[0007] When the connecting seat is in the first position, all clamping components change from a released state to a clamped state. When the connecting seat drives the clamping components to move to the second position, all clamping components change from a clamped state to a released state, and then the connecting seat is reset to the first position.

[0008] The connecting seat is driven to reciprocate on the frame by the actuator, and combined with the opening and closing movement of the clamping assembly, the packaging film is intermittently and stably transported along each workstation. During the process of resetting the connecting seat from the second position to the first position, the packaging film does not move, and each workstation is just working on the packaging film, and the entire transportation is very stable.

Features defined as "first" or "second" may explicitly or implicitly indicate that at least one of the features is included.

[0022] like Figure 1-Figure 3 A conveying device shown in the figure comprises a connecting seat 10 slidably connected to a frame distributed along a plurality of workstations, an actuator 20 driving the connecting seat 10 to reciprocate, a clamping assembly 30 is provided at a position corresponding to each workstation on the connecting seat 10; the connecting seat 10 has a first position for moving the clamping assembly 30 to an initial state and a second position for synchronously moving all the clamping assemblies 30 backward by one workstation; the clamping assembly 30 has a clamping state for clamping a packaging film and a releasing state for loosening the packaging film; the actuator 20 comprises a base 200 for connecting to the frame, a motor 201 fixed on the base, a screw rod 202 is provided at the shaft end of the motor 201, a wire seat 203 is provided on the screw rod 202, the wire seat 203 is slidably connected to the base 200, and the connecting seat 10 is connected to the wire seat 203;

[0023] When the connecting seat 10 is in the first position, all clamping components 30 change from the released state to the clamped state. When the connecting seat 10 drives the clamping components 30 to move to the second position, all clamping components 30 change from the clamped state to the released state, and then the connecting seat 10 is reset to the first position.

[0024] In some embodiments, the connection seat 10 is configured as two parallel connection rods 100 , and a sliding seat 101 connected to the frame is provided on the connection rod 100 , and the connection rod 100 passes through the sliding seat 101 to form a sliding connection.

[0025] The wire seat 203 is provided with a locking assembly 21 connected to the connecting seat 10, and the locking assembly 21 includes a fixing seat 210 and a plurality of hoops 211; the fixing seat 210 is fixedly connected to the wire seat 203, and the upper end of the fixing seat 210 is provided with two slots 212, and the two connecting rods 100 are correspondingly inserted into the two slots, and the connecting rods 100 are locked and positioned at both ends of the slots by the hoops 211. In some embodiments, the hoops are formed of two semicircular ring structures, and the arc-shaped openings of the two semicircular rings are butt-jointed to clamp the connecting rods and then locked by bolts.

[0026] The clamping assembly 30 corresponding to the first workstation at the front end is configured as the first clamping assembly 31, and the remaining clamping assemblies 30 are configured as the second clamping assemblies 32; the structure of the first clamping assembly 31 is as follows Figure 2 As shown, specifically: the first clamping assembly 31 includes a first clamping seat 310 and a first power 311. The first clamping seat 310 is provided with a film guide groove 312 for the packaging film to pass through, and a pressure plate 313 is provided on one side of the film guide groove 312. The first power 311 is fixed on one side of the first clamping seat 310 and connected to the pressure plate 313.

[0027] The first clamping seat 310 is slidably connected to the connecting seat 10. The sliding direction of the first clamping seat 310 is parallel to the movement direction of the connecting seat 10. The connecting seat 10 is provided with a translational force 11 for driving the first clamping seat to move. The translational force in this embodiment is configured as a cylinder. In the process of the connecting seat 10 moving from the first position to the second position, the translational force 11 drives the first clamping seat 310 and the connecting seat 10 to move in the opposite direction, so that the packaging film between the first clamping component 31 and the adjacent second clamping component 32 is flattened. When the connecting seat 10 moves to the second position and the first clamping component 31 is in a released state, the translational force 11 drives the first clamping component 31 to reset. The first clamping component is driven to translate by the translational force. In the process of the connecting seat moving from the first position to the second position (this process is the feeding process), the translational force drives the first clamping component to move in the opposite direction, thereby pulling the packaging film and tightening the packaging film, which is convenient for subsequent preheating and packaging of the packaging film and prevents the packaging film from wrinkling.

[0028] like Figure 4 As shown, the second clamping assembly 32 includes a second clamping seat 320, two clamping plates 321 on the second clamping seat, and a second power 322 for driving the clamping plates to move. The second clamping seat 320 is fixed on the connecting seat 10. Under the action of the second power 322, the two clamping plates 321 have a clamping state of clamping the packaging film close to each other and a releasing state of moving away from each other.

[0029] In conjunction with the accompanying drawings, the principle of the utility model is as follows: the motor 201 and the screw rod 202 drive the wire seat 203 to reciprocate, and the wire seat is connected to the connecting rod through the locking assembly, thereby driving the connecting rod to reciprocate, the length direction of the connecting rod is parallel to the distribution direction of the workstations, and the movement distance of the wire seat corresponds to the distance between the workstations; when the connecting rod is in the first position, all the clamping components clamp the packaging film, and in the process of the packaging film moving from the first position to the second position, the translational force drives the first clamping component to move in the opposite direction, thereby tightening and flattening the section of packaging film between the first clamping component and the adjacent clamping component, preventing the packaging film from wrinkling and improving the molding quality of the packaging film; when the wire seat moves to the second position, at this time, all the packaging films move from the previous workstation to the next workstation, and then all the clamping components are released and reset to the first position (translational force is reset synchronously), and the packaging film does not move during the reset process, and each workstation is just working on the packaging film; repeating the above work, intermittent conveying of the packaging film is realized, and the overall structure is simple and stable.
