The high-strength PVC film production equipment and the production method thereof comprise a base, a vertical plate, a cleaning mechanism, a linkage mechanism, a gluing mechanism and a guide mechanism. The guide mechanism is arranged on the base, and the vertical plate is vertically arranged on the base. The high-strength PVC film production equipment and the production method thereof are matched with the base, the vertical plate, the cleaning mechanism, the linkage mechanism, the gluing mechanism and the guide mechanism.

Description

Technical Field

[0001] This invention relates to the field of PVC film production equipment technology, specifically to a high-strength PVC film production equipment and its production method. Background Technology

[0002] Plastic films play a vital role in economic development and daily life. The development trend of newly developed plastic films both domestically and internationally is towards high performance, low cost, harmlessness, environmental friendliness, and ease of use. Reinforced plastic film, a lightweight film product with excellent mechanical properties, has replaced traditional plastic films and other materials in many fields, with its application range and usage continuously increasing. Advertising, packaging materials, agricultural greenhouses, and transparent curtains all require PVC reinforced plastic film to enhance transparency and provide a strong three-dimensional perspective and aesthetic appeal.

[0003] For example, Chinese patent disclosure "PVC Colored Plastic Transparent Mesh Film" (patent number: CN201220533376.5) includes a polyester fiber mesh, the upper and lower surfaces of which are tightly bonded to a PVC film layer, and a colored film is tightly bonded to the PVC film layer. This invention, composed of two PVC film layers bonded with a polyester fiber mesh, greatly enhances transparency and produces a strong three-dimensional perspective effect. Because of the tightly bonded colored film to the PVC film layer, this invention also has a more aesthetically pleasing effect and can be widely used in advertising, packaging materials, agricultural greenhouses, and transparent door curtains.

[0004] However, during the production process of the aforementioned patent, due to its double-sided bonding, impurities may be directly sealed into the film. Since conventional product quality inspection is often carried out after double-sided bonding, it is easy for defects and impurities to appear when the film product has already dried and bonded, thus having to be scrapped, indirectly increasing the scrap rate.

[0011] Preferably, the glue-applying mechanism includes a primary glue-rolling roller, a secondary glue-rolling roller, and two extrusion mechanisms. Both extrusion mechanisms are on the same side as the second roller and fixed to the upright plate. The secondary glue-rolling roller is pivotally connected to the upright plate. The first PVC outer film is located between the secondary glue-rolling roller and the third guide roller. The discharge port of the extrusion mechanism located at the higher position corresponds to the surface of the secondary glue-rolling roller. The primary glue-rolling roller is pivotally connected to the upright plate, and the second PVC outer film and the mesh fabric are located between the primary glue-rolling roller and the first guide roller.

[0012] Preferably, the adhesive application mechanism further includes a collection funnel disposed on top of the primary roller. The top opening of the collection funnel corresponds to the PVC outer film between the secondary roller and the guide roller.

[0013] Preferably, the guiding mechanism further includes guide wheel one, guide wheel two, and guide wheel three.

The electric telescopic rod is symmetrically and obliquely arranged on both sides of the base, and the sensor assemblies are disposed on the movable ends of the electric telescopic rods.

[0018] Step 1: First, pull out roller 1 and let it contact the mesh fabric through guide roller 1. At the same time, the first-stage roller on the other side of the mesh fabric will work.

[0019] Step 2: As the primary roller rotates, the glue extrusion mechanism applies glue to the primary roller, causing the mesh fabric to bond with the primary roller.

[0020] Step 3: Next, the bonded primary roller and mesh continue to move upwards. At this time, the sensor assembly and light box are activated. The light box shines light onto the primary roller and mesh, and the sensor assembly determines whether there are any impurities adhering to the mesh or the primary roller based on the shadow distribution.

[0021] Step 4: When impurities are confirmed, the electric telescopic rod retracts, allowing space for the sensor assembly. Then, the suction fan and drive slider move, aligning the limit bracket with the location of the impurity.

[0022] Step 5: Next, the electric telescopic crossbar extends, bringing the limiting bracket into contact with the mesh fabric, and then the universal joint is activated. Adjust the angle of the telescopic suction tube, then extend the tube, and the suction fan operates to suck out the impurities.

[0023] Step Six: After cleaning the primary roller and mesh, continue moving upwards. Apply adhesive to the bottom surface of guide wheel three using the secondary roller and adhesive extrusion mechanism, then allow guide wheel three to adhere to the mesh and primary roller.

[0024] Step 7: Simultaneously, excess glue on the guide wheel 3 and the secondary roller falls into the collection funnel under its own gravity. It then drips along the funnel into the primary roller, completing the secondary recycling of the glue.

[0025] Step 8: Next, the glued fabric is fed into the take-up roller as the clamp head pulls.

This invention allows for the inspection of the adhesive on one side after gluing and timely removal of any impurities, facilitating user operation. Attached Figure Description

[0038] This invention provides a high-strength PVC film production equipment and its production method, such as... Figure 1-8 As shown, the system includes a base 1, a vertical plate 14, a cleaning mechanism 7, a linkage mechanism 11, an adhesive application mechanism 31, and a guiding mechanism 23. The guiding mechanism 23 is mounted on the base 1, and the vertical plate 14 is vertically mounted on the base 1. Both the linkage mechanism 11 and the guiding mechanism 23 are mounted on the vertical plate 14. The cleaning mechanism 7 is mounted on the base 1. The guiding mechanism 23 includes roller 2, a winding mechanism 4, roller 8, PVC outer film 9, PVC outer film 15, mesh fabric 25, a tall column 18, and a short column 21. The winding mechanism 4 is mounted on the base 1, and the tall column 18 and short column 21 are symmetrically mounted vertically on the base 1 with the winding mechanism 4 as the center. Roller 2 is pivotally connected to the short column 21, one end of PVC outer film 15 is wound around roller 2, and roller 8 is pivotally connected to the tall column 18. One end of PVC outer film 9 is wound around roller 8, and one end of mesh fabric 25 is disposed within the winding mechanism 4. PVC outer membrane 19 and PVC outer membrane 25 are located on both sides of the mesh fabric 25, and the glue coating mechanism 31 corresponds to PVC outer membrane 19 and guide wheel 13.

[0039] The reason why the adhesive is applied to the bottom surface of the fabric in this invention is that the excess adhesive will fall off the bottom surface of the fabric under the influence of gravity, and the adhesive will not contaminate the top surface of the fabric.

[0040] Compared to traditional two-sided adhesive bonding methods, this invention allows the originally symmetrically arranged adhesive application mechanisms to be placed on the same side and at different heights. This means the adhesive at the higher position will drip directly onto the lower adhesive roller, achieving recycling. Compared to other traditional methods where adhesive drips into a collection box and is then recycled via conduction, this invention is simpler and more efficient.

[0041] The guiding mechanism 23 also includes a take-up roller 16, a guide cable 12, a linkage roller 13, and a clamping head 10.

The PVC outer film 9 is located between the secondary roller 28 and the guide roller 26. The discharge port of the higher extrusion mechanism 27 corresponds to the surface of the secondary roller 28. The primary roller 22 is pivotally connected to the vertical plate 14. The PVC outer film 15 and the mesh fabric 25 are located between the primary roller 22 and the guide roller 3. The discharge port of the lower extrusion mechanism 27 corresponds to the surface of the primary roller 22.

[0044] The adhesive application mechanism 31 also includes a collection funnel 29, which is disposed on top of the primary roller 22. The top opening of the collection funnel 29 corresponds to the PVC outer film 9 between the secondary roller 28 and the guide roller 26.

[0045] The guiding mechanism 23 also includes guide wheel 3, guide wheel 24, and guide wheel 26. Guide wheel 26 and guide wheel 24 are symmetrically arranged on both sides of the clamping head 10, and guide wheel 26 contacts the upper surface of the PVC outer film 9. Guide wheel 3 is pivotally connected to the vertical plate 14 and contacts the upper surface of the PVC outer film 15. Guide wheel 3 is symmetrical to the primary roller 22.

[0046] It also includes two sensor assemblies 6 and an electric telescopic rod 5. The electric telescopic rod 5 is symmetrically and diagonally arranged on both sides of the base 1, and the sensor assemblies 6 are arranged on the movable ends of the electric telescopic rods 5. The sensor assemblies 6 correspond to the mesh fabric 25 located between the secondary roller 28 and the primary roller 22.

[0047] It also includes a mounting bracket 19 and a light box 20. The mounting bracket 19 is mounted on the upright plate 14. The light box 20 is located at the bottom of the mounting bracket 19, and the light box 20 is symmetrical to the sensor assembly 6 about the mesh fabric 25.

[0048] The cleaning mechanism 7 includes a drive slider 33, an electric telescopic crossbar 17, a suction fan 32, a slide seat 34, a limiting bracket 30, a horizontal drive slider 36, a telescopic suction tube 35, and a drive universal joint 37. The drive slider 33 is slidably fitted onto the high column 18, and the slide seat 34 is mounted on the drive slider 33. The horizontal drive slider 36 is slidably fitted onto the slide seat 34, and the suction fan 32 is connected to the drive slider 33. The electric telescopic crossbar 17 is mounted on the drive slider 33, and the drive universal joint 37 is mounted on the movable end of the electric telescopic crossbar 17. The telescopic suction tube 35 is mounted on the drive universal joint 37 and communicates with the suction fan 32. The limiting bracket 30 is fitted onto the drive universal joint 37, and the limiting bracket 30 corresponds to the mesh openings of the mesh fabric 25.

[0049] A method for producing high-strength PVC film using equipment, comprising the following steps:

[0050] Step 1: First, pull out roller 2 and make contact with mesh fabric 25 through guide roller 3. At the same time, the first-stage roller 22 on the other side of mesh fabric 25 will work.

[0051] Step 2: As the primary roller 22 rotates, the glue extrusion mechanism 27 applies glue to the primary roller 22, so that the mesh fabric 25 is bonded to the primary roller 22.

[0052] Step 3: Next, the bonded primary roller 22 and mesh fabric 25 continue to move upwards. At this time, the sensor assembly 6 and the light box 20 are activated. The light box 20 illuminates the primary roller 22 and mesh fabric 25, and the sensor assembly 6 determines whether there are any impurities stuck to the mesh fabric 25 or the primary roller 22 based on the shadow distribution.

[0053] Step 4: When impurities are confirmed, the electric telescopic rod 5 retracts, and the sensor assembly 6 makes room. Then, the suction fan 32 and the drive slider 33 begin to move, aligning the limit bracket 30 with the location where the impurities appear.

[0054] Step 5: Next, the electric telescopic crossbar 17 extends, bringing the limiting bracket 30 into contact with the mesh fabric 25, and then the universal joint 37 is driven to work. Adjust the angle of the telescopic suction tube 35, then the telescopic suction tube 35 extends, and the suction fan 32 works to suck out the impurities.

[0055] Step Six: After cleaning the primary roller 22 and the mesh fabric 25, continue moving upwards. Apply glue to the bottom surface of the guide wheel 26 using the secondary roller 28 and the glue extrusion mechanism 27, and then let the guide wheel 26 adhere to the mesh fabric 25 and the primary roller 22.

[0056] Step 7: Simultaneously, excess glue on the guide wheel 26 and the secondary roller 28 falls into the collection funnel 29 under its own gravity. It then drips along the collection funnel 29 into the primary roller 22, completing the secondary recycling of the glue.

[0057] Step 8: Then, as the clamp head 10 pulls, the glued fabric is fed into the take-up roller 16.

[0058] In summary, this high-strength PVC film production equipment and method, through the coordinated operation of the base 1, upright plate 14, cleaning mechanism 7, linkage mechanism 11, glue application mechanism 31, and guiding mechanism 23, transforms the traditional method of simultaneously bonding the inner mesh surface after gluing both sides into a single-sided sequential bonding method. The advantage of this is that it effectively prevents impurities in the air from being adsorbed onto the adhesive; the two-sided bonding directly seals these impurities inside, and even if subsequent inspection reveals that the adhesive has dried, it can only be discarded as waste. Secondly, this invention allows for the detection and timely removal of impurities from the adhesive on one side after application, facilitating user operation.
