Description

Technical Field

[0001] The present invention relates to the technical field of production of sheet materials such as flat printed matter, packaging bags, and paper, and in particular to a branch transmission device for sheet materials. Background Art

[0002] After flat printed materials, packaging bags, paper and other sheet materials are produced, they need to go through processes such as stacking, sorting, packaging and bundling before the production process is completed and they can be shipped out of the factory at any time.

[0003] Automated and mechanized stacking, sorting, packaging, and bundling of sheet materials requires conveying these materials. During sheet conveying, diverter plates are typically installed on both sides to guide and limit the material, ensuring that the sheet material is neatly and linearly transported. However, due to the thinness, softness, and light weight of individual sheets, wrinkles easily form during conveyance, and the low friction between the sheets and the conveying surface can also cause slippage and accumulation.

[0004] The patent application with application number CN201810591627.7 discloses a high-speed intelligent identification and bag sorting machine. The application involves a pressure wheel module, which is arranged above the feed conveying module. The pressure wheel module uses multiple sets of pressure wheels to press the middle of the plastic bag passing through each conveying channel in the feed conveying module downward.

[0005] While the aforementioned pinch roller module compression method can address wrinkle and slippage issues during sheet material conveying, in actual production, sheet material sizes frequently change, and the position and distance between the branch baffles may change. Consequently, the pinch roller module must be frequently adjusted to ensure it is positioned within the transmission path between the branch baffles. This results in numerous, time-consuming, and laborious adjustments to the entire device. Summary of the Invention

[0006] The purpose of the present invention is to provide a branch transmission device for sheet materials, which can solve the problems of wrinkles and slippage in the sheet material transportation process, and there is no need to adjust the position of the pressure wheel assembly when switching the size of the sheet material, saving time and effort.

[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0008] The present invention discloses a branch transmission device for sheet materials, which includes a transmission mechanism and a branch baffle. The branch baffle is vertically arranged above the transmission mechanism and is parallel to the transmission direction of the transmission mechanism. The branch baffles are relatively arranged to separate branch transmission channels. A pressure wheel assembly is installed on the branch baffle.

The pressure wheel is installed on the branch baffle through a pressure wheel mounting frame. The pressure wheel belt passes around the pressure wheel.

[0015] As a preferred technical solution, the installation position of the pressing wheel can be moved up and down.

[0016] As a preferred technical solution, pressure wheel assemblies are installed on the branch baffles on both sides of the branch transmission channel.

[0019] As a preferred technical solution, the branch baffle is driven by a baffle reciprocating motion mechanism to move relative to the branch baffle mounting beam.

[0020] As a preferred technical solution, the baffle reciprocating motion mechanism is a gear rack transmission mechanism, a nut screw mechanism, a cylinder, a hydraulic cylinder, an electric cylinder or a linear motor.

[0021] As a preferred technical solution, the transmission mechanism is a belt conveyor, which includes a transmission roller and several conveyor belts. The conveyor belts pass around the transmission rollers and are arranged in parallel and at intervals. The bottom of the branch baffle extends from the gap between the conveyor belts into below the transmission surface of the conveyor belts.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described below with reference to the accompanying drawings.

[0030] The sheet material described in the present invention can be sheet materials in various forms such as flat printed matter, packaging bags, paper, etc., all of which are applicable to the present invention.

[0031] The automatic adjustment and automatic distance adjustment described in the present invention means that the movement of the branch baffle is driven by electric drive, pneumatic drive, hydraulic drive, etc., without the need for an operator to manually drive the movement of the branch baffle. Manual adjustment may require opening the outer casing and may be affected by the installation location and other mechanisms, making it inconvenient to operate. Moreover, reaching into the machine to make adjustments may pose a safety hazard. Automatic adjustment, on the other hand, does not require opening the outer casing and is not affected by the installation location and other mechanisms. Adjustments can be made externally without reaching into the machine, ensuring safety. In addition, the method for controlling the movement of the baffle reciprocating motion mechanism can be manual control or control by a control system.

[0032] Example 1

[0033] The branch transmission device of embodiment 1 is as follows Figures 1 to 4 As shown, the shunt transmission device includes a transmission mechanism 1 and a shunt baffle 2. The shunt baffle 2 is vertically arranged above the transmission mechanism 1 and is parallel to the transmission direction of the transmission mechanism 1. The shunt baffles 2 are relatively arranged to separate a shunt transmission channel. A pressure wheel assembly 3 is installed on the shunt baffle 2. The pressure wheel assembly 3 is located in the shunt transmission channel and is used to press the sheet material toward the transmission surface of the transmission mechanism 1. When the sheet material is conveyed to the pressure wheel assembly 3, it is pressed and flattened by the pressure wheel assembly 3, which plays a role in auxiliary conveying and solves the problems of wrinkles and slippage in the sheet material conveying process. When the position of the shunt baffle 2 is adjusted, the pressure wheel assembly 3 can be adjusted accordingly. Therefore, when switching the size of the sheet material, there is no need to adjust the position of the pressure wheel assembly, which saves time and effort.

[0034] As one of the structural forms of the pressure roller assembly 3, in this embodiment, the pressure roller assembly 3 includes a roller 4 and a roller mounting frame 5, and the roller 4 is installed on the branch baffle 2 through the roller mounting frame 5, and the roller 4 is close to or contacts the transmission surface of the transmission mechanism 1.

[0035] As one structural form of the roller 4, in this embodiment, the roller 4 is a cylindrical roller, which is arranged horizontally and the axial direction of the roller 4 is perpendicular to the transmission direction of the transmission mechanism 1. The horizontal cylindrical roller increases the coverage of the roller on the branch transmission channel, making the roller's compaction and flattening effect more obvious.

[0036] Multiple rollers can be provided, or only one or two can be provided, for example, one at the feed end of the conveyor mechanism and one at the discharge end. Preferably, at least two rollers 4 are provided within each branch transmission channel, and the rollers 4 are cross-mounted on the branch baffles 2 on either side of the branch transmission channel along the transmission direction of the conveyor mechanism. Cross-mounting the rollers 4 on either side of the branch transmission channel ensures that, regardless of the width of the branch transmission channel, the rollers 4 consistently cover both ends of the sheet material, providing a uniform and stable effect on the sheet material.

[0037] In this embodiment, the installation position of the roller 4 can be moved up and down, so as to facilitate adjustment of the distance between the roller 4 and the conveying surface or the distance between the roller 4 and the conveying surface, and adapt to sheet materials of various thicknesses, softnesses and hardnesses.

[0038] As one of the ways to move the installation position of the roller 4 up and down, the roller mounting frame 5 is provided with a longitudinal strip mounting hole 6, and the roller mounting frame 5 is connected to the branch baffle 2 through the longitudinal strip mounting hole 6.

[0039] The branch baffle 2 can move perpendicularly to the transmission direction of the transmission mechanism 1. When the size of the sheet material is switched, the branch baffle 2 is moved to adjust the width of the branch transmission channel.

[0040] As one of the ways to move the branch baffle 2, the branch transmission device also includes a branch baffle mounting beam 7 that spans above the transmission mechanism 1 and is perpendicular to the transmission direction of the transmission mechanism 1. The branch baffle 2 is movably mounted on the branch baffle mounting beam 7 along the axial direction of the branch baffle mounting beam 7.

[0041] The movement of the branch baffle 2 on the branch baffle mounting beam 7 can be adjusted manually or automatically. For example, the branch baffle 2 is driven by the baffle reciprocating motion mechanism 8 to move relative to the branch baffle mounting beam 7. The baffle reciprocating motion mechanism 8 can be various conventional reciprocating motion mechanisms such as a gear rack transmission mechanism, a nut screw mechanism, a cylinder, a hydraulic cylinder, an electric cylinder, a linear motor, etc., as long as it can drive the branch baffle 2 to perform reciprocating motion to adjust its position. For example: In this embodiment, the baffle reciprocating motion mechanism 8 is a gear rack transmission mechanism, the rack of the gear rack transmission mechanism is installed on the branch baffle mounting beam 7, and the gear and the drive motor are installed on the branch baffle 2.

[0042] In this embodiment, the transmission mechanism 1 is a belt conveyor, which includes a transmission roller 9 and a plurality of conveyor belts 10. The conveyor belts 10 pass around the transmission roller 9 and are arranged in parallel and spaced apart. The bottom of the branch baffle 2 extends from the gap between the conveyor belts 10 into the transmission surface below the conveyor belt 10, as shown in FIG. Figure 3 The branch baffle is extended below the transmission surface, so that it does not interfere with the transmission of the transmission mechanism, and no gap is left between the bottom of the branch baffle and the transmission surface, thus solving the problem of deviation and leakage of sheet materials during the transportation process.

[0043] Example 2

[0044] The difference between Example 2 and Example 1 lies in the different structural form of the pressure roller assembly: in Example 2, the pressure roller assembly includes a pressure roller and a pressure roller belt. The pressure roller is mounted on the diversion baffle via a pressure roller mounting bracket. The pressure roller belt passes around the pressure roller, is parallel to the transmission direction of the transmission mechanism, and is close to or in contact with the transmission surface of the transmission mechanism. The pressure roller assembly consisting of the pressure roller and the pressure roller belt, when mounted on the diversion baffle, can also achieve the objectives of the present invention.

[0045] The pressure wheel mounting frame can adopt a structure and installation method similar to that of embodiment 1, and the installation position of the pressure wheel can be moved up and down.

[0046] The branch baffles on both sides of the branch transmission channel are equipped with pressure wheel assemblies, so that the pressure wheel assemblies can always cover both ends of the sheet material and have a uniform and stable effect on the sheet material.

[0047] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
