Description

Technical Field

[0001] The invention relates to the technical field of round cap paper nail production, and in particular to automatic feeding equipment and method based on round cap paper nail processing. Background Art

[0002] Round cap paper nails (or round cap paper nails) are a type of nail commonly used to fix paper products and other lightweight materials. Round cap paper nails are divided into two parts: the nail body and the cap body. The nail body is made of metal material, and the cap body is usually made of paper material or plastic. When assembling the cap body and the nail body, glue needs to be applied on the cap body. The assembly process of the two requires the cap body and the nail body to be loaded separately.

[0003] The assembly of round cap paper nails is the lowest value-added part in the entire production line process, so many assembly manufacturers often have a relatively simple production environment. This will result in workers applying glue on the cap body during the high temperature in summer. While waiting for the nail body to be loaded, the glue will form a solidified part, resulting in poor assembly effect. However, due to the low processing profit, it is unrealistic to install large-scale temperature control equipment to change the room temperature environment on a large scale.

[0016] S1: Start the bottom cooling device to form a low temperature zone, a medium temperature zone and a normal temperature zone on the feeding cavity. A low boiling point liquid refrigerant is input into the circular frame through the infusion port. Under the action of time, the low boiling point liquid refrigerant absorbs the heat at the bottom of the feeding cavity to form a low temperature zone. The motor is started to drive the circular frame to rotate rapidly, so that the low boiling point liquid refrigerant is vaporized faster and forms centrifugal force. The low boiling point liquid refrigerant is dispersed, and the low boiling point liquid refrigerant vaporized into water rises to the cooling cavity to absorb the heat of the feeding cavity there, thereby forming a medium temperature zone.

Thus, the loading of the cap body is completed, and then wait for the loading of the external nail body;

[0018] S3: The cap body and the nail body are glued together, and the electric cylinder is started again to push the push rod up in the feeding cavity. The cap body will move to the medium temperature zone, where the temperature is still low, which can prevent the glue from solidifying during the movement. As the cap body continues to rise, it enters the normal temperature zone, and the nail body is delivered to the normal temperature zone of the feeding cavity through the feeding device of the nail body. The two are pushed by external force to stick together. At this time, the glue is in the normal temperature zone under the room temperature environment in summer, which will make the glue solidify quickly, and the cap body and the nail body are combined, and finally the nail is removed.

In addition, this method has a low production cost and does not require large-scale changes to the production environment, so that both cost and quality are taken into account.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Refer to the attached Figure 1-Figure 7 An automatic feeding device based on round cap paper nail processing includes a frame 1, a plurality of feeding cavities 2 are installed on the frame 1, and a cap body feeding mechanism 9 is installed to feed the feeding cavity 2 from bottom to top, a cooling mechanism 3 is installed outside the feeding cavity 2, and the cooling mechanism 3 includes a bottom cooling device 4 and a middle cooling device 5;

[0030] The bottom cooling device 4 is installed at the bottom of the feeding cavity 2 to form a low temperature zone 300 of the feeding cavity 2. The bottom cooling device 4 includes a shell 41 fixed on the feeding cavity 2, and also includes a circular frame 42 slidably installed in the shell 41 and rotatable, and a low-boiling point liquid refrigerant is input into the circular frame 42;

[0031] The low boiling point liquid refrigerant is input into the circular frame 42, and the low boiling point liquid refrigerant contacts the bottom of the feeding cavity 2 to absorb its heat, so that the temperature of the bottom of the feeding cavity 2 is reduced, forming a low temperature zone 300;

[0032] A middle cooling device 5, which is installed in the middle of the feeding cavity 2 to form a middle temperature zone 400 of the feeding cavity 2. The middle cooling device 5 includes an arc-shaped insulation shell 51 fixedly installed between the feeding cavity 2 and the outer shell 41. The cross-sectional area of ​​the arc-shaped insulation shell 51 increases from top to bottom. A cooling cavity 52 is formed between the arc-shaped insulation shell 51 and the outer wall of the feeding cavity 2. The cooling cavity 52 is connected to the circular frame 42. The circular frame 42 is provided with an anti-corrosion friction plate 7 fixedly connected to the feeding cavity 2;

[0033] The circular frame 42 rotates rapidly, causing the low-boiling-point liquid refrigerant to generate centrifugal force and disperse into the cooling chamber 52. The circular frame 42 rotates rapidly, causing the anti-corrosion friction plate 7 and the low-boiling-point liquid refrigerant to generate heat by friction, accelerating the vaporization process of the low-boiling-point liquid refrigerant. The water vapor can rise to a place that is not touched by the centrifugal force, so that the cooling chamber 52 can fully absorb the heat in the middle of the feeding chamber 2, thereby reducing the temperature in the middle of the feeding chamber 2 and forming a medium temperature zone 400°C.

[0034] The top of the feeding cavity 2 is located in a room temperature environment to form a normal temperature zone 500 , and the temperatures of the normal temperature zone 500 , the medium temperature zone 400 and the low temperature zone 300 decrease gradually.

[0035] The low-temperature zone 300 of the feeding cavity 2 is in direct contact with the low-boiling-point liquid refrigerant, and can absorb a large amount of heat, so that the temperature of the low-temperature zone 300 is the lowest. The medium-temperature zone 400 of the feeding cavity 2 is in contact with the dispersed and vapor-like low-boiling-point liquid refrigerant, and can absorb part of the heat, so that the temperature of the medium-temperature zone 400 is greater than the temperature of the low temperature. The normal temperature zone 500 of the feeding cavity 2 is not in contact with the low-boiling-point liquid refrigerant in any state, and it maintains the ambient temperature, so that the temperature is higher.

[0036] When the cap body feeding mechanism 9 feeds the glue-coated cap body from the bottom of the feeding cavity 2, it will wait for the loading of the nail body in the low-temperature zone 300 at the bottom of the feeding cavity 2. During this waiting process, the glue will not solidify due to the long waiting time. When the nail body is loaded, the two will move closer to each other. When the cap body moves, it will enter the medium temperature zone 400. At this time, the temperature is still low, which avoids the glue solidifying during the movement. When the two are in contact and sticky, they are located in the normal temperature zone 500. The normal temperature zone 500 has a relatively high temperature, which is convenient for the glue to solidify.

[0037] In the present embodiment, it should be noted that the low-boiling-point liquid refrigerant has a low boiling point itself, so it will vaporize at room temperature, but the vaporization speed varies depending on the ambient temperature. However, in the present embodiment, it is input into the circular frame 42, and there is a thermal insulation cover 48 outside the circular frame 42, which causes the temperature inside the circular frame 42 to be lower than the room temperature, so that the time it exists in the liquid state will be prolonged, which can speed up the absorption of heat at the bottom of the feeding cavity 2, so that the feeding cavity 2 forms a low-temperature zone 300, and the rotation generates centrifugal force and friction heat, so that the medium-temperature zone 400 can be formed.

[0038] It should also be noted that, in this embodiment, the low-boiling-point liquid refrigerant may be liquid propylene or liquid ammonia, which has a relatively high boiling point and therefore evaporates relatively slowly at room temperature. It is also inexpensive and does not cause much pollution.

[0039] Specifically, the bottom cooling device 4 also includes a gear sleeve 45 fixedly mounted on the outside of the circular frame 42 and passing through the outer shell 41, and a motor 47 fixedly mounted on the frame 1, and a gear 46 meshing with the gear sleeve 45 is fixedly mounted on the output end of the motor 47. A thermal insulation cover 48 is provided outside the outer shell 41, and the thermal insulation cover 48 is fixedly connected to the upper and lower sides of the outer shell 41, and the gear sleeve 45 is located inside the thermal insulation cover 48.

[0040] The starter motor 47 drives the gear 46 to rotate, which can mesh with the circular frame 42 brought by the gear sleeve 45 to rotate quickly, thereby accelerating the dispersion and vaporization of the low-boiling-point liquid refrigerant in the circular frame 42.

[0041] Specifically, the central cooling device 5 is provided with a fanning assembly 6, which includes a plurality of anti-corrosion fan-shaped plates 61 equidistantly distributed from top to bottom in the cooling chamber 52, and also includes a driving rod 62 for pushing the anti-corrosion fan-shaped plate 61 to shake, one end of the anti-corrosion fan-shaped plate 61 is hinged to the driving rod 62, and the other end is hinged to the inner wall of the arc-shaped thermal insulation shell 51, and a support member 65 is embedded in the inner wall of the arc-shaped thermal insulation shell 51, one end of the driving rod 62 is fixedly connected to the support member 65, and the other end is fixedly installed with a first protrusion 63, and a plurality of second protrusions 64 adapted to the first protrusion 63 are fixedly installed in the circular frame 42.

[0042] The second protrusion 64 rotates by rotating the circular frame 42. The rotation of the second protrusion 64 squeezes the first protrusion 63 to push the driving rod 62 upward, thereby driving the anti-corrosion fan plate 61 to swing up and down, so that the vaporized low-boiling point liquid refrigerant is blown into the cooling chamber 52, so that the feeding chamber 2 is cooled to form a medium temperature zone 400.

[0043] Specifically, the support member 65 includes a mounting tube 651 embedded in the inner wall of the arc-shaped thermal insulation shell 51 , one end of the driving rod 62 is slidably mounted in the mounting tube 651 , and a spring 652 is fixedly mounted between the driving rod 62 and the mounting tube 651 .

[0044] When the second protrusion 64 pushes the first protrusion 63, the driving rod 62 rises and moves in the installation tube 651 and the compression spring 652 contracts. When the second protrusion 64 passes, the driving rod 62 drops rapidly due to the rebound force of the spring 652, thereby causing the anti-corrosion fan plate 61 to swing up and down.

[0045] It should be noted that, in this embodiment, a fixing sleeve 8 is fixedly installed on the bottom of the frame 1, and an anti-corrosion friction plate 7 located in the circular frame 42 is fixedly installed on the fixing sleeve 8. The driving rod 62 passes through the fixing sleeve 8. Through the installation of the anti-corrosion friction plate 7, when the circular frame 42 rotates, the liquefied nitrogen and the anti-corrosion friction plate 7 can be strongly contacted to generate friction, thereby accelerating the vaporization of the low-boiling point liquid refrigerant, and the driving rod 62 passes through the fixing sleeve 8, which has a stabilizing and guiding effect on the driving rod 62, and the circular frame 42 and the frame are fixedly installed. 1 and the shell 41 are provided with sealing members, the sealing members include sealing rings and sealing pads (not shown in the figure), so as to ensure that the low-boiling-point liquid refrigerant will not leak. The shell 41 is provided with a circular slide 43, the circular frame 42 is fixed with a slide seat 44 that is slidably connected to the circular slide 43, the circular frame 42 includes an infusion port 200 arranged on the shell 41, and the arc-shaped temperature-insulating shell 51 is provided with a pressure relief port 100, and the low-boiling-point liquid refrigerant is input into the circular frame 42 through the infusion port 200, and the pressure can be relieved through the pressure relief port 100.

[0046] refer to Figure 7 It should also be noted that, in the present embodiment, the cap body feeding mechanism 9 comprises a plurality of seat bodies 91 and sealing seats 94, the seat bodies 91 are mounted on the sealing seats 94, a table top 96 is fixedly mounted on the frame body 1, a plurality of positioning grooves 97 adapted to the sealing seats 94 are provided on the table top 96, the seat body 91 is located above the positioning grooves 97, an electric cylinder 10 for pushing the sealing seats 94 upward is fixedly mounted at the bottom of the frame body 1, and a nail body feeding device 12 is also mounted on the top of the frame body 1.

[0047] The electric cylinder 10 pushes the sealing seat 94 upward, which will push the seat body 91 into the corresponding feeding cavity 2. With continuous pushing, the sealing seat 94 will be located at the bottom of the feeding cavity 2 to seal it, ensuring that the low temperature zone 300 of the feeding cavity 2 does not exchange heat with the external air.

[0048] Specifically, the seat body 91 is provided with a placement groove 92 for placing the cap body, the bottom of the seat body 91 is provided with an insertion rod 93, the top of the sealing seat 94 is provided with a slot 95 adapted to the insertion rod 93, and a push rod 98 is fixedly installed at the bottom of the sealing seat 94. Several push rods 98 are fixedly connected by a connecting plate 99, the pushing end of the electric cylinder 10 is fixedly connected to the connecting plate 99, and guide rods 11 are installed on both sides of the frame 1, and the guide rods 11 pass through both sides of the connecting plate 99.

[0049] During the specific body operation, the glue-coated cap body is placed in the placement groove 92, and then several seat bodies 91 are uniformly placed above the corresponding positioning grooves 97, and the insertion rod 93 is inserted into the slot 95 to connect the seat body 91 and the sealing seat 94, and then the electric cylinder 10 is started to push the push rod 98 to rise, so that the sealing seat 94 enters the bottom of the feeding cavity 2, and then wait for the nail body to be loaded. When the cap body and the nail body are bonded, the electric cylinder 10 is started again to push the push rod 98 to make the seat body 91 continue to rise.

[0050] And in this embodiment, it should be noted that the existing nail body and cap body are loaded by two separate loading devices and finally glued. In this solution, the problem of loading the cap body is mainly explained, so the nail body loaded by external loading equipment is not described in detail.

[0051] The present invention also discloses an automatic feeding method based on round cap paper nail processing, comprising the following steps:

[0052] S1: Start the bottom cooling device 4, form a low temperature zone 300, a medium temperature zone 400 and a normal temperature zone 500 on the feeding cavity 2, input low boiling point liquid refrigerant into the circular frame 42 through the infusion port 200, under the effect of time, the low boiling point liquid refrigerant absorbs the heat at the bottom of the feeding cavity 2, forming the low temperature zone 300, start the motor 47 to drive the circular frame 42 to rotate quickly, so that the low boiling point liquid refrigerant accelerates the vaporization and forms centrifugal force, the low boiling point liquid refrigerant is dispersed, and the low boiling point liquid refrigerant vaporized into water rises to the cooling cavity 52 to absorb the heat of the feeding cavity 2 there, thereby forming the medium temperature zone 400, and the top of the feeding cavity 2 is exposed to the room temperature environment in summer, forming the normal temperature zone 500;

[0053] S2: Place the cap body, place the cap body coated with glue on the seat body 91, and then insert the seat body 91 into the sealing seat 94, start the electric cylinder 10 to push the seat body 91 with the push rod 98 to rise, and the placement groove 92 will be inserted into the bottom of the feeding cavity 2 to form a seal. The cap body coated with glue is located in the low temperature area 300 of the feeding cavity 2 to prevent the glue from solidifying quickly under the room temperature environment in summer. Thus, the loading of the cap body is completed, and then wait for the loading of the external nail body;

[0054] S3: The cap body and the nail body are glued together, and the electric cylinder 10 is started again to push the push rod 98 to rise in the feeding cavity 2. The cap body will move to the medium temperature zone 400, where the temperature is still relatively low, which can prevent the glue from solidifying during the movement. As the cap body continues to rise, it enters the normal temperature zone 500, and the nail body is delivered to the normal temperature zone 500 of the feeding cavity 2 through the feeding device of the nail body. The two are pushed by external force to be glued together. At this time, the glue is in the normal temperature zone 500 under the room temperature environment in summer, which will make the glue solidify quickly, and the cap body and the nail body are combined, and finally the nail is removed.

[0055] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The automatic feeding equipment based on round cap paper nail processing according to claim 6 is characterized in that: The seat body (91) is provided with a placement groove (92) for placing the cap body, the bottom of the seat body (91) is provided with an insertion rod (93), the top of the sealing seat (94) is provided with a slot (95) adapted to the insertion rod (93), a push rod (98) is fixedly installed at the bottom of the sealing seat (94), a plurality of push rods (98) are fixedly connected via a connecting plate (99), the push end of the electric cylinder (10) is fixedly connected to the connecting plate (99), and guide rods (11) are installed on both sides of the frame body (1), and both sides of the connecting plate (99) penetrate the guide rods (11).

8. An automatic feeding method based on round cap paper nail processing, using the automatic feeding device based on round cap paper nail processing according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1: starting the bottom cooling device (4) to form a low temperature zone (300), a medium temperature zone (400) and a normal temperature zone (500) on the feeding cavity (2); inputting a low boiling point liquid refrigerant into the circular frame (42) through the infusion port (200); under the effect of time, the low boiling point liquid refrigerant absorbs the heat at the bottom of the feeding cavity (2), forming the low temperature zone (300); starting the motor (47) to drive the circular frame (42) to rotate rapidly, so that the low boiling point liquid refrigerant is accelerated to vaporize and form centrifugal force, the low boiling point liquid refrigerant is dispersed, and the low boiling point liquid refrigerant that has been vaporized into water rises into the cooling cavity (52) to absorb the heat of the feeding cavity (2) there, thereby forming the medium temperature zone (400); the top of the feeding cavity (2) is exposed to the room temperature environment in summer, forming the normal temperature zone (500); S2: placing the cap body, placing the cap body coated with glue on the seat body (91), and then inserting the seat body (91) into the sealing seat (94), starting the electric cylinder (10) to push the seat body (91) with the push rod (98) to rise, and the placement groove (92) will be inserted into the bottom of the feeding cavity (2) to form a seal. The cap body coated with glue is located in the low temperature zone (300) of the feeding cavity (2) to prevent the glue from solidifying quickly under the room temperature environment in summer. Thus, the loading of the cap body is completed, and then wait for the loading of the external nail body; S3: The cap body and the nail body are glued together. The electric cylinder (10) is started again to push the push rod (98) upward in the feeding chamber (2). The cap body moves into the medium temperature zone (400°C). The temperature there is still relatively low, which can prevent the glue from solidifying during the movement. As the cap body continues to rise, it enters the normal temperature zone and is delivered to the normal temperature zone of the feeding chamber (2) by the feeding device of the nail body. The two are pushed together by external force. At this time, the glue is in the normal temperature zone (500°C) under the room temperature environment in summer, which will cause the glue to solidify quickly. The cap body and the nail body are combined, and finally the nail is removed.
