Description

Technical Field

[0001] This invention belongs to the technical field of conical roller conveyor components, and specifically relates to a conical conveyor component for a roller coating machine. Background Technology

[0002] A roller coating machine is an industrial piece of equipment used for surface treatment. It primarily uses rollers to evenly apply coatings, adhesives, or other functional liquids to the surface of substrates such as sheets, rolls, or rolls. It is widely used in industries such as building materials, furniture, automobile manufacturing, electronics, and packaging, and is one of the key pieces of equipment for achieving efficient and precise coating processes.

[0003] To prevent substrate misalignment, conical roller sets are typically installed on roller coating machines to achieve material centering and automatic correction. These conical roller sets primarily utilize the geometric characteristics of a cone (its diameter gradually changes along the axial direction). When sheet materials, rolls, or other workpieces pass through, the two edges experience different linear velocity differences due to contact with areas of varying diameters. This difference ensures the workpiece consistently moves towards the center, guaranteeing stable operation along the set trajectory.

[0004] Because the tapered roller is in line contact with the plate, after long-term high-load operation, the tapered generatrix will deform due to friction (such as concavity in the middle or sharpening of the edges), which will damage the original geometric accuracy and cause problems such as workpiece deviation and increased vibration. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing a conical conveyor assembly for a roller coating machine, thereby solving the technical problems in the prior art.

[0006] The objective of this invention can be achieved through the following technical solution: a tapered conveyor assembly for a roller coating machine, comprising a worktable, wherein a coating assembly and a transmission assembly are sequentially installed on the worktable from the inlet end to the outlet end; a power box is installed on the worktable, driving the coating assembly; a top box is installed on the top of the worktable; the transmission assembly includes a side plate, which is connected to a guide sleeve on the transmission box via a guide rod; a tapered roller assembly is installed on the transmission box; the tapered roller assembly includes a cylinder and a tapered roller component; the cylinder is installed inside the transmission box; the tapered roller component is rotatably installed on the inner side wall of the transmission box; a transmission sleeve is fixedly installed on the tapered roller component; the cylinder is connected to a transfer plate inside the tapered roller component via a piston rod passing through the transmission sleeve; a connecting rod is slidably installed on the transfer plate; an electromagnetic chuck is installed at one end of the connecting rod, which is connected to a magnetic ring on the transfer plate; a push sleeve is installed at the other end of the connecting rod, which is connected to a support ring via a push rod.

[0007] As a further optimization or improvement of this solution, an arc-shaped groove is opened inside the supporting ring sleeve, the push rod slides in the arc-shaped groove, a threaded ball groove is opened inside the arc-shaped groove, a ball is installed on the push rod, the ball slides in cooperation with the threaded ball groove, and the push rod is connected to the inner wall of the arc-shaped groove by a spring.

[0008] As a further optimization or improvement of this solution, an annular groove is opened inside the supporting ring sleeve, an inlet hole is opened on the outer side of the supporting ring sleeve, and a drain hole is opened on the inner side. The inlet hole and the drain hole are connected to the annular groove. A push ring is installed on the push rod, and a hollow ring plug is slidably installed inside the annular groove. The push ring is located inside the push ring, and the outer and inner through holes of the hollow ring plug are arranged alternately. The through holes on the push ring coincide with the outer through holes of the hollow ring plug.

[0009] As a further optimization or improvement of this solution, a transmission rod is installed on the side plate. The transmission rod is driven by a motor built into the power box. A transmission component is installed on the transmission box. The transmission rod and the transmission component are connected in transmission. A transmission wheel one and a transmission wheel two are installed on the transmission sleeve. The transmission wheel one and the transmission wheel two on each group of conical rollers in the conical roller group are alternately connected by a chain. The chain teeth on the transmission component drive the conical roller group to rotate by connecting the transmission wheel one to the chain.

[0010] As a further optimization or improvement of this solution, a clamping plate is installed on the transmission box, and a transmission motor is installed on the outer wall of the side plate. The transmission motor drives the transmission belt to rotate, and the clamping plate holds the transmission belt.

[0011] As a further optimization or improvement of this solution, the coating assembly includes a feed roller group and a coating roller group, with the feed roller group located at the feed end and a baffle installed between the feed roller group and the coating roller group.

[0012] As a further optimization or improvement of this solution, a hopper and a material box are installed inside the workbench. The hopper is located at the bottom of the coating component and the transmission component, and the hopper is connected to the material box. A stirring component is also installed inside the workbench to stir the coating inside the material box.

[0013] The beneficial effects of this invention are:

[0014] (1) The present invention uses a cylinder to push the piston rod to move, and the piston rod pushes the corresponding electromagnetic chuck and connecting rod to move through the adapter plate. The push sleeve pushes out the supporting ring sleeve through the push rod. The supporting ring sleeve supports the bottom of the substrate, increases the contact area between the conical roller group and the substrate, greatly reduces the pressure of the substrate on the conical surface, and thus avoids contour deformation and problems such as workpiece deviation.

[0015] (2) When the pusher pushes out the support ring sleeve through the pusher rod, the pusher rod on the pusher sleeve slides inside the arc groove and compresses the spring. The ball on the pusher rod cooperates with the threaded ball groove in the arc groove, and the pusher sleeve drives the support ring sleeve to rotate with stored force. When the substrate slips due to the thin film layer formed on the surface of the tapered roller and the support ring sleeve, the pusher rod is reset under the action of the spring. The pusher rod drives the pusher ring to pull the hollow ring plug to move. The hollow ring plug forms a negative pressure inside the ring groove, which in turn draws the coating film on the outer wall of the support ring sleeve into the ring groove through the liquid inlet hole, restoring the friction coefficient of the contact surface between the support ring sleeve and the substrate.

[0016] (3) The present invention uses spring to store and rebound, and the spring drives the supporting ring to accelerate the movement, and the supporting ring compensates for the displacement of the substrate; with the cooperation of the ball and the threaded ball groove, the spring drives the supporting ring to move outward, and the supporting ring pushes the substrate to prevent the substrate from shifting to the slipping part.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] See Figures 1-11 A tapered conveyor assembly for a roller coating machine includes a worktable 1. A coating assembly 2 and a transmission assembly 8 are sequentially mounted on the worktable 1 from the inlet to the outlet. A power box 3 is mounted on the worktable 1, driving the coating assembly 2. A top box 4 is mounted on the top of the worktable 1. The transmission assembly 8 includes a side plate 801, which is connected to a guide sleeve 807 on the transmission box 803 via a guide rod 802. A tapered roller assembly 9 is mounted on the transmission box 803. The tapered roller assembly 9 includes a cylinder 901 and a tapered roller component 904. The cylinder 901 is mounted on the transmission assembly 803. Inside the housing 803, a conical roller 904 is rotatably mounted on the inner wall of the transmission housing 803. A transmission sleeve 903 is fixedly mounted on the conical roller 904. A cylinder 901 is connected to a transition plate 908 inside the conical roller 904 via a piston rod 902 passing through the transmission sleeve 903. A connecting rod 907 is slidably mounted on the transition plate 908. An electromagnetic chuck 909 is mounted on one end of the connecting rod 907 and is connected to a magnetic ring 910 on the transition plate 908. A push sleeve 906 is mounted on the other end of the connecting rod 907 and is connected to a support ring sleeve 905 via a push rod 911.

[0036] Specifically, the supporting ring 905 has an arc-shaped groove 918 inside, the push rod 911 slides in the arc-shaped groove 918, the arc-shaped groove 918 has a threaded ball groove 919 inside, the push rod 911 is mounted with a ball 912, the ball 912 slides in conjunction with the threaded ball groove 919, and the push rod 911 is connected to the inner wall of the arc-shaped groove 918 by a spring 920.

[0037] Specifically, the coating assembly 2 includes a feed roller group 201 and a coating roller group 203. The feed roller group 201 is located at the feed end, and a baffle 202 is installed between the feed roller group 201 and the coating roller group 203.

[0038] It should be noted that the substrate is fed into the present invention through the feed roller group 201, and after being coated by the coating roller group 203, it is sent out through the conical roller group 9; the conical roller group 9 realizes the function of centering and automatically correcting the substrate.

[0039] Considering the small contact area between the conical roller assembly 9 and the substrate, and the problem of contour deformation of the conical generatrix due to friction after long-term high-load operation, this invention uses a cylinder 901 to push a piston rod 902 to move. The piston rod 902, through an adapter plate 908, pushes the corresponding electromagnetic chuck 909 and connecting rod 907 to move. See [link to relevant documentation]. Figures 9-11 The push sleeve 906 pushes out the support ring sleeve 905 through the push rod 911. The support ring sleeve 905 supports the bottom of the substrate, increases the contact area between the conical roller group 9 and the substrate, greatly reduces the pressure of the substrate on the conical surface, and thus avoids contour deformation and problems such as workpiece deviation.

[0040] It should be noted that the connecting rod 907 is magnetically connected to the magnetic ring 910 on the adapter plate 908 via the electromagnetic chuck 909. When the corresponding push sleeve 906 and support ring sleeve 905 need to be pushed, the corresponding electromagnetic chuck 909 is energized, connecting the adapter plate 908 to the electromagnetic chuck 909. The other electromagnetic chucks 909 are de-energized.

[0041] See Figures 7-12 The supporting ring 905 has an annular groove 917 inside, an inlet hole 913 on the outer side and a drain hole 914 on the inner side. The inlet hole 913 and the drain hole 914 are connected to the annular groove 917. A push ring 916 is installed on the push rod 911. A hollow ring plug 915 is slidably installed inside the annular groove 917. The push ring 916 is located inside the push ring 916. The outer through holes and inner through holes of the hollow ring plug 915 are arranged alternately. The through holes on the push ring 916 coincide with the outer through holes of the hollow ring plug 915.

[0042] It should be noted that during the roll coating process, there are some coatings containing lubricating substances. The coating forms a low-friction thin film layer on the conical roller group 9, which reduces the friction coefficient of the steel-to-steel contact surface and makes it easy for the substrate on the conical roller group 9 to slip.

[0043] When the pusher sleeve 906 pushes out the support ring sleeve 905 via the push rod 911, the support ring sleeve 905 first contacts the substrate. Due to the obstruction of the substrate, the push rod 911 on the pusher sleeve 906 slides inside the arc-shaped groove 918 and compresses the spring 920. Through the engagement of the ball 912 on the push rod 911 with the threaded ball groove 919 in the arc-shaped groove 918, the pusher sleeve 906 drives the support ring sleeve 905 to rotate. After the support ring sleeve 905 rotates a certain angle, the pusher sleeve 906 pushes the support ring sleeve 905 to move synchronously via the push rod 911, causing one inclined surface of the support ring sleeve 905 to lift the substrate, thus supporting the substrate. As the conical roller 904 rotates, it drives the pusher sleeve 906 and the support ring sleeve 905 to rotate synchronously, thereby conveying the substrate.

[0044] When the substrate slips due to the thin film layer formed on the surfaces of the conical roller 904 and the supporting ring 905, the coefficient of friction between the supporting ring 905 and the substrate decreases, and the push rod 911 returns to its original position under the action of the spring 920. (See also...) Figure 9 and Figure 12 The push rod 911 drives the push ring 916 to pull the hollow ring plug 915 to move. Through the interlacing of the push ring 916 and the through hole on the inner side of the hollow ring plug 915, the hollow ring plug 915 forms a negative pressure in the ring groove 917, thereby drawing the coating film on the outer wall of the supporting ring sleeve 905 into the ring groove 917 through the liquid inlet hole 913, restoring the coefficient of friction between the supporting ring sleeve 905 and the substrate contact surface.

[0045] It should be noted that when the substrate slips, the displacement of the slipped part of the substrate decreases, causing the substrate to shift towards the slipped part. Based on this, as the spring 920 stores its force and rebounds, the spring 920 drives the support ring 905 to accelerate, and the support ring 905 compensates for the displacement of the substrate. With the cooperation of the ball 912 and the threaded ball groove 919, the spring 920 drives the support ring 905 to move outward, and the support ring 905 pushes the substrate to prevent the substrate from shifting towards the slipped part.

[0046] See Figures 4-7 A transmission rod 806 is installed on the side plate 801. The transmission rod 806 is driven by a motor built into the power box 3. A transmission component 809 is installed on the transmission box 803. The transmission rod 806 is connected to the transmission component 809. A transmission wheel 810 and a transmission wheel 811 are installed on the transmission sleeve 903. The transmission wheel 810 and the transmission wheel 811 on each group of conical rollers in the conical roller group 9 are alternately connected by a chain. The chain teeth on the transmission component 809 drive the conical roller group 9 to rotate by connecting the transmission wheel 810 to the chain.

[0047] Specifically, a clamping plate 808 is installed on the transmission box 803, and a transmission motor 804 is installed on the outer wall of the side plate 801. The transmission motor 804 drives the transmission belt 805 to rotate, and the clamping plate 808 clamps the transmission belt 805.

[0048] It should be noted that the conical roller group 9 is adjusted via the transmission assembly 8, and the adjustment method is as follows (see below). Figures 4-5 The transmission belt 805 is driven by a transmission motor 804. The transmission belt 805 is connected to the transmission box 803 via a clamping plate 808 at the bottom. The transmission belt 805 drives the transmission box 803 to move relative to the guide rod 802. When it is necessary to drive the conical roller assembly 9 to rotate, the motor inside the power box 3 drives the transmission rod 806 to rotate. The transmission rod 806 is connected to the transmission component 809 at the bottom of the transmission box 803, which in turn drives the sprocket on the transmission component 809 to rotate. The sprocket drives the transmission sleeve 903 and the conical roller assembly 904 to rotate via a chain.

[0049] It should be noted that the connecting rod 907, push sleeve 906 and support ring sleeve 905 of the present invention can be set as a single unit. The support ring sleeve 905 and push sleeve 906 are pushed to support the substrate by means of fixed connection between the connecting rod 907 and the adapter plate 908.

[0050] See Figures 2-3 The workbench 1 is equipped with a hopper 5 and a material box 6. The hopper 5 is located at the bottom of the coating component 2 and the transmission component 8. The hopper 5 is connected to the material box 6. The workbench 1 is also equipped with a stirring component 7, which stirs the coating inside the material box 6.

[0051] It should be noted that during the coating operation, excess paint is collected in the tank 6 through the hopper 5, which facilitates the recycling of the paint; the stirring component 7 continuously stirs the paint inside the tank 6 to prevent the paint from solidifying.

[0052] The implementation principle of this invention is as follows:

[0053] The substrate is fed into the roller coating machine through the feed roller group 201, and after being coated by the paint roller group 203, it is sent out through the conical roller group 9. The conical roller group 9 achieves the function of centering and positioning the substrate through the geometric characteristics of the cone.

[0054] Considering the small contact area between the conical roller assembly 9 and the substrate, and the problem of contour deformation of the conical generatrix due to friction after long-term high-load operation, this invention uses a cylinder 901 to push a piston rod 902 to move. The piston rod 902, through an adapter plate 908, pushes the corresponding electromagnetic chuck 909 and connecting rod 907 to move. See [link to relevant documentation]. Figures 9-11 The push sleeve 906 pushes out the support ring sleeve 905 through the push rod 911. The support ring sleeve 905 supports the bottom of the substrate, increases the contact area between the conical roller group 9 and the substrate, greatly reduces the pressure of the substrate on the conical surface, and thus avoids contour deformation and problems such as workpiece deviation.

[0055] It should be noted that during the roll coating process, there are some coatings containing lubricating substances. The coating forms a low-friction thin film layer on the conical roller group 9, which reduces the friction coefficient of the steel-to-steel contact surface and makes it easy for the substrate on the conical roller group 9 to slip.

[0056] When the pusher sleeve 906 pushes out the support ring sleeve 905 via the push rod 911, the support ring sleeve 905 first contacts the substrate. Due to the obstruction of the substrate, the push rod 911 on the pusher sleeve 906 slides inside the arc-shaped groove 918 and compresses the spring 920. Through the engagement of the ball 912 on the push rod 911 with the threaded ball groove 919 in the arc-shaped groove 918, the pusher sleeve 906 drives the support ring sleeve 905 to rotate. After the support ring sleeve 905 rotates a certain angle, the pusher sleeve 906 pushes the support ring sleeve 905 to move synchronously via the push rod 911, causing one inclined surface of the support ring sleeve 905 to lift the substrate, thus supporting the substrate. As the conical roller 904 rotates, it drives the pusher sleeve 906 and the support ring sleeve 905 to rotate synchronously, thereby conveying the substrate.

[0057] When the substrate slips due to the thin film layer formed on the surfaces of the conical roller 904 and the supporting ring 905, the coefficient of friction between the supporting ring 905 and the substrate decreases, and the push rod 911 returns to its original position under the action of the spring 920. (See also...) Figure 9 and Figure 12 The push rod 911 drives the push ring 916 to pull the hollow ring plug 915 to move. Through the interlacing of the push ring 916 and the through hole on the inner side of the hollow ring plug 915, the hollow ring plug 915 forms a negative pressure inside the ring groove 917, thereby drawing the coating film on the outer wall of the supporting ring sleeve 905 into the ring groove 917 through the liquid inlet hole 913, restoring the coefficient of friction between the supporting ring sleeve 905 and the substrate contact surface.

[0058] It should be noted that when the substrate slips, the displacement of the slipped part of the substrate decreases, causing the substrate to shift towards the slipped part. Based on this, as the spring 920 stores its force and rebounds, the spring 920 drives the support ring 905 to accelerate, and the support ring 905 compensates for the displacement of the substrate. With the cooperation of the ball 912 and the threaded ball groove 919, the spring 920 drives the support ring 905 to move outward, and the support ring 905 pushes the substrate to prevent the substrate from shifting towards the slipped part.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
