[0043] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0044] See also Figure 1-Figure 4 As shown, an embodiment of the utility model provides a material collecting device, including a receiving tray 10, a recovery container 20 and a vacuum mechanism 30, wherein the receiving tray 10 is used to receive materials; the recovery container 20 is arranged on at least one side edge of the receiving tray 10, and the recovery container 20 has a accommodating cavity 211 for accommodating materials, and the recovery container 20 is provided with a recovery hole connected to the accommodating cavity 211; the vacuum mechanism 30 is connected to the recovery container 20 to generate negative pressure in the accommodating cavity 211.
[0045] The material dripping from the filling nozzle 61 is received by the receiving tray 10, and a recovery container 20 is arranged at the edge of the receiving tray 10. A negative pressure is generated in the accommodating chamber 211 of the recovery container 20 by the vacuum mechanism 30. Under the action of the negative pressure, the material dripping on the recovery container 20 at the edge of the receiving tray 10 is absorbed through the recovery hole and collected in the accommodating chamber 211, thereby preventing the material from accumulating at the edge of the receiving tray 10, causing the material to drip twice on the container mouth of the filling container 63 and causing the growth of microorganisms at the container mouth.
[0046] See also Figure 1 As shown, in some embodiments, the upper plate surface of the receiving tray 10 is recessed downward to form a cavity 101 on the receiving tray 10. The formed cavity 101 facilitates the collection of materials collected on the receiving tray 10 at the bottom of the tray, thereby facilitating centralized processing of the collected materials. The diameter of the cavity 101 on the receiving tray 10 gradually decreases from top to bottom, so that the receiving tray 10 has an inclined surface to facilitate the flow and collection of materials.
[0047] See also Figure 1 As shown, in some embodiments, the receiving tray 10 has a first end 102 and a second end 103 that are arranged opposite to each other, and the first end 102 and the second end 103 are both provided with a recovery container 20. The recovery container 20 is arranged substantially the same at the first end 102 and the second end 103. The recovery container 20 is arranged at both the first end 102 and the second end 103, so that the material dripping on the edge of the receiving tray 10 can be collected more fully to avoid material accumulation.
[0048] See also Figure 2 As shown, in some embodiments, the recovery container 20 is in the shape of a hollow cylinder, the length direction of the recovery container 20 is parallel to the length direction of the first end 102 or the second end 103 of the receiving tray 10, and the recovery container 20 covers the edge position of the receiving tray 10 at the position of the first end 102 or the second end 103. In some embodiments, a plurality of recovery holes are provided, and the plurality of recovery holes are arranged in a row along the axial direction of the recovery container 20. The central axis of the recovery hole extends along the radial direction of the recovery container 20. Multiple recovery holes are provided in each row. The plurality of recovery holes in the same row are arranged at intervals along the circumferential direction of the recovery container 20. The plurality of rows of recovery holes are evenly arranged along the axial direction of the recovery container 20, and the overall length occupied by the plurality of recovery holes in the same row in the circumferential direction of the recovery container 20 is a part of the circumference of the recovery container 20.
[0049] See also Figure 2-Figure 4In some embodiments, the recycling container includes an outer layer 22 and an inner layer 21, the outer layer 22 is connected to the receiving tray 10, the outer layer 22 is sleeved on the outer peripheral side of the inner layer 21, the shape of the outer layer 22 matches the shape of the inner layer 21, and the recycling holes are set through the outer layer 22 and the inner layer 21. The outer layer 22 and the inner layer 21 can rotate relative to each other so that the recycling holes on the outer layer 22 and the recycling holes on the inner layer 21 are interconnected or staggered. Hereinafter, the recycling holes on the inner layer 21 are referred to as first recycling holes 212, and the recycling holes on the outer layer 22 are referred to as second recycling holes 221. The outer layer 22 and the inner layer 21 are both cylindrical, and the outer layer 22 forms the outer cover structure of the inner layer 21. When it is necessary to receive the material dripping from the filling nozzle 61, the outer layer 22 and the inner layer 21 rotate relative to each other, so that the position of the first recovery hole 212 is connected to the position of the second recovery hole 221, so that the dripping material can enter the accommodating cavity 211 from the second recovery hole 221 and the first recovery hole 212. When it is necessary to clean the docking tray 10, the outer layer 22 and the inner layer 21 rotate relative to each other, so that the position of the first recovery hole 212 is staggered from the position of the second recovery hole 221, and the first recovery hole 212 is partially blocked by the shell wall of the outer layer 22 to prevent the cleaning liquid from entering the accommodating cavity 211.
[0050] See also Figure 2 In some embodiments, the inner wall of the outer layer 22 fits with the outer wall of the inner layer 21 to prevent the gap between the outer layer 22 and the inner layer 21 from being too large to allow materials to enter, causing material accumulation that affects the rotation of the recovery container 20 and makes it difficult to clean.
[0051] In some embodiments, the outer layer 22 and the inner layer 21 are configured to be closed at one end and open at the other end; the open end of the inner layer 21 is inserted into the outer layer 22, which facilitates the assembly of the inner layer 21 in the outer layer 22 and the removal of the inner layer 21 to clean the outer layer 22 separately.
[0052] In some embodiments, the material collection device further includes a rotation drive mechanism 40 connected to the inner layer 21 to drive the inner layer 21 to rotate relative to the outer layer 22. The outer layer 22 is fixedly connected to the receiving tray 10, and the opening of the second recovery hole 221 on the outer layer 22 is set upward, so that when the inner layer 21 is rotated to make the first recovery hole 212 and the second recovery hole 221 face each other, the openings of the first recovery hole 212 and the second recovery hole 221 are both facing upward, which is convenient for receiving dripping materials. The rotation drive mechanism 40 can be a cylinder, which is connected to the inner layer 21 through a transmission structure, as long as it can drive the inner layer 21 to rotate.
[0053] See also Figure 1In some embodiments, the material collecting device further comprises a cleaning pipeline 50, a nozzle 51 and a first drainage pipe 52. The nozzle 51 is arranged on the side of the receiving tray 10. One end of the cleaning pipeline 50 is connected to the nozzle 51, and the other end of the cleaning pipeline 50 is used to connect to the cleaning liquid supply mechanism. The first drainage pipe 52 is connected to the bottom of the receiving tray 10. The cleaning liquid is transported into the cleaning pipeline 50 through the cleaning liquid supply mechanism, and the cleaning liquid is sprayed onto the receiving tray 10 through the nozzle 51 to clean the surface of the receiving tray 10. The cleaning dirty liquid is collected at the bottom of the receiving tray 10 and then discharged through the first drainage pipe 52, so that the automatic cleaning of the receiving tray 10 is realized, and the problem of microbial breeding caused by the long-term accumulation of materials on the receiving tray 10 is avoided, and the problem of frequent manual entry and exit of the filling equipment to replace the receiving tray 10 is avoided, which causes the introduction of external microorganisms and affects the product quality; and the difficulty of cleaning is increased due to the drying and solidification of the materials in the receiving tray 10 due to long-term exposure. The cleaning liquid supplied by the cleaning liquid supply mechanism is disinfectant water, which can be disinfected while cleaning the receiving tray 10. The nozzle 51 is provided at the first end 102 and the second end 103 of the receiving tray 10, and is located on the side of the recovery container 20 close to the center of the receiving tray 10. The nozzle 51 sprays out under the water pressure of the disinfectant water, so that the nozzle 51 will not be blocked by the material.
[0054] See also Figure 1 In some embodiments, the vacuum pumping mechanism 30 includes a vacuum tube 301 connected to a vacuum pump 302 and the recovery container 20, and the vacuum pump 302 provides power to form a negative pressure in the receiving chamber 211 of the recovery container 20. A connector is provided at the end of the recovery container 20, and is connected to the vacuum tube 301 through the connector.
[0055] See also Figure 1 In some embodiments, the material collection device further includes a cleaning branch pipe 53 and a second drain pipe 54, one end of the cleaning branch pipe 53 is connected to the cleaning pipeline 50, the other end of the cleaning branch pipe 53 is connected to the vacuum tube 301, and the second drain pipe 54 is connected to the vacuum tube 301. The cleaning liquid is supplied to the cleaning pipeline 50 through the cleaning liquid supply mechanism, and the cleaning liquid can enter the vacuum tube 301 through the cleaning branch pipe 53 to clean the vacuum tube 301. The dirty liquid in the vacuum tube 301 is discharged through the second drain pipe 54, thereby realizing automatic cleaning of the vacuum tube 301. The cleaning liquid entering the vacuum tube 301 is also disinfectant water, which cleans and disinfects the vacuum tube 301 at the same time. Since the vacuum tube 301 is long and curved, it is not easy to clean manually. By automatically cleaning the vacuum tube 301, the labor intensity can be reduced.
[0056] It should be noted that when the vacuum tube 301 and the receiving tray 10 are cleaned, the first recovery holes 212 of the inner layer 21 and the second recovery holes 221 of the outer layer 22 are in a staggered state.
[0057] It should be pointed out that when recovery containers 20 are provided at both the first end 102 and the second end 103 of the receiving tray 10, each recovery container 20 is provided with a corresponding vacuum tube 301, each vacuum tube 301 is connected to a cleaning branch pipe 53, and the vacuum tubes 301 of each recovery container 20 share a vacuum pump 302.
[0058] In order to facilitate the control of the on-off of the cleaning pipeline 50, the cleaning branch pipe 53, the vacuum tube 301 and other pipelines and avoid the mutual interference of the pipelines, in some embodiments, corresponding valves are provided on each pipeline. Figure 1 , a first valve 501 and a second valve 502 are provided on the cleaning pipeline 50, and a cleaning branch pipe 53 is connected to the cleaning pipeline 50 between the first valve 501 and the second valve 502.

[0059] See also Figure 5 The embodiment of the utility model further provides a filling device, including a filling tray 60, a material collecting device, a feeding mechanism 70 and a discharging mechanism 80. The filling tray 60 is provided with a plurality of filling nozzles 61 in a circumferential direction, and a support seat 62 for placing a filling container 63 is correspondingly provided below some of the filling nozzles 61; the material collecting device is the material collecting device as described above, the material collecting device is provided below another part of the filling nozzles 61, and the receiving tray 10 of the material collecting device spans a plurality of filling nozzles 61 without a support seat 62 along the length direction of the receiving tray 10; the feeding mechanism 70 is used to place the filling container 63 on the support seat 62; the discharging mechanism 80 is used to output the filling container 63.
[0060] During filling, the filling container 63 on the support seat 62 is filled with materials through the filling nozzle 61. When the materials accumulate on the filling nozzle 61, since the filling nozzle 61 and the filling container 63 on the support seat 62 are relatively stationary, the materials accumulated on this part of the filling nozzle 61 can drip into the inside of the filling container 63. For the filling nozzle 61 without the support seat 62 and the filling container 63, in the process of feeding the filling container 63 into the support seat 62 or outputting from the support seat 62, the materials on this part of the filling nozzle 61 have the risk of dripping into the container mouth or the container body of the filling container 63. The receiving tray 10 of the material collection device is placed under this part of the filling nozzle 61, which can be used to collect the materials accumulated on this part of the filling nozzle 61. The materials drip onto the receiving tray 10 and the recovery container 20, and the dripping materials are collected by the receiving tray 10 and the recovery container 20 to avoid secondary dripping of the materials.
[0061] In some embodiments, the filling disk 60 is in the shape of a disk, and the filling disk 60 is driven to rotate by a rotary motor (the arrow in the figure indicates the rotation direction), and the filling disk 60 is connected to the rotary motor through a transmission structure such as a transmission rod 64. The support seat 62 is L-shaped, and the container opening of the filling container on the support seat 62 is opposite to the filling nozzle 61 to receive the material flowing out of the filling nozzle 61.
[0062] See also Figure 5 In some embodiments, the feeding mechanism 70 and the discharging mechanism 80 both adopt a star wheel structure. The feeding mechanism 70 includes an inlet star wheel 701, a first motor and a first transition structure 702. The inlet star wheel 701 is provided with a plurality of slots for transporting the filling container 63 in a circumferential direction. The first transition structure 702 docks the inlet star wheel 701 with one of the support seats 62, and plays the role of docking the slot of the inlet star wheel 701 with the support seat 62; the first motor is connected to the inlet star wheel 701 by transmission, and the inlet star wheel 701 is driven to rotate by the first motor (the arrow in the figure indicates the direction of rotation). The filling container 63 in the slot is delivered to the first transition structure 702 by the rotation of the inlet star wheel 701, and then transported to the support seat 62 through the first transition structure 702. The discharging mechanism 80 includes an outlet star wheel 801, a second motor and a second transition structure 802. The outlet star wheel 801 is provided with a plurality of slots in a circumferential direction. The second transition structure 802 connects the outlet star wheel 801 with one of the support seats 62, and plays the role of docking the slots of the outlet star wheel 801 with the support seat 62. The second motor is connected to the outlet star wheel 801 by transmission, and the outlet star wheel 801 is driven by the second motor to rotate (the arrow in the figure indicates the direction of rotation). The filling container 63 on the support seat 62 is output to the slot of the outlet star wheel 801 through the second transition structure 802, and then the filling container 63 is output by the rotation of the outlet star wheel 801.
[0063] It should be noted that the first transition structure 702 and the second transition structure 802 in the present invention can both adopt a conveyor belt structure, and the operation of the conveyor belt provides power for the transportation of the filling container 63. The import star wheel 701 and the export star wheel 801 both adopt the existing star wheel structure, and the star wheel structure of the import star wheel 701 and the export star wheel 801 for the transportation of the filling container 63 is the existing technology, and the present invention will not be described in detail.
[0064] The working process of the utility model is:
[0065] When collecting materials, the vacuum pump 302 is operated, the third valve member 3011, the fourth valve member 3012 and the fifth valve member 3013 are opened, and the inner layer 21 is driven to rotate by the rotary drive mechanism 40, so that the first recovery hole 212 is opposite to the second recovery hole 221, and the dripping materials are absorbed by the vacuum tube 301.
[0066] After the set time, the pipeline is intermittently flushed. At this time, the first valve 501, the seventh valve 531, the eighth valve 532, and the sixth valve 541 are opened, and the third valve 3011, the fourth valve 3012, the fifth valve 3013, and the second valve 502 are closed, and the disinfectant water flushes and disinfects the vacuum tube 301. The space of the accommodating chamber 211 in the recovery container 20 is larger than that of the vacuum tube 301, and the accumulation of materials will not affect the vacuum suction effect. The accumulation of materials in the accommodating chamber 211 can be solved by periodic manual cleaning.
[0067] This process is repeated to absorb the dripping material.
[0068] When it is necessary to clean the receiving tray 10, the first valve member 501 and the second valve member 502 are opened, and the seventh valve member 531 and the eighth valve member 532 are closed. Disinfectant water is supplied to the nozzle 51 through the cleaning pipeline 50, and the disinfectant water is continuously sprayed out through the nozzle 51 to flush the materials dripping on the receiving tray 10, and is emptied through the first drain pipe 52 to avoid the influence of material accumulation.
[0069] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
