[0002] Currently, when materials are die-cut on a roller die-cutting machine to obtain sheets of the desired shape, excess waste is generated. In order to improve resource utilization, these die-cutting wastes need to be rolled up by a receiving device for centralized recycling and processing.

[0003] In the prior art, the receiving device on the die-cutting machine mainly reels the die-cutting waste through a reel. Although this method can achieve continuous and neat collection of waste, the reel needs to be disassembled and replaced each time the waste is reeled in sufficient quantity. The unloading on the current receiving device requires the entire reel to be disassembled and then replaced with a new reel for subsequent receiving work. The disassembly and assembly process is cumbersome, time-consuming and labor-intensive, which reduces work efficiency and increases workload, making it difficult to meet usage requirements. For this reason, a die-cutting machine receiving device is proposed that facilitates unloading of waste after reeling. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-Figure 3 The die-cutting machine receiving device shown includes an end cover plate 100, a winding shaft 200 is provided in the middle of one side of the end cover plate 100, and the winding shaft 200 includes a frustum column 202, a plurality of support petals 201 and a clamping spring 203. The frustum column 202 is in the shape of a frustum column, and the diameter of the frustum column 202 gradually decreases in the direction close to the end cover plate 100. The plurality of support petals 201 are wrapped around the outer wall of the frustum column 202 in an annular array. The side of the support petal 201 close to the frustum column 202 has an arc conical surface adapted to the outer wall of the frustum column 202. Positioning grooves 204 are provided at both end positions of the outer wall of the support petal 201. There are two clamping springs 203 and they are respectively sleeved in the positioning grooves 204 at both end positions of the outer wall of the plurality of support petals 201. The frustum column 202 is wrapped by the plurality of support petals 201, and The side of the support flap 201 facing the conical column 202 has a taper that is adapted to the outer wall of the conical column 202. The tightening force provided by the clamping spring 203 to the multiple support flaps 201 can enable the conical column 202 to drive the multiple support flaps 201 to expand or contract through axial transverse movement, thereby changing the diameter of the reel 200. In this way, the reel 200 is kept in an open state with a larger diameter when reeling in the waste. After the waste is reeled in, it is only necessary to reduce the diameter of the reel 200 by transverse movement of the conical column 202, so that it can be separated from the reeled waste. In this way, the reeled waste can be directly pulled out from the reel 200 to complete the unloading. For reuse, it is only necessary to restore the reel 200 to its original diameter. The operation is simple and convenient, and the efficiency is high.

[0023] Furthermore, a drive shaft 205 is fixedly connected to the middle of one side of the end cover 100 close to the winding shaft 200. The drive shaft 205 is a polygonal column. A through hole matching the drive shaft 205 is opened in the middle of the cone column 202. The setting of the drive shaft 205 allows the cone column 202 and the end cover 100 to maintain radial relative fixation. In this way, the winding shaft 200 can rotate with the rotation of the end cover 100, and at the same time, the cone column 202 can move axially along the drive shaft 205 to adjust the diameter of the winding shaft 200. An elastic compression spring 206 is fixedly connected between the cone column 202 and the end cover 100. The outer wall of the drive shaft 205 is located on the cone. A limiting mechanism is provided on the side of the column 202 away from the end cover plate 100, and the elastic compression spring 206 can provide a thrust for the circular column 202 to move in the direction away from the end cover plate 100, and cooperate with the limiting mechanism to limit the position of the circular column 202 on the drive shaft 205. During specific operation, it is only necessary to unlock the limiting mechanism to allow the elastic compression spring 206 to drive the circular column 202 to move outward, so that the diameter of the winding shaft 200 is automatically reduced, thereby improving the convenience of operation. When resetting, it is only necessary to squeeze the circular column 202 to move it into position in the direction of the end cover plate 100, and the locking limiting mechanism can complete the limitation of the position of the circular column 202, thereby ensuring the stability of the winding shaft 200 during use.

[0024] Among them, the limiting mechanism includes a limiting sleeve 207, which is slidably sleeved on the outer wall of the drive shaft 205, and the side wall of the limiting sleeve 207 is threadedly connected with a positioning screw 208. The outer wall of the drive shaft 205 is provided with a limiting through hole matching the positioning screw 208. After the cone column 202 is in place, it is only necessary to insert the positioning screw 208 and turn the knob to fix the positioning screw 208 to the limiting sleeve 207, so that the limiting sleeve 207 has a blocking effect on the cone column 202, so that the reset moves in the direction away from the end cover plate 100, wherein the external thread of the positioning screw 208 can be set at the end of its outer wall near the drive head position, so that the positioning screw 208 can be directly inserted into the limiting through hole and then threadedly pressed with the limiting sleeve 207, which makes operation more convenient.

[0025] Among them, a plurality of guide slots 101 are opened on the side of the end cover plate 100 close to the winding shaft 200, and a guide slider 102 is slidably connected in each of the plurality of guide slots 101. The side of the guide slider 102 close to the support flap 201 is fixedly connected to the end face of the support flap 201 at the corresponding position. The guide slots 101 on the end cover plate 100 cooperate with the guide slider 102 to limit the position between the support flap 201 and the end cover plate 100, so that the support flap 201 can only expand or retract along the guide slots 101 to ensure the stability of the movement of the support flap 201.

[0026] In addition, the side of the end cover plate 100 facing away from the winding shaft 200 is rotatably connected to the support seat 300, and a winding motor 301 is fixedly installed on the top of the support seat 300 facing away from the end cover plate 100. The winding motor 301 is used to drive the end cover plate 100 to rotate. By driving the end cover plate 100 to rotate by the winding motor 301, the winding shaft 200 can be driven to rotate to realize the collection of waste materials. The support seat 300 can keep the winding shaft 200 and the end cover plate 100 positioned at a high position to meet usage requirements.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
