Description

Technical Field

[0001] The utility model relates to the technical field of fabric production, in particular to a fabric embossing machine. Background Art

[0002] The hot-pressing type drum embossing machine plays a crucial role in modern textile processing. Such machines combine a heated drum with a mold with a specific pattern, applying heat and pressure to the fabric surface, thereby forming durable and beautiful patterns on the fabric. In the existing technology, the embossing machine usually includes one or more pairs of drums, at least one of which is heated to the required temperature, while the other drum or mold carries the required texture pattern. The fabric passes between the two drums, and while being heated and pressed, the pattern is accurately transferred to the fabric.

[0003] Although the current technology has been able to achieve the pressing of patterns with a single depth and intensity, if different depths of patterns need to be formed on the same fabric simultaneously, the existing embossing machines face certain technical limitations. The traditional method often requires multiple embossing operations on the same fabric, only processing part of the pattern each time, and achieving different depth effects by changing the temperature and pressure settings. This method not only has complex procedures, is time-consuming and laborious, but also increases the risk of damage to the fabric during repeated heating and cooling processes. Summary of the Utility Model

[0004] Aiming at the deficiencies in the existing technology, the utility model provides a fabric embossing machine, which solves the technical problem that the existing fabric embossing machine cannot emboss patterns with different depths on the fabric simultaneously.

[0005] A fabric embossing machine according to an embodiment of the utility model includes an embossing roller and a driving motor for driving the embossing roller. Electric heating wires are evenly distributed inside the embossing roller along the length direction of the embossing roller, and each section of the electric heating wire is fixed in a spiral shape on the inner side of the embossing roller;

[0006] All the electric heating wires are connected in parallel with each other, all the electric heating wires are connected to a common main power supply, a resistor is connected in series at one end of each section of the electric heating wire close to the main power supply, and all the resistors are also connected in parallel with each other. The resistance values of all the resistors are at least two kinds.

[0007] The technical principle of the utility model is as follows: when in use, all the electric heating wires are connected to the main power supply, and then according to the patterns with different depths on the fabric, resistors with different resistance values are set. The electric heating wires at the positions of the shallow patterns are connected to resistors with large resistance values, and the resistance values of the resistors connected to the electric heating wires at the positions of the slightly deeper patterns are smaller than those of the resistors at the positions of the shallow patterns, and so on. By setting different resistance values of the resistors, various patterns with different depths can be hot-pressed simultaneously.

[0008] Compared with the prior art, the utility model has the following beneficial effects: by evenly distributing the heating wires and matching them with the resistors connected in series, the fabric with various light and deep patterns can be hot-pressed simultaneously, which solves the technical problem that the fabric embossing machine in the prior art cannot emboss the fabric with different light and deep patterns at the same time.

[0009] Further, a sub-control switch is connected in series at one end of all the resistors close to the main power supply, and a common main switch is arranged between all the sub-control switches and the main power supply.

[0010] Further, all the sub-control switches are temperature control switches, and the temperature sensing heads of the sub-control switches are arranged between the heating wires connected in series to measure the temperature of the series-connected heating wires.

[0011] Further, all the resistors, the sub-control switches and the main switch are integrated on a control panel.

[0012] Further, the resistor is a variable resistor.

[0013] Further, the embossing roller includes an outer drum and an inner fixed cylinder. The inner fixed cylinder is arranged inside the outer drum, and the opening of the inner fixed cylinder is arranged at the bottom of the outer drum. The bottom of the inner fixed cylinder is arranged at the opening of the outer drum. There is a bearing connection between the outer cylindrical surface of the inner fixed cylinder and the inner cylindrical surface of the outer drum. All the heating wires are arranged on the inner wall of the inner fixed cylinder, and the driving motor is connected to the outer drum.

[0014] Further, a connecting pipe is arranged at one end of the inner fixed cylinder close to the bottom. The center of the connecting pipe penetrates through the inside of the inner fixed cylinder, and the heating wires are connected to the main power supply by wire through the connecting pipe.

[0015] Further, a connecting shaft is arranged at the center of one end of the outer drum close to the bottom, and the connecting shaft is drivingly connected to the driving motor.

[0016] Further, support frames are arranged at both the connecting pipe and the connecting shaft. Description of the Drawings

DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figure 1 The fabric embossing machine shown includes an embossing roller 100 and a driving motor 101 for driving the embossing roller 100. Specifically, the embossing roller 100 includes an outer cylinder 110 and an inner fixed cylinder 120, wherein the inner fixed cylinder 120 is arranged in the outer cylinder 110, and the opening of the inner fixed cylinder 120 is arranged at the bottom of the outer cylinder 110, and the bottom of the inner fixed cylinder 120 is arranged at the opening of the outer cylinder 110. A bearing 121 is provided between the outer cylindrical surface of the inner fixed cylinder 120 and the inner cylindrical surface of the outer cylinder 110 for connection. The bearing 121 here is embedded in the surface of the inner fixed cylinder 120, so that the outer cylindrical surface of the inner fixed cylinder 120 and the inner cylindrical surface of the outer cylinder 110 are in a close state, which is convenient for heat conduction and ensures that when the outer cylinder 110 rotates, the inner fixed cylinder will not rotate with it. The driving motor 101 is connected to the outer cylinder 110 to provide driving force to the outer cylinder 110.

[0024] like Figure 1 As shown, a connecting shaft 111 is fixed at the center of one end of the outer drum 110 near the bottom, and the connecting shaft 111 is connected to the drive motor 101 for transmission. A connecting pipe 122 is fixed at one end of the inner fixed cylinder 120 near the bottom. A supporting frame 130 is provided at the connecting pipe 122 and the connecting shaft 111 for supporting the entire fabric embossing machine.

[0025] like Figure 1 As shown, the inner wall of the inner fixed cylinder 120 is evenly distributed with heating wires 140 along the length direction of the embossing roller 100, and each section of the heating wire 140 is spirally fixed to the inner wall of the inner fixed cylinder 120 to ensure that the heating wire 140 is in a fixed and non-rotating state, and its heat is transferred to the outer cylinder 110 through the inner fixed cylinder 120.

[0026] like Figure 1-2As shown, all the heating wires 140 are connected in parallel with each other. The connecting pipe 122 penetrates through the center of the inner fixing cylinder 120. All the heating wires 140 are wired-connected to a common main power supply 300 through the connecting pipe 122. A resistor 210 is connected in series at one end of each heating wire 140 close to the main power supply 300. All the resistors 210 are also connected in parallel with each other. The resistance values of all the resistors 210 are at least two kinds, so that the heating efficiencies of the heating wires 140 connected in series with resistors 210 of different resistance values are different, thereby ensuring that the temperatures on the outer surface of the outer drum 110 are different, and different depths of patterns can be embossed on the fabric.

[0027] As Figure 2 shown, a sub-control switch 220 is connected in series at one end of each resistor 210 close to the main power supply 300. A common main switch 230 is provided between all the sub-control switches 220 and the main power supply 300. The main switch 230 is used to control the power-on and power-off of all the heating wires 140, while the sub-control switch 220 is used to control the power-on and power-off of the heating wire 140 connected in series therewith. Thus, the operator can turn on or off the sub-control switch 220 or the main switch 230 according to actual needs.

[0028] As Figure 1 shown, all the resistors 210, the sub-control switches 220 and the main switch 230 are integrated on a control panel 200, which is convenient for maintenance and use.

[0029] Embodiment 2

[0030] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that: all the sub-control switches 220 are temperature control switches, and the temperature sensing heads 221 of the sub-control switches 220 are all arranged between the heating wires 140 connected in series with the sub-control switches 220 for measuring the temperature of the heating wires 140 connected in series.

[0031] Embodiment 3

[0032] The difference between this embodiment and Embodiments 1-2 is that: the resistor 210 is a variable resistor 210, and the resistance value of the resistor 210 can be flexibly changed, thereby changing the heating efficiency of the heating wire 140. Combining Embodiment 2 with this embodiment, intelligent embossing control can be realized in cooperation with the control system.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
