Description

Technical Field

[0001] The utility model relates to the technical field of aseptic packaging box preparation, and particularly relates to an unwinding structure for preparing an aseptic packaging box. Background Art

[0002] With the rapid development of the food and medical industries, the demand for aseptic packaging boxes is increasing day by day. Aseptic packaging boxes are mainly used for packaging products such as food and medicine to maintain the aseptic state of the products and prevent contamination. After being manufactured, the aseptic packaging boxes need to be disinfected to ensure the aseptic environment inside the packaging boxes. The existing aseptic packaging boxes are usually disinfected once after being manufactured. However, this disinfection method often fails to effectively reach the dead corners of the packaging boxes, resulting in incomplete disinfection.

[0003] In contrast, disinfecting the aseptic packaging box before it is formed can avoid this problem. Especially for the material of the aseptic packaging box in the unwinding stage, at this time, the material of the aseptic packaging box is in a fully spread state, and it can be disinfected in all directions. Combined with the disinfection after being manufactured, a better disinfection effect can be achieved to ensure the aseptic state of the product.

[0004] However, the disinfection measures for the material are often ignored in the existing unwinding process. The existing unwinding structure mainly focuses on preventing problems such as wrinkles in the aseptic packaging box, and the material is often not disinfected during the unwinding process. This results in the formation of dead corners in the material during the subsequent processing, making it impossible to disinfect efficiently.

[0005] Therefore, it is very necessary to disinfect the material of the aseptic packaging box during the unwinding process. This can not only improve the disinfection efficiency but also ensure the aseptic state of the product, meeting the high requirements of the food and medical industries for aseptic packaging. Content of the Utility Model

[0006] In view of this, the utility model provides an unwinding structure for preparing an aseptic packaging box. The utility model can disinfect the material by contacting it closely, ensuring the scope and quality of disinfection.

[0007] To solve the above technical problems, the present utility model provides an unwinding structure for preparing a sterile packaging box, which includes an unwinding box and a disinfection component. The disinfection component includes a material inlet disinfection lamp, a hollow shaft, and a main disinfection lamp. The two sides of the unwinding box are provided with material inlets. Both the upper and lower sides of the material inlets are fixedly connected with material inlet disinfection lamps. The two material inlet disinfection lamps located at the same material inlet are symmetrically distributed up and down with the middle of the material inlet as the center. The middle part of the unwinding box is rotatably connected with a hollow shaft. The middle part of the hollow shaft is fixedly connected with a main disinfection lamp. The middle part of the hollow shaft is provided with a plurality of light-transmitting grooves arranged in a circular array around the central axis of the main disinfection lamp. One side of the unwinding box is fixedly connected with a disinfection motor. The output shaft of the disinfection motor is fixedly connected with the middle part of one end of the hollow shaft. One side of the unwinding box is fixedly connected with a bracket. One side of the bracket is rotatably connected with an unwinding shaft. One side of the unwinding box is connected with a pull plate through a hinge to directly contact the material at a short distance, ensuring the disinfection range and quality.

[0008] The disinfection component further includes a protective shell. Both the upper and lower sides of the material inlets are fixedly connected with protective shells. The protective shells are hollow cylinders, and the middle parts of the protective shells are provided with a plurality of disinfection grooves; that is, it avoids the direct contact between the material and the material inlet disinfection lamp, reducing friction damage.

[0009] A guiding component is arranged on one side of each material inlet. The guiding component includes a rotating column. Two symmetrically arranged rotating columns are rotatably connected to one side of each material inlet; that is, it optimizes the unwinding path of the material, ensuring the smooth movement of the material.

[0010] The guiding component further includes two symmetrically distributed leveling shafts rotatably connected inside the unwinding box. The topmost part of the leveling shaft is at the same horizontal plane as the midpoint of the material inlet; that is, it keeps the material flat, avoiding damage or wrinkles caused by improper tension.

[0011] Anti-slip grooves are arranged on the outer walls of the leveling shafts in a circular array around the central axis of the adjacent leveling shafts; that is, it increases the contact area between the material and the leveling shafts, improving the friction force.

[0012] An exhaust fan is fixedly connected to the top of the unwinding box; that is, it maintains the air circulation inside the box, preventing the accumulation of heat and moisture, and avoiding material deformation or bacterial growth.

[0013] A protective cover is fixedly connected to the top of the exhaust fan; that is, it protects the exhaust fan from external pollution, ensuring normal operation.

[0014] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0015] 1. The material is placed at the bottom of the hollow shaft inside the unwinding box and fits against the bottom of the hollow shaft. Therefore, the light of the active disinfection lamp will directly contact the material at a short distance through the light-transmitting groove, enhancing the disinfection effect. During this process, the material continuously passing through the active disinfection lamp is disinfected, and all the materials passing through the active disinfection lamp can be disinfected, ensuring the scope and quality of disinfection.

[0016] 2. The light of the active disinfection lamp directly contacts the material at a short distance through the light-transmitting groove, enhancing the disinfection effect. The material inlet disinfection lamp is directly set at the material inlet and contacts the material at a short distance, enabling the material to receive sufficient light. At the same time, compared with laying disinfection lamps extensively inside the unwinding box, this short-distance disinfection can effectively reduce costs. Brief Description of the Drawings

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-4 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.

[0026] Such as Figures 1-4As shown in the figure: This embodiment provides an unwinding structure for preparing a sterile packaging box, which includes an unwinding box 100 and a disinfection component 200. The disinfection component 200 includes a material inlet disinfection lamp 201, a hollow shaft 202, and a main disinfection lamp 203. Material inlets are provided on both sides of the unwinding box 100. Material inlet disinfection lamps 201 are fixedly connected to both the upper and lower sides of the material inlet. The two material inlet disinfection lamps 201 located at the same material inlet are symmetrically distributed up and down with the middle of the material inlet as the center. A hollow shaft 202 is rotatably connected to the middle of the unwinding box 100. A main disinfection lamp 203 is fixedly connected to the middle of the hollow shaft 202. A plurality of light-transmitting grooves are provided in the middle of the hollow shaft 202 and are arranged in an annular array around the central axis of the main disinfection lamp 203. Both the main disinfection lamp 203 and the material inlet disinfection lamp 201 are ultraviolet disinfection lamps. A disinfection motor is fixedly connected to one side of the unwinding box 100. The output shaft of the disinfection motor is fixedly connected to the middle of one end of the hollow shaft 202. A support 101 is fixedly connected to one side of the unwinding box 100. A winding shaft 102 is rotatably connected to one side of the support 101. A pull plate is connected to one side of the unwinding box 100 through a hinge;

[0027] First, the material inlet disinfection lamp 201 is aligned with the material inlet to preliminarily disinfect the material about to enter the unwinding box 100. Then, the material enters the unwinding box 100 through the material inlet. Inside the unwinding box 100, the active disinfection lamp 203 disinfects the material through the light-transmitting groove. Since the active disinfection lamp 203 is located in the middle of the hollow shaft 202, and the material inside the unwinding box 100 will be at the bottom of the hollow shaft 202 and fit with the bottom of the hollow shaft 202, the light of the active disinfection lamp 203 will directly contact the material at a short distance through the light-transmitting groove, enhancing the disinfection effect. At the same time, the disinfection motor drives the hollow shaft 202 to rotate. As the hollow shaft 202 rotates, the material in contact with it will also move accordingly and drive the unwinding shaft 102 to rotate for unwinding. During this process, the material continuously passing through the active disinfection lamp 203 is disinfected, and all the material passing through the active disinfection lamp 203 can be disinfected, ensuring the scope and quality of disinfection. When the material enters and exits the unwinding box 100 through the material inlet, both the upper and lower sides of the material are irradiated by the material inlet disinfection lamp 201, further ensuring the aseptic state of the material when entering and leaving the unwinding box 100. Disinfection is carried out before entry to prevent excessive external bacteria from entering the unwinding box 100 and contaminating the environment inside the box. Disinfection is carried out when leaving the unwinding box 100 to ensure that the material is in a disinfected state before the next processing step. At the same time, the material inlet disinfection lamp 201 is directly set at the material inlet and is in close contact with the material, which can make the material receive sufficient light. At the same time, compared with laying a large number of disinfection lamps in the unwinding box 100, this close-range disinfection can effectively reduce costs while ensuring an effective disinfection effect. By adjusting the unwinding speed, the residence time of the material in the illumination areas of the material inlet disinfection lamp 201 and the active disinfection lamp 203 can be further optimized, thereby improving the disinfection effect. The unwinding box 100 can be opened through the pull plate to optimize the unwinding path of the material.

[0028] The protective shell 204 is as Figure 3 、 4 shown,

[0029] The disinfection assembly 200 further includes a protective shell 204. Protective shells 204 are fixedly connected to both the upper and lower sides of the material inlet. The protective shell 204 is a hollow cylinder. A plurality of disinfection grooves are formed in the middle of the protective shell 204. The protective shell 204 is arranged to coincide with the axis of the adjacent material inlet disinfection lamp 201;

[0030] The protective shell 204 can prevent the material from directly contacting the material inlet disinfection lamp 201 and avoid damage to the material inlet disinfection lamp 201 caused by long-term friction. At the same time, the disinfection grooves of the protective shell 204 allow the disinfection light to pass through, ensuring that the material can still receive sufficient disinfection when entering and leaving the unwinding box 100. The cylindrical shape of the protective shell 204 makes the passage of the material smoother.

[0031] The guiding assembly 300 is asFigure 1 , 2 As shown in Figure 3,

[0032] On one side of the material inlet, a guiding component 300 is provided. The guiding component 300 includes a rotating column 301. On one side of the material inlet, two symmetrically arranged rotating columns 301 are rotatably connected, and the midpoint between the two rotating columns 301 on the same side coincides with the midpoint of the two openings;

[0033] When the material enters or leaves the unwinding box 100, it will be in contact with the adjacent rotating column 301. The unwinding path of the material of the sterile packaging box is optimized by the rotating column 301, thereby improving the unwinding efficiency of the material and the production quality of the sterile packaging box. When the material enters and leaves the unwinding box 100, it can move smoothly along the predetermined path, reducing the distortion and folding of the material, and preventing the material from contacting the disinfection tank of the protective shell 204 and causing unnecessary scraping damage to the material.

[0034] The guiding component 300 is as shown in Figure 3 , 4 shown.

[0035] The guiding component 300 further includes two symmetrically distributed leveling shafts 302 rotatably connected inside the unwinding box 100. The top of the leveling shaft 302 is on the same horizontal plane as the midpoint of the material inlet. One end of each leveling shaft 302 is fixedly connected with a sprocket, and the two sprockets are connected by a chain drive. One side of the unwinding box 100 is fixedly connected with a rotating motor, and the output shaft of the rotating motor is fixedly connected with the middle part of one end of the leveling shaft 302 on one side;

[0036] When the rotating motor is started, the leveling shaft 302 will rotate accordingly, thereby applying a uniform pressure to the material to keep it flat. By controlling the speed of the rotating motor, the rotation speed of the leveling shaft 302 can be adjusted, and then the unwinding speed and tension of the material can be controlled, avoiding material damage or wrinkles caused by too large or too small tension. The chain drive of the sprockets and the chain ensures the synchronous rotation of the leveling shafts 302, thus realizing a smoother and more uniform unwinding process. At the same time, the leveling shaft 302 effectively avoids the phenomenon that the material rubs against the protective shell 204 due to the angle problem when passing through the material inlet and entering the inside of the winding box. Through the leveling shaft 302, the material can be effectively kept flush with the state when entering the winding box.

[0037] The anti-slip grooves 303 are as shown in Figure 4 shown.

[0038] On the outer wall of the leveling shaft 302, a plurality of anti-slip grooves 303 are provided, which are arranged in an annular array around the central axis of the adjacent leveling shaft 302;

[0039] When the material passes through the leveling shaft 302, the anti-slip grooves 303 increase the contact area between the material and the leveling shaft 302, thereby increasing the frictional force, enabling the material to move more stably during unwinding. The annular array setting of the anti-slip grooves 303 ensures uniform stress of the material on the leveling shaft 302. No matter where the material is located, it can obtain sufficient support and frictional force, which helps to eliminate the distortion and folding of the material during unwinding and ensures the flatness of the material.

[0040] The exhaust fan 103 is as Figure 1 、 2 、shown in Figure 3

[0041] The top of the unwinding box 100 is fixedly connected with an exhaust fan 103;

[0042] Through the continuous operation of the exhaust fan 103, the air inside the unwinding box 100 can be continuously discharged, thereby maintaining the air circulation inside the unwinding box 100 and preventing the deformation of the material or the growth of bacteria caused by the accumulation of heat and moisture generated during the material unwinding process.

[0043] The protective cover 104 is as Figure 1 、 2 、shown in Figure 3

[0044] The top of the exhaust fan 103 is fixedly connected with a protective cover 104;

[0045] The protective cover 104 can effectively prevent external dust, impurities and other pollutants from entering the exhaust fan 103, thereby protecting the normal operation of the exhaust fan 103, extending its service life, and protecting the cleanliness inside the winding box.

[0046] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0047] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
