Description

Technical Field

[0001] This utility model relates to the field of material conveying and feeding technology, and in particular to an automatic sorting machine lifting and feeding device for rubber products. Background Technology

[0002] Before inspecting rubber products for dimensions, appearance, or weight, automatic sorting machines typically require a lifting feeding mechanism to continuously transport bulk workpieces from the lower storage area to the inspection channel. Existing lifting feeding mechanisms often employ an inclined conveyor belt combined with a storage trough. The feed end of the conveyor belt delves into the storage trough to pick up material, and transverse baffles are spaced along the width of the belt to improve its climbing capacity. However, due to the general characteristics of rubber products, such as irregular shape, softness and high elasticity, high surface friction coefficient and easy adhesion, the above structure still shows some shortcomings in practical applications: First, the effective support area of ​​the transverse partition for irregular parts is limited. When the conveying angle is large or the belt surface is affected by dust or oil, the workpiece is prone to slipping, rolling, or even falling from the sides, resulting in a high material loss rate. Moreover, it lacks the ability to guide the loose material to the center line along the belt width direction. When entering the detection area, the workpiece is laterally distributed and its posture is unstable, which easily leads to overlap and affects the accuracy of detection. Second, common straight-walled or simple inclined storage tanks are prone to bridging and agglomeration at the bottom of the tank under the action of stacking pressure and adhesion. This results in intermittent material feeding and pulsating material supply. It is common for the upstream to have empty belts and the downstream to have staged overfeeding. Existing devices generally lack a step to effectively pre-disperse and limit the layer thickness of the workpiece at the inlet. Adhesive or agglomerated workpieces are easily brought in as a whole, increasing the difficulty of subsequent separation and identification. Utility Model Content

[0003] The present invention aims to provide an upward feeding device for rubber products, in order to solve the problems of insufficient support, lack of central guidance, and easy adhesion of materials when the existing inclined conveyor belt with transverse partition is used to process irregularly shaped and easily adhered rubber parts, which affects the detection and identification of the sorting machine.

[0004] The technical solution of this utility model is as follows: An automatic sorting machine for rubber products with a lifting and feeding device, comprising: a housing; a support, including a housing support and a storage tank support; a storage tank, disposed on one side of the housing and mounted on the storage tank support; a transparent plate, mounted on the housing; a conveyor belt, inclinedly disposed on the housing support, with a closed loop formed between a drive pulley and a driven pulley disposed opposite to the housing support, the conveyor belt extending into one side of the storage tank as a feeding end; and a rotating wheel, disposed in the storage tank directly opposite the feeding end.

[0005] Furthermore, according to the aforementioned automatic sorting machine lifting feeding device for rubber products, the bottom of the storage tank is an integrally formed folded structure, and its fold line extends obliquely from the far inner corner to the side near the discharge end.

[0006] Preferably, the aforementioned automatic sorting machine lifting and feeding device for rubber products further includes: a first motor and a second motor, wherein the first motor is disposed on one side of the housing and connected to the drive pulley on the conveyor belt, and the second motor is disposed on one side of the storage tank and connected to the rotary wheel.

[0007] Preferably, in some embodiments, according to the aforementioned automatic sorting machine lifting and feeding device for rubber products, a fixing device is provided on the opposite side of the No. 1 motor and the No. 2 motor, and the fixing device includes a mounting base and a bearing.

[0008] Preferably, according to the aforementioned automatic sorting machine lifting and feeding device for rubber products, the conveyor belt has V-shaped material support ribs sequentially arranged on its circumferential edge surface.

[0009] Preferably, according to the aforementioned automatic sorting machine lifting and feeding device for rubber products, the outer circumferential surface of the rotary wheel is provided with V-shaped material-pushing ribs.

[0010] The beneficial effects of this utility model are as follows: By setting V-shaped material-supporting ribs on the conveyor belt conveyor surface to form a holding and wedge-shaped friction, the climbing support and anti-slip ability of the ascending section is significantly improved, reducing backslip and spillage on both sides. Combined with the integrally formed folded storage trough at the bottom, the loose material is redirected and slid to the feeding end, reducing the risk of stagnation and bridging at the bottom of the trough. A rotating wheel with V-shaped material-pushing ribs is set in the storage trough and, together with the feeding end of the conveyor belt, agitates, shears, and pre-disperses the accumulated material, reducing adhesion and agglomeration. The device is composed of common components such as a shell, support, storage trough, conveyor belt, and rotating wheel, with a clear structure, convenient manufacturing, assembly, and maintenance, facilitating its application on existing equipment.

[0012] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0013] Before inspecting rubber products for dimensions, appearance, or weight, automatic sorting machines typically require a lifting feeding mechanism to continuously transport bulk workpieces from the lower storage area to the inspection channel. Existing lifting feeding mechanisms often employ an inclined conveyor belt 7 in conjunction with a storage trough 3. The feed end of the conveyor belt 7 delves into the storage trough 3 to pick up material, and transverse baffles are spaced along the width of the belt surface to improve its climbing capacity. However, due to the general characteristics of rubber products, such as irregular shape, softness and high elasticity, high surface friction coefficient and easy adhesion, the above structure still shows some shortcomings in practical applications: First, the effective support area of ​​the transverse partition for irregular parts is limited. When the conveying angle is large or the belt surface is affected by dust or oil, the workpiece is prone to slipping, rolling, or even falling from the sides, resulting in a high material loss rate. Moreover, it lacks the ability to guide the loose material to the center line along the belt width direction. When entering the detection area, the workpiece is laterally distributed and its posture is unstable, which easily leads to overlapping and affects the accuracy of detection. Second, common straight-walled or simple inclined storage tanks 3 are prone to bridging and agglomeration at the bottom of the tank under the action of stacking pressure and adhesion. The material is discontinuous and the supply is pulsating. There are often situations where there is an empty belt upstream and a staged oversupply downstream. Existing devices generally lack a link to effectively pre-disperse and limit the layer thickness of the workpiece at the inlet. Adhesive or agglomerated workpieces are easily brought in as a whole, increasing the difficulty of subsequent separation and identification.

[0014] The present invention aims to provide a lifting feeding device for rubber products, in order to solve the problems of insufficient support, lack of central guidance, and easy adhesion of materials when the existing inclined conveyor belt 7 with transverse partitions is used to process irregularly shaped and easily adhered rubber parts, which affects the detection and identification of the sorting machine.

[0015] This embodiment discloses an automatic sorting machine lifting and feeding device for rubber products, including: a housing 1; a support, including a housing support 11 and a storage tank support 31; a storage tank 3, disposed on one side of the housing 1 and mounted on the storage tank support 31; a transparent plate 2, mounted on the housing 1; a conveyor belt 7, inclinedly disposed on the housing support 11, forming a closed loop belt between the drive pulley 41 and the driven pulley 42 disposed opposite to each other on the housing support 11, the conveyor belt 7 extending into one side of the storage tank 3 as the feeding end; and a rotating wheel 61, disposed in the storage tank 3 directly opposite the feeding end.

[0016] It is understood that in this embodiment, the closed loop belt refers to the continuous loop structure formed by the conveyor belt 7 winding around the drive pulley 41 and the driven pulley 42 that are disposed opposite to each other on the housing support 11.

[0017] The feeding end refers to the material-picking area of ​​the conveyor belt 7 near the storage trough 3, which is the material-picking area formed by the downward section of the conveyor belt 7 or its extension extending into the opening of the storage trough 3. The effective material-dispensing area of ​​the roller 61 corresponds to and is opposite to the feeding end. In use, bulk rubber products are put into the storage trough 3 and, under their own weight, converge towards the bottom of the trough and the side near the conveyor belt 7. The roller 61 rotates in the storage trough 3 to disturb the material and push it to the feeding end area. The conveyor belt 7 runs upward at a set speed driven by the drive pulley 41. The feeding end picks up the rubber parts close to the belt surface and conveys them upward with the conveyor belt 7 to the detection station of the sorting machine.

[0018] The transparent plate 2 is used for observation and maintenance, facilitating the confirmation of the material status in the tank, the relative position of the roller 61 and the feed end, and the material carrying status of the conveyor belt 7 without removing the cover. The above structure provides upward conveying force through the inclined conveyor belt 7, and achieves smooth transfer of material in the tank to the belt surface through the spatial alignment of the feed end and the roller 61. Stable and continuous feeding is formed by the continuous operation of the closed loop belt. Since the roller 61 is located in the storage tank 3 and is opposite to the feed end, it can disturb and push the accumulated material near the picking position, making it easier for the material to enter the picking area of ​​the conveyor belt 7, thereby reducing feeding pulsation and improving the feeding stability of the inspection section. The whole device is composed of common components such as the shell 1, support, storage tank 3, conveyor belt 7 and roller 61, which are easy to manufacture and assemble, and can be easily integrated into existing automatic sorting lines.

[0019] In some embodiments, the bottom of the storage tank 3 is an integrally formed folded structure, with the fold line extending obliquely from the far inner corner to the side near the discharge end.

[0020] It is understandable that the bottom of the storage tank 3 is set as an integrally formed folded structure. The folded surface is formed by directly pressing or molding the same base plate or the same molding part. The two sides are connected by a fold line. The fold line extends diagonally from the inner corner of the far side of the storage tank 3 to the side near the discharge end, so that the bottom forms a high and low partition and forms a guide slope towards the discharge end in space.

[0021] The far inner angle refers to the inner corner of the trough that is further away from the discharge end, and the "side closer to the discharge end" refers to the bottom area facing the discharge direction of the conveyor belt 7.

[0022] During operation, bulk rubber products fall into the storage tank 3 and, under their own weight, come into contact with the folded surface. A component force is generated along the folded surface pointing towards the discharge end and converges towards the area near the feed end along the fold line, avoiding diagonal bridging and stagnation at the bottom of traditional horizontal or symmetrical inclined surfaces. The intersection of the folded surface and the side wall is preferably set as a rounded transition to reduce obstruction. The inclination angle of the folded surface can be adjusted within a certain range according to the size, weight, and surface friction characteristics of the rubber products. Wear-resistant or low-friction coatings can be set on the folded surface to stabilize the sliding. Under this guiding effect, the material near the feed end is continuously replenished with a thin layer. The roller 61 pushes and pushes the material to the conveyor belt 7 at the feed position. The V-shaped material support ribs 71 on the conveyor belt 7 hold and convey the material upwards. Thus, without changing the overall external dimensions of the storage tank 3, the material is directionally gathered, the agglomeration at the bottom of the tank and the intermittent material feeding are suppressed, the feeding pulsation is reduced, and the feeding stability at the inspection station is improved.

[0023] In some embodiments, a first motor 4 and a second motor 6 are provided. The first motor 4 is located on one side of the housing 1 and is connected to the drive pulley 41 on the conveyor belt 7. The second motor 6 is located on one side of the storage tank 3 and is connected to the turntable 61.

[0024] It is understood that motor 4 is located on one side of housing 1 and connected to drive pulley 41. Drive pulley 41 drives conveyor belt 7 to form a closed loop and continuously move upward in a set direction. The feeding end thereby completes the picking up and feeding of materials close to the belt surface. Motor 6 is located on one side of storage tank 3 and connected to impeller 61. Impeller 61 continuously agitates and pushes the material in storage tank 3 near the feeding end, so that the material smoothly enters the picking area formed by conveyor belt 7 at the feeding end.

[0025] Preferably, the first motor 4 and the second motor 6 are set to different speeds so that the rotating wheel 61 and the conveyor belt 7 form a non-zero relative speed at the feeding position. This pre-disperses the material at the feeding end and avoids feeding pulsations caused by overfeeding or empty belts. During operation, the first motor 4 drives the drive pulley 41 to rotate, and the conveyor belt 7 reliably supports and conveys the material under the holding and guiding action of the V-shaped material-supporting ribs 71. The second motor 6 drives the rotating wheel 61 to rotate, and the V-shaped material-pushing ribs 611 on the outer periphery of the rotating wheel 61 push and shear the material near the feeding end and press it against the belt surface. This makes it easier for the material to be picked up at the feeding end and enter the pocket formed by the V-shaped material-supporting ribs 71. This reduces the probability of sticking and agglomerating while maintaining continuous feeding and improves the stability of the posture when entering the inspection station.

[0026] In some embodiments, a fixing device 5 is provided on the opposite side of motor 4 and motor 6. The fixing device 5 includes a mounting base and a bearing.

[0027] It is understandable that fixing devices 5 are respectively set on the opposite side of motor 4 and motor 6. Fixing devices 5 consist of mounting bases and bearings.

[0028] The mounting base is firmly connected to the housing bracket 11 or the storage tank bracket 31 to position and support the bearing. The bearing is installed in the hole of the mounting base and rotates with the shaft end of the drive pulley 41 and the rotating wheel 61, thereby forming a double-end support structure on the motor side and the fixed device 5 side. This ensures that the drive pulley 41 and the rotating wheel 61 maintain coaxiality and end face clearance stability during operation, reduces sway, vibration and noise, and ensures the relative position accuracy of the rotating wheel 61 and the feed end of the conveyor belt 7. Preferably, the mounting base is connected to the housing bracket 11 or the storage tank bracket 31 by fasteners, and can be provided with an elongated hole to achieve fine adjustment for calibrating the axis or setting the tension of the conveyor belt 7; the bearing can be a conventional part such as a deep groove ball bearing or a needle roller bearing, and if necessary, a positioning sleeve or a preload shim can be provided between the mounting base and the outer ring of the bearing to obtain a suitable interference fit and preload force; under the action of the above structure, the drive pulley 41 obtains stable support and transmission accuracy, and the disturbance and pushing of the roller 61 at the feeding position are more uniform. With the cooperation of the conveyor belt 7 and the V-shaped material support rib 71, continuous, stable, thin and central feeding is achieved, thereby improving the posture stability and cycle consistency when entering the inspection station, and facilitating maintenance and replacement.

[0029] In some embodiments, V-shaped material support ribs 71 are sequentially provided on the upper edge of the conveyor belt 7.

[0030] It is understood that V-shaped material-supporting ribs 71 are sequentially arranged on the belt surface of the conveyor belt 7 along the belt length direction. The V-shaped material-supporting ribs 71 are herringbone-shaped ribs raised on the belt surface, arranged with the center line of the conveyor belt 7 as the axis of symmetry. The V-shaped opening faces the feeding end and the tip faces the discharging direction. It is preferred to achieve this by integral molding and vulcanization with the conveyor belt 7 or by fixing it to the belt surface. The V-shaped included angle, rib height and pitch can be selected according to the size and weight range of the rubber product, so that adjacent V-shaped material-supporting ribs 71 form a continuous holding pocket on the belt surface.

[0031] During operation, the conveyor belt 7 moves upward under the drive pulley 41. Loose material near the feed end is picked up by the belt surface and falls into the "pocket" formed by the V-shaped material-supporting ribs 71. The two inclined sides of the V-shape generate wedge friction and lateral force on the workpiece, reliably supporting the loose material and converging it along the belt width to the centerline, thus significantly suppressing slippage and spillage on both sides during the upward section. The continuous arrangement of adjacent pockets allows the material to be stably fed upward with the conveyor belt 7 in a thin and uniform layer, which helps maintain the consistency of posture and cycle stability when entering subsequent workstations. The above structure can achieve the three functions of support, anti-slip and self-guiding on the surface of the conveyor belt 7 without adding any new parts, and can take into account the holding capacity and passage of rubber products of different specifications, improving the reliability and adaptability of upward feeding.

[0032] In this embodiment, the outer circumferential surface of the roller 61 is provided with V-shaped feeding ribs 611. The V-shaped feeding ribs 611 are arranged at intervals or slightly spirally along the axial direction of the roller 61, with the V-shaped opening facing the material receiving side. The height, pitch and included angle of the ribs can be determined according to the size and surface friction characteristics of the conveyed rubber product. It is preferable to use elastic rubber coating to reduce the impact on the workpiece while providing sufficient friction and shear.

[0033] During operation, the impeller 61, driven by motor 6, forms a limited-gap channel with the feed end of the conveyor belt 7. The V-shaped material-pushing ribs 611 enter the material stack layer to continuously push and shear the loose material, pre-dispersing any adhered or stacked rubber parts and pressing them to the feed position. Through the relative motion between the impeller 61 and the conveyor belt 7, the V-shaped material-supporting ribs 71 form a sling, and the inclined sides of the V-shape simultaneously generate lateral forces, causing the material to tend towards the belt centerline and reducing spillage from both sides. Through these actions, the V-shaped material-pushing ribs 611 of the impeller 61 achieve pre-dispersion, thickness limitation, and guiding at the feed inlet, suppressing bridging and overfeed / empty belt pulsation in the storage tank 3, improving the stability, thinning, and centering of the material entering subsequent workstations, thus working in conjunction with the V-shaped material-supporting ribs 71 of the conveyor belt 7 to achieve reliable upward feeding and consistent detection.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
