Description

Technical Field

[0001] This invention belongs to the field of filling equipment technology, specifically relating to an automatic filling equipment for compound sauces. Background Technology

[0002] Automatic filling equipment for compound sauces belongs to the field of food packaging equipment technology. It is a special machine for the automated filling of various compound sauces. The equipment is mainly used to accurately fill different types of compound sauces into bottles, cans and other containers, and is adapted to the large-scale production needs of the food processing industry.

[0003] In current sauce filling methods, the filling nozzle is usually located at the bottle opening or extends deep into the bottle for filling. The filling nozzle is fixed and suspended at the bottle opening, and the sauce falls vertically under gravity or pump pressure, directly impacting the center area of ​​the bottle bottom. Then, it naturally spreads outwards due to the fluidity of the material itself. This filling method is suitable for thin sauces with low viscosity and excellent fluidity. The filling nozzle extends deep into the bottle bottom to reduce the drop and prevent material splashing. As the liquid level of the sauce in the bottle rises, the filling nozzle is slowly raised in sync, always keeping the filling nozzle slightly above the liquid surface. This method is mainly suitable for sauces with medium viscosity and a semi-fluid state.

[0004] For high-viscosity compound sauces, traditional filling methods involve vertically lifting and fixing the filling process along the central axis of the bottle. However, due to the extremely poor fluidity of viscous compound sauces, they lack the ability to spread and level out naturally as the liquid level rises. In this situation, the newly injected sauce continuously impacts the central area of ​​the bottle bottom, piling up on top of the existing central pile. This results in the sauce being much higher in the center than around the perimeter, ultimately forming a pyramid-shaped accumulation. On one hand, the excessive concentration of sauce in the center prevents rapid filling of the surrounding area, creating numerous gaps and leading to uneven filling and insufficient effective volume. On the other hand, as the central level rises, the bulging sauce pile gradually overflows the filling nozzle, blocking it and hindering normal sauce flow. This also causes a sharp increase in internal pressure within the filling pipeline, severely impacting filling stability. Summary of the Invention

[0005] This invention provides an automatic filling device for compound sauces, which solves the technical problems mentioned in the background art.

[0006] This invention provides an automatic filling device for compound sauces, including a conveyor, a clamping component, a support plate, a lifting plate, and a filling tube. The clamping component is installed on the conveyor, the support plate is fixedly connected to the conveyor, the lifting plate is driven to move up and down along the height of the support plate, and the filling tube is located at the lower part of the lifting plate. The filling tube is driven to rotate and move horizontally at the lower part of the lifting plate. The lower part of the lifting plate is equipped with a driving component, which is used to drive the filling tube to rotate and move horizontally.

[0007] In a preferred embodiment, the driving component includes a motor, which is fixedly connected to the upper part of the lifting plate. The driving end of the motor passes through the lifting plate, and a rotating plate is fixedly connected to the driving end of the motor. A second electric push rod and two fixed plates are fixedly connected to the lower part of the rotating plate. Two sliding rods are fixedly connected between the two fixed plates, and sliding plates are slidably connected to the two sliding rods. The driving end of the second electric push rod passes through one of the fixed plates and is fixedly connected to one side of the sliding plate. The upper end of the filling tube is fixedly connected to the lower part of the sliding plate.

[0008] In a preferred embodiment, two sliding holes are provided on the sliding plate, and the sliding rod is located inside the sliding holes and forms a sliding guide engagement with the sliding holes.

[0009] In a preferred embodiment, an electric actuator is fixedly connected to the upper part of the support plate, the drive end of the electric actuator is fixedly connected to the lifting plate, and the lifting plate is slidably connected to the support plate.

[0010] In a preferred embodiment, the lower end of the filling tube is provided with an extension member, which includes a fixed tube and an extension tube. The fixed tube is fixedly connected to the filling tube, and the extension tube is driven to reciprocate along the axial direction of the fixed tube.

[0011] In a preferred embodiment, an electric actuator three is fixedly connected to one side of the fixed tube. The electric actuator three is used to drive the extension tube to reciprocate along the axial direction of the fixed tube inside the fixed tube. The driving end of the electric actuator three is fixedly connected to one side of the extension tube.

[0012] In a preferred embodiment, the internal chamber of the fixed tube and the internal chamber of the filling tube are connected, and the axis of the fixed tube and the axis of the extending tube are collinear.

[0013] In a preferred embodiment, limit blocks are fixedly connected to both sides of the protruding tube, and two limit grooves are opened inside the fixed tube. The groove direction of the limit groove is consistent with the length direction of the fixed tube. The limit blocks are located in the limit grooves and form a sliding guide engagement with the limit grooves.

[0014] In a preferred embodiment, a bending element is provided at the end of the protruding tube away from the fixed tube. The bending element includes a corrugated tube and a spring. The spring is sleeved on the outer periphery of the corrugated tube, and the corrugated tube is fixedly connected to the end of the protruding tube.

[0015] In a preferred embodiment, the axis of the bellows, the axis of the spring, and the axis of the extension tube are collinear.

[0016] The beneficial effects of this invention are as follows: This invention achieves "spiral trajectory filling" of the filling tube by coordinating a motor, electric push rod one, electric push rod two, rotating plate, sliding plate and filling tube. This allows the viscous sauce to spread from the edge of the bottle wall to the center, forming a continuous and uniform spiral layer distribution inside the bottle. This effectively solves the problems of center accumulation, periphery void and internal air bubble residue caused by the poor fluidity of viscous sauce.

[0017] Because the filling tube spirals upwards along the bottle wall, the discharge point is always located at the highest point of the current liquid level, which avoids the accumulation of viscous sauce that overflows the filling tube, causing a sharp increase in pumping resistance and resulting in the actual discharge flow rate being less than the set flow rate, thus leading to insufficient filling volume.

[0018] This invention utilizes the combination of an electric push rod, a fixed tube, and an extension tube to achieve a physical barrier to prevent leakage between the extension tube extending close to the inner wall of the narrow-mouth bottle during filling and the non-filling state of the filling tube. This allows the dispensing point to be precisely extended to the edge of the inner wall of the narrow-mouth bottle, while preventing viscous sauce from dripping or sticking prematurely. Simultaneously, due to the rotation of the filling tube, residual viscous sauce in the horizontally arranged extension tube can be flung out, avoiding the problem of residual viscous sauce dripping from the extension tube.

[0019] The present invention uses an extension tube, a corrugated tube, and an outer peripheral spring to achieve adaptive flexible bending at the filling end and continuous material discharge at the bottleneck section. It conforms to the curvature of the inner wall of the slender bottleneck to keep the material discharge channel unobstructed and is suitable for continuous filling of irregularly shaped narrow-mouth bottles.

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] like Figure 1 , Figure 2 As shown, an automatic filling device for compound sauce includes a conveyor 1, a clamping member 11, a support plate 13, a lifting plate 14, and a filling tube 15. The clamping member 11 is installed on the conveyor 1, the support plate 13 is fixedly connected to the conveyor 1, the lifting plate 14 is driven to move up and down along the height of the support plate 13, and the filling tube 15 is arranged at the lower part of the lifting plate 14. The filling tube 15 is driven to rotate and move horizontally at the lower part of the lifting plate 14. A drive unit 3 is provided at the lower part of the lifting plate 14. The drive unit 3 is used to drive the filling tube 15 to rotate and move horizontally.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the driving component 3 includes a motor 31, which is fixedly connected to the upper part of the lifting plate 14. The driving end of the motor 31 passes through the lifting plate 14. The driving end of the motor 31 is fixedly connected to a rotating plate 32. The lower part of the rotating plate 32 is fixedly connected to an electric push rod 33 and two fixed plates 36. Two sliding rods 34 are fixedly connected between the two fixed plates 36. A sliding plate 35 is slidably connected to the two sliding rods 34. The driving end of the electric push rod 33 passes through one of the fixed plates 36 and is fixedly connected to one side of the sliding plate 35. The upper end of the filling tube 15 is fixedly connected to the lower part of the sliding plate 35. It is necessary to add that, such as Figure 4 , Figure 6 As shown, two sliding holes are provided on the sliding plate 35, and the sliding rod 34 is located inside the sliding hole and forms a sliding guide fit with the sliding hole, that is, the sliding rod 34 is slidably connected to the sliding plate 35 through the sliding hole; It is necessary to add that, such as Figure 3 and Figure 4As shown, the initial position of the filling tube 15 is when the axis of the filling tube 15 and the axis of the drive end of the motor 31 are collinear. The length direction of the fixing plate 36 is consistent with the radial direction of the motor 31. When the sliding plate 35 moves along the fixing plate 36, the filling tube 15 can move in the radial direction of the motor 31. Specifically, such as Figure 1 , Figure 2 As shown, an electric actuator 2 is fixedly connected to the upper part of the support plate 13. The drive end of the electric actuator 2 is fixedly connected to the lifting plate 14, and the lifting plate 14 is slidably connected to the support plate 13. It is necessary to add that, such as Figure 1 , Figure 2 As shown, the clamping component 11 includes two clamping plates and two hydraulic rods. The clamping plates are fixedly connected to the drive end of the hydraulic rods. The two hydraulic rods are symmetrically arranged and fixedly connected to the conveyor 1. This is prior art and will not be described in detail. It is necessary to add that, such as Figure 1 , Figure 2 As shown, multiple bottles 12 are provided on the upper part of the conveyor 1. The bottles 12 are containers for filling sauces.

[0032] Since the data for bottles 12 from the same batch is known, the data for bottles 12 can be input into the device before operation. The device can then adjust the operating parameters of each component based on the data. Alternatively, distance sensors can be installed at the bottom and sidewalls of the filling tube 15 to read the distance between the filling tube 15 and the bottles 12 in real time. During operation, bottles 12 are conveyed at a uniform speed by the conveyor 1 and precisely carried between the two clamping plates of the clamping member 11. At this point, the clamping member 11 is activated, and its built-in hydraulic rod drives the clamping plates to clamp symmetrically, firmly fixing the bottles 12 and preventing them from shaking or shifting during filling. After the bottles 12 are fixed, the electric push rod 2 is activated. The drive end drives the lifting plate 14 to slide vertically downward smoothly along the support plate 13, causing the filling tube 15 at the bottom of the lifting plate 14 to move downward until the filling tube 15 is inserted into the bottle 12. In the initial state, the filling tube 15 is precisely aligned with the central axis of the bottle 12, ensuring that the initial insertion position is centered. To overcome the physical characteristics of poor viscosity and difficulty in spreading naturally, the electric push rod 33 is activated, and its drive end pushes the sliding plate 35 to slide horizontally, and the filling tube 15 moves slowly from the center of the bottle 12 to the inner wall edge of the bottle. When the filling tube 15 approaches the inner wall of the bottle 12, the electric push rod 33 stops, locking the radial position of the filling tube 15. Then, the motor 31 starts to drive... The rotating plate 32 rotates uniformly around the central axis of the bottle 12; the rotating plate 32 drives the filling tube 15 below it to revolve, causing the filling tube 15 to move in a circular motion along the inner wall of the bottle 12; while the filling tube 15 continues to rotate in a circular motion, the electric push rod 2 starts slowly in the opposite direction, uniformly pushing the lifting plate 14 to move vertically upward along the support plate 13, causing the filling tube 15 to revolve along the inner wall while slowly rising upward; during this process, the filling tube 15 opens to discharge, and the viscous sauce is sprayed out uniformly from the filling tube 15. With the revolve and slow rising motion of the filling tube 15, the viscous sauce forms a continuous and uniform spiral distribution from bottom to top at the bottom of the bottle 12, thereby making the filling tube 15 revolve in a circular motion. The viscous sauce can quickly fill the hollow part of the bottle 12. Through the cooperation of the motor 31, the filling tube 15 and the electric push rod, the "spiral trajectory filling" of the filling tube 15 is realized, allowing the viscous sauce to spread from the edge of the bottle wall to the center, so that the viscous sauce forms a continuous and uniform spiral layer distribution in the bottle. This effectively solves the problems of center accumulation, periphery void and internal air bubble residue caused by the poor fluidity of the viscous sauce. Since the filling tube 15 rises spirally along the bottle wall, the discharge point is always located at the edge of the current liquid level, avoiding the problem of viscous sauce accumulating and overflowing the filling tube 15, which would cause the pumping resistance to increase sharply and the actual discharge flow rate to be less than the set flow rate, resulting in insufficient filling volume.

[0033] In the above embodiments, such as Figure 5 , Figure 6As shown, when filling a bottle 12 with a narrow neck and constricted neck, the filling tube 15 can only reach the neck of the bottle 12 due to the limitations of the bottle structure. It cannot go deeper into the bottle body. At this time, a significant gap will be formed between the lower end of the filling tube 15 and the inner wall of the bottle. If filling is done directly in this state, the viscous sauce will accumulate directly in the middle of the bottle 12 and the inner diameter area of ​​the neck due to its poor fluidity. This will not only cause uneven filling and voids in the bottle, but also easily cause the filling tube 15 to be blocked by the accumulated viscous sauce, affecting the normal operation of the equipment. Therefore, in order to solve this technical problem, in this embodiment, the lower end of the filling tube 15 is provided with an extension 4. The extension 4 includes a fixed tube 41 and an extension tube 42. The fixed tube 41 is fixedly connected to the filling tube 15, and the extension tube 42 is driven to move back and forth along the axial direction of the fixed tube 41.

[0034] Specifically, such as Figure 5 , Figure 6 As shown, an electric actuator 3 5 is fixedly connected to one side of the fixed tube 41. The electric actuator 3 5 is used to drive the extension tube 42 to reciprocate along the axial direction of the fixed tube 41 inside the fixed tube 41. The driving end of the electric actuator 3 5 is fixedly connected to one side of the extension tube 42. It is necessary to add that, such as Figure 5 , Figure 6 As shown, the internal chamber of the fixed tube 41 is connected to the internal chamber of the filling tube 15. The axis of the fixed tube 41 and the axis of the extension tube 42 are collinear. Limiting blocks 421 are fixedly connected to both sides of the extension tube 42. Two limiting grooves 411 are opened inside the fixed tube 41. The groove direction of the limiting grooves 411 is consistent with the length direction of the fixed tube 41. The limiting blocks 421 are located in the limiting grooves 411 and form a sliding guide fit with the limiting grooves 411. That is, the limiting blocks 421 are slidably connected to the fixed tube 41 through the limiting grooves 411, that is, the extension tube 42 is slidably connected to the fixed tube 41. It is necessary to add that, such as Figure 5 , Figure 6 As shown, the extension tube 42 has an extended state and a retracted state. The retracted state is the initial state of the extension tube 42. When the extension tube 42 is in the retracted state, the extension tube 42 is located inside the fixed tube 41, and the limiting block 421 is located in the limiting groove 411 away from the connection between the electric push rod 3 5 and the extension tube 42. At this time, the side wall of the extension tube 42 blocks the lower end of the filling tube 15, and the filling tube 15 is separated from the fixed tube 41. When the extension tube 42 is in the extended state, the extension tube 42 extends partially from the fixed tube 41, and the limiting block 421 is located in the limiting groove 411 near the connection between the electric push rod 3 5 and the extension tube 42. At this time, the filling tube 15 and the fixed tube 41 are connected.

[0035] Before filling, the extension tube 42 is in a retracted state, completely retracted into the fixed tube 41. At this time, the side wall of the extension tube 42 blocks the lower end of the filling tube 15, isolating the filling tube 15 from the internal cavity of the fixed tube 41 to prevent premature leakage of viscous sauce. When the filling tube 15 descends and reaches the neck of the bottle 12 and locks in its radial position, the electric push rod 35 immediately starts. Its drive end drives the extension tube 42 to extend smoothly and horizontally along the axis of the fixed tube 41. When the end of the extension tube 42 approaches the inner wall edge of the bottle 12, the electric push rod 35 stops. The filling tube 15, driven by the motor 31 and the electric push rod 2, makes a spiral upward movement. During this process, the filling tube 15 opens... The viscous sauce flows from the filling tube 15 into the connected fixed tube 41, and then out through the end of the extension tube 42, reaching the inner edge of the bottle 12. When the extension tube 42 spirals upward with the filling tube 15 to the neck of the bottle 12, the electric actuator 35 reverses its direction, causing the extension tube 42 to retract smoothly along the axis of the fixed tube 41. At this time, the side wall of the extension tube 42 re-seals the lower end of the filling tube 15, again isolating the internal chambers of the filling tube 15 and the fixed tube 41. After the extension tube 42 retracts, the filling tube 15 continues to spiral upward at a uniform speed under the coordinated drive of the motor 31 and the electric actuator 2 until it reaches the preset height of the bottle 12. After the entire bottle is filled, the motor 31, electric push rod 1 2, and electric push rod 3 5 reset sequentially, driving the filling tube 15 to rise to its initial high position. The extension tube 42 switches from the extended state to the retracted state. During the retraction process of the filling tube 15, the centrifugal force on the extension tube 42 can throw out the residual material inside the extension tube 42, thereby achieving the function of cleaning the extension tube 42. Subsequently, the clamping member 11 is released, and the conveyor 1 sends away the filled bottle 12. All components of the equipment return to the initial standby state, preparing for the next round of narrow-neck bottle filling cycle. This invention drives the extension tube 42 to reciprocate within the fixed tube 41 via electric push rod 3 5. The linear motion enables the filling tube 15 to have a "variable length" filling end. When the filling tube 15 enters the filling stage, the extension tube 42 extends horizontally in a controlled manner, extending the discharge point to the edge of the inner wall of the bottle. In conjunction with the spiral motion of the filling tube 15, it forces the viscous sauce to fill close to the bottle wall, avoiding the technical problem that the viscous sauce can only accumulate in the projected area of ​​the bottle neck and cannot spread to the edge. Furthermore, in the initial stage of filling, the extension tube 42 is in a retracted state, and its side wall actively seals the lower end of the filling tube 15, forming a physical barrier while self-cleaning part of the viscous sauce inside the extension tube 42. This effectively prevents the viscous sauce from dripping or sticking due to gravity when not in operation, keeping the equipment clean.

[0036] In the above embodiments, such as Figure 7 , Figure 8As shown, when the extension tube 42 moves spirally upward with the filling tube 15 to the neck of the bottle 12, the electric push rod 3 5 drives the extension tube 42 to switch from the extended state to the retracted state. At this time, the side wall of the extension tube 42 re-blocks the material outlet channel at the lower end of the filling tube 15, which directly causes the filling and material outlet to be interrupted. The viscous sauce from the neck to the bottle mouth cannot be replenished normally. On the one hand, in order to replenish the filling volume, it is necessary to extend the filling time or replenish the material twice, which breaks the continuous filling rhythm and greatly reduces the filling efficiency of narrow-mouth bottles. It cannot be adapted to automated mass production. On the other hand, the equipment cannot complete the continuous filling of the entire neck-type narrow-mouth bottle. The equipment can only be adapted to conventional wide-mouth bottles. Its adaptability to irregular narrow-mouth bottles is severely limited, and its production flexibility is insufficient. Therefore, in order to solve this technical problem, in this embodiment, a bending member 6 is provided at the end of the extension tube 42 away from the fixed tube 41. The bending member 6 includes a corrugated tube 61 and a spring 62. The spring 62 is sleeved on the outer periphery of the corrugated tube 61, and the corrugated tube 61 is fixedly connected to the end of the extension tube 42.

[0037] It is necessary to add that, such as Figure 7 , Figure 8 As shown, the axis of the bellows 61, the axis of the spring 62, and the axis of the protruding tube 42 are collinear.

[0038] As the filling tube 15 drives the extension tube 42 to continuously revolve along the bottle wall and slowly spiral upward, the filling operation continues. When the bending component 6 at the end of the extension tube 42 moves to the constriction section of the bottle neck 12, the inner diameter of the bottle neck gradually decreases, which creates a radially inward squeezing force on the corrugated tube 61 protruding from the end of the extension tube 42 and the spring 62 sleeved on the outer periphery. The corrugated tube 61 adaptively bends and deforms with the constriction arc of the inner wall of the bottle neck, and the spring 62 on the outer periphery simultaneously undergoes elastic bending, conforming to the arc contour of the inner wall of the bottle neck, avoiding hard contact between rigid components and the bottle neck. During this adaptive bending process, the discharge channel inside the corrugated tube 61 remains unobstructed, and viscous sauce can still flow continuously out along the inner wall of the bottle neck through the end of the corrugated tube 61, maintaining the spiral filling trajectory. Interruption; Through the cooperation of the extension tube 42, the corrugated tube 61, and the spring 62, when the equipment is filling a bottle 12 with a slender neck, the corrugated tube 61 can flexibly bend and deform with the curvature of the bottle wall under the squeezing action of the narrowing inner diameter of the neck. With the synchronous elastic support of the outer peripheral spring 62, the filling end has the ability to "fit the bottle shape". This allows the filling tube 15 to smoothly transition from the bottle body to the neck area for continuous filling without interrupting the spiral trajectory. This effectively solves the technical problem that traditional rigid filling heads are prone to hard friction damage to the bottle wall when passing through the neck, or even equipment shutdown due to jamming. It not only ensures the full filling of viscous sauce in the neck area, but also significantly extends the service life and application range of the filling equipment.

[0039] The overall working principle of this invention: During operation, the bottle 12 is conveyed at a constant speed by the conveyor 1 and precisely carried between the two clamping plates of the clamping member 11. At this time, the clamping member 11 is activated, and its built-in hydraulic rod drives the clamping plates to clamp symmetrically, firmly fixing the bottle 12 and preventing the bottle from shaking or shifting during the filling process. After the bottle 12 is fixed, the electric push rod 2 is activated, and its driving end drives the lifting plate 14 to slide vertically downward smoothly along the support plate 13, which in turn drives the filling tube 15 at the bottom of the lifting plate 14 to move downward until the filling tube 15 is inserted into the bottle 12. In the initial state, the filling tube 15 is precisely aligned with the center of the bottle 12. The central axis ensures the initial bottle placement is centered. To overcome the poor flowability and difficulty in naturally spreading of viscous sauces, the electric push rod 33 is activated, its drive end pushing the sliding plate 35 to slide horizontally, causing the filling tube 15 to slowly move from the center of the bottle 12 towards the inner wall edge. When the filling tube 15 approaches the inner wall of the bottle 12, the electric push rod 33 stops, locking the radial position of the filling tube 15. Then, the motor 31 starts, driving the rotating plate 32 to rotate uniformly around the central axis of the bottle 12. The rotating plate 32 causes the filling tube 15 below it to revolve, making the filling tube 15 revolve around the inner wall of the bottle 12. It moves in a circular motion along the inner wall; while the filling tube 15 continues to rotate in a circular motion, the electric actuator 2 starts slowly in the opposite direction, pushing the lifting plate 14 vertically upward along the support plate 13 at a uniform speed, so that the filling tube 15 revolves along the inner wall while slowly rising upward; during this process, the filling tube 15 opens to discharge, and the viscous sauce is sprayed out from the filling tube 15 at a uniform speed. With the revolution and slow rise of the filling tube 15, the viscous sauce forms a continuous and uniform spiral distribution from bottom to top at the bottom of the bottle 12, thereby allowing the viscous sauce to quickly fill the hollow part of the bottle 12; through the motor 31 The cooperation between the filling tube 15 and the electric actuator enables the "spiral trajectory filling" of the filling tube 15, allowing the viscous sauce to spread from the edge of the bottle wall to the center, forming a continuous and uniform spiral layer distribution inside the bottle. This effectively solves the problems of center accumulation, periphery voids, and internal air bubble residue caused by the poor fluidity of viscous sauce. As the filling tube 15 spirals upward along the bottle wall, the discharge point is always located at the edge of the current liquid level, avoiding the problem of viscous sauce accumulating and overflowing the filling tube 15, causing a sharp increase in pumping resistance, resulting in the actual discharge flow rate being less than the set flow rate and leading to insufficient filling volume. Before filling, the extension tube 42 is in the retracted state, completely retracted inside the fixed tube 41. At this time, the side wall of the extension tube 42 blocks the lower end of the filling tube 15, isolating the filling tube 15 from the internal cavity of the fixed tube 41 to prevent premature leakage of viscous sauce. When the filling tube 15 descends and reaches the neck of the bottle 12 and locks in the radial position, the electric push rod 3 5 immediately starts. Its drive end drives the extension tube 42 to extend smoothly and horizontally along the axis of the fixed tube 41. When the end of the extension tube 42 approaches the inner wall edge of the bottle 12, the electric push rod 3 5 stops, and the filling tube 15 is controlled by the motor 31 and the electric push rod 1. Driven by 2, it makes a spiral upward movement. During this process, the filling tube 15 opens to discharge, and the viscous sauce flows from the filling tube 15 into the connected fixed tube 41, and then flows out through the end of the extension tube 42. The viscous sauce flows to the edge of the inner wall of the bottle 12. When the extension tube 42 moves to the neck of the bottle 12 as the filling tube 15 spirals upward, the electric actuator 3 5 starts in the reverse direction, driving the extension tube 42 to retract smoothly along the axis of the fixed tube 41. At this time, the side wall of the extension tube 42 re-seals the lower end of the filling tube 15, and once again isolates the internal chamber of the filling tube 15 from the fixed tube 41. After retraction, the filling tube 15 continues to spiral upward at a uniform speed under the coordinated drive of the motor 31 and the electric push rod 2 until it reaches the preset height of the bottle 12 to complete the filling. After filling, the motor 31 and the electric push rod 2 reset in sequence, driving the filling tube 15 to rise to the initial high position. Then the clamping member 11 is released, the conveyor 1 sends the filled bottle 12 away, and all parts of the equipment return to the initial standby state, preparing for the next round of narrow-neck bottle filling cycle. In this invention, the electric push rod 35 drives the extension tube 42 to reciprocate linearly within the fixed tube 41, so that the filling tube 15... 5. Equipped with a "variable length" filling end, when the filling tube 15 enters the filling stage, the extension tube 42 extends horizontally in a controlled manner, extending the discharge point to the edge of the inner wall of the bottle. In conjunction with the spiral movement of the filling tube 15, it forces the viscous sauce to fill close to the bottle wall, avoiding the technical problem that the viscous sauce can only accumulate in the projected area of ​​the bottle neck and cannot spread to the edge. In addition, in the initial stage of filling, the extension tube 42 is in a retracted state, and its side wall actively seals the lower end of the filling tube 15, forming a physical barrier, which effectively prevents the viscous sauce from dripping and hanging due to gravity when not in operation, keeping the equipment clean. As the filling tube 15 drives the extension tube 42 to continuously revolve along the bottle wall and slowly spiral upward, the filling operation continues. When the bending component 6 at the end of the extension tube 42 moves to the constriction section of the bottle neck 12, the inner diameter of the bottle neck gradually decreases, which creates a radially inward squeezing force on the corrugated tube 61 protruding from the end of the extension tube 42 and the spring 62 sleeved on the outer periphery. The corrugated tube 61 adaptively bends and deforms with the constriction arc of the inner wall of the bottle neck, and the spring 62 on the outer periphery simultaneously undergoes elastic bending, conforming to the arc contour of the inner wall of the bottle neck, avoiding hard contact between rigid components and the bottle neck. During this adaptive bending process, the discharge channel inside the corrugated tube 61 remains unobstructed, and viscous sauce can still flow continuously out along the inner wall of the bottle neck through the end of the corrugated tube 61, maintaining the spiral filling trajectory. Interruption; Through the cooperation of the extension tube 42, the corrugated tube 61, and the spring 62, when the equipment is filling a bottle 12 with a slender neck, the corrugated tube 61 can flexibly bend and deform with the curvature of the bottle wall under the squeezing action of the narrowing inner diameter of the neck. With the synchronous elastic support of the outer peripheral spring 62, the filling end has the ability to "fit the bottle shape". This allows the filling tube 15 to smoothly transition from the bottle body to the neck area for continuous filling without interrupting the spiral trajectory. This effectively solves the technical problem that traditional rigid filling heads are prone to hard friction damage to the bottle wall when passing through the neck, or even equipment shutdown due to jamming. It not only ensures the full filling of viscous sauce in the neck area, but also significantly extends the service life and application range of the filling equipment.
