Description

Technical Field

[0001] This utility model relates to the field of bicycle frame drying technology, specifically a paint drying device for bicycle frame production. Background Technology

[0002] The bicycle frame is the skeleton and main body of the bicycle. Other parts are also directly or indirectly installed on the frame. After the bicycle frame is painted, a drying device is needed to dry the paint on the surface of the frame.

[0003] In the prior art, a paint drying device for bicycle frame production, with publication number "CN220479210U", uses an inlet motor to drive a threaded rod to rotate, which in turn drives a threaded ring to move. The threaded ring then drives a threaded block to move, which in turn drives a connecting rod to move. The connecting rod then drives a connecting plate to move, which in turn drives a placement plate to move. The placement plate moves the painted bicycle frame, enabling autonomous entry and exit from the drying chamber and preventing paint from sticking to the user.

[0004] However, the above technical solutions and existing technologies have the following drawbacks: Although this drying device can move the frame in and out of the drying chamber autonomously, the frame is placed directly on the placement plate and cannot rotate during the drying process. As a result, the hot air introduced into the drying chamber by the air guide box can only dry the left half of the frame on the placement plate, while the right half of the frame cannot be dried well. Therefore, in actual use, the frame is not dried evenly. Some existing drying devices with rotating drying capabilities require staff to enter the drying chamber to handle the frame, which is inconvenient due to the limited space inside the drying chamber.

A paint collection box 11 is placed on the left side of the upper end face of the positioning base plate 1. The paint collection box 11 can collect the paint dripping from the bicycle frame hanging on the hanging rod 38 to avoid paint pollution of the surrounding ground.

[0017] A drying component 3 is provided on the top of the supporting side plate 2. The drying component 3 is used to rotate and dry the bicycle frame so as to fully dry the paint on the outer surface of the bicycle frame. A protective component 4 is provided on the upper surface of the positioning base plate 1. The protective component 4 can not only protect the bicycle frame during the drying process, but also make it convenient for staff to pick up and put down the bicycle frame after opening.

[0018] The drying assembly 3 includes a hanging tray 31, a transmission rod 32, a low-speed motor 33, an industrial hot air blower 34, an insulation pipe 35, an air guide shell 36, a nozzle 37, a hanging rod 38, and a connecting rod 39. The low-speed motor 33 is installed on the right side of the upper end of the support side plate 2. The low-speed motor 33 is connected to an external control switch through a wire. The speed of the low-speed motor 33 is five revolutions per minute. When working, the low-speed motor 33 can not only drive the transmission rod 32 to rotate at a low speed, but also avoid the bicycle frame from rotating too fast during the drying process, which would cause uncured paint to splash and cause orange peel texture or particle clumping. The transmission end of the low-speed motor 33 is connected to the transmission rod 32, which can support the hanging tray 31. The lower end of the transmission rod 32 is connected to the hanging tray 31. The hanging tray 31, the transmission rod 32, and the connecting rod 39 are all connected by welding. The hanging tray 31 can support multiple connecting rods 39.

[0019] The lower end face of the hanging plate 31 is symmetrically connected to the left and right sides and the front and rear sides with connecting rods 39. The connecting rods 39 are connected to the hanging rods 38 by welding. The connecting rods 39 can support the hanging rods 38. The hanging rods 38 are connected to the lower side of the annular side of the connecting rods 39. The hanging rods 38 match the head tube in the bicycle frame. The hanging rods 38 make it convenient for workers to hang the painted bicycle frame. An industrial hot air fan 34 is installed on the left side of the upper end face of the support side plate 2. The industrial hot air fan 34 is connected to an external control switch through wires. The air outlet of the industrial hot air fan 34 is connected to an insulation pipe 35. A guide shell 36 is fixedly connected to the inner wall of the side plate 2. Multiple nozzles 37 are provided on the right end face of the guide shell 36. The blowing range of the multiple nozzles 37 is larger than the area of ​​the bicycle frame hanging on the hanging rod 38. When the industrial hot air blower 34 is working, it can blow hot air of the required temperature through the heat insulation pipe 35 into the inside of the guide shell 36, so that the guide shell 36 blows the hot air to the right through the multiple nozzles 37 to dry the paint on the outer surface of the bicycle frame. Since the detailed internal structure and working principle of the industrial hot air blower 34 are relatively mature technologies in the existing technology, they will not be described in detail here.

[0020] Example 2: Based on Embodiment 1, in this embodiment, the multi-stage electric hydraulic push rod 43 is controlled to move the protective cover 41 to the right and open. At this time, the space between the protective cover 41 and the supporting side plate 2 will increase, so that the staff can conveniently hang or remove multiple bicycle frames around the hanging plate 31.

[0021] The shielding assembly 4 includes a shield 41, a support vertical plate 42, and a multi-stage electro-hydraulic push rod 43. The support vertical plate 42 is fixedly connected to the right side of the upper end face of the positioning base plate 1. The support vertical plate 42 is connected to the positioning base plate 1 by welding. The support vertical plate 42 can support the multi-stage electro-hydraulic push rod 43. The multi-stage electro-hydraulic push rod 43 is installed on the upper side inside the support vertical plate 42. The multi-stage electro-hydraulic push rod 43 is connected to an external control cabinet through wires. When working, the multi-stage electro-hydraulic push rod 43 can drive the shield 41 to move left and right. The left end of the multi-stage electro-hydraulic push rod 43 is equipped with... Equipped with a protective cover 41, the bicycle frame is protected during the drying process. A guide block 49 is provided on the right side of the lower end face of the protective cover 41. The guide block 49 and the protective cover 41 are an integral structure. A guide groove 48 is provided on the upper end face of the positioning base plate 1, and the guide groove 48 matches the guide block 49. The matching guide groove 48 and guide block 49 prevent the protective cover 41 from shifting or shaking during movement and use. An observation window (shown in the figure) is provided on the front end face of the protective cover 41, which allows staff to observe the internal condition of the protective cover 41 in real time.

[0022] A first sealing strip 44 is adhered to the side of the shield 41, and a second sealing strip 45 is adhered to the upper side of the left end face of the shield 41. Both the first sealing strip 44 and the second sealing strip 45 are made of fluororubber. The first sealing strip 44 and the second sealing strip 45, both made of fluororubber, provide better direct sealing between the shield 41 and the supporting side plate 2 and the positioning base plate 1, preventing exhaust gas during the drying process from escaping to the outside and polluting the surrounding environment through the gaps between the shield 41 and the supporting side plate 2 and the positioning base plate 1. A first sealing groove 46 is provided on the inner wall of the supporting side plate 2 and the upper end face of the positioning base plate 1, and the first sealing groove 46 matches the first sealing strip 44.

A second sealing groove 47 is provided on the upper side of the right end face of the supporting side plate 2, and the second sealing groove 47 matches the second sealing strip 45. The second sealing groove 47 prevents the first sealing strip 44 from shifting during use.

[0023] Working principle: The operator first controls the protective cover 41 to move to the right and open it by using the multi-stage electric hydraulic push rod 43 (reference). Figure 2 Then, the painted bicycle frames can be hung on the hanging rod 38. After hanging, the multi-stage electric hydraulic push rod 43 is controlled to move the protective cover 41 to the left to close it (see reference). Figure 1 Once closed, the industrial hot air blower 34 can be started and operated at the preset temperature. The hot air blower 34 blows hot air into the air guide shell 36 through the insulation pipe 35. The hot air entering the air guide shell 36 is then sprayed outwards through multiple nozzles 37 to dry the bicycle frames on the right. Simultaneously, the low-speed motor 33 is started, causing the hanging plate 31 to rotate at a low speed via the transmission rod 32. The hanging plate 31, through the connecting rods 39 and 38, drives the multiple bicycle frames to rotate at a low speed, ensuring that the hot air from the multiple nozzles 37 thoroughly dries the bicycle frames. During the drying process... The installation of the first sealing strip 44 and the second sealing strip 45 improves the sealing between the cover 41 and the supporting side plate 2 and the positioning base plate 1, preventing exhaust gas generated during the drying process from escaping to the outside and polluting the surrounding environment through the gaps between the cover 41 and the supporting side plate 2 and the positioning base plate 1. After the bicycle frame has been rotated and dried for the required time, the staff first turns off the low-speed motor 33 and the industrial hot air blower 34 respectively, and then controls the multi-stage electric hydraulic push rod 43 to move the cover 41 to the right and open it, so that the space between the cover 41 and the supporting side plate 2 is increased, so that the staff can easily take away multiple dried bicycle frames around the hanging tray 31.
