Description

Technical Field

[0001] This utility model relates to the technical field of combination scales, and in particular to a multi-head combination scale suitable for weighing long strip materials in combination. Background Technology

[0002] Existing combination scales generally include a main vibrating plate mounted on a frame, multiple linear vibrating plates circumferentially distributed around the main vibrating plate, a storage hopper located below the discharge end of each linear vibrating plate, a weighing hopper located below each storage hopper, and a discharge hopper that receives the material output from the multiple weighing hoppers. When the total weight of the material in several of the multiple weighing hoppers equals a set weight, the material is discharged from these hoppers, allowing it to collect in the discharge hopper and be discharged from the outlet below the discharge hopper. The bodies of the storage hopper and the weighing hopper of this type of combination scale are generally square structures. When long strips of material enter, it is not conducive to material aggregation and is not suitable for use with long strips of material. In addition, this type of combination scale only has a limited probability of multiple weighing hoppers forming a weight combination, resulting in a limited combination probability, low combination efficiency, and is not conducive to accurate weighing. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a multi-head combination scale suitable for weighing long strip materials to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a multi-head combination scale suitable for weighing long strip materials is designed, comprising: a main vibrating plate mounted on a frame; multiple linear vibrating plates circumferentially distributed around the main vibrating plate; a storage hopper located below the discharge end of each linear vibrating plate; a weighing hopper located below the discharge end of each storage hopper; a memory hopper located below the discharge end of each weighing hopper; a guide component located below the discharge end of each memory hopper and having an internal guide chute; a discharge hopper for receiving materials output from multiple guide components; and a control device, wherein the storage hopper body and the weighing hopper... Both the hopper body and the memory hopper body are cylindrical structures with an opening at the top larger than at the bottom. Each weighing hopper is connected to a weighing sensor. The weighing sensor, the first drive device for controlling the material discharge from the storage hopper, the second drive device for controlling the material discharge from the weighing hopper, and the third drive device for controlling the material discharge from the memory hopper are electrically connected to the control device. The control device is used to control several memory hoppers to discharge material simultaneously or to control several memory hoppers and one or more weighing hoppers above them to discharge material simultaneously according to the set weighing command.

[0006] By adopting the above technical solution, the bodies of the storage hopper, weighing hopper, and memory hopper are all designed as cylindrical structures with an upper opening larger than a lower opening. When long strips of material enter, they are easily gathered within the hopper body, making it suitable for receiving and conveying long strips of material. A memory hopper is installed below the discharge end of each weighing hopper. After the weighing hopper discharges the weighed material into the memory hopper, the control device records the weight of the material entering each memory hopper. The control device controls several memory hoppers to discharge material simultaneously or controls several memory hoppers and one or more weighing hoppers above them to discharge material simultaneously, thereby improving the probability and efficiency of material combination and facilitating accurate weighing.

[0007] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0008] In some embodiments, the linear vibratory feeder has a long, narrow structure, with its internal guide trough forming an isosceles trapezoid that is wider at the top and narrower at the bottom. This facilitates the conveying of long, narrow materials.

[0009] In some embodiments, the weighing hopper includes a hopper body, two hopper frame plates fixedly connected to the hopper body, two gate components hinged to the left end of the hopper frame plates and two movable plates hinged to the right end, a linkage plate with one end hinged to one of the gate components and the other end hinged to one of the movable plates, a first rod fixedly connected to the two movable plates, a second rod and a third rod fixedly connected to the two hopper frame plates, and a hanging frame. The teeth at the upper ends of the two gate components are engaged, and the lower gate plates are located below the hopper body. The second rod is hung in a hanging groove on the upper part of the hanging frame. The third rod is fitted into the limiting groove at the lower end of the hanger. The hanger is fixedly connected to the weighing end of the weighing sensor. The second driving device includes a driving unit, a connecting plate fixedly connected to the driving end of the driving unit, and a rotating wheel that is rotatably engaged with the connecting shaft fixedly connected to the other end of the connecting plate. The rotating wheel is located below the first rod. When the driving device drives the connecting plate to rotate, it causes the rotating wheel to rotate circumferentially. The rotating wheel rotates circumferentially and abuts against the first rod, driving the first rod to swing upward. It also drives two gate components to open and discharge material through the linkage plate.

[0010] In some embodiments, the weighing hopper further includes a tension spring, the upper end of which is connected to a connecting post on the movable plate, and the lower end of which is connected to a connecting post on the bucket frame plate. The right end of the bucket frame plate is bent to form a limiting plate located on the right side of the movable plate.

[0011] In some implementations, the drive unit is a stepper motor or a servo motor. Attached Figure Description

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, and fixing should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] refer to Figures 1 to 5As shown, the present invention provides a multi-head combination scale suitable for weighing long strip materials, comprising: a main vibrating plate 1 mounted on a frame, multiple linear vibrating plates 2 circumferentially distributed around the main vibrating plate 1, a storage hopper 3 located below the discharge end of each linear vibrating plate 2, a weighing hopper 4 located below the discharge end of each storage hopper 3, a memory hopper 5 located below the discharge end of each weighing hopper 4, a guide component 6 located below the discharge end of each memory hopper 5 and having a guide chute inside, a discharge hopper 7 for receiving materials output from multiple guide components 6, and a control device.

[0023] The linear vibratory plate 2 has a long strip structure, and the internal guide groove is an isosceles trapezoidal structure that is wider at the top and narrower at the bottom. The linear vibratory plate 2, the guide component 6, and the discharge hopper 7 are fixedly connected to the frame.

[0024] The hopper body of storage hopper 3, the hopper body of weighing hopper 4, and the hopper body of memory hopper 5 are all cylindrical structures with an opening at the top that is larger than the opening at the bottom.

[0025] Each weighing hopper 4 is connected to a weighing sensor 8.

[0026] The weighing hopper 4 includes a hopper body 41, two hopper frame plates 42 fixedly connected to the hopper body 41, two gate components 43 hinged to the left end of the hopper frame plates 42, two movable plates 44 hinged to the right end of the hopper frame plates 42, a linkage plate 45 with one end hinged to one of the gate components 43 and the other end hinged to one of the movable plates 44, a first rod 46 fixedly connected to the two movable plates 44, a second rod 47 and a third rod 48 fixedly connected to the two hopper frame plates 42, a hanger 49, and a tension spring 401. The teeth at the upper ends of the two gate components 43 are engaged, and the gate plates 431 at the lower ends of the two gate components 43 are both located below the hopper body 41. Two gates 431 are used to block the material from falling into the bucket 41. The second rod 47 is hooked into the hanging groove 491 on the upper part of the bracket 49, and the third rod 48 is fitted into the limiting groove 492 at the lower end of the bracket 49. The bracket 49 is fixedly connected to the weighing end of the weighing sensor 8. The weight of the material falling into the weighing bucket 4 can be weighed through the weighing sensor 8. The upper end of the tension spring 401 is connected to the connecting post on the movable plate 44, and the lower end is connected to the connecting post on the bucket frame plate 42. The right end of the bucket frame plate 42 is bent to form a limiting plate 421 located on the right side of the movable plate 44. The limiting plate 421 is used to control the material falling into the bucket 41. The movable plate 44 is used for limiting. The weighing sensor 8 and the second drive device 9 are directly fixed to the frame or both are installed in an aluminum box fixed to the frame. The second drive device 9 includes a drive unit 91, a connecting plate 92 fixed to the drive end of the drive unit 91, and a rotating wheel 93 that is rotatably engaged with the connecting shaft fixed to the other end of the connecting plate 92. The rotating wheel 93 is located below the first rod 46. The drive unit 91 is a stepper motor or a servo motor. When the drive unit 91 drives the connecting plate 92 to rotate, it causes the rotating wheel 93 to rotate circumferentially. The rotating wheel 93 abuts against the first rod 46 and drives the first rod. The first rod body 46 swings upward, pulling the right end of the linkage plate 45 upward, causing the right gate component 43 to rotate counterclockwise around its upper hinge axis, and the left gate component 43 to rotate clockwise around its upper hinge axis, thereby opening the lower ends of the two gate components 43 to allow material to be discharged. When the drive unit 91 drives the connecting plate 92 to rotate, it causes the rotating wheel 93 to rotate circumferentially, so that the rotating wheel 93 does not contact the first rod body 46. Under the action of the tension spring 401, the movable plate 44 is driven to reset and contact the limit plate 421, and the two gate components 43 are also reset to block the material discharge.

[0027] The storage hopper 3 and memory hopper 5 have the same structure as the weighing hopper 4, and the first drive device and the third drive device have the same structure as the second drive device 9. Alternatively, the storage hopper 3 and memory hopper 5 have the same feeding principle as the weighing hopper 4, but the shapes of the components are slightly different.

[0028] The weighing sensor 8, the first drive device for controlling the material discharge of the storage hopper 3, the second drive device 9 for controlling the material discharge of the weighing hopper 4, and the third drive device for controlling the material discharge of the memory hopper 5 are electrically connected to the control device. The control device is a conventional industrial control all-in-one computer, microcontroller, or PLC controller, etc. The control device can control the first drive device, the second drive device 9, and the third drive device to start and stop, thereby controlling the material discharge of the storage hopper 3, the weighing hopper 4, and the memory hopper 5 to either discharge or shut down the material discharge.

[0029] When long strips of material need to be weighed, they are placed on the main vibrating plate 1. The control device controls the main vibrating plate 1 to vibrate, dispersing the long strips of material into multiple linear vibrating plates 2. The multiple linear vibrating plates 2 vibrate to convey the long strips of material into multiple storage hoppers 3. After the main vibrating plate 1 and linear vibrating plates 2 start for a set time, they stop. The control device controls the first drive device to drive the storage hopper 3 to discharge the long strips of material into the weighing hopper 4. After that, the storage hopper 3 closes its discharge mechanism. Each weighing sensor 8 feeds back the weighed weight information to the control device. Then, the control device controls the second drive device to drive the weighing hopper 4 to discharge the long strips of material into the memory hopper 5. After that, the weighing hopper 4 closes its discharge mechanism. The control device records the weight of the material entering each memory hopper 5. When the storage hopper 3 discharges material into the weighing hopper 4 again... Each weighing sensor 8 feeds back the weighing information to the control device. When the combined scale needs to output a set weight of material, when the control device analyzes that the sum of the weights of the materials in several memory hoppers 5 equals the set weight of the material, or analyzes that the sum of the weights of the materials in several memory hoppers 5 and the weights of the materials in one or more weighing hoppers above the memory hoppers 5 equals the set weight of the material, the control device controls several memory hoppers 5 to discharge material simultaneously or controls several memory hoppers 5 and one or more weighing hoppers above the memory hoppers 5 to discharge material simultaneously according to the set weighing command. After that, the material passes through the guide chute on the guide component 6 into the discharge hopper 7 and is output from the discharge port below the discharge hopper 7.

[0030] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
