Description

Technical Field

[0001] This utility model belongs to the field of sealing equipment technology, specifically, it relates to an adjustable speed sealing machine. Background Technology

[0002] A bag sealing machine is an adjustable sealing machine with the advantages of flexibility and easy disassembly. It is suitable for small and medium-sized factories, docks, and warehouses to seal the mouths of various sacks, canvas bags, and plastic bags filled with grains, sugar, sand, powders, etc. The machine shell is made of aluminum alloy casting with good mechanical properties, so it is convenient and lightweight to use and easy to adjust.

[0003] In practical applications, it is usually necessary to install a spool of yarn wound on the spool of the sealing machine. However, since the position of the hand-held sealing machine changes with the hand movements during use, the spool is prone to falling off the spool, which is not conducive to stabilizing the spool. The yarn falls off the spool and needs to be rewound onto the spool.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 4 As shown

[0024] An adjustable speed sealing machine includes a sealing machine body 1. A cable tray 5 is fixedly mounted on the bottom side of the sealing machine body 1, and a support rod 6 is fixedly mounted on the top of the cable tray 5. The support rod 6 is located below a limiting plate 10. A track 7 is fixedly mounted on the side of the sealing machine body 1, and a lifting bracket 8 is slidably mounted on the track 7. A mounting plate 9 is slidably mounted on one side of the lifting bracket 8. A limiting plate 10 is fixedly mounted on the bottom outer wall of the mounting plate 9. A connecting spring 11 is mounted on one side of the lifting bracket 8, and one end of the connecting spring 11 is connected to the outer wall of one side of the mounting plate 9. When a cable spool is added, the mounting plate 9 is pushed to move, and the mounting plate 9 drives the limiting plate 10 to move. After the limiting plate 10 moves to a certain position, the cable spool can be mounted on the support rod 6, so that the bottom of the cable spool is flush with the cable tray. 5. After the top contacts are in contact and the spool is installed, the mounting plate 9 is released. Under the action of the connecting spring 11, the mounting plate 9 drives the limiting plate 10 to return to the position directly above the support rod 6. A positioning groove 12 is provided on one side of the lifting bracket 8. A first mounting shell 13 and a second mounting shell 16 are fixedly installed on the track 7. The second mounting shell 16 is located directly below the first mounting shell 13. A first positioning block 14 is slidably provided on the inner wall of the first mounting shell 13. The first positioning block 14 is adapted to the positioning groove 12. A second positioning block 17 is slidably provided on the inner wall of the second mounting shell 16. The second positioning block 17 is adapted to the positioning groove 12. Both the first positioning block 14 and the second positioning block 17 are wedge-shaped structures and are symmetrically arranged.

[0025] In a specific embodiment, a first compression spring 15 is installed on the inner wall of one side of the first mounting housing 13. One end of the first compression spring 15 is connected to the outer wall of one side of the first positioning block 14. A first opening is provided on one side of the first mounting housing 13, and a first connecting block 19 is slidably disposed on the inner wall of the first opening. The first connecting block 19 is fixedly connected to the outer wall of one side of the first positioning block 14. A second compression spring 18 is installed on the inner wall of one side of the second mounting housing 16. One end of the second compression spring 18 is connected to the outer wall of one side of the second positioning block 17. A second opening is provided on one side of the second mounting housing 16, and a second connecting block 20 is slidably disposed on the inner wall of the second opening. The second connecting block 20 is fixedly connected to the outer wall of one side of the second positioning block 17. When the spool is installed and the limiting plate 10 is located on the support rod 6... After reaching the top, pull the first connecting block 19 to move it. The first connecting block 19 drives the first positioning block 14 to move, causing the first positioning block 14 to disengage from the positioning groove 12. Then, move the lifting bracket 8 down. The lifting bracket 8 drives the limiting plate 10 to move downward. When the lifting bracket 8 moves down to contact the second positioning block 17, it squeezes the second positioning block 17 into the second mounting housing 16 until the limiting plate 10 contacts the top opening of the spool. At the same time, the positioning groove 12 moves to one side of the second positioning block 17. At this time, under the action of the second compression spring 18, the second positioning block 17 can be pushed into the positioning groove 12, realizing the positioning function of the lifting bracket 8. This makes the limiting plate 10 stabilize the spool and prevent the spool from falling off during the sealing process.

[0026] Furthermore, a handle 2 is installed at the bottom of the sealing machine body 1. The handle 2 is equipped with a switch button 3 and a speed adjustment knob 4. After the bobbin is stabilized, the yarn wound on the bobbin is threaded onto the sealing machine body 1. After threading is completed, the sealing machine body 1 is turned on by the switch button 3 to start the sealing work. During the sealing process, the operator can adjust the sealing speed at any time by using the speed adjustment knob 4 to adapt to different production needs.

[0027] The implementation principle of an adjustable speed sealing machine in this embodiment is as follows: In specific use, the mounting plate 9 is pushed to move, and the mounting plate 9 drives the limiting plate 10 to move. After the limiting plate 10 moves to a certain position, the bobbin is installed on the support rod 6 so that the bottom of the bobbin contacts the top of the cable tray 5. After the bobbin is installed, the mounting plate 9 is released. Under the action of the connecting spring 11, the mounting plate 9 drives the limiting plate 10 to return to the top of the support rod 6. Then, the first connecting block 19 is pulled to move, and the first connecting block 19 drives the first positioning block 14 to move, so that the first positioning block 14 disengages from the positioning groove 12. Then, the lifting bracket 8 is moved down, and the lifting bracket 8 drives the limiting plate 10 to move downward. When the lifting bracket 8 moves down to contact the second positioning block 17, the first positioning block 10 is moved down. The second positioning block 17 is pressed into the second mounting housing 16 until the limiting plate 10 contacts the top opening of the bobbin. At the same time, the positioning groove 12 moves to one side of the second positioning block 17. At this time, under the action of the second compression spring 18, the second positioning block 17 can be pushed into the positioning groove 12 to achieve the positioning function of the lifting bracket 8. Thus, the limiting plate 10 is positioned, which makes the limiting plate 10 stabilize the bobbin and prevent the bobbin from falling off during sealing. Then, the yarn wound on the bobbin is threaded onto the sealing machine body 1. After the threading is completed, the sealing machine body 1 is turned on by the switch button 3 to start the sealing work. During the sealing process, the operator can adjust the sealing speed at any time by using the speed adjustment knob 4 to adapt to different production needs.
