[0002] In the production line of ceramic tiles, the drying process is indispensable. The drying process is generally carried out through rollers in the drying kiln, so that the products are transported to the drying kiln and forced to be dried by hot air. There are multiple layers of kiln-feeding rollers in the drying kiln.

[0003] In the existing multi-layer kiln feeding roller tables, in order to ensure drying efficiency and improve drying effects, the center distance between each layer of kiln feeding roller tables is getting smaller and smaller. If the traditional divided power multi-motor transmission mode is adopted, the installation space of the transmission device is limited, debugging is inconvenient, and the construction cost of the drying kiln is high. Utility Model Content

The electromagnetic clutch is configured so that when the electromagnetic clutch is energized, the electromagnetic clutch is connected to the corresponding transmission shaft in transmission. The driving sprocket is connected to the multiple clutch sprockets through a first chain.

[0010] The utility model has at least the following beneficial effects:

[0011] The roller conveying mechanism is used to convey the product. There are multiple roller conveying mechanisms, so that the multi-layer roller transmission device has multiple conveying routes, which improves the conveying efficiency of the product in the drying kiln and saves conveying time.

[0012] The roller conveying mechanism includes a transmission shaft and conveying rollers, and a plurality of conveying rollers are driven to rotate by a transmission shaft. The product is placed on the conveying rollers, and the product is conveyed by the rotating conveying rollers.

[0013] The power output mechanism is used to provide power for multiple roller conveying mechanisms. The power output mechanism includes a power component that provides a power source and a first transmission component for transmitting kinetic energy. The power component includes a motor, a driving shaft and a driving sprocket. The output shaft of the motor drives the driving shaft, driving the driving sprocket on the driving shaft to rotate. The driving sprocket transmits power to the clutch sprockets of multiple first transmission components through the first chain. The clutch sprocket drives the electromagnetic clutch to rotate. When the electromagnetic clutch is energized, the rotating electromagnetic clutch drives the transmission shaft to rotate, thereby realizing one motor driving multiple roller conveying mechanisms, reducing the number of motors laid, and reducing the laying cost and laying space of multi-layer roller transmission devices.

[0014] Each first transmission assembly is provided with an electromagnetic clutch, which can control whether the clutch sprocket is connected to the transmission shaft by controlling the electromagnetic clutch to be energized or de-energized, so as to control the starting number of the roller conveying mechanism. When debugging and overhauling each roller conveying mechanism, the clutch sprocket and the transmission shaft can be disconnected by the electromagnetic clutch, without disassembling the multi-layer roller transmission device, making debugging more convenient.

[0016] Through the above arrangement, when the electromagnetic clutch is energized, the electromagnetic clutch is connected to the driven shaft. When the motor is started, the first sprocket is driven to rotate around the axis of the driven shaft relative to the base, thereby realizing the rotation of the transmission shaft connected to the first sprocket relative to the base.

[0017] As a further improvement of the above technical solution, the power output mechanism also includes a second transmission assembly corresponding to the first transmission assembly one by one, the second transmission assembly includes a second sprocket and a second chain, the second sprocket is sleeved and connected to the transmission shaft, and the second chain is respectively connected to the first sprocket and the second sprocket.

[0019] As a further improvement of the above technical solution, a plurality of the roller conveying mechanisms are arranged at intervals in the up and down directions, and a transmission shaft extends horizontally and vertically connects a plurality of the conveying rollers.

[0020] Through the above arrangement, each roller conveying mechanism is used to convey different products to different heights of the drying kiln, thereby improving the conveying efficiency of the products and saving conveying time. The transmission shaft extends horizontally and is vertically connected to multiple conveying rollers, so that the transmission shaft can be transmitted to each corresponding conveying roller, and the transmission ratio of each conveying roller to the transmission shaft is the same, so that the roller conveying mechanism can smoothly convey the products.

[0022] Through the above arrangement, the bearing seat is connected and fixed to the machine base by connecting bolts passing through the adjustment holes and connected to the connecting holes of the machine base. The connecting bolts can move relative to the bearing seat in the adjustment holes, thereby realizing relative movement of the transmission shaft and the machine base in the horizontal direction, making the transmission connection between the transmission shaft and the multiple conveyor rollers more stable, and facilitating the assembly, debugging and maintenance of the multi-layer roller table transmission device.

[0023] As a further improvement of the above technical solution, a plurality of transition components are further provided on the machine base, and the plurality of transition components are respectively provided between two adjacent first transmission components. The transition component is also provided between the first transmission component and the power component, and the transition component is connected to the first chain.

[0024] Through the above arrangement, the transition component is arranged between two adjacent first transmission components so that the first chain runs smoothly between the two adjacent first transmission components; the transition component is arranged between the first transmission component and the power component so that the first chain runs smoothly between the first transmission component and the power component.

[0025] As a further improvement of the above technical solution, the transition assembly includes a transition shaft and a transition sprocket connected to each other, the transition shaft is rotatably mounted on the machine base, the transition shaft and the driven shaft are parallel to each other, and the first chain is meshingly connected with multiple transition sprockets.

[0026] Through the above-mentioned setting, the transition shaft and the driven shaft are set in parallel, so that the transition sprocket on the transition shaft and the clutch sprocket on the driven shaft both rotate in a straight line in the same direction, and the first chain is meshed with the transition sprocket. The transition sprocket is used to ensure that the first chain is always smoothly meshed with the clutch sprocket to avoid the clutch sprocket from being derailed.

[0027] As a further improvement of the above technical solution, in the projection of the arrangement direction of the plurality of roller conveying mechanisms, the center distance between the clutch sprocket and the transition sprocket is smaller than the sum of the radii of the two.

[0028] Through the above-mentioned arrangement, on the projection of the laying direction of the multiple roller conveying mechanisms, the center distance between the clutch sprocket and the transition sprocket is less than the sum of the radii of the two, that is, the clutch sprocket and the transition sprocket at least partially overlap, thereby avoiding the laying of the transition component resulting in an increase in the floor area and space of the machine base, and can increase the meshing area between the first chain and the clutch sprocket, thereby improving the transmission stability of the first chain and the clutch sprocket.

[0050] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0051] Reference Figures 1 to 4 , several embodiments of the multi-layer roller table transmission device of the utility model are given below.

[0052] like Figures 1 to 4 As shown, the multi-layer roller transmission device of the embodiment of the utility model includes a machine base 100, on which a power output mechanism 300 and a plurality of roller conveying mechanisms 200 connected by transmission are provided, so that the plurality of roller conveying mechanisms 200 can simultaneously convey products in and out of the drying kiln, thereby saving conveying time and improving drying efficiency.

[0053] It is understandable that each roller conveying mechanism 200 is provided with a transmission shaft 220 and a plurality of conveying rollers 210, and the plurality of conveying rollers 210 are laid at intervals in the horizontal direction to horizontally convey the products in and out of the drying kiln. Each conveying roller 210 extends horizontally, and the extension direction is perpendicular to the laying direction of the plurality of conveying rollers 210, and both ends of the conveying rollers 210 along the extension direction are rotatably mounted on the machine base 100. In each roller conveying mechanism 200, the transmission shaft 220 and the plurality of conveying rollers 210 are transmission-connected, so that the plurality of conveying rollers 210 can be rotated relative to the machine base 100 and the product can be conveyed only by rotating the transmission shaft 220.

[0054] In this embodiment, the power output mechanism 300 includes a power assembly 400 and a plurality of first transmission assemblies 500. Figure 1 shown.

[0055] It can be understood that the power assembly 400 includes a motor 410, a driving shaft 420 and a driving sprocket 421. The motor 410 is fixedly connected to the base 100. The output end of the motor 410 is transmission-connected to the driving shaft 420. Both ends of the driving shaft 420 are rotatably mounted on the base 100. The driving shaft 420 is penetrated and connected with the driving sprocket 421. The driving shaft 420 and the driving sprocket 421 are coaxially arranged. When the motor 410 is started, the driving sprocket 421 rotates about its own axis. Figure 3 shown.

[0056] It can be understood that the number of the first transmission components 500 is the same as the number of the roller conveyor mechanism 200. The first transmission component 500 includes a clutch sprocket 510 and an electromagnetic clutch 520, the clutch sprocket 510 is rotatably connected to the base 100, the clutch sprocket 510 is connected to the clutch end of the electromagnetic clutch 520, when the electromagnetic clutch 520 is powered, the electromagnetic clutch 520 is connected to the transmission shaft 220, the axis of the clutch sprocket 510 is parallel to the axis of the driving sprocket 421, and the driving sprocket 421 is connected to the plurality of clutch sprockets 510 through the first chain 550.

[0057] With such arrangement, when the motor 410 is started, the output end of the motor 410 drives the driving shaft 420 and the driving sprocket 421 to rotate, and the driving sprocket 421 drives the multiple clutch sprockets 510 to rotate through the first chain 550. When the electromagnetic clutch 520 is energized, the electromagnetic clutch 520 and the transmission shaft 220 are connected in transmission to drive the multiple transmission shafts 220 to rotate relative to the machine base 100, so that one motor 410 drives multiple roller conveying mechanisms 200, thereby reducing the number of motors 410 to be laid, and reducing the laying cost of multi-layer roller transmission devices.

[0058] Moreover, the power output mechanism 300 only needs to drive multiple transmission rollers to rotate, so that the corresponding roller conveying mechanism 200 can convey products. It has a simple structure, small space and easy debugging. The first transmission assembly 500 is provided with an electromagnetic clutch 520, which can control whether the electromagnetic clutch 520 is powered to control whether the motor 410 drives the corresponding roller conveying mechanism 200 to rotate, so as to start the corresponding roller conveying mechanism 200 according to the number of products to be dried, thereby saving power consumption. The electromagnetic clutch 520 can also facilitate the staff to debug and repair the power assembly 400 and each roller conveying mechanism 200 separately, without disassembling the entire multi-layer roller transmission device during the maintenance process.

[0059] In some embodiments, the electromagnetic clutch 520 can be directly mounted on the transmission shaft 220. When the electromagnetic clutch 520 is powered, the electromagnetic clutch 520 is connected to the transmission shaft 220 to drive the transmission shaft 220 to rotate, and the structure is simple. However, since the conveying roller 210 needs to be rotated by the transmission shaft 220, and the electromagnetic clutch 520 is also installed on the transmission shaft 220, the connection between the electromagnetic clutch 520 and the transmission shaft 220 will increase the length of the base 100 in the horizontal or vertical direction. If the transmission shaft 220 extends horizontally, the transmission shaft 220 horizontally connected to one end of the electromagnetic clutch 520 will increase the distance between the conveying roller 210 and the inlet or outlet of the drying kiln, affecting the transportation of the product; if the transmission shaft 220 extends vertically, the transmission shaft 220 connected to the electromagnetic clutch 520 will increase the height of the drying kiln, causing the heat in the drying kiln to be easily dissipated, thereby resulting in a large drying power required for the drying kiln and high energy consumption.

[0060] In this regard, the first transmission assembly 500 further includes a driven shaft 530 and a first sprocket 540. Figure 3 and Figure 4 Specifically, the driven shaft 530 is parallel to the driving shaft 420, and both ends thereof are rotatably connected to the base 100, the first sprocket 540 is sleeved on the driven shaft 530, and the two are coaxially connected, the clutch sprocket 510 is sleeved on the driven shaft 530, and is rotatably connected to the driven shaft 530, so that the clutch sprocket 510 can drive the electromagnetic clutch 520 to rotate around the axis of the driven shaft 530, the electromagnetic clutch 520 is sleeved on the driven shaft 530, when the electromagnetic clutch 520 is powered, the electromagnetic clutch 520 is connected to the driven shaft 530, and the first sprocket 540 is in transmission connection with the transmission shaft 220.

[0061] With such arrangement, the thickness of the first sprocket 540 is small, that is, the space required for the transmission between the first sprocket 540 and the transmission shaft 220 is small, and the connection position between the two can be set between two adjacent conveying rollers 210, so as to avoid the situation where the connection between the first transmission assembly 500 and the transmission shaft 220 extends the length or height of the transmission shaft 220 and the machine base 100, resulting in the conveying roller 210 being unable to receive the product in time or having difficulty in conveying the product from the conveying roller 210 to the drying kiln when the product enters and exits the drying kiln due to the large distance between the product and the conveying roller 210; or the temperature of the drying kiln is concentrated on the top, resulting in low drying efficiency and increased energy consumption.

[0062] It can be understood that when the motor 410 is started and the electromagnetic clutch 520 is energized, the motor 410 drives the clutch sprocket 510 to rotate through the driving sprocket 421 and the first chain 550, and the rotating clutch sprocket 510 drives the electromagnetic clutch 520, the driven shaft 530 and the first sprocket 540 connected in sequence to rotate, thereby realizing the rotation of the transmission shaft 220 through the transmission connection between the first sprocket 540 and the transmission shaft 220.

[0063] It can be understood that the power output mechanism 300 further includes a second transmission assembly 600, and the number of the second transmission assemblies 600 is the same as the number of the first transmission assemblies 500. Figure 1 As shown, the first sprocket 540 of each first transmission assembly 500 is connected to the transmission shaft 220 of each roller conveyor mechanism 200.

[0064] In this embodiment, the second transmission assembly 600 includes a second sprocket 610 and a second chain 620. The second sprocket 610 is sleeved and connected to the transmission shaft 220. The opposite ends of the second chain 620 are respectively connected to the first sprocket 540 and the second sprocket 610. When the motor 410 is started and the first sprocket 540 rotates, the second chain 620 realizes the transmission between the first sprocket 540 and the second sprocket 610, so that the second sprocket 610 drives the connected transmission shaft 220 to rotate. Figure 2 shown.

[0065] In some embodiments, each roller conveying mechanism 200 may be arranged at intervals in the horizontal direction, that is, in each roller conveying mechanism 200 , multiple conveying rollers 210 may be laid at intervals in the vertical direction, and the transmission shaft 220 may extend in the vertical direction and be connected to each conveying roller 210 .

[0066] It can be understood that each conveying roller 210 of the plurality of roller conveying mechanisms 200 located at the same height position forms a conveying layer for conveying products to achieve product conveying. When a roller conveying mechanism 200 fails or its corresponding first transmission assembly 500 or second transmission assembly 600 fails, the two roller conveying mechanisms 200 horizontally adjacent to the failed conveying roller 210 can still convey the product through their respective corresponding first transmission assemblies 500 and second transmission assemblies 600, without affecting the drying efficiency of the product.

[0067] In this embodiment, each roller conveying mechanism 200 is arranged at intervals in the vertical direction. Figure 1 As shown, in each roller conveying mechanism 200, a plurality of conveying rollers 210 are laid out at intervals in the horizontal direction, and a transmission shaft 220 extends in the horizontal direction and is respectively connected to the plurality of conveying rollers 210. Seven roller conveying mechanisms 200 are arranged on the machine base 100.

[0068] It can be understood that each roller conveyor mechanism 200 is a conveying layer for conveying products, that is, each roller conveyor mechanism 200 is responsible for conveying products at different heights in the drying kiln. Under this setting, the roller conveyor mechanism 200 can be assembled or repaired more conveniently, without having to make the conveying rollers 210 of the roller conveyor mechanism 200 correspond one-to-one with the conveying rollers 210 of other roller conveyor mechanisms 200, thus saving debugging steps and debugging time.

[0069] It can be understood that multiple roller conveying mechanisms 200 arranged horizontally or vertically utilize vertical space to increase the number of roller conveying mechanisms 200 laid out in the drying kiln, increase the number of products that can be conveyed at a time by the multi-layer roller transmission device, and thereby improve the drying efficiency of the products in the drying kiln.

[0070] Furthermore, the transmission shaft 220 is vertically connected to the corresponding plurality of conveying rollers 210 to ensure that the transmission shaft 220 has a transmission effect on each conveying roller 210 and the transmission ratios of the two are the same, so that the product can be conveyed smoothly.

[0071] In this embodiment, the multiple conveying rollers 210 in each roller table conveying mechanism 200 are arranged in the front-to-back direction, each conveying roller 210 extends in the left-to-right direction, and its left and right ends are rotatably connected to the base 100, the transmission shaft 220 extends in the front-to-back direction, and each transmission shaft 220 is transmission-connected to the right ends of the corresponding multiple conveying rollers 210.

[0072] It can be understood that the transmission shaft 220 can be a worm, and the right end of each conveying roller 210 can be connected to a worm wheel meshing with the worm; the transmission shaft 220 can also be a screw, and the right end of each conveying roller 210 can be connected to a gear corresponding to the screw, and the transmission of the transmission shaft 220 and multiple conveying rollers 210 is realized through the meshing action of the transmission shaft 220 and the worm wheel or gear.

[0073] It can be understood that the transmission shaft 220 is rotatably mounted on the machine base 100. That is, the transmission shaft 220 is rotatably connected to the bearing seat 230 through a bearing, and the bearing seat 230 is connected to the machine base 100.

[0074] Furthermore, the bearing seat 230 is provided with an adjustment hole 240, which extends in the horizontal direction and is perpendicular to the extension direction of the transmission shaft 220, that is, the adjustment hole 240 is an oblong hole extending in the left-right direction. The base 100 is provided with a matching connection hole 121 and a connection bolt 122, and the connection hole 121 is an internal threaded hole. The connection bolt 122 passes through the adjustment hole 240 and is threadedly connected to the connection hole 121 to achieve a rotational connection between the transmission shaft 220 and the base 100, and the connection bolt 122 can slide left and right in the adjustment hole 240. Since the conveying roller 210 is rotatably mounted on the base 100, the adjustment hole 240 can adjust the meshing position of the transmission shaft 220 and the conveying roller 210 in the left-right direction, which is convenient for assembly and debugging. Figure 2 shown.

[0075] It is understandable that the bearing seat 230 is externally connected to a dust cover, which is provided with an opening toward the conveying roller 210 so that one end of the conveying roller 210 can enter the dust cover through the opening and be connected to the transmission shaft 220 in the dust cover.

[0076] Since the plurality of roller conveying mechanisms 200 are arranged at intervals in the vertical direction, the plurality of first transmission assemblies 500 and the plurality of second transmission assemblies 600 are arranged at intervals in the vertical direction, that is, each driven shaft 530 corresponds to each other, and the driving shaft 420 corresponds to the driven shaft 530 to each other, so as to ensure that the clutch sprocket 510 on the driven shaft 530 corresponds to the driving sprocket 421 on the master and slave shafts. Since the driving sprocket 421 and the plurality of clutch sprockets 510 correspond to each other and are all connected to the first chain 550, the plurality of clutch sprockets 510 located in the middle are easily separated from the first chain 550.

[0077] In this regard, the base 100 is further provided with a transition assembly 700, and a plurality of transition assemblies 700 are provided, and are respectively provided between two adjacent first transmission assemblies 500, specifically between two adjacent driven shafts 530; the transition assembly 700 is also provided between the first transmission assembly 500 and the power assembly 400, specifically between the driving shaft 420 and its adjacent driven shaft 530, such as Figure 1 , Figure 3 and Figure 4 The transition assembly 700 is connected to the first chain 550 to ensure that the first chain 550 is firmly connected to the plurality of clutch sprockets 510 through the transition effect of the transition assembly 700, thereby preventing the clutch sprockets 510 and the first chain 550 from being decoupled.

[0078] In this embodiment, the transition assembly 700 includes a transition shaft 710 and a transition sprocket 720. Specifically, the transition sprocket 720 is sleeved and connected to the transition shaft 710, and the transition shaft 710 is rotatably mounted on the machine base 100. The transition shaft 710 is parallel to the driven shaft 530, that is, the axes of the two are parallel to each other, ensuring that the transition sprocket 720 and the clutch sprocket 510 can rotate relative to the machine base 100 in the same direction. The transition sprocket 720 corresponds to the clutch sprocket 510 and the driving sprocket 421 in the upper and lower directions, and the first chain 550 is meshed and connected with a plurality of transition sprockets 720, such as Figure 3 and Figure 4 shown.

[0079] It can be understood that the driving sprocket 421 and the plurality of clutch sprockets 510 are all rotatably engaged with the inner side of the first chain 550, the transition sprocket 720 is rotatably engaged with the outer side of the first chain 550, and the first chain 550 is meshedly connected with the transition sprocket 720 between two adjacent clutch sprockets 510 and between the adjacent clutch sprockets 510 and the driving sprocket 421. The transition sprocket 720 ensures that the first chain 550 is always firmly connected with the clutch sprocket 510.

[0080] Furthermore, in the projection of the laying direction of the plurality of roller conveyor mechanisms 200, the center distance between the clutch sprocket 510 and the transition sprocket 720 is less than the sum of their radii. With this arrangement, in the projection in the up-down direction, the clutch sprocket 510 and the transition sprocket 720 are offset left and right and have overlapping parts, ensuring stable transmission of the first chain 550.

[0081] It is understandable that the base 100 includes a first frame 110 and a second frame 120. Figure 1 As shown. The first frame 110 is provided with a conveying roller 210 for conveying products, and the conveying roller 210 is rotatably connected to the first frame 110; the second frame 120 is provided with a transmission shaft 220 and a power output mechanism 300. Specifically, the transmission shaft 220 is rotatably connected to the second frame 120 through a bearing seat 230, and the power assembly 400 and the first transmission assembly 500 are both arranged on the second frame 120, so that the power output mechanism 300 is laid separately from the conveying roller 210 for conveying products, which is convenient for maintenance personnel to debug and repair.

[0082] It is understood that the lower end of the first frame 110 is provided with a support foot 130 for adjusting the height of the conveying roller 210. Specifically, the support foot 130 is connected with an adjusting bolt 131, the adjusting bolt 131 extends upward, and the bottom surface of the first frame 110 is fixedly connected with an adjusting nut 132, and the adjusting bolt 131 is threadedly connected to the adjusting nut 132. Figure 1 When the upper and lower heights of the first frame 110 need to be sleeved, the support foot 130 can be directly rotated to change the relative positions of the adjusting bolt 131 and the adjusting nut 132, thereby achieving fine adjustment of the upper and lower positions of the conveying roller 210 on the first frame 110, so as to facilitate better transmission connection between the conveying roller 210 and the transmission shaft 220.
