Description

Technical Field

[0002] The ear thermometer is a disposable accessory designed for use with an ear thermometer (an infrared ear thermometer). Its primary function is to ensure hygienic and accurate temperature measurement. The specially designed transparent portion of the ear thermometer reduces infrared scatter, enabling the thermometer to quickly capture the infrared spectrum radiated by the eardrum (near the hypothalamus, the body's temperature center), resulting in results closer to core body temperature.

[0003] Ear thermometers are made of biocompatible materials through precision injection molding / thermocompression molding. Their transparency directly impacts the accuracy of the thermometer's measurements. Factors that affect material transparency include: Ineffective dust isolation during the mixing process can lead to foreign matter contaminating the highly transparent raw material, affecting product clarity; and uneven mixing (e.g., decreased stirring efficiency) can affect transparency consistency.

[0017] As described above, the raw material mixing device for producing high-transparency ear thermometers of the present invention has the following beneficial effects: The present invention provides sealing covers at both ends of the mixing drum, so that the interior of the mixing drum is in a sealed state, thereby preventing impurities from being mixed into the raw materials when they are mixed. At the same time, two groups of stirring member support parts are provided inside the mixing drum to support the stirring blade connecting rod, and stirring blades are provided on the outer surface of the stirring blade connecting rod. When the mixing drum rotates and stirs, the stirring member support parts will vibrate under the action of the centrifugal force of the rotation, the impact force of the raw materials and gravity, causing the stirring parts to vibrate inside the mixing drum, thereby improving the disorder during stirring and improving the uniformity of stirring. This device achieves the effect of improving the clarity of the product from the two aspects of sealing and stirring uniformity.

[0018] The present invention provides a vibration support ring, and a support inner ring is provided at the axis of the vibration support ring, and the vibration support ring and the support inner ring are connected together by a plurality of elastic support rods. When the mixing drum rotates, the support inner ring compresses the elastic support rods in the corresponding direction under the influence of centrifugal force, impact force and gravity, so that the stirring components are offset and tilted in the corresponding direction, which increases the dimension of stirring and further improves the uniformity of raw material mixing.

[0019] The present invention provides a rotatable rotating stirring blade on the outer surface of the stirring blade connecting rod, and provides fixed stirring blades on both sides of the rotating stirring blade on the outer surface of the stirring blade connecting rod. When the mixing drum rotates to stir the raw materials, the rotating stirring blade will rotate under the action of centrifugal force and impact force, thereby generating an angle difference between the rotating stirring blade and the fixed stirring blade, thereby improving the stirring area and stirring uniformity.

[0020] The present invention arranges permanent magnets on the outer surface of the rotating stirring blades, and arranges a number of driving electromagnetic groups equidistantly distributed along the inner wall of the groove in the top groove of the mixer support seat. The rotating stirring blades are driven to rotate by the attraction and / or repulsion between the driving electromagnetic groups and the permanent magnets, thereby achieving skewed rotation of the mixing drum and the rotating stirring blades, and performing multi-dimensional stirring on the raw materials inside the mixing drum to improve the uniformity of the raw material mixing.

[0021] The present invention arranges fixed stirring blades on both sides of the rotating stirring blade, and makes the edges of the fixed stirring blade fit into the edge of the rotating stirring blade. When the rotating stirring blade is driven by the permanent magnet to rotate, the edges of the rotating stirring blade and the fixed stirring blade will generate shear force, thereby shearing and crushing the raw materials in the mixing drum, so that the particles of the raw materials are finer, more uniform, and easier to be heated and melted, thereby achieving the effect of improving the working efficiency of the injection molding machine.

[0022] The present invention provides a rotating support groove on the top of the support base, and provides an angle driving gear at the bottom of the rotating support groove to be driven by a motor, and at the same time provides an arc-shaped base at the bottom of the mixer support seat, so that the driven tooth groove at the bottom of the arc-shaped base is engaged with the angle driving gear. The angle driving gear is driven by the motor to change the inclination angle of the mixer support seat. By repeatedly adjusting the angle of the mixer support seat, the mixing drum can be shaken, thereby achieving the effect of further improving the uniform mixing of the raw materials.

[0023] At the same time, openings are provided at both ends of the mixing drum and are sealed by sealing covers. When loading and unloading, the mixing drum can be tilted in corresponding directions to facilitate loading and unloading.

[0024] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value. BRIEF DESCRIPTION OF THE DRAWINGS

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0040] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the present invention provides a raw material mixing device for producing high-transparency ear thermometers. The device comprises a base mechanism 1, which supports the entire device and maintains its stability. A relay support mechanism 2 is supported on the base mechanism 1, and a mixing mechanism 3 is disposed on the relay support mechanism 2. The relay support mechanism 2 can drive the mixing mechanism 3 to rotate through friction or gear meshing force, thereby mixing the raw materials within the mixing mechanism 3.

[0041] Specifically, the relay support mechanism 2 includes a mixer support seat 21. The top of the mixer support seat 21 is provided with a groove, and the mixing mechanism 3 is installed in the groove, and the columnar mixing mechanism 3 is limited by the groove. Roller support members 24 are provided on both sides of the groove at the top of the mixer support seat 21. The roller support members 24 are connected to the top of the mixer support seat 21 by bolts, so that the roller support members 24 are detachable. Roller limiters 25 are provided on the inner wall of the groove at the top of the mixer support seat 21 to support both sides of the mixing mechanism 3. Four rolling drive rollers 26 distributed in a rectangular shape are provided at the bottom of the groove at the top of the mixer support seat 21. Any one or more of the four rolling drive rollers 26 are driven by a motor located inside the mixer support seat 21. When the rolling drive rollers 26 rotate, they can drive the mixing drum 31 to rotate by friction or meshing force, thereby achieving mixing of the raw materials inside the mixing mechanism 3.

[0042] The mixing mechanism 3 includes a mixing drum 31, which is a hollow cylinder with tapered ends. The outer surface of the mixing drum 31 is provided with a limiting chute 32 and a support slip ring 33. The limiting chute 32 and the support slip ring 33 cooperate with the drum support 24 and the drum limiter 25 respectively to support and limit the mixing drum 31, so that the mixing drum 31 will not deviate or fall off when it rotates. Both ends of the mixing drum 31 are provided with openings, one of which is a feed port and the other is a discharge port. The openings at both ends of the mixing drum 31 are provided with openable and closable sealing covers 34, which can prevent the raw materials from being stirred and spilled when the raw materials are mixed, and prevent external impurities from entering the interior of the mixing drum 31 to contaminate the raw materials and reduce the clarity of the product.

[0043] Agitator support portions 35 are provided at both ends of the mixing drum 31, and are arranged coaxially with the mixing drum 31. The axis of the two agitator support portions 35 jointly supports a stirring blade connecting rod 36, and the outer surface of the stirring blade connecting rod 36 is provided with a stirring component. When the mixing drum 31 is driven by the rolling drive roller 26 to rotate, the stirring component pushes the raw materials to move within the mixing drum 31, and under the action of centrifugal force and gravity, the raw materials are stirred and mixed with each other. The agitator support portions 35 can pull the stirring blade connecting rod 36 to vibrate, thereby causing the stirring component to deviate, thereby improving the efficiency and effectiveness of the raw material mixing.

[0044] like Figure 8 and Figure 9 As shown, in some embodiments of the present invention, all stirring member support portions 35 include a vibration support ring 351. A fixed support rod 352 is provided on the outer surface of the vibration support ring 351. The other end of the fixed support rod 352 is fixedly connected to the inner wall of the mixing drum 31. Thus, the vibration support ring 351 is fixed inside the mixing drum 31 coaxially with the mixing drum 31.

[0045] The axis of the vibration support ring 351 is provided with an inner support ring 353. The end of the stirring blade connecting rod 36 passes through the axis of the inner support ring 353 and is fixed, so that the stirring blade connecting rod 36 is fixed to the axis inside the mixing drum 31. A plurality of elastic support rods 354 are provided between the vibration support ring 351 and the inner support ring 353. The elastic support rods 354 are retractable. When the inner support ring 353 is subjected to pressure, the inner support ring 353 will squeeze the elastic support rods 354 in the corresponding direction and stretch the elastic support rods 354 on the other side, thereby causing the inner support ring 353 to deviate, thereby causing the stirring component to vibrate disorderly, thereby improving the stirring effect on the raw materials.

[0046] like Figure 10 As shown, in some embodiments, each elastic support rod 354 of the present invention includes a first support rod 3541 and a second support rod 3542. The first support rod 3541 and the second support rod 3542 are connected to the interior of the vibration support ring 351 and the outer surface of the inner support ring 353, respectively. One end of the second support rod 3542 is inserted into the interior of the first support rod 3541 and is slidable within the interior of the first support rod 3541. When the second support rod 3542 is compressed, it slides toward the interior of the first support rod 3541, thereby achieving the telescopic movement of the first support rod 3541. An elastic member 3543 is provided within the first support rod 3541 to support the end of the second support rod 3542. When the pressure on the second support rod 3542 is removed, the elastic member 3543 returns the second support rod 3542 to its initial state under the action of the elastic force. The combined force of the multiple second support rods 3542 also returns the inner support ring 353 to the axis of the mixing drum 31.

[0047] like Figure 6 、 Figure 7 and Figure 8As shown, in some embodiments, the stirring component of the present invention includes a rotating stirring blade 37 and a fixed stirring blade 39. The rotating stirring blade 37 and the fixed stirring blade 39 are both mounted on the outer surface of the stirring blade connecting rod 36, and the rotating stirring blade 37 can rotate with the stirring blade connecting rod 36 as the rotating axis. When the mixing drum 31 rotates to mix the raw materials, the rotating rotating stirring blade 37 will rotate under the action of gravity and the impact force of the raw materials. As a result, the angle of the rotating stirring blade 37 and the fixed stirring blade 39 changes, thereby increasing the angle diversity when mixing the raw materials and improving the diversity of raw material mixing.

[0048] There are two fixed stirring blades 39, one on each side of the rotating stirring blade 37. The edges of the fixed stirring blades 39 collide with the edges of the rotating stirring blades 37, and the contact is sharp. When the rotating stirring blades 37 rotate, the edges of the rotating stirring blades 37 and the fixed stirring blades 39 contact each other, creating a shear force that cuts the raw material, making it finer and improving mixing uniformity. The refined raw material can improve the efficiency of the injection molding machine.

[0049] like Figure 5-Figure 8 As shown, in some embodiments, a plurality of drive electromagnetic groups 27 are equidistantly arranged along the inner wall of the groove at the top of the mixer support seat 21 of the present invention, and each drive electromagnetic group 27 can replace the magnetic pole. The outer end of the rotating stirring blade 37 is provided with a permanent magnet 38, and the positions of the drive electromagnetic group 27 and the permanent magnet 38 are adapted. The drive electromagnetic group 27 drives the rotating stirring blade 37 to rotate by switching the magnetic poles to exert a force of attraction and / or repulsion on the permanent magnet 38, and its driving principle is the same as the working principle of a brushless motor. This makes the rotation of the rotating stirring blade 37 more stable and controllable, thereby improving the controllability of raw material mixing. The rotating stirring blade 37 driven by magnetic force has stronger power, making the shear force generated between the rotating stirring blade 37 and the fixed stirring blade 39 more stable. When the shear force generated by the rotating stirring blade 37 is insufficient to shear part of the raw materials, the raw materials stuck between the rotating stirring blade 37 and the fixed stirring blade 39 will fall off under the action of the vibration force of the stirring member support 35, which can prevent the rotating stirring blade 37 from being stuck. At the same time, the rotating stirring blades 37 can break up lumps in the raw materials, and cooperate with the vibration of the stirring member support part 35 to better mix the raw materials.

[0050] like Figure 7 and Figure 11As shown, in some embodiments, the rotating stirring blade 37 of the present invention includes two support bearings 371, both of which are sleeved on the outer surface of the stirring blade connecting rod 36, and the support bearings 371 are rotatable. The outer surfaces of the two support bearings 371 jointly support a plurality of U-shaped connecting frames 372, and the U-shaped connecting frames 372 are arranged along the circumference of the outer contour of the support bearings 371. Permanent magnets 38 are arranged on the outer surface of the U-shaped connecting frames 372, so as to drive the support bearings 371 to rotate by applying force to the U-shaped connecting frames 372. The interior of the U-shaped connecting frames 372 is provided with a plurality of first stirring blades 373 extending toward the support bearings 371. The first stirring blades 373 are arranged at an angle, and the inclination direction can be arranged in a disordered manner to improve the uniformity of the raw material mixing. When the support bearings 371 rotate, the first stirring blades 373 will push the raw materials to move. After being subjected to the force, the raw materials move in multiple directions and mix with each other under the action of gravity.

[0051] Each fixed stirring blade 39 includes two fixed support rings 391, and the two fixed support rings 391 are fixed to the outer surface of the stirring blade connecting rod 36. A plurality of fixed connecting frames 392 are supported between the two fixed support rings 391. The profile of the fixed connecting frame 392 is adapted to the profile of the mixing drum 31. The inner wall of the fixed connecting frame 392 is provided with a plurality of second stirring blades 393 extending in the direction of the fixed support rings 391. The second stirring blades 393 are used to push the raw materials when the mixing drum 31 rotates, thereby achieving the mixing of the raw materials. The side of the fixed connecting frame 392 is fitted with the side of the U-shaped connecting frame 372, and the fitting point between the two is a sharp edge. When the U-shaped connecting frame 372 is driven to rotate, the U-shaped connecting frame 372 forms a shearing force with the edge of the fixed connecting frame 392 through the power of rotation to shear and crush the raw materials.

[0052] like Figure 12 As shown, in some embodiments of the present invention, a hollow groove 3721 is provided inside the side of all U-shaped connecting frames 372, and the interior of the hollow groove 3721 is filled with a fluid body 3722. The filling amount of the fluid body 3722 does not exceed half of the volume of the hollow groove 3721. When the U-shaped connecting frame 372 rotates, the fluid body 3722 will sway inside the hollow groove 3721 under the action of centrifugal force, thereby shifting the center of gravity of the support bearing 371. The power of the shift of the center of gravity of the support bearing 371 will directly act on the stirring member support portion 35, thereby making the vibration of the stirring member support portion 35 more frequent and disordered.

[0053] like Figure 5As shown, in some embodiments, each roller support member 24 of the present invention includes a support bracket 241, and the cross-section of the support bracket 241 is L-shaped. The base of the support bracket 241 is fixed to the top of the mixer support seat 21 by bolts. An extension rod 242 is provided on the side of the support bracket 241 facing the mixing drum 31, and a roller 243 is provided on the end of the extension rod 242 facing the mixing drum 31. The roller 243 is located in the inner groove in the middle of the limiting chute 32. The extension rod 242 is located above the axis of the mixing drum 31, so that the extension rod 242 cooperates with the inner groove on the limiting chute 32 to prevent the mixing drum 31 from detaching from the top of the mixer support seat 21. The roller 243 is used to reduce the friction between the extension rod 242 and the limiting chute 32, thereby improving the service life of the equipment and the flexibility of the rotation of the mixing drum 31.

[0054] All roller stoppers 25 include a roller support plate 251, with a limit groove 252 defined on the side of the roller support plate 251 facing the mixing roller 31. A support ring 33 is positioned within the limit groove 252 and is restrained by the limit groove 252 to prevent displacement. This prevents the mixing roller 31 from moving horizontally above the mixer support base 21.

[0055] like Figure 3 As shown, in some embodiments, the base mechanism 1 of the present invention includes a support base 11, with a rotation support groove 12 disposed at the top of the support base 11. The interior of the rotation support groove 12 has an arcuate cross-section. Articulated brackets 13 are disposed on both sides of the rotation support groove 12. The interior of the articulated brackets 13 includes a wiring channel extending into the interior of the mixer support base 21. An angle drive gear 15 is disposed at the bottom of the rotation support groove 12. The angle drive gear 15 is driven by a motor within the support base 11.

[0056] The bottom of the mixer support seat 21 is provided with an arc-shaped base 22, and the bottom of the arc-shaped base 22 is provided with a driven tooth groove 23. The arc-shaped base 22 is located inside the rotating support groove 12, and the cross-section of the arc-shaped base 22 is adapted to the cross-section of the rotating support groove 12. The two sides of the arc-shaped base 22 are respectively connected to the hinge bracket 13 for rotation, so that the arc-shaped base 22 can rotate with the connection with the hinge bracket 13 as the axis. The driven tooth groove 23 is engaged with the angle drive gear 15. When the angle drive gear 15 is driven by the motor to rotate, the arc-shaped base 22 is driven to rotate, thereby causing the angle of the mixing drum 31 to change accordingly. When the angle of the mixing drum 31 changes, the raw materials inside the mixing drum 31 will be displaced accordingly, increasing the diversity of the mixing direction, thereby improving the efficiency and uniformity of the raw material mixing.

[0057] A material unloading platform 16 is provided on the side of the rotating support tank 12 for placing containers. When the raw materials are mixed, automatic unloading can be achieved by tilting the mixing drum 31 toward the material unloading platform 16 .

[0058] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a control box 14 is provided on the side of the support base 11 , and the control box 14 is provided with an operating interface for the control circuit and a display interface for displaying data.

[0059] The motor that controls the angle drive gear 15 is connected to the control box 14. The cables that drive the motor for the rolling drive roller 26 and the electromagnetic drive assembly 27 extend through the side of the curved base 22 to the interior of the articulated bracket 13 and are connected to the control box 14. The control box 14 can control the tilt angle and tilt direction of the mixing drum 31, the rotation rate and rotation direction of the mixing drum 31, and set and control the magnetic pole switching mode of the electromagnetic drive assembly 27.

[0060] In summary, the raw material mixing device for the production of high-transparency ear thermometers of the present invention provides sealing covers 34 at both ends of the mixing drum 31, so that the interior of the mixing drum 31 is in a sealed state, thereby preventing impurities from being mixed into the raw materials when they are mixed. At the same time, two groups of stirring member support parts 35 are provided inside the mixing drum 31 to support the stirring blade connecting rod 36, and stirring blades are provided on the outer surface of the stirring blade connecting rod 36. When the mixing drum 31 rotates and stirs, the stirring member support parts 35 will vibrate under the action of the centrifugal force of the rotation, the impact force of the raw materials and the gravity, so that the stirring parts vibrate inside the mixing drum 31, thereby improving the disorder during stirring and improving the uniformity of stirring. This device achieves the effect of improving the clarity of the product from the two aspects of sealing and stirring uniformity.

[0061] The present invention sets a vibration support ring 351, sets a support inner ring 353 at the axis of the vibration support ring 351, and connects the vibration support ring 351 and the support inner ring 353 together through a plurality of elastic support rods 354. When the mixing drum 31 rotates, the support inner ring 353 compresses the elastic support rods 354 in the corresponding direction under the influence of centrifugal force, impact force and gravity, so that the stirring component is offset and tilted in the corresponding direction, which increases the dimension of stirring and further improves the uniformity of raw material mixing.

[0062] The present invention provides a rotatable rotating stirring blade 37 on the outer surface of the stirring blade connecting rod 36, and provides fixed stirring blades 39 on both sides of the rotating stirring blade 37 on the outer surface of the stirring blade connecting rod 36. When the mixing drum 31 rotates to stir the raw materials, the rotating stirring blade 37 will rotate under the action of centrifugal force and impact force, thereby generating an angle difference between the rotating stirring blade 37 and the fixed stirring blade 39, thereby improving the stirring area and stirring uniformity.

[0063] The present invention arranges a permanent magnet 38 on the outer surface of the rotating stirring blade 37, and arranges a plurality of driving electromagnetic groups 27 equidistantly distributed along the inner wall of the groove in the top groove of the mixer support seat 21. The rotating stirring blade 37 is driven to rotate by the attraction and / or repulsion between the driving electromagnetic group 27 and the permanent magnet 38, so as to realize the skewed rotation of the mixing drum 31 and the rotating stirring blade 37, and perform multi-dimensional stirring on the raw materials inside the mixing drum 31 to improve the uniformity of the raw material mixing.

[0064] The present invention provides fixed stirring blades 39 on both sides of the rotating stirring blade 37, and makes the edges of the fixed stirring blades 39 fit into the edges of the rotating stirring blades 37. When the rotating stirring blades 37 are driven to rotate by the permanent magnets 38, the edges of the rotating stirring blades 37 and the fixed stirring blades 39 will generate shear force, thereby shearing and crushing the raw materials in the mixing drum 31, so that the particles of the raw materials are finer, more uniform, and easier to be heated and melted, thereby achieving the effect of improving the working efficiency of the injection molding machine.

[0065] The present invention provides a rotating support groove 12 on the top of the support base 11, and provides an angle driving gear 15 at the bottom of the rotating support groove 12 to be driven by a motor, and at the same time provides an arc-shaped base 22 at the bottom of the mixer support seat 21, so that the driven tooth groove 23 at the bottom of the arc-shaped base 22 is engaged with the angle driving gear 15. The angle driving gear 15 is driven by the motor to change the inclination angle of the mixer support seat 21. By repeatedly adjusting the angle of the mixer support seat 21, the mixing drum 31 can be shaken, thereby achieving the effect of further improving the uniform mixing of the raw materials.

[0066] At the same time, both ends of the mixing drum 31 are provided with openings which are sealed by sealing covers 34. When loading and unloading, the mixing drum 31 can be tilted in corresponding directions to facilitate loading and unloading.

[0067] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
