Description

Technical Field

[0001] The present invention relates to the technical field of coiled material slitting, and more particularly to a separator for double-opening adhesive drums and discs. Background Art

[0002] Typically, in the paper, film, and steel coil slitting industry, the material is first rolled into a long tube and then slit according to the corresponding size to separate the long tube into several small sections. However, during the slitting process, for example, when slitting paper rolls, the cut paper coils often stick together and cannot be separated. In actual production, these stuck coils are directly scrapped, reducing production yields and wasting resources.

[0003] Prior art (CN103803318A) discloses a method and mechanism for separating thin-sheet media, but this solution is not suitable for separating adhered hollow cylindrical discs (referred to as discs). To prevent adhesion when separating layered stacks, prior art (CN101830356A) discloses a contact-type separation device that uses friction to deform the objects, separating adjacent objects. However, this solution requires the stacked layers to be deformable and is not suitable for separating adhered hollow cylindrical discs. Summary of the Invention

[0004] The object of the present invention is to provide a separator for double-opening sticky discs to solve the problem that sticky discs stick together after being cut and are difficult to separate.

[0005] In order to solve the above technical problems, the specific technical solutions adopted by the present invention are as follows:

[0006] A separator for a double-opening adhesion drum disc, comprising a separation mechanism and a driving device that provides rotational power for the separation mechanism; the separation mechanism comprises a separation disc, a rotating shaft and a fixed seat with a matching portion connected in sequence; the fixed seat is provided with a rotating shaft mounting hole that matches the rotating shaft; the rotating shaft mounting hole and the axis of the fixed seat are parallel to each other and staggered; the rotating shaft and the axis of the separation disc are parallel to each other and staggered; the boundary formed by the matching portion and the outermost edge of the separation disc is substantially consistent or identical in shape and size, and the matching portion coincides with the projection of the separation disc at at least a certain angle of rotation of the rotating shaft.

[0007] During use, the core of a cylindrical disc (e.g., a paper roll) is inserted into the overlapping mating portion and separation disc. The drive mechanism is then activated. Because the shaft mounting hole and the axis of the mounting base are parallel and offset, when the shaft rotates the separation disc to a certain angle, the separation disc undergoes eccentric motion relative to the mounting base, separating adjacent paper rolls that have adhered to each other. Once the paper rolls are separated, the drive mechanism is activated again, driving the shaft to rotate and return the separation disc to its aligned position, ready for the next use.

[0008] In the present invention, the axial length of the engaging portion does not exceed the height of the paper coil to be separated. This is to ensure that the engaging portion does not hinder the movement of the upper paper coil in the adjacent paper coil when the separation disc and the engaging portion are misaligned. However, the axial length of the engaging portion cannot be too short. If the engaging portion is too short, it will not provide sufficient support for the lower paper coil and will not achieve the purpose of separation. Therefore, the appropriate axial length of the engaging portion should be equal to or less than the height of the cylindrical disc.

[0009] In the present invention, the boundary formed by the mating portion and the outermost edge of the separation disc is generally consistent in shape and size. "Generally consistent" refers to the fact that due to manufacturing tolerances, there may be some difference between the boundary formed by the mating portion and the outermost edge of the separation disc. The consistency between the boundary formed by the mating portion and the outermost edge of the separation disc is required to ensure smooth insertion of the paper tray.

[0010] The present invention utilizes the principle of eccentric dislocation to separate stuck cylindrical discs with open ends. This effectively resolves the problem of sticking discs of paper, film, steel, and other materials in actual production, reducing scrap rates. Furthermore, the present invention boasts a simple structure and low cost, making it ideally suited for the current slitting industry and promising future applications.

[0011] As a further technical solution of the present invention, the matching portion is used to be inserted into the disc to be separated, and the boundary formed by the outermost edge can form an annular gap with a width of 1 to 2 mm with the hollow part of the disc to be separated.

[0012] As a further technical solution of the present invention, the matching portion is cylindrical.

[0013] Because most of the products in the current slitting industry are cylindrical, on the one hand, it is to suit the cylindrical products to be separated, and on the other hand, the transition between the cylindrical mating part and the contact point between the separation disc and the product to be separated is smooth and will not damage the product. Therefore, the mating part is set to be cylindrical, and the separation disc that matches it is also cylindrical.

[0014] As a further technical solution of the present invention, the distance between the axis of the rotating shaft mounting hole and the axis of the fixing seat is 10 mm. Such a structure can better separate the drum and the disc.

[0015] As a further technical solution of the present invention, the rotating shaft can rotate within a range of 0 to 90 degrees. The rotating angle of the rotating shaft is sufficient to separate the sticky drum and disc. Excessive rotation angle is unnecessary, and rotation beyond the critical angle that can separate the drum and disc is a waste of energy.

[0016] As a further technical solution of the present invention, a bearing is provided in the shaft mounting hole; and retaining springs are provided at the upper and lower ends of the bearing. The bearing and retaining springs enhance the stability of the device and prevent the shaft from moving out of alignment.

[0017] As a further technical solution of the present invention, the shaft head at the lower end of the rotating shaft is a rectangular shaft head. Such a structure has a firm fit, stable output power, and is not prone to slipping.

[0018] As a further technical solution of the present invention, the fixing seat further includes a fixing portion; the separator further includes a mounting plate; and the fixing portion is bolted to the mounting plate.

[0019] As a further technical solution of the present invention, the separator further comprises a mounting frame connected to the mounting plate; the mounting frame is provided with universal wheels. Such a structure facilitates movement of the position.

[0020] As a further technical solution of the present invention, a long hole flange is provided between the fixing seat and the mounting plate. Such a structure facilitates adjustment and ensures that the fixing seat and the rotating shaft are in a concentric position when the separator is started.

[0021] As a further technical solution of the present invention, the driving device is a rotary cylinder; the air ports at both ends of the rotary cylinder are respectively connected to one-way throttle valves, the one-way throttle valves are connected to a manual reversing valve, and the manual reversing valves are connected to a pneumatic control element located on the mounting bracket.

[0022] A one-way throttle valve connects to each end of the rotary cylinder, adjusting the airflow to control rotational speed. The other end of the one-way throttle valve is connected to the outlet of a manual reversing valve. The inlet of the manual reversing valve is connected to the outlet of the pneumatic three-component, and the inlet of the pneumatic three-component is connected to the main compressed air source, forming a complete air control circuit.

[0023] During operation, first ensure that the mounting base and the separation disc are concentric. Then, insert the disc to be separated, such as a paper roll core, into the mounting base. Push the manual reversing valve handle downward, and the rotating cylinder will rotate, driving the rotating shaft to rotate, causing the center of the separation disc to shift with the center of the mounting base, thereby shifting and separating the two bonded paper rolls. Next, push the manual reversing valve handle upward, and the rotating cylinder will drive the rotating shaft to rotate, returning the separation disc to its starting position. The separated paper rolls can be removed manually.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention utilizes the separation mechanism described above and utilizes the principle of eccentric dislocation to separate stuck drums and reels, effectively resolving the problem of sticking drums and reels of paper, film, steel, and other materials in actual production, thereby reducing the scrap rate. The present invention is suitable for the current slitting industry and has great application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] A further technical solution of this embodiment 1 is that the fitting portion 131 is used to be inserted into the disc to be separated, and the boundary formed by the outermost edge can form a circumferential gap with a width of 1 to 2 mm with the hollow portion of the disc to be separated. In this embodiment 1, the fitting portion 131 is cylindrical. The axis spacing distance between the rotating shaft mounting hole 132 and the fixing seat 13 is 10 mm. A bearing 1321 is provided in the rotating shaft mounting hole 132; the upper and lower ends of the bearing 1321 are respectively provided with a retaining spring 1322. The rotating shaft 12 can rotate within a range of 0 to 90 degrees. In order to better cooperate with the rotation, the lower end shaft head of the rotating shaft 12 is a rectangular shaft head.
