Description

Technical Field

[0001] This utility model relates to the technical field of PVC plastic flooring production equipment, specifically a synchronous conveying and positioning device for PVC plastic flooring production. Background Technology

[0002] In the production of PVC plastic flooring, conveying is a crucial link connecting various processes. From substrate calendering to surface treatment and cutting, the orderly flow of flooring is achieved through conveying equipment. Stable conveying ensures the consistent position of the flooring at each processing stage, providing a foundation for subsequent precise processing, and contributing to a smooth and efficient production process. It is an indispensable part of the large-scale production of PVC plastic flooring.

[0003] Utility model patent CN221937793U discloses a surface printing device for processing plastic flooring. This device includes a worktable with a conveyor belt at its upper end. A printing frame is fixedly connected to the other side of the worktable's top. Pneumatic telescopic rods are fixedly connected to both ends of the printing frame's top. The output end of the pneumatic telescopic rod is compressed into the printing frame and fixedly connected to a printing machine body. A printing roller is rotatably connected to the bottom of the printing machine body. Through a centralizing component, a servo motor drives the rotation of the positive and negative threaded rods, causing the threaded blocks to move and slide the centralizing plate until the gap between them is slightly larger than the width of the plastic flooring. This ensures that the subsequent plastic flooring, after passing through the centralizing plate, is positioned on the transverse central axis of the conveyor belt. This prevents plastic flooring of different widths from shifting on the conveyor belt, affecting the accuracy and aesthetics of subsequent printing and improving its applicability.

[0004] The surface printing device for processing plastic flooring centers the plastic flooring by clamping it with a centering plate. Although the inner wall of the centering plate is equipped with centering wheels to reduce friction, the centering wheels can only reduce the contact friction between the plastic flooring and the centering plate. They cannot avoid the relative friction between the plastic flooring and the conveyor belt surface when the plastic flooring is clamped. When the plastic flooring is released from the clamp, it is easy for the plastic flooring to become skewed again due to the slight vibration or belt deviation during the conveyor belt transport process, which will affect subsequent processing. In view of this, we propose a synchronous conveying and positioning device for PVC plastic flooring production. Utility Model Content

[0005] The purpose of this invention is to provide a synchronous conveying and positioning device for the production of PVC plastic flooring, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A synchronous conveying and positioning device for PVC plastic flooring production includes a conveyor seat, on which a conveyor belt for conveying PVC plastic flooring is installed. Seat plates are fixed at the left and right end faces of the conveyor seat. Between the two seat plates, there is an alignment mechanism for aligning the PVC plastic flooring and a top surface pressing mechanism for pressing the PVC plastic flooring against the surface of the conveyor belt. The number of alignment mechanisms is two, and they are symmetrically distributed on the left and right sides with the conveyor belt as the center. The alignment mechanism includes a pusher that is attached to the top surface of the conveyor belt and parallel to the side end face of the conveyor seat, and several alignment cylinders installed at the tail end of the pusher. Several rollers are rotatably connected at the first end face of the pusher. The alignment cylinders are installed on the outer end face of the seat plate. The alignment cylinders push the pusher toward the PVC plastic floor and make the rollers abut against the side edge of the PVC plastic floor. The top surface pressing mechanism includes a fixed rod placed horizontally between two seat plates and a swing rod rotatably connected to the fixed rod. The end of the swing rod is rotatably connected to a stop wheel, which abuts against the top surface of the conveyor belt. When the PVC plastic flooring is conveyed to the stop wheel by the conveyor belt, the stop wheel can roll to the top surface of the PVC plastic flooring and press the PVC plastic flooring against the top surface of the conveyor belt.

[0007] Preferably, an installation groove is provided on the first end face of the push base along its length direction, and the roller is vertically rotatably connected in the installation groove. Several rollers are evenly spaced in the installation groove along the length direction of the installation groove, and the outermost end of the roller protrudes from the first end face of the push base. In this setup, the mounting groove can fix the position of the rollers, and the evenly distributed rollers ensure that the force on the side of the floor is uniform. The rolling contact can reduce friction and avoid damage to the edge of the floor.

[0008] Preferably, a pair of guide rods are fixed to the tail end face of the push base, and both guide rods pass through the corresponding base plate and are slidably connected to the base plate; In this configuration, the guide rod restricts the direction of the pusher's movement, preventing it from shifting or tilting, and ensuring that it moves in a direction parallel to the side end face of the conveyor seat.

[0009] Preferably, a limiting screw is fixed at the middle position of the tail end face of the push seat. The limiting screw passes through the corresponding seat plate, which has a through hole for the limiting screw to pass through. Two adjusting bolts are threaded to the end of the limiting screw. The adjusting bolts are located on the outside of the seat plate, and the size of the adjusting bolts is larger than the diameter of the through hole. By adjusting the position of the two adjusting bolts on the limiting screw, the distance that the push seat moves toward the PVC plastic floor can be limited. In this setting, the limit screw and the adjusting bolt work together to adjust the maximum pushing distance of the pusher according to the width of the floor, avoiding excessive compression of the floor and adapting to the positioning needs of different floor sizes.

[0010] Preferably, a rotating sleeve is fixed to the first end of the swing arm, and the rotating sleeve is sleeved on the outside of the fixed arm and rotatably connected to the fixed arm; Preferably, a pair of retaining rings are fixed on the fixed rod, and the rotating sleeve is restricted between the two retaining rings; In these two settings, the rotating sleeve reduces the rotational friction between the swing rod and the fixed rod, and the retaining ring restricts the axial sliding of the rotating sleeve, ensuring that the abutment wheel is aligned with the centerline area of ​​the conveyor belt.

[0011] Preferably, a plug rod is fixed to the top of the swing rod, and several counterweight discs are sleeved on the plug rod; In this setup, the insert provides an installation position for the counterweight disc. Adding or removing the counterweight disc can adjust the clamping force of the abutment roller, adapting to flooring of different thicknesses or hardness.

[0012] Preferably, clearance grooves are provided on both the left and right edges of the top surface of the conveyor seat, and the positions of the clearance grooves correspond to the positions of the push seat. The clearance grooves are used to avoid the movement of the push seat. In this setting, the clearance groove can prevent interference between the pusher and the conveyor when the pusher moves laterally, ensuring the complete stroke of the pusher.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This synchronous conveying and positioning device for PVC flooring production uses rollers in the alignment mechanism to abut against the side edge of the PVC flooring. The rollers roll synchronously with the PVC flooring during conveying, further reducing the frictional resistance at the side edge of the PVC flooring. Simultaneously, the abutment rollers of the top surface pressing mechanism continuously press against the top surface of the PVC flooring, ensuring that the PVC flooring remains in contact with the conveyor belt surface throughout the alignment and conveying process, preventing relative friction between the two. At the same time, the top surface pressing mechanism provides continuous limiting guidance along the conveying path of the PVC flooring. Even after the initial alignment of the PVC flooring, continuous contact and limiting can reduce the possibility of it tilting again after detaching from the single clamping structure, ensuring the positioning stability of subsequent processing steps.

Example

[0017] Please see Figures 1-3 A synchronous conveying and positioning device for PVC plastic flooring production includes a conveyor seat 100, on which a conveyor belt 110 for conveying PVC plastic flooring is installed. Seat plates 120 are fixed to the left and right end faces of the conveyor seat 100. A positioning mechanism 200 for positioning the PVC plastic flooring is arranged between the two seat plates 120. There are two positioning mechanisms 200, symmetrically distributed left and right with the conveyor belt 110 as the center. Each positioning mechanism 200 includes a pusher 210 attached to the top surface of the conveyor belt 110 and parallel to the side end face of the conveyor seat 100, and several positioning cylinders 220 installed at the tail end of the pusher 210. The positioning cylinders 220 provide stable thrust, ensuring that the pusher 210 moves accurately toward the PVC plastic flooring, providing the power basis for subsequent positioning actions.

[0018] like Figure 3As shown, in this utility model, a plurality of rollers 212 are rotatably connected to the first end face of the push base 210. An installation groove 211 is provided on the first end face of the push base 210 along its length direction. The installation groove 211 can limit and fix the rollers 212 to ensure that the position of the rollers 212 is stable during rotation. The rollers 212 are vertically rotatably connected in the installation groove 211. The plurality of rollers 212 are evenly spaced in the installation groove 211 along the length direction of the installation groove 211. The evenly arranged rollers 212 can make the side of the PVC plastic flooring evenly stressed, avoiding excessive local stress that could damage the edge of the flooring. The outermost end of the rollers 212 protrudes from the first end face of the push base 210. At the same time, the rollers 212 roll synchronously with the flooring conveyor, which can reduce the frictional resistance between the side of the flooring and the push base 210.

[0019] like Figure 1 and Figure 3 As shown, specifically, the positioning cylinder 220 is mounted on the outer end face of the seat plate 120. The seat plate 120 provides a stable mounting support for the positioning cylinder 220, ensuring that the cylinder thrust can be effectively transmitted to the push seat 210. The positioning cylinder 220 pushes the push seat 210 toward the PVC plastic floor and causes the roller 212 to abut against the side edge of the PVC plastic floor. When the roller 212 abuts against the side edge of the floor, it can guide the floor to move along the centerline of the conveyor belt 110 through rolling action, thus achieving the positioning effect. Clearance grooves 130 are provided on both the left and right edges of the top surface of the conveyor seat 100. The positions of the clearance grooves 130 correspond to the positions of the push seat 210. The clearance grooves 130 are used to avoid the movement of the push seat 210, preventing interference between the push seat 210 and the conveyor seat 100 during lateral movement and ensuring the complete stroke of the push seat 210.

[0020] like Figure 1 and Figure 3 As shown, a pair of guide rods 213 are fixed to the tail end face of the push seat 210. Both guide rods 213 pass through the corresponding seat plate 120 and are slidably connected to the seat plate 120. The guide rods 213 can limit the movement direction of the push seat 210, prevent the push seat 210 from deviating or tilting under the push of the cylinder, and ensure that the push seat 210 always moves in a direction parallel to the side end face of the conveyor seat 100.

[0021] like Figure 3As shown, a limiting screw 214 is fixed at the middle position of the tail end face of the pusher 210. The limiting screw 214 passes through the corresponding base plate 120. The base plate 120 has a through hole for the limiting screw 214 to pass through. Two adjusting bolts 215 are threaded to the end of the limiting screw 214. The adjusting bolts 215 are located on the outside of the base plate 120. The size of the adjusting bolts 215 is larger than the diameter of the through hole. By adjusting the position of the two adjusting bolts 215 on the limiting screw 214, the distance that the pusher 210 moves toward the PVC plastic floor can be limited. The limiting screw 214 and the adjusting bolts 215 cooperate to adjust the maximum pushing distance of the pusher 210 according to the width of the PVC plastic floor, so as to avoid the pusher 210 from excessively squeezing the floor and causing deformation, and at the same time adapting to the positioning needs of different specifications of floor.

[0022] In this embodiment, the synchronous conveying and positioning device for PVC plastic flooring production operates as follows: First, based on the width of the PVC plastic flooring to be positioned, the positions of the two adjusting bolts 215 on the limiting screw 214 are adjusted to determine the maximum advancing distance of the pusher 210. Then, the PVC plastic flooring is placed on the conveyor belt 110, which starts and drives the flooring towards the positioning mechanism 200. Next, the positioning cylinder 220 is vented, pushing the pusher 210 along the guide rod 213 towards the flooring until the roller 212 abuts against the side edge of the flooring. During this process, the clearance groove 130 avoids the movement of the pusher 210 to prevent interference. Finally, the roller 212 rolls synchronously with the flooring, guiding the flooring to move along the centerline of the conveyor belt 110. After positioning is completed, the positioning cylinder 220 drives the pusher 210 to reset, waiting for the next flooring to be conveyed. Example

[0023] Because the PVC plastic flooring is clamped by the two positioning mechanisms 200 during positioning, it is prone to friction between the PVC plastic flooring and the conveyor belt 110. This causes the PVC plastic flooring to deviate again on the conveyor belt 110 when it is released by the positioning mechanisms 200. Therefore, in order to ensure that the PVC plastic flooring always adheres to the conveyor belt 110, such as... Figure 1 and Figure 4As shown, a top surface pressing mechanism 300 for pressing PVC plastic flooring against the surface of the conveyor belt 110 is also provided between the two seat plates 120. The top surface pressing mechanism 300 includes a fixed rod 310 placed horizontally between the two seat plates 120 and a swing rod 320 rotatably connected to the fixed rod 310. The fixed rod 310 provides rotational support for the swing rod 320, ensuring that the swing rod 320 can rotate flexibly around the fixed rod 310 to adapt to PVC plastic flooring of different thicknesses. The end of the swing arm 320 is rotatably connected to a stop wheel 321. The stop wheel 321 makes rolling contact with the top surface of the floor, which can avoid scratching the floor surface. The stop wheel 321 abuts against the top surface of the conveyor belt 110. When the PVC plastic floor is conveyed by the conveyor belt 110 to the stop wheel 321, the stop wheel 321 can roll to the top surface of the PVC plastic floor and press the PVC plastic floor against the top surface of the conveyor belt 110. At the same time, the continuous pressing force can ensure that the floor and the surface of the conveyor belt 110 are tightly attached to each other, preventing relative friction between the two and reducing the possibility of the floor tilting again after it is separated from the positioning mechanism 200.

[0024] In this embodiment, a rotating sleeve 322 is fixed to the first end of the swing rod 320. The rotating sleeve 322 is sleeved on the outside of the fixed rod 310 and rotatably connected to the fixed rod 310. The rotating sleeve 322 can reduce the rotational friction between the swing rod 320 and the fixed rod 310, making the swinging motion of the swing rod 320 smoother as it moves with the floor conveyor. A pair of retaining rings 311 are fixed on the fixed rod 310. The rotating sleeve 322 is restricted between the two retaining rings 311. The retaining rings 311 can axially limit the rotating sleeve 322, preventing the rotating sleeve 322 from sliding along the length of the fixed rod 310, and ensuring that the abutment wheel 321 is always aligned with the centerline area of ​​the conveyor belt 110.

[0025] Specifically, a plug rod 323 is fixed to the top of the swing rod 320. The plug rod 323 provides an installation carrier for the counterweight discs 324. Several counterweight discs 324 are sleeved on the plug rod 323. The number of counterweight discs 324 can be freely increased or decreased. By increasing or decreasing the number of counterweight discs 324, the clamping force of the abutment roller 321 on the top surface of the floor can be adjusted to adapt to PVC plastic flooring of different thicknesses or hardnesses. This avoids insufficient clamping force leading to poor adhesion, or excessive clamping force leading to obstruction of flooring transport.

[0026] In this embodiment, the synchronous conveying and positioning device for PVC plastic flooring production first determines the clamping force of the abutment roller 321 by fitting an appropriate amount of counterweight disc 324 onto the insertion rod 323 according to the thickness and hardness of the PVC plastic flooring. Then, the conveyor belt 110 starts, driving the PVC plastic flooring towards the alignment mechanism 200 and the top surface pressing mechanism 300. When the flooring contacts the abutment roller 321, it pushes the abutment roller 321 to drive the swing rod 320 to rotate around the fixed rod 310, and the rotating sleeve 322 rotates accordingly. The retaining ring 311... The axial position of the rotating sleeve 322 is restricted; then, the positioning cylinder 220 of the positioning mechanism 200 pushes the pusher 210 to move, so that the roller 212 abuts against the side of the floor for positioning. At the same time, the abutment roller 321, under the gravity of the counterweight plate 324, continues to press against the top surface of the floor to ensure that the floor and the conveyor belt 110 are in close contact. Finally, after the floor is positioned, it continues to be conveyed with the conveyor belt 110. The abutment roller 321 rolls with the floor and remains in a pressing state until the floor is separated from the top surface pressing mechanism 300, effectively reducing the possibility of the floor tilting again.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
