Description

Technical Field

[0001] This invention relates to the field of chemical manufacturing technology, specifically to a controllable feeder for chemical raw materials with weighing function. Background Technology

[0002] Chemical production is an industrial process that transforms raw materials into valuable chemicals and materials through chemical reactions. This includes various operations such as synthesis, decomposition, polymerization, distillation, evaporation, and crystallization. Chemical products are widely used in daily life and industrial sectors, such as plastics, pharmaceuticals, fertilizers, coatings, and detergents.

[0003] In chemical production processes, machines are typically used to add materials in order to increase the efficiency of the filling process. However, existing filling devices usually require the materials to be weighed before the filling operation can be carried out. The segmented operation process increases production time and costs and is inconvenient. Therefore, a controllable chemical raw material filling machine with weighing function is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a controllable chemical raw material feeder with weighing function. It has the advantage of being able to conveniently complete the feeding operation after weighing, solving the problem that in the chemical production process, in order to increase the filling efficiency, machines are usually used for feeding. However, existing filling devices usually require weighing the material before feeding, and the segmented operation process increases production time costs and is inconvenient.

[0006] (II) Technical Solution

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A controllable chemical raw material feeder with weighing function includes a support column, a weighing frame fixedly installed on the top of the support column, a weighing plate rotatably connected to the inner side of the weighing frame, an ear block fixedly installed at the end of the weighing plate, a paper clamping component connected to the outer side of the ear block, an electric push rod fixedly installed on the outer side of the support column, a connecting plate fixedly connected to the output end of the electric push rod, a connecting sleeve fixedly installed on the top of the connecting plate, a spring fixedly installed on the top of the connecting sleeve, a push wheel fixedly connected to the other end of the spring, a shut-off switch fixedly installed on the outer side of the support column, and a striking component extending to the push wheel fixedly installed at the bottom of the connecting plate.

[0008] The beneficial effects of this invention are:

[0009] This controllable chemical raw material feeder with weighing function has the advantage of being able to conveniently complete the feeding operation after weighing.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the paper clamping component includes a paper clamping sleeve, and the inner side of the paper clamping sleeve is connected to a V-shaped spring piece that is pressed against the ear block.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the weighing paper can be easily clamped by the V-shaped spring, preventing contamination of the product as the material moves during the feeding process.

[0013] Furthermore, the weighing plate is tilted in its natural state, and the end of the weighing plate is L-shaped with the bent end in a horizontal state.

[0014] The advantage of adopting the above-mentioned further solution is that the horizontal position is used for weighing, which ensures the accuracy of the weighing.

[0015] Furthermore, a connecting groove is provided on the top of the weighing frame, and rotating bearing columns extending into the connecting groove are fixedly installed on both the front and rear sides of the weighing plate. A limiting rod extending into the connecting groove and in contact with the rotating bearing column is inserted into the outer side of the weighing frame.

[0016] The advantage of adopting the above-mentioned further solution is that the weighing plate can be removed by taking off the limiting rod, which facilitates maintenance.

[0017] Furthermore, a sliding groove is provided on the outer side of the support column, and a limiting block extending into the sliding groove is fixed at the end of the connecting plate. The support column and the connecting plate are slidably connected through the sliding groove and the limiting block.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation of the sliding groove and the limiting block, the movement of the connecting block can be made more stable, preventing twisting caused by the support of a single electric push rod.

[0019] Furthermore, a trigger plate is fixedly installed on the top of the connecting plate, and the trigger plate is located inside the top projection surface of the interrupting switch.

[0020] The advantage of adopting the above-mentioned further solution is that by triggering briefly, the cut-off switch is effectively triggered after the connecting plate moves, thereby stopping the operation of the electric push rod.

[0021] Furthermore, the moving distance of the connecting plate is greater than the horizontal distance between the top of the push wheel and the connection point between the weighing frame and the weighing plate.

[0022] The advantage of adopting the above-mentioned further solution is that this design ensures that the tilt direction of the weighing plate can be changed to another direction after the connecting plate is pushed.

[0023] Furthermore, the striking component includes a motor fixed to the bottom of the connecting plate, a rotating plate fixedly installed at the output end of the motor, an eccentric shaft fixedly installed on the other side of the rotating plate, a sliding rod extending to the bottom of the connecting plate slidably connected to the inner side of the connecting sleeve, and a transmission sleeve slidably connected to the end of the sliding rod.

[0024] The beneficial effect of adopting the above-mentioned further solution is that by striking the component, the sliding rod can repeatedly strike the push wheel, which facilitates shaking off the remaining raw materials.

[0025] Furthermore, a buffer pad that contacts the push wheel is fixed at the end of the sliding rod, a limiting groove is opened on the inner side of the connecting sleeve, and a limiting slider extending into the sliding groove is fixedly installed on the outside of the sliding rod.

[0026] The beneficial effect of adopting the above-mentioned further solution is that the setting of the limiting groove and the limiting slider can prevent the sliding rod from rotating, thereby preventing the transmission sleeve below it from deflecting and ensuring the reliability of the transmission.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, by Figure 1-5 The present invention provides a controllable feeder for chemical raw materials with weighing function. The invention includes a support column 1, a weighing frame 2 fixedly installed on the top of the support column 1, a weighing plate 3 rotatably connected to the inner side of the weighing frame 2, an ear block 4 fixedly installed at the end of the weighing plate 3, a paper clamping component 5 connected to the outer side of the ear block 4, an electric push rod 6 fixedly installed on the outer side of the support column 1, a connecting plate 7 fixedly connected to the output end of the electric push rod 6, a connecting sleeve 8 fixedly installed on the top of the connecting plate 7, a spring 9 fixedly installed on the top of the connecting sleeve 8, a push wheel 10 fixedly connected to the other end of the spring 9, a shut-off switch 11 fixedly installed on the outer side of the support column 1, and a striking component 12 extending to the push wheel 10 fixedly installed at the bottom of the connecting plate 7.

[0035] Furthermore, the paper clamping component 5 includes a paper clamping sleeve 51, and the inner side of the paper clamping sleeve 51 is connected to a V-shaped spring piece 52 that is pressed against the ear block 4.

[0036] When it is necessary to clamp the weighing paper, the paper clamp sleeve 51 can be removed directly. Then, the weighing paper can be inserted and clamped through the V-shaped spring piece 52. Then, the entire paper clamp sleeve 51 can be clamped through the ear block 4 to retain and hold the weighing paper.

[0037] Furthermore, the weighing plate 3 is tilted in its natural state, and the end of the weighing plate 3 is L-shaped with the bent end in a horizontal state.

[0038] Furthermore, a connecting groove is provided on the top of the weighing frame 2, and rotating bearing columns extending into the connecting groove are fixedly installed on both the front and rear sides of the weighing plate 3. A limiting rod extending into the connecting groove and in contact with the rotating bearing column is inserted into the outer side of the weighing frame 2.

[0039] Furthermore, a sliding groove is provided on the outer side of the support column 1, and a limiting block extending into the sliding groove is fixed at the end of the connecting plate 7. The support column 1 and the connecting plate 7 are slidably connected through the sliding groove and the limiting block.

[0040] Furthermore, a trigger plate is fixedly installed on the top of the connecting plate 7, and the trigger plate is located inside the top projection surface of the cut-off switch 11.

[0041] When the electric push rod 6 moves the connecting plate 7 upward, the trigger plate moves upward as well. When the trigger plate moves to the shut-off switch 11, the electric push rod 6 is stopped by the shut-off switch 11, thereby stopping the tilting.

[0042] Furthermore, the moving distance of the connecting plate 7 is greater than the horizontal distance between the top of the push wheel 10 and the connection point between the weighing frame 2 and the weighing plate 3.

[0043] Furthermore, the striking component 12 includes a motor 121 fixed to the bottom of the connecting plate 7. A rotating plate 122 is fixedly installed at the output end of the motor 121. An eccentric shaft 123 is fixedly installed on the other side of the rotating plate. A sliding rod 124 extending to the bottom of the connecting plate 7 is slidably connected to the inner side of the connecting sleeve 8. A transmission sleeve 125 that is slidably connected to the eccentric shaft 123 is fixedly connected to the end of the sliding rod 124.

[0044] Furthermore, a buffer pad that contacts the push wheel 10 is fixed at the end of the sliding rod 124, a limiting groove is opened on the inner side of the connecting sleeve 8, and a limiting slider extending into the sliding groove is fixedly installed on the outside of the sliding rod 124.

[0045] When the striking component is in operation, the motor 121 starts, thereby driving the rotating plate 122 on its front side to start rotating. At this time, the eccentric shaft 123 can rotate around the output shaft of the motor 121. Since there is a hole in the transmission sleeve 125 that can ensure that its left and right movement is not obstructed, it provides the power for the transmission sleeve 125 to move up and down. This allows the transmission sleeve 125 to move up and down repeatedly with the electric sliding rod 124, impacting the push wheel 10 and causing it to vibrate.

[0046] Working principle:

[0047] When weighing is required, the weighing paper can be laid out first through the paper clamping component 5, and then the chemical raw materials can be placed on the weighing plate 3. At this time, the weighing can be completed by the weighing frame 2. After the weighing is completed, the electric push rod 6 is started to push the weighing plate 3 to rotate. At this time, the chemical raw materials begin to slide down for feeding under the influence of gravity and the weighing plate 4 tilted to the other side.

[0048] After the electric push rod 6 moves to the trigger plate and triggers the shut-off switch 11, the striking component 12 starts to move and starts to strike the push wheel 10 above through the sliding rod 124, so that the push wheel 10 further strikes the symmetrical weighing plate 3 to complete the addition of residual material. When another chemical raw material needs to be added again, the weighing paper should be replaced first and then the process can be repeated.
