Description
Technical Field
[0001] This utility model relates to the field of fabric cutting technology, and in particular to a cutting bed fan installation structure. Background Technology
[0002] In production and daily life, it is necessary to cut fluffy fabrics, which is done through a cutting table. To improve cutting accuracy, a vacuum structure is installed to extract air from the fabric on the conveyor belt, making the fabric more compact and improving cutting precision. During vacuuming, the extracted air is discharged through an exhaust pipe. To install the blower of the vacuum system, a blower mounting structure needs to be installed on the cutting table. The existing blower mounting structure can only accommodate the installation of a single-power turbine blower (the mounting hole positions are different for blowers of different power). Summary of the Invention
[0003] This utility model provides a cutting bed fan installation structure that can adapt to the installation of fans in different installation positions, solving the problem that the existing cutting bed fan installation structure can only be used for the installation of one type of fan.
[0004] The above technical problems are solved by the following technical solution: a cutting bed fan mounting structure, the fan including a fan body and a fan motor that drives the fan body to rotate, the fan body and the fan motor are connected together by a drive belt for transmission, characterized in that it includes a connecting base frame, a motor suspension plate with a rotating shaft at one end and a fan body fixing frame connected to the connecting base frame, the fan body is connected to the fan body fixing frame, the motor suspension plate is provided with a plurality of suspension plate mounting hole groups corresponding to fan part mounting hole groups of fan motors of different power, the fan motor is fixed to the motor suspension plate by motor mounting bolts passing through the fan part mounting hole groups and the corresponding set of suspension plate mounting hole groups, and then by motor mounting nuts, the motor suspension plate and the fan body fixing frame are provided with a belt tensioning mechanism for changing the distance between the motor suspension plate and the fan body fixing frame to tension the drive belt.
[0005] Preferably, the belt tensioning mechanism includes a connecting notch on the edge of the motor suspension plate away from the rotating shaft and a support rod with one end hinged to the fan body fixing frame. The other end of the support rod passes through the connecting notch, and a limiting nut that holds the motor suspension plate in its current position is threaded onto the support rod.
[0006] Preferably, there is only one limiting nut, and the weight of the fan motor is such that the drive motor suspension plate rests against the motor suspension plate on the motor suspension.
[0007] Preferably, the limiting nut is located on the side of the motor suspension plate facing the fan body fixing frame.
[0008] Preferably, the connecting base frame is provided with a load-bearing beam, which includes a vertical beam plate and a horizontal beam plate connected to the upper end of the vertical beam plate. The fan body is fixedly mounted with a connecting fork formed by connecting one end of an upper fork and a lower fork. The horizontal beam plate passes through the connecting fork. The free end of the lower fork is provided with a downwardly bent lower abutment rod, which abuts against the vertical beam plate. The weight of the fan body drives the lower abutment rod to abut against the vertical beam plate.
[0009] Preferably, the inlet end of the blower body is provided with an air inlet pipe, and the inlet end of the air inlet pipe is connected to a filter cover. One end of the filter cover is provided with an end cap, and the other end is connected to the inlet end of the air inlet pipe. In use, the vacuumed airflow passes through the filter cover and reaches the air inlet pipe. The load is filtered and blocked by the filter cover, thereby preventing it from entering the exhaust fan and damaging the equipment.
[0010] Preferably, the system also includes an air inlet cavity, which has a tubular section fitted onto the filter cover. One end of the tubular section forms a filter cover removal hole. An end cap is detachably connected to the filter cover removal hole and closes it. The end cap has a positioning structure that extends into the filter cover to prevent radial movement of the filter cover relative to the end cap. When the filter cover needs cleaning, the end cap is detached from the filter cover removal hole, and then the filter cover is removed. This facilitates filter cover maintenance and allows airflow to converge into the air inlet duct.
[0011] Preferably, the positioning structure includes a plurality of ribs extending radially along the circumference of the end cap, the outer end faces of the ribs being located on the same circle, and the radius of the circle containing the outer end faces of the ribs being less than 1 mm smaller than the inner radius of the filter cover. This design is simple and increases the strength of the end cap.
[0012] Preferably, the inlet end of the air inlet duct is connected to two positioning strips, which are connected together in a cross shape and abut against the inner circumferential surface of the filter cover. This increases the structural strength of the filter cover and allows for zoned air intake, thereby increasing the anti-clogging effect.
[0013] Preferably, the end face of the positioning strip away from the inlet end of the air inlet pipe has chamfered ends. This makes it easier to fit the filter cover onto the positioning strip.
[0014] This utility model has the following advantages: it has two mounting positions, which are suitable for the installation of fans with different power. Attached Figure Description
