket. A pressure spring is connected between each of the two rotating gears and the bracket. Two top frames are slidably connected inside the bracket. The two top frames are respectively connected to the two gears.

[0010] In one embodiment, a correction mechanism is also included. The correction mechanism includes push blocks, two push blocks are slidably connected to each of the two lifting rods, guide frames are slidably connected to each of the two lifting rods, four push blocks are respectively engaged with the two guide frames, a pressure spring is connected between the guide frames and the lifting rods, a squeezing block is slidably connected to each of the two lifting rods, and two protrusions are provided inside the bracket.

[0011] In one embodiment, both bumps are partially raised.

[0012] In one embodiment, it also includes limit blocks, with two limit blocks provided on each of the two pressure blocks, and two transmission rods and two limit plates slidably connected on the mounting bracket, with the four limit blocks respectively engaging with the two transmission rods.

[0013] The beneficial effects are: 1. During the movement of the sliding rod, the lifting rod will move together. During the movement of the lifting rod, it will be squeezed by the guide plate, causing the lifting rod to extend out of the bracket. The tension spring one is stretched. After the lifting rod extends out of the bracket and continues to move, it will clamp the cardboard, so that the position of the cardboard will be initially corrected. During the movement of one of the sliding rods, the top block will move together. During the movement of the top block, it will hit the push plate, causing the push plate to move closer to the cardboard. The tension spring two is stretched. During the movement of the push plate, it will contact the cardboard. The push plate will further correct the position of the cardboard and prevent the cardboard from tilting. In this way, the position of the cardboard can be corrected and fixed before binding, thereby improving the binding quality of the cardboard.

[0014] 2. During the movement of the top frame, the rotating rack is squeezed. The rotating rack, under pressure, moves towards the direction of extending out of the support. The pressure spring is compressed, and the rotating rack meshes with the rotating gear. The rotation of the rotating gear drives the rotating shaft to rotate, which in turn drives the pressure rod to rotate, causing the pressure rod to rotate towards the cardboard. After the pressure rod contacts the cardboard and presses it down, the rotating rack stops moving. Subsequently, the second rack meshes with the drive gear. In this way, the corrected cardboard can be further fixed before the cardboard is flipped, thereby further improving the binding quality of the cardboard.

[0015] 3. During the movement of the extrusion block, it will be squeezed by the protrusion, causing the extrusion block to extend into the lifting rod. The extrusion block will squeeze the guide frame, causing the guide frame to move away from the extrusion block. The pressure spring is compressed. During the movement of the guide frame, it will drive the push block to extend out of the lifting rod. During the extension of the push block out of the lifting rod, it will contact the cardboard, thereby pushing the cardboard and further aligning the position of the cardboard, thus improving the binding quality of the cardboard.

Detailed Implementation

[0034] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] Example 1: A carton edge binding device for carton production, such as... Figures 1-12 As shown, it includes a bracket 1, a support plate 2 on the bracket 1, four guide rods 3 and an electric push rod 4 on the bracket 1, an installation frame 5 on the telescopic rod of the electric push rod 4, a binding machine 6 on the installation frame 5, and two pressure frames 7 slidably connected to the installation frame 5. A return spring 8 is connected between the two pressure frames 7 and the installation frame 5.

[0036] The support plate 2 has rectangular perforations.

[0037] It also includes a positioning mechanism. The positioning mechanism is provided on the bracket 1 and is used to position the cardboard 91. The positioning mechanism includes a multi-stage sleeve hydraulic cylinder 101. The multi-stage sleeve hydraulic cylinder 101 is provided inside the bracket 1. The first telescopic rod of the multi-stage sleeve hydraulic cylinder 101 is provided with a guide frame 102. The guide frame 102 and the bracket 1 are slidably connected. Two sliding rods 103 are slidably connected inside the bracket 1. Both sliding rods 103 are engaged with the guide frame 102. Lifting rods 104 are slidably connected to both sliding rods 103. Tension springs 105 are connected between the two lifting rods 104 and the two sliding rods 103. A push plate 106 is slidably connected to the bracket 1. Several tension springs 107 are connected between the push plate 106 and the bracket 1. Two top blocks 108 are provided on the sliding rods 103 near the push plate 106. Two sets of guide plates 109 are provided inside the bracket 1. The two lifting rods 104 are engaged with the two sets of guide plates 109 respectively.

[0038] It also includes a flipping mechanism. The bracket 1 is equipped with a flipping mechanism for folding cardboard 91. The flipping mechanism includes a rotating plate 111. Four rotating plates 111 are rotatably connected to the bracket 1. Each rotating plate 111 is connected to the bracket 1 with a torsion spring 112. Two racks 113 and one rack 2 114 are slidably connected inside the bracket 1. The rack 2 114 is connected to the second telescopic rod of the multi-stage sleeve hydraulic cylinder 101. Both racks 113 are connected to the rack 2 114. One-way bearings 115 are provided on the two rotating plates 111 on one side of the bracket 1. Both one-way bearings 116 are provided on the two one-way bearings 115. The two rotating plates 111 on the other side of the bracket 1 are provided with spur gears 117.

[0039] Initially, cardboard 91 is conveyed onto support 1 via conveyor belt 9, passing under support plate 2. During its movement onto support 1, guide rod 3 on support 1 provides initial guidance. After cardboard 91 is fully on support 1, the side of cardboard 91 with the protruding part for binding faces conveyor belt 9. The user controls the extension of the first telescopic rod of multi-stage sleeve hydraulic cylinder 101, which drives guide frame 102 to move closer to conveyor belt 9. During this movement, guide frame 102 presses against two sliding rods 103, causing them to move closer together. This movement of sliding rods 103 also moves lifting rod 104 along with the cardboard. During its movement, the lifting rod 104 is pressed by the guide plate 109, causing it to extend out of the bracket 1. The lifting rod 104 moves into the gap between the cardboard pieces 91, stretching the tension spring 105. As the lifting rod 104 continues to move after extending out of the bracket 1, it clamps the cardboard pieces 91, initially correcting their position. During the movement of one of the sliding rods 103, it drives the top block 108 to move as well. The top block 108 then pushes against the push plate 106, causing it to move closer to the cardboard pieces 91. Stretching spring 107 is stretched, and the push plate 106 contacts the cardboard pieces 91 during its movement, further correcting their position and preventing them from tilting. After the position of the cardboard pieces 91 is corrected... When the first telescopic rod of the multi-stage sleeve hydraulic cylinder 101 stops extending, the second telescopic rod of the multi-stage sleeve hydraulic cylinder 101 extends. The second telescopic rod of the multi-stage sleeve hydraulic cylinder 101 will drive the first rack 113 and the second rack 114 to move together, so that the first rack 113 will extend into the bracket 1 and the second rack 114 will extend out of the bracket 1. The second rack 114 will first mesh with the drive gear 116. The rotation of the drive gear 116 will drive the one-way bearing 115 to rotate. The rotation of the one-way bearing 115 will drive the rotating plate 111 to rotate. The torsion spring 112 is torsion. During the rotation of the rotating plate 111, it will drive the side of the cardboard 91 used for binding with the protruding part to flip onto the support plate 2. The second rack 114 continues to move and disengages from the drive gear 116. The torsion spring 112 returns to its original position. The rotating plate 111 resets, and then the rack 113 meshes with the spur gear 117. The rotation of the spur gear 117 drives the other two rotating plates 111 to rotate, which in turn causes the other side of the cardboard 91 to flip onto the support plate 2. This ensures that the side of the cardboard 91 with the protruding part used for binding is pressed down by the other side of the cardboard 91. Then, the second telescopic rod of the multi-stage sleeve hydraulic cylinder 101 stops extending, and the rack 113 and spur gear 117 remain engaged. Subsequently, the user controls the extension of the electric push rod 4. The extension of the electric push rod 4 causes the mounting frame 5 and the binding machine 6 to move together towards the cardboard 91. During the movement of the mounting frame 5, the pressing frame 7 moves together, causing the pressing frame 7 to contact the cardboard 91 first.During the descent of the pressure frame 7, it presses the two sides of the cardboard 91 together. Restricted by the support plate 2, the pressure frame 7 continues to descend and extends into the mounting frame 5. The return spring 8 is compressed. Subsequently, the binding port of the binding machine 6 contacts the cardboard 91, and the extension rod of the electric push rod 4 stops extending. The user controls the binding machine 6 to bind the carton. After binding, the user controls the extension rod of the electric push rod 4 to retract. The retraction of the electric push rod 4 resets the mounting frame 5 and the pressure frame 7. The return spring 8 resets, causing the pressure frame 7 to extend out of the mounting frame 5. After the electric push rod 4 resets, the user controls the extension rod of the multi-stage sleeve hydraulic cylinder 101 to reset. The second extension rod of the multi-stage sleeve hydraulic cylinder 101 resets, causing the first rack 113 and the second rack 114 to reset. The reset of the first rack 113 resets the spur gear 117, which in turn resets the rotating plate 111. The torsion spring 112 resets. During the reset process, the second rack 114 meshes with the drive gear 116. When the drive gear 116 idles, after the second telescopic rod of the multi-stage sleeve hydraulic cylinder 101 resets, the first telescopic rod of the multi-stage sleeve hydraulic cylinder 101 retracts and resets. The first telescopic rod of the multi-stage sleeve hydraulic cylinder 101 drives the guide frame 102 to reset, the guide frame 102 resets, the sliding rod 103 resets, and the sliding rod 103 resets, driving the lifting rod 104 and the top block 108 to reset. During the reset process, the lifting rod 104 is squeezed by the guide plate 109, causing the lifting rod 104 to retract into the sliding rod 103. The tension spring 105 resets, the top block 108 resets, and the push plate 106 gradually disengages. The tension spring 107 resets, driving the push plate 106 to reset. After the telescopic rod of the multi-stage sleeve hydraulic cylinder 101 resets, the user removes the bound cardboard 91 from the bracket 1, completing the binding of the cardboard 91. This method allows for the correction and fixation of the position of the cardboard 91 before binding, thereby improving the binding quality of the cardboard 91.

[0040] Example 2: Based on Example 1, such as Figures 4-17 As shown, it also includes a pressing mechanism. The support 1 is provided with a pressing mechanism, which is used to further fix the cardboard 91. The pressing mechanism includes a rotating shaft 121. Two rotating shafts 121 are rotatably connected to the support 1. Each of the two rotating shafts 121 is provided with two pressure rods 122 and a rotating gear 123. Two rotating gears 124 are slidably connected inside the support 1. A pressure spring 125 is connected between each of the two rotating gears 124 and the support 1. Two top frames 126 are slidably connected inside the support 1. The two top frames 126 are respectively connected to the two gears 114.

[0041] It also includes a correction mechanism. The lifting rod 104 is equipped with a correction mechanism for further correcting the cardboard 91. The correction mechanism includes push blocks 131. Two push blocks 131 are slidably connected to each of the two lifting rods 104. Guide frames 132 are slidably connected to each of the two lifting rods 104. Four push blocks 131 are respectively engaged with two guide frames 132. A pressure spring 133 is connected between the guide frame 132 and the lifting rod 104. An extrusion block 134 is slidably connected to each of the two lifting rods 104. Two protrusions 135 are provided inside the bracket 1.

[0042] Both bumps 135 are partially raised.

[0043] It also includes limit blocks 14. Each of the two pressure blocks is provided with two limit blocks 14. The mounting bracket 5 is slidably connected to two transmission rods 15 and two limit plates 16. The four limit blocks 14 are respectively engaged with the two transmission rods 15.

[0044] As the second rack 114 extends out of the bracket 1, it moves the top frame 126. During this movement, the top frame 126 presses against the rotating rack 124, causing it to move towards the bracket 1. The pressure spring 125 is compressed, and the rotating rack 124 meshes with the rotating gear 123. The rotation of the rotating gear 123 drives the rotating shaft 121 to rotate, which in turn drives the pressure rod 122 to rotate, causing it to move closer to the cardboard 91. After the pressure rod 122 contacts and presses down on the cardboard 91, the pressure from the top frame 126 on the rotating rack 124 no longer increases, and the rotating rack 124 stops moving. Subsequently, the second rack 114 meshes with the drive gear 116. In this way, the corrected cardboard 91 can be further fixed before flipping, thereby further improving the binding quality of cardboard 91. The toothed bar 114 resets, causing the top frame 126 to reset. The top frame 126 gradually disengages from the rotating toothed bar 124. The pressure spring 125 resets, causing the rotating toothed bar 124 to reset. The reset of the rotating toothed bar 124 causes the rotating gear 123, the rotating shaft 121, and the pressure bar 122 to reset. During the process of the lifting rod 104 extending out of the bracket 1, the lifting rod 104 will drive the push block 131 and the squeezing block 134 to move together, so that the push block 131 moves into the gap between the cardboard 91. During the movement of the squeezing block 134, it will be squeezed by the protrusion 135, so that the squeezing block 134 will extend into the lifting rod 104 and squeeze. The pressure block 134 presses against the guide frame 132, causing the guide frame 132 to move away from the pressure block 134. The pressure spring 133 is compressed. During the movement of the guide frame 132, the push block 131 extends the lifting rod 104. As the push block 131 extends the lifting rod 104, it contacts the cardboard 91, pushing it and further aligning its position, thus improving the binding quality. During the resetting process of the lifting rod 104, the pressure block 134 resets, gradually disengaging from the protrusion 135. The resetting of the pressure spring 133 resets the guide frame 132 and the pressure block 134, and the resetting of the guide frame 132 resets the push block 131. The mounting frame 5 moves closer to the cardboard 91. During the process, the mounting frame 5 will move the limiting block 14, the transmission rod 15, and the limiting plate 16 together. As the pressing frame 7 extends into the mounting frame 5, the pressing frame 7 will move the limiting block 14. The movement of the limiting block 14 will cause the transmission rod 15 to move in the opposite direction, and the movement of the transmission rod 15 will cause the limiting plate 16 to move in the opposite direction, and the movement of the limiting plate 16 will correct and restrict the position of the two sides of the flipped cardboard 91, so that the two sides of the cardboard 91 are more neatly attached and the binding quality of the cardboard 91 is improved. After the binding is completed, the pressing frame 7 resets and causes the limiting block 14 to reset. The reset of the limiting block 14 causes the transmission rod 15 to reset. The reset of the transmission rod 15 causes the limiting plate 16 to reset, so that the limiting plate 16 and the cardboard 91 are separated.
