Description

Technical Field

[0001] This utility model relates to the field of page-separation inkjet printing, and in particular to a page-separation mechanism for a friction-type page-separation machine. 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 PU friction pads for paging. The lower surface of the friction pad engages with the paging belt at the bottom to paging stacked packaging bags for subsequent printing operations. The disadvantages are: the overall cost of the unit is relatively high, which may not meet the needs of some customers; the PU friction pads are thick and require custom molds, increasing costs; and the use of tension springs and other mechanisms to press the friction pads together results in high noise during operation; one end of the positioning rod is fixed inside the drive box on the side, preventing adjustment of the positioning rod's height and level, thus limiting the range of height adjustment of the friction pads, while the pressing mechanism cannot be horizontally adjusted along the friction pad's horizontal direction. Utility Model Content

[0004] The purpose of this invention is to provide a page-separating mechanism for a friction-type page-separating machine that solves the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a collating mechanism for a friction collating machine, comprising a frame, a collating belt, a friction pad, a pusher plate, a baffle plate, and a guide plate. Left and right supports are mounted on both sides of the frame, and a first positioning shaft, a second positioning shaft, and a third positioning shaft are mounted between the left and right supports. The first, second, and third positioning shafts are sequentially mounted from front to back along the material conveying direction. The guide plate is fixed to the middle of the first positioning shaft. The upper end of the friction pad is clamped and fixed to the middle of the second positioning shaft, and the lower end is tightly attached to the upper surface of the collating belt. A fine-tuning support is provided on the third positioning shaft. The fine-tuning support has a first pressure rod for adjusting the angle between the friction pad and the feed end of the collating belt, and a second pressure rod for adjusting the clamping force at the discharge end of the friction pad.

[0006] Preferably, the fine-tuning support is fixed to the middle of the third positioning shaft, the upper ends of the first and second pressure rods are provided with external threads, the front and rear ends of the fine-tuning support are provided with adjusting screw holes that match the external threads, the upper end of the first pressure rod is threadedly rotatably connected to the adjusting screw hole at the front end of the fine-tuning support, the upper end of the second pressure rod is threadedly rotatably connected to the adjusting screw hole at the rear end of the fine-tuning support, and the top ends of the first and second pressure rods are provided with handles.

[0007] Preferably, the two ends of the first positioning shaft are fixedly connected to the left and right brackets respectively.

[0008] Preferably, the left and right supports are provided with a first adjustment hole, which is located at both ends of the second positioning shaft. The two ends of the second positioning shaft are fixed to the left and right supports by fastening screws that match the first adjustment hole.

[0009] Preferably, the left and right supports are provided with a second adjustment hole horizontally, the second adjustment hole is located at both ends of the third positioning shaft, and the two ends of the third positioning shaft are fixed to the left and right supports by fastening screws that match the second adjustment hole.

[0010] Preferably, the friction pad has a double-layer structure, with a rubber layer as the lower layer and a nylon cloth as the upper layer.

[0011] Preferably, the frame is provided with lateral translation grooves for adjusting the baffle plate and the pusher plate.

[0012] Preferably, the front end of the baffle plate is fixed to the transverse translation groove by fastening bolts, and the rear end of the baffle plate is detachably connected to the third positioning shaft by a clamp.

[0013] Preferably, the pusher plate consists of an inclined plate and a Z-shaped base. The inclined plate is inclined toward the feed inlet between the plywood belt and the friction belt, and forms a discharge port with the guide plate. The upper top surface of the Z-shaped base is fixedly connected to the bottom surface of the inclined plate, and the lower bottom surface is fixed to the transverse translation groove by fastening bolts. The Z-shaped base is also provided with a longitudinal translation groove to facilitate the longitudinal translation of the fastening bolts.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] 1. In this utility model, the friction pad, guide plate, and fine-tuning mechanism are each mounted on an independent positioning shaft between the left and right supports, eliminating the need for complex pre-tightening structures such as tension springs. The pressure of the friction pad is directly adjusted by the first and second pressure rods on the fine-tuning support. The paging of the packaging bag is achieved by cooperating with the paging belt. The mounting of the left and right supports and the rigid connection structure of the first and second pressure rods ensure the overall structural stability of the paging mechanism, resulting in very low noise during paging operation.

[0016] 2. The angle between the friction pad and the feed inlet at the front end of the plywood belt can be adjusted by the first pressure bar to better feed the packaging bags. The second pressure bar can press the rear end of the friction pad, leaving a plywood gap for only one packaging bag to pass through. When a double-sheeted packaging bag passes under the second pressure bar, the upper and lower packaging bags can be separated to avoid overlapping or stacking, which would affect subsequent printing.

[0017] 3. Through improvements to the fine-tuning mechanism, even thinner friction skins can be well compressed and fine-tuned. This allows the present invention to replace the original, more expensive thick PU friction skin with a lower-cost friction skin, greatly reducing the mold opening and manufacturing costs of PU friction skins, and also providing excellent paging effects.

[0022] The present invention will be further described below.

[0023] Example: A page-separating mechanism for a friction-type page-separating machine, see [link / reference] Figures 1 to 3The machine includes a frame 1, a piecing belt 11, a friction pad 7, a pusher plate 8, a baffle plate 10, and a guide plate 9. Left and right supports 2 are mounted on both sides of the frame 1. A first positioning shaft 5, a second positioning shaft 4, and a third positioning shaft 3 are mounted between the left and right supports 2. The first positioning shaft 5, the second positioning shaft 4, and the third positioning shaft 3 are mounted sequentially from front to back along the material conveying direction. The guide plate 9 is fixed to the middle of the first positioning shaft 5. The upper end of the friction pad 7 is clamped and fixed to the middle of the second positioning shaft 4, and the lower end is tightly attached to the upper surface of the piecing belt 11. A fine-tuning support 6 is provided on the third positioning shaft 3. The fine-tuning support 6 is provided with a first pressure rod 12 for adjusting the angle between the feed end of the friction pad 7 and the piecing belt 11, and a second pressure rod 13 for adjusting the clamping force at the discharge end of the friction pad 7. In this invention, the friction pad 7, the guide plate 9, and the fine-tuning mechanism are each mounted on independent positioning shafts between the left and right supports 2, eliminating the need for complex pre-tightening structures such as tension springs. The friction pad 7 is directly pressed by the first pressure rod 12 and the second pressure rod 13 on the fine-tuning support 6. The paging of the packaging bag is achieved by cooperating with the paging belt 11. The mounting of the left and right supports 2 and the rigid connection structure of the first pressure rod 12 and the second pressure rod 13 ensure the overall structural stability of the paging mechanism, resulting in very low noise during paging operation.

[0024] The angle between the friction leather 7 and the feed inlet at the front end of the plywood belt 11 can be adjusted by the first pressure rod 12 to better feed the packaging bag. When the packaging is thin, the first pressure rod 12 can be pressed down, and the angle at the feed inlet is smaller, making it easier for thinner packaging bags to enter the rear plywood section. When the packaging bag is thick, the first pressure rod 12 can be raised to allow thicker packaging bags to enter the rear plywood section. The second pressure rod 13 can press the rear end of the friction leather 7, leaving a plywood gap for only one packaging bag to pass through. When the doubled packaging bag passes under the second pressure rod 13, after being pressed by the second pressure rod 13, the friction between the friction leather 7 and the upper packaging bag is greater than the friction between the overlapping packaging bags. The friction between the plywood belt 11 and the lower packaging bag will then drive the lower packaging bag forward to be discharged. Under the interaction of forces, the upper and lower packaging bags can be separated.

[0025] To achieve adjustment of the feed end and the pagination outlet of the friction pad 7, a fine-tuning mechanism was specifically designed. The fine-tuning support 6 is fixed to the middle of the third positioning shaft 3. The upper ends of the first pressure rod 12 and the second pressure rod 13 are provided with external threads. The front and rear ends of the fine-tuning support 6 are provided with adjusting screw holes that match the external threads. The upper end of the first pressure rod 12 is threadedly rotatably connected to the adjusting screw hole at the front end of the fine-tuning support 6, and the upper end of the second pressure rod 13 is threadedly rotatably connected to the adjusting screw hole at the rear end of the fine-tuning support 6. The top ends of the first pressure rod 12 and the second pressure rod 13 are each provided with a handle 14. When the handle 14 on the first pressure rod 12 is rotated clockwise, the first pressure rod 12 will press against the feed inlet in the middle of the friction pad 7, at which time the included angle of the feed inlet decreases; conversely, when the handle 14 on the first pressure rod 12 is rotated counterclockwise, the first pressure rod 12 rises, and the included angle increases. The second pressure rod 13 is used to adjust the page gap according to the product thickness. When the handle 14 on the second pressure rod 13 is turned clockwise, the second pressure rod 13 is pressed down, and the page gap decreases. Conversely, when the handle 14 on the second pressure rod 13 is turned counterclockwise, the second pressure rod 13 is raised, and the page gap increases.

[0026] Since the first positioning shaft 5 is used to install the guide plate 9, the discharge port between the guide plate 9 and the push plate 8 can be adjusted by the push plate 8 according to product needs. Therefore, the first positioning shaft 5 can be directly fixed on the left and right brackets 2, and the two ends of the first positioning shaft 5 are respectively fixedly connected to the left and right brackets 2.

[0027] The left and right brackets 2 are vertically provided with first adjustment holes 22, which are located at both ends of the second positioning shaft 4. The two ends of the second positioning shaft 4 are fixed to the left and right brackets 2 by fastening screws that match the first adjustment holes 22. Through the vertically provided first adjustment holes 22, the installation height of the second positioning shaft 4 can be adjusted according to product needs, thereby allowing for significant adjustment of the angle between the friction pad 7 and the feed inlet of the plywood belt 11 to meet the needs of different products. Once the second positioning shaft 4 is adjusted to the corresponding height, it can be locked and fixed to the left and right brackets 2 by fastening screws.

[0028] The left and right supports 2 are horizontally provided with second adjustment holes 21, which are located at both ends of the third positioning shaft 3. The two ends of the third positioning shaft 3 are fixed to the left and right supports 2 by fastening screws that match the second adjustment holes 21. For some products that are long, the lower end of the second pressure rod 13 can be adjusted horizontally through the second adjustment holes 21 to better facilitate page splitting.

[0029] Thanks to the improvement of the fine-tuning mechanism, even the thinner friction skin 7 can be well compressed and fine-tuned. This utility model uses a lower-cost friction skin 7 to replace the original higher-cost PU thick friction skin 7. The friction skin 7 has a double-layer structure, with a rubber layer on the bottom and a nylon cloth on the top, which is a conventional conveyor belt. The lower rubber layer can be used as a friction layer, and the upper nylon cloth can provide the friction skin 7 with good tensile strength, which greatly reduces the mold opening cost and manufacturing cost of the PU friction skin 7.

[0030] To meet the paging needs of packaging bags of different sizes, the frame 1 is provided with a transverse translation groove 15 for adjusting the baffle plate 10 and the pusher plate 8.

[0031] The front end of the baffle plate 10 is fixed to the transverse translation groove 15 by fastening bolts. The rear end of the baffle plate 10 is detachably connected to the third positioning shaft 3 by a clamp. By opening the clamp at the rear end of the baffle plate 10, the baffle plate 10 can be moved laterally along the transverse translation groove 15. After it is moved into place, the rear end can be fixed to the third positioning shaft 3 by the clamp to suit the width requirements of different products.

[0032] The pusher plate 8 consists of an inclined plate 91 and a Z-shaped base 92. The inclined plate 91 is inclined towards the feed inlet between the plywood belt 11 and the friction belt 7, and forms a discharge port with the guide plate 9. The upper top surface of the Z-shaped base 92 is fixedly connected to the bottom surface of the inclined plate 91, and the lower bottom surface is fixed to the transverse translation groove 15 by fastening bolts. The Z-shaped base 92 is also provided with a longitudinal translation groove 16 to facilitate the longitudinal translation of the fastening bolts. After loosening the fastening bolts on the Z-shaped base 92, the position of the pusher plate 8 can be adjusted laterally through the transverse translation groove 15, and the front and rear position of the pusher plate 8 can be adjusted through the longitudinal translation groove 16 to meet the needs of products of different sizes.
