Description

Technical Field

[0001] The utility model relates to the technical field of packaging material processing, in particular to a feeding mechanism. Background Art

[0002] Packaging materials include pearl cotton, cardboard, polyethylene, polyvinyl chloride, etc. Taking pearl cotton as an example, pearl cotton has many advantages such as water-proof and moisture-proof, shockproof, soundproof, heat-insulating, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance and is an ideal packaging material. Most of the existing packaging materials have the limitation of non-plasticity, and many packaging materials need to undergo a series of tedious processing before they can be formed, and the key step requires bonding equipment.

[0003] When the laminating equipment is in use, the package will be conveyed through the feeding mechanism. The package needs to be glued during the conveying process to ensure the subsequent laminating operation of the package. The existing feeding mechanism usually uses a conveyor belt to convey the package, but because the conveyor belt rotates along a closed loop trajectory, the mold cannot be installed on the conveyor belt, and the package can only be placed directly on the conveyor belt; however, with the diversification of the application scenarios of the package, many packages adopt a non-planar structural design. If the package is not supported by the mold, the package cannot be glued and laminated horizontally or smoothly, which limits the use of the laminating equipment. Utility Model Content

[0004] The technical problems to be solved by the utility model are:

[0005] The existing conveying structure cannot be installed with a mold, and cannot provide horizontal and stable support for non-planar packaging, which has limitations in use.

[0006] In order to solve the above technical problems, the utility model provides a feeding mechanism, comprising:

[0007] Scaffolding;

[0008] A feeding assembly, the feeding assembly comprising a bearing platform, a feeding drive, a bearing slider, a bearing slide rail and a mold; the bearing platform is movably connected to the base frame, the feeding drive is connected to the bearing platform to drive the bearing platform to move relative to the base frame; the bearing slide rail is in the shape of an elongated strip, the bearing slider is slidably arranged on the bearing slide rail, one of the bearing slider and the bearing slide rail is connected to the base frame, and the other is connected to the bearing platform; the mold is mounted on the bearing platform; and

[0009] A glue coating component is arranged on a side of the carrying platform away from the base frame, and is used for coating glue on the workpiece on the mold.

[0011] In one of the embodiments, pressure relief surfaces are disposed on both sides of the load-sharing portion; the pressure relief surfaces on both sides are inclined and gradually approach each other in a direction from the stabilizing portion toward the guiding portion.

[0012] In one of the embodiments, the hook blocks are relatively arranged on two sides of the inner wall of the guide groove, the hook blocks on both sides are extended towards each other, and the hook blocks on both sides are respectively pressed against the pressure relief surfaces on both sides.

[0013] In one embodiment, the guide portion is in a cylindrical structure, the guide groove is in an arc-shaped groove, and the guide portion fits against an inner wall of the guide groove.

[0014] In one embodiment, the hook block is hooked on a side of the guide portion close to the load-sharing portion.

[0015] In one embodiment, the stabilizing portion and the carrying platform are both in the shape of a straight plate, and an extension plane where the stabilizing portion is located is parallel to an extension plane where the carrying platform is located.

[0016] In one of the embodiments, the feeding drive component includes a rotating shaft, a feeding motor, a feeding driving wheel, a feeding driven wheel and a feeding belt; the rotating shaft is rotatably connected to the base frame, and the feeding motor is connected to the rotating shaft to drive the rotating shaft to rotate; the feeding driving wheel is installed on the rotating shaft, and the feeding driving wheel rotates with the rotating shaft; the feeding driven wheel is rotatably connected to the base frame, and the feeding belt is sleeved on the outer sides of the feeding driving wheel and the feeding driven wheel, and the feeding belt is connected to the supporting platform.

[0017] In one of the embodiments, there are two load-bearing slide rails, which are arranged opposite to each other on two sides of the load-bearing platform; and at least two load-bearing sliding blocks are slidably disposed on the same load-bearing slide rail.

[0018] In one of the embodiments, the feeder belt is arranged in the same direction as the bearing slide rail, and the feeder belt is set at the middle position of the bearing slide rails on both sides.

[0019] Compared with the prior art, the above-mentioned feeding mechanism has the following beneficial effects:

[0020] The carrying platform is driven to move by the feeding drive to convey the packages. The carrying platform can install and fix the mold, and then the packages can be placed in the mold. The mold supports the packages horizontally and stably on the carrying platform, ensuring that the feeding mechanism can convey non-planar packages horizontally and stably, eliminating the limitations of traditional belt structures on package transportation and improving the adaptability of the feeding mechanism.

[0021] By arranging pressure relief surfaces on both sides of the load-sharing portion, and slanting the pressure relief surfaces on both sides so as to gradually approach each other from the stabilizing portion toward the guiding portion, the hook block is pressed against the pressure relief surface of the load-sharing portion, so that the impact load borne by the bearing platform can be converted into a part of the horizontal component through the inclined setting of the pressure relief surface, thereby reducing the positive pressure between the bearing slider and the bearing slide rail, improving the bearing limit of the bearing platform, and ensuring the reliability of the bearing platform in the subsequent process of bonding the packaging.

[0022] By setting the guide part to be cylindrical and fitting the guide part to the inner wall of the guide groove, the force bearing area between the bearing slider and the bearing rail that bears the positive impact load is increased, the bearing limit of the bearing platform is further increased, and the stability of the bearing platform operation is ensured.

[0039] See also Figures 1 to 5, is a feeding mechanism 100 of an embodiment of the utility model, comprising a base frame 10, a feeding assembly 20 and a glue coating assembly 30. The base frame 10 is used to support the overall feeding mechanism 100. The feeding assembly 20 comprises a bearing platform 21, a feeding drive 22, a bearing slider 23, a bearing slide rail 24 and a mold 25; the bearing platform 21 is movably connected to the base frame 10, and the feeding drive 22 is connected to the bearing platform 21 to drive the bearing platform 21 to move relative to the base frame 10; the bearing slide rail 24 is in a long strip shape, and the bearing slider 23 is slidably arranged on the bearing slide rail 24, one of the bearing slider 23 and the bearing slide rail 24 is connected to the base frame 10, and the other is connected to the bearing platform 21; the mold 25 is installed on the bearing platform 21; the mold 25 is used to place the package to be bonded. The glue coating assembly 30 is arranged on the side of the bearing platform 21 away from the base frame 10, and the glue coating assembly 30 is used to apply glue to the workpiece on the mold 25. The packages are conveyed by setting up a carrying platform 21, and the carrying platform 21 can install and fix the mold 25, so that the packages can be placed in the mold 25, and then the packages with non-planar design can be supported horizontally and stably on the carrying platform 21, thereby eliminating the limitations of the traditional belt conveyor structure and improving the adaptability of the feeding mechanism 100.

[0040] Furthermore, the bottom of the base frame 10 is placed on the ground of the external environment, and the base frame 10 is used to support the installation of other components of the feeding mechanism 100. It can be understood that the user can design the specific structure of the base frame 10 according to actual use requirements. The specific structure of the base frame 10 is not limited here, and it is sufficient to ensure that the entire feeding mechanism 100 can be supported and installed.

[0041] Further, the bearing platform 21 is in the shape of a straight plate, and the bearing platform 21 is extended in the horizontal direction. The bearing platform 21 is slidably arranged on the base frame 10, and the bearing platform 21 moves relative to the base frame 10 to transport the package. The feeding drive 22 drives the bearing platform 21 to move linearly back and forth on the base frame 10. Through the straight plate structure of the bearing platform 21, it is ensured that the mold 25 can be supported and fixed, thereby satisfying the structural basis for horizontal support of non-planar designed packages. It can be understood that the feeding drive 22 is one of a cylinder, a hydraulic cylinder, a gear rack, a screw mechanism, a belt mechanism or a linear motor. The specific structure of the feeding drive 22 is not limited here, and it is sufficient to ensure that the feeding drive 22 can drive the bearing platform 21 to move back and forth relative to the base frame 10. The mold 25 can also be designed according to the shape and size of the actual processed package. The specific structure of the mold 25 is not limited here, and it is sufficient to ensure that the package to be bonded can be supported horizontally and stably.

[0042] Further, the feeding drive member 22 includes a rotating shaft 221, a feeding motor 222, a feeding driving wheel 223, a feeding driven wheel 224 and a feeding belt 225. The rotating shaft 221 is rotatably connected to the base frame 10, and the feeding motor 222 is connected to the rotating shaft 221 to drive the rotating shaft 221 to rotate relative to the base frame 10. The feeding driving wheel 223 is installed on the rotating shaft 221, and the feeding driving wheel 223 is sleeved on the outer side of the rotating shaft 221, and the feeding driving wheel 223 rotates together with the rotating shaft 221. The feeding driven wheel 224 is rotatably connected to the base frame 10, and the feeding driven wheel 224 and the feeding driving wheel 223 are spaced apart along the moving direction of the carrying platform 21. The feeding belt 225 is annular, and is sleeved on the outer sides of the feeding driving wheel 223 and the feeding driven wheel 224. The feeding belt 225 is connected to the bearing platform 21, and the feeding driving wheel 223 drives the feeding belt 225 to rotate together, and the feeding belt 225 drives the bearing platform 21 to move linearly. The advantage of using the feeding belt 225 to drive the bearing platform 21 to move is that the feeding belt 225 is a flexible component, and the bearing platform 21 will generate a moving impact load on the feeding drive 22 due to inertia during the linear movement of the bearing platform 21. The impact load generated by the bearing platform 21 can be effectively absorbed by the flexible deformation of the feeding belt 225, thereby eliminating the impact of the impact load on the feeding drive 22, and improving the reliability and service life of the feeding drive 22.

[0043] Furthermore, the bearing rail 24 is in the shape of an elongated strip, and the bearing rail 24 is extended along the moving direction of the bearing platform 21; the bearing slider 23 is slidably arranged on the bearing rail 24, and the bearing slider 23 and the bearing rail 24 are arranged between the bearing platform 21 and the base frame 10 to guide the movement of the bearing platform 21 and ensure the stability of the movement of the bearing platform 21. It can be understood that one of the bearing rail 24 and the bearing slider 23 is connected to the base frame 10, and the other is connected to the bearing platform 21. The specific connection between the two is not limited here, and it is sufficient to ensure that the relative movement between the bearing platform 21 and the base frame 10 can be guided. In this embodiment, the bearing rail 24 is connected to the base frame 10, and the bearing slider 23 is connected to the bearing platform 21.

[0044] Furthermore, the number of the bearing slide rails 24 is two, and the two bearing slide rails 24 are arranged on both sides of the bearing platform 21; at least two bearing sliders 23 are slidably arranged on the same bearing slide rail 24 to ensure more balanced support for the bearing platform 21 and ensure the stability of the movement of the bearing platform 21. In this embodiment, the bearing platform 21 is in the shape of a rectangular straight plate, and the number of the bearing sliders 23 is four, and the four bearing sliders 23 are respectively arranged at the four corner positions of the bearing platform 21, and the two bearing sliders 23 located on the same side of the bearing platform 21 are slidably arranged on the same bearing slide rail 24. Furthermore, the feed belt 225 is arranged in the same direction as the bearing slide rail 24, and the feed belt 225 is arranged at the middle position of the bearing slide rails 24 on both sides to ensure that the pulling force applied by the feed belt 225 to the bearing platform 21 acts evenly on the bearing slide rails 24 on both sides, avoiding the feed belt 225 from generating torque load on the bearing platform 21, and ensuring the reliability of the use of the bearing platform 21.

[0045] Further, the bearing slide rail 24 includes a stabilizing portion 241, a load-sharing portion 242 and a guiding portion 243. The stabilizing portion 241 is in the shape of a rectangular straight plate, connected to the base frame 10, and the extending plane where the stabilizing portion 241 is located is parallel to the extending plane where the bearing platform 21 is located, and the stabilizing portion 241 is used to stably support the bearing slide rail 24 on the base frame 10. The load-sharing portion 242 extends from the stabilizing portion 241 toward the bearing platform 21, and the load-sharing portion 242 is arranged between the stabilizing portion 241 and the guiding portion 243. The guiding portion 243 is arranged on a side of the load-sharing portion 242 away from the stabilizing portion 241, and the guiding portion 243 is embedded in the bearing slider 23. In this embodiment, a guiding groove 231 is arranged on the bearing slider 23; the guiding groove 231 is arranged in the shape of a groove on a side of the bearing slider 23 close to the bearing slide rail 24, and the guiding portion 243 is embedded in the guiding groove 231. A hook block 235 is provided in the guide groove 231; the hook block 235 is abutted against the load-sharing portion 242. By abutting the guide portion 243 against the inner wall of the guide groove 231 and the hook block 235 against the load-sharing portion 242, the joint area between the bearing slide rail 24 and the bearing slider 23 is increased, thereby improving the pressure-bearing performance between the bearing slide rail 24 and the bearing slider 23, thereby increasing the load limit of the bearing platform 21 and ensuring the stability of the operation of the bearing platform 21. The main reason why the belt conveyor structure is mainly used in the existing structure is that the belt structure has a certain flexibility and can withstand the impact load of the package during the stamping and bonding process; the bearing platform 21 adopts a rigid structure that can withstand the impact load. During the test, it was found that the guide components are easily damaged. Therefore, the present application improves the design of the bearing slide rail 24 and the bearing slider 23. The guide portion 243 abuts against the inner wall of the guide groove 231, and the hook block 235 abuts against the load-sharing portion 242, thereby improving the performance of the bearing slide rail 24 and the bearing slider 23 in bearing the impact load, thereby ensuring the feasibility and reliability of the bearing platform 21 in conveying the package.

[0046] Furthermore, pressure relief surfaces 245 are provided on both sides of the load-sharing portion 242. The pressure relief surfaces 245 on both sides are inclined and gradually approach each other in the direction from the stabilizing portion 241 to the guide portion 243. The hook block 235 is relatively arranged on both sides of the inner wall of the guide groove 231, and the hook blocks 235 on both sides extend toward each other, and the hook blocks 235 on both sides are respectively pressed against the pressure relief surfaces 245 on both sides. The pressure relief surface 245 makes the hook block 235 contact the load-sharing portion 242 in an inclined posture, and the positive impact force borne by the bearing platform 21 will generate a part of the horizontal component force through the inclined pressure relief surface 245, and the positive pressure between the bearing slide rail 24 and the bearing slider 23 is reduced by the force component, so as to further improve the performance of the bearing slide rail 24 and the bearing slider 23 in bearing the impact load, and improve the reliability of the bearing platform 21 in conveying the package.

[0047] Furthermore, the guide portion 243 is arranged in a cylindrical structure, and the guide groove 231 is in an arc-shaped groove shape. The guide portion 243 is fitted with the inner wall of the guide groove 231. By fitting the guide portion 243 with the inner wall of the guide groove 231 in an arc-shaped structure, compared with the existing planar fitting structure, the arc-shaped structure can increase the force bearing area between the bearing slide rail 24 and the bearing slider 23 that withstands the positive pressure, further improve the performance of the bearing slide rail 24 and the bearing slider 23 in bearing impact loads, and thereby improve the reliability of the bearing platform 21 for transporting packages.

[0048] Furthermore, the gluing assembly 30 is mounted above the carrying platform 21. When the carrying platform 21 conveys the package and passes through the gluing assembly 30, the gluing assembly 30 will apply glue to the upper surface of the package on the mold 25 to ensure the subsequent fitting operation of the package. Since the upper surface of the package needs to be level during the gluing process, so that the gluing can be uniform, the package can be supported by the mold 25 to ensure that the lower surface of the package is uneven, and the upper surface can be made level by the support of the mold 25, thereby achieving a uniform upper surface gluing operation for the package with an uneven lower surface. It can be understood that the specific structure of the gluing assembly 30 is not limited here, and it is sufficient to ensure that the gluing assembly 30 can apply glue to the package in the mold 25. In this embodiment, the gluing assembly 30 applies glue to the structure of rolling the passing package by a rubber roller with glue attached.

[0049] In summary, the embodiment of the utility model provides a feeding mechanism 100, which has the following beneficial effects:

[0050] The carrying platform 21 is driven to move by the feeding drive 22 to convey the packages. The carrying platform 21 can install and fix the mold 25, and then the packages can be placed in the mold 25. The mold 25 can support the packages horizontally and stably on the carrying platform 21, ensuring that the loading mechanism 100 can horizontally and stably convey the packages with non-planar designs, eliminating the limitations of the traditional belt structure on the conveyance of packages, and improving the adaptability of the loading mechanism 100.

[0051] By setting pressure relief surfaces 245 on both sides of the load-sharing portion 242, and tilting the pressure relief surfaces 245 on both sides so as to gradually approach each other from the stabilizing portion 241 toward the guiding portion 243, the hook block 235 is pressed against the pressure relief surface 245 of the load-sharing portion 242, so that the impact load borne by the supporting platform 21 can be converted into a part of the horizontal component through the tilted setting of the pressure relief surface 245, thereby reducing the positive pressure between the supporting slider 23 and the supporting slide rail 24, thereby increasing the load limit of the supporting platform 21, and ensuring the reliability of the supporting platform 21 in the subsequent process of bonding the packaging.

[0052] By setting the guide part 243 to a cylindrical shape and fitting the guide part 243 to the inner wall of the guide groove 231, the force bearing area between the bearing slider 23 and the bearing rail 24 that withstands the positive impact load is increased, further improving the bearing limit of the bearing platform 21 and ensuring the stability of the operation of the bearing platform 21.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
