Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamping jaws, in particular to a feeding clamping jaw mechanism with variable angle. Background Art
[0002] When bagging and packaging products on small, non-standard equipment, improving feed positioning issues typically involves modifying the program to change the servo motor stroke or the bag opening positioning. Modifying the motor stroke or the opening positioning mechanism after the equipment is finished only offers limited optimization. By analyzing the bagging and packaging workflow and considering actual improvements, consider improving the gripper mechanism, adding another dimension to the problem-solving process.
[0003] Currently, when packaging small products, the feeding jaws are often mispositioned to deliver the materials into the packaging bag, which can easily cause the jaws to pierce the packaging bag, resulting in material waste and reduced production efficiency. To address this issue, the present invention provides a feeding jaw mechanism with a variable angle to solve the problem of material damage caused by mispositioning of the feeding jaws. Utility Model Content
[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a feeding clamp mechanism with a variable angle, which aims to solve the problem of material damage caused by inaccurate positioning of the feeding clamp.
[0005] The present invention solves the technical problem by employing a technical solution: a feed clamp mechanism with a variable angle, comprising a support rod, a universal joint, and a feed clamp. One end of the support rod is connected to a servo motor, the other end of the support rod is connected to the feed clamp, and the universal joint is mounted between the support rod and the feed clamp. The feed clamp and the support rod are rotatably connected via the universal joint. By adding a universal joint at the connection between the clamp cylinder and the support rod, the feed clamp can change its angle when encountering resistance during feeding. This effectively prevents packaging materials from being broken during operations such as bagging plastic bags, reduces material and labor waste caused by bag damage, and improves 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 clamping claw and the support rod, and the limiting step is fixed to the support rod by bolts.
[0007] As a further improvement to the present invention, the universal joint is located between the support rod and the limiting step. This universal joint allows the feed jaw to swing left and right within the angle reserved by the limiting step, while also serving as a guide, extending its service life. The limiting step is installed behind the feed jaw. The greater the slope of the limiting step, the greater the swing angle of the feed jaw.
[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, which 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.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The utility model adds a universal joint at the connection between the clamping cylinder and the support rod, so that the feeding clamp can change its angle when encountering resistance during feeding.

[0018] In this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any 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 that includes 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 clamp mechanism with variable angle includes a support rod 1, a universal joint 2 and a feeding clamp 3. One end of the support rod 1 is connected to the servo motor, and the other end of the support rod 1 is connected to the feeding clamp 3. The universal joint 2 is installed between the support rod 1 and the feeding clamp 3. The feeding clamp 3 is rotatably connected to the support rod 1 through the universal joint 2.
[0020] The support rod connects the servo motor and the feed jaw, serving as a support mechanism that facilitates the jaw's insertion into the bag during feeding. A universal joint, installed between the support rod and the feed jaw, allows the jaw to swing left and right, while also providing guidance and extending its service life. The feed jaw grips the material and feeds it into the bag.
[0021] By adding a universal joint at the connection between the gripper cylinder and the support rod, the feeding gripper can change its angle when encountering resistance during feeding. This can effectively avoid the packaging material from being broken when performing operations such as plastic bagging, 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 begins operating, driving the support rod. The rod and the feed jaws then move to the material location to grab the material. Once the material is grabbed, the system issues a fill command, causing the support rod and the feed jaws to move to the bag location and insert the material. If there is a positioning error at this point, the feed jaws may contact the bag wall. With the help of the universal joint, the jaws naturally deflect inwards. Once the servo motor reaches its desired position, the jaws release and exit the bag, awaiting the next system command.
[0023] This utility model is used for bagging materials in a vertical direction. By adding a universal joint behind the feeding clamp, if the servo motor positioning is not accurate enough during feeding, 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 burst.
[0024] A limiting step 4 is further 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 ladder. The universal joint can make the feeding clamp swing left and right within the reserved angle of the limiting ladder, 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 feed clamp 3 includes a connecting portion, a support portion 6, and a clamping portion 7. The connecting portion is connected to one end of the support portion, and the clamping portion is connected to the other end of the support portion. The connecting portion is located inside the limiting ladder and is rotatably connected to the universal joint. The rotatable connection between the connecting portion and the universal joint allows the feed clamp to achieve a certain swing angle.
[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 jaw is connected to a controller that 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, reducing the positioning accuracy requirements of the equipment servo motor and the packaging bag position.
[0030] By adjusting the structure of the feeding jaw mechanism, the utility model enables the feeding jaw to be angled during feeding, thereby reducing the risk of material damage caused by equipment positioning errors to a certain extent. The utility model can be applied to the feeding and loading mechanism of vertically operating equipment, improving the equipment operation status, reducing the product rejection rate, and solving the problem of material damage caused by inaccurate feeding jaw positioning.
[0031] The working principle of this utility model:
[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 exit the packaging bag and hang down naturally, waiting for the next material removal instruction.
[0035] Implementation Case 1:
[0036] A feeding clamp mechanism with variable angle includes a support rod 1, a universal joint 2 and a feeding clamp 3. One end of the support rod 1 is connected to a servo motor, and the other end of the support rod 1 is connected to the feeding clamp 3. The universal joint 2 is installed between the support rod 1 and the feeding clamp 3. The feeding clamp 3 is rotatably connected to the support rod 1 via the universal joint 2. The support rod connects the servo motor and the feeding clamp, and is a supporting mechanism that facilitates the clamp to extend into the packaging bag during feeding. The universal joint is installed between the support rod and the feeding clamp, allowing the feeding clamp to swing left and right, while also serving as a guide to extend its service life. The feeding clamp is used to clamp materials and feed them into the packaging bag. 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 prevent the packaging material from bursting when performing operations such as plastic bagging, reduce 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 running, 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 and the feeding clamp move to the packaging bag position and extend 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 utility model is used for vertical material bagging operations. By adding a universal joint behind the feeding clamp, if the servo motor positioning is not accurate enough 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 2 is installed between the support rod 1 and the feeding clamp 3. The feeding clamp 3 is rotatably connected to the support rod 1 via the universal joint 2. The support rod connects the servo motor and the feeding clamp, and is a supporting mechanism that facilitates the clamp to extend into the packaging bag during feeding. The universal joint is installed between the support rod and the feeding clamp, allowing the feeding clamp to swing left and right, while also serving as a guide to extend its service life. The feeding clamp is used to clamp materials and feed them into the packaging bag. 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 prevent the packaging material from bursting when performing operations such as plastic bagging, reduce 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 running, 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 and the feeding clamp move to the packaging bag position and extend 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 utility model is used for vertical material bagging operations. By adding a universal joint behind the feeding clamp, if the servo motor positioning is not accurate enough 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.
[0039] A limit step 4 is installed at the connection between the feed jaw and the support rod, secured to the support rod by bolts 5. A universal joint is located between the support rod and the limit step. This universal joint allows the feed jaw to swing left and right within the angle reserved by the limit step, while also serving as a guide and extending its service life. The limit step is installed behind the feed jaw. The steeper the limit step, the greater the swing angle of the feed jaw. In actual application, a limit step with an appropriate slope can be selected based on your needs.
[0040] Implementation Case 3:

The universal joint 2 is installed between the support rod 1 and the feeding clamp 3. The feeding clamp 3 is rotatably connected to the support rod 1 via the universal joint 2. The support rod connects the servo motor and the feeding clamp, and is a supporting mechanism that facilitates the clamp to extend into the packaging bag during feeding. The universal joint is installed between the support rod and the feeding clamp, allowing the feeding clamp to swing left and right, while also serving as a guide to extend its service life. The feeding clamp is used to clamp materials and feed them into the packaging bag. 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 prevent the packaging material from bursting when performing operations such as plastic bagging, reduce material and labor waste caused by damaged packaging bags, and improve the qualified rate of equipment products. When the system issues a command, the servo motor begins to operate, driving the support rod to move. 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 command, and the support rod and the feeding clamp move to the packaging bag position and extend into the packaging bag. If there is a positioning error at this time, the feeding clamp will contact the bag wall. With the help of the universal joint, the feeding clamp will naturally deflect into the bag. When the servo motor moves into position, the feeding clamp releases and exits the packaging bag, awaiting the next system command. This utility model is used for vertical material bagging operations. By adding a universal joint behind the feeding clamp, if the servo motor positioning is not accurate during feeding, the feeding clamp and the packaging bag will collide. The feeding angle can be changed within a certain limit to prevent the feeding clamp and the packaging bag from interfering and causing the packaging bag to burst. A limit step 4 is also provided at the connection between the feeding clamp and the support rod, and the limit step is fixed to the support rod by bolts 5. The universal joint is located between the support rod and the limit step. The universal joint allows the feed jaw to swing left and right within the angle reserved by the limit platform, while also serving as a guide, extending its service life. The limit platform is installed behind the feed jaw. The steeper the limit platform, the greater the swing angle of the feed jaw. In actual application, the limit platform with the appropriate slope can be selected according to needs.
