[0031] The clamping working principle of the clamping mechanism of the present invention is as follows: applying external force to rotate the crank component 11 clockwise, driving the connecting rod component 12 to move downward, thereby pushing the slider 13 to move downward relative to the frame 2 and upward relative to the connecting rod component 12, thereby compressing the spring in the connecting component, and at the same time the rocker component 14 rotates counterclockwise and drives the clamping component 15 to press downward; when the external force is released, the spring releases the compression amount to both ends to clamp the entire clamping mechanism and reach a new equilibrium state.

[0032] Example 2

[0033] The clamping mechanism 1 of the present invention: the crank component 11 includes a rotating shaft 111, a crank block 112, and an operating rod 113; the rotating shaft 111 is installed in a hole on the frame 2, the operating rod 113 is sleeved on the rear end of the rotating shaft 111, the crank block 112 is sleeved on the front end of the rotating shaft 111, and the crank block 112 is connected to the connecting rod component 12.

[0034] By manually turning the joystick 113, the rotating shaft 111 will rotate counterclockwise or clockwise, driving the crank block 112 to rotate, thereby driving the connecting rod component 12 to move up and down, so that the clamping component can be loosened or tightened.

[0035] The crank component 11 further includes a hook 114 , which is fixed to the frame 2 by bolts. The operating rod 113 can be hooked by the hook 114 or can be released from the hook 114 .

[0036] Example 3

[0037] The clamping mechanism 1 of the present invention: the connecting rod component 12 includes a fisheye joint 125 and a spring assembly; the fisheye of the fisheye joint 125 is hinged to the crank block 112 through a pin, and the joint end is connected to the spring assembly through a thread.

[0038] The fisheye joint 125 realizes the connection between the crank component 11 and the connecting rod component 12, making the connection simpler and more reliable. The fisheye joint is a self-lubricating rod end joint bearing, which is a kind of joint bearing. Its function is to connect two rods whose center lines intersect, and the shaft installed in the "fisheye" can rotate around the center line by a certain angle. Therefore, the connecting piece here is not limited to the fisheye joint 125, and self-lubricating rod end joint bearings can be used.

[0039] Example 4

[0040] The clamping mechanism 1 of the present invention: the spring assembly includes a guide rod 121, an upper nut 122, and a spring 123; the lower section of the guide rod 121 is threaded through the step hole of the slider 13 and connected to the screw hole of the joint end of the fisheye joint 125, the spring 123 is sleeved in the middle of the guide rod 121, and its lower end is set within the large diameter of the slider 13, the upper nut 122 is screwed with the thread of the upper section of the guide rod 121 and is tightly pressed on the upper end surface of the spring 123.

[0041] When the crank component 11 drives the fisheye joint 125 to rotate, the guide rod 121 connected to the upper portion of the fisheye joint 125 moves up and down accordingly, thereby releasing or compressing the spring 123 .

[0042] The spring assembly further includes a lower nut 124 , which is screwed with a thread of the middle section of the guide rod 121 and is tightly pressed against the lower end surface of the slider 13 .

[0043] The functions of the lower nut 124 are: 1. The lower nut 124 is used in conjunction with the upper nut 122 to control the pre-compression force of the spring 123 by adjusting the installation distance between the two, thereby changing the clamping force of the clamping component; 2. Limiting the movement range of the positioning slider 13 on the guide rod 121.

[0044] Example 5

[0046] When the slide block 13 moves downward relative to the frame 2 , the left side of the rocker 141 moves downward via the short pin 142 , so that the rocker 141 rotates counterclockwise around the connecting shaft 143 .

[0047] Example 6

[0048] The clamping mechanism 1 of the present invention: the clamping component 15 includes multiple clamping wheels 151, a small mounting plate 152, and a large mounting plate 153; a plurality of clamping wheels 151 are connected to the front and rear small mounting plates 152 by bolts to form a clamping unit, the lower end of the large mounting plate 153 is connected to the clamping unit by bolts, and the upper end is hinged to the rocker 141 by a long pin shaft 144.

[0049] The rocker 141 rotates counterclockwise or clockwise around the connecting shaft 143, driving the clamping component 15 to move downward to clamp or move upward to release the baling line or other parts located therebelow.

[0050] The working process of the clamping mechanism is as follows: When the wire feeding unit of the automatic baler needs to be clamped, manually turn the joystick 113 clockwise (such as Figure 3 At the same time, the crank block 112 rotates to drive the guide rod 121 to move downward, the spring 123 is compressed and pushes the slider 13 to move downward relative to the frame 2, and the rocker 141 rotates counterclockwise around the connecting shaft 143 and drives the clamping component 15 to press downward until the operating rod 113 is hooked by the hook 114. After releasing the hand, the compressed spring 123 releases the compression to both ends to clamp the entire clamping mechanism and reach a new equilibrium state.

[0051] The advantages of the clamping mechanism of the present invention are: 1. It is operated by a manual joystick and does not require a hydraulic system to provide power, i.e., does not require a site for placing a hydraulic station. At the same time, its structure is simple and reliable, low in cost, and prevents hydraulic leakage from contaminating the product. 2. The pre-compression force of the spring can be controlled by adjusting the installation distance between the upper nut and the lower nut, thereby changing the clamping force of the clamping wheel group, which is convenient for debugging. 3. The clamping wheel group is hinged on the rocker, and each clamping wheel is installed by bolts. As a wearing part, it is convenient for maintenance and replacement.

[0052] Example 7

[0053] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the wire feeding unit of the automatic baling machine of the present invention includes a clamping mechanism 1, a motor 4, a reduction gear box 2, a wire feed wheel assembly 3, a plurality of wire feed wheels 5, and a conductor assembly 6; the motor 4 is mounted on the input end of the reduction gear box 2 through a flange, the wire feed wheel 5 is mounted on the output shaft of the reduction gear box 2, the wire feed wheel assembly 3 is mounted on the left end surface of the reduction gear box 2, the clamping mechanism 1 is mounted on the reduction gear box 2 and is located above the wire feed wheel 5, and the conductor assembly 6 is mounted on the reduction gear box 2 and is located between the wire feed wheel 5 and the clamping mechanism 1.

[0054] The working principle of the wire feeding unit of the automatic baling machine of the present invention is: when threading the baling wire, first operate the clamping mechanism 1 to make the clamping wheel 151 away from the wire feeding wheel 5; after the baling wire passes through the conductor assembly 6, operate the clamping mechanism 1 again to make the clamping wheel 151 approach the wire feeding wheel 5 until the baling wire is compressed; start the motor 4 to rotate the wire feeding wheel 5 through the reduction gear box 2; since the baling wire is compressed on the wire feeding wheel 5 by the clamping wheel 151, the wire feeding wheel 5 drives the baling wire forward through the friction force when rotating, thereby completing the wire feeding action.

[0055] The wire feeding unit of the automatic baler of the present invention is driven by a motor, has high energy conversion efficiency and electric energy is easy to obtain from the production site; a plurality of pairs of wire feeding wheels 151 and clamping wheels 5 are provided, and there are more contact points between the baling wire and the wire feeding unit during wire feeding, thereby ensuring the stability of the wire feeding action.

[0056] Example 8

[0057] The wire assembly 6 includes a wire guide I 61, a wire guide II 62, a plurality of wire guides III 63, and a sensor 64; the wire guide I 61 is arranged between the wire feed wheel assembly 3 and the leftmost wire feeding wheel 5, the wire guide II 62 is arranged on the right side of the rightmost wire feeding wheel 5, the wire guide III 63 is located in the space between the wire feeding wheel 5 and the clamping wheel 151, and the sensor 64 is arranged above the horizontal hole of the wire guide II 62.

[0058] Among them, wire guide I 61 , wire guide II 62 , and multiple wire guides III 63 are all provided with a horizontal hole, the hole diameter of which is slightly larger than the diameter of the baling wire, and the horizontal holes are coaxial during installation, and the axis line is tangent to the wire feeding wheel 5 .

[0059] When threading the baling wire, the baling wire passes through the wire feed wheel assembly, wire guide I 61, multiple wire guides III 63, and wire guide II 62 in sequence. When the baling wire reaches the wire guide II 62 and is detected by the sensor 64, the clamping mechanism is operated to make the clamping wheel 151 close to the wire feed wheel 5 until the baling wire is compressed.

[0060] Example 9

[0061] The reduction box 2 is a multi-stage transmission reduction box, on which are provided a plurality of output shafts 21 with the same rotation direction; the number of wire feeding wheels 5 is equal to the number of output shafts 21 and are installed on the output shafts 21; the number of clamping wheels 151 is equal to the number of wire feeding wheels 5 and are located above the wire feeding wheels 5; the number of wire guides III 63 is one less than the number of wire feeding wheels 5.

[0062] The reduction box 2 is of symmetrical structure, and a symmetrical wire feeding unit can be obtained by only changing the relative positions of the assembled parts, which simplifies the design and process and enhances the interchangeability between parts.

[0063] Multiple pairs of wire feeding wheels and clamping wheels ensure that there are more contact points between the baling wire and the wire feeding unit during wire feeding, making the wire feeding action smooth.

[0064] Example 10

[0065] The wire-in wheel assembly 3 includes two wire-in wheels 31 and a mounting frame 32 . The two wire-in wheels 31 are vertically mounted on the mounting frame 32 , and the mounting frame 32 is connected to the left end surface of the reduction box 2 by bolts.

[0066] The working process of the wire feeding unit of the present invention is: when threading the baling line, the joystick 113 is manually shaken to disengage from the hook 114, and the clamping wheel 151 is away from the wire feeding wheel 5. The baling line passes through the wire feed wheel 301, the wire guide I 61, multiple wire guides III 63, and the wire guide II 62 in sequence. When the baling line reaches the wire guide II 62 and is detected by the sensor 64, the joystick 113 is manually shaken until it is hooked by the hook 114, and the clamping wheel 151 approaches the wire feeding wheel 5 until the baling line is pressed. The motor 4 is started to rotate it, and the wire feeding wheel 5 is rotated through the reduction box 2. Since the baling line is pressed against the wire feeding wheel 5 by the clamping wheel 151, the wire feeding wheel 5 drives the baling line forward through friction when it rotates, thereby completing the wire feeding action. The wire feeding length can be calculated by detecting the encoder on the transmission shaft in the reduction box 2.

[0067] The advantages of the wire feeding unit of the automatic baling machine of the present invention are: 1. The wire feeding wheel is driven by a motor, the energy conversion efficiency is high and the electric energy is easy to obtain from the production site; there is no need to configure a hydraulic system to provide power, that is, there is no need to place a hydraulic station, and at the same time, its structure is simple and reliable, the cost is low, and hydraulic leakage and pollution of products are eliminated; 2.

The unit includes multiple pairs of wire feeding wheels and clamping wheels, which can be used for baling when feeding wires. There are many contact points between the wire and the wire feeding unit, which ensures the smoothness of the wire feeding action; Fourth, the clamping mechanism is operated by a manual joystick, and there is no need to configure a hydraulic system to provide power, that is, there is no need to place a hydraulic station. At the same time, its structure is simple and reliable, low cost, and prevents hydraulic leakage from contaminating the product; Fifth, the pre-compression force of the spring can be controlled by adjusting the installation distance between the upper nut and the lower nut, thereby changing the clamping force of the clamping wheel group, which is convenient for debugging; Sixth, the clamping wheel group is hinged on the rocker, and each clamping wheel is installed by bolts. As a wearing part, it is convenient for maintenance and replacement.

[0068] In short, the wire feeding unit of the automatic baler of the present invention no longer uses hydraulic components, has a simple and reliable structure, is low in cost, and eliminates hydraulic leakage that pollutes the product, thus adapting to the current development trend of energy conservation and consumption reduction.
