Description

Technical Field

[0001] This utility model relates to tape production technology, specifically a tape production adhesive coating device. Background Technology

[0002] Adhesive tape consists of two parts: a substrate and an adhesive. It is used to bond two or more unconnected objects together.

[0003] During normal industrial production, the glue coating device may need to be shut down for inspection or maintenance. At this time, the glue coating roller will still be in contact with the substrate belt. However, the glue on the substrate belt will solidify after being in contact with air for a long time, causing the substrate belt to stick to the glue coating roller. As a result, when the equipment is restarted, the substrate belt cannot be moved or is wrapped around the glue coating roller, affecting the normal operation of the equipment. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a tape production coating device that can swing the coating roller, allowing it to be lifted during equipment shutdown and maintenance, thereby separating it from the substrate tape and preventing the substrate tape from sticking firmly to the coating roller.

[0005] To achieve the above technical objectives, this utility model adopts the following technical solution: a tape production coating device, set on a machine base, with side frames and a drive unit on both sides of the machine base, and a main shaft rotatably connected between the two side frames. The drive unit drives the main shaft to rotate, and swing arms are fixed at both ends of the main shaft. A coating roller is rotatably connected to one end of the swing arm relative to the main shaft. The coating roller is driven to rotate by a motor, which is fixed to the swing arm. A glue infeed unit is provided above the coating roller for coating adhesive onto the coating roller. A support roller is provided below the coating roller for supporting the substrate tape. The coating roller is used to coat the substrate tape with adhesive.

[0006] Preferably, the drive unit includes a cylinder and a connecting rod. The cylinder is hinged to the machine base, the end of the cylinder piston rod is hinged to one end of the connecting rod, and the other end of the connecting rod is fixedly connected to the main shaft.

[0007] Preferably, both ends of the coating roller are provided with limiting plates.

[0008] Preferably, the glue dispensing unit includes a support plate, with both ends of the support plate fixed to the ends of two swing arms. A uniform distribution plate is provided on both sides of the bottom of the support plate. The bottom end of the uniform distribution plate is in contact with the glue coating roller, and the side edge of the uniform distribution plate is in contact with a limiting plate. The glue coating roller, the bottom surface of the support plate, the two uniform distribution plates, and the two limiting plates form a receiving cavity, which is filled with adhesive. The uniform distribution plate is used to uniformly coat the adhesive in the receiving cavity onto the glue coating roller. Several glue dispensing pipes are provided above the support plate, and the glue dispensing pipes communicate with the receiving cavity.

[0009] Preferably, the support plate is provided with a glue outlet.

[0010] Preferably, the two ends of the support roller are rotatably connected to the floating block, the floating block is slidably engaged with the floating groove, the floating groove is located at the top of the adjusting frame, the adjusting frame is fixed to the machine base, the bottom of the floating groove is provided with a lifting spring, the bottom end of the lifting spring is fixed to the floating groove, and the top end of the lifting spring is fixed to the floating block.

[0011] In summary, this utility model achieves the following technical effects:

[0012] The adhesive tape production coating device of this utility model adopts a drive unit that can swing the coating roller, so that the coating roller is lifted when the equipment is stopped for maintenance, thereby separating the coating roller from the substrate tape, preventing the substrate tape from sticking firmly to the coating roller, and ensuring the normal operation of the equipment in the future.

[0023] Example 1:

[0024] like Figure 1As shown in Figure 2, a tape production coating device is installed on a machine base 1. The machine base 1 has side frames 4 and a drive unit on both sides. A main shaft is rotatably connected between the two side frames 4. The drive unit drives the main shaft to rotate. A swing arm 5 is fixed at both ends of the main shaft. A coating roller 7 is rotatably connected to one end of the swing arm 5 relative to the main shaft. The coating roller 7 is driven to rotate by a motor 6. The motor 6 is fixed to the swing arm 5. A glue inlet unit is provided above the coating roller 7. The glue inlet unit is used to coat the adhesive onto the coating roller 7. A support roller 13 is provided below the coating roller 7. The support roller 13 is used to support the substrate tape. The coating roller 7 is used to coat the adhesive onto the substrate tape.

[0025] The tape production coating device in this embodiment uses a drive unit that can swing the coating roller 7, so that the coating roller 7 can be lifted when the equipment is stopped for maintenance, thereby separating the coating roller 7 from the substrate tape and preventing the substrate tape from sticking firmly to the coating roller 7, ensuring the normal operation of the equipment in the future.

[0026] The drive unit includes a cylinder 2 and a connecting rod 3. The cylinder 2 is hinged to the machine base 1. The piston rod end of the cylinder 2 is hinged to one end of the connecting rod 3, and the other end of the connecting rod 3 is fixedly connected to the main shaft.

[0027] Both ends of the coating roller 7 are provided with limiting plates 8; the setting of the limiting plates 8 can make the coating roller 7 and the support roller 13 accurately aligned, and can help form a receiving cavity.

[0028] like Figure 3 As shown, the glue-feeding unit includes a support plate 9, with both ends of the support plate 9 fixed to the ends of two swing arms 5 respectively. A uniform distribution plate 10 is provided on both sides of the bottom of the support plate 9. The bottom end of the uniform distribution plate 10 is in contact with the glue-applying roller 7, and the side of the uniform distribution plate 10 is in contact with the limiting plate 8. The glue-applying roller 7, the bottom surface of the support plate 9, the two uniform distribution plates 10, and the two limiting plates 8 form a receiving cavity. The receiving cavity is filled with adhesive. The uniform distribution plate 10 is used to uniformly coat the adhesive in the receiving cavity onto the glue-applying roller 7. Several glue-feeding pipes 11 are provided above the support plate 9, and the glue-feeding pipes 11 communicate with the receiving cavity.

[0029] The support plate 9 is provided with an adhesive discharge port; the adhesive discharge port is connected to an external negative pressure pump, so that when the equipment stops, the adhesive in the receiving cavity can be extracted to prevent the adhesive from solidifying in the receiving cavity and causing blockage.

[0030] The support roller 13 is rotatably connected to the floating block 14 at both ends. The floating block 14 is slidably engaged with the floating groove, which is located at the top of the adjusting frame 12. The adjusting frame 12 is fixed to the machine base 1. A lifting spring 15 is provided at the bottom of the floating groove. The bottom end of the lifting spring 15 is fixed to the floating groove, and the top end of the lifting spring 15 is fixed to the floating block 14.
