Description

Technical Field

[0001] This invention relates to the field of bag making, and in particular to a fully automatic high-speed bag making machine for pharmaceutical packaging bags. Background Technology

[0002] The films used in pharmaceutical packaging bags need to meet requirements such as sterility, high barrier properties, and sterilization resistance. They typically employ the following multi-layer composite film structures: aluminum-plastic composite bags for powders, granules, and blister packaging often use aluminum foil; transparent high-barrier film materials are often used for aseptic packaging that requires visibility, such as infusion bags and biological agents; medical-grade PE / PP materials are often used for the inner heat-sealing material of all medicines; and PVC / PVDC materials are often used for blister packaging of solid tablets.

[0003] A search revealed a Chinese patent (CN108312637A) disclosing plastic bag packaging production equipment, which includes a frame, a film winding mechanism, a film pressing mechanism, a punching mechanism, a film guiding mechanism, a 45-degree film transfer mechanism, a feeding mechanism, an opening mechanism, a heat sealing mechanism, a material pulling head mechanism, a clamping and folding mechanism, and a finished product receiving mechanism. The film on the film winding mechanism passes sequentially through the film pressing mechanism, the film guiding mechanism, the 45-degree film transfer mechanism, the feeding mechanism, the opening mechanism, and the heat sealing mechanism. The clamping and folding mechanism is located above the opening mechanism, the heat sealing mechanism is located on one side of the opening mechanism, and the material pulling head mechanism is located on the other side of the opening mechanism. The entire process of stacking, bagging, and sealing the product is completed by the machine, which has a high degree of automation and greatly reduces the footprint of the machine.

[0004] However, in actual use, the aforementioned patent relies mainly on the film's own weight to adhere to the tripod. The tension of the film can cause uneven tension on the top slope of the tripod, leading to tripod vibration and film deviation. Furthermore, the top slope of the tripod is in hard contact with the film, which can easily cause creases in the film and affect subsequent processing. Therefore, we propose a fully automatic high-speed bag making machine for pharmaceutical packaging bags. Summary of the Invention

[0005] The technical problem to be solved by this application is that the film mainly relies on its own gravity to adhere to the tripod. Due to the tension of the film, the tension on the top slope of the tripod is uneven, causing the tripod to vibrate. Furthermore, the top slope of the tripod is in hard contact with the film, which can easily cause creases in the film and affect the subsequent processing of the film.

[0006] In summary, this application provides a stamping die with a variable cavity, including a fixed frame and a driving mechanism. The fixed frame is connected to an inclined first triangular frame through the driving mechanism. The fixed frame is also equipped with a guide rod that passes through one side of the first triangular frame. A rotating roller with the same inclination as the inclined surface is rotatably installed on the inclined surface of the top of the first triangular frame. Multiple storage slots are arrayed on the outer side of the rotating roller. Each of the multiple storage slots is rotatably connected to an arc-shaped guide plate that is close to the edge of the rotating roller. Elastic members connected to the guide plates are also provided in the multiple storage slots.

[0007] In some embodiments, the drive mechanism includes a servo motor mounted inside a fixed frame, the output end of the servo motor being connected to a lead screw, and the outer side of the lead screw being threaded with a nut connected to the other side of the first tripod.

[0008] In some embodiments, two sets of cylinders are rotatably mounted on one end of the fixing frame, and two sets of rotating plates are also rotatably mounted on one end of the fixing frame. An unwinding roller for wrapping the composite film is rotatably connected between the two sets of rotating plates, and the output end of the cylinder is hinged to the top of the rotating plate away from the rotation point.

[0009] In some embodiments, a plurality of transverse film transfer rollers are rotatably mounted at one end of the fixed frame and between the first tripod and the unwinding roller, a vertical film transfer roller is rotatably mounted inside the fixed frame and at the end of the first tripod away from the transverse film transfer rollers, and an intermediate roller is rotatably mounted in the middle of the inside of the fixed frame.

[0010] In some embodiments, a mounting frame is installed inside the fixed frame near one end of the intermediate roller, and a slitting blade is mounted on the mounting frame.

[0011] In some embodiments, a second tripod is symmetrically mounted on the top and bottom of the mounting bracket, and a directional roller is rotatably mounted inside the fixing bracket near the top and bottom of the second tripod. The second tripod has the same tilt angle as the first tripod.

[0012] In some embodiments, a material guiding mechanism is provided at the other end of the fixing frame, and an edge sealing mechanism is provided at the other end of the material guiding mechanism.

[0013] In some embodiments, the other end of the edge sealing mechanism is provided with an edge cutter, and the other end of the edge cutter is provided with a slicing mechanism.

[0014] In some embodiments, the material guiding mechanism includes a support plate mounted on the other end of the fixed frame, and a redirecting roller, a tensioning roller, and a flat roller are rotatably mounted inside the support plate.

[0015] In some embodiments, a guide roller for wrapping and sealing a zipper is rotatably installed inside the support plate, two inclined plates are installed in a figure-eight shape inside the support plate, and two support rollers are rotatably installed inside the support plate.

[0016] This invention has at least the following beneficial effects: 1. Setting up an inclined tripod creates a gradual force transition, changes the direction of the membrane tension, decomposes the transverse stress of the membrane into axial and transverse forces, and, in conjunction with the guide rod, increases stability, reduces transverse stress, and prevents the membrane from deviating due to tripod vibration.

[0017] 2. Add a rotating roller with the same slope as the tripod at the inclined surface. When the film turns, it contacts the rotating roller, changing sliding friction into rolling friction, eliminating local stress concentration, and avoiding creases caused by hard contact between the film and the inclined surface of the tripod.

[0018] 3. Multiple arc-shaped guide plates are set on the outside of the rotating roller. The guide plates are elastically supported by elastic elements. When the film passes through the rotating roller, the guide plates that have turned to the inside of the film are squeezed into the receiving groove of the rotating roller by the film. The guide plates that just come into contact with the film are unfolded by the elastic force of the elastic elements to provide progressive support for the film. The bending curvature can be adjusted for different films, so that the strain energy is released evenly, the entire stress distribution is stably eliminated, and wrinkles caused by residual oscillation of the film are avoided.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a technical solution: a stamping die with variable cavity, including a fixed frame 1 and a driving mechanism 2. The fixed frame 1 is connected to a first triangular frame 3 with an inclined arrangement through the driving mechanism 2. The fixed frame 1 is also equipped with a guide rod 4 that passes through one side of the first triangular frame 3. A rotating roller 5 with the same inclination as the inclined surface is rotatably installed on the inclined surface at the top of the first triangular frame 3. Multiple storage slots 501 are arrayed on the outer side of the rotating roller 5. Each of the multiple storage slots 501 is rotatably connected to an arc-shaped guide plate 6 that is close to the edge of the rotating roller 5. An elastic element 7 connected to the guide plate 6 is also provided in the multiple storage slots 501.

[0030] In the comparative document, the vertically placed tripod is affected by the tension of the film during film transfer. The uneven tension on the inclined surface of the ordinary tripod easily causes the tripod to vibrate. Even with limit blocks and limit frames, lateral vibration and shaking still occur. Long-term use can easily cause the film to deviate. The inclined first tripod 3 can disperse the tension and avoid vibration or shaking caused by excessive force on the top of the inclined surface, thereby reducing the probability of film deviation. The height of the first tripod 3 is adjusted by the drive mechanism 2 to make it suitable for films of different thicknesses and elasticities. The added guide rod 4 also plays a role in stabilizing the first tripod 3 when it is raised and lowered.

[0031] In the prior art, the film in direct, rigid contact with the inclined surface of the first tripod 3 is prone to creases. By adding a rotating roller 5 to the inclined surface, the film passes over the roller 5, changing sliding friction into rolling friction, eliminating local stress concentration, and avoiding creases caused by rigid contact.

[0032] When a conventional roller 5 reverses the direction of the film, residual vibrations are easily generated after the film detaches, causing a sudden change in the curvature of the film and resulting in wrinkles. A guide plate 6 is set on the outside of the roller 5 to support the film. The residual vibrations generated after the film detaches are transmitted to the guide plate 6, causing a continuous change in the curvature of the film so that the strain energy is released evenly through the guide plate 6, thereby avoiding wrinkles.

[0033] The guide plate 6 is set in an arc shape and has a receiving groove 501 to achieve smoother guidance of the film movement, reduce friction and resistance caused by sharp angle turning. When the guide plate 6 turns to the inside of the film, it can be completely stored in the receiving groove 501, avoiding the guide plate 6 occupying extra space outside the roller 5.

[0034] The function of the elastic element 7 (spring) is to enable the guide plate 6 to unfold after it is no longer under pressure, so that the guide plate 6 can fit the film when it first comes into contact with the film, and provide progressive support for the film.

[0035] Example 2: Based on Example 1, as follows Figure 4 As shown, the drive mechanism 2 includes a servo motor 201 installed inside the fixed frame 1. The output end of the servo motor 201 is connected to a lead screw 202. The outer side of the lead screw 202 is threaded with a nut 203 that is connected to the other side of the first tripod 3.

[0036] The comparison document shows that the height of the tripod is adjusted by using a stepper motor and a common lead screw. By replacing the stepper motor and the common lead screw with a servo motor 201, a lead screw 202, and a nut 203, the lateral vibration can be further suppressed compared to the stepper motor and the common lead screw.

[0037] Example 3: Based on Example 2, such as Figure 5 As shown, two sets of cylinders 8 are rotatably mounted on one end of the fixed frame 1, and two sets of rotating plates 9 are also rotatably mounted on the other end of the fixed frame 1. A roll-up roller 10 for wrapping the composite film is rotatably connected between the two sets of rotating plates 9. The output end of the cylinder 8 is hinged to the top of the rotating plate 9 away from the rotation point.

[0038] By setting cylinder 8 and rotating plate 9 to adjust the position of unwinding roller 10, the film tension can be finely adjusted, and film vibration can be dynamically compensated during production.

[0039] Example 4: Based on Example 3, such as Figure 5As shown, a plurality of transverse film transfer rollers 11 are rotatably mounted at one end of the fixed frame 1 and between the first triangular frame 3 and the unwinding roller 10. A vertical film transfer roller 12 is rotatably mounted inside the fixed frame 1 and at the end of the first triangular frame 3 away from the transverse film transfer rollers 11. An intermediate roller 13 is rotatably mounted in the middle of the inside of the fixed frame 1.

[0040] Example 5: Based on Example 4, such as Figure 5 and Figure 6 As shown, a mounting frame 14 is installed inside the fixed frame 1 near the intermediate roller 13, and a slitting knife 15 is mounted on the mounting frame 14.

[0041] The slitting blade 15 is located in the middle of the mounting bracket 14 and can cut a film with both sides printed on it into two films so that subsequent processing can be achieved.

[0042] Example 6: Based on Example 5, such as Figure 6 As shown, the top and bottom of the mounting frame 14 are symmetrically mounted with a second tripod 16. Inside the fixed frame 1, near the top and bottom of the second tripod 16, a directional roller 17 is rotatably mounted. The second tripod 16 has the same tilt angle as the first tripod 3.

[0043] The second tripod 16 serves to turn the two films so that the unprinted sides of the two films are bonded together, enabling subsequent processing. In practice, a proportionally proportioned rotating roller 5, a receiving groove 501, a guide plate 6, and an elastic element 7 can be added to the inclined surface of the second tripod 16 to reduce damage to the films.

[0044] Example 7: Based on Example 6, as follows Figure 7 As shown, the other end of the fixing frame 1 is provided with a material guiding mechanism 18, the other end of the material guiding mechanism 18 is provided with an edge sealing mechanism 19, the other end of the edge sealing mechanism 19 is provided with an edge cutter 20, and the other end of the edge cutter 20 is provided with a slicing mechanism 21.

[0045] In practice, multiple edge-sealing mechanisms 19 and slicing mechanisms 21 can be set to achieve continuous edge-sealing and slicing processing. The edge cutter 20 contacts both sides of the film to cut off the excess part of the film. Example 8: Based on Example 6, as follows Figure 8 As shown, the material guiding mechanism 18 includes a support plate 1801 installed at the other end of the fixed frame 1. Inside the support plate 1801, a redirecting roller 1802, a tensioning roller 1803, and a flat roller 1804 are rotatably installed. Inside the support plate 1801, a material guiding roller 1805 for wrapping and sealing a zipper is also rotatably installed. Inside the support plate 1801, two inclined plates 1806 are installed in a figure-eight shape. Inside the support plate 1801, two support rollers 1807 are also rotatably installed.

[0046] In specific implementation, a motor connected to the unwinding roller 10 is mounted on the fixed frame 1 to drive the unwinding roller 10 to rotate and feed the film. A correction mechanism and sensor are set in the area through which the film passes to detect and correct the film. The film is wound on the unwinding roller 10 and passes in sequence through the transverse transfer roller 11, the transfer roller 5, the vertical transfer roller 12, the intermediate roller 13, the second triangular frame 16, the directional roller 17, the redirecting roller 1802, the tension roller 1803, the flat roller 1804, the sealing mechanism 19, and the slicing mechanism 21. The sealing zipper passes through the inclined plate 1806 and the support roller 1807 and is located between two films with the front and back printed on them on the tension roller 1803.

[0047] Based on the above embodiments, the following is the complete working principle of the above embodiments: The film wound on the unwinding roller 10 passes through the transverse transfer roller 11, with the front and back printed on the bottom. After passing through the transfer roller 5, it changes from transverse to vertical. After passing through the vertical transfer roller 12 and the intermediate roller 13, it is cut into two films with the front and back printed on them by the slitting knife 15. After passing through the second tripod 16, the two films change from vertical to transverse and the two films with the unprinted front and back sides close to each other. When the two films pass through the directional roller 17, the redirecting roller 1802 and the tensioning roller 1803, the sealing zipper is pulled, so that the sealing zipper is placed between the two films through the inclined plate 1806 and the support roller 1807. The two films with the sealing zipper are heat-fused to the sealing zipper after passing through the sealing mechanism 19, and the bottom, top and side are heat-fused and sealed. After passing through the edge cutter 20, the excess part is cut off. After passing through the slicing mechanism 21, it is cut into individual packaging bags.
