Description

Technical Field

[0001] The invention belongs to the technical field of equipment for packaging materials, and specifically relates to a technology for controlling the volume of filling materials, and in particular to a quantitative filling device and a filling method for spicy sauce. Background Art

[0002] The existing spicy sauce filling process usually uses a screw feeder for feeding, and the speed and filling volume of the filling are controlled by controlling the screw speed and number of revolutions of the screw feeder. However, the spicy sauce is prone to breakpoints when the screw pushes the material, resulting in discontinuous discharge, which affects the accuracy of the filling volume of the sauce, and manual supplementary adjustments are required later. The patent with application number CN200910030284.8 discloses a chili sauce filling valve, which is provided with a roller assembly passing through the groove of the cylinder barrel and fixed on the piston barrel. The roller assembly can move up and down following the motion trajectory of the control cam, thereby causing the piston barrel to move up and down. Piston-type quantitative filling is adopted to ensure the uniformity of the filling volume, reduce the labor intensity of workers and improve production efficiency. However, its overall structure is relatively complex. Summary of the invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides a quantitative filling device and a filling method for spicy sauce, which can effectively ensure the consistency and accuracy of the filling volume, and the filling volume is adjustable and has a simple structure.

[0004] In order to achieve the purpose of the present invention, the following scheme is proposed:

[0005] A quantitative filling device for spicy sauce, comprising:

[0006] The silo has a round tube at the bottom along the vertical direction, a retaining ring is coaxially arranged at the bottom of the round tube, and the inner diameter of the retaining ring is smaller than the inner diameter of the round tube;

[0007] The lifting tube is vertically penetrated at the top of the silo, and a radially arranged positioning hole is opened on the side wall of the lower end of the lifting tube. The lifting tube is movable in the vertical direction, and its lower end is vertically penetrated by a piston; the piston is coaxial with the circular tube, and the outer contour of the piston matches the inner contour of the circular tube; a push rod is radially penetrated by the piston, and the push rod is coaxially arranged with the positioning hole, and a first spring is arranged between the push rod and the outer wall of the lifting tube, for applying pressure toward the outside of the piston to the push rod;

[0008] The adjusting rod is vertically penetrated inside the lifting tube, and a positioning pin is radially penetrated on the side wall of the upper end of the adjusting rod. The adjusting rod is provided with an elastic member for applying pressure toward the outer side of the adjusting rod to the positioning pin; when the piston is located outside the circular tube, the outer end of the push rod protrudes outside the piston, and there is a predetermined distance between the inner end surface of the push rod and the inner wall of the lifting tube, and the outer end of the positioning pin is inserted into the positioning hole; when the piston is coaxially penetrated inside the circular tube, the inner end surface of the push rod is flush with the inner wall of the lifting tube, and the outer end of the positioning pin is separated from the positioning hole;

[0009] The adjusting plate is coaxially arranged in the circular tube. A sealing connection structure is provided between the outer wall of the adjusting plate and the piston and the inner wall of the circular tube. The adjusting plate is arranged at the lower section of the adjusting rod. The distance between the adjusting plate and the piston is less than the length of the circular tube. A discharge pipe is provided at the bottom of the adjusting plate. The inner hole of the discharge pipe passes through the top surface of the adjusting plate. The discharge pipe is provided with an automatic control valve.

[0010] A spicy sauce filling method is implemented by using the above-mentioned spicy sauce quantitative filling equipment, and the spicy sauce filling method comprises the following steps:

[0011] S1: Initial state, the piston is located above the round tube, and the adjustment plate is inserted into the round tube;

[0012] S2: Filling. When the equipment is in the initial state, the spicy sauce in the silo automatically enters the round tube from the gap between the piston and the top of the round tube and is stored above the adjustment plate. During the filling process, the lifting tube is continuously lowered until the bottom surface of the piston is completely in contact with the round tube.

[0013] S3: Discharging, after the bottom surface of the piston contacts the round tube, the lifting tube continues to descend, so that the piston is inserted into the round tube, and then the control valve is opened, and the spicy sauce is discharged from the discharge pipe to start filling, until the spicy sauce in the round tube is completely discharged;

[0014] S4: Restore to the initial state. After filling and discharging are completed, move the lifting pipe upward and close the control valve at the same time until the equipment returns to the initial state.

[0015] The beneficial effects of the present invention are as follows: by forming a cylindrical space of fixed shape between the adjusting plate, the piston and the inner wall of the round tube, and filling the space with spicy pepper sauce, the consistency of the volume of the sauce filled each time can be ensured; the overall structure is simple, and the accuracy of the volume of the sauce filled each time can be ensured, thereby avoiding the subsequent manual filling process and helping to improve production efficiency.

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Embodiment 1, as Figures 1 to 9 As shown, a quantitative filling device for spicy sauce includes: a material bin 1, a lifting pipe 2, an adjusting rod 3 and an adjusting plate 4, etc.

[0029] Specifically, Figure 1 , Figure 4As shown, a circular tube 11 is provided at the bottom of the silo 1 in the vertical direction, and a feeding pipe is provided at the top of the silo 1 for continuously adding spicy sauce into the silo 1, and the silo 1 can be used as a transfer point for the spicy sauce. A retaining ring 12 of a circular ring structure is coaxially provided at the bottom of the circular tube 11, and the inner diameter of the retaining ring 12 is smaller than the inner diameter of the circular tube 11.

[0030] Specifically, Figures 2 to 8 As shown, the lifting tube 2 is vertically penetrated at the top of the silo 1, and the side wall of the lower end of the lifting tube 2 is provided with a radially arranged positioning hole 201. The lifting tube 2 is arranged to move in the vertical direction, and its lower end is vertically penetrated by a piston 21. In a specific scheme, the lifting tube 2 can be coaxially arranged at the lower end of a cylinder or a linear motor movable rod, and the cylinder or linear motor is arranged on the top surface of the silo 1, and the lifting tube 2 is controlled to move in the vertical direction by the cylinder or linear motor. The piston 21 is coaxial with the circular tube 11, and the outer contour of the piston 21 matches the inner contour of the circular tube 11; the piston 21 is radially penetrated with a push rod 22, and the push rod 22 is coaxially arranged with the positioning hole 201. A first spring 23 is arranged between the push rod 22 and the outer wall of the lifting tube 2, which is used to apply pressure toward the outside of the piston 21 to the push rod 22.

[0031] Specifically, Figure 3 , Figure 6 and Figure 8 As shown, a cylindrical hole coaxial with the positioning hole 201 is provided inside the piston 21, and the inner diameter of the cylindrical hole is larger than the outer diameter of the push rod 22. A retaining ring is provided in the middle section of the push rod 22. The first spring 23 is a cylindrical spring, which is arranged in the cylindrical hole. The push rod 22 passes through the first spring 23. The first spring 23 is located between the retaining ring and the outer wall of the lifting tube 2. The first spring 23 is normally in a compressed state, and is used to apply pressure to the push rod 22 toward the outside of the piston 21.

[0032] Specifically, Figures 2 to 8As shown, the adjusting rod 3 is vertically penetrated inside the lifting tube 2, and the upper end side wall of the adjusting rod 3 is radially penetrated with a positioning pin 31, and the positioning pin 31 is arranged to move radially along the adjusting rod 3. The adjusting rod 3 is provided with an elastic member 32, which is used to apply pressure toward the outside of the adjusting rod 3 to the positioning pin 31. When the piston 21 is located outside the circular tube 11, the outer end of the push rod 22 protrudes outside the piston 21, and there is a predetermined distance between the inner end surface of the push rod 22 and the inner wall of the lifting tube 2, and the outer end of the positioning pin 31 is inserted into the positioning hole 201. In this state, the inner end of the push rod 22 can be penetrated in the positioning hole 201, or outside the positioning hole 201, and it can be ensured that there is a predetermined distance between the front end surface of the push rod 22 and the inner wall of the lifting tube 2. Because the push rod 22 is coaxially arranged with the positioning hole 201, no matter what position the inner end of the push rod 22 is in, when the push rod 22 moves toward the inside of the piston 21, the inner end of the push rod 22 can pass through the positioning hole 201. When the piston 21 is coaxially inserted into the circular tube 11, the inner end surface of the push rod 22 is flush with the inner wall of the lifting tube 2, and the outer end of the locating pin 31 is separated from the locating hole 201. This state restriction indicates that when the piston 21 is inserted into the circular tube 11, the push rod 22 is pushed toward the middle of the piston 21 by the inner wall of the circular tube 11, so as to use the push rod 22 to push the locating pin 31 out of the locating hole 201, thereby separating the locating pin 31 from the locating hole 201, and then the adjusting rod 3 can be moved relative to the lifting tube 2 along the axial direction. After the piston 21 is separated from the round tube 11, under the elastic force of the first spring 23, the push rod 22 will automatically move to the outside of the piston 21, so that the outer end of the push rod 22 protrudes out of the outside of the piston 21 again, and a predetermined distance is formed between the inner end surface of the push rod 22 and the inner wall of the lifting tube 2. When the locating pin 31 is aligned with the locating hole 201, under the action of the elastic member 32, the outer end of the locating pin 31 can be automatically inserted into the locating hole 201; as a preferred structure, the elastic member 32 is a cylindrical spring, which is arranged at the rear end of the locating pin 31.

[0033] As a preferred structure, the adjusting rod 3 is a multi-sided structure to prevent the adjusting rod 3 from rotating. Specifically, it can be set to a rectangular rod, a triangular rod or a hexagonal rod, so as to ensure the accuracy of the relative position of the locating pin 31 and the locating hole 201 along the circumference; as another preferred structure, a key and a keyway can be used to prevent the adjusting rod 3 from rotating.

[0034] Specifically, Figure 2 , Figure 4 , Figure 5 , Figure 7 and Fig. 9As shown, the adjusting plate 4 is coaxially penetrated in the circular tube 11, and a sealing connection structure is provided between the outer walls of the adjusting plate 4 and the piston 21 and the inner wall of the circular tube 11. As a conventional sealing structure design, one or more rubber sealing rings can be provided on the outer walls of the adjusting plate 4 and the piston 21 to play a sealing role. The adjusting plate 4 is arranged at the lower section of the adjusting rod 3, and the distance between the adjusting plate 4 and the piston 21 is less than the length of the circular tube 11. A discharge pipe 41 is provided at the bottom of the adjusting plate 4, so that the discharge pipe 41 passes downward from the lower end of the circular tube 11 and from the inside of the retaining ring 12, and the inner hole of the discharge pipe 41 passes through the top surface of the adjusting plate 4, and the discharge pipe 41 is provided with an automatic control valve 42. Specifically, the control valve 42 is a ball valve or a gate valve driven by a motor.

[0035] Preferably, Figure 2 , Figure 4 and Fig. 9 As shown, a limiting ring 411 is provided on the outer wall of the lower end of the discharge pipe 41 . When the top surface of the limiting ring 411 abuts against the bottom surface of the retaining ring 12 , the adjusting plate 4 is still in the circular tube 11 , thereby preventing the adjusting plate 4 from separating from the circular tube 11 .

[0036] Preferably, Figure 2 , Figure 4 As shown, the lifting tube 2 and the adjusting rod 3 are coaxially arranged with the circular tube 11, and the discharge tube 41 is eccentrically arranged on the adjusting plate 4. This structure can ensure the balance of force at various locations on the circumference when the piston 21 and the adjusting plate 4 move, thereby ensuring the coaxial accuracy of the adjusting plate 4 and the piston 21 with the circular tube 11, preventing the adjusting plate 4 and the piston 21 from being skewed, and improving the stability of the adjusting plate 4 and the piston 21 when moving.

[0037] Preferably, Figure 2 , Figure 4 , Figure 5 , Figure 7As shown, a second spring 43 is provided between the top surface of the retaining ring 12 and the bottom surface of the adjusting plate 4. When the second spring 43 is in a natural state, the piston 21 is located above the circular tube 11, and the discharge tube 41 passes through the second spring 43. By providing the second spring 43, after the positioning pin 31 is separated from the positioning hole 201, the elastic force of the second spring 43 can be used to push the adjusting plate 4 to move upward, thereby preventing the adjusting plate 4 from being subjected to excessive gravity and causing the descending speed to be greater than the descending speed of the lifting tube 2, thereby preventing the adjusting rod 3 from falling off from the lower end of the lifting tube 2; on the other hand, after the positioning pin 31 is separated from the positioning hole 201, the adjusting plate 4 can accelerate the reduction of the distance between the adjusting plate 4 and the piston 21 during the ascending process, thereby accelerating the discharge of the spicy sauce in the circular tube 11 and improving the filling speed; and during the discharge After completion, when the lifting tube 2 is moved upward, the second spring 43 can also be used to push the adjustment plate 4 upward to ensure that when the piston 21 is separated from the round tube 11, the adjustment rod 3 is still inserted into the lifting tube 2 to prevent the adjustment rod 3 from being separated from the lifting tube 2. After the piston 21 is separated from the round tube 11, the push rod 22 will automatically move outward to make room for the positioning hole 201 for the positioning pin 31. When the adjusting rod 3 descends until the positioning pin 31 and the positioning hole 201 are coaxial again, the positioning pin 31 can be automatically inserted into the positioning hole 201 to connect the adjusting rod 3 and the lifting tube 2 again.

[0038] Preferably, the adjusting rod 3 vertically passes through the adjusting plate 4, and the adjusting plate 4 is arranged to move along the length direction of the adjusting rod 3, so as to change the distance between the piston 21 and the adjusting plate 4, thereby achieving the purpose of changing the filling volume of the spicy sauce. Figure 2 , Figure 5 , Figure 7 and Fig. 9 As shown, a locking screw 44 is passed through the lower end of the adjusting rod 3, and its front end is pressed against the side wall of the discharge pipe 41 to lock the position of the adjusting plate 4 on the adjusting rod 3. In addition, a screw can be passed through the lower end of the adjusting plate 4 to press the side wall of the adjusting rod 3, which can also achieve the purpose of locking the adjusting plate 4 on the adjusting rod 3.

[0039] Preferably, Figure 2 , Figure 4 , Figure 5 , Figure 7 and Fig. 9 As shown, the control valve 42 includes a valve 421 of a circular structure, which is rotatably arranged inside the discharge pipe 41 through a rotating shaft arranged along the diameter, and a worm gear is coaxially arranged at one end of the rotating shaft of the valve 421. The control valve 42 also includes a driving motor 422 arranged at the bottom of the adjusting plate 4, and the main shaft of the driving motor 422 is provided with a worm meshing with the worm gear. The driving motor 422 drives the valve 421 to rotate through the meshing worm gear and the worm gear, so as to control the opening and closing of the discharge pipe 41.

[0040] Preferably, Figure 2, Figure 4 As shown, the bottom of the silo 1 is an inverted conical structure, and the position where the round tube 11 is connected to the bottom of the silo 1 has an arc chamfer structure to facilitate the smooth movement of the push rod 22 toward the middle of the piston 21 and prevent the push rod 22 from being stuck on the top surface of the round tube 11.

[0041] Preferably, a plurality of groups of positioning pins 31, positioning holes 201 and push rods 22 are arranged along a circumferential array.

[0042] Further preferably, Figure 3 , Figure 6 and Figure 8 As shown, a countersunk hole 301 is coaxially opened at the top of the adjusting rod 3, and the elastic member 32 includes a conical block 321 coaxially arranged in the countersunk hole 301, with its cone top facing upward, the inner end of the positioning pin 31 is in sliding contact with the conical surface of the conical block 321, and a third spring 322 is arranged between the conical block 321 and the bottom surface of the countersunk hole 301, and the third spring 322 generates an upward thrust to the conical block 321. When the positioning pin 31 is inserted into the positioning hole, the inner end of the positioning pin 31 is located in the countersunk hole 301, which is used to prevent the conical block 321 from sliding on the third spring 32 2, the locating pin 31 is disengaged from the counterbore 301, and the third spring 322 is in a compressed state, thereby providing sufficient thrust to the locating pin 31 through the conical block 321. With the above-mentioned structural design, the conical block 321 can be used to apply an outward thrust to multiple locating pins 31 at the same time, so that multiple locating pins 31 are inserted into the corresponding locating holes 201 at the same time; when the locating pin 31 is pushed out of the locating hole 201 by the ejector rod 22, the rear end of the locating pin 31 will push the conical block 321 to move downward, and the third spring 322 is further compressed.

[0043] Embodiment 2, a spicy sauce filling method, is implemented by using the spicy sauce quantitative filling equipment recorded in embodiment 1, and the spicy sauce filling method comprises the following steps:

[0044] S1: initial state, such as Figure 2 , Figure 3 As shown, the piston 21 is located above the circular tube 11, and the adjusting plate 4 is inserted into the circular tube 11; as described in Example 1, at this time, the outer end of the push rod 22 protrudes from the outside of the piston 21, and there is a predetermined distance between the inner end surface of the push rod 22 and the inner wall of the lifting tube 2, and the outer end of the positioning pin 31 is inserted into the positioning hole 201 to keep the relative position between the adjusting rod 3 and the lifting tube 2 fixed, so that the distance between the piston 21 and the adjusting plate 4 is kept fixed, so that the volume of the cylinder surrounded by the inner wall of the circular tube 11, the bottom surface of the piston 21 and the top surface of the adjusting plate 4 can be kept fixed. At this time, the volume occupied by the adjusting rod 3 in the cylinder is removed, and the remaining volume is the volume of the spicy sauce filling.

[0045] S2: filling. When the equipment is in the initial state, the spicy sauce in the silo 1 automatically enters the round tube 11 from the gap between the piston 21 and the top of the round tube 11 and is stored above the adjusting plate 4. During the filling process, the lifting tube 2 is continuously lowered. During the lowering process of the lifting tube 2, the distance between the piston 21 and the top of the round tube 11 will gradually decrease, and the adjusting rod 3 and the adjusting plate 4 will also descend together with the lifting tube 2, thereby increasing the space on the top of the adjusting plate 4, and the spicy sauce will automatically enter the round tube 11 to fill the gradually increasing space. Figure 4 , Figure 5 As shown, until the bottom surface of the piston 21 is completely in contact with the round tube 11, thereby closing the upper end of the round tube 11, under the cover and pressure of the piston 21, the spicy sauce will fill the cylindrical space formed between the adjustment plate 4, the piston 21 and the inner wall of the round tube 11, so as to ensure the consistency of the filling volume of the spicy sauce each time. The space above the control valve 42 of the discharge pipe 41 can be taken into consideration in the filling volume during the design. The control valve 42 is in a closed state during the filling process.

[0046] S3: Discharge, such as Figure 7 , Figure 8 As shown, after the bottom surface of the piston 21 contacts the round tube 11, the lifting tube 2 continues to descend, so that the piston 21 is inserted into the round tube 11, and then the control valve 42 is opened, and the spicy sauce is discharged from the discharge pipe 41 to start the filling work until the spicy sauce in the round tube 11 is completely discharged; in the process of the piston 21 being inserted into the round tube 11, the outer end of the push rod 22 will gradually contact the inner wall of the round tube 11, so that the push rod 22 moves toward the inside of the piston 21, so that the inner end of the push rod 22 pushes the positioning pin 31 toward the middle of the adjusting rod 3, and then the positioning pin 31 is separated from the positioning hole 201; after the positioning pin 31 is separated from the positioning hole 201, due to the outer wall of the adjusting plate 4 There is a sealing structure between the inner wall of the circular tube 11, so there is a certain friction resistance, and the lifting tube 2 continues to descend at the original speed. Due to the existence of resistance, the adjusting plate 4 will slowly descend even under the gravity of itself and the sauce above, but the descending speed of the adjusting plate 4 will also be lower than the descending speed of the lifting tube 2. At this time, the adjusting rod 3 will move upward along the axial direction relative to the lifting tube 2 until the bottom surface of the adjusting plate 4 contacts the retaining ring 12, and the adjusting plate 4 and the adjusting rod 3 will no longer descend. The lifting tube 2 continues to descend, further reducing the distance between the piston 21 and the adjusting plate 4, which is used to promote the rapid discharge of the sauce, thereby increasing the filling speed.

[0047] S4: Restore the initial state. After the filling and discharge are completed, move the lifting tube 2 upward and close the control valve 42 at the same time until the equipment returns to the initial state. In the initial stage of the rise, since the positioning pin 31 and the positioning hole 201 are in a separated state, the lifting tube 2 will rise alone, and the adjusting rod 3 and the adjusting plate 4 will not rise together with the lifting tube 2. Only when the piston 21 is separated from the round tube 11, the top rod 22 will move outward to make room for the positioning pin 31 to connect with the positioning hole 201. When the piston 21 leaves the round tube 11, the adjusting rod 3 may have been separated from the lifting tube 2. In order to avoid the above situation, as a preferred method, the control valve 42 is closed when the lifting tube 2 is moved upward, so that a closed space is formed between the adjusting plate 4 and the piston 21. When the lifting tube 2 rises, if the adjusting plate 4 does not move upward with the lifting tube 2, the air pressure in the confined space will decrease. However, the air pressure in the confined space cannot be reduced indefinitely because the reduced air pressure in the confined space will generate suction on the adjusting plate 4. When the suction on the adjusting plate 4 caused by the reduced air pressure is greater than the resistance to the rise of the adjusting plate 4, the adjusting plate 4 will move upward with the lifting tube 2, and the adjusting rod 3 will also rise together, so that the adjusting rod 3 is always inserted in the lifting tube 2. When the piston 21 is separated from the round tube 11, the closed structure of the enclosed space disappears, and the air pressure will gradually recover. At this time, the adjusting rod 3 will move downward relative to the lifting tube 2. Under the elastic force of the first spring 23, the push rod 22 will automatically move to the outside of the piston 21, so that the outer end of the push rod 22 protrudes out of the outer side of the piston 21 again, and a predetermined distance is formed between the inner end surface of the push rod 22 and the inner wall of the lifting tube 2. When the adjusting rod 3 is lowered until the positioning pin 31 is aligned with the positioning hole 201 again, under the action of the elastic member 32, the outer end of the positioning pin 31 can be automatically inserted into the positioning hole 201, so that the adjusting rod 3 and the lifting tube 2 are connected to form an integral structure again, so that the distance between the adjusting plate 4 and the piston 21 is fixed again; at the same time, when the piston 21 is separated from the round tube 11, the spicy sauce will quickly fill the round tube 11 under the suction of the low pressure in the enclosed space, speeding up the filling speed and the relative movement speed between the adjusting rod 3 and the lifting tube 2, and speeding up the connection between the adjusting rod 3 and the lifting tube 2, so that the device returns to the initial state again.

[0048] The above description is only a preferred embodiment of the present invention, and is not intended to be the only one or to limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
