Description

Technical Field

[0001] This invention belongs to the field of processing equipment maintenance, and specifically relates to a device for removing rubber strips from swing arms. Background Technology

[0002] Vibrating troughs, also known as vibrating conveyors, are one of the important auxiliary equipment in cigarette manufacturing production lines. This equipment uses centrifugal inertial force to loosen and transport materials, and is widely used in the conveying of tobacco materials such as tobacco shreds and tobacco leaves in cigarette manufacturing lines.

[0003] The swing arm is a crucial component for transmitting power between the vibratory trough and the frame. It primarily consists of an arm body 11, a mounting base 12, and a rubber strip 13. The arm body 11 has mounting frames 110 at both ends, and a rectangular post 120 is mounted on the mounting base 12. The mounting frames 110 are fitted onto the rectangular posts 120, with their diagonals forming a 45° angle, thus creating a triangular space at the corner of the mounting frame 110. The rubber strip 13 is then secured within this triangular space. The rubber strip is the core of this component; through its vibration damping and absorption properties, the swing arm assembly provides a buffering effect.

[0004] During the vibration of the swing arm, the mounting frame 110 and the rectangular column 120 will compress and rub against the rubber strip 13, so the rubber strip 13 will be deformed under force, and the friction will cause wear on the rubber, resulting in the swing arm falling off and being damaged.

[0005] Traditionally, the maintenance method for replacing the entire swing arm after the rubber strip wears out has resulted in significant cost expenditures.

[0006] If the rubber strips can be replaced directly, maintenance costs will be greatly reduced.

[0007] Among these issues, the rapid removal of the rubber strip from the swing arm is the primary concern at this stage. Summary of the Invention

[0008] The purpose of this invention is to provide a device for removing rubber strips from a swing arm. After positioning the device and the mounting frame through a positioning frame and a limiting frame, the rotating sleeve is screwed to the positioning rod. When the motor drives the rotating sleeve to rotate via gears, the rotating sleeve moves downward and rotates, thereby driving the spiral hook to screw into the rubber strip. Then, the device is pulled outward to quickly remove the rubber strip from the swing arm. This invention is convenient to use.

[0009] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0010] A device for removing rubber strips from a swing arm, comprising:

[0011] A positioning frame for positioning the mounting frame, the positioning frame having a hollow structure, a notch on one side of the positioning frame, and a limiting frame on the upper part of the inner wall of the positioning frame;

[0012] Mounting bracket, which is fixedly mounted on the positioning frame;

[0013] Four positioning rods are installed on the mounting bracket and correspond to the position of the rubber strip. The positioning rods are provided with external threads.

[0014] A rotating sleeve is screwed onto the positioning rod, and a helical hook is fixedly installed at the lower end of the rotating sleeve. The direction of rotation of the helical hook is the same as the direction of rotation of the external thread on the positioning rod.

[0015] A motor is fixedly mounted on the mounting bracket, and a gear is driven on the power output shaft of the motor, the gear meshing with a rotating sleeve.

[0016] Furthermore, the motor is a reversible motor.

[0017] This structural design allows for rapid reset of the rotating sleeve by rotating the motor in both directions. Additionally, after removing the rubber strip from the swing arm, the motor can be rotated in reverse while holding the rubber strip, making the spiral hook easier to use.

[0018] Furthermore, the inner wall of the limiting frame is fixedly provided with a sub-seat at the position corresponding to the positioning rod, and a puncture needle for puncturing the adhesive strip is installed on the sub-seat.

[0019] This structural design uses a puncture needle to puncture the adhesive strip. The motor, which acts as a forward and reverse motor, drives the spiral hook to rotate in the opposite direction. As the spiral hook unscrews the adhesive strip, the puncture needle secures the adhesive strip to the positioning frame, eliminating the need to hold the adhesive strip by hand and making it more convenient to use.

[0020] Further specified, the sub-seat has a through hole, and the puncture needle has a truncated cone fixed in the middle, the truncated cone being located inside the through hole;

[0021] The through hole is provided with limiting rings at both the top and bottom of the frustum;

[0022] When the puncture needle rests against the rubber strip, the upper end of the puncture needle is above the upper surface of the sub-seat.

[0023] When the rotating sleeve rests against the upper surface of the sub-seat, the lower end of the puncture needle is inserted into the rubber strip.

[0024] This structural design, through the sliding setting of the puncture needle, uses the downward movement of the rotating sleeve to push the puncture needle into the rubber strip, eliminating the need for manual puncture, making it more convenient to use and highly practical.

[0025] Furthermore, the positioning rod is axially slidably mounted on the mounting bracket;

[0026] When the positioning rod moves upward relative to the limiting frame to the upper position, the rotating sleeve corresponding to the positioning rod disengages from the gear;

[0027] When the positioning rod moves downward relative to the limiting frame to the lower position, the rotating sleeve corresponding to the positioning rod meshes with the gear;

[0028] A fixing mechanism is installed between the positioning rod and the mounting bracket.

[0029] This structural design, by differentiating the positioning rod between the upward and downward positions, ensures that the gears only mesh with the corresponding gears, thereby driving only the corresponding spiral hooks to rotate and move, and thus only removing the corresponding rubber strips. In cases where not all rubber strips in the same mounting frame need to be replaced, the removal of the corresponding rubber strips can be completed selectively, making it more convenient to use and more practical.

[0030] Further specifying, the fixing mechanism is a fixing bolt that is horizontally screwed onto the mounting bracket;

[0031] The inner end of the fixing bolt rests against the positioning rod.

[0032] This structural design uses fixing bolts as a fixing mechanism to fix the positioning rod to the mounting bracket. It has a simple structure, low cost, and strong practicality.

[0033] Further specifying, the fixing mechanism is a transverse clamp rod that extends laterally through the mounting frame;

[0034] The outer end of the transverse clamp is located outside the mounting frame, and an elastic mechanism for driving the transverse clamp to move in the direction of the positioning rod is installed between the transverse clamp and the mounting frame.

[0035] The positioning rod has two positioning holes, which are located at different heights on the positioning rod.

[0036] When the transverse locking rod is inserted into the positioning hole located at the top, the positioning rod is in the upward position;

[0037] When the transverse locking rod is inserted into the positioning hole located at the bottom, the positioning rod is in the downward position.

[0038] This structural design uses a horizontal clamp as a fixing mechanism, along with an elastic mechanism and positioning holes, to fix the positioning rod to the mounting bracket. It is simple to operate and easy to use.

[0039] Furthermore, the mounting bracket has a through hole at the position corresponding to the positioning rod, and the positioning rod passes through the through hole;

[0040] A pull ring is fixedly provided at the upper end of the positioning rod;

[0041] The upper end face of the mounting bracket is provided with a first groove and a second groove at the position corresponding to the through hole, and the depth of the first groove is smaller than the depth of the second groove.

[0042] When the pull ring is located in the first groove, the rotating sleeve corresponding to the positioning rod disengages from the gear;

[0043] When the pull ring is located in the second groove, the rotating sleeve corresponding to the positioning rod meshes with the gear.

[0044] This structural design, through the cooperation of the pull ring with the first and second grooves, allows the pull ring to be placed in different grooves, so that the gear only meshes with the corresponding gear, thereby driving only the corresponding spiral hook to rotate and move, and thus only removing the corresponding rubber strip. In cases where not all rubber strips in the same mounting frame need to be replaced, the corresponding rubber strip can be removed selectively, making it more convenient to use and more practical.

[0045] Further specified, a first retaining ring is fixedly provided inside the through hole, and a second retaining ring is fixedly installed on the positioning rod;

[0046] A compression spring is fitted between the first retaining ring and the second retaining ring on the positioning rod.

[0047] This structural design, through the cooperation of the compression spring and the first and second retaining rings, creates a downward push on the positioning rod. This allows the pull ring to be more easily engaged in the first and second grooves, and also utilizes the elasticity of the compression spring to temporarily fix the positioning rod, making it more convenient to use.

[0048] Furthermore, a handle is fixedly installed at the upper end of the mounting bracket.

[0049] This structural design, with the addition of a handle, allows the removal device to be pulled after the spiral hook is screwed into the rubber strip, thereby causing the rubber strip to detach from the swing arm. This makes it more convenient to use and more practical.

[0050] The invention employing the above technical solution has the following advantages:

[0051] 1. After positioning the removal device and the mounting frame through the positioning frame and the limiting frame, the rotating sleeve and the positioning rod are screwed together. When the motor drives the rotating sleeve to rotate through the gear, the rotating sleeve moves downward and rotates, which in turn drives the spiral hook to screw into the rubber strip. Then, the removal device is pulled outward to quickly remove the rubber strip in the swing arm. It is convenient to use.

[0052] 2. By rotating the motor in both directions, the rotating sleeve can be quickly reset. At the same time, after removing the rubber strip from the swing arm, the motor can be rotated in reverse while holding the rubber strip, making the spiral hook unscrew the rubber strip, which is more convenient to use.

[0053] 3. The adhesive strip is punctured by a puncture needle. The motor, which acts as a forward and reverse motor, drives the spiral hook to rotate in the opposite direction. As the spiral hook unscrews the adhesive strip, the puncture needle fixes the adhesive strip to the positioning frame. There is no need to hold the adhesive strip by hand, making it more convenient to use.

[0054] 4. By sliding the puncture needle and using the downward movement of the rotating sleeve, the puncture needle is pushed into the rubber strip, eliminating the need for manual puncture, making it more convenient and practical.

[0055] 5. By differentiating between the upward and downward positions of the positioning rod, the gears only mesh with the corresponding gears, thereby driving only the corresponding spiral hooks to rotate and move, and thus only removing the corresponding rubber strips. In cases where not all rubber strips in the same mounting frame need to be replaced, the corresponding rubber strips can be removed selectively, making it more convenient to use and more practical.

[0056] 6. By engaging the pull ring with the first and second grooves, the pull ring is placed in different grooves, allowing the gear to mesh with only the corresponding gear. This drives only the corresponding spiral hook to rotate and move, thus removing only the corresponding rubber strip. In cases where not all rubber strips in the same mounting frame need to be replaced, the corresponding rubber strip can be removed selectively, making it more convenient and practical.

[0073] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0074] like Figures 2-8 As shown, a swing arm adhesive strip removal device of the present invention includes:

[0075] The positioning frame 2 is used to position the mounting frame 110. The positioning frame 2 has a hollow structure, a notch on one side, and a limiting frame 21 on the upper part of the inner wall of the positioning frame 2.

[0076] Mounting bracket 3 is fixedly installed on positioning frame 2;

[0077] Four positioning rods 4 are installed on the mounting bracket 3 and correspond to the position of the rubber strip 13. The positioning rods 4 are provided with external threads.

[0078] A rotating sleeve 5 is screwed onto the positioning rod 4. A spiral hook 50 is fixedly installed at the lower end of the rotating sleeve 5. The spiral hook 50 has the same direction of rotation as the external thread on the positioning rod 4.

[0079] The motor 6 is fixedly mounted on the mounting bracket 3. A gear 60 is installed on the power output shaft of the motor 6, and the gear 60 meshes with the rotating sleeve 5.

[0080] Motor 6 is a forward and reverse rotating motor.

[0081] In practice, depending on the actual situation, a unidirectional rotating motor 6 can be selected. During reset, the rotating sleeve 5 can be reset manually. In this embodiment, the rotating sleeve 5 can be quickly reset by rotating the motor 6 in both directions. At the same time, after removing the rubber strip 13 from the swing arm, the spiral hook 50 can be unscrewed by rotating the motor 6 while holding the rubber strip 13, making it more convenient to use.

[0082] like Figure 6 and Figure 7 As shown, the inner wall of the limiting frame 21 is fixedly provided with a sub-seat 22 at the corresponding position of the positioning rod 4, and a puncture needle 23 for puncturing the adhesive strip 13 is installed on the sub-seat 22.

[0083] With this structural design, the adhesive strip 13 is punctured by the puncture needle 23. The spiral hook 50 is rotated in the opposite direction by the motor 6, which acts as a forward and reverse motor. When the spiral hook 50 unscrews the adhesive strip 13, the puncture needle 23 is used to fix the adhesive strip 13 to the positioning frame 2. There is no need to hold the adhesive strip 13 by hand, making it more convenient to use.

[0084] like Figure 6 and Figure 7 As shown, a through hole 220 is provided on the sub-base 22, and a frustum 230 is fixedly provided in the middle of the puncture needle 23, with the frustum 230 located inside the through hole 220.

[0085] Limiting rings 221 are provided above and below the frustum 230 in the through hole 220;

[0086] When the puncture needle 23 rests against the adhesive strip 13, the upper end of the puncture needle 23 is above the upper end face of the sub-seat 22.

[0087] When the rotating sleeve 5 rests against the upper surface of the sub-seat 22, the lower end of the puncture needle 23 is inserted into the rubber strip 13.

[0088] In practice, depending on the actual situation, one can also choose to directly fix the puncture needle 23 on the sub-base 22 so as to directly push the removal device to move towards the adhesive strip 13 and insert the puncture needle 23 into the adhesive strip 13. In this embodiment, by sliding the puncture needle 23, the downward movement of the rotating sleeve 5 is used to push the puncture needle 23 into the adhesive strip 13, eliminating the need for manual puncture, making it more convenient to use and more practical.

[0089] The positioning rod 4 is axially slidably mounted on the mounting bracket 3. This axial sliding mounting can be achieved by either opening a positioning groove axially on the positioning rod 4 and setting a corresponding limit strip on the mounting bracket 3, or by setting the upper end of the positioning rod 4 as a prism and opening a corresponding diamond-shaped hole on the mounting bracket 3.

[0090] When the positioning rod 4 moves upward relative to the limit frame 21 to the upper position, the rotating sleeve 5 corresponding to the positioning rod 4 disengages from the gear 60.

[0091] When the positioning rod 4 moves downward relative to the limit frame 21 to the lower position, the rotating sleeve 5 corresponding to the positioning rod 4 meshes with the gear 60.

[0092] A fixing mechanism is installed between the positioning rod 4 and the mounting bracket 3.

[0093] In practice, depending on the actual situation, the positioning rod 4 can be directly fixed on the mounting bracket 3. Each time it is removed, all the rubber strips 13 in the same mounting frame 110 are removed. In this embodiment, by distinguishing between the upward and downward positions of the positioning rod 4, the gear 60 only meshes with the corresponding gear 60, thereby only driving the corresponding spiral hook 50 to rotate and move, and thus only removing the corresponding rubber strip 13. In the case that not all the rubber strips 13 in the same mounting frame 110 are replaced, the corresponding rubber strips 13 can be removed in a targeted manner, which is more convenient to use and has strong practicality.

[0094] The fixing mechanism is a fixing bolt that is horizontally screwed onto the mounting bracket 3;

[0095] The inner end of the fixing bolt rests against the positioning rod 4.

[0096] The positioning rod 4 and the mounting bracket 3 are fixed by fixing bolts. The structure is simple, the cost is low and the practicality is strong.

[0097] The fixing mechanism is a horizontal clamp rod that passes through the mounting frame 3 laterally;

[0098] The outer end of the transverse locking rod is located outside the mounting bracket 3, and an elastic mechanism for driving the transverse locking rod to move in the direction of the positioning rod is installed between the transverse locking rod and the mounting bracket 3.

[0099] The positioning rod 4 has two positioning holes, which are located at different heights on the positioning rod 4.

[0100] When the transverse locking rod is inserted into the positioning hole located at the top, the positioning rod 4 is in the upward position;

[0101] When the transverse locking rod is inserted into the positioning hole located at the bottom, the positioning rod 4 is in the downward position.

[0102] The horizontal clamping rod serves as a fixing mechanism, which, together with the elastic mechanism and positioning holes, completes the fixing between the positioning rod 4 and the mounting bracket 3. The operation is simple and convenient.

[0103] The mounting bracket 3 has a through hole 30 at the corresponding position of the positioning rod 4, and the positioning rod 4 passes through the through hole 30;

[0104] A pull ring 40 is fixedly provided at the upper end of the positioning rod 4;

[0105] The upper end face of the mounting bracket 3 is provided with a first groove 31 and a second groove 32 at the position corresponding to the through hole 30. The depth of the first groove 31 is smaller than the depth of the second groove 32.

[0106] When the pull ring 40 is located in the first groove 31, the rotating sleeve 5 corresponding to the positioning rod 4 disengages from the gear 60.

[0107] When the pull ring 40 is located in the second groove 32, the rotating sleeve 5 corresponding to the positioning rod 4 meshes with the gear 60.

[0108] By engaging the pull ring 40 with the first groove 31 and the second groove 32, the pull ring 40 is placed in different grooves, so that the gear 60 only meshes with the corresponding gear 60, thereby driving only the corresponding spiral hook 50 to rotate and move, and thus only removing the corresponding rubber strip 13. In the case that not all rubber strips 13 in the same mounting frame 110 are replaced, the corresponding rubber strip 13 can be removed in a targeted manner, which is more convenient to use and has strong practicality.

[0109] A first retaining ring 41 is fixedly installed inside the through hole 30, and a second retaining ring 42 is fixedly installed on the positioning rod 4;

[0110] A compression spring 43 is fitted between the first retaining ring 41 and the second retaining ring 42 on the positioning rod 4.

[0111] The compression spring 43, in cooperation with the first retaining ring 41 and the second retaining ring 42, pushes the positioning rod 4 downward, which makes it easier for the pull ring 40 to be inserted into the first groove 31 and the second groove 32. The elastic force of the compression spring 43 can also be used to temporarily fix the positioning rod 4, making it more convenient to use.

[0112] A handle 33 is also fixedly installed on the upper end of the mounting bracket 3.

[0113] By setting the handle 33, after the spiral hook 50 is screwed into the rubber strip 13, the removal device can be pulled by the handle 33, thereby driving the rubber strip 13 to disengage from the swing arm, making it more convenient to use and more practical.

[0114] In this embodiment, when in use, the positioning rod 4 corresponding to the adhesive strip 13 to be removed is pushed to the downward position according to the position of the adhesive strip 13 to be removed, that is, the pull ring 40 on the corresponding positioning rod 4 is pushed into the corresponding second groove 32, so that the corresponding rotating sleeve 5 meshes with the gear 60;

[0115] Next, attach the positioning frame 2 to the corresponding mounting frame 110, ensuring that the limiting bracket 21 rests against the side of the mounting frame 110 away from the mounting base 12. Figure 2 and Figure 3 ;

[0116] Start the motor 6, which drives the rotating sleeve 5 to rotate counterclockwise via the gear 60, thereby driving the spiral hook 50 to screw into the rubber strip 13 until the rotating sleeve 5 rests against the upper end of the puncture needle 23.

[0117] The rotating sleeve 5 continues to move, causing the puncture needle 23 to insert into the corresponding adhesive strip 13, such as... Figure 4 , Figure 5 and Figure 7 As shown;

[0118] Grasp handle 33 to move the removal device away from the swing arm, thereby disengaging the corresponding rubber strip 13 from the swing arm. Figure 8 As shown;

[0119] Control the motor 6 to rotate in the opposite direction, which in turn drives the rotating sleeve 5 to rotate in the opposite direction (clockwise) via the gear 60. This, in conjunction with the fixation of the adhesive strip 13 by the puncture needle 23, causes the spiral hook 50 to unscrew from the adhesive strip 13. Finally, the adhesive strip 13 can be pulled off the puncture needle 23.

[0120] The above provides a detailed description of the swing arm rubber strip removal device provided by the present invention. The specific embodiments are described only to help understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
