Description

Technical Field

[0001] The present application relates to the technical field of shoemaking machinery, and in particular to a trimming device for processing soles used in shoe production. Background Art

[0002] The sole production process mainly includes the following: cold bonding process, injection molding process and vulcanization process. Among them, injection molding process is widely used in sole production due to its advantages such as fast production speed and diversified molding. Injection molding process is to use a machine to tie the upper on the aluminum sandalwood, and generally directly inject PVC, TPR and other materials by a turntable machine to form the sole in one go. Now there is also PU (chemical name polyurethane) injection molding (the machine and mold are different from general injection molding), which has the characteristics of being odorless, low-priced, elastic, not hard at low temperatures, comfortable to wear, light and durable.

[0003] During the production process, in order to ensure that the sole can be completely formed, a sufficient amount of material is generally injected into the mold. Therefore, a small amount of material will overflow from the molded sole at the mold closing position, thereby generating flash. In order to improve the aesthetics of the product and facilitate subsequent processing, the flash needs to be cut off. On the one hand, traditional trimming operators rely on experience, and the trimming accuracy is unstable. On the other hand, existing trimming machine equipment requires manual fixation and release of the sole, and the degree of automation and production efficiency are low. In addition, the waste collection efficiency in the existing technology is low, resulting in a poor production environment and is not conducive to the health of workers.

[0021] Compared with the prior art, the advantages of this application are:

[0022] (1) By setting a positioning member, the positioning member includes a rotating guide plate 1 and a rotating guide plate 2. Due to the effect of gravity, the guide plates 1 and 2 are always facing downward. The lower guide plates 1 and 2 are facing the sole. At this time, the guide plates 1 and 2 act as clamps and can correct the position of the sole to the center. The upper guide plates 1 and 2 are away from the sole. At this time, the guide plates 1 and 2 act as guides and can guide the cut waste and assist in collecting the waste. The functions of the guide plates 1 and 2 at different workstations can be automatically switched, thereby improving the flexibility and practicality of the device.

[0023] (2) By setting positioning pieces on the guide plate 1 and the guide plate 2, the lower guide plate 1 and the guide plate 2 face the sole. At this time, the guide plate 1 and the guide plate 2 act as clamps. Under the gravity of the slider and the extrusion plate, the extrusion plate and the slider move toward the middle, so that all the extrusion plates move toward the sole. Under the gravity of the extrusion plate, the sole is located in the middle position of the mounting plate, thereby realizing the preliminary positioning of the sole.

[0024] (3) By setting the adsorption part, the electric telescopic rod is started, driving the lifting plate and the piston rod to descend at the same time. The piston rod descends and squeezes the air in the piston cylinder into the inside of the slider through the ventilation pipe, thereby pushing the extrusion plate to extend, further squeezing the sole, so that the sole can be more accurately located in the middle of the mounting plate, thereby further positioning the sole. After the lifting plate descends a certain distance, the suction cup contacts and squeezes the sole. At this time, the adsorption switch also squeezes the sole, so that the adsorption switch is closed, the negative pressure device is started, and the sole is firmly adsorbed, so that the sole can be taken out.

[0025] (4) By setting up a waste collection piece, the upper guide plates 1 and 2 are directed away from the sole and obliquely downward. At this time, the guide plates 1 and 2 act as guide plates. The waste generated by trimming falls into the collection frame for collection under the guidance of the guide plates 1, 2, the splicing plate, the guide bridge and the guide rack. The guide plates 1, 2 and the splicing plate completely surround the sole, thereby preventing the waste from leaking out and realizing comprehensive collection of the waste. Under the action of the gravity block, the collection frame has a lower center of gravity, and the entrance position of the collection frame can always be kept upward during the rotation process to prevent the waste from spilling out.

[0026] (5) By making the slider and the extrusion plate from high-density materials with high density, high mass and high weight, under the action of the gravity of the slider and the extrusion plate, the guide plates 1 and 2 can be assisted to move quickly downward during the rotation process, and all the extrusion plates can be driven to move toward the sole, thereby correcting the deviation of the sole.

[0027] (6) By connecting a plurality of vent pipes to a piston cylinder, one vent pipe is connected to a slider, so that the inside of the sliders on the guide plate 1 and the guide plate 2 can be inflated at the same time, so that the extrusion plates on the guide plate 1 and the guide plate 2 extend synchronously, thereby realizing the center positioning of the sole.

[0028] (7) By arranging a splicing plate between the guide plate 1 and the guide plate 2, the splicing plate can fill the gap between the guide plate 1 and the guide plate 2, thereby preventing waste from falling onto the equipment through the gap between the guide plate 1 and the guide plate 2, thereby making waste collection more comprehensive.

[0029] (8) By providing the limit groove and the limit block, the limit block and the limit groove can limit the rotation of the guide clamping plate 1 and the guide clamping plate 2, thereby realizing the limitation of the rotation angle of the guide clamping plate 1 and the guide clamping plate 2.

[0030] (9) By setting an elastic lifting platform and a handle, the handle is pressed to drive the platform down, the sole is placed on the platform, and then the handle is released, and the platform is driven up and reset under the elastic force of the elastic telescopic rod to achieve loading.

Under the gravity of the slider 901 and the extrusion plate 902, the guide plate 1 603 and the guide plate 2 604 can be assisted to move quickly downward during the rotation process, and all the extrusion plates 902 can be driven to move toward the sole, thereby correcting the deviation of the sole, the piston cylinder 903 is fixedly connected to the mounting platform 5, and the piston rod 904 is sealed and slidably connected to the piston cylinder 903 Then, one end of the piston rod 904 located on the outside of the piston cylinder 903 is fixedly connected to the lifting plate 702, and the ventilation pipe 905 is fixedly connected between the slider 901 and the piston cylinder 903 to connect the slider 901 with the piston cylinder 903. The material of the ventilation pipe 905 is rubber, which can adapt to the rotation of the guide clamp plate 1 603 and the guide clamp plate 2 604.

[0047] The guide plate 1 603 and the guide plate 2 604 below are facing the sole. At this time, the guide plate 1 603 and the guide plate 2 604 act as clamps. Under the gravity of the slider 901 and the extrusion plate 902, the extrusion plate 902 and the slider 901 move toward the middle, so that all the extrusion plates 902 move toward the sole. Under the gravity extrusion of the extrusion plate 902, the sole is located in the middle position of the mounting plate 602, thereby realizing the preliminary positioning of the sole.

[0048] An adsorption member 7 is provided in the middle of the positioning member 6, and the adsorption member 7 includes an electric telescopic rod 701, a lifting plate 702, a suction cup 703 and an adsorption switch 704; the electric telescopic rod 701 is fixedly connected to the mounting platform 5, the lifting plate 702 is fixedly connected to the output end of the electric telescopic rod 701, the lifting plate 702 is slidably connected to the lifting hole 605, a plurality of suction cups 703 are provided and evenly distributed and installed on a side of the lifting plate 702 away from the electric telescopic rod 701, a plurality of suction cups 703 are connected to the negative pressure device (the negative pressure device is a prior art, not shown in the figure, and will not be elaborated on here), and the adsorption switch 704 is provided in the middle of the lifting plate 702.

[0049] The electric telescopic rod 701 is started, driving the lifting plate 702 and the piston rod 904 to descend at the same time. The piston rod 904 descends to squeeze the air in the piston cylinder 903 into the inside of the slider 901 through the ventilation pipe 905, thereby pushing the squeezing plate 902 to extend, further squeezing the sole, so that the sole can be more accurately located in the middle of the mounting plate 602, thereby further positioning the sole.

A splicing plate 12 is fixedly connected to the mounting plate 602. There are multiple splicing plates 12 and they are located between the guide plate 1 603 and the guide plate 2 604. The splicing plates 12 can fill the gap between the guide plate 1 603 and the guide plate 2 604 to prevent waste from falling onto the equipment through the gap between the guide plate 1 603 and the guide plate 2 604, thereby making waste collection more comprehensive.

[0051] The upper guide plate 1 603 and guide plate 2 604 are facing obliquely downward away from the sole. At this time, guide plate 1 603 and guide plate 2 604 act as guide plates. The waste generated by trimming falls into the collection frame 803 for collection under the guidance of guide plate 1 603, guide plate 2 604, splicing plate 12, guide bridge 805 and guide rack 802. Guide plate 1 603, guide plate 2 604 and splicing plate 12 completely surround the sole, thereby preventing the waste from leaking and achieving comprehensive collection of the waste. Under the action of gravity block 804, the center of gravity of the collection frame 803 is relatively low, so that the entrance position of the collection frame 803 can always be facing upward during the rotation process to prevent the waste from spilling.

[0052] A limiting groove 10 is provided on both the guide clamp plate 1 603 and the guide clamp plate 2 604, and the side wall of the mounting plate 602 is fixedly connected to a limiting block 11, and a plurality of limiting blocks 11 are provided.

[0053] An elastic telescopic rod 13 is fixedly connected in the middle of the workbench 1 , a placing platform 14 is fixedly connected to the upper end of the elastic telescopic rod 13 , and handles 15 are fixedly connected to both sides of the placing platform 14 .

[0054] The handle 15 is pressed to drive the placing platform 14 to descend, and the sole is placed on the placing platform 14 . Then, the handle 15 is released, and the placing platform 14 is driven to ascend and reset under the elastic force of the elastic telescopic rod 13 to achieve loading.

[0055] Working principle: Start the motor 2 to drive the rotating rod 4 to rotate to a vertical state, press the handle 15 to drive the placement table 14 to descend, place the sole on the placement table 14, and then release the handle 15. Under the elastic force of the elastic telescopic rod 13, the placement table 14 is driven to rise and reset to achieve loading;

[0056] At this time, the guide plate 1 603 and the guide plate 2 604 at the bottom face the sole, and the guide plate 1 603 and the guide plate 2 604 act as clamps. Under the gravity of the slider 901 and the extrusion plate 902, the extrusion plate 902 and the slider 901 move toward the middle, so that all the extrusion plates 902 move toward the sole. Under the gravity extrusion of the extrusion plate 902, the sole is located in the middle of the mounting plate 602, thereby achieving preliminary positioning of the sole position;

[0057] Then, the electric telescopic rod 701 is started, driving the lifting plate 702 and the piston rod 904 to descend at the same time. The piston rod 904 descends to squeeze the air in the piston cylinder 903 into the inside of the slider 901 through the ventilation pipe 905, thereby pushing the squeezing plate 902 to extend, further squeezing the sole, so that the sole can be more accurately located in the middle of the mounting plate 602, and further positioning the sole position is achieved. After the lifting plate 702 descends a certain distance, the suction cup 703 contacts and squeezes the sole, and at this time, the adsorption switch 704 also squeezes the sole, so that the adsorption switch 704 is closed, and the negative pressure device is started to firmly adsorb the sole, so that the sole can be taken out;

[0058] After that, the motor 2 rotates to drive the adsorbed sole to rotate upward, and the guide plate 1 603 and the guide plate 2 604 rotate upward and away from the sole toward obliquely downward. At this time, the guide plate 1 603 and the guide plate 2 604 act as guide plates, and the waste generated after the sole trimming is guided by the guide plate 1 603, the guide plate 2 604, the splicing plate 12, the guide bridge 805 and the guide rack 802 to fall into the collection frame 803 for collection. The guide plate 1 603, the guide plate 2 604 and the splicing plate 12 completely surround the sole, thereby preventing the waste from leaking out and realizing comprehensive collection of the waste. Under the action of the gravity block 804, the center of gravity of the collection frame 803 is relatively low, so that the entrance position of the collection frame 803 can always be upward during the rotation process to prevent the waste from spilling out.

[0059] After the trimming is completed, the negative pressure device is powered off, the fixation of the sole is released, and the sole is removed (the trimming tool in this application can move up, down, left, right, forward and backward according to the trimming position. This is the prior art and will not be elaborated on here).

[0060] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and its improved conception, which should be covered by the protection scope of the present application.
