Description

Technical Field

[0001] This utility model relates to the technical field of rubber extrusion calendering, specifically to an aircraft tire rubber extrusion calendering device. Background Technology

[0002] During the production of aviation tire rubber, calendering is required. In the process of manufacturing rubber tires, the rubber raw materials need to be squeezed out by a calender to remove air bubbles, so as to avoid the air bubbles affecting the subsequent manufacturing and use of rubber tires.

[0003] For example, Chinese utility model patent CN220946315U discloses a rubber tire calender that facilitates the extrusion of air bubbles. It includes a calender structure for calendering rubber tire raw materials. The calender structure has material conveying structures on both sides for repeatedly conveying and calendering the rubber tire raw materials. The calender structure includes a housing with inlet and outlet holes on both sides. Inside the housing is a first pressure roller for calendering the rubber tire raw materials. A second pressure roller, driven and adjusted by a reciprocating motor, is located directly below the first pressure roller. A storage slot for a collection box is provided at the bottom of the housing. Inside the housing is an adjusting cylinder for driving and adjusting an adjusting block. A synchronous force-adjusting drive component is located on one side of the adjusting block, and a connecting block with a matching slot is located on one side of the drive component. The connecting block is matched with the matching block through the matching slot. This rubber tire calender that facilitates the extrusion of air bubbles achieves a scraping and collecting effect through the collection box.

[0004] However, due to the high ductility of rubber, the calendered rubber strip will have irregular arcs on both sides. These irregular arcs will affect the production quality. Therefore, it is necessary to trim the sides of the rubber strip to ensure that both sides are flat. The cutting of the rubber strip on both sides is usually done manually, which not only cannot guarantee that the cutting angle is flat, but also has the problem of low efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an aircraft tire rubber extrusion calendering device that improves the convenience of cutting excess rubber on both sides of the calendered rubber, improves the flatness of the calendered rubber, and enhances its practicality.

[0006] This utility model discloses an extrusion and calendering device for aviation tire rubber, comprising a worktable, two support plates symmetrically fixedly installed at the top of the worktable, a first roller and a second roller symmetrically rotated between the two support plates, and a cutting mechanism provided between the two support plates; the cutting mechanism includes a blade, the inner sidewall of the blade being tightly fitted with the inner sidewall of the second roller, a fixing rod fixedly installed between the two support plates, the fixing rod and the blade being rotatably and slidably connected, a limiting groove being obliquely opened at the top of the blade, a fixing column being slidably installed on the limiting groove, and each support plate being slidably connected to both ends of the fixing column through a limiting mechanism;

[0007] The limiting mechanism includes a fixed plate, a through hole obliquely opened on the support plate, a fixed column slidably connected to the through hole, a connecting plate fixedly installed on the outer side wall of the support plate, the fixed plate fixedly installed at one end of the fixed column, and a screw rod obliquely rotated and installed on the top of the fixed plate, the screw rod being screwed onto the connecting plate.

[0008] Both the first and second rollers are equipped with scraping mechanisms. The cutting mechanism includes a blade block. The inner wall of the blade block is tightly fitted with the inner wall of the second roller. A fixing rod is fixedly installed between the two support plates. The fixing rod and the blade block are rotatably and slidably connected. A limit groove is obliquely opened at the top of the blade block. A fixing column is slidably installed on the limit groove. Each support plate is slidably connected to both ends of the fixing column through a limit mechanism.

[0009] The limiting mechanism includes a fixed plate, a through hole obliquely opened on the support plate, a fixed column slidably connected to the through hole, a connecting plate fixedly installed on the outer side wall of the support plate, the fixed plate fixedly installed at one end of the fixed column, and a screw rod obliquely rotated and installed on the top of the fixed plate, the screw rod being screwed onto the connecting plate.

[0010] Both the first and second rollers are equipped with scraping mechanisms.

[0011] Preferably, the scraping mechanism includes a scraper, which is fixedly installed between two support plates. A first connecting groove and a second connecting groove are sequentially opened on the outer side wall of the scraper. A scraper blade is fixedly installed on the outer side wall of the scraper, and the scraper blade is in close contact with the outer side wall of the first roller. Through the first connecting groove opened on the scraper, it is convenient to perform preliminary rubber removal work on the rubber adhering to the first roller through one end of the outer side wall of the scraper. Through the contact between the scraper blade and the outer side wall of the first roller, the rubber adhering to the first roller is further removed, avoiding the rubber from adhering to the outer side wall of the first roller for a long time, thereby ensuring the calendering operation of the rubber by the first roller.

[0012] Preferably, a guide plate is fixedly installed between the two support plates, which facilitates the guiding operation of the rubber to be calendered.

[0013] Preferably, two vertical plates are symmetrically fixedly installed at the top of the workbench, and two third rollers are installed in parallel between the two vertical plates. A conveyor belt is tensioned between the two third rollers. The vertical plates are synchronously driven to rotate as the third rollers rotate, thereby supporting and conveying the rubber calendered by the first and second rollers.

[0014] Preferably, a first motor is fixedly installed at one end of the second roller. The first motor is fixedly installed on the outer wall of one of the support plates. When the first motor is started, it outputs power to synchronously drive the second roller to rotate. The rotating second roller comes into contact with the rubber, thereby causing the rubber to undergo calendering under the limiting position of the first roller.

[0015] Preferably, a second motor is fixedly installed at one end of the third roller. The second motor is fixedly installed on the outer wall of one of the vertical plates. The power output by the second motor drives the third roller to rotate synchronously.

[0016] Preferably, an anti-slip pad is fixedly installed on the outer wall of the fixed column. The anti-slip pad installed on the fixed column contacts the outer wall of the limiting groove opened on the blade, thereby preventing the blade from moving during the cutting operation and improving the stability of the blade in cutting the rubber after it has been calendered by the first and second rollers. Since the force exerted by the blade on the rubber is longitudinal, the blade will not move laterally under the limitation of the limiting groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: the cutting mechanism includes a blade block, the inner sidewall of the blade block is tightly fitted with the inner sidewall of the second roller, a fixing rod is fixedly installed between the two support plates, the fixing rod and the blade block are rotatably and slidably connected, a limit groove is obliquely opened at the top of the blade block, a fixing column is slidably installed on the limit groove, and each support plate is slidably connected to both ends of the fixing column through a limit mechanism;

[0018] The limiting mechanism includes a fixed plate, a through hole obliquely opened on the support plate, a fixed column slidably connected to the through hole, a connecting plate fixedly installed on the outer side wall of the support plate, the fixed plate fixedly installed at one end of the fixed column, and a screw rod obliquely rotated and installed on the top of the fixed plate, the screw rod being screwed onto the connecting plate.

[0019] Both the first and second rollers are equipped with scraping mechanisms. Attached Figure Description
