A semi-automatic corner cutting machine

Abstract

This utility model relates to the field of packaging and sealing technology, and in particular to a semi-automatic corner sealing machine, comprising a machine body, two lower conveying components installed on the upper part of the machine body, and an adjusting component for adjusting the distance between the two lower conveying components. Upper conveying components are installed on the upper end of the machine body via a lifting component. In this utility model, a moving conical block presses against a wedge block, thereby pushing a T-shaped rubber block to move, thus fixing the tape. A locking component can lock the position of the conical block to prevent the tape from falling off or loosening during the sealing process. Furthermore, in this utility model, the spring force pushes an L-shaped locking rod to engage with the locking teeth, thus locking the conical block. When the position of the conical block needs to be adjusted, the L-shaped locking rod is disengaged from the locking teeth. After adjustment, the L-shaped locking rod is released, allowing it to re-engage with the locking teeth under the spring force, thereby locking the new position of the conical block.

Description

Technical Field

[0001] This utility model relates to the field of packaging and sealing technology, and in particular to a semi-automatic corner sealing machine. Background Technology

[0002] After the product is fully assembled, it needs to be packaged in a cardboard box for easy storage and transportation in subsequent processes.

[0003] After the product is placed in the packaging box, the box opening only needs to be sealed. For example, Chinese Patent Announcement No. "CN221520229U" discloses an adaptive corner sealing machine. The upper part of the edge sealing machine body is equipped with an edge sealing component, and a leveling component is installed on the upper part of the edge sealing machine body corresponding to the position of the edge sealing component. The edge sealing component includes a transmission roller installed on the upper part of the edge sealing machine body. A lower adjustment frame is mounted on the upper part of the edge sealing machine body. Two connecting frames are symmetrically installed on the inner side of the lower adjustment frame, and one of the connecting frames is slidably connected to the lower adjustment frame.

[0004] Most existing corner edge wrapping machines install the tape on the unwinding roller. However, due to the different diameters of the inner cylinders of different tapes, it is not possible to fix the tape well. This may lead to uneven tape adhesion during the packaging process, or even breakage or slippage, thus affecting the overall packaging effect. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the inability to properly fix tape in the existing technology, and to propose a semi-automatic corner edge fixing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a semi-automatic edge sealing machine, including a machine body, two lower conveying components are installed on the top of the machine body, and an adjusting component is provided on the machine body for adjusting the distance between the two lower conveying components. An upper conveying component is installed on the upper end of the machine body through a lifting component, and edge sealing components are provided on both sides of the lower and upper conveying components.

[0008] An unwinding roller for mounting tape is provided on the edge sealing assembly. The unwinding roller is rotatably connected to a bracket on the edge sealing assembly via a connector. A tensioning mechanism is provided inside the unwinding roller.

[0009] Furthermore, the adjusting assembly includes a double-headed forward and reverse screw, which is rotatably connected to the machine body. The double-headed forward and reverse screw is threadedly connected to the connecting rods at the lower ends of the two lower conveying assemblies. Two slide rods are installed on the machine body and are slidably connected to the two lower conveying assemblies. Two connecting rods are fixedly connected to one side of the two lower conveying assemblies and are slidably connected to the upper conveying assembly.

[0010] Furthermore, the lifting assembly includes a fixed frame, which is slidably connected to the machine body. The lower end of the fixed frame is slidably connected to the upper conveying assembly. A screw is rotatably connected to the machine body, and the screw is threadedly connected to the fixed frame.

[0011] Furthermore, the connector includes a rotating shaft that passes through and is rotatably connected to the bracket. One end of the rotating shaft is fixedly connected to the unwinding roller. A limiting plate is fixedly connected to the surface of the rotating shaft, and the limiting plate abuts against the bracket. Positioning glass beads are embedded in the surface of the end of the rotating shaft. A baffle is also fitted on the rotating shaft, and positioning glass beads and the bracket abut on both sides of the baffle.

[0012] Furthermore, the tensioning mechanism includes a T-slot formed on the unwinding roller, with at least three T-slots. A T-shaped rubber block is slidably connected to the T-slot, and a wedge block is fixedly connected to the lower end of the T-shaped rubber block. A fixing rod is fixedly connected inside the unwinding roller, and a conical block is slidably connected to the fixing rod. The conical block abuts against the wedge block, and a locking element for locking the conical block is provided on the conical block.

[0013] Furthermore, the locking component includes several locking teeth formed on the surface of the fixing rod. An L-shaped groove is formed in the conical block, and an L-shaped locking rod is slidably connected in the L-shaped groove. The L-shaped locking rod and the locking teeth engage with each other. One end of the L-shaped locking rod is set as an inclined surface. A spring is fixedly connected to the upper end of the L-shaped locking rod, and one end of the spring is fixedly connected to the inner wall of the L-shaped groove.

[0014] The semi-automatic edge sealing machine proposed in this utility model has the following advantages: In this utility model, the moving conical block squeezes the wedge block, thereby pushing the T-shaped rubber block to move, thereby fixing the tape. The locking component can lock the position of the conical block to prevent the tape from falling off or loosening during the edge sealing process.

[0015] Secondly, in this invention, the L-shaped locking rod is pushed by the spring force to engage with the locking teeth, thereby locking the conical block. When the position of the conical block needs to be adjusted, the L-shaped locking rod is disengaged from the locking teeth, the position is adjusted, and then the L-shaped locking rod is released, so that it re-engages with the locking teeth under the action of the spring force, thereby locking the new position of the conical block.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-7 A semi-automatic edge sealing machine includes a body 1. Two lower conveying components 11 are installed on the top of the body 1. An adjusting component 2 is provided on the body 1 to adjust the distance between the two lower conveying components 11. An upper conveying component 12 is installed on the upper end of the body 1 via a lifting component 3. Edge sealing components 13 are provided on both sides of the lower conveying components 11 and the upper conveying components 12. In this invention, the adjusting component 2 and the lifting component 3 can be adjusted according to the size of the packaging box so that the lower conveying components 11 and the upper conveying components 12 can fit snugly against the packaging box, preventing the packaging box from shifting during transport and causing abnormal edge sealing.

[0026] An unwinding roller 14 for installing tape is provided on the edge sealing assembly 13. The unwinding roller 14 is rotatably connected to the bracket 15 on the edge sealing assembly 13 via a connector 4. A tensioning mechanism 5 is provided inside the unwinding roller 14. In this utility model, the unwinding roller 14 can be quickly disassembled and installed via the connector 4, which facilitates the replacement and maintenance of the unwinding roller 14. The tensioning mechanism 5 is used to tighten the inner ring of the tape to prevent the tape from falling off during edge sealing.

[0027] Furthermore, the adjustment component 2 includes a double-headed positive and negative screw 21, which is rotatably connected to the machine body 1. In this embodiment, the double-headed positive and negative screw 21 can be driven by a motor. The double-headed positive and negative screw 21 is threadedly connected to the connecting rods at the lower ends of the two lower conveying components 11 respectively. Two sliding rods 22 are installed on the machine body 1, and the sliding rods 22 are slidably connected to the two lower conveying components 11. Two connecting rods 23 are fixedly connected to one side of the two lower conveying components 11, and the connecting rods 23 are slidably connected to the upper conveying component 12. In this utility model, the distance between the two lower conveying components 11 is adjusted by rotating the double-headed positive and negative screw 21. The connecting rods 23 ensure the relative positional relationship between the upper conveying component 12 and the lower conveying component 11, so that while adjusting the distance between the lower conveying components 11, the upper conveying component 12 can also adjust its position accordingly to maintain its fit with the packaging box.

[0028] Furthermore, the lifting assembly 3 includes a fixed frame 31, which is slidably connected to the body 1. The lower end of the fixed frame 31 is slidably connected to the upper conveying assembly 12. A screw 32 is rotatably connected to the body 1. In this embodiment, the screw 32 is driven by a motor and is threadedly connected to the fixed frame 31. In this utility model, by rotating the screw 32, the fixed frame 31 is driven to slide up and down along the guide structure of the body 1, thereby driving the upper conveying assembly 12 to rise or fall to adapt to packaging boxes of different heights.

[0029] The connecting component 4 includes a rotating shaft 41, which passes through and is rotatably connected to the bracket 15. One end of the rotating shaft 41 is fixedly connected to the unwinding roller 14. A limiting plate 42 is fixedly connected to the surface of the rotating shaft 41, and the limiting plate 42 abuts against the bracket 15. A positioning glass bead 43 is embedded in the surface of the end of the rotating shaft 41. A baffle 44 is also sleeved on the rotating shaft 41. The positioning glass beads 43 on both sides of the baffle 44 abut against the bracket 15. In this utility model, when it is necessary to replace or repair the unwinding roller 14, the unwinding roller 14 can be removed from the bracket 15 by pressing the positioning glass bead 43, which is convenient for replacement and repair.

[0030] In addition, the tensioning mechanism 5 includes a T-slot 51 formed on the unwinding roller 14. There are at least three T-slots 51. A T-shaped rubber block 52 is slidably connected to the T-slot 51. A wedge block 53 is fixedly connected to the lower end of the T-shaped rubber block 52. A fixing rod 54 is fixedly connected inside the unwinding roller 14. A conical block 55 is slidably connected to the fixing rod 54. The conical block 55 abuts against the wedge block 53. A locking member 56 for locking the conical block 55 is provided on the conical block 55. In this invention, by moving the conical block 55 to squeeze the wedge block 53, the T-shaped rubber block 52 is pushed to move, thereby fixing the tape. The position of the conical block 55 can be locked by the locking member 56 to prevent the tape from falling off or loosening during the sealing process.

[0031] Furthermore, the locking component 56 includes locking teeth 561 formed on the surface of the fixing rod 54. Several locking teeth 561 are connected to an L-shaped groove 562 formed within the conical block 55. An L-shaped locking rod 563 is slidably connected within the L-shaped groove 562, and the L-shaped locking rod 563 engages with the locking teeth 561. One end of the L-shaped locking rod 563 is beveled, and a spring 564 is fixedly connected to the upper end of the L-shaped locking rod 563. One end of the spring 564 is connected to the L-shaped groove 562. The inner wall is fixedly connected. In this utility model, the spring force of the spring 564 pushes the L-shaped locking rod 563 to engage with the locking tooth 561, which can lock the conical block 55. When it is necessary to adjust the position of the conical block 55, the L-shaped locking rod 563 is disengaged from the locking tooth 561. After the position is adjusted, the L-shaped locking rod 563 is released again, so that it re-engages with the locking tooth 561 under the action of the spring force of the spring 564, thereby locking the new position of the conical block 55.

[0032] Operating mode: During operation, the distance between the two lower conveyor components 11 is adjusted by rotating the double-headed forward and reverse screws 21. The connecting rod 23 ensures the relative position of the upper conveyor component 12 and the lower conveyor component 11, so that while adjusting the distance between the lower conveyor components 11, the upper conveyor component 12 can also adjust its position accordingly to maintain a close fit with the packaging box. By rotating the screw 32, the fixing frame 31 is driven to slide up and down along the guide structure of the machine body 1, thereby raising or lowering the upper conveyor component 12 to accommodate packaging boxes of different heights. When it is necessary to replace or repair the unwinding roller 14, the positioning glass bead 43 is pressed. The unwinding roller 14 can be detached from the bracket 15 for easy replacement and maintenance. By moving the conical block 55 to squeeze the wedge block 53, the T-shaped rubber block 52 is moved, thereby fixing the tape. The spring force of the spring 564 pushes the L-shaped locking rod 563 to engage with the locking tooth 561, which can lock the conical block 55. When the position of the conical block 55 needs to be adjusted, the L-shaped locking rod 563 is disengaged from the locking tooth 561. After the position is adjusted, the L-shaped locking rod 563 is released, so that it re-engages with the locking tooth 561 under the action of the spring force of the spring 564, thereby locking the new position of the conical block 55.
