Description

Technical Field

[0001] The present invention belongs to the field of food processing equipment, and particularly relates to a sorting device for fragile materials. Background Art

[0002] During the production process of food cans, manufacturers usually screen and sort the materials before filling to improve the quality of the cans. Generally speaking, the materials to be filled are mainly divided into three types: the first type of material is qualified material, which can be directly filled; the second type of material is unqualified material, which usually has serious damage and cannot be used as the content of the can; the third type of material is the material to be processed, which only has slight damage and can be filled as the can content after secondary processing. Therefore, to save costs and avoid waste, the staff needs to collect the materials to be processed during the sorting process to facilitate their secondary processing.

[0003] In the traditional production process, the sorting and collection of the materials to be processed are usually completed manually by the staff. With the continuous development of automation technology, technicians in this field will choose to use a sorting machine to sort and collect the materials to be processed, thereby improving work efficiency. However, when the materials to be processed are fragile materials (such as orange segments without membranes and grapes without skins), the existing sorting devices will cause damage to the materials, turning the materials to be processed into unqualified materials, thus causing unnecessary economic losses. Summary of the Invention

[0004] In view of this, the present invention aims to provide a sorting device for fragile materials to achieve the purpose of improving the sorting efficiency of fragile materials and avoiding damage to fragile materials during the sorting and collection process.

[0005] To achieve the above object, the technical solution of the present invention is realized as follows:

[0006] A sorting device for fragile materials, comprising: a conveyor mesh belt, a blowing component, and a collection component, wherein the collection component is located above the conveyor mesh belt, and the blowing component is located below the conveyor mesh belt;

[0007] The collection component includes: a collection hood, a collection water tank, and a flow splitter plate. The collection water tank is arranged at the bottom of the collection hood. There is a discharge cut on the bottom surface of the collection hood, and the discharge cut is communicated with the collection water tank. An inlet cut is provided on the side wall of the collection hood close to the conveying mesh belt. The flow splitter plate is arranged inside the inlet cut, and the inlet cut is divided into a medium inlet and a material inlet by the flow splitter plate, and the material inlet is located between the medium inlet and the discharge cut. A reflux cavity and a buffer cavity are arranged inside the collection hood. A medium channel is formed on the side of the flow splitter plate away from the buffer cavity. The reflux cavity is communicated with the medium inlet through the medium channel. The discharge cut and the material inlet are both communicated with the buffer cavity, and the top of the buffer cavity is communicated with the bottom of the reflux cavity.

[0008] The blowing component includes a fairing and an atomizing nozzle. The atomizing nozzle is arranged inside the fairing. A blowing cut is provided on the side wall of the fairing close to the conveying mesh belt, and the blowing cut is aligned with the inlet cut. When sorting fragile materials, the atomizing nozzle can spray water mist through the blowing cut onto the conveying mesh belt. Part of the water mist will contact the materials on the conveying mesh belt, thereby pushing the materials to enter the buffer cavity along the material inlet. Another part of the water mist will enter the reflux cavity along the medium inlet and the medium channel. The reflux cavity can guide the flow direction of the water mist so that this part of the water mist buffers the materials after entering the buffer cavity, thereby reducing or avoiding the collision of the materials with the inner wall of the collection hood and preventing the fragile materials from being damaged during the sorting and collection process. Subsequently, the materials will enter the collection water tank along the discharge cut, and the collection water tank can convey the materials to the downstream processing equipment by means of water flow for secondary processing of the materials.

The connection hole is located between the arc-shaped adjustment hole and the inlet cut, and the connection hole coincides with the center of the arc of the arc-shaped adjustment hole. A connection shaft and an adjustment shaft are provided on the side wall of the flow splitter plate. The connection shaft is rotatably placed inside the connection hole, and the adjustment shaft is placed inside the arc-shaped adjustment hole.

[0011] Further, the collection hood includes a hood shell body and a top plate. A cleaning cut is provided at the top of the hood shell body. The discharge cut and the inlet cut are both located on the hood shell body. The top plate is placed inside the cleaning cut, and one end of the top plate is hinged to the inner side wall of the cleaning cut away from the inlet cut.

[0012] Further, the top plate includes a guiding section, an arc-shaped diversion section, an arc-shaped return section, and a connecting section that are sequentially connected; the inner wall of the guiding section is tangent to the inner wall of the arc-shaped diversion section, and the medium channel is formed between the guiding section and the splitter plate; the arc centers of the arc-shaped diversion section and the arc-shaped return section both face the return cavity, and the inner wall of the arc-shaped return section is tangent to the inner wall of the arc-shaped diversion section; the inner wall of the connecting section is tangent to the inner wall of the arc-shaped return section, and the connecting section is connected to the inner side wall of the cleaning incision far from the feeding incision through a hinge.

[0013] Further, the blowing assembly further includes a baffle plate, which is arranged inside the blowing incision. The blowing incision is divided into a first outlet and a second outlet by the baffle plate, and the first outlet is directly opposite to the medium inlet, and the second outlet is directly opposite to the material inlet.

[0014] Further, a first long circular hole and a second long circular hole are provided on the side wall of the fairing. The length directions of the first long circular hole and the second long circular hole are both perpendicular to the length direction of the baffle plate, and the first long circular hole is located between the second long circular hole and the conveying mesh belt; a first connecting rod and a second connecting rod are provided on the side wall of the baffle plate, and the first connecting rod is placed inside the first long circular hole, and the second connecting rod is placed inside the second long circular hole.

[0015] Further, both the collection assembly and the blowing assembly are multiple. The multiple collection assemblies are evenly arranged along the width direction of the conveying mesh belt. The multiple blowing assemblies are arranged in one-to-one correspondence with the multiple collection assemblies, and the collection water tanks of any two adjacent conveying assemblies are communicated with each other.

[0016] Further, support frames are provided on both sides of the conveying mesh belt. The outer side wall of the collection water tank is attached to the top surface of the support frame, and a conveying gap allowing qualified materials to pass through is formed between the top surface of the support frame and the top surface of the conveying mesh belt.

[0017] Further, the conveying mesh belt includes a sorting section and an identification section. The length direction of the identification section is parallel to the horizontal plane. An image acquisition device for acquiring material images is provided above the identification section; the length direction of the sorting section forms an angle of 30° to 60° with the horizontal plane. One end of the sorting section close to the identification section is higher than the end far from the identification section, and the collection assembly and the blowing assembly are respectively located on the upper and lower sides of the sorting section.

[0018] Compared with the prior art, the fragile material sorting device of the present invention has the following advantages:

[0019] (1) A fragile material sorting device according to the present invention can sort and collect materials through the cooperation of a blowing component and a collecting component. Compared with the traditional manual sorting method, this device can improve the collection speed of materials, thereby improving the working efficiency of sorting. In addition, the device is provided with a reflux cavity, a buffer cavity, and a medium channel inside the collection hood, and a medium inlet and a material inlet are provided on the side wall of the collection hood. When performing sorting and collection work, a part of the water mist generated by the blowing component can cause the materials to enter the buffer cavity along the material inlet, and another part of the water mist will enter the buffer cavity in the order of medium inlet - medium channel - reflux cavity, thereby buffering the materials to prevent the materials from colliding with the inner wall of the collection hood, and further avoiding damage to the fragile materials during the automated sorting and collection process.

[0020] (2) A fragile material sorting device according to the present invention is provided with a separation arc surface, an arc-shaped protrusion, and a guiding slope on the diversion plate. By setting the separation arc surface, the separation difficulty between the water mist and the diversion plate can be reduced, facilitating the water mist to enter the reflux cavity. By setting the guiding slope and the arc-shaped protrusion, the inner diameter of the medium channel can be gradually reduced, thereby increasing the flow rate of the water mist when it enters the reflux cavity and ensuring that the water mist buffers the materials before the materials collide with the inner wall of the collection hood.

[0021] (3) The top plate of a fragile material sorting device according to the present invention includes a guiding section, an arc-shaped guiding section, an arc-shaped reflux section, and a connecting section connected in sequence. Since the centers of the arcs of the arc-shaped guiding section and the arc-shaped reflux section both face the reflux cavity, the flow direction of the water mist can be guided through the cooperation of the arc-shaped guiding section and the arc-shaped reflux section to ensure that the water mist enters the buffer cavity. In addition, since the inner walls of the guiding section, the arc-shaped guiding section, the arc-shaped reflux section, and the connecting section are tangent in sequence, the resistance of the water mist during the flowing process can be reduced, ensuring that the water mist has sufficient material buffering effect.

[0034] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0035] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0036] A sorting device for fragile materials, the structure of which can be schematically shown by Figures 1-7 As shown in the figure, in this embodiment, the sorting device for fragile materials includes: a conveyor mesh belt, a blowing assembly, and a collection assembly. When in use, the conveyor mesh belt is used to convey materials, the blowing assembly is used to blow the materials to be sorted and collected off the conveyor mesh belt, and the collection assembly is used to recover the materials blown off the conveyor mesh belt for subsequent equipment to perform secondary processing on the materials.

[0037] It should be noted that in order to facilitate the contact between the blowing medium generated by the blowing assembly and the materials on the conveyor mesh belt, the conveyor mesh belt described in this embodiment can be selected as the common type B mesh belt in the prior art, so as to facilitate the flow of the blowing medium along the pores of the type B mesh belt.

[0038] Specifically, in this embodiment, the collection assembly should be located above the conveyor mesh belt, and the blowing assembly should be located below the conveyor mesh belt. As Figure 3 shown, the collection assembly includes a collection hood and a collection water tank 3, wherein the collection water tank 3 is arranged at the bottom of the collection hood, a feed cut is provided on the side wall of the collection hood close to the conveyor mesh belt, and a discharge cut 211 communicating with the collection water tank 3 is provided on the bottom surface of the collection hood. As Figure 6 shown, the blowing assembly includes a rectifying hood 5 and an atomizing nozzle 6, wherein the atomizing nozzle 6 is arranged inside the rectifying hood 5, and a blowing cut opposite to the feed cut is provided on the side wall of the rectifying hood 5 close to the conveyor mesh belt.

[0039] When carrying out the material sorting and collection work, the atomizing nozzle 6 can spray water mist through the blowing cut towards the conveying mesh belt. Since the collection component and the blowing component are respectively located on the upper and lower sides of the conveying mesh belt, when the water mist contacts the materials on the conveying mesh belt, the materials will move towards the collection component under the push of the water mist. In addition, since the blowing cut on the fairing 5 is aligned with the feeding cut on the collection hood, the pushed materials will enter the interior of the collection hood along the feeding cut and finally leave the collection hood along the discharging cut 211 and enter the collection water tank 3. The staff can introduce flowing water into the interior of the collection water tank 3, so as to convey the materials to the subsequent equipment for secondary processing by means of the water flow, thereby improving the utilization rate of the materials.

[0040] It should be noted that when there are both qualified materials and materials to be processed on the conveying mesh belt, the staff should adjust the water mist spraying timing and the water mist spraying duration of the atomizing nozzle 6 according to the material conveying speed of the conveying mesh belt, so that the atomizing nozzle 6 only sprays water mist when the materials to be processed pass through the area where the blowing cut is located, thereby avoiding the qualified materials from entering the interior of the collection component. Correspondingly, in order to prevent the collection component from blocking the qualified materials on the conveying mesh belt, as Figure 2 shown, support frames 13 can be provided on both sides of the conveying mesh belt in this embodiment. During assembly, the outer side wall of the collection water tank 3 should be fitted with the top surface of the support frame 13, and a conveying gap allowing the qualified materials to pass through should be formed between the top surface of the support frame 13 and the top surface of the conveying mesh belt, so that the qualified materials can be transported to the interior of the subsequent filling equipment through the conveying mesh belt.

[0041] During the actual working process, the materials to be sorted and collected may be orange segments with the saccharine removed or grapes with the peel removed, etc., which are fragile materials. When carrying out automatic sorting for such materials, the materials are very likely to be damaged due to collision during the sorting process, thus causing unnecessary waste. To solve this problem, this embodiment will utilize the water mist that does not contact the materials through the collection component, thereby using this part of the water mist to buffer the materials and avoid the materials from being damaged by collision during the sorting and collection process.

[0042] Specifically, as Figure 3 shown, the collection component further includes a flow dividing plate 4. During assembly, the flow dividing plate 4 should be arranged inside the feeding cut. The feeding cut can be divided into a medium inlet 212 and a material inlet 213 through the flow dividing plate 4, and the material inlet 213 is located between the medium inlet 212 and the discharging cut 211. At the same time, a reflux cavity 214 and a buffer cavity 215 are provided inside the collection hood, and a medium channel 216 is formed on the side of the flow dividing plate 4 away from the buffer cavity 215. Among them, the reflux cavity 214 is connected to the medium inlet 212 through the medium channel 216, both the discharging cut 211 and the material inlet 213 are connected to the buffer cavity 215, and the top of the buffer cavity 215 is connected to the bottom of the reflux cavity 214.

[0043] When the fragile materials on the conveyor belt pass through the area where the blowing cut is located, the atomizing nozzle 6 will spray water mist through the blowing cut onto the conveyor belt. At this time, a part of the water mist will come into contact with the fragile materials, thereby pushing the fragile materials into the buffer cavity 215 along the material inlet 213. Since the water mist ejected by the atomizing nozzle 6 includes compressed air and a large number of fine droplets evenly dispersed in the compressed air, compared with the traditional material sorting method that uses high-pressure air flow as the blowing medium, the blowing medium selected in this embodiment exerts a softer force on the fragile materials under the premise of achieving the same pushing effect, so it can reduce the damage caused by the blowing medium to the materials. At the same time, the fine droplets dispersed in the compressed air can also clean the inner wall of the collection hood, so that the inside of the collection assembly remains clean during continuous operation.

[0044] Normally, since the water mist spraying area of the atomizing nozzle 6 is inversely proportional to the spraying pressure, when blowing the fragile materials, the staff will reduce the impact pressure borne by the fragile materials by increasing the water mist spraying area of the atomizing nozzle 6. In this way, the water mist spraying area of the atomizing nozzle 6 will be larger than the cross-sectional area of the fragile materials, and the water mist that does not come into contact with the fragile materials will enter the reflux cavity 214 through the medium inlet 212 and the medium channel 216. Since the top of the buffer cavity 215 is connected to the bottom of the reflux cavity 214, the flow direction of this part of the water mist will change inside the reflux cavity 214. When the water mist inside the reflux cavity 214 enters the buffer cavity 215, this part of the water mist will buffer and block the fragile materials entering the buffer cavity 215, thereby preventing the fragile materials from colliding with the inner wall of the collection hood and further preventing the fragile materials from being damaged during the sorting and collection process.

[0045] Optionally, for the convenience of the staff to conduct a thorough cleaning after the long-term use of this device, as Figure 4 shown, the collection hood may include a hood body 21 and a top plate. The top of the hood body 21 should be provided with a cleaning cut, and the discharge cut 211 and the feed cut are both located on the hood body 21. The top plate should be placed inside the cleaning cut, and one end of the top plate should be hinged to the inner wall of the cleaning cut away from the feed cut. When a thorough cleaning of the collection assembly is required, the staff can drive the top plate to flip around the hinge point, so that the cleaning cut is opened to ensure the smooth progress of the cleaning work.

[0046] In addition, to improve the guiding effect of the return cavity 214 on the flow direction of the water mist, in this embodiment, the top plate may include a guiding section 221, an arc-shaped diversion section 222, an arc-shaped return section 223, and a connecting section 224 that are sequentially connected. During assembly, the connecting section 224 will be connected to the inner wall of the cleaning incision far from the feeding incision through a hinge 225. After the top plate enters the cleaning incision, the centers of the arcs of the arc-shaped diversion section 222 and the arc-shaped return section 223 both face the return cavity 214, and the medium channel 216 is formed between the guiding section 221 and the diversion plate 4. When the water mist enters the return cavity 214 along the medium channel 216, the arc-shaped structures of the arc-shaped diversion section 222 and the arc-shaped return section 223 can guide the flow direction of the water mist to change, so that the water mist in the return cavity 214 blocks and buffers the movement of the fragile material after entering the buffer cavity 215. In addition, to reduce the resistance of the water mist during the flowing process, the inner wall of the guiding section 221 should be tangent to the inner wall of the arc-shaped diversion section 222, the inner wall of the arc-shaped return section 223 should be tangent to the inner wall of the arc-shaped diversion section 222, and the inner wall of the connecting section 224 should be tangent to the inner wall of the arc-shaped return section 223. When the inner walls of the guiding section 221, the arc-shaped diversion section 222, the arc-shaped return section 223, and the connecting section 224 are tangent in sequence, the energy loss of the water mist during the flowing process can be significantly reduced, so as to ensure that the water mist has sufficient buffering effect on the fragile material.

[0047] It should be noted that in this embodiment, the length direction of the guiding section 221 should be parallel to the axis direction of the atomizing nozzle 6 to prevent the guiding section 221 from blocking the water mist from entering the medium channel 216. At the same time, the length direction of the connecting section 224 should form an angle of 30° to 60° with the vertical direction, so as to ensure that the water mist has a good buffering effect on the fragile material after entering the buffer cavity 215.

[0048] Optionally, to ensure that the water mist inside the return cavity 214 contacts the fragile material before the fragile material collides, in this embodiment, an arc-shaped protrusion 41, a guiding slope 42, and a separating arc surface 43 may be provided on the diversion plate 4. As Figure 3 and Figure 5As shown in the figure, the arc-shaped protrusion 41 is arranged on the side wall of the flow dividing plate 4 close to the medium channel 216. The guiding slope 42 is arranged on the side of the arc-shaped protrusion 41 close to the medium inlet 212, and the separation arc surface 43 is arranged on the side of the arc-shaped protrusion 41 close to the return cavity 214. Both the separation arc surface 43 and the guiding slope 42 are tangent to the outer side wall of the arc-shaped protrusion 41. By arranging the guiding slope 42 and the arc-shaped protrusion 41, the inner diameter of the medium channel 216 can be gradually reduced along the direction from the medium inlet 212 to the return cavity 214. On the premise that the water mist flow rate remains unchanged, the reduction of the inner diameter of the medium channel 216 can increase the water mist flow velocity, so that the water mist can quickly enter the interior of the return cavity 214, and then flow into the buffer cavity 215 before the fragile material collides. By arranging the separation arc surface 43, the separation difficulty between the water mist and the flow dividing plate 4 can be reduced, thereby reducing the along-way loss of the water mist and ensuring that there is enough water mist flow rate during the buffering work of the fragile material.

[0049] Since different materials have different moving speeds during the sorting and blowing process, to improve the adaptability of the device, connection holes 217 and arc-shaped adjustment holes 218 can be provided on the side wall of the collection hood. The connection hole 217 should be located between the arc-shaped adjustment hole 218 and the feeding cut, and the arc centers of the connection hole 217 and the arc-shaped adjustment hole 218 coincide. Correspondingly, a connection shaft 44 and an adjustment shaft 45 should be provided on the side wall of the flow dividing plate 4. During assembly, the staff can rotatably place the connection shaft 44 inside the connection hole 217 and place the adjustment shaft 45 inside the arc-shaped adjustment hole 218. Before use, the staff can drive the flow dividing plate 4 to rotate around the connection shaft 44 to adjust the internal size of the medium channel 216, and then fix the position of the adjustment shaft 45 inside the arc-shaped adjustment hole 218 through a nut to prevent abnormal movement of the flow dividing plate 4 during use.

[0050] Figure 7 As an explosion diagram of the blowing component, to facilitate controlling the water mist entry amount of the medium inlet 212 and the material inlet 213, the blowing component described in this embodiment may further include a diversion plate 7. Specifically, the diversion plate 7 should be arranged inside the blowing cut. The blowing cut can be divided into a first outlet 51 and a second outlet 52 through the diversion plate 7. The first outlet 51 is directly opposite to the medium inlet 212, and the second outlet 52 is directly opposite to the material inlet 213. The staff can adjust the cross-sectional areas of the first outlet 51 and the second outlet 52 by adjusting the position of the diversion plate 7, thereby controlling the water mist entry amount of the medium inlet 212 and the material inlet 213.

[0051] Optionally, for the convenience of adjusting the position of the deflector 7, a first oblong hole 53 and a second oblong hole 54 may be provided on the side wall of the fairing 5. The length directions of the first oblong hole 53 and the second oblong hole 54 should be perpendicular to the length direction of the deflector 7, and the first oblong hole 53 is located between the second oblong hole 54 and the conveying mesh belt. Correspondingly, a first connecting rod 71 and a second connecting rod 72 should be provided on the side wall of the deflector 7. During installation, the first connecting rod 71 should be placed inside the first oblong hole 53, and the second connecting rod 72 should be placed inside the second oblong hole 54. When it is necessary to adjust the position of the deflector 7, the staff can drive the first connecting rod 71 to slide inside the first oblong hole 53 and drive the second connecting rod 72 to slide inside the second oblong hole 54, so that the position of the deflector 7 matches the actual requirements. After the adjustment is completed, the staff can fix the positions of the first connecting rod 71 and the second connecting rod 72 through nuts to prevent the deflector 7 from moving abnormally during operation.

[0052] As an alternative implementation of this embodiment, to improve the automation degree of the device, as Figure 1 and Figure 2 shown, the conveying mesh belt may include a sorting section 11 and an identification section 12. The length direction of the identification section 12 should be parallel to the horizontal plane, the length direction of the sorting section 11 should form an angle of 30° to 60° with the horizontal plane, and the end of the sorting section 11 close to the identification section 12 should be higher than the end far from the identification section 12. The staff can set an image acquisition device 8 above the identification section 12 through a bracket (not shown in the figure), and respectively set the collection assembly and the blowing assembly on the upper and lower sides of the sorting section 11. During operation, the material image on the identification section 12 can be obtained through the image acquisition device 8, and then it is judged whether the current material needs to be sorted and collected according to the material image. When the material needs to be sorted and collected, after the material moves to the area where the blowing cut is located, the atomizing nozzle 6 can be driven to spray water mist through a control unit (not shown in the figure, a common industrial control system can be selected), thereby completing the sorting and collection work of the material.

[0053] As another alternative implementation of this embodiment, to increase the processing capacity of the device, both the collection assembly and the blowing assembly can be set to be multiple. During assembly, multiple collection assemblies should be evenly arranged along the width direction of the conveying mesh belt, multiple blowing assemblies should be arranged in one-to-one correspondence with the multiple collection assemblies, and the collection water tanks 3 of any two adjacent conveying assemblies are connected. In the above state, the staff can adjust the number of materials on the conveying mesh belt according to the number of collection assemblies and arrange multiple materials in the width direction on the conveying mesh belt. At this time, the device will be able to process multiple materials synchronously, thus meeting the actual processing requirements.

[0054] The effects of the above solutions will be described below:

[0055] This embodiment provides a sorting device for fragile materials, which can quickly sort and collect fragile materials through the cooperation of a collection component and a blowing component. At the same time, through the cooperation of a reflux cavity, a buffer cavity, a medium channel and a shunt plate, water mist can be used to buffer the materials, avoiding collision damage to the fragile materials during the collection process. In addition, the position of the shunt plate and the diversion plate of this device can be adjusted according to actual needs, so as to meet different working requirements.

[0056] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
