Description

Technical Field

[0001] This disclosure pertains to the field of casting processing and feeding, and specifically relates to a continuous manufacturing feeding device. Background Technology

[0002] In the continuous manufacturing process of castings, the feeding device needs to frequently handle workpieces containing cooling media or paint powder. In the prior art, the bottom surface of the castings is often uneven due to residual powder adhesion, which affects the quality of subsequent processing. Traditional solutions mostly rely on external power sources (such as electric vacuum cleaners or pneumatic cleaning), which not only consumes a lot of energy, but also has a complex equipment structure and high maintenance costs. Furthermore, since the bottom surface of the casting is in contact with the support plate, if the cleaning component is kept on until the casting is removed from the support plate, it is easy to waste energy, and prolonged air blowing can easily lead to uneven drying of the coating. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a continuous manufacturing feeding device that solves the problem of energy waste caused by the long-term contact between the support plate and the bottom surface of the casting during the feeding process, which makes it difficult for directional airflow to penetrate effectively.

[0004] The objective of this disclosure can be achieved through the following technical solutions:

[0005] A continuous manufacturing feeding device includes: a support plate, a sealed chamber, and a guide assembly;

[0006] A rubber ring is fixed around the lower edge of the support plate, and a transport platform is provided at the bottom of the rubber ring. The lower end face of the support plate, the rubber ring, and the transport platform form a sealed cavity, and several sets of through holes are provided through the inner side of the support plate.

[0007] A guide assembly is fixed to the lower end face of the support plate;

[0008] When the casting is placed on the upper surface of the support plate, the weight of the casting drives the support plate to move down and compress the support spring. At this time, the volume of the sealed chamber shrinks and generates positive pressure airflow. When the casting is removed, the support spring releases elastic potential energy, causing the support plate to move up. The volume of the sealed chamber expands and forms a negative pressure gradient, which generates directional adsorption airflow through the through-hole array.

[0009] In some disclosures, the guide assembly includes a lead screw, a lead screw nut, and a rotating component. The lead screw is vertically fixed to the lower end face of the support plate, and a lead screw nut that mates with the lead screw is connected to the outer side of the lead screw. The lead screw nut is rotatably connected to the transport table via the rotating component.

[0010] In some disclosures, a fan is coaxially fixedly connected to the outer side of the female connector.

[0011] In some disclosures, the rotating component includes a convex ring and a bearing, and both the upper and lower ends of the fan are coaxially fixed with convex rings, with the outer side of the convex rings being fitted with bearings with clearance.

[0012] In some disclosures, a limiting ring is fixed to the upper surface of the transport platform, and the bottom surface of the convex ring is in contact with the inner wall of the bottom side of the limiting ring.

[0013] In some disclosures, a support frame is fixed to the upper middle part of the transport platform, and a ventilation opening is provided at the upper end of the support frame, and the height of the support frame is higher than the height of the fan.

[0014] In some disclosures, the upper end of the support plate is fixed with a plurality of rectangular strip-shaped protrusions.

[0015] In some disclosures, a sealing strip is fixed at the connection between the rubber ring, the support plate, and the transport platform.

[0016] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0017] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;

[0018] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0019] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.

[0020] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0021] The beneficial effects of this disclosure are:

[0022] 1. The volume of the sealed chamber is changed by gravity driven by the casting, and positive / negative pressure airflow is automatically generated by the mechanical structure. No external energy input is required, which significantly reduces energy consumption and operating costs.

[0023] 2. The fan in the guide assembly moves in both directions with the lead screw, forming a dual airflow path of directional adsorption and reverse blowing, achieving the dual effect of removing loose powder and peeling off stubborn residue, thus improving the cleanliness.

[0031] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0032] Based on the concept of this application, combined with Figures 1 to 5 This document describes an embodiment of a continuous manufacturing feeding device. Specifically, the continuous manufacturing feeding device is constructed as a split structure, comprising three components: a support plate, a sealed chamber, and a guide assembly. The sealed chamber's volume changes are driven by the gravity of the casting, and positive / negative pressure airflow is automatically generated using a mechanical structure. This eliminates the need for external energy input, facilitating the cleaning of the casting's bottom surface at the moment of separation and contact with the support plate, thereby reducing energy waste.

[0033] Please refer to Figures 1 to 5 A continuous manufacturing feeding device includes: a support plate 1, a sealed chamber 4, and a guide assembly 6;

[0034] A rubber ring 2 is fixed around the lower edge of the support plate 1, and a transport platform 3 is provided at the bottom of the rubber ring 2. The lower end face of the support plate 1, the rubber ring 2, and the transport platform 3 form a sealed cavity 4, and a number of through holes 101 are provided through the inner side of the support plate 1.

[0035] The lower end face of the support plate 1 is fixed with a guide component 6;

[0036] When the casting is placed on the upper surface of the support plate 1, the gravity of the casting drives the support plate 1 to move down and compress the support spring 5. At this time, the volume of the sealed chamber 4 shrinks and generates positive pressure airflow. When the casting is removed, the support spring 5 releases elastic potential energy to move the support plate 1 up, and the volume of the sealed chamber 4 expands to form a negative pressure gradient, which generates directional adsorption airflow through the array of through holes 101.

[0037] When the casting is placed on the upper end of the support plate 1, the casting's own weight drives the support plate 1 downwards, simultaneously compressing the support spring 5 on the outside of the screw 61. When the coating is completed and the casting detaches from the support, the pressure of the casting on the support spring 5 decreases, releasing the elastic potential energy stored in the support spring 5. This causes the storage space inside the sealed chamber 4 to expand. During the expansion of the sealed chamber 4, air from the upper end of the outer support plate 1 enters the sealed chamber 4 through the through hole 101. During the airflow, the powder adsorbed on the bottom surface of the casting is adsorbed by negative pressure, removing excess powder from the casting and reducing the adsorption of powdery coating on the bottom surface of the casting. This device drives the contents of the sealed chamber 4 by gravity. The change in volume, combined with the reset of the support spring 5, increases the volume within the sealed chamber 4, generating a negative pressure adsorption effect. This automatically removes residual powder from the bottom surface during the demolding process of the casting. Its innovation lies in constructing a mechanical system that links the processing steps with the cleaning function. A purely mechanical structure is used to achieve directional peeling of the powder coating. The peeled powder coating is carried by the airflow through the through-holes 101 and collected into the sealed chamber 4, which helps reduce outward diffusion. Simultaneously, if the bottom area of ​​the casting increases, the contact area between the bottom surface and the powder coating increases. This increased bottom surface area also increases the area covering the through-holes 101, resulting in a larger adsorption area and thus improved adsorption effect for larger castings. As the bottom area of ​​the casting increases, the projected area covering the array of through-holes 101 increases synchronously. The negative pressure gradient of the exposed area of ​​the through-holes 101 is positively correlated with the contact area of ​​the workpiece, resulting in increased adsorption force. This structural feature allows the device to automatically match the powder peeling efficiency of large-area workpieces with the workpiece geometry, meeting the surface treatment needs of different specifications of workpieces without adjusting equipment parameters. It is particularly suitable for the uniform control of multi-scale coatings on irregularly shaped castings.

[0038] Please refer to Figures 3 to 5 The guide assembly 6 includes a lead screw 61, a lead screw seat 62, and a rotating component 63. The lead screw 61 is vertically fixed to the lower end face of the support plate 1, and the lead screw 61 is connected to the outer side of the lead screw 61 with a lead screw seat 62 that cooperates with the lead screw 61. The lead screw seat 62 is rotatably connected to the transport table 3 through the rotating component 63.

[0039] In use, the lead screw 61 is vertically fixed at the bottom center point of the support plate 1. When the casting is placed on the upper surface of the support plate 1, the casting presses the support plate 1 and the lead screw 61 downward. When the lead screw 61 moves downward, the conveyor table 3 restricts the downward movement of the lead nut. During the movement of the lead screw 61, the lead nut is driven to rotate by the thread. The cooperation between the lead screw 61 and the lead nut restricts the movement path of the support plate 1, making the movement path of the support plate 1 vertical, which helps to improve the stability of the movement of the support plate 1.

[0040] Please refer to Figure 5 A fan 7 is coaxially fixedly connected to the outer side of the wire seat 62.

[0041] In use, when the screw nut 62 rotates, it can drive the fan 7 to rotate coaxially. When the support plate 1 moves downward, it drives the screw nut 62 to rotate through the screw rod 61. At the same time, since the screw nut 62 is fixedly connected to the fan 7, it can drive the fan 7 to rotate.

[0042] Please refer to Figures 3 to 5 The rotating component 63 includes a convex ring 631 and a bearing 632, and the upper and lower ends of the fan 7 are coaxially fixed with convex rings 631, and the outer side of the convex ring 631 is fitted with a bearing 632 with clearance.

[0043] Please refer to Figure 4 A limiting ring 31 is fixed to the upper end face of the transport platform 3, and the bottom surface of the convex ring 631 is in contact with the bottom inner wall of the limiting ring 31.

[0044] In use, first install the bearing 632 inside the limiting ring 31. Then, pass the fan 7, with the screw nut 62 fixed to it, through the screw 61 and coaxially install it on the upper end of the limiting ring 31. Then, move the screw nut 62 downwards until the convex ring 631 is inserted into the bottom inner side of the limiting ring 31. Install the convex ring 631 at the bottom of the fan 7 inside the bearing 632 with a clearance fit. When the screw 61 moves downwards, the screw nut 62 cannot move downwards along the axis because it is blocked by the transport table 3 through the limiting ring 31. The screw 61 and the screw nut 62... The threaded contact between the threads generates a tangential force, which is decomposed into a torque that causes the thread nut 62 to rotate. The convex ring 631 on the fan 7 is connected to the limiting ring 31 through the bearing 632, which makes the circumferential frictional resistance of the fan 7 weak. When rotating, the original sliding friction between the convex ring 631 and the limiting ring 31 is transformed into rolling friction, which greatly reduces the coefficient of friction, reduces energy loss and wear, and thus enables the fan 7 to rotate around the axis of the bearing 632.

[0045] During the rotation of fan 7, one side of the fan blades cuts through the air, creating a pressure difference. When the casting is placed on the upper end of the support plate 1, the support plate 1 moves downward. At this time, the fan blades on fan 7 rotate, using the fan blades to accelerate the airflow above fan 7 and increase the wind force passing through the through hole 101. At the same time, when the support plate 1 moves upward, fan 7 reverses, causing the airflow at the upper end of the fan blades to quickly pass through fan 7. Fan 7 can accelerate the airflow velocity at the through hole 101 and form a directional adsorption airflow field to remove loose powder during the downward movement of the casting support plate 1. During the upward movement, a reverse blowing airflow is generated to further peel off residual adhering powder. The dual airflow path forms a self-cleaning cycle, which significantly improves the peeling integrity of powder coatings on complex surfaces.

[0046] Please refer to Figure 3 The upper middle part of the transport platform 3 is fixed with a support frame 8, and the upper end of the support frame 8 is provided with a ventilation opening 81, and the height of the support frame 8 is higher than the height of the fan 7.

[0047] In use, the support frame 8 is placed on the upper end of the fan 7. At this time, the bottom of the support frame 8 is fixed on the transport table 3. By fixing the support frame 8 between the fan 7 and the support plate 1, when the support plate 1 moves downward, when the lower end surface of the support plate 1 contacts the support frame 8, it can prevent the support plate 1 from continuing to move downward. Thus, the support frame 8 can protect the fan 7, which helps to reduce the situation where the support plate 1 squeezes the fan 7 due to the excessive weight of the casting and affects the continued rotation of the fan 7. At the same time, it helps to protect the fan 7. Also, when the nut seat 62 reverses, the support frame 8 is used to block the nut seat 62 from moving upward.

[0048] Please refer to Figures 1 to 2 The upper end of the support plate 1 is fixed with a plurality of rectangular strip-shaped protrusions 102.

[0049] When a smooth and flat casting is placed on the upper surface of the support plate 1, the casting completely blocks the through hole 101, which can easily lead to poor airflow between the two when the casting is picked up, making it inconvenient to pick up. The protrusion 102 lifts the casting, making it easier for airflow to pass through the through hole 101.

[0050] Please refer to Figures 1 to 2 A sealing strip 21 is fixed at the connection between the rubber ring 2, the support plate 1 and the transport platform 3.

[0051] By using the sealing strip 21 to increase the sealing of the connection between the rubber ring 2, the support plate 1 and the transport platform 3, the gas loss from the connection between the rubber ring 2, the support plate 1 and the transport platform 3 is reduced when the volume of the sealed chamber 4 changes, ensuring that the pressure field energy is concentrated on the directional airflow at the through hole 101.

[0052] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the continuous manufacturing feeding device provided by this utility model.

[0053] In use, the protruding ring 631 at the bottom of the fan 7 is installed on the inner side of the bearing 632 with clearance fit, and the bearing 632 is installed in the limiting ring 31;

[0054] After the casting is placed on the upper end of the support plate 1, the weight of the casting itself drives the support plate 1 and the lead screw 61 to move downward along the axis of the lead screw 61 and compress the support spring 5. At this time, the volume of the sealed chamber 4 is reduced, and the lead screw seat 62 and the fan 7 are rotated coaxially. The reduction in the volume of the sealed chamber 4 generates a positive pressure airflow from the sealed chamber 4 to the through hole 101. The rotation of the fan 7 accelerates this airflow speed, and the powder at the bottom of the casting can be blown away during the blowing process.

[0055] After the coating is applied to the casting, the casting is lifted upwards. The elastic restoring force released by the support spring 5 drives the support plate 1 to move upwards. At this time, the volume inside the sealed chamber 4 increases. During the expansion of the volume of the sealed chamber 4, a pressure difference is formed inside and outside the sealed chamber 4, which allows outside air to enter the sealed chamber 4 through the through hole 101. At the same time, during the airflow, the coating powder at the bottom of the casting is carried into the sealed chamber 4.

Those skilled in the art should understand that this disclosure is not limited to the above embodiments.
