Description

Technical Field

[0001] This utility model belongs to the field of label production technology, and is particularly related to a label paper conveying and storage box. Background Technology

[0002] In the label production process, rolls of label paper raw materials need to be conveyed through multiple processing devices. Some devices, such as printing equipment, use a step-by-step conveyor, while others, such as cutting equipment, use a constant-speed conveyor. Because in step-by-step conveyors, the label paper between two processing devices will fall downwards due to gravity after each conveying cycle, a temporary storage box is usually needed between the step-by-step and constant-speed conveyors to hold the falling label paper. Existing temporary storage boxes have two adjusting plates, allowing manual adjustment of the distance between the two fixed plates to accommodate the width of the conveyed label paper. However, this adjustment usually requires turning screws, and the width adjustment also requires manual measurement, which is labor-intensive and necessitates improvement. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides a label paper conveying storage box that can automatically adjust the distance between two vertical plates via a motor to accommodate the width of the conveyed label paper.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A label paper delivery storage box, comprising:

[0006] A rectangular box has an opening at the top. A pair of vertical plates are slidably installed inside the rectangular box along its length. The bottom of each vertical plate has a threaded hole and a guide hole along the length of the rectangular box.

[0007] The linear mechanism includes a screw, a guide rod, and a motor. The screw has two symmetrically arranged threaded sections with opposite directions of rotation, and the two threaded sections are respectively connected to two threaded holes. The guide rod passes through the guide hole, and its two ends are connected to the two ends of the rectangular box. The two ends of the screw are respectively rotatably connected to the two ends of the rectangular box. One end of the screw is connected to the output shaft of the motor.

[0008] Furthermore, a horizontal plate is provided inside the rectangular box, with both ends of the horizontal plate connected to both ends of the rectangular box. The horizontal plate is located above the screw and guide rod. A transverse through groove matching the cross-sectional shape of the horizontal plate is provided on the vertical plate, and the horizontal plate passes through the transverse through groove.

[0009] Furthermore, vertical slots are provided on the vertical plates, which are located above the horizontal plates. A pressure rod passes through the vertical slots. Springs are provided at both ends of the rectangular box, which are fixed above the horizontal plates. One end of each spring is connected to both ends of the pressure rod.

[0010] Furthermore, connecting blocks are rotatably connected to both ends of the pressure rod, and the bottom of the connecting blocks is connected to the spring.

[0011] Furthermore, the connecting block is rectangular, and both ends of the rectangular box are provided with vertical U-shaped slide rails. The two connecting blocks are slidably disposed in the two U-shaped slide rails respectively.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. It can automatically adjust the distance between the two vertical plates to adapt to the width of the conveyed label paper without manual adjustment. The horizontal plate can block the falling label paper and prevent the label paper from contacting the screw and being contaminated by oil.

[0014] 2. The pressure bar can press down the label paper, increasing the tension of the label paper and preventing the label paper from being too tight, which would affect subsequent conveying. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0022] This application provides a label paper conveying and storage box, such as... Figures 1-5 As shown, it includes a rectangular box 1, a linear mechanism, etc.

[0023] Specifically, the top of the rectangular box 1 has an opening, and a pair of vertical plates 2 are slidably arranged inside the rectangular box 1 along the length direction. The bottom of each vertical plate 2 is provided with a threaded hole 201 and a guide hole 202 along the length direction inside the rectangular box 1. The linear mechanism includes a screw 301, a guide rod 302, and a motor 3. The screw 301 is symmetrically provided with two threaded sections with opposite directions of rotation, and the two threaded sections are respectively connected to the two threaded holes 201. The guide rod 302 passes through the guide hole 202, and the two ends of the guide rod 302 are connected to the two ends of the rectangular box 1. The two ends of the screw 301 are respectively rotatably connected to the two ends of the rectangular box 1. One end of the screw 301 is connected to the output shaft of the motor 3.

[0024] In actual use, the control motor 3 drives the screw 301 to rotate. The screw 301 can then drive a pair of vertical plates 2 to move synchronously in opposite directions through two opposing threaded sections, quickly completing the distance adjustment between the pair of vertical plates 2 to accommodate label paper 8 of the corresponding width.

[0025] For details, please refer to Figure 1 , Figure 2 , Figure 5 The rectangular box 1 contains a horizontal plate 4, with both ends of the horizontal plate 4 connected to both ends of the rectangular box 1. The horizontal plate 4 is positioned above the screw 301 and the guide rod 302. A transverse through groove 203 matching the cross-sectional shape of the horizontal plate 4 is provided on the vertical plate 2, and the horizontal plate 4 passes through the transverse through groove 203. By setting the horizontal plate 4, the falling label paper 8 can be blocked, preventing the label paper 8 from contacting the screw 301 and being contaminated by oil.

[0026] Preferred options, please refer to Figure 2 , Figure 3 , Figure 5 Each vertical plate 2 has a vertical through slot 204 located above the horizontal plate 4. A downward pressure rod 5 passes through the vertical through slot 204. Springs 6 are installed at both ends of the rectangular box 1, fixed above the horizontal plate 4. One end of each spring 6 is connected to both ends of the downward pressure rod 5. When the production equipment that conveys the label paper 8 at a constant speed moves the label paper 8 at a constant speed, the label paper 8 hanging between the two production equipment will move upward. At this time, the downward pressure rod 5 is pulled upward by the label paper 8, and the downward pressure rod 5 is pressed down by the elastic force of the springs 6, which can improve the tension of the label paper 8 and prevent the label paper 8 from affecting subsequent conveying due to low tension.

[0027] For details, please refer to Figure 1 , Figure 3 , Figure 5The pressure rod 5 has connecting blocks 501 rotatably connected to both ends. The bottom of the connecting blocks 501 is connected to the spring 6. The pressure rod 5 can rotate when it is rubbed by the label paper 8, which can reduce the friction force on the label paper 8 caused by the pressure rod 5. More specifically, the connecting blocks 501 are rectangular, and both ends of the rectangular box 1 are provided with vertical U-shaped slide rails 7. The two connecting blocks 501 are slidably disposed in the two U-shaped slide rails 7 respectively, which can prevent the pressure rod 5 from tilting during the lifting and lowering process, thus affecting the downward pressure on the label paper 8.

[0028] The above are only some of the embodiments listed in this application and are not intended to limit this application.
