Description

Technical Field

[0001] This utility model relates to the field of magnetic separator manufacturing technology, specifically a cutting device for the magnetic separator's outer layer. Background Technology

[0002] The magnetic assembly of a magnetic separator is made up of many magnetic blocks assembled by adhesive bonding. However, since magnetic separators are generally used in mines or in harsh environments, a galvanized steel coil is installed around the magnetic blocks to prevent them from falling off and to add a second layer of protection.

[0003] Existing roll material processing equipment requires manual winding, flattening, and cutting. Magnetic separators attach magnetic sheets to the magnet surface, but manual cutting results in low precision and uneven cross-sections, preventing a tight fit between the sheet and the magnet. Excessive gaps can cause friction between the sheet and the separator drum, leading to rework during installation.

[0004] Existing large-scale sheet metal cutting equipment generally requires professional personnel to operate. Professional cutting equipment is relatively expensive and not suitable for occasions with low usage frequency. Manual cutting, on the other hand, suffers from low precision due to various reasons, making it impossible to guarantee the conditions of use, and has an extremely high scrap rate.

[0005] The traditional method usually involves manual cutting. A section is cut first to serve as a template, and then the pieces are cut according to this template, resulting in inconsistent lengths of the boards.

[0006] Reference CN202421066278.4 A sheet metal cutting machine for processing sheet metal; by setting an adjustment mechanism, the device can adjust the cutting of sheet metal of different sizes according to different needs.

[0007] However, the aforementioned references have the problem of non-adjustable thickness. Different magnetic separators have different requirements for the thickness of the magnetic coating, which is related to changes in magnetic field strength. Therefore, raw materials of different thicknesses need to be cut stably.

[0008] To address this issue, we provide a cutting device for the magnetic separator's magnetic coating to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] Example 1

[0051] Please see Figure 1-6 This utility model provides a technical solution: a cutting device for wrapping magnets in a magnetic separator, comprising:

[0052] like Figure 1 The work platform 1 shown has a support frame assembly 2, on which the raw material roll 3 is mounted; combined with Figure 3As shown, the work platform is a bottom guide rail frame, mainly serving to support the various components. The raw material in the raw material roll is, in this application, a magnetic sheath, and its raw material is similar to steel coils, arranged in a wound configuration. During use, a pre-installed central shaft facilitates hoisting and relocation.

[0053] The conveying assembly 4 is used to push the raw material wound on the raw material roll 3; it includes a lower roller assembly 5 and an upper roller assembly 6. The lower roller assembly 5 is installed on the working platform 1, and the upper roller assembly 6 can elastically move up and down relative to the lower roller assembly 5 in the vertical direction. In this application, the upper roller assembly is configured to be able to elastically change in the vertical direction relative to the lower roller assembly, thereby realizing the function of conveying raw materials of different thicknesses.

[0054] Cutting component 7 is used to cut the raw material pushed by conveying component 4.

[0055] refer to Figure 4 and Figure 5 The lower roller assembly 5 includes a lower roller 51, and lower bearing supports 52 are installed at both ends of the lower roller 51. The lower bearing supports 52 are detachably connected to the working platform 1.

[0056] The upper roller assembly 6 includes an upper roller 61, and upper bearing supports 62 are installed at both ends of the upper roller 61.

[0057] The axis of the upper roller 61 and the axis of the lower roller 51 are coplanar and parallel, and are vertically distributed; this means that the ends of the upper roller and the lower roller share the same vertical plane, ensuring that the raw material is pushed forward vertically.

[0058] Position frames 41 are installed on both sides of the working platform 1. An elastic element is installed between the position frame 41 and the upper bearing support 62. The elastic element keeps the upper roller shaft 61 moving vertically relative to the lower roller shaft 51.

[0059] like Figure 4 As shown, the position frame 41 is C-shaped and downwardly positioned; the elastic element includes a vertical bolt 42, which is mounted on the position frame 41, and the bolt body of the vertical bolt 42 passes through the upper bearing support 62 and is positioned by a nut.

[0060] A spring 43 is fitted onto the vertical bolt 42. The top of the spring 43 is fixedly connected to the inner wall of the position frame 41, and the bottom is fixedly connected to the upper bearing support 62. The spring configuration allows the conveying assembly to accommodate raw materials of different thicknesses.

[0061] like Figure 5As shown, the upper roller 61 is wrapped with an upper rubber sleeve 63, and the lower roller 51 is wrapped with a lower rubber sleeve 53. The axial lengths of the upper and lower rubber sleeves 63 and 53 are not less than the width of the raw material in the same direction, ensuring continuous transmission. The rubber sleeves press against the upper and lower sides of the raw material to push it forward. The rubber sleeves prevent damage to the roller surface caused by direct collision.

[0062] In its natural state, spring 43 causes the upper rubber sleeve 63 of the upper roller 61 to move and abut against the lower rubber sleeve 53 of the lower roller 51; the natural state refers to the state where no material is introduced, and at this time, under the action of the spring, reference... Figure 4 As shown, pushing the upper bearing support downward causes the two sets of rubber sleeves to be squeezed.

[0063] A rotating handle 64 is coaxially mounted on the external side of the upper roller 61, allowing manual rotation of the upper roller to facilitate initial insertion of raw materials into both the upper and lower rollers. The rollers have a certain length range to accommodate rolls of material of varying widths.

[0064] A central shaft 31 is provided in the middle of the raw material roll 3, and a rotating shaft 32 is installed inside the central shaft 31;

[0065] Two sets of the bearing frame group 2 are provided and located on both sides of the raw material roll 3;

[0066] refer to Figure 3 As shown, the support frame assembly 2 includes a side frame 21, with two sets of side frames located on both sides of the work platform. An open bearing seat 22 is installed on the top of the side frame 21, secured to the top of the side frame with bolts. The top of the open bearing seat has an upward-facing mounting opening for accommodating the load-bearing central shaft. The open bearing seat 22 supports the bottom ends of the rotating shaft 32. The side frame 21 is fixed to the work platform 1, and a bent support frame 23 is fixedly installed on the outer side of the side frame 21. The bent support frame can be formed by welding angle plates, and the bent support frame 23 is angled to fix both the work platform 1 and the side frame 21. When the work platform is placed on the ground, the bent support frame 23 increases the contact area with the ground, preventing the side frame from tilting and providing protection.

[0067] refer to Figure 3 and Figure 6 As shown, the cutting assembly 7 includes a cutting frame 71, which is fixedly installed on the work platform 1; a push rod 72 is installed inside the cutting frame 71, the push rod 72 is vertically distributed and its output end is downward and fixedly connected to a connecting block 73;

[0068] A cutter 74 is fixedly installed at the bottom of the connecting block 73, and the bottom of the cutter is sharpened; a vertical groove 75 is provided on the side of the cutting frame 71 facing away from the bearing frame assembly 2, such as... Figure 6 As shown, sliders 76 are installed at both ends of the cutter 74, and the sliders 76 are adapted to the vertical groove 75; the inner bottom side of the cutting frame 71 is used to pass raw materials, and the bottom side of the cutter 74 is used to cut the raw materials to form finished boards.

[0069] The work platform 1 also includes a finished product rack 8, on which a measuring ruler 81 is marked. The length direction of the measuring ruler 81 is the same as the direction of material movement. It is used to measure the length of the material before cutting, and to cut the material after the length reaches the required standard.

[0070] The bottom of the cutting frame 71 is provided with a long iron block 77.

[0071] The cutting frame 71 is located between the position frame 41 and the finished product frame 8. A gap is provided between the cutting frame 71 and the finished product frame 8 to allow enough space for the cutter 74 to descend.

[0072] Instructions for use: First, insert the raw material roll 3 onto the central shaft 31, hoist it onto the two sets of open bearing seats, and install it. Turn the handle 64 to drive the upper roller shaft to rotate. The upper rubber sleeve attached to the surface of the upper roller shaft generates a frictional force with the raw material, causing the lower rubber sleeve and the lower roller shaft to move together, thus moving the raw material forward. A spring is installed above the upper bearing support, and the spring moves along the vertical bolt, ensuring a large frictional force between the upper and lower rubber sleeves. Observe the measuring scale. When the raw material extends the required distance, the push rod drives the cutter to move, generating a shearing force between it and the iron block, thus cutting the raw material to the required length. For the initial raw material conveying, manual traction is required to pass it between the upper and lower roller shafts. Subsequent continuous conveying can be achieved; then, quantitative cutting of the raw material is performed.

[0073] The cutting device of this invention is compact, low in manufacturing cost, requires no professional operation, is easy to install, and can also serve as a storage location for rolled materials when not in use. When cutting is required, the raw material roll is first hoisted onto the open bearing seat and supported by the lateral frame to ensure the height meets the load-bearing standard. Then, the elastic element within the conveying assembly ensures that rolls of different thicknesses and widths can be conveyed. The width is less than the length of the roll, and the thickness is less than the elastic limit of the elastic element within the conveying assembly.

[0074] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
