Description

Technical Field

[0001] This utility model relates to the field of dental needle box processing technology, specifically a cutting mechanism for processing dental needle boxes. Background Technology

[0002] A dental needle case is a specialized medical toolbox used to store and sterilize various injection needles used in dental surgery. It is typically made of durable materials and features internal dividers to ensure each needle is stored individually, preventing contamination and cross-infection. The case also includes sterilization functions, such as ultraviolet lamps or high-temperature steam sterilization, ensuring the needles are sterile before each use, thus improving the safety and hygiene standards of dental procedures. During the manufacturing process, the dental needle case often requires cutting to precisely shape its form and ensure its dimensions and structure meet processing requirements.

[0003] Traditional cutting equipment for cutting needle boxes typically involves the operator holding the needle box and moving it between the needle box and the cutting disc to perform the cutting process. However, hand-held operation, with the hand close to the cutting disc, is unsafe. Furthermore, hand-held cutting is not stable enough, resulting in insufficient flatness of the cut edge, affecting the cutting quality and easily causing defective products. Utility Model Content

[0004] The purpose of this invention is to provide a cutting mechanism for processing dental needle boxes, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A cutting mechanism for processing dental needle boxes includes a processing table, a pair of placement seats symmetrically fixed above the processing table, an arched frame fixed above the processing table, two vertically extending guide rods slidably inserted through the arched frame, and a pressing seat fixed at the lower end of each guide rod, with the pressing seat corresponding to the placement seat. A drive mechanism for synchronously raising and lowering the two guide rods is provided above the arched frame, and a sliding groove extending through the arched frame between the two pressing seats is provided. A sliding carriage that can move back and forth is slidably installed in the sliding groove, and a cutting device for cutting the needle box is provided below the sliding carriage.

[0007] Therefore, the drive mechanism operates to press down the guide rod and the lower pressure seat. The lower pressure seat and the arched frame work together to press the needle box firmly, thus fixing the needle box. The cooperation of the slide and the groove allows the cutting device to feed forward and backward and retract, facilitating cutting and replacing traditional hand-held operation. It is safer. There is a pair of arched frames and lower pressure seats, located on both sides of the cutting device, ensuring that both parts are sufficiently stable after cutting. Combined with the slide sliding along the groove, it guides and limits the cutting device's feed. The pressing effect of the lower pressure seat and the arched frame on the needle box ensures that the entire cutting process is sufficiently stable, thereby ensuring a smooth cut edge, improving cutting quality, and reducing the probability of defective products.

[0008] Furthermore, the slide has a T-shaped cross-section, the carriage has a T-shaped cross-section that matches the slide, and a handle is installed at the front end of the carriage.

[0009] Furthermore, the cutting device includes a connecting rod, a U-shaped seat, a shaft, a cutting disc, and a drive module. The U-shaped seat is fixed to the lower surface of the carriage by the connecting rod. The shaft is rotatably mounted on the U-shaped seat. The cutting disc is fixedly mounted on the shaft. The drive module is mounted on one side of the U-shaped seat and is used to drive the shaft to rotate.

[0010] Furthermore, the drive module uses a drive motor, which is fixed on one side of the U-shaped base, and the output shaft of the drive motor is fixedly connected to one end of the shaft.

[0011] Furthermore, the drive mechanism includes a mounting bracket, a cylinder, and a connecting plate. The inverted L-shaped mounting bracket is fixed to the top of the arched frame, the cylinder is vertically fixed to the top of the mounting bracket, and a connecting plate is fixed to the cylinder extension rod. The connecting plate is fixed to the top of both guide rods.

[0012] Furthermore, the processing table has a rear-extending relief groove located between the two placement seats, and the cutting disc is partially matched and inserted into the relief groove, with the cutting disc penetrating the surface of the processing table both above and below.

[0013] Furthermore, dust hoods with downward openings are installed on both sides of the U-shaped base near the cutting disc. Both dust hoods are connected to a dust suction pipe, and the ends of both dust suction pipes are connected to the suction port of an industrial vacuum cleaner.

[0014] Furthermore, rubber pads are fixed on the pressing surfaces of both the arched frame and the lower pressure seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model utilizes a drive mechanism to drive the guide rod and the lower pressure seat to press down. The lower pressure seat and the arched frame work together to press the needle box tightly, thus fixing the needle box. The cooperation between the slide and the slide groove enables the cutting device to feed forward and backward and retract, making it convenient for cutting. It replaces traditional hand-held operation and is highly safe.

[0017] 2. In this utility model, an arched frame and a lower pressure seat are provided in pairs and distributed on both sides of the cutting device to ensure that the two parts after cutting are sufficiently stable. Combined with the sliding frame sliding along the slide groove, it plays a guiding and limiting role when the cutting device is fed. With the pressing effect of the lower pressure seat and the arched frame on the needle box, the entire cutting process can be ensured to be sufficiently stable, thereby ensuring a flat cutting edge, improving cutting quality, and reducing the probability of defective products.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4 This utility model provides a cutting mechanism for processing dental needle boxes, including a processing table 1, a pair of placement seats 2 symmetrically fixed above the processing table 1, an arched frame 3 fixed above the processing table 1, two vertically extending guide rods 4 slidably inserted through the arched frame 3, and a pressing seat 5 fixed at the lower end of each guide rod 4. The pressing seat 5 corresponds one-to-one with the placement seat 2. A driving mechanism 6 is provided above the arched frame 3 for synchronously adjusting the lifting and lowering of the two guide rods 4. A sliding groove 31 extending through the arched frame 3 between the two pressing seats 5 is provided. A sliding carriage 32 that can move back and forth is slidably installed in the sliding groove 31. A cutting device 7 for cutting the needle box is provided below the sliding carriage 32.

[0027] When cutting and processing the dental needle box, the needle box is first placed on the two arched frames 3. Then, the drive mechanism 6 pushes the two guide rods 4 to move down, which drives the lower pressure seat 5 to press the needle box on the arched frame 3, thus achieving the pressing and fixing of the needle box. During cutting, the slide 32 is pulled to slide forward along the slide groove 31, which drives the cutting device 7 to feed forward, thus achieving the cutting of the needle box.

[0028] The drive mechanism 6 drives the guide rod 4 and the lower pressure seat 5 to press down. The lower pressure seat 5 and the arched frame 3 work together to press the needle box tightly, thus fixing the needle box. The cooperation between the slide 32 and the slide groove 31 enables the cutting device 7 to feed forward and backward and retract, making it convenient for cutting and replacing traditional hand-held operation with high safety.

[0029] Furthermore, a pair of arched frames 3 and lower pressure seats 5 are provided and distributed on both sides of the cutting device 7 to ensure that both parts are sufficiently stable after cutting. Combined with the sliding carriage 32 sliding along the slide groove 31, it plays a guiding and limiting role when the cutting device 7 is fed. With the pressing effect of the lower pressure seat 5 and arched frames 3 on the needle box, the entire cutting process can be ensured to be sufficiently stable, thereby ensuring a flat cutting edge, improving cutting quality, and reducing the probability of defective products.

[0030] Specifically, the slide 31 has a T-shaped cross section, and the slide 32 has a T-shaped cross section that matches the slide 31. Setting the slide 31 and the slide 32 to be T-shaped with mutually matching cross sections serves as a limiting and guiding effect, which can prevent the cutting device 7 from having any vertical movement, thereby preventing the device from jumping up and down during cutting. A handle 321 is installed at the front end of the slide 32, which allows for easy force to be applied to push and pull the slide 32 to drive the cutting device 7 to feed and retract.

[0031] Specifically, the cutting device 7 includes a connecting rod 71, a U-shaped seat 72, a shaft 73, a cutting disc 74, and a drive module 75. The U-shaped seat 72 is fixed to the lower surface of the carriage 32 by the connecting rod 71. The shaft 73 is rotatably mounted on the U-shaped seat 72. The cutting disc 74 is fixedly mounted on the shaft 73. The drive module 75 is mounted on one side of the U-shaped seat 72 and is used to drive the shaft 73 to rotate.

[0032] The drive module 75 uses a drive motor, which is fixed on one side of the U-shaped seat 72. The output shaft of the drive motor is fixedly connected to one end of the shaft 73. When the drive motor works, its output shaft drives the shaft 73 to rotate, which in turn drives the cutting disc 74 to rotate. When the cutting disc 74 contacts the needle box, the cutting effect is achieved.

[0033] Specifically, the drive mechanism 6 includes a mounting bracket 61, a cylinder 62, and a connecting plate 63. The inverted L-shaped mounting bracket 61 is fixed to the top of the arched frame 3. The cylinder 62 is vertically fixed to the top of the mounting bracket 61. The connecting plate 63 is fixed on the telescopic rod of the cylinder 62. The connecting plate 63 is fixed to the top of both guide rods 4. Through the telescopic operation of the cylinder 62, its telescopic rod, under the connection of the connecting plate 63, drives the guide rods 4 and the lower pressure seat 5 to rise and fall synchronously, providing effective drive for pressing and unpressing actions.

[0034] Specifically, the processing table 1 has a rear-extending clearance groove 11 located between the two placement seats 2. The cutting disc 74 is partially matched and inserted into the clearance groove 11. The clearance groove 11 on the processing table 1 allows the cutting disc 74 to enter, thereby making room for the cutting disc 74 and avoiding obstruction or interference from the moving cutting action of the cutting disc 74 by the processing table 1. The cutting disc 74 penetrates the surface of the processing table 1 from top to bottom. By placing a collection container under the clearance groove 11, the cutting debris falling from the clearance groove 11 can be collected.

[0035] Specifically, dust hoods 721 with downward openings are installed on both sides of the U-shaped base 72 and near the cutting disc 74. Dust suction pipes 722 are connected to both dust hoods 721. The ends of both dust suction pipes 722 are connected to the suction port of an industrial vacuum cleaner (not shown in the figure). The negative pressure generated by the operation of the industrial vacuum cleaner can be used to sequentially draw in and collect the smoke, dust and fine dirt generated during cutting through the dust hoods 721 and the dust suction pipes 722, so as to ensure the processing site environment and air quality.

[0036] Specifically, rubber pads (not shown in the figure) are fixed on the pressing surfaces of the arched frame 3 and the lower pressing seat 5. The rubber pads are soft and serve two purposes: firstly, they provide an anti-slip effect when the needle box is pressed, ensuring a more stable pressing and fixing; secondly, they provide a buffer protection for the needle box, preventing excessive pressing and damage to the outer surface of the needle box.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
