Description
Technical Field
The utility model relates to the technical field of guide conduit preparation, in particular to a bottom clamping and tensioning device of a conduit film laminating machine.
Background
Catheter coaters are a common apparatus used to manufacture multi-layer stiffened guide catheters. The guide catheter typically comprises a low friction, ultra-thin inner polymer tube, a braided wire sheath, and multiple outer polymer tubes of varying hardness, color, and other characteristics. After the tubes are pre-assembled together with the inner tube supporting guide wire and the outer layer heat shrinkable tube, the tubes are placed into a clamping system of a film laminating machine, then the pre-assembled tubes are heated along the way by a heating nozzle, so that the heat shrinkable tube shrinks, the outer tube melts and fixes the braided layer and the inner tube into a whole. In the process, one end of the catheter needs to be fixed in the upper catheter clamp, in order to ensure that the catheter is straightened in the vertical direction, the bottom end of the catheter also needs to be fixed and a certain tensioning force is applied, the catheter cannot be laterally deviated by fixing the catheter through a guide hole, and meanwhile, a proper weight is added at the bottom end of the catheter to ensure tensioning, so that the efficiency is low and the reliability is poor.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims to provide a bottom clamping and tensioning device of a catheter covering machine, which has good stability, wide application range and strong reliability, aiming at the defects of the prior art.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a bottom clamping and tensioning device of a pipe film laminating machine comprises a fixed bottom plate, a tensioning cylinder vertically arranged on the fixed bottom plate, a bidirectional sliding table cylinder arranged at the top end of the telescopic end of the tensioning cylinder, and a multi-claw clamping group arranged on the bidirectional sliding table cylinder; the multi-claw forceps holder group comprises clamping jaws which are respectively arranged on the two sliding tables of the bidirectional sliding table cylinder.
According to the technical scheme, the device is fixed on the catheter laminating machine through the fixing bottom plate, the two-way sliding table cylinder drives the two clamping jaws to move relatively, the bottom end of the supporting mandrel of the guide catheter is clamped in the multi-jaw clamp group, the tensioning cylinder drives the bottom end of the supporting mandrel to move downwards to adjust the tensioning force of the guide catheter, and the operation is simple and the control is convenient.
Preferably, the clamping jaw is in including the mounting panel and the vertical setting of level setting the terminal splint of mounting panel the splint inboard is equipped with the clamping jaw tooth, and two the clamping jaw tooth crossing arrangement of clamping jaw. The clamping and grabbing of the guide catheter are facilitated, and the stress of the guide catheter is uniform.
Preferably, the pawl tooth is provided in a "dog" shape. The guide tubes with different sizes are more conveniently clamped, the guide tubes are horizontally limited, and the stability of the guide tubes is improved.
Preferably, the tensioning cylinder is a double guide rod cylinder. Two-way slip table cylinder and clamping jaw are more steady when reciprocating.
The utility model has the beneficial effects that:
the multi-jaw clamping set ensures reliable clamping of the guide pipe, uses all the guide pipe sizes in the design range, does not need to replace a clamp, and has wide application range and convenient use; the tensioning cylinder can provide constant tension and is reliable and easy to adjust.

Detailed Description
The utility model is further described below with reference to the figures and examples.
As shown in fig. 1 to 5, a bottom clamping and tensioning device for a conduit film covering machine comprises a fixed base plate 1 arranged on the conduit film covering machine, a tensioning cylinder 2 vertically arranged on the fixed base plate 1, a bidirectional sliding table cylinder 3 arranged at the top end of the telescopic end of the tensioning cylinder 2, and a multi-claw clamping set arranged on the bidirectional sliding table cylinder 3. The tensioning cylinder 2 is here a double guide rod cylinder.
The multi-claw clamping set comprises clamping jaws 4 which are respectively and relatively fixedly arranged on two sliding tables 8 of the bidirectional sliding table cylinder 3. The clamping jaw 4 comprises a horizontally arranged mounting plate 5 and a clamping plate 6 vertically arranged at the tail end of the mounting plate 5, wherein the inner side of the clamping plate 6 is provided with a clamp dog tooth 7 in a V shape, and the clamp dog teeth 7 of the two clamping jaws 4 are arranged in a crossed manner.
The bidirectional sliding table cylinder 3 and the tensioning cylinder 2 are electrically connected with a controller on the catheter film laminating machine, the working states of the bidirectional sliding table cylinder 3 and the tensioning cylinder 2 are adjusted by controlling the pressure of compressed air, and the opening and closing of the two clamping jaws 4 are accurately adjusted. The controller and the catheter laminator are both prior art.
When a plurality of clamping and tensioning devices are arranged on the conduit film laminating machine, all the two-way sliding table air cylinders 3 and the tensioning air cylinders 2 are connected with the same air source, so that the tension provided by each tensioning air cylinder 2 is consistent, and the tension born by each conduit is consistent.
The working principle of the utility model is as follows: the bidirectional sliding table cylinder 3 operates under the control of the controller, the two clamping jaws 4 move relatively to clamp the bottom of the guide pipe between the two clamping jaws 4, and the tensioning cylinder 2 starts the telescopic rod to retract to drive the guide pipe to be pulled down, so that the guide pipe is tensioned. The two-way sliding table cylinder 3 drives the two clamping jaws 4 to move oppositely, and the guide pipe is loosened.
The apparatus elements referred to in the above embodiments are conventional apparatus elements unless otherwise specified, and the structural arrangements, operations, or controls referred to in the above embodiments are conventional in the art unless otherwise specified.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent substitutions made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
