Description

Technical Field

[0001] The utility model relates to the field of feeding equipment, in particular to a feeding machine capable of flexibly adjusting a feeding width. Background Art

[0002] With the development of production automation technology, the use of feeders for automatic feeding of production lines has gradually become the mainstream mode. Due to the wide variety of packaging box products produced by the company, the length, width and thickness of the materials are different. The existing material bottom-drawing feeder uses a full-width belt line for feeding. Two guide strips are relatively installed above the belt line along its width direction to guide the material. The installation spacing between the two guide strips can be adjusted according to the material width to achieve the purpose of adjusting the feeding width. However, since the lower edge of the guide strip does not contact the upper surface of the belt line, there must be a gap between the two. When the material is a very thin facial paper, the material will be stuck in the gap between the guide strip and the belt line, which will not only damage the material until the material is scrapped, but also cause the feeder to be stuck and unable to be used, affecting production efficiency. In addition, when the feeder discharges the material to a wide belt line, the spacing between adjacent continuous materials is too small (that is, the two adjacent materials are close to each other), and there will be certain interference between the materials when the subsequent process equipment uses the material, which affects the use of the subsequent process equipment.

[0040] Please refer to Figures 1 to 8A feeding machine with flexible adjustment of feeding width provided in an embodiment of the present application comprises: a frame 17, a conveyor belt and a feeding guide rail 5; the conveyor belt is arranged on the frame 17, and the conveyor belt comprises a plurality of sheet-base belts 6 located in the same horizontal plane and running synchronously, the plurality of sheet-base belts 6 are arranged in parallel and spaced apart in the width direction, and the positions of the plurality of sheet-base belts 6 in the width direction are adjustable to change the width of the conveyor belt; the two feeding guide rails 5 are arranged in parallel and connected to the frame 17, the two feeding guide rails 5 are respectively located on both sides of the conveyor belt in the width direction, and the spacing distance between the two feeding guide rails 5 can be adjusted as the width of the conveyor belt changes.

[0041] It should be noted that the existing material pull-down loader uses a wide conveyor belt. When the material width becomes smaller, the distance between the two guide bars needs to be reduced. Since the guide bar is located above the conveyor belt at this time, in order to avoid particle loss due to contact and friction between the lower edge of the guide bar and the conveyor belt surface, a certain gap is usually left between the lower edge of the guide bar and the conveyor belt surface. When the material is very thin tissue paper, the material will be stuck between the guide bar and the conveyor belt.

[0042] In the embodiment of the present application, since multiple sheet base belts 6 are arranged at intervals, the width of the conveyor belt refers to the distance between the outer sides of the two outermost sheet base belts 6. The two feeding guide rails 5 are respectively arranged on the outer sides of the two outermost sheet base belts 6. When the width of the material 4 changes, the position of each sheet base belt 6 is adjusted to change the spacing, thereby changing the width of the conveyor belt, and at the same time adjusting the position of the two feeding guide rails 5 to adapt to the width of the material. Of course, the left and right feeding guide rails 5 can also be installed on both sides of different sheet base belts 6 according to the width of the material 4 to achieve the purpose of flexibly adjusting the feeding width. Because the feeding guide rails 5 are on the side of the sheet base belt 6, no material will be stuck, solving the problem of stuck materials affecting production efficiency and waste materials.

[0043] The embodiment of the present application divides the conveyor belt into multiple flat belts and arranges feeding guide rails on both sides of the conveyor belt. Since the flat belts and the feeding guide rails are adjustable along the width direction of the conveyor belt, the positions can be flexibly adjusted according to the width of the material size, so that the feeding machine can meet the needs of materials of different widths. Since the feeding guide rails are never above the conveyor belt, the material will not be stuck between the feeding guide rails and the conveyor belt.

[0044] According to some embodiments of the present application, the frame 17 includes a base 171 and two opposite side panels 172 arranged on the upper part of the base 171, and the conveyor belt is installed between the two side panels 172. The conveyor belt also includes a driving roller 12 and a driven roller 19, and the two ends of the driving roller 12 and the driven roller 19 are installed on the two side panels 172 on the frame 17, and the driving roller 12 is driven to rotate by the driving roller motor 14. Among them, the driving roller 12 is located at the unloading end of the conveyor belt, and the driven roller 19 is located at the loading end of the conveyor belt. A plurality of sheet base belts 6 are installed on the driving roller 12 and the driven roller 19, and the sheet base belts 6 are driven to rotate by the rotation of the driving roller 12. A plurality of groups of limiting rings 7 are arranged on the driven roller 19, and the two limiting rings 7 of each group are respectively fixed to the two sides of the sheet base belt 6 by screws to limit the position of the sheet base belt. When adjusting the position of the sheet base belt 6, loosen the fixing screws of the limit ring 7, adjust the left and right positions of the sheet base belt 6, make the material fall on a reasonable position of the sheet base belt, and then fix the limit ring. This reasonable position is that the friction force of the sheet base belt on both sides of the material is balanced, and the material can be discharged smoothly without deviation.

[0045] According to some embodiments of the present application, two connecting rods 10 are arranged between the two side plates 172 of the frame 17 along the width direction of the conveyor belt, and the feeding guide rail 5 is connected to the two connecting rods 10 through two connecting seats 18. Specifically, the connecting seat 18 is an inverted T-shaped structure, the lower end of which is fixedly connected to the feeding guide rail 5, and the upper part is provided with a through hole adapted to the connecting rod 10, and the connecting rod 10 is inserted into the through hole of the connecting seat 18 during installation. The feeding guide rail 5 is installed on the connecting rod 10 by hanging, and a gap is left between the lower edge of the feeding guide rail 5 and the table 173 (on the frame 17 and located on the lower side of the upper belt body of the conveyor belt to support each base belt 6).

[0046] According to some embodiments of the present application, in order to facilitate locking the position of the connection seat on the connection rod, a slit that penetrates the through hole is opened on the top of the connection seat, so that the distance between the two halves of the upper part of the connection seat can be adjusted by screws (even if the width of the slit changes), so that the connection seat can hold or loosen the connection rod. After loosening the connection seat, adjust the position of the left and right feeding guide rails to the side of the sheet base belt and then lock the connection seat. This feeding guide rail plays a role in limiting and guiding the material.

[0047] According to some embodiments of the present application, the feeder also includes a plurality of feed baffle assemblies 9 arranged at intervals along the width direction of the conveyor belt, the feed baffle assemblies 9 are connected to the frame 17 and the position along the width direction is adjustable, and the feed baffle assemblies 9 include a material dividing strip 91, the material dividing strip 91 is arranged vertically above the conveyor belt, and the distance from the lower edge of the material dividing strip to the sheet base belt 6 is adjustable. Since the distance from the lower edge of the material dividing strip to the conveyor belt is adjustable, that is, the position of the material dividing strip can be adjusted up and down, so that the feeder can meet the use of materials of different thicknesses. When in use, the distance from the lower end of the material dividing strip 91 to the surface of the sheet base belt 6 is adjusted according to the thickness of the material, so that when the sheet base belt rotates, a material located at the bottom layer is pumped between the lower end of the material dividing strip and the sheet base belt, and then conveyed with the sheet base belt. In order to facilitate the material to enter the gap between the lower end of the material dividing strip and the sheet base belt, a guide slope is provided on the side of the material dividing strip facing the material, and the guide slope extends to the lower end of the material dividing strip.

[0048] According to some embodiments of the present application, the feeding baffle assembly 9 also includes a fixed bottom plate 92 and a guide bar 93 arranged on the fixed bottom plate 92, the guide bar 93 has a guide groove vertically opened on the upper edge, the dividing strip 91 is arranged in the guide groove, and an L-shaped mounting sheet metal 94 is arranged on the dividing strip 91, the mounting sheet metal 94 is connected to the upper end of the guide bar 93 through an adjusting screw 95, and a compression spring 96 is sleeved on the adjusting screw 95, and the upper and lower ends of the compression spring 96 are respectively abutted between the mounting sheet metal 94 and the guide bar 93. In this example, there are three feeding baffle assemblies 9, and there are three dividing strips arranged along the width direction of the conveyor belt, wherein the fixed bottom plates 92 corresponding to the dividing strips 91 on the left and right sides are fixedly connected to the feeding guide rail 5, and can adjust the position synchronously with the feeding guide rail 5; the fixed bottom plate 92 corresponding to the middle dividing strip 91 is fixedly connected to the clamping plate 112. When in use, adjust the height of the dividing strip according to the thickness of the material, so that the vertical height between the dividing strip and the base belt can just allow one material to pass through. The loading baffle assembly plays a role in dividing the materials, and can only discharge one material at a time to prevent the material from overlapping and discharging more than one material at a time.

[0049] According to some embodiments of the present application, a feeding sheet metal 8 is provided on each of the feeding guide rails 5, and the feeding sheet metal 8 is located in front of the feeding baffle assembly 9, and the feeding sheet metal 8 extends vertically and its inner side edge is flush with the inner side edge of the feeding guide rail 5. That is, two feeding sheet metals 8 are arranged relatively at the inner edge of the feeding guide rail 5, and the feeding sheet metals on the left and right sides increase the temporary storage space for materials, so that more materials can be loaded at one time, for example, multiple cardboards can be stacked between the two feeding sheet metals.

[0050] According to some embodiments of the present application, a longitudinal pressing roller assembly 11 is provided on the frame 17, and the longitudinal pressing roller assembly 11 is located behind the loading baffle assembly 9. The longitudinal pressing roller assembly 11 includes a plurality of longitudinal pressing rollers 111 arranged at intervals along the conveying direction, and the longitudinal pressing rollers 111 are rotatably installed above the conveyor belt, and their rotation axis is along the width direction of the conveyor belt, and the distance of the longitudinal pressing rollers 111 relative to the conveyor belt can be automatically adjusted. By providing a longitudinal pressing roller assembly after the material strip position, the material can be pressed to prevent it from deviating, and the friction between the material and the sheet base belt can be increased to prevent the thin material from slipping due to insufficient friction.

[0051] According to some embodiments of the present application, the longitudinal pressing roller assembly 11 also includes a pressing plate 112 and a plurality of pressing sheets 113 arranged on the pressing plate 112, the pressing plate 112 is connected to the frame 17 and is arranged parallel to the conveyor belt, the pressing plate 112 is provided with a notch for arranging the longitudinal pressing roller 111, the position of the pressing sheet metal 113 corresponds to the longitudinal pressing roller 111, and roller mounting plates 114 are connected to both ends of the longitudinal pressing roller 111, a suspension rod 115 is slidably arranged on the pressing sheet metal 113, the lower end of the suspension rod 115 is fixedly connected to the roller mounting plate 114, a compression spring 116 is sleeved on the suspension rod 115, and the two ends of the compression spring 116 are respectively abutted between the pressing sheet metal 113 and the roller mounting plate 114. Specifically, both ends of the pressing plate 112 are respectively mounted on the connecting rod 10 through the connecting seat 18, and the pressing sheet metal 113 can be in an inverted U shape, with its lower end straddling the two sides of the notch of the pressing plate 112. Since the compression spring makes the longitudinal pressing roller in an upward and downward movable state, materials of different thicknesses can pass through the longitudinal pressing roller assembly smoothly. The longitudinal pressing roller assembly presses the material to not only prevent the material from running off, but also increase the friction between the material and the base belt to prevent the thin material from slipping due to insufficient friction.

[0052] According to some embodiments of the present application, an acceleration roller 13 is provided on the frame 17, and the acceleration roller 13 is located behind the discharge end of the conveyor belt, and the acceleration roller 13 is flush with the height of the conveyor belt, and the rotation speed of the acceleration roller 13 is greater than the rotation speed of the conveyor belt. Specifically, a group of acceleration rollers 13 is added next to the active roller 12 of the conveyor belt, that is, at the end of the loader. The acceleration rollers 13 are the same size and flush with the active roller 12. The acceleration rollers 13 are driven by the acceleration roller motor 15 to rotate in the same direction as the active roller 12. Since the rotation speed of the acceleration roller 13 is greater than that of the active roller 12, the distance between adjacent continuous materials can be pulled apart, which plays a role in differential material separation, and avoids the influence of efficiency due to the interference of materials when the materials are used by the subsequent process equipment.

[0053] According to some embodiments of the present application, a transverse pressing roller assembly 16 is disposed above the acceleration roller 13, and the transverse pressing roller assembly 16 includes a plurality of transverse pressing rollers 161 arranged at intervals along the width direction of the conveyor belt, and the transverse pressing roller 161 is rotatably mounted on the frame 17, and its rotation axis is along the axial direction of the acceleration roller 13, and the distance of the transverse pressing roller 161 relative to the acceleration roller 13 can be automatically adjusted. Pressing the material by the transverse pressing roller assembly can not only prevent the material from running off, but also increase the friction between the material and the acceleration roller to prevent the thin and light material from slipping due to insufficient friction and failing to accelerate.

[0054] According to some embodiments of the present application, the transverse pressing roller assembly 16 further includes a hanging plate 162 and a slide bar 163 disposed on the hanging plate 162, the hanging plate 162 is disposed parallel to the top of the acceleration roller 13, the slide bar 163 is slidably connected to a transverse plate 174 disposed on the frame 17 along the width direction of the conveyor belt, the two ends of the transverse pressing roller 161 are connected to the hanging plate 162 through a roller mounting plate 164, a compression spring 165 is sleeved on the slide bar 163, and the two ends of the compression spring 165 are respectively abutted between the transverse plate 174 and the hanging plate 162. Since the compression spring makes the transverse pressing roller in an upward and downward movable state, materials of different thicknesses can pass through the transverse pressing roller assembly smoothly.

[0055] According to some embodiments of the present application, a rear support structure is provided on the frame 17, and the rear support structure is used to support the rear of the material 4 so that it forms an inclined state relative to the conveyor belt. The rear support structure includes a support rod 1 and a support member provided at the end of the support rod 1. The inclination angle of the support rod 1 relative to the conveyor belt is adjustable, and the support member is a bearing 2 or a support rod sheet metal 3. Specifically, the rear support structure is selected according to different materials. The rear support structure has a support rod 1 + bearing 2 structure, or a support rod 1 + support rod sheet metal 3 structure, wherein the support rod 1 + bearing 2 structure is suitable for materials with harder materials and thicker materials, and the support rod 1 + support rod sheet metal 3 structure is suitable for materials with softer materials and thinner materials. Both support structures can adjust their positions according to the size of the material. The rear support structure can raise the rear of the stacked material so that it forms an inclined state relative to the conveyor belt, making it convenient for the material to enter between the lower end of the material distribution strip and the sheet base belt.
