Description

Technical Field

[0001] This utility model relates to the field of ceramic firing technology, and in particular to an energy-saving pitless blank storage machine. Background Technology

[0002] In the production of ceramic products such as ceramic tiles, refractory bricks, or daily-use porcelain, buffer devices are required to buffer the ceramic blanks, ensuring that the processing speeds of preceding and following processes are coordinated. For example, there is a difference between the preparation time and the firing time in the kiln; during continuous production, some blanks need to be temporarily stored. Similarly, the production time for daily-use porcelain from clay to blank is 24 hours. After drying, the blanks enter the bisque-firing kiln. If the bisque-firing blanks meet the strength requirements, they are sent to the glazing line. However, since the glazing line only operates during the day for easy quality control (color, surface quality, etc.), while the bisque-firing kiln operates 24 hours a day, a buffer device must be installed to store the blanks that come out of the bisque-firing kiln at night.

[0003] In existing buffer devices, ceramic blanks are transported to the buffer rack via a conveyor roller table. Then, a lifting mechanism drives the buffer rack upwards to raise the ceramic blanks, facilitating the transfer of the next batch to the next buffer zone. However, during installation, a foundation pit needs to be dug in the ground to accommodate the ceramic blanks in the highest buffer zone, increasing installation steps and reducing efficiency. Furthermore, the lifting mechanism requires upward movement of the buffer rack and the accumulated ceramic blanks, increasing the load and power consumption of the lifting mechanism, leading to higher operating energy consumption and costs. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an energy-saving pitless blank storage machine that can realize the buffering function of ceramic blanks. Furthermore, it is easy to install, requires no pit digging, has low load and power consumption, and low energy consumption and cost.

[0005] This utility model embodiment provides an energy-saving pitless billet storage machine, which includes:

[0006] A cache component is fixedly arranged, the cache component includes a plurality of cache racks spaced apart along a first direction, each cache rack having a plurality of support surfaces spaced apart along a vertical direction, and all the support surfaces at the same height together define the support plane of the cache area;

[0007] The roller table assembly includes a first roller conveying mechanism and a second roller conveying mechanism arranged and conveying along a first direction. The first roller conveying mechanism is located on one side of the buffer assembly along the first direction and is connected to the second roller conveying mechanism. The second roller conveying mechanism and the buffer assembly are arranged opposite to each other in the vertical direction, and any roller of the second roller conveying mechanism is arranged to avoid all the buffer frames.

[0008] A lifting mechanism, the movable end of which is fixedly connected to the roller table assembly, is configured to drive the roller table assembly to move relative to the buffer assembly in the vertical direction when the ceramic blank moves onto the first roller conveying mechanism, the first direction being perpendicular to the vertical direction.

[0009] The energy-saving pitless blank storage machine according to the embodiments of this utility model has at least the following beneficial effects: When ceramic blanks need to be buffered, the ceramic blanks are transferred to the first roller conveyor mechanism. Then, since the second roller conveyor mechanism and the buffer assembly are arranged opposite each other in the vertical direction, and all rollers of the second roller conveyor mechanism are arranged to avoid all buffer frames, the buffer frames do not obstruct the vertical movement of the second roller conveyor mechanism. Then, the lifting mechanism can drive the roller table assembly to move the ceramic blanks to a certain height. Next, the roller table assembly is started, allowing the first roller conveyor mechanism to send the ceramic blanks to the second roller conveyor mechanism along the first direction. At this time, the ceramic blanks move into the buffer area and are supported by the second roller conveyor mechanism. Immediately afterwards, the lifting mechanism drives the roller table assembly to move downward. During this process, the ceramic blanks can be transferred from the second roller conveyor mechanism to the support plane of the buffer area, thereby realizing the buffering function of the ceramic blanks.

[0010] Throughout the entire buffering process, the buffer components are fixed in place. The number of ceramic blanks accumulated on the buffer components does not affect the load and power of the lifting mechanism. The lifting mechanism only needs to provide upward drive for the roller table assembly and the fixed number of ceramic blanks on it. This reduces the performance requirements and manufacturing costs of the lifting mechanism, while also helping to reduce operating energy consumption and save energy. Furthermore, there is no need to dig a foundation pit in the ground for the buffer components. The ceramic blanks can be placed in each buffer area of ​​the buffer components by using the roller table assembly for vertical movement and conveying of the ceramic blanks. This improves the installation efficiency of the energy-saving pitless blank storage machine.

[0011] In some embodiments of this utility model, each of the buffer racks includes a horizontal bar and a vertical bar. The horizontal bar extends along a second direction, and there are multiple horizontal bars arranged at intervals along the vertical direction. There are two vertical bars, which are located on opposite sides of the horizontal bar along the second direction. The vertical bars are fixedly connected to all the horizontal bars. The second direction is perpendicular to the first direction and the vertical direction.

[0012] In some embodiments of this utility model, the roller table assembly further includes a lifting frame, the movable end of the lifting mechanism is fixedly connected to the lifting frame, and the first roller conveying mechanism and the second roller conveying mechanism are both located above the lifting frame and fixedly connected to the lifting frame.

[0013] In some embodiments of this utility model, the first roller conveying mechanism is provided with a detector, which is configured to detect whether a ceramic blank is present on the first roller conveying mechanism.

[0014] In some embodiments of this utility model, the energy-saving pitless billet storage machine further includes a support assembly, which includes multiple columns arranged in a matrix along a first direction and a second direction. The lifting frame is slidably connected to all the columns in the upper and lower directions, and the second direction is perpendicular to the first direction and the upper and lower directions.

[0015] In some embodiments of this utility model, the lifting frame is provided with multiple guide wheel assemblies, each of which is rotatably connected to the corresponding column to make the lifting seat rise and fall smoothly.

[0016] In some embodiments of this utility model, the support assembly further includes a top frame, which is located above the columns and is fixedly connected to all the columns. The lifting mechanism is located on the top frame and is a chain lifting device, with one end of the chain of the chain lifting device fixedly connected to the lifting frame.

[0017] In some embodiments of this utility model, the lifting mechanism includes a transmission component and a driving component. The transmission component is symmetrically arranged on opposite sides of the lifting frame along a second direction. The transmission component includes a sprocket, a chain, and a counterweight. The sprocket is rotatably mounted on the top frame, and the central axis of the sprocket extends along a first direction. Multiple sprockets are provided and arranged at intervals along the first direction. The chain is arranged correspondingly to the sprocket. One end of the chain is fixedly connected to the counterweight, and the other end is fixedly connected to the lifting frame. The counterweight is slidably connected to the column. The driving component is mounted on the top frame, and the output end of the driving component is connected to the sprocket to drive the sprocket to rotate.

[0018] In some embodiments of this utility model, the driving component includes a rotary drive, a first transmission shaft, and a second transmission shaft. All the sprockets located on the same side of the lifting frame along the second direction are coaxially connected to the same second transmission shaft. The opposite ends of the first transmission shaft are respectively connected to the second transmission shafts located on opposite sides of the lifting frame. The output end of the rotary drive is connected to the first transmission shaft to drive the first transmission shaft to rotate.

[0019] In some embodiments of this utility model, the length of the conveying plane of the first roller conveying mechanism is one-Nth of the length of the support plane of the buffer area, where N is a positive integer.

Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, it should be understood that features specified as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The following is for reference. Figures 1 to 7 This invention describes an energy-saving pitless billet storage machine provided according to an embodiment of the present invention.

[0033] like Figures 1 to 7 As shown, the energy-saving pitless blank storage machine according to the embodiment of this utility model can be applied to the production line of ceramic fired products (such as ceramic tiles, refractory bricks or daily-use porcelain with pads) to give full play to the good 600 buffer function of ceramic blanks, so that the speed of the front and rear processing processes can be coordinated and matched.

[0034] The energy-saving pitless billet storage machine has a first direction, a second direction, and a vertical direction. The first direction is perpendicular to both the second direction and the vertical direction, and the second direction is perpendicular to the vertical direction. In this embodiment, it is assumed that the first direction is the front-back direction and the second direction is the left-right direction.

[0035] The structure of the energy-saving pitless billet storage machine includes a buffer assembly 100 and a roller table assembly 200.

[0036] The buffer assembly 100 is fixedly installed, for example, by means of ground bolts. The buffer assembly 100 includes multiple buffer racks 110, which are arranged at certain intervals along a first direction. Each buffer rack 110 has multiple support surfaces, which are arranged at certain intervals along the vertical direction. All support surfaces at the same height together define the support plane of the buffer area.

[0037] Understandably, the supporting plane of each buffer zone is horizontal, providing sufficient support for the ceramic blank 600, allowing it to remain stably and safely within the buffer zone. The height of each buffer zone can be set according to actual needs, as long as it meets the requirements for the ceramic blank 600 to enter.

[0038] In this embodiment, each buffer rack 110 includes a horizontal bar 111 and a vertical bar 112. The horizontal bars 111 extend along a second direction, and multiple horizontal bars 111 are provided, arranged at certain intervals along the vertical direction. Two vertical bars 112 are provided, located on opposite sides of the horizontal bars 111 along the second direction, and the vertical bars 112 are fixedly connected to all the horizontal bars 111.

[0039] It is understood that the horizontal bars 111 and vertical bars 112 can be solid or hollow structures. The horizontal bars 111 and vertical bars 112 can be round or square. The gaps between any two adjacent horizontal bars 111 together form a buffer zone. Each buffer zone has openings on opposite sides along the first direction to allow the ceramic blank 600 to pass through. In this embodiment, one of the openings in the buffer zone serves as the inlet / outlet, allowing the ceramic blank 600 to enter and exit the buffer zone through this inlet / outlet. For all horizontal bars 111 on the same horizontal plane, the upper surfaces of all horizontal bars 111 together form a supporting plane for the buffer zone, and the height distance between any two adjacent horizontal bars 111 allows the ceramic blank 600 to pass through.

[0040] One or more ceramic blanks 600 can be placed in the same buffer area. When multiple ceramic blanks 600 are placed, they can be arranged in a matrix within the buffer area. The upper ends of all vertical rods 112 can be fixedly connected to the same fixed base, and the lower ends of all vertical rods 112 can be fixedly connected to another fixed base, thereby fixing the buffer assembly 100 to the ground with bolts.

[0041] The roller table assembly 200 includes a first roller conveying mechanism 220 and a second roller conveying mechanism 230. The first roller conveying mechanism 220 and the second roller conveying mechanism 230 are arranged along a first direction, and both can convey the ceramic blank 600 along the first direction. The first roller conveying mechanism 220 and the second roller conveying mechanism 230 can convey in both forward and reverse directions.

[0042] The first roller conveying mechanism 220 is disposed on one side of the buffer assembly 100 along the first direction, that is, the first roller conveying mechanism 220 is disposed near the inlet and outlet of the buffer area. The first roller conveying mechanism 220 is connected to the second roller conveying mechanism 230. The conveying plane of the first roller conveying mechanism 220 and the conveying plane of the second roller conveying mechanism 230 are at the same height position, and the ceramic blank 600 can be transferred between the first roller conveying mechanism 220 and the second roller conveying mechanism 230.

[0043] The length of the conveying plane of the first roller conveyor mechanism 220 is one-Nth of the length of the support plane of the buffer area, where N is a positive integer. It can be understood that the function of the first roller conveyor mechanism 220 is to convey ceramic blanks 600 to the buffer area and to receive ceramic blanks 600 exiting the buffer area. The support plane of the buffer area can hold M ceramic blanks 600 arranged along the first direction. If N is 1, the first roller conveyor mechanism 220 can simultaneously receive M ceramic blanks 600; if N is 2, the first roller conveyor mechanism 220 can simultaneously receive M / 2 ceramic blanks 600.

[0044] The second roller conveyor mechanism 230 and the buffer assembly 100 are arranged opposite each other in the vertical direction. Furthermore, any roller 251 of the second roller conveyor mechanism 230 is positioned to avoid all buffer frames 110; that is, the gap between any two adjacent buffer frames 110 in the first direction is large enough to allow at least one roller 251 of the second roller conveyor mechanism 230 to move. The length of the roller 251 of the second roller conveyor mechanism 230 is greater than the length of the crossbar 111, and the opposite ends of the roller 251 are located outside the buffer area to prevent the buffer frames 110 from obstructing the movement of the second roller conveyor mechanism 230.

[0045] Understandably, the function of the second roller conveyor 230 is to receive the ceramic blank 600 from the first roller conveyor 220, and to transfer the ceramic blank 600 to the corresponding buffer area by moving downwards, and to lift the ceramic blank 600 in the corresponding buffer area by moving upwards and to convey it to the first roller conveyor 220.

[0046] The lifting mechanism 300 has a movable end that can move in the vertical direction. The movable end of the lifting mechanism 300 is fixedly connected to the roller table assembly 200 to drive the roller table assembly 200 to move in the vertical direction, thereby adjusting the height position of the first roller conveying mechanism 220 and the second roller conveying mechanism 230. The lifting mechanism 300 is configured to drive the roller table assembly 200 to move relative to the buffer assembly 100 in the vertical direction when the ceramic blank 600 moves onto the first roller conveying mechanism 220.

[0047] It is understandable that the lifting mechanism 300 can be a chain lifting device, a screw lifting device, a wire rope lifting device, a hydraulic cylinder, etc., as long as it can meet the conditions for driving the roller table assembly 200 to lift. The lifting mechanism 300 can be installed on the ground or on the buffer assembly 100.

[0048] When the ceramic blank 600 is transferred from other conveyor lines to the first roller conveyor mechanism 220, it is located outside the buffer area. Then, the lifting mechanism 300 is activated, driving the first roller conveyor mechanism 220, the second roller conveyor mechanism 230, and the ceramic blank 600 upwards together. When the roller table assembly 200 rises to a certain height, the first roller conveyor mechanism 220 and the second roller conveyor mechanism 230 operate. The first roller conveyor mechanism 220 transports the ceramic blank 600 to the second roller conveyor mechanism 230, allowing it to enter the corresponding buffer area through the inlet and outlet.

[0049] Subsequently, the lifting mechanism 300 operates and drives the roller table assembly 200 to move downward, causing the conveying plane of the second roller conveying mechanism 230 to be lower than the corresponding buffer area. This causes the ceramic blank 600 to transfer from the conveying plane of the second roller conveying mechanism 230 to the supporting plane of the corresponding buffer area, allowing the ceramic blank 600 to remain stably in the buffer area. The roller table assembly 200 will then move directly back to its original position under the driving action of the lifting mechanism 300 to receive the next batch of ceramic blanks 600 from other conveying lines.

[0050] When it is necessary to remove the ceramic blank 600 from the buffer assembly 100, the lifting mechanism 300 drives the roller table assembly 200 to move upward to a certain height, so that the second roller conveying mechanism 230 can lift the ceramic blank 600 located in the corresponding buffer area, allowing the ceramic blank 600 to leave the support plane of the buffer area and be transferred to the second roller conveying mechanism 230; then, the second roller conveying mechanism 230 and the first roller conveying mechanism 220 work, the second roller conveying mechanism 230 conveys the ceramic blank 600 to the first roller conveying mechanism 220, so that the ceramic blank 600 leaves the buffer area; subsequently, the lifting mechanism 300 drives the roller table assembly 200 to move downward with the ceramic blank 600 to its original position, so that the first roller conveying mechanism 220 conveys the ceramic blank 600 to other conveying lines.

[0051] When performing buffering operations, the roller assembly 200 will start from the top buffer area to buffer the ceramic blank 600; when it is necessary to remove the ceramic blank 600 from the buffer area, the roller assembly 200 will start from the bottom buffer area to remove the ceramic blank 600.

[0052] In this embodiment, as Figures 1 to 7 As shown, the roller assembly 200 also includes a lifting frame 210. The movable end of the lifting mechanism 300 is fixedly connected to the lifting frame 210. The first roller conveying mechanism 220 and the second roller conveying mechanism 230 are both located above the lifting frame 210, and both the first roller conveying mechanism 220 and the second roller conveying mechanism 230 are fixedly connected to the lifting frame 210 by bolts.

[0053] It is understood that the lifting frame 210 can be formed by connecting multiple square tubes. The structure of the lifting frame 210 is not limited, as long as it can provide support for the first roller conveyor mechanism 220 and the second roller conveyor mechanism 230, and provide a connection position for the movable end of the lifting mechanism 300. The first roller conveyor mechanism 220 may include at least one roller conveyor 231 arranged sequentially along the first direction, and the second roller conveyor mechanism 230 may include at least one roller conveyor 231 arranged sequentially along the first direction.

[0054] like Figure 7 As shown, the first roller conveyor mechanism 220 and the second roller conveyor mechanism 230 have the same structure, both including a roller conveyor 231. The roller conveyor 231 includes a support, rollers 251, drive wheels 252, tension wheels 253, a drive chain, a drive wheel 254, and a drive motor 255. The support is fixedly connected to the lifting frame 210. The rollers 251 extend along a second direction, and their opposite ends are mounted on the support via bearing seats. There are multiple rollers 251, arranged evenly and at intervals along the first direction.

[0055] Each roller 251 has a drive wheel 252 at the same end. A drive motor 255 is mounted on a lifting frame 210. The output shaft of the drive motor 255 is connected to a reducer, and the output shaft of the reducer is coaxially connected to the drive wheel 254. A tension wheel 253 is rotatably mounted on a support, located below the roller 251 and above the drive wheel 254. At least one tension wheel 253 is provided on each opposite side of the drive wheel 254 along a first direction. A drive chain is wound around the drive wheel 254, the tension wheel 253, and all the drive wheels 252, and the drive chain is meshed with the drive wheel 254, the tension wheel 253, and all the drive wheels 252. When the drive motor 255 is running, the drive wheel 254 can drive the drive chain to operate, so that all the drive wheels 252 drive the roller 251 to rotate under the action of the drive chain, thereby realizing the conveying function of the roller conveyor 231 for the ceramic blank 600.

[0056] In some embodiments, such as Figure 4 As shown, the first roller conveying mechanism 220 is equipped with a detector 260, which is configured to detect whether a ceramic blank 600 exists on the first roller conveying mechanism 220.

[0057] Understandably, detector 260 can be a proximity switch or an infrared beam sensor. In some examples, detector 260 can emit a detection beam in a second direction to detect the presence of ceramic blank 600 on the first roller conveyor 220. In other examples, detector 260 can emit a detection beam in a vertical direction to detect the presence of ceramic blank 600 on the first roller conveyor 220.

[0058] In this embodiment, detector 260 is a proximity switch and is disposed on one side of the first roller conveying mechanism 220 along the second direction. When the ceramic blank 600 is transferred from other conveying lines to the position set by the first roller conveying mechanism 220, the ceramic blank 600 will trigger detector 260, causing detector 260 to generate a detection signal. When the ceramic blank 600 is transferred from the second roller conveying mechanism 230 to the position set by the first roller conveying mechanism 220, the ceramic blank 600 will trigger detector 260, causing detector 260 to generate a detection signal.

[0059] When detector 260 generates a detection signal and sends it to the controller electrically connected to it, the controller controls the lifting mechanism 300 to start, causing the lifting mechanism 300 to drive the roller table assembly 200 to move vertically. When it is necessary to buffer the ceramic blank 600, when it is detected that the ceramic blank 600 has been transferred from another conveyor line to the first roller conveyor mechanism 220, the lifting mechanism 300 will drive the roller table assembly 200 to move upward to a certain height, so as to transfer the ceramic blank 600 from the first roller conveyor mechanism 220 to the corresponding buffer area. When it is necessary to remove the ceramic blank 600, when it is detected that the ceramic blank 600 has been transferred from the buffer area to the first roller conveyor mechanism 220 via the second roller conveyor mechanism 230, the lifting mechanism 300 will drive the roller table assembly 200 to move downward to a certain height, so as to transfer the ceramic blank 600 from the first roller conveyor mechanism 220 to another conveyor line.

[0060] In some embodiments, such as Figures 1 to 7 As shown, the structure of the energy-saving pitless billet storage machine also includes a support assembly 400. The support assembly 400 includes multiple columns 410 arranged in a matrix along a first direction and a second direction. The lifting frame 210 is slidably connected vertically to all the columns 410. The columns 410 are mounted on the ground using expansion bolts.

[0061] Understandably, the lifting frame 210 can be mounted on the column 410 via guide wheels or a sliding rail slider pair, enabling the lifting frame 210 to move smoothly in the vertical direction. The structure of the column 410 is not limited; multiple reinforcing connecting rods can be provided between two adjacent columns 410 arranged along the first direction. The reinforcing connecting rods extend along the first direction, and the multiple reinforcing connecting rods are spaced apart in the vertical direction, which can enhance the structural strength of the column 410 and make the column 410 less prone to deformation.

[0062] In this embodiment, there are four columns 410. Figures 5 to 7As shown, the lifting frame 210 is equipped with multiple guide wheel assemblies 240, each guide wheel assembly 240 being rolledly connected to a corresponding column 410 to ensure smooth lifting and lowering of the lifting platform. Specifically, two guide wheel assemblies 240 are provided on opposite sides of the lifting frame 210 along the second direction, and the two guide wheel assemblies 240 are symmetrically arranged along the first direction. The guide wheel assemblies 240 are mounted on the lifting frame 210 and include a first guide wheel 241 and a second guide wheel 242. The central axis of the first guide wheel 241 extends along the second direction, and the central axis of the second guide wheel 242 extends along the first direction. Both the first guide wheel 241 and the second guide wheel 242 can rotate relative to the lifting frame 210 along their own central axes. The first guide wheel 241 and the second guide wheel 242 respectively roll in contact with two adjacent sides of the column 410. This arrangement prevents the lifting frame 210 from swaying along the first or second direction, thereby improving the movement stability of the lifting frame 210.

[0063] In some embodiments, such as Figures 1 to 4 As shown, the support assembly 400 also includes a top frame 420, which is located above the columns 410 and is fixedly connected to all the columns 410. A lifting mechanism 300 is mounted on the top frame 420, effectively utilizing the space above it. The lifting mechanism 300 is a chain lifting device, with one end of the chain 320 fixedly connected to the lifting frame 210. During operation, the chain 320 provides tension to the lifting frame 210, controlling the height of the lifting frame 210, the first roller conveyor mechanism 220, and the second roller conveyor mechanism 230.

[0064] In addition, a position detection switch can be set, which can be a proximity switch or an infrared beam sensor, and set on the corresponding column 410. The position detection switch can detect whether the roller table assembly 200 has moved down to the lowest position to receive the ceramic blank 600 from other conveyor lines or to transfer the ceramic blank 600 to other conveyor lines.

[0065] In this embodiment, as Figures 1 to 6 As shown, the lifting mechanism 300 is a chain lifting device, and the lifting mechanism 300 includes a transmission component and a drive component 310. The lifting frame 210 has transmission components on opposite sides along the second direction, and the transmission components are symmetrically arranged about the lifting frame 210.

[0066] The transmission components include a sprocket 313, a chain 320, and a counterweight 330. The sprocket 313 is rotatably mounted on the top frame 420, and its central axis extends along a first direction. Multiple sprockets 313 are arranged at certain intervals along the first direction. The chain 320 is correspondingly positioned to the sprockets 313; specifically, the chain 320 and sprockets 313 are corresponding in both number and position. One end of the chain 320 is fixedly connected to the counterweight 330, and the other end is fixedly connected to the lifting frame 210. The counterweight 330 is slidably connected to the column 410, allowing it to rise and fall smoothly. The drive component 310 is mounted on the top frame 420. The output end of the drive component 310 is connected to the sprocket 313 to drive the sprocket 313 to rotate, thereby causing the lifting frame 210, the first roller conveying mechanism 220 and the second roller conveying mechanism 230 to move in the vertical direction under the tension of the chain 320.

[0067] In this embodiment, in the same transmission component, there is one counterweight 330, located on the outer side of the lifting frame 210 along the second direction. Guide wheels 340 are provided at opposite ends of the counterweight 330 along the first direction. The central axis of the guide wheels 340 extends along the second direction, and the guide wheels 340 roll in contact with two adjacent columns 410. There are two sprockets 313, spaced apart along the first direction. There are two chains 320, each wound around one of the two sprockets 313. One end of each chain 320 is fixedly connected to the same counterweight 330, and the other end is fixedly connected to the lifting frame 210. Both the counterweight 330 and the lifting frame 210 are provided with rods 211 for connecting to the chains 320.

[0068] Specifically, the drive component 310 includes a rotary drive element, a first drive shaft, and a second drive shaft 312. Two second drive shafts 312 extend along a first direction and are located on opposite sides of the top frame 420 along a second direction. The first drive shaft extends along the second direction. Both the first and second drive shafts 312 are mounted on the top frame 420 via bearing mounts.

[0069] All sprockets 313 located on the same side of the lifting frame 210 along the second direction are coaxially connected to the same second drive shaft 312. Furthermore, the opposite ends of the first drive shaft are respectively connected to the second drive shaft 312 located on opposite sides of the lifting frame 210. Specifically, the first drive shaft is connected to the second drive shaft 312 via a reducer 311. The output end of the rotary drive component is connected to the first drive shaft to drive its rotation. Specifically, the rotary drive component may include a motor and a reducer, with the motor connected to the first drive shaft via the reducer.

[0070] When the motor is running, the first drive shaft rotates around its own central axis, and the second drive shaft 312 rotates around its own central axis under the power transmission of the first drive shaft, thereby driving the sprocket 313 to rotate, so that the chain 320 pulls the lifting frame 210, the first roller conveyor mechanism 220 and the second roller conveyor mechanism 230 to move in the up and down direction.

[0071] To facilitate maintenance of the drive unit 310, a support plate is provided on the top frame 420 to provide a standing position for maintenance personnel, and a ladder 520 is installed on the column 410 for maintenance personnel to access the top frame 420. Furthermore, railings 530 are installed on all four sides of the top frame 420 to improve safety and prevent maintenance personnel from accidentally falling from it. Additionally, safety nets 510 are installed on opposite sides of the lifting frame 210, and are fixedly connected to the column 410, located at the lower part of the column 410.

[0072] The energy-saving pitless blank storage machine provided in this embodiment of the utility model is used as follows: When it is necessary to perform buffering processing of ceramic blanks 600, the ceramic blanks 600 are transferred to the first roller conveying mechanism 220. Then, since the second roller conveying mechanism 230 and the buffer assembly 100 are arranged opposite each other in the vertical direction, and all the rollers 251 of the second roller conveying mechanism 230 are arranged to avoid all the buffer racks 110, the buffer racks 110 do not obstruct the vertical movement of the second roller conveying mechanism 230. Therefore, the lifting mechanism 300 can drive the roller table assembly 200. The ceramic blank 600 is moved upward to a certain height. Then, the roller table assembly 200 is activated, allowing the first roller conveying mechanism 220 to send the ceramic blank 600 along the first direction to the second roller conveying mechanism 230. At this time, the ceramic blank 600 moves into the buffer area and is supported by the second roller conveying mechanism 230. Immediately afterwards, the lifting mechanism 300 drives the roller table assembly 200 to move downward. During this process, the ceramic blank 600 can be transferred from the second roller conveying mechanism 230 to the support plane of the buffer area, thereby realizing the buffering function of the ceramic blank 600.

[0073] Throughout the entire buffering process, the buffer assembly 100 is fixed in place. The number of ceramic blanks 600 accumulated on the buffer assembly 100 does not affect the load and power of the lifting mechanism 300. The lifting mechanism 300 only needs to provide upward drive for the roller table assembly 200 and the fixed number of ceramic blanks 600 on it. This reduces the performance requirements and manufacturing cost of the lifting mechanism 300, and at the same time, it helps to reduce operating energy consumption and save energy. Furthermore, there is no need to dig a foundation pit in the ground for the buffer assembly 100. By using the roller table assembly 200 to move in the vertical direction and transport the ceramic blanks 600, the ceramic blanks 600 can be placed in each buffer area of ​​the buffer assembly 100. This improves the installation efficiency of the energy-saving pitless blank storage machine.
