Description

Technical Field

[0001] The present invention belongs to the field of rubber molding, and particularly relates to a molding device for processing butyl rubber stoppers. Background Art

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

[0003] A crown thickness control device for vulcanizing and molding butyl rubber medical stoppers disclosed in Patent CN112476876A includes a stopper mold. A limiting rod is fixedly welded to the side of the stopper mold. A circular movable plate closely fits the limiting rod. One end of a connecting short rod is installed on the top of the movable plate, and the other end of the connecting short rod is installed at the bottom of a movable cross bar. Both ends of the movable cross bar are movably clamped in a rectangular slide rail. A stabilizing block with a circular through hole is installed on the top of the rectangular slide rail. The toothed ring part of a small gear is movably engaged with a large gear. A connecting block is fixedly installed at the bottom of the large gear. One end of a support rod is movably installed on the side of the connecting block, and the other end of the support rod is installed on the slide rail. The stopper mold is placed in a clamping device for fixation. The crown gripper and the bottom gripper in the clamping device fix the crown and the bottom positions of the stopper mold. A rubber gasket is arranged at the bottom, which will not damage the stopper mold and stabilizes the position of the stopper mold, making the operation more convenient.

[0004] This device still has defects when in use. Firstly, the processing and positioning of the rubber raw material by this device are not accurate enough, which easily leads to non-standard contour shapes of the products. Secondly, the previous rubber material processing devices were not equipped with a detection mechanism, and the processed rubber products needed to be sent to a special detection device for another treatment, which was a waste of non-human resources. Summary of the Invention

[0005] The purpose of the present invention is to provide a molding device for processing butyl rubber stoppers in view of the deficiencies of the prior art. When this device is in use, the strip-shaped butyl rubber to be processed is put into the rear port of the insertion tube. The staff then installs the surrounding top rod on the side wall of the extension plate. The stepping 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, the nut block and the slider are driven to slide back and forth along the track of the guide rail. The extension plate and the surrounding top rod on its side wall will also slide with the slider and push the strip-shaped butyl rubber forward step by step. The strip-shaped butyl rubber stops every time it advances a unit distance. The cutting hydraulic press drives the blade to extend and insert into the knife groove to cut the strip-shaped butyl rubber into pieces of stoppers, so as to solve the problems mentioned in the background art.

[0006] To solve the above problems, the present invention provides the following technical solutions: A forming device for processing butyl rubber stoppers, including a fixed table and an insertion table.

On the side wall of the movable table, there is an ink dotting mechanism matching the cylindrical rubber material. At the top of the insertion table, there is..., and an insertion tube is inserted inside.... At the rear end of the insertion tube, there is an ink dotting horizontal groove. At the front end of the insertion tube, there is a cutting vertical groove. The ink dotting horizontal groove and the cutting vertical groove are perpendicular to each other.

At the bottom of the insertion table, a cutting hydraulic press is fixedly arranged. On the telescopic rod of the cutting hydraulic press, there is a blade. On the side wall of the insertion tube, there is a knife groove matching the blade.

[0007] During use, the strip-shaped butyl rubber to be processed is put into the rear port of the insertion tube. During the rotation of the threaded rod, it drives the nut block and the slider to slide back and forth along the track of the guide rail. The top rod mechanism will also slide with the slider and push the strip-shaped butyl rubber forward step by step. Every time the strip-shaped butyl rubber advances one unit distance inside the insertion tube and stops, the cutting hydraulic press drives the blade to extend out and insert into the knife groove to cut the strip-shaped butyl rubber into pieces of stoppers, realizing the function of efficient cutting.

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

[0009] During use, the staff installs the surrounding top rod on the side wall of the extension plate. The extension plate and the surrounding top rod on its side wall will also slide with the slider and push the strip-shaped butyl rubber forward step by step.

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

[0011] During use, during the process of assembling around the ejector rod, the ejector rod can be inserted from the position of the ink dotting transverse groove for assembly, which increases the speed of assembly.

[0012] Furthermore, a square block is provided at the lower end of the extension plate, a square hole matching the square block is provided at the end of the ejector rod around which it is wound, the material of the square block is iron metal, and a magnet sheet is provided inside the square hole at the end of the ejector rod around which it is wound.

[0013] During use, during the process of installing the ejector rod around which it is wound, align the square hole at the end of the ejector rod around which it is wound with the square block and insert it until the square block and the square hole are attracted together.

[0014] Furthermore, the torsion mechanism includes a stepping motor on the side wall of the fixed table, a reduction gear is installed on the rotating shaft of the stepping motor, a gear disc is further provided on the outer side wall of the threaded rod, and the gear disc meshes with the reduction gear.

[0015] During use, the stepping motor drives the gear disc to rotate through the reduction gear, the threaded rod rotates synchronously with the gear, and during the rotation of the threaded rod, it drives the nut block and the slider to slide back and forth along the track of the guide rail.

[0016] Furthermore, the ink dotting mechanism includes a movable table, an ink cartridge is provided on the front side wall of the movable table, a dotting tube is connected to the side wall of the ink cartridge, the end of the dotting tube is horizontally aligned with the notch of the ink dotting transverse groove, an ink pump is provided inside the ink cartridge, and the movable table is connected to the linkage mechanism.

[0017] During use, the ink cartridge and the dotting tube on the side wall of the movable table will be inserted from the ink dotting transverse groove to make a marked line segment on the side wall of the strip-shaped butyl rubber. Each cut rubber plunger will have a marked line segment. Workers can refer to the marked line segment to judge whether the length of each rubber plug meets the standard. The marked line segment can also be used as a reference standard for subsequent multi-channel processing techniques.

[0018] Furthermore, the linkage mechanism includes two cross bars fixedly provided on the side wall of the movable table, sliding holes matching the cross bars are provided on the side wall of the fixed table, the two cross bars are respectively inserted into the sliding holes on the side wall of the fixed table, a return spring is sleeved on the outer side of the cross bar, one end of the return spring is fixedly connected to the side wall of the movable table, the other end of the return spring is fixedly connected to the side wall of the fixed table, a cam is provided at the rear end of the threaded rod, a pick-up beam rod is provided on the rear side wall of the movable table, and an arc-shaped tile is provided at the outer end of the pick-up beam rod, and the arc-shaped tile abuts against the side wall of the cam.

[0019] During use, for every full rotation of the threaded rod, the cam at the end of the threaded rod will push the arc-shaped tile forward once. As a result, the movable table will move away from the fixed table once. Consequently, the movement of the ink dotting tube and the threaded rod is linked, which improves the accuracy of the ink dotting tube in drawing marking lines.

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

The extension plate and the surrounding ejector rod on its side wall will also slide with the slider and push the strip-shaped butyl rubber forward step by step. Each time the strip-shaped butyl rubber advances a unit distance and stops, the cutting hydraulic press drives the blade to extend and insert into the knife groove to cut the strip-shaped butyl rubber into pieces of bottle stoppers.

[0024] Secondly, for every full rotation of the threaded rod, the cam at the end of the threaded rod will push the arc-shaped tile forward once.

Each cut piece of rubber plunger will have a marked line segment. The staff can refer to the marked line segment to judge whether the length of each rubber stopper meets the standard. The marked line segment can also be used as a reference standard for subsequent multiple processing procedures. BRIEF DESCRIPTION OF THE DRAWINGS
