Description

Technical Field

[0001] The invention relates to the technical field of packaging bag production, in particular to a high-speed dry-type compounding device. Background Art

[0002] High-speed dry laminating machine is a kind of equipment used for high-speed production of composite materials. It is mainly used to laminate two or more different types of materials at high speed, usually plastic film, paper, aluminum foil and other materials. It usually includes the following main components: feeding system, coating system, drying system, laminating system, cooling system and receiving system. Due to its high efficiency, high degree of automation and fast production speed, it is widely used in food packaging, pharmaceutical packaging, building materials, electronic products and other fields.

[0003] In the related art, the Chinese patent publication number is CN214000878U, and the name is a high-speed dry compound machine, including a base, a feed port and a discharge port are arranged on the base, a material combining frame is arranged at one end of the base close to the feed port, a pressing device is arranged on the base, and the pressing device includes a first pressing roller and a second pressing roller, a first driving source is arranged on the base, a scraper is arranged on the base, and a driving assembly is arranged on the base. The material to be compounded passes through the material combining frame for coating with glue, and then drives the composite material coated with glue to pass through the first pressing roller and the second pressing roller, the first driving source drives the first pressing roller to rotate, and then drives the composite material to move, and the composite material is pressed by the first pressing roller and the second pressing roller, and in this process, the scraper abuts against the surface of the second pressing roller to scrape off the glue contaminated on the second pressing roller. Although the above-mentioned device can scrape off the glue on the second pressure roller, the following problems still exist: since the scraper slides through the receiving groove, the end of the scraper abuts against the surface of the second pressure roller, and the scraper is inclined, when the scraper scrapes off the glue on the second pressure roller, although some of the glue will drip directly into the receiving groove, some of the glue will flow along the upper surface of the scraper and then flow into the receiving groove and the installation groove, so that the components in the receiving groove and the installation groove (such as screw rods, springs, etc.) will be contaminated with glue. Especially after working for a long time, the open ends of the receiving groove and the installation groove are easily blocked by glue, thereby affecting the normal operation of the equipment. Therefore, it is necessary to frequently disassemble and clean the installation groove and the receiving groove, which increases the labor intensity of the staff. Summary of the invention

[0039] Please refer to Figure 1-9 As shown, this embodiment provides a high-speed dry compounding device, including a base 24, an extrusion compounding mechanism, a glue scraping mechanism and a glue collecting tank 23;

[0040] The extrusion compounding mechanism is disposed on the base 24 and is used for extruding and compounding the composite material coated with glue;

[0041] The scraping mechanism is arranged on one side of the extrusion and compounding mechanism;

[0042] The glue collecting tank 23 is disposed on the base 24 and is located directly below the glue scraping mechanism;

[0043] The scraper mechanism includes a mounting frame, a screw adjustment assembly and two scraper assemblies;

[0044] The mounting frame is mounted on the base 24;

[0045] The screw adjustment assembly includes a bidirectional screw 16 and two movable seats 9. The bidirectional screw 16 is rotatably mounted on the mounting frame and has a first threaded portion and a second threaded portion with opposite rotation directions. The two movable seats 9 are respectively threadedly connected to the first threaded portion and the second threaded portion.

[0046] The two scraper assemblies are symmetrically arranged on the bidirectional screw 16, and each scraper assembly includes a connecting piece and a scraper 2; one end of the connecting piece is installed on the movable seat 9, and the other end extends out of the movable seat 9 and is connected to the scraper 2; a guide groove 3 is arranged on the side of the scraper 2, and the two ends of the guide groove 3 respectively pass through the top surface and the bottom surface of the scraper 2, and the guide groove 3 is used to guide the glue on the scraping part to fall directly into the glue collecting groove 23.

[0047] On the basis of the above structure, during the movement of the material, the two extrusion composite rollers 1 of the extrusion composite mechanism rotate towards each other under the action of the driving force, applying specific pressure and heat to the material. In this way, the glue is quickly solidified under the action of heat and pressure, thereby achieving a tight composite of the material. By rotating the bidirectional screw 16, the two moving seats 9 can be driven to move relative to or towards each other in the lateral direction, thereby adjusting the gap between the two scrapers 2 and the two sides of the composite material. The scraping part of the scraper 2 is close to the roller surface to scrape off the excess glue. Since the two ends of the guide groove 3 respectively penetrate the top and bottom surfaces of the scraper 2, the glue flowing laterally along the scraper 2 will enter the guide groove 3. After being guided by the guide groove 3, the glue will directly fall from the bottom opening of the guide groove 3 to the glue collection groove 23 below, and the glue flowing laterally along the scraping part will directly fall into the glue collection groove 23 below. In this way, it can be ensured that all the scraped glue can directly fall into the glue collection groove 23 below, effectively preventing the glue from entering the inside of the mounting frame, and keeping the equipment clean and operating normally. During the scraping process, the excess glue is scraped off by the scraper 2 and falls directly into the glue collection groove 23 along the guide groove 3. The staff can regularly clean the glue collection groove 23 and process or recycle the collected glue. In this way, the present invention ensures that the scraped glue can directly fall into the glue collecting groove 23 below through the cooperation of the movable seat 9, the connecting piece, the scraper 2 and the guide groove 3, effectively preventing the glue from entering the interior of the mounting frame, maintaining the cleanliness and normal operation of the equipment, and eliminating the need to frequently disassemble and clean the mounting frame and the bidirectional screw 16, thereby reducing the workload of the staff.

[0048] In a preferred embodiment of the present invention, a conveying device is provided on the base 24 on one side of the extrusion composite mechanism, and a feeding device is provided on the base 24 on the other side of the extrusion composite mechanism; the extrusion composite mechanism includes two upper and lower symmetrical extrusion composite rollers 1 and a fixed frame 26 symmetrically arranged on the base 24, the two extrusion composite rollers 1 are arranged between the two fixed frames 26, and a first electric telescopic rod 25 is installed between the end of the upper extrusion composite roller 1 and the fixed frame 26 by screws, and a drive motor 27 is installed at one end of the lower extrusion composite roller 1, and the drive motor 27 is installed on the fixed frame 26 on one side by screws.

[0049] On the basis of the above structure, the conveying device is responsible for smoothly conveying the materials to be compounded to the extrusion compounding mechanism for processing. The main function of the feeding device is to feed the materials to be compounded into the extrusion compounding mechanism in a predetermined order and manner. The setting of the second electric telescopic rod 20 can adjust the position of the upper extrusion compounding roller 1 according to the use requirements, so as to conveniently adjust the distance between the upper and lower extrusion compounding rollers 1 to adapt to materials of different thicknesses and materials. A drive motor 27 is installed at one end of the lower extrusion compounding roller 1, and the drive motor 27 is installed on a fixed frame 26 on one side by screws. The drive motor 27 provides rotational power for the lower extrusion compounding roller 1, so that it can cooperate with the upper extrusion compounding roller 1 to perform compounding work.

[0050] In a preferred embodiment of the present invention, guide rails 28 are respectively provided on both sides of the glue collecting groove 23, and the guide rails 28 are slidably connected to limit blocks 29, which are installed on the inner side of the fixing frame 26, and the limit blocks 29 are provided with connecting grooves 30 adapted to the guide rails 28.

[0051] In this embodiment, the limit block 29 and the fixing frame 26 are an integrated structure, and the receiving box and the guide rail 28 are an integrated structure. During the scraping process of the scraper 2, the glue slides down from the upper end of the scraper 2, passes through the bottom of the scraper 2, and flows into the receiving box. When the glue flows horizontally on the scraper 2, the glue flows to the position of the guide groove 3, and then flows down along the guide groove 3 to the receiving box, thereby preventing the glue from flowing to the structure other than the scraper 2, which causes cumbersome cleaning. When the receiving box needs to be cleaned, it is pulled out, the guide rail 28 is separated from the connecting groove 30 on the limit block 29, and the receiving box can be removed for cleaning.

[0052] In a preferred embodiment of the present invention, the mounting frame includes two vertical support plates 21, and a transverse rotating frame 18 rotatably mounted between the two vertical support plates 21, and also includes a rotation driving mechanism, which is connected to the transverse rotating frame 18, and the rotation driving mechanism is used to drive the transverse rotating frame 18 to rotate, so as to drive the scraper 2 to rotate to a preset angle.

[0053] On the basis of the above structure, the function of the rotary drive mechanism is to drive the lateral rotating frame 18 to rotate, thereby driving the scraper 2 installed on the rotating frame to rotate to a preset angle. This design allows the angle of the scraper 2 to be adjusted as needed to adapt to different working scenarios and composite material requirements. By adjusting the angle of the scraper 2, the effect of scraping glue can be better controlled. For example, in some cases, it may be necessary to adjust the scraper 2 to a more inclined angle in order to scrape off the glue more effectively; in other cases, it may be necessary to adjust the scraper 2 to a gentler angle to avoid unnecessary damage to the composite material.

[0054] In a preferred embodiment of the present invention, the bidirectional screw rod 16 is installed on the transverse rotating frame 18 through a bearing, and a rotating block 22 is installed at one end of the bidirectional screw rod 16; the transverse rotating frame 18 is also provided with a guide rod 17 parallel to the bidirectional screw rod 16, and the two movable seats 9 are respectively connected to the guide rod 17.

[0055] On the basis of the above structure, when the rotating block 22 is rotated, the bidirectional screw 16 will rotate accordingly. Since the bidirectional screw 16 has a first threaded portion and a second threaded portion with opposite rotation directions, the two movable seats 9 will move relatively close to one side or relatively away from one side under the limiting guidance of the guide rod 17. This design ensures the precise adjustment of the position of the scraper 2. According to the width of the aluminum foil bag raw material, the operator can adjust the position of the two scrapers 2 by rotating the rotating block 22 so that they match the edges of the aluminum foil bag raw material. In this way, when the aluminum foil bag raw material passes through the scraper 2, the excess glue will be effectively scraped off without contaminating the material or equipment. This design combines the precise adjustment capability of the bidirectional screw 16 and the stable guiding function of the guide rod 17, so that the position of the scraper 2 can be adjusted conveniently and accurately.

[0056] In a preferred embodiment of the present invention, the rotation drive mechanism includes a connecting rod 19 and a second electric telescopic rod 20, one end of the connecting rod 19 is connected to the lateral rotating frame 18, and the other end is hinged to the output shaft of the second electric telescopic rod 20, and the other end of the second electric telescopic rod 20 is rotatably mounted on the base 24.

[0057] On the basis of the above structure, when the angle of the scraper 2 needs to be adjusted, the second electric telescopic rod 20 is controlled to start working. The output shaft of the second electric telescopic rod 20 extends or retracts, and the rotational power is transmitted to the transverse rotating frame 18 through the connecting rod 19. The transverse rotating frame 18 starts to rotate under the action of the rotational power, driving the scraper 2 to rotate to a preset angle. During the rotation process, the articulated mode of the connecting rod 19 and the rotatable installation mode of the second electric telescopic rod 20 ensure the smoothness and accuracy of the rotation. After the adjustment is completed, the second electric telescopic rod 20 stops working, and the scraper 2 remains at the preset angle to continue to perform the scraping task. The present invention realizes the stable rotation drive of the transverse rotating frame 18 and the precise adjustment of the angle of the scraper 2 through the cooperation of the connecting rod 19 and the second electric telescopic rod 20, thereby improving the versatility, flexibility and production efficiency of the equipment.

[0058] In a preferred embodiment of the present invention, elastic blocks 10 adapted to the moving seat 9 are symmetrically arranged on both sides of the connecting member, and an extrusion block 11 adapted to the elastic blocks 10 is installed on the moving seat 9;

[0059] The scraper assembly also includes a push plate 12 arranged inside the movable seat 9 and adapted to the connecting piece. A sliding frame 13 is installed on the other side of the push plate 12. A push spring 14 is arranged on the side of the push plate 12 close to the sliding frame 13. The extrusion block 11 squeezes the elastic card block 10, so that the push spring 14 drives the push plate 12 to push the connecting piece to the outside of the movable seat 9.

[0060] On the basis of the above structure, when the scraper assembly needs to be installed, the connector is inserted into the movable seat 9, and the extrusion block 11 squeezes the elastic clamping block 10, causing it to be elastically deformed and clamped on the movable seat 9. The push spring 14 always pushes the push plate 12 to the outside of the movable seat 9, and the push plate 12 pushes the connector to keep it in close contact with the movable seat 9. During the scraping process, the scraper assembly moves in the lateral direction with the movable seat 9, and the push plate 12 assembly and the clamping structure jointly ensure the stability and reliability of the scraper assembly. When the scraper assembly needs to be disassembled, it is only necessary to loosen the extrusion block 11 from the elastic clamping block 10 to remove the connector from the movable seat 9. The clamping structure and the push plate 12 assembly of the present invention realize the stable installation and reliable movement of the scraper assembly on the movable seat 9 through precise structural design, improve the uniformity and effectiveness of scraping, and thus improve product quality and production efficiency.

[0061] In a preferred embodiment of the present invention, the connecting member includes a connecting plate 4 and a mounting plate 5 which is slidably connected thereto up and down, the connecting plate 4 is mounted on the outward end of the scraper 2, a connecting spring 6 is installed in an internal array of the mounting plate 5 near one end of the scraper 2, and the connecting plate 4 is mounted on the connecting spring 6.

[0062] On the basis of the above structure, during the process of scraping glue, the scraper 2 is subjected to the pressure of the glue on the extruded composite roller 1, which will transmit the impact force to the connecting piece. The connecting springs 6 are arranged in an array inside the mounting plate 5, providing a stable support for the connecting plate 4 and allowing the connecting plate 4 to undergo a certain degree of elastic deformation when subjected to external force. When the impact force on the scraper 2 exceeds the elastic limit of the connecting spring 6, the connecting spring 6 will undergo elastic deformation, thereby absorbing part of the impact force and protecting the scraper 2 and the connecting piece from damage. At the same time, the up and down sliding connection between the connecting plate 4 and the mounting plate 5 also allows the scraper 2 to undergo a certain degree of displacement when subjected to impact force, further protecting the scraper 2 and the connecting piece.

[0063] In a preferred embodiment of the present invention, two first guide bars 7 are respectively installed on both sides of the mounting plate 5 , the first guide bars 7 are connected to the second guide bars 8 , and the second guide bars 8 are arranged on the inner side wall of the moving seat 9 .

[0064] On the basis of the above structure, the first guide bar 7 is connected to the second guide bar 8 by a precise connection method. The second guide bar 8 is firmly set on the inner side wall of the moving seat 9, providing a stable guide track for the scraper assembly. The design of the second guide bar 8 takes into account the fit and fixing method with the inner side wall of the moving seat 9 to ensure that it will not loosen or deform during use. The design of this guide connection structure enables the scraper assembly to slide smoothly on the moving seat 9 while maintaining a precise position. It can also withstand the lateral force generated by the scraper 2 during the scraping process to ensure the stability of the scraper 2 and the uniformity of the scraping.

[0065] In a preferred embodiment of the present invention, the movable seat 9 includes a connecting portion and a sliding portion installed on the side away from the extrusion composite roller 1, the connecting portion is sleeved on the outside of one end of the mounting plate 5, and the second guide bar 8 is installed on the inner side wall of the connecting portion.

[0066] On the basis of the above structure, the connecting part is designed to be sleeved on the outside of one end of the mounting plate 5. This design ensures the close fit between the connecting part and the mounting plate 5, and prevents the scraper assembly from shaking or falling off during the scraping process. At the same time, a second guide bar 8 is installed on the inner side wall of the connecting part, and the second guide bar 8 cooperates with the first guide bar 7 on the mounting plate 5 to provide a stable guide track for the scraper assembly, ensuring the stability and accuracy of the scraper assembly during movement.

[0067] In a preferred embodiment of the present invention, the elastic card block 10 is installed on the outside of the mounting plate 5, the extrusion block 11 is installed on the outside of the connecting part, and a card slot 15 adapted to the elastic card block 10 is opened on the outer wall of the connecting part, the inner side of the extrusion block 11 extends into the card slot 15, the push plate 12 and the push spring 14 are both arranged inside the connecting part, and the sliding frame 13 extends to the outside of the connecting part.

[0068] On the basis of the above structure, the elastic block 10 is installed on the outside of the mounting plate 5, and is designed to be clamped with the connecting part of the moving seat 9. The extrusion block 11 is installed on the outside of the connecting part, corresponding to the elastic block 10. A slot 15 adapted to the elastic block 10 is provided on the outer wall of the connecting part, and the slot 15 is used to accommodate the elastic block 10 and ensure that it is firmly clamped on the moving seat 9. The inner side of the extrusion block 11 extends into the slot 15. When the extrusion block 11 is subjected to external force, it will squeeze the elastic block 10, causing it to deform elastically and firmly clamped in the slot 15. The push plate 12 is arranged inside the connecting part, and is designed to push the mounting plate 5 and the scraper assembly thereon. The push spring 14 is also installed inside the connecting part, and it provides a thrust so that the push plate 12 can always push the mounting plate 5 to the outside of the moving seat 9. The sliding frame 13 extends to the outside of the connecting part, and it provides a stable support for the push plate 12 and allows the push plate 12 to move within a certain range. These designs together realize the stable installation and reliable movement of the scraper assembly on the moving seat 9. The clamping structure ensures that the scraper assembly will not shake or fall off during the scraping process, and the push plate 12 assembly ensures the close contact between the scraper assembly and the moving seat 9, improving the uniformity and effectiveness of scraping.

[0069] Working principle of the present invention:

[0070] Equipment adjustment: By rotating the rotating block 22, under the limiting and guiding action of the guide rod 17, the positions of the two moving seats 9 can be adjusted, and then the spacing between the two scrapers 2 can be adjusted to adapt to aluminum foil bag raw materials of different widths. The second electric telescopic rod 20 drives the horizontal rotating frame 18 to rotate through the connecting rod 19 to adjust the inclination angle of the scraper 2 to adapt to the radius of the extrusion composite roller 1.

[0071] Production process: The feeding device conveys the raw material of the aluminum foil bag to the space between the two extrusion laminating rollers 1 for extrusion lamination. The scraper 2 is responsible for removing the glue overflowing from the edge of the raw material. The overflowing glue slides down from the upper end of the scraper 2 and flows to the glue collecting tank 23 through the bottom of the scraper 2. When the glue flows to the guide groove 3, it will flow down along the guide groove 3 to the glue collecting tank 23 to prevent the glue from contaminating other structures.

[0072] Equipment maintenance: When it is necessary to disassemble the scraper 2, the connecting plate 4 and the mounting plate 5, press the extrusion blocks 11 on both sides at the same time. The extrusion blocks 11 squeeze the elastic block 10 in the slot 15 to separate it from the slot 15. The push spring 14 is reset, and the push plate 12 pushes the mounting plate 5 outward. The first guide bar 7 and the second guide bar 8 slide in contact, and the mounting plate 5 and the connecting plate 4 thereon and the scraper 2 can be disassembled. When cleaning the glue collection tank 23, pull it outward, separate the guide rail 28 from the connecting slot 30 on the limit block 29, and then the glue collection tank 23 can be disassembled for cleaning.
