Description

Technical Field

[0001] The invention relates to the field of plastic processing and preparation, in particular to a foam plastic processing and stirring device. Background Art

[0002] When preparing foam plastic materials, the materials need to be added to a mixing barrel, and then a stirring device is used to stir the materials in the mixing tank to mix the materials in the mixing tank evenly. During the stirring process, the materials in the stirring device will be relatively viscous and prone to adhesion, and then will adhere to the inner wall of the stirring device during the stirring process, resulting in insufficient stirring, reduced production efficiency, and making it difficult to clean the inner wall of the stirring device.

[0003] For this purpose, there is a foam plastic stirring device with patent announcement number CN214238961U for solving the above problems. However, the device has the following defects when in use, such as: when the scraper assembly needs to be taken out of the mixing barrel, the cover plate, motor, rotating shaft, stirring rod and scraper assembly need to be taken out of the mixing barrel at the same time, and then the scraper assembly can be disassembled or installed and replaced from the cross bar, which increases the difficulty coefficient and labor intensity of its operation and is not conducive to improving production efficiency. The fundamental reason for the above situation is: when the screw slides out of the mounting hole, the spring stretches and pushes the insertion rod to move the scraper outward through the pressure ball, and the inner wall of the mixing barrel will resist the scraper, thereby causing the insertion rod to be unable to slide out of the insertion hole, which indirectly causes the scraper assembly to be unable to be removed from the cross bar, and then the aforementioned several components need to be pulled out of the mixing barrel before the side wall of the mixing barrel resists the scraper and affects the insertion rod from sliding out of the insertion hole. Summary of the invention

[0004] The purpose of the present invention is to provide a foam plastic processing stirring device.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A foam plastic processing and stirring device comprises a barrel body, wherein a motor is arranged on the top cover plate of the barrel body, and the output shaft of the motor extends into the barrel body and is equipped with a plurality of stirring rods:

[0007] The upper and lower ends of the output shaft in the barrel body are fixed with sleeves by bolts, wherein cross bars are provided on both sides of the sleeve, and a scraper corresponding to the cross bar is vertically provided on the inner wall of the barrel body, and studs corresponding to the cross bar are provided on the upper and lower ends of one side of the scraper, wherein a mounting hole is provided at the end of the stud, and the stud is connected to the corresponding end of the cross bar through a screw tube, and U-shaped notches are provided on the upper and lower side walls of the screw tube end on the same side of the cross bar, and a sliding channel connecting the upper and lower groups of U-shaped notches is vertically provided on the stud, wherein a connecting channel connected to the mounting hole is provided on the side wall of the sliding channel, and fixed channels are also provided on the side walls of the sliding channel on the upper and lower sides of the connecting channel, and a clamping plate with two ends passing through the corresponding U-shaped notches is provided in the sliding channel, wherein a positioning rod passing through the connecting channel and embedded in the corresponding mounting hole is provided on one side wall of the clamping plate, and a spring connected to the side walls of the clamping plate on the upper and lower sides of the positioning rod is provided in the fixed channel.

[0008] As a preferred solution, the outer arc wall of the spiral tube is a smooth structure, wherein an outer wall of the end of the cross rod located in the opening of the spiral tube is provided with an external thread screwed thereto.

[0009] As a preferred solution, the stud is screwed and fixed to the spiral tube, wherein the length of the stud is not less than the length of the spiral tube.

[0010] As a preferred solution, the vertical cross-section of the mounting hole is a polygon, wherein the size of the positioning rod is adapted to the size of the mounting hole.

[0011] As a preferred solution, the number of scrapers is at least two groups, one end of the scraper is set in contact with the inner wall of the barrel body and multiple groups of arc-shaped notches are evenly arranged, wherein the multiple groups of arc-shaped notches are arranged side by side on the scraper, and the corresponding arc-shaped notches on two adjacent groups of scrapers are staggered up and down.

[0012] As a preferred solution, the stirring rod is arranged in a circular opening formed between the multiple groups of scrapers.

[0013] As a preferred solution, the width of the sliding channel is greater than the sum of the depth of the U-shaped notch and the thickness of the clamping plate.

[0014] The beneficial effect of the present invention is that when the output shaft drives the stirring rod to stir and mix the materials in the barrel body, it will also drive the scraper to scrape the inner wall of the barrel body through the cross bar to prevent the inner wall from adhering to the materials. When the scraper needs to be removed for replacement, the barrel body is entered through the manhole opened on the cover plate. At this time, it is only necessary to pull the card plate to move in the sliding channel toward the output shaft, wherein the card plate stretches the spring and drives the positioning rod to slide out of the installation hole, and the upper and lower ends of the card plate slide out of the U-shaped notch so that it will not get stuck on the side wall of the U-shaped notch. At this time, the screw tube can be rotated to separate it from the end of the cross bar and completely sheathed on the stud, so that the stud and the screw tube can be separated from the cross bar and the scraper can be indirectly separated from the cross bar. At this time, the scraper, the stud and the screw tube can be lifted up to be pulled out from the manhole on the cover plate, wherein the cross bar will not affect the removal of the scraper, and the installation steps are just the opposite, so that the scraper and other components on the cross bar can be installed, disassembled or replaced without having to pull out a series of components such as the output shaft, the stirring rod and the cross bar from the barrel body.

DETAILED DESCRIPTION

[0019] The following are examples and the attached Figure 1-3 , the technical solution of the present invention is further specifically described.

[0020] A foam plastic processing and stirring device comprises a barrel body 1, wherein a motor 2 is arranged on the top cover plate of the barrel body 1, and an output shaft 3 of the motor 2 extends into the barrel body 1 and is equipped with a plurality of stirring rods 4:

[0021] The upper and lower ends of the output shaft 3 in the barrel body 1 are fixed with sleeves 5 by bolts, wherein cross bars 6 are arranged on both sides of the sleeve 5, and a scraper 7 corresponding to the cross bar 6 is vertically arranged on the inner wall of the barrel body 1, and the upper and lower ends of one side of the scraper 7 are arranged with studs 8 corresponding to the cross bar 6, wherein the end of the stud 8 is provided with a mounting hole 9, and the stud 8 is connected to the end of the corresponding cross bar 6 by a screw tube 10;

[0022] like Figure 1 , 2 As shown, U-shaped notches 11 are provided on the upper and lower side walls of the end of the screw tube 10 on the same side of the cross bar 6, and a sliding channel 12 connecting the upper and lower groups of U-shaped notches 11 is vertically provided on the stud 8, wherein a connecting channel 13 connected to the mounting hole 9 is provided on the side wall of the sliding channel 12, and fixed channels 14 are also provided on the side walls of the sliding channel 12 on the upper and lower sides of the connecting channel 13, and a clamping plate 15 with two ends passing through the corresponding U-shaped notches 11 is provided in the sliding channel 12, wherein a positioning rod 16 passing through the connecting channel 13 and embedded in the corresponding mounting hole 9 is provided on one side wall of the clamping plate 15, and a spring 17 connected to the side walls of the clamping plate 15 on the upper and lower sides of the positioning rod 16 is provided in the fixed channel 14.

[0023] As a preferred solution, the outer arc wall of the spiral tube 10 is a smooth structure, wherein the outer side wall at the end of the cross bar 6 located in the opening of the spiral tube 10 is provided with an external thread screwed thereto.

[0024] In this embodiment, the stud 8 is screwed and fixed with the screw tube 10, wherein the length of the stud 8 is not less than the length of the screw tube 10. When the clamping plate 15 slides out of the U-shaped notch 11, the screw tube 10 can be rotated to rotate onto the stud 8 and separate from the end of the cross bar 6, thereby facilitating the scraper 7 to be separated from the cross bar 6 and taken out of the barrel body 1.

[0025] In this embodiment, the vertical cross-section of the mounting hole 9 is polygonal, wherein the size of the positioning rod 16 is adapted to the size of the mounting hole 9 .

[0026] In this embodiment, the number of scrapers 7 is at least two groups, one end of the scraper 7 is arranged in contact with the inner wall of the barrel body 1 and multiple groups of arc-shaped notches are evenly arranged, wherein the multiple groups of arc-shaped notches are arranged vertically and side by side on the scraper 7, and the corresponding arc-shaped notches on two adjacent groups of scrapers 7 are staggered vertically. The friction between the scraper 7 and the inner wall of the barrel body 1 is reduced by the arc-shaped notches, so that the scraper 7 is easy to slide on the inner wall of the barrel body 1, and the arc-shaped notches on the two adjacent groups of scrapers 7 are staggered vertically, so that the two adjacent groups of scrapers can cover the entire inner wall of the barrel body 1 when rotating.

[0027] In this embodiment, the stirring rod 4 is arranged in a circular opening formed between the plurality of scraper groups 7 .

[0028] In this embodiment, the width of the sliding channel 12 is greater than the sum of the depth of the U-shaped notch 11 and the thickness of the clamping plate 15 .

[0029] The method of use of the present invention: Figure 2As shown, the spring 17 contracts and pulls the card plate 15 to move, wherein the card plate 15 drives the positioning rod 16 to slide out of the connecting channel 13 and embed into the mounting hole 9, and at the same time, the upper and lower ends of the card plate 15 slide into the corresponding U-shaped notch 11. In the above process, the card plate 15 is pulled by the contracted spring 17 to slide into the U-shaped notch 11 to prevent it from moving, and at the same time, the sliding channel 12 abuts against the card plate 15, wherein the two ends of the card plate 15 abut against the U-shaped notch 11, thereby effectively preventing the screw tube 10 from rotating on the stud 8 and the end of the cross bar 6, so that the screw tube 10 is always screwed with the stud 8 and the end of the cross bar 6, so as to indirectly prevent the scraper 7 from separating from the cross bar 6, thereby improving the stability between the scraper 7 and the cross bar 6;

[0030] Then, when the output shaft 3 drives the stirring rod 4 to stir and mix the materials in the barrel body 1, it will also drive the scraper 7 through the cross bar 6 to scrape the inner wall of the barrel body 1 to prevent the materials from adhering to the inner wall. When it is necessary to remove the scraper 7 for replacement, enter the barrel body 1 through the manhole opened on the cover plate. At this time, it is only necessary to pull the card plate 15 in the sliding channel 12 to move toward the output shaft 3, wherein the card plate 15 stretches the spring 17 and drives the positioning rod 16 to slide out of the mounting hole 9, and the upper and lower ends of the card plate 15 slide out of the U-shaped notch 11 so that it will not get stuck on the side wall of the U-shaped notch 11. At this time, the screw tube 10 can be rotated to separate it from the end of the cross bar 6 and completely sheathed on the stud 8. The scraper 7, the stud 8 and the screw tube 10 can be lifted upwards to be pulled out from the manhole on the cover plate, wherein the cross bar 6 will not affect the removal of the scraper 7, and the installation steps are just the opposite, so that the scraper 7 and other components on the cross bar 6 can be installed, disassembled or replaced without pulling out a series of components such as the output shaft 3, the stirring rod 4 and the cross bar 6 from the barrel body 1. During operation, if the sliding channel 12 on the back of the card plate 15 is filled with materials, it can be poked out of the sliding channel 12 by a tool, so that it will not affect the movement of the card plate 15 in the sliding channel 12.

[0031] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
