Description

Technical Field

[0001] The invention relates to the technical field of building raw material mixing, in particular to a raw material mixing device for building thermal insulation materials. Background Art

[0002] Building insulation materials are materials used to reduce heat transfer inside and outside buildings. The main purpose is to improve the energy efficiency of buildings, reduce energy consumption, and provide a comfortable indoor environment. ALC boards are a type of board with good thermal insulation properties. Since they contain a large number of pores, these pores can effectively reduce heat conduction and thus play a role in insulation. However, during the current processing of ALC boards, it is difficult to maintain the uniformity of the raw material mixing process, resulting in low mixing efficiency.

[0003] After searching, the Chinese patent with publication number CN115351919B includes a mixing bracket, the top of the mixing bracket is fixedly connected to a mixing spherical shell, the top of the mixing bracket located on one side of the mixing spherical shell is fixedly connected to a driving motor, the driving shaft of the driving motor is fixedly connected to a prompting device, the side of the prompting device away from the driving motor penetrates the mixing spherical shell and extends to the inside of the mixing spherical shell, the end of the prompting device located inside the mixing spherical shell is fixedly connected to the mixing device, and the top of the mixing spherical shell is connected to the feed port; the prompting device includes: a control disk, the control disk has a circular disk structure, and a control cavity opened inside the control disk, the inner wall side of the control cavity is fixedly connected to an arc spring; in the above patent, the material movement is more intense, the mixing efficiency is higher, and the material can be broken up and transferred, and the mixing effect is better.

[0004] However, for the above-mentioned patent, the raw material mixing process takes place inside the mixing sphere shell in a closed state, which results in the personnel having to repeatedly open and close the discharging device to take out samples for observation when judging the mixing progress. The samples taken out are difficult to put back into the mixing sphere shell, making the mixing process unclear. On the other hand, when the inside of the mixing sphere shell is cleaned by the mixing device, although the inner wall of the mixing sphere shell can be effectively scraped and cleaned, the mixture of cleaning water and raw materials has high viscosity and is easy to adhere to the outer surface of the mixing device, thereby causing a decrease in the subsequent mixing quality.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0020] See also Figures 1 to 9 The present invention provides a technical solution: a raw material mixing device for building thermal insulation materials, comprising a mixing drum 1 in a fixed state and a control component on one side thereof, a mixing component arranged inside the mixing drum 1, a cleaning component arranged inside the control component, and a sampling component arranged at the bottom end of the mixing drum 1, wherein a sealing plate 11 is rotatably connected to the bottom end of the mixing drum 1, a fixed roller 12 is fixedly connected to the axis center of the upper surface of the sealing plate 11, a spline groove 13 is provided at the top end of the fixed roller 12, a discharge port 14 is penetrated at the edge of the sealing plate 11, and a threaded groove is provided on the inner contour of the discharge port 14; The mixing assembly includes a transmission mechanism for realizing power transmission and a stirring mechanism for fully mixing the raw materials. The transmission mechanism is located directly above the fixed roller 12 and is intermittently engaged with the spline groove 13. The stirring mechanism is connected to the transmission mechanism in a transmission manner. The control component includes a fixed seat 2 fixedly connected to one side of the outer contour of the mixing drum 1, the transmission mechanism includes a cross shaft 3 arranged directly above the fixed roller 12 and fixedly connected to the cleaning component, the stirring mechanism includes a cross connecting rod 4 that is penetrated and limitedly rotated and connected to the outer contour above the cross shaft 3, the cleaning component includes a fixed shaft 5 located inside the control component and fixedly connected to the control component, and the sampling component includes a positioning cylinder 6 screwed on the inner contour of the discharge port 14.

[0021] In the device, the mixing drum 1 is used as the mixing area for the ALC board raw materials. The raw materials are introduced into the mixing drum 1 and then the control component is adjusted to put the device into the working mode. At this time, the mixing component performs a homogeneous mixing operation on the raw materials in the mixing drum 1.

[0022] It should be noted that during the mixing operation, the sampling operation of the raw materials inside the mixing barrel 1 can be achieved by controlling the sampling component, thereby facilitating personnel to observe the mixing process inside the mixing barrel 1 in a closed state.

[0023] When the mixing operation is completed, the control component is adjusted to put the device in cleaning mode. At this time, the cleaning component works synchronously to release the closed state of the mixing barrel 1. At this time, the interior of the mixing barrel 1 and the mixing component are fully exposed to facilitate the cleaning operation; at the same time, when the interior of the mixing barrel 1 is scraped and cleaned, the mixed raw materials are squeezed out through the discharge port 14 to realize the discharge operation.

[0024] Among them, the fixed roller 12 realizes motion transmission and cooperates with the stirring mechanism to strengthen the shear stirring degree of the raw materials to improve the mixing quality of the device; the spline groove 13 cooperates with the transmission mechanism to realize the start and stop process of the stirring mechanism, and the sealing plate 11 cooperates with the control component to realize the start and stop process of the fixed roller 12. Embodiment 2:

[0025] See also Figure 3 This embodiment further illustrates the following on the basis of the first embodiment: A limiting groove 21 is provided on the surface of the fixed seat 2, and a fixed cylinder 22 is fixedly connected to one end of the fixed seat 2 away from the mixing cylinder 1. A retaining spring is arranged inside the limiting groove 21, and a control rod 23 is slidably connected to the inner limiting position of the limiting groove 21. The bottom end of the control rod 23 is penetrated and rotatably connected to a worm sleeve 24 driven by a motor. A worm gear 25 is rotatably connected to the bottom end of the fixed cylinder 22, and the worm gear 25 is meshed and transmission connected to one side of the worm sleeve 24, and the other side of the worm sleeve 24 is meshed and transmission connected to a worm gear 26, and the worm gear 26 is fixedly connected to the outer contour of the sealing plate 11. A guide groove 27 is provided on the surface of the fixed cylinder 22.

[0026] When it is necessary to mix the raw materials, first pour the raw materials into the mixing barrel 1, and then move the control rod 23 to make it slide inside the limit groove 21, wherein the retaining spring arranged inside the limit groove 21 can effectively clamp and limit the control rod 23 at the two ends of the limit groove 21 without the action of external force, and at this time the control rod 23 drives the worm sleeve 24 to slide synchronously and enables the worm sleeve 24 to mesh with the worm gear 26; at the same time, turn on the motor to drive the worm sleeve 24 to rotate, and at this time the worm gear 26 starts to rotate slowly synchronously, and further, the worm gear 26 drives the fixed roller 12 and the spline groove 13 to start to rotate slowly synchronously.

[0027] On the other hand, when discharging and cleaning operations are required after mixing is completed, the control rod 23 is toggled in the opposite direction so that it is clamped and restricted at the other end of the limit groove 21. At this time, the engagement between the worm sleeve 24 and the worm gear 26 is disengaged and begins to engage with the worm gear 1 25. Subsequently, the rotation of the worm sleeve 24 drives the worm gear 1 25 to start slowly rotating. The worm gear 1 25 further controls the cleaning component to start working. At this time, the mixing component extends from the inside of the mixing barrel 1 and releases the clamping transmission state with the spline groove 13. Subsequently, the cleaning component extends into the inside of the mixing barrel 1 to complete the extrusion discharging operation and the scraping cleaning operation. Embodiment three:

[0028] See also Figure 4 and Figure 5 This embodiment further illustrates the following on the basis of the second embodiment: A bevel gear 1 31 penetrates through the outer contour above the cross shaft 3 and is limited in rotation connection, a fixed gear 32 penetrates through the outer contour of the top end of the cross shaft 3 and is fixedly connected, a bevel gear 2 33 penetrates through the outer contour below the cross shaft 3 and is limited in rotation connection, a spline pin 34 matched with the spline groove 13 is fixedly connected to the bottom end of the bevel gear 2 33, an X-plate 1 35 is fixedly connected to the bottom end of the bevel gear 2 33 and the X-plate 1 35 is matched with the outer contour size of the fixed roller 12, and bevel gears 3 36 penetrate through both sides of the cross shaft 3 and are limited in rotation connection.

[0029] The positions near the ends of the cross-link 4 are penetrated by and rotatably connected with a transmission wheel 1 41, and the transmission wheel 1 41 is meshed with and transmission-connected to the fixed gear 32. The positions near the ends of the cross-link 4 are penetrated by and rotatably connected with a transmission wheel 2 42, and the transmission wheel 2 42 is meshed with and transmission-connected to the transmission wheel 1 41. The bottom end of the transmission wheel 2 42 is fixedly connected with a transmission rod 43, and the other end of the transmission rod 43 is fixedly connected with an X-plate 2 44 extending downward. A cover plate 45 is penetrated by and rotatably connected to the outer contour of the transmission wheel 2 42 near the bottom, and the area of ​​the cover plate 45 is adapted to the opening size of the mixing barrel 1.

[0030] The bottom end of the cross connecting rod 4 is fixedly connected to the upper surface of the bevel gear 1 31 , the length of the X-plate 2 44 is adapted to the depth of the mixing barrel 1 and the X-plate 2 44 and the X-plate 1 35 are staggered, and the gear ratio between the transmission wheel 1 41 and the fixed gear 32 is set to 1:4.

[0031] During the mixing operation, the worm sleeve 24 drives the worm gear 26 to rotate slowly, and the worm gear 26 further drives the fixed roller 12 and the spline groove 13 to move synchronously. At this time, the spline groove 13 and the spline pin 34 are in a clamping state, that is, the spline pin 34 and the bevel gear 2 33 start to rotate slowly synchronously, and the bevel gear 2 33 further drives the bevel gear 1 31 to move synchronously through the X plate 1 35, while the cross shaft 3 and the fixed gear 32 continue to remain in a stationary fixed state.

[0032] Subsequently, the movement of the bevel gear 31 synchronously drives the cross link 4 to rotate. At this time, the transmission wheel 41 rotates around the surface of the fixed gear 32. Since the fixed gear 32 is in a fixed state, under the meshing action of the transmission wheel 41, the transmission wheel 41 rotates synchronously while rotating around the fixed gear 32; further, since the gear ratio between the transmission wheel 41 and the fixed gear 32 is set to one to four, that is, when the transmission wheel 41 rotates one circle around the fixed gear 32, it rotates synchronously four circles.

[0033] It should be noted that the rotation of the transmission wheel 1 41 synchronously drives the transmission wheel 2 42 to rotate. Figure 5It can be seen that the transmission wheel 2 42 has the same specifications as the transmission wheel 1 41, that is, the transmission wheel 2 42 also rotates four times synchronously when the transmission wheel 1 41 rotates one time around the fixed gear 32. At this time, the rotation of the transmission wheel 2 42 further drives the transmission rod 43 and the X-plate 2 44 to rotate around the extended axis of the transmission wheel 2 42. Since the X-plate 2 44 is located inside the mixing barrel 1 at this time, the surrounding rotation of the X-plate 2 44 can further realize the stirring and mixing operation of the raw materials inside the mixing barrel 1.

[0034] Furthermore, due to the transmission effect of the X-plate 1 35, the rotation directions of the bevel gear 1 31 and the bevel gear 2 33 are opposite, that is, the rotation directions of the X-plate 1 35 and the cross-link 4 are opposite. Taking the clockwise rotation of the fixed roller 12 as an example, at this time, the X-plate 1 35 rotates synchronously clockwise to achieve the stirring of the raw materials inside the mixing barrel 1, and the cross-link 4 rotates counterclockwise and drives multiple X-plates 2 44 to rotate synchronously counterclockwise around the extended axis of the cross-link 4. At this time, the opposite rotations between the X-plate 2 44 and the X-plate 1 35 can effectively shear the raw materials inside the mixing barrel 1, thereby improving the exchange and mixing quality between the raw materials in the mixing barrel 1.

[0035] On the other hand, since the gear ratio between the transmission wheel 41 and the fixed gear 32 is set to one to four, similarly, the rotation rate of the X-plate 2 44 around the transmission wheel 2 42 is four times the rotation rate of the X-plate 2 44 around the cross connecting rod 4. At this time, the X-plate 2 44 can further accelerate the exchange rate of the raw materials inside the mixing barrel 1 between the X-plate 1 35 and the X-plate 2 44 to fully realize the shear stirring of the raw materials. At the same time, the mutual scraping between the X-plate 1 35 and the X-plate 2 44 can effectively reduce the probability of the raw materials adhering to the surfaces of the X-plate 1 35 and the X-plate 2 44, thereby improving the mixing quality of the device. Embodiment 4:

[0036] See also Figure 3 and Figure 6 This embodiment further illustrates the following on the basis of the third embodiment: The fixed shaft 5 is located inside the fixed cylinder 22 and is fixedly connected to the axis center of the upper surface of the worm gear 25. A reciprocating thread 51 is fixedly connected to the outer surface of the upper half of the fixed shaft 5. The reciprocating thread 51 is screwed to the limit block 52, and the limit block 52 is slidably connected to the outer contour of the fixed cylinder 22 through the guide groove 27. A connecting rod 1 53 and a connecting rod 2 54 are fixedly connected to the outer contour above the limit block 52, and the angle between the connecting rod 1 53 and the connecting rod 2 54 is fixed to ninety degrees. The bottom of the connecting rod 1 53 away from the limit block 52 is fixedly connected to the top of the cross shaft 3, and the end of the connecting rod 2 54 away from the limit block 52 is penetrated and fixedly connected to the fixed shaft 2 55. The bottom end of the fixed shaft 2 55 is fixedly connected to a cleaning plate 56, and the area of ​​the cleaning plate 56 is adapted to the inner contour size of the mixing cylinder 1. A through groove adapted to the size of the fixed roller 12 is provided at the axis center of the cleaning plate 56.

[0037] When cleaning is required after mixing is completed, the worm sleeve 24 is meshed with the worm gear 25 by toggling the control rod 23. At this time, the worm gear 25 drives the fixed shaft 5 and the reciprocating thread 51 to rotate slowly and synchronously, and the limit block 52 tends to rotate synchronously. However, since the fixed cylinder 22 and the guide groove 27 are in a fixed state, the movement of the limit block 52 is restricted and guided by the guide groove 27.

[0038] Depend on Figure 6 It can be seen that the four corners of the guide groove 27 are marked as point A, B, C and D respectively, and the initial position of the limit block 52 is set at point A. At this time, the mixing assembly is located inside the mixing barrel 1 and performs mixing operations. When the worm sleeve 24 is engaged with the worm wheel 25, the synchronous rotation of the reciprocating thread 51 causes the limit block 52 to start rising under the limiting action of the guide groove 27. At this time, the limit block 52 moves from point A to point B; when the limit block 52 moves to point B, the mixing assembly extends from the inside of the mixing barrel 1. At this time, the cover plate 45 releases the blocking and closure of the mixing barrel 1 and causes the inside of the mixing barrel 1 and the stirring mechanism to be fully exposed. Subsequently, the continued rotation of the reciprocating thread 51 causes the limit block 52 to move from point B to point C under the limiting action of the guide groove 27.

[0039] During this process, connecting rod 1 53 and connecting rod 2 54 deflect synchronously, connecting rod 1 53 further drives the mixing assembly as a whole to deviate from directly above the mixing drum 1, and connecting rod 2 54 drives fixed shaft 2 55 and cleaning plate 56 to move synchronously. Since the angle between connecting rod 1 53 and connecting rod 2 54 is set to ninety degrees, that is, when the limit block 52 moves to point C, fixed shaft 2 55 and cleaning plate 56 are just located directly above the mixing drum 1; then the continued rotation of the reciprocating thread 51 causes the limit block 52 to start moving from point C to point D under the restriction of the guide groove 27. At this time, the cleaning plate 56 extends into the interior of the mixing drum 1 and continuously squeezes the mixed raw materials to discharge them from the discharge port 14 to realize the discharging operation. At the same time, the cleaning plate 56 scrapes the inner wall of the mixing drum 1 and the outer surface of the fixed roller 12 to realize the cleaning operation of the interior of the mixing drum 1.

[0040] It should be noted that, due to the thread setting of the reciprocating thread 51, the limit block 52 can naturally rise after being obstructed when moving to point D, that is, the cleaning plate 56 can automatically extend and disengage from the mixing barrel 1 after completing the cleaning and discharging operations inside the mixing barrel 1. When the limit block 52 returns to point C again, the motor is adjusted to control the worm sleeve 24 to rotate in the opposite direction to realize the reset process of the limit block 52 from point C to point B. When the limit block 52 is reset to point B, the mixing assembly is re-located directly above the mixing barrel 1. At this time, the raw materials are poured and added. Subsequently, the limit block 52 is reset from point B to point A under the drive of the reciprocating thread 51, and the cover plate 45 completes the shielding and closure of the mixing barrel 1 again. Embodiment five:

[0041] See also Figure 7 and Figure 8 This embodiment further illustrates the following based on the fourth embodiment: A blocking plug 61 is slidably connected to the top end of the positioning cylinder 6, and a boss 62 is fixedly connected to the bottom end of the blocking plug 61. A connecting shaft 63 is fixedly connected to the bottom end of the boss 62, and the connecting shaft 63 passes through the bottom end of the positioning cylinder 6 and extends outward. A sliding sleeve 64 passes through and is slidably connected to the outer contour of the connecting shaft 63.

[0042] Extension parts are provided on both sides of the positioning cylinder 6 and are connected to the interior of the positioning cylinder 6 . A return spring 65 extending inward is fixedly connected to the inner contour of the extension part of the positioning cylinder 6 . A latch 66 is fixedly connected to one end of the return spring 65 pointing to the interior of the positioning cylinder 6 .

[0043] It should be noted that during the mixing operation, if it is necessary to judge the mixing progress of the raw materials inside the mixing cylinder 1 in a closed state, sampling and observation operations can be achieved by pushing the connecting shaft 63. In the initial state, the latch 66 is against the outer contour of the middle section of the connecting shaft 63, and the boss 62 is located above the latch 66. At this time, the lower surface of the boss 62 is engaged with the upper surface of the latch 66, and the connecting shaft 63 cannot move downward. When the connecting shaft 63 is pushed, the sleeve 64 moves upward synchronously and squeezes the latch 66 to shrink it back into the extended portion of the positioning cylinder 6, and the reset spring 65 is compressed synchronously, and then the pushing of the connecting shaft 63 is stopped. The latch 66 continues to be against the surface of the connecting shaft 63 under the rebound action of the reset spring 65. At this time, pulling the connecting shaft 63 downward will cause the sleeve 64 to remain stationary under the abutment of the latch 66, while the boss 62 and the plug 61 will synchronously descend with the connecting shaft 63. When the boss 62 contacts the sleeve 64, the connecting shaft 63 The descending stroke is blocked, at this time, the plug 66 is squeezed and contracted along the inclined surface of the sliding sleeve 64, and then reset along the inclined surface of the boss 62. In this process, the plug 61 releases the blockage on the top of the positioning cylinder 6, and the raw materials inside the mixing cylinder 1 enter the upper half of the positioning cylinder 6 under the shearing and stirring action of the mixing component. By setting the positioning cylinder 6 to a transparent material, it is convenient for personnel to observe the raw material samples located inside the positioning cylinder 6, so as to judge the mixing process of the raw materials in the mixing cylinder 1. If the mixing degree meets the standard, the control rod 23 is controlled to end the mixing operation and start the cleaning and discharging operation. If the mixing degree does not meet the standard, the connecting shaft 63 is pushed again. At this time, the plug 61 pushes the raw material sample in the positioning cylinder 6 into the interior of the mixing cylinder 1 again and re-blocks the top of the positioning cylinder 6. The plug 66 is pressed by the reset spring 65 again against the outer surface of the connecting shaft 63 located between the boss 62 and the sliding sleeve 64. At this time, the boss 62 and the plug 66 are re-engaged.

[0044] It should be noted that when performing the cleaning and discharging operation, the positioning cylinder 6 needs to be unscrewed to release the screw connection between it and the discharge port 14, so as to expose the discharge port 14 to complete the extrusion and discharge process of the mixed raw materials inside the mixing cylinder 1 by the cleaning plate 56.
