Description

Technical Field

[0001] This invention relates to the field of baler winding technology, and in particular to a baler winding anti-reverse device. Background Technology

[0002] In modern production line operations, baling machines are an important piece of equipment. The function of a baling machine is to package the produced wires into bundles to facilitate subsequent transportation of the wires. Existing baling machines are usually used together with take-up devices. During the operation, the wires first pass through the take-up device and then enter the baling machine, where the baling machine packages the wires into bundles.

[0003] When using a baler to pack wire, a take-up device is used in conjunction to feed the produced wire into the baler. However, during use, it often happens that the wire is not fed properly, and the take-up head clamp does not clamp the wire end, resulting in the wire not being fed properly. The wire feeding wheel spins freely, and when the take-up head does not clamp the wire, the wire may even rotate back, causing the entire wire to detach from the take-up device. In order to continue working, it is necessary to re-thread the wire, which takes a lot of time to complete the re-threading process and affects subsequent packing work. Summary of the Invention

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0026] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a device to prevent the winding of a baler from reversing. In this embodiment, a fixing member 204 is provided. The movement of the fixing member 204 drives the locking post 202 to move together, thereby locking the rotating wire and preventing the wire from moving further.

[0027] Specifically, the main mounting assembly 100 includes a housing 101, an accommodating cavity 102 disposed inside the housing 101, and a mounting post 103 disposed at the end of the housing 101; and the fixing assembly 200 includes a moving member 201, a locking post 202 disposed on the inner wall of the housing 101, a pushing member 203 disposed on the inner wall of the housing 101, and a fixing member 204 disposed at the end of the pushing member 203.

[0028] The mounting post 103 is fixedly installed at the bottom of the housing 101 to secure the housing 101. The mounting post 103 is installed on one side of the baler. The moving part 201 is located inside the housing 101. The locking post 202 is located on one side of the moving part 201. The fixing part 204 is located below the pushing part 203. The fixing part 204 drives the pushing part 203 to move upward. When the pushing part 203 moves upward, it pushes the locking post 202 to move upward. The locking post 202 approaches the moving part 201 and locks the wire.

[0029] In summary, during use, when the wire rotates back, the fixing ring 204a, which is fitted onto the outside of the wire, moves back along with the wire. When the fixing ring 204a moves upward, the second push rod 203d-3 connected to the outside of the fixing ring 204a drives the locking pin 202 to move upward along the movement groove 101a opened on the outer wall of the housing 101. The locking pin 202 approaches the movement roller 201b, at which point the wire is clamped and locked by the locking pin 202 and the movement roller 201b, and the wire can no longer move and stops rotating. At this time, the wire stays inside the take-up device. At this point, it is only necessary to continue pulling the wire into the clamp of the take-up head, without having to perform a whole set of re-threading operations. Example

[0030] Reference Figures 2-5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that the motion roller 201b is sleeved outside the fixed shaft 201c. When the wire is being wound up normally, the motion roller 201b rotates. When the wire is rotating back, the motion roller 201b cannot rotate. At this time, the wire is locked by the cooperation of the stationary motion roller 201b and the locking post 202.

[0031] Specifically, the outer wall of the housing 101 is provided with a movement groove 101a, and a bottom plate 101b is provided at the end of the housing 101. The movement groove 101a is provided on both sides of the housing 101 and is in the shape of an upward arc. The bottom plate 101b is provided at the bottom of the housing 101, and a wire through hole is provided on the surface of the bottom plate 101b. The wire passes through the wire through the wire through the hole and extends downward into the interior of the baler.

[0032] Preferably, the moving component 201 includes a fixed roller 201a disposed on the inner wall of the housing 101, and the moving component 201 also includes a moving roller 201b disposed on the inner wall of the housing 101. The fixed roller 201a is fixed to the inner wall of the housing 101, and the moving roller 201b and the fixed roller 201a are at the same horizontal height and also disposed inside the housing 101. The difference is that the fixed roller 201a is entirely fixed and cannot move, while the moving roller 201b has a fixed shaft 201c at its axis, and the moving roller 201b can rotate on the outer wall of the fixed shaft 201c.

[0033] The end of the motion roller 201b is provided with a mounting groove 201b-1, the inner wall of the mounting groove 201b-1 is provided with an array of motion teeth 201b-2, the center of the motion roller 201b is provided with a fixed shaft 201c, the outer wall of the fixed shaft 201c is provided with a motion block 201c-1, the outer wall of the motion block 201c-1 is provided with a motion rod 201c-2, and the end of the motion rod 201c-2 is provided with a first elastic element 201c-3.

[0034] The fixed shaft 201c is fixed to the inner wall of the housing 101 and cannot move. The moving roller 201b is sleeved on the outside of the fixed shaft 201c and rotates outside the fixed shaft 201c. Each end of the moving roller 201b is provided with a mounting groove 201b-1. An array of moving teeth 201b-2 is arranged in the inner circumference of the mounting groove 201b-1. One side of the moving teeth 201b-2 has a relatively gentle slope, and the other side has a slightly steep slope. The moving teeth 201b-2 rotate together with the moving roller 201b on the outside of the fixed shaft 201c as the moving roller 201b rotates.

[0035] Meanwhile, the array of moving blocks 201c-1 is arranged outside the fixed shaft 201c. A moving rod 201c-2 is connected to one side of the moving blocks 201c-1. The lower surface of the moving rod 201c-2 is connected to the first elastic element 201c-3. The first elastic element 201c-3 pushes one end of the moving rod 201c-2 upwards, bringing it into contact with the moving teeth 201b-2 on the inner wall of the moving roller 201b. When the moving roller 201b rotates counterclockwise, the upper surface of the moving rod 201c-2 contacts the relatively gentle slope of the moving teeth 201b-2. The relatively gentle slope of 1b-2 presses the moving rod 201c-2 downwards. At this time, the moving roller 201b can rotate on the outer surface of the fixed shaft 201c. When the moving roller 201b rotates clockwise, the first elastic element 201c-3 lifts one end of the moving rod 201c-2 upwards. At this time, the end of the moving rod 201c-2 comes into contact with the steeper slope of the moving tooth 201b-2. The moving rod 201c-2 is then engaged with the inner wall of the moving tooth 201b-2, thus locking the moving tooth 201b-2 and preventing the moving roller 201b from rotating.

[0036] Preferably, one end of the locking post 202 extends to the inner wall of the motion groove 101a and slides therewith, and the other end of the locking post 202 extends to the outer wall of the housing 101 and is provided with an anti-detachment plate 202a.

[0037] The outer surface of the locking pin 202 is rough and has a large frictional force. The locking pin 202 slides in the motion groove 101a on the outer surface of the housing 101. When the locking pin 202 is at the bottom of the motion groove 101a, the distance between the locking pin 202 and the motion roller 201b is relatively far. When the locking pin 202 is at the top of the motion groove 101a, the distance between the locking pin 202 and the motion roller 201b is relatively close.

[0038] In summary, during normal wire winding, the wire passes over the surface of the motion roller 201b, causing it to rotate counterclockwise. At this time, the motion roller 201b rotates outside the fixed shaft 201c. The motion rod 201c-2, located on the outer surface of the fixed shaft 201c, is pressed down by the gentle slope of the motion teeth 201b-2. When the wire rotates back, it causes the motion roller 201b to rotate clockwise. As the motion roller 201b rotates clockwise, the steep slope of the motion teeth 201b-2 contacts the raised end of the motion rod 201c-2. Because the fixed shaft 201c is fixed inside the housing 101 and cannot rotate, the motion rod 201c-2 does not move. At this point, the motion... When tooth 201b-2 is fixed, the moving roller 201b cannot rotate. When the wire rotates, the locking pin 202 will move upward from the bottom of the moving groove 101a. When the locking pin 202 moves to half the height of the moving groove 101a, the surface of the locking pin 202 contacts the wire. Since the outer surface of the locking pin 202 is relatively rough, it has friction. At this time, the locking pin 202 and the wire are driven to move upward in the moving groove 101a. The higher the locking pin 202 moves in the moving groove 101a, the more it contacts the wire, the greater the friction, and it will move closer to the moving roller 201b, thereby fixing the wire and clamping it between the locking pin 202 and the moving roller 201b, so that the wire does not continue to rotate. Example

[0039] Reference Figures 3-6 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that when the wire rotates upward, the fixing ring 204a moves upward along with the rotation of the wire, driving the second push rod 203d-3 to move upward, pushing the locking pin 202 to move upward, and clamping the wire.

[0040] Specifically, the pushing component 203 includes a fixed post 203a, a second elastic element 203a-1 is provided on the inner wall of the fixed post 203a, a connecting rod 203a-2 is also provided on the inner wall of the fixed post 203a, the second elastic element 203a-1 is sleeved on the outer wall of the connecting rod 203a-2, a connecting plate 203a-3 is provided at the end of the connecting rod 203a-2, a connecting post 203a-4 is provided on the end face of the connecting plate 203a-3, and a roller 203a-5 is hinged inside the connecting post 203a-4.

[0041] The fixed column 203a is fixed to the inner wall of the housing 101. The connecting rod 203a-2 is located inside the fixed column 203a. A second elastic element 203a-1 is provided outside the connecting rod 203a-2. When the connecting plate 203a-3 on one side of the connecting rod 203a-2 moves inward under force, it compresses the second elastic element 203a-1, causing the second elastic element 203a-1 to deform under compression. A connecting column 203a-4 is provided on the other side of the connecting plate 203a-3. A roller 203a-5 is hinged inside the connecting column 203a-4. The roller 203a-5 can rotate inside the connecting column 203a-4. When the roller 203a-5 is subjected to force, it will drive the connecting column 203a-4 to compress the connecting plate 203a-3, causing the second elastic element 203a-1 to deform under force.

[0042] Preferably, a fixing shell 203b is fitted on the outer wall of the fixing column 203a, a fixing groove 203b-1 is provided at the end of the fixing shell 203b, and a limiting column 203c is provided at the end of the fixing shell 203b.

[0043] The fixed shell 203b is fitted over the fixed post 203a. A fixed groove 203b-1 is provided on the surface of the fixed shell 203b to allow the components inside the fixed shell 203b to move. The limiting post 203c is fixed inside the shell 101 and passes through the surface of the fixed shell 203b.

[0044] The outer wall of the limiting post 203c is fitted with a fixing block 203d, the outer wall of the fixing block 203d is provided with an arc plate 203d-1, and the outer wall of the fixing block 203d is also provided with a first push rod 203d-2 and a second push rod 203d-3.

[0045] The fixing block 203d is sleeved on the outside of the limiting post 203c. An arc plate 203d-1 is provided on one side of the fixing block 203d. The arc surface of the arc plate 203d-1 is in contact with the roller 203a-5. A first push rod 203d-2 and a second push rod 203d-3 are provided on the other side of the fixing block 203d. The locking post 202 is located in the middle of the first push rod 203d-2 and the second push rod 203d-3. Both the first push rod 203d-2 and the second push rod 203d-3 have a certain curvature, which can better push the locking post 202 to move in the motion groove 101a.

[0046] The fixing member 204 includes a fixing ring 204a, which is connected to the end of the second push rod 203d-3. The inner wall of the fixing ring 204a is provided with a limiting groove 204b, the outer wall of the limiting groove 204b is provided with a ramp 204b-1, and the inner wall of the limiting groove 204b is provided with a third elastic member 204c.

[0047] The fixing ring 204a is connected to the bottom of the second push rod 203d-3. The fixing ring 204a is above the base plate 101b. The wire passes through the middle of the fixing ring 204a and through the wire hole of the base plate 101b. The fixing ring 204a has multiple limiting grooves 204b inside. The inner wall of the limiting groove 204b has a slope 204b-1. A third elastic element 204c is provided at the top of the limiting groove 204b. The locking block 204d in the limiting groove 204b is pushed downward by the third elastic element 204c.

[0048] Preferably, a locking block 204d is provided on the inner wall of the limiting groove 204b, an inclined surface 204d-1 is provided on the outer wall of the locking block 204d, a limiting hole 204d-2 is provided on the outer wall of the locking block 204d, a fourth elastic element 204e is provided on the inner wall of the limiting hole 204d-2, and a push plate 204e-1 is provided at the other end of the fourth elastic element 204e.

[0049] The locking block 204d has a slope 204d-1 on its side and a limiting hole 204d-2 on the other side. A fourth elastic element 204e is provided inside the limiting hole 204d-2 and a push plate 204e-1 is provided on the other side of the fourth elastic element 204e. The push plate 204e-1 is in contact with the slope 204b-1 of the inner wall of the limiting groove 204b.

[0050] When the wire passes through the fixing ring 204a, the wire contacts the inclined surface 204d-1 of the locking block 204d. When the wire moves downward, it presses the locking block 204d into the limiting groove 204b. At this time, the push plate 204e-1 contacts the ramp 204b-1, and the fourth elastic element 204e is deformed by compression. When the wire returns, the fourth elastic element 204e pushes the push plate 204e-1, which pushes the locking block 204d outward, pushing the bottom sharp corner of the inclined surface 204d-1 on the side of the locking block 204d to contact the wire, thereby causing the locking block 204d to move upward and compress the third elastic element 204c. At the same time, the contact between the sharp corner of the inclined surface 204d-1 on the side of the locking block 204d and the wire causes the fixing ring 204a to move upward together.

[0051] In summary, during use, when the wire retracts, the locking block 204d inside the retaining ring 204a is pushed towards the wire by the third elastic element 204c. The sharp corner below the inclined surface 204d-1 on the side of the locking block 204d contacts the wire, causing the locking block 204d to move upward. The locking block 204d moves on the slope 204b-1 inside the limiting groove 204b. The higher the locking block 204d moves, the more it contacts the wire, and the greater the clamping force on the wire, causing the retaining ring 204a to move with the wire. As the wire moves upward, the second push rod 203d-3 connected to the fixed ring 204a moves upward, causing the locking pin 202 to move upward. As the locking pin 202 moves upward and approaches the wire, the fixed block 203d rotates on the limiting pin 203c. The arc plate 203d-1 on the side of the fixed block 203d presses against the roller 203a-5. At this time, the roller 203a-5 is forced to move backward, causing the connecting plate 203a-3 to press against the second elastic element 203a-1 backward.
