Description

Technical Field

[0001] The present application relates to the field of conveying devices in carton production lines, and in particular to a conveying device for connecting carton production lines. Background Art

[0002] As a vital component of the modern packaging industry, carton production lines are crucial for improving productivity through efficient and stable operation. The connection and transportation of materials between different steps in the carton production process are crucial for ensuring smooth operation of the entire line. Growing market demand is driving higher demands for automation and reliability in carton production lines, driving the continuous advancement and development of related technologies, providing crucial support for the industry's scaled-up production and cost control.

[0003] In the related art, when cartons are packed, a conveyor is usually used to transport the stacks of cartons to a packing machine in sequence, and then the packing machine packs the stacks of cartons in sequence.

[0004] The above-mentioned related technologies have the following defects: since cartons are light in texture, a stack of cartons is easily offset due to vibration during the transportation process. Summary of the Invention

[0005] In order to ensure that stacks of cartons can be transported stably, the present application provides a carton production line connection and conveying device.

[0006] The present application provides a carton production line connection and conveying device that adopts the following technical solution: A carton production line connection conveying device includes a frame, a conveying mechanism and a holding mechanism. The conveying mechanism includes a plurality of conveying rollers, which are arranged along the width direction of the frame and are evenly distributed in the length direction of the frame; the holding mechanism includes a conveyor belt, which is arranged along the length direction of the frame and is installed above the conveying rollers in a liftable manner.

[0007] By adopting the above technical solution, stacks of cartons are placed on the conveyor rollers, and the conveyor belt descends to press the stacks of cartons against the conveyor rollers. When conveying the stacks of cartons, the conveyor rollers and the conveyor belt operate synchronously to transport the stacks of cartons downstream. In summary, through the coordinated cooperation of the conveyor rollers and the conveyor belt, the stacks of cartons can be clamped and transported, so that the stacks of cartons can be transported stably and without deviation to the downstream.

[0008] Preferably, the holding mechanism further includes a lifting bracket, which is installed on the frame on the conveying roller in a liftable manner; and the conveyor belt is installed on the lifting bracket.

[0009] By adopting the above technical solution and adjusting the height of the lifting bracket, the conveyor belt can adjust the distance between it and the conveyor roller according to actual needs, thereby better adapting to the conveying needs of cartons with different stacking thicknesses and improving the applicability of the device.

[0010] Preferably, the pressing mechanism further includes a plurality of screw rods arranged vertically, the first ends of the plurality of screw rods are rotatably connected to the lifting bracket, and the second ends of the plurality of screw rods are threadedly connected to the frame.

[0011] By adopting the above technical solution, the lifting bracket is driven to rise and fall precisely by rotating the screw rod. At the same time, the screw rod structure can provide stable supporting force to ensure the stable operation of the conveyor belt at different heights, thereby effectively pressing the carton.

[0012] Preferably, a first driven gear is threadedly provided at the second end of the screw rod, the first driven gear is rotatably connected to the frame, and a plurality of the first driven gears are connected by a chain.

[0013] By adopting the above technical solution, by driving a first driven gear and cooperating with the chain, the synchronous rotation and lifting adjustment of multiple screw rods are achieved, thereby ensuring that the lifting bracket remains horizontal during the lifting process and improving the stability of the holding mechanism.

[0014] Preferably, the pressing mechanism further comprises a plurality of guide rods arranged vertically, wherein one end of each of the guide rods is connected to the lifting bracket and the other end is slidably connected to the frame.

[0015] By adopting the above technical solution, the setting of the guide rod can effectively improve the stability of the lifting bracket during the lifting process, and prevent it from tilting or shaking during the lifting process.

[0016] Preferably, a transition roller, a first correcting roller and a second correcting roller are provided between each two adjacent conveying rollers; the transition roller is arranged along the width direction of the frame and is also arranged opposite to the conveyor belt; the first correcting roller and the second correcting roller are both arranged vertically, and the first correcting roller and the second correcting roller are respectively located at the two ends of the transition roller in the length direction and the two ends of the conveyor belt in the width direction; the first correcting roller and the second correcting roller are both slidably connected to the frame in the width direction of the frame.

[0017] By adopting the above technical solution, when conveying stacks of cartons, the first and second correcting rollers approach each other and clamp the stack of cartons, ensuring that the edges of the stacked cartons are aligned vertically across the width of the frame and do not deviate laterally. Due to the presence of the first and second correcting rollers, a large gap exists between adjacent conveyor rollers. To prevent cartons from sliding downward into the gap between the two conveyor rollers during conveyance, the transition roller fills the gap between the two adjacent conveyor rollers, allowing cartons to smoothly transition from the upstream conveyor roller to the downstream conveyor roller. The conveyor rollers, in conjunction with the transition roller, can thus smoothly convey stacks of cartons.

[0018] Preferably, a first side bracket is provided below or above the conveying roller, and the first side bracket is slidably connected to the frame in the width direction of the frame; the first ends of the plurality of first deviation-correcting rollers are rotatably connected to the first side bracket.

[0019] By adopting the above technical solution, the provision of the first side bracket enables the centralized installation of multiple first deviation-correcting rollers, and through the sliding connection with the frame in the width direction, the adjustability of the overall structure in the width direction is achieved.

[0020] Preferably, a second side bracket is provided below or above the conveying roller, and the second side bracket is slidably connected to the frame in the width direction of the frame; the first ends of the plurality of second deviation-correcting rollers are rotatably connected to the second side bracket.

[0021] By adopting the above technical solution, the provision of the second side bracket enables the centralized installation of multiple second deviation-correcting rollers, and through the sliding connection with the frame in the width direction, the adjustability of the overall structure in the width direction is achieved.

[0022] Preferably, a third side bracket is provided on a side of the second side bracket away from the first side bracket; the third side bracket is slidably connected to the frame in the width direction of the frame, and is connected to the second side bracket via an elastic member.

[0023] By adopting the above technical solution, the third side bracket is driven to bring the second side bracket closer to the carton, thereby causing the multiple second correcting rollers to press against one side of the carton. The elastic member enables the first and second correcting rollers to elastically clamp the stacked cartons, preventing them from being damaged.

[0024] Preferably, a vibrator is provided at one end of the third side bracket away from the first side bracket, and the vibrator is connected to the frame via a telescopic member provided along the width direction of the frame.

[0025] By adopting the above technical solution, after the position of the first correcting roller is adjusted, the telescopic member extends, causing the third side bracket to push the second side bracket and the second correcting roller toward the first correcting roller. The elastic member, the first correcting roller, and the second correcting roller cooperate to elastically clamp the stack of cartons. When correcting the stack of cartons, the vibrator vibrates across the width of the frame, causing the stack to vibrate and gradually align the edges of the stacked cartons across the width of the frame, achieving stable and damage-free correction of the stack of cartons.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. In the present application, the cooperation between the conveyor roller and the conveyor belt can clamp and convey the stacked cartons, so that the stacked cartons can be conveyed to the downstream in a stable and non-deflecting manner.

[0027] 2. In the present application, when conveying stacks of cartons, the first and second correcting rollers are close to each other to clamp the stacks of cartons, so that the edges of the stacks of cartons are flush on the vertical plane in the width direction of the frame and will not deviate to the side.

[0028] 3. In this application, due to the presence of the first and second deflection-correcting rollers, there is a large gap between the two adjacent conveyor rollers. In order to prevent the carton from being inserted into the gap between the two conveyor rollers during conveyance, the transition roller plays the role of filling the gap between the two adjacent conveyor rollers, so that the carton can smoothly transition from the upstream conveyor roller to the downstream conveyor roller, and the conveyor roller and the transition roller can smoothly convey stacks of cartons.

[0029] 4. In the present application, when correcting the stacks of cartons, the vibrator vibrates in the width direction of the frame, thereby shaking the stacks of cartons, and gradually shakes and aligns the edges of the stacks of cartons in the width direction of the frame, so as to achieve stable and damage-free correction of the stacks of cartons.

[0033] The following is combined with Figure 1-2 This application is described in further detail.

[0034] The embodiment of the present application discloses a carton production line connection and conveying device.

[0035] Reference Figure 1 and Figure 2 A carton production line connecting conveying device includes a frame 1, a conveying mechanism 2 and a holding mechanism 3. The conveying mechanism 2 includes a plurality of conveying rollers 21. The conveying rollers 21 are arranged along the width direction of the frame 1, and the plurality of conveying rollers 21 are evenly distributed in the length direction of the frame 1. The holding mechanism 3 includes a conveyor belt 32. The conveyor belt 32 is arranged along the length direction of the frame 1 and is installed above the conveying rollers 21 in a liftable manner. Specifically, the holding mechanism 3 also includes a lifting bracket 31. The lifting bracket 31 is installed on the frame 1 on the conveying rollers 21 in a liftable manner. The conveyor belt 32 is installed on the lifting bracket 31. By adjusting the height of the lifting bracket 31, the distance between the conveyor belt 32 and the conveying rollers 21 can be adjusted according to actual needs, so as to better adapt to the conveying needs of cartons with different stacking thicknesses, thereby improving the applicability of the device.

[0036] Reference Figure 1 and Figure 2 In the embodiment of the present application, stacks of cartons are placed on the conveyor rollers 21, and the conveyor belt 32 descends to press the stacks of cartons against the conveyor rollers 21. When conveying the stacks of cartons, the conveyor rollers 21 and the conveyor belt 32 operate synchronously to transport the stacks of cartons downstream. In summary, through the coordinated cooperation of the conveyor rollers 21 and the conveyor belt 32, the stacks of cartons can be clamped and transported, allowing the stacks of cartons to be transported stably and without deviation to the downstream.

[0037] Reference Figure 1 and Figure 2The holding mechanism 3 further includes a plurality of vertically arranged screw rods 33. The first ends of the plurality of screw rods 33 are rotatably connected to the lifting bracket 31, and the second ends of the plurality of screw rods 33 are threadedly connected to the frame 1. In the embodiment of the present application, the lifting bracket 31 is precisely raised and lowered by rotating the screw rods 33. At the same time, the screw rods 33 structure can provide stable support force, ensuring the stable operation of the conveyor belt 32 at different heights, thereby effectively holding the carton.

[0038] Reference Figure 1 and Figure 2 The second end of the screw rod 33 is provided with a first driven gear 34 that is screwed, and the first driven gear 34 is rotatably connected to the frame 1. The multiple first driven gears 34 are connected by a chain 37. Specifically, a coaxial second driven gear 340 is provided on a first driven gear 34, and a meshing driving gear 36 is provided on the side of the second driven gear 340. A servo motor 35 is connected between the driving gear 36 and the frame 1. The driving gear 36 is driven to rotate by the servo motor 35, thereby driving the second driven gear 340 to rotate, and then driving the first driven gear 34 to rotate. The first driven gear 34 is combined with the chain 37 to drive the multiple screw rods 33 to rotate synchronously. In the embodiment of the present application, by driving a first driven gear 34 and cooperating with the chain 37, the synchronous rotation and lifting adjustment of the multiple screw rods 33 are achieved, thereby ensuring that the lifting bracket 31 remains horizontal during the lifting process and improving the stability of the holding mechanism 3.

[0039] Reference Figure 1 and Figure 2 The holding mechanism 3 further includes a plurality of vertically arranged guide rods 38, each of which is connected to the lifting bracket 31 at one end and slidably connected to the frame 1 at the other end. Specifically, the guide rods 38 are sleeved with linear bearings 39 mounted on the frame 1. In the embodiment of the present application, the provision of the guide rods 38 can effectively improve the stability of the lifting bracket 31 during the lifting process, preventing it from tilting or shaking during the lifting process.

[0040] Reference Figure 1 and Figure 2 Between each pair of adjacent conveyor rollers 21, a transition roller 22, a first correcting roller 4, and a second correcting roller 5 are provided. The transition roller 22 is arranged along the width of the frame 1 and is also arranged opposite the conveyor belt 32. The first correcting roller 4 and the second correcting roller 5 are both arranged vertically, and are located at both ends of the transition roller 22 in the longitudinal direction and the conveyor belt 32 in the width direction, respectively. The first correcting roller 4 and the second correcting roller 5 are both slidably connected to the frame 1 in the width direction.

[0041] Reference Figure 1 and Figure 2In the embodiment of the present application, when conveying stacks of cartons, the first deflection-correcting roller 4 and the second deflection-correcting roller 5 are close to each other and clamp the stack of cartons, so that the edges of the stack of cartons can be flush on the vertical plane in the width direction of the frame 1 and will not deviate to the side. Due to the presence of the first deflection-correcting roller 4 and the second deflection-correcting roller 5, there is a large gap between two adjacent conveying rollers 21. In order to prevent the carton from sliding down into the gap between the two conveying rollers 21 during conveying, the transition roller 22 plays the role of filling the gap between the two adjacent conveying rollers 21, so that the carton can smoothly transition from the upstream conveying roller 21 to the downstream conveying roller 21, so that the conveying roller 21 and the transition roller 22 can smoothly convey the stack of cartons.

[0042] Reference Figure 1 and Figure 2 A first side bracket 41 is provided below or above the conveyor roller 21 and is slidably connected to the frame 1 in the width direction of the frame 1. The first ends of the plurality of first deflection-correcting rollers 4 are rotatably connected to the first side bracket 41. In the embodiment of the present application, the provision of the first side bracket 41 enables the plurality of first deflection-correcting rollers 4 to be centrally mounted, and through the sliding connection with the frame 1 in the width direction, the overall structure is adjustable in the width direction.

[0043] Reference Figure 1 and Figure 2 A second side bracket 51 is provided below or above the conveyor roller 21. The second side bracket 51 is slidably connected to the frame 1 in the width direction of the frame 1. The first ends of the plurality of second deflection-correcting rollers 5 are rotatably connected to the second side bracket 51. In the embodiment of the present application, the provision of the second side bracket 51 enables the plurality of second deflection-correcting rollers 5 to be centrally installed, and through the sliding connection with the frame 1 in the width direction, the overall structure is adjustable in the width direction.

[0044] Reference Figure 1 and Figure 2 A third side bracket 53 is provided on the side of the second side bracket 51 away from the first side bracket 41. The third side bracket 53 is slidably connected to the frame 1 in the width direction of the frame 1 and is connected to the second side bracket 51 via an elastic member 52. In the embodiment of the present application, by driving the third side bracket 53, the second side bracket 51 is brought closer to the carton, thereby causing the multiple second correcting rollers 5 to press against one side of the carton. The elastic member 52 enables the first correcting rollers 4 and the second correcting rollers 5 to elastically clamp the stacked cartons, preventing them from being damaged by being pinched.

[0045] Reference Figure 1 and Figure 2, a vibrator 54 is provided at one end of the third side bracket 53 away from the first side bracket 41, and the vibrator 54 is connected to the frame 1 by a telescopic member 55 arranged along the width direction of the frame 1. In the embodiment of the present application, after the position adjustment of the first correcting roller 4 is completed, the telescopic member 55 is extended to cause the third side bracket 53 to push the second side bracket 51 and the second correcting roller 5 toward the first correcting roller 4, and the elastic member 52, the first correcting roller 4, and the second correcting roller 5 cooperate to elastically clamp the stacked cartons. When correcting the deviation of the stacked cartons, the vibrator 54 vibrates in the width direction of the frame 1, thereby causing the stacked cartons to shake, and in the width direction of the frame 1, the edges of the stacked cartons are gradually shaken and aligned, so as to achieve stable and damage-free correction of the stacked cartons.

[0046] The implementation principle of the carton production line connection conveyor device in the embodiment of the present application is as follows: The stack of cartons is placed on the conveying roller 21 between the first correcting roller 4 and the second correcting roller 5. The first correcting roller 4 and the second correcting roller 5 are close to each other, and cooperate with the elastic member 52 to elastically clamp the stack of cartons.

[0047] Due to the limited strength of cartons, it is easy to damage some cartons when clamping and aligning the stacked cartons at one time. Therefore, when correcting the stacked cartons, the vibrator 54 vibrates in the width direction of the frame 1, thereby shaking the stacked cartons. In the width direction of the frame 1, the edges of the stacked cartons are gradually shaken and aligned. In conjunction with the elastic member 52, stable and damage-free correction of the stacked cartons can be achieved.

[0048] After the stack of cartons has been corrected and aligned, the vibrator 54 is turned off, maintaining the elastic gripping state of the first and second correcting rollers 4 and 5. The conveyor belt 32 descends, pressing the stack of cartons against the conveyor rollers 21. During the conveying of the stack of cartons, the conveyor rollers 21 and the conveyor belt 32 operate synchronously, gripping and conveying the stack of cartons, ensuring that the stack of cartons can be stably and non-deflectedly conveyed downstream.
