Description

Technical Field

[0001] This utility model relates to the field of cross-flow fan impeller production, and in particular to a recycling device for cross-flow fan impeller assemblies. Background Technology

[0002] When injection molding cross-flow fan impellers, the impeller assembly needs to be embedded in the impeller plastic disc. Products with poor injection molding that cannot be adjusted are scrapped. Scrapped products need to be disassembled to separate the impeller assembly from the impeller plastic disc, allowing the impeller assembly to be reused to produce new products. Currently, the disassembly of scrapped products usually uses a stamping die including an upper and lower die. By abutting the lower die against the impeller assembly and pressing the stamping parts of the upper die against the impeller plastic disc, the impeller assembly is separated from the impeller plastic disc. The impeller assembly is a metal component used to house the cross-flow fan impeller shaft.

[0003] However, after stamping, the separated ring-shaped plastic part is easily stuck on the lower mold and is not easy to remove. Operators need to clean the ring-shaped plastic part stuck on the lower mold before they can continue to dismantle the scrapped products, resulting in low dismantling efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology where the annular plastic part is easily stuck in the lower mold after stamping and is difficult to remove, and to provide a recycling device for cross-flow fan impeller assembly.

[0005] This utility model provides a recovery device for cross-flow wind turbine impeller assembly, comprising: The upper stamping die and the lower stamping die are provided. The upper stamping die is provided with a cutter assembly for cutting the impeller plastic disc and a stamping mechanism for abutting the impeller plastic disc. The lower stamping die is provided with a support assembly for abutting the impeller plastic disc and a stamping bearing for abutting the impeller assembly. The cutter assembly and the support assembly are arranged opposite to each other, and the stamping mechanism and the stamping bearing are arranged opposite to each other. The stamping mechanism is provided with an inner cavity for accommodating the impeller assembly, and the stamping bearing can enter the inner cavity. The stamping mechanism and the support assembly are spaced apart. The upper stamping die moves vertically, and the stamping mechanism can crush the impeller plastic disc.

[0006] This utility model discloses a recycling device for a cross-flow fan impeller assembly. The scrapped component is placed in a lower mold, a support assembly supports the impeller plastic disc, a stamping platform supports the impeller assembly, a stamping mechanism abuts against the impeller plastic disc on the outer edge of the impeller assembly, and a cutter assembly abuts against the impeller plastic disc. When the upper stamping mold moves vertically, the cutter assembly and the stamping mechanism move with the upper stamping mold. The cutter assembly cuts the impeller plastic disc, and the stamping mechanism separates the impeller assembly from the impeller plastic disc. The cutter assembly cleaves the impeller plastic disc, and as the stamping mechanism presses down, it crushes the impeller plastic disc from its circumferential surface, causing the impeller plastic disc to break at the cut point, thus preventing the impeller plastic disc from being fitted onto the stamping platform. The relative arrangement of the cutter assembly and the support assembly ensures that the impeller plastic disc can be cut. The separated impeller assembly enters the inner cavity.

[0007] Preferably, the cutting head assembly includes a first cutter and a second cutter, which are disposed opposite to each other on both sides of the stamping mechanism. The first cutter is connected to the upper stamping die, and the second cutter is connected to the upper stamping die. The first cutter is disposed opposite to the support assembly, and the second cutter is disposed opposite to the support assembly.

[0008] The first and second cutters are positioned opposite each other on both sides of the stamping mechanism. The first cutter is spaced apart from the stamping mechanism, and the second cutter is also spaced apart. When the upper die of the stamping mechanism is pressed down, the impeller plastic disc is simultaneously squeezed by the first and second cutters, resulting in symmetrical force and preventing displacement of the impeller plastic disc. This allows the first and second cutters to cut the impeller plastic disc on opposite sides of the stamping mechanism, making it easier for the impeller plastic disc to be squeezed and destroyed by the stamping mechanism.

[0009] Preferably, the support assembly includes a first pad and a second pad, which are disposed opposite to each other on both sides of the stamping platform. The first pad is disposed opposite to the first cutter, and the second pad is disposed opposite to the second cutter.

[0010] The first and second pads are spaced apart from the stamping bearing to avoid interfering with the stamping mechanism. The first and second pads are positioned opposite each other to support the symmetrical position of the impeller plastic disc, thereby ensuring the stability of the impeller plastic disc and preventing it from shifting and lodging on the stamping bearing. The first pad is positioned opposite to the first cutter, and the second pad is positioned opposite to the second cutter, ensuring that both sides of the impeller plastic disc are cut open.

[0011] Preferably, it further includes a guide component, which is connected to the upper stamping die and the lower stamping die.

[0012] By setting up guide components, it is easy to align the centers of the upper and lower stamping dies, enabling rapid positioning, thereby reducing stamping damage to the impeller assembly and accelerating work efficiency.

[0013] Preferably, the guide assembly includes two guide rods disposed opposite to each other on both sides of the stamping mechanism, one end of the guide rod being connected to the upper stamping die and the other end being connected to the lower stamping die.

[0014] Two guide rods are used to accurately position the upper and lower stamping dies. The guide rods are set vertically.

[0015] Preferably, the guide rod includes a guide sleeve and a guide post, the guide sleeve and the guide post are slidably connected, the guide sleeve is connected to the upper stamping die, the guide post is connected to the lower stamping die, and the guide post and the guide sleeve are detachably connected.

[0016] The guide column and guide sleeve are detachably connected, which makes it easy for operators to place the cross-flow fan impeller on the stamping platform and facilitates maintenance.

[0017] Preferably, the lower end of the stamping mechanism is constructed as a tapered structure.

[0018] The lower end of the stamping mechanism is constructed as a conical structure. During the contact process between the stamping mechanism and the impeller plastic disc, the contact area between the stamping mechanism and the impeller plastic disc gradually expands towards the outer side of the impeller plastic disc, which is beneficial for the impeller plastic disc to be destroyed during the extrusion process.

[0019] Preferably, the stamping support is cylindrical and has positioning posts.

[0020] The positioning pin passes through the shaft hole of the impeller assembly, thereby accurately positioning the cross-flow fan impeller on the stamping bearing; the inner cavity is a cylindrical chamber; the diameter of the inner cavity is larger than the diameter of the impeller assembly, which facilitates the impeller assembly to enter the inner cavity, and in some embodiments the inner cavity is clearance-fitted with the stamping bearing.

[0021] Preferably, the lower end of the cutter head assembly extends beyond the lower end of the stamping mechanism.

[0022] The lower end of the cutter head assembly extends 1mm beyond the lower end of the stamping mechanism. When dismantling a 3mm thick impeller plastic disc, the stamping mechanism will abut against the impeller plastic disc after the impeller plastic disc is cut, thus damaging the impeller plastic disc.

[0023] Preferably, the inner cavity is provided with a pushing mechanism, which passes through the upper stamping die and is slidably connected to the upper stamping die.

[0024] After the upper stamping die is raised, the pushing mechanism pushes the impeller assembly located in the inner cavity, causing the impeller assembly to separate from the stamping mechanism; the separated impeller assembly enters the inner cavity, and then the pushing mechanism pushes the impeller assembly out of the inner cavity, allowing the impeller assembly to be easily removed manually.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a recycling device for cross-flow fan impeller assemblies. The scrapped components are placed in a lower mold, a support assembly supports the impeller plastic disc, a stamping platform supports the impeller assembly, a stamping mechanism abuts against the impeller plastic disc on the outer edge of the impeller assembly, and a cutter assembly abuts against the impeller plastic disc. When the upper stamping mold moves vertically, the cutter assembly and stamping mechanism move with the upper stamping mold. The cutter assembly cuts the impeller plastic disc, and the stamping mechanism separates the impeller assembly from the impeller plastic disc. The cutter assembly cleaves the impeller plastic disc, and as the stamping mechanism presses down, it crushes the impeller plastic disc from its circumferential surface, causing it to break at the cut point, thus preventing the impeller plastic disc from being mounted on the stamping platform. The relative arrangement of the cutter assembly and the support assembly ensures that the impeller plastic disc can be cut. The separated impeller assembly enters the inner cavity, and then a pushing mechanism pushes the assembly out of the inner cavity, allowing for easy manual removal of the assembly. 2. This utility model provides a recycling device for cross-flow fan impeller assemblies. When dismantling the cross-flow fan impeller, the blade assembly cuts the impeller plastic disc, creating cracks. When the stamping mechanism crushes the impeller plastic disc, the fan blade breaks through the cracks, thus destroying the impeller plastic disc. This prevents the impeller plastic disc from being mounted on the stamping bearing, thereby improving the dismantling efficiency of scrapped cross-flow fan impellers and has good economic and practical value.

[0035] The cross-flow fan blade 100 is composed of an impeller plastic disc 101 and an impeller assembly 102.

[0036] By placing the scrapped part in the lower mold, the support assembly 7 supports the impeller plastic disc 101, the stamping platform 5 supports the impeller assembly 102, the stamping mechanism 4 abuts against the impeller plastic disc 101 on the outer edge of the impeller assembly 102, and the blade abuts against the impeller plastic disc 101; when the upper stamping mold 1 moves vertically, the cutter assembly 3 and the stamping mechanism 4 move with the upper stamping mold 1, the cutter assembly 3 cuts the impeller plastic disc 101, and the stamping mechanism 4 separates the impeller assembly 102 from the impeller plastic disc 101; The cutter head assembly 3 cuts the impeller plastic disc 101. As the stamping mechanism 4 presses down, it squeezes and breaks the impeller plastic disc 101 from the circumferential surface, causing the impeller plastic disc 101 to break at the cut point, thus preventing the impeller plastic disc 101 from being fitted onto the stamping support 5. The relative arrangement of the cutter head assembly 3 and the support assembly 7 ensures that the impeller plastic disc 101 can be cut. The separated impeller assembly 102 enters the inner cavity, and the stamping mechanism 4 can squeeze and break the impeller plastic disc 101.

[0037] In one or more embodiments, the cutter head assembly 3 is composed of a first cutter 31 and a second cutter 32.

When the cutting parts are pressed down, the impeller plastic disc 101 is cut off.

[0038] In an optional embodiment, the support component 7 is composed of a first pad 71 and a second pad 72. The first pad 71 and the second pad 72 are disposed opposite to each other on both sides of the stamping base 5.

Specifically, the first pad 71 and the second pad 72 are respectively spaced apart from the stamping base 5.

[0039] In one or more embodiments, a guide assembly 6 is also included. The guide assembly 6 is connected to the upper stamping die 1 and the lower stamping die 2. Specifically, the guide assembly 6 consists of two guide rods 61 arranged opposite to each other on both sides of the stamping mechanism 4. One end of the guide rod 61 is connected to the upper stamping die 1 and the other end is connected to the lower stamping die 2. The guide rods 61 guide the stamping mechanism 4 to be accurately positioned, avoiding damage to the impeller assembly 102. Both guide rods 61 are arranged vertically.

[0040] In an optional embodiment, the guide rod 61 is composed of a guide sleeve 611 and a guide post 612. The guide sleeve 611 and the guide post 612 are slidably connected. The guide sleeve 611 is connected to the upper stamping die 1, and the guide post 612 is connected to the lower stamping die 2. The guide post 612 and the guide sleeve 611 are detachably connected. Specifically, the guide post 612 is inserted into the guide sleeve 611 from the end of the guide sleeve 611. Both the guide sleeve and the guide sleeve 611 are vertically arranged.

[0041] In one or more embodiments, the lower end of the stamping mechanism 4 is constructed as a conical structure; the lower end of the stamping mechanism 4 is constructed as a conical structure, and during the contact process between the stamping mechanism 4 and the impeller plastic disc 101, the contact area between the stamping mechanism 4 and the impeller plastic disc 101 gradually expands towards the outside of the impeller plastic disc 101, which is beneficial to the impeller plastic disc 101 being destroyed during the extrusion process, and the bottom end of the conical structure is provided with an opening communicating with the inner cavity.

[0042] In one or more embodiments, the stamping base 5 is cylindrical and has a positioning post 9. The diameter of the stamping base 5 is smaller than the diameter of the impeller assembly 102, and the diameter of the inner cavity is larger than the diameter of the impeller assembly 102. Specifically, the diameter of the impeller assembly 102 is 30 mm, the diameter of the inner cavity is 32 mm, and the diameter of the stamping base 5 is 28 mm. The stamping base 5 is provided with a positioning post 9 that matches the shaft hole of the impeller assembly 102, so that the impeller assembly 102 is accurately positioned.

Both the pushing block 83 and the damping element 82 are disposed in the inner cavity. The pushing block 83 can slide within the inner cavity and is used to push the impeller assembly 102. After the mechanism 4 is pressed down, the impeller assembly 102 enters the inner cavity and abuts against the push block 83, causing the spring, which acts as a damping element 82, to compress. After the stamping mechanism 4 is lifted away from the stamping platform 5, the damping element 82 pushes the push block 83 to abut against the impeller assembly 102, causing the impeller assembly 102 to disengage from the stamping mechanism 4. The separated impeller assembly 102 enters the inner cavity, and then the push mechanism 8 pushes the impeller assembly 102 out of the inner cavity, allowing the impeller assembly 102 to be easily removed manually.

The stamping mechanism 4 continues to penetrate 2mm, so that the impeller plastic disc 101 is crushed by the stamping mechanism, thereby avoiding damage to the impeller assembly 102 and separating the impeller assembly 102 from the impeller plastic disc 101.
