Description

Technical Field

[0001] This utility model relates to the field of polymer material processing technology, and in particular to a multifunctional adjustable two-stage extrusion unit. Background Technology

[0002] A two-stage extruder is a polymer material processing equipment consisting of two extrusion units. It first pre-processes the polymer raw material, then performs further processing, and finally extrudes it through a die to produce polymer products of various shapes. Adjustable two-stage extruders are adjustable, allowing the screw speed to be adjusted as needed. This changes the material's conveying speed, plasticization, and mixing degree within each stage of the extruder. The heating temperature of each stage can be flexibly adjusted to adapt to the processing characteristics of different polymer materials. A die is installed at one end of the extruder. The extruder conveys the processed polymer material to the die, where it is extruded according to the pre-designed specifications, ultimately producing various polymer material products that meet the corresponding requirements. When product specifications change, a new die is needed to ensure accurate product dimensions. During die switching, the current die is usually removed from the extruder outlet before a new die is installed. This process is quite cumbersome and time-consuming, impacting production efficiency to some extent. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides a multi-functional adjustable two-stage extruder unit. The multi-functional adjustable two-stage extruder unit includes a main component 100 and a discharge component 200. The two work together to set multiple molds on one side of the extruder discharge port. When mold switching is required, a wheel switching method is used, which can conveniently and quickly change the molds, simplify the operation, and reduce the complexity and workload of manual labor.

[0032] The main component 100 includes a two-stage extruder 101, with a discharge port 102 fixed at one end of the two-stage extruder 101 and a base 103 fixed at the bottom of the two-stage extruder 101.

[0033] The two-stage extruder 101 is used to heat, plasticize, and mix materials such as polymers in multiple stages to bring them to a state suitable for extrusion molding. The discharge port 102 provides an output channel for the material after it has been processed by the two-stage extruder 101, so that the material can flow to the subsequent mold for shaping. The base 103 mainly plays the role of stabilizing and supporting the two-stage extruder 101 to ensure that the two-stage extruder 101 remains stable during operation and can carry out processing work normally.

[0034] The discharge assembly 200 is disposed on the discharge port 102 and includes a discharge component 201. The discharge component 201 includes a first clamping ring 201a. A second clamping ring 201b is hinged to the top of the first clamping ring 201a. A limit strip 201c is fixed to one side of the second clamping ring 201b. A limit block 201d is provided on one side of the limit strip 201c. A moving strip 201e is fixed to one side of the limit block 201d. The moving strip 201e is inserted into one side of the first clamping ring 201a. The moving strip 201e and the first clamping ring 201a are movably connected. A switching rod 201f is fixed to one side of the first clamping ring 201a.

[0035] The discharge components 201 are in three sets, all located on one side of the discharge port 102. By placing the mold on the first clamping ring 201a and then moving the second clamping ring 201b, a limiting groove corresponding to the limiting block 201d is formed on one side of the limiting strip 201c. The limiting block 201d is set as an inclined surface. When the second clamping ring 201b moves to fix the mold, it will cause the limiting strip 201c to move on the side of the limiting block 201d. At this time, the limiting block 201d will not limit the limiting strip 201c. After the mold is fixed, the limiting block 201d can limit the limiting strip 201c. c provides unidirectional limiting to prevent the second clamping ring 201b from moving on its own and causing the clamping of the mold to loosen. When the mold needs to be removed, the limiting block 201d is moved to separate from the limiting strip 201c. A torsion spring is fixed on one side of the second clamping ring 201b, and one end of the torsion spring is fixed to the inner wall of the first clamping ring 201a. When the first clamping ring 201a is moved to engage with the second clamping ring 201b, the torsion spring can apply a torsional force. When the separation of the limiting strip 201c is released, the force of the torsion spring rotation can drive the first clamping ring 201a back to its original position and separate from the mold, thus removing the mold.

[0036] Three different molds can be clamped by three sets of first clamping rings 201a and second clamping rings 201b. When it is necessary to switch molds, the first clamping ring 201a can be moved by the movement of the switching rod 201f. The mold can be quickly switched by moving the first clamping ring 201a. A sealing ring is fixed on one side of the first clamping ring 201a and the second clamping ring 201b, and a sealing ring is fixed on the side of the discharge port 102. When the first clamping ring 201a and the second clamping ring 201b are moved to the side of the discharge port 102, the two sealing rings will squeeze each other to prevent leakage during discharge.

[0037] First, place the mold to be used on the first clamping ring 201a on one side of the discharge port 102. Then, move the second clamping ring 201b to close it with the first clamping ring 201a to fix the mold. When the second clamping ring 201b is moved, the limiting strip 201c on one side will move on the limiting block 201d. Since the limiting block 201d is an inclined surface, it will not be limited at this time. After the mold is fixed, the limiting block 201d forms a one-way limit on the limiting strip 201c to prevent the second clamping ring 201b from moving on its own and causing the mold clamping to loosen. Following the above steps, use three sets of discharge parts 201 to clamp three different molds on one side of the discharge port 102 respectively, and then move the first clamping ring 201a and the second clamping ring 201b to close it with the first clamping ring 201a to fix the mold. When the clamping rings 201b move to the side of the discharge port 102, they press against the sealing ring fixed on the side of the discharge port 102 to prevent leakage during discharge. To switch molds, move the corresponding switching rod 201f. The switching rod 201f drives the first clamping ring 201a to move, and the first clamping ring 201a drives the corresponding mold to move, thereby achieving rapid mold switching. When the mold needs to be removed, first move the limiting block 201d to separate it from the limiting strip 201c. Since the torsion spring fixed on the side of the second clamping ring 201b was previously twisted and stored, after the limiting strip 201c is released, the force of the torsion spring will drive the first clamping ring 201a back to its original position and separate it from the mold, so that the mold can be removed.

[0038] Example 2

[0039] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the discharge assembly 200 also includes a switching component 202, which includes a switching disk 202a. The switching disk 202a is fixed to one end of the switching rod 201f. A fixed block 202b is provided on one side of the switching disk 202a. A first spring 202c is fixed on one side of the fixed block 202b. A positioning sleeve 202d is sleeved on the outside of the first spring 202c.

[0041] A fixed-point groove corresponding to the fixed-point block 202b is provided on one side of the switching disk 202a. When the switching disk 202a is rotated, the switching rod 201f can be moved, thereby enabling rapid switching of the mold. When the mold is switched to the discharge port 102 side, in order to prevent the switching disk 202a from rotating on its own, the fixed-point groove and the fixed-point block 202b can be engaged to limit the switching disk 202a, preventing the mold from shifting due to the switching disk 202a rotating on its own.

[0042] When it is necessary to release the limit on the switching disk 202a, the fixed block 202b is squeezed. At this time, the fixed block 202b can apply a squeezing force to the first spring 202c. After the limit is released, the switching disk 202a is rotated. There are three fixed slots on the switching disk 202a. When the next fixed slot moves to the side of the fixed block 202b, the rebound force of the first spring 202c drives the fixed block 202b to return to its original position and re-engage with the fixed slot, thus limiting the switching disk 202a. At this time, the mold is just aligned with the discharge port 102. The positioning sleeve 202d is sleeved on the outside of the fixed block 202b. The positioning sleeve 202d and the fixed block 202b are movably connected. The positioning sleeve 202d can support the fixed block 202b and prevent the fixed block 202b from shifting.

[0043] Specifically, a drive column 202e is inserted into one side of the switching disk 202a, and a positioning plate 202f is provided at one end of the drive column 202e. The positioning plate 202f and the drive column 202e are rotatably connected by a rotating shaft.

[0044] When the switching disk 202a rotates, it can drive the drive column 202e to rotate. The rotation of the drive column 202e can support the switching disk 202a and prevent the switching disk 202a from shifting. The positioning plate 202f is fixed to one side of the positioning sleeve 202d and is fixed to the top of the two-stage extruder 101. The positioning plate 202f can support the drive column 202e.

[0045] Specifically, the discharge assembly 200 also includes a limiting component 203, which includes a limiting ring 203a, and the limiting ring 203a is fixed to the inner wall of the positioning plate 202f.

[0046] There are two limiting rings 203a, both fixed to the inner wall of the positioning plate 202f. Each limiting ring 203a has a one-way groove corresponding to the inclined block 203b. The one-way grooves on both limiting rings 203a are opposite in direction, allowing for one-way limiting of the inclined block 203b. When the inclined block 203b rotates within the limiting rings 203a, it can only rotate in one direction, thus allowing the first clamping ring 201a to rotate in one direction. When it is necessary to rotate the first clamping ring 201a in the other direction... By moving the inclined block 203b to engage with another limiting ring 203a and separating it from the first limiting ring 203a, the inclined block 203b can rotate in another direction. This allows for unidirectional limiting of the inclined block 203b in another direction. Each rotation mode can be switched to rotate the first clamping ring 201a in one direction, ensuring that the direction is clear, stable and controllable during mold switching. This avoids positioning inaccuracies that may be caused by random bidirectional rotation, thus enabling more precise and efficient mold switching.

[0047] Specifically, a ramp block 203b is provided on one side of the limiting ring 203a, a movable column 203c is fixed at the bottom of the ramp block 203b, and a second spring 203d is fixed at the bottom of the movable column 203c.

[0048] When the inclined block 203b rotates within the limiting ring 203a, the one-way groove within the inclined block 203b can compress the inclined block 203b, causing it to move. The movement of the inclined block 203b can drive the movable column 203c to move. At this time, the movable column 203c can apply a compressive force to the second spring 203d. When the inclined block 203b rotates to the point where it separates from the one-way groove and engages with the next one-way groove, the rebound force of the second spring 203d can drive the inclined block 203b back to its original position and engage with the one-way groove. By repeating this process, the inclined block 203b and the one-way groove can remain engaged. At this time, the one-way groove can be used to limit the inclined block 203b in one direction, preventing the inclined block 203b from reversing.

[0049] Specifically, a connecting rod 203e is sleeved on the outside of the movable column 203c. The connecting rod 203e is sleeved on the outside of the movable column 203c, and the connecting rod 203e and the movable column 203c are movably connected.

[0050] The connecting rod 203e is inserted into one side of the positioning plate 202f. The connecting rod 203e and the positioning plate 202f are rotatably connected via a rotating shaft. The connecting rod 203e is also inserted into one side of the drive column 202e. The connecting rod 203e and the drive column 202e are movably connected. When the connecting rod 203e is rotated, it can drive the drive column 202e to rotate. At this time, the rotation of the drive column 202e can drive the switching disk 202a to rotate, thereby allowing the mold to be switched. When the connecting rod 203e rotates, it can drive the inclined block 203b to rotate within the limiting ring 203a. By limiting the inclined block 203b through the limiting ring 203a, the connecting rod 203e can be limited, thereby limiting the drive column 202e, and thus limiting the rotation direction of the mold.

[0051] Specifically, a slider 203f is sleeved on the outside of the connecting rod 203e, and a groove X corresponding to the slider 203f is opened in the drive column 202e. The slider 203f and the groove X are slidably connected.

[0052] When the connecting rod 203e moves, it can drive the slider 203f to slide in the groove X, thereby supporting the connecting rod 203e and preventing it from shifting. When the connecting rod 203e rotates, it can drive the slider 203f to press against the groove X, thereby causing the drive column 202e to rotate. The rotation of the drive column 202e can then drive the switching disk 202a to rotate.

[0053] First, place the mold on the first clamping ring 201a on one side of the discharge port 102. The first clamping ring 201a and the second clamping ring 201b work together to clamp and fix the mold, ensuring that the molds at the three sets of discharge parts 201 are all installed and that the sealing rings of each component are pressed against each other to prevent leakage. Then, hold the connecting rod 203e and rotate it. The rotation of the connecting rod 203e drives the drive column 202e to rotate, which in turn drives the switching disk 202a to rotate. When the switching disk 202a rotates, it drives the switching rod 201f to move, thereby realizing the mold switching operation. During this process, when the connecting rod 203e rotates, it drives the inclined block 203b to rotate within the limiting ring 203a. The limiting ring 203a limits the inclined block 203b in one direction, thereby limiting the rotation direction of the connecting rod 203e, the drive column 202e and the switching disk 202a, ensuring that the mold switching direction is clear, stable and controllable.Simultaneously, when the connecting rod 203e moves, it drives the slider 203f to slide within the groove X in the drive column 202e, providing support for the connecting rod 203e and preventing it from shifting. When rotating, the slider 203f presses against the groove X, causing the drive column 202e to rotate. After the mold is switched to a suitable position on the discharge port 102 side, to prevent the switching disc 202a from rotating on its own, the fixed-point groove on the switching disc 202a engages with the fixed-point block 202b to limit the switching disc 202a. At this time, the positioning sleeve 202d acts as a support for the fixed-point block 202b. The mold provides support and prevents it from shifting. If the mold needs to be switched again, the fixed point block 202b is pressed, which in turn presses the first spring 202c, releasing the engagement limit between the fixed point block 202b and the fixed point groove. Then, the switching disk 202a is rotated again to switch the mold. When the next fixed point groove moves to the side of the fixed point block 202b, the first spring 202c rebounds, causing the fixed point block 202b to return to its original position and re-engage with the fixed point groove, thus limiting the switching disk 202a. At this time, the mold is aligned with the discharge port 102 again. When it is necessary to switch the mold again... When one clamping ring 201a rotates in another direction, the inclined block 203b moves to engage with another limiting ring 203a, separating it from the currently limiting ring 203a. This allows the inclined block 203b to rotate in the other direction, achieving unidirectional rotation of the first clamping ring 201a in another direction, meeting different mold switching requirements. During the rotation of the inclined block 203b within the limiting ring 203a, the unidirectional groove compresses the inclined block 203b, causing it to move. The inclined block 203b then drives the movable column 203c to move. The movable column 203c compresses the second spring 203d. When the inclined block 203b rotates to separate from the one-way groove and engage with the next one-way groove, the second spring 203d rebounds, causing the inclined block 203b to return to its original position and engage with the one-way groove, maintaining the engaged state to achieve one-way limiting and prevent the inclined block 203b from reversing. Following the mold removal method in the previous embodiment, the limiting block 201d is moved to separate from the limiting strip 201c. With the help of the force of the torsion spring rotation, the first clamping ring 201a returns to its original position and separates from the mold, thereby removing the mold.

[0054] Example 3

[0055] Reference Figures 1 to 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0056] Specifically, a pressure plate 203g is sleeved on the outside of the connecting rod 203e, and a third spring 203h is fixed on one side of the pressure plate 203g. The third spring 203h is fixed to the inner wall of the drive column 202e.

[0057] When it is necessary to engage the inclined block 203b with another limiting ring 203a to change the rotation direction, the connecting rod 203e is pulled. The movement of the connecting rod 203e will move the inclined block 203b into the other limiting ring 203a. The movement of the connecting rod 203e will also move the pressure plate 203g. The movement of the pressure plate 203g will apply a squeezing force to the third spring 203h. When it is necessary to return the inclined block 203b to its original position and engage with the initial limiting ring 203a, the connecting rod 203e is released. The rebound force of the third spring 203h will then move the inclined block 203b back to its original position and engage with the initial limiting ring 203a, thus changing the initial rotation direction.

[0058] Specifically, the discharge assembly 200 also includes a toggle member 204, which includes a connecting plate 204a. The connecting plate 204a is sleeved on the outside of the moving strip 201e. A fourth spring 204b is fixed on one side of the connecting plate 204a, and one end of the fourth spring 204b is fixed to the inner wall of the first clamping ring 201a.

[0059] When it is necessary to move the moving bar 201e to release the limit bar 201c, the moving bar 201e can move the connecting plate 204a. At this time, the movement of the connecting plate 204a can apply a squeezing force to the fourth spring 204b. The movement of the moving bar 201e can then separate the limit block 201d and the limit bar 201c. Then, the force of the torsion spring rotation can drive the second clamping ring 201b to return to its original position and release the clamping of the mold, thus allowing it to be removed. After removal, the moving bar 201e is released, and the force of the fourth spring 204b rebound can cause the limit block 201d and the limit bar 201c to re-engage for the next use.

[0060] Specifically, a lever 204c is hinged to one end of the moving bar 201e, and one end of the lever 204c is hinged to one side of the first clamping ring 201a. A lever block 204d is fixed to one end of the lever 204c.

[0061] Moving the lever 204d can move the lever 204c, which in turn moves the moving bar 201e, thereby releasing the limit on the second clamping ring 201b.

[0062] In use, first place the molds to be used sequentially on the first clamping rings 201a corresponding to the three sets of discharge parts 201 on one side of the discharge port 102. For each mold, move the second clamping ring 201b to close with the first clamping ring 201a. During the movement, the limiting strip 201c on one side of the second clamping ring 201b will move and fix the mold on the side of the limiting block 201d. After the mold is fixed, the limiting block 201d forms a one-way limit on the limiting strip 201c to prevent the second clamping ring 201b from moving on its own. This causes the mold clamping to loosen. When moving the first clamping ring 201a and the second clamping ring 201b to the side of the discharge port 102, ensure that they are pressed against the sealing ring fixed on the side of the discharge port 102 to prevent leakage. Then, hold the connecting rod 203e and rotate it. The rotation of the connecting rod 203e drives the drive column 202e to rotate. The rotation of the drive column 202e drives the switching disk 202a to rotate. The rotation of the switching disk 202a drives the switching rod 201f to move, thereby realizing the mold switching operation.

[0063] When the connecting rod 203e is rotated, it drives the inclined block 203b to rotate within the limiting ring 203a. The limiting ring 203a provides unidirectional limitation for the inclined block 203b, thereby limiting the rotation direction of the connecting rod 203e, the drive column 202e, and the switching disk 202a, ensuring that the mold switching direction is clear, stable, and controllable. At the same time, when the connecting rod 203e moves, it drives the slider 203f to slide within the groove X in the drive column 202e, which supports the connecting rod 203e and prevents it from deviating. When rotating, the slider 203f presses against the groove X, causing the drive column 202e to rotate.

[0064] After the mold is switched to a suitable position on the side of the discharge port 102, the fixed slot on the switching disk 202a engages with the fixed block 202b to limit the switching disk 202a and prevent it from rotating on its own and causing the mold to shift. At this time, the positioning sleeve 202d supports the fixed block 202b to prevent it from shifting. If the mold needs to be switched again, the fixed block 202b is squeezed to squeeze the first spring 202c, releasing the engagement and limiting of the fixed block 202b with the fixed slot. Then the switching disk 202a is rotated again to switch the mold. When the next fixed slot moves to the side of the fixed block 202b, the first spring 202c rebounds and drives the fixed block 202b back to its original position and engages with the fixed slot again, thus limiting the switching disk 202a. At this time, the mold is aligned with the discharge port 102 again.

[0065] When the first clamping ring 201a needs to rotate in another direction, the connecting rod 203e is pulled, causing the inclined block 203b to move into another limiting ring 203a. During this process, the connecting rod 203e moves, causing the pressure plate 203g to move. The pressure plate 203g applies a squeezing force to the third spring 203h, allowing the inclined block 203b to rotate in another direction, thus achieving unidirectional rotation of the first clamping ring 201a in another direction and meeting different mold switching requirements. When it is necessary to return the inclined block 203b to its original position and engage with the initial limiting ring 203a to return to the initial rotation direction, the connecting rod 203e is released, and the rebound force of the third spring 203h causes the inclined block 203b to return to its original position and engage with the initial limiting ring 203a.

[0066] To remove the mold, the lever 204d can be moved, which in turn moves the lever 204c, which in turn moves the moving bar 201e, which in turn moves the connecting plate 204a. The connecting plate 204a applies a compressive force to the fourth spring 204b. Simultaneously, the movement of the moving bar 201e causes the limiting block 201d and the limiting bar 201c to separate. Since the torsion spring fixed on one side of the second clamping ring 201b was previously twisted and stored, after the limiting bar 201c is released, the force of the torsion spring's rotation causes the second clamping ring 201b to return to its original position and release the clamp on the mold, allowing the mold to be removed. After removing the mold, the moving bar 201e is released, and the force of the fourth spring 204b's rebound causes the limiting block 201d and the limiting bar 201c to re-engage for the next use.
