[0070] Under the driving of the first driving shaft 19 and the second driving shaft 20, the first connecting rod 21 and the second connecting rod, the third connecting rod 22 and the fourth connecting rod move, thereby driving the first transmission rod 13 and the second transmission rod 14, the third transmission rod 15 and the fourth transmission rod 16 to move.

[0071] By fixing the first transmission rod 13 with the first connecting rod 21 and the second transmission rod 14 with the second connecting rod, and fixing the first connecting rod 21 and the second connecting rod with the first driving shaft 19, the movement of the first driving shaft 19 can drive the whole distance adjusting assembly to move, so that the integrity of the distance adjustment is better.

[0072] As a specific embodiment, the first driving part 23 is a first telescopic rod and a telescopic motor, the first driving shaft 19 is provided with a sliding groove on both sides, the first driving shaft 19 is connected with the first telescopic rod, the telescopic motor drives the first telescopic rod to extend or retract, then drives the first driving shaft 19 to move towards the second roller 2 or away from the second roller 2, the first connecting rod 21 and the second connecting rod move accordingly, thereby driving the first transmission rod 13 and the second transmission rod 14 to move, at this time, the first bearing seat 9 and the third bearing seat 11 move accordingly and realize the position adjustment of the first roller 1, so as to adjust the distance between the first roller 1 and the second roller 2; the second driving shaft 20 is provided with a sliding groove on both sides, the second driving shaft 20 is connected with the second telescopic rod, the telescopic rod drives the second driving shaft 20 to move, the third connecting rod 22 and the fourth connecting rod move accordingly, thereby driving the third transmission rod 15 and the fourth transmission rod 16 to move, further, the second bearing seat 10 and the fourth bearing seat 12 move accordingly and realize the position adjustment of the second roller 2.

[0073] Specifically, the number of the first telescopic rod can be one or more, preferably three, two of which are arranged at the two ends of the first driving shaft 19, and the third one is arranged at the middle position of the first driving shaft 19, which not only makes the force of the first driving shaft 19 more uniform, but also enables the first driving shaft 19 to work normally when one or two of them fail; similarly, the number of the second telescopic rod can be one or more, preferably three, two of which are arranged at the two ends of the second driving shaft 20, and the third one is arranged at the middle position of the second driving shaft 20, which not only makes the force of the second driving shaft 20 more uniform, but also enables the second driving shaft 20 to work normally when one or two of them fail.

[0074] The base 36 is internally provided with a first transmission plate, the first transmission plate is provided with a first rack, the first driving shaft 19 is provided with a first gear engaged with the first rack, the rotary motor drives the first gear to rotate, thereby realizing the movement of the first driving shaft 19 along the first rack; and is also provided with a second transmission plate, the second transmission plate is provided with a second rack, the second driving shaft 20 is provided with a second gear engaged with the second rack, the rotary motor drives the second gear to rotate, thereby realizing the movement of the second driving shaft 20 along the second rack.

[0076] In addition, the first rack and the first gear here can be arranged on only one side of the first driving shaft 19, and the other side is provided with a sliding groove for support, or can be arranged on both sides of the first driving shaft 19, which can further ensure the same direction movement.

[0077] To improve the accuracy of the pitch adjustment, the pitch adjustment precision of the first pitch adjustment component and the second pitch adjustment component can be set to different forms. One component can achieve coarse adjustment of the pitch, and the other can achieve fine adjustment of the pitch. This technical solution can be implemented by setting different extension strokes of the first telescopic rod and the second telescopic rod, or by setting different tooth pitches on the first rack and the second rack. When the first gear and the second gear rotate at the same angle, the movement distance of the first gear on the first rack and the movement distance of the second gear on the second rack are different.

[0078] In one embodiment, the first drive shaft 19 is slidably connected to a plurality of third support frames 25, the third support frames 25 being used to support the first drive shaft 19, and the second drive shaft 20 is fitted with a plurality of fourth support frames 26, the fourth support frames 26 being used to support the second drive shaft 20, and both the third support frames 25 and the fourth support frames 26 are fixedly connected to the base 36.

[0079] Specifically, the first drive shaft 19 may have a groove that mates with the third support frame 25 and slides on the third support frame, or the first drive shaft 19 may have a protrusion that mates with a sliding groove on the third support frame 25 and slides. The connection method between the second drive shaft 20 and the fourth support frame 26 is the same as the connection method between the first drive shaft 19 and the third support frame 25.

[0080] The third support frame 25 and the fourth support frame 26 can provide support for the first drive shaft 19 and the second drive shaft 20, preventing the first drive shaft 19 and the second drive shaft 20 from falling off due to lack of support and causing failure of the pitch adjustment assembly.

[0081] In one embodiment, the first bearing seat 9 and the second bearing seat 10 are slidably connected to the first support frame 7, and the third bearing seat 11 and the fourth bearing seat 12 are slidably connected to the second support frame 8.

[0082] Specifically, the first support frame 7 may be provided with a sliding groove that matches the shape of the first bearing seat 9 and the second bearing seat 10, so that the first bearing seat 9 and the second bearing seat 10 can slide in the sliding groove; or the first bearing seat 9 and the second bearing seat 10 may be provided with a slot that cooperates with the slide rail for sliding; the cooperation method between the third bearing seat 11 and the fourth bearing seat 12 and the second support frame 8 is the same as the cooperation method between the first bearing seat 9 and the second bearing seat 10 and the first support frame 7.

[0083] The first bearing housing 9, the second bearing housing 10, the third bearing housing 11, and the fourth bearing housing 12 are slidably connected to the first support frame 7 and the second support frame 8 via slide rails or sliding grooves. This reduces the moving resistance of the bearing housing during the adjustment process and provides a limiting function in the direction perpendicular to the moving direction of the bearing housing, thereby reducing the probability of failure.

[0086] This setting provides power for the first roller 1 and the second roller 2 respectively, without having to make one of the rollers rotate under the drive of the other roller, so that the distance adjustment between the two rollers is limited, and the rotation speed and direction of the two rollers can also be set separately, so that the material pressing of the rollers can adapt to the needs of production.

[0087] As an implementation, the first roller 1 and the second roller 2 are mirror rollers, and the rollers are hollow. The setting of the mirror roller can improve the surface quality and brightness of the material pressing, reduce the friction force, reduce the raw material residue, and reduce the cleaning cost; the hollow of the first roller 1 and the second roller 2 can set a heating pipe in the first roller 1 and the second roller 2 to realize the heating of the first roller 1 and the second roller 2.

[0091] The first fixed ring is fixedly connected with the first sliding shaft 5 and can rotate synchronously with the first sliding shaft 5; the first sliding ring is connected with the power supply and cannot rotate, and at the same time, the first sliding ring transmits power to the first fixed ring, realizes power-on of the heating pipe, and avoids winding of the power supply line caused by rotation of the first roller 1; the second fixed ring and the second sliding ring have the same action mode as the first fixed ring and the first sliding ring.

[0092] As an embodiment, the material blocking plates 33 are arranged on both sides above the first roller 1 and the second roller 2, and the material receiving boxes 35 are arranged below the first roller 1 and the second roller 2, which are used to receive and recycle the dropped raw materials.

[0093] When the materials are fed, the design of the material blocking plates 33 can make more materials be fed between the rollers without overflowing and reduce the probability of dropping of the materials below the rollers, improve the cleanliness of the materials, and further improve the quality of the products; in addition, the design of the material receiving boxes 35 can also receive the dropped materials, and at the same time, the dropping of the raw materials in the production process is avoided, so that the design of the material blocking plates 33 and the material receiving boxes 35 can only avoid waste of the materials, but also can ensure the cleanliness of the materials and improve the quality of the products, which is suitable for products with higher quality requirements.

[0094] Specifically, the two material blocking plates 33 are linked with the first support frame 7 and the second support frame 8 through material blocking telescopic rods respectively, the positions of the material blocking plates 33 can be manually adjusted, and the distance between the two material blocking plates 33 can be set.
