[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Example: Reference Figures 1-10 A food conveying device that is easy to clean includes a base plate 101, a cleaning pool 105 is fixedly installed on the base plate 101, conveying cylinders 107 are symmetrically mounted on the base plate 101 for rotation, a conveyor belt 106 is arranged between the two conveying cylinders 107, a driving motor 104 is fixedly installed on the base plate 101, and the output shaft of the driving motor 104 is fixedly connected to the corresponding conveying cylinder 107. When the driving motor 104 is started, the corresponding conveying cylinder 107 is driven to rotate. Under the action of the conveying cylinder 107, the conveyor belt 106 rotates, and the food is placed on the upper surface of the conveyor belt 106 for transportation.

[0026] The bottom plate 101 is provided with a pressing assembly, which includes a pressing cylinder 123, on which an annular scraper 120 is provided, and the pressing cylinder 123 is used to enable the conveyor belt 106 to enter the cleaning tank 105 for cleaning. The pressing assembly also includes a pressing slide 115 slidably mounted on the cleaning tank 105, and the pressing cylinder 123 is rotatably mounted on the pressing slide 115. A pressing screw rod 113 is rotatably mounted on the cleaning tank 105, and the pressing screw rod 113 and the pressing slide 115 constitute a spiral pair, which cleans the conveyor belt 106. A downward pressure motor 112 is fixedly installed on the washing tank 105, and the output shaft of the downward pressure motor 112 is fixedly connected to the downward pressure screw rod 113. The downward pressure cylinder 123 is located on the inner side of the conveyor belt 106. A support plate 2 128 is fixedly installed on the inner side of the downward pressure slide 115. The annular scraper 120 on the downward pressure cylinder 123 is slidably installed on the support plate 2 128. A limiting long plate 2 121 is also fixedly installed on the washing tank 105. When the annular scraper 120 on the downward pressure cylinder 123 and the limiting long plate 2 121 are engaged, the two are slidably connected.

[0027] In the initial position, the limiting long plate 121 and the annular scraper 120 on the pressing cylinder 123 are in an engaged state. At this time, the annular scraper 120 on the pressing cylinder 123 is located at the position closest to the pressing motor 112, and at this time, the pressing slide 115 is located at the position closest to the lower surface of the base plate 101, that is, the pressing cylinder 123 is located at the position closest to the lower surface of the base plate 101. Under the action of the pressing cylinder 123, the contact part of the conveyor belt 106 and the pressing cylinder 123 is located in the cleaning water in the cleaning tank 105, driving the conveyor belt 106 to rotate, that is, the conveyor belt 106 continuously passes through the cleaning water in the cleaning tank 105, thereby achieving the cleaning of the conveyor belt 106.

[0028] Start the downward pressing motor 112 to drive the downward pressing screw rod 113 to rotate, so that the downward pressing slide 115 can move up and down relative to the base plate 101.

[0029] A cleaning scraper 124 is fixedly installed on the inside of the cleaning tank 105. The cleaning scraper 124 is located directly below the pressing cylinder 123. The cleaning scraper 124 is used to scrape and clean the attachments on the surface of the conveyor belt 106.

[0030] When the downward pressure cylinder 123 is located at the position closest to the lower surface of the base plate 101, the cleaning scraper 124 is in contact with the surface of the conveyor belt 106. During the movement of the conveyor belt 106, the cleaning scraper 124 scrapes and cleans the attachments on the surface of the conveyor belt 106, thereby improving the cleaning effect of the conveyor belt 106.

[0031] The bottom plate 101 is provided with an extrusion assembly, which includes a support cylinder 125 and two extrusion cylinders 117. The extrusion cylinder 117 and the support cylinder 125 are used to squeeze and discharge the moisture on the conveyor belt 106. The extrusion cylinder 117 and the support cylinder 125 are movably provided with an annular scraper 120. The extrusion assembly also includes an extrusion slide 114 slidably mounted on the cleaning tank 105. The cleaning tank 105 is rotatably provided with an extrusion screw 111. The extrusion screw 111 and the extrusion slide 114 constitute a spiral pair. The cleaning tank 105 is fixedly provided with an extrusion motor 110. The output shaft of the pressure motor 110 is fixedly connected to the extrusion screw 111, and the two extrusion cylinders 117 are symmetrically mounted on the extrusion slide 114. The extrusion cylinders 117 are also located on the inner side of the conveyor belt 106. A support plate 119 is fixedly provided on the extrusion slide 114, and a linkage slide 130 is slidably installed on the support plate 119. The annular scrapers 120 on the two extrusion cylinders 117 are fixedly connected to the linkage slide 130. A limiting long plate 116 is also fixedly installed on the inner side of the cleaning tank 105. When the linkage slide 130 and the limiting long plate 116 are engaged, the two are slidably connected.

[0032] A scraping slide 102 is slidably mounted on the base plate 101, and a feed screw 109 is rotatably mounted on the base plate 101. The feed screw 109 and the scraping slide 102 constitute a spiral pair. A feed motor 108 is fixedly mounted on the base plate 101, and the output shaft of the feed motor 108 is fixedly connected to the feed screw 109. The annular scrapers 120 on the two conveying cylinders 107 are both fixedly connected to the scraping slide 102. A U-shaped yield plate 103 is also fixedly mounted on the scraping slide 102. The support cylinder 125 is rotatably mounted on the cleaning tank 105, and the annular scraper 120 on the pressing cylinder 123 is fixedly mounted on the U-shaped yield plate 103. The support cylinder 125 is located below the conveying cylinder 107.

[0033] In the initial position, the scraping slide 102 is located at the position closest to the feed motor 108, the limiting long plate 116 and the linkage slide 130 are in an engaged state, and the annular scrapers 120 on the scraping slide 102 are all located at the position closest to the feed motor 108, and the extrusion slide 114 is located at the position closest to the lower surface of the base plate 101. At this time, the axis of the extrusion cylinder 117 is located below the axis of the support cylinder 125 and above the axis of the downward pressure cylinder 123. Under the action of the two extrusion cylinders 117, the conveyor belt 106 is in a straight state, and under the action of the extrusion cylinder 117 and the support cylinder 125, the moisture carried on the conveyor belt 106 after cleaning in the cleaning tank 105 is squeezed out, and the part of the conveyor belt 106 below the extrusion cylinder 117 is located above the cleaning tank 105.

[0034] Starting the extrusion motor 110 to drive the extrusion screw 111 to rotate can make the extrusion slide 114 move up and down relative to the base plate 101, and the extrusion cylinder 117 on the extrusion slide 114 moves synchronously, and the linkage slide 130 slides relative to the limiting long plate 116. When the linkage slide 130 disengages and contacts the downward pressing slide 115, the linkage slide 130 slides relative to the support plate 119, that is, the linkage slide 130 slides along the axis of the extrusion cylinder 117, and the two annular scrapers 120 on the linkage slide 130 slide synchronously, and the annular scrapers 120 on the linkage slide 130 clean the attachments on the corresponding extrusion cylinders 117 respectively.

[0035] Start the feed motor 108 to drive the feed screw 109 to rotate, so that the scraper slide 102 moves away from the feed motor 108, and the annular scraper 120 on the scraper slide 102 moves synchronously, so that the annular scraper 120 on the conveying cylinder 107 scrapes and cleans the attachments on the surface of the conveying cylinder 107, and the annular scraper 120 on the supporting cylinder 125 scrapes and cleans the attachments on the surface of the supporting cylinder 125.

[0036] A linkage short plate 122 and a linkage short plate 2 129 are fixedly provided on the scraping slide 102. The projections of the linkage short plate 122 and the limiting long plate 116 on the lower surface of the base plate 101 overlap. When the linkage short plate 122 and the linkage slide plate 130 are engaged, the two are slidingly connected. The projections of the linkage short plate 2 129 and the limiting long plate 2 121 on the lower surface of the base plate 101 overlap. When the linkage short plate 2 129 and the annular scraper 120 on the lower pressure cylinder 123 are engaged, the two are slidingly connected.

[0037] Start the extrusion motor 110 and the pressing motor 112, so that the extrusion slide 114 and the pressing slide 115 are moved to the position farthest from the lower surface of the base plate 101. At this time, the axes of the extrusion cylinder 117 and the pressing cylinder 123 are on the same plane, and the plane where the axes of the extrusion cylinder 117 and the pressing cylinder 123 are located is above the supporting cylinder 125. The linkage slide 130 and the linkage short plate 1 122 are engaged, and the annular scraper 120 on the pressing cylinder 123 is engaged with the linkage short plate 2 129. When the scraping slide 102 is driven to move away from the feed motor 108, under the action of the linkage short plate 122 and the linkage short plate 2 129, the linkage slide 130 and the annular scraper 120 on the pressing cylinder 123 move synchronously, and the annular scrapers 120 on the conveying cylinder 107, the extrusion cylinder 117, the pressing cylinder 123 and the support cylinder 125 all move synchronously, thereby cleaning the attachments on the surfaces of the conveying cylinder 107, the extrusion cylinder 117, the pressing cylinder 123 and the support cylinder 125.

[0038] An expansion assembly is provided on the base plate 101, and the expansion assembly includes an auxiliary slide 131. The auxiliary slide 131 is slidably mounted on the base plate 101, and an auxiliary screw rod 133 is rotatably mounted on the auxiliary slide 131. The auxiliary screw rod 133 and the base plate 101 form a spiral pair, and an auxiliary motor 132 is fixedly mounted on the auxiliary slide 131. The output shaft of the auxiliary motor 132 is fixedly connected to the auxiliary screw rod 133, and the axis of the auxiliary screw rod 133 is parallel to the axis of the conveying cylinder 107. Starting the auxiliary motor 132 to drive the auxiliary screw rod 133 to rotate can make the auxiliary slide 131 move along the axis of the conveying cylinder 107.

[0039] A second spreading slide 138 is symmetrically and slidingly installed on the auxiliary slide 131, and a double-headed threaded screw rod 139 is rotatably installed on the auxiliary slide 131. The threads at both ends of the double-headed threaded screw rod 139 respectively form a spiral pair with the corresponding spreading slide 138. A second spreading motor 140 is fixedly installed on the auxiliary slide 131. The output shaft of the spreading motor 140 is fixedly connected to the double-headed threaded screw rod 139. The axis of the double-headed threaded screw rod 139 is perpendicular to the lower surface of the base plate 101. Starting the spreading motor 140 to drive the double-headed threaded screw rod 139 to rotate can make the two spreading slides 138 move away from each other or move towards each other.

[0040] The stretching strips 126 are symmetrically and slidably installed on the stretching slide 138, and the auxiliary slide 131 is also symmetrically provided with a stretching slide 137. The stretching slide 137 slides with the two stretching strips 126 on the same side respectively. A double-headed threaded screw 136 is rotatably installed on the auxiliary slide 131. The threads at both ends of the double-headed threaded screw 136 form a spiral pair with the corresponding stretching slide 137 respectively. An stretching motor 118 is fixedly installed on the auxiliary slide 131. The output shaft of the stretching motor 118 is fixedly connected to the double-headed threaded screw 136. When the stretching motor 118 is started, the double-headed threaded screw 136 is driven to rotate, so that the two stretching slides 137 move away from each other or towards each other, and the stretching strips 126 on the stretching slide 137 move synchronously, that is, the two stretching strips 126 on the same stretching slide 138 move away from each other or towards each other.

[0041] A long expansion rod 141 is fixedly provided on the expansion strip 126. The long expansion rod 141 is located at the end of the expansion strip 126 farthest from the axis of the double-headed threaded screw 139. The long expansion rod 141 is used to separate the conveyor belt 106 from contact with the conveyor cylinder 107 when cleaning the conveyor cylinder 107.

[0042] In the initial position, the auxiliary slide 131 is located at the position closest to the scraper slide 102, the two spreading slides 138 are located at the position closest to each other, and the two spreading slides 137 are located at the position closest to each other, so that the four spreading long rods 141 are located at the position closest to each other. At this time, the spreading long rods 141 are not in contact with the conveyor belt 106, and the spreading long rods 141 are not in the position between the two conveying cylinders 107.

[0043] When it is necessary to clean the attachments on the surface of the conveying cylinder 107, the extrusion cylinder 117, the pressing cylinder 123, and the supporting cylinder 125, the second spreading motor 140 is started to make the two spreading slides 138 move away from each other, the spreading strips 126 on the second spreading slide 138 move, and the spreading long rods 141 on the spreading strips 126 also move synchronously, that is, the two spreading long rods 141 on the same side move away from each other, and the spreading long rods 141 both contact the surface of the conveyor belt 106, and finally the two spreading long rods 141 on the same side move to the farthest position. , that is, to realize the expansion of the conveyor belt 106, and then start the expansion motor 118 to drive the double-headed threaded screw 136 to rotate, so that the two expansion slides 137 move away from each other, and the two expansion strips 126 corresponding to the expansion slide 137 move synchronously, thereby making the two expansion long rods 141 on the same expansion slide 138 move away from each other, and finally making the two expansion long rods 141 on the same expansion slide 138 move to the farthest position. At this time, the conveyor belt 106 is separated from the contact with the conveying cylinder 107 under the action of the expansion long rod 141.

[0044] In the process of stretching the long rod 141 to stretch the conveyor belt 106, the extrusion motor 110 and the pressing motor 112 are started synchronously, so that the extrusion cylinder 117 and the pressing cylinder 123 are moved upward, thereby supplementing the length of the conveyor belt 106 required for stretching the long rod 141 to stretch the conveyor belt 106. When the long rod 141 is fully stretched to stretch the conveyor belt 106, the conveying cylinder 107, the extrusion cylinder 117, the pressing cylinder 123 and the supporting cylinder 125 are not in contact with the conveyor belt. 106 is in contact, and the scraping slide 102 is started to drive the feed motor 108 to move, so that the scraping slide 102 can scrape and clean the attachments on the conveying cylinder 107, the extrusion cylinder 117, the pressing cylinder 123, and the supporting cylinder 125. Under the action of the U-shaped yield plate 103, when the annular scraper 120 on the supporting cylinder 125 moves, the conveyor belt 106 is located in the depression of the U-shaped yield plate 103, that is, the U-shaped yield plate 103 gives way to the conveyor belt 106.

[0045] The long supporting rod 141 is movably provided with a round-head scraper 127, which is used to clean the attachments on the long supporting rod 141. L-shaped slides 134 are symmetrically slidably installed on the bottom plate 101, and C-shaped slides 135 are fixedly provided on the L-shaped slides 134. The C-shaped slides 135 are respectively slidably matched with the two round-head scrapers 127 on the same side.

[0046] When the two spreading long rods 141 on the same side move away from each other, the round-head scrapers 127 corresponding to the two spreading long rods 141 also move away from each other, and the round-head scrapers 127 slide relative to the C-shaped slide 135. When the two spreading long rods 141 on the same spreading slide 138 move away from each other, the two C-shaped slides 135 also move away from each other, that is, the two L-shaped slides 134 move away from each other. Under the action of the L-shaped slide 134 and the C-shaped slide 135, the round-head scraper 127 can move synchronously with the spreading long rod 141.

[0047] Before the stretching long rod 141 stretches the conveyor belt 106, the auxiliary motor 132 is started first to move the auxiliary slide 131 away from the scraping slide 102, and the four stretching long rods 141 move synchronously. At this time, the stretching long rod 141 slides relative to the round-head scraper 127, that is, under the action of the round-head scraper 127, the attachments on the surface of the stretching long rod 141 are cleaned first.

[0048] Working principle: Start the drive motor 104, and under the action of the conveying cylinder 107, the extrusion cylinder 117, the downward pressure cylinder 123, and the support cylinder 125, the conveyor belt 106 is used to transport food. When the conveyor belt 106 passes the position of the downward pressure cylinder 123, the cleaning pool 105 and the cleaning scraper 124 are used to scrape and clean the attachments on the surface of the conveyor belt 106. After cleaning, the conveyor belt 106 passes the position of the support cylinder 125 and the two extrusion cylinders 117, and the water carried on the conveyor belt 106 is squeezed out under the action of the support cylinder 125 and the two extrusion cylinders 117.

[0049] After the device has been working for a long time, the attachments accumulated on the conveying cylinder 107, the extruding cylinder 117, the pressing cylinder 123 and the supporting cylinder 125 will affect the stability and sanitary quality of the food conveyed by the conveyor belt 106. Therefore, when it is necessary to clean the attachments on the conveying cylinder 107, the extruding cylinder 117, the pressing cylinder 123 and the supporting cylinder 125, the auxiliary motor 132 is first started to drive the auxiliary slide 131 to move, so that the spreading long rod 141 slides relative to the round-head scraper 127, that is, the attachments on the surface of the spreading long rod 141 are scraped and cleaned. Then the auxiliary slide 131 returns to the initial position, and the stretching long rod 141 stretches the conveyor belt 106. At the same time, the downward pressure cylinder 123 and the downward pressure slide 115 are driven to move upward, contacting the conveyor belt 106 to press the conveyor belt 106, thereby supplementing the length required for the stretching long rod 141 to stretch the conveyor belt 106. After the stretching long rod 141 completely stretches the conveyor belt 106, the scraping slide 102 is started, so that the annular scraper 120 scrapes and cleans the attachments on the conveying cylinder 107, the extrusion cylinder 117, the downward pressure cylinder 123, and the support cylinder 125.

[0050] The present invention is not limited to the above-mentioned specific embodiments. Various modifications made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
