The transmission system is responsible for driving the various components of the syrup filling machine to move. It is usually composed of a motor, a reducer, a transmission shaft, a gear and other components, through precise transmission ratios and matching. The filling system is the core part of the syrup filling machine, which includes a filling bucket, a pumping device and a filling head. The syrup in the sugar tank is poured into the filling bucket through the filling bucket. The pumping device is responsible for extracting viscous materials such as syrup from the filling bucket and transporting them to the filling head through a pipeline. The filling head is the part of the syrup filling machine that contacts the container. It is responsible for accurately injecting viscous materials such as syrup into the container. The design of the filling head usually takes into account the fluidity of the material and the shape of the container to ensure the uniform distribution of the material and the sealing of the container during the filling process.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 To Attachment Figure 6 This application is described in further detail.

[0032] The prior art uses a filling hopper to fill syrup from the inside through an open mouth. When filling syrup, it is necessary to hold the syrup tank and pour it from top to bottom. In the food safety production process, the syrup tank is placed on the filling hopper, and dirt adhered to the outer wall of the syrup tank is easy to fall into the filling hopper. Moreover, the filling hopper is continuously in an open state, and impurities in the air are easy to contaminate the syrup.

[0033] In order to increase the sealing of the filling bucket 2 during the syrup replenishment process, prevent dirt from falling into it, thereby increasing the food safety of the syrup. Therefore, the present application provides an automatic grouting machine. It includes a frame 1, a filling bucket 2, a grouting barrel 3 and a filling module 6. Specifically, the frame 1 is the main structure that carries the filling bucket 2, the grouting barrel 3 and the filling module 6. The filling bucket 2 is a funnel-shaped structure. Further, in order to enable the filling bucket 2 to temporarily store more syrup, the filling bucket 2 uses a combined structure with a cylindrical barrel shape at the top and a conical shell at the bottom, and stores syrup through the cylindrical barrel part. The grouting barrel 3 is horizontally arranged on the frame 1, and the small mouth end at the bottom of the filling bucket 2 is connected to the middle position of the grouting barrel 3. A pouring head 5 is provided at one end of the grouting barrel 3. The syrup in the filling bucket 2 flows into the grouting barrel 3 under the action of gravity. The filling module 6 is arranged in the frame 1, and the filling module 6 is connected to one end of the grouting tube 3, and is used to pressurize the syrup in the grouting tube 3, so that the syrup is squeezed out from the filling head 5 and poured into the food. Further, a sealing cover 4 is arranged in the filling bucket 2, and the sealing cover 4 is coaxially slidably connected in the filling bucket 2, and the diameter of the sealing cover 4 corresponds to the inner diameter of the filling bucket 2. A through hole 411 is opened along the axis on the surface of the sealing cover 4. The automatic grouting machine also includes a feeding module 7. The feeding module 7 is arranged in the frame 1, and one end of the feeding module 7 can be connected to the syrup barrel (a packaging barrel for transporting syrup), and the other end is connected to the through hole 411 through the grouting pipe 71. The feeding module 7 pressurizes the syrup and injects it into the filling bucket 2. As the syrup is injected into the filling bucket 2, the sealing cover 4 is lifted up, and as the liquid level of the syrup rises, the syrup is exposed to the air, which causes syrup contamination.

[0034] Furthermore, in order to increase the stability of the sealing cover 4 when it moves and avoid the sealing cover 4 from tilting. A guide tube 23 is also provided in the filling bucket 2. The guide tube 23 is a circular tube with two ends passing through, and the guide tube 23 is arranged along the axis of the filling bucket 2. One end of the guide tube 23 is connected to the filling bucket 2 through a plurality of support rods 231, and the other end passes through the through hole 411 to connect the grouting pipe 71, and the outer diameter of the grouting pipe 71 is equal to the diameter of the through hole 411. The support rod 231 is arranged perpendicular to the length direction of the guide tube 23, and the middle parts of a plurality of support rods 231 overlap to form a bracket 11 structure. If there are two, it is a cross shape, if there are four, it is a M shape, and so on. The surface of the lower end of the grouting pipe 71 is connected to the support rod 231, and the end of the support rod 231 is connected to the inner wall of the filling bucket 2.

[0035] Furthermore, in order to increase the stability of the sealing cover 4 when it moves and prevent the sealing cover 4 from rotating. A plurality of first limit blocks 42 are arranged at intervals on the outer peripheral side of the sealing cover 4. The inner wall of the filling bucket 2 is provided with a number of first limit grooves 221 corresponding to the first limit blocks 42, and the first limit grooves 221 are opened along the axial direction of the filling bucket 2. The first limit block 42 slides in the first limit groove 221. It is worth noting that in order to make the sliding of the sealing cover 4 more stable, the sealing cover 4 needs to slide only on the barrel part 211 of the filling bucket 2. However, in order to further reduce the residual syrup in the filling bucket 2, the sealing cover 4 can be set to a downwardly concave shape to adapt to the conical shell part, so that less syrup remains.

[0036] Further, in order to reduce the adhesion of syrup to the surface of the guide tube 23, a sealing scraper ring 41 is provided in the middle of the sealing cover 4. The through hole 411 is the space surrounded by the inner circle of the sealing scraper ring 41, and the sealing hanging ring can slide along the axial direction of the guide tube 23 to scrape off the syrup.

[0037] Further, in order to facilitate the observation of the remaining amount of syrup in the filling bucket 2. The automatic grouting machine also includes a metering tube 24. The metering tube 24 is a round tube structure with two ends connected. The metering tube 24 is coaxially sleeved on the outside of the guide tube 23, and the inner diameter of the metering tube 24 is equal to the outer diameter of the guide tube 23. The bottom of the metering tube 24 is connected to the surface of the sealing scraper ring 41. The metering tube 24 can slide axially along the guide tube 23. The grouting pipe 71 is connected to the guide tube 23 by connecting the metering tube 24. The lengths of the metering tube 24 and the guide tube 23 are both greater than or equal to the depth of the filling bucket 2. When the syrup is injected into the filling bucket 2, the sealing cover 4 is pushed to move upward, thereby driving the metering tube 24 to slide upward, and the metering tube 24 extends out of the extension surface of the upper surface of the filling bucket 2. As the syrup is continuously injected, the metering tube 24 continues to rise. The staff observes the height of the metering tube 24 from any position, thereby judging the amount of syrup in the filling bucket 2, and then judging whether the syrup needs to be added.

[0038] Furthermore, the amount of syrup that can be filled into the filling bucket 2 at a time is limited by the depth of the filling bucket 2. That is, syrup that exceeds the depth of the filling bucket 2 cannot be added. During the period when the order volume surges, the staff needs to frequently replace the syrup barrel. To this end, the filling bucket 2 includes a basic bucket body 21 and an expansion barrel 22. The basic bucket body 21 includes a barrel portion 211 and a conical portion 212. The conical portion 212 connects the grouting barrel 3 and the guide tube 23. The expansion barrel 22 is a circular tube structure with two ends through. The sealing cover 4 is arranged in the expansion barrel 22, and the expansion barrel 22 is coaxially slidably connected to the barrel portion 211. The first limiting groove 221 is arranged in the expansion barrel 22. As the syrup is filled, the sealing cover 4 is pushed by the syrup and moves from the bottom of the expansion barrel 22 to the top. The filling continues, and the sealing cover 4 and the expansion barrel 22 move synchronously and extend out of the basic bucket body 21. After adding the expansion barrel 22, the staff can adjust the total amount of syrup injected at a time according to the multiples of the order quantity, so as to obtain a single syrup injection amount that is several times more than usual, reduce the time spent waiting for the syrup to be consumed and continue to refill, and increase the overall production efficiency. In addition, since the outer diameter of the expansion barrel 22 is equal to the inner diameter of the cylindrical portion 211 of the basic bucket body 21. That is, the expansion barrel 22 can scrape the inner wall of the filling bucket 2 when moving downward, so that the syrup is scraped off, reducing the hardening of the syrup attached to the inner wall after oxidation, making the raw materials safer.

[0039] Furthermore, a plurality of second limit blocks 222 are circumferentially arranged on the outer wall of one end of the expansion tube 22 close to the grouting tube 3. A second limit groove 213 for sliding the corresponding second limit block 222 is opened on the inner wall of the basic bucket body 21, and the second limit groove 213 is opened along the length direction of the basic bucket body 21.

[0040] Specifically, the filling module 6 includes a piston bolt 61, a first one-way ball 62, a first elastic member 63 and a first driving assembly. The grouting tube 3 is a hollow circular tube structure, and the grouting tube 3 is axially divided into an injection chamber 31, a transition chamber 32 and a check chamber 33 which are connected end to end in sequence. Among them, the diameter of the transition chamber 32 is smaller than that of the injection chamber 31 and the check chamber 33. The piston bolt 61 is coaxially slidably connected in the injection chamber 31, and one end of the piston bolt 61 passes through the grouting tube 3 to the frame 1 in a direction away from the transition chamber 32. The first driving assembly is arranged in the frame 1, and is used to control the sliding of the piston bolt 61. The diameter of the piston bolt 61 is equal to the inner diameter of the injection chamber 31. The filling bucket 2 is connected to the middle part of the injection chamber 31 near the transition chamber 32. The piston bolt 61 can block the filling bucket 2 after moving in the direction of the transition chamber 32, and can also connect the filling bucket 2 and the injection chamber 31 after sliding in the direction away from the transition chamber 32. Chamfers are arranged at both ends of the transition chamber 32. The first one-way ball 62 and the first elastic member 63 are both arranged in the check cavity 33, and the first elastic member 63 is a spring. The first elastic member 63 is arranged axially along the check cavity 33. The first elastic member 63 has a tendency to always push the first one-way ball 62 toward the injection cavity 31, that is, the first elastic member 63 pushes the first one-way ball 62 to abut against one end of the transition cavity 32, blocking the connection between the transition cavity 32 and the check cavity 33. The filling head 5 is connected to the check cavity 33. When the piston bolt 61 slides to allow the syrup to enter the injection cavity 31, the piston bolt 61 slides to push the syrup into the transition cavity 32. At this time, the syrup is pressurized, and the first one-way ball 62 is pushed by force. At this time, the first elastic member 63 is compressed, and the syrup is pressed into the check cavity 33 and enters the filling head 5 at the same time to proceed to the next step. After the syrup pressure is released, the first elastic member 63 recovers to reset the first one-way ball 62.

[0041] Specifically, the pouring head 5 includes a pouring tube 51, a rotating shaft 52, a spiral piece 53, a rotating motor 54 and a mold end 55. The pouring head 5 is arranged perpendicular to the length direction of the grouting tube 3. The pouring tube 51 includes a buffer chamber 511 and a compression chamber 512, and the buffer chamber 511 and the compression chamber 512 are coaxially connected. The grouting tube 3 is connected to the buffer chamber 511. The compression chamber 512 is located below the buffer chamber 511. The rotating shaft 52 is coaxially rotatably connected to the pouring tube 51, and the rotating motor 54 is arranged on the outer wall of the upper end of the pouring tube 51. The output end of the rotating motor 54 is connected to the rotating shaft 52 to drive the rotating shaft 52 to rotate. The rotating shaft 52 enters the compression chamber 512 through the buffer chamber 511 and is connected to the spiral piece 53. The outer diameter of the spiral piece 53 is equal to the inner diameter of the compression chamber 512. The inner diameter of the buffer chamber 511 is larger than the inner diameter of the compression chamber 512. The die end 55 is arranged at the bottom of the filling head 5, and is connected to the compression chamber 512, and is used to extrude the syrup into the required style. The die end 55 can be set in different structures according to the shape or number of syrups to be added, which belongs to the prior art and will not be described here. The syrup is pressurized and sent into the buffer chamber 511 for temporary storage. Under the action of pressure or gravity, the syrup flows into the spiral sheet 53. After the rotating shaft 52 rotates, the syrup is compressed and extruded by the die end 55, and the food is filled with syrup.

[0042] Specifically, the feeding module 7 includes a feeding pipe 72, a feeding barrel 73, a piston block 76 and a second drive assembly 77. The feeding module 7 is arranged in the frame 1. One end of the feeding pipe 72 is connected to the feeding barrel 73, and the other end is a free end that can be inserted into the syrup barrel. The feeding pipe 72 is inserted into the syrup barrel to extract syrup. It is worth noting that there should be a gap between the feeding pipe 72 and the opening of the syrup barrel to allow a small amount of air to enter to prevent pressure imbalance and difficulty in slurry feeding. The feeding barrel 73 is a cylindrical hollow shell structure, and the piston block 76 is coaxially slidably connected to the feeding barrel 73, and the diameter of the piston block 76 is equal to the inner diameter of the feeding barrel 73. The second drive assembly 77 is arranged in the frame 1 to drive the piston block 76 to reciprocate in the feeding barrel 73. The other end of the grouting pipe 71 is connected to the feeding barrel 73. Through the reciprocating motion of the piston block 76 , negative pressure is formed in the upper barrel 73 or the interior of the upper barrel 73 is squeezed, and the syrup in the syrup barrel is drawn through the upper pipe 72 and injected into the filling hopper 2 through the injection pipe 71 .

[0043] Further, in order to prevent the syrup from flowing back. A feed pipe 74 and a discharge pipe 75 are provided at one end of the upper barrel 73 away from the second drive assembly 77. The upper barrel 73 is connected to the feed pipe 74, and the discharge pipe 75 is connected to the grouting pipe 71.

The main shaft of the first crankshaft 64 is rotatably connected to the frame 1 through the bracket 11, the crank neck of the first crankshaft 64 is rotatably connected to the first connecting rod 642, and the other end of the first connecting rod 642 is rotatably connected to the tail end of the piston bolt 61. The second drive assembly 77 includes a second crankshaft 78, a second connecting rod 782 and a second power source. The main shaft of the second crankshaft 78 is rotatably connected to the frame 1 through the bracket 11, the crank neck of the second crankshaft 78 is rotatably connected to the second connecting rod 782, and the other end of the second connecting rod 782 is rotatably connected to the tail end of the piston block 76.

[0045] In other embodiments, the first power source and the second power source may be provided separately.

[0046] In this embodiment, when the filling module 6 is working, the feeding module 7 should be in a stopped state to maintain the internal pressure balance and ensure the normal operation of the equipment. Similarly, when the feeding module 7 is working, the filling module 6 should be stopped. Therefore, in order to reduce the production cost and electricity cost of the equipment, only a single motor can be set to drive the first drive component and the second drive component 77 to work, that is, the first power source and the second power source are driven by the same drive motor. For this reason, the automatic grouting machine is also provided with a switching component 8 for connecting the kinetic energy of the drive motor to the required drive component.

[0047] Specifically, the main shafts of the first crankshaft 64 and the second crankshaft 78 are on the same straight line, and the ends of the first crankshaft 64 and the second crankshaft 78 are spaced apart. The switching assembly 8 includes a sliding seat 81, a driving gear 82, a driven gear 83 and a toothed chain 821. The sliding seat 81 is slidably connected in the frame 1. The sliding seat 81 is located in the interval between the ends of the first crankshaft 64 and the second crankshaft 78. The axis of the driven gear 83 coincides with the axis of the main shaft of the first crankshaft 64. The driving gear 82 and the driven gear 83 are both rotatably connected to the sliding seat 81. The driving motor is arranged on the sliding seat 81, and the output end of the driving motor 85 is coaxially connected to the driving gear 82, thereby driving the driving gear 82 to rotate, and the driving gear 82 transmits power to the driven gear 83 through the toothed chain 821. The driven gear 83 is rotatably connected to the sliding seat 81 through the relay shaft 831. Both ends of the relay shaft 831 pass through the sliding seat 81 and are respectively provided with a first docking piece 832. The opposite ends of the first crankshaft 64 and the second crankshaft 78 are respectively provided with a second docking piece 641 and a third docking piece 781. The first docking piece 832 can abut against the second docking piece 641 or the third docking piece 781 after the sliding seat 81 moves. The surfaces of the first docking piece 832, the second docking piece 641 and the third docking piece 781 are all roughened. The switching assembly 8 also includes a driving screw 84 for driving the sliding seat 81 to move. A driving block 811 is provided at one end of the sliding seat 81. The driving screw 84 is vertically rotatably connected to the frame 1. The driving screw 84 passes through the driving block 811 and is threadedly connected thereto. One end of the driving screw 84 is not provided with a thread, and the end passes through the frame 1 upward and is provided with a knob 841. The end of the sliding seat 81 is also provided with a protrusion 812, and the inner wall of the frame 1 is provided with a groove 12 for the protrusion 812 to slide. A button for adjusting the rotation rate of the driving motor is provided on the surface of the frame 1. By rotating the driving screw 84 to drive the sliding seat 81 to slide, the protrusion 812 and the groove 12 cooperate to limit the rotation of the sliding seat 81, so that the sliding seat 81 slides smoothly. When the first docking piece 832 and the second docking piece 641 abut, the power is transmitted to the first crankshaft 64. When the first docking piece 832 and the second docking piece 641 abut, the power is transmitted to the second crankshaft 78.

[0048] The implementation principle of an automatic grouting machine in the embodiment of the present application is: The loading module 7 pressurizes the syrup and injects it into the filling hopper 2. As the syrup is injected into the filling hopper 2, the sealing cover 4 is lifted up. As the syrup is injected, the sealing cover 4 is pushed by the syrup and moves from the bottom of the expansion barrel 22 to the top. The filling continues, and the sealing cover 4 and the expansion barrel 22 move synchronously and extend out of the basic bucket body 21. The sealing cover 4 provides a sealed environment to prevent the syrup from being exposed to the air for a long time. The expansion barrel 22 allows the filling hopper 2 to exceed its original capacity and process more syrup at a time. When the syrup is injected into the filling hopper 2, the sealing cover 4 is pushed to move upward, and the metering tube 24 extends out of the extension surface of the upper surface of the filling hopper 2, making it convenient for the staff to observe the amount of syrup in the filling hopper 2.

[0049] The reciprocating motion of the piston block 76 forms a negative pressure in the upper barrel 73 or squeezes the interior of the upper barrel 73, extracts syrup from the syrup barrel through the upper barrel 72, and injects the syrup into the filling hopper 2 through the injection pipe 71. Due to the pressurization of the upper barrel 73 and the piston block 76, the sealing cover 4 is more easily lifted.

[0050] When the piston bolt 61 slides and allows the syrup to enter the injection chamber 31, the piston bolt 61 slides and pushes the syrup into the transition chamber 32. At this time, the syrup is pressurized, and the first one-way ball 62 is pushed by the force. At this time, the first elastic member 63 is compressed, and the syrup is pressed into the check chamber 33 and enters the filling head 5 at the same time, thereby adding syrup to the food.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
