The pushing block 46 is movably arranged on the slide rail 42 and can slide along the slide rail 42 in the X-axis direction under the drive of the servo motor 44 . In this embodiment, the pushing block 46 slides on the slide rail 42 by means of a ball screw. Of course, in other embodiments, a driving method such as an air cylinder may also be used. In the initial position, the ejector block 46 is located at one end of the mandrel. When the pushing block 46 slides along the slide rail 42 under the driving of the servo motor 44 , the pushing block 46 can exert force on one end of the mandrel, thereby gradually pushing the mandrel into the extruder 10 . In this embodiment, the pushing mechanism 40 further includes a second bearing block 48 . The second carrier block 48 is similar in shape to the first carrier block 32 , but is fixed to the ejector block 46 . When the mandrel enters the bearing mechanism 30, one end of the mandrel is supported by the first bearing block 32, and the other end of the mandrel is supported by the second bearing block 48, thereby ensuring the stability of the support. Of course, if the length of the first bearing block 32 is sufficient, the second bearing block 48 can also be omitted.

Please refer to FIG. 6 and FIG. 8 at the same time, the pre-compression mechanism 50 includes a support plate 52 fixedly disposed on the frame 24 and a slider 54 movably disposed on the support plate 52 . The sliding block 54 is movably connected to the support plate 52 through a mechanism such as an air cylinder or a screw rod, so that the sliding block 54 can slide back and forth in the Z-axis direction shown in the figure. The end of the slider 54 is provided with two opposing pressing wheels 56 . When the mandrel enters the positioning groove 322 of the first bearing block 32, the slider 54 can move downward, so that the two pressing wheels 56 can press the mandrel located in the positioning groove 322, so that the mandrel is more stably positioned in the positioning groove 322 sliding inside. When the mandrel leaves the positioning slot 322 , the slider 54 can be reset upwards, thereby allowing the next mandrel to enter the positioning slot 322 .

Referring to FIG. 9 , the feeding device 60 includes a feeding frame 62 for receiving and moving the mandrel 70 wrapped with the glue layer output from the extruder. A plurality of guide wheels 64 arranged in a straight line are arranged on the material receiving frame 62 . The guide rollers 64 correspond to the outlet 16 of the extruder 10 , so that the mandrel 70 wrapped with glue layer from the extruder 10 can slide on the plurality of guide rollers 64 and enter the unloading area. The guide wheel 64 can be powered by external power, so as to facilitate the faster movement of the mandrel 70 wrapped with the glue layer.

In order to further control the automation of the above components, in this embodiment, the extrusion molding apparatus 100 further includes a plurality of sensors and controllers 90 .

Referring again to FIGS. 3 and 6 , the plurality of sensors include a first metal sensor 82 and a second metal sensor 84 disposed on the carrier mechanism 30 . Specifically, the first metal sensor 82 and the second metal sensor 84 are respectively disposed at both ends of the first bearing block 32 , and the first metal sensor 82 is located between the first bearing block 32 and the extruder 10 . The first metal sensor 82 and the second metal sensor 84 can sense whether there is a mandrel in the vicinity of its position, and transmit a detection signal back to the controller 90 . When the first metal sensor 82 cannot sense the existence of the mandrel, it indicates that the mandrel has left the carrying mechanism 30 and entered the extruder 10 completely. When the second metal sensor 84 senses the existence of the mandrel, it indicates that the mandrel has been positioned on the carrier mechanism 30, and the subsequent pushing step can be performed.

Referring to FIG. 9 , the plurality of sensors further include a first position sensor 86 and a second position sensor 88 disposed on the feeding frame 62 . The first position sensor 86 and the second position sensor 88 are arranged on the movement track of the mandrel 70 wrapped with the adhesive layer, which can detect whether there is a mandrel 70 wrapped with the adhesive layer passing through the position of the sensor, and transmit the detection signal back to the controller 90. The specific positions of the first position sensor 86 and the second position sensor 88 on the splice rack 62 can be determined according to the length of the mandrel 70 wrapped with the glue layer. For example, the distance between the first position sensor 86 and the outlet 16 of the extruder 10 may be exactly equal to the length of the mandrel 70 wrapped with the glue layer. Therefore, when the first position sensor 86 senses that there is a mandrel 70 wrapped with the glue layer When passing, it indicates that the mandrel 70 wrapped with the adhesive layer has just left the extruder 10, thus indicating that the wrapping process of the mandrel has ended, and the pushing mechanism 40 can stop pushing the mandrel and return to the starting position. When the second position sensor 88 located behind the first position sensor 86 senses the passage of the mandrel 70 wrapped with the adhesive layer, it indicates that the mandrel 70 wrapped with the adhesive layer has completely left the extruder 10, so that the next step can be carried out. Handling of a mandrel. For example, the push mechanism 40 now pushes the next mandrel into the extruder 10 from the starting position. The introduction of the second position sensor 88 can prevent the previous mandrel from being pushed out of the extruder 10 before being pushed into the next mandrel, which may cause the risk of jamming or short mandrel. The distance between the first position sensor 86 and the second position sensor 88 can be determined empirically, for example, it can be about 10 cm. In this embodiment, the first position sensor 86 and the second position sensor 88 may be infrared sensors. It can be understood that the first position sensor 86 and the second position sensor 88 can also be other sensors capable of sensing the passing of objects.

Referring to FIG. 7 , the plurality of sensors further include a pressure sensor 89 for detecting the thrust of the ejector block 46 . The pressure sensor 89 is arranged on the pushing block 46 and is opposite to the second bearing block 48 . When the pressure sensor 89 detects that the thrust of the pushing block 46 exceeds the set threshold, it indicates that an abnormal situation such as a stuck shaft occurs, and the pressure signal can be sent to the controller 90 at this time, so as to carry out subsequent abnormal processing operations. For example, the controller 90 is used to control the pushing mechanism 40 and the extruder 10 to stop working, so as to avoid the risk of shaft breakage and the like.

As shown in FIG. 3 , the controller 90 is arranged on the frame 24 for controlling the operation of the entire extrusion molding equipment 100 . The controller 90 can communicate with the ejector mechanism 36 , the rotary stopper mechanism 38 , the pusher mechanism 40 , the pre-compression mechanism 50 , the extruder 10 , and a plurality of sensors 82 - 89 through connecting devices such as cables. The controller 90 may also include a display panel for displaying the operating parameters of each device, and these parameters may be manually adjusted. In this embodiment, the controller 90 is a single-chip microcomputer. It can be understood that the controller 90 can also be other computers with control functions.

The working process of the extrusion molding apparatus 100 is described in detail below.

First, adjust the position of the frame 24 in the horizontal Y-axis direction through the linear guide 222, and adjust the height of the first bearing block 32 through the movable support rod 324, so that the positioning groove 322 of the first bearing block 32 is connected to the entrance of the extruder 10. 14 Alignment. After the adjustment is completed, the position of the frame 24 is locked by the quick positioning mechanism 26 . Since the interior of the extruder 10 needs to be cleaned and repaired after a long period of production, the feeding device 20 and the extruder 10 need to be re-aligned before each production.

Next, the controller 90 controls the ejection mechanism 36 to eject the first mandrel from the silo to the material guide inclined surface 34, the mandrel will roll on the material guide inclined surface 34 under the action of gravity, and is blocked by the rotation The feeding mechanism 38 is blocked. After the ejection mechanism 36 returns to its original position, the controller 90 controls the motor 386 to rotate, thereby driving the plurality of stopper claws 384 of the rotating stopper mechanism 38 to rotate so that their ends are separated from the material guide slope 34, thereby allowing the mandrel to enter the bearing mechanism. 30.

When the first metal sensor 82 and the second metal sensor 84 simultaneously detect that the mandrel enters the bearing mechanism 30 , the controller 90 controls the slider 54 of the pre-compression mechanism 50 to move downward, and the mandrel is pre-compressed and positioned by the pressing wheel 56 . After that, the controller 90 controls the servo motor 44 of the pushing mechanism 40 to drive the pushing block 46 to start to push the mandrel to move toward the inlet 14 of the extruder 10 . The controller 90 controls the extruder 10 to wrap a layer of adhesive layer on the surface of the mandrel, and after the mandrel 70 wrapped with the adhesive layer is formed, it enters the feeding frame 62 of the unloading device 60 from the outlet 16 of the extruder 10, And slide on a plurality of guide wheels 64, and finally enter the unloading area.

When the first metal sensor 82 cannot sense the existence of the mandrel, it indicates that the mandrel has left the carrying mechanism 30 and entered the extruder 10 completely. When the first position sensor 86 senses that the mandrel 70 wrapped with the adhesive layer has passed by, it indicates that the mandrel 70 wrapped with the adhesive layer has just left the extruder 10, thus indicating that the wrapping process of the mandrel has ended, and push The feeding mechanism 40 can stop pushing the mandrel and return to the starting position. Under the action of the extruder 10 , the mandrel 70 wrapped with the glue layer will continue to slide on the plurality of guide wheels 64 of the feeding frame 62 . When the sensor 88 at the second position senses the passage of the mandrel 70 wrapped with the adhesive layer, it indicates that the mandrel 70 wrapped with the adhesive layer has completely left the extruder 10 . If neither the first metal sensor 82 nor the second metal sensor 84 senses the existence of the mandrel at this time, the controller 90 can control the rotation stopper mechanism 38 to rotate and release another mandrel into the carrying mechanism 30, thereby starting the down-flow A round of push shafts.

During the whole pushing process, the controller 90 monitors the pushing force of the pushing block 46 through the pressure sensor 89 in the whole process. When the pressure sensor 89 detects that the thrust of the pushing block 46 exceeds the set threshold, it means that there is an abnormal situation such as a stuck shaft. At this time, the controller 90 can immediately control the pushing mechanism 40 and the extruder 10 to stop working to avoid Risk of shaft breakage, etc.

As can be seen from the above, the extrusion molding equipment 100 of this embodiment can realize fully automatic feeding, extrusion and unloading without manual intervention by the operator, and has a high degree of automation, which improves production efficiency and avoids danger.
