Description

Technical Field

[0001] The utility model relates to the field of glass production, in particular to an injection glass trimming tool. Background Art

[0002] At present, in the production process of injection molded glass, the center seam of the injection mold will cause flash to form on the edge of the glass. In order to improve product quality, it is necessary to remove the flash and make the edge of the glass smooth again, which is called trimming. One of the commonly used methods of trimming is grinding. Smaller flash can be removed by grinding, and grinding can also make the edge of the glass smooth again. For manual trimming, firstly, the existing handheld grinder has no dust suction structure, and a lot of dust and debris will be generated during grinding, polluting the working environment. Secondly, manual grinding is inefficient and the accuracy cannot be guaranteed. Based on this, the applicant proposes an injection molded glass trimming tool, which has the advantages of low environmental pollution and high grinding accuracy. Utility Model Content

[0003] In order to solve the technical problems of low grinding and trimming efficiency and great pollution, the utility model provides an injection molded glass trimming tool.

[0004] The utility model is implemented by the following technical scheme: an injection glass trimming tool, comprising a base, on which are arranged:

[0005] A grid plate, the grid plate is fixedly connected to the base, and the grid plate is used to support the glass;

[0006] A clamping plate, the clamping plate is used to fix the glass, and the clamping plate includes a fixed clamping plate and a movable clamping plate;

[0007] An installation box, the installation box is arranged above the base, and the installation box can move along the base;

[0008] Grinding rollers, two of which are provided, and the two grinding rollers are movably arranged below the installation box, and the distance between the two grinding rollers is adjustable.

[0009] According to the above technical solution, the glass to be edged is first placed on the grid plate, and the movable clamp is moved and fixed with the fixed clamp. Since the size of the glass is known, the two grinding rollers are moved so that the two grinding rollers can just fit the two sides of the glass. When the grinding roller rotates, the edge of the glass is polished and trimmed. At the same time, the entire installation box can move along the direction of the base, that is, the grinding roller can rotate and move along the edge of the glass, so that the glass in a larger range can be polished.

[0010] As a further improvement of the above solution, a downward groove is provided in the middle of the base, the grid plate and the clamping plate are arranged in the groove, and a water inlet and a water outlet are provided on the side of the base.

[0011] Through the above technical solution, a groove is opened in the middle of the base, and a water inlet and outlet are provided, that is, water can be introduced. In actual use, dust and debris will be generated during grinding. In order to prevent dust and debris from floating in the air, water can be used to collect the dust and debris, providing a good working environment for production.

[0012] As a further improvement of the above solution, one side of the movable splint is rotatably connected to a threaded push rod, the other end of the threaded push rod extends out of the base, and the threaded push rod and the base are threadedly connected.

[0013] Through the above technical solution, by rotating the threaded push rod, the movable clamping plate can be pushed to move closer to or away from the fixed clamping plate, thereby fixing or loosening the glass.

[0014] In this embodiment, the movable clamping plate and the inner side of the fixed frame plate (the side close to the glass) are arranged in a "7" shape and are provided with an inclined surface, which is convenient for fixing glass of different thicknesses and can prevent the glass from jumping during trimming.

[0015] As a further improvement of the above solution, installation grooves are provided on both sides of the base, a driving shaft is rotatably installed in the installation groove, one end of the driving shaft is connected to a first motor, and the lower end of the installation box is sleeved on the outside of the driving shaft.

[0016] Through the above technical solution, when the first motor drives the driving shaft to rotate, the mounting box can be driven to move along the axial direction of the driving shaft, so that the position of the grinding roller can be adjusted to grind and trim the side edge of the glass.

[0017] As a further improvement of the above solution, an inner connecting frame is provided below the installation box, a second motor is installed on the inner connecting frame, a grinding roller is connected to the second motor, and baffles are provided on the inner connecting frame and on both sides of the grinding roller.

[0018] Through the above technical solution, the grinding roller is driven to rotate by the second motor to grind and trim the side of the glass. At the same time, the baffle can prevent the dust generated during grinding from splashing. After being blocked by the baffle, most of the dust will automatically fall into the groove on the base, that is, fall into the water.

[0019] As a further improvement of the above solution, the installation box is provided with an adjustment mechanism, the adjustment mechanism is used to adjust the distance between the two inner connecting frames, and the adjustment mechanism includes:

[0020] A slide plate, wherein the mounting box is provided with a limiting hole, the slide plate is clamped in the limiting hole and can move along the limiting hole, and a rack is fixedly connected to the side of the slide plate;

[0021] A gear is installed inside the box body and is rotatably connected with the gear, the gear is meshed with the rack, and two of the slide plate and the rack are respectively arranged on both sides of the gear.

[0022] A control shaft is fixedly connected to the gear, the control shaft is rotationally connected to the mounting box, and the upper end of the control shaft extends out of the mounting box.

[0023] As a further improvement of the above solution, the slide plate and the inner connecting frame are fixedly connected.

[0024] Through the above technical solution, when the gear is driven to rotate by the control shaft, the gear drives the slide plate to move in the limiting hole through the meshing tooth plates on both sides, thereby driving the inner connecting frame to move, so the grinding roller installed on the inner connecting frame is driven to move together, so the two slide plates are respectively located on both sides of the gear and are meshed with the gear. Therefore, when the gear rotates, the two inner connecting frames (grinding rollers) can be driven by the slide plate to move closer to or away from each other.

[0025] As a further improvement of the above solution, a fixing mechanism is further provided between the control shaft and the mounting box, and the fixing mechanism comprises:

[0026] A sleeve, the sleeve is movably sleeved on the outer side of the control shaft, and the sleeve is movably mounted on the mounting box, and an inner limit tooth is provided on the inner wall of the sleeve;

[0027] A card plate is rotatably connected to the side of the control shaft, and a spring is arranged between the card plate and the control shaft.

[0028] Through the above technical solution, a hole is opened on the top of the installation box. First, the control shaft extends out of the installation box through the hole. At the same time, a sleeve is arranged at the hole. The sleeve is sleeved on the outside of the control shaft. At the same time, the sleeve can move up and down along the control shaft within a certain range. The upper half of the inner wall of the sleeve is fixedly connected with a circle of internal limit teeth, and the clamping plate on the control shaft pops out under the action of the spring and is stuck on the internal limit teeth, so that the control shaft can only rotate in one direction, and it will be stuck when rotating in the opposite direction.

[0029] However, lift the sleeve upwards so that the inner limit tooth is away from the clamping plate, and the control shaft can rotate forward or backward at this time.

[0042] 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.

[0043] Please combine Figure 1 and Figure 2 The present embodiment is an injection glass trimming tool, comprising a base 1. First, the middle of the base 1 is sunken downward to form a groove in the middle. At the same time, a water inlet 11 and a water outlet 12 are provided on the side of the base 1 to facilitate the inflow of water. A plurality of grid plates 13 are fixedly connected in the groove. The grid plates 13 are disconnected in the middle to not affect the flow of water in the groove. At the same time, the grid plates 13 are used to support glass.

[0044] In order to fix the glass on the grid plate 13, a clamping plate 2 is also provided. The clamping plate 2 includes a fixed clamping plate 21 and a movable clamping plate 22. First, the fixed clamping plate 21 is fixedly connected to the base 1, and a threaded push rod 23 is rotatably connected to one side of the movable clamping plate 22. The threaded push rod 23 is threadedly connected to the base 1, and one end of the threaded push rod 23 extends out of the base 1. Therefore, when the threaded push rod 23 is rotated, the movable clamping plate 22 can be pushed to move closer to or away from the fixed clamping plate 21.

[0045] In order to facilitate the fixing of the glass, the movable clamping plate 22 and the inner side of the fixed frame plate (the side close to the glass) are set in a "7" shape and are provided with an inclined surface to facilitate the fixing of glass of different thicknesses and prevent the glass from bouncing and jumping during trimming.

[0046] Please combine Figure 3 - Figure 8 In order to correct and polish the edge of the glass, a grinding roller 7 is provided. Two grinding rollers 7 are provided, which are respectively provided on both sides of the glass to grind and trim both sides of the glass at the same time. A second motor (not marked in the figure) is connected above the grinding roller 7, that is, the second motor can drive the grinding roller 7 to rotate. In addition, an inner connecting frame 6 is provided, and the second motor is installed on the inner connecting frame 6.

[0047] In addition, baffles 8 are installed on the inner connecting frame 6 and on both sides of the grinding roller 7. When the grinding roller 7 rotates to grind and trim the glass, dust and debris will be generated. The baffles 8 can resist the dust and debris to a certain extent and prevent the dust from floating in the air. Under the obstruction of the baffles 8, part of the dust will fall on the base 1 below, that is, fall into the water, providing a good working environment for production.

[0048] Because the sizes of the glasses are different, in order to make the grinding roller 7 fit the edge of the glass, the positions of the two grinding rollers 7 need to be adjusted.

[0049] In summary, a mounting box 3 is arranged above the base 1, and an adjustment mechanism 4 is arranged inside the mounting box 3. The adjustment mechanism 4 is used to adjust the positions of the two grinding rollers 7. Specifically, the adjustment mechanism 4 includes a slide plate 42. First, a long strip-shaped limiting hole 41 is opened at the inner bottom of the mounting box 3. The slide plate 42 is clamped in the limiting hole 41 and can slide along the direction of the limiting hole 41. A rack 43 is also fixedly arranged on the side of the slide plate 42. A control shaft 45 is rotatably installed in the middle of the mounting box 3. A gear 44 is installed on the control shaft 45. The control shaft 45 is rotatably connected to the mounting box 3. In addition, the gear 44 is meshed with the rack 43 on the side of the slide plate 42.

[0050] There are two slide plates 42 and two racks 43, and the two slide plates 42 are respectively arranged on both sides of the gear 44, and the two racks 43 are meshed with the gear 44. Therefore, when the control shaft 45 and the gear 44 rotate, the racks 43 (slide plates 42) on both sides are driven to move in opposite directions.

[0051] The above-mentioned limiting hole 41 is a through hole, and the bottom of the slide plate 42 extends out of the limiting hole 41 and is fixedly connected to the inner connecting frame 6. Therefore, when the slide plate 42 moves, the inner connecting frame 6 will also be driven to move, so the second motor and the grinding roller 7 will also move together. In this way, the distance between the two grinding rollers 7 is adjusted to fit the side of the glass, and both sides of the glass of different sizes can be ground at the same time.

[0052] Since there is glass blocking between the two grinding rollers 7, the grinding rollers 7 will not move toward the middle. However, in order to prevent the grinding rollers 7 from moving outward (away from the glass), it is necessary to fix the position of the grinding rollers 7 after adjustment to prevent them from moving away from the glass, causing the grinding rollers 7 to fail to work.

[0053] In order to avoid the above situation, a through hole is firstly provided above the installation box 3, and the upper end of the control shaft 45 extends out of the installation box 3 through the through hole. In addition, a fixing mechanism 5 is provided between the control shaft 45 and the installation box 3.

[0054] Specifically, the fixing mechanism 5 includes a sleeve 51. First, the sleeve 51 is sleeved on the outside of the control shaft 45. Secondly, the upper and lower ends of the sleeve 51 are provided with edges extending outward. At the same time, the sleeve 51 is arranged at the through hole above the mounting box 3, and the upper and lower edges of the sleeve 51 are respectively located on the outside and inside of the mounting box 3, that is, the sleeve 51 is clamped at the through hole of the mounting box 3. At the same time, the sleeve 51 is not fixed, so it can move up and down.

[0055] A circle of inner limit teeth 52 is provided on the inner wall of the sleeve 51. In addition, a corresponding clamping plate 53 is rotatably connected to the side of the control shaft 45, and a spring 54 is connected between the clamping plate 53 and the control shaft 45.

[0056] like Figure 8 As shown, when the control shaft 45 rotates clockwise, the clamping plate 53 rotates and compresses the spring 54 at the same time. When the control shaft 45 rotates counterclockwise, the clamping plate 53 is blocked by the inner limit tooth 52 and cannot rotate counterclockwise.

[0057] In summary, when the control shaft 45 rotates clockwise, the slides 42 on both sides move, driving the two grinding rollers 7 to move closer to each other. Conversely, when the control shaft 45 rotates counterclockwise, the slides 42 on both sides move in the opposite direction, driving the two grinding rollers 7 to move away from each other. However, in actual use, there is glass between the two grinding rollers 7, and they will not get close to each other. Therefore, with the cooperation of the internal limit teeth 52 and the clamping plate 53, the control shaft 45 cannot rotate counterclockwise, and the two grinding rollers 7 cannot move away from each other. Therefore, a certain distance can be maintained between the two grinding rollers 7 without changing. Therefore, the grinding rollers 7 can always fit the side of the glass to ensure the grinding effect.

[0058] In addition, when the control shaft 45 needs to rotate counterclockwise, the sleeve 51 is pulled upward, and the sleeve 51 moves upward, so that the inner limit tooth 52 is disengaged from the clamping plate 53 upward, and the control shaft 45 can rotate counterclockwise at this time, so as to facilitate the adjustment of the distance between the two grinding rollers 7.

[0059] Please look back Figure 2 In order to grind the edge of the glass block and to support the installation box 3, installation grooves 14 are provided on both sides of the base 1. A driving shaft 15 is rotatably installed in the installation groove 14. The driving shaft 15 is a threaded shaft. One end of the driving shaft 15 is connected to a first motor (not marked in the figure), and the lower end of the installation box 3 is sleeved on the driving shaft 15. Therefore, when the first motor drives the driving shaft 15 to rotate, the installation box 3 can be moved along the axial direction of the driving shaft 15. Opposite to the driving shaft 15, a guide shaft (not marked in the figure) is fixedly provided in the installation groove 14 on the other side of the base 1, and the lower end of the installation box 3 is sleeved on the guide shaft. The guide shaft serves as a moving guide and limiter for the installation box 3.

[0060] The implementation process and principle of an injection glass trimming tool in the embodiment of the present application are as follows:

[0061] (I): Place the glass to be polished on the grid plate 13, and make one end of it against the fixed clamping plate 21, rotate the threaded push rod 23, control the movable clamping plate 22 to move, gradually approach the fixed clamping plate 21, and cooperate with the fixed clamping plate 21 to clamp the glass from both ends. At the same time, water flows into the base 1.

[0062] In actual use, if the glass size is known but there is no corresponding one, an indicator arrow (not marked in the figure) can be installed in the middle of the fixed clamp 21 and the movable clamp 22 to align the middle of the glass to facilitate the subsequent grinding roller 7 to contact the side of the glass from both sides.

[0063] (ii) Pull up the sleeve 51, the sleeve 51 moves upward, so that the inner limit tooth 52 moves upward and disengages from the clamping plate 53, and the control shaft 45 can rotate freely at this time. When the control shaft 45 and the gear 44 rotate, the slide plate 42 is driven to move, and the slide plate 42 drives the grinding roller 7 to move through the inner connecting frame 6, so that the distance between the two grinding rollers 7 can be adjusted conveniently, so that the two grinding rollers 7 are respectively fitted with the two sides of the glass. Therefore, the side edges of glass of different sizes can be beveled.

[0064] After the position of the grinding roller 7 is adjusted, the sleeve 51 is released, and the sleeve 51 naturally falls and resets. At this time, the clamping plate 53 clamps the inner limit tooth 52, and the control shaft 45 cannot rotate counterclockwise. The grinding roller 7 cannot move outward away from the glass, so that the grinding rollers 7 on both sides always keep in contact with the edge of the glass, thereby improving the grinding efficiency.

[0065] (III) The second motor drives the grinding roller 7 to rotate and grind the glass, which will generate dust and debris. The baffle 8 can block the dust and debris to a certain extent. Under the blocking of the baffle 8, part of the dust will fall into the water, preventing the dust from floating in the air. It provides a good working environment for production and is also convenient for subsequent cleaning.

[0066] At the same time, when the first motor drives the driving shaft 15 to rotate, it can drive the installation box 3 to move axially along the driving shaft 15 to trim and polish the entire glass side.

[0067] 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.
