[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Example 1

[0040] This embodiment provides a packaging device, such as the attached Figure 1-4 As shown, including:

[0041] The friction assembly includes a bottom mold 12 fixed to the machine body 11 and a lower tooth plate 14 fixed to the plate tooth seat 13. Here, the machine body 11 includes a machine base 23, and the bottom mold 12 is fixed to the machine base 23. The lower tooth plate 14 is connected and fixed to the plate tooth seat 13. Here, the lower tooth plate 14 and the plate tooth seat 13 can be a detachable structure, that is, the two are connected by bolts or snap-on connection. Alternatively, the lower tooth plate 14 and the plate tooth seat 13 are integrally formed.

[0042] The driving mechanism includes a connecting rod seat 15 and a first driving source 21. The connecting rod seat 15 is movably connected to the plate gear seat 13. The movably connected connection can be a rotating connection, a bearing fit, or other movably connected modes. When the connecting rod seat 15 moves, the connecting rod seat 15 drives the plate gear seat 13 to move. The first driving source 21 is linked to the connecting rod seat 15.

[0043] The welding mechanism includes a welding connecting rod 16, which is movably connected to the plate tooth seat 13. The movable connection can be a rotating connection, a bearing fit, a connecting rod structure, or other movable connection methods. When the welding connecting rod 16 moves, the welding connecting rod 16 will drive the plate tooth seat 13 to move.

[0044] In the first state, the first driving source 21 drives the lower tooth plate 14 to move along the first direction, which is specifically the direction toward the bottom mold 12. That is, when the connecting rod seat 15 moves, the plate tooth seat 13 is driven to move. Since the lower tooth plate 14 is linked with the plate tooth seat 13, the lower tooth plate 14 also moves at this time, forming the effect that the lower tooth plate 14 moves toward the bottom mold 12. During use, the cable tie is placed above the bottom mold 12. When the lower tooth plate 14 moves, the cable tie is located between the lower tooth plate 14 and the bottom mold 12, forming a fitting effect. Here, the surface where the lower tooth plate 14 and the bottom mold 12 cooperate is the prior art, so it is not described in this embodiment. In addition, in this embodiment, the first direction specifically refers to the vertical up and down direction. Taking the three-dimensional coordinate axis as an example, the first direction is the Z-axis direction, that is, the lower tooth plate 14 moves vertically up and down along the Z-axis direction. The first driving source 21 directly drives the lower tooth plate 14 to move vertically up and down along the Z-axis direction. For example, the first driving source 21 is located directly above, and its output force is along the Z-axis direction, forming a reciprocating action effect.

[0045] In the second state, the welding mechanism drives the lower tooth plate 14 to reciprocate along the second direction, and the welding mechanism drives the lower tooth plate 14 to reciprocate, forming a friction welding effect. Here, the second direction is a horizontal direction, which can be the Y-axis direction or the X-axis direction. In this embodiment, taking the X-axis direction as an example, the welding mechanism drives the lower tooth plate 14 to reciprocate along the X-axis direction to form a friction welding effect. The plate tooth seat 13 and the connecting rod seat 15 are movably connected, and the plate tooth seat 13 and the welding connecting rod 16 are also movably connected. In the first state, the driving mechanism drives the lower tooth plate 14 to move toward the bottom mold 12 along the first direction to form a pressure effect. At this time, the cable tie is located between the bottom mold 12 and the lower tooth plate 14; in the second state, the welding mechanism drives the lower tooth plate 14 to reciprocate along the second direction to form a friction welding effect, thereby realizing the welding and fixing of the cable tie. In this structure, the two mechanisms are completely separated, and the first driving source directly drives the lower tooth plate to move, forming a direct force, which can accurately control the pressure and improve the welding efficiency.

[0046] Specifically, as attached Figure 3-4 As shown, the body 11 includes a frame 22, and the frame 22 is connected and fixed with the base 23. The frame 22 is provided with a second chamber 221, and the driving mechanism also includes a piston 24 and a screw sleeve 25. The piston 24 is accommodated in the second chamber 221, and the piston 24 is provided with a third chamber 241. The lower end of the piston 24 is connected with the connecting rod seat 15, and the piston 24 and the connecting rod seat 15 can be bolted or snap-on. The screw sleeve 25 is accommodated in the third chamber 241, and the first driving source 21 includes a screw rod 211, and the screw rod 211 cooperates with the screw sleeve 25. When the first driving source 21 is in motion, the screw rod 211 cooperates with the screw sleeve 25, so that the piston 24 moves, the piston 24 drives the connecting rod seat 15 to move, and the connecting rod seat 15 drives the plate tooth seat 13 and the lower tooth plate 14 to move together. In addition, the output end of the first driving source 21 can also be directly linked with the piston 24 to drive the piston 24 to move vertically up and down.

[0047] Specifically, as attached Figure 3-4 As shown, the driving mechanism further includes a limiting member 26, which limits the movement of the screw sleeve 25 in the axial direction. At this time, the screw sleeve 25 can only rotate in the radial direction.

[0048] Specifically, as attached Figure 3-4 As shown, the driving mechanism also includes a limiting member 26, which is connected to the upper end of the third chamber 241, and the limiting member 26 is fitted with the top surface of the screw sleeve 25. The setting of the limiting member 26 forms a fixing effect of the screw sleeve 25. When the screw rod 211 cooperates with the screw sleeve 25, a thread force is formed to make the piston 24 move. At this time, the first driving source 21 drives the screw rod 211 to rotate to achieve the effect of vertical up and down movement of the piston 24. By calculating the number of turns of the thread rotation, the size of the relevant force can be accurately obtained, which improves the effect of accuracy and also improves the welding quality. In this embodiment, the limiting member 26 can be a gasket.

[0049] Specifically, as attached Figure 3-4 As shown, the piston 24 is provided with a protrusion 242, and the bottom surface of the second chamber 221 is located on the movement track of the protrusion 242. The protrusion 242 forms a limiting effect, so that the piston 24 moves within a limited stroke.

[0050] Specifically, the first driving source 21 may be a cylinder or a motor, etc.

[0051] Specifically, as attached Figure 3As shown, it also includes a steel ball holder 17, and the connecting rod seat 15 is provided with a first chamber 151, and the steel ball holder 17 and the plate tooth seat 13 are accommodated in the first chamber 151, and the steel ball holder 17 is located between the inner wall of the first chamber 151 and the plate tooth seat 13. Here, the number of steel ball holders 17 is two, and the plate tooth seat 13 and the connecting rod seat 15 are limited on the Y axis by the provision of the two steel ball holders 17. At this time, the plate tooth seat 13 can slide relative to the connecting rod seat 15 in the X axis direction. The steel ball holder forms an active connection between the plate tooth seat 13 and the connecting rod seat 15. At this time, under the action of the steel ball holder, the plate tooth seat 13 can also move relative to the connecting rod seat 15. In addition, the connecting rod seat 15 and the plate tooth seat 13 can also be connected in a sliding rail type or a pendulum type.

[0052] Specifically, as attached Figure 1-4 As shown, the welding mechanism includes a second driving source 18 and an eccentric shaft 19, and the welding connecting rod 16 is sleeved on the eccentric shaft 19. When the eccentric shaft 19 rotates, it drives the welding connecting rod 16 to rotate, so that the welding connecting rod 16 forms a swing effect. The second driving source 18 is linked with the eccentric shaft 19. The setting of the eccentric shaft 19 forms a swing effect of the welding connecting rod 16, forming a reciprocating motion, so that a friction effect is formed between the lower tooth plate 14 and the bottom mold 12.

[0053] Specifically, as attached Figure 1-4 As shown, the second drive source 18 is connected to the eccentric shaft 19 by a pulley or a gear set. The linkage effect between the second drive source 18 and the eccentric shaft 19 is formed by different connection methods. In this embodiment, the pulley connection between the second drive source 18 and the eccentric shaft 19 is used as an example for description. The output end of the second drive source 18 is connected to the first synchronous pulley 181, the eccentric shaft 19 is connected to the second synchronous pulley 191, and the first synchronous pulley 181 and the second synchronous pulley 191 form a linkage relationship through a belt. Here, the diameter ratio of the first different pulley to the second synchronous pulley 191 can be adjusted according to actual needs.

[0054] Specifically, as attached Figure 1-2As shown, the body 11 includes a welding bracket 20, and the second driving source 18 is connected to the welding bracket 20. The second driving source 18 is connected to the welding bracket 20 to form a modular structure, which makes installation more convenient. Here, the second driving source 18 and the welding bracket 20 are bolted. The second driving source 18 can be a cylinder or a motor, etc. It should be noted that the welding bracket 20 is located above the base 23, and there is a connection relationship between the welding bracket 20 and the base 23, and the two are independently arranged. Further, the welding bracket 20 and the second driving source 18 cooperate with one end to be provided with a first accommodating chamber 201, and the first synchronous pulley 181 is accommodated in the first accommodating chamber 201. The first accommodating chamber 201 is provided with a hole, and the output end of the second driving source 18 is connected and fixed to the first synchronous pulley 181 through the hole to form a linkage effect. One end of the welding bracket 20 that cooperates with the eccentric shaft 19 is provided with two legs 202, and a through slot is provided between the two legs 202, and the through slot is oriented toward the connecting rod seat 15, that is, it is open in the X-axis direction. Both legs 202 are provided with a first through hole 203, and the eccentric shaft 19 is sleeved with a first bearing 192 and a second bearing 193, and the first bearing 192 is located between the inner wall of the first through hole 203 and the eccentric shaft 19, and the number of the first bearings 192 is two, and the front end of the eccentric shaft 19 passes through the first bearing 192 and is connected to the second synchronous pulley 191. The second bearing 193 is located in the middle position of the eccentric shaft 19, and the welding connecting rod 16 is sleeved on the second bearing 193. When the eccentric shaft 19 rotates, the second bearing 193 will drive the welding connecting rod 16 to rotate.

[0055] Specifically, the welding connecting rod 16 is rotatably connected to the plate tooth seat 13. The rotatable connection is specifically a pin connection, that is, the pin passes through the welding connecting rod 16 and cooperates with the plate tooth seat 13 to form a relative connection effect. Here, one end of the welding connecting rod 16 is sleeved on the eccentric shaft 19, and the other end of the welding connecting rod 16 is rotatably connected to the plate tooth seat 13.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
