Description

Technical Field

[0001] The present invention relates to the technical field of cup-shaped yogurt production, and particularly to a filling production line.

Background Art

[0002] In the technical field of yogurt filling production, a stepping method is adopted to convey yogurt cups, and the conveying power comes from a swing mechanism based on a parallel four-bar linkage structure. As is well known, the movable link in the parallel four-bar linkage structure can perform a rotary motion in space on the premise of maintaining a horizontal spatial attitude. The motion range of the movable link projects on the horizontal plane to form a reciprocating linear motion in the horizontal direction and projects on the vertical plane to form a reciprocating linear motion in the vertical direction, and the two motions are synchronized. A mold for mounting yogurt cups is provided on the movable link. When the movable link moves, the yogurt cups will obtain a horizontal displacement operation and at the same time form a reciprocating motion in the vertical direction. Observed from the outside, it moves in a trajectory similar to a parabola. This causes the yogurt cups in the stepping conveying process to reciprocate in the vertical direction. This motion process is short, and it is very easy to shake the cup body and make it deviate from the given position, which has a negative impact on the subsequent filling operation.

[0003] In addition, common yogurt cups are mainly packaged in plastic cups, especially in the form of plastic cups produced based on the multi-cup technology. This packaging form has only one cavity for containing materials in the cup body, and yogurt is filled in this cavity. The single-form yogurt products show a weak market demand in the dairy product market competition. After all, only one product is provided to consumers in a single cup body. If the taste is only the original flavor, it will surely be at a disadvantage in the market competition with other products filled with flavors different from the original flavor. On a larger scale, even if other flavors can be provided but only a single flavor of yogurt product is provided in the same cup body, it still lacks selling points compared with other newer dairy products.

[0004] Therefore, the prior art has developed a plastic cup with two cavities. Different flavors of yogurt can be installed in the two cavities according to requirements, or one cavity is filled with yogurt and the other cavity is filled with granular biscuits or other foods to improve the eating experience of consumers and enhance the market competitiveness of the products. During the production process, after filling the two materials into the two cavities respectively, the plastic cups are conveyed to the film sealing station for heat sealing of the cover film to seal the two cavities. However, during the conveying process, the phenomenon of the two materials mixing in the cups will occur. In order to prevent the above phenomenon from occurring, it is necessary to first fill one cavity, then cover the cover film on the two cavities, and heat seal the cover film so that part of the cover film seals the filled cavity, and then manually uncover the other part of the cover film to open the other cavity for the next filling. However, the manual film uncovering method not only results in additional labor costs, but also leads to a reduction in production efficiency and the occurrence of missed film uncovering, thus greatly increasing the production and manufacturing costs.

Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a filling production line, which can completely avoid the vertical movement of the yogurt cups during the translational conveyance of the yogurt cups, thereby preventing the yogurt cups from leaving a given position and facilitating subsequent filling operations; and can realize automatic film removal, thereby avoiding the occurrence of film leakage and reducing manufacturing costs.

[0023] Advantages of the present invention:

[0024] 1. When the translation driving component drives the conveying component to reciprocate in the horizontal direction, the design of the vertical directional transmission component can make the conveying component slide in the conveying direction relative to the lifting driving component, so as to avoid the lifting driving component interfering with the translation of the conveying component. When the lifting driving component drives the conveying component to reciprocate in the vertical direction, the horizontal directional transmission component can make the conveying component move in the vertical direction relative to the translation driving component, thereby avoiding the translation driving component interfering with the lifting and lowering of the conveying component. It can be seen that the translational movement and the lifting and lowering movement of the conveying component in the present invention do not interfere with each other, that is, the movement of the conveying component in the vertical direction is completely avoided when the conveying component is translated, and the yogurt cup will not be lifted when the conveying component is driven to translate and transport the yogurt cup, thereby avoiding the yogurt cup from leaving the given position, which is convenient for subsequent filling operations.

[0025] When the film peeling mechanism of the present invention is working, the third driving unit drives the first rocker arm to swing, thereby driving the connecting rod to perform a rotary motion while maintaining a horizontal state. The rotary motion of the connecting rod drives the third rocker arm to swing, and the swing of the third rocker arm drives the air pipe to rotate, thereby driving the suction cup to swing. At the same time, the swing of the first rocker arm will also drive the bracket to perform a rotary motion while maintaining a horizontal state, thereby driving the second rocker arm to swing. In this way, when the third driving unit drives the disk surface of the suction cup to swing to a downward direction, the suction cup absorbs the cover film, and then the third driving unit drives the suction cup to swing and the bracket to swing, so that the suction cup peels off the cover film, and then the suction cup releases the cover film. The cover film remains peeled off under the action of the limit rod, so as to facilitate the subsequent material filling. Subsequently, the third driving unit drives the first rocker arm to swing in the opposite direction, so that the suction cup and the bracket swing in the opposite direction until the disk surface of the suction cup is in a downward position. After the suction cup absorbs the cover film, the third driving unit drives the bracket to swing and the suction cup to swing, so as to perform the film peeling action. It can be seen from this that the film peeling mechanism of the present invention can realize automatic film peeling, avoid the occurrence of film peeling leakage, and reduce the manufacturing cost.

[0026] 2. The lifting drive component includes a first driving unit and a first rotating shaft, and the vertical directional transmission component includes a support block and a slider. The bottom end of the support block is fixedly connected to the first rotating shaft, and the top end of the support block is rotatably connected to the slider through a pin shaft. The slider is slidably connected to the conveying component and can slide back and forth along the conveying direction of the conveying component. The first driving unit drives the first rotating shaft to rotate to make the support block swing. The swing of the support block can change the vertical distance between the top end of the support block and the first rotating shaft and the distance in the conveying direction. The change in the vertical distance drives the conveying component to reciprocate in the vertical direction through the slider. The change in the distance in the conveying direction can eliminate the influence of the sliding of the slider, thereby completely avoiding the translation of the conveying component and the translation driving component. The horizontal directional transmission component can make the conveying component move in the vertical direction relative to the translation driving component, so that when the conveying component is lifted and lowered, the translation of the conveying component and the lifting and lowering of the translation driving component can be completely avoided.

[0027] 3. A rocker is fixed to the first rotating shaft. The first rotating shaft includes an active first rotating shaft and at least two driven first rotating shafts. The rocker includes an active rocker fixed to the active first rotating shaft and a driven rocker fixed to the driven first rotating shaft. A first transmission rod is rotatably connected between the active rocker and an adjacent driven rocker and between two adjacent driven rockers. The first driving unit drives the active first rotating shaft to rotate so as to swing the rocker, and the swinging of the rocker drives the driven first rotating shaft to rotate. With such a design, it is possible to use one first driving unit to drive the support blocks on the active first rotating shaft and the driven first rotating shafts to swing synchronously, thereby reducing the number of first driving units used and simplifying the structure. In addition, such a design also enables the designer to reasonably configure different numbers of driven first rotating shafts according to the lengths of different conveying components, so as to ensure the smoothness of the lifting movement of the conveying components.

[0028] 4. A slide rail is installed at the bottom of the conveying component, and a chute that is slidably matched with the slide rail is provided at the top of the slider. With such a design, it is possible to ensure the smoothness when the slider and the second chute slide relative to each other.

[0029] 5. The translation driving component includes a rocker arm and a second driving unit for driving the rocker arm to swing. The horizontal orientation transmission assembly includes a connecting portion and a guiding portion that is vertically slidably matched with the connecting portion. The connecting portion is fixed to the conveying component, and the guiding portion is fixed to the rocker arm. The swinging of the rocker arm is transmitted to the connecting portion through the guiding portion, so that the connecting portion drives the conveying component to translate. Since the conveying component is slidably connected to the slider, the lifting driving component will not interfere with the translation of the conveying component. And the vertical sliding fit between the connecting portion and the guiding portion can prevent the conveying component from generating a lifting movement. Therefore, when the conveying component translates, the lifting movement of the conveying component and the translation of the lifting driving component can be completely avoided.

[0030] 6. The second driving unit includes a second motor and a second active rotating shaft. The rocker arm includes an active rocker arm fixed to the second active rotating shaft, and the second motor is connected to the second active rotating shaft. It is applicable to conveying components with a relatively short length.

[0031] 7. The second driving unit further includes a second driven rotating shaft, and the rocker arm further includes a driven rocker arm fixed to the second driven rotating shaft. A second transmission rod is rotatably connected between the active rocker arm and an adjacent driven rocker arm and between two adjacent driven rocker arms. With such a design, the translation driving component can be applicable to conveying components with a relatively long length, and only one second motor is required, and the structure is simple.

[0032] 8. The connecting portion is provided with a guiding hole, and the guiding portion is a roller that reciprocally slides vertically along the guiding hole. With such a design, it is possible to improve the smoothness of the sliding and avoid the occurrence of jamming phenomena that cause the conveying component to be unable to lift.

[0033] 9. The outer circumference of the roller is provided with a guide groove that slides with the inner wall of the guide hole. This design improves the guiding effect and the smoothness of the sliding fit.

[0034] 10. A notch with an opening facing downward is provided on the support plate, the notch is located between the limit rod and the gas delivery pipe, and the inner side of the notch is tangent to the outer peripheral surface of the limit rod. With such a design, when the cover film is transported, the notch design can make the cover film move smoothly to the outside of the support.

[0035] 11. The film peeling mechanism further includes a cover film guide assembly, which includes a guide member arranged outside the bracket and extending along the length direction of the support plate, and the guide member is connected with the limit rod. The guide member is designed to keep the cover film in an peeled state along its movement path.

[0036] 12. The guide member includes an upper guide bar and a lower guide bar arranged in parallel, and the upper guide bar and the lower guide bar bend to the same side along the conveying direction and then extend straightly. Such a design can gradually guide the cover film to flip to a vertical state on the movement path of the cover film, thereby making the cavity fully open and exposed.

[0037] 13. The active swing arm unit also includes a connecting block, one end of which is fixedly connected to the second rotating shaft, and the other end of which is connected to the bracket rod connected to the first rocker arm. This design can make the back and forth swinging motion of the bracket more stable.

[0038] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0056] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0057] Embodiment 1

[0058] Reference Figures 1 to 2As shown in the figure, the yogurt cup in this embodiment has a first cavity 01 and a second cavity 02. Different materials are filled into the first cavity 01 and the second cavity 02 respectively. After the filling of the first cavity 01 and the second cavity 02 is completed, the cover film is heat-sealed.

[0059] As Figures 3 to 9 shown in the figure, the filling production line for filling the above-mentioned yogurt cup in this embodiment includes a frame 10 and a material support assembly arranged on the frame 10. The material support assembly includes a plurality of support plates 11 arranged at equal intervals and parallel to each other in the horizontal direction. The support plates 11 extend straight along the conveying direction of the yogurt cup. The two ends of the plurality of support plates 11 are connected and fixed by rods 12 respectively. The outermost support plate 11 is fixed on the frame 10 through a vertical plate 13. A straight distribution conveying channel is formed between two adjacent support plates 11. The top flange of the yogurt cup, that is, the edge part of the cup mouth, is supported by the support plate 11, and the cup body of the yogurt cup is located in the conveying channel.

[0060] The filling production line in this embodiment includes a step conveying device. The step conveying device includes a conveying component, a translation driving component, and a lifting driving component. Among them, the conveying component includes a plurality of conveying plates 110 arranged at equal intervals and parallel to each other. The two ends of the plurality of conveying plates 110 are fixedly connected by connecting rods 112. One of the conveying plates 110 is arranged between two adjacent support plates 11. A jacking part is arranged on the conveying plate 110. The jacking part includes a plurality of molds 114 arranged at equal intervals along the length direction of the conveying plate 110. A limiting opening 111 is formed between two adjacent molds 114. The cup body of the yogurt cup is located in the limiting opening 111. The edge of the cup mouth of the yogurt cup is pressed on the mold 114, and two adjacent molds 114 hold the yogurt cup.

[0061] As Figure 6As shown, the lifting drive component includes a first drive unit and a first rotating shaft. The first drive unit includes a first motor 120. The first rotating shaft includes an active first rotating shaft 151 and at least two driven first rotating shafts 152. The active first rotating shaft 151 and the driven first rotating shafts 152 are spaced apart and parallel to each other along the length direction of the conveying channel. Taking the first rotating shaft including an active first rotating shaft 151 and three driven first rotating shafts 152 as an example, one of the three driven first rotating shafts 152 is located on one side of the active first rotating shaft 151, and the other two are spaced apart on the other side of the active first rotating shaft 151. A rocker is fixedly connected to the first rotating shaft. The rocker includes an active rocker 153 fixed to the active first rotating shaft 151 and a driven rocker 154 fixed to the driven first rotating shaft 152. A first transmission rod 155 is rotatably connected between the active rocker 153 and the adjacent driven rocker 154 and between two adjacent driven rockers 154. The first motor 120 is fixedly connected to the active first rotating shaft 151 through a speed reducer or directly. The first motor 120 drives the active first rotating shaft 151 to rotate to drive the active rocker 153 to swing. The swing of the active rocker 153 drives the driven rocker 154 to swing through the first transmission rod 155. The swing of the driven rocker 154 drives the driven first rotating shaft 152 fixedly connected thereto to rotate.

[0062] A vertical directional transmission component is provided between the active first rotating shaft 151 and the conveying plate 110 and between the driven first rotating shaft 152 and the conveying plate 110. The vertical directional transmission component includes a slider 130 and a support block 140. The above support blocks 140 are respectively fixed on the active first rotating shaft 151 and the driven first rotating shafts 152. The top end of the support block 140 is rotatably connected to the slider 130 through a pin shaft. A chute is provided at the top of the slider 130. A slide rail 113 parallel to the conveying plate 110 is provided at the bottom of at least one conveying plate 110. The chute is slidably connected to the slide rail 113 and can reciprocate along the length direction of the slide rail 113. The rotation of the active first rotating shaft 151 and the driven first rotating shafts 152 can drive the support blocks 140 to swing synchronously. The swing of the support blocks 140 will drive the slider 130 to reciprocate in the vertical direction and slide reciprocally along the slide rail 113. The reciprocating movement of the slider 130 in the vertical direction drives the conveying component to reciprocate in the vertical direction of the conveying channel.

[0063] The translation drive component includes a second drive unit and a rocker arm. The second drive unit drives the rocker arm to swing back and forth. The second drive unit includes a second motor 181, a second driving rotating shaft 182, and a second driven rotating shaft 183. The second driven rotating shaft 183 is rotatably connected to a support 184, and the support 184 is fixed to the frame 10. The rocker arm includes a driving rocker arm 185 fixed to the second driving rotating shaft 182 and a driven rocker arm 186 fixed to the second driven rotating shaft 183. A second transmission rod 187 is rotatably connected between the driving rocker arm 185 and the driven rocker arm 186. The second motor 181 is fixedly connected to the second driving rotating shaft 182 through a speed reducer or directly. The second motor 181 drives the second driving rotating shaft 182 to rotate so that the driving rocker arm 185 on the second driving rotating shaft 182 swings. The swing of the driving rocker arm 185 drives the driven rocker arm 186 to swing through the second transmission rod 187.

[0064] A horizontal directional transmission assembly is provided between the driving rocker arm 185 and the conveying component and between the driven rocker arm 186 and the conveying component. The horizontal directional transmission assembly includes a connecting portion 160 and a guiding portion 170 that is vertically slidably engaged with the connecting portion 160. The connecting portion 160 is a vertical connecting plate provided on the conveying component. A vertically extending guiding hole 161 is provided on the vertical connecting plate. The guiding portion 170 is provided on the driving rocker arm 185 and the driven rocker arm 186. The guiding portion 170 is a roller. A guiding groove that is slidably engaged with the inner wall of the guiding hole 161 of the vertical connecting plate is provided on the outer peripheral side of the roller. In this embodiment, the synchronous swing of the driving rocker arm 185 and the driven rocker arm 186 will drive the roller to reciprocate horizontally while also sliding vertically along the guiding hole 161. The horizontal reciprocating movement of the roller will drive the vertical connecting plate to drive the conveying component to reciprocate horizontally in the conveying channel. The sliding of the roller will prevent the conveying component from moving in the vertical direction. Thus, the conveying component can only make a reciprocating movement in the horizontal direction.

[0065] In the drawings of this embodiment, the direction of the next working station of this step conveyor device is the front, and the direction of the previous working station of this step conveyor device is the back. The translation drive component and the lifting drive component in this embodiment drive the conveying component to move in an asynchronous manner. Specifically, when the yogurt cup is moved towards the next working station direction through the conveying component, the conveying component is at a high position, and the first motor 120 stops working. At this time, the support block 140 is perpendicular to the horizontal line (as Figure 7As shown, the edge of the yogurt cup mouth presses on the mold 114 and detaches from the support plate 11. The second motor 181 drives the second driving rotating shaft 182 to rotate forward so that the driving rocker arm 185 on the second driving rotating shaft 182 swings forward. The swing of the driving rocker arm 185 drives the follower rocker arm 186 to swing forward through the second transmission rod 187. The synchronous swing of the driving rocker arm 185 and the follower rocker arm 186 drives the roller to swing forward. The forward swing of the roller is split into forward movement in the horizontal direction and vertical sliding along the guiding hole 161. The sliding of the roller will prevent the conveying component from moving in the vertical direction. The forward movement of the roller will drive the vertical connecting plate to drive the conveying component to move forward in the horizontal direction of the conveying channel. Since the slide rail 113 on the conveying component is slidably connected to the slider 130, the translation of the conveying component will not be interfered by the vertical directional transmission component, thus avoiding driving the lifting driving component to translate.

[0066] After the yogurt cup is conveyed to the next working station, the second motor 181 stops working. The first motor 120 drives the active first rotating shaft 151 to drive the active rocker 153 to swing forward. The swing of the active rocker 153 drives the follower rocker 154 to swing forward through the first transmission rod 155. The swing of the follower rocker 154 drives the driven first rotating shaft 152 fixedly connected thereto to rotate. The synchronous rotation of the active first rotating shaft 151 and the driven first rotating shaft 152 drives all the support blocks 140 to swing forward synchronously so that the conveying component descends to the low position (as Figure 9 shown). During the forward swing of the support block 140, it will drive the slider 130 to move downward and at the same time drive the slider 130 to slide forward along the slide rail 113. The downward movement of the slider 130 will drive the conveying component to descend to the low position. The downward movement of the conveying component makes the guiding hole 161 move downward along the roller, thus avoiding being interfered by the horizontal directional transmission component to avoid driving the translation driving component to descend. And the forward sliding of the slider 130 along the slide rail 113 will completely prevent the conveying component from moving in the horizontal direction. After the conveying component descends to the low position, the body of the yogurt cup detaches from the limiting port 111, and the edge of the yogurt cup mouth presses on the support plate 11, waiting for the conveying component on the next working station to receive it.

[0067] After the conveying component descends to the low position, the first motor 120 stops working, and the second motor 181 drives the second active rotating shaft 182 to rotate backward so that the active rocker arm 185 on the second active rotating shaft 182 swings backward, and the swing of the active rocker arm 185 drives the slave rocker arm 186 to swing backward through the second transmission rod 187. The synchronous swing of the active rocker arm 185 and the slave rocker arm 186 drives the roller to swing backward, and the backward swinging of the roller is divided into horizontal backward movement and vertical sliding along the guide hole 161. The sliding of the roller will prevent the conveying component from moving in the vertical direction. The successive movement of the roller will drive the vertical connecting plate to drive the conveying component to move backward in the horizontal direction of the conveying channel. Since the slide rail 113 on the conveying component is slidably connected to the slider 130, the translation of the conveying component will not be interfered by the vertical directional transmission component, thereby avoiding driving the lifting drive component to translate.

[0068] After the conveying component moves backward to its position, the second motor 181 stops working, and the first motor 120 drives the active first rotating shaft 151 to drive the active rocker 153 to swing backward. The swing of the active rocker 153 drives the driven rocker 154 to swing backward through the first transmission rod 155. The swing of the driven rocker 154 drives the driven first rotating shaft 152 fixedly connected thereto to rotate. The synchronous rotation of the active first rotating shaft 151 and the driven first rotating shaft 152 drives all the supporting blocks 140 to swing backward synchronously. When the supporting blocks 140 are perpendicular to the horizontal line (such as Figure 9 As shown in the figure, the conveying component rises to a high position. When the support block 140 swings backward, it drives the slider 130 to rise and slide backward along the slide rail 113. The rise of the slider 130 drives the conveying component to rise to a high position. The rise of the conveying component causes the guide hole 161 to move upward along the roller, thereby avoiding interference from the horizontal directional transmission component to avoid driving the translation drive component to rise. The slider 130 slides backward along the slide rail 113 to completely avoid the horizontal movement of the conveying component. After the conveying component rises to a high position, the cup body of the yogurt cup on the previous station is inserted into the limit opening 111, and the edge of the yogurt cup mouth is pressed on the mold 114, and then the above operation steps are performed again, thereby realizing the step-by-step conveying of the yogurt cup.

[0069] It can be seen that in this embodiment, the translational movement and the lifting movement of the conveying component do not interfere with each other, that is, when the conveying component is driven to translate, the vertical movement of the conveying component is completely avoided. Therefore, when the conveying component is driven to translate to convey the yogurt cup, the yogurt cup will not be lifted, thereby avoiding the yogurt cup from leaving the given position, which is convenient for subsequent filling operations.

[0070] The filling production line of the present invention also includes a film peeling mechanism, which is used to peel off the cover film on the yogurt cup, that is, during production, such as Figure 2As shown, a portion of the cover film is first heat-sealed and fixed on the yogurt cup to seal the first cavity 01, and the other portion of the cover film is covered on the second cavity 02. The film peeling mechanism is used to peel off the cover film 03 to open the second cavity 02, thereby facilitating the later filling of the second cavity 02 with materials.

[0071] like Figures 10 to 13 As shown, the film peeling mechanism in this embodiment includes a film peeling assembly, which includes a bracket 210, an active swing arm unit, a driven swing arm unit, a posture adjustment swing unit and a third driving unit. The bracket 210 is located above the support plate 11. The bracket 210 includes two parallel bracket plates 211 and a bracket rod 212 connected between the two ends of the two bracket plates 211. The bracket plate 211 is provided with a mounting hole, and a bearing is provided between the bracket rod 212 and the mounting hole, so that the bracket rod 212 can rotate relative to the bracket plate 211. The active swing arm unit includes a first rocker arm 243 and a connecting block 245, the driven swing arm unit includes two second rockers 246, and the posture adjustment swing unit includes an air pipe 220, a suction cup 230, a third rocker arm 244 and a connecting rod 242. The air pipe 220 is rotatably connected between the two bracket plates 211, the air pipe 220 is parallel to the bracket rod 212, and the suction cups 230 are distributed on the air pipe 220 at equal intervals. The third driving unit includes a third motor 240 and a second rotating shaft 241 connected to the third motor 240, the second rotating shaft 241 is horizontally arranged and parallel to the support plate 11, the bottom end of the first rocker arm 243 and the bottom end of the connecting block 245 are respectively fixedly connected to the second rotating shaft 241, the top end of the first rocker arm 243 is rotatably connected to one end of the connecting rod 242, the top end of the connecting block 245 is fixedly connected to one of the support rods 212, and one end of the support rod 212 is fixedly connected to the portion between the bottom and top ends of the first rocker arm 243, one end of the air delivery pipe 220 extends out of the outside of the bracket 210 and is fixedly connected to the bottom end of the third rocker arm 244, The top end of the third rocker arm 244 is rotatably connected to the connecting rod 242 via a pin shaft, the top end of the second rocker arm 246 is fixedly connected to another bracket rod 212, and the bottom end of the second rocker arm 246 is rotatably connected to the support plate 11, that is, the support plate 11 is provided with a support seat 14 which is relatively fixed to the support plate 11, the support seat 14 is provided with a third rotating shaft 15, and the bottom end of the second rocker arm 246 is fixedly connected to the third rotating shaft 15, thereby enabling the second rocker arm 246 to achieve a swinging motion; or the support plate 11 is provided with a hinge seat, and the bottom end of the second rocker arm 246 is rotatably connected to the hinge seat via a pin shaft, thereby also enabling the second rocker arm 246 to achieve a swinging motion.

[0072] When the film peeling mechanism is working, the third motor 240 drives the second rotating shaft 241 to rotate to drive the first rocker arm 243 and the connecting block 245 to swing. The swing of the first rocker arm 243 will simultaneously drive the connecting rod 242 and the bracket 210 to swing back and forth. The movement range of the bracket 210 is perpendicular to the horizontal direction. The movement of the connecting rod 242 will drive the third rocker arm 244 to swing. The swing of the third rocker arm 244 will drive the air pipe 220 to rotate. The rotation of the air pipe 220 will drive the suction cup 230 to swing. At the same time, the back and forth swinging of the bracket 210 will also drive the suction cup 230 to swing through the air pipe 220. The movement range of the suction cup 230 is located above the material support assembly.

[0073] In addition, a limiting rod 250 parallel to the gas pipe 220 is connected between the two support plates 211 in this embodiment. The limiting rod 250 corresponds to the gas pipe 220 one by one. The limiting rod 250 is located on one side of the gas pipe 220. In the working state of this embodiment, the limiting rod 250 can be located above the second cavity 02. The height of the limiting rod 250 in the vertical direction is greater than the lowest height of the plate surface of the suction cup 230 in the vertical direction. A notch 213 with an opening facing downward is also provided on the support plate 211. The notch 213 is located between the limiting rod 250 and the gas pipe 220. The inner side surface of the notch 213 is tangent to the outer peripheral surface of the limiting rod 250. In this way, when the plastic cup is transported, the cover film 03 can move to the outside of the support under the guidance of the limiting rod 250 and the notch 211.

[0074] In addition, the film peeling mechanism in the present embodiment also includes a cover film guide assembly, which includes a guide member 260 arranged on the outside of the bracket 210 and extending along the length direction of the support plate 11, that is, the guide member 260 extends along the conveying direction of the plastic cup, and the guide member 260 is connected with the limit rod 250. In this way, when the yogurt cup moves to the outside of the bracket and continues to be conveyed, the cover film 03 can always be placed on the guide member 260 to keep the cover film 03 in an uncovered state, wherein the guide member 260 includes an upper guide bar 261 and a lower guide bar 262 arranged in parallel, and the upper guide bar 261 and the lower guide bar 262 are bent to the same side along the conveying direction and then extend straight. In this embodiment, the upper guide bar 261 and the lower guide bar 262 are bent to the right side at the same angle along the conveying direction and then extend straight. In this way, the cover film 03 can be gradually guided to flip to a vertical state on the movement path of the cover film 03, thereby making the second cavity 02 completely open and exposed.

[0075] In order to describe this embodiment more clearly, in this embodiment, after the yogurt cup is placed on the stepping conveyor, the second cavity 02 is located on one side of the first cavity 01 as the left side, and the first cavity 01 is located on one side of the second cavity 02 as the right side. Figures 10 to 13As shown, in this embodiment, the disk surface of the suction cup 230 is parallel to the horizontal plane and is arranged downward. At this time, the disk surface of the suction cup is at the lowest height in the vertical direction. The suction cup 230, the first swing arm 243, the second swing arm 246, the third swing arm 243 and the bracket 210 are all in the first position. The air delivery pipe 220 is connected to a negative pressure generator, and the negative pressure generator sucks air to make the suction cup 230 adsorb the cover film 03. Subsequently, the third motor 240 drives the second rotating shaft 241 to rotate to drive the first swing arm 243 to swing 90° to the right. The swing of the first swing arm 243 will simultaneously drive the connecting rod 242 and the bracket 210 to perform swing movements. The second swing arm 246 swings driven by the bracket 210. The movement of the connecting rod 242 will drive the third swing arm 244 to swing 90° to the right. The swing of the third swing arm 244 will drive the air delivery pipe 220 to rotate 90°, so that the disk surface of the suction cup 230 swings to a state parallel to the vertical plane. In addition, the swing movement of the bracket 210 will also move the suction cup 230 to the right by a certain distance. During this process, while the suction cup 230 undergoes a spatial position movement, its spatial attitude also changes through self-rotation. Thus, the suction cup 230 can uncover the cover film 03. At this time, the suction cup 230, the first swing arm 243, the second swing arm 246, the third swing arm 243 and the bracket 210 are all in the second position (as Figures 14 to 16 shown).

[0076] It should be noted that during the process of the suction cup 230 moving from the first position to the second position, since the cover film 03 is flexible, the cover film 03 will move upward over the limiting rod 250. In this way, when the suction cup 230 is in the second position, after the negative pressure generator ventilates to make the suction cup 230 release the cover film 03, the cover film 03 will be placed on the limiting rod 250 to keep the cover film 03 in the uncovered state. In the state where the cover uncovering assembly is in the second position, the connection between the limiting rod 250 and the upper guide bar 261 means that the end of the limiting rod 250 is directly opposite to the end of the upper guide bar 261. When the yogurt cup is conveyed by the conveying component to the next station for filling, during the process of being conveyed to the next station, the cover film 03 passes through the notch 213 under the guidance of the limiting rod 250 and is then placed on the guiding member 260. The guiding member 260 keeps the cover film 03 in the uncovered state during the conveying process. After the suction cup 230 releases the cover film 03, the third motor 240 drives the second rotating shaft 241 to rotate to drive the first swing arm 243 to swing 90° to the left, so that the suction cup 230, the first swing arm 243, the second swing arm 246, the third swing arm 243 and the bracket 210 move to the first position, thereby uncovering the cover film 03 on the yogurt cup conveyed from the previous station, and thus realizing continuous film uncovering. It can be seen that by adopting the film uncovering mechanism of this embodiment, automatic film uncovering can be realized, avoiding the occurrence of missed film uncovering phenomena and reducing the manufacturing cost.
