Description

TECHNICAL FIELD

[0001] The application relates to the technical field of warp knitting machines, in particular to an electric cutting device of a sliding adjustable warp knitting machine. BACKGROUND

[0002] In the process of fabric knitting, the knitted fabric needs to be cut due to the wide width of the fabric.

[0003] Generally, the fabric is ironed open by using an electric heating wire. The existing electric heating wire is connected to a transformer through a relay for power supply and heating, and is fixed on a machine frame.

[0004] Because the width of the fabric varies, the position of the electric heating wire on the machine frame of the warp knitting machine needs to be adjusted according to the actual situation to cut fabrics of different widths. When the position of the electric heating wire is adjusted, the electric wires are entangled with each other, which is not conducive to position replacement and may be entangled with the fabric, resulting in defects affecting the cutting efficiency. CONTENT OF THE INVENTION

[0005] In order to facilitate the cutting of fabrics of different widths and improve the cutting efficiency, the application provides an electric cutting device of a sliding adjustable warp knitting machine.

[0006] The electric cutting device of the sliding adjustable warp knitting machine provided by the application adopts the following technical scheme:

[0007] The electric cutting device of the sliding adjustable warp knitting machine comprises a relay and an electric heating wire, the electric heating wire is fixed on the relay and electrically connected with the relay, further comprises a sliding rail, the sliding rail is fixed on the machine frame of the warp knitting machine, the relay is slidingly arranged on the sliding rail and reciprocally slides along the length direction of the sliding rail; the sliding rail is fixed with conductive sheets, the length direction of the conductive sheets is arranged along the length direction of the sliding rail, the end portion of the conductive sheets is used for connecting with external electric wires, and the conductive sheets are provided in two; the relay is fixed with conductive limiting blocks, the conductive limiting blocks slidingly abut on the sliding rail and simultaneously slidingly abut on the conductive sheets, the conductive limiting blocks are provided in two and correspond to the respective conductive sheets; there is a gap between the outer wall of the relay and the sliding rail.

[0008] By adopting the above technical scheme, the two conductive sheets are connected with a live wire and a zero wire respectively, and then the current path is formed by cooperating the conductive limiting blocks, the relay and the electric heating wire, so that the electric heating wire can heat and iron open the fabric to realize the cutting of the fabric. When the cutting position needs to be adjusted, the relay slides on the sliding rail to adjust the position, which not only ensures the heating of the electric heating wire, but also avoids the entanglement of the excess electric wires, so that the fabric of different widths can be cut conveniently and the cutting efficiency is improved.

[0009] Optionally, the sliding rail is hollow, the relay top end and the conductive limiting blocks are slidingly arranged in the sliding rail, and the conductive sheets are fixed on the inner wall of the sliding rail.

[0010] By adopting the technical scheme, the guide rail not only stabilizes the sliding path of the relay, but also provides a protection space for the conductive limiting block and the conductive sheet.

[0011] Optionally, the relay is fixed with a grounding limiting block for grounding at the top, the grounding limiting block is slidingly arranged on the slide rail and reciprocally slides along the length direction of the slide rail.

[0012] By adopting the technical scheme, the grounding limiting block plays a protection role for the operation of the relay, and when a circuit fault or electric leakage occurs, the electric current can be introduced into the ground, thereby protecting the safety of the operators and the equipment.

[0013] Optionally, a plurality of lower rollers are arranged on the relay, the lower rollers are used for supporting the relay and rolling on the inner wall of the bottom of the slide rail.

[0014] By adopting the technical scheme, the lower rollers play a supporting role for the relay, and ensure that there is a distance between the relay and the inner wall of the slide rail, and the rolling of the lower rollers on the slide rail can make the movement of the relay on the slide rail more smooth and light.

[0015] Optionally, a plurality of upper rollers are arranged on the relay, the upper rollers roll on the inner wall of the top of the slide rail.

[0016] By adopting the technical scheme, the upper rollers play a supporting role for the relay, and ensure that there is a distance between the relay and the inner wall of the slide rail, and the rolling of the upper rollers on the slide rail can make the movement of the relay on the slide rail more smooth and light.

[0017] Optionally, the two conductive limiting blocks are distributed on the relay in a staggered manner along the length direction of the slide rail, and only one conductive limiting block is distributed on the side wall of one side of the relay.

[0018] By adopting the technical scheme, when the two conductive limiting blocks are arranged in a staggered manner along the length direction of the slide rail, compared with being symmetrically arranged on the two sides of the relay, the probability that the two conductive limiting blocks are in contact with foreign matters and form a short circuit path at the same time due to accidental conditions (such as dust, fibers and other foreign matters entering the slide rail) during the operation of the equipment is reduced.

[0019] Optionally, the conductive sheet is made of a copper sheet.

[0020] Optionally, an insulating coating is coated on the outer wall of the slide rail.

[0021] By adopting the technical scheme, in the working environment of the warp knitting machine, the operators may frequently contact the area near the guide rail, the insulating coating can effectively prevent the conduction of the electric current to the outer wall of the guide rail, even in the case of electric leakage, the personal safety of the operators can be ensured, and the risk of electric shock is reduced.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the cutting position needs to be adjusted, the relay can be adjusted by sliding on the slide rail. With the help of the conductive sheet and conductive limit block, the heating of the heating element is ensured, and the entanglement of excess wires is avoided, so as to facilitate the cutting of fabrics of different widths and improve the cutting efficiency.

[0024] 2. The upper and lower rollers support the relay, ensuring a distance between the relay and the inner wall of the slide rail. At the same time, the rolling of the upper and lower rollers on the slide rail makes the movement of the relay on the slide rail smoother and easier.

[0025] 3. When the two conductive limit blocks are staggered along the length of the slide rail, compared with symmetrical arrangement on both sides of the relay, the probability of the two conductive limit blocks coming into contact with foreign objects and forming a short circuit due to unexpected situations (such as dust, fibers or other foreign objects entering the slide rail) during equipment operation is reduced.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0031] This application discloses an electric cutting device for a sliding adjustable warp knitting machine.

[0032] refer to Figure 1 The electric cutting device of the sliding adjustable warp knitting machine includes a slide rail 1, a relay 2, and an electric heating wire 3. The electric heating wire 3 is fixed to the relay 2 and electrically connected to the relay 2. The relay 2 is slidably mounted on the slide rail 1 and slides back and forth along the length of the slide rail 1. The slide rail 1 is fixed to the frame of the warp knitting machine.

[0033] refer to Figure 1 and Figure 2The slide rail 1 can be made of aluminum profile. The slide rail 1 is a hollow rectangular strip, placed horizontally. A notch 12 is provided on the bottom surface of the slide rail 1, extending along its length. The top of the relay 2 is located inside the slide rail 1, and the bottom end of the relay 2 passes through the notch 12, providing space for the relay 2 to slide on the slide rail 1. The outer wall of the slide rail 1 is coated with an insulating layer formed of high-temperature resistant silicone insulating varnish. The inner wall of the slide rail 1 is provided with a slide track 11 and a slot 13, both extending along the length of the slide rail 1. Two slots 13 are provided, facing each other on the vertical inner wall of the slide rail 1. The slide track 11 is fixed to the top inner wall of the slide rail 1, facing the notch 12.

[0034] refer to Figure 1 and Figure 2 The slide rail 1 is equipped with a conductive sheet 4 and a grounding terminal 9, with the grounding terminal 9 fixed at one end of the slide rail 1. Two conductive sheets 4 are provided and arranged along the length of the slide rail 1, with each conductive sheet 4 located within a slot 13. The conductive sheet 4 is made of copper and is electrically connected to an external circuit, which can be the power supply system of the warp knitting machine, transmitting electrical energy from the transformer to the copper sheet via wires.

[0035] refer to Figure 2 and Figure 3 The relay 2 is equipped with a grounding limit block 6, a conductive limit block 5, an upper roller 8, and a lower roller 7. There are two of each of these components. The two conductive limit blocks 5 are located on both sides of the relay 2 and are fixedly connected to the vertical sidewall of the relay 2. The two conductive limit blocks 5 are staggered along the length of the slide rail 1 on the relay 2. The ends of the conductive limit blocks 5 abut against the nearest conductive piece 4 and slide within the slot 13, sliding along the length of the slide rail 1. The two upper rollers 8 are located at both ends of the top of the relay 2 along the length of the slide rail 1, and the two lower rollers 7 are located at both ends of the bottom of the relay 2 along the length of the slide rail 1. The upper rollers 8 and lower rollers 7 support the outer wall of the relay 2 and create a distance between it and the inner wall of the slide rail 1, making the sliding of the relay 2 smoother. Both the upper rollers 8 and lower rollers 7 roll against the inner wall of the slide rail 1.

[0036] refer to Figure 2 and Figure 3 The grounding limit block 6 is fixed on the top of the relay 2, and the end of the grounding limit block 6 away from the relay 2 is located in the slide rail 11 and slides along the length of the slide rail 11.

[0037] refer to Figure 1 and Figure 2The grounding limit block 6 at the top of relay 2 is designed to slide directly against the slide rail 1, and a grounding terminal 9 is provided at one end of the slide rail 1 to realize the grounding function of the grounding limit block 6. However, the specific implementation method is not limited to this one. When the equipment is running normally, if leakage occurs, the current can be conducted to the slide rail 1 through conductive components (such as the housing of relay 2, grounding limit block 6, etc.), and then flow into the ground through the connection between the slide rail 1 and the grounding terminal 9, protecting the safety of operators and equipment.

[0038] The implementation principle of the electric cutting device of the sliding adjustable warp knitting machine in this application embodiment is as follows: one of the two conductive plates 4 is connected to the live wire and the other to the neutral wire. Then, together with the conductive limit block 5, the relay 2 and the heating wire 3, a current path is formed, so that the heating wire 3 can heat and scald the fabric to achieve cutting of the fabric. When it is necessary to adjust the cutting position, the relay 2 can be adjusted by sliding on the slide rail 1. This ensures the heating of the heating wire 3 and avoids the entanglement of excess wires, so as to facilitate the cutting of fabrics of different widths and improve the cutting efficiency.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
