Description

Technical Field

[0001] This utility model relates to the technical field of carbon fiber cloth processing equipment, specifically a carbon fiber cloth drying device. Background Technology

[0002] In the field of badminton racket manufacturing, the drying process of carbon fiber cloth is a key step to ensure the quality of subsequent molding. The dried carbon fiber cloth must have a stable moisture content and extremely high surface cleanliness to ensure the bonding strength with the resin and avoid defects such as bubbles and delamination in the badminton racket frame.

[0003] Currently, most mainstream carbon fiber cloth drying devices in the industry adopt a hot air circulation structure, but they neglect the problem of impurities on the surface of the cloth before drying: during the initial unwinding and cutting process, impurities such as fiber lint and dust are easily left on the surface of the carbon fiber cloth. These impurities will adhere tightly to the surface of the cloth due to the high temperature during drying, and are difficult to remove later. If the impurities enter the molding process with the cloth, it will directly lead to a decrease in the mechanical properties of the badminton racket frame, and even the risk of cracking after molding.

[0004] Existing methods for cleaning impurities have significant limitations: they rely heavily on manual wiping with hand cloths, which is inefficient and can easily damage carbon fiber filaments. This not only increases production process and equipment costs but also easily causes secondary pollution during transportation. Utility Model Content

The distribution box is provided with multiple air outlet pipes inserted into the drying box on one side, and multiple air outlet holes are provided at the lower end of the air outlet pipes. The drying oven is fixedly equipped with a partition, and a cleaning chamber is provided at the front end of the partition. A fixed frame and a sliding groove are provided on one side of the drying oven. The fixed frame is located on one side of the cleaning chamber, and the sliding groove is connected to the cleaning chamber. Two positioning seats are slidably arranged on the fixed frame.

An adhesive cleaning cylinder is provided on the inner side of the slider, which is inserted into the cleaning chamber. An adhesive sleeve is provided on the outer ring of the adhesive cleaning cylinder.

[0007] To make the drying oven cleaner, the present invention is improved by fastening annular frames to the outer end of the air inlet pipe and the upper end of the air outlet pipe. The annular frames are equipped with dustproof nets, and the annular frames are threadedly connected to the air inlet pipe and the air outlet pipe.

[0008] To improve the drying effect of carbon fiber cloth, the present invention includes the following improvement: multiple limiting rollers are symmetrically arranged inside the drying box.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-5 This utility model provides a carbon fiber cloth drying device, including a processing table 1, a drying box 2 fixedly installed at the upper end of the processing table 1, a fan 3 fixedly installed at the lower end of the processing table 1, an exhaust pipe 4 provided at the top of the drying box 2, two diversion boxes 7 symmetrically arranged on one side of the drying box 2, the air outlet of the fan 3 is connected to the diversion box 7 through a conduit 8, and the air inlet of the fan 3 is provided with an air inlet pipe. The distribution box 7 is provided with multiple air outlet pipes 9 inserted into the drying box 2 on one side, and multiple air outlet holes are provided at the lower end of the air outlet pipes 9. The drying oven 2 is fixedly provided with a partition 11. The front end of the partition 11 is provided with a cleaning chamber 12. A fixed frame 13 and a slide 14 are provided on one side of the drying oven 2. The fixed frame 13 is located on one side of the cleaning chamber 12. The slide 14 is connected to the cleaning chamber 12. Two positioning seats 15 are slidably arranged on the fixed frame 13. The inner side of the positioning seat 15 is provided with a slider 23 that passes through the slide 14 and is slidably connected to the slide 14. The inner side of the slider 23 is provided with an adhesive cleaning cylinder 19 that is inserted into the cleaning chamber 12. The outer ring of the adhesive cleaning cylinder 19 is provided with an adhesive sleeve.

[0015] 1. Device initialization and dustproof assembly: The processing table 1 serves as the basic support for the entire device. The upper end of the table is fixed to support the drying box 2, and the lower end is fixed to install the fan 3, forming a stable structure of "lower power - middle processing - upper exhaust".

[0016] 2. Adjustment of the spacing between the adhesive cleaning cylinders (to match fabric thickness): The upper end of the fixed frame 13 is fixedly equipped with a motor 16. The output end of the motor 16 is provided with a rotating shaft 17. The rotating shaft 17 is provided with two threaded rods 18 with reverse thread structure. The two threaded rods 18 pass through two positioning seats 15 respectively and are threadedly connected to the positioning seats 15. Two guide rods passing through the positioning seats 15 are symmetrically arranged on the outer side of the fixed frame 13. The positioning seats 15 are slidably connected to the guide rods.

[0017] Depending on the thickness of the carbon fiber cloth to be processed, the distance between the two adhesive cleaning cylinders 19 is adjusted by the motor 16 at the upper end of the fixing frame 13: the motor 16 is started, and the rotating shaft 17 at the output end of the motor 16 drives the two reverse threaded rods 18 on it to rotate synchronously. Since the two threaded rods 18 pass through the two positioning seats 15 on the fixing frame 13 respectively and form a threaded engagement, and the outer side of the positioning seat 15 is fitted with a guide rod connected to the fixing frame 13 (restricting the positioning seat 15 to move only in a straight line), the rotation of the threaded rods 18 causes the two positioning seats 15 to move closer or further apart along the guide rod.

[0018] The slider 23 inside the positioning seat 15 passes through the slide groove 14 and slides in cooperation with the slide groove 14. The slider 23 moves synchronously with the positioning seat 15, thereby driving the adhesive cleaning cylinder 19 inside the slider 23 (inserted into the cleaning cavity 12) to adjust the spacing until the adhesive sleeves of the outer ring of the two adhesive cleaning cylinders 19 are adapted to the upper and lower surfaces of the carbon fiber cloth to be conveyed (ensuring tight contact and not damaging the cloth).

[0019] A positioning sleeve 21 is rotatably provided on the inner side of the slider 23. A positioning rod 22 is provided at the front end of the adhesive cleaning cylinder 19. The positioning rod 22 is inserted into the positioning sleeve 21 and threadedly connected to the positioning sleeve 21. A bearing 20 is rotatably provided on the inner side of the slider 23. The positioning sleeve 21 passes through the inner ring of the bearing 20 and is interference-fitted with the inner ring of the bearing 20.

[0020] During this process, the bearing 20 inside the slider 23 supports the rotation of the positioning sleeve 21. The positioning sleeve 21 is threadedly connected to the positioning rod 22 at the front end of the adhesive cleaning cylinder 19, ensuring that the adhesive cleaning cylinder 19 remains stable and does not shift during the spacing adjustment.

[0021] 3. Drying of carbon fiber cloth and simultaneous impurity removal: The carbon fiber cloth is fed into the drying chamber 2 through a designated unwinding device. The limiting rollers 10, which are symmetrically arranged inside the drying chamber 2, contact the surface of the cloth to limit the large up and down swing of the carbon fiber cloth during the conveying process and ensure that the cloth always moves smoothly along the preset trajectory.

[0022] The outer end of the air inlet pipe and the upper end of the air outlet pipe 4 are both fitted with a ring frame 5, and the ring frame 5 is provided with a dustproof net 6. The ring frame 5 is threadedly connected to the air inlet pipe and the air outlet pipe 4.

[0023] Multiple limiting rollers 10 are symmetrically arranged inside the drying box 2.

[0024] When the blower 3 is started, it draws in air (filtered by the dust filter 6) through the inlet duct. The heated drying air is then delivered to the two distribution boxes 7 through the duct 8. The distribution boxes 7 evenly distribute the hot air to each outlet duct 9, and finally blow it out from the air outlet at the lower end of the outlet duct 9, directly acting on the upper and lower surfaces of the carbon fiber cloth to achieve all-round and uniform drying. Excess hot air and moisture in the drying chamber 2 are discharged through the exhaust duct 4 at the top. The dust filter 6 at the upper end of the exhaust duct 4 prevents external impurities from flowing back in with the airflow.

[0025] During the fabric conveying process, when the carbon fiber cloth passes through the cleaning chamber 12, its upper and lower surfaces are in close contact with the adhesive sleeves of the outer rings of the two adhesive cleaning cylinders 19.

[0026] As the fabric continues to move, the friction causes the adhesive cleaning cylinder 19 to rotate around the positioning sleeve 21 (the positioning sleeve 21 rotates smoothly under the support of the bearing 20, reducing friction loss). The adhesive sleeve can efficiently adhere to the residual fibers, dust and other impurities on the fabric surface, achieving simultaneous "drying-cleaning".

[0027] Meanwhile, the partition 11 inside the drying chamber 2 can prevent a large amount of hot air from entering the cleaning chamber 12, thus avoiding the impact of high temperature on the adhesion performance of the adhesive sleeve and ensuring a stable impurity cleaning effect.

[0028] 4. Replacement of the adhesive cleaning cartridge (maintenance operation): When there are many impurities adhering to the surface of the adhesive sleeve and the cleaning effect decreases, the adhesive cleaning cylinder 19 needs to be replaced: First, disassemble the connection between the fixing frame 13 and the drying box 2 by screwing, and move the fixing frame 13 together with the positioning seat 15, the slider 23 and the adhesive cleaning cylinder 19 outwards, so that the adhesive cleaning cylinder 19 is separated from the cleaning chamber 12. Then rotate the positioning rod 22 at the front end of the adhesive cleaning cylinder 19. Since the positioning rod 22 is threadedly connected to the positioning sleeve 21 inside the slider 23, the positioning rod 22 can be disassembled from the positioning sleeve 21 after rotation, and the old adhesive cleaning cylinder 19 can be removed.

[0029] When replacing the new adhesive cleaning cylinder 19, simply align the positioning rod 22 of the new cleaning cylinder with the positioning sleeve 21 and tighten it, then reinstall the fixing bracket 13 back onto the outside of the drying box 2, and the slider 23 and the slide groove 14 will re-fit, thus completing the maintenance. The operation is convenient and does not require disassembling the main structure of the drying box 2.

[0030] By relying on the cooperation of motor 16, reverse threaded rod 18 and guide rod, the distance between the two adhesive cleaning cylinders 19 can be flexibly adjusted: motor 16 drives threaded rod 18 to precisely control the movement of positioning seat 15, guide rod limits the offset of positioning seat 15, slider 23 and slide groove 14 ensure stable movement trajectory of adhesive cleaning cylinder 19, which can adapt to carbon fiber cloth of different thicknesses (from thin to thick, it can achieve close contact cleaning), without the need to replace special cleaning parts, improve the versatility of the device, and meet the processing needs of different specifications of carbon fiber cloth in badminton racket processing.

[0031] The limiting roller 10 inside the drying chamber 2 restricts the swing of the fixed carbon fiber cloth, ensuring smooth cloth conveying and allowing hot air to act evenly on the cloth surface, avoiding incomplete drying in some areas; the adhesive cleaning cylinder 19 rotates smoothly and the spacing is precisely adjusted through the cooperation of the positioning sleeve 21, positioning rod 22 and bearing 20, ensuring that the cloth is subjected to uniform force during the cleaning process and that no wrinkles or damage occur.

[0032] The hot air delivery system consisting of fan 3, duct 8, and distribution box 7 can achieve uniform distribution of hot air. The multiple air outlets of the air outlet pipe 9 ensure that the upper and lower surfaces of the fabric are heated simultaneously, significantly improving drying efficiency compared to traditional single-sided drying equipment. The synchronous cleaning function eliminates the need for subsequent manual wiping, greatly shortening the processing time of a single piece of fabric. It can meet the batch production needs of badminton racket processing and improve the overall production rhythm.
