Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the claims that follow.

In the correlation technique, the consumptive material dress of most printers is intraductal in order to supply with the consumptive material to the extruder at the teflon, and the feed inlet and the discharge gate of these extruders all are on same vertical line, need arrange the space of big section in the vertical direction of extruder feed inlet and place consumptive material and teflon pipe, cause the ascending space waste of extruder vertical side, and then influence the size of a dimension of printer.

To solve the above problem, referring to fig. 1 to 3, an embodiment of the present application provides an extruder 1, and the extruder 1 is disposed on a printer (not shown). The extruder 1 comprises at least one pressing component 2, and each pressing component 2 comprises a driving wheel 21 and at least one pressing wheel 22 so as to extrude the consumable.

The drive wheel 21 is used for coordinating with pinch roller 22 and extrudees the consumptive material, and drive wheel 21 can rotate around its axis of rotation, makes the consumptive material that is extruded can transport forward along with the rotation of drive wheel 21 to guarantee that the not processed part of consumptive material can be continuous by drive wheel 21 and pinch roller 22 extrusion.

The pressing wheel 22 is used for being matched with the driving wheel 21 to extrude the consumable, the pressing wheel 22 is arranged on the periphery of the driving wheel 21 around the rotating axis direction of the driving wheel 21, and the feeding channel 3 is formed between the pressing wheel 22 and the driving wheel 21, so that the consumable can be continuously extruded in the feeding channel 3. Understandably, the pinch roller 22 can rotate, and in the process that the consumable is extruded by the rotation of the transmission wheel 21, the consumable can drive the pinch roller 22 to rotate, so that the friction between the pinch roller 22 and the consumable is changed into rolling friction by sliding friction, thereby reducing the friction between the consumable and the transmission wheel 21 and the pinch roller 22, and enabling the consumable to be more easily transported in the feeding channel 3.

In addition, please refer to fig. 3, the extruder 1 at least includes two pinch rollers 22, one pinch roller 22 is disposed near the feeding port, another pinch roller 22 is disposed near the discharging port, and the feeding channel 3 corresponding to the pinch roller 22 disposed near the feeding port extends along the first linear direction X, and the feeding channel 3 corresponding to the pinch roller 22 disposed near the discharging port extends along the second linear direction Y, wherein the first linear direction X intersects with the second linear direction Y, so that the feeding direction and the discharging direction of the consumable material change, avoid the extruder 1 to set the feeding port and the discharging port in the same direction, and further reduce the space waste of the extruder 1 in the direction. For example, the feeding port and the discharging port 2 of the extruder 1 can be prevented from being arranged in the same vertical direction, and the waste of space of the extruder 1 on the vertical line can be reduced. Simultaneously, above-mentioned scheme can effectively reduce the size of dimensions of printer complete machine, and the miniaturization of the printer of being convenient for, and make the printer more pleasing to the eye. It will be understood that the feed channel 3 corresponding to each press wheel 22 extends in a direction corresponding to the tangent of the drive wheel 21 at the location corresponding to that press wheel 22.

Specifically, the extruder 1 is used as follows: when the extruder 1 operates, the driving wheel 21 in the material pressing assembly 2 rotates around the rotation axis of the driving wheel, the consumable enters the feeding channel 3 corresponding to the feeding hole from the feeding hole and is jointly extruded by the driving wheel 21 and the pressing wheel 22 close to the feeding hole, and under the rotation of the driving wheel 21, the consumable can be driven to enter the feeding channel 3 corresponding to the discharging hole and is jointly extruded by the driving wheel 21 and the pressing wheel 22 close to the discharging hole, so that the processing of the consumable is completed. Because the feeding channel 3 that corresponds the feed inlet extends along first straight line direction X, and the feeding channel 3 that corresponds the discharge gate extends along second straight line direction Y, makes the consumptive material when passing through two feeding channels 3, and the relative direction of feed of the relative direction of discharge of consumptive material has taken place to change, and then avoids consumptive material direction of feed and direction of discharge to be same direction to it is extravagant in this ascending space of extruder 1 to reduce.
