Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically to an adjustable filling machine. Background Technology

[0002] Filling machines are a small category of packaging machines. From the perspective of material packaging, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. From the perspective of automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines. Recently, with the implementation of QS certification for food products, edible oil manufacturers have begun to focus on product quality and packaging, thus highlighting the importance of oil filling machines within the filling machine category.

[0003] Patent CN221458151 U discloses a hydrogen peroxide filling machine, comprising a base, a support box, a control panel, a filling device, a filling pipe, a connecting pipe, a fixing rod, a servo motor, and a transmission adjustment mechanism. The top of the base is fixedly connected to the bottom of the support box, and the left side of the control panel is fixedly connected to the right side of the support box. The filling device is located on the front side of the support box, with its bottom fixedly connected to the top of the filling pipe. The connecting pipe is located on the rear side of the support box and is connected to the filling device. The fixing rod is located on the right side of the support box, and the right side of the support box is fixedly connected to the servo motor. This invention solves the problem that existing hydrogen peroxide filling machines cannot adjust the filling volume according to the height of the hydrogen peroxide storage tank, making it cumbersome to fill hydrogen peroxide storage tanks of different heights, thus inconvenient for users.

[0004] However, in this prior art, although the height of the filling head can be adjusted according to the height of the bottle, the height of the bottle positioning mechanism cannot be adjusted by only adjusting the height of the filling head. When filling excessively tall bottles, the bottles may become unstable and may tip over.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable filling machine that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] An adjustable filling machine includes: a machine base; an upper support plate and a lower support plate movably mounted on the machine base; a filling assembly disposed on the upper support plate; a clamping assembly disposed on the lower support plate for clamping bottles; and an adjusting assembly for adjusting the filling height according to the height of the filling bottle.

[0009] The filling assembly includes: a filling head; a lifting plate fixedly installed with the filling head; and an electric cylinder that drives the lifting plate to move up and down, wherein the electric cylinder is fixedly installed on the upper support plate.

[0010] The clamping assembly includes: clamping plates symmetrically arranged on the lower support plate; a movable rod that guides the movement of the clamping plates and moves through the lower support plate; a hinge rod hinged to the clamping plate; a movable sleeve hinged to one end of the hinge rod; a guide rod that guides the movement of the movable sleeve; a spring that resets the guide rod; and extrusion cylinders fixedly installed at both ends of the lifting plate, with the extrusion cylinders located directly above the adjacent guide rods.

[0011] Furthermore, guide columns are symmetrically fixedly installed on the top of the lifting plate, and the guide columns extend through to the top of the upper support plate.

[0012] Furthermore, one side of the guide rod is designed to be arc-shaped.

[0013] Furthermore, the adjustment assembly includes: a worm gear; a worm wheel meshing with the worm gear; a positioning frame supporting the worm wheel, and the positioning frame is fixedly mounted on the machine base; a threaded rod fixedly connected to both ends of the worm gear, and one end of the threaded rod is rotatably mounted on the machine base, the threaded rod being threadedly installed with the adjacent upper support plate and the adjacent lower support plate.

[0014] Furthermore, sliders are fixedly installed on both sides of the upper support plate and the lower support plate, and symmetrical grooves are provided on both sides of the machine base to cooperate with the sliders on both sides of the upper support plate and the lower support plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: when the height of the filling head needs to be adjusted according to the height of the filling bottle, the adjustment component is set so that the clamping plate can always clamp the middle of the bottle, preventing the bottle from becoming unstable when filling excessively tall bottles.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 4 As shown, the adjustable filling machine of this utility model includes: a machine base 1; an upper support plate 2 and a lower support plate 3 movably mounted on the machine base 1; a filling assembly 4 disposed on the upper support plate 2; a clamping assembly 5 disposed on the lower support plate 3 for clamping the bottle; and an adjusting assembly 6 for adjusting the filling height according to the height of the filling bottle.

[0025] The filling assembly 4 includes: a filling head 401; a lifting plate 402 fixedly installed with the filling head 401; an electric cylinder 403 that drives the lifting plate 402 to move up and down, and the electric cylinder 403 is fixedly installed on the upper support plate 2; the upper support plate 2 has an opening so that it is not interfered with when the filling head 401 moves up.

[0026] The clamping assembly 5 includes: clamping plates 501 symmetrically arranged on the lower support plate 3; a movable rod 502 that guides the movement of the clamping plates 501 and movably passes through the lower support plate 3; a hinge rod 503 hingedly mounted on the clamping plates 501; a movable sleeve 504 hingedly mounted to one end of the hinge rod 503; a guide rod 505 that guides the movement of the movable sleeve 504; and a spring 506 that resets the guide rod 505. It should be noted that the spring 506 is fitted onto the guide rod 505, and one end of the spring 506 is connected to the movable sleeve. The bottom of the sleeve 504 is fixedly installed, and the other end of the spring 506 is fixedly installed on the lower support plate 3. When the movable sleeve 504 is released from pressing the extrusion cylinder 507, the spring 506 is elastically reset after being subjected to force, pushing the movable sleeve 504 to move upward. The extrusion cylinder 507 is fixedly installed at both ends of the lifting plate 402, and the extrusion cylinder 507 is located directly above the adjacent guide rod 505. It should be noted that the internal diameter of the extrusion cylinder 507 is larger than the cross-sectional diameter of the guide rod 505. When the extrusion cylinder 507 descends, the guide rod 505 can be inserted into the extrusion cylinder 507.

[0027] During bottle filling, the bottle is placed between two clamping plates 501. When the output end of the electric cylinder 403 pushes the filling head 401 below the lifting plate 402 to move towards the bottle, the extrusion cylinders 507 on both sides of the bottom of the lifting plate 402 press against the movable sleeves 504 fitted on the corresponding guide rods 505. At this time, the movable sleeves 504 move down, and the movable sleeves 504 drive the hinged hinge rods 503 to deflect, causing the hinge rods 503 to push the clamping plates 501 closer to one side of the bottle. After the filling head 401 descends to the position, the two symmetrical clamping plates 501 complete the clamping and fixing of the middle part of the bottle, thereby realizing the automatic clamping of the bottle and further improving the filling efficiency.

[0028] It should be added that guide columns are symmetrically fixedly installed on the top of the lifting plate 402, and the guide columns extend through to the top of the upper support plate 2; the setting of the guide columns improves the stability of the movement of the lifting plate 402.

[0029] It should be added that one side of the guide rod 505 is curved; by making one side of the guide rod 505 curved, the contact area with the bottle is increased when clamping the bottle being filled, thus improving the stability of the bottle clamping.

[0030] The adjusting assembly 6 includes: a worm gear 601; a worm wheel 602 meshing with the worm gear 601; a positioning frame 603 supporting the worm wheel 602, and the positioning frame 603 is fixedly mounted on the machine base 1; and a threaded rod 6011 fixedly connected to both ends of the worm gear 601, with one end of the threaded rod 6011 rotatably mounted on the machine base 1. The threaded rod 6011 is threadedly mounted to the adjacent upper support plate 2 and the adjacent lower support plate 3. It should be noted that one end of the threaded rod 6011 is rotatably mounted to the machine base 1 via a bearing, and the helical directions of the two threaded rods 6011 are the same.

[0031] When adjustment is needed based on the height of the filling bottle, the worm gear 602 is manually rotated to mesh with the worm 601. At this time, the threaded rods 6011 at both ends of the worm 601 rotate, thereby driving the upper support plate 2 and the lower support plate 3 on the two threaded rods 6011 to rise and fall synchronously. This allows the height of the filling head 401 to be adjusted simultaneously with the height of the clamping plate 501, ensuring that the clamping plate 501 can always clamp the middle of the bottle. This prevents instability caused by excessive filling if the bottle is too high during filling, as this would increase the amount of liquid being filled. This is especially problematic for bottles with special treatments where the bottom is not flat, where only the bottom is clamped, leading to instability due to excessive filling height.

[0032] It's important to note that the main reason manually turning the worm gear can drive the worm is due to the helical effect between the worm gear and the worm. When the worm gear is manually turned, the helical teeth on the worm gear wind forward along the helix of the worm. During this process, the tip of each tooth always contacts the generatrix of the worm, transmitting power through the friction between the worm and the worm gear, thus achieving rotational transmission.

[0033] It should be added that sliders are fixedly installed on both sides of the upper support plate 2 and the lower support plate 3, and the machine base 1 has symmetrical grooves on both sides that cooperate with the sliders on both sides of the upper support plate 2 and the lower support plate 3; by sliding the upper support plate 2 and the lower support plate 3 on the machine base 1, the stability of the movement of the upper support plate 2 and the lower support plate 3 is further improved.

[0034] Working principle: When the power is turned on, during bottle filling, the bottle is placed between two clamping plates 501. When the output end of the electric cylinder 403 pushes the filling head 401 below the lifting plate 402 to move towards the bottle, the extrusion cylinders 507 on both sides of the bottom of the lifting plate 402 press against the movable sleeves 504 fitted on the corresponding guide rods 505. At this time, the movable sleeves 504 move downward, causing the hinged rods 503 to deflect, pushing the clamping plates 501 closer to one side of the bottle. After the head 401 descends to its position, the two symmetrical clamping plates 501 clamp and fix the middle part of the bottle. When it is necessary to adjust the height according to the filling bottle, the worm gear 602 is manually rotated to mesh with the worm 601. At this time, the threaded rods 6011 at the upper and lower ends of the worm 601 rotate, thereby driving the upper support plate 2 and the lower support plate 3 on the two threaded rods 6011 to rise and fall synchronously. This allows the height of the clamping plate 501 to be adjusted accordingly while the height of the filling head 401 is adjusted.
