Continuous sealing and cutting machine

Abstract

The embodiment of the invention discloses a continuous sealing and cutting machine. The continuous sealing and cutting machine comprises a machine frame, a drive device, a synchronous filling device, a film covering device, a synchronous sealing and cutting device, and a film collecting device, wherein the synchronous filling device comprises a material storage unit and a feeding unit; the material storage unit is fixedly arranged on the machine frame; the feeding unit is arranged on the material storage unit by a sliding rod and is fixedly connected with the synchronous sealing and cutting device by a connecting rod; the synchronous sealing and cutting device comprises a hot sealing and cutting mechanism and a first servo motor; the hot sealing and cutting mechanism comprises a hot sealing and cutting unit and a hot sealing unit; the hot sealing and cutting mechanism is connected with the feeding unit through the connecting rod; and the hot sealing and cutting mechanism and the feeding unit act synchronously under the drive of the first servo motor. By adopting the continuous sealing and cutting machine, the continuous sealing and cutting machine is kept static relative to a template when the processes of filling and sealing are finished, and the template does not need to be stopped conveying momentarily, so that the work efficiency is improved; in addition, the continuous sealing and cutting machine is also provided with a sealing and cutting component replacement device and a film calibrating device, so that the continuous sealing and cutting machine is suitable for different templates, the equipment university is improved and the production investment is reduced.

Description

technical field [0001] The invention relates to a container film sealing device, in particular to a continuous sealing and cutting machine in which the template is not suspended for transmission during heat sealing and cutting. Background technique [0002] At present, the heat sealing machine used in the prior art generally includes a transmission device, a filling device, a film covering device, a heat sealing and cutting device, etc., usually these parts are independent parts, that is, independent in the process, and the transmission device is to be processed during processing. When the container is transported to the filling device, the transmission device stops running. After the container is filled with material, the transmission device starts again, and the container is transported to the heat sealing and cutting device. It pauses again, and the film coating device covers the container, and then Heat sealing and cutting is performed by a heat sealing and cutting devic...

Problems solved by technology

[0002] At present, the heat sealing machine used in the prior art generally includes a transmission device, a filling device, a film covering device, a heat sealing and cutting device, etc., usually these parts are independent parts, that is, independent in the process, and the transmission device is to be processed during processing. When the container is transported to the filling device, the transmission device stops running. After the container is filled with material, the transmission device starts again, and the container is transported to the heat sealing and cutting device. It pauses again, and the film coating device covers the container, and then Heat sealing and cutting is performed by a heat sealing and cutting device. During this process, since the filling device, film covering device, and heat sealing and cutting device are not connected, the processing process needs to be stopped many times, and the processing efficiency is low. It is not suitable for mass production, and the film covering device The inability to synchronize and accurately control the conveying film according to the actual length of the film required also causes a waste of materials to a certain extent. In addition, during the processing process, since the molds of the heat sealing and cutting devices in the prior art are generally fixed, it is difficult to replace the heat. Sealing and cutting molds and knives are suitable for processing of different shapes. The equipment is not very versatile, and the investment cost is high when processing products of different specifications and shapes.
