Horizontal flat pressing flat die-cutting creasing and thermoprinting machine

Abstract

The invention discloses a horizontal flat pressing flat die-cutting creasing and thermoprinting machine. The machine is provided with an upper impressing pallet, a lower impressing pallet and a paper feeding mechanism, wherein the upper impressing pallet is provided with an eccentric shaft device, an upper wedge for the pressure adjustment of the lower pallet and a lower wedge for the pressure adjustment of the lower pallet are arranged below the lower impressing pallet, the upper impressing pallet is a hollow shell, the upper wedge for the pressure adjustment of the upper pallet and the lower wedge for the pressure adjustment of the upper pallet are laterally arranged in the hollow cavity, the left side wall and the right side wall of the hollow shell are respectively provided with a pressure adjustment jackscrew, the pressure adjustment jackscrews on the left side wall and the right side wall are positioned in the corresponding positions at the left end surface and the right end surface of the upper wedge for the pressure adjustment of the upper pallet, and a plurality of rib plates are fixed on the top surface of the hollow cavity. The horizontal flat pressing flat die-cutting creasing and thermoprinting machine has the advantages that both the upper pallet and the lower pallet can adjust the die-cutting pressure, and the phenomenon of failure to jack up the paper board is avoided.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a horizontal flat die-cutting creasing and hot stamping machine used for processing corrugated cardboard in the subsequent process of printing and packaging. Background technique [0002] The horizontal flat die-cutting creasing machine and the hot stamping machine have the same attributes that can be used interchangeably (hereinafter referred to as the die-cutting machine). Among the products currently on the market, they are divided into types with grippers (traditional type) according to their structure. And the jawless type, the structure of the non-grip type is simple, accurate, low-cost, and the development prospect is promising, but there are still fatal shortcomings in the new product of the no-grip type. Therefore, it has not really been sold in the market. The working principle is: 1. The die-cutting is completed by pressing the upper and lower pallets together. The upper pallet m...

Problems solved by technology

The disadvantage is that the longitudinal (that is, local) pressure cannot be adjusted. This is not its fatal shortcoming, but a common problem in the products of horizontal flat die-cutting machines. Pad paper on the back of the plate to compensate for the pressure, the operation is troublesome and time-consuming

2. The paper feeding method adopts the method of "cardboard top cardboard" without grippers, as described in the patent No. 99101547.9 "Automatic Rapid Paper Renewal System Without Grippers": "The second paper starts to run, and Go forward with the embossed first sheet of paper in front of it,..." (excerpted from the 4th-5th line on page 4 of the specification); "Die-cutting and creasing (hot stamping) machine for permanent paper top paper" describes that "another original cardboard is conveyed by the conveying device, and its front end pushes against the rear end of the static die-cut cardboard in front of it. , and move forward together,..." (line 16-18 on page 5) The disadvantage of the above two schemes is: "the cardboard tops the cardboard and moves forward together", obviously the previous cardboard is replaced by the back one If the cardboard travels against the cardboard, the paper feeding speed will not be high. For flat cardboard and the speed is not high, "cardboard top cardboard will go forward together". When the jitter is aggravated, it is inevitable that the cardboard headspace phenomenon will occur, and it cannot "go forward together", causing double or multiple overlaps in the machine, resulting in waste products.

3. The positioning adopts push-to-set positioning, and the patent application number is 200710181993.7 "Front edge paper positioning and disposable paper top paper die-cutting creasing (hot stamping) machine" describes in the manual that "this machine only uses two pushing paper Positioning gauge, the positioning gauge is composed of main clamp body, lower clamp body, guide post, upper compression spring, piston, piston body, side compression spring, bottom compression spring, threaded guide column, roller, pin shaft, swing rod and torsion spring; "(The 12th-13th line of the 5th page) also has: "A weight iron 5 is installed on the platen on the embossing, ... clamping the inclined iron 21, ..... The positioning gauge driving device 19 is mainly It is composed of positioning gauge seat 16, bearing 17..." (page 7, line 1-5) The disadvantage is: the structure of the positioning gauge is too complicated, there are many parts, and there are many actions to be performed. Once the speed increases, the movement is difficult , there will be movement failure and failure

[0003] The above-mentioned deficiencies are the main reasons why this product has not been able to form a real market sale so far.
