Description

Technical Field

[0001] The utility model relates to the field of glassware preparation, in particular to an adjustable coating device for glassware processing. Background Art

[0002] During the production process of glass products, they are generally coated on the surface. Due to the type of coating, the glass products can generally increase their gloss, oxidation resistance, acid and alkali resistance, and UV resistance. After the paint surface is coated, the paint surface can also be isolated from the outside world, playing a good protective role.

[0003] When coating glassware, especially glassware with complex shapes, most of them use the immersion coating method, that is, immersing the glassware completely in the coating solution. During immersion coating, it is necessary to use equipment to transfer it to a pool of coating solution for immersion. Since the structures and shapes of each glassware are different, and glass is fragile, it is difficult to control when clamping, and it is too expensive to design fixtures for different products. Utility Model Content

[0004] In order to solve the technical problem that it is difficult to uniformly clamp different glasswares when coating them, the utility model provides an adjustable coating device for glassware processing.

[0005] The utility model is implemented by the following technical scheme: an adjustable coating device for glassware processing, comprising a drum, both ends of which are fixedly connected to fixed shafts, a retaining frame is arranged outside the fixed shaft, and the drum is also provided with:

[0006] A driving mechanism, the driving mechanism is arranged on both sides of the drum, and the driving mechanism is used to drive the drum to reciprocate;

[0007] A clamping mechanism, wherein the clamping mechanism is arranged inside the drum and one end of the clamping mechanism extends out of the drum, and the clamping mechanism is provided with two groups, and the two groups of the clamping mechanisms are arranged up and down;

[0008] The clamping mechanism comprises a clamping plate and a slider, wherein the slider is arranged inside the clamping plate and is used to push the clamping plate to move and clamp;

[0009] The drum is also provided with:

[0010] A bow-shaped member is used to connect the two groups of the clamping mechanisms, and an inner hydraulic rod is also arranged on one side of the bow-shaped member.

[0011] Through the above technical scheme, the cooperation of the internal hydraulic rod and the bow-shaped member drives the upper and lower clamping mechanisms to operate, clamps the glassware, and then drives the roller to flip through the driving mechanism, so that the glassware enters the coating tank for immersion coating.

[0012] As a further improvement of the above solution, the outer side of the fixed shaft is rotatably connected to a limiting block via a plane bearing, and a corresponding limiting slot is provided on the retaining frame, and the limiting block is slidably installed in the limiting slot.

[0013] Through the above technical solution, the cooperation between the limiting block and the limiting slide groove provides guidance and limiting effects for the horizontal movement of the roller.

[0014] As a further improvement of the above solution, the driving mechanism includes:

[0015] A gear, wherein the gear is fixedly connected to the fixed shaft;

[0016] A rack, the rack is fixedly connected to the inner bottom of the retaining frame, and the gear and the rack are meshed;

[0017] A connecting block is rotatably connected to one end of the fixed shaft, and one side of the connecting block is connected to an external hydraulic rod.

[0018] Through the above technical solution, when the external hydraulic rod is extended, the connecting block is pushed to move, and then the drum rolls forward through the cooperation of the gear and the rack.

[0019] As a further improvement of the above solution, the clamping mechanism further includes:

[0020] A guide rod, wherein an oblong through hole is provided in the middle of the clamping plate, the guide rod is fixedly installed in the through hole, and the slider is movably sleeved on the guide rod;

[0021] A spring, wherein the spring is sleeved on the guide rod;

[0022] A clamping jaw, the clamping jaw being fixedly connected to one end of the clamping plate;

[0023] An oblique connecting rod, one end of which is rotatably mounted on the sliding block, and the other end of which is rotatably connected to one end of the bow member;

[0024] A guide plate is fixedly connected to one end of the clamping plate, and the guide plate and the clamping plate are installed obliquely.

[0025] As a further improvement of the above solution, one end of the guide plate extends out of the drum, and a plurality of threaded holes are provided on the guide plate. The threaded holes are threadedly connected to limit blocks, and a corresponding limit frame is fixedly connected to the outer wall of the drum.

[0026] Through the above technical solution, when the oblique connecting rod drives the slider to move, when it does not contact the glassware, due to the obstruction of the spring, the clamping plate can be pushed to move closer. After the clamping plate (clamping claw) contacts the glassware, if the oblique connecting rod continues to drive the slider to move, the spring begins to be compressed, especially for glassware with uneven thickness at the top and bottom, the upper and lower sets of clamping mechanisms can ensure clamping.

[0027] As a further improvement of the above solution, a support ring is sleeved on the outer side of the guide plate, and the support ring is fixedly connected to the inner wall of the drum.

[0028] Through the above technical solution, the supporting ring is used to support the clamping mechanism.

[0029] As a further improvement of the above solution, a conveyor is further provided on one side of the roller, and the external hydraulic rod is fixedly installed on the side of the conveyor.

[0030] Through the above technical solution, the conveyor is used to cooperate with the equipment to transport the glassware to be coated to the designated location.

[0031] The utility model drives the slider to move through the internal hydraulic rod and the bow-shaped member, and cooperates with the guide plate to make the clamping claws move forward while approaching each other until the glassware is clamped. When the glassware is uneven in thickness from top to bottom, one of the clamping claws first contacts the glassware. At this time, the slider moves along the guide rod to compress the spring, so that the clamping claw that first contacts the glassware stops moving, while the other clamping claw is not affected, until the two clamping claws cooperate to clamp the glassware, and finally the workpiece is immersed in the coating by the rotation of the roller.

[0032] The utility model can flexibly clamp different types of glassware without the need to set a separate clamping claw for each glassware. The cooperation of the limit block and the limit frame can prevent the clamping plate and the clamping claw from moving too far, resulting in excessive pressure on the glassware and causing damage to the glassware.

[0040] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0041] Please combine Figure 1 - Figure 5 The present embodiment is an adjustable coating device for glassware processing. First, the device needs to be used in conjunction with a conveyor 11 and a pool (not marked in the figure) carrying the coating liquid. First, the device needs to be set on one side of the conveyor 11, and the conveyor 11 transports the glassware to be coated to the designated position.

[0042] Specifically, an adjustable coating device for glassware processing includes a roller 1. First, fixed shafts 2 are fixedly connected at both ends of the roller 1. A limiting block 31 is rotatably connected to the fixed shaft 2 through a plane bearing. A retaining frame 3 for support is provided on both sides of the roller 1. A limiting slide groove 32 is provided in the retaining frame 3, and the limiting block 31 is slidably installed in the limiting slide groove 32.

[0043] Because the glassware on the conveyor 11 needs to be clamped and then transferred to the coating pool for immersion, a clamping mechanism 7 is provided inside the drum 1. Considering that the glassware may be slender, the clamping mechanism 7 is provided with two upper and lower groups. The two groups of clamping mechanisms 7 have the same structure. In order to connect the upper and lower groups of clamping mechanisms 7, an internal hydraulic rod 5 is fixedly installed in the drum 1, and the other end of the internal hydraulic rod 5 is connected to a bow 6, and the internal hydraulic rod 5 is connected to the middle part of the bow 6, and the two ends of the bow 6 are connected to the two groups of clamping mechanisms 7.

[0044] Specifically, the clamping mechanism 7 includes a clamping plate 71, a clamping claw 72 and an oblique connecting rod 77, that is, one end of the clamping plate 71 is fixedly connected to the clamping claw 72 by a screw, and the inner side of the clamping claw 72 is provided with a V-shaped groove for conveniently clamping glassware, and one end of the clamping plate 71 and the clamping claw 72 extend out of the drum 1 together, and an oblong through hole is opened in the middle of the clamping plate 71, and a guide rod 75 is fixedly connected in the through hole, and a slider 74 is movably sleeved on the guide rod 75, and a spring 76 is also sleeved on the guide rod 75;

[0045] One end of the oblique link 77 is rotatably connected to the slider 74 , and the other end is rotatably connected to one end of the bow member 6 .

[0046] Meanwhile, the other end of the clamping plate 71 is fixedly connected with a guide plate 73, which is installed obliquely between the guide plate 73 and the clamping plate 71, and one end of the guide plate 73 extends out of the drum 1. In order to facilitate the installation of the clamping mechanism 7, a support ring 10 is sleeved on the outer side of the guide plate 73, and the support ring 10 is fixedly connected to the inner wall of the drum 1. In addition, a plurality of threaded holes are opened at one end of the guide plate 73 away from the clamping plate 71, and the threaded inner holes are threadedly connected with the limit block 8, and the corresponding limit frame 9 is fixedly connected to the outer wall of the drum 1.

[0047] In summary, when the inner hydraulic rod 5 is controlled to extend, the bow 6 is pushed forward, and the bow 6 drives the slider 74 to move through the oblique connecting rod 77;

[0048] It should be noted that when the clamping claw 72 does not contact the glassware, the slider 74 is blocked by the spring 76, and the slider 74 will push the entire clamping plate 71 forward together through the spring 76. At this time, since the guide plate 73 and the clamping plate 71 are installed obliquely, when the guide plate 73 moves, it will also drive the two clamping plates 71 to move closer to the middle. At this time, the support ring 10 used for support can provide a limit and guide function for the movement of the guide plate 73;

[0049] When the clamp 72 contacts the glassware, especially the glassware with uneven thickness at the top and bottom, such as the glassware with thick lower part and thin upper part in the figure, the clamp 72 at the bottom will definitely contact the glassware first, while the clamp 72 at the top has not yet contacted the glassware. At this time, the bow 6 continues to move, and the clamp 71 and the clamp 72 at the bottom are blocked by the glassware and no longer move. At this time, the slider 74 will move along the guide rod 75, compressing the spring 76, while the clamp 71 and the clamp 72 at the top continue to move until the glassware is clamped.

[0050] Please combine Figure 6 In addition, after the glassware is clamped, it is necessary to transfer the glassware to the coating tank for immersion, so a driving mechanism 4 is also provided on both sides of the drum 1, and the driving mechanism 4 is used to drive the drum 1 to reciprocate. Specifically:

[0051] The driving mechanism 4 includes a gear 41, a rack 42, a connecting block 43 and an external hydraulic rod 44. First, the gear 41 is fixedly connected to the fixed shaft 2, and the rack 42 is fixedly connected to the inner bottom of the retaining frame 3, and the gear 41 and the rack 42 are kept in meshing. In addition, a connecting block 43 is rotatably connected to one end of the fixed shaft 2, and one side of the connecting block 43 is connected to the external hydraulic rod 44, wherein the external hydraulic rod 44 is fixedly installed on both sides of the conveyor 11.

[0052] Therefore, when the outer hydraulic rod 44 is extended, it pushes the connecting block 43 to move, and due to the cooperation between the gear 41 and the rack 42, the fixed shaft 2 and the drum 1 can be rotated while moving horizontally, so the position of the glassware can be changed. During this process, the limit block 31 continues to move in the limit slot 32 because the limit block 31 and the fixed shaft 2 are rotationally connected.

[0053] like Figure 1 As shown, when the driving mechanism 4 pushes the roller 1 to an angle of 270°, the glassware is located below the roller 1 and just enters the coating pool to start soaking in the coating. If the roller continues to rotate, the glassware is taken out and the next step can be performed. The inner hydraulic rod 5 and the outer hydraulic rod 44 are retracted, and the device returns to the initial state.

[0054] In this embodiment, only one working station is provided in the drum 1, that is, only one glass vessel can be clamped at a time. In actual use, the length of the drum 1 can be extended and multiple working stations can be provided to achieve the purpose of improving efficiency.

[0055] The implementation process and principle of an adjustable coating device for glassware processing in the embodiment of the present application are as follows:

[0056] (I): First, the inner hydraulic rod 5 extends to push the bow 6 forward, and the bow 6 drives the slider 74 to move through the oblique connecting rod 77;

[0057] When the clamping claw 72 does not contact the glassware, the slider 74 is blocked by the spring 76, and the slider 74 will push the entire clamping plate 71 to move forward together through the spring 76. When the guide plate 73 moves, it will also drive the two clamping plates 71 to move closer to the middle. At this time, the supporting ring 10 used for support can provide a limit and guiding effect for the movement of the guide plate 73.

[0058] When the clamping jaws 72 contact the glassware, if the glassware is of the same thickness at the top and bottom, the upper and lower sets of clamping jaws 72 will clamp the glassware at the same time;

[0059] If the glassware is uneven in thickness, Figure 1For a glass vessel that is thick in the middle and lower part and thin at the top, the lower clamping claw 72 will first contact the glass vessel. At this time, the bow 6 will continue to move, and the clamping plate 71 and the clamping claw 72 at the bottom will be blocked by the glass vessel and will no longer move. At this time, the slider 74 will move along the guide rod 75, compressing the spring 76, while the upper clamping plate 71 and the clamping claw 72 will continue to move until the glass vessel is clamped.

[0060] Therefore, the device can flexibly clamp different types of glassware without providing a separate clamping claw 72 for each glassware. Moreover, since a plurality of threaded holes are provided on the guide plate 73, the limit block 8 can be placed in a threaded hole according to the size of the glassware. When the guide plate 73 moves, if the limit block 8 touches the limit frame 9 fixed on the outer wall of the drum 1, the guide plate 73 stops moving, and the clamping plate 71 and the clamping claw 72 are also unable to move, which can prevent the clamping plate 71 and the clamping claw 72 from moving too far, resulting in excessive pressure on the glassware and causing damage to the glassware.

[0061] (II): After the clamping work is completed, the outer hydraulic rod 44 is started to push the connecting block 43 to move. The cooperation between the gear 41 and the rack 42 will make the fixed shaft 2 and the drum 1 rotate while moving horizontally. After the rotation angle reaches 270°, the glassware is located under the drum 1 and just enters the coating pool and begins to be immersed in the coating. If it continues to rotate, the glassware will be taken out and the next step can be carried out. The inner hydraulic rod 5 and the outer hydraulic rod 44 are retracted, and the device returns to the initial state.

[0062] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
