Detailed Implementation

[0035] 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.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] like Figures 1-2 As shown, a heat-sealing plate assembly for a packaging machine includes: a sliding seat 1, a lower plate 2, an upper plate 3, and a plate drive mechanism 4, wherein: the sliding seat 1 moves back and forth towards the heat-sealing head under the drive of the plate drive mechanism 4; the lower plate 2 is connected to the sliding seat 1; the upper plate 3 is located above the lower plate 2 and is slidably connected to the lower plate 2, and the width of the upper plate 3 along the direction of the strapping is greater than the width of the lower plate 3, so that the front and rear blades below the plate assembly can press the strapping onto the upper plate 3; a support frame 5 is connected to the frame of the packaging machine and is used to support the plate drive mechanism 4, and the sliding seat 1 is connected to the support frame 5 through a linear bearing 6;

[0039] like Figure 4 Specifically, the skateboard drive mechanism 4 includes a drive motor 41, a drive wheel 42, and a roller 43, wherein the drive wheel 42 is connected to the transmission end of the drive motor 41; the roller 43 is located at a non-center position of the drive wheel, and in this embodiment, the roller 43 is close to the outer side of the drive wheel 42.

[0040] like Figures 1-4 As shown, the sliding seat 1 is provided with a guide rail 11, and the roller 43 is located inside the guide rail 11. When the drive wheel 42 rotates, the roller 43 applies force to the guide rail 11, thereby causing the sliding seat 1 to drive the lower slide plate 2 to move. This structure is simple, easy to assemble, and not prone to failure. By using the roller 43 to move inside the guide rail 11, the roller 43 rotates during the movement, which can reduce the force on the roller 43 and the guide rail 11 in other directions and avoid damage to the roller 43.

[0041] As a further embodiment, the lower slide plate 2 is provided with fixed pins 21 on both sides, and the upper slide plate 3 is provided with elongated slot through holes 31 on both sides relative to the fixed pins 21, and the fixed pins 21 move back and forth in the elongated slot through holes 31.

[0042] When the fixing pins 21 on both sides of the lower slide plate 2 move to one end of the elongated slot through hole 31, the upper slide plate 3 is moved under the action of the slide plate drive mechanism 4, and cooperates with the heating head to complete the heating and bonding work.

[0043] like Figure 3 As shown, in this embodiment, the sliding plate 2 further includes: a groove 22, a head groove 23, and a head stop 24. The groove 22 is located at the end of the sliding plate 2 facing the hair dryer and has an open structure. The head groove 23 is located above the groove 22. The head stop 24 is located at the end of the head groove 23 from which the belt exits.

[0044] In the initial state, both the lower slide plate 2 and the upper slide plate 3 are above the blade assembly. The cable tie first passes through the tape groove 22, then through the tape channel, and finally the tape head enters the tape head groove 23, where the tape head is limited by the tape head stop block 24. The cable tie is divided into two layers in the tape groove 22 and the tape head groove 23. The blade assembly rises, with the front blade pressing the upper layer of cable tie head onto the upper slide plate 3. After the tightening mechanism tightens the cable tie, the rear blade in the blade assembly presses the lower layer of cable tie onto the upper slide plate 3, and the heat exchanger head penetrates into the tape groove. In groove 22, the lower slide plate 2 retracts under the action of the sliding drive assembly 4, and the middle blade of the rear blade in the blade assembly rises, pressing the lower cable tie between the middle blade and the heating head. The heating head heats and melts the lower cable tie. The heating head retracts, and the middle blade continues to rise, pressing the lower cable tie and the upper tape head against the upper slide plate 3, so that the lower cable tie and the upper tape head are bonded together. At this time, the fixing pin 21 moves to the rear end of the elongated groove through hole 31, and under the action of the slide plate drive mechanism, it drives the upper slide plate 2 to move backward, completing the entire heat bonding process.

[0045] The heating head and blade assembly in this utility model are existing technologies and will not be described in detail here.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
