Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a tooling for installing a bag opening component of a packaging machine. Background Technology

[0002] Traditional packaging machine bag-opening mechanisms lack clear positioning and tooling support during installation. Installers often have to support the suction pipe with one hand and tighten screws with the other, which is inconvenient and affects installation accuracy. This prevents installers from focusing their full attention on adjusting the position, significantly reducing the final precision. This tooling was designed to solve this problem. Utility Model Content

[0003] The purpose of this utility model is to provide an installation fixture for the bag opening component of a packaging machine. This utility model solves the problems of traditional installation, such as the need to hold the suction pipe by hand, low precision, and inconvenient operation. It has the advantages of convenient installation, accurate positioning, and reduced operating intensity.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A packaging machine bag-opening assembly mounting fixture includes a profile, a bottom nylon block, and an upper nylon block. The bottom nylon block is fixedly connected to the bottom of the profile, and the upper nylon block is fixedly connected to the top of the profile. The bottom nylon block has a groove that fits into the gap of the packaging machine's loading section upright plate for overall positioning of the fixture. The upper nylon block has a notch that matches the diameter of the suction pipe of the packaging machine's bag-opening assembly, and the upper nylon block has positioning surfaces that fit against the upper, lower, and back surfaces of the suction head fixing block for positioning and support of the suction pipe and the suction head fixing block. The profile, bottom nylon block, and upper nylon block are connected as a whole by internal hexagonal screws.

[0005] Furthermore, the groove of the bottom nylon block is rectangular, the width of the groove is adapted to the thickness of the upright plate of the bag-feeding part, and the depth of the groove is not less than the protruding length of the upright plate of the bag-feeding part.

[0006] Furthermore, the notch in the upper nylon block is arc-shaped, the diameter of the arc-shaped notch is equal to the outer circumferential diameter of the suction pipe, and there are two notches, corresponding to the upper suction pipe and the lower suction pipe of the bag opening assembly, respectively.

[0007] Furthermore, the profile is an aluminum profile with a rectangular cross-section, and the length of the aluminum profile is not less than the distance between the upper nylon block and the bottom nylon block.

[0008] Furthermore, the number of hexagon socket screws is at least four, with two penetrating the bottom nylon block and connecting to the bottom of the profile, and the other two penetrating the upper nylon block and connecting to the upper part of the profile.

[0009] Furthermore, the positioning surfaces of the upper nylon block and the suction head fixing block include an upper positioning surface, a lower positioning surface, and a rear positioning surface. The upper positioning surface is parallel to and fits against the upper surface of the suction head fixing block, the lower positioning surface is parallel to and fits against the lower surface of the suction head fixing block, and the rear positioning surface is perpendicular to and fits against the back surface of the suction head fixing block.

[0010] Furthermore, both the bottom nylon block and the upper nylon block are made of nylon 66, and the hardness of nylon 66 is Shore D70-D80.

[0011] This invention offers the following advantages: Traditional installation requires operators to hold the suction pipe with one hand and tighten the screws with the other, a cumbersome and laborious process. This fixture supports the suction pipe through a notch in the upper nylon block, while the bottom nylon block fixes the fixture's position, eliminating the need for manual lifting. This allows operators to focus on tightening the screws and fine-tuning the position, significantly simplifying the installation process. The upper nylon block has a contoured structure; its notch diameter matches the suction pipe, and its positioning surface precisely fits the upper and lower surfaces and back of the suction head fixing block, ensuring the relative position of the upper and lower suction pipes is fixed and effectively guaranteeing the parallelism of the upper and lower suction heads. This solves the problem of suction head angle deviation caused by unstable manual lifting in traditional installations, avoids bagging failures due to non-parallel suction heads, and improves the production stability of the packaging machine.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figure 1 As shown, one embodiment of this utility model is provided: a packaging machine bag opening component installation fixture, including a profile 1, a bottom nylon block 2, an upper nylon block 3, and an internal hex screw 4.

[0016] Profile 1: An aluminum profile with a cross-section of 80mm×40mm and a length of 300mm is used as the main support frame of the tooling. Its material has high strength and lightweight characteristics, which can ensure the overall structural stability and facilitate handling and operation.

[0017] Bottom Nylon Block 2: Made of Nylon 66 material (Shore hardness D75), it is integrally molded and fixed to the bottom of profile 1. Its bottom has a rectangular groove 21 with a width of 15mm and a depth of 20mm. The size of the groove 21 is adapted to the thickness (15mm) and protrusion length (18mm) of the vertical plate of the packaging machine's bag-feeding section. It is used to lock the tooling into the gap of the vertical plate for positioning and to prevent the tooling from shifting during installation.

[0018] Upper Nylon Block 3: Also made of Nylon 66 material (Shore hardness D75), it is fixed to the upper part of the profile 1 and has a contour-following structure. It has two arc-shaped notches 31 with a diameter of 50mm, which precisely match the outer diameter (50mm) of the suction tube 5 in the bag opening assembly, and are used to fit and support the suction tube. The upper nylon block 3 also has an upper positioning surface 32, a lower positioning surface 33 and a rear positioning surface 34. The upper positioning surface 32 is parallel to the lower positioning surface 33 (with a spacing of 40mm) and fits against the upper and lower surfaces (with a spacing of 40mm) of the suction head fixing block. The rear positioning surface 34 is perpendicular to the upper and lower positioning surfaces and fits against the back of the suction head fixing block. Omnidirectional positioning of the suction head fixing block is achieved through three-sided contact.

[0019] 4 socket head cap screws: M8 size, 4 in total. Two of them pass through the bottom nylon block 2 and connect to the bottom threaded hole of the profile 1. The other two pass through the upper nylon block 3 and connect to the upper threaded hole of the profile 1. The three are fastened into a whole to ensure that the tooling does not loosen during use.

[0020] In this invention, profile 1 serves as the skeleton of the tooling, connecting the bottom nylon block 2 and the upper nylon block 3. Its length and cross-sectional dimensions are designed to ensure that the height of the upper nylon block 3 matches the installation height of the suction pipe of the bag-opening assembly 6, providing a stable support foundation for the entire tooling and preventing deformation due to stress from affecting positioning accuracy. The bottom nylon block 2's core function is to achieve positioning between the tooling and the packaging machine. After the rectangular groove 21 is engaged with the upright plate of the bag-feeding section, it restricts the horizontal movement and vertical rotation of the tooling, ensuring that the position of the upper nylon block 3 precisely corresponds to the installation position of the suction pipe, which is a prerequisite for ensuring the subsequent positioning accuracy of the suction pipe. The upper nylon block 3 is a key component for achieving suction pipe positioning. The arc-shaped notch 31 wraps around the outer periphery of the suction pipe, providing radial support and preventing the suction pipe from shaking. The upper positioning surface 32, lower positioning surface 33, and rear positioning surface 34 are in contact with the corresponding surfaces of the suction head fixing block. Through surface contact, the vertical and horizontal displacement of the suction head fixing block is restricted, ensuring that the parallelism error of the upper and lower suction pipe axes does not exceed 0.5mm, meeting the packaging machine's process requirements for suction head parallelism (≤1mm). The internal hex screw 4: By penetrating the connecting profile 1, the bottom nylon block 2, and the upper nylon block 3, the dispersed components are fastened into a unified structure, avoiding positioning deviations caused by relative movement of components during installation and ensuring the structural stability of the tooling.

[0021] Tooling positioning: Align the groove 21 of the bottom nylon block 2 with the gap of the vertical plate of the packaging machine's bag feeding section, and insert it vertically until the groove 21 is completely fitted with the vertical plate. At this point, the overall position of the tooling is fixed.

[0022] Installation of the suction pipe: Assemble the suction pipe, suction head fixing block, suction head and other peripheral parts of the bag opening component in advance, and let the suction pipe hang down naturally; fit the upper and lower suction pipes into the two arc-shaped notches 31 of the upper nylon block 3 respectively, and adjust the position of the suction head fixing block so that its upper and lower surfaces and back are completely in contact with the upper positioning surface 32, lower positioning surface 33 and rear positioning surface 34 of the upper nylon block 3 respectively.

[0023] Tightening and fixing: After confirming that the positions of the suction pipe and suction head fixing block are correct, the operator uses both hands to hold the tool and tighten the screws of the clamping block connecting the suction pipe and the bag opening arm to complete the installation.

[0024] Through the above process, the tooling achieves precise positioning and stable support of the suction pipe without the need for manual lifting, and ensures the parallelism of the upper and lower suction heads, effectively solving the pain points in traditional installation.

[0025] 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.
