Description

Extruding two of compounding machine unreels the automatic change of lap of pre-speed mechanism at a high speed

One, technical field

The utility model relates to and a kind ofly is applied to paper, plastic-aluminum, moulds with compound high speeds of plastic flexible packaging material such as paper plastic-aluminums and extrude compounding machine, specifically relates to two unreeling structures that this extrudes compounding machine at a high speed.

Two, background technology

Existing high speed is extruded compounding machine and is comprised first unreeling structure (also claiming main unreeling structure) and second unreeling structure (also claiming secondary unreeling structure), wherein second unreeling structure is called for short two unreeling structures, because its space is limited, the design improvement difficulty is big, generally adopts the film change of lap mode that manually connects.This manually connects the film mode because the not pre-speed of new volume is rotated, and armrest promotes, and speed is lower, causes disconnected film easily, and it is low to connect the film success ratio.And troublesome poeration, influenced production efficiency.

Three, utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and provides a kind of high speed that can realize that new volume quickens to rotate, do not shut down automatic change of lap in advance to extrude two unreeling structures of compounding machine.

The purpose of this utility model realizes by following technical solution: a kind of high speed is extruded two of compounding machine and is unreeled the automatic change of lap of pre-speed mechanism, comprise that swivel arm, rotating shaft, gas expansion shaft, two unreel wallboard, deflector roll support, upset deflector roll and the rotating shaft of upset deflector roll, transition deflector roll and the rotating shaft of transition deflector roll, drg is housed in the swivel arm, in swivel arm, be provided with power-transfer clutch and drg links, power-transfer clutch by chain wheel set be contained in the two pre-speed motors of master that unreel on the wallboard and link; Cutting knife cylinder and tailing axle are housed on the deflector roll support, in the rotating shaft of upset deflector roll, knife rest swing arm, knife rest and cutting knife are housed; In the rotating shaft of transition deflector roll, swing arm is housed, the pressure roller cylinder is housed in the swing arm, the other end of swing arm is equipped with pressure roller and plain bearing housing, pressure roller links with press roll gear again, press roll gear and motor gear link, motor gear links by transition axis and spacer shell and the secondary pre-speed motor that is contained in this combined wall board side of extruding compounding machine, and in the two vertical vertex of side, the pressure roller positions that unreel wallboard photocell eye is housed.

After adopting the utility model structure, the basement membrane of current volume is when having sent, swivel arm rotates and makes new volume forward nadir to, main pre-speed motor starts and the drive gas expansion shaft rotates and make new volume obtain in advance quickening to rotate, secondary pre-speed motor startup and drive pressure roller and swing arm rotate to the upright position, then pressure roller is upwards pressed to new volume and on the basement membrane rolled up before adhesive tape on the new volume is adhered to through the pressure roller cylinder, and the basement membrane of preceding volume is cut off by cutting knife.So far, new volume and preceding volume are finished the change of lap action automatically.Therefore, the utility model compared with prior art, connecing film and finishing automatically of new volume and preceding volume realized not shutting down the automatic change of lap that do not slow down, production efficiency is improved.

Four, description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Five, the specific embodiment

Referring to figs. 1 through Fig. 4 as can be known, the utility model is extruded two of compounding machine at a high speed and is unreeled the automatic change of lap of pre-speed mechanism, comprise that swivel arm 27, rotating shaft 26, gas expansion shaft 25, two unreel wallboard 20, deflector roll support 12, upset deflector roll 19 and 15 (as shown in Figure 1) of upset deflector roll rotating shaft, transition deflector roll 11 and transition deflector roll rotating shaft 10 (as shown in Figure 2), drg 24 is housed in the swivel arm 27, in swivel arm 27, be provided with power-transfer clutch 23 and link with drg 24, power-transfer clutch 23 by chain wheel set 22 be contained in the two pre-speed motors 21 of master that unreel on the wallboard 20 and link (as shown in Figure 4); Cutting knife cylinder 14 and tailing axle 13 are housed on deflector roll support 12, in upset deflector roll rotating shaft 15, knife rest swing arm 16, knife rest 17 and cutting knife 18 (as shown in Figure 1) are housed; In transition deflector roll rotating shaft 10, swing arm 8 is housed, pressure roller cylinder 9 is housed in the swing arm 8, the other end of swing arm 8 is equipped with pressure roller 7 and plain bearing housing 6, pressure roller 7 links with press roll gear 5 again, press roll gear 5 links with motor gear 4, motor gear 4 links (as shown in Figure 2) with the secondary pre-speed motor 1 that is contained in these combined wall board of extruding compounding machine 31 sides by transition axis 3 and spacer shell 2, and in two side, the pressure roller 7 vertical vertex positions that unreel wallboard 20 photocell eye 28 (as shown in Figure 1) is housed.Component set-up turning racks such as above-mentioned rotating shaft 26, gas expansion shaft 25, swivel arm 27, chain wheel set 22, power-transfer clutch 23, drg 24.

Workflow of the present utility model is: the basement membrane of the preceding volume 30 on gas expansion shaft prepares to renew volume 29 o'clock near having sent, and turning rack rotates, and when new volume nadir arrived the photocell eye position and covers photocell eye, turning rack stopped operating (as shown in Figure 1); Then main pre-speed motor starts, and makes the gas expansion shaft in the new volume of clutch engagement of new volume side by chain wheel set and drg is thrown off, and rotates and makes new volume quicken in advance to rotate (as shown in Figure 4) thereby drive gas expansion shaft; Start secondary pre-speed motor, drive motor gear, press roll gear successively by transition axis and make the pressure roller rotation, pressure roller and swing arm rotate to upright position (press roll gear disengagement then, pressure roller is rotated further by its inertia), the pressure roller cylinder advances and pressure roller is upwards pressed to new volume subsequently, before adhesive tape on the new volume is adhered on the basement membrane of volume, then the cutting knife cylinder advances and the basement membrane of preceding volume is cut off (as shown in Figure 1 and Figure 2) with cutting knife.At this moment, close main pre-speed motor, newly roll up the brake engages of side and throw-out-of clutch, gas expansion shaft stops the rotation, and pressure roller and swing arm rotate to level attitude.So far, new volume on two unreeling structures and preceding volume are finished the change of lap action automatically.So the utility model can make the new volume on two unreeling structures and the film that connects of preceding volume finish automatically, has realized not shutting down the automatic change of lap that do not slow down.
