Description

Technical Field

[0001] The embodiments of the present invention relate to the field of packaging machinery, and in particular to a composite device for making porous materials. Background Art

[0002] The laminating machine is used to bond two or more layers of materials into one with adhesive. For example, the lamination of film and aluminum foil, film, paper, and non-woven fabric is often used and is widely used in the flexible packaging industry.

[0003] In the existing compound machine technology, if there are through holes on the material, when the material with through holes needs to be coated with glue, the through holes on the material will cause the glue to leak to the side of the material that is not coated with glue, and the leaked glue will also stick to the equipment during the transmission process, so that the other side of the material is stained with glue and the equipment is not clean. And the existing compound machine is mainly composed of a frame, a first feeding mechanism, a transition roller, a second feeding mechanism, a compounding mechanism and a receiving mechanism. Since this combination is fixed, in order to prevent the glue on the material with through holes from leaking, it is necessary to add a cushion film. The existing compound machine cannot meet the simultaneous feeding of the three mechanisms, and in the process of conveying the material, the material will have different tensions, and the position will deviate during the compounding process. Since the equipment cannot detect it, many wrinkles will appear on the final product, or the fitting position will be staggered, which will affect the product quality and cause resource waste. Therefore, a compound mechanism for making porous materials is needed to solve this problem. Summary of the invention

[0004] The purpose of the present invention is to provide a composite device for making porous materials. When one side of the material is coated with glue, a cushion film can be added to the side not coated with glue, so that the material will not leak to the other side of the material when the glue is applied, and the glue passing through the through hole will directly cover the cushion film. And when the material is composited, it is possible to ensure that the position of the material will not be offset during the composite process.

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0053] Figure 1 It is a front view of the composite device for making porous materials in the first embodiment of the present invention; Figure 2 It is a partial side view of the composite device for making porous materials in the first embodiment of the present invention; Figure 3 The material path diagram of the first material, the second material and the third material in the first embodiment of the present invention; Figure 4 This is a controller connection diagram of the composite device for making porous materials in the first embodiment of the present invention; Figure 5 This is a rendering of the first material and the second material in the first compounding mechanism in the first embodiment of the present invention. A compounding device for making a porous material in this embodiment can be used for compounding three materials, and can determine whether the material is offset during the conveying process through detection, thereby realizing the compounding of multiple materials.

[0054] A composite device for making porous materials in this embodiment includes: a frame 1, a first feeding mechanism 2, a second feeding mechanism 3, a third feeding mechanism 4, a first receiving mechanism 5, a first compounding mechanism 6, a second compounding mechanism 7, a second receiving mechanism 8, a first resistance detection device 9, a second resistance detection device 10 and a controller, wherein the frame 1 further includes: a crossbeam 103, a left bracket 101 and a right bracket 102. The left bracket 101 and the right bracket 102 are vertically arranged at both ends of the crossbeam 103, respectively.

[0055] The first feeding mechanism 2 is used to feed out the first material, which is a cushion film, which can be a transparent film. The first material receiving mechanism 5 is used to collect the first material after use. The second feeding mechanism 3 is used to feed out the second material, which has a plurality of through holes, which can be round or square. The third feeding mechanism 4 is used to feed out the third material, and the second material receiving mechanism 8 is used to collect the material after the second material and the third material are combined. The second feeding mechanism 3 is arranged on the lower right side of the left bracket 101 and is fixed to the left bracket 101 through a fixing plate. The first compounding mechanism 6 is located on the left side of the second feeding mechanism 3 and is fixed to the middle of the left bracket 101. The first compounding mechanism 6 includes: a first compound active roller 601 and a first compound driven roller 602, which are arranged side by side up and down, and the first compound driven roller 602 is located above the first compound active roller 601. The first material comes out of the first feeding mechanism 2 , and the second material comes out of the second feeding mechanism 3 , and they are respectively transported by a plurality of transition rollers and enter the first compounding mechanism 6 .

[0056] It should be noted that the first composite active roller 601 is connected to a driving device (not shown in the figure), and the driving device can be a reduction motor or an AC servo motor. The reduction motor drives the first composite active roller 601 to rotate, thereby pulling the composited first material and the second material to rotate. After the first material and the second material enter the composite mechanism 6, the composite process begins. The first material and the second material are brought into the first composite mechanism 6 under the action of the first composite active roller 601. Since the first material and the second material are in contact with the first composite driven roller 602, relative friction is generated with the first composite driven roller 602, driving the first composite driven roller 602 to operate.

[0057] A coating roller 20 is provided on the left bracket, and the coating roller 20 is located at the lower left of the first composite active roller 601. The coating roller 20 is arranged tangentially to the first composite active roller 601. There is a glue box (not shown) on one side of the coating roller 20, and the glue box contains coating glue, and the coating glue is used to coat the second material with glue. The coating roller 20 is in contact with the glue in the glue box, so that it can be ensured that the coating roller 20 is covered with glue. Since a reduction motor is fixed to the first composite active roller 601, the first composite active roller 601 is arranged tangentially to the coating roller 20 and contacts each other. Therefore, during the rotation of the first active roller 601, the mutual friction between the contact surfaces drives the coating roller 20 to rotate, and the coating roller 20 contacts the glue. Driven by the first composite active roller 601, the coating roller 20 starts to rotate.

[0058] The coating roller 20 starts to rotate. During the rotation of the coating roller 20, the surface of the coating roller 20 is all adhered with glue. During the process of the first composite active roller 601 driving the coating roller 20 to rotate, the coating roller 20 transfers the glue covering the surface to the first composite active roller 601. When the first material and the second material enter the first composite mechanism 6, the first material is located above the second material, so the first material contacts the first composite driven roller 602, and the second material contacts the first composite active roller 601, that is, the first material contacts and composites with the reverse side of the second material, and the front side of the first material contacts the first composite active roller 601. In addition, because the first composite active roller 601 has glue on it after contacting the coating roller 20, when the first composite active roller 601 contacts the front side of the second material, the front side of the second material will be coated with glue. When the first composite active roller 601 applies glue to the front side of the second material, the first material covers the back side of the second material, so the glue on the front side of the first material will not leak to the back side of the second material, and the glue applied on the round holes will be directly applied to the first material because the back side of the second material is padded with the first material.

[0059] Under the co-extrusion of the first composite active roller 601 and the first composite driven roller 602, the first material gradually covers the second material being coated with glue, so after being compounded by the first composite mechanism 6, the glue has completely adhered to the front of the second material. When the second material comes out of the first composite mechanism 6, the second material has been coated with glue, and the glue coated on the circular hole of the second material will directly pass through the circular hole and be coated on the first material, and the first material with part of the glue will be separated from the second material and recycled into the first material receiving mechanism 5. A first resistance detection device 9 is set on the left side of the first composite mechanism 6, and the first resistance detection device 9 is fixed on the left bracket 101.

[0060] A small DC power supply (not shown) is provided in the first resistance detection device 9. The DC power supply can be within 12V. One end of the power supply is connected to the first composite active roller 601, and the other end is connected to the first composite driven roller 602. Then a small ohmmeter (not shown) is connected in series between them. The first composite active roller 601, the first composite driven roller 602, the power supply and the ohmmeter form a series connection. Since the first composite active roller 601 is tangent to the coating roller 20, the first composite active roller 601 will have glue on it. The ohmmeter is used to detect the resistance change between the first composite active roller 601 with glue and the first composite driven roller 602.

[0061] When no material passes through the first composite mechanism 6, the pointer of the ohmmeter does not deflect. When the first material and the second material enter the first composite mechanism 6, due to the extra layer of material between the first composite active roller 601 and the first composite driven roller 602, the resistance between the first composite active roller 601 and the first composite driven roller 602 changes, thereby causing the ohmmeter in the first resistance detection device 9 to deflect.

[0062] If only the first material enters the first composite mechanism 6, the ohmmeter deflects, and the deflection index of the ohmmeter is set to A. If only the second material enters the first composite mechanism 6, the deflection index of the ohmmeter is set to B. If the first material and the second material enter the first composite mechanism 6 together, the deflection index of the ohmmeter is set to C. When the equipment starts to operate and the first material and the second material enter the first composite mechanism 6, it can be judged which materials have entered the first composite mechanism 6 for composite according to the deflection index on the ohmmeter. When the index of the ohmmeter is always A, it can be judged that the second material has not entered the first composite mechanism 6 for composite. At this time, the first resistance detection device 9 will send a signal to the controller.

[0063] When the index on the ohmmeter is always B, it can be concluded that the first material has not entered the first compounding mechanism 6 for compounding, and the first resistance detection device 9 will send a signal to the controller. When the index on the ohmmeter is C, it can be determined that the first material and the second material have begun to compound. If the first material partially covers the second material, we can calculate the specific compounding position of the first material and the second material based on the time when the index A on the ohmmeter changes to C or B changes to C. At this time, the first resistance detection device 9 will send a signal to the controller indicating the material offset, and the controller will then control the rotation speed of the first feeding mechanism 2 or the second feeding mechanism 3 to achieve the expected compounding effect of the first material and the second material.

[0064] The first feeding mechanism 2 and the first receiving mechanism 5 are respectively fixed on the crossbeam 103 . The first feeding mechanism 2 and the first receiving mechanism 5 are located at the upper end of the second feeding mechanism 3 and close to the left bracket 101 . The first feeding mechanism 2 is located on the left side of the first receiving mechanism 5 .

[0065] The first receiving mechanism 5 is connected to a reduction motor (not shown in the figure), which drives the first receiving mechanism 5 to operate, thereby bringing out the first material from the first feeding mechanism 2. The first material enters the first compounding mechanism 6 through multiple transition rollers to be compounded with the second material. During the compounding process, the first material is squeezed on the second material, so when the first material and the second material come out of the first compounding mechanism 6, the front of the second material will be coated. Since the second material has round holes, the glue passing through the round holes will stick to the first material. The second material sticks to the glue and continues to run to the subsequent second receiving mechanism 8, and the first material with some glue will be recycled into the first receiving mechanism 5.

[0066] The third feeding mechanism 4 is fixed on the right bracket 102 and is located at the lower right side of the right bracket 102. The second receiving mechanism 8 is fixed on the lower left side of the right bracket 102. The second composite mechanism 7 is fixed in the middle of the right bracket 102 and is located between the third feeding mechanism 4 and the second receiving mechanism 8.

[0067] The second composite mechanism 7 includes: a second composite active roller 701 and a second composite driven roller 702, which are arranged in parallel up and down. The second material with glue comes out of the first composite mechanism 6, and the third material comes out of the third feeding mechanism 4, and they are transported by multiple transition rollers and enter the second composite mechanism 7.

[0068] It should be noted that the second composite active roller 701 is connected to a driving device (not shown in the figure), and the driving device can be a reduction motor or an AC servo motor. The reduction motor drives the second composite active roller 701 to rotate, thereby pulling the second material with glue and the third material to be composited. After the second material with glue and the third material enter the composite mechanism 7, the composite process begins. The second material and the third material with glue are brought into the second composite mechanism 7 under the action of the second composite active roller 701. Since the second material and the third material with glue are in contact with the second composite driven roller 702, relative friction is generated with the second composite driven roller 702, driving the second composite driven roller 702 to operate.

[0069] Under the co-extrusion of the second composite active roller 701 and the second composite driven roller 702, the second material with glue is gradually covered on the third material. After being composited by the second composite mechanism 7, the second material with glue is completely adhered to the third material. When the second material with glue and the third material come out of the second composite mechanism 7, the second material with glue has been composited with the third material. The second material with glue is composited with the third material to form a composite material. A second resistance detection device 10 is provided on the left side of the second composite mechanism 7, and the second resistance detection device 10 is fixed on the right bracket 102.

[0070] A small DC power supply (not shown in the figure) is provided in the second resistance detection device 10. The power supply can be within 12V. One end of the power supply is connected to the second composite active roller 7017, and the other end is connected to the second composite driven roller 702. Then a small ohmmeter (not shown in the figure) is connected in series between them. The second composite active roller 701, the second composite driven roller 702, the power supply and the ohmmeter form a series connection. The ohmmeter is used to detect the resistance change between the second composite active roller 701 and the second composite driven roller 702.

[0071] When no material passes through the second composite mechanism 7, the pointer of the ohmmeter does not deflect. When the second material and the third material with glue enter the second composite mechanism 7, due to the extra layer of material between the second composite active roller 701 and the second composite driven roller 702, the resistance between the second composite active roller 701 and the second composite driven roller 702 changes, thereby causing the ohmmeter in the second resistance detection device 10 to deflect.

[0072] If only the second material with glue enters the second composite mechanism 7, the ohmmeter deflects, and the deflection index of the ohmmeter is set to D. If only the third material enters the second composite mechanism 7, the deflection index of the ohmmeter is set to E. If the second material with glue and the third material enter the second composite mechanism 7 together, the deflection index of the ohmmeter is set to F. When the equipment starts to operate, when the second material and the third material with glue enter the second composite mechanism 7, it can be judged which materials have entered the second composite mechanism 7 for composite according to the deflection index on the ohmmeter. When the index of the ohmmeter is always D, it can be determined that the third material has not entered the second composite mechanism 7 for composite. At this time, the second resistance detection device 10 will send a signal to the controller. When the index of the ohmmeter is always E, it can be concluded that the second material with glue has not entered the second composite mechanism 7 for composite, and the second resistance detection device 10 will send a signal to the controller. When the index on the ohmmeter is F, it can be determined that the second material with glue and the third material have begun to composite. If the third material partially covers the second material with glue, we can calculate the specific composite position of the second material with glue and the third material based on the time it takes for the index D on the ohmmeter to change to F or E to change to F. At this time, the second resistance detection device 10 will send a signal to the controller to indicate the material offset, and the controller will then control the rotation speed of the third feeding mechanism 4 to achieve the expected composite effect of the second material with glue and the third material.

[0073] It is not difficult to find out from the above content that the composite equipment for making porous materials of the present invention is provided with a frame 1, a first feeding mechanism 2, a second feeding mechanism 3, a third feeding mechanism 4, a first receiving mechanism 5, a first composite mechanism 6, a second composite mechanism 7, a second receiving mechanism 8, a first resistance detection device 9, a second resistance detection device 10 and a controller. The frame 1 includes: a crossbeam 103, a left bracket 101 and a right bracket 102. The crossbeam 103 is provided with a first feeding mechanism 2 and a first receiving mechanism 5, the left bracket 101 is provided with a second feeding mechanism 3, a first composite mechanism 6 and a first resistance detection device 9, and the right bracket 102 is provided with a second feeding mechanism 3, a first composite mechanism 6 and a first resistance detection device 9.

[0074] A third feeding mechanism 4, a second receiving mechanism 8, a second compounding mechanism 7 and a second resistance detection device 10 are provided. The first material is added to the first feeding mechanism on the equipment. When the second material with round holes is to be coated with glue, the side of the second material coated with glue is the front side, and the first feeding mechanism releases the first material to be compounded with the back side of the second material with round holes being coated with glue. Since the first material is added to the back side of the material with round holes and the first material covers the back side, the glue will not leak to the back side of the second material with round holes. When the second material with round holes is coated with glue, the first material will be taken back by the first receiving mechanism, and the second material with round holes that has been coated with glue will continue to be transported backward. Adding the first material can prevent glue leakage and prevent glue from sticking to the equipment. And when the second material is square, it can meet the composite requirements and present the required shape. It can ensure the aesthetics of the composite material and prevent the problem of glue leakage. When the material is compounded in the first compounding mechanism 6, the first resistance detection device 9 can detect the compounding status of the material. When the material is compounded in the second compounding mechanism 7, the second resistance detection device 10 can detect the compounding status of the material to detect whether the material is compounded at a preset position. If a deviation occurs, a signal will be sent to the controller to enable the compounding process to proceed smoothly. This not only increases the compounding diversity of the material, but also ensures the compounding progress of the material and improves the compounding efficiency.

[0075] Optionally, in this embodiment, a composite device for making a porous material includes a limit switch 11. The limit switch 11 is fixed on the right bracket 102, and the limit switch 11 is located on the right side of the second material receiving mechanism 8. The limit switch 11 includes: a first sensor (not shown in the figure) and a control switch (not shown in the figure).

[0076] The first sensor may be an infrared sensor, which is used to monitor the position of the composite material collected by the second receiving mechanism 8 from the right bracket 102. Since the second receiving mechanism 8 collects the composite material of the second material and the third material, the diameter of the composite material on the second receiving mechanism 8 will become wider and wider. In order to prevent the composite material from being stuck in the second receiving mechanism 8 due to being too large, the maximum allowable distance between the composite material and the right bracket 102 can be set to the safety range of the infrared sensor. Within the safety range, the second receiving mechanism 8 can continuously collect materials. Once the safety range of the infrared sensor is exceeded, the infrared sensor will send a signal to the controller. The control switch can be a dip switch, a cam switch, a toggle switch and a touch switch. When the first sensor sends a signal to the controller, the controller receives the signal, manually presses the touch switch, and the touch switch sends a signal to the controller, and the controller forces the first feeding mechanism 2, the second feeding mechanism 3 and the third feeding mechanism 4 to stop operating. If it is necessary to resume the operation of the equipment, click the touch switch, and the controller drives the first feeding mechanism 2, the second feeding mechanism 3 and the third feeding mechanism 4 to start running. The limit switch 11 is electrically connected to the controller.

[0077] Optionally, in this embodiment, a composite device for making porous materials includes: a thickness gauge 12. The thickness gauge 12 is fixed on the right bracket 102, and the thickness gauge 12 is located behind the second composite mechanism 7. When the composite material comes out of the second composite mechanism 7, it passes through the thickness gauge 12. The thickness gauge 12 can be a laser thickness gauge 12, an X-ray thickness gauge, and an ultrasonic thickness gauge. The laser thickness gauge 12 uses laser light to irradiate the composite material and then reflect it back to obtain the thickness of the composite material. The allowable thickness of the composite material is set to a predetermined range of the laser thickness gauge 12. When the composite material is too thick and exceeds the predetermined range of the laser thickness gauge 12, the laser thickness gauge 12 will send a signal to the controller. The laser thickness gauge 12 is electrically connected to the controller.

[0078] Optionally, in this embodiment, a composite device for making porous materials includes: a plurality of flattening rollers 13. The plurality of flattening rollers 13 are respectively located on the left bracket, the right bracket 102 and the crossbeam 103. The plurality of flattening rollers 13 are edge flattening rollers, which are arranged at the two edges of the material, with one group arranged on each side, one roller is placed below the material, and the other roller is placed above the material, and the two rollers are arranged parallel to each other. A certain angle is maintained with the vertical direction of the material running. When working, the two rollers are pressed together, and the rollers are driven to rotate by the material, so that a lateral expansion tension force is generated on both sides of the material, thereby achieving the purpose of flattening the material.

[0079] Optionally, in this embodiment, a composite device for making porous materials includes a scraper 14. The scraper is arranged on the left bracket 101, and the scraper is located on the right side of the first composite active roller and abuts against the first composite active roller. After the coating roller dips the paint from the paint box, the paint will be transferred to the first composite active roller through the coating roller. Since the glue is liquid and has strong fluidity, when the glue is transferred to the first composite active roller, it will cause uneven glue thickness. During the rotation of the first composite active roller, the scraper will always abut against the surface of the first composite active roller, and the glue on the first composite active roller will be scraped evenly through the action of the scraper abutting against the first composite active roller. Therefore, when the glue is applied to the second material, it is also even and smooth, so that the material can be of uniform thickness during compounding.

[0080] Optionally, in the present embodiment, a composite device for making a porous material includes a second sensor 15, a third sensor 16 and a fourth sensor 17. The second sensor 15, the third sensor 16 and the fourth sensor 17 may be ultrasonic sensors or infrared sensors, and the second ultrasonic sensor, the third ultrasonic sensor and the fourth ultrasonic sensor are respectively arranged on the cross beam 103. When the second material with glue passes through the cross beam 103, since the cross beam 103 is long, the transportation distance of the second material with glue is long, which will affect the walking path of the second material with glue. According to the width of the second material with glue, three positions are set, at both ends and in the middle of the second material with glue, and the first ultrasonic sensor is set at the second material with glue.

[0081] The second material with glue will pass through the leftmost end, the second ultrasonic sensor is set at the middle position where the second material with glue will pass, and the third ultrasonic sensor is set at the rightmost end where the second material with glue will pass. When the second material with glue passes through the cross beam 103, the first ultrasonic sensor will monitor whether the leftmost position of the second material with glue deviates, the second ultrasonic sensor monitors whether the middle position of the second material with glue deviates, and the third ultrasonic sensor monitors whether the rightmost position of the second material with glue deviates. Assuming that the second material with glue can allow a small error deviation (for example, 1cm) during transportation, the safety range of the first ultrasonic sensor, the second ultrasonic sensor and the third ultrasonic sensor can be set to 1cm. If the deviation distance of the second material with glue exceeds 1cm, the first ultrasonic sensor, the second ultrasonic sensor and the third ultrasonic sensor will send a signal to the controller. The first ultrasonic sensor, the second ultrasonic sensor and the third ultrasonic sensor are electrically connected to the controller.

[0082] Optionally, in this embodiment, a composite device for making porous materials includes a cooling roller 18. The cooling roller 18 is fixed on the right bracket 102, and the cooling roller 18 is located on the left side of the second composite mechanism 7. After the material is composited by the second composite mechanism 7, it is first cooled by the cooling roller 18 before entering the second material receiving mechanism 8. Cooling water or coolant is passed into the cooling roller 18 to cool it. When the composited material passes through the cooling roller 18, the temperature of the material is reduced, and the deformation caused by the shrinkage of the hot material when it is cooled is reduced.

[0083] Optionally, in this embodiment, a composite device for making porous materials includes a drying device 19. The drying device 19 includes an electric heating wire (not shown) and a hair dryer (not shown). The drying device 19 is fixed to the crossbeam 103, and the drying device 19 is located above the right bracket 102. The drying device 19 can dry the material through the electric heating wire and the hair dryer. Before the second material with glue comes out of the first composite mechanism 6 and reaches the drying device 19, the surface of the second material with glue contains a large amount of moisture. When the second material with glue passes through the drying device 19, the electric heating wire is heated, and the hair dryer continuously blows hot air to generate a thermal cycle, which accelerates the volatilization rate of the coating solvent on the surface of the material, and promotes a better bonding effect of the second material with glue when it is composited in the second composite mechanism 7.

[0085] Moreover, the first feature being “above”, “above”, and “above” the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being “below”, “below”, and “below” the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
