DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Please refer to Figure 1 The utility model provides a kind of technical solutions: a kind of extrusion forming machine discharge structure of material can be prevented to be pulled, including: extruder 1 and forming die 3, one side of extruder 1 is connected with conveying channel 2, forming die 3 is installed at the top of conveying channel 2;

[0026] The inner wall of forming die 3 is installed with annular scraper 4, the top of annular scraper 4 is installed with connecting rod 5, one side of connecting rod 5 is inserted with telescopic block 6, movable spring 7 is connected between the recess of forming die 3 and telescopic block 6, the top of telescopic block 6 is connected with connecting block 8 that penetrates forming die 3, the inside of conveying channel 2 is installed with driving motor 9 by recess, the output end of driving motor 9 is connected with bidirectional screw rod 10 by shaft coupling, both ends of bidirectional screw rod 10 are all sleeved with screw sleeve 11, one side of screw sleeve 11 is connected with first movable block 12, one side of first movable block 12 is installed with cutting knife 13, cutting knife 13 is symmetrically installed with two groups about the center line of conveying channel 2.

[0027] In specific implementation, when the bottle blank needs to be taken out from the forming mold 3, the connecting block 8 can be pulled to make the connecting block 8 drive the telescopic block 6 to shrink into the groove of the forming mold 3 and press the movable spring 7, at this time, the telescopic block 6 does not limit the connecting rod 5, then the connecting rod 5 can be pulled upward, the bottom of the connecting rod 5 is provided with the annular scraper 4, so the connecting rod 5 drives the annular scraper 4 to move upward along the forming mold 3, and the annular scraper 4 can scrape off the material adhered to the inner wall of the forming mold 3 when moving upward, thereby avoiding the phenomenon of material pulling when taking out the material due to the material adhered to the forming mold 3.

[0028] At the same time, the driving motor 9 is started, the driving motor 9 drives the bidirectional screw rod 10 to rotate through the shaft coupling, the bidirectional screw rod 10 drives the screw sleeves 11 connected at both ends to move in opposite directions, when the two groups of screw sleeves 11 move close to each other, the first movable block 12 drives the cutting knives 13 on one side to move close to each other, thereby separating the material in the forming mold 3 from the material in the conveying channel 2, avoiding the phenomenon of mutual adhesion of the material adhered to the bottom of the bottle blank and the material in the conveying channel 2 when taking out the material.

[0029] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , in use, the telescopic block 6 can be pulled into the interior of the forming mold 3, so that the telescopic block 6 does not limit the connecting rod 5, then the annular scraper 4 is pulled upward through the connecting rod 5, the annular scraper 4 can separate the material from the forming mold 3 when being pulled, thereby avoiding the phenomenon of pulling the material when taking out the material due to the adhesion of the material to the forming mold 3, and cooperating with the cutting knives 13 to separate the material in the forming mold 3 from the material in the conveying channel 2, avoiding the adhesion of the material.

[0030] The top of the forming mold 3 is provided with the fixed block 14, the top of the fixed block 14 is inserted with the plug block 15 through the groove, the interior of the plug block 15 is connected with the two groups of rotating blocks 16 through the rotating shaft, the two groups of rotating blocks 16 are connected with the telescopic spring 17, the top of the rotating block 16 is sleeved with the second movable block 18, one side of the second movable block 18 is connected with the pull rod 19, the inner wall of the fixed block 14 is provided with the protruding block 20, and the plug block 15 is installed on both sides of the forming mold 3.

[0031] In specific implementation, when the discharge structure of the extrusion molding machine capable of preventing material pulling needs to replace the molding mold 3, only the pull rod 19 needs to be pulled upward, and the movement of the pull rod 19 drives the second movable block 18 to move upward. Since the second movable block 18 is sleeved between the two groups of rotating blocks 16, and the two groups of rotating blocks 16 are connected in the groove of the plug-in block 15 through the rotating shaft, the movement of the second movable block 18 will extrude the rotating blocks 16 through the inner wall of the groove, so that one end of the rotating blocks 16 close to the second movable block 18 rotates close to each other. Since the two groups of rotating blocks 16 share a group of rotating shafts, the other end of the rotating blocks 16 will also rotate close to each other. When the rotating blocks 16 rotate close to each other, they will move out from one side of the protruding block 20, so that the protruding block 20 does not limit the rotating blocks 16, and then the plug-in block 15 can be pulled out from the top of the fixed block 14, so as to conveniently and quickly separate the molding mold 3 from the conveying channel 2, and facilitate the replacement of the molding mold 3.

[0032] Conversely, only the plug-in block 15 needs to be inserted into the inside of the fixed block 14. Since one end of the rotating block 16 is a beveled structure, the rotating block 16 will rotate when it is extruded by the protruding block 20 during the process of inserting the plug-in block 15. The two groups of rotating blocks 16 will extrude the expansion spring 17 in the middle when rotating. When the groove on one side of the rotating block 16 is aligned with the protruding block 20, the expansion spring 17 will reset and drive the rotating block 16 to rotate in the opposite direction, so that the protruding block 20 is clamped on one side of the rotating block 16. Through the cooperation of the protruding block 20 and the rotating block 16, the plug-in block 15 can be fixed with the fixed block 14, so as to conveniently and quickly connect and fix the molding mold 3 with the conveying channel 2.

[0033] As can be seen from Figure 1 , Figure 5 and Figure 7 , in use, the pull rod 19 can be pulled according to the use requirements, so that the pull rod 19 drives the rotating block 16 to rotate through the second movable block 18. The rotating block 16 will be separated from the protruding block 20 when rotating. At this time, the plug-in block 15 can be disassembled from the top of the fixed block 14, so as to conveniently replace and disassemble the molding mold 3.

[0034] In summary: the discharge structure of the extrusion molding machine capable of preventing material pulling can start the extruder 1 when in use, and the plastic bottle production raw materials can be poured into the extruder 1 through the feeding port. The extruder 1 will convey the raw materials heated and melted through the conveying channel 2 to the molding mold 3, and then cool and form the raw materials through the molding mold 3, so as to obtain the molded bottle embryo, which is convenient for subsequent bottle blowing work. This is the use feature of the discharge structure of the extrusion molding machine capable of preventing material pulling.
