Description

Technical Field

[0001] This utility model relates to the technical field of roller cooling devices, and in particular to a cooling device for umbrella handle injection molded parts. Background Technology

[0002] The umbrella handle is a crucial component of an umbrella. It's typically made of plastic, usually in a columnar shape, and manufactured using injection molding. After injection molding, the handle generally retains a high residual temperature, so it needs to cool down before subsequent assembly (i.e., assembling the handle with other parts). In actual manufacturing, the molded part can be placed on a support to cool. A perforated support structure can aid in heat dissipation, resulting in better cooling. However, after cooling, the molded part needs to be folded up again, which takes considerable time and reduces overall efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cooling device for injection-molded umbrella handles, which solves the problem that the time required to fold up the injection-molded parts after cooling in existing technologies leads to a decrease in overall efficiency.

[0004] According to an embodiment, a cooling device for an injection-molded umbrella handle is provided, which includes a mounting frame. A base plate is fixedly connected to the bottom of the mounting frame, and a discharge hopper that communicates with the inside of the mounting frame and extends to one end of the mounting frame is also fixedly connected to the base plate. Multiple rollers are rotatably arranged inside the mounting frame, and all rollers are equidistantly arranged from the end of the mounting frame away from the discharge hopper to the end closer to the discharge hopper. A stop bar is also laterally movable inside the mounting frame. The stop bar is located above all rollers and between the discharge hopper and the roller closest to the discharge hopper. The movement of the stop bar can make the distance between it and the nearest roller less than or equal to the distance between adjacent rollers. In this solution, multiple support rollers are installed within the mounting frame, with the spacing between the rollers being less than the diameter of the injection molded part. This allows the injection molded part to be placed on the rollers for cooling. During the cooling process, a baffle can be moved closer to the rollers to prevent the injection molded part from falling below. After cooling, the baffle is moved to increase the distance between the baffle and the adjacent roller. Then, with the help of the rollers' rotation, the injection molded part is efficiently moved to the interval and falls into the discharge hopper below, where it is discharged. This increases the efficiency of recycling the injection molded part, thus improving overall efficiency and solving the problem in existing technologies where the time required to collect the injection molded part after cooling leads to a decrease in overall efficiency.

[0005] Furthermore, an air inlet box is fixedly connected to the side of the mounting frame away from the discharge hopper, and the air inlet box is also connected to a blower.

[0006] Furthermore, a perforated plate is fixedly connected inside the mounting frame. The perforated plate has multiple through holes. An inclined plate is fixedly connected between the perforated plate and the base plate to form an air outlet cavity together with the mounting frame and the base plate. The air inlet box is connected to the air outlet cavity.

[0007] Furthermore, an air guide pipe is fixedly connected inside the air inlet box. One end of the air guide pipe extends to the outside of the air inlet box and is connected to the blower. The air guide pipe is parallel to the idler roller and multiple air outlet pipes are fixedly connected to it along the axial direction. All air outlet pipes extend into the mounting frame.

[0008] Furthermore, a pair of sliding grooves perpendicular to the idler roller are provided on the inner wall of the mounting frame. The two sliding grooves are located above the idler roller and between the discharge hopper and an adjacent idler roller. The two ends of the stop rod are respectively slidably engaged with the two sliding grooves.

[0009] Furthermore, each end of the stop bar is fixedly connected to a sliding block, and the two sliding blocks are slidably engaged with the two sliding grooves respectively.

[0010] Furthermore, rotating shafts are fixedly connected to both ends of the roller, and the two rotating shafts are rotatably connected to the inner wall of the mounting frame.

[0011] Furthermore, the inclined plate is set at an angle with its lower end close to the discharge hopper, and a roller adjacent to the stop bar has a vertical projection on the inclined plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By setting multiple support rollers within the mounting frame for placing injection molded parts, and by moving the baffles closest to the support rollers to prevent the injection molded parts from accidentally falling into the discharge hopper below, the baffles can be moved after cooling to increase the distance between the baffles and the adjacent support rollers. Then, with the help of the rotation of the support rollers, the injection molded parts are efficiently moved to the gaps and fall into the discharge hopper below, where they are discharged. This method improves the efficiency of recycling injection molded parts and thus helps to improve overall efficiency. It solves the problem in the prior art where the time required to collect the injection molded parts after cooling is relatively long, resulting in a decrease in overall efficiency.

Figure 2 ; Figure 3 for Figure 2 Enlarged schematic diagram of a local structure at point A; Figure 4 for Figure 2 Enlarged schematic diagram of the local structure at point B; In the above attached figures: Mounting frame 1, base plate 2, discharge hopper 3, idler roller 4, stop bar 5, sliding groove 6, sliding block 7, rotating shaft 8, air inlet box 9, air guide pipe 10, air outlet pipe 11, perforated plate 12, inclined plate 13, air outlet cavity 14, column 15. Detailed Implementation

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1-3 As shown, this embodiment provides a cooling device for injection-molded umbrella handles, which includes a mounting frame 1. A base plate 2 is fixedly connected to the bottom of the mounting frame 1, and a discharge hopper 3, which communicates with the inside of the mounting frame 1 and extends to one end of the mounting frame 1, is also fixedly connected to the base plate 2. The mounting frame 1 can be a horizontally arranged rectangular frame structure. The discharge hopper 3 is located diagonally below one end of the long side. Multiple rollers 4 are rotatably arranged inside the mounting frame 1, and all rollers 4 are equidistantly arranged from the end of the mounting frame 1 away from the discharge hopper 3 to the end closer to the discharge hopper 3. The distance between the rollers 4 can be small to prevent the injection-molded parts from falling to the bottom, that is, the distance between them is less than the diameter of the injection-molded parts. Furthermore, a baffle 5 is also laterally movable inside the mounting frame 1. The baffle 5 is located above all the rollers 4 and between the discharge hopper 3 and the roller 4 closest to the discharge hopper 3. The movement allows the distance between the molded part and the nearest idler roller 4 to be less than or equal to the distance between adjacent idler rollers 4. Multiple idler rollers 4 can be used to place the injection molded part, allowing it to cool. During cooling, the baffle 5 can be moved to the nearest position to the idler roller 4 to prevent the injection molded part from accidentally falling below. After cooling, the baffle 5 is moved away from the idler roller 4, increasing the distance between the baffle 5 and the nearest idler roller 4. When this distance is greater than the diameter of the injection molded part, the rotation of the idler roller 4 allows the injection molded part to move towards the baffle 5 on the idler roller 4 (moving in a rolling manner), then fall downwards and be discharged through the discharge hopper 3. This increases the efficiency of recycling the injection molded part, thus improving overall efficiency and solving the problem in the prior art where the time required to collect the cooled injection molded part leads to a decrease in overall efficiency.

[0016] like Figure 1-3 As shown, a pair of sliding grooves 6 perpendicular to the idler roller 4 are provided on the inner wall of the mounting frame 1. The two sliding grooves 6 are located above the idler roller 4 and between the discharge hopper 3 and an adjacent idler roller 4. The two ends of the stop rod 5 are respectively slidably engaged with the two sliding grooves 6. Specifically, sliding blocks 7 are fixedly connected to the two ends of the stop rod 5, and the two sliding blocks 7 are respectively slidably engaged with the two sliding grooves 6. In this way, the position of the stop rod 5 can be adjusted by manual movement, moving it closer to or further away from the adjacent idler roller 4. In a more detailed scheme, the two ends of the idler roller 4 are respectively fixedly connected with rotating shafts 8, and the two rotating shafts 8 are respectively rotatably connected to the inner wall of the mounting frame 1, thereby realizing the rotation setting of the idler roller 4.

[0017] like Figure 1-4 As shown, to improve cooling efficiency, an air inlet box 9 is fixedly connected to the side of the mounting frame 1 away from the discharge hopper 3. An air guide pipe 10 is fixedly installed inside the air inlet box 9. The air guide pipe 10 is parallel to the roller 4 and extends one end outside the air inlet box 9, connected to a blower. Multiple air outlet pipes 11 are also installed on the air guide pipe 10, extending towards the inside of the mounting frame 1. When the blower is running, air can be introduced into the air guide pipe 10 and then guided into the mounting frame 1 through the air outlet pipes 11, thus making the airflow in the mounting frame 1 faster and helping to improve cooling efficiency. Furthermore, the air inlet pipes are equidistantly arranged along the axial direction of the air guide pipe 10 to more evenly introduce air. Even further, a perforated plate 12 is fixedly connected inside the mounting frame 1. The plate 12 has several vertically penetrating holes that allow air to pass through. The perforated plate 12 is also fixedly connected to an inclined plate 13. The inclined plate 13, the perforated plate 12, the mounting frame 1, and the base plate 2 together form an air outlet cavity 14 that communicates with the air inlet box 9. The perforations allow the air supplied by the blower to pass through the mounting frame 1 and blow out from bottom to top, thereby improving the cooling efficiency. Furthermore, the inclined plate 13 is inclined, with the lower end of the inclined plate 13 close to the discharge hopper 3. A roller 4 adjacent to the baffle 5 has a vertical projection on the inclined plate 13, so that the injection molded parts falling between the baffle 5 and the roller 4 can fall more smoothly into the discharge hopper 3, achieving smooth discharge. In a more detailed scheme, columns 15 are also fixedly connected at the four corners of the mounting frame 1 so that the overall structure stands on the ground.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
