Description

Technical Field

[0001] This utility model belongs to the technical field of straw pellet production equipment, specifically relating to a packaging bag inverting device. Background Technology

[0002] After the straw pellets are produced, they are usually filled directly on the production line using a quantitative packaging machine. During the packaging process, when the weight of the pellets reaches the preset value, the automatic quantitative packaging machine will stop filling and then perform subsequent operations such as sealing, and then transport and transfer the packaging bags.

[0003] Currently, the transfer of packaging bags to the transport line usually involves using a bag-inverting device to push the filled packaging bags onto the transport line for easy transport later. These bag-inverting devices are typically located next to the conveyor belt. When a packaging bag moves over, a sensor detects it and the bag-inverting device then pushes the packaging bag onto another transport line for delivery.

[0004] However, the current bag-turning device is located next to the transport line and needs to be used in conjunction with sensors to identify when the transport belt of the packaging bag stops before it can be easily pushed onto another transport line. Sometimes, due to inconsistent states of the packaging bags after they come out, the bag-turning device may not accurately push the packaging bags over, which usually requires personnel to assist, resulting in poor production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a packaging bag inverting device to solve the problem of poor performance of previous inverting devices. The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a packaging bag inverting device, which includes: a base; A support base is disposed on the base; A support member is disposed on the support base, and the support member is used to place a packaging bag. The bottom of the support member is rotatably connected to the support base. A first driving device is rotatably disposed on the side of the support base away from the hinged part, the output end of the first driving device is hinged to the support part, and the first driving device is used to drive the support part to rotate. The bracket is mounted on the base; A second driving device is disposed on the top of the bracket. The second driving device is located above the support member, and the working end of the second driving device is used to extend toward the flipping direction of the support member. The third driving device is rotatably mounted on the output end of the second driving device; A connecting rod, the middle of which is hinged to the working end of the second driving device, the first end of which is rotatably connected to the output end of the third driving device, and the second end of which cooperates with the working end of the second driving device to clamp the top of the packaging bag.

[0006] Compared with existing technologies, the above technical solutions have the following beneficial effects: The support component set on the support base is used to directly support the packaging bag. After the packaging bag is filled, it falls directly onto the support component. Since the bottom of the support component is hinged to the support base, the first drive device pushes the support component upward, and the support component can flip to complete the inversion. Compared with the previous slapping push, the action is more accurate and there will be no misalignment problem. At the same time, the second drive device can extend outward when the support component flips, thereby pushing the upper position of the packaging bag. The third drive device, together with the connecting rod, can hold the upper part of the packaging bag. When pushed out, the connecting rod releases the packaging bag.

[0007] Based on the above technical solution, the embodiments of this application can be further improved as follows: In one embodiment, a lifting drive device is further included, which is disposed on the base. The support is disposed on the output end of the lifting drive device, and the lifting drive device is vertically disposed for raising or lowering the support member.

[0008] The lifting device can raise the height of the support component as a whole, making it easy to use in conjunction with other conveying equipment.

[0009] In one embodiment, a clamping plate is further provided on the actuating end of the second driving device, the clamping plate extending to both sides, and the clamping plate cooperates with the connecting rod to clamp the top of the packaging bag.

[0010] By setting up long strip-shaped clamps, the clamps and connecting rods can better clamp the top of the packaging bag.

[0011] In one embodiment, the third driving device is rotatably connected to the back of the clamping plate away from the packaging bag. The clamping plate has notches at both ends to avoid the connecting rod. The second end of the connecting rod extends through the notches to the front of the clamping plate. The third driving device is used to drive the connecting rod to rotate so that the second end is close to or away from the front of the clamping plate.

[0012] In one embodiment, two third driving devices and two connecting rods are provided respectively. The two third driving devices are symmetrically arranged on both sides of the working end of the second driving device, and the connecting rods are rotatably connected to both ends of the clamping plate.

[0013] In one embodiment, a conveying device is also included, wherein the base is disposed on a slide at the output end of the conveying device, and the conveying device is used to drive the base to reciprocate.

[0014] In one embodiment, the support member has a backrest on the side away from the hinged support base, the backrest being used to abut against the side of the packaging bag. Attached Figure Description

[0023] Example like Figure 1-3 As shown, the packaging bag inverting device provided by this utility model includes: a base 1, a support 2, a support member 3, a first driving device 4, a bracket 14, a second driving device 5, a third driving device 6, and a connecting rod 7.

[0024] The support base 2 is disposed on the base 1 and is used to provide support and hinge for the support member 3. Specifically, the support member 3 is disposed on the support base 2. The upper surface of the support member 3 is used to place the packaging bag. The bottom of the support member 3 is rotatably connected to the support base 2. The rotatable connection can be made by means of a hinge shaft or hinge, etc., and is fixed at the bottom of the support member 3 and the top side of the support base 2, so that the support member 3 can be flipped through this point.

[0025] The first driving device 4 is rotatably disposed on the side of the support base 2 away from the hinged part 3. Specifically, the first driving device 4 is fixed to the support base 2 on both sides by rotating seats. The output end of the first driving device 4 is hinged to the support part 3. The first driving device 4 is used to push the support part 3 to rotate. When the output end of the first driving device 4 extends, it pushes the support part 3 to flip and invert the bag. When the output end of the first driving device 4 retracts, the support part 3 falls back onto the support base 2, playing a supporting role.

[0026] The bracket 14 is disposed on the base 1, and the second driving device 5 is disposed on the top of the bracket 14. The second driving device 5 is located above the support 3. The working end of the second driving device 5 is used to extend towards the flipping direction of the support 3. When the second driving device 5 extends, the second driving device 5 can cooperate to push the upper part of the packaging bag. When the second driving device 5 retracts, the working end of the second driving device 5 is located directly above the packaging bag.

[0027] At this time, the third driving device 6 is rotatably mounted on the output end of the second driving device 5, and the middle part of the connecting rod 7 is hinged to the working end of the second driving device 5. The first end of the connecting rod 7 is rotatably connected to the output end of the third driving device 6, and the second end of the connecting rod 7 cooperates with the working end of the second driving device 5 to clamp the top of the packaging bag. By extending and retracting the third driving device 6, the connecting rod 7 is controlled to rotate around its middle part, thereby cooperating with the working end of the second driving device 5 to clamp the top of the packaging bag. When the second driving device 5 extends, the third driving device 6 pushes the connecting rod 7 to release.

[0028] The support member 3 set on the support base 2 is used to directly support the packaging bag. After the packaging bag is filled, it falls directly onto the support member 3. Since the bottom of the support member 3 is hinged to the support base 2, the first drive device 4 pushes the support member 3 upward, and the support member 3 can flip to complete the inversion. Compared with the previous slapping push, the action is more accurate and there will be no misalignment problem. At the same time, the second drive device 5 can extend outward when the support member 3 flips, thereby pushing the upper position of the packaging bag. The third drive device 6, together with the connecting rod 7, can hold the upper part of the packaging bag. When pushed out, the connecting rod 7 releases the packaging bag.

[0029] In this embodiment, a lifting drive device 8 is also included, which is disposed on the base 1. The support seat 2 is disposed on the output end of the lifting drive device 8. The lifting drive device 8 is vertically disposed for raising or lowering the support member 3, so that the lifting drive device 8 can raise the entire support seat 2, the support member 3 and the packaging bag. The lifting device can not only raise the height of the support member 3 as a whole, so that the support member 3 can be easily used in conjunction with other conveying equipment, but also the lifting device can repeatedly rise and fall during the filling of the packaging bag, raising the support member 3 to the point of slightly impacting the bottom of the packaging bag, so that the material inside the filling packaging bag is more compact.

[0030] To facilitate the cooperation between the connecting rod 7 and the working end of the second driving device 5 to clamp the packaging bag, a clamping plate 9 is also provided on the working end of the second driving device 5. The two ends of the clamping plate 9 extend to both sides. The clamping plate 9 cooperates with the connecting rod 7 to clamp the top of the packaging bag. The extended clamping plate 9 can cover the top of the entire packaging bag relatively completely. By setting the long strip clamping plate 9 and cooperating with the connecting rod 7 to fit the clamping plate 9, the clamping plate 9 and the connecting rod 7 can better clamp the top of the packaging bag.

[0031] Specifically, the third driving device 6 is rotatably connected to the back of the clamping plate 9 away from the packaging bag. The third driving device 6, located on the back of the clamping plate 9, does not affect the clamping plate 9 and the connecting rod 7 in clamping the packaging bag. The clamping plate 9 has notches 10 at both ends to avoid the connecting rod 7. The second end of the connecting rod 7 extends through the notches 10 to the front of the clamping plate 9. The notches 10 are designed to facilitate the passage of the connecting rod 7 without causing interference. The third driving device 6 is used to drive the connecting rod 7 to rotate so that the second end is close to or away from the front of the clamping plate 9. When the third driving device 6 extends, the second end of the connecting rod 7 is close to and fits against the clamping plate 9 to clamp the packaging bag. When the third driving device 6 retracts, the second end of the connecting rod 7 moves away from the clamping plate 9 and releases the packaging bag.

[0032] After the clamping plate 9 is lengthened, two third driving devices 6 and two connecting rods 7 are respectively provided. Since the middle part of the clamping plate 9 is connected to the working end of the second driving device 5, the third driving devices 6 and connecting rods symmetrically arranged at both ends of the clamping plate 9, so that the connecting rods 7 cooperate with both ends of the clamping plate 9 to clamp the sealing sides of the packaging bag. The two third driving devices 6 are symmetrically arranged on both sides of the working end of the second driving device 5. The main body of the third driving device 6 is hinged to the working end of the second driving device 5. The connecting rods 7 are rotatably connected to both ends of the clamping plate 9. By clamping at both ends, the connecting rods 7 can be quickly opened when the second driving device 5 is extended, so as to cooperate with the inverting of the packaging bag.

[0033] In this embodiment, the first driving device 4, the second driving device 5, and the third driving device 6 can be implemented using any driving device such as a cylinder, a hydraulic cylinder, or an electric actuator.

[0034] In this embodiment, a conveying device 11 is also included. The base 1 is disposed on the slide table 12 at the output end of the conveying device 11. The conveying device 11 is used to drive the base 1 to move back and forth. The conveying device 11 can be any driving device with a slide table 12. It is mainly used to move the base 1 together with the packaged items thereon back and forth, thereby conveying the packaging bag on the support 3 from one end of the conveying device 11 to the other end. This realizes the transportation of the packaging bag from the filling point to the discharge point, a single-point reciprocating transportation, which can avoid the inaccuracy problem of the previously continuously running conveyor belt transportation.

[0035] To ensure that the packaging bag is pushed over when the support 3 is flipped, a backrest 13 is provided on the side of the support 3 away from the hinged support 2. The backrest 13 extends upward and can be integrally formed with the support 3 to form an L-shaped structure on the side. The backrest 13 can abut against the side of the packaging bag when the support 3 is flipped, thus pushing the packaging bag over.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
