Description

Technical Field

[0001] This utility model relates to the field of rubber sheet production and manufacturing, specifically to a rubber sheet weighing, sorting and conveying mechanism. Background Technology

[0002] The preparation of rubber sheets typically involves a process of raw material preparation, plasticizing, mixing, molding, vulcanization, cutting, inspection, and packaging. In some industrial applications requiring frequent friction, such as conveyor belts and seals, rubber sheets with insufficient basis weight will show wear marks more quickly, affecting the normal operation of the equipment. Insufficient basis weight may lead to uneven or too low crosslinking density, making the elastic properties of the rubber sheet unstable. This may result in insufficient elasticity, failing to quickly return to its original shape after being subjected to force, or excessively weak elasticity, failing to provide sufficient support and cushioning. Therefore, it is necessary to sort out rubber sheets with insufficient basis weight during the inspection stage to ensure product quality.

[0003] Chinese utility model patent CN221416738U discloses an automatic weighing rubber strip cutting machine. It weighs the rubber strips using a weighing module. If the rubber strip is underweight, the control system and motor control a rotating support frame to tilt it, causing it to fall into a receiving tray. When the rubber strip is heavy enough, the control system extends an electric push rod, causing the rubber strip to fall onto the discharge conveyor belt. However, its drawback is:

[0004] Before the material rack or electric push rod is reset, the weighing module cannot weigh the subsequent rubber strips, resulting in a longer time required for a single sorting and low sorting efficiency. Summary of the Invention

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0046] The rubber sheet weighing, sorting, and conveying mechanism provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0047] Example 1:

[0048] like Figures 1 to 4 As shown, this application embodiment provides a rubber sheet weighing, sorting and conveying mechanism, including a frame 1, a feeding conveyor belt 2, a discharging conveyor belt 3 and a weighing module 4, and also includes a flipping conveyor mechanism 5, which is disposed between the discharging conveyor belt 3 and the discharging conveyor belt 3, with one end movably connected to the discharging conveyor belt 3, and can flip up and down around the connection.

[0049] Furthermore, it also includes a cylinder 6, the bottom of which is hinged to the frame 1, and the outer end of the piston rod is hinged to the free end of the flipping conveyor mechanism 5.

[0050] Furthermore, the flipping conveyor 5 includes a pair of frames 51, both of which are hinged to one end of the discharge conveyor belt 3 via hinge shafts 512; and a number of conveyor rollers 52, which are rotatably installed between the pair of frames 51.

[0051] In this embodiment of the application, due to the above-described structure, the weighing module 4 is installed in the feeding conveyor belt 2 via a bracket, which can weigh the rubber sheet passing through the feeding conveyor belt 2. Then, the control system determines whether the cylinder 6 needs to be operated based on whether the rubber sheet is sufficiently heavy. When the rubber sheet on the feeding conveyor belt 2 is sufficiently heavy, the cylinder 6 does not operate, and the sufficiently heavy rubber sheet is transferred from the feeding conveyor belt 2 to each conveyor roller 52, and then enters the discharge conveyor belt 3, and is discharged from the other end of the discharge conveyor belt 3 to enter the next process. When the rubber sheet is insufficiently heavy, the cylinder 6 operates, controlling the free end of the frame 51 to lift, so that the insufficiently heavy rubber sheet falls directly from the end of the feeding conveyor belt 2 near the discharge conveyor belt 3 into the frame 1 (a container can be preset in the frame 1 to receive these insufficiently heavy rubber sheets). Then, the cylinder 6 resets, causing the free end of the frame 51 to descend, connecting the feeding conveyor belt 2 and the discharge conveyor belt 3.

[0052] Example 2:

[0053] like Figures 2 to 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the frame 51 includes a lower body 511, one end of which is rotatably connected to a hinge shaft 512, and a plurality of lower semicircular grooves 513 are provided on the inner side of the bottom; an upper body 514, one end of which is rotatably connected to a hinge shaft 512, and a plurality of upper semicircular grooves 515 are provided on the inner side of the top; and a plurality of locking mechanisms 7 for fixing the lower body 511 and the upper body 514 to each other, and each upper semicircular groove 515 and the corresponding lower semicircular groove 513 can be closed.

[0054] Furthermore, the locking mechanism 7 includes a mounting groove 71 disposed on the top surface of the lower body 511; a pair of sliders 72 slidably mounted in the mounting groove 71, forming a locking groove 73 between adjacent sides; a locking block 74 fixed on the top surface of the upper body 514 for locking with the locking groove 73; and an unlocking mechanism 75 for controlling the separation / closing of the pair of sliders 72.

[0055] Furthermore, the locking mechanism 7 also includes a number of semi-circular protrusions 76, symmetrically spaced on the opposite side wall of the locking groove 73; and a number of semi-circular grooves 77, symmetrically spaced on the opposite side wall of the locking block 74, for engaging with each semi-circular protrusion 76.

[0056] Preferably, both the locking block 74 and the locking groove 73 are arc-shaped and concentric with the hinge shaft 512.

[0057] Furthermore, the locking mechanism 7 also includes a slide bar 78, which slides through a pair of sliders 72, with its two ends fixed to the left and right walls of the mounting groove 71, respectively.

[0058] Furthermore, several rollers are rolled on the inner circumferential walls of each upper and lower circular groove, and the axis of each roller is parallel to the axis of the conveyor roller 52.

[0059] In this embodiment of the application, due to the above-described structure, when the conveyor roller 52 needs to be disassembled, the unlocking mechanism 75 is operated to separate the pair of sliders 72, the locking groove 73 is opened, and each semi-circular protrusion 76 separates from each semi-circular groove 77, releasing the locking state of the locking block 74. Then, the free end of the upper body 514 is flipped upward to expose the upper surface of the lower body 511, so that the conveyor roller 52 can be removed from each lower semi-circular groove 513. When installing the conveyor roller 52, first remove each conveyor roller... The two ends of 52 are placed in the corresponding pairs of lower semicircular grooves 513. Then, the upper body 514 is flipped downward around the hinge shaft 512 until it closes with the lower body 511. Each lower semicircular groove 513 and the corresponding upper semicircular groove 515 close to form a sealed circle. The peripheral wall of the end of the conveyor roller 52 contacts the peripheral wall of each roller. The unlocking mechanism 75 is operated to close a pair of sliders 72, the locking groove 73 shrinks, and each semicircular protrusion 76 and each semicircular groove 77 engage with each other, thus completing the installation of the conveyor roller 52.

[0060] Example 3:

[0062] Furthermore, the unlocking mechanism 75 also includes a pair of pressure springs 754, which are respectively disposed on the outer side of each unlocking block 752 and between the adjacent side wall of the mounting groove 71.

[0063] In this embodiment of the application, due to the above-described structure, when it is necessary to separate the pair of sliders 72, the unlocking block 752 is pressed into the mounting groove 71, causing the unlocking block 752 to extend into the mounting groove 71. The upper ends of the pair of connecting arms 753 push the pair of sliders 72 to separate, and each pressure spring 754 is compressed. When it is necessary to close the pair of sliders 72, the unlocking block 752 is released, and each pressure spring 754 releases its elastic potential energy, pushing the pair of sliders 72 to close. The upper ends of the pair of connecting arms 753 move closer to each other, and the lower ends push the unlocking block 752 downward out of the mounting groove 71.
