Description

Technical Field

[0001] This utility model relates to the technical field of pearl cotton processing equipment, and in particular to a chipping and waste removal machine. Background Technology

[0002] EPE foam, a widely used packaging and filling material, typically needs to be cut into different shapes and specifications according to requirements in practical applications. However, achieving fast, efficient, and reliable cutting in mass production scenarios remains a pressing technical challenge. Traditional manual cutting methods are inefficient and cannot meet the demands of modern production, while existing automated cutting equipment often suffers from insufficient precision, complex operation, or poor adaptability, failing to fully meet the needs for cutting various shapes. Furthermore, waste material from the EPE foam may not be completely separated during the cutting process, leading to difficulties in subsequent processing and further impacting overall production efficiency and product quality. Therefore, developing a device capable of high-precision, high-volume cutting with waste removal capabilities is crucial. This invention aims to provide a chipping and waste removal machine by optimizing the design of the feeding, imprinting, and cutting mechanisms, thereby solving the aforementioned problems and significantly improving the efficiency and reliability of EPE foam processing. Utility Model Content

[0003] The purpose of this invention is to provide a chipper and waste discharge machine to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A chipping and waste removal machine is provided for efficient processing and waste disposal of EPE foam. The machine includes an EPE foam placement assembly, a feeding mechanism, a lifting and pressing mechanism, a moving cutting mechanism, and female and male molds. Specifically, in a second embodiment, the chipping and waste removal machine adds a waste removal function, further improving the quality of the finished product.

[0006] The pearl cotton placement assembly is composed of multiple sheet metal parts, with a through-hole at its bottom. This slot design allows the top block to push the bottom layer of pearl cotton forward as it moves back and forth, thus enabling the pearl cotton to be pushed piece by piece. The pearl cotton placement assembly is used to stack pearl cotton to be processed, providing a stable supply of raw materials for subsequent processing.

[0007] Furthermore, the feeding mechanism includes a translation plate, ejector blocks, a drive motor, a feeding drive shaft, a belt drive pulley, a driven tension pulley, and a feeding control belt. Multiple ejector blocks are arranged at linear intervals on the translation plate, with the height of each ejector block slightly higher than the aluminum strips on the frame, thus smoothly pushing the pearl cotton pieces one by one below the lifting and pressing mechanism. The drive motor drives the feeding drive shaft to rotate via a transmission component, which in turn drives the feeding control belt between the belt drive pulley and the driven tension pulley to translate, realizing the reciprocating motion of the translation plate.

[0008] Specifically, the lifting and pressing mechanism includes a gantry frame, a drive shaft, lifting gears, a lifting motor, a commutator, guide columns, a rack, and a lifting fixing plate. The gantry frame is fixed to the machine frame. Lifting gears are installed at both ends of the drive shaft, and the lifting gears mesh with the rack, which is connected to the lifting fixing plate. A male mold is fixed to the bottom of the lifting fixing plate. The bottom of the male mold has an integrally formed downward-extending contoured protrusion for pressing the pearl cotton partially down to the through hole of the female mold. The lifting motor drives the drive shaft to rotate through the commutator, thereby driving the rack to move up and down, realizing the lifting and lowering operation of the male mold.

[0009] Furthermore, the moving cutting mechanism includes a traveling frame, a chipping drive wheel, a chipping motor, a drive pulley, a transmission component, a traveling motor, a traveling helical gear, and a guide rack. The traveling frame is slidably connected to the machine frame via linear bearings and guide rails, and the blade strip is tightly wrapped around the upper edge of the chipping drive wheel. The chipping motor controls the rotation of the chipping drive wheel via the drive pulley and transmission component, thereby driving the blade strip to move horizontally. The traveling motor meshes with the guide rack via the traveling helical gear, controlling the traveling frame to move back and forth relative to the machine frame, enabling the blade strip to perform horizontal cutting between the female mold and the male mold.

[0010] The female mold is positioned below the male mold and has a through-hole corresponding to the protrusion of the male mold, used to receive a portion of the pearl cotton being pressed down by the male mold. Since the pearl cotton has a certain thickness, only a portion of it needs to be squeezed into the through-hole of the female mold, without the male mold needing to be fully pressed into the through-hole. This design allows the cutting blade to move between the male and female molds and slice the pearl cotton, avoiding interference between the cutting blade and the male mold, and also improving processing efficiency.

[0011] Specifically, in the second embodiment, flat-headed ejector pins are inserted into multiple through holes in the lifting and fixing plate, and the ejector pins are fixed to the lifting and fixing plate by baffles. The ejector pins are used to push out waste material that has not been completely separated from the pearl cotton, ensuring the quality of the finished product.

[0012] The workflow of this utility model includes the following steps: S1, the worker stacks pearl cotton in the pearl cotton placement assembly, and the feeding mechanism pushes the pearl cotton piece by piece to the bottom of the lifting and pressing mechanism through the ejector block and the translation plate; S2, the lifting and pressing mechanism controls the male mold to press down, pressing the pearl cotton partially down to the through hole of the female mold, forming a cotton sheet with the same shape as the through hole of the female mold; S3, the blade in the moving cutting mechanism moves and cuts between the male mold and the female mold, removing multiple cotton sheets of different shapes; S4, in the second embodiment, the ejector pin on the lifting and fixing plate can eject the waste material on the pearl cotton, completing the waste removal operation.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The coordinated operation of the feeding mechanism, lifting and pressing mechanism, and moving cutting mechanism enables large-volume, rapid, and reliable cutting of pearl cotton. The matching design of the male and female molds ensures precise and consistent shapes of the cut cotton sheets. The added ejector pin waste removal function in the second embodiment solves the problem of incomplete separation of waste material from the pearl cotton, improving the quality of the finished product. The modular design of each mechanism facilitates maintenance and replacement, while also enhancing the overall stability and service life of the equipment.

[0015] Specifically, the chipping and waste removal machine achieves efficient processing and precise molding through a specific structural design. For example, the ejector block in the feeding mechanism is slightly higher than the aluminum profile, ensuring that the pearl cotton is pushed smoothly without deviation; the lifting and pressing mechanism achieves precise lifting and lowering of the mold through the meshing of the lifting gear and the rack, ensuring processing accuracy; the moving cutting mechanism achieves the forward and backward movement of the traveling frame through the meshing of the traveling helical gear and the guide rack, enabling the blade belt to precisely cut the pearl cotton.

[0016] Furthermore, in the second embodiment, the ejector pin waste removal function uses a baffle to fix the ejector pin to the lifting plate, ensuring the ejector pin remains stable during lifting. The flat-head design of the ejector pin avoids damage to the surface of the pearl cotton, while effectively ejecting waste material and improving the quality of the finished product.

[0017] In summary, this utility model provides a high-efficiency, precise and reliable chipping and waste removal machine, which is suitable for large-scale processing of pearl cotton and has significant technical advantages and market application value. Attached Figure Description

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0031] A chipping and waste disposal machine is used for the efficient processing and waste disposal of pearl cotton. (In conjunction with attached...) Figure 1 To be continued Figure 7 The following describes in detail the specific embodiments of this utility model. First, the chipper and waste removal machine includes a pearl cotton placement assembly 1, a feeding mechanism 2, a lifting and pressing mechanism 3, a moving cutting mechanism 4, a female mold 5, a male mold 6, and a blade belt 7. The following will explain the working process of the chipper and waste removal machine in conjunction with the structural design and operating principle of each component.

[0032] The core of the chipping and waste removal machine lies in its modular design, which enables rapid processing and precise molding of pearl cotton. (See attached image) Figure 1 As shown, the EPE foam placement assembly 1 is composed of multiple sheet metal parts, with a through-hole at its bottom. This slot design allows the ejector block 19 to push the bottom layer of EPE foam forward as it moves back and forth. The ejector block 19 is slightly higher than the aluminum strip on the frame, ensuring smooth and stable pushing of the EPE foam. Workers can place stacked EPE foam into the EPE foam placement assembly 1, providing a stable supply of raw materials for subsequent processing.

[0033] The design of feeding mechanism 2 enables the sequential feeding of pearl cotton pieces. Combined with the attached... Figure 5 and attached Figure 6 The feeding mechanism 2 includes a translation plate 21, ejector blocks 19, a drive motor 20, a feeding drive shaft 24, a belt drive pulley, a driven tension pulley 22, and a feeding control belt 23. Multiple ejector blocks 19 are arranged at linear intervals on the translation plate 21, and the ejector blocks 19 are connected to the feeding control belt 23 via belt fasteners. The drive motor 20 drives the feeding drive shaft 24 to rotate via a transmission component, which in turn drives the feeding control belt 23 between the belt drive pulley and the driven tension pulley 22 to translate. The translation of the feeding control belt 23 causes the translation plate 21 to move back and forth, thereby pushing the pearl cotton piece by piece to below the lifting and pressing mechanism 3. This design ensures a continuous supply of pearl cotton and avoids the inefficiency problems of manual operation.

[0034] The lifting and pressing mechanism 3 is one of the key components of the chipping and waste removal machine, used to locally press the pearl cotton down to the through hole of the master mold 5. (See attached...) Figure 4The lifting and pressing mechanism 3 includes a gantry frame 13, a drive shaft 12, lifting gears 14, a lifting motor 15, a commutator 16, guide columns 18, a rack 17, and a lifting fixing plate. The gantry frame 13 is fixed on the machine frame. Lifting gears 14 are installed at both ends of the drive shaft 12, and the lifting gears 14 mesh with the rack 17, which is connected to the lifting fixing plate. A male mold 6 is fixed to the bottom of the lifting fixing plate, and the bottom of the male mold 6 has a downwardly extending contoured protrusion integrally formed. The lifting motor 15 drives the drive shaft 12 to rotate through the commutator 16, thereby driving the rack 17 to move up and down, realizing the lifting and lowering operation of the male mold 6. The contoured protrusion of the male mold 6 corresponds to the contoured through hole of the female mold 5. When the male mold 6 is pressed down, since the pearl cotton has a certain thickness, only part of the pearl cotton needs to be squeezed into the through hole of the female mold 5, and the male mold 6 does not need to be fully pressed into the through hole. This design allows the blade 7 to move between the male and female molds and slice the pearl cotton, avoiding interference between the blade 7 and the male mold, and also improving processing efficiency.

[0035] The moving cutting mechanism 4 is responsible for precisely cutting the pearl cotton. (Combined with...) Figure 3 The moving cutting mechanism 4 includes a traveling frame 9, a chipping drive wheel 8, a chipping motor 10, a drive pulley 11, a transmission component, a traveling motor 25, a traveling helical gear 27, and a guide rack 26. The traveling frame 9 is slidably connected to the machine frame via linear bearings and guide rails. The chipping drive wheel 8 has its blade belt 7 tightly wrapped around its upper edge. The chipping motor 10 controls the rotation of the chipping drive wheel 8 via the drive pulley 11 and the transmission component, thereby driving the blade belt 7 to translate. The traveling motor 25 meshes with the guide rack 26 via the traveling helical gear 27, controlling the forward and backward movement of the traveling frame 9 relative to the machine frame. The blade belt 7 can translate and cut between the female mold 5 and the male mold 6, removing multiple cotton pieces of different shapes. This design ensures the efficiency and precision of the cutting process.

[0036] The working process of the chipping and waste removal machine is as follows: S1, the worker stacks pearl cotton in the pearl cotton placement component 1, and the feeding mechanism 2 pushes the pearl cotton piece by piece to the bottom of the lifting and pressing mechanism 3 through the ejector block 19 and the translation plate 21; S2, the lifting and pressing mechanism 3 controls the male mold 6 to press down, pressing the pearl cotton partially down to the through hole of the female mold 5, forming a cotton sheet with the same shape as the through hole of the female mold 5; S3, the blade 7 in the moving cutting mechanism 4 moves and cuts between the male mold 6 and the female mold 5, cutting off multiple cotton sheets of different shapes; S4, in the second embodiment, the ejector pin 29 on the lifting and fixing plate ejects the waste material on the pearl cotton, completing the waste removal operation.

[0037] In the second embodiment, the chipper waste removal machine adds a waste removal function, further improving the quality of the finished product. (See attached diagram.) Figure 7Flat-headed ejector pins 29 are inserted into multiple through holes in the lifting and fixing plate, and the ejector pins 29 are fixed to the lifting and fixing plate by a baffle 28. The ejector pins 29 are used to eject any incompletely separated waste material from the pearl cotton, ensuring the quality of the finished product. The flat-head design of the ejector pins 29 avoids damage to the surface of the pearl cotton while effectively ejecting waste material. This design solves the problem of incomplete separation of waste material from the pearl cotton and improves the quality of the finished product.

[0038] The chipper and waste discharge machine employs a modular design for easy maintenance and replacement. For example, the ejector block 19 in the feeding mechanism 2 is slightly higher than the aluminum profile, ensuring smooth and unbiased feeding of the pearl cotton. The lifting and pressing mechanism 3 achieves precise lifting and lowering of the mold 6 through the meshing of the lifting gear 14 and the rack 17, ensuring processing accuracy. The moving cutting mechanism 4 achieves the forward and backward movement of the traveling frame 9 through the meshing of the traveling helical gear 27 and the guide rack 26, enabling the blade belt 7 to precisely cut the pearl cotton. These designs not only improve the overall stability and service life of the equipment but also reduce maintenance costs.

[0039] The chipping and waste removal machine has a wide range of applications and is suitable for large-scale processing of EPE foam. For example, on packaging material production lines, the chipping and waste removal machine can efficiently complete the cutting and waste removal of EPE foam, meeting the processing needs for different shapes. (See attached image.) Figure 1 To be continued Figure 7 The chipper and waste removal machine achieves efficient processing and precise molding through specific structural design. The feeding mechanism 2 ensures a continuous supply of pearl cotton, the lifting and pressing mechanism 3 achieves precise pressing of the pearl cotton, the moving cutting mechanism 4 completes the efficient cutting of the pearl cotton, and the waste removal function of the ejector pin 29 further improves the quality of the finished product.

[0040] In summary, the chipper and waste removal machine, through its modular design and collaborative operation, achieves high-volume, rapid, and reliable cutting of EPE foam. The cooperative design of the male mold 6 and female mold 5 ensures precise and consistent shapes of the cut cotton flakes. The waste removal function of the ejector pin 29 solves the problem of incomplete separation of waste material from the EPE foam, improving the quality of the finished product. The chipper and waste removal machine has significant technical advantages and market application value, and is suitable for large-scale processing of EPE foam.

[0041] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
