[0016] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The above and / or additional aspects and advantages of the present invention will become apparent and easily understood from the description of the embodiments in conjunction with the following drawings, in which:

[0018] Figure 1-3 It is a schematic diagram of the three-dimensional structure of the lower film removal device in the embodiment of the utility model. DETAILED DESCRIPTION

[0019] The lower film removal device according to an embodiment of the first aspect of the utility model is described below with reference to the accompanying drawings.

[0020] like Figures 1 to 3As shown, the lower film removal device of the present application includes: a film stripping mechanism 1, a supporting platform 2, a pushing mechanism 3 and a film removal mechanism (not shown in the figure). Among them, the supporting platform 2 is used to carry products, and the products have a lower film of a packaging bag. The film stripping mechanism 1 is arranged around the supporting platform 2, and is used to strip the lower film of the product on the supporting platform 2; the pushing mechanism 3 is used to transfer the product after the lower film is stripped to the next process, and the film removal mechanism is used to transfer the lower film after the product is removed to the recycling area. In other words, after the supporting platform 2 receives the product, the film pushing mechanism 1 first strips / teares the lower film of the product, and then the pushing structure 3 pushes the product after the film is stripped to the next process. The next process is usually the feed end of an external device such as a vibrating plate. Finally, the film removal mechanism picks up the lower film remaining on the supporting platform 2 and places it in the recycling area, and the entire lower film removal process is completed.

[0021] Continue to refer to Figures 1 to 3 , the supporting platform 2 is driven by the lifting mechanism 4 to rise or fall relative to the film stripping mechanism 1, and the film stripping mechanism 1 presses down the lower film of the product while the supporting platform 2 rises. Alternatively, the film stripping mechanism 1 is driven by the lifting mechanism 4 to rise or fall relative to the supporting platform 2, and the film stripping mechanism 1 presses down the lower film of the product while it falls. In other words, by controlling the relative movement of the supporting platform 2 and the film stripping mechanism 1 in the vertical direction, the lower film on the product is pressed down to the bottom of the product, completing the film stripping action. In order to save costs and improve efficiency, the lifting mechanism 4 is preferably arranged at the supporting platform 2 to control the supporting platform 2 to rise or fall, and the film stripping mechanism 1 remains fixed in the vertical direction, and the lower film is stripped while the supporting platform 2 rises. Furthermore, the lifting mechanism 4 preferably adopts a servo, a screw rod, a linear module, etc.

[0022] Key References Figure 2, the film stripping mechanism 1 includes a first comb-tooth bar 11 located at the front end of the product, a second comb-tooth bar 12 located on both sides of the product, a third comb-tooth bar 13 located at the rear end of the product, and a guide plate 14 arranged around the support platform 2. The first comb-tooth bar 11, the second comb-tooth bar 12 and the third comb-tooth bar 13 are each driven by a comb-tooth bar drive 15 to extend and retract relative to the guide plate 144. That is to say, the first comb-tooth bar 11, the second comb-tooth bar 12 and the third comb-tooth bar 13 are extended only when film stripping is required, and press the lower film on the product, and return to the original position after film stripping is completed. In order to ensure that the first comb-tooth bar 11, the second comb-tooth bar 12 and the third comb-tooth bar 13 can smoothly extend into the gap between the products without interfering with the products, the first comb-tooth bar 11, the second comb-tooth bar 12 and the third comb-tooth bar 13 are connected to the movable end of the comb-tooth bar drive 15 through an elastic member. When the first comb teeth 11, the second comb teeth 12 and the third comb teeth 13 extend, they can press the lower film if they encounter a gap between products, and retract under force if they touch products to avoid crushing or damaging the products. The comb teeth drive 15 preferably adopts a cylinder, the movable end of the comb teeth drive 15 preferably adopts a mounting plate, and the elastic member preferably adopts a spring.

[0023] Furthermore, in order to use products of different sizes, the telescopic range of one of the first comb teeth bar 11 and / or the third comb teeth bar 14 is greater than the other of the first comb teeth bar 11 and the third comb teeth bar 13; and / or, the telescopic range of one of the two sets of second comb teeth bars 12 is greater than the other. It is preferred to increase the telescopic range of the third comb teeth bar 13 and one of the second comb teeth bars 12 located at the rear end. By controlling these two sets of comb teeth bars, the telescopic range can be adjusted according to the size of the product, thereby improving the adaptability range of the demoulding mechanism 1. Of course, when the product size is different, the height is also different. Therefore, the lifting mechanism 4 that controls the lifting of the support platform 2 will also adjust the support platform 1 to the corresponding height as needed. Similarly, the width of the support platform 2 is adjustable and can be adjusted as needed. Specifically, it can be adjusted automatically by means of a cylinder, a servo, etc., or it can be adjusted semi-automatically by means of a screw rod, a locking rod, etc. The above setting can be compatible with products of different specifications and achieve rapid changeover. Of course, in order to be compatible with a wider range of products, the position of the guide plate 804 is adjustable, and the position of the guide plate 14 can be adjusted by setting a servo motor, or manually. In this way, the guide plate 14 and the comb teeth can be compatible with products of various specifications and sizes on the market.

[0024] In another specific embodiment, the first comb teeth bar 11 and the two groups of second comb teeth bar 12 are driven by a cylinder, and the third comb teeth bar 13 is driven by a servo, and the stroke of the third comb teeth bar 13 driven by the servo is greater than the stroke of the first comb teeth bar 11 and the two groups of second comb teeth bar 12 driven by the cylinder.

[0025] Preferably, the pushing mechanism 3 is driven by a linear module 5 to reciprocate between the supporting platform 2 and the entrance of the next process, such as a vibration plate, so as to transfer the product after film removal to the subsequent process.

[0026] Reference Figure 2 and Figure 3 The pushing mechanism 3 includes: a first blocking module 31 located at the front end of the product, a second blocking module 32 located at one side of the product, a third blocking module 33 located at the other side of the product, and a fourth blocking module 34 located at the rear end of the product. The four groups of blocking modules can cooperate to wrap and clamp the product after film removal, and move the product after film removal to the discharging platform.

[0027] Preferably, the first blocking module 31, the second blocking module 32 and the third blocking module 33 all include a baffle 311 and a baffle drive 312 for controlling the extension and retraction of the baffle 311. The movement of the baffle 311 is controlled by the baffle drive 312, and the range of the pushing mechanism 3 can be adjusted as needed to use products of different sizes.

[0028] Reference Figure 3 , the fourth material blocking module 34 includes: a limit plate 341, a vertical drive 342 for controlling the lifting and lowering of the limit plate 341, and a limit plate drive 343 for controlling the vertical drive 342 and the limit plate 341 to extend and retract in the horizontal direction. Among them, the vertical drive 342 includes a cylinder and a cylinder guide, so that the limit plate 341 can be lifted and lowered under the drive of the cylinder, and the limit plate drive 343 can push the limit plate 341 after the film is removed, so that the limit plate 341 clamps the product. Specifically, when the product with the lower film is pushed into the supporting platform 2, the limit plate 341 is lowered by the cylinder to limit the rear end of the product, and during the entire process of the supporting platform 1 rising, the limit plate 341 is simultaneously lifted up, so as to limit and protect the rear end of the product during the entire film tearing process.

[0029] The film removal mechanism includes an adsorption component and an adsorption drive. The adsorption drive has vertical and horizontal degrees of freedom, and can drive the adsorption component to the top of the supporting platform 2. After the adsorption component picks up the lower film, it drives the adsorption component together with the lower film to the recovery area. After the adsorption component places the lower film in the recovery area, it returns to its original position or repeats subsequent actions.

[0030] The present application also provides a product packaging bag cutting production line, comprising the lower film removing device as described above.
