[0026] The following combines the attached Figures 1-4 Further detailed description is made for this application.

[0027] The embodiment of this application discloses a fully automatic adjustable carton corner pasting device.

[0028] Refer to Figure 1 , the fully automatic adjustable carton corner pasting device includes a frame 1, a pressing and pasting assembly 2, a conveyor assembly 3, a carton tray 4, a driving member 5 and an adjusting assembly 6. The pressing and pasting assembly 2 is installed on the frame 1, and the pressing and pasting assembly 2 is used to paste the tape on the carton. The conveyor assembly 3 is installed on the frame 1, and the conveyor assembly 3 is used to convey the tape. The carton tray 4 is installed on the frame 1, the driving member 5 is installed on the frame 1, the driving member 5 is used to drive the carton tray 4 to move, and the adjusting assembly 6 is installed on the carton tray 4, and the adjusting assembly 6 is used to adapt to cartons of different specifications.

[0029] When using this adjustable carton corner pasting device, first, according to the carton specifications, the carton tray 4 is adjusted through the adjusting assembly 6 to adapt to the carton size. Then, the carton with cut slots is placed on the carton tray 4. The driving member 5 is started to drive the carton tray 4 to move and convey the carton to the designated position. At this time, the conveyor assembly 3 starts to work and conveys the tape to the predetermined position. Immediately afterwards, the pressing and pasting assembly 2 acts to accurately paste the tape on the carton corners. The driving member 5 drives the carton tray 4 to rotate, and the corner pasting operation is sequentially completed for each end connection area after the carton is folded. The corner pasting process does not require frequent manual intervention, realizing a fully automated process from carton specification adjustment to corner pasting completion, which is efficient and stable.

[0030] Refer to Figure 1 and Figure 2, the pressing component 2 includes a support frame 21, a slide rail 22, an electric cylinder 23, a sliding block 24, a pressing block 25, and a cutting knife 26. The support frame 21 is fixedly installed on the machine frame 1. In the embodiment of the present application, the support frame 21 is composed of multiple steel plates connected by bolts. The slide rail 22 is vertically arranged and slidably installed on the support frame 21, and the sliding direction is along the height direction of the support frame 21. The fixed end of the electric cylinder 23 is fixedly installed on the slide rail 22. The sliding block 24 is slidably arranged on the slide rail 22, and the sliding direction is the same as the sliding direction of the slide rail 22. The sliding block 24 is fixedly connected to the output end of the electric cylinder 23. The pressing block 25 is slidably installed on the sliding block 24. A pressing notch is formed on the pressing block 25, and the pressing notch has an inverted V-shaped right-angle structure. The cutting knife 26 is fixedly installed on the sliding block 24. The pressing block 25 is arranged in parallel with the cutting knife 26 and is in contact with each other.

[0031] When using the carton corner pasting device, first, according to the height of the carton, slide and adjust the pressing component 2 along the height direction on the support frame 21 through the slide rail 22 to adjust the pressing component 2 to a suitable initial position. Start the electric cylinder 23, and the electric cylinder 23 drives the sliding block 24 to slide downward along the slide rail 22, driving the pressing block 25 and the cutting knife 26 to move downward synchronously. When the pressing block 25 approaches the corner of the carton, the pressing notch on the pressing block 25 precisely fits the contour of the carton corner. As the sliding block 24 continues to move downward, the pressing block 25 tightly presses the tape on the carton to ensure that the tape is in full contact with the carton surface and is closely attached. After the tape pressing is completed, the electric cylinder 23 continues to push the sliding block 24, causing the cutting knife 26 to continue to move downward and the pressing block 25 to slide upward relative to it to cut the tape. A complete corner pasting operation is completed. Subsequently, the electric cylinder 23 drives the sliding block 24 to drive the pressing block 25 and the cutting knife 26 to move upward and reset, waiting for the next corner pasting task. The whole process is precise and efficient, ensuring the quality and efficiency of carton corner pasting.

[0032] Refer to Figure 1 and Figure 2The conveying assembly 3 includes a tape storage wheel 31, a rotating shaft 32, a tape outlet block 33, a tape guide frame 34, a driving wheel 35, a first motor 36, and a driven wheel 37. The tape storage wheel 31 is rotatably mounted on the support frame 21, the axis of the tape storage wheel 31 is perpendicular to the sliding direction of the sliding block 24, and the tape storage wheel 31 and the clamping notch are located in the same plane, the rotating shaft 32 is horizontally arranged, the rotating shaft 32 is rotatably mounted on the support frame 21, and the axis of the rotating shaft 32 is perpendicular to the sliding direction of the sliding block 24, the tape outlet block 33 is fixedly mounted at the bottom of the sliding block 24, and a tape outlet port is provided on the tape outlet block 33, and the tape outlet port is adapted to the position of the clamping notch, and one end of the tape guide frame 34 is rotated. The belt guide frame 34 is provided with a guide groove, and the driving wheel 35 is rotatably arranged on the belt guide frame 34. The axis of the driving wheel 35 is perpendicular to the belt guide frame 34. The fixed end of the first motor 36 is fixedly connected to the support frame 21 through a connecting frame, and the output end of the first motor 36 is coaxially fixedly connected to the driving wheel 35. The driven wheel 37 is rotatably installed on the belt guide frame 34, and the driven wheel 37 is frictionally connected to the driving wheel 35.

[0033] When using the carton corner pasting device, a sufficient amount of tape is pre-wound on the tape storage wheel 31, one end of the tape passes through the guide groove on the tape guide frame 34, enters between the driving wheel 35 and the driven wheel 37, and the first motor 36 is started. The first motor 36 drives the driving wheel 35 to rotate. Since the driven wheel 37 is frictionally connected with the driving wheel 35, the driven wheel 37 rotates accordingly. The driving wheel 35 and the driven wheel 37 work together to pull the tape out of the tape storage wheel 31 and transport it along the guide groove of the tape guide frame 34 to the tape outlet of the tape outlet block 33, ensuring that the tape can accurately reach the position of the carton to be pasted at the corner.

[0034] As the sliding block 24 moves up and down driven by the electric cylinder 23, the tape outlet block 33 moves synchronously with the sliding block 24. When the pressing component 2 performs the pressing operation, the tape is promptly delivered to the pressing notch, so that the pressing block 25 can smoothly press the tape onto the carton. When one corner pasting operation is completed, the cutting knife 26 cuts off the tape, and the first motor 36 continues to operate to deliver the tape for the next corner pasting, thereby achieving stable conveying of the tape and cooperating with the pressing component 2 to complete the corner pasting work of the carton.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4, the adjustment assembly 6 includes a right-angle frame 61, a cross hinge 62, a first electric telescopic rod 63, a sliding block 64, a second electric telescopic rod 65, a gear 66, a rack 67, an airbag 68, and an adjustment telescopic rod 69. The right-angle frame 61 is L-shaped, and there are four right-angle frames 61. The four right-angle frames 61 are enclosed in a rectangle and are slidably arranged on the paper box tray 4. There are also four groups of cross hinges 62. The cross hinge 62 is installed between two adjacent right-angle frames 61. The cross hinge 62 is composed of two connecting rods hinged to each other in the middle. The two ends of the connecting rod are respectively hinged to two adjacent right-angle frames 61. The fixed end of the first electric telescopic rod 63 is fixedly installed on the paper box tray 4, and the output end of the first electric telescopic rod 63 is fixedly connected to the right-angle frame 61.

[0036] Referring to Figure 3 and Figure 4 , a sliding groove 41 is opened on the paper box tray 4, and an installation cavity 42 is opened on the paper box tray 4. The sliding groove 41 communicates with the installation cavity 42. The sliding block 64 is perpendicular to the paper box tray 4 and there are two sliding blocks 64. One end of a sliding block 64 is rotatably connected to the cross hinge 62, and the other end is slidably arranged in the sliding groove 41. The two sliding blocks 64 are symmetrically arranged, and both sliding blocks 64 are slidably arranged in the sliding groove 41. The fixed end of the second electric telescopic rod 65 is fixedly installed on the paper box tray 4, and the output end of the second electric telescopic rod 65 is fixedly connected to the sliding block 64. The second electric telescopic rod 65 is perpendicular to the axis of the first electric telescopic rod 63. The gear 66 is arranged in the installation cavity 42 and is located at the center of the paper tray box. The gear 66 is rotatably arranged on the paper box tray 4, and the axis of the gear 66 is perpendicular to the pushing direction of the second electric telescopic rod 65. The number of racks 67 is two. One end of the rack 67 is fixedly connected to the sliding block 64, and the rack 67 meshes with the gear 66.

[0037] Referring to Figure 2 and Figure 4 , the airbag 68 is fixedly arranged in the sliding groove 41 and abuts against the sliding block 64. The airbag 68 is located on the side away from the axis of the paper box tray 4. One end of the adjustment telescopic rod 69 is fixedly connected to the support frame 21, and the other end of the adjustment telescopic rod 69 is fixedly connected to the slide rail 22. The airbag 68 communicates with the rodless cavity of the adjustment telescopic rod 69 through a hose.

[0038] When using the carton corner pasting device, if it is necessary to adjust the paper box tray 4 to adapt to different specifications of cartons, the first electric telescopic rod 63 and the second electric telescopic rod 65 can be started according to the carton size requirements. When the first electric telescopic rod 63 expands and contracts, it pushes the connected right-angle frame 61 to slide on the paper box tray 4. Since the four right-angle frames 61 are interconnected through the cross hinge 62, the opposite two right-angle frames 61 move synchronously and in opposite directions, thereby adjusting the size of the rectangle formed in one direction.

[0039] Meanwhile, the second electric telescopic rod 65 drives the sliding block 64 to slide in the sliding groove 41. The sliding block 64 drives the rack 67 to move. Through the meshing transmission of the gear 66 and the rack 67, the two sliding blocks 64 achieve synchronous reverse movement, thereby adjusting the position of the right-angle frame 61 in the direction perpendicular to the first electric telescopic rod 63, completing two-dimensional size adjustment, and adapting to cartons of different lengths and widths.

[0040] During the sliding process of the sliding block 64, the airbag 68 is squeezed or separated. When the sliding block 64 squeezes the airbag 68, the gas in the airbag 68 enters the rod chamber of the adjustment telescopic rod 69 through the hose, prompting the adjustment telescopic rod 69 to act, driving the slide rail 22 to move along the height direction of the support frame 21, and adjusting the height of the pressing assembly 2; when the sliding block 64 moves away from the airbag 68, the airbag 68 restores its deformation, and the gas in the rod chamber flows back, and the adjustment telescopic rod 69 acts in the reverse direction to ensure that the pressing assembly 2 is at an appropriate height. Through the adjustment assembly 6, the size adjustment of the carton tray 4 and the height adaptation of the pressing assembly 2 are completed to meet the production requirements of cartons of different specifications.

[0041] Refer to Figure 1 , the driving member 5 includes a second motor 51 and a third electric telescopic rod 52. The driving member 5 is located on the side of the carton tray 4 away from the conveying assembly 3. The fixed end of the second motor 51 is fixedly installed on the frame 1. One end of the third electric telescopic rod 52 is coaxially and fixedly connected to the output end of the second motor 51, and the other end of the third electric telescopic rod 52 is coaxially and fixedly connected to the carton tray 4.

[0042] When using the carton corner pasting device, start the second motor 51, drive the third electric telescopic rod 52 to rotate, and at the same time drive the carton tray 4 to rotate, convey the carton to the designated position below the pressing assembly 2, so that the carton corner and the tape pasting area are accurately corresponding. When encountering cartons of different thicknesses, the distance between the carton tray 4 and the pressing assembly 2 can be adjusted axially by controlling the telescopic movement of the third electric telescopic rod 52 to ensure that the pressing assembly 2 can closely fit the carton surface for tape pressing. After one pressing is completed, the second motor 51 rotates 90 degrees, and then another pressing is performed until all four corners of the rectangular carton are completed with pressing.

[0043] Refer to Figure 4 , a pressing disk 7 is rotatably installed on the frame 1. The pressing disk 7 is arranged parallel to the carton tray 4. The pressing disk 7 is located on the side away from the driving member 5. A sponge block 71 is fixedly installed on the pressing disk 7.

[0044] During the corner pasting operation of the paper box, the paper box is placed on the paper box tray 4. The driving member 5 drives the paper box tray 4 to move, transporting the paper box to the lower part of the pressing and pasting assembly 2. At this time, the sponge block 71 on the pressing disk 7 is in close contact with the paper box. The sponge block 71 has good elasticity and can avoid damaging the surface of the paper box while applying pressure. The pressing disk 7 cooperates with the paper box tray 4 to firmly clamp the paper box from both left and right directions, preventing the paper box from shaking, shifting, etc. due to force during the tape pasting process, ensuring that the tape can be smoothly attached to the corners of the paper box, improving the corner pasting quality and accuracy, reducing the generation of defective products. After the corner pasting process is completed, the paper box tray 4 rotates and resets to facilitate the removal of the paper box with the corners pasted.

[0045] The implementation principle of an automatic adjustable paper box corner pasting device in an embodiment of this application is as follows: According to the specifications of the paper box, the first electric telescopic rod 63 and the second electric telescopic rod 65 in the adjustment assembly 6 are used to drive the right-angle frame 61 and the sliding block 64 respectively. Through the characteristics of the cross hinge 62 and the gear 66 and rack 67 transmission, two-dimensional precise adjustment of the size of the paper box tray 4 is achieved. At the same time, the sliding block 64 squeezes or releases the airbag 68, which is linked with the adjustment telescopic rod 69 through a hose to adaptively adjust the height of the pressing and pasting assembly 2 to complete the preparatory work before corner pasting.

[0046] Place the paper box from the previous processing step on the adjusted paper box tray 4. The second motor 51 drives the third electric telescopic rod 52, and then drives the paper box tray 4 to rotate, rotating the paper box to the specified position. At the same time, the third electric telescopic rod 52 can adjust the distance between the paper box tray 4 and the pressing and pasting assembly 2 according to the thickness of the paper box. At this time, the first motor 36 of the conveying assembly 3 drives the driving wheel 35, and through the friction transmission of the driven wheel 37, the tape is pulled from the tape storage wheel 31 and conveyed along the tape guide frame 34 to the tape outlet of the tape outlet block 33 to ensure the accurate positioning of the tape.

[0047] Start the pressing and pasting assembly 2. The electric cylinder 23 drives the sliding block 24 to move along the slide rail 22, driving the pressing block 25 and the cutting knife 26 to act synchronously. The pressing notch of the pressing block 25 fits the corners of the paper box, firmly pressing the tape on the paper box. Subsequently, the cutting knife 26 cooperates with the pressing block 25 to cut off the tape, completing one corner pasting operation. The sponge block 71 on the pressing disk 7 cooperates with the paper box tray 4 to firmly clamp the paper box, preventing it from shaking and shifting during corner pasting, and improving the efficiency and quality of paper box corner pasting.

[0048] The above are all preferred embodiments of this application. The protection scope of this application is not limited accordingly.
