Description

Technical Field

[0001] This utility model relates to the field of shoe upper fabric shaping technology, specifically to a material handling auxiliary device for a water chiller. Background Technology

[0002] In the shoe manufacturing process, in order to ensure that the shoe upper fabric is quickly and stably formed, improve the bonding strength and prevent heat damage, the shoe upper fabric needs to be flattened at a temperature below 10°C (commonly known as "cooling and setting").

[0003] In the existing technology, after the shoe upper fabric is placed on a water-cooled low-temperature platform, it is stamped and shaped at low temperature by a vertically moving pressure plate. This stamping and shaping process takes tens of seconds to several minutes. After the process is completed, the operator needs to remove the shaped fabric from the low-temperature platform.

[0004] The temperature of the cryogenic platform is maintained between 4℃ and 10℃. When operators pick up and put down shoe upper fabric, their hands will inevitably come into contact with the surface of the cryogenic platform. Although this temperature range is not enough to cause the hand tissue to freeze, the total contact time between the hands and the cryogenic platform is long under repeated operation in a workday. This will cause vasoconstriction and tissue ischemia and hypoxia, which will eventually lead to serious non-freezing cold injury. Such injury has the potential to cause serious consequences such as pain, numbness, swelling, nerve damage, skin ulceration and even tissue necrosis.

[0005] At the same time, because the upper fabric of the shoes is relatively thin, if the operator wears heat-insulating gloves to perform the picking and placing operations, the thickness and flexibility of the gloves will limit the effectiveness of the picking and placing actions. Utility Model Content

[0006] The purpose of this utility model is to provide a material handling auxiliary device for a water chiller, so as to solve the problems mentioned in the background art above:

[0007] When operators pick up and put down shoe upper fabric, their hands will inevitably come into contact with the surface of the low-temperature platform, and the low temperature will cause damage to their hands.

[0008] To address the above problems, the present invention aims to provide a material handling auxiliary device for a water chiller, comprising an assembly frame. A serpentine metal tube is horizontally fixed inside the assembly frame, with both ends of the serpentine metal tube penetrating one side of the assembly frame and fixedly connected to pipe joints. Two stamping stations are provided on the upper side of the serpentine metal tube. Each stamping station includes a metal plate fixedly installed on the upper side wall of the assembly frame. The lower side wall of the metal plate contacts the circumferential outer wall of the serpentine metal tube. A material handling frame is slidably disposed on the upper side wall of the metal plate, and the upper side wall of the metal plate has an opening adapted to the shape of the material handling frame. The receiving groove has an outer plate horizontally fixedly installed on the outer wall of the assembly frame at a position corresponding to the feeding frame. The upper side wall of the outer plate and the upper side wall of the metal plate form a continuous plane. A displacement mechanism is provided on the metal plate. The displacement mechanism is used to drive the feeding frame to move horizontally between the outer plate and the upper side wall of the metal plate, and to drive the feeding frame to move vertically on the metal plate. After the displacement mechanism drives the feeding frame to move horizontally from the upper side wall of the outer plate to directly above the receiving groove, the displacement mechanism drives the feeding frame to move downward to the inside of the receiving groove until the upper side wall of the feeding frame and the upper side wall of the metal plate are on the same plane.

[0009] As a further improvement to this technical solution, two extension rods are horizontally fixedly connected to the side of the feeding frame away from the outer plate, and the other ends of the two extension rods are vertically fixedly connected to the same vertical plate.

[0010] As a further improvement to this technical solution, the displacement mechanism includes a lead screw slide fixedly installed on the side wall of the metal plate. A cantilever is horizontally fixedly installed on the side wall of the lead screw slide. Two parallel connecting rods are hinged between the vertical plate and the cantilever on the side near the outer plate. The two connecting rods are inclined and distributed vertically.

[0011] As a further improvement to this technical solution, a U-shaped groove adapted to the shape of the extension rod and the vertical plate is provided on the side wall of the metal plate, and the U-shaped groove is connected to the receiving groove.

[0012] As a further improvement to this technical solution, the displacement mechanism also includes a baffle that is vertically fixed to the side wall of the metal plate. When the slide of the lead screw slide table drives the vertical plate to contact the baffle through the cantilever and connecting rod, the extension rod and the vertical plate are located directly above the U-shaped groove, and the feeding frame is located directly above the receiving groove.

[0013] As a further improvement to this technical solution, the side of the receiving groove and the U-shaped groove near the outer plate is set as a transition slope, and the two sides of the transition slope extend to the bottom surface of the receiving groove and the U-shaped groove and the upper side wall of the metal plate, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The material handling auxiliary device of this water chiller, when the screw slide drives the vertical plate to contact the baffle, the extension rod and the vertical plate are directly above the U-shaped groove, the material handling frame is directly above the receiving groove, and the shoe upper fabric is directly below the pressure plate, completing the feeding of the shoe upper fabric. Then the screw slide drives the slide to move towards the baffle, the baffle blocks the vertical plate, causing it to move vertically downwards. The extension rod drives the material handling frame to descend synchronously into the receiving groove, avoiding obstruction of the pressure plate for subsequent stamping and shaping of the shoe upper fabric. After the pressure plate completes the stamping and shaping and resets, the screw slide drives the slide away from the baffle, causing the vertical plate and the material handling frame to move up along the transition slope to the upper side wall of the metal plate. The shoe upper fabric re-enters the material handling frame. Then the screw slide continues to drive the material handling frame to move towards the outer plate, moving it and the inner shoe upper fabric above the outer plate to complete the unloading. During the entire material handling process, the operator's hands do not need to touch the low-temperature metal plate, effectively avoiding damage to the hands caused by low temperature.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a material handling auxiliary device for a water chiller, including an assembly frame 1. A serpentine metal tube 3 is horizontally fixed inside the assembly frame 1. Several support rods are horizontally arrayed and fixed inside the assembly frame 1. The upper sidewall of the support rods contacts the bottom of the serpentine metal tube 3. The support rods are used to support the serpentine metal tube 3 so that it maintains a stable horizontal state inside the assembly frame 1.

[0029] Both ends of the serpentine metal tube 3 pass through one side of the assembly frame 1 and are fixedly connected with pipe joints 31. The two pipe joints 31 are respectively connected to the inlet and outlet of an external industrial chiller through pipes. The industrial chiller is a mature product that can be purchased on the market. Its specific structure and working principle will not be described in detail here. The industrial chiller continuously injects cold water of 4℃–10℃ into the serpentine metal tube 3 and receives the cold water flowing out, so that the cold water circulates inside the serpentine metal tube 3. During this process, the cold water exchanges heat with the tube wall of the serpentine metal tube 3, so that the tube wall temperature of the serpentine metal tube 3 drops to 4℃–10℃.

[0030] Two stamping stations 2 are provided on the upper side of the serpentine metal tube 3. The stamping stations 2 are used to place the shoe upper fabric. (Refer to...) Figure 3 The stamping station 2 includes a metal plate 21 fixedly installed on the upper side wall of the assembly frame 1. The lower side wall of the metal plate 21 is in contact with the outer circumferential wall of the serpentine metal tube 3. Through heat exchange with the tube wall of the serpentine metal tube 3, the metal plate 21 is cooled to 4–10°C. After the shoe upper fabric is placed on the upper side wall of the metal plate 21, the shoe upper fabric is cooled down synchronously through heat exchange with the cooled metal plate 21, thereby realizing the stamping and shaping of the shoe upper fabric in a low temperature environment.

[0031] A stamping mechanism is provided directly above the metal plate 21. The stamping mechanism includes a cylinder that is fixedly installed on the upper side wall of the assembly frame 1 by a bracket. A pressure plate is horizontally fixed at the lower end of the piston rod of the cylinder. When the piston rod of the cylinder extends and drives the pressure plate to move vertically downward, the pressure plate presses the shoe upper fabric placed on the upper side wall of the metal plate 21 downward, thereby stamping and shaping the shoe upper fabric.

[0032] To prevent operators from touching the low-temperature metal plate 21 during the handling of shoe upper fabric, a feeding frame 25 is slidably installed on the upper side wall of the metal plate 21. The width of the internal space of the feeding frame 25 is adapted to the width of the shoe upper fabric. A receiving groove 22 adapted to the shape of the feeding frame 25 is opened on the upper side wall of the metal plate 21. The position of the receiving groove 22 corresponds to the position of the pressure plate. An outer plate 11 is horizontally fixedly installed on the outer side wall of the assembly frame 1 at the position corresponding to the feeding frame 25. The outer plate 11 does not exchange heat with the serpentine metal tube 3 and its temperature is maintained at room temperature. The upper side wall of the outer plate 11 and the upper side wall of the metal plate 21 form a continuous plane. A displacement mechanism is provided on the metal plate 21. The displacement mechanism is used to drive the feeding frame 25 to move horizontally between the outer plate 11 and the upper side wall of the metal plate 21, and to drive the feeding frame 25 to move vertically on the metal plate 21.

[0033] In the initial state, the feeding frame 25 is located directly above the outer plate 11. The operator places the shoe upper fabric on the upper side wall of the outer plate 11 and places the shoe upper fabric inside the feeding frame 25. Then, the displacement mechanism drives the feeding frame 25 to move horizontally from the upper side wall of the outer plate 11 to directly above the receiving groove 22. At this time, the feeding frame 25 drives the shoe upper fabric to move synchronously to the upper of the receiving groove 22, so that the shoe upper fabric is accurately positioned directly below the pressure plate, completing the feeding of the shoe upper fabric. Then, the displacement mechanism drives the feeding frame 25 to move downward to the inside of the receiving groove 22 until the upper side wall of the feeding frame 25 is on the same plane as the upper side wall of the metal plate 21, so as to avoid the feeding frame 25 obstructing the pressure plate from pressing the shoe upper fabric. Then, the operator can control the cylinder to drive the pressure plate to press and shape the shoe upper fabric.

[0034] After the shoe upper fabric is stamped and shaped, the cylinder drives the pressure plate to move up and reset. The displacement mechanism then drives the feeding frame 25 to move out of the receiving groove 22, so that the feeding frame 25 covers the shoe upper fabric again. Then the displacement mechanism drives the feeding frame 25 (along with the shoe upper fabric inside) to move horizontally above the outer plate 11 to complete the feeding of the shoe upper fabric. During the entire feeding process, the operator's hands do not need to come into contact with the low-temperature metal plate 21, effectively avoiding damage to the hands caused by low temperature.

[0035] Two extension rods 251 are horizontally fixedly connected to the side of the material feeding frame 25 away from the outer plate 11, and the other end of the two extension rods 251 is vertically fixedly connected to the same vertical plate 26.

[0036] The following details the structure of the displacement mechanism, referring to... Figures 4-6The displacement mechanism includes a lead screw slide 23 fixedly installed on the upper side wall of the metal plate 21. The lead screw slide 23 is a commercially available mature product, and its structure and working principle will not be described in detail here. The slide of the lead screw slide 23 can move horizontally. A cantilever 24 is fixedly installed horizontally on the upper side wall of the lead screw slide 23. Two parallel connecting rods 27 are hinged between the vertical plate 26 and the cantilever 24 on the side near the outer plate 11. The two connecting rods 27 are inclined and distributed vertically. Thus, the two connecting rods 27, the cantilever 24 and the vertical plate 26 together constitute a parallel four-bar linkage. A U-shaped groove 221 adapted to the shape of the extension rod 251 and the vertical plate 26 is opened on the upper side wall of the metal plate 21. The U-shaped groove 221 is connected to the receiving groove 22. The displacement mechanism also includes a baffle 28 fixedly installed vertically on the upper side wall of the metal plate 21.

[0037] When feeding the shoe upper fabric, the lead screw slide 23 drives its slide to move. The slide moves the vertical plate 26 away from the outer plate 11 through the cantilever 24 and the connecting rod 27. The vertical plate 26 drives the feeding frame 25 (together with the shoe upper fabric inside) to move synchronously through the extension rod 251. When the vertical plate 26 contacts the baffle 28, the extension rod 251 and the vertical plate 26 are directly above the U-shaped groove 221, the feeding frame 25 is directly above the receiving groove 22, and the shoe upper fabric is directly below the pressure plate.

[0038] Subsequently, the lead screw slide 23 drives its slide (driving the cantilever 24) to move towards the baffle 28. Because the baffle 28 obstructs the movement of the vertical plate 26, the distance between the vertical plate 26 and the cantilever 24 decreases. During this process, the two connecting rods 27 rotate synchronously. Since the two connecting rods 27, the cantilever 24, and the vertical plate 26 form a parallel four-bar linkage, when the cantilever 24 continues to move horizontally towards the baffle 28 while the vertical plate 26 is blocked from horizontal movement by the baffle 28, the geometric constraints of this structure force the vertical plate 26 to move only downwards in the vertical direction. Therefore, the vertical plate 26 is driven to move vertically downward. The downward-moving vertical plate 26 drives the feeding frame 25 to descend synchronously through the extension rod 251, so that the feeding frame 25 enters the receiving groove 22. At the same time, the lower end of the vertical plate 26 and the two extension rods 251 also move into the U-shaped groove 221. By storing the extension rods 251 and the feeding frame 25 in the receiving groove 22 and the U-shaped groove 221 respectively, when the pressure plate moves down to press and shape the shoe upper fabric, the extension rods 251 and the feeding frame 25 do not hinder the pressure plate from pressing the shoe upper fabric, ensuring the shaping of the shoe upper fabric.

[0039] The receiving groove 22 and the U-shaped groove 221 are both set as transition slopes on the side near the outer plate 11. The two sides of the transition slopes extend to the bottom surface of the receiving groove 22 and the U-shaped groove 221 and the upper side wall of the metal plate 21, respectively.

[0040] After the pressure plate completes the stamping and shaping of the shoe upper fabric and moves upward and resets, the screw slide 23 drives the slide to move away from the baffle 28 (backward). The slide drives the vertical plate 26 to move synchronously through the cantilever 24 and the connecting rod 27. The vertical plate 26 then drives the feeding frame 25 to move towards the outer plate 11 through the connecting rod 27. During this movement, the vertical plate 26 and the feeding frame 25 move out from the inside of the receiving groove 22 and the U-shaped groove 221 along the transition slope to the upper side wall of the metal plate 21, so that the shoe upper fabric re-enters the feeding frame 25. Then the screw slide 23 continues to drive the feeding frame 25 closer to the outer plate 11, moving the feeding frame 25 and the shoe upper fabric inside it above the outer plate 11, completing the feeding of the shoe upper fabric.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
