Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, and in particular to a forming device for the connecting part of the frame. Background Technology

[0002] As a common structure in many cardboard boxes, the frame is formed by surrounding gray boards on a mold during the processing. The forming process is generally divided into two steps: first, the gray boards with the face paper pasted on them are surrounded to form the preliminary frame shape; then, the protruding part of the face paper is pasted to the joint of the gray board enclosure to complete the frame forming.

[0003] Because the frame joint is not tightly connected before the face paper protrudes, a pressure plate is used to press the pre-formed frame edge before the face paper protrudes to ensure a firm bond. To prevent the frame edge from moving during the pasting process, the pressure plate needs to remain pressed throughout. However, to avoid movement of the forming components, the pressure plates on the frame forming device can only press a portion of the frame edge and cannot directly press the joint. This results in a loose connection at the frame joint during forming, leading to a problem of loose adhesion when the face paper protrudes, thus reducing the overall quality of the frame. Utility Model Content

[0004] The main purpose of this utility model is to provide a forming device for the connecting parts of the frame, which aims to solve the existing technical problems.

[0005] To achieve the above objectives, this utility model provides a forming device for the connecting part of a frame, including a mold, wherein the a, b, and c sides of the frame are attached to the three sides of the mold, and the d1 end of the d side is protruding, and further includes...

[0006] A pressing element is used to press a portion of the frame a side, and the pressing element is provided with a movable part for pressing the d1 end connection part of the frame a side and the frame d side;

[0007] The forming part is used to form the d1 end of the d side of the frame onto the a side of the frame;

[0008] Before the d1 end of the frame d side is formed, the movable part extends to a position close to the d1 end of the frame d side and presses on the frame a side; during the forming process of the d1 end of the frame d side, the forming part pushes the d1 end of the frame d side to fold towards the frame a side, while the movable part moves backward synchronously.

[0009] Furthermore, the movable part is connected to the elastic element, wherein the movable part passively and synchronously retracts as the molding part pushes.

[0010] Furthermore, the movable part is connected to a linear drive mechanism, wherein the movable part actively and synchronously retracts during the pushing process of the forming part by the linear drive mechanism.

[0011] Furthermore, the movable part and the edge of the frame a are in surface contact or line contact.

[0012] Furthermore, it also includes first clamps on both sides of the forming part, used to pat the connection between the a side and the d side of the frame before the forming part pushes the d1 end of the d side of the frame to form.

[0013] Furthermore, it also includes two second clamping plates for clamping the b and d sides of the frame before the pressing member presses the a side of the frame.

[0014] Furthermore, it also includes a bottom pressure plate, which is used to rise and press the c-side of the frame when the frame is supplied with material.

[0015] Furthermore, the pressing element is controlled to move vertically by a driving mechanism. When the mold moves the frame to the forming position, the pressing element is driven to press the frame a side tightly.

[0016] The beneficial effects of this utility model are reflected in:

[0017] This invention integrates a movable part on the edge pressing component. During the forming process of the d1 end of the frame d side, the movable part continuously applies pressure to the a side of the frame. As the d1 end of the frame d side folds towards the a side of the frame, it simultaneously retracts until the d1 end of the frame d side is fully formed. This ensures that the frame connection remains tightly joined during the forming of the d1 end of the frame d side, improving the tightness of the paper's protruding part during pasting and enhancing the overall forming quality of the frame.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1 This utility model provides a forming device for the joint of a frame, including a mold 100. The a, b, and c sides of the frame are attached to the three sides of the mold 100, and the d1 end of the d side is protruding (it should be noted that the frame is formed by pasting gray board and face paper together, wherein the d1 end of the d side of the frame is the protruding face paper). It also includes...

[0026] The edge clamping member 200 is used to clamp a portion of the frame a side. The edge clamping member 200 is provided with a movable part 300 for clamping the d1 end connection part of the frame a side and the frame d side.

[0027] The forming part 400 is used to form the d1 end of the d side of the frame onto the a side of the frame;

[0028] Before the d1 end of the frame d side is formed, the movable part 300 extends to the position near the d1 end of the frame d side and presses on the a side of the frame; during the forming process of the d1 end of the frame d side, the forming part 400 pushes the d1 end of the frame d side to fold towards the a side of the frame, while the movable part 300 moves backward in sync.

[0029] In this embodiment, when the mold 100 carries the frame material and presses each side of the frame, the forming part 400 pushes the d1 end of the frame d side to fold towards the frame a side. During this process, the movable part 300 moves backward in sync with the forming part 400, always maintaining the pressing on the d1 end of the frame a side near the frame d side until the d1 end of the frame d side is formed. This ensures that the frame connection part remains tightly joined when the d1 end of the frame d side is formed, improving the tightness of the paper's protruding part during pasting and improving the forming quality of the frame.

[0030] In one embodiment, please refer to Figure 2The movable part 300 is connected to the elastic element 301, wherein the movable part 300 passively and synchronously retracts as the molding part 400 pushes. Specifically, the elastic element 301 can be a spring.

[0031] In this embodiment, when the forming part 400 pushes the d1 end of the frame d side to fold towards the frame a side, the forming part 400 comes into contact with the movable part 300. As the forming part 400 moves, it pushes the movable part 300 to passively retreat. During the retreat of the movable part 300, it always maintains pressure on the d1 end of the frame a side near the frame d side, so that the frame connection part remains tightly connected when the d1 end of the frame d side is formed. This improves the tightness of the paper's protruding part when pasting and improves the forming quality of the frame.

[0032] In one embodiment, please refer to Figure 3 The movable part 300 is connected to the linear drive mechanism 302. During the pushing process of the forming part 400, the movable part 300 actively and synchronously retracts under the control of the linear drive mechanism 302. Specifically, the linear drive mechanism 302 can be a pen-shaped cylinder or similar device.

[0033] In this embodiment, when the forming part 400 pushes the d1 end of the frame d side to fold towards the frame a side, the forming part 400 contacts the movable part 300. As the forming part 400 moves, the linear drive mechanism 302 controls the movable part 300 to move backward synchronously, always maintaining pressure on the d1 end of the frame a side near the frame d side. This ensures that the frame connection part remains tightly joined when the d1 end of the frame d side is formed, improving the tightness of the paper's protruding part during pasting and improving the forming quality of the frame.

[0034] In one embodiment, the movable part 300 makes surface contact or line contact with the edge of the frame a. Specifically, the movable part 300 can use a pressure block with a flat bottom to achieve surface contact, or it can use a rotating cylindrical block to achieve line contact.

[0035] In this embodiment, the d1 end of the frame d side is gradually pressed against the frame a side as the forming part 400 pushes it during the forming process. During this process, the movable part 300 can press the d1 end of the frame a side near the frame d side by maintaining surface contact or line contact with the frame a side.

[0036] In one embodiment, please refer to Figure 4 It also includes first clamping plates 500 disposed on both sides of the forming section 400, used to pat the joint between the a side and the d side of the frame before the forming section 400 pushes the d1 end of the frame d side into shape. Specifically, the first clamping plates 500 can be moved by a cylinder.

[0037] In this embodiment, the two first clamping plates 500 are used to tap the connecting parts of the initially formed frame from both sides, so that the two sides of the connecting parts are aligned. This makes the position of the d1 end of the d side of the formed frame more accurate, avoids the problem of positional deviation, and improves the forming quality of the frame.

[0038] In one embodiment, please refer to Figure 4 It also includes two second clamping plates 600, used to clamp the b and d sides of the frame before the pressing member 200 presses the a side of the frame. Specifically, the second clamping plates 600 can be moved by a cylinder.

[0039] In this embodiment, the two second clamping plates 600 press the b and d sides of the frame to ensure that the frame fits the mold 100 better, making the connection of the frame joint more accurate and leaving no gaps, thereby improving the forming quality of the d1 end of the d side of the frame.

[0040] In one embodiment, please refer to Figure 4 It also includes a bottom pressure plate 700, which is used to rise and press against edge c of the frame when the frame material arrives. Specifically, the bottom pressure plate 700 can be raised and lowered by a cylinder.

[0041] In this embodiment, the bottom pressure plate 700 presses the c-side of the frame to ensure that the frame fits the mold 100 better, thereby making the connection of the frame joint more accurate and without gaps, and improving the forming quality of the d1 end of the d-side of the frame.

[0042] In one embodiment, please refer to Figure 4 The pressing element 200 moves vertically under the control of the driving mechanism 800. When the mold 100 moves the frame to the forming position, the pressing element 200 presses the frame a side tightly.

[0043] Specifically, the drive mechanism 800 can be a linear module.

[0044] In this embodiment, the edge pressing component 200 presses the a side of the frame, and together with the bottom pressure plate 700 and the second clamping plate 600, the a, c, b and d sides of the frame are pressed respectively, so that the frame is close to the mold 100, ensuring that the frame joint is neatly connected, thereby improving the forming quality of the d1 end of the d side of the frame.

[0045] It should be noted that in this application, the pressing part 200, the movable part 300, the forming part 400, the first clamping plate 500 and the second clamping plate 600 are all integrated on the same mounting platform. That is, when the driving mechanism 800 controls the pressing part to press the frame a side, the movable part 300, the forming part 400, the first clamping plate 500 and the second clamping plate 600 all move to the working position to wait.

[0046] The specific workflow of this application is as follows: When the frame material arrives, the bottom pressure plate 700 rises and presses the c side of the frame, the drive mechanism 800 controls the above integrated structure to move down as a whole, during the process the pressing edge 200 presses the a side of the frame, the two second clamping plates 600 press and clamp the b and d sides of the frame, the first clamping plates 500 on both sides then pat the connection part of the a side and the d side of the frame, and finally the forming part 400 pushes the d1 end of the d side of the frame to fold towards the a side of the frame to form the frame. During the forming process, the moving part 300 always keeps pressing the d1 end of the a side of the frame close to the d side of the frame until the d1 end of the d side of the frame is formed.
