Description

Technical Field

[0001] The present invention generally relates to the technical field of mixing equipment, and more specifically, to a cement mortar mixing equipment. Background Art

[0002] Cement mortar mixing equipment is used to vigorously mix standard sand, water and cement. It is widely used in cement plants, construction units, relevant professional colleges and universities, and cement laboratories of scientific research institutions.

[0003] Traditional cement mortar mixing equipment usually adopts a method in which the stirring device is fixed and the stirring pot is raised and lowered, and stirring and separation are performed by adjusting the position of the stirring pot. For example, the Chinese utility model patent with authorization announcement number CN210552142U adopts this method. The disadvantage of this method is that the stirring pot has a limited lifting range. When the stirring pot is lowered to the limit position, the stirring head still does not leave the stirring pot, resulting in the stirring pot having to be tilted before it can be taken out, which is inconvenient to operate.

[0004] To this end, the Chinese utility model patent with authorization announcement number CN214925702U designs a cement mortar mixer, including a base, on which is provided a stirring pot positioning structure, the stirring pot positioning structure is the fixed hole in the patent, and the stirring pot positioning structure is used to position the stirring pot. A stirring device is also provided on the base, and the stirring device includes a stirring head and a lifting and rotating mechanism for driving the stirring head to lift and rotate, wherein the stirring head is a combination of the stirring shaft and stirring blades in the patent, and the lifting and rotating mechanism is a combination of the cylinder, guide column, fixed plate, motor, and transmission box in the patent.

[0005] When in use, place the stirring pot in the fixed hole, drive the stirring head up to a position away from the stirring pot through the lifting and rotating mechanism, pour the weighed material into the stirring pot, and then drive the stirring head down into the stirring pot by the lifting and rotating mechanism, and then drive the stirring head to rotate and stir. After the stirring is completed, the stirring head rises again.

[0006] The cement mortar mixing equipment in the prior art can realize the lifting and rotation of the mixing head, but in actual use, the mixing head needs to be cleaned frequently. However, the current cement mortar mixing equipment can only realize the mixing of materials and usually requires manual cleaning. It cannot realize automated production and cannot match the fully automated cement mortar molding production line. Summary of the invention

[0007] In view of this, an object of the present invention is to provide a cement mortar mixing device to solve the technical problem in the prior art that the mixing head needs to be cleaned manually, resulting in the inability to achieve automated production.

[0008] To achieve the above object, the cement mortar mixing equipment provided by the present invention adopts the following technical solutions: A cement mortar mixing equipment, comprising:

[0009] A base;

[0010] A mixing pot positioning structure, arranged on the base, and the mixing pot positioning structure is used for positioning the mixing pot;

[0011] A mixing device, arranged on the base, and the mixing device includes a mixing head and a lifting and rotating mechanism for driving the mixing head to lift and rotate;

[0012] The cement mortar mixing equipment further includes:

[0013] A cleaning device, arranged on the base and on one side of the mixing pot positioning structure, and the cleaning device is used for cleaning the mixing head;

[0014] The mixing device is movably assembled on the base, and the mixing head has a mixing station and a cleaning station within the moving range of the mixing device. When the mixing head moves to the mixing station, the lifting and rotating mechanism drives the mixing head to extend into the mixing pot and drives the mixing head to rotate for mixing; when the mixing head moves to the cleaning station, the lifting and rotating mechanism drives the mixing head to extend into the cleaning device to clean the mixing head.

[0015] The beneficial effects are as follows: The mixing device is movably assembled on the base. After the mixing is completed, the mixing head can move with the mixing device to the cleaning station. Subsequently, the lifting and rotating mechanism drives the mixing head to descend and extend into the cleaning device for cleaning. After the cleaning is completed, it can also return to the mixing station. There is no need for manual cleaning, and the degree of automation is higher, which can be adapted to a fully automated cement mortar forming production line.

[0016] As a further improvement, the lifting and rotating mechanism includes a lifting module arranged on the base. The lifting module has a lifting output end that can move up and down. The lifting module has a side facing the mixing pot positioning structure and the cleaning device, and the lifting output end is located on this side of the lifting module; the lifting and rotating mechanism further includes a rotating module. The rotating module has a rotating output end connected to the mixing head to drive the mixing head to rotate. The rotating module is suspended and installed on the lifting output end. The rotating module only provides rotational motion for the mixing head, and the number of components is small and the quality is lighter. The rotating module is suspended and installed on the lifting output end, realizing single-point assembly and fixation, facilitating the separate processing and assembly of the rotating module, and being easy to realize modular production and assembly.

[0017] As a further improvement, the rotating module is detachably assembled on the lifting output end. The rotating module and the lifting output end are detachably assembled, which is convenient for subsequent disassembly, maintenance or replacement.

[0018] As a further improvement, the slewing module includes a mounting base and a servo motor fixedly assembled on the mounting base. The servo motor is used to drive the stirring head to slewing. The servo motor is arranged extending in the up-and-down direction, and the servo motor, the mounting base, and the stirring head are arranged in a "one"-shaped layout extending vertically. The servo motor can accurately control the orientation of the stirring head when it stops, facilitating scraping the material on the stirring head. Moreover, the servo motor, the mounting base, and the stirring head are arranged in a "one"-shaped layout, eliminating the intermediate reversing transmission mechanism compared with the way of reversing transmission through bevel gears, resulting in a lighter weight and a smaller load on the lifting module.

[0019] As a further improvement, the mounting base includes a ring sleeve, and the servo motor is fixedly assembled on the top of the ring sleeve; a planetary mechanism connected to the stirring head is fixedly assembled at the bottom of the ring sleeve, and the servo motor is connected to the planetary mechanism. Both the servo motor and the planetary mechanism are assembled on the mounting base, integrated into a module. In addition, the servo motor and the planetary mechanism are arranged at the upper and lower ends respectively. Compared with the way that the mounting base, the servo motor, and the planetary mechanism are arranged in sequence from top to bottom, the overhang length is shorter, avoiding yaw due to excessive overhang.

[0020] As a further improvement, a material distribution mechanism for storing materials is fixedly provided on the mounting base, and an annular housing is fixedly assembled outside the planetary mechanism. A hose interface for connecting to the material distribution mechanism through a hose is provided on the annular housing. The annular housing is assembled on the mounting base, with a higher degree of integration.

[0021] As a further improvement, the lifting module includes a frame movably assembled on the base, and the frame is a frame structure formed by splicing plates. The frame structure can meet the strength requirements and has a lighter weight.

[0022] As a further improvement, the stirring pot positioning structure and the cleaning device are arranged in a straight line direction, and the stirring device is assembled on the base to reciprocate along this straight line direction. The stirring device reciprocates along a straight line direction, with a simpler structure.

[0023] As a further improvement, the stirring device is assembled on the base to reciprocate. Two limiting devices are provided on the base. When the stirring head moves to the stirring station, the stirring device is in blocking cooperation with one of the limiting devices for limiting; when the stirring head moves to the cleaning station, the stirring device is in blocking cooperation with the other limiting device for limiting.

[0024] As a further improvement, the cleaning device is an ultrasonic cleaning device. Description of the Drawings

Detailed implementation manners

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0038] The cement mortar mixing equipment provided by the present invention includes a mixing pot positioning structure, a mixing device, and a cleaning device. Among them, the mixing pot positioning structure and the cleaning device are arranged in sequence. The mixing device includes a mixing head and a lifting and slewing mechanism. The lifting and slewing mechanism can drive the mixing head to lift and slew. The mixing device can move in the arrangement direction of the mixing pot positioning structure and the cleaning device. When moving to the mixing pot positioning structure, it can mix the mixing pot, and when moving to the cleaning device, it can extend the mixing head into the cleaning device for cleaning, thus realizing fully automated production without manual intervention in cleaning and having higher efficiency.

[0039] After introducing the basic principles of the present invention, the various non-restrictive implementation manners of the present invention will be specifically introduced below. The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction without any limiting meaning.

[0040] Below, with reference to several representative implementation manners of the present invention, the principles and spirit of the present invention will be elaborated in detail.

[0041] Embodiment 1 of the cement mortar mixing equipment provided by the present invention:

[0042] As Figures 1 to 10 shown, the cement mortar mixing equipment includes a base 100, a mixing pot positioning structure 200, a mixing device 400, a cleaning device, and a translation module 600.

[0043] The base 100 is the installation foundation for other components. Here, the base 100 is an installation platform.

[0044] The function of the mixing pot positioning structure 200 is to fix the mixing pot 300 on the base 100 to prevent displacement during the mixing process and facilitate the loading and unloading work of the robot. The mixing pot positioning structure 200 can be the positioning holes of the prior art cited in the background art; or, the mixing pot positioning structure 200 includes two clamping jaws arranged on the base. The two clamping jaws are arranged oppositely. When the mixing pot is placed on the base, the two clamping jaws approach each other to clamp and fix the mixing pot.

[0045] As Figure 1 and Figure 2 shown, the cleaning device is an ultrasonic cleaning machine 500. The ultrasonic cleaning machine 500 can perform ultrasonic cleaning on the inserted mixing head 401. Here, the ultrasonic cleaning machine 500 is an ultrasonic cleaning device, which can directly purchase off-the-shelf products on the market or purchase accessories for self-assembly.

[0046] The ultrasonic cleaning machine 500 is provided with a water inlet and a water outlet to facilitate the automatic control of the water inlet and outlet. The ultrasonic cleaning machine 500 is provided with a liquid level sensor to realize the automatic control of the water level. A air knife mechanism is arranged above the ultrasonic wave to dry the mixing head 401 after the cleaning water is emptied.

[0047] In this embodiment, for the convenience of description, the interval direction between the ultrasonic cleaning machine 500 and the mixing pot positioning structure 200 is defined as the left-right direction.

[0048] The mixing device 400 includes a mixing head 401 and a lifting and rotating mechanism for driving the mixing head 401 to lift and rotate. Here, the lifting and rotating mechanism includes a lifting module 402 and a rotating module 403. The function of the lifting module 402 is to drive the rotating module 403 and the mixing head 401 to move up and down. When the mixing head 401 corresponds to the mixing pot 300, it can drive the mixing head 401 to extend into the mixing pot 300 for mixing operations. Define the position where the mixing head 401 is located at this time as the mixing station; when the mixing head 401 corresponds to the ultrasonic cleaning machine 500, it can drive the mixing head 401 to extend into the ultrasonic cleaning machine 500 for cleaning operations. Define the position where the mixing head 401 is located at this time as the cleaning station.

[0049] The specific structure of the lifting module 402 is asFigure 4 and Figure 5 As shown in Figure 2 and Figure 4 , the lifting module 402 includes a frame 404, which is installed on the base 100. The frame 404 bears the entire lifting module 402. It can be seen from Figure 2 and Figure 4 that the frame 404 is assembled by a bottom plate at the bottom, vertical plates extending vertically, and two side plates, jointly forming a frame structure. Of course, in order to improve the strength, reinforcing ribs are also arranged between the bottom plate and the side plates. In order to reduce the weight, weight-reducing holes can be opened on the premise of ensuring the strength. A first linear guide rail 405 extending up and down is fixed on the outer side of the vertical plate. There are two first linear guide rails 405, and the two first linear guide rails 405 are arranged at intervals left and right. A slider 406 is slidably assembled on each first linear guide rail 405. A slide plate 407 is fixed on the sliders 406 of the two first linear guide rails 405. The slide plate 407 is made of SUS304 material, which can ensure its strength and performance.

[0050] To drive the slide plate 407 to lift, a nut block 408 is connected to the inner side of the slide plate 407. A ball screw 409 is inserted through the nut block 408. When the ball screw 409 rotates, it can drive the nut block 408 to lift and move. A first servo motor 410 is also fixed on the frame 404. The first servo motor 410 is connected to the ball screw 409 to drive the ball screw 409 to rotate forward and backward. The first servo motor 410 has the advantage of precise control. Of course, in actual use, a cylinder or other structure can also be used to drive the slide plate 407 to lift.

[0051] To prevent external substances such as cement mortar from entering the first linear guide rail 405 and the ball screw 409 and affecting their normal operation, a surrounding frame is installed on the outer side of the vertical plate. The surrounding frame surrounds the first linear guide rail 405 and the ball screw 409. First bellows covers 411 are fixed on the top and bottom of the surrounding frame. One end of the first bellows cover 411 is connected to the slide plate 407, and the other end is fixed on the surrounding frame, which can cover the outside of the first linear guide rail 405 and the ball screw 409.

[0052] A first cable carrier 412 is also installed on the frame 404. One end of the first cable carrier 412 is installed on the frame 404, and the other end is installed on the slewing module 403 to ensure the fixation of the air pipes and cables during the lifting process of the slewing module 403.

[0053] The slewing module 403 is installed on the slide plate 407 of the lifting module 402, and the slide plate 407 drives the slewing module 403 to lift. The structure of the slewing module 403 is as shown in Figures 6 to 9 . Figures 6 to 9 ​​​​As shown, the slewing module 403 here is actually a planetary stirring module, whose function is to convert the rotational motion of the second servo motor 415 and the speed reducer 416 into the eccentric rotational motion of the stirring head 401 through the planetary mechanism 417, which can realize the directional and accurate control of the rotational orientation of the stirring head 401, facilitate automatic scraping of the stirring head 401, and at the same time, the feeding mechanism 700 can realize the timed and quantitative addition of raw materials.

[0054] The slewing module 403 includes a mounting base 413, and the mounting base 413 is mounted on the slide plate 407. Specifically, the mounting base 413 is detachably mounted on the slide plate 407 by bolts, thereby realizing the overall disassembly and replacement of the slewing module 403. One end of the mounting base 413 away from the slide plate 407 has a central through hole extending vertically to form a ring sleeve. An annular connecting seat 414 is fixedly installed at the top of the ring sleeve. Above the annular connecting seat 414, a speed reducer 416 and a second servo motor 415 are installed in sequence from bottom to top. Among them, both the second servo motor 415 and the speed reducer 416 are arranged with vertical extension. The stirring head 401, the second servo motor 415, the speed reducer 416, as well as the mounting base 413 and the annular connecting seat 414 are arranged in a vertically extending "one" shape as a whole. The second servo motor 415 no longer needs to drive the stirring head 401 to rotate through a commutation drive method, and the direct drive method can achieve lightweight and miniaturization, reducing the load of the lifting module 402.

[0055] At the bottom of the ring sleeve, a planetary mechanism 417 is fixedly assembled. The structure of the planetary mechanism 417 and its fixing method with the ring sleeve are as Figure 8 and Figure 9 shown. The planetary mechanism 417 includes a ring gear 421, a sun gear 423, and planetary gears 424. The ring gear 421 is assembled to the bottom of the ring sleeve by bolts 422. An input shaft 425 is connected to the sun gear 423, and the input shaft 425 is connected to the output shaft of the speed reducer 416, or the input shaft 425 is directly the output shaft of the speed reducer 416. A fixing seat 426 is fixed to the bottom of the sun gear 423 by bolts, and the fixing seat 426 is fixedly arranged relative to the sun gear 423. An output shaft 427 is connected to the planetary gear 424, and the output shaft 427 passes through the fixing seat 426. In order to support and position the output shaft 427, bearings are installed in the fixing seat 426 to support the output shaft 427. The stirring head 401 is fixedly connected to the output shaft 427. During use, the second servo motor 415 and the speed reducer 416 drive the sun gear 423 to rotate, and the sun gear 423 then drives the planetary gears 424 to revolve and rotate, thereby driving the stirring head 401 to slewing for stirring.

[0056] As Figure 6 and Figure 7As shown, a wire routing box 419 is also fixed on the speed reducer 416. The function of the wire routing box 419 is to guide air pipes, cables, etc. A material distribution mechanism 700 is also fixed on the mounting seat 413. The material distribution mechanism 700 is used to store materials and distribute them regularly and quantitatively. The material distribution mechanism 700 is a prior art and will not be elaborated here. As Figures 6 to 8 As shown, an annular housing 418 is fixed outside the gear ring 421. Specifically, the annular housing 418 is sleeved outside the gear ring 421, and the screw 428 passes through the annular housing 418 and is fixed on the gear ring 421. Of course, during actual fixation, threaded holes can be opened outside the gear ring 421 for the screw 428 to penetrate, and the screw 428 can also be used as a set screw. A plurality of screws 428 are arranged at intervals in the circumferential direction.

[0057] A hose interface 420 is opened on the annular housing 418. Specifically, the bottom of the annular housing 418 has an outward flange, and the hose interface 420 is fixed on the flange. During use, the hose interface 420 is connected to the material distribution mechanism 700 through a hose.

[0058] In this embodiment, the stirring head 401 is a stirring blade, which can increase the stirring area and improve the stirring effect. In other embodiments, the stirring head may include a shaft body extending vertically, and support rods are installed on the side of the shaft body to achieve stirring.

[0059] In this embodiment, the slewing module 403 is suspended and installed on the lifting module 402 through the mounting seat 413 to form a single-point support. The slewing module 403 and the lifting module 402 form separate modules and are then assembled, which is conducive to realizing modular design.

[0060] In order to drive the stirring device 400 to move left and right, so as to switch between the stirring station and the cleaning station, the stirring device 400 is installed on the base 100 through the translation module 600. The structure of the translation module 600 is as Figure 3 As shown, the translation module 600 includes second linear guide rails 601 extending in the left-right direction. There are two second linear guide rails 601 arranged at intervals in the front-back direction, and the two second linear guide rails 601 are parallel to each other. A sliding plate 602 is slidably assembled on the two second linear guide rails 601. The frame 404 of the lifting module 402 is fixedly installed on the sliding plate 602, and the sliding plate 602 drives the stirring device 400 to move left and right reciprocally. The sliding plate 602 is made of AL6061 material and is mainly used to carry and install the stirring device 400. The second linear guide rail 601 is used to bear the overturning moment of the stirring device 400 to ensure the stability of the equipment during stirring operation.

[0061] To drive the sliding plate 602 to move reciprocally, a cylinder 603 is installed on the base 100. The cylinder 603 is connected to the sliding plate 602, and the sliding plate 602 is driven to move reciprocally by the telescopic movement of the cylinder 603. AsFigure 3 As shown, a surrounding frame 604 is fixed on the base 100, and the surrounding frame 604 is formed by connecting multiple plates end to end. The second linear guide rail 601 and the cylinder 603 are both located inside the surrounding frame 604. As Figure 1 shown, when viewed in the horizontal direction, the stirring head 401 is located outside the surrounding frame 604. When the stirring device 400 switches between the stirring station and the cleaning station, even if there is material dripping from the stirring head 401, it will not flow to the second linear guide rail 601 and the cylinder 603, avoiding jamming due to contamination.

[0062] As Figure 3 shown, a second bellows cover 605 is installed on the surrounding frame 604. One end of the second bellows cover 605 is fixed on the surrounding frame 604, and the other end is fixed on the sliding plate 602. As the sliding plate 602 moves, the second bellows cover 605 can expand and contract, thus covering the outside of the second linear guide rail 601 and the cylinder 603, reducing the influence of water vapor and cement mortar on the equipment. A second drag chain 606 is also connected to the sliding plate 602. One end of the second drag chain 606 is connected to the base 100, and the other end is connected to the sliding plate 602, ensuring the fixation of the air pipes and cables during the translation of the equipment.

[0063] In order to accurately position the stirring device 400 at the stirring station and the cleaning station, as Figure 3 shown, two limiting devices 800 are fixed on the base 100, and the two limiting devices 800 are arranged at intervals in the left - right direction. When the stirring device 400 is in blocking cooperation with one of the limiting devices 800, the stirring device 400 is at the stirring station. When the stirring device 400 is in blocking cooperation with the other limiting device 800, the stirring device 400 is at the cleaning station. The stirring device 400 is in blocking cooperation with the limiting device 800 through the sliding plate 602 and the blocking block 607 on the sliding plate 602. The blocking block 607 is fixed on the sliding plate 602 and extends outside the surrounding frame 604.

[0064] The structure of the limiting device 800 is as Figure 10 shown. The limiting device 800 includes a mounting block 801 fixed on the base 100. The mounting block 801 is specifically an L - shaped structure. A limiting sleeve 802 is fixedly installed on the mounting block 801, and a hydraulic buffer 803 is fixedly installed on the mounting block 801. The hydraulic buffer 803 passes through the limiting sleeve 802, and the hydraulic buffer 803 ensures the stability of the equipment after it reaches the position. In other embodiments, the limiting device may only include the mounting block, and the limiting is achieved through the blocking cooperation between the mounting block and the stirring device.

[0065] During the installation of the present invention, the slewing module 403 and the lifting module 402 are first assembled separately, and then installed on the slide plate 407 of the lifting module 402 through the mounting seat 413, thus completing the assembly.

[0066] During use, place the mixing pot 300 on the mixing pot positioning structure 200 to fix the mixing pot 300. This part is usually completed by a robot. After mixing, the mixing head 401 moves to the cleaning station for cleaning and air drying. The mixing pot positioning structure 200 is loosened, and the mixing pot 300 moves to the next device for operation. The above process is repeated to achieve automatic mixing.

[0067] In this embodiment, the sliding plate 407 of the lifting module 402 constitutes the lifting output end of the lifting module 402, and the output shaft 427 of the planetary mechanism 417 in the slewing module 403 constitutes the slewing output end of the slewing module 403. In other embodiments, the planetary mechanism can be cancelled, and the mixing head is connected to the output shaft of the speed reducer, and the mixing head only realizes self-rotation.

[0068] During actual use, the materials of each component can be replaced and changed on the premise of meeting the usage requirements such as strength.

[0072] The main difference from Embodiment 1 is that in Embodiment 1, the mixing device is assembled on the base along a reciprocating movement, and two limiting devices are respectively arranged on the base corresponding to the mixing station and the cleaning station. In this embodiment, the moving path of the mixing device on the base is arc-shaped, and the two limiting devices can still be arranged at both ends. In other embodiments, the limiting devices can be cancelled, and the telescopic degree of the cylinder is controlled by relying on the accuracy to ensure reliable positioning.

[0073] Embodiment 4 of the cement mortar mixing equipment provided by the present invention:

[0074] The main difference from Embodiment 1 is that in Embodiment 1, the mixing pot positioning structure and the cleaning device are arranged along a straight line, and the mixing device is assembled on the base along a reciprocating movement in a straight line.
