DETAILED DESCRIPTION
[0031] The following description will be made in conjunction with the accompanying drawings Figures 1-5 The application is further described in detail.
[0032] The application discloses a flatting machine for polyurethane sponge.
[0033] Embodiment 1
[0034] Referring to Figures 1-3 A flatting machine for polyurethane sponge comprises a cutting table 1, a moving frame 2 and a driving mechanism 3. The cutting table 1 is used for placing the sponge to be cut. The moving frame 2 is slidably connected to the cutting table 1 along the length direction of the cutting table 1. The driving mechanism 3 is used for driving the moving frame 2 to slide relative to the cutting table 1. The moving frame 2 is provided with a cutter 25, which extends along the width direction of the cutting table 1. The driving mechanism 3 is used for driving the moving frame 2 to slide relative to the cutting table 1. The driving mechanism 3 can be a hydraulic cylinder, a pneumatic cylinder or a cooperation assembly of a motor and a gear rack.
[0035] The moving frame 2 is further provided with an auxiliary roller 21 and a driving motor 22. The auxiliary roller 21 is rotatably connected to the moving frame 2 with its center axis as the rotation axis. The auxiliary roller 21 extends along the width direction of the cutting table 1. The auxiliary roller 21 is located obliquely above the cutter 25 and is used for abutting against the waste material being wound. The output end of the driving motor 22 is connected to the auxiliary roller 21 and is used for driving the auxiliary roller 21 to rotate. The rotating direction of the auxiliary roller 21 is opposite to the winding direction of the waste material.
[0036] The moving frame 2 is provided with a bearing table 23, which is used for bearing the worker. Thus, the worker can move together with the cutter 25 during the working process of the flatting mechanism. On one hand, the worker can pay attention to the machine at any time. On the other hand, the worker can assist in winding the cut waste material.
[0037] Further, the moving frame 2 is provided with a flatting roller 24, which extends along the width direction of the cutting table 1. The flatting roller 24 is used for abutting against the upper surface of the sponge to be cut. The cutter 25 is located between the flatting roller 24 and the auxiliary roller 21. Thus, the flatting roller 24 is used for pressing the cut sponge. On one hand, the flatting roller 24 can prevent the cut sponge from being displaced during the cutting process. On the other hand, the upper surface of the cut sponge can be on the same height level, so that the cutting precision is improved.
[0038] In the embodiment, the flatting roller 24 is rotatably connected to the moving frame 2. Thus, the flatting roller 24 and the sponge to be cut are in rolling friction, so that the relative friction between the flatting roller 24 and the sponge to be cut is reduced. The smoothness of the machine operation is ensured, and the abrasion between the cut sponge and the flatting roller 24 is reduced.
[0039] It can be understood that, in other embodiments, the flatting roller 24 can also be stationary relative to the moving frame 2.
[0040] The implementation principle of the embodiment 1 is that when the polyurethane sponge is flattened, the polyurethane sponge to be processed is placed on the cutting table 1, then the driving mechanism 3 is started to drive the moving frame 2 to move relative to the cutting table 1; after the moving frame 2 starts to move, the cutter 25 cuts the polyurethane sponge pad; at the same time, the worker standing on the bearing table 23 assists to roll up the end of the waste cut off; then the worker, the flattening roller 24, the cutter 25 and the auxiliary roller 21 move along with the moving frame 2 in the cutting direction, and in the moving process, the cutting of the polyurethane sponge is completed at the same time as the waste is wound up for processing.
[0041] Embodiment 2
[0042] With reference to Figure 4 The difference between the embodiment and the embodiment 1 is that the flattening roller 24 is slidably connected to the moving frame 2 in the height direction of the moving frame 2. The moving frame 2 is provided with a positioning piece 4, and the positioning piece 4 is used to fix the flattening roller 24 to the moving frame 2, so as to facilitate the adjustment of the height of the flattening roller 24 according to the thickness of the polyurethane sponge, and improve the use flexibility of the flattening roller 24.
[0043] Specifically, in the embodiment, the positioning piece 4 includes a fixed part 41 and a movable part 42. The fixed part 41 is fixedly connected to the moving frame 2, and a threaded hole 411 is formed through the fixed part 41 in the height direction of the moving frame 2. The movable part 42 is a screw rod structure, and the movable part 42 is rotatably connected to the end of the flattening roller 24. The movable part 42 extends in the height direction of the moving frame 2, and the movable part 42 is threadedly connected with the threaded hole 411 of the fixed part 41. When it is necessary to adjust the height of the flattening roller 24, the movable part 42 can be screwed relative to the fixed part 41.
[0044] It can be understood that in the embodiment, the positioning piece 4 is provided with two, and the two positioning pieces 4 are respectively connected to the two ends of the flattening roller 24.
[0045] With reference to Figure 5 Further, in the embodiment, the moving frame 2 is provided with a winding roller 26, and the winding roller 26 extends in the width direction of the cutting table 1.
[0046] The connecting plate 5 is obliquely arranged, and the sliding groove 51 is formed in the connecting plate 5. In the direction from the bottom to the top of the moving frame 2, the distance between the center axis of the sliding groove 51 and the auxiliary roller 21 gradually increases. The two ends of the winding roller 26 are rotationally connected with sliding blocks 261, and the sliding blocks 261 are slidably connected in the sliding groove 51. Therefore, the winding roller 26 is slidably connected with the moving frame 2, and in the direction from the bottom to the top of the moving frame 2, the distance between the path of the winding roller 26 moving relative to the moving frame 2 and the center axis of the auxiliary roller 21 gradually increases, so that the waste material is wound on the winding roller 26 during the working of the calender.
[0047] Further, the upper end of the sliding groove 51 penetrates the upper side wall of the connecting plate 5, and the upper side wall of the connecting plate 5 is detachably connected with an abutting piece 53 through a bolt. The sliding groove 51 is provided with an abutting spring 52, and the two ends of the abutting spring 52 abut against the abutting piece 53 and the sliding block 261 respectively. Before the working of the calender, the sliding block 261 connected with the winding roller 26 is fitted into the sliding groove 51, then the abutting spring 52 is put into the sliding groove 51, and finally the abutting piece 53 is installed on the connecting plate 5. During the working of the calender, with the increase of the waste material wound on the winding roller 26, the winding roller 26 gradually moves upward, and the abutting spring 52 is compressed during the upward movement. Under the elastic force of the abutting spring 52, the winding roller 26 and the auxiliary roller 21 clamp the waste material wound on the winding roller 26, so as to ensure that the waste material is tightly wound on the winding roller 26, and the subsequent storage and transportation of the waste material are facilitated.
[0048] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
