Description

Technical Field

[0001] The utility model specifically relates to the technical field of material filling and weighing, and more specifically to an automatic weighing device for plant small molecule proteins. Background Art

[0002] Plant small molecule proteins refer to proteins with relatively small molecular weights, such as corn steep liquor dry powder and low red rice nutrient premix. Most of these materials are powders. After production, plant small molecule proteins need to be packed into packaging bags, and in order to ensure that the weight of each bag is consistent, weighing is also required during filling.

[0003] However, in practice, it has been noted that the height of the equipment discharge port is fixed, and the weighing equipment is located below the discharge port. When the packaging bag is short, after fixing the bag mouth, the bottom of the packaging bag cannot fit with the weighing component, and weighing cannot be completed. It is necessary to fill first and then weigh, and in order to meet the filling requirements, repeated filling and weighing are required, resulting in low efficiency; if the packaging bag is placed on the weighing component, the gap between the discharge port and the bag mouth easily causes the falling material to fall outside the packaging bag, resulting in waste. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatic weighing device for plant small molecule proteins, which adjusts the height between the lower part of the cylindrical cloth bag and the weighing tray for use with packaging bags of different heights. Then, tighten the bolts on the locking seat to make the locking seat approach the bracket until the locking seat and the bracket are closely attached to the outside of the vertical rod. It can realize the functions of filling and weighing packaging bags of different heights without changing the height of the discharge port, so as to solve the technical problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0029] Please refer to Figures 1-5 , the embodiments of the present utility model provide an automatic weighing device for plant small molecule proteins, including

[0030] A telescopic discharging assembly 5 for feeding packaging bags at different heights. The telescopic discharging assembly 5 includes an outer sleeve 51, and an annular protrusion 52 for fixing the bag mouth is integrally provided at the end of the outer sleeve 51 to prevent the bag mouth from slipping downward after being fixed;

[0031] A cylindrical cloth bag 53 for guiding the material penetrates through the inner side of the outer sleeve 51 to guide the falling material and prevent the material from falling outside the packaging bag. The end of the cylindrical cloth bag 53 is turned outwards and fixed to the end of the outer sleeve 51. A hoop piece 6 for locking with the discharging port is provided at the end of the cylindrical cloth bag 53 to fix the cylindrical cloth bag 53 to the outside of the discharging port, so that the material directly falls into the packaging bag;

[0032] Bracket 4, with a locking seat 3 for adjustment provided at the end of the bracket 4, facilitating the adjustment of the height of the telescopic discharging assembly 5. The telescopic discharging assembly 5 is located at one end of the inner side of the bracket 4 away from the locking seat 3, and cooperates with the cylindrical cloth bag 53 to achieve synchronous filling and weighing.

[0033] In this embodiment, a vertical rod 2 is fixed at one end of the upper part of the base 1 to increase the structural strength of the vertical rod 2. The cross-section of the vertical rod 2 is T-shaped, and the locking seat 3 and the bracket 4 are respectively located on both sides of the vertical rod 2.

[0034] Specifically, a T-shaped groove is provided inside the locking seat 3, and the side surface of the vertical rod 2 is attached to the inside of the T-shaped groove, playing a positioning role.

[0035] In this embodiment, bolts penetrate through both ends of the locking seat 3, and the end of the bolt is connected to one end of the bracket 4 close to the vertical rod 2, fixing the bracket 4 to the side surface of the vertical rod 2 through the bolts.

[0036] In this embodiment, a weighing tray 11 is provided on the upper part of the base 1, and a weight sensor for detecting weight is provided between the base 1 and the weighing tray 11 to weigh the filled material.

[0037] Specifically, the bag mouth lock 7 is mainly composed of four symmetrically arranged rotating rods, and the rotating rods are arranged in two as a group. A cylindrical rod is used to connect between each group of the rotating rods, and clamping pieces are provided at the ends of each group of the rotating rods.

[0038] In this embodiment, both ends of the clamping piece are fixedly connected to the end of the rotating rod, and the side of the clamping piece close to the outer sleeve 51 is arc-shaped, fixing the bag mouth of the packaging bag to the outside of the outer sleeve 51.

[0039] Specifically, a cylinder 8 for opening and closing is provided between the two groups of the rotating rods, and both ends of the cylinder 8 are respectively movably connected to the two groups of the rotating rods.

[0040] By adopting the above technical solution, place the device below the discharging port, then put the cylindrical cloth bag 53 on the outside of the discharging port, fix the cylindrical cloth bag 53 to the outside of the discharging port through the hoop piece 6, so that the material directly enters the inside of the cylindrical cloth bag 53 after falling from the discharging port. Then, according to the height of the packaging bag, move the bracket 4 up and down to adjust the height between the lower part of the cylindrical cloth bag 53 and the weighing tray 11 for use with packaging bags of different heights. Then tighten the bolts on the locking seat 3 to make the locking seat 3 approach the bracket 4 until the locking seat 3 and the bracket 4 are tightly attached to the outside of the vertical rod 2, and the functions of filling and weighing packaging bags of different heights can be achieved without changing the height of the discharging port.

[0041] In this embodiment, the bracket 4 is composed of a trapezoidal frame and a rectangular frame. The outer sleeve 51 penetrates through the rectangular frame inside the bracket 4, and the outer sleeve 51 is fixedly connected to the bracket 4.

[0042] In this embodiment, the clamping pieces are symmetrically arranged on both sides of the outer sleeve 51, and the clamping pieces are attached to the side surface of the outer sleeve 51 to squeeze and clamp both ends of the bag mouth.

[0043] In this embodiment, the end of the rotating rod is movably connected to both sides of the bracket 4 through a pin shaft.

[0044] In this embodiment, the clamping pieces are located above the annular protrusion 52. After the clamping pieces and the annular protrusion 52 are staggered, the bag mouth of the packaging bag is located in the gap between the clamping pieces and the annular protrusion 52, increasing the contact area, thereby preventing the bag mouth from slipping.

[0045] In this embodiment, a non-slip rubber pad is provided on the side of the clamping piece close to the outer sleeve 51, further increasing the clamping effect on the bag mouth.

[0046] In this embodiment, two cylinders 8 are provided, which are symmetrically distributed on both sides of the outer sleeve 51 respectively. Orifice plates are installed at both ends of the cylinder 8, and both ends of the cylindrical rod penetrate through the inside of the orifice plates.

[0047] Specifically, a weight display (not shown in the figure) is fixed to a section of the bracket 4 away from the locking seat 3, and the weight display is electrically connected to the weight sensor. As the material increases, the weight sensor generates an electrical signal after being affected, and the electrical signal is transmitted to the weight display through a wire. The circuit board inside the weight display converts the electrical signal and displays the converted weight on the display screen on the surface of the weight display.

[0048] The working principle of the utility model is as follows: When in use, first adjust the relative height between the support 4 and the weighing tray 11 according to the height of the packaging bag. At the same time, the height-adjusting support 4 drives the locking seat 3 to slide up and down on the outside of the vertical rod 2. Then tighten the bolt on the locking seat 3 to make the locking seat 3 approach the end of the vertical rod 2 until the vertical rod 2 and the locking seat 3 are closely attached to both sides of the vertical rod 2 to fix the position of the support 4. The air cylinder 8 pushes the clamping piece at the end of the bag mouth locking device 7 to open, and then put the bag mouth of the packaging bag on the outside of the outer sleeve 51 and extend to the upper part of the annular protrusion 52. The output rod of the air cylinder 8 drives two groups of symmetrically arranged rotating rods to approach the outer sleeve 51 through the movable connection between the hole plate and the cylindrical rod to clamp the bag mouth above the annular protrusion 52. The material flows out from the discharge port and is directly guided to the inside of the packaging bag through the cylindrical cloth bag 53. As the material inside the packaging bag increases, the packaging bag will exert a downward force on the weighing tray 11. After the weighing weight sensor at the bottom of the weighing tray 11 receives it, a signal is generated and transmitted to the display for display; the structure is simple, the operation is very convenient, and the labor intensity of workers is effectively reduced.
