Technical Field

[0001] The utility model relates to the technical field of foam plate rolling devices, in particular to a foam sheet finished product winding device. Background Art

[0002] Flexible polyurethane foam (Flexible Polyurethane Foam, referred to as polyurethane soft foam) refers to a type of soft polyurethane foam plastic with a certain elasticity. After being produced into a rectangular plate structure, it is widely used in express item protection, furniture cushioning and other occasions due to its own good flexibility, elasticity and low density.

[0003] During the processing, the formed foam board is in the shape of continuous strips. In order to facilitate storage and transportation and save space, it is usually wound into rolls. At present, for the winding of the foam board, after the foam board is discharged from the track, it is necessary to manually pull the end of the foam board and place it on the winding machine for operation. The operation is frequent, labor-intensive, and relatively low in efficiency. There are certain operational risks during pulling, which is not conducive to production and processing.

[0014] Preferably, a swing arm connected by a rotating shaft is provided below the support frame, and meshing teeth are provided on the swing arm; a rack meshing with the meshing teeth is provided below the mounting frame.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. By installing the first bracket at the discharge end of the track, the foam board is guided and received into the clamping assembly through the guiding channel, and after reaching the appropriate position, the clamping operation is completed by driving of the support frame. At the same time, by using the displacement of the support frame and the clamping assembly, the traction operation of the foam board is completed.

[0029] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0030] Specific embodiment 1: As shown in Figure 1-8 , a finished product winding device for foam thin plates includes: a first bracket 1, on which a guiding channel 2 is provided, and a supporting frame 3 that can be displaced in the discharging direction is provided on one side. A clamping assembly 4 is slidably connected to the supporting frame 3. The supporting frame 3 drives the clamping assembly 4 downward to clamp the end of the foam board and pulls it to the discharging end of the supporting frame 3. A second bracket 5 is provided in front of the first bracket 1;

[0031] After the finished foam board is output by the track, it is guided by the guiding channel 2 and enters the inside of the clamping assembly 4. When the end of the foam board extends beyond the right side of the clamping assembly 4 by an appropriate length, the supporting frame 3 triggers the clamping assembly 4 to clamp downward to complete the positioning of the foam board. Subsequently, the entire supporting frame 3 is displaced towards the winding machine. After reaching the designated position, the clamping assembly 4 is displaced to the right to realize the traction of the foam board, and the excess part of the foam board is inserted into the fixed part of the winding machine to achieve fixation. After the clamping assembly 4 is released, the winding machine can perform the winding operation. At this time, the supporting frame 3 and the clamping assembly 4 can be reset, effectively replacing manual operation, avoiding operation risks, and being more stable and efficient compared with manual traction.

[0033] Preferred embodiments, in combination with Figure 2 As shown, a first hydraulic cylinder 101 connected to the support frame 3 is provided behind the first support 1. The push rod of the first hydraulic cylinder 101 is fixed to the support frame 3. By the telescopic movement of the first hydraulic cylinder 101, the driving displacement of a part of the support frame 3 is realized, and the movement towards the fixed part of the winding machine is completed.

[0034] Preferred embodiments, in combination with Figure 2 As shown, stabilizing rods 301 are symmetrically provided on the left side of the support frame 3. A guiding hole is provided on the first support 1 where the first hydraulic cylinder 101 is located. The stabilizing rods 301 are inserted into the guiding holes to form a sliding connection, effectively improving the stress intensity and guiding stability of the support frame 3.

[0035] Preferred embodiments, in combination with Figure 2 As shown, a second hydraulic cylinder 302 is provided above the support frame 3, and a pressing plate 303 is provided on the push rod of the second hydraulic cylinder 302.

At the same time, the structural design of the pressing plate 303 and the slide rods 404 will not affect the displacement of the mounting frame 401 while ensuring the clamping effect, and the structural design is reasonable and ingenious.
