Description

Technical Field

[0001] The utility model relates to the technical field of circular looms, in particular to an edge-cutting hot cutting knife for circular looms. Background Art

[0002] Since the cloth woven by the circular loom is a cylindrical plastic cloth, it is necessary to use a cutter to cut the plastic cloth into long strips. At the same time, since ordinary cutters will cause uneven cut edges when cutting circular loom cloth, making subsequent processing difficult, using a hot cutter for cutting is smoother and has fewer burrs.

[0003] Existing hot cutters can only achieve direct high temperature or shut down, and cannot control the temperature by increasing or decreasing the voltage through the transformer, nor can they cut stably and synchronously on both sides. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a fixed and stable edge cutting hot cutter which can control the temperature of the hot cutter through a transformer and can cut the fabric on the circular loom from both sides at the same time, in response to the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: a circular loom edge cutting hot cutter, including a voltage-adjustable transformer, the transformer is connected to two groups of hot cutter assemblies through wires, the two groups of hot cutter assemblies are arranged on the circular loom opposite to each other, the hot cutter assembly includes a knife seat, and the two ends of the knife seat in the length direction are provided with connecting ears for fixing the knife seat on the circular loom, one side of the knife seat in the width direction is provided with a pair of wire clamping blocks for the wire to abut and limit, a wire clamping plate is fixed above the wire clamping block, and the other side of the knife seat in the width direction is provided with a wiring frame for the positive and negative poles of the wire to be connected respectively, the wiring frame is provided with a first knife holder and a second knife holder corresponding to the positive and negative poles of the wire respectively at one end away from the wire, and the first knife holder and the second knife holder are fixed with hot cutters, the transformer pressurizes and increases the temperature of the hot cutter, so that the circular loom fabric is cut synchronously on both sides.

[0006] By adopting the above technical solution, the transformer can be connected to four wires, two positive wires and two negative wires. Each group of positive and negative wires is just connected to a group of hot cutting knife assemblies. The wires are limited by being embedded between the two wire clamping blocks, and the wire clamping plates are fixed by bolts to achieve more stable positioning. After the wires pass through the wire clamping blocks, the positive and negative poles are respectively connected to the first knife holder and the second knife holder. The first knife holder and the second knife holder are electrically conductive through the hot cutting knife to heat the hot cutting knife. The hot cutting knife assemblies can be installed on the circular loom on the left and right sides through the connecting ears. When the circular loom conveys the plastic cloth, the hot cutting knife extends into the plastic cloth and hot cuts both sides of the plastic cloth. In this way, the two sides of the cut plastic cloth are more symmetrical. At the same time, the hot cutting knife assembly can be fixed more stably by setting the connecting ears. Fixing the hot cutting knife by bolting the first knife holder and the second knife holder at the same time can also make the hot cutting knife not easily deformed during cutting, thereby making the cutting trajectory straighter and the opening edge of the plastic cloth more beautiful.

[0007] A circular loom edge cutting hot cutter can be further configured as follows: the hot cutter is a nickel-chromium electric heating blade, the hot cutter includes a cutter head and a blade body, the blade body is provided with a slot, the blade body is separated into a first blade body and a second blade body by the slot, the first blade body is fixed on a first blade holder and corresponds to the positive pole of the wire, and the second blade body is fixed on a second blade holder and corresponds to the negative pole of the wire.

[0008] By adopting the above technical solution, the blade body is separated by slotting, so that the first blade body is fixed to the first blade holder by bolts and connected to the positive wire, and the second blade body is also fixed to the second blade holder by bolts and connected to the negative wire. The positive wire and the negative wire conduct electricity through the blade body, thereby increasing the temperature of the blade body surface. The hot cutting knife is a nickel-chromium electric heating blade that can better adapt to changes in high and low temperatures. The blade body material is not easily affected when conducting electricity. By fixing the two sections of the blade body separately, its stability during cutting is increased.

[0009] A circular loom edge cutting knife can be further configured as follows: the wiring frame is convex-shaped, with both ends of its length direction fixed on the knife seat, and the wiring frame is provided with a first wiring hole corresponding to the first knife holder and a second wiring hole corresponding to the second knife holder at one end facing the conductor.

[0010] With the above technical solution, the first wiring hole is used for the positive wire to be inserted and fixed, and the second wiring hole is used for the negative wire to be inserted and fixed. The knife holders are connected by a hot cutter, so when the hot cutter is not installed, the two will not conduct electricity, thereby increasing safety during use.

[0011] A circular loom edge cutting hot cutter can be further configured as follows: the connecting ear is provided with a long slot along the width direction of the knife seat, and the knife seat fixes both ends of the knife seat in the length direction to the circular loom through the long slot.

[0012] Using the above technical solution, the connecting ears are used to increase the fitting area between the knife holder and the circular loom, and the long grooves allow the distance between the two sets of knife holders to be expanded or reduced when the two sets of knife holders are installed relative to each other, so that the installed knife holders can be adjusted at any time, increasing the adaptability to circular loom fabrics of different widths and having a wider range of applications.

The transformer 1 can be connected to four wires 2, two positive wires 2, and two negative wires 2. Each set of positive and negative wires 2 is just connected to a set of hot cutter assemblies 3. The two sets of hot cutter assemblies 3 are oppositely arranged on the circular loom, as shown in FIG. Figure 2 As shown, the hot cutting knife assembly 3 includes a knife seat 31, and connecting ears 32 for fixing the knife seat 31 on the circular loom are provided at both ends of the knife seat 31 in the length direction. The connecting ears 32 are provided with long slots 33 along the width direction of the knife seat 31. The knife seat 31 fixes both ends of the knife seat 31 in the length direction to the circular loom through the long slots 33. The hot cutting knife assembly 3 can be installed on the circular loom on the left and right sides through the connecting ears 32. The setting of the connecting ears 32 can more stably fix the hot cutting knife assembly 3, so that the cutting trajectory is straighter and the edge of the plastic cloth is more beautiful. The connecting ears 32 are used to increase the fitting area between the knife seat 31 and the circular loom, and the long slots 33 can expand or reduce the distance between the two groups of knife seats 31 when the two groups of knife seats 31 are relatively installed, so that the installation of the knife seat 31 can be adjusted at any time, which increases the adaptability to circular loom fabrics of different widths and has a wider range of applications. Figure 3 As shown, one side of the width direction of the knife seat 31 is provided with a pair of wire clamping blocks 34 for the wire 2 to abut and limit, and a wire clamping plate 35 is fixed above the wire clamping block 34. The other side of the width direction of the knife seat 31 is provided with a wiring rack 36 for the positive and negative poles of the wire 2 to be connected respectively. The wiring rack 36 is provided with a first knife holder 11 and a second knife holder 12 corresponding to the positive and negative poles of the wire 2 respectively at one end away from the wire 2. The wire 2 is limited by being embedded between the two wire clamping blocks 34, and the wire clamping plate 35 is fixed by bolts to achieve more stable positioning, as shown in FIG. Figure 1 、 Figure 2 and Figure 4 As shown, after the wire 2 passes through the wire clamping blocks 34, the positive and negative electrodes are connected to the first knife holder 11 and the second knife holder 12 respectively. The first knife holder 11 and the second knife holder 12 are conductive through the hot cutter 15 to heat the hot cutter 15. When the circular loom conveys the plastic cloth, the hot cutter 15 extends into the plastic cloth and hot cuts both sides of the plastic cloth. The two sides of the cut plastic cloth are relatively symmetrical. The wiring rack 36 is a convex shape, and its two ends in the length direction are fixed on the knife holder 31. The wiring rack 36 is provided with a first wiring hole 13 corresponding to the first knife holder 11 and a second wiring hole 14 corresponding to the second knife holder 12 toward one end of the wire 2. The first wiring hole 13 is used for the positive wire 2 to be inserted and fixed, and the second wiring hole 14 is used for the negative wire 2 to be inserted and fixed. The first knife holder 11 and the second knife holder 12 are fixed with a hot cutter 15. The hot cutter 15 is a nickel-chromium electric heating blade, such as Figure 5As shown, the hot cutter 15 includes a cutter head 21 and a blade body 22. A slot 23 is provided on the blade body 22. The slot 23 separates the blade body 22. The hot cutter 15 is fixed to the first blade holder 11 and the second blade holder 12 by bolts at the same time, so that the hot cutter 15 is not easily deformed during cutting. The blade body 22 is separated into a first blade body 221 and a second blade body 222 by the slot 23. The first blade body 221 is fixed to the first blade holder 11 and corresponds to the positive pole of the wire 2. The second blade body 221 is fixed to the second blade holder 12 and corresponds to the negative pole of the wire 2. The first blade body 221 is fixed to the first blade holder 11 by bolts and is connected to the positive pole of the wire 2. The second blade 222 is also fixed to the second blade holder 12 by bolts and connected to the negative wire 2. The positive wire 2 and the negative wire 2 are conductive through the blade body 22, so that the surface of the blade body 22 is heated. The hot cutter 15 is a nickel-chromium electric heating blade that can better adapt to changes in high and low temperatures. When the blade body 22 is conductive, it is not easy to affect the material of the blade body 22. By fixing the two sections of the blade body 22 separately, the stability during cutting is increased. The blade holders are connected by the hot cutter 15. Therefore, when the hot cutter 15 is not installed, the two will not conduct electricity, thereby increasing safety during use. The transformer 1 pressurizes and increases the temperature of the hot cutter 15, so that the circular loom fabric is cut synchronously on both sides.
