Description

Technical Field

[0001] This utility model belongs to the field of I-beam wheel replacement technology, specifically relating to an auxiliary system for replacing I-beam wheels at the nozzle of a forming machine. Background Technology

[0002] During the operation of the guide rollers on the molding machine, the rollers must be replaced whenever the rubber material inside is exhausted. Currently, manual handling and lifting are used for replacement, which has the following drawbacks: 1) The replacement work is very demanding on operators. Due to the lack of convenient replacement tools or a well-designed replacement process, operators endure significant physical exertion over a long period, resulting in low efficiency; 2) During the replacement of the rollers, the direct contact and long-term friction between the rollers and the ground gradually wears out pits, compromising the integrity of the work area; 3) After pits are formed on the ground, the replacement conditions for the rollers are further worsened. Compared to when the ground is intact, the force required to replace the rollers is now 50% more. This vicious cycle not only increases the burden on operators but may also prolong replacement time, affecting the normal operating time of the equipment and negatively impacting production efficiency. Furthermore, if the pits formed by ground wear are not addressed promptly, they may pose other safety hazards such as tripping hazards. Utility Model Content

[0003] This utility model aims to provide an auxiliary system for replacing I-beam rollers at the forming machine, which reduces the workload of replacing I-beam rollers, maintains the integrity of the ground, improves production efficiency, and solves the problems of the current method of manual handling and lifting for replacement, which results in a heavy burden on operators, damages the integrity of the work site, and further worsens the replacement conditions of I-beam rollers.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a forming machine sprue I-beam replacement auxiliary system, including a movable guide groove located in the active area of ​​the forming machine sprue guide I-beam, an I-beam transport assembly that transports the I-beam along the movable guide groove, and an I-beam removal ramp connected to one side of the movable guide groove at the top. The movable guide groove has partitions installed on the left and right side walls and guide rails installed symmetrically on the bottom. The I-beam transport assembly includes a main frame, I-beam support cylinders symmetrically arranged on the main frame, and rollers located at the four corners of the bottom of the main frame. The rollers can move along the guide rails, thereby driving the I-beams arranged on the I-beam support cylinders to move to the installation area located in front of the sprue guide square steel. The I-beam removal ramp is used to transport the replaced I-beams. The horizontal ground on the other side of the movable guide groove away from the I-beam removal ramp is used to push in new I-beams.

[0005] As a preferred embodiment of the above scheme, the I-beam wheel support cylinder is horizontally and longitudinally arranged, and has a central pivot at both ends. The main frame is provided with a through hole for the central pivot to pass through, so that the I-beam wheel support cylinder can be rotatably installed on the main frame. When the I-beam is placed on the I-beam wheel support cylinder, there is a certain degree of flexibility, avoiding collisions caused by rigid connections. The structural design is reasonable.

[0006] More preferably, the I-beam wheel support rollers are four in number and arranged symmetrically in pairs on the left and right. The I-beam wheel support rollers are made of metal material with heat-treated surface, which improves wear resistance and is a reasonable material selection.

[0007] A further preferred embodiment is that the roller is a V-groove roller, and the top of the guide rail is provided with an inverted "V" protrusion that matches the V-groove of the roller, so that the roller can move along the guide rail, ensuring that the main frame moves along the movable guide groove, and ensuring that the I-beam roller will not collide with the side wall of the movable guide groove, which is a reasonable structural design.

[0008] A further preferred embodiment is that an I-beam wheel interceptor plate is installed at the bottom of the I-beam wheel removal ramp, the I-beam wheel interceptor plate being used to intercept the I-beam wheels rolling down the I-beam wheel removal ramp, thus preventing the I-beam wheels from rolling out along the I-beam wheel removal ramp.

[0009] More preferably, the I-beam wheel interceptor plate has an overall equilateral triangular structure. Triangles are stable, and the structure is simple and robust.

[0010] A further preferred embodiment is that the lower end of the guide rail is narrowed and embedded in the movable guide groove for fixation, and an arc-shaped positioning notch is provided at the junction of the lower end of the guide rail and the ground, so as to facilitate the determination of the pre-embedded depth and ensure that the left and right guide rails are aligned and installed.

[0011] The beneficial effects of this utility model are:

[0012] (1) Compared with the current manual handling and lifting replacement, this application sets an active guide groove in the active area of ​​the I-beam wheel of the forming machine. The I-beam wheel transport component moves along the active guide groove through the guide rail, thereby driving the I-beam wheel placed on the I-beam wheel transport component to the installation area in front of the square steel of the I-beam wheel. Then the workers lift the outer end of the I-beam wheel upward and rotate it 35°, and push it inward in a specific direction, so that the I-beam wheel can be successfully installed on the square steel of the I-beam wheel. The workload is easy, the operation is simple and quick, the work efficiency is greatly improved, and the workload of replacing the I-beam wheel is reduced.

[0013] (2) The horizontal ground on the other side of the movable guide groove away from the I-beam wheel removal ramp is used for pushing in new I-beam wheels. On the side of the movable guide groove opposite to the direction of pushing in the I-beam wheel, there is an I-beam wheel removal ramp. In this way, the I-beam wheel to be replaced is pushed in on one side, and the replaced I-beam wheel is moved away on the other side. The paths do not interfere with each other and there will be no conflict. At the same time, the I-beam wheel removal ramp can effectively use the weight of the I-beam wheel to reduce the amount of moving work, saving time and effort.

[0014] (3) The I-beam wheel transport assembly can only move along the front-to-back direction of the movable guide groove and will not swing left or right. This design ensures the stability of the I-beam wheel during operation and meets the movement requirements of the replacement operation in a specific direction.

[0015] In summary, this utility model has the advantages of easy workload, simple and quick operation, significantly improved work efficiency, and reduced workload of replacing I-beams. Attached Figure Description

[0018] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0019] Combination Figure 1 — Figure 2 As shown, a molding machine inlet I-beam wheel replacement auxiliary system consists of an active guide groove 1 located in the active area of ​​the molding machine inlet guide I-beam wheel, an I-beam wheel transport assembly that transports the I-beam wheel 5 along the active guide groove 1, and an I-beam wheel removal ramp 8 whose top is connected to one side of the active guide groove 1.

[0020] The movable guide groove 1 has partitions 11 installed on the left and right side walls, and guide rails 12 installed symmetrically on the bottom.

[0021] The width of the movable guide groove 1 is preferably 500 mm, the length is preferably 1700 mm, and the depth is preferably 60 mm. The length of the partition 11 is preferably 1700 mm, and the height is preferably 60 mm.

[0022] The lower end of the guide rail 12 is narrowed and embedded in the movable guide groove 1 for fixation. An arc-shaped positioning notch 121 is provided at the junction of the lower end of the guide rail 12 and the ground.

[0023] The I-beam wheel transport assembly consists of a main frame 2, I-beam wheel support cylinders 3 symmetrically arranged on the main frame 2, and rollers 4 located at the four corners of the bottom of the main frame 2. The rollers 4 can move along the guide rail 12, thereby driving the I-beam wheels 5 arranged on the I-beam wheel support cylinders 3 to move to the installation area in front of the guide square steel 6.

[0024] The I-beam wheel support cylinder 3 is horizontally and longitudinally arranged, and has a central rotating shaft 31 at both ends. The main frame 2 is provided with a through hole for the central rotating shaft 31 to pass through, so that the I-beam wheel support cylinder 3 can be rotatably installed on the main frame 2.

[0025] The I-beam support rollers 3 are preferably four in number and arranged symmetrically in pairs on the left and right. The I-beam support rollers 3 are made of metal material with heat-treated surface.

[0026] The roller 4 is preferably a V-groove roller, and the top of the guide rail 12 is provided with an inverted "V" protrusion that matches the V-groove of the roller 4, so that the roller 4 can move along the guide rail 12.

[0027] The I-beam wheel removal ramp 8 is used to transport the replaced I-beam wheel 5 away, and the movable guide groove 1 is on the horizontal ground on the other side away from the I-beam wheel removal ramp 8 for the new I-beam wheel 5 to be pushed in.

[0028] A corresponding I-beam wheel removal ramp 8 is installed at the bottom of the I-beam wheel removal ramp 8. The I-beam wheel removal ramp 7 is used to intercept the I-beam wheels 5 that roll down and move away along the I-beam wheel removal ramp 8.

[0029] The H-beam wheel interceptor plate 7 has an overall equilateral triangular structure.

[0030] The operator first moves the removed I-beam wheel 5 along the I-beam wheel removal ramp 8, then pushes it from the horizontal ground onto the I-beam wheel transport assembly. By adjusting the position of the transport assembly, the operator aligns the I-beam wheel 5 with the guide square steel 6. Then, the operator lifts the outer end of the I-beam wheel 5 upwards and rotates it 35°, pushing it inwards in a specific direction to smoothly install the I-beam wheel 5 onto the guide square steel 6. This angle and force, verified in practice, effectively utilizes the relative positional relationship between the tooling and the guide square steel, allowing the I-beam wheel to be installed smoothly with minimal resistance, greatly reducing the operator's physical exertion and improving replacement efficiency.

[0031] The above operating method greatly reduces the physical exertion of operators, simplifies the replacement process, reduces the problem of extended replacement time caused by ground conditions and difficulties in moving the I-beams, effectively improves replacement efficiency, ensures the normal uptime of equipment, and thus improves overall production efficiency.
