Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, and specifically to a multi-functional double-layer conveyor. Background Art

[0002] When packing glutinous rice balls or dumplings, a plastic box tray is usually arranged in the packaging bag. Through the plastic box tray, each glutinous rice ball or dumpling has an independent space, preventing the glutinous rice balls or dumplings from sticking to each other during packaging, and also avoiding deformation due to extrusion during transportation and storage. In addition, through the square structure design of the plastic box tray, the regular square shape of the entire packaging bag is maintained. Conveyors, through automated and continuous conveying methods, greatly improve production efficiency and play an indispensable role in the food processing industry. In terms of the production and processing of glutinous rice balls or dumplings, after production and bagging, the bagged dumplings or glutinous rice balls need to be transported to the packing position by a conveyor for centralized packing of the bagged dumplings or glutinous rice balls.

[0003] After searching, the invention patent with the authorized announcement number CN108373048B discloses an automatic stacking and conveying system for asphalt shingles, including a shingle making machine. The shingle making machine has several discharge channels, and a conveyor is arranged below each discharge channel. The key point of its technical solution is that a stacking device for stacking asphalt shingles and releasing them at intervals on the conveyor for conveying is arranged on the conveyor, realizing the automatic stacking and transportation of asphalt shingles, thereby achieving the purpose of reducing labor costs.

[0004] Based on the above patent, combined with the existing solutions and the actual production and processing, the current conveyors for bagged glutinous rice balls or dumplings still have some problems, such as: 1. In the existing production and processing of glutinous rice balls or dumplings, the role played by the conveyor is relatively single, only used for conveying bagged dumplings or glutinous rice balls to the packing position. After conveying, manual stacking and packing of the bagged dumplings or glutinous rice balls are required, resulting in a single function of the existing conveyor and unable to achieve automatic stacking and packing processing. Manual stacking and packing operations are relatively cumbersome, increasing the work burden and affecting work efficiency at the same time. 2. In the above patent, the asphalt shingles will slide down through a ramp chute into the stacking device, and simple stacking is carried out through the sequential sliding of the asphalt shingles, but the function is still relatively single and unable to perform subsequent operations after stacking, such as unable to achieve automatic packing after stacking.

[0005] Therefore, we propose a multi-functional double-layer conveyor to facilitate the solution of the problems raised above. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the multifunctional double-layer conveyor, unlike the prior conveyor which only has the single function of conveying and transferring, realizes automatic neat stacking after conveying and automatic packing after stacking, thus ensuring the functional diversity and effectively improving the work efficiency; 1. After the linkage frame is driven to slide down, it drives the pressing block to move down synchronously, and the pressing block pushes the pulling plate to make the pulling plate flip on the pedestal frame. Through the sliding cooperation between the pulling plate and the spacing support plate, the pulling plate flips and drives the spacing support plate to move, so that the spacing support plate slides and shrinks on the pedestal frame, and the spacing support plate releases the temporary support for the bagged dumplings or glutinous rice balls. After the linkage frame is driven to slide down, it also drives the stacking bracket to move down synchronously, and the bagged dumplings or glutinous rice balls that lose their temporary support slide onto the stacking bracket for support and stacking. The pressing blocks are arranged at equal intervals on the linkage frame. In summary, the linkage frame intermittently slides down, driving the spacing support plate to intermittently shrink, so that multiple bagged dumplings or glutinous rice balls fall intermittently in sequence, and multiple bagged dumplings or glutinous rice balls are automatically and neatly stacked on the stacking bracket, which is different from the existing conveyor which only has the single function of transportation and transfer, ensuring functional diversity; Further, after the linkage frame drives the stacking bracket to move completely downward, the stacked bagged dumplings or glutinous rice balls are moved downward into the cavity of the blanking frame. Through the support of the blanking tray, the stacked bagged dumplings or glutinous rice balls are placed in the blanking frame. In addition, after the linkage frame drives the stacking bracket to move completely downward, by the sliding fit between the first pin and the loop groove, the stacking bracket is driven to contract and slide on the linkage frame to automatically release the support for stacking. The blanking frame is driven to drive the stacked bagged dumplings or glutinous rice balls to move downward and insert them into the outer packing box. After the blanking frame moves completely downward, through the limiting and pressing between the hook part and the unlocking groove, and through the meshing action between the rack part and the gear part, the linkage plate drives the blanking tray to turn and fold, automatically releasing the supporting function of the blanking tray. The stacked bagged dumplings or glutinous rice balls are automatically filled into the outer packing box, realizing the automatic packing process after stacking. Different from the existing manual stacking and packing operations, through the automatic setting, the work burden is effectively reduced and the work efficiency is improved; Further, the second-layer conveyor belt conveys the bagged dumplings or glutinous rice balls to the interval between the two guide plates. After the convex seat is driven to slide, it drives the pushing plate to slide synchronously. The pushing plate toggles the bagged dumplings or glutinous rice balls, and with the limiting assistance of the two guide plates, the bagged dumplings or glutinous rice balls are conveyed forward to the stacking mechanism, realizing automatic and precise docking during conveying, ensuring the operation convenience. In addition, through the sliding fit between the second pin and the driving groove, after the convex seat drives the pushing plate to slide back to its original position, the pushing plate contracts and slides into the convex seat. Through the reciprocating action, continuous and precise pushing supply of the bagged dumplings or glutinous rice balls during conveying can be realized, ensuring the automatic performance of the conveyor; 2. Clamping plate parts are arranged on both output ends of the bidirectional telescopic rod. The bidirectional telescopic rod can operate the two clamping plate parts to slide in opposite directions or relative directions. The bagged dumplings or glutinous rice balls are clamped and fixed by the two clamping plate parts. The bidirectional telescopic rod is driven by the servo motor to form a rotating structure on the bearing frame. After the bidirectional telescopic rod drives the clamping plate parts to rotate, the purpose of automatically adjusting the conveying orientation of the bagged dumplings or glutinous rice balls is achieved, ensuring subsequent precise docking and supply.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: The present invention provides a technical solution: a multi-functional double-layer conveyor, which addresses the problems of the existing conveyor having a single function, being unable to achieve automatic and neat stacking of bagged dumplings or glutinous rice balls, and being unable to achieve automatic boxing after stacking. The second-layer conveyor belt 4 is used for conveying bagged dumplings or glutinous rice balls, and the first-layer conveyor belt 1 is used for conveying outer packaging boxes. A stacking mechanism 5 is arranged between the first-layer conveyor belt 1 and the second-layer conveyor belt 4. The bagged dumplings or glutinous rice balls are conveyed to the stacking mechanism 5 through the second-layer conveyor belt 4 and are temporarily supported by the spaced pallets 10. When the stacking bracket 13 is driven to move down one unit, the spaced pallets 10 automatically release the support, causing the bagged dumplings or glutinous rice balls to fall onto the stacking bracket 13. Based on moving down one unit, the stacking bracket 13 continuously moves down intermittently, and after that, the stacking and supporting of the bagged dumplings or glutinous rice balls are completed, that is, the automatic stacking process is completed. When the stacking bracket 13 has completely moved down, the stacked bagged dumplings or glutinous rice balls are supported by the blanking pallet 16 and placed in the blanking frame 14. The stacking bracket 13 automatically releases the stacking support. The outer packaging box is conveyed to directly below the stacking mechanism 5 through the first-layer conveyor belt 1. The blanking frame 14 is driven to drive the stacked bagged dumplings or glutinous rice balls to move down and insert into the outer packaging box. After the blanking frame 14 has completely moved down, the blanking pallet 16 automatically releases the support, and the stacked bagged dumplings or glutinous rice balls are automatically filled into the outer packaging box, completing the automatic boxing process.

[0021] For this technical solution: Please refer to Figures 1 - 13 , a multi-functional double-layer conveyor, including a first-layer conveyor belt 1. The first-layer conveyor belt 1 is arranged horizontally and is used for conveying outer packaging boxes. Integrally structured legs are vertically arranged on the front and rear sides of the housing of the first-layer conveyor belt 1, and it is placed on the working site through one of the legs. On the front and rear sides of the first-layer conveyor belt 1, there are symmetrically arranged pushing frames 2 for adjusting the position of the outer packaging box, and the pushing frames 2 are driven by the first telescopic rods 3 fixed on the first-layer conveyor belt 1 to form a sliding structure on the first-layer conveyor belt 1; It also includes a two-layer conveyor belt 4 and a feeding mechanism 6. The housing of the two-layer conveyor belt 4 is clamped and fixedly connected to the leg of the one-layer conveyor belt 1 by bolts, placed directly above the one-layer conveyor belt 1, arranged in a parallel state with the one-layer conveyor belt 1, and the two-layer conveyor belt 4 is used for transporting bagged dumplings or glutinous rice balls. A stacking mechanism 5 is vertically downward on the right side of the two-layer conveyor belt 4. The stacking mechanism 5 corresponds to the pushing frame 2 and is placed directly above the pushing frame 2. Through the stacking mechanism 5, the bagged dumplings or glutinous rice balls are automatically and neatly stacked, and the automatic boxing operation after stacking is assisted. The feeding mechanism 6 is arranged directly to the left of the stacking mechanism 5 and is arranged in a parallel state directly above the two-layer conveyor belt 4. The feeding mechanism 6 is used for automatically pushing the bagged dumplings or glutinous rice balls into the stacking mechanism 5. A guide plate 7 for limiting the position during the transportation of the bagged dumplings or glutinous rice balls is arranged directly below the feeding mechanism 6.

[0022] Specifically, in this technical solution, the two-layer conveyor belt 4 is fixedly connected directly above the one-layer conveyor belt 1. The bagged dumplings or glutinous rice balls are transported into the stacking mechanism 5 through the two-layer conveyor belt 4. According to Figure 1 、 Figure 4 、 Figure 12 and Figure 13 shown, the guide plate 7 is symmetrically arranged before and after with respect to the horizontal central axis of the two-layer conveyor belt 4. After the guide plate 7 is installed, it is fixedly connected to the housing of the two-layer conveyor belt 4 by bolts. It is vertically attached to the belt surface of the two-layer conveyor belt 4 and is parallel to the two-layer conveyor belt 4. It corresponds to the left side of the stacking mechanism 5. Since the left end of the guide plate 7 is bent in an arc, the bent ends of the two guide plates 7 form an "eight" - shaped structure with the large opening facing left. Also, since the distance between the two guide plates 7 is adapted to the width of the bagged dumplings or glutinous rice balls, during the transportation of the bagged dumplings or glutinous rice balls by the two-layer conveyor belt 4, with the assistance of the bent ends in the guide plate 7, they enter the space between the two guide plates 7. Through the limitation of the two guide plates 7, the bagged dumplings or glutinous rice balls are kept in the forward transportation, that is, the bagged dumplings or glutinous rice balls can be accurately and positively docked with the stacking mechanism 5; After a bagged dumpling or glutinous rice ball enters the space between the two guide plates 7 through the transportation of the two-layer conveyor belt 4, stop the transportation work of the two-layer conveyor belt 4. After the current bagged dumpling or glutinous rice ball is toggled into the stacking mechanism 5 by the feeding mechanism 6 and wait for the feeding mechanism 6 to reset, then start the two-layer conveyor belt 4 again to transport the next bagged dumpling or glutinous rice ball, and so on, continuously transporting the bagged dumplings or glutinous rice balls into the stacking mechanism 5; Since an opening is provided in the middle of the left shell wall of the main frame shell 8 for allowing bagged dumplings or glutinous rice balls to enter and exit the shell cavity in the main frame shell 8, and since the guide plate 7 is used for limiting the position of bagged dumplings or glutinous rice balls during transportation, it is arranged directly below the feeding mechanism 6. The feeding mechanism 6 includes an outer shell frame 30, a convex seat 31 and a pushing plate 32. After being arranged, the outer shell frame 30 is arranged in parallel with the second-layer conveyor belt 4, and its left end is fixedly connected to the frame of the second-layer conveyor belt 4 by bolts, and its right end is docked at the opening of the main frame shell 8, and its right end is inserted into the shell cavity of the main frame shell 8, and its right end is fixedly connected to the shell wall of the main frame shell 8 by bolts, and then because the convex seat 31 After placement, the wide portion thereof is movably clamped in the right section frame cavity of the outer shell frame 30, and the narrow portion thereof is movably inserted through the lower side cavity opening of the right section frame cavity of the outer shell frame 30 and extends outward, so that the convex seat 31 is positioned on the outer shell frame 30 in an active state. After placement, the fourth telescopic rod 33 is fixedly installed on the left section frame body of the outer shell frame 30 by bolts, and the output end thereof is plugged in and fixedly connected to the wide portion of the convex seat 31 by bolts. The fourth telescopic rod 33 is started to extend and operate, and the convex seat 31 is driven to move by the fourth telescopic rod 33, so that the convex seat 31 slides rightward in the right section frame cavity of the outer shell frame 30, that is, the convex seat 31 slides toward the stacking mechanism 5; Since both the front and rear sides of the wide portion of the convex seat 31 are provided with through-going slide grooves, and since both the front and rear sides of the push plate 32 are provided with second pins 35, the push plate 32 is arranged in a square frame structure. After the push plate 32 is arranged, it is movably clamped in the convex seat 31, and its lower end movably penetrates through the narrow portion of the convex seat 31 to extend outward, and the front and rear second pins 35 movably penetrate through the front and rear slide grooves of the convex seat 31 to extend outward, so that the push plate 32 is positioned on the convex seat 31 in an active state, and the convex seat 31 is driven to slide and drives the push plate 32 to move synchronously; Since the feeding mechanism 6 is arranged on the left side of the stacking mechanism 5, it is used for automatically pushing the bagged dumplings or glutinous rice balls into the stacking mechanism 5. Since the pushing plate 32 is in a toggling state, it is vertically extended downward on the convex seat 31, and its lower end is pressed and fitted with the left side of the bagged dumplings or glutinous rice balls, after the convex seat 31 is driven to slide, the pushing plate 32 follows the convex seat 31 to slide to the right synchronously, and the lower end of the pushing plate 32 is connected to the bagged dumplings or glutinous rice balls in a toggling manner, and the bagged dumplings or glutinous rice balls are toggled by the pushing plate 32 to be transported to the positive limit position of the stacking mechanism 5 at the interval between the two guide plates 7; Since the left shell wall opening of the main frame shell 8 is provided with an integrated feed trough 801, the feed trough 801 is parallel to the second-layer conveyor belt 4, and the feed trough 801 is connected with the shell cavity in the main frame shell 8 through the left shell wall opening of the main frame shell 8, and since the longitudinal section of the feed trough 801 is a "U"-shaped structure, it is divided into a bottom trough wall and two side trough walls respectively located on the front and rear sides of the bottom trough wall, the bottom trough wall in the feed trough 801 is connected to the second-layer conveyor belt 4, wherein the bottom trough wall and the second-layer conveyor belt 4 are flush with each other, and the front and rear side groove walls in the feeding trough 801 are respectively connected to the front and rear guide plates 7, wherein the two side groove walls are respectively flush with the plate surfaces of the two guide plates 7. Since the width dimension of the feeding trough 801 is the same as the width dimension of the shell cavity in the main frame shell 8, after the bagged dumplings or glutinous rice balls are pushed by the pushing plate 32, they are conveyed in a limited forward direction through the two guide plates 7, pass through the feeding trough 801 and enter the shell cavity of the main frame shell 8, completing the conveyance of the bagged dumplings or glutinous rice balls to the stacking mechanism 5.

[0023] At the same time, in the above technical scheme, according to the above, driving grooves 36 are provided on the front and rear side walls of the right section of the outer shell frame 30, and the front and rear driving grooves 36 correspond to the front and rear second pins 35 respectively. The driving groove 36 includes a horizontal slide groove path 3601 and an inclined slide groove path 3602 connected to the left end of the horizontal slide groove path 3601. Since the second pin 35 is vertically threaded and fixed to the push plate 32 after being installed, the front and rear second pins 35 are movably inserted in the front and rear driving grooves 36 respectively, and the two constitute a sliding structure. When the push plate 32 follows the convex seat 31 to slide to the right to move the bagged dumplings or glutinous rice balls, the second pin 35 slides along the horizontal slide groove path 3601, and the horizontal slide groove path 3601 is set in parallel with the outer shell frame 30, so as to keep the push plate 32 in a vertical downward extending state on the convex seat 31, that is, to keep the push plate 32 in a toggling state; Because a fifth spring 34 is installed at the sliding connection between the push plate 32 and the convex seat 31, the fifth spring 34 is movably inserted in the frame cavity of the push plate 32, one end of which is pressed against the frame cavity wall of the push plate 32, and the other end of which is pressed against the convex seat 31. When the push plate 32 slides downward and extends out on the convex seat 31, the fifth spring 34 is elastically deformed by being squeezed. In addition, since the inclined slide groove path 3602 is arranged in an inclined upward state, and the spacing dimension between the upper end point of the inclined slide groove path 3602 and the horizontal slide groove path 3601 is equal to the maximum distance dimension of the push plate 32 when it is retracted and slid. When the push plate 32 follows the convex seat 31 to slide to the right to complete the transportation of the bagged dumplings or glutinous rice balls to the stacking mechanism 5, the fourth telescopic rod 33 is started to retract and move. The second pin 35 then slides along the horizontal slot 3601 into the inclined slot 3602, and slides along the inclined slot 3602. The sliding fit between the second pin 35 and the inclined slot 3602 and the elastic deformation and reset of the fifth spring 34 allow the push plate 32 to shrink and slide in the convex seat 31, and the second pin 35 and the push plate 32 move synchronously to form a sliding structure on the convex seat 31. The push plate 32 shrinks and slides upward and is stored in the convex seat 31, thereby releasing the toggling state of the push plate 32 and not affecting the next conveying of the second-layer conveyor belt 4.

[0024] Specifically, in the technical solution, a stacking mechanism 5 is vertically arranged downwardly on the right side of the second-layer conveyor belt 4, and the stacking mechanism 5 is used to automatically and neatly stack the bagged dumplings or glutinous rice balls. The stacking mechanism 5 includes a main frame shell 8, a sub-frame shell 9, a spacing support plate 10, a stacking support frame 13, a material unloading frame 14 and a material unloading support plate 16. The spacing support plate 10 is used to temporarily support the bagged dumplings or glutinous rice balls. Figure 3 , Figure 4 and Figure 5 As shown, auxiliary frame shells 9 are arranged on the shell walls on both sides of the front and rear sides of the main frame shell 8. After the auxiliary frame shell 9 is placed, it is fixedly connected to the shell wall of the main frame shell 8 by bolts. It is arranged on the shell wall of the main frame shell 8 in a cover state and is parallel to the main frame shell 8. Since the main frame shell 8 is arranged in a vertical state on the right side of the second-layer conveyor belt 4 after being placed, and since an integrated connecting frame is arranged on the shell wall of the auxiliary frame shell 9 to the left, after the stacking mechanism 5 is docked with the second-layer conveyor belt 4, the connecting frame in the auxiliary frame shell 9 is fixedly connected to the casing of the second-layer conveyor belt 4 by bolts, that is, the fixed placement of the main frame shell 8 and the auxiliary frame shell 9 on the second-layer conveyor belt 4 is completed; Since the specifications and dimensions of the shell cavity in the main frame shell 8 are compatible with the specifications and dimensions of the bagged dumplings or glutinous rice balls, even if the bagged dumplings or glutinous rice balls can be limited and dropped in the shell cavity in the main frame shell 8, and since the middle parts of the front and rear shell walls of the main frame shell 8 are provided with spacing pallets 10, the spacing pallets 10 are arranged parallel to the feeding trough 801 after being installed, and the bottom surface of the feeding trough 801 The groove wall is flush with the plate surface of the spacing pallet 10. After the bagged dumplings or glutinous rice balls are transported into the shell cavity of the main frame shell 8 through the feeding trough 801 by the switching of the supply mechanism 6 and the limiting of the guide plate 7, the front and rear sides of the bagged dumplings or glutinous rice balls are respectively overlapped on the front and rear two spacing pallets 10, and the bagged dumplings or glutinous rice balls are temporarily supported by the spacing pallet 10.

[0025] Specifically, in the technical solution, in the automatic release of the temporary support operation of the spacer support plate 10, according to Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, a wedge-shaped strip of an integrated structure is provided on the side of the pedestal frame 11 facing the linkage frame 19, wherein the wedge-shaped strip is symmetrically arranged on the pedestal frame 11, and a wedge-shaped strip of an integrated structure is provided on the shell cavity wall of the side of the sub-frame shell 9 facing the linkage frame 19, wherein the wedge-shaped strip is symmetrically arranged on the sub-frame shell 9. Since the linkage frame 19 is arranged in an "L"-shaped structure, it is divided into two parts, a transverse frame body and a longitudinal frame body. A wedge-shaped groove adapted to the wedge-shaped strip in the pedestal frame 11 is provided on the side of the longitudinal frame body of the linkage frame 19 facing the pedestal frame 11, and the longitudinal frame body of the linkage frame 19 faces the sub-frame shell. A wedge-shaped groove is provided on one side of 9 to match the wedge-shaped strip in the sub-frame shell 9, and the wedge-shaped grooves on both sides of the linkage frame 19 are symmetrically arranged on the longitudinal frame body of the linkage frame 19. Since the pedestal frame 11 is placed in the shell cavity of the sub-frame shell 9 after being installed, a gap is reserved between the two. After the linkage frame 19 is installed, it is movably clamped in the shell cavity of the sub-frame shell 9, wherein the longitudinal frame body is placed in the gap between the pedestal frame 11 and the sub-frame shell 9, and the wedge-shaped grooves on both sides are movably clamped together with the wedge-shaped strip in the pedestal frame 11 and the wedge-shaped strip in the sub-frame shell 9, respectively, so that the linkage frame 19 is positioned on the sub-frame shell 9 in an active state; Since a through-going slide groove is provided at the upper end of the shell cavity wall of one side of the sub-frame shell 9 facing the longitudinal frame body in the linkage frame 19, the upper end of the longitudinal frame body in the linkage frame 19 is fixedly connected with a connecting frame in a vertical state by bolts. After the linkage frame 19 is installed, the connecting frame of the longitudinal frame body can move through the slide groove of the sub-frame shell 9 and extend outward. Moreover, since the third telescopic rod 20 is fixedly installed on the outer shell wall of the sub-frame shell 9 by bolts after installation, and the output end thereof is plugged in and fixedly connected to the connecting frame in the linkage frame 19 by bolts, the third telescopic rod 20 is started to retract and the linkage frame 19 is driven to move by the third telescopic rod 20, so that the linkage frame 19 slides downward in the gap between the pedestal frame 11 and the sub-frame shell 9, even if the linkage frame 19 slides downward in the shell cavity of the sub-frame shell 9; Since the longitudinal frame of the linkage frame 19 is provided with pressure blocks 21 at equal intervals from top to bottom, the two constitute a synchronous motion structure, and the pressure blocks 21 are connected to the outward section of the pull plate 17 by pushing and pressing. Since the longitudinal section of the pull plate 17 is a "V"-shaped structure, a section of the pull plate 17 facing the spacing support plate 10 is the inward section, and a section of the pull plate 17 away from the spacing support plate 10 is the outward section. The corner in the middle of the pull plate 17 is interspersed with a shaft column and fixedly connected by bolts, and the left and right ends of the shaft column are fixedly clamped with bearings. After the guide plate 7 is placed, it is movably clamped in the seat cavity of the pedestal frame 11, and the two ends of the shaft column are respectively connected The bearings are inserted into the cavity walls on both sides of the pedestal frame 11, and the first torsion spring 18 is installed at the flip connection between the pull plate 17 and the pedestal frame 11. The first torsion spring 18 is symmetrically arranged about the vertical center axis of the pull plate 17. After the first torsion spring 18 is installed, it is movably sleeved on the central axis of the pull plate 17, one end of which is clamped on the pull plate 17, and the other end is clamped on the cavity wall of the pedestal frame 11. After the linkage frame 19 is driven, the pressing block 21 is driven to slide downward synchronously, and the pressing block 21 pushes the outward section of the pull plate 17, so that the pull plate 17 performs a flipping movement in the cavity of the pedestal frame 11, and the first torsion spring 18 is subjected to force and elastically deformed; Since the upper side wall of the pressing block 21 overlaps the groove cavity wall of the longitudinal frame body in the linkage frame 19 after the pressing block 21 is installed, when the pressing block 21 is subjected to force, the pressing block 21 can only be turned over by the downward thrust, and cannot be turned over by the upward thrust. In addition, since the lower side wall of the inner section of the pulling plate 17 overlaps the seat cavity wall of the pedestal frame 11 after the pulling plate 17 is installed, when the outer section of the pulling plate 17 is subjected to force, the pulling plate 17 can only be turned over by the downward thrust, and cannot be turned over by the upward thrust. Since the end of the spacing support plate 10 facing the main frame shell 8 is the inward end, and the end of the spacing support plate 10 facing the pedestal frame 11 is the outward end, a round rod parallel to the spacing support plate 10 is fixedly connected in the empty groove facing the outward end of the spacing support plate 10 by bolts, and since the inward section of the pull plate 17 is provided with a through-state slide groove, after the pull plate 17 is placed, the inward section of the pull plate 17 is movably clamped in the empty groove facing the outward end of the spacing support plate 10, and the round rod in the spacing support plate 10 The sliding groove of the inner section of the pull plate 17 is inserted movably, and because the inner section of the pull plate 17 and the spacing support plate 10 are arranged in an inclined state, the inner section of the pull plate 17 is connected with the outer end of the spacing support plate 10 by sliding through the round rod in the spacing support plate 10. After the pull plate 17 is driven to flip, the spacing support plate 10 is pulled to move through the sliding cooperation between the inner section of the pull plate 17 and the outer end of the spacing support plate 10; Since the pedestal frame 11 is vertically fixed and connected to the middle of the shell wall of the main frame housing 8 by bolts after being installed, both left and right sides of the outer end of the spacer plate 10 are provided with integrated structure limiting cylindrical parts. After the spacer plate 10 is installed, the outer end together with the limiting cylindrical parts is movably clamped in the cavity wall of the pedestal frame 11, and the inner end movably penetrates through the shell wall of the main frame housing 8 and is inserted into the cavity of the main frame housing 8, so that the spacer plate 10 is positioned on the pedestal frame 11 in a movable state. Also, since a first spring 12 is installed at the connection between the spacer plate 10 and the pedestal frame 11, the first spring 12 is symmetrically arranged about the vertical central axis of the spacer plate 10. After the first spring 12 is installed, it is movably inserted into the cavity wall of the pedestal frame 11. One end of it presses against the limiting cylindrical part in the spacer plate 10, and the other end presses against the cavity wall of the pedestal frame 11. After the spacer plate 10 is pulled, it contracts and slides in the cavity of the pedestal frame 11, causing the first spring 12 to be elastically deformed by extrusion. After the spacer plate 10 contracts and slides, it is received into the cavity of the pedestal frame 11, automatically releasing the temporary support for the bagged dumplings or glutinous rice balls. In addition, when the pressing block 21 loses the extrusion on the outer section plate body of the pull plate 17, by using the elastic deformation reset of the first torsion spring 18 and the elastic deformation reset of the first spring 12, the pull plate 17 is reset and flipped in the cavity of the pedestal frame 11, and the spacer plate 10 loses the pull and resets and extends and slides in the cavity of the pedestal frame 11. The spacer plate 10 extends back into the cavity of the main frame housing 8 again to temporarily support the next bagged dumpling or glutinous rice ball.

[0026] At the same time, in the above technical solution, according to the above, since the distance between two adjacent pressing blocks 21 is greater than the thickness of the bagged dumplings or glutinous rice balls, the pressing blocks 21 are equidistantly arranged from top to bottom on the longitudinal frame of the linkage frame 19. The distance between two adjacent pressing blocks 21 is the distance for the linkage frame 19 to move one unit. Driven by the third telescopic rod 20, the linkage frame 19 moves downward in an intermittent manner based on a unit distance. Through the intermittent control of the spacer plate 10 by multiple pressing blocks 21 for contraction movement, multiple bagged dumplings or glutinous rice balls fall intermittently in sequence in the cavity of the main frame housing 8.

[0027] Specifically, in this technical solution, the operation of supporting and stacking the bagged dumplings or glutinous rice balls is carried out through the stacking bracket 13. According to Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9As shown, the stacking bracket 13 is symmetrically arranged front and back with respect to the vertical central axis of the main frame housing 8. It is disposed directly below the spacer plate 10. Since the stacking bracket 13 is arranged in a "U" - shaped structure, including a transverse plate body and two longitudinal plate bodies located on the left and right sides of the transverse plate body, the section of the longitudinal plate body of the stacking bracket 13 facing the main frame housing 8 is in an "L" - shaped structure. After the stacking bracket 13 is installed, its transverse plate body is movably clamped in the cavity of the transverse frame body in the linkage frame 19, and the longitudinal plate body passes through the cavity of the transverse frame body in the linkage frame 19 and extends outwards, so that the stacking bracket 13 is positioned in a movable state on the linkage frame 19. The linkage frame 19 drives the stacking bracket 13 to form a synchronous lifting and sliding structure; Since through - slots are provided on the front and back cavity walls of the lower cavity of the main frame housing 8, and the through - slots are symmetrically arranged left and right on the main frame housing 8. After the stacking bracket 13 is installed, the "L" - shaped section of its longitudinal plate body passes through the through - slot in the main frame housing 8 and extends into the cavity of the main frame housing 8. After the linkage frame 19 moves down one unit, the stacking bracket 13 follows the linkage frame 19 and also moves down by one unit as a reference. The distance of one unit is greater than the thickness of the bagged dumplings or glutinous rice balls. After the spacer plate 10 loses the support for the bagged dumplings or glutinous rice balls, the "L" - shaped sections of the longitudinal plate bodies of the front and rear stacking brackets 13 respectively overlap on the front and back sides of the bagged dumplings or glutinous rice balls to support the bagged dumplings or glutinous rice balls; Since the specification size of the cavity in the blanking frame 14 is the same as that of the cavity in the main frame housing 8, that is, the cavity wall in the main frame housing 8 is flush with the cavity wall in the blanking frame 14. And since the blanking frame 14 is movably clamped in the lower cavity of the main frame housing 8 after installation, through - slots are provided on the front and back cavity walls of the blanking frame 14, and the through - slots are symmetrically arranged left and right on the blanking frame 14, so that the through - slots in the blanking frame 14 are correspondingly connected to the through - slots in the main frame housing 8. The linkage frame 19 drives the stacking bracket 13 to move down intermittently, so that the stacking bracket 13 slides down in the lower cavity of the main frame housing 8, and the "L" - shaped section of the longitudinal plate body of the stacking bracket 13 slides along the through - slots in the blanking frame 14 and the through - slots in the main frame housing 8. After the stacking bracket 13 moves down intermittently, the bagged dumplings or glutinous rice balls are successively supported and stacked on the "L" - shaped section of the longitudinal plate body of the stacking bracket 13, and the stacking bracket 13 drives the stacked bagged dumplings or glutinous rice balls into the cavity of the blanking frame 14.

[0028] Specifically, in this technical solution, the blanking support plate 16 is used to perform the blanking and supporting operation on the stacked bagged dumplings or glutinous rice balls. According to Figure 3 、 Figure 7 、 Figure 9 、 Figure 10 and Figure 11As shown, lower material supporting plates 16 are provided at the lower ends of the left and right side frame walls of the lower material frame 14. After being installed, the lower material supporting plates 16 are horizontally placed in the frame cavity of the lower material frame 14. Since the width dimension of the lower material supporting plate 16 is smaller than the spacing dimension between the two stacking brackets 13 in the extended state, after the stacking brackets 13 are completely moved down under the drive of the linkage frame 19, they cross over the lower material supporting plate 16 and are placed below the lower material supporting plate 16. After the stacked bagged dumplings or glutinous rice balls are driven by the stacking brackets 13 and fall into the frame cavity of the lower material frame 14, the left and right sides of the lowermost bagged dumpling or glutinous rice ball are respectively lapped on the two lower material supporting plates 16. The stacked bagged dumplings or glutinous rice balls are supported by the lower material supporting plates 16, and the stacked bagged dumplings or glutinous rice balls are placed in the frame cavity of the lower material frame 14.

[0029] Specifically, in this technical solution, when automatically releasing the stacking operation of the stacking brackets 13, according to Figure 3 , Figure 5 , Figure 9 and Figure 10 shown, return grooves 23 for driving the automatic contraction of the stacking brackets 13 are provided on the left and right cavity walls of the lower cavity of the auxiliary frame housing 9. The return groove 23 includes a first vertical groove path 2301, a horizontal groove path 2302, a second vertical groove path 2303 and an inclined groove path 2304. Since the first pin 26 is vertically and threadedly fixed to the stacking bracket 13 after being installed, and is symmetrically arranged left and right on the stacking bracket 13, the two first pins 26 respectively correspond to the two return grooves 23. The first pin 26 and the stacking bracket 13 form a synchronous movement structure. Also, since through grooves are provided on the left and right cavity walls of the transverse frame cavity of the linkage frame 19, the first pin 26 is movably inserted through the through groove of the transverse frame of the linkage frame 19 and extends outwards, and its extended end is movably inserted into the return groove 23. The first pin 26 forms a sliding structure in the return groove 23. When the stacking bracket 13 drives the stacked bagged dumplings or glutinous rice balls to move downwards, the first pin 26 moves downwards synchronously with the stacking bracket 13. At this time, the first pin 26 slides along the first vertical groove path 2301. The first vertical groove path 2301 is arranged in parallel with the lifting direction of the stacking bracket 13. That is, when the stacking bracket 13 moves downwards, the stacking bracket 13 remains in a sliding and extended state on the transverse frame of the linkage frame 19, and the stacking bracket 13 remains in the stacking and supporting state; Since the end of the first vertical groove path 2301 is in communication with the beginning of the horizontal groove path 2302, and the horizontal groove path 2302 is arranged perpendicular to the first vertical groove path 2301 and parallel to the contraction sliding direction of the stacking bracket 13. Also, since limiting blocks are fixedly clamped on both the left and right sides inside the groove cavity of the horizontal frame body in the linkage frame 19, a spring groove is formed on the longitudinal plate body of the stacking bracket 13. After the stacking bracket 13 is installed, the limiting blocks in the linkage frame 19 are movably clamped in the spring groove of the stacking bracket 13. A third spring 27 is installed at the sliding connection between the stacking bracket 13 and the linkage frame 19. The third spring 27 is symmetrically arranged about the vertical central axis of the stacking bracket 13. After the third spring 27 is installed, it is movably inserted into the spring groove of the stacking bracket 13, with one end pressing against the groove wall of the spring groove of the stacking bracket 13 and the other end pressing against the limiting block in the linkage frame 19. When the stacking bracket 13 drives the stacked bagged dumplings or glutinous rice balls to completely move downward, the first pin 26 slides along the first vertical groove path 2301 to the communication point between the first vertical groove path 2301 and the horizontal groove path 2302. Using the elastic deformation reset of the third spring 27, the stacking bracket 13 contracts and slides inside the horizontal frame body of the linkage frame 19, and the first pin 26 slides along the horizontal groove path 2302 to the communication point between the horizontal groove path 2302 and the second vertical groove path 2303. After the stacking bracket 13 contracts and slides, the "L" section plate body of the longitudinal plate body of the stacking bracket 13 is received into the chute of the main frame housing 8, losing the supporting effect on the bagged dumplings or glutinous rice balls stacked in the cavity of the blanking frame 14; Since the end of the horizontal groove path 2302 is in communication with the beginning of the second vertical groove path 2303, and the second vertical groove path 2303 is arranged parallel to the first vertical groove path 2301. Also, since the distance dimension between the second vertical groove path 2303 and the first vertical groove path 2301 is equal to the maximum distance dimension of the contraction sliding of the stacking bracket 13, the third telescopic rod 20 is started to extend and operate, so that the linkage frame 19 drives the stacking bracket 13 to rise and slide synchronously. When the stacking bracket 13 rises and slides back to its original position, the first pin 26 moves upward synchronously with the stacking bracket 13. At this time, the first pin 26 slides along the second vertical groove path 2303 to the communication point between the second vertical groove path 2303 and the inclined groove path 2304, keeping the stacking bracket 13 in a contracted state on the horizontal frame body of the linkage frame 19, not contacting the stacked bagged dumplings or glutinous rice balls, and not affecting the rising and sliding back of the stacking bracket 13 to its original position; Since the tail end of the second vertical groove path 2303 is connected to the head end of the inclined groove path 2304, and the inclined groove path 2304 is in an inclined state facing the first vertical groove path 2301, and since the tail end of the inclined groove path 2304 is connected to the head end of the first vertical groove path 2301, when the stacking bracket 13 rises and resets and slides, the first pin 26 slides along the second vertical groove path 2303 to the connection between the second vertical groove path 2303 and the inclined groove path 2304, and then slides along the inclined groove path 2304 to the connection between the inclined groove path 2304 and the first vertical groove path 2301. Through the sliding fit between the first pin 26 and the inclined groove path 2304, the stacking bracket 13 is driven to extend and reset and slide on the transverse frame of the linkage frame 19, that is, the "L" section plate of the longitudinal plate in the stacking bracket 13 is placed back into the housing cavity of the main frame housing 8. After the stacking bracket 13 extends and resets and slides, the third spring 27 is elastically deformed under force; Since a blocking block 24 for limiting the first pin 26 is provided at the connection between the first vertical groove path 2301 and the inclined groove path 2304, the blocking block 24 has a "T" - shaped structure, and the end facing the return groove 23 is provided with an inclined tongue - like structure. After the blocking block 24 is installed, it is movably clamped in the housing wall of the sub - frame housing 9, and its inclined tongue end is movably inserted into the connection between the first vertical groove path 2301 and the inclined groove path 2304, so that the blocking block 24 is positioned in the housing wall of the sub - frame housing 9 in a movable state. Also, since a second spring 25 is installed at the sliding connection between the blocking block 24 and the sub - frame housing 9, the second spring 25 is symmetrically arranged about the vertical central axis of the blocking block 24. One end of it abuts against the blocking block 24, and the other end abuts against the housing wall of the sub - frame housing 9. Moreover, since the inclined side wall of the inclined tongue end in the blocking block 24 faces the inclined groove path 2304, when the first pin 26 slides along the inclined groove path 2304 towards the first vertical groove path 2301, the first pin 26 pushes the blocking block 24 through the inclined side wall of the inclined tongue end in the blocking block 24, causing the blocking block 24 to contract and slide at the connection between the first vertical groove path 2301 and the inclined groove path 2304, and causing the second spring 25 to be elastically deformed under extrusion. When the first pin 26 slides into the first vertical groove path 2301, the pushing force on the blocking block 24 is lost. Using the elastic deformation of the second spring 25 to reset, the blocking block 24 extends and resets and slides at the connection between the first vertical groove path 2301 and the inclined groove path 2304 to block the first pin 26 and limit the first pin 26 in the first vertical groove path 2301.

[0030] Meanwhile, in the above technical solution, according to the above, since the end of the pressing block 21 is inserted and rotatably connected with a shaft column, after the pressing block 21 is installed, its end is movably clamped in the groove cavity of the longitudinal frame in the linkage frame 19, and both ends of the shaft column are respectively clamped and fixedly connected to the two side groove cavity walls of the longitudinal frame in the linkage frame 19 by bolts. Also, since a second torsion spring 22 is installed at the flipping connection of the pressing block 21 and the linkage frame 19, the second torsion spring 22 is symmetrically arranged left and right with respect to the vertical central axis of the pressing block 21. After the second torsion spring 22 is installed, it is movably sleeved on the shaft column of the pressing block 21, one end of it is clamped on the pressing block 21, and the other end of it is clamped on the groove cavity wall of the longitudinal frame in the linkage frame 19. Moreover, since the pressing block 21 is in an inclined downward state on the longitudinal frame of the linkage frame 19, and the pressing block 21 and the outer plate body of the pulling plate 17 are arranged in an inclined state with respect to each other. When the linkage frame 19 rises and resets and slides, the pressing block 21 undergoes a flipping motion under the downward thrust of the pulling plate 17, and the pulling plate 17 cannot undergo a flipping motion under the upward thrust, that is, during the rising and reset movement of the linkage frame 19, it is not affected by the blocking of the pulling plate 17. After being pushed, the pressing block 21 flips and closes on the longitudinal frame of the linkage frame 19, and the second torsion spring 22 is elastically deformed under the force. In addition, after the pushing force on the pressing block 21 is removed, the pressing block 21 is reset and flipped and unfolded on the longitudinal frame of the linkage frame 19 by using the elastic deformation of the second torsion spring 22.

[0031] Specifically, in this technical solution, the automatic boxing operation after stacking is assisted by the stacking mechanism 5, and the blanking frame 14 drives the stacked bagged dumplings or glutinous rice balls to move downward for filling operation into the outer packaging box. According to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 11As shown in the figure, the second telescopic rod 15 is composed of a telescopic rod body and a connecting rod frame. The middle part of the upper end of the connecting rod frame is sleeved and fixedly connected to the output end of the telescopic rod body by bolts. Since through unlocking grooves 802 are provided on the left and right cavity walls of the lower shell cavity of the linkage plate 28, connecting frames are fixedly connected to the left and right sides of the upper end of the blanking frame 14 by bolts. After the blanking frame 14 is placed, it is movably clamped in the lower shell cavity of the main frame shell 8, and its lower end movably penetrates through the cavity opening of the lower shell cavity of the main frame shell 8 and extends outwards. And the connecting frame movably penetrates through the unlocking groove 802 and is placed outside the main frame shell 8. Also, since the telescopic rod body of the second telescopic rod 15 is inserted into the upper shell cavity of the main frame shell 8 after being placed, and the telescopic rod body is fixedly installed on the upper shell cavity wall of the main frame shell 8 by bolts. And the lower end of the connecting rod frame is inserted and fixedly connected to the connecting frame of the blanking frame 14 by bolts. The stacked bagged dumplings or glutinous rice balls are placed in the frame cavity of the blanking frame 14 by two blanking trays 16. Start the contraction operation of the telescopic rod body in the second telescopic rod 15, so that the connecting rod frame in the second telescopic rod 15 drives the blanking frame 14 to move downward, and the blanking frame 14 drives the stacked bagged dumplings or glutinous rice balls to slide downward in the lower shell cavity of the main frame shell 8; Since pushing frames 2 for adjusting the position of the outer packaging box are symmetrically arranged on the front and rear sides of the first-layer conveyor belt 1, the pushing frame 2 has an "L" - shaped structure and is divided into a horizontal frame body parallel to the first-layer conveyor belt 1 and a vertical frame body perpendicular to the horizontal frame body. After the pushing frame 2 is placed, it is vertically attached to the belt surface of the first-layer conveyor belt 1. Also, since the first telescopic rods 3 are symmetrically arranged about the horizontal central axis of the first-layer conveyor belt 1, the two first telescopic rods 3 are respectively used to independently drive the movement of the two pushing frames 2. After the first telescopic rods 3 are placed, they are fixedly installed on the casing of the first-layer conveyor belt 1 by bolts. The output end movably penetrates through the casing of the first-layer conveyor belt 1, and the output end is inserted and fixedly connected to the horizontal frame body of the pushing frame 2 by bolts. The first-layer conveyor belt 1 drives the outer packaging box to be conveyed directly below the stacking mechanism 5. After the outer packaging box is conveyed and moved, it is attached to the vertical frame body in the pushing frame 2. Due to the blocking of the vertical frame body in the pushing frame 2, the left half of the box cavity of the outer packaging box is correspondingly directly below the stacking mechanism 5. The first-layer conveyor belt 1 stops conveying. Drive the two first telescopic rods 3 to expand and contract. Through the mutual cooperation of the two first telescopic rods 3, after the two pushing frames 2 slide on the first-layer conveyor belt 1, the horizontal frame bodies in the two pushing frames 2 clamp and fix the outer packaging box, and the last position of the left half of the box cavity in the outer packaging box is correspondingly directly below the stacking mechanism 5. Thus, the docking of the outer packaging box and the stacking mechanism 5 is completed; According to the above, when the stacking mechanism 5 places the bagged dumplings or glutinous rice balls into the outer packing box, first, the feeding frame 14 drives the stacked bagged dumplings or glutinous rice balls to move downward and then inserts them into the outer packing box, placing the stacked bagged dumplings or glutinous rice balls at the last position in the left half of the inner cavity of the outer packing box. Then, start the extension operation of the first telescopic rod 3 at the front and the contraction operation of the first telescopic rod 3 at the back, so that the pushing frame 2 at the front slides backward, and the pushing frame 2 at the back slides backward synchronously with the pushing frame 2 at the front, operating the position adjustment of the outer packing box to make the middle position of the left half of the inner cavity of the outer packing box correspond directly below the stacking mechanism 5. Again, place the next batch of stacked bagged dumplings or glutinous rice balls into the middle position of the left half of the inner cavity of the outer packing box through the feeding frame 14, and so on. Again, adjust the position of the outer packing box through the two pushing frames 2 to make the frontmost position of the left half of the inner cavity of the outer packing box correspond directly below the stacking mechanism 5, and complete the placement of the next batch of stacked bagged dumplings or glutinous rice balls. Thus, the placement of all the bagged dumplings or glutinous rice balls in the left half of the inner cavity of the outer packing box is completed; Also according to the above, after the front and rear first telescopic rods 3 contract and operate, the front and rear pushing frames 2 slide in opposite directions, releasing the clamping and fixing of the outer packing box by the transverse frame bodies in the two pushing frames 2 and removing the obstruction of the longitudinal frame bodies in the two pushing frames 2. The first conveyor belt 1 drives the outer packing box to convey and move again, making the right half of the inner cavity of the outer packing box correspond directly below the stacking mechanism 5. The first conveyor belt 1 stops conveying. At this time, the outer packing box passes over the longitudinal frame body in the pushing frame 2. The front and rear first telescopic rods 3 extend and operate, and the front and rear pushing frames 2 slide in opposite directions. Again, clamp and fix the outer packing box through the longitudinal frame bodies in the two pushing frames 2 and perform the position adjustment of the outer packing box to complete the placement of all the bagged dumplings or glutinous rice balls in the right half of the inner cavity of the outer packing box. After all the bagged dumplings or glutinous rice balls are packed into the outer packing box, it is transported outward through the first conveyor belt 1; Since the front and rear sides of the lower end of the linkage plate 28 are provided with integrally structured limit cylindrical parts, after the linkage plate 28 is installed, it is movably clamped in the groove cavity of the middle frame wall of the feeding frame 14, and the two limit cylindrical parts on both sides are respectively movably clamped on the two side walls of the groove cavity of the middle frame wall of the feeding frame 14, making the linkage plate 28 be positioned in an active state on the feeding frame 14. When the feeding frame 14 drives the stacked bagged dumplings or glutinous rice balls to descend and slide in the lower cavity of the main frame housing 8, it drives the linkage plate 28 to move downward synchronously; Since through unlocking grooves 802 are formed in the cavity walls on the left and right sides of the main frame housing 8, the two unlocking grooves 802 respectively correspond to the two linkage plates 28. Also, since the upper end of the linkage plate 28 is provided with an integrally formed hanging portion 2802 that extends outward, after the linkage plate 28 is installed, the hanging portion 2802 is movably inserted into the unlocking groove 802. Further, since a fourth spring 29 is installed at the sliding connection between the linkage plate 28 and the blanking frame 14, the fourth spring 29 is symmetrically arranged before and after with respect to the vertical central axis of the first torsion spring 18. After the fourth spring 29 is installed, it is movably inserted into the cavity of the middle frame wall of the blanking frame 14. One end of it abuts against the limiting cylindrical portion of the linkage plate 28, and the other end abuts against the middle frame wall of the blanking frame 14. When the linkage plate 28 is driven to move downward, the hanging portion 2802 slides downward in the unlocking groove 802. When the linkage plate 28 is driven to move completely downward, the hanging portion 2802 is connected to the lower side wall of the unlocking groove 802 by pressing, so that the reverse movement of the linkage plate 28 is blocked, and it slides upward in the frame wall of the blanking frame 14, causing the fourth spring 29 to be elastically deformed by extrusion; Since an open empty groove is formed at the lower end of the linkage plate 28, through grooves are formed in the cavity walls on the front and rear sides of the empty groove. The end of the blanking support plate 16 is inserted and fixedly connected with a shaft column through bolts. Bearings are fixedly clamped at both the front and rear ends of the shaft column, and the end of the shaft column is movably clamped in the empty groove of the linkage plate 28. The two ends of the shaft column respectively pass through the through grooves on both sides of the linkage plate 28, and the two ends of the shaft column respectively connect the bearings and are inserted into the empty groove walls on both sides of the middle frame wall of the blanking frame 14. Also, since gear portions 1601 with an integrally formed structure are provided on both the front and rear sides of the end of the blanking support plate 16, the center of the gear portion 1601 coincides with the flipping center of the blanking support plate 16. After the blanking support plate 16 is installed, the two gear portions 1601 are respectively movably inserted into the two through grooves of the linkage plate 28. Further, rack portions 2801 are formed on both the front and rear through grooves of the linkage plate 28. The orientation of the rack portion 2801 in the left linkage plate 28 is opposite to the orientation of the rack portion 2801 in the right linkage plate 28, and the rack portion 2801 is meshed and connected with the gear portion 1601. After the linkage plate 28 is driven to slide upward in the frame wall of the blanking frame 14, through the meshing action between the rack portion 2801 and the gear portion 1601, the blanking support plate 16 is driven to flip and fold on the frame wall of the blanking frame 14, and the left and right blanking support plates 16 are flipped and folded in opposite directions; When the blanking support plate 16 is flipped and folded and stored in the empty groove of the middle frame cavity of the blanking frame 14, the plate surface of the blanking support plate 16 is flush with the frame cavity wall of the blanking frame 14. After the blanking support plate 16 is flipped and folded, it loses the support for the stacked bagged dumplings or glutinous rice balls, so that the stacked bagged dumplings or glutinous rice balls fall into the outer packing box through the blanking frame 14, completing the automatic boxing process.

[0032] Embodiment 2: Based on Embodiment 1 of the present invention, please refer to Figures 14 - 15 the technical solution shown. After the tangyuan or dumplings are bagged by the packaging equipment, they fall onto the conveyor belt of the conveyor and are conveyed to the stacking and packing position of the next process. After the bagged tangyuan or dumplings fall onto the conveyor belt, due to various factors, the orientations at which they fall onto the conveyor belt are different. When docking with the stacking and packing equipment in the next process, it is impossible to accurately dock. In response to the problem that the existing conveyor has a single function and cannot meet the use purpose of automatically adjusting the conveying orientation, which affects the accurate docking, the two clamping members 40 are operated by the bidirectional telescopic rod 38 to clamp the bagged dumplings or tangyuan, and the bidirectional telescopic rod 38 is driven to rotate by the servo motor 39 to perform the positive adjustment of the position of the bagged dumplings or tangyuan.

[0033] Specifically, in this technical solution, when performing the positive adjustment operation of the position of the bagged dumplings or tangyuan, according to Figure 14 and Figure 15 shown, the carrier 37 is arranged directly to the left of the guide plate 7. After being arranged, it is in a horizontal state and is fixedly connected to the frame of the second-layer conveyor belt 4 by bolts. Since the left end of the carrier 37 is fixedly installed with an image collector 41 (the image collector 41 is a prior art, and the docking method between the image collector 41 and the central processor is also a prior art, and the description in the specification will not be detailed), the image collector 41 is placed directly above the second-layer conveyor belt 4. When the second-layer conveyor belt 4 conveys the bagged dumplings or tangyuan, the image of the bagged dumplings or tangyuan is collected by the image collector 41, and after being input into the central processor, the position characteristics of the bagged dumplings or tangyuan are identified, the coordinate deviation between the target position and the standard position is calculated, and the central processor respectively starts the bidirectional telescopic rod 38 and the servo motor 39 to operate; Since clamping members 40 are arranged on both output ends of the bidirectional telescopic rod 38, the clamping members 40 are arranged to be sleeved and fixedly connected to the output ends of the bidirectional telescopic rod 38 by bolts and are in a vertically downward state. The bidirectional telescopic rod 38 is started to contract and operate, so that the sliding directions of the two clamping members 40 are arranged in the opposite direction, and the two clamping members 40 are used for clamping the bagged dumplings or tangyuan; Since the upper side of the bidirectional telescopic rod 38 is fixedly installed on the connecting frame through bolts, and an integrated shaft column is vertically upward arranged in the middle of the connecting frame, and a bearing is fixedly clamped on the shaft column. After the bidirectional telescopic rod 38 is arranged, it is placed under the bearing frame 37. The shaft column of the connecting frame together with the bearing is inserted into the middle of the bearing frame 37. Also, since the servo motor 39 is placed on the upper side of the bearing frame 37, after being arranged, it is fixedly installed in the middle of the bearing frame 37 through bolts, and its output end is inserted and fixedly connected to the shaft column of the connecting frame in the linkage plate 28 through bolts. Start the servo motor 39 to operate. Drive the bidirectional telescopic rod 38 through the servo motor 39, so that the bidirectional telescopic rod 38 rotates in the middle of the bearing frame 37, and the clamping plate member 40 clamps the bagged dumplings or glutinous rice balls to make a positive adjustment of the position, ensuring that the second-layer conveyor belt 4 can accurately convey the bagged dumplings or glutinous rice balls forward to the interval between the two guide plates 7.
