Description

Technical Field

[0001] This utility model relates to the field of printing processing technology, specifically to a printing and packaging device for printing materials. Background Technology

[0002] Printed materials, including printed books, newspapers, and pictures, are a general term for various printed products produced using printing technology. In the production of some printed materials that do not require binding, the paper sheets need to be packaged to prevent them from scattering and being damaged during transportation and storage. Therefore, a packaging device for printed materials is needed. A Chinese utility model patent (publication number: CN220663138U) discloses a packaging device for printed materials. This device uses a conveyor frame, guide plate, and aligning plate in conjunction with auxiliary plates to align the front and back sides and left and right sides of the printed materials, ensuring the structural stability of the packaged printed materials. Simultaneously, during the aligning process, the upper surface of the printed materials is limited by the limiting plate, resulting in better packaging after alignment and effectively preventing the paper sheets from loosening and falling off during transportation and handling, thus avoiding damage.

[0003] In this solution, the limiting plate restricts the top of the packaged items to prevent the upper items from falling. However, the limiting plate is used in conjunction with a spring. If the initial spring force is preset too high, or if it is not precisely matched according to the thickness of the printed matter during adjustment, the downward pressure applied by the spring may exceed the paper's tolerance for thin printed matter (such as single sheets of paper or thin booklets), resulting in paper indentations, wrinkles, or even damage to the printed pattern. If it is a multi-layered stack of thin paper, the overly tight limiting may also cause the paper to stick together, affecting the subsequent retrieval after packaging. Therefore, a printing and packaging device for printed matter is needed to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a printing and packaging device for printed materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A printing and packaging device includes a support frame, a packaging mechanism at one end of the support frame, and a conveying mechanism at the other end for conveying printed materials to be packaged into the packaging mechanism. A limiting mechanism is provided above the packaging mechanism, and there are two limiting mechanisms. A driving mechanism is provided on the support frame below the packaging mechanism.

[0006] The limiting mechanism comprises a limiting plate, the limiting plate is fixedly connected with the moving end of the driving mechanism, a fixing frame is fixed on the top of the limiting plate, an L-shaped plate is slidably fitted on the fixing frame, a unidirectional screw is threadedly fitted on the top of the fixing frame, the bottom of the unidirectional screw passes through the top of the fixing frame and is rotatably connected to the top of the L-shaped plate, and a plurality of pressing rollers are rotatably arranged at the bottom of the L-shaped plate along the length direction of the L-shaped plate.

[0007] As a preferred solution of the present utility model, the fixing frame comprises a fixing plate, fixing rods are fixed at both ends of the bottom of the fixing plate, the bottom of the fixing rods is fixed on the top of the limiting plate, a screw hole adapted to the unidirectional screw is penetratingly opened on the fixing plate, round holes are penetratingly opened at both ends of the transverse plate of the L-shaped plate, and the round holes are slidably fitted with the fixing rods.

[0008] Through the above technical solution, the sliding fit between the round holes and the fixing rods provides guidance for the L-shaped plate, restricting the L-shaped plate to only move up and down along the axial direction of the fixing rods, preventing the L-shaped plate from shifting left and right when adjusting the unidirectional screw, and ensuring that the pressing rollers are always aligned with the upper area of the printed matter.

[0009] The polishing treatment on the inner wall of the round hole reduces sliding friction with the fixing rod, making it more labor-saving for operators to rotate the unidirectional screw to adjust the height of the pressing roller, avoiding jamming after long-term use, and improving operational convenience.

[0010] As a preferred solution of the present utility model, the driving mechanism comprises a base fixed on the support frame, a bidirectional screw is rotatably arranged on one side of the inner surface of the base, a rotating rod is fixed at the other end of the bidirectional screw, one end of the rotating rod passes through the side wall of the base, two screw barrels with opposite movement directions are threadedly fitted on the bidirectional screw, two guide rods are fixed on the inner surfaces of the two side plates of the base and respectively located on both sides of the bidirectional screw, guide barrels are slidably fitted on the guide rods, connecting rods are fixed at both ends of the outer wall of the screw barrel, the other end of the connecting rods is fixed on the corresponding guide barrels, supporting rods are fixed on the guide barrels, and two supporting rods located on the same side respectively pass through the conveying mechanism and are fixed on the bottom of the limiting plate.

[0011] Through the above technical solution, synchronous adjustment of the spacing between the two limiting mechanisms can be realized.

[0012] As a preferred solution of the present utility model, the base is in a U-shape, a through hole is penetratingly opened on one side of the base, the rotating rod is in clearance fit with the through hole, and a rotating handle is fixed at the end passing through the through hole.

[0013] Through the above technical solution, the U-shaped base provides an open installation space for components such as the bidirectional screw and the screw barrels, components can be directly disassembled from the top or side during later maintenance without disassembling the entire base, which reduces maintenance difficulty.

[0014] The rotating handle (with anti-slip grooves) increases the operator's grip area, requiring less effort than directly rotating the lever and reducing hand fatigue. The clearance fit between the through hole and the rotating lever ensures smooth rotation of the lever while preventing wobbling that could reduce adjustment accuracy.

[0015] As a preferred embodiment of this utility model, the two threaded cylinders are provided with threaded holes in opposite directions, and the guide cylinder is provided with a guide hole.

[0016] Through the above technical solution, the reverse threaded holes of the two threaded cylinders are matched with the left and right threads of the bidirectional screw, ensuring that when the bidirectional screw is rotated, the two threaded cylinders can move synchronously in the "closer" or "farther" direction, thereby driving the limit plates on both sides to adjust the distance synchronously, avoiding the offset of printed materials caused by unilateral adjustment and improving the limit accuracy.

[0017] The guide hole of the guide cylinder cooperates with the guide rod, restricting the threaded cylinder to move only in a straight line along the guide rod, eliminating the problem of the threaded cylinder rotating synchronously with the bidirectional screw, and ensuring the stability of the limit plate spacing adjustment.

[0018] As a preferred embodiment of this utility model, the pressure roller includes mounting plates fixed on both sides of the bottom of the L-shaped plate, and a roller body is rotatably connected between the two mounting plates.

[0019] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the structural design of a limiting plate, a fixing frame, an L-shaped plate, a one-way screw, and a pressure roller, allows the operator to adjust the height of the L-shaped plate according to the height of the printed materials to be packaged. This enables the L-shaped plate to meet the limiting requirements of printed materials of different heights, while also preventing the upper printed materials from falling off due to excessive limiting pressure.

[0020] 2. This utility model has a rotatable pressure roller at the bottom of the L-shaped plate. When the L-shaped plate limits the top of the printed material, it can play a rolling guiding role. Compared with the existing technology, the rolling contact method not only ensures the limiting requirement, but also reduces the wear on the printed material.

[0021] 3. Through the structural design of the base, bidirectional screw, threaded cylinder, guide rod and guide tube, this utility model allows for adjustment of the distance between the two limiting mechanisms according to usage requirements when using this device. This makes it suitable for packaging needs of printed materials of different sizes. It can solve the problem in the prior art that when the width of the printed material is between the distances corresponding to the two slots, it cannot be fully fitted, which can easily lead to the offset of the printed material during the packing process and affect the subsequent packing neatness.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0027] For examples, please refer to Figure 1-6 This utility model provides a technical solution: A printing and packaging device includes a support frame 1, a packaging mechanism 2 is provided at one end of the support frame 1, and a conveying mechanism 3 is provided at the other end to convey the printed matter to be packaged into the packaging mechanism 2. A limiting mechanism 4 is provided above the packaging mechanism 2, and there are two limiting mechanisms 4. A driving mechanism 5 is provided on the support frame 1 below the packaging mechanism 2.

[0028] The drive mechanism 5 is the same as the existing structure for conveying printed materials. It is a roller conveyor, which is arranged along the length of the support frame 1. The roller spacing is 5 to 8 cm, which allows the support rod 56 to pass through and be fixed to the limiting plate 40. The roller material is polyurethane (hardness 60 Shore A, to avoid scratching the surface of the printed materials). Dustproof bearings are provided at both ends of the roller to reduce wear during long-term use and adapt to the needs of continuous batch packaging.

[0029] The packaging mechanism 2 has the same structure as the existing technology, and its packaging process and principle are the same as the existing technology, so it will not be described in detail here.

[0030] The limiting mechanism 4 includes a limiting plate 40, which is fixedly connected to the moving end of the driving mechanism 5. A fixing frame 41 is fixed on the top of the limiting plate 40. An L-shaped plate 42 is slidably fitted on the fixing frame 41. A one-way screw 43 is threadedly fitted on the top of the fixing frame 41. The bottom of the one-way screw 43 passes through the top of the fixing frame 41 and is rotatably connected to the top of the L-shaped plate 42. Several pressure rollers 44 rotate along the length of the L-shaped plate 42 at the bottom of the L-shaped plate 42.

[0031] In this embodiment, the fixing frame 41 includes a fixing plate, and fixing rods are fixed at both ends of the bottom of the fixing plate. The bottom of the fixing rods is fixed to the top of the limiting plate 40. A screw hole adapted to the one-way screw 43 is opened through the fixing plate. A round hole is opened through both ends of the horizontal plate of the L-shaped plate 42. The round hole slides with the fixing rod.

[0032] The top of the one-way screw 43 is equipped with a rubber anti-slip knob with a knurled surface, and the bottom is rotatably connected to the horizontal plate of the L-shaped plate 42 through a deep groove ball bearing to prevent the L-shaped plate 42 from rotating synchronously when the screw 43 rotates.

[0033] Through the above technical solution, the sliding fit between the round hole and the fixed rod provides guidance for the L-shaped plate 42, restricting the L-shaped plate 42 to move only up and down along the axis of the fixed rod, avoiding the L-shaped plate 42 from shifting left and right when adjusting the one-way screw 43, and ensuring that the pressure roller 44 is always aligned with the upper area of ​​the printed matter.

[0034] The polishing treatment of the inner wall of the round hole reduces the sliding friction with the fixed rod, making it easier for the operator to adjust the height of the pressure roller 44 by turning the one-way screw 43. It is also less likely to jam after long-term use, thus improving the ease of operation.

[0035] In this embodiment, the drive mechanism 5 includes a base 50 fixed on the support frame 1. A bidirectional screw 51 is rotatably mounted on one side of the inner surface of the base 50. A rotating rod is fixed to the other end of the bidirectional screw 51. One end of the rotating rod passes through the side wall of the base 50. Two threaded cylinders 52 with opposite directions of movement are threaded onto the bidirectional screw 51. Two guide rods 53 are fixed to the inner surfaces of the two side plates of the base 50, respectively located on both sides of the bidirectional screw 51. A guide cylinder 54 slides on the guide rod 53. Connecting rods 55 are fixed to both ends of the outer wall of the threaded cylinder 52. The other end of the connecting rod 55 is fixed to the corresponding guide cylinder 54. A support rod 56 is fixed to the guide cylinder 54. The two support rods 56 located on the same side pass through the conveying mechanism 3 and are fixed to the bottom of the limiting plate 40.

[0036] The above technical solution can achieve synchronous adjustment of the distance between the two limiting mechanisms 4.

[0037] In this embodiment, the base 50 is shaped like a "U". A through hole is provided on one side of the base 50. The rotating rod is fitted with the through hole with a clearance, and a rotating handle is fixed at one end of the rod that passes through the through hole.

[0038] Through the above technical solution, the "U"-shaped base 50 provides an open installation space for components such as the bidirectional screw 51 and the threaded cylinder 52. During later maintenance, the components can be directly disassembled from the top or side without disassembling the entire base, thus reducing the difficulty of maintenance.

[0039] The rotating handle (with anti-slip grooves) increases the operator's grip area, requiring less effort than directly rotating the lever and reducing hand fatigue. The clearance fit between the through hole and the rotating lever ensures smooth rotation of the lever while preventing wobbling that could reduce adjustment accuracy.

[0040] In this embodiment, the two threaded cylinders 52 have threaded holes with opposite thread directions, and the guide cylinder 54 has a guide hole.

[0041] Through the above technical solution, the reverse threaded holes of the two threaded cylinders 52 are matched with the left and right threads of the bidirectional screw 51, ensuring that when the bidirectional screw 51 is rotated, the two threaded cylinders 52 can move synchronously in the "closer" or "farther" direction, thereby driving the two side limit plates 40 to adjust the spacing synchronously, avoiding the offset of printed materials caused by unilateral adjustment and improving the limit accuracy.

[0042] The guide hole of the guide cylinder 54 cooperates with the guide rod 53 to restrict the threaded cylinder 52 to move only in a straight line along the guide rod 53, thus preventing the threaded cylinder 52 from rotating synchronously with the bidirectional screw 51 and ensuring the stability of the spacing adjustment of the limit plate 40.

[0043] In this embodiment, the pressure roller 44 includes mounting plates fixed to both sides of the bottom of the L-shaped plate 42, and a roller body is rotatably connected between the two mounting plates.

[0044] The roller body is made of silicone (hardness 60-70 Shore A, anti-indentation and anti-slip), and its length is the same as that of the limiting plate 40. The mounting plate is fixed to the bottom of the vertical plate of the L-shaped plate 42 by bolts. Both ends of the roller body are rotatably connected to the mounting plate through bearings to ensure that the pressure roller 44 can roll synchronously when the printed matter is conveyed without obstructing the conveying.

[0045] The workflow of this utility model: The printing and packaging device for printed materials designed using this solution operates as follows: The operator holds the rotating handle of the drive mechanism 5. Rotating the handle drives the bidirectional screw 51 to rotate synchronously. The left and right threads of the bidirectional screw 51 drive the two threaded cylinders 52 to move synchronously in opposite directions along the guide rod 53 (moving closer when rotating clockwise and moving further away when rotating counterclockwise). The threaded cylinders drive the guide cylinder 54 to move synchronously through the connecting rod 55. The guide cylinder 54 then drives the two side limiting plates 40 to move closer / away through the support rod 56 until the inner side of the limiting plate 40 matches the width of the printed material (gap 0.5~1cm, to avoid excessive tightness or excessive looseness).

[0046] For printed materials of different thicknesses, the operator rotates the top knob of the one-way screw 43 of the limiting mechanism 4. The one-way screw 43 rotates axially along the screw hole of the fixed plate, and the bottom drives the L-shaped plate 42 to slide up and down along the fixed rod through the bearing (the L-shaped plate descends when rotated clockwise and rises when rotated counterclockwise).

[0047] Observe the distance between the pressure roller 44 and the conveyor mechanism 3 until the pressure roller gently touches the upper surface of the printed matter (pressure 5-10N, which can prevent the paper from falling off without damaging the printed matter). The adjustment is complete.

[0048] Start the conveyor mechanism 3 and place the printed materials to be packaged (such as stacked brochures) at the feed end of the conveyor mechanism 3. The printed materials move towards the packaging mechanism 2 with the roller conveyor. The side limit plates 40 restrict the left and right deviation of the printed materials to avoid side skewing. The upper pressure roller 44 rolls synchronously with the printed materials to apply uniform pressure to the upper surface of the printed materials to prevent the upper paper from curling up and falling. The printed materials enter the feed port of the packaging mechanism 2 through the conveyor mechanism 3 and are guided to move to the packaging position for packaging.

[0049] The conveying mechanism 3 used in this utility model is a roller conveyor, and the structure of the packaging mechanism 2 is the same as that of the comparative patent. Both are existing known electrical devices and can be directly purchased and used on the market. Their structure, circuit and control principle are existing known technologies. Therefore, the structure, circuit and control principle of the conveying mechanism 3 and the packaging mechanism 2 will not be described in detail here.

[0050] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
