Description

Technical Field

[0001] This utility model relates to the technical field of tape tensioning equipment, specifically a novel tape tensioning device. Background Technology

[0002] In daily industrial production, in order to improve the strength and corrosion resistance of metal substrates, plastic lining machines are usually used to line the surface of metal substrates with high-polymer anti-corrosion materials. Through special processes, the metal and plastic are combined, which combines the mechanical strength of metal and the corrosion resistance of plastic. In plastic lining machines, a tape tensioning device of the same specification is generally used to tension the plastic lining tape, so that the plastic lining tape is tightly attached to the surface of the metal substrate.

[0003] Existing tape tensioning devices are usually fixed inside the plastic-lined frame machine, and the plastic-lined tape is tensioned by pressing the plastic-lined tape with tensioning rollers;

[0004] The nuts of existing tape tensioning devices are welded inside the frame. If the threads are damaged, the frame must be cut to replace them, which involves a lot of modification and damage to the equipment. Therefore, we propose a new type of tape tensioning device. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of tape tensioning device. This new tape tensioning device is a separate unit that can be removed from the frame. Its use is not affected by the material of the frame. By clamping the adjusting nut in the fixed plate, the adjusting nut can be replaced separately, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel tape tensioning device, including a mounting frame;

[0007] Mounting frame: A fixing plate is fixedly connected to its left surface, and an adjusting nut is snapped into the left surface of the fixing plate. A lead screw is threaded into the threaded hole inside the adjusting nut. An adjustable bearing seat is provided at the right end of the lead screw. This new type of tape tensioning device is a separate unit. The entire device can be removed from the frame. Its use is not affected by the material of the frame, and the adjusting nut can be replaced separately.

[0008] Furthermore, the mounting bracket is internally fixedly connected with symmetrically distributed ribs, and the upper and lower surfaces of the bearing seat are provided with rib grooves. The ribs are slidably connected in the rib grooves on the same side to limit the lateral sliding of the bearing seat.

[0009] Furthermore, a clearance opening is provided on the left surface of the bearing housing, and the right end of the lead screw is rotatably connected to the clearance opening so that the rotation of the lead screw does not affect the bearing housing.

[0010] Furthermore, a slot is provided on the left side of the bearing housing, which is connected to the clearance opening to facilitate the installation of the thrust bearing and the fixing nut.

[0011] Furthermore, a thrust bearing is provided on the right side of the outer surface of the lead screw. The thrust bearing is located in the slot and bears part of the axial force.

[0012] Furthermore, a fixing nut is fixedly connected to the right end of the lead screw to prevent the right end of the lead screw from separating from the bearing seat.

[0013] Furthermore, a fixing block is fixedly connected to the left end of the lead screw to facilitate rotation of the lead screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel tape tensioning device has the following advantages:

[0015] This new type of tape tensioning device is a separate unit. The entire device can be removed from the frame and its use is not affected by the material of the frame. The adjusting nut can be replaced separately by snapping it into the fixed plate. Attached Figure Description

[0019] 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.

[0020] Please see Figs. 1-2 This embodiment provides a technical solution: a novel tape tensioning device, including a mounting frame 1;

[0021] Mounting bracket 1: A fixing plate 4 is fixedly connected to its left surface. An adjusting nut 3 is snapped onto the left surface of the fixing plate 4. A lead screw 2 is threaded into the threaded hole inside the adjusting nut 3. A fixing block is fixedly connected to the left end of the lead screw 2. A wrench is inserted into the fixing block, and rotating the wrench causes the fixing block to rotate, which in turn causes the lead screw 2 to rotate. Under the action of the adjusting nut 3, the lead screw 2 moves laterally. An adjustable bearing seat 5 is provided at the right end of the lead screw 2. Ribs 6 are symmetrically distributed vertically and vertically fixedly connected inside the mounting bracket 1. Rib grooves are provided on both the upper and lower surfaces of the bearing seat 5. The ribs 6 are slidably connected to the rib grooves on the same side. An avoidance groove is provided on the left surface of the bearing seat 5. The right end of the lead screw 2 is rotatably connected to the clearance opening. A slot 9 is provided on the left side of the bearing seat 5, which is connected to the clearance opening. A thrust bearing 7 is provided on the right side of the outer surface of the lead screw 2, which is located in the slot 9. A fixing nut 8 is fixedly connected to the right end of the lead screw 2. When the lead screw 2 rotates, it drives the thrust bearing 7 and the fixing nut 8 to rotate (the inner arc surface of the tight ring of the thrust bearing 7 is fixedly connected to the right side of the outer surface of the lead screw 2). The movement of the lead screw 2 drives the bearing seat 5 to move laterally along the direction of the rib 6, thereby adjusting the position of the bearing seat 5 and causing the bearing seat 5 to drive the external tensioning roller to move, thereby tensioning the conveyor belt.

[0022] The working principle of the novel tape tensioning device provided by this utility model is as follows: When using this novel tape tensioning device to tension the tape, the wrench is inserted into the fixing block, and the wrench is rotated to make the fixing block rotate, which drives the lead screw 2 to rotate. Under the action of the adjusting nut 3, the lead screw 2 moves laterally, which at the same time drives the thrust bearing 7 and the fixing nut 8 to rotate (the inner arc surface of the tight ring of the thrust bearing 7 is fixedly connected to the right side of the outer surface of the lead screw 2), which drives the bearing seat 5 to move laterally along the direction of the rib 6, thereby adjusting the position of the bearing seat 5, so that the bearing seat 5 drives the external tensioning roller to move, thereby tensioning the tape.

[0023] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
