At present, the operation of positioning and sampling rubber materials is that initial rubber samples with irregular shapes are directly cut off manually from a rubber compound production line, and after the initial rubber samples are conveyed to a quick inspection chamber, secondary processing operations such as outer circle trimming and the like are carried out on the initial rubber samples, and finally, circular sheet rubber samples to be inspected with uniform appearance are obtained. The following problems exist in the above conventional operations: on the one hand, the initial rubber sample is manually cut, the operation safety is low, and the efficiency can not be obviously improved. On the other hand, the whole rubber sample detection process is complicated and time-consuming due to the fact that secondary processing procedures are added; meanwhile, secondary processing equipment also belongs to small-sized stamping equipment, and the safety is poor when stamping equipment is manually operated, so that potential safety hazards exist. More noteworthy, the glue sample delivery inspection is batch delivery inspection, and a large number of cut initial glue samples are mixed together, so that the correspondence between the initial glue samples and the cutting positions of the original glue materials is difficult to accurately distinguish; after the secondary processing is carried out, the corresponding relation between the rubber sample to be detected and the cutting position of the original rubber material is further disordered due to the manual processing mode, and the position of the original rubber material cannot be traced back after the rubber sample to be detected is detected to be problematic, so that various troubles are brought to the follow-up raw material improvement, the rubber mixing process improvement and the rubber material stability improvement.

Preferably, the fixed frame is in a portal frame shape, two foot ends of the fixed frame are respectively fixed at two sides of the rack, and the material receiving tray is located at one foot end of the fixed frame.

The beneficial effects of the utility model reside in that:

1) the utility model discloses abandoned traditional manual work to examining the sizing material to cut get with secondary operation bring such as work efficiency is low, security a great deal of defect such as poor. Through adopting the mode that ink jet numbering machine and rubber cutting structure combined together, on the one hand, through the unique circumference drive action of rubber cutting machine, realized the online rubber cutting operation of annular sword, need not shut down, efficiency promotes greatly. On the other hand, through the cylinder diameter of control annular sword for the gluey appearance that cuts off just in time accords with the required size of examining gluey appearance of waiting of test machine, need not secondary operation, labour saving and time saving. Particularly, the surface of the rubber sample cut by the rubber cutting machine is sprayed with the code spraying mark by the code spraying end of the code spraying machine in advance, so that once problems are found in subsequent detection, the product can be traced back in time to find the cutting position of the original rubber material, and a solid foundation is obviously provided for subsequent raw material improvement, rubber mixing process improvement and rubber material stability improvement.

In actual operation, the annular knife is driven by the power motor to generate circumferential motion in the same direction as the advancing direction of the sizing material, and an intersection point serving as a phase point exists between the cutting edge of the annular knife and the sizing material. When the cutting edge of the annular knife moves to the intersection point, the advancing speed of the annular knife at the moment is consistent with the advancing speed of the sizing material; when the rubber material is used as a reference object, the annular cutter performs a vertical downward material cutting action, namely, the annular cutter can cut out a wafer-shaped rubber sample meeting the requirement efficiently.

In this way, the sharp cutting edge of the annular knife does not act directly on the relatively soft belt face of the conveyor belt, so that the belt face of the conveyor belt is protected and the service life of the structure is ensured. Simultaneously, even the blade of annular sword is cut deeply because of processing or installation error relatively sizing material also to certain elasticity that elastic plate itself possessed, and the elastic plate also can compensate above-mentioned error with the decurrent elastic action of self to make the elastic plate can stabilize the blade that props the annular sword all the time, finally ensure the utility model discloses a operational reliability and stability.

4) In consideration of the situation that the rubber material is difficult to fall off after the rubber sample is cut by the cutting edge of the annular cutter, the invention avoids the situation by the independently arranged discharging cylinder. Correspondingly, after the rubber sample is initially cut and taken, in order to avoid the rubber sample from being separated from the cylinder cavity of the annular cutter too early, the vacuum adsorption effect of the negative pressure suction head is also needed to ensure that the rubber sample can be always positioned in the cylinder cavity of the annular cutter within a specific time period. Connect the arrangement of material tray, then be used for when annular sword section of thick bamboo chamber has gluey appearance, the annular sword can follow horizontal track and move to the material tray department that connects that is located one of them sufficient end department of mount, and then relies on the air lever top of the cylinder of unloading to move gluey appearance and spit out gluey appearance to connecing material tray department to in subsequent repeated gluey operation of cutting. Meet material tray inner glue appearance and can deliver inspection at any time, the security is higher, and the simple operation degree also can effectively be guaranteed.

For ease of understanding, the specific structure and operation of the present invention will be further described herein with reference to fig. 1-6:

the utility model discloses an automatic bale splitter of spouting sign indicating number on line is the equipment that ink jet numbering machine and online bale splitter combine. In actual use, the glue material a moves on the conveyer belt 12, and the code spraying end 21 of the code spraying machine sprays a specific string of letters or numbers at a specified position, so that a code spraying mark is formed. The circular cutter 32 of the rubber cutting machine cuts off a circular rubber sample with the code-spraying mark on the rubber material a under the condition that the conveying belt 12 does not stop, and then the rubber sample is sent to a material receiving tray 50 beside the conveying belt 12 through a horizontal rail 31 a. Then the rubber material a is punched out of the cylinder cavity of the annular cutter 32 by the discharging cylinder and falls into the receiving tray 50 so as to be conveniently inspected at any time.

In the structure, the utility model discloses a transport belt 12 adopts two sets of belt bodies of arranging side by side, job stabilization and easy maintenance to form double row formula conveyer belt structure, the centre of this two sets of belt bodies is unsettled, perhaps says that the natural clearance that forms between the two sets of belt bodies. Referring to fig. 1-2 and 5, the middle suspension of the two belts is provided with an elastic plate 14 with a horizontal plate surface. When the annular knife 32 shown in fig. 6 performs a circular motion under the action of the parallel double-crank mechanism, the cutting edge of the annular knife 32 is tangent to the surface of the elastic plate 14 at a certain moment, so as to cut off the glue sample at the upper surface of the elastic plate 14.
