Description

Technical Field

[0001] This invention relates to the field of hose processing technology, and in particular to a hub-type mandrel holder with a mold release agent recovery device. Background Technology

[0002] Rubber hoses are used in many fields of daily life and production, such as the petroleum, metallurgical, and chemical industries. The processing of rubber hoses requires core removal and imprinting, which involves adding a core remover to the vulcanized hose to remove the core rod, and then imprinting the specifications and manufacturer information on the outside of the hose. For example, Chinese Patent 201310450718.6 discloses a method for processing rubber hoses, involving the rubber processing field, including six process steps: extruding the rubber layer, braiding the load-bearing skeleton, hose wrapping, cutting and shaping, vulcanization, and core removal and imprinting. Raw rubber is fed into a cold-feed extruder, extruding the hose blank and molding it onto a polyimide soft core rod. The produced hose is high-temperature resistant, fire-resistant, has high productivity, low energy and water consumption, and requires a small production area for equipment installation. The cut hose is placed in a microwave vulcanization device, rapidly heated to the vulcanization temperature, and then subjected to a second vulcanization in a hot air bath, shortening the rubber vulcanization time, improving heating uniformity, and increasing the automation level of product processing.

[0003] In existing hose processing technology, the mandrel in the mandrel holder is fixed to the base plate. When inserting or removing the hose, the base plate needs to be lifted and placed on a designated workbench to prevent the release agent on the mandrel holder from leaking out. This process is time-consuming. Furthermore, the limited space on the workbench and the limited number of base plates that can be placed result in low hose insertion and removal efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a hub-type mandrel holder with a mold release agent recovery device to solve the problems of inconvenient insertion and removal of rubber tubes and low efficiency in existing mandrel holders.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hub-type mandrel holder with a mold release agent recovery device, comprising:

[0006] A release agent recovery tray is provided with a support base. A locking plate is provided on one side of the support base. At least one floating plate mounting groove is provided on the locking plate. The floating plate is placed in the floating plate mounting groove and is elastically connected in the floating plate mounting groove. Ventilation holes are provided on the bottom surface of the floating plate mounting groove.

[0007] The mandrel holder body includes a rotating shaft, mandrel groups, and a turntable. Several mandrel groups are arranged circumferentially on the rotating shaft. Each mandrel group includes several mandrels arranged along the axis of the rotating shaft. The turntable is fixedly installed on the rotating shaft. A locking block with a shape matching the mounting groove of the floating plate is provided on the turntable. The locking block is elastically connected to the turntable.

[0008] As a further description of the above technical solution:

[0009] The locking plate has four floating plate mounting slots arranged circumferentially along the rotating shaft, and the turntable has four locking blocks.

[0010] As a further description of the above technical solution:

[0011] A handle is provided on the turntable.

[0012] As a further description of the above technical solution:

[0013] The turntable has four handles arranged circumferentially.

[0014] As a further description of the above technical solution:

[0015] The handle is detachably mounted on the turntable.

[0016] As a further description of the above technical solution:

[0017] The handle is threaded onto the turntable.

[0018] As a further description of the above technical solution:

[0019] The turntable has four through holes arranged circumferentially along the axis of rotation. The through holes and locking blocks are arranged at intervals. The locking plate is equipped with sensors whose positions correspond to the through holes.

[0020] As a further description of the above technical solution:

[0021] The bottom of the mold release agent recovery tray is equipped with rollers.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, when inserting or removing hoses on the hub-type mandrel holder, the release agent recovery tray below the mandrel holder body can effectively collect the release agent, preventing its loss and eliminating the need for frequent handling of the mandrel holder. The mandrel holder body rotates on the support base via a pivot, allowing for angle adjustment and facilitating hose insertion and removal. The mandrel holder body integrates a large number of mandrels, enabling simultaneous insertion and removal of hoses from both sides, effectively improving hose insertion and removal efficiency.

[0024] 2. In this invention, on the locking plate of the support base, an air pipe is set at the vent hole to connect to the air source in the floating plate mounting groove. When the air source introduces gas into the floating plate mounting groove through the air pipe, the floating plate can be pushed outward, the locking block retracts and disengages from the floating plate mounting groove, and then the turntable is rotated to adjust the angle of the mandrel frame body, which facilitates the insertion and removal of the rubber tube on the mandrel at different positions.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0034] Example 1

[0035] Please see Figure 1-4 The present invention provides a technical solution: a hub-type mandrel holder with a mold release agent recovery device, comprising:

[0036] The mold release agent recovery tray 1 is provided with a support base 11. A locking plate 12 is provided on one side of the support base 11. At least one floating plate mounting groove is provided on the locking plate 12. The floating plate 13 is provided in the floating plate mounting groove and is elastically connected to the floating plate mounting groove. A vent hole 14 is provided on the bottom surface of the floating plate mounting groove.

[0037] The mandrel holder body 2 includes a rotating shaft 21, mandrel groups and a turntable 23. Several mandrel groups are arranged circumferentially on the rotating shaft 21. Each mandrel group includes several mandrels 22 arranged along the axis of the rotating shaft 21. The turntable 23 is fixedly installed on the rotating shaft 21. The turntable 23 is provided with a locking block 231 whose shape matches the mounting groove of the floating plate. The locking block 231 is elastically connected to the turntable 23.

[0038] The locking disc 12 is provided with four floating plate mounting slots arranged circumferentially along the rotating shaft 21, and the turntable 23 is provided with four locking blocks 231. When a single person inserts or removes the hose, the turntable can be rotated four times, each time by 90 degrees, to facilitate operation of the mandrel 22 on the mandrel assembly; when two workers insert or remove the hose from both sides, they can rotate it 180 degrees at a time.

[0039] A handle 232 is provided on the turntable 23 to facilitate the rotation of the turntable 23.

[0040] The turntable 23 is equipped with four circumferentially arranged handles, which further facilitates the rotation of the turntable 23 and controls the rotation angle.

[0041] The handle 232 is detachably mounted on the turntable 23. Specifically, the handle 232 is threaded onto the turntable 23 for easy removal and replacement.

[0042] The turntable 23 has four through holes 233 arranged circumferentially along the rotating shaft 21. The through holes 233 and locking blocks 231 are spaced apart. The locking plate 12 is equipped with sensors 121 whose positions correspond to the through holes 233. After the floating plate 13 is pushed outward, the sensor 121 identifies the through holes 233 to determine the rotation angle of the turntable 23. When a single person inserts or removes the hose and the turntable 23 needs to be rotated 90 degrees each time, after the sensor 121 identifies one through hole 233 has rotated, the air source is depressurized, causing the floating plate 13 to retract, making it easier for the locking block 231 to insert into the floating plate mounting slot and lock the turntable. When two people operate and the turntable 23 needs to be rotated 180 degrees each time, after the sensor 121 identifies two through holes 233 have rotated, the air source is depressurized, causing the floating plate 13 to retract.

[0043] The bottom of the mold release agent recovery tray 1 is equipped with rollers 15 for easy movement of the hub-type mandrel holder.

[0044] Working Principle: When inserting or removing hoses on the hub-type mandrel holder, the release agent recovery tray 1 below the mandrel holder body 2 can effectively collect the release agent, preventing its loss and eliminating the need for frequent mandrel holder handling. The mandrel holder body 2 rotates on the support base 11 via a pivot 21, adjusting its angle for easy hose insertion and removal. The mandrel holder body 2 integrates numerous mandrels 22, allowing simultaneous insertion and removal of hoses from both sides without requiring placement on a designated workbench, thus significantly improving hose insertion and removal efficiency. On the locking disc 12 of the support base 11, an air source is connected to the floating plate mounting slot via an air pipe at the vent 14. When air is introduced into the floating plate mounting slot through the air pipe, the floating plate 13 can be pushed outwards, and the locking block 231 retracts from the floating plate mounting slot. Then, rotating the turntable 23 adjusts the angle of the mandrel holder body 2, facilitating hose insertion and removal from different positions on the mandrels 22.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
