Description

Technical Field

[0001] This utility model relates to the field of double-headed screw packaging machines, specifically to a fully automatic double-headed screw protein powder quantitative packaging machine. Background Technology

[0002] Twin-screw packaging machines are widely used for quantitative packaging of powder and granular materials. They are characterized by high efficiency, precision, and stability, and are suitable for multiple industries such as chemical, food, pharmaceutical, and building materials.

[0003] Protein powder processing requires packaging machines to feed the cans. However, the clamping and quantitative filling processes lack automated and efficient devices, resulting in cumbersome and inefficient operation. Furthermore, the clamping mechanism lacks stability during movement; the clamps cannot move linearly, affecting clamping accuracy and reliability. Additionally, after filling, some protein powder tends to remain inside the discharge pipe. Current technology cannot automatically and effectively remove this retained protein powder, negatively impacting the discharge speed and reducing the overall quality and efficiency of the packaging operation. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a fully automatic double-headed screw-type quantitative packaging machine for protein powder. This invention solves the technical problem that existing technologies often result in some protein powder being retained inside the discharge pipe, and that existing technologies cannot automatically and effectively discharge all of this retained protein powder, thereby adversely affecting the discharge speed and reducing the overall quality and efficiency of the packaging operation.

[0005] The purpose of this utility model is achieved through the following means: a fully automatic double-head screw protein powder quantitative packaging machine, including a discharge mechanism and a load-bearing plate. The load-bearing plate is assembled at the bottom of the discharge pipe of the discharge mechanism. Clamping mechanisms are assembled on both the left and right sides of the upper end of the load-bearing plate. The clamping mechanism includes a cylinder. The output end of the cylinder is connected to a clamping plate. The inner cavity of the clamping mechanism is equipped with a discharge mechanism.

[0006] The discharge mechanism includes a hollow column, with a piston rod slidably connected to the inner cavity of the hollow column. The upper and lower ends of the hollow column are respectively connected to a first one-way valve pipe and a second one-way valve pipe. The piston rod is connected to a clamping plate. The top of the second one-way valve pipe is connected to a bend pipe, and the other end of the bend pipe is connected to a gas collecting pipe. The gas collecting pipe is connected to the outside of the discharge pipe of the discharge mechanism.

[0007] Furthermore, a weighing module is installed at the upper end of the discharge mechanism. The upper end of the weighing module is connected to a hopper, and the bottom of the hopper is connected to a discharge pipe. The inner cavity of the discharge mechanism is equipped with two screws, one large and one small. The large screw is responsible for rapid coarse feeding, and the small screw is responsible for slow fine feeding. The weighing module includes a weighing sensor and a weighing instrument, which are used to monitor the weight of the material in the packaging bag in real time and control the speed and stop of the screws to achieve the set packaging weight. The hopper is used to store the material to be packaged. At the same time, the discharge mechanism is also equipped with a frequency converter, a door-opening device, a dust removal system, an electrical cabinet, and a control system.

[0008] Furthermore, the hollow column is connected to a cylinder, which is welded to the upper end face of the load-bearing plate. The cylinder can support the hollow column and is fixed to the top of the load-bearing plate.

[0009] Furthermore, exhaust pipes are provided at both the upper and lower ends of the hollow column, and rubber rings are embedded in the inner cavity of the exhaust pipes. The exhaust pipes are used to expel the gas generated when the piston rod moves.

[0010] Furthermore, the clamp is externally connected to a clamp head, and a soft pad is embedded at the end of the clamp head away from the clamp. The clamp head is used to clamp and fix the packaging can, and avoids damaging the packaging can through its deformation capability.

[0011] Furthermore, a guide disc is embedded on the outside of the piston rod, and the guide disc is slidably connected to the inner cavity of the hollow column. The guide disc can guide the piston rod, so that the piston rod can move linearly within the inner cavity of the hollow column.

[0012] The beneficial effects of this utility model are:

[0013] The system automatically clamps and quantitatively fills the protein powder packaging cans using an added discharge mechanism, cylinder, and clamping plate. Simultaneously, the added hollow column and piston rod guide the clamping plate during the clamping mechanism's fixation of the packaging cans, ensuring linear movement and improving the overall stability of the clamping mechanism. Furthermore, the addition of a second one-way valve pipe, a first one-way valve pipe, a bend, and an air collection pipe automatically vents the discharge pipe when the discharge mechanism returns to its original position, completely expelling any protein powder residue inside. This prevents any protein powder from remaining inside the discharge pipe after filling, thus avoiding any impact on the discharge speed. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] For this embodiment, please refer to Figure 1 and Figure 2 The fully automatic double-head screw protein powder quantitative packaging machine specifically implemented includes a discharge mechanism 1 and a load-bearing plate 2. The load-bearing plate 2 is assembled at the bottom of the discharge pipe of the discharge mechanism 1. The upper left and right sides of the load-bearing plate 2 are equipped with clamping mechanisms 3. The clamping mechanism 3 includes a cylinder 31. The output end of the cylinder 31 is connected to a clamping plate 32. The inner cavity of the clamping mechanism 3 is equipped with a discharge mechanism 4.

[0021] The discharge mechanism 1 is a common double-headed screw packaging machine in the prior art, used to discharge protein powder in a quantitative manner. It works with the clamping mechanism 3 to automatically package and feed the packaging cans. The cylinder 31 is used to drive the clamping plate 32 to move. The clamping plate 32 is used to fix the packaging cans. The top of the discharge mechanism 1 is equipped with a control device, which is used to control the cylinder 31 and the discharge mechanism 1.

[0022] Please see Figure 3 and Figure 4 The discharge mechanism 4 includes a hollow column 41, with a piston rod 42 slidably connected to the inner cavity of the hollow column 41. The upper and lower ends of the hollow column 41 are respectively connected to a first one-way valve pipe 43 and a second one-way valve pipe 44. The piston rod 42 is connected to a clamping plate 32. The top of the second one-way valve pipe 44 is connected to a bend pipe 5, and the other end of the bend pipe 5 is connected to a gas collecting pipe 6. The gas collecting pipe 6 is connected to the outside of the discharge pipe of the discharge mechanism 1.

[0023] The second one-way valve pipe 44 can only exhaust air in one direction and cannot allow air to enter. The first one-way valve pipe 43 can only allow air to enter in one direction and cannot exhaust air. The bend pipe 5 is elastic and can be extended and retracted. The air collecting pipe 6 includes a hollow ring. The inner cavity of the hollow ring is uniformly connected with nozzles. The nozzles are inserted into the inner cavity of the discharge pipe and are designed at an angle.

[0024] The upper end of the discharge mechanism 1 is equipped with a weighing module 11, the upper end of which is connected to a hopper 12, and the bottom of the hopper 12 is connected to a discharge pipe. The inner cavity of the discharge mechanism 1 is equipped with two screws, one large and one small. The large screw is responsible for rapid coarse feeding, and the small screw is responsible for slow fine feeding. The weighing module 11 includes a weighing sensor and a weighing instrument, which are used to monitor the weight of the material in the packaging bag in real time and control the speed and stop of the screw to achieve the set packaging weight. The hopper 12 is used to store the material to be packaged. At the same time, the discharge mechanism 1 is also equipped with a frequency converter, a door-opening device, a dust removal system, an electrical cabinet, and a control system.

[0025] Hollow column 41 is connected to cylinder 31, which is welded to the upper end face of load-bearing plate 2. Cylinder 31 supports hollow column 41 and is fixed to the top of load-bearing plate 2. Exhaust pipes 45 are provided at both the upper and lower ends of hollow column 41. Rubber rings are embedded in the inner cavity of exhaust pipe 45. Exhaust pipe 45 is used to expel the gas generated when piston rod 42 moves.

[0026] The clamping plate 32 is externally connected to a clamp 33. A soft pad is embedded at the end of the clamp 33 away from the clamping plate 32. The clamp 33 is used to clamp and fix the packaging can. Through its deformation ability, it avoids damaging the packaging can. A guide plate is embedded on the outside of the piston rod 42. The guide plate is slidably connected to the inner cavity of the hollow column 41. The guide plate can guide the piston rod 42, so that the piston rod 42 moves linearly in the inner cavity of the hollow column 41.

[0027] When this solution is in operation, the protein powder packaging can is first placed on top of the load-bearing plate 2. The cylinder 31 is started to drive the clamping plate 32 and the clamping head 33 to move, thereby fixing the protein powder packaging can. The discharging mechanism 1 is started to feed the protein powder in a quantitative manner, thereby realizing the function of adding and packaging.

[0028] After the protein powder packaging can is filled, the discharge mechanism 1 is closed and the clamping mechanism 3 is activated to return to its original position. The return of the clamping plate 32 drives the piston rod 42 to move, which in turn generates airflow with the hollow column 41. The airflow passes through the second one-way valve pipe 44, the bend pipe 5, and the air collecting pipe 6, and enters the discharge pipe at the bottom of the discharge mechanism 1 to discharge all the protein powder retained inside the discharge pipe. This prevents some protein powder from remaining inside the discharge pipe after the discharge mechanism 1 has finished filling, which would affect the discharge speed.

[0029] The added discharge mechanism 1, cylinder 31, and clamping plate 32 automatically clamp and quantitatively fill the protein powder packaging can. Simultaneously, the added hollow column 41 and piston rod 42 automatically guide the clamping plate 32 during the clamping mechanism 3's clamping and fixing of the packaging can, causing the clamping plate 32 to move linearly, thereby improving the overall stability of the clamping mechanism 3's movement. Furthermore, the added second one-way valve pipe 44, first one-way valve pipe 43, bend pipe 5, and air collecting pipe 6 automatically vent the discharge pipe when the discharge mechanism 4 returns to its original position, completely discharging any protein powder remaining inside the discharge pipe. This prevents some protein powder from remaining inside the discharge pipe after the discharge mechanism 1 has finished filling, thus avoiding any impact on the discharge speed.

[0030] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
