Description

Technical Field

[0001] This utility model belongs to the field of medical catheter core extraction technology, and specifically relates to a feeding tray for a medical catheter core extraction mechanism. Background Technology

[0002] Medical catheters are tubular instruments, generally made of soft polymer materials. During the manufacturing process, a relatively rigid mandrel is required as a guide and support to ensure that the shape, size, and performance of the catheter meet medical requirements. However, during the manufacturing process, the inner wall of the catheter and the mandrel may bond together due to heat. Therefore, when the intermediate process of the catheter is completed, the mandrel needs to be removed from the catheter for subsequent processing.

[0003] Currently, with the rapid development of intelligent manufacturing technology and the increasing demands for production efficiency and product quality in the medical industry, core extraction of medical catheters is gradually becoming automated. During core extraction, to ensure continuous production, a feeding tray is needed to orderly transport the catheters to be extracted, achieving seamless integration between different processes. However, existing feeding trays are mostly of fixed length, meaning each size of tray is designed for a specific type of medical catheter. This design not only increases the cost of purchasing trays of different sizes and occupies a significant amount of production space for storing various trays, but also leads to production interruptions due to frequent tray changes when producing different sizes of medical catheters. This reduces production efficiency, affects production flexibility and responsiveness, and makes it difficult to meet the diverse needs of modern medical catheter production. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model aims to provide a feeding tray for a medical catheter core extraction mechanism, which is adjustable in length to meet the needs of medical catheters of different specifications and sizes, thereby expanding the scope of application, reducing costs and improving production efficiency.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A feeding tray for a medical catheter core extraction mechanism includes a base, on which an active slider and at least one set of driven sliders are disposed. The base, the active slider, and the driven sliders are provided with a pair of placement slots for placing medical catheters. The active slider and the driven sliders are connected together by a scissor-type connecting rod, one end of which is connected to the base. An adjustment and fixing mechanism is provided between the base, the active slider, and the driven sliders.

[0007] Furthermore, the base includes a left foot block and a right foot block, which are connected together by at least one pair of fixed shafts; the placement slot is formed on the right foot block, and the active slider and the driven slider are slidably disposed on the fixed shafts, with one end of the scissor-type connecting rod connected to the right foot block.

[0008] Furthermore, the lower ends of the left foot block and the right foot block are respectively provided with pads.

[0009] Furthermore, a first clearance hole is provided in the placement groove on the right foot block, and a sensor is provided below the first clearance hole. All the sensors are mounted on a support base.

[0010] Furthermore, linear bearings are respectively provided between the active slider and the driven slider and the fixed shaft.

[0011] Furthermore, the adjustment and fixing mechanism includes a lead screw passing through the base, the active slider, and the driven slider, as well as at least one set of cross clamps connected to the active slider.

[0012] Furthermore, the adjustment and fixing mechanism includes a lead screw passing through the base, the active slider, and the driven slider, as well as at least one set of cross clamps connected to the driven slider.

[0013] Furthermore, an internal hexagonal hole is provided on one end face of the lead screw; or, the outer surface of one end of the lead screw is hexagonal.

[0014] Furthermore, one end of the lead screw is connected to a drive motor via a coupling.

[0015] The beneficial effects of this utility model are as follows: Through the cooperation of the active slider, the driven slider, and the scissor-type connecting rod, as well as the adjusting action of the adjusting and fixing mechanism, this utility model can achieve equidistant adjustment of the active slider and the driven slider within the base, thereby meeting the placement requirements of medical catheters of different specifications and sizes. This greatly expands the applicability of the feeding tray, eliminating the need for enterprises to purchase trays of various specifications, reducing cost investment, and effectively avoiding production interruptions caused by frequent replacement of feeding trays when producing medical catheters of different specifications. It also reduces the time spent on replacing trays, enabling smoother connections between various processes, effectively improving production efficiency, enhancing production flexibility and rapid response capabilities, and better meeting the diversified needs of modern medical catheter production.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] See Figure 1-6 As shown, a feeding tray for a medical catheter core extraction mechanism includes a base 1. The base 1 has an active slider 2 and six sets of driven sliders 3 that can slide on it. A pair of placement slots 123 for placing medical catheters are formed on the base 1, the active slider 2, and the driven sliders 3. The active slider 2 and the driven sliders 3 are connected together by a scissor-type connecting rod 4, one end of which is connected to the base 1. An adjustment and fixing mechanism 5 is provided between the base 1, the active slider 2, and the driven sliders 3. During adjustment, the adjustment and fixing mechanism 5 drives the active slider 2 to slide within the base 1. At this time, the sliding active slider 2 drives the six sets of driven sliders 3 to slide within the base 1 via the scissor-type connecting rod 4, achieving equidistant adjustment of the active slider 2 and the driven sliders 3 within the base 1. The adjustment and fixing mechanism 5 locks the adjusted positions of the active slider 2 and the driven sliders 3 to prevent movement. It should be noted that the number of sets of driven sliders 3 described above is only one implementation method and is not intended to limit the scope of this application. In actual implementation, more or fewer sets can be set as long as the usage requirements are met. Also, 10 sets of corresponding placement slots 123 are respectively opened on the base 1, the active slider 2 and the driven slider 3. That is, in this embodiment, 10 medical catheters can be loaded at a time.

[0030] Further, see Figure 2 As shown, in this embodiment, the base 1 includes a left foot block 11 and a right foot block 12. The left foot block 11 and the right foot block 12 are connected together by two pairs of fixed shafts 13. The number of pairs of fixed shafts 13 is not limited to two; other pairs can be provided as long as the usage requirements are met. In addition, in this embodiment, the placement groove 123 is formed on the right foot block 12, and the active slider 2 and the driven slider 3 are slidably disposed on the fixed shafts 13.

[0031] Further, see Figure 2-7As shown, in this embodiment, the lower ends of the left foot block 11 and the right foot block 12 are respectively provided with pads 14; and a first clearance hole 121 is respectively opened in the placement groove 123 on the right foot block 12. A sensor 15 is respectively provided below the first clearance hole 121. All the sensors 15 are mounted on a support base 16. In use, the sensors 15 monitor whether a medical catheter is placed in the placement groove 123.

[0032] Further, see Figure 5-6 As shown, in this embodiment, linear bearings 6 are respectively provided between the active slider 2 and the driven slider 3 and the fixed shaft 13. By providing the linear bearings 6, the active slider 2 and the driven slider 3 can slide smoothly and accurately on the fixed shaft 13.

[0033] Further, see Figure 2-6 As shown, in this embodiment, the adjusting and fixing mechanism 5 includes a lead screw 51 and two sets of cross clamps 52. The number of cross clamps 52 is not limited to two sets; more or fewer sets can be used, as long as the usage requirements are met. During installation, the lead screw 51 passes between the left foot block 11, the right foot block 12, the active slider 2, and the driven slider 3. The lead screw 51 is rotatably mounted within the left foot block 11 and the right foot block 12 via corresponding bearings, and one end of the lead screw 51 extends from the left foot block... The screw 51 protrudes from the inner part of the slide; the lead screw 51 is threadedly connected to the active slider 2, and the driven slider 3 has a second clearance hole for the lead screw 51 to pass through. The diameter of the second clearance hole is slightly larger than the diameter of the lead screw 51. Two sets of cross clamps 52 are fixed on the active slider 2, or two sets of cross clamps 52 are fixed on the driven slider 3. In this case, the fixed shaft 13 passes through the clamping mouth of the cross clamp 52, and in the use state, the cross clamp 52 is in a clamping state on the fixed shaft 13.

[0034] During adjustment, after releasing the cross clamp 52 from the fixed shaft 13, the active slider 2 is driven to move closer to / away from the right foot block 12 along the fixed shaft 13 by rotating the lead screw 51. This, in turn, drives the six sets of driven sliders 3 to move closer to / away from the right foot block 12 along the fixed shaft 13 via the scissor-type connecting rod 4. This achieves equidistant adjustment of the distance between the active slider 2, driven sliders 3, and right foot block 12, reducing / expanding their size. After adjustment, the cross clamp 52 is re-clamped onto the fixed shaft 13. This adjustment allows for the placement of medical catheters of different sizes. It should be noted that... Yes, in this embodiment, by setting the cross clamp 52, it can effectively prevent the lead screw 51 from rotating due to vibration or misoperation during operation, thus preventing changes in the distance between the active slider 2, the driven slider 3, and the right foot block 12, which would affect the placement or loading of medical catheters. Secondly, in this embodiment, in order to enable rotation of the lead screw 51 during adjustment, an internal hexagonal hole (not shown in the figure) is provided on the end face of the lead screw 51 that passes through the left foot block 11, or, the outer surface of one end of the lead screw 51 is hexagonal (not shown in the figure), and the lead screw 51 is manually adjusted by a wrench during adjustment; or, see Figure 8 As shown, one end of the lead screw 51 is connected to a drive motor 54 via a coupling 53. During adjustment, the drive motor 54 drives the lead screw 51 to rotate via the coupling 53, thereby achieving automatic adjustment.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
