Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing sheet production, in particular to a roller forming machine for producing shock-absorbing sheets. Background Art

[0002] Automotive shock absorbers are a very important product in the current automotive NVH solution. They play a vital role in reducing the noise during driving and can significantly improve the sound quality when the car door is closed.

[0003] At present, there are basically two ways to produce shock-absorbing sheets: the first is to use a double-roll calender to extrude the heated and molten rubber into sheets, and at the same time, the constraint layer and the backing paper are pasted on the rubber layer. The advantage is that it is formed in one step, with fewer processes and less equipment;

[0004] However, the disadvantages are high energy consumption, high requirements on the strength of the backing paper, and the inability to perfectly align the sides of the film, which causes great inconvenience to the subsequent use of the vehicle manufacturer;

[0005] The second method is to use an extrusion die to extrude a film with precise dimensions, and then laminate the constraint layer, adhesive layer and backing paper together. The laminating part is formed by upper and lower double rollers. This method can ensure the stable quality of the product side.

[0006] However, when the machine is turned on and the product thickness changes, since the adjustable range of the spacing between the upper and lower rollers is very small, it is only suitable for production conditions with large output and no frequent model changes. If you want to frequently change product models or the product thickness span is relatively large, this type of equipment will instead cause a large waste of machine head material.

[0033] In order to facilitate operation and reduce noise, the gear material is made of POM;

[0034] When in use, the motor 61 is started, and the output end of the motor 61 rotates forward to drive the rotating shaft 62 to rotate forward, and then the driving gear 63 rotates forward through the forward rotation of the rotating shaft 62, and then the lower pressure roller coaxial gear 64 and the reversing gear 65 are reversed, and then the lower pressure roller body 67 is reversed through the reverse rotation of the lower pressure roller coaxial gear 64, and at the same time, the upper pressure roller coaxial gear 66 is driven to rotate forward through the reverse rotation of the reversing gear 65, and then the upper pressure roller body 610 is driven to rotate forward, and then the product is roll-formed by the synchronization of the reverse rotation of the lower pressure roller body 67 and the forward rotation of the upper pressure roller body 610;

[0035] The function of synchronous reverse rotation of the lower pressing roller body 67 and the upper pressing roller body 610 is realized, which can ensure the synchronization of the linear speed of the constraining layer and the liner paper, effectively avoid product curling due to speed difference, and facilitate the subsequent use of the roll-formed product.

[0038] When in use, the motor 61 is started, and the output end of the motor 61 reverses to drive the rotating shaft 62 to reverse, and then the rotating shaft 62 reverses to drive the one-way gear 72 to rotate, thereby driving the reciprocating screw rod 71 to rotate, and then the reciprocating screw rod 71 rotates to drive the slider 73 to move synchronously in the same direction or in the opposite direction, thereby driving the connecting rod 74 to move, and then the sliding plate 75 is driven to move by the movement of the connecting rod 74, thereby driving the support rod 76 to move, and then the support arm 69 is driven to rotate by the movement of the support rod 76, thereby driving the upper pressure roller body 610 to rotate to a suitable position with the fixed shaft 68 as the axis, and adjusting the spacing between the upper pressure roller body 610 and the lower pressure roller body 67.

[0042] Working principle: When in use, according to the actual model of the product, the motor 61 is started, the output end of the motor 61 is reversed to drive the rotating shaft 62 to reverse, and then the rotating shaft 62 is reversed to drive the one-way gear 72 to rotate, so that the support arm 69 rotates, and then the upper pressure roller body 610 is rotated to a suitable position, and the distance between the upper pressure roller body 610 and the lower pressure roller body 67 is adjusted;

[0043] Then the output end of the motor 61 rotates forward to drive the rotating shaft 62 to rotate forward, and then the rotating shaft 62 rotates forward to drive the driving gear 63 to rotate forward, so that the lower pressure roller coaxial gear 64 and the reversing gear 65 are reversed, and then the lower pressure roller body 67 is reversed by the reversal of the lower pressure roller coaxial gear 64. At the same time, the reversal of the reversing gear 65 drives the upper pressure roller coaxial gear 66 to rotate forward, and then drives the upper pressure roller body 610 to rotate forward, and then the lower pressure roller body 67 is reversed and the upper pressure roller body 610 is rotated forward synchronously, and the product is roll-formed.
