Description

Technical Field

[0001] The utility model relates to a webbing production device, in particular to a shaping machine for webbing production. Background Art

[0002] The shaping machine is mainly used for shaping and finishing of fabrics, so as to keep the shape of thermoplastic fibers and blended or interwoven fabrics stable and improve the dimensional stability of fabrics. Ribbon is a narrow or tubular fabric made of various yarns. Similar to conventional fabrics, it also needs shaping and finishing.

[0003] The traditional heating setting machine heats and sets the ribbon through the heating roller. When the equipment stops, the heating roller is still hot and contacts with one side of the ribbon for a long time, which will cause the contact surface between the ribbon and the heating roller to be burned due to long-term heating. In order to solve the above problem, the utility model proposes a new improvement plan. Summary of the invention

[0004] The utility model provides a shaping machine for ribbon production, which solves the problem in the prior art that the ribbon is damaged by long-term contact with a heating roller when the shaping equipment stops running.

In the utility model, the two electric heating pipes and the two linear drives are controlled and operated by the PLC control center.

[0006] When the utility model is in a production state, the first electric heating tube and the second electric heating tube are always located in the first arc-shaped sheet and the second arc-shaped sheet under the action of the first linear drive and the second linear drive, and the two electric heating tubes are in an energized heating state, and the heat generated by the two electric heating tubes can be directly transferred to the two arc-shaped sheets by means of thermal radiation, and the webbing flowing through the utility model slides over the outer arc surfaces of the first arc-shaped sheet and the second arc-shaped sheet in sequence in a taut state, so that both sides of the webbing will be heated and shaped; when the utility model is urgently stopped or the production operation is stopped, the two electric heating tubes will be powered off, and at the same time, the first linear drive and the second linear drive will push the two heating seats to move in opposite directions, so that the first electric heating tube moves out of the first arc-shaped sheet, and the second electric heating tube moves out of the second arc-shaped sheet, so that the residual heat on the electric heating tubes will not continue to heat the arc-shaped sheet, and the arc-shaped sheet itself is a metal sheet, and its own heat will be quickly dissipated after losing the heating of the electric heating tube, so that the webbing is not easily scalded.

[0007] Furthermore, a feed guide roller and a discharge guide roller are rotatably connected between the two positioning plates, the feed guide roller is located at the front side of the first arc-shaped piece, and the discharge guide roller is located at the rear side of the second arc-shaped piece, the opening of the first arc-shaped piece is set upward, and the opening of the second arc-shaped piece is set downward. The feed guide roller and the discharge guide roller are used to guide the webbing to flow through the first arc-shaped piece and the second arc-shaped piece in sequence at a fixed angle.

[0008] Furthermore, the feed guide roller is provided with a plurality of first annular grooves arranged at equal intervals, and the discharge guide roller is provided with second annular grooves corresponding to the first annular grooves one by one. Both annular grooves are used to guide and position the webbing, and their width is slightly larger than the width of the webbing.

[0009] Therefore, compared with the prior art, the present invention has the following characteristics: 1. When the present invention stops suddenly or stops production, the two electric heating tubes will be powered off, and at the same time, the first linear drive and the second linear drive will push the two heating seats to move in opposite directions, so that the two electric heating tubes move out of the arc-shaped sheet. In this way, the residual heat on the electric heating tubes will not continue to heat the arc-shaped sheet. After losing the heating of the electric heating tubes, their own heat will be quickly dissipated, so that the ribbon is not easily burned. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Example 1: See Figure 1 , Figure 4 and Figure 5 A shaping machine for ribbon production, comprising two positioning plates 100 arranged parallel to each other and spaced apart, four positioning rods 110 are connected and fixed between the two positioning plates, a first arc-shaped piece 200 is fixed between two adjacent positioning rods, a second arc-shaped piece 300 is fixed between the other two adjacent positioning rods, both ends of the two arc-shaped pieces are spaced apart from the two positioning plates, a feed guide roller 401 and a discharge guide roller 402 are rotatably connected between the two positioning plates, the feed guide roller is located at the front side of the first arc-shaped piece, the discharge guide roller is located at the rear side of the second arc-shaped piece, the opening of the first arc-shaped piece is arranged upward, and the opening of the second arc-shaped piece is arranged downward;

[0018] Two first slide rails 120 and two second slide rails 130 are vertically provided on the two positioning plates respectively. A first sliding seat 140 is slidably matched on each of the two first slide rails on the same side, and a second sliding seat 150 is slidably matched on each of the two second slide rails on the same side. A first heating seat 160 is connected between the two first sliding seats, and a first electric heating tube 170 is provided on the first heating seat. A second heating seat 180 is connected between the two second sliding seats, and a second electric heating tube 190 is provided on the second heating seat. A first linear drive 501 that drives the first sliding seat to slide back and forth and a second linear drive 502 that drives the second sliding seat to slide back and forth are also provided on the positioning plate; the first sliding seat can drive the first electric heating tube thereon to approach or move away from the interior of the first arc-shaped sheet, and the second sliding seat can drive the second electric heating tube thereon to approach or move away from the interior of the second arc-shaped sheet (see Figure 2 and Figure 3 ). In this embodiment, the two electric heating tubes and the two linear drives are controlled and operated by the PLC control center.

[0019] When the present embodiment is in the production state, the first electric heating tube and the second electric heating tube are always located in the first arc-shaped sheet and the second arc-shaped sheet under the action of the first linear drive and the second linear drive, and the two electric heating tubes are in the power-on heating state, and the heat generated by the two electric heating tubes can be directly transferred to the two arc-shaped sheets by thermal radiation, and the webbing flowing through the present embodiment slides over the outer arc surfaces of the first arc-shaped sheet and the second arc-shaped sheet in turn in a taut state, so that both sides of the webbing will be heated and shaped; when the present embodiment is urgently stopped or the production operation is stopped, the two electric heating tubes will be powered off, and at the same time, the first linear drive and the second linear drive will push the two heating seats to move in opposite directions, so that the first electric heating tube moves out of the first arc-shaped sheet, and the second electric heating tube moves out of the second arc-shaped sheet, so that the residual heat on the electric heating tubes will not continue to heat the arc-shaped sheet, and the arc-shaped sheet itself is a metal sheet, and its own heat will be quickly dissipated after losing the heating of the electric heating tube, so that the webbing is not easily burned.

[0020] The material of the positioning rod is heat-resistant plastic, and the outer surface of the two arc-shaped sheets is coated with a layer of Teflon. The tolerable temperature of the heat-resistant plastic and Teflon is higher than 250 degrees Celsius, and the set temperature of the two arc-shaped sheets in this embodiment is between 180 and 200 degrees Celsius. The positioning rod is made of heat-resistant plastic mainly because the specific heat capacity of plastic is low and the heat conduction efficiency is also poor. When the arc-shaped sheet loses the heating of the electric heating tube, the positioning rod will not continue to conduct heat to the arc-shaped sheet, and the heat of the arc-shaped sheet can be dissipated quickly. Teflon is a material that reduces the friction coefficient. Because there is sliding friction between the fabric and the arc-shaped sheet, this setting can reduce the friction between the fabric and the arc-shaped sheet.

[0021] See Figure 4 The feed guide roller is provided with four first annular grooves 410, and the discharge guide roller is provided with second annular grooves 420 corresponding to the first annular grooves one by one.

[0023] Reflective grooves are formed on the two heating seats, and the electric heating tubes are fixed in the reflective grooves. The opening direction of the reflective grooves is directly facing the arc-shaped sheet.

[0024] It is obvious to those skilled in the art that the utility model can be changed in many ways, and such changes are not considered to be out of the scope of the utility model. All such modifications obvious to those skilled in the art will be included in the scope of the claims.
