Description

Technical Field

[0001] The utility model relates to the technical field of blanking hoppers, and particularly relates to a blanking hopper for deoxidizer production. Background Art

[0002] A deoxidizer, also known as an oxygen remover or oxygen absorber, is an additive that can absorb oxygen and slow down the oxidation of food. It is a new product being adopted in food preservation. It is a group of chemical mixtures that easily react with free oxygen or dissolved oxygen. Packed in a sealed paper bag with a certain air permeability and strength, like a desiccant bag, it is sealed and packaged with food in a food bag. It can remove the oxygen remaining in the air in the bag, prevent food from discoloring, deteriorating due to oxidation, and the rancidity of oils and fats. It also has an inhibitory effect on the growth of molds, aerobic bacteria, and grain pests. Deoxidizers are not only used to maintain the quality of food but also for the preservation and rust prevention of items such as grains, feeds, medicines, clothing, furs, and precision instruments.

[0003] Inside the traditional feeding hopper, the filtering of materials is only achieved through a fixedly arranged filter screen. Often, the filter screen becomes blocked by materials, resulting in the need to frequently stop the machine to remove the filter screen and clean the blocked materials on its upper part before continuing the blanking operation. This operation is troublesome and greatly reduces the blanking efficiency of the blanking hopper. Summary of the Utility Model

[0004] In view of this, the utility model provides a blanking hopper for deoxidizer production. When the upper filter plate becomes blocked, the synchronous opposite movement platform can drive the two filter plates to move in opposite directions, and at the same time, move the lower filter plate into the feeding hopper to continue the efficient screening and filtering operation of materials. The operation is more convenient and efficient, solving the problem that in the traditional feeding hopper, the filtering of materials is only achieved through a fixedly arranged filter screen, often resulting in the filter screen being blocked by materials, requiring frequent shutdowns to remove the filter screen and clean the blocked materials on its upper part before continuing the blanking operation, which is troublesome and greatly reduces the blanking efficiency of the blanking hopper.

[0005] To solve the above technical problems, the utility model provides a feeding hopper for deoxidizer production, which includes a support frame arranged on the frame of a conveyor. An inlet hopper is arranged on the support frame. A through groove is formed in the side wall of the inlet hopper. A synchronous moving platform moving towards each other is arranged in the through groove. Filter plates are respectively arranged on the upper and lower sides of the synchronous moving platform moving towards each other. A baffle plate in contact with the upper side wall of the filter plate is arranged on the inlet hopper and directly above the through groove. When the upper filter plate is blocked, the utility model can drive the two filter plates to move towards each other through the synchronous moving platform moving towards each other, and at the same time, move the lower filter plate into the interior of the inlet hopper to continue to realize the efficient screening and filtering operation of materials. The operation is more convenient and efficient, solving the problem that in the traditional inlet hopper, the filtering of materials is only achieved through a fixedly arranged filter net inside, and the filter net is often blocked by materials, resulting in frequent shutdowns to remove the filter net and clean the blocked materials on its upper part before continuing the feeding operation. The operation is troublesome and greatly reduces the feeding efficiency of the hopper. The screening effect is better, and the feeding efficiency of the inlet hopper is greatly improved.

[0006] The synchronous moving platform moving towards each other includes slide rails arranged in the through groove of the inlet hopper. Sliders with opposite threads are respectively arranged on the upper and lower sides of the slide rails. One of the sliders is fixedly arranged with the lower part of the upper filter plate, and the other slider is fixedly arranged with the upper part of the lower filter plate. Threaded through holes with opposite threads are formed on the axes of the two sliders. A left - right hand double - lead screw is threadedly connected in the threaded through holes of the two sliders. The other end of the left - right hand double - lead screw is provided with a motor. The utility model can drive the left - right hand double - lead screw to rotate through the rotation of the output shaft of the motor. Coupled with the threaded connection between the two sliders and the left - right hand double - lead screw and the guiding and limiting effects of the slide rails on the sliders, the rotation of the left - right hand double - lead screw can drive the two sliders threadedly connected to it and the filter plates thereon to move towards each other along the slide rails, thereby realizing the rapid switching of the upper and lower two filter plates only by briefly stopping the feeding. While enabling the feeding operation to proceed smoothly, it also does not affect the cleaning operation of the other blocked filter plate, and the operation is more convenient.

[0007] A limiting block is arranged inside the slide rail and between the two sliders. A through hole with a diameter larger than the outer thread diameter of the left - right hand double - lead screw is formed on the axis of the limiting block. The utility model can use the limiting block to block and limit the movement of the two sliders to prevent them from colliding with each other during the process of moving towards each other.

[0008] Multiple filter holes are formed on the filter plates, and the two filter plates are respectively located on both sides of the slide rail. The utility model can filter materials through the filter holes formed on the filter plates to avoid affecting subsequent production operations due to inconsistent particle sizes of the materials falling through the inlet hopper.

[0009] There are no filter holes on the filter plate directly above the slide rail, which can prevent the materials falling through the filter holes of the filter plate from spilling into the chute of the slide rail, resulting in jamming during the rotation of the double-threaded bidirectional screw.

[0010] Bellows covers are respectively arranged on the upper and lower sides of the slide rail. One end of the bellows cover is connected to the side wall of the slider, and the other end is connected to the end of the slide rail. The bellows cover can effectively block and protect the chute of the slide rail without affecting the movement operation of the slider carrying the filter plate.

[0011] Connecting plates fixedly arranged with the side walls of the feed hopper are respectively arranged on the front and rear side walls of the slide rail. Guide rails for supporting the filter plate and guiding its movement are arranged on the side walls of the feed hopper. The utility model can guide the movement of the filter plate through the guide rails and can also effectively support the filter plate, avoiding the filter plate from being bent or damaging the synchronous opposite-moving platform due to excessive impact force of the materials falling from the feed hopper.

[0012] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0013] 1. When the upper filter plate is blocked, the utility model can drive the two filter plates to move towards each other through the synchronous opposite-moving platform, and at the same time, move the lower filter plate into the feed hopper to continue the efficient screening and filtering operation of the materials. When the lower filter plate is blocked, just reverse-start the rotation of the output shaft of the motor, which can clean the blocked filter plate without affecting the operation of the filter holes, and the operation is more convenient and efficient. It solves the problem that the inside of the traditional feed hopper only uses a fixedly arranged filter screen to filter the materials, and often the materials block the filter screen, resulting in frequent shutdowns to remove the filter screen and clean the blocked materials on its upper part before continuing the feeding operation. The operation is troublesome and greatly reduces the feeding efficiency of the feed hopper. The screening effect is better and the feeding efficiency of the feed hopper is greatly improved.

[0014] 2. The utility model can drive the double-threaded bidirectional screw to rotate through the rotation of the output shaft of the motor. Coupled with the threaded connection between the two sliders and the double-threaded bidirectional screw and the guiding and limiting effects of the slide rail on the sliders, the rotation of the double-threaded bidirectional screw can drive the two sliders threaded thereon to drive the filter plates thereon to move towards each other along the slide rail, thereby realizing the quick switching of the upper and lower two filter plates only by briefly stopping the feeding. While the feeding operation can proceed smoothly, it also does not affect the cleaning operation of the other blocked filter plate, and the operation is more convenient.

[0015] 3. The utility model can block and limit the movement of the two sliders through the limit blocks, avoiding mutual collision during the process of moving towards each other.

[0016] 4. One end of the bellows shield is connected to the side wall of the slider, and the other end is connected to the end of the slide rail. Through the bellows shield, effective blocking and protection of the chute of the slide rail can be achieved, and it does not affect the movement operation of the slider with the filter plate. It can prevent the materials falling through the filter holes of the filter plate from spilling into the chute of the slide rail, resulting in jamming during the rotation of the double-threaded bidirectional lead screw.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the utility model clearer, the following will combine the accompanying drawings of the embodiments of the utility model Figures 1-5 , and clearly and completely describe the technical solutions of the embodiments of the utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the utility model. Based on the described embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the utility model.

[0024] Such as Figures 1-5As shown: This embodiment provides a feeding hopper for the production of deoxidizer, which includes a support frame 200 arranged on the frame of the conveyor 100. A feed hopper 300 is arranged on the support frame 200. A through groove 400 is opened on the side wall of the feed hopper 300. A synchronous moving platform 500 moving towards each other is arranged in the through groove 400. Filter plates 600 are respectively arranged on the upper and lower sides of the synchronous moving platform 500 moving towards each other. A baffle plate 700 in contact with the upper side wall of the filter plate 600 is arranged on the feed hopper 300 and directly above the through groove 400. When the upper filter plate 600 is blocked, the present utility model can drive the two filter plates 600 to move towards each other through the synchronous moving platform 500 moving towards each other, and at the same time, move the lower filter plate 600 into the interior of the feed hopper 300 to continue to achieve efficient screening and filtering operations on the material. The operation is more convenient and efficient, solving the problem that the interior of the traditional feed hopper 300 only filters the material through a fixedly arranged filter net, and often the material blocks the filter net, resulting in frequent shutdowns to remove the filter net and clean the blocked material on its upper part before continuing the feeding operation. The operation is troublesome and greatly reduces the feeding efficiency of the feeding hopper. The screening effect is better and the feeding efficiency of the feed hopper 300 is greatly improved.

[0025] According to an embodiment of the present utility model, as Figures 1-5 shown, the synchronous moving platform 500 moving towards each other includes slide rails 501 arranged in the through groove 400 of the feed hopper 300. Sliders 502 with opposite thread pitches are respectively and slidably arranged on the upper and lower sides of the slide rails 501. One of the sliders 502 is fixedly arranged with the lower part of the upper filter plate 600, and the other slider 502 is fixedly arranged with the upper part of the lower filter plate 600. Threaded through holes with opposite thread pitches are opened on the axes of the two sliders 502. A positive and negative thread bidirectional lead screw 503 is threadedly connected in the threaded through holes of the two sliders 502. The other end of the positive and negative thread bidirectional lead screw 503 is provided with a motor 504. The present utility model can drive the positive and negative thread bidirectional lead screw 503 to rotate through the rotation of the output shaft of the motor 504. Coupled with the threaded connection between the two sliders 502 and the positive and negative thread bidirectional screw and the guiding and limiting effects of the slide rails 501 on the sliders 502, the rotation of the positive and negative thread bidirectional lead screw 503 can drive the two sliders 502 threadedly connected thereto to drive the filter plates 600 thereon to move towards each other along the slide rails 501, thereby achieving a quick switch between the upper and lower two filter plates 600 only by briefly stopping the feeding. While enabling the feeding operation to proceed smoothly, it also does not affect the cleaning operation of the other blocked filter plate 600, and the operation is more convenient.

[0026] According to another embodiment of the present utility model, as Figure 1 and Figure 2As shown, a limiting block 505 is provided inside the sliding rail 501 and between two sliders 502. A through hole larger than the outer thread diameter of the double-threaded bidirectional lead screw 503 is provided on the axis of the limiting block 505. The present utility model can block and limit the movement of the two sliders 502 through the limiting block 505, avoiding mutual collision during their movement towards each other.

[0027] According to another embodiment of the present utility model, as Figure 1 and Figure 3 shown, a plurality of filter holes 601 are provided on the filter plate 600, and the two filter plates 600 are respectively located on both sides of the sliding rail 501. The present utility model can filter the material through the filter holes 601 provided on the filter plate 600, avoiding the influence on subsequent production operations caused by inconsistent particle sizes of the materials falling through the feed hopper 300.

[0028] According to another embodiment of the present utility model, as Figure 1 and Figure 5 shown, no filter holes 601 are provided on the filter plate 600 directly above the sliding rail 501, which can avoid the materials falling through the filter holes 601 of the filter plate 600 from spilling into the chute of the sliding rail 501, resulting in jamming of the rotation of the double-threaded bidirectional lead screw 503.

[0029] Bellows covers are respectively provided on the upper and lower sides of the sliding rail 501. One end of the bellows cover is connected to the side wall of the slider 502, and the other end is connected to the end of the sliding rail 501. The bellows cover can effectively block and protect the chute of the sliding rail 501 without affecting the movement operation of the slider 502 carrying the filter plate 600.

[0030] Connecting plates 800 fixedly provided with the side walls of the feed hopper 300 are respectively provided on the front and rear side walls of the sliding rail 501. Guide rails 900 for supporting the filter plate 600 and guiding its movement are provided on the side walls of the feed hopper 300. The present utility model can guide the movement of the filter plate 600 through the guide rails 900 and can also effectively support the filter plate 600, avoiding the filter plate 600 from being bent or damaged due to excessive impact force of the materials falling through the feed hopper 300 on the filter plate 600 and simultaneously damaging the synchronous moving platform 500 moving towards each other.

[0031] The usage method of the present utility model:

[0032] First of all, it should be clear that the discharging hopper involved in the present utility model is mainly used for screening operations during the discharging process of various bulk, powdery or granular materials. Taking the screening of deoxidizer during the discharging process as an example, the usage method of the present utility model is elaborated in detail. When it is necessary to perform the discharging operation on the deoxidizer, first, the deoxidizer to be discharged is introduced above the feeding hopper 300 through the conveying auger. At this time, the filter screen inside the feeding hopper 300 will perform the filtering and discharging operation on the deoxidizer. When the upper filter plate 600 is blocked, the output shaft of the motor 504 of the synchronous opposite moving platform 500 rotates to drive the upper filter plate 600 to move to the right, and at the same time, the lower filter plate 600 moves to the left, thereby realizing the opposite movement of the two filter plates 600 until the lower filter plate 600 is moved into the feeding hopper 300, and then the efficient screening and filtering operation of the material can be continued. When the lower filter plate 600 is blocked, reverse-start the output shaft of the motor 504 to rotate to drive the lower filter plate 600 to move to the left into the feeding hopper 300. This can clean the blocked filter plate 600 while not affecting the operation of the filter holes 601, and the operation is more convenient and efficient. The rotation of the output shaft of the motor 504 drives the left-right hand double lead screw 503 to rotate. Coupled with the threaded connection between the two sliders 502 and the left-right hand double lead screw and the guiding and limiting effects of the slide rail 501 on the sliders 502, the rotation of the left-right hand double lead screw 503 can drive the two sliders 502 threaded thereon to drive the filter plates 600 thereon to move in opposite directions along the slide rail 501, thereby realizing the rapid switching of the upper and lower two filter plates 600 only by briefly stopping the discharging. This enables the discharging operation to proceed smoothly while not affecting the cleaning operation of the other blocked filter plate 600, and the operation is more convenient, solving the problem that the filter of the traditional feeding hopper 300 only uses a fixedly arranged filter screen to filter the material, and often the material blocks the filter screen, resulting in frequent shutdowns to remove the filter screen and clean the blocked material on its upper part before the discharging operation can continue. The operation is troublesome and greatly reduces the discharging efficiency of the discharging hopper. The screening effect is better, and the discharging efficiency of the feeding hopper 300 is greatly improved.

[0033] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0034] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
