[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0017] like Figure 1 The diagram shows the structure of the spiral cross-type logistics conveyor of the present invention. It is typically used for logistics conveying and sorting, and includes a track 1, a conveying structure 2, a loading structure 3, and a unloading structure 4. The track 1 is spirally closed, and the spiral upward design results in higher sorting efficiency and a smaller footprint. The loading structure 3 conveys packages to the conveying structure 2, which moves along the track 1, thereby sorting the packages into the corresponding slots of the unloading structure 4 as required.

[0018] like Figure 2-4The diagram shows the structure of track 1. Track 1 consists of a main track and connecting tracks. The main track is arranged in a spiral upward pattern, which improves sorting efficiency and reduces the footprint. The connecting tracks connect adjacent main tracks, as well as the top and bottom main tracks, thus forming a closed structure for track 1, facilitating the circulation of the conveyor structure 2 along track 1.

[0019] The main track consists of straight rails, transition rails, and curved rails, such as... Figure 5 , 6 The diagram shows the structure of the straight rail, which includes a straight rail frame 101, a straight rail inclined sealing plate 102, a straight rail top plate 103, and a straight rail side plate 104. Multiple straight rail frames 101 are fixed to the top of the gantry frame at intervals by screws or welding. The straight rail inclined sealing plate 102 is fixed to the outside of the straight rail frame 101, used to fix and connect the multiple straight rail frames 101 at the top of the gantry frame, thus connecting the straight rail frames 101 into a whole and improving the structural strength of the straight rail frame 101.

[0020] There are two top rail plates 103, fixed at intervals on the top of the straight rail frame 101. The top rail plates 103 are horizontally arranged. When the sorting trolley is transporting and sorting packages, the outer abutment wheel 205 of the sorting trolley presses against the upper surface of the top rail plate 103. There are two side rail plates 104, fixed to the inner sides of the two top rail plates 103 respectively. When the sorting trolley is transporting and sorting packages, the inner abutment wheel 206 of the sorting trolley presses against the inner surface of the side rail plate 104.

[0021] An "L"-shaped protective cover is fixed to the top of the opposite side of the straight rail top plate 103 to protect the outer stop wheel 205 and the inner stop wheel 206, preventing foreign objects from entering and affecting the normal movement of the sorting trolley.

[0022] There are multiple straight rails, which are fixed together by screws to form a long straight rail, such as... Figure 2-4 The first and second layers of long straight rails shown are both formed by multiple straight rails fixedly connected together.

[0023] like Figure 7 , 8 The diagram shows the structure of the curved track, which includes a curved track frame 105, a curved track inclined sealing plate 106, a curved track outer top plate 107, a curved track outer side plate 108, a curved track inner top plate 109, and a curved track inner side plate 110. Because the main track is spiral-shaped, it appears as a rounded rectangle from a top-down view. The rounded corners on both sides of the main track are formed by the curved track, ensuring that the main track forms a closed, cyclical structure.

[0024] Multiple curved rail frames 105 are fixed to the top of the gantry frame by screws or welding. Curved rail oblique sealing plates 106 are fixed to the inner and outer sides of the curved rail frames 105, used to securely connect the multiple curved rail frames 105 at the top of the gantry frame, thus connecting the curved rail frames 105 into a single unit and improving the structural strength of the curved rail frames 105. The curved rail oblique sealing plates 106 are arc-shaped, therefore, the curved rail frames 105 and the curved rail oblique sealing plates 106 are fixed together to form an arc-shaped frame, forming the rounded corners on both sides of the main track.

[0025] The outer top plate 107 and the inner top plate 109 of the curved rail are respectively fixed to the top of the curved rail frame 105, with the outer top plate 107 near the outer ring and the inner top plate 109 near the inner ring. The outer side plate 108 of the curved rail is fixed to the side of the outer top plate 107 near the inner top plate 109 and is arc-shaped to adapt to the arc-shaped trajectory of the sorting trolley. The inner side plate 110 of the curved rail is fixed to the side of the inner top plate 109 near the outer top plate 107 and is arc-shaped to adapt to the arc-shaped trajectory of the sorting trolley.

[0026] like Figure 8 As shown, the side of the outer top plate 107 of the curved rail away from the outer side plate 108 of the curved rail is higher than the side of the outer top plate 107 of the curved rail near the outer side plate 108 of the curved rail, that is, the outer ring of the outer top plate 107 of the curved rail is higher than the inner ring; the side of the inner top plate 109 of the curved rail near the inner side plate 110 of the curved rail is higher than the side of the inner top plate 109 of the curved rail away from the inner side plate 110 of the curved rail, that is, the outer ring of the inner top plate 109 of the curved rail is higher than the inner ring.

[0027] When the sorting trolley is transporting and sorting packages, the outer abutment wheel 205 of the sorting trolley presses against the outer top plate 107 and the inner top plate 109 of the curved track, and the inner abutment wheel 206 of the sorting trolley presses against the outer side plate 108 and the inner side plate 110 of the curved track. Since the outer side plate 108 and the inner side plate 110 of the curved track are both arc-shaped, they are adapted to the arc-shaped trajectory of the sorting trolley.

[0028] There are multiple curved rails, which are fixed together by screws to form a... Figure 3 The long curved track at the corner shown is used by the sorting trolley to transport and sort packages. The sorting trolley passes through the long curved track on one side and enters the long straight track on the other side.

[0029] like Figure 8 As shown, the outer ring of the outer top plate 107 of the curved track is higher than the inner ring, and the outer ring of the inner top plate 109 of the curved track is higher than the inner ring. Therefore, when the sorting trolley enters the long curved track from the long straight track, the outer ring of the sorting trolley is higher than the inner ring to counteract the centrifugal force when the sorting trolley turns, and to prevent the packages on the sorting trolley from being thrown off the sorting trolley under the action of centrifugal force when the sorting trolley turns.

[0030] The top of the outer top plate 107 and the inner top plate 109 of the curved rail are fixed with an arc-shaped protective cover with an "L"-shaped cross section to protect the outer stop wheel 205 and the inner stop wheel 206, and prevent foreign objects from entering and affecting the normal movement of the sorting trolley.

[0031] Transition rails are used to connect long straight rails and long curved rails because the sorting trolleys follow different trajectories on these two tracks, requiring transition rails to handle trajectory changes. For example... Figure 9-12 As shown, the transition rail includes a transition rail frame 111, a transition rail inclined sealing plate 112, a transition rail outer top plate 113, a transition rail outer side plate 114, a transition rail inner top plate 115, and a transition rail inner side plate 116.

[0032] There are multiple transition rail frames 111, which are fixed to the top of the gantry frame by screws or welding. The transition rail inclined sealing plate 112 is fixed on the inner and outer sides of the transition rail frame 111, and is used to fix and connect the multiple transition rail frames 111 on the top of the gantry frame, so that the transition rail frames 111 are fixedly connected into a whole, thereby improving the structural strength of the transition rail frame 111.

[0033] The outer top plate 113 and the inner top plate 115 of the transition rail are respectively fixed to the top of the transition rail frame 111 and are arranged opposite to each other. The outer side plate 114 of the transition rail is fixed to the side of the outer top plate 113 of the transition rail near the inner top plate 115 of the transition rail, and the inner side plate 116 of the transition rail is fixed to the side of the inner top plate 115 of the transition rail near the outer top plate 113 of the transition rail.

[0034] like Figure 10-12 As shown, the outer top plate 113 of the transition rail is not horizontally set. The side of the outer top plate 113 of the transition rail closer to the straight rail is lower than the side of the outer top plate 113 of the transition rail closer to the curved rail. One side of the outer top plate 113 of the transition rail is tangent to the top plate 103 of the straight rail, and the other side of the outer top plate 113 of the transition rail is tangent to the outer top plate 107 of the curved rail. That is, the outer top plate 113 of the transition rail is set in an inclined and twisted manner.

[0035] The side of the inner top plate 115 of the transition rail closer to the straight rail is higher than the side of the inner top plate 115 of the transition rail closer to the curved rail, and one side of the inner top plate 115 of the transition rail is tangent to the top plate 103 of the straight rail, while the other side of the inner top plate 115 of the transition rail is tangent to the inner top plate 109 of the curved rail. That is, the inner top plate 115 of the transition rail is set in an inclined and twisted manner.

[0036] When the sorting trolley moves from the straight track to the curved track, its trajectory is changed via the transition track. When the sorting trolley is transporting packages, the outer abutment wheel 205 of the sorting trolley abuts against the outer top plate 113 and the inner top plate 115 of the transition track.

[0037] The outer side plate 114 of the transition rail is fixed to the outer top plate 113 of the transition rail near the inner top plate 115 of the transition rail, and the inner side plate 116 of the transition rail is fixed to the inner top plate 115 of the transition rail near the outer top plate 113 of the transition rail. When the sorting trolley is transporting packages, the inner abutment wheel 206 of the sorting trolley abuts against the outer side plate 114 and the inner top plate 115 of the transition rail.

[0038] like Figure 12 As shown, the outer side plate 114 and the inner side plate 116 of the transition rail are not straight plates, but are respectively matched with the tracks of the outer top plate 113 and the inner top plate 115 of the transition rail. Because the outer abutment wheel 205 and the inner abutment wheel 206 are 90° apart, the outer abutment wheel 205 gradually changes its angle when changing tracks. Therefore, the inner abutment wheel 206 needs to be twisted at a certain angle along the outer side plate 114 and the inner side plate 116 of the transition rail.

[0039] like Figure 3 As shown, Figure 3 The left part is a long straight rail, the right part is a long curved rail, and the transition rail connects the long straight rail and the long curved rail. When the sorting trolley transports packages on the straight rail, the outer abutment wheel 205 of the sorting trolley presses against the horizontally set top plate 103 of the straight rail, and the inner abutment wheel 206 of the sorting trolley presses against the side plate 104 of the straight rail. At this time, the outer abutment wheel 205 and the inner abutment wheel 206 of the sorting trolley roll in the same plane.

[0040] When the sorting trolley enters the transition rail, the outer abutment wheel 205 of the sorting trolley enters the outer top plate 113 and inner top plate 115 of the transition rail from the top plate 103 of the straight rail. Since the side of the outer top plate 113 of the transition rail closer to the straight rail is lower than the side of the outer top plate 113 closer to the curved rail, the outer abutment wheel 205 of the outer ring of the sorting trolley will gradually rise. Since the side of the inner top plate 115 of the transition rail closer to the straight rail is higher than the side of the inner top plate 115 closer to the curved rail, the outer abutment wheel 205 of the inner ring of the sorting trolley will gradually descend to ensure that the sorting trolley is in an inclined state with the outside higher than the inside when entering the curved rail. When the sorting trolley enters the long curved rail, the outer ring of the sorting trolley is higher than the inside to counteract the centrifugal force when the sorting trolley turns, and to prevent the packages on the sorting trolley from being thrown off the sorting trolley under the action of centrifugal force when turning.

[0041] When the sorting trolley slides out of the long curved track and into the long straight track on the other side, the sorting trolley inside the long curved track is higher on the outside and lower on the inside. At this time, the sorting trolley will re-enter the transition track, thereby changing the state of the sorting trolley and ensuring that the sorting trolley entering the long straight track returns to a horizontal state.

[0042] like Figure 4As shown, the main track is set in a spiral upward manner. At the bends of the main track, transition rails and curved rails are set to change the trajectory of the sorting trolley. Due to the height difference between two adjacent main tracks and between the top and bottom main tracks, it is necessary to connect the main tracks with different height differences through climbing inner rails and climbing outer rails.

[0043] like Figure 13 As shown, the climbing inner rail includes a climbing inner rail frame 117, a climbing inner rail inclined sealing plate 118, a climbing inner rail top plate 119, and a climbing inner rail side plate 120. There are multiple climbing inner rail frames 117, which are fixed to the top of the gantry frame at intervals by screws or welding. The climbing inner rail inclined sealing plate 118 is fixed to the outside of the climbing inner rail frame 117, used to fix and connect the multiple climbing inner rail frames 117 on the top of the gantry frame, so that the climbing inner rail frames 117 are fixedly connected into a whole, thereby improving the structural strength of the climbing inner rail frame 117.

[0044] There are two top plates 119 for the inner ramp rail, which are fixed to the top of the inner ramp rail frame 117. The side plates 120 for the inner ramp rail are fixed to the inner side of the top plates 119. When the sorting trolley is transporting packages, the outer abutment wheel 205 of the sorting trolley abuts against the top plate 119, and the inner abutment wheel 206 of the sorting trolley abuts against the side plates 120. An arc-shaped protective cover with an "L"-shaped cross-section is fixed to the top of the opposite side of the top plate 119 to protect the outer abutment wheel 205 and the inner abutment wheel 206 and prevent foreign objects from entering and affecting the normal movement of the sorting trolley.

[0045] like Figure 13 As shown, the top plate 119 of the climbing inner rail is arc-shaped with its center of curvature facing upwards. Therefore, when the sorting trolley enters the climbing inner rail from the long straight rail, the sorting trolley will gradually move upwards.

[0046] like Figure 14 As shown, the climbing outer rail includes a climbing outer rail frame 121, a climbing outer rail inclined sealing plate 122, a climbing outer rail top plate 123, and a climbing outer rail side plate 124. There are multiple climbing outer rail frames 121, which are fixed to the top of the gantry frame at intervals by screws or welding. The climbing outer rail inclined sealing plate 122 is fixed to the outside of the climbing outer rail frame 121 and is used to fix and connect the multiple climbing outer rail frames 121 on the top of the gantry frame, so that the climbing outer rail frames 121 are fixedly connected into a whole, thereby improving the structural strength of the climbing outer rail frame 121.

[0047] There are two outer rail top plates 123, which are fixed to the top of the outer rail frame 121. The outer rail side plates 124 are fixed to the inner side of the outer rail top plates 123. When the sorting trolley is transporting packages, the outer abutment wheel 205 of the sorting trolley abuts against the outer rail top plate 123, and the inner abutment wheel 206 of the sorting trolley abuts against the outer rail side plates 124. An arc-shaped protective cover with an "L"-shaped cross-section is fixed to the top of the opposite side of the outer rail top plate 123 to protect the outer abutment wheel 205 and the inner abutment wheel 206 and prevent foreign objects from entering and affecting the normal movement of the sorting trolley.

[0048] like Figure 14 As shown, the top plate 123 of the ramp outer rail is arc-shaped with its center facing downwards. Therefore, after the ascending sorting trolley passes the ramp outer rail, it enters the transition rail and curved rail of the second main rail horizontally.

[0049] like Figure 15 As shown, the conveyor structure 2 includes a vehicle body 201, an electric roller 202, a sorting belt 203, a frame 204, outer abutment wheels 205, inner abutment wheels 206, a support plate 207, a magnetic plate 208, and a permanent magnet linear motor 209. There are multiple vehicle bodies 201, and adjacent vehicle bodies 201 are connected by spherical bearings. There are two electric rollers 202, spaced apart between the vehicle bodies 201. The sorting belt 203 is wound around the electric rollers 202. When the electric rollers 202 rotate, they drive the sorting belt 203 to rotate, thereby sorting the packages into the corresponding compartments.

[0050] The support plate 207 is fixed between the vehicle bodies 201 and abuts against the bottom inner side of the sorting belt 203 to lift the sorting belt 203 upward and prevent the sorting belt 203 from being deformed by pressure when transporting sorted packages.

[0051] The frame 204 is fixed to one side of the body 201. There are two outer abutment wheels 205, which are rotatably mounted on the outside of the frame 204 via a pivot and are vertically arranged. When the sorting trolley moves, the outer abutment wheels 205 roll against the surfaces of the straight rail top plate 103, the transition rail outer top plate 113, the transition rail inner top plate 115, the curved rail outer top plate 107, the curved rail inner top plate 109, the climbing inner rail top plate 119, and the climbing outer rail top plate 123.

[0052] There are two inner abutment wheels 206, which are rotatably mounted on the inner side of the frame 204 via a pivot and are horizontally positioned. When the sorting trolley moves, the inner abutment wheels 206 roll against the inner walls of the straight rail side plate 104, the transition rail outer side plate 114, the transition rail inner side plate 116, the curved rail outer side plate 108, the curved rail inner side plate 110, the climbing inner rail side plate 120, and the climbing outer rail side plate 124.

[0053] The magnet plate 208 is fixed to the bottom of the vehicle body 201, and the permanent magnet linear motor 209 is fixed on the track 1. The permanent magnet linear motor 209 drives the magnet plate 208 to move along the track 1, thereby driving the sorting trolley to move along the track 1 to complete the delivery and sorting of packages.

[0054] The feeding structure 3 is fixed to the outside of the main track and is used to transport packages to the sorting trolley. The feeding structure 3 includes a flipping component and a feeding component. The flipping component is used to flip the packages to ensure that the label side of the package is facing upwards, which is convenient for subsequent barcode scanning. The feeding component tilts the package with the front facing upwards and transports it onto the sorting trolley to avoid collision between the package and the protective railing.

[0055] like Figure 16-18 As shown, the flipping assembly includes a flipping frame 301, a retaining wheel 302, a retaining groove 303, a flipping plate 304, a gear ring 305, a gear 306, a flipping motor 307, an upper fixing plate 308, an upper guide sleeve 309, an upper guide column 310, an upper clamping plate 311, an upper pressure roller 312, a lower fixing plate 313, a lower guide sleeve 314, a lower guide column 315, a lower clamping plate 316, and a lower pressure roller 317. The flipping frame 301 is fixed to the workshop floor. The retaining wheel 302 is rotatably mounted on the top of the flipping frame 301 via a rotating shaft. The retaining groove 303 is formed on the outer circumferential surface of the retaining wheel 302. The flipping plate 304 is engaged in the retaining groove 303. When the flipping plate 304 rotates, the retaining wheel 302 limits the flipping plate 304, preventing the flipping plate 304 from falling out of the retaining groove 303.

[0056] A gear ring 305 is fixed to one side of the flipping plate 304, and a flipping motor 307 is fixed to the top of the flipping frame 301. A gear 306 is connected to the flipping motor 307 and meshes with the gear ring 305. The flipping motor 307 drives the gear 306 to rotate, which in turn drives the gear ring 305 and the flipping plate 304 to rotate, thus flipping the package and ensuring that the label side of the package faces upwards for easy scanning later.

[0057] The upper fixing plate 308 is fixed between the flipping plates 304, the upper guide sleeve 309 is embedded in the upper fixing plate 308, and the upper guide post 310 passes through the upper guide sleeve 309. By setting the upper guide post 310 and the upper guide sleeve 309 that cooperate with each other, the lifting and lowering movement of the upper clamping plate 311 is guided to improve the accuracy of subsequent clamping.

[0058] The upper clamping plate 311 is fixed to the bottom of the upper guide post 310, the cylinder body of the upper lifting cylinder is fixed to the top of the upper fixed plate 308, the piston rod of the upper lifting cylinder passes through the upper fixed plate 308 and is connected to the upper clamping plate 311, and the upper clamping plate 311 is driven to descend by the upper lifting cylinder, thereby clamping the package.

[0059] The upper pressure roller 312 is rotatably mounted on the bottom of the upper clamping plate 311 via a bearing. After the package is flipped, it is transported to the main conveyor belt 320 by the rotating upper pressure roller 312.

[0060] The lower fixing plate 313 is fixed between the flipping plates 304 and located below the upper fixing plate 308. The lower guide sleeve 314 is embedded in the lower fixing plate 313, and the lower guide post 315 passes through the lower guide sleeve 314. By setting the mutually cooperating lower guide post 315 and lower guide sleeve 314, the lifting and lowering movement of the lower clamping plate 316 is guided to improve the accuracy of subsequent clamping.

[0061] The lower clamping plate 316 is fixed to the top of the lower guide post 315, the cylinder body of the lower lifting cylinder is fixed to the bottom of the lower fixed plate 313, the piston rod of the lower lifting cylinder passes through the lower fixed plate 313 and is connected to the lower clamping plate 316, and the lower clamping plate 316 is driven to rise by the lower lifting cylinder, thereby clamping the package.

[0062] The lower pressure roller 317 is rotatably mounted on the top of the lower clamping plate 316 via a bearing, and the rotating lower pressure roller 317 conveys the package to the main conveyor belt 320.

[0063] During actual package flipping, the upper lifting cylinder lowers the upper clamping plate 311 and upper pressure roller 312, while the lower lifting cylinder raises the lower clamping plate 316 and lower pressure roller 317. The upper and lower pressure rollers 312 and 317 together clamp the package to be flipped, improving clamping stability and preventing the package from falling during flipping. The flipping motor 307 drives the gear 306 to rotate, which in turn drives the gear ring 305 and flipping plate 304 to rotate, completing the flipping of the package and ensuring that the label side of the package faces upwards for easy subsequent barcode scanning. After the package is flipped, the upper clamping plate 311 and lower clamping plate 316 reset, thus conveying the package onto the main conveyor belt 320.

[0064] A CCD camera is fixed to the top of the flip frame 301 to detect whether the package label is facing upwards.

[0065] like Figure 19 As shown, the feeding assembly includes a feeding frame 318, a barcode scanner 319, a main conveyor belt 320, a roller 321, an extension plate 322, a wheel 323, and a secondary conveyor belt 324. The feeding frame 318 is fixed to one side of the tilting frame 301. The feeding roller is rotatably installed between the feeding frames 318. The main conveyor belt 320 is wound around the feeding roller. The motor is fixed to one side of the feeding frame 318 and connected to the feeding roller. The motor drives the feeding roller to rotate, which in turn drives the main conveyor belt 320 to rotate, conveying the face-up packages to the secondary conveyor belt 324.

[0066] The code scanning rack 319 is fixed to the top of the loading rack 318. The code scanning gun is fixed to the bottom of the code scanning rack 319 and faces the main conveyor belt 320, and is used to photograph and scan the packages on the main conveyor belt 320.

[0067] The roller 321 is rotatably installed between the loading racks 318 and is close to the main conveyor belt 320. The extension plate 322 is fixed to the inner side of the loading rack 318, and the lengths of the extension plates 322 are distributed in an arithmetic progression. The rollers 323 are rotatably installed on the side of the extension plate 322 away from the roller 321 through bearings. There are multiple auxiliary conveyor belts 324, which are respectively wound around the roller 321 and the rollers 323, and convey the packages with the front side facing up to the sorting trolley. The roller 321 is a commercially available electric roller.

[0068] Since the lengths of the extension plates 322 are distributed in an arithmetic progression, the side of the auxiliary conveyor belt 324 away from the roller 321 is inclined, as Figure 24 shown. In actual use, the auxiliary conveyor belt 324 is placed close to the sorting trolley of the conveying structure 2. Since the length of the auxiliary conveyor belt 324 is tapered, the auxiliary conveyor belt 324 is inclined on one side of the sorting trolley and forms an acute angle with the sorting trolley.

[0069] After the package is conveyed from the auxiliary conveyor belt 324 to the sorting trolley, the obliquely moving goods F will have a first component motion F1 in the same direction as the moving direction of the sorting trolley and a second component motion F2 perpendicular to the first component motion F1 (it can be known from the decomposition of the force formula that F2 < F). As Figure 23 shown, it is a schematic diagram of the existing conveyor belt structure. After the side conveyor belt perpendicular to the sorting trolley conveys the goods to the sorting trolley, the main motion F has no component motion. Since F2 < F, by reducing the component motion F2 of the goods perpendicular to the sorting trolley, it is possible to prevent the items from colliding with the side wall of the sorting trolley during transportation.

[0070] The blanking structure 4 is fixed to both sides of the track 1 and is used to receive the packages sorted by the sorting trolley. The blanking structure 4 includes a blanking plate 401, a partition block 402, a blanking rack 403, a blanking box 404, a shrapnel assembly and a footrest 410. The blanking plate 401 is obliquely fixed to the top of the gantry. The partition block 402 is fixed to the blanking plate 401. The sorting trolley conveys the package to the blanking plate 401, and the electric roller 202 drives the sorting belt 203 to rotate, and then the package falls into the corresponding blanking box 404 through the blanking plate 401. The partition block 402 can prevent adjacent packages from being mixed.

[0071] As Figure 21 、 22As shown, the stand 410 is fixed to the workshop floor. The top of the stand 410 is folded into a "]" shape. The material dropper 403 is inserted into the "]" shape formed by the top of the stand 410, and the material dropper 403 and the stand 410 are fixed together by bolts and nuts. The stand 410 has a waist-shaped hole, which can adjust the height of the material dropper 403 according to the actual situation.

[0072] like Figure 22 As shown, the spring clip assembly is fixed to the top of the feeding frame 403 to hold the feeding box 404. The spring clip assembly includes a fixing plate 405, an adjusting groove 406, a pressing plate 407, a contact plate 408, and a folding plate 409. The fixing plate 405 has an adjusting groove 406, which is used to fix the fixing plate 405 to the feeding frame 403 by bolts and nuts. The adjusting groove 406 is rounded rectangular and can adjust the distance between the fixing plates 405 to meet the clamping and fixing of feeding boxes 404 of different sizes.

[0073] The extrusion plate 407 is integrally connected to the top of the inner side of the fixing plate 405, and the contact plate 408 is integrally connected to the top of the extrusion plate 407 and is inclined outward. When placing the discharge box 404, the discharge box 404 is clamped between the extrusion plates 407 by pressing the contact plate 408 and the extrusion plate 407 outward. Under the reverse force of the extrusion plate 407, the discharge box 404 is clamped to the top of the discharge frame 403, preventing the discharge box 404 from shifting. Moreover, when replacing, the discharge box 404 can be pulled out without leaving fixing holes on the surface of the discharge box 404, thus avoiding damage to the discharge box 404.

[0074] The flap 409 is integrally connected to the side of the contact piece 408 away from the extrusion piece 407 and is folded outward to contact the contact piece 408, thereby improving the structural strength of the contact piece 408.
