Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to an intermediate material feeding structure for resin production. Background Art

[0002] Intermediates refer to semi-finished products, which are products produced in the middle of certain products. For example, if you want to produce a product, you can produce it from intermediates to save costs. For example, some small resin manufacturers directly purchase resin intermediate materials during production, and then add the intermediate materials during the operation of the reactor to prepare the resin.

[0003] When adding resin intermediate materials, a dust-free feeding station is required. This is a new type of feeding device. Through manual bag unloading and dumping, the material falls into the hopper by gravity to complete the bag unloading work. The equipment is equipped with filters, cleaning devices and exhaust fans to filter out the dust generated during the dumping process and discharge the clean exhaust gas into the atmosphere, allowing workers to work easily in a clean environment.

[0004] However, in the actual operation of the dust-free feeding station, in order to pour the material in the bag as quickly as possible after manually unpacking the bag, it is necessary to manually lift the rear end of the bag and shake the bag. This action consumes a lot of energy and can easily cause fatigue to the workers. Based on this, an intermediate material feeding structure for resin production is provided. Summary of the Invention

[0025] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 In an embodiment of the present invention, a structure for feeding intermediate materials for resin production includes a feeding assembly 1 consisting of a loading platform 101, a discharge port 102, a conical hopper 105, a dust cover 106, an exhaust fan 107, and a filter 108. The discharge port 102 is opened at the top of the loading platform 101 and passes through to the bottom of the loading platform 101. The conical hopper 105 is fixed to the bottom of the loading platform 101 and aligned with the discharge port 102. The dust cover 106 is fixed to the top of the loading platform 101 and is located outside the discharge port 102. The exhaust fan 107 is fixedly installed on the top of the dust cover 106. The filter 108 is installed on the top of the inner wall of the dust cover 106 and is aligned with the input end of the exhaust fan 107. The filter 108 is located above the discharge port 102. A receiving groove 103 is opened at the loading position on the top of the loading platform 101. The bottom of the receiving groove 103 is opened with a through slot 104 that passes through to the bottom of the loading platform 101.

[0027] An auxiliary material unloading assembly 2 is provided on the inner side of the receiving groove 103 and below the loading platform 101. The auxiliary material unloading assembly 2 is used to provide mobile support and lifting unloading operation for the material bag;

[0028] The auxiliary pouring assembly 2 includes a mobile support unit and a lifting unit;

[0029] The mobile support unit is used to provide support for the bag and reduce the movement resistance of the bag;

[0030] The lifting unit is used to drive the mobile support unit to flip, so as to lift the rear end of the bag to facilitate the pouring of the material;

[0031] The mobile support unit includes a turning bucket 201, a turning shaft 202, and a support roller 203;

[0032] The tilting bucket 201 is received in the inner side of the receiving groove 103. The tilting shaft 202 is symmetrically fixed to both sides of the outer wall of the front end of the tilting bucket 201 and penetrates the inner side of the inner wall of the receiving groove 103. The tilting bucket 201 is rotatably connected to the receiving groove 103 via the tilting shaft 202.

[0033] The support roller 203 is rotatably connected to the inner side of the tipping bucket 201. When the bag is placed on top of the support roller 203 and slides toward the discharge port 102, the rotation of the support roller 203 is used to reduce the movement resistance of the bag.

[0034] The lifting unit includes an L-shaped bracket 204 and a pneumatic push rod 205;

[0035] The L-shaped bracket 204 is symmetrically fixed on both sides of the inner wall of the through slot 104 and extends to the bottom of the loading platform 101. The bottom end of the shell of the pneumatic push rod 205 is rotatably connected to the middle of the two L-shaped brackets 204. The output end of the pneumatic push rod 205 passes through the through slot 104 and is rotatably connected to the bottom end of the tipping bucket 201. The pneumatic push rod 205 is driven to flip the tipping bucket 201 around the flipping axis 202, which is used to lift the rear end of the material bag so that the material can be dumped into the discharge port 102 faster.

[0036] In this embodiment, it should be noted that the dust cover 106 is open toward the turning platform 201 and a ventilation slot is provided on the top of the dust cover 106 that communicates with the inner cavity of the filter 108 and the air inlet of the exhaust fan 107.

[0037] When feeding the resin intermediate material, the material bag is manually transferred and placed on the support roller 203. The material bag can then be pushed to move closer to the discharge port 102. During this process, the support roller 203 rotates to reduce the movement resistance of the material bag, making this operation easier.

[0038] Then, the front end of the material bag is opened, and the material in the material bag slides to the discharge port 102 and falls into the interior of the conical hopper 105 (it should be noted that the conical hopper 105 is equipped with a corresponding conveying and feeding device (for example, a screw feeder) to convey the material into the reactor). At the same time, the exhaust fan 107 is started synchronously, and the exhaust fan 107 creates suction inside the dust cover 106 to prevent dust from escaping during the material dumping process;

[0039] In addition, after the front end of the material bag is opened, the pneumatic push rod 205 can be started synchronously (it should be noted that the pneumatic push rod 205 is started by the foot controller), and the pneumatic push rod 205 extends to push the tipping bucket 201 to flip upward, so that the material bag can be flipped into an inclined state as a whole, with the front end of the material bag facing downward (it should be noted that at this time, the operator's hand grasps the rear end of the material bag to prevent the material bag from sliding down). In this way, the material in the material bag can slide out faster, further improving the efficiency of material dumping;

[0040] Finally, the pneumatic push rod 205 drives the tipping bucket 201 to return to a horizontal state, and the single feeding operation is completed at this time. Through the cooperation of the above multiple parts, the dumping of materials can be made easier and more labor-saving, which can effectively reduce the work intensity of the staff.

[0041] Please refer to Figures 1 to 4 The receiving groove 103 is connected to the discharge port 102, and the tipping bucket 201 is open in the direction close to the discharge port 102.

[0042] In this embodiment: It should be noted that the portion of the receiving groove 103 near the discharge port 102 has sufficient depth and will not interfere with the turning operation of the tipping bucket 201. During the pouring process, some materials may fall into the inside of the tipping bucket 201. When the tipping bucket 201 is turned to an inclined state, this part of the material can slide through the opening of the tipping bucket 201 into the inside of the discharge chute 102.

[0043] Please refer to Figures 1 to 4 There are multiple support rollers 203 evenly arranged inside the tipping bucket 201, and the top level of the multiple support rollers 203 is lower than the level of the top of the edge of the tipping bucket 201, and the bottom of the support rollers 203 does not contact the bottom of the tipping bucket 201.

[0044] In this embodiment: the cooperation of multiple support rollers 203 can achieve support, movement guidance and resistance reduction of the material bag. This is because the top level of the multiple support rollers 203 is lower than the top level of the edge of the tipping bucket 201, which can prevent the material bag from moving out of the tipping bucket 201 area, thereby facilitating the subsequent tipping operation of the tipping bucket 201.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
