Description

Technical Field

[0001] The present application relates to the technical field of packaging and transportation equipment, and in particular to a clamping and conveying mechanism. Background Art

[0002] In the tray packaging machine, a transport mechanism is required to transport the tray to the sealing and cutting station, seal, inflate and cut the upper film of the tray, and then transport the tray out of the sealing and cutting station. Therefore, a stable and high-speed tray transport mechanism is required.

[0003] Usually, the tray transporting mechanism adopts a clamping method, using friction to clamp the tray from both sides, and then drag the tray forward, but cannot make the tray leave the conveyor belt. In this way, when the tray moves forward driven by the tray transporting mechanism, the tray will rub against the conveyor belt; if the tray is subjected to external force during the transportation process, resulting in a change in friction force, it may cause the tray to fall off, or the tray may be deformed due to the large clamping force. Utility Model Content

[0004] In view of this, the main purpose of the present application is to provide a clamping and conveying mechanism, which is helpful to solve the problem of the tray falling due to changes in the clamping friction force or being deformed due to excessive clamping force during the transmission process.

[0014] From the above, the cylinder provides the power for the clamping arm to open or close, and the cylinder and the first slide bar are connected by two second connecting rods, providing a mechanical connection structure for the opening and closing of the clamping arm; to ensure that the first slide bar can rotate in situ when the cylinder is opened, the second connecting rod is rotatably connected to the connecting block at the upper end of the cylinder and fixedly connected to the first slide bar; the second slide bar below the first slide bar is fixedly connected to the first slide bar through the end plate, so that the second slide bar can rotate with the first slide bar as the axis.

[0015] Optionally, the first driving unit includes: a motor, which is used to drive the transmission fixing member to move; and a transmission fixing member, which is used to drive the sliding frame to move along the two first sliding rods.

[0016] As described above, the motor provides power for horizontal movement of the clamping and conveying mechanism, and the conveying fixture is a connecting structure for the horizontal movement of the clamping and conveying mechanism.

The first slide bar 106 is connected to the second connecting rod 103 through a connecting piece 104, and is connected and fixedly arranged on a connecting block 102 at the upper end of the piston rod of the cylinder 101. A second extension body 1092 is provided at the lower end of the clamping arm 109, and a lifting claw 113 is installed on the second extension body 1092.

And in Figure 2 In the illustrated embodiment, the slope ratio A′ at the end of the lifting claw 113 can be set to 1:2.5.

[0074] It should be noted that the setting of the slope ratio of the end of the lifting claw 113 may vary according to actual conditions.

[0075] Figure 3 FIG. 1 is a side view of a specific embodiment of the clamping and conveying mechanism for transporting the tray 114 of the present application. Figure 3 As shown, the handling process of the clamping and conveying mechanism is shown from the side. When the tray 114 is being packaged, the tray 114 needs to be carried from A to B. After completing the sealing, inflation, and cutting of the upper film at B, the tray 114 at B is carried to C. The cylinder 101 is turned on, pushing the piston rod upward, and the connecting block 102 at the upper end of the piston rod also moves upward, driving the two connecting rods 103 connected to the connecting block 102 to rotate upward. The two connecting rods 103 move upward, and under the action of the connecting member 104, the first slide bar 106 is driven to rotate outward, and then under the action of the end piece 108, the second slide bar 107 is driven to rotate inward, so that the clamping arm 109 is closed inward, and the trays 114 located at A and B directly below it are lifted up at the same time, and the clamping arm 109 moves along Then, the connecting block 102 moves downwards when the piston rod is withdrawn, driving the two connecting rods 103 to move downwards. When the two connecting rods 103 move downwards, the first slide bar 106 is driven to rotate inwards under the action of the connecting member 104, and then the second slide bar 107 is driven to rotate outwards under the action of the end piece 108, so that the clamping arm 109 is opened outwards, and the bracket 114 is placed at B and C. In the open state, the clamping arm 109 returns from CB to BA, waiting for the next movement.

[0076] To summarize, the clamping and conveying mechanism provided in the present application connects the sliding frame 110 with the first driving part through a fixed gasket arranged on the sliding frame 110, and drives the clamping arm 109 to slide by limiting it on both sides of the clamping arm 109 through the sliding frame 110; the second driving part is fixedly connected to the first slide bar 106 through two connecting rods 103 and the connecting piece 104, thereby driving the first slide bar 106 to rotate, and the end pieces 108 are respectively arranged at the two ends of the two first slide bars 106, and the two second slide bars 107 are limited to the bottom of the two first slide bars 106 through the end pieces 108, and can rotate around the first slide bar 106, the first slide bar 106 and the second slide bar 107 provide both a horizontal conveying route and structural support for the opening and closing movement of the clamping arm 109. The two connecting rods 103 and the cylinder 101 provide the power for the opening and closing movement of the clamping arms 109; when the two clamping arms 109 clamp inwardly, the lifting claws 113 at the lower ends of the clamping arms 109 will lift the tray 114 from below the starting edge and make the tray 114 leave the conveyor belt for a certain distance, thereby avoiding the friction between the tray 114 and the conveyor belt and improving the stability of the conveying; the motor 115 and the cylinder 101 are jointly controlled, the motor 115 provides the power for the horizontal movement of the clamping arms 109, the cylinder 101 provides the power for the opening and closing of the clamping arms 109, and the conveying fixing piece 116 and the first The slide bar 106 and the second slide bar 107 provide support for the movement route in the horizontal direction, and the second connecting rod 103 connects the cylinder 101 and the first slide bar 106 to provide a mechanical connection structure for the opening and closing of the clamping arm 109; the clamping and conveying mechanism utilizes the clamping action of the clamping arm 109 to realize the lifting method of the lifting claw 113, which not only improves the stability of the transmission of the tray 114, but also prevents vibration during the clamping process or changes in the clamping force due to other factors, thereby avoiding the tray 114 from falling off during the clamping process, or deformation of the tray 114 due to excessive clamping force.
