[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-Figure 3This embodiment discloses a roll material feeding mechanism, including a belt material pressing and feeding unit 101 for installation on a device, and this embodiment also includes an auxiliary pressing unit 102, wherein the auxiliary pressing unit 102 is installed on a device frame 103 and is used to contact with the belt material pressing and feeding unit 101 and drive the belt material pressing and feeding unit 101 to be tightly attached to the roll material; the device is a non-woven fabric point-breaking folding machine or a non-woven fabric cutting machine;

[0032] The auxiliary pressing unit 102 includes a sliding seat 104, a push rod 105, a guide wheel assembly 106 and a counterweight 107. A sliding groove 108 is provided on the side of the frame 103. The sliding seat 104 is slidably arranged in the sliding groove 108. The push rod 105 is installed on the sliding seat 104. The guide wheel assembly 106 is arranged on the frame 103. The counterweight 107 is connected to the sliding seat 104 after passing through the guide wheel assembly 106 through a pull rope 113.

[0033] Under the action of the counterweight block 107 , the push rod 105 contacts the belt pressing and feeding unit 101 , and is used to drive the belt pressing and feeding unit 101 to press on the coil.

[0034] In actual use, the utility model promotes the belt pressing and feeding unit 101 to rotate through the arranged push rod 105, and under the gravity of the counterweight block 107, the pull rope 113 will pull the sliding seat 104 to move, thereby realizing the pushing of the push rod 105, and after the push rod 105 contacts with the belt pressing and feeding unit 101, the belt pressing and feeding unit 101 is driven to rotate, thereby making the belt pressing and feeding unit 101 in close contact with the coiled material, because the gravity of the counterweight block 107 is constant, the pressure exerted by the push rod 105 on the belt pressing and feeding unit 101 is also constant, thus avoiding the situation of being too tight or too loose, thereby realizing the stable feeding of the coiled material.

[0035] In order to facilitate those skilled in the art to further understand the present invention, the structure of the belt pressing and feeding unit 101 is further described.

[0036] In this embodiment, the belt pressing and feeding unit 101 includes a rotating shaft 109, a mounting frame 110, a driving pulley 111, a driven pulley 112, a motor and a telescopic rod 114. The rotating shaft 109 is rotatably mounted on the frame 103, the mounting frame 110 is fixedly mounted on the rotating shaft 109, the driving pulley 111 and the driven pulley 112 are rotatably mounted on the mounting frame 110, and the motor is fixedly connected to the driving pulley 111 after being installed on the mounting frame 110. The driving pulley 111 and the driven pulley 112 are connected by a belt 115, and the belt 115 is used to contact the coil, and the lower end of the mounting frame is in contact with the push rod 105; one end of the telescopic rod 114 is hinged on the frame 103, and the other end is hinged on the mounting frame 110, and the telescopic rod 114 is used to drive the mounting frame 110 to rotate.

[0037] The driving pulley 111 is driven to rotate by a motor, thereby driving the belt 115. After the belt 115 is pressed on the coil and starts to rotate, the coil can be driven.

[0038] In this embodiment, the telescopic rod 114 is in a stationary state during the loading process, that is, the telescopic rod 114 does not apply force to the mounting frame 110. At this time, the telescopic rod 114 extends or shortens following the rotation of the mounting frame 110. After the loading is completed, the telescopic rod 114 can drive the mounting frame 110 to rotate, thereby resetting the push rod 105 to replace a new coil.

[0041] As an option, in actual use, a slide groove may be provided on the frame 103, and the counterweight block 107 is slidably installed in the slide groove.

[0042] Furthermore, a rotating drum is rotatably mounted on the outer side of the push rod 105, and the rotating drum can convert the sliding friction with the mounting frame 110 into rolling friction, thereby reducing friction and wear.

[0043] Wherein, a wear-resistant layer is arranged on the rotating outer side.

[0044] In actual use, the guide wheel assembly 106 includes at least two guide wheels 116, which are rotatably mounted on the frame 103, wherein the tangent of one of the guide wheels 116 is flush with the sliding seat 104, so that the pull rope 113 is in a horizontal state.

[0045] Furthermore, the counterweight block 107 includes a frame and a plurality of counterweight units placed on the frame, and the frame is slidably mounted on the frame 103; in this way, the weight of the block can be increased or decreased as needed, so that the pressure of the push rod 105 on the mounting frame 110 can be adjusted, and then the belt 115 can adjust the pressure of the roll material. For different types of non-woven fabrics, the friction of the non-woven fabrics is different, and the pressure can be adjusted to meet the feeding requirements of the non-woven fabrics.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
