Description

Technical Field

[0001] The present invention relates to the technical field related to conveyors, and in particular to a multifunctional double-layer conveyor. Background Art

[0002] When packaging glutinous rice balls or dumplings, a plastic tray is usually placed in the packaging bag. The plastic tray provides each glutinous rice ball or dumpling with an independent space, preventing the glutinous rice balls or dumplings from sticking to each other in the package and also preventing the glutinous rice balls or dumplings from being deformed due to squeezing during transportation and storage. In addition, the square structure design of the plastic tray maintains the regular square shape of the entire packaging bag.

[0003] Conveyors greatly improve production efficiency through automated and continuous conveying methods, and play an indispensable role in the food processing industry. As far as the production and processing of glutinous rice balls or dumplings is concerned, after production and bagging, the bagged dumplings or glutinous rice balls need to be transported to the packing location by conveyor for centralized boxing of the bagged dumplings or glutinous rice balls.

[0004] After searching the invention patent with the authorization announcement number CN108373048B, an automatic stacking and conveying system for asphalt shingles is disclosed, which includes a shingle making machine. The shingle making machine has several discharge channels, and a conveyor is provided under each discharge channel. The key point of its technical solution is that a stacking device is provided on the conveyor for stacking asphalt shingles and releasing them at intervals for transportation on the conveyor, thereby realizing the automatic stacking and transportation of asphalt shingles, thereby achieving the purpose of reducing labor costs.

[0005] Based on the above patents and combined with existing solutions and actual production and processing, the current conveyor for bagged glutinous rice balls or dumplings still has some problems, such as:

[0006] 1. In the existing production and processing of glutinous rice balls or dumplings, the conveyor plays a relatively simple role and is only used to transport bagged dumplings or glutinous rice balls to the packing location. After transportation, the bagged dumplings or glutinous rice balls need to be manually stacked and packed. As a result, the existing conveyor has a single function and cannot realize automated stacking and packing. Manual stacking and packing operations are relatively cumbersome, increasing the workload and affecting work efficiency.

[0007] 2. In the above patent, the asphalt shingles will slide down the slope into the stacking device, and the asphalt shingles will be simply stacked by sliding down in sequence. However, the function is still relatively simple and subsequent operations after stacking cannot be realized, such as automatic packing after stacking.

[0008] Therefore, we propose a multifunctional double-layer conveyor to solve the above problems. Summary of the Invention

In addition, through the sliding cooperation between the second pin and the driving groove, the convex seat drives the push plate to reset and slide, and the push plate shrinks and slides and is stored in the convex seat. Through the reciprocating action, continuous and precise pushing and feeding of bagged dumplings or glutinous rice balls can be realized during transportation, thereby ensuring the automation performance of the conveyor.

[0034] 2. Both output ends of the bidirectional telescopic rod are provided with splint parts. The bidirectional telescopic rod can operate the two splint parts to slide in opposite directions or relative directions, and the bagged dumplings or glutinous rice balls are clamped and fixed by the two splint parts.

DETAILED DESCRIPTION

[0051] 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 creative efforts are within the scope of protection of the present invention.

[0052] Example 1:

[0053] The present invention provides a technical solution: a multifunctional double-layer conveyor, which addresses the problem that the existing conveyor has a single function and cannot realize the automatic and neat stacking processing of bagged dumplings or glutinous rice balls, and cannot realize the automatic boxing processing 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 provided 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 the bagged dumplings or glutinous rice balls are temporarily supported by the spacing support plate 10. When the stacking bracket 13 is driven to move down one unit, the spacing support plate 10 automatically releases the support, allowing the bagged dumplings or glutinous rice balls to fall into the stacking bracket 1 3, the stacking bracket 13 moves down one unit as a benchmark, and after continuous intermittent downward movement, the bagged dumplings or glutinous rice balls are supported and stacked, that is, the automatic stacking process is completed. When the stacking bracket 13 is completely moved down, the stacked bagged dumplings or glutinous rice balls are supported by the unloading support plate 16 and placed in the unloading frame 14. The stacking bracket 13 automatically releases the support and stacking, and the outer packaging box is transported to the bottom of the stacking mechanism 5 through a layer of conveyor belt 1. The unloading frame 14 is driven to move the stacked bagged dumplings or glutinous rice balls downward and insert them into the outer packaging box. After the unloading frame 14 is completely moved down, the unloading support plate 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.

[0054] This technical solution: please refer to Figures 1-13 A multifunctional double-layer conveyor includes a first-layer conveyor belt 1, which is arranged horizontally and is used to convey outer packaging boxes. The first-layer conveyor belt 1 has vertically integrated support legs on both the front and rear side casings. The support legs are placed on the work site. The first-layer conveyor belt 1 has symmetrically arranged push racks 2 on the front and rear sides for adjusting the position of the outer packaging boxes. The push racks 2 are driven on the first-layer conveyor belt 1 by a first telescopic rod 3 fixed to the first-layer conveyor belt 1 to form a sliding structure.

[0055] The conveyor belt 4 is provided with a plurality of conveyor belts 1 and a plurality of conveyor belts 1 for conveying the dumplings or glutinous rice balls. The conveyor belt 4 is provided with a plurality of conveyor belts 1 for conveying the dumplings or glutinous rice balls. The conveyor belt 4 is provided with a plurality of conveyor belts 1 for conveying the dumplings or glutinous rice balls. The conveyor belt 4 is provided with a plurality of conveyor belts 1 for conveying the dumplings or glutinous rice balls. The conveyor belt 4 is provided with a plurality of conveyor belts 1 for conveying the dumplings or glutinous rice balls. The conveyor belt 4 is provided with a plurality of conveyor belts 1 for conveying the dumplings or glutinous rice balls. The conveyor belt 4 is provided with a plurality of conveyor belts 1 for conveying the dumplings or glutinous rice balls. The conveyor belt 4 is provided with a plurality of conveyor belts 1 for conveying the dumplings or glutinous rice balls.

[0056] Specifically, in this technical solution, the second-layer conveyor belt 4 is fixedly connected to the top of the first-layer conveyor belt 1, and the bagged dumplings or glutinous rice balls are conveyed to the stacking mechanism 5 through the second-layer conveyor belt 4. Figure 1 、 Figure 4 、 Figure 12 and Figure 13 As shown, the guide plates 7 are symmetrically arranged front to back about the horizontal central axis of the second-layer conveyor belt 4. After the guide plates 7 are installed, they are fixedly connected to the casing of the second-layer conveyor belt 4 by bolts. They are arranged on the belt surface of the second-layer conveyor belt 4 in a vertical state and are parallel to the second-layer conveyor belt 4, corresponding 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 mouth facing left. Since the spacing between the two guide plates 7 is adapted to the width of the bagged dumplings or glutinous rice balls, the second-layer conveyor belt 4 enters the gap between the two guide plates 7 with the assistance of the bent ends of the guide plates 7 during the transportation of the bagged dumplings or glutinous rice balls. The bagged dumplings or glutinous rice balls are kept in the forward conveying direction by the limiting of the two guide plates 7, even if the bagged dumplings or glutinous rice balls can be accurately docked with the stacking mechanism 5 in the forward direction.

[0057] When a bagged dumpling or glutinous rice ball enters the gap between the two guide plates 7 through the second-layer conveyor belt 4, the conveying work of the second-layer conveyor belt 4 is stopped, and the current bagged dumpling or glutinous rice ball is moved to the stacking mechanism 5 through the feeding mechanism 6, and the feeding mechanism 6 is reset, and the second-layer conveyor belt 4 is started again to transport the next bagged dumpling or glutinous rice ball, and the bagged dumplings or glutinous rice balls are continuously transported to the stacking mechanism 5 in this reciprocating manner;

[0058] 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 of the main frame shell 8, and since the guide plate 7 is used to limit the position of the bagged dumplings or glutinous rice balls during transportation, it is arranged just 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 the outer shell frame 30 is placed, it is arranged in parallel with the second-layer conveyor belt 4. 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. After placement, the wide portion thereof is movably fixed 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 a movable 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 into and fixedly connected to the wide portion of the convex seat 31 by bolts. When the fourth telescopic rod 33 is started to extend and operate, 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;

[0059] Since both the front and rear sides of the wide portion of the convex seat 31 are provided with a through-state slide groove, and since both the front and rear sides of the push plate 32 are provided with a second pin 35, the push plate 32 is arranged in a square frame-shaped structure. After the push plate 32 is placed, it is movably clamped in the convex seat 31, and its lower end movably inserts through the narrow portion of the convex seat 31 to extend outward, and the front and rear second pins 35 movably insert through the front and rear slide grooves of the convex seat 31 and 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;

[0060] 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. In addition, since the pushing plate 32 is in a vertical downward extending state on the convex seat 31 when it is in a toggling state, 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 slides synchronously to the right following the convex seat 31. The lower end of the pushing plate 32 is connected to the bagged dumplings or glutinous rice balls in a toggling manner. The pushing plate 32 toggles the bagged dumplings or glutinous rice balls and conveys them to the positive limit position at the interval between the two guide plates 7 toward the stacking mechanism 5.

[0061] Since the left shell wall opening of the main frame shell 8 is provided with an integrated structure of the 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 of 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 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 is connected to the second-layer conveyor belt 4. 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, the bagged dumplings or glutinous rice balls are pushed by the pushing plate 32, and are conveyed forward by the two guide plates 7, and enter the shell cavity of the main frame shell 8 through the feeding trough 801, completing the conveyance of the bagged dumplings or glutinous rice balls to the stacking mechanism 5.

[0062] 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 grooves 36 include a horizontal slide path 3601 and an inclined slide path 3602 connected to the left end of the horizontal slide path 3601. Since the second pin 35 is screwed and fixed to the push plate 32 in a vertical state 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 shift the bagged dumplings or glutinous rice balls, the second pin 35 slides along the horizontal slide path 3601, and the horizontal slide path 3601 is set in parallel with the outer shell frame 30, keeping the push plate 32 in a vertical downward extended state on the convex seat 31, that is, keeping the push plate 32 in a shifted state;

[0063] When the push plate 32 slides downward on the convex seat 31 and extends out, the fifth spring 34 is elastically deformed by being squeezed. In addition, since the inclined chute path 3602 is arranged in an inclined upward state, and the spacing dimension between the upper end point of the inclined chute path 3602 and the horizontal chute path 3601 is equal to the maximum distance dimension of the push plate 32 when it is retracted and slides, the push plate 32 follows the convex seat 31 to slide right to complete the delivery of the bagged dumplings or glutinous rice balls to the stacking mechanism 5, and the fourth telescopic rod 33 is activated to retract and move. The rotation operation causes the convex seat 31 to drive the push plate 32 to return to the left and slide in the right section of the outer shell frame 30. At this time, the second pin 35 slides along the horizontal slide groove path 3601 to the inclined slide groove path 3602, and slides along the inclined slide groove path 3602. Through the sliding cooperation between the second pin 35 and the inclined slide groove path 3602, and through the elastic deformation of the fifth spring 34, the push plate 32 is retracted and reset to 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 retracts and slides upward and is stored in the convex seat 31, that is, the toggle state of the push plate 32 is released, and the next transportation of the second-layer conveyor belt 4 is not affected.

[0064] Specifically, in this technical solution, a stacking mechanism 5 is provided vertically downward on the right side of the second-layer conveyor belt 4, and the bagged dumplings or glutinous rice balls are automatically and neatly stacked by the stacking mechanism 5. The stacking mechanism 5 includes a main frame shell 8, a sub-frame shell 9, an interval support plate 10, a stacking bracket 13, a blanking frame 14 and a blanking support plate 16. The bagged dumplings or glutinous rice balls are temporarily supported by the interval support plate 10. Figure 3 、 Figure 4 and Figure 5 As shown, sub-frame shells 9 are provided on the front and rear side shell walls of the main frame shell 8. After the sub-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 placement, and since a connecting frame with an integrated structure is provided on the shell wall of the sub-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 sub-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 sub-frame shell 9 on the second-layer conveyor belt 4 is completed;

[0065] 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 there are spacer pallets 10 in the middle of the front and rear shell walls of the main frame shell 8, the spacer pallets 10 are arranged parallel to the feed trough 801 after being placed, and the bottom groove wall of the feed trough 801 is flush with the plate surface of the spacer pallet 10, the bagged dumplings or glutinous rice balls are transported into the shell cavity of the main frame shell 8 through the feed trough 801 by the movement of the feeding mechanism 6 and the limitation of the guide plate 7, and the front and rear sides of the bagged dumplings or glutinous rice balls are respectively overlapped on the front and rear two spacer pallets 10, and the bagged dumplings or glutinous rice balls are temporarily supported by the spacer pallets 10.

[0066] Specifically, in this 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, the pedestal frame 11 is provided with an integrated wedge-shaped strip on the side facing the linkage frame 19, wherein the wedge-shaped strip is symmetrically arranged on the pedestal frame 11, and the sub-frame shell 9 is provided with an integrated wedge-shaped strip on the side 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 in the linkage frame 19 facing the pedestal frame 11, and the longitudinal frame in 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. 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 installation, a gap is reserved between the two. After the linkage frame 19 is placed, it is movably carded 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 carded with the wedge strip in the pedestal frame 11 and the wedge 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;

[0067] Since a through-slot is provided on the upper end of the shell cavity wall of the side of the sub-frame shell 9 facing the longitudinal frame body of the linkage frame 19, the upper end of the longitudinal frame body of the linkage frame 19 is fixedly connected to a connecting frame in a vertical state by bolts. After the linkage frame 19 is installed, the connecting frame of the longitudinal frame body is movably inserted through the slot of the sub-frame shell 9 and extends 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 of the linkage frame 19 by bolts, the third telescopic rod 20 is started to retract and operate, 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;

[0068] 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, the pressure blocks 21 are connected to the outward section of the pull plate 17 by pushing and pressing, and since the longitudinal section of the pull plate 17 is a "V"-shaped structure, the section of the pull plate 17 facing the spacer support plate 10 is the inward section, and the section of the pull plate 17 away from the spacer 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 connected 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 seat cavity walls on both sides of the pedestal frame 11, and a 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 placed, 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 seat cavity wall of the pedestal frame 11. After being driven, the linkage frame 19 drives the pressure block 21 to slide downward synchronously, and the pressure block 21 pushes the outward section of the pull plate 17, so that the pull plate 17 performs a flip movement in the seat cavity of the pedestal frame 11, and the first torsion spring 18 is elastically deformed under force;

[0069] Since the upper side wall of the pressing block 21 is overlapped on the groove wall of the longitudinal frame body of the linkage frame 19 after the pressing block 21 is placed, when the pressing block 21 is subjected to force, the pressing block 21 can only be turned over by a downward thrust, and cannot be turned over by an upward thrust. Moreover, since the lower side wall of the inner section of the pulling plate 17 is overlapped on the seat cavity wall of the pedestal frame 11 after the pulling plate 17 is placed, when the outer section of the pulling plate 17 is subjected to force, the pulling plate 17 can only be turned over by a downward thrust, and cannot be turned over by an upward thrust.

[0070] Since the end of the spacer support plate 10 facing the main frame shell 8 is the inward end, and the end of the spacer support plate 10 facing the pedestal frame 11 is the outward end, a round rod parallel to the spacer support plate 10 is fixedly connected in the empty groove facing the outward end of the spacer 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 carded in the empty groove facing the outward end of the spacer support plate 10, and the round rod in the spacer support plate 10 is fixedly connected in the empty groove facing the outward end of the spacer support plate 10. The chute of the inward section of the pull plate 17 is inserted into the movable part. Since the inward section of the pull plate 17 and the spacing support plate 10 are arranged in an inclined state, the inward section of the pull plate 17 is connected to the outward 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 by sliding cooperation between the inward section of the pull plate 17 and the outward end of the spacing support plate 10.

[0071] After the pedestal frame 11 is placed, it is fixedly connected to the middle part of the shell wall of the main frame shell 8 in a vertical state by bolts. The left and right sides of the outer end of the spacer support plate 10 are provided with a limiting cylindrical portion of an integrated structure. After the spacer support plate 10 is placed, the outer end thereof together with the limiting cylindrical portion is movably clamped in the seat cavity wall of the pedestal frame 11, and the inner end thereof movably penetrates the shell wall of the main frame shell 8 and is inserted into the shell cavity of the main frame shell 8, so that the spacer support plate 10 is positioned on the pedestal frame 11 in a movable state. In addition, a first spring 1 is installed at the connection between the spacer support plate 10 and the pedestal frame 11. 2. The first spring 12 is symmetrically arranged about the vertical center axis of the spacer support plate 10. After being installed, the first spring 12 is movably inserted into the seat cavity wall of the pedestal frame 11, with one end of the first spring pressing against the limiting cylindrical portion in the spacer support plate 10 and the other end pressing against the seat cavity wall of the pedestal frame 11. After being pulled, the spacer support plate 10 shrinks and slides in the seat cavity of the pedestal frame 11, causing the first spring 12 to be elastically deformed under compression. After shrinking and sliding, the spacer support plate 10 is stored in the seat cavity of the pedestal frame 11, automatically releasing the temporary support for the bagged dumplings or glutinous rice balls.

[0072] In addition, when the pressure block 21 loses its push on the outward section of the pulling plate 17, the elastic deformation reset of the first torsion spring 18 and the elastic deformation reset of the first spring 12 are utilized to reset and flip the pulling plate 17 in the seat cavity of the pedestal frame 11, and the spacer support plate 10 loses its pull and resets, extends and slides in the seat cavity of the pedestal frame 11, and the spacer support plate 10 is re-extended into the shell cavity of the main frame shell 8 to temporarily support the next bagged dumpling or glutinous rice ball.

[0073] At the same time, in the above technical solution, according to the above, since the spacing between two adjacent pressing blocks 21 is greater than the thickness of the bagged dumplings or glutinous rice balls, the pressing blocks 21 are arranged at equal intervals from top to bottom in the longitudinal frame of the linkage frame 19, and the spacing between two adjacent pressing blocks 21 is the distance that the linkage frame 19 moves one unit. The linkage frame 19 is driven by the third telescopic rod 20 to move downward intermittently based on a unit distance, and intermittently controls the spacing support plate 10 to retract through multiple pressing blocks 21, thereby operating multiple bagged dumplings or glutinous rice balls to fall intermittently in the shell cavity of the main frame shell 8.

[0074] Specifically, in this technical solution, the stacking bracket 13 is used to support and stack the bagged dumplings or glutinous rice balls. Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9 As shown, the stacking bracket 13 is symmetrical front to back about the vertical center axis of the main frame shell 8, and is arranged just below the spacer tray 10. Since the stacking bracket 13 is arranged in a "U"-shaped structure, the horizontal plate and the two longitudinal plates located on the left and right sides of the horizontal plate, a section of the longitudinal plate in the stacking bracket 13 facing the main frame shell 8 is an "L"-shaped structure. After the stacking bracket 13 is placed, the horizontal plate is movably clamped in the frame cavity of the horizontal frame in the linkage frame 19, and the longitudinal plate movably penetrates the frame cavity of the horizontal frame in the linkage frame 19 and extends outward, so that the stacking bracket 13 is positioned on the linkage frame 19 in an active state, and the linkage frame 19 drives the stacking bracket 13 to form a synchronous lifting and sliding structure.

[0075] Since the front and rear shell cavity walls of the lower shell cavity of the main frame shell 8 are provided with through-state slide grooves, wherein the slide grooves are symmetrically arranged on the main frame shell 8, after the stacking bracket 13 is placed, the "L" section of the longitudinal plate body thereof is movably inserted through the slide groove in the main frame shell 8 and extends into the shell cavity of the main frame shell 8, and after the linkage frame 19 moves down one unit, the stacking bracket 13 follows the linkage frame 19 and also moves down based on one unit, wherein the distance of one unit is greater than the thickness of the bagged dumplings or glutinous rice balls, after the spacing support plate 10 loses its support for the bagged dumplings or glutinous rice balls, the "L" section of the longitudinal plate body in the front and rear two stacking brackets 13 is respectively overlapped on the front and rear sides of the bagged dumplings or glutinous rice balls to support the bagged dumplings or glutinous rice balls;

[0076] Since the specifications and dimensions of the frame cavity in the blanking frame 14 are the same as those of the shell cavity in the main frame shell 8, that is, the shell cavity wall in the main frame shell 8 is flush with the frame cavity wall in the blanking frame 14, and since the blanking frame 14 is placed and the movable card is set in the lower shell cavity of the main frame shell 8, the front and rear side wall of the blanking frame 14 are provided with a through state slide groove, wherein the slide groove is symmetrically arranged on the blanking frame 14, so that the slide groove in the blanking frame 14 is connected to the slide groove in the main frame shell 8, and the linkage frame 19 Drive the stacking bracket 13 to move downward intermittently, so that the stacking bracket 13 slides downward in the lower shell cavity of the main frame shell 8, and the "L" section of the longitudinal plate in the stacking bracket 13 slides along the slide groove in the unloading frame 14 and the slide groove in the main frame shell 8. After the stacking bracket 13 moves downward intermittently, the bagged dumplings or glutinous rice balls are supported and stacked on the "L" section plate of the stacking bracket 13 in turn, and the stacking bracket 13 drives the stacked bagged dumplings or glutinous rice balls into the frame cavity of the unloading frame 14.

[0077] Specifically, in this technical solution, the stacked bagged dumplings or glutinous rice balls are unloaded and supported by the unloading support plate 16. Figure 3 、 Figure 7 、 Figure 9 、 Figure 10 and Figure 11 As shown, the lower ends of the left and right frame walls of the blanking frame 14 are provided with blanking pallets 16. After being placed, the blanking pallets 16 are placed in a horizontal state in the frame cavity of the blanking frame 14. Since the width of the blanking pallet 16 is smaller than the spacing between the two stacking brackets 13 in the extended state, the stacking bracket 13 is driven by the linkage frame 19 to move completely downward, and then passes over the blanking pallet 16 and is placed under the blanking pallet 16. After the stacked bagged dumplings or glutinous rice balls are driven by the stacking bracket 13 to fall into the frame cavity of the blanking frame 14, the left and right sides of the last bagged dumpling or glutinous rice ball are respectively overlapped on the two blanking pallets 16, and the stacked bagged dumplings or glutinous rice balls are supported by the blanking pallets 16, completing the placement of the stacked bagged dumplings or glutinous rice balls in the frame cavity of the blanking frame 14.

[0078] Specifically, in this technical solution, when the stacking bracket 13 is automatically released from the supporting stacking operation, according to Figure 3 、 Figure 5 、 Figure 9 and Figure 10As shown, the left and right side walls of the shell cavity of the lower section of the sub-frame shell 9 are provided with a circular groove 23 for driving the stacking bracket 13 to automatically retract. The circular groove 23 includes a first vertical groove 2301, a horizontal groove 2302, a second vertical groove 2303 and an oblique groove 2304. Since the first pin 26 is fixedly connected to the stacking bracket 13 in a vertical state after being placed, it is symmetrically arranged on the stacking bracket 13. The two first pins 26 correspond to the two circular grooves 23 respectively. The first pin 26 and the stacking bracket 13 constitute a synchronous motion structure. Since the left and right side walls of the horizontal frame groove cavity in the linkage frame 19 are provided with a through-shaped slide groove, the first pin 26 is placed Afterwards, it movably passes through the slide groove of the horizontal frame body of the linkage frame 19 and extends outward, and its extended end is movably inserted in the circular groove 23. The first pin 26 forms a sliding structure in the circular groove 23. When the stacking bracket 13 drives the stacked bagged dumplings or glutinous rice balls to move downward, the first pin 26 moves downward 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 downward, the stacking bracket 13 is kept in a sliding and extended state on the horizontal frame body of the linkage frame 19, and the stacking bracket 13 is kept in a supporting and stacking state.

[0079] Since the tail end of the first vertical groove 2301 is connected to the head end of the horizontal groove 2302, the horizontal groove 2302 is arranged in a vertical state with the first vertical groove 2301, and is parallel to the contraction and sliding direction of the stacking bracket 13. In addition, since the limit blocks are fixedly connected on both sides of the groove cavity of the horizontal frame body of the linkage frame 19, a spring groove is provided on the longitudinal plate body of the stacking bracket 13. After the stacking bracket 13 is placed, the limit block in the linkage frame 19 is movably carded in the spring groove in 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 center axis of the stacking bracket 13. After the third spring 27 is placed, it is movably inserted into the spring groove in the stacking bracket 13, and one end thereof presses against the stacking bracket 13. When the stacking bracket 13 drives the stacked dumplings or glutinous rice balls to move down completely, the first pin 26 slides along the first vertical groove 2301 to the connection point of the first vertical groove 2301 and the transverse groove 2302, and the elastic deformation of the third spring 27 is used to reset the stacking bracket 13, so that the stacking bracket 13 is retracted and slid in the transverse frame body of the linkage frame 19, and the first pin 26 slides along the transverse groove 2302 to the connection point of the transverse groove 2302 and the second vertical groove 2303. After the stacking bracket 13 is retracted and slid, the "L" section of the longitudinal plate body in the stacking bracket 13 is stored in the slide groove of the main frame shell 8, and the stacked dumplings or glutinous rice balls placed in the frame cavity of the blanking frame 14 lose their supporting effect;

[0080] Since the tail end of the transverse groove 2302 is connected to the head end of the second vertical groove 2303, the second vertical groove 2303 is arranged in parallel with the first vertical groove 2301. Since the spacing between the second vertical groove 2303 and the first vertical groove 2301 is equal to the maximum distance of the stacking bracket 13 to be retracted and slid, 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 resets, 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 2303 to the connection point between the second vertical groove 2303 and the oblique groove 2304, keeping the stacking bracket 13 in a retracted state on the transverse frame of the linkage frame 19, without contacting the stacked bagged dumplings or glutinous rice balls, and without affecting the rising and resetting sliding of the stacking bracket 13.

[0081] Since the tail end of the second vertical groove 2303 is connected to the head end of the inclined groove 2304, the inclined groove 2304 is inclined toward the first vertical groove 2301, and since the tail end of the inclined groove 2304 is connected to the head end of the first vertical groove 2301, when the stacking bracket 13 rises and slides, the first pin 26 slides along the second vertical groove 2303 to the connection point between the second vertical groove 2303 and the inclined groove 2304, and slides along the inclined groove. The path 2304 is reset and slides to the connection point between the oblique groove path 2304 and the first vertical groove path 2301. The sliding cooperation between the first pin 26 and the oblique groove path 2304 drives the stacking bracket 13 to extend and slide on the transverse frame of the linkage frame 19. Even if the "L" section of the longitudinal plate body of the stacking bracket 13 is re-placed into the housing cavity of the main frame housing 8, the stacking bracket 13 extends and slides to reset, causing the third spring 27 to be elastically deformed after the third spring 27 is stressed.

[0082] Since a blocking block 24 for limiting the first pin 26 is provided at the connection between the first vertical groove 2301 and the oblique groove 2304, the blocking block 24 is in a "T"-shaped structure, and one end thereof facing the circular groove 23 is in an oblique tongue-shaped structure. After the blocking block 24 is placed, it is movably clamped in the shell wall of the sub-frame case 9, and its oblique tongue end is movably inserted into the connection between the first vertical groove 2301 and the oblique groove 2304, so that the blocking block 24 is positioned in the shell wall of the sub-frame case 9 in an active state. Moreover, a second spring 25 is installed at the sliding connection between the blocking block 24 and the sub-frame case 9. The second spring 25 is symmetrically arranged about the vertical center axis of the blocking block 24, one end of which presses against the blocking block 24, and the other end presses against the shell wall of the sub-frame case 9. The inclined side wall at the end is set toward the inclined groove path 2304. When the first pin 26 slides along the inclined groove path 2304 to 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 shrink and slide at the connection point between the first vertical groove path 2301 and the inclined groove path 2304, and causing the second spring 25 to be squeezed and elastically deformed. When the first pin 26 slides to the first vertical groove path 2301, the push on the blocking block 24 is lost, and the elastic deformation of the second spring 25 is used to reset, so that the blocking block 24 is reset and extended to slide at the connection point between the first vertical groove path 2301 and the inclined groove path 2304, blocking the first pin 26, so that the first pin 26 is limited in the first vertical groove path 2301.

[0083] At the same time, in the above technical solution, according to the above, since the end of the pressure block 21 is inserted and rotatably connected with the shaft column, after the pressure block 21 is placed, its end is movably clamped in the groove cavity of the longitudinal frame body in the linkage frame 19, and the two ends of the shaft column are respectively clamped and fixedly connected to the groove cavity walls on both sides of the longitudinal frame body in the linkage frame 19 by bolts, and since the second torsion spring 22 is installed at the flip connection between the pressure block 21 and the linkage frame 19, the second torsion spring 22 is symmetrically arranged about the vertical center axis of the pressure block 21. After the second torsion spring 22 is placed, it is movably sleeved on the shaft column of the pressure block 21, one end of which is clamped on the pressure block 21, and the other end of which is clamped on the groove cavity wall of the longitudinal frame body in the linkage frame 19. The part 21 is tilted downward on the longitudinal frame of the linkage frame 19, and the pressure block part 21 and the outward section of the pull plate part 17 are arranged in a mutually inclined state. When the linkage frame 19 rises and resets and slides, the pressure block part 21 is flipped by the downward push of the pull plate part 17, and the pull plate part 17 cannot flip over due to the upward push, that is, the linkage frame 19 is not blocked by the pull plate part 17 during the rising and resetting movement. After being pushed, the pressure block part 21 flips and closes on the longitudinal frame of the linkage frame 19, and the second torsion spring 22 is elastically deformed by the force. In addition, after the pressure block part 21 loses the push, the elastic deformation of the second torsion spring 22 is used to reset, so that the pressure block part 21 is reset, flipped and unfolded on the longitudinal frame of the linkage frame 19.

[0084] Specifically, in this technical solution, the stacking mechanism 5 assists in the automatic packing operation after stacking, and the blanking frame 14 drives the stacked bagged dumplings or glutinous rice balls to move down to the outer packaging box for filling operation. Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 11 As shown, the second telescopic rod 15 is composed of a telescopic rod body and a connecting rod frame, wherein 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 the left and right shell cavity walls of the lower shell cavity of the linkage plate 28 are provided with through unlocking grooves 802, the left and right sides of the upper end of the blanking frame 14 are fixedly connected with the connecting frame by bolts. After the blanking frame 14 is placed, it is movably fixed in the lower shell cavity of the main frame shell 8, and its lower end movably penetrates through the lower shell cavity opening of the main frame shell 8 to extend outward, and the connecting frame movably penetrates through the unlocking groove 802 and is placed outside the main frame shell 8. After the rod 15 is placed, the telescopic rod body is inserted into the upper shell cavity of the main frame shell 8, 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, and the stacked bagged dumplings or glutinous rice balls are placed in the frame cavity of the blanking frame 14 through the two blanking support plates 16, and the telescopic rod body in the second telescopic rod 15 is started to retract, so that the connecting rod frame in the second telescopic rod 15 drives the blanking frame 14 to move downward, so that 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;

[0085] Since push racks 2 for adjusting the position of outer packaging boxes are symmetrically arranged on the front and rear sides of the first-layer conveyor belt 1, the push rack 2 is in an "L"-shaped structure, which is divided into two parts: a horizontal frame body parallel to the first-layer conveyor belt 1 and a longitudinal frame body perpendicular to the horizontal frame body. After the push rack 2 is installed, it is vertically attached to the belt surface of the first-layer conveyor belt 1. Since the first telescopic rod 3 is symmetrically arranged front and back about the horizontal central axis of the first-layer conveyor belt 1, the two first telescopic rods 3 are respectively used for independently driving the movement of the two push racks 2. After the first telescopic rod 3 is installed, it is fixedly installed on the casing of the first-layer conveyor belt 1 by bolts, wherein the output end movably passes through the casing of the first-layer conveyor belt 1, and the output end is plugged in and fixedly connected by bolts On the transverse frame of the pushing rack 2, a layer of conveyor belt 1 drives the outer packaging box to be transported directly under the stacking mechanism 5. After the outer packaging box is transported and moved, it fits into the longitudinal frame of the pushing rack 2. The left half of the box cavity of the outer packaging box is blocked by the longitudinal frame of the pushing rack 2 so that the left half of the box cavity corresponds to the bottom of the stacking mechanism 5. The conveyor belt 1 stops conveying and drives the two first telescopic rods 3 to telescopically operate. Through the mutual cooperation of the two first telescopic rods 3, the two pushing racks 2 slide on the conveyor belt 1. The outer packaging box is clamped and fixed by the transverse frames of the two pushing racks 2, and the final position of the left half of the box cavity in the outer packaging box corresponds to the bottom of the stacking mechanism 5. At this point, the outer packaging box is docked with the stacking mechanism 5.

[0086] According to the above, when the stacking mechanism 5 places the bagged dumplings or glutinous rice balls into the outer packaging box, the unloading frame 14 first drives the stacked bagged dumplings or glutinous rice balls to move down, and then inserts them into the outer packaging box, and places the stacked bagged dumplings or glutinous rice balls at the last position of the left half of the outer packaging box. Then, the extension operation of the first telescopic rod 3 at the front is started, and the contraction operation of the first telescopic rod 3 at the rear is started, so that the push rack 2 at the front slides backward, and the push rack 2 at the rear cooperates with the push rack 2 at the front to slide backward synchronously, and the operation The position of the outer packaging box is adjusted so that the middle position of the left half of the box cavity in the outer packaging box corresponds to directly below the stacking mechanism 5, and the next batch of stacked bagged dumplings or glutinous rice balls are placed in the middle position of the left half of the box cavity in the outer packaging box by the unloading frame 14 again. Similarly, the position of the outer packaging box is adjusted again by the two pushing frames 2 so that the front position of the left half of the box cavity in the outer packaging box corresponds to directly below the stacking mechanism 5, and the next batch of stacked bagged dumplings or glutinous rice balls are placed. At this point, the placement of all bagged dumplings or glutinous rice balls in the left half of the box cavity in the outer packaging box is completed;

[0087] When the packaging box is put into the delivery box 1, the first conveyor belt 1 is moved to the delivery box 1 and the second conveyor belt 1 is moved to the delivery box 1. When the packaging box is put into the delivery box 1, the first conveyor belt 1 is moved to the delivery box 1 and the second conveyor belt 1 is moved to the delivery box 1. When the packaging box is put into the delivery box 1, the first conveyor belt 1 is moved to the delivery box 1. When the packaging box is put into the delivery box 1, the first conveyor belt 1 is moved to the delivery box 1.

[0088] Since both the front and rear sides of the lower end of the linkage plate 28 are provided with an integrated limiting cylindrical portion, the linkage plate 28 is movably clamped in the groove cavity of the middle frame wall of the blanking frame 14 after being placed, and the limiting cylindrical portions on both sides are movably clamped on the two side walls of the groove cavity of the middle frame wall of the blanking frame 14, so that the linkage plate 28 is positioned on the blanking frame 14 in an active state. When 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, it drives the linkage plate 28 to move downward synchronously;

[0089] Since the left and right side walls of the main frame shell 8 are provided with a through unlocking groove 802, the two unlocking grooves 802 correspond to the two linkage plates 28 respectively, and since the upper end of the linkage plate 28 is provided with a hook portion 2802 of an integrated structure extending outward, the hook portion 2802 is movably inserted into the unlocking groove 802 after the linkage plate 28 is placed. Since the 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 front and back about the vertical central axis of the first torsion spring 18, and the fourth spring 29 is movably inserted in the unlocking groove 802 after the fourth spring 29 is placed. In the groove cavity of the middle frame wall of the blanking frame 14, one end of the linkage plate 28 is pressed against the limiting cylindrical portion of the linkage plate 28, and the other end of the linkage plate 28 is pressed against the middle frame wall of the blanking frame 14. When the linkage plate 28 is driven to move downward, the hook portion 2802 slides downward in the unlocking groove 802. When the linkage plate 28 is driven to move completely downward, the hook portion 2802 is connected to the lower side groove wall of the unlocking groove 802 by a pressing manner, so that the linkage plate 28 is blocked from moving in the reverse direction and slides upward in the frame wall of the blanking frame 14, causing the fourth spring 29 to be squeezed and elastically deformed.

[0090] Since the lower end of the linkage plate 28 is provided with an open slot, the front and rear groove walls of the slot are provided with through slots, the end of the blanking support plate 16 is inserted through and fixedly connected with a shaft column by bolts, wherein the front and rear ends of the shaft column are fixedly clamped with bearings, and its end is movably clamped in the slot of the linkage plate 28, and the two ends of the shaft column are movably inserted through the through slots on both sides of the linkage plate 28, and the two ends of the shaft column are respectively connected with the bearings on the empty slot walls on both sides of the middle frame wall of the blanking frame 14, and since the front and rear sides of the end of the blanking support plate 16 are provided with an integrated gear part 1601, the center of the gear part 1601 coincides with the flip center of the blanking support plate 16, the blanking support plate 16 After placement, the two gear portions 1601 are movably inserted into the two through slots of the linkage plate 28, respectively. Since rack portions 2801 are provided on the front and rear through slots of the linkage plate 28, the rack portion 2801 in the linkage plate 28 on the left side is arranged in an opposite direction to the rack portion 2801 in the linkage plate 28 on the right side, and the rack portion 2801 is meshed and connected with the gear portion 1601. After the linkage plate 28 is driven to rise and slide in the frame wall of the blanking frame 14, the meshing action between the rack portion 2801 and the gear portion 1601 drives the blanking support plate 16 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.

[0091] When the unloading support plate 16 is flipped and folded and stored in the empty slot in the frame cavity of the unloading frame 14, the plate surface of the unloading support plate 16 is flush with the frame cavity wall of the unloading frame 14. After the unloading support plate 16 is flipped and folded, it loses its support for the stacked bagged dumplings or glutinous rice balls, allowing the stacked bagged dumplings or glutinous rice balls to fall through the unloading frame 14 and be filled into the outer packaging box, completing the automatic boxing process.

[0092] Example 2:

[0093] The present invention is based on the first embodiment. Figure 14-15 In the technical solution shown, after the glutinous rice balls or dumplings are bagged by the packaging equipment, they fall onto the conveyor belt of the conveyor and are transported to the stacking and boxing position of the next process. After the bagged glutinous rice balls or dumplings fall onto the conveyor belt, they are affected by various factors and the orientation of the falling conveyor belt is different. When docking with the stacking and boxing equipment in the next process, it is impossible to dock accurately. In order to deal with the problem that the existing conveyor has a single function and cannot meet the purpose of automatic adjustment of the conveying orientation, which affects the accurate docking, the two clamping parts 40 are operated by the two-way telescopic rod 38 to clamp the bagged dumplings or glutinous rice balls, and the two-way telescopic rod 38 is driven to rotate by the servo motor 39 to adjust the position of the bagged dumplings or glutinous rice balls in the positive direction.

[0094] Specifically, in this technical solution, when performing the positive adjustment operation of the position of the bagged dumplings or glutinous rice balls, according to Figure 14 and Figure 15As shown, the carrier 37 is placed on the left side of the guide plate 7. After being placed, 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 by bolts (the image collector 41 is a prior art, and the docking method of the image collector 41 and the central processing unit is also a prior art, which will not be described in detail in the specification), the image collector 41 is placed directly above the second-layer conveyor belt 4. When the second-layer conveyor belt 4 is conveying bagged dumplings or glutinous rice balls, the image collector 41 collects images of the bagged dumplings or glutinous rice balls, enters the images into the central processing unit, identifies the position features of the bagged dumplings or glutinous rice balls, calculates the coordinate deviation between the target position and the standard position, and starts the two-way telescopic rod 38 and the servo motor 39 to operate respectively through the central processing unit;

[0095] Since the two output ends of the two-way telescopic rod 38 are both provided with clamping plates 40, the clamping plates 40 are sleeved and fixedly connected to the output ends of the two-way telescopic rod 38 by bolts after being installed, and are in a vertical downward state, the two-way telescopic rod 38 is started to retract and operate, so that the sliding directions of the two clamping plates 40 are set in opposite directions, and the two clamping plates 40 are used to clamp the bagged dumplings or glutinous rice balls;

[0096] Since the upper side of the bidirectional telescopic rod 38 is fixedly mounted on the connecting frame by bolts, an integrated shaft column is vertically arranged in the middle of the connecting frame, and a bearing is fixedly clamped on the shaft column, the bidirectional telescopic rod 38 is placed on the lower side of the carrier frame 37 after installation, wherein the shaft column of the connecting frame and the bearing are inserted into the middle of the carrier frame 37. Since the servo motor 39 is placed on the upper side of the carrier frame 37, it is fixedly mounted on the middle of the carrier frame 37 by bolts after installation, and the output end is inserted and fixedly connected to the shaft column of the connecting frame in the linkage plate 28 by bolts, the servo motor 39 is started to operate, and the bidirectional telescopic rod 38 is driven by the servo motor 39 to rotate the bidirectional telescopic rod 38 in the middle of the carrier frame 37, and the clamping plate 40 clamps the bagged dumplings or glutinous rice balls for positive position adjustment, ensuring that the second-layer conveyor belt 4 drives the bagged dumplings or glutinous rice balls to be accurately transported to the gap between the two guide plates 7.

[0097] This is the entire working process of the multifunctional double-layer conveyor. Contents not described in detail in this specification belong to the existing technology well known to professional and technical personnel in this field.
