Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, and in particular to a dental prosthesis cutting device. Background Technology

[0002] Dentures, also known as "false teeth," are a general term in medicine for restorations made after partial or complete loss of the upper and lower jaw teeth. Dentures are divided into two types: removable and fixed. Fixed dentures cannot be removed by the patient, while removable dentures can be easily removed by the patient. During the processing of dentures, a cutting device is needed to cut them.

[0003] To this end, patent CN221967441U discloses a denture cutting device, including a worktable and a cutting part. A clamping part is fixedly mounted on the worktable, comprising: a clamping base, which is a hollow cylindrical structure with a screw through hole at the bottom and multiple clamping tooth grooves; a screw threadedly connected to the screw through hole; a connecting block, which is cylindrical and has a sliding groove; and clamping teeth, whose shafts rotate within the rotating grooves, with one end sliding within the sliding grooves. This invention utilizes the synergistic effect of the screw, connecting block, and clamping teeth to achieve simple and rapid fixation of the denture; the clamping center position is fixed, and the clamping teeth push the denture into position, ensuring accurate denture positioning.

[0004] Existing denture cutting devices generate shavings during use, which are difficult to remove and can pollute the environment, affecting the cutting efficiency of the device. Utility Model Content

[0005] The purpose of this invention is to provide a denture cutting device to solve the problem of poor dust removal effect in existing denture cutting devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a denture cutting device, including a fixed frame, a support frame installed at the top of the fixed frame, and a drive cylinder installed on the support frame. A lifting frame is installed at the output end of the drive cylinder, a drive motor is installed at the bottom end of the lifting frame, and a cutting blade is installed at the output end of the drive motor. A protective structure is provided on the lifting frame. A base is installed at the bottom end of the fixed frame, and a worktable is installed on the base. Chucks are evenly installed on the worktable. An auxiliary mechanism is provided inside the base. A dust removal mechanism is provided at the bottom of one end of the base. The dust removal mechanism includes a dust removal box installed at the bottom of one end of the base, a suction pipe and an air outlet installed at the top and bottom of the dust removal box respectively, a fan installed at the bottom of the dust removal box, a filter screen installed inside the dust removal box, sliders installed on both sides of the filter screen, and sliding grooves opened on both sides of the dust removal box.

[0007] Preferably, the slider is inserted into the groove and forms a sliding connection therewith.

[0008] The above structure makes it easy to pull out the filter for cleaning and replacement.

[0009] Preferably, the protective structure includes a first protective cover, a second protective cover, a limiting groove, and a telescopic spring. The first protective cover is installed at one end of the lifting frame. A limiting groove is formed at the bottom of the first protective cover, and a telescopic spring is evenly installed inside the limiting groove. The second protective cover is installed at the bottom of the telescopic spring.

[0010] Preferably, the first protective cover and the second protective cover are arc-shaped.

[0011] The above structure can shield the cutting area during cutting, preventing waste chips from flying everywhere.

[0012] Preferably, the top of the second protective cover is disposed in the limiting groove, and the second protective cover and the telescopic spring form a telescopic structure.

[0013] The above structure allows the second protective cover to come into contact with the workbench.

[0014] Preferably, the auxiliary mechanism includes a fixed motor, a belt assembly, a brush, a connecting shaft, a rotating shaft, and a turntable. The fixed motor is installed inside the base, and a rotating shaft is installed at the output end of the fixed motor. A turntable is installed at the top of the rotating shaft, and the top of the turntable is connected to the bottom of the workbench. The connecting shaft is installed at the top of the dust collection box, and the connecting shaft and the rotating shaft are connected by a belt assembly. A brush is installed at the bottom of the connecting shaft.

[0015] With the above structure, the rotating worktable drives the brush to rotate, cleaning the filter screen.

[0016] Preferably, the width of the brush is smaller than the width of the dust collection box.

[0017] The above structure allows the brush to rotate.

[0018] The advantages of the denture cutting device provided by this utility model are as follows:

[0019] The dust removal mechanism can suck the waste generated during the cutting of dentures into the dust collection box to achieve the purpose of dust removal. The auxiliary mechanism drives the brush to rotate when the worktable rotates to clean the filter screen. The protective structure can shield the cutting area during cutting to prevent waste from flying.

[0020] By setting up a dust removal mechanism and starting the fan, the waste generated during the cutting of dentures can be sucked into the dust removal box through the suction pipe to achieve the purpose of dust removal. The filter screen can block the waste. Pull out the filter screen and remove it to achieve the purpose of cleaning and replacement.

[0021] With the help of the auxiliary mechanism, the fixed motor starts and the turntable drives the worktable to rotate, so that feeding, unloading and cutting can be carried out simultaneously. At the same time, the belt assembly drives the connecting shaft to rotate and the brush to rotate, which can clean the filter screen and prevent it from clogging.

[0022] With the protective structure in place, the lifting frame moves the first protective cover down, and the second protective cover comes into contact with the workbench, blocking the cutting area and achieving the purpose of protection, thus preventing the flying of waste chips that could injure workers.
