Abstract
Description
Technical Field
[0001] The utility model relates to the field of taking out finished products from die-cut products, in particular to an upper die plate changing device of a product taking machine. Background Art
[0002] A product removal machine is an automated device specifically designed for the post-processing of printing and packaging. It primarily removes the useful portion (finished product) from the waste edge of die-cut paper. To accommodate diverse die-cutting requirements, the die is typically designed with sufficient through-holes for the installation or passage of upper ejector pins. In existing technologies, when the upper die of a product removal machine automatically adjusts its needles to the shape of the waste edge, needles often become stuck. This results in the upper ejector pins being misaligned with the waste edge shape, preventing smooth removal of finished products and impacting yield. Summary of the Invention
[0003] The utility model aims at the shortcomings of the prior art and provides an upper die plate changing device for a product taking machine, which can reduce the occurrence of needle jamming.
[0004] The upper mold plate changing device of the product taking machine includes a frame, a drive mounting seat, an upper honeycomb panel and a honeycomb mold support plate; the frame has a mounting column, and a drive mounting seat with a power source is slidably provided on the mounting column; the drive mounting seat has an upper honeycomb panel at the bottom; the upper honeycomb panel includes a plurality of upper through holes for installing upper ejectors, and a honeycomb mold support plate is also provided below the upper honeycomb panel; the honeycomb mold support plate is equipped with lower through holes, and the upper through holes and the lower through holes are arranged correspondingly. The upper part of the honeycomb mold support plate is an avoidance space, and the lower part is a working space. The honeycomb mold support plate has four connection points, and the honeycomb mold support plate is connected to the four-point drive component that drives the honeycomb mold support plate to move up and down relative to the upper honeycomb panel through the connection points.
[0005] During the product removal process, it was found that the honeycomb mold pallet would tilt during the upward movement, causing the honeycomb mold pallet to come into hard contact with the upper ejector pin, resulting in pin jamming and even upper ejector pin loss, which increased costs. Therefore, the utility model adopts a four-point driving component to connect the four positions of the honeycomb mold pallet, driving the honeycomb mold pallet to maintain a horizontal state and rise steadily, avoiding pin jamming and ensuring smooth needle adjustment.
[0006] Preferably, a connecting piece is provided at the connection point, and four groups of the connecting pieces are symmetrically arranged on both sides of the honeycomb mold support plate, or the four groups of the connecting pieces are symmetrically arranged along the edge of the honeycomb mold support plate; when working, the connecting piece is coupled with the four-point driving component.
[0007] On the basis of having a connecting piece, the four-point driving component includes four sets of lifting power sources, and the connecting piece is transmission-connected with the lifting power source. The connecting piece is respectively provided with a lifting power source to drive the connecting piece to move upward to adjust the needle.
[0008] In addition to the connectors, the four-point drive assembly includes a swing support block that swings onto the frame. Four sets of connectors are positioned on either side of the honeycomb die tray, with the swing support blocks correspondingly positioned below the connector blocks. During needle adjustment, the drive mount lowers the honeycomb die tray, causing the swing support block to abut against the connectors, resulting in relative motion between the drive mount and the honeycomb die tray, completing the needle adjustment process.
[0009] Preferably, the drive mounting base includes a relief cavity with an opening at the top end thereof. A pin pressure plate is provided at the opening to abut against the top end of the upper ejector. To prevent dust, paper scraps, or burrs in the lower through-hole from preventing the upper ejector from descending smoothly, the pin pressure plate applies a certain amount of pressure to the upper ejector, ensuring that the upper ejector in need can smoothly enter the working space while the upper ejector in need remains in the relief cavity.
[0010] The ejector plate is provided with a driving connection to a vibration component, which is arranged outside the ejector plate. The vibration component drives the ejector plate to vibrate, further ensuring that the upper ejector in the working state falls smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.
[0019] The upper mold plate changing device of the sample extraction machine includes a frame 1, a drive mounting base 2, an upper honeycomb panel 3, and a honeycomb mold support plate 4. The frame 1 has a mounting post 11, on which a drive mounting base 2 with a power source is slidably mounted. The drive mounting base 2 has an upper honeycomb panel 3 at its bottom. The upper honeycomb panel 3 includes a plurality of upper through-holes for mounting upper ejectors 5. The upper ejectors 5 are installed in the upper through-holes, and gravity causes the upper ejectors 5 to hang downward. A honeycomb mold support plate 4 is also provided below the upper honeycomb panel 3. The honeycomb mold support plate 4 is equipped with lower through-holes, which are arranged in a corresponding manner with the lower through-holes. The upper part of the honeycomb mold support plate 4 is an escape space, and the lower part is a working space. During the sample extraction process, the upper ejectors 5 that are not in use enter the escape space, while the upper ejectors 5 that are in use enter the working space. The honeycomb mold pallet 4 has four connection points, which are connected to the four-point drive component 6 that drives the honeycomb mold pallet 4 to move up and down relative to the upper honeycomb panel 3. The specific distribution of the connection points can be various. For example, the honeycomb mold pallet 4 has four groups of connectors 41, which are symmetrically arranged on both sides of the honeycomb mold pallet 4, that is, the connectors 41 are arranged in pairs on both sides of the honeycomb mold pallet 4, or the four groups of connectors 41 are symmetrically arranged along the edge of the honeycomb mold pallet 4, that is, the four groups of connectors 41 are symmetrically arranged around the honeycomb mold pallet 4. During operation, the connectors 41 are coupled with the four-point drive component 6 to maintain the honeycomb mold pallet 4 in a horizontal state and move it upward evenly. When adjusting the needle, a scrap honeycomb mold is placed on the honeycomb mold support plate 4. The hole distribution of the scrap honeycomb mold is consistent with the lower through-hole distribution of the honeycomb mold support plate 4. The holes of the scrap honeycomb mold corresponding to the finished product position are sealed according to the shape of the finished product. The four-point driving component 6 drives the honeycomb mold support plate 4 to move upward, and the honeycomb mold support plate 4 drives the scrap honeycomb mold to move upward, so that the upper ejector pin 5 of the finished product part enters the avoidance space, and the upper ejector pin 5 of the scrap part passes through the lower through-hole and enters the working space.
[0020] There are multiple ways for the four-point drive component 6 to drive the honeycomb mold pallet 4 upward. For example, the four-point drive component 6 is four sets of lifting power sources, the connecting member 41 is transmission-connected to the lifting power source, and the connecting member 41 corresponds to the lifting power source one-to-one. By installing the lifting power source at the four connection points of the honeycomb mold pallet 4, these four sets of lifting power sources operate synchronously, ensuring that the honeycomb mold pallet 4 always remains horizontal during the vertical ascent process, avoiding the situation where the honeycomb mold pallet 4 is stuck due to the tilt of the honeycomb mold pallet 4. Alternatively, the four-point drive component 6 includes a swing support block 61, the swing support block 61 is swingably set on the frame 1, the swing support block 61 is rotatably set on the fixed seat, and the fixed seat is set between the mounting columns 11 of the frame 1. The four sets of connecting members 41 are respectively set on both sides of the honeycomb mold pallet 4, and the swing support blocks 61 are respectively set below the connecting blocks. The swing support block 61 can be manually rotated or driven to swing by a connecting rod assembly. In the two embodiments of simultaneously providing four sets of lifting power sources and supporting the honeycomb die plate 4 via a swing support block 61, it is preferred that the four-point drive component 6 be a swing support block 61, as this technical solution has a more reasonable mechanical layout. Furthermore, based on the swing support block 61, to ensure the normal operation of the honeycomb die plate 4 during the product removal process, positioning power sources 9 are provided on both sides of the drive mounting base 2. The positioning power sources 9 are connected to the honeycomb die plate 4. After adjustment is completed, the positioning power sources 9 maintain the relative position between the honeycomb die plate 4 and the upper honeycomb panel 3 unchanged. The above-mentioned power source can be a cylinder or a motor, etc., and those skilled in the art can select the appropriate power source according to their needs.
[0021] The lower through hole of the honeycomb die support plate 4 may have burrs due to processing reasons, or dust, paper scraps and other accumulations may accumulate in the lower through hole during long-term use of the equipment, causing the pin to get stuck. In order to ensure that the upper ejector 5, which should be in the working space, falls smoothly and avoids the pin getting stuck, the drive mounting base 2 has an escape cavity 21. The top of the escape cavity 21 is open, and an ejector pressure plate 7 is provided at the opening to abut the top of the upper ejector 5. A step is provided inside the drive mounting base 2, and the ejector pressure plate 7 is mounted on the step. The bottom of the ejector pressure plate 7 contacts the upper surface of the upper ejector 5 in the escape cavity 21 and applies appropriate pressure to promote the smooth descent of the upper ejector 5. To further prevent pin jams, the ejector plate 7 is in transmission connection with a vibrating component 8, which is positioned outside the plate. A gap exists between the plate and the inner wall of the drive mounting base 2. This gap allows the plate to vibrate. The vibration of the plate causes the upper ejector 5 to slightly move, while the upper ejector 5's own gravity causes it to fall smoothly. This is to generate vibration in the plate 7. The vibrating component 8 can be an electromagnetic vibrator or a reciprocating vibrator, as is known in the art.
[0022] Example 1
[0023] When the upper die of the sample extraction machine is in the plate-changing state, the upper ejector pins 5 are suspended in the upper through-holes of the upper honeycomb plate 3. A gap exists between the upper ejector pins 5 and the honeycomb die holder 4, through which the scrap honeycomb die is placed. Subsequently, four lifting power sources connected to the honeycomb die holder 4 drive the honeycomb die holder 4 upward, allowing the upper ejector pins 5 corresponding to the scrap portion to pass through the holes in the scrap honeycomb die and enter the working space. The holes in the scrap honeycomb die corresponding to the finished product are sealed, allowing the upper ejector pins 5 corresponding to the finished product to enter the avoidance cavity 21 of the drive mounting base 2.
[0024] When there are burrs, dust, or other obstructions inside the honeycomb die holder 4, the honeycomb die holder 4 will drive the upper ejector 5, which should be in working condition, to rise. When the upper ejector 5 abuts the ejector pressure plate 7, the ejector pressure plate 7 applies a certain amount of pressure to the upper ejector 5 to make it fall. If the upper ejector 5 still cannot fall, the vibrating component 8 drives the ejector pressure plate 7 to vibrate, and the vibration causes the upper ejector 5 to fall smoothly. After the upper die plate is replaced, the lifting power source can also position the honeycomb die holder 4.
[0025] Example 2
[0026] When the upper die of the sample extraction machine is in the plate-changing state, the swing support block 61 abuts against the connector 41 of the mold honeycomb panel, and the upper ejector pin 5 is suspended in the upper through-hole of the upper honeycomb panel 3. A gap exists between the upper ejector pin 5 and the honeycomb mold support plate 4, and the scrap honeycomb mold is placed on the honeycomb mold support plate 4 through the gap fit. Subsequently, the drive mounting base 2 moves downward, and due to the swing support block 61 supporting the mold honeycomb panel, the mold honeycomb panel moves upward relative to the upper honeycomb panel 3, bringing the mold honeycomb panel and the upper honeycomb panel 3 closer to each other. The upper ejector pin 5 corresponding to the scrap portion passes through the hole of the scrap honeycomb mold and enters the working space. The hole of the scrap honeycomb mold corresponding to the finished product is sealed, so that the upper ejector pin 5 corresponding to the finished product enters the avoidance cavity 21 of the drive mounting base 2.
[0027] The ejector plate 7 and the vibrating component 8 cooperate to ensure that the upper ejectors 5 corresponding to the waste edge are all within the working space. After the upper mold plate is replaced, the positioning power source 9 maintains the relative position of the honeycomb mold plate 4 and the upper honeycomb plate 3, driving the mounting base 2 to carry the honeycomb mold plate 4 upward and back to its original position. The swing power source drives the swing support block 61 to swing, avoiding the subsequent product removal work.
