Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, specifically to a quantitative feeding device for powder coating. Background Technology

[0002] Powder coatings are solvent-free coatings in powder form, developed from powdered plastics. During the coating process, the coating is applied in powder form to form a protective film on the workpiece. They are generally composed of resin, curing agent, filler, and additives. The resin is the film-forming substance, determining the basic properties of the coating; the curing agent undergoes a cross-linking reaction with the resin, causing the coating to solidify; fillers can improve the physical properties of the coating and reduce costs; and additives improve the processing performance and enhance the coating's overall performance.

[0003] A quantitative feeding device is required in the powder coating production process. Chinese utility model patent CN222630540U discloses a quantitative feeding device for powder coatings, including a feeding hopper, a quantitative mechanism for quickly adjusting the amount of powder coating fed from the hopper, and a discharge mechanism. This utility model changes the amount of powder coating fed by controlling the opening time of the gap between the conical structure of the quantitative tube and the discharge hood. Simultaneously, the rotation of the rotating shaft drives the screw rod and sliding sleeve to rotate synchronously. The rotation of the screw rod reduces the amount of powder coating accumulating in the middle of the quantitative tube, preventing compression of the powder coating on the inner wall of the tube. At the same time, the sliding sleeve drives the actuating frame to rotate past the teeth at the lower end of the quantitative tube, generating vibration to prevent the powder coating inside the tube from clogging.

[0004] However, this utility model does not have a structure for weighing the amount of material being fed, so the workers cannot determine how to achieve a quantitative effect based on the actual feeding situation. This may lead to deviations in the feeding amount, affecting the actual feeding effect and failing to meet production needs. Therefore, a quantitative feeding device for powder coatings is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quantitative feeding device for powder coatings, which has the advantage of convenient weighing. It solves the problem that existing feeding devices do not have a structure for weighing the feeding amount, making it impossible for operators to determine how to achieve quantitative results based on the actual feeding situation, which may lead to deviations in the feeding amount and affect the actual feeding effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quantitative feeding device for powder coating, comprising a workbench and a storage tank fixedly connected to the top of the workbench, wherein a quantitative tank is provided on one side of the workbench, and a weighing mechanism capable of weighing is provided on the outside of the quantitative tank;

[0007] The weighing mechanism includes a support platform fixedly connected to one side of the workbench, a metering tank passing through the support platform, a fixing plate fixedly connected to the front of the metering tank, a support spring fixedly connected between the fixing plate and the support platform, an mounting plate fixedly connected to the front of the metering tank, a weighing sensor fixedly connected to the side of the support platform near the mounting plate, and the bottom of the mounting plate in contact with the weighing sensor.

[0008] Furthermore, there are two fixing plates and two supporting springs, with the two supporting springs symmetrically distributed on the left and right sides of the metering tank.

[0009] Furthermore, a feeding pipe is fixedly connected to the bottom of the metering tank. A drive gear and a driven gear are rotatably connected to both the front and back of the feeding pipe. The drive gear and the driven gear mesh with each other. A baffle is fixedly connected to the side of the drive gear and the driven gear near the feeding pipe.

[0010] Furthermore, a support frame is fixedly connected to the side of the metering tank away from the workbench, and an electric push rod extending to the outside of the support frame is rotatably connected inside the support frame. The output end of the electric push rod is fixedly connected to the right-side baffle.

[0011] Furthermore, sealing strips are fixedly connected to opposite sides of the baffles, and the discharge pipe is located inside both baffles simultaneously.

[0012] Furthermore, a support column is fixedly connected between the workbench and the storage tank, and a connecting pipe extending into the workbench is fixedly connected to the bottom of the storage tank.

[0013] Furthermore, a feeding cylinder extending to the top of the metering tank is fixedly connected inside the workbench. A drive motor is fixedly connected to the end of the feeding cylinder away from the metering tank, and a spiral conveyor frame extending into the feeding cylinder is fixedly connected to the output shaft of the drive motor.

[0014] Furthermore, the feeding cylinder and the storage tank are connected by a connecting pipe, and a discharge pipe is fixedly connected to the bottom of the feeding cylinder near the metering tank.

[0015] Compared with the prior art, the present invention provides a quantitative feeding device for powder coatings, which has the following beneficial effects:

[0016] 1. This powder coating quantitative feeding device supports the quantitative container by setting a fixed plate and a support spring. By setting an mounting plate and a weighing sensor, pressure is generated on the weighing sensor when there is powder coating inside the quantitative container, which facilitates the weighing of the powder coating inside the quantitative container. This makes it easier for the staff to feed the powder in a quantitative manner and allows the staff to better control the accuracy of the feeding amount.

[0017] 2. This powder coating quantitative feeding device uses an electric push rod to drive the right-side baffle to rotate. Through the installation of transmission and driven gears, both baffles can rotate simultaneously, facilitating feeding control and achieving the desired feeding effect. This solves the problem of existing feeding devices lacking a weighing structure for the feeding quantity, which prevents operators from determining the optimal quantitative feeding method based on actual feeding conditions, potentially leading to deviations in the feeding quantity and affecting the actual feeding effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 2This embodiment of a powder coating metering device includes a workbench 1 and a storage tank 2 fixedly connected to the top of the workbench 1. A metering tank 3 is provided on one side of the workbench 1. A weighing mechanism capable of weighing is provided on the outside of the metering tank 3. The weighing mechanism includes a support platform 4 fixedly connected to one side of the workbench 1. The metering tank 3 passes through the support platform 4. A fixing plate 5 is fixedly connected to the front of the metering tank 3. A support spring 6 is fixedly connected between the fixing plate 5 and the support platform 4. An mounting plate 7 is fixedly connected to the front of the metering tank 3. A weighing sensor 8 is fixedly connected to the side of the support platform 4 near the mounting plate 7. The bottom of the mounting plate 7 is in contact with the weighing sensor 8.

[0024] Specifically, there are two fixed plates 5 and two support springs 6, with the two support springs 6 symmetrically distributed on the left and right sides of the metering tank 3.

[0025] It should be noted that a controller is fixedly connected to the front of the workbench 1. The controller is connected to the load cell 8 via a signal connection. The load cell 8 is a resistance strain gauge load cell, which is based on the strain effect of metal or semiconductor materials, that is, the resistance value of a conductor changes when it is deformed under force. The elastic body of the sensor (such as alloy steel, aluminum alloy, etc.) deforms under force, and the strain gauge attached to the elastic body deforms accordingly, changing the resistance value. The change in resistance is converted into a voltage signal output through a bridge circuit.

[0026] Please see Figure 1 and Figure 3 In this embodiment, a feeding pipe 9 is fixedly connected to the bottom of the metering tank 3. A transmission gear 10 and a driven gear 11 are rotatably connected to the front and back of the feeding pipe 9. The transmission gear 10 and the driven gear 11 mesh with each other. A baffle 12 is fixedly connected to the side of the transmission gear 10 and the driven gear 11 near the feeding pipe 9. A support frame 13 is fixedly connected to the side of the metering tank 3 away from the workbench 1. An electric push rod 14 extending to the outside of the support frame 13 is rotatably connected inside the support frame 13. The output end of the electric push rod 14 is fixedly connected to the right baffle 12.

[0027] Specifically, sealing strips are fixedly connected to opposite sides of the baffle 12, and the discharge pipe 9 is located inside both baffles 12.

[0028] It should be noted that by setting the electric push rod 14 to drive the right side baffle 12 to rotate, and by setting the transmission gear 10 and the driven gear 11, the two baffles 12 can rotate at the same time, thereby facilitating the control of material feeding and achieving the effect of material feeding at the same time.

[0029] Please see Figure 1In this embodiment, a support column 15 is fixedly connected between the workbench 1 and the storage tank 2. A connecting pipe 16 extending into the workbench 1 is fixedly connected to the bottom of the storage tank 2. A feeding cylinder 17 extending into the top of the metering tank 3 is fixedly connected inside the workbench 1. A drive motor 18 is fixedly connected to the end of the feeding cylinder 17 away from the metering tank 3. A spiral conveyor frame 19 extending into the feeding cylinder 17 is fixedly connected to the output shaft of the drive motor 18.

[0030] Specifically, the feeding cylinder 17 is connected to the storage tank 2 through a connecting pipe 16, and a discharge pipe is fixedly connected to the bottom of the feeding cylinder 17 near the metering tank 3.

[0031] It should be noted that by controlling the drive motor 18, the feeding effect inside the metering tank 3 can be controlled.

[0032] The working principle of the above embodiments is as follows:

[0033] First, the operator starts the drive motor 18 to rotate the screw conveyor 19. Then, the powder coating inside the storage tank 2 is conveyed to the metering tank 3 through the feeding cylinder 17. At this time, the weight of the metering tank 3 increases, which will put pressure on the weighing sensor 8, thereby weighing the powder coating inside the metering tank 3. When the weight reaches the preset value, the feeding into the metering tank 3 will stop. At the same time, the electric push rod 14 will be started to rotate the baffle 12, thereby realizing the unloading process.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
