Description

Technical Field

[0001] This utility model relates to the field of opening roller technology, specifically a cylindrical rubber strip opening roller with adjustable opening width. Background Technology

[0002] In many industries such as textiles, dyeing and printing, papermaking, plastics, packaging, and printing, materials are easily affected by factors such as tension during unwinding, conveying, or rewinding, which can lead to wrinkles and shrinkage. This can cause problems with the original width and flatness of the material. The function of the opening roller is to stretch and flatten the material to prevent wrinkles and shrinkage, and ensure that the material enters the subsequent processing stage in a flat state.

[0003] Most existing rubber strip flattening rollers have a fixed diameter and width, making it difficult to flexibly adjust the width of the stretched material. Furthermore, the curved roller expander causes uneven stress on the fabric due to its arc shape. For some ultra-thin and ultra-soft materials, the threaded expander roller is too rigid in its flattening method, not gentle enough, and is prone to damaging the material. Summary of the Invention

[0004] The purpose of this invention is to provide a cylindrical rubber strip spreading roller with adjustable spreading width, in order to solve the problems mentioned in the background art, where the diameter and width of existing rubber strip spreading rollers are mostly fixed, making it difficult to flexibly adjust the width of the stretched material, and the uneven force on the fabric caused by the arc shape of the bending roller spreader.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical rubber strip opening roller with adjustable opening width, including a metal inner roller rod, which is a roller rod-shaped metal rod, and a connecting rod is installed at each end of the metal inner roller rod, and the metal inner roller rod and the connecting rod together constitute the inner rod main structure of the cylindrical rubber strip opening roller;

[0006] The metal inner roller has annular grooves at both ends, and an electric track is laid in the annular grooves of the metal inner roller. A charging slider is slidably connected in the electric track, and the interface end of the charging slider passes through the limiting side plate. The limiting side plate is penetrated by a connecting rod, and one limiting side plate is provided at each end of the metal inner roller.

[0007] The metal inner roller has mounting grooves equidistantly spaced on both sides of its surface, and the mounting grooves are strip-shaped. An adjustment assembly is installed in the mounting groove, and the adjustment assembly includes a silicone strip, a positioning bolt, a limit frame, a magnetic push rod, and an electromagnet generator. The electromagnet generator is installed in the mounting groove and is connected to the energized track by a cable.

[0008] Using the above technical solution, the adjustment component in the mounting slot is driven by an electromagnetic generator, which can realize the adjustment of the opening width, providing a basis for opening operation.

[0009] Preferably, the axis of the inner metal roller is aligned with the axis of the connecting rod, and the diameter of the connecting rod is smaller than the inner diameter of the annular groove on the end face of the inner metal roller.

[0010] By adopting the above technical solution, the alignment of the metal inner roller and the connecting rod shaft ensures smooth operation of the opening roller and reduces vibration and wear.

[0011] Preferably, the limiting side plate is configured with a double-layer structure, and the inner layer of the limiting side plate is penetrated by the charging slider, and an insulating coating is provided at the connection between the charging slider and the limiting side plate.

[0012] The above technical solution uses a double-layer structure on the limiting side plate with an insulating coating to ensure the charging slider can slide normally and conduct electricity while preventing leakage.

[0013] Preferably, the outer layer of the limiting side plate abuts against one end of the silicone strip, and the silicone strip is configured as an arc-shaped sheet structure, and the silicone strip surrounds the inner metal roller.

[0014] Using the above technical solution, the outer layer of the limiting side plate abuts against the arc-shaped sheet-like silicone strip. The silicone strip is arranged around the inner metal roller rod, which can contact the material in a gentle manner, avoid damage, and facilitate the flattening of the material.

[0015] Preferably, two limiting frames are symmetrically arranged on the surface of the silicone strip, and one limiting frame is threadedly connected to two positioning bolts, with the positioning bolts penetrating the silicone strip.

[0016] Using the above technical solution, the silicone strip is connected to the limiting frame through a positioning bolt, ensuring structural stability and enabling precise transmission of adjustment force to achieve accurate control of the silicone strip's position.

[0017] Preferably, a magnetic push rod is installed at the bottom of the limiting frame, and the limiting frame and the magnetic push rod form a T-shaped structure after being connected, and the magnetic push rod is set at the magnetic end of the electromagnet.

[0018] Using the above technical solution, the limiting frame and the magnetic push rod form a T-shaped structure, which can effectively convert magnetic force into displacement of the silicone strip, with fast response speed and high adjustment accuracy.

[0019] Preferably, the electromagnetic generator is provided with a cylinder that is slidably connected to the magnetic push rod, and the cylinder and the magnetic push rod together form a double-layer sliding sleeve structure.

[0020] Using the above technical solution, the cylinder outside the electromagnet generator and the magnetic push rod form a double-layer sliding sleeve structure, which makes the magnetic push rod slide smoothly and ensures the flexibility and stability of the opening width adjustment.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the adjustable opening width cylindrical rubber strip opening roller:

[0022] 1. The inner rod is constructed by the metal inner roller and the connecting rod, with their axes aligned. This ensures the stability of the opening roller during operation, reduces wobbling and wear caused by axis deviation, extends the service life of the equipment, and guarantees the accuracy and consistency of the opening operation. At the same time, the diameter of the connecting rod is smaller than the inner diameter of the annular groove on the end face of the metal inner roller, providing a reasonable space layout for the installation and movement of other components. Furthermore, the limiting side plate adopts a double-layer structure, with the inner layer penetrated by the charging slider and the connection point having an insulating coating. This ensures the normal sliding and conductivity of the charging slider while effectively preventing leakage, thus improving the safety and electrical performance stability of the equipment.

[0023] 2. When adjusting the opening width of the opening roller, a magnetic field is generated by energizing the electromagnetic generator. The magnetic force acts on the magnetic push rod. At this time, the limit frame and the magnetic push rod form a T-shaped structure and interact with the electromagnetic generator, allowing the silicone strip to move flexibly within a large range, thereby achieving a large adjustment of the opening width. The magnetic drive has a fast response speed and high adjustment accuracy, which can quickly and accurately adjust the opening width to the required value, meeting the diverse requirements of different materials and production processes for the opening width.

[0024] 3. The silicone strips are arc-shaped sheets surrounding the inner metal roller. The material has good flexibility and moderate elasticity, and can apply force to the material in a gentle manner during contact, avoiding scratches and damage to the material surface. With multiple silicone strips evenly distributed on both sides of the inner metal roller surface, the material can be uniformly stretched laterally during the adjustment of the width, effectively eliminating wrinkles and shrinkage, and ensuring that the material is flat throughout the entire width direction.

[0032] 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.

[0033] Please see Figures 1-6 This utility model provides a technical solution: a cylindrical rubber strip opening roller with adjustable opening width, including a metal inner roller rod 1, an electric track 2, a charging slider 3, a limiting side plate 4, a connecting rod 5, a mounting groove 6, an adjusting component 7, a silicone strip 701, a positioning bolt 702, a limiting frame 703, a magnetic push rod 704, and an electromagnetic generator 705;

[0034] Among them, the metal inner roller rod 1 is a roller-shaped metal rod, and a connecting rod 5 is installed at each end of the metal inner roller rod 1. The metal inner roller rod 1 and the connecting rod 5 together constitute the inner rod main structure of the cylindrical rubber strip opening roller.

[0035] The inner metal roller 1 has annular grooves at both ends, and an electric track 2 is laid in the annular grooves of the inner metal roller 1. The axis of the inner metal roller 1 is aligned with the axis of the connecting rod 5, and the diameter of the connecting rod 5 is smaller than the inner diameter of the annular groove at the end face of the inner metal roller 1. A charging slider 3 is slidably connected in the electric track 2, and the interface end of the charging slider 3 passes through the limiting side plate 4. The limiting side plate 4 is penetrated by the connecting rod 5, and one limiting side plate 4 is set at each end of the inner metal roller 1. The limiting side plate 4 is set with a double-layer structure, and the inner layer of the limiting side plate 4 is penetrated by the charging slider 3. An insulating coating is provided at the connection between the charging slider 3 and the limiting side plate 4.

[0036] Referring to the attached diagrams in the instruction manual Figures 1-6As shown, connecting rods 5 are installed at both ends of the inner metal roller 1, ensuring alignment between the axis of the inner metal roller 1 and the axis of the connecting rod 5. High-precision measuring tools are used for calibration to ensure operational stability. Welding is used to maintain the connection and prevent loosening during use. Electrically conductive tracks 2 are laid in the annular grooves at both ends of the inner metal roller 1, ensuring their flatness and conductivity. Further, charging sliders 3 are installed within the electrically conductive tracks 2, allowing them to slide flexibly within the tracks. Then, limiting side plates 4 are installed and fitted onto the connecting rods 5, achieving a rotatable connection between the limiting side plates 4 and the connecting rods 5. The interface end of the charging slider 3 penetrates the inner layer of the limiting side plates 4. An insulating coating is applied to the connection between the charging slider 3 and the limiting side plates 4 to prevent leakage. Figures 1-4 As shown, ensure that the limiting side plate 4 is installed at each end of the metal inner roller rod 1. In actual use, regularly check the wear of the power-on track 2 and the charging slider 3. If severe wear is found, replace them in time.

[0037] Mounting grooves 6 are equidistantly provided on both sides of the surface of the inner metal roller 1. The mounting grooves 6 are strip-shaped. An adjustment assembly 7 is installed in the mounting groove 6. The adjustment assembly 7 includes a silicone strip 701, a positioning bolt 702, a limiting frame 703, a magnetic push rod 704, and an electromagnetic generator 705. The electromagnetic generator 705 is installed in the mounting groove 6 and is connected to the energized track 2 by a cable. The outer layer of the limiting side plate 4 abuts against one end of the silicone strip 701. The silicone strip 701 is set as an arc-shaped sheet structure and surrounds the inner metal roller 1. Two limiting frames 703 are symmetrically arranged on the surface of the silicone strip 701, and one limiting frame 703 is threadedly connected to two positioning bolts 702. The positioning bolts 702 penetrate the silicone strip 701. A magnetic push rod 704 is installed at the bottom of the limiting frame 703. The limiting frame 703 and the magnetic push rod 704 form a T-shaped structure after being connected. The magnetic push rod 704 is set at the magnetic end of the electromagnet 705. A cylinder is set outside the electromagnet 705 and slidably connected to the magnetic push rod 704. The cylinder and the magnetic push rod 704 together form a double-layer sliding sleeve structure.

[0038] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the mounting groove 6 is formed around the surface of the inner metal roller 1, as... Figure 3As shown, the electromagnetic generator 705 is installed in the mounting groove 6 and connected to the energized rail 2 with a cable to ensure a firm connection and good conductivity. The silicone strip 701 is wrapped around the inner metal roller 1, with one end abutting against the outer layer of the limiting side plate 4. Two limiting frames 703 are symmetrically installed on the surface of the silicone strip 701. The limiting frames 703 are threadedly connected to the silicone strip 701 with the positioning bolts 702 to ensure a tight connection. A magnetic push rod 704 is installed at the bottom of the limiting frame 703 to form a T-shaped structure with the limiting frame 703. The magnetic push rod 704 is slidably connected to the cylinder outside the electromagnetic generator 705 to form a double-layer sliding sleeve structure.

[0039] In actual use, by controlling the current of the electromagnet 705, the strength of the magnetic field it generates is changed, thereby adjusting the moving distance of the magnetic push rod 704 synchronously. This causes the opening width of the multiple silicone strips 701 to change accordingly when they move synchronously. After being pushed by the magnetic push rod 704, the silicone strip 701 moves outward. At this time, one end of the silicone strip 701 in the outer ring of the limiting side plate 4 gradually slides outward with the pushing distance. Since the silicone strip 701 is made of silicone material and has a certain degree of flexibility, it is easy for the silicone strip 701 to slide in the outer ring of the limiting side plate 4 during the pushing and retraction process.

[0040] Working principle: When using the adjustable opening width cylindrical rubber strip opening roller, the inner rod main structure composed of the metal inner roller rod 1 and the connecting rod 5 serves as support. The alignment of the axis of the metal inner roller rod 1 with the axis of the connecting rod 5 ensures stability during operation. The power supply component consists of the energized track 2 and the charging slider 3 in the annular grooves at both ends of the metal inner roller rod 1. When the equipment is powered on, the charging slider 3 allows current to flow to the energized track 2. The charging slider 3 is stably installed in the limiting side plate 4. The connecting rod 5 in the limiting side plate 4 drives the metal inner roller rod 1 to rotate, thereby making the energized track 2 and the charging slider 3 rotate. Current is transferred between the energized track 2 and the charging slider 3 through metal conductivity.

[0041] The current is transmitted through the energized track 2 and then through the cable to the electromagnetic generator 705 installed in the mounting groove 6, which generates a magnetic field. When the magnetic field strength of the electromagnetic generator 705 changes, the magnetic push rod 704 slides along the cylinder under the action of the magnetic force. Since the limiting frame 703 is connected to the magnetic push rod 704, the limiting frame 703 drives the silicone strip 701 to move along the mounting groove 6 of the inner metal roller 1. As multiple silicone strips 701 move synchronously, the overall outward expansion degree is changed, thereby realizing the adjustment of the opening width. During the operation of the opening roller, the material comes into contact with the silicone strip 701. The silicone strip 701 rotates with the rotation of the opening roller, and the friction between it and the material drives the material to move. During the opening width adjustment process, the position of the silicone strip 701 changes, generating a lateral tensile force on the material, gradually flattening the material, so that the material passes through the opening roller in a flat state and enters the subsequent processing process, which increases the overall practicality.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
