Description

Technical Field

[0001] The utility model relates to the field of sandpaper compounding, in particular to a sandpaper compounding device. Background Art

[0002] The multi-layer composite structure of sandpaper includes a frosting layer for frosting and a rubber coating layer for support. Glue is coated between the frosting layer and the rubber coating layer, and the glue tightly fits the frosting layer and the rubber coating layer.

[0003] During the adhesive coating process, the adhesive needs to be in a heated state before being coated on the rubber coating layer to prevent the adhesive from solidifying. Therefore, a heating device is generally provided in the coating roller to ensure that the adhesive can be coated on the rubber coating layer in a stable state. However, the coating roller also needs to rotate to drive the adhesive on its surface to move to a state of abutting against the rubber coating layer. Therefore, the synchronous setting of the rotating device and the heating device makes the structure of the coating roller complicated. Utility Model Content

[0004] In order to simplify the structure of a coating roller, the utility model provides a sandpaper composite device.

[0005] The utility model provides a sandpaper composite device adopts the following technical solution:

[0006] A sandpaper composite device includes a feeding component, a coating component and a composite component, wherein the coating component includes a supporting roller, a coating roller and a glue coating groove, wherein the supporting roller is located directly below the coating roller, the glue coating groove is used to receive adhesive, a heating element is provided on the bottom wall of the glue coating groove, one end of the glue coating groove is open and abuts against the peripheral wall of the coating roller, and a gap is left between the glue coating groove and the coating roller.

[0007] The loading component transfers the coating layer that needs to be coated with adhesive to the coating roller, and the adhesive in the coating groove flows to the coating roller. When the coating layer slides to the position abutting the coating roller, the adhesive on the coating roller transfers and adheres to the coating layer, thereby completing the coating action. Since a heating element is provided on the bottom wall of the coating groove, the adhesive is in a heated state before flowing to the coating roller. At the same time, the coating roller is not restricted by the heating device when rotating, making the rotation structure of the coating roller simpler, which is conducive to simplifying the structure of the coating roller. At the same time, the coating groove that receives the adhesive is equipped with an external heating element. When the heating element is aged, the heating element can be directly repaired outside the coating roller, making the overall repair and maintenance of the composite device more convenient and quick.

[0008] In this embodiment, the coating assembly also includes a driving cylinder for driving the support roller to move. The driving cylinder drives the support roller to move in a vertical direction, so that the support roller can move toward or away from the coating roller, thereby controlling the distance between the support roller and the coating roller.

[0009] Preferably, the heating element includes a heating box, which is a long rectangular box. The heating box extends along the length direction of the coating roller, and one side wall of the heating box is the bottom wall of the glue coating groove, and two baffles are provided on the side wall of the heating box, one side of the baffle is in contact with the coating roller, and the side of the baffle in contact with the coating roller is an arc-shaped surface that fits the coating roller.

[0010] During the coating process, the heating box and the coating roller are relatively still. Before coating, the angle of the heating box is adjusted so that the arc surface of the baffle fits with the coating roller. The baffle and the side wall of the heating box cooperate with the peripheral wall of the coating roller to form a coating groove for receiving the adhesive. The peripheral wall of the coating roller is used to construct the coating groove, and the coating roller is heated by the heating box at the same time. These complement each other and are conducive to simplifying the structure. At the same time, when the adhesive drips into the coating groove and accumulates to a certain amount, the part of the coating roller located between the baffles can be coated with the adhesive. The coating roller is coated by the glue groove, which is conducive to improving the utilization rate of the heating element.

[0011] In this embodiment, a magnetic component is provided on the heating box, and a switch is electrically connected to the magnetic component. The baffle is a metal plate. When coating is required, the switch is turned on so that the magnetic component has suction force on the metal plate, thereby preventing the baffle from being on the heating box and making the curved surface fit with the coating roller, thereby completing the fixation of the baffle.

[0012] In this embodiment, a glue dripping tube is arranged directly above the heating box. A heating wire is arranged in the glue dripping tube to heat the adhesive in the glue dripping tube to prevent solidification. The glue dripping tube is located directly above the midpoint of the heating box along the length direction.

[0013] Preferably, a scraper is provided on one side of the heating box, a distance is left between the scraper and the coating roller, and the scraper is arranged between the two baffles.

[0014] The scraper serves as a carrier for the adhesive between the heating box and the coating roller, avoiding the situation where the heating box is set in an irregular shape, which makes the heating box difficult to process and assemble. At the same time, when the scraper is aged, the scraper can be replaced separately, avoiding the situation where replacing the heating device leads to increased maintenance costs.

[0015] Preferably, the sandpaper composite device comprises a frame, the heating box is connected to a rotation, and the amount of glue brought to the composite layer by the coating roller can be adjusted by the distance between the scraper and the coating roller after the heating box rotates.

[0016] The heating box is turned to adjust the distance between the tip of the scraper and the coating roller, thereby adjusting the amount of glue that can pass between the tip of the scraper and the coating roller, and further adjusting the amount of adhesive applied by the coating roller to the composite layer, making the overall adaptability of the device higher.

[0017] Preferably, the feeding assembly includes a first roller, a second roller, a third roller and a fourth roller, the first roller and the second roller are located in the same vertical space, an entrance for the rubber layer to enter is left between the first roller and the second roller, the third roller is lower than the bottom end of the entrance, the top end of the fourth roller is higher than the top end of the third roller, and the third roller is located between the fourth roller and the second roller.

[0018] The rubber layer is passed into the sandpaper composite device from the entrance between the first roller and the second roller, then passes through the bottom of the third roller and then from the top of the fourth roller, and then is passed between the coating roller and the supporting roller. The third roller serves as the middle roller between the first roller and the fourth roller, pressing down the rubber layer to achieve the effect of tightening the rubber layer, so that the rubber layer is in a tightened state.

[0019] Preferably, the composite assembly includes a conveyor belt and a pressure roller arranged on the conveyor belt, and the pressure roller abuts against the upper surface of the conveyor belt.

[0020] The frosted layer and the rubber coating layer are simultaneously transferred to the conveyor belt, and the conveyor belt cooperates with the pressure roller to press the frosted layer and the rubber coating layer. At the same time, the conveyor belt can also be used to support and transport the frosted layer and the rubber coating layer, which is beneficial to improve the utilization rate of the conveyor belt.

[0021] Preferably, the loading assembly also includes a fifth roller, a sixth roller and a seventh roller for conveying the frosted layer, the frosted layer is rolled up on the fifth roller, the sixth roller is higher than the fifth roller and the seventh roller, the seventh roller is close to the feed end of the conveyor belt, and the fifth roller, the sixth roller and the seventh roller are all suspended above the conveyor belt.

[0022] The frosted layer is rolled up on the fifth roller, one end of the frosted layer passes over the sixth roller and the seventh roller, and is finally conveyed to the conveyor belt synchronously with the rubber layer. The conveyor belt and the pressure roller cooperate to press the rubber layer and the frosted layer, and the sixth roller can tighten the frosted layer to achieve a better composite effect. The feeding structure of the frosted layer is arranged above the conveyor belt, and the vertical space of the frame is used for feeding, which is conducive to reducing the ground space occupied by the sandpaper compounding device.

[0023] Preferably, the composite assembly further comprises a driving cylinder for driving the pressing roller to move in a vertical direction.

[0024] The driving cylinder drives the pressure roller to move in the vertical direction, so that the pressure roller is close to or away from the conveyor belt, thereby adjusting the distance from the bottom wall of the pressure roller to the upper surface of the conveyor belt. The distance between the pressure roller and the conveyor belt can adapt to the multi-layer composite structure to be processed.

[0025] Preferably, two pressing rollers are provided, and the two pressing rollers are respectively arranged at two ends of the conveyor belt along the length direction.
