Description

Technical Field

[0001] This utility model relates to the field of material feeding, specifically a material feeding mechanism for packaging box linings. Background Technology

[0002] Vertical cartoning machines are automated packaging equipment widely used in the food, pharmaceutical, daily chemical, and electronics industries. Their main function is to automatically load products (such as bottles, cans, tubes, blister packs, and small bags) into folded cardboard boxes or cardboard trays and then seal them. Their core advantages lie in high speed, high efficiency, and standardization, significantly improving the packaging efficiency and quality of the production line. In the entire workflow of a vertical cartoning machine, the "feeding" stage (i.e., the precise and correct placement of the product into the opened cardboard box) is crucial. The speed, accuracy, and reliability of the feeding process directly determine the overall production efficiency and packaging qualification rate of the machine. With increasing market demand, automation has become an inevitable development trend to improve production efficiency.

[0003] Existing feeding methods, such as manual feeding, horizontal moving gripping automatic feeding, and rotary feeding, can only be installed in one direction. These methods are not suitable for feeding the inner linings inside some cardboard boxes, and the feeding structure must be redesigned for each inner lining of different sizes. Utility Model Content

[0004] To achieve the above objectives, the purpose of this utility model is to provide a rotary automatic lining feeding mechanism that can be used for packaging boxes of different sizes. This utility model provides the following technical solution:

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] See Figure 1-7A feeding mechanism, primarily used for feeding inner linings of packaging boxes, includes a storage component, a forming component, and a pressing component. The storage component includes an adjusting foot cup 1, a frame 2, a fixed base plate 3, a slot box base plate 4, an inner lining baffle 6, a slot support rod 8, a connecting fixing plate 9, an adjusting clamping block 10, an adjusting rod 11, a slot adjusting plate 12, a sliding strip 13, and a gravity pressing block 14. The adjusting foot cup 1 is installed at the bottom of the frame 2 and can adjust the height of the entire mechanism according to different box sizes. The slot box base plate 4 is installed on the fixed base plate 3 and has elongated holes to adjust the front-back direction of the storage component, allowing for adjustment and debugging according to different product sizes. The fixed base plate 3 is equipped with a fixed support 5 and a module support rod. There are two module support rods 31 and four box slot support rods 8, which are symmetrically installed on the left and right sides of the fixed base plate 3. Adjusting clamping blocks 10 are installed on the box slot support rods 8. Connecting fixing plates 9 are connected to the two adjusting clamping blocks 10 on the same side. When the module support rods 31, adjusting clamping blocks 10 and connecting fixing plates 9 are assembled into one unit, the connecting fixing plates 9 can move up and down in the box slot support rods 8 to achieve adjustment and positioning. Adjusting rods 11 are installed on adjusting clamping blocks 10. Paper slot adjusting plates 12 are connected to adjusting rods 11. When the adjusting rods 11, adjusting clamping blocks 10 and paper slot adjusting plates 12 are assembled into one unit, adjusting the paper slot adjusting plates 12 can move left and right in the adjusting rods 11. To achieve adjustment and positioning, the paper slot adjustment plate 12 is equipped with an inner liner baffle 6, a slide bar 13, and a gravity block 14. Since the supporting surface of the paper slot adjustment plate 12 is inclined, under the action of the gravity block 14, the inner liner cardboard 47 gathers in the inclined direction. The inner liner baffle 6 blocks the inner liner cardboard 47 and positions it on the end face of the paper slot adjustment plate 12. The forming components include an adjustment base plate 15, a drive shaft support seat 16, a drive shaft 17, a suction cup seat connecting plate 18, a front guide block 21, a guide adjustment plate 22, a rear guide block 23, a guide plate 24, a suction cup seat 25, a clamping block 26, a cylinder positioning plate 27, a rotary cylinder 28, a flange 29, and a vacuum suction cup 30. The adjustment base plate 15 and the clamping block 26 are both mounted on the module support rod. The clamping block 26 is loosened and tightened. The adjustable base plate 15 can move up and down on the module support rod 31 to achieve adjustment and positioning. The guide adjustment plate 22 is installed on the adjustable base plate 15 and is connected to the guide plate 24. The width of the two guide adjustment plates 22 can be adjusted according to the size of the inner lining cardboard 47. A front guide block 21 is installed on the adjustable base plate 15 and a rear guide block 23 that cooperates with the front guide block 21 is installed on the guide adjustment plate 22 to guide the inner lining cardboard 47. The rear guide block 23 can be adjusted back and forth on the guide adjustment plate 22 to adapt to different sizes of inner lining cardboard 47. The rotary cylinder 28 is installed on the cylinder positioning plate 27 and is connected to the drive shaft 17 and the drive shaft support seat 16 respectively through the flange 29.The vacuum suction cup 30 is fixed on the drive shaft 17 and is connected to the suction cup base 25 and the suction cup base connecting plate 18 respectively.

The module adjusting block 32 is installed on the module support rod 31 and is connected to the module fixing plate 33. The module fixing plate 33 is connected to the linear module 34, the module connecting plate 35, the cylinder fixing plate 36, and the TCL three-axis cylinder 37 respectively. Plate 38 is mounted on TCL three-axis cylinder 37, and cylinder connecting plate 38 is connected to cylinder support plate 39. The pressing component is connected to cylinder support plate 39. The pressing component includes cylinder adjusting plate 40, MA cylinder 41, linear guide rail 42, floating joint 43, cylinder connecting block 44, cylinder push rod 45, paper box pressing block 46, and vacuum suction cup 30. The component connected to module adjusting block 32 can move up and down on module support rod 31 to adjust the height, allowing adjustment according to different box sizes. TCL three-axis cylinder 37 is connected to the pressing component, ensuring the pressing component does not wobble during operation and providing greater stability during pressing. Cylinder adjusting plate 40 can be adjusted up and down on cylinder support plate 39 to adjust the depth of pressing. Cylinder push rod 45 is connected to linear guide rail 42, making the movement of cylinder push rod 45 smoother.

[0032] The aforementioned structure's storage component is adjustable to accommodate different inner linerboard sizes, enabling storage adaptation for inner linerboards of varying widths and lengths.

[0033] Height adjustment: Adjustable feet are installed at the bottom of the frame, which can adjust the height of the entire mechanism according to different cardboard box sizes to meet the height requirements of different material feeding scenarios;

[0034] Front and rear adjustment: The bottom plate of the slot box is installed on the fixed base plate, and the bottom plate of the slot box is provided with an elongated hole to adjust the front and rear position of the storage component to accommodate the length difference of the inner lining cardboard.

[0035] Width adjustment: The box slot support rods are symmetrically installed on both sides of the fixed base plate. The adjusting clamping block is installed on the box slot support rod. The paper slot adjusting plate is connected to the adjusting clamping block through the adjusting rod. The adjusting rod can drive the paper slot adjusting plate to move left and right, thereby adjusting the width of the storage area to adapt to different widths of inner lining paperboard.

[0036] Positioning aid: The support surface of the paper trough adjustment plate is inclined. The gravity block can push the inner liner paperboard to gather in the inclined direction. The inner liner baffle (with an inner liner limiting plate that can be added) further positions the paperboard, ensuring that paperboards of different sizes can be stored stably.

[0037] In one embodiment of this utility model, the cylinder adjusting plate 40 is connected to the MA cylinder 41 and installed on the cylinder support plate 39. The MA cylinder 41 is connected to the cylinder push rod 45 through a movable joint and a cylinder connecting block. The cylinder push rod 45 is connected to the paper box pressing block 46 and the vacuum suction cup 30 respectively. The linear guide rail 42 is installed on the cylinder support plate 39 and connected to the cylinder push rod 45, resulting in better overall performance.

[0038] In one embodiment of this utility model, the TCL three-axis cylinder 37 is mounted on the cylinder fixing plate 36 and connected to the module connecting plate 35 through the cylinder fixing plate 36, making it more stable during operation.

[0039] In one embodiment of this utility model, the bottom of the slot support rod 8 is mounted on the slot bottom plate 4 by a fixed support 5, which provides a strong connection and prevents it from easily coming loose.

[0040] In one embodiment of this utility model, the front guide block 21 is installed on the adjusting base plate 15 by means of the guide block support plate 19 and the guide block positioning post 20, which provides stronger support and thus ensures the guiding effect.

[0041] In one embodiment of this utility model, an inner lining limiting plate 7 is installed on the inner lining baffle 6, which can limit the inner lining cardboard 47.

[0042] Its forming component's suction cup and guide structure are adjustable to adapt to the positioning and transfer of different cardboards. The forming component allows for flexible adjustment of the suction cup position and guide width, accommodating the adsorption and pre-folding of cardboards of different sizes.

[0043] Height adjustment: The adjusting base plate and clamping block are mounted on the module support rod. Loosening or tightening the clamping block can move the adjusting base plate up and down, adjusting the overall height of the molding part to match the adsorption height of different sized cardboard.

[0044] Width and guide adjustment: The guide adjustment plate is mounted on the adjustment base plate and connected to the guide plate. The distance between the two guide adjustment plates can be adjusted according to the size of the inner lining cardboard. The rear guide block is mounted on the guide adjustment plate and can move back and forth. Together with the front guide block (mounted on the adjustment base plate through the guide block support plate and positioning post), it can achieve precise guidance of cardboard of different sizes.

[0045] Suction cup adaptation and adjustment: The vacuum suction cup is fixed on the drive shaft, which is driven by a rotary cylinder and flange. The orientation of the suction cup can be changed by adjusting the installation direction of the suction cup seat and the suction cup seat connecting plate. The width of the hopper can be indirectly changed by adjusting the position of the suction cup. There is no need to redesign due to changes in the length and width of the product. It is suitable for the adsorption and transfer of various sizes of cardboard.

[0046] Pressing component: Height and pressing depth are adjustable to fit different box sizes.

[0047] Height adjustment: The module adjustment block is mounted on the module support rod and connected to the module fixing plate. The module fixing plate is associated with components such as the linear module and TCL three-axis cylinder. Loosening the module adjustment block can drive the pressing component to move up and down as a whole to adapt to product boxes of different heights.

[0048] Pressing depth adjustment: The cylinder adjustment plate is mounted on the cylinder support plate and can move up and down. It connects the MA cylinder and the cylinder push rod. By adjusting the position of the cylinder adjustment plate, the pressing depth of the MA cylinder can be changed, ensuring that boxes of different depths can be pressed into place.

[0049] Stability Guarantee: TCL's three-axis cylinder connects to the pressing component, preventing overall wobbling during pressing; the cylinder push rod is connected to the linear guide rail, ensuring smooth pressing motion and adapting to the stable pressing requirements of boxes of different sizes.

[0050] The above-described structure enables the automatic feeding mechanism for the inner lining of this packaging box to achieve multiple adjustable structures through three major components: material storage, forming, and pressing. This allows for an automated feeding process combining adsorption, pre-folding, and pressing, achieving multi-size product adaptation and efficient automatic feeding. The specific implementation sequence is as follows, which also represents the fundamental principle of this product:

[0051] 1. First, place the inner lining cardboard 47 into the slot of the storage component and lower the gravity block 14. Under the pushing force of the gravity block 14, the inner lining cardboard 47 is gathered towards the end face of the paper slot adjusting plate 12. Then, adjust the left-right width and front-back width of the paper slot adjusting plate 12 according to the width of the inner lining cardboard 47 to form an inner lining cavity (see...). Figure 3 Finally, adjust the pressing height of the pressing component and the material removal travel distance.

[0052] 2. The suction cup base 25 is horizontal in the initial position of the rotary cylinder 28. When the rotary cylinder 28 works, the vacuum suction cup 30 swings upward. The vacuum suction cup 30 is ventilated and works. After swinging to the positioning position of the storage component, the surface of the vacuum suction cup 30 is attached to one side of the inner lining cardboard 47. Because the vacuum suction cup 30 is attached to the inner lining cardboard 47, a vacuum is formed inside the vacuum suction cup 30, thus firmly adsorbing the inner lining cardboard 47 onto the vacuum suction cup 30. At this time, the PLC detects the positioning position of the vacuum suction cup 30 to the storage component through the photoelectric sensor and sends a command to make the rotary cylinder 28 reverse the movement until the vacuum suction cup 30 swings downward back to the initial position. Then the vacuum suction cup 30 stops supplying air, and the rotary cylinder 28 stops swinging (see...). Figure 4 ).

[0053] 3. When the inner linerboard 47 is sucked into the initial position of the rotary cylinder 28, under the action of the adjusted forming cavity of the guide plate 24, the small plane of the inner linerboard 47 is folded 90°, forming a pre-fold of the inner linerboard (see...). Figure 5At this point, the linear module 34, positioned above the inner lining mold cavity, quickly moves the pressing component above the predetermined inner lining. Then, the TCL three-axis cylinder 37 extends, causing the pressing component to move downwards. The vacuum suction cup 30 of the pressing component begins to supply air. When the vacuum suction cup 30 is in contact with the bottom surface of the inner lining cardboard 47, the vacuum suction cup 30 holds the inner lining cardboard 47, and the linear module 34 drags the inner lining cardboard 47 above the inner lining mold cavity (see...). Figure 6 The MA cylinder 41 pushes the cylinder push rod 45 and the cardboard box pressing block 46 downwards. When the cardboard box pressing block 46 presses the inner lining cardboard 47 into the inner lining mold cavity, the vacuum suction cup 30 stops working. At this time, under the guidance and limiting action of the inner lining mold cavity, the four sides of the inner lining cardboard 47 are folded, becoming a five-sided closed inner lining cardboard box, which is then pressed down by the cardboard box pressing block 46, passing through the inner lining mold cavity and into the product box (see...). Figure 7 When the cardboard box pressing block 46 reaches the lower limit, the TCL three-axis cylinder 37 and the MA cylinder 41 retract upwards simultaneously until they return to their initial positions. This is the entire process from the material storage component placing the inner linerboard 47 to the forming component absorbing and transferring the material, and then to the pressing component absorbing and pressing the material into the box. When the above process is repeated continuously, continuous and rapid automatic feeding can be achieved.

[0054] It should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "fixed," "set," etc., should be interpreted broadly. For example, they can refer to welded connections, bolted connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
