Description

Technical Field

[0001] The utility model relates to the technical field of epoxy resin production, in particular to a material metering device for epoxy resin production. Background Art

[0002] Epoxy resin is a high molecular polymer, which refers to a general term for a class of polymers containing two or more epoxy groups in the molecule. It is mainly used in adhesives, coatings, electronic appliances, and other fields. During the production of epoxy resin products, it is necessary to process a certain proportion of each component material according to the formula through mixing, reaction and other processes to complete the production of epoxy resin products. Therefore, it is necessary to limit the amount of material added through a material metering device to avoid large differences in the proportions of each component material affecting the quality of the epoxy resin product.

[0003] An epoxy resin material metering device with application number 202321701744.7 relates to the field of epoxy resin production technology and includes: a material box, a first feed hopper, a first guide plate, a baffle, a gate assembly, a weight scale, a tray, a rotating assembly, a second guide plate, and a terminal outlet. A partition is provided in the material box, which separates the material box into a first box body and a second box body. The first feed hopper is connected to the first box body. The first guide plate is tilted and located directly below the first feed hopper. The baffle is connected to the lower end of the first guide plate. A discharge port is provided on the lower side of the baffle. The gate assembly is provided at the discharge port position. The weight scale is provided in the first box body. The rotating assembly is provided in the first box body. The lower end of the second guide plate is connected to the first box body. The side wall of the first box body is provided with a terminal outlet. The utility model realizes automatic metering of solid raw materials, solving the problem that current metering devices for epoxy resin production cannot meter and discharge solid raw materials.

[0004] However, this technical solution will encounter the following problems during actual use: First, the way the pallet rotates to unload makes the pallet contact the material box through an axis. Therefore, part of the weight of the material in the pallet will be transferred to the material box through the axis, and the other part of the weight will exert pressure on the weight scale, resulting in affected weighing accuracy, and then the quality of subsequent epoxy resin products is affected; Second, the sealing plate moves vertically up and down, and there may be material just below the sealing plate. Therefore, the sealing plate will press the material when it moves down. At this time, the material presses against the sealing plate, leaving a gap between the sealing plate and the first guide plate and the transition guide groove, which can easily cause some smaller materials to flow out through the gap at the bottom of the sealing plate, causing waste, or affecting the weighing accuracy. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a material metering device for epoxy resin production to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a material metering device for epoxy resin production, comprising a device body, a first motor mounted on the outer surface of the device body, and a baffle connected to the output end of the first motor, and a sealing strip fixed to the bottom of the baffle; a second motor mounted on one side of the outer surface of the device body, and a swing frame connected to the output end of the second motor, a guide groove being provided on the outer surface of the swing frame, a hopper being provided on one side inside the swing frame, and a guide block being fixed to the outer surface of the hopper.

[0007] By adopting the above technical solution, a motor drives the baffle and the sealing strip to rotate. The baffle adopts a rotating switch. Compared with the up and down sliding switch, the baffle can apply a push-back force to the material when it rotates and closes, thereby avoiding material jamming the main baffle and affecting the closing of the baffle. At the same time, the sealing strip increases the sealing between the baffle and the device body, reducing the occurrence of small material outflow; the hopper can slide up and down in the swing frame through the guide block and the guide groove, so the swing frame does not transmit pressure to the swing frame during the weighing process, so that the weighing device bears the pressure generated by the weight of all materials, thereby improving the weighing accuracy, and the second motor can drive the swing frame to rotate after starting, and then the swing frame transmits force to the hopper through the guide groove and the guide block, so that the hopper rotates with the swing frame to facilitate unloading after weighing.

[0008] Furthermore, the first motor and the second motor are both servo motors.

[0009] By adopting the above technical solution, the first motor and the second motor are both servo motors to facilitate the control of the rotation angle and rotation direction of the baffle and the swing frame, and the control accuracy is high.

[0010] Furthermore, the baffle is rotatably connected to the device body.

[0011] By adopting the above technical solution, the staff turns on the first motor and then the output end drives the baffle and the sealing strip to rotate upward. Then the solid material can flow out through the gap under the baffle and fall into the hopper.

[0012] Furthermore, the sealing strip is made of rubber material, and the sealing strip abuts against the device body.

[0013] By adopting the above technical solution, the output end of the first motor drives the baffle to reverse and cooperate with the sealing strip to seal the gap to prevent the material from continuing to flow out.

[0014] Furthermore, the swing frame is rotatably connected to the device body.

[0015] By adopting the above technical solution, the second motor starts to drive the swing frame to rotate, and then the swing frame transmits force to the hopper through the guide groove and guide block, so that the hopper rotates with the swing frame to pour out the material.

[0016] Furthermore, the guide block has a T-shaped cross section, and the hopper is slidably connected to the swing frame through the guide groove and the guide block.

[0017] By adopting the above technical solution, the hopper can slide up and down in the swing frame through the guide blocks and guide grooves, so the swing frame does not transmit pressure to the swing frame during the weighing process, so that the weighing device can bear the pressure generated by the weight of all materials, thereby improving the weighing accuracy.

[0018] Furthermore, there are two guide grooves and two guide blocks, and the two guide grooves and two guide blocks are mirror-imaged.

[0019] By adopting the above technical solution, by increasing the number of guide grooves and guide blocks, the contact surface of the structure is increased to improve the stability of the support and prevent the hopper from falling off from the swing frame.

[0020] Furthermore, a feed port is connected to one side of the top of the device body, a discharge port is opened below one side of the device body, a material guide plate is connected inside the device body, and a weighing device is installed on one side of the inside of the device body.

[0021] By adopting the above technical solution, the staff pours the solid material onto the guide plate through the feed port. When the weigher detects that the material in the hopper reaches a certain weight, the swing frame transmits force to the hopper through the guide groove and guide block, causing the hopper to rotate with the swing frame to pour out the material, and then the material is discharged through the discharge port.

[0022] Furthermore, the hopper abuts against the weighing device.

[0023] By adopting the above technical solution, the weighing device bears the pressure generated by the weight of all materials to weigh the materials, thereby facilitating the measurement of the materials.

[0024] Furthermore, a liquid storage cavity is provided below the interior of the device body, and a liquid guide plate is fixed below the interior of the liquid storage cavity. A liquid inlet pipe and a metering pump are respectively provided below the outer surface of the device body, and a liquid outlet pipe is connected between the metering pump and the liquid storage cavity.

[0025] By adopting the above technical solution, the staff inputs the liquid material into the liquid storage chamber through the liquid inlet pipe. The liquid storage chamber is located below the guide plate. The excess space below the guide plate is used to store the liquid material, reducing space waste to improve utilization rate. At the same time, the liquid material is guided to the liquid outlet pipe through the liquid guide plate. After that, the staff can start the metering pump to pump out the liquid material in a quantitative manner.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. The utility model adopts the arrangement of the second motor, the swing frame, the guide groove and the guide block. The hopper can slide up and down in the swing frame through the guide block and the guide groove. Therefore, the swing frame does not transmit pressure to the swing frame during the weighing process, so that the weighing device bears the pressure generated by the weight of all materials, thereby improving the weighing accuracy. After the second motor is started, it can drive the swing frame to rotate. Then, the swing frame transmits force to the hopper through the guide groove and the guide block, so that the hopper rotates with the swing frame to facilitate the discharge of materials after weighing; thus, interference is reduced to improve the weighing accuracy;

[0028] 2. The utility model is provided with a first motor, a baffle and a sealing strip. After the first motor is driven, the baffle and the sealing strip are driven to rotate. The baffle adopts a rotating switch method. Compared with the up and down sliding switch, the baffle can exert a push-back force on the material when it is rotated and closed, thereby avoiding the material getting stuck in the baffle and affecting the closing of the baffle. At the same time, the sealing strip is used to increase the sealing between the baffle and the device body, reducing the outflow of small materials; avoiding the phenomenon that the baffle is difficult to close completely due to the material blocking the baffle.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] Example 1:

[0038] A material metering device for epoxy resin production, such as Figure 1-Figure 5 As shown, it includes a device body 1, a first motor 12 is installed on the outer surface of the device body 1, and the first motor 12 is a servo motor, which is convenient for controlling the rotation angle and rotation direction of the baffle 13; the output end of the first motor 12 is connected to the baffle 13, the baffle 13 is rotatably connected to the device body 1, and a sealing strip 14 is fixed to the bottom of the baffle 13. The sealing strip 14 is made of rubber material and abuts against the device body 1. The output end of the first motor 12 drives the baffle 13 to reverse and cooperate with the sealing strip 14 to seal the gap to prevent the material from continuing to flow out;

[0039] A second motor 15 is installed on one side of the outer surface of the device body 1. The second motor 15 is a servo motor, which is convenient for controlling the rotation angle and rotation direction of the swing frame 16; the output end of the second motor 15 is connected to the swing frame 16, and the swing frame 16 is rotatably connected to the device body 1. The second motor 15 starts to drive the swing frame 16 to rotate, and then the swing frame 16 transmits force to the hopper 10 through the guide groove 17 and the guide block 18, so that the hopper 10 rotates with the swing frame 16 to pour out the material; the outer surface of the swing frame 16 is provided with a guide groove 17, and a hopper is provided on one side of the inner side of the swing frame 16. 10. A guide block 18 is fixed to the outer surface of the hopper 10, and the cross-section of the guide block 18 is "T"-shaped. The hopper 10 is slidably connected to the swing frame 16 through the guide groove 17 and the guide block 18. There are two guide grooves 17 and two guide blocks 18, and the two guide grooves 17 and the guide blocks 18 are mirror-imaged. The hopper 10 can slide up and down in the swing frame 16 through the guide block 18 and the guide groove 17. Therefore, the swing frame 16 does not transmit pressure to the swing frame 16 during the weighing process, so that the weighing device 9 bears the pressure generated by the weight of all materials, thereby improving the accuracy of weighing.

[0040] See Figure 1-Figure 3 In the above embodiment, a feed port 2 is connected to one side of the top of the device body 1, and the staff pours the solid material onto the guide plate 11 through the feed port 2; a discharge port 3 is opened at the lower side of the device body 1, and the hopper 10 rotates with the swing frame 16 to pour out the material, and then the material is discharged through the discharge port 3; a guide plate 11 is connected to the inside of the device body 1, and the solid material is guided to the baffle 13 through the guide plate 11; a weighing device 9 is installed on one side of the inside of the device body 1, and the hopper 10 is in contact with the weighing device 9. The weighing device 9 bears the pressure generated by the weight of all the materials to weigh and measure the materials.

[0041] Example 2:

[0042] In this technical solution, there is waste of space below the first guide plate, and the liquid metering structure needs to be provided with another chamber, resulting in reduced space utilization. On the basis of Example 1, in order to avoid and solve the above problem, the following settings are now adopted.

[0043] See Figure 1-Figure 3 In the above embodiment, a liquid storage chamber 7 is provided at the lower part of the device body 1. The liquid storage chamber 7 is located below the material guide plate 11. The extra space below the material guide plate 11 is used to store liquid materials, reducing space waste and improving utilization rate; a liquid guide plate 8 is fixed at the lower part of the liquid storage chamber 7, and the liquid material is guided to the liquid outlet pipe 5 through the liquid guide plate 8; a liquid inlet pipe 4 and a metering pump 6 are respectively provided at the lower part of the outer surface of the device body 1, and a liquid outlet pipe 5 is connected between the metering pump 6 and the liquid storage chamber 7. The staff inputs the liquid material into the liquid storage chamber 7 through the liquid inlet pipe 4, and then the staff can start the metering pump 6 to pump out the liquid material in a quantitative manner.

[0044] The implementation principle of the present utility model is as follows: first, the staff inputs the liquid material into the liquid storage chamber 7 through the liquid inlet pipe 4. The liquid storage chamber 7 is located below the guide plate 11. The excess space below the guide plate 11 is used to store the liquid material, reducing space waste and improving utilization rate. At the same time, the liquid material is guided to the liquid outlet pipe 5 through the liquid guide plate 8. After that, the staff can start the metering pump 6 to pump out the liquid material in a quantitative manner.

[0045] The staff pours the solid material onto the guide plate 11 through the feed inlet 2, and the solid material is guided to the baffle 13 by the guide plate 11. Then the staff turns on the first motor 12 and the output end drives the baffle 13 and the sealing strip 14 to rotate upward. Then the solid material can flow out through the gap below the baffle 13 and fall into the hopper 10. At the same time, the hopper 10 generates downward pressure due to the increase in the weight of the solid material entering. Since the hopper 10 can slide up and down in the swing frame 16 through the guide block 18 and the guide groove 17, the swing frame 16 does not transmit pressure to the swing frame 16 during the weighing process, so that the weighing device 9 bears the pressure generated by the weight of all materials, thereby improving the weighing accuracy.

[0046] When the material in the hopper 10 reaches a certain weight, the output end of the first motor 12 drives the baffle 13 to reverse and cooperate with the sealing strip 14 to seal the gap to prevent the material from continuing to flow out. At the same time, the second motor 15 starts to drive the swing frame 16 to rotate, and then the swing frame 16 transmits force to the hopper 10 through the guide groove 17 and the guide block 18, so that the hopper 10 rotates with the swing frame 16 to pour out the material, and then the material is discharged through the discharge port 3.

[0047] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
