Description

Technical Field

[0001] This utility model relates to the technical field of extruders, and specifically to a linkage baffle protection structure for an extruder. Background Technology

[0002] In existing extrusion presses, the barrel assembly typically needs to tilt between the feeding and extrusion positions. However, this tilting operation often exposes openings in the machine body, allowing wastewater and waste materials generated during the mold opening process to easily enter the machine body, causing contamination and damage. For example, Chinese Patent Publication No. CN117047074A discloses a composite molding equipment and its composite molding process. This equipment includes an extrusion mechanism oscillating on the machine body and a material tube connected to an extrusion structure. An opening is provided on the machine body corresponding to the oscillating position of the extrusion mechanism. When the material tube oscillates with the extrusion mechanism to the outside of the fixed mold platen, the opening on the machine body is open and connected to the outside air. This allows wastewater and waste materials generated during mold opening to easily fall into the machine body through the opening. Utility Model Content

[0003] This utility model proposes a linkage baffle protection structure for an extruder. By setting a sliding baffle on the machine body, the baffle is linked and connected to the barrel assembly, so that the baffle can slide on the machine body as the barrel assembly tilts. This allows the baffle to always cover the installation clearance slot of the machine body during the tilting of the barrel assembly, preventing wastewater and waste materials outside the machine body or wastewater and waste materials generated during mold opening from entering the machine body, effectively protecting the internal structure of the machine body.

[0004] A linkage baffle protection structure for an extruder designed for this purpose includes a baffle that is connected to the barrel assembly. The baffle is slidably mounted on the machine body. The barrel assembly is tilted on the machine body and tilted to the feeding position or the extrusion position. The machine body is provided with an installation clearance opening groove corresponding to the barrel assembly. During the process of the baffle following the barrel assembly from the extrusion position to the feeding position, the baffle slides on the machine body along the direction of covering the installation clearance opening groove.

[0005] The material cylinder assembly is equipped with a connecting plate. One end of the connecting plate is connected to the material cylinder assembly, and the other end of the connecting plate is connected to the baffle. During the tilting process of the material cylinder assembly, the connecting plate drives the baffle to slide on the machine body.

[0006] The barrel assembly includes a connecting column and a connecting flange. The connecting plate includes a transverse connecting plate, which is connected to the connecting column. The transverse connecting plate is provided with an air-avoiding ring groove corresponding to the connecting flange.

[0007] The connecting plate includes a horizontal connecting plate connected to the barrel assembly, and a vertical connecting plate extending downward below the horizontal connecting plate;

[0008] The vertical connecting plate includes a side block, and the baffle is provided with a positioning slot corresponding to the side block. A positioning connecting block is provided on the positioning slot. The baffle and the vertical connecting plate of the connecting plate are assembled, and the side block is positioned on the positioning slot and rotatably connected with the positioning connecting block.

[0009] The barrel assembly tilts, and the side block of the connecting plate rotates to limit the rotation on the positioning slot.

[0010] The machine body is provided with a fixed plate that is slidably connected to the baffle, and the fixed plate is provided with an opening groove corresponding to the material cylinder assembly for communicating installation and clearance opening groove.

[0011] The baffle is provided with an inclined plate. As the baffle follows the material cylinder assembly from the extrusion position to the feeding position, the baffle and its inclined plate block the opening slot.

[0012] The fixed plate has an upper limit block on its side and a lower limit block on the machine body below the upper limit block. A limiting groove is formed between the upper limit block and the lower limit block. The side of the baffle slides in cooperation with the limiting groove. The baffle tilts with the material cylinder assembly and slides on the limiting groove.

[0013] The side of the baffle is provided with a sliding engagement component that slides in conjunction with the limiting slide groove, and the sliding engagement component is embedded in the limiting slide groove;

[0014] The side of the baffle is provided with a side plate extending downwards from the baffle. A sliding fitting is provided on the inner side of the side plate, and a fixing member is provided on the outer side of the side plate. Fasteners are provided between the fixing member, the side plate and the sliding fitting, and the fixing member, the side plate and the sliding fitting are connected to each other by fasteners.

[0015] The sliding engagement component is a slider or a rotating roller.

[0016] The bottom of the baffle is provided with a reinforcing plate to increase the mechanical strength of the baffle.

[0017] The machine body includes a frame rotatably connected to the barrel assembly, and a drive cylinder for driving the barrel assembly to rotate is provided on the machine body.

[0018] The beneficial technical effects of this utility model are as follows:

[0019] By installing a sliding baffle on the machine body, which is linked to the barrel assembly, the baffle can slide on the machine body as the barrel assembly tilts. This ensures that the baffle always blocks the installation clearance opening slot of the machine body during the tilting process of the barrel assembly, preventing wastewater and waste materials from the outside of the machine body or generated during mold opening from entering the machine body. This effectively protects the internal structure of the machine body and solves the technical problem that wastewater and waste materials from the outside of the machine body can easily enter the machine body through the installation clearance opening slot during barrel rotation, thus contaminating the internal structure of the machine body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0031] See Figures 1-10A linkage baffle protection structure for an extruder includes a baffle 1 that is connected to a barrel assembly 2. The baffle 1 is slidably disposed on a machine body 3. The barrel assembly 2 is tilted on the machine body 3 and tilted to a feeding position 4 or an extrusion position 5. The machine body 3 is provided with an installation clearance opening groove 6 corresponding to the barrel assembly 2. During the process of the baffle 1 following the barrel assembly 2 from the extrusion position 5 to the feeding position 4, the baffle 1 slides on the machine body 3 along the direction of covering the installation clearance opening groove 6.

[0032] By setting baffle 1 to be linked with the material cylinder assembly 2, baffle 1 can block the installation and avoidance slot 6 during the process of the material cylinder assembly 2 tilting from the extrusion position 5 to the feeding position 4, effectively preventing wastewater, waste materials, etc. from entering the machine body 3 through the opening slot 6, thus improving the cleanliness and service life of the equipment; and baffle 1 resets during the process of the material cylinder assembly 2 tilting from the feeding position 4 to the extrusion position 5.

[0033] The material cylinder assembly 2 is provided with a connecting plate 7. One end of the connecting plate 7 is connected to the material cylinder assembly 2, and the other end of the connecting plate 7 is connected to the baffle 1. During the tilting process of the material cylinder assembly 2, the connecting plate 7 drives the baffle 1 to slide on the machine body 3.

[0034] By setting the connecting plate 7, the tilting motion of the barrel assembly 2 can be directly transmitted to the baffle 1, so that the baffle 1 can move with the barrel assembly 2, ensuring that the baffle 1 can block the installation avoidance slot 6.

[0035] The barrel assembly 2 includes a connecting column 8 and a connecting flange 9. The connecting plate 7 includes a transverse connecting plate 10, which is connected to the connecting column 8. The transverse connecting plate 10 is provided with an air-avoiding ring groove 11 corresponding to the connecting flange 9.

[0036] By providing a transverse connecting plate 10 connected to the connecting column 8 on the connecting plate 7, and providing an anti-cavity annular groove 11 on the transverse connecting plate 10, the connecting plate 7 can avoid interference with the connecting flange 9 when the barrel assembly 2 is connected.

[0037] In this embodiment, the connecting column 8 is fixedly connected to the transverse connecting plate 10 by screws.

[0038] The connecting plate 7 includes a horizontal connecting plate 10 connected to the barrel assembly 2, and a vertical connecting plate 12 extending downward below the horizontal connecting plate 10;

[0039] The vertical connecting plate 12 includes a side block 13. The baffle 1 is provided with a positioning slot 14 corresponding to the side block 13. A positioning connecting block 15 is provided on the positioning slot 14. The baffle 1 is assembled with the vertical connecting plate 12 of the connecting plate 7. The side block 13 is positioned on the positioning slot 14 and rotatably connected to the positioning connecting block 15.

[0040] When the barrel assembly 2 tilts, the side block 13 of the connecting plate 7 is limited to rotating on the positioning slot 14.

[0041] By setting the vertical connecting plate 12 and the positioning slot 14, the connecting plate 7 can tilt with the material cylinder assembly 2, while the baffle 1 is always limited to sliding on the machine body 3, thus satisfying the linkage connection between the baffle 1 and the material cylinder assembly 2. Through an adapter, the baffle 1 will not tilt or swing on the machine body with the material cylinder assembly 2.

[0042] In this embodiment, the side block 13 is provided with a long slot, and the positioning connecting block 15 is provided with a shaft hole. The slot and the shaft hole are connected to the connecting shaft through a gasket, so that the connecting plate 7 tilts and pulls the baffle 1 to slide with the material cylinder assembly 2.

[0043] The machine body 3 is provided with a fixed plate 16 that is slidably connected to the baffle 1. The fixed plate 16 is provided with an opening groove 17 corresponding to the material cylinder assembly 2, which is connected to the installation clearance opening groove 6. During the tilting process, the fixed plate 16 and the material cylinder assembly 2 can avoid interference.

[0044] The baffle 1 is provided with an inclined plate 27. During the process of the baffle 1 following the material cylinder assembly 2 from the extrusion position 5 to the feeding position 4, the baffle 1 and its inclined plate 27 block the opening slot 17 to prevent wastewater and waste materials outside the machine body 3 or wastewater and waste materials generated during mold opening from entering the machine body 3. This effectively protects the internal structure of the machine body 3 and solves the technical problem that wastewater and waste materials outside the machine body can easily enter the internal structure of the machine body 3 through the installation avoidance opening slot 6, opening slot 17, etc. during the rotation of the material cylinder assembly 2, thus contaminating the internal structure of the machine body 3.

[0045] The fixed plate 16 is provided with an upper limit block 18 on its side, and a lower limit block 20 is provided on the machine body 3 below the upper limit block 18. A limiting groove 19 is formed between the upper limit block 18 and the lower limit block 20. The side of the baffle 1 is slidably engaged with the limiting groove 19. The baffle 1 tilts with the material cylinder assembly 2 and the baffle 1 slides on the limiting groove 19.

[0046] By setting the limiting groove 19 formed by the upper limit block 18 and the lower limit block 20, the baffle 1 can be precisely limited during the sliding process, preventing the baffle 1 from shifting or getting stuck. The upper and lower limits of the baffle 1 are set on the limiting groove 19.

[0047] In this embodiment, one end of the fixing plate 16 is bent upward to form a fixing side plate, and one end of the fixing side plate extends laterally to form an upper limit block 18. The body 3 is provided with a first support plate for supporting the fixing plate 16, and the body 3 is provided with a second support plate for supporting the lower limit block 20.

[0048] The side of the baffle 1 is provided with a sliding engagement part 21 that slides with the limiting slide groove 19. The sliding engagement part 21 is embedded in the limiting slide groove 19.

[0049] The side of the baffle 1 is provided with a side plate 22 extending downward from the baffle 1. A sliding fitting 21 is provided on the inner side of the side plate 22. A fixing member 23 is provided on the outer side of the side plate 22. Fasteners are provided between the fixing member 23, the side plate 22 and the sliding fitting 21. The fixing member 23, the side plate 22 and the sliding fitting 21 are connected to each other by fasteners.

[0050] In this embodiment, the fastener is a screw.

[0051] The sliding engagement component 21 is a slider or a rotating roller.

[0052] By providing a slider or rotating roller in the sliding mating part 21, the baffle 1 can slide more smoothly, reducing friction and noise generated during equipment operation.

[0053] The bottom of the baffle 1 is provided with a reinforcing plate 24 to increase the mechanical strength of the baffle 1. By providing the reinforcing plate 24 at the bottom of the baffle 1, the mechanical strength of the baffle 1 is significantly improved, it can withstand greater external forces, prevent the baffle 1 from deforming or being damaged during sliding, and effectively improve the durability of the baffle 1.

[0054] The machine body 3 includes a frame 25 rotatably connected to the barrel assembly 2, and the machine body 3 is provided with a drive cylinder for driving the barrel assembly 2 to rotate.

[0055] In this embodiment, the frame 25 includes connecting and fixing brackets 26 arranged opposite to each other on the left and right sides, and the barrel assembly 2 is provided with a rotating shaft that is rotatably connected to the connecting and fixing brackets 26. The structure of the barrel assembly 2 is detailed in Chinese Patent Publication No. CN117047074A. The barrel assembly 2 in this solution is equivalent to the extrusion assembly and material tube structure disclosed in that patent, and the specific structure of the barrel assembly 2 will not be described in detail here.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
