Description

Technical Field

[0001] The invention relates to a bag sealing device, in particular to a bag sealing device for protein powder production applied in the technical field related to material packaging. Background Art

[0002] Protein powder is a nutrient supplement that can improve human health. It is especially suitable for people who do not have enough protein intake. Protein powder was first used on athletes. It is used to control the weight of athletes and enhance their jumping ability.

[0003] In the protein powder production process, the sealed packaging of protein powder is involved. Generally, the bag mouth of the protein powder packaging bag is manually tied, but this method is very inefficient. Therefore, with the development of intelligent technology, many manufacturers use intelligent filling and sealing integrated design to replace manual operation to improve the sealing efficiency. For example, the Chinese patent specification with announcement number CN112938024A discloses a fully automatic solid powder granular material bag-in-bag high-speed packaging machine and the Chinese patent specification with announcement number CN210011906U discloses a bag filling and sealing integrated equipment.

[0004] However, integrated fully automatic powder packaging equipment often has the following problems: when filling protein powder, some protein powder is likely to spill at the bag mouth due to various reasons such as position deviation and vibration. When sealing, this part of the protein powder will be hot-pressed together with the bag mouth. Due to the influence of protein powder, it is easy to cause loose sealing, affecting the sealing after packaging and the normal storage time of the internal protein powder. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that during the packaging process, the powder and the bag opening are easily hot-pressed together, which affects the packaging effect.

[0006] To solve the above problems, the present invention provides a bag body sealing device for protein powder production, including a device body. A carrier plate is installed at the upper end of the device body through a chain. Along the running direction of the bag body, a transverse bag clamping plate, a sewing unit, a trimming unit, and a heat sealing machine are sequentially installed at the upper end of the carrier plate. A bag mouth groove is drilled in the middle of the transverse bag clamping plate. A powder blowing unit is fixedly connected to the upper end of the transverse bag clamping plate. The powder blowing unit includes two longitudinal air blowing strips with a plurality of evenly distributed air outlets. The two longitudinal air blowing strips are respectively located on both sides of the bag mouth groove and are fixedly connected to the transverse bag clamping plate. And air pumps are connected to the outer ends of the two longitudinal air blowing strips through air pipes. The transverse bag clamping plate, the powder blowing unit, the sewing unit, the trimming unit, and the heat sealing machine are all located above the conveyor belt for transporting the bag body. A tape bracket and a thread rack are also fixedly installed at the upper end of the carrier plate. The tape bracket and the thread rack are respectively located at the rear sides of the heat sealing machine and the powder blowing unit. The tape bracket is used for winding the hot melt tape, and the end of the hot melt tape is connected to the heat sealing port of the heat sealing machine. The thread rack is used for placing the sewing thread, and the end of the sewing thread is connected to the sewing end of the sewing unit; Transverse moving and vibrating material units are arranged on both sides of the powder blowing unit. The transverse moving and vibrating material units include two mating vibrating material frames fixedly connected to the upper end of the transverse bag clamping plate. And the two mating vibrating material frames are respectively located on both sides of the bag mouth groove. Each of the two mating vibrating material frames includes a positioning seat, a plurality of connecting rods fixedly connected to the upper end of the positioning seat, a plurality of electric push rods respectively arranged at the upper ends of the connecting rods, and a plurality of powder removing heads respectively arranged at the ends of the plurality of electric push rods. A high-definition camera is installed at one end of the sewing unit close to the transverse bag clamping plate, and the shooting end of the high-definition camera faces the adjacent transverse moving and vibrating material unit.

[0007] In the above bag body sealing device for protein powder production, through the combined setting of the longitudinal air blowing strips and the transverse moving and vibrating material units, before encapsulation, the bag mouth is first subjected to transverse local vibration treatment to make the floating powder fall off in advance, and then the longitudinal bag mouth can be blown to increase the shaking amplitude of the bag mouth, so that the floating powder further detaches from the bag body. Then, under the action of the high-definition camera, local re-vibration of the bag mouth can be carried out targeted. Compared with the prior art, the floating powder can be eliminated in all directions before the bag mouth is encapsulated, thereby effectively ensuring the encapsulation effect.

[0008] As a further improvement of the present application, in the same transverse moving and vibrating material unit, the number of powder removing heads at the upper end of one mating vibrating material frame is odd, and the number of powder removing heads at the upper end of the other mating vibrating material frame is even, and the multiple powder removing heads in the two mating vibrating material frames are alternately distributed. In the two transverse moving and vibrating material units, the two different mating vibrating material frames are obliquely cross-distributed.

[0009] As a further improvement of the present application, in the mating vibrating material frame with an even number of powder removing heads, a follower rod is fixedly connected between the extended end of the electric push rod and the corresponding powder removing head. The follower rod is made of an elastic material, and the fixed end of the electric push rod is directly fixedly connected to the connecting rod.

[0010] As a further improvement of the present application, in a mating shaking rack with an odd number of powder removal heads, the extended ends and fixed ends of the two electric push rods at the left and right edges are fixedly connected to the corresponding powder removal heads and connecting rods respectively, and the fixed ends and connecting rods of the remaining multiple electric push rods are connected via electric swivels, and an eccentric shaft is fixedly connected between the extended ends of the multiple electric push rods and the corresponding powder removal heads.

[0011] As a further improvement of the present application, a large diameter hole and a small diameter hole are drilled inside the extended end of the electric push rod, and the two are coaxially arranged. The self-eccentric shaft is located in the large diameter hole and the small diameter hole, and an electromagnetic sheet is fixedly embedded in the bottom of the large diameter hole, and the electromagnetic sheet corresponds to the self-eccentric shaft.

[0012] As a further improvement of the present application, the self-eccentric shaft includes a magnetic block located in the large diameter hole, a self-eccentric rod located in the small diameter hole, and a limit touch rod fixedly connected between the self-eccentric rod and the powder removal head. The magnetic block and the self-eccentric rod are fixedly connected to each other, and when the end of the magnetic block away from the powder removal head is adsorbed and fixed to the inner wall of the bottom of the large diameter hole, the limit touch rod and the extended end of the electric push rod collide with each other.

[0013] As a further improvement of the present application, the self-biasing rod includes a variable axis section and a fixed axis section fixedly connected to the variable axis section, the variable axis section is made of elastic material, the fixed axis section is a hard fixed structure, and the difference between the longitudinal span of the large diameter hole and the thickness of the magnetic block is greater than the length of the fixed axis section.

[0014] As a further improvement of the present application, when in use, the electric push rods on the two mating shaking frames of the same transverse shaking unit are controlled to extend so that multiple electric push rods are staggered with each other, and the vertical distance between the axes of two adjacent powder removal heads is not greater than 1 / 3 of the diameter of the powder removal heads, and the lateral spacing between two adjacent powder removal heads is not greater than the diameter of the powder removal heads.

[0015] In summary, through the coordinated setting of the longitudinal blowing air strip and the transverse shaking unit, the bag opening can be subjected to local transverse vibration treatment before packaging to achieve pretreatment of the floating powder at the bag opening, and then the bag opening can be blown longitudinally to increase the shaking amplitude of the bag opening, so that the floating powder can be further separated from the bag body. Afterwards, the high-definition camera can perform a visual re-inspection on it, and then the bag opening can be locally re-shaken in a targeted manner. Compared with the existing technology, the bag opening can eliminate floating powder in all directions before packaging, effectively ensuring that the powder is not easily directly packaged together with the bag opening during subsequent stitching and hot-melt bonding, thereby effectively ensuring the packaging effect.

DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1-3FIG. 1 shows a bag sealing device for producing protein powder. In the figure, a represents a transmission belt, which includes a device body 1. A load-bearing plate 2 is installed on the upper end of the device body 1 through a chain. When in use, the height of the load-bearing plate 2 can be adjusted according to the size of the bag, and then the distance between the load-bearing plate 2 and the bag opening can be adjusted. The specific driving structure can be selectively set according to actual needs. For example, a motor drives the chain through a gear. This is a well-known technology and will not be described in detail here. Along the direction of the bag running, the upper end of the load-bearing plate 2 is successively installed with a transverse clamp The bag plate 41, the stitching unit 43, the trimming unit 44 and the heat sealing machine 45, the middle part of the transverse bag clamping plate 41 is cut with a bag opening groove 402, the upper end of the transverse bag clamping plate 41 is fixedly connected with a powder blowing unit 42, the powder blowing unit 42 includes two longitudinal blowing air strips with a plurality of uniform air outlets, the two longitudinal blowing air strips are respectively located on both sides of the bag opening groove 402 and are fixedly connected to the transverse bag clamping plate 41, and the outer ends of the two longitudinal blowing air strips are connected to an air pump through an air pipe, the transverse bag clamping plate 41, the powder blowing unit 42, the stitching unit 43 and the heat sealing machine 45 are connected to the bag opening groove 402, and the bag opening groove 402 is cut with a bag opening groove 402, and the upper end of the transverse bag clamping plate 41 is fixedly connected with a powder blowing unit 42, and the powder blowing unit 42 includes two longitudinal blowing air strips with a plurality of uniform air outlets, and the two longitudinal blowing air strips are respectively located on both sides of the bag opening groove 402 and are fixedly connected to the transverse bag clamping plate 41. 3. The trimming unit 44 and the heat sealer 45 are both located above the conveyor belt for transporting the bag body. The upper end of the carrier plate 2 is also fixedly installed with a tape holder 51 and a wire rack 52. The tape holder 51 and the wire rack 52 are respectively located at the rear side of the heat sealer 45 and the powder blowing unit 42. The tape holder 51 is used to wind the hot melt tape, and the end of the hot melt tape is connected to the heat seal of the heat sealer 45. The wire rack 52 is used to place the sewing thread, and the end of the sewing thread is connected to the sewing end of the sewing unit 43. When in use, the filling The bag containing protein powder first enters the bag opening groove 402 under the action of the transmission belt, and then passes through the transverse shaking unit and the powder blowing unit 42. After the alternating vibration in the longitudinal and transverse directions, the floating powder at the bag opening can be removed, and then the bag opening is sewn at the sewing unit 43, and then reaches the trimming unit 44 to trim the bag opening to keep the bag opening flush, and finally reaches the heat sealing machine 45 to wrap the tape around the edge of the bag opening, and then the heat sealing machine 45 starts hot pressing to make the tape hot-melt to seal the bag opening to achieve sealing.

[0020] like Figure 4 , both sides of the powder blowing unit 42 are provided with a lateral shaking unit, the lateral shaking unit includes two juxtaposed shaking frames 6 fixedly connected to the upper end of the lateral clamping plate 41, and the two juxtaposed shaking frames 6 are respectively located on both sides of the bag opening groove 402, such as Figure 6 The two mating material shaking frames 6 each include a positioning seat 61, a plurality of connecting rods 603 fixedly connected to the upper end of the positioning seat 61, a plurality of electric push rods 62 respectively arranged at the upper ends of the connecting rods 603, and a plurality of powder removal heads 63 respectively arranged at the ends of the plurality of electric push rods 62. A high-definition camera 401 is installed at one end of the suture unit 43 close to the transverse bag clamping plate 41, and the shooting end of the high-definition camera 401 faces the adjacent transverse material shaking unit.

[0021] like Figure 4In the same transverse shaking material unit, the number of powder removing heads 63 on the upper end of one matched shaking material frame 6 is an odd number, and the number of powder removing heads 63 on the upper end of the other matched shaking material frame 6 is an even number, and the multiple powder removing heads 63 in the two matched shaking material frames 6 are alternately distributed. In the two transverse shaking material units, two different matched shaking material frames 6 are obliquely cross-distributed with each other. When in use, the electric push rods 62 on the two matched shaking material frames 6 of the same transverse shaking material unit are controlled to extend so that the multiple electric push rods 62 are staggered with each other, and the vertical distance between the axes of two adjacent powder removing heads 63 is not greater than 1 / 3 of the diameter of the powder removing heads 63, and the lateral spacing between two adjacent powder removing heads 63 is not greater than the diameter of the powder removing heads 63, which effectively ensures that the matched shaking material frame 6 with an even number of powder removing heads 63 can smoothly collide with the adjacent powder removing heads 63 when vibrating, thereby realizing lateral vibration of the bag mouth.

[0022] In this embodiment, a vibration motor is installed at the bottom of the positioning seat 61 with an even number of powder removal heads 63, and the powder removal heads 63 are directly connected to the ends of the electric push rods 62. Figure 5 When in use, the electric push rod 62 can be used to control the two opposite shaking frames 6 to extend toward the middle of the bag opening groove 402, so that the multiple powder removal heads 63 are opposite and cross-distributed, thereby driving the bag opening to present a wrinkled shape. At this time, the vibration motor is started to make the opposite shaking frame 6 with an even number of powder removal heads 63 vibrate continuously, so that it continuously hits the adjacent powder removal heads 63 across the bag opening, thereby achieving the effect of lateral vibration. Before the powder blowing unit 42 blows, the vibration pre-strike can be performed in advance, so that most of the floating powder can be vibrated and fall, so that the subsequent blowing of the powder When unit 42 blows the bag mouth to remove some of the residual floating powder, the amount of floating powder is small, and it is not easy for dust to spread excessively, effectively ensuring the environmental safety of the workshop. After two powder removals, the high-definition camera 401 can monitor visually. When some powder is not removed, another horizontal shaking unit can also remove the powder at a fixed point, thereby effectively ensuring the stability and sealing effect of the subsequent sealing. Through alternating vibrations in the longitudinal and transverse directions, the powder at the bag mouth can be greatly eliminated. Compared with the existing technology, the sealing effect is effectively guaranteed.

[0023] In summary, through the coordinated arrangement of the powder blowing unit 42 and the transverse shaking unit, before packaging, the bag opening is first subjected to a local transverse vibration treatment to make the floating powder fall in advance, and then the bag opening can be blown in the longitudinal direction to increase the shaking amplitude of the bag opening, so that the floating powder can be further separated from the bag body, and then under the action of the high-definition camera 401, the bag opening can be locally re-shaken in a targeted manner. Compared with the existing technology, the bag opening can eliminate floating powder in all directions before packaging, thereby effectively ensuring the packaging effect.

[0024] The second implementation method: This embodiment further improves the material shaking frame 6 on the basis of the first embodiment, and the rest of the parts are consistent with the first embodiment.

[0025] Figure 7 It is shown that in the coupled shaking material frame 6 with an even number of powder removal heads 63: a follower rod 8 is fixedly connected between the extended end of the electric push rod 62 and the corresponding powder removal head 63, the follower rod 8 is made of elastic material, and the fixed end of the electric push rod 62 is directly fixedly connected to the connecting rod 603. When it is hit by the powder removal head 63 on the corresponding coupling shaking material frame 6, it can swing left and right under the action of the follower rod 8, and then hit the wrinkled bag opening, thereby effectively expanding the vibration range of the bag opening and achieving a better powder removal effect on the bag opening.

[0026] In the matched shaking material rack 6 with an odd number of powder removal heads 63: the extended ends and fixed ends of the two electric push rods 62 at the left and right edges are fixedly connected to the corresponding powder removal heads 63 and the connecting rod 603 respectively, and the electric push rods 62 and powder removal heads 63 at the edges of both sides are mainly used for limiting, so that during the lateral vibration of the bag opening, the left and right swing amplitudes of the multiple matched shaking material racks 6 in the middle are not easy to be too large, thereby effectively ensuring that the bag opening is not easy to separate from the two matched shaking material racks 6, thereby effectively ensuring that the operation of first lateral and then longitudinal powder removal of the bag opening can be carried out stably, so that the overall sealing is not easily affected by the residual powder during the subsequent sealing; The fixed ends of the remaining multiple electric push rods 62 are connected to the connecting rod 603 through an electric swivel, and the extended ends of the multiple electric push rods 62 are fixedly connected to the corresponding powder removal heads 63 with a self-eccentric shaft, and the extended ends of the electric push rods 62 are drilled inside with a large diameter hole 601 and a small diameter hole 602, and the two are coaxially arranged, the self-eccentric shaft is located in the large diameter hole 601 and the small diameter hole 602, and the bottom of the large diameter hole 601 is fixedly inlaid with an electromagnetic sheet, and the electromagnetic sheet corresponds to the self-eccentric shaft, such as Figure 8 Under normal circumstances, the electromagnetic sheet can be controlled to be energized, thereby attracting the magnetic block 71, thereby pulling the eccentric shaft into the large diameter hole 601, so that the limit contact rod 73 is in a state of abutting against the extended end of the electric push rod 62. When powder removal is required, when the multiple powder removal heads 63 of the two matched shaking material racks 6 are controlled to be spaced apart from each other, such as Fig. 9 , the power can be turned off, at this time the eccentric shaft is in a relaxed state, such as Figure 10-11 Then, the electric swivel is controlled to rotate. Under the action of centrifugal force, the powder removal head 63 deviates from the axis of the electric push rod 62 and rotates, and then collides with the adjacent powder removal head 63 with the follower rod 8. The powder removal head 63 can swing left and right under the elastic action of the follower rod 8, thereby achieving the expansion vibration of the pleated bag opening, so that the powder removal effect on the bag opening is better.

[0027] The self-eccentric shaft includes a magnetic block 71 located in the large diameter hole 601, a self-biased rod 72 located in the small diameter hole 602, and a limit contact rod 73 fixedly connected between the self-biased rod 72 and the powder removal head 63. The magnetic block 71 and the self-biased rod 72 are fixedly connected to each other, and when the end of the magnetic block 71 away from the powder removal head 63 is adsorbed and fixed to the inner wall of the bottom of the large diameter hole 601, the limit contact rod 73 and the extended end of the electric push rod 62 are in conflict with each other. The self-biased rod 72 includes a variable shaft section 721 and a fixed shaft section 722 fixedly connected to the variable shaft section 721. The variable shaft section 721 is made of elastic material, and the fixed shaft section 722 is a hard and fixed structure. The difference between the longitudinal span of the diameter hole 601 and the thickness of the magnetic block 71 is greater than the length of the fixed shaft section 722, which effectively ensures that when the eccentric shaft is in a relaxed state, the elastic variable shaft section 721 can partially separate from the small diameter hole 602, so that it is located outside the extended end of the positioning seat 61, so that when it rotates, due to the action of centrifugal force, the powder removal head 63 can achieve eccentric rotation, thereby achieving impact on the bag opening and the adjacent powder removal head 63, so as to achieve better powder removal effect, and most of the powder can be vibrated away before the powder blowing unit 42 blows to remove powder, so that the amount of dust is smaller during the subsequent blowing to remove powder, and it is not easy to cause a large impact on the ambient air.

[0028] In summary, through the coordinated arrangement of the powder blowing unit 42 and the transverse shaking unit, the bag opening can be subjected to local transverse vibration treatment before packaging to achieve pretreatment of the floating powder at the bag opening, and then the bag opening can be blown longitudinally to increase the shaking amplitude of the bag opening, so that the floating powder can be further separated from the bag body. Afterwards, the high-definition camera 401 can perform a visual re-inspection on it, and then the bag opening can be locally re-shaken in a targeted manner. Compared with the existing technology, the bag opening can eliminate floating powder in all directions before packaging, effectively ensuring that the powder is not easily directly packaged together with the bag opening during subsequent stitching and hot-melt bonding, thereby effectively ensuring the packaging effect.

[0029] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
