Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a liquid nutritional diet aseptic filling equipment. Background Art

[0002] Liquid nutritional diet aseptic filling equipment is a kind of equipment used to fill liquid foods, such as dairy products, beverages, etc., under aseptic conditions to ensure that the products have a long shelf life at room temperature. Its application fields include aseptic filling of dairy products, aseptic filling of beverages, aseptic filling of wines, etc. Consumers are increasingly concerned about health and nutrition. Aseptic filling does not require the addition of preservatives, which is more in line with modern consumption trends. With the increasing demand of consumers for high-quality and long-shelf-life beverages, the demand for aseptic filling equipment has increased accordingly, providing support for improving filling efficiency and product quality.

[0003] In the prior art, in the liquid nutritional diet aseptic filling technology, flat-bottom bottles face more challenges during aseptic filling, especially for the filling of taller bottles. Because aseptic filling requires strict restrictions on the filling time, forcing the operation speed to be fast enough. Under such high-speed operation, due to the poor stability of the bottom support surface of flat-bottom bottles, they are prone to shaking or tilting, which not only reduces the filling accuracy but also causes the bottles to fall, seriously affecting the filling success rate. More seriously, the shaking and falling of the bottles will damage the integrity of the aseptic environment. In aseptic filling, the aseptic state of the production environment is crucial. Once the bottles fall, not only the filled products are contaminated, but also the entire equipment and operation environment are contaminated by microorganisms, thereby affecting the safety and quality of subsequent products, reducing the yield, and seriously leading to the scrapping of the entire batch of products. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a liquid nutritional diet aseptic filling equipment.

[0005] To achieve the above object, the present utility model adopts the following technical solution: A liquid nutritional diet aseptic filling device, including a device main body, wherein a conveying groove is formed on the surface of the device main body, moving grooves are formed on both sides of the inner wall of the conveying groove, a bottom ladder groove is formed at the bottom of the inner wall of the moving groove, an L-shaped arm groove is formed at the top of the inner wall of the moving groove, a pushing cylinder is fixed to the inner wall of the moving groove, a cushion piece is fixed to one end of the pushing cylinder, a thick ladder pushing piece is fixed to one side of the cushion piece, inclined ladder limiting pieces are fixed to both inclined sides of the thick ladder pushing piece, an end moving straight ladder piece is slidably connected to the surface of the inclined ladder limiting piece, a side inclined ladder groove is formed on one inclined surface of the end moving straight ladder piece, the inner wall of the side inclined ladder groove is slidably connected to the surface of the inclined ladder limiting piece, a bottom limiting auxiliary ladder piece is fixed to the bottom of the end moving straight ladder piece, the surface of the bottom limiting auxiliary ladder piece is slidably connected to the inner wall of the bottom ladder groove, an end extending piece is fixed to one end of the end moving straight ladder piece, and a clamping arm is fixed to the top of the end extending piece. In the prior art, in the liquid nutritional diet aseptic filling technology, flat-bottomed bottles face more challenges during aseptic filling, especially for the filling of taller bottles. Because aseptic filling requires strict restrictions on the filling time, forcing the operating speed to be fast enough. Under such high-speed operation, due to the poor stability of the bottom support surface of the flat-bottomed bottle, it is easy to shake or tilt, which not only reduces the filling accuracy but also causes the bottle to fall, seriously affecting the filling success rate. More seriously, the shaking and falling of the bottle will damage the integrity of the aseptic environment. The aseptic state of the production environment is crucial in aseptic filling. Once the bottle falls, not only the filled product is contaminated, but the entire equipment and operating environment are also contaminated by microorganisms, thus affecting the safety and quality of subsequent products, resulting in a decrease in the finished product rate, and in severe cases, even leading to the scrapping of the entire batch of products. To solve such problems, the present utility model adopts the method of installing a clamping arm. When the stability of the bottles in the production batch is poor, the staff starts the pushing cylinder, and the pushing cylinder retracts, causing the cushion piece to pull the thick ladder pushing piece to move towards the end close to the pushing cylinder. Due to the cooperation and limitation between the side inclined ladder groove and the inclined ladder limiting piece, when one end of the thick ladder pushing piece moves, the end moving straight ladder piece is pulled towards the center to gather. Since it is always affected by friction when sliding in the groove of the end moving straight ladder piece, it is easy to cause the component to shift. Therefore, the bottom limiting auxiliary ladder piece and the bottom ladder groove are used to cooperate and limit its shaking to ensure that it slides along the established track in the groove. Thus, when the end moving straight ladder piece gathers, it pulls the end extending piece to gather the clamping arm towards the center of the conveying groove, clamping the bottle to prevent it from falling. At the same time, because this mechanism is driven by a cylinder, it can meet the requirements of quick clamping and leaving, so as to ensure that when the high-efficiency canning equipment is producing, the equipment can quickly fix the pressure, achieving the effect of improving the finished product rate.

[0006] Preferably, a limited straight groove is formed at the bottom of the inner wall of the moving groove. A limiting cylinder is fixed at the bottom of the cushion member. The circumferential surface of the limiting cylinder is slidably connected to the inner wall of the limited straight groove. In the prior art, when the cylinder pushes the cushion member, since the combined bottom surface area of the cushion member and the thick ladder pushing member is relatively large, when sliding in the groove, the relatively large contact area with the inner wall of the groove causes the assembly to be subject to greater friction, making the assembly prone to deviation, resulting in equipment damage and inability to continue use. At the same time, once the output end of the cylinder is skewed, and since the assembly is difficult to observe and the cylinder continues to output, it will cause damage to other components, increasing the possibility of production accidents. To solve such problems, the present utility model adopts the method of installing a limiting cylinder. When the cylinder pushes the cushion member, due to the cooperation of the limiting cylinder and the limited straight groove, the limiting cylinder slides in the limited straight groove, restricting the sliding direction of the assembly, so that the assembly cannot deviate from the established track, preventing the assembly from being damaged, and achieving the effect of improving the service life of the equipment.

[0007] Preferably, a positioning arc groove is formed on one side of the inclined ladder limiting member, and a positioning spring piece is fixed to the inner wall of the side inclined ladder groove. In the prior art, since the driving force output by the cylinder changes greatly in a short time when starting and stopping, this rapid force change will generate a large acceleration at the output end. This sudden and excessive acceleration often causes mechanical components connected to the cylinder, such as clamping devices or moving arms, to move beyond the designed range, that is, the so-called movement interference phenomenon. Movement interference not only affects the filling accuracy but also causes vibration and impact of the equipment. These additional forces pose a threat to the long-term operation stability of the equipment. Especially on a high-speed aseptic filling line, excessive movement interference leads to impacts between mechanical components, causing noise, wear, and even damage to key components. In addition, frequent maintenance and replacement of damaged components increase the maintenance cost, reduce the production efficiency, and also increase the risk of contamination of the aseptic environment, thus affecting product quality and production safety. To solve such problems, the present utility model adopts the method of installing a positioning spring piece. When the assembly moves to the established position, the inner wall of the positioning arc groove of the inclined ladder limiting member is embedded into the positioning spring piece of the side inclined ladder groove, causing the assembly to decelerate, along with an obvious deceleration and sense of jerk, thereby preventing movement interference of the assembly. At the same time, when the inclined ladder limiting member and the positioning spring piece first come into contact, the positioning spring piece is compressed and undergoes elastic deformation, and friction is generated between the positioning spring piece and the surface of the inclined ladder limiting member, causing the inclined ladder limiting member to decelerate in advance, further ensuring the positioning accuracy of the assembly, and achieving the effect of improving the service life of the equipment.

[0008] Preferably, convex elliptical rubber pads are linearly and arrayedly fixed on one side of the clamping arm. Through the toughness and elastic deformation of the convex elliptical rubber pads, the clamping arm can adapt to bottles with more diameters. At the same time, due to the increased friction of the convex elliptical rubber pads, the bottles are less likely to fall forward and backward, improving the yield.

[0009] Preferably, a ladder groove is provided on the front surface of the device main body, which is convenient for staff to place their legs when sitting down, improving the user experience.

[0010] Preferably, a convex guard plate is fixed on the front surface of the device main body to prevent the staff from getting too close to the working area and improve production safety.

[0011] Preferably, an observation window is provided on the front surface of the device main body, which is convenient for staff to observe the production situation of the working steps and improve the user experience.

[0012] Beneficial effects:

[0013] 1. In the prior art, in the aseptic filling technology of liquid nutritional diets, flat-bottomed bottles face more challenges during aseptic filling, especially for the filling of taller bottles. Since aseptic filling requires strict restrictions on the filling time, the operating speed must be fast enough. Under such high-speed operation, due to the poor stability of the bottom support surface of flat-bottomed bottles, they are prone to shaking or tilting, which not only reduces the filling accuracy but also causes the bottles to tip over, seriously affecting the filling success rate. More seriously, the shaking and tipping of the bottles will damage the integrity of the aseptic environment. In aseptic filling, the aseptic state of the production environment is crucial. Once the bottle tips over, not only the filled product is contaminated, but the entire equipment and operating environment are also contaminated by microorganisms, thus affecting the safety and quality of subsequent products, resulting in a decrease in the finished product rate and even scrapping of the entire batch of products in severe cases. To address such problems, the present utility model solves them by installing clamping arms. When the stability of the bottles in a production batch is poor, the staff activates the pushing cylinder, and the pushing cylinder retracts, causing the cushioning piece to pull the thick ladder pushing piece towards the end close to the pushing cylinder. Due to the cooperation and limitation between the side-inclined ladder groove and the inclined ladder limiting piece, when one end of the thick ladder pushing piece moves, the end-moving straight ladder piece is pulled towards the center to gather. Since it is always affected by friction when sliding in the end-moving straight ladder piece groove, it is easy to cause component deviation. Therefore, the bottom limiting auxiliary ladder piece and the bottom ladder groove are used to cooperate and limit its shaking, ensuring that it slides along the established track in the groove. Thus, when the end-moving straight ladder piece gathers, it pulls the end extension piece to gather the clamping arms towards the center of the conveying groove, clamping the bottle to prevent it from tipping over. At the same time, since this mechanism is driven by a cylinder, it can meet the requirements of quick clamping and leaving, thereby ensuring that when the high-efficiency canning equipment is producing, the equipment can quickly increase the pressure to fix, achieving the effect of improving the finished product rate.

[0014] 2. In the prior art, when the cylinder pushes the cushioning part, due to the relatively large combined bottom area of the cushioning part and the thick ladder pushing part, when sliding in the groove, the relatively large contact area with the inner wall of the groove causes the assembly to be subject to greater frictional force, making the assembly prone to deviation, resulting in equipment damage and inability to continue use. At the same time, once the output end of the cylinder is skewed, and since the assembly is difficult to observe and the cylinder continues to output, it will cause damage to other components, increasing the possibility of production accidents. To address such problems, the present utility model adopts the method of installing a limiting cylinder to achieve that when the cylinder pushes the cushioning part, due to the cooperation of the limiting cylinder and the straight limiting groove, the limiting cylinder slides in the straight limiting groove, restricting the sliding direction of the assembly, preventing the assembly from deviating from the established track, preventing the assembly from being damaged, and achieving the effect of improving the service life of the equipment.

[0015] 3. In the prior art, since the driving force output by the cylinder changes significantly in a short time when starting and stopping, this rapid force change will generate a large acceleration at the output end. This sudden and excessive acceleration often causes mechanical components connected to the cylinder, such as clamping devices or moving arms, to move beyond the designed range, namely the so-called movement interference phenomenon. Movement interference not only affects the filling accuracy but also causes vibration and impact of the equipment. These additional forces pose a threat to the long-term operation stability of the equipment. Especially on high-speed aseptic filling lines, excessive movement interference leads to impacts between mechanical components, causing noise, wear, and even damage to key components. In addition, frequent maintenance and replacement of damaged components increase the maintenance cost, reduce production efficiency, and also increase the risk of contamination of the aseptic environment, thus affecting product quality and production safety. To address such problems, the present utility model adopts the method of installing a positioning spring piece to achieve that when the assembly moves to the established position, the positioning spring piece on the inner wall of the positioning arc groove of the inclined ladder limiting part is embedded in the inclined side ladder groove, causing the assembly to decelerate, accompanied by an obvious deceleration and sense of jerk, thereby preventing movement interference of the assembly. At the same time, when the inclined ladder limiting part and the positioning spring piece first come into contact, the positioning spring piece is compressed and undergoes elastic deformation, generating friction between the positioning spring piece and the surface of the inclined ladder limiting part, causing the inclined ladder limiting part to decelerate in advance, further ensuring the positioning accuracy of the assembly and achieving the effect of improving the service life of the equipment.

However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0027] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific embodiment:

[0029] Refer to Figure 1-8A liquid nutritional meal aseptic filling device comprises a device body 1, a conveying groove 101 is provided on the surface of the device body 1, moving grooves 2 are provided on both sides of the inner wall of the conveying groove 101, a bottom ladder groove 202 is provided at the bottom of the inner wall of the moving groove 2, an L-shaped arm groove 201 is provided at the top of the inner wall of the moving groove 2, a pushing cylinder 203 is fixed to the inner wall of the moving groove 2, a cushion 204 is fixed to one end of the pushing cylinder 203, a thick ladder pusher 205 is fixed to one side of the cushion 204, inclined ladder limiting members 206 are fixed to the oblique edges of both sides of the thick ladder pusher 205, an end moving straight ladder member 207 is slidably connected to the surface of the inclined ladder limiting member 206, a side inclined ladder groove 208 is provided on the inclined surface of one side of the end moving straight ladder member 207, and the inner wall of the side inclined ladder groove 208 is connected to the surface of the inclined ladder limiting member 206 The bottom of the end moving straight ladder member 207 is fixed with a bottom limit auxiliary ladder member 3, and the surface of the bottom limit auxiliary ladder member 3 is slidably connected with the inner wall of the bottom ladder groove 202. An end extension member 209 is fixed to one end of the end moving straight ladder member 207, and a clamping arm 2010 is fixed to the top of the end extension member 209. In the aseptic filling technology of liquid nutritional meals, flat-bottom bottles face more challenges in the aseptic filling process, especially the filling of higher bottles, because aseptic filling requires strict restrictions on the filling time, forcing the operation speed to be fast enough. Under such high-speed operation, the flat-bottom bottle is prone to shaking or tilting due to the poor stability of the bottom support surface, which not only reduces the accuracy of filling, but also causes the bottle to tip over, seriously affecting the success rate of filling. What is more serious is that the bottle The shaking and tipping of the bottle will destroy the integrity of the aseptic environment. The aseptic state of the production environment is crucial in aseptic filling. Once the bottle tips over, not only the filled product is contaminated, but the entire equipment and operating environment are also contaminated by microorganisms, which in turn affects the safety and quality of subsequent products, resulting in a decrease in the yield rate. In severe cases, it also leads to the scrapping of the entire batch of products. The solution is to install the clamp arm 2010. When the stability of the bottles in the production batch is poor, the staff starts the push cylinder 203, and the push cylinder 203 retracts, so that the cushion member 204 pulls the thick ladder push member 205 to move toward one end of the push cylinder 203. Due to the matching and restriction of the side inclined ladder groove 208 and the inclined ladder limiter 206, the thick ladder When one end of the push piece 205 moves, the end-moving straight ladder piece 207 is pulled to gather toward the center. Since it is always affected by friction when sliding in the groove of the end-moving straight ladder piece 207, it is easy to cause the component to shift. Therefore, the shaking is limited by the coordination of the bottom limit auxiliary ladder piece 3 and the bottom ladder groove 202 to ensure that it slides along the predetermined track in the groove. As a result, when the end-moving straight ladder piece 207 gathers, the end extension piece 209 is pulled to gather the clamping arm 2010 to the center of the conveying groove 101 to clamp the bottle to prevent it from tipping over. At the same time, since the mechanism is driven by the cylinder, it can ensure its rapid clamping and leaving requirements, thereby ensuring that during the production of high-efficiency canning equipment, the equipment can quickly increase the pressure fixation to achieve the effect of improving the yield rate.On one side of the clamping arm 2010, a convex elliptical rubber pad 4 is fixedly arranged in a linear array. Through the toughness and elastic deformation of the convex elliptical rubber pad 4, the clamping arm 2010 can adapt to bottles with more diameters. At the same time, due to the increased friction of the convex elliptical rubber pad 4, the bottle is less likely to fall forward and backward, improving the finished product rate. A ladder-shaped groove 5 is formed on the front surface of the equipment main body 1, which is convenient for the staff to place their legs when sitting down, improving the user experience. A convex guard plate 501 is fixed on the front surface of the equipment main body 1 to prevent the staff from contacting the working area too closely, improving production safety. An observation window 502 is arranged on the front surface of the equipment main body 1, which is convenient for the staff to observe the production situation of the working steps, improving the user experience.

[0030] A limited straight groove 301 is provided at the bottom of the inner wall of the movable groove 2. A limiting cylinder 302 is fixed at the bottom of the cushioning member 204. The circumferential surface of the limiting cylinder 302 is slidably connected to the inner wall of the limited straight groove 301. When the cylinder pushes the cushioning member 204, since the combined bottom surface area of the cushioning member 204 and the thick ladder pushing member 205 is large, when sliding in the groove, the large contact area with the inner wall of the groove causes the assembly to be subjected to greater frictional force, making the assembly prone to deviation, resulting in equipment damage and inability to continue use. At the same time, once the output end of the cylinder is skewed, and since the assembly is difficult to observe and the cylinder continues to output, it will cause damage to other components, increasing the possibility of production accidents. This is solved by installing the limiting cylinder 302. When the cylinder pushes the cushioning member 204, due to the cooperation of the limiting cylinder 302 and the limited straight groove 301, the limiting cylinder 302 slides in the limited straight groove 301, restricting the sliding direction of the assembly, so that the assembly cannot deviate from the established track, preventing the assembly from being damaged, and achieving the effect of improving the service life of the equipment. A positioning arc groove 304 is provided on one side of the inclined ladder limiting member 206, and a positioning spring piece 303 is fixed on the inner wall of the side inclined ladder groove 208. Since the driving force output by the cylinder changes greatly in a short time when starting and stopping, this rapid force change will generate a large acceleration at the output end. This sudden and excessive acceleration often causes mechanical components connected to the cylinder, such as clamping devices or moving arms, to move beyond the designed range, that is, the so-called movement interference phenomenon. Movement interference not only affects the filling accuracy but also causes vibration and impact of the equipment. These additional forces pose a threat to the long-term operation stability of the equipment. Especially on high-speed aseptic filling lines, excessive movement interference leads to impacts between mechanical components, causing noise, wear, and even damage to key components. In addition, frequent maintenance and replacement of damaged components increase the maintenance cost, reduce the production efficiency, and also increase the risk of contamination of the aseptic environment, thus affecting product quality and production safety. This is solved by installing the positioning spring piece 303. When the assembly moves to the established position, the inner wall of the positioning arc groove 304 of the inclined ladder limiting member 206 is embedded into the positioning spring piece 303 of the side inclined ladder groove 208, causing the assembly to decelerate, accompanied by an obvious deceleration and sense of jerk, thereby preventing movement interference of the assembly. At the same time, when the inclined ladder limiting member 206 and the positioning spring piece 303 first come into contact, the positioning spring piece 303 is compressed and undergoes elastic deformation, and friction is generated between the positioning spring piece 303 and the surface of the inclined ladder limiting member 206, causing the inclined ladder limiting member 206 to decelerate in advance, further ensuring the positioning accuracy of the assembly, and achieving the effect of improving the service life of the equipment.

[0031] Working principle of the utility model: When the stability of the bottles in a production batch is poor, the staff activates the pushing cylinder 203, and the pushing cylinder 203 retracts, causing the cushioning piece 204 to pull the thick ladder pushing piece 205 to move towards the end close to the pushing cylinder 203. Due to the cooperation and limitation between the side inclined ladder groove 208 and the inclined ladder limiting piece 206, when one end of the thick ladder pushing piece 205 moves, the end moving straight ladder piece 207 is pulled towards the center to gather. Since it is always affected by friction when sliding in the groove of the end moving straight ladder piece 207, it is easy to cause the assembly to shift. Therefore, the bottom limiting auxiliary ladder piece 3 and the bottom ladder groove 202 cooperate to limit its shaking and ensure that it slides along the established track in the groove. Thus, when the end moving straight ladder piece 207 gathers, it pulls the end extension piece 209 to gather the clamping arm 2010 towards the center of the conveying groove 101, clamps the bottle, and prevents it from tipping over. At the same time, since this mechanism is driven by a cylinder, it can meet the requirements of quick clamping and leaving, so as to ensure that when the high-efficiency canning equipment is in production, the equipment can quickly perform pressure fixation.
