Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and specifically to a packaging machine. Background Technology

[0002] Packing machines, also known as strapping machines or bundling machines, are portable and highly efficient. They are easy to carry and are widely used in various industries for packing and bundling goods of all sizes. When packing goods, the goods are usually placed in a packing box, and the packing box is tied with packing straps. The packing machine tightens the packing straps and cuts off the excess, then welds the cut ends together.

[0003] When cutting strapping of different thicknesses, the welding components of the strapping machine need to be adjusted. Usually, this involves replacing the elastic element that is sleeved on the outside of the support shaft, or directly turning the support shaft to adjust the compression of the elastic element. However, when turning the support shaft, the locking nut is easily rotated synchronously, making it difficult to adjust the elastic element. It is necessary to fix the locking nut before turning the support shaft. Utility Model Content

[0024] To make the objectives and technical solutions of the present utility model embodiments clearer, the following will be described in conjunction with the accompanying drawings of the present utility model embodiments. Figure 1 -Appendix Figure 5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] like Figure 1 As shown, a strapping machine 1 is used to tighten and friction-weld the strapping to package items. The strapping machine 1 includes a mounting base 11 and a mounting block 12, with the mounting block 12 fixedly mounted on the mounting base 11.

[0026] like Figure 1As shown, the packing machine 1 includes a welding assembly 13, an operating assembly 14, and a driving assembly 15. The welding assembly 13 is mounted on the mounting base 11 and abuts against the operating assembly 14. The operating assembly 14 is rotatably mounted on the mounting block 12. The driving assembly 15 is mounted on the mounting base 11 and connected to the welding assembly 13. The driving assembly 15 drives the welding assembly 13 to work, and the operating assembly 14 rotates to cause the welding assembly 13 to press the packing strap.

[0027] like Figure 1 As shown, the welding assembly 13 includes a clamping unit 131, an upper welding tooth 132, a lower welding tooth 133, and a cutting unit 134. The clamping unit 131 is rotatably connected to the mounting block 12. The lower end of the clamping unit 131 abuts against the upper welding tooth 132. The upper welding tooth 132 is connected to the driving assembly 15. The lower welding tooth 133 is located below the upper welding tooth 132. The cutting unit 134 is connected to the upper welding tooth 132.

[0028] like Figure 2 As shown, the clamping unit 131 includes a clamping seat 1311, a support shaft 1312, an elastic element 1313, and a locking nut 1314. One end of the clamping seat 1311 is rotatably connected to the mounting block 12, and the clamping seat 1311 has two protruding steps, one above the other. The elastic element 1313 is fitted onto the outer side of the support shaft 1312, and the support shaft 1312 passes through the clamping seat 1311. The cap end of the support shaft 1312 faces the welding upper tooth 132. One end of the elastic element 1313 abuts against the cap end of the support shaft 1312, and the other end abuts against the upper step of the clamping seat 1311. The elastic element 1313 is in a compressed state. The locking nut 1314 is screwed onto the threaded end of the support shaft 1312, fixing the support shaft 1312 onto the clamping seat 1311.

[0029] like Figure 2 As shown, the clamping unit 131 further includes a limiting block 1315, which is disposed at the upper end of the clamping seat 1311. The limiting block 1315 abuts against the locking nut 1314 and is used to restrict the rotation of the locking nut 1314 to prevent the locking nut 1314 from rotating when the support shaft 1312 is turned to adjust the compression of the elastic element 1313.

[0030] like Figure 2 As shown, the clamping unit 131 also includes a pin 1316 and a roller 1317. The pin 1316 is disposed on the clamping seat 1311, and the roller 1317 is fitted on the pin 1316. The operating component 14 abuts against the roller 1317.

[0031] Specifically, the operating component 14 abuts against the pressing unit 131. When the operator presses the operating component 14, the operating component 14 applies pressure to the pressing unit 131, causing the pressing unit 131 to rotate downwards. This causes the welding upper teeth 132 to move downwards until the welding upper teeth 132 press against the packing strap. The cutting unit 134 moves downwards together with the welding upper teeth 132. The cutting unit 134 remains in close contact with the upper packing strap. The driving component 15 drives the welding upper teeth 132 to perform friction welding on the packing strap. The cutting unit 134 and the upper packing strap generate a relative horizontal reciprocating motion, cutting the packing strap.

[0032] like Figure 1 As shown, the operating component 14 includes a rotating shaft 141, a button 142, a pressure plate 143, and a micro switch 144. The rotating shaft 141 is mounted through the mounting block 12. The pressure plate 143 is fixedly connected to the button 142 and is fitted onto the rotating shaft 141. The button 142 and the pressure plate 143 rotate synchronously. The micro switch 144 is mounted on the mounting block 12. The rotation of the pressure plate 143 triggers the micro switch 144.

[0033] Specifically, such as Figure 2 As shown, the pressure plate 143 abuts against the roller 1317. The button 142 and the pressure plate 143 rotate synchronously. The pressure plate 143 applies pressure to the roller 1317, which further drives the pressing unit 131 to move downward. The pressing unit 131 drives the welding upper teeth 132 to move downward until they are pressed against the packing strap. At the same time, the rotation of the pressure plate 143 triggers the micro switch 144. The signal of the micro switch 144 changes, and the driving component 15 drives the welding upper teeth 132 to perform friction welding.

[0034] like Figure 1 As shown, the packing machine 1 also includes a handle 16, a transmission assembly 17, and a tensioning assembly 18. The handle 16 is fixedly connected to the transmission assembly 17. The transmission assembly 17 passes through the mounting block 12 and is connected to the tensioning assembly 18. The rotation of the handle 16 drives the transmission assembly 17 to lift or lower, which in turn drives the tensioning assembly 18 to lift or lower.

[0035] like Figure 3 As shown, the transmission assembly 17 includes a drive component 171, a reduction gearbox 172, a worm gear mechanism 173, and a mounting box 174. The output end of the drive component 171 is connected to the reduction gearbox 172, as shown. Figure 3As shown, the worm gear mechanism 173 is installed in the mounting box 174, which is connected to the reduction gearbox 172. One end of the worm gear mechanism 173 is connected to the reduction gearbox 172, and the other end is connected to the tensioning assembly 18. The drive component 171 drives the tensioning assembly 18 to tighten or loosen the packing strap via the reduction gearbox 172 and the worm gear mechanism 173. The handle 16 is fixedly connected to the mounting box 174, and rotating the handle 16 causes the mounting box 174 to rotate.

[0036] like Figure 2 As shown, the tensioning assembly 18 includes a hinge shaft 181, an end cap 182, a tensioning wheel 183, and a toothed plate 184. One end of the hinge shaft 181 passes through the mounting block 12 and is connected to the mounting box 174. The other end of the hinge shaft 181 is connected to the end cap 182. The tensioning wheel 183 is connected to the worm gear mechanism 173. The toothed plate 184 is disposed below the tensioning wheel 183.

[0037] Specifically, the end cap 182 covers the outside of the tensioning wheel 183.

[0038] When the handle 16 is lifted, the mounting box 174 is lifted, and the mounting box 174 lifts the end cover 182 via the hinge shaft 181. The worm gear mechanism 173 is installed inside the mounting box 174 and lifts along with the mounting box 174, further lifting the tension wheel 183 and placing the packing strap between the tension wheel 183 and the toothed plate 184. When the handle 16 is pressed down, the tension wheel 183 falls, and the drive member 171 drives the tension wheel 183 to rotate and tighten the packing strap. After packing is completed, the handle 16 is lifted, and the drive member 171 drives the tension wheel 183 to rotate in the opposite direction to remove the packing strap and lift it up.

[0039] like Figure 4 As shown, the packing machine 1 also includes a housing 19, which protects the internal structure of the packing machine 1. The housing 19 has an opening 191 and a plug 192. The opening 191 is located above the support shaft 1312, and the plug 192 is inserted into the opening 191. When the plug 192 is pulled out, a screwdriver is inserted into the opening 191, and the support shaft 1312 is turned. The limiting block 1315 abuts against the locking nut 1314, preventing the locking nut 1314 from rotating with the support shaft 1312, thereby adjusting the compression length of the elastic element 1313. This is used to adjust the clamping force of the clamping unit 131 to adapt to packing straps of different thicknesses.

[0040] like Figure 4As shown, in order to facilitate cleaning and maintenance of the tensioning wheel 183, the end cap 182 and the tensioning wheel 183 are exposed outside the housing 19. After removing the end cap 182, the tensioning wheel 183 is exposed, which facilitates cleaning the packing tape debris on the tensioning wheel 183 and the toothed plate 184, as well as maintenance or replacement of the tensioning wheel 183 and the toothed plate 184.

[0041] like Figure 4 As shown, the upper welding tooth 132 and the cutting unit 134 are exposed on the outside of the housing 19, which facilitates the cleaning of the packing tape debris adhering to the upper welding tooth 132, the lower welding tooth 133 and the cutting unit 134, as well as the maintenance of the upper welding tooth 132, the lower welding tooth 133 and the cutting unit 134, especially the replacement of the worn blade of the cutting unit 134. The spring of the cutting unit 134 can also be replaced or adjusted to make it suitable for packing tape of different thicknesses.

[0042] like Figure 5 As shown, in order to check the working status of the drive unit 171 and the drive assembly 15 at any time, the housing 19 may also include a removable access port 193. The access port 193 is located on the side of the housing 19 where the drive assembly 15 is located. The access port 193 is aligned with the output end of the drive unit 171 and the drive assembly 15. The access port 193 is used to inspect the drive unit 171 and the drive assembly 15.

[0043] It should be noted that the structure of the packing machine 1 in this utility model is only a specific embodiment provided for ease of description, and the housing 19 can be applied to packing machines 1 with other internal structures.

[0044] This utility model provides a baling machine that facilitates adjustment of clamping force and maintenance. A limit block is installed on the clamping seat to restrict the rotation of the locking nut, preventing it from rotating when the support shaft is turned to adjust the compression of the elastic element. An opening is provided in the housing above the support shaft, allowing a screwdriver to be inserted to tighten the shaft. The tensioning wheel and end cap of the tensioning assembly, as well as the welding teeth and cutting unit of the welding assembly, are exposed outside the housing for easy cleaning, maintenance, and adjustment. An inspection port is provided on the other side of the housing for easy maintenance of the drive assembly and drive components. This utility model's baling machine has a simple housing structure, facilitates maintenance and adjustment of clamping force, and is suitable for the internal structures of baling machines with different configurations.
