Detailed Description
The present invention will be described in further detail with reference to the drawings and the detailed description below, in order to further understand the features and technical means of the present invention and the specific objects and functions achieved.
Referring to fig. 1-8, the automatic express bag production line based on cooperative control of heat seal hot cutting and intermittent conveying comprises a machine body 1, wherein a seal cutting unit 2 and a conveying unit 3 are arranged on the machine body 1, the seal cutting unit 2 comprises a heat seal cutter 21 and a cutter column 22, a separation unit 4 is arranged between the seal cutting unit 2 and the conveying unit 3, the separation unit 4 comprises a lifting plate 41, a follower plate 42, a support 43 and a first spring 44, the lifting plate 41 is arranged on the machine body 1 in a moving manner in the vertical direction, the follower plate 42 is arranged above the lifting plate 41 in the moving manner in the vertical direction, a gap for passing through an express bag 5 is reserved between the lifting plate 41 and the follower plate 42 when the follower plate 42 is at the lowest position, the support 43 is horizontally fixedly arranged on the machine body 1, the first spring 44 is vertically arranged between the support 43 and the follower plate 42, and two ends of the first spring 44 are fixedly connected with the follower plate 42 and the support 43 respectively.
In the production process of the express bags 5, raw materials of the express bags 5 are usually coiled and discharged, sealing of the portable side and punching of a formed portable hole are completed before the sealing and cutting unit 2, and then the raw materials intermittently enter the sealing and cutting unit 2 for heat sealing and hot cutting, so that edge sealing and cutting of express fees are completed. In the prior art, the sealing and cutting unit 2 is mainly used for cutting and segmenting the express bag, the sealing and cutting unit 2 comprises a heat sealing knife 21 and a knife column 22, when cutting is carried out, the express bag 5 passes through the space between the heat sealing knife 21 and the knife column 22, and then the heat sealing knife 21 is heated and lowered and is matched with the knife column 22, so that the sealing and cutting of the express bag 5 are realized. However, after a period of use, the express bag 5 is easy to be cut off completely, and the main reasons include insufficient temperature of the heat sealing knife 21, insufficient sealing and cutting time, abnormal anastomosis of the heat sealing knife 21 and the knife column 22, passivation of the knife edge of the heat sealing knife 21, too small pressure of the heat sealing knife 21 and the like. The knife edge of the heat sealing knife 21 inevitably causes passivation along with the use of the heat sealing knife 21, or the express bag 5 cannot be cut off smoothly due to plastic residues on the heat sealing knife 21, so that the heat sealing knife 21 needs to be maintained regularly, the whole production line needs to be in a shutdown state in the maintenance process, and the heat sealing knife 21 cannot be completely guaranteed to cut off the express bag 5 completely after the maintenance in time. It should be noted that the fact that the express bag 5 cannot be cut off refers to that the express bag 5 cut by the heat sealing knife 21 is in a virtual connection state, but is not in a completely connected state, because when the heat sealing knife 21 cuts the express bag 5, the cut-off state of the express bag 5 is mostly in a virtual connection state due to the assistance of not only the sharpness of the knife edge of the heat sealing knife 21 but also high-temperature heating.
In order to avoid the above-mentioned condition, just carry out optimal design to current express bag 5 automation line, through set up separation unit 4 between sealing and cutting unit 2 and conveying unit 3 for sealing and cutting unit 2 when cutting express bag 5, separation unit 4 produces the effect of dragging to express bag 5 in step, makes express bag 5 can break off completely, has avoided express bag 5 to appear the condition of virtual joint after sealing and cutting, has reduced the frequency to the regular maintenance of heat sealing knife 21, has guaranteed the production efficiency of express bag 5 automation line. The specific structure and working procedure of the present application are as follows:
In the use, firstly, carry express bag 5 to seal cutting unit 2 department, seal cutting unit 2 is passed to the tip of express bag 5 and is stopped moving after appointed length of seal cutting unit 2, seal cutting unit 2 begins to seal cut express bag 5, express bag 5's tip passes seal cutting unit 2 and indicates that express bag 5 passes from between heat sealing knife 21 and knife post 22, and lift plate 41 is located the below of express bag 5 this moment, follower plate 42 is located the top of express bag 5, heat sealing knife 21 descends and coincide with knife post 22 afterwards, heat sealing knife 21 is in the heating state, the cutting rate of heat sealing knife 21 has been improved, stop 0.6~0.8 seconds after heat sealing knife 21 coincide with knife post 22, in this process, lift plate 41 rises, the space between lift plate 41 and the follower plate 42 reduces gradually, with express bag 5 when lift plate 41 rises with the follower plate 42 with express bag 5 centre gripping back, make first spring 44 compressed follower plate 44 and the follower plate 42, the effect of following plate 41 has been avoided following up to the complete compression of express bag 5, the follower plate 42 has been provided with the follower plate 42, the complete drawing of follower plate 41 has avoided following up-up to the complete drawing of the pressure of follower plate 42, the following plate 41 has completely broken the effect of following up-up the express bag 5, the effect of following plate 5 has avoided following up-up to the lift plate 5. The conveying unit 3 is arranged at the rear end of the sealing and cutting unit 2, when the sealing and cutting unit 2 cuts the express bags 5, the conveying unit 3 is in a static state, and after the cutting is completed, the conveying unit 3 is started again and discharges the cut express bags 5.
Through setting up the separation unit 4 between seal cutting unit 2 and delivery unit 3 for lift plate 41 and follower 42 are arranged in vertical direction, and there is the space between lift plate 41 and the follower 42, seal cutting unit 2 seals when cutting express bag 5, express bag 5 is arranged in the space between lift plate 41 and follower 42, when heat-seal knife 21 and knife post 22 coincide, when heat-seal knife 21 and knife post 22 cut express bag 5 promptly, heat-seal knife 21 can not lift immediately, in this process, lift plate 41 rises and drives the follower 42 and rise in step, after the first spring 44 on follower 42 receives the extrusion, first spring 44 provides pressure to follower 42, make lift plate 41 and follower 42 can be with express bag 5 stable centre gripping, when the express bag 5 that is located between plate 41 and follower 42 no longer appears, lift plate 41 and sliding plate continue to rise when just can will be in the express bag 5 and break, the automatic production line of the utility line of the automatic production that has reduced the frequency of drawing off the express bag 5 has guaranteed.
