Description

Technical Field

[0001] This utility model relates to the field of cap-making machine technology, and in particular to a feeding and discharging device for a cap-making machine. Background Technology

[0002] Currently, bottle caps are common plastic products in beverage packaging production, usually made using plastic melt extrusion technology. As beverage companies gradually increase their output, users are placing increasingly higher demands on the production efficiency and stability of bottle caps.

[0003] Existing cap-making machines mainly include an extruder, a feeding / discharging turntable, and a forming turntable. The feeding / discharging turntable has a scraping structure on its underside, and the forming turntable has multiple circumferentially distributed molds. The specific compression molding process is as follows: The extruder first melts plastic granules into a rubber compound. The molten rubber compound is extruded at a constant speed through the extruder's outlet. The feeding / discharging turntable, driven by the scraping structure, scrapes away the rubber compound at the outlet and feeds it into the molds on the forming turntable. At the junction of the feeding / discharging turntable and the forming turntable, a measured amount of rubber compound is fed into the rotating mold. After leaving the junction, the mold quickly closes, and the molten rubber compound is then compressed and cooled to form the bottle cap. The mold reopens, ejecting the bottle cap and transferring it to the feeding / discharging turntable. Finally, the bottle cap is removed via the feeding / discharging turntable.

[0004] Chinese patent application CN102596530B discloses an apparatus for conveying objects, comprising: a conveyor turntable rotatable about a rotation axis, adapted to remove caps from a molding turntable and convey the caps to a conveyor belt; the conveyor turntable includes a plurality of conveyor arms connected to the turntable for movement relative to a support element. Each conveyor arm is in a more retracted position as it approaches the molding turntable, and in a more extended position relative to the rotation axis as it approaches the conveyor belt. The conveyor turntable of this apparatus is equivalent to an infeed / outfeed turntable, capable of transferring bottle caps made by the molding turntable to the conveyor belt.

[0005] However, with the increasing production speed of existing cap-making machines, the retraction and extension movements of the conveyor arms are not precise during the high-speed rotation of the feed turntable. This makes it difficult to ensure that the feed turntable can quickly complete the cap receiving and discharging actions while ensuring the stability of cap-making production. Utility Model Content

[0006] The technical problem this invention aims to solve is: during the high-speed rotation of the feed turntable, it is difficult to ensure that the feed turntable can quickly complete the cap receiving and discharging actions while ensuring the stability of cap production.

[0007] To solve the above-mentioned technical problems, this utility model provides a technical solution for the feeding and discharging device of a cap-making machine: The feeding and discharging device of the cap-making machine includes a frame, a feeding and discharging turntable, a guide groove structure, a baffle, and multiple feeding components. The feeding and discharging turntable is rotatably mounted on the upper part of the frame. The guide groove structure is spaced apart on the upper side of the feeding and discharging turntable, and the guide groove structure is fixedly connected to the frame. The feed turntable is provided with multiple slide rails and multiple sliders at circumferential intervals. Each slide rail extends radially along the feed turntable, and the slider is guided and engaged with the slide rail. The material feeding component is connected to the slider. The guide groove structure is a rotary structure and is guided and engaged with the material feeding component. The feed turntable has a feed area and a discharge area. In the feed area, the distance between the guide groove structure and the center line of the feed turntable is d1; in the discharge area, the distance between the guide groove structure and the center line of the feed turntable is d2, and d1 < d2. The baffle is located on the outside of the feed turntable and is fixedly connected to the frame; from the feed area to the discharge area, the baffle is gradually arranged radially away from the feed turntable so as to push the bottle cap away from the feed turntable by the feeding member.

[0008] Furthermore, the feeding and discharging device also includes a receiving plate, which is located outside the feeding and discharging turntable and arranged from the feeding area to the discharging area. The baffle is disposed on the upper side of the receiving plate, and the upper surface of the receiving plate is flush with or lower than the upper surface of the feeding and discharging turntable.

[0009] Furthermore, the guide groove structure is a cam-shaped guide groove, the opening of the cam-shaped guide groove is located close to the feed turntable, and the feeding member is provided with a convex shaft on the side away from the feed turntable, the convex shaft being movably disposed within the cam-shaped guide groove.

[0010] Furthermore, the length of the slide rail is L, the radial dimension of the bottle cap is D, and L≥D.

[0011] Furthermore, the feeding component is a fork, and the end of the fork away from the slider is provided with a receiving groove, which is used to limit the bottle cap; the opening of the receiving groove gradually increases in the direction away from the slider.

[0012] Furthermore, the baffle includes an arc-shaped segment and a straight segment. The arc-shaped segment surrounds the outer part of the feed turntable from the feed area to the discharge area, and the straight segment is located in the discharge area and is smoothly connected to the arc-shaped segment.

[0013] Furthermore, the feeding and discharging device also includes a conveying mechanism, which is located in the discharge area and is arranged along the tangential direction of the feeding and discharging turntable corresponding to the discharge area, with the straight segment located on the outside of the conveying mechanism.

[0014] Furthermore, the conveying mechanism is a conveyor belt, and the surface of the conveyor belt is provided with an adsorption part, which adsorbs and cooperates with the bottle cap.

[0015] Furthermore, the feeding and discharging device also includes a first bracket and a second bracket. The guide trough structure and the baffle are respectively fixedly installed on the frame through the first bracket, and the conveyor belt is fixedly installed on the frame through the second bracket.

[0016] Compared with the prior art, the feeding and discharging device of the cap-making machine of this utility model has the following advantages: The feeding and discharging device of the cap-making machine adopts a design of frame, feeding and discharging turntable, guide groove structure, baffle and multiple material feeding components. The feeding and discharging turntable is rotatably installed on the upper part of the frame. The guide groove structure is spaced on the upper side of the feeding and discharging turntable and fixed to the frame. The feeding and discharging turntable is circumferentially spaced with multiple slide rails and multiple sliders. Each slide rail extends radially along the feeding and discharging turntable, and the slider is guided and cooperated with the slide rail. The material feeding components are fixedly connected to the slider. The guide groove structure is a rotary structure and is guided and cooperated with the material feeding components.

[0017] The rotary guide groove structure guides the movement of the feeding component, while the slide rail and slider provide precise radial guidance, ensuring the smoothness of the feeding component's synchronous opening or retraction during rotation. The feed turntable has a feeding area and a discharging area. During operation, the feed turntable generates a circumferential driving force on the feeding component as it moves from the feeding area to the discharging area. The feeding component is simultaneously guided by the guide groove structure, and the spacing d1 between the feeding areas is smaller than the spacing d2 between the discharging areas, causing the feeding component to undergo radial displacement relative to the feed turntable. This means the feeding component has a motion curve that gradually moves away from the feed turntable circumferentially, allowing the bottle cap to be gradually pushed away from the feed turntable.

[0018] Because the distance d1 between the guide channel structure and the center line of the turntable is small, the guide channel structure can guide the feeding component to move closer to the center. The linear velocity at this point is even lower, allowing the feeding component to accurately catch the bottle caps and transfer them to the infeed / outfeed turntable, ensuring the stability of bottle cap capture. Furthermore, the baffle is located on the outside of the infeed / outfeed turntable and is fixedly connected to the frame. From the feeding area to the discharge area, the baffle gradually moves radially away from the infeed / outfeed turntable.

[0019] As the feeding component moves outward in the discharge zone, it pushes the bottle cap against the baffle, which guides the cap smoothly away from the feed turntable. This gradual movement of the baffle ensures a progressive push-out action during discharge, reducing impact and collision. At high speeds, the slide rails, sliders, guide channels, and baffles provide precise guidance, allowing the bottle cap to move smoothly and accurately along a predetermined path. This ensures the feed turntable can quickly complete the cap receiving and discharging actions, while maintaining the stability of cap production. Attached Figure Description

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] like Figures 1 to 5 As shown, an embodiment of the present invention provides a feeding and discharging device for a cap-making machine, comprising a frame 1, a feeding and discharging turntable 2, a guide groove structure 3, a baffle 4, and multiple feeding components 5. The feeding and discharging turntable 2 is rotatably mounted on the upper part of the frame 1. The guide groove structure 3 is spaced apart on the upper side of the feeding and discharging turntable 2 and is fixedly connected to the frame 1. The feeding and discharging turntable 2 is circumferentially spaced with multiple slide rails 52 and multiple sliders 50. Each slide rail 52 extends radially along the feeding and discharging turntable 2, and the sliders 50 are guided and cooperate with the slide rails 52. The feeding components 5 are fixedly connected to the sliders 50. The slide rails 52 and sliders 50 provide precise radial guidance for the feeding components 5. The guide groove structure 3 is a rotary structure and is guided and cooperates with the feeding components 5.

[0026] The feed turntable 2 has a feed area 21 and a discharge area 22. In the feed area 21, the distance between the guide groove structure 3 and the center line of the feed turntable 2 is d1; in the discharge area 22, the distance between the guide groove structure 3 and the center line of the feed turntable 2 is d2, and d1 < d2. The baffle 4 is located on the outside of the feed turntable 2 and is fixedly connected to the frame 1. From the feed area 21 to the discharge area 22, the baffle 4 is gradually moved radially away from the feed turntable 2 so as to push the bottle cap 7 away from the feed turntable 2 by the pusher 5.

[0027] The feeding and discharging device of this cap-making machine adopts a design consisting of a frame 1, a feeding and discharging turntable 2, a guide groove structure 3, a baffle 4, and multiple feeding components 5. The feeding and discharging turntable 2 is rotatably mounted on the upper part of the frame 1. The guide groove structure 3 is spaced apart on the upper side of the feeding and discharging turntable 2 and fixed to the frame 1. The feeding and discharging turntable 2 is circumferentially spaced with multiple slide rails 52 and multiple sliders 50. The feeding components 5 are fixedly connected to the sliders 50. The guide groove structure 3 is a rotary structure and guides the feeding components 5. The rotary guide groove structure 3 guides the movement of the feeding components 5, and the slide rails 52 and sliders 50 provide precise radial guidance for the feeding components 5, ensuring the smoothness of the synchronous opening or retracting action of the feeding components 5 during rotation.

[0028] The feed turntable 2 has a feed area 21 and a discharge area 22. During operation, the feed turntable 2 generates a circumferential driving force on the feeding component 5 during the movement from the feed area 21 to the discharge area 22. The feeding component 5 is also guided by the guide groove structure 3. The spacing d1 of the feed area 21 is smaller than the spacing d2 of the discharge area 22, causing the feeding component 5 to undergo radial displacement relative to the feed turntable 2. That is, the feeding component 5 has a movement curve that gradually moves away from the feed turntable 2 in the circumferential direction. The bottle cap 7 can be gradually pushed away from the feed turntable 2 by the feeding component 5.

[0029] Because the distance d1 between the guide groove structure 3 and the center line of the turntable is small, the guide groove structure 3 can guide the feeding component 5 to move closer to the center. The linear velocity at this point is even smaller, allowing the feeding component 5 to accurately catch the bottle cap 7 and transfer it to the infeed / outfeed turntable 2, ensuring the stability of capturing the bottle cap 7. Furthermore, the baffle 4 is located on the outside of the infeed / outfeed turntable 2 and is fixedly connected to the frame 1. From the feeding area 21 to the discharge area 22, the baffle 4 is gradually moved radially away from the infeed / outfeed turntable 2.

[0030] As the feeding component 5 moves outward in the discharge zone 22, it pushes the bottle cap 7 against the baffle 4. The baffle 4 guides the bottle cap 7 smoothly away from the feed turntable 2. This gradual movement of the baffle 4 ensures a gradual ejection of the bottle cap 7 during discharge, reducing impact and collision. At high speed, the slide rail 52, slider 50, guide groove structure 3, and baffle 4 provide precise guidance, allowing the bottle cap 7 to move smoothly and accurately along a predetermined path. This ensures that the feed turntable 2 can quickly complete the cap receiving and discharging actions, while maintaining the stability of cap production.

[0031] In this embodiment, the feeding and discharging device further includes a receiving plate 6, which is located outside the feeding and discharging turntable 2 and arranged from the feeding area 21 to the discharging area 22. A baffle 4 is disposed on the upper side of the receiving plate 6, and the upper surface of the receiving plate 6 is flush with or lower than the upper surface of the feeding and discharging turntable 2. The receiving plate 6 provides an auxiliary platform at the interval between the feeding and discharging turntable 2 and the baffle 4, so that the bottle cap 7 can fall smoothly onto the receiving plate 6 after leaving the feeding and discharging turntable 2, preventing the bottle cap 7 from falling accidentally and ensuring the stability of the bottle cap 7 discharging.

[0032] As a further preferred embodiment, the guide groove structure 3 is a cam-shaped guide groove. The opening of the cam-shaped guide groove is located close to the feed / discharge turntable 2. The feeding component 5 has a convex shaft 51 on the side away from the feed / discharge turntable 2, and the convex shaft 51 is movably disposed within the cam-shaped guide groove. The cam-shaped guide groove has the characteristic of a smooth curve transition, which reduces the vibration of the feeding component 5 during high-speed rotation. The convex shaft 51 and the guide groove structure 3 provide guiding cooperation, reliably limiting the movement path of the feeding component 5 and avoiding problems such as shaking or even falling off the feeding component 5.

[0033] Among them, such as Figure 5As shown, the length of the slide rail 52 is L, and the radial dimension of the bottle cap 7 is D, and L≥D. The length L of the slide rail 52 is greater than or equal to the radial dimension D of the bottle cap 7, which ensures that the feeding component 5 is completely retracted into the feeding and discharging turntable 2 in the feeding area 21, and can effectively push the bottle cap 7 outward in the discharging area 22.

[0034] It should be noted that the feeding component 5 is a fork, and the end of the fork away from the slider 50 is provided with a receiving groove 53, which is used to limit the bottle cap 7. The opening of the receiving groove 53 gradually increases in the direction away from the slider 50. The fork cooperates with the baffle 4 to reliably limit the bottle cap 7, preventing the bottle cap 7 from falling off during high-speed rotation. Moreover, the gradually increasing opening of the receiving groove 53 reduces the interference at the end of the fork, ensuring that the bottle cap 7 can be smoothly inserted and pushed away.

[0035] In this embodiment, as Figure 4 As shown, the baffle 4 includes an arc-shaped segment 41 and a straight segment 42. The arc-shaped segment 41 surrounds the outer part of the feed turntable 2 from the feed area 21 to the discharge area 22. The straight segment 42 is located in the discharge area 22 and is smoothly connected to the arc-shaped segment 41. The baffle 4 adopts a two-section design of arc-shaped segment 41 and straight segment 42. The arc-shaped segment 41 matches the outer contour of the guide channel structure 3 to ensure the construction of a bottle cap movement channel with a consistent width. The straight segment 42 is smoothly connected to the arc-shaped segment 41 to ensure the stability of the bottle cap 7 discharge process.

[0036] It should be noted that the feeding and discharging device also includes a conveying mechanism 8, which is located in the discharge area 22 and is arranged along the tangential direction of the feeding and discharging turntable 2 corresponding to the discharge area 22. The straight section 42 is located on the outside of the conveying mechanism 8. The conveying mechanism 8 is a conveyor belt, and the surface of the conveyor belt is provided with an adsorption part 80, which adsorbs and cooperates with the bottle cap 7. The straight section 42 of the baffle 4 can counteract the centrifugal force when the bottle cap 7 is discharged, ensuring that the discharged bottle cap 7 is smoothly transferred to the conveying mechanism 8. The design of the adsorption part 80 in the conveying mechanism 8 further ensures the reliability of conveying the bottle cap 7 in a straight direction.

[0037] In addition, such as Figure 1 As shown, the feeding and discharging device also includes a first support 11 and a second support 12. The guide trough structure 3 and the baffle 4 are fixedly installed on the frame 1 via the first support 11, and the conveyor belt is fixedly installed on the frame 1 via the second support 12. The first support 11, fixed to the frame 1 and avoiding the feeding and discharging turntable 2, provides a top mounting base for the guide trough structure 3, the baffle 4, and the receiving plate 6, thus avoiding installation interference problems for the feeding and discharging turntable 2, the guide trough structure 3, the baffle 4, and the receiving plate 6.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
