Description

Technical Field

[0001] This utility model relates to the field of carbon fiber frame coating technology, and more specifically, to a carbon fiber frame coating equipment. Background Technology

[0002] Carbon fiber bicycles are mainly mid-to-high-end racing bicycles. As an emerging material, carbon fiber is mainly used in frames (carbon frames), forks, wheelsets (carbon rims), etc. In the production of carbon fiber frames, in order to ensure their aesthetics and corrosion resistance, they usually need to be sprayed, which requires the use of coating equipment.

[0003] Existing painting equipment is usually handheld or fixed, which can easily lead to uneven coating of carbon fiber frames, thus affecting the coating quality. Therefore, we propose a carbon fiber frame painting equipment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a carbon fiber frame coating equipment to solve the technical problem of poor coating effect of the current coating equipment.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a carbon fiber frame coating equipment, including a shell, a partition arranged in the center of the shell, a channel opened in the center of the partition, the shell is divided into a hanging area and a spraying area by the partition, a drive structure is arranged at the top of the shell, and a hanging structure is arranged at the bottom of the drive structure, two sets of symmetrical spraying structures are arranged in the spraying area at the channel position, a storage box is arranged at the top of the shell, and a conveying pump is arranged at the rear side of the storage box at the top of the shell;

[0006] The mounting structure includes a triangular shell, a first top fixing rod, a second top fixing rod, and a third top fixing rod. The first top fixing rod is movably arranged at the apex of the triangular shell, the second top fixing rod is movably arranged at one bottom corner of the triangular shell, and the third top fixing rod is movably arranged at the other bottom corner of the triangular shell. The bottom of the first top fixing rod is rotatably arranged with guide rods on both sides inside the triangular shell. The two sets of guide rods are rotatably connected to the corresponding second and third top fixing rods, respectively. A return spring is arranged between the bottom end of the first top fixing rod and the bottom inside the triangular shell.

[0007] This invention divides the interior of the outer shell into a hanging area and a spraying area using a partition. A drive structure is arranged at the top of both the hanging and spraying areas. The spraying structure is located in the channel near the partition in the spraying area. Therefore, when spraying the carbon fiber bicycle frame, the frame can be directly hung and fixed to the hanging structure in the hanging area. The drive structure then moves the frame towards the spraying area. As the frame moves, the spraying structure provides continuous dynamic spraying, ensuring uniform coating. Once the frame has completely passed through the spraying structure, the first coat is complete. As the frame moves from the partition channel into the hanging area, the spraying structure performs a second coat, resulting in multiple uniform coats and improved coating quality. The hanging structure of this invention utilizes a triangular shell... The structure consists of a body, a first top fixing rod, a second top fixing rod, a third top fixing rod, a transmission rod, and a return spring. Therefore, when mounting the carbon fiber bicycle frame, the mounting structure extends into the triangular frame of the carbon fiber bicycle frame. At this time, the top of the first top fixing rod rests against the apex of the triangular frame of the carbon fiber bicycle frame. Then, under the weight of the carbon fiber bicycle frame, the first top fixing rod moves into the triangular shell. With the cooperation of the transmission rod, the second and third top fixing rods at the bottom two corners of the triangular shell are pushed outwards. The second and third top fixing rods then rest against the bottom two corners of the triangular frame of the carbon fiber bicycle frame. Therefore, the first, second, and third top fixing rods can automatically support the triangular frame of the carbon fiber bicycle frame, thus achieving a stable mounting of the carbon fiber bicycle frame, ensuring stability during displacement, and preventing shaking or displacement during the painting process, which could affect the uniformity of the paint coating. This further ensures the painting effect of the carbon fiber bicycle frame.

[0008] Preferably, the spraying structure includes a spraying assembly and an adjusting frame. The adjusting frame is arranged on the inner wall of the spraying area, and the spraying assembly is arranged on the adjusting frame. The spraying assembly includes a first spraying pipe, a second spraying pipe, a third spraying pipe, a fourth spraying pipe, and a fifth spraying pipe. The first spraying pipe, the second spraying pipe, the third spraying pipe, the fourth spraying pipe, and the fifth spraying pipe are arranged sequentially from front to back. Several sets of equidistant atomizing nozzles are arranged on the first spraying pipe, the second spraying pipe, the third spraying pipe, the fourth spraying pipe, and the fifth spraying pipe.

[0009] Preferably, the drive structure includes a mounting shell arranged inside an outer shell. A lead screw is rotatably arranged inside the mounting shell. A first motor is arranged at one end of the mounting shell, and the rotation shaft at the output end of the first motor is connected to one end of the lead screw. A mounting block is arranged on the lead screw, and a connecting rod is arranged at the bottom of the mounting block.

[0010] Preferably, a rectangular rod is arranged on the triangular shell, and the rectangular rod is connected to the connecting rod. The first top fixing rod, the second top fixing rod, and the third top fixing rod are arranged with an arc-shaped top frame at the outer end of the triangular shell.

[0011] Preferably, the adjustment frame includes a rectangular frame arranged on the inner wall of the spraying area, and telescopic frames are arranged at the top and bottom of one side of the rectangular frame, and an electro-hydraulic push rod is arranged inside the telescopic frame.

[0012] Preferably, the telescopic frame includes a concave sleeve rod, an insert rod, and a welding plate. The concave sleeve rod is arranged on a rectangular frame, and the insert rod is located inside the concave sleeve rod. The welding plate is arranged at one end of the insert rod. The electro-hydraulic push rod cylinder is arranged on the rectangular frame. The piston end of the electro-hydraulic push rod is connected to the welding plate. The first spray pipe, the second spray pipe, the third spray pipe, the fourth spray pipe, and the fifth spray pipe are arranged between the welding plates of the two sets of telescopic frames.

[0013] Preferably, the atomizing nozzles on the first spray pipe are arranged horizontally, the atomizing nozzles on the second spray pipe are arranged obliquely backward, the atomizing nozzles on the third spray pipe are arranged obliquely downward, the atomizing nozzles on the fourth spray pipe are arranged obliquely forward, and the atomizing nozzles on the fifth spray pipe are arranged obliquely upward. The input end of the delivery pump is connected to the output end of the storage tank through a conduit, and the output end of the delivery pump is connected to the first, second, third, fourth, and fifth spray pipes through a conduit.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model divides the interior of the outer shell into a hanging area and a spraying area using a partition. A drive structure is arranged at the top of both the hanging and spraying areas. The spraying structure is located in the channel near the partition in the spraying area. Therefore, when spraying carbon fiber bicycle frames, the carbon fiber bicycle frame can be directly hung and fixed to the hanging structure in the hanging area. Then, the drive structure is controlled to move the carbon fiber bicycle frame on the hanging structure towards the spraying area. As the carbon fiber bicycle frame moves into the spraying area, the spraying structure can achieve a continuous dynamic spraying effect on the carbon fiber bicycle frame, ensuring the coating of the carbon fiber. The present invention improves the uniformity of carbon fiber bicycle frame coating. After the carbon fiber bicycle frame completely passes through the coating structure in the coating area, the first coating is completed. As the coated frame enters the hanging area through the partition, the coating structure performs a second coating, thus achieving multiple uniform coatings and better ensuring the coating quality. This solves the technical problem of poor coating effect in current coating equipment. Therefore, this invention has the advantage of achieving better coating results for carbon fiber bicycle frames.

[0016] 2. The mounting structure of this utility model consists of a triangular shell, a first top fixing rod, a second top fixing rod, a third top fixing rod, a transmission rod, and a return spring. Therefore, when mounting a carbon fiber bicycle frame, the mounting structure extends into the triangular frame of the carbon fiber bicycle frame. At this time, the top of the first top fixing rod rests against the apex of the triangular frame of the carbon fiber bicycle frame. Then, under the weight of the carbon fiber bicycle frame, the first top fixing rod moves into the triangular shell. With the cooperation of the transmission rod, the second and third top fixing rods at the bottom two corners of the triangular shell are pushed outwards. The second and third top fixing rods then rest against the bottom two corners of the triangular frame of the carbon fiber bicycle frame. Therefore, the first, second, and third top fixing rods can automatically support the triangular frame of the carbon fiber bicycle frame, thus achieving stable mounting of the carbon fiber bicycle frame, ensuring stability during displacement, and preventing shaking or displacement during the painting process, which could affect the uniformity of the paint coating. This further ensures the painting effect of the carbon fiber bicycle frame. Attached Figure Description

[0025] like Figures 1 to 6 As shown, the present invention relates to a carbon fiber vehicle frame coating equipment, including a housing 1, a partition 101 arranged in the center of the housing 1, a channel 102 opened in the center of the partition 101, the housing 1 being divided into a hanging area 103 and a spraying area 104 by the partition 101, a drive structure 2 arranged at the top of the housing 1, and a hanging structure 3 arranged at the bottom of the drive structure 2, two sets of symmetrical spraying structures 4 arranged in the spraying area 104 at the position of the channel 102, a storage box 5 arranged at the top of the housing 1, and a conveying pump 6 arranged at the rear side of the storage box 5 at the top of the housing 1.

[0026] When spraying carbon fiber bicycle frames, the carbon fiber bicycle frame can be directly hung and fixed on the hanging structure 3 in the hanging area 103. Then, the drive structure 2 is controlled to move the carbon fiber bicycle frame on the hanging structure 3 towards the spraying area 104. At this time, the delivery pump 6 is controlled to deliver the paint in the storage tank 5 to the spraying structure 4. As the carbon fiber bicycle frame moves into the spraying area 104, the spraying structure 4 can achieve a continuous dynamic spraying effect on the carbon fiber bicycle frame, ensuring the uniformity of the spraying. When the carbon fiber bicycle frame has completely passed through the spraying structure 4 in the spraying area 104, the first spraying effect of the carbon fiber bicycle frame is completed. When the carbon fiber bicycle frame after the first spraying enters the hanging area 103 from the channel 102 of the partition 101, the spraying structure 4 will complete the second spraying effect of the carbon fiber bicycle frame, thereby completing multiple uniform sprayings of the carbon fiber bicycle frame and better ensuring the spraying quality of the carbon fiber bicycle frame.

[0027] Furthermore, the drive structure 2 includes a mounting shell 201, which is arranged inside the outer shell 1. A lead screw 202 is rotatably arranged inside the mounting shell 201. A first motor 204 is arranged at one end of the mounting shell 201, and the rotation shaft of the output end of the first motor 204 is connected to one end of the lead screw 202. A mounting block 203 is arranged on the lead screw 202, and a connecting rod 205 is arranged at the bottom of the mounting block 203. The first motor 204 is controlled to drive the lead screw 202 to rotate, and the mounting block 203 on the lead screw 202 drives the carbon fiber bicycle frame hanging on the hanging structure 3 to move back and forth through the connecting rod 205.

[0028] In an embodiment of this utility model, the hanging structure 3 includes a triangular shell 301, a first top fixing rod 302, a second top fixing rod 303, and a third top fixing rod 304. The first top fixing rod 302 is movably arranged at the apex of the triangular shell 301, the second top fixing rod 303 is movably arranged at one bottom corner of the triangular shell 301, and the third top fixing rod 304 is movably arranged at the other bottom corner of the triangular shell 301.

A rectangular rod 308 is arranged on the triangular shell 301 and is connected to the connecting rod 205. An arc-shaped top frame 305 is arranged on the outer end of the first top fixing rod 302, the second top fixing rod 303 and the third top fixing rod 304.

[0029] When mounting the carbon fiber bicycle frame, the mounting structure 3 extends into the triangular frame of the carbon fiber bicycle frame. At this time, the arc-shaped top bracket 305 of the first top fixing rod 302 supports the apex corner of the triangular frame of the carbon fiber bicycle frame. Then, under the action of the weight of the carbon fiber bicycle frame, the first top fixing rod 302 moves into the triangular housing 301. At this time, the return spring 307 is compressed. With the cooperation of the transmission rod 306, the second top fixing rod 303 and the third top fixing rod 304 at the bottom two corners of the triangular housing 301 are pushed outward. At this time, the second top fixing rod 303 and the third top fixing rod 304 The arc-shaped top brackets 305 are respectively positioned at the two bottom corners of the triangular frame of the carbon fiber bicycle frame. Therefore, the first top fixing rod 302, the second top fixing rod 303, and the third top fixing rod 304 can automatically support the triangular frame of the carbon fiber bicycle frame, thereby achieving a stable mounting of the carbon fiber bicycle frame, ensuring the stability of the carbon fiber bicycle frame during displacement, and preventing the carbon fiber bicycle frame from shaking or shifting during the painting process, which would affect the uniformity of the carbon fiber bicycle frame painting. This further ensures the painting effect of the carbon fiber bicycle frame.

[0031] The distance between the first spray pipe 701, the second spray pipe 702, the third spray pipe 703, the fourth spray pipe 704, and the fifth spray pipe 705 and the carbon fiber bicycle frame can be adjusted via the adjusting bracket 8. Then, the first spray pipe 701, the second spray pipe 702, the third spray pipe 703, the fourth spray pipe 704, and the fifth spray pipe 705 spray the carbon fiber bicycle frame through the atomizing nozzle 706. The horizontally positioned atomizing nozzle 706 on the first spray pipe 701 can perform horizontal spraying on the carbon fiber bicycle frame, the backward-sloping atomizing nozzle 706 on the second spray pipe 702 can perform backward-sloping spraying on the carbon fiber bicycle frame, and the upward-sloping atomizing nozzle 706 on the third spray pipe 703... The downward-angled atomizing nozzle 706 can spray the carbon fiber bicycle frame downwards at an angle. The forward-angled atomizing nozzle 706 on the fourth spray pipe 704 can spray the carbon fiber bicycle frame forwards at an angle. The upward-angled atomizing nozzle 706 on the fifth spray pipe 705 can spray the carbon fiber bicycle frame upwards at an angle. Therefore, with the cooperation of the atomizing nozzles 706 in different directions on the first spray pipe 701, the second spray pipe 702, the third spray pipe 703, the fourth spray pipe 704, and the fifth spray pipe 705, a complete all-round spraying effect on the carbon fiber bicycle frame can be achieved, further ensuring the spraying quality of the carbon fiber bicycle frame.

[0032] Specifically, the adjusting frame 8 includes a rectangular frame 9, which is arranged on the inner wall of the spraying area 104. Telescopic frames 10 are arranged at the top and bottom of one side of the rectangular frame 9, and an electro-hydraulic push rod 11 is arranged inside the telescopic frame 10. The telescopic frame 10 includes a concave sleeve 1001, an insert rod 1002, and a welding plate 1003. The concave sleeve 1001 is arranged on the rectangular frame 9, and the insert rod 1002 is located inside the concave sleeve 1001.

With the cooperation of the concave sleeve rod 1001 and the insert rod 1002, the telescopic frame 10 can extend and retract. Then, the electric hydraulic push rod 11 can drive the welding plate 1003 to move, that is, the positions of the first spray pipe 701, the second spray pipe 702, the third spray pipe 703, the fourth spray pipe 704, and the fifth spray pipe 705 can be adjusted.

[0033] Working Principle: This embodiment provides a carbon fiber bicycle frame coating equipment. First, when spraying the carbon fiber bicycle frame, the carbon fiber bicycle frame can be directly hung and fixed on the hanging structure 3 in the hanging area 103. Then, the drive structure 2 is controlled to move the carbon fiber bicycle frame on the hanging structure 3 towards the spraying area 104. At this time, the delivery pump 6 is controlled to deliver the paint in the storage tank 5 to the spraying structure 4. As the carbon fiber bicycle frame moves into the spraying area 104, the spraying structure 4 can achieve a continuous dynamic spraying effect on the carbon fiber bicycle frame, ensuring the uniformity of the spraying. When the carbon fiber bicycle frame has completely passed through the spraying structure 4 in the spraying area 104, the first spraying effect of the carbon fiber bicycle frame is completed. When the carbon fiber bicycle frame after the first spraying enters the hanging area 103 from the channel 102 of the partition 101, the spraying structure 4 will complete the second spraying effect of the carbon fiber bicycle frame, thereby completing multiple uniform sprayings of the carbon fiber bicycle frame and better ensuring the spraying quality of the carbon fiber bicycle frame.

[0034] Secondly, when mounting the carbon fiber bicycle frame, the mounting structure 3 is inserted into the triangular frame of the carbon fiber bicycle frame. At this time, the arc-shaped top bracket 305 of the first top fixing rod 302 is held against the apex corner of the triangular frame of the carbon fiber bicycle frame. Then, under the action of the weight of the carbon fiber bicycle frame, the first top fixing rod 302 is moved into the triangular shell 301. At this time, the return spring 307 is compressed. With the cooperation of the transmission rod 306, the second top fixing rod 303 and the third top fixing rod 304 at the bottom two corners of the triangular shell 301 are pushed outward. At this time, the second top fixing rod 303 and the third top fixing rod 304... The arc-shaped top bracket 305 of 04 will be placed on the two bottom corners of the triangular frame of the carbon fiber bicycle frame. Therefore, the first top fixing rod 302, the second top fixing rod 303, and the third top fixing rod 304 can automatically fix the triangular frame of the carbon fiber bicycle frame, thereby achieving a stable hanging of the carbon fiber bicycle frame, ensuring the stability of the carbon fiber bicycle frame during displacement, and avoiding shaking or displacement during the movement and spraying of the carbon fiber bicycle frame, which would affect the uniformity of the carbon fiber bicycle frame spraying, thus further ensuring the spraying effect of the carbon fiber bicycle frame.

[0035] Finally, the distance between the first spray pipe 701, the second spray pipe 702, the third spray pipe 703, the fourth spray pipe 704, and the fifth spray pipe 705 and the carbon fiber bicycle frame can be adjusted via the adjusting bracket 8. Then, the first spray pipe 701, the second spray pipe 702, the third spray pipe 703, the fourth spray pipe 704, and the fifth spray pipe 705 spray the carbon fiber bicycle frame through the atomizing nozzle 706. The horizontally positioned atomizing nozzle 706 on the first spray pipe 701 can perform horizontal spraying on the carbon fiber bicycle frame, and the backward-sloping atomizing nozzle 706 on the second spray pipe 702 can perform backward-sloping spraying on the carbon fiber bicycle frame. The third spray pipe 703... The upward-tilting downward-facing atomizing nozzle 706 can spray the carbon fiber bicycle frame downwards, the forward-tilting forward-facing atomizing nozzle 706 on the fourth spray pipe 704 can spray the carbon fiber bicycle frame forwards, and the upward-tilting upward-facing atomizing nozzle 706 on the fifth spray pipe 705 can spray the carbon fiber bicycle frame upwards. Therefore, with the cooperation of the atomizing nozzles 706 in different directions on the first spray pipe 701, the second spray pipe 702, the third spray pipe 703, the fourth spray pipe 704, and the fifth spray pipe 705, a complete all-round spraying effect on the carbon fiber bicycle frame can be achieved, further ensuring the spraying quality of the carbon fiber bicycle frame.
