Description

Technical Field

[0001] This application relates to the field of filling technology, and in particular to a hardener filling system. Background Technology

[0002] Currently, hardeners (curing agents) are a class of key chemical materials used to promote resin curing. They have characteristics such as high viscosity, strong corrosiveness, and easy curing / crystallization. Hardeners are widely used in chemical, building materials, ink and coating fields.

[0003] Existing filling systems typically place the filling container below the filling head, manually adjust the container opening to be vertically aligned with the filling head, and then open the filling head to begin filling.

[0004] The existing technical solutions mentioned above have the following drawbacks: aligning the container with the filling head outlet manually relies entirely on the accuracy of the filling personnel's eyesight. However, some filling containers have small openings, and when the container opening is aligned with the filling head opening, deviations can easily occur, causing the hardener to spill outside the container during filling. Utility Model Content

[0005] This application provides a hardener filling system for precise filling of hardener.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A hardener filling system includes a filling platform, a feed hopper suspended above the filling platform, a measuring scale disposed on the surface of the filling platform and located below the feed hopper, and a fixing structure disposed on the surface of the measuring scale. A filling head is disposed at the lower end of the feed hopper, and a vertical discharge port is disposed at the lower end of the filling head and opposite to the surface of the measuring scale. The fixing structure includes two vertical mounting columns, a square sleeve horizontally disposed on the upper end of one of the mounting columns, a fixing rod slidably disposed within the square sleeve, and two fixing plates disposed at the upper end of the mounting column and the end of the fixing rod, respectively. The two fixing plates are disposed opposite each other, and the fixing plates are arc-shaped. The arc-shaped surfaces of the two fixing plates are coaxially disposed with the discharge port.

[0008] By adopting the above technical solution, and by setting up a filling platform, a feeding hopper, a measuring scale, and a fixing structure, the fixing structure includes a mounting column, a square sleeve, a fixing rod, and fixing plates. The curved surfaces of the two fixing plates are coaxial with the discharge port. The filling head at the lower end of the feeding hopper and the vertical discharge port at the lower end of the filling head, which is opposite to the surface of the measuring scale, allow the filling container to be placed on the measuring scale. The distance between the two curved fixing plates can be adjusted by sliding the fixing rod to clamp and fix the container, so that the container opening is precisely aligned with the discharge port. Compared with manually placing the filling container, the hardener is filled more accurately. At the same time, the weight of the hardener is monitored in real time during the filling process by the measuring scale, providing a structural basis for the accurate filling of the hardener.

[0009] Optionally, the feed hopper is formed by four metal plates arranged in a square pyramid shape.

[0010] By adopting the above technical solution, the feed hopper is formed by four metal plates forming a four-sided pyramid shape. The structural characteristics of the four-sided pyramid allow the hardener to flow towards the tip of the feed hopper under its own gravity. Furthermore, the inner wall formed by the four metal plates can reduce the retention of the hardener inside the feed hopper, facilitating the smooth entry of the hardener into the discharge pipe at the tip of the feed hopper and ensuring a smooth filling process.

[0011] Optionally, the tip of the feed hopper is provided with a discharge pipe, which communicates with the inside of the feed hopper. The filling head consists of a filling pipe, a connecting pipe inclined on the periphery of the filling pipe, and a cylinder. The end of the connecting pipe is connected to the end of the discharge pipe. Both the end face of the connecting pipe and the end face of the discharge pipe are coaxially provided with annular sealing plates. The surfaces of the sealing plates at the ends of the connecting pipe and the discharge pipe are sealed and fitted together, and fixed by a detachable chuck clamp.

[0012] By adopting the above technical solution, and by setting up a discharge pipe, a filling pipe, and a connecting pipe, with the end of the connecting pipe connected to the end of the discharge pipe, and both the end faces of the connecting pipe and the discharge pipe are coaxially equipped with annular sealing plates, and fixed by a detachable chuck clamp, a stable connection between the feed hopper and the filling head can be achieved. The annular sealing plate can enhance the sealing performance at the connection between the discharge pipe and the connecting pipe, reducing the risk of hardener leakage. The detachable chuck clamp can also provide convenience for the subsequent disassembly and maintenance of the filling head or the discharge pipe.

[0013] Optionally, the cylinder is located at the upper end of the filling tube. A sealing plate is connected to the outer wall of the cylinder via a connecting column. The cylinder piston rod passes through the sealing plate and is coaxially arranged with the sealing plate. A sealing plate is coaxially fixed to the upper end face of the filling tube. The cylinder is sealed to the upper end of the filling tube via the sealing plate and the chuck tube clamp. The end of the cylinder piston rod is located inside the filling tube. The lower end of the filling tube is closed. A circular connecting hole is coaxially opened on the lower end face of the filling tube. A ring-shaped sealing element is coaxially sleeved on the end of the cylinder piston rod. The corner of the sealing element near the closed end of the filling tube is machined into a conical shape. The conical surface of the sealing element is adapted to the connecting hole and can close the connecting hole.

[0014] By adopting the above technical solution, a cylinder is set up with the piston rod end located inside the filling tube. The lower end of the filling tube is closed and a circular connecting hole is coaxially opened on the lower end face. An annular seal is coaxially fitted on the piston rod end. By controlling the extension and retraction of the cylinder piston rod, the seal can be moved, thereby opening or closing the connecting hole at the lower end of the filling tube, thus controlling the start and stop of the hardener filling. At the same time, the cooperation of multiple sealing plates and seals can enhance the sealing performance at the connection between the filling tube and the cylinder and at the connecting hole, reducing hardener leakage.

[0015] Optionally, the seal is made of rubber.

[0016] By adopting the above technical solution and setting a rubber seal, the elastic properties of the rubber itself can be used to make the seal fit more tightly with the connecting hole at the lower end of the filling tube, further improving the sealing effect at the connecting hole and reducing the leakage of hardener from the gap in the connecting hole during the filling start and stop process.

[0017] Optionally, a display is provided on one side of the measuring scale, and the display is electrically connected to the measuring scale. The filling system also includes a controller, which is vertically arranged on one side of the feed hopper. The controller is electrically connected to the display and to a cylinder, and can control the piston rod of the cylinder to move along its axial direction.

[0018] By adopting the above technical solution and setting up a display and controller, the display can show the filling weight of the hardener monitored by the measuring scale in real time. The controller can control the piston rod of the cylinder to close the connecting hole when the weight fed back by the display reaches the set value, so as to realize the automatic quantitative filling of hardener and improve the efficiency and accuracy of the filling operation.

[0019] Optionally, each of the two fixed plates is equipped with a horizontally axial roller, the peripheral wall of which protrudes from the opposing surfaces of the two fixed plates.

[0020] By adopting the above technical solution and setting rollers, the rotation characteristics of the rollers will not hinder the vertical movement of the container when the filling container is clamped and fixed by two fixed plates, ensuring that the measuring scale can accurately measure the total weight of the container and hardener during the filling process and improve the accuracy of the measurement results.

[0021] Optionally, the two clamping plates of the chuck are recessed relative to each other, and the recessed clamping plates are adapted to the peripheral wall of the sealing sheet, so that the chuck fixes the two mating sealing sheets.

[0022] By adopting the above technical solution, and by setting two clamping plates with concave surfaces that fit the peripheral wall of the sealing sheet, the concave part of the chuck can be precisely fitted with the peripheral wall of the sealing sheet, making the chuck clamp more secure in fixing the two sealing sheets, further enhancing the sealing performance at the connection of the sealing sheets, and reducing the possibility of hardener leaking from the gaps between the sealing sheets.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a filling platform, a feeding hopper, a measuring scale, and a fixing structure, the fixing structure includes a mounting column, a square sleeve, a fixing rod, and fixing plates. The curved surfaces of the two fixing plates are coaxial with the discharge port. The filling head at the bottom of the feeding hopper and the vertical discharge port at the bottom of the filling head, which is opposite to the surface of the measuring scale, allow the filling container to be placed on the measuring scale. The distance between the two curved fixing plates can be adjusted by sliding the fixing rod to clamp and fix the container, so that the container opening is precisely aligned with the discharge port. Compared with manually placing the filling container, the hardener is filled more accurately. At the same time, the weight of the hardener is monitored in real time during the filling process by the measuring scale, providing a structural basis for the accurate filling of the hardener.

[0025] 2. By setting up a discharge pipe, a filling pipe, and a connecting pipe, with the end of the connecting pipe connected to the end of the discharge pipe, and both the end faces of the connecting pipe and the discharge pipe are coaxially equipped with annular sealing plates and fixed by a detachable chuck pipe clamp, a stable connection between the feed hopper and the filling head can be achieved. The annular sealing plate can enhance the sealing performance at the connection between the discharge pipe and the connecting pipe, reducing the risk of hardener leakage. The detachable chuck pipe clamp can also provide convenience for the subsequent disassembly and maintenance of the filling head or the discharge pipe.

[0026] 3. By setting up a display and a controller, the display can show the weight of the hardener being filled by the measuring scale in real time. The controller can control the piston rod of the cylinder to close the connecting hole when the weight fed back by the display reaches the preset filling weight, thereby realizing automatic quantitative filling of hardener and improving the efficiency and accuracy of the filling operation.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a hardener filling system, referring to... Figure 1 The filling system includes a filling platform, a feed hopper 2 located above the filling platform, a measuring scale 3 located below the feed hopper 2 on the filling platform, a controller 5 located above the filling platform, and a fixing structure 6 located on the surface of the measuring scale 3. The filling container is placed on the surface of the measuring scale 3, and the fixing structure 6 can quickly and accurately position the filling container, improving the accuracy of filling. The controller 5 can automatically fill the container according to the set weight and the measuring scale 3, improving efficiency.

[0032] Reference Figure 1 The filling platform consists of a horizontal square plate and four vertical square rods installed at the corners of the lower surface of the square plate. A mounting frame 11 is vertically installed on the filling platform surface. The mounting frame 11 consists of four vertical angle steels and horizontal angle steels connecting the vertical angle steels. The grooves of the four vertical angle steels are opposite each other to form a square column-shaped area. The horizontal angle steels are placed between adjacent vertical angle steels. The lower end of the mounting frame 11 is fixed to the filling platform surface and is close to one side wall of the filling platform.

[0033] Reference Figure 1 The feed hopper 2 is installed inside the mounting frame 11, spaced apart from the filling platform. The feed hopper 2 is a four-sided pyramid formed by four metal plates, with its flared opening facing vertically upwards. The upper surface of the feed hopper 2 is flush with the upper surface of the mounting frame 11. The upper ends of the four outer side walls of the feed hopper 2 are fixed to the horizontal angle steel of the mounting frame 11 located above. A discharge pipe 21 is provided at the tip of the feed hopper 2, which communicates with the interior of the feed hopper 2. The wall of the discharge pipe 21 is curved. The four-sided pyramid shape of the feed hopper 2 allows the hardener to flow towards the tip, reducing the possibility of the hardener remaining in the feed hopper 2.

[0034] Reference Figure 1A filling head 22 is provided at the end of the discharge pipe 21 away from the feed hopper 2. The filling head 22 consists of a filling pipe 221, a connecting pipe 222 inclined on the periphery of the filling pipe 221, and a cylinder 223. The end of the connecting pipe 222 is connected to the end of the discharge pipe 21. Both the end face of the connecting pipe 222 and the end face of the discharge pipe 21 are coaxially provided with annular sealing plates 211. The surface of the sealing plate 211 at the end of the connecting pipe 222 and the end of the discharge pipe 21 are sealed and fitted together, and fixed by a detachable chuck clamp 212. The two clamps of the chuck clamp 212 are recessed relative to each other. The recessed clamps are adapted to the periphery of the sealing plate 211. The chuck clamp 212 fixes the two fitted sealing plates 211.

[0035] Combination Figure 1 and Figure 2 The filling tube 221 is vertical, and the cylinder 223 is located at the upper end of the filling tube 221. A sealing plate 211 is connected to the outer wall of the cylinder 223 via a connecting column. The piston rod of the cylinder 223 passes through the sealing plate 211 and is coaxially arranged with it. The peripheral wall of the piston rod of the cylinder 223 slides and seals with the sealing plate 211. The sealing plate 211 is coaxially fixed to the upper end face of the filling tube 221. The cylinder 223 is sealed to the upper end of the filling tube 221 via the sealing plate 211 and the chuck clamp 212. The end of the piston rod of the cylinder 223 is located inside the filling tube 221.

[0036] Combination Figure 1 and Figure 2 The lower end of the filling tube 221 is closed, and a circular connecting hole is coaxially opened on the lower end face of the filling tube 221. A ring-shaped sealing element 224 is coaxially sleeved on the piston rod end of the cylinder 223. The sealing element 224 is made of rubber. The corner of the sealing element 224 near the closed end of the filling tube 221 is processed into a conical shape. The conical surface of the sealing element 224 is adapted to the connecting hole and can close the connecting hole.

[0037] Combination Figure 1 and Figure 2 A discharge port 225 is provided at the lower end of the filling tube 221. The discharge port 225 is coaxially arranged with the filling tube 221 and fixedly connected to the lower end of the filling tube 221. The inner diameter of the discharge port 225 is smaller than the diameter of the filling tube 221, which improves the accuracy of hardener filling. A measuring scale 3 is set inside the mounting frame 11. The surface of the measuring scale 3 is always opposite to the discharge port 225, and the measuring scale 3 can accurately measure the weight of the object located on the surface of the measuring scale 3. A display 4 is set on one side of the measuring scale 3. The display 4 is electrically connected to the measuring scale 3. The display 4 can digitally display the weight of the object measured by the measuring scale 3 and has functions such as tare, accumulation and zeroing. A controller 5 is vertically set on one side of the mounting frame 11 by an angle iron. The controller 5 is electrically connected to the display 4 and connected to the cylinder 223, and can control the piston rod of the cylinder 223 to move along its axial direction.

[0038] Reference Figure 1 The fixing structure 6 includes a mounting column 61, a square sleeve 62, a fixing rod 63, and a fixing plate 64. The mounting column 61 is vertically mounted on the surface of the measuring scale 3. Two mounting columns 61 are provided, spaced apart. The square sleeve 62 is located on the upper part of the mounting column 61 near the controller 5. The side wall of the square sleeve 62 is fixed to the upper surface of the mounting column 61. The length direction of the square sleeve 62 is perpendicular to the length direction of the mounting plate. The square sleeve 62 is suspended above the measuring scale 3 and closed at both ends. The fixing rod 63 is inserted into the square sleeve 62 and slidably disposed within it. The fixing rod 63 is cylindrical, and its length direction is parallel to the length direction of the square sleeve 62. An annular thickened portion is machined to the end of the peripheral wall of the fixing rod 63, located on the opposite side of the two mounting columns 61.

[0039] Reference Figure 1 A square limiting plate and a spring (not shown in the figure) are provided inside the square sleeve 62. The square limiting plate is sleeved on the peripheral wall of the fixing rod 63. The side wall of the square limiting plate is adapted to the inner wall of the square sleeve 62 and is slidably disposed in the square sleeve 62. The surface of the square limiting plate can fit against the inner wall end face of the square sleeve 62 away from the annular thickened part. The spring is disposed between the square limiting plate and the inner wall end face of the square sleeve 62. The spring is sleeved on the fixing rod 63. One end of the spring is fixed to the inner wall end face of the square sleeve 62 near the annular thickened part, and the other end is fixed to the surface of the square limiting plate.

[0040] Reference Figure 1 Two fixing plates 64 are provided, one on the upper end of the mounting post 61 near the controller 5 and the other on the end face of the fixing rod 63 away from the annular thickened part. The fixing plates 64 are arc-shaped, and the arc-shaped surfaces of both fixing plates 64 are coaxially arranged with the circular tube of the discharge port 225. The fixing plates 64 can fit against the peripheral wall of the filling container. The fixing structure 6 can fix the filling container placed on the measuring surface and make the opening of the filling container opposite to the discharge port 225. A horizontally axial roller is rotatably installed inside each of the two fixing plates 64. The peripheral wall of the roller protrudes from the opposing surfaces of the two fixing plates 64. The fixing plates 64 restrict the horizontal movement of the filling container, while the rollers allow the vertical movement of the filling container to be unrestricted, improving the measurement accuracy of the measuring scale 3.

[0041] Reference Figure 1During the filling process, firstly, the annular thickened part is pulled to move the movable fixing plate 64 away from the other fixing plate 64. The filling container is placed between the fixing plates 64, and the annular thickened cloth is loosened. The two fixing plates 64 clamp and fix the filling container, and make the opening of the filling container coaxial with the lower end of the discharge port 225. The controller 5 controls the piston rod of the cylinder 223 to move away from the measuring scale 3, so that the connecting hole of the filling tube 221 is opened, and the hardener is poured into the filling container. When the filling container is placed, the display 4 shows the weight of the hardener poured into the filling container in real time. The measuring scale 3 measures the weight of the hardener poured into the filling container in real time and displays it on the display 4 in real time. When the hardener reaches the weight set by the controller 5, the controller 5 controls the piston rod of the cylinder 223 to close the filling head 22, and the filling ends.
