Description

Technical Field

[0001] This utility model relates to the field of carton sealing machine technology, and in particular to a safe automatic carton folding and sealing machine. Background Technology

[0002] An automatic carton folding and sealing machine is a mechanical device that can automatically complete the tasks of folding and sealing cartons. Depending on the degree of automation, automatic carton folding and sealing machines can be divided into semi-automatic and fully automatic carton folding and sealing machines. Fully automatic carton folding and sealing machines have a higher degree of automation and efficiency and can completely replace manual labor in completing the sealing work.

[0003] A multi-set automatic carton folding and sealing machine (CN218929899U) can be referenced in existing literature. The reference uses at least two sets of outward-pushing mechanisms on one side of the folding mechanism to pre-process the carton to be folded and packaged. This causes the long lid of the carton that does not conform to the folding and sealing process of the sealing machine to be pushed outward. This allows the folding mechanism to fold the short lid first, and then the folding rod to fold the long lid. After that, the sealing operation is performed by the flat pressure block. This utility model eliminates the need for manual adjustment of the inward and outward orientation of some short and long lids, thus improving the sealing efficiency.

[0004] As shown in the aforementioned literature, traditional automatic carton sealing machines often use two transmission mechanisms to transport the carton placed on the worktable. The transmission mechanisms are fixedly installed on the worktable, so the distance between the two transmission mechanisms is also fixed. When the width of the carton and the distance do not match, it is difficult to effectively transmit the carton. In the existing technology, some higher-end products are equipped with a distance adjustment mechanism, but this mechanism is generally adjusted by turning a handwheel. The adjustment accuracy of manual operation is difficult to control, and excessive contact pressure during adjustment can easily damage the carton, so the safety of use needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a safe and automatic carton folding and sealing machine. This invention utilizes an adjusting component to drive two bidirectional lead screws to rotate, which in turn causes two externally threaded adjusting seats to move in opposite directions. This allows the transmission mechanism above the adjusting seats to effectively transport the carton. Adjustments are made according to the width of the carton, and a pressure sensor detects the contact pressure during adjustment, effectively preventing damage to the carton due to excessive contact pressure.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An automatic carton sealing and folding machine includes: a worktable, with two bidirectional lead screws rotatably connected to both ends of the worktable; an adjustment assembly is provided at the front of the worktable; two auxiliary transmission cylinders in the adjustment assembly are respectively fixed to one end of the two bidirectional lead screws; two adjustment seats are threadedly connected to the outside of the bidirectional lead screws; a transmission mechanism is fixedly installed above each adjustment seat; a pressure sensor is connected above the transmission mechanism; and a pressure display panel is connected above the pressure sensor.

[0008] The present invention is further configured to include an adjustment component comprising: a servo motor, which is fixedly installed in a mounting slot in front of the worktable, the output end of the servo motor being connected to a main transmission cylinder, and two transmission slots being formed on the surface of the main transmission cylinder.

[0009] The present invention is further configured such that the adjustment component also includes: a belt, which has two belts and is sleeved on the outside of the transmission grooves on the surface of the main transmission cylinder, the two auxiliary transmission cylinders having transmission grooves of the same size on their surfaces, and the other end of the belt is sleeved on the outside of the transmission grooves on the surface of the auxiliary transmission cylinders.

[0010] The present invention is further configured such that a plurality of movable rollers are rotatably connected inside the worktable, and a number of sleeve holes corresponding to the movable rollers are opened on the surface of the adjusting seat, and all movable rollers pass through the sleeve holes.

[0011] The present invention is further configured such that a PLC controller is connected to the left side of the workbench, the PLC controller is electrically connected to the servo motor, and the PLC controller is connected to the pressure sensor signal.

[0012] The present invention is further configured such that the upper end of the workbench is welded with support columns on both the front and rear sides, and a crossbar is connected above the two support columns. An electric cylinder is fixedly installed in the middle of the upper end of the crossbar. The telescopic end of the electric cylinder is connected to a mounting seat, and the mounting seat is slidably connected to the front and rear support columns.

[0013] The present invention is further provided with a folding cover mechanism on the left side of the mounting base and a sealing mechanism on the upper right side of the mounting base.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. During the commissioning phase, the automatic box-sealing machine can rotate two bidirectional lead screws inside the worktable by adjusting the components in front of the worktable. Then, the box can be placed on the top of the worktable. The two adjusting seats outside the bidirectional lead screws move towards the center, and the transmission mechanism above the adjusting seats contacts the box and drives the box to be transported. This design allows for corresponding adjustments based on the width of the box during the commissioning phase, resulting in higher efficiency and accuracy in automated operation.

[0016] 2. During the commissioning of this automatic carton folding and sealing machine, when the two transmission mechanisms come into contact with both ends of the carton, the pressure sensors above the transmission mechanisms simultaneously come into contact with both ends of the carton. The real-time pressure is displayed on the pressure display panel and transmitted to the PLC controller. The PLC controller can preset the pressure value. When the contact pressure reaches the preset value, the two adjusting seats stop moving, ensuring that the contact pressure can just drive the carton to be conveyed without damaging the carton, thus improving the safety of use.

[0026] Reference Figure 1-4 An automatic carton sealing and folding machine includes: a workbench 1, on which a carton is placed and transported by two symmetrically designed transmission mechanisms 12. A gantry structure is provided above the workbench 1. The gantry structure includes two support columns 5 and a crossbar 6. The two support columns 5 are welded to the upper end of the workbench 1, and the crossbar 6 is welded above the two support columns 5. An electric cylinder 7 is fixedly installed at the upper end of the crossbar 6. The telescopic end of the electric cylinder 7 passes through the crossbar 6 and is connected to the mounting base 8, thereby driving the mounting base 8 to adjust its longitudinal height.

[0027] Specifically, mounting base 8 is used to install folding mechanism 9 and sealing mechanism 10. Folding mechanism 9 and sealing mechanism 10 have the same structure as existing automatic folding and sealing machines. The box first passes through folding mechanism 9 to fold and close the long and short lids, and then passes through sealing mechanism 10 to connect tape for sealing. The automated operation is centrally controlled and parameter set by PLC controller 4 on the left side of workbench 1.

[0028] like Figure 1 As shown, bidirectional lead screws 18 are rotatably connected to both ends inside the worktable 1, and multiple movable rollers 13 are rotatably connected and arranged at equal intervals inside the worktable 1.

[0029] Specifically, such as Figure 3 As shown, two adjusting seats 11 are threaded to the outside of the two bidirectional lead screws 18. The surfaces of the two adjusting seats 11 are provided with sleeve holes 19 corresponding to the number of movable rollers 13, and the movable rollers 13 pass through the sleeve holes 19.

[0030] Specifically, such as Figure 1 As shown, an adjustment component is provided in front of the worktable 1, and can also be referenced. Figure 2The adjustment assembly consists of a main drive cylinder 3, a servo motor 14, a belt 16, and an auxiliary drive cylinder 17.

[0031] Furthermore, a square mounting slot 2 is provided in the center of the front of the workbench 1 for fixing the servo motor 14. The output end of the servo motor 14 is connected to the main transmission cylinder 3. Two annular transmission slots 15 are provided on the surface of the main transmission cylinder 3. At the same time, an identical transmission slot 15 is provided on the surface of each of the two auxiliary transmission cylinders 17.

[0032] Furthermore, the belts 16 are all sleeved on the outside of the transmission grooves 15 of the main transmission cylinder 3 and the auxiliary transmission cylinder 17, and both auxiliary transmission cylinders 17 pass through the worktable 1 and are fixed to one end of the double-acting lead screw 18.

[0033] In this embodiment, the main drive cylinder 3 is driven to rotate by the operation of the servo motor 14. The main drive cylinder 3 drives the two auxiliary drive cylinders 17 to rotate synchronously through two belts 16, thereby causing the two bidirectional lead screws 18 to rotate synchronously. This allows the two adjusting seats 11 connected to the external threads of the bidirectional lead screws 18 to move in opposite directions along the bidirectional lead screws 18.

[0034] Specifically, the transmission mechanisms 12 are all fixedly installed above the adjusting seats 11, and the two transmission mechanisms 12 are driven to move in opposite directions by the reverse movement of the two adjusting seats 11.

[0035] In this embodiment, during the debugging process, the distance between the two transmission mechanisms 12 can be adjusted according to the width of the box, so that the two transmission mechanisms 12 can effectively drive the box to be transported.

[0036] Specifically, such as Figure 4 As shown, pressure sensors 20 are installed above both transmission mechanisms 12 in this device, and a pressure display panel 21 is provided above the pressure sensors 20.

[0037] Therefore, as Figure 1 As shown, when the two transmission mechanisms 12 come into contact with both ends of the housing, both ends of the housing simultaneously come into contact with the pressure sensor 20, thereby detecting the contact pressure, and the detection data is displayed through the pressure display panel 21.

[0038] Furthermore, the pressure sensor 20 is also connected to the PLC controller 4. The pressure value can be preset by the PLC controller 4. The pressure sensor 20 will transmit the real-time monitoring signal to the PLC controller 4 for value comparison. When the preset value is reached, the PLC controller 4 will automatically shut down the operation of the servo motor 14 in the adjustment component, thereby preventing the two transmission mechanisms 12 from moving. This ensures that the two transmission mechanisms 12 can just drive the box to transport without damaging the box.

[0039] Working Principle: When using this invention, during the debugging phase, the adjustment component in front of the workbench 1 can drive the two bidirectional lead screws 18 inside the workbench 1 to rotate. Then, the box can be placed on top of the workbench 1. The two adjustment seats 11 outside the bidirectional lead screws 18 move towards the center. The transmission mechanism 12 above the adjustment seats 11 contacts the box and drives the box to be transported. This design allows for corresponding adjustments according to the width of the box during the debugging phase, resulting in higher efficiency and accuracy in automated operation. During the debugging process, when the two transmission mechanisms 12 contact both ends of the box, the pressure sensors 20 above the transmission mechanisms 12 simultaneously contact both ends of the box. The real-time pressure is displayed through the pressure display panel 21 and transmitted to the PLC controller 4. The PLC controller 4 can preset the pressure value. When the contact pressure reaches the preset value, the two adjustment seats 11 stop moving, ensuring that the contact pressure can just drive the box to be transported without damaging the box, thus improving safety.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
