Description

Technical Field

[0001] The invention belongs to the field of processing equipment maintenance, and in particular relates to a swing arm rubber strip removal device. Background Art

[0002] The vibration trough, also known as the vibrating conveyor, is one of the important auxiliary equipment in the tobacco production line of a cigarette factory. The equipment uses centrifugal inertia to loosen and convey materials. It is widely used in the conveying of tobacco materials such as tobacco shreds and tobacco leaves in the tobacco production line.

[0003] The swing arm is an important component for transmitting power between the vibration trough body and the frame, and is mainly composed of an arm body 11, a mounting seat 12 and a rubber strip 13. Both ends of the arm body 11 are provided with a mounting frame 110, and a rectangular square column 120 is provided on the mounting seat 12. The mounting frame 110 is sleeved on the rectangular square column 120, and the diagonal lines of the two are set at an angle of 45°, so that a triangular space is enclosed at the corner position of the mounting frame 110, and the rubber strip 13 is stuck in this triangular space. The rubber strip is the core of the component. Through the vibration reduction and vibration absorption of the rubber strip, the swing arm component plays a buffering role.

[0004] As the swing arm vibrates, the mounting frame 110 and the rectangular column 120 squeeze and rub the rubber strip 13 , so the rubber strip 13 is deformed by force, and the friction causes the rubber to wear, thereby causing the swing arm to fall off and be damaged.

[0005] Until now, the maintenance mode adopted is to replace the whole swing arm after the rubber strip is worn, which results in huge cost consumption.

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

[0007] Among them, the rapid removal of the rubber strip in the swing arm is the primary issue to be considered at this stage. Summary of the invention

[0008] The purpose of the present invention is to provide a swing arm rubber strip removal device. After the removal device and the installation frame are positioned by a positioning frame and a limit 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, thereby driving the spiral hook to screw into the rubber strip. The removal device is then pulled outward, so that the rubber strip in the swing arm can be quickly removed. The invention is easy to use.

[0009] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows: A swing arm rubber strip removal device, comprising: A positioning frame for positioning the installation frame, the positioning frame being a hollow structure, a notch being provided on one side of the positioning frame, and a limit frame being provided on the upper part of the inner wall of the positioning frame; A mounting frame, the mounting frame being fixedly mounted on the positioning frame; Four positioning rods, all of which are mounted on the mounting frame and correspond to the positions of the rubber strips, and each positioning rod is provided with an external thread; A rotating sleeve is screwed onto the positioning rod, a spiral hook is fixedly mounted on the lower end of the rotating sleeve, and the spiral hook has the same rotation direction as the external thread on the positioning rod; A motor is fixedly mounted on the mounting frame, and a gear is transmission-mounted on a power output shaft of the motor, and the gear is meshed with a rotating sleeve.

[0010] It is further defined that the motor is a forward and reverse motor.

[0011] Such a structural design can realize the rapid resetting of the rotating sleeve through the forward and reverse rotation of the motor. At the same time, after the rubber strip is pulled out from the swing arm, the spiral hook can be unscrewed out of the rubber strip by using the reverse rotation of the motor while holding the rubber strip, which is more convenient to use.

[0012] It is further defined that a sub-seat is fixedly provided on the inner wall of the limiting frame at a position corresponding to the positioning rod, and a puncture needle for puncturing the adhesive strip is installed on the sub-seat.

[0013] This structural design punctures the rubber strip with a puncture needle, and when the motor serving as a forward and reverse motor drives the spiral hook to rotate in the opposite direction, the spiral hook is screwed out of the rubber strip. The puncture needle is used to fix the rubber strip to the positioning frame, and there is no need to hold the rubber strip by hand, making it more convenient to use.

[0014] It is further defined that a through hole is formed on the auxiliary seat, a round table is fixedly provided at the middle of the puncture needle, and the round table is located in the through hole; The through hole is provided with limiting rings above and below the truncated cone; When the puncture needle is against the rubber strip, the upper end of the puncture needle is located above the upper end surface of the auxiliary seat; When the rotating sleeve is pressed against the upper end surface of the auxiliary seat, the lower end of the puncture needle is inserted into the rubber strip.

[0015] Such a structural design, through the sliding setting of the puncture needle, utilizes the downward movement of the rotating sleeve to push the puncture needle into the rubber strip, without the need for manual puncture, is more convenient to use and has strong practicality.

[0016] It is further defined that the positioning rod is axially slidably mounted on the mounting frame; When the positioning rod moves upward to the upward position relative to the limiting frame, the rotating sleeve corresponding to the positioning rod is disengaged from the gear; When the positioning rod moves downward to the lower position relative to the limiting frame, the rotating sleeve corresponding to the positioning rod meshes with the gear; A fixing mechanism is installed between the positioning rod and the mounting frame.

[0017] This structural design, through the difference between the positioning rod being in the upward position and the downward position, allows the gear to mesh only with the corresponding gear, thereby only driving the corresponding spiral hook to rotate and move, and then only completing the removal of the corresponding rubber strip. In the case of not replacing all the rubber strips in the same installation frame, the corresponding rubber strip can be removed in a targeted manner, which is more convenient to use and has strong practicality.

[0018] It is further defined that the fixing mechanism is a fixing bolt that is transversely screwed onto the mounting frame; The inner end of the fixing bolt rests on the positioning rod.

[0019] Such a structural design uses fixing bolts as a fixing mechanism to complete the fixation between the positioning rod and the mounting frame, and has a simple structure, low cost and strong practicality.

[0020] It is further defined that the fixing mechanism is a transverse clamping rod transversely provided on the mounting frame; The outer end of the transverse clamping rod is located outside the mounting frame, and an elastic mechanism for driving the transverse clamping rod to move in the direction of the positioning rod is installed between the transverse clamping rod and the mounting frame; The positioning rod is provided with two positioning holes, and the positioning holes are located at different height levels of the positioning rod; When the transverse clamping rod is inserted into the positioning hole at the upper part, the positioning rod is located at the upward position; When the transverse clamping rod is inserted into the positioning hole at the lower part, the positioning rod is located at the downward position.

[0021] Such a structural design uses the transverse clamping rod as a fixing mechanism, cooperates with the elastic mechanism and the positioning hole to complete the fixation between the positioning rod and the mounting frame, and is simple to operate and easy to use.

[0022] It is further defined that the mounting frame is provided with a through hole at a position corresponding to the positioning rod, and the positioning rod is inserted into the through hole; A pull ring is fixedly provided on the upper end of the positioning rod; The upper end surface of the mounting frame is provided with a first groove and a second groove at positions corresponding to the through holes, and the depth dimension of the first groove is smaller than the depth dimension of the second groove; When the pull ring is located in the first groove, the rotating sleeve corresponding to the positioning rod is disengaged from the gear; When the pull ring is located in the second groove, the rotating sleeve corresponding to the positioning rod is meshed with the gear.

[0023] Such a structural design, through the cooperation of the pull ring with the first groove and the second groove, by placing the pull ring in different grooves, makes the gear only mesh with the corresponding gear, thereby only driving the corresponding spiral hook to rotate and move, and then only completing the removal of the corresponding rubber strip. In the case of not replacing all the rubber strips in the same installation frame, the corresponding rubber strip can be removed in a targeted manner, which is more convenient to use and has strong practicality.

[0024] It is further defined that a first retaining ring is fixedly provided in the through hole, and a second retaining ring is fixedly installed on the positioning rod; The positioning rod is sleeved with a compression spring between the first retaining ring and the second retaining ring.

[0025] Such a structural design, through the cooperation between the compression spring and the first retaining ring and the second retaining ring, forms a downward push on the positioning rod, which can make the pull ring more easily fit into the first groove and the second groove, and can also use the elastic force of the compression spring to temporarily fix the positioning rod, making it more convenient to use.

[0026] It is further defined that a handle is fixedly mounted on the upper end of the mounting frame.

[0027] Such a structural design, through the setting of the handle, allows the spiral hook to be screwed into the rubber strip, and the removal device can be pulled through the handle, thereby driving the rubber strip to detach from the swing arm, which is more convenient to use and more practical.

[0028] The invention adopting the above technical solution has the following advantages: 1. After the removal device and the installation frame are positioned by 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, thereby driving the spiral hook to screw into the rubber strip. Then the removal device is pulled outward, and the rubber strip in the swing arm can be quickly removed. It is easy to use. 2. The rotating sleeve can be quickly reset by rotating the motor forward and reversely. At the same time, after the rubber strip is pulled out from the swing arm, the spiral hook can be rotated out of the rubber strip by rotating the motor reversely while holding the rubber strip, which is more convenient to use. 3. Puncture the rubber strip with the puncture needle, and when the motor as the forward and reverse motor drives the spiral hook to rotate in the opposite direction, the spiral hook is screwed out of the rubber strip, and the puncture needle is used to fix the rubber strip and the positioning frame, so that the rubber strip does not need to be held by hand, which is more convenient to use; 4. Through the sliding setting of the puncture needle, the downward movement of the rotating sleeve is used to push the puncture needle into the rubber strip, without manual puncture, which is more convenient to use and more practical; 5. By distinguishing between the upward and downward positions of the positioning rod, the gears are only meshed with the corresponding gears, thereby only driving the corresponding spiral hooks to rotate and move, and then only completing the removal of the corresponding rubber strips. In the case of not replacing all the rubber strips in the same installation frame, the corresponding rubber strips can be removed in a targeted manner, which is more convenient to use and more practical; 6. By cooperating the pull ring with the first groove and the second groove, the pull ring is placed in different grooves, so that the gear only meshes with the corresponding gear, thereby only driving the corresponding spiral hook to rotate and move, and then only completing the removal of the corresponding rubber strip. In the case of not replacing all the rubber strips in the same installation frame, the corresponding rubber strip can be removed in a targeted manner, which is more convenient to use and more practical.

[0031] like Figure 2 to Figure 8 As shown, a swing arm rubber strip removal device of the present invention comprises: A positioning frame 2 for positioning the installation frame 110, the positioning frame 2 is a hollow structure, a notch is provided on one side of the positioning frame 2, and a limiting frame 21 is provided on the upper part of the inner wall of the positioning frame 2; A mounting frame 3, the mounting frame 3 is fixedly mounted on the positioning frame 2; Four positioning rods 4, all of which are mounted on the mounting frame 3 and correspond to the positions of the rubber strips 13, and the positioning rods 4 are provided with external threads; A rotating sleeve 5 is screwed onto the positioning rod 4, and a spiral hook 50 is fixedly mounted on the lower end of the rotating sleeve 5. The spiral hook 50 has the same rotation direction as the external thread on the positioning rod 4; The motor 6 is fixedly mounted on the mounting frame 3 , and a gear 60 is transmission-mounted on the power output shaft of the motor 6 , and the gear 60 is meshed with the rotating sleeve 5 .

[0032] The motor 6 is a forward and reverse motor.

[0033] In fact, according to actual conditions, a unidirectional rotating motor 6 can be selected. When resetting, the rotating sleeve 5 can be reset manually. In this embodiment, the rotating sleeve 5 can be quickly reset by the forward and reverse rotation of the motor 6. At the same time, after the rubber strip 13 in the swing arm is pulled out, the rubber strip 13 can be held and the reverse rotation of the motor 6 can be used to make the spiral hook 50 unscrew the rubber strip 13, which is more convenient to use.

[0034] like Figure 6 and Figure 7 As shown, a sub-base 22 is fixedly provided on the inner wall of the limiting frame 21 at a position corresponding to the positioning rod 4 , and a puncture needle 23 for puncturing the adhesive strip 13 is installed on the sub-base 22 .

[0035] With such a structural design, the rubber strip 13 is punctured by the puncture needle 23, and when the motor 6 serving as a forward and reverse motor drives the spiral hook 50 to rotate in the opposite direction, so that the spiral hook 50 is screwed out of the rubber strip 13, the puncture needle 23 is used to fix the rubber strip 13 to the positioning frame 2, and there is no need to hold the rubber strip 13, which is more convenient to use.

[0036] like Figure 6 and Figure 7 As shown, a through hole 220 is opened on the auxiliary seat 22, and a round table 230 is fixedly provided in the middle of the puncture needle 23, and the round table 230 is located in the through hole 220; The through hole 220 is provided with a limiting ring 221 above and below the truncated cone 230; When the puncture needle 23 is pressed against the rubber strip 13, the upper end of the puncture needle 23 is located above the upper end surface of the auxiliary seat 22; When the rotating sleeve 5 is pressed against the upper end surface of the auxiliary seat 22 , the lower end of the puncture needle 23 is inserted into the rubber strip 13 .

[0037] In fact, according to actual conditions, it is also possible to choose a method such as directly fixing the puncture needle 23 on the auxiliary seat 22 to directly push the removal device to move in the direction of the rubber strip 13 to insert the puncture needle 23 into the rubber strip 13. In this embodiment, the puncture needle 23 is slidingly arranged and the downward movement of the rotating sleeve 5 is utilized to push the puncture needle 23 into the rubber strip 13. There is no need for manual puncture, which is more convenient to use and has strong practicality.

[0038] The positioning rod 4 is axially slidably mounted on the mounting frame 3; the axially slidable mounting here can be achieved by axially opening a positioning groove on the positioning rod 4 and providing a corresponding limit strip on the mounting frame 3, or by setting the upper end of the positioning rod 4 to a prism shape and providing a corresponding diamond-shaped hole on the mounting frame 3; When the positioning rod 4 moves upward to the upward position relative to the limiting frame 21, the rotating sleeve 5 corresponding to the positioning rod 4 is disengaged from the gear 60; When the positioning rod 4 moves downward to the lower position relative to the limiting frame 21, the rotating sleeve 5 corresponding to the positioning rod 4 meshes with the gear 60; A fixing mechanism is installed between the positioning rod 4 and the mounting frame 3 .

[0039] In fact, according to actual conditions, the positioning rod 4 can be directly fixed on the mounting frame 3. Each time the rubber strips 13 in the same mounting frame 110 are pulled out, all of them are pulled out. In this embodiment, the positioning rod 4 is in the upper position and the lower position, so that the gear 60 only meshes with the corresponding gear 60, thereby only driving the corresponding spiral hook 50 to rotate and move, and then only completing the removal of the corresponding rubber strip 13. In the case of not replacing all the rubber strips 13 in the same mounting frame 110, the removal of the corresponding rubber strip 13 can be completed in a targeted manner, which is more convenient to use and has strong practicality.

[0040] The fixing mechanism is a fixing bolt that is laterally screwed onto the mounting frame 3; The inner end of the fixing bolt abuts against the positioning rod 4.

[0041] The fixing bolts are used as a fixing mechanism to fix the positioning rod 4 and the mounting frame 3 , which has a simple structure, low cost and strong practicality.

[0042] The fixing mechanism is a transverse clamping rod transversely arranged on the mounting frame 3; The outer end of the transverse clamping rod is located outside the mounting frame 3, and an elastic mechanism for driving the transverse clamping rod to move in the direction of the positioning rod is installed between the transverse clamping rod and the mounting frame 3; The positioning rod 4 is provided with two positioning holes, and the positioning holes are located at different height levels of the positioning rod 4; When the transverse clamping rod is inserted into the positioning hole at the upper portion, the positioning rod 4 is located in the upward position; When the transverse clamping rod is inserted into the positioning hole at the lower portion, the positioning rod 4 is located at the downward position.

[0043] The lateral clamping rod is used as a fixing mechanism, and cooperates with the elastic mechanism and the positioning hole to complete the fixation between the positioning rod 4 and the mounting frame 3, which is simple to operate and easy to use.

[0044] The mounting frame 3 is provided with a through hole 30 at a position corresponding to the positioning rod 4, and the positioning rod 4 is inserted into the through hole 30; A pull ring 40 is fixedly provided at the upper end of the positioning rod 4; The upper end surface of the mounting frame 3 is provided with a first groove 31 and a second groove 32 at positions corresponding to the through hole 30, and the depth dimension of the first groove 31 is smaller than the depth dimension of the second groove 32; When the pull ring 40 is located in the first groove 31, the rotating sleeve 5 corresponding to the positioning rod 4 is disengaged from the gear 60; When the pull ring 40 is located in the second groove 32 , the rotating sleeve 5 corresponding to the positioning rod 4 is meshed with the gear 60 .

[0045] By cooperating 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 engages with the corresponding gear 60, thereby only driving the corresponding spiral hook 50 to rotate and move, and then only completing the removal of the corresponding rubber strip 13. In the case of not replacing all the rubber strips 13 in the same installation frame 110, the corresponding rubber strip 13 can be removed in a targeted manner, which is more convenient to use and has strong practicality.

[0046] A first retaining ring 41 is fixedly disposed in the through hole 30, and a second retaining ring 42 is fixedly mounted on the positioning rod 4; The positioning rod 4 is sleeved with a compression spring 43 between the first retaining ring 41 and the second retaining ring 42 .

[0047] By the cooperation between the compression spring 43 and the first and second retaining rings 41 and 42, the positioning rod 4 is pushed downward, which can make the pull ring 40 more easily inserted into the first groove 31 and the second groove 32, and the elastic force of the compression spring 43 can be used to temporarily fix the positioning rod 4, making it more convenient to use.

[0048] A handle 33 is also fixedly mounted on the upper end of the mounting frame 3 .

[0049] By setting the handle 33, after the spiral hook 50 is screwed into the rubber strip 13, the removal device can be pulled through the handle 33, thereby driving the rubber strip 13 to separate from the swing arm, which is more convenient to use and more practical.

[0050] In this embodiment, when in use, according to the position of the rubber strip 13 to be removed, the positioning rod 4 corresponding to the rubber strip 13 is pushed to the lower position, 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 is meshed with the gear 60; Then, the positioning frame 2 is attached to the corresponding installation frame 110, and the limiting frame 21 is pressed against the side of the installation frame 110 away from the installation seat 12, as shown in FIG. Figure 2 and Figure 3 ; The motor 6 is started, and the gear 60 drives the rotating sleeve 5 to rotate counterclockwise, thereby driving the spiral hook 50 to screw into the rubber strip 13 until the rotating sleeve 5 abuts against the upper end of the puncture needle 23; The rotating sleeve 5 continues to move, driving the puncture needle 23 to insert into the corresponding rubber strip 13. Figure 4 , Figure 5 and Figure 7 As shown; Grab the handle 33 and drive the removal device to move away from the swing arm, so as to drive the corresponding rubber strip 13 to separate from the swing arm. Figure 8 As shown; The motor 6 is controlled to rotate in the reverse direction, thereby driving the rotating sleeve 5 to rotate in the reverse direction (clockwise) through the gear 60, and the spiral hook 50 is screwed out of the rubber strip 13 in cooperation with the fixation of the rubber strip 13 by the puncture needle 23, and finally the rubber strip 13 is pulled off from the puncture needle 23.
