Description

Technical Field

[0001] This utility model belongs to the field of pipe bending technology, specifically relating to a folding pipe bending mechanism for a vacuum cleaner. Background Technology

[0002] Vacuum cleaners can be categorized by structure into upright, canister, and portable types. The working principle of a vacuum cleaner is to use an electric motor to drive blades to rotate at high speed, creating negative air pressure within a sealed casing to suck up dust and debris. Vacuum cleaners mainly consist of three parts: dust collection, suction, and filtration. Vacuuming accessories include extended hoses, folding hoses, and telescopic hoses. Folding hoses, with their flexible structure, help users easily clean low areas (such as under sofas and beds) without frequently bending over or adjusting their body posture.

[0003] Before leaving the factory, the folded tube needs to undergo a bending test, which involves bending the folded tube at a certain angle and then inspecting it to check for defects such as cracks on its surface.

[0004] Currently, the bending operation of folded tubes needs to be done manually by operators. That is, the operator sits on one side of the conveyor line, manually bends the folded tubes that are conveyed to him, and then puts them into the testing mechanism for testing. The manual bending method increases the labor intensity of the operators, and different operators have different operating habits and methods, so it is impossible to ensure that the bending angle of the folded tubes is consistent every time, which will affect the accuracy of the subsequent test results. Utility Model Content

[0005] This utility model provides a folding tube bending mechanism for vacuum cleaners, which solves the defect that manual bending of folding tubes cannot guarantee that the bending angle of the folding tube remains consistent each time.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a folding tube bending mechanism for a vacuum cleaner, comprising: A support assembly for supporting the folded tube; A pressing assembly is disposed on one side of the support assembly and presses against the folded tube; A bending assembly is disposed on one side of the supporting assembly and is used to drive the folded tube to rotate between two extreme positions of 0° and 90°.

[0007] Ideally, the supporting component includes a base plate, a fixing plate fixed to the top of the base plate, a clamping plate fixed at intervals to the top of the fixing plate, and a clamping groove formed on the top of the clamping plate, wherein the folded tube is placed in the clamping groove.

[0008] Ideally, the pressing assembly includes a gantry fixed to the top of the base plate and a pressing head that is vertically and flexibly disposed on one side of the gantry, the pressing head abutting against the folded tube.

[0009] Optimally, the bending assembly includes a rotating plate rotatably mounted on the top of the base plate, two connecting plates integrally connected to one side of the rotating plate, a contact wheel mounted on the side of the connecting plate away from the rotating plate, and a receiving groove formed on the outside of the contact wheel.

[0010] Optimally, the bending assembly further includes an extension plate fixed to one side of the gantry frame, a clamping plate fixed at intervals to one side of the extension plate, and a slot formed between the clamping plates. When the folding tube is bent to 90°, the folding tube is inserted into the slot.

[0011] Optimally, the bending assembly further includes a guide portion disposed on the inner side of the card plate and inclined thereon, and an arc-shaped portion disposed on the inner side of the guide portion.

[0012] Optimally, the pressing assembly further includes a first mounting plate fixed to one side of the gantry, a cylinder mounting plate fixed to the top of the first mounting plate, a first reinforcing plate fixed between the first mounting plate and the cylinder mounting plate, and a pressing cylinder fixed to the top of the cylinder mounting plate and connected to the pressing head.

[0013] Optimally, the bending assembly further includes a support plate fixed to the top of the base plate, a third mounting plate fixed to the top of the support plate, a third reinforcing plate fixed between the support plate and the third mounting plate, and a rotary cylinder fixed to one side of the third mounting plate, wherein the rotating plate is fixed to the rotary cylinder.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The folding tube bending mechanism for vacuum cleaners of this utility model first requires the operator to place the folding tube in the clamping groove of the bearing component when bending the folding tube. Then, the pressure head of the pressing component descends and presses against the folding tube. Finally, the bending component bends the folding tube into the slot. This reduces the labor intensity of the operator and ensures that the bending angle of the folding tube is consistent each time, avoiding the influence of human factors on the subsequent test results.

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0017] like Figure 1-3 The diagram shows the structure of the folding tube bending mechanism for a vacuum cleaner according to this utility model. It includes a bearing component, a pressing component, and a bending component. The operator places the folding tube on the bearing component, and the pressing component presses it onto the folding tube. During bending, the folding tube is prevented from tipping over. Finally, the bending component drives the folding tube to rotate and bend between two extreme positions: 0° and 90°.

[0018] The supporting components include a base plate 1, a fixing plate 2, a clamping plate 3, and a clamping groove 4. The base plate 1 is a rectangular metal plate, which is fixed to the testing machine platform by screws. The base plate 1 mainly serves a supporting function. The fixing plate 2 is fixed to the top of the base plate 1 by screws. There are multiple clamping plates 3, which are fixed to the top of the fixing plate 2 by welding. The clamping groove 4 is opened on the top of the clamping plate 3 and the shape of the clamping groove 4 matches the bottom of the folded tube.

[0019] like Figure 1 As shown, during actual bending, the operator places the folded tube in the groove 4 of the clamping plate 3, and then pushes the folded tube until the handle on the bottom side of the folded tube abuts against the leftmost clamping plate 16, thus completing the positioning of the folded tube. By setting multiple sets of clamping plates 16, the stability of the folded tube placement is improved.

[0020] The pressing assembly is located on one side of the supporting assembly. The pressing assembly includes a vertical plate 5, a top plate 6, a first mounting plate 7, a cylinder mounting plate 8, a first reinforcing plate 9, a pressing cylinder 10, and a pressing head 11. There are two vertical plates 5, which are fixed to the top of the base plate 1 by welding. The top plate 6 is fixed to the top of the two vertical plates 5 by welding (the two vertical plates 5 and the top plate 6 form a "U" shape structure, and the opening of the "U" shape structure faces the base plate 1).

[0021] The first mounting plate 7 is fixed to one side of one of the upright plates 5 by screws. The cylinder mounting plate 8 is fixed to the side of the first mounting plate 7 away from the upright plate 5 by welding and is set horizontally. In order to improve the structural strength of the cylinder mounting plate 8 and prevent the cylinder mounting plate 8 from deforming downward, a first reinforcing plate 9 is fixed in the right-angle area between the cylinder mounting plate 8 and the first mounting plate 7. The two right-angled sides of the first reinforcing plate 9 abut against the cylinder mounting plate 8 and the first mounting plate 7 respectively.

[0022] The cylinder body of the pressing cylinder 10 is fixed to the top of the cylinder mounting plate 8 by screws. The piston rod of the pressing cylinder 10 passes through the through hole on the cylinder mounting plate 8 and is fixed to the pressing head 11. The pressing cylinder 10 drives the pressing head 11 to descend until the pressing head 11 presses against the upper wall of the folded tube, thus completing the pressing of the folded tube. This prevents the folded tube from tipping over when bending it later. (A commercially available CDQSB25-125DCM model cylinder can be used for the pressing cylinder 10.)

[0023] The bending assembly includes a second mounting plate 12, an extension plate 13, a second reinforcing plate 14, a clamping plate 16, a clamping groove 17, a guide portion 18, an arc-shaped portion 19, a support plate 20, a third mounting plate 21, a third reinforcing plate 22, a rotary cylinder 23, a rotating plate 24, a connecting plate 25, a fixing rod 26, a contact wheel 27, a receiving groove 28, and a limiting nut 29. Figure 4 As shown, the second mounting plate 12 is fixed to the top plate 6 near the pressing assembly by screws, and the extension plate 13 is fixed to the side of the second mounting plate 12 away from the top plate 6 by welding and is vertically arranged. In order to improve the structural strength of the extension plate 13, a second reinforcing plate 14 is fixed in the right-angle area between the second mounting plate 12 and the extension plate 13. The two right-angled sides of the second reinforcing plate 14 abut against the inner sides of the second mounting plate 12 and the extension plate 13, respectively.

[0024] Two clamping plates 16 are fixed to the side of the extension plate 13 away from the second reinforcing plate 14 by screws and are spaced apart. A groove 17 is formed between the two clamping plates 16. After the folded tube is bent, it rotates into the groove 17 to ensure that the folded tube will not twist to both sides when bent. A guide portion 18 is obliquely formed on the inner side of the two clamping plates 16 to guide the folded tube as it rotates into the groove 17. An arc-shaped portion 19 is provided on the inner side of the guide portion 18 to ensure a smooth connection and avoid leaving scratches on the outer wall of the folded tube.

[0025] like Figure 3 , 5As shown, the support plate 20 is fixed to the top of the base plate 1 by screws, and the third mounting plate 21 is fixed to one side of the support plate 20 by welding. To improve the structural strength of the third mounting plate 21, a third reinforcing plate 22 is fixed in the right-angle area between the support plate 20 and the third mounting plate 21. The two right-angled sides of the third reinforcing plate 22 abut against the inner sides of the support plate 20 and the third mounting plate 21, respectively. The cylinder body of the rotary cylinder 23 is fixed to the side of the third mounting plate 21 away from the third reinforcing plate 22 by screws. A commercially available HRQ series rotary cylinder can be used for the rotary cylinder 23.

[0026] like Figure 5 As shown, the rotating plate 24 is fixed to the rotating part of the rotary cylinder 23 by screws, and the rotary cylinder 23 drives the rotating plate 24 to rotate. There are two connecting plates 25, which are integrally connected to one side of the rotating plate 24 and rotate synchronously with the rotating plate 24. The fixing rod 26 is installed on the side of the connecting plate 25 away from the rotating plate 24 (specifically, the fixing rod 26 is a threaded rod, and the side of the connecting plate 25 away from the rotating plate 24 has a threaded hole, and the threaded rod is installed in the threaded hole of the connecting plate 25 by screwing).

[0027] The contact wheel 27 is mounted on the fixing rod 26. Specifically, the fixing rod 26 includes an integrally connected screw part and a screw head. The outer circumferential surface of the screw part is provided with threads. The screw part is installed in the threaded hole of the connecting plate 25 by screwing. The contact wheel 27 has a through mounting hole along the axial direction. The diameter of the mounting hole is slightly larger than the outer diameter of the screw part, ensuring that the contact wheel 27 can be installed on the screw part and abut against the side of the screw head near the screw part.

[0028] The limiting nut 29 is screwed onto the screw section and abuts against the side of the contact wheel 27 away from the screw head. The limiting nut 29 and the screw head limit the contact wheel 27, preventing it from shifting during bending and causing the folded tube to twist. The receiving groove 28 is formed on the outer circumference of the contact wheel 27. The cross-section of the receiving groove 28 is arc-shaped, which limits the placement of the folded tube and prevents it from shifting to both sides and twisting during bending.

[0029] like Figure 1 , 2 As shown in Figure 5, the lower contact wheel 27 is used to bend the folded tube upwards against it. When the rotary cylinder 23 is reset, another set of contact wheels 27 pushes the bent folded tube to the horizontal position.

[0030] The folding tube bending mechanism for vacuum cleaners of this utility model involves the operator placing the folding tube in the clamping groove 4 of the bearing component, then the pressure head 11 of the pressing component descends and presses against the folding tube, and finally the bending component bends the folding tube into the slot 17. This reduces the labor intensity of the operator and ensures that the angle of each bend of the folding tube is consistent, avoiding the influence of human factors on the subsequent test results.

[0031] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
