Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of non-standard packaging equipment, and specifically discloses a food continuous wrapping equipment controlled through stroke linkage. BACKGROUND

[0002] Small block-shaped foods are generally individually packaged, and large batches are generally not bulk-packed but are packed in boxes. Therefore, the packaging equipment for this demand is various, and the types and specifications of small block-shaped foods are also diverse. Therefore, this equipment belongs to non-standard equipment, and designers need to design the mechanism according to the specific needs of users to meet the needs of actual production. In particular, in the application scenario of the present application, small block-shaped foods generally refer to small-box packaged small-dose chicken essence blocks. This food generally has a relatively smooth small-piece packaging box, and is convenient to store and take out. The applicant found that the known equipment for packaging and wrapping the same food has some optimization points in coordinating the continuity of the actions of stacking the food and packing the paper box into a box.

[0003] For example, the food stacking and feeding structure has a material transfer structure. The transfer structure may be biased in maintaining the neatness of the stack and the rapid transfer of the stacked stack. Either the stack is neat but the transfer efficiency is low, or the transfer efficiency is high but the stack may need additional arrangement structure to adjust the uneven state of the stack before entering the box. The rationality of the mechanical structure is lacking. For example, between the folding and boxing structure of the paper box and the structure of the food into the box, multiple linking mechanical structures may need to be set to ensure the smoothness of the action execution, and so on. Therefore, the applicant designs a new continuous wrapping equipment for small block-shaped foods to improve the production efficiency of the applicant. SUMMARY

[0042] The embodiments of the present application will be described below in conjunction with the accompanying drawings and related embodiments. The embodiments of the present application are not limited to the following examples, and the present application relates to the necessary components in the related technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the person skilled in the art.

[0043] In combination with Figures 1 to 3As shown, a food continuous wrapping device controlled by stroke linkage includes a rack 1 provided with feeding conveying belt 2 and discharging conveying belt 3 which are parallel to each other, the feeding conveying belt 2 and the discharging conveying belt 3 are separately arranged on both sides of the rack 1, the rack 1 is further connected with an operation table 4, and the material pushing part, the material grabbing part, the material transferring part and the material boxing part are sequentially arranged between the feeding conveying belt 2 and the discharging conveying belt 3 in the order of material transmission, wherein the material boxing part is composed of paper box board material rack 27, electric push plate, lifting boxing position, stable pressing rod 5 and crank sucker arm connected between the paper box board material rack and the electric push plate, the feeding conveying belt 2 transmits the unwrapped food to the material pushing part, the material boxing part pushes the wrapped food in the box to the discharging conveying belt, and the discharging conveying belt 3 discharges.

[0044] Based on the above main technical features, the implementation process of the present application can be understood in the following order according to the feeding and discharging direction: feeding (until the accumulated material reaches the upper limit of the pushing material) → pushing material → layering → transferring → top material → moving material → pressing material → paper box boxing → discharging, wherein when the top material is performed, the actions of taking paper box board → pushing paper box board → pressing material → paper box boxing are also performed at the same time. In combination with the above technical features, the specific implementation process of the present application is that the scattered food material of the boxing small block is fed along the feeding conveying belt 2 to the material pushing part, and after the number of one layer of material in the boxing requirement is accumulated, the material pushing part pushes the material to the material grabbing part at one time and repeats the above process until the number of one layer of material in the boxing requirement is satisfied, the material grabbing part grabs all the material of one layer to the material transferring part for layering and stacking and repeats the above process until the total number of the boxing is satisfied, the material of one box and the layering and stacking is transferred to the material boxing part, the crank sucker arm synchronously takes out the paper box board stacked in the flat state from the paper box board material rack 27 to the electric push plate during the layering and stacking of the foregoing material, the electric push plate pushes the paper box board to the lifting boxing position to wait for the material boxing and boxing packaging, at this time, the material transferring part pushes the stacked material to the top of the paper box board in place, the paper box board is folded and adhered in the lifting boxing position with the descending of the stable pressing rod 5 and the lifting boxing position, and finally the material is wrapped and boxed, and then the boxed small block food box is pushed to the discharging conveying belt 3 by the electric push plate, and then discharged by the discharging conveying belt 3 for subsequent boxing.

[0045] In the above process, the space between any two adjacent execution instruments is compact, so the transfer of materials between the execution instruments does not require too much time, which also reduces the demand for execution instrument travel arrangement. Basically, each driven mechanical execution instrument needs to travel a distance that is not too long, which helps to improve the efficiency of mechanical equipment operation, especially in the field of boxing and wrapping small block-shaped food targeted by the present application. The compact execution structure also reduces the probability of errors and reduces the work intensity of manual supervision. Each time the material is boxed, it can be completed in a relatively consistent operation, so for those skilled in the art, such a device that does not require too much complexity and almost no extra action is suitable for long-term production tasks without consuming too much production and maintenance cost.

[0046] Further, in the present application, the power source driving the mechanical structure that can perform any action is not mentioned in the present application. Based on the linear motion or circular motion it performs, it can be understood as being driven by an electrically driven cylinder, a linear motor or a rotary motor. In order to achieve the accuracy of the machine's execution, in addition to the sensors mentioned in the present application, the remaining execution components can optionally be equipped with sensors to assist the machine in performing more accurate actions. The type of sensor is generally infrared sensor. The technical purpose it achieves is to sense the presence and further determine whether the quantity meets the requirements, whether the material is in place, and other basic packaging process requirement information, and convert it into the trigger condition for the corresponding mechanical structure to execute. Finally, the electric control system and the necessary electrical structure required by the electric control system are used to complete the operation of each mechanical execution structure. The above unexplained technical features can be selectively assembled and implemented by those skilled in the art based on their existing technical conditions and similar or identical purposes.

[0047] In combination Figures 1 to 6 As shown in the further technical solution of the present application, the material grabbing part is composed of a vertical rack 6 standing above the rack 1, a translation slide rail connected to one side of the vertical rack 6, and a grabbing suction cup arm 7 erected on the translation slide rail and capable of performing horizontal reciprocating motion along the translation slide rail. The bottom of the grabbing suction cup arm 7 is provided with a plurality of suction cups for grabbing food. In combination with the drawings, the entire material grabbing part is installed and arranged in close proximity to the feeding conveyor belt 2, the material pushing part and the material transferring part. The translation slide rail is wrapped and protected by a necessary shell above the vertical rack 6, which is opposite to the C-shaped stacking mold 10 below for stacking materials and the stacking opening 17. The grabbing suction cup arm 7 moves along the translation slide rail through the track moving mechanism. If necessary, the grabbing suction cup arm 7 and the track moving mechanism are connected through an electric lifting structure. In this way, it is ensured that the suction cup will not be blocked by the C-shaped stacking mold 10 during the transfer of the material after sucking enough amount of material.

[0048] Combination Figures 1 to 6 As shown in the figure, as one of the preferred embodiments of the present application, the material pushing part includes a pushing plate 8 arranged on one side of the feeding conveyor 2, a stop plate 9 fixed on the upper surface of the feeding conveyor 2, and a C-shaped stacking mold 10 fixed at the far end of the advancing direction of the pushing plate 8, the stop plate 9 is provided with a column calculation infrared sensor, and the C-shaped stacking mold 10 is provided with a row calculation infrared sensor, which is installed on the feeding conveyor 2 of the previous station and the material grabbing part of the next station, and the stop plate 9 with a blocking surface perpendicular to the advancing direction of the feeding conveyor 2 is arranged on the pushing plate 8 driven by a linear motor, so that the material will be sequentially blocked on the blocking surface of the stop plate 9 to form a column of materials after reaching the stop plate 9, until the column of materials approximately meets the required number of materials for a column of boxes, under the sensing of the column infrared sensor, the pushing plate 8 pushes the column of materials away from the feeding conveyor 2, and the C-shaped stacking mold 10 corrects it to a neat column, then the pushing plate 8 retreats to push the next column of materials, under the sensing of the row calculation infrared sensor, the C-shaped stacking mold 10 arranges the required number of rows of materials to meet the requirement of a layer of boxes, and triggers the adjacent grabbing suction cup arm 7 to suck a whole layer of materials to transfer to the loading platform 16.

[0049] Combination Figures 1 to 6As shown, as one of the preferred embodiments of the present application, the material transfer part includes a placing panel 11 erected between the feeding conveyor 2 and the discharging conveyor 3, a rotating placing rack 12 arranged below the placing panel 11, and a moving stack frame 13 arranged above the placing panel 11, the rotating placing rack 12 is connected in the middle to the output end of a horizontal rotating mechanism 14 fixed in the rack, symmetrically fixed at both ends with a stacking lifting mechanism 15, and a load carrying platform 16 arranged at the output end of the stacking lifting mechanism 15, the placing panel 11 is respectively provided with a stacking opening 17 and a feeding opening 18 corresponding to the stacking lifting mechanism 15, the moving stack frame 13 matches the feeding opening 18, the food is sent from the stacking opening 17 to the load carrying platform 16 below layer by layer until the number of boxes is reached, the rotating placing rack 12 is driven by the horizontal rotating mechanism 14 to switch to below the feeding opening 18, and then sent out from the feeding opening 18 upward, and the completed stacking food is pushed as a whole to the lifting box loading position through the moving stack frame 13. In the above structure, the moving stack frame 13 is a metal frame body which can accommodate at least one box of material and is permeable up and down, driven by a linear motor mechanism, and pushes the material lifted out of the feeding opening 18 on the placing panel 11 to the subsequent box loading lifting platform 20 arranged closely, and in the stacking opening 17 and the feeding opening 18, a side wall is arranged around for protection, to avoid the deviation of the material during the lifting of the load carrying platform 16, the axis of the horizontal rotating mechanism 14 can be hingedly fixed to the placing panel 11, to improve its stability, and under horizontal rotation, the stacked material can be continuously transferred to the subsequent box loading position, wherein the stacking lifting mechanism 15 lowers by one layer after carrying one layer of material when the load carrying platform 16 is below the stacking opening 17, to ensure that the suction cup arm 7 only needs to move to the same position each time to correctly place the material, and after a box of material is neatly stacked on the load carrying platform 16, the rotating platform is translated to below the feeding opening 18, the stacking lifting mechanism 15 lifts the load carrying platform 16 to send it into the moving stack frame 13, and then pushed to the box loading lifting platform 20 by the moving stack frame 13, and the structure is very compact.

[0050] In combination Figures 1 to 10As shown, as one of the preferred embodiments of the present application, the lifting box loading position comprises a support 19 fixed in the frame 1 and a box loading lifting platform 20 arranged in the support 19. The support 19 is composed of two vertical plates arranged oppositely, and a pair of clamping plates 21 arranged oppositely between the two vertical plates. The top end of the vertical plate is fixed with an L-shaped limiting plate 22 arranged horizontally for limiting the folded edge of the paper box plate in the flat state, so as to avoid the deviation of the wrapping position caused by excessive feeding. The clamping plate 21 is fixed on a clamping plate shaft 24 arranged between the two vertical plates and driven by a motor crank 23 fixed on one side of the vertical plate to swing around the shaft. As the intersection of the box loading work step, the L-shaped limiting plate 22 of the support 19 allows the paper box plate in the flat state to accurately enter the folding position, and then the folded edge ear is bent between the two clamping plates 21 with the continuous descent of the box loading lifting platform 20. The paper box is formed and fixed in the mutual extrusion of the clamping plate 21 and the material. The hot melt adhesive for edge bonding is sprayed at the adjacent inductive hot melt adhesive nozzle 25. Therefore, the action is continuous and rapid. The motor crank 23 can efficiently and accurately perform the action, so that the clamping plate shaft 24 can accurately and appropriately bend the folded edge ear of the paper box plate, avoiding crushing the wrapped material.

[0051] In combination Figures 1 to 3 , Figures 7 to 9 As shown, as a further embodiment of the above, the support 19 and the electric push plate are provided with an inductive hot melt adhesive nozzle 25 fixed above the support. The inductive hot melt adhesive nozzle 25 is symmetrically arranged on both sides of the support 19. The inductive hot melt adhesive nozzle 25 is connected with a hot melt adhesive feeding mechanism 26 installed on the side of the frame 1 and connected with the glue outlet of the hot melt adhesive feeding mechanism 26. The hot melt adhesive feeding mechanism 26 is a conventional hot melt adhesive feeding unit. The inductive hot melt adhesive nozzle 25 senses whether the folded edge ear of the paper box plate at the glue spraying position passes through the nozzle, and sprays hot melt adhesive at four positions respectively. The inductive hot melt adhesive nozzle 25 is essentially composed of an infrared sensor and a hot melt adhesive nozzle, and is controlled by the operation table 4.

[0052] In combination Figures 1 to 3 , Figure 11 As shown, as one of the preferred embodiments of the present application, the paper box plate material rack 27 is an open metal frame body, which is fixed on the surface of a vertical fixed plate 29 installed and fixed above the frame 1, and is inclined to correspond to the stroke trajectory of the crank suction cup arm. An open port 28 is formed below the paper box plate material rack 27 for the paper box plate in the flat state to leave the paper box plate material rack 27. The paper box plate material rack 27 has a simple structure, and utilizes the flexibility of the paper box plate itself. One paper box plate is taken by the crank suction cup arm through the open port 28 arranged below each time, and the subsequent paper box plate material pile is clamped in the paper box plate material rack 27 by gravity and is taken out one by one with the inclined arrangement.

[0053] In combinationFigures 1 to 3 , Figure 11 As a further embodiment of the above, the crank arm is composed of a crank rocker mechanism 30 installed on the surface of the vertical fixed plate 29 and a paper box plate suction cup 31 fixed on the rocker of the crank rocker mechanism 30, as shown in the figure. The paper box plate suction cup 31 corresponds to the paper box plate material rack 27 at the starting position of the stroke and to the electric push plate at the end position of the stroke under the drive of the crank rocker mechanism 30. The crank rocker mechanism 30 is shown in the figure, and the action is executed quickly and reasonably, and the structure is simple and reliable. It is a mature planar four-bar mechanism, and the paper box plate suction cup 31 is convenient for taking paper box plates.

[0054] In combination Figures 1 to 10 As a further embodiment of the above, the electric push plate includes a paper box plate placing plate 32 fixed above the rack 1, two guide baffles 33 parallel to the top of the paper box plate placing plate 32, a push plate motor 34 fixed below the horizontally placed paper box plate placing plate 32, and a paper box plate push plate 35 fixed on the output end of the push plate motor 34. The paper box plate placing plate 32 is provided with an avoidance groove 36 for the paper box plate push plate 35 to move towards the lifting and boxing position. The starting position of the stroke of the paper box plate push plate 35 corresponds to the end position of the stroke of the paper box plate suction cup 31. The structure at this position is shown in the figure. Essentially, after the paper box plate is detected to be placed on the paper box plate placing plate 32, the paper box plate push plate 35 is driven by the push plate motor 34 to complete the action of pushing the paper box plate to the boxing lifting platform 20 / pushing the completed material box to the outfeed conveyor 3. The guide baffles 33 can ensure that the posture of the paper box plate is correct and does not fall out. The avoidance groove 36 is set to avoid the continuous falling of the paper box plate. The paper box plate push plate 35 only needs to be set to a sufficient height to be able to touch the objects placed on the paper box plate placing plate 32. It can meet the two actions described above, which is very convenient and compact. Alternatively, a separate outfeed pushing mechanism 42 can be configured for the feeding conveyor 3, which is independent of the push plate motor 34 and does not interfere with each other. The design requirements for the structural space can be further reduced.

[0055] In combination Figures 1 to 3 , Figure 9 With Figure 10As shown, as one of the preferred embodiments of the present application, the lower part of the boxing lifting platform 20 is connected to a vertical rack 38 through a fixed rod 37, the rack 38 is engaged with the output end of a rack motor 39 fixed in the rack 1, one side of the rack 38 is fixedly connected with a vertical lifting rod 40, the stable pressing rod 5 is fixedly connected above the lifting rod 40, the lower part of the stable pressing rod 5 is connected with a stable pressing plate 41 which is suitable in size and faces the boxing lifting platform 20, the stable pressing plate 41 is coaxial with the fixed rod 37 in the vertical direction, this structure also belongs to compact layout, the stable pressing plate 41 ensures that the materials will not be scattered when boxing, and the coaxial fixed rod 37 can ensure that the materials are uniformly and balanced stressed, through the mutual connection of the rack 38 and the lifting rod 40, the stable pressing plate 41 and the boxing lifting platform 20 can be synchronized, which is also the compact and stable layout structure design guarantee.

[0056] In summary, compared with other similar non-standard equipment, the present application is more suitable for the actual production needs of the applicant, because the overall layout of the present application can be more compactly arranged, so that the layout will show a more reasonable state, and the mechanical structure itself also benefits from the advantages of compact structure. When performing the action required for the work step, no extra action is performed, so that the scattered food in the form of a square can be quickly and accurately sent out of the equipment after the mechanical equipment performs the action of stacking, boxing and packaging, for further boxing. Overall, the present application performs the action of folding the paper box board into a box to wrap and stack the food, and the equipment action is clean, neat and accurate, so the work efficiency is higher, which can effectively reduce the work intensity of the operator operating the equipment and improve the efficiency of enterprise production.

[0057] Therefore, in view of the above technical features, the technical features of the present application are mainly focused on the reasonable matching between the linkage and the mechanical execution part, which is combined with the simplified electric control structure to make the quick boxing of small food blocks into a more efficient and easy-to-control mechanical execution process. The whole process requires a lower setting of the electric control unit and a lower construction of the electric control system. The small food blocks are directly sent to the packaging paper at the boxing position to realize the steps of paper box forming and material entering the box in one step. For those skilled in the art, it is a relatively simple but efficient and reasonable optimization among many non-standard mechanical solutions that achieve the technical purpose.

[0058] The above is only a preferred embodiment of the present application, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
