Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a strip-through clamping device for a packaging machine. Background Technology

[0002] Clamps, as a common tool, are widely used in various industrial production and daily life. They mainly use two or more movable jaws to clamp and fix objects. The design of clamps is usually optimized according to specific uses to meet the needs of stability, safety and ease of operation of the clamped objects in different operations. Clamps are widely used in many fields. For example, in the processing industry, they can be used on packaging machines to clamp items or materials.

[0003] Traditional packaging machine strip clamping devices mostly have fixed clamping arms and only a single clamping surface, which often means they can only clamp a single type of item or material. For example, flat clamps can only clamp some flat items or materials, and they have limitations when clamping some round or cylindrical materials, resulting in insufficient overall functionality. Utility Model Content

In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] Reference Figure 1-4This utility model provides an embodiment of a packaging machine strip-through clamping device, including a main frame 1, a connecting frame 2 at the top of the main frame 1 (the connecting frame 2 is the part connecting the entire clamp to the equipment operating frame or robotic arm), a movable frame 3 at the bottom of the main frame 1, and a movable groove 4 at the bottom of the main frame 1. A positioning screw 5 is rotatably connected in the movable groove 4, and a movable block 6 is threaded onto the positioning screw 5. The position where the positioning screw 5 contacts the inner wall of the movable groove 4 is positioned and installed by a bearing. The movable block 6 and the movable groove 4 are nested and sliding. In a coordinated configuration, the movable block 6 is fixedly connected to the movable frame 3. A motor 7 is fixedly connected to one end of the main frame 1, and the output end of the motor 7 is fixedly connected to one end of the positioning screw 5. A clamp arm 8 is rotatably connected to the bottom of the movable frame 3. Two sets of the movable frame 3, movable block 6, and clamp arm 8 are configured. The threads on the positioning screw 5 near both ends are reversed. The two movable blocks 6 are connected to the reversed threads on both sides of the positioning screw 5. The motor 7 drives the positioning screw 5 to rotate, causing the movable blocks 6 on both sides to move closer together. The movable block 6 moves the two movable frames 3 closer together, which in turn moves the two clamping arms 8 closer together to clamp items or materials. A locking mechanism is provided between the movable frames 3 and the clamping arms 8, which can stably position and fix the clamping arms 8 after rotation and adjustment. The outer surface of the clamping arms 8 is provided with a clamping surface 17 and a clamping surface 18 on both sides. The clamping surface 17 is flat, and the clamping surface 18 is curved. The flat clamping surface 17 can facilitate clamping of objects with regular or flat surfaces. The clamping surface 18 can be used to clamp some tubular items. Both the clamping surface 17 and the clamping surface 18 have a protective pad 19 on their outer surfaces. The protective pad 19 is made of rubber and has anti-slip textures on its surface. The rubber protective pad 19 can protect the items or materials to be clamped and reduce wear on the surface of the items or materials. At the same time, the rubber material is wear-resistant and durable, which can also protect the clamping arm 8 to a certain extent and reduce wear. The anti-slip textures can improve the stability during clamping.

[0027] The locking mechanism includes a fixed groove 9 located within the movable frame 3 and two locking grooves 16 located on either side of the top of the clamp arm 8. The two locking grooves 16 are symmetrically arranged to correspond to the positioning after the left and right clamping surfaces of the clamp arm 8 are rotated and adjusted. A movable block 10 is slidably connected within the fixed groove 9, and a spring 11 is installed between the top of the inner wall of the fixed groove 9 and the top of the movable block 10. The spring 11 is in a shallow compression state, which can stably push the movable block 10 to be positioned at the bottom of the fixed groove 9. The spring 11 can be made of carbon steel, which provides better durability, is less prone to wear, and also ensures the stability of the structural positioning. A locking block 12 is fixedly connected to the bottom of the movable block 10. A toggle block 13 is located on the outer side of the movable frame 3. One side of the outer surface of the toggle block 13 is set as an inclined surface, and the inclined surface of the toggle block 13... The anti-slip textured surface and the inclined surface enhance the smoothness of the toggle block 13 during operation. A connecting groove 15 is provided on one side of the inner wall of the fixed groove 9. A connecting block 14 is slidably connected in the connecting groove 15. The two ends of the connecting block 14 are fixedly connected to the movable block 10 and the toggle block 13 respectively. The locking block 12 and the two locking grooves 16 are nested together. During operation, the toggle block 13 is slid, and the toggle block 13 drives the movable block 10 to move upward through the connecting block 14. The movable block 10 compresses the spring 11 and at the same time drives the locking block 12 to leave the current position of the locking groove 16, thus opening the locking mechanism. After rotating the clamp arm 8 to switch the clamping surface, the toggle block 13 is released. The spring 11 returns to its original position and pushes the movable block 10 to drive the locking block 12 to insert into the locking groove 16, thus completing the locking operation of the clamp arm 8.

[0028] Working principle: When using the strip-through clamping device of the packaging machine, rotate the clamp arm 8, adjust the corresponding clamping surface, and lock it through the locking mechanism. The motor 7 drives the positioning screw 5 to rotate. The positioning screw 5 drives the moving blocks 6 on both sides to move closer to each other. The two moving blocks 6 drive the two moving frames 3 to move closer to each other. The two moving frames 3 then drive the two clamp arms 8 to move closer to each other, so as to clamp the items or materials.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
