[0035] In a specific embodiment of the utility model, the rotation rebound assembly 25 includes a first spring 251, a second spring 252, an inner sleeve 253 and an outer sleeve 254. The first spring 251 is arranged on the upper part of the sliding frame 24, and the two ends are fixedly connected to the sliding frame 24 and the inner sleeve 253 respectively. The second spring 252 is arranged on the lower part of the sliding frame 24, and the two ends are fixedly connected to the sliding frame 24 and the outer sleeve 254 respectively. The top of the adjustment chamber 211 is provided with an upper slide groove 214, and the bottom is provided with a clearance groove 215 to prevent the outer sleeve 254 from interfering with the bracket 21. One end of the inner sleeve 253 is vertically slidably mounted on the sliding frame 24, and the other end is rotatably mounted in the upper slide groove 214 and slides along the setting direction of the upper slide groove 214. One end of the outer sleeve 254 is vertically slidably mounted on the sliding frame 24, and penetrates the sliding frame 24 and is slidably sleeved on the inner sleeve 253, and the other end is hinged in the clearance groove 215.

[0036] In this embodiment, the sliding frame 24 is arranged horizontally, the outer sleeve 254 is perpendicular to the sliding frame 24, and the upper slide groove 214 is arranged perpendicular to both the outer sleeve 254 and the sliding frame 24.

One end of the second spring 252 away from the sliding frame 24 is connected to one end of the outer sleeve 254 close to the clearance groove 215.

[0037] In a specific embodiment of the present utility model, the stacking rack 4 includes a retaining column 41, a push handle 42, a frame body 43 and a guiding rack 44. Universal wheels are provided at the bottom of the frame body 43, and a stacking groove 431 is arranged on the frame body 43. The guiding rack 44 for guiding the packaging film 9 is detachably installed in the stacking groove 431. One end of the retaining column 41 is fixed on the frame body 43, and the push handle 42 is installed at the other end. The retaining column 41 for changing the movement direction of the packaging film 9 is vertically arranged at a position opposite to the discharge port 12.

[0038] In this embodiment, the guiding racks 44 are arranged on both sides of the stacking groove 431, and the packaging film 9 is limited and stacked between the two guiding racks 44. The cross-section of the guiding rack 44 in the vertical direction is a right trapezoid. Above the guiding table 14 of the support base 1, there is also a guiding table for limiting the finished packaging film 9. The included angle between the lower surface of the guiding table and the horizontal plane is greater than the included angle between the guiding table 14 and the horizontal plane, which can prevent the finished packaging film 9 from flying out of the preset direction and guide the finished packaging film 9 to smoothly slide out from the discharge port 12.

[0039] Compared with the prior art, this thermoforming packaging machine for automatic stacking of finished products can automatically control the deflection and straightening of the bracket 21 in the support transfer assembly 2 through the cooperation of the guiding seat 13 on the support base 1 and the support transfer assembly 2, so that the finished packaging film 9 placed on the bracket 21 automatically slides off the bracket 21. Through the cooperation of the guiding table 14 and the retaining column 41 and the guiding rack 44 in the stacking rack 4, the automatically sliding finished packaging film 9 automatically falls into the stacking groove 431 and is automatically stacked in sequence in the vertical direction. Through the sliding setting of the supporting block 22 in the support transfer assembly 2, the limitation and relaxation of the finished packaging film 9 can be automatically realized, so as to facilitate the transfer of the packaging film 9 and the free sliding of the packaging film 9. Through the setting of the rotary spring-back assembly 25, the automatic deflection and straightening of the bracket 21 can be realized. The structure is simple and the operation is convenient. The finished products can be stacked automatically and simply, effectively improving the work efficiency.

[0040] The working process of the thermoforming packaging machine for automatic stacking of finished products of the present utility model is as follows: Hold the push handle 42 and move the frame body 43 with the guiding rack 44 corresponding to the finished product installed to a position close to the discharge port 12. Start the feeding machine 5, the thermoforming machine 6, the cutting machine 7, the receiving machine 8, the support transfer assembly 2 and the lifting driver 3. After the raw material comes out of the feeding machine 5, it is subjected to thermoforming treatment by the thermoforming machine 6 and then moves to the support base 1. At this time, the top of the bracket 21 is flush with the top of the support base 1 and abuts against the bottom of the packaging film 9 at the same time.

[0041] Start the lifting drive member 23 to eject the supporting block 22 to engage with the groove on the formed packaging film 9. Start the cutting machine 7 to cut the packaging film 9. The lifting drive 3 is started to drive the supporting and transporting assembly 2 supporting the packaging film 9 to move down into the accommodating cavity 11. At this time, the waste edge is wound up by the material collecting machine 8. The bracket 21 descends driven by the lifting drive 3. During the descent, the lifting drive member 23 is started to drive the supporting block 22 to move down until the top of the supporting block 22 is flush with the top of the bracket 21, and the packaging film 9 loses its limit. When one end of the bracket 21 abuts against the guiding seat 13, when the bracket 21 continues to move down driven by the lifting drive 3, it will deflect according to the setting direction of the guiding seat 13. At this time, the first spring 251 on one side of the supporting block 22 is compressed, and the second spring 252 is stretched. The first spring 251 on the other side of the supporting block 22 is stretched, and the second spring 252 is compressed. After the lifting drive 3 moves in place, it stops moving. Before moving in place, the bracket 21 deflects and slightly collides with the material guiding table 14. A rubber pad is provided at the position where the bracket 21 abuts against the material guiding table 14. After the slight collision between the two, the packaging film 9 slides obliquely downward along the top of the bracket 21 under the action of the inertia of sudden stop and its own gravity. After the packaging film 9 slides out, it slides out from the discharge port 12 after being guided by the material guiding table 14, collides with the stop post 41, and after slightly rebounding, it is guided by the guiding frame 44 and stacked into the stacking groove 431. After the packaging film 9 slides out, the lifting drive 3 is started to drive the bracket 21 to move up, and the bracket 21 gradually separates from the guiding seat 13. At this time, under the action of the rebound of the first spring 251 and the second spring 252, the bracket 21 automatically returns to the correct position. When the stacking groove 431 is stacked with enough finished products, operate the push handle 42 to move the stacking rack 4 out, and replace the stacking rack 4 without stacked finished products to continue stacking finished products.

[0042] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0043] The above-described embodiments are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
