Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to an adhesive feeding device. Background Art

[0002] Adhesive is a sticky substance that can connect two separate materials together by virtue of its stickiness. As one of the important auxiliary materials, adhesive is widely used in packaging operations.

[0003] In the Chinese utility model patent with the announcement number CN220010762U, an adhesive feeding device is disclosed. The device enables the connecting rod and the spring to be extended and retracted by the weight of the raw material on the material guide, and the traction rod is pulled by the material guide, so that the partition can perform horizontal reciprocating motion in the placement groove, so as to adjust the discharge speed according to the weight of the raw material on the material guide, thereby avoiding the blockage in the discharge process caused by the excessive discharge speed. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, the adhesive will stick to the material guide after contacting it, and it is difficult for the device to automatically clean the surface after guiding the material, so that more and more adhesive will be attached to the material guide, and its overall weight will continue to increase, which will cause the opening of the partition and the feed pipe to continue to decrease, and then easily cause blockage. In order to prevent the above situation from occurring, it is necessary to manually push the push rod to frequently clean the material guide, which is not only troublesome, but also affects the continuity of the use of the device. For this reason, we provide an adhesive feeding device. Utility Model Content

[0005] In order to solve the problem in the above background technology that it is difficult to automatically scrape the stuck adhesive, which easily affects the normal feeding of the device, the utility model provides an adhesive feeding device.

[0006] The utility model adopts the following technical solution to achieve: an adhesive feeding device, comprising:

[0007] A feeding box, the top of which is fixedly connected to a feeding channel, and a feeding frame is arranged inside the feeding box;

[0008] The scraping and conveying assembly comprises sliding rods symmetrically fixedly connected to the feeding frame, two groups of sliding rods are externally slidably connected to the same slide plate, a scraper is arranged below the slide plate, a vertical rod is symmetrically fixedly connected to the top of the scraper and slidably connected to the slide plate, a spring is sleeved on the outside of the vertical rod, and a connecting rod is hinged between the slide plate and one side of the top of the inner cavity of the feeding box;

[0009] A bidirectional screw rod is rotatably connected to the bottom of the inner cavity of the feeding box, and movable plates are threadedly connected to the outside of both sides of the bidirectional screw rod. A connecting rod is symmetrically hinged between the movable plate and the feeding frame. A motor is fixedly connected to the bottom of the inner cavity of the feeding box, and the rotor end of the motor is coaxially fixedly connected to the bidirectional screw rod.

[0010] As a further improvement of the above scheme, a push plate is arranged above the feeding channel, connecting frames are fixedly connected on both sides of the feeding frame, a cross bar is symmetrically fixedly connected above the push plate, movable plates are slidably connected to the outside of both sides of the cross bar, connecting rod three is symmetrically hinged between the movable plate and the connecting frame on the opposite side, and connecting rod four is hinged between the movable plate and the push plate.

[0011] As a further improvement of the above solution, a discharge port is provided at a lower portion of one side of the feeding box.

[0012] As a further improvement of the above solution, a guide block is symmetrically fixedly connected to one side of the feeding frame, and a guide rod is symmetrically fixedly connected to the inside of the feeding box and is slidably connected to the guide block.

[0013] As a further improvement of the above solution, the length of the scraper is consistent with the width of the inner cavity of the feeding frame.

[0014] As a further improvement of the above solution, both sides of the bidirectional screw are fixedly connected to limit rods and are slidably connected to the movable plate.

[0015] As a further improvement of the above solution, the area of ​​the push plate is consistent with the cross-sectional area of ​​the feeding channel.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model drives the two-way lead screw to rotate forward and reversely through a motor, so that the two sets of movable plates can be driven to move toward or away from each other, and the movable plate and the hinged effect between the feeding frame and the second connecting rod can be used to drive the feeding frame to move vertically. At the same time, when the feeding frame moves vertically downward, the sliding cooperation between the slide plate and the slide rod, the hinged cooperation between the slide plate and the top of the inner cavity of the feeding box and the first connecting rod can be used to drive the slide plate to slide on the slide rod at the same time, so that the scraper can be driven to move together to push and scrape the adhesive on the feeding frame, thereby achieving the purpose of automatically scraping the adhesive, and effectively avoiding the problem that it is difficult to automatically scrape the sticky adhesive, which easily affects the normal feeding of the device.

[0018] 2. The utility model can drive the connecting frame to move downward together with the feeding frame when the feeding frame moves downward vertically. By utilizing the hinged action between the connecting frame and the movable plate on the opposite side and the connecting rod three, and the sliding cooperation between the movable plate and the cross bar, the two groups of movable plates can be driven to move toward each other. Moreover, under the hinged action cooperation between the movable plate and the push plate and the connecting rod four, the push plate can be pushed to move vertically downward into the interior of the feeding channel, thereby facilitating the removal of the adhesive attached to the inner wall during feeding, thereby further improving the practicality of the device.

[0025] Embodiment 1:

[0026] Please combine Figure 1-3 , an adhesive feeding device of this embodiment includes:

[0027] A feeding box 1, the top of which is fixedly connected to a feeding channel 2, a feeding frame 3 is arranged inside the feeding box 1, the top and one side of the feeding box 1 are both designed to be open, and one side thereof is in close contact with the inner wall of the feeding box 1, a discharge port is provided at the lower part of one side of the feeding box 1, so as to facilitate the discharge of the adhesive from the feeding box 1, a guide block 4 is symmetrically fixedly connected to one side of the feeding frame 3, a guide rod is symmetrically fixedly connected to the inside of the feeding box 1 and is slidably connected to the guide block 4, and can play a certain guiding role in the vertical movement of the feeding frame 3;

[0028] The scraping and conveying assembly includes a sliding bar 101 symmetrically fixedly connected to the feeding frame 3, two sets of sliding bars 101 are externally slidably connected to the same slide plate 102, a scraper 103 is arranged below the slide plate 102, a vertical rod 104 is symmetrically fixedly connected to the top of the scraper 103 and is slidably connected to the slide plate 102, a spring 105 is sleeved on the outside of the vertical rod 104, a connecting rod 106 is hinged between the slide plate 102 and one side of the top of the inner cavity of the feeding box 1, and the length of the scraper 103 is consistent with the width of the inner cavity of the feeding frame 3, which can ensure the thoroughness of scraping off the adhesive and prevent residue;

[0029] A bidirectional screw rod 107 is rotatably connected to the bottom of the inner cavity of the feeding box 1. The outer sides of the bidirectional screw rod 107 are threadedly connected to a movable plate 108. A connecting rod 109 is symmetrically hinged between the movable plate 108 and the feeding frame 3. A motor is fixedly connected to the bottom of the inner cavity of the feeding box 1 and the rotor end of the motor is coaxially fixedly connected to the bidirectional screw rod 107. Both sides of the bidirectional screw rod 107 are fixedly connected to the limiting rod 5 and are slidably connected to the movable plate 108, which can play a certain guiding role in the horizontal movement of the movable plate 108.

[0030] The implementation principle of an adhesive feeding device in the embodiment of the present application is as follows: first, the adhesive is fed into the feeding box 1 through the feeding channel 2, and the adhesive entering the feeding box 1 will fall onto the feeding frame 3, and then the motor is started, and the motor drives the bidirectional screw rod 107 to rotate, so that it can drive the two sets of movable plates 108 threadedly connected thereto to move back to back, and utilize the hinged effect between the movable plate 108 and the feeding frame 3 and the connecting rod 109 to drive the feeding frame 3 to move vertically downward. At the same time, in the process of the vertical downward movement of the feeding frame 3, the sliding plate 102 and the sliding rod 101 are used to slide together, and the sliding plate 102 and the top of the inner cavity of the feeding box 1 The hinged cooperation between the part and the connecting rod 106 can simultaneously drive the slide plate 102 to slide on the slide rod 101, thereby driving the scraper 103 to move together to push and scrape the adhesive on the feeding frame 3, thereby achieving the purpose of automatically scraping the adhesive. The scraped adhesive will be discharged through the discharge port, and finally the motor will drive the bidirectional screw rod 107 to reverse to reset the feeding frame 3. At this time, the scraper 103 will also be reset together, and the sliding cooperation between the vertical rod 104 and the slide plate 102 and the elastic effect of the spring 105 are utilized to ensure that the scraper 103 will always keep close contact with the surface of the feeding frame 3.

[0031] Embodiment 2:

[0032] On the basis of Example 1, the present embodiment is further improved in that: a push plate 201 is arranged above the feeding channel 2, connecting frames 202 are fixedly connected on both sides of the feeding frame 3, a cross bar 203 is symmetrically fixedly connected above the push plate 201, and movable plates 204 are slidably connected to the outside of both sides of the cross bar 203, a connecting rod three 205 is symmetrically hinged between the movable plate 204 and the connecting frame 202 on the opposite side, and a connecting rod four 206 is hinged between the movable plate 204 and the push plate 201, the area of ​​the push plate 201 is consistent with the cross-sectional area of ​​the feeding channel 2, so as to ensure the thoroughness of clearing the feeding channel 2, and when the feeding frame 3 moves downward vertically, it can also drive the connecting frame 202 to move downward together, and utilize the connecting frame 202 and the movable plate 204 on the opposite side and the connecting rod three The hinged action between 205 and the sliding cooperation between the movable plate 204 and the cross bar 203 can drive the two groups of movable plates 204 to move toward each other, and under the hinged action between the movable plate 204 and the push plate 201 and the connecting rod four 206, the push plate 201 can be pushed to move vertically downward into the interior of the feeding channel 2, so as to facilitate the removal of the adhesive attached to its inner wall during feeding. When the feeding frame 3 moves vertically upward, it can drive the push plate 201 to reset. Since the feeding port of the feeding channel 2 is located at a position deviating from the center of the feeding frame 3, when the push plate 201 enters the feeding channel 2 for scraping, the scraper 103 just moves to the feeding channel 2, thereby ensuring that the adhesive scraped out of the feeding channel 2 is pushed out of the feeding frame 3 together.

[0033] 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.
