Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, and particularly to an equipment for opening and forming packaging cartons. Background Art

[0002] A packaging carton is a carton used to store packaged products during the packaging process. Before packaging products with the packaging carton, it is necessary to perform an unpacking process, unfold the folded packaging carton and perform plugging. After the packaging carton is formed, generally, a fixture is used to clamp the formed packaging carton, and then it is moved to a transmission mechanism for transmission. The fixture is mainly composed of two groups of clamping plates. Generally, the two groups of clamping plates are brought closer to contact the outer side of the packaging carton to clamp the packaging carton. However, since the inside of the packaging carton is empty and lacks support, when the clamping plates contact the outer side of the packaging carton, if the clamping force on the packaging carton is large, it is easy to cause the packaging carton to deform. If the clamping force on the packaging carton is small, it is easy to cause instability or inability to clamp when the fixture clamps the packaging paper. Summary of the Invention

[0003] The purpose of the present invention is to provide an equipment for opening and forming packaging cartons to solve the problem that the inside of the packaging carton is empty and lacks support as mentioned in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An equipment for opening and forming packaging cartons, including: a workbench and a stock storage mechanism, a transmission mechanism, a driving mechanism, a pressing mechanism, a material taking mechanism, and an upward pushing mechanism arranged on the workbench.

[0025] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1:

[0027] Please refer to Figure 1 , Figure 2 and Figure 3, A carton unpacking and forming device for packaging, comprising: a workbench 1, a material storage mechanism 2, a transmission mechanism 3, a driving mechanism 4, a pressing mechanism 8, and a material taking mechanism 9 provided on the workbench 1. An installation seat 6 is provided on the moving end of the driving mechanism 4, and two groups of clamping plates 7 are slidably provided on the installation seat 6; the material storage mechanism 2 refers to a placement platform on which the cartons to be unpacked are placed for caching (the placed cartons refer to unfolded folded cartons). A blocking mechanism 5 is slidably provided above the workbench 1, and the blocking mechanism 5 is located at the outlet of the material storage mechanism 2 and is used to block the cartons so that the cartons are stacked inside the material storage mechanism 2; the material taking mechanism 9 refers to a manipulator with suction cups that adsorbs a folded carton at the material storage mechanism 2 and then moves it to the processing area (when taking the folded carton, the blocking mechanism 5 moves to open the outlet of the material storage mechanism 2); the pressing mechanism 8 refers to a pressing plate and a power mechanism (used to drive the pressing plate to move and apply a squeezing force to both sides of the carton to unfold the folded cartons, changing the cartons from a one - character shape to a mouth - shape); the driving mechanism 4 is composed of a guide rail and a sliding seat. The sliding seat slides on the guide rail, the installation seat 6 is installed on the sliding seat, and a cylinder is installed on the installation seat 6 to drive the two groups of clamping plates 7 to approach or separate; above the workbench 1, there is a top - up mechanism (the top - up mechanism includes a jacking part and a closing part; the jacking part is composed of a cylinder and a pressing block installed on the moving end of the cylinder, and the closing part is composed of a flap rotatably installed on the workbench 1 and a motor used to drive the flap to rotate. There are four groups of the closing parts, respectively located around the jacking part; the closing part moves the cardboard below the side wall of the unfolded carton towards the bottom of the carton, and then the jacking part jacks up the closed cardboard upwards so that the cardboard is inserted together to seal the bottom of the carton and complete the forming process of the carton).

[0028] Please refer to Figure 2 and Figure 4 , An expansion member 11 is installed on the installation seat 6, and an installation member 10 is provided on the moving end of the expansion member 11. The installation member 10 is located between the two groups of clamping plates 7. The expansion member 11 drives the installation member 10 to move to adjust the position of the installation member 10 so that the installation member 10 moves above the formed carton; an accommodation groove is opened below the installation member 10, and an installation plate 12 is slidably inserted into the accommodation groove. An expansion mechanism is installed in the inner cavity of the accommodation groove, and the moving end of the expansion mechanism is connected to the installation plate 12; on the side of the installation plate 12 facing the clamping plate 7, there are two groups of slotted openings. A support plate 14 is slidably inserted into the inner cavity of the slotted openings, and a driving member is provided in the inner cavity of the slotted openings. The driving member is connected to the support plate 14 to drive the support plate 14 to approach or separate from the clamping plate 7.

[0029] In this embodiment, as Figure 4 and Figure 6As shown in the figure, a storage hole is provided on the side of the support plate 14 away from the mounting plate 12. A guiding member is slidably inserted into the inner cavity of the storage hole (the moving direction of the guiding member is the same as the moving direction of the support plate 14). A spring member is provided between the storage hole and the guiding member; a pressing plate 141 is provided at one end of the guiding member away from the support plate 14. A touch switch is provided on the support plate 14. The touch switch is located between the support plate 14 and the pressing plate 141. The touch switch is electrically connected to the driving member through a wire; during the process of the driving member driving the support plate 14 to move closer to the inner side wall of the paper box, the pressing plate 141 will contact the inner side wall of the paper box, and the pressing plate 141 will move closer to the support plate 14, squeezing the touch switch, causing the driving member to stop working, so that the support plate 14 and the pressing plate 141 stop moving, avoiding excessive pressure on the paper box caused by the support plate 14.

[0030] In summary, during the unpacking process of the paper box, the blocking mechanism 5 moves. After opening the outlet of the material storage mechanism 2, the material taking mechanism 9 works to suck the paper box on the material storage mechanism 2 and move the paper box to the processing area on the workbench 1; then the pressing mechanism 8 works to apply pressure to both sides of the paper box. After the paper box is unfolded, the upward pushing mechanism works to push the lower cardboard of the paper box upward, so that the cardboard is inserted together to seal the lower part of the paper box and form the paper box; then the driving mechanism 4 drives the mounting seat 6 to move. After moving the two sets of clamping plates 7 to both sides of the paper box, the air cylinder on the mounting seat 6 works to make the clamping plates 7 move closer to and contact the formed paper box; at the same time, after the telescopic mechanism drives the mounting plate 12 to move downward and insert into the interior of the formed paper box, the driving member works to make the support plate 14 move to contact the inner side wall of the paper box and support the inner side of the paper box (the contact area between the support plate 14 and the formed paper box is the area where the formed paper box is pressed by the clamping plate 7); then the driving mechanism 4 drives the mounting seat 6 to move. After moving the clamped paper box above the transmission mechanism 3, the clamping plate 7 and the support plate 14 release the paper box, so that the paper box falls onto the transmission mechanism 3 and is transported away; repeat the operation to process other paper boxes.

[0031] Embodiment 2:

[0032] Please refer to Figure 4 , an insertion block 13 is provided below the mounting plate 12. The insertion block 13 is a triangle with the corner facing downwards; during the process of the pressing mechanism 8 squeezing both sides of the paper box to unfold the paper box, the telescopic mechanism drives the mounting plate 12 to move downward, so that the insertion block 13 is inserted into the folded paper box, applying an outward force to the folded paper box from the inside to assist in unfolding the paper box, avoiding excessive force on the paper box caused by only pressing with the pressing mechanism 8 and avoiding deformation of the paper box caused thereby.

[0033] In this embodiment, as Figure 5As shown in the figure, the insertion block 13 is slidably installed below the mounting plate 12, and the moving path of the insertion block 13 is the same as the moving direction of the mounting seat 6; an opening is provided on the side wall of the mounting plate 12, and a moving member 16 is slidably inserted into the inner cavity of the opening. The moving member 16 is connected to the insertion block 13. By moving the moving member 16, the insertion block 13 is driven to move. An elastic member 17 is provided between the moving member 16 and the opening, and a connecting rope 15 is provided between the moving member 16 and the mounting member 10; during the process of the telescopic mechanism driving the mounting plate 12 to move downward, the distance between the mounting plate 12 and the mounting member 10 becomes larger and larger, which will cause the connecting rope 15 to drive the moving member 16 to move, driving the insertion block 13 to move below the mounting plate 12 and move closer to the side wall of the paper box (this side wall is the side pressed by the pressing mechanism 8), so as to limit the moving amplitude of the pressing mechanism 8 and prevent the paper box from deforming due to the too large moving amplitude of the pressing mechanism 8.

[0034] In this embodiment, as Figure 4 , Figure 5 , Figure 7 and Figure 8 , a push block 18 is hinged to the side of the insertion block 13 facing the clamping plate 7, and a return spring is installed between the push block 18 and the insertion block 13; an installation groove 20 is provided on the side of the insertion block 13 facing the clamping plate 7, and the installation groove 20 is located below the push block 18. A pressure block 19 is slidably inserted into the installation groove 20 (one end of the pressure block 19 away from the insertion block 13 is outside the installation groove). The lower side of the side of the pressure block 19 facing the clamping plate 7 is an inclined surface. An elastic element is provided between the installation groove 20 and the pressure block 19. An installation hole 21 is provided on the side of the insertion block 13 facing the clamping plate 7, and a linkage mechanism 22 connected to the pressure block 19 is provided in the installation hole 21;

[0035] As Figure 8 shown, the linkage mechanism 22 includes an installation sleeve 221 and a push rod 222 slidably inserted into the installation sleeve 221. One end of the push rod 222 away from the installation sleeve 221 is attached to the side wall of the push block 18 close to the insertion block 13; an electromagnet is provided in the installation sleeve 221, and a magnetic block is provided on the inner end of the push rod 222. The magnetic poles of the magnetic block and the electromagnet on the side close to each other are the same. A touch switch electrically connected to the electromagnet is provided in the installation groove 20; when the insertion block 13 is inserted into the paper box to assist in opening the paper box, the pressure block 19 contacts the inner wall of the paper box, squeezes the pressure block 19 into the installation groove 20, causes the pressure block 19 to press the touch switch, makes the electromagnet energized to generate a magnetic force that repels the magnetic block, moves the push rod 222 outward, makes the push block 18 rotate away from the insertion block 13, applies pressure to the inside of the paper box, and increases the squeezing amplitude of the insertion block 13 on the inside of the paper box in cooperation with the push block 18, enhancing the ability to assist in opening the paper box.

[0036] As Figure 8As shown, the linkage mechanism 22 can also be composed of a mounting sleeve 221 and a push rod 222 slidably inserted into the mounting sleeve 221. One end of the push rod 222 away from the mounting sleeve 221 is in contact with one side wall of the push block 18 close to the insertion block 13, and a pull rope is provided between the pressing block 19 and the push rod 222. During the process of the pressing block 19 moving towards the inside of the mounting groove 20, the pull rope will be pulled, driving the push rod 222 to move outwards, pushing the push block 18, and causing the push block 18 to rotate to apply pressure to the inside of the paper box.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
