Description

Technical Field

[0001] The invention belongs to the technical field of paper barrel packaging, and more specifically, particularly relates to an automatic opening and closing mold device for a paper barrel roll. Background Art

[0002] The reel machine currently used in the Chinese market is a mechanical equipment designed on the basis of a foreign one in 1987. The reel mold is divided into four pieces, one of which is connected to the handle through an eccentric wheel. When the handle is turned, the eccentric wheel lifts up the movable block to expand the mold into a circle. When the handle is turned in the opposite direction, the movable block returns under the action of the spring, and the diameter of the reel mold becomes smaller. Therefore, before reeling, it is necessary to manually close the reel mold through the handle to increase the diameter of the mold, and then manually wrap the glued paper tape around the rotating reel mold and press it tightly. After reeling, the handle is used to reduce the diameter of the rotating mold to facilitate the removal of the processed paper barrel.

[0003] Based on the above, the inventors have found the following problems: the existing roll mold is easy to get stuck when opening and closing, and is unstable, which leads to pauses when installing and removing the roll, affecting work efficiency, and the existing roll mold is easy to deform after long-term use, and the mold needs to be replaced frequently.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a paper barrel roll automatic opening and closing mold device is provided, in order to achieve a more practical purpose. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an automatic opening and closing mold device for a paper barrel roll, so as to solve the problems that the current roll mold is easy to get stuck and unstable when opening and closing, resulting in pauses when the paper roll is rolled and the roll is removed, affecting work efficiency, and is easy to deform after long-term use, requiring frequent mold replacement.

[0006] The present invention provides a paper barrel roll automatic opening and closing mold device, which is achieved by the following specific technical means:

[0007] A paper barrel roll automatic opening and closing mold device comprises a first shell and a second shell, a first connecting plate is fixed to one end of the first shell away from the second shell, a second connecting plate is fixed to one end of the second shell away from the first shell, a first support block is fixed to the bottom of the inner wall of the first shell, first connecting rods are fixed to both ends of the top of the first support block, guide rails are fixed to both ends of the top of the first connecting rod, a second support block is fixed to the bottom of the inner wall of the second shell, second connecting rods are fixed to both ends of the bottom of the second support block, a sliding rail is fixed to the bottom of the second connecting rod, the sliding rail is slidably connected to the guide rail, a support rod is fixed to one end of the second connecting plate, a spring is movably sleeved on the outer wall of the support rod, and the other end of the support rod is fixed to the second support block.

[0008] Furthermore, a height value of the first connecting plate close to one end of the first shell is greater than a height value of the other end of the first connecting plate, and a height value of the second shell close to one end of the second connecting plate is greater than a height value of the other end of the second shell.

[0009] Furthermore, the slide rail and the guide rail are arranged in an inclined state, and the vertical cross-section of the slide rail is in an I-shape.

[0010] Furthermore, three second support blocks are provided, and the height values ​​of the three second support blocks increase stepwise from left to right; three first support blocks are provided, and the height values ​​of the three first support blocks decrease stepwise from left to right.

[0011] Furthermore, a limiting block is fixed on one end of the first connecting plate close to the second connecting plate and away from the first shell, and the limiting block and the second supporting block are located in the same horizontal plane.

[0012] Furthermore, a connector is fixed at the middle of one end of the first connecting plate, and the connector is used to be connected to an external pneumatic telescopic rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the first shell and the second shell are separated at an inclination toward both ends, and the thickness of the middle part of the first shell and the second shell becomes shorter, so that the wound paper barrel can be conveniently removed, and the elastic potential energy is released by the spring, so that when not subjected to external force, the first shell and the second shell are in a completely closed state, so that the roll can be better limited, and then the paper is rolled on the outer wall of the mold. After the paper is rolled, the first shell and the second shell are continuously controlled to separate at an inclination toward both ends, and when the paper is removed, the slide rail and the guide rail slide the first shell and the second shell to slide more smoothly, thereby achieving the effect of reducing the frequency of the mold getting stuck when opening and closing, and making the mold open and close more smoothly.

[0015] 2. In the present invention, the second connecting rod is connected to the second shell by three second supporting blocks, and the first connecting rod is connected to the first shell by three first supporting blocks, so that the first shell and the second shell have better support and the possibility of deformation due to external force is reduced, thereby achieving the effect of making the mold more durable, reducing deformation and increasing service life.

[0026] The present invention provides an automatic opening and closing mold device for a paper barrel roll, comprising a first shell 1 and a second shell 13, wherein a first connecting plate 2 is fixed to one end of the first shell 1 away from the second shell 13, and a second connecting plate 12 is fixed to one end of the second shell 13 away from the first shell 1, a first supporting block 4 is fixed to the bottom of the inner wall of the first shell 1, first connecting rods 5 are fixed to both ends of the top of the first supporting block 4, and guide rails 6 are fixed to both ends of the top of the first connecting rod 5, a second supporting block 9 is fixed to the bottom of the inner wall of the second shell 13, second connecting rods 8 are fixed to both ends of the bottom of the second supporting block 9, a slide rail 7 is fixed to the bottom of the second connecting rod 8, and the slide rail 7 is slidably connected to the guide rail 6, a supporting rod 10 is fixed to one end of the second connecting plate 12, a spring 11 is movably sleeved on the outer wall of the supporting rod 10, and the other end of the supporting rod 10 is fixed to the second supporting block 9, two springs 11 and supporting rods 10 are respectively arranged on both sides of the middle part of the second connecting plate 12, and elastic potential energy is released by the spring 11, so that when no external force is applied, the first shell 1 and the second shell 2 are in a completely closed state, and the roll can be better limited.

[0027] Among them, the height value of the first connecting plate 2 close to one end of the first shell 1 is greater than the height value of the other end of the first connecting plate 2, and the height value of the second shell 13 close to one end of the second connecting plate 12 is greater than the height value of the other end of the second shell 13, so that when the first shell 1 and the second shell 2 are tilted and separated at both ends, the distance between the outer contours of the first shell 1 and the second shell 2 becomes shorter, and the reel can be easily removed or installed.

[0028] The slide rail 7 and the guide rail 6 are arranged in an inclined shape, and the vertical section of the slide rail 7 is an I-shape, so that when the first shell 1 and the second shell 2 are separated toward both ends, the middle parts of the first shell 1 and the second shell 2 move toward the center.

[0029] Among them, three second support blocks 9 are provided, and the height values ​​of the three second support blocks 9 increase in steps from left to right. Three first support blocks 4 are provided, and the height values ​​of the three first support blocks 4 decrease in steps from left to right. The second connecting rod 8 is connected to the second shell 13 through the three second support blocks 9, and the first connecting rod 5 is connected to the first shell 1 through the three first support blocks 4, so that the first shell 1 and the second shell 13 have better support properties and the possibility of external force deformation is reduced.

[0030] Among them, a limiting block 3 is fixed on the first connecting plate 2 close to one end of the second connecting plate 12 and away from the first shell 1. The limiting block 3 and the second supporting block 9 are located in the same horizontal plane. The limiting block 3 is set so that when the first shell 1 and the second shell 13 are separated, the limiting block 3 touches the second supporting block 9 to avoid the separation distance being too large.

[0031] Among them, a connecting head 21 is fixed in the middle of one end of the first connecting plate 2, and the connecting head 21 is used to connect with an external pneumatic telescopic rod, so that the connecting head 21 is connected to the external pneumatic telescopic rod, and the separation and closing of the first shell 1 and the second shell 2 are controlled by the extension and contraction of the pneumatic telescopic rod.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In the present invention, the connector 21 is first connected to the external pneumatic telescopic rod, and the separation and closing of the first shell 1 and the second shell 2 are controlled by the extension and contraction of the pneumatic telescopic rod. When in use, the height value of the second shell 13 close to one end of the second connecting plate 12 is greater than the height value of the other end of the second shell 13, so that when the first shell 1 and the second shell 2 are separated at both ends, the thickness value of the middle part of the first shell 1 and the second shell 2 becomes shorter, and the reel can be easily taken off. The elastic potential energy is released by the spring 11, so that when no external force is applied, the first shell 1 and the second shell 2 are closed. When in a fully closed state, the roll can be better limited, and then the paper is rolled up on the outer wall of the roll. After the paper is rolled up, the first shell 1 and the second shell 2 are controlled to tilt and separate at both ends. When the paper is taken off, the slide rail 7 and the guide rail 6 slide the first shell 1 and the second shell 2 to slide more smoothly, and the second connecting rod 8 is connected to the second shell 13 through three second support blocks 9, and the first connecting rod 5 is connected to the first shell 1 through three first support blocks 4, so that the first shell 1 and the second shell 13 have better support and the possibility of external force deformation is reduced.
