Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, and more specifically, to a label paper feeding device for a casting machine. Background Art

[0002] A label is a tool used to mark the target, classification and content of a product, making it easier for oneself and others to find and locate their targets. Most of the labels referred to in the printing industry are printed materials used to identify the relevant instructions of their own products, and most of them have adhesive on the back, but some are printed without adhesive, which can also be called labels, and labels with adhesive are commonly known as "self-adhesive labels".

[0003] When operators are producing and processing labels, they often use a cast-film machine. When loading the existing cast-film machine, the operator needs to manually put the roller wrapped with label paper on the fixed shaft of the cast-film machine, and then drive the label paper to move through another set of transmission mechanisms, thereby feeding the cast-film machine. Although this method can achieve the purpose of feeding operation, due to the fixed size of the fixed shaft on the cast-film machine, the cast-film machine can only fix rollers of the same size, thereby reducing the applicability of the product. If rollers of different sizes need to be fixed, the operator needs to manually replace the fixed shaft to match the sizes of different rollers, which increases the operator's workload and reduces production efficiency, bringing inconvenience to the operator's operation, so it needs to be improved.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, the utility model provides a label paper feeding device for a casting machine, comprising:

[0031] The base 1 has an anti-sticking plate 2 fixedly mounted on the right side of the top of the base 1, a first handle 3 fixedly mounted on the top of the base 1, a fixing plate 4 fixedly mounted on the left side of the back of the base 1, a square rod 5 fixedly sleeved inside the fixing plate 4, a circular plate 6 fixedly mounted on the front end of the square rod 5, and a limiting groove 7 is provided on the outer surface of the circular plate 6;

[0032] A clamping mechanism is provided on the outer surface of the square rod 5;

[0033] Among them, the clamping mechanism includes a round block 8, the interior of the round block 8 is movably connected to the outer surface of the square rod 5, the back of the round block 8 is movably connected to the outer surface of the fixed plate 4, the front of the round block 8 is fixedly installed with a first spring 9, the interior of the first spring 9 is movably connected to the outer surface of the square rod 5, the front end of the first spring 9 is fixedly connected to the back of the circular plate 6, the outer surface of the round block 8 is fixedly installed with a first hinge block 10, the interior of the first hinge block 10 is hinged with a motion rod 11, and the other end of the motion rod 11 is hinged to a second hinge block 1 2. A moving block 13 is fixedly installed on the front of the second hinge block 12. The outer surface of the moving block 13 is movably connected to the inside of the limiting groove 7. A second spring 14 is fixedly installed on the outer surface of the moving block 13. The other end of the second spring 14 is fixedly connected to the inside of the limiting groove 7. A moving plate 15 is fixedly installed on the front of the moving block 13. A short rod 16 is fixedly sleeved on the inside of the bottom end of the moving plate 15. A roller 17 is movably sleeved on the outer surface of the short rod 16. The outer surface of the roller 17 is movably connected to the inside of the bottom end of the moving plate 15.

[0034] When the round block 8 moves forward along the square rod 5, the first spring 9 will be compressed. At the same time, the round block 8 will drive the three first hinge blocks 10 to move forward. At this time, the three first hinge blocks 10 will drive the three second hinge blocks 12 to move through the three motion rods 11. Due to the limiting effect of the three limiting grooves 7, the three second hinge blocks 12 will drive the three motion blocks 13 to move outward. At this time, the three second springs 14 will be compressed. At this time, the three motion plates 15 will move outward as a whole under the drive of the three motion blocks 13. The elastic force of a spring 9 will have a good reset effect on the movement of the round block 8. When the round block 8 moves backward under the drive of the first spring 9, the three moving blocks 13 will drive the three moving plates 15 to move inward as a whole. At this time, the three rollers 17 will clamp and fix the label roller during the inward movement. Due to the elastic force of the three second springs 14, the three rollers 17 will always fit with the label roller. Since the three rollers 17 are movably connected to the three short rods 16 respectively, the three rollers 17 can rotate along the outer surfaces of the three short rods 16.

[0035] A vertical plate 18 is fixedly mounted on the outer surface of the round block 8 , and a second handle 19 is fixedly mounted on the top of the vertical plate 18 .

[0036] Due to the design of the second handle 19 , the operator can drive the round block 8 to move through the second handle 19 and the vertical plate 18 .

[0037] A connecting rod 20 is fixedly sleeved inside the fixing plate 4 , and a front end of the connecting rod 20 is fixedly connected to the back side of the circular plate 6 .

[0038] Due to the design of the three connecting rods 20 , the circular plate 6 as a whole can be well supported.

[0039] A guide rod 21 is fixedly sleeved on the interior of the base 1 , and a guide block 22 is movably sleeved on the outer surface of the guide rod 21 .

[0040] Due to the design of the plurality of guide rods 21, a good guiding effect will be provided to the label paper. Due to the design of the plurality of guide blocks 22, the label paper will not be displaced during loading.

[0041] Among them, a fixed box 23 is fixedly installed on the outer surface of the base 1, a through slot 24 is opened at the top of the fixed box 23, a motor 25 is fixedly installed on the left side inside the fixed box 23, and the other end of the output shaft of the motor 25 is fixedly sleeved with a rotating shaft 26, and the other end of the rotating shaft 26 is fixedly sleeved with a rotating wheel 27.

[0042] When the motor 25 is running, the rotating shaft 26 will drive the rotating wheel 27 to rotate.

[0043] Among them, a first round rod 28 is fixedly sleeved inside the fixed box 23, and a second rubber wheel 29 is movably sleeved on the outer surface of the first round rod 28. A rotating gear 30 is fixedly installed at one end behind the second rubber wheel 29, and the rotating gear 30 is connected to the rotating wheel 27 through a transmission belt 31.

[0044] Since the outer surface of the first round rod 28 is movably connected to the inner part of the second rubber wheel 29, the second rubber wheel 29 can rotate on the outer surface of the first round rod 28. When the rotating wheel 27 rotates, the rotating wheel 27 drives the rotating gear 30 and the second rubber wheel 29 to rotate through the transmission belt 31.

[0045] The outer surface of the second rubber wheel 29 is movably connected to the first rubber wheel 33 , and the interior of the first rubber wheel 33 is movably sleeved with the second round rod 32 . The front and rear ends of the second round rod 32 are fixedly sleeved with the interior of the fixed box 23 .

[0046] Since the outer surface of the second round rod 32 is movably connected to the inner part of the first rubber wheel 33, the first rubber wheel 33 can rotate on the outer surface of the second round rod 32. When the second rubber wheel 29 rotates, the second rubber wheel 29 will cooperate with the first rubber wheel 33 to drive the label paper to move.

[0047] A fixed shaft 34 is fixedly mounted on the front of the circular plate 6 , a short slot 35 is formed on the outer surface of the fixed shaft 34 , and a shift lever 36 is hinged to the rear of the short slot 35 .

[0048] Since the rear ends of the three shift rods 36 are respectively hinged to the inside of the three short slots 35 , the three shift rods 36 can rotate around the hinged positions with the inside of the three short slots 35 as axes.

[0049] Among them, the front end of the fixed shaft 34 is fixedly installed with a fixed block 37, the interior of the fixed block 37 is movably sleeved with a rotating block 38, the back of the rotating block 38 is fixedly installed with a screw 39, the other end of the screw 39 is movably connected to the interior of the fixed shaft 34, the outer surface of the screw 39 is threadedly sleeved with a movable block 40, the outer surfaces of the movable block 40 are respectively movably sleeved with the interior of the fixed shaft 34 and the short slot 35, the inner part of the outer surface of the movable block 40 is hinged with a movable rod 41, and the rear end of the movable rod 41 is hinged to the inner part of the front end of the gear lever 36.

[0050] Due to the internal design of the fixed block 37, the rotating block 38 can only rotate inside the fixed block 37. When the rotating block 38 rotates, the screw 39 will rotate driven by the rotating block 38. Since the outer surface of the screw 39 is engaged with the internal thread of the movable block 40, when the screw 39 rotates, it will drive the movable block 40 to move backward. At this time, the movable block 40 will respectively drive the three movable rods 41 to move. At this time, the rear end of the three movable rods 41 will squeeze and push the front end of the three gear rods 36 during the movement. At this time, the three gear rods 36 will respectively rotate with the hinged joints with the inside of the three short slots 35 as the axis. When the three gear rods 36 rotate ninety degrees, the three gear rods 36 will block the movement of the label roller.

[0051] The front end of the fixed block 37 is movably connected to a circular block 42 , the back of the circular block 42 is fixedly connected to the front of the rotating block 38 , and the front of the circular block 42 is fixedly mounted with a twisting block 43 .

[0052] When the circular block 42 rotates, the circular block 42 drives the rotating block 38 to rotate. Due to the design of the twisting block 43 , the operator can conveniently drive the circular block 42 to rotate by twisting the block 43 .

[0053] The working principle and use process of this utility model:

[0054] First, the operator pulls the second handle 19. At this time, the second handle 19 will drive the round block 8 to move through the vertical plate 18. Due to the design of the square rod 5, the movement of the round block 8 will be limited so that it can only move forward and backward. At this time, the round block 8 will move forward along the outer surface of the square rod 5 under the drive of the vertical plate 18. During this process, the first spring 9 will be in a compressed state. At the same time, the round block 8 will simultaneously drive the three first hinge blocks 10 to move forward. Then, the three first hinge blocks 10 will respectively drive the three motion rods 11 to move. At this time, the other ends of the three motion rods 11 will respectively drive the three second hinge blocks 12 to move. Then, the three second hinge blocks 12 will respectively drive the three motion blocks 13 to move. Due to the design of the three limiting grooves 7, the movement of the three motion blocks 13 will be limited. At this time, the three motion blocks 13 will move outward along the inside of the three limiting grooves 7 under the drive of the three second hinge blocks 12. During this process, the three second springs 14 will be in a compressed state. At the same time, the three motion blocks 13 will respectively drive the three motion plates 15 to move outward The three moving plates 15 will move outwards through the three short rods 16. The operator will then sleeve the roller with the label wrapped around the outer surface of the fixed shaft 34. The operator will then release the second handle 19. Due to the elastic force of the first spring 9, the round block 8 will move backwards driven by the first spring 9. Due to the elastic force of the three second springs 14, the three moving blocks 13 will move inwards driven by the three second springs 14. The three moving plates 15 will move inwards as a whole under the guidance of the three moving blocks 13. The three rollers 17 will move inwards under the action of the springs 14. When the three rollers 17 come into contact with the label on the roller during the inward movement, the three rollers 17 will clamp the roller as a whole. Due to the elastic force of the three second springs 14, the three rollers 17 will always clamp the label roller as a whole, thereby realizing the function of fixing label rollers of different sizes. Since the outer surfaces of the three short rods 16 are movably connected to the outer surfaces of the three rollers 17 respectively, when the label roller rotates, the three rollers 17 will rotate driven by the label roller.

[0055] When the outer surface of the three gear rods 36 contacts the outer surface of the label roller during rotation, the three gear rods 36 will block the label roller, thereby preventing the label roller from being displaced during rotation.
