Description

Technical Field

[0001] This utility model relates to the field of packaging, and in particular to an adjustable bag-holding mechanism for packaging bags. Background Technology

[0002] Packaging refers to wrapping goods or items in specific materials (such as paper, plastic, glass, etc.) or placing them in containers (such as boxes, bottles, etc.) to achieve purposes such as protection, aesthetics, promotion, and portability. Through packaging, goods not only receive physical protection but also visually attract consumers' attention, enhancing their added value and market competitiveness.

[0003] When sealing bagged packaging bags, the bags containing a fixed amount of granular or powdered material need to be conveyed to the sewing station. During the conveying process, there is a risk that the packaging bags may fall or the material may scatter. Therefore, an adjustable bag-holding mechanism is required.

[0004] Currently, when conveying bags filled with materials, symmetrically arranged baffles are typically used to hold the bags in the middle, preventing them from tipping over. However, in actual use, existing baffles can only be adjusted in terms of their spacing, not their height. This fails to prevent bags that are too high or too low from tipping over. Furthermore, current bag-holding mechanisms cannot ensure that the bag opening is locked tightly, which can easily lead to material spilling from the bag opening during the conveying process. Therefore, an adjustable bag-holding mechanism for packaging bags is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable bag-holding mechanism for packaging bags, which aims to improve the problems of non-adjustability of the bag-holding mechanism in the prior art, loose bag openings, and material spillage during the pushing and transporting process.

[0007] As a further description of the above technical solution:

[0008] The sealing component includes an upper bag-supporting pressing strip, the outer side of the upper bag-supporting pressing strip is fixedly connected to the top end of the connecting plate, and a flexible bag-supporting pressing strip is fixedly connected to the inner side of the upper bag-supporting pressing strip.

[0009] As a further description of the above technical solution:

[0010] There are two groups of bag-holding rods, and the two groups of bag-holding rods are symmetrically arranged front and back.

[0011] As a further description of the above technical solution:

[0012] The limiting piece is L-shaped, and the bottom end of the limiting piece contacts the top end of the hollow square tube.

[0013] As a further description of the above technical solution:

[0014] The inner side of the tight-top bolt contacts the outer side of the bag-supporting rod.

[0015] As a further description of the above technical solution:

[0016] The lower bag-supporting pressing strip is V-shaped and made of metal.

[0017] As a further description of the above technical solution:

[0018] The connecting plate is in a "C" shape, and the lower bag-supporting pressing strip and the upper bag-supporting pressing strip are symmetrically arranged up and down at the upper and lower ends of the opening side of the connecting plate.

[0019] As a further description of the above technical solution:

[0020] The flexible bag-supporting pressing strip is made of a flexible rubber strip with a hollow interior.

[0021] The present utility model has the following beneficial effects:

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an adjustable bag-holding mechanism for packaging bags, including bag-holding rods 1. Two sets of bag-holding rods 1 are symmetrically arranged front and rear. The left side of each bag-holding rod 1 is connected to a driving device. When the driving device is activated, it can drive the two sets of bag-holding rods 1 to move in opposite directions. A hollow square tube 2 is fixedly connected to the right side of each bag-holding rod 1. A bag-holding rod 3 is slidably connected inside the hollow square tube 2. The hollow square tube 2 slides up and down along the inner wall of the bag-holding rod 3. Limiting grooves 4 are formed on the inner walls of the left and right sides of the bag-holding rod 3. The limiting grooves 4 are provided with... Several groups are linearly and equidistantly distributed from top to bottom. Limiting plates 6 are slidably connected inside the limiting groove 4. The limiting plates 6 are L-shaped. The bottom end of the limiting plates 6 contacts the top end of the hollow square tube 2. After the bag support rod 3 is inserted into the limiting plates 6, the bag support rod 3 cannot continue to move downward. After the limiting plates 6 are inserted, the outer side of the hollow square tube 2 is threaded with a tightening bolt 5. The inner side of the tightening bolt 5 contacts the outer side of the bag support rod 3, fixing the hollow square tube 2 inside the hollow square tube 2, so that the bag support rod 3 cannot be pulled out. The top end of the bag support rod 3 is fixedly connected with a connecting plate 7 that plays a fixed connection role.

[0032] Reference Figure 1 , Figure 3and Figure 4 The connecting plate 7 is in a "C" shape. At the bottom end of the connecting plate 7, a lower bag-supporting pressing strip 8 is fixedly connected. The lower bag-supporting pressing strip 8 is in a V shape, and the tip part of the V shape of the lower bag-supporting pressing strip 8 faces inward. It is made of metal and is a rigid component to ensure clamping the packaging bag. At the top end of the connecting plate 7, a sealing component is fixedly connected. The sealing component is used to press the upper edge of the bag mouth of the packaging bag. The sealing component includes an upper bag-supporting pressing strip 9. The outer side of the upper bag-supporting pressing strip 9 is fixedly connected to the top end of the connecting plate 7. The connecting plate 7 is in a "C" shape. The lower bag-supporting pressing strip 8 and the upper bag-supporting pressing strip 9 are symmetrically arranged up and down at the upper and lower ends of the opening side of the connecting plate 7, so as to double-clamp the opening of the packaging bag. Inside the upper bag-supporting pressing strip 9, a flexible bag-supporting pressing strip 10 is fixedly connected. There are multiple groups of the flexible bag-supporting pressing strips 10, which are linearly and equidistantly distributed inside the upper bag-supporting pressing strip 9. The flexible bag-supporting pressing strip 10 is made of a flexible rubber strip with a hollow interior to ensure the elasticity of the flexible bag-supporting pressing strip 10 and prevent mechanical damage during direct contact.

[0033] Working principle: When it is desired to conveniently adjust the height of the bag-supporting rod 3, first rotate the fastening bolt 5 to loosen the fastening bolt 5, pull out the limiting piece 6, then draw out the bag-supporting rod 3, slide the bag-supporting rod 3 up and down to adjust its position. After adjusting to an appropriate height, insert the limiting piece 6 and then loosen the bag-supporting rod 3. After the bag-supporting rod 3 drops until it contacts the top of the hollow square tube 2 with the limiting piece 6, tighten the fastening bolt 5 to fix the bag-supporting rod 3, so as to quickly adjust the position of the bag-supporting rod 3. When it is necessary to clamp the bag mouth of the packaging bag, start the driving component on the left side of the bag-holding rod 1. The driving component drives the bag-holding rod 1 to move inward. The bag-holding rod 1 drives the bag-supporting rod 3 to move inward through the hollow square tube 2. The bag-supporting rod 3 drives the connecting plate 7 to move inward. The front and rear connecting plates 7 moving inward drive the lower bag-supporting pressing strip 8 and the upper bag-supporting pressing strip 9 to move inward, so as to double-press the bag mouth up and down and prevent the materials in the packaging bag from spilling out.
