Description

Technical Field

[0001] This utility model relates to the field of food packaging machinery technology, specifically to an automatic feeding device for food packaging. Background Technology

[0002] For stacked packaging materials, such as folded food cartons and plastic packaging shells, automatic feeding equipment for food packaging can control the release of materials one by one and in a quantitative manner, avoiding the inefficiency and material spillage problems of manual handling.

[0003] In the prior art, a conveying device for processing packaging boxes, with patent publication number CN223200433U, includes a workbench, a conveying mechanism installed on the workbench, a feeding plate installed on the conveying mechanism, and a loading and unloading mechanism installed on the feeding plate. The loading and unloading mechanism includes a support plate, which is fixedly connected to one side of the top of the feeding plate. A mounting block is connected to one side of the support plate, and a baffle is hinged to the mounting block by a pin.

[0004] During use, the device requires frequent horizontal reciprocating movement of the moving plate and the feeding plate controlled by a linear motor to ensure precise connection of loading and unloading actions. If the start and stop control of the linear motor is not accurate, the feeding plate will move at different speeds during the conveying process of the same batch of packaging boxes, resulting in uneven spacing between adjacent packaging boxes. This makes it difficult to meet the uniformity requirements of the packaging box spacing in subsequent processing steps. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic feeding device for food packaging, which can effectively solve the problem that if the start and stop control accuracy of the linear motor is not good, the spacing of the packaging boxes in the same batch will be uneven during the transportation process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an automatic feeding device for food packaging, including a conveying mechanism, including a conveyor belt, a mounting frame disposed at the outer end of the conveyor belt, a feeding plate fixedly connected to the outer surface of the mounting frame for feeding packaging boxes, and a fixing rod fixedly connected to the inner wall of the mounting frame for supporting packaging boxes.

[0008] The feeding mechanism includes a pushing component for pushing the packaging boxes at the top of the fixed rod one by one toward the conveyor belt, a distributing component for controlling the packaging boxes in the unloading plate to move one by one to the top of the fixed rod, and a transmission component that can use the rotational power of the pushing component to drive the conveyor belt to operate continuously.

[0009] The pushing component is located inside the mounting frame, the distributing component is located outside the unloading plate, and the transmission component is located between the conveyor belt and the pushing component.

[0010] The pushing assembly includes a rotating rod rotatably connected to the inner surfaces of both sides of the mounting frame, a swing rod fixedly sleeved on the outer surface of the rotating rod, a hinge rod hinged to the other end of the swing rod, a movable rod hinged to the outer surface of the hinge rod, and a plurality of pusher blocks integrally formed on the top of the movable rod for pushing materials.

[0011] Furthermore, the pushing assembly also includes a support rod that is fixedly mounted to the inner wall of the mounting frame via a bearing and used in conjunction with the hinge rod, and a motor that is adapted to be mounted to the outer side of the mounting frame and used in conjunction with the rotating rod.

[0012] Furthermore, the outer end face of the hinge rod is hinged to the outer end face of the support rod;

[0013] The rotating rod, swing rod, hinge rod, and support rod are each provided in two sets to prevent the position of the pusher block from shifting. When one set of the rotating rod, swing rod, hinge rod, and support rod is in operation, it can drive the other set of the rotating rod, swing rod, hinge rod, and support rod to move synchronously through the pusher block.

[0014] Furthermore, the material distribution assembly includes a first helical gear fixedly sleeved on the output end of the motor, a second helical gear meshing with the outside of the first helical gear, a roller fixedly connected to the inner surface of the second helical gear, a guide groove formed on the outer surface of the roller, a force-bearing column movably connected to the inner wall of the guide groove, and a slider fixedly connected to the outer end face of the force-bearing column.

[0015] Furthermore, the material distribution assembly also includes a baffle plate fixedly connected to the outer surface of the slider and used in conjunction with the feeding plate, a positioning rod fixedly connected to the outer surface of the mounting frame and used to support the slider, and a spring sleeved on the outside of the positioning rod.

[0016] Furthermore, the guide groove includes a force-applying groove formed on the outer surface of the roller shaft, and a force-removing groove formed on the other side of the roller shaft.

[0017] Furthermore, the outer end face of the roller is fixedly mounted to the outer surface of the mounting frame via a bearing, the slider is slidably sleeved on the outer surface of the positioning rod, the spring is fixedly connected to the outer surface of the mounting frame, and its other end abuts against the slider, and the two ends of the force application groove and the force release groove are interconnected.

[0018] Furthermore, the transmission assembly includes a belt sleeved on the through end of the rotating rod on the side away from the motor via a pulley, and a transmission column sleeved on the other end of the belt via a pulley for driving the conveyor belt.

[0019] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0020] This invention, by setting up a feeding mechanism, can not only automatically drive the movable rod to move the pusher block to form a periodic elliptical trajectory, so that the pusher block pushes the packaging box on the fixed rod to the surface of the conveyor belt, but also automatically control the baffle plate at the end of the feed plate to open and close at a fixed frequency, so as to ensure that the speed at which multiple packaging boxes slide to the fixed rod remains consistent. This achieves the effect of ensuring that the distance between adjacent packaging boxes on the surface of the conveyor belt is equal, while avoiding the reduction of food processing quality due to the deviation of the packaging box distance.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example: An automatic feeding device for food packaging, see attached figure. Figure 1 - Appendix Figure 7 ,include,

[0033] The conveying mechanism 100 includes a conveyor belt 110, a mounting frame 120 disposed at the outer end of the conveyor belt 110, a feeding plate 130 fixedly connected to the outer surface of the mounting frame 120 for feeding packaging boxes, and a fixing rod 140 fixedly connected to the inner wall of the mounting frame 120 for supporting packaging boxes.

[0034] It should be noted that the mounting frame 120 is used to provide fixed support for the unloading plate 130 and the fixing rod 140. The fixing rod 140 is used to temporarily store the packaging boxes to be loaded. The packaging boxes can slide naturally down the unloading plate 130 along its sloping surface. The unloading plate 130 is used to receive the packaging boxes sliding down the fixing rod 140, ensuring that the packaging boxes are in a stable position before being pushed to the conveyor belt 110. The conveyor belt 110 is the final conveying channel after the packaging boxes are loaded, and is used to receive the packaging boxes pushed from the fixing rod 140.

[0035] The feeding mechanism 200 includes a pushing component 210 for pushing the packaging boxes on the top of the fixed rod 140 one by one toward the conveyor belt 110, a distributing component 220 for controlling the packaging boxes in the unloading plate 130 to move one by one to the top of the fixed rod 140, and a transmission component 230 that can use the rotational power of the pushing component 210 to drive the conveyor belt 110 to operate continuously.

[0036] The pushing component 210 is located inside the mounting frame 120, the material distribution component 220 is located outside the material discharge plate 130, and the transmission component 230 is located between the conveyor belt 110 and the pushing component 210.

[0037] The pushing assembly 210 includes a rotating rod 211 rotatably connected to the inner surfaces of both sides of the mounting frame 120, a swing rod 212 fixedly sleeved on the outer surface of the rotating rod 211, a hinge rod 213 hinged to the other end of the swing rod 212, a movable rod 214 hinged to the outer surface of the hinge rod 213, and a plurality of pusher blocks 215 integrally formed on the top of the movable rod 214 for pushing materials.

[0038] Specifically, the push assembly 210 also includes a support rod 216 that is fixedly mounted on the inner wall of the mounting frame 120 via bearings and is used in conjunction with the hinge rod 213, and a motor 217 that is adapted to be mounted on the outer side of the mounting frame 120 and is used in conjunction with the rotating rod 211.

[0039] Furthermore, the outer end face of the hinge rod 213 is hinged to the outer end face of the support rod 216;

[0040] Two sets of rotating rod 211, swing rod 212, hinge rod 213 and support rod 216 are provided to prevent the position of the pusher block 215 from shifting. When one set of rotating rod 211, swing rod 212, hinge rod 213 and support rod 216 is in operation, it can drive the other set of rotating rod 211, swing rod 212, hinge rod 213 and support rod 216 to move synchronously through the pusher block 215.

[0041] It should be explained that when the motor 217 drives the rotating rod 211 to rotate, it can drive the swing rod 212 to swing through the rotating rod 211. This causes the hinge rod 213 to perform a compound motion of swinging and translation under the pull of the swing rod 212. The hinge rod 213 then drives the movable rod 214 to form a periodic elliptical trajectory. Through the cooperation of the two sets of movable rods 214, the pusher block 215 is driven to move along the elliptical trajectory. Finally, the pusher block 215 accurately contacts the packaging box at the top of the fixed rod 140 and pushes it to move smoothly along the surface of the fixed rod 140 towards the conveyor belt 110.

[0042] Preferably, the material distribution assembly 220 includes a first helical gear 221 fixedly sleeved on the output end of the motor 217, a second helical gear 222 meshing with the outside of the first helical gear 221, a roller 223 fixedly connected to the inner surface of the second helical gear 222, a guide groove 224 formed on the outer surface of the roller 223, a force-bearing column 225 movably connected to the inner wall of the guide groove 224, and a slider 226 fixedly connected to the outer end face of the force-bearing column 225.

[0043] It should be noted that the material distribution assembly 220 also includes a baffle plate 227 fixedly connected to the outer surface of the slider 226 and used in conjunction with the material feeding plate 130, a positioning rod 228 fixedly connected to the outer surface of the mounting bracket 120 and used to support the slider 226, and a spring 229 sleeved on the outside of the positioning rod 228.

[0044] Furthermore, the guide groove 224 includes a force-applying groove 224-1 formed on the outer surface of the roller 223, and a force-relieving groove 224-2 formed on the other side of the roller 223.

[0045] Specifically, the outer end face of the roller 223 is fixedly mounted on the outer surface of the mounting frame 120 by bearings, the slider 226 is slidably sleeved on the outer surface of the positioning rod 228, the spring 229 is fixedly connected to the outer surface of the mounting frame 120, and its other end abuts against the slider 226. The two ends of the force application groove 224-1 and the force release groove 224-2 are interconnected.

[0046] It should also be noted that when the output end of motor 217 rotates, it drives the second helical gear 222 to rotate synchronously through the first helical gear 221, and then drives the roller 223 to rotate through the second helical gear 222. When the roller 223 rotates, it first contacts and squeezes the force-bearing column 225 through the force-applying groove 224-1, causing the force-bearing column 225 to drive the slider 226 and the baffle plate 227 to move synchronously downward along the positioning rod 228, opening the end of the feeding plate 130, so that the packaging at the bottom inside can be opened. As the box slides along the feed plate 130 to the top of the fixed rod 140, the roller 223 continues to rotate until the force release groove 224-2 contacts the force-bearing column 225. At this point, the squeezing force of the force application groove 224-1 on the force-bearing column 225 disappears. The reaction force of the spring 229 pushes the slider 226 and the baffle plate 227 to move upward synchronously, covering the end of the feed plate 130 again to prevent subsequent packaging boxes from continuing to slide down. This achieves the effect of controlling the packaging boxes in the feed plate 130 to slide one by one to the top of the fixed rod 140.

[0047] Preferably, the transmission assembly 230 includes a belt 231 that passes through the end of a rotating rod 211 on the side away from the motor 217 via a pulley, and a transmission column 232 that passes through the other end of the belt 231 via a pulley and is used to drive the conveyor belt 110.

[0048] It should also be noted that the through end of the transmission column 232 is fixedly connected to the drive shaft of the conveyor belt 110. When one of the rotating rods 211 rotates with the motor 217, it drives the other rotating rod 211 to rotate synchronously through other components in the pushing assembly 210. This causes the corresponding rotating rod 211 to drive the transmission column 232 to rotate through the belt 231, and then drives the conveyor belt 110 to run continuously, so that the conveyor belt 110 can transport the packaging box pushed down from the top of the fixed rod 140.

[0049] When using,

[0050] Place the packaging boxes to be loaded onto the surface of the unloading plate 130, so that the packaging boxes are ready to be loaded naturally along the inclined surface of the fixing rod 140.

[0051] Then, the motor 217 is started, which drives the corresponding rotating rod 211 to rotate. The rotating rod 211 then drives the swing rod 212 to swing, which in turn pulls the hinge rod 213 to perform a combination of swinging and translational motion. The hinge rod 213 then drives the movable rod 214 to form a periodic elliptical trajectory cyclical motion. Finally, through the cooperation of the two sets of rotating rods 211, swing rods 212, hinge rods 213, and support rods 216, the movable rod 214 drives the pusher block 215 to move synchronously. Finally, the pusher block 215 accurately contacts the packaging box on the top of the fixed rod 140 through the elliptical trajectory cyclical motion and pushes it along the surface of the fixed rod 140 toward the conveyor belt 110.

[0052] At the same time, the output end of the motor 217 drives the second helical gear 222 to rotate through the first helical gear 221. The second helical gear 222 drives the roller 223 to rotate synchronously. The roller 223 first squeezes the force column 225 through the force groove 224-1, causing the force column 225 to drive the slider 226 and the baffle plate 227 to move down along the positioning rod 228, opening the end of the feeding plate 130, so that a single packaging box slides to the top of the fixing rod 140. Then the force release groove 224-2 of the roller 223 rotates to the position of contacting the force column 225. At this time, the reaction force of the spring 229 pushes the baffle plate 227 to reset and block the feeding plate 130.

[0053] Meanwhile, the rotating rod 211 on the side away from the motor 217 drives the transmission column 232 to rotate synchronously via the belt 231, and then drives the conveyor belt 110 to run via the transmission column 232. Finally, the conveyor belt 110 receives the packaging box pushed by the pusher block 215 and transfers it to the subsequent process to complete the automatic feeding process.

[0054] In summary, by setting up the feeding mechanism 200, it can not only automatically drive the movable rod 214 to drive the pusher block 215 to form a periodic elliptical trajectory, so that the pusher block 215 pushes the packaging box on the fixed rod 140 to the surface of the conveyor belt 110, but also automatically control the baffle plate 227 at the end of the feed plate 130 to open and close at a fixed frequency, so as to ensure that the speed at which multiple packaging boxes slide to the fixed rod 140 remains consistent, thereby ensuring that the distance between adjacent packaging boxes on the surface of the conveyor belt 110 is equal, while avoiding the reduction of food processing quality due to the deviation of the packaging box distance.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
