Technical Field

[0001] The utility model relates to the technical field of tableware slag removal, in particular to a tableware slag removal spray device. Background Art

[0002] Before putting tableware into the tableware cleaning device, people will first put the tableware into the deslagging pool to soak so that most of the food residues on the tableware are separated from the tableware, and then take the soaked tableware out of the deslagging pool and put it into the tableware cleaning device for cleaning to avoid clogging the drain of the tableware cleaning device due to excessive food residues on the tableware. Although this soaking deslagging method can remove food residues with lower viscosity, it is difficult to remove food residues with higher viscosity. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a tableware residue removal spraying device. Compared with the traditional immersion residue removal, the use of the device can more effectively remove food residues with high viscosity on the tableware.

[0004] In order to solve the above-mentioned technical problems, the tableware residue removal spray device of the utility model is provided with a spray residue removal mechanism and a conveying mechanism. The conveying mechanism conveys the tableware with food residues to the spray residue removal mechanism, and the spray residue removal mechanism sprays cleaning liquid toward the tableware, thereby removing the food residues from the tableware; a residue conveying mechanism is provided below the spray residue removal mechanism to receive the food residues dropped from the tableware and convey it away.

[0005] Furthermore, a cleaning liquid supply pool is provided below the residue conveying mechanism, and the device is provided with an infusion pump to pump the cleaning liquid in the cleaning liquid supply pool to the spraying and removing residue mechanism; the residue conveying mechanism is provided with filter holes for the cleaning liquid sprayed onto the tableware by the spraying and removing residue mechanism to pass downward and fall back into the cleaning liquid supply pool.

[0006] Furthermore, the residue conveying mechanism is provided with a lateral extension portion extending to the side of the cleaning liquid supply tank, so as to pour the received food residue to the side of the cleaning liquid supply tank.

[0007] Furthermore, the residue conveying mechanism comprises a residue conveying belt, the filter holes are opened on the residue conveying belt, and the end of the residue conveying belt extends laterally to the side of the cleaning liquid supply tank to form the above-mentioned lateral extension part.

[0010] A cleaning liquid receiving member is provided below the lateral extension of the residue conveyor belt to receive the cleaning liquid falling from the downward belt surface of the residue conveyor belt; or

[0011] A residue receiving member and a cleaning liquid receiving member are provided below the lateral extension of the residue conveyor belt to respectively receive food residues and cleaning liquid dropped from the downward belt surface of the residue conveyor belt. The residue receiving member is closer to the end of the residue conveyor belt than the cleaning liquid receiving member.

[0012] Further:

[0013] The residue receiving member guides the received residue to the lower side of the end of the residue conveyor belt; or

[0030] The present invention is further described in detail below in conjunction with specific implementation methods.

[0031] Automatic tableware cleaning equipment Figure 1 , with a tableware inlet 101 at the rear and a tableware outlet 102 at the front. People put a set of tableware with food residues to be purified (not shown in the figure) into the automatic tableware purification device from the tableware inlet 101, and the automatic tableware purification device automatically removes the food residues on the tableware and automatically washes the tableware to purify the tableware, and the purified tableware is sent out from the tableware outlet 102.

[0032] Automatic tableware cleaning equipment Figure 2, including a conveying chain 11 in the front-to-back direction and a chain driving assembly 12 driving and connecting the conveying chain 11, a plurality of tableware carrying cages 10 arranged front and back along the conveying chain 11 are installed on the conveying chain 11, and the plurality of tableware carrying cages 10 are hung and installed on the chain links of the conveying chain 11. The conveying chain 11 is used as a conveyor belt, and forms a conveying mechanism with the chain driving assembly 12 to convey the plurality of tableware carrying cages 10. The chain driving assembly 12 is a prior art. A slag removal module 5, a cleaning module 6 and a drying module 7 are arranged in sequence from back to front between the tableware delivery port 101 and the tableware delivery port 102, and these three modules 5, 6, 7 constitute a tableware purification module. The conveyor chain 11 includes a lower working section 118 and an upper rotating section 119. The working section 118 is divided into the following five sections from the back to the front: a tableware receiving section 111 passing through the tableware delivery port 101, a slag removal section 112 passing through the slag removal module 5, a cleaning section 113 passing through the cleaning module 6, a drying section 114 passing through the drying module 7, and a tableware dumping section 115 passing through the tableware delivery port 102. The tableware automatic purification device includes a controller, which is electrically connected to the chain drive assembly 12, and controls the chain drive assembly 12 to drive the conveyor chain 11 to move so as to successively transport multiple tableware carrying cages 10 to various locations of the conveyor chain 11. The tableware carrying cage 10 is used as a tableware carrying container, and its cage mouth 100 faces upward in the upright state, and is used to carry tableware. The conveying chain 11 first delivers the tableware carrying cage 10 in an upright state to the tableware delivery port 101 to load the tableware; then the tableware carrying cage 10 is conveyed from the back to the front so that the tableware carrying cage 10 remains in an upright state and passes through the slag removal module 5, the cleaning module 6 and the drying module 7 in sequence. These three modules 5, 6 and 7 purify the tableware respectively. Specifically, the slag removal module 5 removes food residues from the tableware, the cleaning module 6 cleans the tableware, and the drying module 7 dries the cleaned tableware; the conveying chain 11 continues to convey the tableware carrying cage 10 and delivers the tableware carrying cage 10 to the tableware output port 102 to pour out the dried tableware; then the tableware carrying cage 10 that has poured out the tableware is conveyed to the tableware delivery port 101 through the rotating section 119 to load the tableware again, and this cycle is repeated. Since the tableware is loaded in the tableware carrying cage 10, the tableware carrying cage can restrict the tableware, ensuring that the tableware will not be scattered into the deslagging module 5, the cleaning module 6 and the drying module 7 during the process of deslagging, cleaning and drying.

[0033] See Figure 2, the controller controls the chain drive assembly 12 to drive the conveyor chain 11 to perform intermittent conveying as follows: the conveyor chain 11 conveys a tableware carrier cage 10 that is not loaded with tableware to the tableware delivery port 101 and then stops for 3.5 seconds, people put tableware into the tableware carrier cage 10 from the tableware delivery port 101 within 3.5 seconds, and then the conveyor chain 11 sends the tableware carrier cage 10 loaded with tableware forward within 3.5 seconds and sends the next tableware carrier cage 10 that is not loaded with tableware to the tableware delivery port 101, and so on, multiple tableware carrier cages 10 pass through the tableware delivery port 101 in this way and load multiple sets of tableware in succession. After loading the tableware, the multiple tableware carrier cages 10 pass through the slag removal module 5, the cleaning module 6 and the drying module 7 in succession.

[0034] See Figure 2 , a transverse support bar 131 is provided below the rotating section 119 of the conveying chain 11. Taking a tableware carrier cage 10 without tableware on the rotating section 119 of the conveying chain 11 as an example, the tableware carrier cage 10 is placed horizontally with the cage mouth 100 facing backwards, and its rear upper corner is used as a hanging corner 105, which is hung on the chain link of the conveying chain 11, and its front lower corner 106 and rear lower corner 107 are supported on the transverse support bar 131, and it moves backward under the conveying of the conveying chain 11. The rear end of the transverse support bar 131 is provided with a rear arc-shaped guide bar 1311 extending backward and downward, and the tableware automatic purification equipment is provided with a vertical feeding guide bar 132 behind the tableware receiving section 111 of the conveying chain 11. The tableware carrying cage 10 moves from the rear end of the rotating section 119 to the tableware receiving section 111. During this process: the front lower corner 106 of the tableware carrying cage 10 moves to the rear arc guide strip 1311 and moves downward along the rear arc guide strip 1311 under the action of gravity. Guided by the rear arc guide strip 1311, the tableware carrying cage 10 as a whole rotates counterclockwise downward with the hanging angle 105 as the rotation center, and the rear lower corner 107 of the tableware carrying cage 10 stands up backward to resist the feeding guide strip 132. In this state, the tableware carrying cage 10 switches from a horizontal state to a tableware receiving state with a low front and a high rear, and its cage mouth 100 is tilted toward the upper rear, and the tableware carrying cage 10 is in an upright state, which can be used for tableware loading.

[0035] See Figure 2 A cutlery guide plate 133 with a lower front and a higher back is provided at the cutlery delivery port 101. The cutlery receiving section 111 of the conveyor chain 11 transports the cutlery carrier cage 10 downwards. During this process, the cutlery carrier cage 10 always remains in a cutlery receiving state under the guidance of the feed guide bar 132. The cutlery receiving section 111 of the conveyor chain 11 transports the cutlery carrier cage 10 to the cutlery delivery port 101, so that the cage mouth 100 of the cutlery carrier cage 10 is aligned with the cutlery delivery port 101 and the cutlery loading guide plate 133, and the lower end of the cage mouth 10 is lower than the cutlery loading guide plate 133, and then the conveyor chain 11 stops conveying, allowing the cutlery carrier cage 10 to stay at the cutlery delivery port 101 for 3.5 seconds. Figure 2 People put tableware into the tableware inlet 101 within 3.5 seconds, and the tableware put into the tableware inlet 101 is guided by the tableware guide plate 133 to be loaded into the tableware carrying cage 10 from the cage opening 100. The tableware receiving section 111 of the conveying chain 11 sends the tableware carrying cage 10 loaded with tableware downward from the tableware inlet 101 after 3.5 seconds.

[0036] Slag removal module 5 Figure 2 , Figure 3 and Figure 4 , including a slag removal box 51 with an upward opening, a transverse partition 52 is provided inside the slag removal box 51, and the transverse partition 52 divides the interior of the slag removal box 51 into an upper part 511 and a lower part 512. The transverse partition 52 is provided with a slag discharge opening 521 that passes through from top to bottom to connect the upper part 511 of the slag removal box 51 to the lower part 512. A residue conveying mechanism 53 is provided at the lower part 512 of the slag removal box 51, and the residue conveying mechanism 53 is aligned with the slag discharge opening 521 of the transverse partition 52. The tableware receiving section 111 of the conveying chain 11 and the tableware carrying cage 10 that moves downward along the tableware receiving section 111 are both located above the slag removal box 51, and the tableware carrying cage 10 is located above the slag discharge opening 521. The bottom and side of the tableware carrying cage 10 are provided with slag discharge openings 109. When the tableware is loaded into the tableware carrier cage 10 in an inclined downward direction, some food residues on the tableware carrier cage 10 will fall forward and be discharged from the residue discharge port 109 of the tableware carrier cage 10 to the outside of the tableware carrier cage 10. Most of the food residues will fall from the residue discharge port 521 of the transverse partition 52 to the residue conveying mechanism 53, and will be received and sent away by the residue conveying mechanism 53, while a small part will fall onto the transverse partition 52. The residue removal section 112 of the conveying chain 11 includes a rear transverse residue removal section 1121 and a front vertical residue removal section 1122. The tableware carrier cage 10 moves from the lower end of the tableware receiving section 111 of the conveying chain 11 to the transverse slag removal section 1121. The transverse slag removal section 1121 transports the tableware carrier cage 10 forward and laterally so that the tableware carrier cage 10 gradually moves away from the feed guide bar 132. During this process, the tableware carrier cage 10 as a whole rotates counterclockwise downward to a natural drooping state with the hanging angle 105 as the rotation center under the action of gravity, and most of the food residues on the tableware are poured out. These food residues are discharged from the slag discharge port 109 of the tableware carrier cage 10 to the outside of the tableware carrier cage 10. Most of them fall from the slag drop port 521 of the transverse partition 52 to the residue conveying mechanism 53, and are received and sent away by the residue conveying mechanism 53. A small part will fall on the transverse partition 52. Figure 2Since the tableware carrying cage 10 is only hung on the conveying chain 11 at the hanging angle 105, the tableware carrying cage is not vertically upward in the natural drooping state but slightly tilted, but still in the upright state with the cage mouth 100 facing upward. The slag removal module 5 is provided with a vertical guide bar 134 at the vertical slag removal section 1122 of the conveying chain 11. The tableware carrying cage 10 moves from the horizontal slag removal section 1121 of the conveying chain 11 to the vertical slag removal section 1122. During this process, the tableware carrying cage 10 in the natural drooping state approaches and abuts against the vertical guide bar 134, and is guided by the vertical guide bar 134 to rotate backward counterclockwise to a nearly vertical state. In this state, the cage mouth 100 is still kept facing upward and is still in the upright state.

[0037] See Figure 4 , the lower part of the slag removal box 51 is connected to a clean water supply pipe 91, and a liquid inlet valve 911 is provided on the clean water supply pipe 91. A heater 92 and a bottom water level sensor 93 are provided at the bottom of the slag removal box 51. The heater 92 is lower than the sensing height of the bottom water level sensor 93. A cleaning liquid water level sensor 94 is provided at the lower part 512 of the slag removal box 51, and the cleaning liquid water level sensor 94 is higher than the bottom water level sensor 93. The controller is electrically connected to the liquid inlet valve 911, the bottom water level sensor 93, the heater 92 and the cleaning liquid water level sensor 94. The controller controls the liquid inlet valve 911 to open, so that the clean water supply pipe 91 inputs clean water to the lower part 512 of the slag removal box 51, and the lower part 512 of the slag removal box 51 is used as a clean water storage pool to store clean water. Since the clean water storage pool belongs to the slag removal module 5, the clean water storage pool is referred to as the slag removal pool 512 in this article. As the clean water is input into the slag removal pool 512, the water level of the slag removal pool 512 gradually rises. Since the heater 92 is lower than the sensing height of the bottom water level sensor 93, when the water level of the slag removal tank 512 rises to the sensing height of the bottom water level sensor 93, thereby causing the bottom water level sensor 93 to generate an electrical signal, the water level of the slag removal tank 512 is already higher than the heater 92, and the controller controls the heater 92 to start working to heat the clean water in the slag removal tank 512. When the clean water level rises to the sensing height of the cleaning liquid water level sensor 94, thereby causing the cleaning liquid water level sensor 94 to generate an electrical signal, the controller controls the liquid inlet valve 911 to close.

[0038] See Figure 3 , Figure 4 and Figure 6The slag removal module 5 is also a tableware slag removal spray device, which is provided with a spray slag removal mechanism 54 on the front upper part of the slag removal box 51. The spray slag removal mechanism 54 includes front and rear water baffles 541 and 542. Front and rear slag removal spray pipes 543 and 544 are provided between the front and rear water baffles 541. The front slag removal spray pipe 543 includes 9 spray openings 546 arranged vertically and a horizontal slag removal spray pipe 545 facing backward. The rear slag removal spray pipe 544 includes 3 spray openings 546 arranged vertically (not shown in the figure due to the viewing angle) and a horizontal slag removal spray pipe 545 facing forward. The spray openings 546 of each adjacent two horizontal slag removal spray pipes 545 are staggered horizontally, such as Figure 7 The slag removal module 5 is provided with a slag removal liquid infusion pump 55, the inlet end of the slag removal liquid infusion pump 55 is connected to the slag removal pool 512, and the outlet end is connected to 12 horizontal slag removal spray pipes 545. The slag removal pool 512 serves as a cleaning liquid supply pool. The slag removal liquid infusion pump 55 pumps the clean water in the slag removal pool 512 into the horizontal slag removal spray pipes 545 to provide clean water for the horizontal slag removal spray pipes 545. The vertical slag removal section 1122 of the conveying chain 11 passes between the front and rear rows of horizontal slag removal spray pipes 543 and 544. The tableware carrier cage 10 is kept in an upright position and moves upward along the vertical slag removal section 1122, passing between the front and rear rows of horizontal slag removal spray pipes 543, 544. During this process, the slag discharge port 109 opened at the front and rear sides of the tableware carrier cage 10 also serves as a cleaning liquid spray port 1091. The front and rear rows of horizontal slag removal spray pipes 543, 544 spray clean water from the cleaning liquid spray port 1091 into the tableware carrier cage 10 sideways, spraying it onto the tableware loaded on the tableware carrier cage 10. Using clean water as a cleaning liquid, most of the remaining food residues are sprayed off the tableware, thereby removing the food residues on the tableware and purifying the tableware. The front and rear water retaining plates 541, 542 can block the water splashed on them to prevent the water from being sprayed to other places. The slag removal module 5 removes food residues on the tableware by spraying, and uses the impact force of the cleaning liquid sprayed on the tableware to wash away the food residues on the tableware. Compared with soaking, spraying can more effectively remove food residues with higher viscosity on the tableware. The vertical slag removal section 1122 and the tableware carrier cage 10 moving upward along the vertical slag removal section 1122 are located above the front of the slag removal box 51 and also located above the front of the residue conveying mechanism 53. The water sprayed on the tableware is discharged from the slag discharge port 109 of the tableware carrier cage 10 to the outside of the tableware carrier cage 10 together with the food residue, first falling onto the transverse partition 52 and then flowing along the transverse partition 52 to the slag discharge port 521, and by the way, the food residue that has previously fallen onto the transverse partition 52 is washed away. The water and the food residues fall from the residue discharge port 521 onto the residue conveying mechanism 53. The residue conveying mechanism 53 receives the water and the food residues, filters out the food residues and then sends them away. The water passes through the residue conveying mechanism 53 and falls back to the residue removal pool 512 (see FIG. Figure 4 ) for reuse.

[0039] See Figure 3 , Figure 4 and Figure 5 The residue conveying mechanism 53 includes a residue conveying belt 531 and a conveying belt driving mechanism 532 that drives and connects the residue conveying belt 531. The conveying belt driving mechanism 532 is a prior art. The left end 5311 of the residue conveying belt 531 is the terminal end, and a lateral extension portion 533 is provided that extends laterally to the side of the residue removal pool 512. The residue conveying belt 531 is provided with a filter hole 5312. When water and food residues fall onto the residue conveying belt 531 together, water and some food residues that are smaller than the filter hole 5312 pass through the filter hole 5312 downward and fall into the residue removal pool 512. Food residues that are larger than the filter hole 5312 cannot pass through the filter hole 5312 downward and remain on the residue conveying belt 531. The conveying belt driving mechanism 532 drives the residue conveying belt 531 to transport the food residues to the left end 5311 of the residue conveying belt 531, and pours the food residues to the side of the residue removal pool 512. See Figure 8 A residue receiving member 534 and a cleaning liquid receiving member 535 are provided below the lateral extension 533 of the residue conveyor belt 531. The residue receiving member 534 is closer to the left end 5311 of the residue conveyor belt 531 than the cleaning liquid receiving member 535. The left end of the residue receiving member 534 is lower than the right end and is provided with a slag outlet 5341. The residue receiving member 534 receives food residues that fall from the downward belt surface of the residue conveyor belt 531. The food residues are guided by the residue receiving member 534 to flow to the left end of the residue receiving member 534 and then fall from the slag outlet 5341 at the left end of the residue receiving member 534 to the bottom of the left end 5311 of the residue conveyor belt 531. The cleaning liquid receiving member 535 is connected to the slag removal tank 512, receives the cleaning liquid that falls from the downward belt surface of the residue conveyor belt 531 and discharges the received cleaning liquid to the slag removal tank 512.

[0040] See Figure 2 The cleaning module 6 is also a tableware spraying and immersing device, including a primary spraying and immersing unit 610 and a secondary spraying and immersing unit 620. The cleaning section 113 of the conveying chain 11 is divided into a primary cleaning section 1131 and a secondary cleaning section 1132. The primary cleaning section 1131 passes through the primary spraying and immersing unit 610, and the secondary cleaning section 1132 passes through the secondary spraying and immersing unit 620. The tableware carrying cage 10 first moves forward from the slag removal section 112 of the conveying chain 11 to the primary cleaning section 1131, that is, from the slag removal module 5 to the cleaning module 6, and receives spraying and immersion from the primary spraying and immersing unit 610, and then moves forward from the primary cleaning section 1131 to the secondary cleaning section 1132, and receives spraying and immersion from the secondary spraying and immersing unit 620.

[0041] Primary spray leaching unit 610 Fig. 9, including a leaching pool 61, in which a cleaning liquid is stored. The cleaning liquid is a mixture of clean water and negative ion water containing hydroxide ions. In this embodiment, a negative ion water generator 95 provided by Kunshan Nano Green Energy Environmental Protection Technology Co., Ltd. is used to provide negative ion water for the leaching pool 61. A spray pipe 625 with a spray port 629 facing backward is provided above the leaching pool 61. The primary spray leaching unit 610 is also provided with a cleaning infusion pump 63. The liquid inlet end of the cleaning infusion pump 63 is connected to the leaching pool 61, and the liquid outlet end is connected to the spray pipe 625. The cleaning liquid in the leaching pool 61 is pumped to the spray pipes 625 and 626. The primary cleaning section 1131 of the conveying chain 11 is "U"-shaped, and its bottom extends into the leaching pool 61. The tableware carrying cage 10 moves from the slag removal section 112 of the conveying chain 11 to the primary cleaning section 1131, and the tableware after slag removal is sent to the primary spray leaching unit 610. The tableware carrier cage 10 first moves along the primary cleaning section 1131 to the bottom of the primary cleaning section 1131 and enters the immersion tank 61, driving the tableware on it to immerse in the immersion tank 61 for immersion, and then continues to move along the primary cleaning section 1131 and leaves the immersion tank 61 from the bottom of the primary cleaning section 1131 upward, driving the washed tableware to leave the immersion tank 61. In the process of the tableware carrier cage 10 moving along the primary cleaning section 1131, the tableware carrier cage 10 passes behind the spray pipe 625, and the spray pipe 625 sprays the cleaning liquid from the spray port 629 to the tableware carrier cage 10, spraying and cleaning the tableware loaded on the tableware carrier cage 10, so that the food residues left on the tableware leave the tableware, and the tableware is purified.

[0042] See Figure 2 The secondary spray immersion unit 620 is substantially the same as the primary spray immersion unit 610, except that the cleaning liquid in the immersion pool 61 of the primary spray immersion unit 610 is a mixture of clean water and negative ion water, while the immersion pool of the secondary spray immersion unit 620 uses clean water as the cleaning liquid, which will not be described in detail. The primary cleaning section 1131 of the conveyor chain 11 is the same as the secondary cleaning section 1132, which will not be described in detail. Under the conveyance of the conveyor chain 11, multiple tableware carrying cages 10 are successively immersed in the immersion pool 61 of the primary spray immersion unit 610 and successively receive spraying from the spray cleaning mechanism 62 of the primary spray immersion unit 61, and then successively immersed in the immersion pool of the secondary spray immersion unit 620 and successively receive spraying from the spray cleaning mechanism of the secondary spray immersion unit 620.

[0043] See Figure 2The drying module 7 includes a drying box 71 and a dryer 72 connected to the drying box 71. The drying section 114 of the conveying chain 11 is "U" shaped, and its bottom extends into the drying box 71. The tableware carrier cage 10 moves from the cleaning section 113 of the conveying chain 11 to the drying section 114, that is, from the cleaning module 6 to the drying module 7, and the cleaned tableware is sent into the drying module 7. The tableware carrier cage 10 first moves along the drying section 114 to the bottom of the drying section 114 and enters the drying box 71. The dryer 72 provides hot air to the drying box 71 to dry the cleaned tableware loaded on the tableware carrier cage 10, remove the cleaning liquid on the tableware, and purify the tableware. A vertical guide bar is provided at the drying box 71, and the vertical guide bar can guide the tableware cage 10 entering the drying box 71 so that the tableware cage 10 remains in a nearly vertical state and the cage mouth 100 remains in an upright state facing upwards, which will not be described in detail. The tableware carrying cage 10 continues to move along the drying section 114 and leaves the drying box 71 in an upright state, and delivers the dried tableware to the outside of the drying box 71.

[0044] See Figure 2The tableware automatic purification device is provided with two discharging guide shafts 134 and 135 at the rear of the tableware outlet 102, and the front discharging guide shaft 134 is higher than the rear discharging guide shaft 135. The tableware pouring section 115 of the conveyor chain 11 is divided into a vertical lifting section 1151, a front lower and rear higher inclined section 1152, and a vertical reset section 1153, wherein the lifting section 1151 is located behind the rear discharging guide shaft 135, the inclined section 1152 is located above the front discharging guide shaft 134, and the reset section 1153 is located in front of the front discharging guide shaft 134. Driven by the conveying chain 11, the tableware carrying cage 10 moves forward from the drying section 114 to the lifting section 1151 of the tableware pouring section 115, and then moves from the lifting section 1151 to the inclined section 1152. During this process: the discharge guide shafts 134 and 135 serve as discharge guide parts, and the tableware carrying cage 10 is first guided by the rear discharge guide shaft 135, and rotates clockwise to the upper rear side with the hanging angle 105 as the rotation center to lean against the front discharge guide shaft 134, and then guided by the front discharge guide shaft 134, it continues to rotate clockwise to the upper rear side with the hanging angle 105 as the rotation center to make the cage mouth 100 tilt downward to align with the tableware output port 102, and pour the dried tableware out from the tableware output port 102 in an inverted state. After the tableware is poured out, the tableware carrier cage 10 moves from the inclined section 1152 to the reset section 1153. During this process, the tableware carrier cage 10 is no longer guided by the two material discharging guide shafts 134 and 135, and is in a naturally drooping state. The front end of the transverse support bar 131 extends a front arc-shaped guide bar 1312 toward the front and bottom. The tableware carrier cage 10 moves from the reset section 1153 to the rotation section 119, and is guided by the front arc-shaped guide bar 1312. It rotates counterclockwise to the front upper side with the hanging angle 105 as the rotation center to a horizontal state with the cage mouth 100 facing backward. Its front lower corner 106 and rear lower corner 107 are respectively supported on the transverse support bar 131, and then moves from the rotation section 119 to the tableware receiving section 111 to reload the tableware. It will not be repeated here.

[0045] See Figure 6 In this embodiment, the tableware carrying cage 10 is used as the tableware carrying container, and the tableware carrying cage 10 is provided with a slag discharge port 109 at the bottom and the side. In other embodiments, a tableware box having slag discharge ports only at the front and rear sides may be used instead of the tableware carrying cage 10 as the tableware carrying container, or a tableware clamping rack having open front and rear sides may be used instead of the tableware carrying cage 10 as the tableware carrying container.

[0046] See Figure 2, the conveying mechanism of this embodiment is composed of a conveying chain 11 and a chain drive assembly 12. Other embodiments may use an existing conveying belt to replace the conveying chain 11, and correspondingly, use an existing belt drive assembly to replace the chain drive assembly 12, and the conveying mechanism is composed of a conveying belt and a belt drive assembly. Other embodiments may use other forms of conveying mechanisms, such as using an existing manipulator to clamp the tableware carrier cage 10 and then let the manipulator convey the tableware cage 10 to pass through the tableware delivery port 101, the slag removal module 5, the cleaning module 6, the drying module 7 and the tableware output port 102 in sequence.

[0047] See Figure 3 In this embodiment, the slag removal module 5 is provided with a residue conveying mechanism 53 and a spraying slag removal mechanism 54. In other embodiments, the slag removal module may eliminate one of the mechanisms and retain the other mechanism, for example, eliminating the residue conveying mechanism 53 and retaining the spraying slag removal mechanism 54; or eliminating the spraying slag removal mechanism 53 and retaining the residue conveying mechanism 54.

[0048] See Figure 2 In this embodiment, the tableware purification module includes a slag removal module 5 and a cleaning module 6: the slag removal module 5 removes food residues from the tableware by spraying, and can clean the tableware during the slag removal process, so the slag removal module 5 also serves as a cleaning module; the cleaning module 6 cleans the tableware by spraying and immersing, and can remove the food residues remaining on the tableware, so the cleaning module 6 also serves as a slag removal module. Other embodiments can cancel one of the modules and retain the other module, for example, cancel the slag removal module 5 and retain the cleaning module 6, and the cleaning module 6 also serves as a slag removal module to remove food residues from the tableware during the cleaning process. In other embodiments, the slag removal module 5 can be changed from a liquid spray type slag removal to a jet type slag removal, that is, the slag removal module 5 removes food residues from the tableware by spraying high-pressure gas. Since the slag removal module 5 does not have a "cleaning" effect, it only serves as a slag removal module and not a cleaning module.

[0049] See Figure 2 In this embodiment, the tableware purification module includes a drying module 7. In other embodiments, the tableware purification module can cancel the drying module 7 and replace it with an ultraviolet disinfection module, which is arranged in front of the cleaning module 6 to disinfect and purify the tableware by irradiating the tableware with ultraviolet rays.

[0050] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
