Description

Technical Field

[0001] This application relates to the technical field of wet wipe production equipment, and in particular to a belt telescopic material conveying device. Background Technology

[0002] Wet wipes are a common household item. During production, the material on the roll is first unfolded. After unfolding, the material passes through a folding device to fold it, ensuring each wipe is pressed against the previous one, making it easy for the user to remove from the packaging. The folded material then enters a humidifying device to humidify the wipes. After humidification, the wipes are cut to the required length by a cutting component. Finally, a roller conveyor transports the wipes to a packaging machine for packaging, resulting in the final product.

[0003] In existing technology, after being cut and shaped, the material enters the packaging machine at a constant speed via a roller conveyor. The material needs to be packed one package at a time on the roller conveyor, and the material slowly enters the packaging machine through the friction between the material and the rollers. Due to the small contact area between the rollers and the material, and the requirement for the packages to be packed one to one, adjacent packages are prone to arching during transport, especially when the material is thin. In addition, during the transport process, staff randomly pick up materials from the roller conveyor for inspection, which increases the distance between adjacent materials. As a result, when the material enters the packaging machine, the corresponding packaging bag may be empty, resulting in an empty bag. When the detection device detects an empty bag, the entire packaging machine will stop, causing instability in the operation of the equipment. On the one hand, manual removal is required afterward, affecting work efficiency; on the other hand, when an empty bag is detected, the corresponding packaging bag cannot be used, resulting in a waste of resources. Summary of the Invention

[0004] In order to reduce the occurrence of empty packages and improve work efficiency, this application provides a belt telescopic material conveying device.

[0005] The technical solution of the belt telescopic material conveyor provided in this application is as follows:

[0006] A belt telescopic material conveying device includes a frame and a conveying device mounted on the frame for conveying materials. The conveying device includes a first conveying component and a second conveying component, wherein the conveying speed of the first conveying component is greater than the conveying speed of the second conveying component.

[0007] The frame is provided with a first mounting frame and a second mounting frame that are slidably connected. The first mounting frame and the second mounting frame are arranged at a distance in the vertical direction. One end of the first conveying component is arranged on the first mounting frame and the other end is arranged on the second mounting frame. One end of the second conveying component is arranged on the first mounting frame and the other end is arranged on the second mounting frame.

[0008] The frame is provided with a drive assembly for driving the first mounting bracket and the second mounting bracket to move in opposite directions in the horizontal direction.

[0009] The first mounting frame is provided with a detection element, which is used to detect the time it takes for the material on the first conveying component to be transferred to the second conveying component. The frame is provided with a control element for connecting to the detection element. The control end of the control element is connected to the drive component and is used to control the operation of the drive component.

[0010] By adopting the above technical solution, the humidified material enters the first conveying component and is evenly spaced on it. Then, under the action of the first conveying component, the material is conveyed to the second conveying component. Since the speed of the second conveying component is lower than that of the first, the material conveyed to the second conveying component will stick together, facilitating packaging by the packaging machine. When a package is removed from the first conveying component, the distance between adjacent packages increases. When the material is transported to the second conveying component, the detector detects that no material has passed the detector within the same time frame. The detector then sends a signal to the control component, causing the control component to control the drive component. The drive component then moves the first mounting frame closer to the material on the first conveying component, while the second mounting frame moves in the opposite direction, reducing the distance between the material on the first conveying component and the detector and the second conveying component. This ensures that the material transported to the second conveyor belt remains tightly packed, reducing the occurrence of empty packages and improving the stability of the entire device.

[0011] Optionally, the first conveying assembly includes a first support roller rotatably connected to a first mounting frame, a second support roller rotatably connected to a second mounting frame, a first drive roller rotatably connected to a frame, and a first conveyor belt wound around the first support roller, the second support roller, and the first drive roller. The frame is provided with a first drive member for driving the first drive roller to rotate the first conveyor belt, and the frame is provided with a first limiting roller abutting against the first conveyor belt, so that the first conveying assembly is C-shaped.

[0012] The second conveying assembly includes a third support roller rotatably connected to the first mounting frame, a fourth support roller rotatably connected to the second mounting frame, a second drive roller rotatably connected to the frame, and a second conveyor belt wound around the third support roller, the fourth support roller, and the second drive roller. The frame is provided with a second drive member for driving the second drive roller to rotate the second conveyor belt. The frame is also provided with a second limiting roller that abuts against the second conveyor belt, making the second conveying assembly C-shaped.

[0013] By adopting the above technical solution, since both the first conveying component and the second conveying component are C-shaped and can rotate, the movement of the first mounting frame and the second mounting frame will not affect the material conveying on the first conveyor belt and the second conveyor belt. In addition, when the distance between adjacent materials changes, the detection element can be set to make the second conveyor belt follow the material on the first conveyor belt. Thus, during the conveying process, the material spacing on the second conveyor belt is very small, thereby reducing the occurrence of adjacent materials arching on the second conveyor belt and improving the stability during packaging.

[0014] Optionally, the drive assembly includes two rotating rollers rotatably connected to the frame, a synchronous toothed belt wound around the two rotating rollers, and a third drive component for driving the rotating rollers to rotate. Both the first mounting frame and the second mounting frame are provided with fixing components, and the first mounting frame and the second mounting frame are respectively fixed to the synchronous toothed belt by the fixing components.

[0015] By adopting the above technical solution, when it is necessary to move the first mounting bracket and the second mounting bracket, the third driving component works to drive the synchronous toothed belt to rotate, thereby causing the first mounting bracket and the second mounting bracket to move in opposite directions, which makes it more convenient to use.

[0016] Optionally, the fixing assembly includes a first clamping plate fixed to the first mounting bracket, a second clamping plate slidably connected to the first mounting bracket, and bolts passing through the first clamping plate, the second clamping plate, and the synchronous toothed belt, wherein the first clamping plate and the second clamping plate are located on opposite sides of the synchronous toothed belt.

[0017] By adopting the above technical solution, during installation, the first clamping plate and the second clamping plate are placed on opposite sides of the synchronous toothed belt, and bolts are sequentially passed through the first clamping plate, the second clamping plate, and the synchronous toothed belt, thereby achieving the fixation of the first mounting bracket and the second mounting bracket.

[0018] Optionally, the frame has two limiting grooves, which are formed along the rotation direction of the synchronous toothed belt. Limiting plates are fixedly installed on both the first mounting frame and the second mounting frame, and the two limiting plates are slidably connected in the two limiting grooves respectively.

[0019] By adopting the above technical solution, the first and second mounting brackets can be made more stable when moving under the action of the limiting groove and the limiting plate.

[0020] Optionally, an adjusting roller is slidably connected to the mounting frame, a first conveyor belt is wound around the adjusting roller, and a screw is rotatably connected to the adjusting roller. The axis of the screw is perpendicular to the axis of the adjusting roller, and the screw is threadedly connected to the frame.

[0021] By adopting the above technical solution, the position of the adjusting roller can be adjusted by rotating the screw under the action of the bolt, thereby fine-tuning the tension of the first conveyor belt. On the other hand, it is convenient to remove the adjusting roller from the frame.

[0022] Optionally, the frame is provided with two tension rollers, which abut against the first conveyor belt and the second conveyor belt respectively. The tension rollers are provided with adjusting components for adjusting the position of the tension rollers.

[0023] By adopting the above technical solution, the tension of the first and second conveyor belts is increased under the action of the tension roller. When it is necessary to remove the first or second conveyor belt, the position of the tension roller is adjusted to loosen the first or second conveyor belt, thereby facilitating the installation and replacement of the first or second conveyor belt and achieving tool-free disassembly.

[0024] Optionally, the detection element is configured as a material detection sensor for detecting the conveying time, the material detection sensor is disposed between the first support roller and the third support roller, and the control element is configured as a controller, the controller is connected to the material detection sensor, and the controller is also connected to the third drive element.

[0025] By adopting the above technical solution, when a package of material is conveyed to the second conveyor belt, the material detection sensor starts to detect it. When it detects that the next stack of material has not been conveyed to the second conveyor belt within a specified time, it sends a signal to the controller, which drives the third drive unit to work, thus making it more convenient to use.

[0026] Optionally, the frame is provided with two baffles, the first conveying assembly and the second conveying assembly are disposed between the two baffles, and the baffles are detachably connected with side plates by bolts, the side plates and the frame are disposed on opposite sides of the baffles.

[0027] By adopting the above technical solution, when the entire equipment needs to be repaired, the bolts and baffles on the side plate can be separated directly, and the side plate can be removed directly to repair the parts between the two baffles. This makes it more convenient to use and maintain the equipment, achieving the effect of tool-free disassembly.

[0028] Optionally, the side panel is provided with multiple handles.

[0029] By adopting the above technical solution, when the bolts and baffle on the side plate are separated, the side plate can be directly removed by the handle, thereby achieving the purpose of conveniently taking the side plate by the action of the handle. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] This application discloses a belt telescopic material conveyor. (Refer to...) Figure 1A belt telescopic material conveying device includes a frame 1, which is horizontally set on the ground, and a conveying device 2 for conveying material movement is provided on the frame 1. In this embodiment, the material is set as stacked wet wipes, and the conveying device 2 is used to convey the wet wipes into the packaging machine.

[0040] Reference Figure 1 and Figure 2 The conveying device 2 includes a first conveying component 3 and a second conveying component 4. The second conveying component 4 and the first conveying component 3 are symmetrically arranged, and the conveying speed of the first conveying component 3 is greater than the conveying speed of the second conveying component 4. Thus, when conveying materials, the materials conveyed to the second conveying component 4 can be tightly packed together, which facilitates packaging by the packaging machine.

[0041] Reference Figure 2 and Figure 3 The first conveying assembly 3 encapsulates the first support roller 31, the second support roller 32, the first limiting roller 33, the first drive roller 34, and the first conveyor belt 35. The first conveyor belt 35 is wound around the first support roller 31, the second support roller 32, and the first drive roller 34. The first limiting roller 33 and the first drive roller 34 are rotatably connected to the frame 1. Simultaneously, the first limiting roller 33 abuts against the first conveyor belt 35, causing the first conveyor belt 35 to bulge away from the second conveying assembly 4, thus giving the first conveyor belt 35 a C-shaped structure, with the opening of the first conveyor belt 35 facing the second conveying assembly 4. The first support roller 31 and the second support roller 32 are vertically spaced apart, and the first support roller 31 is provided with a first mounting frame 11. The first support roller 31 is rotatably connected to the first mounting frame 11, and the first mounting frame 11 is slidably connected to the frame 1. Simultaneously, combined with... Figure 4 A drive assembly 5 is provided on the frame 1, which is used to drive the first mounting bracket 11 to slide on the frame 1; (review) Figure 2 and Figure 3 A second mounting bracket 12 is provided on the second support roller 32. The second mounting bracket 12 is slidably connected to the frame 1, and the second support roller 32 rotates on the second mounting bracket 12. Figure 4 The drive assembly 5 also drives the second mounting bracket 12 to slide on the frame 1, and causes the first mounting bracket 11 and the second mounting bracket 12 to move in opposite directions; in addition, in this embodiment, the first mounting bracket 11 and the second mounting bracket 12 are arranged at intervals in the vertical direction, and in this embodiment, the first mounting bracket 11 is arranged above the second mounting bracket 12.

[0042] Reference Figure 3 and Figure 5Two first support rollers 31 are provided on the first mounting frame 11, and the two first support rollers 31 are arranged parallel to each other vertically and spaced apart. At the same time, two second support rollers 32 are also provided on the second mounting frame 12, and the two second support rollers 32 are arranged parallel to each other vertically and spaced apart. The first conveyor belt 35 is wound around the two first support rollers 31 and the two second support rollers 32.

[0043] Reference Figure 2 and Figure 3 A first drive unit 13 is provided on the frame 1. The first drive unit 13 is equipped with a servo motor, and the output shaft of the servo motor is fixedly connected to the first drive roller 34. It is used to drive the first drive roller 34 to rotate. Under the action of the first drive roller 34, the first conveyor belt 35 is driven to rotate, which facilitates the transport of materials on the first conveyor belt 35 to the second conveyor.

[0044] Reference Figure 2 and Figure 3 An adjusting roller 6 and a tensioning roller 61 are provided on the frame 1. Both the adjusting roller 6 and the tensioning roller 61 are slidably connected to the frame 1. Figure 6 An mounting shaft 62 is rotatably connected to the upper part of the adjusting roller 6. A screw 63 is rotatably connected to the mounting shaft 62. The axis of the screw 63 is perpendicular to the axis of the mounting shaft 62, and the screw 63 is threadedly connected to the frame 1. Meanwhile, the first conveyor belt 35 is wound around the adjusting roller 6. The tension roller 61 abuts against the first conveyor belt 35 and pushes the first conveyor belt 35 to protrude towards the second conveying assembly 4, thereby making the first conveyor belt 35 better abut against the first drive roller 34. In addition, the mounting shaft 62 is coaxially rotatably connected to the tension roller 61. An adjusting component is provided on the mounting shaft 62, and the adjusting component is also set as a screw 63. The screw 63 passes through the mounting shaft 62 and is threadedly connected to the frame 1. In this embodiment, the screw 63 on the tension roller 61 and the adjusting roller 6 have the same structure, which can adjust the position of the tension roller 61. Therefore, the screw 63 on the tension roller 61 will not be described in detail.

[0045] Reference Figure 2 and Figure 3 The second conveyor assembly 4 packages the third support roller 41, the fourth support roller 42, the second limit roller 43, the second drive roller 44, and the second conveyor belt 45, in combination. Figure 5The second conveyor belt 45 is wound around the third support roller 41, the fourth support roller 42 and the second drive roller 44. The second limiting roller 43 and the second drive roller 44 are both rotatably connected to the frame 1. At the same time, the second limiting roller 43 abuts against the second conveyor belt 45. The second conveyor belt 45 protrudes away from the first conveying assembly 3, so that the structure of the second conveyor belt 45 is C-shaped and the opening of the second conveyor belt 45 faces the first conveyor belt 35. The third support roller 41 is rotatably connected to the first mounting frame 11 and the fourth support roller 42 rotates on the second mounting frame 12.

[0046] Reference Figure 3 and Figure 5 Two third support rollers 41 are provided on the first mounting frame 11, and the two third support rollers 41 are arranged parallel to each other vertically and spaced apart. At the same time, two fourth support rollers 42 are also provided on the second mounting frame 12, and the two fourth support rollers 42 are arranged parallel to each other vertically and spaced apart. The second conveyor belt 45 is wound around the two third support rollers 41 and the two fourth support rollers 42.

[0047] Reference Figure 2 and Figure 4 A second drive unit 14 is provided on the frame 1. The second drive unit 14 is equipped with a servo motor, and the output shaft of the servo motor is fixedly connected to the second drive roller 44. The servo motor is used to drive the second drive roller 44 to rotate, which in turn drives the second conveyor belt 45 to rotate, thereby facilitating the transport of materials on the second conveyor belt 45 into the packaging machine. An adjusting roller 6 and a tension roller 61 are also provided on the second conveyor belt 45. In this embodiment, the specific structure of the adjusting roller 6 and the tension roller 61 on the second conveying assembly 4 will not be described in detail.

[0048] Reference Figure 2 and Figure 3 A detection element 7 is provided on the first mounting frame 11. In this embodiment, the detection element 7 is a material detection sensor 71, and the model of the material detection sensor 71 is GTB6-N1212. The material detection sensor 71 is located between the first support roller 31 and the third support roller 41. The material detection sensor 71 is used to detect the material conveyed to the second conveyor belt 45. A control element is installed on the frame 1. In this embodiment, the control element is a controller. The control terminal of the controller is used to connect to the drive component. At the same time, the material detection sensor 71 is also connected to the controller.

[0049] Reference Figure 2 and Figure 3Since the material spacing on the first conveyor belt 35 is the same, the time it takes for two adjacent packages of material to pass through the material detection sensor 71 during the conveying process is fixed. When the inspector removes one of the packages of material from the first conveyor belt 35, the corresponding distance between the two packages increases. After the first package of material passes through the material detection sensor 71, the material detection sensor 71 cannot detect the material being conveyed to the second conveyor belt 45 within the same time. At this time, it sends a signal to the controller, which drives the drive assembly 5 to work, thereby moving the first mounting frame 11 away from the packaging machine and the second mounting frame 12 towards the packaging machine. At this time, the distance between the second conveyor belt 45 and the material on the first conveyor belt 35 becomes shorter, and the second conveyor belt 45 catches up with the material. Then the first conveyor belt... The material on conveyor belt 35 can be transported to the second conveyor belt 45 at its own speed, and can also abut against the material pick-up point on the second conveyor belt 45, thereby reducing the occurrence of empty packages and improving the stability of the entire device. When the second conveyor belt 45 catches up with the material, the drive assembly 5 drives the first mounting frame 11 and the second mounting frame 12 to move in opposite directions, so that both the first conveyor belt 35 and the second conveyor belt 45 are in their initial positions. During the movement of the first mounting frame 11 and the second mounting frame 12 driven by the drive assembly 5, since the first conveyor belt 35 and the second conveyor belt 45 have their own drive, the first conveyor belt 35 and the second conveyor belt 45 can transport the material normally, so that the material is transported normally into the packaging machine without affecting the normal production of the entire device. In addition, when conveying wet wipes, when the detection element 7 detects that the material spacing on the first conveyor belt 35 has increased, the second conveyor belt 45 can be moved to follow the material on the first conveyor belt 35, thereby ensuring that the material on the second conveyor belt 45 is adjacent. At the same time, by adjusting the speed of the first conveyor belt 35 and the second conveyor belt 45, the distance between adjacent materials on the second conveyor belt 45 can be changed, thereby reducing the occurrence of arching between adjacent packages caused by the following material pushing the preceding material.

[0050] Reference Figure 4 and Figure 7 The drive assembly 5 includes a synchronous toothed belt 51 and two rotating rollers 52. The two rotating rollers 52 are rotatably connected to the frame 1, and the synchronous toothed belt 51 is wound around the two rotating rollers 52. A third drive member 53 for driving the rotating rollers 52 to rotate is provided on the frame 1. In this embodiment, the third drive member 53 is set as a servo motor. The first mounting frame 11 and the second mounting frame 12 are both set on the synchronous toothed belt 51, and the second mounting frame 12 and the first mounting frame 11 are located in the upper and lower parts of the synchronous toothed belt 51. When the third drive member 53 drives the rotating rollers 52 to rotate, the rotating rollers 52 drive the synchronous toothed belt 51 to rotate. The synchronous toothed belt 51 drives the first mounting frame 11 and the second mounting frame 12 to move in opposite directions in the horizontal direction, thereby facilitating the adjustment of the position of the first conveying assembly 3 and the second conveying assembly 4.

[0051] Reference Figure 4 and Figure 7 A fixing component 9 is provided on the first mounting plate. The fixing component 9 includes a first clamping plate 91 and a second clamping plate 92. The first clamping plate 91 is fixedly mounted on the first mounting plate, and the second clamping plate 92 is slidably connected to the first clamping plate 91. The first clamping plate 91 and the second clamping plate 92 are located on both sides of the synchronous toothed belt 51 and abut against the synchronous toothed belt 51. A mounting hole is provided on the first clamping plate 91, and the mounting hole passes through the synchronous toothed belt 51 and the second clamping plate 92 in sequence. Then, a bolt is inserted into the mounting hole, and the bolt and the first clamping plate 91 and the second clamping plate 92 are fixed to the synchronous toothed belt 51. In addition, in this embodiment, a fixing component 9 is also provided on the second mounting frame 12. The fixing component 9 on the second mounting frame 12 has the same structure as the fixing component 9 on the first mounting frame 11. Therefore, in this embodiment, the structure of the fixing component 9 on the second mounting frame 12 will not be described in detail.

[0052] Reference Figure 4 and Figure 7 A limiting groove 10 is provided on the frame 1. The limiting groove 10 is provided along the length direction of the frame 1. In this embodiment, two limiting grooves 10 are provided and are arranged in parallel and spaced apart. A limiting plate 101 is slidably connected in both limiting grooves 10. One limiting plate 101 is fixedly installed on the first mounting frame 11 by bolts, and the other limiting plate 101 is fixedly installed on the second mounting frame 12 by bolts. When the third driving member 53 drives the synchronous toothed belt 51 to rotate, the first mounting frame 11 and the second mounting frame 12 can slide in the limiting groove 10, so that the first conveying component 3 and the second conveying component 4 move more stably.

[0053] Looking back Figure 1 and Figure 2 Two baffles 20 are installed on the frame 1, and the two baffles 20 are arranged in parallel and spaced apart. The first conveying component 3 and the second conveying component 4 are arranged between the two baffles 20. At the same time, a side plate 201 is provided on the baffle 20. The side plate 201 is arranged along the length of the frame 1 and is fixedly installed on the baffle 20 by multiple bolts 93. Multiple handles 202 are fixedly installed on the side plate 201. In this embodiment, two handles 202 are provided. When disassembly and maintenance are required, the bolts 93 are turned directly, and the side plate 201 is easily removed from the baffle 20 by the handles 202. Then, the tension roller 61 is moved so that the tension roller 61 is no longer in contact with the first conveyor belt 35, and then the first conveyor belt 35 is directly removed from the frame 1. Of course, the same principle applies to removing and replacing the second conveyor belt 45.

[0054] Reference Figure 2 and Figure 3A support assembly 01 is provided on the frame 1. The support assembly 01 is configured in two sets, and the support assembly 01 is used to support the first conveyor belt 35 and the second conveyor belt 45 respectively, thereby making the material transport more stable. The support assembly 01 includes a mounting roller 02, a support belt 03 and multiple support rollers 04. The mounting roller 02 is rotatably connected to the frame 1, and the support belt 03 is wound around the mounting roller 02. One end of the support belt 03 is fixed to the first mounting frame 11, and the other end is fixed to the second mounting frame 12. Under the action of the mounting roller 02, the support belt 03 is U-shaped. At the same time, one support assembly 01 is located inside the first conveyor belt 35 and the other support assembly 01 is located inside the second conveyor belt 45. The support rollers 04 are fixed to the support belt 03 by bolts 93. Multiple support rollers 04 are evenly spaced along the length of the support belt 03. The support rollers 04 above the mounting roller 02 abut against the first conveyor belt 35 or the second conveyor belt 45, thereby improving the stability of the first conveyor assembly 3 and the second conveyor assembly 4 during use.

[0055] The implementation principle of the belt telescopic material conveying device in this application embodiment is as follows: the material is conveyed evenly at intervals on the first conveyor belt 35. Since the conveying speed of the first conveyor belt 35 is greater than that of the second conveyor belt 45, the material transported to the second conveyor belt 45 will be conveyed one package after another on the second conveyor belt 45, and finally enter the packaging machine. When a package of material is removed from the first conveyor belt 35 for detection, the distance between two adjacent packages of material on the first conveyor belt 35 becomes larger. At this time, when a package of material is transported to the second conveyor belt 45 by the material detection sensor 71, if the material detection sensor 71 does not detect the material passing over itself within a specified time, it will send a signal to the controller, causing the controller to drive the drive component 5 to work. When the drive component 5 works, it drives the first mounting frame 11 to move away from the packaging machine. At this time, the distance between the material on the first conveyor belt 35 and the second conveyor belt 45 becomes shorter, so that the material transported to the second conveyor belt 45 can still be transported one package after another on the second conveyor belt 45, reducing the occurrence of empty packages and improving the stability of the entire device.

[0056] 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.
