Description

[0002] A sponge flat cutter is a mechanical device specifically designed to cut large pieces of sponge horizontally into thin sheets of the required thickness.

[0003] Most existing sponge flat cutting machines use pressure plates or rollers to fix the sponge, reducing the vertical jumping phenomenon that easily occurs when lightweight sponges are conveyed or cut at high speeds. However, the single pressure plate or roller limits the sponge, and displacement can easily occur due to conveying inertia or lateral cutting force during the sponge conveying and cutting process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A lightweight sponge flat cutting mechanism includes a flat cutting machine body 1, which includes a conveying unit 11. A cutting unit 12 is provided on one side of the conveying unit 11, and an auxiliary limiting component 2 is provided on the conveying unit 11 and on the side of the cutting unit 12. The auxiliary limiting component 2 includes a mounting frame 21. A movable frame 23 is slidably provided inside the mounting frame 21 and above the conveying unit 11. The movable frame 23 is driven by a hydraulic telescopic rod assembly 24, and a pressure roller assembly 27 is provided below the movable frame 23.

[0025] It is worth noting that the specific structure, connection method and working principle of the flat cutting machine body 1, the conveying unit 11 and the cutting unit 12 are all existing technologies that are currently publicly available on the market, so they will not be elaborated further.

[0026] The conveying unit 11 is provided with guide components 22 on both sides. The guide components 22 include a fixed seat, and guide rods are fixedly installed on both sides of the fixed seat. The other side of the guide rod is connected to the mounting frame 21. The movable frame 23 is slidably inserted with the guide rod, and an auxiliary sliding groove is opened in the movable frame 23 at the guide rod.

[0027] The movable frame 23 is equipped with a bidirectional screw drive unit 231. Two sets of lateral pressing components 25 are driven by the bidirectional screw drive unit 231 inside the movable frame 23. The lateral pressing components 25 are slidably sleeved to the outside of the pressing roller assembly 27, and an auxiliary component 26 is slidably inserted below the lateral pressing components 25. The two sets of lateral pressing components 25 are symmetrically arranged.

[0028] Meanwhile, the auxiliary component 26 includes a second pressing block, on which auxiliary rods 262 and positioning rods 261 are sequentially installed on both sides of the top of the second pressing block, and a limiting element 263 is provided on the top of the positioning rods 261. It is worth noting that multiple ball bearings are evenly spaced at the bottom of the second pressing block.

[0029] Furthermore, the limiting member 263 includes a T-shaped magnetic block, one end of which is slidably disposed inside the positioning rod 261, and the other end of which is connected to a handle ring located outside the positioning rod 261. Magnetic protrusions are symmetrically installed on both sides of the bottom of the handle ring, and auxiliary grooves are provided on both sides of the handle ring at the corresponding magnetic protrusions.

[0030] Furthermore, a groove is provided inside one side of the positioning rod 261 at the T-shaped magnetic block. The bottom of the groove is provided with a magnetic material that attracts the T-shaped magnetic block. The top of the positioning rod 261 is provided with first magnetic grooves 264 symmetrically on both sides, and the other two sides of the top of the positioning rod 261 are provided with second magnetic grooves 265 symmetrically on both sides. The inner walls of the first magnetic groove 264 and the second magnetic groove 265 are provided with magnetic material that attracts the magnetic protrusion.

[0031] Meanwhile, the lateral pressing component 25 includes a sliding block, a first pressing block is installed at the bottom of the sliding block, a first sliding groove is provided through the first pressing block at the auxiliary rod 262, a second sliding groove is provided through the first pressing block at the positioning rod 261, and positioning blocks 251 are symmetrically installed on both sides of the second sliding groove.

[0032] Furthermore, a sliding groove is provided on the outer wall of the positioning rod 261 at the positioning block 251, and the sliding groove is parallel to the second magnetic groove 265.

[0033] It is worth noting that the specific structure and working principle of the hydraulic telescopic rod assembly 24 and the bidirectional screw drive unit 231 are all existing technologies that are currently publicly available on the market, so they will not be described in detail. In addition, the bidirectional screw drive unit 231 is dustproof and is not shown in the figure.

[0034] The first and second pressing blocks each have a groove on one side of their pressing surfaces, and multiple guide roller assemblies 28 are arranged at equal intervals in the groove.

[0035] In this embodiment, a lightweight sponge with cut sections is placed on the conveying unit 11, and the lightweight sponge is moved towards the cutting unit 12 by the conveying unit 11. The movable frame 23 and the corresponding pressure roller assembly 27 are driven by the hydraulic telescopic rod assembly 24 to move towards the top of the lightweight sponge until the bottom of the pressure roller assembly 27 is in contact with the top of the sponge. Then, the two sets of symmetrically arranged lateral pressure assemblies 25 are driven by the bidirectional screw drive unit 231 to move towards each other until the outer end face of the guide roller assembly 28 is in contact with the side wall of the sponge.

[0036] Furthermore, as the lateral pressing component 25 moves, it drives its auxiliary component 26 to move as well. Under its own weight, the bottom ball of the auxiliary component 26 is in contact with the top of the conveying unit 11, and the guide roller component 28 of the pressing surface of the auxiliary component 26 is in contact with the adjacent lightweight sponge.

[0037] When the auxiliary component 26 is not needed, move the limiting member 263 away from the positioning rod 261 until its magnetic protrusion is away from its positioning rod 261, then rotate the limiting member 263 until its auxiliary groove is aligned with its sliding groove, and then the auxiliary component can be removed.

[0038] When the auxiliary component is needed, it is inserted into the first pressing block. Before insertion, the limiting member 263 is rotated so that its auxiliary groove and sliding groove are parallel. After insertion, the limiting member 263 is rotated so that its auxiliary groove and sliding groove are staggered and its auxiliary groove is aligned with the first magnetic groove 264 and inserted. Then, the magnetic protrusion is magnetically connected to the first magnetic groove 264 and its limiting member 263 is limited.

[0039] The pressure roller assembly 27 provides vertical downward pressure to prevent the sponge from jumping during cutting; the lateral pressure assembly 25 provides horizontal lateral pressure above the sponge sidewall to prevent the sponge from shifting left or right during conveying or cutting; and the auxiliary assembly 26 increases the horizontal lateral pressure below the sponge sidewall to further prevent the sponge from shifting left or right during conveying or cutting.

[0040] Meanwhile, the guide roller assembly 28 and the pressure roller assembly 27 on the contact surfaces of the first and second pressing blocks convert sliding friction into rolling friction, reducing the resistance to the movement of the sponge during the limiting process and preventing the sponge surface from being scratched, roughened, or pressed into permanent indentations during the pressing and conveying process.

[0041] Furthermore, the auxiliary component 26 sags under its own weight, with the balls at its bottom contacting the surface of the conveyor unit 11. This allows it to automatically adapt to slight unevenness on the conveyor belt surface or variations in the thickness of the sponge itself, ensuring that the guide rollers at its bottom always effectively contact and guide the sponge.

[0042] The bidirectional lead screw drive unit 231 can synchronously drive two sets of symmetrical lateral pressing components 25 (including auxiliary components 26) to move in opposite directions or in opposite directions, adapting to lightweight sponges of different widths.

[0043] In this invention, by setting the auxiliary limiting component 2, the lightweight sponge placed on the parallel machine and about to enter the cutting unit is limited and pressed, and a certain pressure is provided on the top, the upper and lower sides of the sponge to prevent the sponge from jumping during cutting, and to prevent the sponge from shifting left and right during conveying or cutting.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
