Description

Technical Field

[0001] The invention relates to the field of rock wool transportation, and in particular to a film hooking mechanism and a packaging body film removing device thereof. Background Art

[0002] Some technical solutions for removing rock wool film have been proposed in the prior art, such as the patent previously applied by our company, whose application number is CN202022539250.6, and whose name is a material grabbing mechanism and its feeding system. In actual use, this technical solution solves the technical problem of grabbing rock wool film and avoids skin damage caused by rock wool to workers; however, two disadvantages were found in actual use: 1. When grabbing rock wool, due to the unreasonable structural design of the grabbing mechanism, the claw hook is embedded too deeply into the rock wool, destroying the structure of the rock wool; 2. When the rock wool film needs to be separated from the grabbing part, the grabbing part rotates in the opposite direction. Since the film is light, it is difficult to separate the glass at one time, and the film needs to be removed manually. In view of this, a new technical solution is needed to solve the above technical problems. Summary of the invention

[0003] In order to solve the above technical problems, the present invention proposes a film hooking mechanism and a packaging film removing device thereof, wherein the present application designs the shape of the hook needle, and the arc-shaped claw hook portion and the rotating portion of the hook needle are coaxially arranged, so that the gap between the claw hook portion and the rotating portion is always equal. When the claw hook portion grabs the rock wool film, as the rotating portion rotates clockwise, the rock wool film will extend into the gap along the arc direction of the gap, which is conducive to the grabbing of the rock wool film, and the rock wool film is not easy to fall off.

[0004] Specifically, the present invention proposes a film hooking mechanism, comprising:

[0005] A mounting portion, wherein the mounting portion is provided with an open slot;

[0006] A rotating part, the rotating part is cylindrical and rotatably disposed in the open slot;

[0007] A hook needle, the hook needle comprising a mounting arm and a claw hook portion, the claw hook portion being fixed to the rotating portion through the mounting arm, the claw hook portion being arc-shaped, the axes of the rotating portion and the claw hook portion being coincident, and a gap being left between a side of the claw hook portion facing the rotating portion and the rotating portion;

[0008] A driving part, wherein the driving part is used to drive the rotating part to rotate.

[0009] The idea of ​​this solution is to propose a technical solution that can effectively grab the rock wool film and reduce the damage to the rock wool. Among them, the application designs the shape of the hook, and the arc-shaped claw hook part and the rotating part of the hook are coaxially arranged, so that the gap between the claw hook part and the rotating part is always equal. When the claw hook part grabs the rock wool film, as the rotating part rotates clockwise, the rock wool film will extend into the gap along the arc direction of the gap, which is conducive to grabbing the rock wool film, and the rock wool film is not easy to fall off.

[0010] In addition, compared with the grab hook in the prior art CN202022539250.6, the technical solution of the present application has the advantages of less damage to the rock wool, simple structure, and not easy to fall off. The above has shown that the rock wool film will extend into the gap along the arc direction of the gap, so a part of the rock wool film is stuck in the gap and is difficult to fall off.

[0011] Furthermore, the claw hook portion is 1 / 4 to 1 / 2 in shape. The claw hook portion can also be set to be 3 / 8 to 7 / 8 in shape. The rock wool film can be effectively grasped, and the grasping efficiency of the claw hook portion is ensured.

[0012] Preferably, the top end of the rotating part along the vertical direction is located above the mounting part, the bottom end of the rotating part along the vertical direction is located below the mounting part, and the distance between the top end of the rotating part and the upper surface of the mounting part is equal to the distance between the bottom end of the mounting part and the lower surface of the mounting part.

[0013] In the initial state, the claw hook is located at the upper end of the rotating part's circumference, and the lower end of the rotating part's circumference is a smooth curved surface. In actual operation, since the rock wool is a block structure and the upper surface of the rock wool is a plane, when the mounting part moves downward and fits with the upper surface of the rock wool, the smooth curved surface at the lower end of the rotating part squeezes the rock wool, causing a semicircular pit to form in the rock wool. At this time, the rock wool membrane at the semicircular pit fits the rock wool more tightly, and when the rotating part rotates clockwise, the claw hook can easily be inserted into the rock wool membrane.

[0014] The advantage of this solution is that since there is a certain amount of air between the rock wool film and the rock wool, they are not completely fitted together, and the claw hook portion of the present application, due to its specific structure, does not embed deeply enough into the rock wool; therefore, a semicircular pit is squeezed and produced on the rock wool, which facilitates the close fit between the rock wool film and the rock wool, thereby ensuring that the success rate of the claw hook portion of the present application in grabbing the rock wool film reaches 100%.

[0015] Preferably, the distance between the rotating part and the claw hook part is 0.5 cm to 2 cm. The technical effect of this solution is that the distance between the rotating part and the claw hook part is relatively small, which is used to avoid damage to the rock wool.

[0016] Furthermore, the claw hook portion has a tip and a mounting end, the tip is used to puncture the film, and the mounting end is fixed on the mounting arm.

[0017] Furthermore, the claw hook portion and the mounting arm are integrally formed.

[0018] Furthermore, the mounting portion is a flat plate component, and the mounting portion is horizontally arranged, and the axis of the rotating portion is parallel to the mounting portion.

[0019] The second problem solved by this application is how to separate the rock wool membrane from the claw hook part. The basis for solving this problem is that the axis of the rotating part and the claw hook part coincide. On the basis of the above, the structure of the mounting plate is further improved as follows:

[0020] The mounting portion is provided with a knife-back opening, which is connected to the opening groove, and is used to provide a rotation channel for the claw hook portion and to separate the claw hook portion from the film. When the rotating portion rotates counterclockwise, the claw hook portion returns to the initial position; when the claw hook portion passes through the knife-back opening, the lower surface of the mounting portion blocks the rock wool film, and the rock wool film is automatically separated at this time.

[0021] The exception is that even if the knife-back is set in the prior art, it cannot solve this problem, or cannot separate the rock wool film well. The reason is that the L-shaped gripper or other shapes of grippers in the prior art are not coaxially arranged with the rotating part, which easily causes the gripper and the rock wool film to be clamped too tightly. If the knife-back is forcibly set, it is easy for the film to be entangled or stuck in the knife-back, which can easily cause damage to the device.

[0022] Preferably, the driving part is a gear rack mechanism or a servo motor. There are many existing technologies for realizing the rotation of the rotating part, such as a cylinder driving a rack to move linearly, and the rack driving a gear on the rotating part to rotate; the rotating shaft of the servo motor and the rotating part are coaxially fixed; or the output shaft of the rotary cylinder and the rotating part are coaxially fixed, etc., which will not be exhaustively listed here.

[0023] Preferably, two hook needles are provided on the same rotating part, and the two hook needles are respectively located at two ends of the axial direction of the rotating part.

[0024] The technical effect of this solution is to improve the grabbing efficiency of the hook on the rock wool film.

[0025] In addition, the present application also proposes a packaging film removal device, including the above-mentioned film hooking mechanism. The packaging film removal device adopts the film hooking mechanism of the present application, which can better realize the grasping of the packaging film and the fixed-point separation, thereby realizing the automatic peeling of the packaging film.

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] like Figures 1 to 8 As shown, this embodiment proposes a film hooking mechanism, including:

[0039] A mounting portion 11, wherein the mounting portion 11 is provided with an opening slot 12;

[0040] The rotating portion 13 is cylindrical and rotatably disposed in the opening slot 12;

[0041] The hook needle 14 includes a mounting arm 15 and a claw hook portion 16. The claw hook portion 16 is fixed to the rotating portion 13 through the mounting arm 15. The claw hook portion 16 is arc-shaped. The axes of the rotating portion 13 and the claw hook portion 16 coincide. A gap 17 is left between the side of the claw hook portion 16 facing the rotating portion 13 and the rotating portion 13. The gap 17 is as shown in FIG. Figure 6 As shown;

[0042] The driving part 18 is used to drive the rotating part 13 to rotate.

[0043] The idea of ​​this solution is to propose a technical solution that can effectively grab the rock wool film and reduce the damage to the rock wool. Among them, the application designs the shape of the hook 14, and the arc-shaped claw hook part 16 of the hook 14 is coaxially arranged with the rotating part 13, so that the gap 17 between the claw hook part 16 and the rotating part 13 is always equal. When the claw hook part 16 grabs the rock wool film, as the rotating part 13 rotates clockwise, the rock wool film will extend into the gap 17 along the arc direction of the gap 17, which is conducive to grabbing the rock wool film, and the rock wool film is not easy to fall off.

[0044] In addition, compared with the grab hook in the prior art CN202022539250.6, the technical solution of the present application has the advantages of less damage to the rock wool, simple structure, and not easy to fall off. It has been explained above that the rock wool film will extend into the gap 17 along the arc direction of the gap 17, so a part of the rock wool film is stuck in the gap 17 and is difficult to fall off.

[0045] An arc groove 23 is provided on the circumference of the rotating part 13 , and the arc groove 23 and the claw hook part 16 are arranged opposite to each other. The arc groove 23 can accommodate the rock wool film on the claw hook part 16 to a certain extent, so as to facilitate the movement of the rock wool film between the rotating part 13 and the claw hook part 16 .

[0046] Furthermore, the claw hook portion 16 is 1 / 4 to 1 / 2 circular. The claw hook portion 16 can also be set to be 3 / 8 to 7 / 8 circular. The rock wool film can be effectively grasped, and the grasping efficiency of the claw hook portion 16 is guaranteed.

[0047] Furthermore, the shortest distance between the outer circumference of the claw hook portion 16 and the outer circumference of the rotating portion 13 is 2.5 cm to 6 cm, so as to reduce the damage caused by the claw hook portion 16 to the rock wool.

[0048] As an implementation method of this embodiment, Figure 4 As shown, the top end of the rotating part 13 along the vertical direction is located above the mounting part 11, and the bottom end of the rotating part 13 along the vertical direction is located below the mounting part 11, and the distance d2 between the top end of the rotating part 13 and the upper surface of the mounting part 11 is equal to the distance d3 between the bottom end of the mounting part 11 and the lower surface of the mounting part 11.

[0049] In the initial state, the claw hook portion 16 is located at the upper end of the peripheral surface of the rotating portion 13, and the lower end of the peripheral surface of the rotating portion 13 is a smooth curved surface. Figure 7 and Figure 8 As shown, since the rock wool is a block structure and the upper surface of the rock wool is a plane, when the mounting portion 11 moves downward and fits with the upper surface of the rock wool, the smooth curved surface at the lower end of the rotating portion 13 is squeezed with the rock wool, so that a semicircular pit 22 is produced in the rock wool. At this time, the rock wool film at the semicircular pit 22 fits closely with the rock wool. When the rotating portion 13 rotates clockwise, the claw hook portion 16 can be easily inserted into the rock wool film.

[0050] The advantage of this solution is that since there is a certain amount of air between the rock wool film and the rock wool, they are not completely fitted together, and the claw hook portion 16 of the present application has a specific structure, so that the claw hook portion 16 is not embedded deeply enough in the rock wool; therefore, a semicircular pit 22 is squeezed and produced on the rock wool, which facilitates the close fit between the rock wool film and the rock wool, thereby ensuring that the success rate of the claw hook portion 16 of the present application in grabbing the rock wool film reaches 100%.

[0051] As an implementation of this embodiment, the distance d1 between the rotating part 13 and the claw hook part 16 is 0.5 cm to 2 cm. The technical effect of this solution is that the distance between the rotating part 13 and the claw hook part 16 is relatively small, which is used to avoid damage to the rock wool.

[0052] Furthermore, the claw hook portion 16 has a tip and a mounting end, the tip is used to puncture the film, and the mounting end is fixed on the mounting arm 15 .

[0053] Furthermore, the claw hook portion 16 and the mounting arm 15 are integrally formed.

[0054] Furthermore, the mounting portion 11 is a flat plate member, and the mounting portion 11 is horizontally arranged, and the axis of the rotating portion 13 is parallel to the mounting portion 11 .

[0055] The second problem solved by the present application is how to separate the rock wool membrane from the claw hook portion 16. The basis for solving this problem is that the axis of the rotating portion 13 and the claw hook portion 16 coincide. On the basis of the above, the structure of the mounting plate is further improved as follows:

[0056] like Figure 1 and Figure 2 As shown, the mounting portion 11 is provided with a knife-back opening 19, which is connected to the opening slot 12, and is used to provide a rotation channel for the claw hook portion 16 and to separate the claw hook portion 16 from the film. When the rotating portion 13 rotates counterclockwise, the claw hook portion 16 returns to the initial position; when the claw hook portion 16 passes through the knife-back opening 19, the lower surface of the mounting portion 11 blocks the rock wool film, and the rock wool film is automatically separated at this time.

[0057] The exception is that even if the knife-back 19 is set in the prior art, this problem cannot be solved, or the rock wool film cannot be separated well. The reason is that the L-shaped gripper or other shapes of grippers in the prior art are not coaxially arranged with the rotating part 13, which easily causes the gripper and the rock wool film to be clamped too tightly. If the knife-back 19 is forcibly set, it is easy for the film to be entangled or stuck in the knife-back 19, which easily causes damage to the device.

[0058] As an implementation of this embodiment, the driving part 18 is a gear rack mechanism or a servo motor. There are many existing technologies for realizing the rotation of the rotating part 13, such as a cylinder driving a rack to move linearly, and the rack driving a gear on the rotating part 13 to rotate; the rotating shaft of the servo motor and the rotating part 13 are coaxially fixed; or the output shaft of the rotary cylinder and the rotating part 13 are coaxially fixed, etc., which will not be exhaustively listed here.

[0059] As an implementation of this embodiment, two hook needles 14 are provided on the same rotating part 13 , and the two hook needles 14 are respectively located at two ends of the axial direction of the rotating part 13 .

[0060] The technical effect of this solution is to improve the grabbing efficiency of the hook needle 14 on the rock wool film.

[0061] Working principle: After the rock wool and the rock wool film are cut, they are transported to the designated work station together; the telescopic part 21 on the support plate 20 extends downward and drives the mounting part 11 to fit the upper surface of the rock wool. At this time, the smooth curved surface at the lower end of the rotating part 13 is squeezed with the rock wool, causing a semicircular pit 22 to form in the rock wool. Then the driving part 18 works and drives the hook 14 on the rotating part 13 to move clockwise, and a part of the rock wool film is stuck in the gap 17 between the claw hook part 16 and the rotating part 13.

[0062] Then the telescopic member 21 contracts, driving the claw hook portion 16, the rotating portion 13 and the mounting portion 11 to move upward together, thereby achieving the separation of the film on the rock wool.

[0063] A return spring is disposed on the outer periphery of the telescopic member 21 . When the power source of the telescopic member 21 is removed, the return spring returns to its original state, thereby restoring the distance between the mounting portion 11 and the support plate 20 to an initial state.

[0064] When the film hooking mechanism is moved to the specified position, the driving part 18 drives the rotating part 13 to rotate counterclockwise. When the claw hook part 16 passes through the retreating edge 19, the lower surface of the mounting part 11 blocks the rock wool film, thereby achieving the separation of the film and the claw hook part 16.

[0065] In addition, the present application also proposes a packaging film removal device, including the above-mentioned film hooking mechanism. The packaging film removal device adopts the film hooking mechanism of the present application, which can better realize the grasping of the packaging film and the fixed-point separation, thereby realizing the automatic peeling of the packaging film.

[0066] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, all of which fall within the protection scope of the present invention.
