Description

Technical Field

[0001] This utility model relates to the field of PVC sheet processing technology, and in particular to a quick roller changing embossing device for PVC sheets. Background Technology

[0002] PVC sheets, a polymer material widely used in packaging, building materials, and decoration, require surface embossing as a key process to enhance product texture, functionality, and added value. The embossing process involves contacting the heated PVC sheet with the pattern on the surface of an embossing roller, creating corresponding textures to meet the needs of different applications. In PVC sheet production, the embossing roller is a core component, as its surface pattern directly determines the final appearance of the product. With the increasing market demand for diversified and personalized PVC sheets, manufacturers need to frequently change embossing rollers with different patterns to adapt to multi-variety, small-batch order patterns. Therefore, the efficiency of embossing roller replacement has become a crucial factor affecting production continuity and reducing production costs.

[0003] A search revealed Chinese Patent Publication No. CN216683024U, which discloses a calender for PVC sheet processing with a quick-change roller mechanism. This invention relates to the field of PVC sheet processing technology and includes a drive unit. A clamping device is inserted into the right side of the drive unit, and a support device is fitted around the outside of the drive unit. The drive unit includes a pulley, and a rotating shaft is fixedly connected to the right side of the pulley. The clamping device includes a fixing ring, and fixing rods are movably connected to the outside of the fixing ring via pins at equal intervals. Pressure rods are movably connected to the fixing rods. Rotating a reverse-rotation handwheel causes the lead screw to rotate in the opposite direction, moving the threaded ring away from the fixing ring. This causes the pressure rods to move towards the rotating shaft, thus preventing them from pressing the rollers. The operator can then remove the rollers. When installing new rollers, the roller is fitted around the outside of the pressure rods, and the handwheel is rotated in the forward direction to quickly fix the rollers, thus solving the problem of long roller-changing times in existing devices.

[0004] The aforementioned patent specification describes a device that uses a rotating handwheel to drive a lead screw, causing the threaded ring to move and thus controlling the pressure bar's compression and release of the rollers. This addresses the issue of long roller replacement times in traditional devices to some extent. However, in actual production, when multiple embossing rollers need to be replaced, operators must manually rotate the handwheel and adjust the pressure bar for each roller. This repetitive process significantly increases labor intensity and leads to excessively long roller replacement times. Furthermore, the fixation of each embossing roller relies on manual adjustment of the handwheel, making it difficult to guarantee the relative positional accuracy between multiple rollers. This results in inaccurate pattern alignment during the embossing process, ultimately causing unstable embossing quality on PVC sheets. Therefore, a rapid roller replacement embossing device for PVC sheets is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick roller changing embossing device for PVC sheets, which aims to improve the problems in the prior art where the operation of changing multiple embossing rollers is cumbersome and time-consuming, and the installation and positioning are prone to deviation, resulting in unstable embossing quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A quick roller changing embossing device for PVC sheets includes a support frame, a vertical frame body fixedly connected to the top of the support frame, a plurality of mounting slots opened inside the vertical frame body, a guide mechanism provided inside the vertical frame body, and a locking mechanism provided inside each mounting slot.

A positioning groove is formed on the inner wall of the other side of the mounting slot. A return spring is fitted inside the positioning groove. A positioning bead is slidably connected inside the positioning groove. Quick-connect sockets are fixedly connected to adjacent sides of the support frame. A drive assembly is installed on the outer side of the vertical frame. Through the above technical solution: the support frame of the guide mechanism fixes the quick-connect socket, the guide slide rail guides the movement trajectory, the rotating shaft makes the support plate rotate, the reset spring in the positioning groove pushes the positioning bead to clamp the support plate to limit the position, the fixed roller groove assists in supporting the sheet, the drive component provides power, and the cooperation of each structure improves the roller changing efficiency and operation stability.

[0007] As a further description of the above technical solution: The locking mechanism includes two bearing seats, with sliders fixedly connected to both outer sides of the two bearing seats, a driver fixedly connected to the adjacent side of each bearing seat, an embossing roller fixedly connected to the output end of the adjacent side of the driver, support blocks slidably connected to both inner sides of each bearing seat, toothed plates fixedly connected to the adjacent side of each of the two support blocks, a handle rotatably connected to the inside of each bearing seat, a transmission gear fixedly connected to one outer end of the handle, and locking blocks fixedly connected to both outer sides of each bearing seat. The above technical solution involves the locking mechanism's slider cooperating with the slide rail to make the bearing seat slide, the handle driving the transmission gear and toothed plate to drive the support block to extend and retract, the locking block restricting the support block, and the driver driving the embossing roller to work, ensuring the stable operation of the embossing roller and improving the embossing quality.

[0008] As a further description of the above technical solution: The external part of the transmission gear is installed inside the two support blocks on the adjacent side, and the external part of the transmission gear is meshed with the toothed plate. The above technical solution involves installing the transmission gear between the support blocks and meshing with the toothed plate. When rotating, it drives the two support blocks to move synchronously in opposite directions, thereby enabling the bearing seat to be quickly locked or released, making the operation convenient and efficient.

[0009] As a further description of the above technical solution: The support block is externally slidably connected to the outside of the locking block, and the locking block causes the outside of the support block to engage with the inside of the bearing seat and restricts its sliding range. Through the above technical solution: the support block slides outside the locking block, and the locking block restricts it inside the bearing seat, preventing the support block from falling off, ensuring reliable locking function, and enhancing the stability of the bearing seat.

[0010] As a further description of the above technical solution: The drive assembly includes a drive device, which is externally fixedly connected to the outside of the vertical frame. The output end of the drive device is fixedly connected to a connector, and the other end of the connector is fixedly connected to the inside of the quick-connect socket. Through the above technical solution: the drive unit of the drive component is fixed on the vertical frame, and the output end is connected to the quick-connect socket via a connector to stably transmit power and provide continuous driving force for the operation of the embossing roller.

[0011] As a further description of the above technical solution: The top of the quick-connect socket is supported on the outside of the driver, so that the connector mates with the driver; The above technical solution uses a quick-connect socket to support the driver, enabling precise docking between the connector and the driver, ensuring efficient power transmission, and ensuring that the embossing roller receives power in a timely manner, thereby improving response speed.

[0012] As a further description of the above technical solution: The positioning bead is externally supported on one end of the return spring, and the other end of the support plate is snapped onto the outside of the return spring. The above technical solution involves a positioning bead supported on a return spring, a support plate engaging the return spring, and the spring force of the return spring causing the positioning bead to be tightly engaged with the support plate, thus stabilizing and limiting the position of the bearing seat and ensuring stable operation of the equipment.

[0013] As a further description of the above technical solution: By sliding the bearing seat from one end of the guide rail to the mounting groove, the sliders on both sides of the bearing seat are engaged with the outside of the guide rail. When the bearing seat is engaged with the inside of the mounting groove, the support plate is rotated to the outside of the positioning groove, so that the positioning ball is engaged with the outside of the support plate, restricting the position of the bearing seat inside the mounting groove, and causing the driver to engage with the top of the quick-connect socket. Through the above technical solution: the bearing seat slides into the installation groove along the guide rail via the slider, the support plate is locked by the positioning ball after rotation, and the driver connects with the quick-connect socket to realize the rapid and accurate installation of the embossing roller, shorten the roller change time, and improve production efficiency.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the bearing seat slides along a set trajectory through the cooperation of the guide rail and the slider. The support plate rotates through the rotating shaft. The support plate is limited by the reset spring and positioning ball in the positioning groove, and the bearing seat is firmly locked in the position in the mounting groove. The position of the quick connector is fixed by the support frame, and the quick connector is precisely connected to the driver, so that the power transmission channel is quickly connected, thereby improving the roller changing efficiency, greatly shortening the roller changing time, and ensuring accurate and stable positioning, ensuring that the embossing roller is installed in the same position, and avoiding the effect of embossing quality due to positioning deviation.

[0015] 2. In this utility model, with the cooperation of the handle driving the transmission gear to rotate, the transmission gear meshes with the toothed plate to drive the support block to slide within the limiting range of the locking block. With the cooperation of the bearing seat connecting with the driver and the embossing roller, the embossing roller can rotate stably under the action of driving force. With the cooperation of the slider and the guide rail sliding, the locking mechanism as a whole can move quickly, so as to solve the problem that it is necessary to use tools to loosen the fixed structure, which causes the equipment to be stuck for a long time when changing rollers. This not only makes the operation cumbersome, but also seriously affects the pressing and processing efficiency of different batches of sheets. Attached Figure Description

The other end of the connector 42 is connected to the inside of the quick-connect socket 39 to ensure that the power can be transmitted smoothly.

[0021] Reference Figure 2 , Figure 5 and Figure 6The locking mechanism 5 includes two bearing seats 51, which provide mounting support for the driver 53 and the embossing roller 54. Slider 52 is fixedly connected to both outer sides of the two bearing seats 51. The slider 52 cooperates with the guide rail 33 to enable the bearing seats 51 to slide smoothly. Driver 53 is fixedly connected to the adjacent side of the bearing seats 51. Driver 53 can directly drive the embossing roller 54 to rotate. The output end of the adjacent side of the driver 53 is fixedly connected to the embossing roller 54. The embossing roller 54 is a key component for realizing the embossing of PVC sheets. Its surface texture determines the embossing effect. Support blocks 55 are slidably connected to both inner sides of the bearing seats 51. The support blocks 55 can extend out of the bearing seats 51 to enhance the stability of the bearing seats 51 after installation. A toothed plate 56 is fixedly connected to one of the adjacent sides of each of the two support blocks 55. The toothed plate 56 cooperates with the transmission gear 58 to enable the support block 55 to slide. A handle 57 is rotatably connected inside the bearing seat 51. The handle 57 allows the operator to rotate the transmission gear 58. The transmission gear 58 is fixedly connected to one end of the handle 57. When the transmission gear 58 rotates, it can drive the toothed plate 56 to move, thereby causing the support block 55 to slide. A locking block 59 is fixedly connected to both sides of the outer side of the bearing seat 51. The locking block 59 can limit the sliding range of the support block 55 and prevent it from sliding out of the bearing seat 51. The transmission gear 58 is installed inside the adjacent side of the two support blocks 55 to ensure that the transmission gear 58 and the toothed plate 56 can mesh accurately. The transmission gear 58 is meshed with the toothed plate 56, so that when the transmission gear 58 rotates, it can drive the two support blocks 55 to move inward or outward at the same time. The support block 55 is slidably connected to the outside of the locking block 59. The locking block 59 makes the outside of the support block 55 lock into the inside of the bearing seat 51 and limit its sliding range, ensuring that the support block 55 slides within a reasonable range. The top of the quick-connect socket 39 is supported on the outside of the driver 53, so that the connector 42 docks with the driver 53, ensuring that power can be smoothly transmitted from the connector 42 to the driver 53. Specifically, the locking mechanism 5 has two bearing seats 51, which provide mounting support for the driver 53 and the embossing roller 54. The sliders 52 on both sides of the two bearing seats 51 cooperate with the guide rail 33 to allow the bearing seats 51 to slide smoothly. The driver 53 on the side of the bearing seat 51 can directly drive the embossing roller 54 to rotate. The embossing roller 54 at the output end on the side of the driver 53 is a key component for embossing PVC sheets. Its surface texture determines the embossing effect. The support blocks 55 that are slidably connected on both sides inside the bearing seats 51 can extend out from the bearing seats 51 to enhance the stability after installation. The toothed plate 56 on the side of the two support blocks 55 that is close to each other cooperates with the transmission gear 58 to realize the sliding of the support blocks 55. The handle 57, which is rotatably connected inside the bearing housing 51, allows the operator to rotate the transmission gear 58. When the transmission gear 58 is rotated, it can drive the toothed plate 56 to move, thereby causing the support block 55 to slide. The locking blocks 59 on both sides of the bearing housing 51 can limit the sliding range of the support block 55 and prevent it from sliding out of the bearing housing 51. The transmission gear 58 is installed inside the two support blocks 55 on the side closest to each other to ensure accurate meshing with the toothed plate 56. The transmission gear 58 and the toothed plate 56 are meshed and connected to each other. When rotated, it can drive the two support blocks 55 to move inward or outward at the same time. The support block 55 is slidably connected to the outside of the locking block 59. The locking block 59 is engaged inside the bearing housing 51 and limits the sliding range to ensure that the sliding is within a reasonable range. The top of the quick-connect socket 39 is supported outside the driver 53, so that the connector 42 is connected to the driver 53 to ensure smooth power transmission.

[0022] By sliding the bearing seat 51 from one end of the guide rail 33 to the mounting groove 6, the sliders 52 on both sides of the bearing seat 51 are engaged with the outside of the guide rail 33. The cooperation between the sliders 52 and the guide rail 33 ensures the smoothness and precision of the sliding process of the bearing seat 51. When the bearing seat 51 is engaged with the inside of the mounting groove 6, the support plate 35 is rotated to the outside of the positioning groove 36, so that the positioning bead 38 is engaged with the outside of the support plate 35. Under the action of the return spring 37, the positioning bead 38 tightly holds the support plate 35, restricting the position of the bearing seat 51 inside the mounting groove 6, preventing it from sliding, and so that the driver 53 is engaged with the top of the quick-connect socket 39, ensuring that the power transmission channel is unobstructed. Specifically, the bearing housing 51 is slid from one end of the guide rail 33 into the mounting groove 6. The sliders 52 on both sides of the bearing housing 51 will then engage with the outside of the guide rail 33. The cooperation between the two ensures that the sliding process of the bearing housing 51 is smooth and precise. After the bearing housing 51 is engaged in the mounting groove 6, the support plate 35 is rotated to the outside of the positioning groove 36. The positioning bead 38 will then engage with the outside of the support plate 35. Under the action of the return spring 37, the positioning bead 38 tightly holds the support plate 35, thereby limiting the position of the bearing housing 51 in the mounting groove 6 and preventing it from sliding. At the same time, the driver 53 will engage with the top of the quick-connect socket 39, thereby ensuring that the power transmission channel is unobstructed.

[0023] Working principle: When replacing the embossing roller 54, first turn the handle 57 to drive the transmission gear 58 to rotate. Through the meshing action of the transmission gear 58 and the toothed plate 56, the support block 55 slides inward within the range limited by the locking block 59, releasing the additional fixation on the bearing seat 51. Then, rotate the support plate 35 to make it rotate around the rotating shaft 34. The positioning bead 38 is compressed by the support plate 35, compresses the return spring 37 and returns to the positioning groove 36, releasing the limitation on the support plate 35. Then, push the bearing seat 51 to make the slider 52 slide along the guide rail 33, moving the bearing seat 51 together with the driver 53 and the embossing roller 54 out of the mounting groove 6. At this time, the driver 53 is separated from the quick-connect socket 39, the power transmitted by the connector 42 is interrupted, and the disassembly of the old embossing roller 54 is completed.

[0024] When installing the new embossing roller 54, the new locking mechanism 5 is slid into the mounting groove 6 along the guide rail 33 via the slider 52, so that the bearing seat 51 is engaged in the mounting groove 6. The support plate 35 is rotated to the outside of the positioning groove 36, and the positioning bead 38 pops out under the elastic force of the return spring 37 and engages with the outside of the support plate 35, restricting the position of the bearing seat 51. At the same time, the driver 53 is engaged with the top of the quick connector 39. The handle 57 is rotated in the opposite direction to make the support block 55 slide outward, enhancing the stability of the bearing seat 51, and completing the installation of the new embossing roller 54.

[0025] When the drive unit 41 is started, power is transmitted to the quick-connect socket 39 through the connector 42, and then from the quick-connect socket 39 to the driver 53. The driver 53 drives the embossing roller 54 to rotate. The PVC sheet passes through the embossing roller 54 with the auxiliary support of the fixed roller in the fixed roller groove 32. The embossing operation is completed under the action of the surface texture of the embossing roller 54. Throughout the process, the support frame 1 and the vertical frame 2 provide stable support for each component. The support frame 31 ensures the stability of the quick-connect socket 39 and ensures smooth power transmission.
