Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, in particular to a special-shaped winding core for conveyor belts. Background Art

[0002] Common conveyor belt winding methods include single-winding and double-winding. Single-winding conveyor belts have one end of the belt head inside the roll and the other end outside the roll. Double-winding conveyor belts have both ends of the belt head inside the roll. Usually, when making a conveyor belt joint, only one joint is vulcanized. The entire roll of conveyor belt is then rolled out before the other joint is vulcanized.

[0003] Conventional winding methods use a hollow cylindrical core. When both belt ends are placed outside the belt roll, this facilitates quick connection, saving belt changes and improving work efficiency. However, due to the thickness and hardness of conveyor belts, and the fact that single rolls are often 200 meters long, winding with a conventional core can severely impact product quality at the fold and result in poor appearance.

[0004] Therefore, how to avoid the problem that the folded portion is easily damaged when both belt heads are placed on the outside of the conveyor belt roll is a technical problem that those skilled in the art currently need to solve. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0028] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] In the description of the present invention, it should be understood that the terms "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0030] The utility model aims to provide a special-shaped winding core for a conveyor belt, which can avoid the problem that the folded portion is easily damaged when two belt heads are placed on the outside of the conveyor belt roll.

[0031] See also Figures 1 to 2 To achieve the above-mentioned purpose, the utility model provides a special-shaped winding core for a conveyor belt, comprising a first core body 100 and a second core body 200. The first core body 100 is provided with a first circumferential surface 110 for curling the conveyor belt, and the second core body 200 is provided with a second circumferential surface 210 for curling the conveyor belt. The first core body 100 and the second core body 200 are connected by a connecting piece 400 to form a cylindrical structure, and there is a first gap 300 between the first core body 100 and the second core body 200 for the conveyor belt to pass through.

[0032] It should be noted that the first circumferential surface 110 of the first core 100 and the second circumferential surface 210 of the second core 200 are both smooth surfaces. The smooth surfaces can avoid creases when the conveyor belt is rolled up. At the same time, considering that the position of the conveyor belt may need to be manually adjusted during the rolling of the conveyor belt, the first core 100 and the second core 200 are designed to be hollow structures. In order to reduce the cost of the first core 100 and the second core 200, it reduces the difficulty of manual adjustment of the conveyor belt position and improves the winding efficiency of the conveyor belt.

[0033] Among them, considering that the first circumferential surface 110 of the first core body 100 and the second circumferential surface 210 of the second core body 200 require a certain support strength during use to avoid the first circumferential surface 110 and the second circumferential surface 210 from becoming concave due to external force, it is possible to consider adding reinforcing rods inside the first core body 100 and the second core body 200 to maintain the stability of the first circumferential surface 110 and the second circumferential surface 210.

[0034] The conveyor belt is naturally folded in half so that the two ends of the conveyor belt are close to each other, and then the second core 200 is placed on the inner side of the folded part of the conveyor belt, and the first core 100 is placed on the outer side of the folded part of the conveyor belt and corresponds to the second core 200. The first core 100 and the second core 200 are connected by a connector 400 to form a cylindrical structure, and at the same time, the part of the conveyor belt that fits the second core 200 is located in the first gap 300 between the first core 100 and the second core 200. Then the cylindrical structure is rotated around its own axis to directionally curl the conveyor belt. By having the second core 200 located on the inner side of the folded part of the conveyor belt, the problem of the fold being easily damaged when both belt heads are placed on the outside of the conveyor belt roll can be avoided.

[0035] It can be understood that the first core 100 and the second core 200 are connected by a connecting piece 400 to form a cylindrical structure. The first core 100 and the second core 200 can adopt structures of the same size. Considering that the first core 100 and the second core 200 need to be driven by the rotating shaft of the reel machine to reel in the conveyor belt, the first core 100 and the second core 200 should be two structures of different sizes to ensure that the rotating shaft can pass through the larger one of the first core 100 and the second core 200 to ensure that the cylindrical structure formed by the subsequent rotating shaft drives the first core 100 and the second core 200 to rotate around its own axis.

[0036] Among them, taking the example of the first core 100 being smaller and the second core 200 being larger, the second core 200 should be placed on the inner side of the folded part of the conveyor belt. The larger second core 200 facilitates the initial fitting of the conveyor belt to the second circumferential surface 210 of the second core 200. Then, the second core 200 and the first core 100 located on the outer side of the folded part of the conveyor belt are connected through the connecting piece 400, and begin to wind toward the side of the first circumferential surface 110 of the first core 100.

[0037] In this embodiment, the first circumferential surface 110 includes a first plane 111 and a first arc surface 112 connected to each other, and the first plane 111 and the first arc surface 112 are smoothly connected. The second circumferential surface 210 includes a second plane 211 and a second arc surface 212 connected to each other, and the second plane 211 and the second arc surface 212 are smoothly connected.

[0038] It can be understood that the first plane 111 and the first curved surface 112 are tangent to each other at the end, so as to achieve a smooth connection between the first plane 111 and the first curved surface 112, and the second plane 211 and the second curved surface 212 are tangent to each other at the end, so as to achieve a smooth connection between the second plane 211 and the second curved surface 212. In addition, during the production process, a flat plate can be bent to a certain angle and then the two ends of the flat plate can be welded to form a welding line located in the middle of the first plane 111 or the second plane 211. The first plane 111 and the second plane 211 can then be smoothed by grinding to avoid wear on the conveyor belt.

[0039] The first plane 111 and the second plane 211 are located on the side where the first core 100 and the second core 200 face each other, and the first plane 111 and the second plane 211 are parallel to each other.

[0040] A first gap 300 of equal width is formed at each location by the parallel first plane 111 and the second plane 211. The first gap 300 is used for a single layer of the folded conveyor belt to pass through. The width of the first gap 300 can be adjusted according to the thickness of the conveyor belt to avoid the conveyor belt at the first gap 300 from sliding relative to the first core 100 and the second core 200, thereby affecting the subsequent winding process of the conveyor belt.

[0041] In this embodiment, the distance between the end of the first core 100 facing away from the second core 200 and the second plane 211 is smaller than the distance between the end of the second core 200 facing away from the first core 100 and the first plane 111 .

[0042] For example, the distance between one end of the second core 200 facing away from the first core 100 and the first plane 111 is 1.5-1.8 times the distance between one end of the first core 100 facing away from the second core 200 and the second plane 211 to ensure that the axis of the cylindrical structure formed by connecting the first core 100 and the second core 200 through the connecting member 400 is located within the second core 200.

[0043] In this embodiment, the first core body 100 also includes a first end face 120 located at both ends of the first circumferential surface 110 to seal the first circumferential surface 110, and the second core body 200 also includes a second end face 220 located at both ends of the second circumferential surface 210 to seal the second circumferential surface 210, and the connecting member 400 is connected to the corresponding first end face 120 and the second end face 220.

[0044] The conveyor belt needs to be partially passed through the first gap 300 between the first core 100 and the second core 200, and the first core 100 and the second core 200 need to be connected by a connector 400. The connector 400 is set to be connected to the corresponding first end face 120 and the second end face 220, which can ensure that the width of the conveyor belt that can penetrate into the first gap 300 on the axis of the cylindrical structure formed by the first core 100 and the second core 200 can be consistent with the length of the cylindrical structure on its own axis, and can adapt to the winding of conveyor belts of various widths.

[0045] The first end face 120 and the first circumferential surface 110 can be connected by welding, and the second end face 220 and the second circumferential surface 210 can also be connected by welding to ensure the stability of the first core 100 and the second core 200. The specific connection method between the first end face 120 and the first circumferential surface 110 and between the second end face 220 and the second circumferential surface 210 can also be adjusted according to actual conditions as long as the above-mentioned purpose can be achieved.

[0046] In this embodiment, a first through hole is provided on the first end surface 120, a second through hole is provided on the second end surface 220, and the connecting member 400 includes a plate body 410 and a fixing member 420, and the plate body 410 is provided with a third through hole corresponding to the first through hole, and a fourth through hole corresponding to the second through hole.

[0047] The fixing member 420 is passed through the third through hole and is detachably connected to the first through hole, and / or the fixing member 420 is passed through the fourth through hole and is detachably connected to the second through hole. The first core 100 and the second core 200 are connected through the plate body 410 and the fixing member 420. A limit head is provided at one end of the fixing member 420, and the limit head can abut against the side of the plate body 410 away from the first end face 120 or the second end face 220 to increase the stability of the connection.

[0048] Among them, the first through hole and the second through hole are both threaded holes, and the fixing member 420 is a screw adapted for the threaded hole, so that the fixing member 420 can be detachably connected to the first end face 120 and the second end face 220. Two first through holes are provided on the same first end face 120, and two second through holes are provided on the same second end face 220. The axes of the first through holes and the second through holes are parallel to each other. The number of the first through holes and the second through holes can also be set to multiple according to actual needs. At the same time, the above-mentioned plate body 410 with different distances between the third through hole and the fourth through hole can be prepared to realize the switching of multiple first gaps 300.

[0049] In addition, a square opening 221 is provided on the second end face 220, and the reinforcing plate is connected to the two openings on the two second end faces 220 to form a square through hole that passes through the second core body 200. Through the square through hole, it is convenient to manually connect the first core body 100 and the second core body 200 through the connecting piece 400 to form a cylindrical structure for transportation. At the same time, the subsequent conveyor belt can be wound around the cylindrical structure through the square through hole.

[0050] Place the head of the conveyor belt after natural folding (the middle position of the conveyor belt length) in the middle of the double-roller winding device, place the second core 200 on the inner side of the folded part of the conveyor belt with the second plane 211 of the inner second core 200 facing upwards, manually assist in winding the second core 200 and the conveyor belt tightly, place the first core 100 on the conveyor belt above the second core 200 with the first plane 111 of the first core 100 facing downwards, align the first core 100 and the second core 200 across the conveyor belt, and then connect and tighten them with the connector 400 for the subsequent winding process.

[0051] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0052] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
