DETAILED DESCRIPTION

[0019] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0021] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0025] Example

[0026] like Figure 1-5 As shown, the polytetrafluoroethylene catheter extruder proposed in the utility model includes a catheter extruder body 1 and a silo 2 installed on the top of the catheter extruder body 1, and also includes: an abrasive mechanism fixedly installed on the top of the silo 2 for dispersing the agglomerated materials after repeatedly stirring the materials poured into the silo 2; a vibration mechanism, which is arranged at the bottom of the abrasive mechanism for transporting the dispersed small particle materials into the catheter extruder body 1.

[0027] Further, the abrasive mechanism includes a vibrating material plate 3 fixedly installed in the silo 2, and a guide groove 33 is provided inside the vibrating material plate 3 for guiding all the materials poured into the vibrating material plate 3 to the vibrating material leakage plate 4. The function of the guide groove 33 is that the materials poured into the vibrating material plate 3 will all gather on the vibrating material leakage plate 4 through the action of vibration and gravity. A support block 42 is provided inside the vibrating material plate 3, and a top cover 5 is fixedly connected to the upper surface of the support block 42. The top of the top cover 5 is set to be a cone for guiding the materials poured into the vibrating material plate 3 to the vibrating material leakage plate 4. The function of the cone is to prevent the materials from staying on the vibrating material leakage plate 4 and being unable to slide down. A motor 51 is fixedly connected inside the top cover 5, and the output shaft of the motor 51 is movably penetrated through the top cover 5 and then fixedly connected to a rotating block 52. A pair of rotating rods 53 are fixedly connected to the outer wall of the rotating block 52, and a plurality of linearly arranged abrasive scattering rods 54 are fixedly connected to the lower surface of the rotating rod 53.

[0028] Among them, the vibration mechanism includes a vibration expansion slot 31 opened in the vibration material disc 3. The function of the vibration expansion slot 31 is to enable the vibration material leakage disc 4 to move up and down when vibrating. At the same time, the vibration expansion slot 31 can prevent the vibration material leakage disc 4 from moving up and down too much or too little. The vibration expansion slot 31 is internally fixedly connected with a plurality of buffer springs 32 distributed in a circular array. The function of the buffer spring 32 is to enable the vibration material leakage disc 4 to return to its original position after the vibration expansion slot 31 vibrates. The vibration expansion slot 31 is internally movably connected with an annular clamping block 41. The lower surface of the annular clamping block 41 is fixedly connected to the buffer spring 32. The internal fixed sleeve of the annular clamping block 41 is provided with a vibration material leakage disc 4 fixedly connected to the support block 42. The vibration material leakage disc 4 is provided with a plurality of small holes for the scattered materials to pass through. The size of the small hole is such that a grain of polytetrafluoroethylene raw material can easily pass through. The vibration mechanism also includes a bottom cover 6 fixedly connected to the lower surface of the support block 42, and a vibration motor 61 is fixedly connected inside the bottom cover 6. The vibration motor 61 is a common industrial equipment used to transmit, screen, convey or process materials through vibration. It is usually composed of a motor and a vibration device, and the vibration device is driven by the motor to work.

[0029] Furthermore, the distance between the bottom end of the rotating block 52 and the top end of the top cover 5 is smaller than the diameter of the material particles, so as to prevent the material particles from being stuck in the distance between the rotating block 52 and the top cover 5, thereby preventing the use of the motor 51 from being affected. The top end of the rotating block 52 is configured as a hemispherical shape for guiding the material into the vibrating material drain plate 4 in the vibrating material plate 3, and the hemispherical shape prevents the material from staying and getting stuck on the rotating block 52.

[0030] In this embodiment, when a polytetrafluoroethylene catheter extruder is required, Figure 1 As shown, the material is poured into the silo 2 through the conveying mechanism and slides onto the vibrating material leaking plate 4 in the vibrating material plate 3. The vibrating motor 61 on the vibrating mechanism at the bottom of the vibrating material leaking plate 4 allows the agglomerated and dispersed materials or the non-agglomerated materials to quickly pass through the small holes on the vibrating material leaking plate 4. At this time, the agglomerated and non-dispersed materials on the vibrating material leaking plate 4 will remain on the vibrating material leaking plate 4, and then the motor 51 on the abrasive mechanism is started, and the output shaft of the motor 51 drives the rotating block 52 to rotate, and the rotating block 52 drives a pair of rotating rods 53 and a plurality of abrasive breaking rods 54 on the lower surface of the rotating rod 53 to stir and break up the agglomerated materials on the vibrating material leaking plate 4. The broken up materials pass through the small holes on the vibrating material leaking plate 4 and then enter the catheter extruder body 1 for use. The agglomerates that are not completely broken up cannot pass through the small holes on the vibrating material leaking plate 4, and then are repeatedly stirred and broken up by the abrasive mechanism, so that the agglomerated materials are completely broken up. Finally, some lumps are not completely broken up, and the lumps are taken out from the vibrating material leakage plate 4, and then manually broken up or judged whether they can be used.

[0031] The preferred embodiments of the utility model of the above utility model are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
