Description

Technical Field

[0001] This utility model relates to the field of packaging machine accessories technology, and in particular to a clamp for packaging machines. Background Technology

[0002] Clamps for packaging machines are an indispensable and important component of packaging machinery. They play a key role in fixing, positioning and guiding workpieces during the packaging process.

[0003] The existing literature on clamps for fully automatic bag packaging machines (CN202828186U) can be referenced. The reference changes the traditional method of using a swing arm and screw to control the distance between the two clamps. Instead, it uses meshing gears to control the distance between the two clamps. This method is easy to control, simple to operate, and has a reasonable structural layout. The size of the gears can be selected according to the required distance between the two clamps to control the distance, making it widely applicable.

[0004] Clamps are widely used in packaging machines. They can be used to fix and position workpieces or bags of various shapes and sizes. As shown in the above literature, the clamps currently used in packaging machines are generally designed for workpieces or bags, and the types of clamps used are also different. Therefore, multiple clamps are needed to adapt to different clamped objects. It is difficult to adjust a single clamp according to actual usage requirements, and the scope of application is limited. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamping fixture for packaging machines. This invention involves installing an extension housing on the docking seat. The auxiliary clamping components inside the extension housing can clamp and fix the packaging bag. When clamping workpieces, the extension housing is not required. Furthermore, the extension housing can be installed on any of the four sides as needed, thus improving the applicability of the clamping fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clamp for a packaging machine includes: a docking seat, with T-shaped slots on all four sides of the docking seat, and positioning components in each T-shaped slot. Each T-shaped slot is composed of a square slot and a rectangular slot connected together. The positioning components are all located in the rectangular slot. A matching docking block is installed in the square slot of one of the T-shaped slots. The docking block is fixed in the square slot by the positioning components. An extension housing is installed on the surface of each docking block. The extension housing contains an auxiliary clamping component, which includes two counter-moving packaging bag clamps for clamping and fixing the packaging bag.

[0008] The present invention is further configured as a positioning component including: a one-way lead screw connected to the inner wall of the T-groove by a bearing; a threaded sleeve connected to the outside of the one-way lead screw; and two insert rods fixed to the bottom of the threaded sleeve.

[0009] The present invention is further configured such that each of the unidirectional lead screws is connected to a handle at its upper end, and the handle is rotatably connected above the docking seat.

[0010] The present invention is further configured such that each of the four sides of the docking block has two slots, and each of the two insertion rods is connected to the two slots.

[0011] The present invention is further configured as an auxiliary clamping assembly comprising: a servo motor fixedly installed at one end of the extension housing; a bidirectional lead screw connected to the output end of the servo motor; and two threaded sleeves threadedly connected to the outside of the bidirectional lead screw, wherein the packaging bag clamps are all fixed to the surface of the threaded sleeves.

[0012] The present invention is further configured to include: a drive housing, wherein cylinders are fixedly installed at both ends of the drive housing, and drive blocks are fixed at the output ends of the cylinders. The two drive blocks are movably installed inside the drive housing, and two guide rods are fixed inside the drive housing. The drive blocks are sleeved on the outside of the two guide rods.

[0013] The present invention is further configured such that a slider is fixed to the upper end of each drive block, the slider is fixed to the bottom of the docking seat, and a clamping platform is fixed above the drive housing, the surface of the clamping platform is provided with a groove for the slider to move.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. When the workpiece needs to be clamped and fixed, the clamp of this packaging machine uses the synchronous operation of two cylinders and the two docking seats to move in opposite directions to clamp and fix both ends of the workpiece. When the packaging bag needs to be clamped and fixed, an extension box can be installed on the docking seat. The auxiliary clamping components inside the extension box can fix both ends of the packaging bag. This allows the clamp to be switched according to the actual object being clamped, without the need to use different types of clamps for different workpieces or packaging bags, thus improving the applicability of this clamp in the packaging machine.

[0016] 2. When installing the extension box of the packaging machine, the fixture has T-slots on all four sides of the docking seat, allowing the extension box to be installed on any side according to actual operating requirements. At the same time, there are two slots on each of the four sides of the docking block, which can adjust the installation angle of the extension box as needed. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0027] Reference Figure 1-5 A clamp for a packaging machine includes: a drive housing 1 and a docking seat 5. Cylinders 4 are fixedly installed at both ends of the drive housing 1. Drive blocks 8 are fixed at the extension and retraction ends of the cylinders 4. The drive blocks 8 slide inside the drive housing 1. The docking seat 5 is connected to the top of the drive blocks 8 through a slider 9. Thus, when the two cylinders 4 run synchronously, they can drive the two docking seats 5 to move in opposite directions.

[0028] Specifically, such as Figure 1 As shown, a clamping platform 2 is fixedly connected to the top of the drive housing 1. A sliding groove 3 is provided on the surface of the clamping platform 2, and the two sliders 9 move within the sliding groove 3.

[0029] In this embodiment, when clamping and fixing the workpiece, the workpiece can be placed above the clamping table 2, and then the two ends of the workpiece can be clamped and fixed by the reverse movement of the two docking seats 5.

[0030] Further details can be found by referring to... Figure 2 The drive housing 1 has two guide rods 10 fixed inside, and the two drive blocks 8 are sleeved on the outside of the two guide rods 10. The two guide rods 10 can ensure the stability of the linear displacement of the drive blocks 8.

[0031] For details, please refer to Figure 3 The four sides of the docking seat 5 are provided with T-shaped grooves 11, and each T-shaped groove 11 is provided with a positioning component. Each T-shaped groove 11 is composed of a square slot and a rectangular slot connected together, and the positioning component is located in the rectangular slot.

[0032] Specifically, the positioning assembly includes a one-way lead screw 12, a threaded sleeve 13, and insert rods 14. The one-way lead screw 12 is connected to the inner wall of the T-slot 11 via a bearing. The threaded sleeve 13 is externally threaded onto the one-way lead screw 12. The threaded sleeve 13 fits the width of the rectangular slot. Two insert rods 14 are fixed below the threaded sleeve 13.

[0033] Meanwhile, four handles 15 are rotatably connected above the docking seat 5, and all four handles 15 are connected to one end of the one-way lead screw 12.

[0034] Therefore, by rotating the handle 15, the one-way lead screw 12 is driven to rotate, which in turn drives the threaded sleeve 13 connected to the external thread of the one-way lead screw 12 to move linearly, so that the two insert rods 14 move synchronously.

[0035] For details, please refer to Figure 4 The square connecting block 6 can be inserted into the square slot. Each of the four sides of the connecting block 6 has two slots 16 that fit the size of the insert rod 14.

[0036] In this embodiment, since the other end of the docking block 6 is connected to the auxiliary clamping component, the docking block 6 can be installed on any of the four sides of the docking seat 5 as required. At the same time, the square docking block 6 can be rotated 90° so that the two insert rods 14 can be inserted into the corresponding slots 16, thereby adjusting the installation angle of the auxiliary clamping component.

[0037] like Figure 5 As shown, the main body of the auxiliary clamping assembly is an extension housing 7. A servo motor 18 is fixedly installed at one end of the extension housing 7. A bidirectional lead screw 17 is fixed at the output end of the servo motor 18. Two threaded sleeves 19 are connected to the external thread of the bidirectional lead screw 17. Packaging bag clamps 20 are fixed above the two threaded sleeves 19.

[0038] In this embodiment, when it is necessary to clamp both ends of the packaging bag, the servo motor 18 can be turned on to drive the bidirectional lead screw 17 to rotate, thereby causing the two threaded sleeves 19 outside the bidirectional lead screw 17 to move in opposite directions around the center of the bidirectional lead screw 17, so that the two packaging bag clamps 20 can move in opposite directions to fix both ends of the packaging bag.

[0039] Working principle: When using this utility model, when clamping and fixing the workpiece, the workpiece can be placed above the clamping table 2. When the two cylinders 4 run synchronously, they can drive the two docking seats 5 to move in opposite directions. Then, the two docking seats 5 move in opposite directions to clamp and fix the two ends of the workpiece. When it is necessary to clamp the two ends of the packaging bag, the servo motor 18 can be turned on to drive the bidirectional lead screw 17 to rotate. This causes the two threaded sleeves 19 outside the bidirectional lead screw 17 to move in opposite directions around the center of the bidirectional lead screw 17. This causes the two packaging bag clamping plates 20 to move in opposite directions to fix the two ends of the packaging bag. Since the other end of the docking block 6 is connected to the auxiliary clamping component, the docking block 6 can be installed on any of the four sides of the docking seat 5 as required. At the same time, the square docking block 6 can be rotated 90° to insert the two insert rods 14 into the corresponding slots 16, thereby adjusting the installation angle of the auxiliary clamping component.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
