Description

Technical Field

[0001] This utility model relates to the field of woven bag technology, specifically to a tube material leveling device for woven bag production. Background Technology

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. They are typically made from various chemical plastic materials such as polyethylene and polypropylene. Weave density refers to the number of warp and weft yarns within a 100mm x 100mm woven fabric.

[0003] In the production process of woven bags, the raw materials rolled on the rollers need to be unwound and flattened to avoid affecting the processing quality of the woven bags. However, traditional pressure roller equipment is not convenient to adjust the pressure rollers according to raw materials with different thicknesses and weaving densities. Flattening woven bag raw materials with different thicknesses and weaving densities requires changing the pressure roller set, which reduces production efficiency, increases production costs, and brings inconvenience to users.

[0004] Therefore, it needs to be modified by setting an adjustable pressure roller group, which allows for easy adjustment of the included angle between each pressure roller as needed, so as to adjust the tension according to the weaving density. At the same time, it can tightly compress and flatten weaving materials of different thicknesses, improve production efficiency, and make it convenient for users. Utility Model Content

It solves the problems of traditional pressure roller equipment, which is inconvenient for adjusting the rollers according to different thicknesses and weaving densities, requires changing the entire pressure roller set to level woven bag materials of varying thicknesses and weaving densities, reduces production efficiency, increases production costs, and causes inconvenience to users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tube material leveling device for woven bag production, comprising a base plate, a back plate fixedly connected to the rear side of the top of the base plate, and horizontal plates fixedly connected to the left and right sides of the top of the back plate. The horizontal plates have through-hole circular grooves on their front and rear sides, and a movable roller mechanism is slidably connected inside the grooves. Electric telescopic rods located below the movable roller mechanisms are fixedly connected to the front and rear sides of the left and right sides of the top of the base plate. The output end of the electric telescopic rod is rotatably connected to a lifting roller that cooperates with the movable roller mechanism via a bracket. Hinge seats located between two movable roller mechanisms are slidably connected to the left and right sides of the front of the back plate, and a leveling roller assembly mechanism is hinged to the inner side of the two hinge seats. A leveling platform located below the leveling roller assembly mechanism is fixedly connected to the lower part of the front of the back plate, and the surface of the leveling platform is provided with a smooth coating.

[0007] In a preferred embodiment of this utility model, the movable roller mechanism includes a guide rod slidably connected inside the circular groove. A baffle is fixedly connected to the top of the guide rod, and the bottom of the baffle is in contact with the top of the horizontal plate. A lifting frame is fixedly connected to the bottom of the guide rod. An electric roller is rotatably connected inside the lifting frame. A first compression spring is sleeved on the surface of the guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model places the raw material roller on the right side of the device, allowing it to rotate on the rack. The end of the raw material is then inserted under the right-side moving roller mechanism, the leveling roller assembly, and the left-side moving roller mechanism. Since the leveling roller assembly is hinged between two sliding hinge seats, the front end can be pulled up for easy insertion. After insertion, the leveling roller assembly is lowered, and its gravity presses the raw material firmly onto the surface of the leveling plate. Then, an electric telescopic rod is activated to raise the lifting roller, ensuring the raw material surface is tightly fitted with the moving roller mechanism and the lifting roller, creating an angle between the two ends of the raw material and the leveling roller assembly. The height of the lifting roller can be adjusted according to the weaving density of the raw material, creating different angles and generating varying tensions. The electric roller is then activated, moving the raw material to the left. During this movement, the rollers flatten the material, allowing for easy adjustment of the angles between the rollers to regulate tension based on weaving density. This also allows for tight pressing and flattening of woven raw materials of different thicknesses, improving production efficiency and user convenience.

[0014] 2. This utility model, by setting a guide rod, a lifting frame, an electric roller, and a first compression spring in combination, can raise the lifting frame when placing raw materials, opening the gap between the electric roller and the lifting roller to facilitate the placement of raw materials. Then, the pressure applied to the lifting frame by the first compression spring can make the electric roller fit tightly against the surface of the raw materials, improving the flatness of the raw materials. At the same time, the rise of the lifting roller causes the guide rod to move upward, and the first compression spring to contract, so that the raw materials can always be clamped between the lifting roller and the electric roller, further improving the flatness.

[0020] 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.

[0021] like Figures 1 to 4 As shown, the present invention provides a material leveling device for woven bag production, comprising a base plate 1, a back plate 2 fixedly connected to the rear side of the top of the base plate 1, and horizontal plates 3 fixedly connected to the left and right sides of the top of the back plate 2. Horizontal plates 3 have through-hole circular grooves on both the front and rear sides of the horizontal plates 3, and a moving roller mechanism 4 is slidably connected inside the circular grooves. Electric telescopic rods 5 located below the moving roller mechanism 4 are fixedly connected to the front and rear sides of the left and right sides of the top of the base plate 1. The output end of the electric telescopic rod 5 is rotatably connected to a lifting roller 6 that cooperates with the moving roller mechanism 4 via a bracket. Hinge seats 7 located between the two moving roller mechanisms 4 are slidably connected to the left and right sides of the front of the back plate 2, and a leveling roller assembly mechanism 8 is hinged to the inner side of the two hinge seats 7. A leveling platform 9 located below the leveling roller assembly mechanism 8 is fixedly connected to the lower part of the front of the back plate 2, and the surface of the leveling platform 9 is provided with a smooth coating.

[0022] refer to Figure 1 The moving roller mechanism 4 includes a guide rod 10 slidably connected inside the circular groove. A baffle is fixedly connected to the top of the guide rod 10, and the bottom of the baffle is in contact with the top of the horizontal plate 3. A lifting frame 11 is fixedly connected to the bottom of the guide rod 10. An electric roller 12 is rotatably connected inside the lifting frame 11. A first compression spring 13 is sleeved on the surface of the guide rod 10. The top of the first compression spring 13 is fixedly connected to the bottom of the horizontal plate 3, and the bottom of the first compression spring 13 is fixedly connected to the top of the lifting frame 11.

[0023] As a technical optimization of this utility model, by setting the guide rod 10, the lifting frame 11, the electric roller 12 and the first compression spring 13 to work together, the lifting frame 11 can be raised when the raw material is placed, opening the gap between the electric roller 12 and the lifting roller 6 to facilitate the placement of the raw material. Then, the pressure applied by the first compression spring 13 to the lifting frame 11 can make the electric roller 12 fit tightly against the surface of the raw material, improving the flatness of the raw material. At the same time, the lifting roller 6 rises, causing the guide rod 10 to move upward, and the first compression spring 13 contracts, so that the raw material can always be clamped between the lifting roller 6 and the electric roller 12, further improving the flatness.

[0024] refer to Figure 1The leveling roller assembly 8 includes a movable frame 14 hinged between two hinge seats 7, and a number of evenly distributed leveling rollers 15 are rotatably connected inside the movable frame 14.

[0025] As a technical optimization of this utility model, the movable frame 14 and the flattening roller 15 are used in conjunction. The flattening roller 15 is made of metal and can effectively press and flatten the raw material by its own weight. When placing the raw material, the movable frame 14 can be pulled upward to open the gap between the flattening roller 15 and the flattening plate 9, making it easier to put the raw material in. At the same time, the flattening roller 15 can always be in close contact with the surface of raw materials of different thicknesses, improving the flattening effect.

[0026] refer to Figure 1 The flat plate 9 is made of copper. A heating plate 16 is fixedly connected inside the flat plate 9. A temperature controller 17 is installed at the bottom of the flat plate 9. The temperature controller 17 is electrically connected to the heating plate 16.

[0027] As a technical optimization of this utility model, by setting a heating plate 16, the heating plate 16 can be activated to heat the metal flattening plate 9 during the flattening operation, thereby heating the raw material passing through the flattening plate 9, eliminating wrinkles and internal stress, enhancing fiber extensibility, and improving the flattening effect. The temperature controller 17 is set to control the stability of the heating plate 16, keeping it within a reasonable range. For example, when flattening PP material, the temperature should not exceed 160°C, and when flattening PE material, it should not exceed 120°C, to avoid damage to the raw materials.

[0028] refer to Figure 1 The front of the back plate 2 is fixedly connected to an exhaust hood 18 located above the leveling roller assembly 8. An exhaust fan 19 is fixedly connected to the top of the exhaust hood 18. The input end of the exhaust fan 19 is connected to the top of the exhaust hood 18. The output end of the exhaust fan 19 is threadedly connected to a filter cover 20. An activated carbon filter element is installed inside the filter cover 20.

[0029] As a technical optimization of this utility model, by using the exhaust hood 18, the exhaust fan 19 and the filter cover 20 together, the exhaust fan 19 can be started when the raw material is leveled, so that the exhaust hood 18 generates negative pressure above the leveling plate 9 to absorb the harmful odor gas generated when the raw material is heated and leveled. The gas is then discharged after being filtered by the filter cover 20. The filter cover 20 with threaded connection can be used to facilitate the replacement or cleaning of the filter material.

[0030] refer to Figure 2Both the front and rear sides of the top right side of the base plate 1 are fixedly connected to baffles 21, and both sides of the two baffles 21 are fixedly connected to the opposite side of the baffles 21. Both sides of the top right side of the base plate 1 are slidably connected to the placement rack 23. The inner end of the second compression spring 22 is fixedly connected to the surface of the placement rack 23. The inside of the placement rack 23 is fixedly connected to a bearing.

[0031] As a technical optimization of this utility model, by setting up the baffle 21, the second compression spring 22 and the placement frame 23 in cooperation, the placement frame 23 can be pulled outward to increase the gap of the placement frame 23. The two ends of the raw material roller can be inserted into the placement frame 23 to contact the bearing. After the placement frame 23 is released, it is reset by the pressure of the second compression spring 22. It can fix the raw material roller in place without affecting its rotation, and facilitate replacement, thus improving the convenience of the device.

[0032] The working principle and usage process of this utility model are as follows: The raw material roller is placed on the placement frame 23 on the right side of the device, allowing it to rotate on the frame 23. The head end of the raw material is then inserted under the right-side moving roller mechanism 4, the leveling roller assembly mechanism 8, and the left-side moving roller mechanism 4. Since the leveling roller assembly mechanism 8 is hinged between two sliding hinge seats 7, its front end can be pulled up for easy insertion. After insertion, the leveling roller assembly mechanism 8 is lowered, and its gravity presses the raw material firmly onto the surface of the leveling plate 9. Then, the electric telescopic rod 5 is activated to lift the lifting roller 6, causing... The surface of the raw material is in close contact with the moving roller mechanism 4 and the lifting roller 6, so that the two ends of the raw material form an angle with the flattening roller group mechanism 8. The height of the lifting roller 6 can be adjusted according to the weaving density of the raw material to form different angles and generate different tensions. Then, the electric roller 12 is started to move the raw material to the left. During the movement, it is flattened by the roller groups, so as to facilitate the adjustment of the angle between each roller as needed, so as to adjust the tension according to the weaving density. At the same time, it can tightly press and flatten the woven raw materials of different thicknesses, improve production efficiency, and facilitate the use of the user.
