Description

Stamping and ironing sheet assembly

Technical Field

The invention relates to a stamping and ironing sheet assembly which is mainly applied to the technical field of ironing sheets.

Background

In the embroidery industry, the ironing process of embroidery cloth is widely applied to clothes, industrial art articles and toys by virtue of beautiful visual effects with bright color and luster, and at present, a piece ironing machine is usually used for processing the ironing piece to complete partial steps in the ironing process. For example, prior art publication No. CN111910353A discloses a die combination sheet ironing machine head and punch pin buffer mechanism cooperation structure and sheet ironing machine, specifically discloses: when the punch needle driving rod punches downwards, the punch needle mounting seat 35 is driven, the punch needle mounting seat 35 drives the punch needle 36 to move downwards, the punch needle passes through the punch needle guide hole in the punch needle base fixing block 33 and the blanking hole 321 in the punch needle guide seat 32, the punch needle passes through the lower part of the punch needle base 31, the material belt where the material sheet is located passes through the sheet passing groove 322 in the middle of the punch needle guide seat 32, the material sheet with the corresponding specification size is punched by the punch needle 36, a certain distance is punched under the punch needle base 31, and the material belt is adhered to the paster on the special rubber plate. During the lifting process, the punch pin 36 is lifted under the dual action of the punch pin driving rod and the punch pin return spring 37.

One side of the film tape (material tape) is embroidered, the other side is a sticky surface, the sticky surface is smooth at normal temperature, the film tape in the punching mechanism is punched, the embroidered surface faces downwards and the sticky surface faces upwards, the embroidered surface of the diaphragm punched by the punching needle is stuck on the sticker, and the following steps are required to be implemented after the film punching machine is used for completing the punching of the diaphragm: flatly pressing the paster on the embroidery cloth, pasting the pasting surface of the membrane on the surface of the embroidery cloth, then melting the pasting surface by using a hot-pressing process to paste the membrane on the surface of the embroidery cloth, and tearing the paster off the embroidery cloth to finish the whole process because the pasting strength of the pasting surface is greater than that of the paster.

Therefore, this prior art technique has drawbacks: firstly, the whole process flow of the stamping and ironing sheet is complex, four main steps of stamping and ironing sheet-paster flat laying embroidery cloth-hot pressing ironing sheet-paster embroidery cloth separation are needed, small auxiliary steps are also inserted among the four main steps, the steps are complex, the working efficiency is influenced, the optimization difficulty of the process is high, and the optimization means aiming at the process flow is relatively few. Secondly, the two steps of punching the film sheet and ironing the sheet are mutually independent and need to be separately implemented, the process continuity is poor, when a manufacturer actually operates, firstly, the stickers in a production batch are concentrated to complete the pasting and the pressing of the film sheet, then, the stickers in the batch are flatly laid on the embroidery cloth to be subjected to hot pressing and ironing, the time interval between the two steps is long, the pasting surface of the sticker is very easy to adhere dust, impurities and the like, so that the sticker needs to be placed in a dust-free space or storage equipment, and the requirements on the storage and the protection of the sticker are improved; moreover, for the process steps of the embroidery cloth hot pressing and ironing, in addition to the ironing machine, a hot press needs to be additionally arranged and manpower is also needed, and the cost is relatively high.

Disclosure of Invention

The invention aims to provide a stamping and ironing sheet assembly, which improves the stamping efficiency.

The invention is realized by the following technical scheme.

A stamped iron sheet assembly comprising:

the stamping assembly comprises a stamping guide rod and a stamping needle which are vertically arranged, and the bottom end of the stamping guide rod is connected with the top end of the stamping needle;

the driving device is used for driving the stamping guide rod to reciprocate along the axial direction of the stamping guide rod;

a punch seat located below the punch assembly, the punch seat allowing a membrane strip to pass through and be punched out of a membrane by the punch pin;

further comprising:

and the ultrasonic welding machine is positioned below the stamping seat, and the welding head of the ultrasonic welding machine is over against the stamping needle.

Different from the prior art, in the application environment of the invention, the membrane belt in the punching seat has an embroidery face upward and a sticking face downward, before the membrane belt is used, the embroidery cloth is firstly paved on a welding head of an ultrasonic welding machine, the membrane belt is punched by a punching needle after a driving device is started, the punched membrane is pressed on the embroidery cloth and is matched with the welding head to tightly press the membrane and the embroidery cloth, at the moment, the sticking face of the membrane is stuck on the surface of the embroidery cloth, and under the action of the ultrasonic welding machine, the high-frequency mechanical vibration acted on the sticking face quickly raises the temperature of the membrane belt and melts the membrane belt, and then the membrane belt is stuck on the surface of the embroidery cloth, so that the two steps of punching and ironing are synchronously completed.

Firstly, in the process of stamping the iron sheet, the stamping needle not only can stamp the iron sheet, but also can be matched with a welding head of an ultrasonic welding machine to compress the membrane and the embroidery cloth, so that the ultrasonic welding process is completed. Secondly, the welding speed of ultrasonic welding is very fast and can be finished within 0.1-0.5 s, the ultra-high speed welding process only melts the pasting surface of the membrane, the embroidery cloth cannot be affected, and the efficiency of ironing the membrane is higher. Moreover, compared with a hot pressing process, the ultrasonic welding process has the advantages that the ultrasonic welding effect is better, the bonding strength between the membrane and the embroidery cloth is higher, and the membrane on the surface of the embroidery cloth is not easy to turn over or even fall off.

As a further improvement of the present invention, the stamping assembly further includes an elastic resetting member, a gap extending along the vertical direction is provided between the stamping guide rod and the stamping needle, and the elastic resetting member and the gap are compressed synchronously when the stamping guide rod and the stamping needle are displaced relatively.

The principle of ultrasonic welding is that high-frequency mechanical vibration is generated on materials, a welding head needs to be in close contact with the materials, pressure with certain strength is applied to a membrane belt and cloth by stamping, and in practical application, if the stamping is in rigid contact with the membrane, the stamping is limited by processing fineness and part tolerance, embroidery cloth with different thicknesses and membranes with different thicknesses, the requirement of high precision is hardly met when a stamping guide rod and a stamping needle are located at the lowest position of a stroke, the situation that the pressure applied to the membrane by the stamping is too small or even the membrane cannot be tightly pressed on the cloth due to the fact that the lowest position of the stroke is too high easily occurs, or the situation that the embroidery cloth is broken due to the fact that the applied pressure is too large due to the fact that the lowest position of the stroke is.

Therefore, the gap is arranged between the stamping guide rod and the stamping needle and the elastic reset piece is arranged, so that the problem can be solved, when the stamping needle moves downwards, the diaphragm is just pressed on the surface of the embroidery cloth, at the moment, the stamping guide rod is not at the lowest position, the gap between the stamping needle and the stamping guide rod and the elastic reset piece are gradually compressed, the stamping needle is not in rigid contact but in elastic contact with the diaphragm under the action of the elastic force of the elastic reset piece, and the pressure of the stamping needle on the film belt is gradually increased along with the continuous descending of the stamping guide rod, so that the pressure applied by the stamping needle can meet the requirement of ultrasonic welding, the problem that the embroidery cloth is crushed due to overlarge pressure can be avoided, and the gap between the stamping guide rod and the stamping needle cannot be completely consumed in the process, so that the elastic contact is converted into rigid contact.

In the prior art, the position and time of a stamping needle are taken as coordinate axes, the moving track of a stamping guide rod is a sine curve, and a wave trough corresponds to the lowest stroke position of the stamping needle, so that the stamping needle rapidly rises after falling to the lowest stroke position, the state that the stamping needle tightly presses a membrane on a sticker is maintained for only one moment, and the sticking firmness is not ideal.

In addition, when the punching needle punches the membrane strip in the punching seat, firstly, the punching needle is in elastic contact with the membrane strip, the membrane strip cannot be punched due to too small pressure, when the gap is compressed to zero, the elastic contact is converted into rigid contact, and the punching needle punches the membrane strip and takes the membrane out.

In summary, in the punching process, the punching pins are in rigid contact when punching the film strip and in elastic contact when pressing the film against the cloth.

Referring to fig. 4-6, the driving device 4 includes a main shaft 41, a fixed shaft 42, a cam 43, a swinging structure 44, and a transmission mechanism 45, wherein the main shaft 41 and the fixed shaft 42 are horizontally disposed, the cam 43 is sleeved on the main shaft 41, the swinging structure 44 is slidably sleeved on the fixed shaft 42 and has one end connected to the cam 43, and the transmission mechanism 45 drivingly connects the swinging structure 44 to the punch guide rod 11.

One end surface of the cam 43 is provided with an annular groove G around the rotation center of the cam 43, the annular groove G comprises a first eccentric arc section G1, a concentric arc section G3 and a second eccentric arc section G2 by taking the rotation center of the cam 43 as reference, one end of the first eccentric arc section G1 and one end of the second eccentric arc section G2 are connected with two ends of the concentric arc section G3, and the first eccentric arc segment G1 and the second eccentric arc segment G2 are symmetrical about the rotation center of the cam 43, the other ends of the first eccentric arc segment G1 and the second eccentric arc segment G2 can be directly connected, or an arc segment can be arranged between the two, one end of the swing structure 44 is provided with a rolling element 441, the rolling member 441 is slidably engaged with the annular groove G, in this embodiment, the distance from the concentric arc section G3 to the rotation center of the cam 43 is the largest in the annular groove G, the cam 43 rotates with the main shaft 41, and the punch guide 11 is located at the lowest stroke position when the rolling member 441 slides in the annular groove G to the concentric arc section G3. In another embodiment, the distance from the concentric arc segment G3 to the center of rotation of the cam 43 is the smallest in the annular groove G, and the punch guide 11 is also located at the lowest position of travel when the roller 441 slides in the annular groove G to the concentric arc segment G3. Both embodiments are possible, and only the corresponding adjustment of the swing structure 44 and the transmission mechanism 45 is required.

The first eccentric arc segment G1/the second eccentric arc segment G2 gradually decreases or increases from the distance between one end of the engaging concentric arc segment G3 and the rotation center of the cam 43 to the other end, and the sliding process of the rolling element 441 in the first eccentric arc segment G1/the second eccentric arc segment G2 corresponds to the descending/ascending of the punch guide rod 11 from the highest stroke to the lowest stroke.
