Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of paint processing, and particularly relates to a heat dissipation mechanism of a sand mill. BACKGROUND

[0002] Paint is a chemical mixture coating that can firmly cover the surface of an object and is used for protection, decoration, marking and other special purposes. The coating is generally composed of four parts, namely, film-forming material, filler (pigment filler), solvent and additive. In the production and processing of paint, sanding treatment is required for paint raw materials.

[0003] The existing Chinese patent with the publication number CN220697026U discloses a paint sand mill, which comprises a sanding cylinder, a support seat is clamped at the bottom of the sanding cylinder, a discharge pipe penetrates through the bottom of the support seat, the top of the discharge pipe is fixedly connected with the sanding cylinder, a sealing cover is sleeved at the top of the sanding cylinder, a motor is fixedly connected to the top of the sealing cover, and a cooling mechanism is arranged outside the sanding cylinder.

[0004] Although the sand mill has the heat dissipation performance, the heat dissipation efficiency is not high, and the performance is poor. Therefore, the sand mill needs to be improved. CONTENT OF THE UTILITY MODEL

[0005] The application aims to provide a heat dissipation mechanism of a sand mill to improve the heat dissipation efficiency of the sand mill.

[0006] The application provides a heat dissipation mechanism of a sand mill, which comprises:

[0007] The sand mill body comprises a cylinder, a grinding block and a driving motor.

[0008] The fan is installed on the cylinder.

[0009] The cooling assembly is arranged on the outer wall surface of the cylinder and is uniformly distributed around the axis of the cylinder.

[0010] The connecting pipe is installed on the outer wall surface of the cylinder.

[0011] The temperature sensor is installed on the corresponding cooling assembly.

[0012] The transmission mechanism is connected between the driving motor and the fan.

[0013] The grinding block is arranged in the cylinder and is connected with the driving motor, the connecting pipe is connected between the fan and the cooling assembly, and the cooling assembly comprises a cooling cavity and a cooling plate.

[0014] The sand mill body is driven to rotate by a driving motor to grind the grinding block. The heat generated during the grinding process is transferred to the cooling assembly installed on the cylinder body. When the fan is driven, the flowing air is transported into the connecting pipe connected with the cooling assembly, so that the air flows quickly through the cooling assembly for heat dissipation. The cooling cavity is formed by the cooling plate. The cooling cavity and the cooling plate increase the contact area with the air, thereby improving the heat dissipation efficiency. The temperature sensor is used to detect the temperature of the corresponding cooling assembly position, thereby improving the monitoring of the cooling effect of the corresponding cooling assembly. The driving motor is connected with the fan through the transmission mechanism, thereby reducing the installation of other driving devices.

[0015] Further, the connecting pipe comprises:

[0016] The connecting head is connected to the connecting pipe at one end and is provided with a connecting port inserted into the cooling cavity at the other end.

[0017] The opening area is arranged between the connecting pipe and the cooling assembly.

[0018] The adjusting mechanism is arranged between the connecting head and the connecting pipe.

[0019] The connecting head is connected to the connecting pipe by threads or fasteners. The connecting head has multiple connecting ports, which are inserted into the corresponding cooling cavities. When the air flow is transported into the connecting head through the connecting pipe, the air flow is blown out through the connecting ports on the connecting head and transported into the cooling assembly. The opening area is arranged to facilitate the simultaneous and rapid entry of air outside the cooling assembly into the cooling assembly at the connecting port and the cooling cavity, thereby increasing the amount of air flowing through the cooling assembly and further improving the cooling efficiency of the cooling assembly. The adjusting mechanism is adjusted so that the air flow through each connecting head of the connecting pipe is the same, thereby further improving the uniformity of the heat dissipation performance of the cylinder.

[0020] Further, the adjusting mechanism comprises:

[0021] The adjusting block is movably mounted on the connecting pipe.

[0022] The lead screw is movably mounted on the connecting pipe.

[0023] The lead screw is provided with two thread portions with opposite thread directions. The adjusting block is connected with the thread portions. The lead screw is provided with a handle portion.

[0024] The adjusting block is moved to adjust the adjusting mechanism. The handle portion is rotated to rotate the lead screw. The adjusting block is mounted on the thread portion of the lead screw to adjust the opening and closing size of the adjusting block.

[0025] Further, the fan comprises:

[0026] The housing is mounted on the sand mill body.

[0027] The fan blade is movably installed in the cover.

[0028] The cover is installed on the sand mill body by fasteners such as bolts and nuts. The cover adopts the structure of a centrifugal fan, facilitating the installation between the fan blade and the transmission mechanism and the flow of air. The fan blade of the cover adopts the fan blade of the centrifugal fan. The air outlet of the cover is connected with the connecting pipe.

[0029] Further, the transmission mechanism comprises:

[0030] The transmission shaft is installed on the sand mill body.

[0031] The transmission shaft is connected with the output shaft of the driving motor through a gear transmission, and the transmission shaft is connected with the mounting shaft of the fan blade through a gear transmission.

[0032] The transmission shaft is installed on the sand mill body through a bearing. The power on the output shaft of the driving motor is transmitted to the fan blade of the fan through a rotating shaft and a gear, so as to realize the rotation of the fan blade.

[0033] Further, the transmission shaft comprises:

[0034] The telescopic rod is provided with a piston.

[0035] The piston is arranged in the transmission shaft.

[0036] The telescopic rod is controlled to be extended or retracted by moving the piston, so that the transmission shaft can be extended or retracted. In the normal state, the transmission shaft is in the extended state, so that the power of the driving motor is transmitted to the fan. When the telescopic rod controlled by the transmission shaft is in the retracted state, the power on the driving motor cannot be transmitted to the fan, which is suitable for low-speed grinding of the grinding block and does not need to be cooled.

[0037] The beneficial effects of the present application are:

[0038] 1. When the fan is driven, the flowing air is transported into the connecting pipe, and the connecting pipe is connected with the cooling assembly, so that the air is quickly flowed through the cooling assembly for heat dissipation.

[0039] 2. The cooling cavity is formed by the cooling plate, the contact area with air is increased by the cooling cavity and the cooling plate, and the heat dissipation efficiency is improved.

[0040] 3. The driving motor is connected with the fan through the transmission mechanism, and the installation of other driving devices is reduced. BRIEF DESCRIPTION OF DRAWINGS
