Description

Technical Field

[0001] The utility model relates to the technical field of rubber wheels, in particular to a rubber wheel forming device for a power pulley used in fishing net hauling. Background Technique

[0002] The fishing power pulley is a machine for pulling and sorting fishing nets, mainly composed of side plates, wheels, dimensions, gear rings, etc. Among them, the wheel, as an important part of the power pulley, pulls the fishing net to retract and release through friction. At present, the wheels are mainly formed by casting aluminum alloy in one step, and are divided into two forms: five-rib and ribless; or casting aluminum alloy plus vulcanized ribless rubber.

[0003] For example, the Chinese authorized patent "Rubber Tire Vulcanization and Shaping Device" with the publication number CN210706165U includes a fixed box. The left side of the fixed box is fixedly communicated with a tire cooling outlet cylinder. The top of the fixed box is fixedly connected with an air pump. The input port of the air pump is communicated with an air inlet pipe, and the outlet port of the air pump is communicated with an air outlet pipe. Inside the fixed box, there are a left rotating gear and a right rotating gear, and the middle parts of the left rotating gear and the right rotating gear are both fixedly connected with rotating shafts, and both rotating shafts are rotatably connected to the inner wall of the fixed box.

[0004] Although the above-mentioned existing technologies can be applied to the forming and processing of rubber wheels, this kind of wheel formed by five-rib one-step casting is prone to casting defects, and is prone to corrosion and other defects after a long time of use, which causes great damage to the fishing net. And the cost of mold making and processing is high; the second type is integrally ribless, and the smooth rubber is vulcanized at one time. The production is simple, but the rubber friction is small, which affects the effect of fishing net retraction and release. Therefore, it does not meet the existing requirements. For this reason, we propose a rubber wheel forming device for a power pulley used in fishing net hauling. Summary of the Invention

[0005] The purpose of the utility model is to provide a rubber wheel forming device for a power pulley used in fishing net hauling, so as to solve the problems of easy casting defects and small surface friction of the formed rubber wheel mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A rubber wheel forming device for a power pulley used in fishing net hauling, including a base. On one side of the upper end surface of the base, there is a mold body, which is composed of an upper mold and a lower mold that are movably installed. On the upper and lower end surfaces of the mold body, there are retaining discs. A flange is installed outside the retaining discs, and the flange is fixed to the mold body by bolts. On the other side of the upper end surface of the base, there is a pressing mechanism. On one side of the upper end surface of the pressing mechanism, there is a fixed support. On one side of the support, there is a vulcanization mold. An adjusting screw is installed on the upper end of the support. The threaded end of the adjusting screw is in threaded cooperation with the support. The lower end of the adjusting screw is connected to the vulcanization mold through a bearing. Inside the vulcanization mold, there is a rubber rib forming groove.

[0007] Preferably, a bushing is installed at the central position inside the mold body. A shaft is inserted through the inside of the bushing and extends outside the mold body. Nuts are provided at one ends of the shaft located outside the mold body.

[0008] Preferably, a spring washer is provided between the bolt and the flange.

[0009] Preferably, a positioning column is fixedly installed at the middle position of the upper end surface of the pressing mechanism.

[0010] Preferably, a support frame is welded and fixed to one side of the rear end of the base. An electric push rod is installed at the lower end of the cross bar of the support frame. A driving seat is installed at the movable end of the electric push rod. A pressing wheel is provided below the driving seat.

[0011] Preferably, the centers of the pressing wheel and the positioning column are on the same vertical line.

[0012] Preferably, a servo motor is installed inside the driving seat, and the output shaft of the servo motor is fixedly connected to the upper end of the pressing wheel.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing a mold body in the present utility model, after the raw rubber is proportionally prepared, it is poured into the mold body. The flange is slowly tightened with bolts until it can be locked to compact the rubber. Then the device is moved to a steaming furnace to heat and vulcanize the rubber. This mechanism can quickly realize the pre - forming of the rubber wheel hub, providing a basic guarantee for subsequent secondary forming. Moreover, the mold body is easy to operate and can effectively improve the forming efficiency of the rubber wheel hub.

[0015] 2. After the rubber wheel hub is formed for the first time in the present utility model, it is taken out from the mold body and placed on the pressing mechanism. By rotating the adjusting screw rod, the rotational motion is converted into a linear motion under the frictional action between its external thread and the bracket, causing the vulcanizing mold to move towards the rubber wheel hub until it presses the rubber wheel hub tightly, forming the ribs at this position. After pressing for a set time, by changing the direction, the ribs at other positions of the rubber wheel hub are formed. This pressing mechanism is used to increase the friction of the wheel hub. On the basis of the original smooth - surface rubber wheel hub, a single - piece rubber rib mold is used for secondary vulcanization to apply rubber ribs, increasing the frictional force for pulling the fishing net.

[0016] 3. The utility model is provided with a rubber wheel hub positioning and adjusting mechanism above the pressing mechanism. The rubber wheel hub can be positioned above the pressing mechanism through the positioning column to avoid position deviation. At the same time, through the electric push rod, the pressing wheel is driven to move downward until the upper end of the rubber wheel hub is fixed. At this time, the forming effect of the vulcanization die on the rubber rib can be improved. The clamping force of the pressing wheel on the rubber wheel hub can be relaxed through the electric push rod, and at the same time, the servo motor inside the driving seat drives the rubber wheel hub to rotate through the pressing wheel, so as to facilitate the processing and forming of the rubber rib at the next position, and the accuracy of the rubber rib distribution can be effectively improved, thereby improving the forming quality of the rubber wheel hub.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Please refer to Figures 1-5, an embodiment provided by the present utility model: a rubber hub forming device for a fishing net hauling power pulley, including a base 1. On one side of the upper end surface of the base 1, a mold body 2 is arranged. The mold body 2 is composed of an upper mold and a lower mold which are movably installed. On the upper and lower end surfaces of the mold body 2, retaining discs 3 are arranged. A flange 4 is installed outside the retaining disc 3, and the flange 4 and the mold body 2 are fixed by bolts 5. On the other side of the upper end surface of the base 1, a pressing mechanism 11 is arranged. On one side of the upper end surface of the pressing mechanism 11, a support 13 is fixedly arranged. On one side of the support 13, a vulcanizing mold 15 is arranged. An adjusting screw 14 is installed at the upper end of the support 13. The threaded end of the adjusting screw 14 is in threaded cooperation with the support 13. The lower end of the adjusting screw 14 is connected to the vulcanizing mold 15 through a bearing. Inside the vulcanizing mold 15, a rubber rib forming groove 20 is arranged. A spring washer 8 is arranged between the bolt 5 and the flange 4.

[0025] After the raw rubber is proportionally prepared, it is poured into the mold body 2. The flange 4 is slowly tightened with the bolt 5 until it can be locked to compact the rubber. Then the device is moved to a steam oven to heat and vulcanize the rubber. This mechanism can quickly realize the pre - forming of the rubber hub, providing a basic guarantee for the subsequent secondary forming. After the rubber hub is pre - formed once, it is taken out from the mold body 2 and placed on the pressing mechanism 11. By rotating the adjusting screw 14, the rotational motion is converted into a linear motion under the frictional action between its external thread and the support 13, causing the vulcanizing mold 15 to move towards the rubber hub until it compresses the rubber hub, forming the rib at this position. After pressing for a set time, by changing the direction, the ribs at other positions of the rubber hub are formed.

[0026] Please refer to Figure 2 , at the central position inside the mold body 2, a bushing 10 is installed. A shaft 6 extending outside the mold body 2 is inserted into the bushing 10. Nuts 7 are arranged at one end of the shaft 6 outside the mold body 2, which is used to improve the pre - forming effect of the rubber hub.

[0027] Please refer to Figure 3 , at the middle position of the upper end surface of the pressing mechanism 11, a positioning column 12 is fixedly installed. On one side of the rear end of the base 1, a support frame 16 is welded and fixed. At the lower end of the cross - bar on the support frame 16, an electric push rod 17 is installed. The movable end of the electric push rod 17 is installed with a driving seat 18. Below the driving seat 18, a pressing wheel 19 is arranged. The centers of the pressing wheel 19 and the positioning column 12 are on the same vertical line. A servo motor is installed inside the driving seat 18, and the output shaft of the servo motor is fixedly connected to the upper end of the pressing wheel 19, which can effectively improve the accuracy of the rubber rib distribution, thereby improving the forming quality of the rubber hub.

[0028] Working principle: When in use, the rubber hub can be positioned above the pressing mechanism 11 through the positioning post 12 to avoid position deviation. At the same time, through the electric push rod 17, the pressing wheel 19 is driven to move downward until it fixes the upper end of the rubber hub. At this time, the forming effect of the vulcanization die 15 on the rubber rib can be improved. The electric push rod 17 can relax the clamping force of the pressing wheel 19 on the rubber hub, and at the same time, the servo motor inside the driving seat 18 is started, and the rubber hub is driven to rotate through the pressing wheel 19, so as to facilitate the processing and forming of the rubber rib at the next position.
