Description

TECHNICAL FIELD

[0001] The utility model belongs to the tobacco machinery auxiliary tool technical field, concretely relates to a special tightening and loosening tool for the fastening screw of photoelectric tube in tobacco industry. BACKGROUND

[0002] In today's cigarette factory silk workshop, the feeding machine as the key equipment, the accurate control of material flow is very important. And photoelectric tube plays an indispensable role in this process, its accurate detection and feedback function provides important guarantee for the stability and quality of production. However, in the actual production environment, the metal protective cover around the photoelectric tube brings a series of problems to its maintenance and fixation. The original intention of these metal protective covers is to protect the photoelectric tube from interference and damage from external factors, but due to its almost equal length with the photoelectric tube in size, and the width is extremely narrow, which leads to the extremely limited operation space. Especially the fixing screw of photoelectric tube is placed in the special position of the head, which further aggravates the complexity of operation. Because of the narrow space of the head, ordinary wrench can not enter, its shape and size can not adapt to this special structure requirement. This makes the operator have to rely on manual way when tightening the fixing screw. However, manual tightening has many obvious defects and deficiencies. First of all, the force of manual tightening is difficult to apply uniformly, which leads to the inconsistency of the tightening degree of the screw. Sometimes it may be too tight, causing damage to the screw or related parts; sometimes it may be too loose, which cannot provide enough fixing force, thereby affecting the stability and accuracy of the photoelectric tube. Secondly, the efficiency of manual operation is extremely low, in the background of large-scale production, this inefficient operation mode seriously restricts the production progress. Moreover, due to the individual differences of the operators, the quality of manual tightening is difficult to guarantee, and the tightening is not firm. Once the fixing screw is loose, the detection accuracy of the photoelectric tube will be affected, which leads to the inaccuracy of material flow control, eventually may cause the fluctuation of cigarette product quality, increase the rate of defective products, reduce the production efficiency, increase the production cost. This series of problems not only brings many inconveniences to the production, but also has potential negative effects on the economic benefit and market reputation of the enterprise.

[0022] The technical scheme of the present application will be described in detail below through examples. The following examples are only exemplary and can only be used to explain and illustrate the technical scheme of the present application, but cannot be interpreted as a limitation of the technical scheme of the present application.

[0023] As shown in Figure 1 and Figure 2 , the technical scheme is specially designed for a tightening and loosening tool for a photocell fastening screw in the tobacco industry when the conventional tool cannot be used. First, the head end adopts a sleeve design, and its size and specifications have been accurately calculated and repeatedly tested. Unlike ordinary sleeves, its length and inner diameter are specially adjusted to adapt to the narrow space where the photocell fixing screw is located. At the same time, the material of the sleeve is selected to be a high-strength alloy material with good corrosion resistance, which ensures that it can maintain stable performance for a long time in harsh working environments and is not easy to deform and wear. The L-shaped hand lever at the tail end is not simply designed, and its shape and length fully consider the ergonomics principle and the convenience of operation in a narrow space. The material of the hand lever is selected to be a light and strong synthetic material, which reduces the overall weight while ensuring sufficient strength.

[0024] Specifically, the special tightening and loosening tool for the tobacco industry photocell fastening screw of the present application is composed of a sleeve 1 at the head end and an L-shaped hand lever 2 fixedly connected to the tail end of the sleeve. The sleeve at the head end is made of high-strength titanium alloy, which not only has high hardness and wear resistance, but also has good corrosion resistance. The length of the sleeve is 150 mm, and the inner diameter is 24 mm, which perfectly matches the size of the photocell fixing screw and the space it is in. In other embodiments of the present application, if the photocell fastening screw has other models, the length and inner diameter of the sleeve can be changed as needed without affecting the implementation of the technical scheme of the present application.

[0025] An axial through opening 11 is formed in the side wall of the sleeve 1, with a width of 12 mm, a length of 150 mm, and a front end opening angle of 60°. The opening tail end is close to the L-shaped hand lever and extends downward. The extension is semicircular, and the midpoint of the semicircle coincides with the midpoint of the sleeve tail end. This design allows the sleeve to be inserted into the photocell cable at a specific angle, further wrapping the photocell and fixing screw. The inner cavity of the front end of the sleeve is a regular polygon structure, matching the fixing screw.

[0026] The side wall of the sleeve is provided with a non-through axial side opening 12, with a width of 4 mm and a length of 120 mm. The tail end is semicircular with a diameter of 4 mm. This design avoids the risk of the sleeve touching the photocell side cable during wrapping and positioning the photocell to the fixing screw. The inside of the sleeve is finely polished to ensure a tight and smooth contact with the fixing screw, improving the fastening effect.

[0027] The L-shaped hand lever 2 at the tail end is made of lightweight carbon fiber material, with a shape that conforms to the principles of ergonomics. The grip has a non-slip texture design to increase friction during operation and prevent slipping. The total length of the L-shaped hand lever is 150 mm, with a handle 22 that is 50 mm long and a sleeve connecting rod 21 that is 100 mm long, providing sufficient torque to allow the operator to easily apply force in a small space. In this application, the sleeve connecting rod 21 is composed of an inner plate 211 and an outer plate 212 that fit together, and the upper end of the sleeve connecting rod has the same shape as the outer contour of the sleeve tail end.

[0028] In this application, an extension 213 is provided at the upper end of the inner plate, extending towards the sleeve, and is connected to the groove at the tail end of the sleeve to improve the connection strength between the sleeve and the L-shaped lever.

[0029] In use, the operator first aligns the sleeve opening of the tool head with the photocell and inserts it at a certain angle. The cable is wrapped around the photocell cable interface at the tail end, and then the photocell is wrapped and accurately positioned on the fixing screw. Next, the position of the tool is adjusted to accurately align the sleeve opening with the fixing screw, and the screw is inserted into it. At this time, the operator holds the L-shaped hand lever at the tail end and rotates it clockwise as needed to tighten or counterclockwise to loosen. During operation, due to the close fit of the sleeve with the fixing screw and the reasonable design of the hand lever, the operator can accurately control the size and direction of the force, ensuring that the tightening degree of the screw is just right, neither too tight to damage the screw nor too loose to affect the fixing effect.

[0030] In the application, the unique design that the head sleeve is opened to the tail end is one of the key innovations of the utility model. The size and angle of the opening are carefully calculated and optimized, and the existence of the opening enables the sleeve to wrap the cable at the tail cable interface of the photocell, then push the photocell forward to wrap it, and accurately position it on the fixing screw without disassembling other components around the photocell. Meanwhile, the design of the tool side opening avoids the risk of touching the photocell side cable during the process of wrapping the photocell and positioning it to the fixing screw. This design not only greatly improves the convenience of operation, but also saves the operation time and reduces the damage risk caused by disassembling other components. In addition, the L-shaped hand lever has good stability and transmission performance, can efficiently and accurately transmit the force exerted by the operator on the hand lever to the sleeve, and ensure that the tightening or loosening operation of the screw can be smoothly completed.

[0031] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
