Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, and specifically relates to a mixer for plastic processing. Background Technology

[0002] In the plastic processing process, it is often necessary to mix and stir different types and colors of plastic granules or powders to prepare a uniform raw material mixture. Generally, a mixer is used to stir and process plastic raw materials. The existing mixer top cover fixing method mostly uses bolts to fasten multiple points, which is cumbersome and time-consuming. For occasions that require frequent opening and closing of the top cover for cleaning or material replacement, it seriously affects work efficiency. Although the existing mixers are equipped with casters for easy movement, the vibration generated by the mixer during operation can easily cause the entire machine to shift or even tip over, posing a safety hazard. Therefore, we propose a mixer for plastic processing. Utility Model Content

[0003] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a plastic processing mixer, so as to solve the problems mentioned in the background art that the existing mixer top cover fixing method mostly uses bolts to fasten multiple points, which seriously affects the work efficiency, and the vibration generated by the mixer during operation can easily cause the machine to shift or even tip over, posing a safety hazard.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plastic processing mixer, comprising a shell, a control panel fixedly connected to one side of the shell, support columns fixedly connected to the four corners of the bottom of the shell, casters mounted on the bottom of the support columns, a fixing plate fixedly connected to one side of the support columns, an adjusting rod rotatably connected inside the fixing plate, a support plate fixedly connected to the bottom of the adjusting rod, a top cover mounted on the top of the shell, a handle fixedly connected to the top of the top cover, a feed pipe fixedly connected to the top of the top cover, four sets of mounting blocks fixedly connected to the surface of the top cover, a sliding groove formed on the surface of the mounting blocks, a slot formed at the top of the sliding groove, four sets of fixing structures provided on the top of the side surface of the shell, each fixing structure comprising two sets of fixing blocks, a rotating sleeve rotatably connected between the two sets of fixing blocks, fixing rods fixedly connected to both sides of the rotating sleeve, a threaded rod rotatably connected inside the rotating sleeve, a limit block fixedly connected to the bottom of the threaded rod, a knob fixedly connected to the top of the threaded rod, and a pressure plate fixedly connected to the outer side of the threaded rod.

[0005] Preferably, the surface of the fixing plate is provided with a threaded groove, the adjusting rod is rotatably connected in the threaded groove, and the universal wheel does not contact the adjusting rod.

[0006] Preferably, a rubber pad layer is provided at the bottom of the support plate.

[0007] Preferably, the surfaces of the two sets of fixing blocks are provided with a circular groove, the fixing rod is rotatably connected in the circular groove, the height of the rotating sleeve is shorter than the height of the fixing block, and the rotating sleeve is a rotatable structure between the two sets of fixing blocks.

[0008] Preferably, the surface of the rotating sleeve is provided with a second threaded groove, the threaded rod is rotatably connected in the second threaded groove, and the radius of the limiting block is larger than the radius of the threaded rod.

[0009] Preferably, the threaded rod is slidably connected in the groove, the radius of the pressure plate is equal to the radius of the slot, and the pressure plate is engaged in the slot.

[0010] Preferably, the surface of the pressure plate is provided with a rubber pad layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This plastic processing mixer features a mounting block and a fixing structure. After the rotating sleeve returns to a vertical position, simply rotating the knob drives the threaded rod and pressure plate downwards. The pressure plate then slides down the groove and finally locks tightly into the slot of the top cover mounting block. This embedded locking mechanism, combined with the elastic seal of the rubber pad layer on the pressure plate surface, forms a highly reliable locking mechanism that effectively resists vibration, centrifugal force, and the potential lifting tendency of the top cover during operation. The locking effect of the slot on the pressure plate is significantly better than simple bolt tightening, ensuring that the top cover is tightly fastened to the outer shell. The locking process can be quickly completed by one person with one hand, achieving high operational efficiency.

[0013] 2. This plastic processing mixer is equipped with an adjusting rod and support plates. By rotating the adjusting rod to raise the four support plates to their highest position, the mixer can be easily moved to any working position. By rotating the adjusting rod to lower the four support plates, the rubber pads at the bottom of the support plates provide stable support to the ground. In conjunction with the casters, this increases the contact area with the ground. The rubber pads at the bottom of the support plates significantly increase friction and effectively absorb vibration, allowing the mixer to remain stable even when rotating at high speed. This reduces the risk of displacement due to vibration during operation, greatly improving the safety and stability of the equipment. The adjustment operation is simple, and the switching between the support and movement states is quick and reliable. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 One embodiment provided by this utility model:

[0022] A plastic processing mixer includes a housing 1. A control panel 11 is fixedly connected to one side of the housing 1. Support columns 12 are fixedly connected to the four corners of the bottom of the housing 1. Casters 13 are installed at the bottom of the support columns 12. A fixing plate 14 is fixedly connected to one side of the support columns 12. An adjusting rod 15 is rotatably connected inside the fixing plate 14. A support plate 16 is fixedly connected to the bottom of the adjusting rod 15. A top cover 2 is installed on the top of the housing 1. A handle 21 is fixedly connected to the top of the top cover 2. A feed pipe 22 is fixedly connected to the top of the top cover 2. Four sets of mounting blocks 23 are fixedly connected to the surface of the top cover 2. The surfaces of the mounting blocks 23 are open. The enclosure 1 is provided with a sliding groove 24, the top of which has a slot 25. Four sets of fixing structures 3 are provided on the top side surface of the outer casing 1. Each fixing structure 3 includes two sets of fixing blocks 31, with a rotating sleeve 32 rotatably connected between the two sets of fixing blocks 31. Fixing rods 33 are fixedly connected to both sides of the rotating sleeve 32. A threaded rod 34 is rotatably connected inside the rotating sleeve 32. A limit block 35 is fixedly connected to the bottom of the threaded rod 34, and a knob 36 is fixedly connected to the top of the threaded rod 34. A pressure plate 37 is fixedly connected to the outside of the threaded rod 34. With the mounting block 23 and fixing structures 3 in place, after the rotating sleeve 32 returns to a vertical position, it only needs to be rotated... Button 36 drives threaded rod 34 and pressure plate 37 to move downwards. Pressure plate 37 then slides down along slide groove 24 and finally locks tightly into slot 25 of mounting block 23. This embedded locking mechanism, combined with the elastic seal of rubber pad layer on the surface of pressure plate 37, forms a very reliable locking mechanism that can effectively resist vibration, centrifugal force, and possible lifting tendency of top cover 2 during operation. The limiting effect of slot 25 on pressure plate 37 is significantly better than simple bolt tightening, ensuring that top cover 2 is tightly fastened to outer shell 1. The locking process can be quickly completed by one person with one hand at all four fixing points, resulting in high operational efficiency. An adjusting rod 15 and support plate 16 are provided, which can be rotated to... The adjusting rod 15 raises the four support plates 16 to their highest position, allowing the mixer to be easily moved to any working position. By rotating the adjusting rod 15, the four support plates 16 can be lowered, and the rubber pads at the bottom of the support plates 16 provide stable support to the ground. In conjunction with the casters 13, the contact area with the ground is increased. The rubber pads at the bottom of the support plates 16 significantly increase friction and effectively absorb vibration, allowing the mixer to be placed stably even when it is rotating and mixing at high speed. This reduces the risk of displacement due to vibration during operation, greatly improving the safety and stability of the equipment. The adjustment operation is simple, and the switching between the support state and the moving state is quick and reliable.

[0023] Furthermore, a threaded groove is provided on the surface of the fixed plate 14, and the adjusting rod 15 is rotatably connected in the threaded groove. The universal wheel 13 does not contact the adjusting rod 15. When the adjusting rod 15 is rotated, the self-locking and guiding characteristics of the threaded pair can accurately and stably drive the support plate 16 to rise and fall in the vertical direction, so that the support plate 16 contacts the ground. In cooperation with the universal wheel 13, the contact area with the ground is increased, thereby increasing the stability.

[0024] Furthermore, the bottom of the support plate 16 is provided with a rubber pad layer, which can increase the friction with the ground, effectively prevent the mixer from sliding and shifting due to vibration during operation in the supported state, improve safety, absorb and buffer some vibration, reduce noise transmission to the ground, and provide cushioning when in contact with the ground to prevent impact or wear caused by hard contact.

[0025] Furthermore, the surfaces of the two sets of fixing blocks 31 are provided with circular grooves, and the fixing rod 33 is rotatably connected in the circular grooves. The circular grooves provide a rotation support point for the fixing rod 33, so that the rotating sleeve 32 can rotate smoothly around the fixing rod 33 as an axis. The height of the rotating sleeve 32 is shorter than the height of the fixing block 31. The rotating sleeve 32 is a rotatable structure between the two sets of fixing blocks 31, ensuring that when the rotating sleeve 32 rotates at a certain angle, it will not interfere with the interior of the fixing block 31.

[0026] Furthermore, the surface of the rotating sleeve 32 is provided with a second threaded groove, and the threaded rod 34 is rotatably connected in the second threaded groove. The radius of the limiting block 35 is greater than the radius of the threaded rod 34. When the threaded rod 34 is rotated relative to the rotating sleeve 32, due to the self-locking characteristic of the thread, the threaded rod 34 can make precise axial movement relative to the rotating sleeve 32 while maintaining its own rotation. The radius of the limiting block 35 is greater than the radius of the threaded rod 34, and its function is to limit the position of the threaded rod 34 from being screwed out, preventing the threaded rod 34 from accidentally coming out completely from the second threaded groove.

[0027] Furthermore, the threaded rod 34 is slidably connected in the groove 24, and the radius of the pressure plate 37 is equal to the radius of the slot 25. The pressure plate 37 is engaged in the slot 25. When the pressure plate 37 is engaged in the slot 25, even if the top cover 2 is subjected to the force of the material shaking or centrifugal force during the stirring process, which attempts to lift it upward and shake it left and right, the constraint of the slot 25 on the pressure plate 37 can effectively prevent the top cover 2 from being accidentally lifted or shaken, greatly enhancing the connection strength and stability in the closed state, and also ensuring good sealing performance.

[0028] Furthermore, the surface of the pressure plate 37 is provided with a rubber pad layer, which can provide uniform and gentle contact pressure, increase the static friction between the mounting block 23 and the pressure plate 37, and further enhance the clamping effect.

[0029] Working principle: After the rotating sleeve 32 returns to the vertical position, simply rotate the knob 36 to drive the threaded rod 34 and the pressure plate 37 downwards. The pressure plate 37 then slides down along the slide groove 24 and finally locks tightly into the slot 25 of the mounting block 23. This embedded locking mechanism, combined with the elastic seal of the rubber pad layer on the surface of the pressure plate 37, forms a very reliable locking mechanism. It can effectively resist vibration, centrifugal force, and the possible lifting tendency of the top cover 2 during operation. The limiting effect of the slot 25 on the pressure plate 37 is significantly better than simple bolt tightening, ensuring that the top cover 2 is tightly fastened. On the outer casing 1, the locking process can be quickly completed by one person with one hand at all four fixing points. By rotating the adjusting rod 15, the four support plates 16 can be raised to the highest position, and the mixer can be easily pushed to any working position. By rotating the adjusting rod 15, the four support plates 16 can be lowered. The rubber pad at the bottom of the support plate 16 is firmly supported on the ground. In conjunction with the casters 13, the contact area with the ground is increased. The rubber pad at the bottom of the support plate 16 significantly increases the friction and effectively absorbs vibration, so that the mixer can be placed stably even when it is rotating and mixing at high speed.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
