Abstract
The utility model discloses an automatic speed reducer for a sewing machine processing excessively thick sewing materials, comprising a machine head and a presser bar installed in the machine head, wherein a sensor is connected on the presser bar; the change of position of the presser bar, which is detected by the sensor, is converted into thickness signals which are then transmitted to a computer controller; and the preset deceleration numerical value is called by the computer controller according to different thickness signals. Through the arrangement of the sensor, the automatic speed reducer can detect the change of position of the presser bar in a production process and automatically regulate the rotating speed of the sewing machine by matching the range of speed regulation preset through the computer controller with the thickness signals transmitted, thus preventing the accidents of broken lines, skipping stitches or broken needles, and having the advantages of reasonable structure, high production efficiency and product quality, and the like.
Description
Technical field
The utility model discloses the blocked up automatic slow-down device of a kind of Sewing machines sewing, divides by International Patent Classification (IPC) (IPC) to belong to Sewing machines related accessory manufacturing technology field.
Background technology
Sewing machines is to use one or more sewing thread, forms one or more stitchings, the machine that makes one or more layers sewing interweave or unite by a seam on sewing.Along with the deep application of electronic technology in garment machinery, Sewing machines is also made the transition to Based Intelligent Control by complete hand-guided type, and computer controlled sewing machine is exactly the Sewing machines of a class by computer or other intelligent processor automations control.
Existing computer driving Sewing machines all standard configuration has electrically-actuated throttle device; the user can carry out manual governing according to the quality and the process requirements of sewing; so; in the reality use, running into the workpiece of making through regular meeting can be in thickening suddenly somewhere, and the dealer is referred to as " crossing stalk " usually; the thickness of this position can exceed the thickness that this seam speed can be born down; and causing phenomenons such as broken string, bouncing pilotage to take place, severe patient even the broken needle phenomenon occurs has influence on normally carrying out of the work of making.
The broken string, bouncing pilotage or the broken needle phenomenon that solve above-mentioned " crossing stalk " and cause, experienced sewing operation personnel, can " cross stalk " preceding take to slow down make, but this method of operating to the operator, and sewing technology have relatively high expectations, even experienced sewing operation personnel can not time time " crossing stalk " be slowed down when taking place in advance, therefore still there are broken string, bouncing pilotage or broken needle phenomenon to occur, and be difficult to avoid the generation of above-mentioned phenomenon especially for inexperienced new hand, in case broken string, bouncing pilotage or broken needle accident occur, can reduce production efficiency undoubtedly, and then increase production cost.
For these reasons, the inventor thinks that when crossing stalk machine can detect workpiece and cross the thickness at stalk place and in time adjust sewing speed, and replaces existing manual mode of operation, to the production efficiency and the quality of production a large amount of must rising can be arranged all.
The utility model content
At the deficiencies in the prior art, the utility model provides a kind of blocked up automatic slow-down device of Sewing machines sewing rational in infrastructure, easy to use.
For achieving the above object, the utility model is achieved through the following technical solutions:
The blocked up automatic slow-down device of a kind of Sewing machines sewing, comprise head and be installed on the interior presser bar of head, wherein, connect sensor on the described presser bar, this sensor to the presser bar position variation and change into thickness signal and be transported to computer controller, computer controller calls predefined deceleration numerical value according to different thickness signals.
Further, described sensor is a position sensor, and what this position sensor was direct or indirect is fixed on presser bar.
Further, described position sensor links to each other with presser bar by contiguous block, and presser bar is arranged in contiguous block and affixed with it, and position sensor is fastened on the contiguous block.
Further, described contiguous block side connects jack, and this jack and contiguous block contact-making surface are step-like, match with the ledge structure of contiguous block side.
The thinking of the utility model design is as follows: directly and the position of sewing thickness associated, a sensor has been installed on the presser bar, because the displacement that the presser feet on presser bar top moves up and down can reflect the thickness of sewing, this sensor can detect the change in location of presser bar in process of production, calculate the sewing thickness of workpiece according to the amount that changes, and sending the signal of a respective thickness to control system, pre-set deceleration numerical value can call according to the different-thickness signal in system.Different-thickness adapts to different rotating speeds, can be by the professional in advance according to different factories different product structural adjustment preset value.
Setting by the utility model sensor, can detect the change in location of presser bar in process of production, and then the thickness signal that the speed adjustable range that sets in advance by computer controller and sensor are carried is corresponding, automatically adjust the rotating speed of Sewing machines, avoid occurring broken string, bouncing pilotage or broken needle accident, have rational in infrastructure, production efficiency is high, the product quality advantages of higher.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the local figure of the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: see also Fig. 1 and Fig. 2, the blocked up automatic slow-down device of a kind of Sewing machines sewing, comprise head 1 and be installed on presser bar 2 in the head 1, wherein, connect sensor 3 on the described presser bar 2, the variation of these sensor 3 detected presser bar positions and change into thickness signal and be transported to computer controller, computer controller calls predefined deceleration numerical value according to different thickness signals.
See also Fig. 2, described sensor is a position sensor 3, and what this position sensor was direct or indirect is fixed on presser bar 2.
See also Fig. 2, described position sensor 3 links to each other with presser bar 2 by contiguous block 4, and presser bar 2 is arranged in contiguous block 4 and affixed with it, and position sensor 3 is fastened on the contiguous block 4.
See also Fig. 2, described contiguous block 4 sides connect jack 5, and it is step-like 51 that this jack 5 and contiguous block contact-making surface are, and matches with the ledge structure of contiguous block 4 sides.
The thinking of the utility model design: set out in position direct and sewing thickness associated, select on the presser bar sensor to be installed, because the displacement that the presser feet on presser bar top moves up and down can reflect the thickness of sewing, this sensor can detect the change in location of presser bar in process of production, calculate the sewing thickness of workpiece according to the amount that changes, and sending the signal of a respective thickness to control system, pre-set deceleration numerical value can call according to the different-thickness signal in system.Different-thickness adapts to different rotating speeds, can be by the professional in advance according to different factories different product structural adjustment preset value.
The above record only for utilizing the embodiment of this origination techniques content, anyly is familiar with modification, the variation that this skill person uses this creation to do, and all belongs to the claim of this creation opinion, and is not limited to those disclosed embodiments.
