Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carbon fiber tube surface spraying, in particular to a cooling device. Background Art
[0002] Carbon fiber tubes are also called carbon fiber tubes, carbon fiber tubes, and carbon fiber tubes. They are made of carbon fiber composite materials pre-impregnated with styrene-based polyester resin and then heated, cured, and pulled (wound). During the manufacturing process, various profiles can be produced through different molds, such as: carbon fiber round tubes of different specifications, square tubes of different specifications, sheets of different specifications, and other profiles: 3K can also be wrapped in the production process for surface packaging and beautification, etc.
[0003] In the production process of carbon fiber tubes, plasma spraying operation is required. During the plasma spraying process, the surface temperature of the workpiece continues to rise. In summer, the temperature inside and outside the spraying room is high. If the heat dissipation is not timely, the temperature of the carbon fiber tube workpiece is too high, the resin fails at high temperature, causing the carbon tube to crack and the spraying to fail.
[0004] At present, air suction ports are added to the spray room to improve indoor air circulation and replace indoor hot air. However, the temperature of the plasma spray room is relatively high in summer, which causes the air temperature in the spray room to not drop. The temperature of the carbon tube is still high during the spraying process and needs to be cooled for a period of time before spraying can continue, affecting the spraying efficiency. If the spraying time is too long, untimely cooling will cause the carbon tube to crack at high temperature, resulting in spraying failure. In order to effectively reduce the temperature of the spray room, it is necessary to replace a more powerful compressor, which will increase the energy consumption of the plant and have a high cost.
[0005] Therefore, a cooling device is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-Figure 3 The present embodiment provides a cooling device, comprising: an air suction hood 1 arranged on a workpiece turntable, a connecting pipe 2, a slot 3 for placing the workpiece turntable, a shell 4, two clamping members 5 for clamping the air suction hood 1 on the workpiece turntable, and an adjusting member 6 for adjusting the distance between the two clamping members 5, one end of the connecting pipe 2 is connected to the rear side of the air suction hood 1, and the other end of the connecting pipe 2 is connected to the end of the air suction port of the spraying room, the slot 3 is opened at the bottom of the air suction hood 1, the shell 4 is horizontally fixedly connected to the bottom of the inner cavity of the air suction hood 1, the two clamping members 5 are symmetrically and movably arranged on the front side of the shell 4, and the adjusting member 6 is arranged in the inner cavity of the shell 4.
[0025] Among them, the connecting pipe 2 and the air suction port are detachably connected by screws, so that when the outdoor temperature is low or other workpieces are sprayed, the suction hood 1 and the connecting pipe 2 can be removed from the air suction port and can be installed again when needed next time. The connecting pipe 2 adopts a folding tube. The folding tube can not only reduce the space occupied by the connecting pipe 2 after the cooling device is removed, but also adjust the position of the suction hood 1 according to the position of the workpiece turntable, and has a wider applicability.
[0026] Among them, the clamping part 5 includes a clamping plate 51, and the inner wall surface of the clamping plate 51 is glued with a rubber pad 52. When the two rubber pads 52 are in contact with the side surfaces of the workpiece turntable respectively, the suction hood 1 can be fixed on the workpiece turntable, which not only ensures the stability of the suction hood 1 during the subsequent carbon tube spraying operation, but also facilitates the subsequent disassembly and assembly of the suction hood 1 and the workpiece turntable.
[0027] Among them, the clamping plate 51 and the rubber pad 52 are both inverted L-shaped structures, the top surface of the inner wall of the rubber pad 52 can contact the top of the workpiece turntable, and the side surface of the inner wall of the rubber pad 52 can contact the side surface of the workpiece turntable, which can further limit the downward movement of the suction hood 1 on the workpiece turntable due to gravity, and help to improve the stability of the suction hood 1 fixed on the workpiece turntable.
[0028] Among them, the adjusting member 6 includes a bidirectional screw 61 which is rotatably connected to one side of the inner wall of the shell 4 through a bearing, and a screw sleeve 62 is threadedly sleeved on both sides of the surface of the bidirectional screw 61. A slider 63 is fixedly connected to the surface of the screw sleeve 62. The side of the slider 63 away from the screw sleeve 62 is movable and penetrates to the outside of the shell 4 and is fixedly connected to the corresponding clamping plate 51. By rotating the bidirectional screw 61, the two clamping plates 51 can be driven to move toward or away from each other, and then the spacing between the two clamping plates 51 can be adjusted, which can not only realize the clamping or disassembly operation of the suction hood 1, but also can be suitable for workpiece turntables of different sizes, and has the advantage of a wide range of applications.
[0029] Among them, a sliding hole 64 for the slider 63 to move is opened on the surface of the shell 4, and the inner wall surface of the sliding hole 64 is slidably connected to the slider 63. The sliding hole 64 can provide a movable space for the slider 63 to ensure that the slider 63 can move normally, and can also limit the slider 63, so that the slider 63 can stably move horizontally along the axial direction of the bidirectional screw 61.
[0030] Among them, one end of the bidirectional screw 61 away from the bearing movably penetrates to the outside of the air suction hood 1 and is fixedly connected with a knob 65. The surface of the bidirectional screw 61 is rotatably connected to the shell 4 and the penetration point of the air suction hood 1 through the bearing, respectively. The knob 65 is used to facilitate the staff to rotate the bidirectional screw 61 with force on their hands.
[0031] Among them, a folding curtain 7 is provided on both sides of the inner cavity of the sliding hole 64, and the two sides of the folding curtain 7 are respectively fixedly connected to the corresponding surface of the slider 63 and one side of the inner wall of the sliding hole 64, and the top and bottom of the folding curtain 7 are respectively slidably connected to the inner wall of the corresponding sliding hole 64. The folding curtain 7 can not only ensure that the slider 63 can slide in the inner cavity of the sliding hole 64, but also play a shielding role for the sliding hole 64, so as to prevent the paint from entering the inner cavity of the shell 4 through the sliding hole 64 during the spraying operation and affecting the subsequent use of the bidirectional screw 61.
[0032] The working principle of the utility model is: the workpiece turntable is covered by the air suction cover 1, so that the workpiece turntable is placed in the slot hole 3, and the top surface of the inner wall of the rubber pad 52 is placed on the top of the workpiece turntable, and the knob 65 is turned, and the knob 65 drives the bidirectional screw 61 to rotate. Under the action of the thread, the bidirectional screw 61 drives the two screw sleeves 62 on its surface to move toward each other, and the screw sleeve 62 drives the slider 63 to slide in the inner cavity of the sliding hole 64. The folding curtain 7 in the inner cavity of the sliding hole 64 is contracted or stretched by force, and the slider 63 drives the clamping plate 51 and the rubber pad 52 to rotate. The rubber pad 52 moves synchronously, so that the two clamping plates 51 and the rubber pad 52 move toward each other until the side of the inner wall of the rubber pad 52 contacts the side of the workpiece turntable, thereby completing the connection operation of the suction hood 1 and the workpiece turntable, and finally connecting the connecting pipe 2 to the end of the suction port by screws to complete the installation operation of the cooling device; during the spraying operation, the compressor used in conjunction with the suction port works to form a negative pressure at the suction port, so that the hot air around the carbon tube can be sucked away through the suction hood 1 to reduce the temperature of the workpiece.
[0033] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
