A filling head for a bottled water filling machine

Abstract

This utility model discloses a filling head for a bottled water filling machine, including a filling head body, a filling tube, and an elastic sealing device. By setting an elastic sealing device on the surface of the filling tube, the cap on the surface of the filling tube will seal the bottle opening during the filling process, preventing liquid from splashing out. Simultaneously, the elastic force provided by the spring will press the pressure sleeve against the bottle neck surface, thus holding and fixing the bottle body. Furthermore, the pressure sleeve can be clamped to the bottle body surface by a bracket, further securing the bottle body and preventing it from tilting or tipping over, ensuring stability during the filling process. After filling, the filling tube is lifted upwards from the bottle to return to its original position. During this process, the cap will still be pressed against the bottle opening under the force of the spring, preventing the filling tube from carrying out liquid from the bottle and effectively reducing on-site leakage and pollution.

Description

Technical Field

[0001] This utility model relates to the field of filling head technology, specifically a filling head for a bottled water filling machine. Background Technology

[0002] Bottled water filling machines are automated equipment used for the industrial production of bottled water. They can quantitatively fill liquid into bottles and complete subsequent processes such as sealing and labeling. The filling head is the core functional component of the filling machine, responsible for the precise injection of liquid.

[0003] Existing patent application number: 201720387816.3. A bottled water filling head includes a metal insert, a first tube body disposed below the insert, a second tube body disposed below the first tube body, and a tapered nozzle with a gradually decreasing outer diameter disposed below the second tube body; the outer surface of the insert is smooth, and an external thread is provided in the middle part of the outer surface; a baffle is provided between the insert and the first tube body; the outer periphery of the first tube body is tapered, and a first vent groove is provided on the outer periphery of the first tube body; a limiting retaining ring is provided at the bottom of the outer surface of the second tube body; and a ring of evenly arranged square protrusions is provided on the surface of the nozzle, with a second vent groove disposed between the protrusions.

[0004] The aforementioned patent describes a filling head structure. Existing filling heads typically employ a slender tube structure to better extend into the bottle for filling. After filling, since the bottle is almost full, the filling head may carry out some liquid when it is lifted upwards, causing on-site contamination. Furthermore, during the filling process, empty bottles are easily impacted by the liquid injection from the filling head, leading to bottle instability and affecting filling stability. Therefore, we propose a filling head for bottled water filling machines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a filling head for a bottled water filling machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a filling head for a bottled water filling machine, comprising a filling head body, a filling tube, and an elastic sealing device. The filling tube is connected and installed at the bottom end of the filling head body. An elastic sealing device is provided on the surface of the filling tube. The elastic sealing device includes an upper limit ring, a cap, a spring, a pressure sleeve, a lower limit ring, and a sliding adjustment mechanism. An upper limit ring is sleeved on the upper end of the filling tube surface. A cap is slidably sleeved on the surface of the filling tube. The upper limit ring is glued to the top end of the spring. The cap is glued to the bottom end of the spring. The spring is sleeved on the outside of the filling tube. The bottom of the cap is glued to the pressure sleeve, and the cap and the pressure sleeve are internally connected. A lower limit ring is sleeved and fixed on the lower end of the filling tube surface. The cap is installed between the upper limit ring and the lower limit ring. A sliding adjustment mechanism is provided on the top of the upper limit ring.

[0007] Preferably, the pressure sleeve adopts a tapered sleeve structure.

[0008] Preferably, the bottom edge of the pressure sleeve is integrally provided with a bracket, the total number of brackets is not less than 3 sets, and all brackets are equidistantly distributed along the bottom edge of the pressure sleeve.

[0009] Preferably, the lower limiting ring and the filling tube are connected in a detachable manner.

[0010] Preferably, the cap and the pressure sleeve are made of lightweight plastic material.

[0011] Preferably, the sliding adjustment mechanism includes a locking groove, a sliding sleeve, and a positioning bolt. The locking groove is longitudinally formed on the surface of the filling tube. The upper limit ring is integrally connected to the top of the sliding sleeve. The sliding sleeve and the upper limit ring are internally connected. The upper limit ring is slidably sleeved with the surface of the filling tube by means of the sliding sleeve. A positioning bolt is screwed into the screw hole on the side of the sliding sleeve. The positioning bolt and the locking groove are located in the same direction. The positioning bolt is screwed into the inside of the sliding sleeve and abuts against the inner wall of the locking groove for fixation.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features an elastic sealing device on the surface of the filling tube. As the filling tube extends into the bottle, the cap on the tube surface seals the bottle opening, preventing liquid from splashing out during filling. Simultaneously, the elastic force provided by the spring presses the pressure sleeve against the bottle neck, thus holding and fixing the bottle. Furthermore, the pressure sleeve can be clamped onto the bottle surface by a bracket, further securing the bottle and preventing it from tilting or tipping over, ensuring stability during the filling process. After filling, the filling tube is lifted back from the bottle, and during this process, the cap remains pressed against the bottle opening by the spring force, preventing the filling tube from carrying out liquid and effectively reducing on-site leakage and pollution.

[0014] This invention features a sliding adjustment mechanism at the top of the upper limit ring. By loosening the positioning bolts to allow the sliding sleeve to slide freely, the height of the upper limit ring on the filling tube surface can be adjusted. The smaller the distance between the upper and lower limit rings, the higher the compression of the spring and the greater the elastic force provided. This allows for specific adjustments based on the bottle height, making it highly adaptable. Attached Figure Description

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 This utility model provides a filling head for a bottled water filling machine, including a filling head body 1, a filling tube 2 and an elastic sealing device 3. The bottom end of the filling head body 1 is connected to the filling tube 2, and the surface of the filling tube 2 is provided with the elastic sealing device 3.

[0023] Please see Figure 2 , Figure 4 and Figure 5This utility model provides a filling head for a bottled water filling machine. The elastic sealing device 3 includes an upper limit ring 31, a cap 32, a spring 33, a pressure sleeve 34, a lower limit ring 35, and a sliding adjustment mechanism 36. The upper limit ring 31 is sleeved on the upper surface of the filling tube 2. The cap 32 is slidably sleeved on the surface of the filling tube 2. The upper limit ring 31 is glued to the top of the spring 33, and the cap 32 is glued to the bottom of the spring 33. The spring 33 is sleeved on the outside of the filling tube 2. The bottom of the cap 32 is glued to the pressure sleeve 34, and the cap 32 and the pressure sleeve 34 are internally connected. The lower limit ring 35 is sleeved and fixed on the lower end of the surface of the filling tube 2. The cap 32 is installed between the upper limit ring 31 and the lower limit ring 35. The lower limit ring 35 can limit the minimum height of the cap 32 and prevent the cap 32 from sliding off the surface of the filling tube 2. The upper limit ring 31 is provided with a sliding adjustment mechanism 36.

[0024] To further explain, the pressure sleeve 34 adopts a conical sleeve structure, which allows the pressure sleeve 34 to better fit and press against the surface of the conical bottle neck, improving the pressure holding stability of the bottle body.

[0025] To further explain, the bottom edge of the compression sleeve 34 is integrally provided with a bracket 341. The total number of brackets 341 is no less than 3 sets. All the brackets 341 are equidistantly distributed along the bottom edge of the compression sleeve 34. The compression sleeve 34 can be clamped to the surface of the bottle through the brackets 341, further securing the bottle body and preventing it from tilting or tipping over due to force, thus ensuring the stability of the filling process.

[0026] To further explain, the lower limit ring 35 is detachably connected to the filling tube 2, which allows the components of the elastic sealing device 3 and the filling tube 2 to be disassembled and replaced, facilitating the maintenance of parts.

[0027] To further explain, the cap 32 and the pressure sleeve 34 are made of lightweight plastic to meet the requirements of weight reduction.

[0028] Specifically, by setting an elastic sealing device 3 on the surface of the filling tube 2, during the process of the filling head body 1 extending the filling tube 2 into the bottle, the cap 32 on the surface of the filling tube 2 will close the bottle mouth to prevent the liquid inside the bottle from splashing out during the filling process. At the same time, as the filling tube 2 is gradually extended into the bottle, the spring 33 will be compressed synchronously under force. The elastic force provided by the spring 33 will press the pressure sleeve 34 against the bottle neck surface, thereby pressing and fixing the bottle body. In addition, the pressure sleeve 34 can be clamped to the bottle body surface through the bracket 341 to further secure the bottle body, prevent it from tilting or tipping under force, and ensure the stability of the filling process.

[0029] After filling is completed, the filling tube 2 is lifted up from inside the bottle and reset. During this process, the cap 32 will still be pressed tightly at the bottle mouth by the force of the spring 33 to prevent the filling tube 2 from carrying out the liquid in the bottle, effectively reducing on-site dripping and pollution.

[0030] Please see Figure 3This utility model provides a filling head for a bottled water filling machine. The sliding adjustment mechanism 36 includes a locking groove 361, a sliding sleeve 362, and a positioning bolt 363. The filling tube 2 has a locking groove 361 longitudinally opened on its surface. The upper limit ring 31 is integrally connected to the top of the sliding sleeve 362. The sliding sleeve 362 and the upper limit ring 31 are interconnected. The upper limit ring 31 is slidably sleeved with the surface of the filling tube 2 by means of the sliding sleeve 362. The positioning bolt 363 is screwed into the screw hole on the side of the sliding sleeve 362. The positioning bolt 363 and the locking groove 361 are located in the same direction. The positioning bolt 363 is screwed into the sliding sleeve 362 and abuts against the inner wall of the locking groove 361 to fix it, thereby locking the upper limit ring 31 at the current height.

[0031] Specifically, by setting a sliding adjustment mechanism 36 at the top of the upper limit ring 31, when it is necessary to adjust the elasticity of the spring 33, first loosen the positioning bolt 363 to allow the sliding sleeve 362 to return to free sliding. Then, the sliding sleeve 362 can be moved to adjust the height position of the upper limit ring 31 on the surface of the filling tube 2. The smaller the distance between the upper limit ring 31 and the lower limit ring 35, the higher the compression degree of the spring 33 and the greater the elasticity provided. This allows for specific adjustments based on the height of the bottle, making it highly applicable. Finally, tightening the positioning bolt 363 will lock the upper limit ring 31 at the current height to complete the adjustment.
