[0027] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0028] ​​Secondly, the "one embodiment" or "embodiment" referred to herein means that a specific feature, structure, or characteristic described can be included in at least one implementation of the present application. The "in one embodiment" appearing in various places in the specification does not all refer to the same embodiment, nor does it necessarily refer to a separate or alternative embodiment.

[0029] Embodiment 1

[0030] With reference to Figures 2 to 7 For the first embodiment of the present application, the embodiment provides an extruder head module discharge anti-blocking device. The extruder head module discharge anti-blocking device comprises a scraping assembly 200, a collecting assembly 300 and a main body assembly 100. When there is plastic melt attached to the outlet, the three assemblies can cooperate to scrape it off.

[0031] The scraping assembly 200 comprises a scraping piece 201, which comprises a scraper 201a, a moving rod 201b, a moving frame 201c and a driving rod 201d. The moving rod 201b is hingedly connected to one side of the scraper 201a. The moving frame 201c is fixed to the top of the moving rod 201b. The driving rod 201d is hingedly connected to the top of the moving frame 201c.

[0032] When there is plastic melt attached to the outer circle of the discharge port 101, the driving rod 201d is flipped. At this time, the driving rod 201d can drive the moving frame 201c to move. The movement of the moving frame 201c drives the moving rod 201b to move. The movement of the moving rod 201b drives the scraper 201a to move on one side of the support frame 202c. Thus, the plastic melt remaining on the outer circle of the discharge port 101 can be scraped off.

[0033] The collecting assembly 300 is arranged below the scraping piece 201 and comprises a collecting piece 301, which comprises a collecting frame 301a, a closing plate 301b and a first torsional spring 301c. The collecting frame 301a is arranged below the scraper 201a. The closing plate 301b is hingedly connected to one side of the collecting frame 301a. One end of the first torsional spring 301c is fixed to the inner wall of the collecting frame 301a, and the other end is connected to one side of the closing plate 301b.

[0034] Before scraping the plastic melt, the closing plate 301b is opened. When the closing plate 301b is opened, it is inclined. At this time, the scraped plastic melt is transmitted to the collecting frame 301a through the guidance of the closing plate 301b. When the closing plate 301b is opened, a torsional force can be applied to the first torsional spring 301c. After collecting the plastic melt, the closing plate 301b can be closed by the rotating force of the first torsional spring 301c. Thus, the collecting frame 301a can be closed.

[0035] Embodiment 2

[0036] With reference to Figures 2 to 7For the second embodiment of the utility model, the embodiment is based on the previous embodiment.

[0037] Specifically, the scraping assembly 200 further comprises a support 202 arranged on the driving rod 201d, and a handle 202a is fixed to one end of the driving rod 201d.

[0038] The handle 202a is arranged to facilitate the user to move the driving rod 201d, so that the driving rod 201d can drive the scraper 201a to scrape the plastic melt.

[0039] Specifically, the driving rod 201d is provided at one end with a positioning plate 202b hinged to one end of the driving rod 201d, and the bottom of the positioning plate 202b is provided with a support frame 202c.

[0040] The positioning plate 202b is used to support the driving rod 201d to prevent the driving rod 201d from deviating, and the support frame 202c is used to support the positioning plate 202b to prevent the positioning plate 202b from deviating.

[0041] Specifically, the scraper 201a is provided at one side with a sliding block 202d, and the sliding block 202d is fixed at one side with a support bar 202e inserted into the support frame 202c, and the support frame 202c and the support bar 202e are movably connected.

[0042] The number of sliding blocks 202d is two, which are fixed to both sides of the scraper 201a, and the number of support bars 202e is two, which are both slidably connected to the support frame 202c. When the scraper 201a moves, the sliding block 202d can be moved, and the movement of the sliding block 202d can drive the support bar 202e to move, so that the support bar 202e can slide in the support frame 202c, thereby supporting the scraper 201a to prevent the scraper 201a from deviating when moving.

[0043] Specifically, the bottom of the support bar 202e is provided with a spring 202f fixed to the inner wall of the support frame 202c, and the spring 202f is provided with a positioning column 202g.

[0044] When the support bar 202e moves, an extruding force can be applied to the spring 202f. There are two springs 202f, both of which are fixed to the inner wall of the support frame 202c. A support hole corresponding to the positioning column 202g is provided on the support bar 202e. When the support bar 202e moves, it will move on the positioning column 202g. The setting of the positioning column 202g can support the spring 202f to prevent the spring 202f from deflecting when the spring 202f is squeezed. When the support bar 202e moves to drive the scraper 201a to scrape the plastic melt, the handle 202a is released, and the rebound force of the spring 202f can drive the support bar 202e to return to its original position, thereby driving the scraper 201a to return to its original position.

[0045] Specifically, the collecting assembly 300 further includes a moving part 302, which is arranged on the collecting frame 301a. The collecting frame 301a is fixed to the bottom of the supporting frame 202c, and a rocker 302a is fixed to one side of the closing plate 301b.

[0046] When the closing plate 301b needs to be opened, the rocker arm 302a is moved. When the rocker arm 302a moves, the closing plate 301b can be driven to move, thereby opening the closing plate 301b.

[0047] Specifically, a pulley 302b is provided at one end of the swing rod 302a, a connecting frame 302c is sleeved on the outside of the pulley 302b, the pulley 302b and the connecting frame 302c are hinged, and the connecting frame 302c is rotatably connected to one end of the swing rod 302a through a rotating shaft.

[0048] A sliding groove corresponding to the pulley 302b is provided on one side of the collection frame 301a. When the rocker arm 302a moves, the connecting frame 302c can be driven to move. When the connecting frame 302c moves, the pulley 302b can be driven to slide in the sliding groove. At this time, the rocker arm 302a can be supported to prevent the rocker arm 302a from deviating during movement.

[0049] Example 3

[0050] Reference Figures 1 to 7 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0051] Specifically, a limiting plate 302d is provided on one side of the collecting frame 301a, and a positioning frame 302e is provided on one side of the limiting plate 302d. The limiting plate 302d and the positioning frame 302e are hinged.

[0052] A limiting slot corresponding to the swing lever 302a is formed on one side of the limiting plate 302d, and one end of the limiting plate 302d is provided as an inclined surface. After the swing lever 302a is moved, in order to prevent the closing plate 301b from being closed by the rotating force of the first torsion spring 301c, the swing lever 302a will extrude the limiting plate 302d to open it, and then the swing lever 302a will enter the limiting slot. At this time, the limiting plate 302d will return to its original position to limit the swing lever 302a, thereby limiting the swing lever 302a. The positioning frame 302e is fixed on one side of the collection frame 301a, and the limiting plate 302d can be supported by the positioning frame 302e to prevent the limiting plate 302d from deviating.

[0053] Specifically, the positioning frame 302e is fixed on one side of the second torsion spring 302f, and the second torsion spring 302f is fixed on one side of the limiting plate 302d.

[0054] When it is necessary to release the limiting of the swing lever 302a, the limiting plate 302d is moved, and at this time the limiting plate 302d is separated from the swing lever 302a, so that the limiting of the swing lever 302a can be released. When the limiting plate 302d is moved, a torsional force can be applied to the second torsion spring 302f. When the limiting plate 302d is released, the second torsion spring 302f can drive the limiting plate 302d to return to its original position by the rotating force.

[0055] Specifically, the main assembly 100 is arranged on the support frame 202c and includes a discharge port 101 and an extruder body 102. The discharge port 101 is fixed on one side of the support frame 202c, and the extruder body 102 is fixed on one end of the discharge port 101.

[0056] The discharge port 101 is the final extrusion site of the plastic melt. After a series of processes such as heating, plasticizing and conveying of the plastic raw material by the extruder body 102, the plastic melt is extruded from the discharge port 101 under the pushing of the screw. The extruder body 102 is responsible for conveying the plastic particles entering from the hopper along the screw groove, and gradually compressing and heating the raw material during the conveying process.

[0057] In use, when the outer circle of the discharge port 101 needs to be scraped, the swing lever 302a is moved, which can drive the connecting frame 302c to move, and the connecting frame 302c can drive the pulley 302b to slide in the sliding groove when moving, which can support the swing lever 302a at this time to prevent the swing lever 302a from deviating when moving, and the swing lever 302a can drive the closing plate 301b to move to open it, and the first torsional spring 301c can be twisted when the closing plate 301b is opened. In order to prevent the closing plate 301b from being closed by the reverse rotation of the first torsional spring 301c, the swing lever 302a will extrude the limiting plate 302d to open it, and the limiting plate 302d can exert a torsional force on the second torsional spring 302f when moving, and then the swing lever 302a will enter the limiting groove, and at this time the limiting plate 302d will return to the original position by the reverse rotation of the second torsional spring 302f to limit the swing lever 302a, so that the closing plate 301b can be opened to form an inclined surface.

[0058] Then the handle 202a is moved, which can drive the driving rod 201d to flip, and the driving rod 201d can drive the moving frame 201c to move, and the moving frame 201c can drive the moving rod 201b to move, and the moving rod 201b can drive the scraper 201a to move on one side of the supporting frame 202c, and the scraper 201a can drive the sliding block 202d to move when moving, and the supporting strip 202e can be extruded by the sliding block 202d when moving, and the spring 202f can be extruded by the supporting strip 202e when moving, and at this time the scraper 201a can move on one side of the supporting frame 202c, so that the residual plastic melt on the outer circle of the discharge port 101 can be scraped, and when the supporting strip 202e moves to drive the scraper 201a to scrape the plastic melt, the handle 202a is released, and the supporting strip 202e can return to the original position by the rebounding force of the spring 202f, and then the limiting of the swing lever 302a is released, and at this time the closing plate 301b can be closed by the reverse rotation of the first torsional spring 301c.
