Description

Technical Field

[0001] This application belongs to the technical field of sealant production equipment, and more specifically, relates to an automated two-component sealant dispensing equipment. Background Technology

[0002] The production of two-component sealants (two-component polyurethane sealants, two-component polysulfide sealants) typically includes processes such as feeding, dispersion and mixing, barrel filling, and capping. In the production of each component, the mixing tank delivers the mixed sealant to a temporary storage tank above the filling and metering unit. Workers place the packaging barrels at the filling and metering unit position, then manually open the filling valve below the temporary storage tank. Simultaneously, they observe the sealant level in the packaging barrel to determine the filling volume. After filling, the sealant is sent to the sealing machine for capping, completing the entire packaging process.

[0003] The current production method relies entirely on manual operation for filling volume, which is labor-intensive and results in low filling accuracy as workers visually determine the volume. Furthermore, since two-component sealants consist of two components, each requiring a separate production line, the number of production lines needs to be doubled. This is especially true as the variety of sealants increases, necessitating a balance between equipment investment, production line layout, production efficiency, and production flexibility.

The weighing and metering component is adapted to control the electric discharge unit to stop when the load of the filling roller reaches a predetermined value.

[0006] In some embodiments, there are multiple sealant dispersion mixing tanks and multiple filling metering units, and they are arranged in a one-to-one correspondence.

The discharge pipe of the electric discharge unit forms two branches, each branch is equipped with a control valve, and the two branches extend above the filling positions corresponding to the two feed ports.

[0010] In some embodiments, the end of the discharge pipe extends directly above the filling roller conveyor and has a downward bend.

[0011] In some embodiments, the filling metering unit further includes a pusher mechanism located above the filling roller conveyor and adapted to push the sealing glue bucket along the filling roller conveyor.

[0012] In some embodiments, the pushing mechanism includes: The telescopic unit is located at the end of the filling roller conveyor, with the telescopic end facing the outlet end of the filling roller conveyor.

[0014] In some embodiments, the weighing and metering component further includes a foot switch connected to the input terminal of the controller, the foot switch controlling the opening of the electric discharge unit via the controller.

[0015] The advantages of the automated two-component sealant dispensing equipment provided in this application embodiment are as follows: Compared with the prior art, in the automated two-component sealant dispensing equipment of this application embodiment, the weighing and metering components of each filling metering unit are connected to the electric discharge unit of the corresponding sealant dispersion mixing tank. When the sealant barrel on the filling roller conveyor is full, the load capacity of the filling roller conveyor reaches a predetermined value, and the weighing and metering components control the electric discharge unit to stop, thereby accurately controlling the filling amount of the sealant barrel.

In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0024] Please refer to the following: Figures 1 to 3 The automated two-component sealant dispensing equipment provided in the embodiments of this application will now be described. An automated two-component sealant dispensing equipment, suitable for dispensing two-component sealants, includes: A sealant dispersion mixing tank with an electric discharge unit; and The filling and metering unit includes a filling roller conveyor and a weighing and metering component for measuring the load capacity of the filling roller conveyor; The discharge pipe of the electric discharge unit extends to be opposite the filling roller conveyor of the filling metering unit; The weighing and metering component of the filling metering unit controls the electric discharge unit of the sealant dispersion mixing tank. The weighing and metering component is adapted to control the electric discharge unit to stop when the load of the filling roller reaches a predetermined value.

[0025] Compared with the prior art, the automated two-component sealant dispensing equipment of this application embodiment controls the electric discharge unit of the corresponding sealant dispersion mixing tank through the weighing and metering components of each filling metering unit. When the sealant barrel on the filling roller conveyor is full, the load capacity of the filling roller conveyor reaches the predetermined value, and the weighing and metering components control the electric discharge unit to stop. This allows for accurate control of the filling amount of the sealant barrel. Moreover, the entire filling process can rely on the filling roller conveyor for transportation, eliminating the need for manual handling and greatly reducing the workload of workers.

[0026] In this embodiment, the filling roller conveyor can adopt a common roller conveyor structure. The weighing and metering component detects the total weight of the filling roller conveyor and the load above it (the sealant barrel and the sealant inside). During filling, the weighing and metering component monitors the change in the total weight of the filling roller conveyor and the load above it (the sealant barrel and the sealant inside) to determine the weight of the sealant poured into the barrel.

[0027] The sealant dispersion mixing tank produces a sealant component and is equipped with a corresponding filling and metering unit. It can package the sealant according to the requirements of that component using appropriate packaging containers and filling volumes. The sealant dispersion mixing tank is equipped with an electric discharge unit, which directly delivers the mixed and dispersed sealant to the filling and metering unit through a discharge pipe. Simultaneously, the weighing and metering components of the filling and metering unit are connected to the electric discharge unit, controlling its start and stop, directly determining the start and stop of filling.

[0028] Please see Figure 1 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, the sealant dispersion mixing tank and the filling metering unit are each provided in multiple quantities and are set up one by one. The automated two-component sealant dispensing equipment also includes: The main conveyor roller conveyor has multiple feed inlets and at least one discharge inlet; the outlet ends of the multiple filling roller conveyors are respectively connected to each feed inlet of the main conveyor roller conveyor. The sealing unit has a feed inlet; the feed inlet of the sealing unit is connected to the discharge inlet of the main conveyor roller.

[0029] In this embodiment, the sealant dispersion mixing tank and the filling metering unit are set up one-to-one. Each sealant dispersion mixing tank is equipped with an electric discharge unit, which directly sends the mixed and dispersed sealant to the corresponding filling metering unit through the discharge pipe for filling. At the same time, the weighing and metering component of the filling metering unit is connected to the electric discharge unit, controlling the start and stop of the electric discharge unit, which directly determines the start and stop of filling.

[0030] Multiple sealant dispersion and mixing tanks can produce the same sealant component or different sealant components according to actual needs. Each sealant dispersion and mixing tank is equipped with a corresponding filling and metering unit, facilitating the filling of different sealant components. Appropriate packaging containers and filling volumes can be used according to the requirements of each component without switching, ensuring production efficiency. The main conveyor roller conveyor has multiple feeding ports. Sealant containers filled by each filling and metering unit can be directly collected from their respective filling roller conveyors to the main conveyor roller conveyor, and then transported by the main conveyor roller conveyor to the capping unit for unified capping. This optimizes the packaging process of two-component sealant, flexibly adapting to various production situations and reducing equipment investment to a certain extent.

[0031] In practice, the structure of the capping unit can refer to the capping equipment used for sealing glue barrels on the market. The structure of the main conveyor roller can also refer to the conveyor roller on the market, which is used to automatically send the sealing glue barrels on it to the capping unit at the feed port.

[0032] Please see Figure 1 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, the sealant dispersion mixing tank and the filling metering unit are located on both sides of the main conveyor roller conveyor, and the discharge pipe of the electric discharge unit passes over the main conveyor roller conveyor and extends to the top of the corresponding filling roller conveyor.

[0033] In this embodiment, the sealant dispersion and mixing tank and the filling and metering unit are located on opposite sides of the main conveyor roller conveyor, making more rational use of the space on both sides of the main conveyor roller conveyor. The sealant dispersion and mixing tank is set on one side of the main conveyor roller conveyor, and the filling and metering unit and the corresponding packaging barrel storage area are set on the other side, avoiding the sealant dispersion and mixing tank and the filling and metering unit and the corresponding packaging barrel storage area from crowding on the same side of the main conveyor roller conveyor.

[0034] Please see Figure 1 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, the feeding port is located on the side of the main conveyor roller away from the sealant dispersion mixing tank, the filling metering unit is located on the side of the main conveyor roller away from the sealant dispersion mixing tank, and the filling roller is connected to the feeding port.

[0035] In practice, to prevent the sealant buckets from falling off the sides, the main conveyor rollers are typically equipped with baffles or similar structures. A notch in these baffles or similar structures forms the feeding port. The size of the feeding port is designed to allow the sealant buckets to pass through, enabling them to be pushed onto the main conveyor rollers. The filling rollers of the filling and metering unit are aligned with the feeding port and at the same height, allowing the operator or a pushing mechanism to push the sealant buckets onto the main conveyor rollers.

[0036] Please see Figure 1 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, a feeding port is formed on one side and at the end of the main conveyor roller, and a filling metering unit can be connected to either of the two feeding ports. The discharge pipe of the electric discharge unit forms two branches, each branch is equipped with a control valve, and the two branches extend to the filling positions corresponding to the two feed ports.

[0037] The filling position corresponding to the feed port is the position that can be used to install the filling metering unit. In actual production, the filling position corresponding to the feed port may be occupied by other equipment.

[0038] In this embodiment, two feeding ports are formed at the end of the main conveyor roller. A filling metering unit can be connected to either feeding port according to actual needs (e.g., the filling position corresponding to one feeding port is occupied by other equipment).

[0039] The electric discharge unit has control valves installed on both branches of the discharge pipe. By closing one control valve and opening the other, the sealant in the discharge pipe can flow only to the filling position where the filling metering unit is located.

[0040] Please see Figure 2 and 3 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, the end of the discharge pipe extends directly above the filling roller conveyor and is provided with a downward bend.

[0041] In this embodiment, the sealant discharged from the discharge pipe flows downwards into the sealant bucket on the filling roller conveyor to avoid splashing. When the discharge pipe has branches, the end of the discharge pipe is also the end of the branch.

[0042] Please see Figures 1 to 3 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, the filling metering unit further includes a pushing mechanism located above the filling roller conveyor and adapted to push the sealant barrel out along the filling roller conveyor.

[0043] In this embodiment, the filled sealing glue bucket can be pushed from the filling roller conveyor onto the main conveyor roller conveyor by the pushing mechanism, further reducing the workload of workers.

[0044] Please see Figures 1 to 3 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, the pushing mechanism includes: The telescopic unit is located at the end of the filling roller conveyor, with the telescopic end facing the outlet end of the filling roller conveyor. The pusher, which is arc-shaped and matches the outer surface of the sealing glue barrel, is located at the telescopic end of the telescopic unit.

[0045] In this embodiment, the end of the filling roller conveyor that connects with the feed inlet of the main conveyor roller conveyor is the outlet end, and the end away from the feed inlet of the main conveyor roller conveyor is the end end. The telescopic unit is used to push the sealing glue bucket along the filling roller conveyor toward the main conveyor roller conveyor; it can be a horizontal pneumatic cylinder or hydraulic cylinder. The pushing member can be an arc-shaped strip; during the pushing process, the sealing glue bucket is confined within the recessed portion of the pushing member to prevent it from shifting to either side.

[0046] Please see Figure 2 and 3 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, the weighing and metering component includes: High-altitude support; The sensing components are located at the top of the height support; and The controller has its input end connected to the sensing component and its output end connected to the electric feeding unit. The filling roller conveyor is supported on the sensing components, and the pushing mechanism is fixed to the height bracket.

[0047] In this embodiment, a height bracket is used for support to ensure that the filling roller conveyor is at the same height as the main conveyor roller conveyor. The filling roller conveyor is installed on top of the sensing component, which can monitor the total weight of the filling roller conveyor, the sealant on it, and the barrel. The pushing mechanism is fixed to the height bracket to reduce the total weight on the sensing component and prevent the movement of the pushing mechanism from affecting the detection of the weighing and metering component.

[0048] In practice, a height support can be a support consisting of multiple legs.

[0049] The sensing assembly may include one or more sensors, which are supported below the filling roller conveyor to detect the total weight of the filling roller conveyor, the sealing barrel on it, and the internal sealant.

[0050] The controller can filter, amplify, and process the weight signal input from the sensing components through hardware or software, and control the start and stop of the electric feeding unit accordingly.

[0051] The telescopic unit of the pushing mechanism is fixed to the end of the height support away from the feeding port by a fixing plate.

[0052] Please see Figure 3 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, the weighing and metering component also includes a foot switch, which is connected to the input terminal of the controller. The foot switch controls the opening of the electric discharge unit through the controller.

[0053] In this embodiment, the operator can control the opening of the electric feeding unit by stepping on the foot switch, which is convenient for operation.

[0054] Please see Figure 2 and 3 As a specific embodiment of the automated two-component sealant dispensing equipment provided in this application, the electric discharge unit is an electric screw conveyor or an electric pump.

[0055] In this embodiment, the electric screw conveyor ( Figure 2 ) or electric pump ( Figure 3 It can be easily controlled using the electrical signals at the output of the controller.

[0056] In practice, the controller can control the electric screw conveyor or electric pump through built-in or external relays or power switching devices.
