Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cleaning agent filling technology, specifically relating to a cleaning agent filling piston rod balancing device. Background Technology
[0002] Currently, cleaning agent filling equipment typically employs a multi-bottle simultaneous filling method. To ensure simultaneous and equal filling, multiple filling tubes are used, each corresponding to a separate metering cylinder. A piston rod slides inside the metering cylinder, and quantitative filling is achieved by controlling the movement length of the piston rod. However, during simultaneous filling of multiple bottles, the varying resistance of each piston rod can lead to uneven movement during synchronous filling. This results in different filling speeds across the metering cylinders, requiring the filling operation to wait for the last metering cylinder to finish. Furthermore, the asynchrony among the multiple metering cylinders can cause incomplete filling of some cleaning agents, necessitating manual replenishment and impacting the overall filling efficiency. Utility Model Content
[0003] This utility model provides a cleaning agent filling piston rod balancing device, which aims to solve the problem of uneven filling that easily occurs in the use of existing multi-tube filling equipment, causing rework and affecting the filling efficiency of cleaning agents.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a cleaning agent filling piston rod balancing device, comprising:
[0005] Filling rack;
[0006] There are multiple metering cylinders, which are arranged in parallel with intervals between them; the arrangement direction of the multiple metering cylinders is defined as a first direction, and a piston rod is slidably arranged inside each metering cylinder, and the sliding direction of the piston rod is defined as a second direction.
[0007] A guide sleeve is installed between two adjacent piston rods, and the guide sleeve is slidably disposed on the filling frame along a second direction;
[0008] A pusher, mounted on the filling rack, is used to push the piston rod to move in the second direction;
[0009] A connecting assembly is disposed between the guide sleeve and the piston rod for connecting the guide sleeve between two adjacent piston rods.
[0010] In one possible implementation, the connection component includes:
[0011] A connecting sleeve is fitted between the drive end of the pusher and the piston rod;
[0012] The connecting sleeve has a retaining plate at both ends, and the retaining plate is fixedly installed on the adjacent guide sleeve.
[0013] Fasteners, threadedly connected to the drive end of the pusher or the piston rod, are used to secure the clamping plate to the end of the connecting sleeve.
[0014] In one possible implementation, the two ends of the connecting sleeve are respectively provided with threaded holes for threaded connection with the piston rod and the drive end of the pusher, and the threaded holes at both ends of the connecting sleeve rotate in opposite directions.
[0015] In one possible implementation, the two clamping plates located on the edge of the piston rod are fixed to the same guide sleeve.
[0016] In one possible implementation, the two clamping plates located on the piston rod in the middle are respectively fixedly mounted on two adjacent guide sleeves.
[0017] In one possible implementation, both ends of the connecting sleeve are threadedly connected to a clamping member, and the clamping plate is held between the clamping member and the fastener.
[0018] In one possible implementation, a guide post is fixedly installed between two adjacent piston rods, and the guide sleeve is slidably disposed on the guide post.
[0019] In one possible implementation, the sidewall of the connecting sleeve is provided with an anti-rotation edge to facilitate rotation of the connecting sleeve.
[0020] The solution shown in this application, compared with the prior art, features a filling rack with multiple metering cylinders spaced apart along a first direction, each with its outlet connected to a filling tube.

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] Please refer to the following: Figure 1 and Figure 2 The present invention provides a cleaning agent filling piston rod balancing device. The cleaning agent filling piston rod balancing device includes a filling frame 1, a metering cylinder 2, a guide sleeve 4, a pushing component 5, and a connecting assembly 6. Multiple metering cylinders 2 are arranged in parallel at intervals. The arrangement direction of the multiple metering cylinders 2 is defined as a first direction. A piston rod 3 is slidably disposed inside each metering cylinder 2, and the sliding direction of the piston rod 3 is defined as a second direction. The guide sleeve 4 is installed between two adjacent piston rods 3 and is slidably disposed on the filling frame 1 along the second direction. The pushing component 5 is installed on the filling frame 1 and is used to push the piston rod 3 to move along the second direction. The connecting assembly 6 is disposed between the guide sleeve 4 and the piston rod 3 and is used to connect the guide sleeve 4 to two adjacent piston rods 3.
[0027] The cleaning agent filling piston rod balancing device provided in this embodiment, compared with the prior art, is equipped with a filling frame 1, on which multiple metering cylinders 2 are installed. These metering cylinders 2 are spaced apart along a first direction, and their outlet ends are connected to the filling tubes. A piston rod 3 is slidably installed inside each metering cylinder 2. The reciprocating movement of the piston rod 3 within the metering cylinder 2 completes the cleaning agent suction and discharge operations. In this application, a guide sleeve 4 is slidably installed on the filling frame 1 along a second direction. The guide sleeve 4 is connected between two adjacent piston rods 3 via a connecting assembly 6. This allows multiple pushing members 5 to move the piston rods 3 synchronously, ensuring that the displacements of the piston rods 3 are the same. This guarantees that multiple filling tubes can be filled synchronously with the same filling volume, ensuring uniform and stable output during the filling process, avoiding rework, and improving filling efficiency.
[0028] Specifically, in this embodiment, multiple metering cylinders 2 are of the same size and are arranged vertically in the second direction. An outlet pipe and an inlet pipe are connected to the bottom of each metering cylinder 2. Both the outlet and inlet pipes are equipped with one-way valves. The outlet pipe is connected to a filling pipe, and the inlet pipe is used to connect to a container holding the cleaning agent. When the piston rod 3 moves upward, the cleaning agent flows into the metering cylinder 2 through the inlet pipe; when the piston rod 3 moves downward, the cleaning agent flows out through the outlet pipe.
[0029] In some embodiments, the connection component 6 described above may be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The connecting assembly 6 includes a connecting sleeve 61, a retaining plate 62, and a fastener 63. The connecting sleeve 61 is fitted between the driving end of the pusher 5 and the piston rod 3; both ends of the connecting sleeve 61 abut against the retaining plate 62, and the retaining plate 62 is fixedly installed on adjacent guide sleeves 4; the fastener 63 is threadedly connected to the driving end of the pusher 5 or the piston rod 3, used to fasten the retaining plate 62 to the end of the connecting sleeve 61. Retaining plates 62 are fixedly installed on both sides of the guide sleeve 4 along the first direction. The retaining plates 62 connect the connecting sleeves 61 located on both sides of the guide sleeve 4 together. The connecting sleeve 61 connects between the driving end of the pusher 5 and the piston rod 3, thus allowing the piston rods 3 on both sides of the guide sleeve 4 along the first direction to be connected to the guide sleeve 4 via the retaining plates 62. When multiple piston rods 3 move, synchronous movement of multiple piston rods 3 can be achieved through connection with the guide sleeve 4. Simultaneously, the structure is simple and facilitates connection between two adjacent piston rods 3.
[0030] Specifically, in this embodiment, a clearance groove is provided on the card plate 62 to avoid the driving end of the pusher 5 or the piston rod 3.
[0031] Specifically, in this embodiment, during installation, the retaining plate 62 on the guide sleeve 4 can be moved to the drive end of the pusher 5 and the piston rod 3 first, and then the guide sleeve 4 can be installed at the drive end and the piston rod 3. The retaining plate 62 is then limited between the fastener 63 and the guide sleeve 4 by the fastener 63. This allows the guide sleeve 4 to be limited between the two retaining plates 62. When the piston rod 3 moves up and down, it can be limited by the two retaining plates 62, causing the guide sleeve 4 to move up and down together.
[0032] In some embodiments, the connecting sleeve 61 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2The connecting sleeve 61 has threaded holes at both ends for threaded connection with the piston rod 3 and the drive end of the pusher 5, respectively, and the threaded holes at both ends of the connecting sleeve 61 rotate in opposite directions. The connecting sleeve 61 is connected to the drive end of the pusher 5 and the end of the piston rod 3 by threads. The distance between the piston rod 3 and the drive end of the pusher 5 can also be adjusted by rotating the connecting sleeve 61. It can realize the adjustment of the position of a single piston rod 3. During the initial debugging process, multiple piston rods 3 can be positioned at the same height by rotating the connecting sleeve 61. When the piston rod 3 moves to the lowest position, multiple piston rods 3 can move synchronously to the bottom of the metering cylinder 2, reducing the residue of cleaning agent inside the metering cylinder 2, facilitating later maintenance and cleaning, and also facilitating the filling of cleaning agent later.
[0033] In some embodiments, the guide sleeve 4 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 Two retaining plates 62 are fixed to the same guide sleeve 4 on the side piston rod 3. Two retaining plates 62 are fixedly installed on the side of the guide sleeve 4 near the outer piston rod 3, and these two retaining plates 62 are engaged with the upper and lower ends of the connecting sleeve 61 on the outermost piston rod 3. This allows the outermost piston rod 3 to move up and down together with the guide sleeve 4.
[0034] In some embodiments, the guide sleeve 4 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 Two retaining plates 62 are fixedly mounted on two adjacent guide sleeves 4 on the central piston rod 3. Both ends of the connecting sleeve 61 on the central piston rod 3 abut against retaining plates 62, and the retaining plates 62 at both ends of the connecting sleeve 61 are fixedly mounted on two adjacent guide sleeves 4. This allows multiple piston rods 3 to be connected one by one via the guide sleeves 4. During use, if it is necessary to reduce the number of through-tubes, the outermost pushing member 5 can be stopped individually, and the working state of the remaining piston rods 3 can be adjusted by adjusting the position of the guide sleeves 4. The working state of the piston rods 3 can be adjusted according to the actual working requirements on site.
[0035] In some embodiments, the connecting sleeve 61 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2Both ends of the connecting sleeve 61 are threadedly connected to a clamping member 64, and the clamping plate 62 is held between the clamping member 64 and the fastener 63. The connecting sleeve 61 also has a clamping member 64 threadedly connected to both ends. Both the clamping member 64 and the fastener 63 are nuts, and both ends of the connecting sleeve 61 have external threads for threaded connection with the clamping member 64. After the connecting sleeve 61 is installed between the two clamping plates 62, rotating the clamping member 64 allows it to abut against the clamping plate 62. Finally, rotating the fastener 63 presses the clamping plate 62 between the fastener 63 and the clamping member 64. This improves the stability of the connection between the connecting sleeve 61 and the two clamping plates 62. It also prevents the connecting sleeve 61 from moving relative to the clamping plates 62 during the up-and-down movement of the piston rod 3. This improves positional accuracy, thereby ensuring a stable output from the metering cylinder 2.
[0036] In some embodiments, the piston rod 3 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 A guide post 7 is fixedly installed between two adjacent piston rods 3, and the guide sleeve 4 is slidably mounted on the guide post 7. By setting the guide post 7, the stability of the guide sleeve 4 during the vertical movement can be effectively improved.
[0037] Specifically, in this embodiment, the two clamping plates 62 fixedly installed on the guide sleeve 4 are tightened and fixed to the connecting sleeve 61 by fasteners 63 and tightening members 64. Furthermore, the guidance of the guide post 7 improves the synchronicity of the connecting sleeves 61 on the multiple piston rods 3 during their up-and-down movement, thereby enhancing the synchronicity of the piston rods 3 during movement.
[0038] In some embodiments, the connecting sleeve 61 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The connecting sleeve 61 has an anti-rotation edge on its side wall to facilitate rotation. The anti-rotation edge on the outer side wall of the connecting sleeve 61 allows the operator to easily rotate the connecting sleeve 61 between the piston rod 3 and the drive end of the pusher 5 using tools, which facilitates adjustment of the initial height of the piston rod 3 during the debugging process.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
