Description

Technical Field

[0001] This utility model relates to the field of film production and processing equipment technology, and in particular to a traction and pulling device. Background Technology

[0002] PVC film is primarily composed of polyvinyl chloride resin and is commonly used in the construction and packaging industries. After PVC film is manufactured through a calendering process, it needs to be trimmed at both ends to meet customer size requirements. To transport the trimmed film scraps to the PVC film raw material workshop, a scrap-pulling device is typically used. For example, Chinese patent document CN201822044607.6 discloses a scrap recovery mechanism for a PVC film production line, including a scrap-pulling device and a guiding device. The scrap-pulling device includes a support platform, a drive roller rotatably mounted on the support platform, and a clamping shaft located above the drive roller.

[0003] However, since the drive roller and clamping sleeve are rotating at high speed, when workers inspect the production line, their limbs or clothing may be caught in the gap between the drive roller and the clamping sleeve, posing a significant safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a traction pulling device to solve the safety hazards that exist in the use of existing traction devices for recycling PVC film edge materials.

[0005] To achieve the above objectives, the solution provided by this utility model is as follows:

[0006] A traction and material pulling device includes a frame, a drive roller rotatably mounted on the frame, and a clamping roller rotatably mounted above the drive roller; it also includes a support frame, a first blocking plate, and a second blocking plate; the support frame is fixedly mounted on the top of the frame; the shaft end of the clamping roller is rotatably mounted on the support frame; the first blocking plate is horizontally fixed above the clamping roller, and the length direction of the first blocking plate is parallel to the length direction of the clamping roller; the second blocking plate is vertically mounted on the short side of the first blocking plate, and the upper end of the second blocking plate is oscillatingly connected to the first blocking plate; the drive roller and the clamping roller are both located between the opposing support frame and the second blocking plate.

[0007] Optionally, a hanging rod is connected to the short side of the first barrier plate; a hanging ring is provided at the upper end of the second barrier plate, and the hanging ring is sleeved on the hanging rod.

[0008] Optionally, the two shaft ends of the drive roller are connected to rotating rods, and the frame is provided with a first support bearing, on which the rotating rods are rotatably mounted; the frame is provided with a drive mechanism, and the rotating rods are connected to the output shaft of the drive mechanism via a transmission mechanism; the transmission mechanism and the support frame are both located on the same side of the drive roller.

[0009] Optionally, the transmission mechanism includes a driving wheel coaxially arranged with the output shaft of the drive mechanism, a driven wheel fixed on the rotating rod, and a transmission belt wound around both the driving wheel and the driven wheel.

[0010] The frame is detachably connected to a protective cover, and the transmission mechanism is located inside the protective cover.

[0011] Optionally, the support frame includes two threaded guide rods vertically mounted on the top of the frame, a support plate horizontally mounted and movably sleeved on the two threaded guide rods, a second support bearing mounted on the support plate, and adjusting nuts located on the upper and lower sides of the support plate and sleeved on the threaded guide rods; the shaft end of the clamping roller is rotatably connected to the second support bearing.

[0012] Optionally, a washer is also fitted onto the threaded guide rod, and the washer is located between the adjusting nut and the support plate.

[0013] Optionally, a support rod is fixedly connected to the bottom of the first barrier plate, and the support rod is fixed to the support plate.

[0014] Optionally, both the first and second barrier plates are barrier mesh panels.

[0015] Optionally, two vertically arranged third barrier plates are connected to each of the two long sides of the first barrier plate, and an edge material inlet or edge material outlet is formed between the two third barrier plates in the same vertical direction.

[0016] Beneficial effects:

[0017] This invention creates a barrier above the clamping roller by installing a first barrier plate. A second barrier plate is then installed on the short side of the first barrier plate, confining the drive roller and clamping roller within the working area between the support frame and the second barrier plate. This effectively prevents workers' limbs or clothing from accidentally approaching the high-speed rotating drive roller and clamping roller, significantly reducing the risk of entanglement. Without affecting the traction and pulling of the film edge material by the traction and pulling device, it also reduces safety hazards during the use of the traction and pulling device.

[0018] Furthermore, by swinging the upper end of the second barrier plate to the first barrier plate, this invention allows the second barrier plate to swing counterclockwise and be placed on the first barrier plate, thus facilitating worker maintenance of the drive roller and clamping roller. At the same time, it also makes it convenient for manual pulling of film edge material between the clamping roller and the drive roller in the early stages of production. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0036] Please see Figures 1 to 6 This utility model provides a traction and material pulling device, which can be installed beside a PVC film width-fixing cutting device (the PVC film width-fixing cutting device can be the PVC roll material width-fixing cutting device disclosed in CN202422140894.6). Multiple devices can be used simultaneously, or they can be used in conjunction with the guiding device of an existing edge material recycling mechanism. Specifically, the traction and material pulling device includes a frame 1, a drive roller 2 rotatably mounted on the frame 1, a clamping roller 3 rotatably mounted on the upper side of the drive roller 2, a support frame 4 fixedly mounted on the top of the frame 1, and a first blocking plate 5 and a second blocking plate 6.

[0037] The clamping roller 3 is rotatably mounted on the support frame 4. In the initial stage of production, the cut film edge material needs to be manually pulled between the clamping roller 3 and the drive roller 2. Then, the clamping roller 3 presses itself against the drive roller 2, clamping the film edge material. When the drive roller 2 rotates, friction drives the clamping roller 3 to rotate synchronously, achieving clamping and pulling of the film edge material, thus transporting it to the PVC film raw material workshop. The first barrier plate 5 is horizontally fixed above the clamping roller 3, and its length direction is parallel to the length direction of the clamping roller 3. The second barrier plate 6 is vertically mounted on the short side of the first barrier plate 5. The drive roller 2 and the clamping roller 3 are both located between the opposing support frame 4 and the second barrier plate 6.

[0038] This invention creates a barrier above the clamping roller 3 by setting a first barrier plate 5 above the clamping roller 3. Furthermore, by setting a second barrier plate 6 on the short side of the first barrier plate 5, the drive roller 2 and the clamping roller 3 are confined within the working area between the support frame 4 and the second barrier plate 6. This effectively prevents workers' limbs or clothing from accidentally approaching the high-speed rotating drive roller 2 and clamping roller 3, significantly reducing the risk of being caught in them. While not affecting the traction and pulling of the film edge material by the traction and pulling device, it also reduces safety hazards during the use of the traction and pulling device.

[0039] Furthermore, by making the upper end of the second barrier plate 6 swing and connect it to the first barrier plate 5, the second barrier plate 6 can swing counterclockwise and be placed on the first barrier plate 5, which makes it easier for workers to maintain the drive roller 2 and the clamping roller 3. At the same time, it is also convenient for manual pulling of the film edge material between the clamping roller 3 and the drive roller 2 in the early stage of production.

[0040] like Figure 1 and Figure 2 As shown, in order to enable the second barrier plate 6 to swing flexibly, in an optional embodiment, a hanging rod 7 is connected to the short side of the first barrier plate 5, and the hanging rod 7 can be fixed to the short side of the first barrier plate 5 by welding; the upper end of the second barrier plate 6 is provided with a hanging ring 8, and the hanging ring 8 is sleeved on the hanging rod 7.

[0041] Since the hanging ring 8 is sleeved on the hanging rod 7, the hanging ring 8 can rotate freely around the hanging rod 7, so that the second barrier plate 6 can swing flexibly and be placed on the first barrier plate 5. This makes it convenient for workers to maintain the drive roller 2 and the clamping roller 3, and also makes it convenient for manual pulling of the film edge material into the working area in the early stage of production.

[0042] like Figure 3 and Figure 4As shown, in an optional embodiment, the two shaft ends of the drive roller 2 are connected to rotating rods 9, and the frame 1 is provided with a first support bearing 10, on which the rotating rods 9 are rotatably mounted. The first support bearing 10 can reduce the frictional resistance when the rotating rods 9 rotate, ensuring the smoothness of the drive roller 2 rotation. At the same time, through the cooperation between the rotating rods 9 and the first support bearing 10, the rotation of the drive roller 2 is constrained in a specific axial direction, preventing the drive roller 2 from deviating during rotation, thereby ensuring the transmission accuracy and stability between the drive roller 2 and the clamping roller 3, and providing a reliable power transmission basis for the traction of film edge material.

[0043] like Figure 1 and Figure 4 As shown, the frame 1 is further provided with a drive mechanism 11, which can be a drive motor. The rotating rod 9 is connected to the output shaft of the drive mechanism 11 via a transmission mechanism 12. In order to ensure that the setting of the transmission mechanism 12 does not affect the manual pulling of the film edge material between the clamping roller 3 and the drive roller 2, and to ensure that the second blocking plate 6 can be vertically set on the short side of the first blocking plate 5 without being interfered with by the transmission mechanism 12, the transmission mechanism 12 and the support frame 4 are both set on the same side of the drive roller 2.

[0044] like Figure 1 As shown, in an optional embodiment, the transmission mechanism 12 includes a driving wheel 121 coaxially arranged with the output shaft of the drive mechanism 11, a driven wheel 122 fixed on the rotating rod 9, and a transmission belt 123 simultaneously wound around the driving wheel 121 and the driven wheel 122. The driving wheel 121 and the driven wheel 122 can be pulleys or sprockets, and the transmission belt 123 can be a transmission belt or a chain.

[0045] The frame 1 is detachably connected (the protective cover 13 can be connected to the frame 1 via screws) to a protective cover 13, and the transmission mechanism 12 is located inside the protective cover 13. The protective cover 13 can prevent workers from accidentally coming into contact with high-speed rotating transmission components, reducing the risk of safety accidents. When maintenance or repair of the transmission mechanism 12 is required, the detachable protective cover 13 can be quickly disassembled and installed without affecting the normal maintenance process of the equipment, thus improving the convenience of equipment maintenance while ensuring safety and transmission reliability.

[0046] like Figure 1 as well as Figures 3 to 5As shown, in order to adjust the height of the clamping roller 3 so that the traction and material pulling device can pull and convey film edge materials of different thicknesses, in an optional embodiment, the support frame 4 includes two threaded guide rods 401 vertically mounted on the top of the frame 1, a support plate 402 horizontally mounted and movably sleeved on the two threaded guide rods 401, a second support bearing 403 mounted on the support plate 402, and adjusting nuts 404 located on the upper and lower sides of the support plate 402 and sleeved on the threaded guide rods 401; the shaft end of the clamping roller 3 is rotatably connected to the second support bearing 403. When it is necessary to adjust the height of the clamping roller 3, by rotating the adjusting nuts 404 on the upper and lower sides of the support plate 402, the support plate 402 can move up and down along the threaded guide rods 401, thereby driving the second support bearing 403 and the clamping roller 3 to rise and fall synchronously, thus realizing the adjustment of the height of the clamping roller 3.

[0047] To prevent breakage at the connection between the clamping roller 3 and the second support bearing 403, and to ensure that the clamping roller 3 meets the requirements for lightweighting, the clamping roller 3 can be made of aluminum alloy and adopt a hollow tubular structure.

[0048] like Figure 4 and Figure 5 As shown, in an optional embodiment, a washer 405 is also fitted onto the threaded guide rod 401, and the washer 405 is located between the adjusting nut 404 and the support plate 402. In this embodiment, by fitting the washer 405 between the adjusting nut 404 and the support plate 402 onto the threaded guide rod 401, the washer 405 fills the gap between the adjusting nut 404 and the support plate 402, preventing the adjusting nut 404 from directly contacting the support plate 402 and causing wear. Simultaneously, it increases the force-bearing area between the adjusting nut 404 and the support plate 402, ensuring that the pressure applied by the adjusting nut 404 is evenly distributed on the support plate 402, preventing the support plate 402 from deforming due to excessive localized force. This, in turn, ensures the stability and accuracy of the height adjustment of the clamping roller 3, enabling the traction and feeding device to smoothly pull and feed the film edge material.

[0049] like Figure 3 and Figure 4 As shown, optionally, a support rod 14 is fixedly welded to the bottom of the first barrier plate 5, and the support rod 14 is fixedly welded to the support plate 402. The bottom of the first barrier plate 5 is fixed to the support plate 402 by the support rod 14, so the first barrier plate 5 can be moved up and down synchronously by means of the lifting adjustment of the support plate 402, thereby ensuring that the first barrier plate 5 is always in a suitable position above the clamping roller 3, and continuously forming an effective barrier.

[0050] In an optional embodiment, both the first barrier plate 5 and the second barrier plate 6 are barrier mesh panels. The barrier mesh panels can be made of lightweight materials such as aluminum alloy, engineering plastics, or carbon fiber, which can significantly reduce the overall weight of the barrier plates. This not only makes the swinging operation of the second barrier plate 6 easier and more flexible, facilitating maintenance and edge material traction, but also reduces the load-bearing pressure on the support frame 4 from the first barrier plate 5 and the second barrier plate 6.

[0051] like Figure 6 As shown, as an extension, two vertically arranged third barrier plates 15 are connected to each of the two long sides of the first barrier plate 5. An edge material inlet or outlet is formed between the two third barrier plates 15 in the same vertical direction. The third barrier plate 15, together with the first barrier plate 5 and the second barrier plate 6, forms a semi-enclosed protective structure, further enhancing the blocking effect on workers' limbs and clothing, and improving the safety of equipment use. Moreover, the third barrier plate 15 can also precisely guide the conveying path of the film edge material. After entering from the edge material inlet, the film edge material, under the limiting action of the third barrier plate 15, can pass more smoothly through the gap between the drive roller 2 and the clamping roller 3, and then exit from the edge material outlet, preventing the edge material from shifting or tangling during traction, ensuring the stability and reliability of edge material traction. Similarly, the third barrier plate 15 can be a barrier mesh plate. The third barrier plate 15 can be hung on the first barrier plate 5 via hooks.

[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
