Description

Technical Field

[0001] This invention relates to the field of stretch film technology, and more specifically to a stretch film processing system and processing method. Background Technology

[0002] Stretch film, also known as wrap film, is a packaging method that uses mechanical stretching devices or manual stretching to forcibly stretch a film at room temperature to tightly wrap goods for easy transportation and storage. It is a commonly used packaging form internationally. In market applications, while thinner stretch films have better tensile strength, they have lower folding resistance and often clump together after being removed, making them difficult to untangle. Furthermore, to achieve a certain strength, methods such as altering the material ratio of the stretch film or adding reinforcing ribs of other materials are often used. However, these methods are more expensive and can easily affect the properties of the stretch film itself, potentially impacting the contents when wrapping pharmaceuticals or chemical substances. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a stretch film processing system and processing method, which has the advantage of being able to process thin stretch films that can be easily separated after being removed and crumpled into a ball.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A stretch film processing system includes a housing, a horizontal wire mechanism installed inside the housing, a vertical wire mechanism fixed to the left side of the horizontal wire mechanism, a wire-blocking mechanism and a film-adhesive mechanism installed inside the housing, wherein the film-adhesive mechanism is located on the left side of the vertical wire mechanism and the wire-blocking mechanism is located on the upper side of the vertical wire mechanism.

[0006] The transverse wire mechanism includes a transverse wire platform, with wire feeding blocks A fixedly connected to both sides of the transverse wire platform. Wire feeding blocks B are fixedly connected to the inner sides of the two wire feeding blocks A. Multiple transverse wire sliders are slidably connected to the outer sides of the wire feeding blocks B. The multiple transverse wire sliders are all wrapped around the outer sides of the corresponding wire feeding blocks B. A feeding block is fixedly connected to the right side of the transverse wire platform.

[0007] Each of the aforementioned horizontal wire sliders includes a horizontal wire vertical plate, on which a horizontal wire movable plate is slidably connected. One end of an electric telescopic rod is fixedly connected to the horizontal wire movable plate, and the other end of the electric telescopic rod is fixedly connected to a horizontal wire pull block.

[0008] Each of the aforementioned transverse wire pulling blocks is provided with a material holding T-groove, and the opening of the material holding T-groove is provided with a chamfer.

[0009] A baffle plate is fixedly connected inside the wire mesh table, and a cooling plate is provided on the upper side of the baffle plate. The cooling plate is fixedly connected to the upper side of the wire mesh table.

[0010] The longitudinal wire mechanism includes a feeding pool. Four longitudinal wire rotating rods are rotatably connected to the inside of the feeding pool, and a feeding belt is wound around the four longitudinal wire rotating rods. A scraper is fixed to the left side of the feeding pool and is located on the upper left side of the feeding belt.

[0011] The feeding belt is provided with a longitudinal wire feeding groove, and the scraper is provided with protrusions corresponding to the longitudinal wire feeding groove.

[0012] The wire-blocking mechanism includes two wire-blocking plates, which are symmetrically fixed to the front and rear sides of the housing, and a wire-blocking plate is inserted between the two wire-blocking plates.

[0013] The membrane-adhesion mechanism includes a membrane-adhesion stage, a heating device is installed inside the membrane-adhesion stage, and control plates are fixedly connected to both the front and rear sides of the membrane-adhesion stage. Two membrane rollers and two adjusting shafts are rotatably connected between the two control plates, and the two membrane rollers are both located between the two adjusting shafts.

[0014] A method for processing stretch film using a stretch film processing system, the method comprising the following steps:

[0015] a: Add the liquid film material into the cross-fiber table and the feed tank respectively, and place the film to be processed on the film roller on the right side;

[0016] b: Start the horizontal wire mechanism to pull the horizontal wire out from inside the horizontal wire table;

[0017] c: Start the longitudinal wire mechanism to pull the longitudinal wire out from inside the feed tank and combine it with the transverse wire;

[0032] like Figure 2-3 As shown:

[0033] A stretch film processing system includes a housing 100, a horizontal wire mechanism 200 installed inside the housing 100, a vertical wire mechanism 300 fixed to the left side of the horizontal wire mechanism 200, a wire-blocking mechanism 400 and a film-adhesive mechanism 500 installed inside the housing 100, the film-adhesive mechanism 500 being disposed on the left side of the vertical wire mechanism 300, and the wire-blocking mechanism 400 being disposed on the upper side of the vertical wire mechanism 300.

[0034] Before the stretch film processing system is put into use, the operator can add liquid film material into the horizontal filament mechanism 200 and the vertical filament mechanism 300 respectively, and then place the film to be processed in the film-adhesive mechanism 500, thus completing the preparation work before the use of the stretch film processing system; then the horizontal filament mechanism 200 can be started, so that the internal liquid film material can be pulled out of the horizontal filaments and the pulled horizontal filaments can be moved to the left. Then the vertical filament mechanism 300 can be started, so that the internal liquid film material can be pulled out of the vertical filaments and the horizontal filaments moving to the left can be combined and adhered. Then the combined horizontal filaments and vertical filaments can continue to move to the left. Then the film-adhesive mechanism 500 can be started, so that the film to be processed can be adhered to the combined horizontal filaments and vertical filaments, thus producing the finished stretch film. The produced finished stretch film can be wound into a roll by the film-adhesive mechanism 500, thus completing the processing of the finished stretch film.

[0035] Meanwhile, the wire-blocking mechanism 400 can guide the combination of the pulled-out horizontal and vertical wires during the processing, thereby preventing the horizontal and vertical wires from failing to stick together and combine. This ensures that the position of the horizontal and vertical wires on the finished stretch film is stable, and ensures that the properties of each part of the finished stretch film are similar when it is kneaded into a ball. This also avoids the phenomenon that some areas of the finished stretch film cannot be separated after it is kneaded into a ball.

[0036] like Figure 4-5 , Figure 8 As shown:

[0037] The transverse wire mechanism 200 includes a transverse wire platform 210, with wire feeding blocks A220 welded to both sides of the transverse wire platform 210. Wire feeding blocks B230 are connected to the inner sides of the two wire feeding blocks A220 by screws. Multiple transverse wire sliders 240 are arranged between the wire feeding blocks A220 and the wire feeding blocks B230. The multiple transverse wire sliders 240 are all connected to the outer side of the corresponding wire feeding block B230 by a conveyor belt. A feeding block 250 is connected to the right side of the transverse wire platform 210 by screws.

[0038] Before using the cross-thread mechanism 200, the operator can add liquid film material into the cross-thread table 210. Then, the operator can start the conveyor belt, which will drive multiple cross-thread sliders 230 to move. This will cause the cross-thread sliders 230 located on both sides of the cross-thread table 210 to move to the left. At the same time, the loading block 250 will be started, which will draw the liquid film material from inside the cross-thread table 210 to the outlet of the loading block 250. The liquid film material will be poured onto the cross-thread sliders 230 located directly below the outlet of the loading block 250. This will cause the cross-threads to be pulled out between the two opposing cross-thread sliders 230. Then, the cross-thread sliders 230 can continue to move to the left and be driven upward by the cross-thread table 210, thereby transporting the pulled cross-threads above the longitudinal threads. This completes the cross-thread pulling and transporting work of the cross-thread mechanism 200.

[0039] Meanwhile, since the conveyor belt is arranged in a ring, the two opposite horizontal wire sliders 230 that have completed one horizontal wire pulling and conveying operation can continue to move with the conveyor belt and return to the feed block 250 outlet, thus completing the horizontal wire pulling and conveying operation in a cycle until all the wrapping film processing is completed.

[0040] like Figure 6 As shown:

[0041] Each of the multiple horizontal wire sliders 240 includes a horizontal wire vertical plate 241. A horizontal wire movable plate 242 is slidably connected to the horizontal wire vertical plate 241. One end of an electric telescopic rod 243 is connected to the horizontal wire movable plate 242 by screws. The other end of the electric telescopic rod 243 is connected to a horizontal wire pull block 260 by screws.

[0042] When the two opposing transverse wire sliders 240 move to the same position as the outlet of the feeding block 250, the two electric telescopic rods 243 can be extended, so that the transverse wire pulling blocks 260 at the other end of the two electric telescopic rods 243 can move together to the lower end of the outlet of the feeding block 250, so that the feeding block 250 can simultaneously pour liquid film onto the two opposing transverse wire pulling blocks 260. Then, the two electric telescopic rods can be shortened, so that the liquid film on the two transverse wire pulling blocks 260 can be stretched, thereby pulling out the transverse wires.

[0043] When the horizontal wire slider 240 moves to the left along the edge of the horizontal wire platform 210, the horizontal wire platform 210 gradually rises from right to left, thereby allowing the horizontal wire movable plate 242 to gradually rise, so that the pulled horizontal wire can be lifted close to the upper surface of the horizontal wire platform 210, thus enabling the horizontal wire to be transported to the left, and then the horizontal wire and the longitudinal wire can be combined to complete the pulling and transporting of the horizontal wire.

[0044] like Figure 7 As shown:

[0045] Each of the multiple horizontal wire pulling blocks 260 is provided with a material holding T-groove 261, and the side opening of the material holding T-groove 261 is provided with a chamfer 262; thereby, the liquid film material poured down by the material block 250 can be temporarily stored inside the material holding T-groove 261. At the same time, when the corresponding two horizontal wire pulling blocks 260 pull the horizontal wire, the chamfer 262 can play a guiding role, so that the liquid film material can be evenly pulled out from the material holding T-groove 261 along the edge of the chamfer 262, thereby preventing the pulled horizontal wire from breaking and being damaged during the pulling and transportation process.

[0046] like Figure 9 As shown:

[0047] A baffle plate 211 is welded inside the wire-threading stage 210. A cooling plate 212 is provided on the upper side of the baffle plate 211. The cooling plate 212 is connected to the upper side of the wire-threading stage 210 by screws. Liquid film material is placed on the lower side of the baffle plate 211. Since the baffle plate 211 can divide the interior of the wire-threading stage 210 into upper and lower cavities, it can prevent the liquid film material from entering the upper cavity and affecting the start-up of the cooling plate 212. At the same time, the baffle plate 211 can prevent the liquid film material added to the lower cavity of the wire-threading stage 210 from overflowing.

[0048] Meanwhile, when the drawn crosswire moves to the left along the upper side of the crosswire platform 210, the activated cooling plate 212 can cool the crosswire, thereby condensing the liquid film material and obtaining a semi-solid crosswire, thus preventing the crosswire from breaking during the drawing process.

[0049] like Figure 10 As shown:

[0050] The longitudinal wire mechanism 300 includes a feeding pool 310. Four longitudinal wire rotating rods 320 are rotatably connected to the inside of the feeding pool 310 via a rotating motor. A feeding belt 330 is wound around the four longitudinal wire rotating rods 320. A scraper 340 is welded to the left side of the feeding pool 310 and is located on the upper left side of the feeding belt 330.

[0051] Before the longitudinal filament mechanism 300 is started, the operator can place the liquid film material inside the feeding pool 310, so that the lower side of the feeding belt 330 is immersed in the liquid film material. Then, the rotating motor is started, which drives the longitudinal filament rotating rod 320 to rotate counterclockwise. This drives the feeding belt 330 to rotate counterclockwise, thus bringing the liquid film material to the upper side of the feeding belt 330. The feeding belt 330 then pulls the liquid film material into longitudinal filaments. The pulled longitudinal filaments can remain relatively stationary with the transverse filaments during the movement, allowing the longitudinal filaments to adhere and combine with the transverse filaments, thereby completing the pulling and moving combination of the longitudinal filaments.

[0052] Further:

[0053] The feeding belt 330 is provided with a longitudinal filament feeding groove 331, and the scraper 340 is provided with a protrusion corresponding to the longitudinal filament feeding groove 331. Thus, the liquid film material being moved upward by the feeding belt 330 can be drawn into longitudinal filaments through the longitudinal filament feeding groove 331. At the same time, when the longitudinal filaments that have been drawn and bonded with the transverse filaments move to the longitudinal filament rotating rod 320 on the upper left side, the protrusion on the scraper 340 can penetrate into the longitudinal filament feeding groove 331, thereby removing the longitudinal filaments from the longitudinal filament feeding groove 331, thereby separating the longitudinal filaments from the feeding belt 330, and allowing the bonded transverse and longitudinal filaments to enter the film adhesion mechanism 500.

[0054] like Figure 11 As shown:

[0055] The wire-blocking mechanism 400 includes two wire-blocking plates 410, which are symmetrically welded to the front and rear sides of the outer shell 100. A wire-blocking plate 420 is inserted between the two wire-blocking plates 410. The wire-blocking plate 420 can block and guide the horizontal wires moving to the left, allowing the horizontal wires to move to the left along the lower side of the wire-blocking plate 410. This allows the horizontal wires to adhere to the pulled-out longitudinal wires, ensuring that the horizontal and longitudinal wires are bonded together. This ensures that the horizontal and longitudinal wires on the finished wrapping film are in stable positions, and that the properties of each part of the finished wrapping film are similar when it is kneaded into a ball. This also avoids the phenomenon that some areas of the finished wrapping film cannot be separated after it is kneaded into a ball.

[0056] like Figure 12 As shown:

[0057] The adhesive membrane mechanism 500 includes an adhesive membrane stage 510, which is equipped with a heating device. Control plates 520 are welded to both the front and rear sides of the adhesive membrane stage 510. Two membrane rollers 540 are rotatably connected between the two control plates 520 through a stepper motor and a synchronous gear. Two adjusting shafts 530 are rotatably connected between the two control plates 520 through a bearing. The two membrane rollers 540 are both located between the two adjusting shafts 530.

[0058] Before the film-adhesion mechanism 500 is started, the operator can move the movable end of the film to be processed on the right film roller 540 around the outside of the two adjustment shafts 530 and then connect it to the left film roller 540. After the combined horizontal and vertical filaments move to the right side of the film-adhesion table 510, the stepper motor can be started, thereby driving the left film roller 540 to rotate. The left film roller 540 then drives the film to be processed between the two adjustment shafts 530 to move from right to left, thereby driving the combined horizontal and vertical filaments to move from right to left. At the same time, the heating device can be started to soften the film to be processed, the horizontal and vertical filaments, and allow them to adhere together, thus producing the finished wrap film. The finished wrap film can pass over the outside of the left adjustment shaft 530 and wrap around the left film roller 540, thus completing the adhesion of the finished wrap film.

[0059] A method for processing stretch film using a stretch film processing system includes the following steps:

[0060] a: Add the liquid film material into the cross-beam table 210 and the feed tank 310 respectively, and place the film to be processed on the film roller 540 on the right side;

[0061] b: Start the horizontal wire mechanism 200, so that the horizontal wire mechanism 200 pulls the horizontal wire out from inside the horizontal wire table 210;

[0062] c: Start the longitudinal wire mechanism 300, so that the longitudinal wire mechanism 300 pulls the longitudinal wire out from the inside of the feed pool 310 and combines it with the transverse wire;

[0063] d: Start the film adhesion mechanism 500 so that the film to be processed can adhere to the assembled horizontal and vertical filaments and be wound on the film roller 540 on the left side, thereby obtaining the finished wrap film;

[0064] Because the finished stretch film has horizontal and vertical filaments bonded on one side, it can maintain a certain degree of folding resistance during bending and rubbing, thus ensuring that the finished stretch film is easier to separate after being rubbed into a ball.

[0065] Meanwhile, the thickness of most areas of the finished stretch film is the same as the original film to be processed, which can reduce the weight of the finished stretch film after adding horizontal and vertical yarns, thereby reducing the raw material consumption during the processing of the finished stretch film and thus reducing the production cost of the finished stretch film.
