Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, in particular to a conveying device and a packaging machine. Background Art

[0002] In the instant noodles industry, products are diversified, and they are mainly divided into two categories according to the packaging form: bag noodles and container noodles. Container noodles are subdivided into three types: cup noodles, bowl noodles, and square box noodles. The external dimensions are also different, so the equipment for sorting and packing container noodles is also diverse. For the same noodle factory, the transportation and accumulation of various container noodles requires the introduction of multiple production lines, resulting in a waste of space and manpower. Therefore, there is an urgent need for a conveying equipment and packaging machine that can accommodate the transportation needs of materials of multiple sizes and improve the adaptability range. Summary of the invention

[0003] In view of the above problems in the prior art, the present application provides a conveying device and a packaging machine to be compatible with the conveying requirements of materials of multiple sizes and to improve the adaptability range.

[0004] To achieve the above-mentioned purpose, the first aspect of the present application provides a conveying equipment, including: a first chain, the first chain is ring-shaped, and a load-bearing area and a window area are arranged on the first chain along the extension direction of the first chain, and the load-bearing area and the window area are alternately arranged; a load-bearing plate, the load-bearing plate is arranged in the load-bearing area and is fixedly connected to the first chain; a first baffle, the first baffle is located on the outside of the first chain, is fixedly arranged on the load-bearing plate, is located at a position close to one side of the load-bearing area, and is perpendicular to the extension direction of the first chain; a second chain, the second chain is parallel to the first chain; a second baffle, the second baffle is located on the outside of the first chain, is arranged at a position close to the other side of the load-bearing area, and is perpendicular to the extension direction of the second chain, and the second baffle passes through the window area and is fixedly connected to the second chain; wherein the load-bearing plate, the first baffle and the second baffle form a space for accommodating materials, and the first chain and the second chain can rotate synchronously or can be decoupled and rotated separately.

[0005] From the above, by making the first chain and the second chain rotate synchronously, the load-bearing plate, the first baffle and the second baffle can be driven to move synchronously, so that the material can be stably transported. When the size requirement of the material to be transported changes, the first chain and the second chain can be decoupled and rotated separately, so that the distance between the first baffle and the second baffle can be adjusted to meet the requirements of transporting materials of different sizes. In this way, the adaptability range of the conveying equipment can be improved.

[0006] As a possible implementation of the first aspect, the conveying equipment also includes: a first transmission shaft; a first sprocket, the first sprockets are arranged in pairs, the first chain is mounted on the paired first sprockets, and one of the paired first sprockets is fixedly mounted on the first transmission shaft; a second sprocket, the second sprockets are arranged in pairs, the second chain is mounted on the paired second sprockets, and one of the paired second sprockets is mounted on the first transmission shaft via a bearing; a second transmission shaft, the second transmission shaft is connected to the second sprocket and the first transmission shaft via gear transmission, and the gear on the second transmission shaft that is transmission-connected to the first transmission shaft is mounted on the second transmission shaft via a bearing; a connecting member, the connecting member is used to fix or decouple the gear on the second transmission shaft that is transmission-connected to the first transmission shaft and the second transmission shaft; a motor, the motor is transmission-connected to the first transmission shaft.

[0007] As described above, after the gear on the second transmission shaft that is transmission-connected to the first transmission shaft is fixedly connected to the second transmission shaft, the motor can drive the first sprocket fixed on the first transmission shaft to rotate through the gear transmission connection with the first transmission shaft, and at the same time, through the gear transmission between the first transmission shaft and the second transmission shaft, through the gear transmission between the second transmission shaft and the second sprocket, the second sprocket is driven to rotate. In this way, the synchronous rotation of the first sprocket and the second sprocket can be achieved, and then the synchronous rotation of the first chain and the second chain can be achieved. When the size requirements of material transportation change and the distance between the first baffle and the second baffle needs to be adjusted, the gear on the second transmission shaft that is transmission-connected to the first transmission shaft and the second transmission shaft can be decoupled through the connecting member, so that the gear on the second transmission shaft that is transmission-connected to the first transmission shaft can rotate freely on the second transmission shaft, so that the first transmission shaft and the second transmission shaft can be decoupled, and then the first chain and the second chain can be decoupled and rotated separately. In this way, the distance between the first baffle and the second baffle can be adjusted, so that the conveying equipment can adapt to the transportation requirements of materials of different sizes.

[0008] As a possible implementation of the first aspect, two first chains and two second chains are respectively provided, the two second chains are located between the two first chains, the two ends of the supporting plate are respectively fixedly connected to the two first chains, and the two second chains are respectively fixedly connected to the two sides of the second baffle.

[0009] As described above, by providing two first chains and two second chains respectively, the load-bearing plate, the first baffle plate and the second baffle plate can be fixed at both sides thereof, thereby improving the stability of the load-bearing plate, the first baffle plate and the second baffle plate.

[0010] As a possible implementation of the first aspect, the supporting plate includes a plurality of rectangular split plates, both ends of the split plates are respectively fixedly connected to the two first chains, the plurality of split plates are arranged along the extension direction of the first chains, and the first baffle is fixedly mounted on the split plate located at one end of the plurality of split plates.

[0011] As described above, by using a plurality of split plates to form a bearing plate, the bearing plate can be more flexible when the first chain bends at the first sprocket position.

[0012] As a possible implementation manner of the first aspect, a length of the split plate in an extending direction of the first chain is twice a pitch of the first chain.

[0013] As described above, by making the length of the split plate in the extension direction of the first chain twice the pitch of the first chain, the split plate can be supported by two or three links of the first chain when it is in a horizontal state. Thus, the stability of the split plate can be improved, and the stability of material transportation can be improved.

[0014] As a possible implementation manner of the first aspect, the conveying equipment also includes a first track, which is located at an inner side of the first chain, extends in a horizontal direction, and abuts against a portion above the first chain.

[0015] From the above, by setting the first track, the first track can support the first chain below the first chain to prevent the first chain from bending downward under the action of gravity. In this way, the upper part of the first chain can be kept horizontal, and the bearing plate and the first baffle on the first chain and the material can be kept stationary. In this way, not only can the stability of material transportation be improved, but also friction between the bearing plate, the first baffle and the material can be avoided, which can cause wear to the material.

[0016] As a possible implementation of the first aspect, the conveying equipment also includes: a second track, which is located at the inner side of the second chain, extends in the horizontal direction, and is located at a corresponding position below the part above the second chain; a third track, which is located at the outer side of the second chain, extends in the horizontal direction, and is located at a corresponding position above the part above the second chain, and the part above the second chain is clamped between the second track and the third track.

[0017] From the above, by setting the second track and the third track, the upper part of the second chain is sandwiched between the second track and the third track, so that the second chain can be restricted so that the upper part of the second chain cannot bend upward or downward. In this way, the upper part of the second chain can be kept horizontal, and the second baffle on the second chain and the material can be kept stationary. In this way, not only the stability of material transportation can be improved, but also friction between the second baffle and the material can be avoided, which can prevent the material from being worn.

[0018] As a possible implementation of the first aspect, the conveying equipment also includes: a frame, on which the first sprocket and the second sprocket are mounted; and an adjusting member, which is mounted on the frame to adjust the distance between the pairs of the first sprockets and / or adjust the distance between the pairs of the second sprockets.

[0019] As a possible implementation of the first aspect, the adjusting member is a screw, which is threadedly connected to the other of the pair of first sprockets to drive the other of the first sprockets to move along the extension direction of the first sprocket; and / or, is threadedly connected to the other of the pair of second sprockets to drive the other of the second sprockets to move along the extension direction of the second sprocket.

[0020] As described above, the distance between the paired first sprocket and the second sprocket is adjusted by the adjusting member, so that the tension of the first chain and the second chain sleeved on the first sprocket and the second sprocket can be adjusted, so that the first sprocket and the second sprocket between the paired first sprocket and the second sprocket remain horizontal. Thus, the stability of conveying materials can be improved.

[0021] A second aspect of the present application provides a packaging machine, comprising the conveying device described in any one of the first aspects of the present application.

[0022] As described above, by making the first chain and the second chain rotate synchronously, the load-bearing plate, the first baffle and the second baffle can be driven to move synchronously, so that the material can be stably conveyed. When the size requirement of the material conveying changes, the first chain and the second chain can be decoupled and rotated separately, so that the distance between the first baffle and the second baffle can be adjusted to meet the conveying requirements of materials of different sizes. In this way, the adaptability range of the packaging machine can be improved.

[0037] Below, in conjunction with the accompanying drawings, possible embodiments of the conveying device 10 in the present application are exemplarily described.

[0038] The conveying device 10 in the present application includes a first chain 210, a bearing plate 230, a first baffle 240, a second chain 310 and a second baffle 330. The first chain 210 is ring-shaped, and a bearing area 250 and a window area 260 are arranged on the first chain 210 along the extension direction of the first chain 210, and the bearing area 250 and the window area 260 are arranged alternately. The bearing plate 230 is arranged in the bearing area 250 and is fixedly connected to the first chain 210. The first baffle 240 is located on the outside of the first chain 210, fixedly arranged on the bearing plate 230, and is located near one side of the bearing area 250, and is perpendicular to the extension direction of the first chain 210. The second chain 310 is parallel to the first chain 210, the second baffle 330 is located outside the first chain 210, and is arranged at a position close to the other side of the bearing area 250, perpendicular to the extension direction of the second chain 310, and the second baffle 330 passes through the empty window area 260 and is fixedly connected to the second chain 310. The bearing plate 230, the first baffle 240 and the second baffle 330 form a space for accommodating materials, and the first chain 210 and the second chain 310 can rotate synchronously, or can be decoupled and rotated separately.

[0039] As described above, by making the first chain 210 and the second chain 310 rotate synchronously, the bearing plate 230, the first baffle 240 and the second baffle 330 can be driven to move synchronously, so that the material can be stably transported. When the size requirement of the material to be transported changes, the first chain 210 and the second chain 310 can be decoupled and rotated separately, so that the distance between the first baffle and the second baffle 330 can be adjusted to meet the requirements of transporting materials of different sizes. In this way, the adaptability range of the conveying device 10 can be improved.

[0040] In some embodiments, the conveying device 10 further includes a first transmission shaft 420, a first sprocket 220, a second sprocket 320, a second transmission shaft 430, a connecting member and a motor 410. The first sprockets 220 are arranged in pairs, the first chains 210 are sleeved on the paired first sprockets 220, and one of the paired first sprockets 220 is fixedly mounted on the first transmission shaft 420. The second sprockets 320 are arranged in pairs, the second chains 310 are sleeved on the paired second sprockets 320, and one of the paired second sprockets 320 is mounted on the first transmission shaft 420 through a bearing. The second transmission shaft 430 is connected to the second sprocket 320 and the first transmission shaft 420 through a gear transmission, and the gear on the second transmission shaft 430 that is transmission-connected to the first transmission shaft 420 is installed on the second transmission shaft 430 through a bearing. The connecting member is used to make the gear on the second transmission shaft 430 that is transmission-connected to the first transmission shaft 420 fixedly connected to or decoupled from the second transmission shaft 430. The motor 410 is transmission-connected to the first transmission shaft 420.

[0041] As described above, after the gear on the second transmission shaft 430 that is transmission-connected to the first transmission shaft 420 is fixedly connected to the second transmission shaft 430, the motor 410 can drive the first sprocket 220 fixed on the first transmission shaft 420 to rotate through the gear transmission connection with the first transmission shaft 420, and at the same time, through the gear transmission between the first transmission shaft 420 and the second transmission shaft 430, and through the gear transmission between the second transmission shaft 430 and the second sprocket 320, the second sprocket 320 is driven to rotate. In this way, the synchronous rotation of the first sprocket 220 and the second sprocket 320 can be achieved, and then the synchronous rotation of the first chain 210 and the second chain 310 can be achieved. When the size requirement of material conveying changes and the distance between the first baffle 240 and the second baffle 330 needs to be adjusted, the gear on the second transmission shaft 430 that is transmission-connected to the first transmission shaft 420 can be decoupled from the second transmission shaft 430 through a connecting piece, so that the gear on the second transmission shaft 430 that is transmission-connected to the first transmission shaft 420 can rotate freely on the second transmission shaft 430, thereby decoupling the first transmission shaft 420 from the second transmission shaft 430, and further decoupling the first chain 210 from the second chain 310 to rotate independently. In this way, the distance between the first baffle 240 and the second baffle 330 can be adjusted, so that the conveying device 10 can adapt to the conveying requirements of materials of different sizes.

[0042] In some embodiments, the conveying device 10 further includes a first transmission shaft 420, a first sprocket 220, a second sprocket 320, a connecting member and a motor 410. The first sprockets 220 are arranged in pairs, the first chains 210 are sleeved on the paired first sprockets 220, and one of the paired first sprockets 220 is fixedly mounted on the first transmission shaft 420. The second sprockets 320 are arranged in pairs, the second chains 310 are sleeved on the paired second sprockets 320, and one of the paired second sprockets 320 is mounted on the first transmission shaft 420 through a bearing. The connecting member is used to fix the second sprocket 320 to the first transmission shaft 420. The motor 410 is in transmission connection with the first transmission shaft 420.

[0043] As described above, when the second sprocket 320 is fixedly connected to the first transmission shaft 420 through a connecting piece, the motor 410 can drive the first sprocket 220 and the second sprocket 320 on the first transmission shaft 420 to rotate synchronously through a gear transmission connection with the first transmission shaft 420. When the size requirements of material transportation change and the distance between the first baffle 240 and the second baffle 330 needs to be adjusted, the second sprocket 320 can be loosened from the first transmission shaft 420 by removing or loosening the connecting piece, and can rotate freely on the first transmission shaft 420, so that the first transmission shaft 420 and the second sprocket 320 can be decoupled, and then the first chain 210 and the second chain 310 can be decoupled and rotated separately. In this way, the distance between the first baffle 240 and the second baffle 330 can be adjusted, so that the conveying device 10 can adapt to the transportation requirements of materials of different sizes.

[0044] In some embodiments, two first chains 210 and two second chains 310 are respectively provided, and the two second chains 310 are located between the two first chains 210, and the two ends of the bearing plate 230 are respectively fixedly connected to the two first chains 210, and the two second chains 310 are respectively fixedly connected to the two sides of the second baffle 330. Specifically, the first chain 210 and the second chain 310 have the same size, and the two first chains 210 and the two second chains 310 are respectively provided on four vertical planes parallel to each other, and the first chain 210 and the second chain 310 are parallel on the plane perpendicular to the first chain 210 and the second chain 310. Therefore, by providing two first chains 210 and two second chains 310 respectively, the bearing plate 230, the first baffle 240 and the second baffle 330 can be fixed at the two sides of the bearing plate 230, the first baffle 240 and the second baffle 330. Therefore, the stability of the bearing plate 230, the first baffle 240 and the second baffle 330 can be improved.

[0045] In some embodiments, the carrier plate 230 includes a plurality of rectangular split plates 231, the two ends of the split plates 231 are respectively fixedly connected to the two first chains 210, the plurality of split plates 231 are arranged along the extension direction of the first chain 210, and the first baffle 240 is fixedly mounted on a split plate 231 located at one end of the plurality of split plates 231. Thus, by using a plurality of split plates 231 to form the carrier plate 230, the carrier plate 230 can be more flexible when it bends with the first chain 210 at the first sprocket 220 position.

[0046] In some embodiments, the length of the split plate 231 in the extension direction of the first chain 210 is twice the pitch of the first chain 210. Thus, by making the length of the split plate 231 in the extension direction of the first chain 210 twice the pitch of the first chain 210, when the split plate 231 is in a horizontal state, two or three links of the first chain 210 can provide support for the split plate 231. In this way, the stability of the split plate 231 can be improved, thereby improving the stability of material transportation.

[0047] In some embodiments, the conveying device 10 further includes a first track 130, which is located inside the first chain 210, extends in the horizontal direction, and abuts against the upper portion of the first chain 210. Thus, by providing the first track 130, the first track 130 can support the first chain 210 below the first chain 210, thereby preventing the first chain 210 from bending downward under the action of gravity. Thus, the upper portion of the first chain 210 can be kept horizontal, thereby keeping the bearing plate 230 and the first baffle 240 on the first chain 210 stationary with the material. Thus, not only can the stability of the material conveying be improved, but also the friction between the bearing plate 230, the first baffle 240 and the material can be avoided, thereby preventing the material from being worn.

[0048] In some embodiments, the conveying device 10 further includes a second track 140 and a third track 150. The second track 140 is located at the inner side of the second chain 310, extends in the horizontal direction, and is located at a corresponding position below the upper part of the second chain 310. The third track 150 is located at the outer side of the second chain 310, extends in the horizontal direction, and is located at a corresponding position above the upper part of the second chain 310, and the upper part of the second chain 310 is sandwiched between the second track 140 and the third track 150. Thus, by setting the second track 140 and the third track 150, the upper part of the second chain 310 is sandwiched between the second track 140 and the third track 150, so that the second chain 310 can be restricted, so that the upper part of the second chain 310 cannot be bent upward or downward. Thus, the upper part of the second chain 310 can be kept horizontal, so that the second baffle 330 on the second chain 310 and the material remain stationary. Therefore, not only the stability of material transportation can be improved, but also the friction between the second baffle 330 and the material can be avoided, thereby preventing the material from being worn.

[0049] In some embodiments, the conveying device 10 further includes a frame 100 and an adjusting member 120. The first sprocket 220 and the second sprocket 320 are mounted on the frame 100, and the adjusting member 120 is mounted on the frame 100 to adjust the distance between the paired first sprockets 220 and / or the distance between the paired second sprockets 320.

[0050] In some embodiments, the adjusting member 120 is a screw, which is threadedly connected to the other of the paired first sprockets 220 to drive the other of the first sprockets 220 to move along the extension direction of the first sprocket 220; and / or is threadedly connected to the other of the paired second sprockets 320 to drive the other of the second sprockets 320 to move along the extension direction of the second sprocket 320. Thus, the distance between the paired first sprockets 220 and the second sprocket 320 can be adjusted by the adjusting member 120, so that the tension of the first chain 210 and the second chain 310 sleeved on the first sprocket 220 and the second sprocket 320 can be adjusted, so that the first sprocket 220 and the second sprocket 320 between the paired first sprockets 220 and the second sprocket 320 remain horizontal. Thus, the stability of the material during conveying can be improved.

[0051] The above content is an exemplary description of possible embodiments of the conveying device 10. The present application also provides a packaging machine, which includes the conveying device 10. The conveying device 10 can be any possible implementation form of the conveying device 10 described above in the present application, which will not be described in detail.

[0052] In the following, the specific structure of the conveying device 10 in the present application is described in detail in a specific embodiment.

[0054] like Figure 1-Figure 3 As shown, the conveying device 10 includes a frame 100, a conveying mechanism 200, an adjusting mechanism 300 and a driving mechanism 400. The conveying mechanism 200, the adjusting mechanism 300 and the driving mechanism 400 are installed on the frame 100. The conveying mechanism 200 is used to provide a space for accommodating materials and to transport the materials. The adjusting mechanism 300 can transport the materials together with the conveying mechanism 200, and can also adjust the size of the space for accommodating the materials. The driving mechanism 400 is used to drive the conveying mechanism 200 and the adjusting mechanism 300 to move.

[0055] like Figure 3-Figure 5As shown, the conveying mechanism 200 includes a first chain 210, a first sprocket 220, a bearing plate 230 and a first baffle 240. The first sprockets 220 are arranged in pairs, and the two first sprockets 220 in a pair are arranged in the horizontal direction on the same vertical plane. The first chain 210 is annular and is sleeved on the two first sprockets 220 arranged in pairs. Two first chains 210 are arranged, and correspondingly, two pairs of first sprockets 220 are arranged. The two first chains 210 are parallel and at the same height. The first chain 210 is provided with a bearing area 250 and a window area 260, and the bearing area 250 and the window area 260 are alternately arranged. The bearing area 250 is used to carry materials, and the window area 260 is used to provide a movable space for the adjustment mechanism 300 during adjustment.

[0056] like Figure 4 , Figure 5 As shown, the carrying plate 230 includes a plurality of rectangular split plates 231, both ends of which are fixedly connected to the two first chains 210, and the plurality of split plates 231 are arranged along the extension direction of the first chains 210, forming a rectangular carrying area 250 on the first chains 210. The first baffle 240 is fixedly mounted on a split plate 231 located at one end of the plurality of split plates 231, so as to limit the material on the carrying plate 230 at this position.

[0057] like Figure 5 , Figure 6 As shown, the length of the split plate 231 in the extension direction of the first chain 210 is twice the pitch of the first chain 210. After installation, when viewed from the side, a link of the first chain 210 is located in the middle position below the split plate 231, and is used to support the middle 1 / 2 area of ​​the split plate 231. The 1 / 4 areas of the split plate 231 on both sides of the link are supported by the links connected at both ends of the link. In this way, the links of the three first chains 210 can provide support for each split plate 231. In this way, the stability of the split plate 231 can be improved, and the stability of material transportation can be improved.

[0058] like Figure 3-Figure 5As shown, the adjustment mechanism 300 includes a second chain 310, a second sprocket 320 and a second baffle 330. The second sprockets 320 are arranged in pairs, and the two second sprockets 320 in a pair are arranged in the horizontal direction on the same vertical plane. The second chain 310 is annular and is sleeved on the two second sprockets 320 arranged in pairs. There are two second chains 310, and correspondingly, there are two pairs of second sprockets 320. The second chain 310 is parallel to the first chain 210, located between the two first chains 210, and at the same height as the first chain 210. The second baffle 330 is arranged at a side of the bearing area 250 away from the first baffle 240, above the bearing plate 230, and is separated from the bearing plate 230. A connecting portion 331 is respectively arranged at the corresponding position of the two second chains 310 at the lower position of the second baffle 330, and the connecting portion 331 extends in a direction away from the first baffle 240 and then bends downward to be fixedly connected to the second chain 310. At the same time, by making the connecting portion 331 of the second baffle plate 330 be bent, an adjustment space can be provided for the second baffle plate 330 when the position of the second baffle plate 330 is adjusted as described below, so that the second baffle plate 330 can move above the supporting plate 230 .

[0059] like Figure 4 , Figure 5 As shown, after the load-bearing plate 230 carries the material, the first baffle 240 and the second baffle 330 limit the material in the front-rear direction of the first chain 210 and the second chain 310, that is, the load-bearing plate 230, the first baffle 240 and the second baffle 330 together form a space for accommodating the material. When the material needs to be transported, by placing the material on the load-bearing plate 230 and then driving the first chain 210 and the second chain 310 to rotate synchronously, the load-bearing plate 230, the first baffle 240 and the second baffle 330 can be kept stationary, so that the material can be stably transported under the joint protection of the load-bearing plate 230, the first baffle 240 and the second baffle 330. When the size requirement of the material transportation changes, the first chain 210 or the second chain 310 can be rotated separately to change the distance between the first baffle 240 and the second baffle 330 to adapt to the new size requirement of the material transportation.

[0060] like Figure 3As shown, the driving mechanism 400 includes a motor 410, a first transmission shaft 420 and a second transmission shaft 430. The motor 410 and the first transmission shaft 420 are driven by a chain, so that the motor 410 can drive the first transmission shaft 420 to rotate. The first sprocket 220 is fixedly arranged on the first transmission shaft 420, so that the first sprocket 220 and the first chain 210 on the first sprocket 220 can be driven to rotate by the motor 410. Two first gears 421 are arranged on the first transmission shaft 420, and the two first gears 421 are fixedly connected to the two second sprockets 320 respectively. The first gear 421 and the first sprocket 220 are installed on the first transmission shaft 420 through a bearing, so that the second sprocket 320 and the first sprocket 220 can be decoupled.

[0061] The second transmission shaft 430 is arranged in parallel with the first transmission shaft 420, and two second gears 431 are fixedly arranged on the second transmission shaft 430, and the two second gears 431 are respectively meshed with the two first gears 421. The second transmission shaft 430 is also provided with a third gear 432 and a flange 433 (connector) at a position close to one end of the motor 410, and the third gear 432 is installed on the second transmission shaft 430 through a bearing, and the flange 433 is fixed on the second transmission shaft 430, and is located close to the third gear 432. The flange 433 can be fixedly connected to the third gear 432 by screws, so that the third gear 432 can be fixedly connected to the second transmission shaft 430. The flange 433 can also be decoupled from the third gear 432 by removing the screws, that is, the fixed connection relationship is released, so that the third gear 432 can rotate freely on the second transmission shaft 430, thereby decoupling the first sprocket 220 from the second sprocket 320.

[0062] The first transmission shaft 420 is also fixedly provided with a fourth gear 422, which meshes with the third gear 432. Thus, when conveying materials, the flange 433 can be fixedly connected with the third gear 432, so that the motor 410 can synchronously drive the first sprocket 220 and the second sprocket 320 to rotate. When it is necessary to adjust the distance between the first baffle 240 and the second baffle 330, the flange 433 can be decoupled from the third gear 432, so that the first sprocket 220 and the second sprocket 320 can be decoupled, so that the first sprocket 220 or the second sprocket 320 can be driven to rotate separately, and the distance between the first baffle 240 and the second baffle 330 can be adjusted. In addition, by adopting the above structure, the synchronous rotation or decoupling control between the two first sprockets 220 and the two second sprockets 320 can be realized through a flange 433, so that the difficulty of operation during the adjustment operation can be reduced.

[0063] Figure 6 for Figure 3 FIG. 1 is a schematic diagram showing the side connection between the first sprocket 220 and the frame 100. Figure 3 , Figure 6 As shown, the other of the paired first sprockets 220 is fixedly mounted on the frame 100. Specifically, the frame 100 is provided with a rectangular through-hole-shaped mounting hole 110 at a position corresponding to the rotating shaft of the first sprocket 220. The mounting hole 110 extends along the extending direction of the first chain 210. The rotating shaft of the first sprocket 220 is located in the mounting hole 110 and can move along the extending direction of the mounting hole 110. The frame 100 is also provided with an adjusting member 120. The adjusting member 120 is in the shape of a screw and can pass through the frame 100 and extend into the mounting hole 110 along the extending direction of the mounting hole 110. The adjusting member 120 is mounted on the frame 100 and is rotatably connected to the frame 100, that is, it can rotate on the frame 100, but cannot move in other directions. The adjusting member 120 is threadedly connected to the rotating shaft of the first sprocket 220, so that the first sprocket 220 can be driven to move in the mounting hole 110 by rotating the adjusting member 120. Thus, the two first sprockets 220 in a pair can be moved closer or farther away, thereby adjusting the tension of the first chain 210 so that the first chain 210 between the two first sprockets 220 in a pair remains horizontal. Figure 3 As can be seen from the illustrated content, the installation structure of the second sprocket 320 is the same as the installation structure of the first sprocket 220, so it will not be described again here.

[0064] Figure 7 FIG. 2 is a schematic diagram of the connection structure between the first chain 210 and the second chain 310. Figure 7 As shown, the frame 100 is provided with a first track 130, which is located at the inner side of the first chain 210, extends in the horizontal direction, and abuts against the upper part of the first chain 210 between the two paired first sprockets 220. Specifically, the first track 130 abuts against the roller of the first chain 210, supports the first chain 210 below the first chain 210, and prevents the first chain 210 from bending downward under the action of gravity, so that the first chain 210 and the bearing plate 230 installed on the first chain 210 are kept horizontal, and the first baffle 240 on the bearing plate 230 is kept in a vertical state. In this way, it can be avoided that the film packaging on the material is worn due to the bending of the bearing plate 230 and the shaking of the first baffle 240 when conveying the material.

[0065] like Figure 7As shown, the frame 100 is also provided with a second track 140 and a third track 150. The second track 140 is located at the inner side of the second chain 310, extending in the horizontal direction, and located at a corresponding position below the portion above the second chain 310 between the two second sprockets 320. The third track 150 is located at the outer side of the second chain 310, extending in the horizontal direction, and located at a corresponding position above the portion above the second chain 310 between the two second sprockets 320, and the portion above the second chain 310 is sandwiched between the second track 140 and the third track 150. The connecting portion 331 of the second baffle 330 is fixedly connected to the pin on the second chain 310. Since the second connecting portion 331 is bent, there is an offset between the center of gravity of the two and the position of the installed pin, so that the second baffle 330 will drive the second chain 310 to have a downward flipping trend under the action of gravity. By setting the second rail 140 and the third rail 150, the upper part of the second chain 310 is sandwiched in the middle by the second rail 140 and the third rail 150, and specifically, the roller of the first chain 210 is sandwiched in the middle, so that the second chain 310 can be restricted so that the upper part of the second chain 310 cannot bend upward or downward. In this way, the upper part of the second chain 310 can be kept horizontal, so that the stability of the second baffle 330 when conveying materials can be improved, thereby improving the stability of conveying materials.

[0066] Furthermore, the surfaces of the carrier plate 230, the first baffle plate 240, and the second baffle plate 330 are treated with Teflon. Teflon high-performance special coating is a fluorine coating with polytetrafluoroethylene as the base resin. The English name is Teflon. Teflon coating is a unique high-performance coating that combines heat resistance, chemical inertness, excellent insulation stability and low friction. It has comprehensive advantages that other coatings cannot compete with. Its flexibility of application enables it to be used on products of almost all shapes and sizes. In this way, the damage of the PE heat shrink film on the outside of the material can be reduced.

[0067] Furthermore, the first rail 130 , the second rail 140 and the third rail 150 are made of wear-resistant high-molecular polyethylene, thereby reducing the friction between the first chain 210 and the second chain 310 and increasing the service life of the first rail 130 , the second rail 140 and the third rail 150 .
