[0001] This utility model relates to the field of auxiliary equipment technology for extruders, specifically to a tooling for disassembling the blades of an extruder. Background Technology
[0002] The augers are one of the core components of an extruder, responsible for uniformly mixing the raw materials and propelling them into the heating and extrusion zone. The augers are generally detachably mounted on the extruder's shaft.
[0003] Currently, the main method for disassembling the extruder's blades is by using a hand-operated hoist and a hammer. The drawbacks of this method are that it is cumbersome and inconvenient to use, and the hand-operated hoist and hammer pose a significant safety hazard as they may injure the operator. Utility Model Content
[0004] In view of this, the present invention provides a tooling for disassembling the blades of an extruder, in order to solve the problems of cumbersome operation, inconvenience of use, and significant safety hazards in the existing disassembly of blades of an extruder.
[0005] This utility model provides a tooling for disassembling the blades of an extruder, including:
[0006] The tooling body has an upward-facing receiving groove along its length. One side of the tooling body along its length has an opening communicating with the receiving groove, and the opposite side has an abutment part. Multiple pairs of mounting holes are spaced apart along the length on opposite sides of the tooling body along its width, with the pairs of mounting holes facing each other.
[0007] A fastener, inserted into one of the pair of mounting holes, is adapted to abut against the blades of the extruder;
[0008] The jack has one end abutting with the abutting part, and the other end is adapted to abut the end of the extruder's shaft. The fixing member and the abutting part together clamp the jack and the extruder's blades.
[0009] Beneficial Effects: The extruder blade disassembly fixture provided by this utility model allows for the following steps: First, the shaft containing the blades and a jack are placed in the receiving groove of the fixture body. One end of the jack abuts against the abutment part of the fixture body, and the other end abuts against the shaft. A fixing member is inserted into a pair of mounting holes. The jack pushes the shaft outwards, causing the fixing member to abut against one section of the blade. The jack continues to push the shaft outwards, separating that section of blade from the shaft. This process is repeated to disassemble all blades. The shaft can then gradually detach from the receiving groove through the opening in the fixture body. Compared to traditional disassembly methods using a hand chain hoist and hammer, this utility model offers a convenient and quick blade disassembly process while ensuring operator safety.
[0010] In one optional embodiment, the paired mounting holes include a first sub-mounting hole and a second sub-mounting hole, which are respectively located on opposite sides of the tooling body, and the size of the first sub-mounting hole is larger than the size of the second sub-mounting hole.
[0011] Beneficial effects: By setting first and second sub-mounting holes of different sizes, it is possible to prevent the fasteners from detaching from the mounting holes and improve the stability of hinge disassembly.
[0012] In one optional embodiment, the tooling body includes a first side plate and a second side plate disposed opposite to each other. The first side plate is provided with a plurality of first sub-mounting holes and a plurality of second sub-mounting holes located at the lower end of the plurality of first sub-mounting holes.

[0013] Beneficial effects: Each side of the tooling body is provided with a row of first sub-mounting holes and a row of second sub-mounting holes to facilitate the installation of fasteners. At the same time, it can also meet the disassembly requirements of blades of different sizes, thereby expanding the application range of the extruder blade disassembly tooling and facilitating its promotion.
[0014] In one alternative embodiment, the cross-sectional area of the fastener gradually decreases along its length, forming a large end and a small end. The large end passes through the first sub-mounting hole, and the small end passes through the second sub-mounting hole.
[0015] Beneficial effect: The size of the fastener is adapted to the size of the mounting hole, so as to ensure stable installation of the fastener.
[0016] In one alternative embodiment, a handle is also provided on the outer side of the large end.
[0017] Beneficial effect: By providing a handle on the outside of the large end, it is convenient for users to install and remove the fastener.
[0018] In one alternative embodiment, the handle extends along one side perpendicular to the length direction of the fastener, and when the fastener is inserted into the mounting hole, the inner side of the handle abuts against the outer side of the tooling body.
[0019] Beneficial effect: The handle also prevents the fastener from passing completely through the mounting hole, thus facilitating the installation of the fastener.
[0020] In one optional embodiment, the mounting hole is a regular hole, which includes square holes, round holes, and elliptical holes.
[0021] Beneficial effects: The mounting holes are regular holes, which makes it easier to open the holes and saves manufacturing costs. On the other hand, it makes it easier to insert fasteners and also avoids mutual wear between the fasteners and the hole walls.
[0022] In one alternative embodiment, the fixing member has an abutment surface on one side that is aligned with the spiral direction of the blade, and is adapted to abut against the blade through the abutment surface.
[0023] Beneficial effects: The fixing component has a contact surface that is aligned with the spiral direction of the blade, which facilitates the contact between the fixing component and the blade, ensuring that the blade is subjected to uniform force during disassembly and thus preventing damage to the blade.
[0024] In one optional embodiment, the mounting hole is a square hole, and the cross-section of the fastener is an isosceles trapezoid or a right trapezoid, with the inclined surface of the isosceles trapezoid or the right trapezoid serving as the abutment surface.
[0025] Beneficial effects: The cross-section of the fastener is an isosceles trapezoid or a right trapezoid, which facilitates the manufacturing of the fastener and further reduces manufacturing costs.
[0026] In one alternative embodiment, a pad is provided between the abutting part and the jack.
[0027] Beneficial effects: The pad is used to protect the contact part and the jack, preventing damage to the contact part and the jack, and helping to extend the service life of the extruder blade disassembly tool. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0033] The following is combined Figure 1 The following describes embodiments of the present invention.
[0034] According to the embodiment of the present utility model, Figure 1 As shown, a disassembly fixture for an extruder blade is provided, comprising: a fixture body 1, a fixing member 2, and a jack. The fixture body 1 has an upward-facing receiving groove 101 along its length. One side of the fixture body 1 along its length has an opening communicating with the receiving groove 101, and the opposite side has an abutment portion 102. Multiple pairs of mounting holes 103 are spaced apart along the length of opposite sides of the fixture body 1 in the width direction, with the pairs of mounting holes 103 facing each other. The fixing member 2 is inserted into one pair of mounting holes 103 and is adapted to abut against the extruder blade. One end of the jack abuts against the abutment portion 102, and the opposite end is adapted to abut against the end of the extruder shaft. The fixing member 2 and the abutment portion 102 together clamp the jack and the extruder blade.
[0035] The extruder blade disassembly fixture provided in this embodiment of the utility model involves first placing the auger shaft containing the blades and a jack into the receiving groove 101 of the fixture body 1. One end of the jack abuts against the abutment part 102 of the fixture body 1, and the other end abuts against the auger shaft. A fixing member 2 is inserted into a pair of mounting holes 103. The jack pushes the auger shaft outward, causing the fixing member 2 to abut against one section of the auger blade. The jack continues to push the auger shaft outward, separating that section of the auger blade from the auger shaft. This process is repeated to disassemble all the auger blades. The auger shaft can gradually detach from the receiving groove 101 from the opening of the fixture body 1. Compared to the traditional disassembly method using a hand-operated hoist and hammer, the blade disassembly process in this embodiment of the utility model is convenient and quick, and also ensures operator safety.
[0036] Specifically, the receiving groove 101 is used to hold the winch shaft equipped with the winch blade and the jack; therefore, the dimensions of the receiving groove 101 need to be adapted to fit the winch shaft and the jack. The opening of the fixture body 1 needs to allow the winch shaft to pass through. The length direction of the fixture body 1 is as follows: Figure 1 As shown by arrow A in the diagram.
[0037] It should be noted that this embodiment of the invention does not limit the materials of the tooling body 1 and the fastener 2; any existing material can be selected as needed. For example, the tooling body 1 and the fastener 2 can be made of metal, which has high structural strength.
[0038] Furthermore, this embodiment of the invention does not limit the structure of the jack, as long as the jack can push out the winch shaft. For example, the jack can be a mechanical jack, a hydraulic jack, etc.
[0039] In one embodiment, such as Figure 1 As shown, the paired mounting holes 103 include a first sub-mounting hole 1031 and a second sub-mounting hole 1032. The first sub-mounting hole 1031 and the second sub-mounting hole 1032 are respectively located on opposite sides of the tooling body 1, and the size of the first sub-mounting hole 1031 is larger than the size of the second sub-mounting hole 1032. For example, if the mounting hole 103 is a circular hole, then the diameter of the first sub-mounting hole 1031 is larger than the diameter of the second sub-mounting hole 1032. By setting the first sub-mounting hole 1031 and the second sub-mounting hole 1032 with different sizes, it is possible to prevent the fastener 2 from detaching from the mounting hole 103, thereby improving the stability of the hinge disassembly.
[0040] Furthermore, in one embodiment, such as Figure 1 As shown, the tooling body 1 includes a first side plate 104 and a second side plate 105 arranged opposite to each other. The first side plate 104 is provided with a plurality of first sub-mounting holes 1031 and a plurality of second sub-mounting holes 1032 located at the lower end of the plurality of first sub-mounting holes 1031. The second side plate 105 is provided with a plurality of second sub-mounting holes 1032 and a plurality of first sub-mounting holes 1031 located at the lower end of the plurality of second sub-mounting holes 1032.
[0041] Each side of the tooling body 1 is provided with a row of first sub-mounting holes 1031 and a row of second sub-mounting holes 1032 to facilitate the installation of the fastener 2, and can also meet the disassembly requirements of different sized blades, thereby expanding the application range of the extruder blade disassembly tooling and facilitating its promotion.
[0042] Furthermore, in one embodiment, such as Figure 1 As shown, the cross-sectional area of the fastener 2 gradually decreases along its length, forming a large end and a small end. Since the fastener 2 passes through a pair of mounting holes 103, the length direction of the fastener 2 is the width direction of the fixture body 1. The large end passes through the first sub-mounting hole 1031, and the small end passes through the second sub-mounting hole 1032. The size of the fastener 2 is adapted to the size of the mounting holes 103 to ensure stable installation of the fastener 2.
[0043] Furthermore, in one embodiment, such as Figure 1As shown, a handle 201 is also provided on the outer side of the large end. By providing a handle 201 on the outer side of the large end, it is convenient for users to install and remove the fastener 2.
[0044] In one embodiment, the handle 201 extends along one side perpendicular to the length direction of the fastener 2, and when the fastener 2 is inserted into the mounting hole 103, the inner side of the handle 201 abuts against the outer side of the tooling body 1. The handle 201 also prevents the fastener 2 from completely passing through the mounting hole 103, thus facilitating the installation of the fastener 2.
[0045] It should be noted that the shape of the mounting hole 103 is not limited in this embodiment of the utility model, and any existing shape can be selected as needed.
[0046] In one embodiment, the mounting hole 103 is a regular hole, including square holes, round holes, and elliptical holes. The regularity of the mounting hole 103 facilitates drilling and saves manufacturing costs, facilitates the insertion of the fastener 2, and also prevents mutual wear between the fastener 2 and the hole wall of the mounting hole 103.
[0047] Furthermore, this embodiment of the invention does not limit the number of mounting holes 103; two, three, or more pairs can be selected as needed.
[0048] In one embodiment, the fixing member 2 has an abutment surface on one side that is aligned with the spiral direction of the blade, and is adapted to abut against the blade through the abutment surface. The fixing member 2 is provided with an abutment surface aligned with the spiral direction of the blade, which facilitates the abutment between the fixing member 2 and the blade, and ensures that the blade is subjected to uniform force during disassembly, thereby avoiding damage to the blade.
[0049] Furthermore, in one embodiment, the mounting hole 103 is a square hole, and the cross-section of the fastener 2 is an isosceles trapezoid or a right trapezoid, with the inclined surface of the isosceles trapezoid or right trapezoid serving as the abutment surface. The isosceles trapezoid or right trapezoid cross-section of the fastener 2 facilitates its manufacture, thereby further reducing manufacturing costs.
[0050] In one embodiment, a pad is provided between the abutment part 102 and the jack. The pad is used to protect the abutment part 102 and the jack, prevent damage to the abutment part 102 and the jack, and help to extend the service life of the extruder blade disassembly tool.
[0051] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
