Description

Technical Field

[0001] This utility model relates to the technical field of adhesive production equipment, and in particular to an adhesive raw material feeding device. Background Technology

[0002] Adhesive production lines are developing towards higher speeds and continuous operation, and precise and clean material feeding has become a key factor determining finished product quality and capacity utilization. In recent years, with the widespread use of high-viscosity, multi-component adhesive formulations, the requirements for equipment sealing, residue control, and automation in the feeding process have been further amplified.

[0003] In current industrial production scenarios, a common practice is to place a high-level silo above the mixing tank, and feed solid powder or granules into the tank via gravity feeding or variable frequency screw feeding. Some solutions use a combination of vacuum suction and manual valve opening for intermittent feeding. While these arrangements can meet basic feeding needs to a certain extent, they reveal significant problems when facing frequent formula changes and manual monitoring of material levels, such as the difficulty in completely emptying the material discharge channel and the inability to weigh materials in real time. The core flaw of existing technologies lies in their inability to effectively prevent material stagnation in the conveying channel while ensuring feeding accuracy, leading to decreased production efficiency and increased raw material waste. Utility Model Content

[0004] The purpose of this invention is to propose an adhesive raw material feeding device to solve the technical problem that existing technologies cannot avoid material stagnation in the conveying channel and waste of raw materials while ensuring feeding accuracy.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: An adhesive raw material feeding device includes a mixing tank with an opening for feeding raw materials on one side of its top; a support frame installed on one side of the mixing tank; a hopper installed on the support frame and located above the opening; a lifting mechanism installed on the support frame and located below the hopper, the lifting mechanism being connected to the hopper and capable of descending to connect with the opening; and a fan installed on the support frame and connected to the lifting mechanism, for blowing residual raw materials in the lifting mechanism into the mixing tank.

[0006] By adopting the above technical solution, the lifting mechanism can flexibly connect to the opening of the mixing tank, realizing a quick switch between feeding and closing; after feeding, the blower blows away the residual raw materials inside the lifting mechanism to avoid retention and improve batch purity.

[0007] Furthermore, a weighing sensor is provided between the hopper and the support, and a through groove is provided on the support for the hopper to pass through. A frame is fixedly provided around the through groove, and the weighing sensor is installed on the frame and supports the hopper.

[0008] By adopting the above technical solution, the weighing sensor can detect changes in the weight of the silo in real time, providing data support for accurate feeding and reducing human error.

[0009] Furthermore, the lifting mechanism includes a first hydraulic cylinder fixedly mounted on the bracket, a horizontal plate mounted on the piston rod of the first hydraulic cylinder, and a connecting cylinder fixedly mounted on the horizontal plate. The opening of the mixing tank is surrounded by a receiving cylinder that docks with the connecting cylinder.

[0010] By adopting the above technical solution, the first hydraulic cylinder drives the horizontal plate and the connecting cylinder to rise and fall, so as to achieve reliable docking between the connecting cylinder and the receiving cylinder and ensure the sealing of the feeding port.

[0011] Furthermore, a telescopic hose is provided between the hopper and the connecting cylinder, with the top end of the telescopic hose communicating with the hopper and the bottom end communicating with the connecting cylinder.

[0012] By adopting the above technical solution, the telescopic hose maintains flexible connection between the hopper and the connecting cylinder during the lifting process, preventing material leakage or blockage.

[0013] Furthermore, a buffer tube is slidably sleeved on the outside of the connecting cylinder, and a spring is provided between the buffer tube and the connecting cylinder. The buffer tube abuts against the receiving cylinder when the connecting cylinder descends.

[0014] By adopting the above technical solution, the buffer tube and spring form a buffer structure, which reduces the impact when the connecting cylinder and the receiving cylinder are connected, and improves the service life of the equipment.

[0015] Furthermore, the hopper includes a hopper body fixedly mounted on the weighing sensor, a hopper cover rotatably mounted at the bottom of the hopper body, a second hydraulic cylinder that drives the hopper cover to rotate, and an end cover that is pulled out from the top of the hopper body. The top and bottom of the hopper body are respectively provided with a feed inlet and a discharge outlet.

[0016] By adopting the above technical solution, the second hydraulic cylinder controls the opening and closing of the hopper cover to achieve quantitative material feeding; the pull-out structure of the end cover facilitates quick closure of the feed inlet and prevents foreign objects from entering.

[0017] Furthermore, a bottom compartment is fixedly installed at the bottom of the silo body, and the fan is connected to the bottom compartment through a pipeline. A ventilation pipe is bent inside the bottom compartment and extends to the lifting mechanism.

[0018] By adopting the above technical solution, the bottom compartment and the ventilation pipe form a directional airflow channel, so that the blower sweeps the inside of the lifting mechanism, further reducing residue.

[0019] Furthermore, a pull-out groove is horizontally provided on the top of the bin, and the end cap is inserted into the pull-out groove to cover the feed inlet. The bin cover is arc-shaped and matches the shape of the discharge outlet.

[0020] By adopting the above technical solution, the arc-shaped hopper cover fits tightly with the discharge port, and the pull-out groove cooperates with the end cover to achieve rapid opening and closing, improving the convenience of operation and sealing performance.

[0021] Compared with the prior art, the present invention has the following beneficial effects: The adhesive raw material feeding device of this utility model, through the linkage of the lifting mechanism and the fan, can completely remove residual materials in the lifting channel and avoid cross-contamination; the weighing sensor monitors the weight of the hopper in real time to achieve accurate quantitative feeding and reduce raw material waste; the telescopic hose and buffer tube structure ensures flexible connection and buffering shock absorption during the lifting process, improving operational stability; the arc-shaped hopper cover and pull-out end cover design achieve quick opening and closing and good sealing, reducing the intensity of manual intervention.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] This embodiment relates to an adhesive raw material feeding device, the overall structure of which is as follows: Figure 1 and Figure 4 As shown, it includes a mixing tank 1, a support 3, a hopper 6, a lifting mechanism 7, and a blower 8.

[0030] The mixing tank 1 has an opening 2 for feeding raw materials on one side of the top. A support 3 is installed on one side of the mixing tank 1. A hopper 6 is installed on the support 3 and located at the top of the opening 2. A lifting mechanism 7 is installed on the support 3 and located at the bottom of the hopper 6. The lifting mechanism 7 connects the hopper 6 to the opening 2. A blower 8 is installed on the support 3 and connected to the lifting mechanism 7. The blower 8 blows the raw materials remaining in the lifting mechanism 7 into the mixing tank 1.

[0031] It is worth mentioning that the height of the support 3 is higher than that of the mixing tank 1. The support 3 consists of a platform and four legs. The platform is installed on top of the four legs, with two legs flush with the bottom of the mixing tank 1 and the other two legs installed on top of the mixing tank 1. The hopper 6 is installed on the platform, and the lifting mechanism 7 is located at the bottom of the hopper 6. The lifting mechanism 7 is connected to the hopper 6. After the lifting mechanism 7 is lowered, it can connect with the opening 2. This setting ensures that the raw materials in the hopper 6 can be transported into the mixing tank 1. The purpose of setting the lifting mechanism 7 is to add materials at any time or close the opening 2 at any time to facilitate the mixing of the mixing tank 1. The setting of the blower 8 can ensure that the raw materials remaining in the lifting mechanism 7 can be completely transported into the mixing tank 1, avoiding the residue in the lifting mechanism 7.

[0032] Based on the above overall introduction, this embodiment presents an exemplary structure of the adhesive raw material feeding device, such as... Figure 2 As shown, a weighing sensor 11 is installed between the hopper 6 and the support 3. A through-slot 4 is provided on the support 3 for the hopper 6 to pass through. A frame 5 surrounds the through-slot 4 of the support 3, and the weighing sensor 11 is mounted on the frame 5. It should be noted that the weighing sensor 11 is connected to an external controller, which can weigh the raw materials in the hopper 6. The controller is a common control device in the prior art and will not be described in detail here. The through-slot 4 is located on the platform, and the bottom of the hopper 6 passes through the through-slot 4 and connects to the top of the lifting mechanism 7. The frame 5 serves to house the weighing sensor 11 and the hopper 6. When raw materials are conveyed into the hopper 6, the weighing sensor 11 can transmit an electrical signal to the controller, allowing personnel to observe the amount of raw materials conveyed, thereby improving the production quality of the adhesive.

[0033] As a preferred implementation method, such as Figure 3As shown, the lifting mechanism 7 in this embodiment includes a first hydraulic cylinder 701 fixedly mounted on the bracket 3, a horizontal plate 702 mounted on the piston rod of the first hydraulic cylinder 701, a connecting cylinder 703 mounted on the horizontal plate 702, a receiving cylinder 707 surrounding the opening 2 of the mixing tank 1, and a telescopic hose 704 between the hopper 6 and the connecting cylinder 703. It should be noted that the cylinder body of the first hydraulic cylinder 701 is installed on the platform, and in this embodiment, four cylinders are used, arranged around the edge of the hopper 6. The piston rod of the first hydraulic cylinder 701 passes through the platform and is fixedly connected to the horizontal plate 702. This arrangement ensures that the first hydraulic cylinder 701 can drive the horizontal plate 702 to rise and fall. The connecting cylinder 703 follows the horizontal plate 702 to rise and fall, ensuring that the connecting cylinder 703 can communicate with the receiving cylinder 707. When feeding is required, the connecting cylinder descends to communicate with the receiving cylinder 707. After feeding is completed, when the mixing tank 1 needs to be stirred, the connecting cylinder 703 rises, and the receiving cylinder 707 can be covered with a cover plate. The bottom end of the telescopic hose 704 is connected to the connecting cylinder 703, and the top end is connected to the hopper 6. The raw materials in the hopper 6 are sequentially transported to the mixing tank 1 through the telescopic hose 704, the connecting cylinder 703, and the receiving cylinder 707. The telescopic hose 704 can ensure that the connecting pipe is always connected to the hopper 6 when it rises and falls.

[0034] As a preferred option, such as Figure 4 As shown, in this embodiment, a buffer tube 705 is sleeved on the connecting tube, and a spring 706 is provided between the buffer tube 705 and the connecting tube. Specifically, the buffer tube 705 can move up and down on the connecting tube. A retaining ring connecting the spring 706 is fixedly provided on the outer wall of the connecting tube. The top end of the spring 706 is fixedly connected to the retaining ring, and the bottom end is connected to the buffer tube 705. When the connecting tube descends, the buffer tube 705 abuts against the receiving tube, and the spring 706 is subjected to force, thereby achieving a buffering effect.

[0035] As a preferred implementation method, such as Figure 5 and Figure 6As shown, the hopper 6 in this embodiment includes a hopper body 601 fixedly mounted on the weighing sensor 11, a hopper cover 602 rotatably mounted at the bottom of the hopper body 601, a second hydraulic cylinder 603 that drives the hopper cover 602 to rotate, and an end cover 604 that is pulled out and mounted on the top of the hopper body 601. The top and bottom of the hopper body 601 are respectively provided with a feed inlet 605 and a discharge outlet 606. It should be noted that a pull-out groove 608 is horizontally opened on the top of the silo body 601, and the end cover 604 is inserted into the pull-out groove 608. This setting ensures that the feed inlet 605 is covered to prevent dust or other things from entering the silo body 601. The discharge port 606 and the silo cover 602 are set in an arc shape. The second hydraulic cylinder 603 drives the silo cover 602 to rotate, which can control the opening or closing of the discharge port 606. When the weighing sensor 11 is weighing, the silo cover 602 can be controlled to close the discharge port 606 to ensure that the weight of the raw material can be accurately weighed. After the weighing is completed, the silo cover 602 is controlled to open the discharge port 606, and the weighed raw material is discharged into the lifting mechanism 7. This setting completes the precise feeding.

[0036] As a preferred option, such as Figure 7 As shown, in this embodiment, a bottom chamber 607 is fixedly installed at the bottom of the silo body 601. The blower 8 is connected to the bottom chamber 607 through a pipe 9. A ventilation pipe 10 is bent inside the bottom chamber 607 and extends to the lifting mechanism 7. Specifically, the bottom chamber 607 is located at the discharge port 606. One end of the pipe 9 is connected to the air outlet of the blower 8, and the other end is connected to the side wall of the bottom chamber 607. One end of the ventilation pipe is connected to the pipe 9, and the other end is bent and extended to the top of the telescopic hose 704. This arrangement ensures that the raw materials remaining in the lifting mechanism 7 can be blown into the mixing tank 1. A filter is connected to the mixing tank 1, and a solenoid valve is installed between the filter and the mixing tank 1. The purpose of installing the filter and the solenoid valve is that when the blower 8 blows, airflow will be generated. The airflow can be discharged through the solenoid valve and the filter. The filter can prevent the raw materials from being discharged. The solenoid valve can be closed when the blower 8 is not working or when the material is being stirred. This arrangement ensures that the material will not enter the filter when the mixing tank 1 is being stirred. The filter is a common dust filter in the prior art, which will not be described in detail here.

[0037] In this embodiment, the adhesive raw material feeding device, through the linkage of the lifting mechanism 7 and the fan 8, can completely remove residual materials in the lifting channel and avoid cross-contamination; the weighing sensor 11 monitors the weight of the hopper 6 in real time to achieve accurate quantitative feeding and reduce raw material waste; the structure of the telescopic hose 704 and the buffer tube 705 ensures flexible connection and buffering shock absorption during the lifting process, improving operational stability; the arc-shaped hopper cover 602 and the pull-out end cover 604 design achieve quick opening and closing and good sealing, reducing the intensity of manual intervention.

[0038] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
