When the product is loaded, it is initially placed on the workbench 101. In order to ensure that the packaging bag on the product can be accurately cut later, the position of the product needs to be positioned. The second pushing module 103 is configured to push the product in a direction perpendicular to the product transmission direction, that is, the second pushing module 103 can push the product from one side of the workbench 101 to the other side, so that the position of the product in the direction perpendicular to the transmission direction is determined, and then the first pushing module 102 is actuated to push the product to the second station along the product transmission direction.

[0038] The first film cutting mechanism 2 is arranged on the workbench 101, and can cut the packaging bags on both sides of the product when the product is pushed to the second station. Figure 3 and Figure 4 The first film cutting mechanism 2 includes: a first film cutting assembly 201 and a second film cutting assembly 202, a width adjustment assembly 203 and a height adjustment assembly 204, which are arranged on both sides of the workbench. The first film cutting assembly 201 and the second film cutting assembly 202 are used to cut product packaging bags respectively; the width adjustment assembly 203 is used to adjust the distance between the first film cutting assembly 201 and the second film cutting assembly 202 to adapt to products of different sizes; the height adjustment assembly 204 is used to simultaneously adjust the heights of the first film cutting assembly 201 and the second film cutting assembly 202 to adapt to products of different heights.

[0039] The first film cutting assembly 201 and the second film cutting assembly 202 both include: a mounting seat 2011, a guide mechanism 2012 and a cutter 2013 arranged on the mounting seat 2011; the guide mechanism 2012 is installed at the feeding end of the mounting seat 2011, and is used to make the product packaging bag enter the cutting range of the cutter 2013 when the product flows in; the cutter 2013 is installed at the discharging end of the mounting seat 2011, and is used to cut the product packaging bag. That is to say, by cooperating with the guide mechanism 2012 and the cutter 2013, the packaging bag of the product can be cut when the product flows in. Preferably, the end of the cutter 2013 facing the product has a sharp corner that can be inserted into the product packaging bag, and the cutter 2013 is provided with a V-shaped or U-shaped cutting area. When the sharp corner encounters a product with a packaging bag, the product packaging bag can be inserted and introduced into the cutting area, so that the product packaging bag can be cut. By arranging the first film cutting assembly 201 and the second film cutting assembly 202 on both sides of the workbench 101, the packaging bags on both sides of the product can be cut simultaneously when the product moves.

[0040] Preferably, the guide mechanism 2012 is connected to the mounting seat 2011 via a rotating shaft, that is, the cutter 2013 can be fine-tuned in a small range of angles according to product conditions during actual operation, thereby adapting to different usage environments.

[0041] Furthermore, the first film cutting assembly 201 and the second film cutting assembly 202 further include a buffer mechanism 2014 and a fixing block 2015, one end of the buffer mechanism 2014 is connected to the mounting seat 2011, and the other end of the buffer mechanism 2014 is connected to the fixing block 2015. In other words, the fixing block 2015 is installed at the movable end of the height adjustment assembly 204, and the buffer mechanism 2014 can provide a buffer for the cutter 2013 on the mounting seat 2011, so that the product can be avoided at an appropriate time to avoid damage to the product caused by hard contact.

[0042] like Figure 3 As shown, the width adjustment component 203 can adopt a cylinder or servo drive and a linear slide, so as to drive one of the first film cutting component 201 and the second film cutting component 202 to move, and the other of the first film cutting component 201 and the second film cutting component 202 is fixedly arranged on the workbench 101. That is to say, one of the first film cutting component 201 and the second film cutting component 202 is fixedly arranged, and the other is movably arranged, and the cutting width adjustment of the first film cutting mechanism 2 can be realized by adjusting the movably arranged film cutting component.

[0043] The height adjustment assembly 204 includes: a first height guide mechanism 2041 connected to the first film cutting assembly 201, a second height guide mechanism 2042 connected to the second film cutting assembly 202, and a height drive mechanism 2043 for controlling the simultaneous lifting and lowering of the first film cutting assembly 201 and the second film cutting assembly 202. In other words, the first film cutting assembly 201 and the second film cutting assembly 202 are controlled by the height drive mechanism 2043 to lift and lower at the same time, ensuring that the first film cutting assembly 201 and the second film cutting assembly 202 are always kept at the same height. The height drive mechanism 2043 can be a servo motor, and the first height guide mechanism 2041 and the second height guide mechanism 2042 use a screw rod, and the height drive mechanism 2043 can drive the screw rod to move through a conveyor belt and a transmission wheel.

[0044] Please refer to Figure 5 and Figure 6 The upper film removal device includes: a second film cutting mechanism 4, which is used to cut the packaging bag in a direction perpendicular to the product transmission direction, so as to cut the packaging bag into two parts, an upper film and a lower film; a second transmission mechanism 5, which is used to limit the product of the packaging bag to be cut in a preset area before the second film cutting mechanism 4 is actuated, and push the product to the third station after removing the upper film; an upper film removal mechanism 6, which is used to pick up the upper film of the product and transfer it to the recycling area after the second film cutting mechanism 4 is actuated.

[0045] The second film cutting mechanism 4 and the upper film removing mechanism 6 are driven by the same driving mechanism 7, that is, the second film cutting mechanism 4 and the upper film removing mechanism 6 are integrated at the movable end of the driving mechanism 7. When working, the second film cutting mechanism 4 and the upper film removing mechanism 4 are simultaneously driven to the top of the product, the second film cutting mechanism 4 first performs the cutting action, after the cutting is completed, the second film cutting mechanism 4 is reset, and the driving mechanism 7 drives the second film cutting mechanism 4 and the upper film removing mechanism 6 to further descend, so that the upper film removing mechanism can smoothly pick up the upper film, after the upper film is picked up, the driving mechanism drives the second film cutting mechanism and the upper film removing mechanism to move to the recovery area, and the upper film removing mechanism puts down the upper film to complete the upper film removal operation of the product.

[0046] Key References Figure 6, the second transmission mechanism 5 includes a first positioning module 501 arranged at the front end of the packaging bag product to be cut, a second positioning module 502 arranged on one side of the product, a limiting plate 503 arranged on the other side of the product, and a third pushing module 504 arranged at the rear end of the product for cooperating with the first positioning module 501, the second positioning module 502 and the limiting plate 503 to position the product, and the third pushing module 504 is also configured to push the product to the next station, i.e., the third station 300. Specifically, the front end refers to the end where the product is located in the forward direction, close to the next station, and the rear end refers to the end opposite to the forward direction of the product, close to the previous station. The first positioning module 501 is located at the front end and can push and position the product backward, and the third pushing module 504 is located at the rear end and can push and position the product forward. One side of the product refers to the end perpendicular to the product transmission direction, and the limiting plate 503 located on one side is set in a fixed position as a reference position. The second positioning module 502 located on the other side can move in a direction perpendicular to the transmission direction, thereby pushing the product toward the limiting plate 503. Therefore, the product is pushed by the first positioning module 501, the second positioning module 502 and the third pushing module 504, and then cooperates with the limiting plate to achieve the positioning of the product. When cutting, the product can also be clamped to avoid displacement of the product position.

[0047] After the upper film is removed, the product needs to continue to move forward to the next station, i.e., the third station. Therefore, the first positioning module 501 at the front end is preferably arranged above the product and controlled by a lifting mechanism. When the limit is required, it descends and performs related operations, and rises to avoid when the product moves forward. Before the product is loaded, it needs to be transferred from the previous station, i.e., the first station. Therefore, the third pushing module 504 at the rear end is driven to rise or fall by a mechanism that can control the lifting and lowering. When it is in the descending position, the height is consistent with the product placement platform, and it can be used as a platform to support the movement of the product. When it is in the ascending position, the height is higher than the product placement platform, and the product can be pushed forward along the product placement platform. Further, the first positioning module 501 and the second positioning module 502 both include: a driving cylinder and a limit push rod arranged at the movable end of the driving cylinder. The third pushing module 504 includes: a pushing platform, a lifting drive that drives the pushing platform to rise or fall, and a pushing drive that drives the pushing platform to move forward or backward.

[0048] Reference Figure 7, the lower film removal device includes: a film stripping mechanism 8, a supporting platform 9, a third transmission mechanism 10 and a film removal mechanism (not shown in the figure), wherein the supporting platform 9 is used to carry products, the products have a lower film of a packaging bag, the film stripping mechanism 8 is arranged around the supporting platform 9, and is used to strip the lower film of the product on the supporting platform 9; the third transmission mechanism 10 is used to transfer the product after the lower film is removed to the next process, and the film removal mechanism 11 is used to transfer the lower film after the product is removed to the recycling area. Specifically, after the supporting platform 9 receives the product with the upper film removed transferred from the second station 200, the film stripping mechanism 8 strips / teares the lower film of the product, and then the third transmission mechanism 10 pushes the product after the film is stripped to the next process, which is usually the feeding 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 9 and places it in the recycling area, and the entire lower film removal process is completed.

[0049] Continuing to refer to the figure, the support platform 9 is driven by the lifting mechanism to rise or fall relative to the film removal mechanism 8, and the film removal mechanism 8 presses down the lower film of the product while the support platform 9 rises. The lifting mechanism preferably adopts servo, screw, linear module, etc.

[0050] Continue to refer to Figure 7 The film stripping mechanism 8 includes a first comb tooth bar 801 located at the front end of the product, a second comb tooth bar 802 located at both sides of the product, a third comb tooth bar 803 located at the rear end of the product, and a guide plate 804 arranged around the support platform 9. The first comb tooth bar 801, the second comb tooth bar 802, and the third comb tooth bar 803 are each driven by a comb tooth bar drive 805 to extend and retract relative to the guide plate 804. That is to say, the first comb tooth bar 801, the second comb tooth bar 802, and the third comb tooth bar 803 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 801, the second comb tooth bar 802, and the third comb tooth bar 803 can smoothly extend into the gap between the products without interfering with the products, the first comb tooth bar 801, the second comb tooth bar 802, and the third comb tooth bar 803 are connected to the movable end of the comb tooth bar drive 805 through an elastic member. When the first comb teeth 801, the second comb teeth 802 and the third comb teeth 803 extend, they can press the lower film if they encounter a gap between products, and retract under force if they touch products, crushing or damaging the products. The comb teeth drive 805 preferably adopts a cylinder, the movable end of the comb teeth drive 805 preferably adopts a mounting plate, and the elastic member preferably adopts a spring.

[0051] Further, in order to use products of different sizes, the telescopic range of one of the first comb tooth bar 801 and the third comb tooth bar 803 is greater than the other of the first comb tooth bar 801 and the third comb tooth bar 803; and / or, the telescopic range of one of the two sets of second comb tooth bars 802 is greater than the other. It is preferred to increase the telescopic range of the third comb tooth bar 803 and one of the second comb tooth bars 802 located at the rear end. By controlling these two sets of comb tooth bars, the telescopic range can be adjusted according to the size of the product, thereby improving the adaptability range of the demoulding mechanism 8. Of course, when the product size is different, the height is also different. Therefore, the lifting mechanism that controls the lifting of the support platform 9 will also adjust the support platform 9 to the corresponding height as needed. Similarly, the width of the stripping platform 9 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 by a semi-automatic method such as a screw rod and a locking rod. 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 804 can be adjusted by setting a servo motor, or manually. In this way, the guide plate 804 and the comb teeth can be compatible with products of various specifications and sizes on the market.

[0052] In another specific embodiment, the first comb teeth bar 801 and the two groups of second comb teeth bars 802 are driven by cylinders, the third comb teeth bar 803 is driven by a servo, and the stroke of the third comb teeth bar 803 driven by the servo is greater than the stroke of other comb teeth bars driven by cylinders.

[0053] Preferably, the third transmission mechanism 10 is driven by a linear module to reciprocate between the support platform and the entrance of the next process, such as a vibration plate, so as to transfer the product after film removal to a subsequent process.

[0054] Reference Figure 7 The third transmission mechanism 10 includes: a first blocking module 1001 located at the front end of the product, a second blocking module 1002 located at one side of the product, a third blocking module 1003 located at the other side of the product, and a fourth blocking module 1004 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 transfer the product after film removal out of the supporting platform 9.

[0055] Preferably, the first blocking module 1001, the second blocking module 1002 and the third blocking module 1003 all include a baffle and a baffle drive for controlling the extension and retraction of the baffle. The movement of the baffle is controlled by the baffle drive, and the range of the third transmission mechanism 10 can be adjusted as needed to use products of different sizes.

[0056] Reference Figure 7, the fourth material-blocking module 1004 includes: a limit baffle, a vertical drive for controlling the lifting and lowering of the limit baffle, and a limit baffle drive for controlling the vertical drive and the extension and retraction of the limit baffle in the horizontal direction. Among them, the vertical drive includes a cylinder and a cylinder guide, so that the limit baffle can be lifted and lowered under the drive of the cylinder, and the limit baffle drive can push the limit baffle after the film is removed, so that the limit baffle clamps the product. Specifically, when the product with the lower film is pushed into the supporting platform, the limit baffle is lowered by the cylinder to limit the rear end of the product, and during the entire process of the supporting platform rising, the limit baffle is simultaneously lifted up, so as to limit and protect the rear end of the product during the entire film tearing process.

[0057] 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. 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.

[0058] Continue to refer to Figure 1-7 , the working process of the utility model is:

[0059] The first station 100:

[0060] The feeding device 3 feeds the product with the packaging film to the first station 100, that is, the workbench 101 of the first conveying mechanism 1. The first pushing module 102 and the second pushing module 103 cooperate to position the product and push the product to the second station 200. In the process of transferring the product to the second station 200, the first film cutting assembly 201 and the second film cutting assembly 202 located on both sides of the workbench 101 can simultaneously cut the packaging bags on both sides of the product when the product moves.

[0061] Second station 200:

[0062] After the product is sent to the second station 200, the second film cutting mechanism 4 cuts the packaging bag of the product perpendicular to the product transmission direction. Then, the second transmission mechanism 5 clamps the product along the four sides, and the upper film removal mechanism 6 sucks out the cut upper film and discharges it to the recycling area such as the upper film collection box. After the upper film is taken out, the first positioning module 501 and the second positioning module 502 of the second transmission mechanism 5 release the product at the same time. The third pushing module 504 sends the product to the third station to complete the entire upper film removal operation.

[0063] The third station 300:

[0064] After the product is pushed into the supporting platform 9, the limiting baffle in the fourth blocking module 1004 of the third transmission mechanism 10 rises to limit the rear end of the product. The supporting platform 9 rises to a first height position, where the bottle mouth of the product is slightly higher than the front end and the comb teeth on the left and right sides.

[0065] Next, the first comb teeth bar 801 and the second comb teeth bar 802 are driven by the comb teeth bar driver 805 to block the packaging film at the front end and the left and right sides of the product. The supporting platform 9 continues to rise to the second height position. At this position, the bottle mouth of the product is slightly higher than the third comb teeth 803 at the rear end. Then, the third comb teeth 803 extend to block the film at the rear end of the product. Next, the supporting platform 9 continues to rise to the highest pushing position. In this process, the first comb teeth bar 801, the second comb teeth bar 802 and the third comb teeth 803 located on the surroundings block and tear off the packaging bags around the product. At the same time, the product is sent to the third transmission mechanism 10 at the top. The third transmission mechanism 10 is activated to limit all products and push the products to the next process, such as the platform of the drug loading production line.

[0066] Finally, the film removal mechanism moves to remove the lower film remaining on the support platform 9.
