Description

Technical Field

[0001] This application relates to the field of testing equipment technology, specifically to a fully automatic weighing device. Background Technology

[0002] Glass wool board is a deep-processed product of glass wool. It is made by melting glass, fiberizing it, adding adhesives and solidifying it into glass wool rolls, and then processing it through polishing, adhesive spraying, papering and other processes.

[0003] During product manufacturing, various factors can affect the quality of glass wool boards, making it impossible to guarantee 100% compliance. To avoid impacting sales, most factories first use machinery to inspect the produced products and then use labeling machines to label the qualified ones. Some of these machines weigh the products. While existing weighing equipment can detect the weight of the products, the labeled glass wool boards cannot be automatically stacked and mostly require manual handling. Therefore, these issues urgently need to be addressed. Summary of the Invention

[0018] The support plate is provided with corresponding threaded sleeves at the four corners of the lead screw;

[0019] The threaded sleeve is fitted onto the lead screw and is threadedly connected to the lead screw.

[0020] Furthermore,

[0021] The lead screw is driven by a stepper motor and its end extends into the interior of the base.

[0022] The stepper motor is fixedly installed on one side of the base, and a first worm gear extending into the base is installed at the output end;

[0023] The first worm extends in a direction perpendicular to the first direction and is connected to the lead screw via connecting rods.

[0024] Furthermore,

[0025] The number of the connecting rods includes two, and their extension directions are parallel to the first direction, respectively;

[0026] The ends of the two connecting rods are respectively driven to the lead screw via bevel gear sets, and the middle part is respectively driven to the first worm via a first worm wheel.

[0027] Furthermore,

[0028] The support plate is also provided with countersunk holes arranged in an array;

[0029] A matching support component is movably installed inside the countersunk hole;

[0030] The support member is I-shaped and is used to support the glass wool board, forming an insertion gap.

[0033] The sliding direction of the linear guide is parallel to the first direction, and it is connected to the lever via a mounting base.

[0034] Furthermore,

[0035] The mounting base is driven by a servo motor and is connected to the servo motor via a ball screw drive.

[0036] The servo motor is fixedly mounted on the negative pressure box, and its output end is driven by the two ball screws respectively through the second worm gear.

[0037] The two ball screws are respectively driven by the second worm gear through a matching second worm wheel.

[0038] Furthermore,

[0040] The cylinder body of the dual-headed cylinder is fixedly mounted on the mounting base and connected to the paddle via a piston rod, which is used to drive the paddle to move up and down relative to each other.

[0041] The advantages and positive effects of this application are:

[0042] This technical solution involves setting up a weighing conveyor belt between the feeding and unloading conveyor belts, allowing the produced glass wool boards to be weighed and inspected directly during the conveying process. Simultaneously, the unloading conveyor belt connects to the unloading mechanism. When the glass wool board is transported to the designated position, a negative pressure box generates an upward suction force, thus counteracting most of its own weight. With the assistance of a paddle shifter, it is then conveyed onto a support plate. The support plate can be raised and lowered on the base, effectively ensuring that the top surface of the stacked glass wool boards is always flush with the conveying surface of the unloading conveyor belt.

Detailed Implementation

[0048] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0049] Please refer to Figure 1-4 This embodiment provides a fully automatic weighing device, including a frame 100 extending along a first direction, with a weighing conveyor belt 110 in the middle and a loading conveyor belt 120 and a unloading conveyor belt 130 at both ends; an unloading mechanism located at one end of the frame 100 near the unloading conveyor belt 130, including a lifting platform and a negative pressure box 200 arranged vertically; the lifting platform is located below the negative pressure box 200 and includes a base 210 and a support plate 220 that can be lifted and lowered on the base 210; one end of the negative pressure box 200 extends above the unloading conveyor belt 130, and the bottom is provided with an array of negative pressure holes 201 and a lever 230 for driving glass wool boards; the lever 230 is slidably mounted on the negative pressure box 200, and the sliding direction is parallel to the first direction.

[0050] In this embodiment, the frame 100 extends along the first direction, and the extension direction is parallel to the production output direction of the glass panel, so that the feeding conveyor belt can directly receive and transport the output glass wool board; a weighing conveyor belt and a printing and labeling device are respectively provided in the middle of the frame 100, which can directly weigh the glass wool board during the transportation process and affix the corresponding information label.

[0051] In this embodiment, the unloading mechanism is installed at the end of the unloading conveyor belt 130 away from the weighing conveyor belt 110, and is used to stack and collect the tested glass wool boards. The unloading mechanism includes a lifting platform and a negative pressure box 200 arranged vertically. The lifting platform is located below the negative pressure box 200 and is used to support and store the glass wool boards. The negative pressure box 200 is located above the lifting platform and extends above the unloading conveyor belt 130. When the glass wool boards are conveyed to the end of the unloading conveyor belt 130, their own weight can be counteracted by the upward suction force. Therefore, when entering the unloading mechanism, there will not be too much friction with the support plate 220 or the glass wool boards below, effectively ensuring that the labels and board surfaces will not be damaged due to friction.

[0053] In this embodiment, vertical support columns 240 are provided at the four corners of the base 210, and each support column 240 is also provided with a parallel lead screw 241; the two ends of the lead screw 241 are rotatably connected to the support column 240 through bearings.

[0054] In a preferred embodiment, the lead screw 241 is located on the side of the two support columns 240 arranged along the first direction that are close to each other; the four corners of the support plate 220 are respectively provided with corresponding threaded sleeves 221 corresponding to the lead screw 241; the threaded sleeves 221 are sleeved on the lead screw 241 and are threadedly connected to the lead screw 241.

[0055] In this embodiment, the lead screw 241 is located on one side of the two support columns 240 arranged along the first direction that are close to each other; at the same time, the lead screw 241 is also fitted with a matching threaded sleeve 221; the threaded sleeve 221 is threadedly connected to the lead screw 241 and fixedly connected to the support plate 220, so that the support plate 220 can be driven to rise and fall by rotating the lead screw 241.

[0057] In this embodiment, the base 210 includes a bottom plate parallel to the support plate 220 and a crossbeam located on the side of the bottom plate away from the support plate 220; the end of the lead screw 241 away from the negative pressure box 200 passes through the cavity located below the bottom plate.

[0058] In this embodiment, the stepper motor 250 is fixedly mounted on the crossbeam, and the output end is equipped with a first worm gear 251 through a reducer; the extension direction of the first worm gear 251 is perpendicular to the first direction, and the four lead screws 241 can be synchronously driven through the matching connecting rod 260.

[0059] In a preferred embodiment, the number of connecting rods 260 includes two, with their extension directions being parallel to the first direction; the ends of the two connecting rods 260 are respectively driven to the lead screw 241 via bevel gear sets, and the middle part is respectively driven to the first worm 251 via a first worm wheel 261.

[0060] In this embodiment, there are two connecting rods 260, which are parallel to each other. They are driven and connected in the middle by a first worm gear 261, and at both ends by a bevel gear set and a corresponding lead screw 241, thereby realizing that the first worm gear 261 synchronously drives the four lead screws 241 to rotate.

[0066] In this embodiment, the paddle 230 is connected to the mounting base 232 via a double-headed cylinder 237. When the glass wool board is being conveyed by the feeding conveyor belt 130, the paddle 230 will be kept in a retracted state by the double-headed cylinder 237, so as not to affect the conveying of the glass wool board. When the glass wool board is conveyed to the designated position, the paddle 230 will be extended by the double-headed drive 237 so that it abuts against the tail of the glass wool board. At this time, the glass wool board is also below the negative pressure box 200.

[0067] In this embodiment, a part of the negative pressure box 200 is provided with a negative pressure hole, which can generate an upward suction force on the glass wool board located below, thereby counteracting its gravity; at this time, the glass wool board is transported by the lever 230.
