Description

Horizontal die-cutting indentation and hot-stamping machine for vacuum paper conveying

Technical Field

The utility model relates to a packaging machinery, especially a horizontal concora crush flat die cutting indentator and thermoprinting machine that is used for printing packing later process processing corrugated container board.

Background

The horizontal flat-pressing flat-die cutting and marking machine and the hot stamping machine have the same attribute (hereinafter referred to as a die-cutting machine) which can be used mutually, and products sold in the market at present are divided into two types, namely a gripper type (traditional type) and a non-gripper type according to the structure. The defects of the gripper card type are as follows: the structure is very complicated, the cost is high, the failure rate is high, the debugging is difficult, and the maintenance is difficult. The defect of the gripper-free card type is that: the mode that paper is pushed to the top of paper or is impacted by the paper is adopted for paper feeding, so that the paper feeding device is not suitable for processing thin paper, double paper is easy to appear, waste products are caused, and the market sale is limited. The market of the die cutting machine still takes the traditional type with a gripper plate as a main part at present. In the field of die cutting machines, under the condition of sufficient pressure, the problems mainly needed to be solved are paper feeding and positioning, and the failure rate of the paper feeding and positioning is more than 95 percent: the defects are caused by the adoption of a huge chain system and a gripper plate structure in the traditional paper feeding process; the gripper-plate-free type has simple structure because no gripper plate has no huge chain transmission system, and the mode of paper ejection or paper impact on paper is adopted for paper feeding, such as: patent number 99101547.9 description in the specification of gripper-free automatic quick paper feeding system: "the second sheet starts running and advances against the first sheet pressed in front of it, … …" (taken from page 4, lines 4-5 of the specification); the specification '200710181993.7 die-cutting and impressing (hot stamping) machine for front edge paper clamping and disposable paper top' describes that 'another original paper board is conveyed by a conveying device, the front end of the original paper board is propped against the rear end of the static die-cut paper board in front of the original paper board, and the original paper board and the static die-cut paper board advance together, … …' (0013, lines 1-3); patent number 201010124552.5 description in the specification of "a horizontal platen die cutting and creasing and stamping machine": "paper feeding mode … … (0006 segment 2-3 lines from the last) of impacting the paperboard with the paperboard". This also actually pertains to the top paper, but the accelerated board is used to top the previous one. The common feature of the above patents is that the cardboard is a top cardboard, and the defects are that the processed tissue is easy to be empty, double sheets appear, and waste products are caused. Patent No. 201310518680.1 of oblique and horizontal flat-pressing die-cutting machine with waste removing function for flying paper feeding is also disclosed, although oblique and horizontal die-cutting machines are not comparable, because the patent of die-cutting machine is also analyzed, the paper feeding mode description describes the following: the flying paper feeding process is as follows: when the movable die-cutting pallet is opened at a certain angle, a paper is delivered from the paper feeding nozzle, the air source of the paper feeding nozzle is cut off by the air source control device, the paper freely falls onto the longitudinal positioning gauge which is already at the advanced position, the lateral positioning gauge advances at the moment, after the paper is longitudinally and laterally positioned, the two die-cutting pallets are pressed together, the paper is die-cut, (see lines 7-10 of 0005) … … the longitudinal positioning assembly of the machine mainly comprises: the device comprises a longitudinal positioning gauge, a cylinder seat, a double-shaft cylinder, a tension spring and a slide rail; … … (see line 0006, line 1); because the paper is fed in a free falling body mode, the positioning of the paper board is difficult, the positioning gauge is complex in structure and difficult to position accurately, the working speed is seriously influenced by the positioning, the speed is improved, the inaccurate positioning is easy to occur, and the rejection rate is high. So this model has not been able to reach the market to date. The positioning of various types of paper boards adopts mechanical positioning rule positioning, and the common defect is that the mechanical structure is complex and a whole set of driving system is required to complete the positioning. It is generally difficult to adjust and maintain the positioning accuracy during operation, which results in high rejection rate and failure rate, including the traditional products that are currently mainly on the market. Positioning as used herein refers to longitudinal positioning and, hereinafter, lateral positioning, as lateral positioning provides greater positioning accuracy with conventional commercially available paper feeding systems.
