Technical Field
[0001] This utility model relates to the field of page-separation inkjet printing, and in particular to a friction-blocking page-separation mechanism. Background Technology
[0002] During the packaging coding process, stacks of plastic bags, packaging bags, paper boxes or cards of various specifications need to be automatically separated by a folding machine and individually conveyed to a conveyor belt for easy printing by a coding machine or laser machine to print production dates, batch numbers, anti-counterfeiting marks, patterns, etc.
[0003] Existing friction-type paging mechanisms all use friction pads for paging. The lower surface of the friction pad engages with the surface of the paging belt at the bottom to separate stacked packaging bags for subsequent printing operations. The disadvantages are that the friction pads are consumable parts and easily wear down, requiring frequent replacement; otherwise, paging accuracy will be affected, and overlapping or duplicate sheets may occur. Furthermore, the friction pads rub against the packaging bag surface in a surface-to-surface manner, which can generate noise during rapid paging. Utility Model Content
[0004] The purpose of this invention is to provide a blocking friction-type paging mechanism that solves the above-mentioned problems.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a blocking friction type paging mechanism, including a paging head and a paging belt. The paging head is composed of a support, a pressure tongue block, a pressure tongue mounting seat, a baffle plate, and a pressure plate. The pressure tongue block is fixed to the bottom of the pressure tongue mounting seat. The upper part of the back of the pressure tongue mounting seat is slidably connected to the support. The baffle plate is located on the front of the pressure tongue mounting seat and is fixedly connected to the support. The pressure plate is fixed to the lower part of the back of the pressure tongue mounting seat.
[0006] Preferably, the tongue depressor is a polyurethane tongue depressor, which is wider at the top and narrower at the bottom, with an arc-shaped front and a vertical back, the arc-shaped front facing the product feeding direction.
[0007] Preferably, the upper end of the tongue depressor is provided with a connecting part, and the bottom surface of the tongue depressor mounting base is provided with a notch that matches the connecting part. The connecting part is fixed to the notch at the bottom of the tongue depressor mounting base by fastening screws.
[0008] Preferably, the support is also provided with a fine-tuning mechanism for adjusting the height of the pressure tongue. The fine-tuning mechanism consists of a screw, a screw sleeve, and a digital position display. The screw sleeve is fixed to the top of the pressure tongue mounting base, the bottom of the digital position display is fixed to the top of the support, the rotating shaft of the digital position display is fixedly connected to the upper part of the screw, the upper end of the screw is provided with a handle, and the lower end passes through the digital position display and the support and is threadedly rotatably connected to the screw sleeve at the top of the pressure tongue mounting base.
[0009] Preferably, the support is provided with a vertical slide rail on the front, and the tongue mounting seat is slidably connected to the support through the slide rail.
[0010] Preferably, the upper part of the baffle plate is vertically arranged, and the lower part is inclined towards the bottom of the pressure tongue block.
[0011] Preferably, the pressure plate is L-shaped, with the vertical panel closely attached to the back of the pressure tongue block and the pressure tongue mounting base, and the horizontal panel extending horizontally along the product discharge direction.
[0012] Preferably, both the baffle plate and the pressure plate are provided with adjustable holes for adjustable installation height and locking screws.

[0015] Compared with the prior art, the advantages of this utility model are:
[0016] 1. This utility model proposes a brand-new paging method, which uses a polyurethane pressure tongue block to replace the existing friction skin, and can also achieve rapid paging of packaging bags. Not only is the paging effect good, but the paging process is also almost noiseless. Furthermore, the polyurethane pressure tongue block not only has good friction but is also sturdy and durable, and can not be replaced for several years, which greatly solves the maintenance cost and saves maintenance time.
[0017] 2. The fine-tuning mechanism allows for adjustment of the mounting height of the pressure bar, thus adjusting the page spacing and enabling single-page paging. Furthermore, a digital position display is added to the fine-tuning mechanism, which detects and displays the amount of screw rotation, thereby determining the adjusted lifting height of the pressure bar on the pressure bar mounting base. This allows staff to quickly adjust the adjusting screw to the correct position during subsequent adjustments, eliminating the need for repeated page-page adjustments.
[0018] 3. To enable better paging by the tongue depressor, the baffle plate and pressure plate were designed to facilitate better paging operations, allowing for single-sheet feeding and single-sheet discharging of packaging bags. The height of the baffle plate and pressure plate can be individually installed and adjusted as needed. Attached Figure Description

[0024] The present invention will be further described below.
[0025] Example: A friction-blocking paging mechanism, see [link / reference] Figure 1-Figure 4 The system includes a page divider head 2 and a page divider belt 1. The page divider head 2 is installed above the page divider belt 1 of the page divider machine. A page divider gap, allowing only one sheet of product to pass through, is left between the pressure tongue block 3 and the page divider belt 1. The page divider head 2 consists of a support 5, a pressure tongue block 3, a pressure tongue mounting base 4, a baffle plate 6, and a pressure plate 7. The pressure tongue block 3 is fixed to the bottom of the pressure tongue mounting base 4. The upper back of the pressure tongue mounting base 4 is slidably connected to the support 5. The pressure tongue mounting base 4 serves as the mounting component for the pressure tongue block 3. The height of the tongue-pressing block 3 can be adjusted by sliding connection with the support 5. The baffle plate 6 is located on the front of the tongue-pressing mounting base 4 and is fixedly connected to the support 5. The baffle plate 6 acts as a material stopper and, together with the page-separating wheel, guides a small amount of the stacked packaging bags to the bottom of the tongue-pressing block 3. The page-separating gap between the tongue-pressing block 3 and the page-separating belt 1 can be adjusted so that only a single packaging bag can be separated. The pressing plate 7 is fixed to the lower back of the tongue-pressing mounting base 4. The separated packaging bags are pressed out by the pressing plate 7 in conjunction with the page-separating belt 1.
[0026] This invention employs a novel paging method, utilizing a polyurethane pressure tongue block 3 to replace the existing friction pad. This achieves the same rapid paging of the packaging bag, offering not only superior paging performance but also minimizing the friction area with the packaging bag, resulting in virtually no noise during the paging process. Furthermore, the polyurethane pressure tongue block 3 is not only highly frictional but also robust and durable, requiring no replacement for several years, significantly reducing maintenance costs and saving maintenance time.
[0027] The tongue depressor block 3 is a polyurethane tongue depressor block 3. The polyurethane tongue depressor block 3 not only has good friction but is also sturdy and durable. Although it will experience some wear after long-term use, it can be used for a long time without needing replacement for several years by adjusting its height. The tongue depressor block 3 has a locking tongue shape, wider at the top and narrower at the bottom. Its front is an arc-shaped surface 31, and its back is a vertical surface 32. The arc-shaped surface 31 faces the product feeding direction. The locking tongue design facilitates the entry of stacked packaging bags into the bottom of the tongue depressor block 3 for paging. Moreover, compared to existing friction pads, the block-shaped tongue depressor block 3 has better structural stability after installation and fixation, making the paging process more stable.
[0028] The upper end of the tongue depressor block 3 is provided with a connecting part 33, and the bottom surface of the tongue depressor mounting base 4 is provided with a notch 41 that matches the connecting part 33. The connecting part 33 is fixed in the notch 41 at the bottom of the tongue depressor mounting base 4 by fastening screws. Through the cooperation of the connecting part 33 and the notch 41, the upper end of the tongue depressor block 3 can be tightly fixed to the bottom of the tongue depressor mounting base 4.
[0029] The support 5 is also equipped with a fine-tuning mechanism for adjusting the height of the tongue depressor. This mechanism consists of a screw 11, a screw sleeve 12, and a digital position display 8. The screw sleeve 12 is fixed to the top of the tongue depressor mounting base 4, and the bottom of the digital position display 8 is fixed to the top of the support 5. The rotating shaft of the digital position display 8 is fixedly connected to the upper part of the screw 11. The upper end of the screw 11 has a handle 9, and the lower end passes through the digital position display 8 and the support 5, and is threadedly connected to the screw sleeve 12 at the top of the tongue depressor mounting base 4. During adjustment: simply rotate the handle 9 at the upper end of the screw 11 to rotate the screw 11, which in turn moves the tongue depressor mounting base 4 up and down via the screw sleeve 12, thus adjusting the height of the tongue depressor block 3. Simultaneously, the digital position display 8 records the movement of the tongue depressor mounting base. Through the design of this fine-tuning mechanism, the installation height of the tongue depressor block 3 can be adjusted to regulate its page spacing and achieve single-page paging. Furthermore, a digital position display 8 is added to the fine-tuning mechanism. The rotation amount of the screw 11 can be detected and displayed through the digital position display 8, thereby determining the adjusted lifting height of the pressure block 3 on the pressure tongue mounting seat 4. This allows the staff to quickly adjust the adjusting screw 11 to the correct position during the next adjustment without having to repeatedly perform page adjustments.
[0030] The support 5 is vertically equipped with a slide rail 10 on its front side, which enables a sliding connection between the tongue-pressing mounting base 4 and the support 5. The upper part of the baffle plate 6 is vertically arranged, and the lower part is inclined towards the bottom of the tongue-pressing block 3. The baffle plate 6 serves to stop the material, and at the same time, as the ply belt 1 rotates, it guides the stacked packaging bags to the bottom of the tongue-pressing block 3.
[0031] The pressing plate 7 is L-shaped, with its vertical surface 32 tightly attached to the back of the pressing tongue block 3 and the pressing tongue mounting base 4. The horizontal panel extends horizontally along the product discharge direction. The vertical part of the pressing plate 7 is not only used for installation with the pressing tongue mounting base 4, but also tightly attached to the back of the pressing tongue block 3 to reduce its horizontal plastic deformation, so that the pressing tongue block 3 can better act on the surface of the packaging bag. Its horizontal part facilitates pressing and discharging, so that the paginated packaging bag can be better transported to the next stage.
[0032] To achieve better paging of the tongue depressor block 3, this utility model designs the baffle plate 6 and the pressure plate 7 to facilitate better paging operations, enabling single-sheet feeding and single-sheet discharging of packaging bags. Simultaneously, the heights of the baffle plate 6 and the pressure plate 7 can be individually adjusted as needed, as follows: both the baffle plate 6 and the pressure plate 7 are equipped with adjustable holes and locking screws for height adjustment. The baffle plate 6 is fixedly connected to the support 5 via the locking screws, and the pressure plate 7 is fixedly connected to the tongue depressor mounting base 4 via the locking screws.
[0033] Both the support 5 and the tongue-pressing mounting base 4 are made of aluminum alloy profiles. The structural stability of tubular materials is relatively poor, while aluminum alloy profiles have high structural strength and good stability, which is more conducive to the lifting and positioning of the tongue-pressing block 3, making the paging gap between the tongue-pressing block 3 and the paging belt 1 more stable and the paging effect better.
[0034] The foregoing has provided a detailed description of the friction-blocking paging mechanism of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, based on the idea of this utility model, there will be changes in the specific implementation and application scope. Changes and improvements to this utility model are possible without exceeding the concept and scope specified in the appended claims. Therefore, the content of this specification should not be construed as a limitation of this utility model.
