Technical Field

[0001] This utility model belongs to the field of automatic packaging machine gripper technology, specifically a rear-opening hygienic gripper. Background Technology

[0002] A packaging machine is a specialized piece of machinery used to complete the product packaging process. It combines products with packaging materials through automated or semi-automated methods to create finished packages that offer protection, sealing, and aesthetic appeal. Its core functions are to improve packaging efficiency, ensure packaging quality, reduce labor costs, and meet the needs of products in storage, transportation, and sales. Among these aspects, the gripper mechanism is particularly important in packaging machines.

[0003] In existing automatic packaging machines, the transportation of packaging bags between different workstations is achieved by gripping the packaging bags with a clamp, and then the power mechanism drives the clamp to move, thus realizing the movement of the packaging bags between different workstations. It can be seen that the clamp is an important unit module in the packaging machine.

[0004] However, the drive springs of the grippers are generally exposed, which allows dust to accumulate on the springs. Furthermore, the gripper structure is generally front-opening, which requires a horizontal arrangement, resulting in a larger gripper width. This further leads to a larger radius of the packaging machine turntable, requiring the packaging machine to have greater power and more space for installation. Therefore, a rear-opening hygienic gripper is proposed to address the above problems. Utility Model Content

The positioning and locking mechanism includes a positioning block and a locking rod. The locking rod is located above the positioning block. A gripping opening and closing drive mechanism is provided on the positioning block, and a set of gripping mechanisms is symmetrically arranged below the gripper frame.

[0007] Preferably, the clamping mechanism includes a rotating base, on which a gripper body is integrally formed, and a gripper slidably connected to the gripper body. A rotating rod is hinged to the rotating base, with a ball fixedly mounted at one end of the rotating rod, and the other end of the rotating rod hinged to a pin of the gripper. A spring seat is fixedly mounted on the rotating base, and a spring is mounted on the spring seat.

[0008] Preferably, the gripper has a through cavity on its inner side, the spring seat is slidably connected to the through cavity, and the spring is disposed in the through cavity.

[0009] Preferably, the outer side of the pulled-back gripper and the gap between the gripper body form a gripper opening, and the two gripper openings are arranged facing each other.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figures 1-6 This utility model provides a rear-opening hygienic gripper, including a packaging machine turntable 1; the packaging machine turntable 1 has an installation groove 2, and a locking groove 3 is provided above the packaging machine turntable 1. A gripper frame 4 is detachably installed on the installation groove 2. The gripper frame 4 is provided with a positioning and locking mechanism. The positioning and locking mechanism connects and positions the gripper frame 4 with the packaging machine turntable 1, quickly locking and completing the positioning and installation work, greatly saving installation and debugging time and improving production and maintenance efficiency. The positioning and locking mechanism includes a positioning block 5 and a locking rod 6. The locking rod 6 is located above the positioning block 5. The positioning block 5 is provided with a clamping opening and closing drive mechanism, which is used to drive two clamping mechanisms. A set of clamping mechanisms is symmetrically arranged below the gripper frame 4 to clamp the workpiece.

[0029] Furthermore, such as Figure 1 and Figure 5As shown, the clamping mechanism includes a rotating base 7, on which a gripper body 8 is integrally formed. A gripper 9 is slidably connected to the gripper body 8. A rotating rod 10 is hinged to the rotating base 7. A ball 18 is fixedly mounted at one end of the rotating rod 10, and the other end of the rotating rod 10 is hinged to the pin of the gripper 9. A spring seat 11 is fixedly mounted on the rotating base 7, and a spring 12 is mounted on the spring seat 11. By moving the end of the ball 18, the rotating rod 10 is hinged, thereby connecting the pin and the rotating rod 10 to form a linkage. This drives the gripper 9, causing it to move and open the clamping opening. The spring 12, mounted on the spring seat 11, is placed in the cavity 13 inside the gripper 9 to form a reset mechanism. The spring seat 11 and the spring 12 achieve the reset and retention of the clamping mechanism.

[0030] Furthermore, such as Figure 5 As shown, a through cavity 13 is provided on the inner side of the gripper 9. The spring seat 11 is slidably connected to the through cavity 13, and the spring member 12 is disposed in the through cavity 13. With this structure, a reset mechanism is formed in the through cavity 13 inside the gripper 9, and the reset and retention of the clamping mechanism is achieved through the spring seat 11 and the spring member 12. The spring member 12 placed through the through cavity 13 can prevent the spring member 12 from being contaminated.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, the gap between the outer side of the pulled-back gripper 9 and the gripper body 8 forms a gripper opening 14. Through the structural arrangement of the gripper opening 14, the gripper 9 moves back to open the gap with the gripper body 8, the bag enters the gap, the clamping mechanisms on both sides reset, and the gripper 9 resets to clamp the bag.

[0032] Furthermore, such as Figure 3 and Figure 4 As shown, the clamping opening and closing drive mechanism includes shaft holes 15 respectively opened on both sides below the positioning block 5. A rotating shaft 16 is fixedly installed on the top of the rotating base 7. The corresponding rotating shaft 16 is rotatably connected to the shaft hole 15. An opening and closing drive hinge 17 is provided between the rear of the two rotating bases 7. Through the structural configuration of the clamping opening and closing drive mechanism, the two clamping mechanisms are driven. Simply pull the opening and closing drive hinge 17. At this time, the rotating shaft 16 of the rotating base 7 on both sides of the clamping mechanism rotates in the shaft hole 15, thereby moving the gripper body 8, so that the gripper 9 clamps the workpiece.

[0033] Furthermore, such as Figure 1 As shown, the positioning block 5 and the mounting groove 2 are interlocked, and the locking rod 6 and the locking groove 3 are interlocked. This structure facilitates the connection and positioning of the clamping device frame 4 and the packaging machine turntable 1, and quickly locks to complete the positioning and installation work, which greatly saves installation and debugging time and improves production and maintenance efficiency.

[0034] Working principle: When using the hygienic gripper to open and close,

[0035] By using the positioning and locking mechanism, the clamping device frame 4 is connected and positioned to the packaging machine turntable 1, and the positioning and installation work is completed quickly and locked, which greatly saves the installation and debugging time and improves the production and maintenance efficiency. By inserting the positioning block 5 into the installation slot 2 of the packaging machine turntable 1 and locking the locking rod 6 into the locking slot 3 of the packaging machine turntable 1, the clamping device frame 4 and the packaging machine turntable 1 can be installed.

[0036] The clamping opening and closing drive mechanism is designed to achieve the action of the gripper 9 and the rotating rod 10. The clamping mechanisms on both sides expand outward, the ball 18 on the rotating rod 10 is subjected to force, the gripper 9 moves backward to open the gap with the gripper body 8, the bag enters the gap, the clamping mechanisms on both sides reset, and the gripper 9 resets to clamp the bag.

[0037] By designing the clamping mechanism and positioning the clamping opening and closing drive mechanism transmission structure on the vertical surface, the width of the gripper 9 is reduced, further reducing the size of the packaging machine's turntable. Meanwhile, a spring 12 is provided on the spring seat 11 and placed in the through cavity 13 inside the gripper 9, making the spring 12 less prone to contamination. By moving the end of the ball 18, the rotating rod 10 is hinged, thereby connecting the pin and the rotating rod 10 to form a linkage. This drives the gripper 9, causing it to move and open the clamping port. A spring 12 is mounted on the spring seat 11 and placed in the through cavity 13 inside the gripper 9 to form a reset mechanism. The spring seat 11 and the spring 12 achieve the reset and retention of the clamping mechanism. The inner side of the gripper 9 has a through cavity 13, and the spring seat 11 is slidably connected to the through cavity 13. The spring 12 is placed in the through cavity 13. Through this structure, the spring 12 placed in the through cavity 13 inside the gripper 9 forms a reset mechanism, and the spring seat 11 and the spring 12 achieve the reset and retention of the clamping mechanism. The spring 12 placed through the through cavity 13 is less likely to be contaminated.
