[0023] In some embodiments, at least two sets of the support member, the first molding member, and the second molding member are provided, and at least two sets of the support member, the first molding member, and the second molding member are arranged side by side along a third direction, wherein the third direction, the second direction, and the first direction intersect each other.

[0024] According to the forming equipment provided in this application, the forming equipment is used to automatically form paper card trays, thereby reducing manpower in the paper card tray preparation process and improving the forming efficiency of paper card trays. The paper card tray includes a first sub-part and a folding part that are folded together. In the initial state, the first sub-part and the folding part are connected to each other and are on the same plane. After the paper card tray is formed, the first sub-part and the folding part are folded together, forming a preset angle between them. The forming equipment includes a support member, a first forming member, and a second forming member. Through the cooperation between the support member, the first forming member, and the second forming member, the first sub-part and the folding part are folded together to form the preset angle, completing the preparation of the paper card tray. The support member is used to support and bear the paper card tray. The support member includes a first support part and a second support part connected in a first direction. The first support part has a first support surface in a second direction, and the second support part has a first top surface in a second direction. The second support part protrudes from the first support part in the second direction and includes a second support surface connected between the first top surface and the first support surface. When the card tray is supported by the support member, the first support part is supported on the first sub-part, and the first sub-part is in partial contact with the structure of the first support surface. The second support part is supported on the folded part, and the folded part is in contact with the structure of the first top surface and the structure of the second support surface. At the connection position between the first support surface and the second support surface, corresponding to the connection position between the first sub-part and the folded part in the card tray, there is a gap between the card tray and the support member. The first forming member overlaps with the first support surface in the second direction and slides relative to the support member in the second direction. After the card tray is supported by the support member, the first forming member slides towards the side closer to the first support surface in the second direction and contacts the first sub-part in the card tray. Under the action of the first forming member, the first sub-part is fitted to the first support surface. Under the self-inertia between the first sub-part and the folded part in the card tray, the folded part is also fitted to the second support surface, and an initial angle is formed between the first sub-part and the folded part. The second forming member is located on the side of the first top surface away from the first support surface in the second direction, and on the side of the second support portion away from the first support portion in the first direction. The second forming member is slidably disposed relative to the support member in the first direction. When the second forming member slides relative to the support member in the first direction, the second forming member can contact the end of the folded portion away from the first sub-part, and drive the end of the folded portion away from the first sub-part to fold further, thereby further consolidating and reducing the folding angle between the folded portion and the first sub-part, so as to ensure that after the surrounding restrictive structure is removed, the first sub-part and the folded portion can still have a preset folding angle after a certain degree of elastic recovery, thus realizing the forming of the paper card tray.

[0045] In modern logistics and transportation, products are packaged before shipment to protect them and reduce the probability of damage during transit. Currently, cardboard boxes are commonly used for packaging, with paper trays placed inside to cushion the product from compression and vibration during transport, thus providing protection.

[0046] To ensure the protective effect of paper card trays on products, paper card trays usually need to be folded to form a specific shape. The production process of paper card trays requires a lot of manpower and has low production efficiency.

[0047] In view of this, firstly, please refer to Figures 1 to 4This application provides a forming device 100 for forming a paper card tray 200, which includes a first sub-part 201 and a folded part 202 connected to each other. The forming device 100 includes a support member 10, a first forming member 20, and a second forming member 30. The support member 10 includes a first support part 11 and a second support part 12 connected in a first direction X. The first support part 11 has a first support surface M1 in a second direction Y, and the second support part 12 has a first top surface M2 in the second direction Y. The second support part 12 protrudes from the first support part 11 in the second direction Y and includes a second support surface M3 connecting the first top surface M2 and the first support surface M1. The first direction X and the second direction Y intersect. The first forming member 20 overlaps with the first support surface M1 in the second direction Y, and the first forming member 20 is slidably disposed relative to the support member 10 along the second direction Y. The second molded part 30 is located on the side of the first top surface M2 away from the first support surface M1 in the second direction Y, and on the side of the second support part 12 away from the first support part 11 in the first direction X. The second molded part 30 is slidably disposed relative to the support part 10 along the first direction X. The first support surface M1 is used to support the first sub-part 201, and the second support surface M3 is used to support the folded part 202. The second support surface M3 includes a first end connected to the first support surface M1 and a second end connected to the first top surface M2. The distance between the first end and the second end is less than the dimension of the folded part 202 in the direction from the first sub-part 201 to the folded part 202.

[0048] The forming equipment 100 provided in this application embodiment is used to automatically form a paper card tray 200, thereby reducing manpower in the paper card tray 200 preparation process and improving the forming efficiency of the paper card tray 200. The paper card tray 200 includes a first sub-part 201 and a folding part 202 that are folded together. In the initial state, the first sub-part 201 and the folding part 202 are connected to each other and are on the same plane, with an angle of 180 degrees between them. After the paper card tray 200 is formed, the first sub-part 201 and the folding part 202 are folded together, but they remain connected to each other, forming a preset angle between them. This preset angle is less than 180 degrees. For example, the preset angle can be 60 degrees, 90 degrees, or 120 degrees.

[0049] Specifically, the forming equipment 100 includes a support member 10, a first forming member 20, and a second forming member 30. The support member 10 is used to support and carry the paper card tray 200. The first forming member 20 is used to assist in the initial forming of the paper card tray 200. The second forming member 30 is used to assist in the further forming of the paper card tray 200. Through the cooperation between the support member 10, the first forming member 20, and the second forming member 30, the first sub-part 201 and the folding part 202 in the paper card tray 200 are folded together, so that the first sub-part 201 and the folding part 202 form a preset angle, thereby completing the preparation of the paper card tray 200. Optionally, during the interaction between the support member 10, the first molding member 20, and the second molding member 30, they can be simultaneously connected and disposed on the same frame 70 to determine their initial relative positions. Alternatively, they can be configured as separate units, as long as they can cooperate with each other. Preferably, the support member 10, the first molding member 20, and the second molding member 30 are simultaneously connected and disposed on the same frame 70.

[0050] The support member 10 is used to support and bear the paper card tray 200. The support member 10 includes a first support portion 11 and a second support portion 12 connected in a first direction X. The first support portion 11 has a first support surface M1 in a second direction Y, and the second support portion 12 has a first top surface M2 in the second direction Y. The second support portion 12 protrudes from the first support portion 11 in the second direction Y and includes a second support surface M3 connecting the first top surface M2 and the first support surface M1. The first direction X and the second direction Y intersect. The first direction X can be a horizontal direction, and the second direction Y can be a vertical direction. When the paper card tray 200 is on the support member 10, the paper card tray 200 is supported and beared vertically by the support member 10. Based on the gravity of the paper card tray 200, the paper card tray 200 can naturally contact and support the support member 10, improving the stability of the paper card tray 200 on the support member 10.

[0051] The second support portion 12 protrudes from the first support portion 11 in the second direction Y. That is, the height of the first top surface M2 in the vertical direction is higher than the height of the first support surface M1 in the vertical direction, and there is a certain height difference between the first top surface M2 and the first support surface M1 in the vertical direction. The second support surface M3 connects the first top surface M2 and the first support surface M1. When the paper tray 200 is supported by the support member 10, the first sub-part 201 and the folding part 202 in the paper tray 200 are arranged in the first direction X. The first support portion 11 is supported on the first sub-part 201, and the first sub-part 201 is in partial structural contact with the first support surface M1. The second support portion 12 is supported on the folding part 202, and the folding part 202 is in partial structural contact with the first top surface M2 and the second support surface M3. Because there is a certain height difference between the first top surface M2 and the first support surface M1, the first sub-part 201 and the folding part 202 of the paper card tray 200 are at 180 degrees in the initial state. At the connection position between the first support surface M1 and the second support surface M3, corresponding to the connection position between the first sub-part 201 and the folding part 202 in the paper card tray 200, there is a gap between the paper card tray 200 and the support member 10.

[0052] The first forming member 20 is used to assist in the initial forming of the paper card tray 200. The first forming member 20 overlaps with the first support surface M1 in the second direction Y, and slides relative to the support member 10 in the second direction Y. When the paper card tray 200 is supported by the support member 10, the first forming member 20 slides in the second direction Y toward the side closer to the first support surface M1 and contacts the first sub-part 201 in the paper card tray 200. Under the action of the first forming member 20, the first sub-part 201 is pressed against the first support surface M1. At the connection position between the first support surface M1 and the second support surface M3, corresponding to the connection position between the first sub-part 201 and the folding part 202 in the paper card tray 200, the gap between the paper card tray 200 and the support member 10 disappears, and the first sub-part 201 is fitted to the first support surface M1. Under the self-inertia between the first sub-part 201 and the folding part 202 in the paper card tray 200, the folding part 202 is also fitted to the second support surface M3. With the assistance of the first molded part 20, the first sub-part 201 is supported and attached to the first support surface M1, and the folded part 202 is supported and attached to the second support surface M3. Since the second support part 12 protrudes from the first support part 11 in the second direction Y, and there is an angle between the second support surface M3 and the first support surface M1, when the first sub-part 201 is attached to the first support surface M1 and the folded part 202 is attached to the second support surface M3, an initial angle is also formed between the first sub-part 201 and the folded part 202. The sliding of the first molded part 20 can be driven by a first driving member, which can be a cylinder.

[0053] Considering that the first sub-part 201 and the folded part 202 in the paper card tray 200 form an included angle, after the surrounding restrictive structure is removed, the first sub-part 201 and the folded part 202 will undergo a certain degree of elastic recovery. In order to ensure that the first sub-part 201 and the folded part 202 still have a stable included angle after a certain degree of elastic recovery, in this embodiment of the application, the forming device 100 further includes a second forming member 30, which is used to assist in the further forming of the paper card tray 200. The second forming member 30 is located on the side of the first top surface M2 away from the first support surface M1 in the second direction Y, and on the side of the second support part 12 away from the first support part 11 in the first direction X. The second forming member 30 is slidably disposed relative to the support member 10 along the first direction X. At the same time, the second support surface M3 includes a first end connected to the first support surface M1 and a second end connected to the first top surface M2. The distance between the first end and the second end is less than the dimension of the folded part 202 in the direction of the straight folded part 202 formed by the first sub-part 201. In other words, after the folded portion 202 is attached to the second support surface M3, the end of the folded portion 202 away from the first sub-part 201 extends beyond the second support portion 12. When the second forming member 30 slides relative to the support member 10 along the first direction X, the second forming member 30 can contact the end of the folded portion 202 away from the first sub-part 201 and drive the end of the folded portion 202 away from the first sub-part 201 to fold further. Based on the first forming member 20 pressing the first sub-part 201 against the first support surface M1, the position of the first sub-part 201 can be fixed. During the sliding process, the second forming member 30 can further consolidate and reduce the folding angle between the folded portion 202 and the first sub-part 201, so as to ensure that after the surrounding restrictive structure is removed, the first sub-part 201 and the folded portion 202 can still have a preset folding angle after a certain degree of elastic recovery, thereby realizing the forming of the paper card tray 200. For the sliding of the second molded part 30, a second driving component can be set to drive it, and the second driving component can be set as a cylinder.

[0054] In summary, in this embodiment, the forming equipment 100 is used to automatically form the paper card tray 200, thereby reducing manpower in the paper card tray 200 preparation process and improving the forming efficiency of the paper card tray 200. The paper card tray 200 includes a first sub-part 201 and a folding part 202 that are folded together. In the initial state, the first sub-part 201 and the folding part 202 are connected to each other and are on the same plane. After the paper card tray 200 is formed, the first sub-part 201 and the folding part 202 are folded together, forming a preset angle between them. The forming equipment 100 includes a support member 10, a first forming member 20, and a second forming member 30. Through the cooperation between the support member 10, the first forming member 20, and the second forming member 30, the first sub-part 201 and the folding part 202 are folded together to form a preset angle, thus completing the preparation of the paper card tray 200. The support member 10 is used to support and carry the paper tray 200. The support member 10 includes a first support portion 11 and a second support portion 12 connected in the first direction X. The first support portion 11 has a first support surface M1 in the second direction Y, and the second support portion 12 has a first top surface M2 in the second direction Y. The second support portion 12 protrudes from the first support portion 11 in the second direction Y and includes a second support surface M3 connecting the first top surface M2 and the first support surface M1. When the paper tray 200 is supported and carried by the support member 10, the first support portion 11 is supported on the first sub-part 201, and the first sub-part 201 partially contacts the first support surface M1. The second support portion 12 is supported on the folding portion 202, and the folding portion 202 partially contacts the first top surface M2 and the second support surface M3. At the connection point between the first support surface M1 and the second support surface M3, corresponding to the connection point between the first sub-part 201 and the folding part 202 in the paper card tray 200, there is a gap between the paper card tray 200 and the support member 10. The first forming member 20 overlaps with the first support surface M1 in the second direction Y, and the first forming member 20 slides relative to the support member 10 in the second direction Y. When the paper card tray 200 is supported and carried by the support member 10, the first forming member 20 slides along the second direction Y towards the side closer to the first support surface M1 and contacts the first sub-part 201 in the paper card tray 200. Under the action of the first forming member 20, the first sub-part 201 is fitted to the first support surface M1. Under the self-inertia between the first sub-part 201 and the folding part 202 in the paper card tray 200, the folding part 202 is also fitted to the second support surface M3, and an initial angle is formed between the first sub-part 201 and the folding part 202. The second molded part 30 is located on the side of the first top surface M2 away from the first support surface M1 in the second direction Y, and on the side of the second support part 12 away from the first support part 11 in the first direction X. The second molded part 30 is slidably disposed relative to the support part 10 along the first direction X.When the second forming member 30 slides relative to the support member 10 along the first direction X, the second forming member 30 can contact the end of the folding part 202 away from the first sub-part 201, and drive the end of the folding part 202 away from the first sub-part 201 to fold further, thereby further consolidating and reducing the folding angle between the folding part 202 and the first sub-part 201, so as to ensure that after the surrounding restricting structure is removed, the first sub-part 201 and the folding part 202 can still have a preset folding angle after a certain degree of elastic recovery, so as to realize the forming of the paper card tray 200.

[0055] In some embodiments, please refer to Figures 1 to 4 The forming device 100 has a first state in which the paper tray 200 is sandwiched between the first forming member 20 and the support member 10, and in the second direction Y, the first forming member 20 and the second forming member 30 partially overlap. The first forming member 20 includes a first body portion 21 and a first protrusion 22 protruding from the first body portion 21 toward the side facing the second forming member 30. The second forming member 30 includes a second body portion 31 and a second protrusion 32 protruding from the second body portion 31 toward the side facing the first forming member 20. The second protrusion 32 is larger in the first direction X than the first protrusion 22 in the first direction X, and in the second direction Y, the second protrusion 32 is located on the side of the first protrusion 22 away from the first support surface M1.

[0056] In the molding apparatus 100 provided in this application embodiment, the first molding member 20 slides relative to the support member 10 along the second direction Y, and the second molding member 30 slides relative to the support member 10 along the first direction X. The relative positional relationship between the first molding member 20 and the second molding member 30 can change. The molding apparatus 100 includes a first state, which is the state structure when the first molding member 20 is in a specific position and the second molding member 30 is in a specific position. In the first state, the paper card holder 200 is sandwiched between the first molding member 20 and the support member 10. That is, in the first state, due to the action of the first molding member 20, the first sub-part 201 is in contact with the first support surface M1, and the folded part 202 is in contact with the second support surface M3. In the first state, the first molding member 20 and the second molding member 30 are partially overlapped in the second direction Y. That is, during the sliding of the second molding member 30 along the first direction X, a portion of the structure of the second molding member 30 overlaps with the first molding member 20 to consolidate the included angle between the folded part 202 and the first sub-part 201.

[0057] Specifically, the first molded part 20 includes a first body portion 21 and a first protrusion 22 protruding from the first body portion 21 towards the second molded part 30. The first protrusion 22 is disposed opposite to the end of the first molded part 20 near the support member 10. The second molded part 30 includes a second body portion 31 and a second protrusion 32 protruding from the second body portion 31 towards the first molded part 20. The second protrusion 32 is disposed opposite to the end of the second molded part 30 away from the support member 10. During the further folding process of the folding part 202, the folding part 202 first contacts the recessed position on the second molded part 30, that is, the position on the second body portion 31 that is offset from the second protrusion 32. Then, under the action of the second molded part 30, the folding part 202 contacts and is disposed with the first protrusion 22. In order to avoid damage to the folding part 202 by the first molded part 20 and the second molded part 30 during the folding process, a space of a certain size is formed between the first molded part 20 and the second molded part 30, and the folding part 202 is located inside this space.

[0058] Specifically, the second protrusion 32 is larger in the first direction X than the first protrusion 22 in the first direction X. In the second direction Y, the second protrusion 32 is located on the side of the first protrusion 22 facing away from the first support surface M1. During the sliding of the second molded part 30 along the first direction X, the second protrusion 32 is on the side of the second body part 31 facing the first molded part 20. The second protrusion 32 first contacts the first molded part 20. Since the second protrusion 32 is misaligned with the first protrusion 22 in the second direction Y, the second protrusion 32 will contact the first body part 21 in the first molded part 20. After the second protrusion 32 contacts the first body part 21, the second protrusion 32 and the first protrusion 22 overlap and are misaligned in the second direction Y. Since the second protrusion 32 is larger than the first protrusion 22 in the first direction X, a gap still exists between the first protrusion 22 and the second body part 31 after the second protrusion 32 contacts the first body part 21, and the folded part 202 is located inside this gap. This arrangement allows the folded part 202 to fold further, thus reinforcing the angle between the folded part 202 and the first sub-part 201, while also creating a certain gap to allow for some movement of the folded part 202, thereby reducing the probability of damage to the folded part 202 caused by the first molding part 20 and the second molding part 30.

[0059] In some embodiments, please refer to Figures 1 to 4 The first protrusion 22 includes a first limiting surface M4 that is away from the first support surface M1 in the second direction Y. In the direction parallel to the first direction X and gradually away from the first body part 21, the distance between the first limiting surface M4 and the first support surface M1 in the second direction Y gradually decreases.

[0060] During the further folding of the folding portion 202, the first molding part 20 presses the first sub-part 201 against the first support surface M1 on the first support part 11. The side of the first protrusion 22 facing the first support surface M1 is flush with the side of the first body part 21 facing the first support surface M1, and the first body part 21 and the first protrusion 22 press the first sub-part 201 together. When the position of the first sub-part 201 is fixed, when the folding portion 202 is folded, the folding portion 202 folds along an arc trajectory with its connection point with the first sub-part 201 as the center, and the folding portion 202 is tilted during the folding process.

[0061] During the folding process, the folded portion 202 folds to the side of the first protrusion 22 that is away from the first support surface M1. To reduce damage to the folded portion 202 caused by the first protrusion 22, the first protrusion 22 includes a first limiting surface M4 that is away from the first support surface M1 in the second direction Y. In a direction parallel to the first direction X and gradually moving away from the first body portion 21, the distance between the first limiting surface M4 and the first support surface M1 gradually decreases in the second direction Y. During the folding process of the folded portion 202, the inclined arrangement of the first limiting surface M4 can reduce the contact force between the first limiting surface M4 and the folded portion 202, thereby reducing damage to the folded portion 202 caused by the first protrusion 22. Even if the folded portion 202 comes into contact with the first limiting surface M4, since the distance between the first limiting surface M4 and the first supporting surface M1 gradually decreases in the second direction Y, the connection position between the first limiting surface M4 and the first supporting surface M1 can correspond to the connection position between the folded portion 202 and the first sub-part 201. This allows the folded portion 202 to form a planar contact even when it is in contact with the first limiting surface M4, thus reducing damage to the folded portion 202.

[0062] In some embodiments, please refer to Figures 1 to 4 The second body part 31 includes a second limiting surface M5 on the side facing the first molded part 20 along the first direction X. The second limiting surface M5 is connected to the second protrusion 32. In a direction parallel to the second direction Y and gradually away from the second protrusion 32, the distance between the second limiting surface M5 and the first molded part 20 in the first direction X gradually increases.

[0063] To reduce damage to the folded portion 202 during contact between the second molded part 30 and the folded portion 202, the contact point between the second molded part 30 and the folded portion 202 is also set as an inclined surface. By setting the contact point as an inclined surface, the contact force of the second molded part 30 on the folded portion 202 is reduced. During the sliding process of the second molded part 30, the folded portion 202 contacts the second body part 31 at a position offset from the second protrusion 32. The second body part 31 includes a second limiting surface M5 on the side facing the first molded part 20 along the first direction X. The second limiting surface M5 is connected to the second protrusion 32. In the direction parallel to the second direction Y and away from the second protrusion 32, the distance between the second limiting surface M5 and the first molded part 20 in the first direction X gradually increases.

[0064] During the sliding process of the second molded part 30, the second limiting surface M5 contacts the folded part 202 and drives the folded part 202 to fold further. Based on the inclined setting of the second limiting surface M5, a relatively gentle contact force can be formed during the contact with the folded part 202, reducing damage to the folded part 202. Furthermore, in conjunction with the inclined setting of the first limiting surface M4, the second limiting surface M5 is inclined in the same direction as the first limiting surface M4, which can limit the folding of the folded part 202 to a certain extent, so as to consolidate the folding angle of the folded part 202 relative to the first sub-part 201.

[0065] Preferably, the angle between the first limiting surface M4 and the first supporting surface M1 is smaller than the angle between the second limiting surface M5 and the first supporting surface M1. After the second protrusion 32 contacts the first body part 21, the gap between the first limiting surface M4 and the second limiting surface M5 in the first direction X gradually decreases in the direction away from the first supporting surface M1 along the second direction Y. This reduces damage to the connection position between the folded part 202 and the first sub-part 201 while forming a good limit on the end of the folded part 202 away from the first sub-part 201, thereby consolidating and strengthening the folding angle between the folded part 202 and the first sub-part 201.

[0066] In some embodiments, please refer to Figures 1 to 4 In a direction parallel to the second direction Y and gradually moving away from the first support part 11, the distance between the second support surface M3 and the first support surface M1 in the first direction X gradually increases.

[0067] As the first molded part 20 slides towards the first support surface M1 along the first direction X, it presses the first sub-part 201 against the first support surface M1. The folded part 202 adheres to the second support surface M3 based on the inertia of the paper tray 200. To reduce damage to the folded part 202 from the second support surface M3 during this process, the second support surface M3 is tilted. An obtuse angle is formed between the first support surface M1 and the second support surface M3, so that the folded part 202 can gently adhere to the second support surface M3 during the downward pressing of the first sub-part 201, reducing friction between the second support surface M3 and the folded part 202, thereby reducing damage to the folded part 202 from the second support surface M3.

[0068] In some embodiments, please refer to Figures 1 to 4 The paper tray 200 also includes a second sub-part 203 folded and connected to the folding portion 202 on the side away from the first sub-part 201. The folding portion 202 includes a first folding segment 2021 folded and connected to the first sub-part 201, a second folding segment 2022 folded and connected to the first folding segment 2021 on the side away from the first sub-part 201, and a third folding segment 2023 folded and connected to the second folding segment 2022 on the side away from the first folding segment 2021. The third folding segment 2023 is folded and connected to the second sub-part 203. The second sub-part 203 is stacked and fixedly connected to the first sub-part 201. The folding segment and part of the structure of the first sub-part 201 can be folded to form a rectangular frame structure.

[0069] In related technologies, to enhance the protective effect of the paper tray 200 on the product, the paper tray 200 can be configured with a double-layer structure, forming a rectangular frame structure to further reduce the vibration of the product. Specifically, the paper tray 200 includes a second sub-part 203 folded and connected to the side of the folding portion 202 away from the first sub-part 201. The second sub-part 203 can be folded through the folding portion 202 to contact the first sub-part 201 and be fixedly connected to it. The folding portion 202 includes a first folding segment 2021, a second folding segment 2022, and a third folding segment 2023 folded and connected, and combined with part of the structure of the first sub-part 201, the folding portion 202 can form a rectangular frame structure. For example, a portion of the structure of the first sub-part 201 extends horizontally. The first folding segment 2021 is folded 90 degrees counterclockwise relative to the first sub-part 201 and extends vertically. The second folding segment 2022 is folded 90 degrees counterclockwise relative to the first folding segment 2021 and extends horizontally. The third folding segment 2023 is folded 90 degrees counterclockwise relative to the second folding segment 2022 and extends vertically. The second sub-part 203 is folded 90 degrees clockwise relative to the third folding segment 2023 and extends horizontally. Both the second sub-part 203 and the first sub-part 201 extend horizontally and are fixedly connected at their overlapping portion. The included angle between the folding segments in the folding part 202 can vary, forming either a rectangular frame structure or a planar structure. In the initial state of the paper tray 200, the folding part 202 has a planar structure to facilitate the transportation of the paper tray 200. After the paper tray 200 is formed, the folding part 202 forms a rectangular frame structure to facilitate the protection of the product.

[0070] In the aforementioned paper card tray 200, please refer to Figures 1 to 4 A first crease is formed at the connection between the first sub-part 201 and the folded part 202, and the first sub-part 201 and the folded part 202 are folded together along the first crease. A second crease is formed at the connection between the second sub-part 203 and the folded part 202, and the second sub-part 203 and the folded part 202 are folded together along the second crease. When the paper tray 200 is supported by the support member 10, the first crease corresponds to the connection position between the first support surface M1 and the second support surface M3. The first forming member 20 is located on the side of the second crease away from the folded part 202, and the first forming member 20 can slide along the second direction Y to contact the second sub-part 203.

[0071] The first molding part 20 and the second support part 12 are spaced apart in the first direction X, and the distance between the first molding part 20 and the second support part 12 in the first direction X is not less than the size of the second folding segment 2022 in the direction from the first folding segment 2021 to the third folding segment 2023.

[0072] When the forming setting is used to form a paper card holder 200 capable of forming a rectangular frame structure, space needs to be reserved for the folding portion 202 to form the rectangular frame structure. In the above rectangular frame, the second folding segment 2022 extends along the horizontal plane between folds. To facilitate the forming of the rectangular frame structure, the first forming member 20 and the second support portion 12 are spaced apart in the first direction X. The space between the first forming member 20 and the second support portion 12 in the first direction X is not less than the size of the second folding segment 2022 in the direction from the first folding segment 2021 to the third folding segment 2023, so as to reserve the size of the second folding segment 2022 when folded to the horizontal plane, ensuring that the folding portion 202 can smoothly form a rectangular frame structure. Optionally, the side of the first forming member 20 facing the second support portion 12 can be correspondingly set with the second crease, which facilitates the folding of the folding portion 202 while also stably fixing the position of the first sub-part 201 and the second sub-part 203 relative to the first support surface M1.

[0073] In the second support surface M3, the distance between the first end and the second end is greater than the extension dimension of the first folding segment 2021. During the sliding process of the second molding part 30, the second molding part 30 contacts the first folding segment 2021 and drives the first folding segment 2021 to fold, thereby driving the second folding segment 2022 and the third folding segment 2023 to fold, so that the folding part 202 and part of the first sub-part 201 form a rectangular frame structure.

[0074] In some embodiments, please refer to Figure 1 and Figure 5 The molding equipment 100 also includes a limiting component 40, which includes a first limiting member 41 located on the side of the first support portion 11 away from the second support portion 12 along the first direction X. The first limiting member 41 protrudes from the first support portion 11 in the second direction Y.

[0075] During the sliding of the first forming member 20 along the second direction Y, the first forming member 20 exerts a downward pressure on the paper card tray 200. After the support member 10 supports and bears the paper card tray 200, since the second support part 12 protrudes from the first support part 11, there is a probability that the paper card tray 200 may shift away from the second support part 12 during the downward pressure process. In order to improve the positional stability of the paper card tray 200 on the support member 10, the forming device also includes a limiting component 40. The limiting component 40 includes a first limiting member 41, which is located on the side of the first support part 11 away from the second support part 12 along the first direction X. The first limiting member 41 protrudes from the first support part 11 in the second direction Y, and the first limiting member 41 and the second support part 12 protrude from the same side of the first support part 11.

[0076] After the support member 10 supports and carries the paper card tray 200, the end of the paper card tray 200 facing the first limiting member 41 contacts the first limiting member 41. During the pressing process, the first limiting member 41 limits the paper card tray 200 to ensure the positional correspondence between the first sub-part 201 and the first support surface M1, and the positional correspondence between the folding part 202 and the second support surface M3.

[0077] Optionally, the limiting component 40 further includes a second limiting member and a third limiting member disposed on both sides of the support member 10 along the third direction Z. After the support member 10 supports and carries the paper card tray 200, the paper card tray 200 contacts the second limiting member and the third limiting member on both sides along the third direction Z, respectively. The second limiting member and the third limiting member limit the paper card tray 200 in the third direction Z to ensure the relative positional relationship of the paper card tray 200 on the support member 10.

[0078] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The forming equipment 100 also includes a transfer component 50 and a storage component 60. The storage component 60 is located on the side of the support member 10 away from the second forming member 30 along the first direction X. The transfer component 50 includes a first transfer member 51 and a second transfer member 52, which are slidably disposed along the first direction X. The first transfer member 51 is used to transfer the paper card tray 200 to be formed onto the support member 10, and the second transfer member 52 is used to transfer the formed paper card tray 200 on the support member 10 to a subsequent station.

[0079] The forming device 100 in this embodiment further includes a transfer component 50 and a storage component 60. The storage component 60 is used to store the unformed paper tray 200, and the transfer component 50 is used to transfer the paper tray 200 to realize an automated process for the preparation and forming of the paper tray 200.

[0080] Considering the relative fit between the support member 10, the first molding member 20 and the second molding member 30, in order to reduce the probability of structural interference between the storage component 60 and the second molding member 30, the storage component 60 is positioned on the side of the support member 10 away from the second molding member 30 along the first direction X.

[0081] During the fabrication of the paper card tray 200, it is necessary to transfer the unformed paper card tray 200 to the support member 10, and also to transfer the formed paper card tray 200 to the subsequent processing station. To improve the transfer efficiency of the transfer assembly 50, the transfer assembly 50 includes a first transfer member 51 and a second transfer member 52. The first transfer member 51 is used to transfer the unformed paper card tray 200 onto the support member 10, and the second transfer member 52 is used to transfer the formed paper card tray 200 from the support member 10 to the subsequent processing station. Considering that the storage assembly 60 and the support member 10 are spaced apart along the first direction X, the first transfer member 51 and the second transfer member 52 are slidably arranged along the first direction X. Optionally, to improve the sliding reliability of the first transfer member 51 and the second transfer member 52, a slide rail can also be provided, and the first transfer member 51 and the second transfer member 52 can be connected to the same slide rail.

[0082] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The storage component 60 includes a storage member 61, which has a storage cavity inside for storing a paper tray 200 to be formed. The storage member 61 has a through-hole structure that extends through the storage cavity along a first direction X. The storage component 60 also includes a pusher 62 that is slidably disposed on the frame 70 along the first direction X. The projection of the pusher 62 in the first direction X is located inside the projection of the through-hole structure in the first direction X. At least a portion of the pusher 62 can slide into the through-hole structure to push the paper tray 200 to the outside of the storage cavity.

[0083] In the storage component 60, multiple paper trays 200 are stacked vertically. During the transmission process of the first transmission member 51, the vertical height of the support member 10 may be lower than the height of the tallest paper tray 200 in the storage component 60. To facilitate the transmission by the first transmission member 51, the structure of the storage component 60 is specifically configured to transfer the paper trays 200 that need to be transmitted by the first transmission member 51 to the outside of the storage component 60, thereby facilitating the first transmission member 51 to transmit the paper trays 200 to the support member 10.

[0084] The storage component 60 includes a storage element 61, which forms a storage cavity. Multiple paper card trays 200 are stacked within the storage cavity. The storage element 61 has a through-hole structure extending along a first direction X, communicating with the storage cavity. The storage component 60 also includes a pusher 62 that slides along the first direction X, passing through the through-hole structure. When paper card trays 200 are stacked at the through-hole structure, the pusher 62 can push the paper card trays 200 out of the storage cavity and to a specific position to facilitate transmission by the first transmission element 51. The sliding of the pusher 62 can be driven by a third driving element, which can be a cylinder.

[0085] In some embodiments, please refer to Figure 1 and Figure 5 At least two sets of support members 10, first molding members 20 and second molding members 30 are provided. At least two sets of support members 10, first molding members 20 and second molding members 30 are arranged side by side along the third direction Z. The third direction Z, the second direction Y and the first direction X intersect each other.

[0086] To improve the forming efficiency of the forming equipment 100 for the paper card tray 200, two sets of support members 10, first forming members 20 and second forming members 30 can be provided. Based on the cooperation relationship between the support members 10, first forming members 20 and second forming members 30, at least two sets of support members 10, first forming members 20 and second forming members 30 are arranged side by side along the third direction Z. At least two sets of support members 10, first forming members 20 and second forming members 30 can simultaneously form and prepare the paper card tray 200, so as to improve the forming efficiency of the paper card tray 200.

[0087] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
