Description

Drawing mechanism

Technical field

This utility model relates to napkin folder field, particularly to the drawing mechanism of medicated napkin.

Background technology

The drawing mechanism of existing napkin folder generally uses two pinch rolls abutted to rotate Conveying medicated napkin, medicated napkin is between two pinch rolls during paper delivery, by the shift fork on respective pinch roll Alternately releasing and folded by medicated napkin, owing to shift fork length is shorter, when shift fork is released, medicated napkin easily presss from both sides The gap entering shift fork and pinch folded roller, causes the fault of paperboard, have impact on the folding efficiency of medicated napkin.

Utility model content

The purpose of this utility model is to provide for a kind of drawing mechanism, it is to avoid when medicated napkin paper delivery folds Produce the fault of paperboard.

According to an aspect of the present utility model, it is provided that drawing mechanism, including frame, two pinch rolls, Shift fork, rotating mechanism and swing mechanism, the outer rim of two pinch rolls is installed on frame with abutting, and two Pinch roll is connected to the rotating mechanism driving pinch roll to rotate, and rotating mechanism is connected to shift fork The swing mechanism swung, shift fork is installed on swing mechanism along the outer rim of two pinch rolls respectively, the end of shift fork End be positioned at two pinch rolls against place or stretch out two pinch rolls against place.

Due to the end of shift fork be positioned at two pinch rolls against place or stretch out two pinch rolls against place, dial The end of fork is very close to each other with against place, and shift fork length is along the outer rim of pinch roll, when medicated napkin sends into two Time between pinch roll, the medicated napkin outer rim paper delivery from pinch roll can be always ensured that, it is to avoid medicated napkin Sandwich the gap of shift fork and pinch roll, cause the fault of paperboard.

In some embodiments, frame includes two gripper shoes and four support columns, and two gripper shoes pass through four The individual parallel installation of support column being perpendicular to gripper shoe, rotating mechanism includes motor, two main shafts, the first axle Hold and bearing block, two main shafts respectively sheathed pinch rolls, each main shaft two ends be provided with clutch shaft bearing and Bearing block, bearing block is individually fixed in two gripper shoes, and motor power connects one end of two main shafts.Thus, Motor drive shaft rotate, main shaft drive pinch roll rotate, thus ensure that two pinch rolls against place Sandwich medicated napkin paper delivery.

In some embodiments, swing mechanism includes rotating shaft, axle sleeve, connecting rod and the second bearing, the Two bearings are eccentrically mounted in the other end of two main shafts, and are resisted against connecting rod, one end of connecting rod connection rotating shaft, Two gripper shoes are fixed on by axle sleeve respectively in the two ends of rotating shaft, rotating shaft between two gripper shoes, rotating shaft Being provided with at least two shift forks, each shift fork be arranged in parallel.Thus, main shaft rotarily drive the second bearing Rotating, the second bearing eccentrically mounted makes it possible to promote connecting rod swing, connecting rod drive axis of rotation from And rotating shaft drives each shift fork to swing, medicated napkin can uniformly be released by parallel shift fork.

This utility model simple in construction, efficiently avoid the event producing paperboard when medicated napkin paper delivery folds Barrier.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in further detail.

As shown in Figure 1, 2, this drawing mechanism includes frame 1, two pinch roll 2, shift fork 3, rotating machine Structure 4 and swing mechanism 5, the outer rim of two pinch rolls 2 abuts, frame 1 includes two gripper shoes 11 With four support columns 12, two parallel gripper shoes 11 are by four support columns 12 being perpendicular to gripper shoe 11 Bolt is fixed.Rotating mechanism 4 includes motor, two main shafts 41, clutch shaft bearing 42 and bearing block 43, A two main shafts 41 sheathed pinch roll 2 respectively, each main shaft 41 two ends are provided with clutch shaft bearing 42 and axle Bearing 43, bearing block 43 bolt respectively is fixed on two gripper shoes 11, and motor passes through gear drive Power connects one end of two main shafts 41.

Swing mechanism 5 includes rotating shaft 51, axle sleeve 52, connecting rod 53 and the second bearing 54, the second bearing 54 is eccentrically mounted in the other end of two main shafts 41 by sleeve axle 55, and the second bearing 54 is resisted against connecting rod 53, connecting rod 53 bolt is fixed on one end of rotating shaft 51, and the two ends of rotating shaft 51 are respectively by axle sleeve 52 Being fixed on two gripper shoes 11, rotating shaft 51 is placed between two gripper shoes 11, and is perpendicular to two gripper shoes 11, Rotating shaft 51 is provided with four shift forks 3, and each shift fork 3 be arranged in parallel, and every shift fork 3 pinches along corresponding The outer rim of roller 2 is installed, and one end of every shift fork 3 inserts rotating shaft 51 and bolt is fixed, every shift fork 3 The other end be positioned at two pinch rolls 2 against place 6 or stretch out two pinch rolls 2 against place 6, it is preferable that Be positioned at two pinch rolls 2 against place 6.

During above-mentioned drawing mechanism conveying medicated napkin, medicated napkin is sent into against place 6 along the direction of arrow of Fig. 2, Motor-driven gear drive mechanism also drives two main shafts 41 to rotate, and make two pinch roll 2 synchronous rotaries, So that medicated napkin sandwiches and sends between two pinch rolls 2, the most each main shaft 41 drive sleeve axle 55 and second bearing 54 eccentric rotary and promote connecting rod 53 to swing, thus drive rotating shaft 51 to rotate, enter And drive each shift fork 3 to swing laterally and play paper, and shift fork 3 alternatively swinging of two pinch rolls 2 is released Medicated napkin is folded.As in figure 2 it is shown, the other end of shift fork 3 be positioned at two pinch rolls 2 against place 6, Making shift fork 3 very close to each other with against place 6, shift fork 3 length, along the outer rim of pinch roll 2, works as medicated napkin When sending between two pinch rolls 2, medicated napkin from two pinch rolls 2 against from 6 i.e. swung by shift fork 3 Release, thus ensure that medicated napkin is all the time from the outer rim paper delivery of two pinch rolls 2, it is to avoid napkin folder Enter the gap of shift fork 3 and pinch roll 2, cause the fault of paperboard.

Above-described is only embodiments more of the present utility model.Ordinary skill for this area For personnel, on the premise of creating design without departing from this utility model, it is also possible to make some deformation And improvement, these broadly fall into protection domain of the present utility model.
