Description

Technical Field

[0001] This invention relates to cable processing, specifically to a core coating and molding equipment for cable processing. Background Technology

[0002] Cables mainly consist of an outer insulation sheath and a battery core. During the cable processing, battery core coating molding equipment is required. To coat the battery core, molten coating material is generally squeezed into the coating molding chamber, and then the core is coated with the coating material.

[0003] Existing patent CN118692754B discloses a core coating molding equipment for cable processing, including a mounting base plate and a groove extrusion structure disposed at the top of the mounting base plate for pressing grooves on the surface of a first coating layer; a thickness adjustment structure disposed at the top of the mounting base plate for adjusting the thickness of the coating layer; and an air-cooling structure disposed at the top of the mounting base plate for cooling the first coating layer. The groove extrusion structure includes a support plate, which is fixedly connected to the top of the mounting base plate, and a T-shaped slide rod is fixedly connected to the side of the support plate.

[0004] This technical solution creates grooves on the surface of the first coating layer, forming a snap-fit ​​connection between the first and second coating layers. This improves the connection stability between multiple coating layers and prevents separation when coating layers of different materials are used in combination. However, this technical solution has two problems: the simple spacing grooves acting between the two coating layers are prone to lateral and tensile slippage, and the groove forming device at the coating layer is relatively complex. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a core coating and molding equipment for cable processing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a core coating molding equipment for cable processing, comprising two extrusion feeding pipes, each feeding pipe having an extrusion ring rotatably connected to one end close to the other, the extrusion ring forming multiple protrusions inward, the two limiting rings being fixedly connected by a connecting frame, a toothed ring being fixedly mounted on the surface of the connecting frame, and the toothed ring engaging with a power gear that drives the toothed ring to rotate.

[0007] Preferably, the connecting frame includes two end face rings, which are fixedly connected to the extrusion ring. The two end face rings are fixedly connected by multiple support rods, which are distributed in a ring and are concentric with the feeding pipe. A toothed ring is fixedly installed on the outer surface of the support rods, and limit rings are fixedly installed on both sides of the outer surface of the support rods. A support frame is provided below the connecting frame, and a fixing ring wrapped around the outer surface of the limit ring is fixedly installed inside the support frame.

[0008] Preferably, the support frame is trough-shaped, and a water-spraying plate is fixedly installed on the outer surface of the support rod, with the water-spraying plate pointing towards the center of the feed pipe.

[0009] Preferably, the water spraying plate and the support rod are inclined, the surface of the water spraying plate is concave downward to form a water storage groove, and a spray ring is fixedly installed on the inner ring of the support frame.

[0010] Preferably, at least two sets of telescopic sleeves are fixedly installed on the sides of the end face rings that are far apart from each other, and connecting flanges are fixedly installed on the sides of the extrusion ring and the telescopic sleeves that are close to each other, and the two connecting flanges are fixedly connected.

[0011] Preferably, the feeding pipe is provided with a feeding port and is composed of two symmetrical upper and lower parts. The inner ring of the front end of the feeding pipe is provided with a snap ring, and the outer ring of the extrusion ring is fixedly installed with a snap ring. The snap ring is rotatably connected inside the snap ring. The side of the snap ring away from the connecting frame is provided with an inclined transition part that fits against the inner wall of the feeding pipe.

[0012] Preferably, a cooling duct is fixedly installed on the outer surface of the support frame, and an air outlet pointing towards the center of the feed pipe is opened on the inner wall of the cooling duct. The cooling duct is divided into multiple sections located between the limiting ring and the toothed ring.

[0013] Preferably, the inner ring of the support frame is provided with return air chambers on both sides of the cooling air duct. The return air chambers and the cooling air duct form a closed cavity. The return air chamber is provided with a return air hole at one end of the return air chamber located inside the cooling air duct. A supply ring is sleeved on the outer surface of the return air chamber and the cooling air duct. The inner ring of the supply ring is rotatably connected to a slip ring. The inner ring of the slip ring is connected to and penetrates a connecting pipe. The circumferential surface of the supply ring is connected to and penetrates a connecting pipe.

[0014] Preferably, the pitch of the spiral groove formed by the extrusion ring is N, and the distance between the two extrusion rings is an integer multiple of N.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this cable processing core coating molding equipment, the core passes through the first feeding tube. The first layer of coating is squeezed and wrapped around the outer surface of the core inside the feeding tube, and is squeezed at the port using protrusions. As the core continues to move laterally, the protrusions keep rotating under the action of the gear ring. Therefore, the protrusions form a continuous spiral groove on the outer surface of the first layer of coating. In the next feeding tube, the coating material is supplied to cover the groove and form a new coating on the outer ring, thereby ensuring that the two layers of coating material are tightly connected and do not slip relative to each other.

[0017] This cable processing core coating molding equipment features a support frame shaped like a water trough. A water spraying plate is fixedly installed on the outer surface of the support rod, pointing towards the center of the feed pipe. This design allows the water spraying plate to disperse cooling water onto the outer surface of the coating layer, thereby cooling the coating layer. The surface of the water spraying plate is concave to form a water storage groove. A spray ring is fixedly installed on the inner ring of the support frame. This design allows the cooling water to cool the first coating layer outside the core.

[0018] The cable processing core coating molding equipment has a cooling air duct fixedly installed on the outer surface of the support frame. The inner wall of the cooling air duct has an air outlet pointing to the center of the feed pipe. Air cooled by the refrigeration unit is pumped into the interior of the cooling air duct by a blower. The cooling air duct is divided into multiple sections located between the limiting ring and the toothed ring. By using air cooling, the first coating layer can be kept clean at all times.

[0019] The cable processing core coating molding equipment has at least two sets of telescopic sleeves fixedly installed on the side of the end face rings that are far apart from each other, and connecting flanges fixedly installed on the side of the extrusion rings and telescopic sleeves that are close to each other. The two connecting flanges are fixedly connected. Since it is necessary to limit the distance between the two extrusion rings, telescopic sleeves are set to finely adjust the distance between the two extrusion rings.

[0020] The cable processing core coating molding equipment includes a connecting frame with two end face rings, which are fixedly connected to the extrusion rings. The two end face rings are fixedly connected by multiple support rods, which are distributed in a ring and are concentric with the feeding pipe. A toothed ring is fixedly installed on the outer surface of the support rods, and limit rings are fixedly installed on both sides of the outer surface of the support rods. A support frame is set below the connecting frame, and a fixing ring wrapped around the outer surface of the limit ring is fixedly installed inside the support frame. This arrangement allows the two extrusion rings to rotate synchronously and also provides space for cooling. Attached Figure Description

[0032] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0033] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0034] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0035] Example 1, as Figure 1-6 As shown, a cable processing core coating molding device includes two extrusion feed pipes 1. Each feed pipe 1 has an extrusion ring 2 rotatably connected to its closest end. Multiple protrusions 4 are formed inwardly on each extrusion ring 2. Two limiting rings 502 are fixedly connected by a connecting frame 5. A gear ring 6 is fixedly mounted on the surface of the connecting frame 5, and the gear ring 6 is engaged with a power gear 7 that drives the gear ring 6 to rotate. As the extrusion ring 2 rotates, the core moves laterally, and the protrusions 4 extrude the coating material into a spiral groove. In the next feed pipe 1, the coating material is supplied to cover the groove and form a new coating on the outer ring, thus ensuring a tight connection between the two layers of coating material and preventing relative slippage.

[0036] The connecting frame 5 includes two end face rings 501, which are fixedly connected to the extrusion rings 2. The two end face rings 501 are fixedly connected by multiple support rods 510, which are distributed in a ring and are concentric with the feed pipe 1. The toothed ring 6 is fixedly installed on the outer surface of the support rods 510. Limiting rings 502 are fixedly installed on both sides of the outer surface of the support rods 510. A support frame 508 is provided below the connecting frame 5. A fixing ring 503 wrapped around the outer surface of the limiting rings 502 is fixedly installed inside the support frame 508. This arrangement allows the two extrusion rings 2 to rotate synchronously and also provides space for cooling.

[0037] The pitch of the spiral groove formed by the extrusion ring 2 is N, and the distance between the two extrusion rings 2 is an integer multiple of N. This setting ensures that the extrusion rings 2 rotate synchronously, so that the protrusion 4 is always located in the spiral groove.

[0038] At least two sets of telescopic sleeves 506 are fixedly installed on the opposite sides of the end face rings 501. The telescopic sleeves 506 are hydraulic. The telescopic sleeves 506 on the same side are adjusted simultaneously by the same adjustment end. Connecting flanges 507 are fixedly installed on the opposite sides of the extrusion rings 2 and the telescopic sleeves 506. The two connecting flanges 507 are fixedly connected. Since it is necessary to limit the distance between the two extrusion rings 2, the telescopic sleeves 506 are set to finely adjust the distance between the two extrusion rings 2.

[0039] The support frame 508 is shaped like a water tank. An air jet mechanism is set at the tail end of the support frame 508. Before entering the next feed pipe 1, the air jet mechanism blows the water on the surface of the coating layer to keep it dry. A water spraying plate 504 is fixedly installed on the outer surface of the support rod 510. The water spraying plate 504 points to the center of the feed pipe 1. With this setting, the water spraying plate 504 can be used to disperse the cooling water on the outer surface of the coating layer, thereby cooling the coating layer.

[0040] The water spraying plate 504 and the support rod 510 are inclined. The surface of the water spraying plate 504 is concave to form a water storage groove 505. This setting can ensure that the water spraying plate 504 can temporarily store some cooling water and rotate it to the top of the battery cell for spraying, thereby uniformly cooling the battery cell. The inner ring of the support frame 508 is fixedly installed with a spray ring 509. This setting can use the spray ring 509 to spray cooling water to cool the first layer of the battery cell.

[0041] The feed pipe 1 is provided with a feed inlet 9, which is connected to the existing feed unit. The feed pipe 1 is composed of two symmetrical upper and lower parts. The inner ring of the front end of the feed pipe 1 is provided with a snap ring 10. The outer ring of the extrusion ring 2 is fixedly installed with a snap ring 11. The snap ring 11 is rotatably connected to the inside of the snap ring 10. This arrangement can ensure that the extrusion ring 2 can rotate relative to the feed pipe 1. The side of the snap ring 11 away from the connecting frame 5 is provided with an inclined transition part 12 that fits against the inner wall of the feed pipe 1. By providing the transition part 12, the connection between the extrusion ring 2 and the feed pipe 1 can be prevented from forming a protrusion, thereby forming a dead zone in the feed.

[0042] During use, the battery cell passes through the first feed tube 1. The first wrapping layer is squeezed and wrapped around the outer surface of the battery cell within the feed tube 1, and is further squeezed at the port using protrusions 4. As the battery cell continuously moves laterally, the protrusions 4 rotate under the action of the gear ring 6, thus forming continuous spiral grooves on the outer surface of the first wrapping layer. When the first wrapping layer passes through the support frame 508, the spray ring 509 sprays cooling water onto it. Simultaneously, the rotating support frame 508 uses the water-spraying plate 504 to push water toward the first wrapping layer, and... When rotated to the highest point, the water in the water storage groove 505 is dispersed from the top to the outer surface of the first layer of wrapping to cool the first layer of wrapping. The cell moves laterally into the second feed tube 1. The second feed tube 1 squeezes and wraps the second layer of wrapping in the spiral groove. Since the outlet of the second feed tube 1 is annular, the surface of the second layer of wrapping coming out of the second feed tube 1 is smooth. By filling the spiral groove with the second layer of wrapping and adhering it to the first layer of wrapping, the slippage of the two layers of wrapping caused by rotation and stretching can be avoided.

[0043] Example 2, based on Example 1, such as Figure 1 , 2 As shown in Figures 5, 7, and 8, a cooling air duct 13 is fixedly installed on the outer surface of the support frame 508. An air outlet 14 pointing towards the center of the feed pipe 1 is opened on the inner wall of the cooling air duct 13. Air cooled by the refrigeration unit is pumped into the interior of the cooling air duct 13 by a blower. The cooling air duct 13 is divided into multiple sections located between the limiting ring 502 and the toothed ring 6. By adopting a wind-cooled cooling method, the first wrapping layer can always be kept clean.

[0044] The inner ring of the support frame 508 is provided with return air chambers 15 on both sides of the cooling air duct 13. The return air chambers 15 and the cooling air duct 13 form a closed cavity. Although the temperature of the cooling gas decreases after contact with the first layer of the outer casing, there is still a temperature difference between the cooling gas and the first layer of the outer casing. Therefore, production costs can be reduced by recovering the cold air. The return air chamber 15 is provided with a return air hole 16 at one end inside the cooling air duct 13. By setting the return air hole 16 and the return air chamber 15, the blown cold air can be recovered and reused for cooling through secondary cooling. The return air chamber 15 is connected to an air extraction device to draw the cold air into the interior of the refrigeration unit. The outer surfaces of the return air chamber 15 and the cooling air duct 13 are fitted with a supply ring 18. The inner ring of the supply ring 18 is rotatably connected to a slip ring 19. The inner ring of the slip ring 19 is connected to and passes through a connecting pipe 17. The circumferential surface of the supply ring 18 is connected to and passes through a connecting pipe 20. This arrangement can ensure that the device can maintain the continuity of the pipeline while rotating.

[0045] During use, the battery cell passes through the first feed tube 1. The first layer of wrapping is squeezed and wrapped around the outer surface of the battery cell inside the feed tube 1, and is squeezed at the port using protrusion 4. As the battery cell continues to move laterally, the protrusion 4 keeps rotating under the action of the gear ring 6. Therefore, the protrusion 4 will form a continuous spiral groove on the outer surface of the first layer of wrapping. When the first layer of wrapping passes through the cooling air duct 13, the cooling air duct 13 blows out cold air to cool the first layer of wrapping. The return air cavity 15 and the return air duct recover the cold air for secondary cooling and use it for further cooling. The battery cell moves laterally into the second feed tube 1. The second feed tube 1 squeezes and wraps the second layer of wrapping in the spiral groove. Since the outlet of the second feed tube 1 is annular, the surface of the second layer of wrapping coming out of the second feed tube 1 is smooth. By filling the spiral groove with the second layer of wrapping and adhering it to the first layer of wrapping, it is possible to avoid the two layers of wrapping from slipping due to rotation and stretching.
