Liquid material following conveying mechanism

Abstract

A liquid material following conveying mechanism is formed by connecting a frame, a liquid injection needle and a following driving set. A follow-up driving set is installed on the frame, and a liquid injection needle is installed on the follow-up driving set. The liquid injection device has the advantages that the liquid injection needle can be driven by the servo motor to move up and down synchronously with an external transverse sealing mechanism. Liquid injection, sealing of an external transverse sealing mechanism and material bag traction action can be carried out at the same time, independent time is not needed for completion, meanwhile, liquid materials are prevented from being left in the next material bag and the sealing position in the material bag traction process, and the operation takt of equipment is improved.

Description

Technical Field

[0001] The utility model belongs to the field of packaging machinery, in particular to a liquid material follow-up conveying mechanism. Background Art

[0002] The existing liquid material conveying mechanism is a mechanism for loading liquid into a frame, a liquid injection needle and a back-sealed bag. The injection needle is inserted into the back-sealed bag, the external transverse sealing mechanism seals the bag opening, and the external liquid is loaded into the bag through the injection needle. After the liquid is loaded, the external transverse sealing mechanism pulls the bag downward. After the traction is completed, the transverse sealing mechanism returns to the initial position to seal the next bag opening and wait for liquid injection.

[0003] The above-mentioned prior art has the following problems: the liquid injection into the material bag cannot be carried out simultaneously with the sealing and pulling of the material bag by the external transverse sealing mechanism, and needs to be completed at an independent time. Otherwise, during the pulling of the material bag, the liquid material will remain in the next material bag and the sealing part, affecting the sealing of the material bag. However, such independent operation will affect the beat of the entire equipment. Summary of the invention

[0004] The purpose of the utility model is to solve the above-mentioned existing problems and provide a liquid material following conveying mechanism which improves the operation rhythm of the equipment.

[0005] The utility model is as follows: a liquid material following conveying mechanism, a following driving group is installed on the injection frame, and a liquid injection needle is installed on the following driving group. The servo motor of the following driving group is connected to a ball screw through a coupling, and a ball screw nut and a bearing are installed on the ball screw, and the ball screw nut is installed on a second support frame.

[0006] Furthermore, a slide rail is installed on the first support frame of the frame, and a slider is installed on the slide rail.

[0007] Furthermore, the one-way valve of the injection needle is connected to the adapter sleeve, the adapter sleeve is connected to the retaining ring, and the retaining ring is connected to the liquid outlet.

[0008] The advantages of the utility model are: the injection needle can be driven by a servo motor and move up and down synchronously with the external transverse sealing mechanism. The injection can be carried out simultaneously with the sealing and pulling of the material bag by the external transverse sealing mechanism, and no independent time is required to complete it. At the same time, it avoids the liquid material from remaining in the next material bag and the sealing position during the pulling of the material bag; and improves the operation rhythm of the equipment.

[0013] The following is a detailed description with reference to the accompanying drawings: Figure 1-4 As shown, it comprises an injection frame 1, an injection needle 2, and a follower drive group 3 connected to form a structure; the follower drive group 3 is installed on the injection frame 1, and the injection needle 2 is installed on the follower drive group 3. The slide rail 102 is installed on the first support frame 101 of the frame 1, and the slider 103 is installed on the slide rail 102. The one-way valve 201 of the injection needle 2 is connected to the adapter sleeve 202, the adapter sleeve 202 is connected to the retaining ring 203, and the retaining ring 203 is connected to the liquid outlet 204. The servo motor 301 of the follower drive group 3 is connected to the ball screw 302 through the coupling 304, and the ball screw nut 303 and the bearing 305 are installed on the ball screw 302, and the ball screw nut 303 is installed on the second support frame 306. When in use, the injection needle 2 is inserted into the material bag, and after the external horizontal sealing mechanism seals the bag mouth of the material bag, the material bag is pulled downward. During the process of pulling the material bag, the injection needle 2 starts to inject liquid into the material bag, and at the same time, the servo motor 301 is activated to drive the ball screw 302 to rotate, and the ball screw nut 303 drives the second support frame 306 and the injection needle 2 to move downward with the material bag, ensuring that the relative position of the injection needle 2 and the external transverse sealing mechanism remains unchanged. After the external transverse sealing pulling action and the injection of the injection needle 2 are completed, the servo motor 301 drives the injection needle 2 to follow the transverse sealing mechanism to return to the initial position to prepare for the injection of the next material bag.
