Technical Field

[0001] The invention relates to the technical field of clamping jaws, in particular to a feeding clamping jaw mechanism with variable angle. Background Art

[0002] When small non-standard equipment is used for product bagging and packaging, the problem of feeding positioning is improved by modifying the program to change the servo motor stroke or positioning the bag opening. Modifying the motor stroke or changing the opening positioning mechanism after the equipment is formed has limited optimization. Analyzing the workflow of product bagging and packaging, the improvement process in actual operation can be considered from the direction of improving the clamping mechanism to increase the dimension of problem solving.

[0003] At present, when a small-volume product is packaged, when a feeding clamp is used to feed the material into a packaging bag, the clamp is easily pierced through the packaging bag due to inaccurate positioning, resulting in waste of material and reduced production efficiency. To this end, the present invention provides a feeding clamp mechanism with a variable angle to solve the problem of material damage caused by inaccurate positioning of the feeding clamp. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a feeding clamp mechanism with a variable angle, aiming to solve the problem of material damage caused by inaccurate positioning of the feeding clamp.

By adding a universal joint at the connection between the jaw cylinder and the support rod, the feeding jaw can change its angle when encountering resistance during feeding, which can effectively avoid the packaging material from being broken when performing such as plastic bag bagging, reduce the material labor waste caused by the damage of the packaging bag, and improve the qualified rate of equipment products.

[0006] As a further improvement of the present invention: a limiting step is further provided at the connection between the feeding clamp and the support rod, and the limiting step is fixed to the support rod by bolts.

The universal joint can make the feeding clamp swing left and right within the reserved angle of the limiting step, and can also play a guiding role to extend the service life. The limiting step is installed behind the feeding clamp, and the greater the slope of the limiting step, the greater the swing angle of the feeding clamp.

[0008] As a further improvement of the present invention: the feeding clamp includes a connecting part, a supporting part and a clamping part, the connecting part is connected to one end of the supporting part, the clamping part is connected to the other end of the supporting part, the connecting part is located inside the limiting ladder, and the connecting part is rotatably connected to the universal joint.

[0009] As a further improvement of the present invention: the clamping portion includes a first clamping finger and a second clamping finger, and the first clamping finger and the second clamping finger are connected to the supporting portion.

[0010] As a further improvement of the present invention: the feeding jaw is connected to a controller, and the controller is electrically connected to the servo motor and the support rod. After the feeding jaw angle is changed, the support rod is guided by the controller, thereby reducing the positioning accuracy requirements of the equipment servo motor and the packaging bag position.

[0018] In this document, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. The present invention is further described in conjunction with the accompanying drawings and embodiments:

[0019] See also Figure 1-3 A feeding jaw mechanism with variable angle includes a support rod 1, a universal joint 2 and a feeding jaw 3, one end of the support rod 1 is connected to a servo motor, the other end of the support rod 1 is connected to the feeding jaw 3, the universal joint 2 is installed between the support rod 1 and the feeding jaw 3, and the feeding jaw 3 is rotatably connected to the support rod 1 through the universal joint 2.

[0020] The support rod connects the servo motor and the feeding jaws, which is a supporting mechanism. It is convenient for the jaws to extend into the packaging bag when feeding. The universal joint is installed between the support rod and the feeding jaws, so that the feeding jaws can swing left and right, and it can also play a guiding role and extend the service life. The feeding jaws are used to clamp the materials and feed them into the packaging bag.

[0021] By adding a universal joint at the connection between the clamp cylinder and the support rod, the feeding clamp can change its angle when encountering resistance during feeding. This can effectively avoid the packaging material from being broken when performing operations such as bagging with plastic bags, reduce material and labor waste caused by damaged packaging bags, and improve the qualification rate of equipment products.

[0022] When the system issues a command, the servo motor starts to run, driving the support rod to move, and the support rod and the feeding jaws move to the material position to clamp the material. After the material is clamped, the system sends a feeding command, and the support rod and the feeding jaws move to the packaging bag position and extend into the packaging bag. At this time, if there is a positioning error, the feeding jaws contact the bag wall, and with the assistance of the universal joint, the feeding jaws naturally deflect into the bag. When the servo motor moves to the right position, the feeding jaws release and exit the packaging bag, waiting for the next system command.

[0023] The present invention is used for bagging materials in the vertical direction. By adding a universal joint behind the feeding clamp, if the servo motor is not accurately positioned during feeding, the feeding clamp collides with the packaging bag, and the feeding angle can be changed within a certain limit to avoid interference between the feeding clamp and the packaging bag, which may cause the packaging bag to be broken.

[0024] A limiting step 4 is also provided at the connection between the feeding clamp and the support rod, and the limiting step 4 is fixed to the support rod by bolts 5.

[0025] The universal joint is located between the support rod and the limiting platform. The universal joint can make the feeding clamping claw swing left and right within the reserved angle of the limiting platform, and can also play a guiding role, thereby extending the service life.

[0026] A limiting ladder is installed behind the feeding clamp. The greater the slope of the limiting ladder, the greater the swing angle of the feeding clamp. In actual application, a limiting ladder with a suitable slope can be selected according to needs.

[0027] The feeding clamp 3 includes a connecting portion, a supporting portion 6 and a clamping portion 7, wherein the connecting portion is connected to one end of the supporting portion, the clamping portion is connected to the other end of the supporting portion, the connecting portion is located inside the limiting ladder, and the connecting portion is rotatably connected to the universal joint. The feeding clamp can obtain a certain swing angle through the rotatable connection between the connecting portion and the universal joint.

[0028] The clamping portion 7 includes a first clamping finger 8 and a second clamping finger 9 , and the first clamping finger 8 and the second clamping finger 9 are connected to the supporting portion 6 .

[0029] The feeding clamp is connected to a controller, which is electrically connected to the servo motor and the support rod. After the feeding clamp angle is changed, the support rod is guided by the controller, thereby reducing the positioning accuracy requirements of the equipment servo motor and the packaging bag position.

[0030] The present invention adjusts the structure of the feeding jaw mechanism so that the angle of the feeding jaw can be changed during feeding, thereby reducing the risk of material damage caused by equipment positioning error to a certain extent. The present invention can be applied to a feeding and filling mechanism of a vertically running equipment to improve the equipment operation state, reduce the product failure rate, and solve the problem of material damage caused by inaccurate positioning of the feeding jaw.

[0031] Working principle of the present invention:

[0032] (1) The system issues a material-picking command, and the feeding clamp grabs the material driven by the support rod.

[0033] (2) The system issues a feeding command, the support rod moves to the specified position, and the feeding claw carries the material into the packaging bag. If there is an error in the positioning of the packaging bag and the servo motor, the feeding claw contacts the bag wall. Through the action of the universal joint, the feeding claw can deflect left and right inside the limit ladder to avoid bursting the packaging bag.

[0034] (3) After the feeding is completed, the feeding jaws are released, the feeding jaws withdraw from the packaging bag and hang down naturally, waiting for the next material removal instruction.

The support rod connects the servo motor and the feeding jaw, and belongs to a supporting mechanism, which facilitates the jaw to extend into a packaging bag during feeding. The universal joint is installed between the support rod and the feeding jaw, so that the feeding jaw can swing left and right, and can also play a guiding role, thereby extending the service life. The feeding jaw is used to clamp the material and feed it into the packaging bag. By adding a universal joint at the connection between the jaw cylinder and the support rod, the feeding jaw can change its angle when encountering resistance during feeding, which can effectively avoid bursting the packaging material when performing operations such as plastic bag bagging, reduce the material and labor waste caused by damaged packaging bags, and improve the qualified rate of equipment products. When the system issues an instruction, the servo motor starts to run, driving the support rod to move, and the support rod and the feeding clamp move to the material position to clamp the material. After the material is clamped, the system sends a feeding instruction, and the support rod together with the feeding clamp moves to the packaging bag position and extends into the packaging bag. At this time, if there is an error in positioning, the feeding clamp contacts the bag wall, and with the assistance of the universal joint, the feeding clamp naturally deflects into the bag. When the servo motor moves into place, the feeding clamp releases and exits the packaging bag, waiting for the next system instruction. The present invention is used for material bagging operations in the vertical direction. By adding a universal joint behind the feeding clamp, if the servo motor is not accurately positioned during feeding, the feeding clamp collides with the packaging bag, and the feeding angle can be changed within a certain limit to avoid interference between the feeding clamp and the packaging bag, which causes the packaging bag to be broken.

The universal joint is installed between the support rod and the feeding jaw, so that the feeding jaw can swing left and right, and can also play a guiding role, thereby extending the service life. The feeding jaw is used to clamp the material and feed it into the packaging bag. By adding a universal joint at the connection between the jaw cylinder and the support rod, the feeding jaw can change its angle when encountering resistance during feeding, which can effectively avoid bursting the packaging material when performing operations such as plastic bag bagging, reduce the material and labor waste caused by damaged packaging bags, and improve the qualified rate of equipment products. When the system issues an instruction, the servo motor starts to run, driving the support rod to move, and the support rod and the feeding clamp move to the material position to clamp the material. After the material is clamped, the system sends a feeding instruction, and the support rod together with the feeding clamp moves to the packaging bag position and extends into the packaging bag. At this time, if there is an error in positioning, the feeding clamp contacts the bag wall, and with the assistance of the universal joint, the feeding clamp naturally deflects into the bag. When the servo motor moves into place, the feeding clamp releases and exits the packaging bag, waiting for the next system instruction. The present invention is used for material bagging operations in the vertical direction. By adding a universal joint behind the feeding clamp, if the servo motor is not accurately positioned during feeding, the feeding clamp collides with the packaging bag, and the feeding angle can be changed within a certain limit to avoid interference between the feeding clamp and the packaging bag, which causes the packaging bag to be broken.
