[0001] The present application relates to the technical field of drafting machines, and in particular to a support frame for a drafting machine. Background Art

[0002] For example, a Chinese utility model patent with authorization announcement number CN201581185U discloses a drafting machine, including: a drafting machine roller group composed of multiple drafting machine rollers and a pressure roller component, the main shaft of the pressure roller component is hinged on the drafting machine mainframe and contacts the drafting machine roller, and the axis of the pressure roller component is parallel to the axis of the drafting machine roller, and a bracket is welded on the main shaft of the pressure roller to adjust the pressure between the pressure roller and the drafting machine roller by a weight placed on the bracket. It can be seen from the above technical scheme that the utility model is provided with a pressure roller on the drafting machine roller of the drafting machine, and when the spinning is pulled out in the drafting machine, the spinning is stretched by the friction between the spinning and the drafting machine roller. Since the pressure roller component is hinged on the drafting machine roller and there is a bracket on the pressure roller component, a heavy object can be placed on the bracket according to actual needs to increase the pressure between the pressure roller component and the drafting machine roller. When the pressure increases, the friction between the spinning and the drafting machine roller also increases accordingly, effectively preventing the drafting machine roller from slipping and improving the drafting effect of spinning.

[0003] However, since the drafting machine roller is a single cantilever structure installed on one side, there is a certain amount of jumping and instability. Utility Model Content

The two lower drafting machine rollers 1122 are arranged at equal intervals along the horizontal direction. The three upper drafting machine rollers 1121 and the two lower drafting machine rollers 1122 are arranged in a staggered manner along the horizontal direction. The support wall panel 120 and the support plate 111 respectively give support forces to both ends of the drafting machine roller 112, so that the support structure is relatively stable, reducing the probability of the drafting machine roller 112 jumping and improving the working stability of the drafting machine roller 112.

[0031] Specifically, in this embodiment, the support frame platform 110 includes a horizontally arranged support flat plate 1101, two transverse vertical plates 1102, and two longitudinal vertical plates 1103. The two transverse vertical plates 1102 and the two longitudinal vertical plates 1103 are both located below the support flat plate 1101. The transverse vertical plates 1102 and the longitudinal vertical plates 1103 are staggered and joined end to end to form a rectangular structure with a projection plane coinciding with the support flat plate 1101. Two I-shaped openings 114 penetrate through the transverse vertical plates 1102, and the two I-shaped openings 114 are spaced along the length direction of the transverse vertical plates 1102. One I-shaped opening 114 is provided on the longitudinal vertical plates 1103.

[0032] Furthermore, four support feet 115 are arranged below the support frame platform 110. The four support feet 115 are distributed in a rectangular shape below the support frame platform 110. In this embodiment, the support feet 115 are arranged at the connection of each transverse vertical plate 1102 and the longitudinal vertical plate 1103. The support feet 115 include support columns 1151 and anti-slip round pads 1152. The support columns 1151 are vertically arranged. One end of the support column 1151 is connected to the bottom of the support frame platform 110, and the other end of the support column 1151 is coaxially connected to the anti-slip round pad 1152.

[0033] In order to enable the support wall panel 120 to be adapted to more drafting machines, an installation plate 121 is provided at the bottom of the side wall of the support wall panel 120 away from the support plate 111. In this embodiment, the installation plate 121 is perpendicular to the support wall panel 120. A plurality of installation bolts 122 penetrate through the installation plate 121. The plurality of installation bolts 122 are equidistantly spaced along the length direction of the installation plate 121. The installation bolts 122 sequentially penetrate through the installation plate 121 and the support frame platform 110.

[0034] Reference Figure 1 、 Figure 2 and, a plurality of drafting machine roller covers 130 are provided on the support wall panel 120. In this embodiment, a total of five drafting machine roller covers 130 are provided. The five drafting machine roller covers 130 correspond to the five drafting machine rollers 112 one by one. A plurality of shaft cover bolts 131 penetrate through the drafting machine roller covers 130. The plurality of shaft cover bolts 131 are equally angularly spaced along the circumferential direction of the drafting machine roller covers 130. The shaft cover bolts 131 sequentially penetrate through the drafting machine roller covers 130 and the support wall panel 120. One end of the drafting machine roller cover 130 close to the drafting machine roller 112 is embedded with a bearing 132. One end of the bearing 132 away from the drafting machine roller cover 130 is connected to the drafting machine roller 112 to realize the circumferential rotation and axial fixation connection relationship between the drafting machine roller 112 and the support wall panel 120.

[0035] Furthermore, reference Figure 1, there are multiple observation windows 123 penetrating through the support wall panel 120. In this embodiment, there are three observation windows 123 in total. The observation windows 123 are vertically located between the upper drafting machine roller 1121 and the lower drafting machine roller 1122. The three observation windows 123 penetrate through the support wall panel 120 at equal horizontal intervals. The opening of the observation windows 123 facilitates the operator to observe the working conditions inside the equipment in the aisle.

[0036] Reference Figure 1 、 Figure 3 , in order to adjust the pressure applied to the silk thread, a sliding mounting frame 141 and a pressure roller 140 are arranged on the support frame platform 110. In this embodiment, the sliding mounting frame 141 includes a horizontally arranged mounting cross plate 1411 and two vertically arranged mounting vertical plates 1412. The two mounting vertical plates 1412 are respectively connected to both ends of the mounting cross plate 1411. A middle shaft 142 is coaxially penetrated through the pressure roller 140. Both ends of the middle shaft 142 are respectively connected to the opposite side walls of the two mounting vertical plates 1412. The pressure roller 140 is arranged at one end of the support frame platform 110 close to the entry of the silk thread. The pressure roller 140 is vertically located above the upper drafting machine roller 1121. Driving cylinders 143 are arranged on the opposite side walls of the support plate 111 and the support wall panel 120. The piston rod of the driving cylinder 143 is connected to the lower surface of the mounting cross plate 1411. The two driving cylinders 143 are vertically symmetrically arranged with respect to the sliding mounting frame 141. During the operation of the driving cylinder 143, the piston rod of the driving cylinder 143 drives the sliding mounting frame 141 to reciprocate and be positionable in the vertical direction, and then drives the pressure roller 140 to reciprocate in the vertical direction, so as to adjust the pressure applied to the silk thread.

[0037] The implementation principle of a drafting machine support frame in an embodiment of the present application is as follows: The support wall panel 120 and the support plate 111 respectively give support forces to both ends of the drafting machine roller 112, making the support structure relatively stable, reducing the probability of the drafting machine roller 112 jumping, and improving the working stability of the drafting machine roller 112.
