[0024] The suction device 4 can specifically be a water pump, and the heating medium can be water or oil; the heating medium is heated in the heating box 2 through a heating pipe, and the heating temperature of the heating medium is adjusted by a specific control panel of the heating box 2.

[0025] To better understand this solution, the following will further optimize the structure.

[0026] As Figure 2 、 Figure 3 and Figure 4 shown, according to another embodiment of the present utility model, the drying room for a workpiece paint surface, wherein the drying room body 1 includes a main frame 11 and a door 12, the main frame 11 is connected to the ground 5 and has a drying chamber therein, the main frame 11 has two open ends arranged opposite to each other, both open ends are communicated with the drying chamber, and the circulation pipe 3 is arranged inside the main frame 11; there are two doors 12 and they are respectively connected to the two open ends in one-to-one correspondence.

[0027] Specifically, in this embodiment, the longitudinal section of the main frame body 11 is inverted "U", and the ground 5 serves as the bottom wall of the drying chamber body 1. The positions of the two openings facilitate pushing the workpiece into the drying chamber from one opening and removing the workpiece from the other opening after drying. During the drying process, the two doors 12 are used to seal the two openings respectively, so that the drying chamber is a sealed space, which is conducive to quickly drying the workpiece. An exhaust port can also be opened at the top of the main frame body 11 to facilitate discharging the water vapor generated during the drying process.

[0028] Among them, a guiding chute 6 is formed on the ground 5 along the direction of the connection line of the two openings, and a conveying frame 7 slidably connected to the guiding chute 6 is slidably arranged in the drying chamber. The workpiece is placed on the conveying frame 7, and the sliding of the conveying frame 7 is guided by the guiding chute 6 to stably send the workpiece into the drying chamber for drying treatment or remove the dried workpiece from the drying chamber.

[0029] Here, taking the ground 5 as the bottom wall of the drying chamber body 1, on the one hand, the cost of the drying chamber body 1 is reduced, and on the other hand, after arranging the guiding chute 6, the movement of the conveying frame 7 is relatively smooth and will not be hindered.

[0030] Based on the above scheme:

[0031] There are two guiding chutes 6, which are arranged at intervals along the perpendicular direction of the connection line of the two openings. The conveying frame 7 includes a support table 71, a front rolling support member, and a rear rolling support member 72. Among them, the front rolling support member is rotatably connected to the front side of the bottom of the support table 71 and cooperates with the two guiding chutes 6, and the rear rolling support member 72 is rotatably connected to the rear side of the bottom of the support table 71 and cooperates with the two guiding chutes 6.

[0032] In this embodiment, the conveying frame 7 is mainly composed of a support table 71, a front rolling support member, and a rear rolling support member 72. Its structure is simple, and it cooperates with the two guiding chutes 6 for guiding to stably send the workpiece placed on the top surface of the support table 71 into the drying chamber or remove it from the drying chamber. Among them, the top surface of the support table 71 is in a "U" shape, so that there are protections on both sides of the top surface of the support table 71, improving the stability during the transportation of the workpiece.

[0033] Further, a driving part 73 is cooperatively arranged with the front rolling support member or the rear rolling support member 72. In this embodiment, the driving part 73 is connected to the rolling support member, and the driving part 73 provides power to control the rotation of the rear rolling support member 72, and then drives the front rolling support member to rotate, so that the conveying frame 7 moves into or out of the drying chamber along the guiding chute 6.

[0034] Among them, the front rolling support and the rear rolling support 72 have the same structure and both include a rotating shaft 721 and a roller 722. The rotating shaft 721 is provided with a plurality of connecting seats fixedly connected to the bottom of the support platform 71 at intervals along its axial direction. The rotating shaft 721 is rotatably connected to each connecting seat; there are two rollers 722, and the rotating shaft 721 is connected between the two rollers 722. The bottoms of the two rollers 722 roll in the two guiding chutes 6 one by one. In this embodiment, the number of connecting seats is two to stably connect between the rotating shaft 721 and the support platform 71; the front rolling support and the rear rolling support 72 are both composed of a rotating shaft 721, a roller 722 and a connecting seat, and their structures are simple and can meet the use requirements.

[0035] Specifically, the driving part 73 is connected to the rotating shaft 721 in the rear rolling support 72 to drive the rotating shaft 721 to rotate, thereby driving the roller 722 to rotate, and further driving the conveying frame 7 to move. The driving part 73 can be a motor coaxially connected to one end of the rotating shaft 721, or can include a protective cover, a motor and two bevel gears. The protective cover is fixedly arranged at the bottom of the support platform 71, the motor is installed in the protective cover, and the two bevel gears are engaged. One of the bevel gears is connected to the output shaft of the motor, and the other bevel gear is fixedly sleeved on the corresponding rotating shaft 721 and both ends of the rotating shaft 721 freely pass through the protective cover to make the rotation of the rotating shaft 721 more stable. This is the preferred driving part 73 in this embodiment.

[0036] As Figures 3 - 6 As shown, according to another embodiment of the present invention, for the drying room for the workpiece paint surface, each of the doors 12 includes two door panels 121 rotatably arranged at the corresponding openings and arranged in a split manner. An adjustable locking and sealing member 8 is arranged between the two door panels 121. The adjustable locking and sealing member 8 is used for limiting when the two door panels 121 are closed and embedding into the guiding chute 6 for sealing.

[0037] After the workpiece is placed on the support platform 71 and moved into the drying chamber, both doors 12 are closed to seal the two openings; specifically, when each door 12 is closed, the two door panels 121 are rotated to close, and then the two door panels 121 are limited by the adjustable locking and sealing member 8 and at the same time embedded into the two guiding chutes 6 for sealing, so as to prevent the heat in the drying chamber from escaping from both ends of the two guiding chutes 6 and improve the heat preservation effect during the drying process of the drying chamber.

[0038] Based on the above scheme:

[0039] The adjustable locking seal 8 includes a first seal block 81 and a second seal block 82. The first seal block 81 is slidably arranged in one of the door panels 121 in the vertical direction, and its bottom end is embedded in a guiding chute 6. Its top end passes through the outer side surface of the corresponding door panel 121 and is rotatably connected with a locking block 83. A first guiding groove 84 for the top end of the first seal block 81 to slide in the vertical direction is formed on this door panel 121. The second seal block 82 is slidably arranged in the other door panel 121 in the vertical direction, and its bottom end is embedded in another guiding chute 6. Its top end passes through to the outer side surface of the corresponding door panel 121 to form a locking portion that cooperates with the locking block 83. A second guiding groove 85 for the top end of the second seal block 82 to slide in the vertical direction is formed on this door panel 121.

[0040] After the two door panels 121 are rotated to be closed, hold the locking block 83 and the locking portion respectively to move the first seal block 81 and the second seal block 82 downward. The bottom ends of the first seal block 81 and the second seal block 82 slide into the two guiding chutes 6 in one-to-one correspondence to seal the heat dissipation channels formed by the guiding chutes 6 at the bottom of the door 12. Then rotate the locking block 83 to cooperate with the locking portion to limit the two door panels 121 (such as Figure 3 ). Among them, the first guiding groove 84 guides and limits the sliding of the first seal block 81, and the second guiding groove 85 guides and limits the sliding of the second seal block 82. Sliding channels for the corresponding first seal block 81 and second seal block 82 to slide are formed in both door panels 121.

[0041] When the door 12 needs to be opened, first rotate the locking block 83 to disengage from the locking portion to release the limit on the two door panels 121. Then hold the locking block 83 and the locking portion respectively to move the first seal block 81 and the second seal block 82 upward. The bottom ends of the first seal block 81 and the second seal block 82 are removed from the two guiding chutes 6 in one-to-one correspondence (such as Figure 4 ), and at this time, the two door panels 121 can be rotated to be opened; at the same time, the first seal block 81 and the second seal block 82 are removed from the corresponding guiding chutes 6, and will not hinder the process of the conveying rack 7 moving into or out of the drying cavity.

[0042] Among them, the bottom ends of the first seal block 81 and the second seal block 82 can both be processed from materials such as rubber, and have a certain elastic deformation, which is convenient for effectively cooperating with the guiding chute 6 for a long time.

[0043] Among the above, the locking block 83 has an embedding portion 86, and the top side of the locking portion has a clamping notch 87. The embedding portion 86 is rotated into the clamping notch 87 for cooperation. After the bottom ends of the first sealing block 81 and the second sealing block 82 slide into the two guiding chutes 6 in a one-to-one correspondence, the locking block 83 is rotated to rotate the embedding portion 86 into the clamping notch 87 to complete the limitation of the two door panels 121; the locking block 83 is rotated in the reverse direction to move the embedding portion 86 out of the clamping notch 87 to release the limitation of the two door panels 121.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
