Description

Technical Field

[0001] The invention relates to the technical field of product packaging, in particular to automatic sausage packaging equipment and a packaging method thereof. Background Art

[0002] Sausage is a food that uses very ancient food production and meat preservation technology. Animal meat is minced into strips and then stuffed into casings to make a long cylindrical tube of food. Sausages are made by stuffing the small intestine casings of pigs or sheep (some use large intestine casings) with seasoned meat and drying. After the sausages are made, in order to ensure their taste and quality, they are often transported or stored in vacuum packaging;

[0003] In the process of mass production of sausages, since the outer casing of sausages is mostly sausage casings, which are soft, smooth and easy to be damaged, automated equipment is often used to package sausages, and suction cups are used to transfer and transport sausages before packaging. However, the outer casing of sausages is often accompanied by grease during the production process. When using suction cups, it is necessary to ensure that the suction cups and the surrounding surfaces are clean and oil-free to prevent affecting the adsorption capacity of the suction cups. It is also necessary to properly adjust the adsorption force of the suction cups according to the actual filling size of the sausages and the specifications of the casings to avoid excessive or insufficient suction to adversely affect the enema process. The currently commonly used fixed suction cups and auxiliary handling components have a large working range limitation when dealing with the handling operations before sausage packaging, and it is difficult to clean up the oil in time, which increases the packaging time of the sausage body and the probability of it being polluted or oxidized by the external environment, increases the probability of casing damage or deformation of the sausage body, and reduces the overall packaging efficiency of the sausage and the overall quality of the sausage body after packaging.

DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] The embodiment of the present invention provides an automatic sausage packaging device, which solves the problem that the currently commonly used sausage packaging equipment is difficult to reduce the degree of human involvement, increases the probability of sausages being contaminated due to increased exposure time in the environment, and is difficult to reduce the poor stability of the sausage handling process caused by oil stains on the sausage casings, thereby increasing the probability of sausage casings being damaged or sausage bodies being deformed.

[0043] like Figures 1 to 4 As shown, in order to optimize the packaging efficiency and packaging effect of sausages, a preferred embodiment of the present invention proposes an automatic sausage packaging equipment, including a frame 1, a packaging film 2 and an intestine 3, a conveying component 4 is fixedly installed in the middle of the frame 1, a carrying plate 41 is movably installed on the upper part of the conveying component 4, a plurality of grooves that are evenly arranged and matched with the intestine 3 are evenly opened on the upper part of the carrying plate 41, a heat-sealing film is laid and installed on the upper surface of the groove, the intestine 3 is placed on the heat-sealing film, the packaging film 2 is fixedly installed on the frame 1, a heat-sealing component 5 is fixedly installed in the middle of the frame 1, the heat-sealing film and the packaging film 2 are vacuum-closed after passing through the heat-sealing component 5, and further comprises a cutting component 6 and a suction cup component 7.

[0044] By means of a carrier plate 41 of a fixed size, the loading operation of a fixed quantity or volume of sausage bodies 3 can be realized. A groove of a predetermined width is set in the carrier plate 41, and the groove is bent with a certain arc. When the sausage bodies 3 are put in, they stay at the bottom of the groove by themselves and maintain a predetermined distance with adjacent sausage bodies 3. In the subsequent packaging process, the mutual contact between the sausage bodies 3 is cut off. In the subsequent refrigeration and retrieval process of the sausage bodies 3, adhesion between the sausage bodies 3 due to the low temperature environment is avoided, thereby ensuring the independence of the sausage bodies 3 and facilitating the retrieval of users.

[0045] Furthermore, in order to achieve the continuity of the packaging process of the intestine 3, reduce the exposure time of the intestine 3 in the environment, and reduce the possibility of contamination, such as Figures 1 to 4 As shown, the cutting assembly 6 is movably installed in the heat sealing assembly 5, and the cutting assembly 6 is used to realize the unitized cutting of the outer packaging film 2 of the sausage body 3 after packaging. A slide rail 11 is fixedly installed in the middle of the frame 1, and a carrying frame 8 is slidably installed on the slide rail 11. The carrying frame 8 is located above the carrying plate 41, and an electric slider 12 for walking on the slide rail 11 is fixedly installed on the carrying frame 8. The suction cup assembly 7 is movably installed in the carrying frame 8, and the suction cup assembly 7 is adsorbed and cooperated with the casing of the outer layer of the sausage body 3. An external conveying frame 13 for supplying the sausage body 3 is rotatably installed on the side of the frame 1, and an external conveying belt is rotatably installed in the external conveying frame 13, and the upper surface height of the external conveying belt is consistent with the upper surface height of the carrying plate 41. The end of the external conveying frame 13 close to the middle of the base frame is movably installed with a telescopic plate 14 for adjusting the staying position of the sausage body 3.

[0046] The continuous supply of the sausage 3 by the external conveying frame 13 reduces the manual involvement in the packaging process, thereby enhancing the sterilization of the packaging environment; the vacuum packaging of the heat sealing component 5 and the cutting operation of the cutting component 6 improve the degree of automation in the packaging process of the sausage 3, improve efficiency, and reduce the packaging time of the sausage 3, thereby reducing the probability of it being contaminated or oxidized by the external environment; the quantitative transportation and position conversion of the sausage 3 are achieved through the autonomous operation of the carrying frame 8 and the inner suction cup component 7; the vacuum adsorption method is used to reasonably control the stress on the external casing of the sausage 3, thereby avoiding the probability of casing damage or deformation of the sausage 3, which is beneficial to improving the overall quality of the sausage 3 after packaging.

[0047] Furthermore, in order to adapt the size of the intestine 3 and optimize the external force when the intestine 3 is transported, Figures 5 to 8As shown, the suction cup assembly 7 includes a vacuum suction cup 71 and a horizontal shaft 73. The vacuum suction cup 71 is fixedly mounted on the movable end of the telescopic rod 72. The inner side of the telescopic rod 72 is provided with an air groove connected to the inner side of the vacuum suction cup 71. The vacuum suction cup 71 is located above the intestine 3, and the vacuum suction cup 71 and the outer casing of the intestine 3 are adsorbed and matched. The horizontal shaft 73 is fixedly mounted on the middle part of the carrier frame 8. A plurality of groups of buckle grooves 731 are evenly spaced on the horizontal shaft 73. A plurality of groups of buckle rods 732 are fixedly mounted on the horizontal shaft 73. The buckle rods 732 Engaged with the snap-fit ​​groove 731, the telescopic rod 72 is fixedly installed at the end position of the snap-fit ​​rod 732, and a solenoid valve 733 for realizing air intake and exhaust inside the vacuum suction cup 71 is fixedly installed on the snap-fit ​​rod 732, and an air pipe 734 is connected between the solenoid valve 733 and the fixed end of the telescopic rod 72. An adjustment hole 735 for adjusting the installation spacing of the telescopic rod 72 is provided at the end of the snap-fit ​​rod 732, and the number of installed vacuum suction cups 71 is consistent with the number of sausage bodies 3 contained in the supporting plate 41, and the vacuum suction cup 71 is adsorbed and cooperated with the middle casing of the sausage body 3.

[0048] When working, according to the size and volume of the intestine 3 to be transported, a vacuum suction cup 71 with a suitable diameter and adsorption pressure is selected. During the installation of the vacuum suction cup 71, the adjacent vacuum suction cups 71 are kept at a suitable distance through the adjustment hole 735 and the buckle groove 731. When the electric slider 12 drives the carrier frame 8 and the suction cup assembly 7 to reach the position above the intestine 3 on the external conveying frame 13, the solenoid valve 733 controls the air flow to enter the telescopic rod 72, so that the telescopic rod 72 is extended and pushes the vacuum suction cup 71 to approach the intestine 3. The vacuum suction cup 71 is made of a flexible material. During the contact between it and the intestine 3, it deforms itself and adheres to the outer wheel of the intestine 3. The intestine 3 fits the contour. When the telescopic rod 72 reaches the maximum telescopic length, the vacuum suction cup 71 and the intestine 3 are adsorbed. Subsequently, the solenoid valve 733 is used to exhaust the air. While the inside of the vacuum suction cup 71 is vacuumed, the telescopic end of the telescopic rod 72 moves upward synchronously. Under the action of suction, the intestine 3 is lifted up, completing the preliminary transfer of the intestine 3. Subsequently, the electric slider 12 is further controlled to work so that the intestine 3 reaches the upper position of the supporting plate 41. Subsequently, the vacuum environment inside the vacuum suction cup 71 is released, and the intestine 3 falls into the groove of the supporting plate 41 under the action of gravity, and then moves to the packaging station for vacuum packaging.

[0049] Furthermore, the intestine 3 contains a large amount of meat material, and the intestine 3 undergoes fumigation and cooling during processing, and its outer casing is often attached with grease. In order to avoid the problem of reduced adsorption area and adsorption force of the vacuum suction cup 71 caused by grease adhesion, the handling stability of the intestine 3 is improved. Figure 1 and Figure 2As shown, a decontamination tray 9 is fixedly installed on one side of the frame 1, and the decontamination tray 9 is located at the outer side of the external conveying frame 13, and the carrying frame 8 is located in the upper middle position of the decontamination tray 9. The decontamination tray 9 contains food-grade cleaning liquid for cleaning the vacuum suction cup 71, and a fixing ring 91 is fixedly installed on the inner side of the decontamination tray 9. The fixing rings 91 are grouped in pairs, and a splash-proof ring 92 is installed on the inner side of each group of fixing rings 91. The splash-proof ring 92 is a semi-cylindrical structure. The highest position of the splash-proof ring 92 in the inclined state is higher than the static stop position of the vacuum suction cup 71. Dirt intercepting brushes 921 are arranged on both sides of the semi-cylindrical notch of the splash-proof ring 92, and there is a gap between the splash-proof ring 92 and the fixing ring 91. A compression spring 922 is connected, a pressing rod 93 is slidably installed in the middle of the decontamination tray 9, a "V"-shaped pressing plate 81 is obliquely installed in the middle of the carrying frame 8, the upper end of the pressing rod 93 slides with the inclined side wall of the pressing plate 81, the lower end of the pressing rod 93 is fixedly connected with a pressure belt 931, the other end of the pressure belt 931 is fixedly connected to the splash-proof ring 92 after sliding through the fixing ring 91, the rotation angle of the splash-proof ring 92 in the fixing ring 91 is 0~90 degrees, the liquid level of the cleaning liquid in the decontamination tray 9 is lower than the lowest outer arc height of the splash-proof ring 92, the vacuum suction cup 71 is located on the inner side of the splash-proof ring 92 and it is located below the axial position of the splash-proof ring 92.

[0050] During operation, under the initial condition, the lower pressure rod 93 is not subjected to force, and under the elastic force of the compression spring 922, the pressure belt 931 is in a horizontal resting state, and the splash-proof ring 92 is in the initial horizontal static position with the opening facing upward. After the vacuum suction cup 71 performs the rated number or quantity of intestine 3 transport operations, the electric slider 12 is operated to make it reach the upper position of the decontamination tray 9, and the lower pressure plate 81 comes into contact with the lower pressure rod 93, and the lower pressure rod 93 is moved downward by the squeezing action. At this time, under the pushing action of the lower pressure rod 93, the pressure belt 931 gradually presents a "V" shape bend, and pulls the splash-proof ring 92 to rotate during the bending process. At this time, the vacuum suction cup 71 is directly above the decontamination tray 9, accompanied by the rotation of the splash-proof ring 92. , the highest position of the splash-proof ring 92 gradually exceeds the position of the vacuum suction cup 71. When the carrier frame 8 reaches the predetermined position and stops, the splash-proof ring 92 maintains its tilted state after rotation. Affected by the blocking effect of the fixed ring 91 and the splash-proof ring 92, the environment in which the vacuum suction cup 71 is located is relatively closed. At this time, the two rows of dirt intercepting brushes 921 arranged on both sides of the notch of the splash-proof ring 92 are respectively located at the oblique upper and lower positions of the vacuum suction cup 71. In the subsequent cleaning process, the flushed cleaning liquid overflows from the oblique lower position of the dirt intercepting brush 921, and the grease or stains flushed off during the cleaning process stay and gradually accumulate and collect under the blocking effect of the dirt intercepting brush 921, thereby improving the subsequent overall maintenance and cleaning efficiency and preventing additional pollution caused by disorderly flow and splashing of oil.

[0051] Furthermore, since the suction part of the vacuum suction cup 71 is concave, in order to improve the cleanliness of the concave part, Figure 4 ,as well as Figures 6 to 8 As shown, a cam 94 is rotatably installed at the axial position of the fixed ring 91, a cleaning motor 95 is fixedly installed in the middle of the cleaning disk 9, a synchronous wheel 96 is cooperatively installed at the output shaft end of the cleaning motor 95 and the side wall of the cam 94, and a plurality of synchronous wheels 96 are meshed and transmitted through a synchronous belt 961, a waist-shaped groove is provided on the fixed ring 91, a scraping rod 97 is slidably installed in the waist-shaped groove, a scraping plate 971 is fixedly installed on the scraping rod 97, and the scraping plate 971 is located below the vacuum suction cup 71, and the cam 94 slides and squeezes with the upper end surface of the scraping plate 971 during rotation, and a cleaning head 98 for cleaning the inside of the vacuum suction cup 71 is coupled and installed on the scraping plate 971, and a through plate 99 is fixedly installed between the same group of fixed rings 91, the through plate 99 is located below the scraping plate 971, and an extrusion spring 991 is arranged between the through plate 99 and the scraping plate 971.

[0052] During operation, when the vacuum suction cup 71 reaches the predetermined cleaning position, the cleaning motor 95 is started to operate. At this time, under the meshing action of the synchronous wheel 96 and the synchronous belt 961, the cam 94 rotates and intermittently squeezes the scraper plate 971. Under the elastic force of the squeezing spring 991, the scraper plate 971 performs intermittent lifting and lowering actions, and drives the cleaning head 98 to move synchronously. At this time, along with the rise, its end enters the inner recessed part of the vacuum suction cup 71 and cleans it, reducing the grease or stain residue on the inner wall of the vacuum suction cup 71 and improving its adsorption stability in subsequent work. At the same time, in order to improve the cleaning effect of stains or grease, the solenoid valve 733 can be controlled to work, and the airflow can be controlled to be discharged from the vacuum suction cup 71 position to perform pneumatic stain blowing, thereby further optimizing the cleaning effect.

[0053] Furthermore, in order to achieve continuous cleaning operation, the stable working time of the vacuum suction cup 71 is increased, such as Figures 6 to 10 As shown, the cleaning head 98 is conical, and the outer layer of the cleaning head 98 is provided with a soft cleaning layer 981, and the cleaning layer 981 fits with the inner wall of the vacuum suction cup 71 during operation, and an infusion groove for the flow of cleaning liquid is provided on the inner side of the scraping rod 97, and a hole groove 972 connected to the infusion groove is provided in the middle of the cleaning head 98, and a nozzle 982 for the outflow of cleaning liquid is provided at the upper part of the conical end of the cleaning head 98, and a spiral rotating groove 983 is provided at the lower part of the cleaning head 98, and a penetration rod 992 is fixedly installed on the through plate 99, and a ball 993 that rotates with the rotating groove 983 is provided on the upper end of the penetration rod 992.

[0054] During operation, the supply of cleaning liquid can be realized through the infusion groove on the inner side of the scraping rod 97, so that the cleaning liquid is sprayed out from the nozzle 982 at the end of the cleaning head 98, directly reaching the inner wall of the vacuum suction cup 71, and forming a flushing effect on the oil stains adhered to its surface. The cleaning layer 981 arranged on the outer layer of the cleaning head 98 can reduce the wear of the inner wall of the vacuum suction cup 71 in the process of removing the oil stains, so that the inner wall of the vacuum suction cup 71 maintains a smooth property. At the same time, with the rise and fall of the cleaning head 98, the insertion rod 992 and the cleaning head 98 are intermittently separated and merged. At this time, due to the spiral cooperation between the rotating groove 983 and the ball 993, the cleaning head 98 rotates synchronously during the rising process, further improving the oil removal effect on the inside of the vacuum suction cup 71, and along with the self-rotation of the cleaning head 98, after leaving the vacuum suction cup 71, the oil or cleaning liquid can be thrown off through the centrifugal action, realizing self-cleaning, and then realizing continuous cleaning operation. After the cleaning operation is completed, the solenoid valve 733 controls the continuous outflow of gas, thereby realizing the drying process of the vacuum suction cup 71, which is convenient for the next batch of intestines 3 to be transported.

[0055] In addition, the present invention also provides a packaging method of sausage automatic packaging equipment, comprising the following steps:

[0056] S1. Sausage processing: The sausages are processed and cut by the existing sausage processing equipment to make the sausages into columns with uniform length and thickness. Then, according to the packaging quantity requirements, an appropriate number of vacuum suction cups 71 are installed in the suction cup assembly 7, and the spacing between the vacuum suction cups 71 is adjusted to match the length of the sausage body 3. Then, a bottom heat-sealing film for packaging the sausage body 3 is laid on the carrier plate 41, and the external conveyor belt and the conveying assembly 4 are started to operate to convey and supply the sausage body 3.
