Description

Technical Field

[0001] This utility model belongs to the field of filling technology, specifically referring to a filling machine feeding mechanism. Background Technology

[0002] A filling machine is an automated machine that automatically and accurately dispenses liquids, pastes, powders, and other products into containers (such as bottles, cans, bags, and barrels). It is an indispensable core piece of equipment on production lines in industries such as food, beverage, daily chemicals, pharmaceuticals, and chemicals.

[0003] When filling liquid raw materials, empty bottles are moved one by one to the bottom of the discharge pipe by a conveyor belt for filling. However, the step delivery method can cause problems such as conveyor belt slippage, stepper motor step loss, and uneven bottle support spacing, which can lead to the bottles shifting at the filling station. This can result in misalignment between the discharge port and the bottle mouth, and leakage or dripping can easily occur at the discharge port after filling stops.

[0004] Therefore, there is an urgent need for a filling machine feeding mechanism to solve the above problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a solution that at least partially solves the problems mentioned in the background art.

[0006] The technical solution adopted by this utility model is as follows: A filling machine feeding mechanism is proposed, including: a feeding part, including a discharge pipe, a lifting feeding pipe is inserted into the bottom of the discharge pipe, a connecting pipe is fixedly connected to the bottom of the lifting feeding pipe, the diameter of the connecting pipe is smaller than that of the lifting feeding pipe, and a retaining ring is sleeved on the bottom of the lifting feeding pipe; a feeding nozzle assembly, including a feeding nozzle fixedly connected to the bottom of the connecting pipe, a sealing head is sleeved on the connecting pipe, a plurality of evenly distributed feeding holes are opened on the side wall of the feeding nozzle, the feeding holes are closed after the sealing head is sleeved on the feeding nozzle, and a conical guide part is formed at the bottom of the sealing head; a reset component, including a reset spring sleeved on the connecting pipe, the reset spring being located between the feeding nozzle and the retaining ring.

[0007] Furthermore, the discharge hole includes several evenly distributed circular holes formed on the side wall of the discharge nozzle, the inner diameter of which gradually decreases from top to bottom.

[0008] Furthermore, the discharge hole includes several inverted trapezoidal holes evenly distributed on the side wall of the discharge nozzle, and the internal width of the inverted trapezoidal holes gradually decreases from top to bottom.

[0009] Furthermore, the outer top edge of the sealing head is fixedly connected with several evenly distributed guide rods, and the surface of the retaining ring is provided with several evenly distributed limiting holes, and the guide rods are inserted into the limiting holes.

[0010] Furthermore, the filling machine's feeding mechanism also includes a frame, with a liquid storage tank fixedly connected to the top of the frame, and the top of the discharge pipe fixedly connected to the bottom of the frame, with the discharge pipe and the liquid storage tank communicating with each other.

[0011] Furthermore, an adjusting cylinder is fixedly connected to the bottom of the frame, and connecting plates are fixedly connected to both sides of the lifting discharge pipe. The telescopic end of the adjusting cylinder at the bottom is fixedly connected to the connecting plate. Beneficial effects

[0012] The conical guide at the bottom of the sealing head guides the bottle mouth directly below the dispensing nozzle before filling, facilitating alignment between the nozzle and the bottle mouth and preventing leakage during filling.

[0018] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0020] As mentioned above, in the prior art, the bottle may shift at the filling station, resulting in misalignment between the outlet and the bottle mouth. Furthermore, after filling stops, leakage or dripping may occur at the outlet.

[0021] To address this, the present invention provides a feeding mechanism for a filling machine, which guides the bottle mouth to directly below the dispensing nozzle before filling via the conical guide 5 at the bottom of the sealing head 202. This facilitates alignment between the filling nozzle and the bottle mouth, preventing leakage during filling. The dispensing hole 203 gradually increases in size from bottom to top along the direction of movement of the sealing head 202, reducing the gradient of the orifice diameter change when the sealing head 202 moves, thus minimizing the vibration caused to the dispensing section 1 when the dispensing hole 203 is opened or closed.

[0022] like Figures 1-4 As shown in the figure, this utility model provides a feeding mechanism, particularly a feeding mechanism for a filling machine, including a discharge section 1, a discharge nozzle assembly 2, a reset component 3, a frame 11, a liquid storage tank 12, an adjusting cylinder 13, and a connecting plate 14. The discharge section 1 includes a discharge pipe 101 fixedly connected to the bottom of the frame 11. A vertically movable lifting discharge pipe 102 is inserted inside the discharge pipe 101. The bottom of the lifting discharge pipe 102 gradually narrows inwards. A connecting pipe 103 is fixedly connected to the bottom of the lifting discharge pipe 102, and a retaining ring 4 is fitted onto the bottom of the lifting discharge pipe 102. The discharge nozzle assembly 2 includes a discharge nozzle 201 fixedly connected to the bottom of the connecting pipe 103. The outer diameter of the discharge nozzle 201 is slightly larger than that of the connecting pipe 103. A sealing head 202 is also fitted onto the connecting pipe 103. When the sealing head 202 moves to the lowest end of the connecting pipe 103, it covers and encloses the discharge nozzle 201. Several evenly distributed discharge holes 203 are opened on the side wall of the discharge nozzle 201. The discharge holes 203 discharge material from the side. The discharge holes 203 may include several evenly distributed round holes 7, such as... Figure 2 As shown, the inner diameter of the round hole 7 gradually decreases from top to bottom along the axial direction of the connecting pipe 103. This allows the sealing head 202 to be squeezed upward by the bottle mouth after it comes into contact with the bottle mouth, and the bottom of the discharge nozzle 201 to enter the inside of the bottle first, filling and spraying the liquid material from the side. The liquid material flows downward from the inner wall of the bottle, slowly completing the filling of the bottle.

[0023] The discharge nozzle 201 gradually emerges from bottom to top, and the diameter of the discharge hole 203 gradually increases, reducing sudden changes in the discharge volume and minimizing the gradient of discharge volume variation. Simultaneously, after feeding is complete, the reset member 3 on the connecting pipe 103 pushes the sealing head 202 downwards, blocking the discharge nozzle 201. The sealing head 202 moves slowly downwards, and the overall diameter of the discharge hole 203 gradually decreases, reducing vibrations to the connecting pipe 103 when the sealing head 202 closes the discharge nozzle 201. At the bottom of the sealing head 202, there is a conical opening that gradually narrows from bottom to top, guiding the sealing head 202 as it blocks the bottle opening. The bottom of the sealing head 202 forms a guide section 5.

[0024] The reset component 3 on the connecting pipe 103 includes a reset spring 6 sleeved on the connecting pipe 103. The reset spring 6 is located between the sealing head 202 and the retaining ring 4 connected to the bottom of the lifting discharge pipe 102, pressing the sealing head 202 downward to maintain the sealing head 202 blocking the discharge nozzle 201. The discharge nozzle 201 obstructs the sealing head 202, preventing the sealing head 202 from detaching from the connecting pipe 103. Several evenly distributed guide rods 9 are fixedly connected to the edge of the top of the sealing head 202. Several evenly distributed limiting holes 10 are opened on the retaining ring 4. The guide rods 9 are inserted into the limiting holes 10 to guide the lifting and lowering of the sealing head 202. In order to lift the lifting discharge pipe 102, connecting plates 14 are fixedly connected to both sides of the outside of the lifting discharge pipe 102, and adjusting cylinders 13 are fixedly connected to both sides of the bottom of the frame 11. The output end of the bottom of the adjusting cylinder 13 is fixedly connected to one end of the lifting discharge pipe 102 connected to the connecting plate 14.

[0025] During bottle filling, the lifting discharge pipe 102 descends, and the guide part 5 at the bottom of the sealing head 202 fits onto the bottle mouth, guiding the discharge nozzle 201 into the bottle body. The discharge hole 203 on the side wall of the discharge nozzle 201 flows downward from the inner wall of the bottle until the specified liquid is injected into the bottle. After the discharge nozzle 201 is pulled out from the bottle mouth, the sealing head 202 covers and blocks the discharge nozzle 201 to prevent further leakage after the discharge nozzle 201 has finished dispensing, ensuring that the discharge nozzle 201 is aligned with the bottle mouth and improving production capacity.
