Description

Technical Field

[0001] This invention belongs to the field of rubber molding, and specifically relates to a molding apparatus for processing butyl rubber bottle stoppers. Background Technology

[0002] With the development of industrial technology, modern rubber molding technology has become more and more perfect. Butyl rubber bottle stoppers have high elasticity, and therefore, when butyl rubber bottle stoppers are attached to the side wall of glass bottles, they have good airtightness. During the processing of butyl rubber bottle stoppers, a whole strip of rubber needs to be cut into sections. The previous cutting method was relatively inefficient.

[0003] The crown thickness control device for vulcanized butyl rubber pharmaceutical bottle stoppers disclosed in patent CN112476876A includes a bottle stopper mold, a limiting rod fixedly welded to the side of the bottle stopper mold, a circular movable plate tightly fitted to the limiting rod, a connecting rod with one end installed on the top of the movable plate, the other end of the connecting rod installed at the bottom of a movable crossbar, the two ends of the movable crossbar movably engaged in a rectangular slide rail, a stabilizing block with a circular through hole installed on the top of the rectangular slide rail, a small gear ring movably engaged with a large gear, a connecting block fixedly installed at the bottom of the large gear, a support rod with one end movably installed on the side of the connecting block and the other end of the support rod installed on the slide rail, the bottle stopper mold is placed in a clamping device for fixation, the crown clamp and bottom clamp in the clamping device fix the crown and bottom positions of the bottle stopper mold, a rubber gasket is set at the bottom to prevent damage to the bottle stopper mold, stabilize the position of the bottle stopper mold, and make operation more convenient;

[0004] The device has several shortcomings. First, its positioning for processing rubber raw materials is not precise enough, which can easily lead to non-standard product shapes. Second, previous rubber material processing devices were not equipped with testing facilities, requiring the processed rubber products to be sent to specialized testing equipment for further processing, which is a waste of human resources. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a molding apparatus for processing butyl rubber bottle stoppers. In use, the strip of butyl rubber to be processed is inserted through the rear end of an insertion tube. The operator then installs a surrounding push rod onto the side wall of an extension plate. A stepper motor drives a gear disk to rotate via a reduction gear, and a threaded rod rotates synchronously with the gear. During rotation, the threaded rod drives a nut block and a slider to slide back and forth along a guide rail. The extension plate and the surrounding push rod on its side wall also slide along with the slider, gradually advancing the strip of butyl rubber. The strip of butyl rubber stops after advancing one unit distance, and a cutting hydraulic press extends a blade that inserts into a cutting groove to cut the strip of butyl rubber into bottle stoppers, thereby solving the problems mentioned in the background art.

[0006] To solve the above problems, the present invention provides the following technical solution: a molding device for processing butyl rubber bottle stoppers, comprising a fixed platform and an insertion platform, wherein the insertion platform is fixedly disposed below the fixed platform, and a rubber material feeding channel is provided inside the insertion platform, into which the cylindrical rubber material to be processed is inserted; a threaded rod is fixedly installed on the front side wall of the fixed platform, and a slider is slidably disposed on the threaded rod; a push rod mechanism matching the rubber material feeding channel is provided on the side wall of the slider, and the slider is connected to a linear propulsion mechanism, the linear propulsion mechanism including a bearing on the front side wall of the fixed platform, the outer ring of the bearing being fixedly connected to the side wall of the fixed platform, and a threaded rod being fixedly disposed in the inner ring of the bearing, wherein the threaded rod is sleeved on the threaded rod. The system includes a nut block with a connecting frame on its side wall, which is connected to the side wall of a slider. The threaded rod is connected to a torsion mechanism. A movable platform is movably mounted on one side of the fixed platform, and an ink-dispensing mechanism matching the cylindrical rubber material is mounted on the side wall of the movable platform. The top of the insertion platform has an insertion tube inserted inside. The rear end of the insertion tube has an ink-dispensing horizontal groove, and the front end of the insertion tube has a cutting vertical groove. The ink-dispensing horizontal groove and the cutting vertical groove are perpendicular to each other, and the overlap length between the ink-dispensing horizontal groove and the cutting vertical groove is one-sixth of the length of the insertion tube. A cutting hydraulic press is fixedly mounted at the bottom of the insertion platform. A blade is mounted on the telescopic rod of the cutting hydraulic press, and a blade groove matching the blade is mounted on the side wall of the insertion tube.

[0007] In use, the strip of butyl rubber to be processed is inserted into the rear end of the insertion tube. As the threaded rod rotates, it drives the nut block and the slider to slide back and forth along the guide rail. The push rod mechanism also slides with the slider and pushes the strip of butyl rubber forward step by step. The strip of butyl rubber stops after advancing one unit distance inside the insertion tube. The cutting hydraulic press drives the blade to extend and insert into the cutting groove to cut the strip of butyl rubber into pieces of bottle stopper, thus achieving efficient cutting.

[0008] Furthermore, the push rod mechanism includes an extension plate, the upper end of which is connected to the side wall of the slider, and the lower end of the slider is detachably provided with a surrounding push rod, which can be inserted into the rear end of the insertion tube.

[0009] When in use, the operator installs the surrounding top rod onto the side wall of the extension plate. The extension plate and the surrounding top rod on its side wall will slide together with the slider and push the strip butyl rubber forward step by step.

[0010] Furthermore, the diameter of the surrounding top rod is smaller than the width of the ink-dotting horizontal groove.

[0011] During use, the surrounding top rod can be inserted into the ink dot groove during assembly, which increases the speed of assembly.

[0012] Furthermore, a block is provided at the lower end of the extension plate, and a square hole matching the block is provided at the end of the surrounding top rod. The block is made of iron, and a magnet is provided inside the square hole at the end of the surrounding top rod.

[0013] When using it, during the installation process, align the square hole at the end of the ring rod with the block and insert it until the block and the square hole are attracted to each other.

[0014] Furthermore, the torsion mechanism includes a stepper motor on the side wall of the fixed platform, a reduction gear is mounted on the rotating shaft of the stepper motor, and a gear disk is also provided on the outer side wall of the threaded rod, the gear disk and the reduction gear meshing with each other.

[0015] In use, the stepper motor drives the gear disk to rotate through the reduction gear, and the threaded rod rotates synchronously with the gear. During the rotation, the threaded rod drives the nut block and the slider to slide back and forth along the guide rail.

[0016] Furthermore, the ink dispensing mechanism includes a movable platform, an ink cartridge is provided on the front side wall of the movable platform, an ink dispensing tube is connected to the side wall of the ink cartridge, the end of the ink dispensing tube is aligned with the slot of the ink dispensing groove in the horizontal direction, an ink pump is provided inside the ink cartridge, and the movable platform is connected to a linkage mechanism.

[0017] During use, the ink cartridge and ink dispensing tube on the side wall of the active platform are inserted into the ink dispensing groove to mark a segment on the side wall of the strip butyl rubber. Each rubber plunger cut into pieces will have a segment marked. The staff can refer to the segment marked to determine whether the length of each rubber plunger meets the standard. The segment marked can also serve as a reference standard for subsequent processing steps.

[0018] Furthermore, the linkage mechanism includes two crossbars fixedly mounted on the side wall of the movable platform. The side wall of the fixed platform is provided with sliding holes that match the crossbars. The two crossbars are respectively inserted into the sliding holes on the side wall of the fixed platform. A return spring is fitted on the outer side of the crossbar. One end of the return spring is fixedly connected to the side wall of the movable platform, and the other end of the return spring is fixedly connected to the side wall of the fixed platform. A cam is provided at the rear end of the threaded rod. A cantilever rod is provided on the rear side wall of the movable platform. An arc-shaped tile is provided at the outer end of the cantilever rod, and the arc-shaped tile abuts against the side wall of the cam.

[0019] During use, each time the threaded rod rotates once, the cam at the end of the threaded rod will push the arc-shaped tile forward once, and the movable table will move away from the fixed table once. Thus, the movement of the ink tube and the threaded rod are linked, which increases the accuracy of the marking line drawn by the ink tube.

[0020] Furthermore, the width of the blade and the groove is greater than the inner diameter of the insertion tube, and the width of the blade and the groove is less than the outer diameter of the insertion tube.

[0021] When in use, the blade goes deep into the cutting groove and completely penetrates it to achieve the cut. The telescopic rod of the cutting hydraulic press can be inserted into the cutting vertical groove.

[0022] Compared with the prior art, the embodiments of this application have the following main advantages:

[0023] Firstly, when using the device, the strip of butyl rubber to be processed is inserted into the rear end of the insertion tube. Then, the operator installs the surrounding top rod onto the side wall of the extension plate. The stepper motor drives the gear disk to rotate through the reduction gear, and the threaded rod rotates synchronously with the gear. During the rotation of the threaded rod, it drives the nut block and the slider to slide back and forth along the guide rail. The extension plate and the surrounding top rod on its side wall also slide along with the slider, pushing the strip of butyl rubber forward step by step. The strip of butyl rubber stops after each unit distance is pushed forward, and the cutting hydraulic press drives the blade to extend and insert into the cutting groove to cut the strip of butyl rubber into pieces of bottle stopper.

[0024] Secondly, with each rotation of the threaded rod, the cam at the end of the threaded rod will push the arc-shaped tile forward once, causing the movable table to move away from the fixed table once. The ink cartridge and ink tube on the side wall of the movable table will insert from the ink dispensing groove and mark a segment on the side wall of the strip butyl rubber. Each piece of rubber plunger will have a segment marked on it. Workers can refer to the segment marked to determine whether the length of each rubber plunger meets the standard. The segment marked can also serve as a reference standard for subsequent processing steps. Attached Figure Description
