Embodiment 1

[0032] Example 1: Easy joint PVC core polyvinyl chloride conveyor belt

[0033] see Figure 1-2 The shown easy-joint PVC core polyvinyl chloride conveyor belt includes a ring-type PVC core skeleton 1 and a polyvinyl chloride resin coating layer (covering layer) 2 coated on the upper surface of the ring-type PVC core skeleton.

[0034] The ring-type PVC core skeleton is composed of PVC straight cores 3 and PVC winding cores 4; there are more than three PVC straight cores arranged in parallel and at intervals. Between two adjacent PVC straight cores, there is a PVC winding core that spirally bypasses adjacent two PVC straight cores; two PVC winding cores wound on the same PVC straight core The cores are spaced apart in the axial direction. see Figure 4 , the helical directions of two PVC winding cores wound on the same PVC straight strip core are opposite. see Figure 5Looking at a PVC winding core from the axial direction of the PVC straight strip core, the PVC winding co...

Embodiment 2

[0036] Embodiment 2: the preparation of easy joint PVC core polyvinyl chloride conveyor belt

[0037] The preparation process of this easy-joint PVC core polyvinyl chloride conveyor belt, see the flow chart Figure 6 As shown, it mainly includes the following steps:

[0038] (1) Preparation of ring-type PVC core skeleton

[0039] Ring buckle PVC core skeleton structure such as Figure 4-5 As shown, there are PVC winding core a, PVC winding core b (the PVC winding core is divided into a and b for the convenience of expression, the diameter of the PVC winding core is about 0.8mm) and PVC straight core 3 (the diameter is about 1mm) composition. Among them, PVC winding core a is coiled clockwise on two adjacent PVC straight cores from bottom to top to form a chain, and PVC winding core b is counterclockwise on two adjacent PVC straight cores from bottom to top. Winding into a chain shape, PVC winding core a and PVC winding core b are interspersed at intervals of each circle, P...

Embodiment 3

[0046] Embodiment 3: the joint method of easy joint PVC core polyvinyl chloride conveyor belt

[0047] The joint process is greatly simplified by using the ring-type PVC core skeleton instead of the conventional fabric core skeleton. The specific joint method is described as follows:

[0048] (1) End cutting

[0049] Determine the length and width of the conveyor belt to be used according to the requirements of the actual assembly line equipment, and cut it accurately, such as Figure 7 , 8 As shown, the two ends 5 and 6 that need to be butted in the length direction of the conveyor belt are cut along the outer edge of the winding core, and the ends of the winding core are kept intact.

[0050] Pull out the PVC straight strip core on the cut end to get the conveyor belt end without PVC straight strip core fixed, such as Figure 9 , 10 shown.

[0051] (2) Soften stitching

[0052] Such as Figure 11 , 12 As shown, heat the two ends of the conveyor belt with the PVC...

Abstract

The invention provides an easy-joint PVC (polyvinyl chloride)-core polyvinyl chloride conveying belt which has the advantages of simplicity and convenience in joint operation during jointing of the conveying belt, high joint strength retention rate and long service life. The easy-joint PVC-core polyvinyl chloride conveying belt comprises a buckle type PVC-core framework and a polyvinyl chloride resin coating coated on the upper surface of the buckle type PVC-core framework, the buckle type PVC-core framework consists of more than three PVC strip cores and PVC winding cores, the PVC strip cores are arranged at intervals parallelly, each PVC winding core which is helical and sequentially bypasses two adjacent PVC strip cores is arranged between the two adjacent PVC strip cores, and each two PVC winding cores wound on the same PVC strip core are spaced in the axial direction of the PVC strip core.

Description

technical field [0001] The technology relates to a polyvinyl chloride conveyor belt, in particular to an easy-joint PVC core polyvinyl chloride conveyor belt and a preparation method thereof. Background technique [0002] Since 2000, the development of the domestic new material light conveyor belt industry has become increasingly mature. As the most widely used product in the light conveyor belt industry, PVC conveyor belt has the advantages of light weight, friction resistance, water resistance, flame retardancy, acid and alkali resistance, and non-toxicity, and can be safely used in food processing and other industries. In the actual application process, the joint methods of the conventional fabric core PVC light conveyor belt mainly include mechanical connection method and thermal bonding method. The mechanical connection method fastens and connects the two connection ends of the conveyor belt by using hinge pins or sheet buckles. This method has the disadvantages of lar...
