Description

Technical Field

[0001] The present invention belongs to the technical field of hot pot base production, and particularly relates to a packing process for spicy hot pot base. Background Art

[0002] After the spicy hot pot base is stir-fried, it needs to be filled into a material box after a series of processes, and then compacted, frozen and formed before being sealed. Existing material boxes include, for example, the packaging box disclosed in CN306260633S; the hot pot base packaging box disclosed in CN306017508S; the hot pot base packaging box disclosed in CN211767609U, which includes a box body and a cover film. The box body includes a left box body and a right box body, and the left box body and the right box body are connected by a telescopic bending section. The left box body, the right box body and the telescopic bending section jointly enclose a receiving cavity for accommodating the hot pot base, and the receiving cavity has a regular geometric shape.

[0003] Currently, it is mainly to manually hold the material box to quantitatively receive the spicy hot pot base at the filling gun nozzle of the filling equipment, and then the operator manually transfers the filled material box to the compaction station, and uses a pressing plate (a flat plate with a handle) to compact the spicy hot pot base in the material box, and then transfers it to the freezer for freezing and forming. However, the problems with this method are: the packing efficiency of the spicy hot pot base is low, and each set of filling equipment requires four operators (for receiving materials, first transfer, compaction, and second transfer respectively), and the per capita filling volume is only 6 - 8 boxes per minute; the oil is likely to spill, and there will be a lot of oil on the operation area and the ground; the operation process is cumbersome, especially the compaction process is very likely to cause the operator's arm to ache. Summary of the Invention

[0004] Aiming at the problems in the background art, the purpose of the present invention is to provide a packing process for spicy hot pot base with high packing efficiency, not easy to spill oil and simple process steps.

[0005] To achieve the foregoing purpose, the present invention adopts the following technical solutions.

[0006] A packing process for spicy hot pot base, characterized in that:

[0007] A rotary loading system is used for receiving materials and transferring the material box. The rotary loading system includes a disc connected to the output end of a motor. Four evenly arranged rectangular notches are provided on the disc in the circumferential direction. The rectangular notches are used for clamping the material box. A filling gun of the filling equipment is provided above the edge of the disc, and a conveyor belt is provided on the opposite side of the filling gun. The top surface of the left end of the conveyor belt is located below the edge of the disc. During the rotation of the disc, all the rectangular notches can be successively located directly below the filling gun and directly above the left end of the conveyor belt;

[0008] The steps of the packing process include:

[0009] Step 1: Place the empty material box into the vacant first rectangular notch at the box loading station, so that the empty material box is stuck in the first rectangular notch.

[0010] Step 2: Control the disc to rotate clockwise by 90°, so that the empty material box is located directly below the filling gun, and then pour an appropriate amount of spicy hot pot base into the empty material box; at the same time, place an empty material box in the second rectangular notch.

[0011] Step 3: After Step 2 ends, control the disc to continue rotating clockwise by 90°. At this time, pour an appropriate amount of spicy hot pot base into the empty material box in the second rectangular notch, and at the same time, place an empty material box in the third rectangular notch.

[0012] Step 4: After Step 3 ends, control the disc to continue rotating clockwise by 90°. At this time, pour an appropriate amount of spicy hot pot base into the empty material box in the third rectangular notch, and at the same time, place an empty material box in the fourth rectangular notch; at the same time, remove the material box-containing box in the first rectangular notch.

[0013] Step 5: Repeat the above Steps 1 to 4.

[0014] To further improve the box loading efficiency and avoid oil spillage at the same time, a plate body is provided above the left end of the conveyor belt. The vertical plate of the plate body is located inside the fourth rectangular notch and leans towards the side of the filling gun. The top of the plate body is connected to a horizontal cylinder. When the horizontal cylinder retracts, the material box-containing box is scraped onto the conveyor belt by means of the plate body.

[0015] Further, the vertical distance between the top surface of the conveyor belt and the bottom surface of the material box-containing box at the fourth rectangular notch is 3 - 5 mm; the box loading process further includes Step 6: Place the removed material box-containing box stably, and use a pressing member located directly above the material box-containing box to press the spicy hot pot base inside the material box-containing box. After compaction, transfer the material box-containing box to the freezer.

[0016] To better avoid oil spillage, the pressing member is a cone, the bottom surface of the cone is also a conical surface, and the lowest point of the bottom surface of the cone is located on the axial direction of the pressing member. The height difference between the lowest point of the bottom surface of the cone and the edge of the pressing member is not more than 3 mm.

[0017] Preferably, the pressing member is driven by a vertical cylinder arranged vertically.

[0018] To further improve the box loading efficiency, the rotary loading system further includes a controller. The controller is respectively connected to and controls the motor, the horizontal cylinder, the vertical cylinder, and the power system of the conveyor belt. When the processor of the controller executes its program, the following steps are realized:

[0019] Step A: Control the motor to rotate at a preset frequency and a preset speed, so that the disc rotates clockwise by 90° each time and then control the motor to pause for 2 - 3 seconds. When the motor pauses, control the filling equipment to fill the empty material box directly below the filling gun.

[0020] Step B, when the material-containing box filled with spicy hot pot base is located directly outside the plate body, first control the telescopic rod of the horizontal cylinder to retract, scrape the material-containing box onto the conveyor belt, and then control the telescopic rod of the horizontal cylinder to quickly reset during each 90° clockwise rotation of the disc (this can avoid interference between the plate body and the material box).

[0021] Step C, when the material-containing box on the conveyor belt moves to directly below the pressing member as the conveyor belt moves, first control the power system of the conveyor belt to stop for 1 - 2 seconds, and then control the pressing member to move downward by a preset amount instantaneously and then quickly reset.

[0022] To further improve the box loading efficiency, a cone is provided above the end of the conveyor belt. The cone is arranged vertically and is directly above the fourth rectangular notch. The top of the cone is connected to a second vertical cylinder, and the second vertical cylinder is connected to the horizontal cylinder. When the second vertical cylinder drives the cone to move downward to a preset position, the side wall of the lower part of the cone just contacts the inner wall of the material-containing box; when the horizontal cylinder retracts, the material-containing box is scraped onto the conveyor belt by means of the cone.

[0023] Furthermore, the rotary loading system further includes a controller, which is respectively connected to and controls the motor, the horizontal cylinder, the second vertical cylinder, and the power system of the conveyor belt. When the processor of the controller executes its program, the following steps are realized:

[0024] Step S1, control the motor to rotate at a preset frequency and a preset speed, so that after each 90° clockwise rotation of the disc, control the motor to pause for 2 - 3 seconds. When the motor pauses, control the filling equipment to fill the empty material box directly below the filling gun.

[0025] Step S2, when the material-containing box filled with spicy hot pot base is directly below the cone, first control the telescopic rod of the second vertical cylinder to extend downward by a preset amount, then control the telescopic rod of the horizontal cylinder to retract, bring the material-containing box onto the conveyor belt, then control the telescopic rod of the second vertical cylinder to quickly reset during each 90° clockwise rotation of the disc, and finally control the telescopic rod of the horizontal cylinder to reset.

[0026] The solution provided by the present invention can greatly improve the efficiency of loading the spicy hot pot base into boxes. Each set of filling equipment only needs to be equipped with one operator, and the filling quantity can be increased to 25 - 45 boxes per minute. Compared with the existing method, the filling cost can be reduced by about 60%; by adopting the solution provided by the present invention, the amount of oil spillage is very small, and the operation process is simple, completely avoiding the problem that the compaction process easily causes soreness in the operator's arm. In addition, in one of the solutions of the present invention, the compaction process and the process of transferring the material box are skillfully integrated together, further simplifying the operation process.

[0030] The present invention will be further described below.

[0031] Embodiment 1

[0032] First, the rotary loading system used in this embodiment will be described.

[0033] As shown in Figure 1 、 Figure 3 , the rotary loading system includes a disc 3 connected to the output end of a motor 2. Four uniformly arranged rectangular notches are provided on the disc 3 in the circumferential direction. The first rectangular notch 41 at the 0° (360°) position on the circumference, the second rectangular notch 42 at the 90° position, the third rectangular notch 43 at the 180° position, and the fourth rectangular notch 44 at the 270° position. The rectangular notches are used to hold the material boxes 1. A filling gun 6 of a filling device is arranged above the edge of the disc 3 (the filling device is a prior art and will not be elaborated). A conveyor belt 7 is arranged on the opposite side of the filling gun 6. The top surface of the left end of the conveyor belt 7 is located below the edge of the disc 3. During the rotation of the disc 3, all the rectangular notches can be successively located directly below the filling gun 6 and directly above the left end of the conveyor belt 7.

[0034] Among them, a plate body 10 is arranged above the left end of the conveyor belt 7. The vertical plate of the plate body 10 is located inside the fourth rectangular notch 44 and leans towards the filling gun 6. The top of the plate body 10 is connected to a horizontal cylinder 11. When the horizontal cylinder 11 retracts, the material box 8 containing materials is scraped onto the conveyor belt 7 by means of the plate body 10. The vertical distance between the top surface of the conveyor belt 7 and the bottom surface of the material box 8 at the fourth rectangular notch 44 is 3 - 5 mm. The pressing member 9 is a cone (made of polytetrafluoroethylene). The bottom surface of the cone is also a conical surface, and the lowest point of the bottom surface of the cone is located on the axial direction of the pressing member 9. The height difference between the lowest point of the bottom surface of the cone and the edge of the pressing member 9 is 2 mm. The pressing member 9 is driven by a vertical cylinder 12 arranged vertically.

[0035] A process for boxing a spicy hot pot base material uses the rotary loading system in this embodiment to receive and transfer the material boxes. The steps include:

[0036] Step 1, place an empty material box 1 into the vacant first rectangular notch 41 at the boxing station, and make the empty material box 1 stuck in the first rectangular notch 4;

[0037] Step 2: Control the disc 3 to rotate clockwise by 90°, so that the empty material box 1 is located directly below the filling gun 6, and then pour an appropriate amount of spicy hot pot base into the empty material box 1; at the same time, place the empty material box 1 in the second rectangular notch 42.

[0038] Step 3: After Step 2 is completed, control the disc 3 to continue rotating clockwise by 90°. At this time, pour an appropriate amount of spicy hot pot base into the empty material box 1 in the second rectangular notch 42, and at the same time, place the empty material box 1 in the third rectangular notch 43.

[0039] Step 4: After Step 3 is completed, control the disc 3 to continue rotating clockwise by 90°. At this time, pour an appropriate amount of spicy hot pot base into the empty material box 1 in the third rectangular notch 43, and at the same time, place the empty material box 1 in the fourth rectangular notch 44; at the same time, remove the material-containing box 8 in the first rectangular notch 41.

[0040] Step 5: Repeat the aforementioned Steps 1 to 4.

[0041] Step 6: Place the removed material-containing box 8 stably on the conveyor belt 7, and use the pressing member 9 located directly above the material-containing box 8 to press the spicy hot pot base in the material-containing box 8. After compaction, transfer the material-containing box 8 to the freezer.

[0042] Furthermore, use a controller to achieve intelligent control of the process steps. The rotary loading system also includes a controller, which is respectively connected to and controls the motor 2, the horizontal cylinder 11, the vertical cylinder 12, and the power system of the conveyor belt 7. When the processor of the controller executes its program, the following steps are achieved:

[0043] Step A: Control the motor 2 to rotate at a preset frequency and preset speed, so that the disc 3 rotates clockwise by 90° each time, and then control the motor 2 to pause for 3 seconds. When the motor 2 pauses, control the filling device to fill the empty material box 1 directly below the filling gun 6 with material.

[0044] Step B: When the material-containing box 8 filled with spicy hot pot base is located directly outside the plate body 10, first control the telescopic rod of the horizontal cylinder 11 to retract, scrape the material-containing box 8 onto the conveyor belt 7, and then control the telescopic rod of the horizontal cylinder 11 to quickly reset during the process of the disc 3 rotating clockwise by 90° each time (if it takes t seconds for the disc 3 to rotate clockwise by 90° each time, then within the Nth to N + t seconds, the telescopic rod of the horizontal cylinder 11 needs to complete the reset, that is, the telescopic rod of the horizontal cylinder 11 is reset during this time period of switching the station of the material box 8, and the corresponding plate body 10 can be reset smoothly).

[0045] Step C: When the material-containing box 8 on the conveyor belt 7 moves to directly below the pressing member 9 along with the conveyor belt 7, first control the power system of the conveyor belt 7 to stop for 1 - 2 seconds, and then control the pressing member 9 to move downward instantaneously by a preset amount and then quickly reset.

[0046] During use, an operator stands and places an empty material box 1 into the rectangular notch 41 that rotates to the box loading station (0° position). Then, driven by the disk 3, it first rotates to directly below the filling gun 6 (270° position) for filling. After the empty material box 1 is filled, it is called the material-containing box 8. Then it rotates to the side directly opposite the box loading station (180° position), then to the side of the box loading station (90° position). Then, with the help of the horizontal cylinder 11 and the connected plate body 10, the material-containing box 8 is moved onto the conveyor belt 7. As the disk 3 continues to rotate, after the material-containing box 8 is removed, the rectangular notch is left empty and continues to return to the box loading station (0° position) for the next cycle. Then, with the help of the vertical cylinder 12 and the connected pressing member 9, the hot pot ingredients in the material-containing box 8 are compacted and continue to be sent to the freezer by means of the conveyor belt 7.

[0047] Example 2

[0048] The rotary loading system used in this example is as Figure 2 、 Figure 3 shown, and includes a disk 3 connected to the output end of the motor 2. Four evenly arranged rectangular notches are provided on the disk 3 along the circumferential direction, located at the 0° (360°) position, 90° position, 180° position, and 270° position on the circumference respectively. The material box 1 is used to be clamped in the rectangular notch. Above the edge of the disk 3, there is a filling gun 6 of the filling equipment. A conveyor belt 7 is provided on the side directly opposite the filling gun 6. The top surface of the left end of the conveyor belt 7 is located below the edge of the disk 3. During the rotation of the disk 3, all the rectangular notches can successively be located directly below the filling gun 6 and directly above the left end of the conveyor belt 7.

[0049] Among them, a cone 13 is provided above the end of the conveyor belt 7. The cone 13 is vertically arranged and is directly above the fourth rectangular notch 44. The top of the cone 13 is connected to the telescopic rod of the second vertical cylinder 11. The second vertical cylinder 11 is connected to the horizontal cylinder 11. When the second vertical cylinder 11 drives the cone 13 to move down to a preset position, the side wall of the lower part of the cone 13 just contacts the inner wall of the material-containing box 8. When the horizontal cylinder 11 retracts, the material-containing box 8 is scraped onto the conveyor belt 7 with the help of the cone 13.

[0050] A controller is used to realize the intelligent control of the process steps of filling the spicy hot pot base material into boxes. The rotary loading system also includes a controller. The controller is respectively connected to and controls the power systems of the motor 2, the horizontal cylinder 11, the second vertical cylinder 11, and the conveyor belt 7. When the processor of the controller executes its program, the following steps are realized:

[0051] Step S1, control the motor 2 to rotate at a preset frequency and a preset speed, so that the disk 3 rotates 90° clockwise each time and then control the motor 2 to pause for 2 - 3 seconds. When the motor 2 pauses, control the filling equipment to fill the empty material box 1 directly below the filling gun 6.

[0052] In step S2, when the material-containing box 8 filled with spicy hot pot base is located directly below the cone 13, first control the telescopic rod of the second vertical cylinder 11 to extend downward by a preset amount, then control the telescopic rod of the horizontal cylinder 11 to retract, bringing the material-containing box 8 to the conveyor belt 7. Then, during the process of the disc 3 rotating clockwise by 90° each time, control the telescopic rod of the second vertical cylinder 11 to quickly reset, and finally control the telescopic rod of the horizontal cylinder 11 to reset.

[0053] During use, an operator stands and places an empty material box 1 into the rectangular notch 41 that rotates to the box loading station (0° position). Then, driven by the disc 3, it first rotates to directly below the filling gun 6 (270° position) for filling. After the empty material box 1 is filled, it is called the material-containing box 8. Then it rotates to the side directly opposite the box loading station (180° position), then to the side of the box loading station (90° position). Then, use the second vertical cylinder 11 and its connected cone 13 to compact the hot pot material in the material-containing box 8. Then, use the horizontal cylinder 11 to move the material-containing box 8 to the conveyor belt 7, and continue to send it to the freezer via the conveyor belt 7. As the disc 3 continues to rotate, after removing the material-containing box 8, the rectangular notch is left empty and continues to return to the box loading station (0° position) for the next cycle.

[0054] The solution in the embodiment can greatly improve the efficiency of packing the spicy hot pot base. Each set of filling equipment only needs to be equipped with one operator, and the per capita filling volume can be increased to 25 - 45 boxes per minute. Compared with the existing method, the filling cost can be reduced by about 60%. With this solution, the amount of oil spillage is very small, and the operation process is simple, completely avoiding the problem that the compaction process easily causes soreness in the operator's arms. In addition, in the solution of Embodiment 2, the compaction process and the process of transferring the material box are cleverly integrated. By using the cone 13 to extend into the material-containing box 8 to press down the hot pot material and cooperating with the lateral force applied by the horizontal cylinder 11, the material-containing box 8 is brought to the conveyor belt 7, further simplifying the operation process.

[0055] It should be particularly noted that the pressing member 9 (conical body) used in the present invention is a frustum of a cone. The height of the frustum of the cone is equal to the height of the material box, and the frustum of the cone can just smoothly enter and exit the material box and contact the inner wall of the material box. Additionally, Figure 3 The four rectangular notches shown are schematic diagrams in a specific state. When the material box rotates with the disc 3, the positions of the four rectangular notches change adaptively.
