Description

Technical Field

[0001] The utility model relates to the technical field of gutta-percha point production, in particular to gutta-percha point production equipment. Background Art

[0002] The raw material of medical device gutta-percha points is generally rubber, which has good plasticity. It can become soft when heated to 40 degrees Celsius and harden after cooling. It fills tightly and has good tissue affinity. It can be easily removed from the root canal. It is non-conductive and non-electrical. The production process of gutta-percha points is generally to cut the rubber material into particles first, and then process it through heating, softening and molding processes. In order to reduce the workload of personnel, there is currently automatic cutting gutta-percha point production equipment.

[0003] For example, an existing Chinese patent (publication number: CN204909684U) discloses a tooth rubber tip cutting machine. When the end of the strip rubber moves to the bottom of the cutting knife, the cylinder drives the movable plate to move downward, and the pressing plate presses the end of the strip rubber. At the same time, the cylinder drives the cutting knife to move downward to cut the end of the strip rubber. After the cutting knife completes one cut, the cutting knife moves upward under the drive of the cylinder, and the stepping motor drives the sliding plate to move toward the cutting mechanism. Repeating the above operation can complete the next cut.

[0004] However, the above-designed gutta-percha cutting machine still has some disadvantages in practical application: although the above-designed gutta-percha cutting machine can cut automatically, the cylinder is extended to drive the knife body to press down to cut the rubber during use. This method causes great wear and tear on the knife body and is prone to blade curling problems, which not only increases unnecessary maintenance costs but also reduces production efficiency. For this reason, we have designed a gutta-percha production equipment to solve the above problems. Utility Model Content

[0005] The utility model provides a device for producing gutta-percha tips. By turning on a first electric push rod, a U-shaped part can be made to slide on the top of a base and move the rubber strip to below a blade. Then, by cooperating with turning on a second electric push rod, the blade can be made to move downward and cut the rubber strip. During this process, by turning on a motor, a rotating shaft can drive a turntable to rotate, so that a transmission shaft drives a rotating part, a sliding part and a blade to slide back and forth in a sliding opening along a direction set by a guide rod, thereby achieving an effect of sawing the rubber strip, thereby helping to delay the problem of curling of the blade and solving the problems mentioned in the above-mentioned background technology.
