Description

Technical Field

[0001] This utility model belongs to the technical field of rubber product manufacturing equipment, and specifically relates to a rubber sheet production transfer trolley. Background Technology

[0002] In the rubber sheet production process, the rubber sheets need to be transferred and transported multiple times between vulcanization molding and subsequent cutting, inspection, and packaging. The efficiency of the transfer links and the quality of the rubber sheets during transport directly affect the continuity of the entire production process and the quality of the final product. Currently, the most common methods for transferring rubber sheets in the industry rely on manual handling or ordinary flatbed carts. Manual handling is not only labor-intensive and inefficient, but also prone to causing creases and damage to the rubber sheets due to improper handling during transport. Furthermore, human contact can contaminate the surface of the rubber sheets. While ordinary flatbed carts can reduce some labor intensity, they have several inherent drawbacks. 1. Lack of effective dustproof structure, the rubber sheet easily absorbs dust and impurities from the production environment during the transfer process, affecting the cleanliness of the product surface; 2. The height of the trolley's load-bearing surface is fixed and cannot be adjusted according to the operating height of different processes, which causes operators to frequently bend over or raise their arms when picking up and placing rubber sheets, increasing operator fatigue. 3. Poor ventilation when rubber sheets are stacked, especially for newly formed, warm rubber sheets, which are prone to local aging or dampness due to uneven heat dissipation; 4. The friction between the rubber sheet and the bearing surface is large, and when a single rubber sheet is picked up or put down, it is easy to cause other stacked rubber sheets to shift, affecting the stability of transportation. Summary of the Invention

[0003] Given the technical problems existing in the background technology, there is an urgent need for a rubber sheet transfer device that can take into account transfer efficiency, product protection and ease of operation, so as to solve the problems of poor dust protection, non-adjustable height, poor ventilation and inconvenience of picking and placing in the existing transfer method.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rubber sheet production transfer trolley includes a base plate, a placement plate, and a supporting base frame. The base plate is equipped with casters at the four corners of its bottom. Side plates are vertically arranged on both sides of the upper surface of the base plate. The supporting base frame is slidably inserted between the side plates. The placement plate is slidably inserted into the supporting base frame. The rubber sheet is placed on the placement plate during the transfer process. A top plate is provided on the top of the side plates. A dustproof cloth is provided on the lower surface of the top plate.

[0005] In a preferred embodiment, the inner side of the side plate is provided with first sliding grooves at equal intervals, and the two sides of the supporting base frame slide in cooperation with the first sliding grooves; the side of the supporting base frame and the side plate are respectively provided with limit screw holes, and the limit bolts are threadedly connected to the limit screw holes to lock and fix the position of the supporting base frame; a transmission roller is provided inside the supporting base frame.

[0006] In a preferred embodiment, a second sliding groove is provided on the inner side of the supporting base frame, the two sides of the placement plate slide in cooperation with the second sliding groove, and the bottom surface of the placement plate rolls in contact with the conveyor roller; ventilation holes are evenly provided on the placement plate.

[0007] In a preferred embodiment, a locking hole is provided at the end of the second slide groove, and a locking pin is inserted into the locking hole to lock and fix the placement plate inside the second slide groove.

[0008] In the preferred embodiment, a fan is installed on the upper surface of the base plate.

[0009] In the preferred embodiment, handrails are provided on the outer side of the side panel.

[0010] In the preferred embodiment, the upper surface of the top plate is a sloping structure, and the lower surface of the top plate is provided with an annular track groove.

[0011] In a preferred embodiment, a slider is engaged within the annular track groove, and the slider slides along the annular track groove for a limited position; an operating rod is vertically connected to the lower end face of the slider, and a dustproof cloth is connected between the walls of the operating rod.

[0012] A rubber sheet production transfer trolley can achieve the following beneficial effects: 1. This utility model, through the linkage structure of the dustproof cloth set on the lower end face of the top plate, the annular track groove, the slider and the operating rod, can realize the flexible opening and closing of the dustproof cloth. When picking up and putting down the rubber sheet, the operating rod drives the slider to slide along the annular track groove to open the dustproof cloth. During the transfer process, the dustproof cloth is closed, which can effectively prevent dust and impurities in the production environment from adsorbing onto the surface of the rubber sheet. This solves the problem of poor dustproof effect of existing transfer equipment and ensures the cleanliness of the rubber sheet surface and product quality. 2. The first sliding groove of the support base frame and the inner side of the side plate slides together, and the locking and fixing structure of the limit bolt and the limit screw hole can flexibly adjust the load-bearing height of the support base frame and the placement plate according to the operating height of different processes such as vulcanization, cutting and inspection. This avoids operators from frequently bending over or lifting their arms to pick up and put down rubber sheets, significantly reducing labor fatigue and improving the convenience of operation and transfer efficiency. 3. The evenly spaced ventilation holes on the placement plate and the fan on the upper surface of the bottom plate form an efficient ventilation system. Combined with the bottom gap formed by the support of the transfer rollers in the support frame, it can accelerate air circulation. Especially for newly formed warm rubber sheets, it can quickly remove heat and avoid local aging or dampness caused by poor ventilation during stacking, effectively ensuring the quality stability of the rubber sheets during the transfer process. 4. The conveyor rollers inside the support frame roll in contact with the bottom surface of the placement plate, which greatly reduces the friction when the placement plate slides, making it easier to pull the placement plate along the second slide to pick up and put down the rubber sheet. It also prevents other stacked rubber sheets from shifting when picking up and putting down a single rubber sheet. At the same time, the locking hole and locking pin at the end of the second slide can lock the position of the placement plate during the transfer process to prevent it from sliding and causing creases or damage to the rubber sheet, thus balancing the convenience of picking up and putting down the rubber sheet with the stability of the transfer.
