Description

Technical Field

[0001] The utility model relates to the technical field of filling and sealing machines, in particular to a liquid injection regulating device for a filling and sealing machine. Background Art

[0002] Filling equipment is mainly a type of packaging machine. From the perspective of material packaging, it can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines; in terms of the degree of production automation, it can be divided into semi-automatic filling machines and fully automatic filling production lines.

[0003] The existing filling and sealing machine adjusts the liquid injection device. When filling, the filling machine uses the liquid injection device, that is, the liquid injection tube and the filling head, to push down and insert into the upper end of the bottle body under the action of the telescopic device, and then directly injects the solution. However, when the liquid injection device sprays liquid, the instantaneous liquid has a certain impact force and contacts with the bottom of the bottle, which may cause splashing, causing the solution to splash and scatter out of the bottle mouth, affecting the working environment and making the liquid injection work unstable.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a filling machine regulating liquid injection device is proposed. Utility Model Content

[0005] The utility model aims to provide a liquid injection regulating device for a filling machine to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, the upper end of the shift block slides through the movable frame, the shape of the movable frame is set to be a "丄" shape, and the upper surface of the rear side of the movable frame is provided with a through hole matching the positioning hole.

[0008] Preferably, the injection mechanism comprises an injection tube fixedly mounted at the front end of the extension rod, the upper end of the injection tube is connected to a feeding tube, and the lower end of the injection tube is fixedly provided with a conical filling head.

[0010] Preferably, the liquid injection mechanism further includes a sealing ring fixedly installed at the lower end of the guiding rod. A spring is sleeved on the upper surface of the sealing ring and fixedly installed outside the guiding rod, and the upper end of the spring is fixedly connected to the fixing plate.

[0011] Preferably, a convex block is fixedly arranged in the middle of the rear side of the movable frame, and an electric telescopic rod is fixedly installed on the upper surface of the convex block.

[0012] Preferably, a fitting is fixedly arranged on the surface of the outer sleeve of the electric telescopic rod, and the fitting can be installed on the filling machine by bolts.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the settings of the sliding block, the dial block, the positioning hole and the scale line, the present utility model drives the sliding block to move through the dial block, and the distance between the liquid injection mechanisms can be flexibly adjusted according to different interval distances to adapt to different filling requirements. At the same time, the adjusting position can be fixed by inserting a pin through the dial block into the positioning hole to prevent secondary sliding, improving the adjustment stability. By aligning with the scale line, it can be adjusted more precisely;

[0015] 2. Through the settings of the liquid injection mechanism, the liquid injection pipe, the feeding pipe, the filling head, the fixing plate, the guiding rod, the sealing ring and the spring, during the liquid injection operation, the liquid injection pipe and the filling head move downward, the filling head is inserted into the receiving bottle, and the material is transported through the feeding pipe for filling. During the downward movement, the sealing ring will fit on the bottle mouth. As the filling head and the liquid injection pipe continue to move downward, the sealing ring will push the guiding rod upward, thereby squeezing the spring to contract. The elastic force of the spring itself will push the sealing ring to closely adhere to the bottle mouth position. Cooperating with the conical filling head, it can seal the bottle mouth to prevent the solution material from spraying and splashing during filling, resulting in pollution of the working area, and greatly improving the stability of the filling operation.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 - 3 As shown, a liquid injection regulating device for a filling machine comprises a movable frame 1, a sliding block 2 is slidably provided on the inner surface of the movable frame 1, a shifting block 3 is fixedly installed on the upper surface of the sliding block 2, positioning holes 4 are evenly distributed on the rear side of the upper surface of the movable frame 1, scale lines 5 are provided on the front side of the upper surface of the movable frame 1, an extension rod 6 is fixedly installed on the front end of the sliding block 2, and a liquid injection mechanism 7 is provided on the front end of the extension rod 6.

[0022] Furthermore, the upper end of the shift block 3 slides through the movable frame 1 , the shape of the movable frame 1 is set to be a "丄" shape, and a through hole matching the positioning hole 4 is set on the upper rear surface of the movable frame 1 .

[0023] By adopting the above technical solution, the shifting block 3 drives the sliding block 2 to move, and the spacing between the injection mechanisms 7 can be flexibly adjusted according to different spacing distances to adapt to different filling requirements;

[0024] The adjustment position can be fixed by inserting the pin through the shift block 3 and into the positioning hole 4 to prevent secondary slippage;

[0025] Using the scale lines 5, more precise adjustments can be made.

[0026] Furthermore, the injection mechanism 7 includes an injection tube 701 fixedly installed at the front end of the extension rod 6 , the upper end of the injection tube 701 is connected to a feeding tube 702 , and the lower end of the injection tube 701 is fixedly provided with a conical filling head 703 .

[0027] By adopting the above technical solution, the liquid injection pipe 701 and the filling head 703 are moved downward, the filling head 703 is inserted into the receiving bottle, and the material is transported by the feeding pipe 702 to perform the filling work.

[0028] Furthermore, the liquid injection mechanism 7 also includes a fixing plate 704 fixedly arranged below the surface of the liquid injection tube 701 , and guide rods 705 are slidably arranged on the left and right sides of the surface of the fixing plate 704 .

[0029] Furthermore, the injection mechanism 7 also includes a sealing ring 706 fixedly installed at the lower end of the guide rod 705 , and the upper surface of the sealing ring 706 is sleeved on the outer side of the guide rod 705 and fixedly installed with a spring 707 , and the upper end of the spring 707 is fixedly connected to the fixing plate 704 .

[0030] By adopting the above technical solution, the sealing ring 706 will fit on the bottle mouth. As the filling head 703 and the liquid injection pipe 701 continuously move downward, the sealing ring 706 will push the guiding rod 705 upward, thereby squeezing the spring 707 to contract. The elastic force of the spring 707 itself will push the sealing ring 706 to closely adhere to the bottle mouth position. Cooperating with the conical filling head 703, it can seal and close the bottle mouth to prevent the solution material from spraying and splashing during filling.

Then, use the electric telescopic rod 9 to push the entire movable frame 1 downward, so that the liquid injection pipe 701 and the filling head 703 move downward, and the filling head 703 is inserted into the receiving bottle, and use the feed pipe 702 to transport the material for filling work. During the downward movement, the sealing ring 706 will fit on the bottle mouth. As the filling head 703 and the liquid injection pipe 701 continuously move downward, the sealing ring 706 will push the guiding rod 705 upward, thereby squeezing the spring 707 to contract. The elastic force of the spring 707 itself will push the sealing ring 706 to closely adhere to the bottle mouth position. Cooperating with the conical filling head 703, it can seal and close the bottle mouth to prevent the solution material from spraying and splashing during filling, resulting in pollution of the working area, and enabling the solution material to be stably filled. This is the working principle of this filling and sealing machine for adjusting the liquid injection device.
