Description

Technical Field

[0001] This utility model relates to the field of PVC roll production equipment, and in particular to an embossing component and a PVC roll production equipment. Background Technology

[0002] PVC (polyvinyl chloride) roll materials typically include PVC film, PVC wallpaper, and PVC flooring. To give PVC roll materials decorative properties, existing technologies involve embossing the surface of the PVC roll material, thus creating a natural texture. For example, Chinese patent document CN201721017246.5 discloses an embossing device suitable for PVC sheets. This embossing device is located below a laminating device and includes an embossing roller, a pressure roller, a support, a guide rail, and multiple rollers. The rollers move along the guide rail, and limit plates are provided at both ends of the guide rail to limit the movement distance of the embossing device and prevent it from moving off the guide rail during movement.

[0003] However, in the aforementioned embossing device, the limiting plate does not have the function of locking the embossing device. It can only prevent the embossing device from moving out of the guide rail when it moves to the end of the guide rail. It cannot prevent the embossing device from making small or gradual movements during the production process, which will lead to a decrease in the embossing accuracy of the PVC roll.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] The purpose of this utility model is to provide an embossing component and a production device for PVC rolls, which aims to solve the problem that the existing embossing device for PVC sheets does not have a locking function, and the embossing device is prone to slight or gradual movement during the production process, which leads to a decrease in the embossing accuracy of PVC rolls.

[0006] To achieve the above objectives, the solution provided by this utility model is as follows:

[0007] The first aspect of this utility model provides an embossing assembly, including a movable support, an embossing roller and a pressing roller rotatably mounted on the movable support, a guide rail horizontally positioned below the movable support, and a traveling wheel rotatably positioned at the bottom of the movable support; the axial direction of the embossing roller is parallel to the length direction of the guide rail; and further includes:

[0008] Support columns, at least two of which are vertically fixed and distributed along the length of the guide rail on one side of the guide rail;

[0009] The longitudinal beam is horizontally fixed to the support column along the axial direction of the embossing roller;

[0010] Locking rod seat, the locking rod seat is fixedly mounted on the movable bracket;

[0011] A locking rod is inserted into the locking rod seat along the width direction of the movable bracket and inserted into the longitudinal beam.

[0012] Optionally, there are two locking rod seats, which are fixedly mounted on both sides of the movable bracket.

[0013] Optionally, the locking rod has external threads, and limit nuts are threadedly connected to both sides of the locking rod seat.

[0014] Optionally, the walking wheels are provided in multiple sets, each set of walking wheels including at least two parallel walking wheels and a rotating rod for connecting the walking wheels; the movable bracket is provided with a drive motor, and a transmission mechanism is connected between the output shaft of the drive motor and the rotating rod.

[0015] Optionally, the transmission mechanism includes a driving wheel connected to the output shaft of the drive motor, a driven wheel fixed on the rotating rod, and a transmission belt wound around both the driving wheel and the driven wheel; the transmission belt is a chain transmission belt or a transmission belt.

[0016] Optionally, the embossing roller is a cooled embossing roller; the pressing roller is a cooled pressing roller, and the surface of the pressing roller is provided with a rubber layer.

[0017] Optionally, the movable support includes two vertically arranged and opposite side plates; each of the two side plates is slidably provided with a bearing seat, and the two ends of the pressure roller are respectively rotatably connected to the two bearing seats.

[0018] Optionally, a hydraulic cylinder is provided at the top of each of the two side plates. The telescopic rod of the hydraulic cylinder is perpendicular to the axis of the pressing roller, and the telescopic rod of the hydraulic cylinder is connected to the bearing seat.

[0019] The second aspect of this utility model provides a PVC roll production apparatus, including the aforementioned embossing component.

[0020] Beneficial effects:

[0021] This invention provides an embossing assembly. By fixing a longitudinal beam to a support column, the longitudinal beam provides reliable positioning support for the embossing assembly when it is positioned below the bonding roller. When the locking rod passes through the locking rod seat along the width direction of the movable bracket and is inserted into the longitudinal beam, the movable bracket is stably limited and will not produce slight or gradual displacement. At this time, the embossing assembly is exactly in the normal production position below the bonding roller, which can ensure that the relative position between the embossing roller and the roll material remains constant. This avoids problems such as roll material texture shift and uneven depth caused by the movement of the embossing assembly, and helps to improve the embossing accuracy of PVC roll materials.

[0036] Please see Figures 1 to 7 The first aspect of this utility model provides an embossing component, which can be part of an existing PVC roll production device, and during production, the embossing component is located below the bonding roller 18. After multiple layers of rolls are bonded together by the bonding roller 18, the bonded PVC rolls 20 can be drawn to the embossing component for embossing. After the PVC rolls 20 have been embossed with patterns, they are drawn to a cooling component downstream of the embossing component for cooling by the cooling rollers of the cooling component.

[0037] Specifically, the embossing assembly includes a movable support 1, an embossing roller 2, a pressing roller 3, a guide rail 4, and wheels 5. The embossing roller 2 and the pressing roller 3 are rotatably mounted on the movable support 1, arranged side-by-side, with the pressing roller 3 positioned upstream of the embossing roller 2. During production, the laminated PVC roll 20 passes downwards through the gap between the pressing roller 3 and the embossing roller 2, and the roll 20 comes into contact with the embossing roller 2. The embossing of the PVC roll surface is achieved through the rotation of the embossing roller 2 combined with the pressing action of the pressing roller 3. The embossing roller 2 can be driven by a motor or rotated by the traction of a cooling roller downstream of the embossing assembly. The traveling wheel 5 is rotatably mounted on the bottom of the movable bracket 1 and rolls along the guide rail 4. The length direction of the guide rail 4 is parallel to the axis of the pressing roller 3 and the embossing roller 2, so that the movable bracket 1 can move to the outside of the bonding roller 18 in a direction perpendicular to the production of PVC roll 20, which provides convenience for production personnel to complete the disassembly and replacement of the embossing roller 2 with the help of a crane.

[0038] The embossing assembly also includes support columns 6, longitudinal beams 7, locking rod seats 8, and locking rods 9. At least two support columns 6 are vertically fixed, and the support columns 6 are distributed along the length of the guide rail 4 on one side of the guide rail 4. The support columns 6 can be part of the mounting frame for the bonding roller 18. The longitudinal beam 7 is horizontally fixed to the support columns 6 along the axial direction of the embossing roller 2. The locking rod seat 8 is fixedly mounted on the movable bracket 1; the locking rod 9 passes through the locking rod seat 8 along the width direction of the movable bracket 1, and is inserted into the longitudinal beam 7, which has a through hole for the locking rod 9 to be inserted.

[0039] By fixing the longitudinal beam 7 to the support column 6, the longitudinal beam 7 can provide reliable positioning support for the embossing component when it is located below the bonding roller 18. When the locking rod 9 passes through the locking rod seat 8 along the width direction of the movable bracket 1 and is inserted into the longitudinal beam 7, the movable bracket 1 is stably limited and will not move slightly or gradually. At this time, the embossing component is exactly in the normal production position below the bonding roller 18, which can ensure that the relative position of the embossing roller 2 and the roll material 20 is always stable, thereby avoiding the problem of uneven texture and uneven depth of the roll material 20 due to the movement of the embossing component, which helps to improve the embossing accuracy of the PVC roll material 20. When it is necessary to move the embossing component (for example, when it is necessary to replace the embossing roller 2), the restriction on the movable bracket 1 can be released by pulling out the locking rod 9.

[0040] like Figures 1 to 3As shown, in an optional embodiment, two locking rod seats 8 are provided, and the two locking rod seats 8 are respectively fixed on both sides of the movable bracket 1. In this embodiment, by providing locking rod seats 8 on both sides of the movable bracket 1, the two locking rods 9 can be simultaneously inserted into the longitudinal beam 7 from both sides of the movable bracket 1, forming a two-way mechanical fixing effect. This ensures that the embossing assembly is subjected to balanced force during normal production under the bonding roller 18, effectively preventing the offset or shaking that may be caused by unilateral fixing, thereby improving the stability and accuracy of the embossing operation of the PVC roll 20.

[0041] like Figure 1 and Figure 2 As shown, in an optional embodiment, the locking rod 9 has external threads, and limit nuts 10 are threadedly connected to both sides of the locking rod seat 8. The limit nuts 10 on both sides of the locking rod seat 8 can form a bidirectional fixation from both ends of the locking rod seat 8, further restricting the axial movement of the locking rod 9 within the locking rod seat 8, enhancing the stability of the movable bracket 1 in limiting the movement, effectively avoiding minor displacement caused by the loosening of the locking rod 9 when the embossing assembly is in normal production below the bonding roller 18, and ensuring the accuracy of the relative position between the embossing roller 2 and the roll material 20.

[0042] like Figure 1 and Figure 2 As shown, in an optional embodiment, a washer 19 is fitted on the locking rod 9. The washer 19 is located between the locking rod seat 8 and the limiting nut 10. It can increase the contact area between the limiting nut 10 and the surface of the locking rod seat 8, disperse the pressure of the limiting nut 10 on the locking rod seat 8, and avoid local wear of the locking rod seat 8 due to pressure concentration during the locking process. At the same time, it can enhance the friction between the two, reduce the loosening of the limiting nut 10 due to vibration of the embossing assembly during operation, further improve the stability of the locking rod 9 in limiting the movable bracket 1, ensure that the embossing assembly does not shift in the normal production position, and ensure the embossing accuracy of the PVC roll 20.

[0043] like Figure 5 As shown, in an optional embodiment, the walking wheels 5 are provided in multiple sets, each set of walking wheels 5 including at least two parallel walking wheels 5 and a rotating rod 11 for connecting the walking wheels 5; the movable bracket 1 is provided with a drive motor 12, and a transmission mechanism 13 is connected between the output shaft of the drive motor 12 and the rotating rod 11. The movable bracket 1 provided by this utility model can be pushed manually. Of course, to save manpower, the drive motor 12 can also be used to drive the movable bracket 1. For example, the drive motor 12 is connected to the rotating rod 11 through the transmission mechanism 13, which can realize the power drive of the walking wheels 5, replacing manual pushing to save manpower.

[0044] like Figure 5 and Figure 6As shown, in an optional embodiment, the transmission mechanism 13 includes a drive wheel 131 connected to the output shaft of the drive motor 12, a driven wheel 132 fixedly mounted on the rotating rod 11, and a transmission belt 133 simultaneously wound around the drive wheel 131 and the driven wheel 132. The transmission mechanism 13 adopts a structure where the drive wheel 131, driven wheel 132, and transmission belt 133 cooperate. The drive wheel 131 is connected to the output shaft of the drive motor 12, the driven wheel 132 is fixed to the rotating rod 11, and the transmission belt 133 is wound around both synchronously. This allows for stable transmission of power from the drive motor 12 to the rotating rod 11, ensuring uniform force distribution and synchronous rotation of the traveling wheel 5, and guaranteeing the smooth movement of the movable support 1 along the guide rail 4. The transmission belt 133 is a chain drive belt or a transmission belt. Chain drive provides higher transmission efficiency and load-bearing capacity, is suitable for heavy-duty conditions, and offers stable transmission accuracy.

[0045] In an optional embodiment, the embossing roller 2 is a cooling embossing roller; the pressing roller 3 is a cooling pressing roller, and the surface of the pressing roller 3 is provided with a rubber layer. Cooling fluid is circulated inside both the cooling embossing roller and the cooling pressing roller. The cooling fluid can be cooling water or low-temperature heat-conducting oil. By circulating cooling fluid into the cooling embossing roller and the cooling pressing roller, the cooling fluid can remove heat from the surface of the roller body 21, thereby reducing the roller surface temperature; when the roller surface temperature is stable and suitable, a high-quality embossing effect can be obtained, and the smoothness of the PVC roll 20 can be improved. The rubber layer is elastic and can control the pressure of the cooling pressing roller, making the texture on the surface of the PVC roll 20 smoother.

[0046] like Figure 7 As shown, in an optional embodiment, both the embossing roller 2 and the pressing roller 3 include a roller body 21, a rotating drum 22, a rotary joint 23, a coolant inlet pipe 24, and a coolant outlet pipe 25. The roller body 21 has an internal cavity 211 for containing coolant. The rotating drum 22 communicates with the internal cavity 211 and is rotatably connected to a bearing seat 14 mounted on the movable support 1. Preferably, the rotating drum 22 is located at one end of the roller body 21 facing the area where the embossing assembly moves out (the other end of the roller body 21 is fixedly connected to a rotating shaft, which is rotatably connected to the bearing seat 14). The rotary joint 23 is connected to the rotating drum 22. When embossing the PVC roll 20, the roller body 21 and the rotating drum 22 rotate together, while the rotary joint 23 remains stationary, thereby allowing coolant to be supplied to the interior of the roller body 21 through the coolant inlet pipe 24 and the coolant outlet pipe 25.

[0047] The coolant inlet pipe 24 and coolant outlet pipe 25 are both connected to a coolant circulation pipeline, which is not shown in the attached diagram. However, it is understood that this circulation pipeline can be connected to the cooling tower in the workshop to ensure that the coolant inside the roller 21 can be cooled after heating and reused.

[0048] The coolant inlet pipe 24 and the rotary joint 23 are fixedly connected. The coolant inlet pipe 24 extends into the inner cavity 211 through the interior of the rotary joint 23 and the inside of the rotating drum 22, thereby allowing the coolant to be delivered into the roller body 21. The rotary joint 23 is provided with a coolant outlet, which is connected to the coolant outlet pipe 25, so that the coolant flows into and out of the roller body 21 from the rotary joint 23. Since the rotating drum 22 and the rotary joint 23 are both located at the end of the roller body 21 facing the area where the embossing assembly moves out, when the production personnel need to move the embossing assembly to the outside of the bonding roller 18, the production personnel can remove the circulating conveying pipe from the coolant inlet pipe 24 and the coolant outlet pipe 25 from the outside of the bonding roller 18, making the disassembly and assembly of the circulating conveying pipe more convenient.

[0049] like Figure 1 and Figure 2 As shown, in an optional embodiment, both the outer ends of the coolant inlet pipe 24 and the coolant outlet pipe 25 are provided with pipe fittings 16, which are used to connect to a flexible circulation delivery pipe. The flexible circulation delivery pipe has the ability to extend and retract, therefore, there is no difficulty in removing or reinstalling the circulation delivery pipe from the coolant inlet pipe 24 and the coolant outlet pipe 25, ensuring that the embossed assembly can move.

[0050] like Figure 6 As shown, in an optional embodiment, the movable support 1 includes two vertically arranged and oppositely positioned side plates 101; each of the two side plates 101 has a slidably mounted bearing seat 14 on its top, and the two ends of the pressure roller 3 are rotatably connected to the two bearing seats 14 via the aforementioned rotating shaft and rotating cylinder 22, respectively. The bearing seats 14 are slidably mounted on the top of the side plates 101, allowing the pressure roller 3 to move, thereby adjusting the distance between the pressure roller 3 and the embossing roller 2, ensuring the embossing effect. Simultaneously, during pre-production, the pressure roller 3 and the embossing roller 2 can be spaced a relatively wide distance, allowing the PVC roll 20 to be smoothly fed between them. To enable the bearing seats 14 to slide, a slide rail 17 is provided on the top of each side plate 101, with the axial direction of the slide rail 17 perpendicular to the axial direction of the pressure roller 3.

[0051] like Figure 6 As shown, in an optional embodiment, each of the two side plates 101 is equipped with a hydraulic cylinder 15 at its top. The telescopic rod of the hydraulic cylinder 15 is perpendicular to the axis of the pressing roller 3, and the telescopic rod of the hydraulic cylinder 15 is connected to the bearing seat 14. During operation, the hydraulic cylinder 15 can generate a large thrust, thereby ensuring that the pressing roller 3 keeps the PVC roll 20 pressed.

[0052] The second aspect of this utility model provides a PVC roll production apparatus, including the aforementioned embossing assembly. The embossing assembly achieves stable positioning through the cooperation of a support column 6, a longitudinal beam 7, a locking rod seat 8, and a locking rod 9, preventing movement of the embossing assembly from affecting the embossing accuracy.

[0053] 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.
