Description

Technical Field

[0001] The present invention relates to an empty bottle and can recycling machine, belonging to the field of empty bottle recycling devices. Background Art

[0002] Plastic bottles are widely used as beverage bottles in today's society. Therefore, the generation rate of empty bottles is very fast and the quantity is large. If the empty bottles are not compressed during the recycling stage, the recycling bags for empty bottles will be filled up quickly, and the replacement frequency of the recycling bags will be very high, resulting in an increase in labor costs and recycling bag costs.

[0003] For this reason, some existing empty bottle recycling machines will first compress the input empty bottles to reduce the space occupied by the empty bottles, and then put the compressed empty bottles into the recycling bags. The empty bottle recycling machine has a feeding port for empty bottles. Since the sizes of different empty bottles are different, the size of the feeding port can only be designed according to the largest specification. After some smaller-sized bottles are put in, they are very likely to tip over and rotate relative to the compression device, directly causing the subsequent lateral partial compression of the empty bottles by the compression device. Therefore, a large part of the empty bottles is still in an uncompressed state after compression, and the stability of the compression result is very poor. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an empty bottle and can recycling machine with more stable compression effect on small empty bottles.

[0005] To solve the above technical problem, the present invention adopts the following technical solutions:

[0006] An empty bottle and can recycling machine includes a machine body and a recycling and compression mechanism. The recycling and compression mechanism is installed on the machine body. The recycling and compression mechanism includes a compression component, a pressing plate component, and a lifting component. The compression component and the pressing plate component cooperate to compress the empty bottle and can. The pressing plate component includes a pressing plate bracket, a first pressing plate door, and a second pressing plate door. A large bottle feeding port is opened on the pressing plate bracket, a small bottle feeding port is opened on the first pressing plate door, and the lifting component drives the first pressing plate door and the second pressing plate door to move to open and close the large bottle feeding port, and the lifting component drives the second pressing plate door to move to open and close the small bottle feeding port.

[0007] The beneficial effects of the present invention are:

[0008] The large bottle feeding port, small bottle feeding port and the second pressing plate door cooperate with each other to determine the opening size for the input of empty bottles. When the size of the empty bottle or can is large, the small bottle feeding port and the second pressing plate door move away from the large bottle feeding port, and the empty bottle or can can directly reach between the compression assembly and the large bottle feeding port from the large bottle feeding port. Then, the second pressing plate door moves to the large bottle feeding port to prevent the empty bottle or can from leaving the large bottle feeding port, and cooperate with the compression assembly to squeeze both ends of the empty bottle or can. When the size of the empty bottle or can is small, the second pressing plate door moves away from the large bottle feeding port, and the small bottle feeding port remains at the large bottle feeding port. The first pressing plate door is used to block a part of the edge of the large bottle feeding port at the edge of the small bottle feeding port. The empty bottle or can can only reach between the small bottle feeding port and the compression assembly from the small bottle feeding port. Then, the second pressing plate door blocks the small bottle feeding port again and cooperates with the compression assembly to compress the empty bottle or can. The large bottle feeding port and the small bottle feeding port are used to guide the entry process of the empty bottle to reduce the rotation of the empty bottle or can during the movement towards the compression assembly, so that the ends of the empty bottle or can are as aligned as possible with the compression assembly and the second pressing plate door during the compression process, improving the stability and compression effect of the compression of the empty bottle or can.

[0009] In the present invention, a first sliding groove is provided on the pressing plate support, the first pressing plate door is slidably arranged at the first sliding groove, a second sliding groove is provided on the first pressing plate door, and the second pressing plate door is slidably arranged at the second sliding groove. The pressing plate support drives the first pressing plate door and the second pressing plate door to approach or move away from the compression assembly simultaneously.

[0010] In the present invention, a first lifting arm is provided on the first pressing plate door, a second lifting arm is provided on the second pressing plate door. Both the second lifting arm and the first lifting arm extend towards the lifting assembly. The length of the second lifting arm is greater than that of the first lifting arm. The lifting assembly drives the first pressing plate door and the second pressing plate door to act through the first lifting arm and the second lifting arm.

[0011] In the present invention, the lifting assembly includes a lifting rod and a lifting power mechanism connected to the lifting rod. The lifting rod raises the first pressing plate door through the first lifting arm and raises the second pressing plate door through the second lifting arm, or the second pressing plate door is supported on the first pressing plate door so that the lifting rod raises the first pressing plate door and the second pressing plate door simultaneously through the first lifting arm.

[0012] In the present invention, the lifting power mechanism includes a lifting gear, a lifting rack and a lifting motor. The lifting rack is fixed relative to the compression assembly. The lifting motor drives the lifting gear to rotate so that the lifting gear moves on the lifting rack. The lifting gear is installed on the lifting rod.

[0013] The recycling and compression mechanism of the present invention further includes a feeding port support assembly. The feeding port support assembly includes a feeding port support and a protection door. A large bottle feeding through port opposite to the large bottle feeding port is provided on the feeding port support. The protection door moves at the large bottle feeding through port to control the opening and closing of the large bottle feeding through port.

[0014] The feeding port bracket assembly of the present invention further includes a guiding and supporting column for guiding and supporting empty bottles and cans during the compression process. The two ends of the guiding and supporting column are respectively fixed on the lower edge of the large bottle feeding opening and the compression assembly.

[0015] The recycling and compression mechanism of the present invention further includes a heating assembly installed on the compression assembly.

[0016] The compression assembly of the present invention includes a compression bracket, and air-permeable holes are provided on the second pressing plate door and / or the compression bracket.

[0017] A storage area is provided inside the machine body of the present invention. A controller and a barcode scanner are provided on the machine body. The barcode scanner and the recycling and compression mechanism are both electrically connected to the controller. A dropping port and a bottle cap feeding port are also provided on the machine body. A bottle cap collection bag and an empty bottle and can collection bag are provided in the storage area. The bottle cap feeding port is communicated with the bottle cap collection bag, and the dropping port is located below the recycling and compression mechanism and is communicated with the empty bottle and can collection bag.

[0054] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0055] In the following description, terms such as "inner", "outer", "upper", "lower", "left", "right", etc. indicating orientation or position relationship are only for convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. Embodiment

[0056] See Figures 1-15 , an empty bottle and can recycling machine, including a machine body 1 and a recycling and compressing mechanism 2.

[0057] The machine body 1 includes a maintenance cabinet door 12, a recycling cabinet door 13, a main body frame 16, and a compressing area 17 arranged above the main body frame 16. A storage area 18 is arranged inside the main body frame 16. The recycling and compressing mechanism 2 is installed on the top of the main body frame 16 so that the recycling and compressing mechanism 2 is accommodated in the compressing area 17. Among them, the maintenance cabinet door 12 is detachably installed at the opening of the compressing area 17. A throwing port 123 is opened on the maintenance cabinet door 12. Users can only throw the empty bottles and cans 3 into the recycling and compressing mechanism 2 through the throwing port 123. The maintenance cabinet door 12 prevents other sundries from entering the compressing area 17 to protect the recycling and compressing mechanism 2. At the same time, it is also convenient for maintenance personnel to repair and replace the recycling and compressing mechanism 2 after the maintenance cabinet door 12 is removed. The top of the main body frame 16 is a main body partition 161. The main body partition 161 separates the compressing area 17 and the storage area 18. A dropping port 163 is arranged on the main body partition 161. The dropping port 163 is located below the recycling and compressing mechanism 2. After the recycling and compressing mechanism 2 compresses the empty bottles and cans 3, the empty bottles and cans 3 enter the storage area 18 under the action of gravity through the dropping port 163. A bottom support 162 is also arranged on the main body partition 161. The dropping port 163 is exposed outside the bottom support 162 to avoid the bottom support 162 affecting the movement of the empty bottles and cans 3 towards the dropping port 163. The main body frame 16 supports the recycling and compressing mechanism 2 through the bottom support 162.

[0058] The recycling cabinet door 13 is installed at the opening of the storage area 18. After the recycling personnel opens the recycling cabinet door 13, the compressed empty bottles and cans 3 in the storage area 18 are recycled. In addition, in this embodiment, a bottle cap delivery port 131 is provided on the recycling cabinet door 13. The user can drop the bottle caps into the storage area 18 through the bottle cap delivery port 131 to collect the bottle caps. Among them, a bottle cap collection bag 182 and an empty bottle and can collection bag 181 are provided in the storage area 18. The empty bottle and can collection bag 181 is connected to the drop port 163. The compressed empty bottles and cans 3 dropped from the drop port 163 enter the empty bottle and can collection bag 181 for collection. The bottle cap delivery port 131 is connected to the bottle cap collection bag 182. The bottle caps enter the bottle cap collection bag 182 through the bottle cap delivery port 131 for collection. The bottle caps and empty bottles and cans 3 are recycled separately to avoid secondary sorting by recycling personnel, improve recycling efficiency, and reduce operating costs.

[0059] An air inlet groove 1112 is provided on the side wall of the compression area 17, and an air outlet groove 1111 is provided on the side wall of the storage area 18. The air inlet groove 1112 and the air outlet groove 1111 enable the body 1 to exchange gas with the outside world to avoid odor inside the body 1 as much as possible.

[0060] The body 1 is provided with a controller 14, an interactive screen 121, and a barcode scanner 122. The interactive screen 121, the barcode scanner 122, and the recycling and compression mechanism 2 are all electrically connected to the controller 14. The barcode scanner 122 reads the barcode on the packaging of the empty bottle can 3. The controller 14 identifies the specification information of the empty bottle can 3 according to the information read by the barcode scanner 122. The controller 14 adjusts and controls the operating parameters of the recycling and compression mechanism 2 according to the specification information of the empty bottle can 3 to reduce the occurrence of over-compression or under-compression of the empty bottle can 3. The interactive screen 121 provides a user assistance option. When the barcode scanner 122 cannot identify or the packaging of the empty bottle can 3 is lost, the controller 14 controls the operating parameters of the recycling and compression mechanism 2 according to the operation information of the interactive screen 121. The controller 14 can also exchange information with the background network through a wireless module.

[0061] In other embodiments, when the controller 14 is directly electrically connected to other devices for interaction, the interactive screen 121 and the barcode scanner 122 may be cancelled.

[0062] In this embodiment, a bottle cap detection device 19 is provided at the bottle cap delivery port 131. After the barcode scanner 122 reads the barcode of the empty bottle can 3 and identifies that the empty bottle can 3 and the bottle cap are separable, the bottle cap detection device 19 detects that the bottle cap is thrown into the bottle cap delivery port 131, and the controller 14 will control the recycling compression mechanism 2 to open the throwing port 123 so that the user can recycle the empty bottle can 3, so as to achieve the purpose of forcing the user to separate the empty bottle can 3 and the bottle cap. If the barcode information of the empty bottle can 3 read by the barcode scanner 122 shows that the empty bottle can 3 and the bottle cap are inseparable, the recycling compression mechanism 2 can directly open the throwing port 123 for the user to throw.

[0063] In addition, before scanning the barcode on the empty bottle can 3, the user can first present the membership code to the scanner 122 for scanning, and then scan the barcode. The controller 14 has a remote transmission module. After the membership code and the barcode are scanned, the controller 14 transmits the corresponding information to the server backend through the remote transmission module. The server backend increases the points of the corresponding member account. The points can be exchanged for rewards, thereby enhancing the user's motivation and enthusiasm for the classified recycling of empty bottles and cans 3 and bottle caps.

[0064] Specifically, the bottle cap detection device 19 includes a detection shell 191, a revolving door 192, a torsion spring 193, a rotating shaft 194 and a detection plate 195. The detection shell 191 is installed in the bottle cap delivery port 131, the bottle cap delivery port 131 is located at the entrance of the detection shell 191, and the outlet of the detection shell 191 is connected to the bottle cap collection bag 182. The detection shell 191 guides the bottle caps so that the bottle caps delivered at the bottle cap delivery port 131 are directly sent to the bottle cap collection bag 182. The detection plate 195 is located at the exit position of the detection shell 191, and the detection plate 195 is electrically connected to the controller 14, and the action of the bottle caps falling into the bottle cap collection bag 182 is monitored by the detection plate 195. The rotating shaft 194 is installed at the entrance of the detection shell 191, and the torsion spring 193 is sleeved on the rotating shaft 194. The two ends of the torsion spring 193 are respectively pressed on the delivery revolving door 192 and the detection shell 191. The delivery revolving door 192 is rotatably installed at the bottle cap delivery port 131 through the rotating shaft 194 to control the opening and closing of the bottle cap delivery port 131. When the bottle cap is delivered at the bottle cap delivery port 131, the delivery revolving door 192 is pushed to rotate into the storage area 18 and the torsion spring 193 is deformed, thereby opening the bottle cap delivery port 131. After the bottle cap is delivered, the delivery revolving door 192 closes the bottle cap delivery port 131 again under the resetting action of the torsion spring 193.

[0065] Preferably, the body 1 also includes a support foot 15 arranged at the bottom of the main frame 16, and the support foot 15 supports the main frame 16 so that a gap is left between the main frame 16 and the ground to prevent the main frame 16 from directly contacting the ground and preventing rust caused by rainwater soaking.

[0066] The recycling and compression mechanism 2 includes a compression assembly 21, a pressing plate assembly 22, a lifting assembly 24, and a feeding port support assembly 23. The feeding port support assembly 23 is located at the throwing port 123 and controls the opening and closing of the throwing port 123. The main body partition 161 is inclined relative to the horizontal plane, and the vertical height of the feeding port support assembly 23 is relatively higher than that of the compression assembly 21. Therefore, after the empty bottles and cans 3 are thrown into the throwing port 123, they will move towards the compression assembly 21 under the action of gravity and inertia. The feeding port support assembly 23 and the compression assembly 21 will not slide on the main body partition 161, and the pressing plate assembly 22 reciprocates between the feeding port support assembly 23 and the compression assembly 21 on the main body partition 161. When compressing the empty bottles and cans 3, the pressing plate assembly 22 and the compression assembly 21 respectively squeeze both ends of the empty bottles and cans 3.

[0067] The pressing plate assembly 22 includes a pressing plate support 221, a first pressing plate door 222, and a second pressing plate door 223. A large bottle feeding port 2212 is provided on the pressing plate support 221, a small bottle feeding port 2222 is provided on the first pressing plate door 222, and the lifting assembly 24 drives the first pressing plate door 222 and the second pressing plate door 223 to move on the pressing plate support 221.

[0068] During the throwing stage of the empty bottles and cans 3, the controller 14 controls the lifting assembly 24 to act, and then the lifting assembly 24 acts on the feeding port support assembly 23 to control the opening of the throwing port 123. At this time, the pressing plate assembly 22 is located at the feeding port support assembly 23. If the size specification of the empty bottles and cans 3 read by the controller 14 in advance is larger than the size of the small bottle feeding port 2222 and smaller than the size of the large bottle feeding port 2212, the lifting assembly 24 will lift the first pressing plate door 222 and the second pressing plate door 223, so that the large bottle feeding port 2212 is completely exposed. At this time, the empty bottles and cans 3 can reach between the pressing plate assembly 22 and the compression assembly 21 from the throwing port 123 through the large bottle feeding port 2212; if the size specification of the empty bottles and cans 3 read by the controller 14 in advance is smaller than the size of the small bottle feeding port 2222, the lifting assembly 24 will lift the second pressing plate door 223. The small bottle feeding port 2222 is still in the middle of the large bottle feeding port 2212 under the action of gravity, and the part of the first pressing plate door 222 located at the edge of the small bottle feeding port 2222 covers the edge of the large bottle feeding port 2212. At this time, the empty bottles and cans 3 can reach between the pressing plate assembly 22 and the compression assembly 21 from the throwing port 123 through the large bottle feeding port 2212 and the small bottle feeding port 2222.

[0069] During the compression stage of the empty bottle or can 3, the throwing opening 123 is closed, and the lifting component 24 does not lift the first pressing plate door 222 and the second pressing plate door 223. Under the action of their own weights, the first pressing plate door 222 and the second pressing plate door 223 are both in the middle of the large bottle feeding opening 2212. The second pressing plate door 223 blocks the small bottle feeding opening 2222, and the second pressing plate door 223 and the first pressing plate door 222 cooperate to block the large bottle feeding opening 2212. During the extrusion process of the empty bottle or can 3, both ends are respectively abutted against the second pressing plate door 223 and the compression component 21. The second pressing plate door 223 moves towards the compression component 21 to compress the empty bottle or can 3. The second pressing plate door 223 prevents the empty bottle or can 3 from moving between the small bottle feeding opening 2222 and the large bottle feeding opening 2212 during the compression process, so as to ensure the compression effect of the empty bottle or can 3.

[0070] The large bottle feeding opening 2212 and the small bottle feeding opening 2222 are two relative concepts, that is, the large bottle feeding opening 2212 is larger than the small bottle feeding opening 2222. If an empty bottle or can 3 can pass through the small bottle feeding opening 2222, then the empty bottle or can 3 can also pass through the large bottle feeding opening 2212. Conversely, if the empty bottle or can 3 can pass through the large bottle feeding opening 2212, it does not necessarily mean that the empty bottle or can 3 can pass through the small bottle feeding opening 2222.

[0071] The shape of the empty bottle or can 3 is usually a cylinder. Therefore, the large bottle feeding opening 2212, the small bottle feeding opening 2222, and the throwing opening 123 are usually circular openings. Accordingly, the diameter of the large bottle feeding opening 2212 needs to be greater than the diameter of the small bottle feeding opening 2222. The size of the throwing opening 123 determines the maximum size of the empty bottle or can 3 that can be put in. In order to enable the put-in empty bottle or can 3 to reach between the compression component 21 and the pressing plate component 22, the radius of the large bottle feeding opening 2212 is equal to or slightly larger than the radius of the throwing opening 123. In this embodiment, the diameter of the small bottle feeding opening 2222 is generally 80 - 200 mm, and the diameter of the large bottle feeding opening 2212 is generally 200 - 280 mm. Limited by the distance between the throwing port support component 23 and the compression component 21, the recycling and compression mechanism 2 in this embodiment only compresses and recycles the empty bottle or can 3 with a height lower than 480 mm.

[0072] When the size of the empty bottle or can 3 is relatively large, the large bottle insertion opening 2212 serves as the moving opening for the empty bottle or can 3, and there is a relatively small gap left between the large bottle insertion opening 2212 and the outer wall of the empty bottle or can 3. When the size of the empty bottle or can 3 is relatively small, the small bottle insertion opening 2222 serves as the moving opening for the empty bottle or can 3, and at this time, there is also a relatively small gap left between the small bottle insertion opening 2222 and the outer wall of the empty bottle or can 3. Therefore, in this embodiment, when throwing the empty bottle or can 3, only a relatively small gap is left between the empty bottle or can 3 and the edge of its moving opening. Thus, the large bottle insertion opening 2212 or the small bottle insertion opening 2222 can guide the movement process of the empty bottle or can 3, inhibit the rotation of the empty bottle or can 3 between the compression assembly 21 and the pressing plate assembly 22, so that both ends of the empty bottle or can 3 can be squeezed against the compression assembly 21 and the second pressing plate door 223 as much as possible during the compression process, so that the position where the empty bottle or can 3 is squeezed is as close to the end as possible, reducing the occurrence of the squeezing point falling on the side wall of the empty bottle or can 3, and improving the compression stability of the empty bottle or can 3.

[0073] Two mutually parallel first chutes 2211 are provided on the pressing plate support 221. The edge of the first pressing plate door 222 is inserted at the two first chutes 2211. The first pressing plate door 222 is slidably arranged between the two first chutes 2211. The two first chutes 2211 guide and limit the movement of the first pressing plate door 222 on the pressing plate support 221. Two mutually parallel second chutes 2221 are provided on the first pressing plate door 222. The edge of the second pressing plate door 223 is inserted at the two second chutes 2221. The second pressing plate door 223 is slidably arranged between the two second chutes 2221. The two second chutes 2221 guide and limit the movement of the second pressing plate door 223 on the first pressing plate door 222. The second pressing plate door 223 is movably arranged on the pressing plate support 221 through the first pressing plate door 222. Through the above structure, when the pressing plate support 221 reciprocates between the compression assembly 21 and the insertion opening support assembly 23, it will drive the first pressing plate door 222 and the second pressing plate door 223 to move synchronously.

[0074] Wherein the first chute 2211 and the second chute 2221 are mutually parallel and both are perpendicular to the main body partition 161. Furthermore, during the movement of the pressing plate support 221, the first pressing plate door 222 can maintain a stable position on the first chute 2211 and the second pressing plate door 223 can maintain a stable position on the second chute 2221, thus effectively avoiding relative movement between the second pressing plate door 223 and the pressing plate support 221 during the compression process and improving the stability of the compression process.

[0075] The pressing plate support 221 will not move in the normal direction of the main body partition 161. The lifting assembly 24 is installed on the throwing port support assembly 23. Therefore, the lifting assembly 24 will not move with the pressing plate assembly 22 on the main body partition 161. When throwing an empty bottle or can 3, the lifting assembly 24 controls the throwing port support assembly 23 to open the throwing port 123. At the same time, the second pressing plate door 223 is located at the lifting assembly 24. The lifting assembly 24 will lift the second pressing plate door 223 in the normal direction of the main body partition 161 and select whether to lift the first pressing plate door 222 in the normal direction of the main body partition 161 according to the specification of the thrown empty bottle or can 3 to determine whether the empty bottle or can 3 passes through the small bottle throwing port 2222. That is, if the size of the thrown empty bottle or can 3 is large, the lifting assembly 24 will also lift the first pressing plate door 222 in the normal direction of the main body partition 161 during the throwing stage. If the size of the thrown empty bottle or can 3 is small, the lifting assembly 24 will not lift the first pressing plate door 222 during the throwing stage.

[0076] After the empty bottle or can 3 reaches between the compression assembly 21 and the pressing plate assembly 22, the lifting assembly 24 controls the throwing port support assembly 23 to close the throwing port 123. At the same time, the second pressing plate door 223 and the first pressing plate door 222 move up and down in the normal direction of the main body partition 161, and the large bottle throwing port 2212 and the small bottle throwing port 2222 are blocked again. Among them, the downward movement process of the second pressing plate door 223 and the first pressing plate door 222 is controlled by the lifting assembly 24 to avoid impact damage caused by the second pressing plate door 223 and the first pressing plate door 222 falling too fast. After the second pressing plate door 223 and the first pressing plate door 222 move downward, they move toward the compression assembly 21 on the main body partition 161 with the pressing plate support 221 to separate from the lifting assembly 24.

[0077] The pressing plate support 221 is provided with a first positioning step 2214 and a second positioning step 2215 at the bottom edge position of the large bottle throwing port 2212. After separating from the lifting assembly 24, the first pressing plate door 222 is supported on the first positioning step 2214, and the second pressing plate door 223 is supported on the second positioning step 2215. Thus, the pressing plate support 221 is used to support and lower limit the first pressing plate door 222 and the second pressing plate door 223 during the compression process of the empty bottle or can 3, avoiding direct contact between the first pressing plate door 222 and the second pressing plate door 223 and the bottom support 162, and thus avoiding wear of the first pressing plate door 222 and the second pressing plate door 223 during the movement with the pressing plate support 221.

[0078] In order for the first pressing plate door 222 and the second pressing plate door 223 to have contact points that can interact with the lifting assembly 24, so that when the pressing plate assembly 22 is at the lifting assembly 24, the lifting assembly 24 can drive the first pressing plate door 222 and the second pressing plate door 223 to perform lifting and lowering actions. A first lifting arm 2223 is provided on the first pressing plate door 222, and a second lifting arm 2232 is provided on the second pressing plate door 223, and both the second lifting arm 2232 and the first lifting arm 2223 extend towards the lifting assembly 24.

[0079] The lifting assembly 24 has two working modes to choose from:

[0080] First, when throwing a relatively large empty bottle or can 3, the lifting assembly 24 simultaneously contacts and supports the second lifting arm 2232 and the first lifting arm 2223. The lifting assembly 24 lifts the second pressing plate door 223 through the second lifting arm 2232, and the lifting assembly 24 lifts the first pressing plate door 222 through the first lifting arm 2223. When throwing a relatively small empty bottle or can 3, the lifting assembly 24 only lifts the second pressing plate door 223 through the second lifting arm 2232 and does not contact the first lifting arm 2223.

[0081] The lifting assembly 24 includes a lifting rod 246 and a lifting power mechanism connected to the lifting rod 246. The lifting rod 246 is arranged parallel to the main body partition 161, and the lifting power mechanism drives the lifting rod 246 to move up and down along the normal direction of the main body partition 161. The lifting assembly 24 drives the second pressing plate door 223 and the first pressing plate door 222 to move up and down through the lifting rod 246. The lifting rod 246 is as perpendicular as possible to the second sliding groove 2221 and the first sliding groove 2211, so that when the pressing plate assembly 22 is at the lifting assembly 24, the distance between the lifting rod 246 and the pressing plate assembly 22 can be reduced as much as possible, and the projections of the first lifting arm 2223 and the second lifting arm 2232 in the normal direction of the main body partition 161 can fall on the lifting rod 246 as much as possible, thereby increasing the contact area when the lifting rod 246 contacts the first lifting arm 2223 and the second lifting arm 2232, and increasing the control stability of the lifting rod 246 over the first lifting arm 2223 and the second lifting arm 2232.

[0082] In the relative direction of the compression assembly 21 and the spout support assembly 23, the length of the second lifting arm 2232 is greater than that of the first lifting arm 2223. Therefore, the second lifting arm 2232 is closer to the spout support assembly 23 than the first lifting arm 2223. The lifting rod 246 moves down to the lowest position. At this time, the pressing plate assembly 22 moves towards the spout support assembly 23. When throwing a smaller empty bottle or can 3, only when the second lifting arm 2232 projects downward onto the lifting rod 246 in the normal direction of the main body partition 161, the lifting rod 246 rises and only lifts the second lifting arm 2232. At this time, the second pressing plate door 223 slides upward at the second sliding groove 2221 to open the small bottle delivery port 2222, and the first pressing plate door 222 still supports on the first positioning step 2214. When throwing a larger empty bottle or can 3, when both the first lifting arm 2223 and the second lifting arm 2232 project downward onto the lifting rod 246 in the normal direction of the main body partition 161, the lifting rod 246 can lift both the first lifting arm 2223 and the second lifting arm 2232 at this time, so as to open the entire large bottle delivery port 2212. When throwing a larger empty bottle or can 3, the lifting order of the lifting rod 246 for the first lifting arm 2223 and the second lifting arm 2232 is not limited. For example, in this embodiment, when the pressing plate assembly 22 just reaches the lifting rod 246, the first lifting arm 2223 is closer to the lifting rod 246 in the normal direction of the main body partition 161 than the second lifting arm 2232. Therefore, the lifting rod 246 will first lift the first lifting arm 2223, and then lift the second lifting arm 2232. In other embodiments, by changing the height difference between the first lifting arm 2223 and the second lifting arm 2232 in the normal direction of the main body partition 161, the lifting rod 246 can also first lift the second lifting arm 2232, or lift the first lifting arm 2223 and the second lifting arm 2232 simultaneously.

[0083] Second, as adopted in this embodiment, a positioning surface 2233 is additionally provided on the second pressing plate door 223, and a stop surface 2224 is provided on the first pressing plate door 222. When the second pressing plate door 223 covers the small bottle delivery port 2222, the positioning surface 2233 can support on the stop surface 2224, so that the first pressing plate door 222 supports and limits the second pressing plate door 223. At this time, when throwing a larger empty bottle or can 3, the lifting rod 246 only contacts and supports the first lifting arm 2223. By virtue of the supporting effect of the first pressing plate door 222 on the second pressing plate door 223, the lifting rod 246 can simultaneously lift the first pressing plate door 222 and the second pressing plate door 223 through the first lifting arm 2223, and the lifting rod 246 does not contact the second lifting arm 2232. When throwing a smaller empty bottle or can 3, the lifting assembly 24 only lifts the second pressing plate door 223 through the second lifting arm 2232 without contacting the first lifting arm 2223.

[0084] The feeding port support assembly 23 includes a feeding port support 231 and a protective door 234. The feeding port support 231 is fixed on the bottom support 162. A large bottle feeding through port 2342 is provided on the feeding port support 231 and is arranged opposite to the large bottle feeding port 2212. The protective door 234 moves at the large bottle feeding through port 2342 to control the opening and closing of the large bottle feeding through port 2342. The large bottle feeding through port 2342 is also opposite to the throwing port 123. When the protective door 234 closes the large bottle feeding through port 2342, since the large bottle feeding through port 2342 and the throwing port 123 are very close, the protective door 234 also closes the throwing port 123 together. At this time, the empty bottle cans 3 cannot enter the recycling and compression mechanism 2. When the protective door 234 leaves from the large bottle feeding through port 2342, the large bottle feeding through port 2342 and the throwing port 123 are opened simultaneously. At this time, as long as the second pressing plate door 223 is lifted, or the second pressing plate door 223 and the first pressing plate door 222 are lifted, the empty bottle cans 3 can be thrown into the recycling and compression mechanism 2.

[0085] A protective door connecting arm 2341 extends from the top of the protective door 234 towards the lifting rod 246. The protective door connecting arm 2341 is suspended on the lifting rod 246 and fixed to the lifting rod 246, so that the protective door 234 is fixed to the lifting rod 246, and the protective door 234 can move synchronously with the lifting rod 246. The controller 14 is electrically connected to the lifting power mechanism. The controller 14 controls the movement of the lifting rod 246 through the lifting power mechanism, and the lifting rod 246 then drives the protective door 234 to move at the large bottle feeding through port 2342, thereby effectively avoiding the situation that users put empty bottle cans into the throwing port 123 without barcode scanning.

[0086] When the lifting rod 246 moves upward in the normal direction of the main body partition 161, it drives the protective door 234 to open the large bottle feeding through port 2342. At the same time, the pressing plate assembly 22 is already at the position of the lifting rod 246. During the opening process of the large bottle feeding through port 2342, the lifting rod 246 can also lift the second lifting arm 2232, or lift the second lifting arm 2232 and the first lifting arm 2223, so that after the empty bottle cans 3 enter the throwing port 123, they can directly reach between the compression assembly 21 and the pressing plate assembly 22. The lifting rod 246 controls the pressing plate assembly 22 and the feeding port support assembly 23 at the same time, simplifies the control steps, and at the same time avoids the situation that the pressing plate assembly 22 is not fully opened after the large bottle feeding through port 2342 is opened, which hinders the movement of the empty bottle cans 3 towards the compression assembly 21.

[0087] Preferably, a protective door sliding groove 232 perpendicular to the main body partition 161 is provided at the edge position of the large bottle feeding through port 2342 on the feeding port support 231. The edge of the protective door 234 is slidably connected to the protective door sliding groove 232 to guide the movement of the protective door 234 through the protective door sliding groove 232. The lifting slider 2412

[0088] In this embodiment, the lifting power mechanism includes a U-shaped lifting bracket, a lifting gear 245, a lifting rack 243, and a lifting motor 244. The lower cross beam 242 of the lifting bracket is fixed to the top of the feeding port bracket 231, and the entire lifting bracket is supported by the feeding port bracket 231. The upper cross beam 247 and the lower cross beam 242 of the lifting bracket cooperate to keep the two longitudinal beams 241 parallel. There are two lifting racks 243, and the two lifting racks 243 are respectively fixed on the two longitudinal beams 241 of the lifting bracket so that the lifting racks 243 are fixed relative to the compression assembly 21, and the two lifting racks 243 are perpendicular to the main body partition 161. Lifting grooves 2411 extending in the normal direction of the main body partition 161 are formed on the longitudinal beams 241. The lifting rod 246 passes through the two lifting grooves 2411 at the same time. The lifting grooves 2411 guide the lifting and lowering movement of the lifting rod 246 in the normal direction of the main body partition 161 and provide the lifting and lowering space for the lifting rod 246. The end of the lifting rod 246 moves in the lifting groove 2411 so that the lower cross beam 242 avoids the lifting process of the lifting rod 246 laterally. The lifting grooves 2411 limit the lifting rod 246 on the lifting bracket, so the lifting rod 246 accurately moves to the top of the large bottle feeding opening 2342 to lift the second lifting arm 2232 and the first lifting arm 2223. A lifting slider 2412 is installed at each end of the lifting rod 246. The end of the lifting rod 246 slides in the lifting groove 2411 through the lifting slider 2412. At the same time, the lifting slider 2412 cooperates with the inner wall of the lifting groove 2411 so that the lifting rod 246 does not rotate on the lifting bracket, thus avoiding relative sliding between the lifting rod 246 and the second lifting arm 2232 and the first lifting arm 2223 during the lifting and lowering movement of the lifting rod 246. There are two lifting gears 245. The two lifting gears 245 are respectively rotatably installed at both ends of the lifting rod 246 through two lifting sliders 2412, and the two lifting gears 245 are respectively engaged with the two lifting racks 243. The number of lifting motors 244 is also two. The output shafts of the two lifting motors 244 are respectively fixed on the two lifting gears 245. The two lifting motors 244 drive the two lifting gears 245 to lift and lower synchronously on the two lifting racks 243, thereby driving the lifting rod 246 to lift and lower smoothly. At the same time, after the lifting motor 244 stops working, the self-locking force between the lifting gear 245 and the lifting rack 243 is used to lock the lifting rod 246 at the middle position of the lifting groove 2411, so that the large bottle feeding opening 2342 is opened for enough time for the user to throw the empty bottle can 3. The corresponding lifting motor 244 is electrically connected to the controller 14.

[0089] In addition, a platen support in-place switch 2421 is installed on the lower cross beam 242 in this embodiment. The platen support in-place switch 2421 is electrically connected to the controller 14. The platen support in-place switch 2421 detects the movement of the platen support 221. When the platen support 221 reaches the lifting rod 246, the platen support in-place switch 2421 is triggered. The platen support in-place switch 2421 sends a signal to the controller 14, and then the controller 14 controls the lifting rod 246 to start the lifting action through the lifting motor 244.

[0090] A first platen door reset detection switch 2422 is installed on the lower cross beam 242. When the lifting rod 246 drives the first platen door 222 to descend, when the first platen door 222 contacts the first positioning step 2214, the first platen door 222 can trigger the first platen door reset detection switch 2422.

[0091] A second platen door reset detection switch 2424 is installed on the lower cross beam 242. When the lifting rod 246 drives the second platen door 223 to descend, when the second platen door 223 contacts the second positioning step 2215, the second platen door 223 can trigger the second platen door reset detection switch 2424.

[0092] Both the first platen door reset detection switch 2422 and the second platen door reset detection switch 2424 are electrically connected to the controller 14. If a relatively large empty bottle or can 3 is thrown, the platen assembly 22 can start to move and squeeze the empty bottle or can 3 only when both the second platen door reset detection switch 2424 and the first platen door reset detection switch 2422 are triggered. If a relatively small empty bottle or can 3 is thrown, the platen assembly 22 can start to move and squeeze the empty bottle or can 3 only when the second platen door reset detection switch 2424 is triggered.

[0093] In addition, a lifting rod reset switch 2423 is also installed on the lower cross beam 242 in this embodiment, and a lifting rod stop switch 2471 is installed on the upper cross beam 247. Both the lifting rod reset switch 2423 and the lifting rod stop switch 2471 are electrically connected to the controller 14. When the lifting rod 246 moves to the lifting rod reset switch 2423 or the lifting rod stop switch 2471, the lifting rod reset switch 2423 or the lifting rod stop switch 2471 is triggered. The lifting rod reset switch 2423 or the lifting rod stop switch 2471 sends a signal to the controller 14 to control the lifting motor 244 to stop rotating.

[0094] The compression assembly 21 includes a compression bracket 211, which is mounted on the main body partition 161 and cannot move on the main body partition 161. When the empty bottle jar 3 is squeezed, the two ends of the empty bottle jar 3 are aligned with the compression bracket 211 and the second pressure plate door 223 respectively. In this embodiment, the second pressure plate door 223 and the compression bracket 211 are provided with air holes 2231. Since the bottle cap has been removed or opened from the end opening of the empty bottle jar 3, the air holes 2231 are connected with the vial delivery port 2222 during the compression process, and the residual liquid in the empty bottle jar 3 can be sprayed out through the air holes 2231. During the compression process, the empty bottle jar 3 can also maintain communication with the atmosphere through the air holes 2231, so as to prevent the empty bottle jar 3 from being held in air during the compression process, resulting in excessive squeezing force between the compression bracket 211 and the second pressure plate door 223, which triggers the controller 14 to alarm or even damage the recovery compression mechanism 2.

[0095] The slot bracket assembly 23 also includes a guide support column 235 for guiding and supporting the empty bottle can 3 during the compression process, and the two ends of the guide support column 235 are respectively fixed to the lower edge of the large bottle delivery port 2342 and the compression bracket 211. There are multiple guide support columns 235 and they are arranged in sequence along the circumference of the large bottle delivery port 2342. The empty bottle can 3 can be supported and guided by the guide support column 235 during the compression process to avoid the empty bottle can 3 from rotating and running off during the compression process as much as possible, so that the empty bottle can 3 can be compressed as a whole as much as possible, reducing the occurrence of the empty bottle can 3 being partially uncompressed, and preventing the empty bottle can 3 from falling from between the compression bracket 211 and the second pressure plate door 223 during the compression process to cause an alarm.

[0096] Correspondingly, a guide column groove 2213 is provided at the bottom edge of the pressure plate bracket 221 at the large bottle delivery port 2212, and the guide support column 235 passes through the guide column groove 2213, so that the pressure plate bracket 221 can avoid the guide support column 235 during the movement on the main partition 161. At the same time, the guide support column 235 can also guide the reciprocating movement of the pressure plate bracket 221 between the delivery port bracket 231 and the compression bracket 211.

[0097] The guide support column 235 is relatively slender, and the connection strength between the compression bracket 211 and the slot bracket 231 is limited. Therefore, in this embodiment, four connecting rods 27 thicker than the guide support column 235 are arranged between the compression bracket 211 and the slot bracket 231. The two ends of the connecting rod 27 are respectively fixed to the compression bracket 211 and the slot bracket 231, thereby improving the connection strength between the compression bracket 211 and the slot bracket 231. Four positioning grooves 2111 are arranged on the compression bracket 211 to position the ends of the four connecting rods 27 respectively, and are fixed by studs.

[0098] In this embodiment, the compression assembly 21 further includes a compression motor 212 disposed on the compression bracket 211, a driving sprocket 214 driven by the compression motor 212, a driven sprocket 215, a chain 216, and a lead screw 218. The driving sprocket 214 and the driven sprocket 215 are driven by the chain 216 to drive the driven sprocket 215 to rotate. Both ends of the lead screw 218 are positioned on the compression bracket 211 and the feeding port bracket 231 through bearings respectively. The driven sprocket 215 is mounted on the end of the lead screw 218 located on the compression bracket 211, and the driven sprocket 215 drives the lead screw 218 to rotate. A tapping screw 225 is mounted on the pressure plate bracket 221. The lead screw 218 passes through the tapping screw 225 and is threadedly connected to the tapping screw 225. A plurality of guiding and supporting columns 235 cooperate to circumferentially position the pressure plate bracket 221, and the guiding and supporting columns 235 are parallel to the lead screw 218. Therefore, during the rotation of the lead screw 218, the pressure plate bracket 221 will be driven to reciprocate axially along the lead screw 218.

[0099] In this embodiment, the number of both the driven sprocket 215 and the lead screw 218 is two to improve the running stability of the compression bracket 211. Therefore, the compression assembly 21 in this embodiment further includes an adjusting plate 213 mounted on the compression bracket 211. The position of the driving sprocket 214 is finely adjusted by using the adjusting plate 213 to adjust the tension of the chain 216, so that the transmission force is reasonably distributed to improve the synchronous rotation of the lead screw 218.

[0100] The compression motor 212 is also electrically connected to the controller 14 to control the moving stroke distance of the pressure plate bracket 221 in cooperation with the scanning result, and to adjust the relative positions of the first lifting arm 2223 and the second lifting arm 2232 with respect to the lifting rod 246 to determine the lifting object of the lifting rod 246.

[0101] An avoidance opening 2216 is formed by inward concavity at the edge of the pressure plate bracket 221. The connecting rod 27 passes through the avoidance opening 2216 to avoid the connecting rod 27 during the reciprocating movement of the pressure plate bracket 221. In addition, a pressure plate bracket limit switch 271 electrically connected to the controller 14 is provided at a position on the connecting rod 27 close to the compression bracket 211. When the pressure plate bracket 221 moves to the position of the pressure plate bracket limit switch 271, the side wall of the avoidance opening 2216 triggers the pressure plate bracket limit switch 271, and the compression motor 212 stops working to prevent the pressure plate bracket 221 from approaching the compression bracket 211 further, resulting in excessive pressure between the second pressure plate door 223 and the compression bracket 211 and causing damage.

[0102] In order to reduce the increase in occupied space caused by the re-expansion of the empty bottles and cans 3 after compression, the recycling and compression mechanism 2 further includes a heating component 26 installed on the compression component 21. More specifically, the heating component 26 is installed on the compression bracket 211. The heating component 26 heats the empty bottles and cans 3 during the compression process of the empty bottles and cans 3, thereby further stabilizing the compression effect. The dropping port 163 is located below the compression bracket 211. After the compression of the empty bottles and cans 3 is completed, the pressing plate assembly 22 moves towards the feeding port bracket assembly 23, and the pressing plate assembly 22 no longer presses and positions the end of the compressed empty bottles and cans 3. Therefore, the compressed empty bottles and cans 3 stay on the compression bracket 211 briefly. The occupied space of the compressed empty bottles and cans 3 is very small. Therefore, the compressed empty bottles and cans 3 on the compression bracket 211 can fall through the gap between the adjacent guiding support columns 235 under the action of gravity to the dropping port 163 to enter the empty bottles and cans collection bag 181 for recycling.

[0103] Specifically, the heating component 26 includes a heating bracket 261, a fan 262, a fin heating tube 263, and a bottle body detection plate 264. During the compression process of the empty bottles and cans 3, a heating space is formed by enclosing between the compression bracket 211 and the pressing plate bracket 221. The empty bottles and cans 3 are located in the heating space during compression. The heating bracket 261 is installed on the side of the compression bracket 211. The fin heating tube 263 is located inside the heating bracket 261. The fan 262 is installed on the side wall of the heating bracket 261. The bottle body detection plate 264, the fin heating tube 263, and the fan 262 are all electrically connected to the controller 14. The bottle body detection plate 264 is installed on the heating bracket 261. The bottle body detection plate 264 is located on the side of the heating bracket 261 close to the pressing plate assembly 22. After the bottle body detection plate 264 detects the empty bottles and cans 3, it sends a signal to the controller 14. On the one hand, the controller 14 controls the compression motor 212 to work, so that the pressing plate assembly 22 starts to compress the empty bottles and cans 3. On the other hand, the controller 14 controls the fin heating tube 263 and the fan 262 to work. The fin heating tube 263 heats the air, and the fan 262 guides the heated air into the heating space to heat and shape the empty bottles and cans 3.

[0104] In order to reduce the heat dissipation in the heating space during the heating process, the recycling and compression mechanism 2 further includes a heat preservation component 25.

[0105] Specifically, the heat preservation component 25 includes a heat preservation slide plate 256, a heat preservation bracket 251, and a heat preservation power mechanism. The heat preservation bracket 251 is fixed at the bottom of the compression bracket 211. The heat preservation power mechanism drives the heat preservation slide plate 256 to move on the heat preservation bracket 251. A space for the heat preservation slide plate 256 to move is left at the bottom of the compression bracket 211 for the heat preservation slide plate 256 to enter and exit the heating space.

[0106] During the heating process, the heat preservation slide plate 256 moves to the bottom of the heating space. On the one hand, it can reduce the heat loss from the bottom of the heating space inside the heating space, ensuring the thermoforming effect of the empty bottle or can 3. On the other hand, it can block the dropping port 163 to prevent the empty bottle or can 3 from dropping from the dropping port 163 during the heating and compression process. After the empty bottle or can 3 is heated, the heat preservation power mechanism controls the heat preservation slide plate 256 to withdraw from the heating space, exposing the dropping port 163 again, enabling the empty bottle or can 3 to smoothly drop to the dropping port 163.

[0107] The heat preservation power mechanism includes a transmission rod 257, a transmission motor 254, a transmission gear 255 and a transmission rack 253. An extension of the edge of the heat preservation slide plate 256 forms a transmission rod connecting arm 2561. The transmission rod connecting arm 2561 is clamped on the transmission rod 257 to connect the heat preservation slide plate 256 with the transmission rod 257, and the transmission rod 257 drives the heat preservation slide plate 256 to move on the main body partition 161. The transmission rack 253 is fixed on the heat preservation bracket 251. The transmission gear 255 is installed at the end of the transmission rod 257, and the transmission gear 255 meshes with the transmission rack 253. The transmission gear 255 is fixed to the motor shaft of the transmission motor 254. The transmission motor 254 drives the transmission gear 255 to roll on the transmission rack 253, and then the transmission gear 255 drives the transmission rod 257 to move. The transmission rack 253 is parallel to the relative direction of the compression bracket 211 and the pressure plate bracket 221, so the heat preservation slide plate 256 can move towards or away from the compression bracket 211.

[0108] To prevent the transmission rod 257 from detaching from the heat preservation bracket 251, a guiding chute 2511 parallel to the transmission rack 253 is provided on the heat preservation bracket 251. A guiding slider 2512 is fixed at the end of the transmission rod 257. The guiding slider 2512 is slidably arranged in the guiding chute 2511. The inner wall of the guiding chute 2511 cooperates with the guiding slider 2512. On the one hand, it guides the moving direction of the transmission rod 257 on the heat preservation bracket 251 to prevent the transmission rod 257 from detaching from the heat preservation bracket 251. On the other hand, it circumferentially positions the transmission rod 257 to prevent the transmission rod 257 from driving the heat preservation slide plate 256 to rotate on the heat preservation bracket 251, resulting in the situation where the heat preservation slide plate 256 cannot enter or leave the heating space. The transmission gear 255 is rotatably installed on the guiding slider 2512 to be connected with the transmission rod 257 through the guiding slider 2512.

[0109] In order to make the thermal insulation slide plate 256 move more smoothly, the number of transmission gears 255 and transmission racks 253 is two. The two transmission racks 253 are respectively fixed on the two side walls of the thermal insulation bracket 251, and the two transmission gears 255 are respectively meshed with the two transmission racks 253. Both ends of the corresponding transmission rod 257 are fixed with guide sliders 2512, and there are also two guide chutes 2511. The two guide sliders 2512 are respectively slidably connected in the two guide chutes 2511. The two transmission racks 253 are parallel to each other, and the two guide chutes 2511 are parallel to each other.

[0110] In order to save costs, the number of drive motors 254 in this embodiment is only one. The drive motor 254 is only fixed to one of the drive gears 255. When the drive rod 257 moves, it drives the other drive gear 255 to roll on the drive rack 253 with which it is meshed. For the sake of easy distinction, the drive gear 255 directly connected to the drive motor 254 in this embodiment is called the driving gear, and the drive gear 255 driven by the drive rod 257 is called the driven gear. A gear pressing plate 258 is arranged on the outer side of the driven gear. The gear pressing plate 258 is fixed on the guide slider 2512 on which the driven gear is installed. The gear pressing plate 258 restricts the driven gear between the guide slider 2512 and the gear pressing plate 258 to prevent the driven gear from disengaging from the drive rod 257.

[0111] The thermal insulation bracket 251 includes two parallel limit rods 252. The limit rods 252 are perpendicular to the guide chutes 2511. Both ends of one of the limit rods 252 are respectively located at the front ends of the two guide chutes 2511, and both ends of the other limit rod 252 are respectively located at the rear ends of the two guide chutes 2511. Therefore, the whole thermal insulation bracket 251 is in a rectangular shape with an opening in the middle.

[0112] A first limit switch 2521 is installed on one of the limit rods 252, and a second limit switch 2522 is installed on the other limit rod 252. The drive motor 254, the first limit switch 2521, and the second limit switch 2522 are all electrically connected to the controller 14. An after-trigger arm 2562 is formed by extending the edge of the heat preservation slide plate 256. When the drive rod 257 moves towards the heating space, the trigger arm 2562 gradually approaches the second limit switch 2522. When the trigger arm 2562 triggers the second limit switch 2522, the second limit switch 2522 sends a signal to the controller 14, and the controller 14 controls the drive motor 254 to stop working and simultaneously controls the heating component 26 to start working officially. After the heating component 26 finishes working, the controller 14 controls the drive motor 254 to work, causing the drive rod 257 to gradually move away from the heating space and driving the trigger arm 2562 to move towards the first limit switch 2521. When the trigger arm 2562 triggers the first limit switch 2521, the first limit switch 2521 sends a signal to the controller 14, and the drive motor 254 stops working. At this time, the heat preservation slide plate 256 completes the reset action. The first limit switch 2521 and the second limit switch 2522 cooperate to limit the forward and backward travel of the drive rod 257, preventing the guide slider 2512 from hitting the end wall of the guide chute 2511.

[0113] In this embodiment, the compression assembly 21 further includes a compression stroke compensation assembly 217. The compression stroke compensation assembly 217 includes a first sealing plate 2171, a second sealing plate 2173, a compensation spring 2172, and a compensation pressing plate 2174.

[0114] The compensation pressing plate 2174 is movably arranged between the compression bracket 211 and the pressing plate bracket 221. The compensation pressing plate 2174 replaces the compression bracket 211 to contact the end of the empty bottle or can 3 to compress the empty bottle or can 3.

[0115] A hot air cavity is formed between the compensation pressing plate 2174 and the compression bracket 211. The fan 262 guides hot air into the hot air cavity to make the hot air relatively concentrated and converge. The compensation pressing plate 2174 is provided with hot air holes 21741. The hot air in the hot air cavity can be sent to the position where the empty bottle or can 3 is compressed through the hot air holes 21741, so as to directly blow the empty bottle or can 3, increasing the utilization efficiency of hot air. At the same time, the hot air holes 21741 are communicated with the air permeable holes 2231 on the compression bracket 211 through the hot air cavity, preventing the empty bottle or can 3 from being airtight during the compression process.

[0116] During the process of squeezing one end of the empty bottle or can 3 by the second pressing plate door 223, the other end of the empty bottle or can 3 can push the compensation pressing plate 2174 towards the compression bracket 211, so as to compensate for the compression stroke of the empty bottle or can 3, adjust the compression degree of the empty bottle or can 3, and the compensation spring 2172 will be compressed and deformed when the empty bottle or can 3 pushes the compensation pressing plate 2174. After the compression molding of the empty bottle or can 3 is completed and separated from the compensation pressing plate 2174, the compensation pressing plate 2174 can be reset under the reset action of the compensation spring 2172.

[0117] The bottom of the hot air cavity is open. During the heating process, the heat preservation slide plate 256 moves to the bottom of the hot air cavity to block the bottom of the hot air cavity, thereby reducing the heat loss at the bottom of the hot air cavity.

[0118] The first sealing plate 2171 is fixed on the side wall of the compression bracket 211 facing the compensation pressing plate 2174, and the second sealing plate 2173 is fixed on the side wall of the compensation pressing plate 2174 facing the compression bracket 211. Both the first sealing plate 2171 and the second sealing plate 2173 are located at the top of the hot air cavity. During the process of the compensation pressing plate 2174 moving towards the compression bracket 211, the first sealing plate 2171 and the second sealing plate 2173 are gradually stacked, thereby increasing the sealing performance at the top of the hot air cavity, reducing the heat loss at the top of the hot air cavity, increasing the thermoforming efficiency, and shortening the working time required by the heating component.

[0119] In this embodiment, the second sealing plate 2173 is located above the first sealing plate 2171. The first sealing plate 2171 is provided with a guide rod 21711, and the second sealing plate 2173 is provided with a guide groove 21731. The guide rod 21711 is located at the guide groove 21731 to limit the relative movement direction between the compensation pressing plate 2174 and the compression bracket 211. At the same time, the end walls at both ends of the guide groove 21731 limit the movement range of the guide rod 21711, thereby limiting the movement stroke of the compensation pressing plate 2174 on the compression bracket 211.

[0120] The second sealing plate 2173 is provided with a lug 21732, and both ends of the compensation spring 2172 are fixed on the lug 21732 and the compression bracket 211 respectively, so as to squeeze the compensation spring 2172 during the process of the compensation pressing plate 2174 moving towards the compression bracket 211.

[0121] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
