Description

Technical Field

[0001] This utility model relates to the field of rubber auxiliary material distribution technology, and in particular to an automated rubber batching production line. Background Technology

[0002] In the process of producing and processing rubber products, different auxiliary materials are often added to rubber granules to enable the rubber products to obtain the required properties. When mixing, workers need to scoop the auxiliary materials onto a weighing platform for weighing and then mix the quantitative amount of auxiliary materials together. When batching, workers need to accurately control the amount of auxiliary materials and also need to record the amount of auxiliary materials used frequently. The whole batching process is extremely cumbersome. Therefore, nowadays, most manufacturers have introduced automated batching equipment for batching.

[0003] While existing automated batching equipment can automatically discharge and record materials, some auxiliary materials carry dust, which escapes during the batching process, causing dust pollution within the factory. Therefore, there is a need for an automated batching device that can reduce dust emission and thus minimize dust pollution within the factory. Utility Model Content

[0004] The purpose of this utility model is to provide an automated rubber batching production line, which aims to solve the problem of dust flying during the preparation of materials.

[0005] To achieve the above objectives, this utility model provides an automated rubber batching production line, including a conveyor belt for transporting batching barrels. A batching mechanism is provided on the conveyor belt, which includes a frame, batching components, and a dust collection component. Multiple batching components and dust collection components are arranged in parallel on the frame, and the batching components and dust collection components correspond one-to-one.

[0006] The batching components all include a transfer hopper and a weighing conveyor belt. The dust collection components include a dust cover, a dust collection section, and a guide section. The transfer hopper and the dust cover are both fixedly installed on the frame. The transfer hopper is used to transport auxiliary materials to the weighing conveyor belt. The weighing conveyor belt is set inside the dust cover. A guide section is installed at the bottom of the dust cover. The guide section can cover the batching bucket on the conveyor belt. The discharge end of the weighing conveyor belt is located directly above the guide section. A dust collection section is installed on the dust cover. The dust collection section is used to absorb the scattered dusty auxiliary materials.

[0007] Furthermore, the vacuuming unit includes a vacuum hood, a filter element, and a vacuum fan. The vacuum hood is detachably installed on a dust cover. Multiple sets of air ducts are evenly arranged on the vacuum hood. Inside the vacuum hood are a primary filter chamber, a secondary filter chamber, and a fan chamber that are connected in sequence. The air ducts are connected to the primary filter chamber, and the fan chamber is used to install the vacuum fan. The filter element includes a primary filter element and a secondary filter element. The primary filter element is detachably installed in the primary filter chamber, and the secondary filter element is detachably installed in the secondary filter chamber. A detachable bottom cover is provided at the bottom of the vacuum hood.

[0008] Furthermore, the primary filter element includes a buffer layer and a coarse sponge layer, and the secondary filter element includes a fine sponge layer and an activated carbon layer; the dust cover is provided with an air inlet, and an air inlet filter element is installed at the air inlet.

[0009] Furthermore, the guide section includes a movable sleeve, a lifting drive component, and a pressure cap. The movable sleeve is installed at the bottom of the dust cover, and the pressure cap is installed at the bottom of the movable sleeve. The pressure cap can cover the mixing barrel. The lifting drive component is used to drive the pressure cap to rise or fall. Multiple sets of air supply grooves are evenly arranged at the bottom of the pressure cap. A funnel is provided at the center of the pressure cap, and the hopper can extend into the mixing barrel.

[0010] Furthermore, the bottom of the transfer hopper is equipped with a discharge pipe and a discharge drive unit. The discharge port of the discharge pipe is located above the weighing conveyor belt. A screw rod is installed in the discharge pipe, and the discharge drive unit is used to drive the screw rod to rotate and discharge the material.

[0011] Furthermore, the conveyor belt includes an internal conveyor belt and an external conveyor belt connected to each other. The internal conveyor belt is located below the batching mechanism, and the external conveyor belt is located outside the batching mechanism. A pusher drive is provided at the end of the internal conveyor belt, which is used to push the batching bucket on the internal conveyor belt onto the external conveyor belt.

[0012] Furthermore, a weighing component is installed on the internal conveyor belt, which is located directly below the guide section. The weighing component includes a lifting drive and a weighing platform. The lifting drive is fixedly installed at the bottom of the internal conveyor belt and is used to drive the weighing platform to rise or fall.

[0013] Furthermore, the batching mechanism also includes a main silo, which is equipped with a vacuum pump. The vacuum pump is used to pump the auxiliary materials in the main silo to the transfer silo. The main silo and the transfer silo correspond one-to-one.

[0014] Furthermore, the dust collection assembly also includes a fan, which is connected to multiple dust collection units via air ducts.

[0015] The automated rubber compounding production line provided by this utility model, compared with the prior art, has the following advantages: when compounding auxiliary materials, the internal conveyor belt transports the empty compounding bins to the bottom of the guide section, and the lifting drive drives the pressure cap to cover the compounding bins. Then, the feeding drive transfers the auxiliary materials in the transfer hopper to the weighing conveyor belt, which can measure the weight of the auxiliary materials. When the auxiliary materials reach the preset amount, the discharging drive stops, and the weighing conveyor belt transports the auxiliary materials to the guide section, where they fall into the compounding bins under the guidance of the guide section. The dust cover and guide section can prevent dust from flying. After the auxiliary materials are delivered to the compounding bins, the dust suction fan will absorb the dust floating in the guide section and dust cover into the filter element, avoiding dust pollution and affecting the health of the workers.

[0034] The present invention will be described in detail below with reference to specific embodiments.

[0035] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0036] like Figures 1 to 9 As shown, this utility model provides an automated rubber batching production line, including a conveyor belt 1 for transporting batching barrels 5. A batching mechanism 2 is provided on the conveyor belt 1. The batching mechanism 2 includes a frame, batching components 3 and dust collection components 4. Multiple batching components 3 and dust collection components 4 are arranged in parallel on the frame, and the batching components 3 and dust collection components 4 correspond one-to-one.

[0037] Each batching component 3 includes a transfer hopper 30 and a weighing conveyor belt 33. The dust collection component 4 includes a dust cover 40, a dust collection part 41, and a guide part 42. Both the transfer hopper 30 and the dust cover 40 are fixedly installed on the frame. The transfer hopper 30 is used to transport auxiliary materials to the weighing conveyor belt 33. The weighing conveyor belt 33 is set in the dust cover 40. The bottom of the dust cover 40 is equipped with a guide part 42, which can cover the batching bucket 5 on the conveyor belt 1. The discharge end of the weighing conveyor belt 33 is located directly above the guide part 42. The dust cover 40 is equipped with a dust collection part 41, which is used to absorb the scattered dust.

[0038] With the above design, workers can place the auxiliary materials to be mixed into the transfer silo 30. When auxiliary materials need to be mixed, the conveyor belt 1 transports the empty mixing bucket 5 to directly below the guide section 42. Then, the auxiliary materials in the transfer silo 30 are transported to the weighing conveyor belt 33. The weighing conveyor belt 33 can measure the weight of the auxiliary materials. When the auxiliary materials on the weighing conveyor belt 33 reach the preset value, the transfer silo 30 stops conveying, and the weighing conveyor belt 33 transports the weighed auxiliary materials into the mixing bucket 5. During the process of transferring powdered auxiliary materials from the transfer silo 30 to the weighing conveyor belt 33 or from the weighing conveyor belt 33 to the mixing bucket 5, some powder will escape. The dust cover 40 and the guide section 42 can limit the movement range of the dust and prevent the escaped dust from drifting into the factory. The dust collection unit 41 can absorb and collect the dust that escapes from the dust cover 40 and the guide section 42.

[0039] In this embodiment, the dust collection unit 41 includes a dust collection hood 410, a filter element, and a dust collection fan 412. The dust collection hood 410 is detachably installed on the dust cover 40. The dust collection hood 410 is evenly provided with multiple sets of air guide holes 411. The dust collection hood 410 is provided with a primary filter chamber, a secondary filter chamber, and a fan chamber that are connected in sequence. The air guide holes 411 are connected to the primary filter chamber, and the fan chamber is used to install the dust collection fan 412. The filter element includes a primary filter element 413 and a secondary filter element 414. The primary filter element 413 is detachably installed in the primary filter chamber, and the secondary filter element 414 is detachably installed in the secondary filter chamber. The bottom of the dust collection hood 410 is provided with a detachable bottom cover 415.

[0040] Through the above design scheme, the vacuum fan 412 can create a negative pressure zone inside the vacuum hood 410, allowing the airflow in the vacuum hood 410 to actively flow towards the vacuum hood 410. The airflow in the dust cover 40, mixed with scattered dust, enters the primary filter chamber through the air guide hole 411, where it is initially filtered by the primary filter element 413. After the initial filtration, the airflow passes through the secondary filter element 414, greatly reducing the dust content in the airflow output from the vacuum hood 410, thereby reducing the harm to workers caused by the airflow emitted into the factory.

[0041] In this embodiment, the primary filter element 413 includes a buffer layer 4130 and a coarse sponge layer 4131, and the secondary filter element 414 includes a fine sponge layer 4140 and an activated carbon layer 4141; the dust cover 40 is provided with an air inlet, and an air inlet filter element 43 is installed at the air inlet.

[0042] In this embodiment, the buffer layer 4130 is composed of vertical baffles arranged in an alternating pattern with gaps between them. When the airflow passes through the alternating baffles, most of the dust will be impacted by the baffles and then pass through the gaps between them. The dust impacted by the baffles will lose a lot of kinetic energy. When the airflow passes through the gaps, the dust with reduced kinetic energy will gradually fall until it falls into the bottom cover 415 of the dust hood 410 under the force of gravity. The remaining dust will be intercepted by the coarse sponge layer 4131, so that the dust content in the airflow passing through the primary filter 413 will decrease rapidly. The fine sponge layer 4140 and the activated carbon layer 4141 in the secondary filter 414 can further intercept the remaining small amount of dust in the airflow, so that the exhaust airflow will not affect the health of the staff.

[0043] In this embodiment, the guide part 42 includes a movable sleeve 420, a lifting drive 421, and a pressure cover 422. The movable sleeve 420 is installed at the bottom of the dust cover 40, and the pressure cover 422 is installed at the bottom of the movable sleeve 420. The pressure cover 422 can cover the mixing barrel 5. The lifting drive 421 is used to drive the pressure cover 422 to rise or fall. Multiple sets of air supply grooves 423 are evenly arranged at the bottom of the pressure cover 422. A funnel 424 is provided at the center of the pressure cover 422, and the hopper can extend into the mixing barrel 5.

[0044] Through the above design scheme, the movable sleeve 420 can ensure the sealing between the pressure cap 422 and the dust cover 40, and ensure that the dust cover 40 and the pressure cap 422 remain closed during the process of the lifting drive component 421 driving the pressure cap 422 to rise and fall; when the mixing barrel 5 is conveyed to the bottom of the pressure cap 422, the lifting drive component 421 drives the pressure cap 422 to press down and cover the mixing barrel 5, reducing the size of the gap above the mixing barrel 5, and ensuring that the floating powder is contained during the process of the auxiliary material being transferred from the weighing conveyor belt 33 to the mixing barrel 5. Dust is always confined inside by the pressure cap 422 and the movable sleeve 420 to prevent dust contamination. When the vacuum fan 412 is activated, external airflow can enter the interior of the pressure cap 422 through the air supply channel 423, and then flow back into the dust cover 40 along the movable sleeve 420, allowing the airborne dust to be drawn into the filter element. It should be understood that the vacuum fan 412 is in a closed state when the auxiliary materials are transferred from the weighing conveyor belt 33 to the mixing tank 5. After the delivery is completed, the vacuum fan 412 is activated to absorb the free dust. The negative pressure generated by the vacuum fan 412 should be at a level that can suck up the floating dust but will not suck up the auxiliary materials that have fallen into the weighing conveyor belt 33 and the mixing tank 5.

[0045] In this embodiment, the bottom of the transfer hopper 30 is provided with a discharge pipe 32 and a discharge drive 31. The discharge port of the discharge pipe 32 is located above the weighing conveyor belt 33. A screw rod is provided in the discharge pipe 32, and the discharge drive 31 is used to drive the screw rod to rotate and discharge the material.

[0046] Since the material conveying system consisting of the transfer hopper 30, the discharge drive unit 31 and the screw rod is existing technology and not an improvement point of this embodiment, it is not described in this embodiment.

[0047] In this embodiment, the conveyor belt includes an inner conveyor belt 10 and an outer conveyor belt 11 connected to each other. The inner conveyor belt 10 is located below the batching mechanism 2, and the outer conveyor belt 11 is located outside the batching mechanism 2. A pusher drive 12 is provided at the end of the inner conveyor belt 10. The pusher drive 12 is used to push the batching bucket 5 on the inner conveyor belt 10 onto the outer conveyor belt 11.

[0048] With the above design, the internal conveyor belt 10 is used to drive the mixing bucket 5 to move under the multiple mixing mechanisms 2. After it is filled with the required auxiliary materials, the mixing bucket 5 is guided by the internal conveyor belt 10 to the pusher drive 12. The pusher drive 12 pushes the mixing bucket 5 filled with auxiliary materials onto the external conveyor belt 11. The staff can directly remove the mixing bucket 5 filled with auxiliary materials and then place the empty mixing bucket 5 onto the external conveyor belt 11. The external conveyor belt 11 then transfers the empty mixing bucket 5 to the internal conveyor belt 10.

[0049] In this embodiment, a weighing component 6 is provided on the internal conveyor belt 10, and the weighing component 6 is located directly below the guide section 42. The weighing component 6 includes a lifting drive 60 and a weighing platform 61. The lifting drive 60 is fixedly installed at the bottom of the internal conveyor belt 10 and is used to drive the weighing platform 61 to rise or fall.

[0050] With the above design, when material needs to be unloaded, the mixing bucket 5 is transported down by the internal conveyor belt 10 to the weighing component 6. Then, the lifting drive 60 lifts the weighing platform 61 until it is separated from the internal conveyor belt 10, so that the weight of the mixing bucket 5 falls completely onto the weighing platform 61. The weighing platform 61 can perform secondary weighing on the auxiliary materials falling into the mixing bucket 5 to ensure that the auxiliary materials falling into the mixing bucket 5 meet the preset standards.

[0051] In this embodiment, each lifting drive unit 60 is provided with multiple sets of weighing platforms 61. The width of the weighing platform 61 is slightly smaller than the gap between the two sets of rollers, so that the weighing platform 61 can be raised between the two sets of rollers to lift the mixing barrel 5. The data of the multiple sets of weighing platforms 61 on each lifting drive unit 60 are interconnected, and the backend can determine the weight of the mixing barrel 5 and the auxiliary materials by reading the sum of the data of the weighing platform 61.

[0052] In this embodiment, the batching mechanism 2 also includes a main silo 20, on which a vacuum pump 21 is provided. The vacuum pump 21 is used to pump the auxiliary materials in the main silo 20 to the transfer silo 30. The main silo 20 and the transfer silo 30 correspond one-to-one.

[0053] With the above design, the main silo 20 can store a large amount of auxiliary materials. When the auxiliary materials in the intermediate silo 30 are depleted, the vacuum pump 21 on the main silo 20 can automatically replenish the auxiliary materials in the main silo 20 to the intermediate silo 30, so that the staff can replenish the auxiliary materials only once every long period of time.

[0054] In this embodiment, the dust collection assembly 4 further includes a fan 44, which is connected to multiple dust collection units 41 via an air duct 45. The fan 44 and the air duct 45 can guide the airflow output from the dust collection units 41 and discharge it to a specific area.

[0055] With the above design, during the batching operation, the external conveyor belt 11 transfers the empty batching bucket 5 to the internal conveyor belt 10, which then carries the batching bucket 5 past multiple batching components 3. In this embodiment, the internal conveyor belt 10 is equipped with multiple photoelectric limit switches, which are used to position the batching bucket 5 to ensure that it stops accurately directly below the pressure cap 422. Before the batching bucket 5 reaches below the pressure cap 422, the transfer hopper 30 pre-feeds the auxiliary materials to the weighing conveyor belt 33 to pre-weigh the required amount of auxiliary materials. When the mixing barrel 5 is moved directly under the pressure cap 422, the lifting drive 60 drives the weighing platform 61 to rise, so that the weight of the mixing barrel 5 falls completely onto the weighing platform 61; the lifting drive 421 controls the pressure cap 422 to press down and hold the mixing barrel 5. As the lifting drive 421 continues to press down, the data detected by the weighing platform 61 will also change. The back-end can clearly see whether the pressure cap 422 is pressing down on the mixing barrel 5. When the data detected by the weighing platform 61 changes continuously, the lifting drive 421 drives the pressure cap 422 to slowly rise until the data detected by the weighing platform 61 returns to zero. Then the lifting drive 421 continues to drive the pressure cap 422 to rise by 1-2 cm to avoid the pressure cap 422 affecting the measurement accuracy of the weighing platform 61. After the material guiding section is ready, the weighing conveyor belt 33 pours the pre-weighed auxiliary materials into the mixing bin 5. After pouring, the dust extraction fan 412 starts, sucking the dust from the dust cover 40 and the guide section 42 into the filter element. When the dust is almost absorbed, the lifting drive 421 drives the pressure cover 422 to rise, while the lifting drive 60 drives the weighing platform 61 to fall. The mixing bin 5 is then driven forward by the internal conveyor belt 10 to continue receiving another type of auxiliary material. It should be noted that the gap created after the lifting drive 421 raises the pressure cover 422 may cause a small amount of dust to escape. However, after the dust extraction fan 412 starts, the external airflow can guide the dust near the gap back into the guide section 42, reducing dust pollution.

[0056] After working for a certain period of time, the dust content in the primary filter 413 increases and the filtration effect decreases. The user can directly remove the vacuum unit 41 and use a vibrator to apply high-frequency vibration to the vacuum cover 410 to shake the dust in the primary filter 413 and the secondary filter 414 down. The falling dust collects on the bottom cover 415 for easy cleaning.

[0057] In this embodiment, the lifting drive component 421 and the pushing drive component 12 are preferably hydraulic rods.

[0058] The automated rubber compounding production line provided by this utility model, compared with the prior art, when compounding auxiliary materials, the internal conveyor belt 10 transports the empty compounding barrel 5 to the bottom of the guide section 42. The lifting drive 421 drives the pressure cover 422 to cover the compounding barrel 5. Then, the feeding drive transfers the auxiliary materials in the transfer hopper 30 to the weighing conveyor belt 33. The weighing conveyor belt 33 can measure the weight of the auxiliary materials. When the auxiliary materials reach the preset amount, the discharge drive 31 stops, and the weighing conveyor belt 33 transports the auxiliary materials to the guide section 42. Under the guidance of the guide section 42, the auxiliary materials fall into the compounding barrel 5. The dust cover 40 and the guide section 42 can prevent dust from flying. The dust suction fan 412 will absorb the dust floating in the guide section 42 and the dust cover 40 into the filter element to avoid dust pollution and affect the health of the workers.

[0059] Where there is no conflict, the above embodiments and features can be combined with each other.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
