[0002] At present, in large restaurants, especially those in schools, companies, factories, etc., the recycling of tableware is mainly achieved through tableware circulation equipment. Diners first send the tableware to the recycling area. After the tableware is transmitted by the tableware circulation equipment, the staff will separate the leftovers and classify the tableware for recycling.

[0003] At present, the tableware circulation equipment on the market mainly uses a conveyor belt to transport the plates, and the conveyor belt is powered by a motor. However, the existing motor and the conveyor belt are mainly driven by a sprocket chain. For example, the relevant technology discloses a tableware circulation equipment, in which the motor is installed in the driving cabin below the first driving section, and is connected to the sprocket chain through the rotating shaft of the sprocket. However, the plate circulation equipment has the following problems:

[0004] 1. Lubricating grease needs to be applied between the motor and the sprocket chain to reduce friction and ensure transmission efficiency. However, the lubricating grease will evaporate in the tableware recycling and processing space. Daily regular flushing will also cause grease loss, resulting in insufficient lubrication of the sprocket chain and environmental pollution.

[0005] 2. The drive cabin is close to the ground. When the floor of the space is cleaned later, the cleaning fluid can easily seep into the drive cabin and corrode the motor, affecting the service life of the motor. Even during high-pressure flushing, the motor may leak electricity, causing the risk of electric shock to personnel. Summary of the invention

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] Referring to Figures 1 to 3 , a tableware transfer device provided by an embodiment of the present utility model includes a transfer line 100 and a drive assembly 200. The transfer line 100 is built from stainless steel and aluminum profiles. The transfer line 100 includes a drive position 110, a rotary position 120, and a transmission member 130. The drive position 110 and the rotary position 120 are respectively arranged at both ends of the transfer line 100. Both ends of the transmission member 130 are respectively installed at the drive position 110 and the rotary position 120. A flow channel 140 for the transmission member 130 to transfer tableware is formed between the rotary position 120 and the drive position 110. The flow channel 140 is mainly composed of a straight section and a turning section. For the specific structure of the flow channel 140, reference can be made to the applicant's prior application (Patent No. CN202310513908.1), and details will not be elaborated here.

[0030] The drive assembly 200 includes a motor 210 and a speed reducer 220. The speed reducer 220 is fixedly installed at the drive position 110. A gear pair for transmission is sealed inside the speed reducer 220. The motor 210 is connected to the speed reducer 220, and the speed reducer 220 is connected to the transmission member 130, so that the motor 210 is in transmission connection with the transmission member 130 through the speed reducer 220.

[0031] It should be noted that the motor 210 can be connected vertically downward above the speed reducer 220, thereby significantly increasing the installation height of the motor 210. The motor 210 can also be connected vertically upward below the speed reducer 220, thereby maintaining the flatness of the outer shape of the transfer line 100. In short, the motor 210 is directly connected to the speed reducer 220 at the drive position 110, and the ground clearance of the motor 210 (i.e., the distance from the bottom surface of the motor 210 to the ground) is usually greater than or equal to 50 cm.

[0032] It can be understood that the motor 210 drives the transmission member 130 through the speed reducer 220, eliminating the traditional synchronous belt structure. Combining with the housing structure of the speed reducer 220 itself, the lubricating grease is locked inside the speed reducer 220, avoiding the volatilization pollution of the lubricating grease and the loss of grease during flushing, and improving the green environmental protection of the tableware transfer equipment; both ends of the speed reducer 220 and the transmission member 130 are arranged at the driving position 110, that is, the speed reducer 220 and the transmission member 130 are basically at the same height. The motor 210 is directly connected to the speed reducer 220 at the driving position 110, not only eliminating the traditional driving cabin structure and simplifying the structure of the tableware transfer equipment, but also greatly increasing the ground clearance of the motor 210, avoiding the cleaning liquid eroding the motor 210 or causing electric leakage accidents when cleaning the floor of the cleaning treatment space. Moreover, the speed reducer 220 has higher transmission control precision, higher output torque and reliability, which can effectively extend the service life of the motor 210 and improve the use safety of the tableware transfer device.

[0033] Refer to Figure 2 and Figure 3 As shown, it can be understood that the driving position 110 is provided with a bracket 111. The bracket 111 is a right-angle plate with reinforcing ribs. The speed reducer 220 is provided with a connecting portion 222. The connecting portion 222 is structures such as screw holes, clamping blocks, and protrusions arranged on one side of the speed reducer 220. The bracket 111 and the connecting portion 222 are detachably connected by means of screwing, clamping, plugging, etc., which will not be elaborated here.

[0034] By setting the bracket 111, the speed reducer 220 is detachably connected to the bracket 111 through the connecting portion 222. On the premise of ensuring the stable installation of the speed reducer 220, it is convenient for users to assemble, maintain or replace the speed reducer 220, reducing the later maintenance cost of the speed reducer 220.

[0035] Refer to Figure 2 As shown, it can be understood that a cushion block 112 is provided between the bracket 111 and the driving position 110. The cushion block 112 is respectively connected to the bracket 111 and the transfer line 100.

[0036] By setting the cushion block 112, the bottom of the bracket 111 is connected to the transfer line 100 through the cushion block 112, thereby facilitating users to adjust the installation height of the speed reducer 220, and the cushion block 112 can absorb part of the vibration of the speed reducer 220, improving the working stability of the transmission member 130.

[0037] Refer to Figure 3 As shown, it can be understood that corresponding flange structures 211 are respectively provided at the connection between the motor 210 and the speed reducer 220. The motor 210 and the speed reducer 220 are hermetically connected through the flange structures 211.

[0038] By setting the flange structure 211, the sealing performance at the connection between the motor 210 and the reduction gearbox 220 can be effectively improved, which can further prevent the volatilization and overflow of lubricating grease, improve the waterproof performance of the motor 210 and the reduction gearbox 220, and extend the service life of the motor 210.

[0039] Referring to Figure 3 as shown, it can be understood that the reduction gearbox 220 is provided with a hollow shaft 221, a driving shaft 230 is provided between the reduction gearbox 220 and the transmission member 130, and the driving shaft 230 is connected to the transmission member 130 and key-connected to the hollow shaft 221.

[0040] By setting the hollow shaft 221 with a keyway and key-connecting the driving shaft 230 to the reduction gearbox 220, the connection structure between the driving assembly 200 and the transmission member 130 is simplified, the installation stability of the driving shaft 230 is improved, and the transmission efficiency of the motor 210 is ensured.

[0041] Referring to Figure 2 and Figure 3 as shown, it can be understood that the driving position 110 is provided with two first bearing seats 160. The two ends of the driving shaft 230 symmetrically penetrate through the hollow shaft 221 and are connected to the bearings on the first bearing seats 160. Active wheels 231 are respectively installed at the two ends of the driving shaft 230 penetrating through the hollow shaft 221. The rotating position 120 is provided with two second bearing seats. A driven shaft is connected between the two second bearing seats. Two driven wheels are symmetrically installed on the driven shaft. The transmission member 130 includes two transmission belts 131. The two transmission belts 131 are symmetrically arranged on both sides of the reduction gearbox 220, and the transmission belts 131 are respectively connected to the active wheels 231 and the driven wheels correspondingly.

[0042] Due to the use of the reduction gearbox 220 for transmission, the output torque and reliability are higher. The transmission member 130 only needs to be provided with two transmission belts 131. Driven by the reduction gearbox 220, the two transmission belts 131 can achieve a transmission effect similar to that of the four transmission belts 131 of the traditional tableware transfer device. The structure of the transmission member 130 is effectively simplified, and the use cost of the tableware transfer equipment is reduced.

[0043] It should be noted that in some embodiments, the transmission belt 131 is selected as a food-grade elastic O-shaped belt. The O-shaped belt can buffer the load impact, effectively reduce the running noise of the tableware transfer equipment, and the manufacturing and installation accuracy requirements of the O-shaped belt are low and lubrication is not required, which can reduce the later maintenance cost of the transmission member 130.

[0044] Referring to Figure 2 as shown, it can be understood that the driving position 110 is provided with a cover body 113. The cover body 113 is detachably connected to the transfer line 100. The cover body 113 covers the ends of the bracket 111, the reduction gearbox 220 and the transmission member 130. The cover body 113 is provided with a hollow structure for the transmission member 130 to pass through.

[0045] By providing the cover body 113, on the one hand, the cooperation between the cover body 113 and the plate member at the driving position 110 of the transfer line 100 can accommodate structures such as the hidden bracket 111, the reduction gearbox 220, the driving shaft 230, and the driving wheel 231, improving the aesthetic appearance of the tableware transfer device; on the other hand, the cover body 113 covers the end of the transmission member 130, and the transmission member 130 transfers the dinner plate in the flow channel 140. Therefore, the height of the cover body 113 in the vertical direction is higher than the upper surface of the transmission member 130. At this time, the cover body 113 can play a limiting role to restrict the continuous movement of the tableware on the transmission member 130 and prevent the tableware from flowing out of the flow channel 140, improving the convenience of use of the tableware transfer device.

[0046] Preferably, the cover body 113 includes a frame 1131 and a cover plate 1132. The frame 1131 is installed at the driving position 110 and is arranged around the bracket 111, the reduction gearbox 220, and the end of the transmission member 130. An opening is provided at the top of the frame 1131, and the cover plate 1132 is detachably connected to the frame 1131 through cooperation methods such as screwing, clamping, and pinning. The cover plate 1132 is used to close the opening.

[0047] By providing the detachable cover plate 1132, when the user removes the cover plate 1132, the user can directly observe the conditions of components such as the bracket 111, the reduction gearbox 220, the driving shaft 230, and the transmission member 130 at the driving position 110, facilitating the user to load, unload, repair, or replace each component at the driving position 110, further improving the convenience of use of the tableware transfer device and reducing the later maintenance cost of the tableware transfer device.

[0048] Referring to Figure 1 and Figure 4 As shown, it can be understood that the transfer line 100 is provided with a filter plate 141. The filter plate 141 is located at one end of the flow channel 140 close to the driving position 110. The filter plate 141 can be arranged in the flow channel 140, or above or below the flow channel 140, which will not be elaborated here. The transfer line 100 is provided with a water tank 150. The water tank 150 is located below the filter plate 141 and on one side of the driving assembly 200. The water tank 150 is also provided with a hollow structure for the transmission member 130 to pass through, which will not be elaborated here. In addition, a water outlet pipe 151 is usually provided at the bottom end of the water tank 150, and the water outlet pipe 151 is connected to an external water storage member, such as a water bucket, a pool, etc.

[0049] Since the motor 210 is directly connected to the reduction gearbox 220, structures such as the drive compartment and the timing belt are omitted, thereby expanding the installation space below the drive position 110, eliminating the interference avoidance problem between the water tank 150 and the drive compartment existing in the traditional tableware transfer device, facilitating the user to set a relatively large water tank 150 in this installation space, and improving the assembly convenience of the water tank 150. The water tank 150 cooperates with the filter plate 141, so that the cleaning liquid for the washed tableware flows out of the water tank 150 through the water outlet pipe 151 after being filtered, recycling the liquid used for washing the tableware, further improving the green environmental protection of the tableware transfer device, and reducing the use cost of the tableware transfer device.

[0050] Referring to Figure 4 as shown, it can be understood that the water tank 150 is connected with a drawer-like pull-out member 152. The pull-out member 152 is located between the filter plate 141 and the water outlet pipe 151. The pull-out member 152 is slidably connected to the water tank 150 and can extend or retract relative to the water tank 150. The bottom surface of the pull-out member 152 is provided with filter holes.

[0051] By providing the pull-out member 152 with filter holes, the liquid recovered in the water tank 150 is secondarily filtered to improve the cleanliness of the recovered liquid. In addition, since the drive compartment is omitted, the hinge door used to open and close the drive compartment in the traditional tableware transfer device is also removed synchronously. At this time, there is no obstruction outside the water tank 150, facilitating the user to directly move the pull-out member 152 and effectively improving the user experience.

[0052] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
