A hollow guide rail foam strip stuffing device with double foam cans and its working method

Abstract

The invention discloses a hollow guide rail foam strip stuffing device with double foam cans and a working method, which includes a bracket, a foam strip supply part arranged on the support, and the foam strip supply part includes a translation assembly for horizontal movement and at least two Set of foam canister assemblies for storing foam strips; one side of the foam strip supply has a cutout for cutting the foam strip; the other side of the foam strip supply has a cutout for pushing the foam strip into The step pushing part of the component; one side of the step pushing part is provided with a foam strip pushing part for pushing the cut foam strip into the hollow elevator guide rail. The present invention adopts multiple groups of foam can components to be used alternately, avoiding problems such as low production efficiency caused by stopping the machine to replenish foam strips, and a single foam can component only corresponds to one motor drive, which simplifies the equipment structure; cutting, chamfering, filling the entire The process is fully automated, the labor intensity of workers is small, and the production efficiency is high.

Description

technical field [0001] The invention relates to production equipment for a hollow elevator guide rail assembly, in particular to a hollow guide rail foam strip stuffing device with double foam cans and a working method. Background technique [0002] The elevator guide rail is an elevator component composed of steel rails and connecting plates. Existing guide rails can be divided into three types: T-shaped, L-shaped and hollow from the cross-sectional shape. Since the hollow elevator guide rail has a series of advantages such as light weight and material saving, it is widely used. Hollow elevator guide rails are generally filled with foam inside to make them have the performance of sound insulation, noise reduction and shock absorption. Most of the existing foam filling is carried out manually. In this kind of operation, workers need to repeat the same mechanical action all the time. Not only is the labor load large, the work efficiency of the workers is low, and the produc...

Problems solved by technology

Most of the existing foam filling is carried out manually. In this kind of operation, the workers need to repeat the same mechanical action all the time. Not only is the labor load large, the work efficiency of the workers is low, and the product quality cannot be guaranteed to reach a uniform standard.

[0003] The hollow elevator guide rail foam filling equipment and filling method patent with the publication number CN109533927A discloses a foam strip filling mechanism for encapsulating the foam strip at the end of the elevator guide rail. The grasped foam strips cannot keep the correct posture, and it is difficult to accurately send the foam strips into the foam strip guide rail; (2) Even if the foam strip is sent into the foam strip guide rail by increasing the cross section of the foam strip guide rail, the It is impossible to ensure that the foam strip maintains an accurate posture on the foam strip guide rail, and the longitudinal slide cannot drive the push plate to push the foam strip into the cutting and profiling track; (3) In order to put the foam strip into the foam strip guide rail, the foam strip guide rail must be It is an open type. Since there is no pressure plate, the foam strip can easily run out of the foam strip guide rail during the process of being pushed into the cutting profiling track, so that the foam strip cannot be pushed into the cutting profiling track; (4) due to the pressure capacity of the foam strip Smaller, in the process of grabbing the foam strip, if the clamping force is too large, the foam strip will be crushed; if the clamping force is too small, it will easily fall off when the foam strip moves to the top of the foam strip guide rail; (5) the foam strip The cutting device can only cut off the foam strips, but cannot chamfer the foam strips, and the foam strips without chamfers are difficult to be pushed into the hollow elevator guide rail; (6) It is necessary to stop the machine to replenish the foam strips during the operation, resulting in low production efficiency
