Description

Technical Field

[0001] This utility model belongs to the technical field of cardboard box processing equipment, and in particular relates to a cardboard box bonding and pressure holding machine. Background Technology

[0002] When producing cardboard boxes, after cutting and folding to create creases, they need to be folded into a box structure. At the folded joints, glue is usually applied and then bonded. Since the glue needs time to cure, the box is usually subjected to pressure while waiting for the glue to solidify. Therefore, we urgently need to design a machine that can be used for pressure holding of cardboard boxes to assist in production. Utility Model Content

[0003] The purpose of this invention is to provide a carton bonding and pressing machine to solve the problems mentioned in the background art.

[0004] In view of this, the present invention provides a bonding and pressing machine for cardboard boxes, comprising:

[0005] frame;

[0006] The positioning mechanism is provided in multiple sets. The positioning mechanism is movable up and down on the frame. The positioning mechanism is used to be covered by the carton, and the shape of the positioning mechanism is adapted to the carton.

[0007] A motion mechanism is connected and disposed between the frame and the positioning mechanism to restrict the vertical up-and-down movement of the positioning mechanism along the frame;

[0008] A buffer mechanism is connected and disposed between the frame and the positioning mechanism, and the buffer mechanism is used to generate an elastic buffering force in the up-down movement direction of the positioning mechanism;

[0009] A pressure-holding mechanism is provided on the frame and positioned above the positioning mechanism. The pressure-holding mechanism is used to move vertically up and down to push against the upper surface of the carton so that the bottom of the positioning mechanism is pressed against the frame, thereby keeping the glued parts of the carton in place and maintaining pressure.

[0010] In this embodiment, a further implementation is that the positioning mechanism includes a positioning frame, which has a rectangular frame structure. One side of the positioning frame is slidably connected to the machine frame through a motion mechanism, and the carton is inserted into the positioning frame from the side of the positioning frame away from the motion mechanism.

[0011] In this embodiment, a further implementation is that the motion mechanism includes a guide rail and a slider. The slider is vertically fixed on the side of the positioning frame, the guide rail is fixed on the positioning frame, and the slider is slidably connected to the guide rail, so that the positioning frame moves up and down.

[0012] In this embodiment, a further implementation is that the frame is provided with a base plate, which is directly below the positioning frame. The buffer mechanism includes a limiting shaft and a buffer spring. The limiting shaft is vertically fixed on the base plate and slides through a limiting block on one side of the positioning frame. The buffer spring is sleeved on the limiting shaft and its two ends elastically abut against the bottom surface of the limiting block and the top surface of the base plate, respectively. The buffer mechanism and the motion mechanism are on the same side of the positioning frame.

[0013] In this embodiment, a further implementation is that the pressure-holding mechanism includes a cylinder, a support plate, a push plate, and a connecting plate. The top of the frame is a top frame, the support plate is fixed to the top of the top frame, the cylinder is fixed to the upper part of the support plate, and the output end of the cylinder passes through the support plate. The connecting plate is fixedly connected to the output end of the cylinder, the push plate is fixed to the bottom surface of the connecting plate, and the push plate is used to press the upper surface of the carton onto the positioning frame. A guide rod is also provided between the connecting plate and the support plate, the bottom end of the guide rod is fixedly connected to the connecting plate, and the guide rod is slidably connected to the support plate.

[0014] In this embodiment, a further implementation is that a pressure plate is fixed to the upper edge of the base plate, and when the positioning frame is pressed down into place, the lower surface of the carton just touches the glued area of ​​the upper edge of the pressure plate.

[0015] The beneficial effects of this utility model are:

[0016] The machine frame is equipped with multiple positioning mechanisms, which can simultaneously process multiple cartons under pressure, improving output and efficiency. After applying glue to the glued joints of the cartons, the cartons are initially folded into the shape of a box. Then, the cartons are inserted into the positioning frame from one side. The pressure-holding mechanism is activated, causing it to move downwards and press down on the upper surface of the cartons. Gradually, the positioning mechanism is pushed down along the moving mechanism. At this time, the buffer mechanism stores elastic potential energy until the cartons are pushed into place. The bottom edge of the cartons adheres to the upper surface of the pressure plate and is held under pressure for a period of time. After the glue has solidified and the cartons are fully formed, the cylinder moves in the opposite direction, and the buffer mechanism quickly resets the positioning frame. After the positioning frame leaves the pressure plate, the cartons can be removed. The overall machine structure is simple, easy to operate, and reliably completes the pressure-holding work for cartons. Attached Figure Description

[0025] This embodiment provides a cardboard box bonding and pressure holding machine, including:

[0026] Rack 1;

[0027] Positioning mechanism 2, multiple sets are provided, and four sets are preferred in this embodiment. The positioning mechanism 2 can be movably mounted on the frame 1. The positioning mechanism 2 is used to be covered by the carton 3, and the shape of the positioning mechanism 2 is adapted to the carton 3. The carton 3 is first brushed with glue at the fold and then inserted from one side of the positioning mechanism 2.

[0028] Motion mechanism 4 is connected and disposed between the frame 1 and the positioning mechanism 2 to restrict the vertical up-and-down movement of the positioning mechanism 2 along the frame 1;

[0029] A buffer mechanism 5 is connected between the frame 1 and the positioning mechanism 2. The buffer mechanism 5 is used to generate elastic buffering force in the up and down movement direction of the positioning mechanism 2, which helps to quickly reset the positioning mechanism 2 after the pressure holding is completed.

[0030] The pressure holding mechanism 6 is located on the frame 1 and positioned above the positioning mechanism 2. The pressure holding mechanism 6 is used to move vertically up and down to push against the upper surface of the carton 3 so that the bottom of the positioning mechanism 2 is pressed against the frame 1, so that the glued parts on the carton 3 are adhered and pressure is maintained. After a period of time, the carton 3 is fully formed after the glue has solidified.

[0031] In this embodiment, a further implementation is that the positioning mechanism 2 includes a positioning frame 20, which has a rectangular frame structure. One side of the positioning frame 20 is slidably connected to the frame 1 through the motion mechanism 4. The carton 3 is fitted onto the positioning frame 20 from the side of the positioning frame 20 away from the motion mechanism 4. The length, width and height of the positioning frame 20 are designed to match the actual size of the carton 3. Of course, different sizes of positioning frames 20 can be replaced for different sizes of carton 3.

[0032] In this embodiment, the motion mechanism 4 further includes a guide rail 40 and a slider 41. The slider 41 is vertically fixed on the side of the positioning frame 20, and the guide rail 40 is fixed on the positioning frame 20. The slider 41 is slidably connected to the guide rail 40, so that the positioning frame 20 can move up and down, and the guide rail 40 can only slide on the slider 41 without falling off, thus limiting the positioning frame 20 to only vertical up and down movement.

[0033] In this embodiment, the frame 1 is further provided with a base plate 10, which is directly below the positioning frame 20. The buffer mechanism 5 includes a limiting shaft 50 and a buffer spring 51. The limiting shaft 50 is vertically fixed on the base plate 10 and slides through the limiting block 200 on one side of the positioning frame 20. The buffer spring 51 is sleeved on the limiting shaft 50 and its two ends elastically abut against the bottom surface of the limiting block 200 and the top surface of the base plate 10, respectively. The buffer mechanism 5 and the motion mechanism 4 are on the same side of the positioning frame 20. During the up-and-down movement of the positioning frame 20, the limiting shaft 50 mainly limits the vertical freedom of the positioning frame 20, and the buffer spring 51 extends and retracts to facilitate the automatic reset of the positioning frame 20.

[0034] In this embodiment, the pressure-holding mechanism 6 further includes a cylinder 60, a support plate 61, a push plate 62, and a connecting plate 63. The top of the frame 1 is a top frame 11, the support plate 61 is fixed to the top of the top frame 11, the cylinder 60 is fixed to the upper part of the support plate 61, and the output end of the cylinder 60 passes through the support plate 61. The connecting plate 63 is fixedly connected to the output end of the cylinder 60. The push plate 62 is fixed to the bottom surface of the connecting plate 63. The push plate 62 is used to press the upper surface of the carton 3 against the positioning frame 20. A guide rod 64 is also provided between the connecting plate 63 and the support plate 61. The bottom end of the guide rod 64 is fixedly connected to the connecting plate 63, and the guide rod 64 is slidably connected to the support plate 61. After the carton 3 is fitted onto the positioning frame 20, the cylinder 60 pushes the push plate 62 to press against the upper surface of the carton 3, and continues to push the positioning frame 20 downward. In order to ensure that the glued area at the bottom of the carton 3 can also be pressed down, a pressure plate 100 is fixed to the edge of the upper surface of the base plate 10. When the positioning frame 20 is pressed down into place, the lower surface of the carton 3 just touches the glued area at the edge of the upper surface of the pressure plate 100. After the pressure is maintained for a period of time, and the glue solidifies and the carton 3 is fully formed, the cylinder 60 moves in the opposite direction, and the buffer mechanism 5 quickly resets the positioning frame 20. After the positioning frame 20 leaves the pressure plate 100, the carton 3 can be taken out. The overall machine structure is simple, the operation is convenient, and it reliably completes the pressure maintenance work of the carton 3.

This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
