Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging, in particular to a clamping and lifting device. Background Art

[0002] The carton clamping and lifting devices in most bagging machines on the market are mainly used to center, clamp, lift, lower and loosen cartons of various specifications that are in place on the roller line.

[0003] The carton clamping and lifting device includes a fixed frame and a loading platform for carrying the carton. The loading platform is slidably connected to the fixed frame to achieve the lifting and lowering of the loading platform. In the prior art, in order to clamp the carton tightly and centered on the loading platform, clamping plates are usually set on opposite sides of the loading platform to clamp the carton. However, since the two clamping plates are independent of each other during adjustment and do not interact with each other, the centering adjustment process is relatively cumbersome. In addition, for a single clamping plate, it is usually also difficult to achieve a horizontal fit of the two ends of the two clamping plates to the outer periphery of the carton by setting an adjustment handle at each opposite end of the clamping plate. As a result, it is difficult to fit the carton tightly and clamp it in the middle of the loading platform, affecting the bagging accuracy of the subsequent bagging process and affecting the lifting and lowering of the clamping and lifting device, which can easily cause the carton or other materials to be lifted to fall.

[0004] Therefore, it is urgent to solve the problem that the two clamping plates of the clamping and lifting device are difficult to fit together and clamp the cartons or other materials to be lifted in the center. Utility Model Content

[0005] In order to solve the deficiencies of the prior art, the present invention provides a clamping and lifting device, which avoids the problem that the two clamping plates are difficult to fit and clamp the material to be lifted in the center due to the lack of mutual linkage, while ensuring the stability of material lifting.

[0006] The technical effects to be achieved by the present invention are achieved through the following technical solutions:

[0007] The utility model provides a clamping and lifting device, comprising:

[0008] Fixed frame;

[0009] a loading assembly slidably connected to the fixing frame, the loading assembly comprising a loading platform and two clamping plates slidably disposed on the loading platform, with a placement area formed between the two clamping plates; and

[0010] An adjustment component includes an adjustment screw and two sliding drive members, and opposite thread grooves are respectively provided at both ends of the adjustment screw. The sliding drive members are respectively screwed to the two ends of the adjustment screw, and the two sliding drive members are respectively connected to the two clamps. By rotating the adjustment screw, the two clamps can be parallel to each other along the loading platform and simultaneously approach or move away from the placement area.

[0011] In some implementations, the adjustment assembly further includes an adjustment drive member, which is disposed at an end of the adjustment screw and is in driving connection with the adjustment screw to rotate the adjustment screw.

[0012] In this implementation, the end of the adjusting screw is connected to the power output end of the adjusting drive. By controlling the adjusting drive, the adjusting drive drives the adjusting screw to rotate, thereby driving the sliding drive members respectively arranged at both ends of the adjusting screw to move relative to the loading platform.

[0013] In some implementations, a clamping mechanism is provided between the clamping plate and the sliding drive member, and the clamping mechanism includes:

[0014] a clamping bracket connected to the sliding drive member; and

[0015] The clamping drive member is connected to the clamping bracket, and the clamping drive member is also drivingly connected to the clamping plate to drive the clamping plate to move in a direction parallel to the moving direction of the sliding drive member.

[0016] In this implementation, after the two sliding drive members drive the two clamping plates to clamp the material to be lifted, the clamping drive member drives the clamping plates to move in a direction parallel to the moving direction of the sliding drive members, so that the clamping plates further clamp the material to be lifted.

[0017] In some implementations, the clamping mechanism further includes a guide post, which passes through the clamping bracket and is fixedly connected to the clamping plate.

[0018] In some implementations, the adjustment drive member includes a rotor, a first right-angle gear, and a second right-angle gear, wherein the first right-angle gear is connected to the rotor, and the second right-angle gear is connected to the end of the adjustment screw and meshes with the first right-angle gear.

[0019] In some implementations, the loading assembly further includes a sliding structure, and the two clamps are connected to the loading platform by relative sliding means.

[0020] In some implementations, the sliding structure includes a first slide rail connected to the loading platform and first sliders respectively connected to the two clamping plates, and the first sliders are slidably connected to the first slide rail.

[0021] In some implementations, there are multiple first slide rails, and multiple first sliding blocks are arranged in parallel with the sliding drive member.

[0022] In this implementation, multiple first slide rails are arranged in parallel on the loading platform, multiple first sliders are slidably connected to the multiple first slide rails in a one-to-one manner, and the sliding drive member is arranged between the multiple first sliders and parallel to the first sliders, so that multiple points of the splint are connected to the first sliders, thereby improving the stability of the splint clamping the material to be lifted and the clamping force is stronger.

[0023] In some implementations, a support column is provided on a side of the splint facing away from the placement area.

[0024] In some implementations, it further includes a lifting drive assembly and a lifting sliding assembly, the carrier assembly is slidably connected to the fixed frame through the lifting sliding assembly, and the lifting drive assembly drives the carrier assembly to rise and fall along the fixed frame.

[0025] In summary, the present invention has at least the following advantages:

[0026] The clamping and lifting device provided by the utility model has two sliding drive members arranged at both ends of the same adjusting screw rod. The rotation of the adjusting screw rod drives the two sliding drive members to make relative movement on the loading platform, thereby driving the two relatively arranged clamping plates to simultaneously approach or move away from the placement area. The two clamping plates are linked to each other, and both clamping plates are in contact with the outer periphery of the material to be lifted, thereby ensuring that the material to be lifted is clamped on the designed center line, that is, the middle of the placement area. The adjusting screw rod has a self-locking function, so that the two clamping plates will not move after being adjusted into place due to the influence of external forces, thereby avoiding the problem of difficulty in clamping the material to be lifted in the center due to the two clamping plates not being linked to each other, and at the same time ensuring the stability of material lifting.

[0038] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] Please see the attached Figure 1 ~Attached Figure 2 The clamping and lifting device of the present invention includes a fixing frame 1, a loading component 2 and an adjusting component 3.

[0042] Please combine Figure 1 and Figure 2 , Figure 1 The diagram shows the structural relationship between the fixing frame 1, the object-carrying assembly 2 and the adjusting assembly 3 in the embodiment of the present utility model. Figure 2The diagram illustrates the structural relationship between the adjusting screw 31, the sliding drive member 32, and the two clamping plates 22 in an embodiment of the present invention. Specifically, the loading assembly 2 is slidably connected to the fixed frame 1. The loading assembly 2 includes a loading platform 21 and two clamping plates 22 slidably disposed on the loading platform 21, with a placement area 23 formed between the two clamping plates 22. The adjusting assembly 3 includes an adjusting screw 31 and two sliding drive members 32. The adjusting screw 31 has mutually opposite thread grooves 311 at both ends. The sliding drive members 32 are respectively screwed to the two ends of the adjusting screw 31, and the two sliding drive members 32 are respectively connected to the two clamping plates 22. By rotating the adjusting screw 31, the two clamping plates 22 can be moved parallel to each other along the loading platform 21 and simultaneously approach or move away from the placement area 23.

[0043] In this embodiment, the ends of the adjusting screw 31 are provided with mutually opposite thread grooves 311, and two sliding drive members 32 are respectively screwed to the forward and reverse thread grooves 311. By rotating the adjusting screw 31, the two sliding drive members 32 are caused to move relative to each other, thereby driving the two clamping plates 22 to move relative to each other on the loading platform 21, simultaneously approaching or moving away from the placement area 23, thereby clamping the material to be lifted centered on the placement area 23, that is, in the middle of the loading platform 21, further ensuring the bagging accuracy of the subsequent bagging process. Because the two clamping plates 22 are arranged on the same adjusting screw 31, when the adjusting screw 31 is rotated, the sliding drive members 32 screwed to the ends of the adjusting screw 31 move synchronously, ensuring that both clamping plates 22 clamp the material to be lifted simultaneously, and the ends of a single clamping plate 22 are parallel to the material to be lifted, thereby ensuring the stability of the material to be lifted on the loading platform 21. Preferably, the adjusting screw 31 is a rectangular trapezoidal screw with a self-locking function, so that the two clamping plates 22 will not move due to external forces after being adjusted into place, further ensuring the reliability of the clamping and lifting device. Preferably, the material to be lifted can be a box; the adjusting screw 31 is a left and right forward and reverse screw.

[0044] The above-mentioned clamping and lifting device has two sliding drive members 32 arranged at both ends of the same adjusting screw 31. The adjusting screw 31 rotates to drive the two sliding drive members 32 to move relative to each other on the loading platform 21, thereby driving the two relatively arranged clamps 22 to approach or move away from the placement area 23 at the same time. The two clamps 22 are linked to each other, and both clamps 22 are in contact with the outer periphery of the material to be lifted, thereby ensuring that the material to be lifted is clamped in the designed center line, that is, the middle of the placement area 23, and the adjusting screw 31 has a self-locking function, so that the two clamps 22 after being adjusted into place will not move due to the influence of external forces, thereby avoiding the problem that the two clamps 22 are difficult to fit in the center to clamp the material to be lifted due to the lack of linkage, and at the same time ensuring the stability of material lifting.

[0045] In some preferred embodiments, please continue to see Figure 2 , Figure 2The diagram illustrates the structural relationship between the adjustment drive member 33 and the adjustment screw 31 in an embodiment of the present invention. Specifically, the adjustment assembly 3 further includes an adjustment drive member 33, which is disposed at the end of the adjustment screw 31 and is in transmission connection with the adjustment screw to rotate the adjustment screw 31. The end of the adjustment screw 31 is connected to the power output terminal of the adjustment drive member 33. By controlling the adjustment drive member 33, the adjustment drive member 33 drives the adjustment screw 31 to rotate, thereby driving the sliding drive members 32, respectively disposed at both ends of the adjustment screw 31, to move relative to the loading platform 21. This in turn drives the two clamping plates 22 to simultaneously move toward or away from the placement area 23, thereby improving the centering reliability of the two clamping plates 22. When the two clamping plates 22 clamp the material to be lifted in the middle of the placement area 23, the power to the adjustment drive member 33 is cut off, stopping the rotation of the adjustment screw 31. The adjustment screw 31 has a self-locking function, which fixes the two clamping plates 22 to the loading platform 21, thereby ensuring clamping stability. Preferably, the adjustment drive member 33 can be a motor or a cylinder.

[0046] In some preferred embodiments, please continue to see Figure 2 , Figure 2 The diagram illustrates the structural relationship between the clamping bracket 241, the clamping driver 242, and the clamping plate 22 in an embodiment of the present invention. Specifically, a clamping mechanism 24 is disposed between the clamping plate 22 and the sliding driver 32. The clamping mechanism 24 comprises a clamping bracket 241 and a clamping driver 242. The clamping bracket 241 is connected to the sliding driver 32; the clamping driver 242 is connected to the clamping bracket 241. The clamping driver 242 is also connected to the clamping bracket 241. The clamping driver 242 is also operatively connected to the clamping plate 22, thereby driving the clamping plate 22 in a direction parallel to the direction of movement of the sliding driver 32.

[0047] In this embodiment, after the two sliding drive members 32 drive the two clamping plates 22 to clamp the material to be lifted, the clamping drive member 242 drives the clamping plates 22 to move in a direction parallel to the movement direction of the sliding drive member 32, so that the clamping plates 22 further clamp the material to be lifted. Specifically, the clamping bracket 241 is connected to the sliding drive member 32, and the clamping plates 22 are connected to the side of the clamping assembly near the placement area 23 via the clamping drive member 242. The clamping drive member 242 is driven and connected to the clamping plates 22. The movement of the sliding drive member 32 drives the clamping bracket 241, the clamping drive member 242, and the clamping plates 22 to move simultaneously. After the clamping plates 22 contact the material to be lifted, the clamping drive member 242 drives the clamping plates 22 to further clamp the material to be lifted, thereby ensuring the stability of the material to be lifted.

[0048] In some preferred embodiments, the clamping mechanism 24 further includes a guide post 243, which is disposed through the clamping bracket 241 and fixedly connected to the clamping plate 22. The two guide posts 243 are connected to opposite ends of the clamping bracket 241 and the clamping plate 22, respectively. Specifically, the first guide post 243 connects the clamping assembly to the first end of the clamping plate 22, and the second guide post 243 connects the clamping assembly to the second end of the clamping plate 22. These guide posts 243 exert equal clamping force on the opposite ends of the clamping plate 22, preventing deformation of the clamping plate 22. This ensures that both ends of the clamping plate 22 have consistent clamping force on the material to be lifted, improving the clamping effect without damaging the material to be lifted. Of course, multiple guide posts 243 can also be provided to increase the clamping force on the material to be lifted at various points on the clamping plate 22. Preferably, the guide posts 243 may be linear bearings.

[0049] In some more preferred embodiments, the adjustment drive member 33 includes a rotor 331, a first right-angle gear 332, and a second right-angle gear 333. The first right-angle gear 332 is connected to the rotor 331, and the second right-angle gear 333 is connected to the end of the adjustment screw 31 and meshes with the first right-angle gear 332. The first right-angle gear 332 and the second right-angle gear 333 cooperate to enable the adjustment drive member 33 to drive the adjustment screw 31 to rotate. Through this cooperation, while ensuring the normal operation of the adjustment screw 31, the space occupied by the adjustment drive member 33 is also compressed, so that the adjustment drive member 33 occupies a smaller space in the clamping and lifting device, is more convenient for adjustment, and has a tight structure, thereby ensuring the tightness of the clamping plate 22.

[0050] Example 2:

[0051] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the clamping and lifting device of the utility model. Figure 3 ~Attached Figure 4 .

[0052] Among them, see Figure 3 , Figure 3 The diagram shows the structural relationship among the loading platform 21, the sliding structure 25 and the clamping plates 22 in the embodiment of the present invention. Specifically, the loading assembly 2 further includes the sliding structure 25, and the two clamping plates 22 are connected to the loading platform 21 by relative sliding connection with each other through the sliding structure 25.

[0053] In this embodiment, when the adjusting screw 31 rotates, the two clamps 22 move relative to each other on the loading platform 21 through the sliding structure 25. The sliding structure 25 makes the sliding connection between the two clamps 22 and the loading platform 21 smoother, thereby making the two clamps 22 more smoothly and stably approach or move away from the placement area 23, further ensuring the reliability of the two clamps 22 clamping the material to be lifted.

[0054] In some preferred embodiments, the sliding structure 25 includes a first slide rail 251 connected to the loading platform 21 and first sliders 252 respectively connected to the two clamping plates 22, and the first sliders 252 are slidably connected to the first slide rail 251. The clamping plate 22 is connected to the first slider 252, and the first slider 252 is slidably connected to the first slide rail 251, so that the clamping plate 22 is slidably connected to the loading platform 21. The two clamping plates 22 are respectively connected to the first slider 252, that is, one clamping plate 22 is correspondingly connected to one first slider 252, so that the clamping plate 22 is slidably connected to the first slide rail 251 through the first slider 252, thereby making the two clamping plates 22 move relative to each other on the loading platform 21, thereby ensuring the reliability of the sliding of the clamping plates 22.

[0055] In some preferred embodiments, there are multiple first rails 251, and multiple first sliders 252 are arranged parallel to the sliding drive member 32. Multiple first rails 251 are arranged parallel to the loading platform 21, and multiple first sliders 252 are slidably connected to the multiple first rails 251 in a one-to-one correspondence. The sliding drive member 32 is arranged between the multiple first sliders 252 and parallel to the first sliders 252, so that the clamping plate 22 is connected to the first sliders 252 at multiple points, thereby improving the stability of the clamping plate 22 in clamping the material to be lifted and strengthening the clamping force. In this embodiment, three first rails 251 are provided on the loading platform 21, corresponding to three first sliders 252. A sliding drive member 32 is arranged between the three first sliders 252 and parallel to the first sliders 252. An adjusting screw 31 is arranged between the three first rails 251 and parallel to the first rails 251 to ensure that the clamping plate 22 fits tightly and clamps the material to be lifted.

[0056] In some more preferred embodiments, see Figure 4 , Figure 4 The diagram illustrates the structural relationship between the clamping plate 22 and the support column 221 in an embodiment of the present invention. Specifically, the support column 221 is provided on the side of the clamping plate 22 facing away from the placement area 23. This supports the clamping plate 22. Specifically, the support column 221 is provided at the connection between the clamping plate 22 and the first slider 252 and / or the connection between the clamping plate 22 and the sliding drive 32, supporting and securing the clamping plate 22 while also strengthening the clamping force of the clamping plate 22.

[0057] Example 3:

[0058] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the clamping and lifting device of the utility model. Figure 5 .

[0059] Among them, see Figure 5 , Figure 5The diagram illustrates the structural relationship between the fixed frame 1, the lifting and sliding assembly 5, and the carrier assembly 2 in an embodiment of the present invention. Specifically, the clamping and lifting device also includes a lifting drive assembly 4 and a lifting and sliding assembly 5. The carrier assembly 2 is slidably connected to the fixed frame 1 via the lifting and sliding assembly 5. The lifting drive assembly 4 drives the carrier assembly 2 up and down along the fixed frame 1.

[0060] In this embodiment, the carrier assembly 2 is slidably connected to the fixed frame 1 through the lifting sliding assembly 5, ensuring the reliability of the carrier assembly 2 being lifted and lowered along the fixed frame 1. Specifically, a second slide rail 51 is provided on the fixed frame 1, and a second slider 52 slidably connected to the second slide rail 51 is provided at the connection between the carrier assembly 2 and the fixed frame 1. The lifting drive assembly 4 drives the carrier assembly 2 to move, and the second slider 52 slides and cooperates with the second slide rail 51 to enable the carrier assembly 2 to be smoothly lifted and lowered along the fixed frame 1. Preferably, the lifting drive assembly 4 includes a synchronous belt and a motor, and the synchronous belt cooperates with the motor to drive. The synchronous belt is connected to the fixed frame 1, and the carrier assembly 2 is connected to the synchronous belt. The motor drives the synchronous belt transmission, thereby driving the carrier assembly 2 to be lifted and lowered along the fixed frame 1 through the lifting sliding assembly 5, thereby improving the reliability of the overall structure.

[0061] The clamping and lifting device of the present invention has two sliding drive members 32 arranged at both ends of the same adjusting screw rod 31. The adjusting screw rod 31 rotates to drive the two sliding drive members 32 to move relative to each other on the loading platform 21, thereby driving the two relatively arranged clamping plates 22 to simultaneously approach or move away from the placement area 23. The two clamping plates 22 are linked to each other, and both clamping plates 22 are in contact with the outer periphery of the material to be lifted, thereby ensuring that the material to be lifted is clamped in the designed center line, that is, the middle of the placement area 23. The adjusting screw rod 31 has a self-locking function, so that the two clamping plates 22 will not move after being adjusted into place due to the influence of external forces, thereby avoiding the problem that the two clamping plates 22 are difficult to fit in the center to clamp the material to be lifted due to the lack of linkage, and at the same time ensuring the stability of material lifting.
