Description

Bamboo pulp stock form cutting device

Technical Field

The invention relates to the technical field of toilet paper processing, in particular to a bamboo pulp roll paper cutting device.

Background

In the process of processing the bamboo pulp paper, the bamboo pulp paper is rolled into a cylinder by the paper rolling machine, and the bamboo pulp paper is rolled by the paper rolling machine and then sent to a cutting device to be cut into a plurality of sections with equal length by a cutting machine. However, the two ends of the roll paper wound by the paper winding machine are not flat, the circle center of the first cut end of the cylindrical roll paper protrudes outwards, and the circle center of the second cut end of the cylindrical roll paper is sunken inwards. When the existing cutting device cuts the bamboo pulp roll paper, the push plate moves equidistantly in a clamping groove formed by two clamping plates, so that the roll paper is pushed to move equidistantly in the axial direction, and the length of the cut roll paper is the pushing distance. According to the cutting mode, due to the fact that the push plates are pushed equidistantly, the protruding length of the first cutting end (namely the first cutting end) of the bamboo pulp roll paper can be within the pushing distance, the end face of the roll paper section cut by the first cutting end is not flat, the length of a qualified part is insufficient, and the length of the qualified part of the roll paper section cut by the second cutting end (namely the second cutting end) is too long. Unqualified roll paper section in both ends can be retrieved and rebuilt, will cause the very big waste of production resource like this, has improved manufacturing cost. It is also dangerous to workers if the adjustment is made manually to let the cutter remove both ends of the roll paper.

Disclosure of Invention

The invention aims to solve the problem of providing a bamboo pulp roll paper cutting device, which can enable the uneven surface not to be counted in the cutting length when the roll paper is cut in equal length, so that the cut roll paper sections reach the standard, and the waste of production resources is avoided.

The scheme is basically as follows:

the utility model provides a bamboo pulp stock form cutting device, is including the grip block that is used for the centre gripping stock form, still includes the board that supports of being connected with the grip block and leans on board sliding connection have can with the stock form cut earlier the touch panel that the end centre of a circle offseted.

Therefore, the protruding part of the first cutting end of the roll paper is sunken into the abutting plate, and when the cutting machine is used for cutting, the protruding length of the first cutting end cannot be counted in the cutting length with the same length. The paper winding section cut firstly has uneven surfaces, and the section can be cut again after being subsequently inverted, so that the cutting length can be ensured. After the first section is cut, the end face of one end of the roll paper is flat, the flat end face abuts against the abutting plate, and the roll paper sections cut subsequently are all equal in length. The length of the cut roll paper section can reach the standard, and the waste of resources is avoided.

Further, the clamping plate is connected with a driving device capable of driving the abutting plate to move axially, and the touch plate is connected with a triggering assembly capable of triggering the driving device to brake.

The trigger subassembly can be trigger drive arrangement's switch, if the stock form cuts the end protrusion unevenness earlier, can make the touch panel support relatively to lean on the board to slide, the touch panel slides and lets drive arrangement braking through trigger subassembly to let and support and lean on the board axial displacement, thereby support and promote the stock form and move along the axial opposite direction by supporting the board, let the stock form withdraw a section distance, thereby can get rid of earlier the unevenness face of cutting the end earlier, relative basic scheme, its one section that cuts down earlier need not follow-up reversal cut once more.

Further, still include the push pedal, push pedal sliding connection has the fixed plate, is equipped with the gliding first elastic component of push pedal that can promote between fixed plate and the push pedal.

When drive arrangement drives and supports the board and push back the stock form like this, first elastic component can compress and offset the distance that pushes back to let the fixed plate need not reverse movement.

Further, the trigger assembly includes an electrical contact rod and an electrical contact blade that are electrically connectable.

The trigger assembly may employ an electrical contact rod for mechanically controlling the switching of the drive, where the electrical contact rod and the electrical contact are employed, and the contact and separation of the electrical contact rod and the electrical contact effects the opening and closing of the drive. And the stability and the sensitivity can be ensured by relatively directly controlling the switch.

Further, the touch panel is connected with a second elastic member capable of resetting the touch panel. Guarantee that the touch panel can automatic re-setting after leaning against the board relatively and sliding.

Further, the abutting plate is provided with a through hole with the radius smaller than that of the roll paper, and the abutting plate is in sliding connection with the touch plate through the through hole.

Like this the touch panel with lean on board sliding connection more stable, the through-hole radius is less than the stock form radius simultaneously and can prevent in the outer circumference entering through-hole of stock form tip, and the smooth face can not promote the touch panel and remove, the touch panel only reacts convex uneven face like this to guarantee the accuracy of triggering.

Further, the driving device is a servo electric cylinder or a servo air cylinder.

The servo electric cylinder and the servo air cylinder can work only by using a data control device, the trigger assembly can directly feed back information to the control device through an electric signal, and the control device controls the servo electric cylinder or the servo air cylinder to brake. The servo electric cylinder and the servo air cylinder are both used for telescopic reciprocating braking, and compared with a common rotating motor, the servo electric cylinder and the servo air cylinder can reduce a middle transmission mechanism.

Further, the first elastic part and the second elastic part are both compression springs. The compressible length of pressure spring is longer, and first elastic component can let the push pedal retraction distance big, and simultaneously, the elastic restoring force of first elastic component can make the stock form with lean on the board tightly close to support, guarantee that cutting length is accurate.

Further, the fixed plate is fixedly connected with a conveyor belt.

Therefore, the axes of the paper rolls can be pushed to move without manual work, and the production efficiency is improved.

Further, the conveyor belt is driven by a stepping motor.

Step motor intermittent type braking can let bamboo thick liquid stock form cutting time progressive, guarantees that bamboo thick liquid stock form removes equidistant removal.
