Description

[Technical Field]

[0001] This invention relates to the field of plastic flowers, and more particularly to a plastic flower bouquet forming apparatus. [Background Technology]

[0002] Plastic flowers are made by molding flower-shaped plastic at one end of an iron core and fixing the ends of multiple plastic flowers together to form a plastic bouquet. Currently, plastic flower bouquets are made by manually winding the ends of the plastic flowers together with plastic thread. This method of manually winding plastic thread to make plastic flower bouquets is inefficient and has high labor costs.

[0010] Preferably, the frame is also fixed with a material dispensing and positioning cylinder that works in conjunction with the material picking tongue plate, and the piston rod of the material dispensing and positioning cylinder is fixed with a material dispensing and positioning plate at its end.

[0011] Preferably, the molding machine includes a molding die, and the molding die is provided with a plurality of positioning holes.

[0013] Preferably, the output end of the de-branching motor is fixed with a de-branching drive wheel, and the frame is provided with a de-branching driven wheel that is rotatably connected to the frame. The de-branching driven wheel is connected to the aforementioned de-branching drive wheel through a de-branching timing belt, and the de-branching timing belt is fixed to the aforementioned de-branching slide plate.

The pruning slide is driven to move on the frame by a pruning transverse motor and a pruning transverse lead screw. A pruning slide plate is mounted above the pruning slide and is driven to move up and down on the pruning slide by a pruning vertical motor. A pruning panel is also mounted above the pruning slide plate and is driven to move by a pruning longitudinal motor and a pruning rack fixed on the pruning slide plate. Pruning fixing slots are evenly distributed on one side of the upper end of the pruning panel, and pruning sliders are mounted on the other side of the upper end of the pruning panel. Pruning sliders are driven to move on the pruning panel by a pruning motor. Pruning pushers are fixed on the pruning sliders at positions corresponding to the pruning fixing slots.

[0015] Preferably, the transfer mechanism includes a transfer cylinder fixed on the frame, and the piston rod of the transfer cylinder is symmetrically fixed with claw plates at both ends, and the upper end of the claw plates is uniformly provided with claw plate positioning grooves.

[0016] Working Principle: Cut iron skewers are poured into two separate material boxes. The skewers slide along the guide plate to the bottom of the guide plate where the material wheel is positioned. Due to the attraction of the magnet in the material distribution groove, one skewer is horizontally fixed inside the groove. The material distribution motor drives the material distribution rotating shaft to rotate, and the material distribution wheel rotates with the shaft. The skewer rotates with the wheel, and when it reaches the material distribution fixing groove on the picking tongue plate, it is engaged in the groove. The material distribution motor then drives the material distribution rotating shaft to rotate in the opposite direction, and the material distribution groove on the wheel returns to the material box. The next skewer enters the material distribution groove again, the tongue plate motor starts, and the tongue plate gear rotates, moving the picking tongue plate. The next material distribution fixing groove on the picking tongue plate reaches the designated position, and the material distribution motor drives the material distribution rotating shaft to rotate again, and the skewer is engaged in the material distribution groove once more. Within the fixed slot, the process operates in a cyclical manner. Once a certain number of iron skewers are fixed on the material-receiving tongue plate, the material-distributing positioning cylinder is activated, causing the material-distributing positioning plate to move. After the material-distributing positioning plate contacts one end of the iron skewers on the material-receiving tongue plate, it pushes each iron skewer to move. After the iron skewers are neatly arranged, the material-distributing positioning plate separates from the iron skewers. The transfer cylinder is then activated, extending the piston rod and raising the claw plates. Both ends of each iron skewer are respectively engaged in the claw plate positioning grooves of the two claw plates. The claw plates continue to rise, separating the iron skewers from the material-receiving tongue plate. The tongue plate motor drives the tongue plate gear to rotate in the opposite direction, returning the material-receiving tongue plate to its initial position. The transfer cylinder is activated again, shortening the piston rod and lowering the claw plates. The iron skewers descend with the claw plates, and after each iron skewer is engaged in the corresponding branch fixing groove on the branch insertion panel, the iron skewers separate from the claw plates. The branch traversing motor then drives... When the horizontal lead screw rotates, the insertion slide moves as the screw rotates. The insertion panel moves with the slide to the designated position, at which point the horizontal motor stops and the vertical motor starts. The vertical motor drives the vertical lead screw to rotate. Since the vertical lead screw is threaded to the sliding plate, the sliding plate moves vertically. When the iron skewer is aligned with a row of positioning holes on the forming machine, the vertical motor stops and the longitudinal motor starts. The longitudinal motor drives the insertion gear to rotate. Because the gear meshes with a fixed rack on the insertion panel, the rotation of the gear moves the panel, causing the iron skewer to move closer to the positioning hole. Once the iron skewer reaches the designated position, the vertical motor starts. The insertion slider moves on the insertion panel, and the insertion pusher fixed on the slider moves with it. After the pusher contacts one end of the skewer, it pushes the skewer into the positioning hole. Once the skewer is inserted into the forming mold, the insertion panel separates from the skewer, and the panel returns to its initial position. The offset rod cylinder starts, and its piston moves, causing the lifting rod to move. After one end of the lifting rod is inserted into the lifting positioning groove of the lifting plate, the offset motor starts, and the offset slide plate and slider move upward. The lifting rod moves with the slide plate, and after contacting the end of the skewer, it bends the skewer. The next insertion mechanism inserts the skewer into the next row of positioning holes in the forming mold, and then the offset rod cylinder starts again, its piston moving once more.The lifting pole separates from the iron skewer, the branch-lifting motor restarts, and drives the branch-lifting slide and slider downwards. The branch-lifting long rod cylinder starts, and its piston moves again, bringing the lifting pole back below the iron skewer. The lifting pole then lifts the iron skewer again, and the next branch-inserting mechanism inserts the iron skewer into the next row of positioning holes in the forming mold. This cycle repeats until all positioning holes in the forming mold are filled with iron skewer. The forming machine starts, injecting molten plastic into the mold. After the plastic cools, the ends of the iron skewer are fixed together by the plastic. The clamping motor starts, and the upper and lower clamping plates move towards each other. After contact, the iron skewer is fixed between the upper and lower clamping plates. Once the iron skewer is gripped by the upper and lower clamping plates, the forming mold opens, the branch-removing motor starts, and drives the branch-removing slide. The upper and lower clamping plates move, and the formed iron skewers move with the de-branching slide plate. After the iron skewers separate from the forming mold, the sprue vertical movement motor starts, and the sprue slide plate moves downward. After the sprue slide plate reaches the designated position, the sprue cylinder starts, the piston rod of the sprue cylinder extends, and the hook descends. After the hook inserts between two adjacent bundles of iron skewers, the sprue horizontal movement motor starts, and the sprue horizontal movement motor drives the sprue slide to move. The hook moves with the sprue slide, and after the hook contacts the injection sprue, it removes the sprue from the formed iron skewer bundle. After the sprue is removed, the formed iron skewers are collected. This process is repeated. This device can form iron skewers from single iron skewers into bundles, and injection mold the tail of the iron skewers bundles to fix them into a bundle. It realizes the automated production of iron skewer bouquets, greatly improves the production efficiency of plastic flowers, and reduces labor costs.

[0017] Compared with existing technologies, the present invention has the following advantages:

[0018] This device can form a bundle of iron skewers from a single skewer, and then injection mold the tail of the bundle to fix the skewers into a bundle, thus realizing the automated production of iron skewer bouquets, greatly improving the production efficiency of plastic flowers and reducing labor costs.
