Description

Technical Field

[0001] This application relates to the field of packaging bag manufacturing, and in particular to a bag support device. Background Technology

[0002] Composite bags are created by combining films of different materials (such as plastic, paper, or aluminum foil) into a single structure through specific processes (such as dry lamination or thermoforming). This achieves comprehensive performance that is difficult to attain with single-layer materials, meeting the packaging needs of various products. Composite bags typically consist of two or more layers of bags nested together. The manufacturing process involves placing the outer bag over the inner bag to complete the assembly.

[0003] During the assembly of composite bags, a bag support device is usually required. The bag support device typically includes a support frame that matches the size of the composite bag. Two or more bags are sequentially nested on the support frame from the inner layer to the outer layer, thereby completing the nesting of two or more layers of bags.

[0004] However, when it is necessary to assemble composite bags of different sizes, the same support frame is difficult to match bags of different sizes. When the size of the support frame and the bag do not match, it is difficult to complete the fitting of the inner and outer bags in a relatively regular manner. Summary of the Invention

[0005] To facilitate the relatively orderly assembly of composite bags of different sizes, this application provides a bag-packing support device.

[0006] The bagging support device provided in this application adopts the following technical solution: A bagging support device includes a support plate and a support frame fixed on the support plate. The support frame includes two vertically arranged telescopic rods mounted on the support plate. Each telescopic rod has an adjusting rod hinged to its upper end. The two adjusting rods extend towards each other and are hinged to each other. The two adjusting rods gradually tilt downwards in the direction of approaching each other. One of the telescopic rods is slidably connected to the support plate. A drive mechanism for driving one of the telescopic rods to slide along the support plate is installed on the support plate.

[0007] By adopting the above technical solution, one of the telescopic rods can slide on the support plate. When it is necessary to accommodate the bagging requirements of different sized packaging bags, the drive mechanism is activated to make one of the telescopic rods slide along the support plate. The sliding of the telescopic rod will drive the adjustment rod hinged to it to move. Since the two adjustment rods are hinged to each other and gradually tilt downwards in a direction that brings them closer together, the movement of the adjustment rod will change the distance between the two telescopic rods and the tilt angle of the adjustment rod, thereby adjusting the width of the support frame. Then, according to the needs, the length of each telescopic rod can be adjusted to adjust the height of the support frame to accommodate packaging bags of different sizes, facilitating the relatively neat assembly of composite bags of different sizes.

[0008] Preferably, the upper surface of the support plate is provided with a sliding groove, and a slider is fixedly connected to the lower end of one of the telescopic rods. The slider is slidably connected to the sliding groove. The driving mechanism includes a reciprocating screw rotatably connected in the sliding groove, and an adjustment component for driving the reciprocating screw to rotate is installed on the support plate.

[0009] By adopting the above technical solution, the groove on the upper surface of the support plate cooperates with the slider at the lower end of the telescopic rod, allowing one of the telescopic rods to slide on the support plate. The reciprocating screw in the drive mechanism rotates within the groove. When the adjusting component drives the reciprocating screw to rotate, the slider, in cooperation with the reciprocating screw, will reciprocate along the groove, thereby driving the connected telescopic rod to slide on the support plate, realizing the adjustment of the distance between the two telescopic rods to adapt to different bagging requirements.

[0010] Preferably, an adjusting plate is fixedly connected to one side wall of the support plate. The adjusting assembly includes a fixed rod fixedly connected to the adjusting plate, a rotating shaft rotatably connected to the fixed rod, an inclined foot pedal fixedly connected to one end of the rotating shaft, an adjusting spring fixedly connected between the foot pedal and the adjusting plate, and an adjusting disc fixedly connected to the other end of the rotating shaft. An adjusting groove is formed on the side wall of the adjusting disc opposite to the rotating shaft. A pawl is installed on the inner wall of the adjusting groove, and a ratchet that cooperates with the pawl is inserted into the adjusting groove. A connecting shaft is fixedly connected to the ratchet, and the connecting shaft is rotatably connected to the support plate. A bevel gear is coaxially fixed to the connecting shaft, and a bevel gear is also coaxially fixed to one end of the reciprocating screw. The two bevel gears mesh.

[0011] By adopting the above technical solution, when it is necessary to adjust the distance between the two telescopic rods, the operator steps on the foot pedal. The foot pedal rotates around the pivot and compresses the adjusting spring, which in turn drives the adjusting disc to rotate. The pawl in the adjusting disc pushes the ratchet to rotate, and the ratchet drives the connecting shaft to rotate. The bevel gear on the connecting shaft rotates accordingly. Through meshing with the bevel gear on the reciprocating screw, the reciprocating screw rotates, thereby driving the telescopic rod connected to the slider to slide in the groove, thus adjusting the position of the telescopic rod. When the foot pedal is released, the adjusting spring resets, causing the foot pedal to return to its initial position. Due to the cooperation between the pawl and the ratchet, the ratchet is difficult to reverse. By repeatedly stepping on the foot pedal, the distance between the two telescopic rods can be adjusted, thereby adjusting the width of the support frame. The operation is simple and convenient.

[0012] Preferably, the upper surface of the support plate is provided with a maintenance groove, one end of the reciprocating screw extends into the maintenance groove and is rotatably connected to the side wall of the maintenance groove, one end of the connecting shaft also extends into the maintenance groove, both bevel gears are placed in the maintenance groove, and a door is hinged at the opening of the maintenance groove to close the maintenance port.

[0013] By adopting the above technical solution, placing the reciprocating lead screw, one end of the connecting shaft, and the two bevel gears in the maintenance slot can prevent the two bevel gears from being exposed and damaged. At the same time, the hinged door at the opening of the maintenance slot can facilitate the maintenance operation of the bevel gears in the maintenance slot.

[0014] Preferably, each of the telescopic rods includes a sleeve and a rod arranged vertically, the sleeve and the rod being slidably inserted into each other, and a locking rod being threaded onto the sleeve, one end of the locking rod abutting against the side wall of the rod.

[0015] By adopting the above technical solution, the telescopic rod of the bagging support device adopts a structure in which the sleeve and the sleeve rod slide and insert into each other, and the length of the telescopic rod can be adjusted to adapt to different bagging needs; by using the locking rod to press against the side wall of the sleeve rod, the telescopic rod can be fixed at the required length, ensuring the stability of the support device during use.

[0016] Preferably, the outer side of the support frame is covered with a protective sleeve with an open bottom surface, the protective sleeve comprising two half-sleeves, and a plurality of elastic ropes are installed between the two half-sleeves.

[0017] By adopting the above technical solution, the protective sleeve covering the outside of the support frame can reduce the possibility of damage to the bag caused by the components on the support frame. The protective sleeve consists of two halves, with multiple elastic cords installed between the halves. When it is necessary to adjust the distance between the two telescopic rods, the elastic cords can stretch or contract according to the change in distance, ensuring that the protective sleeve can always adapt to the state of the support frame. At the same time, this elastic connection method allows the protective sleeve to stably wrap around the support frame at different distances between the telescopic rods, which is convenient, quick, and flexible to adapt to the adjustment of the distance between the telescopic rods.

[0018] Preferably, one end of each elastic rope is fixedly connected to the inner wall of one half of the set, and the inner wall of the other half of the set is fixedly connected to multiple hooks. Each elastic rope has multiple hanging openings distributed along the length of the elastic rope, and one hanging opening on each elastic rope is hooked to a corresponding hook.

[0019] By adopting the above technical solution, multiple hanging points on the elastic rope can be selected to be connected to different hanging points and hooks as needed, so as to adjust the tension of the protective sleeve to adapt to different widths of the support frame.

[0020] Preferably, the length of the protective sleeve is greater than the length of the sleeve tube.

[0021] By adopting the above technical solution, since the length of the protective sleeve is greater than the length of the sleeve, the locking rod can be completely covered inside the protective sleeve. This effectively reduces the occurrence of the locking rod directly contacting the bag during the bagging process, thereby reducing the possibility of the bag being torn. This improves the success rate and efficiency of bagging and reduces the cost of bag damage.

[0022] In summary, this application includes at least one of the following beneficial technical effects: Adjust the height and width of the support frame to accommodate packaging bags of different sizes, making it easier to assemble composite bags of different sizes in a more orderly manner; This facilitates the maintenance of the bevel gears inside the inspection slot; A protective cover placed on the outside of the support frame can reduce the possibility of damage to the bag caused by components on the support frame.

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a bagging support device. (Refer to...) Figure 1 and Figure 2 The bagging support device includes a support plate 1 and a support frame 2 fixed on the support plate 1. The support frame 2 is used to attach bags, so that multiple bags can be attached to each other to form a composite bag.

[0030] The support frame 2 includes two vertically arranged telescopic rods 21. One telescopic rod 21 is fixedly connected to the support plate 1, and the other telescopic rod 21 is slidably connected to the support plate 1. A drive mechanism 3 is installed on the support plate 1 to drive one of the telescopic rods 21 to slide along the support plate 1. Each telescopic rod 21 includes a sleeve 211 and a sleeve rod 212 arranged vertically, with the sleeve 211 and sleeve rod 212 slidably inserted into each other. A locking rod 213 is threadedly connected to the side wall of each sleeve 211, with one end of the locking rod 213 extending into the sleeve 211 and abutting against the side wall of the sleeve rod 212. This structure allows the length of the telescopic rod 21 to be adjusted according to actual needs.

[0031] When dealing with bags of different heights, the length of the telescopic rod 21 can be adjusted to form support frames 2 of different heights to accommodate the bags.

[0032] Reference Figure 1 and Figure 2 Each telescopic rod 21 has an adjusting rod 22 hinged to its upper end. Both adjusting rods 22 extend towards each other and are hinged together, and the two adjusting rods 22 gradually tilt downwards in the direction of approach. This structure allows the two adjusting rods 22 to form a scissor-like opening and closing action when the drive mechanism 3 adjusts the distance between the two telescopic rods 21, thereby supporting bags of different sizes.

[0033] The upper surface of the support plate 1 is provided with a sliding groove 11. The lower end of one of the telescopic rods 21 is fixedly connected to a slider 23. The slider 23 is a dovetail block, and the sliding groove 11 is a dovetail groove that matches the slider 23. The slider 23 is slidably connected to the sliding groove 11, so that the telescopic rod 21 can slide smoothly along the sliding groove 11.

[0034] The drive mechanism 3 includes a reciprocating screw 31 rotatably connected in the slide groove 11, the reciprocating screw 31 passes through the slider 23 and is threadedly connected to the slider 23, and an adjustment component 32 for driving the reciprocating screw 31 to rotate is installed on the support plate 1.

[0035] The start adjustment component 32 drives the reciprocating screw 31 to rotate. The rotation of the reciprocating screw 31 will cause the slider 23 that cooperates with the reciprocating screw 31 to slide in the slide groove 11, thereby realizing the movement of the telescopic rod 21 and adjusting the distance between the two telescopic rods 21 to adapt to bags of different widths.

[0036] An adjusting plate 4 is fixedly connected to one side wall of the support plate 1. The adjusting plate 4 is the same length as the support plate 1, but the upper surface of the adjusting plate 4 is lower than the upper surface of the support plate 1.

[0037] Reference Figure 1 and Figure 2The adjustment assembly 32 includes a fixed rod 321 fixedly connected to the adjustment plate 4. The fixed rod 321 is vertically arranged, and a rotating shaft 322 is rotatably connected to the upper end of the fixed rod 321. One end of the rotating shaft 322 is fixedly connected to an inclined foot pedal 323. An adjustment spring 324 is provided between the foot pedal 323 and the adjustment plate 4. One end of the adjustment spring 324 is fixedly connected to the foot pedal 323, and the other end is fixedly connected to the adjustment plate 4. A circular adjustment disc 325 is fixedly connected to the other end of the rotating shaft 322. An adjustment groove 3251 is opened on the side of the adjustment disc 325 away from the fixed rod 321, and a pawl 326 is installed on the inner wall of the adjustment groove 3251.

[0038] A maintenance groove 12 is provided on the upper surface of the support plate 1. One end of the reciprocating screw 31 extends into the maintenance groove 12 and is rotatably connected to one side wall of the maintenance groove 12. A bevel gear 327 is coaxially fixed on the reciprocating screw 31 and is placed in the maintenance groove 12. A connecting shaft 328 is also rotatably connected in the maintenance groove 12. One end of the connecting shaft 328 is also coaxially fixed with the bevel gear 327, and the other end extends towards the adjustment plate 325 and passes through the support plate 1. The two bevel gears 327 mesh with each other. A ratchet 329 is coaxially fixed at the end of the connecting shaft 328 near the adjustment plate 325. The ratchet 329 is inserted into the adjustment groove 3251 and engages with the pawl 326.

[0039] When the foot pedal 323 is pressed, the adjusting spring 324 is compressed. The foot pedal 323 rotates, causing the adjusting disc 325 to rotate via the rotating shaft 322. The rotating disc 325 then drives the ratchet 329 via the pawl 326. The ratchet 329, in turn, drives the reciprocating screw 31 via the connecting shaft 328 and two bevel gears 327, thereby moving the slider 23 and the corresponding telescopic rod 21. When the foot pedal 323 is released, it rotates back to its original position under the force of the adjusting spring 324. The foot pedal 323 then drives the adjusting disc 325 to rotate back to its original position via the rotating shaft 322, while the pawl 326 rotates in the opposite direction and cannot drive the ratchet 329. By repeatedly pressing the foot pedal 323, the distance between the two telescopic rods 21 can be adjusted. The reciprocating screw 31 is set so that there is no need to change the direction of rotation of the reciprocating screw 31. When the slider 23 moves to the limit position along the reciprocating screw 31, the slider 23 automatically moves in the opposite direction along the reciprocating screw 31.

[0040] The inspection slot 12 is hinged to a door 5 that closes the inspection port. The inspection slot 12 and door 5 facilitate the inspection and maintenance of internal components such as the bevel gear 327.

[0041] Reference Figure 3 and Figure 4The support frame 2 is covered by a protective sleeve 6 with an open bottom. The protective sleeve 6 is divided into two halves 61, each half corresponding to a telescopic rod 21. The half half 61 covers the outside of the telescopic rod 21, and multiple elastic ropes 7 are installed between the two halves 61. The protective sleeve 6 can reduce the possibility of the support frame 2 tearing the bag.

[0042] One end of each elastic cord 7 is fixedly connected to the inner wall of one half-case 61, and multiple hooks 8 are fixedly connected to the inner wall of the other half-case 61. Each elastic cord 7 has multiple hanging openings 71 distributed along the length of the elastic cord 7, and one hanging opening 71 on each elastic cord 7 is hooked to a corresponding hook 8. This connection method allows the protective sleeve 6 to be disassembled and installed as needed, and the tightness can be adjusted to accommodate different distances between the two telescopic rods 21. The length of the protective sleeve 6 is greater than the length of the sleeve 211, so that the locking rod 213 can be covered inside the protective sleeve 6, reducing the possibility of the locking rod 213 tearing the bag.

[0043] The implementation principle of the bag-filling support device in this embodiment is as follows: The bag-filling support device, through its adjustable telescopic rod 21 and adjusting rod 22, can flexibly adjust the width and height of the support frame 2 to adapt to the bag-filling needs of different bag sizes. The drive mechanism 3 adopts a foot-operated adjusting component 32, which is convenient to operate and reduces labor intensity. When assembling composite bags, the inner bag is fitted onto the support frame 2, and then the outer bag is fitted onto the inner bag. Simultaneously, the two bags are pulled away from the support frame 2, at which point the inner and outer bags are assembled.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
