It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To address the technical problem of material rolls easily shifting during feeding, this invention provides an automatic deviation correction feeding device that can automatically correct deviations when the material rolls shift, thereby improving feeding quality.

[0025] It should be noted that the automatic deviation correction feeding device described in this utility model is used for, but not limited to, foamed film, etc. For ease of explanation, this utility model only uses the automatic deviation correction feeding device for foamed film feeding as an example. The principle of the automatic deviation correction feeding device for other lightweight rolls is essentially the same as that for foamed film feeding, and will not be described in detail here.

[0026] Please see Figure 1 and Figure 2 , Figure 1 This is a front view of the automatic deviation correction feeding device provided in this embodiment of the utility model; Figure 2 This is a top view of the automatic alignment and feeding device provided in this embodiment of the utility model. The automatic alignment and feeding device includes a frame 1, a detection mechanism 2, and an adjustment mechanism 3.

[0027] The frame 1 includes a main frame 11, a raw material rack 12, and a mounting frame 13. The raw material rack 12 is slidably connected to the main frame 11 along a first direction A. The raw material rack 12 is used to place the raw material roll 900 and to ensure that the axis of the raw material roll 900 is along the first direction A. It is easy to understand that the first direction A is the width direction of the raw material. The mounting frame 13 is fixedly connected to the main frame 11.

[0028] The detection mechanism 2 and the mounting frame 13 are fixedly and slidably connected along the first direction A. The detection device 2 can detect whether the raw material supplied by the raw material roll 900 is misaligned. When misalignment occurs, a signal is sent to control the adjustment mechanism 3 to make adjustment.

[0029] The adjusting mechanism 3 is connected to the raw material rack 12, and the detection mechanism 2 is controlled by the adjusting mechanism 3. Under the control of the detection mechanism 2, the adjusting mechanism 3 can drive the raw material rack 12 to move along the first direction A. It moves in the opposite direction according to the offset, thus offsetting the offset and improving the stability of the raw material roll 900 feeding, thereby improving the quality of the finished product.

[0030] In some embodiments, the main frame 11 includes two main boards 111 and a slide rail 112. The slide rail 112 is arranged along a first direction A and its two ends are fixedly connected to the two main boards 111 respectively.

[0031] Please see Figure 3 In some embodiments, the material rack 12 includes a base plate 121 and a plurality of balls 122. A groove is formed on the lower surface of the base plate 121, and the balls 122 are disposed on the inner side surface and / or the inner top surface of the groove. The slide rail 112 abuts against the balls 122. The balls 122 can reduce frictional resistance and achieve higher precision control.

[0032] In some embodiments, the raw material rack 12 further includes two sub-plates 123 and a raw material roller 124. The two sub-plates 123 are fixedly connected to the base plate 121, and the raw material roller 124 is arranged along a first direction A and detachably connected to the sub-plates 123. The raw material roller 124 is used to hold raw material rolls. The raw material roll 900 can be threaded onto the raw material roller 124 and rotate freely relative to the raw material roller 124; or the raw material roll 900 rotates synchronously with the raw material roller 124, and the raw material roller 124 rotates freely relative to the sub-plates 123.

[0033] In a preferred embodiment, one end of the raw material roller 124 can be directly connected to a motor or indirectly connected to a motor through a transmission mechanism. The motor drives the raw material roller 124 to rotate, which plays an auxiliary role in feeding materials.

[0034] In some embodiments, the mounting bracket 13 is a rod-shaped structure arranged along the first direction A and fixedly connected to two main boards 111. The detection mechanism 2 can adjust and fix its position on the mounting bracket 13 to accommodate raw material rolls 900 of different widths.

[0035] In some embodiments, the frame 1 further includes a guide roller 14, which is arranged along a first direction A and has its two ends rotatably connected to two main boards 111. When the raw material is fed, it passes around the guide roller 14, and the guide roller plays the role of tensioning the raw material. The detection mechanism 2 is arranged toward the guide roller 14, specifically aligned with the side edge of the raw material, and determines whether there is a deviation by detecting the position of the edge.

[0036] Please see Figure 4In some embodiments, the detection mechanism 2 includes a detector 21 and a connector 22. The detector 21 is fixedly connected to the connector 22, and the connector 22 is movably and fixedly connected to the mounting bracket 13. The detector 21 is controlled to be connected to the adjustment mechanism 3 to control the adjustment mechanism 3 to drive the raw material rack 12 to move along the first direction A.

[0037] The detector 21 can be a commonly used sensor such as a photoelectric sensor or an industrial camera, as long as it can perform the detection function.

[0038] In some embodiments, the connector 22 includes two spring contacts 221 and a fixing member 222. One end of the two spring contacts 221 is fixedly connected to the detector 21, and the other end of the two spring contacts 221 is detachably connected via the fixing member 222. The fixing member 222 can be a bolt and nut mechanism or a pin mechanism, etc. The two spring contacts 221 are clamped to the mounting bracket 13 by the fixing member 222, thus achieving fixation. In a preferred embodiment, the mounting bracket 13 is provided with two detection mechanisms 2, which are used to detect the two sides of the raw material, respectively.

[0039] Please see again Figure 2 and Figure 3 In some embodiments, the adjustment mechanism 3 includes an adjustment motor 31, a lead screw 32, and a slider 33. The axis of the lead screw 32 is along a first direction A. The adjustment motor 31 is fixedly connected to the lead screw 32 to drive the lead screw 32 to rotate around its own axis. The slider 33 is fixedly connected to the raw material rack 12, specifically located on the lower surface of the base plate 121. The slider 33 has a threaded hole, through which the lead screw 32 passes and engages with the internal thread of the threaded hole. By driving the lead screw 32 to rotate in different directions, the adjustment motor 31 can control the left and right movement of the raw material rack 12, thereby achieving the correction function. The detection mechanism 2 is specifically a detector 21 that is controlled and connected to the adjustment motor 31. Under the control of the detector 21, the adjustment motor 31 can drive the lead screw 32 to rotate clockwise or counterclockwise, thereby driving the raw material rack 12 to move and offset the offset.
