Description

Technical Field

[0001] The present application relates to the technical field of sponge processing, and provides a side film collecting mechanism for a sponge foaming machine. Background Art

[0002] After the high-damping polyurethane slow-rebound sponge is foamed and formed, it moves on the conveyor belt. In order to ensure the square rate of the sponge, auxiliary conveyor belts are arranged on both sides of the conveyor belt, and a plastic film (abbreviated as side film) is attached to one end of the auxiliary conveyor belt close to the discharge port of the foaming machine. Since the surface of the sponge is relatively hot when it is just formed, the side film adheres to the sponge. As the sponge is conveyed on the conveyor belt, the setting of the side film can reduce the appearance of arcs at the edges and corners of the sponge, thereby ensuring the forming rate of the sponge.

[0003] In order to peel off the side film from the sponge and reuse it, winding devices are arranged on both sides of the conveyor belt. The existing winding device includes a winding roller and a driving structure for driving the winding roller to rotate. During use, one end of the side film adhered to the sponge is first connected to the winding roller, and then the driving structure is started, and the winding roller rotates, so that the side film is wound around the surface of the winding roller.

[0004] When the side film needs to be removed from the winding roller, since the side film is wound around the outer wall of the winding roller, it is not conducive for the staff to remove the side film from one end of the winding roller, reducing the work efficiency. Utility Model Content

[0005] In order to facilitate the removal of the collected side film from the winding roller, the present application provides a side film collecting mechanism for a sponge foaming machine.

[0006] The side film collecting mechanism for a sponge foaming machine provided by the present application adopts the following technical solutions:

[0007] A side film collecting mechanism for a sponge foaming machine includes a frame, a rotating disk rotatably installed on the frame, an intermediate roller fixed above the rotating disk, a mounting disk fixed on the side of the intermediate roller away from the rotating disk, and a driving member for driving the rotating disk to rotate. A plurality of winding rollers are arranged between the mounting disk and the rotating disk, and all the winding rollers are circumferentially spaced apart around the intermediate roller; a sleeve is slidably installed on the outer wall of the intermediate roller, a plurality of connecting rods are hinged to the sleeve, and the side of the connecting rod away from the sleeve is hinged to the intermediate roller; the intermediate roller is provided with a moving member for driving the sleeve to slide.

[0008] By adopting the above technical solution, when it is necessary to remove the side film from the winding roller, the movable member is used to drive the sleeve to slide on the intermediate roller; since a connecting rod is hinged between the sleeve and the winding roller, the side of the winding roller facing the intermediate roller can be moved closer to / away from during the rotation of the sleeve; so that the inner diameter after the side film is wound is larger than the outer diameter formed by the plurality of winding rollers, causing the side film to become loose, thereby facilitating the extraction of the wound side film to separate the side film from the take-up roller and improving the operation convenience.

[0009] Optionally, a tension spring is arranged between the intermediate roller and one of the winding rollers, and the elastic force of the tension spring is used to drive the side of the winding roller facing the intermediate roller to move.

[0010] By adopting the above technical solution, due to the continuous accumulation of the side film during the winding process, the outer diameter of the wound side film continuously increases, and the elastic force of the tension spring can ensure that the side film maintains a stable tension during the winding process, thereby improving the winding quality.

[0011] Optionally, a limiting block is arranged on the inner wall of the sleeve, and a limiting groove for the limiting block to slide is formed in the intermediate roller.

[0012] By adopting the above technical solution, the cooperation of the limiting block and the limiting groove can reduce the situation that the sleeve rotates freely on the outer wall of the intermediate roller; thereby increasing the stability of the sleeve wound on the outer walls of all the winding rollers.

[0013] Optionally, a plurality of anti - detachment grooves are formed in the side wall of the mounting disc, an anti - detachment rod is slidably mounted in the anti - detachment groove, and the anti - detachment rod is used to abut against the side wall of the side film; the mounting disc is provided with a telescopic assembly for driving the anti - detachment rod to slide.

[0014] By adopting the above technical solution, the telescopic assembly can drive the anti - detachment rod to move in the anti - detachment groove, enabling the anti - detachment rod to abut against the outer wall of one side of the side film, so that the side film is located between the anti - detachment rod and the rotating disc, reducing the situation that the side film moves up and down during the winding process and improving the winding quality of the side film.

[0015] Optionally, the telescopic assembly includes a first gear, a rack and a rotating member, and a driving groove communicating with the anti - detachment groove is formed in the mounting disc; the first gear is rotatably mounted in the driving groove, the rack is mounted on the side wall of the anti - detachment rod and is used to mesh with the first gear; the rotating member is used to rotate the first gear.

[0016] By adopting the above technical solution, by rotating the first gear through the rotating member, the rack can be moved under the meshing of the first gear, making the rack move closer to / away from the side of the anti - detachment groove; when the anti - detachment rod is removed from the side of the side film, it is convenient to remove the side film from the winding roller.

[0017] Optionally, the rotating member is provided as a first motor, and the first motor is mounted on the mounting disc and connected to the first gear.

[0018] By adopting the above technical solution, the first motor can drive the first gear to rotate, so that the anti-disengagement rod can enter / exit the anti-disengagement groove, and the abutment between the anti-disengagement rod and the side film can be cancelled.

[0019] Optionally, the rotating member includes a second gear, a spring and a rotating rod. One end of the rotating rod is fixed to the first gear, and the other end of the rotating rod passes through the mounting disc and is exposed to the outside; a fixed cylinder is sleeved on the outer wall of the rotating rod, and the second gear is fixed to one end of the fixed cylinder close to the mounting disc; the mounting disc is provided with a tooth groove for inserting the second gear, and the spring is installed between the fixed cylinder and the rotating rod, and the elastic force of the spring is used to drive the second gear to be inserted into the tooth groove under normal conditions.

[0020] By adopting the above technical solution, when the first gear rotates, the fixed cylinder is moved toward the side away from the mounting disc so that the second gear cancels the insertion with the tooth groove; at this time, the first gear can be rotated to change the position of the anti-disengagement rod in the anti-disengagement groove; and after the anti-disengagement rod is adjusted to the required position, the acting force applied to the fixed cylinder is stopped; at this time, the elastic force of the spring can drive the second gear to be inserted into the tooth groove, thereby reducing the situation that the first gear rotates freely.

[0021] Optionally, the rotating disc is provided with a plurality of ventilation holes.

[0022] By adopting the above technical solution, by providing the ventilation holes, the side of the side film in contact with the rotating disc can be cooled, the heat on the side film can be reduced, and the bonding of the side films together can be reduced, which affects the secondary use.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By connecting the sleeve to multiple sets of winding rollers, when the side film is taken off from the winding roller, the movable member is used to drive the sleeve to slide on the middle roller; the inner diameter of the wound side film is larger than the outer diameter formed by the multiple winding rollers, so that the side film becomes loose, thus facilitating the extraction of the rolled side film to separate the side film from the winding roller and improving the operation convenience;

[0025] 2. By providing the anti-disengagement rod, by abutting the anti-disengagement rod against the outer wall of one side of the side film, the side film is located between the anti-disengagement rod and the rotating disc, reducing the situation that the side film moves up and down during the winding process and improving the winding quality of the side film.
