Description

Technical Field

[0001] This utility model relates to the technical field of sealant filling equipment, and in particular to a filling device for polysulfide sealant. Background Technology

[0002] Polysulfide sealant is a high-viscosity sealing material widely used in construction, insulated glass, aerospace, and other fields. During production, polysulfide sealant needs to be precisely filled into specialized packaging containers for storage and transportation.

[0003] Existing automated filling equipment typically employs an assembly line operation method, including a tank conveying mechanism and a filling execution mechanism. To achieve accurate filling, the tank conveying mechanism needs to intermittently transport the tank to the filling station, and at the moment the tank stops, the filling execution mechanism performs the filling action, and after filling, it moves to the next station.

[0004] In existing technologies, the intermittent movement of the tank conveying mechanism and the lifting action of the filling actuator are typically controlled by two independent drive units, and then coordinated in sequence by a programmable controller and sensors. This approach not only results in complex equipment structure and high cost, but also a strong dependence on the electrical control system.

[0005] If the control signal is delayed or the program logic malfunctions, a timing misalignment can easily occur between the stopping of the tank conveying mechanism and the descent of the filling actuator, leading to sealant overflow, inaccurate filling volume, or disordered equipment operation. This non-mechanically forced synchronization structure makes it difficult to guarantee long-term, precise coordination between the two sets of intermittent movements during high-speed operation.

[0006] Therefore, this utility model proposes a filling device for polysulfide sealant to overcome the shortcomings of the prior art. Utility Model Content

[0007] In the existing technology, the filling device for polysulfide sealant usually requires two independent drive units to control the tank conveying mechanism and the filling execution mechanism, which results in complex equipment structure, high cost, and reliance on the electrical control system to coordinate the timing, which is prone to timing misalignment leading to filling failure. The present invention aims to provide a polysulfide sealant filling device with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a filling device for polysulfide sealant, including: a frame, a drive shaft, a driven shaft, a transmission belt, a filler, a storage tank, a delivery pipe, and a hose.

[0009] The device also includes a motor; a drive shaft; a driven pulley; a driving pin component; a rod; a connector; and an abutment block.

[0010] The drive shaft and driven shaft are rotatably connected to the frame, and a drive belt is fitted around the outer circumference of the drive shaft and driven shaft. The filling device is slidably connected to the frame and positioned above the drive belt. The storage tank is connected to the filling device via a delivery pipe and a hose.

[0011] Furthermore, the motor is fixedly connected to the frame. The drive shaft is connected to the output end of the motor. The driven grooved wheel is fixedly connected to the drive shaft. The driving pin component is fixedly connected to the drive shaft, and the driving pin component can periodically insert into the groove of the driven grooved wheel when the drive shaft rotates. The round rod is slidably connected to the frame, and the upper end of the round rod is fixedly connected to the filling device through a connector. The abutment block is fixedly connected to the drive shaft, and the outer circumference of the abutment block abuts against the bottom end of the round rod.

[0012] Preferably, a filling device for polysulfide sealant further includes an electric push rod and a leveler. The electric push rod is fixedly connected to the frame, and the push rod end of the electric push rod is fixedly connected to the leveler, which is located on the upstream side of the filling device.

[0013] Preferably, the conveyor belt carries the iron can, and the iron can is equipped with an inner liner bag. The bottom shape of the leveler is adapted to the opening of the iron can.

[0014] Preferably, a rotating block is also fixedly connected to the drive shaft.

[0015] Preferably, the filling device for polysulfide sealant further includes a limiting block. The limiting block is fixedly connected to the frame and positioned near the rotation path of the abutment block.

[0016] Preferably, the filling device for polysulfide sealant further includes a support plate. The support plate is fixedly connected to the frame, and one end of the driven shaft is rotatably connected to the support plate.

[0017] Preferably, the inlet of the filling machine is connected to the outlet of the hose, and the inlet of the hose is connected to the conveying pipe.

[0018] Preferably, the active pin component and the abutment block have a preset circumferential relative mounting position on the drive shaft.

[0019] This utility model has the following beneficial effects: 1. In this utility model, by setting a motor and a drive shaft, and coaxially fixing an active circular pin component and an abutment block on the drive shaft, the active circular pin component drives the transmission belt to achieve intermittent conveying, and the abutment block drives the filling device to achieve intermittent lifting and lowering. This solves the problem that the prior art usually requires two independent drive control systems for tank conveying and filling device lifting, which are difficult to synchronize accurately and have complex structures. It achieves the technical effect of using only a single power source to realize forced mechanical synchronization of two sets of intermittent actions, with coordinated and accurate actions, compact structure and high operational reliability.

[0020] 2. In this utility model, by setting an electric pusher and a leveler in front of the filling station, the inner liner bag inside the iron can is pre-leveled, which solves the problem that the inner liner bag is prone to wrinkling during the filling of polysulfide sealant, resulting in uneven filling, affecting product quality, or causing sealant leakage and corrosion of the iron can. It achieves the technical effect of ensuring the inner liner bag is flat, improving filling accuracy and consistency, and facilitating subsequent cleaning. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, 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 a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 5 This utility model provides a filling device for polysulfide sealant, which aims to solve the problems in the prior art where the tank conveying mechanism and the filling execution mechanism need to be driven independently and are difficult to synchronize accurately, as well as the problem that wrinkles in the inner liner bag affect the filling quality.

[0025] like Figure 1 As shown, the filling device for the polysulfide sealant includes a frame 1, a drive shaft 15 and a driven shaft 16. The drive shaft 15 and the driven shaft 16 are rotatably connected to the frame 1. A transmission belt 17 is sleeved on the outer periphery of the drive shaft 15 and the driven shaft 16. The transmission belt 17 is used to carry the iron can 20.

[0026] The device also includes a filling device 12, which is slidably connected to the frame 1 and positioned above the transmission belt 17, and a storage tank 13. The storage tank 13 is connected to the filling device 12 via a conveying pipe 14 and a hose 11. Specifically, the inlet of the filling device 12 is connected to the outlet of the hose 11, the inlet of the hose 11 is connected to the conveying pipe 14, and the conveying pipe 14 is connected to the storage tank 13.

[0027] The device also includes an electric push rod 18, which is fixedly connected to the frame 1. A leveler 19 is fixedly connected to the push rod end of the electric push rod 18. The leveler 19 is located on the upstream side of the filling device 12. An inner liner bag 21 is provided inside the iron can 20. The bottom shape of the leveler 19 is adapted to the opening of the iron can 20.

[0028] The device also includes a support plate 22, which is fixedly connected to the frame 1, and one end of the driven shaft 16 is rotatably connected to the support plate 22.

[0029] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the filling device for the polysulfide sealant also includes a motor 2, a drive shaft 3, an active round pin component 5, a driven grooved wheel 8, a round rod 9, and an abutment block 6. The drive shaft 3 simultaneously drives the active round pin component 5 and the abutment block 6 to realize the synchronous intermittent movement of the transmission belt 17 and the filling device 12.

[0030] Please refer to the following carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The core structure is described in detail below: Motor 2 is fixedly connected to frame 1, drive shaft 3 is connected to the output end of motor 2, and drive shaft 3 is rotatably connected to frame 1.

[0031] The core structure includes two synchronous transmission branches: the first transmission branch is used to drive the transmission belt 17. This branch includes a driven pulley 8 and a driving pin component 5. The driven pulley 8 is fixedly connected to the driving shaft 15, and the driving pin component 5 is fixedly connected to the drive shaft 3. When the drive shaft 3 rotates, the driving pin component 5 can periodically insert into the groove of the driven pulley 8 to drive the driven pulley 8 to rotate intermittently.

[0032] The second transmission branch is used to drive the filling device 12. This branch includes a round rod 9 and an abutment block 6. The round rod 9 is slidably connected to the frame 1. The upper end of the round rod 9 is fixedly connected to the filling device 12 through a connector 10. The abutment block 6 is fixedly connected to the drive shaft 3. The outer circumferential contour of the abutment block 6 abuts against the bottom end of the round rod 9. When the drive shaft 3 rotates, the outer circumferential contour of the abutment block 6 pushes the round rod 9 to slide up and down intermittently.

[0033] The active round pin component 5 and the abutment block 6 have a preset circumferential relative mounting position on the drive shaft 3. This preset circumferential relative mounting position ensures that when the active round pin component 5 drives the driven groove wheel 8 to rotate (i.e., the transmission belt 17 moves), the protruding surface of the abutment block 6 is pushing against the round rod 9 (i.e., the filling device 12 moves upward), and ensures that when the active round pin component 5 disengages from the driven groove wheel 8 (i.e., the transmission belt 17 stops), the non-protruding surface of the abutment block 6 rotates away from the round rod 9 (i.e., the filling device 12 resets and descends to perform filling).

[0034] A rotating block 4 is also fixedly connected to the drive shaft 3. The device also includes a limiting block 7, which is fixedly connected to the frame 1 and positioned near the rotation path of the abutment block 6.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to prevent wrinkles in the inner liner bag and ensure filling quality, please refer to... Figure 1 , Figure 3 and Figure 5 The device also includes an electric push rod 18, which is fixedly connected to the frame 1. A leveler 19 is fixedly connected to the push rod end of the electric push rod 18. The leveler 19 is located on the upstream side of the filling machine 12. The transmission belt 17 is used to carry the iron can 20. An inner liner bag 21 is provided inside the iron can 20. The bottom shape of the leveler 19 is adapted to the opening of the iron can 20.

[0036] As a preferred embodiment, please refer to Figure 1 and Figure 4 A rotating block 4 is also fixedly connected to the drive shaft 3.

[0037] As a preferred embodiment, please refer to Figure 1 The device also includes a limiting block 7, which is fixedly connected to the frame 1 and positioned near the rotation path of the abutment block 6.

[0038] As a preferred embodiment, please refer to Figure 1 The device also includes a support plate 22, which is fixedly connected to the frame 1, and one end of the driven shaft 16 is rotatably connected to the support plate 22.

[0039] As a preferred embodiment, please refer to Figure 1To clarify the supply path of the sealant, the inlet of the filler 12 is connected to the outlet of the hose 11, and the inlet of the hose 11 is connected to the delivery pipe 14.

[0040] In a preferred embodiment, to achieve precise motion synchronization, the active circular pin component 5 and the abutment block 6 have a preset circumferential relative installation position on the drive shaft 3.

[0041] Working principle: Before the filling operation, the iron can 20 placed on the conveyor belt 17 has an inner liner bag 21 inside. The iron can 20 first moves to the bottom of the leveler 19. The electric push rod 18 is started, driving the leveler 19 to move downward to flatten the inner liner bag 21 inside the iron can 20 and prevent the inner liner bag 21 from wrinkling.

[0042] During filling, motor 2 starts, and the output end of motor 2 drives drive shaft 3 to rotate. Rotating block 4, active round pin component 5 and abutment block 6, which are fixedly connected to drive shaft 3, rotate synchronously with drive shaft 3.

[0043] In the first transmission branch, during the rotation of the active round pin component 5, its pin will periodically insert into the groove of the driven groove wheel 8 fixedly connected to the active shaft 15, pushing the driven groove wheel 8 to rotate by a preset angle. The driven groove wheel 8 drives the active shaft 15 to rotate, and the active shaft 15 drives the driven shaft 16 to rotate synchronously through the transmission belt 17. The driven shaft 16 supported by the support plate 22 follows, and the transmission belt 17 thus achieves intermittent forward movement, driving the iron can 20 to move intermittently below the filling device 12.

[0044] In the second transmission branch, the abutment block 6, which rotates synchronously with the active round pin component 5, periodically abuts and pushes the bottom end of the round rod 9 with its outer circumference. The round rod 9 slides up and down in the frame 1 and drives the filling device 12 to perform intermittent up and down reciprocating motion synchronously through the connector 10 at the upper end. The limiting block 7 is set near the rotation path of the abutment block 6 to ensure its stable operation.

[0045] The key to the synchronous coordination lies in the fact that the active round pin component 5 and the abutment block 6 have a preset circumferential relative installation position on the drive shaft 3. This positional relationship ensures that when the active round pin component 5 is inserted into the driven groove wheel 8 to drive the transmission belt 17 to move, the convex surface of the abutment block 6 pushes up the round rod 9, so that the filling device 12 is in the raised position. When the active round pin component 5 disengages from the driven groove wheel 8 and the transmission belt 17 stops moving, the non-convex surface of the abutment block 6 rotates away from the round rod 9, and the filling device 12 descends under its own weight or the action of the return spring, aligning with the stationary iron can 20.

[0046] At this time, the polysulfide sealant stored in the storage tank 13 enters the filling machine 12 through the delivery pipe 14 and the hose 11 that can adapt to the up and down movement of the filling machine 12, and fills the inner liner bag 21 in the iron can 20. After the filling is completed, the drive shaft 3 continues to rotate and repeats the above cycle, realizing the automatic and precise synchronization of the can conveying and filling actions.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
