Description

Technical Field

[0001] This utility model belongs to the technical field of EPE cotton block adhesive applicator, and in particular relates to an EPE cotton block double-line adhesive applicator. Background Technology

[0002] In the fields of packaging materials and cushioning materials, EPE (expandable polyethylene) cotton blocks are widely used due to their excellent cushioning, heat insulation and chemical resistance properties. In the processing of EPE cotton blocks, adhesive application is an important step. By attaching adhesive strips to EPE cotton blocks, the connection between cotton blocks or the fixation with other components can be achieved. As a device that can simultaneously apply adhesive to both sides of EPE cotton blocks, the adhesive application accuracy directly affects the quality and performance of subsequent products.

[0003] Currently, existing EPE cotton block double-line adhesive applicators typically rely on simple conveyor devices to move the cotton blocks during the adhesive application process. However, due to the inherent elasticity and softness of EPE cotton blocks, they are susceptible to uneven friction from the conveyor belt and equipment vibration during transport, leading to misalignment. Once the EPE cotton block shifts, the adhesive strip will not adhere accurately, potentially resulting in issues such as the strip deviating from the intended area or asymmetry between the two sides, severely impacting the adhesive application quality and product consistency. Therefore, we propose a new EPE cotton block double-line adhesive applicator. Utility Model Content

[0004] The purpose of this invention is to provide a double-line adhesive applicator for EPE cotton blocks to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an EPE cotton block double-line adhesive applicator, comprising:

[0006] A fixed frame is provided, with a conveyor belt inside. A double-line adhesive applicator is fixedly installed on the top of the fixed frame. Baffles are fixedly installed on the top of the fixed frame and on both sides of the conveyor belt. A rectangular groove is opened on one side of the baffle, and several rollers are rotatably installed in the rectangular groove. Two U-shaped frames are fixedly installed on the fixed frame and above the two baffles. Several mounting blocks are fixedly installed on the opposite sides of the two U-shaped frames. Several limiting plates are provided between the two U-shaped frames. A rotating groove is opened at the bottom of the limiting plate, and several rollers are rotatably installed in the rotating groove. Two round rods are fixedly installed on the top of the limiting plate. The top of the round rods passes through the corresponding mounting blocks. A spring is sleeved on the round rod and between the limiting plate and the mounting block.

[0007] A limiting component is located on a fixed frame and is used to limit the EPE cotton block.

[0008] In this technical solution, during use, the conveyor belt can transport the EPE cotton block. When the top of the EPE cotton block contacts several rollers, the EPE cotton block will squeeze the rollers upward. The upward movement of the rollers will drive the limiting plate upward, which in turn will drive the two round rods upward. At the same time, the upward movement of the limiting plate will compress the two springs, causing them to contract. Under the rebound force of the two springs, the two springs will squeeze the limiting plate downward, ensuring that the bottom of the rollers remains against the EPE cotton block, thus limiting the EPE cotton block at the top of the conveyor belt. At this time, under the action of friction, the EPE cotton block continues to move, causing the rollers to rotate, ensuring that the EPE cotton block is limited and does not deviate during movement, thus avoiding affecting the accuracy of the adhesive application.

[0009] When the EPE cotton block moves below the limiting component, the limiting component can further limit the EPE cotton block to ensure that the EPE cotton block does not shift.

[0010] In the above technical solution, the limiting component further includes:

[0011] Two rectangular plates are fixedly installed on both sides of a fixed frame, and both rectangular plates are located on one side of two U-shaped frames. A fixed rod is fixedly installed between the two rectangular plates. Several rotating blocks are provided on the fixed rod. A movable groove is opened at the bottom of each rotating block. A rotating rod is rotatably installed in the movable groove. A limit rod is fixedly installed on one side of the rotating rod. A lower pressure roller is rotatably installed on the limit rod. A limit post is fixedly installed at the top of the movable groove. A spring is sleeved on the limit post. A mounting plate is provided on one side of each rotating block. Two hexagon socket head cap screws are threaded onto the mounting plate. One end of each hexagon socket head cap screw extends into the rotating block.

[0012] In this technical solution, when the EPE cotton block moves below several pressure rollers, the EPE cotton block will squeeze the pressure rollers to rotate upward. The pressure rollers will drive one end of the rotating rod to rotate upward and squeeze the second spring to contract. Under the action of the rebound force of the second spring, the second spring will squeeze one end of the rotating rod to rotate downward. One end of the rotating rod will drive the pressure roller to rotate downward, so that the bottom of the pressure roller can always be pressed against the EPE cotton block, thereby further limiting the position of the EPE cotton block and ensuring that the EPE cotton block will not deviate.

[0013] When it is necessary to adjust the downward pressure of the lower roller, the operator can use an Allen wrench to loosen the two Allen bolts. At this time, the two Allen bolts can release the limiting position of the rotating block and the mounting plate. The operator can adjust the downward pressure of the lower roller by rotating the rotating block and the mounting plate. When the downward pressure of the lower roller is adjusted to a suitable level, the two Allen bolts are tightened again to ensure that the operator can easily adjust the downward pressure of the lower roller and ensure that the lower roller can be adapted to EPE cotton blocks of different thicknesses.

[0014] In the above technical solution, furthermore, the two ends of the second spring are tightly welded to the top of the movable groove and the rotating rod, respectively, and one end of the internal hexagon bolt is threadedly connected to the rotating block.

[0015] In this technical solution, the structure of the second spring is ensured to be stable, and one end of the internal hexagonal bolt can rotate into the rotating block.

[0016] In the above technical solution, the rotating rod is inclined, and the mounting plate and the rotating block are located on both sides of the fixed rod.

[0017] In this technical solution, the structural stability of the rotating rod is ensured, as are the structural stability of the mounting plate and the rotating block.

[0018] In the above technical solution, further, the plurality of rollers one are linearly and equally spaced, and the plurality of rollers two are linearly and equally spaced.

[0019] In this technical solution, it is ensured that the force on several rollers is uniform and that the force on several rollers is uniform.

[0020] In the above technical solution, furthermore, the two ends of the spring are tightly welded to the top of the mounting block and the limiting plate, respectively, and the round rod is slidably connected to the mounting block.

[0021] In this technical solution, the structure of spring one is ensured to be stable, and the round rod can slide normally within the mounting block.

[0022] In the above technical solution, furthermore, the plurality of the limiting plates are linearly and equally spaced.

[0023] In this technical solution, it is ensured that the force on several limiting plates is uniform.

[0024] In this technical solution, the limiting plate is equipped with a sensor for detecting the distance between the adhesive application position and the edge of the EPE cotton block, which generally ensures that the distance between the adhesive application position and both sides of the EPE cotton block is within a preset distance range.

[0025] In this technical solution, the dual-line adhesive applicator is movably and adjustablely mounted on a fixed frame. Two dual-line adhesive applicators are connected by an adjusting rod, which is adjusted by rotating a handwheel. By rotating the handwheel, the two dual-line adhesive applicators are controlled to move closer or further apart, thereby adapting to the application of EPE cotton blocks of different widths. The dual-line adhesive applicator is equipped with an adhesive applicator wheel, the position of which can be moved up and down to adapt to the application of EPE cotton blocks of different thicknesses.

[0026] The beneficial effects of this utility model are:

[0027] This EPE cotton block double-line adhesive applicator, through the coordinated action of roller two, a limiting plate, a round rod, a spring, and other limiting components, ensures that the EPE cotton block is positioned correctly during movement, preventing deviation and ensuring accurate adhesive application. During normal transport, the double-line adhesive applicator automatically applies adhesive to the upper surface of the EPE cotton block. Sensors on the limiting plate control the distance between the adhesive application position and the sides of the EPE cotton block within a preset range, ensuring proper cutting and preventing the adhesive from extending beyond the outer edge of the EPE cotton block. A handwheel allows adjustment of the position between the double-line adhesive applicators to accommodate EPE cotton blocks of different widths. The vertical position of the adhesive application rollers is also adjustable to accommodate EPE cotton blocks of varying thicknesses, making it highly versatile. Attached Figure Description

[0040] Example 1:

[0041] Please see Figure 1 - Figure 5 As shown, this embodiment provides an EPE cotton block double-line adhesive applicator, including:

[0042] A fixed frame 1 is provided, and a conveyor belt 2 is provided inside the fixed frame 1. A double-line adhesive applicator 3 is fixedly installed on the top of the fixed frame 1. Baffles 4 are fixedly installed on the top of the fixed frame 1 and on both sides of the conveyor belt 2. A rectangular groove 5 is opened on one side of the baffle 4. Several rollers 6 are rotatably installed in the rectangular groove 5. Two U-shaped frames 7 are fixedly installed on the fixed frame 1 and above the two baffles 4. Several mounting blocks 8 are fixedly installed on the opposite side of the two U-shaped frames 7. Several limiting plates 11 are provided between the two U-shaped frames 7. A rotating groove 12 is opened at the bottom of the limiting plate 11. Several rollers 13 are rotatably installed in the rotating groove 12. Two round rods 9 are fixedly installed on the top of the limiting plate 11. The top of the round rods 9 passes through the corresponding mounting blocks 8. A spring 10 is sleeved on the round rods 9 and between the limiting plate 11 and the mounting blocks 8.

[0043] A limiting component is located on the fixing frame 1 and is used to limit the EPE cotton block.

[0044] In use, the conveyor belt 2 transports the EPE cotton block. When the top of the EPE cotton block contacts the rollers 13, the EPE cotton block will squeeze the rollers 13 and move them upward. The upward movement of the rollers 13 will drive the limiting plate 11 to move upward. The upward movement of the limiting plate 11 will drive the two round rods 9 to move upward. At the same time, the upward movement of the limiting plate 11 will squeeze the two springs 10 to contract. Under the action of the rebound force of the two springs 10, the two springs 10 will squeeze the limiting plate 11 to move downward, so that the bottom of the rollers 13 can always be pressed against the EPE cotton block, thereby limiting the EPE cotton block at the top of the conveyor belt 2. At this time, under the action of friction, the EPE cotton block continues to move and will drive the rollers 13 to rotate, ensuring that the EPE cotton block can be limited and that the EPE cotton block will not deviate during the movement, so as to avoid affecting the accuracy of the adhesive application.

[0045] When the EPE cotton block moves below the limiting component, the limiting component can further limit the EPE cotton block to ensure that the EPE cotton block does not shift.

[0046] Example 2:

[0047] This embodiment provides an EPE cotton block double-line adhesive applicator, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a limiting component:

[0048] Two rectangular plates 14 are fixedly installed on both sides of the fixed frame 1, and both rectangular plates 14 are located on one side of the two U-shaped frames 7. A fixed rod 15 is fixedly installed between the two rectangular plates 14. Several rotating blocks 16 are provided on the fixed rod 15. A movable groove 17 is opened at the bottom of the rotating block 16. A rotating rod 18 is rotatably installed in the movable groove 17. A limit rod 19 is fixedly installed on one side of the rotating rod 18. A lower pressure roller 20 is rotatably installed on the limit rod 19. A limit post 23 is fixedly installed at the top of the movable groove 17. A spring 24 is sleeved on the limit post 23. A mounting plate 21 is provided on one side of the rotating block 16. Two hexagon socket head cap screws 22 are threaded on the mounting plate 21. One end of each hexagon socket head cap screw 22 extends into the rotating block 16.

[0049] When the EPE cotton block moves below several pressure rollers 20, the EPE cotton block will squeeze the pressure rollers 20 to rotate upward. The pressure rollers 20 will drive one end of the rotating rod 18 to rotate upward and squeeze the second spring 24 to contract. Under the action of the rebound force of the second spring 24, the second spring 24 will squeeze one end of the rotating rod 18 to rotate downward. One end of the rotating rod 18 will drive the pressure rollers 20 to rotate downward, so that the bottom of the pressure rollers 20 can always be pressed against the EPE cotton block, thereby further limiting the position of the EPE cotton block and ensuring that the EPE cotton block will not deviate.

[0050] When it is necessary to adjust the downward pressure of the lower pressure roller 20, the operator can use an Allen wrench to loosen the two Allen bolts 22. At this time, the two Allen bolts 22 can release the limiting position of the rotating block 16 and the mounting plate 21. The operator can adjust the downward pressure of the lower pressure roller 20 by rotating the angle of the rotating block 16 and the mounting plate 21. When the downward pressure of the lower pressure roller 20 is adjusted to a suitable level, the two Allen bolts 22 are tightened to ensure that the operator can easily adjust the downward pressure of the lower pressure roller 20 and ensure that the lower pressure roller 20 can be adapted to EPE cotton blocks of different thicknesses.

[0051] Example 3:

[0052] This embodiment provides an EPE cotton block double-line adhesive applicator. In addition to the technical solutions of the above embodiments, it also has the following technical features: the two ends of the spring 24 are tightly welded to the top of the movable groove 17 and the rotating rod 18, respectively; one end of the internal hex bolt 22 is threadedly connected to the rotating block 16.

[0053] Among these measures, the structure of spring 24 is kept stable, and one end of the internal hex bolt 22 is rotated to enter the rotating block 16.

[0054] Example 4:

[0055] This embodiment provides an EPE cotton block double-line adhesive applicator. In addition to the technical solutions of the above embodiments, it also has the following technical features: the rotating rod 18 has an inclined structure, and the mounting plate 21 and the rotating block 16 are located on both sides of the fixed rod 15.

[0056] This ensures the structural stability of the rotating rod 18, as well as the structural stability of the mounting plate 21 and the rotating block 16.

[0057] Example 5:

[0058] This embodiment provides an EPE cotton block double-line adhesive applicator, which, in addition to the technical solution of the above embodiment, also has the following technical features: a plurality of rollers 6 are linearly and equally spaced, and a plurality of rollers 13 are linearly and equally spaced.

[0059] In this process, it is ensured that the force on several rollers 6 is uniform, and that the force on several rollers 13 is uniform.

[0060] Example 6:

[0061] This embodiment provides an EPE cotton block double-line adhesive applicator. In addition to the technical solutions of the above embodiments, it also has the following technical features: the two ends of the spring-10 are tightly welded to the top of the mounting block 8 and the limiting plate 11, respectively, and the round rod 9 is slidably connected to the mounting block 8.

[0062] Among these measures, ensuring the structural stability of spring 10 and guaranteeing that the round rod 9 can slide normally within the mounting block 8 is crucial.

[0063] Example 7:

[0064] This embodiment provides an EPE cotton block double-line adhesive applicator, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a plurality of limiting plates 11 are linearly and equally spaced.

[0065] This ensures that the force on several limiting plates 11 is uniform.

[0066] Example 8:

[0067] In this technical solution, the limiting plate 11 is equipped with a sensor for detecting the distance between the adhesive application position and the edge of the EPE cotton block. Generally, it is ensured that the distance between the adhesive application position and both sides of the EPE cotton block is within a preset distance range. In this embodiment, the preferred preset distance is between 2-3mm. Through the sensor on the limiting plate, and by ensuring that the adhesive is properly cut during application, the adhesive will not be applied outside the EPE cotton block.

[0068] In this technical solution, the double-line adhesive applicator 3 is movably and adjustablely mounted on the fixed frame 1. Two double-line adhesive applicators 3 are connected by an adjusting rod 25, which is adjusted by rotating a handwheel. By rotating the handwheel, the two double-line adhesive applicators 3 are controlled to move closer or further apart, thereby adapting to the application of EPE cotton blocks of different widths. The double-line adhesive applicator 3 is equipped with an adhesive applicator wheel 26, the position of which can be moved up and down to adapt to the application of EPE cotton blocks of different thicknesses. The position between the double-line adhesive applicators 3 can be adjusted by the handwheel to adapt to the application of EPE cotton blocks of different widths. The up and down position of the adhesive applicator wheel 26 is adjustable, thus meeting the application of EPE cotton blocks of different thicknesses, and has high versatility.

[0069] Working principle: During use, the conveyor belt 2 can transport the EPE cotton block. When the top of the EPE cotton block contacts the rollers 13, the EPE cotton block will squeeze the rollers 13 to move upward. The upward movement of the rollers 13 will drive the limiting plate 11 to move upward. The upward movement of the limiting plate 11 will drive the two round rods 9 to move upward. At the same time, the upward movement of the limiting plate 11 will squeeze the two springs 10 to contract. Under the action of the rebound force of the two springs 10, the two springs 10 will squeeze the limiting plate 11 to move downward, so that the bottom of the rollers 13 can always be pressed against the EPE cotton block, thereby limiting the EPE cotton block at the top of the conveyor belt 2. At this time, under the action of friction, the EPE cotton block continues to move and will drive the rollers 13 to rotate, ensuring that the EPE cotton block can be limited and that the EPE cotton block will not deviate during the movement, so as to avoid affecting the accuracy of the adhesive application.

[0070] When the EPE cotton block moves below several pressure rollers 20, the EPE cotton block will squeeze the pressure rollers 20 to rotate upward. The pressure rollers 20 will drive one end of the rotating rod 18 to rotate upward and squeeze the second spring 24 to contract. Under the action of the rebound force of the second spring 24, the second spring 24 will squeeze one end of the rotating rod 18 to rotate downward. One end of the rotating rod 18 will drive the pressure rollers 20 to rotate downward, so that the bottom of the pressure rollers 20 can always be pressed against the EPE cotton block, thereby further limiting the position of the EPE cotton block and ensuring that the EPE cotton block will not deviate.

[0071] When it is necessary to adjust the downward pressure of the lower pressure roller 20, the operator can use an Allen wrench to loosen the two Allen bolts 22. At this time, the two Allen bolts 22 can release the limit on the rotating block 16 and the mounting plate 21. The operator can adjust the downward pressure of the lower pressure roller 20 by rotating the rotating block 16 and the mounting plate 21. When the downward pressure of the lower pressure roller 20 is adjusted to a suitable level, the two Allen bolts 22 are tightened to ensure that the operator can easily adjust the downward pressure of the lower pressure roller 20 and ensure that the lower pressure roller 20 can adapt to EPE cotton blocks of different thicknesses. When the EPE cotton block runs to the bottom of the double-line adhesive applicator 3, the double-line adhesive applicator 3 applies double-line adhesive to the upper surface of the EPE cotton block and automatically cuts the tape. During the adhesive application process, the EPE cotton block is conveyed normally.

[0072] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
