Description

Technical Field

[0001] This application relates to the technical field of sheath production and processing, and in particular to a sheath forming equipment. Background Technology

[0002] PVC sheaths are PVC dip-coated products with a wide range of applications, mainly used in air conditioners, refrigerators, microwave ovens, washing machines, automobiles, motorcycles and other related products.

[0003] The related sheath molding equipment includes a frame, on which a vertically sliding lifting support is mounted. Two rotating supports are rotatably connected to the lifting support, and a mold frame is installed between the two rotating supports. The mold frame includes a mold plate connected to the rotating supports, and forming columns are mounted on the mold plate. A storage box for storing PVC raw materials is located below the mold frame.

[0004] During the production process, the rotating bracket rotates the mold frame to set the forming column vertically downwards. Then, the lifting bracket lowers the height so that the end of the forming column is immersed in the liquid material in the container. After a period of time, the lifting device rises to completely detach the forming column from the PVC raw material. Then, the rotating bracket rotates back to its original position so that the forming column is vertically upwards. Once the PVC raw material cools and solidifies, the PVC sheath is formed.

[0005] During the process of rotating the support to make the shaping column vertical, the PVC raw material will flow to the side of the shaping column opposite to the direction of rotation under the action of gravity. Although the PVC raw material will not be too concentrated due to its poor fluidity, it can still easily lead to uneven wall thickness of the PVC sheath, and even bulges on one side of the sheath. Summary of the Invention

[0006] To improve the yield rate of PVC sheaths, this application provides a sheath molding device.

[0007] This application provides a sheath forming equipment, which adopts the following technical solution: A sheath forming device includes a frame, a mounting frame on the frame, a forming structure and a flipping structure for driving the forming structure to rotate, a lifting structure for driving the mounting frame to rise and fall, and a storage structure for storing raw materials below the forming structure. The forming structure includes a mold plate mounted on the mounting frame, a forming column on the mold plate, and the flipping structure includes two mounting plates rotatably connected to the mounting frame, with the mold plate positioned between the two mounting plates. A rotating structure for driving the forming column to rotate is provided on the mounting plate.

[0008] By adopting the above technical solution, in the initial state, the forming column is located above the mold plate; the forming structure is flipped by the flipping structure so that the forming column is located below the mold plate; the forming structure is moved towards the storage structure by the lifting structure, so that the PVC mixed material in a high-temperature molten state adheres to the forming column; then the lifting structure and the flipping structure are reset until the PVC raw material on the forming structure cools down and forms a PVC sheath; during the process of the flipping structure driving the mold plate and the forming column to flip and reset, the forming column is driven to rotate by the rotating structure, so that the flipping structure and the rotating structure work synchronously, so that the PVC mixed material on the forming column is evenly distributed, so that the wall thickness of the formed PVC sheath is uniform, and the yield of PVC sheath is improved.

[0009] Optionally, the flipping structure further includes a fixing seat on the side of the mounting plate facing the mold plate, a locking member connecting the fixing seat and the mold plate, and a flipping drive member for driving the mounting plate to rotate on the mounting bracket.

[0010] By adopting the above technical solution, the flipping drive component drives the mounting plate to rotate, causing the mounting plate, mold plate, and forming column to rotate together, aligning the forming column with the storage structure. Subsequently, the lifting structure can drive the forming column to move towards the storage structure. When the forming column is lower than the mounting plate, the PVC mixture material in a high-temperature molten state adhered to it flows away from the mounting plate, which will cause uneven wall thickness of the PVC sheath. However, by rotating the forming column, when the forming column is higher than the mounting plate, the PVC mixture material adhered to the forming column flows towards the mounting plate, making the wall thickness of the formed PVC sheath uniform.

[0011] Optionally, the flipping drive includes a flipping motor mounted on a mounting bracket, the output shaft of which is connected to the mounting plate.

[0012] Optionally, the fixing seat is located on the side of the mold plate away from the forming column. The fixing seat has a fixing groove with a T-shaped cross-section facing the mold plate. The locking component includes a locking bolt that is slidably disposed in the fixing groove. A pressure plate located on the side of the mold plate away from the fixing seat is sleeved on the shank of the locking bolt. A locking nut is threaded onto the locking bolt. A pad is provided between the pressure plate and the fixing seat. The pad is located on the side of the locking bolt away from the mold plate. When the end face of the pressure plate facing the fixing seat abuts against the end face of the mold plate away from the fixing seat, the end face of the pressure plate facing the fixing seat abuts against the end face of the pad away from the fixing seat.

[0013] By adopting the above technical solution, the T-slot design allows the locking bolt to move only within the fixed slot, enabling the installation of mold plates of different sizes and improving the adaptability of the locking components. The locking bolt, pressure plate, locking nut, and pad are used to connect and fix the fixed seat to the pressure plate.

[0014] Optionally, the forming column is provided with a mounting shaft on the side facing the mold plate, the mold plate is provided with a through hole for the mounting shaft to pass through, the rotating structure includes a driven bevel gear sleeved on the mounting shaft and an operating rod rotatably connected to the mounting plate, the operating rod is sleeved with a driving bevel gear, the driving bevel gear and the driven bevel gear mesh with each other, and the mounting plate is provided with a rotary drive component for driving the mounting shaft to rotate.

[0015] By adopting the above technical solution, the rotary drive component drives the active bevel gear to rotate. Since the active bevel gear and the driven bevel gear mesh with each other, the active bevel gear drives the driven bevel gear and the molding column to rotate. During the rotation of the mounting plate relative to the mounting frame, the molding column rotates, so that the PVC mixed material is evenly distributed in the circumference of the molding column, making the wall thickness of the molded PVC sheath uniform and improving the qualification rate of the PVC sheath.

[0016] Optionally, the rotary drive includes a rotary motor disposed on the side of the mounting plate away from the fixed base, and the output shaft of the rotary motor is connected to the operating lever.

[0017] Optionally, a circular shaft is provided on the side of the mounting plate away from the fixed seat. The circular shaft is rotatably connected to the mounting frame. The rotation drive includes a sun gear sleeved on the circular shaft and a planetary gear sleeved on the operating lever. The sun gear is fixedly connected to the mounting frame. The sun gear and the planetary gear mesh with each other. The sun gear and the planetary gear have the same structure.

[0018] By adopting the above technical solution, when the flipping structure rotates 180 degrees, the planetary gear rolls around the outside of the sun gear. Since the sun gear and planetary gear have the same structure, the planetary gear rotates 360 degrees around the axis of the operating lever. This causes the driving bevel gear to rotate 360 ​​degrees, so that the PVC mixed material is evenly distributed around the circumference of the molding column, making the wall thickness of the molded PVC sheath uniform and improving the qualification rate of the PVC sheath.

[0019] Optionally, multiple forming columns and mounting shafts are provided, and the rotating structure further includes a linkage component that links the multiple mounting shafts. The linkage component includes a linkage gear sleeved on each mounting shaft, and two adjacent linkage gears mesh with each other.

[0020] By adopting the above technical solution, the mounting shafts are linked by a linkage component, so that when the rotating structure drives any one mounting shaft to rotate, it can drive the other mounting shafts to rotate.

[0021] Optionally, the mold plate is provided with a stripping structure for stripping the product. The stripping structure includes a stripping plate slidably disposed on the mounting plate and a stripping drive on the mounting plate. The stripping plate has an insertion hole for the forming column to pass through. The stripping drive is used to drive the stripping plate to move along the axial direction of the forming column.

[0022] By adopting the above technical solution, the molding structure needs to be moved into the storage structure. The stripping drive first drives the stripping plate to move towards the mold plate, so that the molding column is exposed. Then, the rolling structure drives the molding structure to rotate, so that the molding column faces downward. Then, the lifting structure moves the molding structure into the storage structure, so that the PVC mixed material in a high-temperature molten state adheres to the molding column. After the PVC sleeve is formed in the molding column, the stripping cylinder drives the stripping plate to move away from the mold plate, so that the stripping plate drives the PVC sleeve to detach from the molding column.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Initially, the forming column is located above the mold plate. The forming structure is flipped by the flipping structure, so that the forming column is located below the mold plate. The forming structure is then moved towards the storage structure by the lifting structure, so that the PVC mixture material in a high-temperature molten state adheres to the forming column. Then the lifting structure and the flipping structure are reset until the PVC raw material on the forming structure cools down and forms a PVC sheath. During the flipping structure driving the mold plate and the forming column to flip and reset, the forming column is driven to rotate by the rotating structure, so that the flipping structure and the rotating structure work synchronously, so that the PVC mixture material on the forming column is evenly distributed, so that the wall thickness of the formed PVC sheath is uniform, and the yield of PVC sheaths is improved. 2. Set up linkage components to enable multiple forming columns to move in tandem, eliminating the need for multiple rotating structures, i.e., eliminating the need for multiple drive sources.
