Description

Technical Field

[0001] This utility model relates to the technical field of logistics equipment, and in particular to a telescopic tape machine with a protective mechanism. Background Technology

[0002] In logistics conveying systems, telescopic belt conveyors are the core conveying equipment for loading and unloading vehicles. The protective structures on both sides of the conveyor have a significant impact on the stability of package transmission and the service life of the equipment. Traditional telescopic conveyor side guardrails mostly adopt an integral rigid connection design, such as a compact telescopic belt conveyor with Chinese invention patent publication number CN119976199A. Although it can meet the basic protection requirements, it has the following technical defects in practical applications: (1) Sagging deformation problem: During the extension or retraction of the telescopic conveyor, each section of the machine body is prone to sagging deformation due to its own weight and load. This causes the rigid connection side guardrail to bear additional stress, resulting in structural distortion and connection breakage after long-term use, which seriously affects the reliability of the equipment. (2) Poor maintenance adaptability: The integral guardrail is complicated to disassemble and assemble. When the telescopic conveyor section is replaced or repaired, the side guardrail needs to be completely disassembled, resulting in low maintenance efficiency and high cost. Utility Model Content

Detailed Implementation

[0014] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0015] Reference Figure 1 , Figure 2 As shown, a telescopic tape machine with a protective mechanism includes a tape machine 1 and a protective mechanism 2. The protective mechanism 2 is a pair disposed on both sides of the top surface of the tape machine 1. The tape machine 1 includes a fixed section 11 and a telescopic section 12. The telescopic section 12 is sleeved in the fixed section 11. In this embodiment, the telescopic section 12 is not limited to one, but can be several, and multiple telescopic sections 12 are sequentially sleeved. Further details are omitted here. Reference Figure 1 As shown, fixed support feet 6 are provided on both sides of the first end of the fixed section 11. The fixed support feet 6 are fixed to the ground, and the upper part of the fixed support feet 6 is rotatably connected to the side wall of the fixed section 11. Movable support bases are provided on both sides of the end of the fixed section 11. A lifting drive device 7 is hinged on the movable support base. In this embodiment, the lifting drive device 7 is preferably a hydraulic cylinder. Its telescopic end is hinged to the side wall of the fixed section 11, so that the conveyor belt 1 can be driven to rotate up and down around the fixed support feet 6 by the lifting drive device 7, thereby adjusting the conveying angle of the conveyor belt 1.

[0016] In this embodiment, a telescopic drive device is fixedly installed inside the fixed section 11. The telescopic drive device is preferably a cylinder, and its telescopic end is fixedly connected to the telescopic section 12. The telescopic drive device drives the telescopic section to extend or retract. This structure is existing technology, and will not be described again in this embodiment.

[0017] Reference Figure 2 As shown, further, an upward sliding support mechanism 3 is provided at the upper part of the first end of the telescopic section 12, so that the upward sliding support mechanism 3 slides and engages with the inner wall of the top surface of the fixed section 11. A downward sliding support mechanism 4 is provided at the end of the fixed section 11, and the downward sliding support mechanism 4 of the fixed section 11 slides and engages with the bottom surface of the telescopic section 12. A guide wheel 5 is rotatably provided on the lower side wall of the first end of the telescopic section 12, and guide rails that slide and engage with the guide wheel 5 are provided on both sides of the bottom surface of the inner cavity of the fixed section 11.

[0018] Combination Figure 3 , Figure 4 As shown, specifically, the upper sliding support mechanism 3 includes an upper pulley 31 and a connecting rod 32. The connecting rod 32 is fixedly installed at the upper part of the first end of the telescopic section 12. The two ends of the connecting rod 32 are provided with mounting side plates. The upper pulley 31 is a pair and is rotatably installed on the mounting side plates so that the upper pulley 32 slides in cooperation with the inner wall of the top surface of the fixed section 11.

[0019] The sliding support mechanism 4 includes a pair of sliding wheels 41, which are rotatably mounted on the bottom surface of the end of the fixed section 11 so that the sliding wheels 41 slide in contact with the bottom surface of the telescopic section 12.

[0020] With the above settings, the bottom of the telescopic section 12 is supported by the lower pulley 41, and the stability of the telescopic section 12 is greatly improved by the upper pulley 31 and the guide wheel 5, thus preventing shaking when the telescopic section 12 becomes longer.

[0021] Specifically, in this embodiment, the above-mentioned upper sliding support mechanism 3, lower sliding support mechanism 4, and guide wheel 5 are also used between the multiple telescopic sections 12, thereby improving the stability when the multiple telescopic sections 12 are extended. This will not be repeated here.

[0022] Reference Figure 1 , Figure 5 As shown, more preferably, the protective mechanism 2 includes multiple telescopic tubes 21 that are sequentially connected. The telescopic tubes 21 are fixedly connected to the fixed end 11 and the telescopic section 12, respectively. One of the telescopic tubes 21 is fixedly provided with a fixed mounting seat 23, which is fixedly connected to the side wall of the telescopic section 12. The remaining telescopic tubes 21 are fixedly connected to the telescopic section 12 through an adjustment mechanism 22. When the telescopic section 12 extends, the multiple telescopic tubes 21 extend and retract synchronously with the telescopic section 12, thereby using the telescopic tubes 21 to prevent the packages from falling off the side of the tape machine 1 when the goods are being stored.

[0023] Reference Figure 6 , Figure 7 As shown, the adjustment mechanism 22 includes an adjustment fixing seat 221 and a connecting column 222. The adjustment fixing seat 221 is fixedly installed on the side wall of the telescopic section 12. The upper part of the connecting column 222 is fixedly installed on the telescopic tube 21 by welding. The upper part of the adjustment fixing seat 221 is provided with a limiting groove 223. The lower part of the connecting column 222 is inserted into the limiting groove 223. The side wall of the limiting groove 223 is provided with a strip hole 224. The limiting pin 225 is fixedly connected to the connecting column 222 through the strip hole 224 so that the limiting pin 225 can move up and down in the strip hole 224. This realizes that when the telescopic section 12 extends, it can counteract the deformation of the telescopic tube 21 caused by the sagging of the telescopic section 12, and extend the service life of the telescopic tube 21.

[0024] Furthermore, a limiting mechanism is provided at the rear end of the telescopic tube 21. In this embodiment, the limiting mechanism can be a protrusion, which can be elastically set on the telescopic tube 21. The inner wall of the telescopic tube 21 has a limiting hole that cooperates with the protrusion for stopping. This structure is existing technology and will not be described in detail here. This is to prevent the two telescopic tubes from separating and to ensure the telescopic stability of the telescopic tube.

[0025] Reference Figure 5 , Figure 7 As shown, preferably, in this embodiment, the ends of the telescopic tube 21 located on the fixed section 11 and the telescopic tube 21 located on the last telescopic section 12 are bent outwards, so that a horn-shaped opening is formed between the ends of the telescopic tube 21, thereby ensuring that the package can smoothly enter the tape machine 1 and preventing the package from being blocked by the telescopic tube 21 and unable to continue moving forward. A transition sleeve 24 is provided at the joint between the telescopic tubes 21 to avoid the situation of the package or hand being pinched.

[0026] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They cannot be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit of the main technical solution of this utility model should be covered within the protection scope of this utility model.
