Abstract

The present application belongs to the technical field of footwear manufacturing, and discloses a drying device for footwear production, which comprises a conveying mechanism and shoes, and further comprises: a heat preservation box arranged on the conveying mechanism, and a support fixed on the heat preservation box. Through the cooperation of the lining assembly and the shoe structure, the spring expansion plate clamps the tongue of the shoe, so that the steel ball cannot be squeezed out due to excessive shrinkage of the shoe.

Description

[0001] This invention belongs to the field of footwear manufacturing technology, specifically a drying equipment used in footwear production. Background Technology

[0002] Shoe manufacturing is a complex process involving materials science, engineering design, technological processes, and human expertise. The manufacturing details vary considerably between different types of shoes. It generally includes the production of the upper, sole, tongue, and laces. After all the structural components are assembled, drying equipment is typically used to remove excess moisture and accelerate glue curing, thereby improving the shoe's durability.

[0003] In existing technologies, shoes are typically placed directly into the equipment and the soles are fixed in place. However, it's important to note that the shoes lack linings, requiring workers to manually place shoe lasts inside. Since the internal space of each shoe is different, the same shoe last cannot be used for different shoe sizes. This necessitates the expenditure of resources and time to manufacture the appropriate shoe lasts before drying, and also requires manual labor to install them individually. Consequently, production capacity is reduced, leading to decreased efficiency of existing drying equipment. Summary of the Invention

DETAILED DESCRIPTION

[0041] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application.

[0042] As shown in Figures 1 to 12 The present application provides a drying device for shoe production, which comprises a conveying mechanism 1 and a shoe 7, and further comprises;

[0043] A heat preservation box 2 is arranged on the conveying mechanism 1, the heat preservation box 2 is fixed with a support 21, and a group of inner lining assemblies 5 are symmetrically arranged on the support 21;

[0044] The inner lining assembly 5 comprises a hydraulic rod two 51 fixed on the support 21, an end of the hydraulic rod two 51 is connected with a pressurizing cylinder 53 through a hydraulic rod three 52, the pressurizing cylinder 53 is movably clamped with a positioning cylinder 56 through a storage cylinder 55, the hydraulic rod three 52 and the storage cylinder 55 are connected through an elastic member one 54, and the storage cylinder 55 and the positioning cylinder 56 are filled with steel balls;

[0045] Two push plates 551 are symmetrically arranged on the outer periphery of the storage cylinder 55, two sliding plates 561 are symmetrically and slidably arranged on the outer periphery of the positioning cylinder 56, the upper and lower ends of the sliding plate 561 are respectively hinged with a pressurizing plate 563 and a spring telescopic plate 562, and the push plate 551 is slidably arranged on the pressurizing plate 563;

[0046] The bottom of the pressurizing cylinder 53 is connected with a rubber sleeve 58 through a steel cable 57, and the bottom of the rubber sleeve 58 is connected with the bottom of the positioning cylinder 56;

[0047] The drying device further comprises;

[0048] A limiting assembly 4 for fixing the shoe 7, and an infrared detection system 11 for detecting the position of the shoe 7;

[0049] A drying assembly 6 for drying the shoe 7, and a heat preservation assembly 3 for accelerating the temperature rise in the heat preservation box 2.

[0050] The above scheme is adopted: the drying assembly 6 is connected to the air outlet end of the fan system in priority, when the infrared detection system 11 detects that the shoe 7 is conveyed to a specified station by the conveying mechanism 1, the heat preservation assembly 3 is started, and the two ends of the heat preservation box 2 are closed, so as to ensure that the temperature in the heat preservation box 2 will not be quickly lost, and the limiting assembly 4 is used for fixing the shoe 7;

[0051] The hydraulic rod three 52 is then stretched, and the positioning cylinder 56 is in contact with the insole of the shoe 7. During this period, due to the elastic force of the elastic member one 54, the positioning cylinder 56 is preferentially retracted into the storage cylinder 55, and the steel cable 57 is gradually loosened. At the same time, the steel ball and part of the rubber sleeve 58 are pressed into the inside of the shoe 7, thereby playing the role of supporting the shoe 7. Since the steel ball is a rigid material and is limited by the pressing cylinder 53 at the top, when the shoe 7 shrinks due to heating, the steel ball can effectively prevent this situation from occurring.

[0052] During the process of the positioning cylinder 56 entering the inside of the storage cylinder 55, the sliding plate 561 is also lowered. Since the steel ball is gradually laid in the inside of the shoe 7 and is wrapped by the rubber sleeve 58, the end of the spring expansion plate 562 is limited by the steel ball, so it will be folded and located above the steel ball. Finally, the storage cylinder 55 pushes the pressing plate 563 to descend through the push plate 551, thereby clamping the tongue part of the shoe 7 together with the spring expansion plate 562, further limiting the position of the steel ball, so that it will not be squeezed out of the inside of the shoe 7 due to excessive shrinkage of the shoe 7.

[0053] At the same time, since the rubber sleeve 58 has stretchability, when the steel ball is located in the inside of the shoe 7, it can be wrapped by the rubber sleeve 58, so this supporting work can effectively be applied to different shoes 7 and adapt to the volume inside different specifications of shoes 7. The hardness of the steel ball can also easily cope with the pressure caused by shrinkage, and the strength of the support provided by the steel ball can also meet the needs of the production process.

[0054] It should be noted that since the shoe 7 enters the inside of the heat preservation box 2, it cannot be determined whether the toe or the heel enters first. In order to ensure that the tongue of the shoe 7 can be accurately fixed, the storage cylinder 55 and the positioning cylinder 56 have two sets of auxiliary structures for clamping on the periphery, and are symmetrically arranged. When one set can clamp, the other set faces the heel part of the shoe 7, but when the other set clamps, the end of the spring expansion plate 562 will be retracted, so that it will not be folded.

[0055] After the drying work is completed, the lining assembly 5 returns to the initial position, and the steel cable 57 pulls the rubber sleeve 58 and the steel ball back into the inside of the storage cylinder 55 and the positioning cylinder 56 through the pressing cylinder 53.

[0056] As shown in Figures 1-7 The bottom of the positioning cylinder 56 is symmetrically provided with two notches.

[0057] With the above scheme: after the positioning cylinder 56 is in contact with the insole part of the shoe 7, due to the guidance of the notches, the steel ball can smoothly enter the inside of the shoe 7, and force the spring expansion plate 562 to be folded, avoiding the situation that the spring expansion plate 562 cannot clamp the tongue part in time with the pressing plate 563.

[0058] The shoe mouth size of the shoe 7 is mostly similar, the outer diameter value of the positioning cylinder 56 can be as small as possible to improve the adaptability of the device, and the length of the positioning cylinder 56 and the storage cylinder 55 can be increased to ensure that the number of steel balls can still smoothly fill the work, thereby avoiding the reduction of the supporting performance.

[0059] As shown in Figures 1-6 The sliding plate 561 is connected between the pressing plate 563 through the elastic member two 564, the bottom bearing of the spring expansion plate 562 is provided with the rolling shaft 565, and the outer side of the positioning cylinder 56 is provided with the protrusion symmetrically.

[0060] By adopting the above scheme: when the steel ball enters the inside of the shoe 7, the rolling shaft 565 can roll on the rubber sleeve 58, so that the end of the spring expansion plate 562 does not hard contact work, and the situation that the rubber sleeve 58 is possibly pulled and dragged is reduced, thereby causing unnecessary wear of the rubber sleeve 58;

[0061] Since the elastic member two 564 can only slide up and down, when the spring expansion plate 562 descends, the distance between the hinge point and the protrusion increases, and the angle at which the rolling shaft 565 can be inclined also increases, which can further avoid the end of the spring expansion plate 562 from contacting the rubber sleeve 58 and pulling and dragging the rubber sleeve 58 through friction, thereby improving the service life of the rubber sleeve 58.

[0062] As shown in Figures 1-4 The limiting assembly 4 includes a hydraulic rod one 41 fixed to the side of the conveying mechanism 1, the end of the hydraulic rod one 41 is connected with a baffle one 42, the outer side of the baffle one 42 is connected with a baffle two 44 through the symmetrically arranged tension spring 43, and the tension spring 43 is movably connected with the baffle two 44.

[0063] By adopting the above scheme: when the infrared detection system 11 detects that the shoe 7 is located at the working position, the hydraulic rod one 41 drives the baffle one 42 to move, but the two baffle two 44 will preferentially contact, thereby preventing the shoe 7 from passing through the working position, and then the two baffle one 42 clamps the shoe 7, the tension spring 43 is pulled, and the bottom of the baffle two 44 is hollow, which can make the bottom of the shoe 7 also pass through the wind, which can shorten part of the drying time, and when the shoe 7 is fixed by the baffle one 42, the lining assembly 5 can more accurately perform the supporting work, thereby improving the drying quality of the device.

[0064] As shown in Figures 1-7 The infrared detection system 11 includes two infrared emitters and infrared receivers distributed above and below, each two limiting assemblies 4 form a group, and the number of the limiting assembly 4, the lining assembly 5 and the infrared detection system 11 correspond to each other.

[0065] When the infrared detection system 11 close to the outlet part of the heat preservation box 2 detects the shoe 7, the remaining infrared detection systems 11 start detection work in turn.

[0066] When the lower infrared detector detects the shoe 7 and the upper infrared detector detects the shoe 7 within a specified time, the shoe opening of the shoe 7 is in the same axis as the bottom of the positioning cylinder 56, and the hydraulic rod two 51 does not need to adjust the position of the hydraulic rod three 52;

[0067] When the upper and lower infrared detectors simultaneously detect the shoe 7, the shoe opening of the shoe 7 is not in the same axis as the bottom of the positioning cylinder 56, and the hydraulic rod two 51 needs to adjust the position of the hydraulic rod three 52 to force the bottom of the hydraulic rod three 52 to be in the same axis as the shoe opening of the shoe 7.

[0068] With the above scheme: as shown in Figure 7 The toe part of the shoe 7 is the direction of movement, that is, the conveying mechanism 1 controls the shoe 7 to move from right to left. When each shoe 7 is located on the conveying mechanism 1, a certain distance needs to exist and they cannot be close together.

[0069] When the shoe 7 moves to the leftmost side, the lower infrared detector in the infrared detection system 11 detects the shoe 7 first. Since the shoe opening part of the shoe 7 is usually higher than the vamp, the upper infrared detector detects the shoe 7 within a certain time, so the working position of the shoe 7 can match the inner lining assembly 5 in the initial state, and the limiting assembly 4 can start and intercept and fix the shoe 7.

[0070] When the two infrared detectors simultaneously detect the object, it means that the heel part of the shoe 7 is facing the advancing direction, and at this time the hydraulic rod two 51 needs to be stretched to align the shoe opening part of the shoe 7 with the bottom structure of the hydraulic rod three 52, which effectively improves the intelligence of the device and makes the worker place the shoe 7 without needing to spend extra effort to pay attention to the direction.

[0071] As shown in Figures 1-9 The heat preservation assembly 3 includes a double-shaft motor 31 fixed to the corners of the heat preservation box 2 and a conveying shaft 32 rotatably installed at the remaining corners of the heat preservation box 2. The output shaft of the double-shaft motor 31 drives each conveying shaft 32 to rotate through a transmission belt 33. A push rod 34 is movably connected to both ends of the double-shaft motor 31 and the conveying shaft 32. The push rod 34 is screw-connected to the heat preservation box 2. A heat preservation plate 35 is symmetrically hinged to the two sides of the heat preservation box 2. Each two horizontally arranged push rods 34 are slidingly connected to the heat preservation plate 35.

[0072] The heat preservation assembly 3 is located inside the heat preservation box 2, and each heat preservation plate 35 is provided with a slot for the conveying mechanism 1 to pass through.

[0073] When each shoe 7 is dried, the double-shaft motor 31 drives the conveying shaft 32 to rotate through the transmission belt 33, the conveying shaft 32 drives the pushing rod 34 to rotate, and the pushing rod 34 supports the heat preservation plate 35 outward through the thread design, so that the heat preservation plate 35 no longer blocks the end of the heat preservation box 2, and the conveying mechanism 1 can move a new batch of shoes 7 into the heat preservation box 2;

[0074] When the heat preservation plate 35 closes the heat preservation box 2, a gap still exists between the two, the air discharged by the drying assembly 6 can flow, but most of the hot air is blocked, thereby accelerating the temperature rise in the heat preservation box 2, and shortening the drying time;

[0075] And this can also effectively reduce the probability of external foreign matter entering the heat preservation box 2 and interfering with the drying work.

[0076] As shown in Figures 1-12 The drying assembly 6 includes a heating cylinder 61 rotatably installed in the heat preservation box 2, a group of thread slots 65 are arranged in an annular array on the heating cylinder 61, a blowing groove 62 is arranged in the heat preservation box 2, a gap exists between the heating cylinder 61 and the heat preservation box 2, the gap is communicated with the blowing groove 62, the blowing groove 62 is communicated with the outside, and a group of fins 63 and electric heating wires 64 are arranged in an annular array on the outer periphery of the heating cylinder 61.

[0077] The fins 63 are inclined, and each group of electric heating wires 64 covers the outside of the thread slot 65

[0078] The above scheme is adopted: the fan sends air into the gap between the heat preservation box 2 and the heating cylinder 61 through the blowing groove 62, but since the fins 63 are inclined, the air can push the heating cylinder 61 to rotate through the fins 63, and finally is discharged through the thread slot 65, and the electric heating wires 64 are arranged outside the thread slot 65, so that the heat efficiency discharged through the thread slot 65 can be further improved;

[0079] The thread design of the thread slot 65 can avoid the "dead zone" that may be formed by the air flow collision of the axis part, reduce the wind speed and heat exchange efficiency, further enhance the air flow coverage of the central area, rotate the air supply, reduce the drying dead angle, and compensate for the problem of local air flow shortage, avoid overheating of the shoe 7 on one side, thereby accelerating the drying work and improving the drying quality.

[0080] The working principle and use process of the present application are as follows:

[0081] When the infrared detection system 11 detects that the shoe 7 is conveyed to the designated station by the conveying mechanism 1, the heat preservation assembly 3 closes the two ends of the heat preservation box 2, and the limiting assembly 4 fixes the shoe 7;

[0082] The fan sends air into the gap between the heat preservation box 2 and the heating cylinder 61 through the air supply groove 62, but the fins 63 are in an inclined state, so the air can push the heating cylinder 61 to rotate through the fins 63, and finally is discharged through the threaded gap 65, and the electric heating wire 64 is arranged outside the threaded gap 65, so that the heat efficiency of the air discharged through the threaded gap 65 can be further improved;

[0083] The hydraulic rod three 52 is then extended, and the positioning cylinder 56 abuts against the insole of the shoe 7, during which, due to the elastic force of the elastic member one 54, the positioning cylinder 56 is preferentially retracted into the storage cylinder 55, and the steel cable 57 is gradually loosened, and the steel ball and part of the rubber sleeve 58 are pressed into the inside of the shoe 7, thereby supporting the shoe 7;

[0084] During the process that the positioning cylinder 56 enters the storage cylinder 55, the sliding plate 561 is lowered at the same time, and since the steel ball is gradually laid in the inside of the shoe 7 and is wrapped by the rubber sleeve 58, the end of the spring expansion plate 562 is limited by the steel ball, and then the spring expansion plate 562 is folded and located above the steel ball, and finally the storage cylinder 55 pushes the pressing plate 563 to descend through the push plate 551, so as to clamp the tongue part of the shoe 7 together with the spring expansion plate 562, and further limit the position of the steel ball.

[0085] It is to be noted that the relative terms such as first and second and the like are used herein solely to distinguish one entity or action from another, without necessarily requiring or implying any such actual relationship or order between such entities or actions.
