Description

Technical Field

[0001] This utility model relates to the field of shoemaking technology, specifically to a tray clamp for placing shoe soles. Background Technology

[0002] The sole is an important component of a shoe. To enhance its aesthetics, the outer surface of the sole is often painted, resulting in different colors that are popular among young people. To improve painting efficiency, uniformity, and color variety, automated painting systems for soles have emerged in the prior art. For example, invention patent CN119056638A provides an automated painting system and its application in sole painting. To ensure the smooth transport and automatic painting of soles, a corresponding pallet clamp is needed to stably hold the soles during transport and automatic painting. Currently, existing single pallet clamps can only stably hold one sole, which is not conducive to improving the overall production efficiency of the production line. Therefore, how to achieve stable holding of multiple soles simultaneously by a single pallet clamp is the technical problem to be solved by this application. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tray clamp for placing shoe soles that can stably clamp multiple shoe soles simultaneously so that the outer circumference of multiple shoe soles can be painted together, which is conducive to further improving the overall production efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A tray clamp for placing shoe soles includes a tray, a placement plate, a pressure plate, a pressure rod, and an elastic pull rod assembly. The upper surface of the placement plate is used to place shoe soles. There are multiple placement plates located above the tray. The multiple placement plates are arranged horizontally and are arranged in parallel intervals from top to bottom and are fixedly installed on the tray by a fixing assembly. There are multiple pressure plates, which are arranged vertically and vertically corresponding to the multiple placement plates. The multiple pressure plates are all set on the elastic pull rod assembly. The elastic pull rod assembly is set on the tray and is used to apply a downward elastic force synchronously to the multiple pressure plates at all times. At least one pressure rod for pressing down the shoe sole is fixedly installed at the lower end of the pressure plate.

[0005] Furthermore, the elastic pull rod assembly includes a fixed cylinder, a pull rod, and a first compression spring. The bottom end of the fixed cylinder is mounted on a tray, and the fixed cylinder has a downward-opening cavity. The upper end of the fixed cylinder has a through hole that is adapted to the pull rod and communicates with the cavity. The pull rod is sleeved in the cavity, and its upper end extends upward through the through hole and is fixedly connected to one end of the pressure plate. The first compression spring is sleeved on the pull rod and located in the cavity. The upper end of the first compression spring abuts against the top surface of the cavity of the fixed cylinder, and the lower end of the first compression spring abuts against an annular protrusion. The annular protrusion is adapted to the cavity and fixedly located at the bottom end of the pull rod. A guide mechanism is provided between the pull rod and the fixed cylinder.

[0006] Furthermore, the guiding mechanism includes a matching strip guide groove and a guide block. The strip guide groove is arranged vertically and is located on the fixed cylinder, extending through its lower end and outer circumference. The guide block is fixedly mounted on the pull rod and is engaged in the strip guide groove with the two slidingly fitted together.

[0007] Furthermore, a locking plate is fixedly provided at the bottom of the fixed cylinder, and the locking plate is locked and fixed to the tray.

[0008] Furthermore, the pressure plate is bent and has a groove formed on one side below.

[0009] Furthermore, the fixing components include a fixing rod, a fixing plate, and a support plate. There is at least one support plate. The fixing rod and the fixing plate are both fixed to the upper end of the tray. The bottommost placement plate is fixed to at least one fixing rod, and the remaining placement plates are respectively fixed to the corresponding support plates. One end of the support plate is fixed to the fixing plate.

[0010] Furthermore, a fixing plate is provided on one side of the elastic tie rod assembly, and the fixing plate is provided with a clearance opening that allows the pressure plate to pass through.

[0011] Furthermore, a cover plate is fixed at the bottom of the placement plate, and the longitudinal section of the cover plate is a figure-eight shape that is narrower at the top and wider at the bottom.

[0012] Furthermore, the number of placement plates and pressure plates is 2-3 each.

[0013] Furthermore, there are two compression bars, a fixed compression bar and an elastic compression bar, respectively.

[0014] As described above, the tray clamp for placing shoe soles provided by this utility model has the following beneficial effects: In use, with the assistance of an external lifting mechanism, the pressure plate can be pulled upwards to cause the pressure rod to rise and move away from the corresponding placement plate. At this time, shoe soles can be manually placed onto multiple placement plates. After placement, the upward pull of the external lifting mechanism on the pressure plate can be released. Then, the downward elastic force maintained by the elastic pull rod assembly on the multiple pressure plates can cause the pressure plates and pressure rods to descend together, causing the pressure rods to abut against the corresponding placement plates. The upper part of the shoe sole is stably pressed down, preventing the sole from falling off the placement plate. This allows for stable clamping of the sole during conveying and automatic painting processes. It can also stably clamp multiple soles simultaneously, enabling subsequent painting of the outer surfaces of multiple soles together, which helps to further improve overall production efficiency. After painting is completed and the sole needs to be removed, the pressure plate can be pulled upwards again with the assistance of the external lifting mechanism, causing the pressure rod to rise and move away from the sole. At this point, the sole can be easily removed from the placement plate manually. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below through specific embodiments.

[0022] like Figures 1 to 5 As shown, the present invention discloses a tray clamp for placing shoe soles, comprising a tray 1, a placement plate 2, a pressure plate 3, a pressure rod, and an elastic pull rod assembly 5. The upper surface of the placement plate 2 is used to place the shoe sole 8. There are multiple placement plates 2 located above the tray 1. The multiple placement plates 2 are arranged horizontally and are arranged in parallel intervals from top to bottom and are fixedly installed on the tray 1 by a fixing assembly. There are multiple pressure plates 3, which are arranged vertically and vertically corresponding to the multiple placement plates 2. The multiple pressure plates 3 are all provided on the elastic pull rod assembly 5. The elastic pull rod assembly 5 is provided on the tray 1 and is used to apply a downward elastic force to the multiple pressure plates 3 synchronously at all times. At least one pressure rod for pressing down the shoe sole 8 is fixedly installed at the lower end of the pressure plate 3.

[0023] In use, with the assistance of an external lifting mechanism, the pressure plate 3 can be pulled upwards to raise the pressure rod and move it away from the corresponding placement plate 2. At this time, shoe soles 8 can be manually placed onto the multiple placement plates 2. After placement, the upward pull of the pressure plate 3 by the external lifting mechanism can be released. The downward elastic force maintained by the elastic pull rod assembly 5 on the multiple pressure plates 3 will then cause the pressure plate 3 and the pressure rod to descend together, so that the pressure rod abuts against the upper end of the corresponding shoe sole 8 and stably presses down on the shoe sole 8. This prevents the sole 8 from detaching from the placement plate 2, ensuring stable clamping of the sole 8 during conveying and automatic painting. It also allows for the simultaneous and stable clamping of multiple soles 8, facilitating simultaneous painting of their outer surfaces and improving overall production efficiency. After painting, when the sole 8 needs to be removed, the pressure plate 3 can be lifted upwards with the assistance of an external lifting mechanism, causing the pressure rod to rise and move away from the sole 8. At this point, the sole 8 can be easily removed manually from the placement plate 2.

[0024] Correspondingly, the external lifting mechanism includes a vertical linear drive 91, a horizontal linear drive 92, a lifting block 93, a lifting seat 94, a positioning block 95, a lifting rod 96, and a lifting bracket 97. The lifting bracket 97 is fixedly installed. The vertical linear drive 91 is fixedly mounted on the lifting bracket 97 and is used to drive the lifting block 93 to move vertically. The lifting seat 94 is fixedly mounted on the lifting block 93. The lifting block 93 has a positioning cavity that matches the positioning block 95. The horizontal linear drive 92 is fixedly mounted on the positioning block 96. The lifting seat 94 is used to drive the positioning block 95 to move laterally and to allow the positioning block 95 to be separably embedded in the positioning cavity. The lifting rod 96 is arranged laterally and fixed on the positioning block 95 and passes through the positioning cavity. The lifting rod 96 is separably inserted into the lower end of the uppermost pressure plate 3 and pulls the pressure plate 3 upward. Preferably, the vertical linear drive member 91 is a vertical cylinder, a vertical hydraulic cylinder or a vertical electric push rod, and the horizontal linear drive member 92 is a horizontal cylinder, a horizontal hydraulic cylinder or a horizontal electric push rod.

[0025] The elastic pull rod assembly 5 includes a fixed cylinder 51, a pull rod 52, and a first compression spring 53. The bottom end of the fixed cylinder 51 is mounted on the tray 1. The fixed cylinder 51 has a downward-opening cavity 511. The upper end of the fixed cylinder 51 has a through hole that is adapted to the pull rod 52 and communicates with the cavity 511. The pull rod 52 is sleeved in the cavity 511, and its upper end extends upward through the through hole and is fixedly connected to one end of the pressure plate 3. The first compression spring 53 is sleeved on the pull rod 52 and located in the cavity 511. The upper end of the first compression spring 53 abuts against the top surface of the cavity 511 of the fixed cylinder 51, and the lower end of the first compression spring 53 abuts against an annular protrusion 521. The annular protrusion 521 is adapted to the cavity 511 and fixedly disposed at the bottom end of the pull rod 52. The pull rod 52 and the fixed cylinder 511 are connected in series. A guide mechanism 54 is provided between the placement plates 2. When it is necessary to place shoe soles 8 on multiple placement plates 2, the pressure plate 3 can be pulled upward with the assistance of an external lifting mechanism. This will cause the pull rod 52 to rise and compress the first compression spring 53. At the same time, the pressure rod will rise and move away from the corresponding placement plate 2. At this time, shoe soles 8 can be placed on multiple placement plates 2 by hand. After placement, the upward pull of the pressure plate 3 by the external lifting mechanism can be released. At this time, the downward elastic force applied by the first compression spring 53 to the pull rod 52 can drive the pull rod 52 to move downward, thereby causing the pressure plate 3 and the pressure rod to fall together. The pressure rod will then abut against the upper end of the corresponding shoe sole 8 and stably press down on the shoe sole 8. Thus, with the cooperation of the pressure rod and the placement plate 2, the shoe sole 8 can be stably clamped.

[0026] The guiding mechanism 54 includes a matching strip guide groove 541 and a guide block 542. The strip guide groove 541 is arranged vertically and is located on the fixed cylinder 51, extending through its lower end and outer circumference. The guide block 542 is fixedly mounted on the pull rod 52 and is engaged within the strip guide groove 541 with a sliding fit between them. This provides a guiding effect for the lifting and lowering of the pull rod 52, which helps to ensure the stability of the pull rod 52 during lifting and lowering. In addition, preferably, there are two strip guide grooves 541 and two guide blocks 542, which are arranged symmetrically.

[0027] A locking plate 55 is fixedly provided at the bottom end of the fixed cylinder 51. The locking plate 55 is locked and fixed to the tray 1 by screws, so as to stably install the fixed cylinder 51 on the tray 1.

[0028] The pressure plate 3 is bent and has a groove 31 formed on one side below it to facilitate the external lifting mechanism to lift the pressure plate 3 stably. When lifting, the lifting rod 96 can be inserted into the groove 31 on one side below the uppermost pressure plate 3.

[0029] The fixing assembly includes a fixing rod 61, a fixing plate 62, and a support plate 63. There is at least one support plate 63. The fixing rod 61 and the fixing plate 62 are both fixed to the upper end of the tray 1. The lowest placement plate 2 is fixed to at least one fixing rod 61, and the remaining placement plates 2 are respectively fixed to the corresponding support plates 63. One end of the support plate 63 is fixed to the fixing plate 62. This facilitates the simultaneous fixing and installation of multiple placement plates 2.

[0030] The fixing plate 62 is located on one side of the elastic tie rod assembly 5. The fixing plate 62 is provided with a clearance opening 621 that allows the pressure plate 3 to pass through, thereby avoiding interference between the fixing plate 62 and the installation of the pressure plate 3.

[0031] The bottom end of the placement plate 2 is fixed with a cover plate 7. The longitudinal section of the cover plate 7 is a V-shape that is narrow at the top and wide at the bottom. This helps to block the paint that drifts downward during the painting process.

[0032] Preferably, there are 2-3 placement plates 2 and 3 pressure plates 3, which facilitates the simultaneous placement and fixing of 2-3 shoe soles 8.

[0033] The pressure rod consists of two parts, a fixed pressure rod 41 and an elastic pressure rod 42. Correspondingly, the elastic pressure rod 42 includes an inner rod body 421, an outer rod body 422, and a second compression spring 423. The outer rod body 422 has a downward-opening movable cavity 4221. The upper end of the outer rod body 422 has a through hole that matches the inner rod body 421 and communicates with the movable cavity 4221. The upper end of the inner rod body 421 is fixedly connected to the pressure plate 3. The lower end of the inner rod body 421 passes downward through the through hole and enters the movable cavity 4221, where a movable block 424 is fixedly connected. The movable block 424 matches the movable cavity 4221. The moving cavity 4221 is provided with a second compression spring 423. The upper end of the second compression spring 423 abuts against the bottom end of the moving block 424, and the lower end of the second compression spring 423 abuts against the sealing plate 425. The sealing plate 425 is fixedly installed at the bottom opening of the outer rod body 422. Correspondingly, the bottom end of the elastic pressure rod 42 is lower than the bottom end of the fixed pressure rod 41. Since the upper surface of the shoe sole 8 is not flat, the elastic pressure rod 42 can be adaptively compressed through the cooperation of the fixed pressure rod 41 and the elastic pressure rod 42, so as to better press the shoe sole 8 from two positions, so as to better ensure the stable clamping of the shoe sole 8.

[0034] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
