[0001] This utility model relates to the field of weighing and feeding machine technology, specifically a weighing and feeding machine with a lifting mechanism. Background Technology
[0002] Weighing feeders are production metering equipment used for the continuous conveying, dynamic metering, and controlled feeding of various powdery and bulk materials. They are widely used in industries such as cement, chemical, metallurgy, ceramics, grain, and transportation. As an automated metering and batching device, it can provide accurate metering data and control methods for on-site management and operation.
[0003] Existing weighing feeders with lifting mechanisms often experience leakage at their feed inlet connections over long periods of use. This can affect the normal operation of the device and consequently its working efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a weighing feeder with a lifting mechanism to solve the problem that the feed inlet connection of the existing weighing feeder with a lifting mechanism is prone to leakage under long-term use, which affects the normal use of the device and thus its working efficiency.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a weighing and feeding machine with a lifting mechanism, comprising a base, a load-bearing device, a placement box, and a collection box. The load-bearing device and the placement box are fixedly connected to the surface of the base. A cylinder is mounted on the surface of the base, and one end of the cylinder is slidably connected to the collection box. A clamping structure is provided on the surface of the base, including a connecting plate. The surface of the connecting plate is fixedly connected to the surface of the base. A groove is formed on the surface of the connecting plate, and a bidirectional screw is slidably connected to the inner wall of the groove. A clamping block is slidably connected to the inner wall of the groove, and the surface of the clamping block is threadedly connected to the arc surface of the bidirectional screw. A rotating plate is fixedly connected to one end of the bidirectional screw, and a bolt is slidably connected to the surface of the rotating plate. One end of the bolt is threadedly connected to the surface of the connecting plate. The connecting plate, fixed to the surface of the base, provides support and guidance for the movement of the bidirectional screw and the clamping block, and serves as the mounting foundation for the clamping structure. The bidirectional screw allows the two clamping blocks to move relative to or away from each other within the groove during rotation, achieving the clamping and releasing function. The clamping block is designed to directly contact the workpiece, gripping it via a bidirectional screw to prevent it from shaking or shifting during weighing and feeding. The rotating plate allows operators to easily rotate the bidirectional screw to change the clamping block's position. Bolts are used to fix the rotating plate in place, thus securing the clamping block and ensuring clamping stability.
[0007] Furthermore, a fixing block is fixedly connected to the surface of the clamping block, and a round rod is slidably connected to the surface of the fixing block. The fixing block and the round rod ensure that the fixing block is fixed to the surface of the clamping block, and the round rod is slidably connected to the fixing block, further enhancing the stability of the clamping block's movement.
[0008] Furthermore, a pad made of rubber is fixedly connected to the surface of the clamping block. The pad, being made of rubber, secures the clamping block to its surface, increases the friction between the clamping block and the object, and prevents the clamping block from damaging the object's surface.
[0009] Furthermore, a fixing rod is fixedly connected to the inner wall of the slide groove, and the arc surface of the fixing rod is slidably connected to the surface of the clamping block. The fixing rod is fixed to the inner wall of the slide groove, and the clamping block slides along its surface, thus guiding and stabilizing the movement of the clamping block.
[0010] Furthermore, the surface of the collection box is provided with a collection structure, which includes a groove. The surface of the collection box has a groove, and the inner wall of the groove has a square slot. A slider is slidably connected to the inner wall of the square slot, and a connecting rod is fixedly connected to the inner wall of the square slot. The arc surface of the connecting rod is slidably connected to the surface of the slider. A collection box is fixedly connected to the surface of the slider, and a handle is fixedly connected to the surface of the collection box. The collection box automatically slides back to its original position. The groove and square slot, located on the surface of the collection box, provide space and guidance for the movement of the slider and the collection box. The slider is fixedly connected to the collection box and slides along the connecting rod within the square slot, enabling the collection box to be pulled out. The connecting rod is fixed to the inner wall of the square slot, providing guidance for the slider's movement and ensuring the stability of the collection box's movement. The collection box is used to collect scattered or excess materials, facilitating cleaning and maintenance. The handle allows operators to easily pull the collection box to perform the pulling out and retraction operations.
[0011] Furthermore, the inner wall of the square groove is provided with ball bearings, which are made of steel. The ball bearings, located on the inner wall of the square groove and made of steel, reduce the friction between the slider and the inner wall of the square groove, making the collection box easier to pull out.
[0012] Furthermore, a spring is fitted onto the arcuate surface of the connecting rod. One end of the spring is fixedly connected to the surface of the slider, and the other end is fixedly connected to the inner wall of the square groove. This spring design allows it to fit over the arcuate surface of the connecting rod, with one end fixed to the slider surface and the other end fixed to the inner wall of the square groove. When the collection box is pulled out, the spring stretches; when the handle is released, the spring force causes the collection box to automatically return to its original position.
[0013] This utility model has the following beneficial effects:
[0014] This invention utilizes a clamping structure where rotating the rotating plate drives a bidirectional screw to rotate within a sliding groove. Because the clamping blocks are threadedly connected to the bidirectional screw, the rotation of the screw causes the two clamping blocks to slide relative to or away from each other within the groove, thus clamping or releasing the item. After adjusting the clamping block position, bolts are passed through the rotating plate and threadedly connected to the surface of the connecting plate to fix the rotating plate, thereby fixing the clamping block position. The connecting plate, fixed to the base surface, provides support and guidance for the movement of the bidirectional screw and clamping blocks, serving as the installation foundation for the clamping structure. The bidirectional screw allows the two clamping blocks to move relative to or away from each other within the sliding groove during rotation, achieving the clamping and releasing function. The clamping blocks directly contact the item, clamping it through the bidirectional screw and preventing it from shaking or shifting during weighing and feeding. The rotating plate allows operators to easily rotate the bidirectional screw to change the clamping block position. The bolts are used to fix the position of the rotating plate, thereby fixing the clamping blocks and ensuring clamping stability. The fixed block and round rod are designed to secure the fixed block to the surface of the clamping block, while the round rod slides between the fixed block and the fixed block, further enhancing the stability of the clamping block's movement. The pad, made of rubber, is fixed to the surface of the clamping block, increasing friction between the clamping block and the object while preventing damage to the object's surface. The fixed rod is fixed to the inner wall of the chute, allowing the clamping block to slide along its surface, guiding and stabilizing its movement. This clamping structure facilitates clamping at the feed inlet connection, minimizing leakage and further improving the device's operational stability.
[0015] This invention utilizes a collection structure where pulling the handle on the surface of the collection box causes it to slide along a connecting rod within a square groove via a slider, stretching a spring. When cleaning is required, the collection box can be fully pulled out. After cleaning, releasing the handle causes the collection box to automatically slide back to its original position under the spring's elasticity. The groove and square groove on the surface of the collection box provide space and guidance for the movement of the slider and the collection box. The slider is fixedly connected to the collection box and slides along the connecting rod within the square groove, enabling the collection box to be pulled out. The connecting rod is fixed to the inner wall of the square groove, guiding the slider's movement and ensuring the stability of the collection box's movement. The collection box is designed to collect scattered or excess materials, facilitating cleaning and maintenance. The handle allows operators to easily pull the collection box out and retract it. The ball bearing, located on the inner wall of the square groove and made of steel, reduces friction between the slider and the inner wall of the square groove, making the pulling out of the collection box smoother. The spring is designed to fit over the arc surface of the connecting rod, with one end fixed to the slider surface and the other end fixed to the inner wall of the square groove. When the collection box is pulled out, the spring stretches, and when the handle is released, the spring force causes the collection box to automatically return to its original position. This collection structure facilitates the collection of processed feed, minimizes feed spillage on the ground, and further improves the ease of operation of the device.

[0026] Please see Figure 1 - Figure 4 As shown, this utility model is a weighing and feeding machine with a lifting mechanism, including a base 1, a load-bearing device 2, a placement box 3, and a collection box 4. The load-bearing device 2 is fixedly connected to the surface of the base 1, the placement box 3 is fixedly connected to the surface of the base 1, a cylinder 7 is installed on the surface of the base 1, and the collection box 4 is slidably connected to one end of the cylinder 7. The surface of the base 1 is provided with a clamping structure 5, which includes a connecting plate 51. The surface of the connecting plate 51 is fixedly connected to the surface of the base 1. A groove 52 is opened on the surface of the connecting plate 51. A bidirectional screw 53 is slidably connected to the inner wall of the groove 52. A clamping block 56 is slidably connected to the inner wall of the groove 52. The surface of the clamping block 56 is threadedly connected to the arc surface of the bidirectional screw 53. A rotating plate 54 is fixedly connected to one end of the bidirectional screw 53. A bolt 55 is slidably connected to the surface of the rotating plate 54. One end of the bolt 55 is threadedly connected to the surface of the connecting plate 51. The connecting plate 51 is fixed to the surface of the base 1, providing support and guidance for the movement of the bidirectional screw 53 and the clamping blocks 56, and serving as the mounting foundation for the clamping structure 5. The bidirectional screw 53 allows the two clamping blocks 56 to move relative to or away from each other within the slide groove 52 during rotation, achieving the clamping and releasing function. The clamping blocks 56 are in direct contact with the items, clamping them through the bidirectional screw 53 and preventing them from shaking or shifting during weighing and feeding. The rotating plate 54 allows the operator to easily rotate the bidirectional screw 53 to change the position of the clamping blocks 56. The bolt 55 is used to fix the position of the rotating plate 54, thereby fixing the clamping blocks 56 and ensuring clamping stability.
[0027] A fixing block 57 is fixedly connected to the surface of the clamping block 56, and a round rod 58 is slidably connected to the surface of the fixing block 57. The fixing block 57 and the round rod 58 fix the fixing block 57 to the surface of the clamping block 56, and the round rod 58 is slidably connected to the fixing block 57, which further enhances the stability of the movement of the clamping block 56.
[0028] A pad 59, made of rubber, is fixedly connected to the surface of the clamp 56. The pad 59 is fixed to the surface of the clamp 56, and its rubber material increases the friction between the clamp 56 and the object, while preventing the clamp 56 from damaging the surface of the object.
[0029] A fixing rod 510 is fixedly connected to the inner wall of the slide groove 52, and the arc surface of the fixing rod 510 is slidably connected to the surface of the clamping block 56. The fixing rod 510 is fixed to the inner wall of the slide groove 52, and the clamping block 56 slides along its surface, which serves to guide and stabilize the movement of the clamping block 56.
[0030] The surface of the collection box 4 is provided with a collection structure 6, which includes a groove 63. The groove 63 has a square groove 64 on its inner wall. A slider 66 is slidably connected to the inner wall of the square groove 64, and a connecting rod 65 is fixedly connected to the inner wall of the square groove 64. The arc surface of the connecting rod 65 is slidably connected to the surface of the slider 66. A collection box 61 is fixedly connected to the surface of the slider 66, and a handle 62 is fixedly connected to the surface of the collection box 61. The collection box 61 automatically slides back to its original position. The groove 63 and the square groove 64, located on the surface of the collection box 4, provide space and guidance for the movement of the slider 66 and the collection box 61. The slider 66 is fixedly connected to the collection box 61 and slides along the connecting rod 65 within the square groove 64, enabling the collection box 61 to be pulled out. The connecting rod 65 is fixed to the inner wall of the square groove 64, guiding the sliding of the slider 66 and ensuring the stability of the movement of the collection box 61. The collection box 61 is designed to collect scattered or excess materials, facilitating cleaning and maintenance. The handle 62 allows operators to easily pull the collection box 61 to remove and retract it.
[0031] The inner wall of the square groove 64 is provided with ball bearings 68, which are made of steel. The ball bearings 68 are located on the inner wall of the square groove 64 and are made of steel. This reduces the friction between the slider 66 and the inner wall of the square groove 64, making the collection box 61 easier to pull out.
[0032] A spring 67 is fitted onto the arc surface of the connecting rod 65. One end of the spring 67 is fixedly connected to the surface of the slider 66, and the other end is fixedly connected to the inner wall of the square groove 64. The spring 67 is positioned to fit over the arc surface of the connecting rod 65, with one end fixed to the surface of the slider 66 and the other end fixed to the inner wall of the square groove 64. When the collection box 61 is pulled out, the spring 67 stretches; when the handle 62 is released, the elastic force of the spring 67 causes the collection box 61 to automatically return to its original position.
[0033] Rotating the rotating plate 54 causes the bidirectional screw 53 to rotate within the slide groove 52. Since the clamping blocks 56 are threadedly connected to the bidirectional screw 53, the rotation of the bidirectional screw 53 causes the two clamping blocks 56 to slide relative to or away from each other within the slide groove 52, thus clamping or releasing the item. After adjusting the position of the clamping blocks 56, the bolt 55 is passed through the rotating plate 54 and threadedly connected to the surface of the connecting plate 51 to fix the rotating plate 54, thereby fixing the position of the clamping blocks 56. The connecting plate 51 is fixed to the surface of the base 1, providing support and guidance for the movement of the bidirectional screw 53 and the clamping blocks 56, and serves as the installation foundation for the clamping structure 5. The bidirectional screw 53 allows the two clamping blocks 56 to move relative to or away from each other within the slide groove 52 during rotation, achieving the clamping and releasing function. The clamping blocks 56 directly contact the item, clamping it through the action of the bidirectional screw 53, preventing the item from shaking or shifting during weighing and feeding. The rotating plate 54 allows operators to easily rotate the bidirectional screw 53 to change the position of the clamping block 56. The bolt 55 is used to fix the position of the rotating plate 54, thereby securing the clamping block 56 and ensuring clamping stability. The fixing block 57 and the round rod 58 fix the fixing block 57 to the surface of the clamping block 56, while the round rod 58 slides between the fixing block 57 and the fixing block 57, further enhancing the stability of the clamping block 56's movement. The pad 59, made of rubber, is fixed to the surface of the clamping block 56, increasing the friction between the clamping block 56 and the object while preventing damage to the object's surface. The fixing rod 510 is fixed to the inner wall of the slide groove 52, allowing the clamping block 56 to slide along its surface, guiding and stabilizing the movement of the clamping block 56. The clamping structure 5 facilitates clamping at the feed inlet connection, minimizing leakage and further improving the device's operational stability.
[0034] Pulling the handle 62 on the surface of the collection box 61 causes the collection box 61 to slide along the connecting rod 65 within the square groove 64 via the slider 66, stretching the spring 67. When cleaning is required, the collection box 61 can be fully pulled out. After cleaning, releasing the handle 62 causes the collection box 61 to automatically slide back to its original position under the elastic force of the spring 67. The groove 63 and the square groove 64 are designed on the surface of the collection box 4, providing space and guidance for the movement of the slider 66 and the collection box 61. The slider 66 is fixedly connected to the collection box 61 and slides along the connecting rod 65 within the square groove 64, enabling the collection box 61 to be pulled out. The connecting rod 65 is fixed to the inner wall of the square groove 64, providing guidance for the sliding of the slider 66 and ensuring the stability of the movement of the collection box 61. The collection box 61 is designed to collect scattered or excess materials, facilitating cleaning and maintenance. The handle 62 allows operators to easily pull the collection box 61 to perform the pulling out and retraction operations. The ball bearing 68, located on the inner wall of the square groove 64 and made of steel, reduces friction between the slider 66 and the inner wall of the square groove 64, making the pulling of the collection box 61 smoother. The spring 67 is fitted onto the arc surface of the connecting rod 65, with one end fixed to the surface of the slider 66 and the other end fixed to the inner wall of the square groove 64. When the collection box 61 is pulled out, the spring 67 stretches; when the handle 62 is released, the elastic force of the spring 67 automatically resets the collection box 61. This collection structure 6 facilitates the collection of processed feed, minimizing spillage and further improving the ease of operation of the device.
