Detailed Embodiment

[0030] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

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

[0032] A frame for an underwater pelletizer includes a main frame 1 and a sub-frame 2. The main frame 1 and the sub-frame 2 are connected by a connecting plate, and a clamp 3 is installed on the sub-frame 2. A pelletizing device is slidably installed on the main frame 1, a cutting chamber is fixedly installed on the sub-frame 2, a conveying pipeline 5 is communicated with the cutting chamber, and the clamp 3 clamps the conveying pipeline 5.

[0033] The main frame 1 and the sub-frame 2 are connected by a connecting plate, which improves the overall stability of the main frame 1 and the sub-frame 2. The clamp 3 clamps the conveying pipeline 5, reducing the possibility of the conveying pipeline 5 shaking during operation.

[0034] A number of protective plates 4 are fixedly installed between the main frame 1 and the sub-frame 2. A storage space is formed among the main frame 1, the sub-frame 2 and the protective plates 4. Tools are placed inside the storage space to improve the utilization rate of the space and the convenience of maintenance.

[0035] The clamp 3 includes a mounting seat 31, a reference rod 32 and a clamping member 33.

[0036] The mounting seat 31 is fixedly installed on the side wall of the sub-frame 2.

[0037] The reference rod 32 is detachably and fixedly installed on the top of the mounting seat 31. The reference rod 32 includes a number of reference units 321 connected end to end. A guide groove 327 is vertically opened at the top of each reference unit 321, and a limit groove 328 is opened on the inner wall of the guide groove 327. A guide rod 322 and a limit block 323 are fixedly installed at the top of each reference unit 321. The guide rod 322 is coaxial with the reference unit 321, and the limit block 323 is fixedly installed at the bottom of the guide rod 322.

[0038] The guide rod 322 is inserted into the guide groove 327 in a plug-in fit, and the limit block 323 is slidably fitted with the limit groove 328. When splicing a number of reference units 321, the guide rod 322 is inserted into the adjacent guide groove 327 for preliminary positioning. Then, the two reference units 321 are rotated relative to each other so that the limit block 323 is located in the limit groove 328, and the limit block 323 is limited in the vertical direction by the inner wall of the limit groove 328.

[0039] To further improve the connection stability between two adjacent reference units 321, a first positioning hole 324 is vertically opened at the top of each reference unit 321, a second positioning hole 325 is vertically opened at the top of the limit block 323, and the first positioning hole 324 corresponds to the second positioning hole 325.

[0040] A positioning rod 326 is inserted into the first positioning hole 324 in a plug-in fit, and the bottom of the positioning rod 326 is inserted into the second positioning hole 325 in a plug-in fit. Furthermore, the possibility that the limit block 323 causes the connection instability of two adjacent reference units 321 due to accidental rotation is reduced.

[0041] To facilitate the removal of the positioning rod 326, magnetic materials are filled at the bottom of the reference unit 321 and the top of the positioning rod 326, and the magnetic materials at the bottom of the reference unit 321 and the top of the positioning rod 326 attract each other. When it is necessary to remove the positioning rod 326, the positioning rod 326 is removed by the suction force between the reference unit 321 and the positioning rod 326, so as to improve the convenience of removing the positioning rod 326.

[0042] The top of the mounting base 31 is provided with a guiding groove 327, a limiting groove 328 and a first positioning hole 324 that are the same as those of the reference unit 321.

[0043] The clamping member 33 includes a telescopic rod 331 and a clamping jaw 332.

[0044] One end of the telescopic rod 331 away from the clamping jaw 332 is fixedly installed with a rotating cylinder 333. The rotating cylinder 333 is rotatably sleeved on the reference rod 32, so as to improve the working range of the telescopic rod 331. To facilitate fixing the rotating cylinder 333 on the reference rod 32, a limiting bolt 3331 is threadedly connected to the side wall of the rotating cylinder 333, and the end of the limiting bolt 3331 abuts against the side wall of the reference rod 32.

[0045] The telescopic rod 331 includes a fixed rod 3311, a sliding cylinder 3312 and a spring.

[0046] One end of the fixed rod 3311 is fixedly installed on the outer peripheral surface of the rotating cylinder 333. The sliding cylinder 3312 is slidably sleeved on the fixed rod 3311. By sliding the sliding cylinder 3312 on the fixed rod 3311, the overall length of the telescopic rod 331 is adjusted. The clamping jaw 332 is fixedly installed at one end of the telescopic cylinder away from the rotating cylinder 333.

[0047] To prevent the fixed rod 3311 and the rotating cylinder 333 from rotating relative to each other, the longitudinal cross-sections of the fixed rod 3311 and the rotating cylinder 333 are both polygonal. In the embodiment of the present application, the longitudinal cross-sections of the fixed rod 3311 and the rotating cylinder 333 are both quadrilateral.

[0048] A fixing bolt 3313 is threadedly connected to the side wall of the sliding cylinder 3312, and the end of the fixing bolt 3313 abuts against the fixed rod 3311.

[0049] The spring is located inside the sliding cylinder 3312, and one end of the spring abuts against the sliding cylinder 3312, and the other end of the spring abuts against the end of the fixed rod 3311. The clamping jaw 332 is pressed against the conveying pipeline 5 by the elastic force of the spring. Then, the fixing bolt 3313 is tightened against the fixed rod 3311, so as to complete the fixation of the sliding cylinder 3312 and the fixed rod 3311 and improve the clamping stability of the conveying pipeline 5.

[0050] The jaw 332 includes two hoop clamps 3321, one of the hoop clamps 3321 is detachably and fixedly installed at the end of the sliding cylinder 3312, and the two hoop clamps 3321 are connected by bolts.

[0051] When clamping the conveying pipeline 5, the hoop clamp 3321 installed on the sliding cylinder 3312 abuts against the conveying pipeline 5 under the elastic force of the spring. Then, the two hoop clamps 3321 clamp the conveying pipeline 5, thereby completing the clamping and fixing of the conveying pipeline 5 and improving the convenience of clamping the conveying pipeline 5.

[0052] The implementation principle of the frame for an underwater pelletizer in an embodiment of the present application is as follows: when it is necessary to clamp the conveying pipeline 5, according to the height of the conveying pipeline 5, different numbers of reference units 321 are selected and the reference units 321 are placed vertically. The limiting block 323 is inserted into the adjacent guide groove 327, and the reference unit 321 is rotated so that the limiting block 323 is placed in the limiting groove 328. Then, the positioning rod 326 is inserted into the first positioning hole 324 and the second positioning hole 325 to complete the assembly of the reference unit 321. Then, the rotating cylinder 333 is sleeved on the reference rod 32, and the rotating cylinder 333 is rotated on the reference rod 32 according to the layout position of the conveying pipeline 5. Then, hoop clamps 3321 of different models are selected according to different conveying pipelines 5, and the hoop clamps 3321 of the jaw 332 abut against the conveying pipeline 5 under the elastic force of the spring. The conveying pipeline 5 is clamped by the two hoop clamps 3321. Then, the fixing bolts 3313 and the limiting bolts 3331 are tightened to complete the clamping of the conveying pipeline 5 and improve the adaptability to different conveying pipelines 5.

[0053] The above are all 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.
