According to one aspect of the embodiment of the present invention, as shown in Figure 1, this embodiment needs to be used in conjunction with the upper squeeze roller to realize the extrusion and molding of continuous materials. In this embodiment, the upper squeeze roller is also one Two half-test adjustable rollers, which are divided into a first half-roller and a second half-roller, the first half-roller and the second half-roller are both symmetrical in the center of rotation, and the first and second half-rollers are both installed On a through shaft, the through shaft is installed on the frame (6) and can move up and down relative to the frame (6) to realize the use of the first half roller and the second half roller in conjunction with the combined roller of this embodiment for continuous materials Perform extrusion molding.

According to Fig. 1 to Fig. 4, the specific work flow of the embodiment of the present invention is as follows. First, the specific work flow is introduced by taking the increase of product specifications as an example. The production line receives the instruction and needs to change the specifications of the produced products, and then the production line stops, the upper squeeze roller starts to move upward to leave the continuous material being squeezed, when the upper squeeze roller is far away from the continuous material, the turbine of the telescopic device (5) slows down The turbine (51) inside the worm gear reducer starts to rotate, and the internal thread (511) starts to rotate synchronously. Because the internal thread (511) is on the outer sliding surface (431) on the side of the outer casing (43) The external thread (41) is provided for mutual cooperation, and the turbine reducer is fixed on the frame (6). The outer sliding surface (431) of the outer casing (43) and the inner sliding surface (61) of the frame (6) can be in clearance fit with each other and They are connected by sliding keys, so the turbine (51) is directly driven to cause the outer casing (43) to move to the outside relative to the frame (6). However, because the casing (43) is provided with a rotating sleeve (42) inside, and the movement of the rotating sleeve (42) and the casing (43) in the axial direction are synchronized, the outer movement of the casing (43) is directly Drives the rotating sleeve (42) to move to the outside relative to the frame (6) in synchronization with it, and the adjustable roller (2) can rotate freely relative to the rotating sleeve (42) under the action of the bearing, but at the same time it can move with the rotating sleeve (42) Synchronous axial movement. Therefore, the outer casing (43) can drive the adjustable roller (2) to move outward along the central axis (3) in the axial direction to realize the shape of the roller surface formed by the adjustable working surface (21) and the basic working surface (11). The size of the squeeze roller becomes larger. When the shape and specifications of the combined roller are adjusted, the upper squeeze roller realizes the coordinate adjustment of the first half roller and the second half roller relative to the combined roller simultaneously, and starts to move downward to continue to apply pressure to the continuous material. The upper squeeze roller and The combined use of combined rollers produces new specifications and shapes for continuous materials.

When the product specification needs to be reduced, the production line receives an instruction to change the specifications of the produced product, and then the production line stops, and the upper squeeze roller starts to move upward to leave the continuous material being squeezed. When the upper squeeze roller is away from the continuous material for a certain distance, The turbine reducer of the telescopic device (5) starts to work, the turbine (51) inside the turbine reducer starts to rotate, and the internal thread (511) inside it starts to rotate synchronously. Also due to the internal thread (511) and the outer casing (43) One side of the outer sliding surface (431) is provided with external threads (41) to cooperate with each other, and the turbine reducer is fixed on the frame (6), and the outer sliding surface (431) of the outer casing (43) slides with the frame (6). The surfaces (61) can be in clearance fit with each other and are connected with each other by sliding keys, so the turbine (51) is directly driven so that the outer casing (43) moves inward relative to the frame (6). However, because the casing (43) is provided with a rotating sleeve (42) inside, and the movement of the rotating sleeve (42) and the casing (43) in the axial direction are synchronized, the outer movement of the casing (43) is directly Drives the rotating sleeve (42) to move inwardly relative to the frame (6) in synchronization with it, and the adjustable roller (2) can freely rotate relative to the rotating sleeve (42) under the action of the bearing, but at the same time it can also move with the rotating sleeve (42) Synchronous axial movement. Therefore, the outer casing (43) can drive the adjustable roller (2) to move inward along the central axis (3) in the axial direction to realize the shape of the roller surface formed by the adjustable working surface (21) and the basic working surface (11). The size of the squeeze roll becomes smaller. When the shape and specifications of the combined roller are adjusted, the upper squeeze roller realizes the coordinate adjustment of the first half roller and the second half roller relative to the combined roller simultaneously, and starts to move downward to continue to apply pressure to the continuous material. The upper squeeze roller and The combined use of combined rollers produces new specifications and shapes for continuous materials.

According to Figures 5 and 6, the specific working process of the embodiment of the present invention is as follows. The production line receives an instruction to change the specifications of the produced product, and then the production line stops, and the upper squeeze roller starts to move upward to leave the continuous material being squeezed. After the upper squeeze roller is away from the continuous material for a certain distance, the turbine reducers of the telescopic devices (5) on both sides of the frame (6) start to work synchronously, the turbine (51) inside the turbine reducer starts to rotate synchronously, and the internal thread (511) Start to rotate synchronously, also because the internal thread (511) and the outer sliding surface (431) on one side of the outer casing (43) are provided with an external thread (41) to cooperate with each other, and the turbine reducer is fixed to the frame (6) Above, the outer sliding surface (431) of the outer casing (43) and the inner sliding surface (61) of the frame (6) can be in clearance fit with each other and are connected with each other by sliding keys, so the turbine (51) directly drives the two sides on both sides The two outer jackets (43) realize synchronous telescopic movement relative to the frame (6). However, because the two outer sleeves (43) are provided with a rotating sleeve (42) inside, and the rotation sleeve (42) and the outer sleeve (43) move synchronously in the axial direction, the two outer sleeves (43) The telescopic movement directly drives the two rotating sleeves (42) to achieve telescopic movement relative to the frame (6) synchronously with them, and the adjustable roller (2) can rotate freely relative to the rotating sleeve (42) under the action of the bearing, but At the same time, the axial movement can be synchronized with the rotating sleeve (42). Therefore, the two jackets (43) can drive the two adjustable rollers (2) to move relative to each other in the axial direction along the central axis (3), so as to realize the roller formed by the adjustable working surface (21) and the basic working surface (11). The surface shape changes the specifications of the squeeze roller relative to the overall symmetry surface. When the shape and specifications of the combined roller are adjusted, the upper squeeze roller realizes the coordinate adjustment of the first half roller and the second half roller relative to the combined roller simultaneously, and starts to move downward to continue to apply pressure to the continuous material. The upper squeeze roller and The combined use of combined rollers produces new specifications and shapes for continuous materials.
