Description

Technical Field

[0001] This application relates to the field of food vending machines, and in particular to a food container tearing device and a food vending machine. Background Technology

[0002] Food vending machines are becoming increasingly widespread, providing people with a convenient way to purchase food. These machines typically feature removable lids on the food containers, which protect the food and enhance its safety.

[0003] Normally, food vending machines heat the food in the container before delivering it to the user. However, because the container has a lid, the heating time is slightly longer, and for some foods, the taste is better after removing the lid and heating. Therefore, some food vending machines are equipped with a suction cup mechanism for lifting the lid. Before heating, the suction cup holds the lid in place, and then it can be lifted directly.

[0004] With the development of pre-prepared food technology and the emergence of airtight food containers, the shelf life of food has been greatly extended. Under the same conditions, airtight containers are better able to maintain the taste and quality of food. Similarly, for the sake of user experience, there is a need for heating after tearing off the film, but the suction cup mechanism mentioned above is clearly not suitable for airtight food containers. Summary of the Invention

Detailed Implementation

[0063] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0064] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be intermediate components present. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be intermediate components present.

[0065] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0066] Please refer to Figures 1 to 11 The lunchbox film-tearing device 100a in this embodiment is used to tear off the sealing film 9 on the sealed lunchbox 4. The lunchbox film-tearing device 100a includes a motion component 10, a clamping component 11, and a swing connection component 12. The motion component 10 has an output end that can move along the X, Y, and Z directions. The clamping component 11 is used to clamp the sealing film 9 of the lunchbox 4, specifically clamping one corner of the sealing film 9, and the clamping component 11 is swingably connected to the output end of the motion component 10 through the swing connection component 12.

[0067] Based on this, when the clamping assembly 11 clamps the sealing film 9, the motion assembly 10 can drive the clamping assembly 11 to move, thereby applying a tearing force to the sealing film 9. Specifically, after the tearing force is applied, the clamping assembly 11 swings from a first position to a second position relative to the output end of the motion assembly 10 along a first straight line. After the tearing force disappears, the clamping assembly 11 swings from the second position back to the first position.

[0068] In this embodiment, the cooperation of the moving component 10 and the clamping component 11 applies a tearing force to the sealing film 9 of the lunchbox 4, thereby tearing the film. The specific tearing process is as follows: After the clamping component 11 clamps one corner of the sealing film 9, the moving component 10 begins to move, for example, in a diagonal direction. In the early stage of movement (or the early stage of tearing), due to the action of the swing connecting component 12, the clamping component 11 swings from the first position to the second position, which gradually increases the tearing force, thus ensuring smooth tearing. This is because, initially, the proportion of the sealing film 9 detached from the lunchbox 4 is very small. If a strong tear is applied at this time, it is very likely that the sealing film 9 will break, resulting in a very small part of the sealing film 9 being on the clamping component 11, while the vast majority of the sealing film 9 is still adhered to the lunchbox 4. However, in this embodiment, the swinging motion gradually increases the tearing force, which can gradually increase the proportion of the sealing film 9 detached from the lunchbox. After the clamping assembly 11 swings to the second position, the tearing force applied to the sealing film 9 tends to stabilize, and at this time, the proportion of the portion of the sealing film 9 that has detached from the lunchbox has increased, so the film can be torn off smoothly. Finally, after the sealing film 9 has completely detached from the lunchbox 4, the tearing force disappears, and the clamping assembly 11 swings from the second position to the first position, completing the film tearing. Therefore, it can be seen that the lunchbox film tearing device 100a in this embodiment can achieve film tearing of the sealed lunchbox and ensures smooth film tearing.

[0069] As an example, in the initial state, the clamping component is in Figure 1 , Figure 2 and Figure 6 The first position is shown. At this time, the motion component 10 can drive the clamping component 11 to move to a suitable position for clamping operation. After the clamping component 11 clamps the sealing film 9, the motion component 10 can drive the clamping component 11 to move and start tearing the film. In the early stage of tearing, under the action of the swing connecting component 12, the clamping component 11 can swing relative to the output end of the motion component 10 along the S-direction around the first straight line 13a to the second position, so that the tearing force increases gradually, effectively protecting the integrity of the sealing film 9 and ensuring smooth tearing.

[0070] In some implementation methods, please refer to Figure 5 The swing connection assembly 12 includes a bearing seat 1201, a bearing 1202, a rotating shaft 1203, and an elastic connector 1204.

[0071] Bearing housing 1201 is fixed to the output end of motion assembly 10, and bearing 1202 is housed within bearing housing 1201. Rotating shaft 1203 is connected to bearing housing 1201 via bearing 1202, and rotating shaft 1203 can rotate relative to bearing housing 1201 about a first straight line 13a, where the first straight line 13a is its own axis. Furthermore, rotating shaft 1203 is fixed to clamping assembly 11, thereby allowing clamping assembly 11 to rotate relative to the output end of motion assembly 10 about the first straight line 13a. It is also understood that motion assembly 10 can drive clamping assembly 11 to move.

[0072] One end of the elastic connector 1204 is connected to the output end of the motion component 10, and the other end is connected to the clamping component 11. Due to the action of the elastic connector 1204, in the early stage of film tearing, the clamping component 11 can smoothly swing to the second position relative to the output end of the motion component 10 around the first straight line 13a in the S direction, so that the tearing force changes smoothly. After the film tearing is completed, under the action of the elastic connector 1204, the clamping component 11 can also rotate back to the first position relative to the output end of the motion component 10 around the first straight line 13a in the N direction, so as to clamp the sealing film 9 for the next time.

[0073] In one implementation, the elastic connector 1204 can be a tension spring. Please refer to [reference needed]. Figures 2 to 5 The swing connection assembly 12 includes a first fixed connector 1205 and a second fixed connector 1206. One end of the first fixed connector 1205 is fixed to the output end of the motion assembly 10, and the other end of the first fixed connector 1205 is fixed to one end of the elastic connector 1204. One end of the second fixed connector 1206 is fixed to the clamping assembly 11, and the other end of the second fixed connector 1206 is fixed to the other end of the elastic connector 1204. When the clamping assembly 11 is in position... Figure 1 and Figure 6 In the first position shown, the elastic connector 1204 is stretched to the minimum, while when the clamping assembly 11 is in... Figure 9 and Figure 10 In the first position shown, the elastic connector 1204 is stretched to its maximum extent. Therefore, during the oscillation process, the elastic connector 1204 acts as a resistance, resulting in a more stable oscillation and thus a more stable change in tearing force. It can be understood that after the film is torn off, the clamping assembly 11 can rotate along the N direction to return to the first position under the reset action of the elastic connector 1204, making it more convenient to use.

[0074] In some examples, please refer to Figure 4As shown, there are two elastic connectors 1204, which are symmetrically arranged about the center of the first straight line 13a. The two elastic connectors 1204 are a first elastic connector 1204a and a second elastic connector 1204b. Because the two elastic connectors 1204 are symmetrically arranged about the first straight line 13a, the upper end of the first elastic connector 1204a is connected to the first fixed connector 1205, and the lower end of the first elastic connector 1204a is connected to the second fixed connector 1206. The lower end of the second elastic connector 1204b is connected to the first fixed connector 1205, and the upper end of the second elastic connector 1204b is fixed to the second fixed connector 1206.

[0075] It should be noted that in other embodiments, the elastic connector 1204 can also be other structures, which can be set according to the actual situation, and will not be described in detail here.

[0076] As one implementation method, please refer to Figures 2 to 5 ,as well as Figure 10 As shown, the clamping assembly 11 has a first limiting hole 11011. The first limiting hole 11011 can be an arc-shaped hole, and if this arc-shaped hole is regarded as an arc-shaped cylinder, the axis of the first limiting hole 11011 is located on the first straight line 13a. The swing connection assembly 12 also includes a swing limiting member 1207. One end of the swing limiting member 1207 is fixed to the output end of the motion assembly 10, and the other end of the swing limiting member 1207 is slidably connected in the first limiting hole 11011. When the clamping assembly 11 can rotate around the first straight line 13a relative to the output end of the motion assembly 10, since the swing limit member 1207 is slidably connected in the first limit hole 11011, the first limit hole 11011 can limit the extreme movement position of the swing limit member 1207. That is to say, the first limit hole 11011 can limit the extreme swing angle of the clamping assembly 11. It can not only accurately and effectively limit the swing of the clamping assembly 11 between the first position and the second position, but also effectively protect the elastic connector 1204 and prevent the elastic connector 1204 from being overstretched and failing. This not only improves the stability of the overall structure, but also extends the service life of the elastic connector 1204.

[0077] As an example, please refer to Figure 10As shown, the first limiting hole 11011 has a first end 110111 and a second end 110112 that are disposed opposite to each other. When the swing limiting member 1207 is located at the first end 110111 of the first limiting hole 11011, the clamping assembly 11 is exactly in the first position, and the elastic connector 1204 is in the natural state. When the clamping assembly 11 rotates relative to the output end of the motion assembly 10 along the S-direction to the second position, the first limiting hole 11011 also rotates relative to the swing limiting member 1207. When the clamping assembly 11 rotates to the second position, the swing limiting member 1207 is exactly located at the second end 110112 of the first limiting hole 11011. At this time, the elastic connector 1204 is in a stretched state, but the elastic connector 1204 has not reached the limit of stretching. Therefore, the swing limiting member 1207 can effectively limit the swing angle of the clamping assembly 11, thereby effectively protecting the elastic connector 1204 and preventing the elastic connector 1204 from being overstretched and failing.

[0078] As an example, please refer to Figure 4 , Figure 5 and Figure 10 As shown, the swing connection assembly 12 may include two swing limiting members 1207, which are symmetrically arranged about the center of the first straight line 13a. The first limiting holes 11011 correspond one-to-one with the swing limiting members 1207. When one swing limiting member 1207 is located at the first end 110111 of the corresponding first limiting hole 11011, the other swing limiting member 1207 is also located at the first end 110111 of the corresponding first limiting hole 11011. When the clamping assembly 11 rotates relative to the output end of the motion assembly 10, the two first limiting holes 11011 also rotate relative to the corresponding swing limiting members 1207 until the clamping assembly 11 rotates to the second position, at which point the two swing limiting members 1207 are exactly located at the second end 110112 of the corresponding first limiting hole 11011, thereby further improving the motion stability of the clamping assembly 11.

[0079] In some examples, please refer to Figure 4 and Figure 5 The swing limiter 1207 is a rod-shaped structure parallel to the first straight line 13a. It is understood that in other embodiments, the swing limiter 1207 may also be other structures, which can be set according to the actual situation, and will not be described in detail here.

[0080] In some implementation methods, please refer to Figure 2 , Figure 3 and Figure 5The food container film-tearing device 100a also includes a fixing component 14, which connects the output end of the motion component 10 and the swing connection component 12. The fixing component 14 includes a first fixing plate 1401 and a second fixing plate 1402. The first fixing plate 1401 is fixed to the output end of the motion component 10 and is parallel to the XY plane. The second fixing plate 1402 connects the first fixing plate 1401 and the swing connection component 12, and a first straight line 13a is perpendicular to the second fixing plate 1402. The second fixing plate 1402 is perpendicular to the XY plane and has an angle with the XZ plane. Furthermore, the angle between the second fixing plate 1402 and the XZ plane is adjustable, allowing for more convenient use by adjusting the angle according to actual conditions.

[0081] As one implementation method, please refer to Figure 2 , Figure 3 and Figure 5 The second fixing plate 1402 and the first fixing plate 1401 are detachably fixed by a first fastener (not shown) and a second fastener (not shown). The first fastener and the second fastener can be threaded components such as screws. The first fixing plate 1401 may have a first mounting hole 14011 that mates with the first fastener and a second mounting hole 14012 that mates with the second fastener. The first mounting hole 14011 can be an arc-shaped hole, and the second mounting hole 14012 can be a round hole. The first mounting hole 14011 and the second mounting hole 14012 are coaxially arranged. The threaded part of the first fastener and the threaded part of the second fastener can pass through the corresponding first mounting hole 14011 and the second mounting hole 14012 respectively and be screwed into the second fixing plate 1402, thereby fixing the second fixing plate 1402 to the first fixing plate 1401. When the angle needs to be adjusted, the first fastener can be removed, and then the second fixing plate 1402 can be rotated relative to the first fixing plate 1401 around the second straight line 13b. The second straight line 13b is parallel to the Z-direction, and the axis of the second mounting hole 14012 is the second straight line 13b. After rotating the second fixing plate 1402 to the desired position, the threaded part of the first fastener can be passed through the first mounting hole 14011 and screwed into the second fixing plate 1402 to fix the second fixing plate 1402 and the first fixing plate 1401, which facilitates the adjustment of the angle and makes it more convenient to use.

[0082] In this embodiment, the bearing seat 1201, the swing limiting member 1207 and the first fixed connecting member 1205 can be fixed to the second fixed plate 1402. That is, the clamping assembly 11 is connected to the second fixed plate 1402 through the swing connecting assembly 12, so that the swing connecting assembly 12 can be rotated around the second straight line 13b according to actual needs.

[0083] As an example, please refer to Figure 2 , Figure 3 and Figure 5 The first fixing plate 1401 may have two first mounting holes 14011, which are coaxially arranged. Accordingly, the first fixing plate 1401 and the second fixing plate 1402 can be fastened by two first fasteners, wherein each first mounting hole 14011 cooperates with one first fastener, further improving the connection reliability between the first fixing plate 1401 and the second fixing plate 1402.

[0084] In some implementation methods, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 10 The clamping assembly 11 includes a base 1101, a first clamping member 1102, a second clamping member 1103, and a first driving member 1104. The base 1101 is connected to the swing connection assembly 12, meaning that the rotating shaft 1203 and the second fixed connection member 1206 can be fixed to the base 1101, and a first limiting hole 11011 can be formed in the base 1101. The first clamping member 1102 is slidably connected to the base 1101 and has a first clamping portion 11021. The second clamping member 1103 is disposed on the base 1101 and has a second clamping portion 11031, which is located above the first clamping portion 11021. The second clamping portion 11031 can cooperate with the first clamping portion 11021 to clamp the sealing film 9. The first driving member 1104 is disposed on the base member 1101. The first driving member 1104 can be used to drive the first clamping member 1102 to move so that the first clamping part 11021 is close to the second clamping part 11031, thereby clamping the sealing film 9 between the first clamping part 11021 and the second clamping part 11031. The structure is simple and easy to use.

[0085] As one implementation method, please refer to Figure 2 , Figure 3 and Figure 5 The first clamping part 11021 may have a first clamping surface 110211, which faces the second clamping part 11031. The second clamping part 11031 may have a second clamping surface (not shown), which faces the first clamping part 11021. The first clamping surface 110211 and the second clamping surface can cooperate with each other to clamp the sealing film 9.

[0086] As an example, please refer to Figure 2 , Figure 3 and Figure 5The first clamping surface 110211 can be formed with anti-slip texture, which can be set according to the actual situation, and will not be elaborated here.

[0087] As one implementation method, please refer to Figure 2 and Figure 5 The clamping assembly 11 may further include a first slide rail 1105 and a first slider 1106. The first slide rail 1105 is fixed to the base 1101, and when the clamping assembly 11 is in the first position, the first slide rail 1105 extends along the Z-direction. The first slider 1106 is fixed to the first clamping member 1102, and the first slider 1106 is slidably connected to the first slide rail 1105. In the initial state, the clamping assembly 11 is in the first position, meaning that under the drive of the first drive member 1104, the first clamping member 1102 can move upwards along the Z-direction relative to the base 1101, so that the first clamping part 11021 moves closer to the second clamping part 11031 along the Z-direction.

[0088] It should be noted that in other embodiments, the clamping assembly 11 can also have other structures. For example, the first clamping member 1102 can also move in other directions to bring the first clamping portion 11021 closer to the second clamping portion 11031. Alternatively, the first clamping member 1102 can remain stationary while the second clamping member 1103 moves to bring the second clamping portion 11031 closer to the first clamping portion 11021. Alternatively, the first clamping member 1102 and the second clamping member 1103 can move separately, thereby allowing the first clamping portion 11021 and the second clamping portion 11031 to move toward each other.

[0089] In some implementation methods, please refer to Figure 2 , Figure 5 and Figure 10The second clamping member 1103 is slidably connected to the base member 1101, and the sliding direction of the second clamping member 1103 is parallel to the sliding direction of the first clamping member 1102. The clamping assembly 11 also includes a first limiting member 1107 and a second limiting member 1108, with the second limiting member 1108 spaced below the first limiting member 1107, and the second clamping member 1103 restricted between the first limiting member 1107 and the second limiting member 1108. The first limiting member 1107 includes a fixing part 11071 and an elastic limiting part 11072. The fixing part 11071 is fixed to the base member 1101, the elastic limiting part 11072 is compressed between the second clamping member 1103 and the fixing part 11071, and the second limiting member 1108 is fixed to the base member 1101. When the first clamping member 1102 does not apply any external force directly or indirectly to the second clamping member 1103, the compressed elastic limiting part 11072 will exert a downward pushing force on the second clamping member 1103 due to the reset effect of the elastic limiting part 11072. When the first clamping part 11021 moves to cooperate with the second clamping part 11031 to clamp the sealing film 9, the first clamping part 11021 will exert an upward pushing force on the second clamping part 11031, thereby pushing the first clamping part 11021 to move upward. Under the elastic action of the compressed elastic limiting part 11072, the second clamping part 11031 is abutted against the first clamping part 11021, thereby realizing the elastic clamping of the sealing film 9. This can avoid the inability of the first clamping part 11021 and the second clamping part 11031 to effectively cooperate to clamp the sealing film 9 due to various process errors.

[0090] In one embodiment, the elastic limiting part 11072 can be a compression spring. It should be noted that in other embodiments, the elastic limiting part 11072 can also be other structures, which can be set according to the actual situation, and will not be described in detail here.

[0091] As one implementation method, please refer to Figure 2 , Figure 3 and Figure 5 The clamping assembly 11 may further include a second slide rail 1109 and a second slider 1110. The second slide rail 1109 is fixed to the base 1101 and is parallel to the first slide rail 1105. That is, when the clamping assembly 11 is in the first position, the second slide rail 1109 extends along the Z-direction. The second slider 1110 is fixed to the second clamping member 1103 and is slidably connected to the second slide rail 1109.

[0092] As one implementation method, please refer to Figure 2 , Figure 5 and Figure 10The first clamping member 1102 may further include a first pressure plate portion 11022 and a first vertical arm 11023, wherein the first pressure plate portion 11022 is fixed to the first slider member 1106, the first vertical arm 11023 is fixed to the lower end of the first pressure plate portion 11022, and the first clamping portion 11021 is fixed to the lower end of the first vertical arm 11023. The second clamping member 1103 may further include a second pressure plate portion 11032, a second vertical arm 11033, and a second bending arm 11034. The second pressure plate portion 11032 is fixed to the second slider member 1110. The second vertical arm 11033 is fixed to the lower end of the second pressure plate portion 11032. The second bending arm 11034 is fixed to the lower end of the second vertical arm 11033 and extends obliquely towards the first vertical arm 11023. The second clamping portion 11031 is fixed to the lower end of the second bending arm 11034, thereby allowing the second clamping portion 11031 to be located above the first clamping portion 11021. This embodiment can effectively reduce the width of the clamping assembly 11, which is more conducive to the miniaturization of the lunchbox film-tearing device 100a.

[0093] In some implementation methods, please refer to Figure 3 The first limiting member 1107 also includes a guide portion 11073. One end of the guide portion 11073 is fixed to the fixing portion 11071, and the other end of the guide portion 11073 is movably inserted into the second clamping member 1103. The elastic limiting portion 11072 is sleeved on the guide portion 11073. Furthermore, the extending direction of the guide portion 11073 is parallel to the moving direction of the second clamping member 1103. That is, the guide portion 11073 can make the compression direction and the reset direction of the elastic limiting portion 11072 parallel to the moving direction of the second clamping member 1103, thereby improving the stability of the elastic limiting portion 11072. When the second clamping member 1103 moves upward under the action of the first clamping member 1102, the guide portion 11073 and the fixing portion 11071 remain fixed, and the second clamping member 1103 can move relative to the guide portion 11073, so that the elastic limiting portion 11072 is compressed along the path restricted by the guide portion 11073.

[0094] As one implementation method, please refer to Figure 3 The first limiting member 1107 may include two guide portions 11073 and two elastic limiting portions 11072. The guide portions 11073 and the elastic limiting portions 11072 are arranged in a one-to-one correspondence. Furthermore, the two guide portions 11073 are symmetrically arranged about the second clamping member 1103, which can make the second clamping member 1103 more balanced in terms of force, thereby enabling the first clamping member 1102 and the second clamping member 1103 to keep clamping the sealing film 9.

[0095] In some implementation methods, please refer to Figure 10The first limiting member 1107 may further include a fixed limiting part 11074, which is fixed to the fixed part 11071, and the lower end of the fixed limiting part 11074 protrudes from the lower surface of the fixed part 11071. When the second clamping member 1103 moves upward to abut against the fixed limiting part 11074, the second clamping member 1103 will be unable to continue moving upward. Therefore, the fixed limiting part 11074 can effectively limit the extreme position of the upward movement of the second clamping member 1103, avoid the elastic limiting part 11072 being over-compressed, and also avoid the second clamping member 1103 moving too upward, which would prevent it from effectively cooperating with the first clamping member 1102 to clamp the sealing film 9.

[0096] In some implementation methods, please refer to Figure 11 The sealing film 9 has a locking hole 903. The first clamping member 1102 also includes a locking part 11024, which protrudes from the side of the first clamping part 11021 facing the second clamping part 11031. The locking part 11024 is inserted into the locking hole 903, which can improve the reliability of the clamping assembly 11 and the sealing film 9 and prevent the sealing film 9 from coming out between the first clamping member 1102 and the second clamping member 1103 when the film is torn.

[0097] In one embodiment, a clearance hole (not shown in the figure) may be provided on the second clamping part 11031. The clearance hole may be provided corresponding to the locking part 11024, thereby avoiding the locking part 11024 and preventing the locking part 11024 from interfering with the second clamping part 11031, which would cause the first clamping part 11021 and the second clamping part 11031 to be unable to cooperate in clamping the sealing film 9.

[0098] As an example, in order to effectively remove the sealing film 9, the lunchbox film tearing device 100a can be used in conjunction with the lunchbox clamping device 100b. Please refer to [reference needed]. Figures 6 to 9 After the lunchbox clamping device 100b clamps the edge of the lunchbox 4, the lunchbox film tearing device 100a can be used to tear off the sealing film 9. The sealing film 9 includes an integral body 901 and a tearing part 902. The middle part of the body 901 may have a transparent window. The tearing part 902 protrudes from the edge of the body 901, and a locking hole 903 is formed on the tearing part 902. The lunchbox clamping device 100b has a first hollowed-out part 1021 and a second hollowed-out part 1022, the first hollowed-out part 1021 and the second hollowed-out part 1022, and the second hollowed-out part 1022 is connected to the first hollowed-out part 1021. The body 901 is exposed in the first hollowed-out part 1021, and the tearing part 902 is exposed in the second hollowed-out part 1022, thereby facilitating the film tearing process performed by the lunchbox film tearing device 100a.

[0099] In this example, the working principle of the food container film tearing device 100a is as follows: In the initial state, the first clamping part 11021 is located above the second hollowed-out part 1022. Please refer to... Figure 6 As shown. After the lunchbox clamping device 100b clamps the edge of the lunchbox 4, the motion component 10 drives the clamping component 11 to move until the second clamping part 11031 is above the sealing film 9. At this time, the second clamping part 11031 can contact the upper surface of the sealing film 9, and the first clamping part 11021 extends into the second cutout 1022 and is located below the sealing film 9, with a gap between the first clamping part 11021 and the sealing film 9. Then, the first driving member 1104 drives the first clamping part 11021 to move upward. During this process, the locking part 11024 gradually inserts into the locking hole 903 until the tear-off part 902 of the sealing film 9 is clamped between the first clamping part 11021 and the second clamping part 11031. Please refer to [reference needed]. Figure 7 and Figure 8 As shown. Then, the motion component 10 drives the clamping component 11 to move along the X, Y, and Z directions, applying a tearing force to the sealing film 9 to remove it. Please refer to... Figure 9 As shown. For example, the clamping assembly 11 can move along a fourth straight line, which makes angles with the X, Y, and Z directions respectively. Specifically, after a tearing force is applied, the clamping assembly 11 swings from a first position to a second position relative to the output end of the motion assembly 10 around a first straight line 13a. After the tearing force disappears, the clamping assembly 11 swings back from the second position to the first position.

[0100] In some implementation methods, please refer to Figure 5 The first driving member 1104 includes a first driving part 11041, a first transmission screw part 11042, and a first output part 11043. The first driving part 11041 is connected to the base member 1101, and the first transmission screw part 11042 is connected to the output end of the first driving part 11041. The first output part 11043 is drively connected to the first transmission screw part 11042, and is fixed to the first clamping member 1102. The first driving part 11041 drives the first transmission screw part 11042 to rotate around a third straight line 13c, thereby bringing the first clamping part 11021 closer to the second clamping part 11031. The third straight line 13c is the axis of the first transmission screw part 11042, and is perpendicular to the first straight line 13a.

[0101] As an example, the first drive unit 11041 can be a motor, and the first output unit 11043 can be a lead screw and nut. It should be noted that in other embodiments, the first drive member 1104 can also be other structures, which can be set according to the actual situation, and will not be described in detail here.

[0102] In some implementation methods, please refer to Figure 1The motion component 10 includes three motion modules: a first motion module 1001, a second motion module 1002, and a third motion module 1003. The second motion module 1002 is connected to the output of the first motion module 1001, the third motion module 1003 is connected to the output of the second motion module 1002, and the fixing component 14 is connected to the output of the third motion module 1003. The first motion module 1001 can drive the second motion module 1002 to move along the X-axis, the second motion module 1002 can drive the third motion module 1003 to move along the Y-axis, and the third motion module 1003 can drive the fixing component 14 to move along the Z-axis, thereby enabling the clamping component 11 to move in the X, Y, and Z directions.

[0103] As an example, the motion module can be a linear slide. It should be noted that in other embodiments, the motion module can also have other structures, which can be set as needed, and will not be elaborated here.

[0104] The food vending machine in this application includes the lunchbox tearing device 100a provided in any of the above embodiments.

[0105] In some embodiments, the food vending machine may also include a food container clamping device 100b. Please refer to [reference needed]. Figures 12 to 23 The lunchbox clamping device 100b includes a fixed clamping mechanism 1, a movable clamping mechanism 2, and a first driving mechanism 3. The movable clamping mechanism 2 is located below the fixed clamping mechanism 1 and includes multiple elastic clamping components 201. All elastic clamping components 201 are spaced apart along the edge 401 of the lunchbox 4, and together they support the edge 401 of the lunchbox 4. The first driving mechanism 3 can drive the movable clamping mechanism 2, which supports the lunchbox 4, to move upward to a third position. When the movable clamping mechanism 2 is in the third position, the fixed clamping mechanism 1 abuts against at least a portion of the edge 401 of the lunchbox 4, and each elastic clamping component 201 is independently compressed downward under the action of the fixed clamping mechanism 1, thereby clamping the lunchbox 4.

[0106] In this embodiment, the movable clamping mechanism 2 includes multiple independent elastic clamping components 201. Under the action of the fixed clamping mechanism 1, each elastic clamping component 201 can be independently compressed downward to clamp the corresponding point of the edge 401 of the lunch box 4. Regardless of whether the edge 401 of the lunch box 4 is flat or uneven curved, the movable clamping mechanism 2 in the third position can clamp the edge 401 of the lunch box 4 in cooperation with the fixed clamping mechanism 1. This is not only applicable to the edge 401 of lunch boxes 4 of various shapes, but also can prevent the lunch box 4 from being deformed by clamping. It can also improve the clamping reliability, prevent the lunch box 4 from falling off, and effectively improve the user experience.

[0107] In some implementation methods, please refer to Figure 14 The elastic clamping assembly 201 includes a third clamping member 2011, a fixing member 2012, and an elastic member 2013. The third clamping member 2011 and the fixing member 2012 are vertically arranged sequentially along the direction away from the edge 401 of the lunch box 4. The fixing member 2012 is fixedly connected to the movable clamping mechanism 2. The third clamping member 2011 is used to abut against the lower surface of the edge 401 of the lunch box 4. The elastic member 2013 is sleeved on the fixing member 2012 and abuts against the third clamping member 2011 and the fixing member 2012.

[0108] In this embodiment, under the action of the elastic member 2013, the third clamping member 2011 can abut against the lower surface of the edge 401 of the lunch box 4. Furthermore, the elastic member 2013 of each elastic clamping component 201 can be compressed and reset independently without affecting each other. This effectively ensures that each elastic clamping component 201 can independently compress downward and clamp the corresponding point of the edge 401 of the lunch box 4 under the action of the fixed clamping mechanism 1, thereby firmly clamping the lunch box 4.

[0109] In some implementation methods, please refer to Figure 23 The third clamping member 2011 includes a body 20111 and a plurality of third clamping parts 20112. Each third clamping part 20112 protrudes from the upper end of the body 20111 and abuts against the lower surface of the edge 401 of the lunch box 4. Each elastic clamping assembly 201 may include a plurality of elastic elements 2013 and a plurality of fixing elements 2012. The fixing elements 2012 and the third clamping parts 20112 are arranged in a one-to-one correspondence in the Z direction. The elastic elements 2013 are sleeved on the corresponding fixing elements 2012 and abut against the body 20111 and the corresponding fixing elements 2012. It can be understood that this implementation can enhance the overall structural strength of the elastic clamping assembly 201, so that the elastic clamping assembly 201 can be compressed vertically downward as stably as possible under force, thus improving the reliability of use; at the same time, it increases the contact area between the elastic clamping assembly 201 and the edge 401 of the lunch box 4, thus improving the clamping reliability.

[0110] For example, please refer to Figure 23The third clamping member 2011 includes a body 20111 and two third clamping parts 20112. The two third clamping parts 20112 protrude from the upper end of the body 20111 and are symmetrically arranged about the body 20111. Each third clamping part 20112 abuts against the lower end of the edge 401 of the lunchbox 4. The elastic clamping member includes two fixing members 2012 and two elastic members 2013. The two fixing members 2012 are symmetrically arranged about the third clamping member 2011 and correspond one-to-one with the third clamping parts 20112. The elastic members 2013 are sleeved on the corresponding fixing members 2012 and abut against the body 20111 and the corresponding fixing members 2012. Furthermore, the two third clamping parts 20112 can clamp corresponding points on the edge 401 of the lunchbox 4, further improving clamping reliability.

[0111] In some implementation methods, please refer to Figure 15 The lunchbox 4 is square in shape, and its edge 401 includes four side edges. It should be noted that the term "square" here should be interpreted broadly, meaning that the lunchbox 4 is generally square; simply put, the lunchbox 4 gives the initial impression of being square. The elastic clamping component 201 is correspondingly positioned to at least two of the opposite side edges to ensure reliable clamping. It should be noted that in other embodiments, the lunchbox 4 can also have other shapes, depending on the actual situation, which will not be elaborated upon here.

[0112] As one implementation method, please refer to Figure 15 The four sides include two first sides 4011 and two second sides 4012. The two first sides 4011 are arranged opposite each other in the Y direction, and the two second sides 4012 are arranged opposite each other in the X direction.

[0113] like Figure 14 As shown, in the movable clamping mechanism 2, the elastic clamping component 201 is divided into a first elastic clamping component 201a and a second elastic clamping component 201b. The first elastic clamping component 201a is supported at the lower end of the first side 4011, and the second elastic clamping component 201b is supported at the lower end of the second side 4012. Based on this, the movable clamping mechanism 2 also includes a first movable clamping component 202 and a second movable clamping component 203.

[0114] There is one first movable clamping component 202, which is correspondingly disposed with one of the first side edges 4011. Therefore, the upper end of the first movable clamping component 202 is provided with multiple first elastic clamping components 201a. There are two second movable clamping components 203, which are correspondingly disposed with the two second side edges 4012. Therefore, the upper end of each second movable clamping component 203 is provided with multiple second elastic clamping components 201b. The first movable clamping component 202 is used to position the lunch box 4 in the Y direction, and the two second movable clamping components 203 can move towards each other in the X direction to position the lunch box 4 in the X direction.

[0115] As an example, in use, the first side 4011 of the lunchbox 4 can be placed on the first elastic clamping component 201a to position the lunchbox 4 in the Y direction. Then, the two second movable clamping components 203 are moved towards each other in the X direction until the two second sides 4012 of the lunchbox 4 are placed on the corresponding second elastic clamping components 201b, thereby positioning the lunchbox 4 in the X direction. Please refer to [reference needed]. Figure 15 Then, the movable clamping mechanism 2, which supports the lunchbox 4, is driven to move upward to the third position, so that the fixed clamping mechanism 1 and the movable clamping mechanism 2 cooperate to clamp the edge 401 of the lunchbox 4. Please refer to [the relevant documentation]. Figures 16 to 20 .

[0116] In this embodiment, the structure of the first elastic clamping component 201a and the structure of the second elastic clamping component 201b can be the same. The following description takes the first elastic clamping component 201a as an example.

[0117] In some examples, please refer to Figure 23 The first movable clamping assembly 202 has guide holes 2021 that correspond one-to-one with the fixing members 2012. The fixing member 2012 includes an integral rod portion 20121 and a flange portion 20122, with the flange portion 20122 protruding from the lower end of the rod portion 20121. The upper end of the rod portion 20121 passes through the guide holes 2021 and is fixed to the third clamping member 2011, while the flange portion 20122 is confined outside the guide holes 2021. The elastic member 2013 is sleeved on the rod portion 20121 and compressed between the third clamping member 2011 and the first movable clamping assembly 202. In this example, the fastener 2012 can also guide the third clamping member 2011, so that the third clamping member 2011 can move more stably along the Z direction, thereby making the structure of the first elastic clamping assembly 201a more stable and able to clamp the corresponding points of the edge 401 of the lunch box 4 more stably and effectively.

[0118] In one example, please refer to Figure 14 and Figure 23The first elastic clamping assembly 201a may also include a sleeve 2014, which is confined within the guide hole 2021 and sleeved outside the rod 20121, thereby effectively reducing the friction between the rod 20121 and the first movable clamping assembly 202 and extending the service life of the first movable clamping assembly 202.

[0119] It should be noted that in other embodiments, the first elastic clamping component 201a and the second elastic clamping component 201b may have other structures, and the structures of the first elastic clamping component 201a and the second elastic clamping component 201b may also be different, which can be set according to the actual situation, and will not be elaborated here.

[0120] In some implementation methods, please refer to Figure 14 , Figure 15 and Figure 20 The movable clamping mechanism 2 also includes a positioning component 204. The positioning component 204 can be provided on the first movable clamping component 202, and the positioning component 204 can also be provided on the second movable clamping component 203. The fixed clamping mechanism 1 has a positioning hole 101, which is inserted and engaged with the corresponding positioning component 204.

[0121] When the movable clamping mechanism 2 moves to the third position, the positioning component 204 is inserted into the corresponding positioning hole 101. Furthermore, the positioning component 204 on the first movable clamping component 202 can abut against the edge of the lunch box 4 in the Y direction, and the positioning component 204 on the second movable clamping component 203 can abut against the edge of the lunch box 4 in the X direction. This not only improves the coordination accuracy between the movable clamping mechanism 2 and the fixed clamping mechanism 1, allowing the movable clamping mechanism 2 and the fixed clamping mechanism 1 to more effectively cooperate in clamping the edge 401 of the lunch box 4, but also improves the positioning accuracy of the lunch box 4 on the lunch box clamping device 100b.

[0122] As one implementation method, please refer to Figure 15 as well as Figures 20 to 22The positioning component 204 is divided into a first positioning component 204a and a second positioning component 204b, and the positioning hole 101 is divided into a first positioning hole 101a and a second positioning hole 101b. The first positioning component 204a is fixed to the upper end of the first movable clamping component 202, and the first movable clamping component 202 has two first positioning components 204a arranged symmetrically in the X-direction. The fixed clamping mechanism 1 has first positioning holes 101a that correspond to and engage with the first positioning components 204a. The second positioning component 204b is fixed to the upper end of the second movable clamping component 203, and each second movable clamping component 203 has two second positioning components 204b arranged symmetrically in the Y-direction. The fixed clamping mechanism 1 has second positioning holes 101b that correspond to and engage with the second positioning components 204b. This embodiment not only further improves the coordination accuracy between the movable clamping mechanism 2 and the fixed clamping mechanism 1, but also allows the first positioning component 204a to reliably position the lunch box 4 in the Y direction and the second positioning component 204b to reliably position the lunch box 4 in the X direction, further improving the positioning accuracy of the lunch box 4 on the lunch box clamping device 100b, and making it easier to perform precise operations such as tearing the film in the subsequent process.

[0123] As an example, please refer to Figure 20 The second positioning hole 101b can be an elongated hole that passes through the fixed clamping mechanism 1 along the Z direction, and the second positioning hole 101b extends along the X direction, so that the lunch box clamping device 100b can be used to clamp lunch boxes 4 of different sizes, making it more flexible to use.

[0124] In some implementation methods, please refer to Figures 12 to 22 The lunchbox clamping device 100b also includes a frame 5, a first sliding connection mechanism 6, a second sliding connection mechanism 7, and a second drive mechanism 8. The fixed clamping mechanism 1 is fixed to the frame 5. The first sliding connection mechanism 6 is used to slide the first movable clamping assembly 202 and the frame 5. Under the action of the first sliding connection mechanism 6, the first movable clamping assembly 202 can move relative to the frame 5 along the Z-direction. There are two second sliding connection mechanisms 7, each corresponding to one of the two second movable clamping assemblies 203. Each second sliding connection mechanism 7 is used to slide the corresponding second movable clamping assembly 203 and the frame 5. Under the action of the second sliding connection mechanism 7, the second movable clamping assembly 203 can move relative to the frame 5 along the Z-direction and the X-direction. The second drive mechanism 8 is mounted on the frame 5. The second drive mechanism 8 can be used to drive the two second movable clamping components 203 to move towards each other in the X direction, thereby positioning the lunch box 4 in the X direction. The second drive mechanism 8 can also be used to drive the two second movable clamping components 203 to move away from each other in the X direction, thereby releasing the lunch box 4.

[0125] In this embodiment, a single second drive mechanism 8 can simultaneously drive two second movable clamping components 203 to move towards or away from each other in the X direction. This results in a simpler structure, reduces the number of drive mechanisms, lowers the structural complexity of the lunchbox clamping device 100b, and also reduces the space occupied by the lunchbox clamping device 100b, making it easier to miniaturize the lunchbox clamping device 100b.

[0126] As one implementation method, please refer to Figures 12 to 22 The second drive mechanism 8 includes a third drive member 801, a second transmission screw member 802, and a second output member 803. The third drive member 801 is fixed to the frame 5, and the second transmission screw member 802 is fixed to the output end of the third drive member 801. There are two second output members 803, each corresponding to one of the two second sliding connection mechanisms 7. One end of the second output member 803 in the Y direction is connected to the second transmission screw member 802, and the other end of the second output member 803 in the Y direction is fixed to the corresponding second sliding connection mechanism 7. The third drive member 801 can drive the second transmission screw member 802 to rotate around the second axis, so that the two second output members 803 move towards each other or away from each other in the X direction, thereby driving the two second movable clamping assemblies 203 to move towards each other or away from each other through the two second sliding connection mechanisms 7. The second axis is the axis of the second transmission screw member 802 itself, and the second axis is parallel to the X direction.

[0127] As an example, the third driving component 801 can be a motor, and the second output component 803 can be a lead screw and nut. It should be noted that in other embodiments, the second driving mechanism 8 can also be other structures, which can be set according to the actual situation, and will not be described in detail here.

[0128] As one implementation method, please refer to Figure 12 , Figure 14 , Figure 15 , Figure 17 and Figure 22 The first sliding connection mechanism 6 includes a third slide rail 601 and a third slider 602. The third slide rail 601 is fixed to the frame 5 and extends along the Z-direction. The third slider 602 is fixed to the first movable clamping assembly 202 and slidably connected to the third slide rail 601. Under the action of the first driving mechanism 3, the third slider 602 can slide along the Z-direction on the third slide rail 601, thereby achieving a sliding connection between the first movable clamping assembly 202 and the frame 5 in the Z-direction.

[0129] As one implementation method, please refer to Figure 12 , Figure 14 , Figure 15 , Figure 17and Figure 22 The second sliding connection mechanism 7 includes a fourth slide rail 701, a fourth slider 702, a connecting plate 703, a fifth slide rail 704, and a fifth slider 705. The fourth slide rail 701 is fixed to the frame 5 and extends along the X-direction. The fourth slider 702 is slidably connected to the fourth slide rail 701 and is fixedly connected to the fifth slide rail 704 via the connecting plate 703. The fifth slide rail 704 extends along the Z-direction. The fifth slider 705 is fixed to the second movable clamping assembly 203 and is slidably connected to the fifth slide rail 704. In this embodiment, the second output component 803 of the second drive mechanism 8 is fixed to the connecting plate 703. Under the action of the second drive mechanism 8, the fourth slider 702 can move along the X-direction on the fourth slide rail 701, thereby achieving a sliding connection between the second movable clamping assembly 203 and the frame 5 in the X-direction. Under the action of the first drive mechanism 3, the fifth slider 705 can slide along the Z direction on the fifth slide rail 704, thereby realizing the sliding connection between the second movable clamping assembly 203 and the frame 5 in the Z direction.

[0130] In some implementation methods, please refer to Figure 12 and Figure 14 A first driving mechanism 3 is mounted on the frame 5. The first driving mechanism 3 can drive the first movable clamping assembly 202 and the second movable clamping assembly 203 to move synchronously in the Z-axis. The output end of the first driving mechanism 3 is connected to the first movable clamping assembly 202. The movable clamping mechanism 2 also includes a limiting assembly 205, which includes a third limiting member 2051 and two fourth limiting members 2052. The third limiting member 2051 is fixed to the first movable clamping assembly 202. The fourth limiting members 2052 are correspondingly arranged with the second movable clamping assemblies 203, each fourth limiting member 2052 being fixed to its corresponding second movable clamping assembly 203. Furthermore, each fourth limiting member 2052 is slidably connected to the third limiting member 2051 in the X-axis, and each fourth limiting member 2052 can slide relative to the third limiting member 2051 in the X-axis.

[0131] In this embodiment, the movable clamping mechanism 2 further includes a limiting component 205. Under the action of the limiting component 205, the second movable clamping component 203 can slide relative to the first movable clamping component 202 in the X direction. Furthermore, under the action of the limiting component 205, when the first driving mechanism 3 drives the first movable clamping component 202 to move in the Z direction, the second movable clamping component 203 can also move along the Z direction with the first movable clamping component 202. Using only one first driving mechanism 3 can drive the first movable clamping component 202 and the second movable clamping component 203 to move synchronously in the Z direction, resulting in a simpler structure, reduced driving mechanisms, and reduced structural complexity of the lunchbox clamping device 100b. It also reduces the space occupied by the lunchbox clamping device 100b, making it more suitable for miniaturization.

[0132] As one implementation method, please refer to Figure 18 The third limiting member 2051 can be a plate-like structure extending along the X direction. Two second limiting holes 20511 symmetrically arranged in the X direction are provided on the third limiting member 2051. The second limiting holes 20511 are constructed as elongated holes extending along the X direction. The fourth limiting member 2052 is a pulley rotatably connected to the second movable clamping assembly 203, and the fourth limiting member 2052 is slidably connected within the corresponding second limiting hole 20511. Because the second limiting hole 20511 is an elongated hole extending along the X direction, the second movable clamping assembly 203 can move relative to the first movable clamping assembly 202 along the X direction, but the second movable clamping assembly 203 cannot move relative to the first movable clamping assembly 202 in other directions. Therefore, when the first driving mechanism 3 drives the first movable clamping component 202 to move in the Z direction, the second movable clamping component 203 will move synchronously in the Z direction with the first movable clamping component 202. This simplifies the structure, reduces the number of driving mechanisms, and lowers the structural complexity of the lunchbox clamping device 100b. When the second movable clamping component 203 moves relative to the first movable clamping component 202 in the X direction, the first movable clamping component 202 remains stationary in the X direction. The fourth limiting member 2052 can slide relative to the third limiting member 2051 within the second limiting hole 20511. This not only allows the second movable clamping component 203 to move more smoothly relative to the first movable clamping component 202 in the X direction, but also effectively reduces the friction between the third limiting member 2051 and the fourth limiting member 2052, extending the service life of the limiting component 205.

[0133] As one implementation method, please refer to Figure 14The first driving mechanism 3 includes a second driving member 301, a first transmission screw 302, and a first output member 303. The second driving member 301 is fixed to the frame 5, and the first transmission screw 302 is fixed to the output end of the second driving member 301. The first output member 303 is drively connected to the first transmission screw 302 and is fixed to the first movable clamping assembly 202. The second driving member 301 can drive the first transmission screw 302 to rotate around a first axis, so that the first movable clamping assembly 202 and the second movable clamping assembly 203 move synchronously in the Z direction. The first axis is the axis of the first transmission screw 302 itself and is parallel to the Z direction.

[0134] As an example, the second driving component 301 can be a motor, and the first output component 303 can be a lead screw and nut. It should be noted that in other embodiments, the first driving mechanism 3 can also be other structures, which can be set according to the actual situation, and will not be elaborated here.

[0135] As an example, the working principle of the lunchbox clamping device 100b is as follows: After the first side 4011 of the lunchbox 4 is placed on the first elastic clamping component 201a and the edge of the lunchbox 4 abuts against the first positioning component 204a in the Y direction, the second driving mechanism 8 drives the two second movable clamping components 203 to move towards each other in the X direction relative to the first movable clamping component 202, until the two second side 4012 of the lunchbox 4 are placed on the corresponding second elastic clamping components 201b and the edge of the lunchbox 4 abuts against the second positioning component 204b in the X direction. Please refer to [reference needed]. Figure 15 As shown. Then, the first drive mechanism 3 drives the first movable clamping assembly 202 and the second movable clamping assembly 203, which jointly support the lunch box 4, to move upward synchronously to the third position, so that the fixed clamping mechanism 1 and the movable clamping mechanism 2 cooperate to clamp the edge 401 of the lunch box 4. Please refer to... Figures 16 to 20 After other devices complete their processing of the lunchbox 4, such as the movement of the lunchbox clamping device 100b and the tearing of the film by the lunchbox film tearing device 100a, the first drive mechanism 3 drives the first movable clamping assembly 202 and the second movable clamping assembly 203, which jointly support the lunchbox 4, to move downwards synchronously, so that the lunchbox 4 separates from the fixed clamping mechanism 1. Then, the second drive mechanism 8 drives the two second movable clamping assemblies 203 to move in opposite directions along the X direction to release the lunchbox 4, so that the lunchbox 4 can be removed from the lunchbox clamping device 100b.

[0136] In some implementation methods, please refer to Figure 15 and Figure 20The fixing clamping mechanism 1 includes a fixing clamping member 102, which is fixed to the frame 5. A positioning hole 101 is formed on the fixing clamping member 102. The fixing clamping member 102 has a hollow structure and also has a first hollow portion 1021 and a second hollow portion 1022. The first hollow portion 1021 and the second hollow portion 1022 respectively penetrate the fixing clamping member 102 along the Z direction, and the second hollow portion 1022 is connected to the first hollow portion 1021. The main body 901 is exposed in the first hollow portion 1021, and the tearing portion 902 is exposed in the second hollow portion 1022, thereby facilitating the film tearing process of the lunch box film tearing device 100a.

[0137] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
