Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, in particular to a hidden drive type dinner plate conveyor line. Background Art

[0002] At present, the main way of recycling tableware in large restaurants, especially those in schools, companies, factories, etc., is that diners first send the tableware to the recycling station, and then the staff will separate the leftovers and classify the tableware for recycling. At present, some places have begun to use flat belt conveyor lines for automatic plate recycling. Diners place the plates on the flat belt conveyor line, and the flat belt conveyor line transports the plates to the dishwasher inside the cafeteria.

[0003] For example, a Chinese patent with publication number CN204568613U discloses an automatic plate collection conveyor line, in which the driving mechanism in the prior art, namely the linear conveying unit, includes a first driven wheel, a linear module body, a tensioning directional wheel, a tensioning wheel, a leg frame assembly, a belt support, a linear polyurethane round belt, a motor-belt reducer assembly, a driving wheel assembly, a motor module frame, and a motor module body.

[0004] For example, a Chinese patent with publication number CN209796539U discloses a chain-type conveyor belt. In this prior art, the driving mechanism includes a driving motor and a roller chain; the driving motor is installed on a frame, and rotating shafts are respectively provided at both ends of the frame along the length direction, and each rotating shaft is provided with a sprocket, one of the rotating shafts is connected to the output shaft of the driving motor through a transmission belt, and the two ends of the roller chain are respectively provided on two sprockets.

[0005] Similar drive mechanisms can also be found in the Chinese patents with publication numbers CN215438267U and CN220925384U. In these prior arts, the drive mechanisms all include an exposed motor, and then the motor drives the drive wheel to rotate through an exposed chain drive or belt drive. However, since the tableware such as bowls and chopsticks are placed in the conveyed plate, it is inevitable that residual food and oil will be spilled when the plate and tableware are placed on the conveyor line. Chains, belts, gears, motors, etc. need to be cleaned in time after being contaminated with such oil, otherwise, in a high temperature and high humidity environment, the chains, belts, gears, and motors are easily corroded. When cleaning the plate conveyor line, it is relatively simple to use water to rinse, but based on the consideration of avoiding short circuits and leakage, the motor cannot be exposed to water. Although in the prior art, chains, belts, gears, motors, etc. are covered by installing a protective cover to play a waterproof role, protective covers with poor waterproof performance cannot meet the needs, and protective covers with higher waterproof performance will also increase costs. Some prior art technologies also install the motor at a location far away from the conveyor line. However, this arrangement will cause the conveyor line to occupy a larger space after the protective cover is installed. Utility Model Content

[0065] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0066] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of implementation. The change or adjustment of their relative relationship should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0067] In one embodiment, if Figure 1 , 5 As shown in Figures 6, the utility model provides a hidden drive type plate conveyor line, including a frame 101, on which a plate circulation groove 102 is provided. Considering the convenience of placing the plates, the plate circulation groove 102 is arranged at the upper end of the frame 101, and in one embodiment, the cross-sectional shape of the plate circulation groove 102 is an inverted trapezoid.

[0068] A closed box 104 is also provided on the frame 101, and a conveying assembly 106 passes through the plate circulation slot 102 and the closed box 104 to form a rotary conveyor line. The closed box 104 is closed at the upper end and the side end, which can prevent oil stains from splashing into the box, and its lower end can be closed or not. Generally, splashed oil stains will not enter the closed box 104 from the lower end. It should be noted that although the side end of the closed box 104 is closed, it is still provided with an opening for the conveying assembly 106 to enter the box, but the size of the opening can be slightly larger than the size of the conveying assembly 106, so as to avoid oil stains from splashing into the box due to the opening being too large.

[0069] Since the side ends of the closed box 104 are closed, the plates in the plate circulation slot 102 will not enter the closed box 104, so the closed box 104 will form a barrier to the plates, and therefore the closed box 104 is usually arranged at both ends of the conveyor line.

[0070] The frame 101 is provided with a supporting mechanism, which supports the conveying assembly 106, thereby avoiding direct contact and friction between the conveying assembly 106 and the frame 101. It is precisely because of the supporting mechanism that the conveying assembly 106 can be supported to form a rotary conveyor line.

[0071] A driving wheel 403, a rotating drum 404, a motor assembly, and a supporting mechanism are arranged in the closed box 104. Specifically, the rotating drum 404 is provided with an inner space, and the motor assembly is enclosed in the inner space of the rotating drum 404, and is used to drive the rotating drum 404 to rotate. The driving wheel 403 is sleeved on the rotating drum 404 and can rotate synchronously with the rotating drum 404. The conveying assembly 106 is arranged around the driving wheel 403. When the rotating drum 404 rotates, the driving wheel 403 drives the conveying assembly 106 to move, and the conveying assembly 106 operates in the form of a rotary conveying assembly. When a meal plate is placed on the conveying assembly 106 located in the meal plate circulation slot 102, the operating conveying assembly 106 will move the meal plate along the arrangement direction of the conveyor line.

[0072] Since the motor assembly is arranged inside the rotating drum 404, and the rotating drum 404 needs to rotate, the motor assembly needs to be supported. Specifically, the motor assembly is connected to the motor assembly through a supporting mechanism, and a part of the supporting mechanism is extended out of the space inside the drum. The part of the supporting mechanism extending out of the space inside the drum is fixedly connected to the frame 101 or the ground, thereby playing a supporting role for the motor assembly.

[0073] The utility model provides a rotating drum 404 with an inner space, and then provides a motor assembly in the inner space of the drum, and drives the rotating drum 404 to rotate through the hidden motor assembly, thereby avoiding the appearance of exposed chains, belts, gears, and motors. In this way, there is no need to worry about oil pollution of the chains, belts, gears, and motors, and there is no need to provide additional protective covers to avoid occupying additional space. In addition, the conveying line of the utility model is easy to clean, has good waterproof performance, and the protection level can reach IP67, which can also save a lot of space and cost.

[0074] As for the supporting mechanism, as an implementation scheme, Figure 6 As shown, the support mechanism includes a lead-out end 402, one end of which is located in the space inside the cylinder and connected to the motor assembly, and one end thereof extending out of the space inside the cylinder and connected to a support frame 401, and the support frame 401 is connected to the frame body 101, thereby playing a supporting role for the motor assembly.

[0075] The support frame 401 may have a slot, the lead-out terminal 402 may be engaged with the support frame 401, and the support frame 401 may be connected to the frame body 101 by bolts. It should be noted that the lead-out terminal 402 and the support frame 401, and the support frame 401 and the frame body 101 are not limited to the above connection methods, and any technology in the prior art that can fix the two together can be used, which will not be described in detail here.

[0076] In order to avoid occupying a larger space, in one embodiment, the width of the closed box 104 is approximately equal to the width of the frame 101, and the thickness of the closed box 104 is approximately equal to the thickness of the frame 101, that is, the rotating drum 404 equipped with the motor assembly is completely hidden in the closed box 104, and the additional space occupied by the closed box 104 is not increased. The closed box 104 is consistent in size with the frame 101, so as to minimize the space occupied by the plate processing area.

[0077] A support leg 103 is installed on the frame 101, and the support leg 103 is used to lift the frame 101 so that the closed box 104 and the frame 101 are suspended. Since the size of the closed box 104 and the frame 101 is almost the same, the closed box 104 and the frame 101 can be lifted to a certain height by the support leg 103, the bottom of the closed box 104 is roughly flush with the bottom of the frame 101, and the lower end of the closed box 104 and the frame 101 is 80 to 120 cm above the ground, for example, 80 cm, or 96 cm, or 100 cm, or 110 cm, or 120 cm, etc. Since the structure of an external motor and chain is adopted in the prior art, the external motor is mostly installed below the frame and blocked by a protective cover to achieve a closed and waterproof effect. Although this type of protective cover in the prior art is also suspended, its height from the ground is relatively small, which is inconvenient for personnel to clean below it. In this embodiment, since there is no external motor and the lower ends of the closed box 104 and the frame 101 are at a relatively high height from the ground, when the closed box 104 and the frame 101 are suspended in the air, it is convenient for personnel to clean the lower part.

[0078] In order to avoid a large number of plates being piled up on the conveyor line, which causes the plates placed on the conveyor assembly to rub against the moving conveyor assembly, the conveyor assembly needs to stop running when there is a backlog of plates on the conveyor line. In one embodiment, a proximity switch 503 and a baffle 502 are provided at the junction of the closed box 104 and the plate circulation slot 102. The baffle 502 is hinged to the closed box 104, and the hinged installation method is relatively mature in the prior art and will not be described here. A reset member is provided between the baffle 502 and the closed box 104, and the reset member can be a spring.

[0079] The proximity switch 503 is electrically connected to the controller 501, and the controller 501 is also electrically connected to the motor assembly. When the conveying assembly 106 drives the meal tray to move in front of the baffle 502, the personnel should take the meal tray off. If the personnel do not take the meal tray off, the meal tray will push against the baffle 502 to touch the proximity switch 503. At this time, the controller 501 receives a signal, and the controller 501 controls the motor assembly to stop driving the rotating drum 404 to rotate. The signal transmission method between the proximity switch 503 and the controller 501, and the control method between the controller 501 and the motor assembly are relatively mature in the prior art and will not be repeated here.

[0080] In one embodiment, if Figure 1 , 5 As shown in FIG. 6 , the utility model further proposes a hidden drive type plate conveyor line, including a frame 101, on which a supporting mechanism is provided, and a conveying component 106 is supported by the supporting mechanism. The conveying component 106 can avoid direct contact with the frame 101 through the support of the supporting mechanism.

[0081] The rotating drum 404 is provided with an inner space, and the motor assembly is located in the inner space of the rotating drum 404, which is used to drive the rotating drum 404 to rotate. The driving wheel 403 is sleeved on the rotating drum 404, and a positioning protrusion 405 is provided on the driving wheel 403. The positioning protrusion 405 is used to position the driving wheel 403 in the circumferential direction, so that the driving wheel 403 can rotate synchronously with the rotating drum 404. The conveying assembly 106 is wound around the driving wheel 403. When the rotating drum 404 rotates, the driving wheel 403 drives the conveying assembly 106 to move. When a meal plate is placed on the conveying assembly 106, the running conveying assembly 106 will move the meal plate along the arrangement direction of the conveyor line.

[0082] Based on waterproof considerations, an end cap 406 can be installed at the mouth of the rotating drum 404, and the end cap 406 can seal the mouth of the drum to prevent water, oil, etc. from entering the inner space of the drum, and its protection level can reach IP67. This sealing connection method is relatively mature in the prior art and will not be described in detail here. It only needs to ensure that the rotating drum 404 can rotate relative to the end cap 406.

[0083] Since the motor assembly is arranged inside the drum 404, and the drum 404 needs to rotate, the motor assembly needs to be supported. The end cover 406 is connected to the motor assembly and to the supporting mechanism. The supporting mechanism is used to support the motor assembly. This part of the supporting mechanism can be fixedly connected to the frame 101 or the ground, so as to play a supporting role for the motor assembly.

[0084] The utility model provides a rotating drum 404 with an inner space, and then provides a motor assembly in the inner space of the drum, and drives the rotating drum 404 to rotate through the hidden motor assembly, thereby avoiding the appearance of exposed chains, belts, gears, and motors. In this way, there is no need to worry about oil pollution of the chains, belts, gears, and motors, and there is no need to provide additional protective covers to avoid occupying additional space. In addition, the conveying line of the utility model is easy to clean, has good waterproof performance, and can also save more space and cost.

[0085] In one embodiment, if Figure 3 , Figure 5 As shown, the bottom of the dish circulation groove 102 near one end of the closed box 104 is provided with a first drain hole 301, and a collecting groove 302 corresponding to the first drain hole 301 is provided below the frame 101, and a drain pipe 305 is installed in the collecting groove 302. Since the dish circulation groove 102 is in an inverted trapezoidal shape, the water used to wash the dish circulation groove 102 and the liquid splashed from the dish need to be discharged from the dish circulation groove 102, so the first drain hole 301 is provided, and this part of water or liquid can leak from the first drain hole 301 into the collecting groove 302, and then be discharged from the drain pipe 305.

[0086] An inclined groove 304 extending along the moving direction of the conveying assembly 106 is provided at the upper end of the collecting tank 302, and the vertical downward projections of the driving wheel 403 and the rotating drum 404 fall on the inclined groove 304. In this way, although some water or liquid remaining on the conveying assembly 106 deviates from the first drain hole 301 as the conveying assembly 106 moves, it can still leak into the inclined groove 304 and then enter the collecting tank 302.

[0087] A pull-out trough 303 is installed on the collecting trough 302, and a second drain hole 306 is provided at the bottom of the pull-out trough 303. The liquid downstairs passes through the second drain hole 306 and is discharged from the drain pipe 305, while the solid remaining in the pull-out trough 303 can be cleaned by pulling out the pull-out trough 303.

[0088] For the motor assembly, in one solution, the motor assembly includes a motor, the output shaft of the motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the rotating drum 404 in a transmission manner. For example, the motor and the reducer can be fixedly installed in a cylindrical shell, and the cylindrical shell is connected to the inner wall of the rotating drum 404 through a bearing. The output shaft of the reducer is equipped with a gear, and the inner wall of the rotating drum 404 is provided with a gear ring meshed with the gear. The end cap 406 is fixedly connected to the cylindrical shell and connected to the supporting mechanism. The end cap 406 seals the barrel of the rotating drum 404 at the same time, and the rotating drum 404 can rotate relative to the end cap 406, so that the rotating drum 404 can be driven to rotate by the motor assembly. The connection method between the above-mentioned mechanisms is relatively mature in the prior art and will not be repeated here.

[0089] By making the lead-out end 402 fixedly connected to the cylindrical housing, the motor assembly can be supported by the supporting mechanism. The cable of the motor can be led out of the rotating drum 404 through the lead-out end 402.

[0090] The conveying component 106 may be an O-shaped conveyor belt. When the conveying component 106 is an O-shaped conveyor belt, the driving wheel 403 is provided with an annular groove matching the diameter of the O-shaped conveyor belt.

[0091] For the supporting mechanism, in one embodiment, as Figure 2 As shown, the supporting mechanism includes a mounting shaft 203, on which a transition wheel 204 is mounted and rotatably connected to the mounting shaft 203 through a bearing, and the conveying assembly 106 is also wound around the transition wheel 204. Both ends of the frame 101 can be provided with a closed box 104, in which a driving wheel 403 is mounted at one end, and in which a transition wheel 204 can be mounted at the other end.

[0092] The mounting shaft 203 has sliding parts 202 at both ends, and the frame 101 is installed with a sliding rod 201, and the sliding part 202 can slide along the sliding rod 201. A locking member is also included, and the sliding part 202 can be prevented from sliding along the sliding rod 201 by the locking member. By making the mounting shaft 203 movable, the tightness of the conveying assembly 106 can be adjusted. After the mounting shaft 203 is adjusted to a suitable position, the mounting shaft 203 is fixed by the locking member.

[0093] The locking member may be a snap ring or the like, which is relatively mature in the prior art and will not be described in detail here.

[0094] The supporting mechanism further includes a stopper 105 disposed on the plate circulation slot 102, and the stopper 105 is provided with a slot for allowing the O-shaped conveyor belt to pass through. The stopper 105 can move the conveying assembly 106 along the conveying direction, and can also prevent the O-shaped conveyor belt from contacting the bottom of the plate circulation slot 102 when moving.

[0095] like Figure 4 As shown, the supporting mechanism also includes a supporting shaft 108 disposed below the frame 101 , on which a supporting wheel 109 rotatably connected to the supporting shaft 108 via a bearing is mounted, and the conveying assembly 106 below the frame 101 is wound around the supporting wheel 109 .

[0096] As for the conveying component 106, it can be a chain plate, such as Figure 7 , 8 As shown, the chain plate is provided with a chain link 107, and the chain link 107 is meshed with the gear teeth provided on the driving wheel 403. When the driving wheel 403 rotates, it drives the chain plate to move.

[0097] Side rollers 110 are provided on both sides of the chain link 107. In this case, the supporting mechanism includes a slide groove provided on the frame 101, and the slide groove is adapted to the side rollers 110. When the chain plate is driven to move, the side rollers 110 contact the groove wall of the slide groove, and the rolling side rollers 110 can reduce friction. At the same time, the slide groove also plays a limiting role to prevent the chain plate from lateral deviation.

[0098] A lifting wheel 111 is also installed on the rotating drum 404 and rotates coaxially with the rotating drum 404 . The chain plate can be supported by the lifting wheel 111 .

[0099] It should be noted that the conveying component 106 is not limited to the above-mentioned O-type conveyor belt and chain plate, and other conveying mechanisms in the prior art may also be applicable. For example, the conveying component 106 may also be a keel chain, a roller conveyor line, a belt conveyor line, a synchronous belt conveyor line, etc. in the prior art, as long as adaptive adjustments are made to the structure of the driving wheel 403 and the structure of the supporting mechanism and the structure of the frame 101. Since the conveying component 106, the structure of the supporting mechanism, and the driving wheel 403 structure in the above-mentioned prior art are relatively well described in the prior art, they will not be repeated here.

[0100] In one embodiment, the inner diameter of the drum 404 is not less than 50mm, such as 50mm, or 60mm, or 76mm, or 90mm, or 140mm, etc., so that enough installation space can be reserved for the motor assembly. The difference between the diameter of the circumscribed circle of the driving wheel 403 and the outer diameter of the drum 404 is 60 to 110mm, such as 60mm, or 65mm, or 70mm, or 82mm, or 106mm, or 110mm, etc. Since the driving wheel 403 needs to drive the conveying assembly 106 to move, the driving wheel 403 needs to have a certain strength. If the difference between the diameter of the circumscribed circle of the driving wheel 403 and the outer diameter of the drum 404 is too small, the strength of the driving wheel 403 is difficult to ensure, and when the conveying assembly 106 is driven to move, it may break.

[0101] Regarding the connection between the driving wheel 403 and the rotating drum 404, a positioning protrusion 405 is provided on the driving wheel 403 to position the driving wheel 403 circumferentially. Circumferential positioning means that the driving wheel 403 can rotate synchronously with the rotating drum 404, and will not rotate relative to the rotating drum 404 along the circumference of the rotating drum 404. In one solution, the positioning protrusion 405 is a key bar. Specifically, the driving wheel 403 is centrally provided with a socket for the rotating drum 404 to pass through, and the hole wall of the socket is provided with a key slot, and the key bar is inserted into the key slot. The key bar is fixedly connected to the outer wall of the rotating drum 404 by welding, so that the driving wheel 403 can rotate together with the rotating drum 404. The driving wheel 403 can also be detachably connected to the rotating drum 404 by other connection methods in the prior art, so that it can be disassembled for maintenance or replacement.

[0102] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
