[0033] A bottom pressing and sealing mechanism is also provided on the front side of the bottom heating mechanism and above the front end of the fixed connection seat 13. The bottom pressing and sealing mechanism includes a bottom pressing and sealing plate 25 for pressing and sealing the bottom of the pre-folded packaging paper box 12. The bottom pressing and sealing plate 25 is connected to the telescopic part at the lower end of the pressing and sealing cylinder 24 provided on the cylinder fixing frame 20, so that the pressing and sealing cylinder 24 provided on the cylinder fixing frame 20 is used to drive the bottom pressing and sealing plate 25 to move up and down, thereby pressing and sealing the bottom of the pre-folded packaging paper box 12 that has been heated and pre-folded on the paper box core mold 16 and moves to the bottom of the bottom pressing and sealing mechanism together with the bottom making sliding seat 15.

[0034] At the same time, a bottom folding swing mechanism 18 is also provided on the bottom making sliding seat 15 and on the rear side of the paper box core mold 16; accordingly, a bottom folding fixed guide plate 23 is provided between the bottom heating mechanism and the bottom pressing and sealing mechanism. The bottom folding fixed guide plate 23 is composed of a horizontally arranged guide plate body 43, one end of which is connected to the cylinder fixing frame 20 through a guide plate fixing portion 44, and the other end of the guide plate body 43 is provided with a bottom folding oblique edge 45.

The bottom folding swing frame 27 is composed of a swing frame hinge shaft 35. The two ends of the swing frame hinge shaft 35 are respectively provided with long rod support arms 36 extending upward. A bottom folding long rod 37 is arranged between the front ends of the two long rod support arms 36. The two ends of the bottom folding long rod 37 are respectively connected to the front ends of the long rod support arms 36. The bottom folding swing frame 27 is rotated on the swing frame hinge part 34 at the upper end of the bottom folding support frame 26 through the swing frame hinge shaft 35, and the bottom folding long rod 37 that can swing back and forth is arranged at the front end of the two long rod support arms 36 to pre-fold the rear side of the bottom folding plate of the packaging paper box 12 installed on the paper box core mold 16.

[0036] A swing frame reset spring 30 is provided between the folding bottom swing frame 27 and the folding bottom support frame 26 of the folding bottom swing mechanism 18. One end of the swing frame reset spring 30 is connected to a reset spring connection column 40 provided on the swing frame hinge shaft 35 of the folding bottom swing frame 27; the other end of the swing frame reset spring 30 is connected to the lower part of the folding bottom support frame 26. In addition, a swing frame limit stopper 31 for limiting the swing position of the folding bottom swing frame 27 is also provided on the upper part of the support body 32 of the folding bottom support frame 26; the swing frame reset spring 30 is used to assist the folding bottom swing frame 27 to reset after swinging around the swing frame hinge 34 at the upper end of the folding bottom support frame 26, and the swing frame limit stopper 31 is used to limit the swing position of the folding bottom swing frame 27, so as to ensure the reliability of the device.

[0037] At least one of the long rod arms 36 at both ends of the swing frame hinge shaft 35 of the bottom folding swing frame 27 is provided with a toggle extension rod 38, and the toggle extension rod 38 is arranged in a direction opposite to the extension direction of the long rod arms 36. Correspondingly, a vertically arranged toggle block fixing frame 28 is also provided on one side of the middle part of the fixed connection seat 13 corresponding to the toggle extension rod 38; and a swing frame toggle block 29 is fixedly provided on the upper part of the toggle block fixing frame 28. Thus, the toggle extension rod 38 on the bottom folding swing frame 27 hinged on the upper part of the bottom folding support frame 26, which moves along with the bottom making sliding seat 15, is toggled by using the swing frame toggle block 29 fixedly provided on the upper part of the toggle block fixing frame 28, so as to drive the bottom folding swing frame 27 to swing downward and press the bottom of the packaging paper box 12.

[0038] In order to improve the service life of the device, a one-way toggle rotating block 39 for contacting the swing frame toggle block 29 is provided at the lower end of the toggle extension rod 38 of the folding bottom swing frame 27. One end of the one-way toggle rotating block 39 is hinged to the rotating block hinge part 41 at the end of the toggle extension rod 38, and the rotating block hinge part 41 of the toggle extension rod 38 is also provided with a one-way toggle limiting card slot 42 for limiting the rotation direction of the one-way toggle rotating block 39, that is, the one-way toggle rotating block 39 can only form a rigid contact with the swing frame toggle block 29 on one side to drive the folding bottom swing frame 27 to swing; when the other side of the one-way toggle rotating block 39 contacts the swing frame toggle block 29, since there is no one-way toggle limiting card slot 42 to fix it, the one-way toggle rotating block 39 will rotate around the rotating block hinge part 41 (such as Figure 6 As shown). After the bottom of the packaging paper box 12 is sealed, the paper box core mold 16 and the bottom folding swing mechanism 18 move back to the initial paper box pick-up and placement station along with the bottom making sliding seat 15. By moving the one-way toggle rotating block 39 at the lower end of the extension rod 38 and the one-way rotation contact of the swing frame toggle block 29 at the upper part of the toggle block fixing frame 28, the number of reciprocating toggle of the bottom folding swing frame 27 is effectively reduced.

[0039] At the other end of the frame 1, a chain linear conveying mechanism 5 for unidirectionally conveying a plurality of packaging cartons 12 is provided. The chain linear conveying mechanism 5 includes two groups of chain guide brackets 46 arranged in parallel, and a fixed support 47 is provided at the lower part of the chain guide bracket 46. A carton conveying chain 48 is provided on each of the two groups of chain guide brackets 46 arranged in parallel, and a carton pushing space 67 for linearly conveying the packaging cartons 12 is provided between the two carton conveying chains 48. The carton conveying chains 48 are each composed of an annular upper chain 52 and an annular lower chain 53, and the annular lower chain 53 is located directly below the annular upper chain 52. The annular upper chain 52 and the annular lower chain 53 arranged in upper and lower positions are connected by a plurality of groups of chain connecting plates 54 arranged along the extending direction of the chains. The chain connecting plate 54 is composed of a vertically arranged connecting plate 56, and chain link connecting parts 57 are respectively provided at the upper and lower ends of the connecting plate 56; the connecting plate 56 is connected to the chain links of the annular upper chain 52 and the annular lower chain 53 through the chain link connecting parts 57 at both ends, and then the chain connecting plate 54 is used to connect the annular upper chain 52 and the annular lower chain 53 into one, so as to facilitate the driving sprocket assembly 49 to synchronously drive the annular upper chain 52 and the annular lower chain 53 of the paper box conveying chain 48.

[0040] On the circular upper chain 52 and the circular lower chain 53 of the carton conveying chain 48, and between two adjacent groups of chain connecting plates 54, there are also carton pushing plates 55 for driving the packaging carton 12 to move. The carton pushing plate 55 is composed of a pushing flat plate 58, and the upper and lower ends of the pushing flat plate 58 are respectively provided with chain link connecting parts 57, and between the two chain link connecting parts 57 and the outer side of the pushing flat plate 58, there are two groups of vertically and symmetrically arranged pushing folding plates 59; and the two ends of each group of pushing folding plates 59 are respectively provided with pushing plate bending ends 60 bent toward the middle, so as to facilitate the pushing of the packaging carton 12 by the carton pushing plate 55 and prevent the pushing folding plates 59 from damaging the packaging carton 12. The pushing flat plate 58 of the carton pushing plate 55 is connected to the chain links of the circular upper chain 52 and the circular lower chain 53 through the chain link connecting parts 57 at both ends. Thus, two sets of adjacent carton pushing plates 55 on the carton conveying chains 48 on both sides in the carton pushing space 67 are used to position and clamp the packaging carton 12 to be conveyed, and the packaging carton 12 is driven to move in a straight line in one direction by the carton pushing plates 55 that move in a circular motion with the continuous rotation of the annular upper chain 52 and the annular lower chain 53.

[0041] At the same time, one end of the annular upper chain 52 and the annular lower chain 53 of the two groups of paper box conveying chains 48 is provided with a driving sprocket assembly 49. The driving sprocket assembly 49 is composed of a vertically arranged driving sprocket shaft 61, and the upper part of the driving sprocket shaft 61 is respectively provided with an upper chain driving sprocket 62 and a lower chain driving sprocket 63 for connecting with the annular upper chain 52 and the annular lower chain 53 from top to bottom. The lower part of the driving sprocket shaft 61 is respectively provided with a driving gear 64 and a transmission gear 65 for connecting the two driving sprocket assemblies 49; the middle part of the driving sprocket shaft 61 is provided with a bearing connecting plate 66; and then the driving sprocket assembly 49 is connected to the rotating bearing through the bearing connecting plate 66, and the driving device connected to the driving gear 64 is used to drive the driving sprocket shaft 61 to rotate, and the mutually meshing transmission gear 65 is used to transmit power to the adjacent driving sprocket assembly 49. Thus, the upper chain driving sprocket 62 and the lower chain driving sprocket 63 drive the endless upper chain 52 and the endless lower chain 53 of the paper box conveying chain 48 to rotate continuously.

[0042] The other end of the annular upper chain 52 and the annular lower chain 53 of the two groups of paper box conveying chains 48 is provided with a tensioning sprocket assembly 50. The tensioning sprocket assembly 50 is composed of a vertically arranged tensioning wheel rotating shaft 68, and the upper and lower ends of the tensioning wheel rotating shaft 68 are respectively provided with an upper chain tensioning sprocket 69 and a lower chain tensioning sprocket 70. In addition, the middle part of the tensioning wheel rotating shaft 68 is rotatably arranged at one end of a tensioning telescopic frame 71; the other end of the tensioning telescopic frame 71 is telescopically arranged in a tensioning elastic seat 72, and a tensioning spring is also arranged between the end of the tensioning telescopic frame 71 and the inner cavity of the tensioning elastic seat 72. A fixed column 73 is arranged at the lower part of the tensioning elastic seat 72. Then, the tensioning sprocket assembly 50 is connected to the annular upper chain 52 and the annular lower chain 53 of the carton conveying chain 48 by utilizing the upper chain tensioning sprocket 69 and the lower chain tensioning sprocket 70 provided on the tensioning wheel rotating shaft 68, and the carton conveying chain 48 is tensioned by the tensioning telescopic frame 71 telescopically arranged in the tensioning elastic seat 72, thereby ensuring the stability and reliability of the chain transmission.

In addition, a filling device 8 for filling materials into the packaging paper box 12 is provided above the middle of the chain linear conveying mechanism 5, and the feeding end of the filling device 8 is connected to the discharging end of the filling material tank 9 provided on the top of the frame 1 through a conveying pipeline. At the same time, a filling lifting mechanism 7 for lifting the packaging paper box 12 during the filling process is also provided below the filling device 8 and the lower side of the chain linear conveying mechanism 5. A top pre-folding mechanism 6 is provided on one side of the filling device 8 close to the paper box entrance of the chain linear conveying mechanism 5 and above the chain linear conveying mechanism 5; a top heating device 10 and a top pressing and sealing mechanism 11 arranged along the conveying direction of the packaging paper box 12 are provided in sequence on the other side of the filling device 8 and above the chain linear conveying mechanism 5.

[0044] When the semi-automatic carton filling equipment is used, first, the carton shifting cylinder 17 of the carton packaging bottom making device 2 at one end of the frame 1 is in a fully extended state, and the bottom making sliding seat 15 is located at the initial carton picking and placing station (such as Figure 2 Then, the operator sets the packaging paper box 12 to be made into a bottom, with the bottom facing upward, on the paper box core mold 16 of the bottom making sliding seat 15. Then, the paper box shifting cylinder 17 is retracted to a certain length, thereby driving the bottom making sliding seat 15, together with the paper box core mold 16 and the packaging paper box 12 thereon, to move forward along the bottom making slide rail 14 to below the bottom heating air box 22 of the bottom heating mechanism (as shown in FIG. Figure 2Afterwards, the bottom heating wind box 22 is driven downward by the wind box lifting cylinder 21 disposed on the cylinder fixing frame 20 to preheat the bottom folding plate of the packaging paper box 12 on the paper box core mold 16 below before pre-folding.

[0045] After the bottom of the packaging carton 12 is preheated, the wind box lifting cylinder 21 of the carton packaging bottom making device 2 drives the bottom heating wind box 22 to move upward; then, the carton shifting cylinder 17 is completely retracted, driving the bottom making sliding seat 15 together with the carton core mold 16 and the packaging carton 12 thereon to move to the bottom sealing plate 25 of the bottom sealing mechanism (such as Figure 8 As shown). In addition, during the process of the bottom making sliding seat 15 moving from the bottom heating mechanism to the bottom pressing and sealing mechanism, the bottom folding swing frame 27 hinged on the top of the bottom folding support frame 26, which moves along with the bottom making sliding seat 15, is moved by the swing frame toggle block 29 fixedly arranged on the top of the toggle block fixing frame 28. Thus, the bottom folding swing frame 27 swinging downward and the bottom folding fixed guide plate 23 fixedly arranged between the bottom heating mechanism and the bottom pressing and sealing mechanism are used to pre-fold the front and rear sides of the bottom folding plate of the packaging paper box 12 sleeved on the paper box core mold 16 before pressing and sealing.

[0046] When the bottom of the preheated and pre-folded packaging paper box 12 moves to the bottom of the bottom pressing and sealing mechanism together with the bottom making sliding seat 15 of the paper box packaging bottom making device 2, the bottom pressing and sealing plate 25 is driven downward by the pressing and sealing cylinder 24 arranged on the cylinder fixing frame 20 to press and seal the bottom of the packaging paper box 12 on the paper box core mold 16. After the bottom making of the packaging paper box 12 is completed, the pressing and sealing cylinder 24 drives the bottom pressing and sealing plate 25 to move upward; then, the paper box shifting cylinder 17 is fully extended again, and the bottom making sliding seat 15 together with the paper box core mold 16 and the packaging paper box 12 thereon are pushed back to the initial paper box picking and placing station, and the packaging paper box 12 with the bottom made is removed, so as to prepare for the next operation cycle of the bottom making of the packaging paper box 12.

[0047] Subsequently, the operator places the bottom-made packaging paper box 12 on the ultrasonic capping mechanism 3, and then installs a cap on the top of the packaging paper box 12. At the same time, the conveying drive device connected to the driving gear 64 of one of the driving sprocket assemblies 49 of the chain linear conveying mechanism 5 is used to drive the driving sprocket shaft 61 to rotate, and the mutually meshing transmission gear 65 is used to transmit power to another adjacent driving sprocket assembly 49 (reverse rotation); and then the upper chain driving sprocket 62 and the lower chain driving sprocket 63 of the two driving sprocket assemblies 49 respectively drive the two sets of paper box conveying chains 48 (annular upper chain 52 and annular lower chain 53) to rotate continuously in opposite directions. Afterwards, the packaging paper box 12 with the lid installed on the top is put into the middle paper box pushing space 67 through the paper box entrances at one end of the two paper box conveying chains 48 of the chain linear conveying mechanism 5 in turn, and the packaging paper box 12 is positioned and clamped by two sets of adjacent paper box pushing plates 55 on the paper box conveying chains 48 on both sides in the paper box pushing space 67. The paper box pushing plates 55 that move in a circle with the continuous rotation of the annular upper chain 52 and the annular lower chain 53 drive the packaging paper box 12 to move in a straight line in one direction, thereby realizing accurate, smooth and continuous conveying of the packaging paper box 12.

[0048] When the packaging carton 12 moves to the bottom of the top pre-folding mechanism 6, the carton conveying chain 48 of the chain linear conveying mechanism 5 temporarily stops rotating, and after the top pre-folding mechanism 6 pre-folds and arranges the top opening of the packaging carton 12, the chain linear conveying mechanism 5 continues to operate. When the packaging carton 12 with the top pre-folded moves to the bottom of the filling device 8, the chain linear conveying mechanism 5 stops again; then, the filling lifting mechanism 7 lifts the packaging carton 12. As the filling device 8 gradually fills the packaging carton 12 with materials, the filling lifting mechanism 7 slowly falls with the packaging carton 12. The packaging carton 12 that has been filled continues to move to the bottom of the top heating device 10 with the chain linear conveying mechanism 5, and the top of the packaging carton 12 is preheated; then, the top sealing mechanism 11 is used to seal the preheated top of the packaging carton 12. The packaging carton 12 with the material filled inside after the top is pressed and sealed is finally taken out through the carton outlet at the front end of the carton pushing space 67 of the chain linear conveying mechanism 5, and then transported to the next process.
