Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of injection molding equipment, in particular to a residual glue cleaning mechanism for a glue dispensing machine. Background Art

[0002] In a dispensing machine, two or more different types of glue are mixed in the mixing tube. Over time, residual solidification will form on the inner wall of the mixing tube, affecting the discharge of glue. Therefore, the glue in the mixing tube needs to be discharged outward regularly to promote the discharge of the residual solidified part as waste glue to prevent clogging. At the same time, the needle of the dispensing machine is also prone to residual solidification after each dispensing stop. Therefore, the residual glue on the needle needs to be wiped clean.

[0003] The prior art uses a wiping structure to clean the residual glue contaminated by the needle, but its wiping structure is relatively fixed. After long-term use, the wiping structure is easily contaminated with residual glue on its surface. When cleaning the wiping structure, the running trajectory of the glue dispenser with the wiping structure is mostly set to move to the wiping position for wiping and then dispensing glue, so that cleaning will affect the normal operation of the glue dispenser and reduce the practicality of the device. Therefore, a glue residual cleaning mechanism for a glue dispenser is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the utility model to solve its technical problem is: the utility model relates to a glue dispensing machine residual glue cleaning mechanism, comprising a support plate, the outer side of the support plate is fixedly connected to the first motor, the output end of the first motor is fixedly connected to the positive and negative screw rods, the positive and negative screw rods and the support plate are rotatably connected, the outer side of the positive and negative screw rods are threadedly connected to a movable plate, the inner side of the movable plate is slidably connected to a fixed rod, the fixed rod and the support plate are fixedly connected, the outer side of the movable plate is fixedly connected to the second motor, the output end of the second motor is fixedly connected to a rotating plate, the inner side of the rotating plate is slidably connected to a movable block, the outer side of the movable block is fixedly connected to a wiping pad, the outer side of the movable plate is fixedly connected to a limited frame, and the rotating plate and the movable block are both connected to The limiting frame is used in conjunction with this step. By setting the positive and negative screw rods, movable plate, rotating plate and movable block, when the wiping pad can be used normally, the needle is moved between the wiping pads, and then the positive and negative screw rods are driven to rotate by the first motor, and the wiping pad is driven to move close to the needle by the positive and negative screw rods, and then the needle is pulled to clean the needle through the wiping pad. When the wiping pad needs to be replaced, the clean wiping pad is driven to the wiping position by the second motor, and then the contaminated wiping pad is taken out for cleaning and reinstalled through the notch of the limiting frame, so that there is always a clean wiping pad available at the wiping position, and the wiping pad can be taken out for cleaning, making it difficult for its cleaning to affect the operation of the dispensing machine, thereby improving the stability of the device.

[0006] Preferably, a cylinder is fixedly connected to the inner side of the support plate, and a scraper is fixedly connected to the output end of the cylinder. The scraper and the wiping pad are used in combination. In this step, by setting the cylinder and the scraper, after the wiping pad wipes the glue, the scraper can be driven downward by the cylinder, so that the scraper can clean the surface of the wiping pad, further reducing the residual glue adhering to the surface of the wiping pad, reducing its cleaning frequency, and improving the stability of the device operation.

[0007] Preferably, a baffle is fixedly and slidably connected to the inner side of the support plate, and a collection box is fixedly connected to the outer side of the support plate. The baffle and the collection box are used in combination. In this step, by setting the baffle and the collection box, when the scraper cleans the wiping pad, the scraped residual glue will fall between the collection box and the baffle instead of falling everywhere. After the collection box is full, the baffle can be pulled until it no longer blocks the residual glue, making it easy to move the residual glue out from the inside of the collection box, so that the user can clean the collection box, further improving the convenience of cleaning the device.

[0008] Preferably, the outer side of the support plate is slidably connected with an insertion rod, and a slot is provided on the surface of the baffle, and the insertion rod and the slot are slidably connected. In this step, by setting the insertion rod and the slot, when the baffle does not need to move, the insertion rod can be inserted into the inner side of the slot to fix the position of the baffle, so that the baffle will not move when blocking, causing residual glue to fall off, thereby improving the stability of the device.

[0009] Preferably, the scraper is slidably connected to a moving block on the inner side, and the scraper pad is fixedly connected to the outer side of the moving block. In this step, by setting the moving block and the scraper pad, when the scraper cleans the surface of the wiping pad, the scraper pad will contact the residual glue first, so that the scraper can be protected to a certain extent by the scraper pad, so that the scraper will not be contaminated with too much residual glue, thereby improving the convenience of cleaning the scraper by the device.

[0010] Preferably, a magnetic plate is fixedly connected to the outside of the rotating plate, and the magnetic plate is used in conjunction with the movable block. In this step, by setting the magnetic plate, after the movable block is placed inside the rotating plate, the movable block can be adsorbed by the magnetic plate, making the connection between the movable block and the rotating plate more stable, thereby making it less likely to fall off during rotation, thereby improving the stability of the device.

[0011] The utility model is beneficial in that:

[0012] 1. The utility model is provided with positive and negative threaded rods, a movable plate, a rotating plate and a movable block. When the wiping pad can be used normally, the needle head is moved between the wiping pads, and then the positive and negative threaded rods are driven to rotate by the first motor, and the wiping pad is driven to move close to the needle head by the positive and negative threaded rods, and then the needle head is pulled to clean the needle head through the wiping pad. When the wiping pad needs to be replaced, the clean wiping pad is driven to move to the wiping position by the second motor, and the contaminated wiping pad is taken out for cleaning and then reinstalled through the notch of the limit frame, so that there is always a clean wiping pad available at the wiping position, and the wiping pad can be taken out for cleaning, so that its cleaning is unlikely to affect the operation of the dispensing machine, thereby improving the stability of the device.

[0013] 2. The utility model is provided with a cylinder and a scraper. After the wiping pad wipes the glue, the cylinder can drive the scraper to press down, so that the scraper can clean the surface of the wiping pad, further reducing the residual glue adhering to the surface of the wiping pad, reducing its cleaning frequency, and improving the stability of the device operation.

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.

[0022] Specific examples are given below.

[0023] See also Figure 1-5As shown, a residual glue cleaning mechanism for a glue dispensing machine includes a support plate 1, the outer side of the support plate 1 is fixedly connected to a first motor 2, the output end of the first motor 2 is fixedly connected to a positive and negative screw rod 3, the positive and negative screw rod 3 and the support plate 1 are rotatably connected, the outer side of the positive and negative screw rod 3 is threadedly connected to a movable plate 4, the inner side of the movable plate 4 is slidably connected to a fixed rod 5, the fixed rod 5 and the support plate 1 are fixedly connected, the outer side of the movable plate 4 is fixedly connected to a second motor 6, the output end of the second motor 6 is fixedly connected to a rotating plate 7, the inner side of the rotating plate 7 is slidably connected to a movable block 8, the outer side of the movable block 8 is fixedly connected to a wiping pad 9, the outer side of the movable plate 4 is fixedly connected to a limiting frame 10, and the rotating plate 7 and the movable block 8 are both used in conjunction with the limiting frame 10, This step is achieved by setting the forward and reverse screw rods 3, the movable plate 4, the rotating plate 7 and the movable block 8. When the wiping pad 9 can be used normally, the needle is moved between the wiping pads 9, and then the forward and reverse screw rods 3 are driven to rotate by the first motor 2, and the wiping pad 9 is driven to move close to the needle by the forward and reverse screw rods 3, and then the needle is pulled to clean the needle through the wiping pad 9. When the wiping pad 9 needs to be replaced, the clean wiping pad 9 is driven to the wiping position by the second motor 6, and then the contaminated wiping pad 9 is taken out for cleaning and reinstalled through the notch of the limit frame 10, so that there is always a clean wiping pad 9 available at the wiping position, and the wiping pad 9 can be taken out for cleaning, so that its cleaning is unlikely to affect the operation of the dispensing machine, thereby improving the stability of the device.

[0024] Further, such as Figure 1 and Figure 5 As shown, the inner side of the support plate 1 is fixedly connected to a cylinder 11, and the output end of the cylinder 11 is fixedly connected to a scraper 12. The scraper 12 is used in conjunction with the wiping pad 9. In this step, by setting the cylinder 11 and the scraper 12, after the wiping pad 9 wipes the glue, the scraper 12 can be driven downward by the cylinder 11, so that the scraper 12 can clean the surface of the wiping pad 9, further reducing the residual glue adhering to the surface of the wiping pad 9, reducing its cleaning frequency, and improving the stability of the device operation.

[0025] Further, such as Figure 1 As shown, a baffle 13 is fixedly and slidably connected to the inner side of the support plate 1, and a collection box 14 is fixedly connected to the outer side of the support plate 1. The baffle 13 and the collection box 14 are used in conjunction with each other. In this step, by setting the baffle 13 and the collection box 14, when the scraper 12 cleans the wiping pad 9, the scraped residual glue will fall between the collection box 14 and the baffle 13 instead of falling everywhere. After the collection box 14 is full, the baffle 13 can be pulled until it no longer blocks the residual glue, so that the residual glue can be easily removed from the inside of the collection box 14, so that the user can clean the collection box 14, further improving the convenience of cleaning the device.

[0026] Further, such as Figure 1 As shown, the outer side of the support plate 1 is slidably connected with an insertion rod 15, and a slot 16 is provided on the surface of the baffle 13. The insertion rod 15 and the slot 16 are slidably connected. In this step, by setting the insertion rod 15 and the slot 16, when the baffle 13 does not need to move, the insertion rod 15 can be inserted into the inner side of the slot 16 to fix the position of the baffle 13, so that the baffle 13 will not move when blocking, causing the residual glue to fall off, thereby improving the stability of the device.

[0027] Further, such as Figure 5 As shown, the scraper 12 is slidably connected to a moving block 17 on the inner side, and the moving block 17 is fixedly connected to a scraper pad 18 on the outer side. In this step, by setting the moving block 17 and the scraper pad 18, when the scraper 12 cleans the surface of the wiping pad 9, the scraper pad 18 will come into contact with the residual glue first, so that the scraper 12 can be protected to a certain extent by the scraper pad 18, so that the scraper 12 will not be contaminated with too much residual glue, thereby improving the convenience of the device to clean the scraper 12.

[0028] Further, such as Figure 4 As shown, a magnetic plate 19 is fixedly connected to the outside of the rotating plate 7, and the magnetic plate 19 is used in conjunction with the movable block 8. In this step, by setting the magnetic plate 19, after the movable block 8 is placed inside the rotating plate 7, the movable block 8 can be adsorbed by the magnetic plate 19, so that the connection between the movable block 8 and the rotating plate 7 is more stable, so that it is not easy to fall off during rotation, thereby improving the stability of the device.

[0029] The working principle is to move the needle head between the wiping pads 9, and then drive the forward and reverse screw rods 3 to rotate through the first motor 2, and drive the wiping pad 9 to move close to the needle head through the forward and reverse screw rods 3, and then pull the needle head, and clean the needle head through the wiping pad 9, and then return the wiping pad 9 to its position, and then start the cylinder 11, and drive the scraper 12 and the scraping pad 18 to press down through the cylinder 11, so that the scraping pad 18 cleans the surface of the wiping pad 9, so that the scraped residual glue falls to the inside of the collection box 14. When the wiping pad 9 needs to be replaced, the rotating plate 7 is driven to rotate by the second motor 6, and the movable block 8 and the wiping pad 9 are driven to rotate through the rotating plate 7, so that the clean wiping pad 9 moves to the wiping position, and the contaminated wiping pad 9 moves to the notch of the limiting frame 10, and then the contaminated wiping pad 9 is taken out through the notch of the limiting frame 10 for cleaning and then reinstalled.
