[0026] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] like Figure 1 As shown, a carbon fiber fabric unloading device in one embodiment of the present invention includes an unloading vehicle body 1, and the unloading vehicle body 1 can realize automatic transportation of carbon fiber fabrics. During the transportation process, the stability of the carbon fiber fabric can be guaranteed to avoid the situation where the carbon fiber fabric is affected by unstable transportation.

[0028] like Figure 1-2 As shown, the unloading vehicle body 1 includes an electric drive wheel 2, and the two ends of the electric drive wheel 2 are respectively fixedly connected with an outer rod 3, and an L-shaped inner rod 4 is slidably connected inside the outer rod 3. A support mechanism 7 is installed on the L-shaped inner rod 4, and the support mechanism 7 is in contact with the carbon fiber fabric roll to hold up the carbon fiber fabric roll. A first automatic telescopic rod 5 is installed between the bottom wall of the outer rod 3 and the L-shaped inner rod 4. The first automatic telescopic rod 5 can push the L-shaped inner rod 4 located inside the outer rod 3, thereby changing the distance between the two support mechanisms 7, so that the unloading vehicle body 1 can adapt to carbon fiber fabric rolls of different widths, so that the unloading vehicle body 1 can adapt to meet the unloading requirements of different types of looms, and improve the applicability of the unloading device.

[0029] like Figure 1 As shown, a plurality of universal wheels 6 are fixedly connected to the lower end of the L-shaped inner rod 4 .

[0030] like Figure 1 to Figure 3 As shown, the unloading device further includes a detection mechanism 14, which can detect the carbon fiber fabric roll, judge the quality of the carbon fiber fabric roll during transportation, and determine the delivery location of the carbon fiber fabric roll according to the detection result of the detection mechanism 14. Specifically, the support mechanism 7 can cause the carbon fiber fabric roll to rotate, and during the rotation of the carbon fiber fabric roll, the detection mechanism 14 can perform a comprehensive detection on the carbon fiber fabric roll to improve the accuracy of the detection result of the carbon fiber fabric roll.

[0031] like Figure 1 to Figure 3 As shown, the support mechanism 7 includes a second automatic telescopic rod 8, the lower end of which is fixedly connected to the L-shaped inner rod 4, and one end of the second automatic telescopic rod 8 away from the L-shaped inner rod 4 is fixedly connected to a mounting seat 9. A second slide groove 901 is provided on the mounting seat 9, and a side plate 10 matching the mounting seat 9 is slidably connected to the mounting seat 9. There are two side plates 10, and the two side plates 10 can limit the position of the carbon fiber fabric roll to avoid displacement of the carbon fiber fabric roll during unloading and transportation. Since the side plates 10 are slidably connected to the mounting seat 9, the distance between the two side plates 10 can be changed according to the size of the carbon fiber fabric roll, thereby improving the applicability of the unloading device.

[0032] Furthermore, if Figure 3 As shown, driving wheels 11 are rotatably connected on opposite surfaces of the two side panels 10, and the driving wheels 11 are located in the middle of the side panels 10. A first motor 12 for driving the driving wheels 11 is fixedly connected to one of the side panels 10, and the first motor 12 is installed on one side of the side panel 10. That is, when both ends of the shaft of the carbon fiber fabric roll are located on the driving wheels 11, by starting the first motor 12, one of the driving wheels 11 can rotate with the carbon fiber fabric roll, and the other driving wheel 11 assists the carbon fiber fabric roll to rotate.

[0033] In order to avoid the carbon fiber fabric roll from being shaken during unloading and transportation, which may affect the physical state of the carbon fiber fabric roll, such as Figure 3As shown, the side plate 10 is also rotatably connected with a lever 13, one end of the lever 13 located between the two side plates 10 is rotatably connected with a pulley 1301, and the other end is rotatably connected with a third automatic telescopic rod 1302, and the end of the third automatic telescopic rod 1302 away from the lever 13 is rotatably connected with the side plate 10. The third automatic telescopic rod 1302 can drive the lever 13 to rotate on the side plate 10. When unloading the roll, the third automatic telescopic rod 1302 makes the lever 13 in a vertical state, in which the carbon fiber fabric roll can fall from top to bottom between the two mounting seats 9. Then, the third automatic telescopic rod 1302 drives the lever 13 to make the pulley 1301 contact with the carbon fiber fabric roll, and the stability of the carbon fiber fabric roll during transportation is ensured by pressing down, and the stability of the carbon fiber fabric roll during rotation can also be ensured.

[0034] like Figure 1-2 As shown, the detection mechanism 14 includes a visual detector 15 and an ultrasonic detector 16. The visual detector 15 detects the carbon fiber fabric roll by appearance detection, and the ultrasonic detector 16 detects the carbon fiber fabric roll by ultrasonic wave during the rotation of the carbon fiber fabric roll.

[0035] Specifically, Figure 1-2 As shown, at least one connecting rod 17 can be detached from the outer rod 3, and an extension rod 18 is installed on the connecting rod 17. A sleeve 19 matching the connecting rod 17 is fixedly connected to one end of the extension rod 18, and the extension rod 18 is sleeved and slidably connected to the connecting rod 17 through the sleeve 19. A bolt 20 is threadedly connected to one side of the sleeve 19, and the bolt 20 contacts the connecting rod 17. By tightening the bolt 20, the friction between the sleeve 19 and the connecting rod 17 is increased, so that the connecting rod 17 and the sleeve 19 are fixed, that is, the extension rod 18 can be fixed on the connecting rod 17. The visual detector 15 and the ultrasonic detector 16 are both installed on the extension rod 18, and the positions of the visual detector 15 and the ultrasonic detector 16 can be changed according to the size of the carbon fiber fabric roll to reduce the error generated in the process of the visual detector 15 and the ultrasonic detector 16 detecting the carbon fiber fabric roll.

[0036] Preferably, the detection mechanism 14 does not necessarily include only the visual detector 15 and the ultrasonic detector 16, and other detection devices capable of detecting the quality of the carbon fiber fabric roll may also be provided, such as infrared detection, tactile detection, etc.

[0037] In actual use, it was found that dust is easily attached to the surface of the carbon fiber fabric roll during transportation, which easily affects the subsequent processing quality of the carbon fiber fabric roll. Even in the subsequent processing process, an additional step of processing impurities on the surface of the carbon fiber fabric roll is required, which greatly reduces the production quality and production efficiency of the carbon fiber fabric roll.

[0038] In order to solve the above problems, Figure 1-2 As shown, a dust prevention mechanism 21 is provided on the unloading vehicle body 1, and the dust prevention mechanism 21 can process dust during the transportation of the carbon fiber fabric roll to prevent dust from adhering to the surface of the carbon fiber fabric roll. Specifically, the dust prevention mechanism 21 includes a first dust suction plate 22, the air inlet of the first dust suction plate 22 is close to the ground, and a cleaning brush 23 is fixedly connected to the air inlet of the first dust suction plate 22, and the cleaning brush 23 can contact the ground and clean impurities on the ground.

[0039] like Figure 1-2 As shown, an air pump 24 is installed on the unloading vehicle body 1, and a first air inlet pipe 25 is installed between the air inlet of the air pump 24 and the first dust suction plate 22. The air inlet of the first dust suction plate 22 can collect impurities cleaned by the cleaning brush 23 by negative pressure, so as to prevent impurities on the ground from affecting the quality of the carbon fiber fabric roll.

[0040] like Figure 1-2 As shown, an exhaust bag 28 is also installed on one side of the L-shaped inner rod 4 located at the support mechanism 7, and a first air outlet pipe 27 is installed between the air pump 24 and the exhaust bag 28. The gas generated by the air pump 24 is provided to the exhaust bag 28 to expand the exhaust bag 28. After the exhaust bag 28 expands, it becomes round. The exhaust bag 28 is continuously inflated, and the exhaust bag 28 can spray out an air curtain, which can completely wrap the carbon fiber fabric roll to prevent dust from adhering to the carbon fiber fabric roll and affecting the production quality of the carbon fiber fabric.

[0041] Specifically, Figure 5 As shown, the exhaust bag 28 includes a first bag body 2801 and a second bag body 2802, and a baffle 2803 is installed between the first bag body 2801 and the second bag body 2802, and the baffle 2803 can connect the first bag body 2801 and the second bag body 2802. When the air pressure in the exhaust bag 28 is too high, a gap will be formed between the baffle 2803 and the second bag body 2802, and the gas in the exhaust bag 28 will be ejected from the gap between the baffle 2803 and the second bag body 2802.

[0042] Since the air inlet of the air pump 24 absorbs dust by means of negative pressure, a filter 26 is provided on the first air inlet pipe 25. The filter 26 can filter the gas in the first air inlet pipe 25 to separate impurities from the gas and prevent the impurities in the gas from adhering to the surface of the carbon fiber fabric roll.

[0043] Preferably, a negative ion generator is installed on the first air outlet pipe 27, that is, the gas entering the exhaust bag 28 is a gas containing negative ions. The negative ion gas is blown to the surface of the carbon fiber fabric roll, which can eliminate the static electricity generated on the surface of the carbon fiber fabric roll, thereby preventing the carbon fiber fabric roll from absorbing dust due to static electricity, and avoiding the situation in which dust adhesion during the transportation of the carbon fiber fabric roll affects the quality of the carbon fiber fabric roll.

[0044] like Figure 1-2 As shown, a shielding airbag 30 opposite to the exhaust bag 28 is installed on the unloading vehicle body 1, and a connecting tube 29 is installed between the exhaust bag 28 and the shielding airbag 30, that is, the shielding airbag 30 is installed at the end away from the exhaust bag 28, that is, the shielding airbag 30 is installed on the other L-shaped inner rod 4, and a space for placing the carbon fiber fabric roll is formed between the exhaust bag 28 and the shielding airbag 30, and this space is isolated from the wind to form an isolated space, thereby preventing dust from entering the isolated space from the outside, thereby preventing dust from adhering to the carbon fiber fabric roll.

[0045] Specifically, the opposite surface of the shielding airbag 30 and the exhaust bag 28 is the arc surface 3001. When the wind curtain blown out by the exhaust bag 28 blows onto the arc surface 3001, the wind will disperse along the direction set by the arc surface 3001. The dispersed wind can blow onto the air pump 24 and the electric drive wheel 2, thereby realizing the heat dissipation of the air pump 24 and the electric drive wheel 2.

[0046] like Figure 1-2 As shown, a dust removal mechanism 31 is also installed on the unloading vehicle body 1. The dust removal mechanism 31 can absorb dust on the surface of the carbon fiber fabric roll, and the dust removal mechanism 31 is also located in the isolation space. The dust removal mechanism 31 realizes dust absorption on the surface of the carbon fiber fabric roll by means of negative pressure. During transportation, the dust on the surface of the carbon fiber fabric roll can be processed to avoid the dust attached to the carbon fiber fabric roll from being brought into the next process to affect the quality of the carbon fiber fabric product.

[0047] Specifically, Figure 1 , Figure 4 As shown, the dust removal mechanism 31 includes two dust removal mechanisms 31, and a first slide groove 401 matching the dust removal mechanism 31 is provided on the opposite surface of the L-shaped inner rod 4, and the dust removal mechanism 31 is slidably connected in the first slide groove 401. A second dust suction plate 33 is rotatably connected between the two sliders 32, and a second air intake pipe 34 is installed between the second dust suction plate 33 and the first air intake pipe 25. The connection end of the first air intake pipe 25 and the air pump 24 is located at the front end of the filter 26, that is, the dust sucked by the negative pressure of the dust removal mechanism 31 is also filtered by the filter 26.

[0048] The second dust collecting plate 33 is slidably connected in the first slide groove 401 through the slider 32, and can be moved according to the outer diameter of the carbon fiber fabric roll to place the second dust collecting plate 33 in the best negative pressure adsorption position. The second dust collecting plate 33 is rotatably connected between the two sliders 32, and according to the sliding position of the slider 32, the second dust collecting plate 33 can be rotated to match the carbon fiber fabric roll.

[0049] When using, Figure 1 As shown, first, the size parameters of the carbon fiber fabric roll need to be provided to the unloading device, and the unloading device adjusts its own size according to the size parameters of the carbon fiber fabric roll. That is, the first automatic telescopic rod 5 in the outer rod 3 pushes the L-shaped inner rod 4 outward or slides the L-shaped inner rod 4 inward to change the width of the unloading device.

[0050] At the same time, the mounting seat 9 slides in the side plate 10, changing the distance between the two side plates 10 so that the side plates 10 can match the carbon fiber fabric roll. The two side plates 10 are responsible for fixing the carbon fiber fabric roll, and the carbon fiber fabric roll is in contact with the driving wheel 11, one of which is driven to rotate by the first motor 12. The carbon fiber fabric roll is detected by the detection mechanism 14 during its rotation.

[0051] When the driving wheel 11 drives the carbon fiber fabric roll to rotate, the third automatic telescopic rod 1302 will drive the lever 13 to rotate, so that the pulley 1301 contacts the carbon fiber fabric roll and provides a downward force to the carbon fiber fabric roll, thereby ensuring that the carbon fiber fabric roll is not easily affected by bumps during transportation and avoiding the situation where the physical state of the carbon fiber fabric roll is affected by the bumps of the carbon fiber fabric roll.

[0052] In addition, during the transportation of the unloading vehicle 1, the cleaning brush 23 will clean the road ahead to deal with the dust on the road ahead of the unloading vehicle 1 to prevent the dust from adhering to the carbon fiber fabric roll. At the same time, the exhaust bag 28 and the shielding air bag 30 cooperate with the wind blown out by the negative pressure of the air pump 24 to provide an isolated space for the carbon fiber fabric roll. The carbon fiber fabric roll is located in the isolated space to prevent dust from affecting the carbon fiber fabric roll.

[0053] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0054] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
