Description

Technical Field

[0001] The utility model relates to the technical field of flour packaging, and specifically, to a flour quantitative weighing device. Background Art

[0002] In the process of flour production and packaging, it is necessary to package flour according to a certain weight or volume. The flour weighing and quantitative taking device can weigh the required amount of flour to ensure that the weight or volume of each bag of flour meets the specified standards.

[0003] Regarding the lifting device, there are many existing technologies, such as:

[0004] Chinese Patent Application No. CN218432037U discloses a metering type flour packaging device, including a bottom plate. Two L-shaped brackets are symmetrically and fixedly installed on the upper surface of the bottom plate. A hopper is fixedly installed between the two L-shaped brackets. The bottom end of the hopper is fixedly installed with a discharge pipe. In the utility model, the motor drives the rotating shaft to rotate, so that the turntable can drive a plurality of packaging bags to rotate below the discharge pipe in turn. When the discharge holes opened on the turntable are aligned with the lower part of the discharge pipe, the flour in the hopper will automatically fall into the flour packaging bag under the action of gravity to realize the filling of flour; after a preset time for filling the flour, the motor controller will start the motor to rotate the turntable by a certain angle until the next discharge hole is aligned with the discharge pipe, and then take down the filled flour bag and replace it with a new flour bag for filling, so as to continuously fill the flour without stopping the machine and improve the packaging efficiency of flour.

[0005] When the existing device is in use, a guide pipe is fixedly installed on the lower surface of the turntable close to the discharge hole, and anti-slip lines are arranged on the outer surface of the guide pipe to prevent the flour packaging bag from falling when the bag mouth of the flour packaging bag is tied to the guide pipe. When a large amount of flour is filled, it is necessary to manually tie and fix the flour bag multiple times and take down the flour bag after filling. The process is relatively cumbersome, which is likely to increase the workload and affect the production efficiency. In view of this, we propose a flour quantitative weighing device. Content of the Utility Model

[0006] The purpose of the utility model is to solve the above-mentioned disadvantages and provide a flour quantitative weighing device;

[0007] To achieve the above purpose, the utility model provides a flour quantitative weighing device, including a base. A pressure plate is slidably connected to the top of the base. Both sides of the top of the pressure plate are fixedly connected with pressure rods, and a pressure block is arranged between the tops of the pressure rods;

[0008] A support port ring is slidably connected to the upper surface of the upper end of the pressure rod, and a support rod is welded on one side between the support port ring and the base;

[0009] A weighing pan is slidably mounted on the surface of the pressure rod, and a lifting assembly is rotatably connected between the bottom of the weighing pan and the top of the pressure plate. When the weighing pan moves downward under pressure, the bottom of the pressure block presses against the top of the support port ring.

[0010] As a further improvement of this technical solution, a rubber pad is provided at the bottom of the pressure block.

[0011] As a further improvement of this technical solution, a groove for the lower end structure of the weighing pan to slide is opened at the top of the base, and a plurality of springs are fixedly connected between the groove opened at the top of the base and the bottom of the weighing pan.

[0012] As a further improvement of this technical solution, the lifting assembly includes a threaded rod fixedly installed at the bottom of the weighing pan, and a sleeve rod is threadedly connected to the lower end surface of the threaded rod.

[0013] As a further improvement of this technical solution, a driven bevel gear is fixedly connected to the lower end surface of the sleeve rod, and a driving bevel gear is engaged with the outer edge of the driven bevel gear. A transmission shaft is fixedly connected to the inner cavity of the driving bevel gear, and one end of the transmission shaft is fixedly connected to one side of the sleeve rod.

[0014] As a further improvement of this technical solution, a handle is fixedly connected to the end of the transmission shaft away from the sleeve rod.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In this flour quantitative weighing device, the bag mouth is supported by the support port ring, and the flour falls into the flour bag on the top of the weighing pan for weighing. When the weighing pan is subjected to the gravity of the flour, it presses against the lifting assembly and slides downward, causing the pressure plate to squeeze the spring and slide downward in the groove on the top of the base. When the pressure plate moves downward, it drives the pressure rod on the top to move downward, so that the bottom of the pressure block presses against the flour bag mouth to fix the bag mouth, facilitating the filling of flour. After the filling and weighing are completed, the lifting assembly drives the height of the weighing pan to decrease, facilitating the workers to pick up the goods. And at the moment when the weighing pan descends, since the top of the flour bag is fixed and will not descend accordingly, the pressure on the top of the weighing pan disappears, and the pressure on the top of the pressure plate also disappears accordingly. The spring rebounds and drives the pressure plate to move upward, driving the pressure rod to move upward, so that the bottom of the pressure block disengages from the bag mouth, and the flour bag loses its fixation and falls on the top of the weighing pan, facilitating the bag picking.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 As shown, this embodiment provides a flour quantitative weighing device, including a pressure plate 11 slidably connected to the top of a base 1. Both sides of the top of the pressure plate 11 are fixedly connected with pressure rods 12, and a pressure block 13 is arranged between the tops of the pressure rods 12;

[0025] A support port ring 14 is slidably connected to the upper surface of the pressure rod 12, and a support rod 15 is welded on one side between the support port ring 14 and the base 1;

[0026] A weighing pan 16 is slidably mounted on the surface of the pressure rod 12, and a lifting assembly 17 is rotatably connected between the bottom of the weighing pan 16 and the top of the pressure plate 11. When the weighing pan 16 moves downward under pressure, the bottom of the pressure block 13 presses against the top of the support port ring 14.

[0027] The improvement of this embodiment lies in that: the bag mouth is supported by the branch mouth ring 14. When filling flour, the flour falls into the flour bag on the top of the weighing pan 16. A weighing sensor is arranged inside the weighing pan 16, which can weigh the flour. When the weighing pan 16 is subjected to the gravity of the flour, it presses against the lifting assembly 17 and slides downward, causing the bottom pressing plate 11 to squeeze the spring 161 and slide downward in the groove on the top of the base 1. When the pressing plate 11 moves downward, it drives the top pressing rod 12 to move downward, so that the bottom of the pressing block 13 presses against the flour bag mouth to fix the bag mouth, facilitating the filling of flour. After the filling and weighing are completed, the distance between the weighing pan 16 and the ground is adjusted through the lifting assembly 17. When the lifting assembly 17 descends, the height of the weighing pan 16 is reduced, facilitating the workers to pick up the goods. Since the flour bag is fixed, it is separated from the top flour bag instantly when the weighing pan 16 descends, the pressure on the top of the weighing pan 16 disappears, the pressure on the top of the pressing plate 11 disappears, the spring 161 rebounds and drives the pressing plate 11 to move upward, the pressing plate 11 jacks up the top pressing rod 12 to move upward, so that the bottom of the pressing block 13 disengages from the bag mouth, and the flour bag loses its fixation and falls on the top of the weighing pan 16, facilitating the bag picking.

[0028] Considering that the quality gradually increases during the flour filling process and the bag mouth is prone to break free due to gravity, therefore, as Figure 4 shown, a rubber pad 131 is provided at the bottom of the pressing block 13. The flour bag mouth is sleeved on the top of the branch mouth ring 14 to open the bag mouth. The bottom of the pressing block 13 presses against the flour bag mouth on the top of the branch mouth ring 14 to fix the bag mouth. At the same time, the rubber pad 131 between the pressing block 13 and the flour bag mouth is squeezed and undergoes compressive deformation, so that the rubber pad 131 can closely fit the surface of the bag mouth, increasing the friction force and further limiting the flour bag mouth to prevent the bag mouth from falling off due to the increase in the flour quality during the filling process, affecting the quantitative filling of flour.

[0029] In order to facilitate the downward sliding of the weighing pan 16 and drive the pressing block 13 to press against the flour bag mouth, therefore, as Figure 3 shown, a groove for the lower end structure of the weighing pan 16 to slide is opened at the top of the base 1. A plurality of springs 161 are fixedly connected between the groove opened at the top of the base 1 and the bottom of the weighing pan 16. During the filling process, the flour falls into the flour bag on the top of the weighing pan 16 for filling and weighing. The weighing pan 16 is subjected to gravity and presses against the lifting assembly 17 to slide downward, causing the pressing plate 11 to squeeze the spring 161 and move downward in the top chute of the base 1, pulling the pressing rod 12 to move downward. The pressing rod 12 drives the pressing block 13 to move downward, and the bottom of the pressing block 13 presses against the flour bag mouth on the top of the branch mouth ring 14 to fix the flour bag mouth, facilitating the flour filling.

[0030] Considering that after the flour filling and weighing are completed, the bag containing flour needs to be taken off from the top of the weighing pan 16, therefore, as Figure 4As shown in the figure, the lifting assembly 17 includes a threaded rod 171 fixedly installed at the bottom of the weighing plate 16, and a sleeve rod 172 is threadedly connected to the lower end surface of the threaded rod 171. By moving the threaded rod 171 up and down inside the sleeve rod 172, the weighing plate 16 is driven to move up and down. When the threaded rod 171 moves upward, the weighing plate 16 is driven to move upward, so that the top of the weighing plate 16 contacts the top of the flour bag, facilitating weighing. When the threaded rod 171 moves downward inside the sleeve rod 172, the weighing plate 16 at the top is driven to move downward, reducing the height between the weighing plate 16 and the ground, facilitating the worker to remove the flour from the top of the weighing plate 16. During the process of the threaded rod 171 driving the weighing plate 16 to descend, since the top of the flour bag opening is fixed and will not move downward accordingly, the pressure on the top of the weighing plate 16 disappears, causing the pressure on the top of the pressing plate 11 to disappear. The spring 161 pushes the pressing plate 11 to rebound upward, and then the pressing plate 11 pushes the lifting rod 12 upward, causing the bottom of the pressing block 13 to disengage from the top of the support port ring 14, and the flour bag opening loses its fixation and falls onto the weighing plate 16 again, facilitating the staff to take the bag.

[0031] To facilitate controlling the lifting of the lifting assembly 17, as Figure 1 and Figure 2 shown, a driven bevel gear 1721 is fixedly connected to the lower end surface of the sleeve rod 172, and a driving bevel gear 1722 is engaged with the outer edge of the driven bevel gear 1721. A transmission shaft 1723 is fixedly connected to the inner cavity of the driving bevel gear 1722, and one end of the transmission shaft 1723 is fixedly connected to one side of the sleeve rod 172. By rotating the transmission shaft 1723 in the forward direction, the driving bevel gear 1722 rotates, driving the driven bevel gear 1721 to rotate. Then the driven bevel gear 1721 drives the sleeve rod 172 to rotate, causing the threaded rod 171 to move upward inside the sleeve rod 172, driving the weighing plate 16 to rise, and vice versa for descending, which is beneficial for adjusting the height between the weighing plate 16 and the ground.

[0032] Since the surface of the transmission shaft 1723 is relatively smooth and its diameter is small, it is inconvenient to hold and rotate by hand. Therefore, as Figure 1 and Figure 2 shown, a handle 1724 is fixedly connected to the end of the transmission shaft 1723 away from the sleeve rod 172. By rotating the handle 1724, the rotation of the transmission shaft 1723 is controlled, facilitating the control of the gear rotation.

[0033] When the flour quantitative weighing device of the utility model is specifically used, the flour bag mouth is sleeved on the top of the support port ring 14, the bag mouth is opened, and then the handle 1724 is rotated forward to drive the transmission shaft 1723 to drive the transmission bevel gear 1722 to rotate. The transmission bevel gear 1722 drives the driven bevel gear 1721 to rotate, and the driven bevel gear 1721 drives the sleeve rod 172 to rotate, so that the threaded rod 171 moves upward in the inner cavity of the sleeve rod 172, and then drives the weighing pan 16 to move upward, so that the bottom of the flour bag contacts the top of the weighing pan 16, so as to weigh the flour. Then, the flour is poured into the flour bag, and the value of the flour bag is observed. During the filling process, the gravity of the flour causes the weighing pan 16 to resist the lifting assembly 17 and slide downward, so that the pressing plate 11 presses the spring 161 at the bottom to slide downward in the chute on the top of the base 1. When the pressing plate 11 slides downward, it drives the pressing rods 12 on both sides of the top to move downward, so that the bottom of the pressing block 13 presses against the flour bag mouth on the top of the support port ring 14 to fix the bag mouth. At the same time, the rubber pad 131 between the pressing block 13 and the flour bag mouth is squeezed and undergoes compressive deformation, so that the rubber pad 131 can closely fit the surface of the bag mouth, increasing the friction force and further limiting the flour bag mouth to prevent the flour quality from increasing during the filling process and causing the bag mouth to fall off. After the flour is filled to the required weight, rotating the handle 1724 in the reverse direction can drive the weighing pan 16 to drop excessively, which is convenient for workers to carry the flour. At the moment when the weighing pan 16 drops, since the top of the flour bag mouth is fixed and will not move downward, the pressure on the top of the weighing pan 16 disappears, so that the pressure on the top of the pressing plate 11 disappears, and the spring 161 pushes the pressing plate 11 to rebound upward. Then, the pressing plate 11 pushes the pressing rod 12 to move upward, so that the bottom of the pressing block 13 disengages from the flour bag mouth on the top of the support port ring 14, and the flour bag mouth loses its fixation and falls onto the top of the weighing pan 16, which is convenient for the staff to take the bag.
