Description

Technical Field

[0001] The utility model relates to the technical field of spectacle case processing, and particularly relates to a spectacle case pressing machine. Background Art

[0002] The processing inside the spectacle case needs to be carried out by a hot press, while the sides need to be processed by a hot stamping machine to complete the overall processing of the spectacle case. At the same time, it is also necessary to collect the processed spectacle cases to prevent them from being scattered.

[0003] Although the existing spectacle case pressing machines can achieve the pressing of spectacle cases, they do not have the functions of precise automatic pressing, hot stamping, and collecting processed spectacle cases at the same time. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a spectacle case pressing machine with a simple structure, high automation degree, and capable of simultaneously realizing precise pressing, hot stamping, and collecting of spectacle cases in view of the above-mentioned deficiencies of the prior art.

[0005] To achieve the above object, the following technical solution is adopted. A spectacle case pressing machine includes a conveyor belt, a workbench, and a pressing mechanism. A transmission mechanism with a transmission direction perpendicular to that of the conveyor belt is provided on the workbench. The transmission mechanism includes a support seat provided on the workbench and a sensing member provided on the support seat. A guide rail perpendicular to the conveyor belt transmission direction is provided on the side of the support seat facing the conveyor belt. A transmission member that slides from end to end along the guide rail when the sensing member works is provided on the guide rail. A transmission baffle is provided on the side of the transmission member facing the pressing mechanism. The pressing mechanism is located at the end of the guide rail. The pressing mechanism includes a pressing base and at least two hot pressing members that are lifted and lowered and extend out of the pressing base on the workbench. A positioning mechanism is fixedly provided on the workbench above the hot pressing members. The positioning mechanism includes a first positioning plate that is lifted and lowered above one of the hot pressing members and a second positioning plate that elastically clamps and senses the spectacle case above the other hot pressing member. A hot stamping member driven obliquely by a cylinder is provided on the workbench facing the first positioning plate. When the top of the hot stamping member extends out, it is located between the first positioning plate and the hot pressing member to perform hot stamping on the spectacle case. When the second positioning plate elastically clamps and senses the spectacle case, the first positioning plate presses down to position the spectacle case and cooperates with the hot pressing member to perform hot pressing on the internal space of the spectacle case, and the hot stamping member obliquely extends out to perform hot stamping on the spectacle case.

[0006] With the above technical solution, when the conveyor belt transports the spectacle case to the workbench, the sensing part senses the spectacle case. At this time, the transmission part sends the spectacle case to the pressing mechanism through the transmission baffle, and through the continuous operation of the transmission part, the spectacle cases at the back continuously push the spectacle cases in front, so as to realize the step-by-step movement of the spectacle cases. The spectacle cases are in an open state and are transported on the conveyor belt with the internal space facing downwards. The second positioning plate is elastically abutted above the spectacle case (that is, the outer shell of the spectacle case) through a spring and a rod, and the second positioning plate can send a signal to the first positioning plate when it elastically presses the spectacle case by setting a sensor. The first positioning plate is controlled to lift and lower by a cylinder. When the second positioning plate senses the spectacle case, the first positioning plate is controlled by the cylinder to descend and press the spectacle case. At this time, the pressing part below also extends upward from the pressing base and hot-presses the internal space of the spectacle case, making the side for placing glasses inside the spectacle case fit more tightly. When the spectacle case is hot-pressed, the labeling part also extends obliquely through the cylinder and adheres to the side surface of the outer surface of the spectacle case to complete labeling. After labeling is completed, the labeling part retracts again, the pressing part also descends to stop pressing, and the first positioning plate is also controlled by the cylinder to lift upward again. The spectacle cases at the back are pushed by the transmission baffle to push the spectacle cases in front to the next process, thus realizing automatic hot-pressing and labeling.

[0007] A spectacle case pressing machine can be further set as follows: The positioning mechanism further includes a positioning clip member that can expand or contract and is located at the bottom of the spectacle case on the side away from the transmission part, and a guide rod fixed on the pressing base for guiding the transmission of the spectacle case and positioning the spectacle case.

[0008] With the above technical solution, after the spectacle case goes through the hot-pressing and labeling processes, it enters the process of collecting the spectacle cases. The guide rod can extend into the center of the opening and closing of the spectacle case to keep the spectacle case in a straight line during guiding. When the positioning clip member is at the bottom position of the spectacle case, the guide rod is just used for positioning the spectacle case to prevent the spectacle case from being pushed out excessively. At this time, the positioning clip member is in a contracted state, so the spectacle case will not fall. When the positioning clip member expands, the spectacle case will fall to the designated position, thus realizing the collection of the spectacle cases.

[0009] A spectacle case pressing machine can be further set as follows: The positioning clip member includes a two-way cylinder and clamping claws arranged on both sides of the two-way cylinder. A slot smaller than the spectacle case is formed on the opposite side of the clamping claws.

[0010] With the above technical solution, the two-way cylinder enables the clamping claws to contract or expand simultaneously. The slot will not interfere with the falling of the spectacle case when the clamping claws open, making the storage of the spectacle case more convenient.

[0011] A spectacle case pressing machine can be further configured as follows: a positioning rod is further provided on the pressing base, and a positioning stop is provided on the positioning rod, which clamps the upper end of the spectacle case when the spectacle case is located above the positioning clip.

[0012] With the above technical solution, the positioning stop can clamp the spectacle case downward through its own deformation. An inductor can also be provided on the positioning stop. When it clamps the spectacle case, a signal is transmitted to the positioning clip through the inductor, so that the positioning clip is loosened, and then it falls into the set position, thus realizing directional collection.

[0013] A spectacle case pressing machine can be further configured as follows: a rotatable storage tray is provided below the positioning stop, and a number of pairs of limiting rods are circumferentially provided on the storage tray. Each group of limiting rods passes through the notch of the spectacle case and positions the spectacle case.

[0014] With the above technical solution, after the spectacle case is opened, it is in the form of two connected sheets. Through the paired limiting rods on the storage tray, the two limiting rods just pass through the head and tail ends of the two connected positions after the spectacle case is opened, thus realizing two-point positioning. And the storage tray can be controlled to rotate by a motor. An inductor can also be provided at the top of the limiting rod. When the inductor senses the spectacle case, it can rotate automatically. The limiting rods can be set in four groups, so that four spectacle cases can be stored simultaneously without interference.

[0015] A spectacle case pressing machine can be further configured as follows: one end of the positioning rod facing the transmission part is spiky, and the other end is hook-shaped and hooks at the notch of the spectacle case to keep the spectacle case always above the positioning clip.

[0016] With the above technical solution, when one end of the positioning rod facing the transmission part is set to be spiky, it is to play a role in guiding the spectacle case, while the other end being hook-shaped is to play a role in positioning the spectacle case. Through the hook-shaped setting, the spectacle case can be prevented from being pushed out excessively, so that the falling position of the spectacle case is always kept in a controllable position.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment: As shown in Figures 1-6A spectacle case pressing machine shown in the figure includes a conveyor belt 1, a workbench 2 and a pressing mechanism 3. A transmission mechanism 4 with a transmission direction perpendicular to that of the conveyor belt 1 is provided on the workbench 1. The transmission mechanism 4 includes a support base 41 provided on the workbench 1 and a sensing member 42 provided on the support base 41. A guide rail 43 perpendicular to the transmission direction of the conveyor belt 1 is provided on one side of the support base 41 facing the conveyor belt 1. A transmission member 44 that slides from end to end along the guide rail 43 when the sensing member works is provided on the guide rail 43. A transmission baffle 45 is provided on one side of the transmission member 44 facing the pressing mechanism 3. The pressing mechanism 3 is located at the tail of the guide rail 43. The pressing mechanism 3 includes a pressing base 31 and at least two hot pressing members 32 that are lifted and lowered on the workbench 1 and extend out of the pressing base 31. A positioning mechanism 5 is fixedly provided on the workbench 1 above the hot pressing members 32. The positioning mechanism 5 includes a first positioning plate 51 that is lifted and lowered above one of the hot pressing members 32 and a second positioning plate 52 that is elastically clamped above the other hot pressing member 32 and senses the spectacle case. A hot stamping member 53 driven obliquely by a cylinder is provided on the workbench 1 facing the first positioning plate 51. When the hot stamping member 53 extends out, it is located between the first positioning plate 51 and the hot pressing member 32. When the second positioning plate 52 elastically clamps and senses the spectacle case, the first positioning plate 51 presses down to position the spectacle case and cooperates with the hot pressing member 32 to realize hot pressing the inner space of the spectacle case. The top of the hot stamping member 53 extends obliquely to perform hot stamping on the spectacle case. When the conveyor belt 1 conveys the spectacle case to the workbench 2, the sensing member 42 senses the spectacle case. At this time, the transmission member 44 sends the spectacle case to the pressing mechanism 3 through the transmission baffle 45. And through the continuous work of the transmission member 44, the spectacle cases behind continuously push the spectacle cases in front, so as to realize the step-by-step progress of the spectacle cases, as Figure 5 shown. The spectacle case is in an open state and is conveyed on the conveyor belt 1 with its inner space facing downwards. The second positioning plate 52 is elastically abutted above the spectacle case (i.e., the outer shell of the spectacle case) through a spring and a rod. And the second positioning plate 52 can send a signal to the first positioning plate 51 when it elastically presses the spectacle case by setting a sensor. The first positioning plate 51 is controlled to lift and lower by a cylinder. When the second positioning plate 52 senses the spectacle case, the first positioning plate 51 is controlled by the cylinder to descend and press the spectacle case. At this time, the hot pressing members 32 below also extend out from the pressing base 31 and push up to hot press the inner space of the spectacle case, making the side for placing glasses inside the spectacle case fit more tightly. When the spectacle case is hot pressed, the hot stamping member 53 also extends obliquely through the cylinder at this time and fits on the side surface of the outer surface of the spectacle case to complete hot stamping. After hot stamping is completed, the hot stamping member 53 retracts again, the hot pressing members 32 also descend to stop hot pressing, and the first positioning plate 51 is also controlled by the cylinder to lift up again. And the spectacle cases behind are pushed by the transmission baffle 45 to push the spectacle cases in front to the next process, thus realizing automatic hot pressing and hot stamping.

[0027] The positioning mechanism 5 further includes a positioning clip 54 disposed on the side of the ironing member 32 away from the transmission member 44, which can expand or contract and is located at the bottom of the spectacle case, and a guide rod 55 fixed on the pressing base 31 for guiding the transmission of the spectacle case and positioning the spectacle case. The positioning clip 54 includes a two-way cylinder 541 and clamping jaws 542 disposed on both sides of the two-way cylinder 541. A slot 543 smaller than the spectacle case is formed on the opposite side of the clamping jaws 542. The clamping jaws 542 do not interfere with the falling of the spectacle case after being opened through the slot 543, and can be synchronously contracted or expanded through the two-way cylinder 541. One end of the guide rod 55 facing the transmission member is spiky, and the other end is hooked at the notch of the spectacle case so that the spectacle case is always located above the positioning clip 54. A positioning rod 56 is further disposed on the pressing base 31, and a positioning stop 57 for clamping the upper end of the spectacle case when the spectacle case is located above the positioning clip 54 is disposed on the positioning rod. A rotatable storage tray 58 is disposed below the positioning stop 57. A number of pairs of limiting rods 59 are circumferentially disposed on the storage tray 58. As Figure 5 and Figure 6 shown, each group of limiting rods 59 passes through the notch of the spectacle case and positions the spectacle case. After the spectacle case is opened, it is in the form of two connected sheets. Through the paired limiting rods 59 on the storage tray 58, the two limiting rods 59 just pass through the head and tail ends of the two connected positions after the spectacle case is opened, so as to achieve two-point limiting. Moreover, the storage tray 58 can be controlled to rotate by a motor, and sensors can also be disposed at the tops of the limiting rods 59. When the sensors sense the spectacle case, automatic rotation can be realized, that is, automatic rotation is realized after the spectacle case is full. The limiting rods 59 can be set to four groups, so that four spectacle cases can be stored simultaneously without interference.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
