Description

Technical Field

[0001] The invention relates to the technical field of transfer devices, in particular to a transfer device for a towel production process. Background Art

[0002] The first process in towel production is warping, and the second process is drawing in and weaving. The grey cloth woven in the second process needs to undergo the third dyeing process. To transport the grey cloth roll from the second process to the third process, a transfer device is required. Commonly used transfer devices are in the form of chain conveyor belts.

[0003] The chain conveyor type transfer device usually rotates the cloth roller in one direction continuously under normal conditions. However, in some cases, such as when the unloading at the rear is not timely, causing the cloth roller to pile up on the transfer device, it is necessary to suspend the continuous rotation of the chain and change to intermittent feeding and transmission of the chain by inching control to adapt to the frequency of unloading one by one at the rear, until all the accumulated cloth rollers are unloaded and the efficient continuous transmission of the transfer device under normal conditions is restored;

[0004] Most of the existing chain transfer devices lack a mechanism that can suppress or reduce the inertial impact force generated when the cloth roller suddenly stops or the inching feed transmission stops frequently during the transportation process, resulting in the chain body being the only one to pull to meet the inertial impact force and complete the braking and positioning of the cloth roller. This will cause impact damage to the chain in the long run and affect the service life of the chain. Summary of the invention

[0005] In view of this, the present invention provides a towel production process transfer device to solve the problem of lack of a mechanism that can suppress or reduce the inertial impact force generated when the cloth roller suddenly stops or the inching feed transmission stops frequently during the transportation process, resulting in the chain having to rely on the chain body to pull to meet the inertial impact force and complete the braking and positioning of the cloth roller, thereby affecting the service life of the chain.

The cross section of the track is an L-shaped structure. A chain is tensioned and installed between the two sprockets, and a circle of driving rods is fixed around the chain. The front axle is connected to the drive assembly for transmission:

[0008] The cloth roller transfer frame as a whole is composed of two inverted U-shaped vertical support frames symmetrically arranged front and back, and two arc-shaped support plates symmetrically welded between the left and right parts of the top of the two inverted U-shaped vertical support frames, wherein the bottom of the two inverted U-shaped vertical support frames are penetrated and rotatably installed with a roller, and two sets of rollers are symmetrically welded and set on the left and right ends of the roller, and the rollers are in rolling contact with the support frame; the left and right ends of the two rollers are convexly arranged, and the convex parts of the left and right ends of the two rollers correspond to the two rails for sliding cooperation; the two arc-shaped support plates are used to support and place the towel grey cloth roller;

[0009] A driving plate is rotatably connected between the middle shaft sections of the two rollers, and a waist-shaped sliding groove is penetrated through the middle position of the driving plate, and the driving rod is plugged into and matched with the waist-shaped sliding groove; a hexagonal sliding shaft is slidably pushed by a spring on the tail end part of the driving plate, and the head end of the hexagonal sliding shaft is in contact with the driving rod; the tail end of the hexagonal sliding shaft is rotatably connected with two connecting rods, and the tail ends of the two connecting rods are rotatably connected with a brake circular plate, and the two brake circular plates correspond to the rear rollers for sliding cooperation, and the two brake circular plates slide away from each other and correspond to the left and right groups of rollers.

[0010] Furthermore,

[0011] The supporting frame is in the form of a flat rectangle with semicircular structures at the front and rear ends, and the track has the same shape as the supporting frame.

[0012] Furthermore,

[0013] A positioning sleeve is welded at the tail end of the driving plate, the hexagonal sliding shaft and the positioning sleeve penetrate and slide in cooperation, and the driving plate is limited to the middle section of the two rollers.

[0014] Furthermore,

[0015] The head end of the hexagonal sliding shaft is provided with an arc-shaped notch, and the arc-shaped notch is plug-matched with the driving rod.

[0016] Furthermore,

[0017] A circle of L-shaped connecting plates is welded between the track and the supporting frame.

[0018] Furthermore,

[0019] Two vertical support plates are symmetrically welded inside the front and rear ends of the support frame, and the middle parts of the four vertical support plates corresponding to the left and right ends of the two wheel axles penetrate and rotate together.

[0020] Furthermore,

[0021] The driving assembly is fixed to the vertical support plate on the right side of the front end by screw locking.

[0022] Furthermore,

[0023] At least two frames are welded on the mounting bracket at equal intervals, and the frame as a whole is composed of a horizontal support touching the floor and two L-shaped vertical support plates symmetrically welded to the top of the horizontal support touching the floor, wherein an I-shaped connecting frame is welded between the top parts of the two L-shaped vertical support plates, and the left and right vertical support parts of the I-shaped connecting frame are welded and fixed together with the upper and lower side rods of the two supporting frames.

[0024] Furthermore,

[0026] The towel production process transfer device provided by the present invention has the following beneficial effects:

[0027] When the present invention is in use, when the transfer device stops or is used for inching start and stop feeding and transmission, when the chain stops, the cloth roller transfer frame and the towel grey cloth roller supported thereon will have a tendency to continue to move forward, generating a forward inertial impact and driving the cloth roller transfer frame to move forward. At this time, the hexagonal sliding shaft will be pushed back by the stopped driving rod to slide backward, controlling the two brake discs to automatically slide away from each other and squeeze the two groups of rollers, reducing the inertial impact force and assisting the cloth roller transfer frame in braking positioning, sharing the pushing and pulling force acting on the chain. Compared with the prior art, it can avoid simply and directly using the chain to meet and resist the braking inertial impact force from the towel grey cloth roller, which helps to reduce the impact damage to the chain and extend the service life of the chain.

[0028] In addition, the brake assembly of the present invention, which is composed of two crank slider mechanisms, can convert the inertial impact force of the towel grey cloth roller when it stops into a force to press and brake it through the power transmission of the hexagonal sliding shaft and the spring thereon. There is no need to additionally configure a device for outputting the braking force for the brake assembly. Moreover, through the power transmission of the hexagonal sliding shaft and the spring thereon, the brake assembly can utilize the inertial impact force generated when the car stops to drive automatic tightening and loosening, which saves the trouble of frequent manual tightening and loosening of the brake assembly, and also saves the need to additionally configure a device for automatically starting and stopping the tightening and loosening for the brake assembly.

[0029] In addition, when the driving rod needs to rotate and change its angle after being driven by the chain to the position of two sprockets, the waist-shaped groove can provide a margin space for the angle change and telescopic sliding of the driving rod, thereby avoiding interference between the driving plate and the driving rod and affecting the rotation and circulation transmission of the chain to the cloth roller transfer frame.
