Description

Technical Field

[0001] The present application relates to the field of tool connection mechanisms, and particularly to a tool connection mechanism for an underwater pelletizer. Background Art

[0002] An underwater pelletizer is a device that cuts molten materials into granular form during the processing of materials such as plastics and rubbers. Its working principle mainly involves cutting underwater, using the cooling effect of water to reduce the temperature of the molten material, thereby preventing the material from sticking or deforming due to high temperature during the cutting process.

[0003] Most of the existing tools of underwater pelletizers are connected and fixed by bolts. However, due to the bolt connection method, it is easy to cause the connection between the tool and the die seat to be insufficiently tight, thereby affecting the sealing performance between the tool and the die seat. Summary of the Utility Model

[0004] In order to improve the sealing performance between the tool and the die seat, the present application provides a tool connection mechanism for an underwater pelletizer.

[0005] A tool connection mechanism for an underwater pelletizer provided by the present application adopts the following technical solutions:

[0006] A tool connection mechanism for an underwater pelletizer includes a tool mounting seat and a die seat. A first connection seat is provided on the tool mounting seat, and a second connection seat is provided on the die seat. An installation groove is formed on the second connection seat, and the first connection seat can be inserted into the installation groove. A second limiting block is provided on the side wall of the installation groove, and a first limiting block is installed on the first connection seat corresponding to the second limiting block, and the first limiting block can be in mutual contact with the second limiting block.

[0007] By adopting the above technical solutions, the first connection seat is installed on the tool mounting seat, the second connection seat is installed on the die seat. The first connection seat is provided with a first limiting block, the second connection seat is provided with an installation groove, and a second limiting block is installed on the circumferential part of the inner side wall of the installation groove. The first limiting block is inserted into the installation groove, and then the tool mounting seat is rotated, and the first limiting block is in mutual contact with the second limiting block, thereby tightly connecting the tool mounting seat and the die seat, and thus improving the sealing performance between the tool mounting seat and the die seat.

[0008] In a specific feasible embodiment, a plurality of the second limiting blocks are provided, and the plurality of second limiting blocks are installed on the circumferential part of the side wall of the installation groove, and the number of the first limiting blocks is set corresponding to the number of the second limiting blocks.

[0009] By adopting the above technical solution, a plurality of first limiting blocks are provided, and a plurality of second limiting blocks are correspondingly provided for the first limiting blocks. Thus, the tool mounting seat and the mold seat are connected by the mutual abutment of the plurality of first limiting blocks and the second limiting blocks, further improving the tightness of the connection between the tool mounting seat and the mold seat.

[0010] In a specific feasible implementation, the wall thickness of the inner side of the second limiting block facing the mounting groove is set to increase from small to large along the rotation direction of the tool mounting seat.

[0011] By adopting the above technical solution, the wall thickness of the second limiting block facing the mounting groove is set to increase from small to large along the rotation direction of the tool mounting seat. Thus, when the tool mounting seat is installed and screwed in, the tightness of the abutment between the first limiting block and the second limiting block is further ensured.

[0012] In a specific feasible implementation, four first limiting blocks and four second limiting blocks are provided. The four second limiting blocks are evenly and symmetrically arranged on the circumferential part of the side wall of the tool connecting seat, and the four first limiting blocks are correspondingly arranged for the second limiting blocks.

[0013] By adopting the above technical solution, four first limiting blocks and four second limiting blocks are provided. The four first limiting blocks are evenly and symmetrically installed on the circumferential part of the tool connecting seat, so as to ensure that the tool mounting seat is evenly stressed when it is screwed tightly on the mold seat, avoiding the problem of uneven stress and insufficient tightness of the connection at some parts.

[0014] In a specific feasible implementation, a clamping block is provided on the first limiting block, and a limiting groove is correspondingly opened on the mold seat for the clamping block.

[0015] By adopting the above technical solution, a clamping block is provided on the first limiting block, and a limiting groove is correspondingly opened on the mold seat for the clamping block. The clamping block can abut tightly against the side wall of the clamping block, thus preventing the tool mounting seat from rotating too much and causing damage to the first limiting block and the second limiting block.

[0016] In a specific feasible implementation, the clamping block is set as an inclined block, and the thickness of the clamping block is set to increase from small to large along the rotation direction of the tool mounting seat.

[0017] By adopting the above technical solution, the clamping block is set as an inclined block, and the thickness of the clamping block is set to increase from small to large along the rotation direction of the tool mounting seat. As the tool mounting seat is screwed in, it is prevented that the clamping block abuts and jams with the tool mounting seat, affecting the installation of the tool mounting seat.

[0018] In a specific feasible implementation, the first limiting block is set as an arc-shaped block, and the shape of the second limiting block corresponds to that of the first limiting block.

[0019] By adopting the above technical solution, the first limiting block is set as an arc-shaped block corresponding to the size of the tool mounting seat, and the shape of the second limiting block corresponds to that of the first limiting block, thereby reducing the occupied space of the first limiting block and the second limiting block.

[0020] In a specific feasible embodiment, a ring groove is formed on the second connecting seat, and a sealing ring is installed in the ring groove.

[0021] By adopting the above technical solution, a ring groove is formed on the second connecting seat, the sealing ring is installed in the ring groove, the tool mounting seat abuts against the sealing ring, the sealing ring deforms, and the connection tightness between the tool mounting seat and the mold seat is ensured.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The first connecting seat is installed on the tool mounting seat, the second connecting seat is installed on the mold seat, the first connecting seat is provided with a first limiting block, the second connecting seat is provided with a mounting groove, and a second limiting block is installed on the circumferential part of the inner side wall of the mounting groove. The first limiting block is inserted into the mounting groove, and then the tool mounting seat is rotated, and the first limiting block and the second limiting block are in mutual contact, thereby tightly connecting the tool mounting seat and the mold seat, and improving the sealing performance between the tool mounting seat and the mold seat;

[0024] 2. The wall thickness of the second limiting block on the side facing the mounting groove is set from small to large along the rotation direction of the tool mounting seat, so as to further ensure the tightness of the contact between the first limiting block and the second limiting block when the tool mounting seat is installed and screwed in;

[0025] 3. A ring groove is formed on the second connecting seat, the sealing ring is installed in the ring groove, the tool mounting seat abuts against the sealing ring, the sealing ring deforms, and the connection tightness between the tool mounting seat and the mold seat is ensured.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] In this specification, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

[0031] The embodiment of the present application discloses a tool connection mechanism for an underwater pelletizer.

[0032] like Figure 1 As shown, the underwater pelletizer tool connection mechanism includes a tool mounting seat 1 and a mold seat 2. The tool mounting seat 1 is provided with an active connection mechanism, and the mold seat 2 is provided with an auxiliary connection mechanism. The tool mounting seat 1 is driven to rotate by a pneumatic drive device, and the tool mounting seat 1 cooperates with the auxiliary connection mechanism through the active connection mechanism, thereby being connected to the mold seat 2.

[0033] like Figure 2 As shown, the active connection mechanism includes a first connecting seat 3 and a first limit block 4. The first connecting seat 3 is installed on the tool mounting seat 1. The first connecting seat 3 can be set as a circular seat. Four first limit blocks 4 are provided. The four first limit blocks 4 are symmetrically and evenly installed on the circumferential part of the first connecting seat 3. The first limit block 4 is preferably set as an arc block corresponding to the shape of the first limit seat.

[0034] The auxiliary connecting mechanism includes a second connecting seat 5 and a second limit block 6. The second connecting seat 5 is installed on the mold seat 2. The second connecting seat 5 can be set as a circular seat. Four second limit blocks 6 are provided. A mounting groove 51 is opened on the second connecting seat 5. The four second limit blocks 6 are arranged on the circumferential part of the inner wall of the mounting groove 51 corresponding to the position where the first limit block 4 is installed on the first mounting seat. The shape of the second limit block 6 is set corresponding to the first limit block 4. The surface of the second limit block 6 facing away from the mounting groove 51 is on the same horizontal plane as the end face of the first connecting seat 3 on the side where the mounting groove 51 is opened. The surface of the second limit block 6 facing the mounting groove 51 is set as an arcuate surface, and the thickness of this side of the second limit block 6 is set from small to large along the rotation direction of the tool mounting seat 1.

[0035] The first connecting seat 3 is installed on the tool mounting seat 1, and the second connecting seat 5 is installed on the mold seat 2. The first connecting seat 3 is provided with a first limit block 4, and the second connecting seat 5 is provided with a mounting groove 51. The second limit block 6 is installed on the circumferential part of the inner wall of the mounting groove 51. The first limit block 4 is inserted into the mounting groove 51, and then the tool mounting seat 1 is rotated. The first limit block 4 and the second limit block 6 abut against each other, and because the wall thickness of the second limit block 6 on the side facing the mounting groove 51 is set from small to large as the tool mounting seat 1 rotates, when the tool mounting seat 1 is installed and screwed in, the tightness of the first limit block 4 and the second limit block 6 is further guaranteed.

[0036] A clamping block 41 is installed on the surface of the first limit block 4 on the side facing away from the tool mounting seat 1. The clamping block 41 is preferably set as an inclined block. The thickness of the clamping block 41 is set from small to large along the rotation direction of the tool mounting seat 1. A limiting groove 52 is provided on the side wall of the mounting groove 51 provided on the second connecting seat 5 corresponding to the clamping block 41, and the limiting groove 52 is provided with an arc groove.

[0037] A clamping block 41 is arranged on the first limit block 4, and a clamping groove is opened on the mold base 2 corresponding to the clamping block 41. The clamping block 41 can be pressed against the side wall of the clamping block 41, so as to prevent the tool mounting seat 1 from rotating too much and causing damage to the first limit block 4 and the second limit block 6. At the same time, the clamping block 41 is arranged as an inclined block, and the thickness of the clamping block 41 is arranged from small to large along the rotation direction of the tool mounting seat 1. As the tool mounting seat 1 is screwed in, the clamping block 41 is prevented from being stuck with the tool mounting seat 1.

[0038] An annular groove 53 is provided on the side wall of the mounting groove 51 on the second connecting seat 5, and a sealing ring 7 is provided in the annular groove 53. The sealing ring 7 is made of a material with waterproof and sealing properties such as rubber or silicone. As the tool mounting seat 1 rotates and with the cooperation of the first limit block 4 and the second limit block 6, the distance between the tool mounting seat 1 and the mold seat 2 gradually decreases, the tool mounting seat 1 squeezes the sealing ring 7, the sealing ring 7 is deformed, and the gap between the tool mounting seat 1 and the mold seat 2 is sealed, thereby improving the sealing of the two.

[0039] The implementation principle of a tool connection mechanism of an underwater pelletizer in an embodiment of the present application is as follows: The first connecting seat 3 is installed on the tool mounting seat 1, the second connecting seat 5 is installed on the die seat 2, a first limiting block 4 is provided on the first connecting seat 3, an installation groove 51 is formed on the second connecting seat 5, and a second limiting block 6 is installed on the circumferential part of the inner side wall of the installation groove 51. The first limiting block 4 is inserted into the installation groove 51, and then the tool mounting seat 1 is rotated. The first limiting block 4 and the second limiting block 6 are in mutual contact. Since the wall thickness of the second limiting block 6 on the side facing the installation groove 51 is set to increase from small to large in the rotation direction of the tool mounting seat 1, when the tool mounting seat 1 is installed and screwed in, the tightness of the contact between the first limiting block 4 and the second limiting block 6 is further ensured. The clamping block 41 is in tight contact with the side wall of the clamping block 41, thereby preventing the tool mounting seat 1 from rotating too much, causing damage to the first limiting block 4 and the second limiting block 6, and preventing the clamping block 41 from being stuck in contact with the tool mounting seat 1. With the rotation of the tool mounting seat 1 and under the cooperation of the first limiting block 4 and the second limiting block 6, the distance between the tool mounting seat 1 and the die seat 2 gradually decreases. The tool mounting seat 1 presses the sealing ring 7, and the sealing ring 7 deforms to seal the gap between the tool mounting seat 1 and the die seat 2, thereby improving the sealing performance between the two.

[0040] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
