Description

Technical Field

[0001] The utility model relates to the technical field of safety protection devices, in particular to a safety protection device for a manual tread feeding rack. Background Art

[0002] During the tire production process, the tread feeder extends and returns in a cycle to achieve the tread bonding on the belt layer bonding drum;

[0003] When the tread feeder is controlled by a solenoid valve, after touching the edge safety switch installed at the front end, the return solenoid valve is energized, and the feeder returns to play a safety protection role. Due to the abnormal extension of the automatic control, the operator was squeezed, and then all were changed to manual rotary valve control;

[0004] After changing to hand-operated valve control, there is no electrical control device, and the safety protection loses its function. Once the hand-operated valve is touched by mistake, if the operator is performing the laminating step at this time, the feeder rack will extend into the machine, which will cause great safety hazards and easily cause personal injury accidents.

[0005] Therefore, in view of the above problems, a manual tread feeding rack safety protection device is now designed to better meet the actual use needs. Utility Model Content

[0008] Preferably, the movable frame is rotatably connected to the fixed frame, and a pressure roller is also connected to the movable frame via a bearing. Through the above structure, pressure can be provided when the tread is bonded to ensure the bonding effect.

[0009] Preferably, the movable frame is rotationally connected to the output end of the first cylinder, and the first cylinder is rotationally connected to the fixed frame. Through the above structure, a basic force can be provided for the rotation of the movable frame.

[0010] Preferably, the width of the mounting frame is greater than the width of the pressure roller, and the mounting frame is a "U"-shaped structure. By limiting the size of the mounting frame, the normal rotation of the pressure roller can be ensured.

[0011] Preferably, the protective frame and the mounting frame are slidably connected, and a cross bar is fixed on the protective frame, and the cross bar contacts the mounting frame to achieve positioning. Through the action of the cross bar, the extreme position of the protective frame can be positioned to ensure the normal operation of the device.

[0012] Preferably, the protective frame is also connected to a roller by a bearing, and a positioning plate is fixed to the protective frame, and the positioning plate and the mounting frame are slidably connected. Through the above structure, a basic guarantee can be provided for the mobile positioning of the protective frame.

[0013] Preferably, one end of a spring is fixed on the protective frame, and the other end of the spring is fixed in the mounting frame, so that the spring can provide a basic force for the automatic reset of the protective frame.

[0014] Preferably, a limit rod is fixed to the output end of the second cylinder, and the limit rod is slidably connected to the mounting frame, and the limit rod contacts the positioning plate to achieve a limiting effect. Through the above structure, the position of the limit rod can be adjusted, thereby providing a basic guarantee for the positioning and unlocking of the protective frame, thereby ensuring the normal operation of the device.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the manual tread feeder safety protection device adopts a dual positioning unlocking mechanism, which can realize one-time positioning of the device when the tread feeder moves forward to feed, making it convenient for workers to perform tread laminating operations. After the laminating is completed, the limiting mechanism can be released to enable the device to continue to move for feeding operations, greatly improving the safety of the device and effectively avoiding accidents in which the device squeezes the operator. The specific contents are as follows:

[0016] The manual tread feeder safety protection device is provided with a limit rod. When the device is in use, a primary positioning protection function can be achieved through the functions of the mounting frame, the protection frame, the roller shaft, the positioning plate and the limit rod, and a secondary positioning function can be achieved in conjunction with the second cylinder and the cross bar to ensure the normal operation of the device.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 The utility model provides a technical solution: a manual tread feeder safety protection device, comprising a feeder body 1, a fixed frame 2 is fixed to the feeder body 1 by bolts, a movable frame 3 is connected to the fixed frame 2, the movable frame 3 and the fixed frame 2 are connected by a first cylinder 4, a mounting frame 5 is fixed to the right side of the fixed frame 2, a protective frame 6 is connected to the mounting frame 5, a bracket 8 is symmetrically fixed to the lower side of the mounting frame 5, and a second cylinder 9 is fixed to the bracket 8.

[0024] The protection frame 6 is slidably connected to the mounting frame 5, and a cross bar 601 is fixed on the protection frame 6, and the cross bar 601 contacts the mounting frame 5 to achieve a positioning effect; a roller 602 is also bearing-connected to the protection frame 6, and a positioning plate 603 is also fixed on the protection frame 6, and the positioning plate 603 is slidably connected to the mounting frame 5; a limiting rod 901 is fixed to the output end of the second cylinder 9, and the limiting rod 901 is slidably connected to the mounting frame 5, and the limiting rod 901 contacts the positioning plate 603 to achieve a limiting effect;

[0025] When using the manual tread feeder safety device, Figure 1-Figure 4 As shown, when the feed rack body 1 drives the fabric to extend and cooperate with the belt drum, the roller 602 first contacts the belt drum, so that the protection frame 6 is forced to slide in the mounting frame 5, and then drives the positioning plate 603 to move until the positioning plate 603 contacts the limit rod 901 to achieve positioning. At this time, the feed rack body 1 stops extending, thereby achieving one-time positioning, which is convenient for the staff to fit the tread with the belt drum, and can effectively avoid the device from causing pinching injuries to the staff, ensuring the safe use of the device;

[0026] The movable frame 3 is rotatably connected to the fixed frame 2, and a pressure roller 301 is also connected to the movable frame 3 by a bearing; the movable frame 3 is rotatably connected to the output end of the first cylinder 4, and the first cylinder 4 is rotatably connected to the fixed frame 2; the width of the mounting frame 5 is greater than the width of the pressure roller 301, and the mounting frame 5 is a "U"-shaped structure; one end of a spring 7 is also fixed to the protective frame 6, and the other end of the spring 7 is fixed in the mounting frame 5;

[0027] After the bonding is completed, Figure 1-Figure 4 As shown, the limiting rod 901 is driven to move by controlling the contraction of the second cylinder 9. When the limiting rod 901 is separated from the positioning plate 603, the limiting effect is released. At this time, the positioning plate 603 is started again to feed materials to ensure the normal operation of the device. During feeding, the angle of the movable frame 3 is adjusted by controlling the first cylinder 4 to make the pressure roller 301 rotate and contact the tread to generate pressure, which is convenient for processing the tread and the belt drum and ensures the processing quality. After the processing is completed, the feeding frame body 1 returns to the origin. At this time, under the action of the spring 7, the protective frame 6 can be automatically reset to facilitate the next cycle of processing. This is the working principle of the manual tread feeding rack safety protection device.
