Description

Technical Field

[0001] The invention belongs to the technical field of biscuit packaging and conveying, and in particular relates to automatic feeding equipment for biscuit collective packaging. Background Art

[0002] In the biscuit processing, due to the presence of multiple complex processes, a large number of equipment are used, among which a large number of transport devices are used for transportation between equipment. At the same time, biscuit processing is a complex process involving multiple aspects such as raw material selection, production process, and product quality control. Flour is the main ingredient of biscuits. Appropriate selection of flour of different types and qualities can produce biscuits with different tastes. Sugar and fat are the key ingredients that give biscuits sweetness and crispness, and their selection also directly affects the quality of the biscuits. According to the existing public document CN114275226B, when bulk biscuits are finally packaged, they need to be collectively transported, and corresponding biscuit collective packaging and feeding equipment will be used.

[0003] Therefore, currently, when bulk biscuits are collectively packaged, they are conveyed flat on a conveyor belt. During packaging, the biscuits need to be converted from a flat state to a vertical stacked state for conveying. For collective stacking of biscuits, most of them are stacked in a staged manner. However, this method is only suitable for biscuits with consistent length and width. Biscuits with inconsistent length and width need to be turned after stacking, so manual intervention is required, which affects packaging efficiency. Since biscuits are fragile foods, bulk biscuits are prone to collision during stacking, resulting in uneven stacking and damage to the biscuits, affecting subsequent packaging. During the conveying process of biscuits, due to contact or collision between the biscuits and the structure, debris will remain on the surface of the structure. Under long-term conveying work, the newly conveyed biscuits may adhere to the old debris, causing the biscuits to be damaged or leave marks on the surface. At the same time, the debris adheres to the surface of the biscuits, affecting the neatness of the biscuits. To this end, we provide an automatic feeding device for biscuit collective packaging to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic feeding device for biscuit collective packaging. By using a steering frame, multiple stacked biscuits can be diverted to facilitate subsequent packaging of the biscuits. At the same time, the bipolar plate mechanism can attract debris with negative ions to prevent the debris from adhering to the biscuits and improve the comprehensiveness of debris recovery. The buffer rod can also be used to slow down and move the biscuits to reduce the collision of the biscuits and avoid damage to the biscuits.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention provides an automatic feeding device for collectively packaging biscuits, comprising a collective conveying assembly, comprising a conveying platform, a correction port is opened at the corner between the inclined surface of the conveying platform and the stable surface below, a buffer rod is provided at the position of the correction port, and the surfaces of the conveying platform on both sides of the correction port are sleeved with conveyor belts, a positioning slide assembly, comprising a plurality of groups of track-composed directional tracks covering the conveying surface of the conveying platform, a left end of each directional track is fixed with a centralized convergence track located on the stable surface of the conveying platform and used for sorting biscuits, an electrostatic separation assembly, comprising a combination frame located at the left position of the centralized convergence track and a bipolar plate mechanism located at the inner side of each conveyor belt and located inside the conveying platform, a lower end surface of the combination frame is fixed with a plurality of groups of corona discharge needles evenly distributed front and back, an arranging and steering assembly, comprising an arranging frame located at the right end position of the conveying platform and a plurality of steering frames located on the arranging frame and corresponding to the position of each directional track port, and a rotary cylinder for controlling the rotation of the steering frame is fixed to the lower end surface of the steering frame.

[0006] The present invention is further configured such that two guide rollers for driving the conveyor belt are rotatably arranged between the two side walls inside the conveyor platform, and a motor connected to the guide rollers through a chain is fixed to the outer side wall of the conveyor platform.

[0007] The present invention is further configured such that the front and rear walls of the bipolar plate mechanism are connected to the side walls of the conveyor platform by bolts, and a vibration rod is provided on the inner side of the conveyor belt located below the bipolar plate mechanism, both ends of which are rotatably connected to the two side walls of the conveyor platform. A plurality of vibration bars evenly distributed along the axial direction are fixed to the outer wall of the vibration rod, and the vibration rod is connected to the motor through a chain.

[0008] The present invention is further configured such that the bipolar plate mechanism is bolted to the side wall of the conveyor platform via ear plates fixed at the front and rear sides, and the buffer rod is transmission-connected to the rotating shaft end of the motor via a chain.

[0009] The present invention is further configured such that a plurality of toggle bars evenly distributed along the circumferential side are fixed to the outer wall of the buffer rod, and the circumferential side of the toggle bars is in contact with the surface of the conveyor belt, and the front and rear walls of the plurality of centralized convergence tracks are fitted together. Through the coordinated use of the centralized convergence track and the directional track, the width of the directional track is smaller than the width of the centralized convergence track. Therefore, the biscuits can be uniformly transported to the directional track through the inner bevel of the centralized convergence track. At the same time, only one biscuit can pass through the junction of the directional track and the centralized convergence track at a time, so that the biscuits can be stably assembled and stacked one by one.

[0010] The present invention is further configured such that assembly openings are opened at positions on the inner side walls of the conveying platform above the conveying surface corresponding to the two ends of the combination frame, and assembly blocks are fixed on the front and rear end faces of the conveying platform and inserted into the internal positions of the assembly openings, and the assembly blocks are locked in the assembly openings by bolts.

[0011] The present invention is further configured such that the front and rear parts of the lower end surface of the arranging frame are fixed with mounting bars bolted to the side walls of the conveying platform, a transverse bar is fixed at the position between the lower ends of the two mounting bars, vertical plates that are the same in number as the turning frames and are evenly distributed are fixed on the side walls of the transverse bars, multiple vertical plates and multiple turning frames are staggered up and down, pushing cylinders are fixed to the sides of the vertical plates, moving bars are fixed to the piston ends of the pushing cylinders passing through the vertical plates, and pushing plates are fixed to the upper end surfaces of the moving bars.

[0012] The present invention is further configured such that a plurality of baffles are fixed on the side of the horizontal bar opposite to the vertical plate, respectively used to block the port position of each steering frame, and each baffle is respectively consistent with the left and right directions of the port of each directional track, and a rotary cylinder is fixed on the lower end face of the steering frame for rotating the position of the steering frame, and the rotary cylinder is fixed on the side wall of the baffle, and a pushing port is opened through the side wall of each steering frame. When the steering frame is rotated downward 90°, the position of the pushing port will be consistent with the position of the moving bar. Therefore, when the pushing cylinder controls the moving bar to work, the moving bar will slide directly along the inner side wall of the pushing port, and drive the pushing plate to slide in the steering frame, thereby pushing out the biscuits in the steering frame.

[0013] The present invention is further configured such that a linkage plate is provided directly above the initial position of the steering frame, and a curved portion with an upward-tilted end is fixed to both ends of the linkage plate, and a step plate is fixed to the side wall of the arranging frame opposite to the linkage plate, and an adjustment port is provided on the side wall of the arranging frame above the step plate at the position corresponding to each linkage plate. After the use of the curved portion, when the steering frame is rotated upward and reset, the steering frame will not be restricted by the end position of the curved portion, so that the steering frame can stably push the curved portion to drive the linkage plate to move upward.

[0014] The present invention is further configured such that an adjusting block that slides in the internal position of the adjusting port is fixed on the side of the linkage plate, and a movable plate located above the step plate is fixed on the end face of the adjusting block away from the linkage plate. A penetrating positioning hole is provided in the middle position of the movable plate, and a positioning rod that passes through the internal position of the positioning hole is fixed between the step plate and the protrusion at the upper end of the arrangement frame. A return spring that is sleeved on the positioning rod and abuts against the protrusion at the upper end of the arrangement frame is fixed on the upper end face of the movable plate. Through the use of the return spring, the linkage plate can follow the steering frame to work synchronously at the first time, and at the same time, when the movable plate moves up and down, it will slide along the positioning rod through the positioning hole. Through the coordinated use of the step plate and the positioning rod, the movement stability of the linkage plate is improved.

[0015] The present invention has the following beneficial effects: When the steering frame is not in operation, one port of the steering frame will be aligned with the exit end of the directional track, while the other port will be blocked by the baffle. Therefore, the biscuits in the directional track will be directly moved to the steering frame after being transported out. Through the pushing of subsequent biscuits, multiple biscuits will enter the steering frame one after another. When the biscuits are in contact with the baffle, the sensor on the baffle will sense it and transmit a data signal. The external control center will control the rotary cylinder to work, and the rotary cylinder will drive the steering frame to rotate, thereby controlling the biscuits from vertical stacking to horizontal stacking, thereby reducing the probability of manual intervention and avoiding affecting the packaging efficiency.

[0016] After the biscuits are transported to the inclined surface of the conveyor belt, they slide down on the inclined part of the conveyor platform, and the end of the biscuit will be directly located between the two toggle bars. Therefore, when each biscuit is connected to the buffer rod, the toggle bar will slightly push the biscuit, so that the biscuit moves smoothly to the smooth surface of the directional track. At the same time, the buffer bar reduces the sliding collision strength of the biscuit, avoids contact between biscuits, and ensures that the biscuits will not be damaged due to collision.

[0017] When the biscuits are moved to the conveyor table under the operation of the front conveying equipment, the biscuits will first pass through the lower position of the combination rack, and the combination rack will cause the biscuits to carry negative ions, and the debris generated therein will also carry negative ions. Therefore, when the debris moves to the regional position of the bipolar plate mechanism, the strong electric field formed by the positive plate and the negative plate included in the bipolar plate mechanism will drive the negatively charged debris to move and migrate toward the positive plate, so that the debris is adsorbed on the surface position of the conveyor belt, and through the movement of the conveyor belt, the debris is driven to follow the movement. When the conveyor belt drives the debris to the lower position of the conveyor table, the distance between the debris and the bipolar plate mechanism will be enlarged, thereby reducing the close fit between the debris and the conveyor belt, and the debris can fall off from the surface position of the conveyor belt. By controlling the fit between the debris and the conveyor belt, the probability of the debris adhering to the biscuits is reduced, thereby effectively avoiding damage to the biscuit surface or leaving scars, and at the same time improving the comprehensiveness of debris recovery.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention. Example 1

[0034] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , which is the first embodiment of the present invention, provides an automatic feeding device for biscuit collective packaging. By using a steering frame 403, multiple stacked biscuits are diverted to facilitate subsequent packaging of the biscuits. At the same time, the bipolar plate mechanism 302 attracts the debris with negative ions to prevent the debris from adhering to the biscuits and improve the comprehensiveness of the debris recovery. The buffer rod 103 is used to slow down and move the biscuits to reduce the collision of the biscuits and avoid damage to the biscuits.

[0035] Specifically, the collection and conveying assembly 100 includes a conveying platform 101, a positioning slide assembly 200, including multiple sets of directional rails 201 covering the conveying surface of the conveying platform 101, an electrostatic separation assembly 300, including a combination frame 301 located to the left of the centralized convergence rail 202 and a bipolar plate mechanism 302 located on the inner side of each conveyor belt 102, and an arrangement and steering assembly 400, including an arrangement frame 401 located at the right end of the conveying platform 101 and multiple steering frames 403 located on the arrangement frame 401 and corresponding to the port position of each directional rail 201; By setting and using the above structure, through the stepped setting of the directional track 201, when the biscuits are flattened on the conveyor platform 101 for conveyance, the biscuits will slide down from the inclined surface of the conveyor platform 101, so that the biscuits stand upright and are stacked on the conveyor platform 101 for further conveyance, and the vertically stacked biscuits will be moved to the turning frame 403 one after another. When the biscuits inside the turning frame 403 are full, the turning frame 403 rotates 90 degrees, so that the biscuits are changed from a vertically standing state to a horizontally standing state, thereby realizing the direction adjustment, which is convenient for the subsequent packaging of the biscuits. At the same time, when the biscuits are moved to the conveyor platform 101 under the operation of the front conveying equipment, the biscuits will first pass through the lower position of the combination rack 301, and the combination rack 301 will be rotated 90 degrees. The rack 301 causes the biscuits to carry negative ions, and the debris generated therein also carries negative ions. Therefore, when the debris moves to the regional position of the bipolar plate mechanism 302, the strong electric field formed by the positive plate and the negative plate included in the bipolar plate mechanism 302 drives the negatively charged debris to move and migrate toward the positive plate, so that the debris is adsorbed on the surface position of the conveyor belt 102, and the movement of the conveyor belt 102 drives the debris to follow the movement. When the conveyor belt 102 drives the debris to the lower position of the conveyor platform 101, the distance between the debris and the bipolar plate mechanism 302 will be increased, thereby reducing the close fit between the debris and the conveyor belt 102, and the debris can fall off from the surface position of the conveyor belt 102.

[0036] according to Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 and Figure 12 A correction port 101a is provided at the corner between the inclined surface of the conveying platform 101 and the stable surface below. A buffer rod 103 rotatably connected to the front and rear walls of the conveying platform 101 is provided at the position of the correction port 101a. Conveyor belts 102 are sleeved on the surface of the conveying platform 101 on both sides of the correction port 101a. A centralized convergence track 202 located on the stable surface of the conveying platform 101 and used to sort the biscuits is fixed at the left end of each directional track 201. A plurality of groups of corona discharge needles 301b are fixed on the lower end surface of the assembly frame 301 and are evenly distributed front and back. A rotary cylinder 403b for controlling the rotation of the steering frame 403 is fixed on the lower end surface of the steering frame 403. When using the above-mentioned structure, after the biscuits are transported to the inclined surface position of the conveyor belt 102 by the conveyor belt 102, the biscuits will slide directly from the inclined position to the surface position of the buffer rod 103. At the same time, the buffer rod 103 adopts a soft structure, thereby reducing the impact force between the biscuits and the buffer rod 103. At the same time, the buffer will transfer the biscuits to the plane conveying position of the conveyor platform 101, and discharge through the corona discharge needle 301b to charge the biscuit crumbs. After the attraction treatment of the bipolar plate mechanism 302, the crumbs are tightly attached to the conveyor belt 102, ensuring that the crumbs will not adhere to the biscuits and realizing the comprehensive recovery of the crumbs. At the same time, the operation of the rotary cylinder 403b is controlled. The rotary cylinder 403b will drive the synchronous rotation of the steering frame 403, so that the steering frame 403 will turn the biscuits inside it to a horizontal position, so as to facilitate the subsequent packaging of multiple biscuits.

[0037] Further, according to Figure 3 and Figure 5 It can be seen that two guide rollers are rotatably arranged between the two side walls inside the conveyor platform 101, which are used to drive the conveyor belt 102 respectively. The outer wall of the conveyor platform 101 is fixed with a motor 104 connected to the guide roller through a chain. The front and rear walls of the bipolar plate mechanism 302 are connected to the side walls of the conveyor platform 101 by bolts. The inner side of the conveyor belt 102 below the bipolar plate mechanism 302 is provided with a vibration rod 303 that is rotatably connected to the two side walls of the conveyor platform 101 at both ends. The outer wall of the vibration rod 303 is fixed with a plurality of vibration bars 303a evenly distributed along the axial direction. The vibration rod 303 is connected to the motor through a chain. 104 transmission connection, when the motor 104 is working, it will synchronously drive the two guide rollers and the vibration rod 303 to rotate synchronously, so that the guide roller will drive the conveyor belt 102 connected to it to rotate, thereby controlling the movement of the biscuits on the conveyor platform 101 to ensure the stable flow of the biscuits. At the same time, the rotation of the vibration rod 303 will drive the vibration bar 303a to continuously push and shake the conveyor belt 102. Therefore, when the debris remaining on the surface of the conveyor belt 102 moves to the position closest to the vibration rod 303, the shaking force applied to the debris is the largest at this time, so that the debris will fall off the conveyor belt 102 at this point.

[0038] Further, according to Figure 3 、 Figure 5 、 Figure 11 and Figure 12It can be seen that the bipolar plate mechanism 302 is bolted to the side wall of the conveyor platform 101 through ear plates fixed on the front and rear sides, and the buffer rod 103 is connected to the rotating shaft end of the motor 104 through a chain. The outer wall of the buffer rod 103 is fixed with multiple toggle bars 103a evenly distributed along the circumference, and the circumference of the toggle bars 103a is in contact with the surface of the conveyor belt 102. The front and rear walls of multiple concentrated convergence rails 202 fit together. When the biscuits slide down on the inclined part of the conveyor platform 101, the end position of the biscuits will be directly between the two toggle bars 103a. Therefore, when each biscuit is connected with the buffer rod 103, the toggle bar 103a will slightly push the biscuit, so that the biscuit can be moved smoothly to the smooth surface of the directional rail 201.

[0039] It should be noted that when recycling biscuit crumbs, the corresponding recycling box needs to be installed in the internal position of the conveyor platform 101 so that the recycling box is consistent with the upper and lower positions of the conveyor belt 102. At the same time, a copper mesh connected to the ground is installed in the recycling box to release the residual charge in the crumbs. The electrostatic generator used is directly installed inside the external control box and connected to the electrode plate in the bipolar plate mechanism through an insulated cable. The motor 104 and various cylinders are controlled and processed through the external control box. The end corners of the electrode plates used in the bipolar plate mechanism 302 are all chamfered to prevent tip discharge. At the same time, the conveying surface of the conveyor platform 101 includes an upper stable surface, an inclined surface and a lower stable surface. Example 2

[0040] See also Figure 6 and Figure 10 On the basis of embodiment 1, in this embodiment, the assembly block 301a is installed in the assembly opening 101b by means of bolts, thereby ensuring the stable installation of the assembly frame 301.

[0041] Specifically, the inner side wall of the conveying platform 101 above the conveying surface is provided with assembly openings 101b at positions corresponding to the two ends of the assembly frame 301. The front and rear end surfaces of the conveying platform 101 are fixed with assembly blocks 301a inserted into the inner positions of the assembly openings 101b. The assembly blocks 301a are locked in the assembly openings 101b by bolts. By setting and using the above structure, the assembly block 301a is inserted into the assembly opening 101b, and the assembly block 301a and the conveying platform 101 are threadedly connected by bolts, so that the assembly block 301a is limited by the assembly opening 101b, so that the combination frame 301 can only move upward on the conveying platform 101, ensuring that the combination frame 301 is stably installed on the conveying platform 101. At the same time, after unscrewing the bolts, the combination frame 301 is moved upward, and the assembly block 301a can be quickly taken out of the assembly opening 101b. Example 3

[0042] See also Figure 1 、 Figure 4 、 Figure 7 and Figure 8 On the basis of Example 1, this embodiment can accurately push the biscuits in the turning frame 403 into the packaging equipment through the cooperation of the baffle 405b, the rotary cylinder 403b and the pushing cylinder 404.

[0043] Specifically, the front and rear parts of the lower end surface of the arrangement frame 401 are fixed with mounting bars 401a connected to the side walls of the conveyor platform 101 with bolts, and a horizontal bar 405 is fixed at the position between the lower ends of the two mounting bars 401a. The side walls of the horizontal bar 405 are fixed with vertical plates 405a that are the same in number and evenly distributed as the steering frames 403. The multiple vertical plates 405a and the multiple steering frames 403 are staggered up and down. The sides of the vertical plates 405a are fixed with push cylinders 404, and the piston ends of the push cylinders 404 that pass through the vertical plates 405a are fixed with moving bars 404. b. The upper end surface of the movable bar 404b is fixed with a pushing plate 404a. The side of the horizontal bar 405 opposite to the vertical plate 405a is fixed with a plurality of baffles 405b for blocking the port position of each steering frame 403, and each baffle 405b is respectively consistent with the left and right direction of the port of each directional track 201. The lower end surface of the steering frame 403 is fixed with a rotary cylinder 403b for rotating the position of the steering frame 403, and the rotary cylinder 403b is fixed on the side wall of the baffle 405b. The side wall of each steering frame 403 is penetrated by a pushing port 403a. By setting and using the above structure, when the steering frame 403 is in an inoperative state, one port position of the steering frame 403 will be aligned with the exit end of the directional track 201, and the other port position will be blocked by the baffle 405b. Therefore, the biscuits in the directional track 201 will be directly moved to the steering frame 403 after being conveyed out. Through the pushing of subsequent biscuits, multiple biscuits will enter the steering frame 403 one after another. When the biscuits are in contact with the baffle 405b, the sensor on the baffle 405b will sense it and transmit a data signal. The external control center will control the rotary cylinder 403b to work, thereby the rotary cylinder 403b will drive the rotary cylinder 403b to rotate. The steering frame 403 rotates and rotates the port of the steering frame 403 to the same height as the pushing plate 404a. At this time, the pushing cylinder 404 is controlled to work, and the pushing cylinder 404 will push the moving bar 404b to pass through the position of the pushing port 403a, thereby driving the pushing plate 404a to push the biscuits inside the steering frame 403 into the packaging equipment. When the biscuits are all pushed out of the steering frame 403, the pushing cylinder 404 is reset, and then the rotary cylinder 403b is reset, so that the port of the steering frame 403 is realigned with the position of the directional track 201, and then the biscuits will continue to enter the steering frame 403 and repeat the above work. Example 4

[0044] See also Figure 4 、 Figure 7 、 Figure 8 and Figure 9 On the basis of Example 1, this embodiment uses the linkage plate 402 in conjunction with the steering frame 403. When the steering frame 403 turns, the linkage plate 402 will move downward to block the port of the directional track 201 to prevent the biscuits from falling.

[0045] Specifically, a linkage plate 402 is provided just above the initial position of the steering frame 403, and a bent portion 402a with an upwardly tilted end is fixed to each end of the linkage plate 402. A step plate 401d is fixed to the side wall of the arrangement frame 401 opposite to the linkage plate 402, and an adjustment port 401b is provided on the side wall of the arrangement frame 401 above the step plate 401d at the position corresponding to each linkage plate 402. An adjustment block 401b is fixed to the side of the linkage plate 402 to slide inside the adjustment port 401b. 2b, a movable plate 402c is fixed to the end surface of the adjustment block 402b away from the linkage plate 402, and is located above the stepped plate 401d. A positioning hole 402c1 is formed in the middle of the movable plate 402c. A positioning rod 401c is fixed between the stepped plate 401d and the protrusion at the upper end of the arrangement frame 401, passing through the inner position of the positioning hole 402c1. A return spring 402d is fixed to the upper end surface of the movable plate 402c, which is sleeved on the positioning rod 401c and abuts against the protrusion at the upper end of the arrangement frame 401. By setting and using the above structure, when the steering frame 403 is rotating, the free fall of the linkage plate 402 and the pushing of the return spring 402d enable the linkage plate 402 to quickly block the directional track 201 to prevent the biscuits from falling. At the same time, after the steering frame 403 is reset, the steering frame 403 will push the curved portion 402a, causing the curved portion 402a to drive the linkage plate 402 to move upward, so that the linkage plate 402 will control the adjustment block 402b to slide along the adjustment port 401b and thereby drive the movable plate 402c to move upward, thereby compressing the return spring 402d, and the positioning rod 401c is in the positioning hole 402c1, so the positioning rod 401c will limit the return spring 402d to ensure that the return spring 402d is compressed stably, and at the same time, the initial position of the steering frame 403 is in a non-rotated state.
